    Nuclear technology such as γ-rays, electron beams and ion beams irradiation is widely used in industrial, medical and agricultural fields. The purpose of radiation application is aiming at increasing welfare and quality of our life. Radiation technology applied to medical care is widely known as X-ray diagnosis but the contribution of radiation processing to our daily life is not well known even though it is effectively used in industry and agriculture. The main radiation processing in industry is the modification of polymers, i.e. heat shrinkable tube, radial tire, plastic foam, etc. in a car, heat resistant wire and cable, semiconductor, floppy disk, etc. in a computer, and sterilization of medical devices. In Agriculture, radiation has been used in various fields such as food irradiation, sterile insect technique, mutation breeding, etc. contributing for human being to supply foods and sustainable environment.

    2009-07-01

    This book aims to give a cross section from a wide range of phenomena that, to different degrees, fall under the heading of non-equilibrium phenomenology. The selection is, of course, biased by the interests of the members of the scientific committee and of the FP6 Project 026328 IPB-CNP Reinforcing Experimental Centre for Non-equilibrium Studies with Application in Nano-technologies, Etching of Integrated Circuits and Environmental Research. Some of the papers included here are texts based on selected lectures presented at the Second International Workshop on Non-equilibrium Processes in Plasmas and Environmental Science. However, this volume is not just the proceedings of that conference as it contains a number of papers from authors that did not attend the conference. The goal was to put together a volume that would cover the interests of the project and support further work. It is published in the Institute of Physics journal Journal of Physics: Conference Series to ensure a wide accessibility of the articles. The texts presented here range from in-depth reviews of the current status and past achievements to progress reports of currently developed experimental devices and recently obtained still unpublished results. All papers have been refereed twice, first when speakers were selected based on their reputation and recently published results, and second after the paper was submitted both by the editorial board and individual assigned referees according to the standards of the conference and of the journal. Nevertheless, we still leave the responsibility (and honours) for the contents of the papers to the authors. The papers in this book are review articles that give a summary of the already published work or present the work in progress that will be published in full at a later date (or both). In the introduction to the first volume, in order to show how far reaching, ubiquitous and important non-equilibrium phenomena are, we claimed that ever since the early

    International Nuclear Information System (INIS)

    2007-01-01

    In recent years, the problems of environmental damage and degradation of natural resources have received increasing attention throughout the world. Population growth, higher standards of living, increased urbanization and enhanced industrial activities all contribute to environmental degradation. For example, fossil fuels - including coal. natural gas, petroleum, shale oil and bitumen - are the main primary sources of heat and electrical energy production, and are responsible for a large number and amount of pollutants emitted to the atmosphere via exhaust gases from industry. power stations, residential heating systems and vehicles. All of these fuels are composed of major constituents such as carbon, hydrogen and oxygen, and other components including sulphur and nitrogen compounds and metals. During the combustion process, different pollutants are emitted, such as fly ash (containing diverse trace elements (heavy metals)), SO x (including SO 2 and SO 3 ). NO x (including NO 2 and NO) and volatile organic compounds (VOCs). Air pollution caused by particulate matter and other pollutants not only directly impacts the atmospheric environment but also contaminates water and soil, leading to their degradation. Wet and dry deposition of inorganic pollutants leads to acidification of the environment. These phenomena have a negative impact on human health and on vegetation

    Soil erosion and associated sedimentation are natural processes caused by water, wind and ice. Several of man's activities such as deforestation, overgrazing, changes in land use, and non-sustainable farming practices tend to accelerate soil erosion. Soil erosion and sedimentation cause not only on-site degradation of a non-renewable natural resource, but also off-site problems such as downstream sediment deposition in fields, floodplains and water streams. These problems and concern over the degradation of the landscape by erosion, and their impacts on soil fertility and crop productivity in agricultural land, water pollution, and sedimentation in lakes, reservoirs, and floodplains are well documented. Global estimates of economic damage from soil erosion and sedimentation have also been made. Recent focus on sustainability issues has resulted in increased attention on soil-degradation problems, in particular soil erosion and sedimentation. In view of increasing water scarcity and limited land resources to feed an ever-growing world population, there is an urgent need to obtain reliable quantitative data on the extent and rates of soil erosion worldwide to provide a more comprehensive assessment of the problem and to underpin the selection of effective soil-conservation technologies and sedimentation remediation strategies, including assessment of their economic and environmental impacts. This chapter describes the use of fallout 137 Cs as a tracer for measuring soil erosion and sedimentation, and the potential use of other radionuclides such as 210 Pb, and 7 Be for these studies. It provides an overview of the 137 Cs technique describing key assumptions and requirements, and advantages and limitations of the technique. Also, applications, recent developments, and future trends of the technique are covered. The chapter is completed with an introduction to the handbook and a list of selected references

    2011-01-01

    Modern physics lacks a unitary theory that applies to all four fundamental interactions. This PhD thesis is a proposal for a single, complete, and coherent scheme of mathematically formulated elementary laws of nature. While the first chapter presents the general background, the second chapter addresses the method by which the main result has been developed. The next three chapters rigorously introduce the Elementary Process Theory, its mathematical foundations, and its applications to physics, cosmology and philosophy of mind. The final two chapters discuss the results and present the conclusions. Summarizing, the Elementary Process Theory is a scheme of seven well-formed closed expressions, written in the mathematical language of set matrix theory – a generalization of Zermelo-Fraenkel set theory. In the physical world, these seven expressions can be interpreted as elementary principles governing the universe at supersmall scale. The author critically confronts the theory with Quantum Mechanics and Genera...

    Dwarf galaxies are excellent laboratories of chemical evolution. Many dwarf galaxies have simple star formation histories with very low average star formation rates. These conditions simplify models of chemical evolution and facilitate the identification of sites of nucleosynthesis. Dwarf galaxies also host extremely metal-poor stars, which sample the ejecta of the first generations of supernovae in the universe. This meeting-in-a-meeting, "Stellar Abundances in Dwarf Galasxies," will recognize the importance of dwarf galaxies in learning about the creation and evolution of the elements. Topics include: * the most metal-poor stars * the connection between dwarf galaxies and the Milky Way halo * dwarf galaxies as the paragons of r-process nucleosynthesis * modern techniques in stellar abundance measurements * recent advances in chemical evolution modelingI will give a very brief introduction to set the stage for the meeting.

    The understanding of the decision-making process in the introduction of new vaccines helps establish why vaccines are adopted or not. It also contributes to building a sustainable demand for vaccines in a country. The purpose of the study was to map and analyze the formal decision-making process in relation to the introduction of new vaccines within the context of health policy and health systems and identify the ways of making decisions to introduce new vaccines in Bangladesh. During February-April 2011, a qualitative assessment was made at the national level to evaluate the decision-making process around the adoption of new vaccines in Bangladesh. The study population included: policy-level people, programme heads or associates, and key decision-makers of the Government, private sector, non-governmental organizations, and international agencies at the national level. In total, 13 key informants were purposively selected. Data were collected by interviewing key informants and reviewing documents. Data were analyzed thematically. The findings revealed that the actors from different sectors at the policy level were involved in the decision-making process in the introduction of new vaccines. They included policy-makers from the ministries of health and family welfare, finance, and local government and rural development; academicians; researchers; representatives from professional associations; development partners; and members of different committees on EPI. They contributed to the introduction of new vaccines in their own capacity. The burden of disease, research findings on vaccine-preventable diseases, political issues relating to outbreaks of certain diseases, initiatives of international and local stakeholders, pressure of development partners, the Global Alliance for Vaccines and Immunization (GAVI) support, and financial matters were the key factors in the introduction of new vaccines in Bangladesh. The slow introduction and uptake of new vaccines is a concern

A mass of contradictions and a crucial figure in the history of the British press, Stead was a towering presence in the cultural life of late-Victorian and Edwardian society. In this introduction, we consider Stead as a ‘mass of contradictions’ and offer a few ways in which his prodigious output and activity might be understood.

    The Heavy Ion Laboratory of the Warsaw University is a 'User type' facility, providing heavy ion beams to a number of Polish and foreign research groups and, to limited extent, for its own research programme. In 2006 the Warsaw cyclotron has operated during about 2500 hours of beam on target. 18 experiments, all recommended by the Program Advisory Committee, have been performed by more than one hundred facility users. Their scientific achievements are presented in this Report. This year the publication harvest was slightly smaller as compared to previous years. However, the first Phys. Rev. Letters paper, based completely on the HIL data, should be noticed. The important part of the Laboratory team effort was devoted to educational and science popularization activities, described in details in the following pages of this report. Here, I would like to especially mention the Workshop on Heavy Ion Acceleration and its Application, devoted to physics students of Universities outside Warsaw. The 2006 Workshop was organized for the second time. We do hope, that this workshop will contribute to establishing in Poland more formal recognition for inter-university students and tutors exchange. This, as we hope, will benefit in the Ministry funding of this programme in the future. In 2006 the Laboratory equipment was further developed. The ICARE particle multidetector system was installed on the beam line D and was tested using 16 O beam. Work is in progress on improving its characteristics (signal processing and acquisition) and on expanding possible applications by adding the Time-of-Flight components. The project of a new gamma-ray spectrometer with up to 30 Ge detectors was prepared, discussed and preliminary accepted for realization, when necessary funds are available. In the mean time a new particle detector chamber was tested in coincidence with the OSIRIS II set-up, demonstrating a substantially higher efficiency and lower background in the Coulomb excited gamma

    This chapter introduces the notion and theme of market-based fisheries management. The introduction of market mechanisms to distribute and manage fishing quota has internationally occurred since the 1980s but is increasingly on the political agenda. As privatization and transferability are promoted...... internationally, and by big players, it becomes even more crucial to understand its social and environmental implications. This chapter looks at the broader lines in the fisheries research and discusses the diverging views on market-based fisheries management. On one side market mechanisms are promoted...... for efficiency and fleet adaptation, and on the other, quota markets are accused of causing concentration and disturbing social relations....

    deduced for irreversible processes (C. Jarzynski). The survey of non-equilibrium steady states in statistical mechanics of classical and quantum systems employs heat bath models and the random matrix theory input. The quantum heat bath analysis and derivation of fluctuation-dissipation theorems is performed by means of the influence functional technique adopted to solve quantum master equations (D. Kusnezov). Chapter II deals with an issue of relaxation and its dynamical theory in both classical and quantum contexts. Pollicott-Ruelle resonance background for the exponential decay scenario is discussed for irreversible processes of diffusion in the Lorentz gas and multibaker models (P. Gaspard). The Pollicott-Ruelle theory reappears as a major inspiration in the survey of the behaviour of ensembles of chaotic systems, with a focus on model systems for which no rigorous results concerning the exponential decay of correlations in time is available (S. Fishman). The observation, that non-equilibrium transport processes in simple classical chaotic systems can be described in terms of fractal structures developing in the system phase space, links their formation and properties with the entropy production in the course of diffusion processes displaying a low dimensional deterministic (chaotic) origin (J. R. Dorfman). Chapter III offers an introduction to the theory of dynamical semigroups. Asymptotic properties of Markov operators and Markov semigroups acting in the set of probability densities (statistical ensemble notion is implicit) are analyzed. Ergodicity, mixing, strong (complete) mixing and sweeping are discussed in the familiar setting of "noise, chaos and fractals" (R. Rudnicki). The next step comprises a passage to quantum dynamical semigroups and completely positive dynamical maps, with an ultimate goal to introduce a consistent framework for the analysis of irreversible phenomena in open quantum systems, where dissipation and decoherence are crucial concepts (R

    Another aspect that was addressed to a certain extent last night was the Non-Proliferation Treaty. Don't we believe the people who signed the Treaty? Yes, we do. However, even in the Treaty itself there are safeguards to insure the people who have signed the Treaty are abiding by its provisions. There are also a large number of countries that have not signed the Non-Proliferation Treaty. And some of these countries that have not signed are in areas of the world where neighboring countries are not very friendly with each other, and so the fact of non-signature and the world situation in that area makes it one of concern. The NPT also obligates nuclear weapons states to not discriminate against the non-nuclear weapons state to the extent possible. That is one of the reasons that, when we come up with a policy relating to the use of HEU in research reactors, we are attempting to apply this policy equally throughout the world. I guess I should say of those countries that have not signed the NPT, if you ask them why they have not signed, the primary reasons that you get is because the NPT discriminates against non-nuclear weapons states. The US has attempted, with the Special Session on Disarmament recently and the initiatives there, as Dick Lewis pointed out, to try to make an easy as possible the changes in the operation of research reactors that are being more or less pushed by the US. I guess I should say that the US is not alone in pushing for this type of policy and that there are many other countries in the world who also agree that this particular program should continue

    The concept that neural information is encoded in the firing rate of neurons has been the dominant paradigm in neurobiology for many years. This paradigm has also been adopted by the theory of artificial neural networks. Recent physiological experiments demonstrate, however, that in many parts of the nervous system, neural code is founded on the timing of individual action potentials. This finding has given rise to the emergence of a new class of neural models, called spiking neural networks. In this paper we summarize basic properties of spiking neurons and spiking networks. Our focus is, specifically, on models of spike-based information coding, synaptic plasticity and learning. We also survey real-life applications of spiking models. The paper is meant to be an introduction to spiking neural networks for scientists from various disciplines interested in spike-based neural processing.

    Full Text Available The city as a mosaic of anarchic diversity and messy contradictions has always been a rich source of inspiration for practitioners of creative arts. Writers, painters, planners, photographers, performers have deemed the city as the loci of their desire, conflict, passion and memory to chart the minutes of quotidian life in various intricate forms and configurations. “The city came into being when a surplus of food allowed a diversity of tasks”, Lehan asserts in his introduction to The City in Literature. “Diversity is a key to urban beginnings and continuities, and diversity is also the snake in the urban garden, challenging systems of order and encouraging disorder and chaos” (8. As an eclectic site of cultural friction and contamination that simultaneously oscillates between polarities of belonging and non-belonging, order and chaos, the city unlocks myriad windows to the chroniclers of urban realities. The cities in their perpetual making and dismantling, bear an impression of what Amit Chaudhuri terms in a recent talk as the “unfinished-ness” in the context of modern cities[1]. The “unfinished” is a slippery term as Chaudhuri explains, while it may suggest the Modernist artists’ proclivity towards dereliction, ruin or fragmentation in metropolitan landscape, it also speaks of the “half-made”[2], the backward, or the liminal spaces within an urban conurbation. However, this “unfinished-ness” or the fact that “cities are not finished products” as Chaudhuri posits, is also indicative of their “radical openness” and their inexhaustible potentials for reinventing themselves.

    Full Text Available The introduction to the monographic section Italy-Ireland: Cultural Inter-Relations, gives a brief account of how this part of the journal tries to fill a gap in transcultural studies by investigating the hitherto relatively underexplored relationship of Ireland with Italy. The editors argue that the topic deserves special attention because throughout the centuries, owing to a shared religion and Ireland’s colonial and postcolonial status, a special relationship was established. Without neglecting the many contributions published on this topic over the past thirty years, the papers collected in this first issue of SIJIS offer an overall view of the relations between Italy and Ireland from the Middle Ages to the present day demonstrating this special relationship. The opening essay, drawing an ample and interdisciplinary panorama of the representations of Ireland in Italy over the centuries, and  the concluding one, introducing new issues and suggestions for further investigations, frame seven papers organized thematically in subsections.  The translation studies section highlights some specific problems presented to the translator because of the Irish nature of the translated texts. Exploration of the links between some major figures and Italy opens up new perspectives even regarding much studied figures such as Joyce while  the time-honoured comparative method of studying influences yields ground-breaking insights as in the study of links between Commedia dell’Arte and Clarke or Mahon and Pasolini. Representations of Italy and  the presence of Italian settings and characters acquire  a specific Irish edge in the writings of Synge, Lady Morgan and Edward Maturin especially when both countries were still in search  of their identities.

    Early Nimbus satellites collected both visible and infrared observations of the Earth at high resolution. Nimbus I operated in September, 1964. Nimbus II operated from April to November 1966 and Nimbus III operated from May 1969 to November 1969. We will discuss our procedures to recover this data into a modern digital archive useful for scientific analysis. The Advanced Videocon Camera System data was transmitted as an analog signal proportional to the brightness detected by a video camera. This was archived on black and white film. At NSIDC we are scanning and digitizing the film images using equipment derived from the motion picture industry. The High Resolution Infrared Radiance data was originally recorded in 36 bit words on 7 track digital tapes. The HRIR data were recently recovered from the tapes and TAP (tape file format from 1966) files were placed in EOSDIS archives for online access. The most interesting parts of the recovery project were the additional processing required to rectify and navigate the raw digital files. One of the artifacts we needed to identify and remove were fiducial marks representing latitude and longitude lines added to the film for users in the 1960's. The IR data recording inserted an artificial random jitter in the alignment of individual scan lines. We will describe our procedures to navigate, remap, detect noise and remove artifacts in the data. Beyond cleaning up the HRIR swath data or the AVCS picture data, we are remapping the data into standard grids for comparisons in time. A first run of all the Nimbus 2 HRIR data into EASE grids in NetCDF format has been completed. This turned up interesting problems of overlaps and missing data issues. Some of these processes require extensive computer resources and we have established methods for using the 'Elastic Compute Cloud' facility at Amazon.com to run the many processes in parallel. In addition we have set up procedures at the University of Colorado to monitor the ongoing

    The literature study assesses, in the form of expert analysis, geological processes and events for a 1200 km 2 -area of northern Switzerland, with regard to repositories for medium- and high-active waste (depth 100 to 600 m and 600 to 2500 m, respectively) over the next 10 6 years. The area, which comprises parts of the Tabular Jura, the folded Jura and the Molasse Basin, the latter two being parts of the Alpine Orogene, has undergone a non-uniform geologic development since the Oligocene. Within the next 10 4 to 10 5 years a maximum earthquake intensity of VIII-IX (MSK-scale) has been predicted. After this period, particularly in the southern and eastern parts of the area, glaciations will probably occur, with associated erosion of possibly 200 to 300 m. Fluvial erosion as a reponse to an uplift could reach similar values after 10 5 to 10 6 years; however, there are no data on the recent relative vertical crustal movements of the area. The risk of a meteorite impact is considered small as compared to that of these factors. Seismic activity and the position and extent of faults are so poorly known within the area that the faulting probability cannot be derived at present. Flooding by the sea, intrusion of magma, diapirism, metamorphism and volcanic eruptions are not considered to be risk factors for final repositories in northern Switzerland. For the shallow-type repositories, the risk of denudation and landslides have to be judged when locality-bound projects have been proposed. (Auth.)

