In this paper I identify various ways that abduction could function as a "logic of discovery". I delineate two basic interpretations concerning C. S. Peirce's abduction, that is, inferential and instinctual, and how they fit to N. R. Hanson's research programme for conceptualizing the area of discovery. I maintain that these perspectives should be broadened to take into account those ideas which have been emphasized in the recent approaches of distributed cognition, given the aim is to understand actual processes of discovery. This broadened approach is in many ways akin to Peirce's overall philosophy but it means that basic conceptions of abduction have to be embedded, to be a part of socially, materially, culturally, and temporally distributed cognition. I analyze briefly consequences of distributed cognition for conceptualizing abductive processes of discovery.


While it is widely accepted that adequate food supplies and a healthy population are necessary for national development, there has been considerable controversy over how nutrition concerns should be integrated into the development process. The issues debated are many, and include the nature and determinants of nutrition programmes as well as optimal solutions. The wide divergence of opinion on these issues is, no doubt, due in part to the divergent backgrounds of professionals in the field. While information is increasingly available on the relative merits of various nutrition-related policies and programmes, few data are available on the ideological profiles of planners and professionals involved with nutritionrelated activities in developing countries. There is little doubt that their attitudes affect their decisions for solving nutrition problems. The purpose of this study was to determine the attitudes of influential planners and professionals toward nutrition-related policies and issues in a developing country, Morocco.


In order to avoid the practical application problems, abnormal data insufficiency and unavailability, and solve the difficulty of calculating embed dimension and time tag before calculating Lyapunov exponent, an one-class Bearings fault detection model based on genetic algorithm and Lyapunov exponent spectrum is proposed in this paper. The normal training samples are used to decide reconstructed phase space. Then the signals with different conditions will be projected into RPS, the Lyapunov exponent is calculated which is classified as features. The optimum decision threshold values are determined by Genetic Algorithm. The results show that Lyapunov exponent for fault detection is more efficient than for fault diagnosis. In experiment, the performance of detector with largest Lyapunov exponent and Lyapunov exponent spectrum entropy is compared .The results evaluates the effectiveness of the proposed approach. This proposed approach is compared against MLP and other detection techniques. The results show the relative effectiveness of the proposed classifiers in detection of the bearing condition with some concluding remarks.


Understanding the impact of project complexity on the mega construction project success will help improve the efficiency of project management. However, the influencing mechanism of project complexity on project success has not been clearly depicted. This paper aims to divide project complexity and project success into five dimensions, trying to explore the impact of different complexity combinations on mega construction project success.,This study applies the qualitative comparative analysis (QCA) method to find out the impact of the combinations of different project complexities on the every dimension of mega construction project success. First, 21 cases were interviewed and scored in five categories of project complexities and five aspects of project success. Second, with the QCA program, the combinations of different project complexities influencing every aspect of mega construction project success was obtained.,This research found that high organizational complexity or a combination of high environmental complexity and goal complexity can lead to serious schedule delays of mega construction projects, high technological complexity and goal complexity are important reasons for cost overrun, high technological complexity or a combination of high environmental complexity and low organizational complexity usually lead to low quality of mega construction projects, high goal complexity and cultural complexity are important factors affecting the key stakeholders' satisfaction and high technological complexity and environmental complexity are the reasons for the poor sustainability of mega construction projects.,This study clearly reveals the influencing mechanism of project complexity on mega construction project success, which can help the project managers to understand and assess the complexity of mega construction projects and accurately predict their negative impacts on the mega construction projects.


This paper presents an investigation on modal simulation of turbocharger impeller with considering fluid-solid interaction. To demonstrate how the fluid-solid interaction affects modal parameters of the turbocharger impeller, a fluid field model of the impeller was established based on the theory of turbulence flow. Then the fluid grid was discretized and the fluid boundary condition was loaded. After obtaining the velocity and pressure distribution of the inner flow filed of the impeller by simulations, the distributed pressure was loaded onto the structure surface of the impeller to calculate the modal parameters of the impeller. Simulation results show that the solid-fluid coupling field has an influence mainly on the modal frequencies of the impeller, and less on its modal shapes. The simulation results are very useful for designing turbocharger impeller.


Distributed power converters represent a technical solution to improve the performance of large or utility-scale photovoltaic (PV) plants. Unfortunately, evaluation of the yield obtained in large PV fields by using distributed converters is a difficult task because of recurring partial unavailability, inaccuracy of power analyzers, operating constraints imposed by the Power Plant Controller and so on. To overcome such issues in real operating scenarios, a new modeling strategy has been introduced and validated in terms of computational complexity and accuracy. This approach is based on the state-space averaging technique which is applied to large PV plants with multiple conversion stages by performing some elaborations in order to get a final integrated model. The new modeling strategy has been tested in MatLab Simulink environment using data coming from a 300 MW PV plant located in Brazil representing the case study of this work. In this plant, one subfield is equipped with central inverters while another is with string inverters. The proposed model, whose accuracy is in the range from 2.2 to 2.7% with respect to the measured energy, effectively supports data analysis leading to a consistent performance assessment for the distributed conversion system. Final results highlight that string inverters ensure a gain of about 2% in terms of produced energy.

INTRODUCTION
Morbidity due to motor vehicle accidents was analysed in a descriptive study based on reports of hospitals with the objective to characterize their victims, types of injuries, and the health care provided.

METHODS
The study was carried out in two municipal hospitals of Rio de Janeiro, Brazil. Motor vehicle accidents were defined as a run over, a collision, and "other traffic accidents". Data was collected from cases seen in May (Hospital 1) and June (Hospital 2) of 1996 by 7 teams that alternated in shifts of 12 hours, covering the collection 24 hours per day. The events were classified according to the victim or, when it was impossible, to the person who helped them or accompanied them to the hospital.

RESULTS
In the study period, 320 cases were seen in Hospital 1 and 290 in Hospital 2. Most of the victims were men (69.3%) in both of hospitals and the most affected group was young adults between 20 to 39 years (60.5% in Hospital 1 and 47.5% in Hospital 2). Of all 610 cases, the main cause of injury was being run over (49.3%), followed by collisions (35.6%), and "other traffic accidents" (15.1%).

CONCLUSIONS
The analysis of the cases distributions and the type of care required corroborates with the need of a better organization of hospital care teams, more completeness of hospital reports and emphasis on some aspects in prevention campaigns.


This paper proposes an antenna design concept to achieve a multi-reconfigurable band-notch antenna by using a set of microswitches. The proposed idea was proved by the design of the coplanar waveguide (CPW)-fed slot antenna. The sample design gives a wideband antenna the impedance bandwidth of which covers the frequency ranged from 1.9 GHz to 6.55 GHz. The antenna could be configured to work either in single-band mode or in one of the defined dual-band modes.


A body of research has revealed that low self-control is one of the strongest and most consistent predictors of antisocial behaviors. As a result, there is great interest in identifying the factors that cause variation in levels of self-control. Much of this work has centered on identifying the effects that social factors, such as parental socialization, have on self-control. More recently, however, there has been research revealing that levels of self-control are scripted by genetic factors as well as environmental factors. The current study examines whether a polymorphism (5HTTLPR) in the serotonin transporter gene and exposure to delinquent peers are associated with levels of self-control. Analysis of the National Longitudinal Study of Adolescent Health indicates that the 5HTTLPR polymorphism interacted with a measure of delinquent peer affiliation to predict variation in self-control during adolescence and adulthood. Implications for theories of crime causation are discussed.


W HEN I TAUGHT FIRST, SECOND, and third grade science in public school, each class contained a diverse set of children. In saying this I mean the sorts of diversity that teachers confront, differences in ability, affect, personality, gender, race, and class. Each child was also different in that each came to my classes as a little package of cultural experience. Each child came from a particular social/ cultural group of which their families were members (e.g., "Korean-American-Baptist" or "militant-leftiststudent" or "midwestern-farmer-from-a-small-town") and they were representatives of that group-they brought their cultural heritage to my class and often shared it with others who were different.

