Unmanned Aerial Vehicles (UAVs) or otherwise known as Drones define that on-board pilot is replaced by a remote controlled computer system and the radio link. The increasing presence of drone technology and its influence in today's world is quite apparent. UAVs have immeasurable potential in different services where they are becoming eyes and ears and providing a broad range of solutions. Flying opens new opportunities to soar above the horizon and snap a photo or videoand we experience the benefits that they are providing. However, despite the promising potential, one of the main problem is endurance or flight time as it uses limited energy storage batteries or conventional fuel which has a limited life and is costly. Using solar energy through solar cells into modern aircraft technology instead of increasing the size of the fuel system or battery sizing will increasing the potential of unmanned aerial vehicle. The aim of this paper is to gives an overview of solar-powered drones and their design for a 36-hrs endurance flight.


Aspect-oriented programming is a new paradigm that separates the different concerns to improve the modularity. This paradigm introduces new validation challenges. To offer effective solutions to these problems, 38 open source projects have been analyzed to study the use of aspects. To address observed problems, automatic analyzes have been proposed. The objective of the first analyses is to statically determine which test cases are impacted by the aspects and should be modified to take the changes into account. The second analyses aims at testing the pointcut descriptors separately from the advices, to have better and more precise oracles. Tools have been developed to support and validate this analyzes.


The aim of this study was to define influence of different housing systems and barns on costs and energetic inputs in milk production and assessment of microclimate conditions. There were twelve free-stall cattle barns for dairy cows tested and the analysis contains: investment costs of buildings, equipment for mechanization of technological treatments (milking and milk cooling, forage preparing and feeding, manure removing and storing and other works), electric and mechanical energy inputs, labour inputs, exploitation costs of equipment and buildings, concentration of harmful gases, temperature of air and relative humidity inside and outside of barns. The limitations to the choice of the best technicaltechnological solution were assumed: average investment cost ≤ 19000 PLN, average labour inputs ≤ 4,6 working minutes, electric energy inputs ≤ 0,40 kWh, mechanic energy inputs ≤ 2,006 HP, NH3 concentration ≤ 10,9 ppm and CO2 concentration ≤ 1500,8 ppm. These values are per day and per LU. The best functional technological solutions were in two barns, which fulfilled all limitations. It were: one boxed cattle barn with litter and one boxed non-littered barn, both with high number of animals, 144 LU and 109 LU respectively. Simultaneously in these two barns the lowest unitary exploitation costs were calculated and amounted to 1710,98 PLN LU and 2088,57 PLN LU.


This review summarizes the modern medical imaging technique in temporal bone.HRCT was the first choice of medical imaging in temporal bone,it has the dominant advancement in disease and anatomy in temporal bone.Spiral CT have many post procession techniques:MPR can display the temporal bone with different angles,CPR can show the facial nerve as a whole.SSD,CTVE can display the disease and anatomy in temporal bone in a stereoscopic way and can simulate the surgery,VR can show the membrane labyrinth and nerves in inner ear.MRI can differentiate the lesions from pathologic constituents to some extent.Hydrography can display the membrane labyrinth clearly.MRI is a useful complement way of medical imaging in temporal bone.


As the number of cyberattacks grows exponentially, it is crucial to identify and categorise these attacks. One significant cyber hazard that has a significant impact on many different industries is malware. The paper examines the already published literary works. The suggested solution utilises a malware dataset containing 210352 samples that was gathered from Kaggle. Eight different classifiers, including support vector machines, K-nearest neighbours, Naive Bayes, logistic regression, and tree-based methods like random forests and decision trees, are used with separate training and testing sets of data. The outcomes are also contrasted with ensemble learning strategies like gradient boosting and adaboost. For experimental work, many classifier types are chosen. The outcome demonstrates that the random forest classifier outperforms the other classification methods by providing 98.02% accuracy. As a result, the paper uses machine learning methods to categorise malware, and the authors are presently attempting to enhance the system's performance by creating convolution neural networks, making the system more flexible to new infections.


The paper deals with complexity theory as a tool for better understanding of change management. The introduction analyzes the current state of the business environment, the increasing complexity and especially increased demand for products and processes.

Having access to accurate game state information is of utmost importance for any artificial intelligence task including game-playing, testing, player modeling, and procedural content generation. Self-Supervised Learning (SSL) techniques have shown to be capable of inferring accurate game state information from the high-dimensional pixel input of game footage into compressed latent representations. Contrastive Learning is a popular SSL paradigm where the visual understanding of the game's images comes from contrasting dissimilar and similar game states defined by simple image augmentation methods. In this study, we introduce a new game scene augmentation technique—named GameCLR—that takes advantage of the game-engine to define and synthesize specific, highly-controlled renderings of different game states, thereby, boosting contrastive learning performance. We test our GameCLR technique on images of the CARLA driving simulator environment and compare it against the popular SimCLR baseline SSL method. Our results suggest that GameCLR can infer the game's state information from game footage more accurately compared to the baseline. Our proposed approach allows us to conduct game artificial intelligence research by directly utilizing screen pixels as input.


The instructional leadership mod el in Figure 1 is based on re search on organization and man agement theory and on work with thousands of principals across the coun try. In the model, the school year is divided into three parts with a major instructional leadership function for each: planning (September and Octo ber), developing program and staff (No vember through April), and evaluating (April and May). Collaborative decision making, prob lem solving, and planning are necessary to the success of activities. Continuous collaboration among teachers, parents, students, and principals tends to pro duce a healthy school climate, which also influences success or failure. While the instructional leadership model out lines the principal's tasks, success de pends, first of all, on a vision of what is possible; second, on collective reflection and action; and, third, on the ability of those involved to work together produc tively. Thus, the instructional leader ship model outlines the tasks of the principal and assumes that collaboration is the norm, with role isolation dimin ishing. School Planning Decisions about school improvement targets are made at several levels. The state agency as well as the local school district determine certain thrusts during certain years. These external expecta tions are assigned to each school for specific attention. Principals, after as sessing school productivity needs, also determine areas for improvement over a year or more.


This article seeks to show how the genre of the coq‐à‐l'âne created by Clément Marot regained popularity at the end of the sixteenth century in the midst of the Wars of Religion. These poems are usually anonymous, composed by members of one or another of the three warring groups (Catholics, Protestants, and 'Politiques'). They create an impression of absurdity that is nonetheless militant. Characterized by a loose structure and the use of animal metaphors, they employ a form of partisan rhetoric that is both aggressive and comic. The vogue for coq‐à‐l'âne, which were frequently set to music and sung, can also be seen as proof that the religious and political arguments were by now exhausted: all that remained was the desire to ridicule one's enemy, to destroy him with word games. This strategy was typical of French writing in the late Renaissance: when used in militant and comic texts the vernacular could reach out to the entire nation.


Finding new leukemia genes undoubtedly has important significance for revealing its pathogenesis and seeking its effeetive treatment.In this research we chose 330 physical and chemic features of mRNA and protein and found certain of these features showed similar significant differences on known disease genes of five kinds of leukemia(T-ALL,ALL,AML,APL and JML).This property was used to develop a novel approach to predict leukemia disease genes.Test results demonstrate that this approach can effectively detect actual leukemia disease genes from numbers of candidate genes and the effect of this approach obviously exceeds other approaches.


Data hiding is a technique for embedding secret data into cover media. It is important to multimedia security and has been widely studied. Reversible data hiding methods are becoming prevalent in the area because they can reconstruct the original cover image while extracting the embedded data. In this paper, we propose a new reversible method for vector quantization (VQ) compressed images. Our method takes advantages of the relationship among the side match neighbouring (SMN) blocks to achieve reversibility. The experimental results show that the proposed method has higher compression rate and larger capacity than other existing reversible methods.


The evolution of biased sex ratios in a randomly structured population stems from individual selection acting through local parental control (LPC) of the sex ratio and hence of the mating success of the sons and/or daughters. As a general rule, the sex ratio is biased away from the sex whose fitness is most affected by changes in the local sex ratio. This is the sex whose fitness is subject to the most effective parental control. The bias acts to increase the fitness of the rarer, controlled sex and to increase parental productivity. In the specific case of the evolution of the female‐biased Hamiltonian ratios, LPC can affect the mating success of sons but has no effect on the success of daughters.


