    This article first discusses how information technologies are changing the way knowledge is delivered at universities worldwide. Then, the article reviews some of the most popular learning management systems available today and some of the most useful online resources in the areas of Mathematics and Statistics. After that, some long-term experiences regarding the teaching of online courses in those areas at the Open University of Catalonia are discussed. Finally, the article presents the results of a large-scale survey performed in Spain that aims to reflect instructors' opinions and feelings about potential benefits and challenges of teaching mathematics online, as well as the role of emergent technologies in the context of the European Area of Higher Education. Therefore, this article contributes to the existing literature as an additional reference point, one based on our long-term experience in a large-scale online environment, for discussions involving mathematical e-learning.

  2. Tracking Point of View in Narrative

    Wiebe, J M

    1994-01-01

    Third-person fictional narrative text is composed not only of passages that objectively narrate events, but also of passages that present characters' thoughts, perceptions, and inner states. Such passages take a character's ``psychological point of view''. A language understander must determine the current psychological point of view in order to distinguish the beliefs of the characters from the facts of the story, to correctly attribute beliefs and other attitudes to their sources, and to understand the discourse relations among sentences. Tracking the psychological point of view is not a trivial problem, because many sentences are not explicitly marked for point of view, and whether the point of view of a sentence is objective or that of a character (and if the latter, which character it is) often depends on the context in which the sentence appears. Tracking the psychological point of view is the problem addressed in this work. The approach is to seek, by extensive examinations of naturally-occurring narra...

  6. The educator's point of view.

    Dengo De Vargas, M E

    1993-03-01

    Education is considered as an important means of promoting social change, and within this context how population issues can be integrated into development planning and educational practices is discussed. Education is expected to have an impact in future years, and is a necessary means of creating awareness of population-related problems; education for all is a human right. New approaches to population education must include teacher training and creation of awareness about population issues that respect cultural identity and free choice and do not influence customs and values that would run counter to the society. Educators have an ethical responsibility to address issues of population and human life; when seeking outside expertise, the nation should not be "carried away by the pressures of financial agencies which respond to foreign interests." For instance, the psychosocial dynamics and practice of sexual intercourse in Central America are different from those in North America or Europe. Sexual education must be based on sound scientific approaches, but must also include ethical values. Population education must use a holistic, intersectoral approach. Nations have human, natural, and economic resources, which must have a balanced influence. Human development involves being both the object and planner of development. Pope John Paul II noted that development must include the biological, the psychosocial, and the spiritual and reach all men. Human rights must be guaranteed. In addition to equality for women everyone has the right to dignity, education, employment, health, housing, and leisure. Quality of life is a part of human development, and is achieved through a balance between man, his environment, and resources, and liberty and peace. Educational strategies involve macro planning for placement and number of schools and teachers, and decentralizing educational services in order to reach rural areas. Formal and informal education is required. Adult education is

  7. Irradiation: Consumers' point of view

    International Nuclear Information System (INIS)

    The various potential reactions of consumers to irradiated foods are enumerated, with consideration being given to significant factors that will influence acceptance such as accentuation of freshness, just sufficient information (since the consumer wants a few reassuring facts, not too many technical details and a good reason to buy the product), assurance of safety, taste and appearance of the products, assurance of correct treatment under product conditions that will ensure the expected benefit, and indication of the expiry date (to ensure that shelf life used up in new transportation and distribution shcedules is clear to the consumer), assurance that the nutritional value has not been affected, competitive pricing - particularly where the handler has benefited from part of the shelf life extension, and information as to the benefits to the economy (lower food spoilage). Some steps taken in Canada to promote the technology and its acceptance by consumers were: adoption of the Codex Standard and Recommended Code of Practice, assurance of proper industry performance, and a decision to develop an appropriate symbol to designate irradiated food in a clearly recognisable manner, without unduly antagonizing the consumer. The Consumer's Association has acted to allay consumers' fears by supplying information to all media and by providing speakers at Seminars. It is now the task of industry to use ''marketing experts'' to further the education and selling process, and to tell the facts in simple concise terms. (author)

  9. A point's point of view of stringy geometry

    International Nuclear Information System (INIS)

    The notion of a 'point' is essential to describe the topology of spacetime. Despite this, a point probably does not play a particularly distinguished role in any intrinsic formulation of string theory. We discuss one way to try to determine the notion of a point from a worldsheet point of view. The derived category description of D-branes is the key tool. The case of a flop is analyzed and Π-stability in this context is tied in to some ideas of Bridgeland. Monodromy associated to the flop is also computed via Π-stability and shown to be consistent with previous conjectures. (author)

  11. The Software Point of View

    CERN Multimedia

    Bentvelsen, Stan

    Physics was meant to be the topic of the LUND workshop, but it was software that dominated throughout the week. ATLAS' new software proves a tough nut to crack. Many presented physics analyses were repetitions of the Physics TDR, using (or trying to use) the new software. The main purpose was to demonstrate that results were invariant with new software. Hard to prove since the 'new software' is not yet completed. Nevertheless the so far existing sofware is massively experimented with throughout the entire ATLAS community. So what does this "new software" really mean? The answer depends strongly on the person who deals with this question. The scope varies between "migrating from Fortran77 to C++" and "learn Object Oriented approach" to "implementing services and algorithms in Athena" or "feeding detector description in FADS". Clearly the new software primarily involves migrating from the old Fortran code to C++ with its object oriententation paradigm. Occasionaly there was a hint that this migration is not c...

  12. Features of Point Clouds Synthesized from Multi-View ALOS/PRISM Data and Comparisons with LiDAR Data in Forested Areas

    2014-01-01

    LiDAR waveform data from airborne LiDAR scanners (ALS) e.g. the Land Vegetation and Ice Sensor (LVIS) havebeen successfully used for estimation of forest height and biomass at local scales and have become the preferredremote sensing dataset. However, regional and global applications are limited by the cost of the airborne LiDARdata acquisition and there are no available spaceborne LiDAR systems. Some researchers have demonstrated thepotential for mapping forest height using aerial or spaceborne stereo imagery with very high spatial resolutions.For stereo imageswith global coverage but coarse resolution newanalysis methods need to be used. Unlike mostresearch based on digital surface models, this study concentrated on analyzing the features of point cloud datagenerated from stereo imagery. The synthesizing of point cloud data from multi-view stereo imagery increasedthe point density of the data. The point cloud data over forested areas were analyzed and compared to small footprintLiDAR data and large-footprint LiDAR waveform data. The results showed that the synthesized point clouddata from ALOSPRISM triplets produce vertical distributions similar to LiDAR data and detected the verticalstructure of sparse and non-closed forests at 30mresolution. For dense forest canopies, the canopy could be capturedbut the ground surface could not be seen, so surface elevations from other sourceswould be needed to calculatethe height of the canopy. A canopy height map with 30 m pixels was produced by subtracting nationalelevation dataset (NED) fromthe averaged elevation of synthesized point clouds,which exhibited spatial featuresof roads, forest edges and patches. The linear regression showed that the canopy height map had a good correlationwith RH50 of LVIS data with a slope of 1.04 and R2 of 0.74 indicating that the canopy height derived fromPRISM triplets can be used to estimate forest biomass at 30 m resolution.

  13. INSPIRE from the JRC Point of View

    2012-12-01

    Full Text Available This paper summarises some recent developments in INSPIRE implementation from the JRC (Joint Research Centre point of view. The INSPIRE process started around 11 years ago and today, clear results and benefits can be seen. Spatial data are more accessible and shared more frequently between countries and at the European level. In addition to this, efficient, unified coordination and collaboration between different stakeholders and participants has been achieved, which is another great success. The JRC, as a scientific think-tank of the European Commission, has played a very important role in this process from the very beginning. This role is in line with its mission, which is to provide customer-driven scientific and technical support for the conception, development, implementation and monitoring of European Union (EU policies. The JRC acts as the overall technical coordinator of INSPIRE, but it also carries out the activities necessary to support the coherent implementation of INSPIRE, by helping member states in the implementation process. Experiences drawn from collaboration and negotiation in each country and at the European level will be of great importance in the revision of the INSPIRE Directive, which is envisaged for 2014.

    Full Text Available The concept of “true and fair view” is a very subjective one , which didn’t find yet the definition general accepted and in this way we can’t say that there are relevant instruments for measuring the level of the fidelity reflected in the financial statements. The financial audit plays an important role for delimitating the true and fair view supplied by the financial statements and despite the fact that the financial auditors are consciences that there isn’t a mathematical formula or other kind of formula through which could be possible to measure the level of the fidelity and the true and fair view of the financial statement, they consider that they have the possibility to identify the situations in which the financial statements didn’t present the reality true and fair, using the professional though to determine the level of the financial statements to give a true and fair view We have made an empirical survey which permits us to analyze the quality of the true and fair view supplied by the financial statements from the point of view of the financial auditor, without having the pretentious of using all the significant aspects.

  18. Suicide from a Holistic Point of View

    Directory of Open Access Journals (Sweden)

    Søren Ventegodt

    2005-01-01

    Full Text Available Suicide has been honoured and respected in the eastern culture, especially in Japan with the famous tradition of Hara-kiri, or seppuku, while in most western societies suicide has been seen negatively and many contemporary physicians tend to consider suicide the most self-destructive and evil thing a human being can do and something that should be avoided at all cost. Religions also have different viewpoints on suicide, but from a philosophical point of view we believe that considering the choice of life and dead to be extremely relevant for a good living. The choice of life and dead is real, since responsibility for life is necessary in order to live life and even the best physician cannot keep a patient alive, who deep inside wants to die. In this chapter, we present parts of a story of a young girl who had experienced child sexual abuse. In holistic existential therapy, it is our experience, when the patient is well supported in the confrontation of the fundamental questions related to assuming responsibility for the coherence, that this confrontation will almost always lead to a big YES to life. Without confronting the fundamental question of “to be or not to be”, life can never be chosen 100% and thus never be lived fully.

  19. Local or district heating by natural gas: Which is better from energetic, environmental and economic point of views?

    Lazzarin, R.; Noro, M. [Department of Management and Engineering, University of Padova, Stradella S. Nicola, 3-36100 Vicenza (Italy)

    2006-02-01

    Generally, a CHP plant coupled with district heating is considered more efficient than traditional local heating systems from an economic and environmental point of view. This is certainly true for municipal waste CHP plants, but for plants fuelled by natural gas the important developments of the last years regarding both boilers (premixed and modulating burners, condensing boilers, etc.) and mechanical vapour compression and absorption heat pumps can change the traditional view. At the same time also district heating plants improved. Therefore it is worth to analyse the whole matter comparing advantages and disadvantages of the different alternatives, with a wide difference between them. The paper reports on the analysis of major district heating natural gas based technologies (vapour and gas turbines, internal combustion engine, combined cycles); the cost of heat and power produced in these plants is compared to the cost of producing the same quantity of electrical energy by a reference GTCC-Gas Turbine Combined Cycle (actually the most efficient technology for pure electrical production) and the cost of heat production by modern local heating technologies using natural gas as fuel (condensing boilers, electrical, gas engine and absorption heat pumps). Regarding energy efficiency and emissions, modern local heating turns out to be more efficient than district heating for most CHP technologies. However, the same does not happen from an economic point of view, because in Italy natural gas used by cogeneration plants is subjected to a much lower taxation than local heating technologies.

  20. Habitability from a microbial point of view

    We examine here the definition of habitability from the point of view of primitive, anaerobic microorganisms noting that the conditions of habitability are different for the appearance of life, for established life, and for life in dormant mode [1]. Habitability in this sense is clearly distinguished from the 'prebiotic world' that precedes the appearance of life. The differences in the conditions of habitability necessary for life to appear, for life to flourish and for dormant life entrain differences in spatial and temporal scales of habitability. For the origin of life, the ingredients carbon molecules, water, nutrients and energy need to be present on time scales applicable for the origin of life (105 to a few 106 y ?), necessitating the spatial scales of a minimum of ~100 km. Established life can take advantage of short-lived habitats (hours, days) to much longer lived ones on spatial scales of 100s μm to cm-m, whereas dormant life can survive (but not metabolise) in extreme environments for very long periods (perhaps up to millions of years) at microbial spatial scales (100s μm - mms). Thus, it is not necessary for the whole of a planet of satellite to be habitable. But the degree of continued habitability will have a strong influence on the possibility of organisms to evolve. For a planet such as Mars, for instance, microbial habitability was (perhaps still is) at different times and in different places. Habitable conditions conducive to the appearance of life, established life and possibly even dormant life could co-exist at different locations. Reference: [1] F. Westall, D. Loizeau, F. Foucher, N.

    2014-09-01

    Full Text Available This article proposes to examine some theories of non-religious spirituality in light of the growing phenomenon of those individuals who declared themselves as having "no religion" by Brazilian religious census conducted in 2010 by the Brazilian Institute of Geography and Statistics (IBGE. The intention here is to identify how the poetic question presents itself as the fundamental element of these proposals about spirituality for authors, since beauty is part of the spiritual quest, as in: Viktor Frankl and existential religiosity grounded in the search for meaning in life; Marià Corbí and his non-religious or secular spirituality; Robert Solomon and his spirituality for skeptics, and André Comte-Sponville and his atheistic spirituality, or spirituality without God. From there, we then present the perception of spirituality in the poetry of the thought of Jean Paul Sartre, primarily in his work “what is Literature?”

    Full Text Available The rock art of the Mediterranean Arch (which includes what are conventionally called Levantine Rock Art, Schematic Rock Art and Macroschematic Rock Art, among other styles, designated as part of the Human Heritage in 1997, is studied from the point of view of the Archaeology of Landscape. The information sources used were field work, cartographic analysis and analysis in GIS, besides two Rock Art Archives: the UNESCO Document and the Corpus of Levantine Cave Painting (Corpus de Pintura Rupestre Levantina. The initial hypothesis was that this rock art was involved in the process of neolithisation of the Eastern part of Iberia, of which it is a symptom and a result, and it must be understood as an element of landscape construction. If this is true, it would have a concrete distribution in the form of locational patterns. Through statistical procedures and heuristical approaches, it has been demonstrated that there is a structure of the neolithic landscape, defined by rock art, which is possible to interpret functional and economically.

    Se estudia el arte rupestre del Arco Mediterráneo (que incluye a los convencionalmente conocidos como Arte Levantino, Arte Esquemático y Arte Macroesquemático, entre otros estilos, nombrado Patrimonio de la Humanidad en 1998, desde el punto de vista de su localización. Las fuentes de información utilizadas fueron trabajo de campo, revisión cartográfica y análisis en Sistema de Información Geográfica, además de dos archivos de arte rupestre: el Expediente UNESCO y el Corpus de Pintura Rupestre Levantina. La hipótesis inicial fue que este arte rupestre se imbrica en el proceso de neolitización del Levante peninsular, del que es síntoma y resultado, y debe entenderse como un elemento de construcción paisajística, de lo que se deduce que ha de presentar una distribución determinable en forma de patrones locacionales.

    Full Text Available This study aims to provide an overview of the citation rate of Wikipedia since its launch in 2004. It is worth noting that since its inception Wikipedia, the free international multi-lingual encyclopedia, has been subject to criticism (Fasoldt, 2004; Orlowski, 2005; Lipczynska, 2005. Wikipedia as a popular web resource appears in response to every keyword search on Google. One way to test the popularity of a web resource is to use citation analysis method to predict to what extend it is cited by scientific papers. This study tries to identify and quantify the number of citations to Wikipedia in the papers indexed by the ISI Web of Science, studying the citation behavior of authors who have published papers in journals indexed by this database. Another simple search was conducted in order to analyze the number of citations to Britannica in the Cited Work=(Britannica* AND Cited Year=(2004-2009. The result showed that Britannica was cited only 10 times by 10 different subject areas and only in English language documents. The data show that Wikipedia is cited 26 times more than Britannica. Although, the credibility and reliability of content of Wikipedia as an authoritative reference source was widely criticized (e.g., Lih, 2004; Andrew et al., 2005; Korfiatis, Poulos, & Bokos, 2006, it is cited more than Britannica. The significance of Wikipedia from a citation analysis point of view goes well beyond open access and enhanced opportunities for citation.

    The recent isolation of imprinted mammalian genes has at last allowed the analysis of the molecular controls that regulate monoparental gene expression. Remarkably, many expectations as to how the imprinting mechanism works have been confounded by these studies. As a result, the time now seems right to reconsider our current understanding of the nature of imprinting, and how best it can be defined. Here, I discuss the past and present understanding of imprinting in the light of results obtained from studies of endogenous imprinted genes, and finally propose that the current multiplicity of imprinting terms and definitions be replaced by a single term and definition.

    1998-01-01

    Full Text Available Proportional navigation is one of the most popular and one of the most used of the guidance laws. But the way it is studied is always the same: the acceleration needed to reach a known target is derived or analyzed. This way of studying guidance laws is called “the direct problem” by the authors. On the contrary, the problem considered here is to find, from the knowledge of a part of the trajectory of a maneuvering object, the target of this object. The authors call this way of studying guidance laws “the inverse problem”.

    2012-01-01

    Near the event horizon of a black hole, the effective theory is two dimensional conformal theory. Here we show that the holographic modes characterising this underlying conformal symmetry and the basic definition of entropy $S$ in statistical mechanics lead the equipartition law of energy. We also show that $S$ is proportional to the gravity action which suggests the emergent nature of gravity. This is further bolstered by expressing the generalised Smarr formula as a thermodynamic relation, ...

    Discussions of disability should be within a clearly-defined moral framework if the disabled person's rights are to be translated into society's duty to the disabled. An ethical system based on modern versions of utilitarianism is suggested as a moral framework, supplemented by prescriptions based on social justice and respect. (Author/CB)

  18. Seismic Progressive Collapse: Qualitative Point of View

    2009-01-01

    Full Text Available Progressive collapse is a catastrophic structural phenomenon that can occur because of human-made and natural hazards. In progressive collapse mechanism, a single local failure may cause a significant deformation which then may lead to collapse of a structure. The current practices in progressive collapse analysis and design method generally focus on preventing progressive collapse due to abnormal gravity and blast loads. Progressive collapse behaviour of structures due to earthquake loads has not received as much attention. This paper presents a brief overview of the current state-of-knowledge, insights, and issues related to progressive collapse behaviour of structures caused by earthquake loading.

  19. Reversibility: An Engineer's Point of View

    International Nuclear Information System (INIS)

    Reversibility is the most consistent option in a democratic country. However reversibility may also have several drawbacks which must be identified and mitigated. Reversibility of a geological repository is a relatively new idea in France. The 1991 law dedicated to nuclear waste management considered reversibility as a possible option. Fifteen years later, the 2006 law mandated that a deep repository must be reversible and that the exact content of this notion should be defined by a new law to be discussed by the Parliament in 2015. Reversibility was not a concern put forward by engineers. It clearly originated from a societal demand sponsored and formulated by the Parliament. Since 1991, the exact meaning of this mandate progressively became more precise. In the early days, reversibility meant the technical and financial capability to retrieve the wastes from the repository, at least for some period of time after being emplaced. Progressively, a broader definition, suggested by Andra, was accepted: reversibility also means that a disposal facility should be operated in such a way that a stepwise decision-making process is possible. At each step, society must be able to decide to proceed to the next step, to pause or to reverse a step. Several benefits can be expected from a reversible repository. Some technical safety concerns may be only recognised after waste emplacement. Radioactive wastes may become a resource whose recoverability is desirable. Regulations may change, alternative waste treatment or better disposal techniques may be developed, or the need to modify a component of the facility may arise. Looking back at how chemical or domestic wastes were managed some 50 years ago easily underscores that it is not unreasonable to hope for significant advances in the future. For scientists and engineers, reversibility proves to have several other merits. To design and build a good repository, time is needed. The operator of a mine or of an oil field knows that

    Full Text Available Psychotherapy is a general name of interventions used to resolve emotional conflicts, support and sustain the improvement of mental health. Relationship is one of the most important factors of regenerative effect in psychotherapy. Understanding the client is crucial to help the client understand the psychotherapy and psychotherapist. Thus, in order to be effective in psychotherapeutic interventions, it is neccessary to use the language by considering the client’s believes, culture, religion and background. Comprehending and using of psychotherapy only from the Western point of view could reduce the efficacy of psychotherapy. Although, it is common that people working in mental health area learn and use the techniques of authorities lived in West, our culture is considerably wealthy of thoughts and aspects that can be used in psychotherapy. Raised on the lands that have extremely rich cultural heritage, as psychotherapists, we think that it is our responsibility to integrate modern psychotherapy with cultural heritage when learning, practicing and teaching the practice of psychotherapy. In this article, it is aimed to increase the awareness of being able to use the philosophy of Mevlana Celaleddin Rumi whose masterpieces involve psychotherapeutic elements yet are not well understood and who has been an inspration to the trends in psychotherapy which are currently described as third generation trends

  1. The temperatures of Giordano Bruno crater observed by the Diviner Lunar Radiometer Experiment: Application of an effective field of view model for a point-based data set

    2016-07-01

    Point based planetary datasets are typically stored as discrete records that represent an infinitesimal location on the target body. Instrumental effects and spacecraft motion during integration time can cause single points to inadequately represent the total area on the target that contributes to an observation. Production of mapped data products from these data for scientific analysis proceeds by binning points onto rectangular grids. Empty bins occur where data coverage is insufficient relative to grid resolution, a common problem at high latitudes in cylindrical projections, and remedial interpolation can lead to high uncertainty areas and artifacts in maps. To address such issues and make better use of available data, we present a method to calculate the ground-projected effective field of view (EFOV) for point-based datasets, using knowledge of instrumental characteristics and observation geometry. We apply this approach to data from the Lunar Reconnaissance Orbiter (LRO) Diviner Lunar Radiometer Experiment, a visible to far-infrared multispectral radiometer which acquires radiometric measurements of reflected visible and emitted infrared radiation of the Moon in 9 spectral channels between 0.35 and 400 μm. Analysis of gridded radiance from crater Giordano Bruno, a 22 km diameter rayed crater, is used to demonstrate our gridding procedure. Diviner data, with such processing, reveals details of the surface that are seen in the high-resolution LRO Camera NAC images. Brightness temperatures and anisothermality observed in Diviner's IR channels show the thermophysical properties of the crater ejecta to be very heterogeneous indicative of minimal mechanical disruption by micrometeoroid impacts consistent with a very young (lunar surface becomes rapidly homogenized over time. This heterogeneity has implications for crater-count studies as regions of high anisothermality are characterized by large blocks of material and lower crater densities.

    Full Text Available Parenteral nutrition—a form of administering nutrients, electrolytes, trace elements, vitamins, and water—is a widely used mode of therapy applied in many diseases, in patients of different ages both at home and in hospital. The success of nutritional therapy depends chiefly on proper determination of the patient’s energetic and electrolytic needs as well as preparation and administration of a safe nutritional mixture. As a parenterally administered drug, it is expected to be microbiologically and physicochemically stable, with all of the components compatible with each other. It is very difficult to obtain a stable nutritional mixture due to the fact that it is a complex, two-phase drug. Also, the risk of incompatibility between mixture components and packaging should be taken into consideration and possibly eliminated. Since parenteral nutrition is a part of therapy, simultaneous use of drugs may cause pharmacokinetic and pharmacodynamic interactions as well as those with the pharmaceutical phase. The aim of this paper is to discuss such aspects of parenteral nutrition as mixture stability, methodology, and methods for determining the stability of nutritional mixtures and drugs added to them.

    Primordial nucleosynthesis remains as one of the pillars of modern cosmology. It is the test-ing ground upon which all cosmological models must ultimately rest. It is our only probe of the universe during the first few minutes of cosmic expansion and in particular during the important radiation-dominated epoch. These lectures review the basic equations of space-time, cosmology, and big bang nucleosynthesis. We will then review the current state of observational constraints on primordial abundances along with the key nuclear reactions and their uncertainties. We summarize which nuclear measure-ments are most crucial during the big bang. We also review various cosmological models and their constraints. In particular, we summarize the constraints that big bang nucleosynthesis places upon the possible time variation of fundamental constants, along with constraints on the nature and origin of dark matter and dark energy, long-lived supersymmetric particles, gravity waves, and the primordial magnetic field.

    Full Text Available Myeloid Sarcoma may occur in patients with an acute or chronic myeloproliferative disorder as well as de novo, with no apparent sign or symptom of concomitant haematological disease. The patients are preferentially young male and the site of disease localization may vary from central nervous system to pleura and thorax, with a common involvement of the reticuloendothelial system. The disease often shows chromosomal rearrangements, involving chromosomes 7, 8 and 3 and sometimes a complex karyotype (more than 3 abnormalities is detected at diagnosis. The prognosis of this disease is dismal and only high-dose chemotherapy with autologous or allogeneic stem cells transplantation (auto or allo-SCT may be potentially curative. In the absence of definitive elements that can define the prognosis of extra-medullary localization of “standard risk” AML, Clinicians should pursue the collection of data from different Centres and design of homogeneous treatment strategies, that could integrate standard chemotherapy with specific approaches, such as radiotherapy, transplant procedures or, in selected cases (such as those displaying molecular abnormalities involving protein tyrosine-kinases, molecularly targeted therapies.

    Full Text Available This paper is an expository contribution reporting on published work. It focusses on an approach followed in the rewriting community to formalize the concept of strategy. Based on rewriting concepts, several definitions of strategy are reviewed and connected: in order to catch the higher-order nature of strategies, a strategy is defined as a proof term expressed in the rewriting logic or in the rewriting calculus; to address in a coherent way deduction and computation, a strategy is seen as a subset of derivations; and to recover the definition of strategy in sequential path-building games or in functional programs, a strategy is considered as a partial function that associates to a reduction-in-progress, the possible next steps in the reduction sequence.

  14. View Dependent Sequential Point Trees

    2006-01-01

    Sequential point trees provide the state-of-the-art technique for rendering point models, by re-arranging hierarchical points sequentially according to geometric errors running on GPU for fast rendering. This paper presents a view dependent method to augment sequential point trees by embedding the hierarchical tree structures in the sequential list of hierarchical points. By the method, two kinds of indices are constructed to facilitate the points rendering in an order mostly from near to far and from coarse to fine. As a result, invisible points can be culled view-dependently in high efficiency for hardware acceleration, and at the same time, the advantage of sequential point trees could be still fully taken. Therefore, the new method can run much faster than the conventional sequential point trees, and the acceleration can be highly promoted particularly when the objects possess complex occlusion relationship and viewed closely because invisible points would be in a high percentage of the points at finer levels.

  15. The Internal Point of View as a Rational Choice?

    Directory of Open Access Journals (Sweden)

    Michael Baurmann

    2009-01-01

    Full Text Available H. L. A. Hart's seminal book The Concept of Law entails arguments which are also of substantial importance for social theory: his claim that the existence of social and legal norms presupposes the dissemination of an internal point of view among the members of a social and legal community presents a serious challenge for any explanation of social order. Hartmut Kliemt emphasizes this aspect of Hart's work time and again in his own writings - and surely with very good reasons. In my paper I will try to reconstruct Hart's theory in detail. I will argue that we have to clarify the different dimensions of the concept of an internal point of view to be able to assess its consequences for a theory of social and legal order - especially for a rational choice approach which at first sight seems to be incompatible with the concept of an internal point of view.

    The Great Gatsby is Fitzgerald's finest novel, which was published in 1925, and Eliot considered it "to be the first step that America has taken since Henry James". It is a sensitive and symbolic treatment of themes of contemporary life related with irony and pathos to the legendry of "American dream". In this novel, Fitzgerald used many techniques: the controlled and detached point of view, the crafted structure and symbolism, all these distinguish The Great Gatsby from the style of his earlier works.However, in this paper I want to present my ideas of the detached point of view in The Great Gatsby. During my presentation, I have quoted some materials from critics to support my arguments. In the conclusion part, I also repeat my own opinion: the detached point of view, made The Great Gatsby the "small" masterpiece of American literature.

    2011-01-01

    The talk was done at the International Conference "Analysis, Topology and Applications", Harbin, China, 23.08.2011. Transitive Lie algebroids have specific properties that allow to look at the transitive Lie algebroid as an element of the object of a homotopy functor. Roughly speaking each transitive Lie algebroids can be described as a vector bundle over the tangent bundle of the manifold which is endowed with additional structures. Therefore transitive Lie algebroids admits a construction of inverse image generated by a smooth mapping of smooth manifolds. The intention of my talk is to use a homotopy classification of transitive Lie algebroids due to K.Mackenzie (2005) and on this basis to construct a classifying space. The realization of the intention allows to describe characteristic classes of transitive Lie algebroids form the point of view a natural transformation of functors similar to the classical abstract characteristic classes for vector bundles and to compare them with that derived from the Chern...

    The objective of the present study is to investigate the perspective of mothers regarding the care given by academics of nursing to their newborn in a neonatal intensive therapy unit. This is a qualitative research based on a phenomenological approach which has as its philosophical framework the thought of Martin Heidegger expressed in his book Being and Time. The data used in the investigation were interviews given by ten mothers who had their newborns in a neonatal intensive therapy unit of a university hospital in the city of Rio de Janeiro. The interpretation of the data collected revealed that mothers viewed the nursing academics as solicitous beings regarding the care given to their newborns. They also acknowledged that these students were engaged in the assistance given and concerned with what was being done and to whom it was being done. PMID:12098862

  3. Differences in the interpretation of the GLP requirements by OECD monitoring authorities: the point of view from the pharmaceutical industry.

    Science.gov (United States)

    Lowing, Raymond K

    2008-01-01

    The need to harmonise the principles of good laboratory practice (GLP), their application and their monitoring has always been a preoccupation of the authorities. This can be seen by the very early publication of the set of Organisation for Economic Co-operation and Development (OECD) documents, the training of the national inspectors, and the system of joint mutual visits. These aspects are now, for the most part, aligned. However, often the expectations of the inspectors and the interpretation behind the text are different and sometimes even opposite. In Sanofi-Aventis there is an almost unique position having 12 research and development sites in 7 different countries, all performing phases of studies which can be used by any of the other sites and all inspected by monitoring authorities (MAs) of the OECD GLP system. As with most international pharmaceutical companies a large majority of studies are multisite and even multicountry. This paper illustrates some of the challenges which are encountered when a global system of high quality is established to satisfy all the expectations of the multiple MAs, with particular reference to the diversity of origins of the requirements, specific guidance documents on GLP, question and answer sessions on GLP interpretations, annex requirements on specific areas (21 CFR Part 11, veterinary legislation etc.) and conference presentations by MAs. It is important to realize that even though there might be interpretations that the industry has some difficulty in understanding, the objective of this paper is not to complain or to criticize one or other of the MAs. Rather, the objective is to try to be constructive and to show where there are differences so that industry and the MAs can work together to establish systems which possess the level of quality necessary to ensure the safety of patients and the marketing of efficient products.

The laboratory measurements of the programme in logistics engineering are performed in this laboratory, and they are supplemented by the theoretical and practical measurements in the ‘Robotic Technology Assembly Laboratory', the ‘Power Electronics Laboratory', the ‘Mechatronics Laboratory', the ‘CAD/CAM Laboratory' and the ‘Acoustics and Product Laboratory'. The bodies of knowledge connected with environment protection and sustainable development can be grouped around three large topic areas. In environmental economics the objective is to present the corporate-organisational aspects of environmental management. Putting environmental management in the focal point, the objective of the programme is to impart knowledge that can be utilised in practice which can be used to shift the relation between the organisation and its environment in the direction of sustainability. The tools include environmental controlling, environmental marketing and various solutions of environmental performance evaluation. The second large topic area is globalization and its logistic aspects. In the field of global logistics the following knowledge carries special weight: logistic challenges in a globalised world; the concept of global logistics, its conditions and effects; delayed manufacture, assembly, packaging; the economic investigation of delayed assembly; globalised purchase and distribution in logistics; the logistic features of the globalised production supply/distribution chain; meta-logistics systems; logistics-related EU harmonisation issues; the effect of e-commerce on the global logistic system; logistic

Point of view (PoV) interviewing is an elicitation technique used in the social sciences as a means of enriching data obtained from research interviews. Recording research subjects' first person perspectives, for example by wearing digital video glasses, can afford deeper insights into their experiences. PoV interviewing can promote making visible the unverbalizable and does not rely as much on memory as the traditional interview. The use of such relatively inexpensive technology is gaining interest in health profession educational research and pedagogy, such as dynamic simulation-based learning and research activities.

