The inefficiency of embryo cryopreservation protocols limits the broad use of in vitro production (IVP) of bovine embryos. The aim of this work was to identify the damage caused by cryopreservation and embryo culture of IVP bovine embryos after thawing by in vitro development before and after cryopreservation. Cumulus–oocyte complexes were in vitro-matured, fertilized, and cocultured on granulosa cells in SOF with amino acids (SOFaa) supplemented with FCS. Expanded blastocysts (n = 600) harvested on Days 7 to 9 were submitted to controlled freezing [controlled group: 10% ethylene glycol (EG) for 10 min and 1.2°C min–1 cryopreservation], quick-freezing [quick group: 10% EG for 10 min, 20% EG + 20% glycerol (Gly) for 30 s], or vitrification [vitrification group: 10% EG for 10 min, 25% EG + 25% Gly for 30 s] protocols. The embryos of the control group were not exposed to cryoprotectant or cryopreservation method, and the hatching rate was evaluated on Day 12 post-insemination. The straws (quick and vitrification groups) were first placed on nitrogen vapor (0.8 cm over the liquid nitrogen) for 2 min and then immersed in liquid nitrogen. Embryos were thawed in air for 10 s followed by a 25°C water bath for 20 s. Embryos were rehydrated in PBS + 0.2% BSA + 0.3 m sucrose and PBS + 0.2% BSA for 3 min each. To evaluate development of frozen–thawed embryos, they were cocultured on granulosa cells in TCM-199 or SOFaa both supplemented with FCS for 4 days. Hatching rate of the control group was 46.1%. Data were analyzed by PROC MIXED model of SAS System for Windows®. For TCM-199, the controlled group hatching rate was 44.65 ± 5.94%, quick group did not hatch, and vitrification group showed hatching rates of 9.4 ± 6.8%. For SOFaa, the controlled group hatching rate was 11.6 ± 3.4%, embryos submitted to the quick group did not hatch, and the vitrification group showed hatching rates of 8.7 ± 4.5%. Values were significant at P < 0.05. The controlled group showed a difference compared with the other groups of cryopreservation in both media (TCM-199 and SOFaa). However, TCM 199 showed high rates of re-expansion and hatching. In conclusion, the culture medium influences embryo development after cryopreservation, and TCM-199 is more appropriate than SOFaa.

general report IntrodUctIon The theoretical framework of the Arab Knowledge Report for the year 2010/2011 is determined through addressing the central concept, which the report aims to highlight and discuss thoroughly. This central concept is represented in 'preparing the young Arab generations for the knowledge society' as an objective and a means to achieve the desired Arab renaissance. This chapter addresses the concept of the knowledge society in relation to the preparation of the young along with a number of significant problematic issues relating to the Arab renaissance and involvement in the knowledge society: cultural development in the Arab region, the inherent contradiction in the knowledge society and knowledge economies, the burning of stages and the change in education systems. The concept of preparing the future generations for tomorrow is related to the concept of building the knowledge society as a whole. in short, most of the starting points, requirements and elements requested in the Arab Knowledge Report for 2009 for the establishment of a knowledge society in the Arab region are revisited: To expand the area of freedom, education reform, consolidate iT infrastructure, and creativity stimulation. To that end, a window should be opened to communicate with ourselves and the world to bridge the knowledge gap which will increase daily and become more difficult to remedy if ignored. There are many terms that describe the enormous changes we are living through today and the entities towards which societies have been moving since the end of the 20th Century and the beginning of the 21st Century. The most important of these include the 'information society', 'network society', 'knowledge economy', and 'knowledge society'. These terms can be used interchangeably, even though each term emphasises some aspects, and excludes others, of the transformational phenomenon we are experiencing (Judith Sachs, in English, 2008). The Arab Human Development Report for 2003 considered that knowledge was a tool to expand the options and abilities of human beings, and it was the main key to achieving comprehensive development. It also defined the knowledge society as one based on the dissemination and production of knowledge, employing it efficiently in all areas of community activity, economy, civil society and politics, as well as in private life where knowledge has increasingly become a powerful engine for economic and social transformations (UNDP, 2003). The UNESCO Report issued in 2005 adopted the concept of the knowledge society and used it in …


Cutaneous manifestations of dermatomyositis are generally grouped as pathognomonic, characteristic, compatible, less common and rare (Table 4). The primary lesion appears as a violaceous, macular erythema with a symmetric distribution. This may progress and become poikilodermatous (atrophic with telangiectasia and pigmentary changes) and indurated (as a result of mucin deposition). Pathognomonic manifestations include Gottron's papules and Gottron's sign (Figure 1). Gottron's papules, violaceous papules overlying the dorsal interphalangeal or metacarpophalangeal areas, elbow or knee joints, occur in approximately 70 percent of patients with dermatomyositis. Gottron's sign is erythematous or violaceous, often atrophic, macules or plaques in the same symmetric distribution D ermatomyositis is an idiopathic disorder that includes an inflammatory myopathy and characteristic skin manifestations; polymyositis includes the inflammatory myopathy without the cutaneous findings. The etiology of dermatomyositis remains unknown; some studies have reported an association with histocompatability antigens, environmental agents (e.g., virus, drugs) and autoimmunity. The average age at diagnosis is 40, and almost twice as many women are affected as men. The average age of onset in juvenile dermatomyositis is between five and 14 years. This subgroup of patients has a better prognosis than adult patients. Modern Dermatomyositis is an idiopathic inflammatory myopathy with characteristic skin manifestations. Although the disorder is rare, with a prevalence of one to 10 cases per million in adults and one to 3.2 cases per million in children, early recognition and treatment are important ways to decrease the morbidity of systemic complications. An association with other connective tissue disorders (overlap syndrome) and malignancy make this diagnosis particularly important to primary care physicians. Patient management includes careful evaluation for underlying malignancy and liberal use of physical therapy, antihistamines, sunscreen and oral corticosteroids. Poor prognostic indicators include poorly responsive disease, delay in diagnosis and the presence of malignancy. The therapeutic goal is to maintain function and prevent or minimize sequelae.

An analytic closed-form solution is presented for the double diffraction at a pair of arbitrarily placed wedges that is suitable to be used in a uniform theory of diffraction (UTD) ray description framework. Here, the particular assumption, present in all the past literature, that the two diffracting edges are coplanar is removed. The doubly diffracted (DD) field at a pair of wedges is constructed via spectral synthesis. Such a procedure provides a double spectral integral representation of the DD field that is asymptotically evaluated by resorting to transition functions, typical in double diffraction problems, that can be expressed in terms of generalized Fresnel integrals. The final expression is arranged in the typical UTD fashion and contains a uniform double diffraction dyadic coefficient. The DD field behavior is analyzed in its transition regions to show how the DD field smoothly compensates for the total field discontinuities occurring at shadow boundaries where a singly diffracted field from a wedge is shadowed by the other wedge. Numerical examples are provided to verify such analysis and to test the accuracy of our UTD ray description against method of moments full wave results.

Language planning refers to a kind of humanly-conscious intervention within certain limits in the process of language selection. It has not only something to do with the language itself, but is far more involved in such issues as the adjustments of the relations among people or between people and society through language problems. The traditional analysis on language planning is mainly based on sociolinguistic theories, which tends to emphasize the basic concepts and categories in this area so that, at the macro level of public policy, neither practical nor reasonable measures have been able to brought up. The economic rational-choice theory and the cost-benefit analytical method, however, can effectively compensate for the weaknesses of the traditional studies of language planning, and greatly enrich the development of language planning. This paper reviews the connotation and denotation of language policies and language planning in details, discusses the significance and feasibility of conducting economic analysis and research on these two issues, and makes a comparison between the traditional sociolinguistic analysis and the new-rising economic analysis on language planning.