Natural plant fermentation dregs useful as cosmetic material extracts are provided to reduce production costs, and improve functionality and safety of cosmetics, and induce skin moisturizing, improvement of skin color, skin aging inhibition and skin whitening by supplying vitamins and minerals derived from plants to the skin. A manufacturing method of the cosmetic material extracts comprises the steps of: naturally fermenting edible natural plants including dandelion, wild chrysanthemum, pine, mugwort, mulberry leaf, arrowroot and its leaf, acacia, forget-me-not, shepherd's purse, motherwort and balloonflower to prepare 95 wt.% of dregs containing 80 wt.% of fiber and lignum solids and 15wt.% of undiluted solution; compressing the fiber and lignum solids with a compressor to obtain the dregs; pulverizing the dregs to 60-1000 mesh; and mixing the pulverized dregs with 5 wt.% of supplemental materials including a natural or cosmetic thickening agent.


【In the Internet-based B2C e-commerce, trust has been recognized as a critical factor to reduce uncertainties, through interacting with a well-known specific shopping mall. In this study, we view customer trust as not a unitary concept but multidimensional one consisted of the trustworthiness of trustee, familiarity with the specific shopping-mall, disposition to trust, and institution-based trust. In this study, first, we considered the trustworthiness of trustee consisted of capability, benevolence, and integrity as one of the major factors to build customer trust on the specific Internet shopping-mall. In the context of the Internet e-commerce, the role of institutional structures is very important to assure the customer trust from the various opportunistic behaviors because of the characteristics of internet-based commerce such as impersonality, the lack of information on the other party, and the transactions with a number of anonymous people. Second, we examined the effect of the institution-based trust built by institutional structures on customer trust. Third, we examined the effect of customer trust and familiarity on retaining customer loyalty. Our findings showed that customer trust and familiarity played a major role in retaining customer loyalty with the specific shopping-mall. In conclusions, we discussed the strategies to build the customer loyalty for maintaining the customer. We suggest customer trust and familiarity for the factors to bind the customer with the specific shopping-mall based on these results.】

Energy will become the major issue for international stability in the next century as the world's population grows and people move away from regions with inadequate energy supplies. Even conservative estimates of population growth indicate that major progress in energy conservation and renewable energies will not be enough to sustain humanity Beyond the middle of the next century new sources of energy that have a low impact on the environment and produce relatively harmless waste will be needed.


This paper provides an update of the paper 'From R&D to Productivity Growth: Do the Institutional Settings and the Source of Funds of R&D Matter?' (Guellec and van Pottelsberghe 2004). We present estimates of the long-term impact of various sources of knowledge (R&D performed by the business sector, the public sector (higher education and government) and abroad) on the multifactor productivity growth of 17 major OECD countries from 1988 to 2006. The results confirm that business R&D and the R&D performed by the higher education sector significantly contribute to growth. In addition, the extent to which countries rely on triadic patents, as well as their degree of patent friendliness (enforcement mechanism and number of restrictions) affect significantly the extent to which R&D contributes to growth.


We propose an extended framework of social choice, which incorporates the common morality of the society. The purpose of this paper is to investigate the role of common morality in social decision situations. Common morality includes non-welfaristic considerations such as rights, procedures, and historical considerations. Each individual has a comprehensive preference based on welfare and common morality. First, we consider the society, where there exists at least one common-sense moralist who always gives unequivocal priority to common morality. The existence of a common-sense moralist is indispensable to satisfy the desirable requirements in a social decision. A (comprehensive) social preference is amalgamation of individual comprehensive preferences of the members in the society. We impose three well-known Arrovian conditions, namely, the Pareto principle, independence of irrelevant alternatives, and non-dictatorship, on a social ordering function. Under such conditions, social preference ordering gives unequivocal priority to common morality. In other words, we characterize a social preference ordering which has a non-welfaristic feature. Our result implies that common-sense morality in the society plays a crucial role for the evaluation of social decision situations. Furthermore, we consider the general domain of common morality, which is the largest domain consistent with the existence of common morality, and impose modified versions of the Arrovian conditions. Under the general domain of common morality, there exists no common-sense moralist. We show that under these conditions, social preference ordering gives unequivocal priority to common morality.


Infrasound observation measures the energy radiated by a snow avalanche into the atmosphere and can be used to detect snow avalanches over large areas. Our research team has conducted infrasound observation in Tokamachi, Niigata Prefecture, Japan, during the last three winter seasons. First, between January and April 2013, we deployed an infrasound sensor in front of a selected slope, obtained visual observations using a web camera, and identified infrasound signals generated by snow avalanches. During the second season (2013-2014 winter), we deployed two infrasound sensors approximately 1 km apart and obtained the attenuation characteristics of infrasound signals. In the 2014-2015 winter season, we deployed three sensors spaced at 1-2 km in a triangular array and attempted automatic extraction of signals associated with snow avalanches from observed raw data using time-domain processing. For the extracted signals, the locations of snow avalanches were estimated with the cross-correlation method. Twelve e...


Globalization and highly competitive business environment are pushing many organizations to realize numerous productivity improvement efforts in order to continue to survive. To gain competitive advantage, manufacturing organizations are compelled to adopt productivity enhancement programs such as total quality management (TQM), total productive maintenance (TPM), lean manufacturing concept to achieve operational excellence. Overall Equipment Effectiveness (OEE) is a well-accepted production performance measure to gauge the equipment effectiveness. OEE is defined as how much the equipment is performing to meet the production planned target. OEE, in manufacturing is merely a percentage figure to evaluate how effective the manufacturing equipment is utilized. OEE is not directly linked to profitability. Most companies do not associate increases or decreases in OEE to financial performance. This paper presents the relationship between OEE, production throughput and production part cost in order to express and translate OEE in monetary units.


Intense optical pulse propagation in a GeO2-doped silica glass fiber grating results in nonlinear pulse propagation velocities and increased transmission at wavelengths where the grating reflects light in the linear limit. These nonlinear pulse propagation effects are predicted by numerical simulations of gap soliton propagation. The large linear refractive-index variations used for the fiber gratings in these experiments permit the propagation of gap solitons in short lengths of fiber.


1. In forest communities, the Janzen–Connell (J–C) model proposes that species diversity is maintained by noncompetitive distance‐ or density‐dependent seedling mortality caused by host‐specific natural enemies. Host specificity, however, has not been fully elucidated.

He did not write too many works but his works are all refined. This phenomenon of refinement is closely related to his refined consciousness,basis,ideal and help.


Background: Understanding leg stiffness (Kleg) in amputee sprinters is important for the evaluation of their sprint ability and development of running-specific prostheses (RSP). Objectives: To investigate Kleg during hopping in amputee sprinters. Study Design: Cross-sectional study. Methods: Seven transtibial (TT) and seven transfemoral (TF) amputee sprinters, as well as seven non-active able-bodied subjects, performed one-legged hopping matching metronome beats at 2.2 Hz. Amputees hopped on their sound limb whereas able-bodied (AB) subjects hopped on their dominant limb. Using a spring-mass model, Kleg was calculated from the subjects' body mass, ground contact and flight times. Results: Both TT and TF sprinters demonstrated significantly higher Kleg than AB subjects. Kleg during hopping on the sound leg significantly correlated with personal records attained in a 100-m sprint in both TT (r = −0.757) and TF sprinters (r = −0.855). Conclusion: The results of the present study suggest that amputee sprinters have a greater Kleg during hopping than inactive non-amputees, and that their sprint ability can be predicted from the Kleg during hopping at 2.2 Hz on the sound limb. Clinical relevance Exercise challenges need to be taken into consideration when planning routine training regimens for amputee sprinters. Furthermore, increased understanding of Kleg in amputee sprinters is relevant to evaluate their sprint ability and develop running-specific prostheses.


