  2. On Human Essence

    Full Text Available To offer a response to the challenge posed by the existentialism of M. Heidegger, the present work uses the ontology proposed by X. Zubiri in Sobre la esencia. The work, then, deals with thinking «about essence», but above all, «about human essence», which creates the difficulty raised by existentialism. The difference between «constitutive» and «conditional» proposed by Zubiri is studied in order to highlight the human being’s (and of all living beings in general character of not being made once and for all. If we designate essence in the classical sense (unalterable essence as «constitutive», we propose to bring Zubiri’s intuition to its limit by acknowledging another «essential» level, which is the «constitutional». The constitutional is not essential in tradition’s strict sense, but neither is it accidental; it is essential in a new sense, allowing the incorporation of changes in essenceitself. Thus, one arrives at the so-called processive (or dynamic essences, which, for not being made once and for all, necessarily include their being made.

    Essence is a methodology supporting innovative software teams. It is designed with agile development in mind to allow for the problem situation to talk back to the team as they go along building solutions. Traditional software development teams – and for that matter probably also development teams...... using technologies other than software – might also enjoy adapting Essence to suit their situation. Essence is not yet another method for generating ideas. There are plenty of good methods already, and for that reason I choose to focus less on idea generation and more on the thereafter. Most teams....... Essence is based on the idea that challenges are open to interpretation and choice. We may often choose how we understand a challenge and choose among several strategies for answering it. Software development and indeed software innovation are far from linear. Essence is built on structures rather than...

    We consider a connection between the holographic dark energy density and the kinetic k-essence energy density in a flat FRW universe. With the choice c{>=}1, the holographic dark energy can be described by a kinetic k-essence scalar field in a certain way. In this Letter we show this kinetic k-essential description of the holographic dark energy with c{>=}1 and reconstruct the kinetic k-essence function F(X)

  5. Essence and constitution in Zubiri

    2015-03-01

    Full Text Available The aim of this article is to expound Zubiri’s concept of essence and to begin a critical discussion and evaluation of his proposal. Before explaining what essence is, it is necessary to observe that, for our author, not all things have an essence: only «reality-things» but not «meaning-things» form part of the «essentiable domain». This distinction between «reality-things» and «meaning-things» supposes a new conception of nature. (Nature is not the opposite of the artificial, as the Greek term physis is.«Reality-things» form a constitutional and «closed» system of non-causal and non-«external» characteristics or traits. These «foundational characteristics» of constitution, then, are precisely the essence. The article discusses critically the assumptions of this doctrine (reality, ontological pluralism, foundation and its possible limits in the light of contemporary science. It can be a useful theory for the philosophy of language.

  9. No-Go Theorem for k-Essence Dark Energy

    International Nuclear Information System (INIS)

    Bonvin, Camille; Caprini, Chiara; Durrer, Ruth

    2006-01-01

    We demonstrate that if k-essence can solve the coincidence problem and play the role of dark energy in the Universe, the fluctuations of the field have to propagate superluminally at some stage. We argue that this implies that successful k-essence models violate causality. It is not possible to define a time ordered succession of events in a Lorentz invariant way. Therefore, k-essence cannot arise as a low energy effective field theory of a causal, consistent high energy theory

  13. Kinetic k-essence ghost dark energy model

    International Nuclear Information System (INIS)

    Rozas-Fernández, Alberto

    2012-01-01

    A ghost dark energy model has been recently put forward to explain the current accelerated expansion of the Universe. In this model, the energy density of ghost dark energy, which comes from the Veneziano ghost of QCD, is proportional to the Hubble parameter, ρ D =αH. Here α is a constant of order Λ QCD 3 where Λ QCD ∼100 MeV is the QCD mass scale. We consider a connection between ghost dark energy with/without interaction between the components of the dark sector and the kinetic k-essence field. It is shown that the cosmological evolution of the ghost dark energy dominated Universe can be completely described a kinetic k-essence scalar field. We reconstruct the kinetic k-essence function F(X) in a flat Friedmann-Robertson-Walker Universe according to the evolution of ghost dark energy density.

    We investigate cosmological dynamics of models with higher-order corrections to the canonical (second-order) kinetic lagrangian for a scalar field, which have been termed k -essence . We study the qualitative dynamics of simple purely kinetic k-essence models and find that the simplest attempts to construct non-singular cosmological models by including higher-order terms in the kinetic lagrangian fail because of a different type of singularity where the scalar field theory becomes ill-defined

    2013-09-01

    Full Text Available As opposed to more mature subjects, software engineering lacks general theories that establish its foundations as a discipline. The Essence Theory of software engineering (Essence has been proposed by the Software Engineering Methods and Theory (SEMAT initiative. The goal of Essence is to develop a theoretically sound basis for software engineering practice and its wide adoption. However, Essence is far from reaching academic- and industry-wide adoption. The reasons for this include a struggle to foresee its utilization potential and a lack of tools for implementation. SEMAT Accelerator (SematAcc is a Web-positioning tool for a software engineering endeavor, which implements the SEMAT’s Essence kernel. SematAcc permits the use of Essence, thus helping to understand it. The tool enables the teaching, adoption, and research of Essence in controlled experiments and case studies.

    To understand clinical practice benchmarking from the perspective of nurses working in a large acute NHS trust and to determine whether the nurses perceived that their commitment to Essence of Care led to improvements in care, the factors that influenced their role in the process and the organisational factors that influenced benchmarking. An ethnographic case study approach was adopted. Six themes emerged from the data. Two organisational issues emerged: leadership and the values and/or culture of the organisation. The findings suggested that the leadership ability of the Essence of Care link nurses and the value placed on this work by the organisation were key to the success of benchmarking. A model for successful implementation of the Essence of Care is proposed based on the findings of this study, which lends itself to testing by other organisations.

    Post cesarean (CS) pain is a challenging problem for the obstetricians, because it may interfere with mother and baby's well-being. Many approaches have been ever proposed to diminish this pain, each one with particular benefits and limitations. Aromatherapy is a complementary therapy especially for controlling pain. This study aimed at evaluating the effect of lavender essence on post CS pain. In a single-blind clinical trial, 200 term pregnant women with planned elective CS were recruited in a 12 month period of time. They were randomized in two 100-patient groups; received either lavender essence (the case group) or a similar clinically neutral aromatic material (the control group) thorough oxygen mask for 3 min 3 h after receiving similar intravenous analgesics. The Visual Analogue Scale (VAS) was employed to determine the level of post CS pain. The VAS was documented half hour after first intervention. Eight and 16 h later, the aromatherapy was repeated and half hour after each intervention, corresponding VAS was documented. The two groups were matched for demographics and obstetrical history. The baseline VAS was comparable between the two groups. The mean VAS decreased significantly by 16 h after the first intervention in both groups (p aromatherapy by using lavender essence is a successful and safe complementary therapy in reducing pain after CS.

    We define a generalization of scalar fields with non-canonical kinetic term which we call exotic k-essence or, briefly, exotik. These fields are generated by the global description of cosmological models with two interactive fluids in the dark sector and under certain conditions they correspond to usual k-essences. The formalism is applied to the cases of constant potential and of inverse square potential and also we develop the purely exotik version for the modified holographic Ricci type (MHR) of dark energy, where the equations of state are not constant. With the kinetic function F = 1 + mx and the inverse square potential we recover, through the interaction term, the identification between k-essences and quintessences of an exponential potential, already known for Friedmann-Robertson-Walker and Bianchi type I geometries. Worked examples are shown that include the self-interacting MHR and also models with crossing of the phantom divide line (PDL). (orig.)

    The essence of subclassing is the ability to represent classification hierarchies reflecting domain concepts. With the right class mechanism there is no need for a separate type/subtype mechanism, and general classes may have behavior specifications so that subclassing also implies code reuse....... Sometimes the application is so well defined (known) that developers may readily start out with classes that represent domain concepts. Singular objects have been around for some time, so a new kind of language with equal support for both objects and classes would simply ask for tool support for objects...

    In thiswork,we present a study of a purely kinetic k-essence model, characterized basically by a parameter α in presence of a bulk dissipative term, whose relationship between viscous pressure Π and energy density ρ of the background follows a polytropic type law, Π ∝ ρ{sup λ+1/2}, where λ, in principle, is a parameter without restrictions. Analytical solutions for the energy density of the k-essence field are found in two specific cases: λ = 1/2 and λ = (1 - α)/2α, and then we show that these solutions possess the same functional form as the non-viscous counterpart. Finally, both approaches are contrasted with observational data from type Ia supernova, and the most recent Hubble parameter measurements, and therefore, the best values for the parameters of the theory are found.

  7. Normative Judgments and Individual Essence.

    Science.gov (United States)

    De Freitas, Julian; Tobia, Kevin P; Newman, George E; Knobe, Joshua

    2017-04-01

    A growing body of research has examined how people judge the persistence of identity over time-that is, how they decide that a particular individual is the same entity from one time to the next. While a great deal of progress has been made in understanding the types of features that people typically consider when making such judgments, to date, existing work has not explored how these judgments may be shaped by normative considerations. The present studies demonstrate that normative beliefs do appear to play an important role in people's beliefs about persistence. Specifically, people are more likely to judge that the identity of a given entity (e.g., a hypothetical nation) remains the same when its features improve (e.g., the nation becomes more egalitarian) than when its features deteriorate (e.g., the nation becomes more discriminatory). Study 1 provides a basic demonstration of this effect. Study 2 shows that this effect is moderated by individual differences in normative beliefs. Study 3 examines the underlying mechanism, which is the belief that, in general, various entities are essentially good. Study 4 directly manipulates beliefs about essence to show that the positivity bias regarding essences is causally responsible for the effect. Copyright © 2016 Cognitive Science Society, Inc.

    Full Text Available A new approach to interpreting the landscape is examined by accepting its complexity through inductive reasoning. While attempting to identify the essence of the landscape in the city and municipality of Óbidos, Portugal, several architectural recommendations of Venturi (2004 have been adapted as a framework for understanding this landscape. These will then guide the process of landscape transformation through:•••using the concepts of closed and contained spaces and the concept of fluid space;•recognising the existence of interstitial open spaces;•using those elements which are common to the distinct typologies of space;•defining the components that should be respected and those that can be respected;•observing landscape as a whole , while emphasising the relationship between the parts and the whole; and•rejecting simplification in the landscape transformation process.valuing the ambiguity incorporating the complexity Underlying this approach is the belief that the process of transformation must be based on the essence of each landscape. This implies the use of elements and structures of the landscape which are related to ecological, morphological and cultural systems. These elements and structures represent points of reference which should be considered in the process of landscape transformation.

    Rao, B.; Celier, J.

    1997-12-31

    This paper presents the results and recommendations derived from a detailed assessment of a butane supply and butane transportation system. Based on a hazard and operability (HAZOP) study performed earlier, the need to undertake a more detailed assessment of the risks associated with the handling and transport of butane for the maleic anhydride (MAN) unit at a site was identified in order to ensure that all reasonable risk mitigation actions had been evaluated. Therefore, PLG initiated this study to quantify the likelihood and consequences of butane releases. The scope of the risk assessment includes all operations and activities with the handling and transport of butane, including: loading of butane trucks at the butane loading terminal; transport of butane by tank truck from the loading terminal to the plant site; unloading of the butane into the MAN unit storage sphere. Risks were quantified in terms of the likelihood of butane releases that could leas to a fire (pool or vapor cloud), an unconfined vapor cloud explosion (UVCE), or a boiling expanding vapor explosion (BLEVE), and the consequences of such releases in terms of the potential impact on both plant workers and the general public who live or work near the butane loading terminal, the transport route, or the plant site.

    In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, we can consider the Universe to be filled with dust-like matter in the form of discretely distributed galaxies, a K -essence scalar field, playing the role of dark energy, and radiation as matter sources. We investigate such a Universe in the mechanical approach. This means that the peculiar velocities of the inhomogeneities (in the form of galaxies) as well as the fluctuations of the other perfect fluids are non-relativistic. Such fluids are designated as coupled because they are concentrated around the inhomogeneities. In the present paper, we investigate the conditions under which the K -essence scalar field with the most general form for its action can become coupled. We investigate at the background level three particular examples of the K -essence models: (i) the pure kinetic K -essence field, (ii) a K -essence with a constant speed of sound and (iii) the K -essence model with the Lagrangian bX + cX {sup 2}− V (φ). We demonstrate that if the K -essence is coupled, all these K -essence models take the form of multicomponent perfect fluids where one of the component is the cosmological constant. Therefore, they can provide the late-time cosmic acceleration and be simultaneously compatible with the mechanical approach.

  2. Dynamics of k-essence

    International Nuclear Information System (INIS)

    Rendall, Alan D

    2006-01-01

    There are a number of mathematical theorems in the literature on the dynamics of cosmological models with accelerated expansion driven by a positive cosmological constant Λ or a nonlinear scalar field with potential V (quintessence) which do not assume homogeneity and isotropy from the beginning. The aim of this paper is to generalize these results to the case of k-essence models which are defined by a Lagrangian having a nonlinear dependence on the kinetic energy. In particular, Lagrangians are included where late-time acceleration is driven by the kinetic energy, an effect which is qualitatively different from anything seen in quintessence models. A general criterion for isotropization is derived and used to strengthen known results in the case of quintessence

  3. Formal values and the essence of art

    Full Text Available Review of: Paul van den Akker, Looking for Lines. Theories on the Essence of Art and the Problem of Mannerism, Amsterdam: Amsterdam University Press 2010. The problem of the categorical definition of the nature of art was often regarded as the central challenge of art history. Paul van den Akker examines the history of this problem from the eighteenth century to the 1960s. Thus his book addresses ‘the essence of art history’. In order to do so, he uses the extremely contradictory discussions of ‘Mannerism’ and the use of the line in mannerist art as a relevant case study, and this is supplemented with extensive excursuses on historic concepts of ‘classical art’, of Renaissance painting, of medieval art, or connoisseurship. Johann Joachim Winckelmann, Heinrich Wölfflin, Alois Riegl and John Shearman play key roles in van den Akker’s book. The review mainly asks for the specificity of the analytical categories and the changing role of the visual material used by the antiquarians and early art historians from the later seventeenth to the early twentieth centuries to illustrate and accompany their texts and arguments.

    The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

    We investigated accuracy in recalling past emotional behaviours and emotionality. Male couples discussed the history of their relationship, and coders rated the extent to which each partner engaged in behaviours such as complimenting or criticising. These ratings were combined into dimensions representing the deeper, emotional essence of that partner's discussion (expressions of We-ness, Fondness, Negativity, and Disappointment). Four years later, participants accurately recalled some of their own and some of their partner's emotional gist-level behaviours, but their answers indicated that they also remembered the emotional essence of the conversation. We conclude that individuals can retain the emotional essence of an experience for a long time, and that they may use this memory to infer, in part, gist-level details of the experience.

    We report the discovery and orbital determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging data set. Two additional objects discovered in a similar search of the SDSS-II Supernova Survey database were recovered in this effort. ESSENCE repeatedly observed fields far from the solar system ecliptic (-21{sup o} < {beta} < -5{sup o}), reaching limiting magnitudes per observation of I {approx} 23.1 and R {approx} 23.7. We examine several of the newly detected objects in detail, including 2003 UC{sub 414}, which orbits entirely between Uranus and Neptune and lies very close to a dynamical region that would make it stable for the lifetime of the solar system. 2003 SS{sub 422} and 2007 TA{sub 418} have high eccentricities and large perihelia, making them candidate members of an outer class of TNOs. We also report a new member of the 'extended' or 'detached' scattered disk, 2004 VN{sub 112}, and verify the stability of its orbit using numerical simulations. This object would have been visible to ESSENCE for only {approx}2% of its orbit, suggesting a vast number of similar objects across the sky. We emphasize that off-ecliptic surveys are optimal for uncovering the diversity of such objects, which in turn will constrain the history of gravitational influences that shaped our early solar system.

  9. Essence and resolution of international climate negotiation

    Directory of Open Access Journals (Sweden)

    Xiang-Wan Du

    2014-09-01

    Full Text Available In essence, international climate negotiation is a serious and responsible global effort, despite various conflicts, to establish a rational international climate regime. In essence, tackling climate changes is leading the globe to actualize sustainable development of all humankind along the low-carbon, green, and cyclic-development path. Thus, climate negotiation should be driving all parties to achieve a global climate regime arrangement in a constructive way. Therefore, this paper suggests focusing on the following three major recommendations: early developed countries take the lead in committing positively to absolute emission reduction; the developing countries contribute according to their abilities and stages of development; the developed countries perform real deeds using their funds and technology. Based on substantial breakthrough that would be made, progressive supplement and improvement could be accomplished through the mechanism of review and adjustment under the Convention framework. This path represents a combination of bottom-up and top-down. The ultimate way out of international climate negotiation lies in win-win cooperation. Profound reasons for China to participate proactively and practically in international climate negotiation, based on its actual conditions, are the internal wants and needs of its scientific and sustainable development, as well as the undertaking of international responsibilities as a responsible, large, developing country.

    Science.gov (United States)

    Cisterna, Adolfo; Hassaine, Mokhtar; Oliva, Julio; Rinaldi, Massimiliano

    2017-12-01

    We construct new black brane solutions in the context of Horndeski gravity, in particular, in its K-essence sector. These models are supported by axion scalar fields that depend only on the horizon coordinates. The dynamics of these fields is determined by a K-essence term that includes the standard kinetic term X and a correction of the form Xk. We find both neutral and charged exact and analytic solutions in D -dimensions, which are asymptotically anti-de Sitter. Then, we describe in detail the thermodynamical properties of the four-dimensional solutions and we compute the dual holographic DC conductivity.

    The k-essence theory with a power-law function of (∂φ){sup 2} and Rastall's non-conservative theory of gravity with a scalar field are shown to have the same solutions for the metric under the assumption that both the metric and the scalar fields depend on a single coordinate. This equivalence (called k-R duality) holds for static configurations with various symmetries (spherical, plane, cylindrical, etc.) and all homogeneous cosmologies. In the presence of matter, Rastall's theory requires additional assumptions on how the stress-energy tensor non-conservation is distributed between different contributions. Two versions of such non-conservation are considered in the case of isotropic spatially flat cosmological models with a perfect fluid: one (R1) in which there is no coupling between the scalar field and the fluid, and another (R2) in which the fluid separately obeys the usual conservation law. In version R1 it is shown that k-R duality holds not only for the cosmological models themselves but also for their adiabatic perturbations. In version R2, among other results, a particular model is singled out that reproduces the same cosmological expansion history as the standard ΛCDM model but predicts different behaviors of small fluctuations in the k-essence and Rastall frameworks.

    2014-08-01

    Full Text Available This article examines the essential oils that are the central tools of aromatherapy and uses them as a case study for different approaches to material culture. It considers the conceptual and political implications of thinking of essential oils as, in turn, commodities, materials and essences. I argue that both cultural studies and aromatherapy have something to learn from each other. Classic materialist approaches might do well to focus more attention on the material properties and effects of things. Aromatherapy, on the other hand, could benefit from the enriched political understanding associated with classic materialist critique. New materialist strains of cultural studies may also find the vibrancy of matter that underpins many CAM/New Age practices worthy of examination.

Cette succession de choix s’insère dans un faisceau de contraintes environnementales, techniques et financières. Ceci rend le processus décisionnel complexe, du fait notamment de la multiplicité des acteurs potentiellement impliqués. Dans ce contexte, la contribution de chercheurs peut consister à fournir des méthodes, permettant d’apporter un éclairage sur les conséquences potentielles en terme de développement durable, des décisions successives prises depuis la conception d’un projet routier jusqu’à sa réalisation. Dans cette perspective, une analyse des critères décisionnels propres à chacun des acteurs au sein du processus décisionnel, est nécessaire.

    We analyze a Dvali-Gabadadze-Porrati (DGP) brane filled with a k-essence field and assume the k field evolving linearly with the cosmic time of the brane. We then solve analytically the Friedmann equation and deduce the different behavior of the brane at the low- and the high-energy regimes. The asymptotic behavior can be quite different involving accelerating branes, big bangs, big crunches, big rips, or quiescent singularities. The latter correspond to a type of sudden singularity.

    New fifth forces have not yet been detected in the laboratory or in the solar system, hence it is typically difficult to introduce new light scalar fields that would mediate such forces. In recent years it has been shown that a number of non-linear scalar field theories allow for a dynamical mechanism, such as the Vainshtein and chameleon ones, that suppresses the strength of the scalar fifth force in experimental environments. This is known as screening, however it is unclear how common screening is within non-linear scalar field theories. k-essence models are commonly studied examples of non-linear models, with DBI as the best motivated example, and so we ask whether these non-linearities are able to screen a scalar fifth force. We find that a Vainshtein-like screening mechanism exists for such models although with limited applicability. For instance, we cannot find a screening mechanism for DBI models. On the other hand, we construct a large class of k-essence models which lead to the acceleration of the Universe in the recent past for which the fifth force mediated by the scalar can be screened.

The essence of hypnosis is not to be found in hetero-hypnosis; instead, it lies in the spontaneous self-activation of that mode of neural functioning. The hypnosis field has substantially lost sight of spontaneous self-activation, because the word hypnosis is usually used to mean hetero-hypnosis. Self-activation of this mode of neural functioning is the necessary sine qua non of hypnotic psychopathology. Moreover, self-activation of trance is the characteristic hypnotic behavior of a distinct subset of highly hypnotizable individuals.

  9. Definition and Essence of Information

    Full Text Available It has been 60 years since the essential attributes of information were explored in the field of philosophy, resulting in many contentious schools of thought and a wide division of opinions. Some scholars in China and abroad have been trying to build a new system of information philosophy from an ontological perspective, so as to explain the world. In this paper, the author puts forward a definition of information and its mathematical expressions in order to demonstrate that information is the collection of three kinds of attributes of things. Analysis suggests that the essence of information is the interaction of matters and the representation of the law of causality in philosophy. The paper also explores the ways in which information—as a noun—is a term that people have customarily used and confused. Eventually, the induction, differentiation and utilization of information, as conventionally understood, should be applied into studying matters themselves.

    Clinical nursing process recording (CNPR) has been shown to be an effective tool for facilitating student-centered teaching and learning in nursing education. Yet, the essence and process of this tool have yet to be sufficiently explored and clarified. To explore the essence of CNPR in the contexts of clinical teaching and learning. Reflective analysis was used as the phenomenological approach to analyze the qualitative data, which were transcribed from the oral responses of the six participants who were attending the Clinical Nursing Education Forum. A total of five sessions of the Clinical Nursing Education Forums were conducted. The content of the Clinical Nursing Education Forums consisted of a series of 12 narrative writings of CNPR that were written by a senior student and read and commented on by the student's clinical instructor. Three groups of the essence and process of clinical teaching and learning were inductively identified as: (a) mobilizing autonomous, self-directed learning behavior from self-writing and re-storying; (b) establishing the student-instructor dialogical relationship from mutual localization; and (c) co-creating a learning environment in education and in clinical practice. When used as an interactive teaching and learning tool, CNPR promotes mutual understanding by re-locating the self in the coexisting roles of student nurse, instructor, and patient in a series of nursing care situations. This re-location facilitates students' self-directed learning, enhances the abilities of asking question, waiting for and accompany with the instructor; and promotes the self-care capabilities of patients.

  12. Defining an essence of structure determining residue contacts in proteins.

    The network of native non-covalent residue contacts determines the three-dimensional structure of a protein. However, not all contacts are of equal structural significance, and little knowledge exists about a minimal, yet sufficient, subset required to define the global features of a protein. Characterisation of this "structural essence" has remained elusive so far: no algorithmic strategy has been devised to-date that could outperform a random selection in terms of 3D reconstruction accuracy (measured as the Ca RMSD). It is not only of theoretical interest (i.e., for design of advanced statistical potentials) to identify the number and nature of essential native contacts-such a subset of spatial constraints is very useful in a number of novel experimental methods (like EPR) which rely heavily on constraint-based protein modelling. To derive accurate three-dimensional models from distance constraints, we implemented a reconstruction pipeline using distance geometry. We selected a test-set of 12 protein structures from the four major SCOP fold classes and performed our reconstruction analysis. As a reference set, series of random subsets (ranging from 10% to 90% of native contacts) are generated for each protein, and the reconstruction accuracy is computed for each subset. We have developed a rational strategy, termed "cone-peeling" that combines sequence features and network descriptors to select minimal subsets that outperform the reference sets. We present, for the first time, a rational strategy to derive a structural essence of residue contacts and provide an estimate of the size of this minimal subset. Our algorithm computes sparse subsets capable of determining the tertiary structure at approximately 4.8 A Ca RMSD with as little as 8% of the native contacts (Ca-Ca and Cb-Cb). At the same time, a randomly chosen subset of native contacts needs about twice as many contacts to reach the same level of accuracy. This "structural essence" opens new avenues in the

Methodology. The understanding of human nature problems, human existence in the form of sports activity, the potential of anthropological picture of the sporting world. In this case sport is considered as a culture which gives a chance to define it as an activity which involves positive results aimed at the realization of human essence as well as destructive ones that are aimed at the destruction of a sportsman personality. Scientific novelty is in the research of insufficiently studied theme of sportsman-dimension from the anthropological point of view. Practical value of the work is in elaborating the theme in context of scientific research performance at the department of theory and physical training methods and sports and the disciplines of Melitopol state pedagogical university named after Bogdan Khmelnitskiy. Philosophy of sport is a new subject and a new scientific direction, in the context of which the problems of sport, development of sporting values and outlook of the youth, their socialization in the sports activity are explored. Conclusions the introduction of the anthropological basis of sportsman-dimension essence in sport promotes the possibility to show entire human nature, its creativity in sporting life, therefore it leads an individual to a self-formation. The anthropological basis of the sportsman-dimension is aimed at the realization of a person's generic essence for increasing the human potential, physical health of young generation due to physical training and sports.

    2016-09-26

    Although biology has achieved great successes in recent years, we have not got a clear idea on "what is life?" Actually, as explained here, the main reason for this situation is that there are two completely distinct aspects for "life", which are usually talked about together. Indeed, in respect to these two aspects: Darwinian evolution and self-sustaining, we must split the concept of life correspondingly, for example, by defining "life form" and "living entity", separately. For life's implementation (related to the two aspects) in nature, three mechanisms are crucial: the replication of DNA/RNA-like polymers by residue-pairing, the sequence-dependent folding of RNA/protein-like polymers engendering special functions, and the assembly of phospholipid-like amphiphiles forming vesicles. The notion "information" is significant for us to comprehend life phenomenon: the life form of a living entity can just be defined by its genetic information; Darwinian evolution is essentially an evolution of such information, transferred across generations. The in-depth analysis concerning the essence of life would improve our cognition in the whole field of biology, and may have a direct influence on its subfields like the origin of life, artificial life and astrobiology.

    Full Text Available Several authors and consulting firms show statistics indicating that at least 50% of all CRM projects fail. Some of them attempt to point out a list of factors in order to guarantee successful CRM implementation and application. However, few people (either academics or practitioners attempt to discuss or consider the essence of the idea of CRM. The main goal of this exploratory research is to discuss the CRM essence through a phenomenological approach. This paper assumes that one of the main reasons for CRM failure is the lack of understanding about the true meaning and implication of practices for managing the relationship with customers. Therefore, we need to question the essence of CRM itself and discuss the very concept of relationship. We claim that the idea of CRM involves very serious issues about institutions, roles, power and ethical values that have to be considered. In this article, we attempt to analyze the essence of relationship, trying to go beyond the common meaning of CRM. As the main results of this paper, we offer a critical reflection related to the different faces and aspects of the CRM phenomenon, not only as a matter of IT applications, but also as a strategy and even as an organizational philosophy.

    Full Text Available The article conducts the study of essence of the change notion at stages of the life cycle of an enterprise. It justifies a necessity of study of cyclic development of enterprises within the concept of managing changes. It shows interconnection of such notions as functioning, development, flexibility and adaptability of an enterprise. It generalises and shows the essence of scientific studies of cyclic development of an enterprise. In the result of the study it reveals that evolution of concepts of managing changes and life cycle have a complex and ambiguous history. Each stage is connected with certain political, social and economic factors, which should be considered not only in the context of the international market, but, first of all, within experience of the national economy. This has to do with relatively small independent experience of the Ukrainian economy, which makes it difficult to make decisions on the basis of the organisational memory of an enterprise. The said factors make for a deeper study of theoretical and practical approaches to the study of changes at the stages of enterprise development.

The experimental group received 2 drops of Lavender essence inhaled at three stages (4-5, 6-7, 8-9 cm cervical dilation) and severity of the labor pain and duration of labor was measured before and after intervention. The control group was treated with distilled water as a placebo in the similar ways, too. The results showed that difference in the labor pain before and after intervention in two groups was significant (P = 0/001). But there was no difference in mean duration of the active phase and the second stage of labor between the two groups. Lavender essence aromatherapy may be an effective therapeutic option for pain management for women in labor. Published by Elsevier Ltd.