    Since the Atoms for Peace program in 1950s, peaceful applications of nuclear technology has been at the forefront of the development of many countries. In Malaysia, the development of nuclear technology began in earnest with the setting-up of Malaysian Nuclear Agency (Nuclear Malaysia) in 1972, then known as CRANE. More than thirty years later, today, the technology has gained footing and made impact to the development of the country. Her role in regional and international scenes in nuclear-related matters and nuclear technology was noticed and being given due attention. It is time to take stock of this development and assess its impact upon which further developments can be planned and strategized. That was the genesis of this study. This chapter presents a review of the status and development of nuclear technology globally and in Malaysia to provide a background for the report and the study. This is followed by an introduction to the study: its objectives, scope, methods of research, total population, sampling frame, selection procedures, target groups and data analysis. The chapter concludes with a guide to the organization of this report. The study was conducted with the aim of evaluating the impact and contribution of nuclear technology to socio-economic development of the country. It is also expected to identify issues and challenges faced by users of this technology. Even though the applications of nuclear technology encompass diverse human endeavors, this study focuses only in industrial, medical and agriculture sectors. The applications of nuclear technology in both public agencies and private companies in those sectors are considered. This is the first time such a study is being undertaken in Malaysia, and as a starting point, the three year period spanning 2006-2008 are taken as the time frame for discerning trends of nuclear technology development in the country. This study was also in an indirect sense motivated by similar studies conducted in the USA

Encapsulation, a process to entrap active agents into particles, is an important way to meet these demands by delivering food ingredients at the right time and place. For example, this technology may allow taste and aroma differentiation, mask bad tasting or bad smelling components, stabilize food ingredients and/or increase their bioavailability. Encapsulation may also be used to immobilize cells or enzymes in the production of food materials or products, as in fermentation or metabolite production.

In 2005 the Warsaw cyclotron operated for close to 3000 hours of beam on target. 20 experiments, all recommended by the Program Advisory Committee, were performed by more than one hundred facility users. Their scientific achievements are presented in this Report. Here I would like to mention some highlights of the scientific projects with heavy-ion beams delivered by HIL cyclotron. Search for chirality in medium mass nuclei using OSIRIS-II set-up resulted in vivid discussion among nuclear spectroscopists, both theorists and experimentalists. Studies of the quasi-elastic barrier distributions revealed interesting phenomena, not yet fully explainable. Giant Dipole Resonance project with JANOSIK system yielded many new results. Coulomb Excitation investigation of shape coexistence in nuclei was progressing, providing data complementary to those from radioactive beams from CERN and GANIL. Also interesting results concerning optical-model potential in light nuclei interactions were obtained within Warsaw-Krakow-Kiev collaboration. Besides pure nuclear physics the cyclotron delivered beams for projects in solid-state physics, most notably connected to detector development as well as for biological studies. HIL remained an interdisciplinary user facility, keeping high profile of its scientific output, as can be judged from the list of publications contained in Part D of this Report. At the end of 2005 our experimental equipment started to be substantially enlarged. Thanks to the collaboration with the CNRS centre IRES in Strasbourg their excellent charged particle multidetector set-up ICARE was installed on the 'last-free' beam line of the Warsaw Cyclotron. After the well organized transportation and mechanical mounting by an experts team from IRES in collaboration

    This chapter illustrates the role of JAEA in conducting Research and Development on deep geological disposal of nuclear waste, on the reliability of the disposal technology and on safety assessment methods. Within this frame, the present study seeks a better understanding of the influence of the in-situ conditions on the sampling process through the analysis of sample damage. The correlation between sample damage and in-situ stress conditions provides a tool for correction of the laboratory test results and for predicting stresses and in-situ mechanical properties of the Toki granite at the MIU Construction Site (Mizunami, Gifu Pref., Japan). This study of the literature, sample conditions, available laboratory results and numerical models will lead to the proposal of a statistical method based on fractal geometry for quantifying cracking and fracturing in brittle rocks and describing its dependence on the level of stress.

    In 1972, Nuclear Fuels Divisions of Sumitomo and Furukawa Electric Industries merged and became a subsidiary of Sumitomo and Furukawa Industries which is now called Nuclear Fuel Industries, Ltd. We design and manufacture various kinds of nuclear fuels. As for research reactor fuel, we began our development activities in 1956. Since then we have spent over 2 million dollars for development of nuclear fuels and plant facilities including complete manufacturing and testing capabilities. Now we are the only supplier of the research reactor fuel in Japan. Our fabrication process starts with the melting, alloying, and casting of U-Al. The uranium billets are prepared by foreign fabricators. The uranium content varies from 13 to 22 wt % according to the purchaser's specifications. In making fuel plates, the picture frame method is applied. In this case, our original procedure is sufficiently effective in avoiding dogboning. The plates are finished by hot and cold roll milling and inspected dimensionally, metallurgically, and mechanically, and at the same time the blister test and X-ray radiographic tests are performed. Fuel elements are assembled by rolling flat or curved plates into side plate grooves and end-fit welding. Finished elements are tested dimensionally and hydraulically. Nominal losses during operation are less than 1% of the uranium metal. Our present capacity licensed by the Japanese Government is approximately 950 fuel elements a year. About 35 employees including engineers are engaged in development and manufacturing of fuels. Owing to the small limited demand of the research reactor fuels in Japan during the past 20 years (mostly in last 10 years), we processed only about 350 kg of highly enriched uranium and supplied approximately 1000 fuel elements to JAERI, Kyoto University, and others, and we have been suffering red-ink balance of budget every year

    Conviviality''. However, it was the academic menu of ICGC-1987 that took precedence over anything else. The Scientific Organizing Committee, consisting of Vishveshwara (Vishu, if your tongue is not up to pronouncing the full name) as the Chairman, and Ashtekar, Barrow, Bertotti, Brill, Carr, Hartle, Hu, Iyer, MacCallum, Narlikar, Novikov, Penrose, and Sciama reflected a nice international mix as well as a mix of active branches of Gravitation and Cosmology. Later meetings The original intention of meeting every four years in some part of India was honoured by the community, and accordingly, the ICGC met in Ahmedabad (1991), Pune (1995), Kharagpur (2000), Cochin (2004), and Pune (2007) before reconvening in Goa in 2011. These meetings were more modestly planned, and instead of trying to cover many fields, each meeting was limited to some specialized topics. Thus, the Kharagpur meeting had highlighted gravitational waves, while the Pune (1995) meeting had emphasized the Raychaudhuri equation and the singularity theorems. These conferences did help to put India firmly on the map of GR and Cosmology, to the extent that the GR-15 was held successfully in Pune with Naresh Dadhich from IUCAA playing the main coordinator's role. It has been a pleasure to see young blood being attracted to these areas of research. Two major developments are on the horizon at the time of writing this piece. The LIGO is planning to set up an extra detector of gravitational waves in India with local help, both in hardware and software. Likewise, steps are being taken for India to join the TMT mega-telescope project as an international partner. These heartening developments help us to bear the loss of old doyens like, V V Narlikar, P C Vaidya, and A K Raychaudhuri. Though 'small is beautiful' is a truism, the decision was taken to return to Goa with a wider and richer academic menu to recall and celebrate the first ICGC. This is how we all find ourselves in Goa and its pleasant surroundings. As they say

    It would be hard to argue against the fact that Integrated Computational Materials Engineering (ICME) is a fast growing discipline within material science and engineering. A quick scan of the proceedings from conferences such as Aeromat, Material Science and Technology, and the TMS Annual Meeting clearly shows it. What began a few years ago as one symposium has grown into multiple ICME related symposia at each of these conferences. As encouraging as the number of symposia being offered is the attendance at the symposia. For example, one of the ICME symposia at MS&T 10, the symposium in which this book is based, had five sessions which culminated in a panel discussion that was standing room only. In addition to the large, annual materials science and engineering conferences, smaller 1 to 2-day conferences/workshops sponsored by government agencies (e.g. AFRL and NIST) on specific aspects of ICME and by universities promoting their ICME work are regularly offered. And arguably the most significant news with regards to ICME and conferences is the July 2011 First World Congress on ICME. This five day TMS sponsored conference, specifically focused on ICME with an international advisory board of ICME leaders, shows how far ICME has spread across the globe. Evidence for the growth of ICME can also be found in Academia. The University Materials Council (UMC) is composed of department heads for material science and engineering from major U.S. and Canadian universities. Meeting twice a year to share best practices in order to strengthen both the engineering content [1] and the educational process, the UMC s agenda for their Spring 2010 meeting was dedicated to ICME [2]. This meeting was held in response to the growing awareness that the universities play a major role in the success of ICME and therefore need to develop ICME curriculum in order to meet that need. To aid educators in the development of ICME courses, NSF is funding a "Summer School" on ICME to be held at the

  8. Inverse scattering and GPR data processing: an Introduction

    Inverse scattering and GPR data processing: an Introduction Raffaele Persico This abstract is meant to propose a brief overview of the book "Introduction to Ground Penetrating Radar: Inverse scattering and data processing", edited by Wiley Press (ISBN 9781118305003). The reason why I propose this contribution is the fact that, in spite of the large relevant literature, to the best of my knowledge it is not very common to find a text entirely devoted to the physical-mathematical aspects (a part of them, of course) of GPR data processing. Also due to this, probably a sort of gap between the GPR practice and the underlying theory has been created, and indeed we can meet practitioners convinced that the quality of the achieved results is indefinitely improvable by making narrower the spatial step of the data, or that it is desirable to have extremely directive antennas because this would improve the resolution. In order to provide a work hopefully able to address these and other aspects and hopefully able to give a contribution to the correction of these imprecise beliefs, a dealing from the beginning has been proposed, i.e. a sequential, relatively plane, and as much as possible self consistent, dealing starting from the Maxwell's equations and reaching the most commonly exploited migration formulas and linear inversion algorithms, both within a 2D and a 3D framework. This follows the didactic aim to provide to the reader an insight about what can be reasonably achieved and what should be reasonably done in the field and during the processing phase in order to achieve satisfying results. In particular, the reader will be hopefully made aware not only of the mathematical passages, but also of the involved approximations, the needed assumptions and the physical limits of the final algorithms. The results have been also back-upped with numerical exercises and with some experimental tests, all of which conceived on purpose for this text, and some questions with the

    Sigmund Freud's thesis was that there is a censorship during waking that prevents memory of events, drives, wishes, and feelings from entering the consciousness because they would induce anxiety due to their emotional or ethical unacceptability. During dreaming, because the efficiency of censorship is decreased, latent thought contents can, after dream-work involving condensation and displacement, enter the dreamer's consciousness under the figurative form of manifest content. The quasi-closed dogma of psychoanalytic theory as related to unconscious processes is beginning to find neurobiological confirmation during waking. Indeed, there are active processes that suppress (repress) unwanted memories from entering consciousness. In contrast, it is more difficult to find neurobiological evidence supporting an organized dream-work that would induce meaningful symbolic content, since dream mentation most often only shows psychotic-like activities.

    1994-01-01

    For about half a century, two classes of stochastic processes-Gaussian processes and processes with independent increments-have played an important role in the development of stochastic analysis and its applications. During the last decade, a third class-branching measure-valued (BMV) processes-has also been the subject of much research. A common feature of all three classes is that their finite-dimensional distributions are infinitely divisible, allowing the use of the powerful analytic tool of Laplace (or Fourier) transforms. All three classes, in an infinite-dimensional setting, provide means for study of physical systems with infinitely many degrees of freedom. This is the first monograph devoted to the theory of BMV processes. Dynkin first constructs a large class of BMV processes, called superprocesses, by passing to the limit from branching particle systems. Then he proves that, under certain restrictions, a general BMV process is a superprocess. A special chapter is devoted to the connections between ...

    Model checkers find failures in software by exploring every possible execution schedule. Java PathFinder (JPF), a Java model checker, has been extended recently to cover networked applications by caching data transferred in a communication channel. A target process is executed by JPF, whereas its peer process runs on a regular virtual machine outside. However, non-deterministic target programs may produce different output data in each schedule, causing the cache to restart the peer process to handle the different set of data. Virtualization tools could help us restore previous states of peers, eliminating peer restart. This paper proposes the application of virtualization technology to networked model checking, concentrating on JPF.

    The development of new extraction processes to produce titanium in powder form leads Powder Metallurgy to an advantage position among the manufacturing processes for titanium. The cost reduction of base material, coupled with the economy of the powder metallurgy processes, give titanium industry the chance to diversify its products, which could lead to production volumes able to stabilise the price of the metal. This work reviews some of the Powder Metallurgy techniques for the manufacturing of titanium parts, and describes the two typical approaches for titanium manufacturing: Blending Elemental and Prealloyed Powders. Among others, conventional pressing and sintering are described, which are compared with cold and hot isostatic pressing techniques. Real and potential applications are described. (Author) 71 refs.

    2013-12-16

    Statistical process control is a well-established and respected method which provides a general purpose, and consistent framework for monitoring and improving the quality of a process. It is routinely used in many industries where the quality of final products is critical and is often required in clinical diagnostic laboratories [1,2]. To date, the methodology has been little utilised in research proteomics. It has been shown to be capable of delivering quantitative QC procedures for qualitative clinical assays [3] making it an ideal methodology to apply to this area of biological research. To introduce statistical process control as an objective strategy for quality control and show how it could be used to benefit proteomics researchers and enhance the quality of the results they generate. We demonstrate that rules which provide basic quality control are easy to derive and implement and could have a major impact on data quality for many studies. Statistical process control is a powerful tool for investigating and improving proteomics research work-flows. The process of characterising measurement systems and defining control rules forces the exploration of key questions that can lead to significant improvements in performance. This work asserts that QC is essential to proteomics discovery experiments. Every experimenter must know the current capabilities of their measurement system and have an objective means for tracking and ensuring that performance. Proteomic analysis work-flows are complicated and multi-variate. QC is critical for clinical chemistry measurements and huge strides have been made in ensuring the quality and validity of results in clinical biochemistry labs. This work introduces some of these QC concepts and works to bridge their use from single analyte QC to applications in multi-analyte systems.

  20. Introduction to the structures and processes of subduction zones

    2017-09-01

    Subduction zones have been the focus of many studies since the advent of plate tectonics in 1960s. Workings within subduction zones beneath volcanic arcs have been of particular interest because they prime the source of arc magmas. The results from magmatic products have been used to decipher the structures and processes of subduction zones. In doing so, many progresses have been made on modern oceanic subduction zones, but less progresses on ancient oceanic subduction zones. On the other hand, continental subduction zones have been studied since findings of coesite in metamorphic rocks of supracrustal origin in 1980s. It turns out that high-pressure to ultrahigh-pressure metamorphic rocks in collisional orogens provide a direct target to investigate the tectonism of subduction zones, whereas oceanic and continental arc volcanic rocks in accretionary orogens provide an indirect target to investigate the geochemistry of subduction zones. Nevertheless, metamorphic dehydration and partial melting at high-pressure to ultrahigh-pressure conditions are tectonically applicable to subduction zone processes at forearc to subarc depths, and crustal metasomatism is the physicochemical mechanism for geochemical transfer from the slab to the mantle in subduction channels. Taken together, these provide us with an excellent opportunity to find how the metamorphic, metasomatic and magmatic products are a function of the structures and processes in both oceanic and continental subduction zones. Because of the change in the thermal structures of subduction zones, different styles of metamorphism, metasomatism and magmatism are produced at convergent plate margins. In addition, juvenile and ancient crustal rocks have often suffered reworking in episodes independent of either accretionary or collisional orogeny, leading to continental rifting metamorphism and thus rifting orogeny for mountain building in intracontinental settings. This brings complexity to distinguish the syn

  2. An introduction to the irradiation processing of foods

    1991-01-01

    The food industry has used a variety of methods over the years to preserve or extend the shelf life of food. These have included cooking, packaging, smoking, chilling, freezing, dehydrating and using chemical additives. More recently, ionising radiation has been used to extend the storage life of foods. More research has been focussed on the effects of irradiation on foods than has been directed at any other form of food processing. This research has spanned 40 years and has been carried out in many countries. Food irradiation can be used to: (a) inhibit the sprouting of vegetables; (b) delay the ripening of fruits; (c) kill insect pests in fruit, grains or spices; (d) reduce or eliminate food spoilage organisms; (e) reduce food poisoning bacteria on some meats and sea food products. This chapter includes sections on the historical background; general aspects of radiation; scientific, technological, microbiological and toxicological aspects of food irradiation; nutritional aspects of food irradiation; consumer attitudes; current status and legislation; labelling. It concludes that the relatively new process of preserving food by irradiation compliments rather than competes with the presently available traditional methods. (author)

    Electron Backscatter Diffraction (EBSD) provides a useful means for characterizing microstructure. However, it can be difficult to obtain index-able diffraction patterns from some samples. This can lead to noisy maps reconstructed from the scan data. Various post-processing methodologies have been developed to improve the scan data generally based on correlating non-indexed or mis-indexed points with the orientations obtained at neighboring points in the scan grid. Two new approaches are introduced (1) a re-scanning approach using local pattern averaging and (2) using the multiple solutions obtained by the triplet indexing method. These methodologies are applied to samples with noise introduced into the patterns artificially and by the operational settings of the EBSD camera. They are also applied to a heavily deformed and a fine-grained sample. In all cases, both techniques provide an improvement in the resulting scan data, the local pattern averaging providing the most improvement of the two. However, the local pattern averaging is most helpful when the noise in the patterns is due to the camera operating conditions as opposed to inherent challenges in the sample itself. A byproduct of this study was insight into the validity of various indexing success rate metrics. A metric based given by the fraction of points with CI values greater than some tolerance value (0.1 in this case) was confirmed to provide an accurate assessment of the indexing success rate. - Highlights: • Re-indexing of saved EBSD patterns after neighbor pattern averaging can provide significant improvements on the indexing success rate particularly with noisy patterns. • Neighbor pattern averaging is most effective on patterns where noise is introduced by the camera operating conditions as opposed to inherent challenges presented by the sample itself. • Confidence Index based metrics are confirmed to generally provide accurate estimates of the indexing success rate albeit increasingly

    Equity and social inclusion for vulnerable groups in policy development processes and resulting documents remain a challenge globally. Most often, the marginalization of vulnerable groups is overlooked in both the planning and practice of health service delivery. Such marginalization may occur because authorities deem the targeting of those who already have better access to healthcare a cheaper and easier way to achieve short-term health gains. The Government of Malawi wishes to achieve an equitable and inclusive HIV and AIDS Policy. The aim of this study is to assess the extent to which the Malawi Policy review process addressed regional and international health priorities of equity and social inclusion for vulnerable groups in the policy content and policy revision process. This research design comprised two phases. First, the content of the Malawi HIV and AIDS Policy was assessed using EquiFrame regarding its coverage of 21 Core Concepts of human rights and inclusion of 12 Vulnerable Groups. Second, the engagement of vulnerable groups in the policy process was assessed using the EquIPP matrix. For the latter, 10 interviews were conducted with a purposive sample of representatives of public sector, civil society organizations and development partners who participated in the policy revision process. Data was also collected from documented information of the policy processes. Our analyses indicated that the Malawi HIV and AIDS Policy had a relatively high coverage of Core Concepts of human rights and Vulnerable Groups; although with some notable omissions. The analyses also found that reasonable steps were taken to engage and promote participation of vulnerable groups in the planning, development, implementation, monitoring and evaluation processes of the HIV and AIDS Policy, although again, with some notable exceptions. This is the first study to use both EquiFrame and EquIPP as complimentary tools to assess the content and process of policy. While the findings

    To identify the age of introduction of ultra-processed food and its associated factors among preschool children. Cross-sectional study carried out from March to June 2014 with 359 preschool children aged 17 to 63 months attending day-care centers. Time until ultra-processed food introduction (outcome variable) was described by the Kaplan-Meier analysis, and the log-rank test was used to compare the survival functions of independent variables. Factors associated with ultra-processed food introduction were investigated using the multivariate Cox proportional hazards model. The results were shown as hazard ratios with their respective 95% confidence intervals. The median time until ultra-processed food introduction was six months. Between the 3rd and 6th months, there is a significant increase in the probability of introducing ultra-processed food in the children's diet; and while the probability in the 3rd month varies from 0.15 to 0.25, at six months the variation ranges from 0.6 to 1.0. The final Cox proportional hazards model showed that unplanned pregnancy (1.32 [1.05-1.65]), absence of prenatal care (2.50 [1.02-6.16]), and income >2 minimum wages (1, 50 [1.09-2.06]) were independent risk factors for the introduction of ultra-processed food. Up to the 6th month of life, approximately 75% of preschool children had received one or more ultra-processed food in their diet. In addition, it was observed that the poorest families, as well as unfavorable prenatal factors, were associated with early introduction of ultra-processed food. Copyright © 2017.