The optical characteristics and waveguide index profiles of Z-cut LiNbO_3 optical waveguides which fabricated by using a new proton source formed by a mixture of adipic and benzoic acids with different values of the adipic-benzoic acid concentration ratio were studied.The experimental results show that the optical waveguides present β_4-phase when high concentration ratio, while present β_3-phase when relative low concentration ratio under the exchange temperature of 230℃ exchange time of 6 h. The higher the concentration ratio, the greater the surface refractive index change and waveguide depth of the optical waveguides in β_4-phase, and the difference of optical properties in β_3-phase is not significantly. The optical waveguides fabricated by using single benzoic acid and 60% ratio dilution were analyzed by double crystal X-ray diffraction. The results give useful information in making optical waveguides and to understand the physical mechanism of refractive index change in the LiNbO_3 optical waveguides.


Using an eigenfunction expansion to solve the transport equation, complemented by Monte-Carlo simulations, we show that ultrarelativistic shocks can be effective particle accelerators even when they fail to produce large amplitude turbulence in the downstream plasma. This finding contradicts the widely held belief that a uniform downstream magnetic field perpendicular to the shock normal inhibits acceleration by the first order Fermi process. In the ultrarelativistic limit, we find a stationary power-law particle spectrum of index s=4.17 for these shocks, close to that predicted for a strictly parallel shock.


Angular-dependent reflectivity techniques are employed to probe the exciton-polariton states of a semiconductor quantum microcavity. The spectra exhibit marked polarization dependence, with the energies, line widths, and intensities all differing between transverse-electric and transverse-magnetic polarizations, consistent with the predictions of transfer-matrix simulations. In addition, anomalous narrowing of the spectra on resonance, broadening of the cavity mode by interaction with exciton continuum states and interaction of the cavity mode with quantum-well excited-state transitions are reported. @S0163-1829~97!52040-6#

Internal control involves everything that controls risks to a bank. The objectives of internal control as a system relate to the reliability of financial reporting, timely feedback on the achievement of operational or strategic goals, and compliance with laws and regulations. The objectives of internal control at a specific transaction level refer to the actions taken to achieve the target within the allowed limit of risk. An effective internal control system reduces process variation, leading to more predictable outcomes. There are some important documents for regulating the internal control system as such: The Directive 2006/43/EC "On statutory audits of annual accounts and consolidated accounts", published by the European Commission in 2006; 8th Company Law Directive of the European Union, Article 41; "The internal audit function in banks," Basel Committee on Banking Supervision, 2012; "Corporate Governance Principles for Banks" Basel Committee on Banking Supervision, 2015. It should be noted that Albania, an EU candidate country, is approaching the EU directives and Basel principles via legislation and regulation framework. Related to bank's internal control system, its structure and responsibilities, Albania has taken periodically the way of accommodating the requirements of EU directives and Basel principles within the law no. 9662, dated 18.12.2006 "On Banks on the Republic of Albania", amended; regulation no. 63, dated 14.11.2012 and lately the new regulation, dated on 02.09.2015 "On Internal Control System". This last one, has given the minimum requirements for setting up an effective internal control system and supporting arrangements by the three lines of defence model; a strong internal control system, including an independent and effective internal audit functions, as part of sound corporate governance; the findings of internal audit to be followed and bank's management to take appropriate and timely corrective action in response to internal control weaknesses; the internal audit to provide vital assurance to bank's board of directors and supervisors with whom should be an enhanced two-way communication for discussing the risk areas identified, measures received, etc. This paper aims to inform bankers, researchers, and other stakeholders with some principles of internal control system regulated in Albania as well as raising some other related issues to be considerate for ensuring the efficiency and effectiveness of internal control system of banks in Albanian.


We develop two classes of criteria for multivariable rationality with bounds on degree or other restrictions of the permitted exponent set. The first class is expressed in terms of differential algebra and shows that rational functions with prescribed exponent sets form a differential algebraic variety expressed by a finite collection of explicit differential relations. The second class concerns characterizations in terms of Taylor series coefficients, including one approach using rationality along radial one-dimensional slices, thus it extends a classical one variable result. In the first class, we develop results pertinent to the cases of zero and prime characteristic, while our Taylor coefficient results focus solely on characteristic zero.


Aquaculture is a highly profitable venture in India. Also, it has availability of nutritive food for the growing population. Cows were regarded as wealth and were the backbone of the economy of ancient Indians. Cow urine is considered to be the most effective animal origin substance having intrinsic property of general health improvement. (Gir) Cow urine were used in this present study, to evaluate its efficiency in enhancing growth and improving in mrigala fingerlings, one of the Indian major carps.

A general design approach is presented for model-based control of piston position in a free-piston engine (FPE). The proposed approach controls either 'bottom-dead-centre' (BDC) or 'top-dead-centre' (TDC) position. The key advantage of the approach is that it facilitates controller parameter selection, by way of deriving parameter combinations that yield both stable BDC and stable TDC. Driving the piston motion towards a target compression ratio is therefore achieved with sound engineering insight, consequently allowing repeatable engine cycles for steady power output. The adopted control design approach is based on linear control-oriented models derived from exploitation of energy conservation principles in a two-stroke engine cycle. Two controllers are developed: A Proportional Integral (PI) controller with an associated stability condition expressed in terms of controller parameters, and a Linear Quadratic Regulator (LQR) to demonstrate a framework for advanced control design where needed. A detailed analysis is undertaken on two FPE case studies differing only by rebound device type, reporting simulation results for both PI and LQR control. The applicability of the proposed methodology to other common FPE configurations is examined to demonstrate its generality.

1n which yields a time-dependent deceleration parameter. It is observed that for n 1, the models are not physically feasible whereas for n 1, we can generate a class of physically viable models. It is also detected that the models of the universe have a transition from early decelerated phase to the recent accelerating phase at present epoch which is consistent with recent astrophysical observations. The study reveals that massive strings dominate in the early universe. The strings eventually disappear from the universe for sufficiently large times, which is in agreement with current astronomical observations. Some physical and geometric aspects of the models are also discussed. Index Terms—String, Bianchi type I universe, Variable deceleration parameter, Accelerating universe


INTRODUCTION Previous work on crystal nucleation in one-component melts has largely been confined to molecular liquids or metals. Molecular liquids have been studied in bulk", and in the form of clouds of droplets produced by condensation in supersaturated vapourv". Metals have also been studied in bulk 7, 8, and as droplets of microscopic size. These were produced either singly by melting small fragments 9, 10, or in large numbers in emulsions-l12. For some purposes it is an advantage, in studying supercooling, to subdivide a sample of melt into a large number of droplets, thereby reducing to a small fraction the number which might contain impurities. In particular, only droplets free from impurities may be relied upon to exhibit phenomena of spontaneous nucleation. Apart from work on glasses, where crystallization is very slow, little information exists on the spontaneous nucleation of ionic melts. In spite of experimental difficulties due to their high melting points, work on inorganic salts containing simple ions seems likely to prove rewarding, especially in view of the additive properties ofthe inter-ionic forces. Central, Coulombic force fields are more amenable to theoretical treatment than those in other classes of compounds, as is evident from the considerable success with which they have been used to predict the lattice energies of ionic solids. A short description is given below of a new technique for studying the solidification of molten salts at high temperatures, together with some preliminary results obtained with alkali halides.


In this paper, we introduce and investigate the notions of Iω -continuous maps and Iω -irresolute maps in ideal topological spaces. Also we introduce the notions of slc*-I -sets, s -sets, λs - I -closed sets, slc* - I -continuous maps and λs - I -continuous maps. Finally, we obtain the decompositions of  -continuity.