Xanthomonas campestris pv. campestris (Xcc) is the causal agent of black rot, a highly destructive disease that affects all brassicas. This work aimed to study the interaction Xcc–Brassica oleracea using an in vivo system in an attempt to identify proteins involved in pathogenicity. We used label‐free shotgun 2D‐nanoUPLC/MSE to analyze Xcc proteins in three conditions: in the interaction with susceptible (REK) and resistant (REU) plants and in culture medium (control condition). A model of Xcc–susceptible host interaction is proposed and shows that Xcc increases the abundance of several crucial proteins for infection and cell protection. In this study, we also confirmed the differential expression by qPCR analysis of selected genes. This is the first report showing a large‐scale identification of proteins in an in vivo host plant condition. Considering that most studies involving phytopathogens are in vitro (growth in culture medium or in plant extract), this work contributes with relevant information related to the plant–pathogen interaction in planta.


Bridge scour is a complicated process involving the interactions between flow and bridge piers and between flow and bed sediment. The existing numerical studies often coupled different sediment transport models to a turbulence flow model to simulate the scour process. The influence of the turbulence fluctuation and the lift force are not incorporated in the traditional sediment models. In this paper, the authors proposed a framework to evaluate the performances of different sediment transport models. Specifically, the sediment transport equations are given an in-depth study and a new modification method to the sediment models to include the above mentioned influences was proposed based on a comprehensive review. In this framework, the flow domain will be solved using a URANS approach with a k-ω turbulence closure model; the sediment transport models (traditional and modified) will be coupled with the flow domain using the arbitrary Lagrangian-Eulerian method.


Learning provides the basis for fostering transitions toward adaptive comanagement. Understanding the ways in which arenas for collaboration and learning are created, and the outcomes of these processes in different contexts, is therefore crucial. This paper presents the results of an experimental research process that identified a small set of key variables that influence effective collaboration and learning, and tested a methodology for monitoring these in a collaborative way in three case studies in South Africa. The small set of key variables tested in this study was sensitive enough to register change over a period of 18 months. Results suggest that the background conditions necessary for social learning can be externally managed during an initiative, with positive outcomes for collaboration and learning. Monitoring outcomes suggest that for learning to be effective, a balance needs to be sought between maintaining key individuals within the system, preventing rigidity and vulnerability when this is achieved, and encouraging active participation within communities of practice. Effective facilitation by an 'honest broker' is one of the ways in which this can be achieved. The results point to an over simplification in the rhetoric that currently surrounds the learning outcomes of multilevel networks, and challenges the idea that democratic structures are necessarily important for effective natural resource management at the community level.

This article studies how the books 12 to 14 of the Ovide Moralise carry an important political message and intend to be a kind of principis regimen. Recent studies on the translation of Ovidian Metamorphosis at the beginning of the 14th century haven't taken into account this opinion, concentrating on the predication book hypothesis. In the books 12 to 14 where the Trojan myth and the narration of the new city foundation, Rome are very important. Clergy and rhetoric competence of the characters, especially of Ulysses, prophetic voices (Sybille and Enee), apocalyptic discourses and power imaginary (Moses and mystical wedding) induce a political interpretation. In this way, the analysis of the translation, of the allegorical interpretations and the organization of the manuscript of Rouen BM 0.4 (iconography and structure of the text) enlarge the perspective suggesting a curial and ecclesiological reception


Providing realistic road traffic in virtual environments is a challenging problem. It implies handling behavioral and physical aspects of autonomous vehicles, so as to immerse the driver in a realistic simulated environment and provide perceptually valid results. SCANeR© II, developed initially by Renault and today by Oktal, integrates a traffic module which has been developed during the last 10 years. As industrial and academic end-users are becoming more and more exigent about traffic realism, new perceptual and behavioral driver-vehicle behavior models will constitute the basis of an enhanced traffic module for a new version of SCANeR©. In this paper the authors first present the traffic simulation module implemented in SCANeR© II. Existing features of the current perception-decision-action model, providing autonomous vehicles with realistic interactions between each other, as well as intrinsic limitations and difficulties are discussed. The capacity to describe adequately the environment, with geometric, topologic and semantic data, is an important basis for the animation of the autonomous traffic. SCANeR© II currently uses a two-layer data format for the description of the environment, which is based on a discontinuous logical description mapped on a continuous 3D graphical database. The authors present here a new unified data format with a new logical description. The authors will show how the integration of this new data format increases the realism of the behavior of the autonomous vehicles, by reducing conflicts that could appear between graphical and logical layers. It provides also a solid basis to major improvements of the current traffic module, like the introduction of realistic behavioral parameters in the decision model, allowing to take into account various perceptual variables, such as Time To Collision or Time to Lane Crossing, in the execution of the different vehicles maneuvers.


should teach. With the exception of Rex Walford, this book is written by academics at some remove from schools and the contemporary teaching of geography. That was not altogether true of 'Frontiers' which surveyed geography in the universities, training colleges, technical colleges and schools. What we now need is for those active in school teaching, or in training teachers of geography, to develop the most profit able themes in this book in an operational way. Allied with a much needed atten tion to the image of our subject, that could move us on more quickly towards a future geography of relevance, value and high quality. One of the problems the subject faces is that many of us do not feel at all certain that our geographical educationaUsts have such a book in them. 1 hope they prove us wrong.

Introduction Elemental imaging of several elements simultaneously and with detection limits in the ppb range is achieved by synchrotron-based X-ray fluorescence microscopy, also often referred to as micro-X-ray fluorescence (MXRF). This has been shown, for example, by imaging Cu and U distribution in contaminated sediments [1] and P, Ca, and Zn distribution imaging of single cells and mitochondria [2]. A review on environmental application can be found in reference [3]. XRF micro-probes are available at synchrotrons all around the world and allow for 2D imaging with spatial resolution from several micrometers down to the nanometer range (30–100 nm); the latter mainly at thirdgeneration synchrotrons. X-ray fluorescence (XRF). Interaction of X-rays with matter is in general dominated by the absorption of photons to generate photoelectrons. Because of the relatively high energy of X-ray photons, core shell electrons are often targeted by this process. Relaxation of the core hole occurs by a transition of an outer shell electron and emission of the transition energy as either an Auger electron or a photon, usually in the X-ray energy range. The emitted fluorescent X-ray photon is characteristic of the excited element. This process is the basis for qualitative and quantitative determination of the elements present in the specimen, as well as XRF microscopy. As in other types of microscopy, MXRF can be performed in scanning mode or in full-field mode (Figure 1). Full-field MXRF. In the full-field MXRF mode, the full sample is illuminated by the X rays from the source, and the fluorescence is guided by an optic to the fluorescence array detector. This is illustrated in Figure 1a. Horizontal and vertical slit systems can be used to shape the beam. However, most MXRF setups operate in scanning mode, which means the sample is moved through a focused primary X-ray beam that excites the fluorescent X rays. A single element fluorescence detector can be used. This is illustrated in Figure 1b. The scanning mode comes with disadvantages regarding in situ applications where the sample must remain fairly static or where the sample is brittle or in other ways sensitive to movements. Here full-field MXRF is advantageous. An example is the imaging of elemental distributions in droplets (10–20 μL containing Mn, Ni, Cu, and Sc) while drying. This is shown in Figure 2. The droplets were allowed to dry undisturbed while the elemental information was recorded. Full-field MXRF allows for fast imaging of large areas (for example, 12×12 mm2 at 1,000 frames per second and 264×264 pixels) and therefore simultaneous detection of elemental changes over the entire field of view, which can be important for certain in situ applications. However, the detectability of each element will depend on the fluorescence yield of the element and the total counts acquired. Thus, the recording frequency will be limited by the need to acquire enough counts for detecting specific elements. Full-field MXRF also allows fast 3D elemental imaging by taking images at different depths of the sample using a sheet beam.


