Sample records for modern kinetic thoery

  1. Q-branch Raman scattering and modern kinetic thoery

    Energy Technology Data Exchange (ETDEWEB)

    Monchick, L. [The Johns Hopkins Univ., Laurel, MD (United States)

    1993-12-01

    The program is an extension of previous APL work whose general aim was to calculate line shapes of nearly resonant isolated line transitions with solutions of a popular quantum kinetic equation-the Waldmann-Snider equation-using well known advanced solution techniques developed for the classical Boltzmann equation. The advanced techniques explored have been a BGK type approximation, which is termed the Generalized Hess Method (GHM), and conversion of the collision operator to a block diagonal matrix of symmetric collision kernels which then can be approximated by discrete ordinate methods. The latter method, which is termed the Collision Kernel method (CC), is capable of the highest accuracy and has been used quite successfully for Q-branch Raman scattering. The GHM method, not quite as accurate, is applicable over a wider range of pressures and has proven quite useful.

  2. Modern quantum kinetic theory and spectral line shapes

    Monchick, L.

    1991-01-01

    The modern quantum kinetic theory of spectral line shapes is outlined and a typical calculation of a Raman scattered line shape described. The distinguishing feature of this calculation is that it was completely ab initio and therefore constituted a test of modern quantum kinetic theory, the state of the art in computing molecular-scattering cross sections, and novel methods of solving kinetic equations. The computation employed a large assortment of tools: group theory, finite-element methods, classic methods of solving coupled sets of ordinary differential equations, graph methods of combining angular momenta, and matrix methods of solving integral equations. Agreement with experimental results was excellent. 13 refs

  3. Modern aspects of the kinetic theory of glass transition

    International Nuclear Information System (INIS)

    Tropin, T V; Aksenov, V L; Schmelzer, J W

    2016-01-01

    This paper reviews glass transition kinetics models that are developed to describe the formation of structural (for example, covalent and metallic) glasses, as well as to account for the transition of a polymer to a solid glassy state. As the two approaches most frequently used over the last decade to model the glass transition, the Tool–Narayanaswamy–Moynihan model and the Adam–Gibbs theory of glass transition are described together with examples of their applications. Also discussed are entropy-based approaches that rely on irreversible thermodynamics methods originated in the work of De Donder, Mandelstam, and Leontovich. The actual problems that arise in applying these methods and the prospects of their development are discussed. A brief overview of statistical glass transition models is given, including the mode-coupling and energy-landscape theories. (reviews of topical problems)

    The importance of (n,xn) reactions must be taken into consideration while calculating the kinetic parameters of subcritical assemblies driven by an external neutron source. This study is divided into two parts, the first part is dedicated to the classic definition of the neutron source multiplication factor and two alternative calculation methodologies are compared. The second part considers a new definition of the kinetic parameters for subcritical assemblies, with particular emphasis on the delayed neutron fraction and generation time. This new definition has been modified to take into account the external neutron source and (n,xn) reactions, which increase the fraction of prompt neutrons. The developed theoretical framework has been applied by Monte Carlo and deterministic calculations to the YALINA Thermal subcritical assembly in Belarus. This facility can be driven by californium, deuterium-deuterium (D-D), or deuterium-tritium (D-T) external neutron sources. For the D-T neutron source, (n,xn) reactions must be taken into account in order to produce accurate results because the average energy of D-T source neutrons is 14.1 MeV, a value much higher than the threshold energy of the (n,2n) cross section of uranium isotopes.

    Ductile fracture mechanisms during uniaxial tensile testing of two different modern high strength dual phase steels, i.e. DP780 and DP980, were studied. Detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy as well as EBSD examination. The results revealed that interface decohesion, especially at martensite particles located at ferrite grain boundaries, was the most probable mechanism for void nucleation. It was also revealed that the creation of cellular substructure can reduce stored strain energy and thereby, higher true fracture strain was obtained in DP980 than DP780 steel. Prediction of void growth behavior based on some previously proposed models showed unreliable results. Therefore, a modified model based on Rice-Tracey family models was proposed which showed a very lower prediction error compared with other models. - Highlights: • Damage mechanism in two modern high strength dual phase steels was studied. • Creation of cellular substructures can reduce the stored strain energy within the ferrite grains. • The experimental values were examined by Agrawal as well as RT family models. • A modified model was proposed for prediction of void growth behavior of DP steels.

    Full Text Available A strategy for the second modernization raises, beyond objectives, a series of epistemicresponsibilities. It is known that modernization stemming from the Enlightment had, among other things,the pretense that it is a project which is self-legitimating. Its profound rationales are the only justification.Referential self-centering proved to be the one that made possible a practice of the new. Modernizationhaving the function of renouncing myth – meaning an eliminatory formula for the past – and thefixation in the opportunity and potentiality of the present, seemed to close an insoluble but extremelyengrossing problem: that of a propensity towards utopia, of the risky escape towards the future. Thetraditionalization of the new constitutes a support for the daring to break out of the captivity of themoment.Modernization becomes the experience of combining the new which, thus, creates a succession ofpresent times. The future is no longer the result of fantasy, but a system’s direct expression to combine thenew. Therefore the future is an option for one or another model of the present, often tested previouslysomewhere else. In a non-metaphysical way, the future can be seen, touched, tried, lived by simplegeographical movement. The sense of evolution has de-temporalized taking the form of the concomitant,parallel, enclosed, neighboring space. We just have to be in the trend, to evolve in the context.Globalization defines the context and its conception – as a project of the second modernity – showsus the trends. The problem is how to understand the context in order to find the sense of the trend. Are wethe load the sense with the values of the first modernity or will we have to turn to the values of anothermodernity? Why do we have to move away from the significance of the processes which made up the firstmodernity? How do we relate to the content of the new context in which the structural trends of today’sworld are taking place? What is the

    2014-12-01

    Full Text Available “Modernity” has recently been the subject of considerable discussion among historians. This article reviews some of the debates and argues that modernity is a problematic concept because it implies a complete rupture with “traditional” ways of life. Studies of key terms are undertaken with the aid of Google Ngrams. These show that “modernity,” “modern times,” and “traditional” —in English and other languages— have a history of their own. A brief analysis of the shift from a self oriented toward equilibrium to a self oriented toward stimulation demonstrates that modernity is not necessary to historical analysis.

    In this paper, a quantum model for the binomial market in finance is proposed. We show that its risk-neutral world exhibits an intriguing structure as a disk in the unit ball of ${\\bf R}^3,$ whose radius is a function of the risk-free interest rate with two thresholds which prevent arbitrage opportunities from this quantum market. Furthermore, from the quantum mechanical point of view we re-deduce the Cox-Ross-Rubinstein binomial option pricing formula by considering Maxwell-Boltzmann statist...

    This textbook introduces thermodynamics with a modern approach, starting from four fundamental physical facts (the atomic nature of matter, the indistinguishability of atoms and molecules of the same species, the uncertainty principle, and the existence of equilibrium states) and analyzing the behavior of complex systems with the tools of information theory, in particular with Shannon's measure of information (or SMI), which can be defined on any probability distribution. SMI is defined and its properties and time evolution are illustrated, and it is shown that the entropy is a particular type of SMI, i.e. the SMI related to the phase-space distribution for a macroscopic system at equilibrium. The connection to SMI allows the reader to understand what entropy is and why isolated systems follow the Second Law of Thermodynamics. The Second Llaw is also formulated for other systems, not thermally isolated and even open with respect to the transfer of particles. All the fundamental aspects of thermodynamics are d...

Basic knowledge about the physico-chemical properties of heparin and its interactions with proteins resulting in anticoagulant and lipolytic effects are discussed in a review (chapter II), which also comprises some clinical aspects of heparin therapy. In chapter III the kinetics of the anticoagulant effect are described after intravenous administration of five commercial heparin preparations. A mathematical model is presented that fits best to these kinetics. The kinetics of the anticoagulant and lipolytic effects after intravenous injection of various 35 S-radiolabelled heparin fractions and their relationship with the disappearance of the radiolabel are described in chapter IV. Chapter V gives a description of the kinetics of two radiolabels after injection of in vitro formed complexes consisting of purified, 125 I-radiolabelled antithrombin III and various 35 S-radiolabelled heparin fractions.

  11. Modern Supersymmetry

    International Nuclear Information System (INIS)

    Kulish, Petr P

    2006-01-01

    We have spent more than twenty years applying supersymmetry (SUSY) to elementary particle physics and attempting to find an experimental manifestation of this symmetry. Terning's monograph demonstrates the strong influence of SUSY on theoretical elaborations in the field of elementary particles. It gives both an overview of modern supersymmetry in elementary particle physics and calculation techniques. The author, trying to be closer to applications of SUSY in the real world of elementary particles, is also anticipating the importance of supersymmetry for rigorous study of nonperturbative phenomena in quantum field theory. In particular, he presents the 'exact' SUSY β function using instanton methods, phenomena of anomalies and dualities. Supersymmetry algebra is introduced by adding two anticommuting spinor generators to Poincare algebra and by presenting massive and massless supermultiplets of its representations. The author prefers to use mostly the component description of field contents of the theories in question rather than the superfield formalism. Such a style makes the account closer to physical characteristics. Relations required by SUSY among β functions of the gauge, Yukawa and quartic interactions are checked by direct calculations as well as to all orders in perturbation theory, thus demonstrating that SUSY survives quantization. A discussion is included of the hierarchy problem of different scales of weak and strong interactions and its possible solution by the minimal supersymmetric standard model. Different SUSY breaking mechanisms are presented corresponding to a realistic phenomenology. The monograph can also be considered as a guide to 'duality' relations connecting different SUSY gauge theories, supergravities and superstrings. This is demonstrated referring to the particular properties and characteristics of these theories (field contents, scaling dimensions of appropriate operators etc). In particular, the last chapter deals with the Ad

    By using density gradient materials enriched with autologous plasma, the authors have been able to isolate granulocutes from other cellular elements and label them with In-111 without separation from a plasma environment. The kinetic behavior of these cells suggests that phenomena attributed to granulocyte activation are greatly reduced by this labeling. Here, they review their study of granulocyte kinetics in health and disease in hope of quantifying sites of margination and identifying principal sites of destruction. The three principle headings of the paper are distribution, life-span, and destruction

    2018-02-01

    The stable Cr isotope fractionation preserved in natural substances has been attributed predominantly to Cr(III)-Cr(VI) redox transformations. However, non-redox reaction pathways (e.g., ligand-promoted dissolution, ligand exchange, adsorption of Cr(III)) are liable to contribute to isotopic fractionation in natural systems given that soluble Cr(III)-ligands have been directly documented or modeled in several marine, continental, and hydrothermal environments. This study isolates the stable Cr isotope fractionation accompanying Cl-H2O ligand exchange during the transformation of three aqueous species in the Cr(III)-Cl-H2O system, [CrCl2(H2O)4]+aq (abr. CrCl2+ or S1), [CrCl(H2O)5]2+aq (abr. CrCl2+ or S2), and [Cr(H2O)6]3+aq (abr. Cr3+ or S3), at low pH (≤2). In dilute HCl (0.01 to 1 M), Cr3+ is the kinetically favoured species and transformation of CrCl2+ to CrCl2+ to Cr3+ via 2 steps of dechlorination/hydrolyzation begins immediately upon dissolution of a Cr(III)-Cl solid. Individual species are separated with cation exchange chromatography at different stages of transformation and inter- and intra-species (across an elution peak of one species) isotopic fractionation of up to 1 and 2‰ (δ53/52Cr), respectively, is documented. Comparison of peak elution characteristics with Cr-Cl-H-O isotopologue mass abundances suggests mass-dependent sorting of isotopologues alone cannot explain intra-species fractionation, supporting a previously published proposal that preferential adsorption of light Cr isotopes on the resin is driven by vibrational energy effects. The transformation of CrCl2+ to CrCl2+ is faster than CrCl2+ to Cr3+ and the rates of both transformations increase with solution pH. Preferential reaction of light Cr(III) isotopes into product species occurs during each transformation, consistent with closed-system, kinetic fractionation during Cl-H2O ligand exchange. Inter-species fractionation is assessed using time-series experiments beginning from the

  17. Kinetic theory and transport phenomena

    CERN Document Server

    Soto, Rodrigo

    2016-01-01

    This textbook presents kinetic theory, which is a systematic approach to describing nonequilibrium systems. The text is balanced between the fundamental concepts of kinetic theory (irreversibility, transport processes, separation of time scales, conservations, coarse graining, distribution functions, etc.) and the results and predictions of the theory, where the relevant properties of different systems are computed. The book is organised in thematic chapters where different paradigmatic systems are studied. The specific features of these systems are described, building and analysing the appropriate kinetic equations. Specifically, the book considers the classical transport of charges, the dynamics of classical gases, Brownian motion, plasmas, and self-gravitating systems, quantum gases, the electronic transport in solids and, finally, semiconductors. Besides these systems that are studied in detail, concepts are applied to some modern examples including the quark–gluon plasma, the motion of bacterial suspen...

  18. Physisorption kinetics

    CERN Document Server

    Kreuzer, Hans Jürgen

    1986-01-01

    This monograph deals with the kinetics of adsorption and desorption of molecules physisorbed on solid surfaces. Although frequent and detailed reference is made to experiment, it is mainly concerned with the theory of the subject. In this, we have attempted to present a unified picture based on the master equation approach. Physisorption kinetics is by no means a closed and mature subject; rather, in writing this monograph we intended to survey a field very much in flux, to assess its achievements so far, and to give a reasonable basis from which further developments can take off. For this reason we have included many papers in the bibliography that are not referred to in the text but are of relevance to physisorption. To keep this monograph to a reasonable size, and also to allow for some unity in the presentation of the material, we had to omit a number of topics related to physisorption kinetics. We have not covered to any extent the equilibrium properties of physisorbed layers such as structures, phase tr...

  19. A century of enzyme kinetic analysis, 1913 to 2013.

    Science.gov (United States)

    Johnson, Kenneth A

    2013-09-02

    This review traces the history and logical progression of methods for quantitative analysis of enzyme kinetics from the 1913 Michaelis and Menten paper to the application of modern computational methods today. Following a brief review of methods for fitting steady state kinetic data, modern methods are highlighted for fitting full progress curve kinetics based upon numerical integration of rate equations, including a re-analysis of the original Michaelis-Menten full time course kinetic data. Finally, several illustrations of modern transient state kinetic methods of analysis are shown which enable the elucidation of reactions occurring at the active sites of enzymes in order to relate structure and function.

  20. Stochastic kinetics

    International Nuclear Information System (INIS)

    Colombino, A.; Mosiello, R.; Norelli, F.; Jorio, V.M.; Pacilio, N.

    1975-01-01

    A nuclear system kinetics is formulated according to a stochastic approach. The detailed probability balance equations are written for the probability of finding the mixed population of neutrons and detected neutrons, i.e. detectrons, at a given level for a given instant of time. Equations are integrated in search of a probability profile: a series of cases is analyzed through a progressive criterium. It tends to take into account an increasing number of physical processes within the chosen model. The most important contribution is that solutions interpret analytically experimental conditions of equilibrium (moise analysis) and non equilibrium (pulsed neutron measurements, source drop technique, start up procedures)

    International Nuclear Information System (INIS)

    Hicks, D.R.; Kraml, M.; Cayen, M.N.; Dubuc, J.; Ryder, S.; Dvornik, D.

    1984-01-01

    The kinetics of tolrestat, a potent inhibitor of aldose reductase, were examined. Serum concentrations of tolrestat and of total 14 C were measured after dosing normal subjects and subjects with diabetes with 14 C-labeled tolrestat. In normal subjects, tolrestat was rapidly absorbed and disappearance from serum was biphasic. Distribution and elimination t 1/2s were approximately 2 and 10 to 12 hr, respectively, after single and multiple doses. Unchanged tolrestat accounted for the major portion of 14 C in serum. Radioactivity was rapidly and completely excreted in urine and feces in an approximate ratio of 2:1. Findings were much the same in subjects with diabetes. In normal subjects, the kinetics of oral tolrestat were independent of dose in the 10 to 800 mg range. Repetitive dosing did not result in unexpected cumulation. Tolrestat was more than 99% bound to serum protein; it did not compete with warfarin for binding sites but was displaced to some extent by high concentrations of tolbutamide or salicylate

    Through analysis of key texts, I seek to demonstrate the explanative potential of Durkheim’s sociology of religion in the present context. I critically readdress the idea, found in his early work, that modernity is characterized by a rupture with pre-modern forms of solidarity. First, I investigate...... the ways in which Durkheim sets up a stark distinction between the pre-modern and the modern in his early work, and how this distinction is further cemented by his orthodox critique of the modern economy and its negative effects on social life. Second, I show how another timeless and positive understanding...... of “mechanical” solidarity is to be found behind the “symbolist” template crystalizing in Durkheim’s late work. Third, I develop this template for a modern context by critically addressing and removing other obstacles and prejudices on Durkheim’s part....

    Energy Technology Data Exchange (ETDEWEB)

    Kristensen, Hans M. [Federation of American Scientists, Washington, DC (United States)

    2014-05-09

    This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

    2014-12-01

    Full Text Available Performing an art, either by painting or by sculpturing, requires to be interdisciplinary. When an artist creates his/her work of art, the process he/she realizes is supported by different engineering disciplines. Therefore, especially modern artists need to understand engineering science and this results in transforming artists into engineers. Opportunities provided by technology and science enable artists to expand his/her vision and to improve his/her works. Especially kinetic art has become an approach that combines art with engineering. Kinetic art, which is nourished with varied disciplines, is an excellent example to prove that art is interdisciplinary and to show the relationship between artist/art and engineering.

    “modernities” over the last 10 years, this paper wishes to address the analytical usefulness of this conceptual development. What is it about these concepts that make them useful as we try to capture the World today? Rather than providing any substantial definitions as to what those modernities are about (or...... what they are not about), anthropologists have used ethnographies to demonstrate how modernities are lived and constructed differently in different cultural contexts. To a very large extent, anthropologists intend these multiple modernities to refer to the interplay between local and global...... configurations. However, if the current pluralizing of modernity ultimately serves to describe the variety of cultural forms that co-exist in the World today, the analytical value of the concept risks being watered down, and little is gained in perspective. Arguably, other concepts would have served the purpose...

  2. Modern optimization with R

    CERN Document Server

    Cortez, Paulo

    2014-01-01

    The goal of this book is to gather in a single document the most relevant concepts related to modern optimization methods, showing how such concepts and methods can be addressed using the open source, multi-platform R tool. Modern optimization methods, also known as metaheuristics, are particularly useful for solving complex problems for which no specialized optimization algorithm has been developed. These methods often yield high quality solutions with a more reasonable use of computational resources (e.g. memory and processing effort). Examples of popular modern methods discussed in this book are: simulated annealing; tabu search; genetic algorithms; differential evolution; and particle swarm optimization. This book is suitable for undergraduate and graduate students in Computer Science, Information Technology, and related areas, as well as data analysts interested in exploring modern optimization methods using R.

    2015-03-01

    Full Text Available Nowadays it is essential to modernize credit relations in the conditions of global economy transformations. This is due to the influence of integration processes on credit relations and transformation of the risks inherent in the credit field. The purpose of this article is to develop measures that help to improve the efficiency of interaction of credit relations’ participants. Modernization of credit relations is based on the interaction of its main and indirect subjects who belong to the subsystems of loans granting, deposits attraction and provision of related services. Its goal is to pass from extensive to intensive model of interaction between the subjects of credit relations. Components of the credit relations modernization are the following: institutional modernization, which is based on the interaction of credit relations’ subjects, and ensures the development of competition in all credit market’s segments, the creation of its corresponding infrastructure, qualitative change in the approaches of regulation and supervision; technological modernization, which involves the formation of joint products on the credit market and the formation of an integrated informational and analytical system. In the result of the credit relations’ modernization it is expected to achieve synergies between the subjects of credit relations, that will lead to changes in the business architecture of the financial market.

    2017-01-01

    Statistical mechanics has been proven to be successful at describing physical systems at thermodynamic equilibrium. Since most natural phenomena occur in nonequilibrium conditions, the present challenge is to find suitable physical approaches for such conditions: this book provides a pedagogical pathway that explores various perspectives. The use of clear language, and explanatory figures and diagrams to describe models, simulations and experimental findings makes the book a valuable resource for undergraduate and graduate students, and also for lecturers organizing teaching at varying levels of experience in the field. Written in three parts, it covers basic and traditional concepts of nonequilibrium physics, modern aspects concerning nonequilibrium phase transitions, and application-orientated topics from a modern perspective. A broad range of topics is covered, including Langevin equations, Levy processes, directed percolation, kinetic roughening and pattern formation.

  15. KINETIC ALGORITHMS FOR HARBOUR MANAGEMENT

    Directory of Open Access Journals (Sweden)

    C. M. Gold

    2012-07-01

    Full Text Available Modern harbour management for a busy port needs to resolve a variety of simultaneous problems. Harbour traffic may be busy and the waterways congested, both by the major shipping and by the attendant harbour tugs. The harbour channel may be narrow and tortuous, and rapidly changing tides may require frequent course adjustments. Navigation aids must be clearly specified and immediately identifiable, in order to permit safe passage for the vessels. This requires a GIS with attributes not easily available with traditional products. The GeoVS system is a kinetic GIS with full three-dimensional visualisation, so that ships, bathymetry and landscape may be viewed in a form that is immediately understandable to both harbour pilots and the harbour authority. The system is kinetic because the data structures used to preserve the topological relationships between ships, seafloor and coastline are able to be maintained on a real-time basis, taking account of ship movement recorded on the compulsory AIS (Automatic Information System beacons. Maintenance of this real-time topology allows for easy detection of potential collisions, as well as real-time bathymetric estimations, necessary to prevent ship grounding in highly tidal environments. The system, based on previous research into kinetic Voronoi diagrams, as well as development of a completely new graphical engine, is now in commercial production, where its advantages over simpler twodimensional models without automatic collision and grounding detection are becoming evident. Other applications are readily envisaged, and will be addressed in the near future.

    Instrumentation and control contributed a major share to the current level of safety, economic efficiency, and availability of the German nuclear power plants. German NPPs occupy a top position in this respect at international level, but novel instrumentation and digital control technology alone will not guarantee further enhancements. Therefore, the owner/operators established carefully devised maintenance and modernization strategies in order to safeguard their NPPs top position in the long run. The German NPPs are the most thoroughly automated plants of the world. In addition to the sweeping modernization strategies recommended by the plant manufacturers, based on computer-supported control, alternative modernization strategies have been considered in the evaluation process. This approach provides for room for maneuvre, for manufacturers as well as managers responsible for risk and cost optimization, which is a major task in view of the changing regulatory framework in the electricity market.

  20. Modernization mixed with nationalism

    Directory of Open Access Journals (Sweden)

    Nikiforov Konstantin V.

    2014-01-01

    Full Text Available This essay reflects on a particular manner in which modernisation have taken place in the Balkans in modern history, from the 1878 Berlin Congress onwards. The Balkan countries faced twofold difficulties in their development: they had to overcome their backwardness stemming from the centuries of the Ottoman yoke and catch up with modern Western Europe, and resolve their numerous mutual territorial and political disputes. The latter task was especially difficult due to the constant interference in Balkan affairs on the part of Great Powers. This interference further aggravated nationalistic tensions between the Balkan states. The peculiar mixture of modernisation efforts and nationalism remains to this day when the entire region strives to join the European Union.

    1996-11-01

    Knud E. Hansen A/S (KEH) has, partly funded by the Energy Research Programme, (EFP-95) investigated in the possibilities of using windships for transportation of cargo on long routes, i.e. across the Atlantic or Pacific Ocean. The task was to peruse experiences from projects made during the past 30 years and then, based on new materials and design principle to make proposals to modern wind driven ships to transportation of cargo - especially bulk carriers. KEH has thus prepared a suggestion for a 50,000 DWT wind driven bulk carrier on these terms. The bulk carrier in question is a modern rig inspired by the classical lugger and junk sail with a total sail area of abt. 10,000 m{sup 2}. The hull of the ship has been developed in order to limit wave resistance and drifting. Project Windship has, in contrast to earlier tests and projects, designed a bulk carrier based on a complete evaluation of ecology, safety, economy and reasonable transportation speed. The research project shows that international sea transportation, with wind as the primary source of energy, does not seem to run up against any obstacles as regards safety. The economical analyses show that windship transportation, with today`s oil prices, will be about 10% higher compared to the diesel driven transportation. In the light of the positive results of the research project the steering committee recommends that phase II of project `Modern Windships` is carried out. (EG)

  16. Code Modernization of VPIC

    Science.gov (United States)

    Bird, Robert; Nystrom, David; Albright, Brian

    2017-10-01

    The ability of scientific simulations to effectively deliver performant computation is increasingly being challenged by successive generations of high-performance computing architectures. Code development to support efficient computation on these modern architectures is both expensive, and highly complex; if it is approached without due care, it may also not be directly transferable between subsequent hardware generations. Previous works have discussed techniques to support the process of adapting a legacy code for modern hardware generations, but despite the breakthroughs in the areas of mini-app development, portable-performance, and cache oblivious algorithms the problem still remains largely unsolved. In this work we demonstrate how a focus on platform agnostic modern code-development can be applied to Particle-in-Cell (PIC) simulations to facilitate effective scientific delivery. This work builds directly on our previous work optimizing VPIC, in which we replaced intrinsic based vectorisation with compile generated auto-vectorization to improve the performance and portability of VPIC. In this work we present the use of a specialized SIMD queue for processing some particle operations, and also preview a GPU capable OpenMP variant of VPIC. Finally we include a lessons learnt.

  18. Recent characterizations of generalized convexity in convexity in cooperative game thoery

    Energy Technology Data Exchange (ETDEWEB)

    Driessen, T.

    1994-12-31

    The notion of convexity for a real-valued function on the power set of the finite set N (the so-called cooperative game with player set N) is defined as in other mathematical fields. The study of convexity plays an important role within the field of cooperative game theory because the application of the solution part of game theory to convex games provides elegant results for the solution concepts involved. Especially, the well known solution concept called core is, for convex games, very well characterized. The current paper focuses on a notion of generalized convexity, called k- convexity, for cooperative n-person games. Due to very recent characterizations of convexity for cooperative games, the goal is to provide similar new characterizations of k-convexity. The main characterization states that for the k-convexity of an n-person game it is both necessary and sufficient that half of all the so-called marginal worth vectors belong to the core of the game. Here it is taken into account whether a marginal worth vector corresponds to an even or odd ordering of k elements of the n-person player set N. Another characterization of k-convexity is presented in terms of a so-called finite min-modular decomposition. That is, some specific cover game of a k-convex game can be decomposed as the minimum of a finite number of modular (or additive) games. Finally it is established that the k-convexity of a game can be characterized in terms of the second order partial derivates of the so-called multilinear extension of the game.

  19. Institutions and Modernity

    Directory of Open Access Journals (Sweden)

    Witold Morawski

    2013-09-01

    Full Text Available Purpose: Modernity consists of many confl icting aspects: It brings many empty promises, yet has resulted in new institutions that create bridges between the values and interests of millions of people who seek freedom, prosperity, quality of life, strengthened democracy and social justice. In this paper I attempt to a gain and loss account against modernity, because institutional rules are not only conducive to cooperative interactions, but to hostile interactions as well. People are not always guided by moral commitment, but rather more often driven by cold calculation or coercion.Methodology: Modernity has at least three defi nitions. The fi rst defi nition is based on ideas that took over the imagination of the era. The second defi nition is based on an analysis of the behavior of people who respond to reason as well as emotion and believe that they act more rationally than their ancestors or the traditional “others”. The third defi nition is the one closest to my heart, consisting of the use of institutional categories. Institutions offer practical ways of connecting ideas and people. The challenge for them is the result of deepening local and national interdependencies, but increasingly often also regional (e.g. European and global. Interdependencies are the result of the scientifi c and technological revolution, global markets, global governance mechanisms, the emergence of new social forces and cultural confl icts (against the background of reconciling identity and differences.Conclusions: The most important task is to identify the mechanisms of complex systems so that people know how to act under conditions of uncertainty, risk and crisis. Hence, the expectations toward institutions often exceed their abilities. Even though new institutions are being created and old ones are being fixed, we are witnessing and participating in, institutional paralysis and the decay (e.g. corruption. In this situation, it is imperative not only to

  11. Early modern mathematical instruments.

    2011-12-01

    In considering the appropriate use of the terms "science" and "scientific instrument," tracing the history of "mathematical instruments" in the early modern period is offered as an illuminating alternative to the historian's natural instinct to follow the guiding lights of originality and innovation, even if the trail transgresses contemporary boundaries. The mathematical instrument was a well-defined category, shared across the academic, artisanal, and commercial aspects of instrumentation, and its narrative from the sixteenth to the eighteenth century was largely independent from other classes of device, in a period when a "scientific" instrument was unheard of.

    Pierangelo Schiera

    2016-12-01

    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.

    O'Hara, John

    2004-01-01

    Most nuclear plants were designed and built from the 1960's through the 1990's. These plants employ predominantly analog instrumentation and control (I and C) technology, and their control rooms are made up of primarily hardwired controls (e.g., switches, knobs and handles) and displays (e.g., gauges, linear scales and indicator lights). Over the past several years, these plants have been modernized with digital I and C and computer-based human-system interfaces (HSIs) such as software-based process controls, touch-screen interfaces and large-screen, overview displays. As these computer based HIS technologies are integrated into control rooms based on conventional technology, hybrid control rooms are created. The paper summarizes lessons learned from the study of plant modernization programs over the past ten years so that they can be used to help improve the modification process. While the research focused on the impact of technology change on human performance, a number of organizational and programmatic issues were observed as well. Eleven lessons learned are presented

    Holbrow, Charles H; Amato, Joseph C; Galvez, Enrique; Parks, M. Elizabeth

    2010-01-01

    Modern Introductory Physics, 2nd Edition, by Charles H. Holbrow, James N. Lloyd, Joseph C. Amato, Enrique Galvez, and Beth Parks, is a successful innovative text for teaching introductory college and university physics. It is thematically organized to emphasize the physics that answers the fundamental question: Why do we believe in atoms and their properties?  The book provides a sound introduction to basic physical concepts with particular attention to the nineteenth- and twentieth-century physics underlying our modern ideas of atoms and their structure.  After a review of basic Newtonian mechanics, the book discusses early physical evidence that matter is made of atoms.  With a simple model of the atom Newtonian mechanics can explain the ideal gas laws, temperature, and viscosity.  Basic concepts of electricity and magnetism are introduced along with a more complicated model of the atom to account for the observed electrical properties of atoms. The physics of waves---particularly light and x-rays---an...

  18. The Multiple Modernities of Europe

    DEFF Research Database (Denmark)

    Thomassen, Bjørn

    What Europe? Eric Voegelin on the Mediterranean and the Atlantic modernities. The concept ‘multiple modernities’ has during the last decade established itself in social and political theory, not least due to contributions made by Shmul Eisenstadt. The debate on multiple moderntities has served...... to question certain eurocentric assumptions about modernity and has also reignited the question of European particularity in a world historical perspective. This paper will discuss how ‘Europe’ itself can be considered a result of (at least) two different modernities, as proposed by the political theorist......, Eric Voegelin. Eric Voegelin talked of two spatio-temporal specific modernities, the Mediterranean and the Atlantic modernities. In short, for Voegelin the Atlantic modernity with its breakthroughs in the 17th and 18th centuries was a specific figuration that should not be mistaken for ‘modernity...

    2010-01-01

    This article deals with the concept of modernity upon which one of the most interesting contemporary theories about modern social change is based - Peter Wagner's theory of successive modernities. Wagner understands modernity as a double imaginary signification which entails a basic tension between...... liberty and discipline. This conception is almost directly taken from Cornelius Castoriadis. I argue that this tension exists in two versions in Castoriadis' philosophy and that the two versions are incompatible. It is further claimed that the two versions reappear in Wagner's theory, which makes his...... theory of successive modernities partly inconsistent. A stance is taken for one of these versions and it is argued that the theory of successive modernities should appropriate that version as its point of departure in order to grasp the history of modernity in a consistent way.

    2015-12-01

    Full Text Available Janet T. Marquardt’s book ‘Zodiaque. Making medieval art modern’ discusses the historical context, history and impact of the Zodiaque publications issued by the monks from the abbey of Ste-Marie de la Pierre-qui-Vire in Burgundy between 1951 and 2001 and links the striking photogravures, the core business of these books, to the modern movement. Although Marquardt’s view that the Zodiaque series made a great impact on the study of Romanesque sculpture is somewhat overrated, her claim that the photogravures should be seen as avant-garde works of art and the books as a “museum without walls” is entirely convincing.

  2. Introduction to modern magnetohydrodynamics

    CERN Document Server

    Galtier, Sébastien

    2016-01-01

    Ninety-nine percent of ordinary matter in the Universe is in the form of ionized fluids, or plasmas. The study of the magnetic properties of such electrically conducting fluids, magnetohydrodynamics (MHD), has become a central theory in astrophysics, as well as in areas such as engineering and geophysics. This textbook offers a comprehensive introduction to MHD and its recent applications, in nature and in laboratory plasmas; from the machinery of the Sun and galaxies, to the cooling of nuclear reactors and the geodynamo. It exposes advanced undergraduate and graduate students to both classical and modern concepts, making them aware of current research and the ever-widening scope of MHD. Rigorous derivations within the text, supplemented by over 100 illustrations and followed by exercises and worked solutions at the end of each chapter, provide an engaging and practical introduction to the subject and an accessible route into this wide-ranging field.

  3. Parallelization in Modern C++

    CERN Multimedia

    CERN. Geneva

    2016-01-01

    The traditionally used and well established parallel programming models OpenMP and MPI are both targeting lower level parallelism and are meant to be as language agnostic as possible. For a long time, those models were the only widely available portable options for developing parallel C++ applications beyond using plain threads. This has strongly limited the optimization capabilities of compilers, has inhibited extensibility and genericity, and has restricted the use of those models together with other, modern higher level abstractions introduced by the C++11 and C++14 standards. The recent revival of interest in the industry and wider community for the C++ language has also spurred a remarkable amount of standardization proposals and technical specifications being developed. Those efforts however have so far failed to build a vision on how to seamlessly integrate various types of parallelism, such as iterative parallel execution, task-based parallelism, asynchronous many-task execution flows, continuation s...

    Natarajan, Vasant

    2015-01-01

    Much of our understanding of physics in the last 30-plus years has come from research on atoms, photons, and their interactions. Collecting information previously scattered throughout the literature, Modern Atomic Physics provides students with one unified guide to contemporary developments in the field. After reviewing metrology and preliminary material, the text explains core areas of atomic physics. Important topics discussed include the spontaneous emission of radiation, stimulated transitions and the properties of gas, the physics and applications of resonance fluorescence, coherence, cooling and trapping of charged and neutral particles, and atomic beam magnetic resonance experiments. Covering standards, a different way of looking at a photon, stimulated radiation, and frequency combs, the appendices avoid jargon and use historical notes and personal anecdotes to make the topics accessible to non-atomic physics students. Written by a leader in atomic and optical physics, this text gives a state-of-the...

    Antonio T. Díaz-Royo

    1995-07-01

    Full Text Available [First paragraph in part] The buildings and ruins we discover for ourselves hold a lasting place in our imagination, not to say in our affections. In a society that has neglected the formal treatment of "space," architecturally as well as in political terms, these personal discoveries can promote a subversion of sorts. Thus, the consecutive appearance of two volumes addressing the architecture produced at the turn of the century in Puerto Rico is a notable event. Each results from an architect's passionate concern with the advent of modernity. Thomas Marvel's book concentrates on the life and work of Antonin Nechodoma, an American of Bohemian origin who spent his most productive years in Puerto Rico. It is the result of his decades-long fascination with a "versatile architect, designer, and craftsman working in unusual circumstances" (p. xviii who left, both in Puerto Rico and in the Dominican Republic, a string of edifices strangely echoing the continental Prairie School.

    In this chapter the authors first briefly review the kinetics of first- and second-order processes for continuous and pulsed irradiation, without taking the effects of nonhomogeneous formation of the species into consideration. They also discuss diffusion controlled reactions under conditions where interactions of more than two particles can be neglected, first the kinetics of the diffusion-controlled reaction of randomly generated species (homogeneous reaction) and then that of isolated pairs of reactants. The latter is often called geminate kinetics when dealing with pairs of oppositely charged species; they shall use this term for the kinetics of isolated pairs in general. In the last section they discuss briefly the kinetics of groups of more than two reactants

    2015-02-01

    Full Text Available The history of modern Chinese Buddhism has begun to attract attention in recent years. Some scholars have done inspiring research as they unravel the integration of Buddhism into the highly secularized process of Chinese modernity by drawing on the repository of knowledge on modern China. While this special issue joins this exciting endeavor, it also uses Buddhism as a window to reflect on scholarship on Chinese modernity. Conceptually, this special issue presses scholars in the field of modern China to rethink the place of tradition in the course of modernity. Thematically we show the expansionist impulse of Chinese Buddhism: In addition to envisioning the geographical expansion of their religion, Chinese Buddhists have endeavored to enhance the significance of Buddhism in various dimensions of Chinese society in particular and human life in general.

    Thompson, M.O.; Aziz, M.J.; Stephenson, G.B.

    1992-01-01

    This volume contains papers presented at the Materials Research Society symposium on Kinetics of Phase Transformations held in Boston, Massachusetts from November 26-29, 1990. The symposium provided a forum for research results in an exceptionally broad and interdisciplinary field. Presentations covered nearly every major class of transformations including solid-solid, liquid-solid, transport phenomena and kinetics modeling. Papers involving amorphous Si, a dominant topic at the symposium, are collected in the first section followed by sections on four major areas of transformation kinetics. The symposium opened with joint sessions on ion and electron beam induced transformations in conjunction with the Surface Chemistry and Beam-Solid Interactions: symposium. Subsequent sessions focused on the areas of ordering and nonlinear diffusion kinetics, solid state reactions and amorphization, kinetics and defects of amorphous silicon, and kinetics of melting and solidification. Seven internationally recognized invited speakers reviewed many of the important problems and recent results in these areas, including defects in amorphous Si, crystal to glass transformations, ordering kinetics, solid-state amorphization, computer modeling, and liquid/solid transformations

    Boltzmann and Vlasov equations played a great role in the past and still play an important role in modern natural sciences, technique and even philosophy of science. Classical Boltzmann equation derived in 1872 became a cornerstone for the molecular-kinetic theory, the second law of thermodynamics (increasing entropy) and derivation of the basic hydrodynamic equations. After modifications, the fields and numbers of its applications have increased to include diluted gas, radiation, neutral particles transportation, atmosphere optics and nuclear reactor modelling.

  16. Zeno Meets Modern Science

    Science.gov (United States)

    Silagadze, Z. K.

    2005-10-01

    ``No one has ever touched Zeno without refuting him''. We will not refute Zeno in this paper. Instead we review some unexpected encounters of Zeno with modern science. The paper begins with a brief biography of Zeno of Elea followed by his famous paradoxes of motion. Reflections on continuity of space and time lead us to Banach and Tarski and to their celebrated paradox, which is in fact not a paradox at all but a strict mathematical theorem, although very counterintuitive. Quantum mechanics brings another flavour in Zeno paradoxes. Quantum Zeno and anti-Zeno effects are really paradoxical but now experimental facts. Then we discuss supertasks and bifurcated supertasks. The concept of localisation leads us to Newton and Wigner and to interesting phenomenon of quantum revivals. At last we note that the paradoxical idea of timeless universe, defended by Zeno and Parmenides at ancient times, is still alive in quantum gravity. The list of references that follows is necessarily incomplete but we hope it will assist interested reader to fill in details.

    Going into the next millennium do we see nuclear energy? Yes we will see an expanding nuclear sector in the modem community. he modem community that cares for people, health and environment needs nuclear. Energy saves lives. Electricity is efficient use of energy. Energy will be the key to a sustainable society, energy is life. Nuclear energy protects the environment. Nuclear is an integral part of the modern community caring for people, health and environment. The dynamics of the public opinion-forming process and its effects on the nuclear industry are a challenge of the global nuclear industry. Current communications strategy and its consequences are on of the key issues. The nuclear industry must be perceived in certain ways in order to move towards achieving the vision and avoiding the harassment scenario. Each perception goal does not bear the same function within the communications process. As the nuclear industry is oe of the keys to a sustainable society, it must achieve legitimacy in its capacity as an interesting agenda-setter for tackling problems and as an expert. We have to build our communication activities on an open and honest attitude and we have to establish trust and confidence. The nuclear industry must also prove its ability and performance. If this could be achieved there will be an option for the future

    1998-01-01

    The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole. This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. The volume grew out of the author's earlier book, Graph Theory -- An Introductory Course, but its length is well over twice that of its predecessor, allowing it to reveal many exciting new developments in the subject. Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory such as coloring, matching, extremal theory, and algebraic graph theory, the book presents a detailed ...

    2015-01-01

    We demonstrate the first implementation of recently-developed fast explicit kinetic integration algorithms on modern graphics processing unit (GPU) accelerators. Taking as a generic test case a Type Ia supernova explosion with an extremely stiff thermonuclear network having 150 isotopic species and 1604 reactions coupled to hydrodynamics using operator splitting, we demonstrate the capability to solve of order 100 realistic kinetic networks in parallel in the same time that standard implicit methods can solve a single such network on a CPU. This orders-of-magnitude decrease in computation time for solving systems of realistic kinetic networks implies that important coupled, multiphysics problems in various scientific and technical fields that were intractable, or could be simulated only with highly schematic kinetic networks, are now computationally feasible.

    2005-01-01

    Full Text Available The question whether freedom of religion requires permitting the slaughter of animals in accordance with Islamic rites – a question which was the subject of a decision by the German Federal Constitutional Court in 2002 –is an example of the general problem how the law and the constitution of a modern, secular society can deal with the Sharia, a theonomous law which claims authority by divine revelation. The genetic links between western christianity and the development of the foundations of modern society in Europe do not provide evidence of the incompatibility of Islam and modernity. But they do emphasize that the tensions resulting from the immigration of 3 million muslims in Germany are a great challenge for the constitutional order. A modern constitution of the Western European and North-Atlantic type, such as the german constitution (Grundgesetz, does not allow the dissolution of the tensions between secular law and individual religious autonomy unilaterally in favour of the secular law. This kind of tension is by no means unknown in modern society. Functional differentiation and individualization are core characteristics of modern society. But in view of the challenge by Islam and other challenges, such as ecological problems, we can ask if the »experiment in modernity«, the project of the Enlightenment, is destined to fail because of the dissonance and the lack of understanding between the partial systems of the society. This question is the starting point to outline evolutionary processes of integration in modern society. In this context the constitution proves to be an important tool of integration. Controversies about the scope of validity claimed by the partial systems are matters of constitutional law. The modern constitution is a specific form in which modern society describes itself as a unity insuring »practical concordance« between colliding freedoms and claims of validity. In the conflict of modern ethical principles of

  10. BOOK REVIEW: Modern Supersymmetry

    Science.gov (United States)

    Kulish, Petr P.

    2006-12-01

    We have spent more than twenty years applying supersymmetry (SUSY) to elementary particle physics and attempting to find an experimental manifestation of this symmetry. Terning's monograph demonstrates the strong influence of SUSY on theoretical elaborations in the field of elementary particles. It gives both an overview of modern supersymmetry in elementary particle physics and calculation techniques. The author, trying to be closer to applications of SUSY in the real world of elementary particles, is also anticipating the importance of supersymmetry for rigorous study of nonperturbative phenomena in quantum field theory. In particular, he presents the `exact' SUSY β function using instanton methods, phenomena of anomalies and dualities. Supersymmetry algebra is introduced by adding two anticommuting spinor generators to Poincaré algebra and by presenting massive and massless supermultiplets of its representations. The author prefers to use mostly the component description of field contents of the theories in question rather than the superfield formalism. Such a style makes the account closer to physical chartacteristics. Relations required by SUSY among β functions of the gauge, Yukawa and quartic interactions are checked by direct calculations as well as to all orders in perturbation theory, thus demonstrating that SUSY survives quantization. A discussion is included of the hierarchy problem of different scales of weak and strong interactions and its possible solution by the minimal supersymmetric standard model. Different SUSY breaking mechanisms are presented corresponding to a realistic phenomenology. The monograph can also be considered as a guide to `duality' relations connecting different SUSY gauge theories, supergravities and superstrings. This is demonstrated referring to the particular properties and characteristics of these theories (field contents, scaling dimensions of appropriate operators etc). In particular, the last chapter deals with the Ad

  11. Interpreted Modernity. Weber and Taylor on Values and Modernity

    OpenAIRE

    2001-01-01

    The writings of Weber and Taylor have some strong affinities. Both start from the anthropological idea that man evaluates his position in the world and constitutes the social world by values. Their analyses of values aim at an understanding of those intersubjective meanings that have constituted western modernity. But, at the same time, their anthropological starting point leads to different interpretations of modernity. Historically, both argue that rationalization (as instrumental rationali...

  12. Postmodernism in Belgrade architecture: Between cultural modernity and societal modernization

    Directory of Open Access Journals (Sweden)

    Blagojević Ljiljana

    2011-01-01

    Full Text Available The paper explores the introduction and articulation of ideas and aesthetic practice of postmodernism in architecture of late socialism in Yugoslavia, with the focus on Belgrade architecture scene. Theoretical and methodological point of departure of this analysis is Jürgen Habermas's thesis of modernity as an incomplete, i.e., unfinished project, from his influential essay “Die Moderne: Ein unvollendetes Projekt” (1980. The thematic framework of the paper is shifted towards issues raised by Habermas which concern relations of cultural modernity and societal modernization, or rather towards consideration of architectural postmodernity in relation to the split between culture and society. The paper investigates architectural discourse which was profiled in Belgrade in 1980s, in a historical context of cultural modernity simultaneous with Habermas's text, but in different conditions of societal modernization of Yugoslav late socialism. In that, the principle methodological question concerns the interpretation of postmodern architecture as part of the new cultural production within the social restructuration of late and/or end of socialism as a system, that being analogous to Fredric Jameson's thesis of “Postmodernism, Or, The Cultural Logic of Late Capitalism” (1984.

    2015-01-01

    This textbook provides a unified and self-contained presentation of the main approaches to and ideas of mathematical statistics. It collects the basic mathematical ideas and tools needed as a basis for more serious studies or even independent research in statistics. The majority of existing textbooks in mathematical statistics follow the classical asymptotic framework. Yet, as modern statistics has changed rapidly in recent years, new methods and approaches have appeared. The emphasis is on finite sample behavior, large parameter dimensions, and model misspecifications. The present book provides a fully self-contained introduction to the world of modern mathematical statistics, collecting the basic knowledge, concepts and findings needed for doing further research in the modern theoretical and applied statistics. This textbook is primarily intended for graduate and postdoc students and young researchers who are interested in modern statistical methods.

    Full Text Available Research shows that maintaining high individual modernity level can enable the shaping of positive self-image and boost life satisfaction for older people along with better adaptation to the process of societal modernization. This study examined the factorial structure and evaluated the psychometric properties of the adapted Multidimensional Scale of Chinese Individual Modernity (MS-CIM in a sample of 445 elders (the finalized version is named “MS-CIME” and added a self-constructed nine-item behavioral modernity domain. Principal component analysis suggested a conceptually meaningful seven-factor model, which was further supported by the results of the confirmatory factor analysis (CFA. The final 25-item MS-CIME indicated an acceptable level of reliability. The convergent validity was demonstrated by its associations with socio-economic status, participation in daily activities, self-image, and life satisfaction in expected directions.

    Ferrizz, Robert Matthew

    2006-11-01

    Thermal desorption spectroscopy (TDS) is used to study the decomposition kinetics of erbium hydride thin films. The TDS results presented in this report are analyzed quantitatively using Redhead's method to yield kinetic parameters (E{sub A} {approx} 54.2 kcal/mol), which are then utilized to predict hydrogen outgassing in vacuum for a variety of thermal treatments. Interestingly, it was found that the activation energy for desorption can vary by more than 7 kcal/mol (0.30 eV) for seemingly similar samples. In addition, small amounts of less-stable hydrogen were observed for all erbium dihydride films. A detailed explanation of several approaches for analyzing thermal desorption spectra to obtain kinetic information is included as an appendix.

    2016-01-01

    This book presents quantum kinetic theory in a comprehensive way. The focus is on density operator methods and on non-equilibrium Green functions. The theory allows to rigorously treat nonequilibrium dynamics in quantum many-body systems. Of particular interest are ultrafast processes in plasmas, condensed matter and trapped atoms that are stimulated by rapidly developing experiments with short pulse lasers and free electron lasers. To describe these experiments theoretically, the most powerful approach is given by non-Markovian quantum kinetic equations that are discussed in detail, including computational aspects.

    Directory of Open Access Journals (Sweden)

    Kros Džonatan

    2006-01-01

    Full Text Available Conventionally, the story of musical modernism has been told in terms of a catastrophic break with the (tonal past and the search for entirely new techniques and modes of expression suitable to a new age. The resulting notion of a single, linear, modernist mainstream (predicated on the basis of a Schoenbergian model of musical progress has served to conceal a more subtle relationship between past and present. Increasingly, it is being recognized that there exist many modernisms and their various identities are forged from a continual renegotiation between past and present, between tradition(s and the avant-garde. This is especially relevant when attempting to discuss the reception of modernism outside central Europe, where the adoption of (Germanic avant-garde attitudes was often interpreted as being "unpatriotic". The case of Great Britain is examined in detail: Harrison Birtwistle’s opera The Mask of Orpheus (1973–83 forms the focus for a wider discussion of modernism within the context of late/post-modern thought.

  6. On Heidegger, medicine, and the modernity of modern medical technology.

    Science.gov (United States)

    Brassington, Iain

    2007-06-01

    This paper examines medicine's use of technology in a manner from a standpoint inspired by Heidegger's thinking on technology. In the first part of the paper, I shall suggest an interpretation of Heidegger's thinking on the topic, and attempt to show why he associates modern technology with danger. However, I shall also claim that there is little evidence that medicine's appropriation of modern technology is dangerous in Heidegger's sense, although there is no prima facie reason why it mightn't be. The explanation for this, I claim, is ethical. There is an initial attraction to the thought that Heidegger's thought echoes Kantian moral thinking, but I shall dismiss this. Instead, I shall suggest that the considerations that make modern technology dangerous for Heidegger are simply not in the character - the ethos - of medicine properly understood. This is because there is a distinction to be drawn between chronological and historical modernity, and that even up-to-date medicine, empowered by technology, retains in its ethos crucial aspects of a historically pre-modern understanding of technology. A large part of the latter half of the paper will be concerned with explaining the difference.

The kinetic modeling approach in this work initially targets the scope of the generation of a superstructure of micro-kinetic reaction schemes and models assuming Langmuir-Hinshelwood (LH) and Eley-Rideal (ER) mechanisms. Subsequently, the screening and selection of above models is initially based on profile-based elimination of incompetent schemes followed by non-linear regression search performed using the Levenberg-Marquardt algorithm (LMA) for the chosen models. The above analysis inferred that Eley-Rideal mechanism describes the kinetic behavior of ODS process using tungsten-containing LDH, with adsorption of reactant and intermediate product only taking place on the catalyst surface. Finally, an economic index is presented that scopes the economic aspects of the novel catalytic technology with the parameters obtained during regression analysis to conclude that the cost factor for the catalyst is 0.0062-0.04759 US $ per barrel.

    1990-12-01

    This report was prepared by the Pacific Northwest Laboratory to summarize existing and emerging information system technology and standards applicable to Depot System Command (DESCOM) modernization efforts. The intent of this summarization is to provide the Revitalization of Army Depots for the Year 2000 (READY 2000) team a clear understanding of the enabling information system technologies required to support effective modernization activities. Much of the information contained in this report was acquired during the last year in support of the US Army Armament, Munitions, and Chemical Command (AMCCOM) Facility Integrated Manufacturing Management System (FIMMS) project at PNL, which is targeting the modernization of plant-wide information systems at Army Ammunition Plants. The objective of information system modernization is to improve the effectiveness of an organization in performing its mission. Information system modernization strives to meet this objective by creating an environment where data is electronically captured near the source and readily available to all areas of the organization. Advanced networks, together with related information system technology, are the enabling mechanisms that make modern information system infrastructures possible. The intent of this paper is to present an overview of advanced information system network technology to support depot modernization planners in making technology management decisions. Existing and emerging Open System Interconnection (OSI) and Government Open System Interconnection Profile (GOSIP) standards are explained, as well as a brief assessment of existing products compliant with these standards. Finally, recommendations for achieving plant-wide integration using existing products are presented, and migration strategies for full OSI compliance are introduced. 5 refs., 16 figs. (JF)

  16. Montreal Modern: Retro Culture and the Modern Past in Montreal

    Directory of Open Access Journals (Sweden)

    Kristian Handberg

    2015-03-01

    Full Text Available Through analyses of the retro scenes in Montreal, Canada, the article discusses retro culture's role as cultural memory. It is shown how Montreal's cultural identity is formed by memories of modern culture such as the Red-light and Sin City reputation of the illicit nightlife of the 1940s and 1950s, and the space age modernism of the 1960s following the Expo 67 and Quebec's Quiet Revolution. This is reflected in the city's thriving retro culture through the study of two groups of retro shops. In circulating specific memories and objects in a specific context, retro is an important negotiation of the past in the present. Especially, it is stated that the retro culture displays "local accents" and a new focus on the specificities of modern culture giving a revaluation to a previously overlooked identity such as the Quebecit.

  17. Gellnerovo pojetí modernity

    Directory of Open Access Journals (Sweden)

    Jiří Musil

    2017-10-01

    Full Text Available Gellner’s theory of modernity is a complex structure, it matured several decades and during this process he modified some of its elements. The following interpretation of his theory is based on the analysis of three pillars of his thought, first on his epistemological axioms, second on his concept of philosophy of human history and third on his conception of social theory. Gellner’s theory of knowledge is a cluster composed of classical empiricism, kantian rationalism, enriched by weberian understanding of historical modifications of rationalism in modern times. Gellner adds to these two pillars his concept of cultural perspectivism and his interpretation of evolutionism, so called truncated evolutionism that concentrates on the emergence of modernity. Gellner’s philosophy of history is based on his analysis of interaction between three basic functional entities of all human societies: economy, power, knowledge. Gellner rather carefully analyzed as well the relationship between the role of material and ideational factors in human history, and between sociological analyses based on causal. In his view sociology has to use both approaches. Gellner is stressing the fact that to the most important elements of modernity belongs science, but at the same time he is fully aware of the fact that science can not tell us “what to do”. Here he follows Max Weber’s thesis on the disenchantment as an element of modernity.

On the one hand, the issue of sustainability is linked to art museums inasmuch these institutions operate for the sustainable...... to their eligibility for funding and it is indeed an economic rather than a cultural issue. Though, modern art museums’ sustainability relies not only in developing economic and environmental strategies but mostly in creating cultural policies that favor art museums in accomplishing same tasks but from different...... curatorial and managerial perspectives. A long-term sustainable museum model steps beyond Foucault’s notion that art museums are “heterotopy”, i.e. spaces that present art as an alternative phenomenon outside reality. On the contrary, a sustainable model for museums acts as “archètopy”, i.e. a space (tòpos...

    This book explores the modern role of measurement science for both the technically most advanced applications and in everyday and will help readers gain the necessary skills to specialize their knowledge for a specific field in measurement. Modern Measurements is divided into two parts. Part I (Fundamentals) presents a model of the modern measurement activity and the already recalled fundamental bricks. It starts with a general description that introduces these bricks and the uncertainty concept. The next chapters provide an overview of these bricks and finishes (Chapter 7) with a more general and complex model that encompasses both traditional (hard) measurements and (soft) measurements, aimed at quantifying non-physical concepts, such as quality, satisfaction, comfort, etc. Part II (Applications) is aimed at showing how the concepts presented in Part I can be usefully applied to design and implement measurements in some very impor ant and broad fields.

Now, in the 21st century, the library is facing perhaps the biggest challenge – its physical survival. The role of librarians is re-branded to reflect their expertise as curators of content and reliable navigators in an evergrowing ocean of information - in any format they might exist. The future libraries shall be open to all the new ideas on how to work better and accept the new technologies. On the one hand, they must recognize the need to change their methods, but on the other hand - to preserve the continuity of their objectives and mission. The new era requires modern models of learning and the attractiveness of the curricula, that is, a modern education system that shall adapt the curricula to the needs of modern society and reconcile centuries of man's need for knowledge, reading books and education in general with the new technologies.

    These notes are the content of an introductory course on modern, coordinate-free differential geometry which is taken by the first-year theoretical physics PhD students, or by students attending the one-year MSc course "Fundamental Fields and Forces" at Imperial College. The book is concerned entirely with mathematics proper, although the emphasis and detailed topics have been chosen with an eye to the way in which differential geometry is applied these days to modern theoretical physics. This includes not only the traditional area of general relativity but also the theory of Yang-Mills fields

  5. AYURVEDA AND MODERN HEALTH EDUCATION

    Ayurveda is prevention in itself. It is not necessary for Ayurveda to develop a comprehensive structure of preventive approaches as it is found in modern health education. On the other hand has Ayurveda not modernized its preventive principles according to the present living and working conditions of the people. It is so far not understood as integral part of the socio-economic development of the country. This has saved Ayurveda to become part of the highly structured and bureaucratic form of health care and health education- at the expense of not being consulted by others when working on a social health oriented development strategy.

Strategies have included foregrounding the plurality of history to disrupt linear progress; positing non-Western centers of modernity in, say, Moscow or Shanghai; and tracing anticolonial circuits connecting Asia to Africa to Latin America. The two recent books under review here add colonial-era Korea to such far-reaching discussions by situating the country across national boundaries. Interestingly, one connecting thread here is the alternative world system provided by the interwar, Soviet-oriented Left. The result is an unsettling of binaries that subsequently became entrenched during the Cold War: for example, north-south, socialist-nationalist, and, for literature, realist-modernist. But more broadly, pervading both books is the sense that history could have turned out differently—that revisiting northeast Asia’s porous borders in the early twentieth century reveals the Korean peninsula’s lost, internationalist potential...

    2016-12-01

    A geological buffer for high atmospheric CO2 concentrations is neutralization via reaction with CaCO3. We have been studying the dissolution kinetics of carbonate minerals using labeled 13C calcite and Picarro-based measurements of 13C enrichments in solution DIC. This methodology has greatly facilitated our investigation of dissolution kinetics as a function of water carbonate chemistry, temperature and pressure. One can adjust the saturation state Omega by changing the ion activity product (e.g. adjusting carbonate ion concentration), or by changing the solubility product (e.g. adjusting temperature or pressure). The canonical formulation of dissolution rate vs. omega has been refined (Subhas et al. 2015) and shows distinct non-linear behavior near equilibrium and rates in sea water of 1-3 e-6 g/cm2day at omega = 0.8. Carbonic anhydrase (CA), an enzyme that catalyzes the hydration of dissolved CO2 to carbonic acid, was shown (in concentrations 500x. This result points to the importance of carbonic acid in enhancing dissolution at low degrees of undersaturation. CA activity and abundance in nature must be considered regarding the role it plays in catalyzing dissolution. We also have been investigating the role of temperature on dissolution kinetics. An increase of 16C yields an order of magnitude increase in dissolution rate. Temperature (and P) also change Omega critical, the saturation state where dissolution rates change substantially. Increasing pressure (achieved in a pressure reaction chamber we built) also shifts Omega critical closer to equilibrium and small pressure increases have large impact on dissolution kinetics. Dissolution rates are enhanced by an order of magnitude for a change in pressure of 1500 psi relative to the dissolution rate achieved by water chemistry effects alone for an omega of 0.8. We've shown that the thermodynamic determination of saturation state does not adequately describe the kinetics of dissolution. The interplay of mineral

The author concludes that the various components of the religious consciousness of the Japanese were kontratetycal on two main elements that form the basis of modern Western culture Japanese resistance and cause upgrade. First, science and technology, working on the basis of the laws of nature, which are opposed to the supernatural and the metaphysical world. Secondly, expressed individualism and atomism as hypertrophic respect for the human person, liberal nadzoseredzhenist to a person who undermines the consolidation of corporate social society. Japanese culture in the past was oriented toward modernization, but progress has been very slow. Moreover, in this process, Japan was much more conservative because in Japanese society regulatory institutions of the army, religion and industrial corporations can be considered a kind of constants which not only can be adapted to the modernization of Euro-American style, as suggested selection of authentic script compatible, especially with life values corporatism and solidarity. It is in this dimension of modernization projects related to Christian proselytism, as were «frustrated.» The reason for this breakdown can be considered inherence religion with social cohesion, its actual merging of social institutions, as well as hidden mahizm skepticism and religious outlook that combines Shinto, Confucian and Zen Buddhist elements. Since modernization in Christianity included the distinction darkened minds clerical era and «enlightened enlightenment» of consciousness era of modern times, it is this dichotomy allowed to oppose religious «ignorance» and scientific «enlightenment», the clergy and secular intellectuals, universities and intellectual clubs as a medium spreading the ideology of the bourgeoisie and monasteries as centers of religious clericalism

  17. Kinetics of tetrataenite disordering

    International Nuclear Information System (INIS)

    Dos Santos, E.; Gattacceca, J.; Rochette, P.; Fillion, G.; Scorzelli, R.B.

    2015-01-01

    Tetrataenite is a chemically ordered L1 0 -type Fe 50 Ni 50 alloy detected for the first time in 1977 by 57 Fe Mössbauer spectroscopy studies in iron meteorites. The thermal history of meteorites, in particular short thermal events like those associated to hypervelocity impacts, can be constrained by tracing the presence of tetrataenite or its disordering into taenite. The knowledge of the disordering kinetics of tetrataenite, that is associated with changes in its magnetic properties, is still very fragmentary so that the time–temperature history of these meteorites cannot be constrained in details. Furthermore, knowledge of disordering kinetics is important due to potential technological application of tetrataenite as a rare-earth free strong magnet. Thus, this work provides the first time–temperature data for disordering reaction of tetrataenite. We have shown that disordering is not an instantaneous process but is a kinetic limited reaction. It was shown that disordering may take place at any temperature above the order–disorder transition for L 10 superstructure phase (∼320 °C) when the appropriate time-scale is considered. This result means that the apparent Curie point for tetrataenite is not an absolute property in the sense that any estimate of this parameter should be referred to a given time-scale. - Highlights: • The first time–temperature data for tetrataenite disordering reaction is provided. • Previous works does not give a complete picture of tetrataenite disordering. • Apparent Curie temperature of tetrataenite should be referred to a time-scale. • Tetrataenite can be used as a probe to detect thermal/shock events recorded in meteorites

    In this paper, we introduce a quantum generalization of classical kinetic Ising models (KIM), described by a certain class of quantum many-body master equations. Similarly to KIMs with detailed balance that are equivalent to certain Hamiltonian systems, our models reduce to a set of Hamiltonian systems determining the dynamics of the elements of the many-body density matrix. The ground states of these Hamiltonians are well described by the matrix product, or pair entangled projected states. We discuss critical properties of such Hamiltonians, as well as entanglement properties of their low-energy states.

    The most important innovation stages of electronic I and C systems are summarized. The TELEPERM XS serves as the example to demonstrate the design of modern I and C systems as well as the use of computer-based tools. The paper explains the conditions of use of these tools during future system operation. By a comparative evaluation it is shown that the modernization of I and C systems brings not only increased reliability but also essential simplifications in operation as well as cost savings. Typical applications of the TELEPERM XS are in safety systems for reactor protection, and in the Engineered Safety Feature Actuation System. This is why, in conclusion, the author briefly refers to the design-based protection against systematic failures, which is a requirement of the nuclear safety engineering codes. (orig./CB) [de

    2009-01-01

    The very presence of myths in psychoanalysis raises questions about their scientific status: that leads to reconsider the whole issue of Freudian mythology in a non-medical manner, by envisaging it in the more general context of modern myths, both political and artistic. Special attention is then paid to Surrealism, as the only avant-garde movement at the same time focused on psychoanalysis and politics: the role played by dreams in foundering myths is examined in both Surrealism and psychoanalysis. Surrealistic myths, such as Dalí's Grand Paranoïaque Comestible, finally prove to be so non-oedipian as the Nazi Ubermensch myth; nevertheless, their comparison with Freudian mythology points out their common origin, as they all fulfilled the need of the mass society for a modern myth, able to express his deeply renewed self-awareness.

    Max Planck (1858-1947) is according to the words of Max von Laue the ''father of quantum physics''. This characteristic has until today continuance, although Planck stood for long time sceptically in front of his quantum hypothesis and so became a revolutionary in spite of his wishes. Eclipted by this pioneer role of the scholar for the foundation of the quantum theory are the numerous further works of the scholer, by which he has in many other fields provided eminent things. Starting with his fundamental contribution to thermodynamics, which make him to an excellent researcher of the field, until the works in the early history of relativity theory and the promotion of the young Einstein, which let him become also to a pioneer of the second central pillar of modern physics. The present collection attempts to show the whole spectrum of the physical works of Max Planck and his role in the formation of modern physics. [de

    2009-01-01

    With the aim of presenting thermodynamics in as simple and as unified a form as possible, this textbook starts with an introduction to the first and second laws and then promptly addresses the complete set of the potentials in a subsequent chapter and as a central theme throughout. Before discussing modern laboratory measurements, the book shows that the fundamental quantities sought in the laboratory are those which are required for determining the potentials. Since the subjects of thermodynamics and statistical mechanics are a seamless whole, statistical mechanics is treated as integral part of the text. Other key topics such as irreversibility, the ideas of Ilya Prigogine, chemical reaction rates, equilibrium of heterogeneous systems, and transition-state theory serve to round out this modern treatment. An additional chapter covers quantum statistical mechanics due to active current research in Bose-Einstein condensation.

    Rajaraman, R.

    1979-01-01

    Modern applications of the ideas of phase transitions to nuclear systems and the modern techniques as applied to familiar phase transitions in solid-state physics are discussed with illustrations. The phenomenon of pion condensation in nuclei and neutron stars, is presented as an example of phase transitions in nuclear systems. The central physical ideas behind this subject as well as techniques used to tackle it are broadly summarised. It is pointed out that unlike familiar examples of ferromagnetism or superconductivity, the order parameter here has spatial variation even in the ground state. Possible experimental consequences are discussed. As an example of the second category, the use of renormalisation group techniques in solid state physics is reviewed. The basic idea behind the renormalisation group in the infra-red (thermodynamic) limit is presented. The observed universality and scaling of critical exponents in second order phase transitions is explained in a model-independent way. (auth.)

  7. Modernity and narcissistic personality disorder.

    Science.gov (United States)

    Paris, Joel

    2014-04-01

    Narcissistic personality disorder (NPD) is a trait-based disorder that can be understood as a pathological amplification of narcissistic traits. While temperamental vulnerability and psychological adversity are risk factors for NPD, sociocultural factors are also important. This review hypothesizes that increases in narcissistic traits and cultural narcissism could be associated with changes in the prevalence of NPD. These shifts seem to be a relatively recent phenomenon, driven by social changes associated with modernity. While the main treatment for NPD remains psychotherapy, that form of treatment is itself a product of modernity and individualism. The hypothesis is presented that psychological treatment, unless modified to address the specific problems associated with NPD, could run the risk of supporting narcissism.

Similarly, in the modern era, the hadith remains the object of criticism by not only Muslim intellectuals but also outsiders, such as the West. Western imperialism against the Islamic world in the past was now the beginning of the history of how Muslims are only able to “survive” rather than “attack.” The emergence of defensive and reactive works against trends of the West in criticizing and blasphemed the hadith, then, such works became trends and supporting methodologies among Muslim observers of the hadith in today’s modern era

    In high power, high voltage electronics systems, a strategy to manage short timescale energy imbalances is fundamental to the system reliability. Without a theoretical framework, harmful local convergence of energy can affect the dynamic process of transformation, transmission, and storage which create an unreliable system. With an original approach that encourages understanding of both macroscopic and microscopic factors, the authors offer a solution. They demonstrate the essential theory and methodology for the design, modeling and prototyping of modern power electronics converters to crea

    1989-07-01

    This report contains results of a coordinated, multi-laboratory investigation of coal devolatilization. Data is reported pertaining to the devolatilization for bituminous coals over three orders of magnitude in apparent heating rate (100 to 100,000 + {degree}C/sec), over two orders of magnitude in particle size (20 to 700 microns), final particle temperatures from 400 to 1600{degree}C, heat transfer modes ranging from convection to radiative, ambient pressure ranging from near vacuum to one atmosphere pressure. The heat transfer characteristics of the reactors are reported in detail. It is assumed the experimental results are to form the basis of a devolatilization data base. Empirical rate expressions are developed for each phase of devolatilization which, when coupled to an awareness of the heat transfer rate potential of a particular devolatilization reactor, indicate the kinetics emphasized by a particular system reactor plus coal sample. The analysis indicates the particular phase of devolatilization that will be emphasized by a particular reactor type and, thereby, the kinetic expressions appropriate to that devolatilization system. Engineering rate expressions are developed from the empirical rate expressions in the context of a fundamental understanding of coal devolatilization developed in the course of the investigation. 164 refs., 223 figs., 44 tabs.

  16. Repair kinetics in tissues

    International Nuclear Information System (INIS)

    Thames, H.D.

    1989-01-01

    Monoexponential repair kinetics is based on the assumption of a single, dose-independent rate of repair of sublethal injury in the target cells for tissue injury after exposure to ionizing radiation. Descriptions of the available data based on this assumption have proved fairly successful for both acutely responding (skin, lip mucosa, gut) and late-responding (lung, spinal cord) normal tissues. There are indications of biphasic exponential repair in both categories, however. Unfortunately, the data usually lack sufficient resolution to permit unambiguous determination of the repair rates. There are also indications that repair kinetics may depend on the size of the dose. The data are conflicting on this account, however, with suggestions of both faster and slower repair after larger doses. Indeed, experiments that have been explicitly designed to test this hypothesis show either no effect (gut, spinal cord), faster repair after higher doses (lung, kidney), or slower repair after higher doses (skin). Monoexponential repair appears to be a fairly accurate description that provides an approximation to a more complicated picture, the elucidation of whose details will, however, require very careful and extensive experimental study.

  17. Diffusion Influenced Adsorption Kinetics.

    Science.gov (United States)

    Miura, Toshiaki; Seki, Kazuhiko

    2015-08-27

    When the kinetics of adsorption is influenced by the diffusive flow of solutes, the solute concentration at the surface is influenced by the surface coverage of solutes, which is given by the Langmuir-Hinshelwood adsorption equation. The diffusion equation with the boundary condition given by the Langmuir-Hinshelwood adsorption equation leads to the nonlinear integro-differential equation for the surface coverage. In this paper, we solved the nonlinear integro-differential equation using the Grünwald-Letnikov formula developed to solve fractional kinetics. Guided by the numerical results, analytical expressions for the upper and lower bounds of the exact numerical results were obtained. The upper and lower bounds were close to the exact numerical results in the diffusion- and reaction-controlled limits, respectively. We examined the validity of the two simple analytical expressions obtained in the diffusion-controlled limit. The results were generalized to include the effect of dispersive diffusion. We also investigated the effect of molecular rearrangement of anisotropic molecules on surface coverage.

  3. Post-communism: postmodernity or modernity revisited?

    Science.gov (United States)

    Ray, L

    1997-12-01

    Coinciding with the popularity of postmodern theory, the fall of communism appeared to offer further evidence of the exhaustion of modernity. Such analysis is grounded in a view that the Soviet system was the epitome of modernity. An alternative approach regards post-communism as opening new terrains of struggle for modernity. Thus Habermas and others suggest that post-communist societies are rejoining the trajectory of western modernity whose problems they now recapitulate. This alternative view implies that Soviet systems were something other than 'modern', although their nature is not always clearly defined. However, even if post-communist societies do encounter problems of modernity, they do so in new circumstances where modernist notions of social development have become problematic. This article argues that, contrary to those who regard modernization or postmodernization as irresistible trends, core post-communist societies are likely to develop along an alternative path to that of western modernity. This is tentatively described as 'neo-mercantilist'.

    The Modern Programme and the linear City If a single argument were to be provided for a current review of architecture, modernism and Le Corbusier, it would have to be the concept of sustainable development. Today, there is broad consensus that sustainable development will set the agenda for the 21......st century, and architecture will play a decisive role in this development. The question of sustainability adds modernism to the agenda anew, especially heroic modernism, the circle of CIAM and Le Corbusier, whom from the beginning placed the dwelling and the city in a sustainable framework – a pact...... an unfinished and dynamic project. Modernism is history – and present. We have not yet seen modernism's successor, but note that the question of sustainability contains the potential for the next paradigm shift, the next architectural revolution – with modernism and the modern programme as a good foundation...

    2015-11-01

    Diffusion of information, behavioral patterns or innovations follows diverse pathways depending on a number of conditions, including the structure of the underlying social network, the sensitivity to peer pressure and the influence of media. Here we study analytically and by simulations a general model that incorporates threshold mechanism capturing sensitivity to peer pressure, the effect of "immune" nodes who never adopt, and a perpetual flow of external information. While any constant, nonzero rate of dynamically introduced spontaneous adopters leads to global spreading, the kinetics by which the asymptotic state is approached shows rich behavior. In particular, we find that, as a function of the immune node density, there is a transition from fast to slow spreading governed by entirely different mechanisms. This transition happens below the percolation threshold of network fragmentation, and has its origin in the competition between cascading behavior induced by adopters and blocking due to immune nodes. This change is accompanied by a percolation transition of the induced clusters.

    1984-01-01

    Beginning in the mid to late sixties, most new accelerators were designed to include computer based control systems. Although each installation differed in detail, the technology of the sixties and early to mid seventies dictated an architecture that was essentially the same for the control systems of that era. A mini-computer was connected to the hardware and to a console. Two developments have changed the architecture of modern systems: the microprocessor and local area networks. This paper discusses these two developments and demonstrates their impact on control system design and implementation by way of describing a possible architecture for any size of accelerator.

    A fundamental effort in neurosurgery is to reduce surgical trauma. Microneurosurgical technique combined with precise localization of lesions, can minimize the invasiveness of neurosurgical procedures. This report summarizes the utility of frameless neuronavigator systems and examines their value in reducing operative invasiveness. The basic principle of neuronavigation is the virtual linkage between digitized neuroradiological data and real anatomical structures, allowing an excellent three-dimensional orientation by real-time graphic-anatomic interaction. As frameless graphic interactive neuronavigation is developed further, these devices should become an important component of the modern microneurosurgical armamentarium and reduce surgical morbidity.

    Dyslipidemia is abnormalities of lipid and lipoprotein metabolism. Most dyslipidemias are hyperlipidemias; that is an abnormally high level of lipids and/or lipoproteins in the blood. Lipid and lipoprotein abnormalities are common in the general population, and are regarded as a modifiable risk factor for cardiovascular disease due to their influence on atherosclerosis. Primary dyslipidemia is usually due to genetic causes, while secondary dyslipidemia arises due to other underlying causes such as diabetes mellitus. Thus, dyslipidemia is an important factor in the development of atherosclerosis and cardiovascular diseases therefore, it is important to diagnose it in time. This review focuses on the modern methods of diagnosis of dyslipidemia.

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available The article raises an issue to enhance technological forging capabilities on the known knuckle joint presses. It provides an illustrated overview of main design types of presses with crank-knuckle, toggle-knuckle, and knuckle joint mechanisms. The article also shows the advantages of the modernization way and improvement just of the active press equipment in terms of quality-to-price ratio, for example, as compared to the similar new foreign press equipment.It gives an overview of features, which provide forging processes owing to kinetic energy accumulated with the moving parts of the known designs of the knuckle joint presses depending on the drive actuating mechanism. Focused attention is drawn to forging on the knuckle joint presses for a time of contact with a work piece to be comparable with the duration of the work piece deformation process on hydraulic forging hammers. This allows us to forge thin-wall products with process automation compared to the forging hammers.Analysis of accumulating processes of kinetic energy by the moving parts of the knuckle joint presses has shown that presses driven by hydraulic cylinders or two screw hydraulic cylinder are the most optimal for technological operations as evidenced by references to domestic and foreign invention certificates and patents. The article presents disadvantages of forging on presses with hydraulic or pneumatic drive. It is a dependence of the deformation force, caused, mainly, by a force of the drive cylinder. The article gives linear movement rate quantities of press moving members depending on the drives of the actuating mechanism. Based on the above analysis of the features to manufacture work pieces on the knuckle joint presses, the article gives the rationale for the relevance of forging in a short period of time, provided that the moving parts of the press accumulate the required kinetic energy. This can be achieved only through modernization and improvement of forging

  10. Steve Jobs And Modern Leadership

    Directory of Open Access Journals (Sweden)

    Sorin-George Toma

    2013-05-01

    Full Text Available During the time, especially in the last fifty years, leadership has increasingly become a major subject in the management literature, a subject of much thought, writing and teaching. While the importance of leadership is generally accepted all over the world, there are as many definitions of it as there are organizations. In spite of the fact that the business literature on leadership is so voluminous, there is not an agreed-upon definition of the concept of leadership. Leadership is not only intensely studied, but also practiced in different organizations. How to lead effectively an organization depends on many factors such as the organizational culture, the behavior of the followers, and the personal traits of the leader. The vast majority of successful leaders are multi-dimensional individuals. The aims of our paper are to present a short biography of Steve Jobs and to highlight his contribution to modern leadership. Our research is based on a literature review. The S. Jobs example illustrates how a transformational leader as him can be a key factor in successfully turning round the fortunes of a company as Apple.

  11. Upgrade and modernization of NBSR

    International Nuclear Information System (INIS)

    Williams, Robert E.

    1995-01-01

    The NBSR, a 20-MW research reactor operated by the National Institute of Standards and Technology, has become the leading US laboratory in neutron research. About 1000 scientists from 200 industries, government and foreign laboratories, and universities conducted experiments at the NBSR in 19931. Since 1990, when the first instruments in the Cold Neutron Research Facility (CNRF) became available, the number of research participants has doubled. A major program of modernization and facility upgrade was initiated in order to meet this growing demand, and to assure safe and reliable reactor operations for 30 additional years. A scheduled shutdown, begun in late May 1994, is nearing completion at this writing (May 1995). To upgrade the CNRF, the D 2 0 cold neutron source has been replaced with a liquid hydrogen cold source, and the remaining four neutron guides are being installed. In addition, the primary and secondary cooling systems have been modernized with the installation of plate heat exchangers, and the refueling system has been completely refurbished. Periodic maintenance is also being done. The entire D20 primary coolant inventory is about to be replaced, and new shim arms have been installed

  12. Border mythology: Turner and modernity

    Full Text Available Modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. Modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. In this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc., for a reflection on the transformations of that civilized obsession called border. The border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. From the previous framework, we reflect on Turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the American frontier as ideological canon that explains and confirms the presence of the white race in a border re–made in the image and likeness of the “American Dream”. Frederick Turner’s reflection on the role of the frontier in American history is not only the study of the importance of progress towards the West but –even more so, is the analysis of meaning that had the American frontier as a historical process that ended in 1893, as Turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.

  13. Social Darwinism in modern China

    After evolutionary theory was introduced in China,Herbert Spencer's interpretation of it in the form of social Darwinism persuaded the Chinese that if they wanted to strengthen their nation,they would have to accept the brutal truth of natural selection,in which the principle of survival of the fittest rules.This version of evolutionary theory,when combined with the pragmatic thrust of Confucianism and the realpolitik of legalism from China's indigenous tradition,started a storm of materialism and utilitarianism in modern China.In the process,the traditional social order based on the rule of propriety (li) was completely subverted and replaced by a new order predicated on the rule of competition and power.This development produced a new mental outlook that privileged power over everything else,seriously undermined the rules of ethics and caused serious political consequences in the late Qing and early Republican period.This intellectual development may have contributed to ending the dynastic rule in China,but it was also responsible for ruining the newborn Republican China.The Chinese intellectuals of the May Fourth era critically reflected on this problematic legacy.While still believing in the notion of progress,they abandoned social Darwinism and embraced the idea of evolution through mutual assistance.Thus began a historical shift in modern China from focusing on wealth and power to focusing on civilization as China's salvation.

  14. GENDER FRONTIERS IN MODERN URBANISM

    2014-08-01

    Full Text Available On the basis of what perspectives are the city, the street, the home, the working place and the spaces for leisure being built? On the basis of whose interests and to what purposes are cities ordained? What ideology is behind this “order” proposed to the cities? This article presents a feminist critical analysis of urban modernism since its genesis on the XIX century, in the context of urbanization emerging from industrialization. For the most part, what has been produced on modern urbanism and its planning is male-white-European authored. Analysis, from a feminist perspective, leads to the questioning of “objective” knowledge, produced independently of positionality and thus to the adoption of standpoint epistemologies. Finally, going against the grain of mainstream urbanistic discourse, it demonstrates that the subject of knowledge is not neuter; urbanistic knowledge is produced by men, so as to tend to, and reinforce, patriarchal ideology. The consequences of such a situation are still felt by contemporary women.

    Talar osteochondral lesions are an important risk factor for the development of talar osteoarthritis. Furthermore, osteochondral lesions might explain persistent ankle pain. Early diagnosis of accompanying chondral defects is important to establish the optimal therapy strategy and thereby delaying or preventing the onset of osteoarthritis. The purpose of this review is to explain modern cartilage imaging with emphasis of MR imaging as well as the discussion of more sophisticated imaging studies like CT-arthrography or functional MR imaging. Pubmed literature search concerning: osteochondral lesions, cartilage damage, ankle joint, talus, 2 D MR imaging, 3 D MR imaging, cartilage MR imaging, CT-arthrography, cartilage repair, microfracture, OATS, MACT. Dedicated MR imaging protocols to delineate talar cartilage and the appearance of acute and chronic osteochondral lesions were discussed. Recent developments of MR imaging, such as isotropic 3 D imaging that has a higher signal-to noise ratio when compared to 2 D imaging, and specialized imaging methods such as CT-arthrography as well as functional MR imaging were introduced. Several classifications schemes and imaging findings of osteochondral lesions that influence the conservative or surgical therapy strategy were discussed. MRI enables after surgery the non-invasive assessment of the repair tissue and the success of implantation. Key points: Modern MRI allows for highly resolved visualization of the articular cartilage of the ankle joint and of subchondral pathologies. Recent advances in MRI include 3 D isotropic ankle joint imaging, which deliver higher signal-to-noise ratios of the cartilage and less partial volume artifacts when compared with standard 2 D sequences. In case of osteochondral lesions MRI is beneficial for assessing the stability of the osteochondral fragment and for this discontinuity of the cartilage layer is an important factor. CT-arthrography can be used in case of contraindications of MRI and

    Firsova, L.P.

    1977-01-01

    Modern ideas about kinetics of chemical reactions of hot atoms are generalized. The main points of the phenomenological theories (''kinetic theory'' of Wolfgang-Estrup hot reactions and the theory of ''reactions integral probability'' of Porter) are given. Physico-chemical models of elastic and non-elastic collisions are considered which are used in solving Boltzmann integro-differential equations and stochastic equations in the Porter theory. The principal formulas are given describing probabilities or yields of chemical reactions, initiated with hot atoms, depending on the distribution functions of hot particles with respect to energy. Briefly described are the techniques and the results of applying the phenomenological theories for interpretation of the experimental data obtained during nuclear reactions with hot atoms, photochemical investigations, etc. 96 references are given

    Kinetics of thyroid hormones were outlined, and recent progress in metabolism of these hormones was also described. Recently, not only T 4 and T 3 but also rT 3 , 3,3'-T 2 , 3',5'-T 2 , and 3,5-T 2 can be measured by RIA. To clarify metabolic pathways of these hormones, metabolic clearance rate and production rate of these hormones were calculated. As single-compartment analysis was insufficient to clarify disappearance curves of thyroid hormones in blood such as T 3 and T 2 of which metabolic speed was so fast, multi-compartment analysis or non-compartment analysis were also performed. Thyroid hormones seemed to be measured more precisely by constant infusion method. At the first step of T 4 metabolism, T 3 was formed by 5'-monodeiodination of T 4 , and rT 3 was formed by 5-monodeiodination of T 4 . As metabolic pathways of T 3 and rT 3 , conversion of them to 3,3'-T 2 or to 3',5'-T 2 and 3,5-T 2 was supposed. This subject will be an interesting research theme in future. (Tsunoda, M.)

  20. How does Modernity Taste? Tomatoes in the Societal Change from Modernity to Late Modernity

    Directory of Open Access Journals (Sweden)

    Lena Ekelund

    2011-10-01

    Full Text Available The aim of this article is to discuss how changes in tomato food regulation, production and consumption, can be seen as part of a broader societal change from Modernity to Late Modernity. Based on evidence from the Swedish and European food systems we demonstrate how a system, which has been successfully managing development in food production for several decades by stressing rationality, homogeneity and standardization, is being challenged by a system that has adapted to, and also exploited, consumer preferences such as heterogeneity, diversity and authenticity. The article shows how tomato growers develop differentiation strategies, adapting to and cultivating this new consumer interest, and how authorities responsible for regulations of trade and quality struggle to adapt to the new situation. As the products become more diversified, taste becomes an important issue and is associated with a view that traditional and natural are superior to standardized and homogeneous products. The analytical approaches for the discussion come from two study areas: ethnological, and marketing and policy perspective, thus showing a multidimensional picture of a changing food system.

    This article will examine how the contemporary development of sustainable buildings has been influenced by the concept of ecological modernisation. Ecological modernisation is a policy concept describing how environmental considerations are increasingly being integrated into modern society...... driven by enthusiasts and grassroots to being a more widespread, generally obtainable and integrated product. We will discuss to what degree this can be understood within the ideas of ecological modernisation, and then discuss the benefits and drawbacks of this development. Based on the concepts...... of governance, standardisation and visibility, the conclusion is that in many ways ecological modernisation has penetrated in Danish sustainable buildings and has contributed to a positive development. However, there are aspects of sustainable consumption that this development does not relate to, including...

    Compulsive gambling has received widespread attention in the last decade. Gambling has become the first non-chemical addiction, which went down to the section "Addiction and related disorders" of the modern DSM-V. The review considers non-pharmacological and pharmacological approaches to the treatment of gambling. Among non-drug approaches, cognitive-behavioral therapy and 12-step programs have gained the most popularity in the "Gamblers Anonymous" community. Among pharmacological approaches, three classes of drugs: antidepressants (mainly SSRIs), opiate antagonists (naltrexone and nalmefene) and mood stabilizers (valproate, lithium, topiramate) proved to be effective in treatment of gambling. No differences in the efficacy of the three classes of psychotropic drugs have been identified. Preliminary results for N-acetylcysteine and memantine cause optimism in terms of perspective.

  4. Modern canonical quantum general relativity

    CERN Document Server

    Thiemann, Thomas

    2007-01-01

    This is an introduction to the by now fifteen years old research field of canonical quantum general relativity, sometimes called "loop quantum gravity". The term "modern" in the title refers to the fact that the quantum theory is based on formulating classical general relativity as a theory of connections rather than metrics as compared to in original version due to Arnowitt, Deser and Misner. Canonical quantum general relativity is an attempt to define a mathematically rigorous, non-perturbative, background independent theory of Lorentzian quantum gravity in four spacetime dimensions in the continuum. The approach is minimal in that one simply analyzes the logical consequences of combining the principles of general relativity with the principles of quantum mechanics. The requirement to preserve background independence has lead to new, fascinating mathematical structures which one does not see in perturbative approaches, e.g. a fundamental discreteness of spacetime seems to be a prediction of the theory provi...

    2016-01-01

    We have recently demonstrated a very favorable, inexpensive modernization of lab- based x-ray absorption fine structure (XAFS) and high-resolution x-ray emission spectroscopy (XES) using only commercially-available optics and x-ray tube sources. Here, we survey several proven instrument designs that can be readily implemented in any laboratory setting to achieve synchrotron-quality XAFS and XES for many systems in the 5 keV to 10 keV energy range. These approaches are based on our immediate experience with the development of: (1) an inexpensive, low-powered monochromator capable of performing either XAFS or XES, (2) a mid-scale XAFS user facility having 10 6 /sec flux with sub-eV bandwidth on each of two independent beamlines, and (3) multiple XES spectrometers having outstanding performance that can complement synchrotron XAFS studies in battery and actinide research.

    Goodwin, R.W.; Shea, M.F.

    1984-05-01

    Beginning in the mid to late sixties, most new accelerators were designed to include computer based control systems. Although each installation differed in detail, the technology of the sixties and early to mid seventies dictated an architecture that was essentially the same for the control systems of that era. A mini-computer was connected to the hardware and to a console. Two developments have changed the architecture of modern systems: (a) the microprocessor and (b) local area networks. This paper discusses these two developments and demonstrates their impact on control system design and implementation by way of describing a possible architecture for any size of accelerator. Both hardware and software aspects are included

    Full Text Available Bushido is most often translated as the way of the warrior caste in Japan. Bushirefers to warriors in feudal Japan while do means several things including: the correct way,the path, or the road. Another interpretation of Bushido could be the way of preserving peacethrough the use of force. Bushido comes out of Buddhism, Confucianism, and Shintoism. Thecombination of these schools of thought and religions has formed the code of warrior valuesknown as Bushido. A key to our understanding of how the concepts of Bushido fit into Japanesemodern lives is to understand the historical and societal aspects of Bushido. Today, this meaningcan be modernized to include minimizing violent conflict. The code of Bushido, the Samurai'scode of honor, upholds loyalty, discipline, total dedication, honor and valor, and numerousexamples of these elements can be witnessed today or in recent history.

    Full Text Available In the European states, a responsible administration, from a political point of view,coordinated by law, competent and professional and neutral from a public point of view, has been thebasis for the European state for a long time and a dominant model of this type of administration isrepresented by the Weberian bureaucratic model, which emphasized the value of efficiency, consistency,continuity and predictability. Bureaucracy is indispensable in any state and very important in thedemocratic regimes. Weber asserted that the bureaucratic organisation obtained power in virtue of thedecrease of the economical and social differences. The modern state depends on a bureaucratic basis,but once established, bureaucracy is among the social structures that are most difficult to eliminate. Theemergence and development of the bureaucratic mechanisms has become a monster of the modernsociety, because the bureaucracy works in the opposite direction from democracy.

    2014-09-01

    Full Text Available Communicating parties inside computer networks use different kind of identifiers. Some of these identifiers are stable, e.g., logins used to access a specific service, some are only temporary, e.g., dynamically assigned IP addresses. This paper tackles several challenges of lawful interception that emerged in modern networks. The main contribution is the graph model that links identities learnt from various sources distributed in a network. The inferred identities result into an interception of more detailed data in conformance with the issued court order. The approach deals with network address translation, short-lived identifiers and simultaneous usage of different identities. The approach was evaluated to be viable during real network testing based on various means to learn identities of users connected to a network.

  12. Rational reconstructions of modern physics

    CERN Document Server

    Mittelstaedt, Peter

    2013-01-01

    Newton’s classical physics and its underlying ontology are loaded with several metaphysical hypotheses that cannot be justified by rational reasoning nor by experimental evidence. Furthermore, it is well known that some of these hypotheses are not contained in the great theories of Modern Physics, such as the theory of Special Relativity and Quantum Mechanics. This book shows that, on the basis of Newton’s classical physics and by rational reconstruction, the theory of Special Relativity as well as Quantum Mechanics can be obtained by partly eliminating or attenuating the metaphysical hypotheses. Moreover, it is shown that these reconstructions do not require additional hypotheses or new experimental results. In the second edition the rational reconstructions are completed with respect to General Relativity and Cosmology. In addition, the statistics of quantum objects is elaborated in more detail with respect to the rational reconstruction of quantum mechanics. The new material completes the approach of t...

    2015-05-01

    Full Text Available This article explores dynamics behind the emergence of different nationalistic currents that dominated the modern Syrian political scene. By “modern”, here, it is meant the period between 1846, when the term “Syria” was, for the first time, officially associated with a specific territory, and 2000 when Syria’s “fierce”, not strong, ruler Hafez al-Asad died. As such, the article covers multiple periods as one continuous period. Arab Nationalism, which defeated other currents like Pan Syrianism and Communism, comes on the top of these currents. The article also shows how partisan, clan and/or family interests led to the utilization of various nationalist thoughts in this regard.

    Full Text Available The subject of the article is a studying of modern ideologies of managing fear. The purpose of the article is to examine the managing fear practice and explain how it is used in the policy of homeland security. The research methodology is based on the general scientific methods such as analysis and synthesis, induction and deduction and special kind of theoretical me-thods such as studying literature about the problem. The study can be used in courses on social philosophy and political science. The author concludes that social fears are very effective instrument of influence with mass consciousness. The authorities need to legitimize their political decisions through public opinion. But before that they should form it. The author shows how policy of homeland security helps to produce fears in society and how politicians intentionally exaggerate them. In this regard the author considers a concept of homeland security which can eliminate the negative sides of homeland security in future.

  20. Modernism and catholic political doctrine

    Directory of Open Access Journals (Sweden)

    Henry T. Sardaryan

    2017-01-01

    Full Text Available The article studies the perception of Modernism by the Catholic Church as a movement within the clerical structure and philosophy that existed during the 19-20th centuries in the framework of general skepticism and rejection of tradition, prioritization of individualism, formal equality, faith in inevitability of social, scientific and technological progress, rationalization and professionalization. A distinctive feature of this movement is the participation of the priests themselves, especially in France and Italy. The object of research is the Catholic political doctrine during the pontificate of Pius X. Modernist movement in Catholicism, in opinion of many scientists had a decisive impact on the reform direction during the Second Vatican Council, but on closer study of the discourse that took place in the late 19th - early 20th centuries, it becomes obvious that this is not true. The focus of the article is the political doctrine of Catholicism - the issue of state political structure, its relationship with church institutions, status of the individual in societyc. In this regard, the modernists gave priority to necessity of secularization and complete separation of secular and spiritual power. In the article different scientifical methods, ave used such as dialectical, logical, comparative, systematic. The main conclusion of the author is that modernism should be regarded as an unsuccessful attempt to reform the Catholic Church that could have lead to its another schism, rather than a route towards the Second Vatican Council. The desire to change the structure, methods of church mission, its hierarchy and a number of other formal elements – was implemented by church itself for multiple times before. However, revision of the foundations of Christian ethics and its ontology, including its political doctrine, ran into resistance of the Holy See, causing, in essence, a rhetorical question - whether scientific and technical progress should

    In modern intensive agriculture, plastics are used in several applications (i.e. mulch films, drip irrigation tubes, string, clips, pots, etc.). Interest towards applying biodegradable plastics to replace the conventional plastics is promising. Ten monomers, which can be applied in the synthesis of potentially biodegradable polyesters, were tested according to ASTM 5988-96 (standard respirometric test to evaluate aerobic biodegradation in soil by measuring the carbon dioxide evolution): adipic acid, azelaic acid, 1,4-butanediol, 1,2-ethanediol, 1,6-hexanediol, lactic acid, glucose, sebacic acid, succinic acid and terephthalic acid. Eight replicates were carried out for each monomer for 27-45 days. The numerical code AQUASIM was applied to process the CO₂ experimental data in order to estimate values for the parameters describing the different mechanisms occurring to the monomers in soil: i) the first order solubilization kinetic constant, K(sol) (d⁻¹); ii) the first order biodegradation kinetic constant, K(b) (d⁻¹); iii) the lag time in biodegradation, t(lag) (d); and iv) the carbon fraction biodegraded but not transformed into CO₂, Y (-). The following range of values were obtained: [0.006 d⁻¹, 6.9 d⁻¹] for K(sol), [0.1 d⁻¹, 1.2 d⁻¹] for K(b), and [0.32-0.58] for Y; t(lag) was observed for azelaic acid, 1,2-ethanediol, and terephthalic acid, with estimated values between 3.0 e 4.9 d.

    Full Text Available According to the last book of Peter V. Zima Modern/Postmodern (2010 modernism/modernity, postmodernism/postmodernity is once again a subject of reflection in contemporary aesthetics. It attempts to examine those concept not only in artistic, stylistic way, but also from the other points of view: historical, political, social, ideological. I would like to reveal a thesis that a distance of last decade or two we recognise that we are more and more from the spirit of postmodernism/postmodernity and that we open some problem once again that modernity had in the centre of its reflection: identity of subject, sense of existence, the feeling of crisis: the art of crisis. Does it mean a return of some points of modernism/modernity? I will try to answer to this questions by inviting to a discussion also other contemporary thinkers (Jean-Luc Nancy, Alain Badiou, and Jacques Rancière.

    2013-01-01

    Full Text Available The process of modern design under the distributed resource environment is interpreted as the process of knowledge flow and integration. As the acquisition of new knowledge strongly depends on resources, knowledge flow can be influenced by technical, economic, and social relation factors, and so forth. In order to achieve greater efficiency of knowledge flow and make the product more competitive, the root causes of the above factors should be acquired first. In this paper, the authors attempt to reveal the nature of design knowledge flow from the perspectives of fluid dynamics and energy. The knowledge field effect and knowledge agglomeration effect are analyzed, respectively, in which the knowledge field effect model considering single task node and the single knowledge energy model in the knowledge flow are established, then the general expression of knowledge energy conservation with consideration of the kinetic energy and potential energy of knowledge is built. Then, the knowledge flow rules and their influential factors including complete transfer and incomplete transfer of design knowledge are studied. Finally, the coupling knowledge flows in the knowledge service platform for modern design are analyzed to certify the feasibility of the research work.

    1993-01-01

    High performance polymeric materials are finding increased use in aerospace applications. Proposed high speed aircraft will require materials to withstand high temperatures in an oxidative atmosphere for long periods of time. It is essential that accurate estimates be made of the performance of these materials at the given conditions of temperature and time. Temperatures of 350 F (177 C) and times of 60,000 to 100,000 hours are anticipated. In order to survey a large number of high performance polymeric materials on a reasonable time scale, some form of accelerated testing must be performed. A knowledge of the rate of a process can be used to predict the lifetime of that process. Thermogravimetric analysis (TGA) has frequently been used to determine kinetic information for degradation reactions in polymeric materials. Flynn and Wall studied a number of methods for using TGA experiments to determine kinetic information in polymer reactions. Kinetic parameters, such as the apparent activation energy and the frequency factor, can be determined in such experiments. Recently, researchers at the McDonnell Douglas Research Laboratory suggested that a graph of the logarithm of the frequency factor against the apparent activation energy can be used to predict long-term thermo-oxidative stability for polymeric materials. Such a graph has been called a kinetic map. In this study, thermogravimetric analyses were performed in air to study the thermo-oxidative degradation of several high performance polymers and to plot their kinetic parameters on a kinetic map.

  14. Phenomenology of modern education quality

    2017-01-01

    Full Text Available The national priority question of education quality is considered in the article at the level of an in-depth – existential – function of the educational system, where the former arises. In that case, education appears not only as a social organism, but a fundamental form of understanding existence and self-realization of a person as a self-organized space and biosocial system in terms of an integral educational result. The mechanisms and effects of formal development logic become clear from such research perspective namely, that changes into philosophy of education in the shape of a single-dimensional methodological imperative and provides for an inconsistency of educational practice, achievement of some pedagogical aims at the expense and to the disadvantage of others. The limited nature of pedagogical thinking is not simply fixed in the paradoxes of human development as an individual and organism, but is considered as the main obstacle in the way of evolution of the Human-Nature-Society global system. The phenomenological comprehension of education problems supposes coming into the space of a spiritual idea, funding the process of searching for quality at different levels of human life and activities from within, which characterizes the topicality of the given article. The aim of the scientific research is to analyze factors limiting the process of modern human development, and to ground the necessity of the fundamental updating of the education model in the noospheric scientific paradigm. Theoretical methods of research are used in the paper: analysis of scientific literature, system analysis, analogy, systematization, and generalization. The research results are represented in the categories of education philosophy and focus the reader’s attention mainly on its critical-reflexive function. Elimination of the subject of education is considered as a logical result of phenomenological reduction of thinking that loses a higher level of

  15. Research reactor modernization and refurbishment

    International Nuclear Information System (INIS)

    2009-08-01

    Many recent, high profile research reactor unplanned shutdowns can be directly linked to different challenges which have evolved over time. The concept of ageing management is certainly nothing new to nuclear facilities, however, these events are highlighting the direct impact unplanned shutdowns at research reactors have on various stakeholders who depend on research reactor goods and services. Provided the demand for these goods and services remains strong, large capital projects are anticipated to continue in order to sustain future operation of many research reactors. It is within this context that the IAEA organized a Technical Workshop to launch a broader Agency activity on research reactor modernization and refurbishment (M and R). The workshop was hosted by the operating organization of the HOR Research Reactor in Delft, the Netherlands, in October 2006. Forty participants from twenty-three countries participated in the meeting: with representation from Africa, Asia Pacific, Eastern Europe, North America, South America and Western Europe. The specific objectives of this workshop were to present facility reports on completed, existing and planned M and R projects, including the project objectives, scope and main characteristics; and to specifically report on: - the project impact (planned or actual) on the primary and key supporting motivation for the M and R project; - the project impact (planned or actual) on the design basis, safety, and/or regulatory-related reports; - the project impact (planned or actual) on facility utilization; - significant lessons learned during or following the completion of M and R work. Contributions from this workshop were reviewed by experts during a consultancy meeting held in Vienna in December 2007. The experts selected final contributions for inclusion in this report. Requests were also distributed to some authors for additional detail as well as new authors for known projects not submitted during the initial 2006 workshop

Pour ce qu’elle vaut, l’industrie vinicole sert également l’intérêt de l’État-parti en renforçant sa légitimité et en établissant son agenda politique. Dans cet article, qui rend compte de l’histoire du vin chinois ainsi que sa situation actuelle, la boisson est prise comme exemple des changements culinaires contemporains, mais surtout comme moyen d’explorer les significations et les limites sociales d’une modernité émergente distinctement chinoise. Une modernité qui dans sa volonté apparente d’absorber le nouveau et l’étranger remplace la dichotomie sino-occidentale jusque là prédominante, tout en adhérant toujours aux vieilles rengaines ‘que l’ancien serve le présent’ et ‘que l’étranger serve le chinois.’As grape wine tries to sell its way into the standard culinary repertoire of China, it is more than simply a process of a global culinary flow from the centre to the periphery. Chinese wine has become a new tool for identification as well as a sign of the nation’s renegotiated position in the world. For what it is worth, the wine industry also serves the interest of the party-state by strengthening its legitimacy and substantiating its political agenda. In this article, which reviews China’s wine history as well as the present situation, the drink is taken as an example of contemporary culinary change, but foremost as a means to explore the meanings and social limits of an emergent distinctly Chinese modernity. A modernity that in its apparent willingness to embrace the new and foreign supersedes the hitherto predominant Sino-Western dichotomy, while still adhering to the

  17. Gyrocenter-gauge kinetic theory

    Qin, H.; Tang, W.M.; Lee, W.W.

    2000-01-01

    Gyrocenter-gauge kinetic theory is developed as an extension of the existing gyrokinetic theories. In essence, the formalism introduced here is a kinetic description of magnetized plasmas in the gyrocenter coordinates which is fully equivalent to the Vlasov-Maxwell system in the particle coordinates. In particular, provided the gyroradius is smaller than the scale-length of the magnetic field, it can treat high frequency range as well as the usual low frequency range normally associated with gyrokinetic approaches. A significant advantage of this formalism is that it enables the direct particle-in-cell simulations of compressional Alfven waves for MHD applications and of RF waves relevant to plasma heating in space and laboratory plasmas. The gyrocenter-gauge kinetic susceptibility for arbitrary wavelength and arbitrary frequency electromagnetic perturbations in a homogeneous magnetized plasma is shown to recover exactly the classical result obtained by integrating the Vlasov-Maxwell system in the particle coordinates. This demonstrates that all the waves supported by the Vlasov-Maxwell system can be studied using the gyrocenter-gauge kinetic model in the gyrocenter coordinates. This theoretical approach is so named to distinguish it from the existing gyrokinetic theory, which has been successfully developed and applied to many important low-frequency and long parallel wavelength problems, where the conventional meaning of gyrokinetic has been standardized. Besides the usual gyrokinetic distribution function, the gyrocenter-gauge kinetic theory emphasizes as well the gyrocenter-gauge distribution function, which sometimes contains all the physics of the problems being studied, and whose importance has not been realized previously. The gyrocenter-gauge distribution function enters Maxwell's equations through the pull-back transformation of the gyrocenter transformation, which depends on the perturbed fields. The efficacy of the gyrocenter-gauge kinetic approach is

    In this paper, we provide a simple and modern discussion of rotational superradiance based on quantum field theory. We work with an effective theory valid at scales much larger than the size of the spinning object responsible for superradiance. Within this framework, the probability of absorption by an object at rest completely determines the superradiant amplification rate when that same object is spinning. We first discuss in detail superradiant scattering of spin 0 particles with orbital angular momentum ℓ=1, and then extend our analysis to higher values of orbital angular momentum and spin. Along the way, we provide a simple derivation of vacuum friction — a “quantum torque” acting on spinning objects in empty space. Our results apply not only to black holes but to arbitrary spinning objects. We also discuss superradiant instability due to formation of bound states and, as an illustration, we calculate the instability rate Γ for bound states with massive spin 1 particles. For a black hole with mass M and angular velocity Ω, we find Γ∼(GMμ){sup 7}Ω when the particle’s Compton wavelength 1/μ is much greater than the size GM of the spinning object. This rate is parametrically much larger than the instability rate for spin 0 particles, which scales like (GMμ){sup 9}Ω. This enhanced instability rate can be used to constrain the existence of ultralight particles beyond the Standard Model.

  20. OBESITY : A MODERN DAY PLAGUE.

    Obesity is the presence of excess body fat. Unfortunately obesity is taken as a mere cosmetic problem and not a medical one. Today obesity is being 'dealt' with more by the self-proclaimed fitness experts running the rapidly mushrooming fitness centres rather than by medical professionals. But rather than merely a cosmetic problem, obesity should be viewed as a disease because there are multiple biologic hazards at surprisingly low levels of excess fat With the rapid pace of industrialisation and economic progress, today more and more jobs are becoming sedentary and dietary patterns are also changing with a decline in the cereal intake and increase in the intake of sugar and fats. However, inherited physiologic differences in response to eating and exercise are also important factors. Treating obesity can often be a frustrating experience for both the physician and the patient because of the great difficulty in maintaining weight loss over the long term. However, a clear understanding of the causes of obesity and a treatment strategy based on a combination of diet, nutrition, education, exercise, behaviour modification and social support can go a long way in containing this 'modern day plague' before it acquires epidemic proportions.

  1. Modern Clinical Research on LSD.

    2017-10-01

    All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT 2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility. LSD impaired the recognition of sad and fearful faces, reduced left amygdala reactivity to fearful faces, and enhanced emotional empathy. LSD increased the emotional response to music and the meaning of music. LSD acutely produced deficits in sensorimotor gating, similar to observations in schizophrenia. LSD had weak autonomic stimulant effects and elevated plasma cortisol, prolactin, and oxytocin levels. Resting-state functional magnetic resonance studies showed that LSD acutely reduced the integrity of functional brain networks and increased connectivity between networks that normally are more dissociated. LSD increased functional thalamocortical connectivity and functional connectivity of the primary visual cortex with other brain areas. The latter effect was correlated with subjective hallucinations. LSD acutely induced global increases in brain entropy that were associated with greater trait openness 14 days later. In patients with anxiety associated with life-threatening disease, anxiety was reduced for 2 months after two doses of LSD. In medical settings, no complications of LSD administration were observed. These data should contribute to further investigations of the therapeutic potential of LSD in psychiatry.

    Full Text Available The Sicilian writer and playwright Luigi Pirandello lived between two worlds: the late Sic­ily universe in the end of the nineteenth century, and the bold modernity in the beginning of the twentieth century. His work encompasses the changes in the system of values as well as the social and historical transformations. At the same time, he highlights the powerless man who was facing such reality and this becomes a meaningful element in his texts. Pirandello’s poetic constitutes itself according to the dynamics and theme of a criticizing decadence towards society, the postulates of an artistic radicalism and the absence of history, and life meaning as well. O falecido Mattia Pascal, Um, nenhum e cem mil, Assim é (se lhe parece e Seis Personagens à Procura de um Autor are the works cited in this paper with the purpose of showing that fragmentation, mimesis disruption and anti-representation are constant in Pirandello’s works which are immersed in the contradictory mo­dernity.

  3. Modern rotor balancing - Emerging technologies

    Science.gov (United States)

    Zorzi, E. S.; Von Pragenau, G. L.

    1985-01-01

    Modern balancing methods for flexible and rigid rotors are explored. Rigid rotor balancing is performed at several hundred rpm, well below the first bending mode of the shaft. High speed balancing is necessary when the nominal rotational speed is higher than the first bending mode. Both methods introduce weights which will produce rotor responses at given speeds that will be exactly out of phase with the responses of an unbalanced rotor. Modal balancing seeks to add weights which will leave other rotor modes unaffected. Also, influence coefficients can be determined by trial and error addition of weights and recording of their effects on vibration at speeds of interest. The latter method is useful for balancing rotors at other than critical speeds and for performing unified balancing beginning with the first critical speed. Finally, low-speed flexible balancing permits low-speed tests and adjustments of rotor assemblies which will not be accessible when operating in their high-speed functional configuration. The method was developed for the high pressure liquid oxygen turbopumps for the Shuttle.

  4. Casebooks in Early Modern England:

    Science.gov (United States)

    Kassell, Lauren

    2014-01-01

    summary Casebooks are the richest sources that we have for encounters between early modern medical practitioners and their patients. This article compares astrological and medical records across two centuries, focused on England, and charts developments in the ways in which practitioners kept records and reflected on their practices. Astrologers had a long history of working from particular moments, stellar configurations, and events to general rules. These practices required systematic notation. Physicians increasingly modeled themselves on Hippocrates, recording details of cases as the basis for reasoned expositions of the histories of disease. Medical records, as other scholars have demonstrated, shaped the production of medical knowledge. Instead, this article focuses on the nature of casebooks as artifacts of the medical encounter. It establishes that casebooks were serial records of practice, akin to diaries, testimonials, and registers; identifies extant English casebooks and the practices that led to their production and preservation; and concludes that the processes of writing, ordering, and preserving medical records are as important for understanding the medical encounter as the records themselves.

    With an objective of saving energy and reducing greenhouse gas emission, investigations and discussions were given on a modernization project for Byuzmeyinsky Cement Factory, the only cement factory in Turkmenistan. Byuzmeyinsky Cement Factory uses the wet process which consumes a large amount of energy, is inferior in production efficiency and quality, and discharging a great amount of greenhouse effect gas. The present project will execute change of the raw material crusher into a vertical roll mill for one of the four wet kilns, and change of the facilities for raw material powder mixing and storing and clinker manufacturing into dry-type facilities using the NSP system. As a result of the discussions, the energy saving effect would be 86,321 tons of crude oil equivalent annually, and the greenhouse gas emission reducing effect would be 224,467 t-CO2 annually. The total fund amount required for the project is estimated to be 90,211,000 dollars. With regard to the profitability, the internal financial profit rate would be 9.71% after tax, and the ROE would be 18.62%, whereas the project is considered feasible. (NEDO)

    Full Text Available The article is focused on the spatial structure of modern Moscow and features distinguishing it from the cities of Western Europe and the US. The city has hybrid spatial structure combining elements which emerged on different stages of the city development. In the 14th century two tendencies appeared: the prestige of the city centre and opposition of Western districts as more prestigious to Eastern districts as less prestigious. Crucial spatial characteristics emerged in the Soviet era and up to now they define the image of Moscow. Firstly, it's a peculiar density profile. Population density in post-socialist cities tends to increase as we move further from the city centre while in Western European cities population density is the highest in central districts. Secondly, elementary units of Moscow spatial structure are so called micro-districts (neighbourhoods. The concept of a microdistrict was very popular with Soviet urban planners and widely applied in the residential construction. Another peculiarity of Moscow spatial structure is social heterogeneity of districts and absence of ethnic quarters or ghettos. Furthermore, significant part of the city area is occupied by former industrials zones which are not used anymore and need to be reconstructed. With transition to market economy a number of spatial changes emerged. They were partly related to the large-scale privatization, infill construction and lack of effective urban planning policy. In conclusion the article states the need for the new model of spatial organization which would take into account the specifics of Russian reality.

    The main content of the innovation processes is making changes to traditional, established systems and progressive experience which became widespread. Virtualization of processes in education goes beyond the innovation process, as it is treated in the literature on education. In modern pedagogical science it is an introduction of the new to objectives, contents, methods and forms of training and education, the organization of joint activity of the teacher and the student. It is a progressive start in the development of a university. It is the use of information technology, including virtual learning tools associated with the decision of cardinal issues in the methodology of science in general, and in the philosophy of education in particular. And here postmodernism manifests itself with a particular force. Its credo – the approval of conditional, never to the end identified specific contextual nature of any discourse. Not by accident that the works of researchers note that the advent of the Internet is due to the spread of the values of postmodernism, its philosophical and ideological and anthropological specificity.

    Full Text Available The car industry uses a tremendous number of materials to build cars, including iron, aluminum, steel, glass, rubber, petroleum products, copper, steel and others. These materials have evolved greatly over the decades, becoming more sophisticated, better built, and safer. They've changed as new automotive manufacturing technologies have emerged over the years, and they're used in increasingly innovative ways. This article is devoted to systematization information on the introduction and application of modern materials in the automotive industry. Given both domestic and foreign sources of information, it follows that car manufacturers are constantly pushing to create the lightest cars possible to increase speed and power. Research and development into lightweight materials is essential for lowering their cost, increasing their ability to be recycled, enabling their integration into vehicles, and maximizing their fuel economy benefits. Light weighting without loss of strength and speed properties is the present, and the future, of the automotive manufacturing industry. It brings innovative materials to the frontline of design.

  10. Scientific knowledge and modern prospecting

    Science.gov (United States)

    Neuerburg, G.J.

    1985-01-01

    Modern prospecting is the systematic search for specified and generally ill-exposed components of the Earth's crust known as ore. This prospecting depends entirely on reliable, or scientific knowledge for guidance and for recognition of the search objects. Improvement in prospecting results from additions and refinements to scientific knowledge. Scientific knowledge is an ordered distillation of observations too numerous and too complex in themselves for easy understanding and for effective management. The ordering of these observations is accomplished by an evolutionary hierarchy of abstractions. These abstractions employ simplified descriptions consisting of characterization by selected properties, sampling to represent much larger parts of a phenomenon, generalized mappings of patterns of geometrical and numerical relations among properties, and explanation (theory) of these patterns as functional relations among the selected properties. Each abstraction is predicated on the mode of abstraction anticipated for the next higher level, so that research is a deductive process in which the highest level, theory, is indispensible for the growth and refinement of scientific knowledge, and therefore of prospecting methodology. ?? 1985 Springer-Verlag.

Carbon and kevlar filaments are the most prospective ones. For the service at medium, high or superhigh temperatures selection of matrix material is more significant than selection of filament. Organic matrices can not be used at temperatures > 250 deg C: this is already the range of metal matrix application. Though at temperatures above room one many filaments can be used, boron filaments and metal wire are the only reinforcing materials, inspite of the fact that carbon filaments are successfully used for metal matrix reinforcing. At very high temperatures only carbon filaments or silicon carbide ones can be used, but their cost is very high and besides economical problems there are many difficulties of technical character

  14. Calculation of Kinetic Parameters of TRIGA Reactor

    International Nuclear Information System (INIS)

    Snoj, Luka; Kavcic, Andrej; Zerovnik, Gasper; Ravnik, Matjaz

    2008-01-01

    Modern Monte Carlo transport codes in combination of fast computer clusters enable very accurate calculations of the most important reactor kinetic parameters. Such are the effective delayed neutron fraction, β eff , and mean neutron generation time, Λ. We calculated the β eff and Λ for various realistic and hypothetical annular TRIGA Mark II cores with different types and amount of fuel. It can be observed that the effective delayed neutron fraction strongly depends on the number of fuel elements in the core or on the core size. E.g., for 12 wt. % uranium standard fuel with 20 % enrichment, β eff varies from 0.0080 for a small core (43 fuel rods) to 0.0075 for a full core (90 fuel rods). It is interesting to note that calculated value of β eff strongly depends also on the delayed neutron nuclear data set used in calculations. The prompt neutron life-time mainly depends on the amount (due to either content or enrichment) of 235 U in the fuel as it is approximately inversely proportional to the average absorption cross-section of the fuel. E.g., it varies from 28 μs for 30 wt. % uranium content fuelled core to 48 μs for 8.5 wt. % uranium content LEU fuelled core. The results are especially important for pulse mode operation and analysis of the pulses. (authors)

  15. Kinetics of strength gain of biocidal cements

    Directory of Open Access Journals (Sweden)

    Rodin Aleksandr Ivanovich

    Full Text Available Biocorrosion becomes the determinative durability factor of buildings and constructions. Damages of construction materials caused by bacteria, filamentous fungi, actinomycetes constitute a serious danger to the constructions of a building or a structure and to the health of people. Biodeteriorations are typical both in old and new constructions. A great quantity of destruction factors of industrial and residential buildings under the influence of microorganisms was established in practice. Providing products and constructions based on concretes fungicidal and bactericidal properties is an important direction of modern construction material science. The most efficient way to solve this task is creation of biocidal cements. The article presents the results of experimental studies of kinetic dependences of strength gain by biocidal cements by physico-mechanical and physico-chemical analysis methods. The identical velocity character of initial hydration of the developed compositions of biocidal cements is set, as well as a more calm behavior of hardening processes at later terms. It has been established that the compositions of biocidal cements modified by sodium sulfate and sodium fluoride possess the greatest strength.

  15. From Hippocrates to modern medicine.

    Science.gov (United States)

    Orfanos, C E

    2007-07-01

    Hippocrates was the first to introduce the concept of 'physis' and to transform hieratic or theocratic medicine into rational medicine. The overall construction of the Asclepieion on Kos clearly indicates that he and his school followed a holistic concept, combining scientific thought with drug therapy, diet schedules, and physical and mental exercise, also asking for God's help. Hippocrates also formulated the first standards and ethical rules to be followed in medical profession, which are still valid today. The knowledge of Graeco-Roman medicine has been transferred by Arab scholars into the West, whereas renaissance, urbanization, and industrialisation have changed its face over the centuries. With the entrance of molecular technology and economy, modern medicine now faces the risk of becoming itself industrialized. Correct use of new scientific knowledge, individualized management with a Hippocratic holistic approach and compassionate sympathy for the patient who suffers, should be considered in the years to come for maintaining the level of medical profession. The venue of our European Congress in Rhodes is very close to Kos, another historic Aegean island, the place where Hippocrates has given the first professional standards in European medicine and in medicine in general. They were established 2600 years ago and are still valid today.(1,2) If one draws a red line and marks some cornerstones of the evolution that has taken place in medicine over the past centuries, it is evident that these first rules formulated by Hippocrates and his school also reveal the future responsibilities for our profession and make them better recognizable and more conclusive.

    2003-01-01

    It is a general rule today, after a relevant diagnostics of an epilepsy, to start a monotherapy treatment, depending on a kind of a seizure, a life age and a general health condition. First line of monotherapy epilepsy drugs remain carbamazapine and sodium valproat. New drugs that are being introduced are: felbamat, gabapentin, lamotrigin, oxcarbazepin, tiagabin, topiramat, vigabatin and zanisamid. These are commonly used as add-on therapy, or as an addition for previously used antiepileptic. Their indicated areas are complex resistant partial seizures with or without generalization. Attention should be paid on proper dosage, interactions and toxicity. Regardless on the new epileptic era, according to reports of International League against epilepsy, most of the patients do not receive the drug that is the most appropriate for them concerning the price (cost-benefit). Neurosurgical methods in epilepsy treatment are: selective amygdalo-hyppocampotomy, temporal lobotomy, subpial resection, hemispherectomy, corpus callosotomy, removal of lesions like tumors or cysts provide encouraging results in reduction of epileptic seizures that can be followed by reduction of drug therapy. N. vagus stimulation is being wider introduced in resident epileptics. Treatment of epilepsy in women requires an approach to sexuality, conception, pregnancy, introduction of medicaments, antiepileptic terratogenity, contraception, motherhood and menopause. A special significance of modern approach to epilepsy is in treatment of elderly who have cerebrovascular and neurodegenerative disease as a cause of seizures. A complex treatment of epilepsy using pharmacological and neurosurgical approach requires supportive psychotherapy, socio-therapy, the work with a family, education about epilepsy and living a life with more quality having one.

  18. Transformation kinetics for nucleus clusters

    International Nuclear Information System (INIS)

    Villa, Elena; Rios, Paulo R.

    2009-01-01

    A rigorous mathematical approach based on stochastic geometry concepts is presented to extend previous Johnson-Mehl, Avrami, Kolmogorov treatment of transformation kinetics to situations in which nuclei are not homogeneously located in space but are located in clusters. An exact analytical solution is presented here for the first time assuming that nucleation sites follow a Matern cluster process. The influence of Matern cluster process parameters on subsequent growth kinetics and the microstructural path are illustrated by means of numerical examples. Moreover, using the superposition principle, exact analytical solutions are also obtained when nucleation takes place by a combination of a Matern cluster process and an inhomogeneous Poisson point process. The new solutions presented here significantly increase the number of exactly solvable cases available to formal kinetics.

    The main contribution of radioisotopes to the development of a new discipline, cell population kinetics, was shown. The aim of this science is to establish, for each tissue of the organism, the life span of its component cells and the mechanisms governing its growth, its differentiation and its homeostasis with respect to outside attacks. Labelling techniques have been used to follow the cells during these various processes. The case of non-dividing cells was considered first, taking as example, the red blood cells of which the lifetime was studied, after which the case of proliferating cells was examined using 14 C- or tritium-labelled thymidine. The methods used to measure the cell cycle parameters were described: labelled-mitosis curve method, double-labelling and continuous labelling methods, proliferation coefficient measurement. Cell kinetics were shown to allow an interpretation of radiobiological data. Finally the practical value of cell kinetics research was shown [fr

    Full Text Available This paper discusses development of modernization processes in the Russian industrial enterprises. The object of the current study is the JSC "Perm Company of petroleum machinery-producing industry". It has been manufacturing oilfield service products of various kinds. It is shown that the impact of modernization on the enterprise depends not only on the local effectiveness of selected solutions, but also on the overall strategy of sustainable development. Modernization is a strategic planning tool. Taking into account the need for a comprehensive approach to strategic development and modernization, the top five stages of the development strategy of the company were mentioned: 1 analysis of internal and external environment; 2 definition of the mission and goals; 3 choice of strategy and baseline scenarios; 4 development of basic strategy; 5 implementation of the strategy. At each stage, methods and tools for strategic planning, as well as the tools of modernization are defined. The relationship between modernization and development strategy of the company is shown. It was revealed that an integrated approach to the modernization and incremental implementation are the basics for the use of a hierarchical system of optimization models to describe the process of manufacturing company modernization. As the target model of the upper level, financial performance of the company is defined. This approach has the following advantages over the point upgrading - reducing the probability of omission of important limitations and ineffective use of resources during the transition to modernization of the company. Basing on the main strategic goals, main directions and tasks of modernization, which are integrated into the tree ends were formed. A thesis was substantiated that he essence of modernization lies in the continuity of mutually complex processes of improving all its directions.

    The kinetics of the hydrogenation/deuteration reaction of graphene was studied by time-dependent x-ray photoemission spectroscopy (XPS). The graphene layer was then exposed to hydrogen or deuterium atomic gas beams, obtained by thermal cracking in a tungsten capillary at T=3000 K. After each step XPS of the C1s line was performed in order to measure H/C and D/C ratios. We have observed a strong kinetic isotope effect for the hydrogenation/deuteration reaction leading to substantially faster adsorption and higher maximum D/C ratios as compared to H/C (D/C 35% vs. H/C 25%).

    Wing, Thomas J; Haan, Lutana; Ashworth, Lonny J; Anderson, Jeff

    2015-06-01

    The acute respiratory distress syndrome (ARDS) network low tidal-volume study comparing tidal volumes of 12 ml/kg versus 6 ml/kg was published in 2000. The study was stopped early as data revealed a 22% relative reduction in mortality rate when using 6 ml/kg tidal volume. The current generation of critical care ventilators allows the tidal volume to be set during volume-targeted, assist/control (volume A/C); however, some ventilators include options that may prevent the tidal volume from being controlled. The purpose of this bench study was to evaluate the delivered tidal volume, when these options are active, in a spontaneously breathing lung model using an electronic breathing simulator. Four ventilators were evaluated: CareFusion AVEA (AVEA), Dräger Evita® XL (Evita XL), Covidien Puritan Bennett® 840(TM) (PB 840), and Maquet SERVO-i (SERVO-i). Each ventilator was connected to the Hans Rudolph Electronic Breathing Simulator at an amplitude of 0 cm H2O and then 10 cm H2O. All four ventilators were set to deliver volume A/C, tidal volume 400 ml, respiratory rate 20 bpm, positive end-expiratory pressure 5 cm H2O, peak flowrate 60 L/min. The displayed tidal volume was recorded for each ventilator at the above settings with additional options OFF and then ON. The AVEA has two options in volume A/C: demand breaths and V-sync. When activated, these options allow the patient to exceed the set tidal volume. When using the Evita XL, the option AutoFlow can be turned ON or OFF, and when this option is ON, the tidal volume may vary. The PB 840 does not have any additional options that affect volume delivery, and it maintains the set tidal volume regardless of patient effort. The SERVO-i's demand valve allows additional flow if the patient's inspiratory flowrate exceeds the set flowrate, increasing the delivered tidal volume; this option can be turned OFF with the latest software upgrade. Modern ventilators have an increasing number of optional settings. These settings may

  6. Sport and Tourism Between Modernity and Postmodernity

    Lenartowicz Michał

    2016-06-01

    Full Text Available The text presents and analyses manifestations of modernity and postmodernity in the field of competitive and recreational sport, physical education, leisure, and tourism. The paper builds upon an extensive literature survey and presents the concept and key features of postmodern societies and the modernity-postmodernity debate in sports with reference to postmodern tendencies in tourism. We have attempted to determine the proportions of tradition, modernity, and postmodernity in contemporary sport and tourism, keeping in mind that, similarly to contemporary societies as a whole, sport is undoubtedly a mixture of traditional, modern, and Fordist elements with postmodern and post-Fordist features. We present and discuss the prevailing belief that the key elements of leisure sport are mostly postmodern and focused on the notion of individualisation and freedom expressed especially in alternative sports, while commercialised mainstream sport follows the regular mass-media show-business development path, maintaining a significant amount of modern concepts, such as the importance of national identities. Special attention is also paid to the Olympic Games as a specific and very efficient mixture of modernity and postmodernity. More so than at any point in the past, and despite the actual proportions of modernity and postmodernity that it contains, contemporary sport has become an integral part of postmodern societies and their lifestyle, with technology-determined individualisation of sport consumption and leisure sport participation.

  7. Forsmark NPP I and C modernization strategy

    Hallen, J.; Rydahl, I.; Kloow, L.

    2003-01-01

    By the year 2000, the Forsmark NPP was halfway through the planned plant life. As early as 1995, Forsmark realized that the old analog I and C equipment would need to be replaced before 2005. At the Forsmark NPP they had strength of a vision of an integrated modernization and a strategy to reach the vision. Without vision and strategy, the plant could end up with a fragmented plant I and C-architecture that is not cost-effective or operable. This paper will address several questions that led to the current modernization program in Forsmark, the more important questions are: What would happen if the modernization would be postponed? Which main requirements were to be achieved by means of the modernization strategy? The goal of a completed plant modernization program is a totally integrated system solution and what factors were considered during the modernization? How to gain acceptance from the operational staff in designing Control Room and Soft Control Displays? What are the important roles for the staff and organization to reach the end goal? What has been the experience to date and what are the lessons learned? Thanks to the long term co-operation between Forsmark and Westinghouse the modernization has been very successful for both parties. (orig.)

  10. Reframing Romaine Brooks' heroic queer modernism.

    2010-01-01

    Modernism was not a wholesale embracing of Greenberg's definition as abstracting, non-objective, and autonomous. The expatriate U.S. artist and lesbian Romaine Brooks politicized her portraits of females based on a queer combination of the Byronic erotic and Baudelaire's modern dandy. Her execution of her queer modernist aesthetics re-presents female heroes as part of a self-reflective dynamic of lesbian modernity that emphasizes the ambiguity of normative gender binaries and plays with style, personality, and impersonation as disrupting to bourgeoisie mores. My focus is on how Brooks shatters normative conventions of portraiture in her revolutionary critique of heteronormativity.

  11. Spine biomechanics associated with the shortened, modern one-plane golf swing.

    The purpose of this study was to compare kinetic, kinematic, and performance variables associated with full and shortened modern backswings in a skilled group of modern swing (one-plane) golfers. Shortening the modern golf backswing is proposed to reduce vertebral spine stress, but supporting evidence is lacking and performance implications are unknown. Thirteen male golfers performed ten swings of each swing type using their own 7-iron club. Biomechanical-dependent variables included the X-Factor kinematic data and spine kinetics. Performance-related dependent variables included club head velocity (CHV), shot distance, and accuracy (distance from the target line). Data were analysed with repeated measures ANOVA with an a priori alpha of 0.05 (SPSS 22.0, IBM, Armonk, NY, USA). We found significant reductions for the X-Factor (p < 0.05) between the full and shortened swings. The shortened swing condition ameliorated vertebral compression force from 7.6 ± 1.4 to 7.0 ± 1.7 N (normalised to body weight, p = 0.01) and significantly reduced CHV (p < 0.05) by ~2 m/s with concomitant shot distance diminution by ~10 m (p < 0.05). Further research is necessary to examine the applicability of a shortened swing for golfers with low back pain.

  12. Historical development of modern anesthesia.

    Of all milestones and achievements in medicine, conquering pain must be one of the very few that has potentially affected every human being in the world. It was in 1846 that one of mankind's greatest fears, the pain of surgery, was eliminated. This historical review article describes how the various elements of anesthesiology (gasses, laryngoscopes, endotracheal tubes, intravenous medications, masks, and delivery systems) were discovered and how some brilliant entrepreneurs and physicians of the past two centuries have delivered them to humanity. One name stands out amongst all others when the founder of modern anesthesia is discussed, William T.G. Morton (1819-1868). A young Boston Dentist, Dr. Morton had been in the search for a better agent than what had been used by many dentists: nitrous oxide. With Dr. Morton's tenacity driven by enthusiasm and discovery, he and renowned surgeon at Massachusetts General Hospital, John Collins Warren (1778-1856) made history on October 16, 1846 with the first successful surgical procedure performed with anesthesia. Dr. Morton had single-handedly proven to the world that ether is a gas that when inhaled in the proper dose, provided safe and effective anesthesia. One of the first accounts of an endotracheal tube being used for an airway comes from the pediatrician Joseph O'Dwyer (1841-1898). He used the metal "O'dwyer" tubes in diphtheria cases and passed them into the trachea blindly. Adding a cuff to the tube is credited to Arthur Guedel (1883-1956) and Ralph M. Waters (1883-1979) in 1932. This addition suddenly gave the practitioner the ability to provide positive pressure ventilation. The anesthesiologist Chevalier Jackson (1865-1958) promoted his handheld laryngoscope for the insertion of endotracheal tubes and its popularity quickly caught hold. Sir Robert Reynolds Macintosh's (1897-1989) breakthrough technique of direct laryngoscopy came after being appointed Nuffield professor of anesthetics at the University of Oxford

    2000-01-01

    We continue the description of the dynamics of unstable particles within the real-time formulation of nonequilibrium field theory initiated in a previous paper . There we suggest to use Baym's PHI-functional method in order to achieve approximation schemes with 'built in' consistency with respect to conservation laws and thermodynamics even in the case of particles with finite damping width. Starting from Kadanoff-Baym equations we discuss a consistent first order gradient approach to transport which preserves the PHI-derivable properties. The validity conditions for the resulting quantum four-phase-space kinetic theory are discussed under the perspective to treat particles with broad damping widths. This non-equilibrium dynamics naturally includes all those quantum features already inherent in the corresponding equilibrium limit (e.g. Matsubara formalism) at the same level of PHI-derivable approximation. Various collision-term diagrams are discussed including those of higher order which lead to memory effects. As an important novel part we derive a generalized nonequilibrium expression for the kinetic entropy flow, which includes contributions from fluctuations and mass-width effects. In special cases an H-theorem is derived implying that the entropy can only increase with time. Memory effects in the kinetic terms provide contributions to the kinetic entropy flow that in the equilibrium limit recover the famous bosonic type T 3 lnT correction to the specific heat in the case of Fermi liquids like Helium-3

    Full Text Available Grounded on Bauman’s thought, the present paper focuses on the constitution of social legitimacy and identity of Physical Education in the context of transition from solid to liquid modernity. This thought favors the understanding of the nature of the crisis that has crossed the identity discourse of Physical Education. The text signals the limits and possibilities of both the modern and the post-modern educational discourses. In this context, it describes a modern scenario that is marked by two distinct moments, the one of modernity at its solid stage, and that of modernity at its liquid stage. The first one, of solid modernity, social condition of surveillance, rationalization and control, performs the functional / adaptive role of putting everyone under the same rigid order (managed society. The second one, of liquid modernity, of the social condition of insignificance and irrationalism, plays the functional role of putting and keeping everyone under the same flexible Market disorder. From the scientific, mechanic focus of both the body and the physical education in solid modernity we have moved to the relativist and esthetic focus of body and physical education in liquid modernity.

    Full Text Available This article evaluates an emerging body of historical scholarship that challenges prevailing views of the primacy of rural conditions in southern lynching by positing that it was symbiotically associated with the processes of modernization underway in the region in the decades around 1900. Statistical analyses of lynching data that differentiate among events according to communal participation, support, and ceremony in Georgia and Louisiana from 1882 to 1930 and local-level indices of modernization (urbanization, rural depopulation, industrialization, agricultural commercialization, and dissolution of traditional family roles yield results that both support and contradict such a modernization thesis of lynching. The findings imply that the consequences of the social transformation in the South coinciding with the lynching era were not uniform throughout the region with regard to racial conflict and violence and that broad arguments proposing an intrinsic connection between modernization and lynchings therefore are overstated.

    Full Text Available The purpose of this study is to examine the historical factors which affected the rise of modern higher education during the late Choson period (1880-1910, and to analyze the implications of these historical factors on educational policies in contemporary higher education in Korea. The rise of modern higher education in Korea can be viewed as occurring in three principal phases: Confucian Choson Royal Government, Western Christian missionaries, and patriotic nationalists. The author points out that the major historical factors influencing the development of modern higher education were Confucianism, Christianity, and Korean nationalism. In particular, Confucianism and Christianity have had substantial impacts on the planning of educational policies in contemporary Korean higher education; the former is viewed as an original source of educational enthusiasm which has expanded Korean higher education, and the latter a matrix of modern Korean higher education which has embodied educational enthusiasm.

  11. Modern Canonical Quantum General Relativity;

    International Nuclear Information System (INIS)

    Kiefer, Claus

    2008-01-01

    The open problem of constructing a consistent and experimentally tested quantum theory of the gravitational field has its place at the heart of fundamental physics. The main approaches can be roughly divided into two classes: either one seeks a unified quantum framework of all interactions or one starts with a direct quantization of general relativity. In the first class, string theory (M-theory) is the only known example. In the second class, one can make an additional methodological distinction: while covariant approaches such as path-integral quantization use the four-dimensional metric as an essential ingredient of their formalism, canonical approaches start with a foliation of spacetime into spacelike hypersurfaces in order to arrive at a Hamiltonian formulation. The present book is devoted to one of the canonical approaches-loop quantum gravity. It is named modern canonical quantum general relativity by the author because it uses connections and holonomies as central variables, which are analogous to the variables used in Yang-Mills theories. In fact, the canonically conjugate variables are a holonomy of a connection and the flux of a non-Abelian electric field. This has to be contrasted with the older geometrodynamical approach in which the metric of three-dimensional space and the second fundamental form are the fundamental entities, an approach which is still actively being pursued. It is the author's ambition to present loop quantum gravity in a way in which every step is formulated in a mathematically rigorous form. The formal Leitmotiv of loop quantum gravity is background independence. Non-gravitational theories are usually quantized on a given non-dynamical background. In contrast, due to the geometrical nature of gravity, no such background exists in quantum gravity. Instead, the notion of a background is supposed to emerge a posteriori as an approximate notion from quantum states of geometry. As a consequence, the standard ultraviolet divergences of

    Accurate simulations of combustion phenomena require the use of detailed chemical kinetics in order to capture limit phenomena such as ignition and extinction as well as predict pollutant formation. However, the chemical kinetic models for hydrocarbon fuels of practical interest typically have large numbers of species and reactions and exhibit high levels of mathematical stiffness in the governing differential equations, particularly for larger fuel molecules. In order to integrate the stiff equations governing chemical kinetics, generally reactive-flow simulations rely on implicit algorithms that require frequent Jacobian matrix evaluations. Some in situ and a posteriori computational diagnostics methods also require accurate Jacobian matrices, including computational singular perturbation and chemical explosive mode analysis. Typically, finite differences numerically approximate these, but for larger chemical kinetic models this poses significant computational demands since the number of chemical source term evaluations scales with the square of species count. Furthermore, existing analytical Jacobian tools do not optimize evaluations or support emerging SIMD processors such as GPUs. Here we introduce pyJac, a Python-based open-source program that generates analytical Jacobian matrices for use in chemical kinetics modeling and analysis. In addition to producing the necessary customized source code for evaluating reaction rates (including all modern reaction rate formulations), the chemical source terms, and the Jacobian matrix, pyJac uses an optimized evaluation order to minimize computational and memory operations. As a demonstration, we first establish the correctness of the Jacobian matrices for kinetic models of hydrogen, methane, ethylene, and isopentanol oxidation (number of species ranging 13-360) by showing agreement within 0.001% of matrices obtained via automatic differentiation. We then demonstrate the performance achievable on CPUs and GPUs using py

  15. Long Day's Journey into Night: Modernism, Post-Modernism and Maternal Loss

    OpenAIRE

    Meaney, Gerardine

    2009-01-01

    Long Day's journey into Night may seem a strange starting place for a feminist analysis of modernism and post-modernism. Yet even the most conservative criticism reads this play as an enactment and embodiment of loss, specifically loss of the mother. That loss is rarely seen in the context of a more general "loss", a cultural loss of legitimacy and authenticity, endemic in and enabling modernism, articulated as "disinheritance" by an Other "coded as feminine."

  16. Modern Technology within the Western Theological Imaginary

    Directory of Open Access Journals (Sweden)

    Neil Turnbull

    2016-03-01

    Full Text Available In this paper, I claim that modern technology possesses certain general ‘onto-formative’ characteristics that indicate that our contemporary technological condition now defies orthodox theoretical forms of comprehension. In the light of this claim, I will propose that any adequate conceptual understanding of modern technics requires a decisive shift of disciplinary register: specifically, towards theology and to the formation of new philosophical paradigms founded upon metaphysically-inspired interpretations of the ‘total significance’ of modern technics. Such theological conceptions, I will argue, emerge from a startling recognition of modern technics’ incipient association with the infinite, the transcendent as well as with its capacity to “bring new worlds into existence”. I attempt this, in the first instance, by drawing upon the work of two major thinkers who I believe paved the way towards just such a theological conception: Martin Heidegger and Ernst Jünger. In a non-standard interpretation of their respective philosophies of technology, I will go on to claim that these two thinkers should be viewed as attempting to find a way towards a “radically conservative” revalorisation of ancient theological truths that they believed could provide 20th century modernity with the philosophical groundwork for a new techno-political order that they posited in contrast to a dying Platonic-Christian civilisation. For both of these thinkers a theological understanding of modern technics created the possibility of a new spiritual condition/zeitgeist where the very idea of modern technology is rearticulated as the focal point of a post-Platonic-Christian social imaginary that they believed to be revolutionary in its necessarily destructive relationship to extant historical worlds and their corresponding traditions. By these lights, I suggest, that modern social imaginary can only be con conceived within a new theological synthesis that

  20. Kinetic approach to relativistic dissipation

    2017-08-01

    Despite a long record of intense effort, the basic mechanisms by which dissipation emerges from the microscopic dynamics of a relativistic fluid still elude complete understanding. In particular, several details must still be finalized in the pathway from kinetic theory to hydrodynamics mainly in the derivation of the values of the transport coefficients. In this paper, we approach the problem by matching data from lattice-kinetic simulations with analytical predictions. Our numerical results provide neat evidence in favor of the Chapman-Enskog [The Mathematical Theory of Non-Uniform Gases, 3rd ed. (Cambridge University Press, Cambridge, U.K., 1970)] procedure as suggested by recent theoretical analyses along with qualitative hints at the basic reasons why the Chapman-Enskog expansion might be better suited than Grad's method [Commun. Pure Appl. Math. 2, 331 (1949), 10.1002/cpa.3160020403] to capture the emergence of dissipative effects in relativistic fluids.

  1. Kinetic theory of tearing instability

    International Nuclear Information System (INIS)

    Hazeltine, R.D.; Dobrott, D.; Wang, T.S.

    1975-01-01

    The guiding-center kinetic equation with Fokker-Planck collision term is used to study, in cylindrical geometry, a class of dissipative instabilities of which the classical tearing mode is an archetype. Variational solution of the kinetic equation obviates the use of an approximate Ohm's law or adiabatic assumption, as used in previous studies, and it provides a dispersive relation which is uniformly valid for any ratio of wave frequency to collision frequency. One result of using the rigorous collision operator is the prediction of a new instability. This instability, driven by the electron temperature gradient, is predicted to occur under the long mean-free path conditions of present tokamak experiments, and has significant features in common with the kink-like oscillations observed in such experiments

    1987-01-01

    This paper presents some preliminary results on the kinetics of Cd(OH)/sub 2/ precipitation, both in the absence and the presence of citric acid as an inhibiting agent. Batch and continuous stirred tank reactor (CSTR) precipitation studies are performed by mixing equal volumes of NaOH and Cd(NO/sub 3/)/sub 2/ solutions, in order to avoid localized supersaturation conditions. The rate of metal removal from the soluble phase is calculated from the mass balance for the CSTR precipitation tests. In addition, precipitation kinetics are studied in terms of nucleation and crystal growth rates, by means of a particle counter that allows a population balance analysis for the precipitation reactor at steady state conditions

    The classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) model, originally formulated for the isothermal condition, is often used in conjunction with additivity principle for modeling the non-isothermal crystallization kinetics. This approach at times results in significant differences between the model prediction and experimental data. In this article, a modification to this approach has been imposed via an additional functional relationship between the activation energy and heating rate. The methodology has been validated with experimental isochronal crystallization kinetic data in Se 71 Te 20 Sb 9 glass and Ge 20 Te 80 systems. It has been shown that the functional relationship between heating rate and activation energy, ascribed to the reduction in apparent activation energy due to increasing non-isothermality, provides better phenomenological description and therefore improves the prediction capability of the JMAK model under isochronal condition

    Pulmonary oxygen uptake (V˙O2) kinetics and heart rate kinetics are influenced by age and fitness. Muscular V˙O2 kinetics can be estimated from heart rate and pulmonary V˙O2. In this study the applicability of a test using pseudo-random binary sequences in combination with a model to estimate muscular V˙O2 kinetics was tested. Muscular V˙O2 kinetics were expected to be faster than pulmonary V˙O2 kinetics, slowed in aged subjects and correlated with maximum V˙O2 and heart rate kinetics. 27 elderly subjects (73±3 years; 81.1±8.2 kg; 175±4.7 cm) participated. Cardiorespiratory kinetics were assessed using the maximum of cross-correlation functions, higher maxima implying faster kinetics. Muscular V˙O2 kinetics were faster than pulmonary V˙O2 kinetics (0.31±0.1 vs. 0.29±0.1 s; p=0.004). Heart rate kinetics were not correlated with muscular or pulmonary V˙O2 kinetics or maximum V˙O2. Muscular V˙O2 kinetics correlated with maximum V˙O2 (r=0.35; p=0.033). This suggests, that muscular V˙O2 kinetics are faster than estimates from pulmonary V˙O2 and related to maximum V˙O2 in aged subjects. In the future this experimental approach may help to characterize alterations in muscular V˙O2 under various conditions independent of motivation and maximal effort. © Georg Thieme Verlag KG Stuttgart · New York.

    1985-01-01

    To study the effects of renal failure on bumetanide kinetics, the authors administered single intravenous doses of 1.0 mg/3.08 microCi 14 C-bumetanide to six healthy subjects and 22 patients with variable degrees of renal failure. The kinetics of 14 C-bumetanide and total 14 C were adequately described by a two-compartment open model in the control subjects and in the patients. The volume of the central compartment and the distribution t1/2 were of the same order in both groups, whereas the mean (+/- SE) volume at steady state was larger (22.1 +/- 1.6 and 16.9 +/- 1.0 L) and the elimination t1/2 was longer (1.9 +/- 0.2 and 1.4 +/- 0.1 hours) in patients with renal failure than in healthy controls. Bumetanide renal clearance was lower (10 +/- 3 and 90 +/- 13 ml/min) in patients than in subjects and correlated with creatinine clearance (r = 0.784) and log serum creatinine level (r = -0.843), whereas nonrenal clearance was significantly higher in the patients (153 +/- 14 and 99 +/- 6 ml/min). Bumetanide total plasma clearance did not significantly change. The non-protein-bound, free fraction of bumetanide was higher in patients and correlated with plasma albumin levels (r = -0.777). The kinetics of total 14 C showed similar but greater changes than those of 14C-bumetanide. Thus the most important changes in bumetanide kinetics in patients with renal failure are low renal clearance and a high free fraction, with a consequent increase in nonrenal clearance, volume of distribution, and elimination t1/2

    We discuss two expressions for the density of kinetic energy which differ by an integration by parts. Using the Wigner transform we shown that the arithmetic mean of these two terms is closely analogous to the classical value. Harmonic oscillator wavefunctions are used to illustrate the radial dependence of these expressions. We study the differences they induce through effective mass terms when performing self-consistent calculations. (author)

The experiments have been carried out within OECD MASCA program and ISTC METCOR, METCOR-P and EVAN projects. It has been shown that the melt oxidation is controlled by an oxidant supply to the melt free surface from the atmosphere, not by the reducer supply from the melt. The project experiments have not detected any input of the zirconium oxidation kinetics into the process chemistry. The completed analysis puts forward a simple analytical model, which gives an explanation of the main features of melt oxidation process. The numerical modeling results are in good agreement with experimental data and theoretical considerations.

    Highlights: • Release of Al corrosion product was measured in simulated post-LOCA sump solutions. • Increased boron was found to enhance Al release kinetics at similar pH. • Models of Al release as functions of time, temperature, and pH were developed. - Abstract: The kinetics of aluminum corrosion product release was examined in solutions representative of post-LOCA sump water for both pressurized water and pressurized heavy-water reactors. Coupons of AA 6061 T6 were exposed to solutions in the pH 7–11 range at 40, 60, 90 and 130 °C. Solution samples were analyzed by inductively coupled plasma atomic emission spectroscopy, and coupon samples were analyzed by secondary ion mass spectrometry. The results show a distinct “boron effect” on the release kinetics, expected to be caused by an increase in the solubility of the aluminum corrosion products. New models were developed to describe both sets of data as functions of temperature, time, and pH (where applicable)

    OKG operates three BWR units of ABB design: Oskarshamn 1 with a net capacity of 440' MW, Oskarshamn 2 of 600 MW and Oskarshamn 3 of 1160 MW. Oskarshamn 1 NPP was commissioned in 1972 as the first commercial nuclear unit in Sweden. After more than twenty years of successful operation, the unit is now also the first reactor in Sweden to undergo a large safety modernization program. In the year 2000 the Oskarshamn 1 NPP will be modernized to a high level of safety standard and ready for operation for another period of at least 20 years. Experience gained can be used when modernizing other NPPs. The investment program for life extension is reasonable and shows that NPPs can be operated with an expected life span of more than 40 years at an ever-increasing safety level and still be very competitive in a deregulated market.

  19. Bolatu's pharmacy theriac in early modern China.

    Science.gov (United States)

    Nappi, Carla

    2009-01-01

    In early modem China, natural history and medicine were shifting along with the boundaries of the empire. Naturalists struggled to cope with a pharmacy's worth of new and unfamiliar substances, texts, and terms, as plants, animals, and the drugs made from them travelled into China across land and sea. One crucial aspect of this phenomenon was the early modern exchange between Islamic and Chinese medicine. The history of theriac illustrates the importance of the recipe for the naturalization of foreign objects in early modem Chinese medicine. Theriac was a widely sought-after and hotly debated product in early modern European pharmacology and arrived into the Chinese medical canon via Arabic and Persian texts. The dialogue between language and material objects was critical to the Silk Road drug trade, and transliteration was ultimately a crucial technology used to translate drugs and texts about them in the early modern world.

    The discovery of a turtle in the Early Jurassic(185 million years before present) Kayenta Formation of northeastern Arizona provides significant evidence about the origin of modern turtles. This new taxon possesses many of the primitive features expected in the hypothetical common ancestor of pleurodires and cryptodires, the two groups of modern turtles. It is identified as the oldest known cryptodire because of the presence of a distinctive cryptodiran jaw mechanism consisting of a trochlea over the otic chamber that redirects the line of action of the adductor muscle. Aquatic habits appear to have developed very early in turtle evolution. Kayentachelys extends the known record of cryptodires back at least 45 million years and documents a very early stage in the evolution of modern turtles.

    Quantum mechanics forms the foundation of all modern physics, including atomic, nuclear, and molecular physics, the physics of the elementary particles, condensed matter physics. Modern astrophysics also relies heavily on quantum mechanics. Quantum theory is needed to understand the basis for new materials, new devices, the nature of light coming from stars, the laws which govern the atomic nucleus, and the physics of biological systems. As a result the subject of this book is a required course for most physics graduate students. While there are many books on the subject, this book targets specifically graduate students and it is written with modern advances in various fields in mind. Many examples treated in the various chapters as well as the emphasis of the presentation in the book are designed from the perspective of such problems. For example, the book begins by putting the Schrodinger equation on a spatial discrete lattice and the continuum limit is also discussed, inspired by Hamiltonian lattice gauge ...

    2010-01-01

    Sandra Harding's newest book, Sciences from Below: Feminisms, Postcolonialities, and Modernities, continues her work in feminist standpoint theory and science and technologies studies, asking how we might judge "good" science. Attentive to race, class, gender, and imperialism, Harding critically examines Northern and Southern sciences and technologies by adopting the perspective of those who see from below. This vision from the peripheries lets Harding question stories of modern scientific progress, revealing a multiplicity of "ethnosciences" and critiquing modernity itself. However, while Harding aims to produce knowledge for the North's others by emphasizing woman's experience, she fails to question the category "woman," ignoring contemporary transgender and queer scholarship. Further, it is Harding's care for the North's subjugated others that motivates her writing, revealing that the struggle to achieve the standpoint "from below" so critical to her project is fueled by what her ally Maria Puig de la Bellacasa would term not thinking from, but thinking with, or, more precisely, "thinking with care."

  6. Defective modernization and health in Mexico.

    Simonelli, J M

    1987-01-01

    This paper uses data gathered in a semi-arid, mountain region of the border state of Sonora, Mexico to illustrate that modernization and the importation of urban ideas and values can influence health status in unexpected ways. It traces the historic process of modernization in a rural municipio, relating this to social promises and economic cycles in Mexico. Modernization is seen to encompass life standard improvements and access to medical care; extension of road and transportation systems; and the widespread availability of information and education, as well as lifestyle changes required to incorporate these 'urban' influences. Reviewing the link between climate and health in arid lands, the paper notes that such modernization can be a well-meaning intrusion upon a set of cultural and social practices which had proved adaptive in dealing with climatic extremes. Initial modernization produces impressive declines in mortality and morbidity, as illustrated in an analysis of mortality figures and causes in relation to age cohorts and decades for the years 1955-1984. However, reductions in epidermic-related infant mortality are shown to be offset by increases in deaths due to trauma, chronic conditions and endemic disease. An analysis of morbidity for the year 1983-84 indicates that continuing high rates of infectious disease are related to conditions which result from increasingly defective modernization. To maintain technology, including water, electrical, and sewage systems, continual capital expenditure on both the public and private level is required. The economic crisis in Mexico is reducing available funds at a time when the community has adjusted its traditional lifestyle to incorporate technological improvements. In light of this, it is likely that inroads against infectious disease will not just continue to be stalemated, but could actually be reversed. This finding has implications for towns and villages on both sides of the Mexican-American border.

  7. Perspective and Spatiality in the Modern Age

    Full Text Available the domain of Art critique and becoming a philosophical argument. How can we think of Perspective as symbolic Form? Is Perspective really a symbolic form? Why is Perspective so important? Because at the beginning of the Modern Age, Perspective as spiritual figure grounds many symbolic or even many scientific constructions. We could we say that perspective open the foundation of modern science as such. The “Geometrization” of Vision, beginning with perspective, will be for us the interpretative key in order to understand the Modern Age as a whole.  This understanding will allow us to understand the anthropologic dimension arising from the Modern Age, called „Perspectivism“. Assuming that perspective was neither only an invention of painting nor of geometry nor of philosophy, taken as singular fields of human inquiry, we will try to sketch the genesis of “perspective” from an interdisciplinary point of view. By doing so, we will also try to fix its deep significance for the anthropology of the Modern Age. Living and feeling in a perspectival world is the real invention of the Modern Age, one that overcame the closed Cosmos of the Middle Ages in order to reveal to mankind its own potential. Our interdisciplinary approach will proceed from many points of view (history of art, science, theology, anthropology and converge on the idea of a new kind of human experience. Such an interdisciplinary approach will open new questions about our present time. Are we justified in thinking of our experience today as perspectival? What does it mean today to think from perspectives in the manifold dimensions of our living and to face to the complexity of our times?

What methods of increasing the level of media literacy of teachers and students should optimally use?As the purpose of this study the authors can see in the development and presentation of an optimal model of media space for modern educational institutions which will take into account not only the changes in the education process, but also the needs of the modern audience – teachers, students, parents, and educational partners. The resources of “Moscow e-school” become part of the educational media sphere of modern educational organizations.Resources and methods: resources of an educational institution, namely, social media, blogs and microblogs, users’ accounts, channels, educational platforms, which present the work of educators. The importance of analyzing media of the modern educational institution is that media-education serves as a pedagogical system, allowing the use of modern techniques and technologies through the development of critical thinking, which occurs under the influence of information flows. In this regard, there is a need for the comprehensive approach to the media organization in the modern school. An integral element of the complex approach is the creation of conditions for the development of media literacy for teachers and learners.The result of this research is the optimal model of media space for the modern school, which includes social networking profiles, microblogging, blogs, users’ accounts, and web resources, each of which has its own purpose and functional features.As a conclusion we can note that one of the core values of the media model is the development of creative and critical thinking, the acquisition of experience and tools of media, independent search, the ability to use information flows for the effective communication, solving educational and cognitive

    Some ideas on modern dimensioning criteria are given and their advantages with regard to both safety and economy are shown. In general these criteria result from considerations on possible damage to the apparatus in service and the modes of breakdown liable to follow. They are general enough to allow for a variety of dimensioning methods both experimental and theoretical, with special reference to modern computerized digital analysis techniques. As a practical example however some notions are given on the simplest means of computing dimensions in accordance with these criteria [fr

    Full Text Available It is not widely known that Dimitri Mitropoulos first public appearances in Greece were as a composer. His early works (ca. 1912-1924, distinguished by the blend of elements of the late-romantic style with intensely impressionistic references, reflect the search for a personal, 'advanced' harmonic musical language. In his works written after 1924, Mitropoulos abandons tonality and adopts more modern idioms of composition (atonality and 12-tone method. He is the first Greek composer to follow the modern musical tendencies of Europe, when music by Manolis Kalomiris and the other composers of the Greek National School was dominant in Greece.

  1. Nonlinear Kinetics on Lattices Based on the Kinetic Interaction Principle

    Directory of Open Access Journals (Sweden)

    Giorgio Kaniadakis

    2018-06-01

    Full Text Available Master equations define the dynamics that govern the time evolution of various physical processes on lattices. In the continuum limit, master equations lead to Fokker–Planck partial differential equations that represent the dynamics of physical systems in continuous spaces. Over the last few decades, nonlinear Fokker–Planck equations have become very popular in condensed matter physics and in statistical physics. Numerical solutions of these equations require the use of discretization schemes. However, the discrete evolution equation obtained by the discretization of a Fokker–Planck partial differential equation depends on the specific discretization scheme. In general, the discretized form is different from the master equation that has generated the respective Fokker–Planck equation in the continuum limit. Therefore, the knowledge of the master equation associated with a given Fokker–Planck equation is extremely important for the correct numerical integration of the latter, since it provides a unique, physically motivated discretization scheme. This paper shows that the Kinetic Interaction Principle (KIP that governs the particle kinetics of many body systems, introduced in G. Kaniadakis, Physica A 296, 405 (2001, univocally defines a very simple master equation that in the continuum limit yields the nonlinear Fokker–Planck equation in its most general form.

    Kinetics of geochemical reactions has been increasingly used in numerical models to simulate coupled flow, mass transport, and chemical reactions. However, the kinetic data are scattered in the literature. To assemble a kinetic dataset for a modeling project is an intimidating task for most. In order to facilitate the application of kinetics in geochemical modeling, we assembled kinetics parameters into a database for the geochemical simulation program, PHREEQC (version 3.0). Kinetics data were collected from the literature. Our database includes kinetic data for over 70 minerals. The rate equations are also programmed into scripts with the Basic language. Using the new kinetic database, we simulated reaction path during the albite dissolution process using various rate equations in the literature. The simulation results with three different rate equations gave difference reaction paths at different time scale. Another application involves a coupled reactive transport model simulating the advancement of an acid plume in an acid mine drainage site associated with Bear Creek Uranium tailings pond. Geochemical reactions including calcite, gypsum, and illite were simulated with PHREEQC using the new kinetic database. The simulation results successfully demonstrated the utility of new kinetic database.

    The Gorkov equations are derived for a general non-equilibrium system. The Gorkov factorization is generalized by the cumulant expansion of the 2-particle correlation and by a generalized Wick theorem in the case of a perturbation expansion. A stationary solution for the Green functions in the Schwinger-Keldysh formalism is presented taking into account pairing correlations. Especially the effects of collisional broadening on the spectral functions and Green functions is discussed. Kinetic equations are derived in the quasi-particle approximation and in the case of particles with width. Explicit expressions for the self-energies are given. (orig.)

    To help achieve the quantitative and mechanistic understanding of these processes, the kinetic theory of radiation effects has been developed in the DOE basic energy sciences radiation effects and fusion reactor materials programs, as well as in corresponding efforts in other countries. This discipline grapples with a very wide range of phenomena and draws on numerous sub-fields of theory such as defect physics, diffusion, elasticity, chemical reaction rates, phase transformations and thermodynamics. The theory is cast in a mathematical framework of continuum dynamics. Issues particularly relevant to the present inquiry can be viewed from the standpoints of applications of the theory and areas requiring further progress

    2014-01-01

    Since the publication of Leonor Michaelis and Maude Menten's paper on the reaction kinetics of the enzyme invertase in 1913, molecular biology has evolved tremendously. New measurement techniques allow in vivo characterization of the whole genome, proteome or transcriptome of cells, whereas the classical enzyme essay only allows determination of the two Michaelis-Menten parameters V and K(m). Nevertheless, Michaelis-Menten kinetics are still commonly used, not only in the in vitro context of enzyme characterization but also as a rate law for enzymatic reactions in larger biochemical reaction networks. In this review, we give an overview of the historical development of kinetic rate laws originating from Michaelis-Menten kinetics over the past 100 years. Furthermore, we briefly summarize the experimental techniques used for the characterization of enzymes, and discuss web resources that systematically store kinetic parameters and related information. Finally, describe the novel opportunities that arise from using these data in dynamic mathematical modeling. In this framework, traditional in vitro approaches may be combined with modern genome-scale measurements to foster thorough understanding of the underlying complex mechanisms. © 2013 FEBS.

    Neubauer, Simon; Hublin, Jean-Jacques; Gunz, Philipp

    2018-01-01

    Modern humans have large and globular brains that distinguish them from their extinct Homo relatives. The characteristic globularity develops during a prenatal and early postnatal period of rapid brain growth critical for neural wiring and cognitive development. However, it remains unknown when and how brain globularity evolved and how it relates to evolutionary brain size increase. On the basis of computed tomographic scans and geometric morphometric analyses, we analyzed endocranial casts of Homo sapiens fossils ( N = 20) from different time periods. Our data show that, 300,000 years ago, brain size in early H. sapiens already fell within the range of present-day humans. Brain shape, however, evolved gradually within the H. sapiens lineage, reaching present-day human variation between about 100,000 and 35,000 years ago. This process started only after other key features of craniofacial morphology appeared modern and paralleled the emergence of behavioral modernity as seen from the archeological record. Our findings are consistent with important genetic changes affecting early brain development within the H. sapiens lineage since the origin of the species and before the transition to the Later Stone Age and the Upper Paleolithic that mark full behavioral modernity.
