  2. Basic concepts in oceanography

    Small, L.F.

    1997-01-01

    Basic concepts in oceanography include major wind patterns that drive ocean currents, and the effects that the earth's rotation, positions of land masses, and temperature and salinity have on oceanic circulation and hence global distribution of radioactivity. Special attention is given to coastal and near-coastal processes such as upwelling, tidal effects, and small-scale processes, as radionuclide distributions are currently most associated with coastal regions.

  3. Precompound Reactions: Basic Concepts

    Weidenmueller, H. A.

    2008-01-01

    Because of the non-zero nuclear equilibration time, the compound-nucleus scattering model fails when the incident energy exceeds 10 or 20 MeV, and precompound reactions become important. Basic ideas used in the quantum-statistical approaches to these reactions are described

  4. Basic concepts of epidemiology

    Savitz, D.A.

    1984-01-01

    Epidemiology can be defined simply as the science of the distribution and determinants of disease in human populations. As a descriptive tool, epidemiology can aid health care service providers, for example, in allocation of resources. In its analytic capacity, the epidemiologic approach can help identify determinants of disease through the study of human populations. Epidemiology is primarily an observational rather than experimental methodology, with corresponding strengths and limitations. Relative to other approaches for assessing disease etiology and impacts of potential health hazards, epidemiology has a rather unique role that is complementary to, but independent of, both basic biologic sciences and clinical medicine. Experimental biologic sciences such as toxicology and physiology provide critical information on biologic mechanisms of disease required for causal inference. Clinical medicine often serves as the warning system that provides etiologic clues to be pursued through systematic investigation. The advantage of the epidemiologic approach is its reliance on human field experience, that is, the real world. While laboratory experimentation is uniquely well suited to defining potential hazards, it can neither determine whether human populations have actually been affected nor quantify that effect. Building all the complexities of human behavior and external factors into a laboratory study or mathematical model is impossible. By studying the world as it exists, epidemiology examines the integrated, summarized product of the myriad factors influencing health

  10. Basic Concepts of Reading Instruction

    Gökhan ARI

    2017-12-01

    Full Text Available Reading act is performed by connected physiological, psychological and cognitive processes. The operations taking place in these processes are expected to continue for life by being developed with certain strategies. A lot of information is gained with reading skill in education life. Therefore, basic concepts that constitute reading education in teaching and improving reading are important for teachers. The aim of this study is to submit information compiled from the literature about reading education process and which basic concepts are used in reading education. While teaching reading from part to whole, from whole to part and interactional approaches are used. From part to whole approach is at the forefront. Then with interactional approach strategies, both code solving and making sense is improved. Teachers should know the characteristics of bouncing, stopping, turning back, and scanning movements of the eye both in code solving and making sense. The teacher should configure the teaching for the students to gain fluid reading elements by making use of reading out and reading silently. After reading act is acquired; good reader characteristics should be gained by improving asking questions, guessing, summarizing, interpretation skills in integrated readings. Reading skill is improved by studies on the text. Therefore, the students should come across texts that are suitable to their levels, textuality and readability criteria. The vocabulary of children should be improved in a planned way with text-based word and meaning studies. Fluid reading, making sense and interpretation skills of children should be pursued with different evaluation types. In the long term, work should be done to make reading a habit for them.

  18. Stereotactic radiosurgery: basic concepts and current status

    Gaur, Maheep Singh

    2016-01-01

    Term Stereotactic Radiosurgery was coined by Prof Lars Leksell in 1951 as concept. Leksell's experimented together with the radiobiologist Borje Larsson in Uppsala, on trying to develop 'stereotactic radiosurgery', aimed at lesioning in the central brain in functional operations such as thalamotomy and capsulotomy. Clinical experiments using a proton beam were initiated at the Gustav Werner Institute in Uppsala, and a few patients had been treated. Experiences from these led Leksell to design a multi-source 'beam knife', which became ready for use in 1967 as the first 'Gamma Knife' and installed at the private hospital Sophiahammet in Stockholm as a clinical research unit. Moving from functional neurosurgery today Gamma knife is used for a wide range on brain tumors, vascular malformations and functional disorders. Introduction of newer technology in navigation and radiation delivery has made it possible to do whole body Radiosurgery. Various technologies, basic principles, radiobiological aspects and applications will be discussed. (author)

  2. Basic principles simulators - concept training simulators

    Benkert, J.

    1986-01-01

    Basic Principles Simulators have the purpose of teaching general concepts, demonstrating and displaying the fundamental physical processes of a plant. They are used to illustrate theory to students and also to provide a preliminary training to the operators, to aquaint them with the basic dynamic interactions of the various systems during the normal operation of a plant, and to show the consequences of the most important and common transients and malfunctions. Basic principles simulators may vary in size from small desk cabinets to large panels. They represent with a certain detail the nuclear and thermohydraulic part of the plant. The availability of video displays allows to present detailed information about process parameters which are not shown on the control panels. In general the overall plant behaviour is represented well. Limitations are mostly found in the areas of logic and control. (orig./HP)

  3. Spent nuclear fuel storage - Basic concept

    Krempel, Ascanio; Santos, Cicero D. Pacifici dos; Sato, Heitor Hitoshi; Magalhaes, Leonardo de

    2009-01-01

    According to the procedures adopted in others countries in the world, the spent nuclear fuel elements burned to produce electrical energy in the Brazilian Nuclear Power Plant of Angra do Reis, Central Nuclear Almirante Alvaro Alberto - CNAAA will be stored for a long time. Such procedure will allow the next generation to decide how they will handle those materials. In the future, the reprocessing of the nuclear fuel assemblies could be a good solution in order to have additional energy resource and also to decrease the volume of discarded materials. This decision will be done in the future according to the new studies and investigations that are being studied around the world. The present proposal to handle the nuclear spent fuel is to storage it for a long period of time, under institutional control. Therefore, the aim of this paper is to introduce a proposal of a basic concept of spent fuel storage, which involves the construction of a new storage building at site, in order to increase the present storage capacity of spent fuel assemblies in CNAAA installation; the concept of the spent fuel transportation casks that will transfer the spent fuel assemblies from the power plants to the Spent Fuel Complementary Storage Building and later on from this building to the Long Term Intermediate Storage of Spent Fuel; the concept of the spent fuel canister and finally the basic concept of the spent fuel long term storage.

  5. Basic concepts from magnetic resonance imaging

    Rodriguez Arroyo, Diego

    2011-01-01

    The use of magnetic resonance imaging (MRI) has grown exponentially, due in part to excellent anatomic and pathologic detail provided by the modality, as recent technological advances that have led to more rapid acquisition times. Radiology residents in different parts of the world now receive training in MR images from their first year of residence, included the pulse sequences training spin-echo, gradient-echo, inversion-recovery, echo-planar image and MR angiographic sequences, commonly used in medical imaging. However, to optimize the use of this type of study, it has been necessary to understand the basic concepts of physics, included the concepts of recovery T1, degradation T2* and T2, repetition time, echo time, and the effects of chemical shift. Additionally, it has been important to understand the contrast weighting for better representation of specific tissues and thus perform an appropriate differential diagnosis of various pathological processes.

  6. Discussion of thermal extraction chamber concepts for Lunar ISRU

    Pfeiffer, Matthias; Hager, Philipp; Parzinger, Stephan; Dirlich, Thomas; Spinnler, Markus; Sattelmayer, Thomas; Walter, Ulrich

    The Exploration group of the Institute of Astronautics (LRT) of the Technische Universitüt a München focuses on long-term scenarios and sustainable human presence in space. One of the enabling technologies in this long-term perspective is in-situ resource utilization (ISRU). When dealing with the prospect of future manned missions to Moon and Mars the use of ISRU seems useful and intended. The activities presented in this paper focus on Lunar ISRU. This basically incorporates both the exploitation of Lunar oxygen from natural rock and the extraction of solar wind implanted particles (SWIP) from regolith dust. Presently the group at the LRT is examining possibilities for the extraction of SWIPs, which may provide several gaseous components (such as H2 and N2) valuable to a human presence on the Moon. As a major stepping stone in the near future a Lunar demonstrator/ verification experiment payload is being designed. This experiment, LUISE (LUnar ISru Experiment), will comprise a thermal process chamber for heating regolith dust (grain size below 500m), a solar thermal power supply, a sample distribution unit and a trace gas analysis. The first project stage includes the detailed design and analysis of the extraction chamber concepts and the thermal process involved in the removal of SWIP from Lunar Regolith dust. The technique of extracting Solar Wind volatiles from Regolith has been outlined by several sources. Heating the material to a threshold value seems to be the most reasonable approach. The present paper will give an overview over concepts for thermal extraction chambers to be used in the LUISE project and evaluate in detail the pros and cons of each concept. The special boundary conditions set by solar thermal heating of the chambers as well as the material properties of Regolith in a Lunar environment will be discussed. Both greatly influence the design of the extraction chamber. The performance of the chamber concepts is discussed with respect to the

  7. Basic concepts in marine biology and ecology

    Small, L.F.

    1997-01-01

    An introduction to the marine biota, and how the biota interact with their physico-chemical environment, is given in this chapter. In particular, food web and trophic level relationships are discussed, from phytopIankton production through consumer organisms and the ''microbial loop''. The effects of organism size and functional relationships within the food web paradigm are emphasized, rather than taxonomic relationships. Examples initially given in terms of carbon, nitrogen, or energy transfer through food webs are placed in context with radionuclide transfer and the concept of biomagnification. (author)

  11. Basic concepts and assumptions behind the new ICRP recommendations

    Lindell, B.

    1979-01-01

    A review is given of some of the basic concepts and assumptions behind the current recommendations by the International Commission on Radiological Protection in ICRP Publications 26 and 28, which form the basis for the revision of the Basic Safety Standards jointly undertaken by IAEA, ILO, NEA and WHO. Special attention is given to the assumption of a linear, non-threshold dose-response relationship for stochastic radiation effects such as cancer and hereditary harm. The three basic principles of protection are discussed: justification of practice, optimization of protection and individual risk limitation. In the new ICRP recommendations particular emphasis is given to the principle of keeping all radiation doses as low as is reasonably achievable. A consequence of this is that the ICRP dose limits are now given as boundary conditions for the justification and optimization procedures rather than as values that should be used for purposes of planning and design. The fractional increase in total risk at various ages after continuous exposure near the dose limits is given as an illustration. The need for taking other sources, present and future, into account when applying the dose limits leads to the use of the commitment concept. This is briefly discussed as well as the new quantity, the effective dose equivalent, introduced by ICRP. (author)

  12. A brain-based account of "basic-level" concepts.

    Bauer, Andrew James; Just, Marcel Adam

    2017-11-01

    This study provides a brain-based account of how object concepts at an intermediate (basic) level of specificity are represented, offering an enriched view of what it means for a concept to be a basic-level concept, a research topic pioneered by Rosch and others (Rosch et al., 1976). Applying machine learning techniques to fMRI data, it was possible to determine the semantic content encoded in the neural representations of object concepts at basic and subordinate levels of abstraction. The representation of basic-level concepts (e.g. bird) was spatially broad, encompassing sensorimotor brain areas that encode concrete object properties, and also language and heteromodal integrative areas that encode abstract semantic content. The representation of subordinate-level concepts (robin) was less widely distributed, concentrated in perceptual areas that underlie concrete content. Furthermore, basic-level concepts were representative of their subordinates in that they were neurally similar to their typical but not atypical subordinates (bird was neurally similar to robin but not woodpecker). The findings provide a brain-based account of the advantages that basic-level concepts enjoy in everyday life over subordinate-level concepts: the basic level is a broad topographical representation that encompasses both concrete and abstract semantic content, reflecting the multifaceted yet intuitive meaning of basic-level concepts.

  14. Modern concepts for basic radiobiological factors characterizing tumor tissue radiosensitivity

    Gocheva, L.; Sergieva, K.

    2002-01-01

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

  18. Endoradiotherapy in cancer treatment--basic concepts and future trends.

    Zoller, Frederic; Eisenhut, Michael; Haberkorn, Uwe; Mier, Walter

    2009-12-25

    Endoradiotherapy represents an alternative therapeutic method in cancer treatment with advantageous features compared to chemotherapy and radiation therapy. Intelligent dose delivery concepts using small drugs, peptides or antibodies as radionuclide carriers enable the verification of a selective accumulation in the tumour lesion and to reduce radiation toxicity for the peripheral organs. The development of endoradiotherapeutic agents, especially chelator-conjugated biomolecules, for example ibritumomab tiuxetan or DOTATOC, gains importance due to the stable complexation of versatile radiometals, such as (90)Y or (177)Lu. The rational design of novel target binding sides and their grafting into a drug scaffold is a highly promising strategy, which may promote further implication in endoradiotherapy. This review highlights the basic concepts of endoradiotherapy and discusses the potential of targeted therapy and the properties of energy-rich particles emitted by radionuclides for tumour therapy.

  2. Nanomedicine concepts in the general medical curriculum: initiating a discussion

    Sweeney AE

    2015-12-01

    Full Text Available Aldrin E Sweeney Center for Teaching & Learning, Ross University School of Medicine, Roseau, Commonwealth of Dominica Abstract: Various applications of nanoscale science to the field of medicine have resulted in the ongoing development of the subfield of nanomedicine. Within the past several years, there has been a concurrent proliferation of academic journals, textbooks, and other professional literature addressing fundamental basic science research and seminal clinical developments in nanomedicine. Additionally, there is now broad consensus among medical researchers and practitioners that along with personalized medicine and regenerative medicine, nanomedicine is likely to revolutionize our definitions of what constitutes human disease and its treatment. In light of these developments, incorporation of key nanomedicine concepts into the general medical curriculum ought to be considered. Here, I offer for consideration five key nanomedicine concepts, along with suggestions regarding the manner in which they might be incorporated effectively into the general medical curriculum. Related curricular issues and implications for medical education also are presented.

  3. Basic Concepts for rethinking environmental issues

    Gonzalez Ladron de Guevara, Francisco Jose; Valencia Cuellar, Jorge

    2013-01-01

    This article presents a review of the fundamental concepts from which environmental problems have been explained and solved during the last decades. Environment is understood as an encounter between nature and culture that is a social construct that reflects the interaction between human beings and the biophysical space in which they live. On the other hand, development is conceived as the ability that societies have to develop their potentialities, being a notion of a totalizing and ethical political nature, which incorporates the biophysical and social heritage of a certain society. Regarding the concept of culture, it must be said that it is built upon the basis that this is an adaptive strategy of the human species. Finally, the relationships between the concepts of culture, environment and development are studied in order to formulate a new perspective for rethinking the environmental issue, so that, in turn, it could be used to redirect survival strategies that human beings currently apply in their interaction with the environment.

A review of papers on effect sizes and commonly repeated statistical analyses suggests that it is important to discuss effect sizes relative to bivariate correlation, t-tests, analysis of variance/covariance,…

  6. REVIVING SOME BASIC CONCEPTS IN ETHICAL REGISTER

    CARMEN COZMA

    2015-11-01

    Full Text Available Being sensitive to the challenges placed before us in a globalizing world, it is obviously that the ethical benchmark became one of the priorities in our individual and communitarian life. An in-depth knowledge of both the axiological and normative dimensions of ethics can open an important way for an adequate approach of today’s problems. By rethinking the foundations, we may reach accuracy as regards what does really matter in life. So, a call to revive some value-laden concepts coming from the ancient Greek moral philosophy represents the aim of this paper, to emphasize the support given us by healthy roots for reflection and understanding, in part at least, our present problematic situation in the world.

  7. Basic general concepts in the network analysis

    Boja Nicolae

    2004-01-01

    Full Text Available This survey is concerned oneself with the study of those types of material networks which can be met both in civil engineering and also in electrotechnics, in mechanics, or in hydrotechnics, and of which behavior lead to linear problems, solvable by means of Finite Element Method and adequate algorithms. Here, it is presented a unitary theory of networks met in the domains mentioned above and this one is illustrated with examples for the structural networks in civil engineering, electric circuits, and water supply networks, but also planar or spatial mechanisms can be comprised in this theory. The attention is focused to make evident the essential proper- ties and concepts in the network analysis, which differentiate the networks under force from other types of material networks. To such a network a planar, connected, and directed or undirected graph is associated, and with some vector fields on the vertex set this graph is endowed. .

  9. Proposals of new basic concepts on safety and radioactive waste and of new High Temperature Gas-cooled Reactor based on these basic concepts

    Ogawa, Masuro

    2016-01-01

    Highlights: • The author proposed new basic concepts on safety and radioactive waste. • A principle of ‘continue confining’ to realize the basic concept on safety is also proposed. • It is indicated that only a HTGR can attain the conditions required from the principle. • Technologies to realize the basic concept on radioactive waste are also discussed. • A New HTGR system based on the new basic concepts is proposed. - Abstract: A new basic concept on safety of ‘Not causing any serious catastrophe by any means’ and a new basic concept on radioactive waste of ‘Not returning any waste that possibly affects the environment’ are proposed in the present study, aiming at nuclear power plants which everybody can accept, in consideration of the serious catastrophe that happened at Fukushima Japan in 2011. These new basic concepts can be found to be valid in comparison with basic concepts on safety and waste in other industries. The principle to realize the new basic concept on safety is, as known well as the inherent safety, to use physical phenomena such as Doppler Effect and so on which never fail to work even if all equipment and facilities for safety lose their functions. In the present study, physical phenomena are used to ‘continue confining’, rather than ‘confine’, because the consequence of emission of radioactive substances to the environment cannot be mitigated. To ‘continue confining’ is meant to apply natural correction to fulfill inherent safety function. Fission products must be detoxified to realize the new basic concept on radioactive waste, aiming at the final processing and disposal of radioactive wastes as same as that in the other wastes such as PCB, together with much efforts not to produce radioactive wastes and to reduce their volume nevertheless if they are emitted. Technology development on the detoxification is one of the most important subjects. A new High Temperature Gas-cooled Reactor, namely the New HTGR

  11. Medical cyclotron basic concepts and its applications

    Kumar, Rajeev; Sonkawade, R.G.

    2012-01-01

    More than 3000 nuclides are known, of which approximately 2700 are radioactive, and rest are stable. The majority of radionuclides are artificially produced in the reactor and cyclotron. In a cyclotron, Charge particle such as proton, Deuteron, á (Alpha) particle, 3 He particles and so forth are accelerated in circular paths within the Dees under vacuum by means of an electromagnetic field. These accelerated particles can possess few KeV to several BeV of kinetic energy depending on the design of the cyclotron. At our setup we have an 11 MeV dual beam multi target cyclotron which is capable producing 11 C, 13 N, 15 O, 18 F and 2 F radioisotopes and all have been successfully produced and tested in our lab. Earlier cyclotrons were the best source of high-energy beams for nuclear physics experiments; several cyclotrons are still in use for this type of research. Cyclotrons can be used to treat cancer. Ion beams from cyclotrons can be used, as in proton therapy. The positron emitting isotopes are suitable for PET imaging. As discussed we are producing mainly Carbon-11, Nitrogen-13, Oxygen-15, and Fluorine-18: These are positron emitters used in PET for studying brain physiology and pathology, in particular for localizing epileptic focus, and in dementia, psychiatry and neuropharmacology studies. So these are having significant role in diagnosis of Oncological, Neurological and Cardiological disorder. More than ninety percent we are producing 18 F in FDG. 18 F in FDG (Flouro-Deoxy-glucose) has become very important in detection of cancers and the monitoring of progress in their treatment, using PET. Medical cyclotron is complex equipment requiring delicate handling by highly trained personnel. The aim of this article is to highlight few finer aspects of Medical cyclotron operation, including precautions for safety and smooth functioning of this sophisticated equipment. (author)

  14. Health recommender systems: concepts, requirements, technical basics and challenges.

    Wiesner, Martin; Pfeifer, Daniel

    2014-03-03

    During the last decades huge amounts of data have been collected in clinical databases representing patients' health states (e.g., as laboratory results, treatment plans, medical reports). Hence, digital information available for patient-oriented decision making has increased drastically but is often scattered across different sites. As as solution, personal health record systems (PHRS) are meant to centralize an individual's health data and to allow access for the owner as well as for authorized health professionals. Yet, expert-oriented language, complex interrelations of medical facts and information overload in general pose major obstacles for patients to understand their own record and to draw adequate conclusions. In this context, recommender systems may supply patients with additional laymen-friendly information helping to better comprehend their health status as represented by their record. However, such systems must be adapted to cope with the specific requirements in the health domain in order to deliver highly relevant information for patients. They are referred to as health recommender systems (HRS). In this article we give an introduction to health recommender systems and explain why they are a useful enhancement to PHR solutions. Basic concepts and scenarios are discussed and a first implementation is presented. In addition, we outline an evaluation approach for such a system, which is supported by medical experts. The construction of a test collection for case-related recommendations is described. Finally, challenges and open issues are discussed.

    2001-05-01

    To determine, for the teaching of basic health concepts to school-age children, the effectiveness of an educational strategy based on traditional children's games. Intervention study carried out in the city of Durango, Mexico, in June 2000 with 300 children from 9 to 11 years old. The children were randomly divided into two groups. The children in Group A used a modified version of a Mexican popular game called Serpientes y Escaleras (Snakes and Ladders) that included messages on basic health concepts; the children in Group B made up the control group and did not play the modified game. At baseline there were no significant differences between the two groups in terms of age, grade level, or their scores on a knowledge test of basic health concepts. After the educational intervention, the health concepts test scores, out of a maximum possible of 10, were 9.3 +/- 0.8 for Group A and 7.5 +/- 1.1 for Group B (P games that include health and hygiene messages can be an alternative for teaching basic health concepts.

  5. Digital ethnicity: discussion of a concept and implications for education

    Nan B. Adams

    2011-09-01

    Full Text Available Interaction with the rapidly expanding digital technologies for education, work, and play has drastically changed the processes and practices of world populations. As societies evolve in response to these new communication and calculation tools, the need arises to understand the sometimes unique but increasingly common change in cultures. The Digital Ethnicity Scale (DES, utilizing Longstreet’s (1978, Aspects of Ethnicity (New York: Teachers College Press model of the Aspects of Ethnicity, was developed to describe the emergence of new cultural patterns of behavior that result from the influence of human interaction with digital communication technologies (Adams, DeVaney, and Longstreet (2010 Comput. Hum. Behav. 26(6: 1822–1830. Longstreet’s definition of ethnicity focuses on cultural development during the earliest stages of human development, prior to the onset of children’s abstract thinking. The ultimate goal for the development of the DES is to describe those aspects of digital ethnicity and collect these descriptions along with demographic data to achieve profiles of various digital ethnicities. A discussion of the guiding concept and overview of the development of the DES seeks to present a description of these digital ethnic profiles that may provide insight into the educational needs of rapidly changing societal groupings with hopes of providing guidance for educational practice.

    Mills, W.A.; Mossman, K.L.

    1991-01-01

    The present criterion for radiation protection appears to be exposure reduction rather than adequate protection of health. The 1990 ICRP draft recommendations for a system of dose limitation would further implement this more restrictive criterion by implementing certain academic concepts and assumptions. These concepts and assumptions are discussed and the suggestion is made that the radiation protection community needs to carefully examine the need for the complex system proposed

Other terms were added by Skinner (1938/1991) to describe his…

  9. Development of FBR integrity system code. Basic concept

    Asayama, Tai

    2001-05-01

    For fast breeder reactors to be commercialized, they must be more reliable, safer, and at the same, economically competitive with future light water reactors. Innovation of elevated temperature structural design standard is necessary to achieve this goal. The most powerful way is to enlarge the scope of structural integrity code to cover items other than design evaluation that has been addressed in existing codes. Items that must be newly covered are prerequisites of design, fabrication, examination, operation and maintenance, etc. This allows designers to choose the most economical combination of design variations to achieve specific reliability that is needed for a particular component. Designing components by this concept, a cost-minimum design of a whole plant can be realized. By determining the reliability that must be achieved for a component by risk technologies, further economical improvement can be expected by avoiding excessive quality. Recognizing the necessity for the codes based on the new concept, the development of 'FBR integrity system code' began in 2000. Research and development will last 10 years. For this development, the basic logistics and system as well as technologies that materialize the concept are necessary. Original logistics and system must be developed, because no existing researches are available in and out of Japan. This reports presents the results of the work done in the first year regarding the basic idea, methodology, and structure of the code. (author)

  13. Concept Systems and Ontologies: Recommendations for Basic Terminology

    Klein, Gunnar O.; Smith, Barry

    This essay concerns the problems surrounding the use of the term ``concept'' in current ontology and terminology research. It is based on the constructive dialogue between realist ontology on the one hand and the world of formal standardization of health informatics on the other, but its conclusions are not restricted to the domain of medicine. The term ``concept'' is one of the most misused even in literature and technical standards which attempt to bring clarity. In this paper we propose to use the term ``concept'' in the context of producing defined professional terminologies with one specific and consistent meaning which we propose for adoption as the agreed meaning of the term in future terminological research, and specifically in the development of formal terminologies to be used in computer systems. We also discuss and propose new definitions of a set of cognate terms. We describe the relations governing the realm of concepts, and compare these to the richer and more complex set of relations obtaining between entities in the real world. On this basis we also summarize an associated terminology for ontologies as representations of the real world and a partial mapping between the world of concepts and the world of reality.

