    From statistical mechanics, this thesis looks for a phase transition signal in nuclei. We try to describe critical aspects of the nuclear multifragmentation. Thermodynamical observables as fragment mass/charge distributions are used in those finite systems. The percolation theory is first applied to strictly statistical events from the lattice gas model framework at the thermodynamical critical point. The scaling functions obtained are quantitatively comparable for every sample. Critical exponents are almost the same as the liquid/gas universality class ones. The second part is devoted to Fisher's model framework taking into account for the chemical potential and the surface energy coefficient. The extracted critical temperature is compatible with the percolation one. Experimental samples are then studied from peripheral (Au+Au) and central (Xe+Sn) heavy ion collisions. Entrance channel memory effects are evidenced in peripheral events. The presence of collective flow make the central ones far away from the conditions required by Fisher's model. Nevertheless, the critical energy found is independent of the data characteristics. This curious stability has to be studied. (authors)

    Inelastic scattering of medium energy a particles by nuclei is known to excite preferentially levels of collective character. We have studied the scattering of isotopically enriched targets of Ca, Fe, Ni, Cu, Zn. In part I, we discuss the theoretical features of the interaction. In part II, we describe the experimental procedure. Results are presented and analysed in part III. {alpha} particles scattering by Ca{sup 40} is showed to excite preferentially odd parity levels. In odd nuclei we have observed multiplets due to the coupling of the odd nucleon with the even-even core vibrations. For even-even nuclei, a few levels are excited with lower cross-sections between the well-known first 2{sup +} and 3{sup -} states. Some could be members of the two phonon quadrupole excitation and involve a double nuclear excitation process. (author) [French] On sait que la diffusion inelastique des particules alpha de moyenne energie excite preferentiellement des niveaux de caractere collectif. Nous avons etudie la diffusion des particules alpha de 44 MeV du cyclotron de Saclay par des isotopes separes de Ca, Fe, Ni, Cu, Zn. Dans la premiere partie nous exposons les theories de cette interaction. Dans la seconde nous decrivons le systeme experimental. Les resultats sont donnes dans la troisieme partie. Nous montrons que les niveaux excites preferentiellement pour {sup 40}Ca par diffusion ({alpha},{alpha}') sont de parite negative. Dans les noyaux pair-impair nous avons observe des multiplets dus au couplage du nucleon celibataire avec les vibrations du coeur pair-pair. Pour les noyaux pair-pair nous avons pu etudier entre le premier niveau 2{sup +} et le niveau 3{sup -} deja bien connus certains etats plus faiblement excites. Il semble qu'ils sont dus a une excitation quadrupolaire a deux phonons et impliquent un processus de double excitation nucleaire. (auteur)

    The nuclear fuel is one of the key component of a nuclear reactor. Inside it, the fission reactions of heavy atoms, uranium and plutonium, take place. It is located in the core of the reactor, but also in the core of the whole nuclear system. Its design and properties influence the behaviour, the efficiency and the safety of the reactor. Even if it represents a weak share of the generated electricity cost, its proper use represents an important economic stake. Important improvements remain to be made to increase its residence time inside the reactor, to supply more energy, and to improve its robustness. Beyond the economical and safety considerations, strategical questions have to find an answer, like the use of plutonium, the management of resources and the management of nuclear wastes and real technological challenges have to be taken up. This monograph summarizes the existing knowledge about the nuclear fuel, its behaviour inside the reactor, its limits of use, and its R and D tracks. It illustrates also the researches in progress and presents some key results obtained recently. Content: 1 - Introduction; 2 - The fuel of water-cooled reactors: aspect, fabrication, behaviour of UO{sub 2} and MOX fuels inside the reactor, behaviour in loss of tightness situation, microscopic morphology of fuel ceramics and evolution under irradiation - migration and localisation of fission products in UOX and MOX matrices, modeling of fuels behaviour - modeling of defects and fission products in the UO{sub 2} ceramics by ab initio calculations, cladding and assembly materials, pellet-cladding interaction, advanced UO{sub 2} and MOX ceramics, mechanical behaviour of the fuel assembly, fuel during a loss of coolant accident, fuel during a reactivity accident, fuel during a serious accident, fuel management inside reactor cores, fuel cycle materials balance, long-term behaviour of the spent fuel, fuel of boiling water reactors; 3 - the fuel of liquid metal fast reactors: fast

(author) [French] On propose un bilan des travaux les plus significatifs effectues en France depuis la deuxieme conference internationale en matiere d'agronomie nucleaire et qui vont d'une recherche apparemment desinteressee a l'application la plus directe. Une telle differenciation recouvre de moins en moins, au fur et a mesure de l'evolution des programmes, la distinction qui est faite dans l'expose entre l'action biologique des rayonnements et les autres emplois des techniques nucleaires. C'est ainsi que les recherches do radiogenetique agricole sont poursuivies dans deux directions: d'un point de vue theorique et methodologique avec l'etude comparative de l'action des divers types de rayonnements, l'influence du debit de dose et de la temperature, l'action des agents mutagenes chimiques, la production de chimeres sous irradiation gamma; et d'autre part, sous un aspect pratique aboutissant a la creation de varietes nouvelles plus resistantes ou plus precoces (riz, mil, arachide).

    This article is a short version of the ENET number 210359. This report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made to assess the economic consequences of two models for the opting out of nuclear energy in Switzerland, as proposed in two popular initiatives. The 'Sortir du nucleaire' (electricity without atomic power) initiative calls for the shutting down of the existing nuclear power stations and the 'Moratoire-plus' initiative calls for a stop on the building of new atomic power stations for 10 years. The method used for assessing the costs and benefits resulting if the initiatives were accepted in a public vote is described. Basic assumptions made on further factors concerning the electricity and energy markets are discussed. Results of analyses made for various scenarios with respect to CO 2 emissions are presented and include discussions on risk costs, effects on employment and welfare aspects

    French regulations on nuclear pressure equipment have been updated with the December 12, 2005 Order related to Nuclear Pressure Equipment, so-called 'ESPN Order'. This Order is at the junction of regulations covering safety on the one hand and pressure equipment on the other hand. As regards manufacturing, the ESPN Order extends to nuclear pressure equipment the approach and essential requirements of the European Pressure Equipment Directive (PED - transposed in France by the December 13, 1999 Decree) while adding specific nuclear and radiation safety requirements. For in-service inspection, it sets additional provisions to those of the December 13, 1999 Decree so that the nuclear and radiation safety requirements applying in nuclear facilities are also taken into account for those equipment. The specific case of PWR main primary and secondary systems is covered by the November 10, 1999 Order. The ESPN Order leaves a major part to industrial codes and standards. Its publication makes it necessary to check that the codes used for nuclear pressure equipment comply with the new requirements and may induce modifications of the codes. Furthermore, as the market for operators of nuclear facilities and manufacturers of mechanical equipment is becoming global, these evolutions should be considered in a worldwide context. Last, the Nuclear Transparency and Security Act of June 13, 2006 - which created the Nuclear safety authority (ASN) with competence over nuclear and radiation safety, covering specifically nuclear pressure equipment - will induce further amendments of regulations.

    This colloquium took place less than 1 year after the decision of the US of revival of their nuclear program. Thus the international context has changed, even if nuclear contestation remains as strong as in the past. Among governments, some positions preach the banishment of nuclear energy while others consider the nuclear option as the only solution to meet the growing up energy demand and the future environmental and economical stakes. This report makes a synthesis of the different talks given by the participants during the 3 round tables of the colloquium on the future of nuclear energy: the ecological stake, the democratic stake, and the energy policy stake. Four talks of French government representatives open and conclude the debates of the different round tables. (J.S.)

Along with examples of people who left their homes with taking with them a single object, the authors describe and comment how this evacuation occurred, the problems faced by the authorities for refugee reception and accommodation. This evacuation has been either organised or spontaneous. Hospitals had to be evacuated as well. Then, local authorities faced food shortage. Some animals have been saved, other starved to death. Dead animals are covered with lime. Dead bodies are decontaminated before being given back to families. Tests are regularly performed to assess people contamination. A second article discussed the bad news concerning the different Fukushima reactors with their melted cores. The geophysical aspects of the earthquake are evoked in a last article

    The considerable needs in research workers and scientists which are asked by the nuclear energy obliged the Commissariat a l'Energie atomique to deal with a particular effort to increase the quantitative and qualitative formation of scientists. Most various ways have been used. 1- A National Institute of Nuclear Sciences and Nuclear Techniques was created, by a joint decree of the Prime Minister and the Minister for National Education (june 18, 1957). This Institute of Higher Teaching (250 students) indulges in the following matters: atomic engineering, quantum mechanics, theory and technic of particle accelerators, special metallurgy, radiobiology, thermic and mechanics of fluids. 2- An associated centre of the 'Conservatoire National des Arts et Metiers' was created (200 students) for technical assistants, drawers, etc. 3- In contribution with both electronic industry and Ministry of Work, the Centre d'Etudes Nucleaires contributes to an accelerated formation of technical assistants into Professional Centres. Conclusion: Training of scientists and research workers is one of the most important activities of the Centre d'Etudes Nucleaires de Saclay. Without losing its technical efficiency, it has supplied and varied means adapted to the various purposes that we shall reach. (author) [fr

    This issue gathers the abstracts of the papers presented at the ninth European nuclear conference (ENC-2005). The main part of the conference is split into 20 sessions. These sessions cover all technical aspects of nuclear power, from reactor design to waste management, without forgetting experimental and research reactors, reactor dismantling, economy, resources, safety, radioprotection and education issues. Perspectives of a nuclear renaissance are clearly visible in the world. This renaissance, mainly due to political, economical, societal and ecological factors, is fuelled by scientific and technical progress. This conference was the opportunity to present together these aspects of nuclear power and to analyze their mutual interactions.

    for nuclear installations, the dismantling is an important part of their exploitation. The technology of dismantling is existing and to get a benefit from the radioactive decay, it seems more easy for operating company such E.D.F. to wait for fifty years before dismantling. But in order to get the knowledge of this operation, the Safety Authority wanted to devote this issue of `Controle`to the dismantling method. This issue includes: the legal aspects, the risks assessment, the dismantling policy at E.D.F., the site of Brennilis (first French experience of dismantling), the dismantling techniques, the first dismantling of a fuel reprocessing plant, comparison with classical installations, economic aspect, some German experiences, the cleansing of the american site of Handford.

    Can-rupture detection (DRG) is one important aspect of pile safety, more particularly so in the case of gas-cooled reactors. A rapid and sure detection constitutes also an improvement as far as the efficiency of electricity-producing nuclear power stations are concerned. Among the numerous can-rupture detection methods, that based on the measurement of the concentration of short-lived fission gases in the heat-carrying fluid has proved to be the most sensitive and the most rapid. A systematic study of detectors based on the electrostatic collection of the daughter products of fission gases has been undertaken with a view to equip the reactors EL 2, G 3, EDF 1, EDF 2 and EDF 3, the gas loops of PEGASE and EL 4. The different parameters are studied in detail in order to obtain a maximum sensitivity and to make it possible to construct detection devices having the maximum operational reliability and requiring the minimum maintenance. The primary applications of these devices are examined in the case of the above-mentioned reactors. (author) [French] La Detection des Ruptures de Gaines (D. R.

    The United Nations organisation and nuclear energy rose simultaneously, in 1945, to occupy an important place in the public eye. The spiritual succession of the League of Nations which had foundered during the war was taken up by the new organisation which sought to implant its political ideal in a more tangible reality, so that it might thereby be inspired by concrete and substantial objectives. This is one of the reasons for the existence of the dozen specialized agencies created by the family of the United Nations and dealing with Health, Culture, Agriculture, Finance, etc. Nuclear energy is one of these techniques. Becoming suddenly an important power factor and exploiting for itself the prestige of Science, it became the favorite domain for the growth of this new spirit, as much in its universal form in 1945 as in its more regional form which it was later to adopt. The achievements are numerous and of varying importance; they deserve te be studied carefully. (author) [French] L'organisation des Nations Unies et le nucleaire ont ete places simultanement, en 1945, au premier plan de la scene mondiale.

Devenu soudainement un facteur primordial de puissance, Cristallisant a son benefice le prestige de la Science, c'etait un terrain de predilection pour le developpement du nouvel esprit, aussi bien sous la forme universelle de 1945, que sous les formes regionales qui ont vu le jour ensuite.

    After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kWh of EDF2 and EDF3 compared with EDF1: the electric power per ton of uranium varies from 493 kW/t for EDF1 to 970 kW/t for EDF3. For this purpose the thermal power and electric power of units are changed respectively from 290 MWt for EDF1 to 1200 or 1600 MWt for EDF3 and from 28 to 250 MW. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, whose means of maintenance are increased; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 MWt, as against 3 for EDF1. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. The paper ends with a description of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDF1, EDF2 and EDF3 plant characteristics.

C'est dans ce but que les puissances thermiques et la puissance unitaire des groupes turbo-alternateurs passent respectivement de 290 MWt pour EDF1 a 1200 ou 1600 MWt pour EDF3 et de 82 a 250 MW.

    The apparatus described can be associated to various detectors used in nuclear physics, either rapid - its rise time is always under 30 nanoseconds - or slow, because of its continuous connections. Its gain can be increased very progressively from 2000 to 10 by increasing the feedback factors. The maximum permissible entry voltage, without causing any increase in the dead-time is 12 volts, whatever the value of the gain. The device is fitted with two continuous exits giving signals of equal amplitude but of opposite sign (10 volt pulses followed by a 4 volt undershoot). Its controls, all accessible, make it possible to adapt the apparatus very rapidly to various measurements. It is completely transistorized and the amplifier is fitted into a RENATRAN 2/8 drawer. A gain 4 preamplifier in the same drawer makes it possible to obtain a total gain of 8000. (authors) [French] L'appareil que nous decrivons peut etre associe aux divers detecteurs utilises en physique nucleaire, rapides - son temps de montee propre est toujours inferieur a 30 ns - ou lents, du fait de ses liaisons continues.

La tension maxima admissible a l'entree, sans augmentation anormale du temps mort, est de 12 volts quel que soit le gain. L'appareil comporte deux sorties continues, delivrant des signaux d'amplitudes egales et de signes opposes (impulsions de 10 volts suivies d'un undershoot de 4 volts). Ses reglages, tous accessibles, permettent d'adapter tres rapidement l'appareil aux diverses mesures. Entierement transistorise, l'amplificateur est monte dans un tiroir RENATRAN 2/8.

    Various methods of the physics brought many informations on the nuclear elements which one can arrange some ponderable quantities, what is the case of the steady elements and some, unsteady elements, as most of natural radioelements. On the other hand, elements of shorter life duration, and notably those that are carried to an excited state, are more badly known, and one can get information to their consideration that by the mediator of the properties of the transitions that they undergo, when they give birth has best-known nuclear cash: among these transitions represent the isomeric transitions. The goal of this work is the survey of the isomeric transitions from metastable states of short period, included in the domain of the microsecond to some milliseconds. The method of the deferred coincidences has been put to the point and applied in this goal while using the advantages of the selectors to several channels, under two main aspects where the device to several channels was either a selector of time, either a selector of amplitudes. This method served to study the working of Geiger-Muller counter and to measure with precision the period of {sup 181}Ta{sup *} in of the varied experimental conditions. The adopted value is 17,2 {+-}0,2 {mu}s. This work also found an immediate practical application to the setting in evidence of very weak quantities of hafnium in zirconium, of which it constitutes a tenacious and difficult impurity to analyze by the ordinary ways.

Nuclear safety is made up of all the arrangements taken to prevent accidents occurring in nuclear facilities, these accidents would certainly involved a radiological aspect. Radiation protection is made up of all the arrangements taken to evaluate and reduce the impact of radiation on workers or population in normal situations or in case of accident. In the fifties the management of radiological hazards was based on the quest for minimal or even zero risk. This formulation could lead to call some activities in question whereas the benefits for the whole society were evident. Now a new attitude more aware of the real risks and of no wasting resources prevails. This attitude is based on the ALARA principle whose purpose is to maintain the exposure to radiation as low as reasonably achievable taking into account social and economic concerns. This document regroups articles illustrating different aspects of the radiation protection in nuclear facilities such as a research center, a waste vitrification workshop and a nuclear power plant. The surveillance of radiological impacts of nuclear sites on environment is examined, a point is made about the pending epidemiologic studies concerning La Hague complex. (A.C.) 20 refs.

  5. Aspects and Polymorphism in AspectJ

    There are two important points of view on inclusion or subtype polymorphism in object-oriented programs, namely polymorphic access and dynamic dispatch. These features are essential for object-oriented programming, and it is worthwhile to consider whether they are supported in aspect......-oriented programming (AOP). In AOP, pieces of crosscutting behavior are extracted from the base code and localized in aspects, losing as a result their polymorphic capabilities while introducing new and unexplored issues. In this paper, we explore what kinds of polymorphism AOP languages should support, using Aspect......J as the basis for the presentation. The results are not exclusive to AspectJ---aspectual polymorphism may make aspects in any comparable AOSD language more expressive and reusable across programs, while preserving safety....

  18. Historical seismicity in Morocco: methodological aspects and cases of multidisciplinary evaluation

    Within the framework of a cooperative agreement between Sofratome and the Office National d'Electricite of Morocco, the Centre National de la Recherche of Rabat, with the collaboration of the French Institut de Protection et de Surete Nucleaire, was put in charge of compiling a revised catalogue of the historical seismicity of Morocco. The method adopted calls for the participation of several different disciplines in view of situating each earthquake in its own geographical and historical context. The approach entails, during the first stage involving primarily the historian, gathering together the original sources of data and subjecting them to a critical analysis in order to assess their reliability. The second stage consists in interpreting the information so as to define those earthquake characteristics that are requisite to seismic hazard studies. This latter evaluation must be the fruit of a multidisciplinary effort. This is particularly true for earthquakes of past centuries, the observations of which are frequently incompatible or biased and accordingly need to be substantiated by referring to information of a varying nature and, wherever possible, calibrated using accurate data from recent events. In a number of instances, duplications are encountered, or lumped effects for distinct events due to calendar misreckonings, erroneous copying, or misconceptions relative to the geological or historical context. A particularly significant example of the interference of these diverse aspects is afforded by the assessment of the destructive effects in Morocco of the 1755 'Lisbon' earthquake: a method is proposed for calibrating its intensities by comparing them with those of the recent 1969 event of similar origin

    The rapid development of nuclear energy demands an urgent solution to the health problems arising from the discharge into the environment of radioactive residues produced by nuclear installations. - To be able to evaluate the risks run by the population and to fix tolerance limits for waste discharge, it is necessary to possess an exact knowledge of the course taken by the radioelements discharged, from their source until they reach man. The incorporation of radioelements in food cycles is the first risk to take into consideration. The factors involved in all stages of this transmission must be foreseen, whether they concern physical or biological media, because of their continuity and their interdependence. Finally, socio-economic and dietetic data must be collected in order that the risks and tolerance levels estimated are based on concrete and experimental rather than theoretical knowledge. The risk of nuclear accidents in the atomic industry, although very improbable, must be taken into consideration because of the seriousness of their consequences. The health problems arise in the field of professional hygiene on the one hand and in that of public hygiene on the other. In the first field the risk is two-fold and involves irradiation and contamination. The public sphere is reduced essentially to the risk of contamination by radioactive substances accidentally released in the surrounding medium. The health studies to be conducted in this field therefore include research not only on irradiation or contamination therapeutics but also on the transfer of radioelements from the accident site to man, mainly through food cycles, in their physical and in their biological components. Studies of this kind form the basis of decisions in the health field which would have to be taken in the case of an accident.

    This paper describes a new dosimetry, installed inside and outside the Pressure Vessel of CHOOZ Nuclear Power Plant of the Societe d'Energie Nucleaire Franco-Belge des Ardennes (S.E.N.A.), during its 1982-83 operation cycle. The inner dosimetry deals with a simulated capsule located under the reactor plate, and includes copper, nickel, iron, niobium, copper-cobalt, neptunium and uranium dosimeters. Its aim is to qualify the information given by the existing copper dosimetry. The spectrum used with these measurements is obtained by the 1 D ANISN Code and BIP-N 2 library. The outer dosimety is the fluence determination along the outer wall of the vessel. Two tubes, equiped by neutron dosimeters, seven meters long, were fixed along the vessel. On the median plane, the results are compared to a 2 D DOT transport calculation. Preliminary results are given which improve the vessel and specimens neutronic characterisation. (Auth.)

