In this study we report the discovery process which led to the development of antisense Phosphorodiamidate Morpholino Oligomers (PMOs AVI-6002 (composed of AVI-7357 and AVI-7539 and AVI-6003 (composed of AVI-7287 and AVI-7288 targeting Ebola virus and Marburg virus respectively. The discovery process involved identification of optimal transcript binding sites for PMO based RNA-therapeutics followed by screening for effective viral gene target in mouse and guinea pig models utilizing adapted viral isolates. An evolution of chemical modifications were tested, beginning with simple Phosphorodiamidate Morpholino Oligomers (PMO transitioning to cell penetrating peptide conjugated PMOs (PPMO and ending with PMOplus containing a limited number of positively charged linkages in the PMO structure. The initial lead compounds were combinations of two agents targeting separate genes. In the final analysis, a single agent for treatment of each virus was selected, AVI-7537 targeting the VP24 gene of Ebola virus and AVI-7288 targeting NP of Marburg virus, and are now progressing into late stage clinical development as the optimal therapeutic candidates.

    2014-01-01

    Citizen science projects store an enormous amount of information about species distribution, diversity and characteristics. Researchers are now beginning to make use of this rich collection of data. However, access to these databases is not always straightforward. Apart from the largest and international projects, citizen science repositories often lack specific Application Programming Interfaces (APIs) to connect them to the scientific environments. Thus, it is necessary to develop simple routines to allow researchers to take advantage of the information collected by smaller citizen science projects, for instance, programming specific packages to connect them to popular scientific environments (like R). Here, we present rAvis, an R-package to connect R-users with Proyecto AVIS (http://proyectoavis.com), a Spanish citizen science project with more than 82,000 bird observation records. We develop several functions to explore the database, to plot the geographic distribution of the species occurrences, and to generate personal queries to the database about species occurrences (number of individuals, distribution, etc.) and birdwatcher observations (number of species recorded by each collaborator, UTMs visited, etc.). This new R-package will allow scientists to access this database and to exploit the information generated by Spanish birdwatchers over the last 40 years.

    The AVI project was commissioned by the Minister of Civil Protection to the National Group for Prevention of Hydrogeologic Hazards to complete an inventory of areas historically affected by landslides and floods in Italy. More than 300 people, divided into 15 research teams and two support groups, worked for one year on the project. Twenty-two journals were systematically searched for the period 1918 1990, 350,000 newspaper issues were screened, and 39,953 articles were collected. About 150 experts on mass movement and floods were interviewed and 1482 published and unpublished technical and scientific reports were reviewed. The results of the AVI project, in spite of the limitations, represent the most comprehensive archiving of mass movement and floods ever prepared in Italy. The type and quality of the information collected and the methodologies and techniques used to make the inventory are discussed. Possible applications and future developments are also presented.

    While presenting two programmes which respectively concern the management of surroundings and resources, and the fields of energy and of sustainable development and land planning, and commenting their financial means, their objectives and performance indicators, this report shows that these programmes are facing insufficient grants. Then, it shows that the different public operators (research laboratories, centres and institutions, public agencies) are weakened by decreasing allocations. Three examples are then studied to show the difficulties of these institutions which have to perform fundamental missions with limited means: IFREMER (in the case of oyster control), INRA (for the development of the biotechnology sector) and IRSN (for the safety of nuclear waste storage)

    Evolution and development of the concept of partitioning of high-level liquid wastes (HLLW) in nuclear fuel reprocessing are reviewed historically from the early phase of separating useful radioisotopes from HLLW to the recent phase of eliminating hazardous nuclides such as transuranium elements for safe waste disposal. Since the criteria in determining the nuclides for elimination and the respective decontamination factors are important in the strategy of partitioning, current views on the criteria are summarized. As elimination of the transuranium is most significant in the partitioning, various methods available of separating them from fission products are evaluated. (auth.)

    Directory of Open Access Journals (Sweden)

    Bache-Wiig, Harald

    2011-03-01

    Full Text Available This essay is an investigation into the use of the fable genre in a Danish children’s magazine, Avis for Børn (Journal for the children, published in Copenhagen 1779‒1782 by the philanthropist and editor Emanuel Balling. The main purpose is to indicate that the classical, Aesopian genre to some extent was transformed and adapted to fit into the didactic and religious purpose dominating this journal. Some examples from the old lore are given to substantiate the assumption that the attitude of the fable mainly was a very pragmatic one, without the moral and religious orientation typical of the stories presented in Avis for Børn. In nature, Avis for Børn would admire the reign of a benevolent God, while in ancient fable nature is a place reigned by brutes and by arbitrary bestiality. Nevertheless, the journal chose to make some meaningful, yet strained use of the genre, without twisting the genre into pastoral sentimentality, a tendency that during the 19th century in children’s literature became predominant.

    Nuclear deterrence still represents an important part of French military budgets. However, its relative share is progressively reducing with the progress of the big programs implemented for its modernization. The 2005 finances law project rules out any risk of threat on these programs. This report presents, first, the schedule of the renewal of the strategic oceanic fleet (the M51 missile and the new generation of submarines) and the strategic air forces. Then, it comments the programs in progress at the direction of military applications of the atomic energy commission (CEA): a significant part of funds devoted to nuclear deterrence, the evolution of the simulation program, the delicate question of the financing of the dismantling of fissile material production facilities. Finally, it stresses of the research effort to sustain in order to stand the evolution of threats and to warrant the perenniality of deterrence: nuclear proliferation remains worrying and technologies linked with deterrence are changing rapidly, the need of a constant research effort in order to keep the competences up.

    1974-01-01

    This year the joint FAO/IAEA Division of Atomic Energy in Food and Agriculture celebrates its 10th anniversary. The aim of these two United Nations organizations is to ensure that the technical services of both FAO and IAEA are fully co-ordinated and their programmes are designed to assist developing Member States to apply isotopes and radiation techniques to the solution of food and agricultural problems. More precisely, the medium-term objectives of the Joint Division are to exploit the potential of nuclear techniques in research and development for increasing and stabilizing agricultural production, improving food quality, protecting agricultural products from spoilage and losses and minimizing pollution of food and the agricultural environment. This account of what radioisotopes can do for man in the agricultural field is therefore to a great extent a review of the activities of the Joint Division and a prediction of its future fields of emphasis, especially in the light of the present long-range and world-wide food crisis.

    2012-02-01

    The aim of this article is to provide an overview of existing studies on gay and lesbian parenthood and child development. Although 200,000 to 300,000 children could be concerned in 2010 in France, there is a lack of research on this issue in our country. Research among children raised by homosexual parents involves methodological issues, such as defining homosexual families, sampling cases and controls, and choosing structured or semi-structured evaluations. The fact that homosexual marriage, adoption and insemination are not presently legal in France could explain that only one study has been conducted in France in 2000 among 58 children raided by homosexual parents. This study concluded that these children did not show an increased rate of behavior or anxiety disorders. Concerns about lesbian parenting have focused on the absence of a father, the homosexual orientation of the mother, and their negative consequences on the development of the children. Research on parenting and child rearing has repeatedly compared lesbian and heterosexual families, and in the last 30 years a growing body of studies on lesbian parents and the development of their children has been published. Studies about child development, sexual orientation, gender identity, gender role behavior, emotional/behavioral development, social relationships and cognitive functioning showed no difference between children of lesbian mothers and those of heterosexual parents. Likewise, parental functioning, the mothers' psychological health and maternal skills were not significantly different among lesbian mothers than among heterosexual mothers. In studies concerning gay fathers, findings generally indicate no differences in sexual orientation, socialization, or psychological outcomes in children of gay fathers compared to children of heterosexual fathers. However, the first study on the adult attachment style dimensions of adult women who had gay or bisexual fathers suggested that they were

    Full Text Available Telepathology which is the diagnostic work of a pathologist at a distance has been developed to routine application within the last ten years. It can be classified in relation to application, technical solutions, or performance conditions. Diagnostic pathology performance distinguishes primary diagnosis (for example, frozen section statement from secondary diagnosis (for example, expert consultation and quality assurance (diagnostic accuracy, continuous education and training. Applications comprise (a frozen section service; (b expert consultations; (c remote control measurements; and (d education and training. The technical solutions distinguish active (remote control, live imaging systems from passive (conventional microscope handling, static imaging, and the performance systems with interactive (on‐line, live imaging use from those with passive (off‐line, static imaging practice. Intra‐operative frozen section service is mainly performed with remote control systems; whereas expert consultations and education/training are commonly based upon Internet connections with static imaging in an off‐line mode. The image quality, transfer rates, and screen resolution of active and passive telepathology systems are sufficient for an additional or primary judgment of histological slides and cytological smears. From the technical point of view, remote control telepathology requires a fast transfer and at least near on‐line judgement of images, i.e., image acquisition, transfer and presentation can be considered one performance function. Thus, image size, line transfer rate and screen resolution define the practicability of the system. In expert consultation, the pixel resolution of images and natural color presentation are the main factors for diagnostic support, whereas the line transfer rate is of minor importance. These conditions define the technical compartments, especially size and resolution of camera and screen. The performance of

    The paper presents the current trends of nuclear energy in Europe, the issue of radioactive waste management, the modern technical solutions for building new nuclear power plants and, also, the nuclear power long term prospects. The following trends and methods of reducing costs are addressed: - upgrading the availability of nuclear power units; since 1990 till now in Europe the availability factor has risen from 74 % to 84%; - extending the operation life of nuclear power plants from 30 - 40 years to 60 years; - stable reduction of the duration of annual planned outages necessary for maintenance and nuclear fuel re-loading; it is noteworthy the performance of Unit 2 Olkiluoto NPP, Finland, that was shutdown for annual outage and fuel re-loading for a 7 days only; - stable cuts of nuclear fuel cost by using advanced nuclear fuel and by increasing the fuel burnup; over the last years, nuclear fuel cost share in the operation costs has constantly decreased to values of about 0.5 USD cent/KWh e; - increase of the rated capacity of the existing in Europe nuclear power units, through upgrading programs that contribute to enhancing their efficiency. In the year 2002 Generation IV International Forum (GIF) finalized the technological strategy in the field, identifying the most promising nuclear power systems for which the research will continue. This strategy also identifies the main objectives that must by pursued within the research-development programs out of which one mentions the following: - identifying sustainable solution for generating electricity; - minimizing the radioactive waste and its management; - optimization of operation costs; - reducing the financial risk comparable to other energy solutions; - excellence in nuclear safety and reliability; - increasing resistance to proliferation; - ruling out the emergency solutions. Finally, the paper mentions the international engagement, representing a new approach in nuclear power, namely the transition to the use

    Present detectors for digital radiography are of two classes: real time detectors and storage (non real time) types. Present real time detectors consist of image intensifier tubes with an internal cesium iodide layer x-ray converter. Non real time detectors involve linear sweep arrays or storage detectors such as film. Future detectors discussed here can be of both types utilizing new technologies such as hydrogenated amorphous silicon photodiode arrays coupled to thin film transistor arrays. 17 refs., 10 figs

  12. Habenula circuit development: past, present and future

    Carlo Antonio Beretta

    2012-04-01

    Full Text Available The habenular neural circuit is attracting increasing attention from researchers in fields as diverse as neuroscience, medicine, behavior, development and evolution. Recent studies have revealed that this part of the limbic system in the dorsal diencephalon is involved in reward, addiction and other behaviors and its impairment is associated with various neurological conditions and diseases. Since the initial description of the Dorsal Diencephalic Conduction system (DDC with the habenulae in its center at the end of the 19th century, increasingly sophisticated techniques have resolved much of its anatomy and have shown that these pathways relay information from different parts of the forebrain to the tegmentum, midbrain and hindbrain. The first part of this review gives a brief historical overview on how the improving experimental approaches have allowed the stepwise uncovering of much of the architecture of the habenula circuit as we know it today. Our brain distributes tasks differentially between left and right and it has become a paradigm that this functional lateralization is a universal feature of vertebrates. Moreover, task dependent differential brain activities have been linked to anatomical differences across the left-right axis in humans. A good way to further explore this fundamental issue will be to study the functional consequences of subtle changes in neural network formation, which requires that we fully understand DDC system development. As the habenular circuit is evolutionarily highly conserved, researchers have the option to perform such difficult experiments in more experimentally amenable vertebrate systems. Indeed, research in the last decade has shown that the zebrafish is well suited for the study of DDC system development and the phenomenon of functional lateralization. We will critically discuss the advantages of the zebrafish model, available techniques and others that are needed to fully understand habenular circuit

Recent studies have revealed that this part of the limbic system in the dorsal diencephalon is involved in reward, addiction, and other behaviors and its impairment is associated with various neurological conditions and diseases. Since the initial description of the dorsal diencephalic conduction system (DDC) with the habenulae in its center at the end of the nineteenth century, increasingly sophisticated techniques have resolved much of its anatomy and have shown that these pathways relay information from different parts of the forebrain to the tegmentum, midbrain, and hindbrain. The first part of this review gives a brief historical overview on how the improving experimental approaches have allowed the stepwise uncovering much of the architecture of the habenula circuit as we know it today. Our brain distributes tasks differentially between left and right and it has become a paradigm that this functional lateralization is a universal feature of vertebrates. Moreover, task dependent differential brain activities have been linked to anatomical differences across the left-right axis in humans. A good way to further explore this fundamental issue will be to study the functional consequences of subtle changes in neural network formation, which requires that we fully understand DDC system development. As the habenular circuit is evolutionarily highly conserved, researchers have the option to perform such difficult experiments in more experimentally amenable vertebrate systems. Indeed, research in the last decade has shown that the zebrafish is well suited for the study of DDC system development and the phenomenon of functional lateralization. We will critically discuss the advantages of the zebrafish model, available techniques, and others that are needed to fully understand habenular circuit development.

    GANIL has been in operation since January 1983. During this period beams from Carbon to Xenon have been available continuously for physics. There is now a demand to extend the ion range up to uranium, and to increase the beam intensity above the present level of about 3 microamperes with light ions. The corresponding modifications of the machine have been studied and will be made in the near future. Progress in ion sources, beam diagnostics, computer control is reported. Speculative considerations on the distant future are discussed

    Full Text Available A Enterite Necrótica Aviária (ENA é uma enterotoxemia aguda que aparece subitamente e provoca morte rápida, afetando principalmente animais jovens. Embora seu impacto negativo na produção, devido ao aumento da conversão alimentar e da condenação de carcaças seja já conhecido, questões relacionadas à etiologia, à patogenia e ao controle desta importante enfermidade necessitam de maiores esclarecimentos. Nos últimos anos, o controle da ENA baseou-se na aplicação de antibióticos na ração animal, prática banida pelo mercado consumidor, que exigiu o desenvolvimento de novas estratégias de controle. Esta revisão aborda informações sobre a etiologia, a epizootiologia, a patogenia, o diagnóstico e o controle da doença, em especial a utilização de probióticos e vacinas como alternativas de controle da ENA.Avian Necrotic Enteritis is an acute enterotoxaemia that appears suddenly producing rapid deaths, affecting mainly young animals. Although its negative impact in poultry production is already known, factors related to etiology, pathogenesis and control of this important disease need better clarifications. For a long time its control was based on the use of antibiotics in poultry feed, whose the use was banned by several consumer markets, requiring the development of new control strategies. Informations on the etiology, epizootiology, pathogenesis, diagnosis and control are reviewed, emphasizing the role of probiotics and vaccines as control alternatives.

    The aim of this report is to present to the French deputies the advice of the commission of finances and economy about the law project relative to the change of status of the power and gas public utilities in the framework of the deregulation of European energy markets. This law changes the juridical status of the two state monopolies Electricite de France (EdF) and Gaz de France (GdF) into two anonymous companies and creates two additional companies for the management of the power and gas networks. It ensures also the transposition of the European directives from June 26, 2003 (2003/54/CE and 2003/55/CE). It contains some proper dispositions and modifies various existing French laws, in particular the law no. 46-628 from April 8, 1946 about the electricity and gas nationalization and the law no. 2000-108 from February 10, 2000 relative to the modernization and development of the electric public utility. The first part of the document reports on the general discussions and comments made by the commission about the law project while the second part concerns the detailed analysis of the articles 16 and 22 about the pension funds of EdF and GdF agents and the change of the status of both utilities. The amendments adopted by the commission for these articles conclude the report. (J.S.)

    At present, China's economic development faces energy challenge, and the appropriate solution of energy bottleneck is the key to healthy, rapid and sustainable development. China's gross amount of hydraulic resource ranks first in the world; however, because of low level of development, hydraulic resource has a broad development prospect. Now, China's hydropower development is in its peak period. By the end of 2004, the gross installed hydropower capacity of China broke through 100 million kW. From there, it has remained in the top slot worldwide. The vigorous development of hydropower is necessary because of the energy shortage and environmental pollution in China in order to attain sustainable development of China's economy. Abundant hydraulic resource, huge market demands, the strategy of western development and the favorable environment of economic development provide hydropower construction with unprecedented advantages and opportunities. Chins hydropower development aims at an installed hydropower capacity of up to 194 million kW by 2010, accounting for 23.1% of the gross installed power capacity and 35% of hydropower resource. Finally, we present the general condition of Three Gorges project as well as the new mode of hydropower development of Three Gorges Project Corporation, i.e., cascade development. (author)

  18. Influence of Background Genome on Enzymatic Characteristics of Yellow (Ay/-, Avy/-) Mice

    Wolff, George L.; Pitot, Henry C.

    1973-01-01

    Identification of the fundamental polypeptide difference between yellow (Ay/-, Avy/-) and non-yellow mice is important for biomedical research because of the influence of the yellow genotype on normal and neoplastic growth and obesity. The complexity of the "yellow mouse syndrome" makes attainment of this objective dependent on the separation of those pleiotropic enzyme differences which are secondary, and depend on the background genome, from those which are primary, and depend primarily on the agouti locus genotype.—Four of nine hepatic enzyme activities assayed simultaneously differed between eight-week-old yellow (Ay/-, Avy/-) and non-yellow (A/-, a/a) male inbred and F1 hybrid mice. Among these four, only cytoplasmic malic enzyme activity was elevated in all yellow mice, as compared with the non-yellow sibs, regardless of background genome. Glucokinase, serine dehydratase, and tyrosine α-ketoglutarate transaminase activities were also changed in yellow mice, but these alterations depended on the background genome.—The ratio of malic enzyme activity to citrate-cleavage enzyme activity, possibly related to the altered fat metabolism of yellow mice, was influenced by background genome as well as by the yellow genotype.——Significant deviations of enzyme activities from mid-parent values among F1 hybrids were associated with particular background genomes; the number of such deviations was larger among yellow mice than among non-yellows and this difference was greater among C3H F1 hybrids than among C57BL/6 F1 hybrids.

    To understand the present status and characteristics of Dendrobium officinale industry and to provide a rationale for the sustainable industrial development. Based on references and an on-site investigation of main Dendrobium officinale-producing enterprises and market, to analyze main existing problems and to propose suggestions for sustainable development. More than 10 provinces and regions are involved in the production around the center of Zhejiang and Yunnan provinces. These two provinces are different from each other in development pattern. Yunnan adopts a mode of companies minus farmer households but Zhejiang mainly employs a mode that a leading company establishes a production base with production, processing and marketing combined together. Zhejiang mode is characterized by high tech, high investment, high risk and high return. Existence of non-genuine species, stagnancy in development and application of varieties and techniques for quality control and a narrow channel for marketing are the key problems limiting sustainable development of the industry. The key to sustainable development of the industry is to establish a technological alliance to speed up development of common techniques and application of integrated innovations, to strengthen self-discipline and monitoring of production, and to expand sales market.

    1995-03-01

    Currently, medical curricula are structured according to disciplines, body systems, or clinical problems. Beginning in 1988, the faculty of the University of Calgary Faculty of Medicine (U of C) carefully evaluated the advantages and disadvantages of each of these models in seeking to revise their school's curriculum. However, all three models fell short of a curricular structure based on current knowledge and principles of adult learning, clinical problem solving, community demands, and curriculum management. By 1991, the U of C had formulated a strategic plan for a revised curriculum structure based on the way patients present to physicians, and implementation of this plan has begun. In creating the new curriculum, 120 clinical presentations (e.g., "loss of consciousness/syncope") were defined and each was assigned to an individual or small group of faculty for development based on faculty expertise and interest. Terminal objectives (i.e., "what to do") were defined for each presentation to describe the appropriate clinical behaviors of a graduating physician. Experts developed schemes that outlined how they differentiated one cause (i.e., disease category) from another. The underlying enabling objectives (i.e., knowledge, skills, and attitudes) for reaching the terminal objectives for each clinical presentation were assigned as departmental responsibilities. A new administrative structure evolved in which there is a partnership between a centralized multidisciplinary curriculum committee and the departments. This new competency-based, clinical presentation curriculum is expected to significantly enhance students' development of clinical problem-solving skills and affirms the premise that prudent, continuous updating is essential for improving the quality of medical education.

    Minghetti, E.

    1997-03-01

    The gas turbine is the most widely used prime mover all over the world for either power generation or mechanical drive applications. The above fact is due to the recent great improvements that have been done especially in terms of efficiency, availability and reliability. The future for gas turbine technological development looks very promising. In fact, although tremendous growth has already taken place, there is still the potential for dramatic improvements in performance. Compared with the competitive prime movers (conventional steam power plants and reciprocating piston engines) the gas turbine technology is younger and still following a strong growth curve. The coming decades will witness the continued increasing in turbine inlet temperature, the development of new materials and refrigeration systems and the commercialization of inter cooled system and steam cooled turbines. With the very soon introduction of the G and H technology, expected single and combined cycle efficiencies for heavy duty machines are respectively 40% and 60%, while maintaining 'single digit' levels in pollutant emissions. In this report are given wide information on gas turbine present technology (Thermodynamics, features, design, performances, emission control, applications) and are discussed the main lines for the future developments. Finally are presented the research and technological development activities on gas turbine of Italian National Agency for new Technology Energy and the Environment Energy Department

    The Japan Nuclear Ship Development Agency held the annual report meeting on April 8, 1981. The main contents were the plan of research and development of nuclear ships hereafter, the present state of the repair works for the nuclear ship ''Mutsu'', the progress of the selection of the new home port and others. In the last year, the function of research was given to the Agency by the revision of the related law. The full-scale repair works for Mutsu were started in August, 1980, and various equipments and shields in the containment vessel and the upper shields of the containment vessel have been removed. Subsequently, new shields are being installed. According to the report by the committee of nuclear ship research and development, the development of Mutsu, which is valuable as the experimental ship, is continued. Moreover, it is proposed to do the research and development of an improved marine nuclear plant for the purposes of securing the economic efficiency, the proving of the reliability of nuclear merchant ships, and the establishment of safety. As the home port for Mutsu, the new port will be constructed on the open sea side in Aomori Prefecture, and as a candidate, Sekine beach in Mutsu City was named. Till the completion of the new home port, Mutsu will be berthed in Ominato home port. The conditions for entering and berthing in Ominato port will be decided later. (Kako, I.)