  18. Personnel Motivation: Essence and Modern Problems

    2014-02-01

    Full Text Available The goal of the article lies in the study of the essence of labour motivation and establishment of differences between stimulation and motivation. While analysing the “motivation” notion the article shows that internal wishes and goals of a human being stimulate this human being to act in a specific direction in order to achieve the set goal. Moreover, the article states that there are two theories of motivation in the modern economic literature – meaningful and procedural. As analysis of indicators of payment for labour in Ukraine shows, there is a rather significant differentiation of sizes of wages by branches of economic activity and there are arrears of wages. These indicators to a certain extent facilitate reduction of motivation of workers for labour activity. In order to increase employment of the population under conditions of the market economy, it is necessary to develop a system of measures for elimination of these problems at the state level and also to reduce to the minimum manifestations of “shadowing” wages.

    Full Text Available The article considers a fashion as a real and an acting social fact that affects many aspects of the life of the individual and society. The interest in the ability to reflect the specific modes of social transformations becomes the basis for constructing a theoretical system of knowledge about it. Fashion as a scientific fact characterizes social processes that find manifestation in the outward culture forms and fashion meanings indicating the fashion values, which are endowed with certain properties of objects and events. Fashion, by definition, has a tendency to constant movement and innovation. So it always reflects the social and cultural content of a certain period, the essence of which is disclosed in its sociocultural context. Fashion phenomenon is associated with diverse social relationships, in this connection it is manifested in a multidisciplinary description of various scientific facts. The theory of fashion generation consists of separate concepts that complement each other or makes alternative viewpoints. The development of science requires a search for a new approach.

    2014-01-01

    We use one of the simplest forms of the K-essence theory and we apply it to the classical anisotropic Bianchi type I cosmological model, with a barotropic perfect fluid (p=γρ) modeling the usual matter content and with cosmological constant Λ. Classical exact solutions for any γ≠1 and Λ=0 are found in closed form, whereas solutions for Λ≠0 are found for particular values in the barotropic parameter. We present the possible isotropization of the cosmological model Bianchi I using the ratio between the anisotropic parameters and the volume of the universe. We also include a qualitative analysis of the analog of the Friedmann equation.

    2002-01-01

    Full Text Available Depuis longtemps, la Commission, le Parlement et le Conseil encouragent le développement des sources d’énergie renouvelables, et plus particulièrement des biocarburants. Cela s’est traduit, entre autres, par la publication en novembre 2000 d’un livre vert intitulé « Vers une stratégie européenne de sécurité d’approvisionnement énergétique », qui fixe comme objectif, d’ici 2020, le remplacement de 20% des carburants classiques par des carburants de substitution pour le transport routier. Plus récemment, en juin 2001, au sommet de Göteborg, a été souligné le rôle important des biocarburants dans la lutte contre le changement climatique et le développement des énergies propres. Ces encouragements restaient au niveau de la déclaration d’intention faute de moyens administratifs et fiscaux pour bâtir une véritable stratégie. Depuis le 7 novembre 2001, les choses semblent évoluer : en effet, à cette date, le collège des Commissaires a adopté une communication sur les carburants de substitution pour les transports routiers et une série de mesures visant à promouvoir l’utilisation des biocarburants. De plus - et c’est ce qui est fondamental - cette communication était assortie de deux propositions de directives, l’une visant à promouvoir l’utilisation des biocarburants dans les transports, l’autre concernant la possibilité d’appliquer un taux d’accises réduit sur certaines huiles minérales qui contiennent des biocarburants et sur les biocarburants.

    2012-06-01

    Full Text Available This 1994 article by Jeffrey Gray originally appeared in the journal NOVEL: A Forum on Fiction (Duke University Press. An early foray into transnational American Studies, Gray’s analysis of the role “Europe” plays both in the narrative and in the life of the author herself begins with a discussion of the object of art—the self as exoticized, distanced other—imagined and displayed against the carceral black body in the American imaginary, an imaginary that holds the protagonist, Helga, hostage to an indeterminacy represented by her mulatto status. Gray argues that the “quicksand” of the search for essence, whether located in the body or in the eyes of others, eventually dissolves the protagonist’s sense that a change of place can change the truth that essence does not exist. Gray references the shared observation among African American international celebs (Richard Wright, James Baldwin, and Josephine Baker—whose 1973 interview with Henry Louis Gates, Jr., is cited that “being different is different” in Europe, yet that otherness is finally also not an experience of self, which the narrative (and perhaps the author’s life as well proves to be endlessly deferred.

    Full Text Available The article is aimed at researching the historical evolution and a current interpretation of the definition of essence of the category of «competitiveness of enterprise of the automobile industry». Using the monographic analysis, the article reviews the historical evolution of the definition of essence of the category of «competitiveness of enterprise» in the national scientific literature in the period from 2007 to 2016. It has been concluded that the essence of the concept of «competitiveness of enterprise» is actually reduced to the competitiveness of products or operational efficiency. The author’s own definition of the essence of the category of «competitiveness of enterprise of the automobile industry» has been suggested: it has been specified that under the given term be understood «...the dynamic ability of enterprise of the automobile industry to ensure the efficiency of all activities as result of interaction of the internal competitive potential and the external competitive environment factors in accordance with the chosen competitive strategy at a certain stage of the life cycle».

    Parity effect, which means that even-odd property of an integer physical parameter results in an essential difference, ubiquitously appears and enables us to grasp its physical essence as the microscopic mechanism is less significant in coarse graining. Here we report a new parity effect of quantum Hall edge transport in graphene antidot devices with pn junctions (PNJs). We found and experimentally verified that the bipolar quantum Hall edge transport is drastically affected by the parity of the number of PNJs. This parity effect is universal in bipolar quantum Hall edge transport of not only graphene but also massless Dirac electron systems. These results offer a promising way to design electron interferometers in graphene.

    Full Text Available The purpose of the article is to disclose the economic essence of the category of «costs» as an object of accounting and internal control. A number of approaches to defining the economic essence of the concepts of «costs», «control» and «internal control» have been allocated. In the course of the study it was found that the most common approaches to interpretation of the concept of «costs» is the disclosure of its essence from the standpoints of economic theory and accounting; concepts of «control» and «internal control» – from the standpoints of functional, systemic and process approaches. The authors’ own definition of the synthesis concept of «internal control of costs» has been proposed, which suggests understanding it as the system of control measures, observations and procedures aimed at identifying deviations in the accounting of costs of enterprise, establishing legitimacy, validity, rationality, efficiency and economic feasibility of their implementation with a view to preventing and exclusion such deviations and unjustified losses in the future. Prospect for further researches in this direction is search of efficient forms, methods and instruments for management of costs of enterprise.

    Full Text Available In the Lithuanian acts of law and in the scientific literature there are no clear criteria and notions to define a square. The unbuilt city space places or the gaps between buildings are often defined as the squares, which do not have clear limits or destination. The mandatory attributes of the place which is called the square are indicated in the article, the notion of square is defined. The article deals with Lithuanian squares theme, analyses the differences between representation and representativeness. The article aims to indicate an influence of city environmental context and monument in the square on its function. The square is an independent element of city plan structure, but it is not an independent element of city spatial structure. The space and environment of the square are related to each other not only by physical, aesthetical relations, but as well as by causalities, which may be named as the essences of squares’ formation. The interdisciplinary discourse analysis method is applied in the article.

It has been found that the key business-indicators of the diagnosis system of transport activity as a component of the enterprise logistical system are: the coefficient of timeliness of freight transportation (delivery; coefficient of completeness of transportation; coefficient of freight safety conditions; coefficient of efficiency of freight transportation; coefficient of complexity of servicing freight owners; coefficient of satisfaction of freight owners’ demand, coefficient of readiness to operation of transport facilities per working day; coefficient of using vehicle kilometers travelled; coefficient of extensity of transport facility packing.

  12. Mind Perception Is the Essence of Morality.

    Science.gov (United States)

    Gray, Kurt; Young, Liane; Waytz, Adam

    2012-04-01

    Mind perception entails ascribing mental capacities to other entities, whereas moral judgment entails labeling entities as good or bad or actions as right or wrong. We suggest that mind perception is the essence of moral judgment. In particular, we suggest that moral judgment is rooted in a cognitive template of two perceived minds-a moral dyad of an intentional agent and a suffering moral patient. Diverse lines of research support dyadic morality. First, perceptions of mind are linked to moral judgments: dimensions of mind perception (agency and experience) map onto moral types (agents and patients), and deficits of mind perception correspond to difficulties with moral judgment. Second, not only are moral judgments sensitive to perceived agency and experience, but all moral transgressions are fundamentally understood as agency plus experienced suffering-that is, interpersonal harm-even ostensibly harmless acts such as purity violations. Third, dyadic morality uniquely accounts for the phenomena of dyadic completion (seeing agents in response to patients, and vice versa), and moral typecasting (characterizing others as either moral agents or moral patients). Discussion also explores how mind perception can unify morality across explanatory levels, how a dyadic template of morality may be developmentally acquired, and future directions.

    A qualitative metasynthesis was conducted to identify the essence of healing from sexual violence, as described by adults who experienced it as children or as adults. Based on the findings of 51 reports, four domains of healing were identified: (a) managing memories, (b) relating to important others, (c) seeking safety, and (c) reevaluating self. The ways of healing within each domain reflected opposing responses. The dialectical process identified for each of the four domains include, respectively: (a) calling forth memories, (b) regulating relationships with others, (c) constructing an “as-safe-as-possible” lifeworld, and (d) restoring a sense of self. These complex processes resulted in a new reality for the participants that was based on a greater sense of agency and provided a more satisfying life course. PMID:19415681

    Full Text Available The purpose of the paper is scientific grounding of theoretical and methodological approaches to the fundamental principles of the functioning of the existing system of financial support of the agrarian sector in Ukraine and its potential areas of its improvement through the construction of new effective financing mechanisms. Methodology. In the study the following methods are used: a comparative and morphological methods – to reveal the content and development of scientific thoughts about the interpretation of the concept of «financial support»; methods of systematization and generalization – to determine the functionality of the agricultural sector and the need of its financial support and to reveal the features of its functioning; systemic method – to construct a model of the implementation of agricultural sector financial support; logical method – for a consistent generalization of theoretical and practical scientific research statements. Results. Investigation of formation and development of the doctrine of financial support and systematization of scientific thoughts about its essence gives the opportunity to consider the content of the studied category in terms of the functional approach. Interpretation of the term “financial support” comes down to the statement that the formation of the theoretical foundations of the essence and the economic nature of financial support is a result of the achievements of several generations of scientists, each of whom invested a significant contribution to the development of the theory of the studied concept. This allowed us to analyze the term «financial providing» and to summarize the existing approaches in the light of the activities of the agricultural sector. In terms of functionality we found that financial support as a phenomenon can be seen in the context of its unique significance in the development of the economy. Practical implications. It was determined that the problems of

    Full Text Available The article is aimed at defining essence of the current cluster policy and its characteristics. It was specified that, in the process of developing and implementing regional, innovation and entrepreneurial policies, many governments drew attention to the clustering of economy as a means of achieving a high level of regional and national competitiveness. The current cluster policy needs to be integrated, that is, to unify different policies, programs, and means. One of the characteristics of the current cluster policy is its orientation towards public-private partnership. The efficient form of such a partnership is cluster organizations. The author’s vision of the current cluster policy is that both the State and the private sector should be parties to it. Emphasis has been placed on the need to support in Ukraine, at the State level, the innovation clusters that facilitate modernization of the existing economic sectors by combining the traditions and the challenges of modernity. It has been concluded that social organizations could be involved in the process of development and implementation of cluster policy in Ukraine. A prospect for further research can be development of the «intellectual specialization» strategy for regions as an important constituent of the current cluster policy.

    The practical realization of all types of mechanical motions converters is preceded by solving the task of their kinematic synthesis. In this way, the determination of the optimal values of the constant geometrical parameters of the chosen structure of the created mechanical system is achieved. The searched result is a guarantee of the preliminary defined kinematic characteristics of the synthesized transmission and in the first place, to guarantee the law of motions transformation. The kinematic synthesis of mechanical transmissions is based on adequate mathematical modelling of the process of motions transformation and on the object, realizing this transformation. Basic primitives of the mathematical models for synthesis upon a pitch contact point are geometric and kinematic pitch configurations. Their dimensions and mutual position in space are the input parameters for the processes of design and elaboration of the synthesized mechanical device. The study presented here is a brief review of the theory of pitch configurations. It is an independent scientific branch of the spatial gearing theory (theory of hyperboloid gears). On this basis, the essence and content of the corresponding primitives, applicable to the synthesis of spatial rack drives, are defined.

    Studying the essence of a syndrome has been a key challenge in the field of Chinese medicine. Until now, due to limitations of the methods available, the progress towards understanding such complicated systems has been slow. Metabonomics encompasses the dynamics, composition and analysis of metabolites, enabling the observation of changes in the metabolic network of the human body associated with disease. Being from the point of view of the whole organism, metabonomics provides an opportunity to study the essence of a syndrome to an unprecedented level. Phlegm and blood stasis syndrome is the main syndrome associated with coronary heart disease (CHD), which bring difficulties in clinical treatment due to difficulties associated with differentiation of symptoms and signs. The fundamental differences of material between the two also need to be interpreted. The authors consider that we can use the method of combining a disease (in this case CHD) with associated syndromes (phlegm and blood stasis syndrome) to select patients with phlegm and blood stasis syndrome of CHD, and utilize metabonomics to explore the essence of the syndrome by difference analysis of metabolite spectra. Meanwhile, we can study the syndrome in CM, observe the change regularity of metabolism spectra after the treatment of corresponding and non-corresponding prescription and syndrome, in order to validate the material fundament in the progress of syndrome formation and their differences. This will not only have great significance in enhancing the ability to identify syndrome of phlegm and blood stasis in CHD and to establish the clinical curative criteria, but will also offer a new approach of studying the essence for a syndrome using metabonomics.

    We consider a modified gravity plus single scalar-field model, where the scalar Lagrangian couples symmetrically both to the standard Riemannian volume-form (spacetime integration measure density) given by the square root of the determinant of the Riemannian metric, as well as to another non-Riemannian volume-form in terms of an auxiliary maximal-rank antisymmetric tensor gauge field. As shown in a previous paper, the pertinent scalar-field dynamics provides an exact unified description of both dark energy via dynamical generation of a cosmological constant, and dark matter as a ''dust'' fluid with geodesic flow as a result of a hidden Noether symmetry. Here we extend the discussion by considering a non-trivial modification of the purely gravitational action in the form of f(R) = R -αR 2 generalized gravity. Upon deriving the corresponding ''Einstein-frame'' effective action of the latter modified gravity-scalar-field theory we find explicit duality (in the sense of weak versus strong coupling) between the original model of unified dynamical dark energy and dust fluid dark matter, on one hand, and a specific quadratic purely kinetic ''k-essence'' gravity-matter model with special dependence of its coupling constants on only two independent parameters, on the other hand. The canonical Hamiltonian treatment and Wheeler-DeWitt quantization of the dual purely kinetic ''k-essence'' gravity-matter model is also briefly discussed. (orig.)

  11. On the Essence of Space

    2003-04-01

    A new theory of space is suggested. It represents the new point of view which has arisen from the critical analysis of the foundations of physics (in particular the theory of relativity and quantum mechanics), mathematics, cosmology and philosophy. The main idea following from the analysis is that the concept of movement represents a key to understanding of the essence of space. The starting-point of the theory is represented by the following philosophical (dialectical materialistic) principles. (a) The principle of the materiality (of the objective reality) of the Nature: the Nature (the Universe) is a system (a set) of material objects (particles, bodies, fields); each object has properties, features, and the properties, the features are inseparable characteristics of material object and belong only to material object. (b) The principle of the existence of material object: an object exists as the objective reality, and movement is a form of existence of object. (c) The principle (definition) of movement of object: the movement is change (i.e. transition of some states into others) in general; the movement determines a direction, and direction characterizes the movement. (d) The principle of existence of time: the time exists as the parameter of the system of reference. These principles lead to the following statements expressing the essence of space. (1) There is no space in general, and there exist space only as a form of existence of the properties and features of the object. It means that the space is a set of the measures of the object (the measure is the philosophical category meaning unity of the qualitative and quantitative determinacy of the object). In other words, the space of the object is a set of the states of the object. (2) The states of the object are manifested only in a system of reference. The main informational property of the unitary system researched physical object + system of reference is that the system of reference determines (measures

    Full Text Available The aim of the article is to clarify the methodological basis for further research concerning analysis of the existing practices and development of proposals on using financial instruments for the modernization of the Ukrainian electric power sector, in particular, to clarify the definition of “financial instruments” and justify their classification, taking into account the defining characteristics. Based on the critical evaluation of various scientific approaches to interpretation of the essence of financial instruments, the author’s definition is proposed. Thus, it is advisable to consider them as means, techniques and methods of attracting financial resources (capital from other entities and as absolutely liquid assets. The generalization and rethinking of the criteria for classification of financial instruments allowed the authors to divide them into financial assets (cash, bank metals, currency, financial obligations (equity and debt instruments, and instruments of irrevocable financial aid (charitable contributions, grants, crowdfunding, fundraising. The received methodological conclusions quite fully characterize the essence and variety of types of financial instruments, taking into account their principal properties, which will allow to make a well-considered justification for choosing the optimal instruments for the modernization of the electric power sector.

    Investigation the multibody contact-sliding occurred at atomic discrete contact spot will play an important role in determine the origin of tribology behavior and evaluates the micro-mechanical property of nanomaterials and thus optimizing the design of surface texture. This paper carries out large scale parallel molecular dynamics simulation on contact-sliding at atomic scale to uncover the special physical essence. The research shows that some kind of force field exists between nanodot pair and the interaction can be expressed by the linear combination of exponential function while the effective interaction distance limited in 1 angstrom for nanodot with several tens of nanometer diameter. The variation tendency about the interaction force between nanodot array is almost the same between nanodot pairs and thus the interaction between two nanodot array can be characterized by parallel mechanical spring. Multibody effect which dominates the interaction between atoms or molecules will gradually diminish with the increasing of length scales.

    We study the correspondence between the interacting viscous ghost dark energy model with the tachyon, K-essence and dilaton scalar field models in the framework of Einstein gravity. We consider a spatially non-flat FRW universe filled with interacting viscous ghost dark energy and dark matter. We reconstruct both the dynamics and potential of these scalar field models according to the evolutionary behavior of the interacting viscous ghost dark energy model, which can describe the accelerated expansion of the universe. Our numerical results show that the interaction and viscosity have opposite effects on the evolutionary properties of the ghost scalar field models. (paper)

    Full Text Available Chicken essence (CE is a liquid nutritional supplement made from cooking whole chickens. In traditional Chinese medicine, CE is used to support health, promote healing, increase metabolism, and relieve fatigue. However, few studies have examined the effect of CE on exercise performance and physical fatigue. We aimed to evaluate the potential beneficial effects of CE on fatigue and ergogenic functions following physical challenge in mice. Male ICR mice were divided into four groups to receive vehicle or CE by oral gavage at 0, 845, 1690, or 4225 mg/kg/day for 4 weeks. Exercise performance and anti-fatigue function were evaluated by forelimb grip strength, exhaustive swimming time, and levels of physical fatigue-related biomarkers serum lactate, ammonia, glucose, and creatine kinase (CK after physical challenge. CE supplementation dose-dependently elevated endurance and grip strength. CE supplementation significantly decreased lactate, ammonia, and CK levels after physical challenge. Tissue glycogen content, an important energy source for exercise, was significantly increased with CE supplementation. In addition, CE supplementation had few subchronic toxic effects. The supplementation with CE can have a wide spectrum of bioactivities on health promotion, performance improvement and anti-fatigue.

    Full Text Available It is suggested in the paper that section 176 is too compendious in its drafting. A consequence of this is that the declared objectives of the CLR to make the law comprehensible and, therefore, accessible is undermined. It fails to capture the essence of the principles that have emerged from the case law on the no-conflicts rule and the corporate opportunity. Further, the differing approaches towards the determination of liability by the Court of Appeal in Bhullar, on the one hand, and the more open textured approach towards the issue in Pyke, illustrates the dichotomy of the case law surrounding the corporate opportunity doctrine which the language of section 176 fails to resolve.

Existence of cosmological scaling solutions restricts the Lagrangian of the scalar field φ. Choosing p=Xg(Xe λφ ), where X=-g μν ∂ μ φ∂ ν φ/2 with g any function of Xe λφ and defining some suitable transformations, we have constructed the dynamical system in different models of gravity: (i) Loop Quantum Cosmology (LQC), (ii) DGP brane world and (iii) RS II brane world. We have investigated stability of this dynamical system around the critical point for three gravity models and investigated the scalar-field dominated attractor solution in support of accelerated universe. The roles of the physical parameters have also been shown graphically during the accelerating phase of the universe. (orig.)

    2014-01-01

    Full Text Available The article shows the essence and evolution of the economic security notion. It shows that the “economic security” notion is based on a number of definitions and principles of “security”. It establishes that in the result of development of the post-industrial society and complication of social and state relations, this notion was used with economic orientation. It shows that nowadays economic security is understood as the state, in which such components as financial, information, socio-economic, institutional and legal, technical and technological, intellectual and personnel, power and ecological activity are in the states of “absence of threat”, “safety”, “protection from threats”, “protection”, “reliability”, “stability”, “rest”, “independence” and “within acceptable bounds”. Moreover, there is a system of prevention or reduction of impact of threats under controlled conditions. The article shows that economic security is a dynamic component of the economy, which adapts to the needs of the time. The current stage of the state development requires taking into account specific and address specific features of the object of study (for example, branch for ensuring economic security under conditions of appearance of negative phenomena of uncertainty and risk. The prospect of further studies is developing new systems of economic security with consideration of historical grounds and modern tendencies of development of economic relations.

    Topological effects typically discussed in the context of quantum physics are emerging as one of the central paradigms of physics. Here, we demonstrate the role of topology in energy transport through dimerized micro- and nanomechanical lattices in the classical regime, i.e., essentially "masses and springs." We show that the thermal conductance factorizes into topological and nontopological components. The former takes on three discrete values and arises due to the appearance of edge modes that prevent good contact between the heat reservoirs and the bulk, giving a length-independent reduction of the conductance. In essence, energy input at the boundary mostly stays there, an effect robust against disorder and nonlinearity. These results bridge two seemingly disconnected disciplines of physics, namely topology and thermal transport, and suggest ways to engineer thermal contacts, opening a direction to explore the ramifications of topological properties on nanoscale technology.

  3. The essence of frailty: A systematic review and qualitative synthesis on frailty concepts and definitions.

    One of the major threats looming over the growing older population is frailty. It is a distinctive health state characterised by increased vulnerability to internal and external stressors. Although the presence of frailty is well acknowledged, its concept and operationalisation are hampered by the extraordinary phenotypical and biological complexity. Yet, a widely accepted conception is needed to offer tailored policies and approaches. The ADVANTAGE Group aims to analyse the diverse frailty concepts to uncover the essence of frailty as a basis for a shared understanding. A systematic literature review was performed on frailty concepts and definitions from 2010 onwards. Eligible publications were reviewed using concept analysis that led to the extraction of text data for the themes "definition", "attributes", "antecedents", "consequences", and "related concepts". Qualitative description was used to further analyse the extracted text passages, leading to inductively developed categories on the essence of frailty. 78 publications were included in the review, and 996 relevant text passages were extracted for analysis. Five components constituted a comprehensive definition: vulnerability, genesis, features, characteristics, and adverse outcomes. Each component is described in more detail by a set of defining and explanatory criteria. An underlying functional perspective of health or its impairments is most compatible with the entity of frailty. The recent findings facilitate a focus on the relevant building blocks that define frailty. They point to the commonalities of the diverse frailty concepts and definitions. Based on these components, a widely accepted broad definition of frailty comes into range. Copyright © 2018 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

    Most research links (racial) essentialism to negative intergroup outcomes. We propose that this conclusion reflects both a narrow conceptual focus on biological/genetic essence and a narrow research focus from the perspective of racially dominant groups. We distinguished between beliefs in biological and cultural essences, and we investigated the implications of this distinction for support of social justice policies (e.g., affirmative action) among people with dominant (White) and subordinated (e.g., Black, Latino) racial identities in the United States. Whereas, endorsement of biological essentialism may have similarly negative implications for social justice policies across racial categories, we investigated the hypothesis that endorsement of cultural essentialism would have different implications across racial categories. In Studies 1a and 1b, we assessed the properties of a cultural essentialism measure we developed using two samples with different racial/ethnic compositions. In Study 2, we collected data from 170 participants using an online questionnaire to test the implications of essentialist beliefs for policy support. Consistent with previous research, we found that belief in biological essentialism was negatively related to policy support for participants from both dominant and subordinated categories. In contrast, the relationship between cultural essentialism and policy support varied across identity categories in the hypothesized way: negative for participants from the dominant category but positive for participants from subordinated categories. Results suggest that cultural essentialism may provide a way of identification that subordinated communities use to mobilize support for social justice.

    Full Text Available Diagnoses of autism spectrum disorder (ASD and attention-deficit/hyperactivity disorder (ADHD are increasingly being made in adulthood. However, assessments can fail to address the diverse range of problems that patients have experienced. The current study applied an early symptomatic syndromes eliciting neurodevelopmental clinical examinations (ESSENCE framework to explore retrospectively reported childhood developmental and behavioral problems. It examined if adult ASD and ADHD patients would show problems outside those reflected in the respective diagnostic criteria, and also if these patient groups would show more extensive childhood problems than other psychiatric patients. Parents of adults with ADHD (n = 130, ASD (n = 57, coexisting ADHD and ASD (n = 38, and other psychiatric disorders (n = 56 reported on a range of childhood problems. Descriptions of the ADHD, ASD, and ADHD+ASD groups reflected greater impairment than descriptions for patients with other psychiatric disorders in most problem areas. Although differences were observed between ADHD and ASD patients in the core diagnostic areas, these syndromes also shared a number of childhood difficulties. The ESSENCE approach can assist in understanding the symptom history of adult ADHD and ASD patients and can be helpful to distinguish their childhood experiences from other psychiatric patients' experiences.

    Essence of chicken (EOC) beverage is a chicken meat extract, widely consumed in Asian countries for health benefits. EOC is a rich source of peptides and amino acids. White bread has become a popular staple food in all regions of Southeast Asia. A randomized controlled, crossover, non-blind trial was performed to investigate the role of EOC on glycaemic response (GR) of white bread. Ten healthy young subjects returned on five separate days for three glucose and two bread sessions. Subjects consumed bread or bread with EOC. The 120 min incremental area under the curve was significantly lower after consuming two bottles of EOC with bread than white bread alone. The glycaemic index (GI) of white bread was 83 and white bread with EOC 57. The co-ingestion of EOC may be a practical and simple way to reduce the GR of bread and other starch-based staples.

Given that land management is a fundamental mechanism for land management and land use, in our opinion its reform and development should be seen in close relationship with the development of management system. Problems in the theory of management of land resources, especially its main land managers in different socio-economic communities is extremely important because the efficiency of its operation is not the most important in the economic relations of land ownership. However, for more than 25 years the implementation of land reform inUkrainegovernment has not decided as of model management and land management systems.

    Pot experiment studies on the fertility regulation and improvement of fertile and infertile brown earth type vegetable garden soils and their functionary essence show that under conditions of taking different soil fertility improvement measures, the nutrient contents in fertile and infertile soils were not always higher than the controls, but the aggregation densities of soil microaggregates were increased, and the proportion of different microaggregates was more rational. There was no significant relationship between soil productivity and soil microaggregates proportion. It is proved that the essence of soil fertility improvement consists in the ultimate change of the preservation and supply capacities of soil nutrients, and the proportion of soil microaggregates could be an integrative index to evaluate the level of soil fertility and the efficiency of soil improvement.

    Full Text Available The aim of this study was to carry out an ethnobotanical characterization of forest essences with medicinal properties used by the Xipaya ethnicity from Tukamã village in PA. For this, traditional methods for ethnobotanical surveys were used, such as the application of descriptive and qualitative questionnaires, Shannon-Wiener and Simpson diversity indexes, and Pielou’s evenness and agreement of main use (AMU indexes. The most cited botanical families were Fabaceae, Moraceae, Lecythidaceae, Euphorbiaceae, and Lauraceae. It was observed that the preparation methods weredifferent, and the parts of the plant that were used were also different. The Shannon-Wiener diversity index was 3.24. The Pielou’s evenness index was 0.97, and the Simpson diversity index was 0.04. All were considered significant. The species with precious bark (Aniba canelilla, red cedar (Cedrela odorata, Genipa (Genipa Americana, Pink Ipê (Tabebuia impetiginosa, Mulungu (Erythrina mulungu, Quassia (Quassia amara, and dragon's blood (Croton urucurana were unanimous regarding AMU. Therefore, we observed that the Xipaya community, from the Tukamã village, still hold enough information on medicinal forest essences, the women being the main key holders of these practices and thus contributing to the education, culture, and lifestyle of this community.