    2013-05-10

    Behavioural and social sciences are useful in collecting and analysing intelligence data, understanding terrorism, and developing strategies to combat terrorism. This article aims to examine the psychopathological concepts of terrorism and discusses the developing roles for behavioural scientists. A systematic review was conducted of studies investigating behavioural aspects of terrorism. These studies were identified by a systematic search of databases, textbooks, and a supplementary manual search of references. Several fundamental concepts were identified that continue to influence the motives and the majority of the behaviours of those who support or engage in this kind of specific violence. Regardless of the psychological aspects and new roles for psychiatrists, the behavioural sciences will continue to be called upon to assist in developing better methods to gather and analyse intelligence, to understand terrorism, and perhaps to stem the radicalisation process.

    The author presents successively the theoretical aspect, the experimental aspect and the applied aspect of excitations in nuclear structures. The quasi-particle random phase approximation (QRPA) tool is first described. Recent approaches on QRPA are based on the theory of the density function where the ground state and excited states are described from the same nucleon-nucleon interaction. 2 methods for measuring the collective excitations are then presented: the proton scattering that has the potentiality to investigate the evolution of magicity, the second method is in fact a new method for measuring the giant mono-polar resonance (GMP) in exotic nuclei. Nuclear reactions are considered as a compulsory step on the way from observables like cross-sections to nuclear structure. The author highlights the assets of the convolution model that can generate the optical potential from the effective nucleon-nucleon interaction and from proton and neutron densities of the nuclei involved. R-processes in nucleosynthesis and neutron stars are reviewed as applications of collective excitations in the field of nuclear astrophysics. (A.C.)

    The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of competition and the characteristics of goods. Moreover, bundling can be used as price discrimination tool, screening device or entry barriers. In monopoly case bundling strategy is efficient to sort consumers in different categories in order to capture a maximum of surplus. However, when competition increases, the profitability on bundling strategies depends on correlation of consumers' reservations values. (author)

    The quality of a conventional radiographic image can be characterized in terms of five basic parameters; density, contrast, latitude, resolution and noise. Since xeroradiographic images exhibit very limited broad area contrasts, and image formation is predominantly due to edge enhancement, a straightforward description of image quality using the same five parameters is not adequate. A detailed study was made of the radiographic aspects of xeroradiography with special reference to mammography, and a summary of major findings to date with appropriate references to published papers is presented

    The development of new surgical techniques, of new prosthetic materials, and the increase in life expectancy with greater coverage of health services has ugmented the performance of hip replacements in our country. The radiologist should be familiar with the different surgical techniques and prosthetic devices, the evaluation of its components and associated complications. The most frequently performed arthroplasties are: shoulder, elbow, hip and knee replacement. This article reviews the most frequent prosthetic devices used, the radiological aspects of arthroplasties and their most common complications.

    Eckert, J; Thompson, R C A

    2017-01-01

    Echinococcosis is a zoonosis whose history dates back to antiquity. This article provides an overview on the general history of echinococcosis, including the elucidation of Echinococcus life cycles and the long controversy on the aetiology of the cystic and alveolar forms of echinococcosis (CE and AE), lasting about 100years since the middle of the 19th century. Furthermore, selected historical aspects of some fields of echinococcosis research are discussed and compared with our current knowledge, such as geographic distribution and epidemiology of CE (Echinococcus granulosus) and AE (Echinococcus multilocularis), clinical aspects and pathology, diagnosis in humans and animals, treatment (with focus on chemotherapy), control and basic research. A short paragraph is devoted to the neotropical forms of echinococcosis, caused by Echinococcus vogeli and Echinococcus oligarthrus. In this context the achievements of some ancestral pioneers of echinococcosis research are particularly highlighted and appreciated. Finally, the role of associations, international organizations (World Health Organization and others) and international working groups in echinococcosis research and control is briefly outlined. The retrospective reveals both the admirable achievements of our ancestors and the scientific progress of more recent times. But, it also shows the gaps in our knowledge, skills and resources that we need to control or even eradicate echinococcosis. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2006-11-01

    This study was undertaken to consider the psychological aspect of diabetes with regard to improving clinical outcomes. The review was limited to literature reports on the causes, solutions, and treatments of some common psychological problems known to complicate diabetes management. A literature search was undertaken using Pub-Med, CINAHL, Proquest, Elsevier, Blackwell Synergy, Ovid, Ebsco, Rose net, and Google websites, including studies published in English journals between 1995 and 2006. Therefore about 88 articles were selected based on the inclusion criteria. In earlier studies, relatively little empirical research was found to substantiate the effect of psychological counseling in complicated diabetes. The greatest deficits were seen in areas of mental health, self-esteem parent impact, and family cohesion. There were some different factors, which influence the psychological aspect of diabetic patients, such as age, gender, place of living, familial and social support, motivation, energy, life satisfaction, and lifestyle. There are various types of solutions for coping with the psychological problems in diabetic clients. The most essential solution lies in educating the patients and healthcare providers on the subject. Before initiating each educational intervention, a thorough assessment would be crucial. Treatment plans may benefit from cognitive behavior therapy (CBT), behavior family therapy, improving family communication, problem-solving skills, and providing motivation for diabetic patients. Moreover, it seems that the close collaboration between diabetologists and psychologists would be fruitful.

    Full Text Available In the process of globalization of world economic processes, the role of individual national economies increases, comparative advantages of the development of a country are formed, and their competitiveness is ensured. That is why it is worth emphasizing the importance of increasing the competitiveness of each individual country, based on its internal capacity. In a broad aspect, the competitiveness of the national economy is perceived as the ability of the country to ensure the balance of its external proportions and to avoid those constraints imposed by the foreign economic sphere, to self-organizing the improvement of their world economic ties. The competitiveness of the economy at the macro level is associated with the duration of the cycle of reproduction of the main productive assets and, accordingly, the jobs, productive forces of society and determined by the overall economic efficiency of investment. The criteria of competitiveness of the national economy are the growth of social productivity of labor, increase of social and economic efficiency of production and standard of living of the population. The competitiveness of the national economy determines sustainable socio-economic development of the country, as well as sustainable development predetermines the competitiveness of not only the country, but also all its levels. Scientific results are obtained using special methods of research of economic objects and phenomena, that is, based on the correlation and regressive, comparative analysis (establishing the relationship between the indicator factor, as well as economic modeling. Findings. Generalizing analysis and the importance of the macroeconomic aspect of competitiveness were used in the research paper, which will allow to better respond to the economic situation, in accordance with the trends of the “green” transformation of the economy; which in turn will solve important problems of the development and implementation of its

    2010-10-01

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    1997-01-01

    The political and socio-economic aspects of oil and gas exploration in Canada's Arctic and the Beaufort Sea were reviewed. The federal government was very interested in developing the North because they saw oil and gas development in the North as a means of strengthening sovereignty claims. The projected profits from Northern oil and gas development were also very attractive, and after dealing with environmental and social concerns, the government granted the necessary drilling permits. The federal government also made allowances for huge tax incentives for the oil and gas companies to encourage exploration. Although oil has been found, large-scale production in the Beaufort Sea never materialized. During the period from 1984 to 1988, world prices for oil fell and it was no longer economical to undertake frontier production. Beaufort Sea operation were shut down as the oil industry changed its focus to more cost-effective reservoirs in southern Canada. 1 fig

    1997-01-01

    Beside the technical problems of ADTT which remain to be solved it is crucial for the ADTT progress that safety and economical aspects are considered already during the research and planning phases. Safety here stands for the converse of risk, negative consequences for human life and health and the environment together with the corresponding probabilities. The system to be considered includes all phases of an ADTT plant, a life cycle analysis (LCA). The risk analysis is useful for two purposes: comparison with other ways of handling nuclear waste, e.g. geological repository and for valuation of different construction designs. Due to lack of precise plans and adequate data the analysis will be more of a qualitative than quantitative type. The main risks appear in connection with repair and replacement work. 2 refs., 1 fig

    Full Text Available The concept of resilience has represented during the recent years a leading concern both in Romania, within the European Union and worldwide. Specialists in economics, management, finance, legal sciences, political sciences, sociology, psychology, grant a particular interest to this concept. Multidisciplinary research of resilience has materialized throughout the time in multiple conceptualizations and theorizing, but without being a consensus between specialists in terms of content, specificity and scope. Through this paper it is intended to clarify the concept of resilience, achieving an exploration of the evolution of this concept in ecological, social and economic environment. At the same time, the paper presents aspects of feedback mechanisms and proposes a formalization of resilience using the logic and mathematical analysis.

    What do combustion engines, fusion reactors, weather forecast, ocean flows, our sun, and stellar explosions in outer space have in common? Of course, the physics and the length and time scales are vastly different in all cases, but it is also well known that in all of them, on some relevant length scales, the material flows that govern the dynamical and/or secular evolution of the systems are chaotic and often unpredictable: they are said to be turbulent. The interdisciplinary aspects of turbulence are brought together in this volume containing chapters written by experts from very different fields, including geophysics, astrophysics, and engineering. It covers several subjects on which considerable progress was made during the last decades, from questions concerning the very nature of turbulence to some practical applications. These subjects include: a basic introduction into turbulence, statistical mechanics and nonlinear dynamics, turbulent convection in stars, atmospheric turbulence in the context of nume...

    Full Text Available Customer loyalty - is a voluntary user solution for a long time to build relationships with the company. Loyalty is the user's desire for a long time to continue their relationship with a particular company, because loyal customers are those who purchase goods/services of the company from time to time. Loyalty can be treated as a customer desire, willingness to be a regular customer for a long time, buying and using the goods of the chosen companies by recommending them to friends and colleagues. Loyalty can be seen as a multi-dimension, covering behavioral and positional components, where positional aspect reflects customers' approach to business, while the behavioral dimension reveals a frequent and regular shopping, purchase quantity, size, range, availability, etc.

    1996-01-01

    The complexity of the decisions to be taken by the radiation protection and safety authorities in the nuclear, medical, and industrial fields, as well as the importance of the risks involved, require consideration of the confidence that the public can have in the procedures and institutions associated with these decisions. The Technical Support Organisations that advise these authorities play an essential role in risk evaluation. They participate both in defining the scientific bases of the regulations and analysing the authorization request from the operators. The credibility of these bodies implies a clear separation between their function and that of the regulatory authorities and the operators. It also requires a guarantee of competence which is based on a high level research program and contacts with other similar organisations. The quality of the work carried out by the Technical Support Organisations must be regularly evaluated. One of the most important of the other conditions for ensuring the effectiveness of the expertise is its integration in a well defined decision-making procedure. The author has based this article on his experience as director of radiation protection in the IPSN (Institut de Protection et de Surete Nucleaire), an organisation formed in 1976, with a staff of 1,200 whose functions are to carry out research and provide expertise in health physics radioecology and nuclear safety. To reinforce its operating autonomy and authority, the status of the IPSN was thoroughly revised as strengthened in 1990. (Author)

    Pain is defined "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage". Pain is a sensation of the body, and is always an unpleasant emotional experience. The role of psychology is auxiliary and supplemental to medicine. This is an aid addressed to the patient, physician and patient's caregivers: professional caregivers, family members and significant others. At each stage of the diagnostic and therapeutic process, psychology offers help, both from the cognitive and practical aspects. The objective of the article is to present important psychological aspects of studies concerning pain, and the psychological methods and techniques of pain treatment. Pain is the leading reason for patients seeking medical care and is one of the most disabling, burdensome, and costly conditions. Pain accompanies many diseases, each one of which generates unique/separate diagnostic, therapeutic and research problems. DEPRESSION AND RELATED PSYCHICAL DISORDERS: There is a significant relationship between depression and pain symptoms, as well as between pain and suicidal thoughts. Patients with a long history of pain disorders also have increased depression and anxiety symptoms, as well as suicidal thoughts. Patients with more severe depression and anxiety symptoms also have an increase in pain problems. The intensity of pain correlates with the intensity of psychopathological symptoms - both with mood lowering and with anxiety symptoms and worry. Active pain coping strategies strive to function in spite of pain, or to distract oneself from pain, are associated with adaptive functioning. Passive strategies involve withdrawal or relinquishing control to an external force or agent and are related to greater pain and depression. Pain catastrophizing is a negatively distorted perception of pain as awful, horrible and unbearable. Catastrophizing is strongly associated with depression and pain. Studies in which

    2016-12-01

    Full Text Available Innovation in assisted reproductive technologies together with increased infertility and new family structures are increasing the use of gestational surrogacy as a means to have children. Before, during and after the process, it is necessary to study the psychosocial characteristics of triad members: the gestational surrogate, intended parents, and offspring. Research has indicated positive adaptation to the process and benefits for all members of the triad. Altruism is the main motivation of surrogates. Notably, psychological well-being has been found to be higher in individuals who have become parents through surrogacy than in those who have used egg donation or have followed a natural process of conception. Moreover, no differences in psychosocial characteristics have been observed in the offspring, compared with children born through natural conception or egg donation. Results highlight the positive aspects of surrogacy. Future research should investigate psychosocial factors that modulate the process, acting as risk and protective factors for well-being of the triad members, and identify the optimal profiles of surrogates for the process to be a success.

  20. Electrical aspects of rainout

    International Nuclear Information System (INIS)

    Rosenkilde, C.E.

    1981-01-01

    Rainout commonly denotes the aggregate of phenomena associated with precipitation scavenging of radioactivity from a cloud of nuclear debris that is within a natural rain cloud. (In contrast, the term, washout, is applicable when the nuclear cloud is below the rain cloud and the term, fallout, commonly denotes the direct gravitational settling of contaminated solid material from a nuclear cloud.) Nuclear debris aerosols may be scavenged within natural clouds by a variety of different physical processes which may involve diffusion, convection, impaction, nucleation, phoresis, turbulence, and/or electricity among others. Processes which involve electrical aspects are scrutinized for their susceptibility to the intimate presence of the radioactive-cloud environment. This particular choice of electrical processes is not accidental. Nearly all of the listed processes were examined earlier by Williams. His rough estimates suggested that electrical effects, and to a lesser extent turbulence, could enhance the scavenging of those submicron aerosols which reside in the size-range that bridges the minimum in the scavenging rate coefficient which is commonly called the Greenfield gap. This minimum in the scavenging-rate coefficient is created by the simultaneous reduction of scavenging via diffusion and the reduction of scavenging via inertial impaction. However, Williams omitted the specific influence of a radioactive environment. This report aims to remedy this omission

    2016-01-01

    Full Text Available The paper considers risk in the context of the main characteristics of non-classical epistemology. It states that non-classical epistemology is characterized by transformation, according to which the major priority of cognitive activity shifts the focus from the present to the past. In this situation a subject is keen not on what he or she has learnt but on what can be learnt. Truth being a crucial criterion of scientific knowledge is becoming of less priority, while risk is becoming more and more significant and acts as one of the major epistemology measurements. Risk is gaining the status of epistemological phenomenon, which shows a growing degree of uncertainty as a cognitive process background and the necessity for a subject to learn the world (make decisions under the conditions of uncertainty degree strengthening. The author states that risk is a comprehensive notion and it obtains a base value for all other aspects of its application, specifically, in the role of epistemological phenomenon.

    2005-09-08

    Undefined cultural factors cannot be dismissed and significantly contribute to the worldwide incidence of death by suicide. Culture is an all embracing term and defines the relationship of an individual to his environment. This study seeks to investigate the effect of culture on suicide both regionally and internationally. Culture-bound syndrome with suicidal behaviours specific to a particular culture or geographical region are discussed. Opinions are divided as to the status of religious martyrs. The law itself is silent on many aspects of suicidal behaviour and despite decriminalization of suicide as self-murder, the latter remains on the statutes of many developing countries. The Caribbean region is of concern due to its steady rise in mean suicide rate, especially in Trinidad and Tobago where socio-cultural factors are instrumental in influencing suicidal behaviour. These include transgenerational cultural conflicts, psycho-social problems, media exposure, unemployment, social distress, religion and family structure. The methods used are attributed to accessibility and lethality. Ingestion of poisonous substances is most popular followed by hanging. The gender differences seen with regard to suicidality can also be attributed to gender related psychopathology and psychosocial differences in help-seeking behaviour. These are influenced by the cultural environment to which the individual is exposed. Culture provides coping strategies to individuals; as civilization advances many of these coping mechanisms are lost unclothing the genetic predisposition of vulnerable groups. In the management of suicidal behaviour, a system of therapeutic re-culturation is needed with an emphasis on relevant culture- based therapies.

    Full Text Available Infertility can be defined as a crisis with cultural, religious, and class related aspects, which coexists with medical, psychiatric, psychological, and social problems. Relation between psychiatric and psychological factors stem from a mutual interaction of both. Family is an important institution in maintaining human existence and raising individuals in line with society's expectations. Fertility and reproduction are seen as universal functions unique to women with raising children as the expected result of the family institution. Incidence of infertility has increased recently and can become a life crisis for a couple. Even though not being able to have a child affects both sexes emotionally, women feel greater amounts of stress, pressure, anxiety, and depression.Consequences of infertility arise from short and long-term devastating effects on both individual's physical and mental health, and marital system. Many studies focus on infertility related psychological and psychiatric disorders (depression, anxiety, grief, marital conflict, gender differences, relation between the causes of infertility and psychopathology, the effects of psychiatric evaluation and intervention -when necessaryon the course of infertility treatment, pregnancy rates, and childbirth. The most important underlying causes of high levels of stress and anxiety that infertile women experience are the loss of maternity, reproduction, sense of self, and genetic continuity. In this review article is to investigate the relationship between medically unexplained symptoms and psychiatric symptoms.

    Precise computation of neutron flux in the core of a nuclear reactor represents one of the basic aspects of reactor design and operation. Neutron flux is computed by solving Boltzmann`s linear equation. Anyway, the direct solution of the equation involves too great a number of operations for practical application, leading up to TeraFlops or even PetaFlops supercomputing capabilities. Physical and mathematical models are then required to handle the extensive variety of configurations encountered. Numerical methods must be adapted to the rapid evolution of computer power, as also computer architecture: sequential, vector or parallel. Physical and mathematical models must allow for very fast estimation for online control and monitoring, adequate quantification for industrial studies and high-precision, best estimate computations. Coupling of neutronics to mechanics and two-phase flow thermohydraulics must be implemented in order to improve the accuracy in best-estimate computation schemes and to take into account the transient behaviour of the plant during normal operation or incidents. In this field of continuous improvement, the new methods applied in Reactor Physics lead obviously to good results and provide the improvements required in the future for the needs of efficiency, safety and advanced fuel cycle. This trend and the ``evolutionary`` implementation in large and modular software systems will be illustrated by the example of the SAPHYR system. (authors). 3 tabs.

    At a time when the nuclear question mobilizes attentions and when a new cycle of debates about non-proliferation opens up, the author recalls the constraints and challenges of a nuclear power generation policy. After a brief history of the development of nuclear energy in France and in the rest of the world, the author presents the risks linked with this energy source (TMI and Chernobyl accidents), the particularities of the fuel cycle with its safety and security aspects, and the promises of some past and future reactor technologies (FBR's and fusion reactors). Then, the author stresses on the importance of investments in this domain as illustrated by the launching of new nuclear programs in France, UK, Italy, Finland and in the US, and by the willing of some emerging countries to develop this energy source (China, India, United Arab Emirates, Jordan..). Finally, nuclear energy must not be considered as a privilege of developed countries but should benefit to the rest of the world as well since it promotes economic development thanks to an abundant and cheap energy.

    Kostić Aleksandar V.

    2013-01-01

    Full Text Available The author examines futurological aspects of globalization having in mind various models of historical processes. He describes the changes as "futuroshock", thus presenting a dilemma whether the changes are only a momentum or a pre-planned concept. He especially stresses the Toffler’s conclusion that turns a new page in futurology - examining the dangers that follow the changes. According to him, predictions are made with the help of practically all the sciences in two basic directions: exploratory and normative. In his work the author considers the problem of the future not having perspective as a sequel to the present. The idea to build the world as a dualistic society of the "golden billion" and the exploited crowd is but new kind of fascism. In his opinion it is necessary to answer the question of who will indicate the qualitatively distinctive future and by which means this will be achieved. The traditional western science considers an anomaly everything that deviates a bit from it. Such a scientific paradigm projects conflicts, war, violence, which was the case in Yugoslavia, Iraq, Afghanistan, Libya, Syria etc. The author asserts three hypotheses of the possible future world order, while noticing that globalization transforms the whole regions into neo-totalitarian version of the order that spreads in concentric circles on the most of the world. According to the author, global totalitarian government is responsible for dual moral and double standards that provide limitless freedom for themselves and just the opposite for others. Within the given context, the conditions are being created on the East for a unique bloc that will consist of Chinese, Russian and Hindu-Buddhist civilization. This will serve as an alternative to the aggressive West.