    CONTEXT: The quiet Sun magnetic fields produce ubiquitous bright points (BPs) that cover a significant fraction of the solar surface. Their contribution to the total solar irradiance (TSI) is so-far unknown. AIMS: To measure the center-to-limb variation (CLV) of the fraction of solar surface covered by quiet Sun magnetic bright points. The fraction is referred to as 'fraction of covered surface', or FCS. METHODS: Counting of the area covered by BPs in G-band images obtained at various heliocentric angles with the 1-m Swedish Solar Telescope on La Palma. Through restoration, the images are close to the diffraction limit of the instrument (~0.1 arcsec). RESULTS: The FCS is largest at disk center (~1 %), and then drops down to become 0.2 % at 'mu'= 0.3 (with 'mu' the cosine of the heliocentric angle. The relationship has large scatter, which we evaluate comparing different subfields within our FOVs. We work out a toy-model to describe the observed CLV, which considers the BPs to be depressions in the mean solar ...

    Full Text Available Desde sua entrada em vigor, o Estatuto da Criança e do Adolescente sofre sistemáticas críticas no debate público não havendo, entretanto, no campo da doutrina especializada e da jurisprudência efetivos esforços para uma compreensão do alcance da lei e de seus princípios sobretudo quando o tema é a imposição de medidas de internação a adolescentes autores de infração penal. Este texto procura demonstrar a feição homogênea e estável da jurisprudência brasileira nos Tribunais Estaduais nessa matéria à luz dos principais argumentos utilizados como fundamentação das decisões em sede recursal. Alguns resultados da pesquisa "Responsabilidade e garantias ao adolescente autor de ato infracional: uma proposta de revisão do ECA em seus 18 anos de vigência" apoiada pela Secretaria de Assuntos Legislativos do Ministério da Justiça, ilustram as dificuldades de mplementação dos preceitos legais, possibilitando refletir se é a textura aberta da lei o que vem favorecendo a persistência de argumentos extrajurídicos e ideológicos em sua interpretação.Since its approval, The Child and Adolescent Act has been attacked for several critics in the public debate. However neither the specialized dogmatic nor jurisprudence have presented effective efforts to the comprehension of the law or its principles, especially related to internment measures applied to young offenders. the text shows the homogeneous appearance of the brazilian jurisprudence into the State Courts, according to the most used arguments by the decisions. some results from the "Responsibility and Guarantees to young offender: a revision proposal for the child and adolescent act in 18 years of existence" research illustrate these difficulties to implement the legislation, avoiding the consideration regarding the open texture of the law as a possible cause for the persistence of extralegal and ideological arguments on its interpretation.

  11. Etiology of cicatricial alopecias: a basic science point of view.

    McElwee, Kevin J

    2008-01-01

    This article presents a short summary of our current knowledge of cicatricial alopecia disease pathogenesis and the hypothetical disease mechanisms that may be involved in scarring alopecia development. Several forms of scarring alopecia likely involve targeted cytotoxic action against hair follicle cells mediated by a folliculocentric inflammation. However, the specific nature of the inflammatory interference in hair follicle growth is open to question. A popular hypothesis of lymphocyte-mediated scarring alopecia development involves autoimmune targeting of hair follicle-specific self-antigens, although there is no direct evidence in support of such a view. Alternative hypotheses focus on defects in sebaceous gland function, destruction of hair follicle stem cells, and interference in the communication between hair follicle mesenchyme and epithelium. Many questions arise from these hypotheses, and addressing them with a systematic research approach may enable significant advances in understanding cicatricial alopecia etiology.

  13. R and R: The ASN Point of View

    International Nuclear Information System (INIS)

    after closure such as ventilation, sensors and gallery retaining structures, for example. 6) D uring the whole reversibility period, provisions have to be implemented in order to ensure that the necessary and useful information is collected, stored and accessible (on the package itself and on the conditions of its emplacement). Moreover, provisions for knowledge transfer related to reversibility management will have to be defined for the commissioning of the facility. 7) If the law on reversibility includes provisions on retrievability of the waste packages: - funding of the retrieval would have to be specified; - facilities have to be designed to store the packages and to re-condition them safely. From the safety point of view, retrievability can provide a possibility to retrieve a package already put in place and to re-condition it, should an anomaly be seen on it. But ASN stresses that before any retrieval is performed, an analysis of the risks in terms of radiation protection and safety during operation and in the long term as compared to awaited benefits will have to be performed. Reversibility is a complex issue which has to be shared socially and politically and which deserves to be thoroughly addressed. We consider that the flexibility and margin introduced by the reversibility principle, except major technical evolution not identified today, will decrease with time, in particular because of the evolution of the packages and of the facility with time

  16. Radiographic imaging of calcaneal fractures - the surgeons view point

    International Nuclear Information System (INIS)

    This paper presents a detailed description of calcaneal fractures, which are underestimated and neglected despite their relatively high frequency. In association with significant anatomic destruction of the calcaneus they lead to unsatisfactory results of fracture treatment. Radiographic features of a healthy calcaneal bone together with pathomechanism and radiographic attributes of most common fracture types are presented. The prognostic role of the posterior talo-calcaneal joint and extraarticular anatomy of the calcaneus are emphasized. Special attention is directed to the methods of calcaneal imaging, especially the most valuable in the authors opinion - lateral radiographic view and computed tomography. Other commonly used views: axial, antero-posterior or Broden, are also described, with explanation why they are rarely recommended. The widely used standard classification system for calcaneal fractures introduced by Sanders, based on computed tomography is presented. Correct x-ray imaging is the basis for further diagnostic workup and treatment, giving also valuable prognostic information. The orthopedic surgeon, who undertakes the difficult task of treating the broken calcaneus receives thorough information about bone damage, which helps to realize the consequences of injury and of possible negligence. According to the authors experience, problems discussed in this paper are rarely fully appreciated by radiologists and orthopedic surgeons resulting in, often, catastrophic consequences. (author)

    Full Text Available The paper concentrates on the topic of efficiency and effectiveness of company training. This work has set research goals that were solved using the interrogation method, questionnaire technique and free interview. Goal No. 1 was to investigate the situation in the company training from the motivation aspect and stimulating education system requirements. Goal No. 2 was to determine the use of educational methods, forms of training from the point of view of their efficiency. Goal No. 3 was to investigate into the attitude toward company training evaluation and exploitation of the individual levels of educational process efficiency evaluation. As a resource for the training efficiency evaluation the authors used Kirkpatrick’s 4-level Learning Evaluation Model extended with the ROI method. The research group consisted of a HR managers / managers from the SME sectors, b participants of these companies’ training programmes. The most important requirements for an efficient stimulating educational system involve the conformity with the needs and goals of the company, linking with the performance system and accord with the needs of an individual. The research has shown that in certain educational methods and forms there occurs conformity between the frequency of their usage in practice and apprehension of their efficiency, e.g. the controlled discussion method and the direct group education form. In others, such as the practical example method and individual consultation form, their usage in practice is minimal, but there is a high apprehension rate of their efficiency. The efficiency evaluation is implemented mostly only on the 1st and 2nd level (the reaction level and learning level. However, in a responsible approach to the efficient use of financial means invested into the training process also a shift of evaluation on the 3rd and 4th level (transfer to the work-place level and business result level and ROI are necessary.

    Full Text Available The dissertation discusses various documents on Java collected in Siku Quanshu (Complete Library of Four Treasures. The documents used as the sources of this study are the ones with complete pictures and strong narration on Javanese recorded from Han Dynasty (206 bc–220 ad to Ming Dynasty (1364–1644 in order to reveal what kind of historical knowledge or historical information is delivered by Chinese historians in general and what kind of point of view is used by historians to deliver the notes about Java. Through analytical reading, the readers will find that historians paid attention to three issues: the relationship between China and Java, the condition of Javanese kingdoms and their culture, and the Java land natural resources. People of China regard their country as an ancient country with long history of remarkable civilization which located in the centre of the world. The awareness of how important is their country, indirectly influences the historians’ points of views. The texts analyzed indirectly prove that some areas on Java are culturally left behind and the countries beyond China, including Java, are the barbaric ones obliging their people to submit or pay tributes to the Kingdoms of China.

  20. Strategic allocation of flight plans: an evolutionary point of view

    CERN Document Server

    Gurtner, Gérald

    2016-01-01

    We consider the simplified model of strategic allocation of trajectories in the airspace presented in a previous publication. Two types of companies, characterized by different cost functions, compete for allocation of trajectories in the airspace. We study how the equilibrium state of the model depends on the traffic demand and number of airports. We show that in a mixed population environment the equilibrium solution is not the optimal at the global level, but rather than it tends to have a larger fraction of companies who prefer to delay the departure time rather taking a longer routes. Finally we study the evolutionary dynamics investigating the fluctuations of airline types around the equilibrium and the speed of convergence toward it in finite populations. We find that the equilibrium point is shifted by the presence of noise and is reached more slowly.

    We analyse the results of our experimental laboratory approximation of motorways networks with slime mould Physarum polycephalum. Motorway networks of fourteen geographical areas are considered: Australia, Africa, Belgium, Brazil, Canada, China, Germany, Iberia, Italy, Malaysia, Mexico, The Netherlands, UK, USA. For each geographical entity we represented major urban areas by oat flakes and inoculated the slime mould in a capital. After slime mould spanned all urban areas with a network of its protoplasmic tubes we extracted a generalised Physarum graph from the network and compared the graphs with an abstract motorway graph using most common measures. The measures employed are the number of independent cycles, cohesion, shortest paths lengths, diameter, the Harary index and the Randic index. We obtained a series of intriguing results, and found that the slime mould approximates best of all the motorway graphs of Belgium, Canada and China, and that for all entities studied the best match between Physarum and ...

    qualified staff and increases the burden on residents may be reassigned to medical secretary or pathology assistants; therefore energy of residents can be saved for educational activities. Optimization of physical working conditions, assortment of training programs, rotation in lacking subjects and consultations will enhance the quality of the education of the resident. Feedback assessment of trainer and trainee is an essential part of a training program.In conclusion, an ideal resident from the resident's point of view is the person who is endowed with medical and pathological knowledge, orderly interrelates with staff, professionally communicates with clinicians, manages a laboratory and is trained hard to achieve all the above mentioned competencies.

  17. Response to the Point of View of Gregory B. Pauly, David M. Hillis, and David C. Cannatella, by the Anuran Subcommittee of the SSAR/HL/ASIH Scientific and Standard English Names List

    Science.gov (United States)

    Frost, Darrel R.; McDiarmid, Roy W.; Mendelson, Joseph R.

    2009-01-01

    The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

  18. [Demographic information in crisis: one point of view].

    Science.gov (United States)

    Morelos, J B

    1990-01-01

    This work argues that doubts concerning the reliability of demographic information in Mexico from censuses and other sources should prompt a search for ways of improving existing data rather than developing new data sources and measurement techniques. The example of labor force data is used to illustrate the achievements of past data collection efforts and to suggest a framework for reconciling statistics from diverse sources and exploiting existing sources more fully. From a practical perspective, it would be difficult to identify a nontraditional source of information, statistical procedure, or conceptual framework for collection of labor force and other demographic data that has not been tried somewhere, at some time. Economists and other social scientists who have analyzed the adequacy of existing data sources have pointed to the financial implications of extensive alterations in them and have suggested new questions to be added to censuses and surveys to fill gaps in information. Studies based on census data have been particularly effective in furthering understanding of the supply of labor in Mexico and the factors affecting behavior of the economically active population. Economic surveys have contributed to analysis of employment in the different sectors and the characteristics of workers in different types of establishments and activities. Surveys, both specialized and multipurpose, have also contributed to knowledge of employment and the labor market, especially in urban areas and in aspects related to migration. To classify the different potential sources of labor force data, 2 tables are presented. The 1st lists continuous, periodic, and sporadic sources of data produced in the public, social, and private sectors. The listing of different data sources suggests the rich potential for combining findings from different sources, e.g., correlating deaths occurring in a certain time period to working age adults with information derived from the census to

    2012-10-01

    The findings of empirical educational research and the theoretical and experiential knowledge of general didactics and specific didactics of relevant subjects are not adequately considered in the conception and implementation of patient education. The aim of this work is to screen the results of existing research about the quality of instruction, to deduce quality criteria for patient education and to discuss their benefits for the existing practice. The research on the quality of instruction was systematically investigated for this purpose. Subsequently, the 3 empirically validated quality features: "clear structure", "participant-oriented social climate" and "cognitive activation with particular attention to domain-specific components of teaching" we identified were transferred to patient education and concretized by including the theoretical and experiential knowledge of didactics. In the process several domains (conception of manuals, train-the-trainer seminars) were identified in which the quality characteristics can be tied in. The findings of empirical educational research are able to complement the existing measures for quality assurance in the area of patient education. For this purpose the identification and specification together with the possible integration of the 3 quality criteria in the area of patient education are a first step.

  1. Computer Crime and the Law from an Islamic Point of View

    Science.gov (United States)

    Al-A`Ali, Mansoor

    Information technology is facing waves of laws guarding the interest of people using the Web technology. These laws were derived from the common laws and legislations applied in general crimes. One of these laws is the law of the state is Texas in the United States in 1985. In a world which has more than one billion Muslims, it is time to consider proposing a law that is in line with their teachings. Several calls were also raised in the Islamic countries to establish a law suitable to handle computer crimes which matches the Islamic Shar'iah law. The main question to ask here is how can the Islamic law which was established in the seventh century handle crimes resulting from the use or abuse of the new technology and provide suitable laws for the protection of its computer users. To answer this question our research has analyzed the Adellah () (Shar'iah Evidences of Quraan, Hadith and Imams sayings) that match Texas computer crime law items to verify the outlook of Islam in computer crime. We set out to prove that computer crime with its high technology is not entirely a new type of crime that needs a new Islamic theory and thus is already covered by the general Islamic Shar'iah laws. Based on the available computer crime laws and our understanding of the Quranic verses, we propose to tackle this very difficult area by proposing a computer crime law from an Islamic point of view. We believe this research is the first of its kind and will open the discussion in this important area with the exception of one study which addresses the e-commerce from an Islamic view point.

  4. The CAREM-25 project from the risk point of view

    International Nuclear Information System (INIS)

    The future use of the nuclear energy for electricity production is considered a possible alternative, mainly taking into account the high environmental impact of the fossil fuel alternatives (greenhouse effect, acid rain). In a worldwide context, however, it is desirable for the new nuclear power plants to be safer than the present ones. To demonstrate the safety level of a nuclear installation, the Risk Analysis (in fact, Probabilistic Safety Analysis) is an adequate tool, as it allows for the risk level quantification. The risk itself is composed of two factors, the first takes into account the probability associated with accidental sequences that release radioactive materials, the second takes into account the amount and consequences of such a release. In the present work, the reduction of both factors is faced, the probability by using simpler safety systems (inherently safe systems), and the consequence by using small power production units, that have, besides, passive mitigation systems and long response times. The work is illustrated with a risk comparison for electricity production via CAREM-25 units, against via a classic design unit (Atucha II). The results are base in Probabilistic Safety Studies performed for both installations. The conclusions show an effective risk reduction (both in probability and in consequence), reaching the point where in no case acute irradiation effects are predicted in the vicinity of the accidented plant.

  5. Points of View and the reconciliation of Identity Oppositions: examples from the Maltese in Britain

    Directory of Open Access Journals (Sweden)

    Sammut, G.

    2010-01-01

    Full Text Available This paper presents the findings of a case study of Maltese migrants to Britain. In the absence of a cohesive community, Maltese migrants to Britain are required to negotiate a new social reality at the individual level. Previous research has demonstrated that individuals can relate to alternative perspectives in different ways (Sammut and Gaskell, 2010. The present study demonstrates that individuals with different points of view negotiate different identities that serve to position them functionally within one or both social realities. Individuals with monological points of view elaborated exclusive identities that positioned them well in a single social setting. Individuals with dialogical points of view elaborated hierarchical identities, holding their own bicultural identities as superior. This had further positioning ramifications. In contrast, individuals with metalogical points of view elaborated non- hierarchical, chameleon or individualistic identities, by which they positioned themselves functionally in both social settings. For metalogical types, belonging to one group meant that one was neither more nor less a member of the other group. These findings thus add a third type to Duveen’s dual- typology of identity strategies in the reconciliation of oppositional categories.

  6. Atypical Face Perception in Autism: A Point of View?

    Morin, Karine; Guy, Jacalyn; Habak, Claudine; Wilson, Hugh R; Pagani, Linda; Mottron, Laurent; Bertone, Armando

    Face perception is the most commonly used visual metric of social perception in autism. However, when found to be atypical, the origin of face perception differences in autism is contentious. One hypothesis proposes that a locally oriented visual analysis, characteristic of individuals with autism, ultimately affects performance on face tasks where a global analysis is optimal. The objective of this study was to evaluate this hypothesis by assessing face identity discrimination with synthetic faces presented with and without changes in viewpoint, with the former condition minimizing access to local face attributes used for identity discrimination. Twenty-eight individuals with autism and 30 neurotypical participants performed a face identity discrimination task. Stimuli were synthetic faces extracted from traditional face photographs in both front and 20° side viewpoints, digitized from 37 points to provide a continuous measure of facial geometry. Face identity discrimination thresholds were obtained using a two-alternative, temporal forced choice match-to-sample paradigm. Analyses revealed an interaction between group and condition, with group differences found only for the viewpoint change condition, where performance in the autism group was decreased compared to that of neurotypical participants. The selective decrease in performance for the viewpoint change condition suggests that face identity discrimination in autism is more difficult when access to local cues is minimized, and/or when dependence on integrative analysis is increased. These results lend support to a perceptual contribution of atypical face perception in autism. PMID:25683613

  7. Dental ethics in a larger context: one point of view.

    Science.gov (United States)

    Baumrind, Sheldon

    2007-01-01

    Since the end of World War II, the practice of dentistry has been largely transformed from a "calling" into a cog in the ever-expanding "Healthcare Industry". In the process, the distinction between professional ethics and the ethics of commerce has been attenuated and, to a large extent, lost. Today's dentist is faced with an inherent conflict between the pledge of the health professional to hold the patient's interests primary (and above all, to do no harm), and the self-protective commercial principle of caveat emptor. Pressures towards commercialism come from the government and the insurance industry, the increasingly unfavorable ratio between professional fees and the cost of production, and the high cost of dental education. Viewed simplistically, much of dentistry today has an outward form resembling commodity production. Recognizing the substantial forces tending to attenuate ethical standards in our profession may aid us in resisting their encroachments.

  8. Waste-to-energy: Technical, economic and ecological point of views

    International Nuclear Information System (INIS)

    Overwhelming waste-recycling should be considered more as a psychological than as a technological method to deal with wastes. The best waste disposal systems should actually grant mass or energy recovery from technical, economic and ecological point-of-views. Highest results seem to be granted by waste-to-energy technologies since energy content is the best preserved property after using materials

    The accurate location of one's virtual egocenter in a geometric space is of critical importance for immersion technologies. This experiment was conducted to investigate the role of field of view (FOV) and observer station points in the perception of the location of one's egocenter (the personal viewpoint) in virtual space. Rivalrous cues to the accurate location of one's egocenter may be one factor involved in simulator sickness. Fourteen subjects viewed an animated 3D model, of the room in which they sat, binocularly, from Eye Station Points (ESP) of either 300 or 800 millimeters. The display was on a 190 by 245 mm monitor, at a resolution of 320 by 200 pixels with 256 colors. They saw four models of the room designed with four geometric field of view (FOVg) conditions of 18, 48, 86, and 140 degrees. They drew the apparent paths of the camera in the room on a bitmap of the room as seen from infinity above. Large differences in the paths of the camera were seen as a function of both FOVg and ESP. Ten of the subjects were then asked to find the position for each display that minimized camera motion. The results fit well with predictions from an equation that took the ratio of human FOV (roughly 180 degrees) to FOVg times the Geometric Eye Point (GEP) of the imager: Zero Station Point = (180/FOVg)*GEP

  10. Marriage and Sexuality from a Psychiatric Point of View

    Directory of Open Access Journals (Sweden)

    Ali Bozkurt

    Full Text Available Sexuality, taking on a shape in the interaction of psychological, social, and biological variables, may lose its functionality with the blockage of these components. Sexual dysfunction may be handled as if it is only a symptom being based on the decay of marital relationship in the content of therapy, and sexual dysfunction may be neglected by family and marriage therapists from time to time. Contrarily, sex therapists may show the tendency to handle the problem in aspect of only sexuality. In the relationships of all spouses, thought and emotional intimacy should not be neglected whatever sexual problem they may have. Factors determining happiness such as physical attractiveness, impressiveness, positive and negative attitudes, marriage age, children, socioeconomic conditions, common intentions, and hobbies, sexual life, have attracted the attention of investigators for long time. Most important element among these factors seems to be sexuality. In recent years, researchers have begun to consider interaction between sexuality and marriage much more. Marital life includes food, shelter, togetherness, satisfaction originated from positive marital relationships, sharing role to cause of sexual maturation, acceptance of social role, and responsibility, individual entrepreneurship, and supporting to creativity. Marriage, consisting of spouses completing each other in these fields, is the headstone of social development and maturation. It has been suggested that there is a role of sexual dysfunction in protecting the balance of marital relationships. According to this suggestion, these disorders may prevent any damage to self and conserve the border of ego. Moreover, we may suggest that sexual dysfunction breaks the marital relationship, removes the protective effect on marital balance if we consider the beneficial effects of sexuality in points of intimacy in thought and emotional fields. Sexuality can be only experienced with healthy personality

    Full Text Available Abstrak : Isu imanensi dan transendensi sangat penting dalam pemikiran keagamaan. Salah satu alasan mengapa masalah ini tidak pernah terselesaikan adalah bahwa ia memiliki banyak makna dan muncul dalam konteks yang berbeda. Pandangan yang menekankan imanensi dalam satu konteks mungkin menekankan transendensi pada konteks lain. Arti keduanya pun sangat tergantung pada asumsi metafisik mereka yang biasanya secara tidak sadar menggunakannya. Dua sisi yang saling terkait dan bergantung satu sama lain ini pasti hadir di konsep pikiran, jika hubungan antara Allah dan alam semesta, Realitas dan penampilan, benar-benar untuk dipahami. Karena ketiadaanlah bahwa Allah digambarkan sebagai transenden (tanzīh, dan karena keberadaan sehingga Ia dikenal sebagai imanen (tashbīh. Dua aspek Tuhan, transenden dan imanen diringkaskan oleh Ibn ‘Arabi melalui pendekatan ayat Qur’an (42:11. Pakar sejarah agama, peneliti dan mistikus berpegang pada prinsip ini juga dan meyakini bahwa apa yang disebut sebagai “logika panggilan” memiliki dua sisi fungsi yang berarti. Menurut logika ini, seseorang harus mengklasifikasikan panggilan nabi pada kesatuan atau pluralitas seperti dalam kategorisasi panggilan transenden, imanen atau transenden-imanen, dan akibatnya adalah agama Ilahiah akan diperspesi dari sisi ini pula. “Fuzzy logic” atau logika fuzzy dipahami berdasarkan preposisi yang paradoks dari berbagai penjelasan dan analisa mistis.Kata kunci : Logika fuzzy, Transenden, Imanen, Teologi fuzzy, ParadoxAbstract : The issue of immanence and transcendence is crucial for religious thought. One reason why that is never resolved is that it has so many meanings and turns up in so many different contexts. A view may emphasize immanence in one context and emphasize transcendence in another. What the terms mean depends in part on the metaphysical assumptions, usually unconscious, of those who use them. According to Ibn al-Arabī, these two mutually dependent sides

    Kartaltepe, J. S.

    2002-12-01

    As an undergraduate at Colgate University, I have had many opportunities to get involved with research. I spent the summer after my first year on a project at Colgate that extended into a junior research course and I have also worked at two very different national programs (National Radio Astronomy Observatory at Green Bank and the Space Telescope Science Institute). As a result, I have gained research and observing experience at different observatories, including the Foggy Bottom Observatory at Colgate, Lowell Observatory, and the NRAO at Green Bank. From these diverse experiences I have learned a great deal about research in astronomy in general as well as what some aspects of the field are like specifically. For instance, I have learned about quasars, weak gravitational lensing, and HI absorption. I have come to appreciate things about astronomy that one never learns inside of a classroom. By having the chance to try out different types of research, I have gotten a better idea of what areas of research I might like to pursue in the future. These experiences have given me some highly beneficial skills for my future career in research.

  13. Skills renewal in nuclear an industrialist's point of view

    International Nuclear Information System (INIS)

    Global energy needs are increasing and at the same time, the use of fossil fuels for energy is being questioned for several reasons: the possible shortage of resources; the volatility of their prices; the impact of their use on global warming, to name but a few. Focusing on the demand for electricity, forecasts from the World Nuclear Association show a dramatically growing trend and a necessity for massive investments in response to this. Over the 2000-2030 period, the needs for extra electricity generation in Europe are estimated at 660 GW, in North America the forecasted level of needs is 850 GW, in China, it is 1,300 GW. Given the current fossil fuel situation, nuclear energy is undoubtedly part of the answer to the growing demand for electricity generation, along with renewable energies and energy efficiency. In most countries, nuclear power plants were commissioned over a relatively short period (1970-1985). Except maybe in some regions, the Chernobyl accident put this technology on hold for twenty years, meaning that an ageing workforce is now an issue for the nuclear industry. The recruitment of a significant number of engineers is thus necessary, both to launch new nuclear projects and to replace employees about to retire. In France, 40% of all nuclear engineers will retire over the next decade. During this period, around 1,200 engineers per year will be recruited, including 600 per year by EDF (a fourfold increase). In many countries, the recruitment of engineers has remained at a very low level for the past 15 years and consequently education programs have been cut back. Furthermore, teaching positions have not been renewed and only a few qualified individuals remain, most of whom are nearing retirement age. The revival of nuclear education is a key point for the success of the nuclear renaissance. In 2007-2008, the High Commissioner for Atomic Energy conducted a census of existing French nuclear teaching programs. By this time, capacity in France was

    Henriques de Figueiredo, B; Petit, A; Sargos, P; Kantor, G; Pouypoudat, C; Saut, O; Zacharatou, C; Antoine, M

    2015-10-01

    Adaptive radiotherapy is defined as all processes leading to the modification of a treatment plan on the basis of patient-specific variations observed during the course of a treatment. This concept is currently of particular relevance due to the development of onboard volumetric imaging systems, which allow for daily viewing of variations in both tumour and organs at risk in terms of position, shape or volume. However, its application in routine clinical practice is limited due to the demanding nature of the processes involved (re-delineation and replanning) and increased dependence on available human resources. Even if "online" strategies, based on deformable image registration (DIR) algorithms, could lead to a reduction in both work and calculation time, for the moment their use is limited to the research field due to uncertainties surrounding the validity of results gathered. Other strategies without DIR can be used as "offline" or "hybrid offline-online" strategies that seem to offer a compromise between time consumption and therapeutic gain for the patient.

    The paper gives an overview over the German energy policy in the area of renewable energy sources. It focuses on the Renewable Energies Act (REA) of April 1, 2000, which has shown to be the main stimulus for the upswing of the market of renewable energies in Germany. One of the key features of the REA is the declining compensation schedule that aims at generating and stimulating learning curve effects. The paper shows the key findings of a report to the German Bundestag on the market and on the cost trend of installations for the use of photovoltaics, wind power, biomass and hydropower. (author)

    When a catastrophic event strikes an urban area, many different professionals hit the ground running. Emergency responders respond, reporters report, and scientists and engineers collect and analyze data. Journalists and scientists may share interest in these events, but they have very different missions. To a journalist, earthquake damage is news. To a scientist or engineer, earthquake damage represents a valuable source of data that can help us understand how strongly the ground shook as well as how particular structures responded to the shaking.

    The phase shift induced by a uniform rotation in a Michelson interferometer is re-derived in the geometrical framework of the coordinate-free formalism of general relativity from the co-rotating point of view. The effect is second order in the ratio of the interferometer's speed to the speed of light and further suppressed by the ratio of the length of the interferometer's arms to the radius of rotation. The relation of the effect to gravitational time dilation is discussed.

    Full Text Available In Romania, a lot of practices proper to corruption became widely common and are integrated in a real national bureaucratic culture. Romanian citizens seem to accept and tolerate informal payments in order to obtain the desired or the necessary services. Public officials are doing well, impersonal and they don’t realize they affect social welfare. That’s why fight against corruption must involve complex actions performed on many areas. Such action must be focused on measures that reduce the opportunities for corruption and increase the probability of detection and punish the offences.

    2015-04-01

    Six Sigma and Lean are two quality improvement methodologies. The Lean Six Sigma methodology is applicable to repetitive procedures. Therefore, the use of this methodology in the health-care arena has focused mainly on areas of business operations, throughput, and case management and has focused on efficiency outcomes. After the revision of methodology, the paper presents a brief clinical example of the use of Lean Six Sigma as a quality improvement method in the reduction of the complications during and after lobectomies. Using Lean Six Sigma methodology, the multidisciplinary teams could identify multiple modifiable points across the surgical process. These process improvements could be applied to different surgical specialties and could result in a measurement, from statistical point of view, of the surgical quality.

  1. Deep tissue injury from a bioengineering point of view.

    Science.gov (United States)

    Gefen, Amit

    2009-04-01

    The phrasing of the National Pressure Ulcer Advisory Panel's (NPUAP) definition of deep tissue injury (DTI) was based on case reports, clinical observations, and experience. Although etiological studies of DTI, primarily related to characterizing biomechanical factors affecting onset and progression, support and strengthen parts of the NPUAP's definition, some recent findings suggest a need to re-evaluate the wording and perhaps refine future definitions of DTI. Application of existing bioengineering research to underlying biological, physical, biomechanical, and biochemical mechanisms involved in the definition of DTI suggests the following: 1) changes in skin color - ie, deviation of the local skin color from the surroundings - may indicate a DTI might be present, but color is not useful for quantifying the severity of injury; 2) the pressure and/or shear definition is inaccurate because it creates an artificial distinction between pressure and shear, which are physically coupled, and because it ignores tensional loads; 3) palpating tissue firmness at the wound site provides limited assessment information because tissue firmness will depend on the point in time along the course of DTI development. Damaged tissues might appear stiffer than surrounding tissues if examined when muscle tissue is locally contracted due to local rigor mortis but at a later stage damage might manifest as tissues that are softer than their surroundings when digestive enzymes start decomposing necrotic tissues; 4) skin temperature changes near the DTI site may reflect inflammatory response, causing local heating, or ischemic perfusion, causing local cooling; and 5) rapid deterioration of DTI is likely occurring due to muscle tissue stiffening at the rigor mortis phase; stiffened tissues abnormally deform adjacent tissues and this effect is amplified if muscles are atrophied. The application of interdisciplinary research may help clinicians and researchers move from evolving jargons

    2016-01-01

    Radiative power balance of a planet in the solar system is delineated. The terrestrial powers are transformed to average global flux in an effective atmospheric column (EAC) approximation, its components are delineated. The estimated and measured secular changes of the average global flux are compared to the fluxes derived from the Stefan-Boltzmann law using the observed global annual temperatures in the decades between 1880 and 2010. The conclusion of this procedure is that the radiative contribution of the greenhouse gas ${\\rm CO}_2$ is some $21\\pm 7$~\\% to the observed global warming from the end of the XIXth century excluding the feedback mechanisms playing determining role in the climate system. Stationary radiative flux transfer is treated in an air column as a function of the column density of the absorbent. Upper and lower limit of radiative forcing is given by assuming true absorption and coherent scatter of the monochromatic radiation. An integral formula is given for the outgoing long wave radiatio...

    Obstructive diseases of children's upper airways are frequent, mostly caused by tonsils and adenoids hypertrophy. A nasal septum deviation or a lower turbinate hypertrophy may also cause a significant obstruction. Tonsillectomy and adenoidectomy must be performed in case of clinical obstruction, sometimes documented by a sleep study. A tonsils' hypertrophy without significant obstruction and clinical symptoms is not an indication of adenotonsillectomy, even in case of snoring or if an orthodontic treatment is planned.