In this study, the mechanical properties of different CFST column shapes, including circular, rectangular, square, square with rounded corners, and triangular, are all analyzed and compared using the ANSYS R2 2021 software. Total deformation, equivalent stress in concrete and steel, equivalent elastic strain in concrete and steel, and mechanical characteristics of the various CFST column shapes are also compared. axial load as well as the highest load that CFST columns can support. Comparing the circular model to other models, it was discovered that it is more resilient to stress and strain and deforms less.13.648% total deformation and decreases in stress and strain of 41.66%, 25.93%, 42.06%, and 24.99% for concrete and steel, respectively. Key words: steel tubes with concrete filling, deformation, maximum load, stress-strain, and ANSYS software.


WIlER, GERALD A. Conservation of Different Quantities among Preschool Children. CHmD DEVELOPMENT, 1974, 45, 839-842. Although several studies have indicated that preschoolers cannot conserve number, even if tested on small quantities, in this study it was demonstrated that preschoolers show a remarkable degree of conservation when tested with small enough quantities. The results also suggest that the child's understanding of small quantities might possibly play a role in the development of conservation of larger quantities.


A one-dimensional Co(II) complex [Co(BTE)2(NCS)2]n (1) (BTE = 1,1'-(2,2'-oxybis(ethane-2,1-diyl))bis(1H-1,2,4-triazole)) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a one-dimensional chain polymer with a Co—Co separation of 8.830(2) Å. The adjacent 1D chain are linked by the π—π interaction between the triazole rings to form a two-dimensional layer parallel to the (0 0 1) crystal planes. Moreover, the thermal stability of the title complex is briefly investigated.


In this paper, the solution of the problem of identification of thermal properties of investigated multi-layer structure is presented. In order of that, artificial neural network was used to find the set of thermal properties for which the complex contrast characteric derived fits the best to the one evaluated basing upon experimenatal data.


Softwood and hardwood lumber has, for the most part, largely been dried using empirically derived schedules, i.e., on a trial and error basis. These schedules are applied to the kiln through manual-set controller-recorders, which are non-reactive. That is, they do not respond automatically, schedule wise, to changes in the drying characteristics of the charge. Such schedules represent a combination of discrete changes in dry and wet-bulb temperatures and can be termed step-form type schedules. In hardwood drying where the use of kiln samples is much more common, the schedules might be viewed as semi-reactive since the predetermined step-form schedules are changed in response to the periodic measurement of the kiln sample's moisture content. In recent years there has been an increased interest in using schedules that continually change with respect to time or continuous change schedules. The ideal case would consist of a fully reactive control system capable of sensing the charge drying rate and/or quality and which would change the schedule in a continuous fashion. The various types of possible lumber drying schedules are summarized in Table 1. Cam controllers which are presently used in a number of kilns are non-reactive but permit the schedule to be changed on a continuous basis. A problem that we have observed when operations first begin using cam controllers and which is true for any other continuous change control system is how to develop a suitable schedule.


Over the past two decades, the Federal Aviation Administration (FAA) and the aircraft engine industry (organized through the Rotor Integrity Sub-Committee (RISC) of the Aerospace Industries Association) have been developing enhanced life management methods to address the rare but significant threats posed by undetected material or manufacturing anomalies in high-energy rotating components of gas turbine engines. This collaborative effort has led to the release of several FAA advisory circulars providing guidance for the use of probabilistic damage tolerance methods as a supplement to traditional safe-life methods. The most recent such document is Advisory Circular (AC) 33.70-2 on "Damage Tolerance of Hole Features in High-Energy Turbine Rotors." In parallel with this effort, the FAA has also been funding research and development activities to develop the technology and tools necessary to implement the new methods, including a series of grants led by Southwest Research Institute® (SwRI®). The most significant outcome of these grants is a probabilistic damage tolerance computer code called DARWIN® (Design Assessment of Reliability With INspection). DARWIN integrates finite element models and stress analysis results, fracture mechanics models, material anomaly data, probability of crack detection, and uncertain inspection schedules with a user-friendly graphical user interface (GUI) to determine the probability of fracture of a rotor disk as a function of operating cycles with and without inspection. This paper provides an overview of new DARWIN models and features that directly support implementation of the new AC on hole features. The paper also simultaneously provides an overview of the AC methodology itself. Component geometry and stresses are addressed through an interface with commercial three-dimensional finite element (FE) models, including management of multiple load steps and multiple missions. Calculations of fatigue crack growth (FCG) life employ a unique interface with the FE models, sophisticated new stress intensity factor solutions for typical crack geometries at holes, shakedown modules, a menu of common FCG equations, and algorithms to address the effects of varying temperatures on crack growth rates. The primary random variables are based on the default anomaly distributions and probability-of-detection (POD) curves provided directly in the AC. Fracture risk is computed on a per-feature basis using one of several available computational methods including importance sampling, response surface, and Monte Carlo simulation. The approach is illustrated for risk prediction of a representative gas turbine engine disk. The results can be used to gain a better understanding of the AC and how the problem is solved using the probabilistic damage tolerance framework provided in DARWIN.Copyright © 2012 by ASME


The number of phase wraps in an image can be either reduced, or completely eliminated, by transforming the image into the frequency domain using a Fourier transform, and then shifting the spectrum towards the origin. After this, the spectrum is transformed back to the spatial domain using the inverse Fourier transform and finally the phase is extracted using the arctangent function. However, it is a common concern that the spectrum can be shifted only by an integer number, meaning that the phase wrap reduction is often not optimal. In this paper we propose an algorithm than enables the spectrum to be frequency shifted by a rational number. The principle of the proposed method is confirmed both by using an initial computer simulation and is subsequently validated experimentally on real fringe patterns. The technique may offer in some cases the prospects of removing the necessity for a phase unwrapping process altogether and/or speeding up the phase unwrapping process. This may be beneficial in terms of potential increases in signal recovery robustness and also for use in time-critical applications.

8991846 Background and ObjectiveS: The field of training and learning of work and technology is one of the eleven areas included in the national curriculum and includes the acquisition of practical skills for a productive life and the acquisition of competencies related to technology related sciences. One of the main foundations of curriculum reform in the 20th century is the trend of increasing technology education. These competencies are essential for technological education and healthy life in the cyberspace, as well as readiness to enter professions and jobs in various economic and social sectors. According to Islamic teachings, work and employment have educational values and through work, human polishes their existential personality, establishes their identity and prepares the ground for their existential development and the possibility of earning a lawful livelihood and provides to meet the needs of the community. Another step in developing minimum skills is teaching design and technology in schools. Technology education, work and skills training will lead to personal development, increase productivity, participation in social and economic life, reduce poverty, and increase income and development. It should be noted that pathology is a systematic process of data collection in order to interact effectively and usefully in order to solve problems, challenges, pressures and environmental constraints in society. In fact, the pathology of the work and technology curriculum can help in determining hindrances, weaknesses and strengths, and challenges and opportunities and proposing suitable strategies. Also, warranting the quality in work and technology education is amongst the top priorities to develop the related curriculum, job selection and applied disciplines. If the quality of the curriculum of work and technology is not examined systematically, the entrepreneurship that is the top need of the country is not developed. The purpose of this study is to identify the damages in the implementation of the technology curriculum. Methods: This research is qualitative and phenomenological. This research was performed using a


Abstract The specificity of amino acid consumption by Porphyromonas gingivalis , well known as an important pathogen of adult periodontitis, is described. P. gingivalis is an asaccharolytic, black-pigmented and gram-negative anaerobe and produces several types of proteases including cysteine proteases such as arg-gingipain and trypsin-like enzyme. This suggests that arginine is a possible energy source for its growth. When P. gingivalis was grown anaerobically in brain–heart infusion broth, several free amino acids such as lysine, glycine and glutamic acid increased in the culture supernatant with the bacterial growth; but free arginine increased first and then started to decrease after the early log phase. Citrulline and ornithine increased to late log phase in contrast to the decrease of arginine. The total arginine in the medium decreased steadily with the growth of P. gingivalis . In relation to the arginine consumption, cell extracts of P. gingivalis clearly demonstrated enzyme activities for the arginine deiminase pathway and adenosine triphosphate production. The arginine deiminase pathway was also presumed from the presence of putative homologue corresponding to the other bacterial arginine deiminase pathway relating enzymes in the unfinished P. gingivalis W83 genome. These results suggest that P. gingivalis catabolizes arginine which is released from proteins and/or peptides by several types of proteases, and obtains energy through the arginine deiminase pathway.