Simek, Nicole. Eating Well, Reading Well: Maryse Condé and the Ethics of Interpretation. Amsterdam: Rodopi, 2008. Pp 235. ISBN: 978-90-420-23277. Paperback. €47. Eating Well, Reading Well: Maryse Condé and the Ethics ofInterpretation by Nicole Simek proposes a critical, ethical approach to the creative writings of Maryse Condé while simultaneously refusing the paradigm of literature as moral code. Specifically, the book examines the way in which the global reader responds to and consumes each text while keeping in mind the problematic of exemplarity. One of the greatest strengths of the book is the variety and diversity of the subjects addressed within each chapter. Focusing on four main themes including history and globalization, intertextuality and reader reception, trauma and subjectivity, as well as community and ethics, this beautifully executed and meticulous study provides a detailed analysis of eight of Condé's well-known literary works spanning three decades. Maryse Condé is unique in that she writes from the perspective of the privileged bourgeoisie while other Francophone Caribbean writers tend to represent the socio-political plight of the lower classes. Condé is also exceptional for her refusal to subscribe to the literary movements Négritude, Créolité, Antillanité that have largely defined twentieth-century Francophone Caribbean literature. Furthermore, Condé is known for denouncing the notion that literary works possess the power to change the world. Her literary characters thus, do not typically represent models or archetypes of social excellence.


Autonomous, freely navigating and universal robots will no longer work at fixed predetermined positions and at fixed, predetermined paths in the future, they will be used together with the people in a dynamically changing environment. For this modern mobile robots need additional sensors. Therefore, a movable load sensor (1) for load detection and monitoring of a forklift truck (7) is provided. With the load sensor (1) is the load, the lifting fork (2) and the fork lift truck (7) detects lying ahead environment. The sensor data collected is then analyzed with a computer unit (4). The load sensor (1) is moving simultaneously with the load means (6) mounted movable relative to the mast (5) of the forklift truck (7). In addition, the load sensor relative to above the load means (6) (1) is moved here. This will only be possible to take into account dynamic changes in the environment of the forklift truck (7) during the docking process, even in difficult lighting conditions.


Angle-sensitive pixels are micro-scale devices which capture information about both the intensity and incident angle of the light they see. These pixels acquire a richer description of incident light that conventional intensity-sensitive pixels. We provide a mathematical framework for analyzing the imaging capability of these pixels and demonstrate that they provide a response similar to one component of a 2D Hartley transform in angle, with a distinct frequency and orientation. By using several kinds of different pixels throughout an image sensor, we obtain a full, low-order Hartley transform of local angle, which is mapped to a local, spatial Hartley transform by a conventional camera lens. Based on these principles, we demonstrate a light-field camera using an image sensor composed of angle-sensitive pixels and a conventional camera lens. Single images captured by our camera can be directly used for both computational refocus for enhanced depth of field and depth map generation. The algorithms used for these tasks are simple and take advantage of the transform-based nature of angle-sensitive pixel based image capture.


Can we do institutional analysis without institutional theory? Should we? These provocative questions prompt a reflection on institutional thought, but they also serve as an invitation for scholars in adjacent fields—process scholars among them—to reconsider the boundaries between fields and the benefits of crossing them. Such benefits are evident in the work of the founders of institutional theory, none of who were self-consciously "institutional" as they embarked on their careers. Reviewing their work reveals four keys for doing institutional analysis without institutional theory, and the importance of doing so. It also reveals some of the limits of contemporary institutional theory: The dominance of institutional theory in organizational studies is problematic in the sense that many of the most important insights and developments in institutional theory emerged through cross-fertilization across multiple fields, rather than the narrow cultivation of one.


We report the results of recent experiments on magnetoplasma modes in circular sheets of {sup 4}He{sup +} ions trapped below the surface of superfluid helium at a low temperature. The modes we observe include bulk modes, conventional edge modes, multipole edge modes, and extra satellites of unknown origin. The results are compared with earlier observations of bulk and conventional edge modes. Theories of the modes are reviewed and extended, and a detailed comparison with experiment is carried out. {copyright} {ital 1997} {ital The American Physical Society}


Over the last decades, several methods for selecting the bandwidth have been introduced in kernel regression. They differ quite a bit, and although there already exist more selection methods than for any other regression smoother, one can still observe coming up new ones. Given the need of automatic data‐driven bandwidth selectors for applied statistics, this review is intended to explain and, above all, compare these methods. About 20 different selection methods have been revised, implemented and compared in an extensive simulation study.


Plasma-based x-ray lasers allow single-shot nano-scale imaging and other experiments requiring a large number of photons per pulse to be conducted in compact facilities. However, compact repetitively fired gain-saturated x-ray lasers have been limited to wavelengths above λ=8.85  nm. Here we extend their range to λ=6.85  nm by transient traveling wave excitation of Ni-like Gd ions in a plasma created with an optimized pre-pulse followed by rapid heating with an intense sub-picosecond pump pulse. Isoelectronic scaling also produced strong lasing at 6.67 nm and 6.11 nm in Ni-like Tb and amplification at 6.41 nm and 5.85 nm in Ni-like Dy. This scaling to shorter wavelengths was obtained by progressively increasing the pump pulse grazing incidence angle to access increased plasma densities. We experimentally demonstrate that the optimum grazing incidence angle increases linearly with atomic number from 17 deg for Z=42 (Mo) to 43 deg for Z=66 (Dy). The results will enable applications of sub-7 nm lasers at compact facilities.


Nutrient management is dependent on the collection of soil and plant samples for analytical testing and assessment. The quality of the analytical test are subject to bias and precision of the measurements made by the testing laboratory. Failure to understand lab analyses uncertainty can lead to over confidence in the management recommendation. Test uncertainty varies by soil and plant test methods utilized and by performance capability of the testing laboratory. Generally soil methods that provide the most reliable test data, based on the level of within lab proficiency uncertainty are: pH, EC, nitrate, and potassium. Those with the lease reliability are boron, calcium carbonate and soil organic mater. Generally plant methods are very reliable with total nitrogen and phosphorus the most reliable test methods. Laboratory testing is a dynamic process, relative to chemical reagents, instrumentation, laboratory staff and laboratory sample workload, each of which can contribute to bias and increased uncertainty.

Recent experience in the field has demonstrated that the mechanical properties of the annular sealant are a critical factor in the success of a well. A demanding operational regime of the well such as High Pressure/High Temperature (HP/HT) and well interventions, e.g. pressure testing stimulation, put a strong emphasis on the mechanical design of a candidate sealant


ABSTRACT Regional gravity surveys have been conducted (1) across the margin of the Gulf Coast geosyncline and the buried Ouachita fold belt between Bryan-College Station and Austin, Texas, and (2) over the northwestern Llano uplift, in he Llano--Mason--San Saba--Brady area. These new graviyty data have been incorporated with those previously presented by Barnes et al (1954), Watkins (1961), Almy et al (1961), Watkins and Muehlberger (1962), Muehlberger et al (1963), Gordon (1968), and the Air Force Chart and Information Center to obtain a regional gravity anomaly map of a large portion of central and southeast Texas (Figure 1). Bouguer anomalies range from --25 to +10 milligals over the Llano uplift, and form a regional anomaly that is positive with respect to areas around the periphery of the uplift. Superimposed on this regional gravtiy high are a series of more local positive and negative anomalies of 5 to 20 milligals in amplitude that can be readily correlated with major Precambrian lithologic units (as pointed out by Barnes, Romberg, Muehlberger and their associates at the University of Texas). Most of the ovoid gravity lows are caused by granatic bodies of relatively low density. The gravity highs are caused by dense Packsaddle Schist and by local bodies of dioritic to gabbroic composition. Between the highs and lows, large areas having only a few anomaly closures and gentle gravity gradients tend to coincide with Valley Springs Gneiss. These characteristic anomaly patterns can be used to interpret basment lithology concealed by Paleozoic and Mesozoic sedimentary rocks around the flanks of the uplift. South, east, and northeast of the Llano uplift the gravity map has a much different pattern. It is dominated by huge regional anomalies upon which are superimposed very small local anomalies of one-two milligals, only a few of which appear on the five-milligal map. A great arcuate low of 30-60 milligals coincides with the buried Paleozoic foreland basin and frontal zone of the Ouachita system. Farther to the east and south is the well-known gravity high over the interior metamorphic zone of the buried Ouachita system. Finally, to the east and southeast, over the margin of the Gulf Coast geosyncline, the regional anomalies are broad, low-amplitude highs and lows with gentle gradients. In order to analyze these three regional anomalies it was necessary to attempt to "strip" the gravitational effects of the sedimentary rock sequence above the basement. The procedure was as follows: First, gravitational effects of the thick wedge of Cenozoic and Mesozoic sedimentary rocks in the Gulf Coast geosyncline were calculated for three sets of geologically reasonable density contrasts, --0.1, --0.15, and --0.2 g/cm8. Minimum assumed thicknesses of the sedimentary rock sequence, up to 24,000 feet, were based on extrapolations of regional well data. These three models were used to obtain sets of geologic correction curves for the regional Bouger anomaly values. We believe that the largest average density contrast, --0.2, yields the most nearly correct correction because of the presence of the low-density evaporite sequence in the lower part of the section. Second, gravitational effects of the Paleozoic clastic rocks in the foreland basin and frontal zone of the Ouachita system--between the metamorphosed Ouachita facies and the crystalline rocks of Llano uplift--were calculated for several density contrasts and basin configurations. One model was chosen as best fitting the available geologic and geophysical data. The computed gravitational effects of this model were then applied as a further geologic correction to obtain an anomaly profile that should represent, for the most part, effects of changes in basement properties and crustal thickness or density. Corrected regional Bouger anomaly values increase from about --10 to --20 milligals over the Llano uplift to +25 to +30 milligals over the Gulf Coast geosyncline in the vicinity of Wharton and Ft. Bend Counties. If an average crustal thickness of 40 kilometers is assumed in the Llano region, a decrease in crustal thickness to about 30 kilometers or less, similar to the model proposed by Cram (1962), is required to reproduce the regional gravity anomaly. Comparisons of the total mass in crustal and sedimentary columns in the Llano region and the Gulf Coast geosyncline (near Wharton County) indicate that the columns are of equal mass; hence, these two areas are probably in isostatic equilibrium at present. If this is correct, it seems likely that the former site of the Gulf Coast geosyncline was not in isostatic equilibrium near the end of Paleozoic, and that an excess mass was present. We speculate that Gulfward migration of depocenters during the Mesozoic and Cenozoic took place in response to a mechanism for gradual restoration of regional isostatic equilibrium, possibly by lateral subcrustal flow or by a phase change at the crust-mantle interface.

