Introduction Adverse changes in the tax treatment of particular securities are often accompanied by grandfather clauses that shield existing holders from the changes. If these holders consider selling their positions, they should realize that any repurchases of these securities will be subject to the new, more severe tax law. By focusing on a particular provision in the Tax Reform Act of 1986, this article illustrates how to derive an optimal investment policy in the presence of grandfather clauses. The Tax Reform Act of 1986 required property-liability insurers to reduce their tax deductions for losses by 15 percent of their tax-free income,(1) effectively raising their marginal tax rate on tax-exempt income. A grandfather clause stated that the rule applies only to income from tax-exempt bonds purchased after August 8, 1986. Effects of this change are quite important: From 1986 to 1989, over 30 percent of property-liability insurers' financial assets were in tax-exempt bonds, and these insurers held about 16.4 percent of all tax-exempt bonds outstanding (Board of Governors of the Federal Reserve System, 1990). The literature relating tax law to investment policy grew along two branches. The first derived tax-induced trading strategies under the assumption that all investors are taxed alike. For example, Constantinides (1983, 1984) and Constantinides and Ingersoll (1984) analyzed optimal deferral and realization of capital gains and losses in stock and bond markets. The second branch focused on the fact that not all investors are taxed alike. Schaefer (1982) showed that differentially taxed investors usually disagree on the relative value of securities and, consequently, choose to hold different sets of securities. Furthermore, the set of securities held by any class of investors may very well change over time. Subsequent work (e.g., Dybvig and Ross, 1986; Dammon and Green, 1987; Dermody and Prisman, 1988) analyzed equilibrium prices in the presence of differential taxation. The analysis here differs from both of these approaches. Whereas the first branch studied tax-induced trading in a particular asset, this article analyzes tax-induced trading across assets. And while the second branch studied the equilibrium implications of differential taxation, this article assumes that price movements can induce differentially taxed investors to switch from one asset to another in order to focus on an interesting investment problem. Furthermore, this is the first study of the effects of a grandfathered tax change on optimal trading strategies. The next section formalizes the investment problem of a property-liability insurer that holds exempt bonds bought before August 8, 1986. Then, using historical parameters, we show that the value of the option to switch between bond classes and the value of the grandfather clause have nontrivial magnitudes. The Model and Optimal Investment Policy This section first develops the model in the absence of capital gains taxation in order to illustrate clearly and simply the methodology and the main results. The second part of the section adds capital gains taxation to the model. No Capital Gains Taxation Assume the existence of two types of perpetuities. Both types pay $1, before taxes, each year, but the income from one type is tax-exempt, and the income from the other type is taxable. In an equilibrium characterized by differential taxation, the prices of the exempt and taxable securities will differ in a way that reflects the level of interest rates and the relative wealths of the different tax classes. Consequently, the difference between the two prices can be modeled as fluctuating randomly over time. For simplicity, we model the spread between taxables and exempts by fixing the price of the exempt perpetuity at some constant, |P.sub.E~, and letting the price of the taxable perpetuity, |P.sub.T~, fluctuate randomly. Now consider the investment decision facing a property-liability insurer. …


In order to understand the role of the acid–base, electrostatic and covalent interactions between enzyme and support, the catalytic behavior of the Rhizomucor miehei lipase (RML) immobilized on zeolite materials has been studied. The highest lipase activities were obtained when this enzyme, immobilized by adsorption, interacts through acid–base binding forces with the support surface, resulting in activation of the enzyme catalytic center. Due to the interest in biodiesel production by mild enzymatic transesterification, this heterogeneous biocatalyst has been used in transesterification of fatty acids contained in olive oil. The results show a high oleic acid conversion for several reaction cycles with a higher total biodiesel productivity compared to that using the free enzyme.


The paper gives a comprehensive study of inertial manifolds for semilinear parabolic equations and their smoothness using the spatial averaging method suggested by G. Sell and
J. Mallet-Paret. We present a universal approach which covers the most part of known results obtained via this method as well as gives a number of new ones. Among our applications are reaction-diffusion equations, various types of generalized Cahn-Hilliard equations, including fractional and 6th order Cahn-Hilliard equations and several classes of modified Navier-Stokes equations including the Leray-$\alpha$ regularization, hyperviscous regularization and their combinations. All of the results are obtained in 3D case with periodic boundary conditions.

This study is aimed to identify the character traits and find the relation to the setting of the novel. Besides that, the writer also describes how the main character"s conflict depicted in the novel. In explaining the aim of the study, the writer applies the structuralism theory by Edgar V. Roberts which emphasizes to find the relation and connection among the elements of literature. From the analysis, the writer finds that the main character"s traits are related to the setting and the conflicts that run in the plot of the novel. The main character faces two conflicts; they are external conflicts and internal conflicts. The external conflicts occur between the main character and the other characters in the novel. Meanwhile, the internal conflicts occur within the main character itself. Keywords: character traits, setting, conflicts of the characters


Preparations from the roots of the Thai medicinal plant, Tiliacora triandra Diels, were found to have antimalarial activity against Plasmodium fakiparum in vitro. Methanol extraction yielded two alkaloidal components (water‐soluble and water‐insoluble). Only the water‐insoluble alkaloidal component showed an increase in antimalarial activity. From this component, five different alkaloids of the bisbenzyl‐isoquinoline group were isolated and identified as tiliacorine, tiliacorinine, nor‐tiliacorinine A, and two uncharacterized alkaloids G and H. Alkaloid G was found to be the most active in vitro schizontocide (ID50, 344 ng/mL) followed by nor‐tiliacorinine A and tiliacorine (ID50, 558 and 675 ng/mL, respectively).


Wedding ensemble on the podium draws the attention to the author's daring ideas, unconventional image of a bride and the use of alternative materials.


essary to evaluate the intensity (flow depth, velocity and potential damage) and probability of occurrence (once every 10 years, 100 years, 1000 years?) of events likely to affect a given point in the area (a house, for instance). It is therefore crucial to take this variability into account. In this context, the scenario-based approach exemplified here can be considered a practical method of hazard assessment. It consists first in a diagnosis of debris-flow triggering processes at work in the catchment considered. Then the ranges of variation of all the inputs of a debris-flow simulation model are deduced from the diagnosis. Each of the input values is then assigned a probability of occurrence, mostly qualitative (frequent, rare, exceptional, etc.). Numerical simulations, covering these predefined ranges of variation of input data are then carried out. Each simulation result can subsequently be assigned a probability of occurrence, once again mostly qualitative. This method is here exemplified on the Rioulong torrent (Loudenvielle, Hautes-Pyrénées, France) alluvial fan, with a few houses, a camp site and a local road within the hazard zone. First, the catchment is diagnosed considering erosion processes at work in the catchment. This diagnosis means that the probability of debris-flow triggering cannot be ruled out. It also provides an evaluation of the magnitude of debris flows likely to affect the alluvial fan. In the second part of this article, a scenariobased analysis, using a numerical model dedicated to the computation of debris-flow spreading on alluvial fans, is carried out in order to assess the debris-flow hazard. In ABSTRACT A method of debris-flow hazard analysis, using the Cemagref LAVE2D model, within a scenariobased approach, is applied to a torrent of the French Pyrenees. A preliminary analysis of the catchment shows that some risk of debris-flow occurrence is present and that scenarios should be constructed accordingly. Numerical simulations are carried out on the basis of these scenarios. They produce maps of maximum extension of debris flows in relation to qualitative levels of probability of occurrence. Simulations also provide information that is useful for the design of a protection structure. Finally, the maximum extension of debris flows resulting from the presence of the protection structure is analyzed.

ABSTRACT The purpose of this study was to investigate the feasibility of arm-free standing after complete spinal cord injury (SCI) utilizing the intact part of the trunk musculature. Two paralysed subjects underwent ten days of standing in the mechanical apparatus which allowed for movements of paralysed legs in the sagittal and frontal plane while providing an adequate level of stiffness in the paralysed ankles and hips. Both subjects were able to maintain posture by means of voluntary and reflex activity of trunk muscles at the stiffness levels around 8 – 10 Nm/deg in both planes simultaneously.