    Full Text Available One of the most important conditions of the existence of every organization, every enterprise is to insure the long-term sustainable development, one of the conditions of which is the increase of an organizational competitiveness. In modern economic conditions, social aspects of competitiveness are now in the foreground of interest, because just the strategy of social responsibility (SSR of modern enterprises can assure some commercial benefits, in responding, at the same time, to the social demands and in creating its well-being. Such an approach is in the basis of the notion of competitiveness. Along with «rigid parameters», such as price characteristics, the capability to deal with competitors, effective financial and production policies, «flexible factors» of competitiveness are of a big importance: a personnel potential, individual and collective competencies, organizational and managerial capabilities. As a result, we have formulated a research hypothesis: the organizational competitiveness is defined by individual and collective competencies of an organization, is based on socially responsible actions, confirms the demand for the object and insures its sustainable long-term development. Any organization should base all its actions aimed to increase its competitiveness on its intellectual potential, or on the management of individual and collective competencies that assure the sustainable development and the goal achievement. For every organizational strategic action, an effective combination of these competencies exists. So, we suggest a new definition of competitiveness: it is a social and economic category of understanding of the social responsibility, having as a central element individual and collective competencies, based on socially responsible actions of an enterprise, insuring its long-term sustainable development.

The experimental results show that, for an instantaneous neutron fast flux of 10{sup 13} n cm{sup -2} sec{sup -1}, an equilibrium is attempted, after several days, for a part lower than 20 per cent of the quantity of He formed, theoretically calculated from the neutron cross sections of nuclear reactions, and from the analytical form of the neutron fast flux, releases from the solid. The validity of the values of calculated helium and the gas chromatographic analytical method are also verified by dissolution of the BeO pellets in cryolite. A new fast neutron flux measuring method may be so defined. The discussion of the experimental results enables to establish that the processus of He release is characterized by two phenomena: the first one which controls the release of He atoms out of the solid and the second which reveals a capture processus, connected to the irradiation and probably due to the vacancies induced in the lattice.

    The Large Aspect Ratio Tokamak Study (LARTS) at Oak Ridge National Laboratory (ORNL) investigated the potential for producing a viable longburn tokamak reactor by enhancing the volt-second capability of the ohmic heating transformer through the use of high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

    Adverse effects of benzodiazepines are well known since the first one was used in 1958 (chlordiazepoxide). The literature collects study-cases or rarely controlled studies concerning side effects or paradoxical reactions to benzodiazepines. They mostly described drowsiness and behavioral disinhibition, including increased well-being feeling but also hostility, rage access with feeling of invulnerability, serious crimes and sometimes homicides. Delusional, manic, confusional or depressive states are also pointed out. Rate for aggressive behaviour is 0.3 to 0.7% but distinction should be done between accidental or "idiosyncratic" reaction and voluntary sought disinhibition, clearly more frequent. No benzodiazepine has any specificity for these adverse effects but pharmacology, doses, associated drugs (or alcohol) and psychopathology interact to produce hazardous psychic states. Pharmacology: GABA induces a decrease in serotonin compound and vigilance. Pharmacokinetic: first dose effect or over-dose effect, short half-life, lipophily, affinity, digestive absorption, active metabolites interact. Psychopathology: age, alcohol association, psychological status (high initial level of hostility, impulsivity, frustration, personality disorder and depressive status). External conditions: chronic illness, affective and professional frustrations, physical or psychic exhaustion contribute also. Some benzodiazepines (flunitrazepam, diazepam, clorazepate, triazolam, alprazolam, lorazepam, for example) are more often concerned for pharmacokinetics characteristics but also prescription habits. Forensic aspects should be considered in case of homicide. Especially, reality of benzodiazepines consumption and awareness of the potential paradoxical reaction should be precisely evaluated. Special focus on voluntary induced disinhibition has to be done for forensic considerations. Relationship but also crime facilitations are sometimes consciously sought. Some benzodiazepines have already

    It is widely recognised that global energy demand will rise substantially during this century. The increased industrialization and urbanization of developing countries will produce large increases in energy demand in regions that currently have very low per capita energy use. This increasing demand for energy will need to be met in order to improve living standards for at least half of the world population and to reduce the economic imbalances between countries and regions. At the same time the use of fossil fuel based energy is identified as a major cause of environmental damage. The release of greenhouse gases from burning of fossil fuel in power stations and for transport is seen as a contributor to global warming. It is widely recognised that continued exploitation of fossil fuels and release of carbon dioxide will need to be controlled. After a prolonged period of slow development of nuclear power, confined to some countries in the world, it is now being recognised that nuclear energy has a potentially significant role to play in meeting the energy needs of the planet without damaging the environment. Developments in technology make the economics of nuclear power more attractive, and they may become even more so as fossil fuel prices continue to rise.or a widespread use of nuclear power, however, there remain concerns on the safety, security, waste and proliferation aspects. The global application of safety standards and appropriate security measures are required to ensure acceptable levels of protection. Effective control measures are required to ensure that non-proliferation commitments are honored. Handling nuclear waste safely and securely is achievable, but continues to remain as a public concern. The broad strategic objectives of the Conference are the following: to review the role of nuclear power and to define the potential benefits (energy security, sustainability and improved environmental protection) that expanding nuclear power offers to meet the

    This report presents a snapshot of nuclear safety and radiation protection conditions in the AREVA group's nuclear installations in France and abroad, as well as of radiation protection aspects in service activities, as identified over the course of the annual inspections and analyses program carried out by the General Inspectorate in 2006. This report is presented to the AREVA Supervisory Board, communicated to the labor representation bodies concerned, and made public. In light of the inspections, appraisals and coordination missions it has performed, the General Inspectorate considers that the nuclear safety level of the AREVA group's nuclear installations is satisfactory. It particularly noted positive changes on numerous sites and efforts in the field of continuous improvement that have helped to strengthen nuclear safety. This has been possible through the full involvement of management teams, an improvement effort initiated by upper management, actions to increase personnel awareness of nuclear safety culture, and supervisors' heightened presence around operators. However, the occurrence of certain events in facilities has led us to question the nuclear safety repercussions that the changes to activities or organization on some sites have had. In these times of change, drifts in nuclear safety culture have been identified. The General Inspectorate considers that a preliminary analysis of the human and organizational factors of these changes, sized to match the impact the change has on nuclear safety, should be made to ensure that a guaranteed level of nuclear safety is maintained (allowance for changes to references, availability of the necessary skills, resources of the operating and support structures, etc.). Preparations should also be made to monitor the changes and spot any telltale signs of drift in the application phase. Managers should be extra vigilant and the occurrence of any drift should be systematically dealt with ahead of

    To date studies of halo nuclei have been principally focussed on the A 11 systems {sup 11}Li and {sup 11}Be. The evolution of the properties of the halo with the mass of the system and the binding energy and angular momentum of the halo nucleons is a question of fundamental importance. It was in this spirit that the present study of {sup 19}C (S{sub n} = 240 {+-} 100 keV) was undertaken. The experiment was performed at GANIL using a secondary {sup 19}C beam ({approx_equal} 15 pps at 36 MeV/nucleon) produced via fragmentation. The experimental setup which included the neutron array DEMON, provided for identification of the core-breakup and dissociation reaction channels. In the first case, a very narrow single neutron angular distribution (FWHM = 64 {+-} 17 MeV/c) was observed for {sup 19}C, in contrast to that found for three `reference` nuclei {sup 21}N, {sup 22}O and {sup 24}F (FWHM {approx_equal} 165 MeV/c). This result could be interpreted within the framework of the core-breakup reaction model of a one-neutron halo nucleus. The results obtained for dissociation, while supporting the existence of the halo, indicated that it is not well developed. In addition, a comparison between the present results, the parallel momentum distributions for the core ({sup 18}C) and theoretical predictions have allowed conclusions to be drawn regarding the configuration of the valence neutron. In particular, a purely 2s{sub 1/2} of 1d{sub 5/2} configuration is excluded and mixing, possible with core excited states, must be considered. A probable ground state spin-parity assignment of 3{sup +}/2 or 5{sup +}/2 is suggested. (author) 150 refs., 278 figs., 28 tabs.

    The French Decree dated December 13, 1999 transposing the Pressure Equipment Directive (PED) has replaced the fundamental texts on which up to now the regulation for pressure equipment important for the safety of nuclear reactors was also founded. By a Ministerial Order - called 'ESPN Order' - dated December 12, 2005, a new regulation has been issued for nuclear pressure equipment. This text makes reference to the Decree transposing the PED while completing these provisions by supplementary requirements having the objective to provide a very high level of integrity guarantee for equipments which are the most important for safety, and to cover the prevention of radioactive release risks. These regulatory evolutions are presented in the Plenary Session of the ESOPE conference. Referencing the Decree and thus the PED, and including specific provisions, the Ministerial Order implies that the Manufacturers update their documents and, if necessary, their prescriptions in the following two domains: - that of the conformity of Codes and Standards used, generally inspired from the ASME Code Section III, with the essential safety requirements of the PED, - that of the respect of the complementary provisions brought by the ESPN Order. This paper presents the more significant conclusions of this work and the resulting amendments of the RCC-M Code, introduced by the 2007 addendum to that Code. The analysis will lead to specify the same type of complementary requirements to Code when a manufacturer wishes to use the German KTA Rules or the ASME Code Section III.

The gonadal maturation of M. auriculatus was examined by means of macroscopic and histological preparations of the mantle. Annual cycle with periods of growth, maturity and discharge of gonadic products occurs simultaneously in both sexes. Ripe individuals were observed throughout the year. The largest number of spawning for the individuals occurred from March to June and July for the population. So, it was clear to identify one heavy spawning period for this species. Sexation of M. auriculatus did not differ significantly from 1:1. Sexes were distinguishable in all individuals at the ripe stage with a shell length greater than 3.00 cm. A direct positive correlation was observed between gonad index and water temperature.

    The economic advantage of electricity-generating nuclear stations decreases when their size decreases. However, when a counter-pressure turbine is joined on to a reactor and the residual heat can be properly used, it can be shown that fairly low capacity nuclear equipment may compete with conventional equipment under certain realistic enough conditions. The aim of this paper is to define these special conditions under which nuclear energy can be profitable. They are connected with the location and the general economic environment of the station, the pattern of the electricity and heat demands it must meet, the level of fuel and specific capital costs, nuclear and conventional. These conditions entail certain technical and economic specifications for the reactors used in this way otherwise they are unlikely to be competitive. In addition, these results are referred to the potential steam and electricity market, which leads us to examine certain uses for the heat generated by double purpose power stations; for example, to supply combined industrial plants, various types of town heating and for removal of salt from sea water.

    The present paper, based on the results of international studies, is focused on the reconsideration of the psychological aspects of induced abortion. By presenting a narrow cross-section of the Hungarian demographic data, we would like to emphasise the necessity and the significance of a deeper understanding of the subject. Factors behind the decision-making, short- and long term outcomes of the intervention influencing primarily the mental health of women and partner-relationship aspects are discussed in details. While acknowledging the complexity of the subject deriving from the legal, ethical, moral, religious, medical, social and sociological concerns, our aim is to call attention to the psychological aspects of induced abortion and the importance of psychological care of women undergoing surgical operation.

    The apparatus studied is a digital calculating assembly which makes it possible to prepare and to present numerically the period and power of a nuclear reactor during operation, from start-up to nominal power. The pulses from a fission chamber are analyzed continuously, using real time. A small number of elements is required because of the systematic use of a calculation technique comprising the determination of a base 2 logarithm by a linear approximation. The accuracy obtained for the period is of the order of 14%; the response time of the order of the calculated period value. An approximate value of the power (30%) is given at each calculation cycle together with the power thresholds required for the control.

    Corrosion of aluminium in contact with moderating water in nuclear reactor leads to the formation of an alumina hydrosol which can have an adverse effect on the operation of the reactor. Several physical methods have been used in an attempt to counteract this effect. The method proposed here consists in the elimination of the aluminium by dissolution and subsequent fixation in the ionic form on mixed-bed ion-exchange resin. In order to do this, the parameters and the values of these parameters most favorable to the dissolution process have been determined. If the moderator is heavy water, the deuterated acid can be prepared by converting a solution in heavy water to a salt of the acid using a deuterated cationic resin. (author) [French] La corrosion de l'aluminium au contact de l'eau moderatrice des reacteurs nucleaires, donne lieu a la formation d'un hydrosol d'alumine nuisible au bon fonctionnement des reacteurs. Plusieurs methodes physiques ont ete mises en oeuvre pour pallier ces inconvenients. On propose ici d'eliminer l'alumine par solubilisation pour la fixer ensuite sous forme ionique par des resines echangeuses d'ions, en lit melange. A cette fin on determine les parametres et leurs grandeurs favorables a cette solubilisation. Si le moderateur est de l'eau lourde la preparation d'acide deutere peut etre effectuee par passage d'une solution en eau lourde a un sel de l'acide sur resine cationique deuteree.

    Due to the unusually large zero point motion of helium three atoms in the solid, the overlap of the atomic wave functions is very important. As a consequence, there are exchange interactions, the theoretical calculation and the experimental measurement of which are discussed. Nuclear magnetic resonance is especially well suited for the latter.A detailed theory is given for both exchange narrowing and Zeeman-exchange cross relaxation, which phenomena are used to measure the exchange interaction as a function of molar volume. The alignment temperature is thus known; it goes down when the pressure goes up and is never higher than three milli degrees. An influence of helium four impurities on the exchange interactions between helium three atoms which are neighbours of the substitutional He is shown. (author) [French] Par suite de l'amplitude exceptionnelle des mouvements de point zero dans l'helium trois solide, le recouvrement des fonctions d'onde atomiques est tres important. Il en resulte des interactions d' echange dont on discute l'evaluation theorique et la mise en evidence experimentale. Cette derniere peut se faire par resonance magnetique; on etudie theoriquement les phenomenes de retrecissement par echange et de relaxation Zeeman-echange que l'on met a profit pour determiner les interactions d'echange en fonction du volume molaire. On en deduit que la temperature d'alignement nucleaire diminue quand on comprime le solide et est au plus de 3x10{sup -3} K. L'influence des impuretes d'helium quatre sur les interactions d'echange entre atomes {sup 3}He voisins de {sup 4}He est mise en evidence. (auteur)

    This work studies some aspects of the computational power of fully asynchronous cellular automata (ACA). We deal with some notions of simulation between ACA and Turing Machines. In particular, we characterize the updating sequences specifying which are "universal", i.e., allowing a (specific family of) ACA to simulate any TM on any input. We also consider the computational cost of such simulations.

    2003-01-01

    In this lecture, we present selected aspects of nuclear fusion. The importance of the initial geometry of the reaction and its relation to fusion barrier are first discussed. The effect of deformation leading to the notion of barrier distribution is then illustrated. After a brief overview of the advantages of macroscopic theories, the dynamics of nuclear system under large amplitude motion is reviewed. The di-nuclear concept is presented to understand the competition between fusion and quasi-fission. This concept is then generalized to account for the dissipative dynamics in multidimensional collective space. The last part of this lecture is devoted to new aspects encountered with radioactive beams specific properties of very extended neutron rich system, influence of pygmy or soft dipole resonances and charge exchange far from stability are discussed.

  12. The psychological aspects of rhinoplasty.

    Science.gov (United States)

    Tasman, Abel-Jan

    2010-08-01

    Literature on the psychological aspects of rhinoplasty is sparse compared with publications on methods and instrumentation. Understanding the psychological aspects of rhinoplasty and, more importantly, recognizing the patient who may have an unfavorable postoperative course regardless of the objective outcome is of fundamental importance to the surgeon. Several profiles of patients with a high risk of postoperative dissatisfaction have been described and the important role of body dysmorphic disorder and its treatment has been stressed. Still, these criteria can be insufficient when facing the individual patient, as reliable screening instruments for clinical practice have not been developed and the question when not to operate is subject to controversy. The role of computer imaging as a safeguard in preoperative counseling has been highlighted. The surgeon must rely on instinct and experience to avoid overlooking any signs of psychological imbalance in the patient that may herald adversity. Archetypes described in the literature should be recognized and computer imaging should be used during the preoperative consultation.

    In Phebus (French in pile facility; PWR scale 1/5000) experiments, performed by the Institut de Radioprotection et de Surete Nucleaire, few quantities of organic iodides were registered after interaction between iodine and reactor containment paint. This study concerns all mechanisms of chemical reactions between iodine and the polymer of the paint in order to estimate the organic iodides released from the paint. At first, all the paint components had been identified. Several models of chemical sites of the polymer were synthesized and tested with iodine in different conditions of temperature and radiation. These experiments showed interactions between iodine and secondary or tertiary amines by charge transfer. In few cases, the complex of tertiary amines creates oxidation reactions. (author)

    Full Text Available SUMMARY This literature review analyzed the evidence on nutritional aspects related to the pathogenesis and progression of endometriosis. Diets deficient in nutrients result in changes in lipid metabolism, oxidative stress and promote epigenetic abnormalities, that may be involved in the genesis and progression of the disease. Foods rich in omega 3 with anti-inflammatory effects, supplementation with Nacetylcysteine, vitamin D and resveratrol, in addition to the increased consumption of fruits, vegetables (preferably organic and whole grains exert a protective effect, reducing the risk of development and possible regression of disease. Dietary re-education seems to be a promising tool in the prevention and treatment of endometriosis.

    Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

    2012-11-01

    In the UK schools are required by law to protect students from bullying; the responsibility of teachers to govern such behaviour has been extended outside the school setting to include cyberbullying. In this investigation, cyberbullying in secondary education is explored from the student perspective using a qualitative method of enquiry. Reported awareness and understanding about the legal aspects of cyberbullying are investigated; consideration is given to legislation, cybercrime, children's rights, school sanctions and safeguarding responsibilities. A total of 197 male and female students aged between 11 and 14 years old participated. Despite the availability of information on guidelines and legislation at national, local, and school level, this does not appear to have reached ground level of the individual student. There is a considerable gap between what students should know and what they report to be aware of with regard to legal aspects of cyberbullying. To address concerns of keeping up with the pace of change in cyberbullying, a collaborative approach is required with young people and adults sharing expertise.

    2012-01-01

    Full Text Available Introduction. Considered as a rare event, gastric syphilis (GS is reported as an organic form of involvement. Low incidence of GS emphasizes the importance of histopathological analysis. Objective. We aim to characterize GS endoscopic aspects in an immunocompetent patient. Case Report. A 23-year-old man presented with epigastric pain associated with nausea, anorexia, generalized malaise and 11 kg weight loss that started 1 month prior to his clinical consultation. Physical examination was normal except for mild abdominal tenderness in epigastrium. Endoscopy observed diminished gastric expandability and diffuse mucosal lesions, from cardia to pylorus. Gastric mucosa was thickened, friable, with nodular aspect, and associated with ulcers lesions. Gastric biopsies were performed, and histopathological analysis resulted in dense inflammatory infiltration rich in plasmocytes. Syphilis serologies were positive for VDRL and Treponema pallidum reagents. Immunohistochemical tests were positive for Treponema pallidum and CD138. The patient was treated with penicillin, leading to resolution of his clinical complaints and endoscopic findings. Conclusion. Diagnosis suspicion of GS is important in view of its nonspecific presentation. Patients with gastric symptoms that mimic neoplastic disease should be investigated thoroughly based on the fact that clinical, endoscopic, and histological findings can easily be mistaken for lymphoma or plastic linitis.

  13. Nutritional Aspects of Dysphagia Management.

    Science.gov (United States)

    Gallegos, C; Brito-de la Fuente, E; Clavé, P; Costa, A; Assegehegn, G

    This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva. © 2017 Elsevier Inc.

For this reason, in this paper, we tried to highlight the main differences between the trust regulated in the Romanian Civil code and its corespondent in other legal systems. Observing that the trust in an institution that is mainly theoretical, and the reluctance of practicioners in using it, we tried to analyze the trust, regarding its practical side. In this paper, we will take into consideration the following aspects: the rights that the trustee acquires after establishing the trust, that will be explained through the new regulations regarding the division of assets, the quality of the parties and the limits in which the trustee may be held liable. Other important aspects are: the means that the new regulations provide in order to protect the interests of the creditors and at the same time, the fiduciary assets; the formalities which the law requires and the means of termination of the contract. In the end, in order to identify alternative solutions, we will compare the trust (regulated in the Civil code with the management of assets that belong to a third party.