    Abstract Disorders of sex development (DSD) present in different forms but, in most cases, with visible anomalies of the external genitalia. The diagnosis of DSD can have a vast impact on an individual; in addition to concerns about fertility and a higher risk of neoplasia, it may have severe...... psychosocial impact on the patient. This report presents two apparently healthy cases referred for operation because of unilateral undescended testis. In these two patients, uterine remnants were found during the operation, and underlying DSD conditions were unexpectedly diagnosed. One patient had a 45,X/46,XY...... mosaic karyotype, while the second patient had persistent müllerian duct syndrome, probably due to an anti-müllerian hormone receptor defect. Both conditions are extremely rare, but the findings reinforce that DSD should be considered in patients with cryptorchidism, especially if other clinical signs...

    In response to the progressive environmental deterioration, the Ecological Society of America has made a proposal, called "Sustainable Biosphere Initiative", to do research, teaching and decision making processes on biodiversity, global change and the effects of human activities on environment. The goal of appropriate environmental protection and welfare for mankind includes health and quality of life. Presently, Chile faces a number of environmental problems such as pollution, excessive urban growth, loss of agricultural areas, disposal of solid waste and species extinction. The lack of education and information in Chile, on these problems, is worrisome. The role of universities to overcome this deficit should be crucial in the future sustainable development of Chile.

    Stuart, Ann E

    2013-01-01

    This article describes a graduate class in presentation skills ("PClass") as a model for how a class with similar objectives, expectations and culture might be mounted for undergraduates. The required class is given for students in neuroscience and physiology programs at the University of North Carolina at Chapel Hill; I describe the class in the years I led it, from 2003-2012. The class structure centered on peer rehearsal, critiquing of PowerPoint, and chalk talks by the students; video-recording of student talks for later review by the student with the instructor; and presentation of polished talks in a formal setting. A different faculty visitor to the class each week gave the students a variety of perspectives. The students also gained insight into their own evolving skills by discussing the strengths and weaknesses of seminars given by visitors to the campus. A unique feature of the class was collaboration with a professional actor from the University's Department of Dramatic Arts, who helped the students develop techniques for keeping the attention of an audience, for speaking with confidence, and for controlling nervousness. The undergraduate campus would be expected to lend itself to this sort of interdisciplinary faculty cooperation. In addition, students worked on becoming adept at designing and presenting posters, introducing speakers graciously and taking charge of the speaker's question session, and speaking to a lay audience.

    1990-01-01

    The last year was the 50th year from the discovery of the nuclear fission of uranium in 1939. The utilization of atomic energy made the unfortunate start as atomic bombs, but after the 'Atoms for Peace' declaration of President Eisenhauer, it has become to contribute to the development of mankind as nuclear power generation and radiation utilization. In Japan, the Atomic Energy Act was instituted in 1955, and the utilization of atomic energy has been eagerly promoted. As to nuclear power generation, as of the end of June, 1989, 423 power plants were in operation in the world, which generated 333 million kW, equivalent to 17 % of the total generated electric power. The nuclear power plants under construction and at planning stage were 199 with 190 million kW capacity, in this way, the development is advanced actively. At present in Japan, 38 nuclear power plants are in operation, generating 29.46 million kW, which has reached 30 % of the total generated electric power. The social environment surrounding atomic energy and the basic way of thinking on atomic energy development are discussed. The demand and supply of electric power in 21st century and atomic energy, and the policy of electric power companies to cope with it are explained. (K.I.)

    2017-05-01

    Effective monitoring of structural and biological systems is an extremely important research area that enables technology development for future intelligent devices, platforms, and systems. This presentation provides an overview of research efforts funded by the Office of Naval Research (ONR) to establish structural health monitoring (SHM) methodologies in the human domain. Basic science efforts are needed to utilize SHM sensing, data analysis, modeling, and algorithms to obtain the relevant physiological and biological information for human-specific health and performance conditions. This overview of current research efforts is based on the Monitoring Osseointegrated Prosthesis (MOIP) program. MOIP develops implantable and intelligent prosthetics that are directly anchored to the bone of residual limbs. Through real-time monitoring, sensing, and responding to osseointegration of bones and implants as well as interface conditions and environment, our research program aims to obtain individualized actionable information for implant failure identification, load estimation, infection mitigation and treatment, as well as healing assessment. Looking ahead to achieve ultimate goals of SHM, we seek to expand our research areas to cover monitoring human, biological and engineered systems, as well as human-machine interfaces. Examples of such include 1) brainwave monitoring and neurological control, 2) detecting and evaluating brain injuries, 3) monitoring and maximizing human-technological object teaming, and 4) closed-loop setups in which actions can be triggered automatically based on sensors, actuators, and data signatures. Finally, some ongoing and future collaborations across different disciplines for the development of knowledge automation and intelligent systems will be discussed.

    1986-01-01

    In the JT-60 at JAERI, TiC-coated molybdenum and TiC-coated Inconel tiles are currently used as plasma interactive components. They have already been subjected to initial ohmic heating experiments and exhibited good adhesion characteristics under high heat flux conditions. The present article reviews a JAERI's coating development program for JT-60 experiments currently under way and for the next-step experiments. The program includes development and performance tests of the TiC-coated tiles, development of an in-situ coating technique for the repair of damaged surface of the tiles, and research on carbonization. Stress is laid on thermal shock and thermal fatigue tests of these coatings. In the thermal tests, adhesion between low-Z coatings and bulk materials have been investigated under high heat irradiation. TiC and TiN are used as coating material while Mo and Inconel 625 are employed as bulk material. Results are shown in this report concerning calculated temperature elavation of TiC/TiN/Mo due to hydrogen beam irradiation. As regards the irradiation time required for the melting of the substrate, experimental results mostly agree with calculations. Almost all coatings investigated are not exfoliated from the substrate until the melting of the substrate. (Nogami, K.)

    Sharma, Suhasini

    2017-01-01

    Pharmaceutical medical writing has grown significantly in India in the last couple of decades. It includes preparing regulatory, safety, and publication documents as well as educational and communication material related to health and health-care products. Medical writing requires medical understanding, knowledge of drug development and the regulatory and safety domains, understanding of research methodologies, and awareness of relevant regulations and guidelines. It also requires the ability to analyze, interpret, and present biomedical scientific data in the required format and good writing skills. Medical writing is the fourth most commonly outsourced clinical development activity, and its global demand has steadily increased due to rising cost pressures on the pharmaceutical industry. India has the unique advantages of a large workforce of science graduates and medical professionals trained in English and lower costs, which make it a suitable destination for outsourcing medical writing services. However, the current share of India in global medical writing business is very small. This industry in India faces some real challenges, such as the lack of depth and breadth in domain expertise, inadequate technical writing skills, high attrition rates, and paucity of standardized training programs as well as quality assessment tools. Focusing our time, attention, and resources to address these challenges will help the Indian medical writing industry gain its rightful share in the global medical writing business. PMID:28194338

  2. Present status of food irradiation and trend of its development

    1998-01-01

    Food irradiation has been studied, tested and evaluated intensively for more than 40 years, and at present, this technology has been taking-off for commercial use in many countries. Some 40 countries have approved its application for various food items on groups of food, and about 60 commercial irradiators have been providing irradiation service for food in 29 countries. In 1983, Codex General Standard for Irradiated Food with average irradiation dose limit not exceeding 10 kGy. The latest WHO press release on September 1997 stated that the maximum 10 kGy limit should not be there, since scientific evidences indicated that food irradiated even up to 75 kGy was safe to be consumed, as long as the sensory quality was acceptable and pathogenic organisms had been killed. The development of food irradiation in advanced countries, especially in USA is very significant lately, and hopefully this will be followed by other countries. In Indonesia, application of this technology has been approved since 1987, and six items or groups of food have been cleared for commercial irradiation. Further development and introduction of the technology are still needed to widen its application and to increase public awareness through harmonization of regulations among countries and dissemination of information. In addition, irradiation techniques for some specific purpose using either low dose, medium or high doses should be established to support effective, efficient and economical application. (author)

    2016-01-01

    Molecular markers, due to their stability, cost-effectiveness and ease of use provide an immensely popular tool for a variety of applications including genome mapping, gene tagging, genetic diversity diversity, phylogenetic analysis and forensic investigations. In the last three decades, a number of molecular marker techniques have been developed and exploited worldwide in different systems. However, only a handful of these techniques, namely RFLPs, RAPDs, AFLPs, ISSRs, SSRs and SNPs have received global acceptance. A recent revolution in DNA sequencing techniques has taken the discovery and application of molecular markers to high-throughput and ultrahigh-throughput levels. Although, the choice of marker will obviously depend on the targeted use, microsatellites, SNPs and genotyping by sequencing (GBS) largely fulfill most of the user requirements. Further, modern transcriptomic and functional markers will lead the ventures onto high-density genetic map construction, identification of QTLs, breeding and conservation strategies in times to come in combination with other high throughput techniques. This review presents an overview of different marker technologies and their variants with a comparative account of their characteristic features and applications.

    Full Text Available La temperatura es un factor importante en el momento de realizar una labor; sí la sensación térmica no es agradable, un trabajo sencillo puede transformase en un trabajo complicado, donde se puede exponer la integridad de la persona. En las aeronaves de entrenamiento los pilotos no son ajenos a los inconvenientes de la exposición a una temperatura elevada generada por radiación solar, equipos, entre otros. Al incluir un sistema de refrigeración a la cabina de entrenamiento de la aeronave ésta se ve afectada en características como equilibrio, mayor consumo de combustible, disminución de la eficiencia debido al aumento de peso. En este artículo, se proponen tres formas de disminuir la temperatura en la cabina del avión T-90, en las diferentes fases de vuelo, que consisten en implementar tomas y salidas de aire, utilizar una película térmica para la cabina y desarrollar un dispositivo que permita la circulación de aire en la fase previa al despegue.

    2015-02-01

    Freshwater comprises about a mere 2·5% of total global water, of which approximately two-thirds is locked into glaciers at the polar ice caps and on mountains. In conjunction with this, in many instances irrigation with freshwater causes an increase in soil salinity due to overirrigation of agricultural land, inefficient water use and poor drainage of unsuitable soils. The problem of salinity was recognized a long time ago and, due to the importance of irrigated agriculture, numerous efforts have been devoted towards improving crop species for better utilization of saline soils and water. Irrigating plants with saline water is a challenge for practitioners and researchers throughout the world. Recruiting wild halophytes with economic potential was suggested several decades ago as a way to reduce the damage caused by salinization of soil and water. A range of cultivation systems for the utilization of halophytes have been developed, for the production of biofuel, purification of saline effluent in constructed wetlands, landscaping, cultivation of gourmet vegetables, and more. This review critically analyses past and present halophyte-based production systems in the context of genetics, physiology, agrotechnical issues and product value. There are still difficulties that need to be overcome, such as direct germination in saline conditions or genotype selection. However, more and more research is being directed not only towards determining salt tolerance of halophytes, but also to the improvement of agricultural traits for long-term progress. © The Author 2014.

    Full Text Available The experiment was carried out with the objective of evaluating the effect on corn crop in crop-livestock integration system of fertilization with chicken litter in the pasture (winter and in the corn (summer, as alternative to organic production. The winter treatments consisted in the doses of 0 and 5 Mg ha-1 of chicken litter, with or without grazing of ovines and the summer treatments in the doses of 0, 1, 2, 4 and 8 Mg ha-1 of chicken litter in the corn. From the results obtained, it was checked that the grazing did not affect the grain yield of corn in summer. The use of chicken litter in winter presented significant effect on mass of one thousand grains of corn, evidencing residual effect of fertilization however, it was not sufficient to provide significant difference in corn yield. There was positive linear effect to number of grains per row and quadratic to corn yield by increase of chicken litter levels in summer. In areas without grazing the maximum corn yield would be obtained with application of 9 Mg ha-1 of chicken litter in summer, whereas this same yield would be obtained with 7 Mg ha-1 in grazed areas, representing an economy of 2 Mg ha-1 of chicken litter corresponding to 45 kg ha-1 of nitrogen. Thus, it was found technical viability by use of chicken litter in corn production in crop-livestock integration system. O experimento foi realizado com o objetivo de avaliar o efeito sobre a cultura do milho em sistema de integração lavoura-pecuária da adubação com cama de aviário na pastagem (inverno e no milho (verão, como alternativa para a produção orgânica.

    Ikeda, Hiroshi

    1984-11-01

    The development of FBRs in Japan now reached the stage to conclude on the development organization for a demonstration reactor positioning one step before a practical reactor. FBRs can be operated while converting uranium-238 existing in natural uranium by 99.3% to fissile plutonium-239, as the result, the nuclear fuel more than that consumed can be produced. However, there are various technical difficulties in FBRs, and the construction cost is estimated to be considerably higher as compared with that of LWRs. Also the plutonium obtained by reprocessing spent fuel is used for FBRs, accordingly, the development of FBRs is inseparable from the establishment of nuclear fuel cycle. In order to get rid of the burden of enormous development cost for FBRs, the trend of international joint development is conspicuous. The Superphenix with 1200 MWe output under construction centering around SERENA is expected to attain the criticality in the spring of 1985. For the development of a demonstration reactor, it is necessary to increase the role of private businesses, and the smooth transfer of know-how accumulated in Power Reactor and Nuclear Fuel Development Corp. to civilian side is an important problem.

  4. Reduced-activation steels: present status and future development

    2007-01-01

    Full text of publication follows: Reduced-activation steels for fusion reactor applications were developed in the 1980's to replace the commercial elevated- temperature steels first considered. In the United States, this involved replacing Sandvik HT9 and modified 9Cr-1Mo steels. Reduced-activation steels, which were developed for more rapid radioactivity decay following exposure in a fusion neutron environment, were patterned after the commercial steels they were to replace. The objective for the reduced-activation steels was that they have strengths (yield stress and ultimate tensile strength from room temperature to 600 deg. C) and impact toughness (measured in a Charpy test) comparable to or better than the steels they were replacing. That objective was achieved in reduced-activation steels developed in Japan, Europe, and the United States. Since the reduced-activation steels were developed in the 1980's, reactor designers have been interested designs for increased efficiency of future fusion plants. This means reactors will need to operate at higher temperatures-above 550 deg. C, which is the upper-temperature limit for the reduced-activation steels. Although the tensile and impact toughness of the reduced-activation steels exceed those of the commercial steels they were patterned after, their creep-rupture properties are inferior to some of the commercial steels they replaced. furthermore, they are much inferior to commercial steels that have been developed since the 1980's. Reasons for why the creep-rupture properties for the new commercial ferritic/martensitic steels are superior to the earlier commercial steels and the reduced-activation steels were examined. The reasons involve compositional changes that were made in the earlier commercial steels to give the new commercial steels their superior properties. Computational thermodynamics calculations were carried out to compare the expected equilibrium phases. It appears that similar changes in composition

    1987-01-01

    Energy resource is an essential prerequisite for realizing the strategic objectives of the national economic development in China. By the end of this century the objectives of the national economic development are as follows: the national annual gross value of industrial and agricultural output will be quadrupled as that in 1980; the annual average revenue per capita is expected to be 800-1000 U.S. dollars. For realizing these objectives, a significant discrepancy is anticipated between the energy demand and energy supplied. It is concluded, therefore, that the utilization of nuclear power should be regarded as one of the components constituting China's energy resources. From a longterm point of view, nuclear power will play an even more important role with each passing day. (author)

    2010-01-01

    It is widely acknowledged that Russia possesses enormous biomass resources (). Its vast areas devoted to agricultural production and plentiful timber resources suggest good prospects for the development of liquid biofuel production. However, no significant advances in this direction have been reported till now. None of the numerous investment projects announced at the heydays of biofuel excitement in Russia (2006-2008) are at the moment commercially operating. There are no specialised plants for the production of bioethanol and biodiesel in Russia. Little is known of the reasons for this discrepancy between biofuel potential and actual development. In investigating this discrepancy, this article analyses national developments and investigates local dynamics through a case-study in the Omsk region. It is found that the reasons for this discrepancy are not related to technological incapabilities, but are to be found in the low policy and institutional priority given to non-fossil fuel exploitation and lack of market opportunities. Sprouts of second generation liquid biofuel technologies can be identified within the state system, but it remains to be seen how strong and how long these will be supported by the Russian state.

  14. Present status of computational tools for maglev development

    1991-10-01

    High-speed vehicles that employ magnetic levitation (maglev) have received great attention worldwide as a means of relieving both highway and air-traffic congestion. At this time, Japan and Germany are leading the development of maglev. After fifteen years of inactivity that is attributed to technical policy decisions, the federal government of the United States has reconsidered the possibility of using maglev in the United States. The National Maglev Initiative (NMI) was established in May 1990 to assess the potential of maglev in the United States. One of the tasks of the NMI, which is also the objective of this report, is to determine the status of existing computer software that can be applied to maglev-related problems. The computational problems involved in maglev assessment, research, and development can be classified into two categories: electromagnetic and mechanical. Because most maglev problems are complicated and difficult to solve analytically, proper numerical methods are needed to find solutions. To determine the status of maglev-related software, developers and users of computer codes were surveyed. The results of the survey are described in this report. 25 refs.

  15. Present status and further objectives of SNR fuel element development

    International Nuclear Information System (INIS)

    Karsten, G.

    Within the scope of the fuel element development program for the fast breeder reactor SNR 300, 500 fuel pins have been irradiated since 1964, 250 of them in fast flux. Results indicate that the maximum nominal target burnup of 90.000 MWd/t of the SNR 300 Mk Ia possibly can be reached. The main problems, which arise from clad swelling and internal corrosion, can be met by special pretreatments of the austenitic stainless steel 1.4970 and a fuel stoichiometry of 1.97. Beyond this target burnup either material property improvements have to be made or burnup reductions have to be accepted. The remaining questions can be answered by the use of the SNR 300 as a test reactor. A further target is the development of a carbide fuel element, which should be very effective in a high power breeder reactor because of its low fissile inventory and high breeding gain. This development program will also be finalized in the SNR 300. (U.S.)

    Technical advances in the design of medical accelerators are making possible the exploration of new treatment techniques. Technology currently available to the radiation oncologist allows the use of internal and dynamic wedges. Multileaf collimators can be used for static treatment ports, and dynamic field shaping and beam modulation using multileaf collimators has been shown to be feasible. Computer interfaces are necessary to transfer the complex treatment sequences that are possible with these devices. Such network interfaces also provide for more efficient conventional treatments. New machines such as X-band linear accelerators and advanced proton accelerators are being developed for applications such as boron neutron capture therapy and proton conformal therapy.

  19. Present state of computer-aided diagnosis (CAD) development

    Topics of computer-aided detection (CAD) are reviewed. Commercially available, Food and Drug Administration (FDA)-approved CAD systems are for fields of breast cancer (mammography), chest (flat X-ray and CT imaging) and colon (polyp detection). In Japan, only mammography CAD is approved. Efficacy of CAD is controversial, for which reliable database is important, and its construction is under development in various medical fields. Digitalized image is now popularized, which conceivably leads to improve the cost-effectiveness of diagnosis with CAD. For incentive, approval for health insurance would be the case as seen in the increased CAD sale by R2 Technology Co., and MHLW actually assists facilities to introduce the reading-aid system of mammography by sharing a half of its cost. There are 2 big projects for CAD study supported by MECSST, which the author concerns. One is the development of diagnostic aid for the multi-dimensional medical images where the multi-organ, multi-disease CAD system is considered. The other involves the CAD in brain MRI, in breast US and in eyeground picture. It is not in so far future for patients and doctors to fully enjoy the benefit of CAD. (R.T.)

    2013-02-01

    Clinical interest in Vitamin D and its purported roles not only in calcium and bone metabolism but in several other medical conditions (diabetes, cardiovascular disease, multiple sclerosis, cancer, psychiatric disorders, neuro-muscular disease) has led to a surge in laboratory requests for 25 hydroxy vitamin D and 1,25 dihydroxy vitamin D measurement. Circulating 25 hydroxy vitamin D concentration is routinely used as the best indicator of vitamin D status, but measurement of other metabolites, especially the physiologically active 1,25 dihyroxy vitamin D, are of clinical value. Over the last 40 years the development of assays for vitamin D and its metabolites from early competitive binding assays through to immunoassay and liquid chromatography aligned to mass spectrometry have demonstrated various analytical challenges, the advantages and disadvantages of each method are constantly changing with new technological developments. Immunoassay remains the predominant mode of measurement for 25-hydroxy vitamin D although problems with equimolar recovery of the D2 and D3 metabolites remain an issue. Standardisation of all assays has been improved but not resolved with the currently available reference materials as evidenced by the international vitamin D external quality assurance scheme, DEQAS. The choice of method for each laboratory remains a balance mainly between turn around time, convenience, cost and the specificity and accuracy of the information obtained. With increasing discussion and clinical interest surrounding other vitamin D metabolites the vitamin D assay debate is set to continue.

  1. Present state of research and development of MHD power generation

    Ikeda, Shigeru

    1978-01-01

    MHD power generation can obtain electric energy directly from the heat energy of high speed plasma flow, and the power generating plant of 1 million kW can be realized by this method. When the MHD power generation method is combined before conventional thermal power generation method, the thermal efficiency can be raised to about 60% as compared with 38% in thermal power generation plants. The research and development of MHD power generation are in progress in USA and USSR. The research and development in Japan are in the second stage now after the first stage project for 10 years, and the Mark 7 generator with 100 kW electric output for 200 hr continuous operation is under construction. The MHD power generation is divided into three types according to the conductive fluids used, namely combustion type for thermal power generation, unequilibrated type and liquid metal type for nuclear power generation. The principle of MHD power generation and the constitution of the plant are explained. In Japan, the Mark 2 generator generated 1,180 kW for 1 min in 1971, and the Mark 3 generator generated 1.9 kW continuously for 110 hr in 1967. The MHD generator with superconducting magnet succeeded in 1969 to generate 25 kW for 6 min. The second stage project aimes at collecting design data and obtaining operational experience for the construction of 10 MW class pilot plant, and the Mark 7 and 8 generators are planned. (Kako, I.)

    The EC has had approximately 50% of its total energy demand supplied by imports from the exterior of the Community. Hence, it is getting important to develop oil-substituting renewable energy as well as to curtail the emission of carbon dioxide. In consideration of these situations, the results of investigation on the energy policy of the European Community are described. The policy comprises three courses: European Energy Charter, formation of an open European Community energy market, and environmental conservation. Particularly, concerning the reduction of carbon dioxide emission, the EC Council has decided to introduce carbon dioxide taxation so as to suppress the carbon dioxide emission in the year 2000 to the 1990 level. The arrangement for its introduction, however, encountered with difficulties because of the opposition of various countries other than the European Community and the industrial world of the European Community. Legislation of the investment promotion law for energy saving and the construction of infrastructure footing and an information network are ineffective due to the sluggish fuel price and economic recession. A plurality of EC member countries are advancing a comprehensive activity within the framework of the joint programs of research, development, and demonstration set for the renewable energy policy ensuring energy supply and environmental harmonization.