The dorsal raphe nucleus (DR) is a heterogeneous brain region containing dopamine (DA), serotonin (5HT), γ -aminobutyric acid (GABA) and glutamate neurons. While transgenic mouse lines have proven to be a critical tool for manipulating DR neurons, the complexity of this nucleus requires Cre-driver lines that restrict transgene expression to a precisely defined target population. Here, we carried out a systematic evaluation of the cell-type specificity of five Cre-driver lines targeting neuromodulatory populations in the DR. We find dramatic differences in cell-type specificity between lines targeting DA neurons, and a two-fold difference in penetrance between lines targeting 5HT neurons. Using these mouse lines, we map genetically-defined DR circuits and show that neurochemically distinct populations of DR neurons are arranged in topographical pattern, send divergent projections to amygdala subnuclei, and differ in their presynaptic inputs. Strikingly, targeting the same cell population using different Cre-driver mouse lines yielded both structural and functional differences in the neural circuits accessed. Our results provide a refined model of DR circuitry, illustrate the importance of comparative analyses between transgenic lines for the interpretation of optogenetic experiments, and support a case-by-case evaluation of the suitability of any mouse line for a given experimental application. our understanding of the anatomical and functional diversity of heterogeneous brain regions. All lines have least All

Abstract This paper examines third-country passengers' travel itineraries on the DFDS Seaways ferry route linking Kiel, Germany with Klaipeda, Lithuania using a mixed-methods approach comprising qualitative and quantitative methods, including geographical information system spatial-cluster analysis. Survey results reveal the predominant third-country passenger groups (i.e. passengers from countries other than Germany and Lithuania) on ferries sailing from Kiel to Klaipeda and back were Latvian (28%), Dutch (20%), British (14%) and Danish (12%) nationals; 86% of Latvian passengers used the ferry to travel between home in Latvia and work in Western Europe. Western European passengers comprised a diverse segment of motorized tourists using the ferry in summer to reach the Baltic States faster than by land. The paper highlights the role of the Kiel–Klaipeda ferry route within the Baltic Sea motorized tourism circuit linking the Baltic and Nordic countries with Western Europe.


Interactive contribution:

Pathologists' diagnostics are based upon morphology, which means to distinguish between structure and function. Morphology is the evaluation of biological structures. These are ordered clusters of material (genes, nuclei, cells, organs, etc.) that remain constant during the period of detection and observation. The observation time is an important factor that defines biological structures and diagnostics too. The implementation of measurement - based diagnostic algorithms improves the accuracy and serves for quality assurance in tissue - based diagnosis.


This paper proposes an incremental algorithm for constructing the Delaunay overlaid network for virtual collaborative space. In our algorithm, every node uses Delaunay triangulation, by using its knowledge of other nodes and cooperatively exchanging information among nodes, which generates and refines overlaid networks. On the resultant Delaunay network, nodes communicate with each other over virtual collaborative space, and employ multihopping communication among distant nodes. This algorithm structure has the following advantages: (1) utilization of only the localized nodes, omitting the use of unnecessary distant nodes for communication, (2) scalability through surveillance of nodes by refining and updating the network continuously, (3) two dimensional space organization which allows construction of super nodes that govern regional areas to process geographical range query, and (4) directional communication through a small routing table. The authors believe that this approach is applicable to large-scale virtual collaborative space and location aware system.

AARLY twenty years have passed since Kausche, Pfankuch and Ruskal first demonstrated tobacco mosaic virus in the electron microscope. Not until five years ago, however, did detailed visualization of viruses within cells , become feasible. Although examination of thin sections at high resolution constitutes a new and important method of studying viruses, the acquisition of data is, and will continue to be, a slow process beset with difficulties. To understand the contribution that electron microscopy is making, to appreciate the nature of its limitations and to perceive the role it may play in the immediate future requires some knowledge of the instrument and the techniques currently employed. The electron microscope is essentially an evacuated tube several feet long containing three magnetic lenses and a series of small apertures. Electrons are emitted from a tungsten filament at one end and are accelerated by a strongly charged (5o,ooo-100,000 volts) positive field. As they pass down the column their direction is controlled by the magnetic fields of the lenses. Upon striking the specimen, which is inserted near the half-way mark, electrons are scattered by dense structures but continue with little deflection through areas of low density. A fluorescent plate viewed through lead glass windows near the end of the tube translates the energy of the electrons into light and thus permits the image of the section to be seen. A micrograph is obtained by flipping the fluorescent plate to one side and exposing a photographic plate immediately beneath. The electron microscope provides but one advantage over the light


This chapter describes the development of teaching thinking and its uptake in schools over the last sixty years. The influence of key individuals, research and projects, as well as developments in other fields such as neuroscience, can all be identified. From a theoretical view, there are three broad strands drawing on psychology, philosophy and our understanding of the physiology of the brain. The recent history of teaching thinking in education reflects these perspectives, however the underpinning values about thinking and learning indicate that teaching thinking is likely to remain of enduring educational interest.


Objective To discuss the relation between indexes of spleen and G/S staging in chronic viral hepatitis. Methods According to the pathology result of needle biopsy, the liver fibrosis status of 361 chronic viral hepatitis patients was graded as S0-S4,and the inflammatory reaction in the liver was graded as Gl-G4. The control group consisted of 104 healthy persons. The discrepancy of spleen indexes was compared between the case group and the control group and among G/S stagings. Results The discrepancy of the size of spleen, inside diameter of splenic artery and vein, blood flow of spleen was significant between case group and control group, and these indexes in the case group were higher than those in the control group. The values of the size of spleen, inside diameter of splenic vein and VsSPA increased as the G stagings became higher, and there was significantly difference. The discrepancy of the size of spleen, inside diameter and velocity of splenic vein, RI of splenic artery was significant among the S stagings. The discrepancy of the size of spleen, inside diameter of splenic vein and VsSPA was significant among the different patient's conditions and these indexes increased as the patient's condition became graver. The correlation coefficients between the spleen thickness and inside diameter of splenic vein, blood flow of spleen were 0.510, 0.447, respectively. Conclusion The size of spleen, the inside diameter of splenic artery and vein, the blood flow of spleen increased in chronic viral hepatitis, and with the G/S stagings increased and higher. The size of spleen, the inside diameters of splenic artery and vein, hemodynamic indexes of spleen are helpful to estimate the patient's disease.


The first colour television transmissions in Great Britain in 1967 marked the end of more than ten years of national and international debate over the technical specifications of the colour television system to be adopted on a European scale. From 1955 a group of European experts – mainly television engineers from broadcasting institutions, national post offices and the television industry – met at regular meetings of the CCIR (Comite Consultatif International de Radiocommunications) to discuss the possibilities of introducing a common European colour television standard. Engineers hoped that this would transform the fragmented European television landscape with its numerous different line standards for black-and-white television (Fickers 2006a). With the foundation in November 1962 of an ad hoc commission on colour television of the EBU (European Broadcasting Union), the discussion intensified and concentrated on comparing three existing technical alternatives: the American NTSC system, the 'French' SECAM system and the 'German' PAL system. But what started as a scientific endeavour to determine the best colour television system for Europe slowly but surely mutated into a fierce techno-political controversy between the major stakeholders. The most intense phase of the colour television debate took place between the 1962 EBU ad hoc commission meetings and the 1965 and 1966 CCIR conferences in Vienna and Oslo. While both contemporaries and historians have described this European debate as being primarily a French-German argument (Fickers 2007), the interests and influence of the British television industry, the broadcasters and various political institutions including the Post Office, the Foreign Office and the Board of Trade have received less academic scrutiny. This article highlights the interferences of technical, industrial and political interests in


The manufacturing industry has been an important sector in the Malaysian economy for the past three decades. The important role of this industry to the Malaysian economy today is not only because Malaysia depends substantially on manufacturing for its foreign exchange earnings, but also because Malaysia is the main exporter of electrical and electronic products. This study examines the structural changes in the Malaysian economy by utilising two economics tools, namely, the econometric approach using the Autoregressive Distributed Lag (ARDL) model and the input-output approach using Structural Decomposition Analysis (SDA). These two approaches are used to analyse the sources of growth in the manufacturing sector in Malaysia. From both economic approaches, ARDL and IO, the results agreed on the importance of the domestic consumption effect as a source of growth in the economy. The empirical results from this study are very useful guide to the manufacturing industry for the need to generate more domestically oriented products.


Data obtained using three different sampling gear is compared and combined to assess the size composition and density of a non-indigenous snow crab population Chionoecetes opilio in the previously free of alien species Kara Sea benthos. The Sigsbee trawl has small mesh and catches even recently settled crabs. The large bottom trawl is able to catch large crabs, but does not retain younger crabs, due to its large mesh. Video sampling allows observing larger crabs although some smaller crabs can also be spotted. The combined use of such gear could provide full scope data of the existing size groups in a population.


This paper improves on the widely used residual method in order to estimate the magnitude of capital flight in eight Asian economies over the period of 1980–2004. The paper argues that as capital flight is a drain on financial resources for development, it is more appropriate to measure it against the size of the financial market, which can be proxied by money aggregate, in contrast to the common practice of measuring it as a percentage of gross domestic product. Using this more appropriate new measure, we find that capital flight is more severe in some financially underdeveloped countries than has been suggested previously. It is also found that while capital flight could be a dormant sideshow in a benign economic environment, it could have considerable impact on the availability of financial resources when activated.


the visual acuity dropped from 20/30 to 20/60 OS. Gonioscopy revealed a cyclodialysis cleft in the area of the surgical iridectomy. The retinal examination findings were noted to be normal by the glaucoma and retinal subspecialists. Stratus OCT showed retinal folding consistent with hypotony maculopathy (Figure 3A). The patient was given 1% atropine, and the IOP increased to 52 mm Hg with presumed closure of the cyclodialysis cleft. The use of glaucoma medications reduced the IOP to 16 mm Hg. After the glaucoma medication was tapered, the IOP stabilized in the 11to 13-mm Hg range. Best-corrected visual acuity improved to 20/30 OS with resolution of retinal folds on Stratus OCT (Figure 3B).