    In Germany, alternative medicine is presently very popular and is supported by the federal government. When deliberating on the essence of alternative medicine we should simultaneously reflect on the intellectual and moral basis of regular medicine. To provide an epistemological demarcation of the 2 fields, the following 12 theses are advanced: (1) alternative and regular medicine are speaking different languages; (2) alternative medicine is not unconventional medicine; (3) the paradigm of regular medicine is rational thinking; (4) the paradigm of alternative medicine is irrational thinking; (5) the present popularity of alternative medicine can be explained by romanticism; (6) some concepts of alternative medicine are falsifiable and others are not; (7) alternative medicine and evidence-based medicine are mutually exclusive; (8) the placebo effect is an important factor in regular medicine and the exclusive therapeutic principle of alternative medicine; (9) regular and alternative medicine have different aims: coming of age vs faithfulness; (10) alternative medicine is not always safe; (11) alternative medicine is not economic; and (12) alternative medicine will always exist. The fact that alternative methods are presently an integral part of medicine as taught at German universities, as well as of the physician's fee schedule, represents a collective aberration of mind that hopefully will last for only a short time.

    We investigate the physical properties of a purely kinetic k-essence model with an equation of state motivated in superconducting membranes. We compute the equation of state parameter w and discuss its physical evolution via a nonlinear equation of state. Using the adiabatic speed of sound and energy density, we restrict the range of parameters of the model in order to have an acceptable physical behavior. We study the evolution of the scale factor and address the question of the possible existence of finite-time future singularities. Furthermore, we analyze the evolution of the luminosity distance d{sub L} with redshift z by comparing (normalizing) it with the ΛCDM model. Since the equation of state parameter is z-dependent the evolution of the luminosity distance is also analyzed using the Alcock-Paczynski test. (orig.)

    We present constraints on the dark energy equation-of-state parameter, w = P/({rho}c{sup 2}), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE supernova survey. We derive a set of constraints on the nature of the dark energy assuming a flat Universe. By including constraints on ({Omega}{sub M}, w) from baryon acoustic oscillations, we obtain a value for a static equation-of-state parameter w = -1.05{sub -0.12}{sup +0.13} (stat 1{sigma}) {+-} 0.13 (sys) and {Omega}{sub M} = 0.274{sub -0.020}{sup +0.033} (stat 1{sigma}) with a best-fit {chi}{sup 2}/DoF of 0.96. These results are consistent with those reported by the Super-Nova Legacy Survey in a similar program measuring supernova distances and redshifts. We evaluate sources of systematic error that afflict supernova observations and present Monte Carlo simulations that explore these effects. Currently, the largest systematic currently with the potential to affect our measurements is the treatment of extinction due to dust in the supernova host galaxies. Combining our set of ESSENCE SNe Ia with the SuperNova Legacy Survey SNe Ia, we obtain a joint constraint of w = -1.07{sub -0.09}{sup +0.09} (stat 1{sigma}) {+-} 0.13 (sys), {Omega}{sub M} = 0.267{sub -0.018}{sup +0.028} (stat 1{sigma}) with a best-fit {chi}{sup 2}/DoF of 0.91. The current SNe Ia data are fully consistent with a cosmological constant.

    The purpose of this hermeneutic study was to investigate the essence of spirituality of terminally ill patients. In-depth unstructured interviews were used as the method for data collection. In the six-month period of data collection, the researcher was in the role of a hospice palliative care consultant who directly took care of the subject patients in a hospice ward of a teaching hospital. The six subjects were selected purposively according to various demographic backgrounds. Interview transcripts provided the data for analysis. The results were composed of four constitutive patterns and ten themes. The first constitutive pattern was "Communion with Self" which included three themes: (1) Self-identity--spirituality is the discovery of the authentic self. (2) Wholeness--a human being is full of contradictions but still in wholeness. (3) Inner peace--spirituality is negotiating conflicts for self-reconciliation. The second constitutive pattern was "Communion with others" which included two themes: (1) Love--spirituality is a caring relationship but not an over-attachment to others. (2) Reconciliation--spirituality is to forgive and to be forgiven. The third constitutive pattern was "Communion with Nature" which included two themes: (1) Inspiration from the nature--spirituality is the resonance of the marvelous beauty of nature. (2) Creativity--spirituality is conceiving imaginatively. The fourth constitutive pattern was "Communion with Higher Being" which included three themes: (1) Faithfulness--spirituality is keeping the trust dependably. (2) Hope--spirituality is claiming possibilities. (3) Gratitude--spirituality is giving thanks and embracing grace. The scientific rigor of this qualitative research as well as the strength and limitations of the study are reported. Implications for hospice palliative care and future research are recommended.

    The "cholera cloud" is one of the most persistent presences in the archives of nineteenth-century cholera in the "British World." Yet it has seldom received anything more than a passing acknowledgment from historians of cholera. Tracing the history of the cholera cloud as an object promises to open up a new dimension of the historically contingent experience of cholera, as well as make a significant contribution to the emergent literature on "thing theory." By conceptualizing the cholera cloud as an object-without-an-essence, this article demonstrates how global cholera pandemics in the nineteenth century produced globalized objects in which a near-universal recognizability and an utterly context-specific set of meanings, visions, and realities could ironically cohabit.

    Our long-standing scientific work and love to the fine art and nature for many years succeeded in making a unifying description of the three domains, at a time when a high specialisation in science, and even in art, has neglected the necessary entirety. Some neurons of a rat cerebral cortex were labelled with true blue and photographed under a fluorescent microscope. A monkey brain was sectioned in the axial plane. Several slices of the human motor cortex were stained with cresyl violet. A cerebral hemisphere image was modified, and another image was created in Adobe Photoshop. Some 10 billion years after the Big Bang life appeared on the Earth, reaching its peak with development of the brain. The humans started exploration of the local nature to survive, and the universe for psychological support. The antique philosophers Leucippes, Democritus and Heraclitus were the first to create a unifying atomic theory and to suggest the eternal movement of the matter. Newton and Kepler explained the movement of the celestial objects, whereas Einstein, Planck, Bohr, Hubbel, Howking and many others connected the quantum physics and elementary forces with the essence of the universe. Leonardo da Vinci, and later many others as well, united science and art. Philosophers and mathematicians created the phenomena which do not exist in nature. Nature designed the human brain, more complex than the universe itself, which in turn created millions of the artworks and scientific discoveries. The might of the mind in some domains overcomes the power of nature.

    2012-09-01

    Full Text Available I define information from a philosophical perspective as a category that indicates the presence of indirect existence, which is a self-display by material entities (with direct existence of the status and trajectory of that existence. In this paper, based in part on articles published only in Chinese over the last 30 years, information is shown to include three basic forms: In-itself, for-itself and regenerated information, which is constituted by the first two. Information in these three basic forms establishes the essence of information which is further developed in a fourth form—social information. Information is further characterized by the qualities of its three different grades, corresponding to these forms: The quality of first-grade information demonstrates direct objective existence and indirect objective existence; the quality of second-grade information demonstrates multiple levels of direct objective and indirect objective existence; the quality of third-grade information is that of the subjective relationships in human understanding that are encoded as information. The grounding of information in the ontological structure of the world gives it a central role in the approach to knowledge, constituting a new and necessary critique of the classical separation of the academic disciplines and the bases of modern philosophy.

An attention is drawn to the fact that the process of proof in criminal proceedings is not completed with a pre-court investigation, on the contrary, it is being continued even more actively during the court hearing. In this regard a need for providing of subjects of court hearings of criminal cases (judges, prosecuting attorneys, defense lawyers with criminalistic methods is emphasized. At the same time the stated ideas have not been sufficiently developed in Ukrainian doctrine. Special papers devoted to particular criminalistic methods of court hearing of criminal cases are not present.

    Full Text Available Introduction. Constant changes in the economic situation in the country and in the world give rise to new problems in asset management of commercial banks. This, in turn, requires the timely development and introduction of new and improved mechanisms for active operations of banking institutions. Only the implementation of such adequate mechanisms will allow, on the one hand, to satisfy the needs of consumers of banking services, and on the other – for banking institutions, to obtain the necessary level of profit for the acceptable risk to them. Purpose. Substantiation of theoretical foundations of organization and management of assets of banking institutions and determination of perspective directions of development of active operations in commercial banks. Results. The article provides a list of operations carried out by commercial banks of Ukraine. The essence of the concept of active operations of a banking institution as an important element of its activity for profit is considered. Possible variants of classification of active operations are analyzed, depending on the criterion underlying (risk level, liquidity and term of putting. The definition of a bank loan and its basic principles are given. The purposes and advantages of investment activity of banking institutions are specified, the classification of such activity is carried out. Proposed directions of development of active operations of banking institutions through the use of intermediary operations and unconventional banking services are offered. Conclusions. Currently, banking institutions carry out a large number of different banking operations. Mobilized by carrying out passive operations cash funds of the banking institution are placed through active operations in different directions. The basis of active operations of a commercial bank is its credit and investment operations. A commercial bank’s profits in the future are dependent on their effective conduct. The conduct of

CE company claimed that the health benefits were proven with research studies. A systematic review was conducted to determine the cognitive-enhancing effects of CE. We systematically searched a number of databases for randomized controlled trials with human subjects consuming CE and cognitive tests involved. Cochrane’s Risk of Bias (ROB tool was used to assess the quality of trials and meta-analysis was performed. Seven trials were included, where six healthy subjects and one subject with poorer cognitive functions were recruited. One trial had unclear ROB while the rest had high ROB. For executive function tests, there was a significant difference favoring CE (pooled standardized mean difference (SMD of −0.55 (−1.04, −0.06 and another with no significant difference (pooled SMD of 0.70 (−0.001, 1.40. For short-term memory tests, no significant difference was found (pooled SMD of 0.63 (−0.16, 1.42. Currently, there is a lack of convincing evidence to show a cognitive enhancing effect of CE.

    Full Text Available There is the urgent necessity of the transition to a higher level of economic relations in the system of environmental management in the present conditions of economy of the country. As a result, the issues like formation of information support for water rent management, determining the ways of its calculation, distribution as well as usage of water rents require urgent solutions. The study focuses on the essence of water rent and forming organizational and methodological provisions of its accounting reflection to ensure sustainable ecological and economic development of the enterprise. As a result of research the classification of water rent, that affects reflection of such rent in accounting has been formed. It is established that the amount of water rent for accounting reflection can be defined as the difference between actual and normal profit of enterprise-water users. A number of analytical accounts of first and second order as well as the typical correspondence of accounts for accounting reflection of water rent have been suggested. The information from the Report on the formation of water rent that contains data on the sources of payback of expenses incurred for the maintenance of water bodies and the impact of ecological condition of water body on the size of water rent has been suggested to be used in order to manage the size of water rent and expenses incurred to obtain it. Thus, determining the amount of water rent will allow management personnel to adjust the activity of the company in accordance with the strategic objectives of the company’s development regarding the profitability and compliance with the concept of sustainable development.

This article aims to identify the changes that have been the results of industrial development and it’s reflection in the development of rural residential areas. The main intention of this study is to analyze the special consequences (economic, social and anatomical of the industrial center of Kashan in the development of neighboring rural areas. The industrial center consists of three factories that are for making essence, making equipment for gardeners and distillers and the Barij Company. All of the above companies are called the Industrial Center of Barij Essence. It has employed 1050 workers from amongst whom 120 people were identified and the questionnaires were randomly distributed among these workers. To analyze the data based on the measurement variables, descriptive and analytic methods (T were used. The results showed that economically, having rural industries has led to an increase in the people’s intake of  calories, seeing more consumption in long lasting goods and more satisfaction in the native people of the area. In addition, there is more social involvement,  improvements in not wasting the residents’ free time, decreasing of  natives immigration out of the rural areas and finally anatomically, quantity and quality improvement in the rural houses.

    Full Text Available Tawhid (the belief in transcendent oneness or unity of divinity is the culmination of all Islamic teachings and has a special place in Islamic sciences. The unity of essence begins by the unity of existential necessity and ends in unity of existence as many theosophers and mystics suggest. This essay discusses unity of essence as understood by two Sadraean thinkers (Hakim Mudarres Zunuzi and Banu Amin according to Mulla Sadra's principles. Undoubtedly, these two theosophers have no discord as far as they speak about necessity of existence and unity of Necessary Existence. Dispute erupts when Banu voices her Sadraean sympathy with transcendent oneness of existence while Mudarres takes another position.       According to Sadra, the being which has no limitation whatsoever leaves no room for other being to come into existence and be its second or third and thus it is unique and uncountable. In this world, thus, there is no existence but one of which the rest are manifestations (Mulla Sadra, 1382, 67. This view which has been mentioned by Sadra in different positions is the very idea of individual unity of existence. It needs to be explained that in Mulla Sadra's works there are two accounts of effect: Existence in itself for something-else (relational existence Existence for something-else (copulative existence      At first sight which is thought to be elementary as compared to the second one, effect enjoys a reality and existence of its own the whole identity of which is though being related to and depended on cause and this dependency is its very essence and undetachable but the effect like the cause is counted among  beings. This is the position which is also held by Mudarres Zunuzi as to contingent beings (Mudarres Zunuzi, 1376: 357. He seem to have understood Mulla Sadra's words implying this very sense alone without presuming the possibility of a second sense. To put it otherwise, he has indeed fathomed effect's copulative

    Full Text Available The road-transport complex objectively reflects the essence of efficient transportation process which is carried out by transport facilities along the highways. The complex  emphasizes an equivalent contribution of transport facilities and highways in a unified transportation process. Efficiency of the state economy rigidly depends on availability of the developed and well-functioning network of highways. Countries with the developed economy which have generally finished creation of national highway networks continue to invest money in public road systems that stimulates development of industrial sectors, agriculture and trade, etc. Their progress and efficient functioning is possible only with the balanced, overall development of the road-transport complex of the country. Functioning of the road-transport complex is inextricable connected with the operation of automotive transport and road infrastructure. Interaction of these two components of the unified economic system is determined by technical characteristics of the automotive transport and transport and operational indices of  the highways. Development of methods for optimum organization of management for functioning of the road complex is considered as an important problem of the national economy while forming market economy mechanisms. Further growth of capital expenditures including  investments will be needed in order to ensure such road conditions that meet the requirements of modern and perspective road traffic. Management of the highway network conditions presupposes a selection of such set of regulatory impacts on road conditions which will allow to minimize expenses in the road-transport complex. Elaboration and realization of the most efficient repair measures serve as such regulatory impact. The purpose is achieved while solving the problem pertaining to minimization of expenses on  transportations in the road-transport complex in the process of the realization of the most

    Surgery, as a treatment, is a stressful experience. The anxiety is more severe in open-heart surgery patients due to its risk and complications. The present study aimed to determine the effect of lavender essence on the levels of anxiety and blood cortisol in candidates for open-heart surgery. This was a single-blind clinical trial, a random allocation study with a control group conducted on 90 candidates for open-heart surgery in two groups of study and control. The study and control groups inhaled two drops of lavender and distilled water for 20 min, respectively. Spielberger questionnaire was filled by the patients. A 2 ml blood sample was taken to measure the cortisol level and patients' vital signs were recorded before and after intervention. Data were analyzed by chi-square in the form of mean, SD, and frequency distribution, independent t-test, paired t-test, and analysis of covariance (ANCOVA), with a significance level of P = 0.05 to modify the pre-test scores. Results showed a significant reduction in mean anxiety score from 56.73 (5.67) to 54.73 (5.42) after intervention in the study group, compared to the control group [1.11 (1.17)] (P < 0.001). There was also a higher difference in cortisol level in the study group compared to the control group [1.88 (0.56) vs. 0.42 (0.45)]. ANCOVA test showed that the 10.8% variance in anxiety score and 69.6% decrease in blood cortisol resulted from inhalation of lavender. Results showed the positive effect of lavender essence on anxiety and blood cortisol level among the patients. Aromatherapy with lavender is suggested to be considered as a nursing intervention in clinical settings.

    Full Text Available The article is dedicated to the problem of an adequate understanding of the manipulative strategy in educational process of the modern school by the high school aged pupils. The topicality of the problem is connected with inadequate spread of manipulative interaction in all life spheres. The deficiency of the skill of expedient use of manipulation in pedagogical process as well as fixing manipulation as the main way of relation construction are the unfavorable variants of human development. There were characterized the main influence strategies in communication. There were cited the results of techniques and creative tasks that allow to reveal the understanding of essence of manipulative strategy and to study its functioning in the senior pupils’ communicative plane. The special authors’ attention was concentrated on determination of pedagogical conditions of mastering the experience of manipulative communication by the high school aged pupils. In the process of research there were determined the certain threatening moments: the significant part of senior pupils does not understand their own manipulative actions, but see it in surrounding people and is ready to aggressive response. The ability to use the ways of flexible, adaptive countermanipulation that allow retain communicative connections between pupils and teachers is not sufficiently developed in the pupils of high school age

    This paper reports a study, which explored the lived experiences of the essence in developing nursing students' professional competence. Nursing students experience a high level of stress due to unexpected, uncontrolled and uncertain aspects in the clinical learning environment. A purposeful sampling technique was used to select 18 participants from all second year students. Focus group interviews were conducted for collection of data. The data was analyzed by applying the Giorgi method of analyzing phenomenological data. Experience of responsibility is central to professional development. A secure relation with nurse consultants is the basis for learning. Students wish to see contexts and reach a holistic understanding. Continuous guidance as well as students' continuous supervision of patients is vital for understanding the larger context of care. Educators and professional nurses with supervision responsibility must display the knowledge and skills required to promote the development of nursing students' professional competence. This study also highlights the importance of the ethical dimension inherent in the concept of competence. Group supervision can offer an opportunity for students to address their experiences of their ability to deal with unfamiliar and existential demands of practice. These fundamental presuppositions comprise collective requirements for education and competence development in practice. Copyright 2009 Elsevier Ltd. All rights reserved.

    The clinical significance of progesterone receptor (PgR) expression in estrogen receptor-negative (ER-) breast cancer is controversial. Herein, we systemically investigate the clinicopathologic features, molecular essence, and endocrine responsiveness of ER-/PgR+/HER2- phenotype. Four study cohorts were included. The first and second cohorts were from the Surveillance, Epidemiology, and End Results database (n = 67,932) and Fudan University Shanghai Cancer Center (n = 2,338), respectively, for clinicopathologic and survival analysis. The third and fourth cohorts were from two independent publicly available microarray datasets including 837 operable cases and 483 cases undergoing neoadjuvant chemotherapy, respectively, for clinicopathologic and gene-expression analysis. Characterized genes defining subgroups within the ER-/PgR+/HER2- phenotype were determined and further validated. Clinicopathologic features and survival outcomes of the ER-/PgR+ phenotype fell in between the ER+/PgR+ and ER-/PgR- phenotypes, but were more similar to ER-/PgR-. Among the ER-/PgR+ phenotype, 30% (95% confidence interval [CI] 17-42%, pooled by a fixed-effects method) were luminal-like and 59% (95% CI 45-72%, pooled by a fixed-effects method) were basal-like. We further refined the characterized genes for subtypes within the ER-/PgR+ phenotype and developed an immunohistochemistry-based method that could determine the molecular essence of ER-/PgR+ using three markers, TFF1, CK5, and EGFR. Either PAM50-defined or immunohistochemistry-defined basal-like ER-/PgR+ cases have a lower endocrine therapy sensitivity score compared with luminal-like ER-/PgR+ cases (P defined basal-like ER-/PgR+ cases might not benefit from adjuvant endocrine therapy (log-rank P = 0.61 for sufficient versus insufficient endocrine therapy). The majority of ER-/PgR+/HER2- phenotype breast cancers are basal-like and associated with a lower endocrine therapy sensitivity score. Additional studies are needed

    Science, engineering and mathematics-related disciplines have relied heavily on a researcher's ability to visualize phenomena under study and being able to link and superimpose various abstract and concrete representations including visual, spatial, and temporal. The spatial representations are especially important in all branches of biology (in developmental biology time becomes an important dimension), where 3D and often 4D representations are crucial for understanding the phenomena. By the time biology students get to undergraduate education, they are supposed to have acquired visual-spatial thinking skills, yet it has been documented that very few undergraduates and a small percentage of graduate students have had a chance to develop these skills to a sufficient degree. The current paper discusses the literature that highlights the essence of visual-spatial thinking and the development of visual-spatial literacy, considers the application of the visual-spatial thinking to biology education, and proposes how modern technology can help to promote visual-spatial literacy and higher order thinking among undergraduate students of biology.

    Full Text Available This article explores the views on existence of medieval Muslim philosophers Avicenna (d. 1037 and Averroes (d. 1198, whose works followed closely the philosophy of Aristotle. In addition to the Aristotelian influence, which permeated all medieval Islamic philosophy, Avicenna and Averroes were also inspired by Islamic theology, known in Arabic as kalām. The distinction between essence and existence is one of the most central and controversial aspects of Avicenna’s philosophy, together with his claim that existence is an accident. Averroes in turn has a radically different conception of existence, identifying it with existing beings rather than considering it as something in itself. With the Latin translation of Avicenna’s metaphysical works in the 12th century, the Avicennian distinction went on to shape much of the debate on existence in medieval Scholastic philosophy and beyond. This article assesses the meaning of the distinction in Avicenna as well as Averroes’ criticism. In explicating their radically different views on existence, it also touches on later discussions concerning existence, for example the issue whether existence is a predicate, in the Modern Age.

    El presente artículo explora las percepciones sobre la existencia de los filósofos medievales musulmanes Avicena (m. 1037 y Averroes (m. 1198, cuyas obras se encuentran muy próximas a la filosofía de Aristóteles.

La distinción entre esencia y existencia es uno de los más fundamentales y controvertidos aspectos de la filosofía de Avicena junto a su aseveración de que la existencia es un accidente. Averroes, en cambio, concibe de forma radicalmente diferente la existencia, identificándola con los seres existentes más que considerarla como algo en

    Full Text Available The article presents an analysis of the concept of «organizational culture» through the prism of a phenomenon of culture and different approaches to organizational culture are crystallizes. Culture is defined as historically certain level of society development and man, that expressed in the types and forms of human life organization, and material and spiritual values, which created by them. It is shown that one of the classifications of culture divided it into three types: monoactive (or linearly arranged, poliactive and reactive. Each of these types is characterized by a particular style of the information collection that defines the possibility of decisions making management when using this classification in organizations. The features of the interpretation of the concept of «organizational culture» are defined. The essence of the organizational culture is a set of values, which are the guidelines of behavior of employees, management decision-making guidelines, as well as a system of symbols and rituals that serve as a set of rules approved behavior of employees in an organization. Marked constituent elements of organizational culture: system of values, leadership style, the characters of organization, ceremonies and rituals, cultural organization’s network. The main characteristics of organizational culture are: universality, informality, stability. It is shown that the components of organizational culture changing in the conditions of globalization, which calls for new forms and methods of work with personnel in modern organizations.

    Full Text Available Background: The growing role of public transport and the pressure of economic criteria requires the new optimization tools for process of public transport planning. These problems are computationally very complex, thus it is preferable to use various approximate methods, leading to a good solution within an acceptable time. Methods: One of such method is the genetic algorithm mimicking the processes of evolution and natural selection in the nature. In this paper, the different variants of the public transport lines layout are subjected to the artificial selection. The essence of the proposed approach is a simplified method of calculating the value of the fit function for a single individual, which brings relatively short computation time even for large jobs. Results: It was shown that despite the introduced simplifications the quality of the results is not worsened. Using the data obtained from KZK GOP (Communications Municipal Association of Upper Silesian Industrial Region the described algorithm was used to optimize the layout of the network of bus lines located within the borders of Katowice. Conclusion: The proposed algorithm was applied to a real, very complex network of public transportation and a possibility of a significant improvement of its efficiency was indicated. The obtained results give hope that the presented model, after some improvements can be the basis of the scientific method, and in a consequence of a further development to find practical application.

    traitement s'explique par le fait que des methodologies completes existent dans le premier cas, depths plusieurs annees, alors qu'il est encore necessaire de regrouper et synthetiser des modeles et donnees eparses dans le second et ce pour estimer des impacts mal definis. Lors de l'estimation de la mortalite potentielle, il a pu etre demontre que les scenarios de pollution des eaux de boisson pouvaient etre negliges (delais d'alerte suffisants). Le nombre de victimes attribuables a la mise en jeu de la matiere serait d'environ 8 10{sup -2} annuellement (dont 75% parmi la population residente et 25% chez les automobilistes). Ce chiffre est superieur a celui des victimes de l'accident routier pour ce trafic (1 a 2 10{sup -2}), mais reste tres faible dans l'absolu. Ce nombre attendu de deces est une moyenne associee a des evenements assez rares (par an 1 chance sur 300 d'avoir un accident impliquant la matiere de facon catastrophique), alors que les accidents de circulation ont environ une chance sur sept d'arriver dans l'annee. Les 'effets dominos', c'est-a-dire l'interaction d'un accident de transport avec une installation fixe dangereuse, devraient augmenter ces indicateurs, mais l'analyse faite ici a ete essentiellement qualitative. La probabilite d'une pollution et donc d'une intervention importante est assez grande (environ 1 chance sur 12 par an). Celle d'un impact tres consequent est plus faible. En effet le risque de contamination de l'eau de boisson venant de la nappe est reduit car celle-ci est peu accessible au polluant et peu utilisee en aval des captages, c'est-a-dire la ou passe l'itineraire. Quant aux fleuves les chances d'un deversement direct sont 20 a 30 fois plus rares. Les consequences restent toutefois importantes puisque par exemple, avec it de phenol, on serait oblige de declarer l'eau comme non potable sur plus de 200 km environ. Si le niveau de risque semble satisfaisant, a condition que l'on accorde pas un poids trop fort aux catastrophes possibles

    Full Text Available Abstract Nowadays efforts to eradicate corruption become a global problem and not only as a national or regional issues. For a developing country like Indonesia has almost become a condition sine qua non. This research reviews the role of legal culture in formulating the legal awareness of the public in an effort to prevent corruption. This research is a sociolegal research leading to search ontologically. The type of research combines the empirical and normative studies. The outcomes of the research indicate that as an extraordinary crime corruption cases should be carried out in an extraordinary way. The consequence it is not only the financial loss of state but a crime that violates the rights of social and economic at large and systemic. Observing the criminal sanctions applicable in the law of corruption linked to the purpose of criminalization against perpetrators of corruption corruptor it can be seen that the essence of criminalization is intended as an attempt to eradicate corruption. But these efforts to date cannot be said to achieve its goals because that looks just taking measure have not been effective to minimize corruption. Criminalization efforts have not actually created the states role in protecting people against the corruption.

    Full Text Available Ajowan is one of the most important medicinal plants in Zahedan region. Salinity and drought are the main causes of yield reduction of plants in Sistan and Balochestan. To evaluate the effect of salinity on yield and quality of ajowan a factorial experiment with randomized complete block design with three replications was conducted at the greenhouse of the Payam Noor University of Agriculture in Zahedan in 2016. Treatments were two populations of ajowan: C1: local and C2: Pakistani which were considered as the first factor and five salinity levels 0, 2, 4, 6 and 8 d/ms as the second. The results of this experiment showed that highest root length, stem height, plant fresh weight and plant dry weight and yield of essence belonged to local population under saline condition. Increasing salinity levels beyond 4 ds/ms decreased quantitative traits significantly but increased essential oil content and concentrations of osmotic regulants (prolin and carbohydrate as compared to that of control. This may indicate that ajowan is tolerant to salinity.