In today economics-oriented competitive environment which is based on knowledge, the organization's knowledge & intellectual capital(IC) is recognized as a competitive advantage for organizations. The intellectual capital is the key driver for academic competition & performance betterment. The organization not able to develop its IC won't have the capability to survive & organizational trust (OT) plays a fundamental role in the development of organization's IC. The present study pursues the goal to compare the intellectual capital & organizational trust in Mazandran Medical Sciences University. The research is descriptive-correlative where the statistical community includes all faculty members of Mazandran Medical Sciences University. The sampling method is categorized random based on which 264 subjects have participated in the study. Two researcher-made questionnaires have been used as the measurement tool. Face validity & content validity have been used to establish the questionnaires' validity. To determine reliability, α-Cronbach has been used. The α-Cronbach has been obtained 0.87 for intellectual capital and 0.81 for organizational trust. In order to analyze the data, inferential statistics (correlation coefficient & t-test) tested by SPSS software have been applied. The study derived findings suggest that there is no meaningful difference between organizational trust and intellectual capital among female & male faculty staff. There is no significant difference between organizational trust and intellectual capital among the clinical training groups & basic sciences. The correlation coefficient results imply that a meaningful relationship exists between organizational trust and intellectual capital & its dimensions (human capital, structural capital, relational capital & innovation capital). Mazandran Medical Sciences University directors and officials are recommended to pay attention to all dimensions & components of IC in the organizational promotion plans & also to increase the organizational trust in order to develop intellectual capitals among the university staff.


Seed production areas containing populations of native grasses were fenced on topographically high areas at two study sites in the semiarid rangelands of north-west New South Wales, Australia. The surrounding slopes were initially almost bare of pastorally preferred grasses. Three restoration treatments (control, mechanical pitting, and contour-aligned branch piles) were established on these surrounding slopes and the size and composition of the native grass seedbanks determined. A positive influence of the seed production areas mostly occurred within 15 m of the fence and was probably insignificant beyond 33 m at both sites. On a hard-setting red earth site, the size of the native grass seedbank in all three treatments increased over 2 years with the greatest increase under the piles of branches and smaller increases in the pitting and control treatments. The piles of branches preferentially incorporated seed of the pastorally preferred species Monachather paradoxus Steud into the seedbank whereas pits preferentially incorporated seed of the pastorally unpreferred species Aristida jerichoensis (Domin) Henrad. Evidence generally pointed to incoming seed rain rather than the seedbank as the main source of new seedlings. On a medium-textured lithosol site neither the pits nor the branches treatment was effective in enhancing either the size or composition of the seedbank; in fact the piles of branches resulted in a decrease in its size.


The celebrated integer relation finding algorithm PSLQ has been successfully used in many applications. PSLQ was only analyzed theoretically for exact input data, however, when the input data are irrational numbers, they must be approximate ones due to the finite precision of the computer. When the algorithm takes empirical data (inexact data with error bounded) instead of exact real numbers as its input, how do we theoretically ensure the output of the algorithm to be an exact integer relation?
In this paper, we investigate the PSLQ algorithm for empirical data as its input. Firstly, we give a termination condition for this case. Secondly, we analyze a perturbation on the hyperplane matrix constructed from the input data and hence disclose a relationship between the accuracy of the input data and the output quality (an upper bound on the absolute value of the inner product of the exact data and the computed integer relation), which naturally leads to an error control strategy for PSLQ. Further, we analyze the complexity bound of the PSLQ algorithm for empirical data. Examples on transcendental numbers and algebraic numbers show the meaningfulness of our error control strategy.

The way school principals liaise with each other and the wider community has evolved dramatically. De La Salle College Principal Michael Egan tells IE Journalist Daniel Long how Twitter is influencing the way educators communicate.


in many respects a straightforward history and overview of Cuban music, with relatively little interpretive or conceptual framework. As it remains the finest work of its kind on Cuban music, an English translation has been overdue, and the present edition—with a lengthy introduction by Timothy Brennan—is a welcome contribution to studies not only of Cuban music, but also Caribbean and Latin American culture in general. Moreover, as Brennan argues, Carpentier's study was in its own way a landmark in the growing legitimization of New World and especially Afro-Latin vernacular culture. Alejo Carpentier (1904–1980) was primarily a novelist and arts journalist, and in his latter decades served as a senior cultural minister for the Castro government—a post that earned him the contempt of exiles like Guillermo Cabrera Infante. Although not a musicologist by training or profession, Carpentier was an intellectual and a classically trained pianist, and when receiving a commission from the Mexican government to write his study of Cuban music, he conducted a considerable amount of original archival research. This work combined with his gift for writing to produce a truly outstanding opus that, among other things, represents the finest tradition of Cuban intellectual literature. In his insightful introduction, Brennan stresses Carpentier's remarkably pluralistic and inclusive approach, which led him to devote chapters not only to Afro-Cuban music but also to the commercial popular idioms for which Cuba has subsequently become so


The culture and the arts are essential elements of a complete education that leads to the full development of the individual. The artistic education is a universal human right, including those that many times are excluded from the education, as the minority groups and people with deficiency. This project has resulted from the creation of a Dance/Theatre group, having as main objective creating and presenting new creations as well as the development of a space for reflection, personal awareness and theoretical research at the crossroads between the performing arts and the social and cultural inclusion.


The paper considers the curing process of a thermosetting unidirectional glass/epoxy composite material system. The curing is designed as a two-stage cycle, where the two-stage curing refers to the curing of one area of the laminate prior to the other. The purpose of this is to develop cure induced residual stresses in the laminate aiming for a future examination of their effect on the mechanical properties. The aim of this paper is to confirm that the developed mould tool has the ability to achieve a well-defined two-stage curing cycle. Furthermore, the predictions of a numerical model of the curing process against measured Tg values for the considered glass/epoxy system is validated.


Objective—Factors and mechanisms that activate macrophages in atherosclerotic plaques are incompletely understood. We examined the capacity of heparanase to activate macrophages. Methods and Results—Highly purified heparanase was added to mouse peritoneal macrophages and macrophage-like J774 cells, and the levels of tumor necrosis factor-α, matrix metalloproteinase-9, interlukin-1, and monocyte chemotactic protein-1 were evaluated by ELISA. Gene expression was determined by RT-PCR. Cells collected from Toll-like receptor-2 and Toll-like receptor-4 knockout mice were evaluated similarly. Heparanase levels in the plasma of patients with acute myocardial infarction, stable angina, and healthy subjects were determined by ELISA. Immunohistochemistry was applied to detect the expression of heparanase in control specimens and specimens of patients with stable angina or acute myocardial infarction. Addition or overexpression of heparanase variants resulted in marked increase in tumor necrosis factor-α, matrix met...


We have measured the near-infrared colors and the fluxes of individual pixels in 68 galaxies common to the Spitzer Infrared Nearby Galaxies Survey and the Large Galaxy Atlas Survey. Pixels from each galaxy are grouped into regions of increasingly red near-infrared colors. As expected, the majority of pixels are shown to have relatively constant NIR flux ratios (log10 I3.6/I1.25 = −0.30 ± 0.07 and log10 I4.5/I3.6 = −0.19 ± 0.02), representing the blackbody continuum emission of main sequence stars. However, pixels with red NIR colors correspond to pixels with higher Hα emission and dust extinction. We show that the NIR colors are correlated to both quantities, with the strongest correlation to the intrinsic Hα emission. In addition, in regions of high star formation, the average intensity of pixels in red-excess regions (at 1.25 μm, 3.6 μm, 4.5 μm, 5.6 μm, 8.0 μm and 24 μm) scales linearly with the intrinsic intensity of Hα emission, and thus with the star formation rate (SFR) within the pixel. This suggests that most NIR-excess regions are not red because their light is being depleted by absorption. Instead, they are red because additional infrared light is being contributed by a process linked to star formation. This is surprising because the shorter wavelength bands in our study (1.25 μm–5.6 μm) do not probe emission from cold (10–20 K) and warm (50–100 K) dust associated with star formation in molecular clouds. However, emission from hot dust (700–1000 K) and/or polycyclic aromatic hydrocarbon (PAH) molecules can explain the additional emission seen at the shorter wavelengths in our study. The contribution from hot dust and/or PAH emission at 2 μm–5 μm and PAH emission at 5.6 μm and 8.0 μm scales linearly with warm dust emission at 24 μm and the intrinsic Hα emission. Since both are tied to the SFR, our analysis shows that the NIR excess continuum emission and PAH emission at ∼1–8 μm can be added to spectral energy distribution models in a very straightforward way, by simply adding an additional component to the models that scales linearly with SFR.