    Based on the Long-term Program for Development and Utilization of Nuclear Energy which was revised in 1987, the Japan Atomic Energy Research Institute (JAERI) has carried out the Research and Development (R and D) on the High Temperature Gas-cooled Reactors (HTGRs) in Japan. The JAERI obtained the installation permit of the High Temperature Engineering Test Reactor (HTTR) from the Government in November 1990 and started the construction of the HTTR facility in the Oarai Research Establishment in March 1991. The HTTR is a test reactor with thermal output of 30MW and outlet coolant temperature of 850degC at the rated operation and 950degC at the high temperature test operation, using the pin-in-block type fuel, and has capability to demonstrate nuclear process heat utilization. The reactor pressure vessel and intermediate heat exchanger were installed in the reactor containment vessel in 1994, and reactor internals were also installed in the reactor pressure vessel in 1995. The first criticality will be attained in December 1997. This report describes the design outline and construction progress of the HTTR, R and D of fuel, materials and components for the HTGR and high temperature nuclear heat application, and innovative and basic researches for high temperature technologies at the HTTR.

    Full Text Available Romania's participation in the implementation of EU regional policy means, first opportunity to benefit from a system of values that can be found between economic efficiency, environmental protection,ensuring minimum standards of existence, the definition of a "European lifestyle, urban values, qualified human resources. Moreover, European integration and openness to the EU internal market and the challenge involves increasing competitiveness, which can negatively affect the process of building an economy, like Romania. In this context, structural instruments are the most important resource that Romania will have to face the challenges of change and integration. However, regional development policy can not solely be the key to overall development of a state, especially in terms of its actual effects on growth are difficult to assess. A critical dimension of this is represented on the nature of economic and quality of other public policies that form the core of economic policy mix of a state: the legal protection of property rights and market economy, taxation, antitrust, etc.

    The study of phenomena related to the quantum behavior of macroscopic systems is subjected to new efforts both from theoretical and experimental point of view. The validity in fact of the description of macroscopic systems given by Quantum Mechanics is still under test, especially for what concerns the macrorealistic interpretation of the real world and the influence of dissipation on quantum systems. Many groups tried in the last few years to realize an experimental set-up to perform an MQC experiment; the intrinsic dissipation however limited the possibility to fulfill the experimental requirements. The technology for realizing high quality Josephson Junctions is now so advanced that in principle the tests proposed in the last ten years can hopefully performed with success. In the following we will present a short description of the basic principles for an MQC experiment, with special emphasis on the experiment planned by the Rome group. (author)

    For decades, the understanding of craniofacial development has been a central issue in odontology and developmental biology. As a consequence, a significant number of deformities are being studied for their variety of genotype and phenotype. Although there is little doubt about the essential roles of homeobox genes, transcription factors, and growth factors, we now know at least the fundamental strategy of craniofacial biology. The tooth as an organ performs a whole range of functions, each of which is truly indispensable for the maintenance of life. The possession of teeth is, therefore, obviously coupled with the complication of the natural structure of an individual organism. In the following, we shall focus on a brief history of tooth studies and some suggestions for obtaining a full understanding of teeth in the future. Copyright 2003 Wiley-Liss, Inc.

    2015-01-01

    Introduction Microdosing is an approach to early drug development where exploratory pharmacokinetic data are acquired in humans using inherently safe sub-pharmacologic doses of drug. The first publication of microdose data was 10 years ago and this review comprehensively explores the microdose concept from conception, over the past decade, up until the current date. Areas covered The authors define and distinguish the concept of microdosing from similar approaches. The authors review the ability of microdosing to provide exploratory pharmacokinetics (concentration-time data) but exclude microdosing using positron emission tomography. The article provides a comprehensive review of data within the peer-reviewed literature as well as the latest applications and a look into the future, towards where microdosing may be headed. Expert opinion Evidence so far suggests that microdosing may be a better predictive tool of human pharmacokinetics than alternative methods and combination with physiologically based modelling may lead to much more reliable predictions in the future. The concept has also been applied to drug-drug interactions, polymorphism and assessing drug concentrations over time at its site of action. Microdosing may yet have more to offer in unanticipated directions and provide benefits that have not been fully realised to date. PMID:23550938

    The IEA was established about five years ago in the OECD immediately after the oil crisis, and 20 countries have participated in it. Progress was observed in the control of the expansion of energy demand. The energy utilization in IEA member countries became efficient due to the contribution of new technologies, and owing to the improvement of productivity, the growth of energy consumption was less than 1% despite the GDP grew at the yearly rate of 2.5%. The expansion of the utilization of natural gas and coal is promising, but the projects of nuclear power generation are behind schedule. The short term prospect in petroleum market is discussed, and the price of crude oil tends to be stabilized. ''The prospect of energy in the world by 2000'' will be published by the IEA in the latter half of 1980. The scale of the development of nuclear power generation was reduced because the prediction of the rate of power generation growth was changed from 5.2% to 3.1%. The effect of new energy technologies on future energy market has been studied by the support of 15 countries, and it was recommended to give financial aid to heat pumps, coal liquefaction and the efficient recovery of oil and natural gas. Also the techniques for operating existing facilities under strict environment and safety regulations have been studied. (Kako, I.)

    Efforts are to be continuously devoted to establish and upgrade HTGR technology in the world. Japan Atomic Energy Research Institute (JAERI) has conducted the R and D of HTGRs since the 1960's in Japan, focusing on mainly the construction of High Temperature engineering Test Reactor (HTTR) which is an HTGR with a maximum helium gas temperature of 950 o C at the reactor outlet and HTGR utilization systems. The HTTR achieved first criticality on November 10, 1998 and will restart from January in 2001. In the R and D program of HTGR utilization systems, JAERI has conducted hydrogen production systems with HTGR to demonstrate the applicability of nuclear heat for extensive energy demands besides the electric power generation. JAERI has developed a hydrogen production system by steam reforming process of natural gas using nuclear heat supplied from the HTTR. Prior to the demonstration test of HTTR hydrogen production system, a 1/30-scale out-of-pile test facility is under construction for safety review and detailed design of the system. The out-of-pile test facility will be started in 2001 and will be continued about 4 years. The hydrogen permeation and corrosion tests have been carried out since 1997. Check and review for the demonstration program in the HTTR hydrogen production system will be made in 2001. Then the HTTR hydrogen production system is scheduled to be constructed from 2003 and demonstratively operated from around 2006. In parallel with the R and D of the HTTR hydrogen production system, hydrogen production method by thermochemical water splitting, so-called IS process, has been studied in JAERI. The IS process is placed as one of future candidates of the heat utilization systems of the HTTR following the steam reforming system. Continuous and stoichiometric production of hydrogen and oxygen for 48 hours was successfully achieved with a laboratory-scale apparatus mainly made of glass. Following this achievement, the study has been continued with a larger

    We translate Noël Bernard's discovery of orchid symbiotic germination discovered on Neottia nidus-avis, as published in the May 1899 issue of the Comptes rendus hebdomadaires des séances de l'Académie des sciences. In his note, Bernard (1874-1911) establishes the need for a fungus, which is also forming mycorrhizae in adults, for seeds germination. We provide illustrations reproduced from his later works, and summaries of the French text he cited. In our annotations, we show how early this discovery was done in Bernard's career, and insist on the scientific framework at the end of the nineteenth century, where orchid germination was mysterious and the need for vicinity of parents was not fully understood. We comment the text of Bernard on the basis of the most recent knowledge on Neottia nidus-avis and on orchid mycorrhizal fungi. Introducing his following papers, we finally discuss the emergence of the concept of peloton digestion, and how Bernard's work quickly paved the way to a general understanding of mycoheterotrophic germination in orchids and beyond.

    2010-07-01

    Full Text Available O crescimento da produção avícola provocado pela alta demanda do mercado acarreta um aumento da criação de aves em confinamento, o que resulta em um aumento da densidade das aves dentro do galpão. Em função disso, há um incremento da umidade da cama aviária, proveniente tanto das excretas das aves, como da água dos bebedouros, que favorece o crescimento de populações do coleóptero Alphitobius diaperinus, popularmente conhecido como cascudinho. O contato direto do inseto com a cama das aves, assim como a alimentação a partir de aves moribundas e mortas, faz do A. diaperinus um veiculador de diversos patógenos, sendo destacados bactérias, protozoários e vírus que causam imunossupressão nas aves. Além da relação com os patógenos, os cascudinhos podem provocar danos nas instalações avícolas, pois, na fase larval, escavam túneis no material isolante para empuparem e destroem a proteção de poliuretano usada para isolamento térmico dos galpões em países de clima frio, a qual precisa ser trocada a cada dois ou três anos. Outro fator prejudicial às aves é a substituição da ração balanceada por larvas e adultos do coleóptero, uma vez que afeta o ganho de peso, principalmente, das mais jovens. Frente ao exposto, a presença do cascudinho em instalações avícolas torna-se um problema, tanto sanitário, como financeiro. O controle do A. diaperinus é considerado difícil, e inseticidas químicos são comumente utilizados em aviários, mas apresentam desvantagens, pois deixam resíduos na carcaça, bem como no meio ambiente. A presença de alta quantidade de matéria orgânica nos aviários provoca a diminuição da efetividade dos inseticidas químicos. Vários estudos vêm sendo desenvolvidos na busca de alternativas, como, por exemplo, nematoides e fungos entomapatogênicos, mas até o momento não são produzidos em escala comercial.

    Williams, Randi

    This study was designed to explore elementary STEM professional development viewed from the presenters' and participants' perspectives. Numerous committees and educational organizations recommend investing in STEM professional development at the local, state, and national level. This investment must begin with research that inquires how STEM professional development is structured and what is needed for teacher and student success. Since there is a recent STEM education push in schools, elementary teachers need effective professional development in order to gain the necessary content, skills, confidence, and pedagogy required for those changing demands. This qualitative study embraced. Yin's case study methodology by observing short-duration STEM professional development for elementary teachers within a large metropolitan school system and an educational professional development agency. The study discussed the analysis and findings in the context of Bandura's sources of efficacy and Desimone's critical features of professional development. Data were gathered form professional development observations, presenter interviews, and participant interviews. The research questions for this study included: (a) based on Desimone's (2009) framework for professional development, what does content focused, active learning, coherence, duration, and collective participation look like in initial STEM professional development for elementary teachers? (b) are Bandura's (1997) four sources of self- efficacy: mastery experiences, vicarious experiences, social persuasion, and affective states evidenced within the short duration professional development? and (c) how do these two frameworks align between presenter and participant thoughts and actions? This study uncovered additional sources of efficacy are present in short-duration STEM professional development. These found sources include coherence, content, and active learning delivered in a definitive order. The findings of this study

    Oral case presentation is an essential skill in clinical practice that is decidedly varied and understudied in teaching curricula. We developed a curriculum to improve oral case presentation skills in medical students. As part of an internal medicine clerkship, students receive instruction in the elements of a good oral case presentation and then present a real-world case in front of a video camera. Each student self-evaluates his/her presentation and receives evaluations from his/her peers. We expect peer and self-evaluation to be meaningful tools for developing skills in oral presentation. We hope to not only improve the quality of oral case presentations by students but also to reduce the time burden on faculty.

    Full Text Available To identify risk factors and develop a prediction model for the development of profound and recurrent shock amongst children presenting with dengue shock syndrome (DSS.We analyzed data from a prospective cohort of children with DSS recruited at the Paediatric Intensive Care Unit of the Hospital for Tropical Disease in Ho Chi Minh City, Vietnam. The primary endpoint was "profound DSS", defined as ≥2 recurrent shock episodes (for subjects presenting in compensated shock, or ≥1 recurrent shock episodes (for subjects presenting initially with decompensated/hypotensive shock, and/or requirement for inotropic support. Recurrent shock was evaluated as a secondary endpoint. Risk factors were pre-defined clinical and laboratory variables collected at the time of presentation with shock. Prognostic model development was based on logistic regression and compared to several alternative approaches.The analysis population included 1207 children of whom 222 (18% progressed to "profound DSS" and 433 (36% had recurrent shock. Independent risk factors for both endpoints included younger age, earlier presentation, higher pulse rate, higher temperature, higher haematocrit and, for females, worse hemodynamic status at presentation. The final prognostic model for "profound DSS" showed acceptable discrimination (AUC=0.69 for internal validation and calibration and is presented as a simple score-chart.Several risk factors for development of profound or recurrent shock among children presenting with DSS were identified. The score-chart derived from the prognostic models should improve triage and management of children presenting with DSS in dengue-endemic areas.

    Self-presentation, a central element of young people's identity development, now extends from face-to-face contexts to social networking sites. Online self-presentation may change when youth transition to college, faced with the need to reclaim or redefine themselves in the new environment. Drawing on theories of self-presentation and self development, this study explores changes in youth's online self-presentation during their transition to a residential college. It also examines associations between online self-presentation and students' self-esteem and self-concept clarity. We surveyed 218 college freshmen (M age = 18.07; 64 % female, 79 % White) at the beginning and again at the end of their first semester. Freshmen's Facebook self-presentation became less restricted later in the semester. Broad, deep, positive, and authentic Facebook self-presentation was positively associated with perceived support from the audience, which contributed to higher self-esteem contemporaneously, though not longitudinally. Intentional Facebook self-presentation engaged students in self-reflection, which was related to lower self-concept clarity concurrently but higher self-esteem longitudinally. Findings clarified the paths from multifaceted online self-presentation to self development via interpersonal and intrapersonal processes during college transition.

Foram selecionados 32 artigos originais abordando os surtos recentes de infecção por um subtipo de vírus influenza A aviária, o H5N1, em criações de aves domésticas na Ásia, que resultaram em importantes prejuízos econômicos e repercussões em saúde pública, além de casos de infecção humana de alta letalidade. A maioria dos casos está associada com a exposição direta a aves infectadas ou superfícies contaminadas com excrementos dessas aves, porém foi confirmada a transmissão entre humanos. O período de incubação foi de dois a quatro dias. As manifestações clínicas variaram de infecção assintomática e doença leve do trato respiratório superior a pneumonia grave e falência múltipla de órgãos. A radiografia de tórax pode apresentar infiltrado intersticial bilateral, colapso lobar, consolidação focal e broncograma aéreo sem derrame pleural. A presença de linfopenia indica pior prognóstico. O tratamento de suporte parece ser o único tratamento aceitável. Os fatores de risco para mau prognóstico incluem idade avançada, demora na hospitalização, envolvimento do trato respiratório inferior, baixa contagem de leucócitos totais e linfopenia à admissão.

    The growing number of heart failure patients and the scarcity of organ donors account for the huge need for the development of mechanical circulatory systems, including ventricular assist devices (VADs) and artificial hearts, in China. Several research programmes on blood pumps have been under way for the last three decades. However, unlike in other countries, the development of VADs has been extremely slow, and no system is currently approved and available for clinical application. There are many reasons for this situation. This article provides an overview of the present development of experimental and clinical research on VADs in China. In addition, the challenges for the clinical development of mechanical circulatory support in China are discussed. © The Author 2014.

    A present Japanese national project for SMES development focuses on the development of cost reduction technologies for a small-scale SMES for power system control. Optimal SMES system concepts were developed for power system stabilization and for load fluctuation compensation or frequency regulation. Performance of the designed superconductors was analyzed through fabrication and tests of short sample superconductors. Then, two kinds of model coil systems were manufactured and tested for evaluation of the design concepts and cost reduction technology developments. A multi-pole solenoid coil set as a model coil system for load fluctuation compensation SMES was successfully tested, for example, in 10 000-pulse iterative charge-discharge operations. In addition, application of high-T C superconductors to SMES has been studied for further cost reduction, more reliable operation, etc

    Evidence is presented that predictive coding is fundamental to brain function and present in early infancy. Indeed, mismatch responses to unexpected auditory stimuli are among the earliest robust cortical event-related potential responses, and have been measured in young infants in response to many types of deviation, including in pitch, timing, and melodic pattern. Furthermore, mismatch responses change quickly with specific experience, suggesting that predictive coding reflects a powerful, early-developing learning mechanism. Copyright © 2011 Elsevier B.V.

    2015-10-01

    Full Text Available Development of the comprehensive care plan (CCP is a requirement for nursing homes participating in the federal Medicare and Medicaid programs, referred to as skilled nursing facilities. The plan must be developed within the context of the comprehensive interdisciplinary assessment framework—the Resident Assessment Instrument (RAI. Consistent compliance with this requirement has been difficult to achieve. To improve the quality of CCP development within this framework, an increased understanding of complex factors contributing to inconsistent compliance is required. In this commentary, we examine the history of the comprehensive care plan; its development within the RAI framework; linkages between the RAI and registered nurse staffing; empirical evidence of the CCP’s efficacy; and the limitations of extant standards of practices in CCP development. Because of the registered nurse’s educational preparation, professional practice standards, and licensure obligations, the essential contributions of professional nurses in CCP development are emphasized. Recommendations for evidence-based micro and macro level practice changes with the potential to improve the quality of CCP development and regulatory compliance are presented. Suggestions for future research are given.

    2013-10-01

    Permitting is a major component of the geothermal development process. Better coordination across government agencies could reduce uncertainty of the process and the actual time of permitting. This presentation highlights various forms of coordinating permit offices at the state and federal level in the western United States, discusses inefficiencies and mitigation techniques for permitting natural resource projects, analyzes whether various approaches are easily adaptable to utility-scale geothermal development, and addresses advantages and challenges for coordinating permit offices. Key successful strategies identified include: 1. Flexibility in implementing the approach (i.e. less statutory requirements for the approach); 2. Less dependence on a final environmental review for information sharing and permit coordination; 3. State and federal partnerships developed through memorandum of understanding to define roles and share data and/or developer information. A few of the most helpful techniques include: 1. A central point of contact for the developer to ask questions surrounding the project; 2. Pre-application meetings to assist the developer in identifying all of the permits, regulatory approvals, and associated information or data required; 3. A permit schedule or timeline to set expectations for the developer and agencies; 4. Consolidating the public notice, comment, and hearing period into fewer hearings held concurrently.

    46,XY pure gonadal dysgenesis (Swyer syndrome) is characterized by normal female genitalia at birth. It usually first becomes apparent in adolescence with delayed puberty and amenorrhea. Rarely, patients can present with spontaneous breast development and/or menstruation. A fifteen-year-old girl presented to our clinic with the complaint of primary amenorrhea. On physical examination, her external genitals were completely female. Breast development and pubic hair were compatible with Tanner stage V. Hormonal evaluation revealed a hypergonadotropic state despite a normal estrogen level. Chromosome analysis revealed a 46,XY karyotype. Pelvic ultrasonography showed small gonads and a normal sized uterus for age. SRY gene expression was confirmed by multiplex polymerase chain reaction. Direct sequencing on genomic DNA did not reveal a mutation in the SRY, SF1 and WT1 genes. After the diagnosis of Swyer syndrome was made, the patient started to have spontaneous menstrual cycles and therefore failed to attend her follow-up visits. After nine months, the patient underwent diagnostic laparoscopy. Frozen examination of multiple biopsies from gonad tissues revealed gonadoblastoma. With this report, we emphasize the importance of performing karyotype analysis, which is diagnostic for Swyer syndrome, in all cases with primary or secondary amenorrhea even in the presence of normal breast development. We also suggest that normal pubertal development in patients with Swyer syndrome may be associated with the presence of a hormonally active tumor.

    This paper reports that Japan lacks fossil fuel resources. Consequently, almost all fossil fuels are imported from abroad. Therefore, change in international affairs affects on Japan's politics and social life, as learned from experience of economic social life, as learned from experience of economic confusion caused by the oil crisis of 1973. For this reason, research and development (R and D) of alternative energy technologies was initiated in July 1974, which was promoted as one of national energy development programs called Sunshine Project. Presently, their technical developments are being continued to put practical use under this project. However, Japan's dependency of primary energy resources on oil is still high among major advanced countries and energy supply structure is significantly weak. Furthermore, from indetermination of the recent political condition in the Middle East, the importance of security against supply and demand of petroleum in middle and long term is generally recognized with the increasing cost of oil

    The aim was to make an inventory of the structures and buildings relating to the history of the use of hydropower along the River Kullaa, which runs into the River Kokemaeki, and to determine how they could be conserved and used in future. Their history and the 1990-91 status will serve as starting points for a master scheme, local plans and plans for individual rapids. The publication first gives a general account of the history of the use of hydropower and the development of hydropower plants. Information has been collected on the establishment and development of structures along the River Kullaa. The 1990-91 status has been established on the basis of inventories and measurements made in the field. The master scheme first examines the River Kullaa and its structures as a whole. Along the river there are three areas, whose development is discussed in the local plans. Finally, plans for the individual rapids are presented for three sites. (author)

    To improve the detection and quality of care of patients who attend the emergency department (ED) with confirmed or suspected domestic abuse (DA). A quality improvement report on the design, implementation and evaluation of a specialised service and structured training programme to detect and manage DA presentations within an emergency medicine department. The study was set in the ED at the Northern General Hospital, Sheffield, UK. Key measures for improvement included introducing a service within the ED to help staff manage DA and coordinate responses; improve staff confidence in detecting DA; develop a structured and consistent process by which to manage DA presentations. An Independent Domestic Violence Advocate service was introduced into the department in July 2011 through a multiagency agreement. A structured training and education programme was delivered to ED staff. A 'communications form' was developed for DA risk assessment and case management. The process was reviewed quarterly. One hundred and seventy-two referrals were made to the service (121 distinct clients) over a 12-month period. Staff reported greater confidence in detecting DA, and community partners highlighted the role the service had in improving DA detection and care quality within the city. Strong leadership and prioritising the issue within the department has facilitated the development of the process and contributed substantially to its success. Support from community partners has been invaluable in tailoring the service and education programme to the needs of staff and patients within the department.

    A high-sensitivity airborne gamma-ray spectrometric and magnetic survey system, using Na(Tl) detector volume of 50,000 cc for 4π and 4195 cc for 2π geometry applications, was designed, developed, and fabricated in 1978 and was flown for airborne surveys in various parts of India for over a decade. A compact complementary metal-oxide-semiconductor (CMOS) logic circuit based high-sensitivity airborne gamma-ray spectrometric and magnetic survey system with high noise-immunity using Na(Tl) detector volume of 50,000 cc for 4π and 12,500 cc for 2π geometry applications was developed and interfaced to an Inertial Navigation System in 1988. The system currently in use was flown extensively for airborne surveys in various parts of India for the Atomic Minerals Division, Oil and Natural Gas Commission, and Nuclear Power Corporation. The design aspects of the present system have been discussed. A microprocessor based DDAS and multichannel analysers, having on-line micro terminal and on-line corrections for Compton scatter, and background radiation to obtain corrected analog profiles for the spectrometric data, are currently under development. The design aspects of these units are described and evaluated for future high-sensitivity airborne gamma-ray spectrometric surveys with Nal(Tl) detector volumes similar to those of the present system.

