Branching habit necessarily figures prominently in breeding goals for radiata pine in New Zealand. Past breeding has pursued two extremes of regular branch habit: what are effectively short internodes and long internodes respectively. The former, which has featured in the mainstream of the breeding programme, embodies indirect selection to control branch size and angle. However, it does not allow long clear-cuttings without pruning, unlike the latter. Despite much progress towards achieving these two ideotypes, the outcome has not been fully successful. The short-internode option has given insufficient control of branch size, while poor wood stiffness further downgrades the product for structural purposes. The long-internode option, pursuing 'uninodal' trees, allows quite long internodal clear-cuttings, but has shown even more than its anticipated drawbacks. Alternative ideotypes now proposed for providing internodal clear-cuttings have two co-equal branch clusters per annual shoot, over a considerable length of bole; branch clusters could be equidistant from each other, or else closely spaced towards the end of the annual shoot. Other possible ideotypes might be favoured for specific site types. Clonal forestry seems necessary to capture such ideotypes, and even then, capturing them poses major challenges. The ability to rejuvenate clonal material at will would be a very powerful tool for this, to avoid prolonged testing of huge numbers of candidate clones.


The authors deal the problem of preparing preschool children for safe activities and safe behavior in the article. The authors analyzed the scientific and theoretical provisions that reveal the key concept of the research «safe behavior». The authors emphasize that the formation in preschool children of the foundations of safe behavior in various spheres of life (social, natural, domestic) should be considered as a priority direction of preschool education. An important task in working with preschoolers is the upbringing of a child motivated for self-preservation, capable of responsible behavior in the environment, strictly following the rules behavior. The purpose of the article is support of the substantiation of the methodological foundations for the formation of ideas about safe behavior in preschool age. The authors believe that it is advisable to use three groups of methods in the formation of ideas and skills of safe behavior in preschool children: increasing cognitive and emotional activity, establishing connections between different types of activities, correcting and clarifying ideas. There are examples of methodological techniques in each group of methods in the article. The authors make conclusion that the formation of ideas about the foundations of safe behavior allows to educate the child's self-preserving behavior, which determines the complex solution of this problem in the process of interaction among teachers, parents and pupils.

A procedure has been developed for the determination of picogram quantities of U in biological matrices by isotope dilution mass spectrometry that uses artificially produced /sup 233/U (SRM 955) as the isotopic spike. The U is chemically purified by anion exchange chromatography and then loaded onto a single anion exchange bead. The bead is loaded into the mass spectrometer and provides a point source for the emission of U/sup +/ ions with an ionization efficiency of 0.2%. One-hundred picograms of U can be measured with a precision of better than 0.5% (2s). At these levels the chemical blank is the limiting source of error. For this quantity of U the blank correction and its associated uncertainty were typically 4% and 2%, respectively. The procedure was applied to the determination of U in SRM 1577a, bovine liver, which was found to have a mean concentration of 709 +/- 13 pg of U/g (ts, 95% confidence limit), the lowest certified U concentration of any biological SRM.


The design and fabrication of a polymer optical waveguide based true time delay (TTD) device is described. Optimization of the fabrication process decreased the waveguide propagation loss from more than 1.55 dB/cm to 0.38 dB/cm at a wavelength of 1.55um. Waveguide bend loss structures were fabricated and measurement results were compared to simulations. A bend radius of 3 mm provides low insertion loss and small device size. 2x2 thermo-optic TIR switches were fabricated with insertion losses of 2.8 dB. A 4-bit TTD device for use with a 4x4 sub-array of a 10GHz phased array antenna was calculated to have an insertion loss of 23.88 dB.


In this paper we present the deployment algorithm for femtocells in capacity-limited scenario. We consider the operator-deployed femtocells that extend outdoor coverage to the areas that are poorly served by the existing macro-cellular network. To satisfy the interests of WSP and customers we propose an automated tool that carefully plans the femto-deployment. Our objective is to deploy femtocells in a single macrocell to satisfy the current traffic demand of the network and not to exceed the budget constraint for WSP. The proposed deployment algorithm PDA is based on geometrical segmentation of macro-cell, heuristic levels of traffic intensity and user distribution. To estimate the PDA effectiveness we suggest two simple deployment algorithms: SDA1 and SDA2. Also, we carry out a cost analysis to evaluate the economical perspectives of the deployment for WSP. Finally, three deployment algorithms with respect to number of installed femtocells, number of supported users and profits for WSP are investigated. Through simulations we show that the proposed deployment algorithm PDA surpasses among two other simple algorithms.


This paper deals with energy management in a district where multiple buildings can communicate over a time-varying network and aim at optimizing the use of shared resources like storage systems. We focus on building cooling, and propose an iterative, distributed algorithm that accounts for information privacy, since buildings are not required to disclose information about their individual utility functions and constraint sets encoding, e.g., their consumption profiles, and overcomes the communication and computational challenges imposed by centralized management paradigms. Our approach relies on a methodology based on proximal minimization that has recently appeared in the literature. Motivated by the structure of the considered energy management optimization program, we provide a theoretical extension of this novel methodology, that is applicable to any problem that exhibits such structural properties. The efficacy of the resulting energy management algorithm is illustrated by means of a detailed simulation based study, considering different network topologies.


I recently read Lichtenstein's compelling supplement, "Dietary Fat and Cardiovascular Disease: Ebb and FlowOver the Last Half Century," that traces the evolution of US dietary guidelines from the 1970s in the context of dietary fat and reviews the controversies and current evidence of dietary fat and cardiovascular disease (CVD) (1). However, the author's characterization of the evidence from randomized controlled trials (RCTs) in the section titled "Dietary Fat and Cardiovascular Disease: Present" starkly contrasts with that of a recent comprehensive review of the meta-analytical evidence (2). In opposition to the AHA Presidential Advisory on Dietary Fats and Cardiovascular Disease (3), the review of meta-analyses of RCTs found that the Advisory's core trials were not representative of the best available evidence and, because their recommendations hinge on the "core" trials, the strength of their recommendations was overstated (2). Although predefined inclusion criteria are commendable and transparent, it does not preclude researchers from evaluating the quality of the 4 "core" trials included.


ABSTRACT Fatigue-free and highly c-axis oriented Bi3.2La0.8Ti3O12 (BLT) thin films were deposited on p-type Si(100) substrate by chemical vapor deposition process. The BLT thin film began to crystallize at 550°C which was about 100°C higher than that of the film deposited on Pt substrate. The annealed and as-deposited BLT films on Si had the intermediate layer of about 4 nm. The concentration (at.%) of Si, Bi, La, and Ti element in the intermediate layer of the film deposited at 400°C was 61.0, 20.2, 3.3, and 15.5, respectively and that of the film annealed at 650°C or at 750°C was about the same at 57.4, 24.8, 3.1, and 14.7. 2Pr and Ec of the films annealed at 750°C were 0.3 μC/cm2 and 160 kV/cm at an applied voltage of 5 V, which is sufficient to induce the inversion layer at the Si surface. The ferroelectric capacitor of the BLT film on Si showed practically no polarization fatigue after switching up to 1.0 × 109 cycles. Higher annealing temperatures (750°C) will result in a rougher sample surface and a higher leakage current due to the crystallization of the BLT film. The film annealed at 650°C, showed the leakage current density of 1.43 × 10−9 A/cm2 at 5 V.


A parametric model of IP-networks in the form of colored Petri net was developed; it consists of a fixed number of Petri net nodes and is invariant regarding the topology of the network, number of attached routers and terminal equipment. The build parametric model does not require the modification of its structure that reduces the model construction time for a network with an arbitrary number of devices and allows the performance evaluation. The model adequacy is confirmed comparing with real-life networks.


Objective To investigate the inhibitory effect of Salvia miltiorrhiza on differentiation of skeletal muscle-derived stem cells into myofibroblasts.Methods MDSCs in SD rats were isolated by differential adhesion method.Differentiation of MDSCs was induced by transformation growth factor-β1 ( TGF-β1 )administration.The cells cultivated in vitro was divided into three groups:control group (A),10 μg/LTGF-β1 group ( B),10 μg/L TGF-β1 + 150 mg/L Salvia miltiorrhiza group (C).The mRNA expression levels of α-smooth muscle actin (α-SMA) and Vimentin in each group were detected by quantiteve realtime reverse transcription-polymerase chain reaction (qRT-PCR) and there protein secretions were detected by Western blotting.Results As compared with group A,the mRNA after TGF-31 intervention and protein expression of α-SMA and Vimentin at the 3rd,4nd,6nd,8nd day in groups B and C were prominently increased (P < 0.05 ).As Compared with group B,the mRNA and protein expression levels of α-SMA and Vimentin in group C were obviously down-regulated (P < 0.05 ).Conclusion Salvia miltiorrhiza could inhibit myofibroblastic differentiation and further ameliorate fibrosis of denervated skeletal muscles.