  14. Discussion on concepts for radiological dosimetric quantities in the Japan Health Physics Society

    Takahashi, Fumiaki; Oda, Keiji

    2007-01-01

    Many dosimetric quantities have been used for radiation protection purpose. The International Commission on Radiological Protection (ICRP) has recommended protection quantities and the International Commission on Radiation Units and Measurements (ICRU) has introduced operational quantities to provide a reasonable estimate of the protection quantities. Enthusiastic discussions are continuously made on the issues of the dosimetric quantities, such as basic biological data for the definition of these quantities and applicability of the quantities to actual radiation protection practice. At the moment, some changes are being proposed concerning dosimetric quantities in the draft recommendations of ICRP, opened for consultation in recent years. Thus, the Japan Health Physics Society (JHPS) established the Expert Committee on concepts of Dosimetric Quantities used in radiological protection (ECDQ) in April 2005 to reviewed and discuss issues in the dosimetric quantities.

  15. Atomic and molecular spectroscopy basic concepts and applications

    Kakkar, Rita

    2015-01-01

    Spectroscopy is the study of electromagnetic radiation and its interaction with solid, liquid, gas and plasma. It is one of the widely used analytical techniques to study the structure of atoms and molecules. The technique is also employed to obtain information about atoms and molecules as a result of their distinctive spectra. The fast-spreading field of spectroscopic applications has made a noteworthy influence on many disciplines, including energy research, chemical processing, environmental protection and medicine. This book aims to introduce students to the topic of spectroscopy. The author has avoided the mathematical aspects of the subject as far as possible; they appear in the text only when inevitable. Including topics such as time-dependent perturbation theory, laser action and applications of Group Theory in interpretation of spectra, the book offers a detailed coverage of the basic concepts and applications of spectroscopy.

  16. APPLICATION OF THE BASIC INCOME CONCEPT IN UKRAINIAN ECONOMY

    A. Stavytskyy

    2016-01-01

    Full Text Available Finance for the social sphere remains a great challenge in modern economy. The necessity of adequate living standards under limited resources raises a complicated problem for governments to provide appropriate distributing mechanism among the most vulnerable sections of the population. The paper analysed the concept of absolute basic income, which in some EU countries is considered as a substitution for a modern system of social security. Inequality of incomes creates not only a social problem but it is also an obstacle in the way of economic growth. It leads to the conclusion that government should provide some strategy to avoid high inequality. The model of rational individual with certain basic income is under investigation. The analysis of the model suggests that the presence of additional income not only facilitates more effective involvement of individuals to work, but it is a sort of indisputable factor for guaranteeing freedom of individuals and increasing their mutual respect. Thus, the idea of basic income, which spreads among European countries, has not only economic, but also political and psychological components that may affect the mentality of people in future. It is demonstrated that the transition to a new social security schemes in Ukraine can accumulate from 856 to 1020 bln. UAH in 2015 prices. It can provide guaranteed monthly payments from 1928 to 2297 UAH per capita and from 482 to 574 USD per child without changing the structure of the budget in case of replacement minimum pensions, minimum wages and full monetization of privileges. Obviously, such strategy not only would improve the efficiency of budget spending, but also produce a multiplier effect on the economy by changing and optimizing the consumption patterns of the population, increasing the competition in all markets for a real consumer. It has a chance of reducing the struggle to obtain state funds through tenders. However, the transition to the new system can be

  17. From basic concepts to emerging technologies in regional anesthesia.

    Dillane, Derek; Tsui, Ban C H

    2010-10-01

    The present article details how our understanding of the basic concepts of regional anesthesia has recently evolved. We will appraise current technological advances and question the commensurate nature of the relationship between tradition and innovation. Ultrasound localization has enhanced our understanding of the needle-nerve relationship. Intraneural injection of local anesthetic may occur with greater frequency than previously thought without inevitably leading to neurological complications. The ratio of neural to non-neural tissue varies both between and within nerves and may be an important determinant of neural injury. Ultrasonographic evidence of intraneural injection is subject to observer expertise and the resolution of the ultrasound image. Current ultrasound resolution capability does not reliably permit differentiation between intrafascicular and extrafascicular drug injection. Perineural electrical impedance may be a determinant of current threshold and conceivably distinguish between intraneural and extraneural tissue. Technology that enhances the sonographic image of both procedure needle and target nerve is the focus of current endeavors in ultrasound innovation.There is inconclusive evidence that the use of ultrasound technology has reduced the incidence of local anesthetic toxicity. Lipid emulsion therapy is now an accepted treatment for systemic local anesthetic toxicity. There are new reports on the development of an ultra long-acting local anesthetic agent that would permit lower doses and superannuate catheter-based continuous regional anesthesia techniques. Over the past decade, our understanding of the fundamental concepts of regional anesthesia continues to be challenged by emerging experimental and clinical evidence.

  18. Initiating Young Children into Basic Astronomical Concepts and Phenomena

    Kallery, M.

    2010-07-01

    In the present study we developed and implemented three units of activities aiming at acquainting very young children with basic astronomical concepts and phenomena such as the sphericity of the earth, the earth’s movements and the day/night cycle. The activities were developed by a group composed of a researcher/facilitator and six early-years teachers. In the activities children were presented with appropriate for their age scientific information along with conceptual tools such as a globe and an instructional video. Action research processes were used to optimize classroom practices and to gather useful information for the final shaping of the activities and the instruction materials. In these activities the adopted approach to learning can be characterized as socially constructed. The results indicated awareness of concepts and phenomena that the activities dealt with in high percentages of children, storage of the new knowledge in the long term memory and easy retrieval of it, and children’s enthusiasm for the subject.

  19. Single or multi-repository concept? A personal contribution to the discussion of pros and cons

    Closs, K.-D.; Duphorn, K.; Kuehn, K.

    2002-01-01

    The coalition agreement concluded between the parties in government, i.e. SPD and Alliance 90/The Greens, after the 1998 federal elections provided for an approach to back-end fuel cycle conditions for German nuclear power plants which differed from the practice intended up to that point. Among other things, only one single repository in deep geologic formations is to be available approximately from 2030 on. Exploration of the Gorleben salt dome is to be interrupted because of prevailing doubts while, at the same time, a basic discussion is to be held about potentially suitable host rock varieties and sites. The 'Working Party of Selection Procedures for Repository Sites (AkEnd)' instituted by the federal government is to elaborate scientific siting criteria under these conditions. The authors, who are members of AkEnd, come to the conclusion, based on technical findings and the historical back-end fuel cycle and siting situation in Germany, that a multi-repository concept incorporates substantial advantages. These are the aspects referred to: - Back-end fuel cycle concept: The multi-repository concept offers clearcut advantages in the far advanced Konrad repository project. This is true also against the background of the volume of waste with negligible heat generation to be managed by public authorities. - Long-term safety: Advantages exist, among other things, with respect to technical safety regarding possible compromises in a single-repository concept and the possible restriction of the number of potential sites. - Methods of detection: Spreading the waste over two or more repositories offers benefits in the technical aspects of detection. - Cost: A differentiated assessment of the cost arising in connection with the total amount of waste to be stored in repositories indicates benefits of a multi-repository concept, especially for the public authorities.

  1. Structural equation modeling with EQS basic concepts, applications, and programming

    Byrne, Barbara M

    2013-01-01

    Readers who want a less mathematical alternative to the EQS manual will find exactly what they're looking for in this practical text. Written specifically for those with little to no knowledge of structural equation modeling (SEM) or EQS, the author's goal is to provide a non-mathematical introduction to the basic concepts of SEM by applying these principles to EQS, Version 6.1. The book clearly demonstrates a wide variety of SEM/EQS applications that include confirmatory factor analytic and full latent variable models. Written in a "user-friendly" style, the author "walks" the reader through the varied steps involved in the process of testing SEM models: model specification and estimation, assessment of model fit, EQS output, and interpretation of findings. Each of the book's applications is accompanied by: a statement of the hypothesis being tested, a schematic representation of the model, explanations of the EQS input and output files, tips on how to use the pull-down menus, and the data file upon which ...

  6. Death talk: Basic linguistic rules and communication in perinatal and paediatric end-of-life discussions.

    Xafis, Vicki; Watkins, Andrew; Wilkinson, Dominic

    2016-04-01

    This paper considers clinician/parent communication difficulties noted by parents involved in end-of-life decision-making in the light of linguistic theory. Grice's Cooperative Principle and associated maxims, which enable effective communication, are examined in relation to communication deficiencies that parents have identified when making end-of-life decisions for the child. Examples from the literature are provided to clarify the impact of failing to observe the maxims on parents and on clinician/parent communication. Linguistic theory applied to the literature on parental concerns about clinician/parent communication shows that the violation of the maxims of quantity, quality, relation, and manner as well as the stance that some clinicians adopt during discussions with parents impact on clinician/parent communication and lead to distrust, anger, sadness, and long-term difficulties coping with the experience of losing one's child. Parents have identified communication deficiencies in end-of-life discussions. Relating these communication deficiencies to linguistic theory provides insight into communication difficulties but also solutions. Gaining an understanding of basic linguistic theory that underlies human interactions, gaining insight into the communication deficiencies that parents have identified, and modifying some communication behaviours in light of these with the suggestions made in this article may lead to improved clinician/parent communication.

  11. Use of modulated excitation signals in ultrasound. Part I: Basic concepts and expected benefits

    Misaridis, Thanassis; Jensen, Jørgen Arendt

    2005-01-01

    This paper, the first from a series of three papers on the application of coded excitation signals in medical ultrasound, discusses the basic principles and ultrasound-related problems of pulse compression. The concepts of signal modulation and matched filtering are given, and a simple model...... of attenuation relates the matched filter response with the ambiguity function, known from radar. Based on this analysis and the properties of the ambiguity function, the selection of coded waveforms suitable for ultrasound imaging is discussed. It is shown that linear frequency modulation (FM) signals have...... that in the case of linear FM signals, a SNR improvement of 12 to 18 dB can be expected for large imaging depths in attenuating media, without any depth-dependent filter compensation. In contrast, nonlinear FM modulation and binary codes are shown to give a SNR improvement of only 4 to 9 dB when processed...

  12. The availability and accessibility of basic concept vocabulary in AAC software: a preliminary study.

    McCarthy, Jillian H; Schwarz, Ilsa; Ashworth, Morgan

    2017-09-01

    Core vocabulary lists obtained through the analyses of children's utterances include a variety of basic concept words. Supporting young children who use augmentative and alternative communication (AAC) to develop their understanding and use of basic concepts is an area of practice that has important ramifications for successful communication in a classroom environment. This study examined the availability of basic concept words across eight frequently used, commercially available AAC language systems, iPad© applications, and symbol libraries used to create communication boards. The accessibility of basic concept words was subsequently examined using two AAC language page sets and two iPad applications. Results reveal that the availability of basic concept words represented within the different AAC language programs, iPad applications, and symbol libraries varied but was limited across programs. However, there is no significant difference in the accessibility of basic concept words across the language program page sets or iPad applications, generally because all of them require sophisticated motor and cognitive plans for access. These results suggest that educators who teach or program vocabulary in AAC systems need to be mindful of the importance of basic concept words in classroom settings and, when possible, enhance the availability and accessibility of these words to users of AAC.

  13. Pseudo-populations a basic concept in statistical surveys

    Quatember, Andreas

    2015-01-01

    This book emphasizes that artificial or pseudo-populations play an important role in statistical surveys from finite universes in two manners: firstly, the concept of pseudo-populations may substantially improve users’ understanding of various aspects in the sampling theory and survey methodology; an example of this scenario is the Horvitz-Thompson estimator. Secondly, statistical procedures exist in which pseudo-populations actually have to be generated. An example of such a scenario can be found in simulation studies in the field of survey sampling, where close-to-reality pseudo-populations are generated from known sample and population data to form the basis for the simulation process. The chapters focus on estimation methods, sampling techniques, nonresponse, questioning designs and statistical disclosure control.This book is a valuable reference in understanding the importance of the pseudo-population concept and applying it in teaching and research.

  16. The concept of ageing in evolutionary algorithms: Discussion and inspirations for human ageing.

    Dimopoulos, Christos; Papageorgis, Panagiotis; Boustras, George; Efstathiades, Christodoulos

    2017-04-01

    This paper discusses the concept of ageing as this applies to the operation of Evolutionary Algorithms, and examines its relationship to the concept of ageing as this is understood for human beings. Evolutionary Algorithms constitute a family of search algorithms which base their operation on an analogy from the evolution of species in nature. The paper initially provides the necessary knowledge on the operation of Evolutionary Algorithms, focusing on the use of ageing strategies during the implementation of the evolutionary process. Background knowledge on the concept of ageing, as this is defined scientifically for biological systems, is subsequently presented. Based on this information, the paper provides a comparison between the two ageing concepts, and discusses the philosophical inspirations which can be drawn for human ageing based on the operation of Evolutionary Algorithms.

  18. Basic concept on safety regulation for land disposal of low level radioactive solid wastes

    1985-01-01

    As to the land disposal of low level radioactive solid wastes, to which the countermeasures have become the urgent problem at present, it is considered to be a realistic method to finally store the solid wastes concentratedly outside the sites of nuclear power stations and others, and effort has been exerted by those concerned to realize it. Besides, as for extremely low level radioactive solid wastes, the measures of disposing them corresponding to the radioactivity level are necessary, and the concrete method has been examined. The Committee on Safety Regulation for Radioactive Wastes has discussed the safety regulation for those since April, 1984, and the basic concept on the safety regulation was worked up. It is expected that the safety of the land disposal of low level radioactive solid wastes can be ensured when the safety regulation is carried out in conformity with this basic concept. The present status of the countermeasures to the land disposal of low level radioactive solid wastes is shown. As the concrete method, the disposal in shallow strate has been generally adopted. At present, the plan for the final storage in Aomori Prefecture is considered, and it will be started with the first stage of four-stage control. (Kako, I.)

  20. THE MEANING IN THE CULTURE: BASIC CONCEPT TO ORGANIZATIONAL LEARNING

    ÁLVARO ENRÍQUEZ MARTÍNEZ

    2007-01-01

    Full Text Available Based on three key psychological concepts: learning, culture and meaning, the present essay proposes a conceptualbase frame, oriented toward the understanding of development in organizations into current milieu ofcompetitiveness and temporality, of the relationships among people working into them. The organizations whichare typically embedded in a context of values, needs and symbols that made up their cultures, must evolve in orderto face the demands for new developments and change, to which they are forced to. The concept of “meaning of theculture”, is presented as the base over which is build and rooted the organizational learning - in a technical and socialsense. The different types of learning are the ways in which the organizations satisfy the requirements coming fromtheir environments, in front of which must generate knowledge and consequently, new products and services,based on the people that form such organizations. The people that belong and constitutes the organization, incircumstances of temporal cohesion and within temporary working networks, must achieve results and to beadjusted to these new working and organizational facts, developing self-management and autonomy, in order tosignify and get adapted into the cultural tissue.

  2. Nonequilibrium thermodynamics and information theory: basic concepts and relaxing dynamics

    Altaner, Bernhard

    2017-01-01

    Thermodynamics is based on the notions of energy and entropy. While energy is the elementary quantity governing physical dynamics, entropy is the fundamental concept in information theory. In this work, starting from first principles, we give a detailed didactic account on the relations between energy and entropy and thus physics and information theory. We show that thermodynamic process inequalities, like the second law, are equivalent to the requirement that an effective description for physical dynamics is strongly relaxing. From the perspective of information theory, strongly relaxing dynamics govern the irreversible convergence of a statistical ensemble towards the maximally non-commital probability distribution that is compatible with thermodynamic equilibrium parameters. In particular, Markov processes that converge to a thermodynamic equilibrium state are strongly relaxing. Our framework generalizes previous results to arbitrary open and driven systems, yielding novel thermodynamic bounds for idealized and real processes. (paper)

  3. [Seed geography: its concept and basic scientific issues].

    Yu, Shun-Li; Wang, Zong-Shuai; Zeren, Wangmu

    2010-01-01

    In this paper, a new concept 'seed geography' was provided, and its definition, research contents, and scientific issues were put forward. Seed geography is a newly developed interdisciplinary science from plant geography, seed ecology, and phytosociology, which studies the geographic variation patterns of seed biological traits as well as their relationships with environmental factors from macroscopic to microscopic, and the seed formation, development, and change trends. The main research contents would include geography of seed mass, geography of seed chemical components, geography of seed morphology, geography of seed cell biological characteristics, geography of seed physiological characteristics, geography of seed genetic characteristics, and geography of flower and fruit. To explore the scientific issues in seed geography would help us to better understand the long-term adaptation and evolution of seed characteristics to natural environments.

  5. Coprecipitation of radionuclides: basic concepts, literature review and first applications

    Curti, E.

    1997-11-01

    Coprecipitation of radionuclides with solid products is currently not analysed quantitatively in safety assessments for nuclear waste repositories, although this process is thought to be an important mechanism for limiting nuclide concentrations in solution. This is due to the fact that neither the solid phases controlling coprecipitation nor the parameter values necessary to describe this process are known sufficiently. This introductory report provides basic knowledge on this subject and a review of experimental data from the literature. Emphasis is placed on experiments of trace metal coprecipitation with calcite, because this mineral is a dominating alteration product of cement in the Swiss L/ILW repository. This resulted in a database of partition coefficients, which allow to describe empirically the distribution of trace elements between calcite and solution and thus to quantify coprecipitation processes. Since laboratory data on coprecipitation with calcite are lacking for many safety-relevant radioelements, their partition coefficients were inferred with the help of estimation techniques. Such techniques rely on empirical correlations, which relate the uptake of trace metals in calcite (measured in laboratory tests) with selected chemical properties of the coprecipitated metals (e.g. ionic radius, sorption properties, solubility products of the pure trace metal carbonates). The combination of these correlations with independent geochemical evidence allows the extrapolation of radioelement-specific partition coefficients, which are then used for the quantitative modelling. In a first step the potential role of radionuclide coprecipitation during cement degradation in the L/ILW repository planned at Wellenberg is assessed. (author) figs., tabs., refs

  6. Spinal fusion-hardware construct: Basic concepts and imaging review

    Nouh, Mohamed Ragab

    2012-01-01

    The interpretation of spinal images fixed with metallic hardware forms an increasing bulk of daily practice in a busy imaging department. Radiologists are required to be familiar with the instrumentation and operative options used in spinal fixation and fusion procedures, especially in his or her institute. This is critical in evaluating the position of implants and potential complications associated with the operative approaches and spinal fixation devices used. Thus, the radiologist can play an important role in patient care and outcome. This review outlines the advantages and disadvantages of commonly used imaging methods and reports on the best yield for each modality and how to overcome the problematic issues associated with the presence of metallic hardware during imaging. Baseline radiographs are essential as they are the baseline point for evaluation of future studies should patients develop symptoms suggesting possible complications. They may justify further imaging workup with computed tomography, magnetic resonance and/or nuclear medicine studies as the evaluation of a patient with a spinal implant involves a multi-modality approach. This review describes imaging features of potential complications associated with spinal fusion surgery as well as the instrumentation used. This basic knowledge aims to help radiologists approach everyday practice in clinical imaging. PMID:22761979

  10. TERRITORIAL AND SPATIAL IDENTITY: NEW APPROARCH TO THE BASIC CONCEPTS

    I. Yu. Okunev

    2018-01-01

    Full Text Available Contrary to popular belief, the spatial aspect of political processes is  determined not only by objective factors. Space affects politics not  only directly, but also indirectly, through subjective and sometimes  distorted notions of space, formed by man. To study this subjective world, geography has its own terminology, some of which  are in dialectical connection with the concepts of «objective»  geography (territoriality vs. spatiality, absolute vs. relative space,  and some are unique for the discourse of this science (heterotopy,  spatial inversion, spatial experience, the place of memory, spatial  myth, and co-spatiality. The key to political geography is the notion of territorial and spatial identity, because they link ideas  about space with the political behavior of the individual. Recently,  the applied sphere of political geography has been actively  developing, based on the application of identity knowledge - territory branding based on place policy.

  11. Analysis of Students' Conceptions of Basic Magnetism from a Complex Systems Perspective

    Lemmer, Miriam; Kriek, Jeanne; Erasmus, Benita

    2018-03-01

    This study established whether 12 South African secondary school physics students had incorrect conceptions of basic magnetism and if they had, to what extent they consistently applied such conceptions. Different scenarios in the form of thought experiments were presented in a clinical interview approach. A complex systems perspective underpinned the study and was firstly used to analyze 12 students' conceptions in terms of intuitive fragments of knowledge elements, structured misconceptions, and theory-like system of knowledge elements. Secondly, coherence in each student's ideas expressed across ten themes using thought experiments was analyzed in an effort to determine variations or coherence in responses. Examples of student explanations and sketches are discussed in the paper to illustrate the conceptual structures they applied. Most of the students in this study used a variety of knowledge elements in accord with a complex systems perspective, but three students seemed to prefer a specific perspective. One student's ideas tended to be mainly fragmented, a second exposed a number of structured misconceptions, while another student's reasoning can be described as a theory-like system of knowledge elements. Accordingly, the emphasis of physics education research should no longer be on the compilation of a list of misconceptions that have to be remedied or replaced, but on the conceptual connections, students make and their associative reasoning patterns (i.e., knowledge systems revealed). It remains for the teacher to use the complex systems perspective as a framework to facilitate students' conceptual development and understanding, proceeding on their existing knowledge systems.

  12. a Discussion about Effective Ways of Basic Resident Register on GIS

    Oku, Naoya; Nonaka, Yasuaki; Ito, Yutaka

    2016-06-01

    In Japan, each municipality keeps a database of every resident's name, address, gender and date of birth called the Basic Resident Register. If the address information in the register is converted into coordinates by geocoding, it can be plotted as point data on a map. This would enable prompt evacuation from disaster, analysis of distribution of residents, integrating statistics and so on. Further, it can be used for not only analysis of the current situation but also future planning. However, the geographic information system (GIS) incorporating the Basic Resident Register is not widely used in Japan because of the following problems: - Geocoding In order to plot address point data, it is necessary to match the Basic Resident Register and the address dictionary by using the address as a key. The information in the Basic Resident Register does not always match the actual addresses. As the register is based on applications made by residents, the information is prone to errors, such as incorrect Kanji characters. - Security policy on personal information In the register, the address of a resident is linked with his/her name and date of birth. If the information in the Basic Resident Register were to be leaked, it could be used for malicious purposes. This paper proposes solutions to the above problems. The suitable solutions for the problems depend on the purpose of use, thus it is important that the purpose should be defined and a suitable way of the application for each purpose should be chosen. In this paper, we mainly focus on the specific purpose of use: to analyse the distribution of the residents. We provide two solutions to improve the matching rate in geocoding. First, regarding errors in Kanji characters, a correction list of possible errors should be compiled in advance. Second, some sort of analyses such as distribution of residents may not require exactly correct position for the address point. Therefore we set the matching level in order: prefecture

  17. Adiabatic invariants in stellar dynamics. 1: Basic concepts

    Weinberg, Martin D.

    1994-01-01

    The adiabatic criterion, widely used in astronomical dynamics, is based on the harmonic oscillator. It asserts that the change in action under a slowly varying perturbation is exponentially small. Recent mathematical results that precisely define the conditions for invariance show that this model does not apply in general. In particular, a slowly varying perturbation may cause significant evolution stellar dynamical systems even if its time scale is longer than any internal orbital time scale. This additional 'heating' may have serious implications for the evolution of star clusters and dwarf galaxies which are subject to long-term environmental forces. The mathematical developments leading to these results are reviewed, and the conditions for applicability to and further implications for stellar systems are discussed. Companion papers present a computational method for a general time-dependent disturbance and detailed example.