This article borrows from the literature on transitional democracies to examine levels of support for democracy and non-democratic alternatives among immigrants travelling from partly and non-democratic countries to Canada. It evaluates how immigrants who grew up under authoritarian rule come to adapt to democracy. The findings indicate that immigrants from partly and non-democratic countries experience tensions in their adaptation to democracy, expressing strong democratic desires but also manifesting what could be interpreted as lasting imprints of their socialization under authoritarian rule. Immigrants from partly and non-democratic countries exhibit strong support for democracy (they almost all believe it is a good form of government, the best one, and understand democracy in broadly similar terms as the rest of the population). Yet, if democracy is the main game in town for the immigrants, it is not the only one; immigrants from partly and non-democratic countries are significantly more likely than people socialized in a democratic political system to support other forms of governments that are non-democratic. The article thus argues for the lasting impact of authoritarianism on people's democratic outlooks despite the presence of strong democratic desires.


A geotextile, installed at the interface of subsoil and fill in road, railroad, or water construction, has to fulfill the separation function properly. As a consequence, the separating geotextile has to resist the installation procedure, the consequent tipping of aggregate and furthermore the access and permanent traffic loads, undamaged. A new abrasion test modeling interface actions is presented in this paper. Resistance to abrasion damage as derived from laboratory testing has proved to indicate actual behavior in the field.


This article uses content analysis and webometric approaches to examine the challenges associated with e-government and the presence and performance of African governments on the web, as well as to review and compare the availability and use of various types of information and communication technologies (ICTs) in making e-governance possible in the region. Results indicate that despite the challenges faced by countries in Africa, the presence of African governments on the web is improving, and a number of ICTs and related tools are becoming increasingly available; moreover, between 2000 and 2009, Africa experienced the second highest growth rate in terms of internet usage. There are few interlinkages between government websites, and most African governments are in the initial stages of e-governance uptake. External information to which the governments provide links includes freeware, news and general information (e.g. tourism). Recommendations for the effective implementation of e-governance are provided.


This paper presents a novel concurrency control method for real-time database transactions: semantic multi version concurrency control protocol(SMVCC).It utilizes semantics of real-time transactions and multi version data in real-time databases to manage different transactions with different policies according to view consistency,and as a result,SMVCC gets more concurrency performance.


KCl Cotransport (KCC) is highly expressed in sickle red blood cells (SS RBC) and recent data have demonstrated its abnormal response to cell swelling and acid pH. We showed that the final MCHC achieved by SS reticulocytes upon activation of KCC by these stimuli was higher than that of normal (AA) reticulocytes (Joiner et al, Blood, in Press ). Here we report studies examining the sensitivity of KCC to activation by urea at concentrations present in the kidney and the effect of urea stimulation of KCC on reticulocyte MCHC. KCC fluxes were assayed as Rb uptake over 20 min in isotonic saline solutions buffered with HEPES to pH 7.4 (37°C) containing 0.1 mM ouabain, and 0.01 mM bumetanide, with 27 mM RbCl replacing equimolar NaCl. Under these conditions > 95 % of Rb uptake was Cl-dependent (assessed by sulfamate replacement of Cl). The maximal volume-stimulated KCC flux (VSmax KCC) was measured for each sample in cells swollen isotonically to MCHC Final Reticulocyte MCHC, gm/dl [mean (SD), n = 3] Urea (600 mM) enhanced RVD in both AA retics and SS retics. Sulfhydryl reduction with DTT had no effect on urea-stimulated RVD in SS reticulocytes. RVD stimulated by urea was complete within 60 minutes, and was irreversible: additional incubation without urea did not lower MCHC. The partially dehydrating effect of brief (10 min) exposure to urea was also irreversible, and was cumulative: cells exposed to two 10 min exposures to high urea (600 mM), separated by 10 min at a low, non-stimulating concentration of urea (100 mM), yielded the same MCHC as a continuous 20 min exposure. These data demonstrate that urea, at concentrations found in the renal medulla, is a powerful stimulant of KCC and intiates a striking RVD in reticulocytes. To the extent that intermittent stimulation of KCC by urea in the kidney occurs in vivo , this could contribute an exaggerated RVD resulting in dehydration of SS reticulocytes.

PurposeBuilding circulation has an important impact on human comfort of buildings and is one of the critical factors in building design. A quantitative walkability evaluation of building circulation can benefit both building design and operation. However, indoor walkability of building circulation is determined not only by objective path features but also by subjective user preference. How to incorporate the preference from a large group of users into the design process is still a challenging issue.Design/methodology/approachThis study proposes a participatory framework of indoor path walkability evaluation based on user preference. Hierarchical indicators are developed to objectively measure indoor path features. Furthermore, group decision-making theory is adopted to aggregate individual user preference into user common preference for determining the relative indicator weights. Finally, integrated walkability scores (IWSs) are calculated to evaluate indoor path walkability quantitatively.FindingsA total of three case scenarios demonstrate that the proposed evaluation framework provides an efficient way for designers and owners to measure user preference quantitatively, analyze building circulations based on user preference and compare the walkability of different building design schemes.Practical implicationsThe developed methods provide an efficient way for designers and owners to measure user preference quantitatively, analyze building circulations based on user preference and compare the walkability of different building design schemes.Originality/valueThis study develops a comprehensive and quantitative walkability evaluation approach that considers both objective path features and subjective user preference derived from user characteristics and walking purposes, which provides an effective way to incorporate user feedback into the building design process and operation.

This insulated gate type transistor consists of an insulating layer, an active layer made of a first conductive type semiconductor formed on the insulating layer, and a cathode region made of a high impurity concentration semiconductor. The IGFET manufacture for three- dimensional LSI has the thickness of active layer equal to half PI time debye wavelength of the constituent semiconductor. This transistor is constructed as a gate insulated type so as to provide not only a current saturation characteristic but also a nonsaturative characteristic.


fascinating glimpse of the role of women workers in telephone companies. Curiously, she does not cite Elinor Langer's well-known, "Inside the New York Telephone Company" (1970). At the other end of the table, Schegloff relentlessly invests a commonplace subject with an elaborate superstructure of jargon that borders on self-caricature. Gottmann and Abler offer different but worthwhile insights into the relationship between the telephone and city. Brooks treats the telephone in literature in a superficial and unsatisfying manner. Pierce's essay on "The Telephone and Society" wraps some interesting data and observations around a hymn of praise to Ma Bell and the free enterprise system. It is, in short an uneven book: worthwhile in that it covers a much neglected subject as nothing else available does, and frustrating in that, like party-line gossips, it often talks a great deal about its subject without saying much.


The sensitivity analysis plays an important role and significance in optimizing the slope angle and curing the landslide of mines.Taking section 2-2' of SICOMINES slope in Congo(Kinshasa) for example and considering the influencing factors as weight,cohesion,underwater and the friction angle of rock and soil,the main target for controlling the landslide could be defined through the stability and sensitivity analysis of the slope,and the optimal slope angle could be obtained for the mine.In this case,the initially designed slope angle is in stability,and the stripping ratio could be reduced,the mining costs could be lowered,then the economic efficiency could be improved.


We consider the set of permutations that are sortable after two passes through a pop stack. We characterize these permutations in terms of forbidden patterns and enumerate them according to the ascent statistic. Then we show these permutations to be in bijection with a special family of polyominoes.


Fatigue driving detection technology based on the external characteristics of the driver has made some progress in many aspects, but the method of driver facial feature extraction needs to be further improved, and the driver's eye location takes a long time, which affects the system recognition rate. The paper uses the fatigue driving detection method to achieve better results than the traditional detection method. The authors applied the convolutional neural network to face recognition, and improve the pupil localization algorithm, effectively overcoming the problem of large calculation of the original algorithm. According to the characteristics of driver's eyes with different width and height ratios in different states, a simple and feasible method of eye state judgment is realized, and the driver's fatigue state is judged by PERCLOS algorithm. The convolutional neural network model is applied to ORL face database, and the face recognition rate is 85%. The improved Hough transform method has a positioning accuracy of 92% for the driver's eyes, respectively, and the recognition rate for the driver's eye state is 83.9%. The authors designed the prototype system of fatigue driving detection based on face recognition which realizes the functions of driver's face feature detection, eye location, eye state judgment and fatigue judgment. The experimental results show that the recognition rate of fatigue is 87.5%.