Mixed oxide samples of Sn1 − xTixO2
(0.0 ≤ x ≤ 1.0), prepared by the co-precipitation method followed by heating at variable temperatures, have been investigated by powder X-ray diffraction and 119Sn MAS NMR spectroscopy. Based on powder X-ray diffraction studies, the formation of solid solutions has been observed for samples annealed up to ≈800 °C. Annealing of the samples with 0.2 ≤ x ≤ 0.8 at higher temperatures led to their decomposition into two phases with a rutile structure, one being rich in Sn4+ and the other in Ti4+. Based on the comparison of the 119Sn MAS NMR spectra of the single phase and phase separated compositions, it is inferred that the cation distribution is non-random even for the samples which exhibited single phase formation.


A method, a system, a transmitter and a receiver defining a header protection mechanism for DVB MPE (Multi- Protocol Encapsulation) section protocol is provided, which is used in DVB-T mobile reception. MPE section in this case is referring to a proposal for using MPE section MAC (Media Access Control) bytes 1 - 5 to carry real time information related to time slice bursts. By using header protection mechanism together with high level FEC (Forward Error Correction), there is a way to enhance significantly mobile digital broadband data reception capabilities. The header protection used together with the high level FEC in DVB provides an advantageous solution for DVB mobile burst data reception. All packets having an uncorrupted MPE section header is put into an array for higher level error correction such as FEC. The array has addressable storage locations of mobile digital broadband data for correction of higher level data entity by FEC process. At the receiver the packet is put into a buffer. A header is identified and checked against errors by using CRC (Cyclic Redundancy Check) for the received header data. If the CRC indicates substantially correct value or is OK, the address of the packet is extracted. The packet including the header is put into the array.


Cost-effectiveness analysis is a collection of methods for comparing the costs and health benefits of one intervention with another. These methods are


The Benjamin–Bona–Mahony equation describes the unidirectional propagation of small-amplitude long waves on the surface of water in a channel. In this paper, we consider a family of generalized Benjamin–Bona–Mahony–Burgers equations depending on three arbitrary constants and an arbitrary function G(u). We study this family from the standpoint of the theory of symmetry reductions of partial differential equations. Firstly, we obtain the Lie point symmetries admitted by the considered family. Moreover, taking into account the admitted point symmetries, we perform symmetry reductions. In particular, for G′(u)≠0, we construct an optimal system of one-dimensional subalgebras for each maximal Lie algebra and deduce the corresponding (1+1)-dimensional nonlinear third-order partial differential equations. Then, we apply Kudryashov's method to look for exact solutions of the nonlinear differential equation. We also determine line soliton solutions of the family of equations in a particular case. Lastly, through the multipliers method, we have constructed low-order conservation laws admitted by the family of equations.


The powder is pressed into different shapes under high pressure in the order of 1 ton / cm. For each core size, a pressing tool is necessary consisting of at least two parts. The resulting so‐called "green bodies" are then sintered at up to 1,400°C under defined atmosphere. During many hours or even days, some grains will grow at the cost of others, the free volume between the grains disappears, i.e. the bodies are compacted and shrink significantly, and grains are connected and separated finally by thin grain boundaries with different chemical and structural properties. The most critical property of these boundaries are the insulating properties and thus, these act as capacitor with the neighboring grains. It is worth noting that structural changes which occur during this sintering process determine the final properties. This is an essential difference to metal powder cores.


We study how the shape of parts obtained through the LASER cladding process can be controlled by application of an ac magnetic field by means of two simple physical models: a numerical and an experimental one. More specifically, we show that straight metallic joints of high aspect ratio can be obtained by using inductors of triangular cross-section that concentrate electromagnetic forces at the bottom of the joint. The effect is first demonstrated on a numerical model for an infinitely long joint such as: we illustrate how the joint shape can be controlled by varying the inclination of the inductor and for a magnetic Bond number Bom=60 (which measures the ratio of electromagnetic to capillary forces), we obtain a joint of aspect ratio up to 7.2. We further find that inductor angles in the range 15°–25° lead to joint side faces that are close to vertical. These findings are then verified experimentally by placing a liquid metal drop in a purpose built inductor of triangular cross-section. We find a good ag...


Background Sudden Infant Death Syndrome, (SIDS) or cot death, remains the most common category of post‐perinatal death in the UK. By definition, the cause of death is unknown, but a long‐standing theory is that some of these deaths could be the result of anaphylaxis.


Four genera of cheloniid (Caretta, Chelonia, Eretmochelys, Lepidochelys) and one genus of dermochelyid (Psephophorus) sea turtles are recorded from the Bone Valley Formation of central Florida. The fossils derive from phosphate deposits of early Pliocene (late Hemphillian) age, 4.5-5 Ma. Although similar in age to fossils from the Yorktown Formation (Lee Creek Mine) in North Carolina, the Bone Valley sea turtle fauna appears to lack two genera found at Lee Creek (Syllomus, Procolpochelys) and contains one genus that is not found at Lee Creek (Eretmochelys). The Caretta from the two areas may not be conspecific. The fossil Chelonia, Eretmochelys, and Lepidochelys cannot be distinguished confidently from modern species, but conversely only the Lepidochelys appears obviously related to a particular modern species, L. kempi. This paper provides the first report of Eretmochelys in Pliocene deposits and the first association of Psephophorus with all living cheloniid genera except the Australian Natator. We suggest that shallow seas in the Bone Valley region provided rich feeding habitat for sea turtles in the early Pliocene in the same way that shallow water habitats in Florida and the Bahamas support a similar assemblage today. The Bone Valley phosphate mining region of central Florida long has been known as a rich source of terrestrial and marine vertebrate fossils (Sellards, 1916; Allen, 1921; Simpson, 1930; Kellogg, 1944; Brodkorb, 1955). Phosphatic sediments of the Bone Valley Formation in this region have produced a sequence of vertebrate faunas dating from the middle Miocene (about 16 Ma) to the early Pliocene (4.5 Ma) (Webb and Hulbert, 1986). The best known Bone Valley fauna is early Pliocene in age and has been referred to the late Hemphillian North American Land Mammal Age (NALMA; Berta and Morgan, 1985; Webb and Hulbert, 1986; Tedford et al., 1987). Following Webb and Hulbert (1986), we use the term Palmetto Fauna to distinguish the late Hemphillian vertebrate assemblage from older faunas present in the Bone Valley region. The Palmetto Fauna contains a fossil assemblage representing marine, estuarine, freshwater, and terrestrial components, and appears to have accumulated at a time when sea levels were about 50 m higher than present (Webb and Tessman, 1968; MacFadden and Webb, 1982). The marine and estuarine components consist of sharks, rays, bony fish, sea turtles, pelagic birds, and many marine mammals, including a walrus, three species of seals, a sea otter, a sea cow, and numerous cetaceans (Berta and Morgan, 1985). The presence of sea turtles in late Hemphillian age deposits in the Bone Valley region was noted briefly by Berta and M rgan (1985) and Dodd (1990), but these fossils have not been previously described. Tertiary sea turtle fossils have been described from a number of localities on the Atlantic Coastal Plain, including the Paleocene Hornerstown Sand and Vincetown Formation and Eocene Manasquan Formation of New Jersey (Weems, 1988), the Paleocene Brightseat and Aquia Formations of Maryland and Virginia (Weems, 1988), the Oligocene Ashley Formation of South Carolina (Hay, 1923), the Miocene Kirkwood Formation of New Jersey (Zangerl and Turnbull, 1955; Weems, 1974), the Miocene Calvert Formation of Maryland and Virginia (Weems, 1974, 1980), and the Pliocene Yorktown Formation in North Carolina (Zug, in press). The very few published records of Tertiary sea turtles from the Gulf Coastal Plain include a questionable Eocene dermochelyid from Alabama (Thurmond and Jones, 1981) and a middle Eocene cheloniid from Florida (P. Meylan, 1984). There also are some unreported cheloniid fossils from Florida, mostly consisting of shell fragments, from the middle Eocene Avon Park Limestone and Inglis Formation and the Oligocene Suwannee Limestone (G. Morgan, unpubl. obs.). A few Florida Pleistocene fragments belonging to modern genera (Chelonia, Caretta) were mentioned by Hay (1916, 1917), but no comprehensive summary or description of these fossils is available. One of the largest collections of Tertiary sea turtle fossils in North America is from the Lee This content downloaded from 188.8.131.52 on Sat, 27 Aug 2016 04:05:15 UTC All use subject to http://about.jstor.org/terms C.