This paper details with the developing of the age dependent face recognition system. The YCbCr and HSV colors paces are applied to skin detection and face region extraction. The proposed method preserves the identity of the subject while enforcing a realistic recognition effect on adult facial images between 15 to 60 years old that are divided into 11 classes with 5 years old range. The age of the input individual is predicted to examine the related age group. Eigen face approach is applied to both the training data and each aging group of database. And, then the face recognition is performed with a predicted aging group. Based on the principal component analysis method and Kth nearest neighbor classifier, the face recognition system is developed. The proposed system will reduce the complexity and processing time dramatically by considering the dependent aging groups of an individual instead of the whole database.


In this study, we investigated a noncontact method of measuring plastic strain of metals using laser speckle. This method is based on observation of the change in laser speckle pattern with surface profile change due to plastic deformation. Analysis of the laser speckle pattern is performed on a computer-based image processing system. The relationships between speckle pattern and surface roughness and frequency characteristics of the surface profile were investigated. Surface roughness and surface profile were observed for steel specimens polished with emery paper or plastically deformed. The surface profile diagram was analyzed by means of the fast Fourier transform with a computer and distribution of the spatial frequencies was obtained. The results showed that distribution of light intensity of the speckle is related to frequency distribution of the surface profile, but it is not always related to surface roughness. It was also clarified that the laser speckle pattern is closely related to the magnitude of plastic strain.


According to the housing situation of different regions and different income groups of urban residents, the scientific measurement of public rental housing demand is the basis for the preparation of housing security planning. Public rental housing needs of different cities should consider the regional urban population distribution, city housing prices and residential housing consumption ability, the immigrant population, the city level and scale, and other factors. We take Zhejiang province as an example, explore the public rental housing demand of different cities, and try to provide a reference for public rental housing construction planning and related policy formulation.


"Risk" is widely used to explain an event pertaining to the probability of an outcome to occur. This paper provides the review of risk from its origin, where the concept of risk has been a concern for humanity since days of old, without the usage of its proper terminology. The study relies solely on related literature and highlights the application of risk in Islamic finance. Reviews of previous studies normally have its own terminology in research methodology. This section covers the issues of how risk is defined by researchers in various disciplines and therefore, how it is specifically related to Islamic finance through a generic and unique name, that is, Shariah risk. The major issue highlighted is where the sources are, which led to a deviation from the path that creates harmful effects. There are other sources for the risk that still need to be clarified further, but this study revealed the sources that lead to the changes of circumstances which result in having risks, based on the Quranic evidences in Islamic perspective. Hence, this paper aims to fill the gap of the current literature by showing the need to conduct further research on the derivation of Shariah risk and its potential in determining capital requirements in Islamic financial institutions.


Unmanned Underwater Vehicles have become very important requirements today as they can perform a wide variety of operations in an underwater environment. With the increasing worldwide use of Remotely Operated Vehicles, the necessity of enhancing operator efficiency has emerged, therefore, the Autonomous Underwater Vehicles have become highly desirable for that purpose but the cost of controlling Autonomous Operated Vehicle is significantly expensive than the Remotely Operated Vehicles. As exemplified above, both types of underwater vehicles have several advantages and disadvantages. The UUV presented in that paper has the basic features of both vehicle types and it's controlled by adjusting the thrust forces generated by the six thrusters with the help of a closed-loop control system developed. The dynamics of the UUV has been derived from Newton-Euler equations and the Euler angle representation has been used to define rotations of the UUV. Since the Euler angle parametrization contains singularities around 90 degrees of pitch angle, a passive stability mechanism has also been created mechanically on the vehicle beside the software preventions. A parameter identification approach to make a minimum number of assumptions on the dynamic model has been presented. This paper considers the mechanical design, mathematical modeling and control of an Unmanned Underwater Vehicle that covers the features of both remotely and autonomously operating underwater vehicles.


The aim of this study is to determine the level of knowledge of primary school teachers about the concept of early literacy, to determine whether this knowledge level differs according to the teachers' gender, the type of school they graduated from and their professional seniority; to reveal the importance of early literacy skills for 1st grade students of primary school and how to increase teachers' early literacy knowledge levels. This research is a descriptive study of the nature of a survey model. In this study, in which quantitative and qualitative research techniques were used together, mixed method was used in data collection and analysis. The study group of the research consists of 52 primary school teachers who teach the 1st grade. While schools were determined through the disproportionate stratified sampling, teachers were determined through simple random sampling. The analysis of the qualitative data was conducted via content analysis while the quantitative data were analyzed via independent group t-test and ANOVA in this study for which data collection was provided via a semi-structured interview form developed by the researchers. Research findings reveal that primary school teachers have low knowledge levels regarding early literacy and their knowledge levels do not vary depending on gender, the type of school they graduated from and professional seniority. In classroom teaching departments, courses with well-prepared content on early literacy should be put in place, effective in-service training activities should be organized on the subject and classroom teachers should be exchanged frequently with their preschool teachers.

Novel (arene)titanium(II) haloaluminate complexes (η6-arene)Ti[(μ-X)2AlX2]2 (X = Cl, Br) were obtained from (η6-benzene)Ti[(μ-X)2AlX2]2 (X = Cl, Br) complexes by ligand exchange reactions with bis(pentamethylphenyl)methane and dimesitylmethane. The [η6-1,2,3,4,5- pentamethyl-6-(2,3,4,5,6-pentamethylbenzyl)benzene]Ti[(μ-X)2AlX2]2 (X = Cl, Br) and [η6-1,3,5- trimethyl-2-(2,4,6-trimethylbenzyl)benzene]Ti[(μ-Br)2AlBr2]2 complexes containing titanium coordinated to only one of the two phenyl rings were obtained and their crystal structures were determined. (η6-Benzene)Ti[(μ-Cl)2AlCl2]2 and dimesitylmethane afforded the (η6-mesi- tylene)Ti[(μ-Cl)2AlCl2]2 complex which is isotypic with the known bromo analogue. This product shows that Friedel-Crafts scission of aryl-alkyl bonds occurs in such systems even under mild conditions.

This thesis investigates bank behavior and its real effects, in the context of the ECBs Long Term Refinancing Operations. Specifically, I investigate the effect of changes in sovereign debt portfolios of European banks and their determinants following the LTROs, as well as the resulting real consequences for firms that rely on such banks for debt financing. I find that some banks are motivated by factors other than value or risk to expand their sovereign debt exposures. Specifically, my results suggest that GIIPS banks actively increase their (risky) domestic sovereign debt exposures (risk-shifting) directly following the LTROs and that this effect is not influenced by the degree of government control (moral suasion). In addition, I find that such risk-shifting bank behavior has negative real consequences for firms, in the form of lower EBIT in the period following the LTROs. My findings emphasize the relevance of adequate bank supervision regarding the destination of funds supplied by open market operations. More stringent supervision may prohibit banks from using the funding to bet on the survival of certain sovereigns and would thus limit the negative real effects that result from such bets.


The tax revenue of the Republic of Bulgaria has been analyzed in terms of consumer tax system. Two sub-periods have been covered - at economic growth and at crisis. The results show that in the first case, the revenues from indirect and direct taxes form the necessary budget funds, as in the second case - they are insufficient. There are prerequisites for increasing the national debt as a result of lower tax revenues in terms of crisis.


The process of quality management involves everyone who participates in construction because of their equal contribution to the final quality of the construction work. Due to the project management it is possible to achieve total required quality. It is important to get every participant organized in a way to ensure all the requirements to be met and to have satisfactory work quality. Through efficient procedures, everyone controls himself and can later guarantee other participants that every activity has been performed as required by investor. Council Directive of 21st December 1988, on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (89/106/EEC) is the basis for the harmonization of building regulations within the European Union. The Directive contains all the requirements needed to achieve quality construction work through the harmonization of standards' application and by defining technical approvals, essential requirements, conformity certificate and authorization of supervising bodies. The basic documents given in the Chapter IV of the Directive define in detail all the essential requirements. They refer to all construction works and member states of the European Union have to act accordingly. They refer to: mechanical resistance and stability ; safety in case of fire ; hygiene, health and environment protection ; safety in use ; noise protection ; energy efficiency and heat retention. These essential requirements are obligatory also in the Croatian Law on Construction. According to this Law, the construction project has to meet the essential requirements within anticipated life-time provided that it has been maintained on a regular basis. The process of certifying quality management systems in construction firms in Croatia, which has been initiated to meet the standards of ISO 9000 series, as well as the authorization of testing laboratories according to standards HRN EN ISO/IEC 17025 and HRN EN 45011, enables meeting of the essential requirements for construction works as regulated by the Law on Construction. The standards of ISO 9000 series, stimulate the adoption of a process approach in the development, implementation and improvement of the quality management systems.