    A {sup 129}Xe comagnetometer designed for the measurement of neutron electric dipole moment (nEDM) as precisely as 1 × 10{sup −27}e cm is presented. Highly nuclear spin polarized {sup 129}Xe are introduced into an EDM cell where the {sup 129}Xe spin precession is detected by means of the two-photon transition. The geometric phase effect (GPE) which generates the false nEDM was quantitatively discussed and the systematic error of nEDM from the GPE was estimated considering the buffer-gas suppression due to Xe atomic collisions. Research and development are in progress to construct the {sup 129}Xe comagnetometer with a field sensitivity of 0.3 fT. At present, about 70 % nuclear spin polarized {sup 129}Xe atoms have been obtained in a spin exchange opitial pumping cell, that are in the process of being transferred into the EDM cell via a cold trap.

    1990-01-01

    Following the Chernobyl reactor accident it was rapidly appreciated that, in addition to upgrading national radiological monitoring systems, action was required to facilitate international communication of the results obtained. The first such system was established by the Vienna Convention, drawn up under the auspices of the IAEA, which came into force in September, 1986. Subsequently the EC Council of Ministers decided in December, 1987, to set up a Community system which in many ways parallels that established by the Convention but differs significantly in certain aspects concerning its legal basis, initiation criteria, data provisions and communications requirements. The present paper describes the present status of the Community system and foreseeable future developments. It is a matter of policy that, to avoid unnecessary complications, this system should be, to the maximum extent practicable, fully compatible with that established by the Convention. Where appropriate, therefore, reference is also made to the latter system

    The Department of Energy's Vehicle Technology Program has launched the Computer-Aided Engineering for Automotive Batteries (CAEBAT) project to work with national labs, industry and software venders to develop sophisticated software. As coordinator, NREL has teamed with a number of companies to help improve and accelerate battery design and production. This presentation provides an overview of CAEBAT, including its predictive computer simulation of Li-ion batteries known as the Multi-Scale Multi-Dimensional (MSMD) model framework. MSMD's modular, flexible architecture connects the physics of battery charge/discharge processes, thermal control, safety and reliability in a computationally efficient manner. This allows independent development of submodels at the cell and pack levels.

    1996-01-01

    As for the FBR development in Japan, the Atomic Energy Commission revised the long term plan on the research, development and utilization of atomic energy in June, 1994, and under the basic policy that through the considerable period of using LWRs together, FBRs will be adopted as the main nuclear power plants in future, it was decided to establish FBR technology system so that the practical use of FBRs becomes feasible by about 2030 through two demonstration FBRs following the experimental FBR 'Joyo' and the prototype FBR 'Monju'. The Monju started power generation and transmission in August, 1995, but secondary sodium leak accident occurred in December, 1995, and at present it is stopped. The demonstration FBR No. 1 is a top entry type loop reactor, and the power output is about 660 MWe. The start of construction is scheduled at the beginning of 2000s. The research on the whole plant design is carried out as the research on the optimization of demonstration FBR plant for three years from fiscal year 1994. The design of the demonstration FBR No. 1, the research and development for it, the prospect of the practical use and the research and development for the practical use are reported. (K.I.)

  11. Nuclear power in the world. Its present status and development trends

    Bennett, L.

    1994-01-01

    A summary of the most important data about the nuclear power reactors in operation and under construction as of the end of 1993 is given: their capacity, share of world capacity, growth of nuclear electricity generation since 1970 and its distribution by country. Nuclear prospects in the medium (2015) and long term (2025) are connected with a broad range of factors: development of advanced reactors ensuring high level of safety, implementation of high level waste repositories, enhancing the public acceptance of nuclear power. The issue of the cost of electricity generation is also discussed. Nuclear capacity projections to 2015 by region are given with 'low' and 'high' estimates. The low case reflects the continuation of the present trend of stagnation in nuclear power development due to public opposition and low economic growth in OECD countries, uncertainties in Eastern Europe and lack of finding in developing countries. The high case reflects a moderate revival of nuclear power development in the light of a more comprehensive assessment of the macro-economic and environmental aspects of the different options available for electricity generation. 7 figs., 5 tabs.

  12. Present status of nuclear energy development and utilization in Japan 1994

    International Nuclear Information System (INIS)

    1994-03-01

    Today, world energy demands continue to increase, and over the middle and long-term, access to petroleum supplies may become difficult. At the same time, such serious environmental problems as global warming and acid rain, which are caused by the burning of fossil fuels, have drawn great public attention, and the international community has urged that solutions to them should be found. Because nuclear power offers an economically efficient, stable supply of energy whose production has little adverse effect on the environment, the world has recognized the necessity of continuing to develop and use it. The changing international political situation, however, has complicated nuclear energy matters. In Japan, particularly the collapse of the former Soviet Union and North Korea's announcement of its intention to withdraw from the Nuclear Weapons Non-Proliferation Treaty have been cause for concern. Under these circumstances, it has become increasingly important for Japan to secure stable sources of energy, since Japan is dependent on imports for its energy supply. To that end, Japan has steadily promoted the development and utilization of nuclear energy. In fiscal 1992, nuclear power accounted for 28.2 % of the total power generated by Japanese electric utilities. Japan has also worked steadily to develop a nuclear fuel cycle, which is important to the long-term stability of the energy supply. This publication describes the present status of nuclear energy development and utilization in Japan. (J.P.N.)

    The prevalence of phenotypic females with a 46,XY karyotype is low, thus current knowledge about age and clinical presentation at diagnosis is sparse even for the most frequent conditions, androgen insensitivity syndrome (AIS), and gonadal dysgenesis. To estimate incidence, prevalence, age at diagnosis, and clinical presentation at diagnosis in 46,XY females. A nationwide study covering all known females with a 46,XY karyotype in Denmark since 1960. The diagnosis of 46,XY disorder of sex development (DSD) was determined by medical record evaluation, data from the Danish National Patient Registry, and genetic testing, if available. A total of 166 females registered as 46,XY females in the Danish Cytogenetic Central Registry were identified. A total of 124 females were classified as having 46,XY DSD, 78 with AIS and 25 with gonadal dysgenesis, whereas the remaining subjects had a variety of different diagnoses. The prevalence of 46,XY females was 6.4 per 100 000 live born females, and for AIS and gonadal dysgenesis, it was 4.1 and 1.5 per 100 000, respectively. Median age at diagnosis was 7.5 years (95% confidence interval, 4.0-13.5; range, 0-34 y) in AIS and 17.0 years (95% confidence interval, 15.5-19.0; range, 0-28 y) in gonadal dysgenesis (P = .001). Clinical presentation was dependent on cause of DSD. The first estimate on prevalence of 46,XY females is 6.4 per 100 000 live born females. The presentation of AIS and gonadal dysgenesis is distinctly different, with AIS being diagnosed during childhood and gonadal dysgenesis during pubertal years. The presenting phenotype is dependent on the cause of 46,XY DSD.

    In Canada, there exists a mature research programme directed towards resolving the nuclear safety and licensing questions surrounding fission product iodine. This integrated programme has had the long term objectives of developing a mechanistic understanding of the important aspects of iodine behaviour in containment, and of producing a mechanistic computer code to predict iodine behaviour under conditions of interest. The research is funded by Canadian Utilities and AECL through the CANDU Owners Group. In parallel with the research, an applications effort is underway to put existing research results into service for the resolution of reactor safety and licensing issues, as well as to identify and develop solutions for more comprehensive problems, such as chemical mitigation strategies to control post-accident iodine release. The present paper describes (a) the present status and objectives of R and D on iodine, its recent evolution and its significant achievements, (b) the analytical tools that are emerging from this programme and (c) existing and planned future applications of the results of the iodine R and D programme. The author concludes with an assessment of the impact that the iodine programme has had on reactor safety and licensing questions in Canada

  15. The past, present, and future of health development campaigns: reflexivity and the critical-cultural approach.

    2008-07-01

    In contemporary society, health issues have gained increasing urgency in both political and academic spheres. Looking back at the failure of the modernist development initiatives, there is the need to realize that we live in a time of increasing sociopolitical complexity. The present moment is perhaps best understood in terms of a complex tension and linkage between the past and present, global and local, modern and postmodern. The critical-cultural approach to health campaigns is an approach that, through the reflexive interrogation of modernist assumptions underlying health communication campaigns, attempts to foreground the tensions inherent in the practice of health campaigns. This essay discusses the manner in which the critical-cultural approach interrogates modernist assumptions and provides an alternative paradigm for approaching the theory and practice of health campaigns by suggesting the necessity for reflexivity. Specifically, we discuss how the perspective interrogates the role of the media in development, the significance of culture, the locus of health responsibility, the impact of structural conditions, and the politics of knowledge, providing examples of campaigns that illustrate this reflexivity.

    2001-01-01

    Drigg is an operational facility for the near-surface disposal of solid low level radioactive waste (LLW). The disposal facility is located in Cumbria, north-west England, near the Sellafield nuclear site, and is owned and operated by British Nuclear Fuels plc (BNFL). Disposals at Drigg are carried out under the terms of an authorisation granted by the UK Environment Agency. Periodically the Drigg authorisation is subject to formal regulatory review. The current regulatory guidance, 'Disposal Facilities on Land for Low and Intermediate Level Radioactive Wastes: Guidance on Requirements for Authorisation' (the GRA) was published in 1997 and contains guidance on the principles and requirements against which the Environment Agency will consider applications for disposal authorisation. BNFL has undertaken to produce an updated Drigg postclosure safety case (PCSC) in September 2002 to support the next authorisation review. In preparation for this, BNFL published a 'Status Report on the Development of the 2002 Drigg PCSC' in March 2000. This paper discusses the main components of the Drigg PCSC and how they relate to each other. Central to the safety case will be a systematic, post-closure radiological safety assessment (PCRSA). However the main focus of this paper is on the other main components of the PCSC which are presented in conjunction with the PCRSA to make a complete and integrated safety case. In addition other confidence building activities which are key to developing and presenting the safety case are discussed, in particular communications with the stakeholders

    In a partnership last Spring with Arizona Public Service, the National Optical Astronomy Observatory (NOAO) created the 'Dark-Skies Energy Education Program: Energy Awareness for a Sustainable Future'. In this program, experienced science and technology education specialists from NOAO led 2 one-day professional development workshops for thirteen 6th grade teachers on dark skies and energy education. The workshops focused on three foundational, scaffolding activities and a final student research project. This in turn culminated in a Family Science Night where students presented their projects. In between these events, our NOAO team provided support for teachers through real-time video conferencing using FaceTime. In addition to the professional development, each teacher received a kit full of resource materials to perform the activities and research project. The kit was at no cost to the teacher, school, or district. Each kit contained the latest version of a tablet, which was used to facilitate communication and support for the teachers, as well as provide all the program's written teaching materials. The activities are in accordance with state, Common Core and Next Generation Science Standards. Our NOAO instructors gave firsthand experiences on how best to use these materials in a classroom or public setting. They also discussed opportunities on how they can incorporate, adapt and expand upon the activities and research projects in the classroom. Evaluation reports from the program's independent evaluator showed that the students enjoyed learning from the three foundational activities and research projects. The project presentations by the Yuma students were outstanding in their creativity, level of effort, and scientific accuracy. To summarize the evaluations, significant changes in knowledge and attitude were made with the teachers and students (from one-on-one interviews and surveys), but behavioral changes (albeit only over a semester) seemed minimal.

    As for other imaging sensor markets, whatever is the technology, the commercial spread of terahertz (THz) cameras has to fulfil simultaneously the criteria of high sensitivity and low cost and SWAP (size, weight and power). Monolithic silicon-based 2D sensors integrated in uncooled THz real-time cameras are good candidates to meet these requirements. Over the past decade, LETI has been studying and developing such arrays with two complimentary technological approaches, i.e. antenna-coupled silicon bolometers and CMOS Field Effect Transistors (FET), both being compatible to standard silicon microelectronics processes. LETI has leveraged its know-how in thermal infrared bolometer sensors in developing a proprietary architecture for THz sensing. High technological maturity has been achieved as illustrated by the demonstration of fast scanning of large field of view and the recent birth of a commercial camera. In the FET-based THz field, recent works have been focused on innovative CMOS read-out-integrated circuit designs. The studied architectures take advantage of the large pixel pitch to enhance the flexibility and the sensitivity: an embedded in-pixel configurable signal processing chain dramatically reduces the noise. Video sequences at 100 frames per second using our 31x31 pixels 2D Focal Plane Arrays (FPA) have been achieved. The authors describe the present status of these developments and perspectives of performance evolutions are discussed. Several experimental imaging tests are also presented in order to illustrate the capabilities of these arrays to address industrial applications such as non-destructive testing (NDT), security or quality control of food.

  19. Present state of research and development of atomic energy in five Asian countries

    1981-01-01

    The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries.

    Massive migration and increasing population in Malaysia has contributed to the increasing demand of quality and affordable housing. Over the past 50 years, the Malaysian housing industry has seen the growth of using conventional construction system such as reinforced concrete frame structures and bricks. The conventional system, as agreed by many researchers, causes delays and other disadvantages in some of the construction projects. Thus, the utilization of interlocking loadbearing hollow block (ILHB) system is needed to address these issues. This system has been identified as an alternative and sustainable building system for the construction industry in Malaysia which the PUTRA block system is the latest example of the ILHB developed. The system offers various advantages in terms of speed and cost in construction, strength, environmentally friendly and aesthetic qualities. Despite these advantages, this system has not been practically applied and develop in Malaysia. Therefore, this paper aims to review the past and present development of the interlocking loadbearing hollow block (ILHB) system that available locally and globally.

    Within the European Union, the two major breeding blanket concepts presently being developed are the helium cooled pebble bed (HCPB), and the helium cooled lithium lead (HCLL) blankets. For both concepts, different conceptual designs are being discussed with temperature windows in the range 250-550 deg. C for conservative approaches based on reduced activation ferritic-martensitic (RAFM) steels, and in the range 250-650 deg. C for more advanced versions, taking into account oxide dispersion strengthened (ODS) steels. As a final result of a systematic development of RAFM-steels in Europe, the 9% CrWVTa alloy EUROFER was specified and produced in an industrial scale with a variety of product forms. A large characterisation program is being performed including irradiation in materials test reactors between 60 and 450 deg. C ({<=}15 dpa), and in a fast breeder reactor at 330 deg. C up to 30 dpa. EUROFER is resistant to high temperature ageing, and the existing creep-rupture data ({approx}30,000 h, 450-600 deg. C) indicate long-term stability and predictability. The ODS variant of EUROFER shows superior tensile and creep properties compared to EUROFER. Applying a new production route has diminished the problem of lower ductility and inferior impact properties. A reliable joining technique for ODS and RAFM steels employing diffusion welding was successfully developed.

    2015-01-01

    Expansion of nuclear technologies and plans for new plants in Africa makes this an exciting time for more women to be involved in the nuclear sector and there are lots of opportunities across the nuclear value chain for women to be involved. In recent decades, more and more women are are now entering the nuclear field and many people are starting to recognise opportunities for women, since the role played by women in the nuclear field enhances the development goals for many countries. In developing countries and in Africa in particular, however, there is a greater need for awareness of women’s involvement in STEM fields in general, and to change prevailing attitudes about women’s participation in the nuclear science and technology in particular. This paper will look at various opportunities women have in the expanding nuclear sector in the continent, and how these opportunities can be utilised, not only for those in sciences but also in business disciplines. The approaches organizations and countries can take in broadening participation of the female gender in the nuclear development in Africa; will also be presented, as well as how to address the challenges faced by women in the dynamic nuclear field.

    The first nuclear power plant was nearing completion. However, due to change in political climate and support for the nuclear power program, this has been mothballed. There is a possibility for the introduction of nuclear power plant in the country's projected energy sources by the year 2020. The country has one research reactor, but at the present time it is undergoing repair and is not operational. The Philippine Nuclear Research Institute (PNRI), an Institute under the Department of Science and Technology (DOST), is the sole government agency mandated by the law to take charge of all matters pertaining to nuclear science and technology, and the regulation of nuclear energy. There is one another government agency, the Radiation Health Service (RHS) of the Department of Health, which is responsible for regulating the use and application of X-rays and non-ionizing radiation. The PNRI conducts national training courses in nuclear science and technology, and radiation protection to users of radioisotopes. Individual courses are outlined in the paper. Up to the present time, around 7,300 have participated in national training courses conducted by PNRI. Distributions of PNRI trainees are: 53 % for industrial, 12 % medical, 12 % for academe, and 23 % for others. Nuclear science and technology education in schools and universities are presented.

    Full Text Available After the triumph at the Battle of Salado (1340, Alfonso XI of Castile sent an embassy to Pope Benedict XII to inform him of victory. Naturally, the embassy was conceived as an act of propaganda. This episode was later recounted in the Crónica de Alfonso XI, the Poema de Alfonso Onceno and the Gran Crónica de Alfonso XI. The three works produced the ideological discourse that interested to the monarchy. The aim of this paper is to analyze the propaganda transmitted by these three texts. In the story of the embassy to Avignon, Alfonso XI is presented as the leader of Christendom against Islam.

    Be it proteins, new superconductors, polymers or ferro-magnetic compounds, fundamental research is laying foundations for possible technical applications as well as industrial exploitation. At the ESRF, industrial companies can be involved in two main ways, depending on the type of research they are interested in. The first concerns beam time allocation for non-proprietary and fully-published research, the procedure is the same as for public laboratories. The second concerns the proprietary research, for which a fee is charged and where results are kept confidential. The use of synchrotron radiation for the characterisation of materials is certain to play a crucial role in the development of new materials in the close future. It is a policy of the ESRF that European industry should share the benefit of its facilities. A survey of the today industrial activity at the ESRF and of its perspective in near future is presented.

    This agreement is above all an expression of the confidence in the future role of nuclear energy as an important energy source in electricity generation despite the present difficult situation in this market. This situation is today characterized by a saturation in many industrialized countries and by stretching or even postponing nuclear programs in many developing and newly industrialized countries under the impression of the Chernobyl accident and the related wave of anti-nuclear movements and due to the fact that the financing requirements of such nuclear power programs simply exceeded the available possibilities. However, a number of well-known facts justify the expectation that a revival of the nuclear market will take place in the foreseeable future. On the one hand it is evident that the electricity consumption will continue to increase significantly due to the population growth and the urgently needed improvement in the standard of living in many countries. On the other hand the extension of the use of fossil fuels increasingly raises concerns about the environmental consequences as well as about the future price development of such fuels. In addition it becomes more and more clear, that the dreams of phasing-out nuclear without several countries and political parties cannot be fulfilled. One of the important positive signs may be the justified hope of a revival of the nuclear market in the United States of America which in turn will certainly have a positive effect on the nuclear business in other areas. Thus we believe that the market is presently undergoing a difficult transition phase during which the suppliers have to prepare themselves for the challenge of the future. This assessment and the general trend of cooperation and concentration of the world's power plants industry was the basis for the cooperation between Fumarate and Siemens

    Full Text Available The relevance of this topic is associated with the diversity of causes behind crisis processes in economics and the individuality of each particular crisis. This necessitates classifying them in a detailed fashion. The present downturn is a manifestation of the cyclicity of the development of the global economic system amid present-day globalization and the established architecture of the institutional space. The formal (legislation, contractual rules, corporate norms, etc. and non-formal institutes (rules, customs, traditions, behavior as a whole, etc., undergoing changes in their structure and mechanisms, caused the emergence of financial innovations whose yield surpassed that of the real sector of the economy multifold. This facilitated the concentration of money in financial markets and transforming them into a thing-in-itself. The theory of economic cycles is one of the theories of economic dynamics which explain the movement of the national economy. While the theory of economic growth explores factors and conditions for growth as a long-term trend, the theory of cycles deals with causes behind fluctuations in economic activity through time. Results. In accordance with the aims of this study, the authors established that crises can have the following causes: objective, which are associated with the cyclical development of the system, modernization and restructuring needs, and the impact of external factors, and subjective, which reflect errors in management, shortcomings in the organization of production, and the imperfections of innovation and investment policy. A crisis can take its course manifestly and be easily detected or can be inconspicuous and take its course in a latent form. The most dangerous are crises that affect the system as a whole. In a situation of this kind, there forms a train of complex issues resolving which depends on the timeliness of detecting them and professionalism in managing the organization, municipal

    This invited keynote paper is the most recent among similar reviews published by the author, update to year 2011. In a format similar to that in past reviews, recent estimates and forecasts of the conventional fossil fuel resources and their reserve/production ratio, nuclear power, and renewable energy potential, and energy uses are surveyed. A brief discussion of the status, sustainability (economic, environmental and social impact), and prospects of fossil, nuclear and renewable energy use, and of power generation is presented. Beyond the general review, the paper focuses this year on some of the many important areas that deserve more attention: (1) the recently emerging game-changing developments of postponement of “peak oil”, nuclear power future following the disaster in Japan, and effects of the recent global economy downturn of global sustainability, (2) the potential and impacts of electric cars (3) the often neglected energy status and promising potential of Africa. Some ways to resolve the problem of the availability, cost, and sustainability of energy resources alongside the rapidly rising demand are discussed. The author’s view of the promising energy R and D areas, their potential, foreseen improvements and their time scale, and last year’s trends in government funding are presented.

    2017-11-01

    Full Text Available The development of molecularly imprinted polymers (MIPs to target polyphenols present in vegetable extracts was here addressed. Polydatin was selected as a template polyphenol due to its relatively high size and amphiphilic character. Different MIPs were synthesized to explore preferential interactions between the functional monomers and the template molecule. The effect of solvent polarity on the molecular imprinting efficiency, namely owing to hydrophobic interactions, was also assessed. Precipitation and suspension polymerization were examined as a possible way to change MIPs morphology and performance. Solid phase extraction and batch/continuous sorption processes were used to evaluate the polyphenols uptake/release in individual/competitive assays. Among the prepared MIPs, a suspension polymerization synthesized material, with 4-vinylpyridine as the functional monomer and water/methanol as solvent, showed a superior performance. The underlying cause of such a significant outcome is the likely surface imprinting process caused by the amphiphilic properties of polydatin. The uptake and subsequent selective release of polyphenols present in natural extracts was successfully demonstrated, considering a red wine solution as a case study. However, hydrophilic/hydrophobic interactions are inevitable (especially with complex natural extracts and the tuning of the polarity of the solvents is an important issue for the isolation of the different polyphenols.