Polyelectrolyte complexes are ionic hydrogels formed by the coreaction of two oppositely charged, strongly ionized polyelectrolytes. While insoluble in simple solvents and infusible, these polymers can be fabricated into membranes, fibers, and other shaped articles by casting from ternary solvents. Homogeneous membranes are optically clear, amorphous structures in which the equilibrium gel water content can be controllably varied from ca. 30–90%. The net ion-exchange capacity of the membrane can be varied from zero to ca. 2.0 meq/g, either cationic or anionic. Homogeneous membranes are characterized by unusually high water and gas permeabilities and permeabilities to water and soluble solutes which can be controlled by adjustment of gel water content and ion-exchange capacity. Anisotropic membranes can also be prepared which are high flux molecular ultrafilters for solutes as small as sucrose. The anisotropic membranes have found widespread use in biology for fractionation, concentration, and purification of biopolymers. Homogeneous membranes show promise as analogues for biological membranes. A number of applications are being evaluated in medicine and surgery. These include: vascular grafts, antithrom-bogenic coatings for plastic prostheses, contact lenses, corneal implants, and surgical adhesives. In addition, polyelectrolyte complex membranes are showing considerable promise for artificial kidneys and blood oxygenators.


At the moment, a small amount of research has been carried out in the Russian literature devoted to the analysis of the ideological foundations and concepts of the development of the Polish eastern policy. The purpose of this article is to study the key ideas of the eastern policy of the Polish state and their further evolution before the emergence of the Eastern Partnership in 2008. As sources, the author used materials in Russian, English and Polish, which made it possible to conduct a comprehensive analysis of the eastern policy of the Polish state. The author of the article concludes that the Polish eastern policy has deep historical roots and is based on a fundamental ideological basis. The article provides an analysis of the «Jagiellonian» and «Piast» concepts of the development of the Polish state. The key features of Poland's foreign policy strategy in the East, which are relevant nowadays, are associated with the ideas of Józef Piłsudski and Roman Dmowski - the idea of messianism and a civilizational mission. Today there is a revival of old concepts, the so-called «Prometheism 2.0». Studying the historical foundations of Polish politics will help in analyzing Poland's current foreign policy strategy.


Objective To know the status and existing problems of the implementation of essential drugs system in community health service centers in Gulou district of Fuzhou city,and to put forward a reference to improve.Methods Questionnaire survey and the monitoring tables were filled in by community health service centers.Results The community health service centers that were investigated had equipped with and used the essential drugs in varying degrees,and the essential drugs retail price and per capita medical expense had fallen.But the outpatient amounts and the constituent ratios of compensatory channels had changed little,and the variety of the essential drugs that these community health service centers equipped was still at low level in general.Conclusions The essential drugs system zero cost-plus markup policy had different impacts on these community health service centers.The government should build the dynamic selection and update mechanism for essential drugs list,and consummate perfect supporting systems,such as bidding and distribution system,multichannel compensation system,supervision and evaluation system to improve the essential drugs system continuously.


lIgObjective.l/Ig To determine maternal health service utilisation by
rural women. The findings presented here are part of a
household survey, which studied the effect of accessibility on
maternal and child health (MCH) service utilisation and
MCH status.
lbrglIgDesign.l/Ig An analytical cross-sectional household survey.
lbrglIgSetting.l/Ig Ubombo district, rural KwaZulu-Natal, South Africa.
lbrglIgParticipants.l/Ig Six hundred and forty-six mothers/caregivers of
children aged 12 - 23 months were interviewed during June -
August 1998 using a structured questionnaire. Outcome measures.l/Ig These were: (i) the proportion of women
who attended an antenatal care (ANC) clinic during
pregnancy with the index child; (ii) the proportion of mothers
who had supervised deliveries at the health facilities; and
(iii) current practice, source and method of family planning.
lbrglIgResults.l/Ig Of the 622 mothers interviewed, 99.8% had attended
an ANC clinic at least once during pregnancy. More than 80%
had obtained ANC from fixed and mobile clinics. Most
women (91.2%) had presented early for the first time at an
ANC clinic, and 78% had attended five or more times. The
majority of women (77.2%) had health facility deliveries.
Although 88% of the women reported that they were sexually
active, only 46% were currently practising family planning.
lbrglIgConclusions.l/Ig Utilisation of ANC and delivery services has
improved to a level above the targets set for the years 1998
and 2000. The low utilisation of family planning services is
worrying, considering the increasing prevalence of HIV in
South Africa. There is an urgent need to promote not only

Magnetic characteristics of the as-quenched fully and partially amorphous Al85Ni5Y4Fe2Co2 alloy were measured by VSM(vibrating sample magnetometer). The results show that the magnetization curves of the two alloys pass the origin of coordinates and extend through the first and the third quadrants, no remanence and coercivity were observed. The magnetism of the fully and partially amorphous alloys is all a combination of paramagnetism and diamagnetism. The magnetic susceptibility of the fully amorphous alloy is 2.41×10- 4and that of the partially amorphous alloy is 2.73×10- 4. The magnetisms of the alloys annealed at 330℃and 390℃ were also tested respectively. The magnetic susceptibility of the linear portion of the magnetization curve increases from 2.53×10-4to 2.81×10-4as the annealing temperature rises from 330℃ to 390℃. The hybrid microstructures of the alloys may account for the evolution of the corresponding magnetisms.

We propose to address a series of questions related to the evolution of languages by statistical analysis of written text. We develop a "statistical signature" of a language, analogous to the genetic signature proposed by Karlin in biology, and we show its stability within languages and its discriminative power between languages. Using this representation, we address the question of its trajectory during language evolution. We first reconstruct a phylogenetic tree of IE languages using this property, in this way showing that it also contains enough information to act as a "tracking" tag for a language during its evolution. One advantage of this kind of phylogenetic trees is that they do not depend on any semantic assessment or on any choice of words. We use the "statistical signature" to analyze a time-series of documents from four romance languages, following their transition from latin. The languages are italian, french, spanish and portuguese, and the time points correspond to all centuries from III bC to XX AD.


This study is a survey of dialect use, accent strength, knowledge and use of lexical dialect items, and attitude among adolescents in the Eindhoven area, an urbanized area in the Dutch province of North-Brabant. Regiolects tend to emerge and take over the functions of dialects in large parts of Europe, including the Netherlands, especially in urbanized areas. The basic research hypothesis of this study is that respondents report regiolect use more often than dialect use.

A group of data with the estimating of its uncertainties is exemplified by using the new method.