Records of recent changes in growing ice-contact lakes in the Bhutan-China border region are investigated using satellite imagery. The results show that lake growth has continued at a growth rate of< 70 m/year in length and < 0.04 km2/year in area. In the debris-covered area of the glacier, the lake expands in stages through the initial appearance of supraglacial lakes and subsequent expansion of a coalesced lake. In the small debris-free or partially debris-covered glacier, the lake expands simply from a single lake. The initial year of appearance of most of the lakes at the southern and northern sides of the Himalayan mountains ranges from the 1950s to the 1970s and before the 1950s, respectively. Furthermore, the trace of the glacial lake outburst flood (GLOF) in the Hinku valley, and the present situation of the glaciers and the glacial lakes in the Hongu valley in eastern Nepal are confirmed by the field survey. Many boulders and coarse sands generated from the GLOF in 1998 remain distinctly and continuously at least 10 km downstream from the collapsed lake as a bare river bed with thick debris flow deposit. The assessment considered that there are no serious conditions regarding the GLOF given the present situation of both valleys. Comparison with previous data shows that the retreat speed of glaciers at the headwater of the Hongu valley is approximately 8 m/year.


Inelastic scattering of 500-Mev negative pions has been investigated in 1700 meson-induced events in emulsion nuclei. Large energy losses and strong angular relationships of the emitted mesons have been observed, similar to those in experiments with lower energy mesons. The possible causes for this behavior are discussed. In 1-3 percent of the events, production of charged mesons has been found. The cross section for meson production on free nucleons is estimated to be between 3.5 and 10 mb, considering the possible absorption of one or both mesons. The angular and energy distributions of mesons and recoiling nucleons in events with meson production are discussed. Six events of ${\ensuremath{\pi}}^{0}$ production on free protons (or edge nucleons) have been found. The results are compared with observations on meson scattering and meson production in cosmic-ray experiments.


This study of quantitative determination of nitrite and nitrate contents is based on spectrophotometric measurement of the red colour formed when sulphanilic acid is diazotised by the nitrite to be determined and coupled to 1-naphthylamine-7-sulphonic acid (Cleve's acid 1-7). Nitrate is first reduced to nitrite in a cadmium reducing column.

Good results have been obtained with some horticultural and meat products and samples of soil.


The invention relates to an anorthite intermediate used as an industrial kiln high-temperature heat-insulating material. A calcium silicate material, an aluminum silicate material, other aluminum-containing and/or calcium-containing materials, and the like are adopted as raw materials. Silica sol and cellulose or/and polyacrylamide are adopted as binding agents. The anorthite intermediate is prepared by adding water, mixing, performing compression molding and drying. The anorthite intermediate has good mechanical strength and heat insulating performance, can be converted into anorthite resisting to higher temperatures by reactions in a using environment with high temperatures of an industrial kiln, and can resist a temperature of 1200 DEG C.


The goal of human genome project is to characterize and sequence entire genomes of human and several model organisms, thus providing complete sets of information on the entire structure of transcribed, regulatory and other functional regions for these organisms. In the past years, a number of useful genetic and physical markers on human and mouse genomes have been made available along with the advent of BAC library resources for these organisms. The advances in technology and resource development made it feasible to efficiently construct genome-wide physical BAC contigs for human and other genomes. Currently, over 30,000 mapped STSs and 27,000 mapped Unigenes are available for human genome mapping. ESTs and cDNAs are excellent resources for building contig maps for two reasons. Firstly, they exist in two alternative forms--as both sequence information for PCR primer pairs, and cDoreen genomic libraries efficiently for large number of DNA probes by combining over 100 cDNA probes in each hybridization. Second, the linkage and order of genes are rather conserved among human, mouse and other model organisms. Therefore, gene markers have advantages over random anonymous STSs in building maps for comparative genomic studies.


The invention relates to a simulated touch evaluation method for the surface quality of a material. The simulated touch evaluation method is characterized by comprising the steps of constructing a simulation measurement platform; suspending a textile test sample to generate deformation; enabling a bionic skin to do controlled multidirectional and multipoint contact motion relative to the textile test sample; simulating contact friction conditions under different touch speeds and different average touch forces; and calculating a simulated touch sensing signal. The simulated touch evaluation method can be used for vividly simulating a process of obtaining surface quality information when a human body touches a fabric with a finger and vividly simulating a real contact friction process between the skin of the human body and the fabric; tested force and vibration signals are analyzed through a human body touch sensing mechanism, and a corresponding relation of the signals is found according to the sensitivity of different touch sensors to different stimulations, and therefore, quantification and evaluation of touch of the human body on the surface quality of the fabric are realized.


The superheated steam temperature control is an important part in the boiler control system of power stations.As the superheated steam temperature has large inertia,time-delay and nonlinearity,and its dynamic characteristics change with the operating conditions,a self-tuning PID controller based on fuzzy-RBF(Radial Basis Function) neural networks is presented for its control,which has the advantages of traditional PID control,neutral networks control and fuzzy control and on-line optimizes PID parameters.Its application in a supercritical unit is introduced.Simulations under 100 %,88 %,62 %,44 % unit load conditions validate its better performance than normal PID controller.


Molecular beam mass spectrometry has been used for an in situ study of the Pt-catalyzed formation of hydrocyanic acid from methane and ammonia. The goal was to identify transient gas phase intermediates which would indicate homogeneous contributions to the reaction mechanism. A catalytic wall reactor operated at 1300 °C, 1013 mbar, and 74% HCN yield was connected via a molecular beam interface with a quadrupole mass spectrometer, which allowed the measurement of ionization- and appearance potentials by electron impact. Shape and width of the electron energy spread function were determined by analyzing the ionization efficiency curve of helium; the experimental uncertainty of the measured threshold values was found to be 0.6 eV. By use of the threshold ionization technique it could be shown that methylamine (CH3NH2) and methylenimine (CH2NH) are present in the gas phase under reaction conditions. The measured threshold potentials at m/z
 = 30 u (9.9 ± 0.6 eV) and m/z
 = 29 u (10.6 ± 0.6 eV) were unambiguously assigned to the appearance potential of CNH4+/CH3NH2 and the ionization potential of CNH3+/CH2NH, respectively. Both molecules dehydrogenate rapidly at reaction temperature to HCN so that they can be considered as true gas phase intermediates.


45 patients (50 eyes) were treated for juvenile rhegmatogenous retinal detachments between August 1979 and July 1984. A review of these cases revealed high myopia and trauma to be the main aetiological factors. Eight-six per cent detachments were successfully reattached. Visual acuity of 6/36 or better was present in 16% preoperatively and in 52% postoperatively, Some of the characteristics of juvenile rhegmatogenous retinal detachments in Malaysian population arediscussed.


This Project has as a main objective the proposal of the creation of a Recreational Tourist Establishment in Crucita, Manabi Province. As Crucita is a place with growing tourism nowadays and has a permanent tourist population all year long, this Establishment would be a perfect proposal to diversify the offer of recreational tourism. To commit this offer, it is proposed that this Establishment should have restaurant-bar service, bicycles and table games rental, internet and phone service rental, adequate showers and toilets, and as a plus it should offer quality service and tourist information, that it is not found anywhere in Crucita. It is proposed the use of this place as a diffusion tool of Crucita as a destiny of varied activities during the day, matching the sport activities (parapente) which practiced in this beach daily. As last objective it is recommended to work with the people from Crucita, previously capacitated, for their economics and life quality improvement. To complete this project, it was also realized a complete finance study which presents its viability, appearing attractive to investors, besides a environmental study and its mitigation plan.


This letter presents a Lyapunov function based control strategy for networked control systems (NCS) affected by variable time delays and data loss. A special focus is put on the reduction of the computational complexity. The crucial step to achieving computational efficiency involves defining a specific buffering mechanism that introduces an additional delay not larger than one sampling period. This allows representing the buffered NCS as a switched system, thus leading to a significant simplification of the NCS model and subsequent controller synthesis. The novel approach does not only circumvent the need for any over-approximation technique, but also leads to a strongly decreased number of optimization variables and linear matrix inequalities, allowing hereby greater flexibility with respect to additional degrees of freedom affecting the transient behavior. The performance and computational efficiency of the control strategy are demonstrated in a simulation example.


In the paper some evaluates of pure ice and hydrodynamic resistance of the vessel with the help of CAE systems. It was noted that, in General, the identification of the hydrodynamic resistance of the vessel for the conditions of pure water and in ice incorrectly. It is shown that the conditions of application of approximate methods of numerical simulation of the motion of the vessel in the ice is determined by the level of significance of ice and hydrodynamic loads on the hull of the vessel.


Against the background of the slow adoption of the Internet as a channel of retail distribution, the primary objective of this study was to investigate perceived risks associated with intention to purchase online on a generically-branded website. A secondary objective was to examine the influence of brand image and information search behaviour on perceived risk, by investigating whether these two variables can act as intervening variables in influencing consumer intention to purchase on a generically-branded website.
Of the different types of risk perceptions investigated in this study, only performance risk influenced the intentions to purchase on a generically-branded website. The study also found that brand image mediated the influence of performance risk on intentions to purchase on a generically-branded website. Enhancing the brand image would thus lower concerns about the performance risk associated with a generically-branded website. Information search intentions did not, however, mediate the influence of performance risk on intentions to purchase on a generically-branded website. Thus, adding additional information on the website that consumers may find useful will not reduce performance risk or increase intentions to buy.