The experiment was conducted in the farmers' field of the Farming Systems Research and Development (FSRD) site, Rangpur under Tista Meander Floodplain highland soils (AEZ # 3b) for three consecutive Rabi seasons (2002-03 to 2004-05). The potato variety Cardinal was tested with 5 levels of magnesium viz., 0, 5, 10, 15, and 20 kg/ha to observe its effects on potato and to find out the optimum and economic dose of Mg for potato. The three years' results revealed that magnesium had significant effects on tuber yield of potato. Significantly higher tuber yield (32.33, 31.63, and 28.03 t/ha in three successive years) was obtained from 10 kg/ha of Mg. Tuber yield tended to decrease with increasing rate of Mg beyond 10 kg/ha. Tuber yields increased over control by 18 and 31 % when magnesium was applied @ 5 and 10 kg/ha, respectively. Yield response to added Mg was quadratic in nature. The regression with Mg levels indicate that maximum tuber yield (30.32 t/ha) could be obtained at 13 kg/ha of Mg and the economic dose was also 13 kg/ha of Mg. Use efficiency of Mg was 512.25 kg tuber of potato per kg Mg per ha. After optimum level of Mg (13 kg/ha) tuber yield reduced by 3.83 kg for additional use of one kg Mg/ha. Key Words: Potato; tuber yield; magnesium; use efficiency. DOI: 10.3329/bjar.v34i2.5797 Bangladesh J. Agril. Res. 34(2): 255-261, June 2009

 (OH)2) precursor (referred to as pCAM) in a stirred tank reactor, followed by a calcination of the pCAM with a lithium compound at elevated temperatures in a roller hearth kiln.1 Thereby, the physical properties of the resulting CAM powders are significantly affected by those of the associated pCAM.2 Independent of the material composition, the fluidity and filterability of pCAM and CAM powders deteriorates drastically with decreasing particle size, with non-uniformity of the particle size distribution, and with a deviation from a spherical particle shape.3,4 However, a fluent form of the pCAM and CAM powders is imperative for their further processing in tonnage quantities during pCAM and CAM manufacturing to prevent clogging of the powders in the technical equipment. As frequent cleaning and/or pulverization of the materials between process steps is cost-intensive, an economical and efficient manufacturing of pCAM and CAM powders requires a precise control of particle size and sphericity, which in turn requires an in-depth knowledge of the pCAM particle formation mechanism during the precipitation reaction.
 To gain a fundamental mechanistic understanding about the pCAM particle formation mechanism, the development of the secondary particle size and morphology during the semi-batch precipitation of Ni0.8Co0.1Mn0.1(OH)2 at various stirring speeds (between 550 and 1350 rpm) was monitored by light scattering and SEM imaging. The evolution of the volume-based median particle size (d
 50) over the course of the run time (t
 run) at the different stirring speeds is depicted in Figure 1a. The d
 50 of initial particles generated after 5 minutes as well as the d
 50 after 8.75 h depends inversely on the applied stirring speed. After an initial nucleation time, the analysis in Figure 1b shows that the size of the approximatively spherical particles at a given stirring speed (for constant feed flow rates) increases linearly with respect to the third square root of run time/run time to the power of one third (t
 run1/3
 ). Thus, the course of particle growth in each experiment can be divided into two distinct regimes: i) for t
 run1/3
 < 1.0 (stage I in Figure 1b), the particle size remains essentially constant; ii) after this initial phase, for t
 run1/3
 ≥ 1.0 (stage II in Figure 1b), the d
 50 increases perfectly linearly with. It is concluded that during stage I, the seeding phase, an increasing number of particles with a constant size are being generated, since the overall volume of formed solid is increasing. In contrast, in stage II, the growth phase, the continuing precipitation occurs via deposition on already existing particles without any further increase in particle number, reflected by the linear relationship between particle size and t
 run1/3
 .
 In light of these results, it is further demonstrated by SEM imaging that, during the seeding phase (stage I), irregularly shaped secondary particle agglomerates are formed, which in the subsequent growth phase (stage II) increase in size by growth of individual plate-like shaped primary particles. Moreover, it is shown that, at constant process parameters, the degree of turbulence quantified by the average energy input and the Reynolds number, both depending on the stirring speed, governs the initial agglomerate size formed during seeding. This not only dictates the growth rate, thus the final particle size, but also the ability of particles to become spherical over t
 run. Finally, a particle formation mechanism is proposed and compared to mechanisms described in the literature.

A grid tied inverter converts DC voltage into AC voltage, while synchronizing it with the supply line phase and frequency. This paper presents an efficient, robust, and easy-to-implement grid tie mechanism. First, the grid tie mechanism was simulated in software using LabVIEW and Multisim. Then, the whole system was practically implemented on hardware. A prototype hardware was developed to produce AC voltage from solar panels. Phase and frequency of the generated voltage were synchronized with those of a reference sinusoidal signal. The synchronization mechanism was digitally implemented on an FPGA, which also controlled the whole system. We achieved real time frequency matching with an improved Zero Crossing Detection (ZCD) technique. Phase matching was also achieved in real time using a modified Phase Locked Loop (PLL) algorithm, which retains stability while being simpler than the general PLL algorithm. Experiments demonstrated that the proposed grid tied system reliably synchronized the phase and frequency of the voltage generated by the implemented hardware with those of the reference grid voltage.


We report the temperature dependence of the Raman spectra of a gelatine-based composite material doped with single-walled carbon nanotubes (SWNT@gelatin). On decreasing the temperature from 290 to 20 K a significant up-shift of the G-mode and no changes in the radial breathing modes are observed. This behaviour cannot be understood by pure thermal effects. We explain these results in terms of an uniaxial strain of the nanotubes induced by the thermal expansion mismatch between the nanotubes and the surrounding matrix.


This paper presents the problem of modeling poroelastic material on a moving structure. It presents the ambiguity of using estimated or measured surface impedance on a rigid structure as opposed to transfer impedance, which takes into account the movement of the structure to which a porous material is fixed. Biot's model for prediction of surface impedance is presented, and the transfer impedance is defined on the basis of this model. A case where several layers of porous material are fixed to a moving wall is also studied. Finally, it presents the level of agreement with experimental measurements in a coupled fluid–structure problem when an impedance considering a fixed structure and an impedance considering a moving structure are used.