Realdo Colombo (Fig. 1), born in Cremona, Italy, between 1510 and 1515, published the first definitive description of the pulmonary circulation.1, 2 The son of an apothecary, he received his preliminary education in Milan. Colombo next began to study medicine as an apprentice to Giovanni Antonio Lonigo, a prominent Venetian surgeon. After 7 years in Venice with Lonigo, he moved to Padua to continue his medical studies at the university, a leading center for medical education. He arrived at Padua at an exciting time. Andreas Vesalius was writing and preparing the illustrations for his monumental anatomical work, De humani corporis fabrica libri septum. A superior student and talented anatomist, Colombo became Vesalius's assistant in 1541. He substituted for him during the 1542 term, when the senior anatomist was in Switzerland overseeing the printing of his book that would appear the following year. Their friendship ended soon, however, when Colombo criticized Vesalius publicly. After teaching anatomy in Pisa between 1545 and 1548, Colombo moved to Rome where he hoped to collaborate with Michelangelo on an illustrated anatomical textbook that would compete with Vesalius's atlas. He began teaching at the Sapienza and spent the rest of his life in Rome. During the middle of the sixteenth century, anatomical dissection grew in popularity in Paris and northern Italy, and Colombo flourished in this context. He lived at a time when a few anatomists were beginning to challenge Galen's anatomical teachings. Galen had dominated medical thought for almost 1400 years. But Colombo, like Vesalius, was not bound by tradition. They were interested in extending knowledge by direct observation. Colombo's knowledge of anatomy was gained firsthand—he performed countless autopsies, dissections, and vivisections during the 1540s and 1550s. Colombo's book, De re anatomica, incorporated his original observations and synthesized contemporary anatomical thought. Consisting of 15 chapters, the book was completed just before his death in 1559. Michelangelo had died 5 years earlier, so their planned collaboration did not come to fruition. The only illustration in Colombo's book is an elaborate engraving that depicts him performing a dissection. According to twentieth century scholars Robert Moes and C. D. O'Malley, the book was very popular and influential. Because "the language was uncomplicated and the descriptions succinct," they thought it was very likely that most contemporary anatomists and physicians "paid lip-service to the massive Fabrica [of Vesalius] and read De re anatomica."3 This rare book includes Colombo's original description of the pulmonary circulation, based on hundreds of dissections and vivisections he performed. This fact sets Colombo apart from two individuals who had already described the pulmonary circulation: the thirteenth century Arabic physician Ibn al-Nafis of Damascus and the Spanish biologist and philosopher Michael Servetus, who had described the pulmonary circulation in a theological book he published in 1553. Historian Leonard Wilson concluded that Colombo arrived at his conclusions about the pulmonary circulation independently.4 There was no printed version of Ibn al-Nafis's observations; they were passed on in Arabic manuscripts. Almost all copies of Servetus's book were destroyed the year it was published—when he was burned at the stake in Geneva for heresy. A comparison of their writings demonstrates that Colombo's understanding of the pulmonary circulation was more sophisticated than that of the other two writers. It was also based on extensive anatomical investigations. Galen completed his influential treatise on the usefulness of the parts of the body around 175 A.D. It included detailed discussions of the anatomy and physiology of the cardiovascular system. The ancient Greek physician believed that blood circulated from the right ventricle to the left ventricle through invisible pores in the interventricular septum.5 His notion of the Clin. Cardiol. 25, 135–137 (2002)

The author investigates the performance of transmitter space shift keying (TSSK) with maximum-ratio combining (MRC) and receiver spatial modulation (RSM) with maximum-ratio transmission (MRT) in an unbalanced number of antennas at the transmitter and receiver. The author shows that RSM-MRT exhibits a superior performance under the same data rate, transmit power, and bandwidth in downlink cellular network systems where the number of transmit antennas at the base station is much larger than the number of receiver antennas at the mobile station. The author identifies a figure of metric as fading parameters and finds their probability density function (PDF) and cumulative distribution function (CDF). The performance gap between TSSK-MRC and RSM-MRT expands as the number of antennas increases while maintaining the same ratio of the number of antennas at the transmitter and receiver for a chosen modulation.


Much of the current literature on streetscape design emphasizes a need for well-articulated edge conditions to enhance pedestrian-orientation and the reason appears to lie in evolutionary biology: humans have a psychological preference for wall-hugging due to a well-established trait in other species: thigmotaxis.,This study seeks to explore the relationship between urban facades and affective feelings through an empirical study, which asks: how do people perceive edge conditions in urban environments? Through a study of affect relative to edge conditions, greater insight can be generated as to the human experience in the built environment. We conducted a laboratory experiment with 76 subjects who each viewed 40 images of urban facades and rated each based on their emotional reaction.,Each subject also completed two validated individual trait difference measures. We found that those images depicting thigmotaxic facades were more highly rated than other facades.,High quality edge environment resulted in people feeling more pleasant than low quality edges.

The empirical results show that the proposed model outperforms than the conventional models.


A wireless sensor network WSN is a collection of autonomous sensors nodes organized into a cooperative network. A sensor node transmits the data quantity to the sink. Indeed, a failed sink may abort the overall mission of the network. Due to their crucial functions, sinks must be designed and maintained to be robust enough in order to face trouble coming from the harsh environment. Thus, as a keystone of a WSN, a sink has to be provided with ability to recover from failures. In this paper, we propose a new protocol avoiding to the sink to be a central point of failure. First, we model a sensor node failure estimation problem through a causal network. Then, we show how the checkpointing process ensures the recovery of the network. This approach reduces both energy consumption and communication bandwidth requirements, and prolongs the lifetime of WSN. Interesting results are given by simulation.


The study of the interaction of religion and state is determined by the fact that religion is one of the basic postulates of human life; it conducts the man since the beginning of civilization, penetrating into all spheres of his life and shaping his mind. Different stages of the Russian state are characterized by various forms of interaction of the state and religion: from the complete subordination of religious denominations to the state to their complete removal from public affairs. Religion, which was formed as a social institution of society, continuously generates the Institute of human existence, affecting social and political stability of the society, social and cultural situation. The role of religion and its importance for society and its impact on it, its relationship with the state as a social regulator, determines the relevance of the research. This article researches interaction of state and religion, the entity of this interaction, which is considered from the point of view of philosophical, sociological, historical and legal comprehension.


The current work was performed in 2018 aiming to study the geomorphological and pedological characteristics as well as classification and capability evaluation for soils of Menouf province area, Menoufia governorate, Egypt. The integration of Remote Sensing (RS) and Geographic Information System (GIS) techniques was used to achieve this work.
The geomorphic map produced by processing and identifying the Landsat image using RS and GIS technology indicated that, the main landscape unit in the studied area is Alluvial Plain includes nine landforms namely: high terraces (19.4% of the studied area), medium terraces (15.3%), low terraces (24.6%), over flow basin (25.6 %), decantation basin (7.9%) in addition to meandering belt, depression, levee, and island (with small areas).
Twenty-four soil profiles were chosen to represent the different landforms.The land and site features are observed and registered. The soil profiles were dug, morphologically described, and then samples were collected representing the subsequent layers in each profile for integrated physical and chemical analyses.
The studied area has almost flat topography with deep soil profiles and freely well drained. These soils have loam to sandy clay loam texture with moderate medium sub angular to angular blocky structure.
The analytical data revealed that, the studied soils are moderately alkaline, non-saline and haven't sodicity effect. The soils are slightly calcareous having very slight gypsum content. Organic matter (OM) is lowand decreases with depth. The cation exchange capacity (CEC) is correlated to the fine fractions and OM contents in these soils.
The studied soil profiles haven't any diagnostic horizons, therefore they were classified up to sub great group level under Entisols order mainly as Typic Torriorthents.
The land capability evaluation indicated that, about 48% of the studied soils have a Good capability class (C2) and the rest (52%) are considered as a Fair (C3) one.


In this paper we present a method which assigns to each layer of a multilayer neural network, whose network dynamics is governed by a noisy winner-take-all mechanism, a neural temperature. This neural temperature is obtained by a least mean square fit of the probability distribution of the noisy winner-take-all mechanism to the distribution of a softmax mechanism, which has a well defined temperature as free parameter. We call this approximated temperature resulting from the optimization step the neural temperature. We apply this method to a multilayer neural network during learning the XOR-problem with a Hebb-like learning rule and show that after a transient the neural temperature decreases in each layer according to a power law. This indicates a self-organized annealing behavior induced by the learning rule itself instead of an external adjustment of a control parameter as in physically motivated optimization methods e.g. simulated annealing.