This paper examines the processes that bring about the creation of new public-space CCTV schemes. Through an appraisal of the grounded activities of the practitioners who make decisions over CCTV, the role of agency is identified as a particularly strong, yet relatively neglected, influence on its implementation. Moreover, beyond dichotomised notions of central structures and local agency, an understanding is developed of the complex interaction between the individual actors involved in CCTV dissemination and the political context in which they operate. In doing so, public policy is identified as the vehicle through which camera surveillance systems become installed and disseminated throughout public space. Moreover, these various forces of structure and agency become filtered through identifiable networks of policy-makers, comprising 'responsibilised' actors who oversee the deployment of CCTV. This analysis is used to revisit a range of administrative and theoretical understandings of surveillance, including: citations of CCTV as an evaluated response to crime; the attribution of power- and interest-based agendas to its implementation; and accounts which locate CCTV expansion within various evolving societal processes. Drawing on qualitative fieldwork data gathered during doctoral research, the paper considers the activities of practitioners at a local level and identifies crucial contexts, drivers and negotiations on which expanding surveillance is contingent. Ultimately, it is argued that the process of CCTV installation – from conception to material implementation – is disrupted and mediated by a range of micro-level operations, obligations, processes, managerial concerns (particularly conflict resolution and resource issues), structures and agency, and the indirect influence of central government. These not only arbitrate over whether the CCTV becomes installed, but also generate a range of additional uses for the cameras, many of which are performed before they are even switched on. This emphasises the need to consider the processes that enable and constrain the actions of those making decisions over CCTV and demonstrates how no single interest becomes solely participant in the deployment of surveillance. Finally, because of the centrality and contingency of both human agency and the structural contexts in which it operates in determining the installation of CCTV, questions arise concerning the importance of integrative sociological theories in understanding the deployment of surveillance.


Abstract
 This chapter explores gender-specific dimensions of so-called 'climate-induced migration' and elucidates their relevance for research on climate change, gender, and livelihoods in the Global South. To this end, the chapter starts with a brief overview on the state of the scientific debate on the interlinkages of climate driven environmental change and migration, followed by a discussion of conceptual approaches applicable for the inclusion of the gender dimension. The chapter provides empirical evidence for gender relevance using a case study on the West African Sahel and ends with some considerations on policy issues and further research. In doing so, the chapter illustrates in which way a 'gender lens' adds to more robust knowledge and in what way the perspective of social ecology is of particular value.


Giant Canada geese (Branta canadensis maxima), which are nesting locally in Northwest Ohio and other parts of the state, are commonly perceived as a public nuisance when they inhabit urban areas. The feces of giant Canada geese litter both grass and pavement in many occupational and recreational sites in the Toledo area. The purpose of this study was to identify sites with fecal droppings of giant Canada geese that test positive for Cryptosporidium, Giardia, and Campylobacter, qualitatively assess the occupational risks of infections, and recommend protective measures. The fecal droppings of giant Canada geese were tested for Cryptosporidium, Giardia, and Campylobacter, using sensitive monoclonal enzyme immunoassay (EIA) methods. Fourteen out of 16 sites tested positive for at least one pathogen. None tested positive for all three. Cryptosporidium was the most common infectious organism found in the fecal droppings. It was detected in 14 out of 18 (77.8%) samples. Campylobacter was found in 7 out of 18 (3...


This paper compares the status of the research which followed the nineth centennial of the death of Pier Damiani (1972) with that accrued at the millennium from his birth (2007), which, besides by a greater accessibility of sources, is characterised by a better contextualisation of the activity of the "Avellanita", whose complex profile has recently been redefinded.


E-learning programs bring new challenges and opportunities to community colleges. This chapter identifies twelve maxims for developing and sustaining a successful program, and illustrates the ways in which one community college has applied them.


This article tackles the issue of the genre inscription of the last tale of Cervantes' Novelas ejemplares . It proposes, among other things, that Coloquio de los perros , through ironizing different degrees of verisimilitude, cancels all possibility of attaching any central meaning to Berganza's account of his life as a dog. After revisiting some critical accounts, it sets this work in the literary tradition of Menippean satire and the comic-serious genres, as theorized by Bathin, pointing out its links to Lucian. The paper also stresses the role and function of heteroglossia and inserted genres in Coloquio de los perros , as well as other intertextual relations deployed in this tale.


The goal of the present study is to characterize solutions under a travelling wave formulation to a degenerate Fisher-KPP problem. With the degenerate problem, we refer to the following: a heterogeneous diffusion that is formulated with a high order operator; a non-linear advection and non-Lipstchitz spatially heterogeneous reaction. The paper examines the existence of solutions, uniqueness and travelling wave oscillatory properties (also called instabilities). Such oscillatory behaviour may lead to negative solutions in the proximity of zero. A numerical exploration is provided with the following main finding to declare: the solutions keeps oscillating in the proximity of the null stationary solution due to the high order operator, except if the reaction term is quasi-Lipschitz, in which it is possible to define a region where solutions are positive locally in time.


The aim of this study is to examine the stress levels of educational administrators and methods of coping with stress. One of the most important criteria for schools to be able to achieve the goals they have determined in advance, that is, to be effective, is school principals as an administrator. The task of the school administrator is to evaluate the resources in the school in the most efficient way, in accordance with the goals of the school. School principals have very important tasks in reducing or eliminating the existing sources of stress in the school environment. A good education manager is someone who tries to get to know his staff and can also deal with their problems. For this reason, they should be able to provide professional guidance, especially to newly appointed education administrators, from the preparation of plans to the solution of in-school and out-of-school problems, as well as provide the moral support they will need. He should be able to use his authority to eliminate or reduce the sources of institutional stress. School and course schedules should not be changed every year unless they are needed by education administrators. Changes should be made only in accordance with today's requirements. The problem of overcrowding of classrooms must be solved. This can be solved by allocating more financial resources to the education sector, by making new schools and appointing enough teachers. Since schools are one of the most stressful environments of our society, education managers are one of the most important building blocks of this environment. Education administrators are Decently acting as a bridge between National Education and teachers, teachers and students, and teachers and parents. All problems that may occur in the working environment are tried to be resolved by contacting the school principal. In this case, it is inevitable that education managers will encounter the most commonly used word today, namely "stress". In the rankings of stress sources that affect education managers the most, it is observed that the management understanding factor usually ranks first. Efforts to manage the school, which are seen as a critical factor in educational administrator stress, are perceived as highly stressful. Key Words: Education Manager, Stress Levels, Methods of Coping with Stress


A swimming suit with buoyance is composed of an upper wear, a waist band and a swimming pants, all of which can be easily assembled together or dissembled from each other and have the floating blocks with the buoyance ratio of (20-25%):(45-55%):(25-35%).


Emission spectral tomography (EST) can be utilized to reconstruct three-dimensional (3D) physical parameter distributions of gas flow fields. Mostly, the radiant energy of the visual and near-infrared bands is received by a video camera in EST, so it is difficult to examine a low/medium-temperature gas flow field by normal EST. However, the far-infrared radiant energy of a low/medium-temperature gas flow field is strong enough to be received by a far-infrared detector. Based on EST, a far-infrared band computed tomography (FICT) approach is proposed that focuses on far-infrared spectral emission and band emission tomography. Both low- and medium-temperature blackbody furnaces were adopted to calibrate the relation between infrared thermal image intensity and radiant exitance. The 3D temperature reconstruction of an alcohol blow lamp was carried out. According to the results of multiple measurements, the relative error of the FICT approach is less than 20%. The experimental results prove the feasibility of the FICT approach.


In this paper, we deal with the problem of synthesizing novel motions performed by a pair of human-like characters while reflecting their interactions. Adopting an example-based paradigm, we address three non-trivial issues embedded in this problem: motion labeling, interaction modeling, and motion coupling. For the first issue, we provide a genetic search scheme for motion segmentation and classification, exploiting the structural and geometric features of motion segments. For the second issue, we propose a coupled movement transition graph to capture the interactions between the two characters and their individual behaviors. Based on a coupled hidden Markov chain, the transition graph is trained with example motions. For the last issue, we propose a scheme for synthesizing a novel sequence of coupled movements guided by the transition graph. We believe that our method can be used for two-character motion synthesis in game production.


Wireless Data dissemination is an effective way to disseminate large amount of data to a large mobile user population. Our project, called "DAYS (DAta in Your Space)", investigates information management issues in wireless space. One of the main objectives of DAYS is to build a system to provide transactional and web services facilities globally. This paper discusses the creation of a location domain and proposes an algorithm for creating location dependent data. A new indexing scheme for ac- cessing Location Dependent Data (LDD) in DAYS has also been presented which not only provides a bound on the access time but also allows significant energy conserva- tion in mobile devices.