    Full Text Available This study investigated the effects of felling season on the discoloration of rubberwood sawn timber during conventional kiln drying. The samples were collected throughout the year 2015 to monitor the variation of free sugars and starch content in the rubberwood logs. Two batches of logs, one from the rainy season and the other from the dry season, were felled and sawn for experimentation. The findings showed that discoloration was more prominent in sawn timber obtained from logs felled during the dry season. The amount of free sugars and starch in the logs had a strong influence on the extent of discoloration in the rubberwood sawn timber during the kiln drying process. A higher amount of free sugars and starch in the logs felled during the dry season increased the incidence of blue stain on these logs. The results of this study conclusively showed that discoloration in rubberwood can be minimized by the choice of log felling season and the use of an appropriate drying technique, which will inevitably improve the aesthetic appeal of the wood.

    Background The secondary use of health data for research raises complex questions of privacy and governance. Such questions are ill-suited to opinion polling where citizens must choose quickly between multiple-choice answers based on little information. Objective The aim of this project was to extend knowledge about what control informed citizens would seek over the use of health records for research after participating in a deliberative process using citizens’ juries. Methods Two 3-day citizens’ juries, of 17 citizens each, were convened to reflect UK national demographics from 355 eligible applicants. Each jury addressed the mission “To what extent should patients control access to patient records for secondary use?” Jurors heard from and questioned 5 expert witnesses (chosen either to inform the jury, or to argue for and against the secondary use of data), interspersed with structured opportunities to deliberate among themselves, including discussion and role-play. Jurors voted on a series of questions associated with the jury mission, giving their rationale. Individual views were polled using questionnaires at the beginning and at end of the process. Results At the end of the process, 33 out of 34 jurors voted in support of the secondary use of data for research, with 24 wanting individuals to be able to opt out, 6 favoring opt in, and 3 voting that all records should be available without any consent process. When considering who should get access to data, both juries had very similar rationales. Both thought that public benefit was a key justification for access. Jury 1 was more strongly supportive of sharing patient records for public benefit, whereas jury 2 was more cautious and sought to give patients more control. Many jurors changed their opinion about who should get access to health records: 17 people became more willing to support wider information sharing of health data for public benefit, whereas 2 moved toward more patient control over

    Gupta, Munish; Kaplan, Heather C

    2017-09-01

    Quality improvement (QI) is based on measuring performance over time, and variation in data measured over time must be understood to guide change and make optimal improvements. Common cause variation is natural variation owing to factors inherent to any process; special cause variation is unnatural variation owing to external factors. Statistical process control methods, and particularly control charts, are robust tools for understanding data over time and identifying common and special cause variation. This review provides a practical introduction to the use of control charts in health care QI, with a focus on neonatology. Copyright © 2017 Elsevier Inc. All rights reserved.

    2016-01-01

    BPMN (Business Process Model and Notation) is the established standard for business process modeling. Only a few years after its first publication, it has gained widespread adoption in practice. All important modeling tools support BPMN diagramming. It is possible to create business-oriented diagrams, but also technical models for process execution in business process management systems (BPMS). This book provides a stepwise introduction to BPMN, using many examples close to practice. Starting with the basic elements for modeling sequence flow, all BPMN 2.0 diagrams are presented and discussed in detail. You will gain a profound understanding of the complete notation, and you will be able to make correct use of the different language elements. In the second edition, a collection of useful modeling patterns has been added. These patterns provide best-practice solutions for typical problems arising in the practice of process modeling.

    2015-06-20

    Health policy analysis is important for all health policies especially in fields with ever changing evidence-based interventions such as HIV prevention. However, there are few published reports of health policy analysis in sub-Saharan Africa in this field. This study explored the policy process of the introduction of male circumcision (MC) for HIV prevention in Uganda in order to inform the development processes of similar health policies. Desk review of relevant documents was conducted between March and May 2012. Thematic analysis was used to analyse the data. Conceptual frameworks that demonstrate the interrelationship within the policy development processes and influence of actors in the policy development processes guided the analysis. Following the introduction of MC on the national policy agenda in 2007, negotiation and policy formulation preceded its communication and implementation. Policy proponents included academic researchers in the early 2000s and development partners around 2007. Favourable contextual factors that supported the development of the policy included the rising HIV prevalence, adoption of MC for HIV prevention in other sub-Saharan African countries, and expertise on MC. Additionally, the networking capability of proponents facilitated the change in position of non-supportive or neutral actors. Non-supportive and neutral actors in the initial stages of the policy development process included the Ministry of Health, traditional and Muslim leaders, and the Republican President. Using political authority, legitimacy, and charisma, actors who opposed the policy tried to block the policy development process. Researchers' initial disregard of the Ministry of Health in the research process of MC and the missing civil society advocacy arm contributed to delays in the policy development process. This study underscores the importance of securing top political leadership as well as key implementing partners' support in policy development processes

    Full Text Available Background: Patients who had received surgical services at Bellin Hospital reported anxiety with the surgical flow. This study tested the hypothesis that the introduction of a surgical navigator, someone who guided the patient and their accompanying others throughout the surgical process, would improve patient satisfaction. Methods: Ambulatory surgical patients were randomized to control and study groups. The study group patients were assigned a surgical navigator. Prior to discharge from the hospital, patients were asked to complete a patient satisfaction survey. Results: The study group had significantly higher mean scores (P value ≤ 0.026, top box scores (P value ≤ 0.021, and positive comments. Conclusion: The addition of a surgical navigator to the perioperative process significantly enhanced patient satisfaction in ambulatory surgical patients.

    Goswami, G.L.

    1983-01-01

    Weld quality monitoring, as it stands today, is primarily done by X-ray radiography and ultrasonic testing which is applied after welding is complete. Acoustic Emission Technique (AET) also presents a possible substitute for weld quality monitoring which can be used during welding. Acoustic signals are generated during welding and the sound waves of weld defects are picked up by using AE sensors. With the introduction of sophisticated instrumentation in AET, it is possible to carry out the test even in noisy shop floor environments. Large number of reports on the subject of acoustic emission in recent years is a clear indication that it is gaining importance in welding industry. The present day status of the acoustic emission technology as an on-line weld quality monitoring technique has been reviewed. This report discusses the technique and system along with the acoustic emission parameters important for weld quality analysis. This also deals with the application of this technique in different welding processes like TIG, resistance, electro slag and submerged arc. It has been reported that monitoring of emission during welding can detect crack formation, crack growth and lack of fusion precisely. Static defects like porosity and inclusion do not generate very strong acoustic signals and are therefore difficult to intercept, but, however, lately they have detected successfully. (author)

    2013-07-01

    This article aims to make an introduction to the use of Functional Resonance Analysis Method (FRAM) on the effectiveness assessment of a specific radiopharmaceutical dispatching process. The main purpose was to provide a didactic view of the method application to further in-depth analysis. The investigation also provided a relevant body of knowledge of radiopharmaceuticals dispatches processes. This work uses the term 'effectiveness assessment' instead of 'risk assessment' due to the broader meaning the former provide. The radiopharmaceutical dispatching process is the final task of a dynamic system designed to attend several medical facilities. It is comprised by functions involving mostly human activities, such as checking and packaging the product and measuring the radiopharmaceutical nuclear activity. Although the dispatch process has well-known steps for its completion, the human factor is the fundamental mechanism of work and control, being susceptible of irregular and instable performance. As a socio-technical system, the risk assessment provided by FRAM may be of importance for safety and quality improvements, even more if considered the nuclear nature of the product, which makes risk assessment critical and mandatory. A system is safe if it is resistant and resilient to perturbations. Identification and assessment of possible risks is, therefore, an essential prerequisite for system safety. Although this seems obvious, most risk assessments are conducted under relative ignorance of the full behavior of the system. Such condition has lead to an approach to assess the risks of intractable systems (i.e., systems that are incompletely described or under specified), namely Resilience Engineering. Into this area, the Functional Resonance Analysis Method has been developed in order to provide concepts, terminology and a set of methods capable of dealing with such systems. The study was conducted following the Functional Resonance Analysis

    There are some positive effects by the introduction of PACS (Picture Archiving Communication System). This study is to analyze the mutual relation between before and after of the introduction of PACS in terms of the environment effect. It is supposed to cause the reduction of developing and fixing wastewater according to the increase in the rate of a non-film. This study also show the amount of wastewater. Target places were the department of image medicine (diagnostic radiation) of the general hospitals in Seoul and Gyeonggido, which are equipped with full PACS. The authors examined questionnaires on the number of projection, the number of indirect projection, the amount of the film used, the number of radiation image CD loan, the amount of the developing and fixing solution used, the change of the amount of fixing wastewater. According to the analysis, we analyzed the change of the amount of developing and fixing solution per a film and the change of the amount of developing and fixing wastewater which is supposed to be reduced proportionally by the introduction of PACS. We got conclusion as below after analyzing 8 hospitals except the largest and the least amount of examination, film used, developing and fixing solution and the amount of developing and fixing wastewater in order to decrease the deviation from 10 general hospitals located in Seoul and Gyeonggido. We compared data one year before adopting PACS Versus 3 years after adopting PACS. The frequencies of examination increased to 7,357.7 cases per month but the amount of film used decreased to 90%, from 42,774.4 to 4,181.88 after adopting the PACS. 3 years after adopting PACS, monthly average amount of developing solution used decreased to 92% and the monthly average amount of fixing solution decreased to 86%. Monthly average amount of developing solution used per film increased to 1.49 times and fixing solution increased as much as three times. Monthly average wastewater for developing decreased to 88

    Full Text Available The Association Agreement between Ukraine and the European Union was ratified in September 2014. Ukraine has undertaken to implement and enforce EU standards, including in the financial sphere, which are regulated by international law. The purpose of the study is to determine the impact of European integration processes on the necessity of the long-term budget forecasting process introduction into the budget process of Ukraine and the revelation of special budgetary rules regulated this process in the EU. The methodology. The list of requirements (budget procedures and rules for their introduction by law into the budget process of Ukraine was determined based on the generalization and systematization of normative legal acts that regulate the medium-term financial planning as the EU standard. The results showed that the long-term budget forecast developing procedure in the budget process will allow the government to timely identify the unfavourable trend in the state’s fiscal policy and introduce preventive measures, determine the full scale of economy’s and business’ reaction to the reforms’ introduction and new laws adoption, estimate fiscal space for fiscal policy implementation for coming years, take into consideration the budget forecast’s indicators during the annual adoption of budget decisions. The study defines the difference between the budget forecast and the planned budget: the forecast is for five years and more, the plan is for one year only; forecast indicators are not mandatory for implementation, they are only guidelines, and planned indicators are mandatory for implementation; the budget forecast is approved by the order of the Cabinet of Ministers of Ukraine and annually specified, the planned budget (for the current budget year is approved by the Verkhovna Rada of Ukraine by adopting the relevant law, amendments are an exception and also approved by law.

    The NRC New Reactor Oversight Process focuses the nuclear safety supervision on the 3 areas: Reactor Safety, Radiation safety and Plant Security. Within the 3 areas, 7 cornerstones are detailed for the purpose. They are Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Occupational Radiation Protection, Public Radiation Safety and Physical Protection. On cooperating with the inspections, the new process ensures a more effective, objective and timely evaluation of the safety level of the operating nuclear power plants. On considering the practices and the status in China nuclear safety supervision, the authors have to learn something from the NRC New Reactor Oversight Process. The authors must make an optimization on Chinese limited resources and put the emphasis on the issues with high risk in order to prevent the occurrence of the accidents. Properly inducing some ideas and methodology from the NRC New Reactor Oversight Process will benefit the development and perfection of the supervision mode of the NNSA

    The development of new extraction processes to produce titanium in powder form leads Powder Metallurgy to an advantage position among the manufacturing processes for titanium. The cost reduction of base material, coupled with the economy of the powder metallurgy processes, give titanium industry the chance to diversify its products, which could lead to production volumes able to stabilise the price of the metal. This work reviews some of the Powder Metallurgy techniques for the manufacturing of titanium parts, and describes the two typical approaches for titanium manufacturing: Blending Elemental and Prealloyed Powders. Among others, conventional pressing and sintering are described, which are compared with cold and hot isostatic pressing techniques. Real and potential applications are described. (Author) 71 refs.

    The central point of ANFs quality philosophy is the process of continuous improvements. With respect to the causes of defects and the efforts needed for elimination, the importance of continuous improvements is evident. In most of the cases, defects are caused in the initial stages of a product but the majority of the problems will be only detected during fabrication and inspection and in the worst case when the product is already in use. Goal of the improvement process is to assure a high product quality. Therefore, the efforts are focused on robust and centered processes. A reasonable quality planning is the basis for achieving and maintaining the quality targets. Quality planning includes prefabrication studies, in-process inspections and final inspections. The inspections provide a large amount of various quality data, process parameters as well as product proper-ties. Key data will be defined and subjected to a statistical analysis. In view of the effectiveness of the analysis, it is important, that the process parameters which influence the characteristics of the product are well known and that appropriate methods for data evaluation and visualization will be used. Main approach of the data visualization is to obtain a tighter control of the product properties and to improve the process robustness by implementation of defined improvements. With respect to the fuel safety and fuel performance, the presentation shows for typical product quality characteristics some examples of visualized quality data. The examples includes the integrity of the pellet column (rod scanner results), the spring force of PWR spacers (critical characteristic with regard to rod fretting) and the spacer intersection weld size (thermo-hydraulic fuel bundle behaviour). The presentation also includes an example for the statistical process control, the in-line surveillance of the fuel rod weld parameters which assures the integrity of the welds within tight tolerance ranges.

    Lakes are bodies of water formed in depressions on the earth's surface, and as such, act as depositories for a variety of chemical and biological materials. The study of lakes has become increasingly prevalent in recent years. Lakes are a valuable resource, and their multiple uses have made them susceptible to water-quality problems such as algal blooms, sediment deposition and fish kills. These problems are products of the eutrophication process (enrichment, aging and extinction of lakes), which is often accelerated by man. Therefore, it becomes important to understand the properties and processes of lakes which govern lake enrichment, and the measures available to control enrichment.

    A new chemical introduction process of fluorine-18, 18 F was developed using solid phase synthesis technique, instead of a conventional liquid phase synthesis. Separation for a plenty of non-reaction compound was difficult in the liquid phase synthesis technique. Precursor compound reacted on the surface of solid phase (beads). Labeled compound with 18 F could be separated from the solid surface by reaction of fluoride reagent. A fundamental fluoric reaction was developed with the solid phase process. Sulfonyl chloride, polymer-bound 1 was used as a solid phase carrier of the precursor. The 18 F-FDG, which are replaced a hydroxyl group in D-glucose with 18 F, were used most frequently as a cancer marker in positron computed tomography (PET). Synthesis of the 18 F-FDG was investigated by the solid phase technique. (M. Suetake)

    2016-01-01

    This textbook for undergraduate mathematics, science, and engineering students introduces the theory and applications of discrete Fourier and wavelet transforms using elementary linear algebra, without assuming prior knowledge of signal processing or advanced analysis.It explains how to use the Fourier matrix to extract frequency information from a digital signal and how to use circulant matrices to emphasize selected frequency ranges. It introduces discrete wavelet transforms for digital signals through the lifting method and illustrates through examples and computer explorations how these transforms are used in signal and image processing. Then the general theory of discrete wavelet transforms is developed via the matrix algebra of two-channel filter banks. Finally, wavelet transforms for analog signals are constructed based on filter bank results already presented, and the mathematical framework of multiresolution analysis is examined.

  12. Selective Separation of Trivalent Actinides from Lanthanides by Aqueous Processing with Introduction of Soft Donor Atoms

    International Nuclear Information System (INIS)

    Nash, Kenneth L.

    2009-01-01

    Implementation of a closed loop nuclear fuel cycle requires the utilization of Pu-containing MOX fuels with the important side effect of increased production of the transplutonium actinides, most importantly isotopes of Am and Cm. Because the presence of these isotopes significantly impacts the long-term radiotoxicity of high level waste, it is important that effective methods for their isolation and/or transmutation be developed. Furthermore, since transmutation is most efficiently done in the absence of lanthanide fission products (high yield species with large thermal neutron absorption cross sections) it is important to have efficient procedures for the mutual separation of Am and Cm from the lanthanides. The chemistries of these elements are nearly identical, differing only in the slightly stronger strength of interaction of trivalent actinides with ligand donor atoms softer than O (N, Cl-, S). Research being conducted around the world has led to the development of new reagents and processes with considerable potential for this task. However, pilot scale testing of these reagents and processes has demonstrated the susceptibility of the new classes of reagents to radiolytic and hydrolytic degradation. In this project, separations of trivalent actinides from fission product lanthanides have been investigated in studies of (1) the extraction and chemical stability properties of a class of soft-donor extractants that are adapted from water-soluble analogs, (2) the application of water soluble soft-donor complexing agents in tandem with conventional extractant molecules emphasizing fundamental studies of the TALSPEAK Process. This research was conducted principally in radiochemistry laboratories at Washington State University. Collaborators at the Radiological Processing Laboratory (RPL) at the Pacific Northwest National Laboratory (PNNL) have contributed their unique facilities and capabilities, and have supported student internships at PNNL to broaden their

  13. INTRODUCTION TO THE ANALYSIS OF THE MECHANICS OF THE DIAMOND GRINDING PROCESS WITH THE ACCOUNT OF WEAR OF WHEEL GRAINS

    Directory of Open Access Journals (Sweden)

    Feodor NOVIKOV

    2017-12-01

    Full Text Available The work is devoted to the theoretical analysis of the mechanics of the diamond grinding process, taking into account the wear of the wheel grains for scientifically based choice of optimal processing conditions. A multiplicative probabilistic approach to the generalization of the cutting profile of a diamond grinding wheel in its consideration in a state of some steady wear during processing is considered. This is achieved by working the wheel in a mode of properly established self-sharpening or with the use of effective dressing methods. In this case, the linear wear of individual grains of diamond abrasive located on the working surface of the grinding wheel and opened to mechanical contact with the material being processed is assumed to proportionally to the depth of the introduction of grain into it. The analytical dependence of the maximum thickness of the cut is presented, and the relationship between the maximum grain wear and the accepted universal relative characteristic of the steady wear with the operational parameters of the tool and the grinding mode is shown. The obtained results can be used in the development of analytical models of processing productivity and microgeometric engineering of the treated surface, new approaches to increasing the efficiency of diamond grinding. The research is based on modern technical possibilities of controlling the state of the cutting relief of diamond-abrasive tools, especially in electro-physical-mechanical grinding technologies, for example, using the diamond-spark method developed at the Kharkov Polytechnic Institute.