  18. Adaptive fractionation therapy: I. Basic concept and strategy

    Lu Weiguo; Chen Mingli; Chen Quan; Ruchala, Kenneth; Olivera, Gustavo

    2008-01-01

    Radiotherapy is fractionized to increase the therapeutic ratio. Fractionation in conventional treatment is determined as part of the prescription, and a fixed fraction size is used for the whole course of treatment. Due to patients' day-to-day variations on the relative distance between the tumor and the organs at risk (OAR), a better therapeutic ratio may be attained by using an adaptive fraction size. Intuitively, we want to use a larger fraction size when OAR and the tumor are far apart and a smaller fraction size when OAR and the tumor are close to each other. The concept and strategies of adaptive fractionation therapy (AFT) are introduced in this paper. AFT is an on-line adaptive technique that utilizes the variations of internal structures to get optimal OAR sparing. Changes of internal structures are classified as different configurations according to their feasibility to the radiation delivery. A priori knowledge is used to describe the probability distribution of these configurations. On-line processes include identifying the configuration via daily image guidance and optimizing the current fraction size. The optimization is modeled as a dynamic linear programming problem so that at the end of the treatment course, the tumor receives the same planned dose while OAR receives less dose than the regular fractionation delivery. Extensive simulations, which include thousands of treatment courses with each course consisting of 40 fractions, are used to test the efficiency and robustness of the presented technique. The gains of OAR sparing depend on the variations on configurations and the bounds of the fraction size. The larger the variations and the looser the bounds are, the larger the gains will be. Compared to the conventional fractionation technique with 2 Gy/fraction in 40 fractions, for a 20% variation on tumor-OAR configurations and [1 Gy, 3 Gy] fraction size bounds, the cumulative OAR dose with adaptive fractionation is 3-8 Gy, or 7-20% less than that

  2. The Concept of Basic Income: Global Experience and Implementation Possibilities in Lithuania

    Algimantas Laurinavičius

    2016-06-01

    Full Text Available The article gives an overview of universal basic income as one of the instruments of the asset-based policy, analyses its theoretical concept and practical examples. Latest trends in Europe, especially in Finland and Switzerland, are overviewed and possibilities to implement such an instrument in Lithuania are evaluated. Research methods of scientific literature analysis, comparative and logical analysis of statistical data, data grouping and presentation were used. Article finds out that the concept of basic income is being implemented on a small scale in the US state of Alaska and in a small autonomous territory of China – Macao. Finland and Switzerland are determined to fully implement the concept of basic income by providing monthly benefits to all their citizens. Although Lithuania is categorized as a country with high income inequality and high level of poverty risk, currently it is not possible to implement the concept of basic income in Lithuania: the state social insurance fund budget would not be able to fund sufficient benefits, and the benefits that could be provided by the budget would not comply with the objectives of the concept of basic income.

  20. The nursing profession: public image, self-concept and professional identity. A discussion paper.

    ten Hoeve, Yvonne; Jansen, Gerard; Roodbol, Petrie

    2014-02-01

    To discuss the actual public image of nurses and other factors that influence the development of nurses' self-concept and professional identity. Nurses have become healthcare professionals in their own right who possess a great deal of knowledge. However, the public does not always value the skills and competences nurses have acquired through education and innovation. Discussion paper. We identified 1216 relevant studies by searching MEDLINE, CINAHL and PsycINFO databases in the period 1997-2010. Finally, 18 studies met our inclusion criteria. The included studies show that the actual public image of nursing is diverse and incongruous. This image is partly self-created by nurses due to their invisibility and their lack of public discourse. Nurses derive their self-concept and professional identity from their public image, work environment, work values, education and traditional social and cultural values. Nurses should work harder to communicate their professionalism to the public. Social media like the Internet and YouTube can be used to show the public what they really do. To improve their public image and to obtain a stronger position in healthcare organizations, nurses need to increase their visibility. This could be realized by ongoing education and a challenging work environment that encourages nurses to stand up for themselves. Furthermore, nurses should make better use of strategic positions, such as case manager, nurse educator or clinical nurse specialist and use their professionalism to show the public what their work really entails. © 2013 John Wiley & Sons Ltd.

  1. Discussion on the concepts of "coordination" and "agility" in terms of physical education

    V.A. Zaporozhanov

    2015-03-01

    Full Text Available In the scientific and methodological literature and practice of physical education concepts of "coordination" and "agility" are often used synonymously. And discussion about the appropriateness distinguish these concepts is mainly analytical character. Purpose : to evaluate the nature of the relationship metrically between indicators kinesthesia (which characterize the internal processes of interaction in the neuro-muscular system - coordination and the efficient delivery of a complex exercise (in cooperation man in the external environment of physical education - agility. Material : 77 students surveyed. Students performed on 100 strikes the ball into the goal in terms of golf (10 control measurements. The experiment was conducted for 8 months. 7700 measurement precision of centimeters processed statistically. Calculated reliability of measurements: 100 comparability repetitive beats, accuracy hitting the ball into the goal and the pace of learning in terms of the impact of blows. Results : the total volume measurements was characterized by high variability (V% = 53,5, indicating that the low status of kinesthesia surveyed. This reduces the reliability of the correlation coefficients according to 30 and then 10 of the best students in the general rank in terms of reliability of measurements. Significant correlation occurred only in terms of performance beats the purpose of learning the technique and pace (0,417; n = 30, p <0,05; and 0,677; n = 10, p <0,05. Conclusions : Overall, the results of our study showed that the concept of "coordination" and "agility" should still be distinguished. In some cases, students with a good level of kinesthesia occurred and high mobility in complex locomotion. If we recognize it expedient to continue this discussion, then we must rely on objective, metric information. This information should be obtained in studies with a broad contingent surveyed, consistently show good concentration and high reliability

  2. Basic concept of fuel safety design and assessment for sodium-cooled fast reactor

    Nakae, Nobuo; Baba, Toshikazu; Kamimura, Katsuichiro

    2013-03-01

    'Philosophy in Safety Evaluation of Fast Breeder Reactors' was published as a guideline for safety design and safety evaluation of Sodium-Cooled Fast Reactor in Japan. This guideline points out that cladding creep and swelling due to internal pressure should be taken into account since the fuel is used under high temperature and high burnup, and that fuel assembly deformation and the prevention from coolant channel blockage should be taken into account in viewpoints of nuclear and thermal hydraulic design. However, the requirements including their criteria and evaluation items are not described. Two other domestic guidelines related to core design are applied for fuel design of fast reactor, but the description is considered to not be enough to practically use. In addition, technical standard for nuclear fuel used in power reactors is also applied for fuel inspection. Therefore, the technical standard and guideline for fuel design and safety evaluation are considered to be very important issue for nuclear safety regulation. This document has been developed according to the following steps: The guidelines and the technical standards, which are prepared in foreign countries and international organization, were reviewed. The technical background concerning fuel design and safety evaluation for fast reactor was collected and summarized in the world wide scale. The basic concept of fuel safety design and assessment for sodium-cooled fast reactor was developed by considering a wide range of views of the specialists in Japan. In order to discuss the content with foreign specialists IAEA Consultancy Meetings have been held on January, 2011 and January, 2012. The participants of the meeting came from USA, UK, EC, India, China and South Korea. The specialists of IAEA and JNES were also joined. Although this document is prepared for application to 'Monju'(prototype LMFR), it may be applied to experimental, demonstration and commercial types of LMFR after revising it by taking

  3. Basic concepts in dosimetry. A critical analysis of the concepts of ionizing radiation and energy imparted

    Carlson, G.A.

    1978-01-01

    The concepts of ionizing radiation and energy imparted defined by the ICRU in 1971 (Radiation Quantities and Units, Report 19, International Commission on Radiation Units and Measurements, Washington, D.C., 1971) are critically analyzed. It is found that the definitions become more consistent by changing them at two points. Charged particles with insufficient kinetic energy to ionize by collision but which are capable of initiating nuclear and elementary particle transformations are suggested to be classified as ionizing particles. In addition, the expressions ''the energy released'' or the ''energy expended'' in a nuclear or elementary particle transformation are suggested to be specified as ''the change in rest-mass energy of nuclei and elementary particles.'' Then the ionization caused by, for instance, nuclear reactions contributes to the energy imparted and the Q-value of an excitation or deexcitation of the electron structure, regarded as an elementary particle transformation, is zero

  4. Three Short Films about Water: Presenting Basic Concepts to Students and Stakeholders

    Arrigo, J. S.; Hooper, R. P.; Michel, A.; Wilde, P.; Lilienfeld, L.

    2011-12-01

    Three short form (3 - 5 minute) movies were produced for CUAHSI, to convey basic concepts such as a hydrologic budget, stores and fluxes of water, and the flowpaths and residence time of water. The films were originally intended to be used by scientists to explain the concepts behind potential environmental observatories, but evolved into serving a broader purpose. The films combine still photos, satellite images, animation and video clips, and interviews with CUAHSI members explaining hydrologic concepts in simple, accessible terms. In producing these films, we have found the importance of engaging scientists in conversation first, to develop a script around key accessible concepts and relevant information. Film and communication professionals play a critical role in distilling the scientific explanation and concepts into accessible, engaging film material. The films have been widely distributed through CD and online to educators for use in courses. Additionally, they provide a way to engage stakeholders, particularly land owners, by conveying basic concepts that are necessary to understand the hydrologic and earth science foundation of many of today's political and environmental issues. The films can be viewed online at the CUAHSI website, which also contains links to other film related resources and programs.

  5. The Mediational Role of Psychological Basic Needs in the Relation Between Conception of God and Psychological Outcomes.

    Costa, Sebastiano; Gugliandolo, Maria C; Barberis, Nadia; Larcan, Rosalba

    2016-02-01

    Relatively few studies have examined the relationship between conception of God and psychological outcomes in a self-determination theory (SDT) framework. The aim of this study was to examine the role of basic psychological needs as a mediator of the association between conception of God and psychological outcomes. In a sample of 210 religious young adults, we found that the concept of a controlling God was positively associated with feelings of need frustration and depression, whilst the concept of an autonomy-supporting God was positively associated with feelings of need satisfaction and vitality. In turn, need satisfaction promoted feelings of vitality, whereas need frustration led to feelings of depression. The satisfaction of needs was a full mediator of the relationship between autonomy-supporting God and vitality, whilst the frustration of needs was a full mediator of the relationship between controlling God and depression. These findings are discussed in terms of SDT. We also discuss how future research may further increase our understanding of the dynamics involved in concepts of God and psychological outcomes.

  6. Self-Concept and Sport Participation in Sixth Grade Basic School Students

    Špela Virag

    2016-04-01

    Full Text Available The purpose of the study was to examine self-concept in relation to sport participation among basic school children. The sample included 109 sixth grade students of different Slovenian basic schools. The participants completed the Slovenian version of the SelfPerception Profile for Children – SPPC. The results show significant gender differences in some specific components of self-concept. Boys exhibited higher scores in perceived physical appearance and athletic competence, whereas girls exhibited higher levels in perceived behavioural conduct. Mean values show that students, engaged in organized sport practice, reported higher scores in all self-concept subscales than their inactive peers, although significant differences between these two groups were found in perceived scholastic competence and athletic competence. The study offers a detailed insight into the multidimensional self-perceptions of sixth grade basic school students. The results highlight the importance of physical/sports activity in the self-concept development and can be useful in promoting an active lifestyle among youth.

  10. Basic Concepts in G-Protein-Coupled Receptor Homo- and Heterodimerization

    Rafael Franco

    2007-01-01

    Full Text Available Until recently, heptahelical G-protein-coupled receptors (GPCRs were considered to be expressed as monomers on the cell surface of neuronal and non-neuronal cells. It is now becoming evident that this view must be overtly changed since these receptors can form homodimers, heterodimers, and higher-order oligomers on the plasma membrane. Here we discuss some of the basics and some new concepts of receptor homo- and heteromerization. Dimers-oligomers modify pharmacology, trafficking, and signaling of receptors. First of all, GPCR dimers must be considered as the main molecules that are targeted by neurotransmitters or by drugs. Thus, binding data must be fitted to dimer-based models. In these models, it is considered that the conformational changes transmitted within the dimer molecule lead to cooperativity. Cooperativity must be taken into account in the binding of agonists-antagonists-drugs and also in the binding of the so-called allosteric modulators. Cooperativity results from the intramolecular cross-talk in the homodimer. As an intramolecular cross-talk in the heterodimer, the binding of one neurotransmitter to one receptor often affects the binding of the second neurotransmitter to the partner receptor. Coactivation of the two receptors in a heterodimer can change completely the signaling pathway triggered by the neurotransmitter as well as the trafficking of the receptors. Heterodimer-specific drugs or dual drugs able to activate the two receptors in the heterodimer simultaneously emerge as novel and promising drugs for a variety of central nervous system (CNS therapeutic applications.

  15. Multidimensional Generalized Functions in Aeroacoustics and Fluid Mechanics. Part 1; Basic Concepts and Operations

    Farassat, Fereidoun; Myers, Michael K.

    2011-01-01

    This paper is the first part of a three part tutorial on multidimensional generalized functions (GFs) and their applications in aeroacoustics and fluid mechanics. The subject is highly fascinating and essential in many areas of science and, in particular, wave propagation problems. In this tutorial, we strive to present rigorously and clearly the basic concepts and the tools that are needed to use GFs in applications effectively and with ease. We give many examples to help the readers in understanding the mathematical ideas presented here. The first part of the tutorial is on the basic concepts of GFs. Here we define GFs, their properties and some common operations on them. We define the important concept of generalized differentiation and then give some interesting elementary and advanced examples on Green's functions and wave propagation problems. Here, the analytic power of GFs in applications is demonstrated with ease and elegance. Part 2 of this tutorial is on the diverse applications of generalized derivatives (GDs). Part 3 is on generalized Fourier transformations and some more advanced topics. One goal of writing this tutorial is to convince readers that, because of their powerful operational properties, GFs are absolutely essential and useful in engineering and physics, particularly in aeroacoustics and fluid mechanics.

  16. A discussion of current issues and concepts in the practice of skull-photo/craniofacial superimposition.

    Gordon, G M; Steyn, M

    2016-05-01

    A recent review paper on cranio-facial superimposition (CFS) stated that "there have been specific conceptual variances" from the original methods used in the practice of skull-photo superimposition, leading to poor results as far as accuracy is concerned. It was argued that the deviations in the practice of the technique have resulted in the reduced accuracies (for both failure to include and failure to exclude) that are noted in several recent studies. This paper aims to present the results from recent research to highlight the advancement of skull-photo/cranio-facial superimposition, and to discuss some of the issues raised regarding deviations from original techniques. The evolving methodology of CFS is clarified in context with the advancement of technology, forensic science and specifically within the field of forensic anthropology. Developments in the skull-photo/cranio-facial superimposition techniques have largely focused on testing reliability and accuracy objectively. Techniques now being employed by forensic anthropologists must conform to rigorous scientific testing and methodologies. Skull-photo/cranio-facial superimposition is constantly undergoing accuracy and repeatability testing which is in line with the principles of the scientific method and additionally allows for advancement in the field. Much of the research has indicated that CFS is useful in exclusion which is consistent with the concept of Popperian falsifiability - a hypothesis and experimental design which is falsifiable. As the hypothesis is disproved or falsified, another evolves to replace it and explain the new observations. Current and future studies employing different methods to test the accuracy and reliability of skull-photo/cranio-facial superimposition will enable researchers to establish the contribution the technique can have for identification purposes.

  1. Berimbau: A simple instrument for teaching basic concepts in the physics and psychoacoustics of music

    Vilão, Rui C.; Melo, Santino L. S.

    2014-12-01

    We address the production of musical tones by a simple musical instrument of the Brazilian tradition: the berimbau-de-barriga. The vibration physics of the string and of the air mass inside the gourd are reviewed. Straightforward measurements of an actual berimbau, which illustrate the basic physical phenomena, are performed using a PC-based "soundcard oscilloscope." The inharmonicity of the string and the role of the gourd are discussed in the context of known results in the psychoacoustics of pitch definition.

  3. Basic Concepts in the Taxonomy of Health-Related Behaviors, Habits and Lifestyle

    Salvador-Carulla, Luis; Alonso, Federico; Gomez, Rafael; Walsh, Carolyn O.; Almenara, José; Ruiz, Mencía; Abellán, María José

    2013-01-01

    Background: Health-related Habits (HrH) are a major priority in healthcare. However there is little agreement on whether exercise, diet, smoking or dental hygiene are better described as lifestyles, habits or behaviors, and on what is their hierarchical relationship. This research is aimed at representing the basic concepts which are assumed to constitute the conceptual framework enabling us to interpret and organize the field of HrH. Methods: A group of 29 experts with different backgrounds agreed on the definition and hierarchy of HrH following an iterative process which involved framing analysis and nominal group techniques. Results: Formal definitions of health-related behavior, habit, life-style and life-style profile were produced. In addition a series of basic descriptors were identified: health reserve, capital, risk and load. Six main categories of HrH were chosen based on relevance to longevity: diet/exercise, vitality/stress, sleep, cognition, substance use and other risk. Attributes of HrH are clinical meaningfulness, quantifiability, temporal stability, associated morbidity, and unitarity (non-redundancy). Two qualifiers (polarity and stages of change) have also been described. Conclusions: The concepts represented here lay the groundwork for the development of clinical and policy tools related to HrH and lifestyle. An adaptation of this system to define targets of health interventions and to develop the classification of person factors in ICF may be needed in the future. PMID:23670578

    Full Text Available This research was conducted in order to examine the subject matter of Mathematics teachers in the context of "Mathematical Knowledge For Teaching" (MKT model of "Basic Concepts in Sets" which is the first topic of the 9th class "Sets". The study group, which is one of the qualitative research methods, used the case study design, constitutes 5 mathematics teachers who work in different education levels (primary and secondary education in the academic year of 2015-2016. Open-ended questions and semi-structured interview form developed by the researcher were used for data collection. A descriptive analysis technique was used to analyze the data obtained through interviews. While analyzing the data, teacher and student textbooks, which were prepared by the Ministry of National Education for the purpose of teaching in 2015-2016 academic year, were taken as a reference. According to the research findings, it was determined that the teachers had deficiencies in the subject field of "Basic Concepts in the Sets" and had superficial knowledge rather than in depth knowledge.

  6. The conception of disability under discussion: the point of view of Occupational Therapy professors

    Luciana Ramos Baleotti

    2014-04-01

    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.

  7. A discussion supporting presumed consent for posthumous sperm procurement and conception.

    Tremellen, Kelton; Savulescu, Julian

    2015-01-01

    Conception of a child using cryopreserved sperm from a deceased man is generally considered ethically sound provided explicit consent for its use has been made, thereby protecting the man's autonomy. When death is sudden (trauma, unexpected illness), explicit consent is not possible, thereby preventing posthumous sperm procurement (PSP) and conception according to current European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine guidelines. Here, we argue that autonomy of a deceased person should not be considered the paramount ethical concern, but rather consideration of the welfare of the living (widow and prospective child) should be the primary focus. Posthumous conception can bring significant advantages to the widow and her resulting child, with most men supporting such practice. We suggest that a deceased man can benefit from posthumous conception (continuation of his 'bloodline', allowing his widow's wishes for a child to be satisfied), and has a moral duty to allow his widow access to his sperm, if she so wishes, unless he clearly indicated that he did not want children when alive. We outline the arguments favouring presumed consent over implied or proxy consent, plus practical considerations for recording men's wishes to opt-out of posthumous conception.

  8. The Concept of a Single-sex Optional Discussion Session in Introductory Astronomy at a Publicly Funded University

    Shawl, S.

    1996-12-01

    The concept of single-sex education for science and mathematics has recently received renewed discussion in both the popular and professional literature. So important is the topic within higher education that the Duke Journal of Gender Law and Policy sponsored a symposium called "Gender & The Higher Education Classroom: Maximizing the Learning Environment" in February 1996 (http://www.duke.edu/ jrd4/djgcnf96.htm). The concept is especially controversial in publicly supported educational institutions. The idea of offering an optional discussion session limited to a single sex in a university-level introductory astronomy course at a State-supported school was considered through discussions with a number of faculty and administrators, and through a questionnaire aimed at determining student attitudes toward the concept. The results of the student questionnaire will be presented. (While the questionnaire results will be seen to be in favor of such an optional discussion session, such sessions have not been offered.)

  9. [Discussion on ideological concept implied in traditional reinforcing and reducing method of acupuncture].

    Li, Suyun; Zhao, Jingsheng

    2017-11-12

    The forming and development of traditional reinforcing and reducing method of acupuncture was rooted in traditional culture of China, and was based on the ancients' special understanding of nature, life and diseases, therefore its principle and methods were inevitably influenced by philosophy culture and medicine concept at that time. With deep study on Inner Canon of Huangdi and representative reinforcing and reducing method of acupuncture, the implied ideological concept, including contradiction view and profit-loss view in ancient dialectic, yin-yang balance theory, concept of life flow, monophyletic theory of qi , theory of existence of disease-evil, yin - yang astrology theory, theory of inter-promotion of five elements, were summarized and analyzed. The clarified and systematic understanding on guiding ideology of reinforcing and reducing method of acupuncture could significantly promote the understanding on principle, method, content and manipulation.

  10. The implication of the concept “nikotiiniriippuvuus” in the Finnish tobacco discussion

    Hellman Matilda

    2014-12-01

    Full Text Available BACKGROUND - We examined the Finnish concept of “nikotiiniriippuvuus” (nicotine addiction or dependency in English in two public arenas in recent Finnish history (1970s, 1990s and 2000s. One was the biggest daily newspaper Helsingin Sanomat, the other the medical professional journal Lääkärilehti. DATA & DESIGN - A total of 102 print press items from the 1990s and the 2000s were collected through electronic archives with the search word “nikotiiniriippuvuus”. In addition, 41 texts were collected manually from the 1970s. RESULTS - Of the items from the 1970s, only three mentioned the concept of “riippuvuus”. Overall, we found that the use of “nikotiiniriippuvuus” has increased greatly over time. In order to know more about the implications of this, we identified some themes as meaning-making traits surrounding the concept in the materials. The analysis points to four main meaning-making functions of the concept: i agenda-setting, ii introducing and explaining self-governance techniques, iii introducing a medical understanding, and iv, mediating views on responsibility division.

  12. When and how should we teach the basic concepts of radiation beam dosage

    Brewin, T B [Institute of Radiotherapeutics and Oncology, Glasgow (UK)

    1977-06-01

    The difficulty that many trainees, including those medically qualified, have in achieving a sound working grasp of certain basic principles of radiation beam dosage is often underestimated. Since any failure of understanding may seriously impair the efficiency of the team treating the patient, the discussion of these problems (and especially the monitoring of the results of such discussion by means of oral and written tests) deserves a high priority. Contrary to traditional practice, there would seem to be no good reason why teaching of radiation beam dosage, and the effect on dose-rate of changes in the treatment distance or in the amount of scattered radiation, should not begin in the very first week of training and be immediately integrated with discussion of the dose-rate information available at every radiotherapy unit when the patient is treated. A preliminary course of physics lectures does not usually make the understanding of these principles any easier and can be done either concurrently or later. For many radiotherapy trainees and for many doctors in other fields, comparison with drug dosage and with the brightness and scatter of ordinary light beams, avoiding technical terms so far as possible, may achieve a better initial understanding of basic principles than is achieved by mathematical equations and theoretical physics.

  14. A new look at some basic concepts in arbitrage pricing theory

    XIA; Jianming(夏建明); YAN; Jia'an(严加安)

    2003-01-01

    The notion of No Free Lunch with Vanishing Risk (or NFLVR in short) w.r.t. admissible strategies depends on the choice of numeraire. Yan introduced the notion of allowable strategy and showed that condition of NFLVR w.r.t. allowable strategies is independent of the choice of numeraire and is equivalent to the existence of an equivalent martingale measure for the deflated price process. In this paper we establish a version of the Kramkov's optional decomposition theorem in the setting of equivalent martingale measures. Based on this theorem, we have a new look at some basic concepts in arbitrage pricing theory: superhedging, fair price,attainable contingent claims, complete markets and etc.

  15. Diffusion-weighted imaging: basic concepts and application in cerebral stroke and head trauma

    Huisman, Thierry A.G.M.

    2003-01-01

    Diffusion-weighted imaging (DWI) of the brain represents a new imaging technique that extends imaging from depiction of neuroanatomy to the level of function and physiology. DWI measures a fundamentally different physiological parameter compared with conventional MRI. Image contrast is related to differences in the diffusion rate of water molecules rather than to changes in total tissue water. DWI can reveal pathology in cases where conventional MRI remains unremarkable. DWI has proven to be highly sensitive in the early detection of acute cerebral ischemia and seems promising in the evaluation of traumatic brain injury. DWI can differentiate between lesions with decreased and increased diffusion. In addition, full-tensor DWI can evaluate the microscopic architecture of the brain, in particular white matter tracts, by measuring the degree and spatial distribution of anisotropic diffusion within the brain. This article reviews the basic concepts of DWI and its application in cerebral ischemia and traumatic brain injury. (orig.)

    Hovenier, Joop W; Domke, Helmut

    2004-01-01

    The principal elements of the theory of polarized light transfer in planetary atmospheres are expounded in a systematic but concise way. Basic concepts and practical methods are emphasized, both for single and multiple scattering of electromagnetic radiation by molecules and particles in the atmospheres of planets in the Solar System, including the Earth, and beyond. A large part of the book is also useful for studies of light scattering by particles in comets, the interplanetary and interstellar medium, circumstellar disks, reflection nebulae, water bodies like oceans and suspensions of particles in a gas or liquid in the laboratory. Throughout the book symmetry principles, such as the reciprocity principle and the mirror symmetry principle, are employed. In this way the theory is made more transparent and easier to understand than in most papers on the subject. In addition, significant computational reductions, resulting from symmetry principles, are presented. Hundreds of references to relevant literature ...