A low temperature bonding technology for SiC power devices bonded to an active metal brazed copper on Si3N4 substrate is successfully realized using a transient liquid phase sintering (TLPS) method with a nano-composite Cu/Sn paste. The bonding process of the paste is composed of two steps. The first step is the TLPS reaction of the molten Sn with Cu powder. The second step is the solid state reaction between Cu6Sn5 and Cu which forms Cu3Sn. Differential scanning calorimetry (DSC) analysis is used to evaluate the reaction temperature of the TLPS process. The solid state reaction of the Cu3Sn phase formation is investigated with X-ray diffraction (XRD) analysis. It is found that the completion of both the TLPS reaction and the solid state reaction is realized at 280 deg C for 20 min. The microstructure change of each reaction step is analyzed with a scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDX). Based on the results mentioned above, the bonding process conditions of temperature and time is determined. SiC devices are bonded to an active metal brazed copper (AMC) on Si3N4 ceramic substrate using the nano-composite Cu/Sn paste. The shear strength of the bond is 39 MPa, which is about 6 times higher than the IEC standard. Since these reactions are completed at the bonding process temperature of 280 deg C, the shear strength is not affected by the process temperature over 280 deg C. The shear strength at 400 deg C is also measured and 18 MPa is obtained even the devices are bonded at 280 deg C. The proposed bonding method with the nano-composite Cu/Sn paste is a promising technology for 250 deg C-operating SiC power modules, because the process temperature is close to the operating temperature of the devices.


This paper presents the control algorithm and design of a pipe crawling robot which can be used for the purpose of earthquake rescue and pipeline maintenance. The robot is designed to be able to intelligently alter its body shape to fit the pipe or tunnel-like voids within rubble. The paper introduces a simulation to test how the robot alters its body shape to fit voids. The control algorithm uses a look-up table method combined with the method of least squares to predict the shape of the robot under the influence of actuators. The paper also presents the design of both the hardware and software systems of the robot, and laboratory experiments on the robot body module. Computer simulation results by using MATLAB and the experimental results indicate the feasibility of the robot body shape change control algorithm proposal.


In this paper, we present a novel method image retrieval model for mobile product image searching system. For feature extraction, a method integrating Speeded Up Robust Features (SURF) and Local Binary Pattern (LBP) is proposed. SURF is invariant to rotation, scaling, translation and have low calculated cost, so SURF is quite suitable for mobile product image search model. However, SURF is not effective with the noisy images, blur images, illuminated images. Because LBP operator is invariant to changes in illumination and contrast of images, we use LBP to supplement for disadvantages of the SURF features. Our proposed method can improve accuracy and speed of the system. For query, a query model using K-NN Search with vector quantization is used. This model improve performance and reduce the cost of computation of the mobile product image searching system. The experimental results show the feasibility of our proposal model.


We study the influence of initial defects in high-resistance epitaxial silicon layers of high-resistance epitaxial silicon structures on defect formation processes at ion boron doping. The method of reverse voltage-capacitance characteristics revealed two maxima of dopant concentration in epitaxial silicon layers ion-doped by boron. Studing the structure of the near-surface area in ion-doped epitaxial silicon by means of modern methods has shown that in the field of the first concentration maximum (the nearest one to a wafer surface), the fine-blocked silicon structure is localised. In the range of the second doping concentration maximum, the grid of dislocations with the variable period within one grid and consisting of 60° dislocations is found out. In the area of dislocation grids, oxygen atoms have been found out. The variable period in the grid is related with a change of mechanical stress and deformation distribution law in the plane of dopant diffusion front as dependent on the presence of initial defects in silicon.


When I think back to conversations I have had with women, I still feel uneasy as I recall in appropriate, thoughtless or perhaps naive comments that I have made in the course of a day's work.


The fluid-structure interaction of a NACA 643618 airfoil is numerically simulated using the software ANSYS 12.0. The airfoil is equipped with an elastic mounted flap, which allows a camber change when aerodynamic loads are applied. The stiffness of the torsional movement is used to adjust the deflection angle. The investigation focuses on load alleviation for modern wind turbines. The specifications are taken from the NREL 5 MW Reference Wind Turbine undergoing changes in angle of attack and incoming flow velocity due to atmospheric wind shear. The results show the influence on the resulting tangential (i.e. in-plane) and normal (i.e. out-of-plane) coefficients. The aim is to reduce the magnitude of force coefficient changes. This reduction results in decreased fatigue loads. It was found that the load reduction potential increased with descreasing stiffness of the flexible trailing-edge flap and that the magnitude of this reduction was largely independent of the exact design point used for determining the preload-moment.


Increasing and indiscriminate use of antibiotics for human, veterinary, aquaculture and agriculture along with contamination of water and soil by pharmaceutical industries is the major of increased antimicrobial resistance in recent times. Among the microbes resistant to different drugs, urinary tract infections (UTI) are found to be the highest contributors to antibiotic resistance in microbes. The present study was intended to contribute towards the determination of prevalence of antibiotic resistance of Klebsiella pneumoniae, among patients suffering from urinary tract infections who visit hospitals for treatment. Among 2011 samples tested for UTI, 386 (19.34%) samples tested positive. Klebsiella accounted for 90 (23.23%) of the positive cases tested, and the isolates were extended-spectrum -lactamase (ESBL) producers with very high resistance to quinolones, aminoglycosides, carbapenems, and sulfamethoxazole-trimethoprim, but were susceptible to polymixins, Nitrofurantoin, and levofloxacin. The highest prevalence was found among women within the age group of 24-27 years. Of the 90 isolates, 42 isolates were multi drug resistant (MDR) and 48 isolates were non-MDR. Molecular identification using 16S rDNA analysis showed that the isolates were highly resistant organisms and possessed a similarity of more than 99% with UTI isolates reported to have antibiotic resistance.


The paper describes an experimental determination of the usefulness and limitations of elementary theory in estimating the fields scattered by metal wires and sheets, treated as passive scattering-elements. The results are of interest in assessing errors due to obstacles on a direction-finding site. Formulae are derived for the scattered fields, using the transmission-line theory for wires and diffraction theory for sheets. A method is described for the measurement of scattered fields and the results of measurements on various wires and sheets, at a frequency of 600 Mc/s (50 cm), are shown to be in substantial agreement with the elementary theory. The measured amplitudes of the resonance peaks which occur in the field scattered by a wire as the length of the wire is varied are, however, much smaller than would be expected, except for wires less than two wavelengths long. The results indicate that for wires of the order of 1-mm diameter resonance effects at a frequency of 600 Mc/s are small if the length of the wire is more than about five wavelengths. This conclusion is probably true for a wide range of wire diameters and frequencies. Resonance effects in sheets may be neglected if the dimension of the sheet normal to the electric vector is greater than a wavelength. It is concluded that scattered fields may be computed from elementary theory to the accuracy normally required in direction-finding work.


We present a novel non-symmetric bis-acylurea that self-assembles into two dimensional nanosheet superstructures. The bis-acylurea (PyrC8Bn) has a pyridyl and a benzyl end group divided by a spacer group [–NHCONHCO–(CH2)8–CONHCONH–, C8] with two hydrogen bonding sites. Upon cooling a hot solution in ethanol, the molecule self-assembles into multilayered nanosheet structures due to the intermolecular biaxial hydrogen bonding. The surface charge of the nanosheets could be switched between positive and neutral by adjusting the pH. The charged character of the nanosheets was utilized in immobilizing negatively charged gold nanoparticles. An attempt to regulate the self-assembly allowed us to find a unique hierarchical structure of PyrC8Bn, where ultrathin (<10 nm) 2D lamellae growing within microspheres were observed. This superstructure with large surface area could serve as a template for inorganic catalytic materials.


Reproductive characteristics during the estrous cycle of red panda(Ailurus fulgens) in captivity were reported.Five adult females were selected for this study.With radio-immunoassay,serum concentrations of estradiol and progesterone were assessed 23 times consecutively during estrous and gestation period from December 2005 to July 2006.Results: Several concentration peaks of estradiol appeared during the estrous,only one peak was associated with mating.The duration of estrous period lasted from 14 days to 48 days,and the average was 28.26±13.24 days(n=5).Estradiol concentration peaks also appeared in the pregnant animals and non-pregnant animals(pseudo-pregnant) during their expected gestation period.Serum concentrations of progesterone were elevated in 5 animals during their expected gestation period,and were risen soon after mating.Conclusions: Red panda may be polyoestrous during the estrous season.The follicles could be still developing during luteal phases in the pregnant animals and non-pregnant animals.There is no evidence of embryo delayed implantation in red panda in captivity of Fuzhou area according to appearance of serum concentrations of progesterone.


With the aim of shedding light on issues surrounding the development and evaluation of report, this paper offers a theory for facilitating and legitimizing an accountability‐based discourse and disclosure in the public health sector. The project adopts Laughlin's (1995) vision of middle range theory and an accountability perspective to justify the form and normative perspective which shapes the skeletal model to follow. Formulated in part from an analysis of the health management and public sector accounting literatures, the model is now empirically supported from the preferences of health sector accountees in New Zealand. The result is a conceptual construct which is both considerate of and challenging to the standard financial accounting model. The skeletal model consists of five conceptual categories, their interrelationships and properties. The theoretical model considers and mandates illumination of political incentives, incorporates the assumption that accounting can be constitutive as well as reflective and is sympathetic to a wide range of interests and contextual distinctions.