Abstract Let (𝔤,𝗀){\mathfrak{g},\mathsf{g})} be a pair of complex finite-dimensional simple Lie algebras whose Dynkin diagrams are related by (un)folding, with 𝗀{\mathsf{g}} being of simply-laced type. We construct a collection of ring isomorphisms between the quantum Grothendieck rings of monoidal categories 𝒞𝔤{\mathscr{C}_{\mathfrak{g}}} and 𝒞𝗀{\mathscr{C}_{\mathsf{g}}} of finite-dimensional representations over the quantum loop algebras of 𝔤{\mathfrak{g}} and 𝗀{\mathsf{g}}, respectively. As a consequence, we solve long-standing problems: the positivity of the analogs of Kazhdan–Lusztig polynomials and the positivity of the structure constants of the quantum Grothendieck rings for any non-simply-laced 𝔤{\mathfrak{g}}. In addition, comparing our isomorphisms with the categorical relations arising from the generalized quantum affine Schur–Weyl dualities, we prove the analog of Kazhdan–Lusztig conjecture (formulated in [D. Hernandez, Algebraic approach to q,tq,t-characters, Adv. Math. 187 2004, 1, 1–52]) for simple modules in remarkable monoidal subcategories of 𝒞𝔤{\mathscr{C}_{\mathfrak{g}}} for any non-simply-laced 𝔤{\mathfrak{g}}, and for any simple finite-dimensional modules in 𝒞𝔤{\mathscr{C}_{\mathfrak{g}}} for 𝔤{\mathfrak{g}} of type Bn{\mathrm{B}_{n}}. In the course of the proof we obtain and combine several new ingredients. In particular, we establish a quantum analog of T-systems, and also we generalize the isomorphisms of [D. Hernandez and B. Leclerc, Quantum Grothendieck rings and derived Hall algebras, J. reine angew. Math. 701 2015, 77–126, D. Hernandez and H. Oya, Quantum Grothendieck ring isomorphisms, cluster algebras and Kazhdan–Lusztig algorithm, Adv. Math. 347 2019, 192–272] to all 𝔤{\mathfrak{g}} in a unified way, that is, isomorphisms between subalgebras of the quantum group of 𝗀{\mathsf{g}} and subalgebras of the quantum Grothendieck ring of 𝒞𝔤{\mathscr{C}_{\mathfrak{g}}}.


Until recently mental diseases were treated as a whole, without any differentiation. Recent researchs have highlighted the differences between some of them, so consequently there are specific treatments for these pathologies today. The main objective of this work is to show two different diseases which in many cases are confused: depression and schizophrenia. These pathologies can have as triggers situations very diverse and that require different treatment. For the analysis, we are going to use two films: Prozac Nation (2001) by Erik Skjoldbjaerg and A beautiful mind (2001) by Ron Howard, which reflect the real experiences of two characters; the society in which they live and the environment around them, but especially focusing in the pharmacotherapy area, medications used, its correct use, the adverse effects and so on; in order to be able to decide if the vision presented by films has a formative character in these diseases.

Distinctive individuals can share that information through diverse virtual machines yet show on single physical machine.


This study was conducted to investigate the optimal culture condition of lily bulblets in a bioreactor. Asiatic hybrid 'Mirr' was used to analyze the effects of growth regulator, sucrose concentration, and charcoal on the endogenous contents of ABA, t-zeatin, starch, and starch accumulation in bulblets. Treatment with growth regulator, BA 0.1 mg L -1 and IAA 0.1 mg L -1 , resulted in the highest bulblet proliferation in liquid culture with 5.8 bulblets per scale. Addition of 6% sucrose with 0.1% charcoal to the MS medium showed three times higher bulblet enlargement with 8.4 g per bulblet, compared to 3% sucrose alone at 2.7 g/bulblet. Starch content was higher with 9% sucrose with 0.1% charcoal, and accumulation of starch in the cell showed subsequent increases with sucrose concentration in the medium. The starch accumulation was higher in solid agar medium than in the liquid medium. ABA content was lower at 3% sucrose, than other concentrations. This was probably due to a relationship between the bulblet enlargement and endogenous ABA content. The t-zeatin content was highest in the 6% sucrose and 0.1% charcoal treatment. A liquid culture method using an Ebb & flow system resulted in better bulblet enlargement, especially in 6% sucrose treatments, than the ordinary liquid culture method.


this paper presents a hybrid technique for image enhancement with ability of de-noising it integrates two different processing aspects into one. The proposed algorithm uses the image abstraction technique for detecting the information density in different parts of image then accordingly operates the smoothing filter and after filtering the information's of edges are recombined with the filtered image. The proposed technique also utilizes the Neural Network for filtering noise generated edge patterns. Hence the approach not only enhances the image but also avoids the enhancement of noise. The simulation of algorithm shows that it improves the perception; remove noise while maintaining the structure information intact it is also found that the proposed technique is quite fast.

The title compound, C16H11N3O3, (I), exists in crystals as the pure hydrazone tautomer. Molecules form stacks stretched along [100]. AM1 calculations of the crystal electrostatic potential show that the crystal environment causes only a 24% increase in the molecular dipole moment of (I).


Microscopic examination of urinary sediment (U -sed) is an affordable and reliable diagnostic tool that constitutes a cornerstone of renal care. It provides essential information for the understanding of the pathophysiology of kidney injury. In recent decades it has become increasingly rare for this exam be performed by nephrologists, mainly due to the widespread diffusion of automated technologies and centralization of laboratory testing. The growing reliance on automated technology set the current path of continuous loss of nephrologists' skills and training opportunities for U -sed microscopy.


A growing issue on a global scale is the emergence of helminth species and populations that are resistant to one or more anthelmintics. The majority of currently available anthelmintics used to control parasitic nematodes of cattle and sheep belong to only three main groups, benzimidazoles, imidazothiazoles and avermectins/milbemycins. The availability of reliable and precise techniques for its identification and monitoring is a critical component of the success of helminth control programs intended to prevent the spread of resistance in nematode populations. In vivo method like fecal egg count reduction test and in vitro methods such as egg hatch assays, larval motility test, larval development test and polymerase chain reaction (PCR) can be used for the detection of anthelmintic resistance although each has some reliability, repeatability, sensitivity, and ease of interpretation issues. The genetic basis of resistance to the majority of anthelmintics are still not well understood. Thanks to recent developments in high-throughput sequencing, it is now possible to define features such as drug resistance using genome-wide techniques. Keywords: Anthelmintics; Helminths; Resistance; Detection assays; Molecular diagnostics; Parasite control


ABSTRACT The COVID-19 pandemic brought booming economies, seemingly world-class health care systems, educational infrastructures, and the lives and well-being of nations to a complete standstill. Georgia was one of the few states that released their Shelter-in-Place order early, while reports suggest that Black communities have disproportionally higher rates of deaths and hospitalizations. What mathematics would allow students to critically examine the data shared and other data reported about the COVID-19 pandemic? In this essay, we apply a culturally relevant pedagogical (CRP) lens to examine the mathematics curriculum taught in K-12 schools before and during the COVID-19 pandemic. Specifically, we consider the shortcomings of the curriculum given the impact of the pandemic on Black communities in Atlanta, Georgia, and the barrage of statistics used to inform their lives. We consider how to look at mathematics curriculum through a CRP lens and what that means in terms of the scope of standards that are being addressed and the flexibility for teachers to have autonomy to go beyond the prescribed curriculum. Two concentration areas are addressed, and they highlight how to use a CRP lens for secondary and elementary mathematics relevant to our local context in ways that envision how mathematics curriculum can support Black children moving forward.


Through sequencing of clones randomly selected from previously constructed high quality c DNA library of Olimarabidopsis pumila,we got an expressed sequence tags(EST) which was highly similar to NAC transcription factor gene NAC083 of Arabidopsis thalania.It contained a complete open reading frame(ORF)with 723 bp,designated Op NAC083,encoding 240 amino acids.The primers were designed according to the sequence of ORF and Op NAC083 was identified from O.pumila by RT-PCR and clone techniques.Bioinformatics analysis showed that Op NAC083 contains 33 α-helixes and11 β-turns,and a No apical meristem(NAM) at its N-terminal region.Phylogenetic tree analysis revealed that Op NAC083 showed closer genetic kinship with A.thaliana At NAC083 and A.lyrata ANAC083,indicating that they belonged to the same evolutionary branch.Quantitative Real-Time PCR(q RT-PCR) revealed that Op NAC083 displayed a much broader expression range in O.pumila different tissues,with a maximum expression in leaves.The level of Op NAC083 transcription was upregulated after 2 h of Na Cl and 6 h of ABA treatment.However,its transcription was inhibited by PEG-6000 and 4 ℃treatment.Our research indicated that Op NAC083 played an important role in response to salt and ABA stress in O.pumila.