PAUL KLEE'S ANGELUS NOVUS (1920) has accrued almost iconic status because of its appearance in one of the most famous passages of Walter Benjamin's 'Theses on the Philosophy of History'. The image of the Angelus, which is held at the Israel Museum in Jerusalem, has become a sort of cipher for Benjamin's influential historical materialist ethics. Given its cultural significance, when the artist R. H. Quaytman was permitted to view the work in 2013 she assumed she would have nothing to say about it that had not already been said. When she looked at the monoprint, however, she noticed that the thin, dark margin surrounding the figure was part of an older mechanically produced engraving 'so devalued that no one had even noticed it'. After two years of research, and with help from several specialists, she identified the obscured image from a digital database of over 60,000 engravings. It transpired that Klee had pressed his angel onto a mass-produced copy of a 1521 portrait by Lucas Cranach the Elder depicting Martin Luther, leader of the Protestant Reformation, whose writing was used to justify anti-Semitic violence from the late nineteenth century through to the Nazi dictatorship. The spectral presence of Luther beneath


Plasma proteins are produced and secreted at high levels by hepatocytes. The most abundant is albumin. The remainder are a heterogeneous group of glycoproteins, several of which have important homeostatic functions. This review will focus on two plasma proteins whose physiological effects expand the already extensive functional repertoire of liver-secreted proteins: plasminogen, which modulates breakdown of extracellular matrix (ECM) through its activation to plasmin; and collagen XVIII, which is a basement-membrane protein. Recent studies indicate that plasminogen is the precursor of angiostatin and collagen XVIII is the precursor of endostatin. Both angiostatin and endostatin are polypeptides that inhibit endothelial cell proliferation, angiogenesis, and tumor growth in experimental models of cancer. Hepatocytes appear to be the main source of these proteins, normally synthesizing and secreting them into plasma, and thus may influence extrahepatic endothelial growth.


Permanent magnet Brushless DC (BLDC) motors are gaining popularity mainly because of their better characteristics and performance in comparison to other electrical motors. BLDC motors are generally controlled using a three phase power semiconductor bridge. For starting and providing proper commutation sequence to turn on the power devices in the inverter bridge, the rotor position sensors are required. Based on the rotor position, the power devices are commutated sequentially every 60 degrees. This paper presents MATLAB/SIMULINK based simulation of BLDC motor drives. BLDC motor drive operates in six modes for one complete revolution of the rotor. The complete analysis of six modes of operation with position of rotor has been presented in this paper. The switching of the IGBT switches and corresponding phase currents and line voltages are shown here for each sequence. The presented BLDC motor drive is based on hysteresis band PWM current controller for generating modulated switching signals.


The generation of burden-of-disease (BOD) data has been driven by a desire to inform policy making and priority setting. This chapter examines the uses of BOD data for priority setting. The authors first introduce the most relevant BOD metrics and describe how these have been linked to priority setting. They next discuss the problems with using BOD data to directly guide priorities. They stress that BOD data are about problems, while priority setting is about solutions, and describe how priority setting based on BOD fails to capture cost-effectiveness and fairness in the distribution of benefits. Against this background, the authors argue that BOD can play many important roles in priority setting, but that these are all indirect. They outline multiple indirect roles, with illustrations from a recent priority setting proposal in Norway. They conclude with general recommendations for how BOD-related data can be made more useful for priority setting.


The reactions of [(μ-H)3 Re3 (CO)11 (NCMe)] with Sc2 @C82 -C3v (8), Sc2 C2 @C80 -C2v (5), Sc2 O@C82 -Cs (6), C86 -C2 (17), and C86 -Cs (16) have been carried out to produce face-capping cluster complexes. The Re3 triangles are found to bind to the sumanene-type hexagons on the fullerene surface regiospecifically. In contrast, Sc3 N@C78 -D3h (5) and Sc3 N@C80 -Ih show no reactivity toward [(μ-H)3 Re3 (CO)11 (NCMe)], probably due to electronic and steric factors. These complexes can be easily purified by using HPLC. Carbonylation of each complex releases the corresponding higher fullerene or endohedral metallofullerene in pure form. Remarkably, the C86 -C2 (17) and C86 -Cs (16) isomers were successively separated through Re3 cluster complexation/decomplexation. This unique bonding feature may provide an attractive general strategy to purify as yet unresolved fullerene mixtures.


With the development of market economy,consumers put forward higher requirements about power quality and supply reliability.Since distribution transformer is the most important electric power equipment in the distribution network,whose degree of automation will directly reflect the level of the distribution automation.This paper introduces a new multifunction transformer terminal unit based on a MSP430F5438,which is a 16 bit low power consumption flash type microcontroller and an Ethernet chip W5100.This terminal uses the technique of the Ethernet communication to realize remote data transmission and monitor the distribution network parameter and status.This paper also emphasizes on the hardware components,software flow,data collection of this terminal and the methods of Ethernet communication which makes it easier to operate the terminal via Ethernet communication.


Our PhD research is concerned with the task of achieving cooperation in a system of competitive agents which cannot be explicitly controlled. To this end, it examines the problem from the system's point of view, without restricting the agents' behavior or requiring specific knowledge about their decision-making.
The governance of the MAS will be achieved via a dynamically adaptive governing policy based on a set of rules, which leaves full autonomy to the individual agents, but reacts to their actions via
suitable changes of the environment. The mechanism is designed to lead to system-level cooperation while only assuming that the agents follow their own self-interested motives.


The aid effectiveness literature (AEL) consists of empirical macro studies of the effects of development aid. By the end of 2004, it had reached 97 econometric studies of three families, which have been analyzed in one study for each family using meta-analysis. The AEL is an ideal subject for meta-analysis as it uses only a few formally similar models which try to catch precisely the same effects. Also, it is an area with strong beliefs – often generated by altruism – and interests. In this survey of the AEL, we show that when the whole of the literature is examined, a clear pattern emerges in the results: after 40 years of development aid, the evidence indicates that aid has not been effective. We show that the distribution of results is significantly asymmetrical in a way that reflects the reluctance of the research community to publish negative results. The Dutch Disease effect of aid has been ignored but is a plausible explanation for aid ineffectiveness.


By sampling the data in 2001,2002 and 2003 that the listed companies conducted control power to turn to let in three years,share ownership under the condition that listed companies control the power agreement and let medium shell procure a problem.The research indicates that there exist a great deal of shell purchase cases,even up to 40%,in which ST is the main object of shell procurement.The essence of shell purchase does not mean one company procures the other,but rather a way to market stipulation.Their existence reflects the deficiency and problem in legal person′s turnover agreement and the rules of getting listed.This may cause a capital market to choose excellent function and operation efficiency to some extent.Along with perfected market rules the furthered stock right reform and the transparent transaction rules,such cases will be gradually reduced.


Random breath testing (RBT) is one of the most successful drink driving countermeasures employed by police in Australia. Its success over the years has been evidenced by reductions in drink driving behaviour, reductions in alcohol-related crashes and fatal crashes and a corresponding community-wide increase in the disapproval of drink driving. Although a great deal of research has been able to highlight the relationship between increased police enforcement and road safety benefits, little is known about the organisational factors that assist or hinder the management and operation of RBT. The purpose of this thesis is to explore the perceived barriers and facilitators to the effective operation of RBT in the Queensland Police Service (QPS). Findings will have human resource implications for the QPS and will highlight areas that are currently functioning effectively.-----

Study One involved 22 semi-structured interviews with 36 QPS managers involved in the day-to-day organisation and delivery of RBT operations. Managers were recruited with assistance from members of the QPS's State Traffic Support Branch. The interviews were approximately one hour long and involved exploration of the perceptions of managers involved in the planning and delivery of RBT operations using the concept of organisational alignment to structure the interviews. The results revealed that RBT management activity is facilitated by a range of factors, including: the belief in the importance of RBT; belief that the purpose of RBT has both a deterrent function and a detection function; the increasing use of intelligence to guide RBT strategies; the increasing use of RBT to support other crime reduction strategies; and a genuine desire to improve the current state of affairs. However, a number of apparent barriers to the effective operation of RBT were identified. These included concern about the strategy of the 1.1 testing strategy (i.e. conducting the equivalent of one test per licensed driver per annum), a misunderstanding of the role of general and specific deterrence and a lack of feedback in relation to the success of RBT.-----

The second study involved a questionnaire that was distributed to a random sample of 950 operational police stratified across the regions who are responsible for undertaking RBT on a regular basis. There were 421 questionnaires returned representing a response rate of 44%. Questionnaires were also based on the concepts and constructs of organisational alignment and explored perceptions, beliefs and self- reported behaviour of officers. The results revealed that facilitating factors included a belief in QPS ownership of the RBT program, the agreement that the RBT vision includes road safety goals and apprehension goals, and overall motivation, support and belief in their capability to carry out RBT duties. Barriers included perceived strain related to the 1:1 testing strategy, the lack of feedback in relation to the success of RBT, misunderstanding about the role of deterrence and lack of rewards for participating in RBT duties.-----

The results of both studies have implications for the planning and operation of RBT in the QPS. While the findings revealed that there were many aspects of the RBT program that were currently aligned with best practice guidelines, there are areas of misalignment. In particular, the main areas of misalignment included concern about the strain caused by the current 1:1 testing strategy, a lack of feedback about the success of RBT and a lack of education of the nature and role of deterrence in road safety and RBT operations in particular.