  5. Dark matter as seen from the physical point of view

    CERN Document Server

    Krasnoholovets, Vlodymyr

    2016-01-01

    It is shown that the Newton's law of universal gravitation can be derived from first submicroscopic principles inherent in the very nature of real space that is constituted as a tessellattice of primary topological balls. The submicroscopic concept determines the notion of mass in the tessellattice and introduces excitations of space, which appear at the motion of particles (mass particles are determined as local deformations of the tessellattice). These excitations are associated with carriers of the field of inertia. In the universe the gravitation is induced by standing inerton waves of mass objects, which oscillate around the objects with the speed of light. An overlapping of these standing inerton waves generates an elastic interaction between masses bringing them to a formation of clusters in which masses are characterised by both the Newtonian and elastic interaction. It is this elastic interaction that cancels the necessity of introduction of mystical dark matter. At the same time, inertons, carriers ...

  6. THINKING ABOUT RANDOM EVENTS FROM A LOGICAL POINT OF VIEW

    Directory of Open Access Journals (Sweden)

    Rosario D'Amico

    2013-06-01

    Full Text Available The purpose of this essay is to identify a meaningful property of random events by using a theorem introduced in an unconventional symbolic language, which we shall call ℒu. More precisely, we attempt to show that every random event must occur at least once. The method, which we use, consists in defining, by means of sentences of the language ℒu, the concept of random event, after showing that some statements about the structural proprieties of the sentences of ℒu can be translated into sentences of the language ℒu itself. Thanks to this peculiar feature of ℒu, we achieve an important gain in facilitating the identification of the propriety looked for. In fact, it is easier to deal with sentences of a formal system, free of concealed assumptions and possibly misleading associations of meaning, than with true and false statements.

    Science.gov (United States)

    Müller-Wille, Staffan

    2015-01-01

    The historiography of race is usually framed by two discontinuities: The invention of race by European naturalists and anthropologists, marked by Carl Linnaeus’s Systema naturae (1735); and the demise of racial typologies after WWII in favor of population-based studies of human diversity. This framing serves a similar function as the quotation marks that almost invariably surround the term. “Race” is placed outside of rational discourse as a residue of outdated essentialist and hierarchical thinking. I will throw doubt on this underlying assumption, not in order to re-legitimate race, but in order to understand better why race has been, and continues to be, such a politically powerful and explosive concept.

    An important biological effect of ionizing radiation on living organisms is mutation induction. Mutation is also a primary event in the etiology of cancer. The chain events, from induction of DNA damage by ionizing radiation to processing of these damages by the cellular repair/replication machinery, that lead to mutation are not well understood. The development of quantitative methods for measuring mutation-induction, such as the HPRT system, in cultured mammalian cells has provided an estimate of the mutagenic effects of x- and [gamma]-rays as wen as of high LET radiation in both rodent and human cells. A major conclusion from these mutagenesis data is that high LET radiation induces mutations more efficiently than g-rays. Molecular analysis of mutations induced by sparsely ionizing radiation have detected major structural alterations at the gene level. Our molecular results based on analysis of human HPRT deficient mutants induced by [gamma]-rays, [alpha]-particles and high energy charged particles indicate that higher LET radiation induce more total and large deletion mutations than [gamma]-rays. Utilizing molecular techniques including polymerase chain reaction (PCR), Single-strand conformation polymorphism (SSCP), denaturing gradient gel electrophoresis (DGGE) and Direct DNA sequencing, mutational spectra induced by ionizing radiation have been compared in different cell systems. Attempts have also been made to determine the mutagenic potential and the nature of mutation induced by low dose rate [gamma]-rays. Defective repair, in the form of either a diminished capability for repair or inaccurate repair, can lead to increased risk of heritable mutations from radiation exposure. Therefore, the effects of DNA repair deficiency on the mutation induction in mammalian cells is reviewed.

    2010-01-01

    Full Text Available Husserl - at least in his third intellectual career - was convinced that subject is placed at the heart of philosophy and philosophy is nothing but egology. This Cartesian character makes Husserl one of the greatest figures of modern thought. But in contemporary period, this central ego and, accompanied with that, the modern thought have been challenged by poststructuralists. Because of their focus on psychoanalysis and their priority to other poststructuralist writings, Lacan's argumeats are significant. In this article, at first, we proceed with the Lacan's central idea against the Cartesian subject, and then by explaining Husserl's thoughts we will see what his defence is. Husserl, by phenomenological reduction of natural attitude inherent in natural sciences (among them psychoanalysis, places phenomenology in a different dimension and prefers it to other sciences. The process of raising empirical ego to transcendental ego supports such defence.

    In Belgium, the mutualities are responsible for their budgets. They are playing an important role in drug pricing and reimbursement procedures. This document aims at explaining our line of arguments for a critical evaluation and the place for a pharmacoeconomic evaluation in the Belgian social security system. The available economic data for each molecule or pathology are essential but insufficient. Economic evaluations could help to reveal the costs and benefits of different uses of medical therapies and could thereby enhance the resources allocation in a health care system. But this science is still in its infancy, and in practice, the methodological quality of this kind of study is often weak. Furthermore it is not easy to transfer those evaluations to the Belgian reimburse systems. The clinical efficacy and the transparency is price setting should remain the two most important criterions to build reimbursement rules in order to ensure right price, rational use of medicine and accessibility for all.

    In the proposed accelerator driven systems (ADS) the possible use of several milliamperes of protons of about 1 GeV incident on high mass targets like the molten lead–bismuth eutectic is anticipated to pose radiological problems that have so far not been encountered by the radiation protection community. Spallation reaction products like high energy gammas, neutrons, muons, pions and several radiotoxic nuclides including Po-210 complicate the situation. In the present paper, we discuss radiation safety measures like bulk shielding, containment of radiation leakage through ducts and penetration and induced activity in the structure to protect radiation workers as well as estimation of sky-shine, soil and ground water activation, release of toxic gases to the environment to protect public as per the stipulations of the regulatory authorities. We recommend the application of the probabilistic safety analysis technique by assessing the probability and criticality of different hazard-initiating events using HAZOP and FMECA.

    Today, elevations or sectional views of buildings are often produced from terrestrial laser scanning. However, due to the amount of data to process and because usually 2D maps are required by customers, the 3D point cloud is often degraded into 2D slices. In a sectional view, not only the portions of the objet which are intersected by the cutting plane but also edges and contours of other parts of the object which are visible behind the cutting plane are represented. To avoid the tedious manual drawing, the aim of this work is to propose a semi-automatic approach for creating sectional views by point cloud processing. The extraction of sectional views requires in a first step the segmentation of the point cloud into planar and non-planar entities. Since in cultural heritage buildings, arches, vaults, columns can be found, the position and the direction of the sectional view must be taken into account before contours extraction. Indeed, the edges of surfaces of revolution depend on the chosen view. The developed extraction approach is detailed based on point clouds acquired inside and outside churches. The resulting sectional view has been evaluated in a qualitative and quantitative way by comparing it with a reference sectional view made by hand. A mean deviation of 3 cm between both sections proves that the proposed approach is promising. Regarding the processing time, despite a few manual corrections, it has saved 40% of the time required for manual drawing.

    We study the tagged-particle dynamics by solving equations of the mode-coupling theory (MCT). The numerical solutions are compared with results obtained by the molecular dynamics (MD) simulations from a unified point of view proposed by Tokuyama [Phys. Rev. E 80, 031503 (2009)]. We propose a way of comparison in which the reduced long-time self-diffusion coefficient is used to characterize states of the system. The comparison reveals that the tagged-particle dynamics calculated from MCT qualitatively deviates from that obtained by MD. Our results suggest that the deviation originates from the starting equation of MCT.

    2014-03-01

    Full Text Available In this article, eating behavior is discussed from the point of view of various areas of psychology. First, tasting food and the perception of food palatability are discussed from the viewpoints of sensory and perceptual psychology and of physiological psychology. Second, the phenomenology of some social-psychological effects on eating behavior are introduced – for example, communication at the table, sociocultural variations in food liking/disliking, and emotional changes after eating. Third, these topics are integrated and are applied to food businesses. Two conclusions can be drawn: (1 understanding human eating behavior leads one to understand human beings themselves; (2 a psychological understanding of eating behavior not only gives one broad knowledge of psychology but also provides businesses and governments with hints for improving quality of life.

  5. The Konrad safety case: licensee point of view

    International Nuclear Information System (INIS)

    The protection of man and environment is the most important principle with regard to radioactive waste disposal. This fundamental principle is reflected in the licensing prerequisites for a repository. Since it is intended to dispose of radioactive waste in deep geological formations in the Federal Republic of Germany, possible releases via the water path must be investigated and assessed in particular with regard to the safety of a repository during the post-closure phase. Thus, respective investigations comprise the radiological long-term effects (radionuclide-specific radiation exposures) as well as the possible pollution of near-surface groundwater by organic and inorganic chemo-toxic substances.

    2001-01-01

    The interest in the topic of pain in children is increasing within the paediatric community after a long period of misrecognition, often under-valuation, sometimes negligent or even denial. A lack of knowledge concerning pharmacology and toxicity of antalgic drugs and poorly adapted galenic presentations induced delay and complications in their use in children. The recent progress is supported by a better semiology, development of adequate pain scales, availability of adapted drugs, an effort at education of caregivers and public sensitization. In primary care the objective is to lead the practitioner to identify and consider pain in his/her preventive and curative strategies. In hospitals efforts are needed to improve the use of protocols and evaluations, the systematic practice of preventive analgesia and the quality of interprofessional cooperation within care teams. Managed care organizations are today an effective system to promote these practices.

  7. Pernicious anemia: New insights from a gastroenterological point of view

    2009-01-01

    Pernicious anemia (PA) is a macrocytic anemia that is caused by vitamin B_(12) deficiency, as a result of intrinsic factor deficiency. PA is associated with atrophic body gastritis (ABG), whose diagnosis is based on histological confirmation of gastric body atrophy. Serological markers that suggest oxyntic mucosa damage are increased fasting gastrin and decreased pepsinogen Ⅰ. Without performing Schilling's test,intrinsic factor deficiency may not be proven, and intrinsic factor and parietal cell antibodies are useful surrogate markers of PA, with 73% sensitivity and 100% specificity. PA is mainly considered a disease of the elderly, but younger patients represent about 15% of patients. PA patients may seek medical advice due to symptoms related to anemia, such as weakness and asthenia. Less commonly, the disease is suspected to be caused by dyspepsia. PA is frequently associated with autoimmune thyroid disease (40%) and other autoimmune disorders, such as diabetes mellitus (10%), as part of the autoimmune polyendocrine syndrome. PA is the end-stage of ABG. Longstanding Helicobacter pylori infection probably plays a role in many patients with PA, in whom the active infectious process has been gradually replaced by an autoimmune disease that terminates in a burned-out infection and the irreversible destruction of the gastric body mucosa. Human leucocyte antigen-DR genotypes suggest a role for genetic susceptibility in PA. PA patients should be managed by cobalamin replacement treatment and monitoring for onset of iron deficiency. Moreover, they should be advised about possible gastrointestinal long-term consequences, such as gastric cancer and carcinoids.

    2012-01-01

    This is an entry for the Gallery of Fluid Motion of the 65th Annual Meeting of the APS-DFD (fluid dynamics video). This video shows an analysis of the 'accidental painting' technique developed by D.A. Siqueiros, a famous Mexican muralist. We reproduced the technique that he used: pouring layers of paint of different colors on top of each other. We found that the layers mix, creating aesthetically pleasing patterns, as a result of a Rayleigh-Taylor instability. Due to the pigments used to give paints their color, they can have different densities. When poured on top of each other, if the top layer is denser than the lower one, the viscous gravity current undergoes unstable as it spread radially. We photograph the process and produced slowed-down video to visualize the process.

    Extraterrestrial habitability is a complex notion. We briefly review what is known about the origin of life on Earth, that is, life based on carbon chemistry and water. We then discuss habitable conditions (past and present) for established life and for the survival of microorganisms. Based on these elements, we propose to use the term habitable only for conditions necessary for the origin of life, the proliferation of life, and the survival of life. Not covered by this term would be conditions necessary for prebiotic chemistry and conditions that would allow the recognition of extinct or hibernating life. Finally, we apply this concept to the potential emergence of life on Mars where suitable conditions for life to start, proliferate, and survive have been heterogeneous throughout its history. These considerations have a profound impact on the nature and distribution of eventual traces of martian life, or any precursor, and must therefore inform our search-for-life strategies.

    2011-01-01

    Quantum Information is a new area of research which has been growing rapidly since last decade. This topic is very close to potential applications to the so called Quantum Computer. In our point of view it makes sense to develop a more "dynamical point of view" of this theory. We want to consider the concepts of entropy and pressure for "stationary systems" acting on density matrices which generalize the usual ones in Ergodic Theory (in the sense of the Thermodynamic Formalism of R. Bowen, Y. Sinai and D. Ruelle). We consider the operator $\\mathcal{L}$ acting on density matrices $\\rho\\in \\mathcal{M}_N$ over a finite $N$-dimensional complex Hilbert space $\\mathcal{L}(\\rho):=\\sum_{i=1}^k tr(W_i\\rho W_i^*)V_i\\rho V_i^*,$ where $W_i$ and $V_i$, $i=1,2,...k$ are operators in this Hilbert space. $\\mathcal{L}$ is not a linear operator. In some sense this operator is a version of an Iterated Function System (IFS). Namely, the $V_i\\,(.)\\,V_i^*=:F_i(.)$, $i=1,2,...,k$, play the role of the inverse branches (acting on t...

  11. Communicating radio astronomy with the public: Another point of view

    Radio waves cannot be sensed directly, but they are used in daily life by almost everybody. Even so, the majority of the general public do not even know that celestial bodies emit radio waves. Presenting invisible radiation to a general audience with little or no background knowledge in physics is a difficult task. In addition, much important technology now commonplace in many other scientific fields was pioneered by radio observatories in their efforts to detect and process radio signals from the Universe. Radio astronomy outreach does not have such a well-established background as optical astronomy outreach. In order to make radio astronomy accessible to the public, it is necessary either to add more scientific detail or to find a different way of communicating. In this paper we present examples from our work at the Visitor Centre "Marcello Ceccarelli", which is part of the Medicina Radio Observatory, operated by the Institute of Radio Astronomy (IRA) in Bologna, which in turn is part of the National Institute for Astrophysics (INAF).

  12. Friction in macroscopic thermodynamics: A kinetic point of view

    Science.gov (United States)

    Bizarro, João P. S.

    2015-12-01

    To provide a solid support to a macroscopic framework developed to explicitly account for friction in thermodynamics, a kinetic description of frictional dissipation is developed. Using either a dissipative Fokker-Planck equation for Brownian motion or a Boltzmann equation with a friction-force term added, it is shown that both approaches lead to the emergence of the macroscopic thermodynamic relations that state the first and second laws with friction. The analysis is directly applied to the problem of determining the minimum amount of heating generated by memory erasure, known in computer science as Landauer's bound, and leads to a better understanding of the energetics behind the latter. A generalisation of Boltzmann's H theorem to include friction explicitly is also recovered, and the thermodynamics of granular rotators acted by a frictional torque and of radio-frequency (RF) current drive of fusion plasmas, in which collisional drag is present, are addressed as well. Various physics results are revisited employing the first and second laws with friction that have been derived from the appropriate dissipative kinetic equations, lower bounds for entropy production rates being derived both for granular rotators and for RF current drive.

    The nuclear matrix is defined as the residual framework after the removal of the nuclear envelope, chromatin, and soluble components by sequential extractions. According to several investigators the nuclear matrix provides the structural basis for intranuclear order. However, the existence itself and the nature of this structure is still uncertain. Although the techniques used for the visualization of the nuclear matrix have improved over the years, it is still unclear to what extent the isolated nuclear matrix corresponds to an in vivo existing structure. Therefore, considerable skepticism continues to surround the nuclear matrix fraction as an accurate representation of the situation in living cells. Here, we summarize the experimental evidence in favor of, or against, the presence of a diffuse nucleoskeleton as a facilitating organizational nonchromatin structure of the nucleus.

    Full Text Available A lot of people live situations of mental sickness, from psychotic character, that can cause sufferingboth for the sick and his family. We believe that try this situation means to live with limitations and wearings in thefamiliar everyday, what makes difficult the living with the psychotic person. Considering these aspects, thisresearch has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It isabout a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state,called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapygroup in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all.The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the containedinformation in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. Onfirst thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in themoment he has the acute symptoms. On the second thematic, we talked about the medical question as bring atherapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematicshows the family conception about mental sickness. With this research we concluded that the living with a mentalsick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed bythe sick person. Besides that, the family considers the medication one of the most important possibilities ofintervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

  15. Test and acceptance from the AE point of view

    International Nuclear Information System (INIS)

    The power industry has undergone the transition from utilizing construction engineers for startup activities to utilizing test engineers who are responsible for the preparation or execution of a formal test program. This has come about because testing has been given sufficient importance to justify those participating within the industry to establish it as a specialty phase apart from engineering/design and construction. Presently testing is being conducted by those organizations that have either engineered and/or constructed the unit which may be a position of conflict in regards to unbiased test. The tester (third party) concept promotes the repetition, independence, and expertise of a test organization responsible to the utility for certifying that each system has been tested to the design criteria established by others. A move to this concept should result in better generating stations with higher availability because it has been completely tested by an organization with this sole contractual responsibility. The AE, NSSS, and utility would all benefit with possibly no additional costs incurred

  16. Moral Luck from Bernard Williams’ Point of View

    2016-08-01

    Full Text Available Moral luck is an important issue in meta- ethics. Its conflict to principle of control make challenges to moral moral assessment, moral judgment and moral responsibility. Bernard Williams is the first philosopher who uses the expression "moral luck" and tries to show that the contradiction between “moral” and “luck” is not so serious. Against Kantian’s idea and also our intuitions Williams doesn’t believe that morality is immune of luck and that unlike other values, is accessible to all people. If moral value is accessible to all, according to his idea, it should be not only immune of luck but also supreme. Giving some examples, Williams by concepts like justification, regret and retrospective, shows that morality hasn’t these characteristics. Dividing moral luck into four types: resultant, circumstantial, constitutive and causal, Thomas Nagel puts Williams' moral luck under the first type and criticizes it. This study seeks to explain Bernard Williams’ viewpoint on moral luck. At first it clears types of moral luck, principle of control and its contradiction with moral luck, then after explaining Williams’ account of moral luck criticizes it. Nagel’s criticisms and others show that although they accept the existence of moral luck and also their account is compatible to williams’ but they deny williams’ success in defending of this phenomenon. Finally, despite of all critiques, it seems that Williams’ failure in defense of moral luck didn’t decrease the importance of this matter, but made some stronger ideas were appeared by Thomas Nagel in this regard.

    We have investigated ten standard single crystal substrates of complex oxides on the account of their applicability in the Raman spectroscopy based thin film research. In this study we suggest a spectra normalization procedure that utilises a comparison of the substrate's Raman spectra to those of well-established Raman reference materials. We demonstrate that MgO, LaGaO3, (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT), DyScO3, YAlO3, and LaAlO3 can be of potential use for a Raman based thin film research. At the same time TiO2 (rutile), NdGaO3, SrLaAlO4, and SrTiO3 single crystals exhibit multiple phonon modes accompanied by strong Raman background that substantially hinder the Raman based thin film experiments.

    The rational construction of an essential drug list, considering the patient's need, drug safety, availability and the best cost-benefit ratio, is based on drug safety, efficacy and quality. However, in daily practice, the prescriber's decision is mostly influenced by drug effectiveness, following criteria that increase adherence to the treatment, such as relative drug toxicity, convenience, cost and prescriber's experience. In addition, frequent launching of new molecules for the same therapeutic indication, together with wide publicity targeting prescribers, interferes with the decision-making process. Similarly, the bonuses offered by the industry for over-the-counter drug sales interfere with the consumer's choice. The confrontation between known human biological variability and the knowledge that there is no absolute similarity between drugs of the same therapeutic class, or even generic drugs, has an impact on the prescriber's drug list, which should include the concept of first and second choice drugs. Prescribers' unfamiliarity with these subjects is a determinant factor for irrational drug use: a public health issue. The objective of this study was to introduce to drug prescribers information that can help them building up a rational drug list for their patients, based on the National Health Surveillance Agency (Anvisa) experience of drug regulation.

    International Nuclear Information System (INIS)

    Westinghouse Atom is situated in Vasteras approximately 100 km west from Stockholm. The company is owned by BNFL. The two largest divisions are the Nuclear Fuel Operations and The Global Reactor Services division. The Nuclear fuel operations manufacture fuel for BWR and PWR reactors. The raw material used is Uranium hexafluoride, which is converted to Uranium dioxide powder through wet AUC-process. The concession is 600 tonnes of UO2, per year. Last year the production. was approximately 900 fuel elements. There is also a control rod production line within the fuel factory. Last year the production of control rods was approximately 160. The Global Reactor Services Division performs tests on different types of equipments used in nuclear power plants. In addition there is also a well-established service structure that provides a wide range of field services, for instance sipping of fuel elements. The total amount of people working in Vasteras is currently around 800. The majority of those, work at the fuel factory. The purpose of this paper is to describe the somewhat awkward situation for our employees when working as external personnel on German nuclear installations. Our Swedish personnel are currently using German dose passports. Since Sweden joined the European Union in 1995 this is in contradiction to the EU-directives. Hence, Westinghouse Atom has applied for a license for the use of Swedish dose passports in Germany. The amount of people performing service jobs in Germany is approximately 80 persons. (authors)

    AIM: Gastrointestinal autonomic nerve tumors are uncommon stromal tumors of the intestinal tract. Their histological appearance is similar to that of other gastrointestinal stromal tumors. We report two cases and performed an analysis of the literature by comparing our findings with the available case reports in the medical literature.METHODS: Two patients were admitted with abdominal tumor masses. One occurred in the stomach with large multiple liver metastases and the second originated in Meckel's diverticulum. The latter site has never been reported previously. Both patients underwent surgery. In one patient gastrectomy, right liver resection and colon transversum resection were performed to achieve aggressive tumor debulking. In the other patient the tumor bearing diverticulum was removed.RESULTS: Postoperative recovery of both patients was uneventful. Histological examination, immunohistochemical analysis and electron microscopy revealed the diagnosis of a gastrointestinal autonomic nerve tumor. The patient with the tumor in Meckel's diverticulum died 6 mo after surgery because of pneumonia. The patient with liver metastases have been alive 13 years after initial tumor diagnosis and 7 years after surgery with no evidence of tumor progression. In light of our results, we performed a thorough comparison with available literature reports.CONCLUSION: Radical surgical resection of gastrointestinal autonomic nerve tumors seems to be the only available curative approach to date, and long term survival is possible even in large metastasized tumors.ACKNOWLEDGMENTWe thank Christine Brostjan, PhD for critical review of the manuscript.

  1. Multi-View Point Clouds Registration without Feature Extraction for Use in Reverse Engineering of CAD Models

    Institute of Scientific and Technical Information of China (English)

    Huang Xiaoping; Xiong Youlun

    2001-01-01

    For reverse engineering a CAD model, it is necessary to integrate measured points from several views of an object into a common reference frame. Given a rough initial alignment of point cloud in different views with point-normal method, further refinement is achieved by using an improved iterative closest point (ICP) algorithm. Compared with other methods used for multi-view registration, this approach is automatic because no geometric feature, such as line, plane or sphere needs to be extracted from the original point cloud manually. A good initial alignment can be acquired automatically and the registration accuracy and efficiency is proven better than the normal point-point ICP algorithm both experimentally and theoretically.

    2014-01-01

    Esophageal cancer treatment has evolved from single modality to trimodality therapy.There are some controversies of the role,target volumes and dose of radiotherapy(RT)in the literature over decades.The present review focuses primarily on RT as part of the treatment modalities,and highlight on the RT volume and its dose in the management of esophageal cancer.The randomized adjuvant chemoradiation(CRT)trial,intergroup trial(INT 0116)enrolled 559 patients with resected adenocarcinoma of the stomach or gastroesophageal junction.They were randomly assigned to surgery plus postoperative CRT or surgery alone.Analyses show robust treatment benefit of adjuvant CRT in most subsets for postoperative CRT.The Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study(CROSS)used a lower RT dose of41.4 Gray in 23 fractions with newer chemotherapeutic agents carboplatin and paclitaxel to achieve an excellent result.Target volume of external beam radiation therapy and its coverage have been in debate for years among radiation oncologists.Pre-operative and postoperative target volumes are designed to optimize for disease control.Esophageal brachytherapy is effective in the palliation of dysphagia,but should not be given concomitantly with chemotherapy or external beam RT.The role of brachytherapy in multimodality management requires further investigation.On-going studies of multidisciplinary treatment in locally advanced cancer include:ZTOG1201 trial(a phaseⅡtrial of neoadjuvant and adjuvant CRT)and QUINTETT(a phaseⅢtrial of neoadjuvant vs adjuvant therapy with quality of life analysis).These trials hopefully will shed more light on the future management of esophageal cancer.

  4. Main post-accident management stakes: IRSN's point of view

    International Nuclear Information System (INIS)

    Full text of publication follows: Off site management of a radiological crisis covers two phases which need to be clearly distinguished even if there are links between them: emergency phase and recovery phase (also called late or post-accident phase). The presentation will deal with the latter, rather neglected up until recently, but conveying special attention from now on in France and at the international level. It is clear now that the long term management of a radiological or nuclear crisis cannot be reduced to merely site decontamination. Actually, environmental decontamination considerations would be only one amongst other essential economical, social, health, psychological, cultural, and symbolical concerns. This is why off site management of a radiological crisis requires innovative governance, in order to challenge such a complexity. This need for challenge led IRSN to have on the go technical developments and new governance modes reflection. 1) Technical developments: they deal with implementing an organisation, a set of methods, a platform of technical tools which would allow the stakeholders to carry out efficiently their mission during the recovery phase. For example, countermeasures for agricultural and urban rehabilitation are developed within the framework of the 6. PCRDT EURANOS programme. Teams from several countries are involved in common elaboration of rehabilitation strategies based on the best available knowledge. Besides this, simple operational decision aiding tools for the stakeholders (local administration, elected representatives, professional agricultural groups, etc.) are currently developed by IRSN within the framework of the nuclear post-accident exercises. IRSN is also involved in doctrinal reflections about the respective roles of radioactive measurements in the environment and radiological consequences calculation during emergency and recovery phases. Criteria for emergency countermeasures withdrawal are also currently under

  6. $QCD_{4}$ From a Five-Dimensional Point of View

    CERN Document Server

    Baulieu, L; Baulieu, Laurent; Zwanziger, Daniel

    2000-01-01

    We propose a 5-dimensional definition for the physical 4D-Yang-Mills theory. The fifth dimension corresponds to the Monte-Carlo time of numerical simulations of QCD_4. The 5-dimensional theory is a well-defined topological quantum field theory that can be renormalized at any given finite order of perturbation theory. The relation to non-perturbative physics is obtained by expressing the theory on a lattice, a la Wilson. The new fields that must be introduced in the context of a topological Yang-Mills theory have a simple lattice expression. We present a 5-dimensional critical limit for physical correlation functions and for dynamical auto-correlations, which allows new Monte-Carlo algorithm based on the time-step in lattice units given by $\\e = g_0^{-13/11}$ in pure gluodynamics. The gauge-fixing in five dimensions is such that no Gribov ambiguity occurs. The weight is strictly positive, because all ghost fields have parabolic propagators and yield trivial determinants. We indicate how our 5-dimensional descr...

    2011-11-01

    Candidiasis is the fourth most common bloodstream infection in hospitalized patients in the United States. Moreover, the mortality rate from Candida infections remains high, even after treatment with antifungal therapy. Vaccination would be a promising strategy for prevention of invasive fungal infections. In order to examine the main trends in anticandidal vaccine patenting activity, we conducted an analysis for anticandidal vaccine patents. We find 190 issued patent and 940 patent application documents containing the keywords Candida and vaccine within claims in the USA. Candida vaccines development, as evidenced by the numbers of issued patents, has decreased since the year 2002. Furthermore, the number of patent applications in Candida vaccines may indicate the strength of engaged resources were also in the status of stagnation during 2005-2007 and even a decline in 2008. Academic and nonprofit research institutions not only account for a large share of Candida vaccines patents but also apply for patents continually. Based on this analysis, the strength of Candida vaccines resources seems to remain stagnant in recent years due to patent prosecution or technical barrier in the filed of Candida vaccines. Therefore, we consider that Candida vaccines technology to still be under development and the researchers are still looking for scientific breakthrough in the filed. PMID:22048114

    Full Text Available In this study, solar absorptance of external surfaces of buildings has been numerically investigated from the heat gain and losses point of view. For this purpose, external surface solar absorptance was icreased from 0 to 1with an ratio of 0.1 and, for the summer and winter conditions, heat fluxs was calculated by considering orientations of the wall and its roof for brick and concrete structure materials. Besides, external surface absorptance was assumed as 0.2, 0.5 and 0.9, respectively. Than, heat gain and losses were calculated to insulation thickness increasing on the outdoor surface of wall. Results obtained were presented as graphics

    During the Miocene-Pliocene the Mediterranean region experienced major changes in paleogeography. Today, its only connection to the global ocean is the Strait of Gibraltar. This restricted nature causes the Mediterranean basin to react more sensitive to climatic and tectonic related phenomena than the global ocean: Not just eustatic sea-level and regional river run-off, but also gateway tectonics and connectivity between sub-basins are leaving an enhanced fingerprint in its geological record. To understand its evolution, it is crucial to understand how these different effects are coupled. The Miocene-Pliocene sedimentary record of the Mediterranean alternates in composition and colour. Around the Miocene-Pliocene Boundary the most extreme changes occur in the Mediterranean Sea: About 6% of the salt in the global ocean got deposited in the Mediterranean Region, forming an approximately 2km thick salt layer, which is still present today. This extreme event is named the Messinian Salinity Crisis (MSC, 5.97-5.33Ma). Before (and also after) the MSC, the sedimentary record demonstrates "marl dominated" alternations with variations in organic content (e.g. higher organic content = sapropel). During the MSC these change to mainly "evaporite (e.g. gypsum or halite) dominated" alternations, but also to brackish Black Sea-type of deposits towards the end of the crisis. Due to its relative short geological time span, the period before, during and after the MSC is ideal to study these extreme changes in sedimentation. We are investigating these couplings and evolutions in a box/budget model. With such a model we can study the responses to basin water exchange dynamics under the effect of different regional and global climatic and tectonic forcings, to predict the evolution of basin properties (e.g. salinity). By doing so we can isolate certain climatic and tectonic effects, to better understand their individual contribution, their interaction, but also the consequences due to

  11. Spatial orientation of cross-sectional images of coronary arteries: point of view in intracoronary imaging

    2012-03-01

    Full Text Available Abstract Background In studies where cross-sectional images of coronary arteries obtained with different imaging modalities are compared, the importance of correct co-localization and matching of images along the coronary artery longitudinal axis is obvious. However, it appears neglected that correct spatial orientation of the cross-sectional plane may not be obtainable just by rotating the images to ensure co-localization of identifiable landmarks such as sidebranches. A cross-section has two sides, one facing proximally and the other distally, and pairs of images reconstructed corresponding to these opposite points of view are mirror images of each other and not superimposable. This may be difficult if not impossible to recognize and unrecognized it will give rise to flawed results in the development and validation of imaging technologies aimed at plaque characterization (tissue mapping. We determined the imagined point of view for three commercially available intracoronary imaging systems used by invasive cardiologists and illustrate its importance in imaging modality validation. Methods and Results We made an asymmetric phantom and investigated it with two different intravascular ultrasound (IVUS systems and one optical coherence tomography (OCT system. The asymmetry of the phantom allowed determination of the spatial orientation of the cross-sectional images. On all tested systems, an observer should imagine herself/himself standing proximal to the cross-section when looking at the intravascular images. Conclusions The tested intracoronary imaging modalities displayed cross-sectional images with a spatial orientation corresponding to a proximal point of view. Knowledge of the spatial orientation is mandatory when comparing and validating different imaging modalities aimed at plaque characterization.