    Full Text Available Although nature conservation is a well recognized topic at present, it is not a new phenomenon. Throughout history, there are numerous examples of efforts made by governments, rulers, or individual land owners to protect certain land areas that possessed unique natural values. While many of these areas were actually isolated as game preserves for hunting, they were also designed to conserve wildlife. The establishment of Yellowstone National Park in 1972 marks the modern concept of a national park as it was designed on a very large protected natural area. Presently, one of the most efficient ways for nature protection is “area conservation approach” that many organizations have been developing various systems and categories about. Unfortunately, in spite of such improvements and the extension of the protected area network, many of these areas are not properly protected and/or managed in some countries. This study summarizes the historical evolution of nature conservation systems and strategies in the world with the related international legislative aspects as well. As it stated in this paper, USA and Europa have a well known history on nature conservation and show great concern in respect to participating to the international convention and arrangements.

    India's Integrated Child Development Services (ICDS) was established in 33 projects in 1975 and is spread over 22 states; 67 additional projects were begun in 1977, and over the next 2 years; 100 additional projects were added. By 1991=92, coverage was almost 50% of the country with 2696 projects; the expectation is for 100% coverage by the year 2000. An infrastructure chart identifies the organization and integration between level and social welfare and health departments. Objectives are clearly identified and the departments functionally linked. Linkages are achieved by shared space and activities at various levels. Over the past 17 years, services have included minimum needs programs, integrated rural development and poverty alleviation, national health policy and education policy, universal immunization, and the development of women and children in rural areas. ICDS is sponsored 100% by the status and uniquely relies on the honorary anganwadi worker (AWW), who is a woman, recruited and chosen by the community, aged 21-45 years and middle-school educated. The AWW was responsibility for 2000 households or 1000 persons in rural areas and 700 persons in tribal areas. The AWW is crucial to the functioning of the program and receives an honorarium of Rs. 225-275/month for implementing the ICDs program; AWWs have helpers who are paid Rs. 110/month. Training over a 3-year period is conducted at the Bal Sevika Training Institute by the Indian Council of Child Welfare. Additional health personnel and their role and the number of persons/per area AWWS are responsible for, equipment, and functions are also described. The AWW is responsible for nonformal preschool education, organization of supplementary nutrition feeding, health and nutrition education of women and families, immunization of women and children, treatment and referral of common illnesses, growing monitoring, and community participation. Presently, there are 2506 central sector projects and 190 state sector

    2013-09-01

    Musculoskeletal diseases are one of the leading causes of disability worldwide. Among them, tendon and ligament injuries represent an important aspect to consider in both athletes and active working people. Tendon and ligament damage is an important cause of joint instability, and progresses into early onset of osteoarthritis, pain, disability and eventually the need for joint replacement surgery. The social and economical burden associated with these medical conditions presents a compelling argument for greater understanding and expanding research on this issue. The particular physiology of tendons and ligaments (avascular, hypocellular and overall structural mechanical features) makes it difficult for currently available treatments to reach a complete and long-term functional repair of the damaged tissue, especially when complete tear occurs. Despite the effort, the treatment modalities for tendon and ligament are suboptimal, which have led to the development of alternative therapies, such as the delivery of growth factors, development of engineered scaffolds or the application of stem cells, which have been approached in this review.

    1995-01-01

    The world population has exceeded 5 billion, today, and it is estimated to reach 10 billion in the middle of the twenty first century. Because of such rapid increase of population, the world energy consumption is estimated to increase tremendously. Furthermore, there are problems of limited energy resources from oil and coal down, how to respond to environment problems such as global warming, acid rain caused by fossil fuel burning, followed by carbon dioxide discharge. Under such circumstances of global scale problems, the nuclear power generation that is excellent in stable nature of supply, economic advantage, less effect to the environment, supplies about 20 % of the total power generation in the world. In our country, some 30 % of the total power generation relies on the nuclear power, as an indispensable power source. Radiation utilization, together with the nuclear power generation, is an important pillar of development and utilization of nuclear energy, and has penetrated deeply in the life of the people, in the fields of industry, agriculture, medicine and environmental protection, and it is contributing to realize affluent life to a great extent. Thus, expectations to the nuclear energy seem to grow larger and larger in future. The publication introduces present status and future potential of the development and utilization of the nuclear energy in Japan, including the basic idea and concrete plans shown in the Long-Term Program.

    Japan Atomic Energy Agency (JAEA) has initiated R and D project on nuclear forensics technology such as analytical technologies towards the establishment of nuclear forensics capabilities in Japan. National Nuclear Forensics Library (NNFL) is one of the fundamental nuclear forensics capabilities and a prototype NNFL has been developed as one topic of the R and D project at JAEA. Main objective of NNFL is to determine whether a seized nuclear or other radioactive material from nuclear security event (e.g. illicit trafficking) is originated from one's country or not. Analytical data of the seized material are compared with the existing materials populated in a NNFL, and its attributions such as origin and history will be identified. This paper describes the current status and future plan on the development of prototype NNFL. The outline and the results of the participation in an international table top exercise on NNFL named 'Galaxy Serpent' are also reported in the present paper. (author)

    In the last two decades the definition of the term "virtual museum" changed due to rapid technological developments. Using today's available 3D technologies a virtual museum is no longer just a presentation of collections on the Internet or a virtual tour of an exhibition using panoramic photography. On one hand, a virtual museum should enhance a museum visitor's experience by providing access to additional materials for review and knowledge deepening either before or after the real visit. On the other hand, a virtual museum should also be used as teaching material in the context of museum education. The laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has developed a virtual museum (VM) of the museum "Alt-Segeberger Bürgerhaus", a historic town house. The VM offers two options for visitors wishing to explore the museum without travelling to the city of Bad Segeberg, Schleswig-Holstein, Germany. Option a, an interactive computer-based, tour for visitors to explore the exhibition and to collect information of interest or option b, to immerse into virtual reality in 3D with the HTC Vive Virtual Reality System.

    The Nuclear Training Center (NTC) of KAERI (Korea Atomic Energy Research Institute) began training technical personnel in the field of radioisotope utilization and radiation protection during the 1960's. During the first stage of the nation's nuclear power project in the 1970's, the main effort of the Center focused on training those in nuclear power and nuclear engineering. During a stage of increased technical self-reliance in the 1980's, the Center extended its training role to implement more specific training courses on nuclear power and safety fields. Since 1983, the Center has been empowered at the request of government to provide retraining courses for nuclear-related license holders and qualified engineers. The Center has offered IAEA regional training course annually for Asia and Pacific region member states since 1988. Since 1967, the total number of trainees is up to 27,777 as of the end of 1998. KEPCO (Korea Electric Power Corporation) started Nuclear Power Education Center (NPEC) in 1990. The outlines of KEPCO's in-house training programs are presented in the report. The reactor operators, and the persons engaged in nuclear fuel materials, radioisotope or radiation generating devices need particular licenses in accordance with Korean Atomic Energy Laws and Regulation. NTC/KAERI and NPEC/KEPCO should report annual retraining programs for licensed personnel to Ministry Of Science and Technology (MOST) every year. The outlines of projects, which are directly related to human resources development in nuclear field in Korea, are described in the paper. The International Atomic Energy Agency (IAEA) has made efforts to provide training programs for technical personnel of developing countries for the peaceful uses of nuclear energy.

  1. Presenting quantitative information about decision outcomes: a risk communication primer for patient decision aid developers

    Science.gov (United States)

    2013-01-01

    Background Making evidence-based decisions often requires comparison of two or more options. Research-based evidence may exist which quantifies how likely the outcomes are for each option. Understanding these numeric estimates improves patients’ risk perception and leads to better informed decision making. This paper summarises current “best practices” in communication of evidence-based numeric outcomes for developers of patient decision aids (PtDAs) and other health communication tools. Method An expert consensus group of fourteen researchers from North America, Europe, and Australasia identified eleven main issues in risk communication. Two experts for each issue wrote a “state of the art” summary of best evidence, drawing on the PtDA, health, psychological, and broader scientific literature. In addition, commonly used terms were defined and a set of guiding principles and key messages derived from the results. Results The eleven key components of risk communication were: 1) Presenting the chance an event will occur; 2) Presenting changes in numeric outcomes; 3) Outcome estimates for test and screening decisions; 4) Numeric estimates in context and with evaluative labels; 5) Conveying uncertainty; 6) Visual formats; 7) Tailoring estimates; 8) Formats for understanding outcomes over time; 9) Narrative methods for conveying the chance of an event; 10) Important skills for understanding numerical estimates; and 11) Interactive web-based formats. Guiding principles from the evidence summaries advise that risk communication formats should reflect the task required of the user, should always define a relevant reference class (i.e., denominator) over time, should aim to use a consistent format throughout documents, should avoid “1 in x” formats and variable denominators, consider the magnitude of numbers used and the possibility of format bias, and should take into account the numeracy and graph literacy of the audience.

    Molecular markers associated with gene coding regions are useful tools for bridging functional and structural genomics. Due to their high abundance in plant genomes, single nucleotide polymorphisms (SNPs) are present within virtually all genomic regions, including most coding sequences. The objective of this study was to develop a set of SNPs for the apple by taking advantage of the wealth of genomics resources available for the apple, including a large collection of expressed sequenced tags (ESTs). Using bioinformatics tools, a search for SNPs within an EST database of approximately 350,000 sequences developed from a variety of apple accessions was conducted. This resulted in the identification of a total of 71,482 putative SNPs. As the apple genome is reported to be an ancient polyploid, attempts were made to verify whether those SNPs detected in silico were attributable either to allelic polymorphisms or to gene duplication or paralogous or homeologous sequence variations. To this end, a set of 464 PCR primer pairs was designed, PCR was amplified using two subsets of plants, and the PCR products were sequenced. The SNPs retrieved from these sequences were then mapped onto apple genetic maps, including a newly constructed map of a Royal Gala x A689-24 cross and a Malling 9 x Robusta 5, map using a bin mapping strategy. The SNP genotyping was performed using the high-resolution melting (HRM) technique. A total of 93 new markers containing 210 coding SNPs were successfully mapped. This new set of SNP markers for the apple offers new opportunities for understanding the genetic control of important horticultural traits using quantitative trait loci (QTL) or linkage disequilibrium analysis. These also serve as useful markers for aligning physical and genetic maps, and as potential transferable markers across the Rosaceae family.

    The Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) mission is joint mission between Europe and Japan for the launch year of 2018. Mission objective is to improve scientific understanding of cloud-aerosol-radiation interactions that is one of the biggest uncertain factors for numerical climate and weather predictions. The EarthCARE spacecraft equips four instruments such as an ultra violet lidar (ATLID), a cloud profiling radar (CPR), a broadband radiometer (BBR), and a multi-spectral imager (MSI) and perform complete synergy observation to observe aerosols, clouds and their interactions simultaneously from the orbit. Japan Aerospace Exploration Agency (JAXA) is responsible for development of the CPR in this EarthCARE mission and the CPR will be the first space-borne W-band Doppler radar. The CPR is defined with minimum radar sensitivity of -35dBz (6dB better than current space-borne cloud radar, i.e. CloudSat, NASA), radiometric accuracy of 2.7 dB, and Doppler velocity measurement accuracy of less than 1.3 m/s. These specifications require highly accurate pointing technique in orbit and high power source with large antenna dish. JAXA and National Institute of Information and Communications Technology (NICT) have been jointly developed this CPR to meet these strict requirements so far and then achieved the development such as new CFRP flex-core structure, long life extended interaction klystron, low loss quasi optical feed technique, and so on. Through these development successes, CPR development phase has been progressed to critical design phase. In addition, new ground calibration technique is also being progressed for launch of EarthCARE/CPR. The unique feature of EarthCARE CPR is vertical Doppler velocity measurement capability. Vertical Doppler velocity measurement is very attractive function from the science point of view, because vertical motions of cloud particles are related with cloud microphysics and dynamics. However, from engineering point of

    We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey. Nearly 90% of participating students felt they had learned a great deal in the areas of formulating a hypothesis, experimental design, and collecting and analyzing data; 72% of students felt this project had improved their scientific writing skills. In a separate survey, 84% of students who responded felt that peer review was valuable in improving their final poster submission. We designed this inquiry-based poster project to improve student scientific communication skills. This exercise is appropriate for any microbiology laboratory course whose learning outcomes include the development of scientific inquiry and literacy. PMID:29904518

    Full Text Available In comparing to both ores and energetical minerals there are occurences of extremly rich non-methallics minerals on the Slovak territory. These minerals represent very large-scale sortiment with a considerable amount of verified reserves. Reserves of magnesite, salt rock, dolomite, limestone, talc, bentonite, clays and another construction minerals present many possibilities of their industrial utilization. A specific case is the mining of dimension stones such as stable ingeneous,sedimentary and metamorphic rocks that are mined in the open-pit blocks. Applicable to the production of both ingeneous stone and gross stone [3].The open-pit mining and dimension stone processing by the both above mentioned stone productions forms are focused mainly to the external and internal building industry. Despite of the fact that the natural reserves of dimension stone are limited at the Slovak territory, being distributed at large numbers of open-pits mines, from the point of view of the next development of the dimension stone industry its technical and economic vitalitycan be expected. The paper deals with both the technological and ecological mining problems of dimension stone and shows the possibilities how to improve both the works productivity and quality of products including the ecological impacts by the dimension stone mining.

  7. Markets, Availability, Notice, and Technical Performance of Terahertz Systems: Historic Development, Present, and Trends

    2015-03-01

    Although a lot of work has already been done under the older terms "far infrared" or "sub-millimeter waves", the term "terahertz" stands for a novel technique offering many potential applications. The latter term also represents a new generation of systems with the opportunity for coherent, time-resolved detection. In addition to the well-known technical opportunities, an historical examination of Internet usage, as well as the number of publications and patent applications, confirms ongoing interest in this technique. These activities' annual growth rate is between 9 % and 21 %. The geographical distribution shows the center of terahertz activities. A shift from the scientific to more application-oriented research can be observed. We present a survey among worldwide terahertz suppliers with special focus on the European region and the use of terahertz systems in the field of measurement and analytical applications. This reveals the current state of terahertz systems' commercial and geographical availability as well as their costs, target markets, and technical performance. Component cost distribution using the example of an optical pulsed time-domain terahertz system gives an impression of the prevailing cost structure. The predication regarding prospective market development, decreasing system costs and higher availability shows a convenient situation for potential users and interested customers. The causes are primarily increased competition and larger quantities in the future.

    Evidence-based healthcare (EBHC) emphasizes the integration of the best research evidence with patient values, specialist suggestions, and clinical circumstances during the process of clinical decision-making. EBHC is a recognized core competency in modern healthcare. Nursing is a professional discipline of empirical science that thrives in an environment marked by advances in knowledge and technology in medicine as well as in nursing. Clinical nurses must elevate their skills and professional qualifications, provide efficient and quality health services, and promote their proficiency in EBHC. The Institute of Medicine in the United States indicates that evidence-based research results often fail to disseminate efficiently to clinical decision makers. This problem highlights the importance of better promoting the evidence-based healthcare fundamentals and competencies to frontline clinical nurses. This article describes the historical background and present development of evidence-based healthcare from the perspective of modern clinical nursing in light of the importance of evidence-based healthcare in clinical nursing; describes the factors associated with evidence-based healthcare promotion; and suggests strategies and policies that may improve the promotion and application of EBHC in clinical settings. The authors hope that this paper provides a reference for efforts to improve clinical nursing in the realms of EBHC training, promotion, and application.

    We will present our last development of GMR-based magnetic sensors devoted to sensing application for non-destructive control application. In these first realizations, we have chosen a so-called shape anisotropy - exchange biased strategy to fulfill the field-sensing criteria in the μT range in devices made of micronic single elements. Our devices realized by optical lithography, and whose typical sizes range from 150 μm x 150 μm to 500 μm x 500 μm elements, are made of trilayers GMR-based technology and consist of several circuitries of GMR elements of different lengths, widths and gaps. To obtain a full sensing linearity and reversibility requiring a perpendicular magnetic arrangement between both sensitive and hard layer, the magnetization of the latter have been hardened by pinning it with an antiferromagnetic material. The specific geometry of the design have been engineered in order to optimize the magnetic response of the soft layer via the different magnetic torques exerted on it essentially played by the dipolar fields or shape anisotropy, and the external magnetic field to detect. The smaller dimensions in width and in gap are then respectively of 2 μm and 3 μm to benefit of the full shape anisotropy formatting the magnetic response.

    The present situation was introduced of the geothermal power generation in Kyushu. In Kyushu, where there are lots of volcanos and abundant geothermal resources, the geothermal exploration has been made since long ago. Three non-utility use units at three geothermal power generation points and six commercial use units at five points are now in operation in Kyushu. The total output is approximately 210 MW, about 40% of the domestic geothermal power generation. At Otake and Hacchobaru geothermal power plants, the Kyushu Electric Power Company made the geothermal resource exploration through the installation/operation of power generation facilities. At the Otake power plant, a geothermal water type single flashing system was adopted first in the country because of its steam mixed with geothermal water. At the Hacchobaru power plant, adopted were a two-phase flow transportation system and a double flashing system in which the geothermal water separated from primary steam by separator is more reduced in pressure to take out secondary steam. Yamakawa, Ogiri and Takigami power plants are all for the joint exploration. Geothermal developers drill steam wells and generate steam, and the Kyushu Electric Power Company buys the steam and uses it for power generation. 5 figs., 1 tab.

    The Cochrane Collaboration was established in 1993, following the opening of the UK Cochrane Centre in 1992, at a time when searching for studies for inclusion in systematic reviews was not well-developed. Review authors largely conducted their own searches or depended on medical librarians, who often possessed limited awareness and experience of systematic reviews. Guidance on the conduct and reporting of searches was limited. When work began to identify reports of randomized controlled trials (RCTs) for inclusion in Cochrane Reviews in 1992, there were only approximately 20,000 reports indexed as RCTs in MEDLINE and none indexed as RCTs in Embase. No search filters had been developed with the aim of identifying all RCTs in MEDLINE or other major databases. This presented The Cochrane Collaboration with a considerable challenge in identifying relevant studies.Over time, the number of studies indexed as RCTs in the major databases has grown considerably and the Cochrane Central Register of Controlled Trials (CENTRAL) has become the best single source of published controlled trials, with approximately 700,000 records, including records identified by the Collaboration from Embase and MEDLINE. Search filters for various study types, including systematic reviews and the Cochrane Highly Sensitive Search Strategies for RCTs, have been developed. There have been considerable advances in the evidence base for methodological aspects of information retrieval. The Cochrane Handbook for Systematic Reviews of Interventions now provides detailed guidance on the conduct and reporting of searches. Initiatives across The Cochrane Collaboration to improve the quality inter alia of information retrieval include: the recently introduced Methodological Expectations for Cochrane Intervention Reviews (MECIR) programme, which stipulates 'mandatory' and 'highly desirable' standards for various aspects of review conduct and reporting including searching, the development of Standard Training

  12. The Global Network of Isotopes in Precipitation after 55 years: assessing past, present and future developments

    The Global Network of Isotopes in Precipitation (GNIP) is a global observation programme operated by the International Atomic Energy Agency (IAEA), in cooperation with the World Meteorological Organization (WMO) and more than 100 contributing institutions worldwide. GNIP has been the primary repository for baseline stable (δ18O, δ2H) and radioactive (3H) isotope data since its foundation in 1960. The impetus for GNIP was the monitoring of radioactive fallout from atmospheric thermonuclear testing and resulting tritium levels of precipitation, but tritium together with stable isotopes was recognized as a key to understanding hydrological processes. Later, new applications were developed focusing on hydrometeorology and paleoclimatic research. Increasingly, GNIP data are being used more widely in ecological and forensic investigations, e.g. for tracking of migratory animals. The GNIP database comprises more than 135,000 isotopic records (δ18O: 63,000; δ2H: 55,000; 3H: 63,000) of monthly composite precipitation samples from more than 1,000 stations worldwide. About 300 stations are currently active for stable isotopes and ca. 100 for tritium. Data for most of the active stations is available up to 2013. Several national isotopic observation networks (e.g. in Austria, Australia, China or the United States of America) exist besides GNIP, complementing precipitation isotope data at national levels. The spatially and temporally discrete nature of the GNIP dataset induces coverage gaps. Recently, highly-resolved gridded datasets were established to help overcome this deficiency through geostatistical prediction models. These 'isoscape' (isotopic landscapes) are based on combinations of multiple regression and interpolation methods, with a range of parameterization available at regional and global levels. Attempts to bridge the gap between 'one-size-fits-all' global parameterization and improved predictions at regional and local levels led to the establishment of a

  13. Three-day dendritic cells for vaccine development: Antigen uptake, processing and presentation

    2010-09-01

    Full Text Available Abstract Background Antigen-loaded dendritic cells (DC are capable of priming naïve T cells and therefore represent an attractive adjuvant for vaccine development in anti-tumor immunotherapy. Numerous protocols have been described to date using different maturation cocktails and time periods for the induction of mature DC (mDC in vitro. For clinical application, the use of mDC that can be generated in only three days saves on the costs of cytokines needed for large scale vaccine cell production and provides a method to produce cells within a standard work-week schedule in a GMP facility. Methods In this study, we addressed the properties of antigen uptake, processing and presentation by monocyte-derived DC prepared in three days (3d mDC compared with conventional DC prepared in seven days (7d mDC, which represent the most common form of DC used for vaccines to date. Results Although they showed a reduced capacity for spontaneous antigen uptake, 3d mDC displayed higher capacity for stimulation of T cells after loading with an extended synthetic peptide that requires processing for MHC binding, indicating they were more efficient at antigen processing than 7d DC. We found, however, that 3d DC were less efficient at expressing protein after introduction of in vitro transcribed (ivtRNA by electroporation, based on published procedures. This deficit was overcome by altering electroporation parameters, which led to improved protein expression and capacity for T cell stimulation using low amounts of ivtRNA. Conclusions This new procedure allows 3d mDC to replace 7d mDC for use in DC-based vaccines that utilize long peptides, proteins or ivtRNA as sources of specific antigen.