This article describes a pilot screening program to detect Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (Ng) sexually transmitted infections (STIs) in adolescent and adult males newly incarcerated in New York City jails using urine-based nucleic acid amplification technology (NAAT). Between December 8 and 22, 2003, 2,417 males were tested; 162 (6.7%) were found positive for Ct and/or Ng STIs, with 138 (86.8%) exhibiting no STI signs or symptoms and 102 (63%) treated prior to jail release. Younger age, positive urine leukocyte esterase test, and ≥11 recent sex partners were predictors of STI. Urine-based screening and treatment was feasible in this setting and identified STI that would otherwise have been undetected. Jails may thus be important venues for targeted male STI screening.


For many years pathologists have teen interested in a peculiar type of pneumonia that frequently complicates certain epidemic diseases, termed interstitial bronchopneumonia because of the cellular infiltration in the walls of the bronchioles and alveoli, and commonly seen in epidemic influenza, measles and pertussis. Dr. Muckenfuss and I 1 have been impressed by the similarity of the pneumonia produced by vaccine virus in the rabbit's lung to human interstitial pneumonia. We, therefore, suspected that a virus might be concerned with human interstitial pneumonia in measles, influenza and whooping cough. Measles is a virus disease, and many investigators now believe that the primary etiological agent of epidemic influenza may also be a virus. On the other hand, the Bordet-Gengou bacillus is almost universally regarded as the etiological agent of pertussis; although a critical study of the relation of this bacterium to the disease reveals many discrepancies. (Löwenthal and St. Zurukzoglu. 2 ) Furthermore, a vaccine prepared from the bacillus is of doubtful value both as a prophylactic and as a curative agent. Pertussis sometimes is complicated by encephalitis, as are the known virus diseases such as measles and vaccinia. Finally, the interstitial character of the pneumonia associated with pertussis is similar to that seen in other virus diseases and therefore suggests the possibility of a virus in pertussis also. Since inclusion bodies are associated with many virus diseases, we examined the sections from 35 cases of pertussis and found intranuclear inclusions in the lungs of 12. These were found in the cells lining the alveoli as well as in the bronchial epithelium. The cells containing the inclusions were always larger than their neighbors and their cytoplasm more basophilic. In a few cases, they were found in liver cells about areas of necrosis and, under the same circumstances, in cells of the adrenal.


AbstractGallic acid is a secondary metabolite compound found in several natural products and has several cytotoxic activities against some cell lines such as breast, colon, prostate, and cervical cancer. This research was aimed to study the stability, affinity, and interaction of gallic acid compounds and their derivatives as well as comparative ligand against androgen receptor through a computational approach, namely in silico molecular docking. The research was conducted in four stages, namely the preparation and optimization of ligand compounds and androgen receptor macromolecules, docking simulation process, and analysis and visualization of simulation results. Computational studies show that gallic acid derivatives provide better inhibitory activity than gallic acid and comparative ligand with an average ΔG value of -7,34 kcal/mol. Compound 3,4,5 tri-methoxy-phenyl-ethyl gallate had the best binding energy value of 8.20 kcal/mol. This was demonstrated by stability, affinity, and strong interactions towards active site amino acids at the androgen receptor. Besides, the formed hydrogen bond was strong enough with an average distance of <3.5 Ǻ which might lead to inhibition and apoptosis through activation of caspase 3 and 9 in prostate cancer cells. Thus, gallic acid derivatives have the potential as inhibitors of androgen receptors and become candidates for new drugs in prostate cancer.Keywords: computational studies, molecular docking, gallic acid and its derivatives, androgen receptor, prostate cancer

We discuss the effect of radiation on unsteady MHD free connective flow through a porous medium in a vertical channel .The unsteadiness in the flow is due to the traveling thermal wave imposed on the wall y = L . A uniform magnetic field of strength Ho is applied normal to the boundaries. The coupled equations governing the flow and heat transfer have been solved by using a perturbation technique with the aspect ratio as perturbation parameter. The expression for the velocity, the temperature, the shear stress and the rate of heat transfer are derived and are analysed for different variations of the governing parameters G,R,M, and 


Rapid urbanization is responsible for the increased vulnerability of land systems and the loss of many crucial ecosystem services. Land systems are typical complex systems comprised of different land use types which interact with each other and respond to external environment processes (such as urbanization), resulting in dynamics in land systems. This work develops a methodology approach by integrating complex networks and disruptive scenarios and applies it to a case study area (Wuhan City in China) to explore the effects of urbanization on land system structural vulnerability. The land system network topologies of Wuhan City during five time periods from 1990 to 2015 are extracted. Our results reveal that the urban land expands at a higher speed than the urban population in Wuhan City; the period of 2005–2010 has witnessed more land area conversions from ecological lands to urban land than other periods; the land system is more vulnerable to intentional attacks on nodes with higher integrated node centrality and larger land area, such as paddy, dryland, and lake; and the network efficiency of the land system would decline sharply if the area shrinkage of paddy, dryland, and lake is larger than 30%, 50%, and 20%, respectively. The results provide some insights into building a resilient urban land system, such as increasing the efficiency of existing urban land and controlling the shrinkage rate of important land use types. This study contributes to existing literature on complex networks by expanding its application in land systems, which highlight the potential of complex networks to capture the complexity, dynamics, heterogeneity, and emergent phenomena in land systems.

 We agree with Ades et al that our study1 was not definitive in ruling out the possibility of intellectual impairment in children born with asymptomatic cytomegalovirus and said as much in our discussion, mentioning the relatively small sample size as one of several caveats. It is important to note that our study included only asymptomatic children with normal hearing in order not to confound the effects of hearing loss on intellectual performance with possible effects of the virus.


The effects of different ratios of female and male on the development of Laminaria female gametophyte were studied. The result shows that the development rates of female gametophyte are similar in the ratios of one to one and two to one. The development rates are both over 70% on the twentieth day and the young sporophytes are normal. For ratios of five to one, ten to one and twenty to one, the development rates of female gametophyte are lower. There are some unfertilized eggs and some young sporophytes are abnormal in these three groups. With the increasing of ratio of female and male, the number of unfertilized eggs is larger.

WinXSPRO is an interactive WindowsTM software package designed to analyze stream channel cross section data for geometric, hydraulic, and sediment transport parameters. WinXSPRO was specifically developed for use in high-gradient streams (gradient > 0.01) and supports four alternative resistance equations for computing boundary roughness and resistance to flow. Cross section input data may be from standard cross section surveys using a rod and level or sag-tape procedures. WinXSPRO allows the user to subdivide the channel cross section into multiple sub-sections and has the ability to vary watersurface slopes with discharge to reflect natural conditions. Analysis options include developing stagedischarge relationships, evaluating changes in channel cross-sectional area, and computing sediment transport rates. Resource specialists can use the estimated stream-channel geometry cross section hydraulic characteristics and sediment transport output to assist with channel design and monitoring, instream flow analysis, the restoration of riparian areas, and the placement of instream structures.