    Full Text Available Nowadays it is vital to stay informed. But why is the information so important? The following will present the role and the importance of accounting information in decision-making regarding economic entity. Is accounting information a want or a need? Can accounting information be interpreted correctly indifferent of the accounting model used? Decisions made by the consumers of accounting information would be the same in terms of using the "cash" or "accrual" method? Based on these questions, this paper presents data as a whole for everyone and from where each consumer of information can extract only the part that they are interested in and which is useful for them. This paper follows the interests of users of accounting information regarding the interest, the need for information and the decisions they may take as a result of the information received, and also of the accounting model used by the entity from which the information is expected. This paper does not include all users of the accounting information that have interest in the economic entity, nor does it take into account all the information that are affected by the use of a model of accounting or the other one of the economic entity, but we can conclude that there are situations in which users ' decisions are influenced by the accounting model used, and others where there is no influence. We can't rule on any model to be the best; it is good that provides useful information showing the true reality of the economic entity.

    2015-06-01

    Full Text Available The current situation of the environment is a direct consequence of history, especially of economic history. The article analyzes the relationship between economy and environment, in order to determine the main causes that led to the ecological crisis. The article argues that despite the close relationship between environment and economy, the economy did not take into account the environmental protection, until there appeared serious environmental impacts. Including the environment in economic thinking led, first, to the application of conventional techniques to economy to try to solve problems. The article also examines some priorities for improving the relationship between economy and environment conducive to move towards a model of sustainable development. The conclusion is that sustainable development is the goal to be achieved. In search of sustainability, companies should play an important role, as in all phases of the life cycle of their products, there are environmental risks and, therefore, they are a major source of environmental degradation of the planet.

    2016-04-01

    The historical allure of epilepsy transcends academic circles and serves as fascinating critique of the state of the times-its values, judgments, mythos, and people. Immortalized and laid bare in artistic renderings of epilepsy are societal truths, at times both disparately grandiose and grotesque. During the middle ages and Renaissance, the European discourse on epilepsy assumed religious fervor. Epilepsy was considered a demonic machination and its cure an act of divine intercession. A similar theme is found in the artistic depiction of epilepsy from the Inca and Aztec civilizations of that time. After the 19th century drew to a close, the ascendency of empiricism coincided with waning creative interest in epilepsy, with few paintings or pieces to capture insightful perspectives on the illness. In this paper, we review the relationship between art and epilepsy and present two contemporary paintings that convey current western perceptions. This article is part of a Special Issue entitled "Epilepsy, Art, and Creativity". PMID:26874992

  20. [Collective versus selective contracts from a legal point of view].

    Science.gov (United States)

    Schirmer, Horst Dieter

    2006-01-01

    The historically proven organisational model of service relations between sickness funds and healthcare providers are collective contracts. A collective contract as a standards treaty ("Normenvertrag") is particularly pronounced concerning the panel doctor law ("Vertragsarztrecht") defining medical care on the basis of the principle of benefits in kind governing benefit claims of the insured in case of illness. The collective contract is a suitable instrument for ensuring both consistent and exhaustive provision of care and for organising the conditions of care, especially the quality and reimbursement of professional medical services. For several years the legislator has been "experimenting" with parallel contract design patterns such as the contract of integrated care in the form of selective contracts between health insurances or their associations and healthcare providers or groups of healthcare providers. More recently, allowances for conclusion of such contracts have been supposed to lead to competition between the contractual systems. It is doubtful whether this "push-start" will contribute to overcoming the systematic legal disadvantages of selective contracting as an organisational model for the provision of healthcare services to the insured.

  1. Plant Sucrose Transporters from a Biophysical Point of View

    2011-01-01

    T The majority of higher plants use sucrose as their main mobile carbohydrate. Proton-driven sucrose transporters play a crucial role in cell-to-cell and long-distance distribution of sucrose throughout the plant. A very negative plant membrane potential and the ability of sucrose transporters to accumulate sucrose concentrations of more than 1 M indicate that plants evolved transporters with unique structural and functional features. The knowledge about the transport mechanism and structural/functional domains of these nano-machines is, however, still fragmentary. In this review,the current knowledge about the biophysical properties of plant sucrose transporters is summarized and discussed.

  5. Pre-irradiation from the surgeon's point of view

    International Nuclear Information System (INIS)

    If we compare the possibilities of radiotherapy to the causes of surgical failure we see that, provided a tolerable side effect rate, both disciplines complete each other in a natural way. I tried to show that increasing the efficiency of surgical measures can be expected especially from pre-irradiation. This partnership can be expressed in a simple equation: the kinetic part of the therapy, radiation treatment, fights against tumour kinetics, its expansion; while the mechanical part, the operation, eliminates the static, i.e. the radiation-resistent tumour nucleus. On the other side of this equation, increased healing and more qualitative life prolongation should appear. (orig.)

    2005-04-01

    Organ transplantation has been transformed from an experimental procedure at Western academic centers to an increasingly common procedure in private and public hospitals throughout the world. Attendant with advancements in organ harvesting, preservation, and transplantation come moral issues. Islam is a holistic religion that takes into account social affairs of man as well as spiritual ones. Islam has a long history of ethics literature including the subgenre of medical ethics. Historical considerations are discussed as to why Muslim thinkers were late to consider contemporary medical issues such as organ donation. Islam respects life and values the needs of the living over the dead, thus allowing organ donation to be considered in certain circumstances. The sources of Islamic law are discussed in brief in order for non-Muslims to appreciate how the parameters of organ transplantation are derived. The Islamic viewpoint, both Shiite and Sunni, is examined in relation to organ donation and its various sources. The advantages and disadvantages of brain dead and cadaveric donation is reviewed with technical and ethical considerations. The Islamic concept of brain death, informed and proxy consent are also discussed. We discuss the concept of rewarded donation as a way to alleviate the current shortage of organs available for transplantation and consider secular and religious support for such a program. Suggestions are made for greater discussion and exchange of ideas between secular and religious thinkers in the Islamic world and between the Islamic world and secular Western countries.

    The theory of investment portfolios is a well defined component of financial science. While sound in principle, it faces some setbacks in its real-world implementation. In this paper the authors propose a reformulation of the investment portfolio problem as a cybernetic system where the Investor is the controlling system and the portfolio is the controlled system. Also the portfolio controlling process should be dissected in several ordered phases, so that each phase is represented as a subsystem within the structure of the controlling system Investor.

  19. The Konrad safety case: regulator point of view

    International Nuclear Information System (INIS)

    On 22 May 2002 the plan approval (i.e. licensing) decision for the KONRAD repository (located near Salzgitter in Lower Saxony, Germany) for the disposal of radioactive waste with negligible heat generation was assigned after almost 20 year duration of the licensing procedure. According to the German regulations, the only quantitative radiological criterion for the long-term safety assessment is the limit for the individual dose, e.g. 0.3 mSv/y effective dose. An additional criterion was the limitation of chemo-toxical components in groundwater given in the 'regulations for drinking water' in Lower Saxony. The licensing authority required the limitations of radioactive dose and chemo-toxical elements to be used as assessment criterion over the whole calculated time span until reaching the concentration maximum of the radionuclides, i.e. up to some 100 000 or even to 1000 000 years.

    CERN Document Server

    Hatano, Takahiro

    2015-01-01

    Friction laws, which are a key to the understanding of the diversity of earthquakes, are considered theoretically. Using dimensional analysis, the logarithmic dependence of the friction coefficient on the slip velocity and the state variable is derived without any knowledge of the underlying physical processes on the frictional surface. This is based on a simple assumption that the friction coefficient is expressed as the difference from a reference state. Therefore, the functional form of the rate and state dependent friction law itself does not necessarily mean that thermal activation processes dominate friction. It is also shown that, if there are two (or more) state variables having the same dimension, we need not assume the logarithmic dependence on the state variables.

    2010-01-01

    Gowers norms have been studied extensively both in the direct sense, starting with a function and understanding the associated norm, and in the inverse sense, starting with the norm and deducing properties of the function. Instead of focusing on the norms themselves, we study associated dual norms and dual functions. Combining this study with a variant of the Szemeredi Regularity Lemma, we give a decomposition theorem for dual functions, linking the dual norms to classical norms and indicating that the dual norm is easier to understand than the norm itself. Using the dual functions, we introduce higher order algebras that are analogs of the classical Fourier algebra, which in turn can be used to further characterize the dual functions.

    @@ Most organic materials for optoelectronic applications are conjugated organic system. The burgeoning synthetic methodologies using organometallic catalysts or reagents have provided a powerful arsenal to design and synthesize new conjugated organic materials. It is particularly noteworthy that carbon-carbon bond formation involving a Csp2 or Csp at the reaction center can readily be achieved. For examples, cross-coupling reactions (e.g. Kumada-Corriu reaction, Stille reaction, and Suzuki reaction) are extremely powerful for the synthesis of Csp2-Csp2 single bond. Sonogashira reaction, on the other hand, serves as a useful entry for the preparation of alkynylarenes or conjugated enynes. Heck reaction furnishes a coupling between an aryl halide and an alkene. Alternatively, olefination reactions provides a practical route for the synthesis of carbon-carbon double bond. In the past decade, we have uncovered four new kinds of transformations staring from the dithioacetal functionality (Scheme).1,2 Three of them have been employed in the synthesis of conjugated small molecules as well as conjugated oligomers/polymers. Their syntheses, photophysical as well as electroluminescent properties will briefly be discussed.

    Converging experimental evidence indicates that mirror neurons in the monkey premotor area F5 encode the goals of observed motor acts [1-3]. However, it is unknown whether they also contribute to encoding the perspective from which the motor acts of others are seen. In order to address this issue, we recorded the visual responses of mirror neurons of monkey area F5 by using a novel experimental paradigm based on the presentation of movies showing grasping motor acts from different visual perspectives. We found that the majority of the tested mirror neurons (74%) exhibited view-dependent activity with responses tuned to specific points of view. A minority of the tested mirror neurons (26%) exhibited view-independent responses. We conclude that view-independent mirror neurons encode action goals irrespective of the details of the observed motor acts, whereas the view-dependent ones might either form an intermediate step in the formation of view independence or contribute to a modulation of view-dependent representations in higher-level visual areas, potentially linking the goals of observed motor acts with their pictorial aspects.

    Defining Issue According to the statistics presented by the Ministry of Emergencies of Ukraine, river floods have imposed the most severe damages to the sectors of economy and the human communities in Ukraine. But, an adaptability and a vulnerability of Ukrainian society to floods are still poorly understood. Results Presentation In the response to increasing flood losses in the country between 1998 and 2008, the State Hydrometeorological Service of Ukraine, which is subordinate to the Ministry of Emergencies, in the cooperation with the National Academy of Sciences of Ukraine have carried out the research study focusing on public views on the problem of river floods for Ukraine. Aims of this study were: a) exploring the main sources of information on water-related hazards and the level of knowledge useful in a flood crisis situation in different groups of peoples; b) learning what the various population groups think of the most significant causes and consequences of flood damages and the role of various central/governmental/ and local authorities in an elaboration and implementation of mitigation measures. Public attitudes towards various prevention and mitigation strategies, as well as sources of emerging conflict were also revealed. The results of study have given a possibility to compare points of view of population groups which: a) living in the low- and high- flood risk areas; b) living in the urban and rural areas; c) having the different levels of education. The responses from 2550 residents have been analyzed and summarized. Among the most important findings of this study can be indicated following: a) on the one hand, the level of knowledge of some aspects of flood problem (impact of climate variation and change, adaptation measures) of the general public should be improved, on the other hand, the most of peoples understand that floods are the significant economical and ecological problem; b) views of the public on the problem differ very much with regard

  11. Some Considerations on Six Degrees of Separation from A Theoretical Point of View

    CERN Document Server

    Toyota, Norihito

    2008-01-01

    In this article we discuss six degrees of separation, which has been proposed by Milgram, from a theoretical point of view. Simply if one has $k$ friends, the number $N$ of indirect friends goes up to $\\sim k^d$ in $d$ degrees of separation. So it would easily come up to population of whole world. That, however, is unacceptable. Mainly because of nonzero clustering coefficient $C$, $N$ does not become $\\sim k^d$. In this article, we first discuss relations between six degrees of separation and the clustering coefficient in the small world network proposed by Watt and Strogatz\\cite{Watt1},\\cite{Watt2}. Especially, conditions that $(N)>$ (population of U.S.A or of the whole world) arises in the WS model is explored by theoretical and numerical points of view. Secondly we introduce an index that represents velocity of propagation to the number of friends and obtain an analytical formula for it as a function of $C$, $K$, which is an average degree over all nodes, and some parameter $P$ concerned with network topo...

    The authors present an abridged history from their personal point of view of public health dealing with communicable diseases in Chile, in reference to an article previously published in Revista Chilena de Infectología. They do not agree with the mainly critical view of the author. They recognize that although there is a lot to be done on this matter, Chile has been a pioneer in Latin America in many policies relating to the control of these infections, having been recognized by international organisms. The relationship between the National Institute of Public Health, the Ministry of Health and the Laboratory Network, has strongly contributed along the years to concrete sanitary achievements in the field of transmissible diseases which are a pride for our country.

  13. Participation of the national industry within a nuclear power plant program by technology transfer from the point of view of the main contractor

    International Nuclear Information System (INIS)

    The broad scope of components needed in a nuclear power plant with various technical requirements offer a big opportunity for the participation of local industries in the construction of such plants. Depending on the existing capability of the industrial enterprises, the scope of national participation can be increased by technology transfer on all technical areas to be applied for the construction of NPPs. Such technology requires as basis a nuclear program of the country determined and supported by the government and the utilities. This program has to be defined as realistic as even possible adjoined to the future energy demand of the country. Furthermore the available capability, existing qualifications and equipment of the national industry have to be considered. On the basis of these fundamental requirements a tailormade technology transfer program has to be elaborated in close cooperation with an experienced main contractor of the plant and his partners for such technology transfer and should be established afterwards. This program has to consider not only the goal to achieve finally the independent production of components and equipment for NPPs or the construction of complete power plant units itself, but also the economic benefit of such a program for the country. The costs of technology transfer and the necessary investment of the national industry required for the manufacture of nuclear components have to be thoroughly investigated, based on the expected scope of products to be manufactured for the nuclear power plants according to the nuclear program. Furthermore the application of the technology transferred for other components e.g. for conventional power stations, mineral-oil or chemical industrial plants has to be considered. By a tailormade nuclear technology transfer program, executed by qualified and experienced partners not only the quality of the products of the national industry for NPPs will be improved, but also the general standard regarding

  18. A novel point of view on the conformal anomaly for quantised Dirac fields

    International Nuclear Information System (INIS)

    One of the main and many lessons we learned from the study of scalar fields on globally hyperbolic backgrounds, is that we can account for the so-called quantum trace anomaly employing a modified version of the classical stress-energy tensor as well as a point-splitting regularization by means of an Hadamard bidistribution. In this talk we show that such approach can be traded to Dirac fields yielding a similar result. Particularly we shall try to emphasize, that, although we are reproducing already known results, this point of view is, on the one hand, conceptually rigorous and clear while, on the other hand, it opens the road to possible applications in a cosmological scenario

    2014-05-01

    Full Text Available This exploratory research focuses on the retention of highly skilled workers in science and technology (HSWST in the distant regions of Canada.  Indeed, the human resource shortage forces them to seek more stability in their employment relationships. Our first objective is to analyze the point of view of distant regional employers regarding their retention capacity of HSWST and the reasons behind voluntary turnover in this group of workers. Our second objective is to analyze the retention strategies and practices implemented by these employers. This study uses a qualitative approach, which is to say the case study of businesses hiring HSWST in the Lower St. Lawrence Region of Canada. Results show that employers generally think they have good retention capacity. Employers believe that departures are chiefly due to personal reasons or working conditions. In addition, employers generally have no formal or planned strategies or practices with respect to retention.

  7. Benefit assessment of PET in malignant lymphomas. The IQWiG point of view

    International Nuclear Information System (INIS)

    The call by the Institute for Quality and Efficiency in Health Care (IQWiG) for randomised controlled trials (RCTs) to prove the patient-relevant benefit of positron emission tomography (PET) is currently a controversial topic in Germany. From a methodological point of view there is essentially no difference between diagnostic procedures and therapeutic (drug or non-drug) interventions in proving their causal benefit. A broad consensus has been reached since the 1960s (e.g. FDA regulations) that RCTs are the methodological gold standard for therapeutic interventions. Nevertheless, the same arguments that were cited against RCTs in assessing the benefit of therapeutic interventions are now used against RCTs in evaluating diagnostic tests (e.g. ethical problems, feasibility, etc.). This paper summarizes the central methodological arguments of the discussion on the benefit assessment of PET in malignant lymphomas from the perspective of IQWiG and its external experts. (orig.)

    2013-04-01

    Over the last 4 decades innovations in biomaterials and medical technology have had a sustainable impact on the development of biopolymers, titanium/stainless steel and ceramics utilized in medical devices and implants. This progress was primarily driven by issues of biocompatibility and demands for enhanced mechanical performance of permanent and non-permanent implants as well as medical devices and artificial organs. In the 21st century, the biomaterials community aims to develop advanced medical devices and implants, to establish techniques to meet these requirements, and to facilitate the treatment of older as well as younger patient cohorts. The major advances in the last 10 years from a cellular and molecular knowledge point of view provided the scientific foundation for the development of third-generation biomaterials. With the introduction of new concepts in molecular biology in the 2000s and specifically advances in genomics and proteomics, a differentiated understanding of biocompatibility slowly evolved. These cell biological discoveries significantly affected the way of biomaterials design and use. At the same time both clinical demands and patient expectations continued to grow. Therefore, the development of cutting-edge treatment strategies that alleviate or at least delay the need of implants could open up new vistas. This represents the main challenge for the biomaterials community in the 21st century. As a result, the present decade has seen the emergence of the fourth generation of biomaterials, the so-called smart or biomimetic materials. A key challenge in designing smart biomaterials is to capture the degree of complexity needed to mimic the extracellular matrix (ECM) of natural tissue. We are still a long way from recreating the molecular architecture of the ECM one to one and the dynamic mechanisms by which information is revealed in the ECM proteins in response to challenges within the host environment.

    Koeser, H.; Rozycki, C. v.; Taplick, R. [Univ. Halle-Wittenberg (Germany). FB Verfahrenstechnik

    1998-07-01

    A review is given on the state of the methodology and the application of life cycle assessment from the point of view of industrial environmental protection. After defining the most common terms the more recent development of the international standardisation activities in this area is reviewed. The life cycle assessments finished in Germany so far are evaluated according to subject and orderer. In an industrial setting life cycle assessment is very often used together with accumulated energy demand, environmental auditing and environmental reporting. The common ground and the differences of this four methods are discussed. It is shown that the site ecobalance, that is the life cycle assessment of a production site, provides a range of quantitative information for the environmental management decision process. Legal documentation duties are supported, environmental performance indicators of different activities on the site are evaluated and early warning indicators for potential operational disturbances are given, to name a few insights coming from site ecobalance data. Site ecobalances have to be computer supported and integrated with the other information systems of a company. In this area the ongoing development work on practical and methodological aspects is likely to result in the foreseeable future in the site ecobalances being a central instrument for ecological planning, controlling and supervision in industrial environmental management.

    1999-12-01

    Parental presence in the dental operatory is considered a controversial issue and majority of dentists prefer mothers not to be present in the operatory while the child receives dental care. Very few studies have focussed on the parental' point of view. The present study was carried out to find out the attitudes of parents towards being present determine in the operatory during dental procedure and also to determine if willingness to be present was influenced by variables like age, sex, order of the child among siblings and previous dental behavior. Data was collected from 1350 parents using a questionnaire designed by the authors. In the present study, 78.3% of parents expressed their willingness to be present with the child during dental procedures. The study also showed that parents of younger children were more likely to be willing to be present in the operatory and as age advanced, the percentage of parents willing to be present in the operatory decreased.

    Science.gov (United States)

    Stanke, Gerd; Holm, Dirk; Woehrle, Tim

    1999-09-01

    Quality checking and part measurement are common needs in confectioning and manufacturing processes especially of electronic components. The complete part inspection of SMD- element, of connectors, of toy buildings blocks are such examples. For all these examples the demand arises to check parameters of different object sides by optical means with extremely high precision. The referred solution performs such inspection tasks from one point of view for (up to) five different sides, whereby four sides must be inspected for coplanarity and for the fifth the imprint quality has to be controlled. The optical set up uses special positioned mirrors combined with a sophisticated lighting system producing back light (coplanarity) as well as direct light (imprint inspection). The measurement procedure contains, of course, a calibration by help of a normal. The high precise measurement, better 10 micrometer, in the acquired image with a relatively low local resolution is reached by a spline based subpixel approach. Introducing cylindrical lenses or parabolic mirrors in the optical way allows to improve the potential accuracy for areas of interest, inside the view available for inspection.

    2014-09-15

    We analyze the defect scaling Lee–Yang model from the perturbed defect conformal field theory (DCFT) point of view. First the defect Lee–Yang model is solved by calculating its structure constants from the sewing relations. Integrable defect perturbations are identified in conformal defect perturbation theory. Then pure defect flows connecting integrable conformal defects are described. We develop a defect truncated conformal space approach (DTCSA) to analyze the one parameter family of integrable massive perturbations in finite volume numerically. Fusing the integrable defect to an integrable boundary the relation between the IR and UV parameters can be derived from the boundary relations. We checked these results by comparing the spectrum for large volumes to the scattering theory.

    The increasing influence exerted by Land governments on the investment policy of the power supply industry will have impacts on the commercial law system and on the regulatory regime that hitherto have not been considered. First signs of such a development are to be seen in, for example, the dispute among Land governments over the distribution of financial burdens resulting from the coal support programmes. The real problem behind this dispute however, is the question of how much and what kind of responsibility is to be assumed by the Land governments for structuring the energy supply system.

    2014-06-25

    From the point of view of the rheumatologist, the treatment of pain should be adjusted individually in accordance with medical principles based on the facts related to the relevant pathologies. This treatment includes conservative (medicinal and non-medicinal), interventional and surgical methods. The treatment does not just depend on the diagnosis, but also on the particular functional disability based on the ICF (International Classification of Functioning) and the level of polymorbidity. As rheumatology patients often have comorbidity, the choice of painkillers (NSAIDs, analgesics, opioids etc), immunosuppressants and physical therapy methods (physiotherapy, ergotherapy, etc) may be limited.

    formou-se um grupo focal com a participação de 16 parteiras. RESULTADOS: Encontrou-se uma atitude de não aceitação do aborto, induzido ou espontâneo. As mulheres que abortam são chamadas de "porcas", "imundas" ou "cadelas" e as parteiras mostram-se titubeantes em atendê-las. No entanto, é comum a prática da "regulação da menstruação" entre as mulheres da comunidade, ou seja, utilizam substâncias que induzem a menstruação quando a mesma está atrasada. CONCLUSÕES: O conhecimento de significados populares em torno do aborto é imprescindível para a construção de estratégias que reforcem os vínculos entre serviços institucionais de saúde e as parteiras tradicionais e para melhorar a qualidade da assistência às mulheres.OBJECTIVE: An evaluation of the perception, resources and practices regarding abortion of traditional midwives in a rural area in the municipality of Yecapixtla, state of Morelos, located in the central region of Mexico. METHODS: A qualitative methodology consisting of a detailed interview, focal groups and participating observation, was used. The subjects investigated were socio-cultural aspects, reproduction, sexuality and health related to abortion. Nine midwives were interviewed and a focal group was formed in which 16 midwives participated. RESULTS: The results demonstrated a profound rejection of abortion whether inducted or spontaneous. The former was considered a major sin and the latter a serious failure of a woman´s reproductive function. Women who abort are called "pigs", "hogs" or "bitches" and the midwives are reluctant to attend them. However, a common practice among the women in the community is to "regulate the menstruation", that is, to use substances that provoke menstruation when this is delayed. This specific practice is not considered abortive by these women. CONCLUSION: Local popular beliefs about abortion are indispensible for the construction of effective strategies, which when provided by the institutional

    Full Text Available This article presents a didactic experience for applying a digital game in Catalan classrooms of grades fifth and sixth of Primary Education. It explains and analyzes the effects of its implementation on the educational practice, taking the teachers’ viewpoint who participated in the experience. The paper is based on the digital game called Miquel Crusafont, a digital game supported by Generalitat de Catalunya. The study tries to understand the sense that such methodological innovation made for the selected group of eleven primary school teachers –of ages 24 to 52–. Interviews were done in order to see the teacher’s behaviours and to know their point of view. The results pointed that the teachers appreciated the potentiality of the digital game to develop diverse Math skills and encourage some collaborative learning activities. They also identified difficulties that obstructed the use of a digital game in classrooms: lack of time in the curriculum and some games in the market are not appropriate to teach or they do not have a user’s guide showing all the potentiality of the game.

    Full Text Available Sensor miniaturisation, improved battery technology and the availability of low-cost yet advanced Unmanned Aerial Vehicles (UAV have provided new opportunities for environmental remote sensing. The UAV provides a platform for close-range aerial photography. Detailed imagery captured from micro-UAV can produce dense point clouds using multi-view stereopsis (MVS techniques combining photogrammetry and computer vision. This study applies MVS techniques to imagery acquired from a multi-rotor micro-UAV of a natural coastal site in southeastern Tasmania, Australia. A very dense point cloud ( < 1–3 cm point spacing is produced in an arbitrary coordinate system using full resolution imagery, whereas other studies usually downsample the original imagery. The point cloud is sparse in areas of complex vegetation and where surfaces have a homogeneous texture. Ground control points collected with Differential Global Positioning System (DGPS are identified and used for georeferencing via a Helmert transformation. This study compared georeferenced point clouds to a Total Station survey in order to assess and quantify their geometric accuracy. The results indicate that a georeferenced point cloud accurate to 25–40 mm can be obtained from imagery acquired from 50 m. UAV-based image capture provides the spatial and temporal resolution required to map and monitor natural landscapes. This paper assesses the accuracy of the generated point clouds based on field survey points. Based on our key findings we conclude that sub-decimetre terrain change (in this case coastal erosion can be monitored.

  7. Evaluation of the search and rescue LEEWAY model in the Tyrrhenian Sea: a new point of view

    2016-08-01

    The trajectories' prediction of floating objects above the sea surface represents an important task in search and rescue (SAR) operations. In this paper we show how it is possible to estimate the most probable search area by means of a stochastic model, schematizing the shape of the object appropriately and evaluating the forces acting on it. The LEEWAY model,a Monte Carlo-based ensemble trajectory model, has been used; here, both statistical law to calculate the leeway and an almost deterministic law inspired by the boundary layer theory have been considered. The model is nested within the subregional hydrodynamic model TSCRM (Tyrrhenian Sicily Channel Regional Model) developed in the framework of PON-TESSA (Programma Operativo Nazionale; National Operative Program - TEchnology for the Situational Sea Awareness) project. The main objective of the work is to validate a new approach of leeway calculation that relies on a real person in water (PIW) event, which occurred in the Tyrrhenian Sea in July 2013. The results show that by assimilating a human body to a cylinder and estimating both the transition from laminar to turbulent boundary layer and the drag coefficients, it can be possible to solve a force balance equation, which allows the search area to be estimated with good approximation. This new point of view leads to the possibility of also testing the same approach for other different categories of targets, so as to overcome the limitations associated with the calculation of the leeway in the future by means of standard statistical law.

    The aim of the paper is to look at the medical terminology in three different languages--English, Russian and Slovak and to estimate the trends of synonym formation as well as their emphasizes role in communication. The author that the problem of synonymy is peculiar especially to clinical medicine terminology, i.e. it relates only to a small extent anatomical nomenclature. According to motivative signs of terms, synonyms are divided into 2 groups: equivalent and interpretative synonyms. In keeping with criteria determined by basic characteristics of a term in medical terminology there are often preferred international expressions. In recent years a great number of English expressions have entered into medical terminology due to the fact that English had became a language of international communication. From the practical point view undoubtedly, it is a positive tendency, because it facilitates international communication. In this respect Russian orthography is considered to be an exception, since Cyrillic alphabet often makes international communication more complicated. (Ref. 10.).

    International Nuclear Information System (INIS)

    The problems related to the environment are reported regularly to the public by means of the newspapers, on radio and television. The story is the product of a journalistic process and in general does not bear much resemblance to the original event. The rate and type of reportage depend not only on the body of data available to the journalist but on the information sources the journalist chosen to use. The same story is reported in a positive or negative way. Finally people are overwhelmed by contradictory information and became uncertain or frightened. In order to provide the general public with objective information about nuclear energy in particular and to made a statement about the position of the Belgian Catholic Church concerning this matter, the results of the study were published in Dutch under the form of a book with the title 'The Energy Sources and Nuclear Energy - Comparative analysis and ethical thoughts written the same author.

    On the occasion of the celebration of the first half-century of Yang--Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted physical reality, that is, its "phenomenology". There is nothing original in this work, except, perhaps, my own points of view. But I hope that the older practitioners of the field will find here grounds for nostalgia, or good reasons to disagree with me. Younger addicts may learn that history does not resemble at all what is reflected in current textbooks: it was orders of magnitude more fascinating.

Likewise I survey the birth of feminism and examine in what ways it has been helpful in women’s battle for equal rights. Se...

  12. Manipulating flow separation: sensitivity of stagnation points, separatrix angles and recirculation area to steady actuation

    CERN Document Server

    Boujo, Edouard

    2014-01-01

    A variational technique is used to derive analytical expressions for the sensitivity of several geometric indicators of flow separation to steady actuation. Considering the boundary layer flow above a wall-mounted bump, the six following representative quantities are considered: the locations of the separation point and reattachment point connected by the separatrix, the separation angles at these stagnation points, the backflow area and the recirculation area. For each geometric quantity, linear sensitivity analysis allows us to identify regions which are the most sensitive to volume forcing and wall blowing/suction. Validations against full non-linear Navier-Stokes calculations show excellent agreement for small-amplitude control for all considered indicators. With very resemblant sensitivity maps, the reattachment point, the backflow and recirculation areas are seen to be easily manipulated. In contrast, the upstream separation point and the separatrix angles are seen to remain extremely robust with respec...

  14. COMPARISON OF TWO VARIANTS OF A KATA TECHNIQUE (UNSU: THE NEUROMECHANICAL POINT OF VIEW

    Directory of Open Access Journals (Sweden)

    2009-11-01

    Full Text Available The objective of this work was to characterize from a neuromechanical point of view a jump performed within the sequence of Kata Unsu in International top level karateka. A modified jumping technique was proposed to improve the already acquired technique. The neuromechanical evaluation, paralleled by a refereeing judgment, was then used to compare modified and classic technique to test if the modification could lead to a better performance capacity, e.g. a higher score during an official competition. To this purpose, four high ranked karateka were recruited and instructed to perform the two jumps. Surface electromyographic signals were recorded in a bipolar mode from the vastus lateralis, rectus femoris, biceps femoris, gluteus maximus, and gastrocnemious muscles of both lower limbs. Mechanical data were collected by means of a stereophotogrammetric system and force platforms. Performance was associated to parameters characterizing the initial conditions of the aerial phase and to the CoM maximal height. The most critical elements having a negative influence on the arbitral evaluation were associated to quantitative error indicators. 3D reconstruction of the movement and videos were used to obtain the referee scores. The Unsu jump was divided into five phases (preparation, take off, ascending flight, descending flight, and landing and the critical elements were highlighted. When comparing the techniques, no difference was found in the pattern of sEMG activation of the throwing leg muscles, while the push leg showed an earlier activation of RF and GA muscles at the beginning of the modified technique. The only significant improvement associated with the modified technique was evidenced at the beginning of the aerial phase, while there was no significant improvement of the referee score. Nevertheless, the proposed neuromechanical analysis, finalized to correlate technique features with the core performance indicators, is new in the field and is a

  15. Automated Generation of Digital Terrain Model using Point Clouds of Digital Surface Model in Forest Area

    2011-04-01

    Full Text Available At present, most of the digital data acquisition methods generate Digital Surface Model (DSM and not a Digital Elevation Model (DEM. Conversion from DSM to DEM still has some drawbacks, especially the removing of off terrain point clouds and subsequently the generation of DEM within these spaces even though the methods are automated. In this paper it was intended to overcome this issue by attempting to project off terrain point clouds to the terrain in forest areas using Artificial Neural Networks (ANN instead of removing them and then filling gaps by interpolation. Five sites were tested and accuracies assessed. They all give almost the same results. In conclusion, the ANN has ability to obtain the DEM by projecting the DSM point clouds and greater accuracies of DEMs were obtained. If the size of the hollow areas resulting from the removal of DSM point clouds are larger the accuracies are reduced.