    Nuclear medicine uses radioactive isotopes for diagnostic or therapeutic purposes. The radiation protection culture is now well-anchored in the training of nuclear medicine specialists in France and must remain at the highest possible level. However, practices change and the immediate medical - or even media - interest in new equipment and new tracers must not obscure the fundamentals of patient radiation protection. Particular vigilance is today required with regard to two aspects: - children; - the corresponding computed tomography. (author)

    It is intended in this report to show that it is possible to design an apparatus for measuring the reactivity of a sub-critical nuclear reactor, using a spectral analysis of the variations in the output signal of a counter. The method proposed consists in the measurement of the spectral density in two frequency bands, and in the determination of the 'uncorrelated' components so as to obtain the 'correlated' components, the ratio of these two correlated components giving the reactivity if {beta}/l is known. It is concluded that this method could be applied with the help of a simple apparatus having a measurement range of up to -5000 pcm. Since the efficiency of the detector cannot be increased above a certain value, the accuracy depends largely on the time of measurement: it is shown that it is possible to measure -3000 pcm with an accuracy of {+-} 5 per cent for a time of measurement of 600 seconds. (author) [French] On propose, dans ce travail, de montrer qu'il est possible de realiser un appareil de mesure de la reactivite d'un reacteur nucleaire en regime sous-critique, a partir de l'analyse spectrale des fluctuations du signal de sortie d'un compteur. La methode proposee consiste a mesurer la densite spectrale dans deux bandes de frequences, et a determiner les composantes 'non correlees' de facon a obtenir les composantes 'correlees', le rapport de ces deux composantes correlees permet d'obtenir la reactivite lorsque l'on connait {beta}/l.On en conclut que cette methode peut conduire a la realisation d'un appareil simple, dont la gamme de mesure s'etend jusqu'a - 5 000 pcm. Puisque l'efficacite du detecteur ne peut etre augmentee au-dela d'une certaine valeur, la precision depend, pour une grande part, du temps de mesure: on montre que l'on peut mesurer -3000 pcm avec une precision de {+-} 5 pour cent pour une duree de la mesure de 600 secondes.

    Patel, Neepa; Jankovic, Joseph; Hallett, Mark

    2016-01-01

    Movement disorders, which include disorders such as Parkinson’s disease, dystonia, Tourette’s syndrome, restless legs syndrome, and akathisia, have traditionally been considered to be disorders of impaired motor control resulting predominantly from dysfunction of the basal ganglia. This notion has been revised largely because of increasing recognition of associated behavioural, psychiatric, autonomic, and other non-motor symptoms. The sensory aspects of movement disorders include intrinsic sensory abnormalities and the effects of external sensory input on the underlying motor abnormality. The basal ganglia, cerebellum, thalamus, and their connections, coupled with altered sensory input, seem to play a key part in abnormal sensorimotor integration. However, more investigation into the phenomenology and physiological basis of sensory abnormalities, and about the role of the basal ganglia, cerebellum, and related structures in somatosensory processing, and its effect on motor control, is needed.

  20. Immune Aspects of Female Infertility

    Directory of Open Access Journals (Sweden)

    Andrea Brazdova

    2016-05-01

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

  1. Biomechanical aspects of playing surfaces.

    Science.gov (United States)

    Nigg, B M; Yeadon, M R

    1987-01-01

    The purpose of this paper is to discuss some biomechanical aspects of playing surfaces with special focus on (a) surface induced injuries, (b) methodologies used to assess surfaces and (c) findings from various sports. The paper concentrates primarily on questions related to load on the athlete's body. Data from epidemiological studies suggest strongly that the surface is an important factor in the aetiology of injuries. Injury frequencies are reported to be significantly different for different surfaces in several sports. The methodologies used to assess surfaces with respect to load or performance include material tests and tests using experimental subjects. There is only little correlation between the results of these two approaches. Material tests used in many standardized test procedures are not validated which suggests that one should exercise restraint in the interpretation of these results. Point elastic surfaces are widely studied while area elastic surfaces have received little attention to date. Questions of energy losses on sport surfaces have rarely been studied scientifically.

Under this, the methods for determining the surface structure (such as low energy electron diffraction, field electron and field ion microscopy, photo emission spectroscopy and atomic scattering) and methods for determining the surface composition by the Auger electron spectroscopy are outlined. In the second part, emphasis is on the electronic structure of the clean and adsorbed surfaces. The measurements of ultra-violet and X-ray photo electron spectra are shown to yield the information about the surface electronic structure. In this context the many body effects such as, shake-up and relaxation energy etc. are discussed. Finally the status of the theory in relation to the experiments on angular resolved and polarization dependent photo emission are presented. (auth.)

    1978-09-01

    This U.S. contribution to the syllabus for Subgroup 5C treats with environmental and ecological aspects specific to fast breeder reactors, physical protection and safeguarding of the FBR cycle, fuel cycle centers (site selection problems for different degrees of collocation) and administrative and legal problems. Decommissioning of an FBR power plant, syllabus item C.1.7, is treated in separate contribution, more information on advanced safeguards for the fast breeder fyel cycle is contained in the contribution, USA WG 5C-tbd. A key conclusion of this is that with safeguards planning initiated early in the development of the FBR fuel cycle, time is available to develop, evaluate, and implement improved safeguards techniques and incorporate them into the design phase of all FBR cycle facilities

    Medieval Greek had three future periphrases making use of a finite verb and an infinitive: μέλλω + INF, ἔχω + INF, θέλω + INF. Given the parallel nature of the periphrases as well as the fact that the infinitive existed in both a perfective and an imperfective version, it might be expected...... of the Modern Greek verbal system: μέλλω + INF has a much higher ratio of imperfective infinitives than the two other periphrases especially in AD I, ἔχω + INF starts out using only the perfective infinitive when referring to the future, and θέλω + INF distinguishes for aspect before it gains future meaning...

  5. Legal aspects of nuclear energy

    International Nuclear Information System (INIS)

    Kraut, A.

    1981-01-01

    The legal basis for the use of nuclear energy is generally given by an Atomic Energy Act. Additionally, however, a system of regulations and standards has to be set up to lay down more detailed requirements. The fundamental philosophy and strategy has to be specified by governmental organizations. For the specification and implementation of the requirements some minimum organizational arrangements are necessary, which are not only restricted to governmental organizations. Furthermore procedural regulations have to be laid down before the implementation phase. This includes aspects like public participation in the licensing procedure. In practice, however, the implementation of the legal requirements always shows some weakness of the basic legal requirements. To learn from this experience some examples are presented, which gave rise to difficulties in the implementation procedure. (orig./RW)

    Bricker, O.P.

    1984-01-01

    The general pattern of rain falling on the earth and reacting with the materials of the lithosphere (the weathering reactions so familiar to every beginning geology student) began soon after the earth was formed and has continued to the present. Anthropogenic additions to the natural acidic components of the atmosphere have increased since the time of the industrial revolution until they now rival or exceed those of the natural system. The severity of the environmental perturbations caused by these anthropogenic additions to the atmosphere has become a hotly debated topic in scientific forums and in the political arena. The six chapters in this book address various aspects of the acid deposition phenomenon from a geological perspective. It is hoped that the geological approach will be useful in bringing the problem more clearly into focus and may shed light on the geochemical processes that modify the chemical composition of acid deposition after it encounters and reacts with the materials of the lithosphere

  8. Psychological aspects of cancer patients

    2014-06-01

    Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.

    2005-04-01

    Molecular aspects of Down syndrome (DS), a major genetic cause for mental retardation, commonly associated with trisomy 21 are discussed. Two different hypotheses have been speculated to better understand the disease. One believes that increased gene dosage contributes to the phenotypic abnormalities; the other correlates genetic imbalance with DS pathogenesis. To sustain these hypotheses, different murine models have been developed. Experimental models as well as sequencing of human chromosome 21 helped in speculating a few possible candidate genes for DS. However, the phenotypic changes involved with this neurological disorder vis-a-vis the enhanced number of genes, still remain unexplained. Improvement in screening pattern, model system, as well as better understanding of the disease etiology may help in developing efficacious therapeutic regimes for DS.

    1982-02-01

    The purpose of this paper is to present a brief description of fuel reprocessing and some present developments which show the reliability of nuclear energy as a long-term supply. The following topics are discussed: technical reasons for reprocessing; economic reasons for reprocessing; past experience; justification for advanced reprocessing R and D; technical aspects of current reprocessing development. The present developments are mainly directed at the reprocessing of breeder reactor fuels but there are also many applications to light-water reactor fuel reprocessing. These new developments involve totally remote operation, and maintenance. To demonstrate this advanced reprocessing concept, pilot-scale demonstration facilities are planned with commercial application occurring sometime after the year 2000

    The authors highlight a few medical, biological and psycological aspects of the use of nuclear weapons, drawing attention to their viewpoint that doctors should actively participate in the fight against nuclear armament. The short and long-term radiation effects on man and ecology are presented based on the Hiroshima and Nagasaki experiences. The danger of human error within this framework is emphasised and it is suggested that it is the medical profession's duty to point out how the effect of stress and boredom can lead to a nuclear catastrophe. Medical expertise may also help in the identification of unstable personalities among those who have access to nuclear weapons and in the understanding of the psycology of international conflicts and the psychopathology of those leaders who would use nuclear war as an instrument of national policy. Finally the effects of the nuclear war threat on children and teenagers are considered. (C.F.)

    International Nuclear Information System (INIS)

    Thumim, A.D.

    1975-01-01

    A scintillation counter, particularly for counting gamma ray photons, includes a massive lead radiation shield surrounding a sample-receiving zone. The shield is disassembleable into a plurality of segments to allow facile installation and removal of a photomultiplier tube assembly, the segments being so constructed as to prevent straight-line access of external radiation through the shield into radiation-responsive areas. Provisions are made for accurately aligning the photomultiplier tube with respect to one or more sample-transmitting bores extending through the shield to the sample receiving zone. A sample elevator, used in transporting samples into the zone, is designed to provide a maximum gamma-receiving aspect to maximize the gamma detecting efficiency. (U.S.)

    2013-01-01

    Full Text Available We raise several elementary questions pertaining to various aspects of means. These questions refer to both known and newly introduced families of means, and include questions of characterizations of certain families, relations among certain families, comparability among the members of certain families, and concordance of certain sequences of means. They also include questions about internality tests for certain mean-looking functions and about certain triangle centers viewed as means of the vertices. The questions are accessible to people with no background in means, and it is also expected that these people can seriously investigate, and contribute to the solutions of, these problems. The solutions are expected to require no more than simple tools from analysis, algebra, functional equations, and geometry.

    Full Text Available Melanomas are malignant neoplasms originating from melanocytes. They occur in most animal species, but the dog is considered the best animal model for the disease. Melanomas in dogs are most frequently found in the buccal cavity, but the skin, eyes, and digits are other common locations for these neoplasms. The aim of this review is to report etiological, epidemiological, pathological, and molecular aspects of melanomas in dogs. Furthermore, the particular biological behaviors of these tumors in the different body locations are shown. Insights into the therapeutic approaches are described. Surgery, chemotherapy, radiotherapy, immunotherapy, and the outcomes after these treatments are presented. New therapeutic perspectives are also depicted. All efforts are geared toward better characterization and control of malignant melanomas in dogs, for the benefit of these companion animals, and also in an attempt to benefit the treatment of human melanomas.

  15. Holistic aspects of quantum mechanics

    International Nuclear Information System (INIS)

    Pietschmann, H.

    1987-01-01

    Aspects of quantum mechanics irreconcilable with classical physics are outlined. Quantum mechanics started with a negative statement about reality, namely: it is impossible to determine momentum and position of a particle simultaneously. Meanwhile it has generated an impressive body of predictions which can be tested and have been confirmed by suitable experiments. As a consequence a naive, local, materialistic concept of reality must be abolished and a novel approach, the holistic is introduced. This is illustrated by some examples e.g. the Pauli exclusion principle for electrons, the electron capture decay of 135 La as a model of the wavefunction reduction, the Bohr radius of the atom, electron localisation in the atom. An example from the quantum field theory is the calculation of magnetic moments of electron and muon where a particle cannot be considered separately and all other particles must be taken into account.

    Full Text Available The slipper lobster, Scyllarides latus (Latreille, 1803, is the only representative species of the genusScyllarides in the Mediterranean Sea. In this study, we examined some biological aspects of this species sampled in the Straits of Messina. The specimens were sexed, measured and weighed. The relationships between body measurements (length and width of the carapace, antennal length and length-weight relationship were calculated. Furthermore, the correlation matrix (Pearson’s coefficient was calculated. Two hundred specimens were collected, ranging in size from 81 to 305 mm in total length, and between 21 and 1490 g in weight. A rare juvenile of 39 mm CL was recorded. A sex ratio of 1:1 was found. The carapace length – weight relationship was almost isometric. The wide size range sampled and the presence of a juvenile, indicate an interesting habitat for studying the presence and growth of Scyllarides latus in the Straits of Messina.

    The paper presents the aspects of international GHG (greenhouse gases) emission trading, such as: quality of GHG emission data, possible partners, monitoring activity, market mechanisms and difficulties. The following conclusions are drown: - debates on international trade with GHG emissions are currently in a very early stage; - actions are possible and feasible, particularly after Kyoto Conference, as versatile mechanism (besides the Joint Implementation Projects) which have in view the lowering of the global emission costs in different zones of the planet; - difficulties concerning monitoring, reporting and verification, practically preclude implementing a system of emission trading covering all the GHG, all the sources and reservoirs; - an international viable system of emission trading could initiate with a limited number of participants and consideration of only emission categories easy to be confined and surveyed; - existence of a national market and corresponding institutions for monitoring which could booster an international system development

    In this paper there are showed and debated some situation in which psychological effects like loss aversion, reference point, status-quo and framming effects can influence the deccision of the consumer and are not consistent with the standard economic model.In addition to this aspects, Cumulative Prspect Theory enhance the fact that decision makers overestimate low peobabilities and underestimate high probabilities,thus buying inadequate insurance in many situation.in thiss sense, in order to support this idea I tried to make a qualitative presentation of the model used on the insurance market using Prelec function which is the function related with the Cumulative Prospect Theory which can be used in the insurance context.The weak points of the theory of expected utility are explained through this new perspectives and nevertheless aspects like insensivity to bad news concerning incomes,elasticity of price,displacements of status-quo and default,disposition effect and equity premium are taken into consideration.As example,I chose a Kunreuther experiment about insurance decision in with is underlyined the fact that for moderate risk people buy insurance with premiums that exceed the expected loss.There are demands for low deductibles in the the markets for extended guarantees and insurances for mobile phones where was observed that the insurance underwriting rate increases with the probability of loss keeping the expected loss constant.It is better to mention that the theory and the model that are presented here comes as complementary to the economic standard theory not as a substitute.

    After a presentation of the tritium sources in our environment, is evoked succinctly the different ways to produce it. Then, for each reactor type, are presented the main problematics due to tritium. In this part, the questions of tritium transfer are illustrated for fission reactors: pressurized water reactors, CANDU reactors and for fast neutrons reactors. The case of fusion tokamaks is described more particularly. Several aspects are presented successively: the requirement to produce it in-situ with fitted materials, the definition of a short fuel cycle allowing to recover important quantities of tritium having not react...In a last part, are presented the aspects directly induced by the behaviour of tritium in materials. The first point concerned is the control of the tritium inventory in a fusion tokamak, for safety reasons. Examples are given from experiment feedback on running fusion tokamaks. A projection at the ITER case is proposed. The mechanisms leading to tritium retention according to the materials considered at the present time are analyzed and synthesized. The second important point is the tritium management at the end of the tokamak running. The specific problematics of this management are presented. (O.M.)

    2012-01-01

    Fibromyalgia (FM) is a clinical syndrome commonly observed in daily medical practice and its etiopathogenesis is still unclear. As it is characterized by chronic musculoskeletal pain associated with several symptoms, FM may be confused with several other rheumatic and nonrheumatic diseases when they course with pictures of diffuse pain and chronic fatigue. FM treatment should be multidisciplinary, individualized, count on active participation of the patient, and based on combined pharmacological and nonpharmacological modalities. It is found both in work and non-work settings, and there is no scientific evidence in the literature showing that FM might be caused by occupation. FM seldom leads to incapacity to work. In cases where pain or fatigue do not respond to appropriate treatment, reaching significant levels, a short period away from work can be considered. As FM is a relevant subject, this review article was based on exploratory, qualitative, and bibliographic investigation, aiming to study the main clinical and occupational aspects of FM, emphasizing the theoretical-conceptual background and the experience of specialists.

  4. Geotechnical Aspects of Explosive Compaction

    2016-01-01

    Full Text Available Explosive Compaction (EC is the ground modification technique whereby the energy released from setting off explosives in subsoil inducing artificial earthquake effects, which compact the soil layers. The efficiency of EC predominantly depends on the soil profile, grain size distribution, initial status, and the intensity of energy applied to the soil. In this paper, in order to investigate the geotechnical aspects, which play an important role in performance of EC, a database has been compiled from thirteen-field tests or construction sites around the world, where EC has been successfully applied for modifying soil. This research focuses on evaluation of grain size distribution and initial stability status of deposits besides changes of soil penetration resistance due to EC. Results indicated suitable EC performance for unstable and liquefiable deposits having particle sizes ranging from gravel to silty sand with less than 40% silt content and less than 10% clay content. However, EC is most effective in fine-to-medium sands with a fine content less than 5% and hydraulically deposited with initial relative density ranging from 30% to 60%. Moreover, it has been observed that EC can be an effective method to improve the density, stability, and resistance of the target soils.

    2017-01-01

    Full Text Available Psychopathy is characterised by emotional disturbances that affect interpersonal behaviour and decision-making. The objective of this paper is to review the most recent contributions to the field of neuroscience of psychopathy and the implications that this disorder has on the criminal legal field. In regards to this last aspect, we evaluate the issue of psychopaths’ accountability and the incidence of psychopathy in many other penal institutions. In terms of the contributions of neuroscience, we will focus on the orbitofrontal (ofPFC and ventromedial (vmPFC regions of the frontal lobes and on the amygdala. Data spanning from the nineteenth century to the present indicate that damage to the ofPFC and vmPFC is the basis of behaviours that have been referred to as pseudopsychopathic. The earlier during brain development the damage occurs, the more likely these behaviours will resemble those of psychopaths. The damage to the amygdala is rather related to impairments in the ability to distinguish facial expressions of fear and the capacity to feel emotions. Damage to ofPFC, vmPFC, and amygdala are highly relevant to the expression of pseudopsychopathic behaviours.

    1989-11-01

    Data available in the literature on the nutritional aspects of irradiated shrimp are reviewed and the indication is that irradiation of shrimp at doses up to about 3.2 kGy does not significantly affect the levels of its protein, fat, carbohydrate and ash. There are no reports on the effect of irradiation of shrimp above 3.2 kGy on these components. Limited information available indicates that there are some minor changes in the fatty acid composition of shrimp as a result of irradiation. Irradiation also causes some changes in the amino acid composition of shrimp; similar changes occur due to canning and hot-air drying. Some of the vitamins in shrimp, such as thiamine, are lost as a result of irradiation but the loss is less extensive than in thermally processed shrimp. Protein quality of shrimp, based on the growth of rats as well as that of Tetrahymena pyriformis, is not affected by irradiation. No adverse effects attributed to irradiation were found either in short-term or long-term animal feeding tests

    Background: tumors arising from sacrococcygeal region are weird and represent from one to seven percent of primary spinal tumors. However diagnosis and treatment are a challenge for the surgical staff because of the anatomic relations complexity and the more frequent lesions biological features. Objective: a review of the literature was done to update and systematize the knowledge about general aspects of sacrococcygeal tumors. Development: they are more frequent in male young adults, unspecific low back pain is the onset symptom and muscle weakness, sense deficit and sphincter disturbances join up later progressively. They can be epidural or intradural, primary or secondary, neoplastics or not and they could arise from soft tissues or bone structure. Age and location most be considered to evaluate malignant potential. CT scan and magnetic resonance imaging are the confirmatory tests and allow surgical approach selection. The most frequent affections are chordoma, aneurismal bone cyst and giant cell tumor. Radiotherapy and chemotherapy can support surgery according to histology. Conclusions: precocious diagnosis needs to be suspected before unspecific symptoms. Sacrococcygeal tumors treatment most be multidisciplinary and multimodal to assure better prognosis and patient´s life expectancy increasing. (author)

  8. Biophysical Aspects of Transmembrane Signaling

    CERN Document Server

    Damjanovich, Sandor

    2005-01-01

    Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world. This book handles both aspects of the signalling events, and in some cases tries to unify our concepts and help understand the signals that govern the life and death of our cells. Not only the understanding, bu...