    Full Text Available Summary. In the beginning of the article is defined a rational sequence of the consideration of the nature of the strategy of a company development, included into an integrated structure. Further the article describes the following items separately: "a strategy", "a development of a company", and "an integrational structure", applying them to companies included to the integrated structure; separating them from a strategy of development of an autonomous company. The article defines functions which such strategy must define, taking into consideration the nature of the strategy of the company development, included into an integrated structure. Next, the article defines six steps which describe a sequence of development of the strategy of the company development, included into an integrated structure. The analysis which is defined in the article allows determining a complete definition of essence of the strategy of the company development, included into an integrated structure. The article also defines a place of the strategy of development into the hierarchical structure of the strategies. The strategy of the company development, included into an integrated structure (as well as the strategy of development of an autonomous company -- is a competition strategy, and it separates "strategy of leadership for costs", “differentiation strategy”, and “strategy of focusing for costs”. Also authors are analyzed the strategy of the cost optimization. According to the complex definition of the strategy, and the strategy's place inside the hierarchical structure, the article defines functions which corporate, competitive, and functional strategies execute during the management of companies inside an integrational structure. The article presents characteristics of applied strategic decisions at different levels of all three types of strategies. The article's researches allow companies included to the integrated structure define their place inside the

    Full Text Available The article is dedicated to critical analysis of competitive conceptual approaches to determining the essence of financial system. The system establishing element of the financial system resource concept is understanding finance as economic relations of formation, allocation and use of financial resource funds with the purpose of performing functions and tasks of the state/company and provision of conditions for expanded reproduction. According to this approach, the notion «financial system» is further determination of finance and shall be interpreted as the totality of relatively separated but mutually related spheres and links of relations, in the process of which centralized and decentralized financial resource funds are created and used. The institutional concept of the financial system considers finance as a social institution that organizes determined ways of interactions between individuals or their separate groups in the society. Its target purpose is to minimize transaction expenses arising at exchange of binding requirements for real resources in the economy. Under this approach, the financial system is understood as an aggregate of means — financial institutions and markets — which result from the evolution of social contracts and with the help of which intertime decisions and interactions are fulfilled and coordination of savings and investments in the economy is performed. The article shows that the alternative theoretical models of financial system contain structural elements heterogeneous by content and nature of interrelations, with various properties. The differences between them concern methodological approach to distinguishing qualitative signs which determine the essential nature and structure of the financial system; mechanism of formation and functioning of financial relations; nature of distribution and scheme of financial resources flow; the nature of functions of the financial system in the economic environment

    Pyroelectric response mechanism of Ba 0.70 Sr 0.30 TiO 3 ceramics under dielectric bolometer (DB) mode was investigated by dielectric and pyroelectric properties measurement. The variations of total, intrinsic, and induced pyroelectric coefficients (p tot , p int , p ind ) with temperatures and bias fields were analyzed. p int plays the dominant role to p tot through most of the temperature range and p ind will be slightly higher than p int above T 0 . The essence of the enhancing effect of DC bias field on pyroelectric coefficient can be attributed to the high value of p int . This mechanism is useful for the pyroelectric materials (DB mode) applications.

En effet, l’activité de conduite est une activité de travail et le risque qui lui est lié est un risque au travail. Pour prévenir ce dernier, il est donc nécessaire de dépasser la simple approche comportementale de l’activité de conduite et de prendre en considération l’ensemble des déterminants de l’activité de travail qui font que le conducteur de travaux se déplace et prend des risques sur la route. Nous retiendrons que les aspects organisationnels (prescription, organisation de la production, politique de ressources humaines, matériel (véhicule, outils de communication et interentreprises (relationnel client affectent l’activité de conduite et que la prévention du risque routier nécessite donc une approche globale (aux niveaux individuel et collectif, dans l’entreprise et avec les entreprises extérieures qui touche à ces différents domaines.This paper presents the results of a study on the occupational road risk of workers for whom driving is not their job but who drive frequently: Public Works site supervisors.

In fact, driving is a work activity and the related risk is an occupational risk. To prevent the latter, it is necessary to go beyond the simple behavioural driving activity approach and consider all the determinants of the work activity that cause the work supervisor to drive and take risks on the road

  8. A novel explicit approach to model bromide and pesticide transport in soils containing macropores

    The present study tests whether an explicit treatment of worm burrows is feasible for simulating water flow, bromide and pesticide transport in structured heterogeneous soils. The essence is to represent worm burrows as morphologically connected paths of low flow resistance in the spatially highly resolved model domain. A recent Monte Carlo study (Klaus and Zehe, 2010) revealed that this approach allowed successful reproduction of tile drain event discharge recorded during an irrigation experiment at a tile drained field site. However, several "hillslope architectures" that were all consistent with the available extensive data base allowed a good reproduction of tile drain flow response. Our second objective was thus to find out whether this "equifinality" in spatial model setups may be reduced when including bromide tracer data in the model falsification process. We thus simulated transport of bromide and Isoproturon (IPU) for the 13 spatial model setups, which performed best with respect to reproduce tile drain event discharge, without any further calibration. All model setups allowed a very good prediction of the temporal dynamics of cumulated bromide leaching into the tile drain, while only four of them matched the accumulated water balance and accumulated bromide loss into the tile drain. The number of behavioural model architectures could thus be reduced to four. One of those setups was used for simulating transport of IPU, using different parameter combinations to characterise adsorption according to the Footprint data base. Simulations could, however, only reproduce the observed leaching behaviour, when we allowed for retardation coefficients that were very close to one.

    Since the nutrition value of rice is diminished during rice processing, technology that can preserve and sustain functional compounds is necessary. In this study, supercritical carbon dioxide (SC-CO2) extraction was optimized for operational conditions (time, temperature, pressure and modifier) to extract vitamin E, γ-oryzanols and xanthophylls from rice bran. The simultaneous quantification of the compounds was developed using high-performance liquid chromatography with diode array and fluorescence detectors. Central composite design and respond surface methodology were applied to achieve optimum extraction conditions. The optimized conditions were 60min, 43°C, 5420psi with 10% ethanol as a modifier. Pigmented rice bran extracts contained greater amounts of functional phytochemicals than non-pigmented rice bran extracts (0.68, 1410, and non-detectable μg/g compared with 16.65, 2480, and 0.10μg/g of vitamin E, γ-oryzanols and xanthophylls in pigmented and non-pigmented ones, respectively). SC-CO2 extraction with modifier would be promising for preparation of phytochemical essences for therapeutic purpose. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2004-01-01

    A lot of Indian research is replicative in nature. This is because originality is at a premium here and mediocrity is in great demand. But replication has its merit as well because it helps in corroboration. And that is the bedrock on which many a fancied scientific hypothesis or theory stands, or falls. However, to go from replicative to original research will involve a massive effort to restructure the Indian psyche and an all round effort from numerous quarters.The second part of this paper deals with the essence of scientific temper,which need not have any basic friendship, or animosity, with religion, faith, superstition and other such entities. A true scientist follows two cardinal rules. He is never unwilling to accept the worth of evidence, howsoever damning to the most favourite of his theories. Second, and perhaps more important, for want of evidence, he withholds comment. He says neither yes nor no.Where will Science ultimately lead Man is the third part of this essay. One argument is that the conflict between Man and Science will continue tilleither of them is exhausted or wiped out. The other believes that it is Science which has to be harnessed for Man and not Man used for Science. And with the numerous checks and balances in place, Science will remain an effective tool for man's progress. The essential value-neutrality of Science will have to be supplemented by the values that man has upheld for centuries as fundamental, and which religious thought and moral philosophy have continuously professed.

    Full Text Available Direct injection of gasoline is a promising concept to reduce fuel consumption of SI engines. The development of GDI engines is difficult and 3D CFD is a way to support its design. It requires models able to describe the spray and its evaporation and combustion. This paper presents a model, the ECFM, that enables to compute combustion for stratified load in the GDI engines. This model is a development of the Coherent Flame Model which includes thermal expansion effects, and is coupled with a burnt/unburnt gases conditionnal thermodynamic properties description. The model is validated by comparing measurements and computations on the GDI Mitsubishi engine in production. L'injection directe d'essence (IDE est un concept prometteur pour les moteurs à allumage commandé. La mise au point de ce type de moteur est néanmoins délicate, et le calcul 3D des chambres de combustion est un moyen d'aider à leur conception. Ceci nécessite cependant de disposer de modèles adaptés, à même de décrire le jet d'essence, son évaporation et la combustion du mélange créé. Cet article présente un modèle ECFM de simulation de la combustion dans les moteurs IDE, y compris en fonctionnement stratifié. C'est un développement du modèle flamme cohérente qui comprend des effets d'expansion thermique et est couplé avec une description conditionnelle gaz frais/gaz brûlés des grandeurs thermodynamiques. Ce modèle a été validé par rapprochement de mesures et simulations sur le moteur GDI Mitsubishi.

    Full Text Available Dans les régions alpines, deux intérêts contradictoires coexistent. Une part de la population se plaint du manque d’accessibilité et de mobilité, l’autre part de la population est correctement desservie par les axes routiers internationaux mais en subit des nuisances importantes. Ces régions argumentent qu’une bonne part de ces transports est superflue, voire inutile. Cet article rend compte d’une étude qui s’est intéressée aux points suivants : 1 - Est-ce que des transports superflus ou inutiles pourraient être déplacés sans être remplacés ? 2 - Est-ce que les politiques fondées sur des redistributions modales ou sur le marché, comme la tarification des passages, sont suffisantes pour réduire les transports et leurs impacts ? 3 - Sous quelles conditions le transport peut-il être réduit de la manière la plus complète ? Des réponses sont proposées ici en analysant trois champs pertinents pour comprendre l’augmentation du trafic : la logique politique, la logique économique, et la logique de développement spatial. Ces logiques sont interprétées selon une approche régulationiste. Chacune a son application en terme d’arguments normatifs. Néanmoins, il y a des contradictions entre les différents objectifs sociétaux et/ou politiques et les objectifs économiques, et plus particulièrement entre la recherche de compétitivité et le respect de conditions de vie équitables entre les différentes régions. De telles contradictions peuvent être expliquées par les processus d’unification européenne, par les intérêts divergents entre les acteurs majeurs et par les changements de valeur des trente dernières années, qui peuvent être caractérisés comme un changement de régime. Les trois logiques sont le fruit de rapports sociaux et sont donc sujettes à des changements sur le long terme par les acteurs.

    Emergency response capabilities have been improved immensely; however, efficiency can be improved. Emphasis on the need for continuing response planning by governmental agencies and the need for improved coordination between all levels of government is required. Identification of resources (both personnel and equipment) available in each agency and in each respective governmental level and the means of securing available resources is imperative to minimize the effects of transportation incidents and accidents. In an effort to alleviate some of these problems, the Department of Energy has developed a program to make its contractors more aware of information currently available to assist them and first responders. The two major aspects of this program are: training transportation information resource availability. Improved awareness of information or training materials currently available for first responders and improved understanding of lessons learned will hopefully have an impact on the nuclear industry's ability to provide better response in the future

Contemporary designer does not need to have the knowledge needed to understand the essence of its all requirements that are placed on parts of the body. It is only important that they are aware of their existence and know who in the company can help them in their fulfilment of the construction. Nowadays, only the constructor creates a CAD model geometry, which is assumed to provide the functionality. The rest of the aspects such as the provision of adequate stiffness, manufacturability, assembly features, vibration analysis, etc., are the arena of other specialists. This is the essence of constructing simultaneous, where many cell companies often work on the same element, giving it a set of features impossible to obtain by one expert on everything. Therefore, the role of the designer is often limited to being only a CAD system operator.

    Full Text Available Marina Fiorato’s The Glassblower of Murano (2008 tells the story of Eleonora, a young woman who travels to Venice in search of her genealogical past and existential roots. Coming from London, Eleonora incarnates a “modern” outlook on what she assumes to be the timeless life and culture of Venice. At one point in the novel, admiring the old houses on the Canal Grande, Eleonora is “on fire with enthusiasm for this culture where the houses and the people kept their genetic essence so pure for millennia that they look the same now as in the Renaissance” (2008, 15. This discourse of pure origins and unbroken continuities is a fascinating fantasizing on characteristics that extend from the urban territory to the people who inhabit it. Within narratives centred on this notion, Italian culture, perceived as holding a privileged relation with history and the past, is often contrasted with the displacement and rootlessness that seem to characterize the modern places and people of England and North America. Through a discussion of two Anglo-American popular novels set in Italy, and several relocation narratives, this paper proposes an exploration of the notion according to which history is the force cementing the identities of societies perceived as less modern and frozen in a timeless dimension. From a point in time when the dialectics of history have been allegedly transcended, Anglo-American popular narratives observe Italy as a timeless, pre-modern other.

    Full Text Available The subject of the study is a set of theoretical, organizational, and methodological principles for the development of forensic accounting in Ukraine. General scientific and special methods of cognition are the methodological basis of the study. The content of the concept “forensic accounting” is specified using theoretical generalization methods; the comparison of audit and forensic accounting using comparison method is carried out. Using the abstract-logical method and structural-logical analysis, features, current problems, and obstacles to the development of forensic accounting in Ukraine are determined. The objective of the study is to consider the essence of the concept of “forensic accounting”, to introduce the main obstacles, and to propose a list of measures for its development in Ukraine. As a result of the study, it is established that forensic accounting is a combination of legal and financial audit and forensic accounting expertise. Therefore, experts of all these profiles should be involved to the forensic accounting, which will help the company solve the conflict situations related to fraud. It is substantiated that when improving the method of forensic accounting, it is necessary to understand its difference from the audit. The study found that the most common types of fraud faced by Ukrainian companies are asset theft, unreasonable and inappropriate spending. The most common ways to detect fraud in Ukraine are internal audit and informal internal sources. Only 10% of Ukrainian companies have experience in attracting external consultants to independent investigations. However, as practice shows, the very independent, unbiased view of the external specialist on the control system and business processes allows creating a high-quality system of preventive mechanisms for counteracting fraudulent actions and in general, improving the efficiency of business processes of the company. It is substantiated that forensic accounting

    Full Text Available The article is devoted to the essence and distinctive features of informational war as phenomenon which exists from the old times and became a global resource today. The methods and the tools of informational fight are an integral part of the military conflicts and might result with the tragic outcomes.  The problem of informational war in Ukraine and its background have been studied. The author argues that informational attacks against Ukraine have started long ago. They are aimed at loosening of the situation inside the country and creation of a negative image of Ukraine abroad. Pushing of idea of federalization, speculations on Russian as the second official language, the problems of Crimea and Crimea Tatars, allegations of illegal weapons trade during the war between Georgia and Russia, etc. are the examples of Russian informational attacks. The author analyzed the methods and the tools of informational influence used by Russian Federation against Ukraine. The author argues that Russia fights informational war openly andspending huge funds. There were described the main directions and the means of manipulative and psycho­informational technologies of Russian Federation towards Ukraine. The author has suggested the approaches to defense of informational space and national security of Ukraine.

La biomasse utilisee a des fins domestiques ne peut continuellement assurer aux menages, l approvisionnement energetique necessaire a la cuisson des aliments. Quant aux residus agro- industriels, ils ne peuvent reduire la consommation industrielle de produits petroliers.

    Full Text Available There are close links between air transport and international tourism. The latter, in a significant way has an impact on the development and stimulation of changes in aviation and, in particular, this applies to establishing new routes or increasing competition by the emergence of new air carriers. The essence of aviation is manifested in the aviation business travel and learning about the new States. Therefore, a change that has been made in aviation in the second half of the 20th century is a breakthrough. It is about a liberalization of this sector, which has enabled the development of international tourism. There are plenty of benefits for the development of tourism coming from the liberalization of aviation sector. Thanks to competitive prices and continually increasing offer of air connections to various places in the world, demand for tourism is growing trend. Among the factors hampering the development of aviation tourism, the following should be included: maintaining the visa requirement for many countries, the threat of terrorist attacks, a set of factors in the structure of tourism and safety issue. When it comes to Europe, along with the implementation of the common policy of the European Union, the sector of the tourism industry started to develop. Eliminating internal barriers and the gradual implementation of the freedom of movement of persons, services and capital has led to an increase in the demand for tourism in the EU. Europe is an attractive tourist destination in the world.

Dans cet article, nous proposons d’analyser de manière approfondie ce document pour comprendre la controverse fondatrice qui a justifié les travaux du futur métro à Bruxelles. En faisant parler les archives institutionnelles, nous soutenons que le métro bruxellois peut être considéré comme le résultat d’un compromis entre les deux institutions à l’époque en charge de la mobilité à Bruxelles : le Ministère des Travaux Publics et le Ministère des Communications. Préférant répondre aux normes de capacité et de rapidité déjà présentes dans le monde routier, le transport public a ainsi fait le deuil de la surface et, par là, a purifié le débat des mobilités urbaines en une solution apparemment strictement technique, espace pacifié où protagonistes d’un champ désormais commun peuvent s’entendre et s’allier.In 1963 the Belgian Ministry of Communications published a document entitled “Promotion des Transports en commun dans les grandes agglomérations”, real plea for the defence of public transport on the scale of five Belgian cities.

    Full Text Available El carácter sistémico del ferrocarril es consustancial a tan importante modo de transporte, pero no ha sido siempre bien comprendido. La noción de red es conocida por la Economía del Transporte y supone considerar ciertos principios y características de las redes que explican las particularidades de las industrias en red, incluido el ferrocarril. En el ámbito del Derecho, se parte de una previsión constitucional ajena a la realidad ferroviaria. Luego se han desarrollado categorías jurídicas específicas, como las infraestructuras en red, pero dichas construcciones dogmáticas parten de una equiparación entre infraestructura y red que se estima inadecuada o reduccionista. Finalmente, el concepto de red ha sido asumido por el Tribunal Constitucional como elemento funcional que permite delimitar las competencias sobre el ferrocarril, superando criterios formalistas alejados de la realidad. Se concluye que cualquier política sectorial o análisis jurídico del ferrocarril debe tomar en consideración su condición sistémica. Rail network and rail transports. Their systemic nature and required coordination between Territorial Administrations Systemic nature of railways is of essence but it has not always been properly understood. Network concept is well known for Transport Economics, it implies certain networks principles and characteristics showing the mechanics of network industries, such as railways. As far a Law is concerned, there is an inadequate constitutional regulation. Later on a specific legal category has been produced, network infrastructures, but it is based in the equivalence between infrastructures and networks, which it is deemed inadequate and reductionist. Finally, the network concept has been assumed by the Constitutional Court, as a functional element to narrow the powers on railways, overcoming any formalist criteria divorced for the reality. In conclusion any sectoral policy or legal analysis of railways must take

    Work-related stress (WS) can result in considerable and extensive changes in physiological and psychological performance. WS beyond the optimal levels induces anxiety, confusion, exhaustion, and burnout. Chronic WS affects neurocognitive performance, particularly attention and visuospatial memory. Essence of chicken (EC) has been reported to improve neurocognitive function after mental stress.To investigate the beneficial effects of EC in improving neurocognitive performance under WS, we conducted a randomized, double blind trial. Total 102 young workers in New Taipei City with high WS, evaluated using the Individual Subjective Perception Job Stress Scale scores (>36 for job leaders and 33 for nonleaders) were recruited. Fifty-one participants received 70 mL of EC and 51 received a placebo daily for 2 weeks. Blood tests and neurocognitive assessment were performed before treatment, at the end of treatment, and 2 weeks after treatment.EC improved the performance of participants with high depression scores in the form-color associative memory test, used for assessing short-term memory. Although creatinine and glutamic-pyruvic transaminase (GPT) levels increased in week 2, but the levels returned to the baseline in week 4. Blood urea nitrogen (BUN) levels decreased in week 4.EC significantly improved short-term memory in participants with high WS and concomitant depressive mood, although it slightly increased GPT and creatinine levels and reduced BUN levels. The long-term treatment effects of EC warrant further investigation.

    Heavy ion beam transport through the containment chamber plays a crucial role in all heavy ion fusion (HIF) scenarios. Here, several parameters are used to characterize the operating space for HIF beams; transport modes are assessed in relation to evolving target/accelerator requirements; results of recent relevant experiments and simulations of HIF transport are summarized; and relevant instabilities are reviewed. All transport options still exist, including (1) vacuum ballistic transport, (2) neutralized ballistic transport, and (3) channel-like transport. Presently, the European HIF program favors vacuum ballistic transport, while the US HIF program favors neutralized ballistic transport with channel-like transport as an alternate approach. Further transport research is needed to clearly guide selection of the most attractive, integrated HIF system

    of sand comminution on Mars. A multiple-grain transport model using just the equations of grain motion describing lift and drag is impossible to develop owing to stochastic effects --the very effects we wish to model. Also, unless we were to employ supercomputing techniques and extremely complex computer codes that could deal with millions of grains simultaneously, it would also be difficult to model grain transport if we attempted to consider every grain in motion. No existing computer models were found that satisfactorily used the equations of motion to arrive at transport flux numbers for the different populations of saltation and reptation. Modeling all the grains in a transport system was an intractable problem within our resources, and thus we developed what we believe to be a new modeling approach to simulating grain transport. The CFA deals with grain populations, but considers them to belong to various compartmentalized fluid units in the boundary layer. In this way, the model circumvents the multigrain problem by dealing primarily with the consequences of grain transport --momentum transfer between air and grains, which is the physical essence of a dynamic grain-fluid mixture. We thus chose to model the aeolian transport process as a superposition of fluids. These fluids include the air as well as particle populations of various properties. The prime property distinguishing these fluids is upward and downward grain motion. In a normal saltation trajectory, a grain's downwind velocity increases with time, so a rising grain will have a smaller downwind velocity than a failing grain. Because of this disparity in rising and falling grain proper-ties, it seemed appropriate to track these as two separate grain populations within the same physical space. The air itself can be considered a separate fluid superimposed within and interacting with the various grain-cloud "fluids". Additional informaiton is contained in the original.

    Extension of European Union causes increase of free transfer of people and goods. At the same time they raised the problems associated with the transport, e.g. congestion and related accidents on roads, air traffic delays and more. To increase the efficiency and safety of transport, the European Commission supports the introduction of intelligent transport systems and services in all transport sectors. Implementation of intelligent transport systems and services in the road transport reduces accident frequency, increases the capacity of existing infrastructure and reduces congestions. Use of toll systems provides resources needed for the construction and operation of a new road network, improves public transport, cycling transport and walking transport, and also their multimodal integration with individual car transport.

    Full Text Available Transportation systems have to be considered and analysed as a whole while transportation demand, becoming as a natural outcome of socioeconomic and socio-cultural structure, is being evaluated. It is desired that transportation system, which will be selected for both passenger and freight transport, should be rapid, economic, safe, causing least harm to environment and appropriate for the conditions of a country. However, it is difficult for a transportation system to have all these properties. Every transportation system has advantages and disadvantages over each other. Therefore, comprehensive plans for future periods have to be prepared and how the sources of the country should be reasonably distributed among transportation systems must be investigated. Also, transportation plans have to be prepared to get coordinated operations among transportation systems while great investments are instituted in the entire country. There is no doubt that it is possible with combined transportation instead of concentration on one transportation system. Transportation policies in Turkey should be questioned since the level of highway transportation usage reaches to 95 % and level of sea transportation usage drops to less than 1 % in spite of being surrounded with sea in three sides of our land. In this paper, transportation systems and transportation policies in Turkey are evaluated in general and problems are analysed. Proposals are presented for the solutions of these problems.

    Full Text Available Maintenance of circadian rhythms is essential to many aspects of human health, including metabolism and neurological and psychiatric well-being. Chronic disruption of circadian clock function is implicated in increasing the risk of metabolic syndrome, cardiovascular events and development of cancers. However, there are little approaches to reinforce the function of circadian clock for prevention of these diseases. Essence of Chicken (EC is a nutritional supplement that is traditionally made by extracting water soluble substances derived from cooking the whole chicken. In this study, we found that dietary supplementation with EC enhanced circadian oscillation of glucocorticoid secretion in mice, and this was accompanied by enhancement of circadian oscillation in the adrenal expression of steroidogenic acute regulatory (StAR protein that mediates the rate-limiting step of glucocorticoid synthesis. Furthermore, EC facilitated re-entrainment of behavioral rhythm in mice when phase of the light–dark cycle was suddenly advanced. These results suggest that intake of EC has enhancement effect on circadian clock function in mice, which may contribute to sustain health and also offer new preventive strategies against circadian-related diseases.

    Transport modeling of toroidal plasmas is one of the most important issue to predict time evolution of burning plasmas and to develop control schemes in reactor plasmas. In order to describe the plasma rotation and rapid transition self-consistently, we have developed an advanced scheme of transport modeling based on dynamical transport equation and applied it to the analysis of transport barrier formation. First we propose a new transport model and examine its behavior by the use of conventional diffusive transport equation. This model includes the electrostatic toroidal ITG mode and the electromagnetic ballooning mode and successfully describes the formation of internal transport barriers. Then the dynamical transport equation is introduced to describe the plasma rotation and the radial electric field self-consistently. The formation of edge transport barriers is systematically studied and compared with experimental observations. The possibility of kinetic transport modeling in velocity space is also examined. Finally the modular structure of integrated modeling code for tokamaks and helical systems is discussed. (author)

    Natural light in the Cistercian churches is closely linked not only with the liturgical requirements at the “officium” but also with the canonical hours based on the "ora et labora" dictated by the Rule of St. Benedict. The Cistercian architecture, in its beginnings (12th century forward) is characterized by austerity, simplicity and the play of light and shadow that gives value to the monastic architectural space itself, making it perfect for a contemplative experience. In the Cistercian Monastery the church is the central piece of the monastic building. Nave, transept and apse are the main architectural components to which is added the choir. This paper contextualizes the importance and close connections of natural light, within the Cistercian Monasteries architecture. Thus the essence of daylight is analysed within the Church of the Monastery of S. Bento de Cástris, in Évora, Portugal. This former Monastery (13th - 19th centuries) includes the church, at the south-eastern corner which has not only a high choir, but also a low lateral choir (within the presbytery). Its unchanged exterior walls are made of solid masonry. Although the function of the walls is primarily structural, the windows allow the daylight to penetrate the space of the church. The church has two external façades facing northeast and southeast. The combined orientation effect of the church’s main axis and the sun trajectory determines how the sunlight reaches the interior of this architectural structure. This study presents the qualitative and quantitative analysis of the luminous environment in the church of S. Bento de Cástris, being the first based on the authors’ perception of the effect of the daylight within the different areas of the enclosed space. The appreciation of the spatial experiences was supported by quantitative daylight simulations that were conducted in selected areas within the space. With this paper is intended to contribute to the debate about the specificity

    The Transportation Institutional Plan, published in 1986 by the U.S. Department of Energy's Office of Civilian Radioactive Waste Management (OCRWM), defines a process for effective interaction among those who may be affected by transportation activities conducted under provisions of the Nuclear Waste Policy Act of 1982 (NWPA). The Plan describes formal mechanisms for identifying, addressing, and resolving specific transportation issues. An appendix to the Plan includes detailed discussion of the following transportation issues: (1) the transportation of defense waste; (2) prenotification; (3) physical and rail shipments; (4) highway routing; (5) rail routing; (6) inspection and enforcement for highway and rail shipments; (7) emergency response; (8) liability coverage for transportation to NWPA facilities; (9) cask design and testing; (10) overweight truck shipments; (11) rail service analysis; (12) mixture of transportation modes; (13) transportation infrastructure improvements; (14) OCRWM training standards; (15) transportation operational procedures; and (16) State, Tribal, and local regulation of transportation. The OCRWM's intent is to provide an open accounting of planning, to identify opportunities for public involvement in program activities, and to foster communication and negotiation in the cooperative development of a safe, efficient, and cost-effective NWPA transportation program

  15. A Process-Based Transport-Distance Model of Aeolian Transport

    2017-12-01

    We present a new approach to modeling aeolian transport based on transport distance. Particle fluxes are based on statistical probabilities of particle detachment and distributions of transport lengths, which are functions of particle size classes. A computational saltation model is used to simulate transport distances over a variety of sizes. These are fit to an exponential distribution, which has the advantages of computational economy, concordance with current field measurements, and a meaningful relationship to theoretical assumptions about mean and median particle transport distance. This novel approach includes particle-particle interactions, which are important for sustaining aeolian transport and dust emission. Results from this model are compared with results from both bulk- and particle-sized-specific transport equations as well as empirical wind tunnel studies. The transport-distance approach has been successfully used for hydraulic processes, and extending this methodology from hydraulic to aeolian transport opens up the possibility of modeling joint transport by wind and water using consistent physics. Particularly in nutrient-limited environments, modeling the joint action of aeolian and hydraulic transport is essential for understanding the spatial distribution of biomass across landscapes and how it responds to climatic variability and change.

  16. The transport forecast - an important stage of transport management

    2017-10-01

    The transport system is a powerful system with varying loads in operation coming from changes in freight and passenger traffic in different time periods. The variations are due to the specific conditions of organization and development of socio-economic activities. The causes of varying loads can be included in three groups: economic, technical and organizational. The assessing of transport demand variability leads to proper forecast and development of the transport system, knowing that the market price is determined on equilibrium between supply and demand. The reduction of transport demand variability through different technical solutions, organizational, administrative, legislative leads to an increase in the efficiency and effectiveness of transport. The paper presents a new way of assessing the future needs of transport through dynamic series. Both researchers and practitioners in transport planning can benefit from the research results. This paper aims to analyze in an original approach how a good transport forecast can lead to a better management in transport, with significant effects on transport demand full meeting in quality terms. The case study shows how dynamic series of statistics can be used to identify the size of future demand addressed to the transport system.

    The iSNB (implicit Schurtz Nicolai Busquet multigroup electron thermal transport method of Cao et al. is adapted into a Monte Carlo transport method in order to better model the effects of non-local behavior. The end goal is a hybrid transport-diffusion method that combines Monte Carlo Transport with a discrete diffusion Monte Carlo (DDMC). The hybrid method will combine the efficiency of a diffusion method in short mean free path regions with the accuracy of a transport method in long mean free path regions. The Monte Carlo nature of the approach allows the algorithm to be massively parallelized. Work to date on the method will be presented. This work was supported by Sandia National Laboratory - Albuquerque and the University of Rochester Laboratory for Laser Energetics.