The aim of this paper is to investigate the entropy generation in a flow over a flat plate with slip-flow boundary layers. Laminar flow at steady state is considered with two different forms of thermal boundary conditions, i.e., constant heat flux and constant temperature at wall. The effects of viscous dissipation, velocity slip and temperature jump at wall have been taken into consideration. Entropy generation was shown to decrease with an increase in the value of K, while increasing Br, Br/ϕ and Pr results in increasing the entropy generation.


During the first MAPTIP workshop in Oslo, Norway (May 94) after the trial (Oct. 93), a number of working groups were created. These groups reported some of their joint findings at the second workshop in Quebec City, Canada (May 95). This presentation summarizes the results obtained by the 'refractive effects in the visible and the IR group.' The experimental setups of the three different groups (DEV, FGAN-FfO & CELAR) and the experimental procedures used during the trial are presented along with a summary of the available datasets. Due to the large number of datasets only a select number were chosen for further in-depth analysis. These case studies were chosen using essentially two criteria: (1) interesting meteorological condition and (2) measurements were obtained by more then one group. The meteorological conditions for these case studies are presented along with comparisons of the measurements with the theoretical results obtained using both the PIRAM (CELAR) and L(W)WKD (DREV) models. Differences between the model predictions and some of the problems encountered are also discussed.

The pandemic of the novel coronavirus infection (COVID-19) has had an enormous impact on the education system. Higher educational institutions were forced to adapt to remote interaction with students and urgently switch to online learning. Currently, there are many educational platforms, among which one of the leading is the Californian Coursera service. In 2020, Kazan Federal University developed and published the first Coursera course on first aid — "Staying Alive! First Aid in Emergency". The purpose of the current study was to demonstrate the course results in one calendar year. We analyzed the general indicators of Coursera — the global online learning platform. We reviewed the course indicators from December 21, 2020, to December 21, 2021. The research assesses the advantages and disadvantages of using online courses in the medical education system. It was concluded that massive open online courses effectively teach theoretical disciplines. In case of implementation of applied courses, it is necessary to search and introduce new approaches for practical skill development. © 2022 Sklifosovsky Research Institute for Emergency Medicine.

In many online systems where recommendations are applied, interactions between a user and the system are usually organized into sessions. This paper studies how to model user preferences in session-based recommendation systems. Existing studies have either assumed that sessions are independent from each other and ignore long-term information from historical sessions, or treat the user's short-term preferences in a session as static, which cannot fully characterize user behavior in practical scenarios. Thus, we propose the recurrent memory network (RMN), which is an RNN-based framework that uni(cid:12)es the users' long-term and short-term preferences in session-based recommendation. The key component of the proposed RMN is preference memory, which stores a user's long-term interests. In addition, in the RMN, we design an intra-session memory reader and inter-session memory writer to facilitate explicit characterization of short-term (i.e., within a session) user preferences variation and long-term (i.e., cross-session) user preference transfer, respectively. The results obtained in extensive experiments on real-world datasets for movie and job recommendations demonstrate that the proposed RMN achieves substantial gains over state-of-the-art baselines.

When vic-dihydroxychlorins undergo a pinacol-pinacolone rearrangement, the migratory aptitudes of common porphyrin substituents follow the order: alkyl groups, propionate side chain, H > methyl group > acetate side chain. C-Alkylchlorins can be made by extremely short syntheses utilizing such rearrangement.


Applying the theory of semigroups of operators to evolution family and Banach contraction principle,we prove the existence and uniqueness of an(a) almost automorphic (pseudo almost automorphic) mild solution of the semilinear differential equation x′(t)=A(t)x(t)+f(t,x(t)) in Banach space under conditions.


Rotational transition in atom–diatom chemical reaction is theoretically studied. A new approximate theory (which we call IOS‐DW approximation) is proposed on the basis of the physical idea that rotational transition in reaction is induced by the following two different mechanisms: rotationally inelastic half collision in both initial and final arrangement channels, and coordinate transformation in the reaction zone. This theory gives a fairy compact expression for the state‐to‐state transition probability. Introducing the additional physically reasonable assumption that reaction (particle rearrangement) takes place in a spatially localized region, we have reduced this expression into a simpler analytical form which can explicitly give overall rotational state distribution in reaction. Numerical application was made to the H+H2 reaction and demonstrated its effectiveness for the simplicity. A further simplified most naive approximation, i.e., independent events approximation was also proposed and demonstra...


Hepatosplenic T-cell lymphoma (HSTCL) is a rare and aggressive extranodal T-cell lymphoma that comprises <5% of peripheral T-cell lymphomas. The majority of cases harbor the γδT-cell receptor (TCR), but recently, a few cases have been shown to express the αß TCR. Comparison of these two subtypes (αβ and γδ) shows similar clinicopathologic and cytogenetic features; however, due to the paucity of reported cases, it is not clear whether they are prognostically distinct entities. We report a case of αβ HSTCL with a rather unusual presentation of Coombs'-negative hemolytic anemia. Diagnosis proved challenging due to an unusual blastoid morphology with the absence of typical intrasinusoidal distribution of tumor cells in the bone marrow. This unique case adds to the growing list of this rare subtype of T-cell lymphomas, which warrant urgent attention due to the lack of effective treatment options and dismal prognosis.

Kahn's book2 is a timely intervention within current debates about the role of religion, politics, philosophy, and the public square. I was reading it as the Western world was once again reflecting (and in a not very coherent or analytical way) on the tenth anniversary of 9/11. As Kahn persuasively reminds us, international terrorism inextricably linked to religious imaginaries has forced liberal democracies and liberal intellectual disciplines to wake up to the real nature of politics: the themes of sovereign decision; the power of the exception rather than the bureaucratic norm; the lure of sacrifice and martyrdom; the will to act and choose authenticity rather than the use of reason or appeal to the norm. These are the seductive and destructive options that the international and religiously inspired terrorist offers us. I loved this book for its cool elegance and concision of thought. I also thought its use of Schmitt was strategic, unsensational, and judicious. Above all, I applaud the fact that this book doesn't seek to come to triumphant answers that re-assert the religious hegemony over the secularly liberal. Like Schmitt's original, it also deliberately fails to wrap up its arguments by choosing not to reach a definitive conclusion. "Any authentic political theory must be one that simply stops. There can be no conclusion: there is only a pointing beyond to that which theory cannot express"

We integrate age specific productivity differentials into a long-run neoclassical growth model for the Austrian economy with a highly disaggregated labor supply structure. We assume two life time productivity profiles reflecting either small or large hump-shaped productivity differentials and compute an average labor productivity index using three different aggregation functions: linear, Cobb-Douglas, and a nested Constant Elasticity of Substitution (CES). Model simulations with age specific productivity differentials are compared to a base scenario with uniform productivity over age groups. Depending on the aggregation function, the simulation results show only negligible or small negative effects on output and other macroeconomic key variables.


Objective: The aim of this study was to investigate the use of isolation in offices and private clinics in Belo Horizonte, it was observed: the type, procedures performed in isolation and the reason for their choices. In addition to those factors were also observed the duration of the dentists' training, the patients' economic class and the presence of an office assistant.
Method: The eligible sample consisted of active dentist in the south-center region of the town. The final sample of convenience was 115 professionals who answered to an instrument data collection with descriptive and objective questions. The results were analyzed descriptively and by Qui-Square test (p≤0,05).
Results: Among the dentist in the survey 55% were female, 63.5% were between 23 and 35 years old, 39% had less than five years of professional activity and 59% were specialists; 69% were from the central region and 31% from the south; 66% of the dentists have assistant in office. Patients were classified according to their economic class; class A (11%), B (30%), C (34%), D (16%) and E (9%). 82% of the dentists reported the use of some type of insulation, (36% relative, 28% absolute, and 36% both). The degree of the patients' acceptance to methods of moisture control was considered high, for 52% of the professionals. The main reason for choosing the absolute isolation was the control of infection (27%) and the relative was the practicality (24%). The rubber dam is mainly used in endodontics (38%) and the relative isolation is used in restorations (33%). The gender (p=0.6483), professional activity time (p=0.2576), training (p=0.0733) and presence of an office assistant (p=0.4127) haven't significant influence in the type of isolation choice.
Conclusion: The most of dentists reported using some type of isolation of the operative field and indicated that the main advantages are the biosafety, practicality and quality of procedures performed.