  18. Basic conception of simultaneous multi-layer hybrid type ECT apparatus 'HEADTOME-2'

    Nakanishi, Shigemasa

    1981-01-01

    Following on the one-slice hybrid type ECT (emission computer tomography) apparatus HEADTOME-1 for the measurement of local cerebral blood stream by single-photon measurement and the measurement of local cerebral metabolism by positron measurement, the development of the simultaneous multi-layer hybrid type ECT apparatus HEADTOME-2 was started for the simultaneous measurement of whole brains. Being designed also for obtaining single-photon simultaneous multi-layer tomography, a peculiar mode of collimator structure was employed, thereby the defect in HEADTOME-1 was eliminated. The design of the detector section is as follows: detector array diameter 42 cm, effective vision-field diameter 21 cm, patient tunnel diameter 25 cm, detector rings 3, slice interval 35 cm, and NaI (Tl) crystals 64 per layer. The basic conception of HEADTOME-2, such as the detectors, collimator, the number of slices, specifications, and data processing system, is described. (J.P.N.)

  2. Structural equation modeling with LISREL, PRELIS, and SIMPLIS basic concepts, applications, and programming

    Byrne, Barbara M

    2013-01-01

    This book illustrates the ease with which various features of LISREL 8 and PRELIS 2 can be implemented in addressing research questions that lend themselves to SEM. Its purpose is threefold: (a) to present a nonmathmatical introduction to basic concepts associated with SEM, (b) to demonstrate basic applications of SEM using both the DOS and Windows versions of LISREL 8, as well as both the LISREL and SIMPLIS lexicons, and (c) to highlight particular features of the LISREL 8 and PRELIS 2 progams that address important caveats related to SEM analyses. This book is intended neither as a text on the topic of SEM, nor as a comprehensive review of the many statistical funcitons available in the LISREL 8 and PRELIS 2 programs. Rather, the intent is to provide a practical guide to SEM using the LISREL approach. As such, the reader is "walked through" a diversity of SEM applications that include both factor analytic and full latent variable models, as well as a variety of data management procedures.

    2016-05-01

    Full Text Available Social Media has become an important source for information about people and real-world events. Its importance is driven largely by the enormous number of people generating and updating content in Social Media platforms. In this report, we measure the extent to which we can accurately measure the salience of topics/concepts that might be of interest to an analyst, and evaluate whether concepts like positive and negative sentiment can be meaningfully extracted from Social Media content. As a test case, we examined Twitter content generated by female users who are sympathetic to the Islamic State in Iraq and Syria (ISIS. The basic technique proposed here can be developed further to create a more fine-grained exanimation of Social Media content.

  5. Revisiting the Basic Symptom Concept: Towards Translating Risk Symptoms for Psychosis into Neurobiological Targets

    Frauke eSchultze-Lutter

    2016-01-01

    Full Text Available In its initial formulation, the concept of basic symptoms (BSs integrated findings on the early symptomatic course of schizophrenia and first in vivo evidence of accompanying brain aberrations. It argued that the subtle subclinical disturbances in mental processes described as BSs were the most direct self-experienced expression of the underlying neurobiological aberrations of the disease. Other characteristic symptoms of psychosis (e.g., delusions, hallucinations were conceptualized as secondary phenomena, resulting from dysfunctional beliefs and suboptimal coping styles with emerging BSs and/or concomitant stressors. While BSs can occur in many mental disorders, in particular affective disorders, a subset of perceptive and cognitive BSs appear to be specific to psychosis and are currently employed in two alternative risk criteria. However, despite their clinical recognition in the early detection of psychosis, neurobiological research on the aetiopathology of psychosis with neuroimaging methods has only just begun to consider the neural correlate of BSs. This perspective paper reviews the emerging evidence of an association between BSs and aberrant brain activation, connectivity patterns, and metabolism, and outlines promising routes for the use of BSs in aetiopathological research on psychosis.

  6. A Unified Discussion on the Concept of Score Functions Used in the Context of Nonparametric Linkage Analysis

    Lars Ängquist

    2008-01-01

    Full Text Available In this article we try to discuss nonparametric linkage (NPL score functions within a broad and quite general framework. The main focus of the paper is the structure, derivation principles and interpretations of the score function entity itself. We define and discuss several families of one-locus score function definitions, i.e. the implicit, explicit and optimal ones. Some generalizations and comments to the two-locus, unconditional and conditional, cases are included as well. Although this article mainly aims at serving as an overview, where the concept of score functions are put into a covering context, we generalize the noncentrality parameter (NCP optimal score functions in Ängquist et al. (2007 to facilitate—through weighting—for incorporation of several plausible distinct genetic models. Since the genetic model itself most oftenly is to some extent unknown this facilitates weaker prior assumptions with respect to plausible true disease models without loosing the property of NCP-optimality. Moreover, we discuss general assumptions and properties of score functions in the above sense. For instance, the concept of identical by descent (IBD sharing structures and score function equivalence are discussed in some detail.

  7. The concepts of exclusion, exemption and clearance as used in the interagency basic safety standards and related IAEA documents

    Webbl, G.A.M.

    1997-01-01

    Mechanisms are needed to remove from regulatory control those exposures or radiation sources that do not warrant concern. In this paper three such conceptual mechanisms are examined from their historical development to their current usage in the Interagency Basic Safety Standards. These concepts are exclusion, applied to exposures that are not amenable to control, exemption applied in advance on the basis of low risks to prevent practices or sources from entering the regulatory control system, and clearance, a similar concept but used to remove sources from the regulatory control system. The application of and interrelationships between these concepts, is described. (author)

  9. Ab initio molecular dynamics: basic concepts, current trends and novel applications

    Tuckerman, Mark E

    2002-01-01

    The field of ab initio molecular dynamics (AIMD), in which finite temperature molecular dynamics (MD) trajectories are generated with forces obtained from accurate 'on the fly' electronic structure calculations, is a rapidly evolving and growing technology that allows chemical processes in condensed phases to be studied in an accurate and unbiased way. This article is intended to present the basics of the AIMD method as well as to provide a broad survey of the state of the art of the field and showcase some of its capabilities. Beginning with a derivation of the method from the Born-Oppenheimer approximation, issues including the density functional representation of electronic structure, basis sets, calculation of observables and the Car-Parrinello extended Lagrangian algorithm are discussed. A number of example applications, including liquid structure and dynamics and aqueous proton transport, are presented in order to highlight some of the current capabilities of the approach. Finally, advanced topics such as inclusion of nuclear quantum effects, excited states and scaling issues are addressed. (topical review)

  10. Ethics of genetic counseling--basic concepts and relevance to Islamic communities.

    El-Hazmi, Mohsen A F

    2004-01-01

    Scientific advances and technical developments in the field of laboratory diagnosis and their practical applications have raised ethical issues linked to religion, beliefs, lifestyle and traditions prevailing in different communities. Some of these are pertinent to genetic screening at various stages of life, prenatal diagnosis and the right of the genetically affected fetus to live--all aspects relevant to inbreeding marriages. Of relevance are medical and ethical principles based on professional responsibility. These ideological and social aspects encounter the challenges of science and its applications in the health field, which are linked, directly or indirectly, to scientific achievements and applications related to human genetics. Analysis of the human genome and identification of its sequence, and chemical components, and theories arising from connection of human genome components in health and disease conditions, have led to global requirements to outline legal aspects and ethical principles in relation to diagnosis, prevention and health care. This paper presents basic aspects of disseminating genetic information, guiding the individual, the couple, or the concerned family through genetically induced ill health and methods of control and prevention. The paper discusses the elements and manner and presents details of the application of genetic counseling in Islamic communities in light of scientific, religious, social and legal aspects in the Islamic arena.

  11. Wavelet basics

    Chan, Y T

    1995-01-01

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames. Chapter 2 introduces the wavelet transform, contrasts it with the short-time Fourier transform and clarifies the names of the different types of wavelet transforms. Chapter 3 links multiresolution analysis, orthonormal wavelets and the design of digital filters. Chapter 4 gives a tour d'horizon of topics of current interest: wave...

  12. BASIC CONCEPTS AND METHODS OF RESTORATION OF NATURAL FORESTS IN EASTERN EUROPE

    V. N. Korotkov

    2017-03-01

    Full Text Available The modern forest in coniferous-broadleaf (hemiboreal and broadleaf zones of Eastern Europe were formed as a result of long-term human impact. This led to the loss of natural forests and total dominance of secondary forests combined with monocultures of spruce and pine that were created in clearings, burned areas and fallow lands. The reforestation model that was common in the late XIX and first half of the XX century and that was focused on the establishment of monocultures commercially valuable coniferous tree species (spruce and pine over large areas has resulted in declining biological diversity, increasing risk of tree damage due to outbreaks of pathogens and phytophagous insects, decreasing soil fertility, worsening soil and water conservation functions of forests. When restoring the prototypes of natural forests it is necessary to be guided by the modern concepts of synecology and model reconstructions of forest cover in pre-anthropogenic period that are briefly discussed in the paper. Based on the analysis of literature and research experience the author proposes the concept of natural forest restoration that can be applied primarily to the coniferous-broadleaf and broadleaf forests. The main goal is to create multiple-aged and polydominant near-natural forest ecosystems with higher resistance to fungal diseases and outbreaks of phytophagous insects. The field of concept application is specially protected natural areas (national parks, natural parks, wildlife sanctuaries, etc., different categories of protective forests located within the zones of coniferous-broadleaf and broadleaf forests on the East European Plain. The formation of multiple-aged forests is possible when group felling and group-clear felling that largely imitate the natural gap-mosaic stand are implemented. The formation of new generations of trees is possible both due to the natural regeneration and the development of forest cultures. The article provides the full set

  13. Klugheit. Grundbegriff des Praktischen bei Aristoteles [Prudence.The Basic Concept of the Practical in Aristotle

    Berthold Wald

    2016-12-01

    Full Text Available The article begins by recalling the most important understandings associated with the term prudence in the history of philosophy.Then it introduces the Aristotelian concept of prudence linked to practical truth—prudence seen in contrast to wisdom and knowledge of manufacturing. The article discusses various forms of rational knowledge associated with the right will, and proves the need of linking prudence to all the other ethical virtues based on moral principles. It emphasizes the problem of how to relate general principles to specific actions which involve particular goods. For resolving this problem, the article refers to Aristotle who sees the solution in political ethics which has a significant impact on individual behavior; consequently, good law and proper education are considered to be necessary conditions which allow to form the moral judgment skills for providing a morally good life. The article concludes with the claim that the proper field to capture the specificity of prudence includes the theory of human action and that of human morality.

  14. On the Meaning of Feedback Parameter, Transient Climate Response, and the Greenhouse Effect: Basic Considerations and the Discussion of Uncertainties

    Kramm, Gerhard

    2010-07-01

    In this paper we discuss the meaning of feedback parameter, greenhouse effect and transient climate response usually related to the globally averaged energy balance model of Schneider and Mass. After scrutinizing this model and the corresponding planetary radiation balance we state that (a) the this globally averaged energy balance model is flawed by unsuitable physical considerations, (b) the planetary radiation balance for an Earth in the absence of an atmosphere is fraught by the inappropriate assumption of a uniform surface temperature, the so-called radiative equilibrium temperature of about 255 K, and (c) the effect of the radiative anthropogenic forcing, considered as a perturbation to the natural system, is much smaller than the uncertainty involved in the solution of the model of Schneider and Mass. This uncertainty is mainly related to the empirical constants suggested by various authors and used for predicting the emission of infrared radiation by the Earth's skin. Furthermore, after inserting the absorption of solar radiation by atmospheric constituents and the exchange of sensible and latent heat between the Earth and the atmosphere into the model of Schneider and Mass the surface temperatures become appreciably lesser than the radiative equilibrium temperature. Moreover, neither the model of Schneider and Mass nor the Dines-type two-layer energy balance model for the Earth-atmosphere system, both contain the planetary radiation balance for an Earth in the absence of an atmosphere as an asymptotic solution, do not provide evidence for the existence of the so-called atmospheric greenhouse effect if realistic empirical data are used.

  20. What Lies behind the Concept of Customer Relationship Management? Discussing the Essence of CRM through a Phenomenological Approach

    Cristiane Drebes Pedron

    2009-01-01

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

  2. Opportunities to Learn in School and at Home: How can they predict students' understanding of basic science concepts and principles?

    Wang, Su; Liu, Xiufeng; Zhao, Yandong

    2012-09-01

    As the breadth and depth of economic reforms increase in China, growing attention is being paid to equalities in opportunities to learn science by students of various backgrounds. In early 2009, the Chinese Ministry of Education and Ministry of Science and Technology jointly sponsored a national survey of urban eighth-grade students' science literacy along with their family and school backgrounds. The present study focused on students' understanding of basic science concepts and principles (BSCP), a subset of science literacy. The sample analyzed included 3,031 students from 109 randomly selected classes/schools. Correlation analysis, one-way analysis of variance, and two-level linear regression were conducted. The results showed that having a refrigerator, internet, more books, parents purchasing books and magazines related to school work, higher father's education level, and parents' higher expectation of the education level of their child significantly predicted higher BSCP scores; having siblings at home, owning an apartment, and frequently contacting teachers about the child significantly predicted lower BSCP scores. At the school level, the results showed that being in the first-tier or key schools, having school libraries, science popularization galleries, computer labs, adequate equipment for teaching, special budget for teacher training, special budget for science equipment, and mutual trust between teachers and students significantly predicated higher BSCP scores; and having science and technology rooms, offering science and technology interest clubs, special budget for science curriculum development, and special budget for science social practice activities significantly predicted lower BSCP scores. The implications of the above findings are discussed.

  4. Twenty years of Internet-based research at SCiP: A discussion of surviving concepts and new methodologies.

    Wolfe, Christopher R

    2017-10-01

    This discussion of the symposium 20 Years of Internet-Based Research at SCiP: Surviving Concepts, New Methodologies compares the issues faced by the pioneering Internet-based psychology researchers who presented at the first symposia on the topic, at the 1996 annual meeting of the Society for Computers in Psychology, to the issues facing researchers today. New methodologies unavailable in the early days of Web-based psychological research are discussed, with an emphasis on mobile computing with smartphones that is capitalizing on capabilities such as touch screens and gyro sensors. A persistent issue spanning the decades has been the challenge of conducting scientific research with consumer-grade electronics. In the 1996 symposia on Internet-based research, four advantages were identified: easy access to a geographically unlimited subject population, including subjects from very specific and previously inaccessible target populations; bringing the experiment to the subject; high statistical power through large sample size; and reduced cost. In retrospect, it appears that Internet-based research has largely lived up to this early promise-with the possible exception of sample size, since the public demand for controlled psychology experiments has not always been greater than the supply offered by researchers. There are many reasons for optimism about the future of Internet-based research. However, unless courses and textbooks on psychological research methods begin to give Web-based research the attention it deserves, the future of Internet-based psychological research will remain in doubt.

  12. SPECIALIZED MAPPING OF CRUSTAL FAULT ZONES. PART 1: BASIC THEORETICAL CONCEPTS AND PRINCIPLES

    K. Zh. Seminsky

    2014-01-01

    Full Text Available Long-term studies of shear zones have included collection of data on fractures showing no indication of displacement which are termed as 'blank' fractures. A method aimed at mapping fault structures and stress fields has been developed on the basis of results of paragenetic analysis of measurements of abundant fractures. The method is termed as 'specialized mapping', firstly, due to its specific structural goal so that to distinguish it from the conventional geological mapping of regions in nature, and, secondly, because of the specific procedure applied to refer to fractures as references to decipher fault-block patterns of natural regions. In Part 1, basic theoretical concepts and principles of specialized mapping are described. Part 2 is being prepared for publication in one of the next issues of the journal; it will cover stages of the proposed method and describe some of the cases of its application.In terms of general organizational principles, specialized mapping is similar to other methods based on structural paragenetic analysis and differs from such methods in types of paragenesises viewed as references to reveal crustal fault zones. Such paragenesises result from stage-by-stage faulting (Fig 2 and Fig. 7 during which stress fields of the 2nd order are regularly changeable within the shear zone. According to combined experimental and natural data, a complete paragenesis of fractures in the shear zone includes a major (1st order fault plane and fractures of other seven types, R, R’, n, n’, t, t’ and T (2nd order (Fig. 4 and Fig 8. At the fracture level, each of them corresponds to a paragenesis including three nearly perpendicular systems of early ruptures (Fig. 1, which are based on two classical patterns of conjugated fractures, one of which is consistent with the position of the fault plane (Fig. 3. Taking into account that strike-slip, reverse and normal faults are similar in terms of mechanics (i.e. they are formed due to

  13. Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models: COST Action ES0905 Final Report

    Jun–Ichi Yano

    2014-12-01

    Full Text Available The research network “Basic Concepts for Convection Parameterization in Weather Forecast and Climate Models” was organized with European funding (COST Action ES0905 for the period of 2010–2014. Its extensive brainstorming suggests how the subgrid-scale parameterization problem in atmospheric modeling, especially for convection, can be examined and developed from the point of view of a robust theoretical basis. Our main cautions are current emphasis on massive observational data analyses and process studies. The closure and the entrainment–detrainment problems are identified as the two highest priorities for convection parameterization under the mass–flux formulation. The need for a drastic change of the current European research culture as concerns policies and funding in order not to further deplete the visions of the European researchers focusing on those basic issues is emphasized.

  17. Basics concepts and clinical applications of oxygen-enhanced MR imaging

    Ohno, Yoshiharu; Hatabu, Hiroto

    2007-01-01

    Oxygen-enhanced MR imaging is a new technique, and its physiological significance has not yet been fully elucidated. This review article covers (1) the theory of oxygen enhancement and its relationship with respiratory physiology; (2) design for oxygen-enhanced MR imaging sequencing; (3) a basic study of oxygen-enhanced MR imaging in animal models and humans; (4) a clinical study of oxygen-enhanced MR imaging; and (5) a comparison of advantages and disadvantages of this technique with those of hyperpolarized noble gas MR ventilation imaging. Oxygen-enhanced MR imaging provides not only the ventilation-related, but also respiration-related information. Oxygen-enhanced MR imaging has the potential to replace nuclear medicine studies for the identification of regional pulmonary function, and many investigators are now attempting to adapt this technique for routine clinical studies. We believe that further basic studies as well as clinical applications of this new technique will define the real significance of oxygen-enhanced MR imaging for the future of pulmonary functional imaging and its usefulness for diagnostic radiology and pulmonary medicine

  19. Plasma in dentistry: a review of basic concepts and applications in dentistry.

    Kim, Jae-Hoon; Lee, Mi-Ae; Han, Geum-Jun; Cho, Byeong-Hoon

    2014-01-01

    Plasma-related technologies are essential in modern industries. Recently, plasma has attracted increased attention in the biomedical field. This paper provides a basic knowledge of plasma and a narrative review of plasma applications in dentistry. To review plasma applications in dentistry, an electronic search in PubMed, SCOPUS and Google scholar up to December 2012 was done. This was followed by extensive hand searching using reference lists from relevant articles. There have been attempts to apply plasma technology in various fields of dentistry including surface modifications of dental implants, adhesion, caries treatment, endodontic treatment and tooth bleaching. Although many studies were in early stages, the potential value of plasma for dental applications has been demonstrated. To enlarge the scope of plasma applications and put relevant research to practical use, interdisciplinary research with participation of dental professionals is required.

  20. Lens ion transport: from basic concepts to regulation of Na,K-ATPase activity

    Delamere, Nicholas A.; Tamiya, Shigeo

    2009-01-01

    In the late 1960s, studies by George Duncan explained many of the basic principles that underlie lens ion homeostasis. The experiments pointed to a permeability barrier close to the surface of the lens and illustrated the requirement for continuous Na,K-ATPase-mediated active sodium extrusion. Without active sodium extrusion, lens sodium and calcium content increases resulting in lens swelling and deterioration of transparency. Later, Duncan's laboratory discovered functional muscarinic and purinergic receptors at the surface of the lens. Recent studies using intact lens suggest purinergic receptors might be involved in short-term regulation of Na,K-ATPase in the epithelium. Purinergic receptor agonists ATP and UTP selectively activate certain Src family tyrosine kinases and stimulate Na,K-ATPase activity. This might represent part of a control mechanism capable of adjusting, perhaps fine tuning, lens ion transport machinery. PMID:18614168

    2017-10-01

    The principles of Good Laboratory Practices (GLPs) are mainly intended for the laboratories performing studies for regulatory compliances. However, today GLP can be applied to broad disciplines of science to cater to the needs of the experimental objectives, generation of quality data and assay reproducibility. Considering its significance, it can now be applied in academics; industries as well as government set ups throughout the world. GLP is the best way to promote the reliability, reproducibility of the test data and hence facilitates the international acceptability. Now it is high time to translate and implement the concept of GLP beyond regulatory studies. Thus, it can pave the way for better understanding of scientific problems and help to maintain a good human and environmental health. Through this review, we have made an attempt to explore the uses of GLP principles in different fields of science and its acceptability as well as looking for its future perspectives.

  4. Basic concepts about application of dual vibration absorbers to seismic design of nuclear piping systems

    Hara, F.; Seto, K.

    1987-01-01

    The design value of damping for nuclear piping systems is a vital parameter in ensuring safety in nuclear plants during large earthquakes. Many experiments and on-site tests have been undertaken in nuclear-industry developed countries to determine rational design values. However damping value in nuclear piping systems is so strongly influenced by many piping parameters that it shows a tremendous dispersion in its experimental values. A new trend has recently appeared in designing nuclear pipings, where they attempt to use a device to absorb vibration energy induced by seismic excitation. A typical device is an energy absorbing device, made of a special material having a high capacity of plasticity, which is installed between the piping and the support. This paper deals with the basic study of application of dual vibration absorbers to nuclear piping systems to accomplish high damping value and reduce consequently seismic response at resonance frequencies of a piping system, showing their effectiveness from not only numerical calculation but also experimental evaluation of the vibration responses in a 3D model piping system equipped with dual two vibration absorbers

  5. Using Hollywood Movies to Teach Basic Geological Concepts: A Comparison of Student Outcomes

    Crowder, M. E.

    2008-12-01

    Throughout the history of cinema, events based in Earth Science have been the focus of many an action- disaster plot. From the most recent 2008 remake of Journey to the Center of the Earth, to 1965's Crack in the World, and all the way back to the 1925 silent film rendition of The Lost World, Hollywood's obsession with the geological sciences has been clear. These particular sub-genres of disaster films and science fiction present science that, from a Hollywood viewpoint, looks exciting and seems realistic. However, from a scientific viewpoint, the presentations of science are often shockingly incorrect and unfortunately serve to perpetuate common misconceptions. In 2003, Western Kentucky University began offering an elective non-majors science course, Geology and Cinema, to combat these misconceptions while using the framework of Hollywood films as a tool to appeal and connect to a broad student population. To see if this method is truly working, this study performs a student outcome comparison for basic geologic knowledge and general course perception between several sections of standard, lecture-based Introductory Geology courses and concurrent semester sections of Geology and Cinema. Preliminary results indicate that while performance data is similar between the courses, students have a more positive perception of the Cinema sections.

    Full Text Available The purpose of the paper is to examine the essence of the term «tax security», its fundamental characteristics, such as threats, risks, interests and protection, defined how the state could provide them. The paper analyses economic, social and legal nature of the term. Key indicators of tax security of Ukraine identified and analyzed. In addition, the paper studies an integrated approach of tax security threats. In case of a big amount of threats, they divided to four main sources of threats: the state of the national economy, the state of the public finances, social features of the society and institutional environment. For each source, there have been identified and analyzed the most important factors of threats of tax security of Ukraine. Methodology. The survey based on an analysis of existing studies of Ukrainian and foreign scientists about the essence and nature of "tax security" for the last 10 years. In addition, to determine the essence and the concept, goals and objectives, methods and principles of the economic nature of the tax security, main risks, threats, expectations and results of efficient tax security identified. To build an integrated approach it is necessary to analyse all existing and potential factors of threats.

Results of the survey showed that tax security is such a condition of tax security, when the process of harmonization of taxation provided under effective management of risks and threats that arise in tax area, by taking the necessary measures by the executive bodies to meet the interests of the state, society and taxpayers (business entities, organizations, people. Integrated approach of threats analysis of tax security shows that the most dangerous threats are those that are associated with poor economic development, considerable socio-economic stratification of

  9. Current and emerging basic science concepts in bone biology: implications in craniofacial surgery.

    Oppenheimer, Adam J; Mesa, John; Buchman, Steven R

    2012-01-01

    Ongoing research in bone biology has brought cutting-edge technologies into everyday use in craniofacial surgery. Nonetheless, when osseous defects of the craniomaxillofacial skeleton are encountered, autogenous bone grafting remains the criterion standard for reconstruction. Accordingly, the core principles of bone graft physiology continue to be of paramount importance. Bone grafts, however, are not a panacea; donor site morbidity and operative risk are among the limitations of autologous bone graft harvest. Bone graft survival is impaired when irradiation, contamination, and impaired vascularity are encountered. Although the dura can induce calvarial ossification in children younger than 2 years, the repair of critical-size defects in the pediatric population may be hindered by inadequate bone graft donor volume. The novel and emerging field of bone tissue engineering holds great promise as a limitless source of autogenous bone. Three core constituents of bone tissue engineering have been established: scaffolds, signals, and cells. Blood supply is the sine qua non of these components, which are used both individually and concertedly in regenerative craniofacial surgery. The discerning craniofacial surgeon must determine the proper use for these bone graft alternatives, while understanding their concomitant risks. This article presents a review of contemporary and emerging concepts in bone biology and their implications in craniofacial surgery. Current practices, areas of controversy, and near-term future applications are emphasized.