    The paper reported the R and D of the membrane separation process introduction technology during a period of 1994 through 1998. The membrane separation technology is not associated with the phase change which requires large energy and expected to be an energy saving process. For the production of membranes required of high functions, the vapor deposition polymerization method was considered, and high order structure control of the membrane, control of adhesion and attachment, and control of orientation, and development of the high polymerization technology were required. For the high grade control of vapor polymerization, the substrate surface structure/quality were important. The molecular level analysis of the vapor deposition surface was also needed. Therefore, the paper took notice of STM (scanning tunneling microscopy), AFM (atomic force microscopy) and HREELS (high resolution electron energy loss spectroscopy) as surface atomic/molecular configuration analysis technology, and designed/fabricated and studied the high resolving power and high sensitivity analysis equipment using the analysis equipment which combined HREELS and STM and the analysis equipment using SFG (sum frequency generation) which can detect signals in the low frequency region. Making full use of the highest technology, technology was able to be developed for substrate surface analysis and surface reaction analysis technologies which become the basis of the high performance separation membrane fabrication technology by the vapor deposition polymerization method indispensable for introduction of the membrane separation process. The technology can be the base applicable to a lot of fields where surfaces and interfaces are concerned

    Na), Wu Y. N.(Yun; Yu), Yan H. Y.(Hong; Jun), Huang Z. J.(Zhi

    Construction industries consume more energy resources than necessary. it is essential to establish a management system with all pollution problems resolved to construct green buildings. By applying the theory of whole life cycle, this paper divides the whole process of construction into four sub-phases, which will also be subdivided into more concrete working procedures. Based on this, a systematic framework is promoted for the green management of the construction, especially and creatively, considering the green aims as important as the traditional three aims-"quality aim, schedule aim and cost aim". This framework, adhering to the integration idea-"customers first, whole optimal", regards the green control and workflow as an organic whole in order to build green, sustainable and healthy architecture, and then provide a perfect guide and reference to the green management.

  17. Processes and patterns of interaction as units of selection: An introduction to ITSNTS thinking.

    Many practicing biologists accept that nothing in their discipline makes sense except in the light of evolution, and that natural selection is evolution's principal sense-maker. But what natural selection actually is (a force or a statistical outcome, for example) and the levels of the biological hierarchy (genes, organisms, species, or even ecosystems) at which it operates directly are still actively disputed among philosophers and theoretical biologists. Most formulations of evolution by natural selection emphasize the differential reproduction of entities at one or the other of these levels. Some also recognize differential persistence, but in either case the focus is on lineages of material things: even species can be thought of as spatiotemporally restricted, if dispersed, physical beings. Few consider-as "units of selection" in their own right-the processes implemented by genes, cells, species, or communities. "It's the song not the singer" (ITSNTS) theory does that, also claiming that evolution by natural selection of processes is more easily understood and explained as differential persistence than as differential reproduction. ITSNTS was formulated as a response to the observation that the collective functions of microbial communities (the songs) are more stably conserved and ecologically relevant than are the taxa that implement them (the singers). It aims to serve as a useful corrective to claims that "holobionts" (microbes and their animal or plant hosts) are aggregate "units of selection," claims that often conflate meanings of that latter term. But ITSNS also seems broadly applicable, for example, to the evolution of global biogeochemical cycles and the definition of ecosystem function.

    Full Text Available The topic of this volume is a result from The Contemporary City in Serbia and Bulgaria: Processes and Changes, a bilateral project of the Institute of Ethnography of the Serbian Academy of Sciences and Arts and the Institute of Ethnology and Folklore Studies with Ethnographic Museum of the Bulgarian Academy of Sciences (2014-2016. The six papers offer a comparative view of current social processes in two neighbouring Balkan countries, linked by numerous historical and political experiences. Comparative research into societal trends enables a more thorough understanding and monitoring of global processes. In today’s increasingly globalised and glocalised world, towns experience sudden changes and it is in the towns that these changes are most vividly to be seen. The focus of our research is on the dynamism of the contemporary town, on processuality and changes in societal practices. Ana Luleva examines life in the small town of Nessebar in southeast Bulgaria, which has been on the UNESCO World Heritage list since 1983. The protection, management and presentation of Nessebar’s cultural heritage are highly complex issues, further complicated by the problem of collision with the interests of the inhabitants. The author analyses the relations between the various factors - the state administration, municipal authorities and the local population. Here the tourist industry, investment interests, corrupt institutions and civil society all play their part. Ivanka Petrova chose to research Belogradchik, a small town in northwest Bulgaria. Petrova investigates how local social and cultural resources are used in the work of a family tourist enterprise. The author looks for answers to questions such as: how its members identify with the town and its culture and how the work of the enterprise fits into the Belogradchik local context. At the focus of her paper are current societal practices: the local urban economy and the production of images and symbols

    To date, Pumped Hydro Storage (PHS) is practically the only technology used to store large quantities of electricity. There are however other ways to achieve the same goal. There are not yet well known, because the interest for large scale storage is quite new A complete family of storage technologies can be defined as 'Thermodynamic Storage Systems'. Their only common factor is that a gas is pumped and expanded in the process. If the gas is air taken from the atmosphere and discharged to it, the system is said 'an open system'. This is already developed in the form of Compressed Air Energy Storage (CAES). Different embodiments are possible, following the way the heat gene - rated during the compression stage is conserved. The compressed air is generally stored in underground caverns created in deep salt formations. 2 installations are presently operating and many projects are envisaged. if the gas circulates in closed loop within the plant, the system is said 'a closed system' In this case, the energy is stored as heat and/or cold at different temperature levels. A great variety of technologies can be imagined and are under development, using different gases (e.g. argon, CO 2 ) and different temperature ranges. PHS and CAES require specific sites for water reservoirs or underground caverns. The dosed systems can be installed basically anywhere. (author)

    Global Positioning System (GPS) Radio Occultation (RO) technique has been used to investigate the Earth's atmosphere since 1990s. In 2006, Taiwan has launched six low Earth orbit (LEO) satellites as a RO constellation mission, named FORMOSAT-3 /COSMIC (F-3/C). F-3/C mission can release 1500-2500 data sets per day for both neutral atmosphere and ionosphere. With the advent of Global Navigation Satellite System (GNSS) in ten years and FORMOSAT-7/COSMIC-2 (F-7/C-2) mission, 12 LEO satellites are planned to be launched and deployed in two clusters of 6-satellites into the designated low and high inclination orbits in 2017 and 2020(TBD), respectively. The amount of RO data set will increase to about 8000 set per day with the using of GNSS TriG (GPS, Glonass, Galileo) receivers. The first phase of FS-7 mission is designed to low inclination (24 deg) orbit to improve the ability of server weather forecasting, like typhoon and monsoon rainfall around tropical region. The second is high inclination (72 deg) for global distribution. In order to observe better water vapor profiles, the 4x3 antennas arrays will be on board to receive weak signals which pass through low troposphere around earth surface. This report will introduce the status of F-7/C-2 mission and atmospheric part of occultation data process software TROPS.

    The decision-making process to introduce new vaccines into national immunization programmes is often complex, involving many stakeholders who provide technical information, mobilize finance, implement programmes and garner political support. Stakeholders may have different levels of interest, knowledge and motivations to introduce new vaccines. Lack of consensus on the priority, public health value or feasibility of adding a new vaccine can delay policy decisions. Efforts to support country-level decision-making have largely focused on establishing global policies and equipping policy makers with the information to support decision-making on new vaccine introduction (NVI). Less attention has been given to understanding the interactions of policy actors and how the distribution of influence affects the policy process and decision-making. Social network analysis (SNA) is a social science technique concerned with explaining social phenomena using the structural and relational features of the network of actors involved. This approach can be used to identify how information is exchanged and who is included or excluded from the process. For this SNA of vaccine decision-making in Nigeria, we interviewed federal and state-level government officials, officers of bilateral and multilateral partner organizations, and other stakeholders such as health providers and the media. Using data culled from those interviews, we performed an SNA in order to map formal and informal relationships and the distribution of influence among vaccine decision-makers, as well as to explore linkages and pathways to stakeholders who can influence critical decisions in the policy process. Our findings indicate a relatively robust engagement of key stakeholders in Nigeria. We hypothesized that economic stakeholders and implementers would be important to ensure sustainable financing and strengthen programme implementation, but some economic and implementation stakeholders did not appear centrally on

    Full Text Available Cashless payments are recent phenomena, which even increased with the introduction of contactless means like NFC, PayPass or payWave. Such new methods speed-up the entire payment process and in comparison to cash transactions are much simpler and faster. But on the other hand the key question for merchant is if it is worth to have such device, which accept these new payment means or not to have the terminal at all. What is the amount of cash flow, which delimits the cash holdings to be still profitable? This paper tries to give answers to such question by presenting general profitability model, which will address defining the cash threshold amount. The aim is to show that cash holdings could be profitable up to certain amount, but after the threshold is met, cashless payment methods are fairly superior despite their additional costs.

    OBJECTIVE: Identifying at what age infants enrolled in public day care centers are introduced to soft drinks and industrialized juice, as well as comparing the nutritional composition of these goods with natural fruit juice. METHODS: A cross-sectional study with the mothers of 636 children (aged 0 to 36 months) from nurseries of day care centers, who were asked questions about the age of feeding introduction. This study evaluated the proximate composition of soft drinks and artificial juice, comparing them with those of natural fruit juice regarding energy, sugar, fiber, vitamin C, and sodium values. The chemical composition of fruit juice was obtained by consulting the Table of Food Composition and, for industrialized drinks, the average nutritional information on the labels of the five most consumed product brands. RESULTS: The artificial drinks were consumed before the first year of life by more than half of the children studied, however, approximately 10% consumed them before the age of 6 months. With regard to the comparison among the drinks, artificial fruit juice beverages and soft drinks proved to contain from nine to 13 times higher amounts of sodium, and 15 times less vitamin C than natural juices. CONCLUSIONS: The introduction of soft drinks and industrialized juice in the diet of infants was inopportune and premature.. When compared to natural fruit juice, these have inferior nutritional composition, which suggests the urgent need for measures based on strategies for food and nutrition education in order to promote awareness and the maintenance of healthy eating habits.

With regard to the comparison among the drinks, artificial fruit juice beverages and soft drinks proved to contain from nine to 13 times higher amounts of sodium, and 15 times less vitamin C than natural juices. CONCLUSIONS: The introduction of soft drinks and industrialized juice in the diet of infants was inopportune and premature.. When compared to natural fruit juice, these have inferior nutritional composition, which suggests the urgent need for measures based on strategies for food and nutrition education in order to promote awareness and the maintenance of healthy eating habits.

    2016-09-01

    There currently appears to be a general consensus on the relationship between time perspective and aging, such that (a) future time is perceived as more limited with age and (b) older people are more present-focused and less future-focused than younger people. At the same time, there are debates about whether these age differences are positively related to well-being and to what extent there are boundary conditions beyond which these age differences would cease to occur. The 8 manuscripts included in this Special Issue attempt to shed light on these debates. In doing so, they refine the dominant theoretical perspective on the topic-socioemotional selectivity theory-and introduce new theoretical perspectives. New measures and methodologies for studying time perspective and aging are also discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  8. Paper Study Evaluations Of The Introduction Of Small Column Ion Exchange Waste Streams To The Defense Waste Processing Facility

    International Nuclear Information System (INIS)

    Fox, K.; Edwards, T.; Stone, M.; Koopman, D.

    2010-01-01

    The objective of this paper study is to provide guidance on the impact of Monosodium Titanate (MST) and Crystalline Silicotitanate (CST) streams from the Small Column Ion Exchange (SCIX) process on the Defense Waste Processing Facility (DWPF) flowsheet and glass waste form. A series of waste processing scenarios was evaluated, including projected compositions of Sludge Batches 8 through 17 (SB8 through SB17), MST additions, CST additions to Tank 40 or to a sludge batch preparation tank (Tank 42 or Tank 51, referred to generically as Tank 51 in this report), streams from the Salt Waste Processing Facility (SWPF), and two canister production rates. A wide array of potential glass frit compositions was used to support this assessment. The sludge and frit combinations were evaluated using the predictive models in the current DWPF Product Composition Control System (PCCS). The results were evaluated based on the number of frit compositions available for a particular sludge composition scenario. A large number of candidate frit compositions (e.g., several dozen to several hundred) is typically a good indicator of a sludge composition for which there is flexibility in forming an acceptable waste glass and meeting canister production rate commitments. The MST and CST streams will significantly increase the concentrations of certain components in glass, such as Nb 2 O 5 , TiO 2 , and ZrO 2 , to levels much higher than have been previously processed at DWPF. Therefore, several important assumptions, described in detail in the report, had to be made in performing the evaluations. The results of the paper studies, which must be applied carefully given the assumptions made concerning the impact of higher Ti, Zr, and Nb concentrations on model validity, provided several observations: (1) There was difficulty in identifying a reasonable number of candidate frits (and in some cases an inability to identify any candidate frits) when a waste loading of 40% is targeted for Sludge

    2016-07-01

    Full Text Available The seventh issue of Complex Systems Informatics and Modeling Quarterly presents five papers devoted to two distinct research topics: systems modeling and natural language processing (NLP. Both of these subjects are very important in computer science. Through modeling we can simplify the studied problem by concentrating on only one aspect at a time. Moreover, a properly constructed model allows the modeler to work on higher levels of abstraction and not having to concentrate on details. Since the size and complexity of information systems grows rapidly, creating good models of such systems is crucial. The analysis of natural language is slowly becoming a widely used tool in commerce and day to day life. Opinion mining allows recommender systems to provide accurate recommendations based on user-generated reviews. Speech recognition and NLP are the basis for such widely used personal assistants as Apple’s Siri, Microsoft’s Cortana, and Google Now. While a lot of work has already been done on natural language processing, the research usually concerns widely used languages, such as English. Consequently, natural language processing in languages other than English is very relevant subject and is addressed in this issue.

    Objective To describe the process of preparation and response of local health authorities in key public health issues while facing the introduction stage of an unusual virus: Chikungunya in Colombia in 2014. Methods A cross-sectional study was conducted using a survey that was developed for this study and sent to Public Health coordinators and to the person in charge of vector borne-diseases in the country's territorial entities. Results 23 out of the 35 territories at risk from the transmission of Chikungunya agreed to answer the survey. A global review of the survey scores for each evaluated section shows better performances in the areas of knowledge management, comprehensive patient care, epidemiological intelligence, and health promotion. According to the results of this study, the epidemiological surveillance system during the Chikungunya epidemic had a low acceptability and flexibility, possibly contributing to the underreporting of cases. Conclusions In general, knowledge and implementation by local authorities of the Integrated Health Strategy- EGI (Estrategia de Gestión Integral, by its Spanish acronym)- for vector-borne diseases was evident from the themes evaluated in this study. However, it is necessary to reinforce the communication of risks, laboratory, and outbreak and contingencies management areas faced during the introduction of new viruses.

    How dynamical systems store and process information is a fundamental question that touches a remarkably wide set of contemporary issues: from the breakdown of Moore's scaling laws--that predicted the inexorable improvement in digital circuitry--to basic philosophical problems of pattern in the natural world. It is a question that also returns one to the earliest days of the foundations of dynamical systems theory, probability theory, mathematical logic, communication theory, and theoretical computer science. We introduce the broad and rather eclectic set of articles in this Focus Issue that highlights a range of current challenges in computing and dynamical systems.

    Full Text Available This paper presents a case study on how design is taught in a second-semester introductory course of the Architecture and Urbanism undergraduate program at the Rio de Janeiro Federal University (UFRJ, in which teacher-student interactions are utilized as fundamental strategies to accomplish the course goals. The findings are based on the author’s experience as a professor of the Architectural Form Conception (CFA 2 course in the Form Analysis and Representation Department at that school. This particular learning method represents a specific approach toward the development of the design process, an approach that is part of a larger set of discussions and experimentations to prepare architectural students to design objects of architecture. Using everyone’s commitments to the established goals, the main objective is to broaden students’ awareness, to provide a critical stance on the thought and accomplishment process, and to encourage them to go beyond stereotypes and ephemeral contemporary attitudes in which excessive information numbs motivation and dulls reflexive talent.

    Electronically stored clinical documents may contain both structured data and unstructured data. The use of structured clinical data varies by facility, but clinicians are familiar with coded data such as International Classification of Diseases, Ninth Revision, Systematized Nomenclature of Medicine-Clinical Terms codes, and commonly other data including patient chief complaints or laboratory results. Most electronic health records have much more clinical information stored as unstructured data, for example, clinical narrative such as history of present illness, procedure notes, and clinical decision making are stored as unstructured data. Despite the importance of this information, electronic capture or retrieval of unstructured clinical data has been challenging. The field of natural language processing (NLP) is undergoing rapid development, and existing tools can be successfully used for quality improvement, research, healthcare coding, and even billing compliance. In this brief review, we provide examples of successful uses of NLP using emergency medicine physician visit notes for various projects and the challenges of retrieving specific data and finally present practical methods that can run on a standard personal computer as well as high-end state-of-the-art funded processes run by leading NLP informatics researchers.

  19. A new nebulization device with exchangeable aerosol generation mode as a useful tool to investigate sample introduction processes in inductively coupled plasma atomic emission spectrometry

    International Nuclear Information System (INIS)

    Grotti, Marco; Lagomarsino, Cristina; Frache, Roberto

    2004-01-01

    A new sample introduction device has been designed in order to differentiate between the effects of the aerosol production and its following desolvation on analytical performances of an inductively coupled plasma optical spectrometer. This research tool allows to easily switch between the pneumatic and ultrasonic aerosol generation mode and to use a joint desolvation chamber. In this way, a real comparison between aerosol production systems may be attained and the influence of aerosol generation process on analytical figures clearly distinguished from that of the desolvation process. In this work, the separate effects of the aerosol generation and desolvation processes on analytical sensitivity and tolerance towards matrix effects have been investigated. Concerning sensitivity, it was found that both the processes play an important role in determining emission intensities, being the increase in sensitivity due to desolvation higher than that due to the improved aerosol generation efficiency. Concerning the matrix effects, a predominant role of the desolvation system was found, while the influence of the aerosol generation mode was much less important. For nitric acid, the decreasing effect was mitigated by the presence of a desolvation system, due to partial removal of the acid. On the contrary, the depressive effect of sulfuric acid was enhanced by the presence of a desolvation system, due to degradation of the solvent removal efficiency and to further decrease in the analyte transport rate caused by clustering phenomena. Concerning the interferences due to sodium and calcium, a depressive effect was observed, which is enhanced by desolvation

    Gomberg, Joan

    2010-01-01

    This paper introduces the special section on the "phenomenology, underlying processes, and hazard implications of aseismic slip and nonvolcanic tremor" by highlighting key results of the studies published in it. Many of the results indicate that seismic and aseismic manifestations of slow slip reflect transient shear displacements on the plate interface, with the outstanding exception of northern Cascadia where tremor sources have been located on and above the plate interface (differing models of the plate interface there also need to be reconciled). Slow slip phenomena appear to result from propagating deformation that may develop with persistent gaps and segment boundaries. Results add to evidence that when tectonic deformation is relaxed via slow slip, most relaxation occurs aseismically but with seismic signals providing higher-resolution proxies for the aseismic slip. Instead of two distinct slip modes as suggested previously, lines between "fast" and "slow" slip more appropriately may be described as blurry zones. Results reported also show that slow slip sources do not coincide with a specific temperature or metamorphic reaction. Their associations with zones of high conductivity and low shear to compressional wave velocity ratios corroborate source models involving pore fluid pressure buildup and release. These models and spatial anticorrelations between earthquake and tremor activity also corroborate a linkage between slow slip and frictional properties transitional between steady state and stick-slip. Finally, this special section highlights the benefits of global and multidisciplinary studies, which demonstrate that slow phenomena are not confined to beneath the locked zone but exist in many settings.