To the Editor: We read with interest the recently published study by Katodritou et al. [1], which addresses the important issue of whether Erythropoiesis-stimulating agents (ESAs) impact survival in multiple myeloma patients. However, it is impossible to draw meaningful conclusions from this retrospective study because of important limitations in both its methodology and reporting. In general, the well-known drawbacks inherent in nonrandomized studies rarely allow such studies to provide a valid estimate for the efficacy of a treatment [2], which is especially true in a setting where the indications for treatment are also strong predictors of outcome. The ESA and none ESA treated populations differed in almost all important prognostic factors. Patients started on ESAs presented with higher age; higher International staging system (ISS) stage; lower platelet count, hemoglobin levels, and serum albumin; and higher serum creatinine, Lactatdehydrogenase (LDH), and b2microglobin. They had more frequent light chain paraproteinemia and achieved a lower response rate to cancer therapy. These discrepancies illustrate that any attempts to compare outcomes between the ESA-treated group and the non-ESA treated group are prone to misleading results and interpretations. Further, the survival curves for both patient groups depart from each other immediately after start of the comparison and continue to depart from each other over the next 50 months of follow up, which is years after initiation and termination of ESA therapy. This clearly demonstrates that the differences observed in this study between ESA-treated and nonESA-treated patients are the result of the selection of two patient populations with very different prognostic features and not the consequence of treatment with ESAs. To control the differences between the ESA-treated and non-ESA treated populations it would have required that all possible confounding factors were identified and measured accurately. Although a multivariate analysis was used in this article to control the marked differences between both groups for several prognostic factors, it is likely that marked differences also existed for unmeasured factors. Furthermore, only limited information was given regarding the details of the multivariate analysis. The article reported neither the results for the full model nor the process used to select variables for building the model, which makes it difficult to fully evaluate the quality of the multivariate analysis results. As it is highly likely that patients with the worst prognoses were selected to receive ESAs, the significance of ESA in the multivariate model may only indicate that ESA use is a good surrogate for poorer performing patients. Additional shortcomings are lack of specifications about the initiation of ESA treatment. As ESAs were started in patients with a baseline hemoglobin value ranging from 7.3 g/dl to 11.9 g/dl, obviously, the decision for beginning ESA therapy was left to the discretion of individual physicians, not standardizing for Hb levels, pretreatment, type of myeloma treatment, or age. Further, it is likely that a mix of patients with different phases of disease were analyzed because it is not made clear whether patients analyzed received their ESA treatment during the first or later line of chemotherapy. Information is also missing regarding time to the first dose of ESA, whether ESAs were given concomitantly with chemotherapy and whether the proportions of patients with or without chemotherapy were comparable between both groups. In this study, the median duration of ESA therapy was only 6 weeks (range 4–10 weeks), which is strikingly shorter than that used in any other meaningful study evaluating the effects of ESAs. In spite of this short treatment duration, the authors report an ESA response rate of 68% but do not mention how the response was defined. It is also unclear why the start time for progression-free survival and overall survival differed. Progressionfree survival was defined from start of treatment (assumed to be chemotherapy), although overall survival was defined from diagnosis. Finally, the generalization of the findings from this study is also limited because the data were collected from only one center and were generated over a period of 19 years, during which the patterns of care for multiple myeloma have changed significantly. Finally, if the authors would really believe in their data they would have refrained from arguing that, ''ESAs still maintain their therapeutic value.'' Presently, an impact of ESA use on survival, either positive or negative, cannot be determined on the basis of this article and on a previous report claiming the opposite, namely, a prolongation of survival in ESA-treated patients [3]. A prospective, randomized trial would be the optimal scenario for answering the pertinent question of how ESA use impacts survival in cancer patients. The second-best approach would be a meta-analysis of all previously conducted studies that randomized patients prospectively to an ESA-treated group or to a control group (best supportive care or placebo control). An international group of investigators is currently aiming to accomplish this task.


Purpose To study pathological changes in retina and optic nerve after hypotony made hy transpupillary cyclophotocoagulation.Methods The hypotony model was established by transpupillary cyclophotocoagulation using gonioscopy. The eyes were enucleared 2 weeks,1 and 2 months after the coaqulation respectively.The pathological changes in retina and optic nerve were observed by light microcopy and transmission electron microscopy.Results The structures of the retina and optic nerve were normal with light microscopy.TEM revealed fragmentation of the photoreeeptor between the outer and inner segment,broken membery disc and intracellular vesicles 2 weeks after coagulation.There were many vesicles in retinal ganglion cells(RGCs)and optic nerve axons.The lamellar pattern of the sheath was also loose at that time.Two months after treating, similar but alleviated changes were found.Conclusion Transpupillary cyclophotocoagulation using goniosoopy is effective to establish the hypotny model and the procedure is relatively easy.It is an ideal model for studying hypotony.Hypotony leads to pathological injuries to retina and optic nerve in rabbits and these injuries happen originally in photoreceptor,RGCs and optic nerve axons.The changes are reversible within two months.

Abstract : It is pointed out that the solution of many problems in mechanics and engineering by means of the Laplace transformation is reduced to the problem of determining the inverse function f(t) from its known Laplace transform F(p). For determining f(t), expanded in Fourier series in sines and in cosines, the values of F(p) in the integer points are used. The problem of the convergence of these series and an estimate of the remainder for certain classes of functions are analyzed. As in the majority of applied problems the properties of f(t) are unknown, and only the Laplace transform F(p) is known, the authors try to formulate the convergence conditions and to determine the remainder in terms of F(P). Two theorems are proved establishing conditions which must be imposed upon F(p) so that the above-mentioned Fourier expansions of f(t) in sines and cosines uniformly converge. The asymptotic expressions are derived for their remainders. (Author)


At room temperature and below, a complete poling of polyvinylidene fluoride film can be produced in less than 1 sec by corona charging. Changes in pyroelectric coefficient and infrared spectra which accompany this poling are described. A transformation from α to another form occurs; development of most of the pyroelectric property occurs at an early stage of this transformation.


The bearing strength of carbon fibre/epoxy laminates composite has been investigated with a new failure criteria instead of conventional load. A precise measurement of hole deformation allows to determine the failure load as a clear kink point on the load-displacement curve. The validity of the new failure criteria was evaluated by cyclic load tests. With the new failure criteria, the effect of bolt-hole clearance and the clamping force were re-evaluated. Effect of the gap between the specimen and bush was also investigated. The experiments show more than 0.1 mm clearance for 6.35-mm hole affect for the failure load but not maximum load. The tightening up torque affects both the failure and maximum load up to . The gap between specimen and bush strongly affect the maximum load but not failure load. These results give a design criteria for thickness tolerance for the cases of using collar on the hole. Significant deviation between conventional load and new failure load were found in several conditions.


The work proposed a veterinary healthcare monitoring and location tracking system for cattle. The health monitoring used the heart rate, body temperature, pulse rate and respiratory rate as vital signs which were monitored using ubiquitous sensors. The signals from these sensors were transmitted to an application in a server for processing. The application utilizes Artificial Neural Network for its decision. The system also utilizes a chip embedded in a cow that communicates with GPS to track the location of cattle at any given time. The system was implemented with Java Enterprise Edition 8. Experimental results indicated that the system did well in monitoring the health statues of the cattle. The results compared well with similar works and have the advantage over such works in the area of tracking the location of the cattle. Keywords— Pervasive Model, Veterinarian, Nutritionist.

Objective The present study was conducted on broilers to evaluate the anticoccidial efficacy of galangal (Alpinia galanga) ethanolic extracts against caecal coccidiosis caused by Eimeria tenella in broilers. Materials and methods One hundred 20 days old broilers (Ross 308), mixed sexes, were randomly assigned into 5 treatment groups (n = 20/group) as 1) positive control, 2-4) galangal ethanolic extracts at 25, 50, and 75 mg/kg body weight, respectively, and 5) 25 ppm toltrazuril. Broilers in all groups were orally inoculated with 25,000 sporulated oocysts of E. tenella at 20 days old. The body weight gain and caecal lesion scores parameters were recorded. Results The results showed that galangal ethanolic extract (AEE) was effective against E. tenella infection; especially at concentrations of 50 and 75 mg/kg per day for 3 consecutive days that can significantly (p<0.05) increase average daily gain (ADG) when compared to positive control. The lowest average caecal lesion score was observed in chickens treated with Toltrazuril. Conclusion The study showed that Alpinia galanga extract can improve weight gain and reduce the severity in caecum of broilers infected with E. tenella. Exploring the maximum potential of galangal in medicine and pharmaceutical applications for further research is needed.

We consider models for the release of transmitter in response to nerve impulses, where it is assumed that quanta of transmitter are released from some of n sites, the probability of release from any site being p. It is assumed that the quantal size is either a constant or is distributed as a normal or a gamma variate. Observations on both spontaneous potentials and evoked potentials are used to obtain moment estimated of n and p. Large sample estimates of the standard errors of these estimates are given.