Emittance growth and short beam lifetime due to intra-beam scattering in extremely low emittance storage rings can be mitigated if harmonic RF cavities are used for the purpose of lengthening the longitudinal bunch size. The "flat potential condition" can be achieved with harmonic cavities, lengthening the bunch by a factor of ~5. However, the performance is limited by the transient beam-loading effect in the RF cavities, which is induced by gaps in the ring fill pattern. As a counter-measure of this effect, we have proposed the active compensation techniques by using a single kicker cavity having a bandwidth of several times the revolution frequency. The transient effect can be compensated when the kicker cavity voltage is determined to suppress bunch phase shifts along the train.


Phosphanylidenephosphoranes of the type R−P(PR' 3 ), also known as phospha-Wittig reagents, can be utilized in a variety of bond activation reactions pursuing their phosphinidenoid reactivity. In here, we thoroughly show that a facile PMe 3 for H 2 O exchange gives access to various primary phosphine oxides of the general formula RP(H) 2 O (R = Mes*, Mes Ter, Dip Ter). The molecular structure of Dip TerP(H) 2 O was determined and provided the first picture of such species in the solid state. However, phosphanylidenephosphoranes are described to be highly nucleophilic as well. We show that the attachment of main group Lewis acids such as GaCl 3 and GaI 3 to R−P(PMe 3 ) yielded highly sensitive, yet stable [RP(GaX 3 )PMe 3 ] (R = Mes*, Dip Ter) or [(RPPMe 3 ) 2 GaCl 2 ]GaCl 4 (R = Mes Ter). In contrast to the free phosphanylidenephosphoranes, these species reacted differently with H 2 O which was demonstrated for [(Mes*PPMe 3 )GaI 3 ]. Here the formation of the phosphino-phosphonium cation [Mes*P(H)PMe 3 ] + and different anions was observed with combined NMR spectroscopic and SC-XRD (SC-XRD = single crystal diffraction analysis) studies. This work demonstrates that the ambiphilic character of phosphanylidenephosphoranes can be utilized to manipulate the reactivity of R−P(PMe 3 ) towards water, giving primary phosphine oxides, whereas the Lewis acid adducts [(RPPMe 3 )GaX 3 ] gave phosphino-phosphonium species.

A novel arbitrary waveform power amplifier based on switch-linear hybrid (SLH) technology is proposed in this paper. The proposed amplifier utilizes a source follower to achieve excellent output waveforms quality while a switch-mode tracking power supply is employed to obtain high system efficiency. The steady and dynamic performances of the proposed amplifier optimized by the low system output impedance are analyzed. Experimental results verify the validity of the SLH arbitrary waveform power amplifier.


Sampling arises simultaneously with input and output delays in networked control systems. When the delay is left uncompensated, the sampling period is generally required to be sufficiently small, the delay sufficiently short, and, for nonlinear systems, only semiglobal practical stability is generally achieved. For example, global stabilization of strict-feedforward systems under sampled measurements, sampled-data stabilization of the nonholonomic unicycle with arbitrarily sparse sampling, and sampled-data stabilization of LTI systems over networks with long delays, are open problems. In this paper, we present two general results that address these example problems as special cases. First, we present global asymptotic stabilizers for forward complete systems under arbitrarily long input and output delays, with arbitrarily long sampling periods, and with continuous application of the control input. Second, we consider systems with sampled measurements and with control applied through a zero-order hold, under the assumption that the system is stabilizable under sampled-data feedback for some sampling period, and then construct sampled-data feedback laws that achieve global asymptotic stabilization under arbitrarily long input and measurement delays. All the results employ "nominal" feedback laws designed for the continuous-time systems in the absence of delays, combined with "predictor-based" compensation of delays and the effect of sampling.


This chapter examines the legal position and economic role of slaves in Punic Carthage. First, through an examination of the evidence of Graeco-Roman and Punic sources, it shows that Finley was mistaken to dismiss Carthage as relying on non-slave dependants and that slavery was an important institution at Carthage. Second, this chapter looks at the evidence for large-scale exploitation of slave labour in Carthage's large agricultural hinterland and the scale of slave ownership among the Carthaginian aristocracy. It ends by showing how the Romans drew on the technical expertise of Carthaginian slaveholding agronomists in their own approach to slave-based agriculture in Italy.


The article investigates the ability to appropriately utilize "subject inversion" structures displaying the order VS, S= Focus of new information, in the L2 Italian of a group of adults with different L1s. The production of the relevant structures has been elicited through an experimental technique creating the relevant contextual conditions. The results indicate that VS is not adequately acquired by the investigated subjects. The article also discusses the ability in producing null-subjects in presence of finite verbal morphology, in particular by those L2 subjects whose L1 is a non-null subject language. The comparison of the results in the elicitation of VS and in the production of null-subjects shows a dissociation, with null-subjects available to a larger extent. We discuss the theoretical relevance of these results in the light of the following general issues: the structural mapping of discourse related information, according to the "cartographic" guidelines; the notion of "possible interlanguage"; the dissociation of the properties currently related through the null-subject parameter and the conditions at the interface possibly behind that in L2.


Intent-based networking (IBN) systems have become the de-facto control abstraction to drive self-service, self-healing, and self-optimized capabilities in service delivery processes. Nonetheless, the operation complexity of modern network infrastructures make network practitioners apprehensive towards adoption in production, requiring further evidence for correctness. In this paper, we argue that testing, verification and monitoring should become first-class citizens in reference IBN architecture, in order to improve the detection errors during operations. Towards this goal, we present an extension for an intent architecture that allows IBN system to validate the correctness of network configuration using realistic network emulation. Furthermore, we present an intent use-case that ensure correct operation in hybrid networks.


This key comparison aims to assess the capabilities of the participants to determine the amount-of-substance fraction oxygen in nitrogen. The GAWG has classified this as a track B comparison, due to the unexpected 50 μmol/mol argon mole fraction content of the transfer standards, which effects the achievable performance of some measurement techniques such a GC-TCD. The separation of oxygen and argon is challenging, and not all systems in use are equally well designed for it. As this analytical challenge due to a substantial fraction of argon in the transfer standards became a reality, the Gas Analysis Working Group (GAWG) decided to qualify this key comparison as a regular key comparison and not as a core comparison, which may be used to support calibration and measurement capabilities (CMCs) for oxygen in nitrogen, or for oxygen in nitrogen mixtures containing argon only (see also the section on support to CMCs).

The intercooled gas turbine obtained by adopting an indirect heat exchanger into an existing gas turbine is one of the candidates for developing high-power marine power units. To simplify such a strong coupled nonlinear system reasonably, the feasibility and availability of qualifying equivalent effectiveness as the only parameter to evaluate the intercooler behavior are investigated. Regarding equivalent effectiveness as an additional degree of freedom, the steady state model of a marine intercooled gas turbine is developed and its off-design performance is analyzed. With comprehensive considerations given to various phase missions of ships, operational flexibility, mechanical constraints, and thermal constraints, the operating curve of the intercooled gas turbine is optimized based on graphical method in three-dimensional performance space. The resulting operating curve revealed that the control strategy at the steady state conditions for the intercooled gas turbine should be variable cycle control. The necessity of integration optimization design for gas turbine and intercooler is indicated and the modeling and analysis method developed in this paper should be beneficial to it.


Abstract An experimental study of combustion in a porous medium, with and without a cyclic flow reversal of a mixture through the porous medium, was performed. The thermal structure, in terms of axial temperature distribution, of two systems (with and without cyclic flow reversal of the mixture) is compared so as to elucidate the performance of the two systems. The effect of dominating parameters, i.e. half-period, equivalence ratio and flow velocity of the gas mixture on the axial temperature distribution is reported. It is shown that the transient behavior of the thermal capacity of the porous medium, induced by a cyclic flow reversal of the mixture (CFRC system), plays a vital role in yielding a higher quality combustion flame than without a cyclic flow reversal system (OWFC system). The half period of the cyclic flow reversal of the mixture has a moderate effect on the maximum flame temperature. Equivalence ratio and flow velocity have a similar effect on the thermal structure with respect to an increase in the maximum temperature and in the time averaged exhaust temperature, leading to an increase in heat losses. The minimum heal content of the mixture that would be able to burn in this study by the CFRC system is 140 kJ/kg at a minimum equivalence ratio of Φ = 0.046, a flow velocity of about 0.2 m/s and a half period of 30 s.