    2015-04-01

    From the 2013 ECSA conference 'Estuaries and Coastal Areas in Times of Intense Change' a theme emerged that has ended up being the focus of this Special Issue of Estuarine Coastal and Shelf Science, namely 'Changes to processes in estuaries and coastal waters due to intense multiple pressures'. Many parts of the world are continuing to experience unprecedented rates of economic growth, and those responsible for managing coastal and estuarine areas must respond accordingly. At the same time, global climate change and sea level rise are also continuing, placing new or more intense pressures on coastal areas that must be dealt with in ways that are as far as possible managed as a result of good scientific understanding. There are other pressures too, which depend on the system concerned. This article provides an overview of the papers contained within the Special Issue and provides a discussion of how these fit within the main theme of intense multiple stressors, considering how a balance can be achieved between the needs of various different stakeholders and interest groups, and the sustainability of the system concerned. We categorise the papers in four main groupings: (1) stressors related to sea level rise; (2) stressors related to changes in fresh water inputs; (3) stressors related to anthropogenic pollution; and (4) the use of indicators as a means of assessing the effects of stressors, and reflect on the fact that despite the diversity of different challenges and geographical regions involved many of the approaches and discussions contained within the Special Issue have strong similarities, leading to a set of overarching principles that should be considered when making recommendations on management strategies.

    2018-02-01

    Full Text Available For the majority of Belgian hospitals, a pharmacist-led full medication review process is not standard care and, therefore, challenging to introduce. With this study, we aimed to evaluate the successes and barriers of the implementation of a pharmacist-led full medication review process in the geriatric ward at a local Belgian hospital. To this end, we carried out an interventional study, performing a full medication review on older patients (≥70 years with polypharmacy (≥5 drugs who had an unplanned admission to the geriatric ward. The process consisted of 3 steps: (1 medication reconciliation upon admission; (2 medication review using an explicit reviewing tool (STOPP/START criteria or GheOP3S tool, followed by a discussion between the pharmacist and the geriatrician; and (3 medication reconciliation upon discharge. Ethical approval was obtained from the Ethical Commission of the Ghent University Hospital. Outcomes included objective data on the interventions (e.g., number of drug discrepancies; number of potentially inappropriate prescriptions (PIP; as well as subjective experiences (e.g., satisfaction with service; opinion on inter-professional communication. There was a special focus on communication aspects within the introduction of this process. In total, 52 patients were included in the study, taking a median of 10 drugs (IQR 8–12. Upon admission, 122 drug discrepancies were detected. During medication review, 254 PIPs were detected and discussed, leading to an improvement in the appropriateness of medication use. The satisfaction of community pharmacists concerning additional communication and the satisfaction of the patients after counselling at discharge were positive. However, several barriers were encountered, such as the time-consuming process to gather necessary information from different sources, the non-continuity of the service due to the lack of trained personnel or the lack of safe, electronic platforms to share

  12. Assimilation of flood extent data with 2D flood inundation models for localised intense rainfall events

    Remote sensing of flood inundation extent has long been a potential source of data for constraining and correcting simulations of floodplain inundation. Hydrodynamic models and the computing resources to run them have developed to the extent that simulation of flood inundation in two-dimensional space is now feasible over large river basins in near real-time. However, despite substantial evidence that there is useful information content within inundation extent data, even from low resolution SAR such as that gathered by Envisat ASAR in wide swath mode, making use of the information in a data assimilation system has proved difficult. He we review recent applications of the Ensemble Kalman Filter (EnKF) and Particle Filter for assimilating SAR data, with a focus on the River Severn UK and compare these with complementary research that has looked at the internal error sources and boundary condition errors using detailed terrestrial data that is not available in most locations. Previous applications of the EnKF to this reach have focused on upstream boundary conditions as the source of flow error, however this description of errors was too simplistic for the simulation of summer flood events where localised intense rainfall can be substantial. Therefore, we evaluate the introduction of uncertain lateral inflows to the ensemble. A further limitation of the existing EnKF based methods is the need to convert flood extent to water surface elevations by intersecting the shoreline location with a high quality digital elevation model (e.g. LiDAR). To simplify this data processing step, we evaluate a method to directly assimilate inundation extent as a EnKF model state rather than assimilating water heights, potentially allowing the scheme to be used where high-quality terrain data are sparse.

    The development of a wide array of process technologies to enable the shift from conventional biological wastewater treatment processes to resource recovery systems is matched by an increasing demand for predictive capabilities. Mathematical models are excellent tools to meet this demand. However, obtaining reliable and fit-for-purpose models remains a cumbersome task due to the inherent complexity of biological wastewater treatment processes. In this work, we present a first study in the context of environmental biotechnology that adopts and explores the use of extents as a way to simplify and streamline the dynamic process modeling task. In addition, the extent-based modeling strategy is enhanced by optimal accounting for nonlinear algebraic equilibria and nonlinear measurement equations. Finally, a thorough discussion of our results explains the benefits of extent-based modeling and its potential to turn environmental process modeling into a highly automated task.

    Full Text Available The introduction starts from the exhaustion of modernity, drawing the fundamental lines of its development inside Western historical experience. The end of the political nexus between theology and politics, the evanescence of nation-state sovereignty, the check of great historical interpretations reveal the necessity of new categories and new organizational models, able to make us answer to the violence that the ongoing processes are liberating. Schiera underlines in particular the relevance of the administrative apparatus because of its capacity to link the global government with global organization, human rights and the commons.

  2. To what extent can the nuclear public relations be effective?

    Energy Technology Data Exchange (ETDEWEB)

    Ohnishi, Teruaki [CRC Research Institute, Tokyo (Japan)

    1996-06-01

    The effect of public relations (PRs) on the public`s attitude to nuclear energy was assessed using a model developed under the assumption that the extent of attitude change of the public by the PRs activity is essentially the same as that by the nuclear information released by the newsmedia. The attitude change of the public was quantitatively estimated by setting variables explicitly manifesting the activities such as the circulation of exclusive publicity and the area of advertising messages in the newspaper as parameters. The public`s attitude became clear to have a nonlinear dependence on the amount of activity, the extent of its change being varied considerably with demographic classes. Under a given financial condition, the offer of PRs information to the people, as many as possible in a target region, in spite of its little force of appeal, was found to be more effective for the amelioration of public attitude than the repeated offer of the information to a limited member of the public. It also became clear that there exists the most effective media mix for the activity depending on the extent of target region and on the target class of demography, therefore, it is quite significant to determine beforehand the proper conditions for the activity to be executed, such a situation indicating the need for the introduction of nuclear PRs management.

    Alien microbes, fungi, plants and animals occur on most of the sub-Antarctic islands and some parts of the Antarctic continent. These have arrived over approximately the last two centuries, coincident with human activity in the region. Introduction routes have varied, but are largely associated with movement of people and cargo in connection with industrial, national scientific program and tourist operations. The large majority of aliens are European in origin. They have both direct and indirect impacts on the functioning of species-poor Antarctic ecosystems, in particular including substantial loss of local biodiversity and changes to ecosystem processes. With rapid climate change occurring in some parts of Antarctica, elevated numbers of introductions and enhanced success of colonization by aliens are likely, with consequent increases in impacts on ecosystems. Mitigation measures that will substantially reduce the risk of introductions to Antarctica and the sub-Antarctic must focus on reducing propagule loads on humans, and their food, cargo, and transport vessels.

  5. Introduction to bioinformatics.

    Can, Tolga

    2014-01-01

    Bioinformatics is an interdisciplinary field mainly involving molecular biology and genetics, computer science, mathematics, and statistics. Data intensive, large-scale biological problems are addressed from a computational point of view. The most common problems are modeling biological processes at the molecular level and making inferences from collected data. A bioinformatics solution usually involves the following steps: Collect statistics from biological data. Build a computational model. Solve a computational modeling problem. Test and evaluate a computational algorithm. This chapter gives a brief introduction to bioinformatics by first providing an introduction to biological terminology and then discussing some classical bioinformatics problems organized by the types of data sources. Sequence analysis is the analysis of DNA and protein sequences for clues regarding function and includes subproblems such as identification of homologs, multiple sequence alignment, searching sequence patterns, and evolutionary analyses. Protein structures are three-dimensional data and the associated problems are structure prediction (secondary and tertiary), analysis of protein structures for clues regarding function, and structural alignment. Gene expression data is usually represented as matrices and analysis of microarray data mostly involves statistics analysis, classification, and clustering approaches. Biological networks such as gene regulatory networks, metabolic pathways, and protein-protein interaction networks are usually modeled as graphs and graph theoretic approaches are used to solve associated problems such as construction and analysis of large-scale networks.

    2010-01-01

    A brief review of the basic principles of fluid mechanics needed for development of linear and nonlinear ultrasonic concepts will be given. The fundamental equations of nonlinear ultrasonics will be derived and their physical properties explained. It will be shown how an originally monochromatic finite-amplitude ultrasonic wave, due to nonlinear effects, will distort during its propagation in time and space to form higher harmonics to its fundamental frequency. The concepts of shock formation will be presented. The material nonlinearity, described by the nonlinearity parameter B/A of the material, and the convective nonlinearity, described by the ultrasonic Mach Number, will be explained. Two procedures for determination of B/A will briefly be described and some B/A-values characterizing biological materials will be presented. Shock formation, described by use of the Goldberg Number,and Ultrasonic Saturation will be discussed.. An introduction to focused ultrasonic fields will be given and it will be shown how the ultrasonic intensity will vary axially and laterally in and near the focal region and how the field parameters of interest to biomedical applications may be described by use of the KZK-Model. Finally, an introduction will be given to the parametric acoustic array formed by mixing and interaction of two monochromatic, finite-amplitude ultrasonic waves in a liquid and the potentials of this mixing process in biomedical ultrasound will briefly be mentioned.

    International Nuclear Information System (INIS)

    Mathews, J.T.

    1991-01-01

    The author introduces a collection of papers by US scientists concerned with the need for a regime to control global warming. The papers were prepared in the interest of stimulating the widest possible consideration of the choices that may be faced at the United Nations Conference on Environment and Development in June of 1992. Several papers present the argument that a climate regime will take the form of a general framework convention followed by implementing protocols, following the model of the Vienna convention and its subsequent Montreal protocol. Subsequent papers shift the focus from the form of specific agreements to the continuing process of which treaties are a part. The author follows this introduction with her own viewpoint of strategies for a regime to control greenhouse warming

    Etheridge, Alison M

    2000-01-01

    Over the past 20 years, the study of superprocesses has expanded into a major industry and can now be regarded as a central theme in modern probability theory. This book is intended as a rapid introduction to the subject, geared toward graduate students and researchers in stochastic analysis. A variety of different approaches to the superprocesses emerged over the last ten years. Yet no one approach superseded any others. In this book, readers are exposed to a number of different ways of thinking about the processes, and each is used to motivate some key results. The emphasis is on why results are true rather than on rigorous proof. Specific results are given, including extensive references to current literature for their general form.

  10. Introduction to morphogenetic computing

    CERN Document Server

    Resconi, Germano; Xu, Guanglin

    2017-01-01

    This book offers a concise introduction to morphogenetic computing, showing that its use makes global and local relations, defects in crystal non-Euclidean geometry databases with source and sink, genetic algorithms, and neural networks more stable and efficient. It also presents applications to database, language, nanotechnology with defects, biological genetic structure, electrical circuit, and big data structure. In Turing machines, input and output states form a system – when the system is in one state, the input is transformed into output. This computation is always deterministic and without any possible contradiction or defects. In natural computation there are defects and contradictions that have to be solved to give a coherent and effective computation. The new computation generates the morphology of the system that assumes different forms in time. Genetic process is the prototype of the morphogenetic computing. At the Boolean logic truth value, we substitute a set of truth (active sets) values with...

  12. Introduction to Computational Plasticity

    International Nuclear Information System (INIS)

    Hartley, P

    2006-01-01

    The focus of the book on computational plasticity embodies techniques of relevance not only to academic researchers, but also of interest to industrialists engaged in the production of components using bulk or sheet forming processes. Of particular interest is the guidance on how to create modules for use with the commercial system Abaqus for specific types of material behaviour. The book is in two parts, the first of which contains six chapters, starting with microplasticity, but predominantly on continuum plasticity. The first chapter on microplasticty gives a brief description of the grain structure of metals and the existence of slip systems within the grains. This provides an introduction to the concept of incompressibility during plastic deformation, the nature of plastic yield and the importance of the critically resolved shear stress on the slip planes (Schmid's law). Some knowledge of the notation commonly used to describe slip systems is assumed, which will be familiar to students of metallurgy, but anyone with a more general engineering background may need to undertake additional reading to understand the various descriptions. Chapter two introduces one of several yield criteria, that normally attributed to von Mises (though historians of mechanics might argue over who was first to develop the theory of yielding associated with strain energy density), and its two or three-dimensional representation as a yield surface. The expansion of the yield surface during plastic deformation, its translation due to kinematic hardening and the Bauschinger effect in reversed loading are described with a direct link to the material stress-strain curve. The assumption, that the increment of strain is normal to the yield surface, the normality principle, is introduced. Uniaxial loading of an elastic-plastic material is used as an example in which to develop expressions to describe increments in stress and strain. The full presentation of numerous expressions, tensors and

  3. Extent of reaction in open systems with multiple heterogeneous reactions

    Science.gov (United States)

    Friedly, John C.

    1991-01-01

    The familiar batch concept of extent of reaction is reexamined for systems of reactions occurring in open systems. Because species concentrations change as a result of transport processes as well as reactions in open systems, the extent of reaction has been less useful in practice in these applications. It is shown that by defining the extent of the equivalent batch reaction and a second contribution to the extent of reaction due to the transport processes, it is possible to treat the description of the dynamics of flow through porous media accompanied by many chemical reactions in a uniform, concise manner. This approach tends to isolate the reaction terms among themselves and away from the model partial differential equations, thereby enabling treatment of large problems involving both equilibrium and kinetically controlled reactions. Implications on the number of coupled partial differential equations necessary to be solved and on numerical algorithms for solving such problems are discussed. Examples provided illustrate the theory applied to solute transport in groundwater flow.

  7. Is Eurasian October snow cover extent increasing?

    International Nuclear Information System (INIS)

    Brown, R D; Derksen, C

    2013-01-01

    A number of recent studies present evidence of an increasing trend in Eurasian snow cover extent (SCE) in the October snow onset period based on analysis of the National Oceanic and Atmospheric Administration (NOAA) historical satellite record. These increases are inconsistent with fall season surface temperature warming trends across the region. Using four independent snow cover data sources (surface observations, two reanalyses, satellite passive microwave retrievals) we show that the increasing SCE is attributable to an internal trend in the NOAA CDR dataset to chart relatively more October snow cover extent over the dataset overlap period (1982–2005). Adjusting the series for this shift results in closer agreement with other independent datasets, stronger correlation with continentally-averaged air temperature anomalies, and a decrease in SCE over 1982–2011 consistent with surface air temperature warming trends over the same period.

    Deater-Deckard, Kirby; Sturge-Apple, Melissa L

    2017-02-01

    This is an introduction to the special section on neurobiological and neurocognitive factors in parenting. The collection of 11 papers are published in 2 serial subsections of consecutive issues of the journal. The science they present captures the leading edge of work examining the interface of cognitive, emotional, behavioral, and physiological self-regulation in parenting and how these operate to protect or increment risk for poorer parenting among families who face chronic stressors (e.g., poverty, single parenthood, homelessness, mood disorders). Samples span the poor to the affluent, many ethnicities, several nationalities, and a wide variety of geographic locations. The studies also are diverse in the methods employed, spanning behavioral and questionnaire indicators of executive function and effortful control, attentional and social-cognitive biases, and psychophysiology. Taken together, the papers present clear and compelling evidence for the crucial role of parental neurobiological and neurocognitive deficits and strengths in the etiology of distressed and resilient parenting.

  15. Spatial extent in demographic research - approach and problems

    Directory of Open Access Journals (Sweden)

    Knežević Aleksandar

    2015-01-01

    Full Text Available One of the starting methodological problems in demographic research is the definition of spatial extent, which mostly doesn’t correspond to spatial extent already defined by different levels of administrative-territorial unitsthat are used for distribution of usable statistical data. That’s why determining the spatial extent of a demographic research is closely tied with administrative-territorial division of the territory that is being researched, wherein the fact that differentiation of demographic phenomena and processes cannot be the only basis of setting the principles of regionalization must be strictly acknowledged. This problem is particularly common in historical demographic analyses of geographically determined wholes, which are in administratively-territorial sense represented by one or more smaller territorial units, with their borders changing through the history, which directly affects comparability of the statistical data, and makes it considerably more difficult to track demographic change through longer time intervals. The result of these efforts is usually a solution based on a compromise which enables us to examine the dynamics of population change with little deviation from already defined borders of regional geographic wholes. For that reason in this paper the problem of defining spatial extent in demographic research is examined trough several different approaches in case of Eastern Serbia, as a geographically determined region, a historic area, a spatially functioning whole and as a statistical unit for demographic research, with no judgment calls in regard to any of the regionalization principles.

  16. Introduction to safety theory

    International Nuclear Information System (INIS)

    Meyna, A.

    1982-01-01

    After a general introduction to safety theory, safety characteristics are defined and quantified. This is followed by a calculation of the safety characteristics of simple, safety-relevant systems in general and in consideration of common-mode errors. The qualitative and quantitative role of human errors is discussed for various models, and a simple man-machine model is developed for investigation of common-mode errors and human error. The main part of the paper deals with safety analysis in complex systems. After a general review, the common inductive and deductive methods of analysis are presented and commented on and their fields of application discussed. Analytical and simulation codes are presented as methods of evaluation for big, complex event trees - i.e. ''hazard trees in the sense of safety engineering (as a subset of safety relevance). After a basic classification and mathematical formulation of Markovian processes, the author shows that these may be used successfully for calculation of safety characteristics if transition rates are constant and if the number of system states is limited.