  10. The law of offshore petroleum development: basic concepts and main issues

    Carver, J.P.

    1994-01-01

    The problems associated with the delimitation of maritime areas, such as the continental shelf, are discussed with particular reference to offshore petroleum development. Methods of delimitation which have found favour are described. The principle of equidistance in delimiting the continental shelf between neighbouring states, whether opposite or adjacent is an example. Given the complexities of delimitation, acceptance of the need for agreement and that there is no definitive answer which will meet all the relevant circumstances is proposed as a starting point. How this works out is illustrated by the still hypothetical offshore international boundaries between Scotland and England. (UK)

  11. Photochemical transformations accelerated in continuous-flow reactors: basic concepts and applications.

    Su, Yuanhai; Straathof, Natan J W; Hessel, Volker; Noël, Timothy

    2014-08-18

    Continuous-flow photochemistry is used increasingly by researchers in academia and industry to facilitate photochemical processes and their subsequent scale-up. However, without detailed knowledge concerning the engineering aspects of photochemistry, it can be quite challenging to develop a suitable photochemical microreactor for a given reaction. In this review, we provide an up-to-date overview of both technological and chemical aspects associated with photochemical processes in microreactors. Important design considerations, such as light sources, material selection, and solvent constraints are discussed. In addition, a detailed description of photon and mass-transfer phenomena in microreactors is made and fundamental principles are deduced for making a judicious choice for a suitable photomicroreactor. The advantages of microreactor technology for photochemistry are described for UV and visible-light driven photochemical processes and are compared with their batch counterparts. In addition, different scale-up strategies and limitations of continuous-flow microreactors are discussed. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  12. Basic concepts for designing renewable electricity support aiming at a full-scale transition by 2050

    Verbruggen, Aviel; Lauber, Volkmar

    2009-01-01

    Renewable electricity supply is a crucial factor in the realization of a low-carbon energy economy. The understanding is growing that a full turn-over of the electricity sectors by 2050 is an elementary condition for avoiding global average temperature increase beyond 2 C. This article adopts such full transition as Europe's target when designing renewable energy policy. An immediate corollary is that phasing-in unprecedented energy efficiency and renewable generation must be paralleled by phasing-out non-sustainable fossil fuel and nuclear power technologies. The double phasing programme assigns novel meaning to nearby target settings for renewable power as share of total power consumption. It requires organizing in the medium term EU-wide markets for green power, a highly demanding task in the present context of poorly functional markets in brown power. The EU Commission's 2007/2008 proposals of expanding tradable certificates markets were not based on solid analysis of past experiences and future necessities. The keystone of sound policies on renewable electricity development is a detailed scientific differentiation and qualification of renewable electricity sources and technologies, for measuring the huge diversity in the field. We provide but structuring concepts about such qualification, because implementation requires extensive research resources. Support for renewable electricity development is organized via feed-in prices or premiums, and via quota obligations connected to tradable green certificates. Green certificates are dependent on physical generated renewable power, but separable and no joint products. Contrary to conventional wisdom we argue their separation in cost analysis but firm linking during trade. A few graphs illustrate the importance of assigning qualities to different renewable power sources/technologies. Feed-in systems based on an acceptable qualification perform generally better than certificate markets imposing uniform approaches on a

  13. keV sterile neutrino dark matter from singlet scalar decays: basic concepts and subtle features

    Merle, Alexander; Totzauer, Maximilian

    2015-01-01

    We perform a detailed and illustrative study of the production of keV sterile neutrino Dark Matter (DM) by decays of singlet scalars in the early Universe. In the current study we focus on providing a clear and general overview of this production mechanism. For the first time we study all regimes possible on the level of momentum distribution functions, which we obtain by solving a system of Boltzmann equations. These quantities contain the full information about the production process, which allows us to not only track the evolution of the DM generation but to also take into account all bounds related to the spectrum, such as constraints from structure formation or from avoiding too much dark radiation. In particular we show that this simple production mechanism can, depending on the regime, lead to strongly non-thermal DM spectra which may even feature more than one peak in the momentum distribution. These cases could have particularly interesting consequences for cosmological structure formation, as their analysis requires more refined tools than the simplistic estimate using the free-streaming horizon. Here we present the mechanism including all concepts and subtleties involved, for now using the assumption that the effective number of relativistic degrees of freedom is constant during DM production, which is applicable in a significant fraction of the parameter space. This allows us to derive analytical results to back up our detailed numerical computations, thus leading to the most comprehensive picture of keV sterile neutrino DM production by singlet scalar decays that exists up to now

  14. Coal conversion and the HTR - basic elements of novel power supply concepts

    Buerger, F.H.

    1985-01-01

    A meeting under this title was held in Dortmund on 16 to 19 September, 1985, jointly by the VGB Technische Vereinigung der Grosskraftwerksbetreiber e.V., Essen, and the Vereinigte Elektrizitaetswerke Westfalen AG (VEW), Dortmund. The meeting was held in two sections: 'Gersteinwerk power plant - the combination unit K and the KUV coal conversion system' and '7th International conference on HTR technology'. Three technologies were discussed that will have a significant role on the future energy market, i.e., the HTR reactor line (first applied in the Hamm-Uentrop THTR reactor), the new generation of coal-fired power plants with combined gas/steam turbines, and the coal gasification technology. All three systems will make more efficient and less-polluting use of domestic coal by using HTR process heat, by converting coal to widen its range of applications, and by providing more efficient combination units for power plants.

  15. Product, not process! Explaining a basic concept in agricultural biotechnologies and food safety.

    Tagliabue, Giovanni

    2017-12-01

    Most life scientists have relentlessly recommended any evaluative approach of agri-food products to be based on examination of the phenotype, i.e. the actual characteristics of the food, feed and fiber varieties: the effects of any new cultivar (or micro-organism, animal) on our health are not dependent on the process(es), the techniques used to obtain it.The so-called "genetically modified organisms" ("GMOs"), on the other hand, are commonly framed as a group with special properties - most frequently seen as dubious, or even harmful.Some social scientists still believe that considering the process is a correct background for science-based understanding and regulation. To show that such an approach is utterly wrong, and to invite scientists, teachers and science communicators to explain this mistake to students, policy-makers and the public at large, we imagined a dialogue between a social scientist, who has a positive opinion about a certain weight that a process-based orientation should have in the risk assessment, and a few experts who offer plenty of arguments against that view. The discussion focuses on new food safety.

    Park, Ji Eun [Dept. of Radiology and Research Institute of Radiology, University of Ulsan College of Medicine, Asan Medical Center, Seoul (Korea, Republic of); Jahng, Geon Ho [Dept. of Radiology, Kyung Hee University Hospital at Gangdong, College of Medicine, Kyung Hee University, Seoul (Korea, Republic of); Jeong, Ha Kyu [Philips Korea, Seoul (Korea, Republic of)

    2016-12-15

    Amide proton transfer (APT) imaging is gaining attention as a relatively new in vivo molecular imaging technique that has higher sensitivity and spatial resolution than magnetic resonance spectroscopy imaging. APT imaging is a subset of the chemical exchange saturation transfer mechanism, which can offer unique image contrast by selectively saturating protons in target molecules that get exchanged with protons in bulk water. In this review, we describe the basic concepts of APT imaging, particularly with regard to the benefit in clinics from the current literature. Clinical applications of APT imaging are described from two perspectives: in the diagnosis and monitoring of the treatment response in brain glioma by reflecting endogenous mobile proteins and peptides, and in the potential for stroke imaging with respect to tissue acidity.

  18. Basic concepts in metal work failure after metastatic spine tumour surgery.

    Kumar, Naresh; Patel, Ravish; Wadhwa, Anshuja Charvi; Kumar, Aravind; Milavec, Helena Maria; Sonawane, Dhiraj; Singh, Gurpal; Benneker, Lorin Michael

    The development of spinal implants marks a watershed in the evolution of metastatic spine tumour surgery (MSTS), which has evolved from standalone decompressive laminectomy to instrumented stabilization and decompression with reconstruction when necessary. Fusion may not be feasible after MSTS due to poor quality of graft host bed along with adjunct chemotherapy and/or radiotherapy postoperatively. With an increase in the survival of patients with spinal tumours, there is a probability of an increase in the rate of implant failure. This review aims to help establish a clear understanding of implants/constructs used in MSTS and to highlight the fundamental biomechanics of implant/construct failures. Published literature on implant failure after spine surgery and MSTS has been reviewed. The evolution of spinal implants and their role in MSTS has been briefly described. The review defines implant/construct failures using radiological parameters that are practical, feasible, and derived from historical descriptions. We have discussed common modes of implant/construct failure after MSTS to allow further understanding, interception, and prevention of catastrophic failure. Implant failure rates in MSTS are in the range of 2-8%. Variability in patterns of failure has been observed based on anatomical region and the type of constructs used. Patients with construct/implant failures may or may not be symptomatic and present either as early (failures (> 3months). It has been noted that not all the implant failures after MSTS result in revisions. Based on the observed radiological criteria and clinical presentations, we have proposed a clinico-radiological classification for implant/construct failure after MSTS.

  19. Triatominae biochemistry goes to school: evaluation of a novel tool for teaching basic biochemical concepts of Chagas disease vectors.

    Cunha, Leonardo Rodrigues; Cudischevitch, Cecília de Oliveira; Carneiro, Alan Brito; Macedo, Gustavo Bartholomeu; Lannes, Denise; Silva-Neto, Mário Alberto Cardoso da

    2014-01-01

    We evaluate a new approach to teaching the basic biochemistry mechanisms that regulate the biology of Triatominae, major vectors of Trypanosoma cruzi, the causative agent of Chagas disease. We have designed and used a comic book, "Carlos Chagas: 100 years after a hero's discovery" containing scientific information obtained by seven distinguished contemporary Brazilian researchers working with Triatominaes. Students (22) in the seventh grade of a public elementary school received the comic book. The study was then followed up by the use of Concept Maps elaborated by the students. Six Concept Maps elaborated by the students before the introduction of the comic book received an average score of 7. Scores rose to an average of 45 after the introduction of the comic book. This result suggests that a more attractive content can greatly improve the knowledge and conceptual understanding among students not previously exposed to insect biochemistry. In conclusion, this study illustrates an alternative to current strategies of teaching about the transmission of neglected diseases. It also promotes the diffusion of the scientific knowledge produced by Brazilian researchers that may stimulate students to choose a scientific career. © 2014 The International Union of Biochemistry and Molecular Biology.

  3. Critical groups - basic concepts

    Carter, M.W.

    1992-01-01

    The potential exposure pathways from the land application site to man are presented. It is emphasised that the critical group is not necessary the population group closest to the source. It could be the group impact by the most significant pathways(s). Only by assessing the importance of each of these pathways and then combining them can a proper choice of critical group be made. It would be wrong to select a critical group on the basis that it seems the most probable one, before the pathways have been properly assessed. A calculation in Carter (1983) suggested that for the operating mine site, the annual doses to an Aboriginal person, a service worker and a local housewife, were all about the same and were in the range 0.1 to 0.2 mSv per year. Thus it may be that for the land application area, the critical group turns out to be non-Aboriginal rather than the expected Aboriginal group. 6 refs., 3 figs

  4. Some basic business concepts

    Jones, D.R.

    1992-01-01

    This paper reports that recent history has shown that, even for industries in state-owned, centrally planned economies, the measurement of success must relate to making an economic profit or else the industry, and ultimately the entire economy, will fail spectacularly. In short, success must be measured by the KISS (keep it simple, stupid) principle that income must exceed outgo. Let's expand the KISS principle to a definition of success (profit or loss) for an enterprise of any size engaged in oil and gas exploration and development (including acquisition of producing properties): Profit = Income + Drawdown of cash reserves - Outgo. Note that this is not an accounting definition nor a tax definition nor even a business school definition. It is a survival definition. If this measure is negative at any time, the enterprise can continue to exist only at the forbearance of its creditors

    1983-01-01

    According to the Atomic Act, article 9a, paragraph 1, the licensees of nuclear power plants in the Federal Republic of Germany are obliged to provide for the management of radioactive wastes resulting from the operation of these plants. Concerning the provisions to be made for the management of such wastes, two concepts are discussed: nuclear reprocessing and final waste disposal center (Nukleares Entsorgungszentrum, NEZ); and the integrated spent fuel and waste management concept (Integriertes Entsorgungskonzept, IEK). Unlike the NEZ, the IEK-concept may have different sites for the following fuel cycle facilities: intermediate spent fuel storage, reprocessing, waste conditioning and final disposal, and uranium and plutonium fuel element fabrication facilities. The fundamental differences of the pertinent transports are presented. Transport scenarios expected under the two alternatives NEZ and IEK have been elaborated for the purpose of a data collection covering the following aspects: materials to be shipped, number of packages shipped, number of packages shipped per transport, transport by rail or by road, transport routes and distances, and duration of transports

  9. Responsibility: The First Virtue of Innovation? A discussion of some ethical and meta-ethical issues concerning the concept of ‘responsibility’ in technological innovation

    Espen D. Stabell

    2014-11-01

    Full Text Available In this paper I investigate the concept of responsibility in the context of technological innovation, with reference to two types of responsibility: ex post and ex ante responsibility. Exposing the shortcomings of ex post responsibility in the context of innovation, I examine different ways of conceiving of a form of ex ante responsibility suitable for our current technological situation. Here I identify two positions with very different approaches to the question of the ethical status of responsibility: Hans Jonas’s concept of responsibility as an ethical principle structuring moral behavior, and René von Schomberg’s idea of responsibility as “responsiveness” linked to procedures of communication and collaboration. Rejecting von Schomberg’s concept on ethico-philosophical grounds, I argue in favor of a critical rehabilitation of some basic thoughts in the philosophy of Jonas. Finally, I suggest taking the step from the Jonasian ethics of responsibility towards the Hegelian concept of Sittlichkeit – a concrete social morality that disentangles responsibility from the dilemmas of subjectivist morality.

  12. Emerging models for facilitating contact between people genetically related through donor conception: a preliminary analysis and discussion

    Marilyn Crawshaw

    2015-12-01

    Full Text Available Previous research indicates interest among some donor-conceived people, donors and recipient parents in having contact. Outcomes of such contact appear largely, but not universally, positive. This paper seeks to understand better the characteristics of associated support services. Information gathered using the authors' direct experiences and professional and personal networks in different parts of the world indicates the emergence of four main groupings: (i publically funded services outside of treatment centers; (ii services provided by fertility treatment or gamete bank services; (iii services provided privately by independent psychosocial or legal practitioners; and (4 services organized by offspring and/or recipient parents. Key operational features examined were: (i who can access such services and when; (ii what professional standards and funding are in place to provide them; and (iii how ‘matching’ and contact processes are managed. Differences appear influenced variously by the needs of those directly affected, local policies, national legislation and the interests of the fertility services which recruit gamete donors and/or deliver donor conception treatments. The paper is intended to inform fuller debate about how best to meet the needs of those seeking information and contact, the implications for the way that fertility treatment and gametes donation services are currently provided and future research needs.

  14. Basic concepts on threat, vulnerability and risk associated to a process of massive use of gaseous fuels

    Ospina G, J.A.

    1998-01-01

    The massive use of gaseous fuels, natural gas and liquefied gas of the oil or G.L.P., demands the implementation and complex technologies utilization in each one of the technical activities operative that transportation, distribution and consumption of these fuels requires, in order to accomplish each one of they in the form most efficient and possible insurance. Natural phenomena (earthquakes, landslides) and technical phenomena and caused by the man (terrorism, not appropriate designs of transportation and distribution net, wrong manipulation of the gas equipment) represent a latent danger for the distributors as well as for the users of the gas, generating a threat, of large proportions, for the normal development of the program of massive use of the gas, in any geographical environment where this is implemented. In this article are described the disaster concepts, threat, vulnerability and risk and the form as are related to the project of massive use of the gas, basically to transportation areas, distribution and final use

    The ultimate goal of vaccine development is licensure of a safe and efficacious product that has a well-defined manufacturing process resulting in a high quality product. In general, clinical development and regulatory approval occurs in a linear, sequential manner: Phase 1 - safety, immunogenicity; Phase 2 - immunogenicity, safety, dose ranging and preliminary efficacy; Phase 3 - definitive efficacy, safety, lot consistency; and, following regulatory approval, Phase 4 - post-marketing safety and effectiveness. For candidate TB vaccines, where correlates of protection are not yet identified, phase 2 and 3 efficacy of disease prevention trials are, by necessity, very large. Each trial would span 2-5 years, with full licensure expected only after 1 or even 2 decades of development. Given the urgent unmet need for a new TB vaccine, a satellite discussion was held at the International African Vaccinology Conference in Cape Town, South Africa in November 2012, to explore the possibility of expediting licensure by use of an "adaptive licensure" process, based on a risk/benefit assessment that is specific to regional needs informed by epidemiology. This may be appropriate for diseases such as TB, where high rates of morbidity, mortality, particularly in high disease burden countries, impose an urgent need for disease prevention. The discussion focused on two contexts: licensure within the South African regulatory environment - a high burden country where TB vaccine efficacy trials are on-going, and licensure by the United States FDA --a well-resourced regulatory agency where approval could facilitate global licensure of a novel TB vaccine.

    2006-08-01

    Full Text Available This work describes the modeling of a hypermedia learning system (called “Biomec” that integrates physical, biomechanical and anatomical concepts involved in the human motion and a study carried out with undergraduate students who interacted with the system. The instructional design of the “Biomec” hypermedia system was developed on the basis of a theoretical framework which articulates the Cognitive Flexibility Theory and the interdisciplinary approach to knowledge. The system was evaluated based on its use by students of Biomechanics I and Kinesiology in a Pre Service Teachers Training Course of Physical Education aiming to discuss the following questions: (i what is its impact on the students’ attitude related to Physics? (ii in what extent does the hypertextual approach to the content favor the interdisciplinary conception of human motion? (iii in what extent do the students’ navigation profiles adapt to conceptual needs of the different disciplines of the course? The students answered instruments that assessed affective and cognitive aspects before and after the interaction with the system, and had their navigation registered and analyzed. The set of data obtained allowed to conclude that the “Biomec” system is a relevant instructional material, capable of positively influence the students’ attitude related to Physics, to favor the interdisciplinary approach of human motion and to attend the students enrolled in Biomechanics I better than the students enrolled in Kinesiology.

  17. Aquecimento em forno de microondas / desenvolvimento de alguns conceitos fundamentais Heating in microwave ovens/ developing of basic concepts

    Ana Claudia R. N. Barboza

    2001-12-01

    Full Text Available The microwave oven became a common domestic equipment, due mainly to the short time spent to heat foods. One of the most interesting characteristics of the microwave oven is the selective heating. Different from the conventional oven, where the heating is not selective, the heating by microwave depends on the chemical nature of the matter. Many Students of Chemistry have no knowledge of the principles involved in this selective heating, in spite of the daily microwave oven use. The heating by microwave is feasible for chemistry courses. In discussions about the microwave absorption by the matter it is possible to explore chemical properties like: heat capacity, chemical bound, molecular structure, dipole moments, polarization and dielectric constant. This paper presents the basic principles involved in the microwave heating. It is proposed a simple and inexpensive experiment that could be developed in general chemistry courses, to illustrate the relationship between heating and the chemical properties of some solvents. Experiments to check the power of the microwave oven are also proposed.

  18. A Modern Twist on the Beaumont and St. Martin Case: Encouraging Analysis and Discussion in the Bioethics Classroom with Reflective Writing and Concept Mapping

    Carlos C. Goller

    2014-09-01

    Full Text Available Historical ethical dilemmas are a valuable tool in bioethics courses. However, garnering student interest in reading and discussing the assigned cases in the classroom can be challenging. In an effort to actively engage undergraduate and graduate students in an Ethical Issues in Biotechnology course, an activity was developed to encourage reflection on a classical ethical dilemma between a patient, St. Martin, and his employer/caretaker, Beaumont. Two different texts were used to analyze the ethical ramifications of this relationship: a chapter in a popular press book and a short perspective in a medical journal. Participants read the book chapter for homework and discussed it in class. This easy read highlights the fundamental ethical issues in the relationship between two men. Students were then provided with a second text focusing on the scientific accomplishments achieved through Beaumont's experimentation on St. Martin. A structured worksheet prompted participants to reflect on their feelings after reading each text and create a concept map depicting the dilemma. Student-generated concept maps and written reflections indicate participants were able to list the ethical issues, analyze the situation, and evaluate the information provided. This activity not only encouraged higher-level thinking and reflection, it also mirrored the course's structured approach of using concept mapping and reflection to dissect ethical dilemmas.

  19. Mitochondrial encephalopathy, lactic acidosis, and strokelike episodes: basic concepts, clinical phenotype, and therapeutic management of MELAS syndrome.

    Sproule, Douglas M; Kaufmann, Petra

    2008-10-01

    Since the initial description almost 25 years ago, the syndrome of mitochondrial encephalopathy, lactic acidosis, and strokelike episodes (MELAS) has been a useful model to study the complex interplay of factors that define mitochondrial disease. This syndrome, most commonly caused by an A-to-G transition mutation at position 3243 of the mitochondrial genome, is typified by characteristic neurological manifestations including seizures, encephalopathy, and strokelike episodes, as well as other frequent secondary manifestations including short stature, cognitive impairment, migraines, depression, cardiomyopathy, cardiac conduction defects, and diabetes mellitus. In this review, we discuss the history, pathogenesis, clinical features, and diagnostic and management strategies of mitochondrial disease in general and of MELAS in particular. We explore features of mitochondrial genetics, including the concepts of heteroplasmy, mitotic segregation, and threshold effect, as a basis for understanding the variability and complicated inheritance patterns seen with this group of diseases. We also describe systemic manifestations of MELAS-associated mutations, including cardiac, renal, endocrine, gastrointestinal, and endothelial abnormalities and pathology, as well as the hypothetical role of derangements to COX enzymatic function in driving the unique pathology and clinical manifestations of MELAS. Although therapeutic options for MELAS and other mitochondrial diseases remain limited, and recent trials have been disappointing, we also consider current and potential therapeutic modalities.

  20. Impact of a didactic sequence on basic Astronomy concepts for graduates in physics of online and classroom modalities

    Voelzke, M. R.; Barbosa, J. I. L.

    2017-07-01

    In the transition from elementary school to high school, the topics related to astronomy are studied within the curriculae component of physics. In this context, at some point of time a Physic's teacher at this level of education will be faced with the need to work with the contents related to this science. In this way, it is important to broaden the discussion about teacher education, as well as to apply in practice the means for it. Therefore, this work has the objective to present the results, obtained by application of a questionnaire at the beginning (a pre-test), and at the final stage by a course for physics graduates of online and classroom modalities (completed with a post-test), which was organized through the Potentially Significant Teaching Units - PSTUs; and this work also presents the level of satisfaction of them in relation to the course. It is an applied and descriptive research, and the adopted technical procedures consisted of the survey and a participatory research. The data were organized in spreadsheets and the statistical analyzes were made in the sequence, with the objective of establishing comparisons between the studied groups, of their evolution of acquired knowledge and their level of satisfaction, resulting from the development in the course. The results indicate that there has been an evolution of the student's s basic knowledge with relation to the proposed topics of Astronomy in the didactic sequences, i.e., the activities developed in the administered course created a favorable atmosphere for the learning, which is therefore contributing to the initial formation of these physics teachers.

  1. The baseline in bottom-up energy efficiency and saving calculations - A concept for its formalisation and a discussion of relevant options

    Reichl, Johannes; Kollmann, Andrea

    2011-01-01

    One of the central variables in bottom-up energy efficiency and saving calculations is the energy consumption baseline. In the evaluation of energy efficiency measures, developing this baseline is a challenging task, which may involve serious problems, especially if the energy service of the analysed subject has changed while the energy efficiency measure was being implemented. In this paper we present a formalised concept of the process of developing the baseline that is flexible enough to deal with various difficulties, such as changes in the levels of the energy services involved. We also discuss the most relevant options for deriving the necessary variables.