Aims In the second half of 2020 patients admitted to Highgate Mental Health Centre had to isolate in their rooms until a negative SARS-CoV-2 test result was obtained. This was stressful for both patients, who were unwell in their mental state, and staff. Swabs for PCR testing were only being collected by junior doctors which meant that out of hours, this responsibility would fall exclusively upon the duty doctor. There were often significant delays to obtain a sample. We decided to train non-medical staff on an old age ward so that the responsibility of collecting samples could be shared with nurses and healthcare assistants. Methods In November 2020 we held one training session with several members of staff from our ward. In the following days we did one to one training sessions with the members of staff who, due to their shifts, were not available for the original training session. We excluded admissions that happened prior to SARS-CoV-2 being mandatory, those where the patient refused to be swabbed, and those patients who were transferred from another institution already with a pre-admission swab. Results There were 37 admissions, of which we included 30 based on the exclusion criteria. 17 admissions occurred prior to training and 13 after the training sessions. Prior to training, it took 1.059 days to obtain a sample and it took 0.846 days after the training sessions. Conclusion Providing a training session to enable nurses and healthcare assistants to take samples for SARS-CoV-2 testing reduced the amount of time between admission and obtaining a swab sample. We therefore shortened the first step of the process that leads to obtaining a negative result and enable a patient to come out of isolation.

This paper presents a new algorithm for medical image sequences segmentation,which converts image segmentation into image registration by combining non-rigid registration technology with prior knowledge about anatomy.Firstly,we select Demons algorithm to register image,adopt optical flow method to compute instantaneous displacement,design a new stop criterion for Demons algorithm and implement it in a pyramid multi-scale framework.Then,the deformation fields obtained from image registration are used to wrap the prior image that has been segmented.So the segmented result is obtained.Repeating this process,the segmented results of the whole image sequence can be achieved.Experimental results demonstrate the new algorithm can rapidly get accurate results with few interventions.


The effect of incorporating graphene quantum dots (GQDs) synthesized by a hydrothermal method in the active layer of organic solar cells was investigated. The doping of GQDs into poly[N-9′′-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7-di-2-thienyl-2′,1′,3′-benzothiadiazole)]:C71-butyric acid methyl ester (PCDTBT:PC71BM) active layer resulted in 21% enhancement in power conversion efficiency. The doped GQDs act as exciton dissociation centres in the PCDTBT:PC71BM system. The improvement can be mainly attributed to the fact that the GQDs provide plenty of exciton dissociation interfaces and improve the charge transport pathway. Moreover, the doping of GQDs also offered a general route to optimize the light absorption of organic photovoltaic devices. Our results indicate that doping of hydrothermally synthesized GQDs offers a facile approach to improve the performance of the polymer solar cells.


Statistical techniques are essential in most areas of science being linear regression one of the most widely used. It is well-known that under fairly conditions linear regression is a powerful statistical tool. Unfortunately, some of these conditions are usually not satisfied in practice and the regression models become ill-posed, which means that the application of traditional estimation methods may lead to non-unique or highly unstable solutions. This work is mainly focused on the maximum entropy estimation of ill-posed models, in particular the estimation of regression models with small samples sizes affected by collinearity and outliers. The research is developed in three directions, namely the estimation of technical efficiency with state-contingent production frontiers, the estimation of the ridge parameter in ridge regression, and some developments in maximum entropy estimation. In the estimation of technical efficiency with state-contingent production frontiers, this work reveals that the maximum entropy estimators outperform the maximum likelihood estimator in most of the cases analyzed, namely in models with few observations in some states of nature and models with a large number of states of nature, which usually represent models affected by collinearity. The maximum entropy estimators are expected to make an important contribution to the increase of empirical work with state-contingent production frontiers. The main challenge in ridge regression is the selection of the ridge parameter. There is a huge number of methods to estimate the ridge parameter and no single method emerges in the literature as the best overall. In this work, a new method to select the ridge parameter in ridge regression is presented. The simulation study reveals that, in the case of regression models with small samples sizes affected by collinearity, the new estimator is probably one of the best ridge parameter estimators available in the literature on ridge regression. Founded on the Shannon entropy, the ordinary least squares estimator and some concepts from quantum electrodynamics, the maximum entropy Leuven estimator overcomes the main weakness of the generalized maximum entropy estimator, avoiding exogenous information that is usually not available. Based on the maximum entropy Leuven estimator, information theory and robust regression, new developments on the theory of maximum entropy estimation are provided in this work. The simulation studies and the empirical applications reveal that the new estimators are a good choice in the estimation of linear regression models with small samples sizes affected by collinearity and outliers. Finally, a contribution to the increase of computational resources on the maximum entropy estimation is also accomplished in this work.


Populations of amphibians are experiencing severe declines worldwide. One group with the most catastrophic declines is the Neotropical genus Atelopus (Anura: Bufonidae). Many species of Atelopus have not been seen for decades and all eight Central American species are considered "Critically Endangered", three of them very likely extinct. Nonetheless, the taxonomy, phylogeny, and biogeographic history of Central American Atelopus are still poorly known. In this study, the phylogenetic relationships among seven of the eight described species in Central America were inferred based on mitochondrial DNA sequences from 103 individuals, including decades-old museum samples and two likely extinct species, plus ten South American species. Among Central American samples, we discovered two candidate species that should be incorporated into conservation programs. Phylogenetic inference revealed a ladderized topology, placing species geographically furthest from South America more nested in the tree. Model-based ancestral area estimation supported either one or two colonization events from South America. Relaxed-clock analysis of divergence times indicated that Atelopus colonized Central America prior to 4 million years ago (Ma), supporting a slightly older than traditional date for the closure of the Isthmus. This study highlights the invaluable role of museum collections in documenting past biodiversity, and these results could guide future conservation efforts. An abstract in Spanish (Resumen) is available as supplementary material.


The clinical use of SU 4885 (2-methyl-1, 2-bis-(3-pyridy1)-1-propane) furnishes a new diagnostic test for the indirect evaluation of ACTH pituitary function, provided the adrenal can be assumed to be normal. An increment of 17-ketosteroids is the final result of the enzymic block artificially produced by administration of SU 4885. This is the normal response in a normal pituitary adrenal axis. On the other hand, if a pituitary lesion exists with anatomic destruction of the pituitary, the increment in ACTH levels following administration of this drug is absent or diminished when compared with that in a normal individual. The urinary excretion of 17-ketosteroids is only slightly elevated or not elevated at all during the test performance. Amenorrhea due to psychogenic or neurogenic factors is frequently associated with laboratory findings indicative of total pituitary insufficiency and is in no way different from those associated with destructive pituitary lesions. The SU 4885 test for pituitary reserve function might serve as a diagnostic aid under these circumstances. Three patients having amenorrhea of undetermined central etiology were given a test for pituitary reserve function using SU 4885. Case reports : (1) Y.K. This patient is a 21-year-old unmarried woman complaining of primary amenorrhea. Since September 1962, she had been treated by hormone (once a week, total 15 times), but she had not menstruated. The family history was noncontributory ; there are 5 brothers and sisters with no history of amenorrhea or menstrual irregularities. As for her past history, she suffered from chicken-pox at the age of 3 years. The physical examination showed a normally developed, rather poorly nourished thin woman weighing 44 Kg, 160 cm, with normal axillary and minimal pubic hair, slight hirsutism of the limbs and no facial acne. The breasts were poorly developed. The pelvic examination showed hypoplastic external genitals. The uterus was :small. The x-ray showed a normal sella. The protein-bound iodine was normal (6.0 mg per dl.). Basal temperature records were monophasic. (2) M.H. This patient is a 34-year-old unmarried woman complaining of primary amenorrhea. The family history was noncontributory in that there are 4 brothers and sisters with no history of amenorrhea or menstrual irregularities. As for her past history, she suffered from idiopathic thrombopenic purpura and was in the hospital under treatment. The physical examination showed a hypoplastic woman weighing 33.7 Kg, 136 cm, with no pubic hair and minimal hair on other parts, and no acne. The breasts were poorly developed. On pelvic examination, the external genitals, vagina and