    Increasingly, jurisdictions are adopting universal assessment procedures and information technology to aid in healthcare data collection and care planning. Before their potential can be realised, a better understanding is needed of how these systems can best be used to support clinical practice. We investigated the decision-making process and information needs of home-care case managers in Ontario, Canada, prior to the widespread use of universal assessment, with a view of determining how universal assessment and information technology could best support this work. Three focus groups and two individual interviews were conducted; questioning focused on decision-making in the post-acute care of individuals recovering from a hip fracture. We found that case managers' decisional process was one of a clinician-broker, combining clinical expertise and information about local services to support patient goals within the context of limited resources. This process represented expert decision-making, and the case managers valued their ability to carry out non-standardised interviews and override system directives when they noted that data may be misleading. Clear information needs were found in four areas: services available outside of their regions, patient medical information, patient pre-morbid functional status and partner/spouse health and functional status. Implications for the use of universal assessment are discussed. Recommendations are made for further research to determine the impact of universal assessment and information technology on the process and outcome of home-care case manager decision-making.

    Economic evaluation is used for decision-making processes in healthcare technologies in many developed countries. In Japan, no health economic data have been requested for drugs, medical devices, and interventions till date. However, economic evaluation is gradually gaining importance, and a trial implementation of the cost-effectiveness evaluation of drugs and medical devices has begun. Discussions on economic evaluation began in May 2012 within a newly established sub-committee of the Chuikyo, referred to as the "Special Committee on Cost Effectiveness." After four years of discussions, this committee determined that during the trial implementation, the results of the cost-effectiveness evaluation would be used for the re-pricing of drugs and medical devices at the end of fiscal year (FY) 2017. Chuikyo selected 13 products (7 drugs and 6 medical devices) as targets for this evaluation. These products will be evaluated until the end of FY 2017 based on the following process: manufacturers will submit the data of economic evaluation; the National Institute of Public Health will coordinate the review process; academic groups will perform the actual review of the submitted data, and the expert committee will appraise these data. This represents the first step to introducing cost-effectiveness analysis in the Japanese healthcare system. We believe that these efforts will contribute to the efficiency and sustainability of the Japanese healthcare system. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

The improved observation capacity available if 50 m wide rivers are measured is important because natural and human processes often impact streamflow at scales smaller than 50,000 km2. Regardless, though, SWOT could likely match (in well-gauged areas at 100 m) or exceed (in less gauged areas) the spatial extent of the GRDC gauge network for basins larger than ~10,000 km2.

    2008-07-01

    The importance of the refining segment in the oil productive chain turns decision making on production and investment to be made at refineries dependent upon general context of the oil industry. Several technical and economic factors limit the possibilities to be foreseen by the managers. The ultimate goal of a refinery is to meet market demand in a region. Moreover, the type of processed oil and refining techniques will shape the profile of the production of derivatives. In a segment dynamic and full of uncertainties, such as refining, where the type of oil supplied to processing, specifications of products, and their demands, changes in the course of time, how to keep refining margins acceptable? This paper presents the relationship between the characteristics and the use of different kinds of oil, the characteristics of the national market of derivatives, and some characteristics of the refining processes considered in the study. The possible economic impacts that the introduction of different processes can bring to a refinery are analysed and alternatives for expansion are evaluated. To achieve these goals, a methodology for analysis considering the yield of Marlin oil refining for different schemes has been developed. (author)

  20. Overview: oxidant and particle photochemical processes above a south-east Asian tropical rainforest (the OP3 project: introduction, rationale, location characteristics and tools

    Directory of Open Access Journals (Sweden)

    C. N. Hewitt

    2010-01-01

    Full Text Available In April–July 2008, intensive measurements were made of atmospheric composition and chemistry in Sabah, Malaysia, as part of the "Oxidant and particle photochemical processes above a South-East Asian tropical rainforest" (OP3 project. Fluxes and concentrations of trace gases and particles were made from and above the rainforest canopy at the Bukit Atur Global Atmosphere Watch station and at the nearby Sabahmas oil palm plantation, using both ground-based and airborne measurements. Here, the measurement and modelling strategies used, the characteristics of the sites and an overview of data obtained are described. Composition measurements show that the rainforest site was not significantly impacted by anthropogenic pollution, and this is confirmed by satellite retrievals of NO2 and HCHO. The dominant modulators of atmospheric chemistry at the rainforest site were therefore emissions of BVOCs and soil emissions of reactive nitrogen oxides. At the observed BVOC:NOx volume mixing ratio (~100 pptv/pptv, current chemical models suggest that daytime maximum OH concentrations should be ca. 105 radicals cm−3, but observed OH concentrations were an order of magnitude greater than this. We confirm, therefore, previous measurements that suggest that an unexplained source of OH must exist above tropical rainforest and we continue to interrogate the data to find explanations for this.

    A substantial literature suggests that mobile phones have great potential to improve management and survival of acutely ill children in rural Africa. The national strategy of the Ugandan Ministry of Health calls for employment of volunteer community health workers (CHWs) in implementation of Integrated Community Case Management (iCCM) of common illnesses (diarrhea, acute respiratory infection, pneumonia, fever/malaria) affecting children under five years of age. A mobile phone enabled system was developed within iCCM aiming to improve access by CHWs to medical advice and to strengthen reporting of data on danger signs and symptoms for acutely ill children under five years of age. Herein critical steps in development, implementation, and integration of mobile phone technology within iCCM are described. Mechanisms to improve diagnosis, treatment and referral of sick children under five were defined. Treatment algorithms were developed by the project technical team and mounted and piloted on the mobile phones, using an iterative process involving technical support personnel, health care providers, and academic support. Using a purposefully developed mobile phone training manual, CHWs were trained over an intensive five-day course to make timely diagnoses, recognize clinical danger signs, communicate about referrals and initiate treatment with appropriate essential drugs. Performance by CHWs and the accuracy and completeness of their submitted data was closely monitored post training test period and during the subsequent nine month community trial. In the full trial, the number of referrals and correctly treated children, based on the agreed treatment algorithms, was recorded. Births, deaths, and medication stocks were also tracked. Seven distinct phases were required to develop a robust mobile phone enabled system in support of the iCCM program. Over a nine month period, 96 CHWs were trained to use mobile phones and their competence to initiate a community trial was

The first part contains proofs of the Abel-Jacobi theorem, Riemann's relations and the Lefschetz theorem on projective embeddings over the complex numbers in the spirit of S. Lang's book Introduction to algebraic and abelian functions. Then the Jacobians of Fermat curves as well as some modular curves are discussed. Finally, as an application, Faltings' proof of the Mordell conjecture and its intermediate steps, the Tate conjecture and the Shafarevich conjecture, are sketched. - H. Lange for MathSciNet.

  18. Introduction to Sporadic Groups

    Directory of Open Access Journals (Sweden)

    Luis J. Boya

    2011-01-01

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

  20. Mind a brief introduction

    CERN Document Server

    Searle, John R

    2004-01-01

    "The philosophy of mind is unique among contemporary philosophical subjects," writes John Searle, "in that all of the most famous and influential theories are false." One of the world's most eminent thinkers, Searle dismantles these theories as he presents a vividly written, comprehensive introduction to the mind. He begins with a look at the twelve problems of philosophy of mind--which he calls "Descartes and Other Disasters"--problems which he returns to throughout the volume, as he illuminates such topics as materialism, consciousness, the mind-body problem, intentionality, mental causation, free will, and the self. The book offers a refreshingly direct and engaging introduction to one of the most intriguing areas of philosophy.

  3. The extent of surgical patients' understanding.

    Pugliese, Omar Talhouk; Solari, Juan Lombardi; Ferreres, Alberto R

    2014-07-01

    The notion that consent to surgery must be informed implies not only that information should be provided by the surgeon but also that the information should be understood by the patient in order to give a foundation to his or her decision to accept or refuse treatment and thus, achieve autonomy for the patient. Nonetheless, this seems to be an idyllic situation, since most patients do not fully understand the facts offered and thus the process of surgical informed consent, as well as the patient's autonomy, may be jeopardized. Informed consent does not always mean rational consent.

  4. The extent and importance of intragenic recombination

    Directory of Open Access Journals (Sweden)

    de Silva Eric

    2004-11-01

    Full Text Available Abstract We have studied the recombination rate behaviour of a set of 140 genes which were investigated for their potential importance in inflammatory disease. Each gene was extensively sequenced in 24 individuals of African descent and 23 individuals of European descent, and the recombination process was studied separately in the two population samples. The results obtained from the two populations were highly correlated, suggesting that demographic bias does not affect our population genetic estimation procedure. We found evidence that levels of recombination correlate with levels of nucleotide diversity. High marker density allowed us to study recombination rate variation on a very fine spatial scale. We found that about 40 per cent of genes showed evidence of uniform recombination, while approximately 12 per cent of genes carried distinct signatures of recombination hotspots. On studying the locations of these hotspots, we found that they are not always confined to introns but can also stretch across exons. An investigation of the protein products of these genes suggested that recombination hotspots can sometimes separate exons belonging to different protein domains; however, this occurs much less frequently than might be expected based on evolutionary studies into the origins of recombination. This suggests that evolutionary analysis of the recombination process is greatly aided by considering nucleotide sequences and protein products jointly.

  5. A Global Geospatial Database of 5000+ Historic Flood Event Extents

    A key dataset that is missing for global flood model validation and understanding historic spatial flood vulnerability is a global historical geo-database of flood event extents. Decades of earth observing satellites and cloud computing now make it possible to not only detect floods in near real time, but to run these water detection algorithms back in time to capture the spatial extent of large numbers of specific events. This talk will show results from the largest global historical flood database developed to date. We use the Dartmouth Flood Observatory flood catalogue to map over 5000 floods (from 1985-2017) using MODIS, Landsat, and Sentinel-1 Satellites. All events are available for public download via the Earth Engine Catalogue and via a website that allows the user to query floods by area or date, assess population exposure trends over time, and download flood extents in geospatial format.In this talk, we will highlight major trends in global flood exposure per continent, land use type, and eco-region. We will also make suggestions how to use this dataset in conjunction with other global sets to i) validate global flood models, ii) assess the potential role of climatic change in flood exposure iii) understand how urbanization and other land change processes may influence spatial flood exposure iv) assess how innovative flood interventions (e.g. wetland restoration) influence flood patterns v) control for event magnitude to assess the role of social vulnerability and damage assessment vi) aid in rapid probabilistic risk assessment to enable microinsurance markets. Authors on this paper are already using the database for the later three applications and will show examples of wetland intervention analysis in Argentina, social vulnerability analysis in the USA, and micro insurance in India.

  7. An introduction to computer forensics.

    Furneaux, Nick

    2006-07-01

    This paper provides an introduction to the discipline of Computer Forensics. With computers being involved in an increasing number, and type, of crimes the trace data left on electronic media can play a vital part in the legal process. To ensure acceptance by the courts, accepted processes and procedures have to be adopted and demonstrated which are not dissimilar to the issues surrounding traditional forensic investigations. This paper provides a straightforward overview of the three steps involved in the examination of digital media: Acquisition of data. Investigation of evidence. Reporting and presentation of evidence. Although many of the traditional readers of Medicine, Science and the Law are those involved in the biological aspects of forensics, I believe that both disciplines can learn from each other, with electronic evidence being more readily sought and considered by the legal community and the long, tried and tested scientific methods of the forensic community being shared and adopted by the computer forensic world.

  10. Corticocortical feedback increases the spatial extent of normalization.

    Nassi, Jonathan J; Gómez-Laberge, Camille; Kreiman, Gabriel; Born, Richard T

    2014-01-01

    Normalization has been proposed as a canonical computation operating across different brain regions, sensory modalities, and species. It provides a good phenomenological description of non-linear response properties in primary visual cortex (V1), including the contrast response function and surround suppression. Despite its widespread application throughout the visual system, the underlying neural mechanisms remain largely unknown. We recently observed that corticocortical feedback contributes to surround suppression in V1, raising the possibility that feedback acts through normalization. To test this idea, we characterized area summation and contrast response properties in V1 with and without feedback from V2 and V3 in alert macaques and applied a standard normalization model to the data. Area summation properties were well explained by a form of divisive normalization, which computes the ratio between a neuron's driving input and the spatially integrated activity of a "normalization pool." Feedback inactivation reduced surround suppression by shrinking the spatial extent of the normalization pool. This effect was independent of the gain modulation thought to mediate the influence of contrast on area summation, which remained intact during feedback inactivation. Contrast sensitivity within the receptive field center was also unaffected by feedback inactivation, providing further evidence that feedback participates in normalization independent of the circuit mechanisms involved in modulating contrast gain and saturation. These results suggest that corticocortical feedback contributes to surround suppression by increasing the visuotopic extent of normalization and, via this mechanism, feedback can play a critical role in contextual information processing.

    During eutectoid transformation of U-10Mo alloy, uniform metastable γ UMo phase is expected to transform to a mixture of α-U and γ’-U2Mo phase. The presence of transformation products in final U-10Mo fuel, especially the α phase is considered detrimental for fuel irradiation performance, so it is critical to accurately evaluate the extent of transformation in the final U-10Mo alloy. This phase transformation can cause a volume change that induces a density change in final alloy. To understand this density and volume change, we developed a theoretical model to calculate the volume expansion and resultant density change of U-10Mo alloy as a function of the extent of eutectoid transformation. Based on the theoretically calculated density change for 0 to 100% transformation, we conclude that an experimental density measurement system will be challenging to employ to reliably detect and quantify the extent of transformation. Subsequently, to assess the ability of various methods to detect the transformation in U-10Mo, we annealed U-10Mo alloy samples at 500°C for various times to achieve in low, medium, and high extent of transformation. After the heat treatment at 500°C, the samples were metallographically polished and subjected to optical microscopy and x-ray diffraction (XRD) methods. Based on our assessment, optical microscopy and image processing can be used to determine the transformed area fraction, which can then be correlated with the α phase volume fraction measured by XRD analysis. XRD analysis of U-10Mo aged at 500°C detected only α phase and no γ’ was detected. To further validate the XRD results, atom probe tomography (APT) was used to understand the composition of transformed regions in U-10Mo alloys aged at 500°C for 10 hours. Based on the APT results, the lamellar transformation product was found to comprise α phase with close to 0 at% Mo and γ phase with 28–32 at% Mo, and the Mo concentration was highest at the

    During eutectoid transformation of U-10Mo alloy, uniform metastable ? UMo phase is expected to transform to a mixture of ?-U and ?'-U_2Mo phase.

After the heat treatment at 500°C, the samples were metallographically polished and subjected to optical microscopy and x-ray diffraction (XRD) methods. Based on our assessment, optical microscopy and image processing can be used to determine the transformed area fraction, which can then be correlated with the ? phase volume fraction measured by XRD analysis. XRD analysis of U-10Mo aged at 500°C detected only ? phase and no ?' was detected. To further validate the XRD results, atom probe tomography (APT) was used to understand the composition of transformed regions in U-10Mo alloys aged at 500°C for 10 hours. Based on the APT results, the lamellar transformation product was found to comprise ? phase with close to 0 at% Mo and ? phase with 28-32 at% Mo, and the Mo concentration was highest at the ?/? interface.

  11. Space charge sign inversion and electric field reconstruction in 24 GeV/c proton-irradiated MCZ Si p+-n(TD)-n+ detectors processed via thermal donor introduction

    Li, Z.; Verbitskaya, E.; Carini, G.; Chen, W.; Eremin, V.; Gul, R.; Haerkoenen, J.; Li, M.

    2009-01-01

    The aim of this study is the evaluation of radiation effects in detectors based on p-type magnetic czochralski (MCZ) Si that was converted to n-type by thermal donor (TD) introduction. As-processed p + -p-n + detectors were annealed at 430 deg. C resulting in p + -n(TD)-n + structures. The space charge sign and the electric field distribution E(x) in MCz Si p + -n(TD)-n + detectors irradiated by 24 GeV/c protons were analyzed using the data on the current pulse response and the Double Peak (DP) electric field distribution model for heavily irradiated detectors. The approach considers an irradiated detector as a structure with three regions in which the electric field depends on the coordinate, and the induced current pulse response arises from the drift process of free carriers in the detector with variable electric field. Reconstruction of the E(x) profile from the pulse response shapes is performed employing a new method for DP electric field reconstruction. This method includes: (a) a direct extraction of charge loss due to trapping and (b) the fitting of a simulated pulse response to the 'corrected' pulse by adjusting the electric field profiles in the three regions. Reconstruction of E(x) distribution showed that in the diodes irradiated by a proton fluence of (2-4)x10 14 p/cm 2 space charge sign inversion has occurred. This is the evidence that the influence of 24 GeV/c proton radiation on MCz Si p + -n(TD)-n + detectors is similar to that on p + -n-n + detectors based on FZ or diffusion oxygenated n-type Si.

  12. Infinity a very short introduction

    CERN Document Server

    Stewart, Ian

    2017-01-01

    Infinity is an intriguing topic, with connections to religion, philosophy, metaphysics, logic, and physics as well as mathematics. Its history goes back to ancient times, with especially important contributions from Euclid, Aristotle, Eudoxus, and Archimedes. The infinitely large (infinite) is intimately related to the infinitely small (infinitesimal). Cosmologists consider sweeping questions about whether space and time are infinite. Philosophers and mathematicians ranging from Zeno to Russell have posed numerous paradoxes about infinity and infinitesimals. Many vital areas of mathematics rest upon some version of infinity. The most obvious, and the first context in which major new techniques depended on formulating infinite processes, is calculus. But there are many others, for example Fourier analysis and fractals. In this Very Short Introduction, Ian Stewart discusses infinity in mathematics while also drawing in the various other aspects of infinity and explaining some of the major problems and insights ...

    Science.gov (United States)

    Chrysanthis, Panos K.

    1996-12-01

    Computer Science Department, University of Pittsburgh, Pittsburgh, PA 15260, USA This special issue focuses on current efforts to represent and support workflows that integrate information systems and human resources within a business or manufacturing enterprise. Workflows may also be viewed as an emerging computational paradigm for effective structuring of cooperative applications involving human users and access to diverse data types not necessarily maintained by traditional database management systems. A workflow is an automated organizational process (also called business process) which consists of a set of activities or tasks that need to be executed in a particular controlled order over a combination of heterogeneous database systems and legacy systems. Within workflows, tasks are performed cooperatively by either human or computational agents in accordance with their roles in the organizational hierarchy. The challenge in facilitating the implementation of workflows lies in developing efficient workflow management systems. A workflow management system (also called workflow server, workflow engine or workflow enactment system) provides the necessary interfaces for coordination and communication among human and computational agents to execute the tasks involved in a workflow and controls the execution orderings of tasks as well as the flow of data that these tasks manipulate. That is, the workflow management system is responsible for correctly and reliably supporting the specification, execution, and monitoring of workflows. The six papers selected (out of the twenty-seven submitted for this special issue of Distributed Systems Engineering) address different aspects of these three functional components of a workflow management system. In the first paper, `Correctness issues in workflow management', Kamath and Ramamritham discuss the important issue of correctness in workflow management that constitutes a prerequisite for the use of workflows in the automation

  15. Gibbon Aggression During Introductions: An International Survey.

    Harl, Heather; Stevens, Lisa; Margulis, Susan W; Petersen, Jay

    2016-01-01

    Little is known regarding the prevalence of aggression seen during introductions of captive gibbons (Hylobatidae). In this study, an online survey was developed to quantify and collect contextual details regarding the frequency and types of aggression seen during introductions of captive gibbons (Hylobatidae). Nineteen percent of institutions (17 institutions) reported observing aggression, and 6 of these institutions recorded multiple instances of aggression, though a vast majority of these cases resulted in mild injuries or none at all. The female was the primary aggressor in 23% of cases, the male was the primary aggressor in 58% of cases, and both were the primary aggressor in 1 case. Although these aggressive interactions were often not associated with a known cause, 27% of cases were associated with food displacement. In most cases, management changes, including trying new pairings, greatly reduced situational aggression, suggesting that individual personalities may play a factor in aggression. These data begin to explain the extent of aggression observed in captive gibbons; future studies will address possible correlations with aggression and introduction techniques.