  2. Boron transport in plants: co-ordinated regulation of transporters

    Science.gov (United States)

    Miwa, Kyoko; Fujiwara, Toru

    2010-01-01

    Background The essentiality of boron (B) for plant growth was established >85 years ago. In the last decade, it has been revealed that one of the physiological roles of B is cross-linking the pectic polysaccharide rhamnogalacturonan II in primary cell walls. Borate cross-linking of pectic networks serves both for physical strength of cell walls and for cell adhesion. On the other hand, high concentrations of B are toxic to plant growth. To avoid deficiency and toxicity problems, it is important for plants to maintain their tissue B concentrations within an optimum range by regulating transport processes. Boron transport was long believed to be a passive, unregulated process, but the identification of B transporters has suggested that plants sense and respond to the B conditions and regulate transporters to maintain B homeostasis. Scope Transporters responsible for efficient B uptake by roots, xylem loading and B distribution among leaves have been described. These transporters are required under B limitation for efficient acquisition and utilization of B. Transporters important for tolerating high B levels in the environment have also been identified, and these transporters export B from roots back to the soil. Two types of transporters are involved in these processes: NIPs (nodulin-26-like intrinsic proteins), boric acid channels, and BORs, B exporters. It is demonstrated that the expression of genes encoding these transporters is finely regulated in response to B availability in the environment to ensure tissue B homeostasis. Furthermore, plants tolerant to stress produced by low B or high B in the environment can be generated through altered expression of these transporters. Conclusions The identification of the first B transporter led to the discovery that B transport was a process mediated not only by passive diffusion but also by transporters whose activity was regulated in response to B conditions. Now it is evident that plants sense internal and external B

  4. Nonlocal transport in the presence of transport barriers

    Science.gov (United States)

    Del-Castillo-Negrete, D.

    2013-10-01

    There is experimental, numerical, and theoretical evidence that transport in plasmas can, under certain circumstances, depart from the standard local, diffusive description. Examples include fast pulse propagation phenomena in perturbative experiments, non-diffusive scaling in L-mode plasmas, and non-Gaussian statistics of fluctuations. From the theoretical perspective, non-diffusive transport descriptions follow from the relaxation of the restrictive assumptions (locality, scale separation, and Gaussian/Markovian statistics) at the foundation of diffusive models. We discuss an alternative class of models able to capture some of the observed non-diffusive transport phenomenology. The models are based on a class of nonlocal, integro-differential operators that provide a unifying framework to describe non- Fickian scale-free transport, and non-Markovian (memory) effects. We study the interplay between nonlocality and internal transport barriers (ITBs) in perturbative transport including cold edge pulses and power modulation. Of particular interest in the nonlocal ``tunnelling'' of perturbations through ITBs. Also, flux-gradient diagrams are discussed as diagnostics to detect nonlocal transport processes in numerical simulations and experiments. Work supported by the US Department of Energy.

    Currently, there are more than 800 well characterized human membrane transport proteins (including channels and transporters) and there are estimates that about 10% (approx. 2000) of all human genes are related to transport. Membrane transport proteins are of interest as potential drug targets, for drug delivery, and as a cause of side effects and drug–drug interactions. In light of the development of Open PHACTS, which provides an open pharmacological space, we analyzed selected membrane transport protein classification schemes (Transporter Classification Database, ChEMBL, IUPHAR/BPS Guide to Pharmacology, and Gene Ontology) for their ability to serve as a basis for pharmacology driven protein classification. A comparison of these membrane transport protein classification schemes by using a set of clinically relevant transporters as use-case reveals the strengths and weaknesses of the different taxonomy approaches.

  12. Modeling flow and solute transport at a tile drain field site by explicit representation of preferential flow structures: Equifinality and uncertainty

    Zehe, E.; Klaus, J.

    2011-12-01

    Rapid flow in connected preferential flow paths is crucial for fast transport of water and solutes through soils, especially at tile drained field sites. The present study tests whether an explicit treatment of worm burrows is feasible for modeling water flow, bromide and pesticide transport in structured heterogeneous soils with a 2-dimensional Richards based model. The essence is to represent worm burrows as morphologically connected paths of low flow resistance and low retention capacity in the spatially highly resolved model domain. The underlying extensive database to test this approach was collected during an irrigation experiment, which investigated transport of bromide and the herbicide Isoproturon at a 900 sqm tile drained field site. In a first step we investigated whether the inherent uncertainty in key data causes equifinality i.e. whether there are several spatial model setups that reproduce tile drain event discharge in an acceptable manner. We found a considerable equifinality in the spatial setup of the model, when key parameters such as the area density of worm burrows and the maximum volumetric water flows inside these macropores were varied within the ranges of either our measurement errors or measurements reported in the literature. Thirteen model runs yielded a Nash-Sutcliffe coefficient of more than 0.9. Also, the flow volumes were in good accordance and peak timing errors where less than or equal to 20 min. In the second step we investigated thus whether this "equifinality" in spatial model setups may be reduced when including the bromide tracer data into the model falsification process. We simulated transport of bromide for the 13 spatial model setups, which performed best with respect to reproduce tile drain event discharge, without any further calibration. Four of this 13 model setups allowed to model bromide transport within fixed limits of acceptability. Parameter uncertainty and equifinality could thus be reduced. Thirdly, we selected

    Directional cell-to-cell transport of functional molecules, called polar transport, enables plants to sense and respond to developmental and environmental signals. Transporters that localize to plasma membranes (PMs) in a polar manner are key components of these systems. PIN-FORMED (PIN) auxin efflux carriers, which are the most studied polar-localized PM proteins, are implicated in the polar transport of auxin that in turn regulates plant development and tropic growth. In this review, the regulatory mechanisms underlying polar localization of PINs, control of auxin efflux activity, and PIN abundance at PMs are considered. Up to date information on polar-localized nutrient transporters that regulate directional nutrient movement from soil into the root vasculature is also discussed. Copyright © 2017 Elsevier Ltd.

    2009-01-01

    Explanations for, and indirect evidence of, imperfections in the market for private passenger vehicle fuel economy suggest there is a reasonable case for combining fuel economy standards and fuel or carbon taxes to contribute to an energy policy that aims to reduce greenhouse gas emissions and improve energy security. Estimates of key elasticities, including the rebound effect, indicate that the positive and negative side-effects of fuel economy measures on transport activities and external costs are limited. However, an energy policy for transport does not replace a transport policy that aims to manage the main transport externalities including congestion and local pollution. Conventional marginal cost estimates and standard cost-benefit reasoning suggest that policies that address congestion and local pollution likely bring benefits at least as large as those from fuel economy measures. But the large uncertainty on the possible effects of greenhouse gas emissions constitutes a strong challenge for standard cost-benefit reasoning. Emerging results from methods to cope with this uncertainty suggest that policies to stimulate the widespread adoption of low-carbon technologies in transport are justified.

    It is demonstrated through the flux-force relationship in the neoclassical theory that when neoclassical transport fluxes are improved, the damping rate of the radial electric field of the zonal flow is reduced. This, in turn, leads to improved turbulent transport fluxes. Thus, two seemingly unrelated transport fluxes are intimately connected through the momentum equation, and the neoclassical flux-force relation. This also implies a method to improve turbulent transport by improving neoclassical fluxes

    The Halifax Regional Municipality (HRM) approved its first municipal planning strategy (MPS), in June 2006 that set the general framework for planning decisions over the next 20 years. The major objectives of this initiative are to manage a moderate level of population growth, minimize the environmental impact of that growth, and use it as a catalyst to make HRM more sustainable in all of its activities. Due to the dispersed nature of HRM and the diverse mix of its urban, suburban, and rural areas, the links between communities become a key focal point for sustainability measures. Transportation issues are central to many of HRM's current planning decisions and are a key component of the MPS. This report summarized the portion of the MPS that related to the development of functional transportation plans for HRM. The report also presented findings for eight key indicator categories that could be utilized to assess the sustainability of HRM's transportation system. These indicator categories include transport activity; energy consumption; greenhouse gas emissions; transportation emissions of air pollutants; land use and transportation; access to basic services; access to public transportation; neighbourhood quality of life; and household spending on transportation. The report also provided a quantitative assessment of the economic costs of passenger road transportation in HRM. The costing section provided estimates for 15 cost categories, many of which go unexamined in standard transportation accounting mechanisms. Last, a set of data and policy recommendations outlining ways to improve transportation monitoring in HRM as well as to advance the sustainability of HRM's transportation system as a whole were presented. Recommendations included: establishing settlement patterns and pedestrian or cycling-oriented infrastructure where more people could walk or cycle to work and amenities; increasing ridership by making transit accessible to a wider

  9. La mobilité quotidienne dans les grandes villes du monde : application de la théorie des réseaux bayésiens

    Directory of Open Access Journals (Sweden)

    2004-02-01

    Full Text Available À la frontière entre statistiques multivariées et intelligence artificielle, les réseaux bayésiens sont un puissant outil de modélisation de connaissance systémique. Une utilisation particulièrement intéressante est celle de la recherche des liens causaux entre variables dans une base de données. Dans cet article, nous analysons une base de données urbaines sur la mobilité quotidienne couvrant plus de cent grandes villes mondiales. À l'aide d'algorithmes de génération de réseaux bayésiens, nous avons produit deux réseaux reliant les variables et traduisant deux hypothèses différentes sur la hiérarchie causale entre elles. Si l’on introduit l’hypothèse que la mobilité détermine la structure urbaine, on crée alors un réseau qui  identifie la motorisation de la population comme étant une variable cruciale. Ce réseau s’avère plus probable que celui résultant de l’hypothèse opposée. En revanche, les deux réseaux concordent sur l’importance de l’offre de voirie rapide urbaine et de la vitesse moyenne du réseau routier dans l’explication du partage modal et des coûts et des externalités des transports urbains.

    The Trapped Gyro-Landau Fluid (TGLF) quasi-linear model [G. M. Staebler, et al., Phys. Plasmas 12, 102508 (2005)], which is calibrated to nonlinear gyrokinetic turbulence simulations, is now able to predict the electron density, electron and ion temperatures, and ion toroidal rotation simultaneously for internal transport barrier (ITB) discharges. This is a strong validation of gyrokinetic theory of ITBs, requiring multiple instabilities responsible for transport in different channels at different scales. The mystery of transport inside the ITB is that momentum and particle transport is far above the predicted neoclassical levels in apparent contradiction with the expectation from the theory of suppression of turbulence by E×B velocity shear. The success of TGLF in predicting ITB transport is due to the inclusion of ion gyro-radius scale modes that become dominant at high E×B velocity shear and to improvements to TGLF that allow momentum transport from gyrokinetic turbulence to be faithfully modeled.

  12. Canadian pipeline transportation system : transportation assessment

    International Nuclear Information System (INIS)

    2009-07-01

    In addition to regulating the construction and operation of 70,000 km of oil and natural gas pipelines in Canada, the National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. This report provided an assessment of the Canadian hydrocarbon transportation system in relation to its ability to provide a robust energy infrastructure. Data was collected from NEB-regulated pipeline companies and a range of publicly available sources to determine if adequate pipeline capacity is in place to transport products to consumers. The NEB also used throughput and capacity information received from pipeline operators as well as members of the investment community. The study examined price differentials compared with firm service tolls for transportation paths, as well as capacity utilization on pipelines and the degree of apportionment on major oil pipelines. This review indicated that in general, the Canadian pipeline transportation system continues to work effectively, with adequate pipeline capacity in place to move products to consumers who need them. 9 tabs., 30 figs., 3 appendices.

    2003-01-01

    During january and february 2003, a unique event concerning nuclear transport was reported and rated 1 on the INES scale. This event concerns the absence of a maintenance operation on a shipping cask. This shipping cask was used for several years for nuclear transport inside La-hague site before being re-assigned to transport on public thoroughfare. The re-assignment of the cask should have been preceded and conditioned by a maintenance operation whose purpose is to check the efficiency of its radiation shield. During this period 2 on-site inspections concerning the transport of nuclear materials were performed. (A.C.)

  18. Solutions to Improve Person Transport System in the Pitesti City by Analyzing Public Transport vs. Private Transport

    Science.gov (United States)

    Mihaela, Istrate; Alexandru, Boroiu; Viorel, Nicolae; Ionel, Vieru

    2017-10-01

    One of the major problems facing the Pitesti city is the road congestion that occurs in the central area of the city during the peak hours. With all the measures taken in recent years - the widening of road arteries, increasing the number of parking spaces, the creation of overground road passages - it is obvious that the problem can only be solved by a new philosophy regarding urban mobility: it is no longer possible to continue through solutions to increase the accessibility of the central area of the city, but it is necessary, on the contrary, to promote a policy of discouraging the penetration of vehicles in the city center, coupled with a policy of improving the connection between urban public transport and county public transport. This new approach is also proposed in the new Urban Mobility Plan of Pitesti city, under development. The most convincing argument for the necessity of this new orientation in the Pitesti city mobility plan is based on the analysis of the current situation of passenger transport on the territory of Pitesti city: the analysis of “public transport versus private transport” reveals a very low occupancy rate for cars and the fact that the road surface required for a passenger (the dynamic area) is much higher in the case of private transport than in the case of public transport. Measurements of passenger flows and vehicle flows on the 6 penetration ways in the city have been made and the calculations clearly demonstrate the benefits of an urban public transport system connected by “transshipment buses” to be made at the edge of the city, to the county public transport system. In terms of inter-county transport, it will continue to be connected to the urban public transport system by existing bus Station, within the city: South Bus Station and North Bus Station. The usefulness of the paper is that it identifies the solutions for sustainable mobility in Pitesti city and proposes concrete solutions for the development of the

    The recently developed paleoclassical transport model sets the minimum level of electron thermal transport in a tokamak. This transport level has proven to be in good agreement with experimental observations in many cases when fluctuation-induced anomalous transport is small, i.e. in (near-)ohmic plasmas in small to medium size tokamaks, inside internal transport barriers (ITBs) or edge transport barriers (H-mode pedestal). In this paper predictions of the paleoclassical transport model are compared in detail with data from such kinds of discharges: ohmic discharges from the RTP tokamak, EC heated RTP discharges featuring both dynamic and shot-to-shot scans of the ECH power deposition radius and off-axis EC heated discharges from the TEXTOR tokamak. For ohmically heated RTP discharges the T{sub e} profiles predicted by the paleoclassical model are in reasonable agreement with the experimental observations, and various parametric dependences are captured satisfactorily. The electron thermal ITBs observed in steady state EC heated RTP discharges and transiently after switch-off of off-axis ECH in TEXTOR are predicted very well by the paleoclassical model.

    The importance of endosome-to–trans-Golgi network (TGN) retrograde transport in the anterograde transport of proteins is unclear. In this study, genome-wide screening of the factors necessary for efficient anterograde protein transport in human haploid cells identified subunits of the Golgi-associated retrograde protein (GARP) complex, a tethering factor involved in endosome-to-TGN transport. Knockout (KO) of each of the four GARP subunits, VPS51–VPS54, in HEK293 cells caused severely defective anterograde transport of both glycosylphosphatidylinositol (GPI)-anchored and transmembrane proteins from the TGN. Overexpression of VAMP4, v-SNARE, in VPS54-KO cells partially restored not only endosome-to-TGN retrograde transport, but also anterograde transport of both GPI-anchored and transmembrane proteins. Further screening for genes whose overexpression normalized the VPS54-KO phenotype identified TMEM87A, encoding an uncharacterized Golgi-resident membrane protein. Overexpression of TMEM87A or its close homologue TMEM87B in VPS54-KO cells partially restored endosome-to-TGN retrograde transport and anterograde transport. Therefore GARP- and VAMP4-dependent endosome-to-TGN retrograde transport is required for recycling of molecules critical for efficient post-Golgi anterograde transport of cell-surface integral membrane proteins. In addition, TMEM87A and TMEM87B are involved in endosome-to-TGN retrograde transport. PMID:26157166

    The Used Fuel Disposition (UFD) Transportation Task commenced in October 2010. As its first task, Pacific Northwest National Laboratory (PNNL) compiled a list of structures, systems, and components (SSCs) of transportation systems and their possible degradation mechanisms during extended storage. The list of SSCs and the associated degradation mechanisms (known as features, events, and processes (FEPs)) were based on the list of used nuclear fuel (UNF) storage system SSCs and degradation mechanisms developed by the UFD Storage Task (Hanson et al. 2011). Other sources of information surveyed to develop the list of SSCs and their degradation mechanisms included references such as Evaluation of the Technical Basis for Extended Dry Storage and Transportation of Used Nuclear Fuel (NWTRB 2010), Transportation, Aging and Disposal Canister System Performance Specification, Revision 1 (OCRWM 2008), Data Needs for Long-Term Storage of LWR Fuel (EPRI 1998), Technical Bases for Extended Dry Storage of Spent Nuclear Fuel (EPRI 2002), Used Fuel and High-Level Radioactive Waste Extended Storage Collaboration Program (EPRI 2010a), Industry Spent Fuel Storage Handbook (EPRI 2010b), and Transportation of Commercial Spent Nuclear Fuel, Issues Resolution (EPRI 2010c). SSCs include items such as the fuel, cladding, fuel baskets, neutron poisons, metal canisters, etc. Potential degradation mechanisms (FEPs) included mechanical, thermal, radiation and chemical stressors, such as fuel fragmentation, embrittlement of cladding by hydrogen, oxidation of cladding, metal fatigue, corrosion, etc. These degradation mechanisms are discussed in Section 2 of this report. The degradation mechanisms have been evaluated to determine if they would be influenced by extended storage or high burnup, the need for additional data, and their importance to transportation. These categories were used to identify the most significant transportation degradation mechanisms. As expected, for the most part, the

    Jones, E.

    1990-01-01

    Over the past 25 years extensive federal legislation involving the handling and transport of hazardous materials/waste has been passed that has resulted in numerous overlapping regulations administered and enforced by different federal agencies. The handling and transport of hazardous materials/waste involves a significant number of workers who are subject to a varying degree of risk should an accident occur during handling or transport. Effective transportation training can help workers address these risks and mitigate them, and at the same time enable ORNL to comply with the federal regulations concerning the transport of hazardous materials/waste. This presentation will outline how the Environmental and Health Protection Division's Technical Resources and Training Section at the Oak Ridge National Laboratory, working with transportation and waste disposal personnel, have developed and implemented a comprehensive transportation safety training program to meet the needs of our workers while satisfying appropriate federal regulations. 8 refs., 3 tabs

  12. Causality and superluminal behavior in classical field theories: Applications to k-essence theories and modified-Newtonian-dynamics-like theories of gravity

    International Nuclear Information System (INIS)

    Bruneton, Jean-Philippe

    2007-01-01

    Field theories with Lorentz (or diffeomorphism invariant) action can exhibit superluminal behavior through the breaking of local Lorentz invariance. Quantum induced superluminal velocities are well-known examples of this effect. The issue of the causal behavior of such propagation is somewhat controversial in the literature and we intend to clarify it. We provide a careful analysis of the meaning of causality in classical relativistic field theories and stress the role played by the Cauchy problem and the notion of chronology. We show that, in general, superluminal behavior threatens causality only if one assumes that a prior chronology in spacetime exists. In the case where superluminal propagation occurs, however, there are at least two nonconformally related metrics in spacetime and thus two available notions of chronology. These two chronologies are on equal footing, and it would thus be misleading to choose ab initio one of them to define causality. Rather, we provide a formulation of causality in which no prior chronology is assumed. We argue that this is the only way to deal with the issue of causality in the case where some degrees of freedom propagate faster than others. In that framework, then, it is shown that superluminal propagation is not necessarily noncausal, the final answer depending on the existence of an initial data formulation. This also depends on global properties of spacetime that we discuss in detail. As an illustration of these conceptual issues, we consider two field theories, namely, k-essence scalar fields and bimetric theories of gravity, and we derive the conditions imposed by causality. We discuss various applications such as the dark energy problem, modified-Newtonian-dynamics-like theories of gravity, and varying speed of light theories

  13. Human love--the inner essence of nursing ethics according to Estrid Rodhe. A study using the approach of history of ideas.

    Science.gov (United States)

    Kangasniemi, Mari; Haho, Annu

    2012-12-01

    The aim of this study is to describe the idea pattern of nursing ethics in the textbook written by the Swedish nurse Estrid Rodhe (1911). The purpose is to increase understanding of the ideas in early written history of nursing ethics by using the method of history of ideas. A theoretical premise, but also a fascinating factor in this study, is that the ethics of one profession is always contextual in relation to current period. The historical context of Rodhe's time was a time of difficult societal circumstances in Europe. Nurses' work was demanding, but a distinctive feature was enthusiasm to develop nursing. Discussion of the moral issues of nursing was intense, and the characteristics of a good nurse consisted of being as altruistic and unselfish woman. Based on our analysis, the inner essence of Rodhe's idea pattern consists of human love. It is reflected in her ideas of calling-based altruism, virtuous woman as a personal reason for being a nurse and nurses' ethical duty to implementation and subservience. Rodhe's thinking reflects the conventions of her time. The role of personal moral characteristics of nurses was highlighted and not viewed as separable from the professional. Her textbook represented nursing knowledge of ethics written by a nurse and making her a pioneer of the early written history of nursing in general. Understanding the past helps us comprehend current issues in nursing and makes visible cultural values that form the basis for today and tomorrow. It also provides a possibility to observe the same fundamental features in spite of temporal distance. Here, the history of ideas is a beneficial and fruitful method to increase our understanding of nursing ethics. © 2012 The Authors.

  14. Transport in Halobacterium Halobium: Light-Induced Cation-Gradients, Amino Acid Transport Kinetics, and Properties of Transport Carriers

    Science.gov (United States)

    Lanyi, Janos K.

    1977-01-01

    Cell envelope vesicles prepared from H. halobium contain bacteriorhodopsin and upon illumination protons are ejected. Coupled to the proton motive force is the efflux of Na(+). Measurements of Na-22 flux, exterior pH change, and membrane potential, Delta(psi) (with the dye 3,3'-dipentyloxadicarbocyanine) indicate that the means of Na(+) transport is sodium/proton exchange. The kinetics of the pH changes and other evidence suggests that the antiport is electrogenic (H(+)/Na(++ greater than 1). The resulting large chemical gradient for Na(+) (outside much greater than inside), as well as the membrane potential, will drive the transport of 18 amino acids. The I9th, glutamate, is unique in that its accumulation is indifferent to Delta(psi): this amino acid is transported only when a chemical gradient for Na(+) is present. Thus, when more and more NaCl is included in the vesicles glutamate transport proceeds with longer and longer lags. After illumination the gradient of H+() collapses within 1 min, while the large Na(+) gradient and glutamate transporting activity persists for 10- 15 min, indicating that proton motive force is not necessary for transport. A chemical gradient of Na(+), arranged by suspending vesicles loaded with KCl in NaCl, drives glutamate transport in the dark without other sources of energy, with V(sub max) and K(sub m) comparable to light-induced transport. These and other lines of evidence suggest that the transport of glutamate is facilitated by symport with Na(+), in an electrically neutral fashion, so that only the chemical component of the Na(+) gradient is a driving force.

  15. Low Z impurity transport in tokamaks. [Neoclassical transport theory

    Energy Technology Data Exchange (ETDEWEB)

    Hawryluk, R.J.; Suckewer, S.; Hirshman, S.P.

    1978-10-01

    Low Z impurity transport in tokamaks was simulated with a one-dimensional impurity transport model including both neoclassical and anomalous transport. The neoclassical fluxes are due to collisions between the background plasma and impurity ions as well as collisions between the various ionization states. The evaluation of the neoclassical fluxes takes into account the different collisionality regimes of the background plasma and the impurity ions. A limiter scrapeoff model is used to define the boundary conditions for the impurity ions in the plasma periphery. In order to account for the spectroscopic measurements of power radiated by the lower ionization states, fluxes due to anomalous transport are included. The sensitivity of the results to uncertainties in rate coefficients and plasma parameters in the periphery are investigated. The implications of the transport model for spectroscopic evaluation of impurity concentrations, impurity fluxes, and radiated power from line emission measurements are discussed.

    2016-02-01

    Full Text Available In the world and in our country, most of urban transportation is performed by public transportation. Public transportation is a system which provides transportation easiness and opportunity to people, not to vehicles. Therefore, giving priority to public transportation system is necessary in organizing urban transportation. In this study, in order to reduce traffic intensity and to facilitate passenger transportation in Izmit urban transportation, It is tried to determine appropriate public transportation system. For this, firstly, alternatives which could be used for public transportation were determined. These alternatives are metro, metrobus, tram, light rail system and monorail. Afterwards, the variables affecting decision making about public transportation were determined. These variables are cost, transportation line features, vehicle characteristics, sensitivity to environment and customer satisfaction. Lastly, most appropriate public transportation system is proposed by using the axiomatic design method. As a result, light trail system and metrobus are determined as the most appropriate alternatives for Izmit public transportation system.Keywords: Urban transportation, Multi criteria decision making, Axiomatic design

    The presynaptic, high-affinity choline transporter is a critical determinant of signalling by the neurotransmitter acetylcholine at both central and peripheral cholinergic synapses, including the neuromuscular junction. Here we describe an autosomal recessive presynaptic congenital myasthenic syndrome presenting with a broad clinical phenotype due to homozygous choline transporter missense mutations. The clinical phenotype ranges from the classical presentation of a congenital myasthenic syndrome in one patient (p.Pro210Leu), to severe neurodevelopmental delay with brain atrophy (p.Ser94Arg) and extend the clinical outcomes to a more severe spectrum with infantile lethality (p.Val112Glu). Cells transfected with mutant transporter construct revealed a virtually complete loss of transport activity that was paralleled by a reduction in transporter cell surface expression. Consistent with these findings, studies to determine the impact of gene mutations on the trafficking of the Caenorhabditis elegans choline transporter orthologue revealed deficits in transporter export to axons and nerve terminals. These findings contrast with our previous findings in autosomal dominant distal hereditary motor neuropathy of a dominant-negative frameshift mutation at the C-terminus of choline transporter that was associated with significantly reduced, but not completely abrogated choline transporter function. Together our findings define divergent neuropathological outcomes arising from different classes of choline transporter mutation with distinct disease processes and modes of inheritance. These findings underscore the essential role played by the choline transporter in sustaining acetylcholine neurotransmission at both central and neuromuscular synapses, with important implications for treatment and drug selection. © The Author (2017).

    Previous studies have determined that stress causes decreases in feed intake and efficiency in livestock, but the effect of repeated transport on these parameters has not been well studied. This study determined how repeated transport affected calf post-transport behavior, feed intake, ADG, and feed conversion. Thirty-six 4-mo-old Holstein steer calves were housed in groups of 6 with each group randomly assigned to either transport or control treatments. Each calf was assigned to an individual Calan gate feeder and feed intake was recorded daily. Transport calves were transported for 6 h in their groups in a 7.3 by 2.4 m gooseneck trailer divided into 3 compartments, at an average density of 0.87 m/calf, every 7 d for 5 consecutive weeks. After return to their home pens, behavior was recorded for transported calves at 5-min intervals for 1 h. Calf ADG and feed conversion were analyzed in a mixed model ANOVA, whereas feed intake was analyzed as a repeated measure in a mixed model ANOVA. Post-transport, calves followed a pattern of drinking, eating, and then lying down. The highest (82 ± 5% calves) and lowest (0 ± 5% calves) incidences of eating behavior occurred 10 and 60 min post-transport, respectively. Control calves had a higher feed intake than transported calves overall (7.29 ± 0.22 kg for control and 6.91 ± 0.21 kg for transport; = 0.01), for the feeding posttreatment (6.78 ± 0.27 kg for control and 6.01 ± 0.28 kg for transport; = 0.007), and the day after treatment (7.83 ± 0.23 kg for control and 7.08 ± 0.15 kg for transport; = 0.02). Feed intake for the feeding post-transport for transport calves significantly decreased after the second transport but increased with each successive transport ( < 0.0001). Overall, control calves had higher ADG than transported calves (1.34 ± 0.13 kg/d for control and 1.15 ± 0.12 kg/d for transport; = 0.006). No significant difference ( = 0.12) between treatments was detected for feed conversion. These results

  2. TRANSPORT OUTSOURCING AND TRANSPORT COLLABORATION RELATIONSHIP - THE RISK HEDGING PERSPECTIVE

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Although transport outsourcing decision-making and collaborative transport management (CTM have been “hot topics” for years, their links are still not thoroughly explored. The purpose of this paper is to contribute to a better understanding of the relationship between them. In particular, we focus on the conflicting and complementary features of these concepts with regard to their capability to hedge against transport outsourcing-related risks. Transport outsourcing is often a tool for transferring part of the demand risks from the primary parties in supply chains to transport service providers. However, new relationships introduce some new risks - outsourcing contract risks. It is important to identify, estimate and compare such kinds of risks. Transport collaboration may decrease both the demand risks and the outsourcing contract risks, although the relationship with the latter is more complex. It is used an exploratory research based on a combination of a literature review and empirical examples.