HPLC made it possible to determine the content of substances characterizing the antioxidant activity of buckwheat husk of four varieties: flavonoids in terms of rutin, iron, copper, zinc, manganese. The antioxidant activity of buckwheat husk does not depend on the varietal characteristics of the plant material and the values of the antioxidant activity correlate with the content of rutin. HPLC has been used to determine the levels of vitamins B1, B3, B5 and C in buckwheat husk. To increase the availability of compounds with antioxidant properties, buckwheat husk was subjected to enzymatic hydrolysis with Shapeit Wafer and introduced into the diet of laboratory animals. The experimental data obtained showed that the introduction of buckwheat husk in the diet of laboratory animals had a positive effect on the oxidant-antioxidant state of the organism of the rat, manifested by a decrease in the index serum oxidative stress - the level of malonic dialdehyde and an increase in antioxidants - catalase, vitamins A and E, trace elements compared to with control. The use of the HPLC method made it possible to establish the relationship between the indicators of the antioxidant systems of the component of the food and the laboratory animals. Determination of the most important indicators of the antioxidant activity of a food component or a food ration by HPLC makes it possible to predict the state of the oxidant-antioxidant system of the human body.


Introduction Labour law is unusual among legal disciplines in that its mainstream tradition is critical (Klare 2002). It was conceived originally as an intervention in a mode of production in which, for structural reasons, the worker was in a position of weakness relative to his employer and consequently vulnerable to ill or unfair treatment. The purpose of labour law was widely understood in terms of addressing the imbalance of power in the employment relationship so as to protect and emancipate the vulnerable worker. Early scholars in the field observed that law could achieve this goal in two ways; either directly – by way, for example, of minimum wage, or health and safety legislation – or indirectly, by providing for the collectivization of workers and the collective regulation of workers' terms and conditions of employment. In either case, the desired result of legal intervention was that the freedom of the employer to impose terms unilaterally should be limited and the freedom of the worker correspondingly augmented.


In this video, we illustrate how one of the classical areas of computational geometry has gained in practical relevance, which in turn gives rise to new, fascinating geometric problems. In particular, we demonstrate how the robot platform IRMA3D can produce high-resolution, virtual 3D environments, based on a limited number of laser scans. Computing an optimal set of scans amounts to solving an instance of the Art Gallery Problem (AGP): Place a minimum number of stationary guards in a polygonal region P, such that all points in P are guarded.


We consider three scenarios for the recirculating electron linear accelerator (RLA) of a linac-ring type electron-proton collider based on the LHC (LHeC): (i) a pulsed linac with a final beam energy of 60 GeV ['p-60'], (ii) a higher luminosity configuration with two cw linacs and energy-recovery (ERL) also at 60 GeV ['erl'], and (iii) a high energy option using a pulsed linac with 140-GeV final energy ['p-140']. We discuss parameters, synchrotron radiation, footprints, and performance for the three scenarios.


Some Anatomic-Topographic Features of Common and Right Hepatic Ducts and their Constituents Aim. Anatomic-topographic features of the common duct and ducts of the right functional liver are attributes of the diagnostic-surgical and transplantation liver practice. In connection with this notion, this study has analyzed the intrahepatic schemes of branching of portal vein, hepatic artery and bile ducts on 4casts, and branching of only portal vein and bile ducts on another 9casts, all of which being prepared with the injection-corrosion method. Material and Methods. The material was obtained from post-mortem human specimens of adult individuals of both sexes. Results. The observation of the casts showed a modal and aberrant type of forming of common hepatic duct at the level of the hilum or at the lower extrahepatic level. The right hepatic duct may be absent, may be with a short bifurcation form and rarely with a significant length. Of the sectorial ducts, the trunk of the posterior duct is most commonly longer than that of the anterior one, and rarely equivalent. Usually the anterior duct lies lower and in a more anterior position, except in 1 case of infraportal position of the posterior duct in relation to the anterior branch of the portal vein. Accessory ducts have also been detected and they originated from profound parenchyma, but also supraparenchymal from the subvesical and subcapsular connective tissue. Conclusion. Common hepatic duct has shown modal and aberrant type of forming at the level of the hilum or at a lower extrahepatic level.


Abstract Originally published on "The View from Left Field." The growth of global far right political movements poses a threat to humanity. To defeat these movements, we need to understand their origins and their relationship to capitalist structures of power. Should political leaders like Donald Trump and Jair Bolsonaro be labeled "far right" or "fascist?" In this post, I will defend the use of "neo-fascist" to define both Trump and Bolsonaro, as well as movements closely linked to them, such as the Brexit movement in Britain.


Digital education considerably requires active participation of students in the learning process, the application of self-regulated learning activities for the attainment of successful learning results. The aim of the present study is the investigation of time perspectives as the predictors of online self-regulated learning. In our study 210 Transylvanian students participated, from the Babes-Bolyai University, Faculty of Psychology and Educational Sciences. Students' demographic characteristics were recorded, for the assessment of self-regulation the Self-regulated Online Learning Questionnaire - Revised was applied and time perspectives of students were measured by the Zimbardo Time Perspective Inventory. A correlational, cross-sectional design was used. On the basis of the results of hierarchical regression, in our first model demographic characteristics explained 5% of the variance for the application of self-regulation activities. In our second model, controlling demographic variables, time perspectives explained an additional 33% of the variance for self-regulation. Self-regulated learning strategies are predicted among demographic characteristics by students' gender, age and online learning, while out of time perspectives only future orientation proved to be a significant predictor. Females, older students, participants attending online education and higher future orientation apply to a higher degree the self-regulated learning strategies as males, younger students and participants with lower scores at future orientation.


I describe an adaptive h-reenement method for solving reaction-diiusion systems in three space dimensions on hexahedral grids. These grids typically have irregular (hanging) nodes. Solutions are calculated using Galerkin's method with a piecewise trilinear basis in space and a BDF code in time. New a posteriori error indicators based on interpolation error estimates for irregular grids are used to control reenement and coarsening. Computational results demonstrate the eeectiveness of the adaptive method on reaction-diiusion equations.


Geographical imaginations of the state-owned agricultural landscape mediated by state-sanctioned neoliberal visual discourse obscures the actual realities of these state-spaces. In this paper, I argue that maps that emerge from everyday practices of subaltern groups not only unveil actual realities of state-spaces but also embed possibilities of these landscapes. Farm-settlers on alienated government farmlands of Oyo State of Nigeria use a participatory sketch mapping to reveal spatialities that contest the authoritative cartographies of the farm settlement scheme. Regardless of the authoritative visualisations of state imaginaries, subaltern mappings are an integral part of the everyday geographies of the state-owned agricultural landscape. In conclusion, social mapping of the economic landscape served not only to counter disinformation but also as visual reminders for improvement evident in the farmers' imagined futures.


Monty Python's Flying Circus had a "cat detector van" so, in this tutorial, we use Python and OpenCV to make our very own cat detector and recognizer. We also cover examples of human face detection and recognition. More generally, we cover a methodology that applies to training a detector (based on Haar cascades) for any class of object and a recognizer (based on LBPH, Fisherfaces, or Eigenfaces) for any unique objects. We build a small GUI app that enables an LBPH-based recognizer to learn new objects interactively in real time. Although this tutorial uses Python, the project could be ported to Android and iOS using OpenCV's Java and C++ bindings. Attendees will gain experience in using OpenCV to detect and recognize visual subjects, especially human and animal faces. GUI development will also be emphasized. Attendees will be guided toward additional information in books and online. There is no formal evaluation of attendees' work but attendees are invited to demonstrate their work and discuss the results they have achieved during the session by using different detectors and recognizers and different parameters.

In order to estimate the ductile crack growth in metallic materials, a potential node release technique is proposed in finite element simulation by introducing a potential node release law in traditional node release technique. J-integral far from crack tip is taken as a fracture parameter and the criterion of node releasing is a crack driving force relating with ultimate fracture strain and stress triaxiality near crack tip. The ductile crack growth and affecting factors are investigated numerically for three-point bend specimen.

The article analyzes the key trends in consolidation and restructuring defense sector assets developed in the XXI century, i.e. the creation of vertically integrated structures in accordance with the decrees of the President of the Russian Federation; the inclusion of financially disadvantaged enterprises in concerns and state corporations, their subsequent financial recovery within the framework of integrated structures; the specifics of integration strategies of the leading defense industry holdings by the example of Rostec group, Almaz-Antey concern, USC group, and Roscosmos group. The paper gives the motives of the Russian defense companies for non-organic growth strategies and restructuring according to the state priorities. The article proposes the approaches to financial recovery of defense enterprises, given the preparation of profound amendments to the bankruptcy law; maintaining a favorable institutional climate in the M&A market for defense enterprises, etc. According to the authors, dominant leaders will continue to participate in the implementation of state programs that will require certain concentration of both efforts and capital as well as assets redistribution of a particular state Corporation.