  16. Morbillivirus Infections: An Introduction

    Directory of Open Access Journals (Sweden)

    Rory D. de Vries

    2015-02-01

    Full Text Available Research on morbillivirus infections has led to exciting developments in recent years. Global measles vaccination coverage has increased, resulting in a significant reduction in measles mortality. In 2011 rinderpest virus was declared globally eradicated – only the second virus to be eradicated by targeted vaccination. Identification of new cellular receptors and implementation of recombinant viruses expressing fluorescent proteins in a range of model systems have provided fundamental new insights into the pathogenesis of morbilliviruses, and their interactions with the host immune system. Nevertheless, both new and well-studied morbilliviruses are associated with significant disease in wildlife and domestic animals. This illustrates the need for robust surveillance and a strategic focus on barriers that restrict cross-species transmission. Recent and ongoing measles outbreaks also demonstrate that maintenance of high vaccination coverage for these highly infectious agents is critical. This introduction briefly summarizes the most important current research topics in this field.

    Full Text Available Ethics is becoming one of the most often used but also misinter­preted words. It is often taken as an additional, corrective parameter to the policies and strategies that has to be adopted in the area of political works, environment, business, and medicine. Computer ethics thus makes the latest ethical discipline in the scientific sky. But its roots, as it was the case with environmental ethics, ranging decades; only the speech and the use of the same, as well as discussions on the postulates of computer ethics, are the results of rapid IT development in the last decade or two. In this paper, according to the title, will be shown introduction to computer ethics-its basis, the most important representatives, as well as the most important succession.

  2. Introduction to thermoelectricity

    CERN Document Server

    Goldsmid, H Julian

    2016-01-01

    This book is a comprehensive introduction to all aspects of thermoelectric energy conversion. It covers both theory and practice. The book is timely as it refers to the many improvements that have come about in the last few years through the use of nanostructures. The concept of semiconductor thermoelements led to major advances during the second half of the twentieth century, making Peltier refrigeration a widely used technique. The latest materials herald thermoelectric generation as the preferred technique for exploiting low-grade heat. The book shows how progress has been made by increasing the thermal resistivity of the lattice until it is almost as large as it is for glass. It points the way towards the attainment of similar improvements in the electronic parameters. It does not neglect practical considerations, such as the desirability of making thermocouples from inexpensive and environmentally acceptable materials. The second edition was extended to also include recent advances in thermoelectric ener...

    International Nuclear Information System (INIS)

    Miranda, E.

    2003-01-01

    This is a pedagogical introduction to the general technique of bosonization of one-dimensional systems starting from scratch and assuming very little besides basic quantum mechanics and second quantization. The formalism is developed in a self-contained fashion and applied to the spinless and spin-1/2 Luttinger models, working out both single and two particle correlation functions. The implications of these results for the specific cases of the (anisotropic) Heisenberg and the Hubbard models are discussed. Although everything in these notes can be found in the published literature, detailed and explicit calculations of most of the results are given, which may prove useful to beginning graduate students or researchers in this area.

  5. Introduction to complex plasmas

    International Nuclear Information System (INIS)

    Bonitz, Michael; Ludwig, Patrick; Horing, Norman

    2010-01-01

    Complex plasmas differ from traditional plasmas in many ways: these are low-temperature high pressure systems containing nanometer to micrometer size particles which may be highly charged and strongly interacting. The particles may be chemically reacting or be in contact with solid surfaces, and the electrons may show quantum behaviour. These interesting properties have led to many applications of complex plasmas in technology, medicine and science. Yet complex plasmas are extremely complicated, both experimentally and theoretically, and require a variety of new approaches which go beyond standard plasma physics courses. This book fills this gap presenting an introduction to theory, experiment and computer simulation in this field. Based on tutorial lectures at a very successful recent Summer Institute, the presentation is ideally suited for graduate students, plasma physicists and experienced undergraduates. (orig.)

    2011-01-01

    Solid waste management is as old as human civilization, although only considered an engineering discipline for about one century. The change from the previous focus on public cleansing of the cities to modern waste management was primarily driven by industrialization, which introduced new materials...... and chemicals, dramatically changing the types and composition of waste, and by urbanization making waste management in urban areas a complicated and costly logistic operation. This book focuses on waste that commonly appears in the municipal waste management system. This chapter gives an introduction to modern...... waste management, including issues as waste definition, problems associated with waste, waste management criteria and approaches to waste management. Later chapters introduce aspects of engineering (Chapter 1.2), economics (Chapter 1.3) and regulation (Chapter 1.4)....

  12. Introduction to representation theory

    CERN Document Server

    Etingof, Pavel; Hensel, Sebastian; Liu, Tiankai; Schwendner, Alex

    2011-01-01

    Very roughly speaking, representation theory studies symmetry in linear spaces. It is a beautiful mathematical subject which has many applications, ranging from number theory and combinatorics to geometry, probability theory, quantum mechanics, and quantum field theory. The goal of this book is to give a "holistic" introduction to representation theory, presenting it as a unified subject which studies representations of associative algebras and treating the representation theories of groups, Lie algebras, and quivers as special cases. Using this approach, the book covers a number of standard topics in the representation theories of these structures. Theoretical material in the book is supplemented by many problems and exercises which touch upon a lot of additional topics; the more difficult exercises are provided with hints. The book is designed as a textbook for advanced undergraduate and beginning graduate students. It should be accessible to students with a strong background in linear algebra and a basic k...

  14. Introduction to supergravity

    CERN Document Server

    Tanii, Yoshiaki

    2014-01-01

    This book is a pedagogical introduction to supergravity, a gravitational field theory that includes supersymmetry (symmetry between bosons and fermions) and is a generalization of Einstein's general relativity. Supergravity provides a low-energy effective theory of superstring theory, which has attracted much attention as a candidate for the unified theory of fundamental particles, and it is a useful tool for studying non-perturbative properties of superstring theory such as D-branes and string duality. This work considers classical supergravities in four and higher spacetime dimensions with their applications to superstring theory in mind. More concretely, it discusses classical Lagrangians (or field equations) and symmetry properties of supergravities. Besides local symmetries, supergravities often have global non-compact symmetries, which play a crucial role in their applications to superstring theory. One of the main features of this book is its detailed discussion of these non-compact symmetries. The aim...

  15. History and General Introduction

    International Nuclear Information System (INIS)

    Dunbar, R.C.

    1991-01-01

    In the domain of analytical mass spectrometry (MS), FT-ICR's place is established as combining particular advantages of extraordinary mass resolution and accuracy, a wide array of sample-ionization techniques, and a uniquely wide range of methods for structure characterization of the primary sample ions. Costs are already attractive compared with other high-performance alternatives, and as both magnets and computers (which comprise much of the expense of FT-ICR hardware) become cheaper and more powerful, the performance/cost ratio for the technique will continue to improve. This paper will provide an introduction to those who have little previous knowledge of the technique; provide an overview of the technique's outstanding areas of scientific and analytical application; and provide some historical perspective on how we reached the present state of the art

  17. Introduction to tropical geometry

    CERN Document Server

    Maclagan, Diane

    2015-01-01

    Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of t...

    2016-01-01

    INTRODUCTION TO GENERAL RELATIVITY begins with a description of the geometry of curved space, explaining geodesics, parallel transport, covariant differentiation, geodesic deviation and spacetime symmetry by killing vectors. It then introduces Einstein's theory of gravitation followed by Schwarzschild solution with its relevance to Positive Mass theorem. The three tests for Einstein's gravity are explained. Other exact solutions such as Vaidya, Kerr and Reisner - Nordstrom metric are included. In the Chapter on cosmological solutions, a detailed description of Godel metric is provided. It then introduces five dimensional spacetime of Kaluza showing the unification of gravity with electromagnetism. This is extended to include non-Abelian gauge theory by invoking compact extra dimensions. Explicit expressions in this case for Christoffel connections and ricci tensor are derived and the higher dimensional gravity action is shown to compactification are given.

    Mattos, O.A. de.

    1986-01-01

    In the present work, supersymmetry is motivated via the Coleman-Mandula Theorem. Next, we build SUSY' algebra and representations (particularly, field representation). We then introduce the conceots of superspace and superfield, as well as supermultiplets and their invariants. Our next step is to examine simple models, in order to study auxiliary fields and the off-shell representations, to calculate the super-current and to show with super-graphs the loops cancelation (Wess-Zumino) and SUSY breaking (O'Raifeartaigh). Next, we obtain the supersymetric extension of the QED Lagrangean in to different ways, and them we are able to investigate symmetry breaking in supersymmetric gauge theories, and the appearance of Goldstone fermions. Finally, we study n-extended SUSY and the role of central charges, and examine SUSY in d > 4 dimensions and dimensional reduction. We end up with an introduction to Lie groups. (author) [pt

  2. Introduction to special relativity

    International Nuclear Information System (INIS)

    Rindler, W.

    1982-01-01

    This is intended as a text for an introductory course on special relativity; it assumes no prior knowledge of relativity. It is intended for the upper undergraduate level and upwards. The first three chapters take a three-dimensional viewpoint for a simple introduction to topics such as the relativity of simultaneity, length contraction, time dilation, the twin paradox and the appearance of moving objects. For the remaining chapters the strongest possible use is made of four-dimensional techniques. Chapter four deals with space-time, chapters five and six with mechanics and electromagnetism. In these a purely synthetic four-tensor approach is adopted. Pure tensor theory is covered in an appendix. The last chapter is on the mechanics of continua. (U.K.)

  4. Introduction to singularities

    CERN Document Server

    Ishii, Shihoko

    2014-01-01

    This book is an introduction to singularities for graduate students and researchers. It is said that algebraic geometry originated in the seventeenth century with the famous work Discours de la méthode pour bien conduire sa raison, et chercher la vérité dans les sciences by Descartes. In that book he introduced coordinates to the study of geometry. After its publication, research on algebraic varieties developed steadily. Many beautiful results emerged in mathematicians’ works. Most of them were about non-singular varieties. Singularities were considered “bad” objects that interfered with knowledge of the structure of an algebraic variety. In the past three decades, however, it has become clear that singularities are necessary for us to have a good description of the framework of varieties. For example, it is impossible to formulate minimal model theory for higher-dimensional cases without singularities. Another example is that the moduli spaces of varieties have natural compactification, the boundar...

  5. Introduction to multivariate discrimination

    Kégl, Balázs

    2013-07-01

    Multivariate discrimination or classification is one of the best-studied problem in machine learning, with a plethora of well-tested and well-performing algorithms. There are also several good general textbooks [1-9] on the subject written to an average engineering, computer science, or statistics graduate student; most of them are also accessible for an average physics student with some background on computer science and statistics. Hence, instead of writing a generic introduction, we concentrate here on relating the subject to a practitioner experimental physicist. After a short introduction on the basic setup (Section 1) we delve into the practical issues of complexity regularization, model selection, and hyperparameter optimization (Section 2), since it is this step that makes high-complexity non-parametric fitting so different from low-dimensional parametric fitting. To emphasize that this issue is not restricted to classification, we illustrate the concept on a low-dimensional but non-parametric regression example (Section 2.1). Section 3 describes the common algorithmic-statistical formal framework that unifies the main families of multivariate classification algorithms. We explain here the large-margin principle that partly explains why these algorithms work. Section 4 is devoted to the description of the three main (families of) classification algorithms, neural networks, the support vector machine, and AdaBoost. We do not go into the algorithmic details; the goal is to give an overview on the form of the functions these methods learn and on the objective functions they optimize. Besides their technical description, we also make an attempt to put these algorithm into a socio-historical context. We then briefly describe some rather heterogeneous applications to illustrate the pattern recognition pipeline and to show how widespread the use of these methods is (Section 5). We conclude the chapter with three essentially open research problems that are either

    The organization of a distributed system can have a tremendous impact on its capabilities, its performance, and its ability to evolve to meet changing requirements. For example, the client - server organization model has proven to be adequate for organizing a distributed system as a number of distributed servers that offer various functions to client processes across the network. However, it lacks peer-to-peer capabilities, and experience with the model has been predominantly in the context of local networks. To achieve peer-to-peer cooperation in a more global context, systems issues of scale, heterogeneity, configuration management, accounting and sharing are crucial, and the complexity of migrating from locally distributed to more global systems demands new tools and techniques. An emphasis on interfaces and modules leads to the modelling of a complex distributed system as a collection of interacting objects that communicate with each other only using requests sent to well defined interfaces. Although object granularity typically varies at different levels of a system architecture, the same object abstraction can be applied to various levels of a computing architecture. Since 1989, the Object Management Group (OMG), an international software consortium, has been defining an architecture for distributed object systems called the Object Management Architecture (OMA). At the core of the OMA is a `software bus' called an Object Request Broker (ORB), which is specified by the OMG Common Object Request Broker Architecture (CORBA) specification. The OMA distributed object model fits the structure of heterogeneous distributed applications, and is applied in all layers of the OMA. For example, each of the OMG Object Services, such as the OMG Naming Service, is structured as a set of distributed objects that communicate using the ORB. Similarly, higher-level OMA components such as Common Facilities and Domain Interfaces are also organized as distributed objects that can

    1974-01-01

    Radar, Sonar, and Holography: An Introduction provides an introduction to the technology of radar and sonar. Because the new science of holography is affecting both these fields quite strongly, the book includes an explanation of the fundamental principles underlying this new art (including the subjects of wave coherence, interference, and diffraction) and of the hologram process itself. Finally, numerous examples are discussed which show how holography is providing new horizons to radar and sonar systems. The book thus also provides a simple approach to the new technology of holography. The

  10. Introduction to Special Issue on Transience

    Lønsmann, Dorte; Haberland, Hartmut; Hazel, Spencer

    2017-01-01

    In this introduction to the special issue, the concept of transience is introduced as a theoretical perspective and as an object of research. The perspective of transience foregrounds the temporality of norm formation, located within the practices of people on the move. The introduction suggests......, as it is in the process of communities coming into being that norms emerge. Transience, in spite of being ubiquitous, is not always salient for members or analysts, but to identify, fixate and theorize it as an object of study in linguistic anthropology invites new ways of conceptualizing the interdependence of language...

    Quality of Service (QoS) has emerged in the last few years as a topical and challenging research area in distributed systems. For a broad definition of QoS we refer to the ISO's Reference Model for Open Distributed Processing (ISO/IEC IS 10746-2): `The notion of QoS is a system or object property, and consists of a set of quality requirements on the collective behaviour of one or more objects . . .'. In the context of this special issue, QoS is primarily associated with systems such as distributed multimedia application platforms or distributed simulations. The QoS requirements of such systems typically relate to measures of rate and latency of information transfer, probability of a communication being disrupted, probability of system failure, probability of storage failure, etc. The role of QoS management is thus to ensure that applications are able to specify and obtain the quality of service that they require for their correct execution. In general, the functions of QoS management may be subsumed under the following headings: (i) QoS specification and mapping, (ii) QoS negotiation, resource allocation and admission control and (iii) QoS monitoring, adaptation and renegotiation. QoS specification defines the QoS required by an application in terms of both timeliness constraints and guarantees. QoS mapping then translates between QoS representations at different system levels, relieving the user of the necessity of thinking in terms of low-level QoS representations. For example, a user may express a jitter requirement by manipulating a slider in a GUI, and this could be mapped at the lower layers into a requirement for an absolute bound on ATM cell jitter and a jitter smoothing buffer of a certain size. QoS negotiation, resource allocation and admission control are collectively responsible for configuring a system in preparation for the execution of a QoS requiring application. QoS negotiation provides a framework in which the QoS levels supported by individual

    Full Text Available (from the introduction Intuition and affect have been neglected topics in the literature on human judgment and decision making for a long time. Judgmental processes involved in risk perception and decision making have traditionally been conceptualized as cognitive in nature, being based upon a rational and deliberate evaluation of the alternatives at hand. This picture started to change in the early 1980s when decision researchers looked beyond rational, deliberate, and cognitive processes and began to investigate intuitive --- as opposed to deliberate --- and emotional --- as opposed to cognitive --- aspects of decision making. In sum, decision research has seen a proliferation of approaches that look beyond rational, deliberate, and purely cognitive processes in decision making and investigate intuitive and emotional judgments in this area. This seemed like a good point in time to reflect the state of this emerging field in a special issue that addresses the question of how intuition and affect are related to each other and how they shape risk perception and decision making. This special issue is the result of a workshop that was held at the University of Bergen in November, 2006.

  15. Evolutionary history, immigration history, and the extent of diversification in community assembly.

    Science.gov (United States)

    Knope, Matthew L; Forde, Samantha E; Fukami, Tadashi

    2011-01-01

    During community assembly, species may accumulate not only by immigration, but also by in situ diversification. Diversification has intrigued biologists because its extent varies even among closely related lineages under similar ecological conditions. Recent research has suggested that some of this puzzling variation may be caused by stochastic differences in the history of immigration (relative timing and order of immigration by founding populations), indicating that immigration and diversification may affect community assembly interactively. However, the conditions under which immigration history affects diversification remain unclear. Here we propose the hypothesis that whether or not immigration history influences the extent of diversification depends on the founding populations' prior evolutionary history, using evidence from a bacterial experiment. To create genotypes with different evolutionary histories, replicate populations of Pseudomonas fluorescens were allowed to adapt to a novel environment for a short or long period of time (approximately 10 or 100 bacterial generations) with or without exploiters (viral parasites). Each evolved genotype was then introduced to a new habitat either before or after a standard competitor genotype. Most genotypes diversified to a greater extent when introduced before, rather than after, the competitor. However, introduction order did not affect the extent of diversification when the evolved genotype had previously adapted to the environment for a long period of time without exploiters. Diversification of these populations was low regardless of introduction order. These results suggest that the importance of immigration history in diversification can be predicted by the immigrants' evolutionary past. The hypothesis proposed here may be generally applicable in both micro- and macro-organisms.

  16. Introduction: Exile and Social Transformation

    Directory of Open Access Journals (Sweden)

    Paul Allatson

    2005-03-01

    Full Text Available This paper serves as an introduction to the special issue of Portal on exile and its potential to effect social change. The critical and creative discussions that follow this introduction respond to a particular set of problems. What factors permit and preclude exilic individual and communal transformation? Is there a need to rethink exilic agency in accord with local times, cultures and places, and to refocus attention on exile communal impacts on a host society? And, in a globalized epoch characterized by mass population movements across geopolitical lines, do states and national desires still have key roles to play in the production of exile? There are no straightforward answers to these questions, but all gesture toward the inadequacy of a single overarching definition or description of exile. Indeed, the process of exile has generated a great deal of debate regarding to whom the term exile applies and when. Furthermore, a number of unresolved issues recur in the extensive literature on the topic: the problematic location of exile and its definitional dependency on a home or homeland; the multivalent struggles to attain and maintain exilic voice, representation, memory, and identity on many fronts (individual, familial, communal, national, transnational; exile’s uneasy relation to modernity, the state, and globalization; and exile’s conceptual competition with other terms, such as diaspora, exodus, refugee and migrant. Intended as a selective reprise of these issues and the ways the contributors to this issue have responded to them, this introduction identifies some of the claims that have been made of exile as a space or mode of social transformation, as well as the possible limits of such claims.