The integral tests are described which are now being implemented by the Japanese Government to check the effectiveness of the State's System, which must be maintained by the Government under the Safeguards Agreement between Japan and the IAEA under the Treaty on Non-Proliferation of Nuclear Weapons, ratified by Japan in June 1976. A joint experiment has been now implemented by the Nuclear Safety Bureau and the NMCC for knowing and improving the precision and accuracy of analytical measurements used at the bulk-facilities. JAERI, is conducting various R and D work on its own, and through cooperation with NMCC, NSB etc. The authors describe the results of non-destructive γ-spectrometry for the development of isotopic correlation techniques, as well as for the identification, and also refer briefly to measurement methods using the Fast Critical Assembly in JAERI. Measurement methods used in the Pu-fabrication facility of the PNC, and the problem of spent fuels application of safeguards for the reprocessing plant are discussed. The accounting reports coming from Japanese facilities are processed by the computer at the NMCC, and converted into (a) the State's material balance, and (b) the formats to be sent to IAEA. The authors discuss the experience of such data-processing as well as the developmental works for analysing MUF. As a part of the integral test, the experiences concerning planning and performance of inspection are discussed. The present status and future plans of the system of national analytical laboratories are described

    Different multidisciplinary therapeutic strategies and technical approaches are used today in cancer therapy. Among the techniques involving ionizing radiation, therapeutic applications of radioactive nuclides deserve a particular interest ; some clinical indications are well established, while several others are now being investigated, and some of them are promising. The efficacy of radionuclides in therapy often depends on technical factors such as specific activity, purity, chemical presentation, availability, etc. These factors are closely related, at least partly, to the production methods. This justifies the organization of the present Consultant's meeting by the IAEA. Brief information on cancer, its socio-economic aspects, and some data concerning cure rate are presented first

    2007-01-01

    Complete test of publication follows. Quality control is now an accepted activity within the overall radiation protection framework for diagnostic radiology. Indeed it is now a legal requirement within Member States specified in EC Directives that establish the basic requirements for radiation protection in medicine. This was not always the case and its historical development can be considered in three parts: 1) The development of test procedures and standardisation of practices; 2) Harmonisation of initiatives and the creation of a European dimension in such practices; 3) Its role and function in a changing and evolving technological environment - current status and future needs. The development of tests methods for diagnostic X-ray equipment was initially intimately related to the development of a scientific basis for the X-ray imaging process. Knowledge of the physical basis for image production in film-screen and fluoroscopic processes required the definition and specification and measurement of particular parameters within the image forming chain. The development of test methods and the necessary measuring equipment involved ongoing research and development by physical scientists throughout Europe and North America. However, the many different approaches employed meant that results of measurements could not always be compared. However, once acceptable test methods and equipment had been developed it was possible to standardise practices through the development of test protocols. In 1980 a foundation for collective European actions was established through the EC radiation protection research and development programme. This helped to establish a European wide forum for actions in the field of medical radiation protection including quality control. These initiatives were driven by EC Directives, which were concerned with protection of the worker, general public and patients from medical practices that utilised ionising radiation.

    Compare the cognitive and motor development in overweight/obese infants versus normal-weight peers and investigate the correlation of body weight, body length and body mass index with cognitive and motor development. We conducted a cross-sectional study with 28 overweight/obese infants and 28 normal-weight peers between 6 and 24 months of age. Both groups were evaluated with cognitive and motor scales of the Bayley-III infant development test. The t-test for independent samples was performed to compare the groups, and the Spearman correlation was used to verify the association between variables. Overweight/obese infants showed lower cognitive and motor composite scores than their normal-weight peers. A significant negative association was found of body weight and body length with cognitive development and of body mass index with motor development. This is the first study that found an effect on both cognitive and motor development in overweight/obese infants when compared with normal-weight peers between 6 and 24 months of age.

    China is a developing country rich in coal, petroleum and hydropower resources. In the past ten years, energy production in China has had a large increase, but along with the development of economy, energy demands increase even more rapidly. Many problems exist in China's energy system. Considering the large energy demand in the near future and long-term energy strategy, China has already decided to develop nuclear power gradually. The first several nuclear power stations are being and will be built in the South-east sea shore region. Two 900 MW PWRs (from France) and one 300 MW PWR (home made) are now under construction at Daya Bay (Kwangton Province) and Qin Shan (Zhejiang Province). The succeeding PWR power plants are being planned. PWR nuclear power station has been selected for the beginning of China's nuclear power plan. For large scale utilization of nuclear power in the next century, the development of advanced reactor type with good safety and economy performances and high uranium utilization rate (uranium resources in China is not rich enough) is strategically important. HTGR, due to its inherent safety characteristics, high heat efficiency, flexible fuel system and wide application fields, is a prospective advanced reactor type. Research and development on HTGR have already been included in China's national technical development program and are going on smoothly

    1984-01-01

    The feature of carbide fuel is that it has the doubling time as short as about 13 years, that is, close to one half as compared with oxide fuel. The development of the carbide fuel in the past 10 years has been started in amazement. Especially in the program of new fuel development in USA started in 1974, He and Na bond fuel attained the burnup of 16 a/o without causing the breaking of cladding tubes. In 1984, the irradiation of the assembly composed of 91 fuel pins in the FFTF is expected. On the other hand in Japan, the fuel research laboratory was constructed in 1974 in the Oarai Laboratory, Japan Atomic Energy Research Institute, to carry out the studies on carbide fuel. In the autumn of 1982, two carbide fuel pins with different chemical composition have been successfully made. Accordingly, the recent status of the development is explained. The uranium-plutonium mixed carbide fuel is suitable to liquid metal-cooled fast breeder reactors because of large heat conductivity and the high density of nuclear fission substances. The thermal and nuclear characteristics of carbide fuel, the features of the reactor core using carbide fuel, the chemical and mechanical interaction of fuel and cladding tubes, the selection of bond materials, the manufacturing techniques for the fuel, the development of the analysis code for fuel behavior, and the research and development of carbide fuel in Japan are described.

    The International Atomic Energy Agency (IAEA) is the organization within the UN family with a statutory mandate to establish standards for the protection of health and environment against ionizing radiation, and to provide for the application of those standards. As part of these functions, the IAEA periodically reviews the status and continued relevance of the standards to the needs of its Member States. Recent work on the development of standards for the radioactive discharge control includes development of practical guidance for setting discharge limits, elaboration on methodology for the radiation protection of non-human species, and preparation of guidance on environmental monitoring for radiation protection purposes. Development of these safety documents is influenced by recent international and regional tendencies, based on social initiatives, to reduce radioactive discharges substantially below levels justified by radiological criteria. The IAEA has developed preliminary guidance on practical aspects of setting discharge limits, which included a review of national regulatory experience in this regard. This review suggested that societal pressures and regulatory practicalities results in discharge controls that were likely to be more restrictive that those that would be implied by formal optimization techniques. Regulatory review of authorizations includes a number of considerations, including predicted doses to members of the critical group, but the suitability of abatement forms a greater part in the decision-making process than allowed for in previous safety guidance. The IAEA has, in recent years, established a programme of work specifically addressing the development of safety standards on assessing the impact of ionizing radiation on non-human species, in co-operation with other relevant international organizations. The main issues arising will be summarised in the paper with the main focus on an exploration of the possible form of future regulatory

  16. Present status of design, research and development of nuclear fusion reactors and problems

    International Nuclear Information System (INIS)

    1983-04-01

    Seven years have elapsed since the publication of ''Progress of nuclear fusion research and perspective toward the development of power reactors'' by the Atomic Energy Society of Japan in August, 1976. During this period, the research and development of nuclear fusion have changed from plasma physics to reactor technology, being conscious of the realization of fusion reactors. There are the R project in the Institute of Plasma Physics, Nagoya University, and the design and construction of JT-60 in Japan Atomic Energy Research Institute, to put it concretely. Now the research and development taking the economical efficiency into account are adopted. However, the type of fusion reactors is not reduced to tokamak type, accordingly the research and development to meet the diverse possibilities are forwarded. The progress of tokamak reactor research, core plasma design, nuclear design and shielding design, thermal structure design, the design of superconducting magnets, disassembling and repair, safety, economical efficiency, the conceptual design of other types than tokamak and others are reported.

    High temperature gas-cooled reactors can supply the heat of about 1000degC, and the high efficiency and the high rate of heat utilization can be attained. Also they have the features of excellent inherent safety, the easiness of operation, the high burnup of fuel and so on. The heat utilization of atomic energy in addition to electric power generation is very important in view of the protection of global environment and the diversification of energy supply. Japan Atomic Energy Research Institute has advanced the construction of the high temperature engineering test and research reactor (HTTR) of 30 MW thermal output, aiming at attaining the criticality in 1998. The progress of the development of a high temperature gas-cooled reactor is described. For 18 years, the design study of the reactor was advanced together with the research and development of the reactor physics, fuel and materials, high temperature machinery and equipment and others, and the decision of the design standard and the development of computation codes. The main specification and the construction schedule are shown. The reactor building was almost completed, and the reactor containment vessel was installed. The plan of the research and development by using the HTTR is investigated. (K.I.)

    1994-01-01

    This address by the Peruvian delegation to the Third Preparatory Committee Meeting for the International Conference on Population and Development focuses on four points in the proposed Plan of Action that might require further development. First, the link between drug trafficking and environmental degradation should be recognized. Cultivation of narcotic plants contributes to deforestation of the tropical forest and contamination of rivers, and along with terrorism has caused considerable population movement in Peru. The second point is that widespread poverty, limited investment in human capital, insufficient institutional capacity, and the external debt burden of the developing countries are clearly interrelated with sociodemographic processes and decisively affect the capacity of the nation to implement population policies and programs as a function of current and future international commitments. The third point is that, in the area of information, education, and communication, attention should be given to the entire life cycle and the entirety of themes related to population. Finally, coordinated programs between public and private institutions and nongovernmental organizations at the national level, and between the U.N. Population Fund, the Population Commission, and the Commission on Sustainable Development at the international level, should be organized to assure effective follow-up on Plan of Action proposals and agreements. Peru has participated in a wide variety of international conferences and activities related to population, and was a major participant in the subregional preparatory conference of the Andean nations.

    BATAN, started out as a governmental committee established in 1954, has a new organizational structure, based on Presidential Decree of 1998. BATAN has developed its researches in almost practically all-nuclear fields. The situation in Indonesia has been much influenced by the economic crisis, which still being faced by Indonesia. BATAN's strategic planning is described in four areas, those are: 1. Basic human needs, 2. Energy, natural resources and environment, 3. Industry, 4. Socio-cultural and institution. Priority has been given to fulfill, as well as to promote agriculture, health and the industry related to people's welfare, which may develop and improve the immediate needs of the people. In the meantime, we have made considerable investments in manpower development in anticipation of the introduction of nuclear power. BATAN, as of September 1999, has 3889 employees, 26 % of them have bachelor degree, 6 % hold master degrees, and only 2% hold doctoral degree, a total of 34 % employees with university education. Others 11 % have either non-vocational or vocational education beyond High School. The rest of 55 % have high school education or lower, they are administrative clerks (25 %) or technicians (30 %). In the human resources development, BATAN's Education and Training Center, in collaboration with some universities and other national/international institutions, is managing education and training programs for employees. To date, there are 43 BATAN employees studying in various universities in Japan, while another 42 employees are studying in six different countries. Research and Development that have more direct impact to the community will become a priority in the coming years. Without undermining the importance of basic research in advanced fields, we will expect to have more research on application to optimize utilization of research reactors and related facilities for the benefit of both the energy and non-energy sectors.

    The European Event on Technology (EET), is a major meeting on technologies, their evolution and their industrial and social implications. In less than a decade, sustainable development has become both an economic and a political priority. It was urgent and legitimate that those who are the mainsprings should take hold of the subject and give it technological content, estimate its costs and define clear timetables. The debates consist of: plenary sessions on environmental, social and economic stakes of sustainable development and the challenges for, and commitment of engineers, managers and politicians with respect to these goals; and workshops, which provide an overview on recently acquired or upcoming technologies developed by sector. These proceedings present several technologies of interest for the energy and environment sectors: Energy efficiency of buildings: towards energy autonomy; superconductors enable in new millennium for electric power industry; advanced gas micro-turbine-driven generator technology; environmental and technical challenges of an offshore wind farm; future nuclear energy system; transports and propulsion systems: modelling combustion in engines: progress and prospects for reducing emissions; on-board computers: reduction in consumption and emissions of engine-transmission units for vehicles; polymer-lithium batteries: perspectives for zero-emission traction; hybrid vehicles and energy/environmental optimization: paths and opportunities; fuel cells and zero-emission: perspectives and developments; urban goods transport: towards a drop in congestion and nuisance; new hybrid propulsion for buses: energy/environmental optimization; Tram-train: city-suburbs concept without transshipment; safety: computerization in controlling nuclear power plant processes (EPR architecture); refractory materials: a key factor for the increase in aero-turbo-engines output; the contribution of waste processing to the production of greenhouse gases; waste as a

    Full Text Available Lymphogranuloma venereum (LGV is a sexually transmitted infectious disease caused by serovars L1, L2 and L3 of Chlamydia trachomatis. The initial presentation is usually a painless ulcerated papule on the genitalia or distal proctitis. The progression of the infection can lead to major complications: rectal strictures, intestinal obstruction or perforation. We present five cases of LGV proctitis as the initial presentation of the disease. All patients were male, mean age 44.6 years, with positive serology to human immunodeficiency virus (HIV and promiscuous men who have sex with men (MSM. The initial diagnosis was made by rectosigmoidoscopy indicated for pain and anal discharge. All cases were confirmed by polymerase chain reaction technique in rectal tissue. Endoscopic images obtained showed a great variety of rectal lesions, from mild erythema of the mucosa and ulcers to deep ulcers with elevated borders and purulent exudate. All cases were resolved after treatment with doxycycline for 3 weeks. It emphasizes the importance of suspecting this re-emerging disease in patients with risk factors (HIV and MSM, with the aim of early treatment and to avoid major complications.

    Handa, Muneo; Suzuki, Yasufumi.

    One Oarai characteristic of a carbide fuel is that its doubling time is about 13 years which is only about half as long as that of an oxide fuel. The development of carbide fuels in the past ten years has been truly remarkable. Especially, through the new fuel development program initiated in 1974 in the United States, success has been achieved with respect to He- and Na-bond fuels in obtaining a 16 a/o burning rate without damage to cladding tubes. In 1984 at FFTF, a radiation of a fuel assembly consisting 91 fuel pins is contemplated. On the other hand, in Japan, in 1974, a Fuel Research Wing specializing in the study of carbide fuels was constructed in the Oarai Laboratory of the Atomic Energy Research Institute and in the fall of 1982, was successful in fabricating two carbide fuel pins having different chemical compositions

  11. Present capabilities and new developments in antenna modeling with the numerical electromagnetics code NEC

    Burke, G.J.

    1988-04-08

    Computer modeling of antennas, since its start in the late 1960's, has become a powerful and widely used tool for antenna design. Computer codes have been developed based on the Method-of-Moments, Geometrical Theory of Diffraction, or integration of Maxwell's equations. Of such tools, the Numerical Electromagnetics Code-Method of Moments (NEC) has become one of the most widely used codes for modeling resonant sized antennas. There are several reasons for this including the systematic updating and extension of its capabilities, extensive user-oriented documentation and accessibility of its developers for user assistance. The result is that there are estimated to be several hundred users of various versions of NEC world wide. 23 refs., 10 figs.

  12. Theory of defects in Si and Ge: Past, present and recent developments

    International Nuclear Information System (INIS)

    Estreicher, S.K.; Backlund, D.; Gibbons, T.M.

    2010-01-01

    Over the past few decades, considerable progress has been achieved in the theoretical predictions of a wide range of properties of defects in semiconductors. In addition to structures, energetics, spin and charge densities, theory now routinely predicts accurate vibrational properties of defects, and thus connects to the optical characterization of light impurities. However, the positions of gap levels have yet to be predicted with systemically reliable accuracy. Today, supercells much larger than in the past are being used to describe defect centers from first principles. Systems large enough to study the dynamics of extended defects can be handled near the first-principles level. This paper contains a brief review of the key developments that have rendered theory quantitatively useful to experimentalists and an overview of the current 'state-of-the-art' and ongoing developments. Some of the remaining challenges are discussed, with examples in Si and Ge.

  13. Perspective on present and future alloy development efforts on austenitic stainless steels for fusion application

    International Nuclear Information System (INIS)

    Maziasz, P.J.

    1984-01-01

    The purpose of this paper is to address important questions concerning how to effect further alloy development of austenitic stainless steels for resistance, and to what extent the behavior of other properties under irradiation, such as strength/embrittlement, fatigue/irradiation creep, corrosion (under irradiation), and radiation-induced activation must be influenced. To summarize current understanding, helium has been found to have major effects on swelling and embrittlement, but several metallurgical avenues are available for significant improvement relative to type 316 stainless steel. Studies on fatigue and irradiation creep, particularly including helium effects, are preliminary but have yet to reveal engineering problems requiring additional alloy development remedies. The effects of irradiation on corrosion behavior are unknown, but higher alloy nickel contents make thermal corrosion in lithium worse. 67 refs

    2017-08-01

    Full Text Available The rapid spread of antibiotic-resistant bacterial strains necessitates the development of new antibacterial agents and a review of the guidelines for etiological treatment of bacterial infections, including pneumonia. Currently, new antibacterial agents are being developed that disrupt the biosynthesis of peptidoglycan, teichoic and lipoteichoic acids, and also block the attachment of virulent factors to the bacterial wall. New molecules of old classes of antibiotics and representatives of new classes of antibiotics with their targets (lipid II and III, teichoic and lipoteichoic acids, alanine racemase, and sortase A will become practical tools in clinical practice in the very near future. The goals and mechanisms of action of new antibacterial compounds predetermine their clinical prospects in future strategies for the treatment of infectious bacterial diseases.

  17. Present status of research and development of nuclear steelmaking in Japan

    International Nuclear Information System (INIS)

    Shimokawa, Keiji

    1979-01-01

    The Japanese steel industry consumes about 18% of total energy consumption in Japan, and 56 million tons of coking coal were imported in 1977 at the cost of approximately $3.3 billion. Securing of required quantity of coking coal, price negotiation, the transport and storage of coal, and environmental pollution are the problems concerning the steel industry. In order to solve these problems, the introduction of atomic energy to steel-making is considered. The use of high temperature gas-cooled reactors is capable of supplying large quantities of heat and electric power which are required for steel-making. The Committee on Utilization of Nuclear Energy, the Iron and Steel Institute of Japan, was established in 1968, and the research and development of nuclear steel-making were started as a national project in 1973. The outline of nuclear steel-making system is explained. The Japan Atomic Energy Research Institute is promoting the research and development on a multi-purpose HTGR with 1000 deg C outlet helium temperature. The research and development in progress now are as follows: high temperature heat exchangers, heat resistant superalloys, high temperature heat insulating materials, reducing gas-producing unit, reduced iron-producing system, and the total system for nuclear steel-making.

    2008-03-01

    The current national project on coated conductors using Y-system superconductors has been carried out over the project period (FY2003-FY2007). In this paper, the current status and the future prospect of this project are reviewed. The high performance tape development group, consisting of Fujikura and SRL-NCCC, has worked on the tape by PLD-REBCO superconducting layers on PLD-CeO2/IBAD-GZO buffered substrates. A high product of Ic and L, higher than 112 166 A m, was achieved in a 368 m-304.8 A GdBCO tape whose Ic value is mostly above 350 A/cm in width. The performance under magnetic field was also improved up to 42 A at 3 T in a GdBCO short film with doping of ZrO2. 61 m long GdBCO tape with ZrO2 doping showed a high Ic value of 220 A at self field and 30 A at 3 T. On the other hand, another group focusing on low production cost has worked on TFA-MOD and MOCVD processes. The extremely high Ic value of 735 A/cm-w was obtained in TFA-MOD films on PLD-CeO2/IBAD-GZO/Hastelloy substrate due to the effect of Ba-poor nominal composition. In efforts towards long tape production by the SWCC group, a 200 m long tape with a high Ic value of 200 A/cm-w was obtained using a batch-type furnace. The Ic × L value of this tape was 40 000 A m, which is the highest value in the world obtained by the TFA-MOD process. Based on the above achievements in coated conductor process development, two new additional goals were set in the project. One is the development of extremely low cost tape and the other is the development of the basic technologies for making electric power devices of cables, transformers, motors, current-limiters and cryocoolers. Some of the new investigations have already revealed marvellous results, such as a 15 kW motor, low AC loss coils, low AC loss cables, etc.

A high product of I c and L, higher than 112 166 A m, was achieved in a 368 m-304.8 A GdBCO tape whose I c value is mostly above 350 A/cm in width. The performance under magnetic field was also improved up to 42 A at 3 T in a GdBCO short film with doping of ZrO 2 . 61 m long GdBCO tape with ZrO 2 doping showed a high I c value of 220 A at self field and 30 A at 3 T. On the other hand, another group focusing on low production cost has worked on TFA-MOD and MOCVD processes. The extremely high I c value of 735 A/cm-w was obtained in TFA-MOD films on PLD-CeO 2 /IBAD-GZO/Hastelloy substrate due to the effect of Ba-poor nominal composition. In efforts towards long tape production by the SWCC group, a 200 m long tape with a high I c value of 200 A/cm-w was obtained using a batch-type furnace. The I c x L value of this tape was 40 000 A m, which is the highest value in the world obtained by the TFA-MOD process. Based on the above achievements in coated conductor process development, two new additional goals were set in the project. One is the development of extremely low cost tape and the other is the development of the basic technologies for making electric power devices of cables, transformers, motors, current-limiters and cryocoolers. Some of the new investigations have already revealed marvellous results, such as a 15 kW motor, low AC loss coils, low AC loss cables, etc

The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

    This year is the 10th year in the ''Second stage nuclear fusion research and development project'', and the main plan to construct a critical plasma testing apparatus, JT-60, is about to be completed. The test of the power source and control system, and the assembling of the main body were finished, and the final general test is about to be started. In foreign countries, already experiment was begun with the TFTR and the JET, and the formation of the plasma at 20 million deg with the containment time of about 0.3 sec was accomplished. The results of heating experiment by incorporating heating devices are anxiously waited for. As the next generation projects, the conceptual design of the burning core experiment aiming at the attainment of self ignition condition was started in USA, and the next European torus is to be developed in EC before reaching the prototype DEMO. In Japan, it is intended to advanced to the attainment of self ignition condition and an experimental reactor for verifying nuclear fusion technology. In USSR, the construction of a superconducting tokamak T-15 is likely to be completed in 1986. The international cooperation is expected because of the financial condition of respective countries.

    A system dedicated to the optical transmittance characterization of Fresnel lenses has been developed at NREL, in collaboration with the UPM. The system quantifies the optical efficiency of the lens by generating a performance map. The shape of the focused spot may also be analyzed to understand change in the lens performance. The primary instrument components (lasers and CCD detector) have been characterized to confirm their capability for performing optical transmittance measurements. Measurements performed on SoG and PMMA lenses subject to a variety of indoor conditions (e.g., UV and damp heat) identified differences in the optical efficiency of the evaluated lenses, demonstrating the ability of the Scanning Lens Instrument (SLI) to distinguish between the aged lenses.