Data encryption and authentication are essential for secure NVM. However, the introduced security metadata needs to be atomically written back to NVM along with data, so as to provide crash consistency, which unfortunately incurs high overhead. To support fine-grained data protection without compromising the performance, we propose cc-NVM. It firstly proposes an epoch-based mechanism to aggressively cache the security metadata in CPU cache while retaining the consistency of them in NVM. Deferred spreading is also introduced to reduce the calculating overhead for data authentication. Leveraging the hidden ability of data HMACs, we can always recover the consistent but old security metadata to its newest version. Compared to Osiris, a state-of-the-art secure NVM, cc-NVM improves performance by 20.4% on average. When the system crashes, instead of dropping all the data due to malicious attacks, cc-NVM is able to detect and locate the exact tampered data while only incurring extra write traffic by 29.6% on average.


that the perceptions of people on economic issues do matter in deciding whom they vote for. A vote for the incumbent party depends on the well-being of the national economy as well as the individual household. Voting decisions are based on retrospective evaluations of the economic condition. Expectations of the economy in the future did not show a significant effect on voting decisions. While both national and personal considerations have an effect on voting, the latter seem to matter more to Indian voters than the former. An

Future NASA missions are increasingly seeking to use actuators for precision positioning to accuracies of the order of fractions of a nanometer. For this purpose, multilayer piezoelectric stacks are being considered as actuators for driving these precision mechanisms. In this study, sets of commercial PZT stacks were tested in various AC and DC conditions at both nominal and extreme temperatures and voltages. AC signal testing included impedance, capacitance and dielectric loss factor of each actuator as a function of the small-signal driving sinusoidal frequency, and the ambient temperature. DC signal testing includes leakage current and displacement as a function of the applied DC voltage. The applied DC voltage was increased to over eight times the manufacturers' specifications to investigate the correlation between leakage current and breakdown voltage. Resonance characterization as a function of temperature was done over a temperature range of -180°C to +200°C which generally exceeded the manufacturers' specifications. In order to study the lifetime performance of these stacks, five actuators from one manufacturer were driven by a 60volt, 2 kHz sine-wave for ten billion cycles. The tests were performed using a Lab-View controlled automated data acquisition system that monitored the waveform of the stack electrical current and voltage. The measurements included the displacement, impedance, capacitance and leakage current and the analysis of the experimental results will be presented.

The aim of this research is to evaluate the effects of education given through digital resources on the language didactic potential of students with the views of teachers. 40 primary school teachers who teach 1st–4th-grade students in various provinces of Kazakhstan participated in the research. In the research, case study, which is one of the qualitative research methods, was used. The research data were collected through a semi-structured interview form prepared by the researcher in order to get the opinions of the teachers who voluntarily agreed to participate in the research. The research data were analysed by the content analysis technique. As a result of the research, it has been determined that teachers are prone to use technology and partially use digital resources in their lessons. However, teachers stated that they are more open to the use of digital resources if the opportunity is given. In addition, although most of the teachers state that the use of digital resources has no effect on increasing the workload of the teacher, some define it as a workload. With regard to the digital resources used in the course, teachers stated that it partially increased teacher success and that it had a positive effect on student success and student motivation. The research findings reveal that teachers need to receive supportive training on the use of digital resources in education.

BACKGROUND: Cardiovascular system is a very importantorgan that plays a vital role in tissue function. In farm animals,the growth and high milk production depends on function ofcardiovascular system. OBJECTIVES: Cardiovascular health inhigh and low-yielding dairy cows was investigated. METHODS:Fifty 4-year-old high- yielding Holstein dairy cows and fifty 4-year-old low- yielding Holstein dairy cows were used in thisstudy. Electrocardiogram was recorded by a base- apex lead, andblood samples were collected from the jugular vein for themeasurement of cardiac biomarkers (CK (Creatine Kinase), CKMB(Creatine Kinase-Myocardial Band), LDH (LactateDehydrogenase), and AST (Aspartate Aminotransferase) andtroponin I). RESULTS: Cardiac dysrhythmias were detected morein low- yielding Holstein dairy cows (62%) compared to highyieldingHolstein dairy cows (46%). The cardiac dysrhythmiasthat were observed in low- yielding Holstein dairy cows includedsinus arrhythmia (34.7%), wandering pacemaker (22.45%),sinus bradycardia (18.37%), sinus tachycardia (10.20%), atrialpremature beat (2.04%), sinoatrial block (2.04%), atrialfibrillation (8.16%), and atrial tachycardia (2.04%). The cardiacdysrhythmias were observed in high- yielding Holstein dairycows, including sinus arrhythmia (86.95%) and wandering pacemaker (13.05%). Also, notched P wave was observed in highandlow- yielding Holstein dairy cows, 30% and 14%respectively. The amount of cardiac biomarkers in the lowyielding cows was significantly higher than that of the highyielding cows. Further more, there was not any detectablesignificant difference of serum concentration of total CK betweenthe high and low- yielding Holstein cows. CONCLUSIONS:Despite significant differences in cardiac biomarkers and basedon the normal range of cardiac biomarkers in both groups, theincrease in cardiac dysrhythmias in low- yielding Holstein dairycows may be metabolic and electrolyte disorders.


Risk disclosure is an essential element of the marketing of prescription drugs and other medical products. This studyexamineshowconsumersrespondtoverbalinformationaboutthefrequencyandseverityofmedical-product risks and how media-induced affect can moderate such responses. The study finds that consumers tend to overestimate the actual likelihood of adverse events described with words such as "common "or "rare "(compared with the probabilities such terms are typically intended to convey) and that consumers tend to give little weight to such probability language when forming product use intentions. However, consumers in positive media-induced moods seem to engage in more nuanced evaluation of product risk information, weighing both frequency and severity information and using such information to make inferences about other product attributes (e.g., product efficacy). These findings suggest that medical marketers and regulators need to devise more effective means of communicating risk probability to consumers and that positive mood induction (e.g., by placing advertisements in upbeat media environments) can enhance consumers 'ability to process product risk information.

A massive integration of renewable energy sources is imperative to comply with the greenhouse emissions reduction targets fixed to achieve the limitation of global warming. Nevertheless, the present integration levels are still far from the targets. The main reason being the technical barriers arising from their non-manageable features. Photovoltaic and wind sources are the widest spread, as their maturity allows generation with a high-efficiency degree. A deep understanding of facilities' performance and how they can match the energy demand is mandatory to reduce costs and extend the technical limits and facilitate their penetration. In this paper, we present a novel methodology to evaluate how photovoltaic–wind hybrid facilities, placed in an urban environment can give generation patterns which will be able to match the demand profiles better than facilities installed individually. This methodology has been applied to a broad number of locations spread over the whole planet. The results show that with high homogeneity in terms of site weather characteristics, the hybrid facilities improve the matching up to 15% over photovoltaic plants and up to 35% over wind.


Key Points Question Is dabigatran etexilate or dose-adjusted warfarin efficacious and safe to use in preventing the recurrence of venous thrombotic events among patients with cerebral venous thrombosis? Findings In this exploratory randomized, open-label clinical trial of 120 patients with cerebral venous thrombosis, no recurrent venous thrombotic events were observed in patients randomized to either the dabigatran or warfarin treatment group; 1 major bleeding event was recorded among users of dabigatran and 2 among users of warfarin. Meaning This study suggests that both dabigatran and dose-adjusted warfarin may be safe options to prevent recurrent venous thrombotic events in patients with cerebral venous thrombosis.


Objective To evaluate the genetic diversity of 30 Helicobacter pylori isolates from the patients in four cities of China(Beijing,Shanghai,Guangzhou,Chongqing)by the multilocus sequence typing(MLST),and to find the link between the vacA genotype and sequence type(ST).Methods Isolates were randomly recruited from consecutive endoscopy clinics in four cities.An average of 5-6 strains per patient were isolated and eight loci selected for the MLST scheme were amplified and sequenced with primers.The vacA genotype was analyzed by PCR and 3% agarose electrophoresis.Results There were totally 28 ST genotypes,most of which are new ST genotypes that have never been found among the database.The most prevalent vacA genotype was s1a/m2(83.3%),followed by s1b/m2(13.0%).In contrast,the s1a/m1 genotype was scarcely present(0%).Conclusion The vacA genotype varied for each ST.Our results showed no obvious link between STs and vacA genotypes.As there are little data on human isolates due to the absence of systematic epidemiological investigations of H.pylori in medical laboratories,our research will provide useful information in understanding the epidemiology of H.pylori in China.