    2017-03-01

    Transport volume in the Slovak Republic is growing continuously every year. This rising trend is influenced by the development of car industry and its suppliers. Slovak republic has also a geographic strategy position in middle Europe from the side of transport corridors (east-west and north-south). The development of transport volume in freight transport depends on the transport and business processes between the European Union and China and it is an opportunity for Slovak republic to obtain transit transport flows. In the Slovak Republic, road transport has a dominant position in the transport market. The volume of road transport has gradually increased over the past years. The increase of road transport is reflected on the highways and speed roads in regions which have higher economic potential. The increase of rail transport as seen on the main rail corridors is not as significant as in road transport. Trade globalization also has an influence on the increase of transport volume in intermodal transport. Predicted increase in transport volume for this transport mode is from 2,3 mil ton per year at present to 8 mil ton in the year 2020. Selection of transport mode and carrier is an important aspect for logistic management, because companies (customers) want to reduce the number of carriers which they trade and they create the system of several key carriers. Bigger transport volume and more qualitative transport service give a possibility to reduce transport costs. This trend is positive for carriers too, because the carriers can focus only on the selected customers and provide more qualitative services. The paper is focused on the selection of transport mode based on the proposed methodology. The aims of the paper are, definition of criteria which directly influence the selection of transport modes, determination of criteria based on the subjectively methods, creation of process for the selection of transport modes and practical application of proposed

Studying the influence of legislative changes in the definition of the essence of concept of «minimum wage» and the wage system, used at the enterprise of postal service «Ukrposhta», has led to the conclusion that beginning from January 1, 2017 it is of the socially unjust and unfounded nature, because the principle of motivation of employees in respect of wages matching the quantity, quality, and results of labor, has been defied. It has been proposed to restructure the wage system at the enterprise of postal service «Ukrposhta» by optimizing the cross-categorial and cross-qualification relations, as well as the payment scheme.

  10. Probabilistic finite-size transport models for fusion: Anomalous transport and scaling laws

    International Nuclear Information System (INIS)

    Milligen, B.Ph. van; Sanchez, R.; Carreras, B.A.

    2004-01-01

    Transport in fusion plasmas in the low confinement mode is characterized by several remarkable properties: the anomalous scaling of transport with system size, stiff (or 'canonical') profiles, power degradation, and rapid transport phenomena. The present article explores the possibilities of constructing a unified transport model, based on the continuous-time random walk, in which all these phenomena are handled adequately. The resulting formalism appears to be sufficiently general to provide a sound starting point for the development of a full-blown plasma transport code, capable of incorporating the relevant microscopic transport mechanisms, and allowing predictions of confinement properties

    Transport is the sector with the highest final energy consumption and, without any significant policy changes, is forecast to remain so. In 2008, the IEA published 25 energy efficiency recommendations, among which four are for the transport sector. The recommendations focus on road transport and include policies on improving tyre energy efficiency, fuel economy standards for both light-duty vehicles and heavy-duty vehicles, and eco-driving. Implementation of the recommendations has been weaker in the transport sector than others. This paper updates the progress that has been made in implementing the transport energy efficiency recommendations in IEA countries since March 2009. Many countries have in the last year moved from 'planning to implement' to 'implementation underway', but none have fully implemented all transport energy efficiency recommendations. The IEA calls therefore for full and immediate implementation of the recommendations.

    Even though it may seem like something much more complex, maintenance is not more than the seed of continuity, the alchemy of eternal youth or the key to combating the cruel passage of time that haunts us all. Little does it matter where you are from or where you are going; it is irrelevant whether you are man, woman or machine. If you do not have a more or less sensible strategy of survival, reality can take you by surprise, without prior warning, at the wrong place and the wrong time. It is sad to see how what we thought was eternal, and thus do not care for and pamper as we should, eventually loses its qualities and functions over the years and fades away like a vague memory.

    1982-09-01

    This is a lecture on the present status of hypernuclear physics so that a gross picture can be obtained on what have been done and what should be done. The baryons with non-zero strangeness quantum number are generally called hyperons (hereafter denoted as Y), of which the lambda, sigma and xi particles together with the nucleon (N) constitute the baryon octet. A hypernucleus is the nuclear many-body system which contains hyperons in addition to nucleons as its constituent particles. The properties of the Y-N interaction can be extracted from the Y-N scattering data and information of hypernuclei along with theoretical consideration. The binding energy of a lambda particle in hypernuclei has been obtained from emulsion experiment. The hypernuclear excited states were observed in the (K - , pi - ) reaction experiment. The theoretical studies to understand the properties of the lambda single particle potential have been made within the framework of the G-matrix theory by employing Nijmegen OBE Y-N potential. The collective excitation of lambda hypernuclei is discussed. Spectroscopic information can be obtained by measuring the gamma-ray from hypernuclei. The sigma-hypernuclei have been observed through (K - , pi - ) reaction, while the experimental evidence of the xi-hypernuclei is not yet reported. The properties of both hypernuclei are discussed. The production and the properties of multi-hypernuclei are also discussed. The decay of lambda-hypernuclei will give structural characteristics of parents and daughters. Discussion of flavour nuclei and the concluding remarks are presented. (Kato, T.)

  5. Divide and conquer: processive transport enables multidrug transporters to tackle challenging drugs

    Directory of Open Access Journals (Sweden)

    Nir Fluman

    2014-09-01

    Full Text Available Multidrug transporters are membrane proteins that catalyze efflux of antibiotics and other toxic compounds from cells, thereby conferring drug resistance on various organisms. Unlike most solute transporters that transport a single type of compound or similar analogues, multidrug transporters are extremely promiscuous. They transport a broad spectrum of dissimilar drugs and represent a serious obstacle to antimicrobial or anticancer chemotherapy. Many challenging aspects of multidrug transporters, which are unique, have been studied in detail, including their ability to interact with chemically unrelated drugs, and how they utilize energy to drive efflux of compounds that are not only structurally but electrically different. A new and surprising dimension of the promiscuous nature of multidrug transporters has been described recently: they can move long molecules through the membrane in a processive manner.

    2017-06-01

    Monocarboxylate transporter 8 (MCT8) mediates thyroid hormone (TH) transport across the plasma membrane in many cell types. In order to better understand its mechanism, we have generated three new MCT8 homology models based on sugar transporters XylE in the intracellular opened (PDB ID: 4aj4) and the extracellular partly occluded (PDB ID: 4gby) conformations as well as FucP (PDB ID: 3o7q) and GLUT3 (PDB ID: 4zwc) in the fully extracellular opened conformation. T 3 -docking studies from both sides revealed interactions with His192, His415, Arg445 and Asp498 as previously identified. Selected mutations revealed further transport-sensitive positions mainly at the discontinuous transmembrane helices TMH7 and 10. Lys418 is potentially involved in neutralising the charge of the TH substrate because it can be replaced by charged, but not by uncharged, amino acids. The side chain of Thr503 was hypothesised to stabilise a helix break at TMH10 that undergoes a prominent local shift during the transport cycle. A T503V mutation accordingly affected transport. The aromatic Tyr419, the polar Ser313 and Ser314 as well as the charged Glu422 and Glu423 lining the transport channel have been studied. Based on related sugar transporters, we suggest an alternating access mechanism for MCT8 involving a series of amino acid positions previously and newly identified as critical for transport.

    Full Text Available Objective The death of animals during transport for slaughter is a major factor indicating the level of welfare in transported animals. The aim of this study was to assess mortality related to the commercial transport of finisher pigs for slaughter in the Czech Republic. Methods The inspectors of the State Veterinary Administration of the Czech Republic recorded the numbers of finisher pigs transported to processing plants in the Czech Republic for slaughter and the mortality in these pigs in relation to transport in the period from 2009 to 2014. Results Our results show that the likelihood of death losses in transported pigs increases with increasing transport distance. The transport-related mortality ranged from 0.049% in pigs transported for distances below 50 km to 0.145% in pigs transported for distances exceeding 300 km. The impact of external air temperature on the transport-related mortality found in our study clearly shows that current transport practices fail to ensure the welfare of pigs transported under other than moderate weather. Particularly cold temperatures below −2°C were associated with increased death losses in winter transport. Conclusion Despite a decreasing trend in the mortality of finisher pigs transported for slaughter in Europe, our study suggests that current transport conditions are not efficient at ensuring the welfare of pigs during transport for longer distances and the protection of pigs against the negative impact of extreme ambient temperatures. Further research should focus on developing practical guidelines to improve the welfare of pigs in transit accordingly.

    Transportation demands a large and increasing share of total energy consumption in Europe. At the same time many European countries are facing difficult decisions in achieving their long term environmental goals. Therefore energy policy, environmental policy and transport policy should be seen and discussed in a common perspective. In particular the relative contribution from the transport sector and the energy sector involves a number of important and difficult issues. The aim of the conference was to bring together economists, scientists, manufactures, energy planners, transport planners, and decision makers in order to discuss the importance of the transport sector in relation to energy demand and long term environmental goals. General conference sessions covered. Trends in Transport Energy Demand and Environmental constraints, Technological Development and New Transport Systems, Lifestyle Changes and the Transport Sector, Megacities: Solutions to the Transport and Air Pollution Problems, Effectiveness of Public Policies, Transport and Energy sector, and Methods, Models and Data.

Transporters are a large group of membrane-spanning proteins. They deliver essential nutrients, eject waste products, and assist the cell in sensing environmental conditions by forming a complex system of pumps and channels. Although studies have effectively characterized individual M. truncatula transporters in several databases, until now there has been no available systematic database that includes all transporters in M. truncatula. Description The M. truncatula transporter database (MTDB contains comprehensive information on the transporters in M. truncatula. Based on the TransportTP method, we have presented a novel prediction pipeline. A total of 3,665 putative transporters have been annotated based on International Medicago Genome Annotated Group (IMGAG V3.5 V3 and the M. truncatula Gene Index (MTGI V10.0 releases and assigned to 162 families according to the transporter classification system. These families were further classified into seven types according to their transport mode and energy coupling mechanism. Extensive annotations referring to each protein were generated, including basic protein function, expressed sequence tag (EST mapping, genome locus, three-dimensional template prediction, transmembrane segment, and domain annotation. A chromosome distribution map and text-based Basic Local Alignment Search Tools were also created. In addition, we have provided a way to explore the expression of putative M. truncatula transporter genes under stress treatments. Conclusions In summary, the MTDB enables the exploration and comparative analysis of putative transporters in M. truncatula. A user-friendly web interface and regular updates make MTDB valuable to researchers in related fields. The MTDB is freely available now to all users at http://bioinformatics.cau.edu.cn/MtTransporter/.

    Continuous ambulatory peritoneal dialysis (CAPD) patients with high peritoneal solute transport rate often have inadequate peritoneal fluid transport. It is not known whether this inadequate fluid transport is due solely to a too rapid fall of osmotic pressure, or if the decreased effectiveness of fluid transport is also a contributing factor. To analyze fluid transport parameters and the effectiveness of dialysis fluid osmotic pressure in the induction of fluid flow in CAPD patients with different small solute transport rates. 44 CAPD patients were placed in low (n = 6), low-average (n = 13), high-average (n = 19), and high (n = 6) transport groups according to a modified peritoneal equilibration test (PET). The study involved a 6-hour peritoneal dialysis dwell with 2 L 3.86% glucose dialysis fluid for each patient. Radioisotopically labeled serum albumin was added as a volume marker.The fluid transport parameters (osmotic conductance and fluid absorption rate) were estimated using three mathematical models of fluid transport: (1) Pyle model (model P), which describes ultrafiltration rate as an exponential function of time; (2) model OS, which is based on the linear relationship of ultrafiltration rate and overall osmolality gradient between dialysis fluid and blood; and (3) model G, which is based on the linear relationship between ultrafiltration rate and glucose concentration gradient between dialysis fluid and blood. Diffusive mass transport coefficients (K(BD)) for glucose, urea, creatinine, potassium, and sodium were estimated using the modified Babb-Randerson-Farrell model. The high transport group had significantly lower dialysate volume and glucose and osmolality gradients between dialysate and blood, but significantly higher K(BD) for small solutes compared with the other transport groups. Osmotic conductance, fluid absorption rate, and initial ultrafiltration rate did not differ among the transport groups for model OS and model P. Model G yielded

    An evaluation was performed to assess whether the reliability of a transportable storage cask system and the risks associated with its use are comparable to those associated with existing transport cask systems and, if they are not, determine how the transportable storage cask system can be made as reliable as existing systems. Reliability and failure mode analyses of both transport-only casks and transportable storage casks and implementation options are compared. Current knowledge regarding the potential effects of a long-term dry storage environment on spent fuel and cask materials is reviewed. A summary assessment of the consideration for deploying a transportable storage cask (TSC) system with emphasis on preliminary design, validation and operational recommendations for TSC implementations is presented. The analyses conclude that a transportable storage cask can likely be shipped upopened by applying a combination of design considerations and operational constraints, including environmental monitoring and pretransport assessments of functional reliability of the cask. A proper mix of these constraints should yield risk parity with any existing transport cask

  18. Australian Experience in Implementing Transport Safety Regulations and Transport Security Recommendations

    International Nuclear Information System (INIS)

    Sarkar, S.

    2016-01-01

    Australian transport safety and security regulatory framework is governed by Commonwealth, State and Territory legislations. There are eleven competent authorities in Australia that includes three Commonwealth authorities, six states and two territory authorities. IAEA Regulations for Safe Transport of Radioactive Material (TS-R-1, 2005 edition) is applied through Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) Code of Practice for Transport of Radioactive Material 2008 by road, rail and waterways not covered by marine legislations. All states and territories apply this Transport Code through their regulatory system. For air transport, the Civil Aviation Act 1988 adopts the requirements of the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air DOC 9284, which also adopts TS-R-1. The security of radioactive material in air transport is achieved via the Aviation Transport Security Act 2004. For sea transport Australian Marine Order 41 applies the requirements of IMDG (International Maritime Dangerous Goods) Code which also adopts TS-R-1. The security of radioactive material (nuclear material) is governed by two Commonwealth Agencies namely, ARPANSA and ASNO (Australian Safeguards and Non-proliferation Office) . ARPANSA regulates the security of radioactive sources through ARPANSA Code of Practice for the Security of Radioactive Sources 2007 which is based on the IAEA Draft Security Series. ASNO regulates security of nuclear material including U, Th and Pu through the Nuclear Non-Proliferation (Safeguards) Act, and the object of which is to give effect to certain obligations that Australia has as a party to the NPT, Australia’s safeguards agreement with the IAEA, and other bilateral safeguards agreements and certain obligations that Australia has as a party to the Convention for the Physical Protection of Nuclear Materials (CPPNM). This paper presents the effectiveness of regulatory approaches for safe and secure

  19. The serotonin transporter: Examination of the changes in transporter affinity induced by ligand binding

    International Nuclear Information System (INIS)

    Humphreys, C.J.

    1989-01-01

    The plasmalemmal serotonin transporter uses transmembrane gradients of Na + , Cl - and K + to accumulate serotonin within blood platelets. Transport is competitively inhibited by the antidepressant imipramine. Like serotonin transport, imipramine binding requires Na + . Unlike serotonin, however, imipramine does not appear to be transported. To gain insight into the mechanism of serotonin transport the author have analyzed the influences of Na + and Cl - , the two ions cotransported with serotonin, on both serotonin transport and the interaction of imipramine and other antidepressant drugs with the plasmalemmal serotonin transporter of human platelets. Additionally, the author have synthesized, purified and characterized the binding of 2-iodoimipramine to the serotonin transporter. Finally, the author have conducted a preliminary study of the inhibition of serotonin transport and imipramine binding produced by dicyclohexylcarbodiimide. My results reveal many instances of positive heterotropic cooperativity in ligand binding to the serotonin transporter. Na + binding enhances the transporters affinity for imipramine and several other antidepressant drugs, and also increases the affinity for Cl - . Cl - enhances the transporters affinity for imipramine, as well as for Na + . At concentrations in the range of its K M for transport serotonin is a competitive inhibitor of imipramine binding. At much higher concentrations, however, serotonin also inhibits imipramines dissociation rate constant. This latter effect which is Na + -independent and species specific, is apparently produced by serotonin binding at a second, low affinity site on, or near, the transporter complex. Iodoimipramine competitively inhibit both [ 3 H]imipramine binding and [ 3 H]serotonin transport

    2003-01-01

    Health impact assessment (HIA) can be used to examine the relationships between inequalities and health. This HIA of Edinburgh's transport policy demonstrates how HIA can examine how different transport policies can affect different population groupings to varying degrees. In this case, Edinburgh's economy is based on tourism, financial services and Government bodies. These need a good transport infrastructure, which maintains a vibrant city centre. A transport policy that promotes walking, cycling and public transport supports this and is also good for health. The HIA suggested that greater spend on public transport and supporting sustainable modes of transport was beneficial to health, and offered scope to reduce inequalities. This message was understood by the City Council and influenced the development of the city's transport and land-use strategies. The paper discusses how HIA can influence public policy.

    Materials that undergo metal-insulator transitions (MITs) are under intense study, because the transition is scientifically fascinating and technologically promising for various applications. Among these materials, VO 2 has served as a prototype due to its favorable transition temperature. While the physical underpinnings of the transition have been heavily investigated experimentally and computationally, quantitative modeling of electronic transport in the two phases has yet to be undertaken. In this work, we establish a density-functional-theory (DFT)-based approach with Hubbard U correction (DFT + U) to model electronic transport properties in VO 2 in the semiconducting and metallic regimes, focusing on band transport using the Boltzmann transport equations. We synthesized high quality VO 2 films and measured the transport quantities across the transition, in order to calibrate the free parameters in the model. We find that the experimental calibration of the Hubbard correction term can efficiently and adequately model the metallic and semiconducting phases, allowing for further computational design of MIT materials for desirable transport properties

    Full Text Available Development of mixed transportation is a prospective direction of development of the transportation system of Ukraine. The article analyses the modern state of development of mixed transportation of freight in Ukraine. The most popular types of combined transportation (refers to multi-modal are container and contrailer trains, which are formed both in Ukraine (Viking and Yaroslav and in other countries, first of all, Belarus (Zubr. One of the reasons of underdevelopment of mixed transportation of freight in Ukraine is absence of a developed network of transportation and logistic centres. The article offers to form a network of transportation and logistic centres in Ukraine as a way of intensification of development of mixed transportations of freight, since they facilitate co-ordination of use of various types of transport and support integrated management of material flows. Transportation and logistic centres should become a start-up complex, around which transportation and logistic clusters would be gradually formed. Transportation and logistic clusters is a new efficient form of network organisation and management of transportation and logistic services and they also ensure growth of efficiency of use of the regional transportation and logistic potential of Ukraine. The article shows prospective supporting transportation and logistic centres and centres of formation of transportation and logistic clusters in the territory of Ukraine. Formation of efficient transportation and logistic system of Ukraine on the basis of a network of transportation and logistic clusters would facilitate entering of Ukraine into the world transportation environment and would allow acceleration of introduction of efficient logistic schemes of freight delivery, in particular, mixed transportation of freight.

  10. Transport on prescription: How can GPs contribute to the promotion of active transport?

    2017-10-01

    Active transport (ie walking, cycling, using public transport) can play a part in reducing non-communicable diseases (NCDs). Very little is known about how general practitioners (GPs) can contribute to promoting active transport. We explored GPs' ideas around active transport, and potential barriers and facilitators to its promotion in the clinical setting. Using a maximal variation sample, we conducted 10 semi-structured interviews with GPs in Victoria, Australia. The socioecological model informed data collection and analysis. The idea of active transport resonated with GPs. Limited awareness around active transport and safety concerns regarding commuter cycling were barriers to clinical promotion. GPs believed patients' health, cultural norms, socioeconomic position and access to supportive environments could facilitate participation. Future efforts should prioritise awareness of active transport among GPs. The perspectives of GPs would be valuable to policymakers, particularly in designing programs to mitigate inequalities around active transport access and use.

    This Transportation System Requirements Document (Trans-SRD) describes the functions to be performed by and the technical requirements for the Transportation System to transport spent nuclear fuel (SNF) and high-level radioactive waste (HLW) from Purchaser and Producer sites to a Civilian Radioactive Waste Management System (CRWMS) site, and between CRWMS sites. The purpose of this document is to define the system-level requirements for Transportation consistent with the CRWMS Requirement Document (CRD). These requirements include design and operations requirements to the extent they impact on the development of the physical segments of Transportation. The document also presents an overall description of Transportation, its functions, its segments, and the requirements allocated to the segments and the system-level interfaces with Transportation.

    2004-01-01

    Full Text Available The focus of the article is conditioning settlement to public transport on the regional and urban level. Similar to occurrences in Western Europe even in Slovenia strong settlement pressures and issues tied to development of suburbanisation are emerging in wider hinterlands of larger cities. In regional centres, where strong transport flows with frequent congestion happen, public transport should be the backbone of the transport system. It is important for consolidation of larger gravitation areas, especially conurbations. We can nevertheless establish that parallel to increasing use of private cars, the use of public transport is decreasing. Thus the present condition demands improvements of transport systems and suitable settlement density in conjunction with development of public transport. This can be achieved only by synergetic linking of public transport development and physical planning in a sustainable settlement system. In the Ljubljana functional region we specifically dealt with links between settlement and the regional public transport system, above all the proposed regional light-railway and tram system in the strict urban area. The decentralised denser settlement model is presented. Based on the study concerning settlement development in the railway corridors we proposed potential possibilities for denser settlement in the immediate areas of suburban railway stations in the northern part of the region, from Črnuče to Kamnik.

  13. Human transporter database: comprehensive knowledge and discovery tools in the human transporter genes.

    Full Text Available Transporters are essential in homeostatic exchange of endogenous and exogenous substances at the systematic, organic, cellular, and subcellular levels. Gene mutations of transporters are often related to pharmacogenetics traits. Recent developments in high throughput technologies on genomics, transcriptomics and proteomics allow in depth studies of transporter genes in normal cellular processes and diverse disease conditions. The flood of high throughput data have resulted in urgent need for an updated knowledgebase with curated, organized, and annotated human transporters in an easily accessible way. Using a pipeline with the combination of automated keywords query, sequence similarity search and manual curation on transporters, we collected 1,555 human non-redundant transporter genes to develop the Human Transporter Database (HTD (http://htd.cbi.pku.edu.cn. Based on the extensive annotations, global properties of the transporter genes were illustrated, such as expression patterns and polymorphisms in relationships with their ligands. We noted that the human transporters were enriched in many fundamental biological processes such as oxidative phosphorylation and cardiac muscle contraction, and significantly associated with Mendelian and complex diseases such as epilepsy and sudden infant death syndrome. Overall, HTD provides a well-organized interface to facilitate research communities to search detailed molecular and genetic information of transporters for development of personalized medicine.

    In Japan, the transport of nuclear fuel materials strictly meets the above international convention and domestic regulations as well. Information on the transport of nuclear fuel materials within the country and between the country and foreign countries is treated carefully. Nuclear fuel materials are categorized for transport and are physically protected accordingly. Certain transportation information is treated with special precautions, including prior arrangements among sender, recipient and carrier, and prior agreement between entities subject to the jurisdiction and regulation of supplier and recipient countries. In the case of international transport, this information includes specifying time, place and procedures for transferring transport and responsibility. (O.M.)

    2004-01-01

    The purpose of this model report is to document the drift scale radionuclide transport model, taking into account the effects of emplacement drifts on flow and transport in the vicinity of the drift, which are not captured in the mountain-scale unsaturated zone (UZ) flow and transport models ''UZ Flow Models and Submodels'' (BSC 2004 [DIRS 169861]), ''Radionuclide Transport Models Under Ambient Conditions'' (BSC 2004 [DIRS 164500]), and ''Particle Tracking Model and Abstraction of Transport Process'' (BSC 2004 [DIRS 170041]). The drift scale radionuclide transport model is intended to be used as an alternative model for comparison with the engineered barrier system (EBS) radionuclide transport model ''EBS Radionuclide Transport Abstraction'' (BSC 2004 [DIRS 169868]). For that purpose, two alternative models have been developed for drift-scale radionuclide transport. One of the alternative models is a dual continuum flow and transport model called the drift shadow model. The effects of variations in the flow field and fracture-matrix interaction in the vicinity of a waste emplacement drift are investigated through sensitivity studies using the drift shadow model (Houseworth et al. 2003 [DIRS 164394]). In this model, the flow is significantly perturbed (reduced) beneath the waste emplacement drifts. However, comparisons of transport in this perturbed flow field with transport in an unperturbed flow field show similar results if the transport is initiated in the rock matrix. This has led to a second alternative model, called the fracture-matrix partitioning model, that focuses on the partitioning of radionuclide transport between the fractures and matrix upon exiting the waste emplacement drift. The fracture-matrix partitioning model computes the partitioning, between fractures and matrix, of diffusive radionuclide transport from the invert (for drifts without seepage) into the rock water. The invert is the structure constructed in a drift to provide the floor of the

    2005-01-01

    This paper will report on the recent progress in transport modelling of Internal Transport Barrier (ITB) plasmas. Two separate issues will be covered, fully predictive transport modelling of ITBs in the multi-tokamak database, including micro-stability analyses of ITBs, and predictive closed-loop (i.e. real-time control) transport simulations of the q-profile and ITBs. For the first time, the predictive capabilities of the mixed Bohm/GyroBohm and Weiland transport models are investigated with discharges from the ITPA ITB database by fully predictive transport simulations. The predictive transport simulations with the Bohm/GyroBohm model agree very well with experimental results from JET and JT-60U. In order to achieve a good agreement in DIII-D, the stabilisation had to be included into the model, showing the significant role played by the stabilisation in governing the physics of the ITBs. The significant role of the stabilisation is also emphasised by the gyrokinetic analysis. The Weiland transport model shows only limited agreement between the model predictions and experimental results with respect to the formation and location of the ITB. The fully predictive closed-loop simulations with real-time control of the q-profile and ITB show that it is possible to reach various set-point profiles for q and ITB and control them for longer than a current diffusion time in JET using the same real-time control technique as in the experiments.

    The Third Aerospace Symposium in Braunschweig presented, for the first time, the possibility of bringing together the classical disciplines of aerospace engineering and the natural science disciplines of meteorology and air chemistry in a european setting. In this way, aspects of environmental impact on the atmosphere could be examined quantitatively. An essential finding of the european conference, is the unrestricted agreement of the experts that the given launch frequencies of the present orbital transport result in a negligible amount of pollutants being released in the atmosphere. The symposium does, however, call attention to the increasing need to consider the effect of orbital and atmospheric environmental impact of a future increase in launch frequencies of orbital transport in connection with future space stations. The Third Aerospace Symposium, 'Orbital Transport, Technical, Meteorological and Chemical Aspects', constituted a first forum of discussion for engineers and scientists. Questions of new orbital transport technologies and their environmental impact were to be discussed towards a first consensus. Through the 34 reports and articles, the general problems of space transportation and environmental protection were addressed, as well as particular aspects of high temperatures during reentry in the atmosphere of the earth, precision navigation of flight vehicles or flow behavior and air chemistry in the stratosphere.

    I. The handling and transport of radioactive wastes involves the danger of irradiation and contamination. It is indispensable: - to lay down a special set of rules governing the removal and transport of wastes within centres or from one centre to another; - to give charge of this transportation to a group containing teams of specialists. The organisation, equipment and output of these teams is being examined. II. Certain materials are particularly dangerous to transport, and for these special vehicles and fixed installations are necessary. This is the case especially for the evacuation of very active liquids. A transport vehicle is described, consisting of a trailer tractor and a recipient holding 500 litres of liquid of which the activity can reach 1000 C/l; the decanting operation, the route to be followed by the vehicle, and the precautions taken are also described.

    This issue of the 'Sustainable Transportation Monitor', published by the Centre for Sustainable Transportation located in Mississauga, Ontario, reports on key findings from a project involving children and transportation in the Halton and Peel regions of Ontario, recently completed by the Centre. Excerpts from the report summarized in this issue include data on children's travel in Halton and Peel, and a discussion on possible contribution of transport practices to the growing incidence of obesity among Canadian children. Results of the study indicate that until about age 18, travel by children on schooldays is dominated by the journey to and from school. School bus is the choice of 28 per cent, and passenger car by 23 per cent among 11-to-14- year-olds; the share of travel by car is larger for older young people and also likely larger among 6-to-10-year-olds. Physical inactivity has been highlighted as the contributing factor to excess body weight and obesity in this, and other studies. Data collected for this study corroborates the findings of other studies by showing a positive correlation between obesity and transport energy use in 18 affluent countries, suggesting that a high level of use of motorized transport contributes to inactivity and body weight gain. Several alternate means of transportation, with the potential to combat obesity, are proposed. 46 refs.