The size and shape of diffraction spots produced by monochromatized synchrotron X-radiation from a singly bent triangular monochromator are derived following a simpler more comparative treatment given in earlier work on reflecting range and prediction of partiality for oscillation camera data [Greenhough & Helliwell (1982). J. Appl. Cryst. 15, 493-508]. In that treatment the possibility of a polychromatic experiment {[see Arndt Nucl. lnstrum. Methods (1978), 152, 307-311] for an earlier suggestion} was identified and here the energy profile within each diffraction spot is derived along with the spectral resolution ~E/E at any point in the profile due to experimental conditions and sample characteristics. A firm theoretical basis is established so that experimental problems and procedures can be discussed with a view to optimizing the method in the light of the presentation of the first reported polychromatic experiment [Arndt, Greenhough, Helliwell, Howard, Rule & Thompson (1982). Nature (London), 298, 835--838].

The multi-resolution time-domain (MRTD) algorithm represents the spatial variation of electromagnetic fields in a wavelet basis, yielding a time-domain algorithm with considerable advantages vis-à-vis traditional algorithms such as the finite-difference time-domain (FDTD). In a multi-resolution framework basis functions are added locally, to account for increased detail. However, algorithm complexity increases significantly by adding wavelet levels. As an alternative approach, we model the time-domain fields using scaling functions alone, with the scaling-function complexity tied to the associated spatial complexity of the wave problem. Specifically, in regions for which detail is required, small scaling functions are employed, yielding increased spatial sampling. In regions for which a coarse representation is adequate, large scaling functions are employed. The key to this hybrid framework is development of a rigorous procedure for connecting between two distinct scaling-function representations, with that being the subject of this paper. A mathematically rigorous procedure is developed, and several example numerical results are presented. MULTI-RESOLUTION TIME-DOMAIN The multi-resolution time-domain (MRTD) algorithm expands the electromagnetic fields in terms of a wavelet basis, with significant recent interest in the Daubechies orthornormal [1] and Cohen-Daubechies-Feauveau [2] orthonormal basis. In this previous research a wavelet family is selected for characterization of the spatial variation of the electromagnetic fields. Scaling functions are used throughout the domain to characterize the coarse-scale wave phenomena and wavelets are added locally to account for detailed phenomena at particular regions of the domain (where increased wave complexity exists). Using scaling functions alone, the MRTD is a relatively simple extension of the widely used finite-difference time-domain, while accounting for the addition of local wavelets adds complexity. Therefore, as an alternative procedure, we here consider using different scaling functions over distinct portions of a scattering environment, with fine-scale scaling functions employed in regions of detailed wave phenomena and coarse-scale scaling functions employed in regions of simpler wave phenomena. The mathematical challenge involves development of a procedure to connect the scaling functions across these two domains. To do this we borrow ideas from the signal processing and mathematics communities [3]. In particular, in the time-frequency analysis of waveforms in signal processing, it is often desirable to effect a non-uniform time-frequency tiling [3]. Therefore, it is desirable to characterize one portion of the waveform with a particular wavelet family, while employing a different wavelet family over a distinct portion of the signal. Relatively simple linear analysis may be employed to develop localized basis functions that only exist x Distance (m) Ti m e (n s) Current Source


MEETING BRIEFSSEATTLE-- Nearly 5000 scientists flocked here earlier this month for the Society of Toxicology's largest ever annual meeting. While the elements outside were cool and rainy, the elements indoors were hot: One presentation suggested that mercury exposure might increase malaria risk, and a symposium offered new insights into an old enigma of how arsenic causes cancer.


Photoluminescence properties were improved in CaTiO3:Pr3+ phosphor by substitution of Ba and Sr for Ca to a large extent of Ba (0–20%) and Sr (0–45%) fractions. Red emission intensity at 612 nm was greatly enhanced. It achieved its largest value in Ca0.7Sr0.3TiO3:Pr3+ sample, higher by 192% than CaTiO3:Pr3+. Enhancement of red emission in Ba and Sr added CaTiO3:Pr3+ is inferred to originate from improvement of Pr3+ 4f5d capture probability to electrons in the host conduction band and charge transfer state, which are lowered by Ba and Sr addition.


It is not easy to give an accurate definition of engineering. One of the principal questions in defi ning engineering is whether this discipline has it is ow n methodology, or the methodology of engineering is f ully derived from the methodology of pure science. Scientific knowledge is, undoubtedly, extensively used in engineering, but it is also an arguable point that engineering knowledge is not limited by the knowledge base of pure sciences. Engineering often uses appro aches that are practical but not sufficiently rigorous or well- established from a scientific point of view. Invent iveness is an important part of engineering tradition that is difficult to define in precise terms, but its prese nce is one of the cornerstones of the engineering profession. The differences in the methodologies of engineering and pure science are reflected in the realities of engineeri ng education. Although future engineers must be well- educated people and should be taught science and economics, the style of education of scientists and engineers does not have to be the same. The methodology of science is the most established and validated to ol available to modern researchers and, of course, can not be replaced by the methodology of engineering. This, however, does not mean that engineering methodology has no merits of its own. We advocate an inclusive approach to the engineering discipline and relate i ts future success to the ability of educational instit utions to produce broadly-educated specialists.


Liquid-liquid demixing, following spinodal quenches of poly-2-chlorostyrene/polystyrene blends, was followed by light scattering at 632.8 nm. The dependences of demixing on H/D substitution and molecular weight of the polystyrene, and on pressure, are reported. In the region of interest, the phase diagram is of the lower critical solution (LCS) type, and demixing is induced by raising the temperature. The transition temperature is lowered by deuterium substitution. At constant quench depth the transition proceeds more rapidly at elevated pressure. © 1995 John Wiley & Sons, Inc.

This paper presents a novel hybrid framework, Software Requirement Ontologies based Test Case Generation (ReqOntoTestGen) to increase the confidence in the reliability of existing verification and validation (V&V) techniques. This framework integrates the benefits of ontology modelling with the test case generation approaches based on use case-based requirement specifications. ROO (Rabbit to OWL Ontologies Authoring) tool is used in this work to eliminate the ambiguous requirement in natural language by using Controlled Natural Language (CNL). The ontology result from this tool, then, is translated into OWL before this OWL model is mapped into the XML file of data dictionary. Test cases are generated from this XML file by using Combination of Equivalence and Classification Tree Method (CCTM). This testing technique enables the redundant test cases to be eliminated and the coverage of testing to be increased. The contribution of this work has been explored by using the real case study. The result shows how the requirement ontology enhances the testing technique as we expected.


No necessary and sufficient condition for reachability of switched linear singular systems has been found, exceptuating the case of the so-called "equisingular systems". Such a condition is not valid in the general case, as examples show.


Erwinia psidii causes bacterial blight of guava ( Psidium guajava ), an important disease of this crop in Brazil. The pathogen affects branches and twigs of guava trees, reducing yield significantly. Bacterial dissemination often occurs through contaminated but asymptomatic propagating plant material. The objectives of this research were to evaluate the use of BIO-PCR and conventional PCR to detect E. psidii in inoculated guava plants grown in a greenhouse and in symptomatic and asymptomatic trees from guava orchards. Erwinia psidii strain IBSBF 1576 was inoculated (107CFU mL-1) into young guava shoots and plant tissue was analysed at 0, 5, 10, and 15 days after inoculation. Symptoms were observed after 5 days and all inoculated shoots were PCR positive at all times, by both BIO-PCR and conventional PCR. Under natural infection conditions, 40 samples were tested by BIO-PCR from each of three guava orchards, 20 showing symptoms and 20 asymptomatic. PCR was positive for 58 out of 60 symptomatic samples (96.7%) and for 6.7% of asymptomatic samples, showing that the method can be used to detect the pathogen at early stages of infection. This PCR method may be used as a diagnostic tool to assess bacterial survival, dissemination and disease outbreaks.


The title compound, C12H9N3O2, was obtained as a cyclized oxadiazole derivative from substituted thiosemicarbazide in the presence of manganese(II) acetate. The furan ring is disordered over two orientations, with occupancies of 0.76 (2) and 0.24 (2). The dihedral angles between the central oxadiazole ring and the pendant phenyl ring and furan ring (major disorder component) are 3.34 (18) and 5.7 (6)°, respectively. A short intramolecular C—H⋯O contact generates an S(6) ring. In the crystal, inversion dimers linked by pairs of N—H⋯N hydrogen bonds generate R 2 2[8] loops. The dimers are linked by C—H⋯π and π–π interactions [range of centroid–centroid distances = 3.291 (2)–3.460 (8) Å], generating a three-dimensional network.