    X-ray beam micro-analysis has advanced rapidly in these years in conjunction with the development of powerful X-ray sources. Among a variety of methods being attempted, the method using a collimated narrow beam has been important because of high brightness, and of usability in both regions of soft and hard X-rays. In the soft X-ray region, the focused beam is formed by a fresnel zone plate or a Schwaltzschild mirror assembly, and can be used for scanning transmission microscope or scanning photoelectron microscope. In the hard X-ray region, the beam is formed by grazing incidence mirrors, and can be used for X-ray fluorescence micro-analysis for obtaining elemental mapping. In this report, the recent progress on the soft X-ray scanning microscopy and the X-ray microprobe has been surveyed, together with the improvement on the related optical elements. (author) 84 refs

    The aim of this paper is to report the development, construction, and psychometric properties of the new instrument Sense of Security in Care - Patients' Evaluation (SEC-P) in palliative home care. The preliminary instrument was based on a review of the literature and an analysis of qualitative interviews with patients about their sense of security. To test the instrument, 161 patients (58% women) in palliative home care were recruited and participated in a structured interview based on a comprehensive questionnaire (response rate 73%). We used principal component analysis to identify subscales and tested the construction in correlation with other scales and questions representing concepts that we expected to be related to sense of security in care. The principal component analysis resulted in three subscales: Care Interaction, Identity, and Mastery, built on a total of 15 items. The component solution had an explained variance of 55%. Internal consistency of the subscales ranged from 0.84 to 0.69. Inter-scale correlations varied between 0.40 and 0.59. The scales were associated to varying degrees with the quality of the care process, perceived health, quality of life, stress, and general sense of security. The developed SEC-P provides a three-component assessment of palliative home care settings using valid and reliable scales. The scales were associated with other concepts in ways that were expected. The SEC-P is a manageable means of assessment that can be used to improve quality of care and in research focusing on patients' sense of security in care. Copyright © 2014 John Wiley & Sons, Ltd.

    It is well known in the fusion engineering community that the plasma confinement performance in magnetic fusion devices is strongly affected by edge-plasma interactions with surface components. These plasma-material interactions (PMI) include fuel particle recycling and impurity generation both during normal and off-normal operation. To understand and then to control PMI effects, considerable effort has been made, particularly over the last decade in US, supported by Department of Energy, Division of Development and Technology. Also, because plasma-facing components are generally expected to receive significant amount of heat due to plasma bombardment and run-away electrons, materials must tolerate high-heat fluxes (HHF). The HHF-component research has been conducted in parallel with PMI research. One strong motivation for these research activities is that DT-burning experiments are currently planned in the Tokamak Test Fusion Reactor (TFTR) in early 1990s. Several different but mutually complementary approaches have been taken in the PMI+HHF research. The first approach is to conduct PMI experiments using toroidal fusion devices such as TFTR. The second one is to simulate elemental processes involved in PMI using ion beams and electron beams, etc. The last one but not least is to use non-tokamak plasma facilities. Along with these laboratory activities, new materials have been developed and evaluated from the PMI+HHF point of view. In this paper, several major PMI+HHF research facilities in US and their activities are briefly reviewed. 21 refs., 10 figs., 2 tabs

    In this research project the development of the wood products industry and its operating environment in Finland was studied using statistical data mainly from years 1995 - 2003. In this context, the wood products industry includes the sawmilling industry, the plywood and other wood panel industry, prefabricated wooden housing and the building joinery industry, wood packing manufacture and the manufacture of other wooden products. The development of the wood products industry and its operating environment has been estimated by combining statistical data about the business economy, production economy and the national economy from the Central Statistical Office of Finland together with data from the Finnish Forest Research Institute. Based on statistical data, the wood product markets, profitability and cost structure of branches, input market, use of labour force and investments have been studied. The economic importance of the wood products industry has been estimated at a national and a local level. Challenges facing wood products industry branches have been analysed using example calculations based on input-output theory. In the evaluation method, the business environment of the wood products industry branches and related branches, have been described with a use table at basic prices commonly using in the national economy. This method has enabled the direct and indirect effects of simultaneous quantity and price changes occurring in the wood product markets and markets related to the wood product industry, to be analysed. In the example calculations, variation of sawn timber production and log import, as well as the increments of sawn timber upgrading, wood product usage in building, wood panel production and purchase energy price, were reviewed

    Butterfly is an important bio-indicator for biodiversity monitoring and ecological environment assessment. In Europe, the species composition, population dynamics, and distribution pattern of butterfly have been monitored for decades, and many long-term monitoring schemes with international effects have been implemented. These schemes are aimed to assess the regional and national variation trends of butterfly species abundance, and to analyze the relationships of this species abundance with habitat, climate change, and other environmental factors, providing basic data for researching, protecting, and utilizing butterfly resources and predicting environmental changes, and playing important roles in the division of butterfly' s threatened level, the formulation of related protection measures, and the protection and management of ecological environment. This paper reviewed the history and present status of butterfly monitoring in Europe, with the focus on the well-known long-term monitoring programs, e. g. , the UK Butterfly Monitoring Scheme and the Germany and European Union Butterfly Monitoring Scheme. Some specific proposals for conducting butterflies monitoring in China were suggested.

    1985-03-01

    In 1982, the three Committees (FAO, IAEA, WHO) in charge of examining the documentation relating to applications for authorization reacted favourably to the summary report on the toxicology of irradiated foodstuffs submitted by the CEA. New applications need no longer contain a new toxicological study if the dose is lower than 10 kGy. This liberalization of procedure has encouraged industrialists to prepare application documentations. Technically convincing but economically disappointing experiments have shown that the two existing radiation sterilization facilities are unsuitable for harvested agricultural products. It is therefore advisable to set up units which could meet the requirements of the food industry. In the Marseille region it is planned to build a multipurpose commercial facility and a development facility by 1986. Moreover, a firm in Western France is reported soon to be acquiring an electron accelerator for the radicidation of mechanically pointed and frozen poultry. Concurrently with these activities a large information campaign has been undertaken. However, it is too early to offer to the public products for large-scale human consumption which have been treated with ionizing radiation [fr

    If one wants to know whether something is good or bad for people, in the long run, there is only one way to be sure. This is to follow up those who have tried it, and those who have not, to see what has happened to them. For people exposed to agents suspected of causing cancer, the follow-up period may be a number of decades, and this often creates difficulities in carrying out appropriate studies using conventional methods. Today, however, computer techniques make it possible to search rapidly for the death records and cancer records pertaining to very large study populations that are believed to be Σat riskΣ because of exposures to suspected carcinogens, received for example in the workplace or as a result of medical diagnostic and treatment procedures. All that is required is adequate personal identifying information, in conjunction with the exposure data. Without this, however, the risks may never be detected, and quantified, unless they are very large, and protective measures may never be instituted. The development, in Canada, of the computuer procedures and record files for such work, will be reviewed. Future trends in these matters should result in earlier detection of even small risks from carcinogens in the workplace and elsewhere. Large-scale cancer epidemioloy is already technically feasible and, wherever the public and those at risk want it, it can be carried out under conditions which carefuuly guard the privacy of the individual.

    2017-03-01

    Scanning confocal microscopy is a standard choice for many fluorescence imaging applications in basic biomedical research. It is able to produce optically sectioned images and provide acquisition versatility to address many samples and application demands. However, scanning a focused point across the specimen limits the speed of image acquisition. As a result, scanning confocal microscope only works well with stationary samples. Researchers have performed parallel confocal scanning using digital-micromirror-device (DMD), which was used to project a scanning multi-point pattern across the sample. The DMD based parallel confocal systems increase the imaging speed while maintaining the optical sectioning ability. In this paper, we report the development of an add-on kit for high-speed and low-cost confocal microscopy. By adapting this add-on kit to an existing regular microscope, one can convert it into a confocal microscope without significant hardware modifications. Compared with current DMD-based implementations, the reported approach is able to recover multiple layers along the z axis simultaneously. It may find applications in wafer inspection and 3D metrology of semiconductor circuit. The dissemination of the proposed add-on kit under $1000 budget could also lead to new types of experimental designs for biological research labs, e.g., cytology analysis in cell culture experiments, genetic studies on multicellular organisms, pharmaceutical drug profiling, RNA interference studies, investigation of microbial communities in environmental systems, and etc.

    Controlled thermonuclear ignition and subsequent burn will be demonstrated in a couple of years on the central ignition scheme. Fast ignition has the high potential to ignite a fuel using only about one tenth of laser energy necessary to the central ignition. This compactness may largely accelerate inertial fusion energy development. One of the most advanced fast ignition programs is the Fast Ignition Realization Experiment (FIREX). The goal of its first phase is to demonstrate ignition temperature of 5 keV, followed by the second phase to demonstrate ignition-and-burn. The second series experiment of FIREX-I from late 2010 to early 2011 has demonstrated a high (≈20%) coupling efficiency from laser to thermal energy of the compressed core, suggesting that one can achieve the ignition temperature at the laser energy below 10 kJ. Given the demonstrations of the ignition temperature at FIREX-I and the ignition-and-burn at the National Ignition Facility, the inertial fusion research would then shift from the plasma physics era to power generation era.

    Yukawa, S.; Merkle, J.G.

    1984-01-01

    Since the early 1970's, the Sections of the ASME Boiler and Pressure Vessel Code concerned with nuclear power plant components have included fracture mechanics procedures to analyze the effects of postulated or detected flaws. These procedures are contained in Appendix G of Section III and in Appendix A of Section XI of the Code. Specifically, Appendix G procedures are concerned with designing for protection against nonductile failures while Appendix A procedures are for evaluating the disposition of flaws detected during in-service inspection. An important element of the procedures is the inclusion of recommended material fracture toughness values. This paper describes the origin and development of these recommended fracture toughness values. Since these values appear in the Code in a graphical format, the values are often referred to as reference toughness curves. In the context of Code terminology, reference toughness means the allowable values of fracture toughness for the materials of concern that can be used in conjunction with the analytical procedures of Appendices G and A. The paper discusses the basis and rationale underlying the original formulation of these reference toughness curves and the modifications incorporated into them in the course of their adoption into the Code

    The United States (US) Vision for Space Exploration, announced in January 2004, outlines the National Aeronautics and Space Administration's (NASA) strategic goals and objectives, including retiring the Space Shuttle and replacing it with new space transportation systems for missions to the Moon, Mars, and beyond. The Crew Exploration Vehicle (CEV) that the new human-rated Crew Launch Vehicle (CLV) lofts into space early next decade will initially ferry astronauts to the International Space Station (ISS) Toward the end of the next decade, a heavy-lift Cargo Launch Vehicle (CaLV) will deliver the Earth Departure Stage (EDS) carrying the Lunar Surface Access Module (LSAM) to low-Earth orbit (LEO), where it will rendezvous with the CEV launched on the CLV and return astronauts to the Moon for the first time in over 30 years. This paper outlines how NASA is building these new space transportation systems on a foundation of legacy technical and management knowledge, using extensive experience gained from past and ongoing launch vehicle programs to maximize its design and development approach, with the objective of reducing total life cycle costs through operational efficiencies such as hardware commonality. For example, the CLV in-line configuration is composed of a 5-segment Reusable Solid Rocket Booster (RSRB), which is an upgrade of the current Space Shuttle 4- segment RSRB, and a new upper stage powered by the liquid oxygen/liquid hydrogen (LOX/LH2) J-2X engine, which is an evolution of the J-2 engine that powered the Apollo Program s Saturn V second and third stages in the 1960s and 1970s. The CaLV configuration consists of a propulsion system composed of two 5-segment RSRBs and a 33- foot core stage that will provide the LOX/LED needed for five commercially available RS-68 main engines. The J-2X also will power the EDS. The Exploration Launch Projects, managed by the Exploration Launch Office located at NASA's Marshall Space Flight Center, is leading the design

    A radioimmunological method of PGE and PGFα determination has been developed to evaluate their elimination in the urine, one of the best representations of their renal synthesis. The urine is collected for 24 hours at 4 0 C then frozen to -20 0 C until the moment of analysis, which includes a preliminary extraction and chromatographic separation stage. The overall extraction and chromatographic yields are: - 78.7%+-74 (SD) for PGE (n=394) -89%+-4.1 (SD) for PGFα (n=119). The antigen-antibody reaction takes place in PBS-G pH 7.4 buffer under a final volume of 300 μl; incubation proceeds at 4 0 C for 24 hours in the presence of 4.8 pg tritiated PGE 2 or 5.4 pg tritiated PGF 2 α. Immune serum are obtained by immunisation of rabbits with a PG-bovine serumalbumin combination coupled by a carbodiimide. Those used here have an affinity constant and a sensitivity equal respectively to: - 3,7 10 10 l.mole -1 and 1,1 pg for the anti PGE immune serum adopted, - 3,1 10 10 l.mole -1 and 0,9 pg for the anti PGFα immune serum adopted. In view of non-specific interferences due to the organic solvents required for extraction and chromatography the overall sensitivity of the system should be taken as: - 2.2 pg for PGE, - 1.8 pg for PGFα. The intra and intertest reproducibilities are respectively: - 5.6% and 7.8% for PGE, 2.7% and 8.6% for PGFα [fr

    Despite increasing burden of stroke in Africa, prospective descriptive data are rare. Our objective was to describe, in The Gambia, the clinical outcome of stroke patients admitted to the Royal Victoria Teaching Hospital in the capital Banjul, to assess mortality and morbidity, and propose preventive and therapeutic measures. Prospective data were collected on consecutive patients older than 15 years old admitted between February 2000 and February 2001 with the diagnosis of nonsubarachnoid stroke. Risk factors, clinical characteristics, and social consequences were assessed using a modified National Institutes of Health Stroke Scale (mNIHSS), the Barthel Activity in Daily Living scale, the Siriraj score for subtypes, and the Bamford criteria for location/extension. Patients were followed-up at home up to 1 year after discharge. Ninety-one percent (148/162) of eligible patients were enrolled and followed-up. Hypertension and smoking were the most prevalent risk factors. Severity was high at admission, especially in women, and was strongly correlated to the outcome. mNIHSS and consciousness level on admission were strong predictors of the mortality risk. Swallowing difficulties at admission, fever, lung infection, and no aspirin treatment were, independently, risk factors for a lethal outcome susceptible to being addressed by treatment. Mortality was 41% in-hospital and 62% after 1 year. In survivors, autonomy levels improved over time. Drug compliance was poor. At home, family members provided care. Long-term socioeconomic and cultural activities were affected in most patients. Case-fatality was high compared with Western cohorts. Preventive measures can be developed. Rational treatment, in the absence of head imaging for initial assessment, requires adapted protocols. Providers should be trained, both at hospital and community levels.

    Our objective is to present a simple method for converting movie clips to animated GIFs (graphics interchange format) using Photoshop. Although animated GIF is a more reliable format than movie clips (e.g., AVI and QuickTime) for presenting dynamic data sets in PowerPoint presentations, this output format is not available on most radiology workstations. Therefore, many academic radiologists still experience the problem of incompatible codecs and missing file links when trying to show movie clips in their PowerPoint presentations. One way to resolve this issue is to convert the movie clips to animated GIFs. In this article, we provide a simple method for this conversion using Photoshop--a common software application used by radiologists.

    2016-08-01

    Sex development depends on the synchronous interaction of complicated genetic and hormonal events. Sex differentiation begins with sex determination, which is the assignment of the embryonic bipotential gonads as either testes or ovaries on the basis of transcriptional regulation. Hormonal regulation then directs the development of the male or female phenotype. Disruptions of this intricate cascade of events result in disorders of sexual development. A 16-year-old female adolescent presented with primary amenorrhea. Evaluation revealed female external genitalia, XY karyotype, absent gonadal tissue, and rudimentary Müllerian structures. On the basis of her constellation of findings, the most logical diagnosis was the rare embryonic testicular regression syndrome. A careful understanding of embryonic sexual development is critical to the evaluation of patients with disorders of sexual development.

    Adam M Ali

    2014-01-01

    Full Text Available Background: The literature on paediatric osteomyelitis in the developing world is scarce, and there have been calls for further characterisation of its epidemiology and the identification of factors that limit effective management in order to guide local service delivery. Our centre is a hospital serving a population of 11 million people in Tanzania. Materials and Methods: We identified patients 3 months. Twelve out of 13 with a time from symptom onset to presentation of <2 months did not develop recurrence. Conclusions: This is, to the best of our knowledge, the second largest study of paediatric osteomyelitis in the developing world. Major challenges facing this centre include a lack of availability of bacterial cultures and failure to attend follow-up. Delayed presentation of osteomyelitis to our centre is associated with recurrence of infection.

    This article presents a survey that has been led to study the acceptability of wind turbines by local populations. 11 families living in the neighbourhood of the Salleles wind farm (near Carcassonne, France) have been interviewed. A few recommendations can be drawn from this survey. It is necessary to organize information campaigns in order to make people consider wind farms as elements of the local economy. As for site choice any already visually polluted area should be barred, for wind turbines might be seen more as a supplementary negative element than as a positive element aimed at counterbalancing a dissatisfying situation.

    The gas turbine is the most widely used prime mover all over the world for either power generation or mechanical drive applications. The above fact is due to the recent great improvements that have been done especially in terms of efficiency, availability and reliability. The future for gas turbine technological development looks very promising. In fact, although tremendous growth has already taken place, there is still the potential for dramatic improvements in performance. Compared with the competitive prime movers (conventional steam power plants and reciprocating piston engines) the gas turbine technology is younger and still following a strong growth curve. The coming decades will witness the continued increasing in turbine inlet temperature, the development of new materials and refrigeration systems and the commercialization of inter cooled system and steam cooled turbines. With the very soon introduction of the {sup G }and {sup H }technology, expected single and combined cycle efficiencies for heavy duty machines are respectively 40% and 60%, while maintaining single digit levels in pollutant emissions. In this report are given wide information on gas turbine present technology (Thermodynamics, features, design, performances, emission control, applications) and are discussed the main lines for the future developments. Finally are presented the research and technological development activities on gas turbine of Italian National Agency for new Technology Energy and the Environment Energy Department.

  2. Enhanced Cognitive Walkthrough: Development of the Cognitive Walkthrough Method to Better Predict, Identify, and Present Usability Problems

    Directory of Open Access Journals (Sweden)

    Lars-Ola Bligård

    2013-01-01

    Full Text Available To avoid use errors when handling medical equipment, it is important to develop products with a high degree of usability. This can be achieved by performing usability evaluations in the product development process to detect and mitigate potential usability problems. A commonly used method is cognitive walkthrough (CW, but this method shows three weaknesses: poor high-level perspective, insufficient categorisation of detected usability problems, and difficulties in overviewing the analytical results. This paper presents a further development of CW with the aim of overcoming its weaknesses. The new method is called enhanced cognitive walkthrough (ECW. ECW is a proactive analytical method for analysis of potential usability problems. The ECW method has been employed to evaluate user interface designs of medical equipment such as home-care ventilators, infusion pumps, dialysis machines, and insulin pumps. The method has proved capable of identifying several potential use problems in designs.

  3. The Expected Net Present Value of Developing Weight Management Drugs in the Context of Drug Safety Litigation.

    Chawla, Anita; Carls, Ginger; Deng, Edmund; Tuttle, Edward

    2015-07-01

    Following withdrawals, failures, and significant litigation settlements, drug product launches in the anti-obesity category slowed despite a large and growing unmet need. Litigation concerns, a more risk-averse regulatory policy, and the difficulty of developing a product with a compelling risk-benefit profile in this category may have limited innovators' expected return on investment and restricted investment in this therapeutic area. The objective of the study was to estimate perceived manufacturer risk associated with product safety litigation and increased development costs vs. revenue expectations on anticipated return on investment and to determine which scenarios might change a manufacturer's investment decision. Expected net present value of a weight-management drug entering pre-clinical trials was calculated for a range of scenarios representing evolving expectations of development costs, revenue, and litigation risk over the past 25 years. These three factors were based on published estimates, historical data, and analogs from other therapeutic areas. The main driver in expected net present value calculations is expected revenue, particularly if one assumes that litigation risk and demand are positively correlated. Changes in development costs associated with increased regulatory concern with potential safety issues for the past 25 years likely did not impact investment decisions. Regulatory policy and litigation risk both played a role in anti-obesity drug development; however, product revenue-reflecting efficacy at acceptable levels of safety-was by far the most important factor. To date, relatively modest sales associated with recent product introductions suggest that developing a product that is sufficiently efficacious with an acceptable level of safety continues to be the primary challenge in this market.

  4. A Systematic Review of Barriers to Breast Cancer Care in Developing Countries Resulting in Delayed Patient Presentation

    Directory of Open Access Journals (Sweden)

    Ketan Sharma

    2012-01-01

    Full Text Available Background. Within the developing world, many personal, sociocultural, and economic factors cause delayed patient presentation, a prolonged interval from initial symptom discovery to provider presentation. Understanding these barriers to care is crucial to optimizing interventions that pre-empt patient delay. Methods. A systematic review was conducted querying: PubMed, Embase, Web of Science, CINAHL, Cochrane Library, J East, CAB, African Index Medicus, and LiLACS. Of 763 unique abstracts, 122 were extracted for full review and 13 included in final analysis. Results. Studies posed variable risks of bias and produced mixed results. There is strong evidence that lower education level and lesser income status contribute to patient delay. There is weaker and, sometimes, contradictory evidence that other factors may also contribute. Discussion. Poverty emerges as the underlying common denominator preventing earlier presentation in these settings. The evidence for sociocultural variables is less strong, but may reflect current paucity of high-quality research. Conflicting results may be due to heterogeneity of the developing world itself. Conclusion. Future research is required that includes patients with and without delay, utilizes a validated questionnaire, and controls for potential confounders. Current evidence suggests that interventions should primarily increase proximal and affordable healthcare access and secondarily enhance breast cancer awareness, to productively reduce patient delay.