    2003-01-01

    Compact stellarators could combine the good confinement and high beta of a tokamak with the inherently steady state, disruption-free characteristics of a stellarator. Two U.S. compact stellarator facilities are now in the conceptual design phase: the National Compact Stellarator Experiment (NCSX) and the Quasi- Poloidal Stellarator (QPS). NCSX has a major radius of 1.4 m and a toroidal field up to 2 T. The primary feature of both NCSX and QPS is the set of modular coils that provide the basic magnetic configuration. These coils represent a major engineering challenge due to the complex shape, precise geometric accuracy, and high current density of the windings. The winding geometry is too complex for conventional hollow copper conductor construction. Instead, the modular coils will be wound with flexible, multi strand cable conductor that has been compacted to a 75% copper packing fraction. Inside the NCSX coil set and surrounding the plasma is a highly contoured vacuum vessel. The vessel consists of three identical, 120 deg. segments that are bolted together at double sealed joints. The QPS device has a major radius of 0.9 m, a toroidal field of 1 T, and an aspect ratio of only 2.7. Instead of an internal vacuum vessel, the QPS modular coils will operate in an external vacuum tank. (author)

    Analysis of existing aspects of bacteriophage use and study features of their lytic activity by using various techniques. Effect of monophages and associated bacteriophages (staphylococci, piopolyvalent and piocombined, intestiphage, pneumonia klebsiella and polyvalent klebsiella produced by "Microgen") was studied with 380 strains of Staphylococcus aureus and 279 cultures of Klebsiella pneumoniae in liquid and solid nutrient media. From patients with intestinal disorder, sensitivity was analyzed to 184 strains of Salmonella genus bacteria 18 serological variants to salmonella bacteriophages, 137 strains of Escherichia coli (lactose-negative, hemolytic), as well as some members of OKA groups (21 serovars) to coli-proteic and piopolyvalent bacteriophages. Lytic ability of the piobacteriophage against Klebsiella and Proteus genus bacteria was determined. Staphylococcus aureus was sensitive to staphylococcus bacteriophage in 71.6% of cases and to piobacteriophage--in 86.15% of cases. A 100% lytic ability of salmonella bacteriophage against Salmonella spp. was established. Sensitivity of E. coli of various serogroups to coli-proteic and piobacteriophage was 66 - 100%. Klebsiella, Proteus genus bacteria were sensitive to piobacteriophage in only 35% and 43.15% of cases, respectively. A more rational use of bacteriophages is necessary: development of a technique, evaluation of sensitivity of bacteria to bacteriophage, introduction of corrections into their production (expansion of bacteriophage spectra, determination and indication of their concentration in accompanying documents).

    2006-01-01

    Over the last three decades photodynamic therapy (PDT) has been developed to a useful clinical tool, a viable alternative in the treatment of cancer and other diseases. Several disciplines have contributed to this development: chemistry in the development of new photosensitizing agents, biology in the elucidation of cellular processes involved in PDT, pharmacology and physiology in identifying the mechanisms of distribution of photosensitizers in an organism, and, last but not least, physics in the development of better light sources, dosimetric concepts and construction of imaging devices, optical sensors and spectroscopic methods for determining sensitizer concentrations in different tissues. Physics and biophysics have also helped to focus on the role of pH for sensitizer accumulation, dose rate effects, oxygen depletion, temperature, and optical penetration of light of different wavelengths into various types of tissue. These are all important parameters for optimally effective PDT. The present review will give a brief, physically based, overview of PDT and then discuss some of the main biophysical aspects of this therapeutic modality.

  14. Aspects of differential geometry II

    CERN Document Server

    Gilkey, Peter

    2015-01-01

    Differential Geometry is a wide field. We have chosen to concentrate upon certain aspects that are appropriate for an introduction to the subject; we have not attempted an encyclopedic treatment. Book II deals with more advanced material than Book I and is aimed at the graduate level. Chapter 4 deals with additional topics in Riemannian geometry. Properties of real analytic curves given by a single ODE and of surfaces given by a pair of ODEs are studied, and the volume of geodesic balls is treated. An introduction to both holomorphic and Kähler geometry is given. In Chapter 5, the basic properties of de Rham cohomology are discussed, the Hodge Decomposition Theorem, Poincaré duality, and the Künneth formula are proved, and a brief introduction to the theory of characteristic classes is given. In Chapter 6, Lie groups and Lie algebras are dealt with. The exponential map, the classical groups, and geodesics in the context of a bi-invariant metric are discussed. The de Rham cohomology of compact Lie groups an...

    Full Text Available Peacekeeping operations are but one aspect of the systems of peace that have evolved over the past seven decades in a world that is riven with violence of all kinds. With the end of cold war in the late eighties of the last century we have come to see much intrastate violence, in addition to usual interstate hostilities and war, arising out of religious, political, ethnic and economic differences between people. In the changed scenario peacekeeping operations have become complex politico-military-humanitarian efforts. A soldier, trained for conventional military operations, is obliged to participate in the unconventional operations of waging peace in alien lands often in volatile and violent situations and in the process he stands to get exposed to widely variable demands for adjustment that have the potential to bring to the fore many maladaptive responses. Peacekeeping operations also have the potential to offer opportunities for growth and resilience. India is a major player in peacekeeping activities for well over sixty years all over the world. It is necessary for the commanders and mental health professionals to understand the multifarious factors that impinge on the peacekeeping soldier′s mind and the emerging patterns of responses thereof for effective management trained manpower and fulfillment of mission objectives

  16. Technical aspects of MR perfusion

    Sourbron, Steven

    2010-01-01

    The most common methods for measuring perfusion with MRI are arterial spin labelling (ASL), dynamic susceptibility contrast (DSC-MRI), and T 1 -weighted dynamic contrast enhancement (DCE-MRI). This review focuses on the latter approach, which is by far the most common in the body and produces measures of capillary permeability as well. The aim is to present a concise but complete overview of the technical issues involved in DCE-MRI data acquisition and analysis. For details the reader is referred to the references. The presentation of the topic is essentially generic and focuses on technical aspects that are common to all DCE-MRI measurements. For organ-specific problems and illustrations, we refer to the other papers in this issue. In Section 1 'Theory' the basic quantities are defined, and the physical mechanisms are presented that provide a relation between the hemodynamic parameters and the DCE-MRI signal. Section 2 'Data acquisition' discusses the issues involved in the design of an optimal measurement protocol. Section 3 'Data analysis' summarizes the steps that need to be taken to determine the hemodynamic parameters from the measured data.

    Crowns, fixed partial dentures, and removable dentures are the popular prosthetic dental restorations in current dental practice. Prosthodontic rehabilitation of the mouth, particularly in advanced and complex cases, requires careful planning, adequate clinical skills, and exacting technical standards. While a successful outcome is the ultimate goal for any prosthodontic treatment, complications, injuries, dissatisfaction, and/or failure may occur. When such events develop as a result of negligence or violation of standards of care, they are considered under the term of malpractice and may incur ethical and medico-legal implications. This paper reviews and highlights some aspects of malpractice in prosthodontics. The current state of prosthodontic malpractice on a global level will also be evaluated. Standards of prosthodontic care, current literature of prosthodontic malpractice, where and how prosthodontic malpractice occurs, and recommendations for the future are presented. A thorough understanding of what is quality prosthodontic care and what disrupts this care can be a useful guard against professional litigation and may protect patients from poor quality of dental prosthetic care. © 2017 by the American College of Prosthodontists.

    Ho, P.M.

    1996-01-01

    Various geometrical aspects of quantum spaces are presented showing the possibility of building physics on quantum spaces. In the first chapter the authors give the motivations for studying noncommutative geometry and also review the definition of a Hopf algebra and some general features of the differential geometry on quantum groups and quantum planes. In Chapter 2 and Chapter 3 the noncommutative version of differential calculus, integration and complex structure are established for the quantum sphere S 1 2 and the quantum complex projective space CP q (N), on which there are quantum group symmetries that are represented nonlinearly, and are respected by all the aforementioned structures. The braiding of S q 2 and CP q (N) is also described. In Chapter 4 the quantum projective geometry over the quantum projective space CP q (N) is developed. Collinearity conditions, coplanarity conditions, intersections and anharmonic ratios is described. In Chapter 5 an algebraic formulation of Reimannian geometry on quantum spaces is presented where Riemannian metric, distance, Laplacian, connection, and curvature have their quantum counterparts. This attempt is also extended to complex manifolds. Examples include the quantum sphere, the complex quantum projective space and the two-sheeted space. The quantum group of general coordinate transformations on some quantum spaces is also given

    1988-01-01

    Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a ''clean fuel,'' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process

    The theoretical aspects of thermonuclear fusion induced by laser are discussed. After outlining the basic features and the energetics of laser fusion in the chapter 1, various non-linear mechanisms responsible for an enhanced absorption of laser energy into the plasma and the stimulated scattering processes which hinder the absorption are discussed in the second chapter on laser plasma interactions. The third chapter on gas dynamics and the shock phenomena presents the mathematical formulation of the compression to high densities of the core of the pellet for its implosion. A hydrodynamic model developed to stimulate the evolution of laser heated symmetric plasma is outlined in the chapter four on numerichigly relativistic noninteracting particles, regular bouncing states may occur at high densities, or at high temperatures. The latter case is considered in details for the collapse phase of a hot universe; lepton pair creation may completely decelerate the collapse of a hot hadronic plasma, provided the observational parameters, the Hubble constant Hsub(deg), the matter parameter Ωsub(deg) and the deceleration parameter qsub(deg) satisfy certain constraint conditions

    For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

  3. Aspects of the Tutte polynomial

    DEFF Research Database (Denmark)

    Ok, Seongmin

    This thesis studies various aspects of the Tutte polynomial, especially focusing on the Merino-Welsh conjecture. We write T(G;x,y) for the Tutte polynomial of a graph G with variables x and y. In 1999, Merino and Welsh conjectured that if G is a loopless 2-connected graph, then T(G;1,1) ≤ max{T(G;2......,0), T(G;0,2)}. The three numbers, T(G;1,1), T(G;2,0) and T(G;0,2) are respectively the numbers of spanning trees, acyclic orientations and totally cyclic orientations of G. First, I extend Negami's splitting formula to the multivariate Tutte polynomial. Using the splitting formula, Thomassen and I found......-Welsh conjecture has a stronger version claiming that the Tutte polynomial is convex on the line segment between (2,0) and (0,2) for loopless 2-connected graphs. Chavez-Lomeli et al. proved that this holds for coloopless paving matroids, and I provide a shorter proof of their theorem. I also prove it for minimally...

    Full Text Available The historical data on the development of medicine as a science, with an emphasis on aspects of the endocrinology, are given in this paper. The role of Ukrainian and foreign scientists and their contribution to the development of the chemistry of hormones has been clarified in a historical context. The role of schools, academies in shaping the outlook of future scientists and the promotion of best practices is shown. The article shows how the knowledge of medicine was gradually accumulated: clinical manifestations, definition of laboratory differences. The ability to provide pathogenetic treatment to the patient with endocrine disease was possible in most cases only after the industrial synthesis of hormones. The works of many scientists were awarded the Nobel Prize in medicine and physiology. The definition of “hormone”, classification, place of biosynthesis, particularly of the secretion, the industrial synthesis of some of them and the scope of use are presented. Special attention is paid to the description of new methods of synthesis of thyroxine, flutapharm and other substances.

    Physical aspects of medical science involve making physical models, physical approaches, and measurements by physical instruments. Among these, the physical approach is the most important for an exact elucidation of the physiological function of living materials. What is a physical approach? In the first step, the molecular mechanism of visual transduction will be demonstrated by considering the physical characteristics of diffusion of second messengers. In the next step, I will consider how frequency modulation-type impulse signaling is converted from amplitude modulation-type electric signaling. In the last section, I will discuss how impulse signaling (i.e., the train of action potentials) is processed by the neural network in the brain and eventually is recognized in the frontal cortex using near infrared spectroscopy. In order to obtain such a physical model of vision, many physical concepts are used, such as light reflex, energy transduction, diffusion of molecules, threshold, the Coulomb interaction, light absorption, and cluster analysis. Among them, the Coulomb interaction, light absorption, and diffusion of molecules are three essential keywords for the physical process. Copyright © 2011. Published by Elsevier B.V.

    2007-03-01

    The notion of 'fluency' is most often associated with spoken-language phenomena such as stuttering. The present article investigates the relevance of considering fluency in writing. The basic argument for raising this question is empirical-it follows from a focus on difficulties in written and spoken language as manifestations of different problems which should be investigated separately on the basis of their symptoms. Key-logging instruments provide new possibilities for the study of writing. The obvious use of this new technology is to study writing as it unfolds in real time, instead of focusing only on aspects of the end product. A more sophisticated application is to exploit the key-logging instrument in order to test basic assumptions of contemporary theories of spelling. The present study is a dictation task involving words and non-words, intended to investigate spelling in nine-year-old pupils with regard to their mastery of the doubling of consonants in Norwegian. In this study, we report on differences with regard to temporal measures between a group of strong writers and a group of poor ones. On the basis of these pupils' writing behavior, the relevance of the concept of 'fluency' in writing is highlighted. The interpretation of the results questions basic assumptions of the cognitive hypothesis about spelling; the article concludes by hypothesizing a different conception of spelling.

    In the steam explosion research field there is currently considerable effort being devoted to the modelling of premixing. Practically all models are based on the multiphase flow equations which treat the mixture as an interpenetrating continuum. Solution of these equations is non-trivial and a wide range of solution procedures are in use. This paper addresses some numerical aspects of this problem. In particular, we examine the effect of the differencing scheme for the convective terms and show that use of hybrid differencing can cause qualitatively wrong solutions in some situations. Calculations are performed for the Oxford tests, the BNL tests, a MAGICO test and to investigate various sensitivities of the solution. In addition, we show that use of a staggered grid can result in a significant error which leads to poor predictions of `melt` front motion. A correction is given which leads to excellent convergence to the analytic solution. Finally, we discuss the issues facing premixing model developers and highlight the fact that model validation is hampered more by the complexity of the process than by numerical issues. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Barriere, N

    2008-04-15

    The Laue lenses we study focuses in the domain of 0.1-1 MeV thanks to Bragg diffraction in the volume of a large number of small crystal tiles. The focal length of a typical Laue lens system is of the order of 100 m. This requirement calls for two formation flying satellites maintaining lens and detector at the focal distance. The major breakthrough of Laue lenses is to decouple collecting area from detector area. Concentrating a signal from the large area of a Laue lens onto a small focal spot dramatically increases the signal over background ratio with respect to present technologies. Here is the reason for the long awaited leap in sensitivity. The objective of the present thesis was to improve the concept, finding viable technical solutions towards a future space mission. Two aspects of the lens development have been highlighted in this thesis: the first one is an analytical model of the lens that is used to calculate and improve the performance of a certain configuration, the second aspect concerns the search and the characterization of diffracting media of interest. The lens model developed relies on a fast semi-analytical simulation library, permitting to build several design- and optimisation-tools. For the configuration of a given lens, this code computes the resulting effective area and point spread function in a handful of seconds. The model helps finding lens configurations (mass, pack ratio of the lens rings,...) which are automatically refined to match with effective area and energy coverage constraints. These tools have been used to investigate various design aspects, such as the influence of focal length, size, mosaic spread, structure and materials of crystals, etc... The central evaluation criterion in the model is a figure of merit, based on the compactness of the focal spot and the intensity of the collected signal. The second part of this work addresses the actual search and characterization of crystals potentially interesting for Laue lenses

  14. Electrical Aspects of Impinging Flames

    Science.gov (United States)

    Chien, Yu-Chien

    This dissertation examines the use of electric fields as one mechanism for controlling combustion as flames are partially extinguished when impinging on nearby surfaces. Electrical aspects of flames, specifically, the production of chemi-ions in hydrocarbon flames and the use of convective flows driven by these ions, have been investigated in a wide range of applications in prior work but despite this fairly comprehensive effort to study electrical aspects of combustion, relatively little research has focused on electrical phenomena near flame extinguishment, nor for flames near impingement surfaces. Electrical impinging flames have complex properties under global influences of ion-driven winds and flow field disturbances from the impingement surface. Challenges of measurements when an electric field is applied in the system have limited an understanding of changes to the flame behavior and species concentrations caused by the field. This research initially characterizes the ability of high voltage power supplies to respond on sufficiently short time scales to permit real time electrical flame actuation. The study then characterizes the influence of an electric field on the impinging flame shape, ion current and flow field of the thermal plume associated with the flame. The more significant further examinations can be separated into two parts: 1) the potential for using electric fields to control the release of carbon monoxide (CO) from surface-impinging flames, and 2) an investigation of controlling electrically the heat transfer to a plate on which the flame impinges. Carbon monoxide (CO) results from the incomplete oxidation of hydrocarbon fuels and, while CO can be desirable in some syngas processes, it is usually a dangerous emission from forest fires, gas heaters, gas stoves, or furnaces where insufficient oxygen in the core reaction does not fully oxidize the fuel to carbon dioxide and water.

    One of the modern economy models is circular economy in which wastes should be considered as resource and used in an efficient and sustainable way. This also concerns to metals included in scraps. However, the need for metal recovery from waste is not only the result of the latest economic trends but also the result of large and constantly changing demand for metals. Shrinking natural sources of metals, concentrations of ores in small number of countries in the world and resulting from this dependence on import, geopolitical situation, new technologies demands are only a few most important determinants that have been changing the structure of the metal market over years. In this chapter, authors focused on the presentation of economic aspects of metal recovery from various sources. The chapter presents the characteristic of metal market elements (supply, demand and price) and changes that took place over decades, underlining the structure of precious and highly desirable metal market elements. Balance between the demand and supply ensures price stability and rationalizes inflation. However, growing demand on many means that secure supply chains, such as recycling and material recovery, are essential to ensure continuity in the supply chain and guarantee unrestricted technological progress and innovation. The data included in this chapter presents also the concentration of different metals and group of metals in wastes pointing that recycling of waste can become one of the possibilities of acquiring missing and critical metals. Metal-laden wastes include a few groups: waste electrical and electronic equipments, catalysts of different application, introduced on chemical, petrochemical or automotive market, galvanic wastes and wastewaters. The profitability assessment of recycling processes is very complicated. Nevertheless cited data shows that profitability of recovery depends on the metal analyzed and the type of waste. It must be underline that an optimized

    1989-09-01

    The accident at Chernobyl revealed that there were shortcomings and gaps in the existing international mechanisms and brought home to governments the need for stronger measures to provide better protection against the risks of severe accidents. The main thrust of international co-operation with regard to nuclear safety issues is aimed at achieving a uniformly high level of safety in nuclear power plants through continuous exchanges of research findings and feedback from reactor operating experience. The second type of problem posed in the event of an accident resulting in radioactive contamination of several countries relates to the obligation to notify details of the circumstances and nature of the accident speedily so that the countries affected can take appropriate protective measures and, if necessary, organize mutual assistance. Giving the public accurate information is also an important aspect of managing an emergency situation arising from a severe accident. Finally, the confusion resulting from the unwarranted variety of protective measures implemented after the Chernobyl accident has highlighted the need for international harmonization of the principles and scientific criteria applicable to the protection of the public in the event of an accident and for a more consistent approach to emergency plans. The international conventions on third party liability in the nuclear energy sector (Paris/Brussels Conventions and the Vienna Convention) provide for compensation for damage caused by nuclear accidents in accordance with the rules and jurisdiction that they lay down. These provisions impose obligations on the operator responsible for an accident, and the State where the nuclear facility is located, towards the victims of damage caused in another country

  17. Chemical aspects of irradiated mangoes

    Singh, H.