    The continuation of cancer chemotherapy was examined from the view point of the patient's economic burden and the national finance. Along with the rapid technological progress, anti-cancer drugs become more and more expensive. According to our survey, not a little patient was obliged to give up the most appropriate treatment due to some economic reasons. The impact of the increasing cost of cancer treatment and the rational measure to minimize the patient's burden were discussed. The mean out-of-pocket expense of the patients without economic worries was three-fourths that of the patients with economic worries. In other words, if the economic burden is reduced by around a quarter in the patients whose burden is heavy, they would certainly receive optimal medical care. As for the situation in which the cancer chemotherapy have to be interrupted due to the constraint of limited funding, it seemed difficult to continue to avoid this thoroughly in the future without the drastic reform of medical insurance system. The importance to set priorities and allocate human and financial resources within the financial crunch was discussed while making reference to health care reforms of several western countries in the late 1990's.

  17. A thought on enterprise knowledge management from the document management's point of view

    International Nuclear Information System (INIS)

    As an important innovation of modern management concept, Knowledge Management has been applied in fields as enterprise management and government administration, and has become an important development direction of document management. However, KM currently is still in an embarrassing position in China. As a modern management concept, KM has to exert its function sufficiently by using modern technology. To implement enterprise KM strategy successfully, we need to evaluate enterprise's strategic objectives, organization, system, technology, personnel, capital, work flow, knowledge flow, culture and so on exactly and roundly, to persist in the humanity-based principle, to find out the factors that block the implantation of enterprise KM, to define the objectives of enterprise KM, and accordingly, to formulate corresponding implementation plan and strategy, and to chose appropriate KM tools, etc. From the document management's point of view, KM concept could and should be integrated with digital library and digital archives to construct digital library/digital archives of knowledge management type; to find out the breakthrough of KM and to do the basic jobs of KM well, that includes integrating all kinds of literature resources efficiently, improving the document management level, and constructing different kinds of enterprise knowledge repositories according to user's requirement.

  19. Laser diagnostic and therapy of dental caries: the clinic point of view

    International Nuclear Information System (INIS)

    Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

  20. Dynamical downscaling: Fundamental issues from an NWP point of view and recommendations

    Hong, Song-You; Kanamitsu, Masao

    2014-01-01

    Dynamical downscaling has been recognized as a useful tool not only for the climate community, but also for associated application communities such as the environmental and hydrological societies. Although climate projection data are available in lower-resolution general circulation models (GCMs), higher-resolution climate projections using regional climate models (RCMs) have been obtained over various regions of the globe. Various model outputs from RCMs with a high resolution of even as high as a few km have become available with heavy weight on applications. However, from a scientific point of view in numerical atmospheric modeling, it is not clear how to objectively judge the degree of added value in the RCM output against the corresponding GCM results. A key factor responsible for skepticism is based on the fundamental limitations in the nesting approach between GCMs and RCMs. In this article, we review the current status of the dynamical downscaling for climate prediction, focusing on basic assumptions that are scrutinized from a numerical weather prediction (NWP) point of view. Uncertainties in downscaling due to the inconsistencies in the physics packages between GCMs and RCMs were revealed. Recommendations on how to tackle the ultimate goal of dynamical downscaling were also described.

  3. High energy heavy ion collisions from the view point of the 'strong field physics'

    International Nuclear Information System (INIS)

    In the high energy heavy ion collisions at the facilities like RHIC and LHC, two strongest fields in the present universe are generated. First of all, a very strong electromagnetic field is generated, though its duration is very short due to the very high speed collisions of nuclei and the large electric charges. On the other hand, the nuclei are described as the high density saturation gluon state just before the moment of the collision and the high density gluon is released by the collision. A very strong color electromagnetic field is generated. The color glass condensate (CGC) is a reasonable picture. In this text, dynamics of the GLASMA (Glass + plasma), the new physics brought about by those 'strong fields', are introduced and are explained how the yet unsolved problems of the heavy ion collisions are going to be investigated on the new view point. The mechanism of the apparitions of the strong electromagnetic field and the strong color electromagnetic field are explained at first. The heavy ion collisions can be described as the process CGC to develop into QGP. As the phenomena under the strong electromagnetic field and the heavy ion collisions, their synchrotron radiations, the photon birefringence, the photon decay, the splitting of photons and the chiral phase transitions under high field are picked up. Concerning the strong color electromagnetic field dynamics and the heavy ion collisions, the plasma flux tube dynamics, the color magnetic flux tube, the color electric flux tube and the coexisting case of the color electric field and magnetic field are presented.

    2016-01-01

    Abstract Background Orthopedic surgical education is evolving as educators search for new ways to enhance surgical skills training. Orthopedic educators should seek new methods and technologies to augment and add value to real-time orthopedic surgical experience. This paper describes a protocol whereby we have started to capture and evaluate specific orthopedic milestone procedures with a GoPro® point-of-view video camera and a dedicated video reviewing website as a way of supplementing the current paradigm in surgical skills training. We report our experience regarding the details and feasibility of this protocol. Methods Upon identification of a patient undergoing surgical fixation of a hip or ankle fracture, an orthopedic resident places a GoPro® point-of-view camera on his or her forehead. All fluoroscopic images acquired during the case are saved and later incorporated into a video on the reviewing website. Surgical videos are uploaded to a secure server and are accessible for later review and assessment via a custom-built website. An electronic survey of resident participants was performed utilizing Qualtrics software. Results are reported using descriptive statistics. Results A total of 51 surgical videos involving 23 different residents have been captured to date. This includes 20 intertrochanteric hip fracture cases and 31 ankle fracture cases. The average duration of each surgical video was 1 hour and 16 minutes (range 40 minutes to 2 hours and 19 minutes). Of 24 orthopedic resident surgeons surveyed, 88% thought capturing a video portfolio of orthopedic milestones would benefit their education Conclusions There is a growing demand in orthopedic surgical education to extract more value from each surgical experience. While further work in development and refinement of such assessments is necessary, we feel that intraoperative video, particularly when captured and presented in a non-threatening, user friendly manner, can add significant value to the

    2015-12-01

    It is known that tsunamis are rather rare events, especially when compared to earthquakes, and the Italian coasts are no exception. Nonetheless, a striking evidence is that 6 out of 10 earthquakes occurred in the last thousand years in Italy, and having equivalent moment magnitude equal or larger than 7 where accompanied by destructive or heavily damaging tsunamis. If we extend the lower limit of the equivalent moment magnitude down to 6.5 the percentage decreases (around 40%), but is still significant. Famous events like those occurred on 30 July 1627 in Gargano, on 11 January 1693 in eastern Sicily, and on 28 December 1908 in the Messina Straits are part of this list: they were all characterized by maximum run-ups of several meters (13 m for the 1908 tsunami), significant maximum inundation distances, and large (although not precisely quantifiable) numbers of victims. Further evidences provided in the last decade by paleo-tsunami deposit analyses help to better characterize the tsunami impact and confirm that none of the cited events can be reduced to local or secondary effects. Proper analysis and simulation of available tsunami data would then appear as an obvious part of the correct definition of the sources responsible for the largest Italian tsunamigenic earthquakes, in a process in which different datasets analyzed by different disciplines must be reconciled rather than put into contrast with each other. Unfortunately, macroseismic, seismic and geological/geomorphological observations and data typically are assigned much heavier weights, and in-land faults are often assigned larger credit than the offshore ones, even when evidence is provided by tsunami simulations that they are not at all capable of justifying the observed tsunami effects. Tsunami generation is imputed a-priori to only supposed, and sometimes even non-existing, submarine landslides. We try to summarize the tsunami research point of view on the largest Italian historical tsunamigenic

  12. Implications of Harvest on the Boundaries of Protected Areas for Large Carnivore Viewing Opportunities.

    Full Text Available The desire to see free ranging large carnivores in their natural habitat is a driver of tourism in protected areas around the globe. However, large carnivores are wide-ranging and subject to human-caused mortality outside protected area boundaries. The impact of harvest (trapping or hunting on wildlife viewing opportunities has been the subject of intense debate and speculation, but quantitative analyses have been lacking. We examined the effect of legal harvest of wolves (Canis lupus along the boundaries of two North American National Parks, Denali (DNPP and Yellowstone (YNP, on wolf viewing opportunities within the parks during peak tourist season. We used data on wolf sightings, pack sizes, den site locations, and harvest adjacent to DNPP from 1997-2013 and YNP from 2008-2013 to evaluate the relationship between harvest and wolf viewing opportunities. Although sightings were largely driven by wolf population size and proximity of den sites to roads, sightings in both parks were significantly reduced by harvest. Sightings in YNP increased by 45% following years with no harvest of a wolf from a pack, and sightings in DNPP were more than twice as likely during a period with a harvest buffer zone than in years without the buffer. These findings show that harvest of wolves adjacent to protected areas can reduce sightings within those areas despite minimal impacts on the size of protected wolf populations. Consumptive use of carnivores adjacent to protected areas may therefore reduce their potential for non-consumptive use, and these tradeoffs should be considered when developing regional wildlife management policies.

  14. Aspects of industrial psychology in power plant operation from the employee's point of view

    International Nuclear Information System (INIS)

    The working-psychological stress of the colleagues during their duty hours in a nuclear power plant is lined out with respect to education, maintenance and proof of the technical qualification. Of special significance is the behaviour of the staff during pre-commissioning, commissioning, normal operation and abnormal operation of a nuclear power plant. In line of duty special stress is added for employees by the strange behaviour of politicians, mass-media and neighbours. The proposals for modification in relation to the education of shift supervisors are shown in a critical view. (orig.)

    When we think about ethics or morals, we tend to look at them from the viewpoint of here and now. Actual implications of then and there, however, could be different. That is why we should study history of bio-ethics along with philosophy involved in it. Bio-medical ethics is situated in spatial and cultural dimension as well as temporal and historical. Dentistry has been in a peculiar situation in that although it has evolved from the same root as medicine, it has become a separate discipline. Ethical implications of dentistry, however, share the historical and philosophical background with its mother discipline, i.e., medicine, surgery, barber-surgery and even smithery. This paper tries to grasp the main ideas of bio-medical ethics from the ancient Greek and China, and picks up three of them as guiding principles, i.e., deontology and teleology from the west and self-cultivation from the east. It also tracks down the contents of modern biomedical ethics; from etiquette to ethics, from morals to contract (ethics of autonomy), and ethics of professional responsibility. Finally it reviews and analyzes two different traditions of dental professional regulation from the legal and ethical point of view (U.S. and Europe), and proposes a new direction for the construction of dental ethics in Korea.

Reviewing related literature and presenting examples that show the analysis of the sentence according to each grammatical school, briefly. Each type of the three grammatical approaches has different terminology and yet strategy when analysing a sentence. For instance, in traditional grammar the sentence is divided into units, into patterns in structural grammar and into elements and phrases in transformational grammar. In addition, in both traditional and structural grammars, a number of sentences which have identical meanings with different word order are considered totally different from one another when being analysed; whereas, in transformational grammar the sentences share the same base and are analysed in terms of surface and deep structure(s for each one. The three presented grammatical approaches can be arranged in terms of the most detailed approach as: transformational grammar, traditional, and finally structural grammar.

    2012-01-01

    Let C be an irreducible projective curve of degree d in Pn(K), where K is an algebraically closed field, and let I be the associated homogeneous prime ideal. We wish to compute generators for I, assuming we are given sufficiently many points on the curve C. In particular if I can be generated by polynomials of degree at most m and we are given md + 1 points on C, then we can find a set of generators for I. We will show that a minimal set of generators of I can be constructed in polynomial time. Our constructions are completely independent of any notion of term ordering; this allows us the maximal freedom in performing our constructions in order to improve the numerical stability. We also summarize some classical results on bounds for the degrees of the generators of our ideal in terms of the degree and genus of the curve.

    In recent years, a peculiar phenomenon has happened time and time again and aroused hot social discussions in China. It is the fact that when an old man (or woman) falls down on the street, most passers-by dare not to help him, or in other cases, when one of them does offer his (or her) help, he might be accused of having knocked the old man down. As a result, nowadays in China, most people will not help a fallen old man for fear of being falsely accused. From an economic point of view, this ...

  1. PET and diagnostic technology evaluation in a global clinical process. DGN's point of view

    International Nuclear Information System (INIS)

    The German Society of Nuclear Medicine (DGN) criticizes the methodological approach of the IQWiG for evaluation of PET and the conclusions, which represent the opposite point of view compared to the most other European countries and health companies in the USA: (1) Real integration of experienced physicians into the interpretation of data and the evaluation of effectiveness should be used for best possible reporting instead of only formal hearing. (2) Data of the National Oncologic PET Registry (NOPR) from the USA have shown, that PET has changed the therapeutic management in 38% of patients. (3) The decision of the IQWiG to accept outcome data only for their benefit analyses, is controversial. Medical knowledge is generated by different methods, and an actual analysis of the scientific guidelines has shown that only 15% out of all guidelines are based on the level of evidence demanded by the IQWiG. Health economics has created different assessment methods for the evaluation of a diagnostic procedure. The strategy chosen by the IQWiG overestimated the perspective of the population and undervalue the benefit for an individual patient. (4) PET evaluates the effectiveness of a therapeutic procedure, but does not create an effective therapy. When the predictive value of PET is already implemented in a specific study design and the result of PET define a specific management, the trial evaluate the whole algorithm and PET is part of this algorithm only. When PET is implemented as test during chemotherapy or by the end of chemotherapy, the predictive value of PET will depend decisively on the effectiveness of the therapy: The better the therapy, the smaller the differences in survival detected by PET. (5) The significance of an optimal staging by the integration of PET will increase. Rationale is the actual development of ''titration'' of chemotherapy intensity and radiation dose towards the lowest possible, just about effective dosage. (6) The medical therapy of

    Full Text Available In this article based upon empiric empirical experimental research, we disclose point of view from students, teachers and parents side. Highlighting school and parents influence to students attitude to education importance. Disclosing different views on education between 10th and 12th grade students. Students view on modern youths values shows that they don’t really care about education (10th grade – 7%, 12th grade – 9%. The most valuable thing is money (10th gr. – 23%, 12th gr. – 32%, and independence (10th gr. – 23%, 12th gr. – 33%. This shows us that material fulfillment, as they think, leads to successful future. So in this case “fast” money and independence becomes a successful life standard. However answer to question what is most important to them personally education is most reachable value (10th gr. – 58%, 12th gr. – 49%. This shows us that youth is not ready (psychologically prepared to open up their true values. In the other hand that shows us lack of openness in our relationship. Personally highest rates goes to education (10th gr. – 58%, 12th gr. – 49%; communication and collaboration (10th gr. – 52%, 12th gr. – 45%, self esteem (10th gr. – 48%, 12th gr. – 49%, honesty (10th gr. – 41%, 12th gr. – 37%. In conclusion we can say that social relationship and collaboration helps to achieve goals, in this case – education. Most of students are looking forward to achieve higher education (10th gr. – 43%, 12th gr. – 46%. Planning to study in Lithuania (10th gr. – 44%, 12th gr. – 50%. Students planning to go for postgraduate studies (10th gr. – 18%, 12th gr. – 25%. This shows us that not only 12th grade students, but also 10th grade students understand higher education importance. It is not a surprise that amount of postgraduate students is growing each year. Achievement of higher education students are linking with opportunity to make more money (10th gr. – 26%, 12th gr. – 32%; getting

    Quantitative knowledge of the magnitude, extent and trends of the Digital Divide are critical to understand and identify the regions most in need of help, to make rational decisions on how to address the problems and to make cases for executives, funding agencies and politicians. We report on a project (PingER) to measure the Digital Divide from the point of view of Internet performance. The PingER project has been measuring Internet performance since 1995 and with the increased emphasis on measuring and tracking the Digital Divide, it now covers over 700 hosts in over 150 countries that between them contain over 99% of the world's Internet connected population. In this paper we will describe the how PingER works, it deployment, the data analysis, and presentation. We also introduce a new PingER visualization tool (ViPER) that provides a more appealing interactive visualization of the PingER data and also works on mobile PDAs. We will also show results from PingER that illustrate the magnitude, extent and trends for the Digital Divide, and also compare PingER results with some human development and technology indices.

    Full Text Available Introduction: Feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. This study aimed to assess the residents’ points of view about feedback in clinical education at Shiraz University of Medical Sciences. Methods: The sample of this study included 170 medical residents attending medical workshops in Shiraz University of Medical Sciences. The residents filled a valid and reliable questionnaire containing 21 items on their perceptions of the feedback they got throughout the workshops. The data were analyzed using SPSS version 14. Results: The study revealed that residents, generally, have a positive perception of feedback in their training. The highest score belonged to the items such as “feedback was applicable to future work”, “feedback corrected my behavior”, “feedback worked as a motivation for education” and “feedback was specific in one subject”. Residents who had a negative feedback experience also increased their efforts to learn. The Surgery residents acquired the highest scores while radiology residents got the lowest. The difference between these groups was statistically significant (P = 0.000. Conclusion: The highest mean score belonged to internal medicine residents. This shows that residents believe that obstetrics & gynecology ward is a ward in which the formative assessment is much more powerful in comparison to the other three major wards. The surgery ward received the lowest score for formative assessment and this shows that the feedback in surgery ward is very low.

    Non-point source loads of heavy metals from contaminated soil has increasingly become the major cause of heavy metal concentrations of rivers and lakes surpassed the limitation value, while only few studies had focused on quantitative monitoring of soil heavy metal transportation to water, in situ field conditions. As reported, agricultural farmland heavy metal contamination was the major contamination problem, especially for cadmium (Cd) pollution in middle and downstream of Xiangjiang River. This study selected the typical Cd polluted agricultural watershed for a case study, three typical landuse types of rice, dry farmland and unused grassland with three replicate quadrates were carried out for natural rainfall runoff hydrology processes monitoring, from 2011-2012. Results showed that, precipitation pH value increased from spring to summer, soluble Cd concentration of spring runoff was significantly higher than that of summer rainfall runoff, which presented an obviously seasonal heterogeneity and had a negative correlation with rainfall pH value, and rainfall pH value can obviously impact soil soluble Cd transportation into surface runoff charge. In the same rainfall event, soluble Cd concentration and non-point load of rice were significantly lower than those of dry land and unused grassland, while no obviously seasonal trend was found for non-point load of Cd from three typical landuse types because of the rainfall depth variance, which needs more researches and concerns in the future. These results can provide valuable data and scientific supports for watershed scale's heavy metal non-point source load quantitative estimation and water environment management and water quality diagnosis and early warning.

    International scientific optical network (ISON) project achieved all initially formulated goals. ISON is the world-wide system providing periodical monitoring of space objects in GEO region across the globe. New level of quality of GEO research is achieved. For the first time our knowledge of true GEO population of objects brighter than 15.5m is almost complete. ISON provides the discovering and tracking of faint deep space debris. Large amount of data on long time intervals is obtained for few hundred fragments including ones having high area-to-mass ratio. About 1115000 measurements in 120000 tracks are collected and processed at KIAM database in 2009 that allowed to maintain the orbits of 1467 GEO objects including 892 spacecraft, 250 upper stages and AKMs and 325 fragments and objects of undetermined type. ISON administrative, software and engineering groups are formed to support current project activities. 20 new telescopes were produced as a part of this work. At the same time ISON is involved into new scientific and applied projects which are formulating new tasks and needing further ISON development. Part of ISON is involved into Roscosmos project aimed on search and prediction of possible collisions between operational spacecraft and other space objects. Therefore it is required that periodicity of object monitoring and measurement precision would be improved. It is necessary to involve new observatories to minimize the weather dependence as well as dedicated telescopes to provide additional tracking of potentially dangerous objects. The goal of HEO object population studying requires development of dedicated telescopes with wider field of view for monitoring of larger areas of the sky. KIAM, as the ISON project leader, is responsible also for development of the new model of the small object population (in first turn for high orbits) that requires involvement of additional large aperture telescopes to verify the model. In addition, dedicated ISON subsystem

    Full Text Available The way one conceives disabled people seems to influence the actions directed toward them. Occupational therapists constitute a part of health professionals that direct their actions based on a comprehensive view of disability. The aim of this study was to identify and analyze the conception of disability from the standpoint of occupational therapists. Fifteen university teachers of Occupational Therapy undergraduate courses participated in this study: seven from public universities and eight from private institutions, located in mid-sized municipalities in the state of São Paulo. The data were collected by means of a scale denominated “Escala de Avaliação da Concepção de Deficiência” (Rating Scale for Conception of Disability. The results show that the subjects tend to follow interactional, social conceptions of disability. This study yields contributions to understand the conception of disability held by teachers of Occupational Therapy. This conception certainly guides their teaching performance and affects the training of future professionals.

    Tomas Bayo, Ricard; Parro, Gema

    2015-04-01

    Establishment of large wind farms requires enormous investments putting steadily greater emphasis on optimal topology design and control of these. This requires not only an optimization of the power output, but also the development of strategies to cope with the higher loading expected. The cornerstone of such strategies is a realistic characterization and modelling of the wake flow field inside the wind farm, beyond Frandsen's equivalent turbulence method. Whereas Frandsen model has been mostly considered in the industry so far, it has not proved completely satisfactory when facing current problems such as wake effects on turbines placed at short distances or consequences of half wake for turbine loading. The objective of the present work is to address these questions from a certification point of view within the framework of Risoe's Dynamic Wake Meandering (DWM) model. The DWM model is based on the combination of three parts: modeling of quasi-steady wake deficits, a stochastic model of the downwind wake meandering and an added or self-generated wake turbulence. The analysis carried out is two-fold: First, a comparative study of the wake effects generated in Frandsen model as well as in various realizations of the DWM model is performed. For this purpose wake-induced loads are calculated using two different aeroelastic codes: HAWC2 and Bladed. Second, the applicability of DWM for the assessment of wind turbines under site-specific conditions is discussed and the conclusions summarized in a Recommended Practice. Clear prescriptions are thereby provided for the use of DWMM for site suitability assessments, including the aforementioned extreme situations, along with the interpretation of the future version of the IEC 61400-1 standards.

    The purpose of this work is to analyze the process of importation, that is a part of the sanitary control of psychotropic substances, made by Brazilian National Health Surveillance Agency's ports, airports and borders. For this work, psychotropic substances are defined as active pharmaceutical raw materials present in the list B1 of Portaria nº 344/98; which need Anvisa's permission to be imported. For this purpose we used semistructured interviews with key informers and participant observation. The information were collected and systematized through the content analysis, thematic modality. The results show a very complex control which involves an intense bureaucratic process. The main identified critical points of the process were: the information system precariousness; the absence of human resources; deficiency of laboratorial support and infra-structure at customs. Anvisa's web page and the specific law are strong points of the process, but still needing improvements. We understood that despite of the progress made, there are many things to do for giving the country an efficient health control system to the importation of these substances. PMID:21120327

  13. Statistical point of view on nucleus excited states and fluctuations of differential polarization of particles emitted during nuclear reactions

    International Nuclear Information System (INIS)

    As previous works notably performed by Ericson outlined the fact that the compound nucleus model resulted in variations of efficient cross sections about average values and that these variations were not negligible at all as it had been previously admitted, this research thesis aims at establishing theoretical predictions and at showing that Ericson's predictions can be extended to polarization. After having qualitatively and quantitatively recalled the underlying concepts used in the compound nucleus and direct interaction models, the author shows the relevance of a statistical point of view on nuclei which must not be confused with the statistical model itself. Then, after a recall of results obtained by Ericson, the author reports the study of the fluctuations of differential polarization, addresses the experimental aspect of fluctuations, and shows which are the main factors for this kind of study

    The aim of the article is to analyze the decentralization of political structure, with a view to reducing the influence of economical incentives of organized interests on the distribution of public resources. The theoretical deliberations presented in the article are based on the research achievements of the new political economy (NPE). The author argues that the federal jurisdiction where the administration have the power to levy taxes is the closest to nondiscriminatory politics.

    2006-01-01

    FRW cosmologies with conformally coupled scalar fields are investigated in a geometrical way by the means of geodesics of the Jacobi metric. In this model of dynamics, trajectories in the configuration space are represented by geodesics. Because of the singular nature of the Jacobi metric on the boundary set $\\partial\\mathcal{D}$ of the domain of admissible motion, the geodesics change the cone sectors several times (or an infinite number of times) in the neighborhood of the singular set $\\partial\\mathcal{D}$. We show that this singular set contains interesting information about the dynamical complexity of the model. Firstly, this set can be used as a Poincar{\\'e} surface for construction of Poincar{\\'e} sections, and the trajectories then have the recurrence property. We also investigate the distribution of the intersection points. Secondly, the full classification of periodic orbits in the configuration space is performed and existence of UPO is demonstrated. Our general conclusion is that, although the pre...

  6. Ozone Monitoring Instrument flight-model on-ground calibration from a scientific point of view

    In 2002 the on-ground calibration of the flight-model of the Ozone Monitoring Instrument (OMI), scheduled for launch in January 2004 on the EOS-AURA satellite, was performed by the industrial contractor in close cooperation with the Principal Investigator team from the Royal Netherlands Meteorological Institute (KNMI) and the scientific Calibration Working Group with members from The Netherlands, Finland, and the United States. OMI will observe the Earth in nadir with a field of view of 114 degrees, providing a daily Earth coverage. The instrument observes the sun once per day via one of three on-board diffusers, and once per week and month via one of the other two diffusers, respectively, to monitor the diffuser degradation. The instrument is equipped with an internal white light source for detector calibration purposes. This presentation will focus on the measurements, analyses and preliminary results of the on-ground calibration from a scientific perspective, which are particularly important for meeting the scientific objectives of the OMI instrument. The OMI instrument is operated in flight at close to vacuum pressure and at temperatures of the CCD detectors and the instrument optical bench of 266 K and 265 K, respectively. Special attention is therefor given to the methods for obtaining a flight-representative on-ground calibration of the instrument. The OMI instrument has a large observational swath field of view of 114 degrees and a high spectral resolution. For this reason the on-ground calibration of the swath angle dependence of the radiometric calibration and the calibration description of spectral instrument features are discussed in the presentation. The spectral instrument features are important in view of the Differential Optical Absorption Spectroscopy (DOAS) retrieval technique used for the OMI instrument. They originate from the innovative polarisation scrambling device in the Earth mode and from the three on-board diffusers in the sun mode

    This paper presents a new method for convective flux approximation based on inclusions of skew points. The scheme uses the truncated terms of QUICK scheme and with the aid of an equation extracted from momentum equations, the skew points will appear in the convective flux formula. The results show that the presented scheme has better accuracy than the other schemes. Diffusion fluxes are approximated using power law scheme and for evaluation of the performance of the presented method several test cases were carried out and the results are compared with the results of other numerical works and experimental data.

  8. Recent Advances in Optimal Design of Structures from a Reliability Point of View

    DEFF Research Database (Denmark)

    Thoft-Christensen, Palle; Sørensen, John Dalsgaard

    1987-01-01

    Structural optimisation and structural reliability theory are considered. Both of these areas have developed during the last two decades from being of purely theoretical interest to areas useful in practical design. The main elements of structural reliability theory are described in the second...... section. First, a short review of the reliability theory for structural elements (e.g., beams and tubular joints) based on the so-called ß-index philosophy (Cornell[1], Ditlevsen[2], and Hasofer and Lind[3]) is given. Detailed descriptions are given in textbooks such as those by Thoft......-Christensen and Baker[4] and Madsen et al.[5]. Next a heuristic method, the so-called ß-unzipping method[6] is mentioned. This method can be used to estimate the reliability of a structural system if some modelling assumptions are fulfilled. In the third section some elements of structural optimisation theory...

  9. Constructivisms from a genetic point of view: a critical classification of current tendencies.

    Science.gov (United States)

    Sánchez, José Carlos; Loredo, José Carlos

    2009-12-01

    In this paper, we propose a critical classification of contemporary constructivist orientations. Our fundamental theoretical reference is the notion of genesis, understood as the construction of reality in a way that is neither relativist nor positivist-realist. We identify a nucleus of classic, genetic constructivism that revolves around the ideas of Baldwin, Piaget and Vygotsky and discuss two tendencies that distort the spirit of that nucleus: objectivism and subjectivism. Objectivism rules out the psychological, constructive activity of the subject, subordinating (or just reducing) it to objective structures either from nature (like genetic endowment or neural functioning), or from culture (like language or social practices). Subjectivism completely detaches the objectivity of knowledge from its construction on the part of the subject, reducing it to the mere product of individual interest, view, or irrationality. Thus, subjectivism is the non-constructive way to conceive the subject. Then, we attempt to show the dialectics that exists between these two tendencies and the scope of our criteria by analysing a representative (non exhaustive) group of authors who are defined as constructivists or who bring important elements to the debate about constructivism.

    The recent developments in the area of high-performance computing are driven not only by the desire for ever higher performance but also by the rising costs of electricity. The use of various types of accelerators like GPUs, Intel Xeon Phi has become mainstream and many algorithms and applications have been ported to make use of them where available. In Financial Mathematics the question of optimal use of computational resources should also take into account the limitations on space, because in many use cases the servers are deployed close to the exchanges. In this work we evaluate various algorithms for option pricing that we have implemented for different target architectures in terms of their energy and space efficiency. Since it has been established that low-discrepancy sequences may be better than pseudorandom numbers for these types of algorithms, we also test the Sobol and Halton sequences. We present the raw results, the computed metrics and conclusions from our tests.

    2015-09-01

    This research was designed to investigate the conceptualisations and thinking strategies Indigenous Australian students use in counting tasks. Eighteen Aboriginal students, in years 1 to 11 at a remote community school, were interviewed using standard counting tasks and a `counting' task that involved fetching `maku' (witchetty grubs) to have enough to give a maku to each person in a picture. The tasks were developed with, and the interviews conducted by, an Aboriginal research assistant, to ensure appropriate cultural and language contexts. A main finding was that most of the students did not see the need to use counting to make equivalent sets, even though they were able to demonstrate standard counting skills. The findings highlight a need to further examine the world views, orientations and related mathematical concepts and processes that Indigenous students bring to school.

    2014-07-01

    The organization of lubricant molecules confined between two solid surfaces when the lubricant film thickness is at the nanoscale is unknown. In this work, an ordering process of nematic liquid crystal molecules is observed by in situ polarized Raman spectroscopy of the lubricated point contact area. Our experimental results indicate that 4-n-pentyl-4'-cyanobiphenyl liquid crystal molecules orient along the rotation direction when the linear speed exceeds 12.6 mm/s, and the degree of order increases with linear speed. The relationship between the observed orientation and physical properties of the lubricant film is investigated. Isotropic orientation is observed at the outlet area of the contact region. The orientation behavior of liquid crystal molecules in a confined area is observed and the relationship between lubrication conditions and molecular orientation is discussed.

    2013-05-01

    With an advent of autostereoscopic display technique and increased needs for smart phones, there has been a significant growth in mobile TV markets. The rapid growth in technical, economical, and social aspects has encouraged 3D TV manufacturers to apply 3D rendering technology to mobile devices so that people have more opportunities to come into contact with many 3D content anytime and anywhere. Even if the mobile 3D technology leads to the current market growth, there is an important thing to consider for consistent development and growth in the display market. To put it briefly, human factors linked to mobile 3D viewing should be taken into consideration before developing mobile 3D technology. Many studies have investigated whether mobile 3D viewing causes undesirable biomedical effects such as motion sickness and visual fatigue, but few have examined main factors adversely affecting human health. Viewing distance is considered one of the main factors to establish optimized viewing environments from a viewer's point of view. Thus, in an effort to determine human-friendly viewing environments, this study aims to investigate the effect of viewing distance on human visual system when exposing to mobile 3D environments. Recording and analyzing brainwaves before and after watching mobile 3D content, we explore how viewing distance affects viewing experience from physiological and psychological perspectives. Results obtained in this study are expected to provide viewing guidelines for viewers, help ensure viewers against undesirable 3D effects, and lead to make gradual progress towards a human-friendly mobile 3D viewing.