We determine conditions under which a random biochemical system is likely to contain a subsystem that is both autocatalytic and able to survive on some ambient `food' source. Such systems have previously been investigated for their relevance to origin-of-life models. In this paper we extend earlier work, by finding precisely the order of catalysation required for the emergence of such self-sustaining autocatalytic networks. This answers questions raised in earlier papers, yet also allows for a more general class of models. We also show that a recently-described polynomial time algorithm for determining whether a catalytic reaction system contains an autocatalytic, self-sustaining subsystem is unlikely to adapt to allow inhibitory catalysation - in this case we show that the associated decision problem is NP-complete.


Cells in the composition of the culture medium, such as, ethanolamine, growth factors, and to increase the stability of the unstable components such as vitamins, or a method of protection are provided. Stability of unstable compounds is increased by derivatization by (derivatization), or isolation of unstable compounds Chemistry (sequestering) to the chemical instability of the compound. Isolated screen may be performed by the use of, or isolated by a screen formulation encapsulated in the microcapsules. Encapsulated comprises an encapsulated complex of dendritic polymer of sensitive compounds in the microcapsules and to provide a controlled release of sensitivity (susceptible) compound that was protected by it. These methods can improve the transfer and handling of the composition comprising a stable compound, such as a drying medium formulation waters in and improve the storage conditions of the composition, and extend, rather than the low-temperature room temperature, including unstable compound, which the causes transport costs It decreases. Stabilization of unstable compounds in the same composition and drying type medium can be viewed as a contribution to the green and Technology.


This paper presents a 3D safe path planning solution for UAS in cluttered environments. 3D any-angle path planning algorithms are used by including non-uniform costs related to distance to the closest obstacles. Both Theta* and Lazy Theta* algorithms are extended toward non-uniform costs by fostering safety and smoothness. Our generalized algorithms consider the cost of all the nodes along the line of sight between an initial and final node. Tests in a realistic environment are performed to evaluate the generalized Theta* and Lazy Theta* algorithms with respect to A* algorithm considering the nonuniform costs. The results show advantages of the generalized Lazy Theta* algorithm related to safety, length and smoothness of path.


Our clinical study 1 of exophthalmic goiter suggested an investigation of the involuntary nervous system. The manifestations of exophthalmic goiter may be divided into the metabolic disturbance measured by the basal metabolism, and the sympathomimetic symptoms (tachycardia, exophthalmos, polyrrhea, sweating, etc.). The latter have been so called because they may be produced by stimulation of the thoracicolumber division of the involuntary nervous system. Not all persons with sympathomimetic symptoms have elevation of the basal metabolism. To a clinical association of sympathomimetic symptoms and normal basal metabolism, we have applied the term "autonomic imbalance." 2 Our clinical studies of autonomic imbalance failed to reveal the predisposing causes. The exciting causes may be divided into physiologic and pathologic. The most prominent physiologic factor is the sex epochs, particularly in the female, and the most frequent pathologic factor is foci of infection in the nasopharynx. Our patients showed considerable range in their symptoms:


Rubber trees (Hevea brasiliensis) are the main source of natural rubber, extracted from latex, which exudes from the trunk after tapping. Tapped trees require large amounts of carbon (C) to regenerate the latex after its collection. Knowing the contribution of C sources involved in latex biosynthesis will help understand how rubber trees face this additional C demand. Whole crown 13CO2 pulse labelling was performed on 4-year-old rubber trees in June when latex production was low and in October, when it was high. 13C contents were quantified in the foliage, phloem sap, wood and latex. In both labelling periods, 13C was recovered in latex just after labelling, indicating that part of the carbohydrates was directly allocated to latex. However, significant 13C amounts were still recovered in latex after 100 days and the peak was reached significantly later than in phloem sap, demonstrating the contribution of a reserve pool as a source of latex C. The contribution of new photosynthates to latex regeneration was faster and higher when latex metabolism was well established, in October than in June. An improved understanding of C dynamics and source-sink relationship in rubber tree is crucial to adapt tapping system practices and ensure sustainable latex production.


Walter F. Lever compiles in one source the many contributions he has made to the understanding of these blistering diseases. He discusses not only his own wide personal experience with these diseases but includes an extensive review of the literature. The clinical data, histologic alterations including electron microscopic changes, laboratory findings, differential diagnosis, and treatment of the various forms of pemphigus and pemphigoid are discussed in detail. The text is clearly written and is easily understood. The author's classification of these bullous eruptions into specific categories on the basis of clinical and histologic changes seems to be sufficiently specific to permit the reader to define each of the entities without ambiguity. Not all dermatologists would agree that these diseases can be so precisely classified. I agree with Lever's concepts; however, I have encountered a few cases of these kinds of bullous eruptions that defy specific categorization by the clinical or


In this study, de nition of involute-evolute curves for semi-dual quaternionic curves in semi-dual spaces D42 known as dual split quaternion and D31 are given and also some well-known theorems for involute-evolute dual split quaternionic curves are obtained.


Laboratory studies of absorption-frequency behavior in rocks often use spectral ratios of digitally recorded ultrasonic signals which have been transmitted through a rock sample and a reference sample of very low absorption, respectively. It is proposed to treat the digitally recorded signals as an autoregressive-moving average (ARMA) process which, using recursive filter concepts, can be represented as a ratio of two polynomials in the z-transform variable z. The numerator polynomial contains only that part of the signal that is modified by anelastic effects, whereas the denominator contains the elastic effects of the physical apparatus such as reverberations. Examples are given which show that this separation of the recorded signal greatly facilitates the laboratory investigation of loss mechanisms and absorption-frequency behavior based on spectral ratios.


Purpose of reviewTo provide an updated list of genetic and environmental causative factors of autoimmune thyroid disease, and report about the recent discoveries concerning their interaction in the pathogenesis of thyroid autoimmunity. Recent findingsAlthough significant discoveries have been made on genetic and environmental factors underlying the development of autoimmune thyroid disease, few data are available about the mechanisms by which they interact. The most interesting news in this field comes from research on molecular mimicry between microbial antigens and thyroid autoantigens. The molecular mimicry model postulates that, in predisposed subjects, a microbial antigen could trigger autoimmunity because of its structural similarity to an autoantigen of the host, and is a paradigmatic example of the multifactorial interaction of several genes and environmental factors to cause autoimmune diseases, including thyroid diseases. SummaryRecent findings help us to better understand the functional mechanisms of the immune system, which are still only partially known. Beyond the scientific interest, this knowledge has immediate repercussions on clinical practice because it can suggest possible therapeutic targets for new treatments, as well as better and more specific uses of currently available drugs and resources.

This study aims at developing ergonomics patterns for the sleeve of structural firefighting protective clothing through 3D motion analysis in order to ensure efficiency and safety of firefighters who are exposed to harmful envi- ronment at work. A new research pattern was developed by applying the total results of 3D motion analysis, changes of body surface length measurements, and 2D data on 3D body shape analysis on the size 3 patterns of the existing coat sleeve. For the sleeves, we used the body surface length of the range of shoulder's flexion and the joint angle of the range of wrist's ulnar deviation. And for the production of structural firefighting protective clothing using the research pattern, we recruited a recognized producer of structural firefighting protective clothing designated by KFI. Unlike everyday clothes, structural firefighting protective clothing should be able to fully protect the wearers from the harmful envi- ronment that threatens their lives and should not cause any restrictions on their movement. Therefore, the focus of research and development of such protective clothing should be placed on consistent development of new technologies and production methods that will provide protection and comfort for the wearer rather than production cost reduction or operational efficiency. This study is meaningful as it applied 3D motion analysis instead of the existing methods to develop the patterns. In particular, since 3D motion analysis enables the measurement of the range of motion, there should be continuous research on the development of ergonomics patterns that consider workers' range of motion.


In a single piece, the Irk Bitig is the only text that has written in the form of a book in Old Turkic runic alphabet and survives. This book, which was found in the Halls of the Thousand Buddhas near Tun-huang, consists of various irks (omens). This omen book contains short interpretations of 65 irks and a colophon. It was written Manichaean "ny" dialect. Namely, the book has Old Uighur dialect characteristics. It is not known when the Irk Bitig exactly has written. The aim of this article is to examine adverbs and adverbial constructions in the Irk Bitig. Therefore, the article consists of three main parts. In the first part, I will dwell on the function of adverbs and adverbials. In the second and third part, I will investigate their structure and meaning.