    1990-06-01

    Mango is an important and very popular tropical fruit. Because of its short shelf life, however, its use is restricted to the areas of production. Since mango is a climacteric fruit, it is possible to extend its shelf life by delaying the ripening process and senescence by irradiation. The ripening process is very complex: it appears that the radiation-induced delay in ripening may be mediated through the inhibition of the enzyme(s) involved in ethylene production. The dose required for shelf-life extension is ≤1.5 kGy. Higher doses can lead to scalding, flesh darkening and development of hollow pockets. This review focuses on the chemical aspects of radiation-induced shelf-life extension of mangoes. At the low irradiation doses required for this shelf-life extension (≤1.5 kGy), the chemical effects are negligible. Irradiation does not affect the carotenoid levels, and has only a minor effect on the vitamin C level in a few mango varieties. No significant differences in the free and total (hydrolyzed) amino acids, or the protein content of Kent mangoes, have been detected between irradiated and unirradiated samples. During ripening of the mangoes the reducing sugar and the total sugar levels increase, but in the majority of the mango varieties these levels remain very similar in irradiated and unirradiated samples. There are some differences in the volatile compounds between irradiated and unirradiated Kent mangoes; however, these differences have no apparent effect on the taste and flavor of the irradiated mangoes

    Full Text Available The world practice of using agrochemicals for long periods, in an indiscriminated and abusive way, has been a concern of the authorities involved in public health and sustainability of the natural resources, as a consequence of environmental contamination. Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively used in sugarcane, corn and sorghum cultures, among others. Researches have demonstrated that atrazine has toxic effects in algae, aquatic plants, aquatic insects, fishes and mammals. Due to the toxicity and persistence of atrazine in the environment, the search of microbial strains capable of degrading it is fundamental to the development of bioremediation processes, as corrective tools to solve the current problems of the irrational use of agrochemicals. This review relates the main microbial aspects and research on atrazine degradation by isolated microbial species and microbial consortia, as well as approaches on the development of techniques for microbial removal of atrazine in natural environments.A prática mundial do uso de agroquímicos por períodos extensos, de maneira indiscriminada e abusiva, tem mobilizado as autoridades envolvidas em saúde pública e sustentabilidade de fontes naturais, como uma conseqüência da contaminação ambiental. Agroquímicos referem-se a uma ampla variedade de inseticidas, fungicidas e herbicidas, entre estes a atrazina, um herbicida intensivamente usado em culturas de cana-de-açúcar, milho, sorgo, entre outros. Pesquisadores têm demonstrado que a atrazina tem efeitos tóxicos em algas, plantas aquáticas, insetos aquáticos, peixes e mamíferos. Devido à toxicidade e à persistência da atrazina no ambiente, a busca de linhagens microbianas capazes de degradá-la é fundamental para o desenvolvimento de processos de biorremediação, com uma ferramenta corretiva para solucionar problemas decorridos do uso

  19. ETHICAL ASPECTS OF ENVIRONMENTAL MANAGEMENT

    Full Text Available The purpose of this article is to outline the main economical and social benefits that can be obtained by adopting an ethical attitude of the organisations which use a performant environmental management. From the idea that the human being is the master of nature, it was passed to the view according to which the human being must ensure a balance between consumption and the use of resources. In order to achieve our goal we identified the factors that lead to long term or even permanent destructive effects over the environment and we briefly present the reasons for which the organizations adopt and implement environmental management systems. Also, the difficulties encountered in implementing environmental strategies have been briefly enumerated and the competitive and economic advantages that can be achieved by adopting an efficient environmental management and the main reasons that grant to the environmental management a special significance were exposed. This theoretical paper emphasizes the importance of the adoption by organizations of a "green behavior" and reveals correlations between sustainability, economic growth and environmental performance in organizations. The analysis of the ethical aspects of environmental management shows the links that can be created between the development of an ethical culture of organizations and the achievement of the environmental excellence. The research provides an overview of the concept of environmental ethics and encloses it within the scope of environmental management. Someone needs to explain why an increasing number of organizations, both large and small, are setting up environmental management systems, making environmental investments and reducing risks over and beyond legal requirements, even when the benefits are not at all obvious, even in the long run. Also, this paper provides some practical examples of organizations environmental problems and points out how these organizations adapted their

Another important aspect of clinical efficacy of medications in space is the stability of pharmaceuticals. As the U.S. space program is moving toward extended Space Shuttle flights and beyond, to space station missions and planetary explorations, understanding how space flight affects organ systems and clinical pharmacology is necessary to optimize pharmacotherapeutics in space and ensure adequate safety and health of crewmembers.

    radio systems. From the point of view Working Group 2 of the COST 296 Action, interest lies with effects associated

    with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:

    a The directions of arrival and times of flight of signals received over a path oriented along the trough have

    been examined and several types of propagation effects identified. Of particular note, combining the HF observations

    with satellite measurements has identified the presence of irregularities within the floor of the trough that

    result in propagation displaced from the great circle direction. An understanding of the propagation effects that

    result in deviations of the signal path from the great circle direction are of particular relevance to the operation

    of HF radiolocation systems.

    b Inclusion of the results from the above mentioned measurements into a propagation model of the northerly

    ionosphere (i.e. those regions of the ionosphere located poleward of, and including, the mid-latitude trough

    and the use of this model to predict the coverage expected from transmitters where the signals impinge on the

    This report aims at giving a legislative aspect to the many rules that govern the activities of the back-end of the fuel cycle in France. These activities concern the unloading of spent nuclear fuels, their reprocessing, storage, recycling and definitive disposal. The following points are reviewed and commented: the management of non-immediately reprocessed fuels (historical reasons of the 'all wastes reprocessing' initial choice, evolution of the economic and political context, the future reprocessing or the definitive disposal of spent fuels in excess); the inevitable long-term storage of part of the spent fuels (quantities and required properties of long-term stored fuels, the eventuality of a definitive disposal of spent fuels); the criteria that long-term storage facilities must fulfill (confinement measures, reversibility, surveillance and control during the whole duration of the storage); storage concept to be retained (increase of storage pools capacity, long-term storage in pools of reprocessing plants, centralized storage in pools, surface dry-storage on power plant sites, reversible underground storage, subsurface storage and storage/disposal in galleries, surface dry-storage facilities); the preliminary studies for the creation of long-term storage facilities (public information, management by a public French organization, clarifying of the conditions of international circulation of spent fuels); problems linked with the presence of foreign spent fuels in France (downstream of the reprocessing cycle, foreign plutonium and wastes re-shipment); conclusions and recommendations.

    The default of the obligation of information, which should only be a deontological fault, had begun to intrude on the area of responsibility, whether it be criminal or indeed civil. 'Ethical' responsibility took over a 'technical' responsibility limited by the primacy of fault. The law of March 4, 2002 prepared the ground for a return of this sword of Damocles towards its natural area, that is to say deontological fault which comes within ordinal jurisdictions. Thus the main contribution of this law is to be found in the definition of medical responsibility which, by limiting responsibility to a technical fault, seems to rule out the default of the obligation of information. The law of March 4, 2002 has not stirred up the content of the obligation of information for all that. The question of the information on exceptional risks is the only one to have noticeably evolved, since information now concerns only predictable risks. Therefore, the law of March 4, 2002, in no way leads to the death of the obligation of information, quite the reverse: the quality requirements in the information of the patient are even reinforced in some of their aspects, but in compensation for these requirements, there is no exacerbated responsibility anymore.

    This work studies the possibility of using high atomic number compound semiconductors, like lead telluride and cadmium telluride as to realize nuclear radiation detectors, specially in gamma ray spectrometry because of their high absorption coefficient. The problems related to the preparation of binary compounds are exposed. Experiments on PbTe show the influence of the conditions of preparation on the electrical properties of the semiconductor which are greatly dependent on the stoichiometry of the compound. PbTe surface-barrier diodes were realized and have been used to study the surface properties of this semiconductor. These diodes cannot detect nuclear radiations because of the too weak resistivity of our material. Different types of devices made of Cd Te have been studied. One of these diodes has been used as an alpha particle detector. We explain the relative poor performances of that detector by the presence of lattice defects in Cd Te where charge carriers may recombine themselves. By analysing the properties of gold diffused Cd Te diodes we identified this defect, the cadmium vacancy, the presence of which is due to the deviation from stoichiometry during the preparation of the material.

This report is intended to be used by environmental staff in the evaluation of BSC work packages during the annual risk-based planning process. This report shall be fully reviewed and revised annually during the annual work planning process to reflect changes in BSC operations, facilities, and scope of work. Planned BSC work will be evaluated to determine if the work is covered by a previously defined activity, product or service (see Table 2); if work activities require redefinition or addition of a new activity; and if the significant evaluation for each environment aspect is still valid based on scope of planned work. New workscope initiated during the fiscal year through the Baseline Change Proposal process (i.e., not as part of the annual work plan) also will be reviewed for new environmental aspects and determination of whether the new workscope would change the significance rating of any environmental aspect. If a new environmental aspect is identified in a new work activity, product, or service but the aspect is not determined to be significant (see Section 4), then this report can be changed through an interim change notice (ICN). This report can be changed five times through an ICN before a full revision is required. However, if new workscope causes an environmental aspect to be graded as significant using the evaluation process in Section 4, this report shall be revised though a full review and revision

    Research in the design of aspect-oriented programming languages requires a workbench that facilitates easy experimentation with new language features and implementation techniques. In particular, new features for AspectJ have been proposed that require extensions in many dimensions: syntax, type...... checking and code generation, as well as data flow and control flow analyses. The AspectBench Compiler (abc) is an implementation of such a workbench. The base version of abc implements the full AspectJ language. Its frontend is built, using the Polyglot framework, as a modular extension of the Java...... language. The use of Polyglot gives flexibility of syntax and type checking. The backend is built using the Soot framework, to give modular code generation and analyses. In this paper, we outline the design of abc, focusing mostly on how the design supports extensibility.

    Solutions of stable free radicals of the nitroxide type have been studied as a function of temperature. In the plastic or globular state, the cyclohexane molecules have rapid rotational and diffusional movements. They transmit this movement to dissolved free radicals. Conversely, measurements by electron spin resonance of the absolute movement of the radicals, and by electron nuclear double resonance of their movement relative to the cyclohexane molecules give very precise methods for local analyses of the movement present in the cyclohexane matrix. The principle of these techniques makes up the 'radical probe method'. (author) [French] Des solutions de radicaux libres stables, du type nitroxyde dans le cyclohexane ont ete etudiees, en fonction de la temperature. Les molecules de cyclohexane, dans l'etat plastique ou globulaire, sont animees de mouvements rapides de rotation sur elles-memes et de diffusion. Elles transmettent leur mobilite aux radicaux libres dissous. Reciproquement, la mesure du mouvement absolu des radicaux, a l'aide de la resonance paramagnetique electronique, et celle du mouvement relatif des radicaux et des molecules de cyclohexane par double resonance electronique-nucleaire, constituent des methodes tres precises pour analyser localement les mouvements presents dans la matrice de cyclohexane. Ce principe et ces techniques constituent la 'methode de la sonde radicalaire'. (auteur)

    We have carried out the synthesis of: - phenanthrene - its five monomethyl derivatives - three dimethyl derivatives - two trimethyl derivatives. We have then purified these products as well as a certain number of others obtained from various sources. We have been able to obtain in the majority of cases, a purity of 99.5 per cent or over, these figures being obtained by low voltage mass spectrometry. Finally we have recorded the infrared, ultraviolet, nuclear magnetic resonance and mass spectra of these products for which an atlas has been drawn up. (author) [French] Nous avons realise la synthese: - du phenanthrene - de ses cinq derives monomethyles - de trois de ses derives dimethyles - de deux de ses derives trimethyles. Nous avons ensuite purifie ces produits ainsi qu'un certain nombre d'autres que nous avons obtenus de sources differentes. Nous avons pu atteindre, dans la plupart des cas, une purete egale ou superieure a 99,5 pour cent, chiffres determines par la spectrometrie de masse a basse tension. Enfin, nous avons enregistre les spectres infrarouges, ultraviolets, de resonance magnetique nucleaire et de masse de ces produits dont nous avons fait un atlas. (auteur)

  6. DNA vaccines: safety aspect assessment and regulation.

    For licensing purposes, besides the immunogenic aspects, deoxyribonucleic acid (DNA) vaccines present safety considerations that must be critically assessed during preclinical or/and clinical safety studies. The major concerns with regard to safety are integration of the plasmid DNA into the host genome, adverse immunopathological effects, the formation of anti-DNA antibodies resulting in auto-immune disease and the use of novel molecular adjuvants. Moreover, for veterinary vaccines intended to be used in husbandry animals, food safety aspects will become an important issue. All new vaccine candidates should therefore be thoroughly tested in target animals, keeping in mind that for food producing animals, the products will be consumed. Finally, a further safety aspect of interest concerns the possible spread of genetic material to the environment, by the potential transformation of the environmental microflora with only a few copies of complete or fragmented plasmid. These are issues that need to be considered in the final scientific decisions underpinning the registration of vaccines. Thus, to establish criteria for guidance and regulations for industry and licensing authorities, a project has been initiated to assess such risks of plasmid DNA vaccinations. Major emphasis will be placed on aspects such as the biodistribution of plasmid in vaccinated animals. This paper is intended as a contribution to the debate on the use of biotechnology in the future and should facilitate further discussions on the various safety aspects of DNA-based immunisations.

  7. Fuel cell systems and production aspects

    Blomen, L.J.M.J. [Blomenco, Rumpt (Netherlands)

    1995-02-01

    Attention is paid to some system integration and production aspects of fuel cell systems. After an introduction of the main performance differences of fuel cell systems with different types of fuel cells, and the causes for such differences, a few aspects of building up sub-systems towards large and small capacity fuel cell systems are being discussed. Subsequently, some production aspects are being highlighted: the concept of an automated plant and automated plant contracting, the trends towards greater simplicity m reactors, and a systematic evaluation of the differences in fuel processing steps required in systems with different types of fuel cells. In this section also the cost aspects of a total plant contracting project are being discussed. As a next step, some emphasis has been placed on system integration aspects, explaining that hydrogen purification does not always `destroy` system efficiency, and can be used in dispersed hydrogen generation concepts. Advanced system integration concepts include simplified flow sheet design, in which instead of special dedicated rotating equipment standard gas turbine rotary components are being employed. As an example, it is claimed that gas turbine - fuel cell combinations can be made with very high electrical efficiencies. 5 figs., 2 tabs.

    high-power reactors. (author) [French] Les chambres d'ionisation sont actuellement les detecteurs les mieux adaptes au controle des reacteurs nucleaires par des mesures neutroniques. Nous avons cru bon de rappeler quelques generalites concernant la dynamique des reacteurs, les differents procedes de detection des neutrons, le fonctionnement des chambres d'ionisation et les methodes de mesure utilisees. Notre contribution aux techniques de controle des reacteurs consiste d'une part en une tentative de synthese des facteurs intervenant dans le fonctionnement des chambres d'ionisation, l'etude de ces facteurs, et d'autre part l'elaboration de chambres d'ionisation a fission et a bore permettant de suivre la marche d'un reacteur du demarrage jusqu'a la puissance maximale. Dans le domaine des chambres a fission, nous avons en particulier ameliore les techniques de depot d'oxyde d'uranium sur l'aluminium et realise la mise au point de depots par electrolyse sur d'autres metaux: acier inoxydable, cuivre, molybdene, nickel, tantale, titane, kovar, tungstene et beryllium. Nous avons elabore plusieurs types de chambres a fission servant au demarrage des reacteurs: un type de performances moyennes actuellement utilise dans les piles francaises un type a haute sensibilite un type a haute temperature qui a fonctionne jusqu'a 600 deg. C. En ce qui concerne les chambres a bore, nous avons etudie les perturbations apportees dans les mesures par l'exposition des chambres a d'importants flux de neutrons et a un rayonnement {gamma} intense. Cette exposition produit une modification des proprietes des materiaux constitutifs et la production dans les chambres d'un bruit de fond qui peut gener considerablement les mesures neutroniques. Nous avons montre que la technique de compensation permettait de limiter l'importance de ce bruit de fond et d'augmenter ainsi la plage de fonctionnement des

    Full Text Available Cohesion and metaphor are the unique and interesting parts of language aspects in Andhabhuan text to research. They are quite dominant aspects in the story in developing its literature aesthetic. This research is based on the arts technical and analytical method. The result of the research on those two aspects shows that traditional aesthetic style in arts, as described in Andabhuana verses emphasize on the reference, meaning, selection and variation of words. The language parts used are aimed at bringing the text ideology to humanity perspective, especially the ?iwatattwa values as parts of Hindu teaching. Hence the cohesion and metaphor in Andabhuana text  are  semiotic description to transform to Balinese Hindus as most of them follow ?iwatattwa belief.

  10. Transport in a small aspect ratio torus

    International Nuclear Information System (INIS)

    White, R.B.; Gates, D.A.; Mynick, H.E.

    2005-01-01

    Transport theory in toroidal devices often assumes large aspect ratio and also assumes the poloidal field is small compared to the toroidal field. These assumptions result in transport which in the low collision rate limit is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device the gyro radius may be larger than the banana excursion, resulting in significant deviations from the standard neoclassical predictions. In this paper we report numerical simulation of diffusion in low and high beta low aspect ratio equilibria. We also sketch an analytic theory. The diffusion, which we refer to as omniclassical, is a combination of neoclassical and properly averaged classical effects, and can be two or three times the neoclassical value. Good agreement of the analytic theory with numerical simulations is obtained. (author)

  11. Two often disregarded aspects of Foucault's pendulum

    Pérez, José-Philippe; Pujol, Olivier

    2015-01-01

    This paper revisits the famous Foucault's pendulum by highlighting two often-disregarded aspects in mechanics courses. The first one concerns the existence of a local accelerated reference frame to express the law of dynamics without the Coriolis force. The second aspect deals with the geometrical phase that appears in pendulum dynamics. This last point, which could appear banal, should be related to analogous consideration in quantum physics. It is also linked to vectorial parallel transport of the pendulum angular momentum eigenvector. Numerical simulations with MATLAB are proposed. (paper)

    The topic of energy crops, namely of those crops designed to produce biomass to transform into ethanol, has been explored, in Italy and abroad, in all its technical and agronomical aspects. The microeconomic aspect, including the evaluation of convenience for the farmer in adopting such crops, is, on the contrary, less well researched. RENAGRI has developed a research methodology able to give information about the level of convenience of two energy crops (Sweet Sorghum and Topinambour) and has applied it to different Italian agricultural situations, in order to verify the existence of conditions favourable to the cultivation of the two crops, or to indicate the necessity of eventual subvention.

    Full Text Available Purpose: In the past several decades of Islamic banking and fi nance (IBF activity in many countries, notable literature on this topic has been produced all over the world. By analyzing this IBF literature, this study investigates and highlights some ignored aspects of IBF activities. Methodology: Academic IBF literature includes defending the plausibility of IBF as a part of Islamic economics; theoretical analysis regarding some advantages of IBF compared with conventional systems, suggesting some methods for performing IBF; and concentration on introducing fi nancial instruments and innovations in Islamic financial markets. After reviewing them, they are classifi ed as high ranking journal papers and graduate dissertations that were written on Islamic economics in I.R. Iran during the past three decades. Then they are analyzed via analytical methods and descriptive statistics to investigate the ignored aspects of IBF. Findings: Through this systemic study of Islamic banking, real and not skeletal adaptation of Islamic contracts, Islamic goals of Islamic economy, Islamic and ethical values, and justice and poverty reduction are some of the more important neglected aspects in IBF activities. Research Implications: Focusing on these areas in future research could improve the performance of IBF as part of the Islamic economic system and guide IBF activities to the real nature of Islam (Islamicity. Originality: Besides reviewing and classifying the academic literature on IBF, the study is unique in focusing on the neglected aspects of IBF because it is very important and infl uential to distinguish IBF from non-IBF activities.

    The AREVA 'Values Charter' reaffirmed the priority that must be given to the requirement for a very high level of safety, which applies in particular to the nuclear field. The purpose of this Nuclear Safety Charter is to set forth the group's commitments in the field of nuclear safety and radiation protection so as to ensure that this requirement is met throughout the life cycle of the facilities. It should enable each of us, in carrying out our duties, to commit to this requirement personally, for the company, and for all stakeholders. These commitments are anchored in organizational and action principles and in complete transparency. They build on a safety culture shared by all personnel and maintained by periodic refresher training. They are implemented through Safety, Health, and Environmental management systems. The purpose of these commitments, beyond strict compliance with the laws and regulations in force in countries in which we operate as a group, is to foster a continuous improvement initiative aimed at continually enhancing our overall performance as a group. Content: 1 - Organization: responsibility of the group's executive management and subsidiaries, prime responsibility of the operator, a system of clearly defined responsibilities that draws on skilled support and on independent control of operating personnel, the general inspectorate: a shared expertise and an independent control of the operating organization, an organization that can be adapted for emergency management. 2 - Action principles: nuclear safety applies to every stage in the plant life cycle, lessons learned are analyzed and capitalized through the continuous improvement initiative, analyzing risks in advance is the basis of Areva's safety culture, employees are empowered to improve nuclear Safety, the group is committed to a voluntary radiation protection initiative And a sustained effort in reducing waste and effluent from facility Operations, employees and subcontractors are treated alike, and a high level Of know-how is supported by training and skills maintenance. 3 - Transparency and reporting: Areva endeavors to provide reliable and relevant information enabling an objective assessment of the status of nuclear safety in its facilities (incident reporting, annual report of the general inspectorate, annual reporting on occupational safety during nuclear facility operations). 4 - Glossary.

    For a long time, a small group of big powers has been the only holder of nuclear weapons (US, USSR, Great Britain, France and China). Since then, new weapons have come out on the geopolitical scene: Israel, India, Pakistan, and some others remain uncertain and generate a worrying atmosphere (North Korea, Iran..). But what is the real risk with nuclear proliferation? Should we dread about it? Is nuclear terrorism a real threat? What are the political stakes of nuclear weapons? Is disarmament a real solution? These are some of the questions that the author answers in a precise and clear manner in this book. Contents: 1 - from monopoly to proliferation: who owns nuclear weapons today, why is it so coveted, is it easy to make one?; 2 - the newcomers: what do we really know about the Iranian nuclear programme, Iran and North Korea: between negotiation and confrontation; 3 - international control and regulation: do we have reliable information, how do we know what we know, Iraq: was there a 'lie' somewhere, who are the states who have renounced nuclear weapons?; 4 - the future: is there still a nuclear warfare risk, what if Pakistani weapons fall into islamic hands, is nuclear terrorism a fantasy or a real risk?