    Global awareness of natural calamities increased after the destructive Indian Ocean tsunami of December 2004, largely because many foreigners lost their lives, especially in Thailand. This paper explores how best to communicate the seismic risk posed by different travel destinations to crisis management personnel in tourists' home countries. The analysis of seismic risk should be straightforward enough for non-specialists, yet powerful enough to identify the travel destinations that are most at risk. The output for each location is a point in 3D space composed of the natural and built-up environment and local tourism. The tourism-specific factors can be tailored according to the tourists' nationality. The necessary information can be collected from various directories and statistics, much of it available over the Internet. The output helps to illustrate the overall seismic risk conditions of different travel destinations, allows for comparison across destinations, and identifies the places that are most at risk.

    2010-10-01

    This study tested the effects of distraction using virtual-reality (VR) technology on acute pain tolerance in young adults. Forty-one undergraduate students, aged 18-23 years, used a VR head-mounted display helmet, steering wheel, and foot pedal to play an auto racing video game while undergoing exposure to very cold water (cold pressor set at 1 °C). Two different game views were tested that were hypothesized to affect the degree to which participants felt "present" in the virtual environment: a first-person view, in which the participant saw the virtual environment through the eyes of the game character being manipulated; and a third-person view, in which the participant viewed the game character from a distance. The length of time participants tolerated the cold-water exposure (pain tolerance) under each distraction condition was compared to a baseline (no distraction) trial. Subjects also rated the degree to which they felt "present" in the virtual environment after each distraction trial. Results demonstrated that participants had significantly higher pain tolerance during both VR-distraction conditions relative to baseline (no distraction) trials. Although participants reported a greater sense of presence during the first-person condition than the third-person condition, pain-tolerance scores associated with the two distraction conditions did not differ. The types of VR applications in which presence may be more or less important are discussed.

    2011-01-01

    This study aimed to characterize the use of five critical safety behaviors by tree fallers at different skill levels, and to test the feasibility of using a helmet camera to observe work activities directly in a remote environment. Small cameras were mounted on standard hard-hats. Video data were obtained for pairs of fallers at four different skill levels, from beginning students to professional fallers. Critical action steps during tree episodes were coded and compared. Critical action steps for fallers were successfully distinguished during work activities. Notable differences were observed among fallers in different skill categories and between individual fallers. This study found that the helmet camera worked well for observing faller work behavior, and that point-of-view video observation may be used to evaluate student loggers and training programs. We also found that professional fallers may have been exposed to increased hazard; care should be observed with helmet cameras designed for professionals. PMID:22069927

  7. Influence of neutron correlations on nuclear break-up reaction both from theoretical and experimental point of view

    International Nuclear Information System (INIS)

    Nuclear break-up has been studied both from an experimental and a theoretical point of view and has shown to be a powerful tool to probe nucleon correlations in nuclei. A theory beyond mean-field, called TDDM, (Time Dependant Density Matrix) taking into account two-body correlations has been developed. The dynamical evolution of a correlated nuclei can be described and especially nuclear break-up. This study shows that the distributions of relative angle between the two neutrons strongly differ when varying initial correlations: two nucleons close together in the nuclei will lead to small relative angle after emission whereas two nucleons far from each other gives large relative angles. From an experimental point of view, correlations between the two neutrons in the halo of the Borromean nucleus He6 have been investigated. Its ground state is predicted to have two dominant configurations: the di-neutron configuration where the two neutrons are very close to each other and the cigar configuration, where the two neutrons are on opposite side with respect to the core. Nuclear break-up of He6 on a lead target has been studied at GANIL with a SPIRAL beam. The alpha particles coming out of the break-up where detected by a stripped Silicon detector coupled to a Silicon-Lithium detector and the neutrons by EDEN and the Neutron Wall, in order to get a large angular coverage. Angular correlation functions extracted from data show both strong correlation at small relative angles and at large relative angle corresponding respectively to the contribution of the di-neutron configuration and of the cigar like configuration. So He6 ground state seems to be a superposition of these two configurations. (author)

    Teeri, S; Välimäki, M; Katajisto, J

    1998-01-01

    The aim of this study was to describe the views of demented patients' relatives concerning the fulfillment of patients' rights in institutions. The Act on Patients' Rights and Status of March 1st, 1993, served as the basis for this study. Of the Act, the patients' rights to good care and treatment, to information and to self-determination were discussed. The data were collected from six medical wards for long-term patients at a hospital and from an old people's home by using a questionnaire. Ninety relatives of demented patients participated in the study, the response rate being 60%. The data were analyzed statistically. The relatives stated that the right to good care and treatment was realized best. The right to information was fulfilled quite well according to the respondents. The fact that the staff would not give information on their own initiative was regarded as lack of information. The right to self-determination was realized most poorly; 44% of the respondents could not say whether their relatives were able to affect the care with their opinions and wishes, and 59% could not answer whether the patient could reject the care. On the contrary, the respondents preferred their own right to influence decision-making concerning the care. Pensioners who answered the inquiry were more satisfied with the fulfillment of the patients' rights than others when the three rights were discussed. However, children as relatives were more dissatisfied than other relatives with the fulfillment of the right to information and self-determination.

    Nb3Sn and other A15 members have been widely applied in nuclear power, nuclear magnetic reso-nance, and high-energy particle accelerators for their high critical current density (Jc) and upper critical field (Bc2). There have been comprehensive and intensive studies on the applications, the fundamental lattice dynamic and electronic properties, etc., of A15 superconductors. Various reviews on the preparations, structures, and properties have already been written in the last few years. Nevertheless, on account of the large amount of existing facts and views, a coherent view on the relations between the structures and properties has not appeared to unify the facts. This article sketches a multi-scale point of view on the relations between the multi-scale structures and the corresponding properties.

  11. Considerations on private human access to space from an institutional point of view

    Science.gov (United States)

    Hufenbach, Bernhard

    2013-12-01

    Private human access to space as discussed in this article addresses two market segments: suborbital flight and crew flights to Low Earth Orbit. The role of entrepreneurs, the technical complexity, the customers, the market conditions as well as the time to market in these two segments differ significantly. Space agencies take currently a very different approach towards private human access to space in both segments. Analysing the outcome of broader inter-agency deliberations on the future of human spaceflight and exploration, performed e.g. in the framework of the International Space Exploration Coordination Group, enables to derive some common general views on this topic. Various documents developed by inter-agency working groups recognise the general strategic importance for enabling private human access to space for ensuring a sustainable future of human spaceflight, although the specific definition of private human access and approaches vary. ESA has performed some reflections on this subject throughout the last 5 years. While it gained through these reflections a good understanding on the opportunities and implications resulting from the development of capabilities and markets for Private Human Access, limited concrete activities have been initiated in relation to this topic as of today.

    Full Text Available Opera has a famous history and even the present-day repertoire in opera houses mostly consists of classical and well-known works. Marketers are trying to find new ways that would enable opera lovers all over the world to enjoy top quality performances. One of the most successful models is real-time transmissions of operas to geographically remote cinemas. Cinemas from all around the world participate in the project. In this paper, the authors analyze the spectators´ profile and point out differences between North America and the Czech Republic, focusing on transmissions of performances by the Metropolitan Opera in New York. The authors submit a detailed analysis of the socio-demographic characteristics of the spectators and the attendance frequency. Special attention is paid to the marketing profile of Czech spectators, based on primary data gathered in the research. The paper is a combination of research report and business case study. The study reveals that female visitors prevail. Elderly people are also represented in high percentages. The spectators are characterized by refined taste in their lifestyles and familiarity with modern technology.

  13. Sediment Surface Areas, Organic Content, and Metal Fractionation of Point Mugu Sediments

    2002-12-01

    Point Mugu contains one of the largest coastal wetlands ecosystems in California, which includes a Naval Air station, several sewage oxidation ponds and a partly dredged lagoon. Remediation efforts include investigating the feasibility of using the present sewage pond sludge to restore a dredged area in the lagoon. A problem with this approach is the potential release and subsequent environmental impact of the toxic substances from the sludge. Contaminants may become unavailable once sorbed onto particles. In general, this process is a direct function of surface area and organic carbon sorbed onto the sediment. The goal of the current investigation is to provide insight into the biological availability of a suite of metal contaminants in Pt. Mugu marsh sediments by studying changes in the physical and chemical properties of the sediments at horizontal and vertical spatial scales. The surface area and organic carbon for eight cores were measured as well as the first three sequential extraction of a host of metals. We have found that a direct correlation exists between surface area and the organic content of sediments as a function of depth. Surface area and the amount of organic carbon decreases with depth, which could result in higher availability of metals with increasing depth into the sediments.

    Plant disease management faces ever-growing chalenges due to: (i) increasing demands for total, safe and diverse foods to support the booming global population and its improving living standards; (i) reducing production potential in agriculture due to competition for land in fertile areas and exhaustion of marginal arable lands; (ii) deteriorating ecology of agro-ecosystems and depletion of natural resources; and (iv) increased risk of disease epidemics resulting from agricultural intensiifcation and monocultures. Future plant disease management should aim to strengthen food security for a stable society while simultaneously safeguarding the health of associated ecosystems and reducing dependency on natural resources. To achieve these multiple functionalities, sustainable plant disease management should place emphases on rational adaptation of resistance, avoidance, elimination and remediation strategies individualy and colectively, guided by traits of speciifc host-pathogen associations using evolutionary ecology principles to create environmental (biotic and abiotic) conditions favorable for host growth and development while adverse to pathogen reproduction and evolution.

    The hydraulics of a thermal network of a district heating system is a very important issue, to which not enough attention is often paid. In this paper the authors want to point out some of the important aspects of the design and operation of thermal networks in district heating systems. The design boundary conditions of a heat distribution network and the requirements on active pressure - circulation pump - influencing the operation costs of the centralized district heating system as a whole, are analyzed in detail. The heat generators and the heat exchange stations are designed according to the design heat loads after thermal insulation, and modern boiler units are installed in the heating plant.

  16. Measurements on pointing error and field of view of Cimel-318 Sun photometers in the scope of AERONET

    Full Text Available Sensitivity studies indicate that among the diverse error sources of ground-based sky radiometer observations, the pointing error plays an important role in the correct retrieval of aerosol properties. The accurate pointing is specially critical for the characterization of desert dust aerosol. The present work relies on the analysis of two new measurement procedures (cross and matrix specifically designed for the evaluation of the pointing error in the standard instrument of the Aerosol Robotic Network (AERONET, the Cimel CE-318 Sun photometer. The first part of the analysis contains a preliminary study whose results conclude on the need of a Sun movement correction for an accurate evaluation of the pointing error from both new measurements. Once this correction is applied, both measurements show equivalent results with differences under 0.01° in the pointing error estimations. The second part of the analysis includes the incorporation of the cross procedure in the AERONET routine measurement protocol in order to monitor the pointing error in field instruments. The pointing error was evaluated using the data collected for more than a year, in 7 Sun photometers belonging to AERONET sites. The registered pointing error values were generally smaller than 0.1°, though in some instruments values up to 0.3° have been observed. Moreover, the pointing error analysis shows that this measurement can be useful to detect mechanical problems in the robots or dirtiness in the 4-quadrant detector used to track the Sun. Specifically, these mechanical faults can be detected due to the stable behavior of the values over time and vs. the solar zenith angle. Finally, the matrix procedure can be used to derive the value of the solid view angle of the instruments. The methodology has been implemented and applied for the characterization of 5 Sun photometers. To validate the method, a comparison with solid angles obtained from the vicarious calibration method was

    2012-01-01

    3D reconstruction of trees is of great interest in large-scale 3D city modelling. Laser scanners provide geometrically accurate 3D point clouds that are very useful for object recognition in complex urban scenes. Trees often cause important occlusions on building façades. Their recognition can lead to occlusion maps that are useful for many façade oriented applications such as visual based localisation and automatic image tagging. This paper proposes a pipeline to detect trees in poi...

  18. The Casimir Effect from the Point of View of Algebraic Quantum Field Theory

    2016-06-01

    We consider a region of Minkowski spacetime bounded either by one or by two parallel, infinitely extended plates orthogonal to a spatial direction and a real Klein-Gordon field satisfying Dirichlet boundary conditions. We quantize these two systems within the algebraic approach to quantum field theory using the so-called functional formalism. As a first step we construct a suitable unital ∗-algebra of observables whose generating functionals are characterized by a labelling space which is at the same time optimal and separating and fulfils the F-locality property. Subsequently we give a definition for these systems of Hadamard states and we investigate explicit examples. In the case of a single plate, it turns out that one can build algebraic states via a pull-back of those on the whole Minkowski spacetime, moreover inheriting from them the Hadamard property. When we consider instead two plates, algebraic states can be put in correspondence with those on flat spacetime via the so-called method of images, which we translate to the algebraic setting. For a massless scalar field we show that this procedure works perfectly for a large class of quasi-free states including the Poincaré vacuum and KMS states. Eventually Wick polynomials are introduced. Contrary to the Minkowski case, the extended algebras, built in globally hyperbolic subregions can be collected in a global counterpart only after a suitable deformation which is expressed locally in terms of a *-isomorphism. As a last step, we construct explicitly the two-point function and the regularized energy density, showing, moreover, that the outcome is consistent with the standard results of the Casimir effect.

  19. Robust seasonal cycle of Arctic sea ice area through tipping point in amplitude

    CERN Document Server

    Ditlevsen, Peter D

    2012-01-01

    The variation in the Arctic sea ice is dominated by the seasonal cycle with little inter-annual correlation. Though the mean sea ice area has decreased steadily in the period of satellite observations, a dramatic transition in the dynamics was initiated with the record low September ice area in 2007. The change is much more pronounced in the amplitude of the seasonal cycle than in the annual mean ice area. The shape of the seasonal cycle is surprisingly constant for the whole observational record despite the general decline. A simple explanation, independent of the increased greenhouse warming, for the shape of the seasonal cycle is offered. Thus the dramatic climate change in arctic ice area is seen in the amplitude of the cycle and to a lesser extend the annual mean and the summer ice extend. The reason why the climate change is most pronounced in the amplitude is related to the rapid reduction in perennial ice and thus a thinning of the ice. The analysis shows that a tipping point for the arctic ice area w...

  20. Cross-modal plasticity in sensory deprived animal models: From the thalamocortical development point of view.

    Science.gov (United States)

    Mezzera, Cecilia; López-Bendito, Guillermina

    2016-09-01

    Over recent decades, our understanding of the plasticity of the central nervous system has expanded enormously. Accordingly, it is now widely accepted that the brain can adapt to changes by reorganizing its circuitry, both in response to external stimuli and experience, as well as through intrinsic mechanisms. A clear example of this is the activation of a deprived sensory area and the expansion of spared sensory cortical regions in individuals who suffered peripheral sensory loss. Despite the efforts to understand these neuroplastic changes, the mechanisms underlying such adaptive remodeling remains poorly understood. Progress in understanding these events may be hindered by the highly varied data obtained from the distinct experimental paradigms analyzed, which include different animal models and neuronal systems, as well as studies into the onset of sensory loss. Here, we will establish the current state-of-the-art describing the principal observations made according to the time of sensory deprivation with respect to the development of the thalamocortical connectivity. We will review the experimental data obtained from animal models where sensory deprivation has been induced either before or after thalamocortical axons reach and invade their target cortical areas. The anatomical and functional effects of sensory loss on the primary sensory areas of the cortex will be presented. Indeed, we consider that the comparative approach of this review is a necessary step in order to help deciphering the processes that underlie sensory neuroplasticity, for which studies in animal models have been indispensable. Understanding these mechanisms will then help to develop restorative strategies and prostheses that will overcome the functional loss. PMID:26459021

    The breakup of the shearless invariant torus with winding number {omega}=2-1 is studied numerically using Greene's residue criterion in the standard nontwist map. The residue behavior and parameter scaling at the breakup suggests the existence of a new fixed point of the renormalization group operator (RGO) for area-preserving maps. The unstable eigenvalues of the RGO at this fixed point and the critical scaling exponents of the torus at breakup are computed.

  2. The pros and cons of cryogenic accelerators: An engineering point of view

    International Nuclear Information System (INIS)

    The design of cryogenic linacs is a challenging engineering task; however, significant improvements in accelerator performance are possible. Resistive power losses may be reduced by a factor of four or greater. Greater flexibility is possible in thermal management as a result of substantial increases in thermal conductivity for certain materials. Radio frequency structures may by an order of magnitude more stable in terms of frequency shifts due to thermal transients resulting form very small coefficients of thermal expansion at cryogenic temperatures. Significant engineering problems must be addressed, such as the design of effective rf contacts that will not be affected by thermal cycling and the design of cryogenic mechanisms and dynamic components, such as frequency tuners, that operate reliably at cryogenic operating temperatures. The areas of high-power sparking and multipactoring have not yet been experimentally addressed. Both Los Alamos, Grumman Aerospace Corporation, and Boeing Corporation have built or are building and testing cryogenic accelerator structures. This paper reviews the advances made in cryogenic technology applied to radio frequency quadrupole (RFQ) and drift tube linac (DTL) structures and will discuss the advantages and engineering challenges that these linacs present

  5. HOW TO SOLVE THE MORAL DILEMMA OF HELPING A FALLEN OLD MAN - FROM AN ECONOMIC POINT OF VIEW

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available In recent years, a peculiar phenomenon has happened time and time again and aroused hot social discussions in China. It is the fact that when an old man (or woman falls down on the street, most passers-by dare not to help him, or in other cases, when one of them does offer his (or her help, he might be accused of having knocked the old man down. As a result, nowadays in China, most people will not help a fallen old man for fear of being falsely accused. From an economic point of view, this paper points out that this peculiar phenomenon, which I call it a moral dilemma of helping a fallen old man, not only is a moral issue, but also closely relates to the intrinsic defects within China’s current institutions. In order to solve this moral dilemma, some improvement measures have to be taken not only in public moral education, but in the legal institutions, civil administration, health care system and public opinion guidance as well.

    Within the past decade, there has been a surge of interest in investigating the effects of clown intervention in a large variety of clinical settings. Many studies have focused on the effects of clown intervention on children. However, few studies have investigated clowning effects on adults. This paper presents an overview of the concept of medical clowning followed by a literature review conducted on the empirical studies drawn from three data bases (PubMed, PsycINFO, and Google Scholar), with the aim of mapping and discussing the evidence of clowning effects on non-children, namely adults. The following areas were investigated: Adult and elderly patients (mainly those with dementia), observers of clowning, namely non-hospitalized adults who are at the hospital as relatives of patients or health-care staff, and finally clowns themselves. The main results are that 1) clown intervention induces positive emotions, thereby enhancing the patient’s well-being, reduces psychological symptoms and emotional reactivity, and prompts a decrease in negative emotions, such as anxiety and stress; 2) clown doctors are also well-perceived by relatives and healthcare staff and their presence appears to be useful in creating a lighter atmosphere in the health setting; 3) few pilot studies have been conducted on clown doctors and this lacuna represents a subject for future research.

    Full Text Available Responding to institutional pressure to publish more papers, and in respected journals, management academics are seeking to increase their productivity by establishing co-authoring ties that speed up the process, from the initial stages of defining the research question to publication in a journal. Understanding the motives, benefits and hazards of co-authorship, especially using the experiences of highly reputed scholars, may help improve the efficiency and quality of research efforts. In this paper, we examine the responses to six questions sent to thirteen prolific international researchers, by email. In essence, we sought to understand such aspects as: the origins of co-authoring ties, the importance of having co-authors, the pitfalls of and methods for coordinating co-authorships, and what constitutes a contribution that warrants co-authorship. Results show that (1 international researchers evaluate their co-authorships positively, (2 many co-authorships emerge from prior supervision or personal proximity, more so than ties to the same institution, (3 the ordering of names is defined a priori and managed actively, (4 the benefits sought after are mainly specialization and complementary competences, (5 co-authorship is given based on actual contribution, albeit there are many forms of contribution, and (6 the pressure to publish, and an increasing difficulty of publishing in the top journals are the drivers of co-authorship. The analyses point to important insights for young Brazilian scholars.

  13. Unifying diseases from a genetic point of view: the example of the genetic theory of infectious diseases.

    Science.gov (United States)

    Darrason, Marie

    2013-08-01

    In the contemporary biomedical literature, every disease is considered genetic. This extension of the concept of genetic disease is usually interpreted either in a trivial or genocentrist sense, but it is never taken seriously as the expression of a genetic theory of disease. However, a group of French researchers defend the idea of a genetic theory of infectious diseases. By identifying four common genetic mechanisms (Mendelian predisposition to multiple infections, Mendelian predisposition to one infection, and major gene and polygenic predispositions), they attempt to unify infectious diseases from a genetic point of view. In this article, I analyze this explicit example of a genetic theory, which relies on mechanisms and is applied only to a specific category of diseases, what we call "a regional genetic theory." I have three aims: to prove that a genetic theory of disease can be devoid of genocentrism, to consider the possibility of a genetic theory applied to every disease, and to introduce two hypotheses about the form that such a genetic theory could take by distinguishing between a genetic theory of diseases and a genetic theory of Disease. Finally, I suggest that network medicine could be an interesting framework for a genetic theory of Disease.

    Focal segmental glomerulosclerosis (FSGS) is one of the primary glomerular disorders in both children and adults which can progress to end-stage renal failure. Although there are genetic and secondary causes, circulating factors have also been regarded as an important factor in the pathogenesis of FSGS, because about 40% of the patients with FSGS have recurrence after renal transplantation. Soluble urokinase-type plasminogen activator receptor (suPAR) is a soluble form of uPAR, which is a membrane-bound protein linked to GPI in various immunologically active cells, including podocytes. It has recently been suggested as a potential circulating factor in FSGS by in vitro podocyte experiments, in vivo mice models, and human studies. However, there have also been controversies on this issue, because subsequent studies showed conflicting results. suPAR levels were also increased in patients with other glomerular diseases and were inversely correlated with estimated glomerular filtration rate. Nevertheless, there has been no balanced review on this issue. In this review, we compare the conflicting data on the involvement of suPAR in the pathogenesis of FSGS and shed light on interpretation by taking into account many points and the potential variables and confounders influencing serum suPAR levels.

    Is it possible to establish (at short, medium and long term) future work conditions or expected work conditions for Colombian people considering upcoming work technologies? Is it possible to anticipate future work desirable work conditions for Colombian people in order to plan (foresee?) work technologies? These questions guided this research and they point to an action thesis and to a reaction one in this context of work crisis. Even though a work technology establishes where, when, how, who, who with, and using what element work is done, it also establishes certain work conditions. Besides, multiple forms of considering and deconstructing past have been created from many disciplines. However, in order to foresee or construct work technologies requires a different perspective for looking further. This research has been carried out considering other disciplines points of view regarding Future Studies and Future Thinking Studies. This research has the purpose of finding future paths for Future Thinking Studies from ergonomics point of view in this moment of global work crisis we are going through. PMID:23258752

    Full Text Available Construction is one of the highest contributing industries to occupational accidents by sector in Malaysia. Statistics have been drawn from year to year that show an increasing number of cases of accidents by industry sector. While it is impossible to completely eliminate all accidents, with a proper and effective safety and health policy or rules set by top management, especially contractors, the rate of accidents on construction sites can be reduced. The main objective of this study is to analyse the degree of application of the Occupational Safety and Health Act 1994 (OSHA 1994 in the construction industry and to identify the contributing factors leading to a lack of execution of OSHA 1994 on construction sites with a primary focus on contractors’ point of view. Five on-going construction projects in Perak were selected as case studies and site inspections were conducted. The results showed that none of the contractors have fully implemented the rules and regulations provided by the government. Within this report, some recommendations are made towards enhancing the safety and health issues on construction sites.

    Time-lapse microscopic movies are being increasingly utilized for understanding the derivation of cell states and predicting cell future. Often, fluorescence and other types of labeling are not available or desirable, and cell state-definitions based on observable structures must be used. We present the methodology for cell behavior recognition and prediction based on the short term cell recurrent behavior analysis. This approach has theoretical justification in non-linear dynamics theory. The methodology is based on the general stochastic systems theory which allows us to define the cell states, trajectory and the system itself. We introduce the usage of a novel image content descriptor based on information contribution (gain) by each image point for the cell state characterization as the first step. The linkage between the method and the general system theory is presented as a general frame for cell behavior interpretation. We also discuss extended cell description, system theory and methodology for future development. This methodology may be used for many practical purposes, ranging from advanced, medically relevant, precise cell culture diagnostics to very utilitarian cell recognition in a noisy or uneven image background. In addition, the results are theoretically justified. PMID:21879106

    In this paper we want to study the conditions in which we could bring a universe filled with different $Z_3$ vacua created during the Next to Minimal Supersymmetric Standard Model (NMSSM) electroweak symmetry breaking at $\\textit{O} (10)^2$ GeV and a three dimensional three states diluted Potts model together in the same universality class. Then we use Cardy-Jacobsen conjecture to prove that there might be a tri-critical point in the NMSSM electroweak epoch of early universe. We prove that due to the existence of this point there would be no cosmological domain wall problem. Moreover, at this point the heat capacity and correlation length diverge which lead to a huge amount of energy release at constant temperature and a new mechanism for cosmological structure formation. Also, the entropy decrease after the tri-critical phase transition could explain the problem of low initial entropy in early universe. Finally, we combine Cardy-Jacobsen and Yaffe-Svetitsky conjectures to show that there might be a tri-criti...

    -level spectroscopies to reveal the behaviour of adsorption and dissociation on ice. Additionally, pure ice and amine doped ice will be compared for their surface structure change at different temperatures, which will indicate the differences of surface disordering caused by different factors. For instance, we will have a chance to know better if impurities will cause local disordering, i.e. forming hydration shell, which challenges the traditional picture of a homogenous disordered doped ice surface. The findings of this study could not only improve our understanding of how acidic organics adsorb to ice, and of their chemical properties on ice, but also have potentials to know better the behaviour of pure ice at temperatures approaching to the melting point.

    2016-06-01

    The paper gives an overview on the problems occurring during commercial digital orthophoto (DOP) production. There is a wide variety in requirements on orthophotos. It is no problem to produce good orthophotos in small areas, whereas production of good and homogeneous orthophotos in large areas remains a challenge. Therefore, we discuss large area orthophotos based on regular areal flight with regular flight parameters and nadir images, not on large numbers of images creating orthophotos based on various oblique images. The focus of the paper is to optimize the process of line production of orthophotos to achieve the best results under minimum usage of resources. Beside improvements in commercial software, the improvement in process design can help to achieve this objectives. It is necessary the attach importance to the different quality aspects to invest the limited resources at the most profitable process step. The requirements on orthophotos can be grouped into three categories: geometric, radiometric and aesthetic requirements. The main intention is to generate correct and well interpretable orthoimages, putting attention to geometry and radiometry. Many requirements cause enormous expenditures in flight time, number of images and amount of interactive editing work. Among the geometric aspects, the accuracy is the prominent factor. The geometric quality of the underlying digital terrain model (DTM) is of outstanding importance. Depending on the used focal length during acquisition and overlap, geometric errors in the DTM are directly represented in the orthophoto. Particularly at manmade surface break lines, even horizontal DTM errors occur striking in the orthophotos. A special consideration is to put on objects outside the DTM surface. While buildings may be represented in a good manner in a digital surface models (DSM) to generate so called "true orthophotos", there is no way to represent vegetation, cables, poles etc. in an appropriate manner in any DSM

  16. Reduction of streamflow monitoring networks by a reference point approach

    Cetinkaya, Cem P.; Harmancioglu, Nilgun B.

    2014-05-01

    Adoption of an integrated approach to water management strongly forces policy and decision-makers to focus on hydrometric monitoring systems as well. Existing hydrometric networks need to be assessed and revised against the requirements on water quantity data to support integrated management. One of the questions that a network assessment study should resolve is whether a current monitoring system can be consolidated in view of the increased expenditures in time, money and effort imposed on the monitoring activity. Within the last decade, governmental monitoring agencies in Turkey have foreseen an audit on all their basin networks in view of prevailing economic pressures. In particular, they question how they can decide whether monitoring should be continued or terminated at a particular site in a network. The presented study is initiated to address this question by examining the applicability of a method called “reference point approach” (RPA) for network assessment and reduction purposes. The main objective of the study is to develop an easily applicable and flexible network reduction methodology, focusing mainly on the assessment of the “performance” of existing streamflow monitoring networks in view of variable operational purposes. The methodology is applied to 13 hydrometric stations in the Gediz Basin, along the Aegean coast of Turkey. The results have shown that the simplicity of the method, in contrast to more complicated computational techniques, is an asset that facilitates the involvement of decision makers in application of the methodology for a more interactive assessment procedure between the monitoring agency and the network designer. The method permits ranking of hydrometric stations with regard to multiple objectives of monitoring and the desired attributes of the basin network. Another distinctive feature of the approach is that it also assists decision making in cases with limited data and metadata. These features of the RPA approach

    Full Text Available Although mathematicians frequently use specialist software in direct teaching ofmathematics, as a means of delivery e-learning technologies have so far been lesswidely used. We (mathematicians insist that teaching methods should be subjectspecificand content-driven, not delivery-driven. We oppose generic approaches toteaching, including excessively generalist, content-free, one-size-fits-allpromotion of information and communications technology. This stance is fullyexpressed, for example, in the recent Teaching Position Statement from the LondonMathematical Society (2010 and is supported by a recent report from the NationalUnion of Students (2010, 5: “Not every area of study needed or was compatiblewith e-learning, and so to assume it would grant blanket advantages was notaccurate”. This paper is an attempt to explain mathematicians' selectivity in use ofinformation and communications technology and its guiding principles. The paperis addressed to our non-mathematician colleagues and is not intended to be a surveyof the existing software and courseware for mathematics teaching – the corpus ofexisting solutions is enormous and its discussion inevitably involves hardcoremathematics.

    The author has identified the following signficant results. A very distinct line representing the Ra-substage of the last deglaciation period is observable around the outer parts of the Oslo fjord. The moraine line is also traceable in some parts of the forest district on the Swedish side of the border forming part of the Central Swedish End Moraines. In the area of Lake Vanern to the southeast, the line is then again more distinct, partly due to the cultivation pattern. Outside the Central Swedish Moraine Line and nearer to the coast another not so distinct moraine line could be observed running NNW-SSE. This line crosses the coastline before reaching the Oslo fjord. Probably the moraine deposits on some outer islands in the fjord constitute part of this older moraine line. The study will be extended to districts of southern Sweden, where old moraine lines of the last deglaciation period are incompletely mapped.

  19. The science of conventional and water-cooled monopolar lumbar radiofrequency rhizotomy: an electrical engineering point of view.

    2014-01-01

    Radiofrequency ablation (RFA) is a safe and effective pain therapy used to create sensory dysfunction in appropriate nerves via thermal damage. While commonly viewed as a simple process, RF heating is actually quite complex from an electrical engineering standpoint, and it is difficult for the non-electrical engineer to achieve a thorough understanding of the events that occur. RFA is highly influenced by the configuration and properties of the peri-electrode tissues. To rationally discuss the science of RFA requires that examples be procedure-specific, and lumbar RFA is the procedure selected for this review. Adequate heating of the lumbar medial branch has many potential failure points, and the underlying science is discussed with recommendations to reduce the frequency of failure in heating target tissues. Important technical details of the procedure that are not generally appreciated are discussed, and the status quo is challenged on several aspects of accepted technique. The rationale underlying electrode placement and the limitations of RF heating are, for the most part, commonly misunderstood, and there may even need to be significant changes in how lumbar radiofrequency rhizotomy (RFR) is performed. A new paradigm for heating target tissue may be of value. Foremost in developing best practices for this procedure is avoiding pitfalls. Good RF heating and medial branch lesioning are the rewards for understanding how the process functions, attention to detail, and meticulous attention to electrode positioning.