  20. Introduction to anomalies

    International Nuclear Information System (INIS)

    Alvarez-Gaume, L.

    1986-01-01

    These lectures are dedicated to the study of the recent progress and implications of anomalies in quantum field theory. In this introduction the author recapitulates some of the highlights in the history of the subject. The outline of these lectures is as follows: Section II contains a quick review of spinors in Euclidean and Minkowski space, some other group theory results relevant for the computation of anomalies in various dimensions, and an exposition of the index theorem. Section III starts the analysis of fermion determinants and chiral effective actions by deriving the non-Abelian anomaly from index theory. Using the results of Section II, the anomaly cancellation recently discovered by Green and Schwarz will be presented in Section IV as well as the connection of these results of Section III with the descent equations and the Wess-Zumino-Witten Lagrangians. Section V contains the generalization of anomalies to σ-models and some of its application in string theory. Section VI will deal with the anomalies from the Hamiltonian point of view. An exact formula for the imaginary part of the effective action for chiral fermions in the presence of arbitrary external gauge and gravitational fields will be derived in Section VII, and used in Section VIII for the study of global anomalies. 85 references

  2. Introduction: Childhood and Disability.

    Salter, Erica K

    2017-09-01

    From growth attenuation therapy for severely developmentally disabled children to the post-natal management of infants with trisomy 13 and 18, pediatric treatment decisions regularly involve assessments of the probability and severity of a child's disability. Because these decisions are almost always made by surrogate decision-makers (parents and caregivers) and because these decision-makers must often make decisions based on both prognostic guesses and potentially biased quality of life judgments, they are among the most ethically complex in pediatric care. As the introduction to HEC Forum's special thematic issue on Childhood and Disability, this article orients the reader to the history of bioethics' relationship to both pediatric ethics and disability studies and introduces the issue's five manuscripts. As clinicians, disability scholars, philosophers and clinical ethicists writing on various aspects of pediatric disability, the articles' authors all invite readers to dig beneath an overly-simplified version of what disability might mean to children and families and instead embrace a posture of genuine humility, recognizing both the limits and harms of traditional medical and bioethical responses (or indifferences) to the disabled child.

  4. Introduction to supersymmetry

    International Nuclear Information System (INIS)

    Schreiber, G.U.

    1987-09-01

    The Dirac equation as a relativistic quantum mechanical equation describing spin-half particles in higher-dimensional space-time is discussed. Clifford algebra in d-dimensional space-time is considered. Also discussed are the discrete symmetries of the Dirac equation, namely: charge conjunction, time reversal and parity or reflection symmetry. The Majorana and Weyl conditions which require the particle wavefunctions to be invariant under particle ↔ antiparticle exchange and left-handed particle ↔ right-handed antiparticle exchange respectively, are investigated. The Poincare group, consisting of the Lorentz group of space rotations, Lorentz boosts and the group of space-time translations, is examined, along with its irreducible representations. The concept of supersymmetry arises out of the generalisation of Lie algebras. An introduction to supersymmetry, as well as the immediate consequences of supersymmetry algebra, is given. Finally, the superspace-superfield approach is introduced. Superspace is a mathematical object which allows a simplification of the formulation of supersymmetry. The advantage of this formulation is that now supersymmetry becomes manifest: it arises naturally just like the Poincare symmetry arises naturally in four-dimensional Minkowski space. 46 refs., 9 figs., 23 tabs

    For the first topic in this book, more on introduction to nondestructive testing, also a little bit on another technique such as magnetic testing, liquid penetrated, ultrasonic testing and others. This book mentions more on radiographic testing and for that, more details on this topic such as history, definition and devices that use in this technique. This radiography testing firstly started with the discovering of x-ray by Wilhelm Roentgen (1895). So, on 1913, David Coolidge successfully invented and developed x-ray tube that could made x-ray more intensified and produced highly penetration forces. Radiography in Malaysia firstly started two years after the discovery made by Wilhelm Roentgen when one hospital here used the x-ray machine for medical purposes. Besides using x-ray, radiography also used gamma rays, and for these purpose, they used Co-60 and Ir-192. Now, more company based on NDT established to provide a service on inspection pipe and others. For filled these requirement, radiographer must take an exam to make them expert and trained well to work in this field. There is no advantage using this technique or other technique. So that's why this book was published to make people understand what is radiographic testing truly.

  7. Women and AIDS: introduction.

    Krieger, N; Margo, G

    1991-01-01

    Around the world, more and more women--principally poor women of color--are being diagnosed with and are dying of AIDS, the acquired immune deficiency syndrome. Yet, effective and appropriate prevention programs for women are sorely missing from the global program to control AIDS. To help us understand why this gap exists, and what we must do to close it, the three articles in this issue focus on women and AIDS. Examining the situation in such countries as Zimbabwe and South Africa, as well as in other economically underdeveloped and developed regions, the authors argue that women with the least control over their bodies and their lives are at greatest risk of acquiring AIDS. For example, the high rate of infection among women in Africa cannot be understood apart from the legacy of colonialism (including land expropriation and the forced introduction of a migrant labor system) and the insidious combination of traditional and European patriarchal values. Only by recognizing the socioeconomic and cultural determinants of both disease and sexual behavior, and only by incorporating these insights into our AIDS prevention programs, will we be able to curb the spread of this lethal disease.

  10. Introduction: Victorian Theatricalities

    Directory of Open Access Journals (Sweden)

    Michael Dobson

    2009-04-01

    Full Text Available After a barrage of manipulative fan-letters from Sir Merton and Annie Russell-Cotes, Sir Henry Irving, titan of the Victorian stage and the first actor to be knighted, eventually came to stay, briefly, at East Cliff Hall in Bournemouth. A peculiar but attractive compound of Scots baronial castle, Italian villa, French château and Bournemouth seaside bungalow, complete with lavish Art Nouveau interiors and a fountain in the entrance lobby, the house was always designed in and of itself as a dramatic location and was also intended as a magnet for theatrical celebrities. Sir Merton and Annie amply stuffed it with nineteenth-century British paintings, miscellaneous sculptures, and souvenirs of their extensive overseas holidays. Today the Russell-Cotes Art Gallery and Museum remains the late Victorian treasure house par excellence, and I can imagine few more vivid short-cuts into the culture and mindset of the late nineteenth-century haute bourgeoisie than an afternoon spent marvelling at the tons of accumulated trophies and bibelots cluttering its rooms or the acres of tastefully-exposed nipples adorning its walls. What the Russell-Cotes Museum also makes clear, even at its gloomiest, is the key place of drama in the Victorian imagination. After Irving's death in 1905, the Russell-Cotes bought many of Irving's personal effects at auction. Adding these to their existing collection of Irving memorabilia and other theatrical paintings and souvenirs, they converted the bedroom in which Irving had stayed into a permanent shrine to his memory. The Henry Irving Room would make an ideal introduction to most of the contents of this volume.

    The steam-assisted gravity drainage (SAGD) technique is among the most effective steam injection methods and is widely applied in Canadian oil-sand reservoirs. The SAGD technology uses hot steam to decrease bitumen viscosity and allow it to flow. Japan Canada Oil Sands Limited (JACOS) has been developing an oil-sand reservoir in the Alberta's Hangingstone area since 1997. This paper focused on the western area of the reservoir and reported on a study that estimated the steam-chamber extent generated by horizontal well pairs. It listed steam injection start time for each well of the western area. Steam-chamber distribution was determined by distinguishing high temperature and high pore-pressure zones from low temperature and high pore-pressure zones. The bitumen recovery volume in the steam-chamber zone was estimated and compared with the actual cumulative production. This paper provided details of the methodology and interpretation procedures for the quantitative method to interpret 4D-seismic data for a SAGD process. A procedure to apply a petrophysical model was demonstrated first by scaling laboratory measurements to field-scale applications, and then by decoupling pressure and temperature effects. The first 3D seismic data in this study were already affected by higher pressures and temperatures. 11 refs., 3 tabs., 12 figs.

    2014-03-01

    Modern, self-contained introduction to the subject matter. Emphasizes the interplay between theory and experiment. Course-tested tutorial style, contains many derivations. Nuclei and nuclear reactions offer a unique setting for investigating three (and in some cases even all four) of the fundamental forces in nature. Nuclei have been shown - mainly by performing scattering experiments with electrons, muons, and neutrinos - to be extended objects with complex internal structures: constituent quarks; gluons, whose exchange binds the quarks together; sea-quarks, the ubiquitous virtual quark-antiquark pairs and, last but not least, clouds of virtual mesons, surrounding an inner nuclear region, their exchange being the source of the nucleon-nucleon interaction. The interplay between the (mostly attractive) hadronic nucleon-nucleon interaction and the repulsive Coulomb force is responsible for the existence of nuclei; their degree of stability, expressed in the details and limits of the chart of nuclides; their rich structure and the variety of their interactions. Despite the impressive successes of the classical nuclear models and of ab-initio approaches, there is clearly no end in sight for either theoretical or experimental developments as shown e.g. by the recent need to introduce more sophisticated three-body interactions to account for an improved picture of nuclear structure and reactions. Yet, it turns out that the internal structure of the nucleons has comparatively little influence on the behavior of the nucleons in nuclei, and nuclear physics - especially nuclear structure and reactions - is thus a field of science in its own right, without much recourse to subnuclear degrees of freedom. This book collects essential material that was presented in the form of lectures notes in nuclear physics courses for graduate students at the University of Cologne.

    Production of bio-based products that are cost competitive in the market place requires well-developed operations that include innovative processes and separation solutions. Separations costs can make the difference between an interesting laboratory project and a successful commercial process. Bioprocessing and separations research and development addresses some of the most significant cost barriers in production of bioffuels and bio-based chemicals. Models of integrated biorefineries indicate that success will require production of higher volume fuels in conjunction with high margin chemical products. Addressing the bioprocessing and separations cost barriers will be critical to the overall success of the integrated biorefinery.

  2. A Practical Introduction to Skeletons for the Plant Sciences

    Directory of Open Access Journals (Sweden)

    Alexander Bucksch

    2014-08-01

    Full Text Available Before the availability of digital photography resulting from the invention of charged couple devices in 1969, the measurement of plant architecture was a manual process either on the plant itself or on traditional photographs. The introduction of cheap digital imaging devices for the consumer market enabled the wide use of digital images to capture the shape of plant networks such as roots, tree crowns, or leaf venation. Plant networks contain geometric traits that can establish links to genetic or physiological characteristics, support plant breeding efforts, drive evolutionary studies, or serve as input to plant growth simulations. Typically, traits are encoded in shape descriptors that are computed from imaging data. Skeletons are one class of shape descriptors that are used to describe the hierarchies and extent of branching and looping plant networks. While the mathematical understanding of skeletons is well developed, their application within the plant sciences remains challenging because the quality of the measurement depends partly on the interpretation of the skeleton. This article is meant to bridge the skeletonization literature in the plant sciences and related technical fields by discussing best practices for deriving diameters and approximating branching hierarchies in a plant network.

  3. New Product Introduction in the Pharmaceutical Industry

    DEFF Research Database (Denmark)

    Hansen, Klaus Reinholdt Nyhuus

    Due to the limited time of the monopoly provided by patent protection that is used for recouping the R&D investment, pharmaceutical companies focus on keeping time-to-market for new products as short as possible. This process is however getting more uncertain, as the outcome of clinical trials...... is unknown and negotiations with authorities have become harder, making market introduction more difficult. This dissertation treats the new product introduction process in the pharmaceutical industry from an operations perspective. The overarching aim of this dissertation is to improve the planning...... uncertainty and several important industry characteristics. The model is used to gain several insights on the use of risk packaging and on keeping time-to-market short. As capacity in secondary pharmaceutical production is critical for product availability, a capacity planning model for a new drug delivery...

  8. An introduction to random interlacements

    CERN Document Server

    Drewitz, Alexander; Sapozhnikov, Artëm

    2014-01-01

    This book gives a self-contained introduction to the theory of random interlacements. The intended reader of the book is a graduate student with a background in probability theory who wants to learn about the fundamental results and methods of this rapidly emerging field of research. The model was introduced by Sznitman in 2007 in order to describe the local picture left by the trace of a random walk on a large discrete torus when it runs up to times proportional to the volume of the torus. Random interlacements is a new percolation model on the d-dimensional lattice. The main results covered by the book include the full proof of the local convergence of random walk trace on the torus to random interlacements and the full proof of the percolation phase transition of the vacant set of random interlacements in all dimensions. The reader will become familiar with the techniques relevant to working with the underlying Poisson Process and the method of multi-scale renormalization, which helps in overcoming the ch...

  9. Introduction to market power issues

    International Nuclear Information System (INIS)

    2002-01-01

    This paper presents an initial introduction to market power issues in wholesale electric power markets. Market power was described as the ability of sellers to act together to profitably maintain prices above competitive levels for a significant period of time. The two general forms of market power, vertical and horizontal market power, were described with reference to how they may be exercised. The factors that should be considered when evaluating the competitiveness of a market include: (1) market share of suppliers, (2) overall market concentration, (3) elasticity of demand, (4) shape of the industry supply curve, (5) the amount and distribution of excess supply, (6) typical contractual arrangements and the process for establishing prices, and (7) the relative ease to enter the market. It was noted that a narrow market scope allows only wholesale market sector (such as municipal utilities) to access competitive electricity supplies, however, a more expansive definition of market scope would consider the sale of electricity to industrial customers. This would allow more players to enter the Nova Scotia market. The barriers to entry for wholesale electric power markets are: (1) access to the transmission grids and services, (2) sites for new capacity development, (3) major inputs to power generation, (4) transportation of major inputs to generation, and (5) lack of liquidity

  10. Introduction: Towards Sustainable 2020 Nanoelectronics

    Science.gov (United States)

    Hoefflinger, Bernd

    Faced with the immanent end of the nanometer roadmap at 10 nm, and with an electronics energy crisis, we have to engineer the largest strategy change in the 50-years history of microelectronics, renamed to nanoelectronics in 2000 with the first chips containing 100-nm transistors. Accepting the 10 nm-limit, the new strategy for the future growth of chip functionalities and markets has to deliver, within a decade, another 1,000× improvement in the energy per processing operation as well as in the energy per bit of memory and of communication. As a team from industry and from research, we present expectations, requirements and possible solutions for this challenging energy scenario of femto- and atto-Joule electronics. The introduction outlines the book's structure, which aims to describe the innovation eco-system needed for optimum-energy, sustainable nanoelectronics. For the benefit of the reader, chapters are grouped together into interest areas like transistors and circuits, technology, products and markets, radical innovations, as well as business and policy issues.

    Integration of conservation partnerships across geographic, biological, and administrative boundaries is increasingly relevant because drivers of change, such as climate shifts, transcend these boundaries. We explored successes and challenges of established conservation programs that span multiple watersheds and consider both social and ecological concerns. We asked representatives from a diverse set of 11 broad-extent conservation partnerships in 29 countries 17 questions that pertained to launching and maintaining partnerships for broad-extent conservation, specifying ultimate management objectives, and implementation and learning. Partnerships invested more funds in implementing conservation actions than any other aspect of conservation, and a program's context (geographic extent, United States vs. other countries, developed vs. developing nation) appeared to substantially affect program approach. Despite early successes of these organizations and benefits of broad-extent conservation, specific challenges related to uncertainties in scaling up information and to coordination in the face of diverse partner governance structures, conflicting objectives, and vast uncertainties regarding future system dynamics hindered long-term success, as demonstrated by the focal organizations. Engaging stakeholders, developing conservation measures, and implementing adaptive management were dominant challenges. To inform future research on broad-extent conservation, we considered several challenges when we developed detailed questions, such as what qualities of broad-extent partnerships ensure they complement, integrate, and strengthen, rather than replace, local conservation efforts and which adaptive management processes yield actionable conservation strategies that account explicitly for dynamics and uncertainties regarding multiscale governance, environmental conditions, and knowledge of the system? © 2014 Society for Conservation Biology.

  17. Biophysics An Introduction

    CERN Document Server

    Glaser, Roland

    2012-01-01

    Biophysics is the science of physical principles underlying all processes of life, including the dynamics and kinetics of biological systems. This fully revised 2nd English edition is an introductory text that spans all steps of biological organization, from the molecular, to the organism level, as well as influences of environmental factors. In response to the enormous progress recently made, especially in theoretical and molecular biophysics, the author has updated the text, integrating new results and developments concerning protein folding and dynamics, molecular aspects of membrane assembly and transport, noise-enhanced processes, and photo-biophysics. The advances made in theoretical biology in the last decade call for a fully new conception of the corresponding sections. Thus, the book provides the background needed for fundamental training in biophysics and, in addition, offers a great deal of advanced biophysical knowledge.

  18. [Introduction to grounded theory].

    Wang, Shou-Yu; Windsor, Carol; Yates, Patsy

    2012-02-01

    Grounded theory, first developed by Glaser and Strauss in the 1960s, was introduced into nursing education as a distinct research methodology in the 1970s. The theory is grounded in a critique of the dominant contemporary approach to social inquiry, which imposed "enduring" theoretical propositions onto study data. Rather than starting from a set theoretical framework, grounded theory relies on researchers distinguishing meaningful constructs from generated data and then identifying an appropriate theory. Grounded theory is thus particularly useful in investigating complex issues and behaviours not previously addressed and concepts and relationships in particular populations or places that are still undeveloped or weakly connected. Grounded theory data analysis processes include open, axial and selective coding levels. The purpose of this article was to explore the grounded theory research process and provide an initial understanding of this methodology.

  19. Probability an introduction

    CERN Document Server

    Grimmett, Geoffrey

    2014-01-01

    Probability is an area of mathematics of tremendous contemporary importance across all aspects of human endeavour. This book is a compact account of the basic features of probability and random processes at the level of first and second year mathematics undergraduates and Masters' students in cognate fields. It is suitable for a first course in probability, plus a follow-up course in random processes including Markov chains. A special feature is the authors' attention to rigorous mathematics: not everything is rigorous, but the need for rigour is explained at difficult junctures. The text is enriched by simple exercises, together with problems (with very brief hints) many of which are taken from final examinations at Cambridge and Oxford. The first eight chapters form a course in basic probability, being an account of events, random variables, and distributions - discrete and continuous random variables are treated separately - together with simple versions of the law of large numbers and the central limit th...

    2015-01-01

    Western blotting is an important procedure for the immunodetection of proteins, particularly proteins that are of low abundance. This process involves the transfer of protein patterns from gel to microporous membrane. Electrophoretic as well as non-electrophoretic transfer of proteins to membranes was first described in 1979. Protein blotting has evolved greatly since the inception of this protocol, allowing protein transfer to be accomplished in a variety of ways.