Background: Intraventricular haemorrhage (IVH) worsen the prognosis of Intracerebral hematoma (ICH). External Ventricular Drain (EVD) is inserted to reduce intracranial pressure that resulted from the progression of IVH. However, EVD is still an optional procedure because it is not always proven effective. This study was aimed to demonstrate prognostic factors of IVH and whether EVD insertion might improve the outcome. Methods: This cross-sectional retrospective study included IVH patients and concomitant ICH-IVH that required or not EVD in Cileungsi Hospital from January to December 2018. We made comparisons between EVD insertion group and non-EVD group based on sex, age, pulse pressure, Glasgow Coma Scale (GCS), bleeding volume, score of bleeding volume in ventricle lateral, third and fourth based on CT scan, Charlson Comorbid Index (CCI) and modified Rankin Scale (mRS). To determine factors contributing to the good prognosis of EVD, Spearman Correlation test was used with STATA 15 software. Results: 100 patients were diagnosed with ICH, five patients IVH, 16 patients ICH and IVH. Blood in the fourth ventricle made a significant difference between EVD and non-EVD groups in the concomitant ICHIVH group (p=0.035). GCS score (p=0.034) correlated significantly with the prognosis of concomitant ICHIVH patients that had EVD insertion with correlation coefficient 0.671. EVD did not improve the outcome in IVH patients nor patients with ICH-IVH. Conclusion: EVD did not improve the prognosis of spontaneous concomitant ICH-IVH or spontaneous IVH patients, but it still needs to be inserted in case of developing obstructive hydrocephalus that might be lethal.

Introduction: Patients with diabetes mellitus have a poorer outcome after acute coronary syndrome (ACS) than the general population.Objective of the study was to access the prognostic value of HbA1C in non-diabetic patients of acute coronary syndrome Material and Methods: This observational cross sectional study included 110 patients without diabetes mellitus who were admitted to the ICU with symptoms suggestive of ACS. The diagnosis of ACS was made on the basis of troponin T value, ECG and echocardiograph. Patients were stratified according to their HbA1c into two groups: Group 1 HbA1c <5.6 (36, 36%), group 2 HbA1c between 5.7 and 6.4 (64,64%). Main outcome measures were ECG changes, trop T value, RWMA and left ventricular ejection fraction (LVEF) on echo, along with the complications like heart failure and arrhythmias. Data was analyzed separately using multiple regression analysis Results: The mean age of patients was 58.67 years out of which 69% were males and 31% females. Of total, 28% were smokers, 33% were known to be hypertensive, 32% had dyslipidemia and BMI was ≥ 25 kg/ m 2


Abstract Lead zirconate titanate (PZT) rings are used extensively in various kinds of transducer applications. However, there are not many reports on the study of the vibration characteristics of a PZT ring, especially when the ring has a thickness t comparable to its wall thickness w. In this study, the vibration characteristics of a PZT ring with 12.7 mm outer diameter are modeled by a finite element analysis (FEM) as functions of w and t. The resonant frequencies and effective electromechanical coupling coefficient keff of the rings are measured by an impedance analyzer. The vibration displacements at the various resonances are measured by a laser vibrometer. Good agreements are found between the experimental results and the FEM simulations. Results from this study can be used to optimize the dimensions of PZT rings in transducer designs.


"Among the preliminary ship's evaluation steps, the global strength
of the ship's hull by design oblique wave's criteria is required from the classification society's construction rules. A 100000 tdw tanker is selected for evaluation, with two loading cases. The analysis is applied on a ship hull beam model, using own program software P_QSW, with three parameters non-linear equilibrium procedure. Significant oblique design waves are considered, corresponding to maritime operation cases. The global strength results at preliminary design steps are assessed by rules admissible values, so that the ship's global strength design restrictions are obtained."


Software-defined network (SDN) is a trend in network administration and monitoring. It promotes a new way of the various network activities, such as neighbor discovery, load balancing, routing, etc. All these services are initiated and organized by the programmable SDN controller, which is considered as the brain of the Software Defined Networking. This paper explores the best known controllers as OpenDaylight, Floodlight and Pox, and comparatively analyzes the performance characteristics of these based on parameters such as bandwidth usage, delay and jitter. Finally, the corresponding analysis results are discussed.


This research which provides a comparative analysis of child rearing attitudes and parental self-efficacy perception of mothers having preschool children was designed with relational screening model. The research's study group consists of 94 volunteer mothers whose children attended preschool education institutions selected by random sampling method in Istanbul in 2013-2014 academic years. In the study, Personal Information Form developed by researchers, Berkeley Parenting Self-Efficacy Scale–Preschool Form developed by Holloway (2005) and adapted into Turkish by Zembat and her colleagues, and Parental Attitude Research Instrument-PARI developed by Schaefer and Bell and adapted into Turkish by Le Comte and his colleagues in 1978 were used as data collection tools. According to the research results, it was determined that the values derived from "Overprotection" and "Strictness and Authoritarianism" subscales of PARI were significant predictors of values derived from "Maternal Strategy" subscale of Parenting Self-Efficacy Scale.


Viscous heat‐conducting fluid and anisotropic fluid space‐times admitting a special conformal Killing vector (SCKV) are studied and some general theorems concerning the inheritance of the symmetry associated with the SCKV are proved. In particular, for viscous fluid space‐times it is shown that (i) if the SCKV maps fluid flow lines into fluid flow lines, then all physical components of the energy‐momentum tensor inherit the SCKV symmetry; or (ii) if the Lie derivative along a SCKV of the shear viscosity term ησab is zero then, again, we have symmetry inheritance. All space‐times admitting a SCKV and satisfying the dominant energy condition are found. Apart from the vacuum pp‐wave solutions, which are the only vacuum solutions that can admit a SCKV, the energy‐momentum tensor associated with these space‐times is shown to admit at least one null eigenvector and can represent either a viscous fluid with heat conduction or an anisotropic fluid. No perfect fluid space‐times can admit a SCKV. These SCKV space‐t...


Since its publication in 1904–5, Max Weber's The Protestant Ethic and the Spirit of Capitalism has provided a paradigm for assessments of the attitudes to the profitable use of time among different branches of Christianity, emphasising the sanctification of work and thrifty care for time allegedly found in pronouncedly Protestant religious groups. This paper tests further assumptions made by Weber and his school by considering attitudes espoused within the two religious groups in early modern England which are often taken to epitomize the stereotypical extremes of Weberian hypotheses: on the one hand the Catholics, on the other the Quakers.

The purpose of this study was to investigate in differences in accuracy pattern as cognitive ability, ball pattern and section information of each ball pattern by analyzing the effect of section information of baseball pitching action on the accuracy of identifying ball patterns. Twenty-one university baseball player(over 8 years in career) and sixteen university students(1-3 years in career) who are joining in baseball club participated in the experiment as subjects. They were repeatedly assigned to the sessions of baseball pitching action, including session 1, session 2, session 3, session 4, and session 5. Baseball players and baseball club students observed randomly a model performing videotaped actions for 60 times for all ball patterns, 20 times for each ball pattern. Just after observing each task, subjects were required to tell researcher ball pattern. Researcher recorded it on checklist. The maximum score a subject could get for each task was 4, resulting in a total maximum score of 20 for each ball pattern. Calculated averaged-score for each session of each ball pattern was analyzed by three-way ANOVAs (2 groups × 3 ball patterns × 5 sessions) with repeated measures on the last two factors. In the analysis of the accuracy pattern for curve ball, the baseball player's accuracy identifying ball patterns showed significant increase from session 2 and 3. But for straight ball and slide ball, the difference between baseball players and baseball club students as increasing sessions didn't show. Taken together, these results suggest that the accuracy of identifying ball patterns can be affected by both performer's cognitive ability, using pre-information effectively, and the characteristics of ball patterns and that cognitive ability as well as physical motor activity may also contribute to the improvement of motor performance.