Abstract Two kinds of synthetic methods for the organic donor molecule BEDT-TTF or ET [bis(ethylenedithio)-tetrathiafulvalene] are reviewed and compared. Through detailed and systematic studies of the synthesis of BEDT-TTF, a convenient, reliable, ready and high-yield synthetic procedure is presented, which is superior to the methods reported to date in terms of the yield and reproducibility.


The dynamics of Rydberg states of atomic hydrogen perturbed simultaneously by a static electric field and a resonant microwave field of elliptical polarization is analysed in the quantum perturbative limit of small amplitudes. For some configurations, the secular motion (i.e. evolution in time of the elliptical electronic trajectory) may be classically predominantly chaotic. By changing the orientation of the static field with respect to the polarization of the microwave field, one can modify the global symmetries of the system and break any generalized time-reversal invariance. This has a dramatic effect on the statistical properties of the energy levels.


As pressures from development and climate change grow, land managers are turning to introductions/assisted migrations to prevent rare species extinctions. When introducing a species, it is important that propagules survive long enough to reproduce and recruits establish and reproduce themselves. If the target specie's specific microsite and regeneration requirements are unknown, one can use experimental introductions to learn demographic information while attempting to create a new population. Planting into three distinct microsites within its native habitat, I used the introduction of the endangered plant, Tephrosia angustissima var. corallicola, as an opportunity to answer microsite-specific questions while attempting to establish a new population. Results showed the highest transplant and recruit growth, flowering, and survival occurred in shady, dry microsites; recruits germinated in shadier locations than where adults were planted. Lessons learned from introduction successes and failures are essential to building the scientific base needed for rare species conservation and policy decisions. iii To my friends and family who supported and encouraged me to succeed. iv ACKNOWLEDGEMENTS Without the help of the following people and organizations, I would not have been able to accomplish this degree. I thank Dr. Joyce Maschinski for her help throughout the project with research design, project development, and encouragement. I thank my advisors for their comments and critical feedback making this a stronger paper; most notably, Dr. Peter White for his help in navigating through the process and constructive advice. Much appreciation and thanks goes to Dr. Jack Weiss for his endless patience and assistance with the data analysis. Thanks,Tropical Horticultural Station (Raymond Schnell) for permitting us access to the wild population.


After received harsh critiques in 2016, once more, a rumor about the construction of a bridge between Java island and Bali island has been sparking wildly since January 2020. Previously, Banyuwangi Regent Azwar anaz proposed a plan to build a connecting bridge to reduce vehicle queues in ketapang harbor. Commonly, the traffic would reach its peak time on holiday season after Eid al-Fitr, where congestion in Ketapang harbor got its limit capacity. For decades, the Bali strait has been serving as a connecting port between Java and Bali, which is essential for economic growth and public migration. Meanwhile, philosophically, the strait holds a symbol of new hope and new life that separates between past and future. A rumor to build an overpass between java island and Bali island discussed in early 2020 and in 2016 to reduce vehicle queues in ketapang harbor received critiques from Balinese society. To connect the two islands by land route would be considered a poor decision since it would affect some values and cultures that the community, especially Bali, holds dearly. Thus as an alternative solution, the idea of making another dock, an executive dock, both in Ketapang and Gilimanuk, is much preferred. The presence of the executive port will automatically eradicate the resurgent discourse on the Java-Bali bridge construction. Because crossing via ship alone takes 15 minutes, thus the Java-Bali bridge seems unnecessary. The executive pier would be in synergy with the construction of the Denpasar - Gilimanuk toll road.


" F or elegant and excellent was the pirate's answer to the great Macedonian Alexander, who had taken him: the king asking him how he durst molest the seas so, he replied with a free spirit, 'How darest thou molest the whole world? But because I do with a little ship only, I am called a thief: thou doing it with a great navy, art called an emperor.'" St. Augustine, The City of God , Book IV, Chapter IV. There is a description of piracy that spans the ages: illegal and armed aggression at points of maritime traffic that are important but under weak political control. The aggression is committed by the marginal who seek to appropriate the wealth of the more affluent, or by new-comers desiring to force their way into preexisting trade routes. This elementary description tells us about plundering and illegality; it tells us about immediate causes and motivations. But it leaves out the questions of what law is invoked against the pirate, and behind the law, of what power is involved in this maritime confrontation over matters of trade. In the rise of merchant empires at the beginning of the modern era that is the focus of this book, what is called piracy is also easily recognizable. From sea to sea and age to age, we observe the same phenomena appearing – at once picturesque, violent, and sordid.


Abstract Introduction. Recent investigations have emphasized the need for university teachers to de-velop tutorial programs for students at university. Many universities are committed to broad-ening research on university teaching that will sharpen academic performance and levels of student satisfaction. Tutoring programs improve the development of the teaching-learning process and reduce student drop-out rates. However, it is necessary to step up teacher training in the evaluation of prior knowledge, in procedures for continuous assessment and in teach-ing-learning methodologies for project-based learning. Likewise, instruments with high levels of reliability and validity are needed, to measure the effectiveness of these tutorial-programme-based techniques. The objectives of our study are twofold: to validate a scale for measuring the development of the Tutorial Program and to test whether the department to which the teacher-tutor belongs influences the evaluation of the Tutorial Program.


This paper presents a three-phase approach to find the correspondence in Target Language (TL) sentence for a fragment of Source Language (SL) sentence in a lexicalized EBMT system. To be practical, it exploits surface information as much as possible instead of using parsers. Experiments show that, although not so perfect, it is very robust and effective. The three phases are: First, align the sentence pair at word level in order to provide anchors for phrase alignment. Second, based on the aligned anchors, find all the TL fragments which may possibly correspond to a SL fragment. And finally, using a score function, select the best TL fragment as the correspondence of a SL fragment.


.. Granulosa cell tumour (GCT) along with concurrent dermoid cyst involving the same ovary is very rare. Nine such cases have been reported in the literature. Most of the reported cases are seen in older patients. Here we present a case of a young female with granulosa cell tumour and dermoid cyst in the same ovary.


The measures taken to control the impact of the COVID-19 pandemic, such as social distancing and the closure of educational institutions, have had a major impact on the normal development of learning activities. Laboratory activities have been greatly affected due to their practical and face-to-face nature. This study carries out a systematic review of different approaches used to transform face-to-face laboratories into virtual and remote laboratories. Both quantitative and qualitative analyses have been carried out on a sample obtained from the Scopus database (n = 13), identifying the type of documents, relationship between authors and documents, collaboration index, as well as the country where the experience was carried out. The areas of knowledge and the tools used in them have also been described. The results show that all articles were published in 2021, most of which were multi-authored articles with a collaboration rate of 4.8. The country in which most experiences were developed was the USA, the knowledge area with the most studies was biology and the most used tool, in combination with others, was videoconferencing. Only one of the experiences took advantage of immersive technology or virtual reality to set up a virtual laboratory.

This paper examines the wavelength assignment problem for single, dual, and multimessage multicasting over a star network with optical switching between fibers along the same wavelength. The specific problem we consider is given any star network, a predetermined number of fibers that connect its nodes, and a set of multicasts (or multidestination messages) to be delivered in one communication round, find a conflict free message transmission schedule that uses the least number of wavelengths per fiber. When the least number of wavelengths, λmin, exceeds the number available, λavl, one may transform the schedule into one with ⌈λmin/λavl⌉ communication phases or rounds over the same network, but restricted to λavl wavelengths per fiber.


We investigate the forming of gamma-ray burst pulses with a simple one-dimensional relativistic shock model. The mechanism is that a "central engine" drives forward the nearby plasma inside the fireball to generate a series of pressure waves. We give a relativistic geometric recurrence formula that connects the time when the pressure waves are produced and the time when the corresponding shocks occurred. This relation enables us to relate the pulse magnitude with the observation time. Our analysis shows that the evolution of the pressure waves leads to a fast rise and an exponential decay pulses. In determining the width of the pulses, the acceleration time is more important than that of the deceleration.


Objective To Investigate clinical efficacy and mechanism of Qilong capsule in treatment of patients with acute cerebral infarction.Methods 100 patients with acute cerebral infarction were randomly divided into 2 groups:the control group was treated with conventional therapy, while Qilong capsule group was treated with Qilong capsule in addition.The changes of European stroke scale(Ess) score and activities of daily living(ADL) score,the plasma contents of tissue-type plasminogen activator(t-PA),plasminogen activator inhibitor-1(PAI-1),TXB_2 and 6-Keto-PGF1a were observed before and after treatment.Results The scores of Ess and ADL in two groups after treatment were remarkably increased.Compared with the control group,the scores of Ess and ADL were higher in the Qilong capsule-treated group,the differences were significant (P0.05,P0.01).On the other hand,the contents of t-PA and 6-Keto-PGF1a were significantly increased,while the contents of PAI-1 and TXB_2 were lower in the Qilong capsule-treated group compared with control group,the differences were statistically significant(P0.01).Conclusions Qilong capsule can improve clinical therapeutic effects,the mechenism may be related to the effects of accelerating fibrinolysis and inhibiting activity of platelet.