SUMMARY When predicting the deformation of the Earth under surface loads, most models follow the same methodology, consisting of producing a unit response that is then convolved with the appropriate surface forcing. These models take into account the whole Earth, and are generally spherical, computing a unit response in terms of its spherical harmonic representation through the use of load Love numbers. From these Love numbers, the spatial pattern of the bedrock response to any particular scenario can be obtained. Two diierent methods are discussed here. The ¢rst, which is related to the convolution in the classical sense, appears to be very sensitive to the total number of degrees used when summing these Love numbers in the harmonic series in order to obtain the corresponding Green's function. We will see from the spectral properties of these Love numbers how to compute these series correctly and how consequently to eliminate in practice the sensitivity to the number of degrees (Gibbs Phenomena). The second method relies on a preliminary harmonic decomposition of the load, which reduces the convolution to a simple product within Fourier space. The convergence properties of the resulting Fourier series make this approach less sensitive to any harmonic cut-oi. However, this method can be more or less computationally expensive depending on the loading characteristics. This paper describes these two methods, how to eliminate Gibbs phenomena in the Green's function method, and shows how the load characteristics as well as the available computational resources can be determining factors in selecting one approach.

The influence of apical dominance is widely studied in fruit trees, but works that show the opposite effect are little known. The objective was to evaluate the influence of lateral buds (LB) on the apical bud (AB) on apple twigs. Were sampled twigs, 20-25 cm of cv. Castel Gala in May/2010 and June/2011, in Papanduva-SC. The experiment was conducted at Embrapa Uva e Vinho Bento Gonçalves/RS. The treatments were: i) 2010 I: intact twig; A: removal alternating of 50% LB along the twig; SI: LB lower removal of twig (50%); SS: LB upper removal of twig (50%); SL: removal all LB of twig and SA: removal AB of twig; ii) 2011 I: intact twig; SS: LB upper removal of twig (50%); FSLS: intact twig with injury below the LB upper. The twigs were submitted to 3oC per 168, 336 and 504 chilling hours (CH), in 2010, and 456 CH, in 2011 and later transferred to 25oC, for budburst evaluation. The experimental design was a randomized block with two replications per treatment and 40 twigs per plot. Budburst data were evaluated through maximum budburst, precocity and uniformity. The increase of HF increased the amount of AB sprouted due to overcome dormancy. The LB were strongly affected by apical dominance, regardless of the cold period. The treatments with LB upper presence provided lower percentage of maximum budburst and lower precocity and uniformity of budburst of AB compared to the other treatments. The AB is influenced by LB, especially those located near the extremity upper of twigs.


Abstract The angular distribution of the particles emitted in (d, p) or (d, n) reactions is calculated, assuming a stripping process, by means of the Born approximation. The result resembles in most respects that of more complicated calculations by S. T. Butler, but there are certain differences which are discussed in relation to experiments which have been, or may be done. The particles are emitted mainly at fairly small angles to the incident direction, and the precise shape of the distribution is simply related to changes of angular momentum and parity occurring. The principal unknowns in the formulae are matrix elements, which may be estimated for sufficiently high energies by the statistical method.


In the preemptive case there are several possible deenitions for MAXIS. One natural deenition for MAXIS is to repeat as long as needed the following procedure: color a maximum independent set with one color, then reduce the requirements of all the vertices in the chosen set by one. The following example shows that such an algorithm has an approximation ratio of (p p). Consider two vertices with requirement p that are connected to a clique of size p p in which all vertices have requirement 1. MAXIS colors rst the two special vertices with p colors and then colors in a sequence each vertex in the clique with one color. This yields a multi-chromatic sum of p(2 + p p) + ? p p 2 which is (p p p). On the other hand, the optimal solution schedules the clique vertices rst. This yields a multi-chromatic sum of ? p p 2 + 4p = O(p). Thus, the approximation ratio is (p p). In the co-scheduling variant, the above procedure is the most natural way to generalize MAXIS and the counter example holds also in this model. However, it is not diicult to verify that this algorithm is a minf4p; ng approximation for the co-SMC problem. This turns out to be best possible even for trees. Consider the following graph on n = 2t + 1 vertices, with E = fv i v t+i ; v n v t+i : i = 1; : : :; tg. All vertices have unit color requirement except v n that requires p colors. MAXIS will rst color v n and the rst t vertices, with the second t vertices delayed until color p+1. The cost of this coloring is t(p + 1) + t + p np=2. The optimal solution colors the rst t vertices with color 1, the next t vertices with color 2, and the last vertex with colors 3; : : :; p + 2. The cost of this coloring is 3t + (p + 2) 2(n + p). Hence, the approximation ratio is (min(n; p)). In the non-preemptive case, the algorithm may do still worse. Whenever the set of currently colored vertices becomes a non-maximal independent set, MAXIS in this model would nd the largest set of vertices that the solution can be extended with. Consider the graph G given by three independent sets A, B, C. The edges …


Modern optical partial discharge (PD) detection system based on fiber-optic sensors for PD on-line health monitoring in high-voltage (HV) cable terminations necessarily requires optically transparent or translucent insulation materials. The optically compatible silicone rubbers are the key to facilitate such innovative technology. In this work, AC 50 Hz dielectric strength Eb and mechanical properties of three types of commercially available silicone rubbers have been investigated. The investigations revealed that the translucent silicone rubber has a good mechanical performance but its Eb value is considered too low. However it is sufficiently good for use as base material for rubber stress cones. Unfortunately, its optical transmittance is poor compared to optically clear transparent silicones. On the other hand, the mechanical properties of transparent silicone rubbers do not comply with those demanded from push-on stress cones. In particular, their elongation at break is considered too low for that application. However they provide the Eb values of about 28 kV/mm to 29 kV/mm at 0.5 mm thickness, which are higher than those of the translucent type. Moreover, it was found that the post-curing process does not provide a positive impact on the ultimate elongation of silicone rubbers.


: Based on the curriculum ideology and politics of electronic technology basics for non-electricity majors in Chengdu University of Information Technology, the necessity of developing curriculum ideology and politics and the general idea of curriculum construction are expounded, and the organic integration of professional knowledge and ideological and political elements is discussed in depth. Finally, putting forward a further research plan is to break through the difficulties existing in the current ideological and political construction of the curriculum, and finally realize the fundamental task of "cultivating morality and cultivating people" in colleges and universities. The ideological and political effect of the course is remarkable, which can provide a reference for the teaching exploration of ideological and political courses in other professional courses.

In the 1930s, the Home Owners Loan Corporation (HOLC) graded urban neighborhoods based on their mortgage investment risk, designating whiter wealthier neighborhoods a grade A for "best" and lower-income non-white neighborhoods a grade D for "hazardous." Despite the fact that this process was outlawed by the 1960s, formerly redlined neighborhoods continue to have less access to resources, including food. The central premise of this paper is that historical housing policies have shaped inequitable distribution of food destinations in the contemporary food environment, and may have implications for food system advocacy and policymaking. Using geospatial analysis and multiple linear regressions, this study explores the association between redlining and the densities of a broad range of food destinations across Buffalo, NY. Standard socioeconomic and urban area-level characteristics were used to control for race, education level, income, employment, lone parenthood, vehicle access, income inequality, vacancy, and age of housing. Findings show that HOLC grades had significant positive associations with the density of chain convenience stores, discount stores, snack and nonalcoholic beverage restaurants, and urban agriculture, and significant negative associations with the density of gas stations, even after adjusting for sociodemographic and urban area-level factors. These findings emphasize the longstanding impact that housing policies can have on the contemporary food environment, even decades after they were outlawed. They encourage policymakers and advocates to not only address the impacts of historic policies on current inequities, but also to consider the impact that contemporary policies may have on future generations. Acknowledgements First and foremost, I would like to thank my advisors, Dr. Trace Kershaw and Dr. Yeeli Mui, for supporting me every step of the way. This thesis would not be where it is today without Dr. Kershaw's guidance through the quantitative analysis and scope of the paper, as well as Dr. Mui's expertise on food systems and urban planning. Thank you for your patience and mentorship throughout this process! I am also deeply indebted to my family and friends for the moral and emotional support that was an essential piece of staying focused and staying positive throughout this process. I am grateful for the encouragement and enthusiasm for my project, even when I wasn't feeling it myself! I am also grateful to the people, classes, and organizations that have shaped my passion for equitable food systems: my former team at Urban Harvest STL; the courses "Food Systems: Implications of Unequal Access" and "Social Justice and the Global Food System" at Yale School of the Environment; Latha Swamy and Kimberly Acosta at the City of New Haven's Food System Policy Division; Shannon Whittaker and her research on gentrification; and many more. Finally, this project would not have been possible without Dr. Mui and the Growing Food Policy From the Ground Up project that shaped this project around Buffalo. While I did not end up using data from this project in the end, I am grateful for the opportunity to do adjacent work and have the deepest admiration for everything they do to support a more equitable food system in Buffalo and beyond.