Given the interdisciplinary nature of the risk analysis methods, its expanded applicability in various fields and the complexity of causes and risk factors, we propose for evaluation a number of analytical methods used in intelligence analysis which can prove to be useful in risk analysis and assessment: scenario analysis, SWOT analysis, the analysis of competing hypotheses and Red Team analysis.


This work presents a new formula to calculate the surface tension of alcohols. As a first step, an analysis of the available data of the surface tension for alcohols was made. A total of 1643 data were collected for n-alcohols, aromatic alcohols, cycloaliphatic alcohols, 2-alkanols, and methyl alkanols. The data were then analyzed through a factor analysis approach. The factor analysis, combined with physical considerations, allowed to regress the experimental data with a scaled equation that is very simple to employ. The same physical parameters considered in the scaled equation were also adopted as input parameters in a multi-layer perceptron neural network, to predict the surface tension of alcohols. The proposed multilayer perceptron has one hidden layer with 30 neurons, determined according to the constructive approach. The proposed model was trained, validated, and tested for the set of collected data, showing that the accuracy of the neural network model is very high.


The paternity of a child may be disputed either when the child is born in wedlock and the husband denies paternity or when the child is born out of wedlock and the man named as the father denies paternity. There is great variation across cultures in beliefs about paternity, but cross-culturally, paternity confidence is positively associated with men's involvement with children and with investment or inheritance from paternal kin. The study aims to focus on the role of DNA as powerful technology in disputed paternity and to determine the different environmental factors that predisposes to deny children. DNA typing of 15 short tandem repeat (STR) loci included in the AmpFl STR Identifiler TM PCR amplification kit (Applied Biosystems), was carried out on paternity cases arriving to Egyptian Forensic Medicine Authority (EFMA) Medical laboratory with the use of questionnaire, this study was done during the period of one year, 48 cases fulfilled the criteria of this study with total 153 individuals. Results showed that 23 of studied cases were inclusion cases (the alleged fathers "AF" are the true fathers) , 23 of studied cases were exclusion cases (the AF are not the true fathers) while the remaining two cases showed inclusion and exclusion within the same case.


The lirst article, NChanging from Production 10 Quality: Application of the Situolionolleadefship and Tronstheoreticol Change Models" by Richard A Grover and H, Fred Wolker of the University of Southern Moine, focuses on leodership and ib role in determining the success or failure of qllOlity management efforts. The authors integrate concepts from the Transtheoretical Model ofChange arld the Sitvotionolleodership Model to develop a framework for assessing the readiness of followers for some of the changes associated with qllOlity management, as well as prescribing appropriate leadership styles for meeting the needs of lallowers in each of the readiness levels, For example, in levell, the followers have no interest in and noability tc perform the tosks associated with quality management. The appropriate style of leadership is described as the Mtell ingMstyle, which is highly structured and focuses on providirlg information and instruction. In contrast, followers in level 2 are willing and eagertoembroce quality management botleek the skills tocarry itouteffectively. For this level, the · sell irlg· leadership style is appropriate, combining direction with on invitation for two-way dialogue. This article provides a useful set of guidelines for feeders to use in focilitating each stage of the trcnsjcrmcbcn to quality.

High SSC related to Dongjiakou Harbor construction was observed during June 2010 to August 2013. The adjacent Mytilus edulis aquaculture waters with area of 11.13 km2, 15.48 km2, and 24.27 km2 were affected by the high SSC retrieved from remote sensing SSC on 24 April 2011, 21 September 2011, and 10 January 2013. The aquaculture rope and Mytilus edulis were full of sediment during the in-situ survey on 5 March 2013.


Simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] inhibited photosynthesis 50% at concentrations of 1.1 μM for Spirogyra jurgensii (Kutz), 3.0 μM for Pithophora oedogonia (Mont.) Wittr., and 3.8 μM for Cladophora glomerata (L.) Kutz. Photosynthesis of Ankistrodesmus braunii (Brun.), a nonfilamentous species, was inhibited the same amount by 4.7 μM simazine. The filamentous algal species had significant reductions in growth but no other phytotoxic symptoms when exposed to 5 μM simazine at light intensities of 100 μE·m–2·s–1 and below. Algicidal effects did occur at a light intensity of 400 μE·m–2·s–1 and were most severe in Spirogyra. The relationship between light intensity and simazine toxicity indicates algicidal effectiveness on these filamentous algae will be limited in habitats where light is reduced by turbidity, depth, or self-shading.


An experiment examined intended and unintended effects of print comparative political advertising on political decision-making, voting preferences, and situational election involvement. Results suggested that comparative advertising reduces targeted-candidate voting preferences while avoiding most forms of voter backlash. Voter backlash was evidenced, however, in participants' perceptions that the sponsoring candidate was mean-spirited. Comparative advertising significantly increased participants' situational election involvement.


Objective: The aim of this study was to investigate the influence of depression on the structural changes of left ventricular (LV) myocardium in patients with arterial hypertension (AH). Design and method: In 120 patients (87 males), aged from 29 to 62 years, with newly diagnosed or untreated mild to moderate AH, by the questionnaire of Hamilton (Hospital Anxiety Depression Scale – HADS), were assessed the presence and expressiveness of depression. Total index in the range of 8–10 points considered as subclinical anxiety/depression, more than 10 points – symptomatic anxiety/depression. All patients were underwent echocardiography in the sectoral mode («Sonos 5500», «Hewlett Packard»), structural and morphometric parameters were estimated by Teincholz method. LV mass (LVM) was calculated by the formula of Devereux R., et al. LVM index (LVMI) was calculated as the ratio of LVM to body surface area. The criteria for left ventricular hypertrophy (LVH) was considered for men >125 g/m2 for women – >110 g/m2. For data collection and statistical analysis «SPSS v17.0» program was used. To evaluate intergroup differences (M ± m) parametric unpaired Student's t-test was used. To determine the linear relationship of quantitative characters, Pearson's correlation coefficient was used. Fisher's exact test was used when comparing the frequency of adverse changes. The differences at p < 0.05 were considered as statistically significant. Results: Patients with AH were divided into two groups: I group – 34 patients with clinically severe depressive syndrome and group II – 86 patients without significant depressive signs. The groups were matched for age, duration of AH, body mass index, the clinical values of systolic and diastolic blood pressure. In patients with clinically severe depressive syndrome revealed significantly higher LVMI (p < 0.05), as well as the high incidence of LVH (70 and 51% respectively, p < 0.05). In Group I revealed significant correlation between expressiveness of depression and ventricular septal thickness, LV posterior wall, regardless of the degree of severity AH. Conclusions: A significant relationship was revealed between the expressiveness of depression and structural changes in the LV in patients with AH. Obviously, long-term emotional stress is the additive cause of LVH in patients with AH.


The rubbers in hydraulic packer can swell up and contact with the casing wall under hydraulic action. In this way, the annular layers can be separated. The process of compressing distortion and contact with casing wall belongs to a ternary nonlinear problem. The pressure distribution rules of rubbers in contact with casing wall were analyzed using the numerical simulation method, and the effects of friction coefficient between rubbers and casing wall on the contact pressure distribution were analyzed. The results show that the contact pressure on the top of rubber is the lowest, and the contact pressure at the bottom of rubber is the highest. The friction coefficient has a great influence on the contact pressure distribution on the surface of rubber. The contact pressure of rubber will fall down with the friction coefficient increasing.


Is the control perception a protection factor against emotional distress in HIV+ people? The Perceived Control in the HIV infection has been investigated in different contexts. Most of the studies pointed out that the perceived control could be adaptive facilitating people to adjust to illness and moderating distress. The relationship between perceived control and-emotional distress was investigated in a sample of 100 HIV+ consecutive patients, from the HIV Unit of the University Hospital "La Paz". Results indicate that the level of emotional distress changes according to illness stage, and that perceived control is inversely associated to the level of emotional distress, being the first variable predictor of the second.