The optical characteristics of polymethylmetacrylate (PMMA) can be changed selectively with the aid of ion implantation. This can be explained by the manner in which the chain molecules are decomposed by the bombardment. New binding states can be identified by means of XPS on the irradiated surface and traced throughout the implantation depth using dynamic SIMS. In order to avoid chemical reactions, inert gas ions, ranging from He to Xe, have been implanted at energies between 100 keV and 380 keV, and fluences from 1 × 10 13 /cm 2 to 7 × 10 15 /cm 2 . The results indicate a correlation of the refractive index and the surface layer contraction with surface CH- and COH-groups generation (XPS) and with in-depth damage described by the emission of secondary ions with masses 26 and 42 (SIMS), assigned to (CH 2 )- and (C 2 OH 2 )-.


This paper deals with a monolayer graphene based wideband reflective cross polarization converter metasurface structure effective over a wide range of incident angles in the lower terahertz gap of the electromagnetic spectrum. The unit cell of the metasurface comprises a modified split ring-shaped graphene pattern deposited over a gold backed silicon dioxide (SiO2) substrate. The proposed geometry converts incident linearly polarized (LP) wave to its cross polarized form with a near unity cross polarization conversion (CPC) ratio over a bandwidth of 2.53 THz in the lower terahertz gap ranging from 1.78 THz to 4.31 THz in which a near unity polarization conversion ratio (PCR) has been achieved. The PCR is greater than 0.9 over the band 2.5 THz to 4 THz while full width at half maxima (FWHM) fractional bandwidth of 92.89% with respect to center frequency of 3.05 THz has been realized. The wide bandwidth of CPC of the incident electromagnetic wave (EM) occurs till 40º incident angles under both TE and TM polarizations of the EM wave. The proposed CPC is ultrathin in nature by having a periodicity of λ/24 and thickness of λ/18.7 with respect to minimum frequency of the CPC bandwidth.

We present a computer model for the acquistion of programming languages from textbooks. Starting from a verbal description of the notational conventions that are used to describe the syntactic form of programming commands, a meta grammar is generated that parses concrete command descriptions and builds up grammar rules for that commands. These rules are realized as definite clause grammar rules that captures the syntax of these commands. They can be used to parse and generate syntactically correct examples of a command. However, to solve real programming problems also the semantics of a command and of its parameters needs to be acquired. This is accomplished by the natural language parsing of the explanations given in the text and the augmentation of the definite clause command grammars with semantic structures.


Previous studies have shown that quinoxaline (Q) o xidation with electrochemically regenerated KMnO 4, with the formation of pyrazine-2,3-dicarboxylic acid (PD CA), is possible using Pt, Ni, stainless steel and Cu electrodes. In order to improve current knowledge and to expand th e variety of electrodes used for the pyrazine-2,3-d icarboxilic acid (PDCA) production process, we investigated the beha vior of the copper alloy anodes – brass and bronze. A laboratory electrolyser for PDCA synthesis with copper alloy a node was manufactured. Depending on the anode – cop per, brass and bronze the effect of various parameters on the cu rrent and substance efficiencies was investigated. These parameters are: anodic current density, amount of electricity, temp rature and initial concentration of quinoxaline. T he best performances of this electrolyser are ~88% current efficiencies on the brass electrode and up to 80% substance effi ienc es on the bronze electrode, at a current density of 3,5 A/dm . These performances are greater than those obtaine d on the copper anode.


Background and purpose:Bleeding or thrombotic diseases are easily to be found in ovarian cancer patients,because the balance of their coagulation system are being undermined due to tumor burden or surgery.We studied the value of plasma D-dimer monitoring before and after ovarian cancer surgery.Methods:The plasma concentration of D-dimer levels were measured in 161 ovarian cancer patients and 41 benign ovarian tumor patients,and then we followed up to analyze the change of D-dimer concentration of 23 postoperative patients.Results: The plasma levels of D-dimer in ovarian cancer patients were found to be significantly higher than those in ovarian benign tumor(P0.01).Significantly differences of D-dimer levels were found among different ovarian cancer stages(χ2=78.894,P0.01),which suggested that ovarian cancer patients' coagulation and fibrinolysis dysfunction become more serious during the progression of disease.The D-dimer amount kept at a high level or raised suddenly after a transient decrease in 9 patients who were seized with thrombotic diseases after operation.Conclusion:Monitoring the plasma D-dimer level before and after ovarian cancer operation could help finding out those who have high probability of thrombotic diseases and preventing deep venous thrombosis after operation.It also helps us to strive for early prevention,early diagnosis,early treatment,and to improve the prognosis of the patients.


ABSTRACT Introduction: The review aims to discuss effects of vitrectomy on pharmacokinetics of anti-vascular endothelial growth factor (anti-VEGF) agents, and attempt to provide treatment guidance. Areas covered: An Embase search was conducted using the terms 'anti-VEGF', 'pegaptanib', 'ranibizumab', 'bevacizumab', 'aflibercept', 'pharmacokinetics', 'half-life', 'clearance', 'metabolism', 'vitrectomy', 'vitrectomized'. Published data regarding the pharmacokinetic properties of the above drugs and the effect of vitrectomy in animal and human eyes was reviewed. Expert opinion: There are limited studies on the effect of vitrectomy on pharmacokinetic properties of anti-VEGF drugs in human eyes. Most animal models indicate that intravitreal drugs have reduced half-lives and increased clearance in vitrectomized eyes. More studies, with carefully selected design, are required to explore this further. However, considering existing evidence, it is important to consider vitreous and lens status when monitoring and treating patients. Authors recommend fixed monthly dosing, with low threshold for increasing frequency of injection even to 2-weekly if required, as well as close monitoring of patients to establish individual response. There may be an increased role for slow-release steroid implants in vitrectomized eyes with DME or RVO. Longer acting substances currently under development such as brolucizumab or abicipar pegol, may become the treatment of choice in the future.


Cold rolling and hot stretching (105°C) both lead to increased failure stress and decreased stress whitening in model ABS composites while hot stretched samples alone retain a tensile yield dip. Further differences between hot stretching and cold rolling are revealed in electron micrographs obtained by the Kato method. In the hot stretched samples the ruber particles appear as elongated "cigar-like" smooth ellipsoids which reflect the observed macroscopic orientation. SAN occlusions within the ruber particles are deformed to the same degree as the rubber. Ruber particles in cold rolled samples, however, exhibit a jagged, "hairy" surface indicating a high degree of shear distortion; and SAN occlusions within the rubber particles are not deformed in rolling. The rubber particles in cold rolled ABS are flattened and disk-like rather than ellipsoidal.


In this paper, we take our theoretical point of departure in recent work in organisational economics on systems of human resource management (HRM) practices. We develop the argument that just as complementarities between new HRM practices influence financial performance positively, there are theoretical reasons for expecting them also to influence innovation performance positively. We examine this overall hypothesis by estimating data . Using principal component analysis, we identify two HRM systems which are conducive to innovation. In the first one, seven of our nine HRM variables matter (almost) equally for the ability to innovate. The second system is dominated by firm‐internal and firm‐external training. Of the total of nine sectors that we consider, we find that the four manufacturing sectors correlate with the first system. Firms belonging to wholesale trade and to the ICT intensive service sectors tend to be associated with the second system. While creativity is generally of three types, viz. individual creativity, group/team creativity and organizational creativity, this study focuses only on organizational creativity. This study portrays a model aimed to investigate the relationships between employability, leader member exchange, innovative work behaviour, and objective- and perceived organisational performance. It also includes the moderating effect of organisational politics upon these relationships.


The data obtained from chest computed tomography (CT) can be analyzed not only visually, but also quantitatively. Quantitative assessment allows a more accurate and objective evaluation of the disease severity. Densitometry is the most researched way to quantify CT data – automatic analysis of lung densities expressed in Hounsfield units. This review is focused on the types of diseases that can be characterized by the formalization of the diagnostic task and application of densitometry, as well as on the limitations of the method and the ways to cope with them.


Abstract A control method is proposed which permits the application of the relatively simple time-optimal feedback control laws for the double and triple integrator plants to a wide range of more general second and third-order plants having real non-positive eigenvalues. The method, which is based on a state-variable transformation technique, gives time-optimal control for certain plants with eigenvalues in a simple ratio. In other cases the control is sub-optimal and yields settling times typically within 2% and 4% of the corresponding optimal value3 for second and third-order plants, respectively. Thus one may avoid the difficulty of synthesizing- the logarithmic, exponential or other complicated functions of state variables which are generally present in the exact time-optimal control laws (where known) for such plants.


Interaction of bulk gravitons to Standard Model particles is examined in the scenario of warped extra dimension. It is found that the length of the extra dimension is of physical importance as it determines the decay widths of graviton Kaluza-Klein modes. We show that cosmology as well as collider signals of the Kaluza-Klein modes are very different for different choices of the length of the fifth dimension.