    This article presents different theoretical elements that share some heterodox ideas. This elements reside in four intricate areas: rationality of the individual, the theory of prices, the kaleckian model of growth, and the integration of the real with the monetary sector. Despite the divergences, these theoretical elements constitute a coherent set that could be improved with the aim of building a sole heterodox theory,which would serve as a real alternative to the dominant neoclassical theory.

  1. Endocytic Trafficking of Membrane-Bound Cargo: A Flotillin Point of View

    Directory of Open Access Journals (Sweden)

    Melanie Meister

    2014-07-01

    Full Text Available The ubiquitous and highly conserved flotillin proteins, flotillin-1 and flotillin-2, have been shown to be involved in various cellular processes such as cell adhesion, signal transduction through receptor tyrosine kinases as well as in cellular trafficking pathways. Due to the fact that flotillins are acylated and form hetero-oligomers, they constitutively associate with cholesterol-enriched lipid microdomains. In recent years, such microdomains have been appreciated as platforms that participate in endocytosis and other cellular trafficking steps. This review summarizes the current findings on the role of flotillins in membrane-bound cargo endocytosis and endosomal trafficking events. We will discuss the proposed function of flotillins in endocytosis in the light of recent findings that point towards a role for flotillins in a step that precedes the actual endocytic uptake of cargo molecules. Recent findings have also revealed that flotillins may be important for endosomal sorting and recycling of specific cargo molecules. In addition to these aspects, the cellular trafficking pathway of flotillins themselves as potential cargo in the context of growth factor signaling will be discussed.

    A 40 ks \\emph{Chandra} ACIS-S observation of the dynamically young cluster A1367 yields new insights on X-ray emission from cluster member galaxies. We detect 59 point-like sources in the ACIS field, of which 8 are identified with known cluster member galaxies. Thus in total 10 member galaxies are detected in X-rays when three galaxies discussed in paper I (Sun & Murray 2002; NGC 3860 is discussed in both papers) are included. The superior spatial resolution and good spectroscopy capability of \\chandra allow us to constrain the emission nature of these galaxies. Central nuclei, thermal halos and stellar components are revealed in their spectra. Four new low luminosity nuclei (LLAGN) are found, including an absorbed one (NGC 3861). This discovery makes the LLAGN/AGN content in this part of A1367 very high ($\\sim$ 20%). Thermal halos with temperatures around 0.5 - 0.8 keV are revealed in the spectra of two elliptical galaxies NGC 3842 and NGC 3837, which suggests that galactic coronae can survive in cluster...

    Full Text Available Introduction: Measels, Mumps and Rubella (MMR are highly contagious infectious diseases which may lead to severe complications. These diseases are vaccine-preventable. The present Health Technology Assessment report (report on technological consequences, HTA report was commissioned by the German Institute of Medical Documentation and Information (DIMDI and addresses various aspects of the MMR vaccination, the key question being how the MMR immunisation coverage rate can be increased in Germany. Objectives: The objectives of this report were to describe the benefits of the MMR vaccination for Germany and to analyse how the desired MMR immunisation coverage of >95% can be achieved. Methods: A systematic literature search was performed in 29 literature data bases. Particularly for epidemiological data and information on vaccination programs, this systematic search was supplemented by an extensive hand search, written and oral enquiries, as well as interviews with experts. A total of 200 texts were used to prepare this report. Results: At 92.5% (as of 2004 based on the whole of Germany, the current immunisation coverage for measles in children is above the weighted EC-15-average of 90.67%. Statements can only be made regarding the probability of illness for measles, as no data is available for mumps and rubella. With 2.8 infections (per 100,000 residents in 2006, Germany has not achieved the WHO target. Of cases submitted to the laboratory, only 32% were validated by diagnostic laboratory findings and 45% confirmed clinical-epidemiologically. There are only few economic analyses of vaccination programs in Germany. In international publications, mainly measels are validated economically. An analysis of the cost of measles for Germany shows potential cost savings. Unfortunately, no complete economic evaluation (cost-effectiveness, cost-benefit, or cost-utility analyses for MMR vaccination has been performed for Germany. Analyses conducted in the US

  6. Transmutation of All German Transuranium under Nuclear Phase Out Conditions - Is This Feasible from Neutronic Point of View?

    Directory of Open Access Journals (Sweden)

    Bruno Merk

    Full Text Available The German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P&T could be considered as a technological option for the management of highly radioactive waste, therefore a wide study has been conducted. In the study group objectives for P&T and the boundary conditions of the phase out have been discussed. The fulfillment of the given objectives is analyzed from neutronics point of view using simulations of a molten salt reactor with fast neutron spectrum. It is shown that the efficient transmutation of all existing transuranium isotopes would be possible from neutronic point of view in a time frame of about 60 years. For this task three reactors of a mostly new technology would have to be developed and a twofold life cycle consisting of a transmuter operation and a deep burn phase would be required. A basic insight for the optimization of the time duration of the deep burn phase is given. Further on, a detailed balance of different isotopic inventories is given to allow a deeper understanding of the processes during transmutation in the molten salt fast reactor. The effect of modeling and simulation is investigated based on three different modeling strategies and two different code versions.

  7. Safety culture in a Belgian nuclear research centre from a social science point of view

    International Nuclear Information System (INIS)

    This paper is the result of a reflection within the framework of a Ph.D. research at SCK-CEN (Belgian Nuclear Research Centre) in collaboration with the University of Liege. The starting point of the work was the 'safety culture' model presented in the IAEA report 75-INSAG-4. This model is applied to the working organization of the SCK-CEN, also considering the safety culture as an open concept given its multi dimensionality. The methodology is based on three methods: observations, focus groups and interviews. The fieldwork was limited to two main installations: a research reactor, and a dismantling site. The preliminary findings are based on the data resulting from 4 Focus Groups. The most prominent components of a safety culture and the multiplicity of safety cultures in a large organization such as SCK-CEN will be discussed. (author)

    2008-01-01

    How is our gaze dispersed across the screen when watching television? An exploratory eyetracker study with a custom-designed show indicated a very strong center-of-screen bias with gaze points following a roughly normal distribution peaked near screen center. Examining the show across time revealed that people were rarely all looking at the same location, and the amount of gaze dispersion within frames was highly variable. Different forms of programming yielded different levels of dispersion: static network 'bumpers' created the tightest visual groupings, and gaze dispersion for frames with show content was less than the dispersion for commercials. Advertising frames with brand logos generated higher dispersion than the non-branded advertisement portions, and repeated advertisements generated higher dispersion than their first-run counterparts.

    A ferrule-based method of direct fs FBG inscription through protective plastic coating is demonstrated. Fluctuations of fiber core position relative to the writing fs beam are compensated by the developed auto-alignment system. As a result, high-quality FBGs with length from 0.1 to 50 mm are fabricated in polyimide-coated fibers, whose spectra are well described by the theory. The fabricated FBGs have great potential in sensor applications at high temperature and harsh environments both point-action and distributed ones. PMID:27464076

    Full Text Available Background & Objective: With the aim to clarify the rights of the patients on the basis of medical ethic norms, Patient Bill of Rights in five categories was developed in Iran for the first time, during 2002. The main objective of this study was to determine the views of patients, physicians and nurses about this aspect of medical ethics and its necessary to comply in Rasht public hospitals. Materials &Methods: In this cross-sectional study the data were collected by filling a reliable and validated questionnaire consisting of demographic part and 25 specific questions about the rights of patients, these questions were answered By 185 patients, 22 nurses and 14 doctors. Each of the criteria necessary to use was measured by the Likert scale from zero (completely disagree to five (fully agree. SPSS software 16 and one way ANOVA tests were used for data analysis. Result: The results showed that all groups were agreeing with the necessity to have a bill and consider the patient's rights during treatment (P<0.05. But the most controversial point were related to the rights of patient to have access to their information and the right to choose and decide (P<0.05. However, 68.2 percent of physicians, 80.05 percent of nurses, and 93 percent of patients were agreed with the Bill of Rights. Conclusion: Although all the groups were agreed with the patient's Bill of rights (P<0.05, It seems it is necessary to reconsider the issue of providing the necessary information to the patient and give attention to their choices and decisions by the medical health service providers.

  12. Anthropology from a Kantian point of view: toward a cosmopolitan conception of human nature.

    Science.gov (United States)

    Louden, Robert B

    2008-12-01

    Anthropology was a new field of study when Kant first began lecturing on it in 1772, and Kant himself was the first academic to teach regular courses in this area. As is well known, his own approach to anthropology is self-described as 'pragmatic', and Kant's pragmatic anthropology differs markedly from the anthropologies that other early contributors to the new discipline were advocating. In this essay I focus on a fundamental feature of Kant's anthropology that has been under-appreciated in previous discussions; namely, the particular conception of human nature that he believes anthropology, when pursued properly, leads to. I call this conception a cosmopolitan conception of human nature. In addition to establishing the central importance of this idea for Kant's project in anthropology, I also try in this essay to unravel some of its ambiguities and tensions as well as to highlight its underlying moral motives. The cosmopolitan conception of human nature that is central to Kant's anthropology is a further indication of the significance of his anthropology for ethics. PMID:19391369

    Use of ground based remote sensing technologies such as scanning lidar systems (light detection and ranging) has gained traction in characterizing ambient aerosols due to some key advantages such as wide area of regard (10 km2), fast response time, high spatial resolution (sources in agricultural and industrial settings. A suite of massbased and size distribution point sensors are used to locally calibrate the lidar. Generating meaningful particle size distribution, mass concentration, and emission rate results based on lidar data is dependent on strategic onsite deployment of these point sensors with successful local meteorological measurements. Deployment strategies learned from field use of this entire measurement system over five years include the characterization of local meteorology and its predictability prior to deployment, the placement of point sensors to prevent contamination and overloading, the positioning of the lidar and beam plane to avoid hard target interferences, and the usefulness of photographic and written observational data.

    Full Text Available Objective:Disease and hospitalization can be the first crisis that a child encounters. The aim of this study is to reveal a clear picture of the meaning of hospitalization in children, to show the experience and behavior of hospitalized children and to discover the meaning and understanding of hospitalization in them. Methods:This study is a phenomenology study of qualitative research within the framework of Husserl Eidetic phenomenology through comprehensive interviewing. The objective group consisted of children 7-11 years old and their parents hospitalized in the childrens ward of 22 Bahman Hospital and the surgery ward of 15 Khordad Hospital during the study (2008. Method of selection of participants was as follows: having experience of hospitalization, having ability to answer the questions, and being volunteered. Sample size was detected by data saturation. In the method of sampling, an object group of 20 (12 children and 8 parents were chosen and interviewed. The Seven Colaizzi Stages were used for analysis of data. Findings:The analysis of the interviews and the written narrations of the participants led to the extraction of 6 inner themes consisting of sickness, environment, reciprocal relationship, parents personal problems, mental and emotional matters and a spiritual dimension; all of which define a specific aspect of the experience of hospital in children and parents. Conclusion:The experience of hospitalization in children can be considered as a process of effort for returning to health and, on the whole, the regaining of the individuals status in the world. Nurses can ease this process by showing the importance of experience and feelings of individuals at the time of hospitalization and help people to adapt themselves to their new surroundings. This matter can enable the nurses to utilize methods of helping in the adaptation of individuals and thus guide the unique powers present in every individual to ease and quicken recovery.

  17. A bicategory of reduced orbifolds from the point of view of differential geometry

    2016-10-01

    We describe a bicategory (R ed O rb) of reduced orbifolds in the framework of classical differential geometry (i.e. without any explicit reference to the notions of Lie groupoids or differentiable stacks, but only using orbifold atlases, local lifts and changes of charts). In order to construct such a bicategory, we firstly define a 2-category (R ed A tl) whose objects are reduced orbifold atlases (on any paracompact, second countable, Hausdorff topological space). The definition of morphisms is obtained as a slight modification of a definition by A. Pohl, while the definitions of 2-morphisms and compositions of them are new in this setup. Using the bicalculus of fractions described by D. Pronk, we are able to construct the bicategory (R ed O rb) from the 2-category (R ed A tl) . We prove that (R ed O rb) is equivalent to the bicategory of reduced orbifolds described in terms of proper, effective, étale Lie groupoids by D. Pronk and I. Moerdijk and to the well-known 2-category of reduced orbifolds constructed from a suitable class of differentiable Deligne-Mumford stacks.

  18. Usefulness and perceived usefulness of Decision Support Systems (DSSs in participatory forest planning: the final users’ point of view

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available In recent decades, the focus of forestry Decision Support Systems (DSSs has expanded to consider the social dimension of forestry and to support participatory decision-making. A large number of models and tools have become available to solve forest management planning problems. The Usefulness of a DSS depends on the range of tools that it incorporates, and many researches have been developed to evaluate DSSs using Usefulness as parameter. The assessment of Usefulness concerns the effectiveness of a DSS. Furthermore, most assessments take into account the degree of Perceived Usefulness, which is considered an indicator of the impact a system has on job performance. The present study focuses on the analysis of final users’ point of view on the Usefulness and Perceived Usefulness of DSSs in participatory forest planning. The research investigates how forest users’ characteristics and context influence their views on the potentialities of DSSs to enhance both the various phases of the participatory planning process (Usefulness and job performance (Perceived Usefulness. The study is based on quantitative data collected through two questionnaires e-mailed to a sample of 150 DSSs end users. The questionnaires focused on Usefulness and on Perceived Usefulness topics, respectively. Results indicate that special attention must be given to motivating respondents with a clear explanation of the survey objectives when e-mailing questionnaires. Moreover, results show that, in general, respondents consider DSSs useful at each step of the participatory process, despite differences emerge among steps. The research also shows that respondents’ Perceived Usefulness of DSSs was higher before actually engaging with DSSs. Furthermore, the results highlight differences in Perceived Usefulness to improve job performance, suggesting that the use of DSSs may actually improve job performance more than expected. Specifically, results indicate that improving the

    Evaluation of neuroendocrine tumors extent comprises a somatostatin receptor scintigraphy with OctreoScan. This examination begins with the radiopharmaceutical preparation and its quality control (dose, visual appearance, radiochemical purity, ph). The radiopharmaceutical is administered intravenously at a slow rate with respect of the contra-indications and recommendations. The patient's good respect of low residue diet and digestive preparations is essential for a good imaging quality. In addition, the technologist's psychological role (particularly for people suffering from claustrophobia) and adequate procedures must be taken into account. Several days are necessary to perform the examination that comprises whole body and planar (thoracic and abdominal) views, combined SPECT-CT imaging. This hybrid modality using fused images allows a good anatomical localisation of focal areas of increased uptake even in case of faint uptake. Some false-positive can be avoided (colonic stasis, gall bladder). SPECT-CT contribution to the diagnosis is certain. (authors)

    Full Text Available This study claims that the financial problems existing in Turkish local administration which have been under reform by force of EU process have slight chance to be overcome. This is because like the reform efforts once tried in the 19th century Ottoman Empire, if the system would be reformed by transplanting the European system of city administration, the result could cause disappointment as it did in the Ottoman municipal 'revolution'. Rather, like European reformers did by 'inventing their traditions', Turkey could reform the local governments by reviving some of the institutions of classical cities which were evidently prosperous before industrialization.

    Nasal turbinate hypertrophy is a major cause of nasal airway obstruction that affects up to 20% of the European general population. This study aims to determine the efficacy of radiofrequency treatment as perceived by patients during a 2-years period. From 2007 to 2009, an observational study was conducted on 36 patients who consecutively underwent temperature-controlled radiofrequency tissue volume reduction. A questionnaire was administered to each patient in order to collect demographic data, lifestyle habits, health status and visual analogue scale (VAS) score of perceived symptoms. Mean VAS scores of nasal obstruction, headache, rhinorrhoea and anosmia after treatment were significantly lower than that at baseline. Urban residence and allergic rhinitis were significantly associated with lower mean improvement (2.9 vs. 5.6; P = 0.04 and 2.3 vs. 5.3; P = 0.01, respectively). A non significant association with scarce nasal obstruction improvement was present in older aged patients, in patients other than students and in active and passive smokers. Our data enrich the general knowledge on radiofrequency treatment of turbinate hypertrophy identifying the rate of long-term efficacy of radiofrequency treatment as perceived by patients and focusing on several risk factors involved in patient prognosis after treatment.

    Resource preservation is one of the main challenges in Europe, together with waste management and recycling; recently several researchers are interested in the recovering of critical raw materials and secondary raw materials from landfill. Aggregate supply, even if it is not "critical" sensus stricto (s.s.), is one of the European priorities (low value but high volume needs). On the other side, the management of quarry waste , mainly from dimension stones, but also as fines from aggregate crushing, is still a matter of concern. Such materials are managed in different ways both locally and nationwide, and often they are landfilled, because of an unclear legislation and a general lack of data. Most of time the local authorities adopt the maximum precaution principle or the enterprises find it little profitable to recover them, so that the sustainable recycling of such material is not valued. Several studies have shown, depending on the material specific characteristics, the viability of recycling quarry waste into new raw materials used in glass and ceramic industries, precast concrete production, infrastructures etc. (Loudes et al. 2012, Dino&Marian 2015, Bozzola et al 2012, Dino et al. 2012, etc.). Thus, aggregate production may be one of the profitable ways to use quarry waste and is falling under the priority of EU (aggregate supply). Positive economic and environmental effects are likely to be achieved by systematic recycling of quarry waste planned by industries (industrial planning) and public authorities (national and local planning of aggregate exploitation). Today, the recycling level varies to a great extent and systematic recovery is not common among European Countries. In Italy and Norway no significant incentives on recycling or systematic approaches for local aggregate exploitation exist. The environmental consequences can be overexploitation of the natural resources, land take for the landfills, environmental contamination and landscape alteration by

  10. A Proposed Area for Study of Accessory Section and Point of Terrestrial Permian-Triassic Boundary

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    After the establishment of the global stratotype section and point (GSSP) of the PermianTriassic boundary (PTB), the definition of the accessory section and point (ASP) of the terrestrial Permian-Triassic boundary (TPTB) is now on the agenda. However, all good TPTB sections so far known have the following shortcomings: (1) the exact TPTB horizon is difficult to define paleontologically with high-resolution, and (2) accurate correlation between marine and terrestrial PTBs is hard to attain. In order to enhance the understanding of the nature of the global life crisis in both the marine and terrestrial environments across the Paleozoic-Mesozoic transition, these shortcomings need to be addressed. In western Guizhou and eastern Yunnan, Southwest China, some fossiliferous PTB sections which include marine, paralic and terrestrial are well-developed, allowing bed-to-bed correlation of the PTB sequences.Fortunately, the marine PTB sequence in this area is almost the same as found at the Meishan Section,where the GSSP of the PTB is located, which may provide a reliable auxiliary marker for high-resolution demarcation of the TPTB. These features found in western Guizhou and eastern Yunnan make this area a good place to study the ASP of the TPTB, so we propose to study the ASP of the TPTB in this area.

  14. The Structure of the Solar Core: an Observer's Point of View

    Science.gov (United States)

    Appourchaux, T.

    Since the beginning of helioseismology, most of the internal and dynamics structure of the Sun has been revealed or so we thought. The last island where our powerful tools start to fail is the solar core, where nuclear reactions take place. With the advent of SOHO and GONG, we have now a quality of helioseismic data without precedence that should enable us to understand better the physics of the deepest solar regions. This goal can be partially achieved by measuring low-degree rotational splitting of p-modes, and by detecting the elusive g-modes. In a first part, I will review the fitting techniques that are being used for inferring the rotational splittings of low-degree p-modes. I will particularly focus on Fourier spectra fitting developped by Schou (1992) and refined by Appourchaux et al (1998). I will show how one can visualize from the data, the leakage matrix and how one can clean the data from the mode leakages. I will give examples of systematic errors introduced by the leakage matrix and by modes of aliasing degrees. I will also compare the Fourier spectra fitting technique to others techniques that use power spectra. I will give some recent results from SOHO and GONG. In a second part, I will report on the progress of the Phoebus group for detecting g-modes. The Phoebus group is composed of team members of BiSON, VIRGO and SOI/MDI. I will summarize some of the techniques we used for finding g-modes, and how one can use those for finding low-order low-frequency p-modes. I will, most probably, not report on g-mode detection but most likely stress that the future ahead of us is brighter than ever.

  18. Sources of uncertainty in relative sea-level change projections from a probabilistic point of view.

    Science.gov (United States)

    Jackson, Luke; Jevrejeva, Svetlana

    2016-04-01

    A number of relative sea-level change projections now exist in the literature that use a method of offline summation of individual components. This approach combines the projected ocean volume changes from an assimilation of ocean model outputs (e.g. CMIP5 archive) with ocean mass changes that are derived by normalising the present-day spatial fingerprint of each component (ice sheets, glaciers, land water storage) scaled by the global average projection for that component. At each stage of making the projections there are assumptions that will alter the uncertainty of the final result. For example, it is assumed that the distribution of ocean model outputs for projected dynamic sea-level change is Gaussian everywhere and the present-day pattern of ice-mass loss will continue throughout the century, neither of which is strictly the case. We quantify these sources of uncertainty to show how scenario dependency also plays a part in the projected uncertainty.

  19. On the origin of dislocation loops in irradiated materials: A point of view from silicon

    Science.gov (United States)

    Claverie, Alain; Cherkashin, Nikolay

    2016-05-01

    Numerous dislocation loops are often observed in irradiated and nuclear materials, affecting many physical properties. The understanding of their origin and of their growth mechanism remains unclear rendering all modeling efforts elusive. In this paper, we remind the knowledge which has been gained during the last 20 years on the formation and growth of extrinsic dislocations loops in irradiated/implanted silicon. From the compilation of a large number of experimental results, a unified picture describing the thermal evolution of interstitial defects, from the di-interstitial stable at room temperature, to "magic-size" clusters then to rod-like defects and finally to large dislocation loops of two types has emerged. All these defects grow by Ostwald ripening, i.e. by interchanging the interstitial atoms they are composed of, and transform from one to the other driven by the resulting reduction of the defect formation energy. A model has been proposed and is now integrated into process simulators which quantitatively describes the thermal evolution of all these defects, based on pertinent formation energies. The influence of the proximity of free surfaces or other recombining interfaces can be integrated, allowing simulating the possible dissolution of defects. It is suggested that, beyond silicon, the same type of scenario may take place in many materials. Dislocation loops are just one, easily detectable among many, type of defects which forms during the growth of self-interstitials. They do not nucleate but result from the growth and transformation of smaller defects.

    Highlights: • We used positron annihilation spectroscopy to study German RPV steels. • We examine microstructural changes in the studied specimens. • Simulation of neutron irradiation was performed by hydrogen ion implantation. • No large voids or vacancy clusters were formed due to irradiation or implantation. - Abstract: Commercial German reactor pressure vessel (RPV) steels were studied by positron annihilation lifetime spectroscopy (PALS). This unique non-destructive method can be effectively applied for the evaluation of microstructural changes and for the analysis of degradation of reactor steels due to neutron irradiation and proton implantation. Studied specimens of German reactor pressure vessel steels are originally from CARINA/CARISMA program. Eight specimens were measured in as-received state and two specimens were irradiated by neutrons in German experimental reactor VAK (Versuchsatomkraftwerk Kahl) in the 1980s. One of the specimens which was also in as-received and neutron irradiated condition was also used for simulation of neutron damage by hydrogen nuclei implantation. Defects with the size of about 1–2 vacancies with relatively small contribution (with intensity on the level of 20–40%) were observed in “as-received” steels. A significant increase in the size of the induced defects due to neutron damage was observed at a level of 2–3 vacancies in the irradiated specimens. The size and intensity of defects reached a similar level as in the specimens irradiated in nuclear reactor due to hydrogen ions implantation with energy of 100 keV (up to the depth <500 nm). This could confirm the ability to simulate neutron damage by ion implantation.

  1. PSA analysis focused on Mochovce NPP safety measures evaluation from operational safety point of view

    International Nuclear Information System (INIS)

    Mochovce NPP consists of four reactor units of WWER 440/V213 type and it is located in the south-middle part of Slovakia. At present first unit operated and the second one under the construction finishing. As these units represent second generation of WWER reactor design, the additional safety measures (SM) were implemented to enhance operational and nuclear safety according to the recommendations of performed international audits and operational experience based on exploitation of other similar units (as Dukovany and J. Bohunice NPPs). These requirements result into a number of SMs grouped according to their purpose to reach recent international requirements on nuclear and operational safety. The paper presents the bases used for safety measures establishing including their grouping into the comprehensive tasks covering different areas of safety goals as well as structural organization of a project management of including participating companies and work performance. More, results are given regarding contribution of selected SMs to the total core damage frequency decreasing.(author)

While the rainfall regime in the valley is relatively stable during the year, the thermal regime shows strong diurnal and seasonal variability. The hydrological regime of the main stream and its tributaries is dominated by snow and glacier melt, with high flow rates in summer and low flow rates in wintertime, when snowfalls accumulate on the ground. Water transfers from a compartment to another are particularly rapid, with flash floods having lag times of about 4 to 6 hours and significant sediment transport associated with liquid flow rates. Since 2014, a project involving local communities, stackeholders and researchers and aiming at understanding the flood generation processes and their evolution with climatic and environmental changes has been started. The project aims at characterizing the catchment behaviour from an integrated glacial-snow-hydrometeorological point of view and to develop a flood forecasting system for anticipate as much as possible a possible crisis and improve its management. As a part of this project and in the continuity of existing long-term measures in the valley (particularly within the GLACIOCLIM research observing system and the operational Météo-France frameworks) a new instrumentation network has been implemented in order to observe simultaneously the different components of the water cycle (atmospheric, hydrological, snow and glaciological variables) and their spatial, temporal and altitudinal gradients. We will present the instrumental network and the measurement strategy, as well as an analysis of the data collected during the 2014 and 2015 summers, which are quite contrasted from a

    The causal perturbation theory is an axiomatic perturbative theory of the S-matrix. This formalism has as its essence the following axioms: causality, Lorentz invariance and asymptotic conditions. Any other property must be showed via the inductive method order-by-order and, of course, it depends on the particular physical model. In this work we shall study the normalizability of the generalized quantum electrodynamics in the framework of the causal approach. Furthermore, we analyse the impli...

  6. Essence of Inviscid Shear Instability: a Point View of Vortex Dynamics

    Institute of Scientific and Technical Information of China (English)

    SUN Liang

    2008-01-01

    @@ The essence of shear instability is reviewed both mathematically and physically, which extends the instability theory of a sheet vortex from the viewpoint of vortex dynamics. For this, the Kelvin-Arnol'd theorem is retrieved in linear context, i.e., the stable flow minimizes the kinetic energy associated with vorticity. Then the mechanism of shear instability is explored by combining the mechanisms of both Kelvin-Helmholtz instability (K-H instability) and resonance of waves. The waves, which have the same phase speed with the concentrated vortex,have interactions with the vortex to trigger the instability. The physical explanation of shear instability is also sketched by extending Batchelor's theory. These results should lead to a more comprehensive understanding on shear instabilities.

  7. The first Step of Evolution from the View Point of chemical Catalysis

    Science.gov (United States)

    Parmon, V.; Snytnikov, V.

    A kinetic analysis of the steady state replication of molecules Xi due to consumption a "food" R via simple autocatalytic processes likekiktiR + Xi2Xi ,XiP,k -i and its more complicated analogs demonstrates inevitability of arising an irreversible and thus progressive evolution of autocatalyst molecules Xi , if only the autocatalysts can undergo a chemical mutation and the concentration of "food" R can fall below a critical valueRcri = k ti / k t . The natural selection of simple autocatalysts mimics a protolife and occurs in only one direction toward minimizing the value of Rcri which is improved through the mutation. The driving force of this selection is the long-term existence of a deficiency in "food" R. No doubt, this ability of simple autocatalytic systems to an irreversible progressive evolution is a total analogy of the existence of a primitive biological memory. This evidences in the possibility of starting a progressive prebiotic evolution even in the absence of special evolution information carriers like RNA or DNA molecules. One of the most plausible candidates for the first protolife autocatalytic reaction is the well-known "formosa" reaction of autocatalytic polymerization of formaldehyde into a variety of C3 -C6 monosaccharides in water solution catalyzed by the dissolved omnipresent calcium cations. Note, that formaldehyde was also a typical constituent of the Protoearth atmosphere. Mutation of saccharides is very easy and can be exemplified by any chemical modification of saccharide molecules, e.g., by nitrogen- or phosphate-containing derivatives, with the formation and progressive selection of initial biological building blocks. One may expect that the natural selection in abiogenous formosa systems could serve as a trigger of evolution mechanism. Also, formosa systems themselves may be a real precursor of appearance of the first and most primitive, but operating RNA molecules that resulted later in the first biological systems. Thus, the RNA or

    Full Text Available One of the most severe events occurring in critically ill patients admitted to a neonatal intensive care unit (NICU center is represented by the multiple organ failure (MOF, a systemic inflammatory response leading to a progressive organ dysfunction and mortality in newborns. MOF may occur in newborns primarily affected by multiple single organ diseases, including respiratory distress syndrome neonatal sepsis with acute kidney injury, post-asphyxial hypoxic-ischemic encephalopathy and pandemic influenza A (H1N1 infection. In a previous article from our group, based on the histological examination of all organs at autopsy of newborns affected by MOF, all organs studied did not escape to be damaged, including thymus and pancreas normally not mentioned in the literature of MOF. The aim of this article is to review the most important pathological changes pathologists should look for in every case of MOF occurring in the perinatal period, with particular attention to systemic endothelial changes occurring in blood vessels in all organs and sytems. On the basis of our experience, matching data during the last phases of the clinicopathological diagnosis represents a useful method, much more productive as compared to the method based on giving pathological answers to the clinical questions prospected before autopsy. As for the pathological features observed in neonatal MOF, one of them deserves a particular attention: the vascular lesions, and in particular the multiple changes occurring during MOF development in endothelial cells, ending with the loss of the endothelial barrier, probably the most relevant histological lesion followed by the insurgence of interstitial edema and disseminated intravascular coagulation. Small vessels should be observed at high power, with particular attention to the size and shape of endothelial nuclei, in order to evidence endothelial swelling, probably the initial modification of the endothelial cells leading to their

    Full Text Available As a universal human phenomenon, religion is rooted in human nature, and human beings instinctively require a superior and supreme power. Besides this internal need for religion, attention to the meaning, function, and interpretation of religion has always been prevalent in the history of human thought from West to East, and scholars have always tried to comment on and analyze this fundamental issue of human life .  From among the approaches that arose about the interpretation and explanation of religion, rationalism tendency—influenced by evolution—has stood up because in the establishment of religion, rationalism takes its genesis and evolution as manifestations of the evolution of human thought, and it takes the development and evolution of religion as equal. This approach considers religion as answer to the need of the cognitive need of human beings. In this anthropological approach, religion is the product of primitive human beings’ effort to identify objects and events in the surrounding environment. As a results, as the man’s knowledge of the world around him increases, the need for religion decreases .  Anthropologist like Edward Tylor and James Frazer have taken this view to the origin and evolution of religion. They emphasize on principles such as the bodily and cognitive unity of the mind, the survival principal, and the evolutionary intellectual pattern of human beings in order to interpret religion stages from animism and magic till monism and monotheism, which will eventually decline during the development of science .  Taylor regards anthropology as the best scientific method to achieve a universal theory to understand the origin of religion. Based on its psychological unity, religion in all times and places—despite its diversity—is a unique phenomenon and has an exclusive identity because the very existence of commonalities in all practices and customs of the people of the world is indicative of the basic

    The collapse and spreading of granular columns has been the subject of sustained interest in the last years from both mechanical and geophysical communities. Yet, in spite of this intensive research, the adequate rheology allowing for a reliable continuum modeling of the dynamics of granular column collapse is still open to discussion. Essentially, continuum models rely on shallow-water approximation for which dissipation and sedimentation processes are taken into account through the introduction of ad hoc laws. However, the rheological origin of the experimental scaling laws exhibited by the granular columns when spreading remains unclear. On these grounds, we adopt an alternative approach consisting of studying the collapse of columns of material obeying a Bingham rheology. Therefore we carried out series of numerical simulations using the Gerris Flow Solver solving the time dependent incompressible Navier-Stokes equation in two dimensions for the specified rheology. We first check that the mass exhibit similar scaling laws as those shown by granular columns. Then we investigate in which extent rheological parameters do reflect on these scaling laws. A comparative analysis of Bingham and granular flow characteristics ensues.