Inhibition of angiotensin‐converting enzyme (ACE) induces anemia in humans and mice, but it is unclear whether ACE is involved in other aspects of hematopoiesis. Here, we systemically evaluated ACE‐knockout (KO) mice and found myelopoietic abnormalities characterized by increased bone marrow myeloblasts and myelocytes, as well as extramedullary myelopoiesis. Peritoneal macrophages from ACE‐KO mice were deficient in the production of effector molecules, such as tumor necrosis factor‐α, interleukin‐12p40, and CD86 when stimulated with lipopolysaccharide and interferon‐γ. ACE‐KO mice were more susceptible to Staphylococcus aureus infection. Further studies using total or fractionated bone marrows revealed that ACE regulates myeloid proliferation, differentiation, and functional maturation via angiotensin II and substance P and through the angiotensin II receptor type 1 and substance P neurokinin 1 receptors. Angiotensin II was correlated with CCAAT‐enhancer‐binding protein‐α up‐regulation during myelopoiesis. Angiotensin II supplementation of ACE‐KO mice rescued macrophage functional maturation. These results demonstrate a previous unrecognized significant role for ACE in myelopoiesis and imply new perspectives for manipulating myeloid cell expansion and maturation.—Lin, C., Datta, V., Okwan‐Duodu, D., Chen, X., Fuchs, S., Alsabeh, R., Billet, S., Bernstein, K.

We review in a systematic way how anomaly free $SU(3)_c\otimes SU(3)_L\otimes U(1)_x$ models without exotic electric charges can be constructed, using as basis closed sets of fermions which includes each one the particles and antiparticles of all the electrically charged fields. Our analysis reproduces not only the known models in the literature, but also shows the existence of several more independent models for one and three families not considered so far. A phenomenological analysis of the new models is done, where the lowest limits at a 95 \% CL on the gauge boson masses are presented.

The author, referring to Christ's words: "I tell you, not seven times, but seventy-seven times" (Matthew 18:22), is attempting to find the answer to the question: "can you order someone to forgive?" and consequently: "whether forgiveness is an act of justice or love". A conclusion to this issue requires a response in several stages. First, the author shows that justice, which demands a punishment of guilt is unknown to forgiveness, which waives the right to a fair punishment. Forgiveness thus appears as a heroic virtue, which is the gift of excess and beyond human justice. Thus, it is both an act of love and an act of mercy. It is a perfect gift offered to the offender, free and irreversible. It does not mean, however, that forgiveness is an enemy of justice. It is not opposed to the dictates of justice, although it does not exhaust them. The "innate" nature of forgiveness, exceeding the requirements of justice and demanding an impartial and freely o ered on the part  of the victim, makes it that it cannot be an order by law. Christ's command to the student: "You should forgive!" may be read symbolically. A situation of broken ties or suffering due to separation, is an urgent call to forgiveness. The victim hears the silent cry of the culprit: "love me!", "forgive me!", "do not kill me because you love me!", "let your love be greater than my sin!", which demands an immediate response in the form of forgiveness.


Jndulhnt Fev-er. M. SAANDON and J. DUPONNOIS (Arch. Soc. des. Sci. MIld., January, 1929, p. 153) report a case of undulant fever of a particularly prolonged and refractory nature, in which cure was obtained by the administration of trypaflavine (gonacrine). The oiset was slow, with a typical undulating temlperature, profuse foul-smenlling sweats, and emaciation. The arthralgias, 'characteristic of the disease, did not dlevelop till two to tour eTou-ths later. At the end of five and a half inonths the patient entered hospital comnplaining of extreme weakness and pains in the lumbar region aud legs, especially the right, which were agggravated by pressure, even of the bedclothes. Erichsen's test elicited pain over the left sacroiliac articulation. There was slight motor deficfiency in the right leg; the right patellar reflex was diminished, but the other reflexes were normal. Radiography revealed a marked separation of the left sacro-iliac articulation, ankylossis of the left condyloid articulations along nearly the wh-ole of the dorso-lu nbar columnn, effaoement of the inervertebral spaocs, anid erosion of the fourth lumbar body. The agglutination test was positive in 1 in 200, though 1B. meelitensis was not isolated from the blood til -about the ninth month. Treatment wvith the specific vaccine, and infra--ed irrndiations, caused only slight improvement. Intravenous injection.s of trypaflavine were then tried (the te1th mionth of the disase) the coifimencing dose being 10 eg., which was progressively increaed by 10 cg. a dose to 50 cg.; these were given at gradually increasing intervals of one, two, and three days.

Introduction Coxa vara is an uncommon orthopaedic condition. Problems associated with the definition, radiological appearance, classification and surgical treatment are discussed. Methods A clinical and radiological review of 11 patients (14 hips) treated with a LCP plate (Synthes) in our paediatric orthopaedic unit from 2010 to 2013 was performed. These hips were classified as congenital (6), developmental (3) and acquired (5). The Hilgenreiner Epiphyseal (HE) angle, the head/shaft angle and the neck/shaft angle were all assessed and examples shown why one measurement does not address every case. Results A mean radiological improvement of 45 degrees (20–75 +/−16.5 degrees) was obtained. There was no loss of position in any of our patients from initial surgery until union. Complications included over-correction (1 case), under-correction (2 cases) and a peri-prosthetic fracture in a patient with Osteogenesis imperfecta. Conclusions Limitations of the LCP system include a demanding surgical technique and, in South Africa at least, a limited plate selection. Advantages include excellent proximal control with precise correction, and in our experience provide the best fixation for valgizing proximal femoral osteotomies in the paediatric coxa vara patient.

Different from traditional method that regards the relationship among working parts in various orders as that of simple ones in series, in the research on reliability assessment of power supply system for a certain type of fighter equipped with cool standby units the authors propose a new Laplace transform based method to calculate both reliable life and mean time to failure of power supply system for a certain type of fighter with different cool standby units. Calculation results show that the proposed method is simple, effective and practicable.

Transgenic tobacco transformed with the Trichoplusia ni granulovirus enhancin gene has been demonstrated to enhance baculovirus infection in larvae. In this paper we describe the effect of the long-term feeding of lyophilized transgenic tobacco material to Pseudaletia separata and Spodoptera exigua larvae. Our results demonstrated that the baculovirus enhancin gene products have potential for use in insect pest management.


out their philosophical bases, and studying their implications for practice. Redefining the two concepts and adopting a totally idiosyncratic terminology serves no useful purpose, and adds to the terminological confusion that has plagued us for so long. Furthermore it puts those who learn from this text in a position where they can only contribute to debate with the rest of the world by abandoning the terminology they have been taught. This was an unfortunate choice and in itself is enough to persuade me not to use the text. At various points in the book, material has been introduced to reflect changed thinking about testing. In Chapter 2, a basic teaching model is described that links instructional objectives, entering behaviour, instructional procedures and performance assessment, and clearly implies a criterion-referenced approach to assessment. Small sections have been added to the chapters on reliability (proposing no alternative) and item analysis (proposing an unrealistic alternative) but, by and large, the philosophy permeating the book is that of norm-referenced measurement. The last paragraph in the chapter on reliability spells this out very clearly:
