Full Text Available The content of marketing is countinously redefined and reflected in new concepts, therefore leading to the development of a new concept the modern marketing. The modern marketing has as orientation and tendency the concept of internal marketing, understood as an extension of the vision, marketing philosophy on persons and networks within companies. The concept, at large, is reflected by the apparition and development of specific instruments: integrated marketing, integrated marketing communication, management of the supply-sales relationship. Integrated marketing is the concept that is based on defining marketing as a philosophy, optic, vision onall activities of the company and especially the difficulty and inefficiency of cooperation as a modality to implement this concept. This assessment raises the problem of using the modern marketing in education, as a necessity to modernize the management system and also the educational system.

Full Text Available New business conditions, in which the presence of turbulent changes in the environment are extremely obvious, demand, much more than before, relevant and reliable information which represent an essential support for the management in all the stages of decision making processes. In the countries with developed market and competitive economies, new approaches, philosophies, concepts and techniques in the field of expense accounting appear. The development of high technology businesses and the appearance of business globalisation raise the question of the quality of accounting information obtained using traditional methods of cost accounting and it is necessary to change the concept of establishing product costs. According to this, management accounting should ensure an informational support for managing businesses which are based on customers' demands, internal processes, continuous business improvement etc. It is only possible with the application of modern concepts of cost accounting, which will ensure efficient of cost management and business management in modern business conditions.

The Transition and Adoption to Modern Programming Concepts for Scientific Computing in Fortran

Charles D. Norton

2007-01-01

Full Text Available This paper describes our experiences in the early exploration of modern concepts introduced in Fortran90 for large-scale scientific programming. We review our early work in expressing object-oriented concepts based on the new Fortran90 constructs – foreign to most programmers at the time – our experimental work in applying them to various applications, the impact on the WG5/J3 standards committees to consider formalizing object-oriented constructs for later versions of Fortran, and work in exploring how other modern programming techniques such as Design Patterns can and have impacted our software development. Applications will be drawn from plasma particle simulation and finite element adaptive mesh refinement for solid earth crustal deformation modeling.

2017-06-01

This research focuses on the problem occurred in the reactive dye synthesis process of a global manufacturer in Thailand which producing various chemicals for reactive dye products to supply global industries such as chemicals, textiles and garments. The product named “Reactive Blue Base” is selected in this study because it has highest demand and the current chemical yield shows a high variation, i.e. yield variation of 90.4% - 99.1% (S.D. = 2.405 and Cpk = -0.08) and average yield is 94.5% (lower than the 95% standard set by the company). The Six Sigma concept is applied aiming at increasing yield and reducing variation of this process. This approach is suitable since it provides a systematic guideline with five improvement phases (DMAIC) to effectively tackle the problem and find the appropriate parameter settings of the process. Under the new parameter settings, the process yield variation is reduced to range between 96.5% - 98.5% (S.D. = 0.525 and Cpk = 1.83) and the average yield is increased to 97.5% (higher than the 95% standard set by the company).

Smart Distribution Networks: A Review of Modern Distribution Concepts from a Planning Perspective

Directory of Open Access Journals (Sweden)

Syed Ali Abbas Kazmi

2017-04-01

Full Text Available Smart grids (SGs, as an emerging grid modernization concept, is spreading across diverse research areas for revolutionizing power systems. SGs realize new key concepts with intelligent technologies, maximizing achieved objectives and addressing critical issues that are limited in conventional grids. The SG modernization is more noticeable at the distribution grid level. Thus, the transformation of the traditional distribution network (DN into an intelligent one, is a vital dimension of SG research. Since future DNs are expected to be interconnected in nature and operation, hence traditional planning methods and tools may no longer be applicable. In this paper, the smart distribution network (SDN concept under the SG paradigm, has presented and reviewed from the planning perspective. Also, developments in the SDN planning process have been surveyed on the basis of SG package (SGP. The package presents a SDN planning foundation via major SG-enabling technologies (SGTF, anticipated functionalities (SGAF, new consumption models (MDC as potential SDN candidates, associated policies and pilot projects and multi-objective planning (MOP as a real-world optimization problem. In addition, the need for an aggregated SDN planning model has also been highlighted. The paper discusses recent notable related works, implementation activities, various issues/challenges and potential future research directions; all aiming at SDN planning.

Modern Social Science Concepts, Proportionate Reciprocity, Modesty, and Democracy

Directory of Open Access Journals (Sweden)

Gerasimos T. SOLDATOS

2014-06-01

Full Text Available Proportionate Reciprocity, Modesty, and Democracy, are the key concepts in Aristotle’s economics of exchange. The following correspondence of these concepts with modern social science may be contemplated: (a Ideally, reciprocal justice in bilateral bargaining to minimize expenditure given utility levels results in Pareto-efficient, envy-free, equitable outcomes. (b Practically, bargaining under the threat or actual recontracting may act as a surrogate of reciprocal justice, leading to an N-person contract topology. (c But, recontracting is subject to practical limitations too, in which case near-reciprocal justice/general equilibrium outcomes may be fostered if, as a surrogate of recontracting, modesty in interaction is exhibited in an evolutionarily-stable-strategy fashion. (d That is, incomplete recontracting amounts to asymmetric agent-type information, which in turn lays the ground for injustices; the same lack of information prevents rectificatory justice from being efficient and hence, modesty can be efficient only if it operates as a social norm and hence, only in a modest polity, which can be no other than democracy.

A novel concept of QUADRISO particles. Part II: Utilization for excess reactivity control

Talamo, Alberto, E-mail: alby@anl.go [Nuclear Engineering Division, Argonne National Laboratory, 9700 South Cass Avenue, Argonne, IL 60439 (United States)

2010-07-15

In high temperature reactors, burnable absorbers are utilized to manage the excess reactivity at the early stage of the fuel cycle. In this paper QUADRISO particles are proposed to manage the initial excess reactivity of high temperature reactors. The QUADRISO concept synergistically couples the decrease of the burnable poison with the decrease of the fissile materials at the fuel particle level. This mechanism is set up by introducing a burnable poison layer around the fuel kernel in ordinary TRISO particles or by mixing the burnable poison with any of the TRISO coated layers. At the beginning of life, the initial excess reactivity is small because some neutrons are absorbed in the burnable poison and they are prevented from entering the fuel kernel. At the end of life, when the absorber is almost depleted, more neutrons stream into the fuel kernel of QUADRISO particles causing fission reactions. The mechanism has been applied to a prismatic high temperature reactor with europium or erbium burnable absorbers, showing a significant reduction in the initial excess reactivity of the core.

Representation of Emotive Concepts in Modern English Fictional Discourse: Gender Approach

Directory of Open Access Journals (Sweden)

Anna I. Dzyubenko

2016-09-01

Full Text Available The article reveals the narrative strategies that are applied by the two modern much written about female authors – S. Kinsella and E. Gilbert – that help them create a unique, at times even autonomous world of a female protagonist embodying a concept of a modern woman. By defining the types of emotions introduced to the English female discourse and by determining the set of their verbal realizations grouped in clusters, the author of the article investigates the grammatical structure of the texts, so-called ‘loaded’ with emotions, thus describing the pragmatic potential of the linguistic units through which the text category of emotiveness is realized. The author states the indisputable likeness of the ‘emotional’ palette found in the female narrations that reveals itself in the females’ going through the same emotional ups and downs, through dissatisfaction with herself and with the world around, finally, through overcoming despair and depression and thus coming to happiness and psycho-emotional tranquility. The paper also offers a set of emotive concepts that are most frequently represented in “Undomestic Goddess” and “Eat. Pray. Love” novels alongside with the description of contextual background that made their objectivization within the works mentioned logical and possible. Finally, the article suggests an interpretative view on a woman acting as a protagonist in the narration and as a fictional embodiment of a real typical female.

Modernity: Are Modern Times Different?

Directory of Open Access Journals (Sweden)

Lynn Hunt

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.

Origin and concept of medicine food homology and its application in modern functional foods.

Science.gov (United States)

Hou, Yan; Jiang, Jian-Guo

2013-12-01

The viewpoints of "medicine food homology" (MFH) conform to today's food requirements of returning to a natural and green healthy life. This paper aims to introduce the concept of MFH and its origin and evolution, and analyze the relationship between food and Chinese medicine. In this review, more than 80 MFH materials approved by China's Ministry of Health are listed and their effective ingredients are summarized in detail. Their treatment mechanism in TCM and western medicine are summarized too. Moreover, some new MFH resources that have been gradually developed are also introduced. MFH materials are a treasure house of functional factors for current functional foods. Innovative ideas for the development of MFH resources in current functional foods are prospected and discussed, such as taking advantage of Chinese diet theory, building a database for MFH varieties and developing new methods and technologies. At present, modern research for the development of MFH functional foods is still in its primary stage, there is still much work required in the popularization of the MFH concept and the development of new products. Knowledge and technological innovations in this area should be accelerated in the future to promote the modernization of MFH.

THE DEMAND FOR A NEW CONCEPT OF ANTHROPOLOGY IN THE EARLY MODERN AGE: THE DOCTRINE OF HUME

Directory of Open Access Journals (Sweden)

A. M. Malivskyi

2016-12-01

Full Text Available Purpose. The purpose of the investigation is to outline the main points of Hume’s interpretation of the basic anthropological project of the era based on radical cultural transformations of the early modern age; to represent a modern vision of Hume's anthropology as a response to the demand of the era and necessity to complete its basic project. Methodology. The research was based on phenomenological and hermeneutic approaches. Originality. Contemporary understanding of the position of anthropological project in Hume's philosophy is regarded as unsatisfactory by the author. Development of the basic project as anthropological is rooted in scientific revolution and needs to be continued and completed. Contemporary prevalence of deanthropogical versions of Hume's philosophy is the result of underestimated significance of the concept of nature in the broad sense. According to the philosopher's texts, heuristic potential of Hume's position is emphasized by the author. The modern version of the basic project in the early modern age is criticized and demands significant changes to become anthropological. Findings. Modern perception of Hume’s philosophy as an anthropological project is unsatisfactory in terms of historical and philosophical science and needs detailed analysis. In order to understand the conditions of anthropological project significance, it is advisable to focus on: a scientific revolution and the necessity to complete it; b determine the role of the concept of nature in its broad sense. Nowadays the way of Hume's rethinking of the basic project of modern philosophy as insufficiently anthropological is quite heuristic. Empiricism, dogmatism, superstition and skepticism are the manifestations of the latter. For Hume, the era was as an incomplete anthropological project and its legacy as the most complete form of explication. Today the interest in the phenomenon of a human provides a reasonable basis to define that modern period is

Anthropology and Multiple Modernities

DEFF Research Database (Denmark)

Thomassen, Bjørn

“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...

Modern history of surgical management of lung abscess: from Harold Neuhof to current concepts.

Science.gov (United States)

Schweigert, Michael; Dubecz, Attila; Stadlhuber, Rudolf J; Stein, Hubert J

2011-12-01

Harold Neuhof was one of the pioneers of thoracic surgery in the early decades of the last century. Inspired by his preceptor Howard Lilienthal he proposed an entirely new concept for surgery on acute lung abscess. The aim of his one-stage procedure was adequate drainage of the abscess cavity. His approach proved to be the first major breakthrough in the treatment of acute lung abscess. Therapy of pulmonary abscess was again radically changed by the advent of antibiotics in the late 1940s. However, the basic principles of Neuhof's concept still influence modern-day management of putrid lung abscess. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Full Text Available The word “market” is at the core of the process of modernization in Russia, especially in regard to the economic aspects of modernization. This article analyzes the usage of the word “market” (rynok in Russian in the metropolitan and provincial press in the Soviet Union and in post-Soviet Russia from 1990 to 2010. “Market” has been a keyword — in the dictionary sense of a word, expression, or concept of particular importance or significance — in the Russian press over the past twenty years: this is evident in its frequency and in the range of contexts in which it is used. In this article, I analyze the relationship of language and society by studying the usage of the word “market” (rynok in the late Soviet and post-Soviet Russian press since 1990. I examine how the word takes on new meanings, and how its changing usage is related to the changing social and political roles of print media in a modernizing environment. The material studied consists of newspaper and magazine texts collected by a search of the Integrum database. The examples are taken from ten selected publications: the nationally distributed magazines Vokrug sveta, Ogonek, Kommersant-Weekly, and Kommersant Dengi; the nationally distributed newspapers Nezavisimaia gazeta, Rossii- skaia gazeta, and Vedomosti; and the regional newspapers Delovoi Peterburg, Nizhegor-odskie novosti, and Cheliabinskii rabochii

Reactive oxygen species in disease: Rebuttal of a conventional concept

Full Text Available The production of intracellular reactive oxygen species and reactive nitrogen species has long been proposed as leading to the random deleterious modification of macromolecules (i.e., nucleic acids, proteins with an associated progressive development of the age associated systemic diseases (e.g., diabetes, Parkinson’s disease as well as contributing to the ageing process.   Superoxide anion (hydrogen peroxide and nitric oxide (peroxynitrite comprise regulated intracellular second messenger pro-oxidant systems, with specific sub-cellular locales of production and are essential for the normal function of the metabolome and cellular electro-physiology.  We have posited that the formation of superoxide anion and its metabolic product hydrogen peroxide, and nitric oxide, do not conditionally lead to random damage of macromolecular species such as nucleic acids or proteins.  Under normal physiological conditions their production is intrinsically regulated that is very much consistent with their second messenger purpose of function.   We further propose that the concept of an orally administered small molecule antioxidant as a therapy to abrogate free radical activity (to control oxidative stress is a chimera.  As such we consider that free radicals are not a major overwhelming player in the development of the chronic diseases or the ageing process.

The Imaginary Significations of Modernity

Carleheden, Mikael

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.

The Eisenhart lift: a didactical introduction of modern geometrical concepts from Hamiltonian dynamics

International Nuclear Information System (INIS)

Cariglia, Marco; Alves, Filipe Kelmer

2015-01-01

This work originates from part of a final year undergraduate research project on the Eisenhart lift for Hamiltonian systems. The Eisenhart lift is a procedure to describe trajectories of a classical natural Hamiltonian system as geodesics in an enlarged space. We point out that it can be easily obtained from basic principles of Hamiltonian dynamics, and as such it represents a useful didactical way to introduce graduate students to several modern concepts of geometry applied to physics: curved spaces, both Riemannian and Lorentzian, conformal transformations, geometrization of interactions and extra dimensions, and geometrization of dynamical symmetries. For all these concepts the Eisenhart lift can be used as a theoretical tool that provides easily achievable examples, with the added benefit of also being a topic of current research with several applications, among which are included the study of dynamical systems and non-relativistic holography.

Feyerabend's 'The concept of intelligibility in modern physics' (1948).

Science.gov (United States)

Kuby, Daniel

2016-06-01

This essay introduces the transcription and translation of Paul Feyerabend's Der Begriff der Verständlichkeit in der modernen Physik [The concept of intelligibility in modern physics] (1948), which is an early essay written by Paul Feyerabend in 1948 on the topic of intelligibility (Verständlichkeit) and visualizability (Anschaulichkeit) of physical theories. The existence of such essay was likely. It is listed in his bibliography as his first publication. Yet the content of the essay was unknown, as no original or copy is extant in Feyerabend's Nachlass and no known published version was available to the community-until now. The essay has both historical and philosophical interest: it is, as far as our current knowledge goes, Feyerabend's earliest extant publication. It documents Feyerabend's philosophical interest as a physicist-to-be, in what he himself called his "positivist" phase; and it gives a rare if fragmentary insight into the early discussions of the 'Third Vienna Circle' and, more generally, the philosophical culture of discussion in Vienna.

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.

How might Levinas' concept of the other's priority and Derrida's unconditional hospitality contribute to the philosophy of the modern hospice movement?

Science.gov (United States)

Floriani, Ciro Augusto; Schramm, Fermin Roland

2010-06-01

Hospitality is commonly referred as one of the meanings of hospes, the Latin word which is also the root of hospice. This article explores the semantics of the word hospice - the seal of identity of modern hospice movement - and attempts to integrate the meaning of hospitality into the modern hospice movement, understood as unconditional reception. Therefore, the article analyzes the concept of unconditional hospitality, developed by Jacques Derrida and that of ethical responsibility proposed by Emmanuel Levinas based on the phenomenological experience of the other. From this point of view, these two concepts tie in with the meaning of hospice, bringing substantial grounding elements to the hospice movement for the construction of a protective ethos.

Pucella, Riccardo

2004-01-01

Reactive systems are systems that maintain an ongoing interaction with their environment, activated by receiving input events from the environment and producing output events in response. Modern programming languages designed to program such systems use a paradigm based on the notions of instants and activations. We describe a library for Standard ML that provides basic primitives for programming reactive systems. The library is a low-level system upon which more sophisticated reactive behavi...

Concept and numerical simulations of a reactive anti-fragment armour layer

Hušek, Martin; Kala, Jiří; Král, Petr; Hokeš, Filip

2017-07-01

The contribution describes the concept and numerical simulation of a ballistic protective layer which is able to actively resist projectiles or smaller colliding fragments flying at high speed. The principle of the layer was designed on the basis of the action/reaction system of reactive armour which is used for the protection of armoured vehicles. As the designed ballistic layer consists of steel plates simultaneously combined with explosive material - primary explosive and secondary explosive - the technique of coupling the Finite Element Method with Smoothed Particle Hydrodynamics was used for the simulations. Certain standard situations which the ballistic layer should resist were simulated. The contribution describes the principles for the successful execution of numerical simulations, their results, and an evaluation of the functionality of the ballistic layer.

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.

A new concept for spatially divided Deep Reactive Ion Etching with ALD-based passivation

Conventional Deep Reactive Ion Etching (DRIE) is a plasma etch process with alternating half-cycles of 1) Si-etching with SF 6 to form gaseous SiF x etch products, and 2) passivation with C 4 F 8 that polymerizes as a protecting fluorocarbon deposit on the sidewalls and bottom of the etched features. In this work we report on a novel alternative and disruptive technology concept of Spatially-divided Deep Reactive Ion Etching, S-DRIE, where the process is converted from the time-divided into the spatially divided regime. The spatial division can be accomplished by inert gas bearing 'curtains' of heights down to ∼20 μm. These curtains confine the reactive gases to individual (often linear) injection slots constructed in a gas injector head. By horizontally moving the substrate back and forth under the head one can realize the alternate exposures to the overall cycle. A second improvement in the spatially divided approach is the replacement of the CVD-based C 4 F 8 passivation steps by ALD-based oxide (e.g. SiO 2 ) deposition cycles. The method can have industrial potential in cost-effective creation of advanced 3D interconnects (TSVs), MEMS manufacturing and advanced patterning, e.g., in nanoscale transistor line edge roughness using Atomic Layer Etching.

“” in Modern Japan: Focusing on the Terminological Introduction of “” and the Complex Formation of Its Concept*

2017-04-01

Full Text Available This paper aims to clarify when the term of Byoin (hospital was introduced and how its concept was developed in modern Japan. The word “Byoin” was introduced in Japan in 1787 for the first time, but it had not been in use until early 1860s. Instead, various medical institutions performing the functions of modern medical facilities, such as Yojosho (A place for preserving health, Shijuku (private school, called by traditional names as ever. Japanese intellectuals already adopted the word Byoin and the concept of western hospital in early 1860s when their national delegates were dispatched to Europe to revise the treaties forged with western powers. Japanese translations of hospital appeared in English-Japanese/Japanese-English dictionaries published in the 1860s. For instance, the word Byoin (hospital in Japanese was first published in a dictionary published in 1867 and unclearly connected to the words, hospital, infirmary. This paper will argue that the concept of Byoin was sophisticated through Meiji government's efforts to implement reforms distinguishing medical facilities based on their capacity of inpatients and quality. The first medical law (Isei proclaimed by the Meiji government in 1874 articulated regulations for a hospital in eight different articles. The government established hospitals in various parts of the country, following its newly established modern medical care policies. However, in this process, Iin (hospital/clinic, another term for “hospital” appeared. Regional differences and financial issues made standardizing the concept of a hospital even more difficult. In response to the widely embedded confusion, the Japanese government made an effort to clarify the concept of a hospital, setting up provisions regarding the size of medical facilities. As a result, the word Byoin finally came to be used for a hospital with more than ten beds, while a clinic with beds below ten was called Shinryojo (clinic. On the other hand

Modernism in Theory and Praxis. The Example of Germany

Directory of Open Access Journals (Sweden)

Christof Dipper

2016-12-01

Full Text Available Starting from a reconstruction of the origins of the concept of “modernity” in the late Nineteenth century and of the different interpretations of it in the context of the German social sciences, the essay articulates its radical ambivalences. After establishing that modernity cannot be measured on a scale of progress, neither can it be identified with a specific value, Christof Dipper suggests that there are many conceptions of modernity as there are societies, and that these are not necessarily following a common path. The concept of modernity, that includes anti-modernity as well, embraces therefore actors, representations, and constellations, offering an overall reading of history.

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.

Hearing the irrational: music and the development of the modern concept of number.

Science.gov (United States)

Pesic, Peter

2010-09-01

Because the modern concept of number emerged within a quadrivium that included music alongside arithmetic, geometry, and astronomy, musical considerations affected mathematical developments. Michael Stifel embedded the then-paradoxical term "irrational numbers" (numerici irrationales) in a musical context (1544), though his philosophical aversion to the "cloud of infinity" surrounding such numbers finally outweighed his musical arguments in their favor. Girolamo Cardano gave the same status to irrational and rational quantities in his algebra (1545), for which his contemporaneous work on music suggested parallels and empirical examples. Nicola Vicentino's attempt to revive ancient "enharmonic" music (1555) required and hence defended the use of "irrational proportions" (proportiones inrationales) as if they were numbers. These developments emerged in richly interactive social and cultural milieus whose participants interwove musical and mathematical interests so closely that their intense controversies about ancient Greek music had repercussions for mathematics as well. The musical interests of Stifel, Cardano, and Vicentino influenced their respective treatments of "irrational numbers." Practical as well as theoretical music both invited and opened the way for the recognition of a radically new concept of number, even in the teeth of paradox.

Full Text Available This article shows that Rousseau political philosophy is inseparable from his social and educational ideas. I evince the relevance of freedom and equality both for the pedagogic sphere than for democracy. Rousseau defended social equality and the rule of law, which are essential dimensions of democratic societies. I argue that he is a pioneer of the notions of early childhood education. He is also precursor of the direct democracy from the political association; which is a base for social cohesion. I argue that Rousseau ideas are useful reference for building an open republic. Then, I argue that these concepts are fundamental for a modern civic education, which is relevant considering the current conservative tendencies in the global crisis.

VERBAL REPRESENTATION OF THE CONCEPT OF POLITENESS AND ITS SPECIFICS IN RUSSIAN AND MODERN HEBREW

Directory of Open Access Journals (Sweden)

Pishchalnikova Vera Anatolyevna

2015-03-01

Full Text Available The authors compare the content of the universal ethic notion of politeness in Russian and Modern Hebrew on the basis of structural research of word's lexical meaning. Politeness is investigated as a basic ethic value that is included into the nucleus of ethnic culture and has certain influence on the content of ethnic worldview. The verbal representation of politeness as an ethic category differs significantly revealing the different structure and specific correlation of semantic components. The authors emphasize that national and cultural specifics of communicative behavior are defined by the different content of the concept of politeness in the communicative consciousness of the representatives of different linguocultures. In the process of communication the members of an ethnos act according to different operational understanding of the politeness assimilated during the social adaptation process. The authors underline that the notions (concepts described by the same word often differ in psychological meaning within the conceptual spheres of different nations. These different parts of ethnosspecific concepts contain significant information and national specifics of communicative behavior, and that is why they are pragmatically relevant. The research of the specifics of politeness concept meaning is a theoretical and pragmatic topic of current importance. The authors describe the first stage of politeness concept modelling based on lexicographic data. By comparing the components of concepts' meaning, that are denominated by comparable words in Russian and Jewish linguocultures, the authors prove the stability of concept's structure as a specific mental unit. The structural and semantic models of ъебйга and вежливость contain discreet components of meaning that are opposed gradually. The authors believe that this could be the indication of certain universal types of relations between word's meaning components.

In Search of the English Sabbat: Popular Conceptions of Witches’ Meetings in Early Modern England

Directory of Open Access Journals (Sweden)

James Sharpe

2013-03-01

Full Text Available This article explores the evidence for belief in the witches’ sabbat in early modern England. England is generally thought of as a country where the concept of the sabbat did not exist, and it was certainly largely absent from elite thinking on witchcraft, as displayed in the witchcraft statutes of 1563 and 1604 and Elizabethan and Jacobean demonological writings. But evidence entering the historical record mainly via deposi- tions taken by justices of the peace suggests that there was a widespread popular belief in the sabbat or in parallel forms of witches’ meetings, evidence that the concept of the sabbat existed in popular culture. In this, the English evidence seems to support Carlo Ginzburg’s model of the sabbat being essentially a popular construction in its origins. The article also examines a play based on one of the historical incidents analysed, Richard Brome and Thomas Heywood’s The Late Lancashire Witches (1634, and uses it as a starting point for a brief discussion of witchcraft motifs in contemporary drama, notably Shakespeare’s Macbeth.

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.

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

Image and Morphology in Modern Theory of Architecture

Science.gov (United States)

Yankovskaya, Y. S.; Merenkov, A. V.

2017-11-01

This paper is devoted to some important and fundamental problems of the modern Russian architectural theory. These problems are: methodological and technological retardation; substitution of the modern professional architectural theoretical knowledge by the humanitarian concepts; preference of the traditional historical or historical-theoretical research. One of the most probable ways is the formation of useful modern subject (and multi-subject)-oriented concepts in architecture. To get over the criticism and distrust of the architectural theory is possible through the recognition of an important role of the subject (architect, consumer, contractor, ruler, etc.) and direction of the practical tasks of the forming human environment in the today’s rapidly changing world and post-industrial society. In this article we consider the evolution of two basic concepts for the theory of architecture such as the image and morphology.

Reactive burn models and ignition & growth concept

Directory of Open Access Journals (Sweden)

Shaw M.S.

2011-01-01

Full Text Available Plastic-bonded explosives are heterogeneous materials. Experimentally, shock initiation is sensitive to small amounts of porosity, due to the formation of hot spots (small localized regions of high temperature. This leads to the Ignition & Growth concept, introduced by LeeTarver in 1980, as the basis for reactive burn models. A homo- genized burn rate needs to account for three meso-scale physical effects: (i the density of active hot spots or burn centers; (ii the growth of the burn fronts triggered by the burn centers; (iii a geometric factor that accounts for the overlap of deflagration wavelets from adjacent burn centers. These effects can be combined and the burn model defined by specifying the reaction progress variable λ = g(s as a function of a dimensionless reaction length s(t = rbc/ℓbc, rather than by specifying an explicit burn rate. The length scale ℓbc(Ps = [Nbc(Ps]−1/3 is the average distance between burn centers, where Nbc is the number density of burn centers activated by the lead shock. The reaction length rbc(t = ∫t0 D(P(t′dt′ is the distance the burn front propagates from a single burn center, where D(P is the deflagration speed as a function of the local pressure and t is the time since the shock arrival. A key implementation issue is how to determine the lead shock strength in conjunction with a shock capturing scheme. We have developed a robust algorithm for this purpose based on the Hugoniot jump condition for the energy. The algorithm utilizes the time dependence of density, pressure and energy within each cell. The method is independent of the numerical dissipation used for shock capturing. It is local and can be used in one or more space dimensions. The burn model has a small number of parameters which can be calibrated to fit velocity gauge data from shock initiation experiments.

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...

Methodology. Theoretical and methodological basis of the research is the work of scientists on marketing problems of the city, theory of I. Budnikevych, identifying the characteristics of territorial marketing (municipal, city marketing within industrial, commodity, sale, classical, social-ethic and partnership conceptions. The authors used the combination of following methods in the process of scientific investigation: method of generalization and scientific abstraction – for concrete definition of notional-categorial apparatus; analytical monographic method – to represent scientific thoughts on the directions of marketing instruments application in the processes of territorial attractiveness management; comparative analysis – to find out the peculiarities of marketing instruments and methods use within the limits of different concepts and at different stages of territorial development. Practical value. It was defined that territorial marketing system allows to expand traditional approaches to the policy of regional and local authority’s attractiveness, supplementing them with modern components and characteristics. Nowadays, the instruments of situational conceptions are still actively applied by homeland and foreign territorial marketing practice, sale conception in particular, which stipulates the direction of territorial authorities’ activity to satisfy territorial needs. The instruments of modern territorial marketing conceptions allow to form and increase the attractiveness of territories for defined target audiences

Sport and Tourism Between Modernity and Postmodernity

Directory of Open Access Journals (Sweden)

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.

Introduction to concurrent throughput-oriented programming with ReactiveX

CERN Multimedia

CERN. Geneva

2017-01-01

C++ collections, like std::vector, contain values distributed in space. However, other values; mouse events, hardware measurements and network packets are examples of values distributed in time. Many algorithms are implemented using the Iterator and Range concepts for values distributed in space. ReactiveX defines the concepts and algorithms for values distributed in time. The ReactiveX concepts and algorithms are implemented in the rxcpp library. The result is safe and clear async code with no visible std::thread or std::mutex.

Introductory concepts

International Nuclear Information System (INIS)

Barnes, W.E.

1983-01-01

Physical theories are commonly classified as being either ''classical'' or ''modern''. The reasons for this distinction are both historical and substantive. Limited in the sophistication of their measuring instruments, early scientists proposed theories appropriate for the description of the simplest and most accessible physical phenomena, e.g., the trajectories of the planets. Because of the class of phenomena observed, certain beliefs came to underlie all classical theories with regard to the nature of time, space, matter, etc. For example, the idea was undisputed that an object has at all times both a definite position and velocity. Not until the interior of the atom and the nature of electromagnetic radiation were explored was it discovered that the concepts of classical physics are inadequate to deal with many phenomena. A reassessment of fundamental postulates led to the formulation of modern physics which, it is believed, successfully treats the behavior of all physical systems. To gain an understanding of the rudiments of modern physics, one proceeds as the early scientists did by first mastering the classical concepts that emerge from their intuitive picture of the world. Modifications of these concepts are subsequently introduced which allow a more accurate treatment of physical phenomena, particularly atomic and nuclear systems

HANS OF THE OTTOMAN PERIOD: AN ANALYSIS OF THE SPATIAL CONCEPT IN FUNCTION OF A MODERN TOURIST PURPOSE

2017-10-01

Full Text Available The highest developed form of a spatial concept of ainn in the urban area of the Ottoman period is the rectangular form of the spatial organization of the hans from the 15th and the 16th centuries. The most important examples are Kurshumlihan, Sulihan and Kapan han in the old bazaar in Skopje, which are part of a complex spatial system of the historical part of the city. According to the urban concept of the Ottoman builders, a group of public buildings has been formed, where mosque, bedesten, hamam, etc. appear beside another. Spatial analysis of auxiliary rooms and overnight accommodation, or open spaces (atrium, porch has a certain specific ratio. The experience of the organization from historical buildings is a valuable experience in terms of balancing different contents of the used space, its purpose and adjustment to the current needs of the object. The experiences from the study of certain spatial elements of the hans and from the analysis of the current tourism development in which they are included, can be applied in the concept of modern tourist objects.

A METHODOLOGY FOR IMPROVING PRODUCTIVITY OF THE EXISTING SHIPBUILDING PROCESS USING MODERN PRODUCTION CONCEPTs AND THE AHP METHOD

2017-01-01

Full Text Available In recent years, shipyards have been facing difficulties in controlling operational costs. To maintain continual operation of all of the facilities, a shipyard must analyze ways of utilizing present production systems for assembling interim vessel products as well as other types of industrial constructions. In the past, new machines continuously improved shipbuilding processes, including software and organizational restructuring, but management continued to search for a modern technological concept that will provide higher productivity, greater profit and overall reduction in costs. In the article the authors suggest implementing Design for Production, Design for Maintainability and Group Technology principles using the Analytical Hierarchy Process (AHP to apply to multi criteria decision making methods as an efficient tool for maintaining international competitiveness in the modern shipbuilding industry. This novel methodology is implemented through four phases. In the first phase, the present situation analysis is suggested for a real shipyard by establishing closest relations among production lines. The second phase presents a constraint analysis that must be evaluated when developing the design solution. The third phase involves generating a typical number of selected alternatives of the Design for Production, Design for Maintainability and Group Technology principles. In the fourth phase, the optimal design solution is selected using the Analytical Hierarchy Process (AHP method. The solution incorporating this modern methodology will improve productivity, profit and lead to decreasing operational costs.

Full Text Available In the article one of the modern approaches to the social structure of the society is considered. The creative class is determined as the main driving force and as a leading social class of modern society. The author studies the history of the concept of creative class, and R. Florida’s concept in particular, and determines its characteristics and peculiarities. The influence of the creative class on the society, on its transformation processes, and the system of social values is analyzed. The role of creative class in developing creative and innovative economy of the post­industrial society era is found out. The author considers the relationship between the creative class and the other social classes of modern society. The essence of the concept of creativity is defined, and one of the most important problems of the modern era that is a constant conflict between creativity and organization is examined. The comparative historical analysis of the so­called «institutional»/ «industrial» and «creative»/ «post­industrial» era is made. The role of the creative class in developing and social changing the modern American society is studied. The questions of forming and developing creative class in modern Ukrainian society are analyzed, and the peculiarities and problems of this process are figured out. The need of state support for forming national creative class, for its strengthening and growth is emphasized.

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.

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.

Digital reactivity meter

Copie, M.; Valantic, B.

1978-01-01

Digital reactivity meters (DRM) are mostly used as measuring instruments, e.g. for calibration of control rods, and there are only a few cases of their incorporation into the control systems of the reactors. To move in this direction there is more development work needed. First of all, fast algorithms are needed for inverse kinetics equations to relieve the computer for more important tasks of reactor model solving in real time. The next problem, currently under investigation, is the incorporation of the reactor thermal-hydraulic model into the DRM so that it can be used in the power range. Such an extension of DHM allows presentation not only of the instantaneous reactivity of the system, but also the inserted reactivity can be estimated from the temperature reactivity feed-backs. One of the applications of this concept is the anomalous digital reactivity monitor (ADRN) as part of the reactor protection system. As a solution of the first problem, a fast algorithm for solving the inverse kinetics equations has been implemented in the off-line program RODCAL on CDC 1700 computer and tested for its accuracy by performing different control rod calibrations on the reactor TRIGA

Religious Fundamentalism/Religious Modernism: Conceptual Adversaries or Ambivalent Phenomena?

Directory of Open Access Journals (Sweden)

D. GOLOVUSHKIN

2015-02-01

Full Text Available Both religious modernism and religious fundamentalism appeared as problems in academic and theological literature at the beginning of the 20th century. They came about as the result of the dynamic development of modernistic ideology in Russia, the United States, Western Europe and the Islamic world. Today, the concepts of religious modernism and religious fundamentalism are widely used to describe religious processes and phenomena which are the result of interaction between religion (as a dynamic spiritual and social subsystem and society - as a social system experiencing evolution. The concept of religious modernism is traditionally associated with religious renewal, the contemporary world, and innovation. Fundamentalism, on the contrary, is an ideological commitment to the “roots and origins” of religion. Under the aegis of fundamentalism, any religious idea, value or concept has a right to exist. Religious Studies, during the course of time and the production of ever new material, encountered a serious theoretic-methodological problem: How can various religious movements and religious traditions be organized into groups since some of them combine elements of religious modernism and of religious fundamentalism? Already at the end of the nineteen-eighties, the well-established view defining “fundamentalism-modernism” as contrary positions had to be rethought. Studies dating from the nineteen-nineties and the beginning of the new millennium concentrated on noting the social origins and the political character of these phenomena. They demonstrated that neither fundamentalism nor modernism present the whole picture. The lines dividing them are so blurred, that they become confl uent. Consequently, the author concludes that religious fundamentalism and religious modernism are ambivalent phenomena, which can, on occasion, interact with each other.

In biology the idea of matter as something passive has been abandoned in favour of the idea that matter has the capacity of self-activity. In modern physics too, matter functions more as an agent with which the experimenter has a relation than as passive material which he can handle as he likes. So in both fields of study the antithesis between idealism and materialsm has been given up, so that the relation instead of the difference between man and nature became the starting point of scientific inquiry

Comparative Study of the Concept of Space in Aristotle, Descartes and Heidegger

Directory of Open Access Journals (Sweden)

MJ safiyan

2011-09-01

Full Text Available The concept of ''place'' depends on the modern understanding of Being. Today, we regard place simply as a mathematical and measurable space which contains things. Furthermore, we regard this concept as a self-evident concept, while this conception belongs to modern understanding of Being. Since in modern ages Being is understood as an object, place is only measurable space that, in the final analysis, is not separate of the things themselves. But, in the traditional pre-modern thought, for example in Aristotle, since Being means actuality and substance, in accordance to this concept place is the last level of the container of things. Place, for Aristotle, is a natural thing containing natural things but he does not think about it as a mere quantitative thing (as Descartes thinks so. Everything, according to its special nature, has natural place. Soil, water, air and fire, each one has its own special place. Heidegger, who believes that old and modern Metaphysical thought are based on neglecting the Truth of Being, criticizes traditional conception of place and tries to think about it according to the human beings Dasein, nearness and distance to Being and beings.

In this work, integrated process design and control of reactive distillation processes is considered through a computer-aided framework. First, a set of simple design methods for reactive distillation column that are similar in concept to non-reactive distillation design methods are extended...... to design-control of reactive distillation columns. These methods are based on the element concept where the reacting system of compounds is represented as elements. When only two elements are needed to represent the reacting system of more than two compounds, a binary element system is identified....... It is shown that the same design-control principles that apply to a non-reacting binary system of compounds are also valid for a reactive binary system of elements for distillation columns. Application of this framework shows that designing the reactive distillation process at the maximum driving force...

A feasibility study on wavelet transform for reactivity coefficient estimation

International Nuclear Information System (INIS)

Shimazu, Yoichiro

2000-01-01

Recently, a new method using Fourier transform has been introduced in place of the conventional method in order to reduce the time required for the measurement of moderator temperature coefficient in domestic PWRs. The basic concept of these methods is to eliminate noise in the reactivity signal. From this point of view, wavelet analysis is also known as an effective method. In this paper, we tried to apply this method to estimate reactivity coefficients of a nuclear reactor. The basic idea of the reactivity coefficient estimation is to analyze the ratios themselves of the corresponding expansion coefficients of the wavelet transform of the signals of reactivity and the relevant parameter. The concept requires no inverse wavelet transform. Based on numerical simulations, it is found that the method can reasonably estimate reactivity coefficient, for example moderator temperature coefficient, with less length of time sequence data than those required for Fourier transform method. We will continue this study to examine the validity of the estimation procedure for the actual reactor data and further to estimate the other reactivity coefficients. (author)

Hypnosis and modern frontal-lobe concepts--a sketch for a review and an invitation to one particularly promising field.

Science.gov (United States)

Muzur, Amir

2006-03-01

The present paper intends to briefly review the most important concepts of the modern neuropsychology of the frontal lobes, and to relate these findings to the phenomenology usually encountered in hypnosis research and practice. The frontal lobes have been studied very intensively during the last several years and some of the results, including the syndromes described in frontal-lobe lesions and psychiatric patients, demonstrate striking similarity with hypnotic phenomena. Based on these similarities, an alternative neuropsychophysiological definition of hypnosis/suggestion is proposed, viewing hypnosis/suggestion as the process of external manipulation with frontal-lobe functions with consequent effects upon the entire brain potential of the subject.

Modern physics has forever changed the way we view and understand physical reality. With a wide spectrum of theories, from general relativity to quantum mechanics, our conceptions of the very big and the very small are no longer intuitively obvious. Many philosophers, even scientists have expressed the opinion that the counterintuitive conclusions posited in modern physics are best understood using spiritual terminology. In the 11 lectures in this volume, Harav Ginsburgh, one of our generation's foremost scholars, innovators, and teachers of Kabbalah, reveals how modern physics reflects foundational concepts in the Torah's inner dimension. A wide range of topics from relativity (special and general), quantum mechanics, and string theory are addressed.

Kambe, Mitsuru; Tsunoda, Hirokazu; Mishima, Kaichiro; Iwamura, Takamichi

2002-01-01

The 200 kWe uranium-nitride fueled lithium cooled fast reactor concept 'RAPID-L' to achieve highly automated reactor operation has been demonstrated. RAPID-L is designed for Lunar base power system. It is one of the variants of RAPID (Refueling by All Pins Integrated Design), fast reactor concept, which enable quick and simplified refueling. The essential feature of RAPID concept is that the reactor core consists of an integrated fuel assembly instead of conventional fuel subassemblies. In this small size reactor core, 2700 fuel pins are integrated altogether and encased in a fuel cartridge. Refueling is conducted by replacing a fuel cartridge. The reactor can be operated without refueling for up to 10 years. Unique challenges in reactivity control systems design have been attempted in RAPID-L concept. The reactor has no control rod, but involves the following innovative reactivity control systems: Lithium Expansion Modules (LEM) for inherent reactivity feedback, Lithium Injection Modules (LIM) for inherent ultimate shutdown, and Lithium Release Modules (LRM) for automated reactor startup. All these systems adopt lithium-6 as a liquid poison instead of B 4 C rods. In combination with LEMs, LIMs and LRMs, RAPID-L can be operated without operator. This is the first reactor concept ever established in the world. This reactor concept is also applicable to the terrestrial fast reactors. In this paper, RAPID-L reactor concept and its transient characteristics are presented. (authors)

2015-06-01

The First World War produced a huge number of disabled soldiers. During the war, surgeons realized that it was not enough to merely treat the limbs of the wounded soldiers; it was also necessary to train them to use their remaining abilities to their greatest capacity. Governments at the same time realized that such a high number of veterans created a financial burden, by entitling disabled veterans to full healthcare, raising the issues of social welfare. Both in the US and Europe, programs of rehabilitation were instituted, providing injured soldiers with long-term medical care and vocational training aimed at restituting soldier's independence for a speedy return to work. In Italy at the Istituto Ortopedico Rizzoli, one of the most renowned Hospitals for the treatment of orthopedic deformities, Putti set up a technologically advanced Orthopedic Workshop, and a Rehabilitation House. The so called "reconstruction programs" addressed all aspects of rehabilitation (including physiotherapy, curative workshops and vocational therapy), seeing disability in terms of function. The experience gained in the treatment of war victims markedly enriched rehabilitation techniques, but overall the First World War helped engender the concept of rehabilitative programs to assist disabled veterans reintegrate in the workplace, thus laying the foundations of the modern concept of participation at a social level. In the centenary of Italy's entry into the First World War, it is worth underlining just how much hindsight affords us a new perspective on Physical Medicine and Rehabilitation. It reminds us that rehabilitation is not merely the role of medicine, but forms part of a multifaceted approach involving societal roles and expectations, regardless of the psychological and physical impairments suffered by the individuals concerned.

The great disadvantages are specially that can generate this way to see the world, from the environmental point of view and the behavior of the man in this surroundings of modernity is questioned from the ethics. One considers the necessity to carry out a reconstruction of the different typical ethical and pedagogical concepts from modernity and the exigency to create new ones, based on the logics of the complexity, that trigger a new conception of the relation man-nature based on the respect, that it evaluates the old conceptions based on operate resource. Doubtlessly, the present life is developed in urban means, for that reason it is tried to put in context all this exposition within this means, to include/understand of one better way all the threads that are tiled around the city

Rafael Capurro

2009-11-01

Full Text Available This text provides an overview of the complex history of the concept of information in the Greek-Latin as well as in the Medieval and Modern traditions. It connects the Latin etymology of the term informatio with the Greek concepts of eidos/idea and morphé and shows how the objective meaning of information (‘giving form to something’ becomes obsolete in modernity where only the communicational meaning (‘telling something (new to someone’ remains. Information theories in the 20th Century are related to the development of technical systems of message transmission. They give rise to a renaissance of the objective notion of information but under a different framework as the one of the classic pre-modern philosophy. Establishing a connection between the concepts of information and message several options are presented leading to a concept of information based on a theory of messages.

Formation of modern theoretical regulations about organization concerning management development

Directory of Open Access Journals (Sweden)

Zhalinska I.V.

2017-03-01

Full Text Available The article deals with the scientific concepts about an organization as the entity of management concerning management development. The author studies the principal theoretical regulations about an organization within the most spread schools of management and context of development of other managerial concepts in particular, strategic management. It is found out that an organization and its development had not considered as the factor of an effective activity before. Researches paid their attention to single aspects of organization activity where the aspects allowed to increase economic efficiency. However, the objective complication of conditions of enterprises’ activities caused the necessity of scientific research of adequate models of functioning and development of organizations, which currently cannot be provided by traditional management concepts. Thus, theoretical and practical prerequisites arise for a separate scientific set of researches within the science of management such as the theory of an organization. The article describes the main classified approaches to the models of an organization. The paper researches the challenges in present management, and those ones, which have caused the crisis in modern management. It is singled out the following actual aspects of modern organizational processes as the all-round use of modern information and computer systems, the development of integration and in cooperation in management, the appearance of new management technologies, the use of new assessment criteria for organization activity, striving for organizational shifts and innovations. Due to the generalization of the study results, the authors single out such key aspects in the development of the science of management, as the crisis of traditional management influences upon practical activity of modern organizations; the achievements of traditional management schools are becoming necessary, but not determinant factors of organization

Power flattening and reactivity suppression strategies for the Canadian supercritical water reactor concept

International Nuclear Information System (INIS)

McDonald, M.; Colton, A.; Pencer, J.

2015-01-01

The Canadian supercritical water-cooled reactor (SCWR) is a conceptual heavy water moderated, supercritical light water cooled pressure tube reactor. In contrast to current heavy water power reactors, the Canadian SCWR will be a batch fuelled reactor. Associated with batch fuelling is a large beginning-of-cycle excess reactivity. Furthermore, radial power peaking arising as a consequence of batch refuelling must be mitigated in some way. In this paper, burnable neutron absorber (BNA) added to fuel and absorbing rods inserted into the core are considered for reactivity management and power flattening. A combination of approaches appears adequate to reduce the core radial power peaking, while also providing reactivity suppression. (author)

Modern diagnostics of midfacial trauma are embedded in a diagnostic concept that is oriented to the therapeutic relevance for the individual. Critical analysis of the indicated and efficient radiological method in the acute phase shows that MSCT is currently the method of choice in the diagnosis of midfacial trauma. Besides extensive acquisition of data in the shortest time the possibilities of modern post-processing provide a three-dimensional picture of the often complex injuries in real time. Other perilous injuries are often more important especially for the polytrauma patient. With modern scan protocols intracranial injuries as well as injuries of bone and soft tissue of the head and neck region can be diagnosed during a single examination. Radiology plays a key role for the economically oriented strategy of patient care. (orig.)

Between modern and postmodern: problem of the «political identity» concept in the scientific discourse of the 20th century

Directory of Open Access Journals (Sweden)

L. Y. Uhryn

2017-06-01

Full Text Available The sociopolitical and intellectual preconditions of the «political identity» concept’s categorical construction in the 20th century, as well as its historic and political origins have been defined in the article. It has been proved by the author that the «political identity» concept had replaced certain concepts, traditional for the Western classic philosophy discourse, such as «oneness», «selfness» and «self-awareness». Moreover, it was actualized by the cultural and sociopolitical context of late Modern and by the situation of transition from traditional society towards the post-traditional one, which was characterized by the increasing complexity of the social structure and expansion of political participation’s possibilities for citizens and groups. More relevant reflection of the social and communication dimensions of identity were provided, grounded by the psychoanalytical and sociological traditions of its interpretations and were further developed by the representatives of the symbolic interactionism and social constructivism. The conceptualization of the political identity began in the first half of the 20th century within the electoral studies, during which it was equated with party, ideological and class identification. Its broader interpretation was developed within the theories of modernization, transitology, new social movements, social and political systems, which emphasized the institutional and behavioral dimensions of political identity, as well as its integrative functions. It has been established in the study that the division into individual and collective (social identities facilitated the differentiation of the identity research in political and social sphere and its subject identification. As a result, the collective identities most fully integrated into the subject field of political science, as they were interpreted as a reflection of common expectations, goals being as a factor of collective action

Paving the Way Towards Reactive Planar Spanner Construction in Wireless Networks

Science.gov (United States)

Frey, Hannes; Rührup, Stefan

A spanner is a subgraph of a given graph that supports the original graph's shortest path lengths up to a constant factor. Planar spanners and their distributed construction are of particular interest for geographic routing, which is an efficient localized routing scheme for wireless ad hoc and sensor networks. Planarity of the network graph is a key criterion for guaranteed delivery, while the spanner property supports efficiency in terms of path length. We consider the problem of reactive local spanner construction, where a node's local topology is determined on demand. Known message-efficient reactive planarization algorithms do not preserve the spanner property, while reactive spanner constructions with a low message overhead have not been described so far. We introduce the concept of direct planarization which may be an enabler of efficient reactive spanner construction. Given an edge, nodes check for all incident intersecting edges a certain geometric criterion and withdraw the edge if this criterion is not satisfied. We use this concept to derive a generic reactive topology control mechanism and consider two geometric criteria. Simulation results show that direct planarization increases the performance of localized geographic routing by providing shorter paths than existing reactive approaches.

Catalase as a sulfide-sulfur oxido-reductase: An ancient (and modern?) regulator of reactive sulfur species (RSS).

Science.gov (United States)

Olson, Kenneth R; Gao, Yan; DeLeon, Eric R; Arif, Maaz; Arif, Faihaan; Arora, Nitin; Straub, Karl D

2017-08-01

Catalase is well-known as an antioxidant dismutating H 2 O 2 to O 2 and H 2 O. However, catalases evolved when metabolism was largely sulfur-based, long before O 2 and reactive oxygen species (ROS) became abundant, suggesting catalase metabolizes reactive sulfide species (RSS). Here we examine catalase metabolism of H 2 S n , the sulfur analog of H 2 O 2 , hydrogen sulfide (H 2 S) and other sulfur-bearing molecules using H 2 S-specific amperometric electrodes and fluorophores to measure polysulfides (H 2 S n ; SSP4) and ROS (dichlorofluorescein, DCF). Catalase eliminated H 2 S n , but did not anaerobically generate H 2 S, the expected product of dismutation. Instead, catalase concentration- and oxygen-dependently metabolized H 2 S and in so doing acted as a sulfide oxidase with a P 50 of 20mmHg. H 2 O 2 had little effect on catalase-mediated H 2 S metabolism but in the presence of the catalase inhibitor, sodium azide (Az), H 2 O 2 rapidly and efficiently expedited H 2 S metabolism in both normoxia and hypoxia suggesting H 2 O 2 is an effective electron acceptor in this reaction. Unexpectedly, catalase concentration-dependently generated H 2 S from dithiothreitol (DTT) in both normoxia and hypoxia, concomitantly oxidizing H 2 S in the presence of O 2 . H 2 S production from DTT was inhibited by carbon monoxide and augmented by NADPH suggesting that catalase heme-iron is the catalytic site and that NADPH provides reducing equivalents. Catalase also generated H 2 S from garlic oil, diallyltrisulfide, thioredoxin and sulfur dioxide, but not from sulfite, metabisulfite, carbonyl sulfide, cysteine, cystine, glutathione or oxidized glutathione. Oxidase activity was also present in catalase from Aspergillus niger. These results show that catalase can act as either a sulfide oxidase or sulfur reductase and they suggest that these activities likely played a prominent role in sulfur metabolism during evolution and may continue do so in modern cells as well. This also appears

The object of this research is the concept of the festival of street arts on the basis of the gallery "Sweater", which can be used as a practical guide to the implementation of the project, as well as the methodical basis for the development of social and cultural projects, such as festivals. The article reveals the concept of street art not only as a form of painting – graffiti, but the art, born in the streets, and comprising street musicians, singers, actors, photographers and dancers. The concept of the festival, its functions and types have been disclosed, the possibility of the organisation of the festival on the basis of the gallery "Sweater" and organisational content for it have been also analysed. There has been created the concept of the event. All the stages of its organisation and implementation have been examined. Expected results of the "festival of street arts" have been determined, and the prospects for its further development have been outlined.

[The role of imagination in modern medicine].

Science.gov (United States)

Schott, Heinz

2004-06-01

In Renaissance and early modern times, the concept of imagination (Latin imaginatio) was essential for the (natural) philosophical explanation of magic processes, especially in the anthropology of Paracelsus. He assumed that imagination was a natural vital power including cosmic, mental, phychical, and physical dimensions. The Paracelsians criticized traditional humor pathology ignoring their theory of' 'natural magic'. On the other hand, they were criticized by their adversaries as charlatans practicing 'black magic'. About 1800, in between enlightenment and romanticism, the healing concept of, animal magnetism' (Mesmerism) evoked an analogous debate, whether, magnetic' phenomena originated from a real (physical) power (so-called, fluidum') or were just due to fantasy or imagination (German Einbildungskraft). At the end of the 19th century, the French internist Hippolyte Bernheim created-against the background of medical hypnosis (hypnotism') as a consequence of Mesmerism - his theory of suggestion and autosuggestion: a new paradigm of psychological respectively psychosomatic medicine, which became the basis for the concept of, placebo' in modern biomedicine. From now on, all the effects of, alternative medicine' could easily be explained by the, placebo-effect', more or less founded - at least unconsciously - on fraud.

Modern integral equation techniques for quantum reactive scattering theory

Auerbach, S.M.

1993-11-01

Rigorous calculations of cross sections and rate constants for elementary gas phase chemical reactions are performed for comparison with experiment, to ensure that our picture of the chemical reaction is complete. We focus on the H/D+H 2 → H 2 /DH + H reaction, and use the time independent integral equation technique in quantum reactive scattering theory. We examine the sensitivity of H+H 2 state resolved integral cross sections σ v'j',vj (E) for the transitions (v = 0,j = 0) to (v' = 1,j' = 1,3), to the difference between the Liu-Siegbahn-Truhlar-Horowitz (LSTH) and double many body expansion (DMBE) ab initio potential energy surfaces (PES). This sensitivity analysis is performed to determine the origin of a large discrepancy between experimental cross sections with sharply peaked energy dependence and theoretical ones with smooth energy dependence. We find that the LSTH and DMBE PESs give virtually identical cross sections, which lends credence to the theoretical energy dependence

On the co-creation of classical and modern physics.

Science.gov (United States)

Staley, Richard

2005-12-01

While the concept of "classical physics" has long framed our understanding of the environment from which modern physics emerged, it has consistently been read back into a period in which the physicists concerned initially considered their work in quite other terms. This essay explores the shifting currency of the rich cultural image of the classical/ modern divide by tracing empirically different uses of "classical" within the physics community from the 1890s to 1911. A study of fin-de-siècle addresses shows that the earliest general uses of the concept proved controversial. Our present understanding of the term was in large part shaped by its incorporation (in different ways) within the emerging theories of relativity and quantum theory--where the content of "classical" physics was defined by proponents of the new. Studying the diverse ways in which Boltzmann, Larmor, Poincaré, Einstein, Minkowski, and Planck invoked the term "classical" will help clarify the critical relations between physicists' research programs and their use of worldview arguments in fashioning modern physics.

[Citizenship and modernity: the emergence of the social issue on the public agenda

Science.gov (United States)

Bodstein

1997-04-01

The guiding thread of this article is the inclusion of the so-called "social issue" on the public agenda from modernity through its more current developments. The study seeks to demonstrate that one of the meanings of modernity is precisely the radical inversion of the meaning of public and private, providing for the broadening of public space. Far from being associated with a given bourgeois capitalist model, modernity thus projects itself as a reinvention of rights, citizenship, and contemporary democratic experience. Over this long course, the individualization process has been seen as a crucial factor for understanding both the ideology of modern societies and - paradoxically - the very emergence of social sciences. The individualist concept, emphasizing the specificity of modern representation of the social sphere, i.e., its characteristic as a self-instituting society, allows for a broadened understanding of the public domain. In this sense, the ideological polarization between liberal conceptions (favoring individualism) and Marxist ones (linked to holistic representations of the social sphere) should be reviewed, since this polarization has repercussions on the very analytical tools used by social sciences.

Reactivation or reinfection in adult tuberculosis: Is that the question?

Science.gov (United States)

Cardona, Pere-Joan

2016-12-01

Looking at the chapter on "natural history" in any tuberculosis (TB) reference book, there is a kind of certainty regarding TB in adults. That is the concept of "post-primary" TB described as the reactivation of dormant bacilli hidden in an old lesion developed during infancy due to a type of local immunosuppression. Intriguingly, this concept involves at least two major uncertainties: how can dormant bacilli remain for such a long period, almost a lifetime, in an old lesion, taking into account granuloma dynamism; and what sort of local immunosuppression is the one that facilitates reactivation? The controversy between reactivation and exogenous reinfection as the cause of active TB started very soon in TB research. Interestingly, this "balance" was disturbed in the 1960s when the "Unitary Concept" became very successful in supporting the reactivation dogma. The "Unitary Concept" was mainly based on the data of tuberculin surveillance during the pre-antibiotic era as well as the data obtained from experimental modelling in animals. At the same time, the "Three-risks model" appeared to explain the relationship between the risk of infection and TB incidence, granting reinfection a key role in adult TB together with primary infection. This role was reinforced by the studies of recurrence based on molecular epidemiology, and a better knowledge of the immune response, granuloma dynamics, and lung physiology. Now it is a matter of taking it into account when designing new prophylactic and therapeutic strategies and also reflecting it in text books to better illustrate to our students.

Upgrading the Reactor Power Control Concept with a Modern Digital Control System

International Nuclear Information System (INIS)

Laengle, M.; Schildheuer, R.

2011-01-01

Within the framework of a retrofit project, a reactor power instrumentation and control system (REALL) - consisting of a limiting system and the respective reactor control systems - was retrofitted and modernized in a 1450-MW-nuclear-power-plant in Baden-Wuerttemberg. The REALL process control functions were implemented within a modern and completely digitized control system that has been designed for use in safety I and C applications. Along with the installation of the digital control system, the associated hardware was adapted to today's state of the art. At the same time, the given potential for improvement, as revealed during the plant's operation so far, was taken into account in the programming. In order to provide for transparent and quality-assured project management, the implementation was based on a stage plan consisting of several steps, along with specific milestones. Final commissioning of the modern digital control system took place during the 2008 plant overhaul. Despite the complex commissioning procedure, it was possible to avoid a major prolongation of the plant's downtime and to keep within a rough 4-week timeframe that had originally been defined for the plant overhaul to adequate structuring of the project, goal-oriented implementation of preparatory infrastructural measures and adequate scheduling of the coordinated activities of the installation and commissioning teams entrusted with the commissioning of the digital control system during the overhaul activities.

Rethinking critical reflection on care: late modern uncertainty and the implications for care ethics.

Science.gov (United States)

Vosman, Frans; Niemeijer, Alistair

2017-12-01

Care ethics as initiated by Gilligan, Held, Tronto and others (in the nineteen eighties and nineties) has from its onset been critical towards ethical concepts established in modernity, like 'autonomy', alternatively proposing to think from within relationships and to pay attention to power. In this article the question is raised whether renewal in this same critical vein is necessary and possible as late modern circumstances require rethinking the care ethical inquiry. Two late modern realities that invite to rethink care ethics are complexity and precariousness. Late modern organizations, like the general hospital, codetermined by various (control-, information-, safety-, accountability-) systems are characterized by complexity and the need for complexity reduction, both permeating care practices. By means of a heuristic use of the concept of precariousness, taken as the installment of uncertainty, it is shown that relations and power in late modern care organizations have changed, precluding the use of a straightforward domination idea of power. In the final section a proposition is made how to rethink the care ethical inquiry in order to take late modern circumstances into account: inquiry should always be related to the concerns of people and practitioners from within care practices.

In the Factory of Modernity: Capital, State, Empire.

Directory of Open Access Journals (Sweden)

Sandro Mezzadra

2016-12-01

Full Text Available The essay tackles the intertwining of State and capital as powers that dominate modernity, locating on a global scale right from the start. This intertwining intersects inevitably the history of empire, which, rather than just being the precedent of the State, represents a composite form of layered sovereignties and multifaceted juridical spaces. The concept of the State that emerges from the essay moves away from the broadly meant Weberian conception, which is prevailing in contemporary literature. In contrast with the Weberian definition, indeed, the territoriality of the State is unsettled and altered both by the swaying of its borders and by the emergence of new territorial formations inside and across the borders. The global view on the State complicates its relationship with the nation and the idea of the monopoly of the legislative production and legitimate physical strength. The result is a much more fragmented and movable image of the history of modern State.

A review of post-modern management techniques as currently applied to Turkish forestry.

Dölarslan, Emre Sahin

2009-01-01

This paper reviews the effects of six post-modern management concepts as applied to Turkish forestry. Up to now, Turkish forestry has been constrained, both in terms of its operations and internal organization, by a highly bureaucratic system. The application of new thinking in forestry management, however, has recently resulted in new organizational and production concepts that promise to address problems specific to this Turkish industry and bring about positive changes. This paper will elucidate these specific issues and demonstrate how post-modern management thinking is influencing the administration and operational capacity of Turkish forestry within its current structure.

Plant dynamics analyses of fast reactor concept: RAPID-A without any control rod

International Nuclear Information System (INIS)

Kambe, Mitsuru

1996-01-01

Plant dynamics analyses of a fast reactor concept RAPID-A without any control rod have been demonstrated in case of reactor startup and sudden change of the primary flow rate. RAIP-A concept involves Lithium Expansion Module (LEM) for inherent reactivity feedback, Lithium Injection Module (LIM) for inherent ultimate shutdown and Lithium Release Module (LRM) for automated reactor startup. LEM consists of Quick-LEM and Slow-LEM. Slow-LEM provides with moderate reactivity addition as decreasing temperature. Quick-LEM assures quick negative reactivity feedback as increasing temperature. Plant dynamics analyses revealed that reactor power is nearly proportional to the primary flow rate even if the flow rate increases suddenly. Fully automated reactor startup from the subcritical condition has been attempted by inserting reactivity at a constant rate by LRM. Allowable rate of reactivity addition has been obtained in respect to Quick-LEM reactivity worth. (author)

Rapid-L Operator-Free Fast Reactor Concept Without Any Control Rods

International Nuclear Information System (INIS)

Kambe, Mitsuru; Tsunoda, Hirokazu; Mishima, Kaichiro; Iwamura, Takamichi

2003-01-01

The 200-kW(electric) uranium-nitride-fueled lithium-cooled fast reactor concept 'RAPID-L' to achieve highly automated reactor operation has been demonstrated. RAPID-L is designed for a lunar base power system. It is one of the variants of the RAPID (Refueling by All Pins Integrated Design) fast reactor concept, which enables quick and simplified refueling. The essential feature of the RAPID concept is that the reactor core consists of an integrated fuel assembly instead of conventional fuel subassemblies. In this small-size reactor core, 2700 fuel pins are integrated and encased in a fuel cartridge. Refueling is conducted by replacing a fuel cartridge. The reactor can be operated without refueling for up to 10 yr.Unique challenges in reactivity control systems design have been addressed in the RAPID-L concept. The reactor has no control rod but involves the following innovative reactivity control systems: lithium expansion modules (LEM) for inherent reactivity feedback, lithium injection modules (LIM) for inherent ultimate shutdown, and lithium release modules (LRM) for automated reactor startup. All these systems adopt 6 Li as a liquid poison instead of B 4 C rods. In combination with LEMs, LIMs, and LRMs, RAPID-L can be operated without an operator. This reactor concept is also applicable to the terrestrial fast reactors. In this paper, the RAPID-L reactor concept and its transient characteristics are presented

Economic-environmental active and reactive power scheduling of modern distribution systems in presence of wind generations: A distribution market-based approach

International Nuclear Information System (INIS)

Samimi, Abouzar; Kazemi, Ahad; Siano, Pierluigi

2015-01-01

Highlights: • A new market-based approach is proposed to schedule active and reactive powers. • Multi-component reactive power bidding structures for DERs is introduced. • A new economical/environmental operational scheduling method is proposed. • At distribution level, a reactive power market is developed in presence of DERs. - Abstract: Distribution System Operator (DSO) is responsible for active and reactive power scheduling in a distribution system. DSO purchases its active and reactive power requirements from Distributed Energy Resources (DERs) as well as the wholesale electricity market. In this paper, a new economical/environmental operational scheduling method based on sequential day-ahead active and reactive power markets at distribution level is proposed to dispatch active and reactive powers in distribution systems with high penetration of DERs. In the proposed model, after day-ahead active power market was cleared the participants submit their reactive power bids and then the reactive power market will be settled. At distribution level, developing a Var market, in which DERs like synchronous machine-based Distributed Generation (DG) units and Wind Turbines (WTs) could offer their reactive power prices, DERs are motivated to actively participate in the Volt/VAr Control (VVC) problem. To achieve this purpose, based on the capability curves of considered DERs, innovative multi-component reactive power bidding structures for DERs are introduced. Moreover, the effect of reactive power market clearing on the active power scheduling is explicitly considered into the proposed model by rescheduling of active power by usage of energy-balance service bids. On the other hand, environmental concerns that arise from the operation of fossil fuel fired electric generators are included in the proposed model by employing CO_2 emission penalty cost. The suggested reactive power market is cleared through a mixed-integer nonlinear optimization program. The

Imagining 'reactivity': allergy within the history of immunology.

Science.gov (United States)

Jamieson, Michelle

2010-12-01

An allergy is commonly understood to be an overreaction of the immune system to harmless substances that are misrecognised as foreign. This concept of allergy as an abnormal, misdirected immune response-a biological fault-stems from the idea that the immune system is an inherently defensive operation designed to protect the individual through an innate capacity to discriminate between the benign and toxic, or self and nonself. However, this definition of allergy represents a radical departure from its original formulation. Literally meaning 'altered reactivity', the term was coined in 1906 by Austrian paediatrician Clemens von Pirquet, to describe the fundamentally mutable nature of the immune response. This paper argues that the conventional interpretation of allergy-as-pathology derives from specific concepts of 'organism', 'response', and 'normal' immune function that have-for over a century-governed the perception and study of immune phenomena within immunology. Through an examination of Louis Pasteur's conceptualisation of the host body/microorganism relationship, I argue that immunology is founded on a view of the organism as a discrete, autonomous entity, and on a concomitant notion of the immune response as essentially reactive. Revisiting the concept of 'altered reactivity', this paper points to the fact that allergy was initially posited as a general theory of immune responsiveness and, importantly, one that poses a significant challenge to orthodox notions of immunopathology. It suggests that Pirquet's unique view of immune responsiveness presents an account of organismic or biological identity that encapsulates, rather than reduces, its ecological complexity.

CERN Document Server

Anderson, Brian D O

2006-01-01

Geared toward upper-level undergraduates and graduate students, this book offers a comprehensive look at linear network analysis and synthesis. It explores state-space synthesis as well as analysis, employing modern systems theory to unite the classical concepts of network theory. The authors stress passive networks but include material on active networks. They avoid topology in dealing with analysis problems and discuss computational techniques. The concepts of controllability, observability, and degree are emphasized in reviewing the state-variable description of linear systems. Explorations

Sub-fragmentation of structural-reactive-material casings under explosion

Science.gov (United States)

Zhang, Fan

2015-06-01

The sub-fragmentation of structural reactive material (SRM) thick-casings is to generate fine fragments during casing fragmentation under explosive loading for their efficient energy release to enhance air blast. This has been investigated using a cylindrical casing made from either rich Al-MoO3 or Al-W-based granular composites. The former composite was to study the concept of reactive hot spots where the reaction of reactive particles, which were distributed into base SRM in a fuel-rich equivalence ratio, created heat and gas products during SRM fragmentation. The expansion of these distributed hot spots initiated local fractures of the casing, leading to fine fragments. The Al-W-based composite investigated the concept of impedance mismatch, where shock dynamics at the interfaces of different impedance ingredients resulted in non-uniform, high local temperatures and stresses and late in times the dissimilar inertia resulted in different accelerations, leading to material separation and fine fragments. The casings were manufactured through both hot iso-static pressing and cold gas dynamic spray deposition. Explosion experiments were conducted in a 3 m diameter, 23 m3 cylindrical chamber for these cased charges in a casing-to-explosive mass ratio of 1.75. The results demonstrated the presence of fine fragments and more efficient fragment combustion, compared with previous results, and indicated the effectiveness of both concepts. This work was jointly funded by Defence R&D Canada and the Advanced Energetics Program of DTRA (Dr. William H. Wilson).

The ideology of moderated modernism in Serbian music and musicology

Medić Ivana

2007-01-01

Full Text Available The term ′moderated modernism′ has been current for quite some time in Serbian music historiography, but there have been only a few attempts to define it. I shall try to define the term, introduce some of its key concepts and features and demonstrate its applicability. Although moderated modernism was an international phenomenon which had divergent manifestations in various periods before and after the Second World War throughout Europe, my aim is to focus on the period between the decline of Socialist Realism and the ascent of post-modernism (roughly 1950 to 1980 in socialist Serbia, and to discuss the discourses and ideologies surrounding moderated modernism then and there.

Nomadic concepts in the history of biology.

Surman, Jan; Stráner, Katalin; Haslinger, Peter

2014-12-01

The history of scientific concepts has firmly settled among the instruments of historical inquiry. In our section we approach concepts from the perspective of nomadic concepts (Isabelle Stengers). Instead of following the evolution of concepts within one disciplinary network, we see them as subject to constant reification and change while crossing and turning across disciplines and non-scientific domains. This introduction argues that understanding modern biology is not possible without taking into account the constant transfers and translations that affected concepts. We argue that this approach does not only engage with nomadism between disciplines and non-scientific domains, but reflects on and involves the metaphoric value of concepts as well.

Nonequilibrium statistical physics a modern perspective

CERN Document Server

Livi, Roberto

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.

Full Text Available The aim of this work describes the strong influence the development of the management theory to the complex nature of modern marketing concept and intellectual capital. Often, in the contemporary conversation we hear the word organizational behavior that is closely related to the concept of modern business philosophy and importance of human capital. Sudden development of human thought in the beginning of the twentieth century has a great impact on all areas of social life, and specially on the promotion of all areas of business and the impact of the application of marketing, its development and implementation as a basis for achieving global competitiveness. Changes caused by the development of management in the business have led to the interactive relationship between organizations and consumers, but also to the development of relations within the organization between employees. .

Border or Horizon? Comparing the concept of "reason" in the liberal and republican traditions

Rafael Mesquita

2015-12-01

Full Text Available The current article analyzes the expectations of modernity's political philosophy, in its liberal and republican traditions, towards reason: its conceptualization, prerogatives and normative implications. In order to do so, we highlight the role of this human faculty in the theses of seminal authors of modernity and its conjugation the concepts of liberty and equality. Taking social contract theory for a starting point, we contrast the concept of reason in liberalism and republicanism, and after we analyze the implications of the social features of modern democracy (massive and egalitarian for the concept of the rational individual. In conclusion, it is argued that though reason is presented as the cornerstone of the political individual in modernity, locus of human autonomy and justification for its isonomy, its conceptualization varies according to the political tradition, with consequences for the legitimate limits of State action upon the citizen and for the expectations of moral progress of the population.

Fast Flux Test Facility (FFTF) feedback reactivity components

International Nuclear Information System (INIS)

Nguyen, D.H.

1988-04-01

The static tests conducted during Cycle 8A (1986) of the FFTF have allowed, for the first time, the experimental determination of each of the feedback reactivities caused by the following mechanisms: fuel axial expansion, control rod repositioning, core radial expansion, and subassembly bowing. A semiempirical equation was obtained to describe each of these feedback components that depended only on the relevant reactor temperature (bowing was presented in a tabular form). The Doppler and sodium density reactivities were calculated using existing mechanistic methods. Although they could also be fitted with closed-form equations depending only on temperatures, these equations are not needed in transient analyses using whole core safety computer codes, which use mechanistic methods. The static feedback reactivity model was extended to obtain a dynamic model via the concept of ''time constants.'' Besides being used for transient analyses in the FFTF, these feedback equations constitute a database for the validation and/or calibration of mechanistic feedback reactivity models. 2 refs., 6 tabs

Zajaczek, J.E.W.; Rodt, T.; Keberle, M.

2007-01-01

Modern diagnostics of midfacial trauma are embedded in a diagnostic concept that is oriented to the therapeutic relevance for the individual. Critical analysis of the indicated and efficient radiological method in the acute phase shows that MSCT is currently the method of choice in the diagnosis of midfacial trauma. Besides extensive acquisition of data in the shortest time the possibilities of modern post-processing provide a three-dimensional picture of the often complex injuries in real time. Other perilous injuries are often more important especially for the polytrauma patient. With modern scan protocols intracranial injuries as well as injuries of bone and soft tissue of the head and neck region can be diagnosed during a single examination. Radiology plays a key role for the economically oriented strategy of patient care. (orig.)

Multichannel strategy - the dominant approach in modern retailing

Directory of Open Access Journals (Sweden)

Stojković Dragan

2016-01-01

Full Text Available The purpose of this paper is to thoroughly analyse the concept of multichannel strategy, focussing on retail, to enable the academic community and marketers to better understand its advantages and disadvantages. This paper presents a comprehensive literature review and financial data analysis. The authors have analysed the financial data of 88 retail companies in the 2007 to 2014 period, and have proven that the importance of multichannel strategy has grown with the emergence of e-commerce. The main hypothesis is that the multichannel concept dominates modern marketing channels because it is widely accepted and provides superior financial performance. Multichannel retailing is definitely a winning concept, if adequately implemented. However, wrongly implemented it can negatively influence business performance.

An approach of SFR safety study through the most penalizing sodium void reactivity - 105

International Nuclear Information System (INIS)

Tiberi, V.; Ivanov, E.; Pignet, S.

2010-01-01

Sodium void reactivity effects can affect the plant safety significantly during accidental transients. Accordingly, they have to be accurately investigated for any new sodium cooled fast reactor concept, even if a fuel with a melting point lower than the sodium boiling temperature is adopted. Thus all new reactor concepts should be compared to each - others adopting the value of the maximal possible sodium void reactivity as a discrimination parameter. However, taking into account that the sodium void worth is spatially depended, it is not evident which volume could be voided in order to obtain the maximal reactivity increase. Typically the complete active core voiding (zones initially loaded with 235 U or 239 Pu) is taken into account. This paper summarizes the extensive work carried-out in the IRSN to investigate the sodium-void reactivity spatial profiles of a fast sodium-cooled reactor core in the aim of defining a methodology to search for the area where the void contribution to the reactivity is strictly positive. Perturbation theory design approach available in the ERANOS 2.1 code has been adopted to evaluate the 'area of positive void worth'. To do that, the code has been previously validated against experimental based benchmarks (IRPhEP) and reference calculations. The evaluation of the absolute values of reactivity profiles can be improved later-on adopting more sophisticated methodologies to perform more accurate calculations of the sample with the voided area determined adopting the rough procedure described here. It has been demonstrated that even the non-reference way of ERANOS calculations could be used to provide the basis for different core concepts inter-comparison. (authors)

Religions without God? Hans Kelsen, Anthropologist of Modernity

Paolo Di Lucia

2015-11-01

Full Text Available In 2012 an unpublished book by the Austrian legal philosopher Hans Kelsen, Secular Religion, has been posthumously published. This book, written by Kelsen between 1952 and 1964 in the United States, severely criticizes those theories of politics and culture that misinterpret modern social philosophy, science and politics as new religions, mainly adopting the controversial concept of “secular religión.” In the first part of the paper, we reconstruct the genesis of the book and the complex events that led to its final version, and we underline the motives that led Kelsen to write this vehement polemic in defense of the spirit of modernity, and eventually to withdraw it. In the second part of the paper, we investigate some of the main methodological and theoretical contributions that this work, albeit its critical tenor, is able to give to an anthropology of modernity.

Immune reactivities against gums.

Science.gov (United States)

Vojdani, Aristo; Vojdani, Charlene

2015-01-01

Different kinds of gums from various sources enjoy an extremely broad range of commercial and industrial use, from food and pharmaceuticals to printing and adhesives. Although generally recognized as safe by the US Food and Drug Administration (FDA), gums have a history of association with sensitive or allergic reactions. In addition, studies have shown that gums have a structural, molecular similarity to a number of common foods. A possibility exists for cross-reactivity. Due to the widespread use of gums in almost every aspect of modern life, the overall goal of the current investigation was to determine the degree of immune reactivity to various gum antigens in the sera of individuals representing the general population. The study was a randomized, controlled trial. 288 sera purchased from a commercial source. The sera was screened for immunoglobulin G (IgG) and immunoglobulin E (IgE) antibodies against extracts of mastic gum, carrageenan, xantham gum, guar gum, gum tragacanth, locust bean gum, and β-glucan, using indirect enzyme-linked immunosorbent assay (ELISA) testing. For each gum antigen, inhibition testing was performed on the 4 sera that showed the highest IgG and IgE immune reactivity against the different gums used in the study. Inhibition testing on these same sera for sesame albumin, lentil, corn, rice, pineapple, peanut, pea protein, shrimp, or kidney bean was used to determine the cross-reactivity of these foods with the gum. Of the 288 samples, 4.2%-27% of the specimens showed a significant elevation in IgG antibodies against various gums. Only 4 of 288, or 1.4%, showed a simultaneous elevation of the IgG antibody against all 7 gum extracts. For the IgE antibody, 15.6%-29.1% of the specimens showed an elevation against the various gums. A significant percentage of the specimens, 12.8%, simultaneously produced IgE antibodies against all 7 tested extracts. Overall, the percentage of elevation in IgE antibodies against different gum extracts, with

Full Text Available The objective of this paper was to show the historical perspective of the „long centric" occlusal concept and its importance in the modern dentistry, especially from the gnathological aspect. The „long centric" concept represents therapeutic modality used in modern dentistry and occlusal adjustment in all patients showing differences in strong and weak closure of the lower jaw starting from the position of physiological rest/long centric" concept is applied only for anterior teeth and occlusal movements from rather than toward the center. Whenever the „long centric" parameters are not adequate, occlusal disturbance, resulting from the „wedge" effect during the initial closure of the lower jaw, is present. Different degrees of abrasion or hypermobility of the teeth are often the result of the above-mentioned occlusal disturbances and can potentially trigger bruxism and malfunction. Modus procedendi should be the regular approach of every dentist to any occlusion, because only the built-in „long centric" efficiently contributes to the occlusal stability of the anterior portion of the dentition. All occlusions should be routinely tested regarding their need for „long centric", especially when the extensive therapeutic interventions (conservative, prosthetics of the occlusal complex are required.

STAFF MARKETING IN MODERN RUSSIAN CONDITIONS

Directory of Open Access Journals (Sweden)

Nataliya N. Kretova

2017-09-01

Full Text Available The conception of staff marketing, which was developed abroad, is effectively used in the developed countries for a long time. Its main advantage consists in the possibility of organizing some planning for the implementation of staff strategy: staff marketing provides the enterprise on the long-term basis with human resources capable of forming strategic potential, which would allow to implement the planned activities. Numerous problems of formation and development of civilized market relations in our country do not allow to fully implement the detailed models of staff marketing in domestic realities. On the basis of the analysis of theoretical developments and factors that have a practical impact on the implementation of marketing personnel in modern Russian conditions, the authors describe the essential elements of the conception. The primary purposes of staff marketing for domestic enterprises, grouped into the internal and external marketing are substantiated and disclosed. The special attention is paid to increasing the staff loyalty, which has dominant influence on business outcomes. The algorithm of events for the development of motivation system is proposed; at the stage of studying job satisfaction it is recommend to apply analytical calculations with the use of Shewhart control charts. Unlike traditional statistical tools based on the inspection of already implemented results, this approach is aimed at preventing negative tendencies and avoids losses associated with dissatisfaction with difficulty, as the individual employee and the team as a whole. Modern Russian enterprises can fully realize the conception of staff marketing only through rethinking of the consequences for all directions of work with the staff, as reflected in the definition of objectives, motivating staff and ensuring social responsibility of the enterprise.

Guide to mathematical concepts of quantum theory

2008-01-01

Quantum Theory is one of the pillars of modern science developed over the last hundred years. In this review we introduce, step by step, the quantum theory understood as a mathematical model describing quantum experiments. We start with splitting the experiment into two parts: a preparation process and a measurement process leading to a registration of a particular outcome. These two ingredients of the experiment are represented by states and effects, respectively. Further, the whole picture of quantum measurement will be developed and concepts of observables, instruments and measurement models representing the three different descriptions on experiments will be introduced. In the second stage, we enrich the model of the experiment by introducing the concept of quantum channel describing the system changes between preparations and measurements. At the very end we review the elementary properties of quantum entanglement. The text contains many examples and exercise covering also many topics from quantum information theory and quantum measurement theory. The goal is to give a mathematically clear and self-containing explanation of the main concepts of the modern language of quantum theory (Authors)

Health politics meets post-modernism: its meaning and implications for community health organizing.

Science.gov (United States)

Rosenau, P V

1994-01-01

In this article, post-modern theory is described and applied to health politics with examples from community health organizing, social movements, and health promotion. Post-modernism questions conventional assumptions about concepts such as representation, participation, empowerment, community, identity, causality, accountability, responsibility, authority, and roles in community health promotion (those of expert, leader, and organizer). I compare post-modern social movements with their modern counterparts: the organizational forms, leadership styles, and substantive intellectual orientations of the two differ.

Finally, and most importantly, I present the implicit lessons that post-modernism offers to health politics and outline the strengths and weaknesses of this approach to health politics.

Function-related Secondary User Needs and Secondary Data? A Critical Examination of Some Central Concepts in the Modern Theory of Lexicographical Functions

Abstract: The aim of this article is to contribute to the development of the modern theory of lexi-cographical functions by offering a critical examination of the following concepts associated with it: primary needs, primary data, secondary needs, secondary data, function-related needs, and function-related data. By way of introduction, a presentation of the basic tenets of the theory is offered, followed by a description of the gen-eral characteristics of secondary needs and data. Next, on the basis of both a critical analysis of the theory and an examination of selected data types in existing lexicographical products, it is argued that all user needs and all data that satisfy those needs are function-related. The distinction between the concepts function-related and usage-related is thus rejected. Since this has serious implications for the relation between secondary needs and data on the one hand and primary needs and data on the other, this relation is subsequently reconsid-ered. This leads to a redefinition of all the concepts examined. It is also explained why an ideal state of lexico-graphy, where secondary needs and data do not exist, cannot be achieved in the real world.

Keywords: DICTIONARY, LEXICOGRAPHY, LEXICOGRAPHICAL FUNCTION, PRIMARY NEED, PRIMARY DATA, SECONDARY NEED, SECONDARY DATA, FUNCTION-RELATED NEED, FUNCTION-RELATED DATA, EXTRA-LEXICOGRAPHICAL SITUATION, INTRA-LEXICOGRAPHICAL SITUATION, COMMUNICATIVE FUNCTION, COGNITIVE FUNCTION, OPERATIVE FUNCTION, TEXT RECEPTION, TEXT PRODUCTION, TRANSLATION

Voltage on the North American bulk system is normally regulated by synchronous generators, which typically are provided with voltage schedules by transmission system operators. In the past, variable generation plants were considered very small relative to conventional generating units, and were characteristically either induction generator (wind) or line-commutated inverters (photovoltaic) that have no inherent voltage regulation capability. However, the growing level of penetration of non-traditional renewable generation - especially wind and solar - has led to the need for renewable generation to contribute more significantly to power system voltage control and reactive power capacity. Modern wind-turbine generators, and increasingly PV inverters as well, have considerable dynamic reactive power capability, which can be further enhanced with other reactive support equipment at the plant level to meet interconnection requirements. This report contains a set of recommendations to the North-America Electricity Reliability Corporation (NERC) as part of Task 1-3 (interconnection requirements) of the Integration of Variable Generation Task Force (IVGTF) work plan. The report discusses reactive capability of different generator technologies, reviews existing reactive power standards, and provides specific recommendations to improve existing interconnection standards.

Reactivity and neutron emission measurements of highly burnt PWR fuel rod samples

Fuel rods with burnup values beyond 50 GWd/t are characterised by relatively large amounts of fission products and a high abundance of major and minor actinides. Of particular interest is the change in the reactivity of the fuel as a function of burnup and the capability of modern codes to predict this change. In addition, the neutron emission from burnt fuel has important implications for the design of transport and storage facilities. Measurements have been made of the reactivity effects and the neutron emission rates of highly burnt uranium oxide and mixed oxide fuel rod samples coming from a pressurised water reactor (PWR). The reactivity measurements have been made in a PWR lattice in the PROTEUS zero-energy reactor moderated in turn with: water, a water and heavy water mixture and water containing boron. A combined transport flask and sample changer was used to insert the 400 mm long burnt fuel rod segments into the reactor. Both control rod compensation and reactor period methods were used to determine the reactivities of the samples. For the range of burnup values investigated, an interesting exponential relationship has been found between the neutron emission rate and the measured reactivity

The concept of intelligibility in modern physics (1948).

Science.gov (United States)

Feyerabend, Paul K

2016-06-01

This is an English translation of Paul Feyerabend's earliest extant essay "Der Begriff der Verständlichkeit in der modernen Physik" (1948). In it, Feyerabend defends positivism as a progressive framework for scientific research in certain stages of scientific development. He argues that in physics visualizability (Anschaulichkeit) and intelligibility (Verständlichkeit) are time-conditioned concepts: what is deemed visualizable in the development of physical theories is relative to a specific historical context and changes over time. He concludes that from time to time the abandonment of visualizability is crucial for progress in physics, as it is conducive to major theory change, illustrating the point on the basis of advances in atomic theory.

A novel concept of QUADRISO particles Part I: Transmutation of Neptunium and Plutonium

In quadruple isotropic (QUADRISO) coated particles, a burnable absorber layer surrounds the fuel kernel; consequently, during irradiation, the poison depletion allows more neutrons to stream into the kernel and to produce more fission reactions that attenuate the reactivity loss due to fuel depletion. In our previous studies, we have proposed for the first time the novel concept of QUADRISO particles for managing the long term excess of reactivity and we have shown in details how the new concept flattens the reactivity curve as function of time compared to traditional designs of burnable absorbers. In the present study, we apply the new concept of QUADRISO particles for transmuting Light Water Reactors waste in a prismatic high temperature reactor. We simulated two irradiation periods of 500 and 200 days that allow to transmute over 95% and 52% of {sup 239}Pu and actinides, respectively, without any reprocessing of the irradiated fuel in-between. During the first irradiation period the high initial excess of reactivity is managed by the QUADRISO particles; during the second irradiation period, there is no need of QUADRISO particles because of the small initial fissile inventory in the core.

SCWR Concept in Korea

Energy Technology Data Exchange (ETDEWEB)

NONE

2014-08-15

One of the major difficulties in the design of an SCWR is the additional neutron moderation in order to compensate the low coolant density in the later stage of coolant heat-up. The water rod concept was introduced as a simple method to provide additional moderation, however it may result in an inevitable complexity in the design of the reactor upper part. A solid moderator concept was introduced in the Korean SCWR to avoid this difficulty. A conceptual design of a 1400 MWe SCWR core with a cruciform type of U/ZrH{sub 2} solid moderator has been studied. The design features include a solid moderator design, an axial zoning of the burnable poison and fuel rod, a flow rate control by adjusting the orifice design, and a control rod design for an excess reactivity control. The maximum power peaking is 2.48 and the maximum coolant temperature is 577°C. Reactivity coefficients such as the moderator temperature coefficient and fuel temperature coefficient are negative for the whole burn-up period. At a cold zero power condition, the minimum shutdown margin is 1.16%Δρ at the beginning of a cycle, which satisfies the required shutdown margin limit. The concept described here should not be considered as a complete one, but a preliminary idea. It is solely based on information frozen at the time, and is subject to further improvement.

The Expressive Turn of Citizenship in Digital Late Modernity

Jakob Svensson

2011-03-01

Full Text Available The purpose of this paper is to connect the idea of expressive rationality to current debates on citizenship and political participation online. Socializing, cultural consumption/ production, identity management, information and publication strategies are both different and accentuated in digital, networked and late modern environments. In the paper I argue that the kind of network sociability that is emerging today favours an expressive form of rationality. I also claim that expressive rationality transcends the bipolar instrumental – communicative dimension that has been so important for normative theorizing in Political (and Social Sciences and hence is a more rewarding theoretical concept for understanding political participation in digital late modernity.

Miniature thermal matches: from nanoheaters to reactive fractals

Rebholz, Claus; Gunduz, Ibrahim Emre; Ando, Teiichi; Doumanidis, Charalabos C

Fine thermal actuation by miniature heat sources enables applications from electronics fabrication to tumor cauterization. This paper introduces the concept of nanoheaters, i.e., reactive bimetallic material dots (0D), ignited electrically to exothermically release precise heat amounts where and when needed. This concept is extended to nanoheater wires (1D) and foils (2D), as well as bulk nanoheaters (3D) manufactured via ball milling and ultrasonic consolidation of nickel and aluminum powders. The fractal structure of such powders and consolidates, with self-similar, multiscale Apollonian or lamellar packaging, is discovered to hold the key for their ignition sensitivity: nanoscale structures ignite first, to produce enough heat and raise the temperature of submicron formations, which then ignite microscale regions and so on; while inert areas quench and arrest the self-propagating exothermic reaction. Therefore, such engineered fractal reactive heaters lend themselves to affordable, high-throughput manufacture and controllable, safe, efficient, supplyless in situ thermal release. This can be transformative for innovations from self-healing composites and self-heating packages to underwater construction and mining. (paper)

The X-HPD—A modern implementation of a SMART concept

2009-01-01

The concept of hybrid photodetectors which combine a large area photocathode with a crystal scintillator anode in the centre of a hemispherical vacuum tube was demonstrated first with the Philips SMART tubes and, more recently, with the QUASAR tubes of the Lake Baikal experiment. Photoelectrons from the cathode are accelerated by a potential difference of 20–30 kV and deposit their kinetic energy in the scintillator (or Phosphor). The generated scintillation light is detected by a small and low cost photodetector, e.g. a conventional PMT. The X-HPD study is a variation of this concept aiming at improved performance and maximum simplicity. The glass envelope is essentially spherical and a spatial scintillator crystal is mounted in its centre. The spherical symmetry leads to a uniform collection efficiency and very small intrinsic time spread over the full viewing angle of 120° (3π solid angle).

Full Text Available In the work of Immanuel Wallerstein the concepts of modern world-system and capitalist world-economy are used interchangeably; they are alternative names for the historical system we are currently living in. In the substance of his work, however, Wallerstein has been more concerned with capitalism than modernity. At one level this is unimportant because, if they are indeed ‘two sides of the same coin,’ understanding one must enhance inevitably our knowledge of the other. But, of course, it is never as simple asthat. When we choose to think of our contemporary world as either capitalist or modern, we take on board a different social theoretical baggage. It was this train of thought which led me to ask “what’s modern about the modern world-system?” (Taylor, 1996a and this essay is part of a continuing project (Taylor, 1996b; 1999 to link Wallerstein’s (1984: chapter 3 ‘institutional vortex’ to Marshall Berman’s (1982: Introduction ‘modern maelstrom.’

CRITERIA OF TRUTHFULNESS AND THE SCIENTIFIC QUALITY IN POST-MODERN KNOWLEDGE

Olga Mukha

2012-02-01

Full Text Available This article examines the criteria of truth in post-modern philosophy, taking into account the ways it is defined in both the classical and non-classical traditions. Specific to post-modern philosophy is the absence of a universal language of narration and the traditional methods in which knowledge is recognized as legitimate. Basing himself on these concepts, the author examines the problem of the ideal of scientific quality and the transformations this idea has undergone in contemporary philosophy. Truth is understood basically through two means which govern our relation to truth: the will to truth and the concern for truth. These also appear as defining factors of truth in various types of post-modern philosophy: social-operative, social-political, and aesthetic

Compound process fuel cycle concept

International Nuclear Information System (INIS)

Ikegami, Tetsuo

2005-01-01

Mass flow of light water reactor spent fuel for a newly proposed nuclear fuel cycle concept 'Compound Process Fuel Cycle' has been studied in order to assess the capacity of the concept for accepting light water reactor spent fuels, taking an example for boiling water reactor mixed oxide spent fuel of 60 GWd/t burn-up and for a fast reactor core of 3 GW thermal output. The acceptable heavy metal of boiling water reactor mixed oxide spent fuel is about 3.7 t/y/reactor while the burn-up of the recycled fuel is about 160 GWd/t and about 1.6 t/y reactor with the recycled fuel burn-up of about 300 GWd/t, in the case of 2 times recycle and 4 times recycle respectively. The compound process fuel cycle concept has such flexibility that it can accept so much light water reactor spent fuels as to suppress the light water reactor spent fuel pile-up if not so high fuel burn-up is expected, and can aim at high fuel burn-up if the light water reactor spent fuel pile-up is not so much. Following distinctive features of the concept have also been revealed. A sort of ideal utilization of boiling water reactor mixed oxide spent fuel might be achieved through this concept, since both plutonium and minor actinide reach equilibrium state beyond 2 times recycle. Changes of the reactivity coefficients during recycles are mild, giving roughly same level of reactivity coefficients as the conventional large scale fast breeder core. Both the radio-activity and the heat generation after 4 year cooling and after 4 times recycle are less than 2.5 times of those of the pre recycle fuel. (author)

Comprehensive change management concepts. Development of a participatory approach.

Science.gov (United States)

Zink, Klaus J; Steimle, Ulrich; Schröder, Delia

2008-07-01

During the last years, many change projects in organizations did not have the planned success. Therefore at first, the causes for these failures and the success factors contributing to organizational change have to be discussed. To get better results, a comprehensive change management concept has been developed and tested in an ongoing research project. By using concepts for an integrated assessment and design of organizations, an approach for analyzing the current situation has been elaborated to identify "lack of integration" in the change initiatives of a company. To realize an integrated overall approach of modernization by harmonizing different methods and concepts, first, one has to prove their relationship to policy and strategy (vertical harmonization). The second step is to take into account the fact that there has to be a logical fit between the single concepts (horizontal harmonization). But even if all elements are logically coherent, that does not mean that the people working in the company also see this coherence. Therefore, in addition to the "logical fit", one has to examine the "psychological fit". In the end, a concept for analyzing the status quo in an organization as a result of "objective data" and "subjective data" originated. Subsequently, instruments for harmonizing different modernizing concepts have been applied. As part of the comprehensive change management concept participatory ergonomic approaches have been used during the project. The present study shows this approach in the case of one company.

Non-Euclidean Space, Movement and Astronomy in Modern Art: Alexander Calder’s Mobiles and Ben Nicholson’s Reliefs

Directory of Open Access Journals (Sweden)

Malloy Vanja

2013-09-01

Full Text Available John Keats once wrote that ‘there is no such thing as time and space’ rather, believing that time and space are mental constructs that are subject to a variety of forms and as diverse as the human mind. In the 1920s through the 1930s, modern physics in many ways supported this idea through the various philosophical writings on the Theory of General Relativity to the masses by scientists such as Arthur Eddington and Albert Einstein. These new concepts of modern physics fundamentally changed our understanding of time and space and had substantial philosophical implications, which were absorbed by modern artists resulting in the 1936 Dimensionist Manifesto. Seeking to internalize the developments of modern science within modern art, this manifesto was widely endorsed by the most prominent figures of the avant-garde such as Marcel Duchamp, Jean Arp, Naum Gabo, Joan Miró, László Moholy-Nagy, Wassily Kandinsky and Alexander Calder. Of particular interest to this manifesto was the new concept of the fourth-dimension, which in many ways revolutionized the arts. Importantly, its interpretation varied widely in the artistic community, ranging from a purely physical four-dimensional space, to a kinetic concept of space in which space and time are linked, to a metaphysical interest in a space that exists beyond the material realm. The impact of modern science and astronomy on avant-garde art is currently a bourgeoning area of research with considerable implications to our rethinking of substantial artistic figures of this era. Through a case study of Alexander Calder’s Mobiles and Ben Nicholson’s Reliefs, this paper explores how these artworks were informed by an interest in modern science.

THE MORAL CONCEPT IN THE PHILOSOPHY OF KANT

Directory of Open Access Journals (Sweden)

Gheorghe DĂNIȘOR

2016-10-01

Full Text Available The fundamental works in which Kant expounds his theory are The Critique of Pure Reason and The Critique of Practical Reason, and in addition The Critique of the Power of Judgement. In the first of the three, Kant does nothing more than demonstrate the limits of speculative knowledge, that which bestows access to the world of the phenomenon, but which can circumvent the element in itself. Theoretical knowledge is limited to patterns of sensitivity, diversity, placing it under categories enabling the apparatus through which we think. In order to eliminate any confusion regarding the abovementioned elements, Kant, using a footnote, clarifies the connection between morality and freedom: freedom is without a doubt the ratio essendi of moral law, but that the moral law is the ratio cognoscendi of freedom. Kant deliberately draws attention to the fact that freedom and, as a consequence supreme Good, cannot be conceptualised. The so-called Kantian constructivism relies on this pattern of devising freedom as a principle which cannot be demonstrated, the pillar of the entire construction. Good will is what makes duty, categorical imperative, and even freedom possible. Good will has no connection to human sensitivity, it is a concept based on pure reason. This idea leads us to emphasize that Kant wants to demonstrate in his work regarding morality that man becomes free through a detachment from his bodily inclinations. This is a modern perspective. Modernism is dominated by the novelty of founding principles within the subject. Thus, subjectivity becomes the dominant force. But modern subjectivity produces as well the concept of relativism. There is no single or absolute truth, but rather truths individually manufactured that interfere from birth onto a space which exists based on a horizontal arrangement. Last, but not least, there is a modern subjectivity of freedom which is associated to the concept of autonomy.

An axially and radially two-zoned large liquid-metal fast breeder reactor core concept

International Nuclear Information System (INIS)

Kamei, T.; Arie, K.; Moriki, Y.; Suzuki, M.; Yamaoka, M.

1985-01-01

A new core concept that has advantages over conventional homogeneous cores in neutronics characteristics such as power peaking factor, burnup reactivity loss, and reactivity response to the movement of control rods in earthquakes has been evolved. Two options of the new core concept are feasible. One is the so-called axially heterogeneous core, with the internal blanket placed at the lower part of the core. The other concept is similar to the conventional homogeneous core, but has two different plutonium-enriched zones in the axial as well as in the radial direction, so it is a hybrid type of the conventional homogeneous core and the axially heterogeneous core. The new design concept is described and the way that the core characteristics are improved by the chosen key parameters is shown

Byurakan Cosmogony Concept in the Light of Modern Observational Data: Why We Need to Recall it?

Science.gov (United States)

Harutyunian, H. A.

2017-07-01

Some physically possible consequences of interaction between baryonic matter and dark energy are considered. We are arguing that the modern cosmogony and cosmology based on the hypothesis of Kant and Laplace and its further modifications are not adequate to the nowadays growing base of observational data. A thought experiment is conducted in the framework of generally accepted physical concepts and laws to study the most prominent consequences of interactions between various types of substances with the dark energy carrier. Such experiments allow one to arrive at a conclusion that owing to continuous exchanges of energy between the atomic nuclei and the bearer of dark energy, the binding energy of nuclei should reduce and their mass had increase over time. This process can be considered as the Universe total mass growth at the expense of dark energy. Then one would be able to explain the long standing paradox: why the Universe did not collapse immediately after the mass formation event at the very beginning of the Universe formation. On the other hand, this way of thinking leads to a physical picture of the Universe where huge amounts of embryonic baryons possessing of negligible masses can exist in the interiors of large cosmic objects to transform into the ordinary baryonic matter of vast masses in the future. As a result, clumps of matter of huge masses can be ejected from the cores of such objects.

Modern network science has revealed fundamental aspects of normal brain-network organization, such as small-world and scale-free patterns, hierarchical modularity, hubs and rich clubs. The next challenge is to use this knowledge to gain a better understanding of brain disease. Recent developments in the application of network science to conditions such as Alzheimer's disease, multiple sclerosis, traumatic brain injury and epilepsy have challenged the classical concept of neurological disorders being either 'local' or 'global', and have pointed to the overload and failure of hubs as a possible final common pathway in neurological disorders.

2013-01-01

Drug safety is a very basic and fundamental concept in medical practice. ADRs play an important role in assessing patient safety in any system of medicine. Pharmacovigilance study is thus significant to understand treatment outcomes. Current raised issue with respect to complementary and alternative system medicine (CAM) like Ayurveda is increased in number of safety reports along with report misinterpretation; this generates the negative impact on system. Although, Ayurveda which is holistic system of medicine from India has elaborated the causes and methods of drug-induced consequences along with preventive measures the available data in classical texts is scattered. The compilation and analysis along with modern concept drug safety is need of the hour. Present literature review was conducted from various compendium of Ayurveda and electronic data base with search terms of ‘Vyapad’, ‘Viruddha’, ‘Ahita’, ‘herb–herb interaction’, ‘idiosyncrasy’, ‘Prakritiviruddha’ etc. The reported information was analysed for the possible correlation on concept of ADR and Pharmacovigilance of current science. Overall review demonstrated that drug interaction, iatrogenic, over dose, administration of unsuitable drugs, reprehensive drug administration with respect to disease, complication from five procedural therapies (Panchakarma) and reprehensible preparation of mineral drug are nearer to the modern causes of ADR. Thus, concept of drug safety and ADR is not new to the Ayurveda. The concept “Drug which is not appropriate to be used as medicine”(Abheshaja) of Ayurveda sounds similar as that of modern pharmacovigilance. PMID:24563588

Hit-and-run stimulation: a novel concept to reactivate latent HIV-1 infection without cytokine gene induction.

Current antiretroviral therapy (ART) efficiently controls HIV-1 replication but fails to eradicate the virus. Even after years of successful ART, HIV-1 can conceal itself in a latent state in long-lived CD4(+) memory T cells. From this latent reservoir, HIV-1 rebounds during treatment interruptions. Attempts to therapeutically eradicate this viral reservoir have yielded disappointing results. A major problem with previously utilized activating agents is that at the concentrations required for efficient HIV-1 reactivation, these stimuli trigger high-level cytokine gene expression (hypercytokinemia). Therapeutically relevant HIV-1-reactivating agents will have to trigger HIV-1 reactivation without the induction of cytokine expression. We present here a proof-of-principle study showing that this is a possibility. In a high-throughput screening effort, we identified an HIV-1-reactivating protein factor (HRF) secreted by the nonpathogenic bacterium Massilia timonae. In primary T cells and T-cell lines, HRF triggered a high but nonsustained peak of nuclear factor kappa B (NF-kappaB) activity. While this short NF-kappaB peak potently reactivated latent HIV-1 infection, it failed to induce gene expression of several proinflammatory NF-kappaB-dependent cellular genes, such as those for tumor necrosis factor alpha (TNF-alpha), interleukin-8 (IL-8), and gamma interferon (IFN-gamma). Dissociation of cellular and viral gene induction was achievable, as minimum amounts of Tat protein, synthesized following application of a short NF-kappaB pulse, triggered HIV-1 transactivation and subsequent self-perpetuated HIV-1 expression. In the absence of such a positive feedback mechanism, cellular gene expression was not sustained, suggesting that strategies modulating the NF-kappaB activity profile could be used to selectively trigger HIV-1 reactivation.

Steepest-entropy-ascent quantum thermodynamic modeling of the relaxation process of isolated chemically reactive systems using density of states and the concept of hypoequilibrium state

Science.gov (United States)

Li, Guanchen; von Spakovsky, Michael R.

2016-01-01

This paper presents a study of the nonequilibrium relaxation process of chemically reactive systems using steepest-entropy-ascent quantum thermodynamics (SEAQT). The trajectory of the chemical reaction, i.e., the accessible intermediate states, is predicted and discussed. The prediction is made using a thermodynamic-ensemble approach, which does not require detailed information about the particle mechanics involved (e.g., the collision of particles). Instead, modeling the kinetics and dynamics of the relaxation process is based on the principle of steepest-entropy ascent (SEA) or maximum-entropy production, which suggests a constrained gradient dynamics in state space. The SEAQT framework is based on general definitions for energy and entropy and at least theoretically enables the prediction of the nonequilibrium relaxation of system state at all temporal and spatial scales. However, to make this not just theoretically but computationally possible, the concept of density of states is introduced to simplify the application of the relaxation model, which in effect extends the application of the SEAQT framework even to infinite energy eigenlevel systems. The energy eigenstructure of the reactive system considered here consists of an extremely large number of such levels (on the order of 10130) and yields to the quasicontinuous assumption. The principle of SEA results in a unique trajectory of system thermodynamic state evolution in Hilbert space in the nonequilibrium realm, even far from equilibrium. To describe this trajectory, the concepts of subsystem hypoequilibrium state and temperature are introduced and used to characterize each system-level, nonequilibrium state. This definition of temperature is fundamental rather than phenomenological and is a generalization of the temperature defined at stable equilibrium. In addition, to deal with the large number of energy eigenlevels, the equation of motion is formulated on the basis of the density of states and a set of

The Idea of Modernity in Italian Literature at the Turn of the 19th and 20th Centuries

Directory of Open Access Journals (Sweden)

Anastasia V. Golubtsova

2016-09-01

Full Text Available The article analyzes various concepts of modernity in Italian literature at the turn of the 19th and 20th centuries. Modernity is considered a key category of the literary process of the period: different views of modernity reveal philosophical, historical, and aesthetic ideas of the major authors and literary currents. The term modernity in its relation to Italy at the turn of the 19th and 20th centuries may be understood in two different ways: as a specific time period after the unification of Italy and as an aesthetic ideal, both reachable and unreachable. Modernity as a historical period is inseparable from the sense of disappointment and awareness of Italian backwardness and provincialism. The Scapigliati manifest their socio-critical position as a Romantic conflict between individual and society, Verism represents the same idea as a tragic clash of traditional peasant world and modernity that is destroying it. Luigi Pirandello belongs to the same socio-critical tradition. The sense of weariness and decadence is one of the aspects of modern worldview: Gabriele D’Annunzio expresses it in the form of decadent aestheticism; the Crepusculars reject modernity and replace it with the idea of everyday life; Luigi Pirandello puts a special emphasis on the state of perplexity and confusion experienced by a modern man. From the aesthetic point of view, modernity in Italy begins as a struggle against Romanticism; however, here we encounter the controversial nature of the concept again. Giosue Carducci and the Scapigliati reject Italian Romanticism but turn to European Romanticism trying to overcome Italian cultural backwardness. A Verist writer Luigi Capuana elaborates a positivist ideal of modern literature and yet abandons it later. D’Annunzio sees the ideal of modern art in restoring cultural continuity. Futurists, on the contrary, understand modernity as breaking with tradition. Thus, all aesthetic interpretations of modernity in Italy focus

2014-07-01

Full Text Available The dementia concept has been reformulated through its history and the 19th century was remarkable in the construction of this concept as we understand it today. Like other syndromes, much of the history of the dementia concept comes from the attempt to separate it from other nosological conditions, giving it a unique identity. The fundamental elements for the arising of the dementia modern concept were: a correlation of the observed syndrome with organic-cerebral lesions; b understanding of the irreversibility of the dementia evolution; c its relation with human ageing; and d the choice of the cognitive dysfunction as a clinical marker of the dementia concept.

Quadratic reactivity fuel cycle model

International Nuclear Information System (INIS)

Lewins, J.D.

1985-01-01

For educational purposes it is highly desirable to provide simple yet realistic models for fuel cycle and fuel economy. In particular, a lumped model without recourse to detailed spatial calculations would be very helpful in providing the student with a proper understanding of the purposes of fuel cycle calculations. A teaching model for fuel cycle studies based on a lumped model assuming the summability of partial reactivities with a linear dependence of reactivity usefully illustrates fuel utilization concepts. The linear burnup model does not satisfactorily represent natural enrichment reactors. A better model, showing the trend of initial plutonium production before subsequent fuel burnup and fission product generation, is a quadratic fit. The study of M-batch cycles, reloading 1/Mth of the core at end of cycle, is now complicated by nonlinear equations. A complete account of the asymptotic cycle for any order of M-batch refueling can be given and compared with the linear model. A complete account of the transient cycle can be obtained readily in the two-batch model and this exact solution would be useful in verifying numerical marching models. It is convenient to treat the parabolic fit rho = 1 - tau 2 as a special case of the general quadratic fit rho = 1 - C/sub tau/ - (1 - C)tau 2 in suitably normalized reactivity and cycle time units. The parabolic results are given in this paper

A modernized and versatile startup reactivity measuring system installed at NPP Paks and its application for subcritical systems

International Nuclear Information System (INIS)

Czibok, T.; Dezso, Z.; Horvath, Cs.; Lipcsei, S.; Vegh, J.; Pos, I.

2006-01-01

In 2004 the Hungarian Paks NPP completed a project for upgrading the reactivity measuring system applied during reactor startup experiments. Almost all components of the previous system were replaced, only ex-core ionisation chambers remained unaltered. New hardware and software components were introduced for neutron flux signal handling, for data acquisition, as well as for measurement evaluation and data presentation. High-precision picoamper meters were installed at each reactor unit, current signals are handled by a portable signal processing unit. The system applies an accurate on-line reactivity calculation algorithm based on the point-kinetic model with six delayed neutron groups. Detailed off-line evaluation and analysis of startup measurements can be performed on the portable unit, as well. The paper describes the architecture, data acquisition modules, services and man-machine interface of the new system. Functions and results are illustrated with measured data recorded during a startup of Unit 3. In 2003 and 2004 the RMR was installed and tested at all Paks NPP units successfully and now it is in regular use during unit startups. The second part of the paper illustrates an extension of the new system to perform reactivity measurements using the well-known Rossi-α and Feynman-α statistical methods. The modified system was needed to estimate the reactivity of a subcritical system formed by damaged fuel assemblies stored at the fuel service pit of Paks Unit 2. Theoretical background of the applied algorithms is outlined, then results of validation tests and on site measurements are treated. The measurements have shown that the subcriticality of the damaged fuel was sufficiently deep if the high boron concentration in the fuel service pit was maintained

Metaphysical Concept of Secularization versus Islamic Concept of Secularization

2017-12-01

Full Text Available In early 21st century, the question “Is Turkey becoming secularized contrary to popular belief?” was one of the discussions occupying Turkish public opinion. These discussions led to the encounter of two different concepts of secularization, “theological (Islamic” and "metaphysical", and to put forward different claims using the same concept. Hence, it became evidentwas understood that a discussion was necessary to understand what secularization is and what it is not before starting any debate on Turkey's secularization. That is because the metaphysical discussion that defines secularization as the decline in the social influence of metaphysical realm (religion, religion-like mechanisms, folk religions, superstitious beliefs, etc. is overshadowed by the Islamic definition describing secularization as "irreligiousness" or "non-Islamism". Therefore, discussingTo understand the social transformation in Turkey, this article attempts to explain that metaphysical rather than theological definition of secularization is necessary for understanding the social implications of the process of modernization.

Trends vs. reactor size of passive reactivity shutdown and control performance

International Nuclear Information System (INIS)

Wade, D.C.; Fujita, E.K.

1987-01-01

For LMR concepts, the goal of passive reactivity shutdown has been approached in the US by designing the reactors for favorable relationships among the power, power/flow, and inlet temperature coefficients of reactivity, for high internal conversion ratio (yielding small burnup control swing), and for a primary pump coastdown time appropriately matched to the delayed neutron hold back of power decay upon negative reactivity input. The use of sodium bonded metallic fuel pins has facilitated the achievement of the massive shutdown design goals as a consequence of their high thermal conductivity and high effective heavy metal density. Alternately, core designs based on derated oxide pins may be able to achieve the passive shutdown features at the cost of larger core volume and increased initial fissile inventory. For LMR concepts, the passive decay heat removal goal of inherent safety has been approached in US designs by use of pool layouts, larger surface to volume ratio of the reactor vessel with natural draft air cooling of the vessel surface, elevations and redans which promote natural circulation through the core, and thermal mass of the pool contents sufficient to absorb that initial transient decay heat which exceeds the natural draft air cooling capacity. This paper describes current US ''inherently safe'' reactor design

Observation, experiment and hypothesis in modern physical science

CERN Document Server

Hannaway, Owen

1985-01-01

These original contributions by philosophers and historians of science discuss a range of issues pertaining to the testing of hypotheses in modern physics by observation and experiment. Chapters by Lawrence Sklar, Dudley Shapere, Richard Boyd, R. C. Jeffrey, Peter Achinstein, and Ronald Laymon explore general philosophical themes with applications to modern physics and astrophysics. The themes include the nature of the hypothetico-deductive method, the concept of observation and the validity of the theoretical-observation distinction, the probabilistic basis of confirmation, and the testing of idealizations and approximations.The remaining four chapters focus on the history of particular twentieth-century experiments, the instruments and techniques utilized, and the hypotheses they were designed to test. Peter Galison reviews the development of the bubble chamber; Roger Stuewer recounts a sharp dispute between physicists in Cambridge and Vienna over the interpretation of artificial disintegration experiments;...

Fluid-rock interaction: A reactive transport approach

Energy Technology Data Exchange (ETDEWEB)

Steefel, C.; Maher, K.

2009-04-01

Fluid-rock interaction (or water-rock interaction, as it was more commonly known) is a subject that has evolved considerably in its scope over the years. Initially its focus was primarily on interactions between subsurface fluids of various temperatures and mostly crystalline rocks, but the scope has broadened now to include fluid interaction with all forms of subsurface materials, whether they are unconsolidated or crystalline ('fluid-solid interaction' is perhaps less euphonious). Disciplines that previously carried their own distinct names, for example, basin diagenesis, early diagenesis, metamorphic petrology, reactive contaminant transport, chemical weathering, are now considered to fall under the broader rubric of fluid-rock interaction, although certainly some of the key research questions differ depending on the environment considered. Beyond the broadening of the environments considered in the study of fluid-rock interaction, the discipline has evolved in perhaps an even more important way. The study of water-rock interaction began by focusing on geochemical interactions in the absence of transport processes, although a few notable exceptions exist (Thompson 1959; Weare et al. 1976). Moreover, these analyses began by adopting a primarily thermodynamic approach, with the implicit or explicit assumption of equilibrium between the fluid and rock. As a result, these early models were fundamentally static rather than dynamic in nature. This all changed with the seminal papers by Helgeson and his co-workers (Helgeson 1968; Helgeson et al. 1969) wherein the concept of an irreversible reaction path was formally introduced into the geochemical literature. In addition to treating the reaction network as a dynamically evolving system, the Helgeson studies introduced an approach that allowed for the consideration of a multicomponent geochemical system, with multiple minerals and species appearing as both reactants and products, at least one of which could be

Non-intrusive appliance load monitoring system based on a modern kWh-meter

Energy Technology Data Exchange (ETDEWEB)

Pihala, H. [VTT Energy, Espoo (Finland). Energy Systems

1998-12-01

Non-intrusive appliance load monitoring (NIALM) is a fairly new method to estimate load profiles of individual electric appliances in a small building, like a household, by monitoring the whole load at a single point with one recording device without sub-meters. Appliances have special electrical characteristics, the positive and negative active and reactive power changes during the time they are switched on or off. These changes are called events and are detected with a monitoring device called an event recorder. Different NIALM-concepts developed in Europe and in the United States are generally discussed. The NIALM-concept developed in this study is based on a 3-phase, power quality monitoring kWh-meter and unique load identification algorithms. This modern kWh-meter with a serial data bus to a laptop personal computer is used as die event recorder. The NIALM-concept of this presentation shows for the first time how a kWh-meter can be used at the same time for billing, power quality and appliance end-use monitoring. An essential part of the developed NIALM-system prototype is the software of load identification algorithms which runs in an off-line personal computer. These algorithms are able to identify, with a certain accuracy, both two-state and multi-state appliances. This prototype requires manual-setup in which the naming of appliances is performed. The results of the prototype NIALMS were verified in a large, single family detached house and they were compared to the results of other prototypes in France and the United States, although this comparison is difficult because of different supply systems, appliance stock and number of tested sites. Different applications of NIALM are discussed. Gathering of load research data, verification of DSM-programs, home automation, failure analysis of appliances and security surveillance of buildings are interesting areas of NIALM. Both utilities and customers can benefit from these applications. It is possible to

ABSTRACT : INTRODUCTION : The massive-transfusion concept was introduced to recognize the dilutional complications resulting from large volumes of packed red blood cells (PRBCs). Definitions of massive transfusion vary and lack supporting clinical evidence. Damage-control resuscitation regimens...... of modern trauma care are targeted to the early correction of acute traumatic coagulopathy. The aim of this study was to identify a clinically relevant definition of trauma massive transfusion based on clinical outcomes. We also examined whether the concept was useful in that early prediction of massive...... transfusion as a concept in trauma has limited utility, and emphasis should be placed on identifying patients with massive hemorrhage and acute traumatic coagulopathy....

The Pioneering Work of Enrico Morselli (1852-1929) in Light of Modern Scientific Research on Hypnosis and Suggestion.

Bartolucci, Chiara; Lombardo, Giovanni Pietro

2017-01-01

This article examines research on hypnosis and suggestion, starting with the nineteenth-century model proposed by Enrico Morselli (1852-1929), an illustrious Italian psychiatrist and psychologist. The authors conducted an original psychophysiological analysis of hypnosis, distancing the work from the neuropathological concept of the time and proposing a model based on a naturalistic approach to investigating mental processes. The issues investigated by Morselli, including the definition of hypnosis and analysis of specific mental processes such as attention and memory, are reviewed in light of modern research. From the view of modern neuroscientific concepts, some problems that originated in the nineteenth century still appear to be present and pose still-open questions.

Theoretical study of some aspects of the nucleo-bases reactivity: definition of new theoretical tools for the study of chemical reactivity

International Nuclear Information System (INIS)

Labet, V.

2009-09-01

In this work, three kinds of nucleo-base damages were studied from a theoretical point of view with quantum chemistry methods based on the density-functional theory: the spontaneous deamination of cytosine and its derivatives, the formation of tandem lesion induced by hydroxyl radicals in anaerobic medium and the formation of pyrimidic dimers under exposition to an UV radiation. The complementary use of quantitative static methods allowing the exploration of the potential energy surface of a chemical reaction, and of 'conceptual DFT' principles, leads to information concerning the mechanisms involved and to the rationalization of the differences in the nucleo-bases reactivity towards the formation of a same kind of damage. At the same time, a reflexion was undertaken on the asynchronous concerted mechanism concept, in terms of physical meaning of the transition state, respect of the Maximum Hardness Principle, and determination of the number of primitive processes involved. Finally, a new local reactivity index was developed, relevant to understand the reactivity of a molecular system in an excited state. (author)

Conception, design and development of a low-cost intelligent prosthesis for one-sided transfemoral amputees

Directory of Open Access Journals (Sweden)

Wilson Carlos da Silva Júnior

Full Text Available Introduction Modern transfemoral knee prostheses are designed to offer comfort and self-confidence to amputees. These prostheses are mainly based upon either a passive concept, with a damping system, or an active computational intelligent design to control knee motion during the swing phase. In Brazil, most lower extremity amputees are unable to afford modern prostheses due to their high cost. In this work, we present the conception, design and development of a low-cost intelligent prosthesis for one-sided transfemoral amputees. Methods The concept of the prosthesis is based on a control system with sensors for loads, which are installed on the amputee’s preserved leg and used as a mirror for the movement of the prosthesis. Mechanical strength analysis, using the Finite Element Method, electromechanical tests for the sensors and actuators and verification of data acquisition, signal conditioning and data transferring to the knee prosthesis were performed. Results The laboratory tests performed showed the feasibility of the proposed design. The electromechanical concept that was used enabled a controlled activation of the knee prosthesis by the two load cells located on the shoe sole of the preserved leg. Conclusions The electromechanical design concept and the resulting knee prosthesis show promising results concerning prosthesis activation during walking tests, thereby showing the feasibility of a reduced manufacturing cost compared to the modern prostheses available on the market.

2014-01-01

Full Text Available The article considers evolution of development of the paradigm of ensuring competitive advantages of an enterprise. Foreign and domestic scientists focus on individual directions of development of competitive advantages and pay insufficient attention to new management concepts – development of the information society, knowledge economy and dynamism of integration processes. The goal of the study is formation of the modern paradigm of ensuring competitive advantages of an enterprise with consideration of tendencies of development of the knowledge economy, information society and integration processes. Enterprise competitiveness is a synergetic characteristic, which reflects enterprise capability of dynamic response to changes of the market situation with the aim of keeping predominance over other economic subjects. Management of the future, on the basis of the management 2.0 concept, should take into account interests not only of top management and shareholders but also employees, local communities and territories and meet requirements of the society in general, individual groups of consumers and tendencies of development of managerial and information technologies. The paradigm of the modern theory of ensuring competitive advantages should include models of keeping competitive advantages in the existing markets and models of development of future markets; strategy of development of enterprise competitiveness, human capital development and efficient enterprise management.

The Framatome RCVS concept and physics

Vallee, A.; Millot, J.P.; Bruna, G.

1986-06-01

We have tried through this presentation to emphasize on what FRAMATOME thinks to be the most specific problems of the advanced RCVS (Reactor core with spectral shift) core concept (Spectral shift, voidage, reactivity control). Besides, FRAMATOME is analysing the most important safety related topics typically LOCA and DNBR, and has launched developments on them, in connection with CEA. The core behaviour during a loss of Coolant Accident is quite similar to PWR's, the pitch between rods being sufficiently large for clad ballooning not to cause any damage. To conclude, the core improvements developed by FRAMATOME on the RCVS concept economize the use of fissile materials

Unifying concepts linking dissolved organic matter composition to persistence in aquatic ecosystems

Kellerman, Anne M.; Guillemette, François; Podgorski, David C.; Aiken, George R.; Butler, Kenna D.; Spencer, Robert G. M.

2018-01-01

The link between composition and reactivity of dissolved organic matter (DOM) is central to understanding the role aquatic systems play in the global carbon cycle; yet, unifying concepts driving molecular composition have yet to be established. We characterized 37 DOM isolates from diverse aquatic ecosystems, including their stable and radiocarbon isotopes (δ13C-dissolved organic carbon (DOC) and Δ14C-DOC), optical properties (absorbance and fluorescence), and molecular composition (ultrahigh resolution mass spectrometry). Isolates encompassed end-members of allochthonous and autochthonous DOM from sites across the United States, the Pacific Ocean, and Antarctic lakes. Modern Δ14C-DOC and optical properties reflecting increased aromaticity, such as carbon specific UV absorbance at 254 nm (SUVA254), were directly related to polyphenolic and polycyclic aromatic compounds, whereas enriched δ13C-DOC and optical properties reflecting autochthonous end-members were positively correlated to more aliphatic compounds. Furthermore, the two sets of autochthonous end-members (Pacific Ocean and Antarctic lakes) exhibited distinct molecular composition due to differences in extent of degradation. Across all sites and end-members studied, we find a consistent shift in composition with aging, highlighting the persistence of certain biomolecules concurrent with degradation time.

THE IMPACT OF POWER COEFFICIENT OF REACTIVITY ON CANDU 6 REACTORS

Directory of Open Access Journals (Sweden)

D. KASTANYA

2013-10-01

Full Text Available The combined effects of reactivity coefficients, along with other core nuclear characteristics, determine reactor core behavior in normal operation and accident conditions. The Power Coefficient of Reactivity (PCR is an aggregate indicator representing the change in reactor core reactivity per unit change in reactor power. It is an integral quantity which captures the contributions of the fuel temperature, coolant void, and coolant temperature reactivity feedbacks. All nuclear reactor designs provide a balance between their inherent nuclear characteristics and the engineered reactivity control features, to ensure that changes in reactivity under all operating conditions are maintained within a safe range. The CANDU® reactor design takes advantage of its inherent nuclear characteristics, namely a small magnitude of reactivity coefficients, minimal excess reactivity, and very long prompt neutron lifetime, to mitigate the demand on the engineered systems for controlling reactivity and responding to accidents. In particular, CANDU reactors have always taken advantage of the small value of the PCR associated with their design characteristics, such that the overall design and safety characteristics of the reactor are not sensitive to the value of the PCR. For other reactor design concepts a PCR which is both large and negative is an important aspect in the design of their engineered systems for controlling reactivity. It will be demonstrated that during Loss of Regulation Control (LORC and Large Break Loss of Coolant Accident (LBLOCA events, the impact of variations in power coefficient, including a hypothesized larger than estimated PCR, has no safety-significance for CANDU reactor design. Since the CANDU 6 PCR is small, variations in the range of values for PCR on the performance or safety of the reactor are not significant.

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.

Jastifer, James R; Toledo-Pereyra, Luis H

2012-10-01

Leonardo da Vinci (1452-1519), world-renowned Italian renaissance master, is known for his contributions to, and broad interests in science and art. The objective of this work is to demonstrate the extent of his science by applying the use of his concepts to current models of foot and ankle mechanics. The art and science of Leonardo Da Vinci were extensively analyzed by reviewing his original drawings and hand written notebooks as well as their English translation. Current medical journals including the topics of foot, ankle, and biomechanics were reviewed for modern evidence and application of his concepts. The library of Michigan State University and the electronic library of the Royal Library at Windsor Castle were extensively utilized. From the depths of Santa Maria Nuova Hospital in Florence and Santo Spirito Hospital in Rome, through his commentary and anatomical drawings of around 30 cadaver dissections he performed, Leonardo da Vinci expressed his concept of foot and ankle anatomy and mechanics. He laid forth concepts, which vary little from current theories including those of proportion, statics and joint stability, sesamoid biomechanics, and structural support of the foot. Leonardo da Vinci, by combining an interest in anatomy and a gift of genius and artistic ability laid a foundation of foot and ankle anatomy and mechanics that have been applied in modern clinical sciences. Leonardo in this way made important contributions to the practice of foot and ankle orthopedics.

The concept of a bilingual dictionary

DEFF Research Database (Denmark)

Tarp, Sven

2005-01-01

The term bilingual dictionary is widely used, not only by librarians and dictionary users en general but also by professional lexicographers dedicated to the theory and practice of dictionary making. For this reason it should be expected that there were a common and well-established definition...... of the concept of a bilingual dictionary. It is evident that most people has an intuitive idea of what is meant by «bilingual dictionary». But science-based lexicographic theory - at least if it wants to be considered as such - must go beyond intuition and furnish precise definitions of the concepts used...... chapters, various definitions will be discussed and related to dictionary practice and, subsequently, the very concept of a bilingual dictionary will be examined in the light of a dictionary typology based upon the modern theory of lexicographic functions....

THE HEURISTIC POTENTIAL OF ANOMIE THEORY IN MODERN CRIMINOLOGY

Directory of Open Access Journals (Sweden)

Alexander Vladislavovich Pletnev

2015-01-01

Full Text Available This article deals with modern English theories of anomie. They can be used in Russian criminology.  The main goal of article consists in detection of actual theories of anomie and definition of prospects of their use. As modern theories of anomie are poorly submitted in the Russian sociological and criminological literature, the subject of research is actual. This work contains the analysis of opportunities for adoption of modern conceptions of anomie of individual in Russian practice. During research development of the theory of anomie in the history of sociology was considered. The problem of anomie was admitted actual antique Greece. Anomie which is today concerned with normlessness and related to alienation is associated primarily with the works of Durkheim and Merton. Anomia developed in research by MacIver and Srole as a characteristic of individuals and related to the breakdown of the individual’s sense of attachment to society. Results of theoretical research show that theories of anomie of the personality have the greatest heuristic potential for modern Russian science. Other important conclusion of research is one that the anomie can have some sources of emergence. Further studying of this subject is necessary because English-language theories of anomie contain a set of theoretical and empirical results which can be used in the Russian criminology.

Extended reactivity trace curves for nuclear power control with no power shooting

Energy Technology Data Exchange (ETDEWEB)

Ratemi, W M; Elbuni, M S [Faculty of engineering, Al Fateh universty Tripoli (Libyan Arab Jamahiriya)

1995-10-01

This paper introduces a new concept of reactivity trace curve (RTC) for nuclear power control with no power shooting. The concept is based on recent work of bernard et al. on the dynamic period of nuclear reactors. RTC-method is simulated for both a static effective decay constant corresponding to a one-group delayed neutrons model, and a dynamic effective decay constant corresponding to a six-group delayed neutrons model. A fitting to the RTC of a six-group reactor model resulted in a closed from formula for the RTC that couples the effect of both static and dynamic decay constants. Hence, introducing two `fingerprints` for the reactor in concern to identify a closed from RTC formula capable of controlling the reactor power. Integration of the RTC with control rod integral curves results in the {rho}-z-t diagram. This diagram relates the amount of recommended reactivity (RTC), the position of control rod, and the time required for power control. 8 figs.

Low-grade chronic inflammation perpetuated by modern diet as a promoter of obesity and osteoporosis.

Science.gov (United States)

Ilich, Jasminka Z; Kelly, Owen J; Kim, Youjin; Spicer, Maria T

2014-06-01

Some of the universal characteristics of pre-agricultural hominin diets are strikingly different from the modern human diet. Hominin dietary choices were limited to wild plant and wild animal foods, while the modern diet includes more than 70 % of energy consumed from refined sugars, refined vegetable oils, and highly processed cereals and dairy products. The modern diet, with higher intake of fat has also resulted in a higher ratio of omega-6 (n-6) to omega-3 (n-3) polyunsaturated fatty acids (PUFA), contributing to low-grade chronic inflammation (LGCI) and thus promoting the development of many chronic diseases, including obesity and osteoporosis. In this review, we describe the changes in modern diet, focusing on the kind and amount of consumed fat; explain the shortcomings of the modern diet with regard to inflammatory processes; and delineate the reciprocity between adiposity and inflammatory processes, with inflammation being a common link between obesity and osteoporosis. We present the evidence that overconsumption of n-6 PUFA coupled with under-consumption of n-3 PUFA results in LGCI and, along with the increased presence of reactive oxygen species, leads to a shift in mesenchymal stem cells (precursors for both osteoblasts and adipocytes) lineage commitment toward increased adipogenesis and suppressed osteoblastogenesis. In turn, high n-6 to n-3 PUFA ratios in the modern diet, coupled with increased synthesis of pro-inflammatory cytokines due to adiposity, propagate obesity and osteoporosis by increasing or maintaining LGCI.

Hamiltonian inclusive fitness: a fitter fitness concept.

Science.gov (United States)

Costa, James T

2013-01-01

In 1963-1964 W. D. Hamilton introduced the concept of inclusive fitness, the only significant elaboration of Darwinian fitness since the nineteenth century. I discuss the origin of the modern fitness concept, providing context for Hamilton's discovery of inclusive fitness in relation to the puzzle of altruism. While fitness conceptually originates with Darwin, the term itself stems from Spencer and crystallized quantitatively in the early twentieth century. Hamiltonian inclusive fitness, with Price's reformulation, provided the solution to Darwin's 'special difficulty'-the evolution of caste polymorphism and sterility in social insects. Hamilton further explored the roles of inclusive fitness and reciprocation to tackle Darwin's other difficulty, the evolution of human altruism. The heuristically powerful inclusive fitness concept ramified over the past 50 years: the number and diversity of 'offspring ideas' that it has engendered render it a fitter fitness concept, one that Darwin would have appreciated.

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. The paper facilitates a better understanding of modern leadership, emphasizing the case of S. Jobs, and provides a platform on which to build further studies on the same subject.

Science.gov (United States)

Nelson, Kurt

1991-01-01

The avionics system for the Centaur upper stage is in the process of being modernized with the current state-of-the-art in strapdown inertial guidance equipment. This equipment includes an integrated flight control processor with a ring laser gyro based inertial guidance system. This inertial navigation unit (INU) uses two MIL-STD-1750A processors and communicates over the MIL-STD-1553B data bus. Commands are translated into load activation through a Remote Control Unit (RCU) which incorporates the use of solid state relays. Also, a programmable data acquisition system replaces separate multiplexer and signal conditioning units. This modern avionics suite is currently being enhanced through independent research and development programs to provide autonomous rendezvous and docking capability using advanced cruise missile image processing technology and integrated GPS navigational aids. A system concept was developed to combine these technologies in order to achieve a fully autonomous rendezvous, docking, and autoland capability. The current system architecture and the evolution of this architecture using advanced modular avionics concepts being pursued for the National Launch System are discussed.

Performance of the Lead-Alloy Cooled Concept Balanced for Actinide Burning and Electricity Production

International Nuclear Information System (INIS)

Pavel Hejzlar; Cliff Davis

2004-01-01

A lead-bismuth-cooled fast reactor concept targeted for a balanced mission of actinide burning and low-cost electricity production is proposed and its performance analyzed. The design explores the potential benefits of thorium-based fuel in actinide-burning cores, in particular in terms of the reduction of the large reactivity swing and enhancement of the small Doppler coefficient typical of fertile-free actinide burners. Reduced electricity production cost is pursued through a longer cycle length than that used for fertile-free burners and thus a higher capacity factor. It is shown that the concept can achieve a high transuranics destruction rate, which is only 20% lower than that of an accelerator-driven system with fertile-free fuel. The small negative fuel temperature reactivity coefficient, small positive coolant temperature reactivity coefficient, and negative core radial expansion coefficient provide self-regulating characteristics so that the reactor is capable of inherent shutdown during major transients without scram, as in the Integral Fast Reactor. This is confirmed by thermal-hydraulic analysis of several transients without scram, including primary coolant pump trip, station blackout, and reactivity step insertion, which showed that the reactor was able to meet all identified thermal limits. However, the benefits of high actinide consumption and small reactivity swing can be attained only if the uranium from the discharged fuel is separated and not recycled. This additional uranium separation step and thorium reprocessing significantly increase the fuel cycle costs. Because the higher fuel cycle cost has a larger impact on the overall cost of electricity than the savings from the higher capacity factor afforded through use of thorium, this concept appears less promising than the fertile-free actinide burners

Full Text Available Physics is engaged in scientific and technological development in several areas, however, its learning in high school has high failure rates that demonstrate a low level of use. It is a science that allows us to understand the nature of the macroscopic and atomic matter, but it is taught in a disjointed manner, upon presentation of concepts, laws and mathematical sentences, repetitive exercises that have taken the preparatory character for college entrance. Thus, the student gets stuck sentences featuring a partial knowledge and disposable. This study aimed to analyze the main difficulties that undergraduate students in Physics have in Modern Physics learning. Point out the difficulties in teaching and learning Physics is not an easy task and to identify them comes the difficulty of how to solve them. After analysis of several hypotheses we can conclude that there is no single factor responsible for the difficulty of the teaching and learning of Modern Physics. The lack of time to work and developed since middle school, stimulating the curiosity of students, adequately trained teachers, lack of structure offered by the government, parents' responsibilities and students in learning, among others, constitute a major challenge for successful teaching and learning of Modern Physics

The article analyzes the basic problems of evaluation the effectiveness of civil service modernization and scientific papers on these issues. The basic theoretical approaches to the definition of «assessment» and «evaluation» are studied. Existing theoretical and methodological approaches to the assessment process are analyzed and summarized, the main methods of evaluating the effectiveness of the civil service modernization and the most common assessment methods are defined. Eligible for evaluating the effectiveness of civil service modernization are special analytical techniques: functional review, Balanced Scorecard, taxonomic analysis, Key Performance Indicators, methods of multivariate analysis and others. Among the methods of studying consumer expectations about the effectiveness of the civil service modernization such ones are singled out: questionnaires, surveys, interviews, testing, monitoring, analysis of statistical sources, contents of documents, reports and regulatory framework and others. The methods of improving efficiency include: benchmarking, reengineering, performance assessment models and more. The importance of gradual replacement of cost evaluation methods by the results evaluation method is determined. It was shown the need for a comprehensive balanced scorecard to evaluate. With a view to the mutual agreement of principles, mechanisms and instruments for evaluating the effectiveness of civil service modernization the expediency of a systematic, targeted, synergistic, process, situational, strategic and resource approaches is grounded. Development of theoretical concepts and methodological principles of evaluating the effectiveness of civil service modernization should be based on the harmonious combination (integration of all

Dreamscapes of Modernity offers the first book-length treatment of sociotechnical imaginaries, a concept originated by Sheila Jasanoff and developed in close collaboration with Sang-Hyun Kim to describe how visions of scientific and technological progress carry with them implicit ideas about public purposes, collective futures, and the common good. The book presents a mix of case studies-including nuclear power in Austria, Chinese rice biotechnology, Korean stem cell research, the Indonesian Internet, US bioethics, global health, and more-to illustrate how the concept of sociotechnical imaginaries can lead to more sophisticated understandings of the national and transnational politics of science and technology. A theoretical introduction sets the stage for the contributors' wide-ranging analyses, and a conclusion gathers and synthesizes their collective findings. The book marks a major theoretical advance for a concept that has been rapidly taken up across the social sciences and promises to become central to...

Reactivity and reactions to regulatory transparency in medicine, psychotherapy and counselling.

McGivern, Gerry; Fischer, Michael D

2012-02-01

We explore how doctors, psychotherapists and counsellors in the U.K. react to regulatory transparency, drawing on qualitative research involving 51 semi-structured interviews conducted during 2008-10. We use the concept of 'reactivity mechanisms' (Espeland & Sauder, 2007) to explain how regulatory transparency disrupts practices through simplifying and decontextualizing them, altering practitioners' reflexivity, leading to defensive forms of practice. We make an empirical contribution by exploring the impact of transparency on doctors compared with psychotherapists and counsellors, who represent an extreme case due to their uniquely complex practice, which is particularly affected by this form of regulation. We make a contribution to knowledge by developing a model of reactivity mechanisms, which explains how clinical professionals make sense of media and professional narratives about regulation in ways that produce emotional reactions and, in turn, defensive reactivity to transparency.

[Problems associated with the prevention of cruelty to animals in modern livestock breeding (author's transl)].

Science.gov (United States)

Schultze-Petzold, H

1976-01-01

Regulations for the protection of useful animals can be traced to the early history of Law. The reason for such regulations has hardly changed up to the present: the expedient incorporation of the animal into the hierachy of values of the prevailing times. Decisive impulses invariably originated from the legal conception, the need for legal protection as well as from the scientific conceptions of society. The development rarely took a linear course and was not without setbacks. The prevention of cruelty to animals has always been faced with particular conflicting situations. Our pluralistic society with its marked philosophy of profit-making has to face such a problem, in particular as a result of livestock keeping in modern systems. The necessity and legitimacy of a permanent supply of large quantities of high-grade animal foodstuffs to be offered to our present industrial society on a competitive and low-cost basis, have contributed to this development. The public and parliament have for some time been demanding a modern federal act for the prevention of cruelty to animals based on a technical conception allowing also those questions of animal protection related to the present keeping of useful animals to be integrated, thus achieving a gradual balancing of interests. Such an Animal Protection Act came into force on October 1, 1972. On account of its scientific orientation it prompts us to give renewed thought to many present-day ideas about the keeping of animals, especially of useful animals, employing modern systems. With this objective in mind the Act has already strongly influenced the developing international harmonization of provisions for Animal Protection. The problems linked with "Animal Protection/Keeping of Useful Animals" require a harmonization of the ethical, scientific, economic and legal aspects as an indispensable prerequisite. On the basis of expert opinions prepared by a group of specialists of the Federal Ministry of Agriculture on the

Full Text Available The modernization period in the 19th century caused important changes in systems of both travel and accommodation systems. These changes inevitably affected the architecture of hotels and other buildings offering accommodation. The first modern hotels were opened in Galata and Pera by the date of 1840. (It means first hotel opened in 1840 and then the other hotels began to open Later hotels began to serve tje in Eminönü, Kadıköy, Boğaziçi, Adalar, Şişli, Feriköy and Yeşilköy regions. The opening and development of hotels has continued until the beginning of the First World War in 1914. There were hotels with suit rooms and some communal space and there were also hotels which were as luxurious and wellequipped as European hotels. First hotels were traditionally built of wood or stone, and had only two or three floors. At the end of the century, hotels were modern structures built using modern materials such as brick and steel, larger and higher than their predecessors. Beside that these hotels did not have typical facades, they were constructed with traditional, neoclassical or mixed facades. The grand luxury hotels were designed by famous European architects and craftsmen and often magnificently decorated. These grand hotels are also important because of the technical equipment and technology at the date they were built. Because of being very important point for many in the domain of science, modernization period hotels of Istanbul’s are studied by many aspects as urbanisme, architecture, preservation, tourism and sustainability. In addition, the hotels are evaluated in terms of commerce and managerment conception, socio-economic status and political importance. And then it is defined deformations and their causes of these hotels. Finally suggestions are made that would remove these deformations. It is believed the data included in this work will be helpfull for planning, arranging and conservation works in Istanbul.

Modern imaging technology for childhood urinary tract infection; Moderne Bildgebung beim Harnweginfekt im Kindesalter

Energy Technology Data Exchange (ETDEWEB)

Riccabona, M.; Fotter, R. [Radiologische Universitaetsklinik Graz (Germany). Abteilung Kinderradiologie

2005-12-01

Imaging in childhood urinary tract infection (UTI) is still a matter of debate. There are established guidelines, however new knowledge and the changed medical environment have enhanced this ongoing discussion. These new insights have impacted therapy and consequently the imaging algorithm. Modern imaging methods - particularly MRI and modern ultrasound (US) - are less invasive with a lower radiation burden. Additionally, it has been shown that VUR is a poor predictor for renal scarring out, which affects long-term results. Furthermore, the majority of UT malformations is depicted by prenatal US. The most crucial aspect of improving long-term outcome appears to be the early and reliable depiction of UTI and effective treatment to prevent renal scarring. This review tries to present this new knowledge and to discuss the potential of modern imaging. Recent changes in imaging algorithms are highlighted and an outcome-oriented algorithm that addresses these recent developments is proposed, without lightly abandoning established standards. It consists of an orienting US and - for depiction of renal involvement - amplitude coded color Doppler sonography or renal static scintigraphy (considered the gold standard, particularly for evaluating scars); in future MRI may play a role. Based on this concept, only patients with renal damage as well as patients with complex urinary tract malformations or intractable recurrent UTI may have to undergo VCUG. (orig.) [German] Die bildgebende Diagnostik beim kindlichen Harnweginfekt (HWI) wird weiterhin heftig diskutiert.

Full Text Available This article discusses the role of social and environmental enterprises revealed in the concept of Corporate Social Responsibility (CSR and analyzed in the light of Ecological Modernization Theory (TME.The overall objective of this study is to understand CSR from the perspectiveof TME through more detailed research of a CSR program called  Clube dos Produtores [Producers Club].This program aims to influence the supply chain to adopt responsible and sustainable practices, and seeks to strengthen the small and medium producers through structured actions, such as training, qualification, and inspection, stimulating quality, innovation and productivity growth. It is conducted in parallel, in Portugal, by the Rede Sonae de Distribuição and, in Brazil, by Walmart Company. The data collection included both Countries. In Portugal, the Clube dos Produtores has emerged to combine the synergy between distribution and production and promote the development of domestic production. It takes the environment as the genesis for its creation, maintains a nationalist approach by encouraging the consumption of domestic products, and recognizes consumer pressure as the force for continuous innovation of products and services. In addition, it reconciles tradition and modernity through products supported by different generations. In Brazil, the Club is founded on the sustainability discourse; the customer awareness about environmental issues was not captured in the research; the producers innovations result from their own initiatives to participate in fairs or from direct contact with consumers; the dialogue between tradition and modernity occurs primarily through the entrepreneurial capacity of the producers and less direct intervention by Walmart.

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

In the early 1920s, the film industry seized on the furor over the modern girls' demands for sexual liberty and fulfillment inside and outside of marriage to introduce not only new subject matter, but new modes of addressing its diverse audience. Social upheaval in this period coincided with the media industries' movement toward unprecedented speed of adaptation and cooperation, making possible a powerful new intermediality. The film industry used this to generate layered meanings beyond the confines of the film text, encouraging bold viewers to see through the camouflage with which it sought to appease more traditionalist audience members. With Flaming Youth, through a smokescreen of melodramatic conventions and moral lessons, it delivered a strikingly modern conception of sexuality and marriage to the big screen.

Detection of Pesticides and Pesticide Metabolites Using the Cross Reactivity of Enzyme Immunoassays

2001-01-01

Enzyme immunoassay is an important environmental analysis method that may be used to identify many pesticide analytes in water samples. Because of similarities in chemical structure between various members of a pesticide class, there often may be an unwanted response that is characterized by a percentage of cross reactivity. Also, there may be cross reactivity caused by degradation products of the target analyte that may be present in the sample. In this paper, the concept of cross reactivity caused by degradation products or by nontarget analytes is explored as a tool for identification of metabolites or structurally similar compounds not previously known to be present in water samples. Two examples are examined in this paper from various water quality studies. They are alachlor and its metabolite, alachlor ethane sulfonic acid, and atrazine and its class members, prometryn and propazine. A method for using cross reactivity for the detection of these compounds is explained in this paper.

Full Text Available Globalized development strategies in industry are currently focused on developing intelligent manufacturing concepts called Industry 4.0. Companies around the world will be forced to adopt this concept, especially in terms of maintaining competitiveness. One of the most serious obstacles of developing the concept of intelligent production is physical and moral obsolescence of the manufacturing base in general. Despite the fact that companies have historically renewed their manufacturing base, automated and robotized manufacturing processes and systems, nowadays highly current question of determining the form and timing of further modernization and renewal of the manufacturing base for intelligent production purposes. The authors present a model to determine optimal time to start upgrading and renewing the production base based on formulating and comparing costs of means of production throughout their lifecycle, including consideration of their moral obsolescence.

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....

Living autobiographically: Concepts of aging and artistic expression in painting and modern dance.

Banerjee, Mita; Wohlmann, Anita; Dahm, Ralf

2017-01-01

This article discusses the ways in which artists have incorporated or failed to incorporate the aging process of their bodies into their art. Using Russian ballet dancer Mikhail Baryshnikov and the French painter Claude Monet as cases in point, we explore situations in which physical changes brought about by aging compromises artists' ability to engage with their artistic medium. Connecting Monet's oeuvre and Baryshnikov's dance performances to life writing accounts, we draw on John Paul Eakin's concept of "living autobiographically": In this vein, life writing research does not only have to take into account concepts of identity as they emerge from life writing narratives, but it also needs to explore the somatic, corporeal and material dimensions of these narratives.

Simplified reactive power management strategy for complex power grids under stochastic operation and incomplete information

International Nuclear Information System (INIS)

Vlachogiannis, John G.

2009-01-01

In the current released energy market, the large-scale complex transmission networks and the distribution ones with dispersed energy sources and 'intelligent' components operate under uncertainties, stochastic and prior incomplete information. A safe and reliable operation of such complex power grids is a major issue for system operators. Under these circumstances an online reactive power management strategy with minimum risk concerning all uncertain and stochastic parameters is proposed. Therefore, new concepts such as reactive power-weighted node-to-node linking and reactive power control capability are introduced. A distributed and interconnected stochastic learning automata system is implemented to manage, in a unified and unique way, the reactive power in complex power grids with stochastic reactive power demand and detect the vulnerable part. The proposed simplified strategy can also consider more stochastic aspects such as variable grid's topology. Results of the proposed strategy obtained on the networks of IEEE 30-bus and IEEE 118-bus systems demonstrate the effectiveness of the proposed strategy.

Strength and Numerical Analysis in the Design of Permeable Reactive Barriers

Pawluk, Katarzyna; Wrzesiński, Grzegorz; Lendo-Siwicka, Marzena

2017-10-01

Permeable reactive barriers are one of the most important in situ technologies in groundwater remediation. Most of the installed PRBs have tended to use singular reactive media, but there is an increasing number of applications using combined or sequenced media to treat mixtures of contaminants within a groundwater plume. The concept of a multi-layered permeable reactive barrier (MPRB) to prevent and protect groundwater along traffic routes, especially in ecologically and naturally valuable areas, was developed following several field and laboratory investigations conducted in the Department of Geotechnical Engineering of the Warsaw University of Life Sciences. In accordance with the guidelines of the Interstate Technology & Regulatory Council for the selection of reactive materials, numerous laboratory and field investigations should be performed to determine the environmental conditions, type and concentrations of the contaminants, and the physical-chemical and permeability properties of the reactive materials. However, the deformation and strength properties of the reactive materials should be also considered in the design and evaluation of the safety conditions. In this paper, strength and deformation properties of silica spongolite, zeolite, and activated carbon were investigated using direct shear and oedometer tests. The laboratory test results were used in numerical calculations with the application of the finite element method. The aim of this study was to define the impact of the installation stages of a multi-layered permeable reactive barrier on the stability of a road embankment. Numerical analysis may prevent, reduce or eliminate the risk in the case of a breakdown during the construction or/and exploitation of a PRB.

Performance of the Lead-Alloy-Cooled Reactor Concept Balanced for Actinide Burning and Electricity Production

International Nuclear Information System (INIS)

Hejzlar, Pavel; Davis, Cliff B.

2004-01-01

A lead-bismuth-cooled fast reactor concept targeted for a balanced mission of actinide burning and low-cost electricity production is proposed and its performance analyzed. The design explores the potential benefits of thorium-based fuel in actinide-burning cores, in particular in terms of the reduction of the large reactivity swing and enhancement of the small Doppler coefficient typical of fertile-free actinide burners. Reduced electricity production cost is pursued through a longer cycle length than that used for fertile-free burners and thus a higher capacity factor. It is shown that the concept can achieve a high transuranics destruction rate, which is only 20% lower than that of an accelerator-driven system with fertile-free fuel. The small negative fuel temperature reactivity coefficient, small positive coolant temperature reactivity coefficient, and negative core radial expansion coefficient provide self-regulating characteristics so that the reactor is capable of inherent shutdown during major transients without scram, as in the Integral Fast Reactor. This is confirmed by thermal-hydraulic analysis of several transients without scram, including primary coolant pump trip, station blackout, and reactivity step insertion, which showed that the reactor was able to meet all identified thermal limits. However, the benefits of high actinide consumption and small reactivity swing can be attained only if the uranium from the discharged fuel is separated and not recycled. This additional uranium separation step and thorium reprocessing significantly increase the fuel cycle costs. Because the higher fuel cycle cost has a larger impact on the overall cost of electricity than the savings from the higher capacity factor afforded through use of thorium, this concept appears less promising than the fertile-free actinide burners

Psychoanalysis in modern mental health practice.

Yakeley, Jessica

2018-05-01

Like any discipline, psychoanalysis has evolved considerably since its inception by Freud over a century ago, and a multitude of different psychoanalytic traditions and schools of theory and practice now exist. However, some of Freud's original ideas, such as the dynamic unconscious, a developmental approach, defence mechanisms, and transference and countertransference remain essential tenets of psychoanalytic thinking to this day. This Review outlines several areas within modern mental health practice in which contemporary adaptations and applications of these psychoanalytic concepts might offer helpful insights and improvements in patient care and management, and concludes with an overview of evidence-based psychoanalytically informed treatments and the links between psychoanalysis, attachment research, and neuroscience.

[Ethical relativism and the modern concept of tolerance].

Science.gov (United States)

Laffitte, Jean

2008-01-01

History presents many examples of men and women who find themselves in a position of having to disobey civil law. The motives for such disobedience can only be founded on moral conscience, as influenced by other laws - immutable and recognized as true. The author studies the historical context of the appearance, during the Age of the Enlightenment, of a new concept: tolerance. Ceasing to represent the expression of the classical practical virtue of prudence, ideological tolerance achieves the rank of theoretical virtue. Such a pretension has a political in essence but also innumerable ethical consequences. An ideologically tolerant society is created. The author develops this paradoxical thesis according to which an ideologically tolerant society is not prepared to tolerate the idea that there might exist a truth for which to search. Today, we see a secularization of conscientious objection concerning two particular themes: military service and matters connected with the protection of human life. Examining the paradigmatic example of abortion, the author demonstrates how society is no longer capable of reflecting peacefully upon the question of the status of the embryo, for fear of questioning the legislative choice concerning its legalization. Thus, society no longer has the capability of confronting challenges connected to practices that are detrimental to the dignity of human life, the essential criteria that would allow it to face these matters having been declared outside the confines of future reflection.

This text offers an extension to the traditional Kripke semantics for non-classical logics by adding the notion of reactivity. Reactive Kripke models change their accessibility relation as we progress in the evaluation process of formulas in the model. This feature makes the reactive Kripke semantics strictly stronger and more applicable than the traditional one. Here we investigate the properties and axiomatisations of this new and most effective semantics, and we offer a wide landscape of applications of the idea of reactivity. Applied topics include reactive automata, reactive grammars, rea

Reactivity and Power Distribution Management in LEU-loaded Linear B and BR

International Nuclear Information System (INIS)

Hartanto, Donny; Kim, Yonghee

2013-01-01

In this paper, the relatively high excess reactivity issue during the initial transitional period was addressed. The design target is to achieve a maximum excess reactivity of about 1.0 dollar to prevent the possibility of the prompt jump critical accident. The initial core is divided into 2 radial Zr-zones in order to reduce the excess reactivity. By doing this, the power profile at the BOC can also be flattened. After the optimum initial core configuration has been found, the blanket region is also divided into 2 radial Zr-zones in order to flatten the power distribution at EOC. The neutronic analyses were all performed using the Monte Carlo code McCARD with ENDF-B/VII.0 library. It was found that by using the concave Zr-zoning in the initial core of B and BR, the maximum excess reactivity can be effectively lowered. The radial power profile can also be successfully flattened by using the Zr-zoning and concave initial core. The concave concept deserves more investigations for better performances of the B and BR core

Full Text Available Biomimetics, the art and science of imitating nature and life for technological solutions is discussed from a modern organization theory perspective. The main hypothesis of this article is that there are common laws in nature that are applicable to living, social and likewise organizational systems. To take advantage of these laws, the study of nature’s principles for their application to organizations is proposed – a process which is in product and technology design known as bionic creativity engineering. In a search for most interesting concepts borrowed from nature we found amoeba organizations, the theory of autopoiesis or self-creation, neural networks, heterarchies, as well as fractals and bioteaming which are described and reviewed. Additionally other concepts like swarm intelligence, stigmergy, as well as genesis and reproduction, are introduced. In the end all these ideas are summarized and guidelines for further research are given.

Qadar in Classical and Modern Islamic Discourses: Commending a Futuristic Perspective

Directory of Open Access Journals (Sweden)

WAN FARIZA ALYATI WAN ZAKARIA

2015-06-01

Full Text Available In classical Islamic era, the discussion on the concept of fate (divine predestination or qadar has created various debates with regard to its relationship to the problem of freedom (hurriya, choice (ikhtiyar and free will (irada. The word qadar has been treated differently by various Islamic thinkers such as the jurists, the Sufis, the philosophers and the theologians (mutakkalimun according to their respective concern. Classical discourse on qadar is found predominantly in debates between two main sects, the Murji’ites and the Jabarites who believe that God had predetermined the human life at one hand, and the others, the Muktazilites and the Qadarites who believe in human’s free will. The modern discourse on qadar shifts to different tunes. It is believed that qadar was responsible for paralyzing the energies of the Muslims and was the chief cause of their moral degeneration. The doctrine of qadar causes the Muslims to regard all their actions and achievements as dependent on the will of God and, for the same reason, they were unable to safeguard their rights and protect their countries from tyranny – thus obstructing their overall progress. This paper attempts at discussing both the classical and modern Islamic conceptions of qadar and its dynamism as the source of strength for Muslims to think about the future in positive attitude - that it is the only space which they could actively participate and operate in order to choose their destiny, be it good or bad, whether on the earth as God’s servants and vicegerents, as well as in the hereafter where they will taste the consequences of their actions. Understanding the true concept of qadar and also its dynamic association with the organic concept of time is about knowing the consequences of human actions and this is the very basic of futures thinking in Muslim mind.

[Constructing climate. From classical climatology to modern climate research].

Science.gov (United States)

Heymann, Matthias

2009-01-01

Both climate researchers and historians of climate science have conceived climate as a stable and well defined category. This article argues that such a conception is flawed. In the course of the 19th and 20th century the very concept of climate changed considerably. Scientists came up with different definitions and concepts of climate, which implied different understandings, interests, and research approaches. Understanding climate shifted from a timeless, spatial concept at the end of the 19th century to a spaceless, temporal concept at the end of the 20th. Climatologists in the 19th and early 20th centuries considered climate as a set of atmospheric characteristics associated with specific places or regions. In this context, while the weather was subject to change, climate remained largely stable. Of particular interest was the impact of climate on human beings and the environment. In modern climate research at the close of the 20th century, the concept of climate lost its temporal stability. Instead, climate change has become a core feature of the understanding of climate and a focus of research interests. Climate has also lost its immediate association with specific geographical places and become global. The interest is now focused on the impact of human beings on climate. The paper attempts to investigate these conceptual shifts and their origins and impacts in order to provide a more comprehensive perspective on the history of climate research.

Full Text Available The essay offers an Atlantic reading of Thomas Hobbes’ Leviathan and John Locke’s Second Treatise of Government based on the spatial concepts of “Land” and “Sea”. «Land» is considered as the spatial principle of a terracentric conception of politics, in which politics is viewed as static, and order exists only when conflict is neutralized. «Sea», on the contrary, is the spatial principle of a maritime conception of politics, in which politics is viewed as fluid, and order is shaped in an endless, changing, and conflicting movement of powers and agents. From this perspective, modern sovereignty emerges as a process of reterritorialization of  politics.

Modern imaging technology for childhood urinary tract infection

International Nuclear Information System (INIS)

Riccabona, M.; Fotter, R.

2005-01-01

Imaging in childhood urinary tract infection (UTI) is still a matter of debate. There are established guidelines, however new knowledge and the changed medical environment have enhanced this ongoing discussion. These new insights have impacted therapy and consequently the imaging algorithm. Modern imaging methods - particularly MRI and modern ultrasound (US) - are less invasive with a lower radiation burden. Additionally, it has been shown that VUR is a poor predictor for renal scarring out, which affects long-term results. Furthermore, the majority of UT malformations is depicted by prenatal US. The most crucial aspect of improving long-term outcome appears to be the early and reliable depiction of UTI and effective treatment to prevent renal scarring. This review tries to present this new knowledge and to discuss the potential of modern imaging. Recent changes in imaging algorithms are highlighted and an outcome-oriented algorithm that addresses these recent developments is proposed, without lightly abandoning established standards. It consists of an orienting US and - for depiction of renal involvement - amplitude coded color Doppler sonography or renal static scintigraphy (considered the gold standard, particularly for evaluating scars); in future MRI may play a role. Based on this concept, only patients with renal damage as well as patients with complex urinary tract malformations or intractable recurrent UTI may have to undergo VCUG. (orig.) [de

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.

The concept of modern control centre technology is shown, its realization at project including the supervision of an electric power distribution system is described. A modern control centre is characterized by the fact that the conventional control elements are more and more replaced by elements of computer technology, i.e. computer and displays. The different functions implemented by hard- and software set new standards relative to flexibility, adaptability, dimensioning. The communication interface man/process is defined and designed in a new way allowing dynamic and more efficent supervisionstrategy of technical processes via display in different operation modes. Special attention is paid to adjustments and extensions of process elements and their integration into the supervised network. (orig./WB) [de

Full Text Available The last few decades have seen the rise of ‘ecological modernization theory’ (EMT as a “green capitalist” tradition extending modernization theory into environmental sociology. This article uses a synthesis of political economy, world-systems theory, and political, economic, and environmental sociology to demonstrate that the EMT presumption of growth and profit as economic priorities (alongside its neglect of core-periphery relations produces many feedback loops which fatally undermine the viability of EMT’s own political, technological, and social prescriptions, alongside creating problems for the fundamental EMT concept of ‘ecological rationality.’ Furthermore, this article attempts to explain why “green capitalist” approaches to environmental analysis have influence within policy and social science circles despite their inadequacies within environmental sociology. Finally, this article argues that in order to address the ecological challenges of our era, environmental sociology needs to reject “green capitalist” traditions like ‘ecological modernization theory’ which presuppose the desirability and maintenance of profit and growth as economic priorities (and predominantly fail to critique power imbalances between core and non-core nations, and instead return to the development of traditions willing to critique the fundamental traits of the capitalist world-system.

Full Text Available The active publics issue and the question of the construction of publics are relatively recent in communication studies. After an initial period, when mass communication was seen as aiming at a holistic public, massified and passive and, thus, supposedly influenced via "targeted" messages, now the views on what "publics" mean is becoming diversified and nuanced under the influence of literary theories, cultural studies and what was later called "reception studies". Thus, from the "mass public" we got to the concept of "publics". However, in some recent studies, the mere existence of these publics is being questioned.In this paper, we detail the history of theories on the "public" - from the perspective of the public-as-spectator which later became public-as-audience and public-as-actor - and we set ourselves to show how, from theories on the re-active publics, we arrived, through the transformation of television and the emergence of the new IT&C, to the concept of publics as pro-active as a result of media efforts to build this activism.

India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality.

A modern approach to relay co-ordination that takes advantage of the improved performance of modern protective relays and circuits was proposed. The proposed method dealt with a mixture of new and old equipment and was most useful when implemented using common spreadsheet software. The suggested approach justified reduced time margins for relay co-ordination in many difficult applications. Other established approaches were reviewed. A discussion of fixed and variable time margin allowances was presented. The formulation of an equation to determine the required upstream relay operating time was explained, with sample calculations. Relay performance standards and modern protective equipment were discussed. It was concluded that modern relays and circuit breakers are much more advanced than designs of the recent past. The method described allowed significant reductions in margins which enabled modern relays to operate faster. While calculations for the procedures were said to be tedious to perform by hand, they can be easily done with spreadsheet software. 10 refs., 4 figs.

The unique role of halogen substituents in the design of modern agrochemicals.

Science.gov (United States)

Jeschke, Peter

2010-01-01

The past 30 years have witnessed a period of significant expansion in the use of halogenated compounds in the field of agrochemical research and development. The introduction of halogens into active ingredients has become an important concept in the quest for a modern agrochemical with optimal efficacy, environmental safety, user friendliness and economic viability. Outstanding progress has been made, especially in synthetic methods for particular halogen-substituted key intermediates that were previously prohibitively expensive. Interestingly, there has been a rise in the number of commercial products containing 'mixed' halogens, e.g. one or more fluorine, chlorine, bromine or iodine atoms in addition to one or more further halogen atoms. Extrapolation of the current trend indicates that a definite growth is to be expected in fluorine-substituted agrochemicals throughout the twenty-first century. A number of these recently developed agrochemical candidates containing halogen substituents represent novel classes of chemical compounds with new modes of action. However, the complex structure-activity relationships associated with biologically active molecules mean that the introduction of halogens can lead to either an increase or a decrease in the efficacy of a compound, depending on its changed mode of action, physicochemical properties, target interaction or metabolic susceptibility and transformation. In spite of modern design concepts, it is still difficult to predict the sites in a molecule at which halogen substitution will result in optimal desired effects. This review describes comprehensively the successful utilisation of halogens and their unique role in the design of modern agrochemicals, exemplified by various commercial products from Bayer CropScience coming from different agrochemical areas.

Avant-garde: The Convulsions of a Concept

Full Text Available The current status of the «avant-garde» provokes many questions, which include both inner-artistic matters and matters of history and society commonly associated with Marxist or reception-oriented thinkers. The convolution of questions cannot be disentangled; efforts to confront the dilemmas of the avant-garde cannot abstract from matters of commodification, recent reception, or the complex dialectic of «classical» and «modern.» The essay deals with the most recent manifestations of avant-garde aesthetic impulses. It emphasizes the historical and social aspects of German theorizing in contrast to purely formalist or ahistorical conceptions commonly found elsewhere. It insists that such «materialist» theory does greater justice than formalist conceptualizations to the proverbial connections of «art» and «life.» It tries to integrate the present phenomenon of proliferating theory into the theoretical exposition, as a characteristic trait of the current situation. It warns against abandoning the subversive content of classical modernism in the course of developing a theory of post-modernism.

Jackson, Todd, and the concept of "discharge" in epilepsy.

To explore the historical origins of the modern concept of electrical discharges in the brain in epilepsy. I have examined the writings of Hughlings Jackson (1835-1911) and Robert Bentley Todd (1809-1860), especially their Lumleian Lectures on convulsive disorders to the Royal College of Physicians of 1890 and 1849, respectively; and also the influence of Herbert Spencer (1820-1903) on the former and Michael Faraday (1791-1867) on the latter. Contrary to the widely taught view that Jackson was the first to propose electrical discharges in epilepsy it is clear that the discharges suggested by Jackson, influenced by the evolutionary philosopher, Herbert Spencer, were chemical, based on katabolism and anabolism. Jackson had no understanding or proposal based on physics or electricity. On the other hand, Todd had earlier proposed and described electrical concepts of discharges in epilepsy, influenced by his contemporary and colleague in London, Michael Faraday, who at the time was laying the foundations of our modern understanding of electricity and magnetism. Todd and Faraday saw "nervous polarity" as another polar force interchangeable with the polar forces of electricity and magnetism.

Highlights: • The graphite rod-inserted SFR fuel assembly is proposed to achieve low sodium void reactivity. • The neutronics/thermal-hydraulics analyses are performed for the proposed SFR cores. • The sodium void reactivity is improved about 960–1030 pcm compared to reference design. - Abstract: The concept of a graphite-moderating rod-inserted sodium-cooled fast reactor (SFR) fuel assembly is proposed in this study to achieve a low sodium void reactivity coefficient. Using this concept, two types of SFR cores are analyzed; the proposed SFR type 1 core has new SFR fuel assemblies at the inner/mid core regions while the proposed SFR type 2 core has a B{sub 4}C absorber sandwich in the middle of the active core region as well as new SFR fuel assemblies at the inner/mid core regions. For the proposed SFR core designs, neutronics and thermal-hydraulic analyses are performed using the DIF3D, REBUS3, and the MATRA-LMR codes. In the neutronics analysis, the sodium void reactivity coefficient is obtained in various void situations. The two types of proposed core designs reduce the sodium void reactivity coefficient by about 960–1030 pcm compared to the reference design. However, the TRU enrichment for the proposed SFR core designs is increased. In the thermal hydraulic analysis, the temperature distributions are calculated for the two types of proposed core designs and the mass flow rate is optimized to satisfy the design constraints for the highest power generating assembly. The results of this study indicate that the proposed SFR assembly design concept, which adopts graphite-moderating rods which are inserted into the fuel assembly, can feasibly minimize the sodium void reactivity coefficient. Single TRU enrichment and an identical fuel slug diameter throughout the SFR core are also achieved because the radial power peak can be flattened by varying the number of moderating rods in each core region.

Nowadays, various digital methods making use of microcomputers for neutron detector signals and determining the reactivity by numerical calculations are used in reactor control systems in place of classical reactivity meters. In this work, a calculation based on the ''The Time Dependent Transport Equation'' has been developed for determining the reactivity numerically. The reactivity values have been obtained utilizing a computer-based data acquisition and control system and compared with the analog reactivity meter values as well as the values calculated from the ''Inhour Equation''

Formalization and Interaction: Toward a Comprehensive History of Technology-Related Knowledge in Early Modern Europe.

Popplow, Marcus

2015-12-01

Recent critical approaches to what has conventionally been described as "scientific" and "technical" knowledge in early modern Europe have provided a wealth of new insights. So far, the various analytical concepts suggested by these studies have not yet been comprehensively discussed. The present essay argues that such comprehensive approaches might prove of special value for long-term and cross-cultural reflections on technology-related knowledge. As heuristic tools, the notions of "formalization" and "interaction" are proposed as part of alternative narratives to those highlighting the emergence of "science" as the most relevant development for technology-related knowledge in early modern Europe.

In comparison to the use of rodent models, the use of fish as a potential model to predict immune dysfunction in response to environmental contaminants is a relatively new concept. The development of a fish model for immunotoxicity is possible due to the phylogenetic conservation of many immune functions. The authors have compared mononuclear cell reactivity following in vitro stimulation among five species; Japanese medaka (Oryzias latipes), rainbow trout (Oncorhynchus mykiss), DBA/2 mice, Sprague-Dawley rats and human ML-1 cells. Mononuclear cells were isolated from the rodent bone marrow and from the teleost anterior kidney (the cell population which most closely resembles mammalian hematopoietic tissue). ML-1 cells are a myeloblastic cell line that were differentiated in vitro to monocytes/macrophages. Cell populations were characterized by myeloperoxidase and nonspecific esterase staining characteristic. Reactive oxidant production following in vitro stimulation by phorbol ester was measured using the following methods: reduction of cytochrome c (detection of extracellular superoxide), reduction of nitroblue tetrazolium (detection of intracellular superoxide) and oxidation of phenol red in the presence of horseradish peroxidase (hydrogen peroxide production). In general, teleost cells demonstrated higher superoxide anion production and mammalian cells produced higher quantities of hydrogen peroxide.

Full Text Available In a reparative history Dana Simmons boldly faces self feelings of imposture and guilt and engages them to consider how science studies can move beyond critical appraisals to undertake the greater, more important task of reassembling the self and studies of the self. For readers who are aware of their psychologized self-conceptions, her history promises opportunities for re-appraisal and re-assemblage. This commentary appreciates Simmons’ illumination of the race, class, and gender constituents of the psychologies of achievement which, among their products, have yielded the very idea of Impostor Syndrome. Further development of the kind of reparative histories advocated by Simmons demands attention to the enormity of our psychologized modernity and the complexities of reflexive psychology.

Ancient Indian mental concepts of children and adolescents are very similar to the contemporary modern concepts. The ancient concepts were based on a very positive regard for the children's development, education and future independence, adult role and contribution to society. Children were wanted and considered precious. The children were categorized in to 4 different varnas based on their intelligence, abilities, merit and aptitude and educated accordingly, away from their home, at Gurukuls. They had universal right to education. Girls received attention equal to boys. The boys were expected to earn their livelihood, while the girls were expected to be homemakers. Graduation of the young person at the end of education and return to home marked the emancipation from adolescence. Children's physical and mental health and its disorders were given due attention. Aetiology and treatment of physical and mental disorders was in accordance with the overall scientific development of those times.

Full Text Available Thesis objective is to study modern methods of product supply with the purpose to determine optimal ways for their rationalization. Since the use of reasonable practices, taking into account external and internal factors under the specific conditions of product moving from the supplier to the buyer, makes the process of product supply economically viable, i.e., low costs for product transportation, ensures fast moving products, their safety and, ultimately, results in reduction of the costs of product disposal. Methodology. The study is based on theoretical methods to study this problem. System analysis method and simulation of the ways to improve were also used in the study. Results. Addressing these issues, the concept, form and stages of product supply process organization depending on the type of product have been studied; product supply management methods based on logistics concept of “demand response”. Practical significance. Optimization of the principles and methods of product supply, factors affecting its organization will, in practice, contribute to the development of reasonable product delivery systems featured with economic efficiency of advanced technologies of product supply. Value/ originality. The analyzed methods of product supply management based on logistics concept of “demand response” can ensure maximum reduction of response time to the changes in demand by rapid stocktaking at those points of the market where the demand is expected to increase, which will allow to reduce the costs of bringing the product to the consumer.

The APA concept was developed with the aim of increasing the PWR capacity to burn plutonium emerging from the recycling of irradiated fuels in the French park of nuclear power plants. At first, a concept using annular pins was optimised to allow a good consumption of plutonium while preserving an acceptable neutron control. To cope with the technological problems and those posed by the manufacture of these annular pins, an alternative concept is presented here. It poses as initial conditions the conservation of both the plutonium balance and the respect of the reactivity control. (authors)

Zelfregulering als een vernieuwend concept van professionaliteit

Gerard Donkers

2014-03-01

Full Text Available Self-regulation as an innovative concept of professionalismThis contribution opens with a discussion of three sources of knowledge that form a foundation for the concept of “selfregulation” as developed by Donkers. It starts with a historical enquiry on the Western European ideas about change and changeability of people and society. Three paradigms of change appear which in every period of modern history conflicted with each other and thereby became refined and differentiated. A second source relates to practice research to a number of methods for social intervention. The third source is a critical reflection on contemporary societal developments. Central in that reflection are all kinds of expropriation of self-direction – in – dialogue with others and processes of fragmentation of the complex societal reality. From these three sources a plea is given for a new concept of professionalism marked by strong attention for the reinforcement of the selfregulating possibilities of persons, organizations and society.In the second part Geertsema focusses on the relation between change and intervention and values that are part of these processes. As the Dutch society seems to be in a third order transition, without a clear view of the new situation, the urgency of value debates is high. But the late modernity seems to be imprisoned in notions of individuality that puts strong pressure upon more relational ontologies and mutual responsibilities. Besides that growing anonymous and invisible systems influence the formation of daily life deeply. If there will be a situation of relational ontology which make use of the powers of diversity and multiplicity of our existence, then change agents should take a moral stance by themselves to create space for numerous narratives. The concept of “selfregulation” makes it possible to relate these value debates with debates about the design of society in this transition situation.Zelfregulering als een

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.

Ontological And Anthropological Aspects of the Concept of Human Nature

2011-12-01

Full Text Available Anthropology is the study of the origin of the man. It is basically concern with the concept of Homo sapiens, and it is scientifically questioning what are human physical traits as well how do men behave and the variation among different groups of  human with his social and cultural dimensions. Ontology is a subfield in traditional philosophy which is mainly focuses on the nature of being, existence or reality as such. There are some similarities and differences among these two areas. However when we deeply study the philosophical basis of the anthropology it is proof that it was derived from ontology.Anthropology discusses the social and cultural world or the physical entity of human nature. Ontology focuses the invisible aspect of human nature along with the ultimate reality. Therefore, it has a metaphysical aspect of human being; this philosophical notion has in fact, contributed to the development of the subject of anthropology. The present modern day has given very little attention to this philosophical combination of  ontolog y to anthropology, rendering further investigation into the philosophical roots of anthropology.This research paper seeks to evaluate the relationship between ontology and anthropology by paying attention to the ontological arguments about the concept of man and human nature within Greek and modern western thoughts, in comparing with modern anthropological arguments.

2008-06-01

Full Text Available This article seeks to analyze, briefly, how the conception of the religious truth of Pernambuco’s kardecists, based in the modern science canons, justifies between them the development of difficult relationships with the followers of the other religions, in a time that the Catholic religion hegemony is being broken, making a plural religious situation. That way, methodologically, we tried to accomplish the exposition in a way that it was possible to intersect a discussion about the construction of the modern identity’s concept that didn’t take in consideration the difference of the Other, to a discussion on the understanding that the tolerance also had in the modernity, starting from an Eurocentric perspective. In the end, we articulate identity concepts of truth and tolerance, elaborated in the modernity time, to the spiritualistic practice, observing that this practice, when being influenced by those definitions, revealed itself very difficult on the part of the kardecists to know how to treat with respect other religious difference.

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.

A combination ofperiodontitis and pulp or periapical tissues inflammation in one tooth is known as endo-periodontal lesions. Such kind of lesion is serious problem of modern dentistry. It was found that pathogenic microflora of periodontal pocket and root canal of tooth with eno-perio lesion is almost the equal and consist of anaerobic microorganisms. Pathogenic effects have not only microorganisms but also their life products. Apical foramen, lateral and additional canals are physiological ways for pathogens migration. Inflammatory processes in these structures complicate each other. Lack of information among dentists about treatment possibilities of endo-perio lesions is a main reasons of extraction such kind of teeth. Simultaneous elimination of pathogens both from periodontal pocket and root canal is a key factor for effective treatment. Periodontal status is main factor for prognosis of tooth with endo-perio lesion, because of it treatment of endo-perio lesions should consist of two stages: infection elimination and regeneration of tooth-supported structures.

How do we represent the meaning of words? The present study assesses whether access to conceptual knowledge requires the reenactment of the sensory components of a concept. The reenactment-that is, simulation-was tested in a word categorisation task using an innovative masking paradigm. We hypothesised that a meaningless reactivated visual mask should interfere with the simulation of the visual dimension of concrete words. This assumption was tested in a paradigm in which participants were not aware of the link between the visual mask and the words to be processed. In the first phase, participants created a tone-visual mask or tone-control stimulus association. In the test phase, they categorised words that were presented with 1 of the tones. Results showed that words were processed more slowly when they were presented with the reactivated mask. This interference effect was only correlated with and explained by the value of the visual perceptual strength of the words (i.e., our experience with the visual dimensions associated with concepts) and not with other characteristics. We interpret these findings in terms of word access, which may involve the simulation of sensory features associated with the concept, even if participants were not explicitly required to access visual properties.

Preliminary concept of a zero power nuclear reactor core

International Nuclear Information System (INIS)

Mai, Luiz Antonio; Siqueira, Paulo de Tarso D.

2011-01-01

The purpose of this work is to define a zero power core to study the neutronic behavior of a modern research reactor as the future RMB (Brazilian Nuclear Multipurpose reactor). The platform used was the IPEN/MB-01 nuclear reactor, installed at the Nuclear and Energy Research Institute (IPEN-CNEN/SP). Equilibrium among minimal changes in the current reactor facilities and an arrangement that will be as representative as possible of a future core were taken into account. The active parts of the elements (fuel and control/safety) were determined to be exactly equal the elements of a future reactor. After several technical discussions, a basic configuration for the zero power core was defined. This reactor will validate the neutronic calculations and will allow the execution of countless future experiments aiming a real core. Of all possible alternative configurations for the zero power core representative of a future reactor - named ZPC-MRR (Zero Power Core - Modern Research Reactor), it was concluded, through technical and practical arguments, that the core will have an array of 4 x 5 positions, with 19 fuel elements, identical in its active part to a standard MTR (Material Test Reactor), 4 control/safety elements having a unique flat surface and a central position of irradiation. The specifications of the fuel elements (FEs) are the same as defined to standard MTR in its active part, but the inferior nozzles are differentiated because ZPC-MRR will be a set without heat generation. A study of reactivity was performed using MCNP code, and it was estimated that it will have around 2700 pcm reactivity excess in its 19 FEs configuration (alike the present IPEN/MB-01 reactivity). The effective change in the IPEN/MB-01 reactor will be made only in the control rods drive mechanism. It will be necessary to modify the center of this mechanism. Major modifications in the facility will not be necessary. (author)

A reactivity hold-down strategy for soluble boron free operation by introducing Pu-238 added fuel

International Nuclear Information System (INIS)

Kim, Soon Young; Kim, Jong Kyung

2000-01-01

A new concept of Pu-238 added fuel is introduced to control the reactivity and power distribution in soluble boron free (SBF) pressurized water reactor (PWR) core. Though extensive use of burnable poison and control rods is inevitable for reactivity suppression in SBF core, it causes the core power distribution control to be so difficult that a practical SBF operation is far distant. In this work, it is confirmed that the excess reactivity can be greatly suppressed by introducing the Pu-238 added fuel. As a result of the conceptual core design of the 600 MWe SBF PWR using Pu-238 added fuel, the core reactivity is well controlled in comparison with the results obtained from the earlier 600 MWe SBF core design works. Especially, the axial power shape control is performed successfully with the aid of simple axial zoning scheme, developed in this study, by using Pu-238 enrichment zoning. The Pu-238 added fuel is also tested for 1300 MWe SBF PWR core design, in which the power distribution control can be more difficult than that of smaller plants if soluble boron control is not available. The results show that the core excess reactivity and the power distribution can be well controlled without using soluble boron even in a large-sized PWR. Hence, one of the difficult control problems arising in SBF core design can be greatly mitigated by introducing the new fuel concept. It is further expected that the Pu-238 added fuel, the simple axial zoning scheme, and the control bank operation strategy introduced in this study are directly applicable to practical SBF core design

Sensitivity of reactivity feedback due to core bowing in a metallic-fueled core

International Nuclear Information System (INIS)

Nakagawa, Masatoshi; Kawashima, Masatoshi; Endo, Hiroshi; Nishimura, Tomohiro

1991-01-01

A sensitivity study has been carried out on negative reactivity feedback caused by core bowing to assess the potential effectiveness of FBR passive safety features in regard to withstanding an anticipated transient without scram (ATWS). In the present study, an analysis has been carried to obtain the best material and geometrical conditions concerning the core restraint system out for several power to flow rates (P/F), up to 2.0 for a 300 MWe metallic-fueled core. From this study, it was clarified that the pad stiffness at an above core loading pads (ACLP) needs to be large enough to ensure negative reactivity feedback against ATWS. It was also clarified that there is an upper limit for the clearances between ducts at ACLP. A new concept, in regard to increasing the absolute value for negative reactivity feedback due to core bowing at ATWS, is proposed and discussed. (author)

A study has been performed on the passive safety features and technical feasibility of an inherently safe 60 MWe fast reactor concept RAPID to meet various power requirements in Japan. The system dynamic analyses on the UTOP and ULOF transients revealed that the enhanced reactivity feedback derived from an annular core configuration and the integrated fuel assembly provides a high margin of self-protection. Structural integrity of the integrated fuel assembly has also been confirmed. The following innovative key technologies have been demonstrated; Lithium Injection Modules (LIM) for ultimate shutdown, Lithium Expansion Modulus (LEM) for inherent reactivity feedback and Void Leading Channel (VLC) for the sodium void worth reduction.

Finotti, Claudio; Gaio, Elena; Song, Inho; Tao, Jun; Benfatto, Ivone

2015-01-01

Highlights: • The slow response reasons of the classic ITER Reactive Power Compensation (RPC) control are explained. • The dynamic behaviors of the ac/dc converter and of the RPC are characterized. • New control concept to speed up the RPC response is developed. • Good performance of the new RPC control is verified even during fast transient conditions. - Abstract: The ITER ac/dc conversion system can absorb a total active and reactive power up to 500 MW and 950 Mvar, respectively. The Reactive Power Compensation (RPC) system is rated for a nominal power of 750 Mvar necessary to comply with the allowable reactive power limit value from the grid of 200 Mvar. This system is currently under construction and is based on Static Var Compensation technology with Thyristor Controlled Reactor (TCR) and Tuned Filters. The RPC has to minimize the demand of reactive power from the grid; its control is based on a feed-forward method, where the corrective input is the measurement of the reactive power consumption of the ac/dc converters, derived from the 50 Hz component of the Fast Fourier Transform (FFT) of the three-phase voltages and currents. The delay introduced by the FFT calculation and the slow response of the TCR could make the response speed of the RPC not sufficient to face fast variations of the reactive power demand and therefore in this paper a new controller of the RPC able to overcome this shortcoming is proposed and evaluated. It is based on the calculation of the predicted consumption of the reactive power by using the voltage reference signals coming from the Plasma Control System and the measurements of the dc current of the ac/dc converters and of the 66 kV busbar voltage, and on the speed up of the RPC control by introducing a lead–lag transfer function.

THE PHILOSOPHICAL FOUNDATIONS OF MODERN BIOENGINEERING

Directory of Open Access Journals (Sweden)

Ibrahim A. Shogar

2017-12-01

Full Text Available This paper investigates the philosophical foundations of modern bioengineering to articulate its ethical framework. Engineering as an ultimate mechanism to transform knowledge into practice is essential for both physical and biological sciences. It reduces data, concepts, and designs to pictorial forms. The integration of engineering with the newly emerging biosciences, has presented a unique opportunity to overcome the major challenges that face the environmental and human health. To harness potentials of bioengineering and establish a sustainable foundation for green technology, modern scientists and engineers need to be acquainted with the normative questions of science. In addition to acquiring the general principles of scientific research and identifying the intrinsic goals of the endeavour, philosophy of bioengineering exposes bioengineers to both the descriptive ‘how’ questions of the physical world as well as the normative ‘why’ questions of values. Such an interdisciplinary approach is significant, not only for inspiring to acquire the genuine knowledge of the existing world, but also to expose the bioengineers to their ethical and social responsibilities. Besides introducing the conceptual framework of bioengineering, this paper has investigated the three major philosophies that have been dominating the theoretical presuppositions of scientific research method in history. Namely, (i Systems biology approach; (ii Evolutionary biology approach; and (iii Mechanical view approach. To establish the ethical foundation of modern bioengineering, the paper, also has conducted an analytical study on various branches of the emerging discipline of bioscience. The paper has concluded that adopting the interdisciplinary approach in research and education is essential to harness potentials of bioengineering and to establish foundations of green technology. To achieve the final objectives of bioengineering, both the practical and theoretical

Comparison between worker-deaths in modern industries and in nuclear activities

International Nuclear Information System (INIS)

Failla, L.

1977-01-01

The statistical data related to the deaths of workers in modern industries, are examined. This analysis regards deaths by accident. It regards some particular countries in the world; these particular countries have been selected because their data are comparable. The analysis in modern industry regards different years. For the worker deaths caused by professional diseases, some particular considerations are made. Due to the fact that international statistics for worker deaths due to professional diseases don't exist, it was necessary to resort to the existing corollation between professional diseases and accidents in industry, to extrapolate, with some approximation, the number of deaths due to professional disease. Using these considerations it is possible to find some interesting data. The statistics are examined in order to compare them with those pertinent to nuclear energy. With regard to this topic, the mortal-risks from radiation exposures are considered. The philosophies used in modern industry and in the nuclear energy field, are compared. A special discussion is carried on about ICRP conception, expressed in Publication 22: 'Implications of Commission Recommendations that Doses be kept as Low as Readily Achievable'

Modern concepts for basic radiobiological factors characterizing tumor tissue radiosensitivity

International Nuclear Information System (INIS)

Gocheva, L.; Sergieva, K.

2002-01-01

Traditionally radiotherapy is prescribed at doses consistent with the expected therapeutic response and tolerance of tumor and normal tissues without consideration to individual differences in radiosensitivity. However, the basic radiobiological knowledge and clinical experience along this line point to significant variations in the observed therapeutic results. It has been established that cells and tissues under experimental and clinical conditions manifest a wide spectrum of individual radiosensitivity. The aim of this survey is to outline the current concepts for the basic radiobiological factors influencing tumor radiosensitivity. A thorough discussion is done of the essence, mechanisms of action, methods of determination and measurement, and effect on the prognosis in patients with malignant diseases of a number of radiobiological factors, such as: tumor-cell proliferation, apoptosis, tumor hypoxia and neovascularization. Although the knowledge of the mechanisms of radiosensitivity is constantly expanding, its clinical implementation is still rather limited. The true role of radiosensitivity in predicting the therapeutic response should be more accurately defined. (authors)

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.

Full Text Available One way to improve students’ chemistry literacy which is demanded in the modernization of modern technology-based chemistry learning is by studying ionic liquids. Low level of scientific literacy of students in Indonesia as revealed in the PISA in 2012 was the main reason of the research. Ionic liquids-based technology are necessary to be applied as a context for learning chemistry because: (1 the attention of the scientific an technology community in the use of ionic liquids as a new generation of green solvent, electrolyte material and fluidic engineering in recent years becomes larger, in line with the strong demands of the industry for the provision of new materials that are reliable, safe, and friendly for various purposes; (2 scientific explanations related to the context of the ionic liquid contains a lot of facts, concepts, principles, laws, models and theories can be used to reinforce the learning content as a media to develop thinking skill (process/competence as demanded by PISA; (3 The modern technology-based ionic liquid can also be used as a discourse to strengthen scientific attitude. The process of synthesis of ionic liquid involves fairly simple organic reagents, so it deserves to be included in the chemistry subject in school.

Delocalization model of regioselectivity and reactivity of free radicals in reactions of addition to olefins

International Nuclear Information System (INIS)

Volovik, S.V.; Dyadyusha, G.G.; Staninets, V.I.

1987-01-01

On the basis of the concept of polarity (philicity) of free radicals as proposed by the authors, within the framework of methods of qualitative surfaces of potential energy (linear combinations of configurations of fragments) and stabilization energy, an effective model has been developed for the regioselectivity and reactivity of radicals in processes of addition. A critical examination is made of certain key aspects of the change in regiochemistry and reactivity with changes in the electronic structure of the free radical and substrate. The dominant trends in regioselectivity and reactivity in processes of free-radical addition to olefins are controlled by electronic effects and can be predicted by analyzing interactions of diabatic potential energy surfaces or orbital interactions for a system consisting of a free radical and an unsaturated substrate

Repetition and the Concept of Repetition

Directory of Open Access Journals (Sweden)

Arne Grøn

2013-11-01

Full Text Available This paper offers a description of the meaning of the category of repetition. Firstly, it is pointed out that Constantin uses repetition as a concept that means the creation of epochs; the passing from Greece to Modernity is accomplished distinguishing between recollection, a concept that looks back to the past, and repetition, a concept that looks forward to future. Secondly, it is showed that the category of repetition, as a religious category, relates with what Climacus calls “ethic despair” and with what Vigilius calls “second ethics”; it is through repetition that it can be understood that sin finds its place in ethics and these shows the tension between it and dogmatics. And thirdly, it is showed that the descovery of the new category of repetition is a rediscovery of what Kierkegaard calls category of spirit; repetition has for its object the individuality, and coming to be oneself is what Kierkegaard undertands as liberty. At the end of the paper it is questioned if the category of repetition is inconsistent with the book Repetition.

In conventional perturbed angular correlation (PAC)-spectroscopy huge amounts of events are processed by fast electronics. Modern digital signal processing devices and the improvement in the computer technology in recent years allow today digital PAC-spectrometer setups capable to perform software-based data processing with all the benefits of storage, repeatable data analysis under different limits, and easy switching between different isotopes. In this paper we discuss experiences and concepts of a first realized digital PAC-spectrometer, which will be rebuild at ISOLDE/CERN/Geneva.

Establishing a value chain for human factors in nuclear power plantcontrol room modernization

2015-07-01

Commercial nuclear power plants in the United States (U.S.) have operated reliably and efficiently for decades. With the life extensions of plants now being planned for operation beyond their original operating licenses, there are opportunities to achieve even greater efficiencies, while maintaining high operational reliabilities, with strategic, risk- and economically-informed, upgrades to plant systems and infrastructure. The U.S. Department of Energy’s Light Water Reactor Sustainability (LWRS) program supports the commercial nuclear industry’s modernization efforts through research and development (R&D) activities across many areas to help establish the technical and economic bases for modernization activities. The Advanced Instrumentation, Information, and Control Systems Technologies pathway is one R&D focus area for the LWRS program, and has researchers at Idaho National Laboratory working with select utility partners to use human factors and instrumentation and controls R&D to help modernize the plant’s main control room. However, some in the nuclear industry have not been as enthusiastic about using human factors R&D to inform life extension decision making. Part of the reason for this may stem from uncertainty decision-makers have regarding how human factors fits into the value chain for nuclear power plant control room modernization. This paper reviews past work that has attempted to demonstrate the value of human factors, and then describes the value chain concept, how it applies to control room modernization, and then makes a case for how and why human factors is an essential link in the modernization value chain.

Full Text Available Introduction. The relevance of the problem under study is caused by the contradiction between the necessity of fundamentalization of education, raising it to the level of the requirements of integral human development and the deepening disintegration of all sides of his life, including vocational education.The aim of the present publication is philosophical and pedagogical reflection and development of mechanisms for mainstreaming integrative-holistic approach when building a hypothetical model of professional education, aimed at provision of strategic turn towards more balanced (dialectical approach to the traditional values of education. In particular, it concerns the experience of mining schools of the Urals.Methodology and research methods. A leading approach to the study of this problem is an integrative-holistic approach (PPI that can identify the holistic nature of the pedagogical system in which: a inter-transformation of cooperated parts occurs not at the expense of each other, but on behalf of each other part; b the existence of common points of contact between the cooperated components is complemented by the coexistence of the opposite, sometimes mutually exclusive sides of life; c the idea of the priority of the whole is in harmony with the idea of polycentrism.Results and scientific novelty. The study shows the failure of the monopoly of the prevailing doctrine of competence-based education as a means for the successful resolution of global problems of reintegration of human existence and therefore postulated the necessity of antinomization (diversification of education. The authors make the original hypothesis of the construction of the concept of vocational education on the basis of the reconstruction of experience of the mining schools of the Urals and prove the prospectivity of integrative-holistic strategy of reconstruction of educational experience in modern conditions.

Full Text Available In present days there is a strong influence of the concept incorporating increased use of low intensive colours and small “digitalized” form structures for modern army camouflage designs. It was proclaimed as a revolutionary “universal” design line. It was supposed to be superior to others patterns designs and to be optimal for most types of environment. Meanwhile, some arm forces insist on developing more limited as terrain range camouflage design but with better efficiency and specialization. These two concepts in design reflect the political and the military philosophies of the countries they represent. However, at the end for the soldiers at the battlefield it is a matter of survival.

Full Text Available The relation between magic, religion and therapy in Nepal is analyzed here in the context of the widest process of medicalization which takes place at global level. The Nepalese indigenous system of diagnosis, treatment and healing has evolved evolved in a process of trial-and-error, empirical observation and experimental procedure. The article suggests that it is an on-going process not dissimilar to modern medicine. The concept of disease does not include the germ theory but rather the theory that the essence of the body has been captured by some external power. Task of the healer is to try to release the soul or balance the system establishing “normal” functions. The article provides the description of multiple roles related to the diagnostic process and gives ethnographic case-studies of the relation between traditional and modern medicine. Government and private agencies are described as working in the rural areas with the healers in order to use their clout to take the modern health-package to the most remote communities and to reduce the mortality rate.

This book proposes a new way of formalizing in logic and mathematics - a "pyramidal graph system," devised by the author and based on Porphyrian trees and modern concepts of classification, in both of which pyramids act as the organizing schema.

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."

Why did occidental modernity fail in the Arab Middle East: the failed modern state?

OpenAIRE

Sardar, Aziz

2011-01-01

This thesis asks a straightforward but nevertheless a complex question, that is: Why did modernity fail in the Arab Middle East? The notion of modernity in this thesis signifies the occidental modernity which reached the region in many different forms and through various channels. This occidental modernity had an impact on many areas and changed the societies and politics of the region. But these changes stopped short of reaching modernity, in other words it failed to change the society from ...

Nuclear reactors experience small power fluctuations or anticipated operational transients during even normal power operation. During normal operation, the reactivity is mainly controlled by liquid zone controllers, adjuster rods, mechanical control absorbers, and moderator poison. Even when the reactor power is increased abruptly and largely from an accident and when reactor control systems cannot be actuated quickly due to a fast transient, the reactor should be controlled and stabilized by its inherent safety parameter, such as a negative PCR (Power Coefficient of Reactivity) feedback. A PWR (Pressurized Water Reactor), it is well designed for the reactor to have a negative PCR so that the reactor can be safely shut down or stabilized whenever an abrupt reactivity insertion into the reactor core occurs or the reactor power is abruptly increased. However, it is known that a CANDU reactor has a small amount of PCR, as either negative or positive, because of the different design basis and safety concepts from a PWR. CNSC's regulatory and safety regime has stated that; The PCR of CANDU reactors does not pose a significant risk. Consistent with Canadian nuclear safety requirements, nuclear power plants must have an appropriate combination of inherent and engineered safety features incorporated into the design of the reactor safety and control systems. A reactor design that has a PCR is quite acceptable provided that the reactor is stable against power fluctuations, and that the probability and consequences of any potential accidents that would be aggravated by a positive reactivity feedback are maintained within CNSCprescribed limits. Recently, it was issued licensing the refurbished Wolsong unit 1 in Korea to be operated continuously after its design lifetime in which the calculated PCR was shown to have a small positive value by applying the recent physics code systems, which are composed of WIMS IST, DRAGON IST, and RFSP IST. These code systems were transferred

BN600 reactivity definition

International Nuclear Information System (INIS)

Zheltyshev, V.; Ivanov, A.

2000-01-01

Since 1980, the fast BN600 reactor with sodium coolant has been operated at Beloyarsk Nuclear Power Plant. The periodic monitoring of the reactivity modifications should be implemented in compliance with the standards and regulations applied in nuclear power engineering. The reactivity measurements are carried out in order to confirm the basic neutronic features of a BN600 reactor. The reactivity measurements are aimed to justify that nuclear safety is provided in course of the in-reactor installation of the experimental core components. Two reactivity meters are to be used on BN600 operation: 1. Digital on-line reactivity calculated under stationary reactor operation on power (approximation of the point-wise kinetics is applied). 2. Second reactivity meter used to define the reactor control rod operating components efficiency under reactor startup and take account of the changing efficiency of the sensor, however, this is more time-consumptive than the on-line reactivity meter. The application of two reactivity meters allows for the monitoring of the reactor reactivity under every operating mode. (authors)

Developing an instrument for assessing students' concepts of the nature of technology

Liou, Pey-Yan

2015-05-01

Background:The nature of technology has been rarely discussed despite the fact that technology plays an essential role in modern society. It is important to discuss students' concepts of the nature of technology, and further to advance their technological literacy and adaptation to modern society. There is a need to assess high school students' concepts of the nature of technology. Purpose:This study aims to engage in discourse on students' concepts of the nature of technology based on a proposed theoretical framework. Moreover, another goal is to develop an instrument for measuring students' concepts of the nature of technology. Sample:Four hundred and fifty-five high school students' perceptions of technology were qualitatively analyzed. Furthermore, 530 students' responses to a newly developed questionnaire were quantitatively analyzed in the final test. Design and method:First, content analysis was utilized to discuss and categorize students' statements regarding technology and its related issues. The Student Concepts of the Nature of Technology Questionnaire was developed based on the proposed theoretical framework and was supported by the students' qualitative data. Finally, exploratory factor analysis and reliability analysis were applied to determine the structure of the items and the internal consistency of each scale. Results:Through a process of instrument development, the Student Concepts of the Nature of Technology Questionnaire was shown to be a valid and reliable tool for measuring students' concepts of the nature of technology. This newly developed questionnaire is composed of 29 items in six scales, namely 'technology as artifacts,' 'technology as an innovation change,' 'the current role of technology in society,' 'technology as a double-edged sword,' 'technology as a science-based form,' and 'history of technology.' Conclusions:The Student Concepts of the Nature of Technology Questionnaire has been confirmed as a reasonably valid and reliable

A rod ejection accident may cause severer result in SMRs because SMRs have relatively high control rod reactivity worth compared with commercial nuclear reactors. Because this accident would be perfectly excluded by adopting a reactor-internal CRDM (Control Rod Drive Mechanism), many SMRs accept this concept. The first concept was provided by JAERI with the MRX reactor which uses an electric motor with a ball screw driveline. Babcock and Wilcox introduced the concept in an mPower reactor that adopts an electric motor with a roller screw driveline and hydraulic system, and Westinghouse Electric Co. proposes an internal Control Rod Drive in its SMR with an electric motor with a latch mechanism. In addition, several other applications have been reported thus far. The reactor-internal CRDM concept is now widely adopted in many SMR designs, and this concept may also be applied in an evolutionary reactor development. So the preliminary study is conducted based on the SMART CRDM design. A preliminary design concept for a reactor-internal CRDM was proposed and evaluated through an electromagnetic analysis. It was found that there is an optimum design for the motor housing, and the results may contribute to the realization a reactor-internal CRDM for an evolutionary reactor development. More detailed analysis results will be reported later

An emergentist vs a linear approach to social change processes: a gender look in contemporary India between modernity and Hindu tradition.

Using Census of India data from 1901 to 2011 and national and international reports on women's condition in India, beginning with sex ratio trends according to regional distribution up to female infanticides and sex-selective abortions and dowry deaths, this study examines the sociological aspects of the gender imbalance in modern contemporary India. Gender inequality persistence in India proves that new values and structures do not necessarily lead to the disappearance of older forms, but they can co-exist with mutual adaptations and reinforcements. Data analysis suggests that these unexpected combinations are not comprehensible in light of a linear concept of social change which is founded, in turn, on a concept of social systems as linear interaction systems that relate to environmental perturbations according to proportional cause and effect relationships. From this perspective, in fact, behavioral attitudes and interaction relationships should be less and less proportionally regulated by traditional values and practices as exposure to modernizing influences increases. And progressive decreases should be found in rates of social indicators of gender inequality like dowry deaths (the inverse should be found in sex ratio trends). However, data does not confirm these trends. This finding leads to emphasize a new theoretical and methodological approach toward social systems study, namely the conception of social systems as complex adaptive systems and the consequential emergentist, nonlinear conception of social change processes. Within the framework of emergentist theory of social change is it possible to understand the lasting strength of the patriarchal tradition and its problematic consequences in the modern contemporary India.

Full Text Available Applying the method of retrospective analysis the article deals with the process of forming the scientific fundamentals and the search by the international community of effective and adequate to the current stage of social development public administration system. The author attempts to analyze, in a number of cases in terms of models, features of public administration systems at different stages of historical development, drawing attention to reasons why the Soviet model of public administration did not manage to meet competition, did not provide the required social effect and as a natural result suffered a defeat in the global confrontation between the two social systems. Current models and theoretical concepts of public administration, especially the "new public administration", which became scientific basis for administrative reforms implemented in many countries, are the particular subject of scientific analysis. The author draws attention to major comprehensive characteristics of modern state public administration: making it impossible to absolutize principles of traditional hierarchy system of forced administration; globalization - gradual destruction of boundaries between national and international levels of administration, the growing role of supranational subjects of administration relations; informatization - increasing importance of information and communication technologies and of political networks: development of civil society, especially political parties and non-governmental organizations, growing public involvement in discussion and adoption of the most important administrative decisions; making the state policy more pluralistic and which will result in the formation of nonlinear - humanistic social consciousness as the intellectual basis of modern social governance. The author's position is that Russia is yet to solve the issue of choosing a public administration model that would be effective for further administrative

Mathematical modelling in engineering: A proposal to introduce linear algebra concepts

2016-03-01

Full Text Available The modern dynamic world requires that basic science courses for engineering, including linear algebra, emphasize the development of mathematical abilities primarily associated with modelling and interpreting, which aren´t limited only to calculus abilities. Considering this, an instructional design was elaborated based on mathematic modelling and emerging heuristic models for the construction of specific linear algebra concepts:  span and spanning set. This was applied to first year engineering students. Results suggest that this type of instructional design contributes to the construction of these mathematical concepts and can also favour first year engineering students understanding of key linear algebra concepts and potentiate the development of higher order skills.