    Full Text Available Understanding the problems faced by rural extension in Uruguay as well as the conceptions used by the development agents to conduct their practices constitutes a contribution to both, the Uruguayan rural development policies and the wider space of the MERCOSUR. A quali-quantitative research was conducted, during which 32 Uruguayan extensionists replied to a questionnaire. Replies underwent content and statistic analysis. Results suggest that the Uruguayan rural extensionists posses a complex conception of their practice, which articulates productive and social dimensions and relates to a critical and participatory way of understanding rural extension. Nevertheless, a diffusionist conception of rural extension is also present in some cases. Finally, problems related to group dynamics are highlighted.

  20. Evolutionary Implications of Metal Binding Features in Different Species’ Prion Protein: An Inorganic Point of View

    Directory of Open Access Journals (Sweden)

    Diego La Mendola

    2014-05-01

    Full Text Available Prion disorders are a group of fatal neurodegenerative conditions of mammals. The key molecular event in the pathogenesis of such diseases is the conformational conversion of prion protein, PrPC, into a misfolded form rich in β-sheet structure, PrPSc, but the detailed mechanistic aspects of prion protein conversion remain enigmatic. There is uncertainty on the precise physiological function of PrPC in healthy individuals. Several evidences support the notion of its role in copper homeostasis. PrPC binds Cu2+ mainly through a domain composed by four to five repeats of eight amino acids. In addition to mammals, PrP homologues have also been identified in birds, reptiles, amphibians and fish. The globular domain of protein is retained in the different species, suggesting that the protein carries out an essential common function. However, the comparison of amino acid sequences indicates that prion protein has evolved differently in each vertebrate class. The primary sequences are strongly conserved in each group, but these exhibit a low similarity with those of mammals. The N-terminal domain of different prions shows tandem amino acid repeats with an increasing amount of histidine residues going from amphibians to mammals. The difference in the sequence affects the number of copper binding sites, the affinity and the coordination environment of metal ions, suggesting that the involvement of prion in metal homeostasis may be a specific characteristic of mammalian prion protein. In this review, we describe the similarities and the differences in the metal binding of different species’ prion protein, as revealed by studies carried out on the entire protein and related peptide fragments.

  1. Improvement of logistics education from the point of view environmental management

    Bányai, Á.

    2009-04-01

    The paper briefly presents the influence of environmental management on the improvement of the logistics education and research structure of the Department of Materials Handling and Logistics at the University of Miskolc, Hungary. The logistics, as an integrated science offers a very good possibility to demonstrate the effect of new innovative knowledge on the migration of the priorities of education and research of sciences. The importance of logistics in the field of recycling (or in wider sense in the field of environmental management) can be justified by the high proportion of logistic costs (as investment and operation costs) and these costs show that optimum logistic solutions are able to decrease the financial outcomes and lead to the establishment of a profitable system. Technological change constantly creates new demands on both education and research. The most important objective of the department is to create a unique logistics education in the country. For this reason the department offered up-to-date integrated knowledge at all level: undergraduate, master degree and PhD education. The integration of logistics means traditionally the joint use of technology of material handling, method of material flow, technology method of traffic, information technology, management sciences, production technology, marketing, market research, technology of services, mathematics and optimization, communication technology, system engineering, electronics and automation, mechatronics [1, 3]. The education and research portfolio of the department followed this tradition till 1993. The new lectures in the field of sustainability (logistics of recycling, logistics of quality management and recycling, closed loop economy, EU logistics or global logistics) became more and more important in the logistics education. The results of fast developments in closed loop economy, recycling, waste management, environmental protection are more and more used in the industry and this

  2. Production of heavy water. An analysis from export control point of view

    International Nuclear Information System (INIS)

    The main use for heavy water is in heavy water moderated nuclear reactors. This type of reactor is optimal for producing plutonium and therefore countries with nuclear weapons ambitions show interest for such reactors. Most equipment used in heavy water production facilities are under export control to prevent clandestine heavy water production. Heavy water is produced by increasing the concentration of deuterium in the water relative to natural hydrogen. For use in nuclear reactors the deuterium content has to be increased from 0,0155 % to more than 99,75 %. The enrichment can be achieved by several different processes where the GS-process (hydrogen-sulphide exchange) and ammonia-hydrogen exchange process are the two most cost efficient. The energy consumption for these processes is however relatively high. This is due to low separation efficiency which is caused by the relatively small difference in chemical properties between heavy water and natural water. FOI has, under contract work financed by SKI, performed a study of different production processes for heavy water and identified equipment used in the processes. The identified equipment includes both equipment under export control and other sensitive equipment which is important to prevent countries with nuclear weapons ambitions to acquire

    1988-01-01

    We show that the notion of ''preconditioning'' from linear algebra can provide a framework for the discussion of algorithms for the numerical solution of the transport equation. In this context we show that the conjugate gradient method yields substantial savings over the Neumann series solution of the standard integral formulation of the transport equation for optically thick regimes. Further, we show that the diffusion synthetic acceleration (DSA) algorithm is the Neumann series solution of the standard integral formulation of the transport equation preconditioning by the Green's function of a diffusion operator. The preconditioned conjugate gradient method, using DSA as a preconditioner, again yields substantial savings. 12 refs., 3 figs., 2 tabs.

    2012-10-01

    Full Text Available There are increasing challenges among the elderly in the Arctic region. Global warming due to climate change is one of the major reasons for these challenges. Because of climate change temperature in the region increases, which results in rapid melting of sea ice causing various environmental, social, cultural and economic problems. Population in the region suffers from these problems where elderly people are the most vulnerable. Climate change has already affected the elderly lives in different ways, such as, by physical, social, political, cultural and psychological ways. These have serious consequences in terms of human rights of this vulnerable group of people. However, the elderly people’s human rights issues have not been adequately researched in the context of this region. The goal of this paper is to present elderly related human rights issues, particularly the rights that are affected due to climate change in this specific region.

    Full Text Available Forgery by its nature, always harms the trust that people are forced to have and need to grant one another in the relations among themselves or which they should show for the things usually considered as the expression and evidence of truth. While for the offenses committed by violation of trust, this is the rule applied intuitu personae, taking into account the personal condition of the person to whom trust is granted, in forgery crimes trust is given in rem, meaning to the thing per se perceived as being the expression of truth. Thus, we are not in front of a violation of trust given to certain people, but in front of the trust granted to the thing which is assumed legally the characteristic of expressing the truth, but truth which has been altered. This paper aims to be an interdisciplinary approach, starting from the criminological meaning rendered to public trust and up to its legal effects produced, set into criminal or extra-criminal content, an approach derived from applying the method of observation.

This applies in particular, if the ontology to be visualized is based on a large text corpus that comprises a huge number of concepts, relations and annotations. In SNIK, we developed such an ontology of information management in hospitals in order to support the transfer of knowledge in the context of the university education. The challenge is to identify tools and methods, which are capable to support ontology visualization and usage as efficiently as possible. Related research fields (e.g. bioinformatics) are confronted with similar visualization problems. These tools and methods used could provide a suitable solution in our research field. In total, we assessed eight tools concerning the visualization of large ontologies to evaluate their suitability representing knowledge in the field of medical informatics.

    In later years scientists have taken increased interest in understanding wood ultrastructure, but with limited emphasis on close molecular relationships of its polymers. This aspect is examined from the Hansen solubility parameter concept and from the requirement that contacts between wood polymers...... yields consistent solubility parameters for the key wood components. Lignin and cellulose are not compatible. Cellulose regions and backbones of hemicelluloses are compatible to a degree. Some hemicellulose segments with hydroxylated side groups are expected to orient themselves towards cellulosic...... regions, whereas segments, e.g. with acetylated side groups, orient themselves towards lignin regions, in both cases by virtue of similarity of their local solubility parameters.

Because of that there has been a greater acceptance of qualitative methods and with that also the value of employing phenomenological approaches in the academic discipline of sport psychology has increased in recent years. Phenomenological psychology can allow us to look more closely to athletes’ experiences and therefore plays a mediating role between applied and theoretical aspects of sport psychology. We find its special importance at phenomena connected to peak performance and different stages of consciousness.

  14. Assessing the Metabolic Diversity of Streptococcus from a Protein Domain Point of View.

    Directory of Open Access Journals (Sweden)

    Edoardo Saccenti

    Full Text Available Understanding the diversity and robustness of the metabolism of bacteria is fundamental for understanding how bacteria evolve and adapt to different environments. In this study, we characterised 121 Streptococcus strains and studied metabolic diversity from a protein domain perspective. Metabolic pathways were described in terms of the promiscuity of domains participating in metabolic pathways that were inferred to be functional. Promiscuity was defined by adapting existing measures based on domain abundance and versatility. The approach proved to be successful in capturing bacterial metabolic flexibility and species diversity, indicating that it can be described in terms of reuse and sharing functional domains in different proteins involved in metabolic activity. Additionally, we showed striking differences among metabolic organisation of the pathogenic serotype 2 Streptococcus suis and other strains.

  15. Essence of inviscid shear instability: a point view of vortex dynamics

    CERN Document Server

    Sun, L

    2006-01-01

    The essence of shear instability is fully revealed both mathematically and physically. A general sufficient and necessary stable criterion is obtained analytically within linear context. It is the analogue of Kelvin-Arnol'd theorem, i.e., the stable flow minimizes the kinetic energy associated with vorticity. Then the mechanism of shear instability is explored by combining the mechanisms of both Kelvin-Helmholtz instability (K-H instability) and resonance of waves. It requires both concentrated vortex and resonant waves for the instability. The waves, which have same phase speed with the concentrated vortex, have interactions with the vortex to trigger the instability. We call this mechanism as "concentrated vortex instability". The physical explanation of shear instability is also sketched. Finally, some useful criteria are derived from the theorem. These results would intrigue future works to investigate the other hydrodynamic instabilities.

    In its 12 years of successful running, the HERMES experiment has addressed all aspects in studying the spin structure of the nucleon by measuring not only inclusive but also semi-inclusive and exclusive processes in deep-inelastic lepton scattering. Novel and pioneering results on the spin structure of the nucleon are presented which illustrate the new trends in the field. We concentrate here on the quark spin flavour decomposition of the nucleon spin, the extraction of the gluon polarisation and on novel transverse spin phenomena. The new formalism of Generalised Parton Distributions and their investigation in hard exclusive processes is discussed elsewhere at this workshop [M. Dueren, Hard exclusive reactions and Generalised Parton Distributions at HERMES, proceedings to this Workshop].

  18. Women's health from a woman's point of view: a review of the literature.

    Lempert, L B

    1986-01-01

    The literature on the current health problems of women is reviewed, clarifying the conditions and updating present knowledge of women's health within the context of medical and social research. Both medical professionals and women have begun to address women's health issues with 4 major issues receiving particular emphasis: the charge that physicians fail to take women's complaints seriously; the allegation that the population of women is being drugged; the accusation that women experience excessive surgical procedures; and the notion that sexism is inherent in American medical education. Focus on these issues is not the answer. Women, individually and collectively, need to clarify issues of women's health within the context of modern research and understanding. The literature is reviewed in the categories of prepubescent females, adolescence and the young woman, women's reproductive lives, life styles of the middle years, external and internal abuse, and aged women. The estimated annual occurrence of 60,000-100,000 cases of incest and/or sexual abuse among prepubescent females makes it a women's health issue of serious dimension. The victims are overwhelmingly female with a ratio of 10 females to 1 male child. Appetite disorders, known as patharexia, are a major public health problem of female adolescents. After depression, they represent the most common emotional illness among young girls and women. Anorexia nervosa, bulimarexia, and bulimia all are characterized by body image and distortion and the victim's obsessive desire to be thin. A more conforming, but still inappropriately adapted, response to social expectations for women is teen pregnancy. Teenagers who decide to have their babies often are those with the fewest options. Voluntary childlessness, late age childbirth, and issues of reproductive freedom are having social, political, and economic impact on the lives of all women. The prevailing social context of sexism and inequality contributes to the

  20. Humour Theories and the Archetype of the Trickster in Folklore: An Analytical Psychology Point of View

    2012-04-01

    Full Text Available Humour theories describe different parts of humour as a phenomenon, obtained on the personal and community level, so difficult to be explained. The analytical psychology of Carl Gustav Jung may help in the explanation of why the search for the “Holy Grail of Humour” is as if trying to catch a shadow. The archetype of the trickster in folklore may help us describe some common and different parts of the universal phenomenon of humour and the specific ethno-psychological traits.The paper presents an overview of basic humour theories, supported by analytical psychology comments, the archetype of the trickster in Bulgarian and Russian folklore, in the folklore of Native American tribes, Kalevala and Edda (Snorri Sturluson with an attempt to explain how the traits of this “hero” provide a list of the components making something humorous for different people and what are the common traits that can be described as universal.This overview could help trace the humour phenomenon from the universal, through the community, to the individual level trying to find how important this is in searching for its characteristics.

  1. [Breast cancer and pregnancy: decision making and the point of view of the mother].

    Science.gov (United States)

    Eisinger, François; Noizet, Agnès

    2002-09-01

    For the treatment of breast cancer, modifications of decision making related to pregnancy could be assessed through three questions. Why a decision had been chosen? In that case, the hypothesis is that decisions are based on the expected utility. The theory assumes weighting and computation of complete possibilities with their associated probabilities and values. However values exhibits a wide inter-individual variation range. Therefore the predictability of choice based on this model is indeed very low. Furthermore it is likely that the willingness of pregnancy after breast cancer contains besides classic constituents of appeals of motherhood, a specific meaning of recovery both of health and femininity. The second question: who is in charge of the decision? And under the paradigm of autonomy, women' decision is, merely by itself, the right decision. The last question is how? For some situations for which foreseeing is quiet complex, the value of the process in itself is increased and could help the end-oriented or self-determined decision. Casuistic analysis could therefore improve women' decisions. The issue is not only about decision but also related to patient-physician relationship, about an issue that is not only a biomedical problem. PMID:12368126

    Human health condition can be estimated only using adaptive responses theory. We include overactivation responses and incomplete adaptation in addition to stress reactions in the distress-group. Quiet and raised activation reactions were included into the eustress-group. All health spectrum should be divided in three groups. For health persons: 1) physiologic standard = safe health level = eustress reactions of high reactivity level 2) prenosological conditions = eustress reactions of low reactivity level, orientation, 3) premorbid conditions = adaptation mechanism breaking = distress reaction. For patients: 1) auspicious course of the disease = complete remission = eustress reactions of high reactivity level, 2) indefinite course of the disease = partial remission = eustress reactions of low reactivity level, orientation, 3) severe course of the disease = absence of remission = unfavorable prognosis = distress reaction.

    Dengue is a serious infectious disease and a growing public health problem in many tropical and sub-tropical countries. To control this neglected tropical disease (NTD), vaccines are likely to be the most cost-effective solution. This study analyzed dengue vaccines from both a historical and longitudinal perspective by using patent data, evaluating the geographic and time coverage of innovations, the primary patent holders, the network of cooperation and partnership for vaccine research and development (R & D), the flow of knowledge and the technological domain involved. This study can be seen as an example of the use of patent information to inform policy discussions, strategic research planning, and technology transfer. The results show that 93% of patents were granted since 2000, the majority belonging to the United States and Europe, although the share of patents from developing countries has increased. Unlike another NTDs, there is great participation of private companies in R & D of dengue vaccines and partnerships and collaboration between public and private companies. Finally, in this study, the main holders showed high knowledge absorption and generated capabilities. Therefore, this issue suggests that to overcome the difficulty of translational R & D it is necessary to stimulate the generation of knowledge and relevant scientific research, to enable the productive sector to have the capacity to absorb knowledge, to turn it into innovation, and to articulate partnerships and collaboration.

  11. Volumetric and transport properties in microemulsions and the point of view of percolation theory

    Mehta, S. K.; Bala, Kiran

    1995-06-01

    Microemulsions have been prepared from either benzene, toluene, ethylbenzene, or o-xylene and water using a mixture of surfactants of Span 80 and Tween 20 in the volume ratio of 1:4. These formulated microemulsions having propanol as the cosurfactant have been characterized by measuring their dynamic properties, i.e., conductance σ, density ρ, viscosity η, and ultrasonic velocity u, as a function of the volume fraction of water φ at 30 °C. The conductance values change exponentially as the volume fraction of water is increased. The use of a percolation model gives reasonable agreement between the experimental and calculated values. The viscosities vary in a nonmonotonic way, giving two peaked plots when the water content increases, indicating a lack of correlation with conductivity. The ultrasonic velocity and isentropic compressibility KS data throw some light on structural changes that occur in the microemulsion. An attempt has also been made to calculate the density ρm and isentropic compressibility KS,m of the micellar phase from the experimental data. The results indicate a trend toward an enhanced waterlike character of the dispersed phase at a high volume fraction of water φ.

    Full Text Available Introduction: Problem based learning (PBL has developed all over the world and this educational strategy is being used in many universities. Due to some problems in its classic form, it was difficult to use conventional PBL in Shahroud university of medical sciences (SHMU. Researchers conducted a modified form of PBL. Methods: In this study, 31 students by the subject of nursing in respiratory diseases with 1.5 credits were asked to reflect their idea in regard to a new method of teaching and modified problem based learning (MPBL. Results: The results of this study indicated that in MPBL students had tendency and good motivation toward more clinical and applied part of the subject. 77.4% of subjects have satisfaction from MPBL. Conclusion: Based on the findings of this study, we concluded that advantages of MPBL to PBL are as fallow: 1- In PBL the tutor is less active but in MPBL the tutor plays a more active role in process of teaching and feels more effectiveness. 2- There is no need to assign many tutors in each class. 3- More students can be taught in a shorter period of time. 4- MPBL is not expensive and dose not imposes financial load to administrative system

    2015-08-15

    For a deep storage of radioactive waste geologists gave their preference to salt prior to other rock complexes such as clay or granite. Major deposits from pure rock salt are particularly suitable to safely seal radioactive wastes from the biosphere because due to their plasticity they are free from fissures in which liquids and gases could circulate and because their thermal conductivity is higher than of other rocks. The geological stability of salt domes can be shown by their geological evolution. Thus the salt dome in Gorleben was formed 100 million years ago and is older than the Atlantic, the Alps or the ascent of the low mountain range. During this long period it survived ocean floods, mountain formations, earthquakes, volcanism and ice ages without considerably changing its shape. There are no geological reasons, why it should not remain stable during the next million years.

    The hodograph of the Kepler-Coulomb problem, that is, the path traced by its velocity vector, is shown to be a circle and then it is used to investigate other properties of the motion. We obtain the configuration space orbits of the problem starting from initial conditions given using nothing more than the methods of synthetic geometry so close to Newton's approach. The method works with elliptic, parabolic and hyperbolic orbits; it can even be used to derive Rutherford's relation from which the scattering cross section can be easily evaluated. We think our discussion is both interesting and useful inasmuch as it serves to relate the initial conditions with the corresponding trajectories in a purely geometrical way uncovering in the process some seldom discussed interesting connections.

    Full Text Available Robotic surgery (RS technology has undergone rapid growth in the surgical field since its approval. In clinical practice, failure of robotic procedures mainly results from a surgeon’s inability or to a device malfunction. We reviewed the literature to estimate the impact of this second circumstance in RS and its consequent legal implications. According to data from the literature, device malfunction is rare. We believe it is necessary to complement surgical training with a technical understanding of RS devices.

    I propose a novel heuristic method for the deconfinement of quarks. It proceeds in two phases. Firstly, a frozen hydrogen pellet is inertially confined by the ultra-intense lasers up to a solid state density. Secondly, a solid state nano-pellet is ``punched'' by a femtosecond TeV-photon beam created in the beat wave driven free electron laser (BW-FEL), leading to the ``rapture'' (in a ``karate chop'' model) of the ``MIT Bag'' before the asymptotically free quarks move apart. The threshold ``rapture force'' of the TeV photon is 10^8N. M. Gell-Mann. The Quark and the Jaguar: Adventures in the Simple and the Complex (New York, NY: W.H. Freeman and Co., 1994) [cf. M.

    Detection of point-source gamma signals from aerial measurements is complicated by widely varying terrestrial gamma backgrounds, since these variations frequently resemble signals from point-sources. Spectral stripping techniques have been very useful in separating man-made and natural radiation contributions which exist on Energy Research and Development Administration (ERDA) plant sites and other like facilities. However, these facilities are generally situated in desert areas or otherwise flat terrain with few man-made structures to disturb the natural background. It is of great interest to determine if the stripping technique can be successfully applied in populated areas where numerous man-made disturbances (houses, streets, yards, vehicles, etc.) exist.

    Full Text Available There is now extensive proof that high percentage of mammographic density (MD is an independent risk factor for breast cance.r Taking this into account, the research data are summarized with regard to relation of MD to anthropometric, as well as hormonal, genetic and genotoxic factors. There is a negative correlation between MD and such risk factors as age, number of deliveries, BMI and waist-hip ratio. Most inves- tigations show a direct connection between MD and prolactin level or insulin-like growth factor in blood, mostly in premenopaus al women. Relations of MD with blood estrogens, testosterone, sex hormone binding globulin prove to be too diverse to be taken in account of. It is pos- sible that the action of hormones, especially estrogens, is mediated through their metabolites catecholestrogens and / or reactive oxygen spe- cies. There is certain evidence that a genetic component plays a role in MD. It refers to COMT Val158Met, IGF-I rs6220 A> G and UGT1A1 in premenopausal women, and to ESR1 (XbaI и PvuII in menopausal cases.Although it is obvious that the risk of breast cancer related to MD is brought about by many factors, there is a necessity for studying addi- tional criteria modifying the process, as well as for searching means for preventing it.

    2012-01-01

    Full Text Available Background and Objectives: Pigs offer an unlimited source of xenografts for humans. The use of transplants from animal origin offers a potential solution to the limited supply of human organs and tissues. However, like many other mammalian species, pigs harbor porcine endogenous retrovirus (PERV, which are encoded in their genomic DNA and are assumed to have been integrated into the porcine germ line more than 7.6 × 106 years ago and showing that the age correlates with the time of separation between pigs and peccaries 7.4 × 106 years ago. The ability of the PERV to infect human cells in vitro has heightened safety concerns regarding the transmission of PERV to pig xenograft recipients. In this study, we detected PERV-AC recombinant virus in porcine genomic DNA that may have resulted from exogenous viral recombination. Infectious risk in xenotransplantation will be defined by the activity of PERV loci in vivo. We identified unique Haemophilus aegyptius III HaeIII gag restriction fragment length polymorphism (RFLP profiles resulting from single nucleotide polymorphisms; these were found only in animals that produced human tropic PERV. Materials and Methods: Porcine tissues were analyzed using validated assays specific for PERV: polymerase chain reaction (PCR (for PERV DNA, RT-PCR (for PERV RNA, cell culture, RFLP analysis, and sequence analysis. Conclusions and Interpretation : These findings have demonstrated that the presence of both DNA and RNA forms of porcine endogenous retrovirus in porcine tissues needs to be carefully considered when the infectious disease potential of xenotransplantation is being assessed.

  4. The Quality of Life in Chronic Pancreatitis: The Endoscopist's Point of View

    2006-01-01

    Full Text Available Due to its therapeutic properties, endoscopy can influence the quality of life (QoL of patients suffering from chronic pancreatitis (CP. Pancreatic ductal decompression represents the most frequent endoscopic procedure in patients with painful CP and it can be considered as a first-line treatment for improving the clinical condition. Endoscopy can limit surgery to unsuccessful or relapse cases. The best candidates for endoscopic treatment are patients with cephalic obstruction of the main pancreatic duct (MPD by stone(s and/or stricture(s with upstream dilation (type IV or, respectively, type V according to the Brussels or the Cambridge ERCP classification [1, 2]. These patients had pain as a consequence of an elevated intraductal pressure. Combined techniques are usually employed to remove stones and/or to dilate a stenosis, such as a pancreatic sphincterotomy, mechanic lithotripsy, extracorporeal shockwave lithotripsy (ESWL and pancreatic stent(s. Endoscopy has the potential of improving the QoL in patients with CP since it can decrease or entirely eliminate pancreatic pain and MPD dilation, two variables capable of impairing physical and mental domains [3, 4, 5]. In the Pezzilli et al. study [3], pain was the unique clinical variable able to significantly impair all physical and mental domains in a SF-36 questionnaire administered to 190 consecutive patients with proven CP.

    Two non-Hermitian PT-symmetric Hamiltonian systems are reconsidered by means of the algebraic method which was originally proposed for the pseudo-Hermitian Hamiltonian systems rather than for the PT-symmetric ones.Compared with the way converting a non-Hermitian Hamiltonian to its Hermitian counterpart,this method has the merit that keeps the Hilbert space of the non-Hermitian PT-symmetric Hamiltonian unchanged.In order to give the positive definite inner product for the PT-symmetric systems,a new operator V,instead of C,can be introduced.The operator V has the similar function to the operator C adopted normally in the PT-symmetric quantum mechanics,however,it can be constructed,as an advantage,directly in terms of Hamiltonians.The spectra of the two non-Hermitian PT-symmetric systems are obtained,which coincide with that given in literature,and in particular,the Hilbert spaces associated with positive definite inner products are worked out.

    Slime mould is a fascinating creature. It is the largest acellular organism known on this planet and a primordial being that had no need to undergo evolution. In nature, this proves it to be a very successful creature. As a biological curiosity, the species P. polycephalum serves as a model for network optimisation and cell motility in scientific experiments. It can be interpreted as an "agent" which distributively solves geometrical problems. The starting points for the experiments displayed here are sophisticated setups or growing environments that allow the organism to propagate and grow, yet under conditions that the artist has predefined, sometimes with interaction between human organisms...

    According to the characteristics of a complex cover panel, its geometry shape is described by the NURBS surface with great description capability. With the reference to the surface classification determined by Gauss curvature, the proportion of the mid-surface area between before and after being developed is derived from the displacement variation of the mid-surface in the normal vector direction of the sheet metal during the sheet metal forming process. Hereby, based on the curve development theory in differential geometry, a novel diagonal point by point surface development method is put forward to estimate a complex cover panel's blank contour efficiently. By comparing the sample's development result of diagonal point by point surface development method with that of available one-step method, the validity of the proposed surface development method is verified.

    We study interaction modalities for mobile devices (smartphones and tablets) that rely on a camera-based head tracking. This technique defines new possibilities for input and output interaction. For output, by computing the position of the device according to the user's head, it is for example possible to realistically control the viewpoint on a 3D scene (Head-Coupled Perspective, HCP). This technique improves the output interaction bandwidth by enhancing the depth perception and by allowing ...

    We report 3 studies of the referential pointing of 2 orangutans (Pongo pygmaeus). Chantek was raised in an enculturated environment; Puti, raised in a nursery, had a more typical captive life. In Experiment 1, flexibility of pointing behavior was investigated by requiring subjects to point in novel circumstances (for an out-of-sight tool, not food). In Experiment 2, we investigated the orangutans' comprehension of the significance of a human point in helping them to locate food. In Experiment 3, we investigated whether these pointing subjects comprehended that a human recipient must be looking for the point to achieve its attention-directing goal. In all experiments the enculturated orangutan showed better understanding of pointing than the captive orangutan. This finding is consistent with recent studies that have found differences in the cognitive and social-cognitive abilities of apes that have had different types of experience with humans.

    After a survey of the recent pedopsychiatric literature concerning the difficulties exhibited by young adoptees, we describe our own experience with 35 adopted children. The subjects were divided in two groups: a) the first group of 26 cases (74%) concerning clinical disturbances with no evident relation to the situation derived by the adoption; b) the second group of 9 cases (26%) concerning: 1. four cases ou rebellious behaviour against the adopters et 2. fives cases of camouflaged rejection of the adoptees by their adopters. These 9 cases are given with details; the characteristics of the other 26 cases are summarized. Our pedopsychiatric experience has shown that adoption was a failure in 26% of the cases related in the present study.

    Two different diagnostic systems are presented for a three-phase cycloconverter, feeding a reactive load. The cyclodrive is monitored by harmonic analysis of input and output waveforms via Fast Fourier Transform algorithm; the diagnostic systems are based on either If...Then... rules or neural network analysis of input and output spectra. Diagnostic system performances have been evaluated under several different cyclodrive operating conditions. Diagnostic systems comparison is made by means of cyclodrive availability evaluation, which is a measure of the quality of service that a system provides. 10 refs, 7 figs, 1 tab

  15. The addiction concept and technology: diagnosis, metaphor, or something else? a psychodynamic point of view.

    Many today suffer from an imbalance between life and life on the screen. When extreme, such as excessive gaming, clinicians retreat to familiar explanations, such as "Internet addiction." But the addiction concept is of limited value, limiting both research and treatment options. This article discusses an alternative. Pathological overuse is seen as a failed solution in which people become entrapped by technology's promise of delivering that which only life can offer, such as the grand adventure simulated in World of Warcraft. A two-part treatment approach of such "simulation entrapment" is described in which both the original problem and the entrapment are treated, the former by traditional psychodynamic psychotherapy and the later by highlighting differences between the technologically mediated experience and traditional experiences of being bodies together. The case of a college student suffering from pathological shame with excessive gaming as the failed solution is offered as an illustration. PMID:22976153

    Low activation ferritic/martensitic steels are good candidates for the future fusion reactors, for, relative to austenitic steels, their lower damage accumulation and moderate swelling under irradiation by the 14 MeV neutrons produced by the fusion reaction. Irradiation of these steels, e.g. EUROFER97, is known to produce hardening, loss of ductility, shift in ductile to brittle transition temperature and a reduction of fracture toughness and creep resistance starting at the lowest doses. Helium, produced by transmutation by the 14 MeV neutrons, is known to impact mechanical properties, but its effect at the microstructure level is still unclear. The mechanisms underlying the degradation of mechanical properties are not well understood, despite numerous studies on the evolution of the microstructure under irradiation. This impedes our ability to predict materials' behaviour at higher doses for use in the future fusion reactors. Simulations of these effects are now essential. An overview is presented on molecular dynamics simulations of the primary state of damage in iron and of the mobility of a dislocation, vector of plasticity, in the presence of a defect.

    Alcoholic liver disease (ALD) and the hepatitis C virus (HCV) are two common diseases in the western world. 30-40% of patients with ALD suffer from HCV and 70% of HCV patients are heavy drinkers. The association between the two diseases accelerates the chain of events that leads to liver cirrhosis and hepatocellular carcinoma (HCC). The reason for this is that the two diseases have a synergistic effect on oxidative stress, the immune component, and the mechanisms of carcinogenesis. The relative risk of liver cirrhosis and HCC has increased very significantly. A clinical condition of particular seriousness is represented by acute-on-chronic liver failure (ACLF) characterized by the recurrent superposition of an episode of severe acute alcoholic hepatitis (AAH) on a framework of advanced HCV-related chronic liver disease. Currently the possible failure to respond to medical therapy involves liver transplantation in selected patients. Antiviral therapy with PEG-IFN and Ribavirin enables similar results in a group of patients without ALD. The need to eradicate the infection represents a significant motivational reason for the abstention. Ultrasonographic surveillance should take place every six months and should be continued following possible viral eradication. Other associated diseases, but also the potential oncology of ethanol even after a long period of abstention may be the cause of HCC. This attitude will be followed by the introduction of new antiviral drugs. PMID:27012266

    We live in the Information Age, and information has become a critically important component of our life. The success of the Internet made huge amounts of it easily available and accessible to everyone. To keep the flow of this information manageable, means for its faultless circulation and effective handling have become urgently required. Considerable research efforts are dedicated today to address this necessity, but they are seriously hampered by the lack of a common agreement about "What is information?" In particular, what is "visual information" - human's primary input from the surrounding world. The problem is further aggravated by a long-lasting stance borrowed from the biological vision research that assumes human-like information processing as an enigmatic mix of perceptual and cognitive vision faculties. I am trying to find a remedy for this bizarre situation. Relying on a new definition of "information", which can be derived from Kolmogorov's compexity theory and Chaitin's notion of algorithmic inf...