    2003-01-01

    Full Text Available A questão da adesão à terapêutica tem sido discutida e estudada por profissionais de saúde por se tratar de um ponto fundamental para a resolubilidade de um tratamento. Neste artigo são discutidos, a partir de estudos de adesão à terapêutica medicamentosa relatados na literatura, os significados adotados para o fenômeno da adesão e os fatores a ele relacionados. Estudos de adesão à terapêutica foram analisados quanto aos seus conceitos e pressupostos, metodologias empregadas e o papel designado para profissionais e pacientes envolvidos. São discutidos os pressupostos teóricos encontrados nos estudos, e os fatores relacionados ao tema, que envolvem questões relativas ao tratamento, ao profissional de saúde e à doença, e as metodologias adotadas nestes estudos, que são baseadas em métodos diretos e indiretos e qualitativos, alguns com abordagem fiscalizadora. Conclui-se que os estudos no campo dos medicamentos em geral não priorizam o papel do paciente no processo saúde/doença/tratamento, comprometendo a capacidade dos estudos de obter uma compreensão mais ampla e profunda sobre o tema.Research and discussion on compliance with medical regimens have been taken because compliance is an important part of a treatment. This paper discusses the meanings adopted to compliance and the factors associated to it in the current literature. Presuppositions, concepts, methodologies, target public and the doctor and patient roles approach of studies on compliance were analyzed. The factors associated with compliance referred in the literature, such as the type of treatment, illness and doctors communication; the qualitative, direct and indirect methodologies adopted, many times with inspect character, were also discussed. We conclude that studies of medications use generally do not emphasize the patient role in the health/illness/treatment process, and so, can not be as comprehensive as necessary.

  7. [August Weismann's concept of germ plasma as the basic reason for the inadequacy of neo-Darwinism].

    Grodnitskiĭ, D L

    2000-01-01

    Neo-Darwinism is a result of synthesis of Darwinian concept of natural selection with Weismannian concept of germ plasma. The concept of germ plasma is based on a hypothesis that phenotypic traits are completely determined by genes. Hence, neo-Darwinism describes evolution as a process of alternation of gene frequencies under the effect of natural selection. This is an inadequate approach to the study of evolution. In the course of evolution, genes change their functions, whereas phenotypic characters change their corresponding genes. As a result, every step of evolutionary transformation changes the structure of phenotype-to-genotype correspondence. Therefore, phenotypic evolution cannot be described in genetic terms, the same as to human languages cannot be translated one into another whenever the meaning of words is constantly changing. Consequently, Weismannian germ-plasma concept adequately describes the relation of characters to genes only during stasis, but is inapplicable to evolution.

  13. The concept and tasks of the basic method of investigation of crimes related to illegal trafficking narcotic drugs

    Chistova L.E.

    2017-04-01

    Full Text Available the article substantiates the need to develop a basic methodology for investigating crimes related to illicit trafficking in narcotic drugs due to the fact that these crimes are inextricably linked, interdependent and can not be carried out separately from each other in principle. The existing separate private methods develop recommendations for the investigation of specific types of crimes, for example, only smuggling of these funds or their sale and they are not connected with each other. In this regard, it is not possible to trace the whole cycle of criminal activity from the introduction of controlled means to illicit trafficking prior to their sale. Therefore, the basic methodology for investigating such crimes will allow us to trace the whole chain of criminal acts and to reveal all the circumstances that affect the full and objective investigation of such crimes.

  15. Astronomy: a proposal to promote meaningful learning of basic concepts of Astronomy in the shaping of teachers of High School Education

    Luiz Marcelo Darroz

    2013-04-01

    Full Text Available One presents, in this article, the process of drawing up and developing a didactic proposal about basic concepts of Astronomy. This proposal, which sought to build an educational path for the occurrence of significant learning of the concepts covered, was developed under an extension course to a group of 13 students graduating from teacher training in High School of a public school in Passo Fundo, Rio Grande do Sul. Initially one has developed the teaching methodology following from the Theory of Meaningful Learning Conceptions. The traces of meaningful learning have been obtained by means of instruments of research and evaluation, such as conceptual maps and role playing of the studied contents where the students transposed the approached subjects into new contexts. The obtained results from the learning questionnaires reached a high rate of hits. Through the registries of the meetings and the representations by drawings of the concepts, one has noticed that the students have genuinely understood the approached subjects. Through the conceptual maps the students were able to establish a progressive differentiation and an integrative reconciliation of the concepts. Thus, it was concluded that a methodology that takes into consideration what the student already knows it is essential to develop the joy of Science, the construction of meaning and appreciation of what is being learned.

    Many features from the background for an intensified application of fracture mechanics concepts in many industries world-wide. These include requirements for a permanent increase of the level of performance of technical components and structures by the introduction of new materials, joining technologies and design principles, the problem of ageing components and life extension, an increased emphasis on non-destructive in-service inspection combined with improved NDT techniques, and also a number of failure events caused by fatigue and fracture The aim of the present paper is to give a brief state-of-the-art review on how fracture mechanics is applied in different industrial branches today. This is based on standards and guidelines in the aerospace industry, in the nuclear and fossil power generation, in the chemical and petrochemical and the pipeline industry, in civil engineering, offshore technique and other fields. Based on the review an outlook is given on a future development that would be reasonable and desirable from the point of view of a basically unified philosophy of fracture mechanics application.

  5. Concept and basic performance of an in-pile experimental reactor for fast breeder reactors using fast driver core

    Obara, Toru; Sekimoto, Hiroshi

    1997-01-01

    The possibility of an in-pile experimental reactor for fast breeder reactors using a fast driver core is investigated. The driver core is composed of a particle bed with diluted fuel. The results of various basic analyses show that this reactor could perform as follows: (1) power peaking at the outer boundary of test core does not take place for large test core; (2) the radial power distribution in test fuel pin is expected to be the same as a real reactor; (3) the experiments with short half width pulse is possible; (4) for the ordinary MOX core, enough heating-up is possible for core damage experiments; (5) the positive effects after power burst can be seen directly. These are difficult for conventional thermal in-pile experimental reactors in large power excursion experiments. They are very attractive advantages in the in-pile experiments for fast breeder reactors. (author)

    Full Text Available Introduction: The basic medical sciences section requires 2.5 years in the medical education curriculum. Practical courses complement theoretical knowledge in this period to improve their appreciation. Despite spending lots of disbursement and time, this period’s efficacy is not clearly known. Methods: One hundred thirty-three General Practitioner (GP students have been included in this descriptive cross-sectional study and were asked by questionnaire about the positive impact of practical courses on learning theoretical knowledge. Data were analyzed by descriptive statistics. Result: The agreement in “Practical Head and Neck Anatomy” was 40.91% ± 29.45, in “Practical Trunk Anatomy” was 63.62% ± 2.32 and in “Practical Anatomy of Extremities” was 56.16% ± 2.57. In “Practical Histology”, agreement was 69.50%±2.19; “Practical Biophysics” was 45.97%±2.25, “Practical Physiology” 61.75%±2.17; “Practical Biochemistry” 36.28%±2.42; “Practical Pathology” 59.80%±2.53; “Practical Immunology” 56.25%±26.40; “Practical Microbiology and Virology” 60.39%±2.27 and “Practical Mycology and Parasitology” 68.2%± 2.16.Conclusion: GP students in Tabriz University of Medical Sciences are not optimistic about the applicability of practical courses of basic medical sciences lessons.

  7. Renaissance of criticism on the concept of brain death--the role of legal medicine in the context of the interdisciplinary discussion.

    2016-03-01

    In the practice of legal medicine in Germany, the assessment of brain death is of minor importance and attracts little attention. However, since several years, international criticism on the concept of brain death has culminated. By reviewing literature and the results of a questionnaire distributed among the participants of the 93rd Annual Congress of the Germany Society of Legal Medicine, the state of knowledge and the current views on brain death were evaluated. Literature search of recent publications regarding brain death was performed (PubMed database, references of legal medicine, Report of the President's Council on Bioethics, USA 2008). A questionnaire was developed and distributed among the participants of the Congress. The assumption that individual and brain death are synonymous is criticized. Internationally, there are trends to harmonize the very different clinical criteria to assess brain death. The diagnostic advantage of novel techniques such as CT angiography is controversially discussed. It becomes apparent that procedures which record the blood flow and perfusion of the brain will be applied more in the future. Regrettably, these developments are not described in the literature of legal medicine. Moreover, among German forensic scientists, different views concerning brain death exist. The majority favors its equivalent treatment with individual death. The thanatological background can be improved concerning certain aspects of brain death as well as its legal implications. Teaching and research in legal medicine should include the subject brain death. Expertise in forensic science may contribute to the interdisciplinary discussion on brain death. The transfer of actual knowledge, also on disputed ethical aspects of thanatology, to physicians of all disciplines is of great importance.

    Satria, E.

    2018-03-01

    Preservice teachers in primary education should be well equipped to meet the challenges of teaching primary science effectively in 21century. The purpose of this research was to describe the projects for the implementation of Science-Technology-Society (STS) approach in Basic Concept of Natural Science course as application of optical and electrical instruments’ material by the preservice teachers in Elementary Schools Teacher Education Program. One of the reasons is the lack of preservice teachers’ ability in making projects for application of STS approach and optical and electrical instruments’ material in Basic Concept of Natural Science course. This research applied descriptive method. The instrument of the research was the researcher himself. The data were gathered through observation and documentation. Based on the results of the research, it was figured out that preservice teachers, in groups, were creatively and successful to make the projects of optical and electrical instruments assigned such as projector and doorbell. It was suggested that the construction of the instruments should be better (fixed and strong structure) and more attractive for both instruments, and used strong light source, high quality images, and it could use speaker box for projector, power battery, and heat sink for electrical instruments.

    The coalition agreement concluded between the parties in government, i.e. SPD and Alliance 90/The Greens, after the 1998 federal elections provided for an approach to back-end fuel cycle conditions for German nuclear power plants which differed from the practice intended up to that point. Among other things, only one single repository in deep geologic formations is to be available approximately from 2030 on. Exploration of the Gorleben salt dome is to be interrupted because of prevailing doubts while, at the same time, a basic discussion is to be held about potentially suitable host rock varieties and sites. The 'Working Party of Selection Procedures for Repository Sites (AkEnd)' instituted by the federal government is to elaborate scientific siting criteria under these conditions. The authors, who are members of AkEnd, come to the conclusion, based on technical findings and the historical back-end fuel cycle and siting situation in Germany, that a multi-repository concept incorporates substantial advantages. These are the aspects referred to: - Back-end fuel cycle concept: The multi-repository concept offers clearcut advantages in the far advanced Konrad repository project. This is true also against the background of the volume of waste with negligible heat generation to be managed by public authorities. - Long-term safety: Advantages exist, among other things, with respect to technical safety regarding possible compromises in a single-repository concept and the possible restriction of the number of potential sites. - Methods of detection: Spreading the waste over two or more repositories offers benefits in the technical aspects of detection. - Cost: A differentiated assessment of the cost arising in connection with the total amount of waste to be stored in repositories indicates benefits of a multi-repository concept, especially for the public authorities.

  13. Astronomy4Kids: Utilizing online video forums to teach basic planetary concepts to children (pre-K to 2nd-grade)

    Pearson, Richard L.

    2016-10-01

    We have developed Astronomy4Kids to help cultivate the next generation of scientists by using technology to reach every interested child in both formal and informal learning environments. This online video series fills the void of effective STEM education tools for children under the age of 8. Our first collection of videos discuss many planetary topics, including the following: planet and moon formation theories, solar and lunar eclipses, and the seasonal effect of the Earth's tilt. As education and outreach become a larger focus of groups such as AAS and NASA, it is imperative to include programs such as Astronomy4Kids to extend these initiatives to younger age groups.Traditionally, this age group has been viewed as too young to be introduced to physics and astronomy concepts. However, child development research is consistently demonstrating the amazing plasticity of a young child's mind: the younger one is introduced to a complex concept, the easier it is to grasp later on. Following the philosophies of Fred Rogers, we present children with a real, relatable, instructor allowing them to focus on the concepts being presented.The format of Astronomy4Kids includes short instruction video clips that usually include a hands-on activity that is easily reproduced at home or in the classroom. This permits flexibility in how the video series is utilized. Within formal classroom or after-school situations, teachers and instructors can lead the discussion and activity with help from the video and supplemental materials (e.g. worksheets, concept outlines, etc.). Informal environments permit the viewer to complete the tasks on their own or simply enjoy the presentation. The video series can be found on YouTube (under "Astronomy 4 Kids") or Facebook (at www.facebook.com/astronomy4kids); we have also expanded to Instagram (www.instragram.com/astronomy4kids) and Pinterest (www.pinterest.com/astronomy4kids).

    2018-01-01

    Creative thinking was an important learning skill in the 21st Century via learning and innovation to promote students' creative thinking and working with others and to construct innovation. This is one of the important skills that determine the readiness of the participants to step into the complex society. The purposes of this research were 1) to compare the learning achievement of students after using basic character design and animation concepts using the flipped learning and project-based learning and 2) to make a comparison students' creative thinking between pretest and posttest. The populations were 29 students in Multimedia Technology program at Thepsatri Rajabhat University in the 2nd semester of the academic year 2016. The experimental instruments were lesson plans of basic character design and animation concepts using the flipped learning and project based learning. The data collecting instrument was creative thinking test. The data were analyzed by the arithmetic mean, standard deviation and The Wilcoxon Matched Pairs Signed-Ranks Test. The results of this research were 1) the learning achievement of students were statistically significance of .01 level and 2) the mean score of student's creativity assessment were statistically significance of .05 level. When considering all of 11 KPIs, showed that respondents' post-test mean scores higher than pre-test. And 5 KPIs were statistically significance of .05 level, consist of Originality, Fluency, Elaboration, Resistance to Premature Closure, and Intrinsic Motivation. It's were statistically significance of .042, .004, .049, .024 and .015 respectively. And 6 KPIs were non-statistically significant, include of Flexibility, Tolerance of Ambiguity, Divergent Thinking, Convergent Thinking, Risk Taking, and Extrinsic Motivation. The findings revealed that the flipped learning and project based learning provided students the freedom to simply learn on their own aptitude. When working together with project

  3. The effects of using concept mapping as an artifact to engender metacognitive thinking in first-year medical students' problem-based learning discussions: A mixed-methods investigation

    Shoop, Glenda Hostetter

    Attention in medical education is turning toward instruction that not only focuses on knowledge acquisition, but on developing the medical students' clinical problem-solving skills, and their ability to critically think through complex diseases. Metacognition is regarded as an important consideration in how we teach medical students these higher-order, critical thinking skills. This study used a mixed-methods research design to investigate if concept mapping as an artifact may engender metacognitive thinking in the medical student population. Specifically the purpose of the study is twofold: (1) to determine if concept mapping, functioning as an artifact during problem-based learning, improves learning as measured by scores on test questions; and (2) to explore if the process of concept mapping alters the problem-based learning intragroup discussion in ways that show medical students are engaged in metacognitive thinking. The results showed that students in the problem-based learning concept-mapping groups used more metacognitive thinking patterns than those in the problem-based learning discussion-only group, particularly in the monitoring component. These groups also engaged in a higher level of cognitive thinking associated with reasoning through mechanisms-of-action and breaking down complex biochemical and physiologic principals. The students disclosed in focus-group interviews that concept mapping was beneficial to help them understand how discrete pieces of information fit together in a bigger structure of knowledge. They also stated that concept mapping gave them some time to think through these concepts in a larger conceptual framework. There was no significant difference in the exam-question scores between the problem-based learning concept-mapping groups and the problem-based learning discussion-only group.

    Since it is desired to enhance availability and safety of nuclear power plants operation and maintenance by removing human factor, there are many researches and developments for intelligent operation or diagnosis using artificial intelligence (AI) technique. We have been developing an autonomous operation and maintenance system for nuclear power plants by substituting AI's and intelligent robots. It is indispensable to use various and large scale knowledge relative to plant design, operation, and maintenance, that is, whole life cycle data of the plant for the autonomous nuclear power plant. These knowledge must be given to AI system or intelligent robots adequately and opportunely. Moreover, it is necessary to insure real time operation using the large scale knowledge base for plant control and diagnosis performance. We have been studying on the large scale and real time knowledge base system for autonomous plant. In the report, we would like to present the basic concept and expecting performance of the knowledge base for autonomous plant, especially, autonomous control and diagnosis system. (author)

  6. Proof of concept of a workflow methodology for the creation of basic canine head anatomy veterinary education tool using augmented reality.

    Roxie Christ

    Full Text Available Neuroanatomy can be challenging to both teach and learn within the undergraduate veterinary medicine and surgery curriculum. Traditional techniques have been used for many years, but there has now been a progression to move towards alternative digital models and interactive 3D models to engage the learner. However, digital innovations in the curriculum have typically involved the medical curriculum rather than the veterinary curriculum. Therefore, we aimed to create a simple workflow methodology to highlight the simplicity there is in creating a mobile augmented reality application of basic canine head anatomy. Using canine CT and MRI scans and widely available software programs, we demonstrate how to create an interactive model of head anatomy. This was applied to augmented reality for a popular Android mobile device to demonstrate the user-friendly interface. Here we present the processes, challenges and resolutions for the creation of a highly accurate, data based anatomical model that could potentially be used in the veterinary curriculum. This proof of concept study provides an excellent framework for the creation of augmented reality training products for veterinary education. The lack of similar resources within this field provides the ideal platform to extend this into other areas of veterinary education and beyond.

  8. Analysis of chemical concepts as the basic of virtual laboratory development and process science skills in solubility and solubility product subject

    Syafrina, R.; Rohman, I.; Yuliani, G.

    2018-05-01

    This study aims to analyze the concept characteristics of solubility and solubility products that will serve as the basis for the development of virtual laboratory and students' science process skills. Characteristics of the analyzed concepts include concept definitions, concept attributes, and types of concepts. The concept analysis method uses concept analysis according to Herron. The results of the concept analysis show that there are twelve chemical concepts that become the prerequisite concept before studying the solubility and solubility and five core concepts that students must understand in the solubility and Solubility product. As many as 58.3% of the definitions of the concepts contained in high school textbooks support students' science process skills, the rest of the definition of the concept is memorized. Concept attributes that meet three levels of chemical representation and can be poured into a virtual laboratory have a percentage of 66.6%. Type of concept, 83.3% is a concept based on principle; and 16.6% concepts that state the process. Meanwhile, the science process skills that can be developed based on concept analysis are the ability to observe, calculate, measure, predict, interpret, hypothesize, apply, classify, and inference.

  11. A new consistent definition of the homogenized diffusion coefficient of a lattice, limitations of the homogenization concept, and discussion of previously defined coefficients

    Deniz, V.C.

    1980-01-01

    The problem concerned with the correct definition of the homogenized diffusion coefficient of a lattice, and the concurrent problem of whether or not a homogenized diffusion equation can be formally set up, is studied by a space-energy-angle dependent treatment for a general lattice cell using an operator notation which applies to any eigen-problem. A new definition of the diffusion coefficient is given, which combines within itself the individual merits of the two definitions of Benoist. The relation between the new coefficient and the ''uncorrected'' Benoist coefficient is discussed by considering continuous-spectrum and multi-group diffusion equations. Other definitions existing in the literature are briefly discussed. It is concluded that a diffusion coefficient should represent only leakage effects. A comparison is made between the homogenization approach and the approach via eigen-coefficients, and brief indications are given of a possible scheme for the latter. (author)

  12. From basic needs to basic rights.

    Facio, A

    1995-06-01

    After arriving at an understanding that basic rights refer to all human needs, it is clear that a recognition of the basic needs of female humans must precede the realization of their rights. The old Women in Development (WID) framework only understood women's needs from an androcentric perspective which was limited to practical interests. Instead, women's primary need is to be free from their subordination to men. Such an understanding places all of women's immediate needs in a new light. A human rights approach to development would see women not as beneficiaries but as people entitled to enjoy the benefits of development. Discussion of what equality before the law should mean to women began at the Third World Conference on Women in Nairobi where the issue of violence against women was first linked to development. While debate continues about the distinction between civil and political rights and economic, social, and cultural rights, the realities of women's lives do not permit such a distinction. The concept of the universality of human rights did not become codified until the UN proclaimed the Universal Declaration of Human Rights in 1948. The declaration has been criticized by feminists because the view of human rights it embodies has been too strongly influenced by a liberal Western philosophy which stresses individual rights and because it is ambiguous on the distinction between human rights and the rights of a citizen. The protection of rights afforded by the Declaration, however, should not be viewed as a final achievement but as an ongoing struggle. International conferences have led to an analysis of the human-rights approach to sustainable development which concludes that women continue to face the routine denial of their rights. Each human right must be redefined from the perspective of women's needs, which must also be redefined. Women must forego challenging the concept of the universality of human rights in order to overcome the argument of cultural

  14. A new consistent definition of the homogenized diffusion coefficient of a lattice, limitations of the homogenization concept, and discussion of previously defined coefficients

    Deniz, V.C.

    1978-01-01

    The problem concerned with the correct definition of the homogenized diffusion coefficient of a lattice, and the concurrent problem of whether or not a homogenized diffusion equation can be formally set up, is studied by a space-energy angle dependent treatment for a general lattice cell; using an operator notation which applies to any eigen-problem. It is shown that the diffusion coefficient should represent only leakage effects. A new definition of the diffusion coefficient is given, which combines within itself the individual merits of each of the two definitions of Benoist, and reduces to the 'uncorrected' Benoist coefficient in certain cases. The conditions under which a homogenized diffusion equation can be obtained are discussed. A compatison is made between the approach via a diffusion equation and the approach via the eigen-coefficients of Deniz. Previously defined diffusion coefficients are discussed, and it is shown that the transformed eigen-coefficients proposed by Gelbard and by Larsen are unsuitable as diffusion coefficients, and that the cell-edge normalization of the Bonalumi coefficient is not physically justifiable.

  15. Sentiency, bioethics and animal welfare: concepts that need to be discussed in higher education to change the teaching and researching paradigm

    Anderson do Prado Duzanski

    2015-12-01

    Full Text Available This study investigated the knowledge of students of Veterinary Medicine and Biological Sciences of the State University of Northern Paraná, Campus Luiz Meneghel, on the ethical and legal guidelines of animal experimentation, as well as the possibility of substitute methods for using sentient animals in classes and scientific practices. The research involved 162 freshman students and graduating students, aged 17 to 32 years. The students responded to the questionnaire containing objective and subjective questions, and the answers were analysed by descriptive statistics. It was observed that 87% of the students were unaware of the concept of the “3Rs” and 81.5% did not know the existence of alternative methods that can replace the use of live animals in studies. In addition, only 24.7% of respondents reported they had studied “bioethics” before graduation. However, 94.3% and 96.2% of the students from veterinary medicine and biological sciences, respectively, considered it important to insert animal welfare and bioethics in the curriculum of such courses. The results demonstrated that the ethical and statutory guidelines that rule the use of animals in scientific experiments and in classes are unknown even among senior students and there is still great resistance to the exclusion of animal models. Thus, it is important that animal welfare and bioethics remain in the curriculum in higher education through the insertion of such subjects, even as elective courses that aim to work with methodologies and innovative strategies in synergistic action with ethics committees for animal use, which are responsible for analysing, guiding and supervising the relevance of animal use in education and research. Therefore, the curriculum will be able to achieve rationalization in the use of animal models, the sustainable and “humanitarian” development of teaching and research, and the training of more conscious and ethical professionals, perceptions

In this paper, we present......Much research has focused on studying complex phenomena through their reflection in social media, from drawing neighborhood boundaries to inferring relationships between medicines and diseases. While it is generally recognized in the social sciences that such studies should be conditioned on gender...... a simple framework for specifying and implementing common social media analyses that makes it trivial to inspect and condition on contextual information.

  17. Discussion of the concept of safety indicators from the point of view of TfUX2 accident sequence for Forsmark 3

    Bujor, A.

    1991-01-01

    This paper contains general considerations on the safety indicators, with details at the system level and for the operator actions. For the system analysis, a modular analysis at a low detailed level is proposed (Module System Approach) in order to emphasize the safety related aspects at the subsystem (module) level. The operator actions are divided in ''active actions'' (actions in the control room during incident/accident situations) and ''passive actions'' (actions during tests, maintenance, repairs, etc.) and are analysed separately. In the second part, a discussion of a possible way to apply some SI to the TfUX2 accident sequence for FORSMARK-3, is done. For the analysis of the Auxiliary Feedwater Systems (AFWS) an equation is proposed to derive target values for the failure probability on demand at the train level, given the target value at the system level, including the common cause failures between the redundant trains.

    Full Text Available Die Forderung, die soziologisch feministische Analyse um die Ungleichheitsdimensionen Schicht/Klasse und ethnische Zugehörigkeiten zu erweitern, wird vor allem in den USA schon seit einigen Jahren erhoben. In diesem Sammelband wird der Versuch gemacht, den Stand der Diskussion in den women’s und gender studies und die theoretischen wie empirischen Fortschritte der letzten zehn Jahre in den USA zu dokumentieren.In this handbook the authors attempt to summarize the state of gender studies in the social sciences in the United States. Build on an previous overview twelve years ago (Analyzing Gender, 1987, edited by Beth B. Hess und Myra Marx Ferree the goal of this collection is to “to re-vision gender with even more sophisticated lenses”, by focussing on the research done in the previous decade and by encouraging thinking about how the questions feminists ask have changed. The focus of this collection is to take gender seriously as both process and structure, from the individual to social level of analysis, no longer to take dichotomous gender for granted, und to discuss a new framing of the intersectionality of gender, race, and class.