The anthelmintic potential of methanol and aqueous extracts of G. senegalensis in vitro against the egg hatch and larval development of C. elegans Bristol N2 (susceptible to ivermectin) and C. elegans DA1316 (ivermectin resistant strain) was evaluated.. The eggs and larvae were incubated in aqueous and methanol extracts of the stem bark of G. senegalensis with the serial concentrations of 0.2, 0.4, 0.6, 0.8, 1.0 and 2.0 mg/ml. Methanol extracts of G. senegalensis which inhibited above 80% egg hatch in both strains of C. elegans were moderately effective whereas the aqueous extracts were ineffective. Both aqueous and methanol extracts which recorded up to 90% inhibition of larval development against C. elegans DA1316, as well as C. elegans Bristol N2, were considered effective. However, methanol extract proved more efficient than the aqueous extract against larval development as well as egg hatch in both strains of C. elegans (P 0.05). Therefore, extract from G. senegalensis can be use against ivermectin resistant parasitic nematodes. Guiera senegalensis may be used as a natural source of lead compounds to produce anthelmintic drugs. Cytotoxicity test should be conducted before the extracts are tested in vivo on the infected ruminant animals.

Objective To evaluate the clinical effects of smoking on the response to non-surgical periodontal therapy.MethodsNine male current smokers and 11 male non-smokers with moderate gingival overgrowth induced by the taking calcium channel blockers were chosen for study.Clinical parameters including plaque indexes(PLI),probing depth(PD),bleeding indexes(BI),attachment loss(AL)and hyperplasia indexes(HI)were measured at deepest sites(PD 5~7 mm)of dentition of drug-induced gingival overgrowth before and one month after non-surgical periodontal therapy.The total 78 target sites from smokers and 80 target sites from non-smokers were involved in this study.ResultsThere was no difference between smokers and non-smokers regarding PLI、BI、PD、AL and HI at baseline.After 1 month of non-surgical periodontal therapy,means of PLI、BI、PD、AL and HI were significantly higher in smokers than those in non-smokers.According to AL and BI,there were no statistical significant between the two groups(P 0.05);but PD、PLI and HI were significantly greater for smokers than that for non-smokers(P 0.05).ConclusionThis study confirms that smoking has negative effect on the host response to non-surgical periodontal therapy.


Large herbivores, particularly in water limited systems, are vulnerable to the impacts of poaching (illegal hunting) and human‐induced climate changes. However, we have little understanding of how these processes can reshape their populations. With some rapidly declining populations there is a need to understand the effects of these stressors on populations of vulnerable large herbivores like the white rhino (Ceratotherium simum simum). We developed age‐structured models for the rhino population in Kruger National Park, home to 49% of South Africa's rhinos. We wanted to determine the relative influence of poaching and climate on the current and future population size and demographics, examine the potential of a dependency effect (the loss of calves from poached females) and quantify the compound effect (loss of future young). Our results indicated that population declines were largely driven by poaching and included a dependency effect. Rainfall had a measurable but smaller influence on rhino populations and had an additive effect; reduced rainfall exacerbated poaching losses. Current poaching levels have resulted in a reduction to the lifetime reproductive output per cow from approximately 6 to 0.7 calves: a compound effect of 5.3 future offspring. Under current levels of poaching, we project a 35% decline in the Kruger rhino population in the next 10 years. However, if poaching intensity is cut in half, we project a doubling of the current population over the same time frame. Overall, our models showed little sensitivity to demographic and environmental parameters, except for adult survival. Our results suggest that maintaining and improving the lifetime reproductive output of rhino cows should thus be the highest management priority and that new management targets should consider both the dependency and compound effects associated with poaching on rhino cows.


Zirconium silicate (ZrSixOy) films have been sputtered by comagnetron-reactive sputtering. The composition of ZrSixOy has been controlled by adjusting the sputtering powers of Si and Zr targets to achieve various effective dielectric constants. The sputtered silicate layers showed low equivalent oxide thickness of 14.5 A with a low leakage of 3.3×10−3 A/cm2 at −1.5 V relative to flat band voltage. The silicate films also exhibited good high-temperature stability and smooth interfacial properties on silicon substrate.


Up to now, the government efforts concerning the waste problem remain unsolved. To deal with, three parties involved, namely, government, society and private sector, should work simultaneously and support each other. What has been done by the local government by means of Environment Office or Local Corporate as the responsibility holder of local environment has not performed optimum results.  On the other hand, the society and private sector as the biggest contributors of concrete waste are potential to be involved in solve this environmental problem. Thus, the waste management will be effective when initiated from its source.

Despite a high death toll, public-health efforts to combat suicide lag far behind those focused on preventing accidents and diseases such as cancer. A US initiative aims to redress the balance. helplessness, perhaps. One large clinical trial that directly addressed suicide and psychiatric disease indicated that the antipsychotic drug clozapine could help to cut suicide rates in people with schizophrenia (L. Alphs et al. Schizophr. Bull. 30, 577–586; 2004). And small trials have hinted that lithium may do the same for those with depression. There are no good animal models for suicide risk at present, so biological investigations will have to rely on work with humans. But much can already be done to reduce suicide numbers, even in the absence of biomarkers. One powerful option, on which the report's strategy for reducing suicides by 20% strongly depends, would be to reduce people's access to means of suicide. Surprisingly, many people intent on suicide abandon their plan if their chosen means is not available. Firearms account for about half of US suicide deaths, and modelling work carried out for the new report shows that almost 10% of all suicides could be prevented by restricting access to guns. In 2010, 735 people in the United States killed themselves with carbon monoxide from car exhausts; the report suggests that 600 of those deaths might have been prevented if car manufactures were required to install a sensor inside the vehicle that turns off the engine when carbon monoxide builds up. The report's 20% target will probably not be achieved in the desired five years, but it opens a useful debate that will help more people to understand that the action of committing suicide needs to be considered in the same way as a disorder — as something that can be addressed, not an unavoidable product of circumstance. ■ S ome 38,000 people killed themselves in the United States in 2010. That's more than were killed in traffic accidents (34,000) or by prostate cancer (29,000), and more than twice the number murdered (16,000). Shocking though that is, many other countries monitored by the Organisation for Economic Cooperation and Development have even higher suicide rates. So why do public-health authorities put less effort into preventing death from suicide than they do death from accidents or diseases such as prostate cancer? One institution that has started to take the matter very seriously is the US army. Since …


The final diagnoses made in 989 patterns consecutively patch tested in 1990 have been reviewed. Among the men, their dermatitis was entirely occupational in 17.9% and partially so in 12.5%. Among the women, it was entirely occupational in 6.4%. and partially so in 9.5%. In both groups, irritants exceeded allergens is the cause, whereas allergens superseded irritants in the patients with a non‐occupational eczema caused or aggravated by external Factors. It seems likely that domestic irritants wore overlooked in patients with a non‐occupational dermatitis

Purpose
Constructing porous wind barriers is one of the most effective approaches to increase the running safety of trains on viaducts in crosswinds. This paper aims to further improve the wind-sheltering performance of the porous wind barriers.

Design/methodology/approach
Improved delayed detached eddy simulations based on the k-ω turbulence model were carried out, and the results were validated with wind tunnel tests. The effects of the hole diameter on the flow characteristics and wind-sheltering performance were studied by comparing the wind barriers with the porosity of 21.6% and the hole diameters of 60 mm–360 mm. The flow characteristics above the windward and leeward tracks were analyzed, and the wind-sheltering performance of the wind barriers was assessed using the wind speed reduction coefficients.

Findings
The hole diameters affected the jet behind the wind barriers and the recirculation region above the tracks. Below the top of the wind barriers, the time-averaged velocity first decreased and then increased with the increase in the hole diameter. The wind barrier with the hole diameter of 120 mm had the best wind-sheltering performance for the windward track, but such barrier might lead to overprotection on the leeward track. The wind-sheltering performance of the wind barriers with the hole diameters of 240 mm and 360 mm was significantly degraded, especially above the windward track.

Originality/value
The effects of the hole diameters on the wake and wind-sheltering performance of the wind barriers were studied, by which the theoretical basis is provided for a better design of the porous wind barrier.


The issue being discussed is the use of traditional songket motifs (a type of hand-woven fabric with complex designs and patterns), where they are only applied on fabric. Motifs seem to have a very close relationship with art creation. Optical art illusion has been utilized as an approach in researching and searching for appropriate songket motifs. Besides, few other principles have also been used and studied such as repetition and arrangement of songket motifs like modular structure, sequential combination and repetition. Through few relevant researches, it is noted that besides the field of textile, songket motifs have a big potential to be expanded into other fields, such as architecture and interior design. As a result, this research will focus on the study and formation of new designs and motifs by using Optical Illusion Art method, mainly in producing new artwork.