    Full Text Available Summary: Vesicular glutamate transporters (VGLUTs fill synaptic vesicles with glutamate and are thus essential for glutamatergic neurotransmission. However, VGLUTs were originally discovered as members of a transporter subfamily specific for inorganic phosphate (Pi. It is still unclear how VGLUTs accommodate glutamate transport coupled to an electrochemical proton gradient ΔμH+ with inversely directed Pi transport coupled to the Na+ gradient and the membrane potential. Using both functional reconstitution and heterologous expression, we show that VGLUT transports glutamate and Pi using a single substrate binding site but different coupling to cation gradients. When facing the cytoplasm, both ions are transported into synaptic vesicles in a ΔμH+-dependent fashion, with glutamate preferred over Pi. When facing the extracellular space, Pi is transported in a Na+-coupled manner, with glutamate competing for binding but at lower affinity. We conclude that VGLUTs have dual functions in both vesicle transmitter loading and Pi homeostasis within glutamatergic neurons. : Preobraschenski et al. show that the vesicular glutamate transporter functions as a bi-directional phosphate transporter that is coupled with different cations in each direction and hence may play a key role in neuronal phosphate homeostasis.

    The purpose of this Design Analysis is to develop preliminary design of the waste package transporter used for waste package (WP) transport and related functions in the subsurface repository. This analysis refines the conceptual design that was started in Phase I of the Viability Assessment. This analysis supports the development of a reliable emplacement concept and a retrieval concept for license application design. The scope of this analysis includes the following activities: (1) Assess features of the transporter design and evaluate alternative design solutions for mechanical components. (2) Develop mechanical equipment details for the transporter. (3) Prepare a preliminary structural evaluation for the transporter. (4) Identify and recommend the equipment design for waste package transport and related functions. (5) Investigate transport equipment interface tolerances. This analysis supports the development of the waste package transporter for the transport, emplacement, and retrieval of packaged radioactive waste forms in the subsurface repository. Once the waste containers are closed and accepted, the packaged radioactive waste forms are termed waste packages (WP). This terminology was finalized as this analysis neared completion; therefore, the term disposal container is used in several references (i.e., the System Description Document (SDD)) (Ref. 5.6). In this analysis and the applicable reference documents, the term ''disposal container'' is synonymous with ''waste package''

    In this review article, we discuss key features of the transport phenomena and theoretical modelling to understand them. Experimental observations have revealed the nature of anomalous transport, i.e., the enhancement of the transport coefficients by the gradients of the plasma profiles, the pinch phenomena, the radial profile of the anomalous transport coefficients, the variation of the transport among the Bohm diffusion, Pseudo-classical confinement, L-mode and variety of improved confinement modes, and the sudden jumps such as L-H transition. Starting from the formalism of the transport matrix, the modelling based on the low frequency instabilities are reviewed. Theoretical results in the range of drift wave frequency are examined. Problems in theories based on the quasilinear and mixing-length estimates lead to the renewal of the turbulence theory, and the physics picture of the self-sustained turbulence is discussed. The theory of transport using the fluid equation of plasma is developed, showing that the new approach is very promising in explaining abovementioned characteristics of anomalous transport in both L-mode and improved confinement plasmas. The interference of the fluxes is the key to construct the physics basis of the bifurcation theory for the L-H transition. The present status of theories on the mechanisms of improved confinement is discussed. Modelling on the nonlocal nature of transport is briefly discussed. Finally, the impact of the anomalous transport on disruptive phenomena is also described. (author) 95 refs

    Substrate transport across a membrane accomplished by a secondary active transporter (SAT) is essential to the normal physiological function of living cells. In the present research, a series of all-atom molecular dynamics (MD) simulations under different electric field (EF) strengths was performed to investigate the effect of an external EF on the substrate transport of an SAT. The results show that EF both affects the interaction between substrate and related protein's residues by changing their conformations and tunes the timeline of the transport event, which collectively reduces the height of energy barrier for substrate transport and results in the appearance of two intermediate conformations under the existence of an external EF. Our work spotlights the crucial influence of external EFs on the substrate transport of SATs and could provide a more penetrating understanding of the substrate transport mechanism of SATs.

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in ''Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration'' (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment for the license application (TSPA-LA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA-LA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data.

    The safe, environmentally sound and publicly acceptable disposal of high level wastes and spent fuels is becoming a very important issue. The operational safety assessment of a repository including a transportation safety assessment is a fundamental part in order to achieve this goal. According to the long term management strategy for spent fuels in Korea, they will be transported from the spent fuel pools in each nuclear power plant to the central interim storage facility (CISF) which is to start operation in 2016. Therefore, we have to determine the safe and economical logistics for the transportation of these spent fuels by considering their transportation risks and costs. In this study, we developed four transportation scenarios by considering the type of transportation casks and transport means in order to suggest safe and economical transportation logistics for spent fuels. Also, we estimated and compared the transportation risks resulting from the accidents during the transportation of spent fuels for these four transportation scenarios

    According to the long term management strategy for spent fuels in Korea, they will be transported from the spent fuel pools in each nuclear power plant to the central interim storage facility (CISF) which is to start operation in 2016. At the start of the operation of the final repository (FR), by the year 2065, transport will then take place between the CISF and the FR. Therefore, we have to determine the safe and economical logistics for the transportation of these spent fuels by considering their transportation risks and costs. In this study, we developed four transportation scenarios for a maritime transportation by considering the type of transportation casks and transport means in order to suggest safe and economical transportation logistics for the spent fuels in Korea. And, we estimated and compared the transportation risks for these four transportation scenarios. Also, we estimated and compared the transportation risks resulting from accidents during the transportation of PWR and PHWR spent fuels by road trailers from the CISF and the FR. From the results of this study, we found that risks resulting from accidents during the transportation of the spent fuels have a very low radiological risk activity with a manageable safety and health consequences. The results of this study can be used as basic data for the development of safe and economical logistics for a transportation of the spent fuels in Korea by considering the transportation costs for the four scenarios which will be needed in the near future.

    Scrape-off-layer (SOL) convection in fusion experiments appears to be a universal phenomenon that can 'short-circuit' the divertor in some cases. The theory of 'blob' transport provides a simple and robust physical paradigm for studying convective transport. This paper summarizes recent advances in the theory of blob transport and its comparison with 2D and 3D computer simulations. We also discuss the common physical basis relating radial transport of blobs, pellets, and ELMs and a new blob regime that may lead to a connection between blob transport and the density limit.

    A general discussion of the physics of contributon transport is presented. To facilitate this discussion, a Boltzmann-like transport equation for contributons is obtained, and special contributon cross sections are defined. However, the main goal of this study is to identify contributon transport equations and investigate possible deterministic solution techniques. Four approaches to the deterministic solution of the contributon transport problem are investigated. These approaches are an attempt to exploit certain attractive properties of the contributon flux, psi = phi phi + , where phi and phi + are the solutions to the forward and adjoint Boltzmann transport equations

    Presently the amount of radioisotopes increased very much and the application spread to wide fields in Japan. Since facilities using radioisotopes are distributed to every place in the country, every transport means such as airplanes, automobiles, railways, ships and mail are employed. The problems in the transport of radioisotopes include too much difference in the recognition of criticality among the persons concerning the transportation and treatment, knowledges of shielding and energy difference in the types of radiation and handling of sealed and unsealed sources and the casks for transport. IAEA established the latest regulation on the package of radioisotopes in 1973, and in Japan, the related regulations will be revised according to the IAEA's regulation in near future. The present status in the inspection at the time of shipment, supervision, and the measures to the accidents are described for the transport means of airplanes, ships and automobiles. Finally, concerning the insurance for cargo, the objects of the insurance for radioisotopes include either the radioisotopes contained in casks for transportation or radioisotopes only. Generally, radioisotopes are accepted in all-risk condition including casks and limited to the useful radioisotopes for peaceful use. (Wakatsuki, Y

The organized transport of essential biological materials throughout the neuron is required to support its growth, function, and viability. In this review, we focus on insights that have emerged from the genetic analysis of long-distance axonal transport between the cell body and the synaptic terminal. We also discuss recent genetic evidence that supports the hypothesis that disruptions in axonal transport may cause or dramatically contribute to neurodegenerative diseases.

    Impurity behaviour in JET internal transport barrier (ITB) discharges with reversed shear has been investigated. Metallic impurities accumulate in cases with too strong peaking of the main ion density profile. The accumulation is due to inwardly directed drift velocities inside the ITB radius. The strength of the impurity peaking increases with the impurity charge and is low for the low-Z elements C and Ne. Transport calculations show that the observed behaviour is consistent with dominant neoclassical impurity transport inside the ITB. In some cases, MHD events in the core flatten the radial profile of the metallic impurity. (author)

    Full Text Available La distinction entre l’urbain et le rural était claire sous l’Ancien Régime, dans des sociétés peu mobiles. La révolution industrielle accentue l’identification entre la ville, l’industrie et la modernité. Après la Seconde Guerre mondiale, le développement du transport routier affranchit l’industrie des localisations urbaines et la périurbanisation progresse. En même temps, l’accroissement des productivités agricoles libère de plus en plus de main-d’œuvre paysanne. Après deux siècles au moins d’exode rural, les campagnes se rurbanisent, mais cette rurbanisation s’inscrit dans un contexte global de mégapolisation. Cette configuration devrait imposer une nouvelle appréciation des rapports entre l’urbain et le rural, en ce compris leurs rapports politiques.The distinction between urban and rural was clear under the Ancien Régime, as societies featured a low level of mobility. The industrial revolution increased the identification between cities, manufacturing and modernity. After the Second World War, growing road traffic freed industries from urban locations and suburbanisation thus increased. Simultaneously, the increase in food productivity required fewer and fewer agricultural workers. After more than two centuries of rural exodus, rurbanisation transformed rural areas, even as this very process of rurbanisation should be seen as part of a global megapolization process. This pattern implies new kinds of relations between the rural and the urban, including from a political point of view.

In planning the unloading equipment at the site, due consideration should be given to the fact that at a later time this equipment should also be suitable for the transport of heavy components and spent fuel assemblies.

    Regional scale transport models are needed to support the long-term evaluation of groundwater quality and to develop management strategies aiming to prevent serious groundwater degradation. The purpose of this study is to evaluate the capacity of previously-developed upscaling approaches to accurately describe main solute transport processes including the capture of late-time tails under changing boundary conditions. Advective-dispersive contaminant transport in a 3D heterogeneous domain was simulated and used as a reference solution. Equivalent transport under homogeneous flow conditions were then evaluated applying the Multi-Rate Mass Transfer (MRMT) model. The random walk particle tracking method was used for both heterogeneous and homogeneous-MRMT scenarios under steady state and transient conditions. The results indicate that the MRMT model can capture the tails satisfactorily for plume transported with ambient steady-state flow field. However, when boundary conditions change, the mass transfer model calibrated for transport under steady-state conditions cannot accurately reproduce the tailing effect observed for the heterogeneous scenario. The deteriorating impact of transient boundary conditions on the upscaled model is more significant for regions where flow fields are dramatically affected, highlighting the poor applicability of the MRMT approach for complex field settings. Accurately simulating mass in both mobile and immobile zones is critical to represent the transport process under transient flow conditions and will be the future focus of our study.

  7. Canadian hydrocarbon transportation system : transportation assessment

    International Nuclear Information System (INIS)

    2006-06-01

    This document provided an assessment of the Canadian hydrocarbon transportation system. In addition to regulating the construction and operation of Canada's 45,000 km of pipeline that cross international and provincial borders, Canada's National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. The ability of pipelines to delivery this energy is critical to the country's economic prosperity. The pipeline system includes large-diameter, cross-country, high-pressure natural gas pipelines, low-pressure crude oil and oil products pipelines and small-diameter pipelines. In order to assess the hydrocarbon transportation system, staff at the NEB collected data from pipeline companies and a range of publicly available sources. The Board also held discussions with members of the investment community regarding capital markets and emerging issues. The assessment focused largely on evaluating whether Canadians benefit from an efficient energy infrastructure and markets. The safety and environmental integrity of the pipeline system was also evaluated. The current adequacy of pipeline capacity was assessed based on price differentials compared with firm service tolls for major transportation paths; capacity utilization on pipelines; and, the degree of apportionment on major oil pipelines. The NEB concluded that the Canadian hydrocarbon transportation system is working effectively, with an adequate capacity in place on existing natural gas pipelines, but with a tight capacity on oil pipelines. It was noted that shippers continue to indicate that they are reasonably satisfied with the services provided by pipeline companies and that the NEB-regulated pipeline companies are financially stable. 14 refs, 11 tabs., 28 figs., 4 appendices

    2002-01-01

    In JET plasmas with internal transport barrier (ITB) the behaviour of metallic and low-Z impurities (C, Ne) was investigated. In ITB discharges with reversed shear, the metallic impurities accumulate in cases with too strong peaking of the density profile, while the concentration of low-Z elements C and Ne is only mildly peaked. The accumulation might be so strong, that the central radiation approximately equals the central heating power followed by a radiative collapse of the transport barrier. The radial location with strong impurity gradients (convective barrier) was identified to be situated inside (not at!) the heat flux barrier. Calculations of neo-classical transport were performed for these discharges, including impurity-impurity collisions. It was found, that the observed Z-dependence of the impurity peaking and the location of the impurity 'barrier' can be explained with neo-classical transport. ITB discharges with monotonic shear show less inward convection and seem to be advantageous with respect to plasma purity. (author)

    Although transport of nuclear substances represents only a very small part of the global transport of dangerous goods, it takes place every day all over the world and it is part of our daily life. Transport of nuclear material takes also place at every stage of the nuclear fuel cycle; radioactive materials are carried out all over the world by all major modes of transport: sea, air, road and rail. Despite the large number of nuclear transports, they are not considered as posing a serious risk. A major nuclear incident is almost always associated with the operating of fixed installations such as nuclear power plants; just think about Three Mile Island and Chernobyl. This perception is strengthened by the absence so far of serious accidents in the nuclear transport sector and this finding is in fact proof of the very safe conditions of nuclear transport. But accidents can never be excluded entirely and in some cases damages could be as large as those caused by fixed installations. This means that protection of the interests of possible victims should also be covered in a correct way. That is why the special nuclear liability regime has also been developed to cover damage caused by a nuclear transport accident. As stated by Patrick Reyners, the prime motivation for originally adopting a special nuclear regime was the harmonisation of national legislation and that nowhere more than in the field of international transport operations is such harmonisation felt desirable . The international legal regime has been developed along two tracks, one based on the mode of transport and the other based on the notion of dangerous goods. The linkage between those two tracks is of permanent concern and the mode of transport is the key element to determine which international instrument should be applicable. The purpose of this paper is to briefly introduce the financial security provided by the insurance industry to cover the international nuclear liability regime for nuclear

    There is a recently well-documented association between childhood epilepsy and earlysymptomaticsyndromeselicitingneurodevelopmentalclinicalexaminations (ESSENCE) including autism spectrum disorder, but the relationship between febrile seizures and ESSENCE is less clear. The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing population-based study targeting twins born in Sweden since July 1, 1992. Parents of 27,092 twins were interviewed using a validated DSM-IV-based interview for ESSENCE, in connection with the twins' ninth or twelfth birthday. Diagnoses of febrile seizures (n = 492) and epilepsy (n = 282) were based on data from the Swedish National Patient Register. Prevalence of ESSENCE in individuals with febrile seizures and epilepsy was compared with prevalence in the twin population without seizures. The association between febrile seizures and ESSENCE was considered before and after adjustment for epilepsy. Age of diagnosis of febrile seizures and epilepsy was considered as a possible correlate of ESSENCE in febrile seizures and epilepsy. The rate of ESSENCE in febrile seizures and epilepsy was significantly higher than in the total population without seizures (all P epilepsy, a significant association between febrile seizures and autism spectrum disorder, developmental coordination disorder, and intellectual disability remained. Earlier age of onset was associated with all ESSENCE except attention-deficit/hyperactivity disorder in epilepsy but not with ESSENCE in febrile seizures. In a nationally representative sample of twins, there was an increased rate of ESSENCE in childhood epilepsy and in febrile seizures. Febrile seizures alone could occur as a marker for a broader ESSENCE phenotype. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Stochastic models of intracellular transport

    KAUST Repository

    Bressloff, Paul C.

    2013-01-09

    The interior of a living cell is a crowded, heterogenuous, fluctuating environment. Hence, a major challenge in modeling intracellular transport is to analyze stochastic processes within complex environments. Broadly speaking, there are two basic mechanisms for intracellular transport: passive diffusion and motor-driven active transport. Diffusive transport can be formulated in terms of the motion of an overdamped Brownian particle. On the other hand, active transport requires chemical energy, usually in the form of adenosine triphosphate hydrolysis, and can be direction specific, allowing biomolecules to be transported long distances; this is particularly important in neurons due to their complex geometry. In this review a wide range of analytical methods and models of intracellular transport is presented. In the case of diffusive transport, narrow escape problems, diffusion to a small target, confined and single-file diffusion, homogenization theory, and fractional diffusion are considered. In the case of active transport, Brownian ratchets, random walk models, exclusion processes, random intermittent search processes, quasi-steady-state reduction methods, and mean-field approximations are considered. Applications include receptor trafficking, axonal transport, membrane diffusion, nuclear transport, protein-DNA interactions, virus trafficking, and the self-organization of subcellular structures. © 2013 American Physical Society.

    2004-01-01

    A discomforting reality has materialized on the transportation scene: our existing air and ground infrastructures will not scale to meet our nation's 21st century demands and expectations for mobility, commerce, safety, and security. The consequence of inaction is diminished quality of life and economic opportunity in the 21st century. Clearly, new thinking is required for transportation that can scale to meet to the realities of a networked, knowledge-based economy in which the value of time is a new coin of the realm. This paper proposes a framework, or topology, for thinking about the problem of scalability of the system of networks that comprise the aviation system. This framework highlights the role of integrated communication-navigation-surveillance systems in enabling scalability of future air transportation networks. Scalability, in this vein, is a goal of the recently formed Joint Planning and Development Office for the Next Generation Air Transportation System. New foundations for 21st thinking about air transportation are underpinned by several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems. Complexity science and modern network theory give rise to one of the technological developments of importance. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of scalability, efficiency, robustness, resilience, and other metrics. The paper offers an air transportation system topology as framework for transportation system innovation. Successful outcomes of innovation in air transportation could lay the foundations for new paradigms for aircraft and their operating capabilities, air transportation system architectures, and airspace architectures and procedural concepts. The topology proposed considers air transportation as a system of networks, within which

    2014-12-01

    Full Text Available Sustainability is a term used more often lately, based on three factors: social, economic, and environmental. Sustainable transport systems increase social cohesion, reduce environmental problems and help create a more efficient economy. Sustainable transport consists in a complex system that is designed to ensure mobility needs of present generations without damaging the environment and health factors. By improving energy and material consumption, it must be capable to satisfy in optimum conditions the need for mobility for future generations. The current transportation system has not a character of sustainability.

  11. Estimates of Lagrangian particle transport by wave groups: forward transport by Stokes drift and backward transport by the return flow

    Science.gov (United States)

    van den Bremer, Ton S.; Taylor, Paul H.

    2014-11-01

    Although the literature has examined Stokes drift, the net Lagrangian transport by particles due to of surface gravity waves, in great detail, the motion of fluid particles transported by surface gravity wave groups has received considerably less attention. In practice nevertheless, the wave field on the open sea often has a group-like structure. The motion of particles is different, as particles at sufficient depth are transported backwards by the Eulerian return current that was first described by Longuet-Higgins & Stewart (1962) and forms an inseparable counterpart of Stokes drift for wave groups ensuring the (irrotational) mass balance holds. We use WKB theory to study the variation of the Lagrangian transport by the return current with depth distinguishing two-dimensional seas, three-dimensional seas, infinite depth and finite depth. We then provide dimensional estimates of the net horizontal Lagrangian transport by the Stokes drift on the one hand and the return flow on the other hand for realistic sea states in all four cases. Finally we propose a simple scaling relationship for the transition depth: the depth above which Lagrangian particles are transported forwards by the Stokes drift and below which such particles are transported backwards by the return current.

    Since the control of transport of radioactive materials was given to A.S.N. 10 years ago, A.S.N. has strengthened the radioactive material transport inspections, in particular of the designers, manufacturers, carriers and consignors. A.S.N. has implemented INES scale for incidents during transport. It has participated as much as possible to IAEA working groups in order to improve the international regulatory framework. And, supported by I.R.S.N., A.S.N. has performed a periodic safety review of existing package models and has approved new models incorporating innovative design features. Finally, A.S.N. has tested its emergency responses to procedures to an accident involving the transport of radioactive materials. All these actions taken together have led to improvement in and reinforcement of the safety culture among the transport operators; this has been acknowledged by a recent audit T.R.A.N.S.A.S. performed by IAEA. In spite of all these actions, there are not approved by the competent authority. As A.S.N. is in charge of every field in radioprotection, this should help to intensify the control. In addition, the different kinds of transport are also tackled as rail transport with S.N.C.F. radiological risk training, air transport through nuclear medicine. Some experience feedback are given such radioactive waste transport to the storage facilities in the Aube or how to protect the population after a nuclear transport incident with the O.R.S.E.C.-T.M.S. plans.

  15. Transportation energy in global cities: Sustainable transportation comes in from the cold?

    2001-01-01

    The energy, environmental and social benefits of sustainable transportation, i.e, public transit, biking and walking, have long been recognized but are now mainstream in global and local transportation policy debates. However, the economic value of sustainable transportation has always been seen as secondary, unless many external costs were included. The results of a new global study show that cities with significant sustainable transportation systems have reduced costs on road construction and maintenance; better operating cost recovery and fuel-efficiency; fewer road accidents and less air pollution. In overall terms, the percentage of city funds going to transportation is reduced. The data show that cities with the most roads have the highest transportation costs and the most rail-oriented cities have the lowest. Further, the most sprawling cities have the highest direct and indirect costs for transportation. Thus, strategies to contain sprawl, to reurbanize, to build new rail systems info car-dependent suburbs with focussed sub-centers, and to facilitate biking and walking, not only will improve energy efficiency but will reduce costs to the economy of a city. Strategies that build freeways and add to sprawl will do the opposite. Trends indicate that moves toward sustainable urban patterns are beginning. The need to operationalize sustainable transportation strategies in planning and engineering practice and in the politics of infrastructure funding remains a major challenge. Some cities are showing how this can be done. (author)

    This article investigates various ways that transportation policy and planning decisions affect public health and better ways to incorporate public health objectives into transport planning. Conventional planning tends to consider some public health impacts, such as crash risk and pollution emissions measured per vehicle-kilometer, but generally ignores health problems resulting from less active transport (reduced walking and cycling activity) and the additional crashes and pollution caused by increased vehicle mileage. As a result, transport agencies tend to undervalue strategies that increase transport system diversity and reduce vehicle travel. This article identifies various win-win strategies that can help improve public health and other planning objectives.

  17. Rapid transporter regulation prevents substrate flow traffic jams in boron transport

    Science.gov (United States)

    Sotta, Naoyuki; Duncan, Susan; Tanaka, Mayuki; Sato, Takafumi

    2017-01-01

    Nutrient uptake by roots often involves substrate-dependent regulated nutrient transporters. For robust uptake, the system requires a regulatory circuit within cells and a collective, coordinated behaviour across the tissue. A paradigm for such systems is boron uptake, known for its directional transport and homeostasis, as boron is essential for plant growth but toxic at high concentrations. In Arabidopsis thaliana, boron uptake occurs via diffusion facilitators (NIPs) and exporters (BORs), each presenting distinct polarity. Intriguingly, although boron soil concentrations are homogenous and stable, both transporters manifest strikingly swift boron-dependent regulation. Through mathematical modelling, we demonstrate that slower regulation of these transporters leads to physiologically detrimental oscillatory behaviour. Cells become periodically exposed to potentially cytotoxic boron levels, and nutrient throughput to the xylem becomes hampered. We conclude that, while maintaining homeostasis, swift transporter regulation within a polarised tissue context is critical to prevent intrinsic traffic-jam like behaviour of nutrient flow.

It is necessary to draw up special regulations governing the removal and transport of waste within the centres or from one centre to another, and to entrust transport to a group in charge of specialized teams. The organization, equipment and efficiency of such teams is then considered. II. Certain types of transport operation are particularly dangerous and require special transport units and fixed installations. This applies, in particular, to the disposal of highly radioactive liquids.

  19. Understanding transporter specificity and the discrete appearance of channel-like gating domains in transporters

    Directory of Open Access Journals (Sweden)

    GEORGE eDIALLINAS

    2014-09-01

    Full Text Available Transporters are ubiquitous proteins mediating the translocation of solutes across cell membranes, a biological process involved in nutrition, signaling, neurotransmission, cell communication and drug uptake or efflux. Similarly to enzymes, most transporters have a single substrate binding-site and thus their activity follows Michaelis-Menten kinetics. Substrate binding elicits a series of structural changes, which produce a transporter conformer open towards the side opposite to the one from where the substrate was originally bound. This mechanism, involving alternate outward- and inward-facing transporter conformers, has gained significant support from structural, genetic, biochemical and biophysical approaches. Most transporters are specific for a given substrate or a group of substrates with similar chemical structure, but substrate specificity and/or affinity can vary dramatically, even among members of a transporter family that show high overall amino acid sequence and structural similarity. The current view is that transporter substrate affinity or specificity is determined by a small number of interactions a given solute can make within a specific binding site. However, genetic, biochemical and in silico modeling studies with the purine transporter UapA of the filamentous ascomycete Aspergillus nidulans have challenged this dogma. This review highlights results leading to a novel concept, stating that substrate specificity, but also transport kinetics and transporter turnover, are determined by subtle intramolecular interactions between a major substrate binding site and independent outward- or cytoplasmically-facing gating domains, analogous to those present in channels. This concept is supported by recent structural evidence from several, phylogenetically and functionally distinct transporter families. The significance of this concept is discussed in relationship to the role and potential exploitation of transporters in drug action.

The transport mechanism of catalposide was investigated in HEK293 and LLC-PK1 cells overexpressing the relevant transporters. The uptake of catalposide was 319-, 13.6-, and 9.3-fold greater in HEK293 cells overexpressing OAT3, OATP1B1, and OATP1B3 transporters, respectively, than in HEK293 control cells. The increased uptake of catalposide via the OAT3, OATP1B1, and OATP1B3 transporters was decreased to basal levels in the presence of representative inhibitors such as probenecid, furosemide, and cimetidine (for OAT3 and cyclosporin A, gemfibrozil, and rifampin (for OATP1B1 and OATP1B3. The concentration-dependent OAT3-mediated uptake of catalposide revealed the following kinetic parameters: Michaelis constant (Km =41.5 µM, maximum uptake rate (Vmax =46.2 pmol/minute, and intrinsic clearance (CLint =1.11 µL/minute. OATP1B1- and OATP1B3-mediated catalposide uptake also showed concentration dependency, with low CLint values of 0.035 and 0.034 µL/minute, respectively. However, the OCT1, OCT2, OAT1, P-gp, and BCRP transporters were apparently not involved in the uptake of catalposide into cells. In addition, catalposide inhibited the transport activities of OAT3, OATP1B1, and OATP1B3 with half-maximal inhibitory concentration values of 83, 200, and 235 µ

    Radiation exposures of members of critical groups of the general population and of transport personnel resulting from normal transport of radioactive wastes to the planned final waste repository Konrad have been evaluated in detail. By applying probabilistic safety assessment techniques radiological risks from transport accidents have been analysed by quantifying potential radiation exposures and contaminations of the biosphere in connection with their expected frequencies of occurrence. The Konrad transport study concentrates on the local region of the waste repository, where all transports converge. (orig.) [de

    Full Text Available The aim is here to evaluate the difference between the energy and exergy (or available energy balances when heat recovery is considered in an internal combustion engine. In the first case, the entropy of the system is not taken into account so that, the maximum useful work recoverable from a system can not be estimated. Then, the second case is much more adapted to estimate heat recovery potential. In this paper, two modern engines are evaluated. First, an up-to-date gasoline engine: three-cylinder, downsized, low friction, then a modern common rail downsized Diesel engine. For each one, two energy and exergy balances are given for two different part-load operating points representative of the NEDC cycle using experimental data from steady state engine test benches. For the Diesel engine, it is shown that effective work represents around 30% and that around 55% of the energy introduced into the combustion chamber is lost (in the form of heat, especially in exhaust gas, in water coolant and oil. But when considering exergy balance, only 12% of the total exergy introduced through the fuel can be recovered, in order to produce useful work. Expecting a 25% exergy recovery efficiency, the effective engine efficiency could be increased by 10%. For the gasoline engine, the increase of the output work could be around 15%. L’objectif est ici d’évaluer la différence entre bilan d’énergie et d’exergie (ou énergie utile pour des moteurs à combustion interne lorsque la problématique de récupération d’énergie est prise en compte. Dans le premier cas, l’entropie du système n’est pas considérée, si bien que le travail utile maximal qu’il est possible de récupérer d’un système ne peut pas être estimé. Tandis que le second cas est bien mieux adapté pour estimer le potentiel de la récupération d’énergie. Dans cet article, deux moteurs modernes sont étudiés. Le premier est un moteur essence récent, 3 cylindres, de cylindr

    Coupled phenomena (thermal and chemical osmosis, hyperfiltration, coupled diffusion, thermal diffusion, thermal filtration, Dufour effect) may play an important role in fluid, solute and heat transport in clay-rich formations, such as the Opalinus Clay (OPA), which are being considered as potential hosts for radioactive waste repositories. In this study, the potential effects of coupled phenomena on radionuclide transport in the vicinity of a repository for vitrified high-level radioactive waste (HLW) and spent nuclear fuel (SF) hosted by the Opalinus Clay, at times equal to or greater than the expected lifetime of the waste canisters (about 1000 years), have been addressed. Firstly, estimates of the solute fluxes associated with chemical osmosis, hyperfiltration, thermal diffusion and thermal osmosis have been calculated. Available experimental data concerning coupled transport phenomena in compacted clays, and the hydrogeological and geochemical conditions to which the Opalinus Clay is subject, have been used for these estimates. These estimates suggest that thermal osmosis is the only coupled transport mechanism that could have a strong impact on solute and fluid transport in the vicinity of the repository. Secondly, estimates of the heat fluxes associated with thermal filtration and the Dufour effect in the vicinity of the repository have been calculated. The calculated heat fluxes are absolutely negligible compared to the heat flux caused by thermal conduction. As a further step to obtain additional insight into the effects of coupled phenomena on solute transport, the solute fluxes associated with advection, chemical diffusion, thermal and chemical osmosis, hyperfiltration and thermal diffusion have been incorporated into a simple one-dimensional transport equation. The analytical solution of this equation, with appropriate parameters, shows again that thermal osmosis is the only coupled transport mechanism that could have a strong effect on repository

    Materials that undergo metal-insulator transitions (MITs) are under intense study, because the transition is scientifically fascinating and technologically promising for various applications. Among these materials, VO{sub 2} has served as a prototype due to its favorable transition temperature. While the physical underpinnings of the transition have been heavily investigated experimentally and computationally, quantitative modeling of electronic transport in the two phases has yet to be undertaken. In this work, we establish a density-functional-theory (DFT)-based approach with Hubbard U correction (DFT + U) to model electronic transport properties in VO{sub 2} in the semiconducting and metallic regimes, focusing on band transport using the Boltzmann transport equations. We synthesized high quality VO{sub 2} films and measured the transport quantities across the transition, in order to calibrate the free parameters in the model. We find that the experimental calibration of the Hubbard correction term can efficiently and adequately model the metallic and semiconducting phases, allowing for further computational design of MIT materials for desirable transport properties.