  19. Basic principles

    Wilson, P.D.

    1996-01-01

    Some basic explanations are given of the principles underlying the nuclear fuel cycle, starting with the physics of atomic and nuclear structure and continuing with nuclear energy and reactors, fuel and waste management and finally a discussion of economics and the future. An important aspect of the fuel cycle concerns the possibility of ''closing the back end'' i.e. reprocessing the waste or unused fuel in order to re-use it in reactors of various kinds. The alternative, the ''oncethrough'' cycle, discards the discharged fuel completely. An interim measure involves the prolonged storage of highly radioactive waste fuel. (UK)

  20. Modeling plant density and ponding water effects on flooded rice evapotranspiration and crop coefficients: critical discussion about the concepts used in current methods

    Aschonitis, Vassilis; Diamantopoulou, Maria; Papamichail, Dimitris

    2018-05-01

    The aim of the study is to propose new modeling approaches for daily estimations of crop coefficient K c for flooded rice ( Oryza sativa L., ssp. indica) under various plant densities. Non-linear regression (NLR) and artificial neural networks (ANN) were used to predict K c based on leaf area index LAI, crop height, wind speed, water albedo, and ponding water depth. Two years of evapotranspiration ET c measurements from lysimeters located in a Mediterranean environment were used in this study. The NLR approach combines bootstrapping and Bayesian sensitivity analysis based on a semi-empirical formula. This approach provided significant information about the hidden role of the same predictor variables in the Levenberg-Marquardt ANN approach, which improved K c predictions. Relationships of production versus ET c were also built and verified by data obtained from Australia. The results of the study showed that the daily K c values, under extremely high plant densities (e.g., for LAI max > 10), can reach extremely high values ( K c > 3) during the reproductive stage. Justifications given in the discussion question both the K c values given by FAO and the energy budget approaches, which assume that ET c cannot exceed a specific threshold defined by the net radiation. These approaches can no longer explain the continuous increase of global rice yields (currently are more than double in comparison to the 1960s) due to the improvement of cultivars and agriculture intensification. The study suggests that the safest method to verify predefined or modeled K c values is through preconstructed relationships of production versus ET c using field measurements.

    Stefanita, Carmen-Gabriela

    2012-01-01

    This textbook is aimed at engineering students who are likely to come across magnetics applications in their professional practice. Whether designing lithography equipment containing ferromagnetic brushes, or detecting defects in aeronautics, some basic knowledge of 21st century magnetism is needed. From the magnetic tape on the pocket credit card to the read head in a personal computer, people run into magnetism in many products. Furthermore, in a variety of disciplines tools of the trade exploit magnetic principles, and many interdisciplinary laboratory research areas cross paths with magnetic phenomena that may seem mysterious to the untrained mind. Therefore, this course offers a broad coverage of magnetism topics encountered more often in this millenium, revealing key concepts on which many practical applications rest. Some traditional subjects in magnetism are discussed in the first half of the book, followed by areas likely to spark the curiosity of those more interested in today’s technological achi...

  3. Basic standards for radiation protection

    Webb, G.A.M.

    1982-01-01

    The basic standards for radiation protection have been based, for many years, on the recommendations of the International Commission of Radiological Protection. The three basic standards recommended by the Commission may be summarized as ''justification, optimization of protection and adherence to dose limitations. The applications of these basic principles to different aspects of protection are briefly summarized and the particular ways in which they have been applied to waste described in more detail. The application of dose limits, both in the control of occupational exposure and in regulating routine discharges of radioactive effluents is straight forward in principle although the measurement and calculational requirements may be substantial. Secondary standards such as derived limits may be extremely useful and the principles underlying their derivation will be described. Optimization of protection is inherently a more difficult concept to apply in protection and the various techniques used will be outlined by with particular emphasis on the use of cost benefit analysis are recommended by the ICRP. A review will be given of the problems involved in extending these basic concepts of the ICRP to probabilistic analyses such as those required for assessing the consequences of accidents or disruptive events in long term repositories. The particular difficulties posed by the very long timescales involved in the assessment of waste management practices will be discussed in some detail. (orig./RW)

  15. Empowerment: a conceptual discussion.

    Tengland, Per-Anders

    2008-06-01

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Vorobieva, A.E.

    2015-07-01

    Full Text Available An analysis of Russian and foreign ways of understanding the phenomenon of self-determination has been performed. It has been found that the concept of individual and group self-determination by A.L. Zhuravlev and A.B. Kupreichenko is the most developed in modern Russian psychological science. Using the concept as a basis, the conceptual schemes (made by A.E. Vorobieva and A.A. Akbarova of studies of personal, moral, social and economic self-determination were considered as the examples of the basic and special types of self-determination. Moral self-determination was studied with questions about ideas of morality, moral strategies and personality orientation, attitude toward unethical phenomena, ability for self-regulation and emotional intellect. Social and economic self-determination were studied with questions that show one’s social level, satisfaction with economic and social status and their dynamics, a valuation of favorable circumstances for an increase of status and economic activity. Value and anti-value, spheres and forms of showing of social and living personality’s activity were also determined. Fundamental differences (variability, success criteria, implementation in behavior, a level of ability to control a process, the role of external factors and similarities (successfulness, a formation level, a range, dynamics, conceptions, strategy, values, factors between the components of the conceptual schemes of these types of selfdetermination were identified. The principles of studying (proportion of basic and specific types of self-determination, a display of resultative, procedural and formal-dynamic characteristics, consideration of factors of different levels of basic and special types of self-determination were suggested.

    2009-01-01

      Concept theory is an extremely broad, interdisciplinary and complex field of research related to many deep fields with very long historical traditions without much consensus. However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge...... organizing systems (e.g. classification systems, thesauri and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe......, evaluate and use such systems. Based on "a post-Kuhnian view" of paradigms this paper put forward arguments that the best understanding and classification of theories of concepts is to view and classify them in accordance with epistemological theories (empiricism, rationalism, historicism and pragmatism...

  17. Regulação em saúde: análise de conceitos fundamentais Setting health guidelines: analysis of basic concepts

    Janice Dornelles de Castro

    2002-06-01

    Full Text Available As atribuições do Estado com relação à garantia dos direitos de acesso aos cuidados de saúde ampliaram-se após a promulgação da Constituição Federal de 1988 que introduziu a garantia do acesso universal e integral. Além disso, a efetiva política de descentralização das ações de saúde para estados e, principalmente, para os municípios gerou a necessidade de debater sobre responsabilidades e atribuições dos diferentes níveis de governo, dos cidadãos, do Estado e dos setores público e privado. E por fim, as políticas públicas voltadas à redução da intervenção do Estado na economia também trazem à tona essa questão polêmica. Nesta medida, propusemo-nos a discutir neste artigo as falhas de mercado que ocorrem no setor saúde e justificam a intervenção do Estado para alcançar a otimização na alocação e na distribuição dos recursos.As a result of the 1988 Federal Constitution changes in public health policies, e.g. the guarantee to the whole society to universal and integral access to health care, the duties of the State concerning those specific matters have increased considerably. Moreover, the effective policy of decentralisation of resolutions in health matters for states and over all for municipalities urged a new discussion to take place on the subjects of responsibilities and duties for individuals, different levels of the Government, citizens, the state and the public and private spheres. Finally, public policies which support "the withdrawal of the State´s intervention in economy affairs" also bring up this polemic subject. We aimed to discuss in this article, in the context suggested above, the health demand and the reasons why the market is inefficient to optimising the allocation of recourses.

    2014-08-01

    Here we discuss how the concept and the name of cytoskeleton were generated and started to evolve over the last two centuries into what is presently a basic topic of modern biology. We also attempt to describe some facets of the emergence of cytoskeleton component characterization in which our laboratory was in part involved. © 2014 Wiley Periodicals, Inc.

  19. Basic principles of quality assurance

    Stauffer, M.

    1977-01-01

    After a brief review of the origin of the 'quality concept' and the historical development of quality assurance, questions such as 'what is QA' and 'why is QA so important in nuclear technology' as well as definitions and main requirements of relevant QA codes and standards are presented and discussed. By means of a project realization schematic, tasks, duties, responsibilities, and possible QA organigrammes as well as QA programme and manual requirements are explained and compared. From a QA point of view, it is shown that no basic difference exists between design and production or construction control activities. Special emphasis is layed upon active owner's participation in the implementation of QA programmes for NPP and the advantages offered are described and illustrated by typical examples. (RW) [de

  20. Basic sanitation policy in Brazil: discussion of a path.

    Sousa, Ana Cristina A de; Costa, Nilson do Rosário

    2016-01-01

    This article demonstrates that the position of dominance enjoyed by state sanitation companies dictates the public policy decision-making process for sanitation in Brazil. These companies' hegemony is explained here through the analysis of a path that generated political and economic incentives that have permitted its consolidation over time. Through the content analysis of the legislation proposed for the sector and the material produced by the stakeholders involved in the approval of new regulations for the sector in 2007, the study identifies the main sources of incentive introduced by the adoption of the National Sanitation Plan, which explain certain structural features of the current sanitation policy and its strong capacity to withstand the innovations proposed under democratic rule.

  7. Basic science research in urology training.

    Eberli, D; Atala, A

    2009-04-01

    The role of basic science exposure during urology training is a timely topic that is relevant to urologic health and to the training of new physician scientists. Today, researchers are needed for the advancement of this specialty, and involvement in basic research will foster understanding of basic scientific concepts and the development of critical thinking skills, which will, in turn, improve clinical performance. If research education is not included in urology training, future urologists may not be as likely to contribute to scientific discoveries.Currently, only a minority of urologists in training are currently exposed to significant research experience. In addition, the number of physician-scientists in urology has been decreasing over the last two decades, as fewer physicians are willing to undertake a career in academics and perform basic research. However, to ensure that the field of urology is driving forward and bringing novel techniques to patients, it is clear that more research-trained urologists are needed. In this article we will analyse the current status of basic research in urology training and discuss the importance of and obstacles to successful addition of research into the medical training curricula. Further, we will highlight different opportunities for trainees to obtain significant research exposure in urology.

  8. Geophysical worldwide networks: basic concepts and techniques

    Ruzie, G.; Baubron, G.

    1997-01-01

    The detection of nuclear explosions around the globe requires the setting up of networks of sensors on a worldwide basis. Such equipment should be able to transmit on-line data in real-time or pseudo real-time to a center or processing centers. The high level of demanded reliability for the data (generally better than 99 %) also has an impact on the accuracy and precision of the sensors and the communications technology, as well as the systems used for on-line checking. In the light of these requirements, DAM has developed a data gathering network based on the principle of VSTA duplex links which ensures the on-line transmission of data and operational parameters towards the Processing Centre via a hub. In the other direction, the Centre can act on a number of parameters in order to correct them if necessary, or notify the local maintenance team. To optimize the reliability of the main components of this system, the detection stations as well as their associated beacons have low consumption and can be supplied by solar panels, thus facilitating the installation of the networks. The seismic network on the French national territory is composed of 40 stations built on the principles outlined above. In order to gather data from stations established outside France, DAM is planning to use an analogue system to transmit data in on-line as well as off-line mode. (authors)

  12. [Basic concept in computer assisted surgery].

    Merloz, Philippe; Wu, Hao

    2006-03-01

    To investigate application of medical digital imaging systems and computer technologies in orthopedics. The main computer-assisted surgery systems comprise the four following subcategories. (1) A collection and recording process for digital data on each patient, including preoperative images (CT scans, MRI, standard X-rays), intraoperative visualization (fluoroscopy, ultrasound), and intraoperative position and orientation of surgical instruments or bone sections (using 3D localises). Data merging based on the matching of preoperative imaging (CT scans, MRI, standard X-rays) and intraoperative visualization (anatomical landmarks, or bone surfaces digitized intraoperatively via 3D localiser; intraoperative ultrasound images processed for delineation of bone contours). (2) In cases where only intraoperative images are used for computer-assisted surgical navigation, the calibration of the intraoperative imaging system replaces the merged data system, which is then no longer necessary. (3) A system that provides aid in decision-making, so that the surgical approach is planned on basis of multimodal information: the interactive positioning of surgical instruments or bone sections transmitted via pre- or intraoperative images, display of elements to guide surgical navigation (direction, axis, orientation, length and diameter of a surgical instrument, impingement, etc. ). And (4) A system that monitors the surgical procedure, thereby ensuring that the optimal strategy defined at the preoperative stage is taken into account. It is possible that computer-assisted orthopedic surgery systems will enable surgeons to better assess the accuracy and reliability of the various operative techniques, an indispensable stage in the optimization of surgery.

  13. Luminescence basic concepts, applications and instrumentation

    Virk, Hardev Singh

    2014-01-01

    The word luminescence was first used by a German physicist, Eilhardt Wiedemann, in 1888. He also classified luminescence into six kinds according to the method of excitation. No better basis of classification is available today. He recognized photoluminescence, thermoluminescence, electroluminescence, crystalloluminescence, triboluminescence, and chemiluminescence. The designations are obvious, characterized by the prefix. This Volume consists of 9 Chapters, including 8 Review Papers and one Case Study. The first two papers are based on OLEDs. Organic light emitting diodes (OLEDs) have been th

  14. Basic concepts and definitions of clinical management

    Angélica Román

    2012-06-01

    Full Text Available Management is leading, administering resources, and achieving the goals and objectives that have been set. In the Chilean health care system, management can be subdivided in three main levels – macro-management, meso-management and micro-management. Managing health care is also about epidemiological changes, information and technology innovations, patient groups demanding better services, but mostly about a huge escalation in costs that is not necessarily substantiated by evidence on more efficiency in health outcomes.Clinical management is more than a management tool. It is a cultural change that will provide new values to professional practice and to the organization as a whole. However, clinical management demands more commitment on behalf of the human teams that need to learn how to lead and to be led. These teams will be called upon to help in the decision-making process for the betterment of the institution.

  18. Radiation protection. Basic concepts of ICRP

    Saito, Tsutomu; Hirata, Hideki

    2014-01-01

    The title subject is easily explained. Main international organizations for radiation protection are United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), International Commission on Radiological Protection (ICRP) and International Atomic Energy Agency (IAEA). The UNSCEAR objectively summarizes and publishes scientific findings; ICRP, an NGO, takes part in recommending the radiological protection from the expertized aspect; and IAEA, a UN autonomy, aims at peaceful usage of atomic power. These organizations support the legal regulation and standard of nations. The purpose of the ICRP recommendation (Pub. 103, 2007) is to contribute to the appropriate protection of radiation hazardous effects, which are assumed to be linearly proportional (the model of linear no-threshold, LNT) that radiation risk exists even at the lowest dose. When a change in the single cell results in hazardous alteration, the causative effects are called stochastic effects, which include the mutation leading to cancer formation and genetic effect in offspring (not observed in man). ICRP says the validity of LNT for the stochastic effects essentially from the protective aspect, although epidemiological data support it at >100 mSv exposure. The deterministic effects are caused by loss of cell itself or of its function, where the threshold is defined to be the dose causing >1% of disorder or death. Radiation protective system against exposure is on the situation (programmed, emergent and natural), category (occupational, public and medical) and 3 principles of justification, optimization and application of dose limit.

  8. Lateral Concepts

    Gad, Christopher; Bruun Jensen, casper

    2016-01-01

    This essay discusses the complex relation between the knowledges and practices of the researcher and his/her informants in terms of lateral concepts. The starting point is that it is not the prerogative of the (STS) scholar to conceptualize the world; all our “informants” do it too. This creates...... the possibility of enriching our own conceptual repertoires by letting them be inflected by the concepts of those we study. In a broad sense, the lateral means that there is a many-to-many relation between domains of knowledge and practice. However, each specific case of the lateral is necessarily immanent...... to a particular empirical setting and form of inquiry. In this sense lateral concepts are radically empirical since it locates concepts within the field. To clarify the meaning and stakes of lateral concepts, we first make a contrast between lateral anthropology and Latour’s notion of infra-reflexivity. We end...

  16. Basic Emotions: A Reconstruction

    Mason, William A.; Capitanio, John P.

    2016-01-01

    Emotionality is a basic feature of behavior. The argument over whether the expression of emotions is based primarily on culture (constructivism, nurture) or biology (natural forms, nature) will never be resolved because both alternatives are untenable. The evidence is overwhelming that at all ages and all levels of organization, the development of emotionality is epigenetic: The organism is an active participant in its own development. To ascribe these effects to “experience” was the best that could be done for many years. With the rapid acceleration of information on how changes in organization are actually brought about, it is a good time to review, update, and revitalize our views of experience in relation to the concept of basic emotion.

  17. Basic electronic circuits

    Buckley, P M

    1980-01-01

    In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli­ cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encounte...

  19. Ethical analysis of the concept of disability.

    Vehmas, Simo

    2004-06-01

    The concept of disability from an ethical viewpoint was examined. Whether disability results from the way society is built and the way ideas and judgments considering disability are established in a communal interaction was discussed (i.e., is disability socially created and constructed?). Although views on disability emphasizing its social nature are basically sound, they are also insufficient because they fail to consider the normative dimension attached to the concept of disability. The core of the concept of disability is ethical, which is why a moral philosophical examination of the concept is needed. Three possible ethical theories of disability (universal, objective, subjectivist, and communitarian) are briefly presented and discussed and a preliminary outline of a basis for a sound ethical model of disability presented.

    2011-12-01

    In this report, the development of a methodological proposal which approaches basic concepts of astronomy-grounded pedagogically on Meaningful Learning is described. The proposal, which consists of four meetings, was developed by teachers and academics of the course of Professor in Physics of the University of Passo Fundo (UPF), through an extension course to a group of highschool students of a public school of the town of Passo Fundo, RS. The work was focused into basic concepts of astronomy. The signs of Meaningful Learning have been obtained by means of research and evaluation tools that were applied at the end of each meeting. The evaluation of the proposal has been conducted by means of a final questionnaire which was answered by the participants at the end ofthe development of activities. By means of the results obtained from the different instruments, and the comments made by the participants during the activities and by means of the high rates of approval obtained in the final questionnaire, we think that the proposal reached the established goals and it may be repeated with the certainty of success. En este relato se describe una propuesta de desarrollo metodológico que aborda conceptos básicos de astronomía fundamentada pedagógicamente en el Aprendizaje Significativo. La propuesta que comprende cuatro encuentros, fue desarrollada por profesores y académicos del curso de Licenciatura en Física de la Universidad de Passo Fundo (UPF), a través de un curso de extensión para un grupo de Liceo del 6º año de una Escuela Pública de la ciudad de Passo Fundo/RS. El trabajo tuvo como eje principal los "conceptos básicos de astronomía". Los indicios de Aprendizaje Significativo fueron obtenidos por instrumentos de pesquisa y evaluación, siempre aplicados después de cada encuentro. La evaluación de la propuesta fue hecha a través de un cuestionario final y contestado por los participantes al finalizar el desarrollo de actividades. Por los resultados

  9. Instrument basics

    Jenkins, R.

    1999-01-01

    Full text: The earliest powder diffractometers date back to the mid-1930s when Le Galley described the use of a point source, line receiving slit, system. The modern parafocusing system was developed by Parrish et al, in the mid to late 1940s, and most diffractometers today employ this same parafocusing (Bragg-Brentano) geometry. With the arrival of the synchrotron more than a decade ago, many new innovations have come along, both in data collection and data processing. In addition, interest in thin film technology has spawned a new breed of diffractometer which used low glancing angle optics. However, as far as the average, stand-alone, diffractometer systems were concerned, the only real innovation has been along the line of addition of various types of monochromatization device, special types of proportional detector, automated slit systems, multi-sample handling devices and so on. This workshop reviews the optical arrangement of typical 'routine' diffractometers, and discusses the advantages and disadvantages of each.

  11. Astrophysical Concepts

    Harwit, Martin

    2006-01-01

    This classic text, aimed at senior undergraduates and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depth to give the reader a quantitative understanding of the subject. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail: it provides a series of astrophysical sketches. For this fourth edition, nearly every part of the text has been reconsidered and rewritten, new sections have been added to cover recent developments, and others have been extensively revised and brought up to date. The book begins with an outline of the scope of modern astrophysics and enumerates some of the outstanding problems faced in the field today. The basic physics needed to tackle these questions are developed in the next few chapters using specific astronomical processes as examples. The second half of the book enlarges on these topics and shows how we can obtain quantitative insight into the structure and evolution of...

  13. Discussion in Postsecondary Classrooms

    Curt Dudley-Marling

    2013-11-01

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

  14. A identidade profissional dos terapeutas ocupacionais: considerações a partir do conceito de estigma de Erving Goffman Professional identity of occupational therapists: a discussion based on Erving Goffman's concept of stigma

    Claudia Reinoso Araújo de Carvalho

    2012-06-01

    Full Text Available Este trabalho relaciona a noção de identidade profissional da Terapia Ocupacional com a obra Estigma: notas sobre a manipulação da identidade deteriorada, do sociólogo canadense Erving Goffman. Busca-se articular ao campo profissional um conjunto específico de conceitos que, na perspectiva teórica do interacionismo simbólico, foram desenvolvidos pelo autor. Tais conceitos relacionados à informação social são aplicados a situações cotidianas da profissão, de modo que é possível constatar que as manipulações da identidade acontecem no âmbito profissional de forma muito similar ao descrito por Goffman em seu livro. A análise é complementada por artigos e estudos acadêmicos nacionais e internacionais do campo da Terapia Ocupacional sobre o tema da identidade profissional. Ainda que o estudo da identidade profissional exija diferentes enfoques, conclui-se que as ideias do referido autor contribuem significativamente nas reflexões acerca do tema.This work relates the notion of Occupational Therapy professional identity with the book "Stigma: notes on the management of spoiled identity", written by Canadian sociologist Erving Goffman. An articulation is tried between the professional field and a specific set of concepts which were developed by the author in the theoretical perspective of symbolic interactions. Such concepts, related to social information, are applied to professional everyday situations so that it is possible to verify that the manipulations occur in the professional identity in a very similar way to those described by Goffman in his book. The analysis is complemented by national and international papers and academic studies in the field of Occupational Therapy, on the theme of professional identity. Although the study of professional identity requires different approaches, it is possible to conclude that the ideas of the author present a significant contribution to the reflections on the subject.

  16. Uncertainties about the safety of disposal leading to a wish to keep alternatives open. Discussion on the concepts 'storage' ('wait and see') vs. 'disposal' and 'retrievable disposal' vs. 'definitive disposal'

    Norrby, S.

    2000-01-01

    Uncertainties about the safety of final disposal may lead to unwillingness to take decisions about waste management issues that may seem to be non-reversible. This has lead to proposals that we should wait with decisions on final measures and instead store the waste for some period of time. Also the possibility of retrieval may lead to decisions not to go for permanent disposal but instead to retrievable disposal. These aspects and the pros and cons are discussed both from a more general perspective and also with some reflections from the Swedish programme for nuclear waste management and disposal. (author)

    2005-01-01

    Based on the research content of post-remote sensing application technology for uranium exploration, a preliminary discussion on the correlation between RS information and geophysical information from gravity, aero-magnetics, aero-radioactivity is made on five aspects: physical meaning, depth of geological rule meaning, time and phase, planar pattern and inter-reaction mechanism. It creates a good beginner for deeply studying the correlation in quality and quantity between RS information from post-remote sensing application technology and other geologic information.

  18. The concept of work ability.

    Tengland, Per-Anders

    2011-06-01

    The concept of "work ability" is central for many sciences, especially for those related to working life and to rehabilitation. It is one of the important concepts in legislation regulating sickness insurance. How the concept is defined therefore has important normative implications. The concept is, however, often not sufficiently well defined. AIM AND METHOD The objective of this paper is to clarify, through conceptual analysis, what the concept can and should mean, and to propose a useful definition for scientific and practical work. RESULTS Several of the defining characteristics found in the literature are critically scrutinized and discussed, namely health, basic standard competence, occupational competence, occupational virtues, and motivation. These characteristics are related to the work tasks and the work environment. One conclusion is that we need two definitions of work ability, one for specific jobs that require special training or education, and one for jobs that most people can manage given a short period of practice. Having work ability, in the first sense, means having the occupational competence, the health required for the competence, and the occupational virtues that are required for managing the work tasks, assuming that the tasks are reasonable and that the work environment is acceptable. In the second sense, having work ability is having the health, the basic standard competence and the relevant occupational virtues required for managing some kind of job, assuming that the work tasks are reasonable and that the work environment is acceptable. CONCLUSION These definitions give us tools for understanding and discussing the complex, holistic and dynamic aspects of work ability, and they can lay the foundations for the creation of instruments for evaluating work ability, as well as help formulate strategies for rehabilitation.