    After many years of low profile business in the USA, MRI is back. Improvements are focused on high field magnets and on low field magnets. The former, are dedicated to high quality imaging. The new scanners are more and more efficient because of the spreading use of real time imaging. They can do now, procedures that just could not be imagined some years ago. Vascular imaging is done routinely. Abdominal imaging in apnea of EPI, perfusion and diffusion imaging, and, last not least, all the field of functional imaging are on the verge of coming out. The new magnets unveiled in 1997 are lighter, smaller, more, user friendly, less impressive for patients subject to claustrophobia. They also need less helium to operate and less space to be sited. The latter, are dedicated to interventional procedures. The new magnets are wide opened and a lot of companies show off. Though Picker unveiled a new light superconductive 0.5 Tesla magnet, it seems that this kind of machines are about to disappear. No significant progress was noticed in the field of dedicated MRI devices. Some features can be highlighted: the new Siemens short bore and its table integrates the Panoramic Array Coil Concept. It will allow simultaneous scanning with up to four coils; the excellent homogeneity of the new Picker magnet that will allow spectroscopy at 1 Tesla; the twin gradients of the Elscint Prisma that will open the field of microscopy MRI; the Philips `floppy gradients` that could speed up 4 or 6 times, the time needed for imaging; some new sequences sensitive to temperature are studied as WIP; a lot of work is achieved on 3 or 4 Tesla scanners etc. (author)

    A quick review of the nuclear safety at EDF may be summarized as follows: - the nuclear safety at EDF maintains at a rather good standard; - none of the incidents that took place has had any direct impact upon safety; - the availability remained good; - initiation of the floor 4 reactor generation (N4 unit - 1450 MW) ensued without major difficulties (the Civaux 1 NPP has been coupled to the power network at 24 december 1997); - the analysis of the incidents interesting from the safety point of view presents many similarities with earlier ones. Significant progress has been recorded in promoting actively and directly a safe operation by making visible, evident and concrete the exertion of the nuclear operation responsibility and its control by the hierarchy. The report develops the following chapters and subjects: 1. An overview on 1997; 1.1. The technical issues of the nuclear sector; 1.2. General performances in safety; 1.3. The main incidents; 1.4.

    The Fukushima accident is characterized by a sequence of natural disasters: earthquake and tsunamis that deprived simultaneously 3 reactors from cooling and electrical power for quite a long time. A series of hydrogen explosion has added to the mess. Experts agree to say that certainly nuclear fuel has melt to form corium in all 3 reactors. The accident has contaminated tens of thousand acres of land around the plant and has jeopardized local coastal fishery. The human toll is unexpectedly low: no direct casualty in the population but several suicides among the people that was forced to leave their home. 5 people from the plant staff died certainly from the consequences of the tsunami.

    After a first article recalling the creation of Areva and difficulties faced by this company which resulted in some kind of backward step, two articles address evolutions in the energy sector: an overview of recent evolutions (USA to become the first oil producer in the world, the OPEC policy, the distribution of nuclear energy production in the world, world consumption in 2014, the French law on energy transition, the dilemma associated with energy transition in Germany, regulated gas prices in France), and a discussion of the perspective for electricity by 2050 (100 per cent renewable? And why not 100 per cent nuclear?). Four articles concern nuclear activities: recent events in the mining and fuel fabrication sectors (an uranium bank in Kazakhstan, contract for Areva in Ukraine, uranium enrichment in South Korea, Saudi Arabia, India, China, Japan, USA), recent events regarding nuclear reactors (in France, UK, Sweden, Czech Republic, Russia, Turkey, South Korea), overview of activities and events related to the back-end of the fuel cycle (in France, Germany, China, USA and Japan), and a presentation of Savannah River MFFF plant (MOX Fuel Fabrication Facility). Two article address issues related to nuclear and society: a discussion on the possibility to eat irradiated food products, and the issue of the Iranian nuclear industry with respect to non-proliferation.

    The first French plutonium-making reactors G1, G2 and G3 built at Marcoule research center are linked to a power plant. The G1 electrical output does not offset the energy needed for operating this reactor. On the contrary, reactors G2 and G3 will each generate a net power of 25 to 30 MW, which will go into the EDF grid. This power is relatively small, but the information obtained from operation is great and will be helpful for starting up the power reactor EDF1, EDF2 and EDF3. The paper describes how, previous to any starting-up operation, the tests performed, especially those concerned with the power plant and the pressure vessel, have helped to bring the commissioning date closer.

    After a first article which comments the situation of EDF which is a serious matter of concern, notably due to the current context for the energy sector and market, and which notably comments the issue of the Hinkley Point project, an article proposes an overview of recent evolutions (oil price recent evolutions, perspectives for gas and coal, the abundance and availability of hydroelectric energy). Three articles concern nuclear activities: recent events about reactors (EU policy, decisions, projects and events in Switzerland, Sweden, UK about Hinkley Point, Fessenheim, Chernobyl, Poland, Europe about reactor lifetime extension, Russia, in Saudi Arabia and South Korea about the Korean APR-1400 technology, in Bangladesh, in India, Japan and USA), about the back-end of the fuel cycle and decommissioning activities (brief focus on the Cigeo project, foreign storages, discussion of the warehousing-transport issue, dismantling activities in France, recycling in France, Russia, China, Taiwan and the UK, evolution of the MFFF plant in Savannah River), and a comment of the main qualities of nuclear energy. Articles comment issues concerning the relationship between nuclear and society with a comment on the French approach (nuclear and precaution principle, anti-nuclear position of French media, crucial role of operators for nuclear safety), and a comment on the evolution of human lifetime expectation statistics in France and its possible relationship with technology when taking accidents related to energy sources into account. An article analyses the German situation with respect to energy. A last article briefly discusses some terminological confusion between energy and electricity, and between produced energy and available power

  20. QCD-instantons at LHC. Theoretical aspects

    International Nuclear Information System (INIS)

    Petermann, M.

    2007-06-01

    Instantons are nonperturbative, topologically nontrivial field configurations, which occur in every nonabelian gauge theory. They can be understood as tunneling processes between topologically distinct vacua. Although being a basic theoretical aspect of the Standard Model, a direct experimental verification of instanton processes is still lacking. In this thesis the general discovery potential for QCD-instantons at the LHC is studied in detail by means of instanton perturbation theory. In this context the close correspondence between the leading instanton induced processes at HERA and at LHC becomes important. Essential aspects and differences to deep inelastic scattering can already be revealed by studying the simplest process. Based on these results inclusive cross sections are calculated including the emission of final state gluons. Compared to deep inelastic scattering, a large enhancement of the cross section is found.

    2001-01-01

    Radiation protection aspects relevant to medical accelerators are discussed. An overview is first given of general safety requirements. Next. shielding and labyrinth design are discussed in some detail for the various types of accelerators, devoting more attention to hadron machines as they are far less conventional than electron linear accelerators. Some specific aspects related to patient protection are also addressed. Finally, induced radioactivity in accelerator components and shielding walls is briefly discussed. Three classes of machines are considered: (1) medical electron linacs for 'conventional' radiation therapy. (2) low energy cyclotrons for production of radionuclides mainly for medical diagnostics and (3) medium energy cyclotrons and synchrotrons for advanced radiation therapy with protons or light ion beams (hadron therapy).

    1980-09-01

    Solar energy technologies have environmental effects, and these may be positive or negative compared with current ways of producing energy. In this respect, solar energy technologies are no different from other energy systems. Where solar energy technologies differ is that no unresolvable technological problems (e.g., CO/sub 2/ emissions) or sociopolitical barriers (e.g., waste disposal, catastrophic accidents) have been identified. This report reviews some of the environmental aspects of solar energy technologies and ongoing research designed to identify and resolve potential environmental concerns. It is important to continue research and assessment of environmental aspects of solar energy to ensure that unanticipated problems do not arise. It is also important that the knowledge gained through such environmental research be incorporated into technology development programs and policy initiatives.

  6. Analytical aspects of hydrogen exchange mass spectrometry

    Science.gov (United States)

    Engen, John R.; Wales, Thomas E.

    2016-01-01

    The analytical aspects of measuring hydrogen exchange by mass spectrometry are reviewed. The nature of analytical selectivity in hydrogen exchange is described followed by review of the analytical tools required to accomplish fragmentation, separation, and the mass spectrometry measurements under restrictive exchange quench conditions. In contrast to analytical quantitation that relies on measurements of peak intensity or area, quantitation in hydrogen exchange mass spectrometry depends on measuring a mass change with respect to an undeuterated or deuterated control, resulting in a value between zero and the maximum amount of deuterium that could be incorporated. Reliable quantitation is a function of experimental fidelity and to achieve high measurement reproducibility, a large number of experimental variables must be controlled during sample preparation and analysis. The method also reports on important qualitative aspects of the sample, including conformational heterogeneity and population dynamics. PMID:26048552

    Full Text Available Writing for Professional Purposes is considered as a means of communication between professionals who belong to two communities that have different languages, but share the same knowledge or expertise. The article gives a hint on how writing for specific purposes evolved to give rise to the creation of Writing for Professional Purposes. The social, cultural and cognitive aspects are an essential part of Writing for Professional Purposes since the physical act of writing cannot be considered only a result or product of the knowledge the individual possesses but also a social and cultural act. Therefore, the social and cultural aspects of writing explains the specificities and the intricacies of the effects these aspects have on writing for it is considered as an inseparable part of social and cultural groups. On the other hand, the cognitive aspect of writing explains and emphasizes the mental activities of the individual during the decision-making process while he/she is writing planning and editing their material having in mind the audience. On the same line of reasoning, writing for professional purposes in a second language means that the writer has to consider the audience twice; first, there is an audience who shares the same knowledge or expertise and second, the audience does not have the same language. Consequently, writing in another language that is not the first language with a specific jargon as well as a specific grammatical structure brings about a lot of difficulties. Hence, writing in professional contexts in the mother tongue implies only writing in a specialized version of a language already known to the writer, but writing in a target language means that the writer has to learn the target language and the specialized version of that language.

    Female circumcision is a very old tradition still widely practised in Africa. The extent of female circumcision ranges from resection of the clitoridal prepuce (= sunnitic circumcision) to resection of labia minora and majora as well as clitoridectomy (= pharaonic circumcision). Wound approximation by sutures or scar contraction may cause partial closure of the vaginal orifice (= infibulation). Historical, sociological as well as medical aspects are discussed and reconstructive procedures described.

    The author debates public health aspects of food irradiation. The effect of food irradiation as a convenience to the consumer is discussed, i.e. the prevention of food deterioration and also the prevention of disease that could be passed on to the consumer by ingestion. On the other hand, the effects that could possibly be created by the application of radiation are also evaluated using toxicological and microbiological considerations. (Auth.)

    1992-01-01

    When the Iraqi troops were forced to leave Kuwait, they left behind them the greatest oil catastrophe human beings have ever experienced. Fire plumes of tons of gases of principal pollutants, hydrocarbons, soot and associated metals were ejected up to a height of about 5 km. The retreating forces blew off about 1200 wells all over Kuwait fields. Of these 1200 wells, 614 are on fire. Four firefighting companies were hired to start work immediately after the liberation of Kuwaiti to control these wells. Three of these companies were from the U.S.A. and one from Canada. The number of these companies steadily increased along with logistical support. There are now 28 teams made up of private and multinational companies. This paper will concentrate on two main aspects. The first part will focus on the up-to-date engineering aspects of bringing the blown-out wells under control, focusing on oil well fires and the difficulties encountered, such as equipment availability, ordnance clearance and logistical support. The paper then describes the procedures used to control the wells, and the steps taken to reach this aim are presented. Finally the number of wells controlled, area-wise in different fields, with their original status, is also introduced. The second part will concentrate on the environmental aspects, covering the impact of the plumes on air quality, air pollution and health. The paper then discusses the effect on marine environment, vegetation and the soil. Finally, a forecast, conclusions and recommendations are presented. (author)

  9. Stable Aspects in Robot Software Development

    Full Text Available The paper investigates the concept of software “stability” applied to robot systems. We define “stable” a family of systems modelled, designed and implemented so that specific applications of the family may be developed re-using, adapting and specializing knowledge, architecture and existing components. During the last few years, many ideas and technologies of software engineering (e.g. modularity, OO development and design patterns were introduced in the development of robotic systems to improve the “stability” property. All these ideas and technologies are important. Nevertheless, they model robotic systems along a unique direction: the functional decomposition of parts. Unfortunately, there are concerns of robotic systems that relate to the systems as a whole hence crosscutting their modular structure. The Aspect Oriented Software Development is a recently emerged approach for modelling, designing and encapsulating the above-mentioned crosscutting concerns (aspects. We contend that stability must be based on a careful domain analysis and on a multidimensional modelling of different and recurring aspects of robot systems.

    To correlate quality of life of children in terms of sleep, with their oral language skills, auditory processing and orofacial myofunctional aspects. Nineteen children (12 males and seven females, in the mean age 9.26) undergoing otorhinolaryngological and speech evaluations participated in this study. The OSA-18 questionnaire was applied, followed by verbal and nonverbal sequential memory tests, dichotic digit test, nonverbal dichotic test and Sustained Auditory Attention Ability Test, related to auditory processing. The Phonological Awareness Profile test, Rapid Automatized Naming and Phonological Working Memory were used for assessment of the phonological processing. Language was assessed by the ABFW Child Language Test, analyzing the phonological and lexical levels. Orofacial myofunctional aspects were evaluated through the MBGR Protocol. Statistical tests used: the Mann-Whitney Test, Fisher's exact test and Spearman Correlation. Relating the performance of children in all evaluations to the results obtained in the OSA-18, there was a statistically significant correlation in the phonological working memory for backward digits (p = 0.04); as well as in the breathing item (p = 0.03), posture of the mandible (p = 0.03) and mobility of lips (p = 0.04). A correlation was seen between the sleep quality of life and the skills related to the phonological processing, specifically in the phonological working memory in backward digits, and related to orofacial myofunctional aspects.

    Sustainable development has been recognized globally as one of the major driving forces towards the current technological innovations. To achieve sustainable development and attain its associated goals, it is very important to properly address its concerns in different aspects of technological innovations. Several industrial sectors have enjoyed productivity and economic gains due to advent of automation technology. It is important to characterize sustainability for the automation technology. Sustainability is key factor that will determine the future of our neighbours in time and it must be tightly wrapped around the double-edged sword of technology. In this study, different impacts of automation have been addressed using the ‘Circles of Sustainability’ approach as a framework, covering economic, political, cultural and ecological aspects and their implications. A systematic literature review of automation technology from its inception is outlined and plotted against its many outcomes covering a broad spectrum. The study is more focused towards the social aspects of the automation technology. The study also reviews literature to analyse the employment deficiency as one end of the social impact spectrum. On the other end of the spectrum, benefits to society through technological advancements, such as the Internet of Things (IoT) coupled with automation are presented.

    2016-12-01

    Disorders of sex development (DSD) is a congenital condition in which the development of chromosomes, gonads, hormones, and reproductive structures are atypical. DSD brings with it a psychological impact on the affected individual and their families. The consensus statement on management of DSD strongly advised an integrated and multidisciplinary approach in providing care to the affected individuals. Studies have been conducted focusing on medical intervention, and more recently, there is increasing attention paid to psychological aspects of DSD. However, studies reporting cultural aspects of DSD are lacking. This review provides an overview on how culture impacts the affected individuals in coping with DSD and making decisions with regard to gender assignment or reassignment, help-seeking behavior for medical treatments, attitudes toward medical treatment, religious beliefs, and values concerning marriage and fertility. The involvement of social scientists is needed to study sociocultural aspects of DSD from more diverse cultures, to help affected individuals and their families in gaining better social acceptance.

  16. Myocardial Na,K-ATPase: Clinical aspects

    Science.gov (United States)

    Kjeldsen, Keld

    2003-01-01

    The specific binding of digitalis glycosides to Na,K-ATPase is used as a tool for Na,K-ATPase quantification with high accuracy and precision. In myocardial biopsies from patients with heart failure, total Na,K-ATPase concentration is decreased by around 40%; a correlation exists between a decrease in heart function and a decrease in Na,K-ATPase concentration. During digitalization, around 30% of remaining pumps are occupied by digoxin. Myocardial Na,K-ATPase is also influenced by other drugs used for the treatment of heart failure. Thus, potassium loss during diuretic therapy has been found to reduce myocardial Na,K-ATPase, whereas angiotensin-converting enzyme inhibitors may stimulate Na,K pump activity. Furthermore, hyperaldosteronism induced by heart failure has been found to decrease Na,K-ATPase activity. Accordingly, treatment with the aldosterone antagonist, spironolactone, may also influence Na,K-ATPase activity. The importance of Na,K pump modulation with heart disease, inhibition in digitalization and other effects of medication should be considered in the context of sodium, potassium and calcium regulation. It is recommended that digoxin be administered to heart failure patients who, after institution of mortality-reducing therapy, still have heart failure symptoms, and that the therapy be continued if symptoms are revealed or reduced. Digitalis glycosides are the only safe inotropic drugs for oral use that improve hemodynamics in heart failure. An important aspect of myocardial Na,K pump affection in heart disease is its influence on extracellular potassium (Ke) homeostasis. Two important aspects should be considered: potassium handling among myocytes, and effects of potassium entering the extracellular space of the heart via the bloodstream. It should be noted that both of these aspects of Ke homeostasis are affected by regulatory aspects, eg, regulation of the Na,K pump by physiological and pathophysiological conditions, as well as by medical

  17. Noise of Embedded High Aspect Ratio Nozzles

    Bridges, James E.

    2011-01-01

    A family of high aspect ratio nozzles were designed to provide a parametric database of canonical embedded propulsion concepts. Nozzle throat geometries with aspect ratios of 2:1, 4:1, and 8:1 were chosen, all with convergent nozzle areas. The transition from the typical round duct to the rectangular nozzle was designed very carefully to produce a flow at the nozzle exit that was uniform and free from swirl. Once the basic rectangular nozzles were designed, external features common to embedded propulsion systems were added: extended lower lip (a.k.a. bevel, aft deck), differing sidewalls, and chevrons. For the latter detailed Reynolds-averaged Navier-Stokes (RANS) computational fluid dynamics (CFD) simulations were made to predict the thrust performance and to optimize parameters such as bevel length, and chevron penetration and azimuthal curvature. Seventeen of these nozzles were fabricated at a scale providing a 2.13 inch diameter equivalent area throat." ! The seventeen nozzles were tested for far-field noise and a few data were presented here on the effect of aspect ratio, bevel length, and chevron count and penetration. The sound field of the 2:1 aspect ratio rectangular jet was very nearly axisymmetric, but the 4:1 and 8:1 were not, the noise on their minor axes being louder than the major axes. Adding bevel length increased the noise of these nozzles, especially on their minor axes, both toward the long and short sides of the beveled nozzle. Chevrons were only added to the 2:1 rectangular jet. Adding 4 chevrons per wide side produced some decrease at aft angles, but increased the high frequency noise at right angles to the jet flow. This trend increased with increasing chevron penetration. Doubling the number of chevrons while maintaining their penetration decreased these effects. Empirical models of the parametric effect of these nozzles were constructed and quantify the trends stated above." Because it is the objective of the Supersonics Project that

    Rapid application growth of complex Information and Communication Technologies (ICT) in every society and state infrastructure as well as industry has revealed vulnerabilities that eventually have given rise to serious security breaches. These vulnerabilities together with the course of the breaches from cause to consequence are gradually about to convince the field experts that ensuring the security of ICT-driven systems is no longer possible by only relying on the fundaments of computer science, IT, or telecommunications. Appropriating knowledge from other disciplines is not only beneficial, but indeed very necessary. At the same time, it is a common observation today that ICT-driven systems are used everywhere, from the nuclear, aviation, commerce and healthcare domains to camera-equipped web-enabled cellular phones. The increasing interdisciplinary and inter-sectoral aspects of ICT security worldwide have been providing updated and useful information to the nuclear domain, as one of the emerging users of ICT-driven systems. Nevertheless, such aspects have also contributed to new and complicated challenges, as ICT security for the nuclear domain is in a much more delicate manner than for any other domains related to the concept of safety, at least from the public standpoint. This report addresses some important aspects of ICT security that need to be considered at nuclear facilities. It deals with ICT security and the relationship between security and safety from a rather different perspective than usually observed and applied. The report especially highlights the influence on the security of ICT-driven systems by all other dependability factors, and on that basis suggests a framework for ICT security profiling, where several security profiles are assumed to be valid and used in parallel for each ICT-driven system, sub-system or unit at nuclear facilities. The report also covers a related research topic of the Halden Project with focus on cyber threats and

    Institutional and socioeconomic aspects of water supply Within the project CC-WaterS the participating researchers of the Vienna University of Economics and B.A. have been responsible for the analysis of the socioeconomic aspects related to water supply and climate change, the assessment of future water demands in the City of Vienna, as well as an estimation of economic consequences of possible water shortages and possible scope for the introduction of new legal guidelines. The institutional and socioeconomic dimensions of drinking water and sanitation systems are being examined by utilisation of different prognostic scenarios in order to assess future costs of water provisioning and future demands of main water users, thus providing an information basis and recommendations for policy and decision makers in the water sector. These dimensions, for example, include EU legislation - especially the Water Framework Directive -, national legislations and strategies targeted at achieving sustainability in water usage, best practices and different forms of regulating water markets, and an analysis of the implications of demographic change. As a basis this task encompasses research of given institutional, social, and legal-political structures in the area of water supply. In this course we provide an analysis of the structural characteristics of water markets, the role of water prices, the increasing perception of water as an economic good as well as implications thereof, the public awareness in regard to climate change and water resources, as well as related legal aspects and involved actors from regional to international level; and show how water resources and the different systems of water provisioning are affected by (ideological) conflicts on various levels. Furthermore, and in order to provide a solid basis for management recommendations related to climate change and water supply, an analytical risk-assessment framework based on the concepts of new institutional

    The development of a facsimile camera to serve as the antenna aspect system for the second generation Radio Astronomy Explorer Satellite designated RAE-B is summarized. The camera system consists of two cameras and a data encoder. The program deliverables were two flight cameras, a flight encoder and one spare flight encoder. The RAE-B satellite was originally intended for an earth orbit mission and the facsimile subsystem characteristics were specified with this in mind. Subsequently the flight mission was changed to orbit the moon; however the change occurred too late to significantly influence the facsimile system design. Therefore, this report considers only compliance of the system to earth orbit requirements.