    Early crystal structures of prokaryotic CLC proteins identified three Cl– binding sites: internal (Sint), central (Scen), and external (Sext). A conserved external GLU (GLUex) residue acts as a gate competing for Sext. Recently, the first crystal structure of a eukaryotic transporter, CmCLC, revealed that in this transporter GLUex competes instead for Scen. Here, we use molecular dynamics simulations to investigate Cl– transport through CmCLC. The gating and Cl–/H+ transport cycle are inferre...

  11. A transport synthetic acceleration method for transport iterations

    Ramone, G.L.; Adams, M.L.

    1997-01-01

    A family of transport synthetic acceleration (TSA) methods for iteratively solving within group scattering problems is presented. A single iteration in these schemes consists of a transport sweep followed by a low-order calculation, which itself is a simplified transport problem. The method for isotropic-scattering problems in X-Y geometry is described. The Fourier analysis of a model problem for equations with no spatial discretization shows that a previously proposed TSA method is unstable in two dimensions but that the modifications make it stable and rapidly convergent. The same procedure for discretized transport equations, using the step characteristic and two bilinear discontinuous methods, shows that discretization enhances TSA performance. A conjugate gradient algorithm for the low-order problem is described, a crude quadrature set for the low-order problem is proposed, and the number of low-order iterations per high-order sweep is limited to a relatively small value. These features lead to simple and efficient improvements to the method. TSA is tested on a series of problems, and a set of parameters is proposed for which the method behaves especially well. TSA achieves a substantial reduction in computational cost over source iteration, regardless of discretization parameters or material properties, and this reduction increases with the difficulty of the problem

    Full Text Available Aim: The changes of the hypothalamic pituitary adrenal (HPA axis response to a long distance transportation results in increase of adrenocorticotropic hormone (ACTH and cortisol levels. The purpose of the study was to quantify the level of short-term road transport stress on circulating ACTH and cortisol concentrations, related to the effect of previous handling and transport experience of horses. Materials and Methods: The study was performed on 56 healthy horses after short-term road transport of 30 km. The horses were divided into four groups, Groups A, B, C, and D, with respect to the handling quality: Good (Groups A and B, bad (Group D, and minimal handling (Group C conditions. According to the previous transport, experience horses were divided as follows: Horses of Groups A and D had been experienced long-distance transportation before; horses of Groups B and C had been limited experience of transportation. Results: One-way RM-ANOVA showed significant effects of transport on ACTH changes in Groups B and C and on cortisol changes in both Groups A and B. Groups A and B showed lower baseline ACTH and cortisol values than Groups C and D; Groups A and B showed lower post-transport ACTH values than Groups C and D. Groups A, B, and C showed lower post-transport cortisol values than Group D. Only Groups A and B horses have shown an adequate capacity of stress response to transportation. Conclusion: The previous transport experience and quality of handling could influence the HPA axis physiological responses of horses after short-term road transport.

    Evans, T.E.; Finkenthal, D.F.

    1998-04-01

    A description of the carbon transport and sputtering physics contained in the Monte Carlo Impurity (MCI) transport code is given. Examples of statistically significant carbon transport pathways are examined using MCI's unique tracking visualizer and a mechanism for enhanced carbon accumulation on the high field side of the divertor chamber is discussed. Comparisons between carbon emissions calculated with MCI and those measured in the DIII-D tokamak are described. Good qualitative agreement is found between 2D carbon emission patterns calculated with MCI and experimentally measured carbon patterns. While uncertainties in the sputtering physics, atomic data, and transport models have made quantitative comparisons with experiments more difficult, recent results using a physics based model for physical and chemical sputtering has yielded simulations with about 50% of the total carbon radiation measured in the divertor. These results and plans for future improvement in the physics models and atomic data are discussed

    The performance of urban transport depends on a variety of factors related to metropolitan structure; in particular, the patterns of commuting, roads and public transport (PT) systems. To evaluate urban transport planning efforts, there is a need for a metric expressing the aggregate performance of the city's transport systems which should relate to residents' preferences. The existing metrics have typically focused on a measure to express the proximity of job locations to residences. A Transport Performance Index (TPI) is proposed in which the total cost of transportation system (operational and environmental costs) is divided by willingness to pay (WTP) for transport plus the willingness to accept (WTA) the environmental effects on residents. Transport operational as well as the environmental costs are derived from a simulation of all transport systems, to particular designs of spatial development. Willingness to pay for transport and willingness to accept the environmental effects are derived from surveys among residents. Simulations were modelled of Surabaya's spatial structure and public transport expansion. The results indicate that the current TPI is high, which will double by 2030. With a hypothetical polycentric city structure and adjusted job housing balance, a lower index occurs because of the improvements in urban transport performance. A low index means that the residents obtain much benefit from the alternative proposed. This illustrates the importance of residents' preferences in urban spatial planning in order to achieve efficient urban transport. Applying the index suggests that city authorities should provide fair and equitable public transport systems for suburban residents in the effort to control the phenomenon of urban sprawl. This index is certainly a good tool and prospective benchmark for measuring sustainability in relation to urban development.

    Full Text Available Analyzing the level of Polish transport safety culture can be seen that it is now dependent on the culture of safety management within the organization and the requirements and recommendations of law in this field for different modes of transport (air, rail, road, water. Of the four basic types of transport requirements are widely developed in the aviation, rail, and water – the sea. In order to harmonize the requirements for transport safety so it appears advisable to develop a platform for exchange of safety information for different modes of transport, and the development of good practices multimodal offering the possibility of improving Polish transport safety. Described in the publication of the proposal in addition to the alignment platform experience and knowledge in the field of transport safety in all its kinds, it can also be a tool for perfecting new operators of public transport.

  20. Over-expressed maltose transporters in laboratory and lager yeasts: localization and competition with endogenous transporters.

    Vidgren, Virve; Londesborough, John

    2018-05-31

    Plain and fluorescently tagged versions of Agt1, Mtt1 and Malx1 maltose transporters were over-expressed in two laboratory yeasts and one lager yeast. The plain and tagged versions of each transporter supported similar transport activities, indicating that they are similarly trafficked and have similar catalytic activities. When they were expressed under the control of the strong constitutive PGK1 promoter only minor proportions of the fluorescent transporters were associated with the plasma membrane, the rest being found in intracellular structures. Transport activity of each tagged transporter in each host was roughly proportional to the plasma membrane-associated fluorescence. All three transporters were subject to glucose-triggered inactivation when the medium glucose concentration was abruptly raised. Results also suggest competition between endogenous and over-expressed transporters for access to the plasma membrane. This article is protected by copyright. All rights reserved.

  5. Carbon dioxide emissions from passenger transport in China since 1949: Implications for developing sustainable transport

    International Nuclear Information System (INIS)

    Loo, Becky P.Y.; Li, Linna

    2012-01-01

    This paper traces the historical evolution and spatial disparity of CO 2 emissions from passenger transport in China. The general trends of CO 2 emissions from four passenger transport modes are estimated by both the distance-based and fuel-based methods. The results suggest that CO 2 emissions from road transport represented the leading source of passenger transport CO 2 emissions in China. Moreover, they have continued to grow rapidly. Air transport was the second largest contributor since 1998. Emissions from rail and water transport have remained relatively stable with lower emission intensity. At the provincial level, great regional disparity was noticeable, especially in road transport. Moreover, the decomposition analysis shows that income growth was the principal factor leading to the growth of passenger transport CO 2 emissions in China for both the 1949–1979 and 1980–2009 periods. The second most important factor was increased transport intensity and modal shifts for the former and the latter period, respectively. The main factor contributed to emission reduction was the lower emission intensity supported by policies, although the effect was weak. In the future, more policies to encourage modal shifts toward sustainable transport modes and travel reduction should be encouraged. - Highlights: ► CO 2 emissions from passenger transport in China were estimated. ► Road transport was the largest contributor to CO 2 emission. Air transport followed. ► Factors influencing CO 2 emissions growth are analyzed by decomposition analysis. ► Income growth, higher travel intensity and modal shift were driving CO 2 emissions up. ► Policies to promote modal shifts and travel demand reduction should be encouraged.

    The hopping process, which differs substantially from conventional transport processes in crystals, is the central process in the transport phenomena discussed in this book. Throughout the book the term ``hopping'' is defined as the inelastic tunneling transfer of an electron between two localized electronic states centered at different locations. Such processes do not occur in conventional electronic transport in solids, since localized states are not compatible with the translational symmetry of crystals.The rapid growth of interest in hopping transport has followed in the footsteps of the

  11. Sustainable urban transport indicators: tool for evaluating transport sustainability in the mega cities of Pakistan

    International Nuclear Information System (INIS)

    Imran, M.

    2005-01-01

    Urban Transport is an important sector to accomplish the goal of sustainable development in Pakistan. This is important because of the high growth of the transport sector's energy consumption, road crashes and greenhouse gas emissions. This becomes significant in the Pakistani cities where motor vehicle fleet is growing at two to three times the rate of population. Transport Policies has resulted high growth of urban road traffic, increasing air and noise pollution throughout the country. This situation raised the question how to achieve sustainable urban transport in the mega cities of Pakistan? Development of sustainable urban transport indicators will provide an opportunity to analyze current transport policies to assess Pakistan progress towards or away from sustainability. Medium Term Development Framework (2005-10) has selected to analyze against establish sustainable urban transport indicators for Pakistan. On the basis of analysis, it has found that MWF has tried to address transport problem in a piecemeal manner, rather than adopting a holistic approach. Implementing MTDF policies on transport is not fully matched with a long term commitment to achieving sustainable development in Pakistan. (author)

  12. Neurosteroid Transport in the Brain: Role of ABC and SLC Transporters

    Directory of Open Access Journals (Sweden)

    Markus Grube

    2018-04-01

    Full Text Available Neurosteroids, comprising pregnane, androstane, and sulfated steroids can alter neuronal excitability through interaction with ligand-gated ion channels and other receptors and have therefore a therapeutic potential in several brain disorders. They can be formed in brain cells or are synthesized by an endocrine gland and reach the brain by penetrating the blood–brain barrier (BBB. Especially sulfated steroids such as pregnenolone sulfate (PregS and dehydroepiandrosterone sulfate (DHEAS depend on transporter proteins to cross membranes. In this review, we discuss the involvement of ATP-binding cassette (ABC- and solute carrier (SLC-type membrane proteins in the transport of these compounds at the BBB and in the choroid plexus (CP, but also in the secretion from neurons and glial cells. Among the ABC transporters, especially BCRP (ABCG2 and several MRP/ABCC subfamily members (MRP1, MRP4, MRP8 are expressed in the brain and known to efflux conjugated steroids. Furthermore, several SLC transporters have been shown to mediate cellular uptake of steroid sulfates. These include members of the OATP/SLCO subfamily, namely OATP1A2 and OATP2B1, as well as OAT3 (SLC22A3, which have been reported to be expressed at the BBB, in the CP and in part in neurons. Furthermore, a role of the organic solute transporter OSTα-OSTβ (SLC51A/B in brain DHEAS/PregS homeostasis has been proposed. This transporter was reported to be localized especially in steroidogenic cells of the cerebellum and hippocampus. To date, the impact of transporters on neurosteroid homeostasis is still poorly understood. Further insights are desirable also with regard to the therapeutic potential of these compounds.

    Information on the emissions and energy consumption of different vehicles per transported amount of goods has up to last years been minimal. The unit emissions mean the amount of harmful compounds in the flue gases of a vehicle per service, time or energy unit. National three-year MOBILE 2-research program, started in 1999, determines the unit emissions of all the traffic sectors in Finland. VTT Building and Transport mainly carry out the research, but the Institute of Transportation Engineering of the Tampere University of Technology (TTKK) is responsible for a part of the research. The objective of the project is to create common rules for the determination of unit emissions values, and to determine the best possible values for Finnish conditions. Unit emission data is mainly needed for evaluation of the environmental impacts of production plants and other activities containing transportation of commodities. At the web sites of VTT Building and Transport there are about 60 pages of text and tables (about 4000 values) on unit emissions. The URL of the pages is http://www.vtt.fi/rte/projects/lipastoe/index.htm. These web pages present data on all the transportation sectors (road, railroad, water and air transportation), most of the materials concerning road transportation. Following compounds and values are included: CO, HC, NO x , particulates, SO 2 , CO 2 and energy consumption. Methane and nitrous oxide emissions values have also been presented

    Experiments on the transport barrier in Helical plasmas are reviewed. There are two mechanisms of transport improvement, that results in the formation of the transport barrier. One is the improvement of neoclassical transport by reducing the ripple loss with radial electric field, which exist only in helical plasma. The other is the improvement of anomalous transport due to the suppression of fluctuations associated with a radial electric field shear both in tokamak and helical plasma. The formation of the transport barrier can be triggered by the radial electric field shear associated with the transition of the radial electric field (L/H transition or ion-electron root transition) or the peaked density or the optimization of magnetic field shear. The mechanisms of transport barrier formation are also discussed. (author). 60 refs

    2013-01-01

    Transport is one of the most challenge sectors when addressing energy security and climate change due to its high reliance on oil products and lack of the alternative fuels. This paper explores the ability of three transport strategies to contribute to the development of a sustainable transport in China. With this purpose in mind, a Chinese transport model has been created and three current transport strategies which are high speed railway (HSR), urban rail transit (URT) and electric vehicle (EV) were evaluated together with a reference transport system in 2020. As conservative results, 13% of the energy saving and 12% of the CO 2 emission reduction can be attained by accomplishing three strategies compared with the reference transport system. However, the energy demand of transport in 2020 with the implementation of three strategies will be about 1.7 times as much as today. The three strategies show the potential of drawing the transport demand to the more energy efficient vehicles; however, more initiatives are needed if the sustainable transport is the long term objective, such as the solutions to stabilise the private vehicle demands, to continuously improve the vehicle efficiency and to boost the alternative fuels produced from the renewable energy sources. - Highlights: • A Chinese transport model was created and three transport strategies were evaluated • Transport is the biggest driver of the oil demand in China not the industry • The energy demand of transport in 2020 will be twice as much as today • Strategies contribute 13% energy saving and 12% CO 2 emission reduction • More initiatives are needed if a sustainable transport is the long-term objective

    2007-01-01

    The heavy transportation in Brazil is generally done by highways. The radioactive material transportation follow this same rule. Whenever a radioactive material is carried by the road, by the sea or by the air, in some cases, a kind of combination of those transportation ways, the transport manager has to create a Transportation Plan and submit it to CNEN. Only after CNEN's approval, the transportation can be done. The plan must have the main action on Radiation Protection, giving responsibilities and showing all the directing that will be take. Although, the Brazilian's highways are not in good conditions, one could say that some of them are not good enough for any kind of transportation. But we are facing radioactive material use increase but the hospitals and industries, that the reason it's much more common that kind of transportation nowadays. So, because of that, a special attention by the governments must be provide to those activities. This paper goal is to show the real conditions of some important highways in Brazil in a radioactive protection's perspective and give some suggestions to adjust some of those roads to this new reality.

  3. An approach to improving transporting velocity in the long-range ultrasonic transportation of micro-particles

    2014-01-01

    In existing ultrasonic transportation methods, the long-range transportation of micro-particles is always realized in step-by-step way. Due to the substantial decrease of the driving force in each step, the transportation is lower-speed and stair-stepping. To improve the transporting velocity, a non-stepping ultrasonic transportation approach is proposed. By quantitatively analyzing the acoustic potential well, an optimal region is defined as the position, where the largest driving force is provided under the condition that the driving force is simultaneously the major component of an acoustic radiation force. To keep the micro-particle trapped in the optimal region during the whole transportation process, an approach of optimizing the phase-shifting velocity and phase-shifting step is adopted. Due to the stable and large driving force, the displacement of the micro-particle is an approximately linear function of time, instead of a stair-stepping function of time as in the existing step-by-step methods. An experimental setup is also developed to validate this approach. Long-range ultrasonic transportations of zirconium beads with high transporting velocity were realized. The experimental results demonstrated that this approach is an effective way to improve transporting velocity in the long-range ultrasonic transportation of micro-particles

    Modelling of moisture transport in wood is of great importance as most mechanical and physical properties of wood depend on moisture content. Moisture transport in porous materials is often described by Ficks second law, but several observations indicate that this does not apply very well to wood....... Recently at the Technical University of Denmark, Department of Civil Engineering, a new model for moisture transport in wood has been developed. The model divides the transport into two phases, namely water vapour in the cell lumens and bound water in the cell walls....

  6. Nuclear transport - The regulatory dimension

    International Nuclear Information System (INIS)

    Green, L.

    2002-01-01

    The benefits that the peaceful applications of nuclear energy have brought to society are due in no small part to industry's capacity to transport radioactive materials safely, efficiently and reliably. The nuclear transport industry has a vital role in realising a fundamental objective of the International Atomic Energy Agency (IAEA) as stated in its statute to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world. The context in which transports currently take place is complex, and rapidly changing. In many respects transport is being viewed as an integral market issue and not a subsidiary concern. The availability of carriers drives routing decisions and changes in material flows necessitate new approaches to packaging and transport scenarios. Pressures on the transport sector are not without serious consequences; they can cause delays and in some cases cancellation of planned movements. Complex routings and the necessary use of chartered carriers can push up costs and work against cost efficiency. Since the events of 11 September 2001 the security of nuclear transports has contributed an added dimension to how transports take place. Transports of radioactive material have an outstanding safety record, indeed the transport of such materials could be regarded as a model for the transport of other classes of dangerous goods. This safety record is achieved by two inter-related factors. It is due primarily to well founded regulations developed by such key intergovernmental organisations as the IAEA, with the essential contributions of the member states who participate in the implementation of regulations and the review process. It is due also to the professionalism of those in the industry. There is a necessary synergy between the two - between the regulators whose task it is to make and to enforce the rules for safe, efficient and reliable transport and those whose job it is to transport within the rules.

    1997-01-01

    This document is the fourth Transportation Statistics Annual Report (TSAR) prepared by the Bureau of Transportation Statistics (BTS) for the President and Congress. As in previous years, it reports on the state of U.S. transportation system at two levels. First, in Part I, it provides a statistical and interpretive survey of the system—its physical characteristics, its economic attributes, aspects of its use and performance, and the scale and severity of unintended consequences of transportation, such as fatalities and injuries, oil import dependency, and environment impacts. Part I also explores the state of transportation statistics, and new needs of the rapidly changing world of transportation. Second, Part II of the report, as in prior years, explores in detail the performance of the U.S. transportation system from the perspective of desired social outcomes or strategic goals. This year, the performance aspect of transportation chosen for thematic treatment is “Mobility and Access,” which complements past TSAR theme sections on “The Economic Performance of Transportation” (1995) and “Transportation and the Environment” (1996). Mobility and access are at the heart of the transportation system’s performance from the user’s perspective. In what ways and to what extent does the geographic freedom provided by transportation enhance personal fulfillment of the nation’s residents and contribute to economic advancement of people and businesses? This broad question underlies many of the topics examined in Part II: What is the current level of personal mobility in the United States, and how does it vary by sex, age, income level, urban or rural location, and over time? What factors explain variations? Has transportation helped improve people’s access to work, shopping, recreational facilities, and medical services, and in what ways and in what locations? How have barriers, such as age, disabilities, or lack of an automobile, affected these

    The transport device for nuclear fuel powder, which does not disintegrate during transport, has a transport pipe which starts with its entry end from the floor or a closed container and opens with its outlet end at the top into a closed separation container connect via a powder filter to a suction pump. By alternate regular opening and closing of a first control valve for transport gas fitted to a transport pipe to a supply duct and a second control valve for transport gas fitted to the container to an additional supply duct, alternating plugs of nuclear fuel powder and transport gas cushions are formed and are transported to the outlet end of the transport pipe.

    Attributes of the built environment can influence active transportation, including use of public transportation. However, the relationship between perceptions of the built environment and use of public transportation deserves further attention. The objectives of this study were 1) to assess the relationship between personal characteristics and public transportation use with meeting national recommendations for moderate physical activity through walking for transportation and 2) to examine associations between personal and perceived environmental factors and frequency of public transportation use. In 2012, we administered a mail-based survey to 772 adults in St Louis, Missouri, to assess perceptions of the built environment, physical activity, and transportation behaviors. The abbreviated International Physical Activity Questionnaire was used to assess walking for transportation and use of public transportation. The Neighborhood Environment Walkability Scale was used to examine perceptions of the built environment. Associations were assessed by using multinomial logistic regression. People who used public transportation at least once in the previous week were more likely to meet moderate physical activity recommendations by walking for transportation. Age and employment were significantly associated with public transportation use. Perceptions of high traffic speed and high crime were negatively associated with public transportation use. Our results were consistent with previous research suggesting that public transportation use is related to walking for transportation. More importantly, our study suggests that perceptions of traffic speed and crime are related to frequency of public transportation use. Future interventions to encourage public transportation use should consider policy and planning decisions that reduce traffic speed and improve safety.

  11. MS transport assays for γ-aminobutyric acid transporters--an efficient alternative for radiometric assays.

    Transport assays for neurotransmitters based on radiolabeled substrates are widely spread and often indispensable in basic research and the drug development process, although the use of radioisotopes is inherently coupled to issues concerning radioactive waste and safety precautions. To overcome these disadvantages, we developed mass spectrometry (MS)-based transport assays for γ-aminobutyric acid (GABA), which is the major inhibitory neurotransmitter in the central nervous system (CNS). These "MS Transport Assays" provide all capabilities of [(3)H]GABA transport assays and therefore represent the first substitute for the latter. The performance of our approach is demonstrated for GAT1, the most important GABA transporter (GAT) subtype. As GABA is endogenously present in COS-7 cells employed as hGAT1 expression system, ((2)H6)GABA was used as a substrate to differentiate transported from endogenous GABA. To record transported ((2)H6)GABA, a highly sensitive, short, robust, and reliable HILIC-ESI-MS/MS quantification method using ((2)H2)GABA as an internal standard was developed and validated according to the Center for Drug Evaluation and Research (CDER) guidelines. Based on this LC-MS quantification, a setup to characterize hGAT1 mediated ((2)H6)GABA transport in a 96-well format was established, that enables automated processing and avoids any sample preparation. The K(m) value for ((2)H6)GABA determined for hGAT1 is in excellent agreement with results obtained from [(3)H]GABA uptake assays. In addition, the established assay format enables efficient determination of the inhibitory potency of GAT1 inhibitors, is capable of identifying those inhibitors transported as substrates, and furthermore allows characterization of efflux. The approach described here combines the strengths of LC-MS/MS with the high efficiency of transport assays based on radiolabeled substrates and is applicable to all GABA transporter subtypes.

    Transportation takes a considerable and increasing fraction of the energy use worldwide, and more than half the oil consumption. By far the largest part is used by cars powered by internal combustion engines. The advantage of using internal combustion engines is that the energy density of liquid fuels is extremely high. The disadvantage is that gasoline and diesel engines have a poor performance: 20 to 25% only. How does this compare with electric cars? What are the alternative transportation systems and their efficiencies anyway? In this lecture we analyse the efficiency of various transport systems, using elementary physics principles. We will look at cars, buses, trains and TGVs, ships and aircraft. In addition, the efficiency of human powered vehicles will be considered. New and promising developments in the field of Intelligent Transportation Systems, like Cooperative Adaptive Cruise Control, are also discussed.

    Electron heat transport in low-collisionality LHD plasma is investigated in order to study the neoclassical transport optimization effect on thermal plasma transport with an optimization level typical of so-called ''advanced stellarators''. In the central region, a higher electron temperature is obtained in the optimized configuration, and transport analysis suggests the considerable effect of neoclassical transport on the electron heat transport assuming the ion-root level of radial electric field. The obtained experimental results support future reactor design in which the neoclassical and/or anomalous transports are reduced by magnetic field optimization in a non-axisymmetric configuration.

    In this paper we claim that distance alone is a poor proxy for international transport costs in empirical studies. We model a manufacturing and a transport sector and let the level of manufacturing exports determine the demand for transport services. Above a particular trade level, transport service suppliers find it profit-maximizing to invest in an advanced transport technology, which lowers their marginal costs and as a consequence, equilibrium transport prices. Transport costs thus vary w...

  15. Natural hazard impacts on transport systems: analyzing the data base of transport accidents in Russia

    Science.gov (United States)

    Petrova, Elena

    2015-04-01

    We consider a transport accident as any accident that occurs during transportation of people and goods. It comprises of accidents involving air, road, rail, water, and pipeline transport. With over 1.2 million people killed each year, road accidents are one of the world's leading causes of death; another 20-50 million people are injured each year on the world's roads while walking, cycling, or driving. Transport accidents of other types including air, rail, and water transport accidents are not as numerous as road crashes, but the relative risk of each accident is much higher because of the higher number of people killed and injured per accident. Pipeline ruptures cause large damages to the environment. That is why safety and security are of primary concern for any transport system. The transport system of the Russian Federation (RF) is one of the most extensive in the world. It includes 1,283,000 km of public roads, more than 600,000 km of airlines, more than 200,000 km of gas, oil, and product pipelines, 115,000 km of inland waterways, and 87,000 km of railways. The transport system, especially the transport infrastructure of the country is exposed to impacts of various natural hazards and weather extremes such as heavy rains, snowfalls, snowdrifts, floods, earthquakes, volcanic eruptions, landslides, snow avalanches, debris flows, rock falls, fog or icing roads, and other natural factors that additionally trigger many accidents. In June 2014, the Ministry of Transport of the RF has compiled a new version of the Transport Strategy of the RF up to 2030. Among of the key pillars of the Strategy are to increase the safety of the transport system and to reduce negative environmental impacts. Using the data base of technological accidents that was created by the author, the study investigates temporal variations and regional differences of the transport accidents' risk within the Russian federal regions and a contribution of natural factors to occurrences of different

    The local electron and ion heat transport as well as the particle and impurity transport properties in stellarators are reviewed. In this context, neoclassical theory is used as a guideline for the comparison of the experimental results of the quite different confinement concepts. At sufficiently high temperatures depending on the specific magnetic configuration, neoclassical predictions are confirmed by experimental findings. The confinement properties in the LMFP collisionality regime are discussed with respect to the next stellarator generation, for which at higher temperatures the neoclassical transport is expected to become more important.