  19. Encouraging Classroom Discussion

    Robert Joseph McKee

    2014-10-01

    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

  20. Climate Change: reflections to support this discussion in Physics classes

    Agenor Pina Pina

    2010-03-01

    Full Text Available The subject of Climate Changes is an everyday issue in our lives, due to media network information. Many questions about this theme are presented and discussed in a large sort of massive communication media. Despite this situation, we have to say that many of these issues are open subjects for the international scientific community, without a common sense about the causes and consequences of climate changes. In this context, Physics offers theoretical concepts and a way of modeling nature to produce some knowledge about this subject mainly because it is a basic science. From this point of view, the issue of climate changes can be considered a specially useful subject to illustrate these physical concepts by Physics teachers, to motivate students or to elaborate new educational proposals. In order to provide some tools to teach this subject in High School Physics classes, this paper offers two perspectives: to point out some physical considerations about this theme and to discuss a few uncertainties and controversies related to climate changes. In a specific way we will present some considerations about the energy balance in the Sun-Earth system, the greenhouse effect and the concept of the mean temperature of the Earth.

  1. Basic safety principles for nuclear power plants

    1988-01-01

    Nuclear power plant safety requires a continuing quest for excellence. All individuals concerned should constantly be alert to opportunities to reduce risks to the lowest practicable level. The quest, however, is most likely to be fruitful if it is based on an understanding of the underlying objectives and principles of nuclear safety, and the way in which its aspects are interrelated. This report is an attempt to provide a logical framework for such an understanding. The proposed objectives and principles of nuclear safety are interconnected and must be taken as a whole; they do not constitute a menu from which selection can be made. The report takes account of current issues and developments. It includes the concept of safety objectives and the use of probabilistic safety assessment. Reliability targets for safety systems are discussed. The concept of a 'safety culture' is crucial. Attention has been paid to the need for planning for accident management. The report contains objectives and principles. The objectives state what is to be achieved; the principles state how to achieve it. In each case, the basic principle is stated as briefly as possible. The accompanying discussion comments on the reasons for the principle and its importance, as well as exceptions, the extent of coverage and any necessary clarification. The discussion is as important as the principle it augments. 4 figs

  5. A Discussion on the Concept of Water Resources from the Perspective of the Most Stringent Water Management System%最严格水资源管理制度视野下水资源概念探讨

    胡德胜

    2015-01-01

    In order to solve the increasingly serious water problems and solve this major bottleneck in China’s sustainable economic and so-cial development,China has decided to establish and implement the most stringent water management system. In order to refine and imple-ment this system,it is necessary to clarify the basic term of“water resources”with its definition and extension according to legal theory. By comparing and analyzing different understandings and/or legal definitions of“water resources”,at home and abroad,from different disci-plines,and from different legal systems in different countries,based on the perspective of the most stringent water management system,the scope of“water resources”should be legitimately delimited in a way of considering the substance of water itself as well as its relevant roles and functions comprehensively,and therefore:(i)in terms of quantity,“water resources”should be limited to freshwater in principle,only surface water and groundwater should be calculated,and atmospheric water,soil water and green water should be excluded;(ii)the man-agement of water quality and self-purification capacity should be emphasized;(iii)the objects of the most stringent water management sys-tem should include hydraulic power resources,water transport resources and those carrier of water resources,such as river/waterway,lake, wetland,reservoir/dam,pond,spring,well,glacier,etc.%为了解决日益严峻的水问题,我国决定建立并正在实施最严格水资源管理制度。为了细化和便于实施最严格水资源管理制度,需要对“水资源”这一基础术语的内涵和外延有一个符合法学理论的界定。通过比较和分析国内外、不同学科、不同国家法律对于水资源的不同认识、理解或者法律界定,基于最严格水资源管理制度的视野,需要综合考虑水物质及与其有关的各种作用和功能,对水资源的范围予以合理界定:在数量方面限

    A A Abbasova

    2015-12-01

    Full Text Available The article is devoted to the importance of selecting the optimal methods of stimulation and motivation for learning. In modern conditions it is very important that the teacher did not give the students ready knowledge, but pointed out the way for the acquisition of knowledge, taught them to gain knowledge. This demands from the philologist the choice of effective forms of working with texts of different types and styles of speech, listening, speaking. In this connection a special attention should be paid to the lessons of speech development. There is a special group of methods to stimulate the development of communicative competence. Among them, the method of discussion, which is increasingly being used during the Russian language lessons. The specificity of using this method in class for teaching Russian as a foreign language, its basic functions (teaching, developing, educating are considered. The key rules for conducting a discussion at the Russian language classes, the main and additional functions-roles of the teacher, the participants, the minute-taker are analyzed. The advantages of the discussion in Russian in comparison to the discussion in the students’ native language are summarized.

  7. Basic category theory

    Leinster, Tom

    2014-01-01

    At the heart of this short introduction to category theory is the idea of a universal property, important throughout mathematics. After an introductory chapter giving the basic definitions, separate chapters explain three ways of expressing universal properties: via adjoint functors, representable functors, and limits. A final chapter ties all three together. The book is suitable for use in courses or for independent study. Assuming relatively little mathematical background, it is ideal for beginning graduate students or advanced undergraduates learning category theory for the first time. For each new categorical concept, a generous supply of examples is provided, taken from different parts of mathematics. At points where the leap in abstraction is particularly great (such as the Yoneda lemma), the reader will find careful and extensive explanations. Copious exercises are included.

  8. Energy the basics

    Schobert, Harold

    2013-01-01

    People rarely stop to think about where the energy they use to power their everyday lives comes from and when they do it is often to ask a worried question: is mankind's energy usage killing the planet? How do we deal with nuclear waste? What happens when the oil runs out? Energy: The Basics answers these questions but it also does much more. In this engaging yet even-handed introduction, readers are introduced to: the concept of 'energy' and what it really means the ways energy is currently generated and the sources used new and emerging energy technologies such as solar power and biofuels the impacts of energy use on the environment including climate change Featuring explanatory diagrams, tables, a glossary and an extensive further reading list, this book is the ideal starting point for anyone interested in the impact and future of the world's energy supply.

  10. The Concept of Carrying Capacity in Tourism

    Josef Zelenka

    2014-05-01

    Full Text Available Carrying capacity is often pragmatically, theoretically as well as purely intuitively considered as a concept in the context of tourism sustainability. The carrying capacity application has the greatest potential in protected areas, in frequently visited cultural and natural attractions, and in relation to sustaining of the lifestyle of the local community and tourism destination potential in general. Despite its importance, partial applications, determination of basic theoretical principles, and specifying connection to the other theoretical concepts in tourism (particularly destination life cycle, LAC concept, visitors management, there still is a rightful opinion of some authors suggesting that there is no consistent theory of tourism carrying capacity. This theory would be the base for sophisticated practical carrying capacity applications. This paper is therefore focused on introduction of the theoretical concept of carrying capacity, which can be discussed and possibly further elaborated.

  11. Uranium: a basic evaluation

    Crull, A.W.

    1978-01-01

    All energy sources and technologies, including uranium and the nuclear industry, are needed to provide power. Public misunderstanding of the nature of uranium and how it works as a fuel may jeopardize nuclear energy as a major option. Basic chemical facts about uranium ore and uranium fuel technology are presented. Some of the major policy decisions that must be made include the enrichment, stockpiling, and pricing of uranium. Investigations and lawsuits pertaining to uranium markets are reviewed, and the point is made that oil companies will probably have to divest their non-oil energy activities. Recommendations for nuclear policies that have been made by the General Accounting Office are discussed briefly

    Full Text Available Defining and recognizing a species has been a controversial issue for a long time. To determine the variation and the limitation between species, many concepts have been proposed. When a taxonomist study a particular taxa, he/she must adopted a species concept and provide a species limitation to define this taxa. In this paper some of species concepts are discussed starting from the typological species concepts to the phylogenetic concept. Positive and negative aspects of these concepts are represented in addition to their application. Keywords: Species concept, Species limitation, Species, Taxonomy, Classification

    The author discusses the terms 'remaining risk to be accepted' and 'remainder of the aggregate risk', and explains the line of action to be adopted in compliance with the Constitution in order to respond to the event at Chernobyl: The Constitution demands maximum acceptable limits to be defined as low as possible. The author discusses the various dose estimations and the contradictions to be observed in this context. He states that the Chernobyl accident has done most harm to our legal system, as the basic right of freedom from injury has been ploughed under with the radioactivity that covered the soil after the Chernobyl accident. But, he says, a positive effect is that the idea of abandoning nuclear power as too dangerous a technology has gained more widespread acceptance. (HSCH).

  1. Environmental economics. Five basic key notions

    Laroui, F.; Benhaim, J.; Baron, R.; Helioui, K.; Glachant, M.; Corbaz, C.

    1994-12-01

    The greenhouse effect is a good example of the uncertainty inherent to environmental economics. Given the physical and factual uncertainties, the last thing we need is uncertainty in the words we use. Unfortunately, the semantics of environmental economics are sometimes too vague; and this vagueness can sometimes lead to conceptual errors. It is obvious that the concepts must be explicated and the relations which link them must be clarified if we are to use them without any risk of semantic Al confusion. This view, shared by all the participants, provided the theme of the SEO 1994 'Environmental Economics' seminar; its goal was to define and discuss some basic concepts. Jacques Benhaim gives a thorough discussion of the rate of discount. The rate of discount is an important item when it comes to a dynamic analysis in environmental economics. Richard Baron discusses modelling in its relation with the long-term assessment of greenhouse gases. In this context, he provides a 'catalogue raisonne' of the available models, then raises some interesting methodological issues involved in top-down modelling. His critique stresses the need of integrative models. Voluntary agreements constitute an alternative to taxation. Manhieu Glachant gives an overview of existing cases in 11 OECD countries; he then focuses on assessing their efficiency. Catherine Corbaz chose the much debated carbon tax. After giving some data on the greenhouse effect, she focuses on its economic aspects. After discussing uncertainty and technical progress, attention is paid to the reach of the tax: should it be global, or national and coordinated? Khalid Helioui was asked to elaborate on Catherine Corbaz by providing a more theoretical analysis of an optimal taxation on carbon. He proposes a two-goods dynamic model including the possibility of a backstop technique, which allows him to discuss an optimal carbon tax and to give a stimulating interpretation of the usage cost of the atmosphere

    The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters.

  3. RF Measurement Concepts

    Caspers, F

    2014-01-01

    For the characterization of components, systems and signals in the radiofrequency (RF) and microwave ranges, several dedicated instruments are in use. In this article the fundamentals of the RF signal techniques are discussed. The key element in these front ends is the Schottky diode which can be used either as a RF mixer or as a single sampler. The spectrum analyser has become an absolutely indispensable tool for RF signal analysis. Here the front end is the RF mixer as the RF section of modern spectrum analyses has a ra ther complex architecture. The reasons for this complexity and certain working principles as well as limitations are discussed. In addition, an overview of the development of scalar and vector signal analysers is given. For the determination of the noise temperature of a one-port and the noise figure of a two-port, basic concepts and relations are shown as well as a brief discussion of commonly used noise-measurement techniques. In a further part of this article the operating principles of n...

  9. Evolution of the Astronomy Concepts Along Basic Education Cycle. (Breton Title: Evolução dos Conceitos de Astronomia no Decorrer da Educação Básica.) La Evolución de los Conceptos de Astronomía Durante la Educación Básica

    Darroz, Luiz Marcelo; da Rosa, Cleci Werner; Becker da Rosa, Álvaro; Samudio Pèrez, Carlos Ariel

    2014-07-01

    Although astronomy is considered one of the older sciences of humanity and that the understanding of its concepts has brought tremendous advances to Science and therefore, to society, it is observed that a significant portion of people live outside of this kind of knowledge. According to the Parâmetros Curriculares Nacionais for basic education, it is the school responsibility the dissemination of scientifically correct concepts, including those related to astronomy. Concerning this issue, we present a survey of 140 students of ninth grade of elementary school and 120 third-grade high-school students from four schools in the region of Passo Fundo/RS. We sought to determine, through a questionnaire consisting of open and multiple choice questions, the knowledge of this group of students about the basic terms and astronomical phenomena, and also verify that the hit rate increases as they advance through the different and progressive grades of primary and secondary education. Overall, the results show that the teaching of astronomy in basic education is facing problems. Of the 20 issues investigated, in 17 the indicators are similar in the correct answers given by students for elementary and middle school, revealing that many misconceptions still remain along basic education. This demonstrates that such issues are not - or are rarely - covered during these two school levels. Thus, we conclude that the discussion of concepts related to astronomy should receive greater emphasis on approaching different subjects, requiring a national action in support of their teaching. It is believed that a national action should be supported by a triple pillar of collective actors: the scientific community, semi-professional astronomy community and the school community. Finally, this pillar would be the basis for future discussions related to the performance of these protagonists as a means to promote active changes in the curricular structure, providing, in more effective ways, the

  11. Concepts of magnetospheric convection

    Vasyliunas, V.M.

    1975-01-01

    Magnetospheric physics, which grew out of attempts to understand the space environment of the Earth, is becoming increasingly applicable to other systems in the Universe. Among the planets, in addition to the Earth, Jupiter, Mercury, Mars and (in a somewhat different way) Venus are now known to have magnetospheres. The magnetospheres of pulsars have been regarded as an essential part of the pulsar phenomenon. Other astrophysical systems, such as supernova remnant shells or magnetic stars and binary star systems, may be describable as magnetospheres. The major concepts of magnetospheric physics thus need to be formulated in a general way not restricted to the geophysical context in which they may have originated. Magnetospheric convection has been one of the most important and fruitful concepts in the study of the Earth's magnetosphere. This paper describes the basic theoretical notions of convection in a manner applicable to magnetospheres generally and discusses the relative importance of convective corotational motions, with particular reference to the comparison of the Earth and Jupiter.

    This second volume of the Berlin series presents the papers and discussion of the eleventh discussion meeting on energy law, for the first time held in Berlin, on May 12-13, 1987. The leading subject of the first conference day, namely electricity imports from France, has since then widely been discussed in the media or at other meetings, although the legal problems or obstacles revealed at this Berlin meeting are far from being solved. There is EdF's wish to export electricity to West Germany on the other hand, and there is the West German coal industry's scepticism on the other hand. Much is at stake for West Germany's national concept of enhanced use of coal for electricity generation, and the related system of subventions. Supply concepts and franchise charges, a standing topic of the power sector for quite a time now, have been discussed on the second conference day. The papers read there gave an account of the situation and also presented some new aspects.

The new electricity market in Ontario has introduced the energy trader, who enters into a contract with the consumer, based on the spot price set by the Independent Electricity Market Operator. Every contract has a fixed price payer as well as floating-price payers. If the floating price for a given amount of energy is higher than the fixed price, then the consumer gets the difference. Confusion, however, arises with the purchase of retail physical power in the market, particularly in deciding a fixed rate that the consumer will be paying. Different billing options were also discussed with emphasis on mid to large retail customers that have portfolios in the tens of MW and up to 100 MW or more. figs.

  18. Scientists Shaping the Discussion

    Abraham, J. A.; Weymann, R.; Mandia, S. A.; Ashley, M.

    2011-12-01

    Scientific studies which directly impact the larger society require an engagement between the scientists and the larger public. With respect to research on climate change, many third-party groups report on scientific findings and thereby serve as an intermediary between the scientist and the public. In many cases, the third-party reporting misinterprets the findings and conveys inaccurate information to the media and the public. To remedy this, many scientists are now taking a more active role in conveying their work directly to interested parties. In addition, some scientists are taking the further step of engaging with the general public to answer basic questions related to climate change - even on sub-topics which are unrelated to scientists' own research. Nevertheless, many scientists are reluctant to engage the general public or the media. The reasons for scientific reticence are varied but most commonly are related to fear of public engagement, concern about the time required to properly engage the public, or concerns about the impact to their professional reputations. However, for those scientists who are successful, these engagement activities provide many benefits. Scientists can increase the impact of their work, and they can help society make informed choices on significant issues, such as mitigating global warming. Here we provide some concrete steps that scientists can take to ensure that their public engagement is successful. These steps include: (1) cultivating relationships with reporters, (2) crafting clear, easy to understand messages that summarize their work, (3) relating science to everyday experiences, and (4) constructing arguments which appeal to a wide-ranging audience. With these steps, we show that scientists can efficiently deal with concerns that would otherwise inhibit their public engagement. Various resources will be provided that allow scientists to continue work on these key steps.

  19. Panel discussion: Nuclear cardiology

    Schwaiger, M.

    1991-01-01

    The panel discussion opened with a question concerning whether true quantification of myocardial sympathetic presynaptic function or receptor density can be obtained with currently available radiopharmaceuticals. What are the relative advantages of the two general approaches that have been proposed for quantification: (1) The assessment of tracer distribution volume in tissue following bolus injection and (2) quantification based on tracer displacement kinetics following administration of excess unlabeled tracer. It was pointed out that tracer kinetics for the delineation of presynaptic and postsynaptic binding sites by radiopharmaceuticals or radiolabeled receptor antagonists are rather complex, reflecting several physiologic processes that are difficult to separate. Several approaches were examined. The possibility of regional definition of receptor density by PET was questioned and it was noted that regions of interest can be applied to calculate regional receptor kinetics. However, due to the limited spatial resolution of PET, only average transmural values can be determined. The discussion then turned to the discrepancy between the known sparse parasympathetic innervation of the heart and the high density of muscarinic receptors observed with PET. Experiences with MIBG imaging were reported, including uptake in the transplanted heart and interaction of drugs with MIBG uptake

    The author deals with the experimental study of sorption, desorption and vertical migration of radionuclides in Sr-85 and Cs-137 in selected soil samples from around of NPP Bohunice and NPP Mochovce and other localities of the Slovakia. The influence of different materials [concurrent ions (K + , Ca 2+ , NH 4 + , pH), organic matter (peat) and zeolite, humidity] on kinetic of sorption and desorption of strontium and cesium as well as distribution coefficient (K D ) and transfer coefficients in followed samples of soils were followed. Obtained adsorption isotherm are presented and discussed. Using the Tessiere's sequential extraction analysis a gross variability in binding of radionuclides on soils was found. The obtained results were processed with the correlation analysis and the compartment model

  4. Basic Phage Mathematics.

    Abedon, Stephen T; Katsaounis, Tena I

    2018-01-01

    Basic mathematical descriptions are useful in phage ecology, applied phage ecology such as in the course of phage therapy, and also toward keeping track of expected phage-bacterial interactions as seen during laboratory manipulation of phages. The most basic mathematical descriptor of phages is their titer, that is, their concentration within stocks, experimental vessels, or other environments. Various phenomena can serve to modify phage titers, and indeed phage titers can vary as a function of how they are measured. An important aspect of how changes in titers can occur results from phage interactions with bacteria. These changes tend to vary in degree as a function of bacterial densities within environments, and particularly densities of those bacteria that are susceptible to or at least adsorbable by a given phage type. Using simple mathematical models one can describe phage-bacterial interactions that give rise particularly to phage adsorption events. With elaboration one can consider changes in both phage and bacterial densities as a function of both time and these interactions. In addition, phages along with their impact on bacteria can be considered as spatially constrained processes. In this chapter we consider the simpler of these concepts, providing in particular detailed verbal explanations toward facile mathematical insight. The primary goal is to stimulate a more informed use and manipulation of phages and phage populations within the laboratory as well as toward more effective phage application outside of the laboratory, such as during phage therapy. More generally, numerous issues and approaches to the quantification of phages are considered along with the quantification of individual, ecological, and applied properties of phages.

The topic that must covered such as atom and molecule, atomic structure, proton, isotope, half life, types of radiation and some basic formula such as formula for shielding, half life, half value layer, tenth value layer and more. All of this must be mastered by radiographer if they want to know more detail on this technique because this technique was a combination of theory and practical. Once they failed the theory they cannot go further on this technique. And to master this technique, once cannot depend on theory only. So, for this technique theory and practical must walk together.

  11. Fuel ethanol discussion paper

    1992-01-01

    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

  17. ¿Innovación o continuidad?: Dignidad humana y protección de la vida desde el momento de la concepción en la nueva Ley Fundamental húngara de 2011 // Innovation or continuity?: Human dignity and protection of life from conception in the new hungarian basic

    Juan José Ruiz Ruiz

    2014-11-01

    La controversia en torno al art. II no sólo ha estado centrada en el supuesto enfoque más restrictivo del nuevo texto constitucional hacia el aborto, sino que se ha extendido a la propia concepción de derecho de la dignidad humana, que para cierta doctrina ha recibido una configuración distinta a la concepción predominante en el derecho europeo. Under Article II of Hungarian Basic Law «Human dignity shall be inviolable. Every human being shall have the right to life and human dignity; embryonic and foetal life shall be subject to protection from the moment of conception». It is evident that, unlike the previous Constitution, the Basic Law expressly mentions the fetal and embryonic life, as also expressly stipulates that it shall be protected from the moment of conception. This new constitutional provision would be for some scholars, not strictly expanding the holders of the right to life, but at least extending the protective cloak of the Constitution to fetal and embryonic life from its beginning, which would effectively exclude outright the possibility of legal abortion at discretion of woman in any event, implying an absence of constitutional guarantee for other mother’s fundamental rights at stake. The controversy about art. II has been focused not only on the supposed more restrictive approach of the new constitution to abortion, but has reached to the very conception of the right to human dignity, that for some scholars has received a different configuration to the prevailing conception in European law.

  3. Search of unified theory of basic types of elementary particle interactions

    Anselm, A.

    1981-01-01

    Four types of forces are described (strong, weak, electromagnetic and gravitational) mediating the basic interactions of quarks and leptons, and attempts are reported of forming a unified theory of all basic interactions. The concepts are discussed, such as the theory symmetry (eg., invariance in relation to the Lorentz transformations) and isotopic symmetry (based on the interchangeability of particles in a given isotopic multiplet). Described are the gauge character of electromagnetic and gravitational interactions, the violation of the gauge symmetry and the mechanism of particle confinement. (H.S.)

  4. Basic training of nuclear power reactor personnel

    Palabrica, R.J.

    1981-01-01

    The basic training of nuclear power reactor personnel should be given very close attention since it constitutes the foundation of their knowledge of nuclear technology. Emphasis should be given on the thorough understanding of basic nuclear concepts in order to have reasonable assurance of successful assimilation by those personnel of more specialized and advanced concepts to which they will be later exposed. Basic training will also provide a means for screening to ensure that those will be sent for further spezialized training will perform well. Finally, it is during the basic training phase when nuclear reactor operators will start to acquire and develop attitudes regarding reactor operation and it is important that these be properly founded.

  10. Discussion

    Mittleman, M.H.

    1985-01-01

    The positive energy projection operators, just described by Prof. Sucher, convert the sick Hamiltonian, H/sub DC/, into a more robust one which can support bound states. They are however still a subject of some controversy. Prof. Grant pointed out that existing computer codes produce remarkable accuracy in numerical calculations which start from H/sub DC/ (with no projection operators) and so he questioned whether these operators were indeed necessary. In response, it was pointed out by several people in the audience that the codes implicitly limit the Dirac-Hartee-Fock wave functions to a normalizable sub-space and that this operation can be described as a projection operator which has the effect of eliminating the negative energy states which are not normalizable. This operation is however, not any of the three projection operators described by Sucher and so the question arises as to the sensitivity of the results (for the energy and wave functions) to the particular projection operators which are used. This appears to be an open question

  12. Sound Symbolism in Basic Vocabulary

    Søren Wichmann

    2010-04-01

    Full Text Available The relationship between meanings of words and their sound shapes is to a large extent arbitrary, but it is well known that languages exhibit sound symbolism effects violating arbitrariness. Evidence for sound symbolism is typically anecdotal, however. Here we present a systematic approach. Using a selection of basic vocabulary in nearly one half of the world’s languages we find commonalities among sound shapes for words referring to same concepts. These are interpreted as due to sound symbolism. Studying the effects of sound symbolism cross-linguistically is of key importance for the understanding of language evolution.

  16. A brief simulation intervention increasing basic science and clinical knowledge

    Maria L. Sheakley

    2016-04-01

    Full Text Available Background: The United States Medical Licensing Examination (USMLE is increasing clinical content on the Step 1 exam; thus, inclusion of clinical applications within the basic science curriculum is crucial. Including simulation activities during basic science years bridges the knowledge gap between basic science content and clinical application. Purpose: To evaluate the effects of a one-off, 1-hour cardiovascular simulation intervention on a summative assessment after adjusting for relevant demographic and academic predictors. Methods: This study was a non-randomized study using historical controls to evaluate curricular change. The control group received lecture (n l=515 and the intervention group received lecture plus a simulation exercise (nl+s=1,066. Assessment included summative exam questions (n=4 that were scored as pass/fail (≥75%. USMLE-style assessment questions were identical for both cohorts. Descriptive statistics for variables are presented and odds of passage calculated using logistic regression. Results: Undergraduate grade point ratio, MCAT-BS, MCAT-PS, age, attendance at an academic review program, and gender were significant predictors of summative exam passage. Students receiving the intervention were significantly more likely to pass the summative exam than students receiving lecture only (P=0.0003. Discussion: Simulation plus lecture increases short-term understanding as tested by a written exam. A longitudinal study is needed to assess the effect of a brief simulation intervention on long-term retention of clinical concepts in a basic science curriculum.