    Blindfold chess is a very good task environment to study skill-based mental images or skilled imagery. Seven experiments providing information on different aspects of skilled imagery in blindfold chess were made. In all experiments very clear skill-related differences in the operation of chess-specific materials could be found. It will also be argued that chess-specific patterns or chunks are important in skilled subjects' construction of images and the operation of these images relies on the cooperation of visual working memory and long-term memory.

    2011-04-01

    Full Text Available Application of computer technology in the Earth science has led to the creation and development of new scientific disciplines, particularly digital cartography and GIS. This paper describes the application of GIS from several points of view such as: multi-scale, multi-thematic, multi-viewing, accommodation to standard software platforms and multi-user data accesses. Introduction The premise of a successful usage of topographic data nowadays implies their disposal in a digital form and organisation in a modern way, suitable for further computer processing. It is a unanimous opinion that it can be successfully completed only through creating data basis of space developing GIS. The theme of the written work is the development and application of GIS, and management of topographic data in accordance with international standards and users' needs. Moving to digital technology of creating and using topographic data should not be literal translation of the analogue map into a digital picture or just the automation of the map making using digital technology. The new method implies the formation of the central topographic data base which would generate displays of arbitrary scales, desired volumes of content, changeable sheet dimensions, various thematic displays, altogether in accordance with users' demands and needs. Digital cartography and GIS The development and application of computers in the area of earth sciences caused the creation of new definitions and disciplines among which are noticeable computer supported cartography and GIS. The computer-supported cartography was in its later phase called digital cartography and it can be used in two ways: like modern technology of date processing about space and like a new discipline. The main principle on which digital cartography as a discipline is based represents the processing and visualization of data about space but with computer supported technology.

    We study quantum aspects of the recently constructed doubly λ-deformed σ-models representing the effective action of two WZW models interacting via current bilinears. We show that although the exact beta-functions and current anomalous dimensions are identical to those of the λ-deformed models, this is not true for the anomalous dimensions of generic primary field operators in accordance with the fact that the two models differ drastically. Our proofs involve CFT arguments, as well as effective σ-model action and gravity calculations.

    Buscaglione, A.

    1991-01-01

    This paper focusses on administrative/bureaucratic problems relative to the licensing of cogeneration plants in Italy. The current stumbling block appears to lie in organizational difficulties relative to the coordination of various Government authorized safety committees responsible for the drafting up of suitable legislation governing cogeneration plant fire safety aspects. The author cites the possible environmental benefits in terms of air pollution abatement that could have been had with the timely start-up of a new 7 MW plant (in Lombardia) still awaiting its go-ahead authorization

    Full Text Available Companies that want to maximize their profits must decide on several elements that influence this aspect. An important role is pricing the product or service offered by the company. In determining the best price for the product, management must take into account several factors such as cost / unit, market characteristics where the product is intended to be placed, consumer needs. Those that make this type of decisions often use price strategies which help enter a particular market. Economists state that there are many types of strategies out of which I will present those strategies that are based on marginal cost, incremental costs, break even and mark-up.

    The neolignans are defined as dimers of allylphenol and propenylphenol between itself or crossed, whose bond does not occur by the 8-8' carbons like lignans. This review centered on stereochemical aspects of the hydrobenzofuran type, a widespread skeleton among neolignans. The chemical structures established based on spectrometric data are registered in the literature. The absolute configurations reported previously were determined by chiroptical techniques. Some chemical transformations with neolignans, performed in previous studies, afforded products which are accumulated in other vegetal species and contributed to assign the unknown stereochemistry of these natural compounds. Possible biosynthetic pathways are also proposed. (author)

    Full Text Available The causes of psychological problems in children with micturition disorders are analyzed and social factors influencing quality of life in a child are considered. The study and understanding of the psychosocial aspects of micturition disorders in children are an important component in the structure of diagnosis and therapy of this pathology. Morbid self-perception in society contributes to further personality neurotization, social maladjustment, and emotional and neurotic disorders. The complexity is that psychological abnormalities may persist much longer even after micturition problems come to an end. The timely participation of a psychologist in patients' rehabilitation has a significant impact on the success of performed therapy.

  20. Safety Aspects of Nuclear Waste Treatment

    International Nuclear Information System (INIS)

    Glubrecht, H.

    1986-01-01

    In the nuclear fuel cycle - like in most other industrial processes - some waste is produced which can be harmful to the environment and has to be stored safely and isolated from the Biosphere. This radioactive waste can be compared with toxic chemical waste under many aspects, but it has some special features, some of which make its handling more difficult, others make it easier. The difficulties are that radioactive waste does not only affect living organisms after incorporation, but also from some distance through its radiation. Therefore this waste has not only to be encapsuled, but also shielded. At higher concentrations radioactive waste produces heat and this has to be continuously derived from the storage area. On the other hand the control of even extremely small amounts of radioactive waste is very much easier than that of toxic chemical waste due to the high sensitivity of radiation detection methods. Furthermore radioactive waste is not persistent like most of the chemical waste. Of course some components will decay only after millennia, but a high percentage of radioactive waste becomes inactive after days, weeks or years. An important feature of safety aspects related to nuclear waste is the fact that problems of its treatment and storage have been discussed from the very beginning of Nuclear Energy Technology - what has not been the case in relation to most other industrial wastes

  2. Operational and materials aspects of aging management

    International Nuclear Information System (INIS)

    Muscara, J.; Vora, J.P.; Moyer, C.E.

    2005-01-01

    Understanding degradation phenomena and managing the detrimental effects of aging are important aspects of commercial nuclear power plant operations. Potential for materials degradation should be considered early in the design and development stages; during manufacturing, construction, and installation; and during all aspects of plant operation and maintenance. This would lead to increased reliability during plant operations, and would reduce the need for mitigating actions and unplanned maintenance. Thus, it is necessary to instill a culture at the technical, administrative, and management levels that continually asks, 'What happens with time?' The answer to this question is central to the continuous safe and economical operation of nuclear power plants. Based on the past 25 years of aging-related research at the U.S. Nuclear Regulatory Commission (NRC), the authors present an overview of the key elements of understanding and managing aging, and how they should be integrated for safe and economical power plant operation. The focus of this paper is hardware-oriented engineering and aging of materials. The paper discusses previous and ongoing NRC research studies on non-destructive examination and materials degradation that can be applied for proactive management of materials degradation and aging during plant operations.

    Osteoporosis is one of the most common disorders in postmenopausal women, affecting the quality of life and increasing the risk for fractures in minor traumas. Changes in the bone microarchitecture causes static changes in the body and affects motility. In this study, we analyzed two groups of women, one with physiological menopause and one with surgically induced menopause. The diagnosis of osteoporosis was suspected based on the clinical symptoms and confirmed by assessing bone mineral density by the dual-energy X-ray absorptiometry (DEXA). Comparing some clinical and biological aspects there was noted that a much higher percentage of women with surgically induced menopause exhibited increases in body mass index, changes in serum lipids, cholesterol, triglycerides, blood glucose, serum calcium, magnesemia and osteocalcin. In contrast, no significant differences were observed in the histopathological aspects of bone tissue examined from these two groups. In all patients, there was identified a significant reduction in the number of osteocytes and osteoblasts, the expansion of haversian channels, reducing the number of trabecular bone in the cancellous bone with wide areola cavities often full of adipose tissue, non-homogenous demineralization of both the compact bone and the cancellous bone, atrophy and even absence of the endosteal, and the presence of multiple microfractures. Our study showed that early surgically induced menopause more intensely alters the lipid, carbohydrate and mineral metabolism, thus favoring the onset of osteoporosis.

  4. Disposal of radioactive waste. Some ethical aspects

    International Nuclear Information System (INIS)

    Streffer, Christian

    2014-01-01

    The threat posed to humans and nature by radioactive material is a result of the ionizing radiation released during the radioactive decay. The present use of radioactivity in medicine research and technologies produces steadily radioactive waste. It is therefore necessary to safely store this waste, particularly high level waste from nuclear facilities. The decisive factors determining the necessary duration of isolation or confinement are the physical half-life times ranging with some radionuclides up to many million years. It has therefore been accepted worldwide that the radioactive material needs to be confined isolated from the biosphere, the habitat of humans and all other organisms, for very long time periods. Although it is generally accepted that repositories for the waste are necessary, strong public emotions have been built up against the strategies to erect such installations. Apparently transparent information and public participation has been insufficient or even lacking. These problems have led to endeavours to achieve public acceptance and to consider ethical acceptability. Some aspects of such discussions and possibilities will be taken up in this contribution. This article is based on the work of an interdisciplinary group. The results have been published in 'Radioactive Waste - Technical and Normative Aspects of its Disposal' by C. Streffer, C.F. Gethmann, G. Kamp et al. in 'Ethics of Sciences and Technology Assessment', Volume 38, Springer-Verlag Berlin Heidelberg 2011.

  5. Safety Aspects in Radioactive Waste Management

    Directory of Open Access Journals (Sweden)

    Peter W. Brennecke

    2007-01-01

    Full Text Available In recent years, within the framework of national as well as international programmes, notable advances and considerable experience have been reached, particularly in minimising of the production of radioactive wastes, conditioning and disposal of short-lived, low and intermediate level waste, vitrification of fission product solutions on an industrial scale and engineered storage of long-lived high level wastes, i.e. vitrified waste and spent nuclear fuel. Based on such results, near-surface repositories have successfully been operated in many countries. In contrast to that, the disposal of high level radioactive waste is still a scientific and technical challenge in many countries using the nuclear power for the electricity generation. Siting, planning and construction of repositories for the high level wastes in geological formations are gradually advancing. The site selection, the evaluation of feasible sites as well as the development of safety cases and performance of site-specific safety assessments are essential in preparing the realization of such a repository. In addition to the scientific-technical areas, issues regarding economical, environmental, ethical and political aspects have been considered increasingly during the last years. Taking differences in the national approaches, practices and the constraints into account, it is to be recognised that future developments and decisions will have to be extended in order to include further important aspects and, finally, to enhance the acceptance and confidence in the safety-related planning work as well as in the proposed radioactive waste management and disposal solutions.

    2002-01-01

    Since its inception at the National Aeronautics and Space Administration (NASA) Ames Research Center in the mid-1970s, many laboratories around the world have used the rat hindlimb unloading model to simulate weightlessness and to study various aspects of musculoskeletal loading. In this model, the hindlimbs of rodents are elevated to produce a 30 degrees head-down tilt, which results in a cephalad fluid shift and avoids weightbearing by the hindquarters. Although several reviews have described scientific results obtained with this model, this is the first review to focus on the technical aspects of hindlimb unloading. This review includes a history of the technique, a brief comparison with spaceflight data, technical details, extension of the model to mice, and other important technical considerations (e.g., housing, room temperature, unloading angle, the potential need for multiple control groups, age, body weight, the use of the forelimb tissues as internal controls, and when to remove animals from experiments). This paper is intended as a reference for researchers, reviewers of manuscripts, and institutional animal care and use committees. Over 800 references, related to the hindlimb unloading model, can be accessed via the electronic version of this article.

    Full Text Available The aim of the research "Body image as a part of active life style" was to explore the meaning of several aspects of physical and psychological self and satisfaction with them. We are interested in the degree of meaning, satisfaction, control and chance for change. The article analyses the relation of 866 women (18-60 years old to their own body and health and to the own ideas and feelings. The monitored women feel considerable discrepancy between the importance of several items related to their body and psyche and between the satisfaction with them. The largest disproportion in the evaluation of importance and satisfaction was discovered at the life without fear, fright and tense (49 %. A big discrepancy was founded also at physical activities and fitness (32 %. The control over body and psyche perceive more than 60 % of the women, spirituality is a little more controlled than corporality. Contentment was evaluated less than control, opportunity and importance. More than 60 % of women showed dissatisfaction with the aspects of body and psyche. We have to learn to know the worth of our self and care of own progress in relation and limits of individual occasions. The satisfaction with the self is a ground of physical and psychological well - being.

  9. Omniclassical Diffusion in Low Aspect Ratio Tokamaks

    International Nuclear Information System (INIS)

    Mynick, H.E.; White, R.B.; Gates, D.A.

    2004-01-01

    Recently reported numerical results for axisymmetric devices with low aspect ratio A found radial transport enhanced over the expected neoclassical value by a factor of 2 to 3. In this paper, we provide an explanation for this enhancement. Transport theory in toroidal devices usually assumes large A, and that the ratio B p /B t of the poloidal to the toroidal magnetic field is small. These assumptions result in transport which, in the low collision limit, is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device one may have B p /B t ∼ 1, and the gyroradius may be larger than the banana excursion. Here, we develop an approximate analytic transport theory valid for devices with arbitrary A. For low A, we find that the enhanced transport, referred to as omniclassical, is a combination of neoclassical and properly generalized classical effects, which become dominant in the low-A, B p /B t ∼ 1 regime. Good agreement of the analytic theory with numerical simulations is obtained

  10. International acceptance of irradiated food. Legal aspects

    International Nuclear Information System (INIS)

    1979-01-01

    The three international organizations competent in the field of irradiation processing for the preservation of food (FAO, WHO, IAEA), convened, at the end of 1977, an Advisory Group to revise and update the recommendations of a similar group which met in early 1972. The Advisory Group considered how national regulations could be harmonized so as to facilitate the international movement of irradiated food. This publication contains the Report of the Advisory Group, which summarizes the considerations of the Group on regulatory control over the irradiation plant and irradiation of foods, and on assurances for comparability of control (international labelling and documentation). Annexes 1 to 6 are included in order to complete the relevant information on the legal aspects of this subject. They include a Draft General Standard for Irradiated Foods, a Draft Code of Practice for the Operation of Radiation Facilities Used for the Treatment of Foods, Recommendations of a Consultation Group on the Legal Aspects of Food Irradiation, a Listing of the Legislation on Food Irradiation Adopted in Member States (1971-1976), and Model Regulations for the Control of and Trade in Irradiated Food

    Full Text Available The study presented here seeks to highlight the interactions between the semantic and verbal aspect or "morphological" in French and Italian. Its starting point is constituted by the confusion existing in the Romance languages for the notion of aspect. In most cases, it concerns the opposition unaccomplished / accomplished that is manifested morphologically, with the presence of the auxiliary in compound forms, with very few references to the couple imperfective / perfective rooted in the meaning of the verb. Our analysis examines the interactions of the most significant and shows that the semantic aspect, although it is not a separate category in the Romance languages, helps to understand phenomena related to the verbal aspectuality.

    Full Text Available The strategic organizational change aims is the change of procedures and systems, organizational structures and responsibilities but especially acquiring new knowledge and skills. Significant authors (Drucker: 1999; Kotter: 1996; Buckingham n Clifton: 2001, supporters of the theory of strategic leadership show an inclination for the idea of optimal management of an organization, which depends on circumstantial factors as place and time, the individual and the context in which it acts. Many experts who studied organizational change saw as possible the future replacement of the current state, desired only after completion of specific phases, in a certain sequence. In this article we will focus our attention on the reduction phase of resistance to change. The research objectives targeted both theoretical aspects consisting in bringing to the forefront the relevant aspects related to organizational change in the current context and practical aspects related to identifying and analyzing the main elements that make it possible or on the contrary act as brakes in way of introduction and implementation of change. To achieve the research objectives, we used the method of direct observation and the questionnaire method supported by the gathering of more information from the organization's documents (Beton Construct SRL and support discussions with the employees. Data processing and analysis revealed that in the organization certain factors exist and manifest that constitute obstacles or inhibit organizational change, namely: the goal of the change is not clear, the rewards of change are not related to the effort needed to make them happen, change determines fear of failure, change is often imposed by coercion, change requires effort and commitment required for employees that think they do not have resources anymore. Summarizing the results of usage for certain methods and techniques to implement change, we can say that the actions of an authoritarian

  15. Ethical aspects of trade subject to risk

    The paper pleads for unrestricted use of the requirement of rational risk comparison. The ethical aspects of the problem are that human beings cannot help expecting certain people to take risks and others to forsake them. Expectation of risk requires an ethical justification. Consideration of justification has of course to originate from the fact that both readiness to accept risk and also the preference system are subject to strong subjective variations. Consequently, intercession has to be made to compare the definition of subjective probability (competitiveness) and a subjective preference matrix as the basis for a rational definition of risk. General liability results first due to the fact that consistency can be expected from each individual in relation to the readiness to accept risk expected of him. According to the requirement for consistency introduced here, a readiness to accept risk may be expected of an individual which is otherwise already accepted. (orig.) [de

    Full Text Available Algal biodiesel production will play a significant role in sustaining future transportation fuel supplies. A large number of researchers around the world are investigating into making this process sustainable by increasing the energy gains and by optimizing resource-utilization efficiencies. Although, research is being pursued aggressively in all aspects of algal biodiesel production from microalgal cell cultivation, cell harvesting, and extraction and transesterification steps to the final product separation and purification, there is a large disparity in the data presented in recent reports making it difficult to assess the real potential of microalgae as a future energy source. This article discusses some of the key issues in energy consumption in the process of algal biodiesel production and identifies the areas for improvement to make this process energy-positive and sustainable.

  18. Aspects with Program Analysis for Security Policies

    DEFF Research Database (Denmark)

    Yang, Fan

    . This dissertation explores the principles of adding challenging security policies to existing systems with great flexibility and modularity. The policies concerned cover both classical access control and explicit information flow policies. We built our solution by combining aspect-oriented programming techniques......Enforcing security policies to IT systems, especially for a mobile distributed system, is challenging. As society becomes more IT-savvy, our expectations about security and privacy evolve. This is usually followed by changes in regulation in the form of standards and legislation. In many cases......, small modification of the security requirement might lead to substantial changes in a number of modules within a large mobile distributed system. Indeed, security is a crosscutting concern which can spread to many business modules within a system, and is difficult to be integrated in a modular way...

    Full Text Available The transmissible venereal tumor is among the main diseases that affect domestic animals of the Canidae family. Abandoned animals are the main transmitters of the disease, which is highly contagious; most of the injuries are commonly found on animals genital organs and faces. This is a tumor without any involvement with an infectious agent, tumor cells are transferred from a sick animal to a healthy animal through natural breeding or direct contact of the lesions with other body parts. The disease has no predisposition for breeding, sex and species, therefore possibly affecting all canids although there are more reports on stray animals.The TVT lesions have cauliflower appearance and may be pedunculated, papillary or multilobulated, with hemorrhagic and crumbly aspect. The tumor can have benign or malignant potential, being the second most frequently commonly reported, wherein according to its potential raise the difficulty of the treatment or not.

    The author proposes a discussion of a new branch of the public law - the nuclear law. The main subject is the radioactive waste. Its production is a decisive problem in the utilization of nuclear energy being one of the discussed questions from the technical, economical, political, social and juridical points of view. Countries have been striving to establish their own policies related to radioactive wastes having always in mind the man and the environmental protection. In this scenario the author developed the investigations trying to discuss juridical and institutional aspects of radioactive wastes on the international level as well as in different countries with the aim to establish the juridical basis of a radioactive wastes policy in Brazil [pt