A French construction company, Cipec, was recently given the task of replacing more than 400 supports beneath a highway that encircles Paris. The work on the Peripherique (ring road) had to be done without any interruption of traffic at the Parc des Expositions, the city's leading exhibition center near the Porte de Versailles. This article describes the specialized equipment and methods that were used to complete this project.


The fast multipole method (FMM) has become an important alternative to traditional methods such as the Ewald method for computing the long‐range interactions necessary to simulate charged or dipolar systems. In this paper, we present an improvement of this method, which we shall call the very fast multipole method (VFMM). The VFMM is shown to be a factor of about 1.2 faster than the FMM for two‐dimensional systems and a factor about 2–3 times faster for three‐dimensional systems without losing any accuracy for the worst case error.

Amphiphilic random copolymers based on vinyl ether of ethylene glycol and vinyl butyl ether as well as their polycomplexes with poly(acrylic acid) were studied as polymeric reagents for the stabilization of water/n-hexane emulsions. The emulsion stability strongly depended on the content of vinyl butyl ether in the copolymers as well as their concentration in solution. The more hydrophobic copolymers stabilized emulsions more efficiently. An increase in the temperature and the addition of inorganic salts reduced the emulsion lifetime. The formation of interpolymer complexes between the copolymers and poly(acrylic acid) significantly influenced the stability of the emulsions.

Guiding by the view of science-based development, the ecological tax system which also possesses the benefits of encouragement and financing capital should be gradually established, so the material benefits can stimulate and drive that the social pollution costs are translated into production costs and market price, and the policy and law objectives to control ecological pollution and improve ecological quality can be realized. According to the requirements of sustainable development, China present tax system should be adjusted, and the relatively perfect ecological tax system should be gradually established. In this article, we put forward main countermeasures including the taxation to ecological pollution tax, the reform to resource tax system, and the adjustments to corresponding articles of other tax types about environmental protection.


In this note I obtain bounds for the least integral solutions of the equation in terms of For ternary diagonal forms, such bounds have been given by Axel Thue (4) and, more recently, by Holzer (1), Mordell (2) and Skolem (3), but these lead only to bad estimates for general ternaries. So far as I know there have not been given estimates for n≽4. Here I generalize Thue's method to prove: Theorem. Suppose that n ≥ 2 and that f(ɛ) represents zero. Then there is an integral solution of f(a) = 0 with

at the head of the class. It is also unfortunate that the " orders" of birds are perpetuated, even in a popular work, since it is doubtful whether they should rank higher than sub-orders. The singing birds (Passeres) are treated with great fullness of detail, and as these form the larger proportion of our native birds, amateurs and naturalists will find this a most popular and useful part of the work. The index of each volume is voluminous, while the illustrations are abundant and beautiful, the two volunmes containing 346 woodcuts, many of them of life size, and thirty-seven full-page engravings, mostly drawn by Miitzel, Kretschnmer and others. They are fully up to the standard of those in the earlier volumes of the series, to which we have called attention. The birds will be completed in a third volume. Two additional volumes will be devoted to fishes, finishing the series of ten volumes announced by the publisher, and which will, without doubt, be issued during the coming year.


The patterns of our town and city centres will continue to change as the needs and orientations of our society change. Today the city centres face real challenges. They must respond to the changing needs and demands of modern-day living if they are to survive. They must provide places, which are attractive, welcoming and safe. City centres come to terms with changing circumstances at the end of the twentieth century. One of these circumstances is terrorism.

Solitary peripheral osteoma of the mandible is singularly accounted and only a few cases not related to the Gardner's syndrome is offered in the literature. Osteoma is a benign osteogenic neoplasm. The most familiar site of occurrence in the mandible is the posterior part and it is customarily asymptomatic. Osteoma is usually ascertained accidentally in case of mandible where it poses as an esthetic predicament. Peripheral osteoma has a distinctive clinical and radiographic appearance, but its exact pathogenesis is incomprehensible. Enumerated here is a patient with a peripheral osteoma of the mandible at an atypical site; which might have occurred as a result of a combination of trauma and muscle traction.


Four test parameters of beef quality are meat color, fat color, marbling, and tenderness. Beef tenderness measurement's parameters are not workable for visual assessment, because it has no visual standard. One of the tenderness assessment methods requires international standard tools such as Warner-Bratzler. This manual technique has a disadvantage that is not real time and the measurement method causes the beef is not worth consuming because it must be cooked and cut into pieces. The vision parameters that are closely related to tenderness are beef texture. A method has been developed to extract the beef texture as the basic features in the beef classification process. Texture feature's extraction uses statistical analysis of Gray Level Co-occurrence Matrix (GLCM) and domain frequencies Discrete Wavelet Transform (DWT). The correlation test shows that contrast, correlation, energy, and homogeneity features of the GLCM and the diagonal and vertical details of the DWT have significant correlations. The accuracy, precision, and recall for the classification performance reach a hundred percent using Support Vector Machine method with polynomial kernel.

The region from eastern Bhutan to Arunachal Pradesh of India and the adjacent south-eastern Tibet and northern Myanmar seems to be one of the last frontiers not only for Meconopsis hunting but also for other botanical exploration. Although there remain political difficulties for foreigners to approach the unsettled border between India and China, including the famous Tsari valley with its prominently rich flora, which was visited by Frank Ludlow, George Sherriff, Frank Kingdon-Ward and a few other plant hunters before 1950, some botanical and horticultural treasures in this region have gradually been revealed to recent travellers. As a result of examining the photographs taken by these travellers and our own botanical field research in eastern Bhutan in 2014, accompaniedby subsequent herbarium studies, two species new to science are described. The first, from eastern Bhutan and adjacent Arunachal Pradesh and Tibet, has long been cultivated under the names M. grandis or M. grandis GS600, and has recently been described as M. grandis subsp. orientalis (Grey-Wilson, 2010). It is the national flower of Bhutan. However, the type of M. grandis from Sikkim belongs to a species quite distinct from the eastern populations and the latter is now described as a new species, Meconopsis gakyidiana. The second novelty, Meconopsis merakensis,is newly described from eastern Bhutan and adjacent Arunachal Pradesh. In the past this species was confused with the closely allied M. prainiana. The two species are isolated geographically, M.prainiana being found only much further to the north-east, in south-eastern Tibet, including theTsari valley. The title of this article is based on a comparison made by Frank Kingdon-Ward of Meconopsis flowers with butterflies in Tibet (see below).

AbstractAs a natural phenomenon, drought can have devastating impacts on local populations through food insecurity and famine in the developing world, such as in Africa. In this study, the authors have established a seasonal hydrologic forecasting system for Africa. The system is based on the Climate Forecast System, version 2 (CFSv2), and the Variable Infiltration Capacity (VIC) land surface model. With a set of 26-yr (1982–2007) seasonal hydrologic hindcasts run at 0.25°, the probabilistic drought forecasts are validated using the 6-month Standard Precipitation Index (SPI6) and soil moisture percentile as indices. In terms of Brier skill score (BSS), the system is more skillful than climatology out to 3–5 months, except for the forecast of soil moisture drought over central Africa. The spatial distribution of BSS, which is similar to the pattern of persistency, shows more heterogeneity for soil moisture than the SPI6. Drought forecasts based on SPI6 are generally more skillful than for soil moisture, an...

We report an experimental study of correlated multiple light scattering in an ultracold gas of ${}^{85}\mathrm{Rb}$ confined in a magneto-optic trap. Measurements are made of the polarization dependence of the spatial and spectral profile of light backscattered from the sample. The results show an interferometric enhancement sensitive to coherent multiple scattering in the atomic gas, and strong variations with the polarization of the incident and detected light. The spatial width and peak value of the enhancement are found to be dependent on the sample size. Comparison of all the measurements with realistic quantum Monte Carlo simulations yields a very good agreement.