    Full text: Data logging with prompt graphical presentation software accommodating gamma radiation signals from 12 scintillation detectors through standard RS-232 interface has been developed. Laboratory testing by detection of injected-mixed radioactive tracer in a fluid flowing inside a pipe was conducted. The radioactive mixed fluid passed through the detectors located at several points along the pipe and the generated signals correspond to the mass flow inside the pipe were recorded. Up to 10,000 data points of fast (20 millisecond) dwell time could be accumulated. Graphical presentation allowed fast interpretation while the output data were suitable for more accurate evaluation with standard software e.g. Residence Time Distribution (RTD), Computed Tomography Visualization. Further utilization in the industry, in conjunction with radiotracer techniques, for troubleshooting and process optimization will be further carried out

    Regarding to PSA CIGB- IAEA project the center will be generating a panel of monoclonal antibodies against prostatic specific antigen (PSA) free and complexed to α1 antichymotrysin, and tissue polypeptide specific (TPS) antigen as potentially useful markers for the diagnosis of prostate and breast cancer using IRMA or RIA. The panel of monoclonal antibodies would be distributed in Cuba and another countries for the development of diagnostic Kits. The detailed objectives of the contract are: 1. To obtain a panel of monoclonal antibodies against prostatic specific antigen (PSA) complexed antichymotrysin. 2. To obtain a panel of monoclonal antibodies against free PSA. 3. To study the potential use for detect free or complexed PSA in the serum of patients with benign prostatic hypertrophy or prostatic neoplasia. 4. To obtain a panel of monoclonal antibodies against TPS. 5. To develop and validate IRMA or RIA assays using the panel of monoclonal antibodies. The objectives are designed according to the present knowledge on the field of monoclonal antibodies and diagnostic kits. Basic techniques for developing monoclonal antibodies (Mabs) have been used in our division for more than 10 years. The possibility to acquire commercial PSA antigen could reduced the overall time to obtain the Mabs, according with our experience. All these aspects support the idea that the proposing Cuban institutes are able to develop this research project and that its benefits will be applicable in the country and in the region

  10. Report to the Congress: liquid metal fast breeder reactor program--past, present, and future, Energy Research and Development Administration

    International Nuclear Information System (INIS)

    1975-01-01

    The past, present, and future of the liquid metal fast breeder reactor (LMFBR) program, the Nation's highest priority energy program, are studied. ERDA anticipates that the operation of the first large commercial breeder will start in 1987, and that 186 commercial-size breeders will be in operation by the year 2000. The breeder program is made up of six major areas, each dealing with an important element of technology: reactor physics; fuels and materials; fuel recycle; safety; component development; plant experience; and facilities used in the LMFBR program. ERDA is implementing a new system for administering, managing, and controlling the breeder program that will provide increased program visibility and control. Federal funding for breeder development was $168 million in FY 1971, accounting for 40% of the total Federal R and D energy budget; in FY 1976 Federal funding for this program will be $474 million, only 26% of total Federal funding for energy research. Besides Federal funds, over half a billion dollars have been or will be invested by industry over the next 5 to 10 years to develop the breeder and to build a demonstration plant. Five other nations--the United Kingdom, France, Japan, West Germany, and the Soviet Union--have a high priority national energy program for developing the LMFBR. These foreign breeder programs could contribute important data and information to the U.S. program

    With relation to the petroleum substitution energy in the U.K., the paper states measures taken for the development and introduction and the state of spread. Introduced were the U.K., energy policy described by energy field, petroleum and natural gas, coal, nuclear power, electric power, renewable energy (petroleum substitution energy), and the policy on energy conservation and the recent trend. Further, the paper took up the environmental policy relating to global warming which is an environmental problem in close connection with the energy industry and described the present status of exhaust gas such as acid rain gas and ozonospherial destruction gas, target for reduction of exhaust gas, and the present situation of exhaust gas at power plant. Explained were the positioning of and the measures for the petroleum substitution energy which was incorporated into a part of the energy policy in the U.K., especially the recent trend of obligation to use non-fossil fuel. First, the order of priority of the governmental policies was introduced, and then the NFFO order was described which was to give reliable fund base to the development toward the practical use of petroleum substitution energy. The paper also commented on recent topics on the state of the practical use of petroleum substitution energy. 2 figs., 7 tabs.

    2017-02-01

    We present in this work the development and experimental validation of a new piezoelectric material (V-Ink) designed for compatibility with projection stereolithography additive manufacturing techniques. Piezoelectric materials generate a voltage output when a stress is applied to the material, and also can be actuated by using an external voltage and power source. This new material opens up new opportunities for functional devices to be developed and rapidly produced at low cost using emerging 3D printing techniques. The new piezoelectric material was able to generate 115mV under 1N of strain after being polled at 80°C for 40 minutes and the optimal results had a piezoelectric coefficient of 105x10^(-3)V.m/N. The current iteration of the material is a suspension, although further work is ongoing to make the resin a true solution. The nature of the suspension was characterized by a time-lapse monitoring and through viscosity testing. The potential exists to further increase the piezoelectric properties of this material by integrating a mechanical to electrical enhancer such as carbon nanotubes or barium titanate into the material. Such materials need to be functionalized to be integrated within the material, which is currently being explored. Printing with this material on a "continuous SLA" printer that we have developed will reduce build times by an order of magnitude to allow for mass manufacturing. Pairing those two advancements will enable faster printing and enhanced piezoelectric properties.

    Emami, Hassan; Radfar, Reza

    2017-01-01

    The current situation in Iran suggests an appropriate basis for developing biotechnology industries, because the patents for the majority of hi-tech medicines registered in developed countries are ending. Biosimilar and technology-oriented companies which do not have patents will have the opportunity to enter the biosimilar market and move toward innovative initiatives. The present research proposed a model by which one can evaluate commercialization of achievements obtained from research with a focus on the pharmaceutical biotechnology industry. This is a descriptive-analytic study where mixed methodology is followed by a heuristic approach. The statistical population was pharmaceutical biotechnology experts at universities and research centers in Iran. Structural equations were employed in this research. The results indicate that there are three effective layers within commercialization in the proposed model.

    Immunomodulators are agents, which can modulate the immune response to specific antigens, while causing least toxicity to the host system. Being part of the modern vaccine formulations, these compounds have contributed remarkably to the field of therapeutics. Despite the successful record maintained by these agents, the requirement of novel immunomodulators keeps increasing due to the increasing severity of diseases. Hence, research regarding the same holds great importance. In this review, we discuss the role of immunomodulators in improving performance of various vaccines used for counteracting most threatening infectious diseases, mechanisms behind their action and criteria for development of novel immunomodulators. Understanding the molecular mechanisms underlying immune response is a prerequisite for development of effective therapeutics as these are often exploited by pathogens for their own propagation. Keeping this in mind, the present research in the field of immunotherapy focuses on developing immunomodulators that would not only enhance the protection against pathogen, but also generate a long-term memory response. With the introduction of advanced formulations including combination of different kinds of immunomodulators, one can expect tremendous success in near future.

  16. Biosynthesis of Oxytetracycline by Streptomyces rimosus: Past, Present and Future Directions in the Development of Tetracycline Antibiotics

    2017-01-01

    Full Text Available Natural tetracycline (TC antibiotics were the first major class of therapeutics to earn the distinction of ‘broad-spectrum antibiotics’ and they have been used since the 1940s against a wide range of both Gram-positive and Gram-negative pathogens, mycoplasmas, intracellular chlamydiae, rickett siae and protozoan parasites. The second generation of semisynthetic tetracyclines, such as minocycline and doxycycline, with improved antimicrobial potency, were introduced during the 1960s. Despite emerging resistance to TCs erupting during the 1980s, it was not until 2006, more than four decades later, that a third-generation TC, named tigecycline, was launched. In addition, two TC analogues, omadacycline and eravacycline, developed via (semisynthetic and fully synthetic routes, respectively, are at present under clinical evaluation. Interestingly, despite very productive early work on the isolation of a Streptomyces aureofaciens mutant strain that produced 6-demethyl-7-chlortetracycline, the key intermediate in the production of second- and third-generation TCs, biosynthetic approaches in TC development have not been productive for more than 50 years. Relatively slow and tedious molecular biology approaches for the genetic manipulation of TC-producing actinobacteria, as well as an insufficient understanding of the enzymatic mechanisms involved in TC biosynthesis have significantly contributed to the low success of such biosynthetic engineering efforts. However, new opportunities in TC drug development have arisen thanks to a signifi cant progress in the development of affordable and versatile biosynthetic engineering and synthetic biology approaches, and, importantly, to a much deeper understanding of TC biosynthesis, mostly gained over the last two decades.

    To explore the influence of risk factors present at Emergency Department admission on pressure ulcer development in trauma patients with suspected spinal injury, admitted to the hospital for evaluation and treatment of acute traumatic injuries. Prospective cohort study setting level one trauma center in the Netherlands participants adult trauma patients transported to the Emergency Department on a backboard, with extrication collar and headblocks and admitted to the hospital for treatment or evaluation of their injuries. Between January and December 2013, 254 trauma patients were included. The following dependent variables were collected: Age, Skin color and Body Mass Index, and Time in Emergency Department, Injury Severity Score, Mean Arterial Pressure, hemoglobin level, Glasgow Coma Score, and admission ward after Emergency Department. Pressure ulcer development during admission was associated with a higher age (p 0.00, OR 1.05) and a lower Glasgow Coma Scale score (p 0.00, OR 1.21) and higher Injury Severity Scores (p 0.03, OR 1.05). Extra nutrition decreases the probability of PU development during admission (p 0.04, OR 0.20). Pressure ulcer development within the first 48h of admission was positively associated with a higher age (p 0.01, OR 1.03) and a lower Glasgow Coma Scale score (p 0.01, OR 1.16). The proportion of patients admitted to the Intensive Care Unit and Medium Care Unit was higher in patients with pressure ulcers. The pressure ulcer risk during admission is high in patients with an increased age, lower Glasgow Coma Scale and higher Injury Severity Score in the Emergency Department. Pressure ulcer risk should be assessed in the Emergency Department to apply preventive interventions in time. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Nowadays, the market of medical tourism is considered as a revenue and competitive industry throughout the world, it is also regarded as a novel field of the sophisticated tourism. Therefore, most of the developing countries have focused on the medical tourism industry and they are planning for it. In 2016, the present research was conducted with the main objective of devising a pattern for medical tourism development in the West Azerbaijan Province. The statistical population consisted of all medical tourists who referred to the hospitals located in the province. With regard to the krejcie-morgan table and statistical population, the number of the sample was estimated to be equal to 260 persons. These persons were selected based on the multi-stage sampling method. The scholar made questionnaire and studies of the Ricafort and Kazemi were employed as the instrument of collecting data. The validity of questionnaire was confirmed by the experts, professors, supervising and advising professors after applying the required amendments. The reliability was realized using factor analysis method. The PLS method was utilized for analysis of the data. The findings indicate that %82.5 of the variations linked to the medical tourism development has been realized via changes in the two predictor variables (independent variable, including hospital selection and West Azerbaijan selection. Moreover, the two main factors, including hospital selection and West Azerbaijan selection with impact factors of 0.486 and 0.469, respectively have a direct and significant impact on the development of medical tourism of the province. West Azerbaijan Province has so many potentials, and due to this fact there exist very special conditions which can contribute to the development of the medical tourism industry in this region. It can be deduced that by carrying out measures, like creating a brand for province in the medical tourism field, coordination of the corresponding

    The paper describes the experience gained in Germany in applying burnup credit methodologies to wet storage and dry transport systems of spent LWR fuel. It gives a survey of the levels of burnup credit presently used or intended to be used, the regulatory status and future developments planned, the codes used for performing depletion and criticality calculations, the methods applied to verification of these codes, and the methods used to treat parameters specific of burnup credit. In particular it is shown that the effect of axial burnup profiles on wet PWR storage designs based on burnup credit varies from fuel type to fuel type. For wet BWR storage systems the method of estimating a loading curve is described which provides for a given BWR fuel assembly design the minimum required initial burnable absorber content as a function of the initial enrichment of the fuel.

  1. THE PRESENT CONDITION OF SMALL WATER RETENTION AND THE PROSPECTS OF ITS DEVELOPMENT USING THE EXAMPLE OF THE PODLASKIE VOIVODESHIP

    Directory of Open Access Journals (Sweden)

    Joanna Szczykowska

    2014-07-01

    Full Text Available The necessity and purposefulness of the investments related to water retention are justified mostly due to the preservation of the environment equilibrium as well as due to its farming, anti-flood, landscape and recreation aspects. Reasonable water management where various forms of retention are used gives large chances for the mitigation of the effects of unfavorable phenomena related to its insufficient amount. The creation of plans regarding the formation of reservoirs accumulating water is not necessarily synonymous with their realization. The reason of problems connected with the implementation of plans regarding the formation of new reservoirs lies mainly in financial measures and in problems with obtaining them. Water deficit in Poland is the reason for which the principles of its national usage need to be complied with. Realization of plans at both Voivodeship and municipality level that are focused on small retention will contribute to considerable increase in the retention capacity and will enable considerable increase in available resources in hydrographic catchments of both the characterized area and the entire country. The paper presents the characteristics of the present state and assumes the perspective development of small water retention in the Podlaskie Voivodeship using the example of the Podlaskie Voivodeship.

    2012-01-01

    Full Text Available Objective. To present an unusual but known cause of hypomagnesaemia induced-hypocalcaemia in a chronic GORD patient with severe symptoms with a review of the current literature. Methods. Analysis of the clinical and laboratory findings of the patient and discussion of the multi-factorial nature of his disease and the underlying mechanisms. Results. Our patient described features of magnesium deficiency such as weakness, muscle twitches, and fits with clinical signs of hypocalcaemia: a carpal pedal spasm and paraesthesia. Preadmission blood results revealed low calcium and magnesium levels. He was admitted to ITU, when he presented with seizures and developed encephalopathy. The total vitamin D level was 52.4 nmol/L (>49.9. His U&Es and LFTs were within the normal range with the exception of potassium. He was on Omeprazole for his GORD. With omission of the PPI 1 day after admission and replacement therapy, his ion levels normalised. Conclusion. Hypomagnesaemia is often undiagnosed and is associated with multiple biochemical abnormalities. Treatment focus should be aimed at stopping the PPI and replacing the magnesium. Over use of PPIs is a problem in practice, with the FDA issuing a warning over long-term use. Continued monitoring and decision making on dose reduction/withdrawal is essential to avoid complications.

    Developing competence in clinical skills is important if graduates are to provide entry-level care, but it is dependent on having had sufficient hands-on practice. Clinical skills laboratories provide opportunities for students to learn on simulators and models in a safe environment and to supplement training with animals. Interest in facilities for developing veterinary clinical skills has increased in recent years as many veterinary colleges face challenges in training their students with traditional methods alone. For the present study, we designed a survey to gather information from established veterinary clinical skills laboratories with the aim of assisting others considering opening or expanding their own facility. Data were collated from 16 veterinary colleges in North America and Europe about the uses of their laboratory, the building and associated facilities, and the staffing, budgets, equipment, and supporting learning resources. The findings indicated that having a dedicated veterinary clinical skills laboratory is a relatively new initiative and that colleges have adopted a range of approaches to implementing and running the laboratory, teaching, and assessments. Major strengths were the motivation and positive characteristics of the staff involved, providing open access and supporting self-directed learning. However, respondents widely recognized the increasing demands placed on the facility to provide more space, equipment, and staff. There is no doubt that veterinary clinical skills laboratories are on the increase and provide opportunities to enhance student learning, complement traditional training, and benefit animal welfare.

    Full Text Available The Middle to Late Neolithic transition in NE of Iberian Peninsula is characterized by changes in mortuary practices and grave goods. In the Middle Neolithic single primary burials are associated with grave goods of variscite beads, honey-colored flint blades and occasionally obsidian. During the Late Neolithic these are replaced for collective inhumations in cave and rock-shelters with grave goods composed mainly by shell, bone and stone beads and pendants, large flint blades and flint daggers, some from outside the Iberian Peninsula. Cova de l’Avi represents the earliest site (c. 4700 BP at which these changes in mortuary practice have been documented.Entre el Neolítico medio y el Neolítico final en el Nordeste de la Península Ibérica se producen cambios destacados en las pautas funerarias y en la cultura material de los grupos humanos, especialmente en los ajuares y lugares de enterramiento. Durante el Neolítico medio-reciente son típicas las inhumaciones primarias individuales en fosas con ajuares de cuentas de variscita, sílex melado, vasos cerámicos y puntualmente obsidiana. Por el contrario, durante el Neolítico final se generalizan las inhumaciones colectivas y sucesivas en cuevas y abrigos con ajuares que se caracterizan por la gran disminución de la variscita, sustituida por una gran variedad de colgantes y cuentas en piedra, concha y hueso. Ahora también aparecen las grandes láminas y los puñales de sílex, en ocasiones de procedencia extrapeninsular. La Cova de l’Avi representa en la actualidad el yacimiento cronológicamente más antiguo (c. 4700 BP en el que se documentan estos nuevos comportamientos funerarios.

    1992-10-01

    The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

    One of the greatest legacies of the International Polar Year (IPY) is the creation of APECS, the Association of Polar Early Career Scientists. As a grassroots effort, APECS was proposed, formed, and developed by and for early career polar researchers. While the young investigators who founded APECS had talent, ambition, and the desire to make things happen, partnerships with key organizations and experienced leaders in polar science were essential to provide the funding, leadership, and mentorship that has taken the organization well beyond the IPY and to over 2000 members. In four years, APECS has strived to foster the skills of and develop a group of early career interdisciplinary polar scientists through networking and mentoring among themselves and with senior scientists. Through diverse activities including, panel discussions, career development workshops, online seminars, a comprehensive job listing, formal mentoring, meeting travel support, and the APECS Virtual Poster Session, APECS goal is to support the early career researcher being trained to do the science, to become a well-rounded scientist prepared for 21st century careers in science. As part of that training, APECS members are encouraged to participate in activities and training related to science communication, education, and outreach; working with the media; participating in the science / public policy interface; and working with arctic communities and indigenous peoples. During the IPY, APECS members were guest speakers and presenters on International Polar Day activities; they contributed to resources for education and outreach such as the book: Polar Science and Global Climate: An International Resource for Education and Outreach; and they made connections with educators, community groups, the media through in-person presentations, blogs from the field, videos, and much more. Workshops, panels, and online discussions focusing on these activities helped develop the capacity to conduct such

    Ataxias are neurological disorders associated with the degeneration of Purkinje cells (PCs). Homozygous weaver mice (wv/wv) have been proposed as a model for hereditary cerebellar ataxia because they present motor abnormalities and PC loss. To ascertain the physiopathology of the weaver condition, the development of the cerebellar cortex lobes was examined at postnatal day (P): P8, P20 and P90. Three approaches were used: 1) quantitative determination of several cerebellar features; 2) qualitative evaluation of the developmental changes occurring in the cortical lobes; and 3) autoradiographic analyses of PC generation and placement. Our results revealed a reduction in the size of the wv/wv cerebellum as a whole, confirming previous results. However, as distinguished from these reports, we observed that quantified parameters contribute differently to the abnormal growth of the wv/wv cerebellar lobes. Qualitative analysis showed anomalies in wv/wv cerebellar cytoarchitecture, depending on the age and lobe analyzed. Such abnormalities included the presence of the external granular layer after P20 and, at P90, ectopic cells located in the molecular layer following several placement patterns. Finally, we obtained autoradiographic evidence that wild-type and wv/wv PCs presented similar neurogenetic timetables, as reported. However, the innovative character of this current work lies in the fact that the neurogenetic gradients of wv/wv PCs were not modified from P8 to P90. A tendency for the accumulation of late-formed PCs in the anterior and posterior lobes was found, whereas early-generated PCs were concentrated in the central and inferior lobes. These data suggested that wv/wv PCs may migrate properly to their final destinations. The extrapolation of our results to patients affected with cerebellar ataxias suggests that all cerebellar cortex lobes are affected with several age-dependent alterations in cytoarchitectonics. We also propose that PC loss may be regionally

    1 - The position of fast neutron reactors in the French nuclear energy program. In developing a program based on natural uranium, France will have an important stock of plutonium rich in higher isotopes. The existence of this plutonium and of the depleted uranium arising from the same reactors, has, as a logical consequence, the use of both in fast neutron reactors. Justified by this short term interest, the achievement of fast neutron reactors does, moreover, provide for a future necessity. 2 - Description of a fast neutron central power station of 1000 MWe. We indicate the characteristics of a future fast neutron central power station, plutonium fuelled, and sodium cooled. However uncertain these characteristics may be, they constitute a necessary guide in the orientation of our work. 3 - Studies carried out up to the present time. We give an outline of those studies, often very preliminary, which have given the characteristics cited above. The principal technical areas taken up are the following: - Neutronics (critical masses, breeding ratios, enrichments, flattening of the neutron flux, coefficients of reactivity, reactivity changes as a function of irradiation). - Dynamics, control, and safety. - Technology (design of the core and vessel, of the sodium system, and of the fuel handling mechanisms). These technical studies are complemented by economic considerations. The choice of the optimum characteristics is related to the existence of power production programs, and, in these programs, to the existence of plutonium producing thermal reactors. It is shown how, in this context, the existence of plutonium should be taken into account, and, in addition which mechanisms relate the economics of this plutonium to the choice of the most important parameters of the breeder reactors. 4 - Prototype reactor. The interest in an intermediate stage consisting of a reactor of a power level of about 80 MWe is justified. Its essential characteristics are briefly presented

    Suppressor of cytokine signalling (SOCS) family members are crucial in the control and attenuation of cytokine induced responses via activation of the JAK/STAT, TLR and NF-kB signalling pathways. SOCS proteins orchestrate the termination of many types of immune responses and are often the targets of microbial pathogens exploiting SOCS mechanisms to evade the host's immune response. Through whole and lineage specific genome duplication events, the teleost cytokine/SOCS network is complex. Not only are the orthologues of all mammalian SOCS members present, namely cytokine inducible Src homology 2 (SH2)-containing protein (CISH) and SOCS-1 to -7, but multiple gene copies exist that may potentially become functionally divergent. In this paper we focus on the CISH genes in rainbow trout (Oncorhynchus mykiss), and have cloned two further paralogues, CISHa2 and CISHb2, additional to the known CISHa1 and CISHb1 genes. We present for the first time a comparative expression analysis of these four paralogues, to establish whether subfunctionalisation is apparent. In vivo examination of gene expression revealed a higher constitutive expression level of CISHa paralogues compared to CISHb expression in adult trout tissues. All CISHs were relatively highly abundant in immune tissues but CISHa2 and CISHb2 had highest expression in the heart and muscle. An inverse picture of CISH abundance during trout ontogeny was seen, and further hints at differential roles of the four genes in immune regulation and development. Stimulation of head kidney (HK) leukocytes with trout recombinant interleukin (rIL)-15 and rIL-21 had a major effect on CISHa2 and to a lesser extent CISHa1 expression. In HK macrophages rIL-1β, phytohemagglutinin, and phorbol 12-myristate 13-acetate also had a strong impact on CISHa2 expression. Yersinia ruckeri infection caused a temporally and spatially differential onset of CISH expression that may be viewed in the context of pathogen evasion strategies. These data

    This paper is focused on the soft x-ray (SXR) tomography system setup at Tore Supra (DTOMOX) and the recent developments made to automatically get precise information about plasma features from inverted data. The first part describes the main aspects of the tomographic inversion optimization process. Several observations are made using this new tool and a set of shape factors is defined to help characterizing the emissivity field in a real-time perspective. The second part presents a detailed off-line analysis comparing the positions of the magnetic axis obtained from a magnetic equilibrium solver, and the maximum of the reconstructed emissivity field for ohmic and heated pulses. A systematic discrepancy of about 5 cm is found in both cases and it is shown that this discrepancy increases during sawtooth crashes. Finally, evidence of radially localized tungsten accumulation with an in-out asymmetry during a lower hybrid current drive pulse is provided to illustrate the DTOMOX capabilities for a precise observation of local phenomena.

    According to the IAEA Code of Practice on the subject and also to numerous national standards, effective quality assurance (QA) for safety in nuclear power plants depends upon the application of a number of fundamental principles. One of these principles is that QA for systems, components and structures should be commensurate with the individual importance to safety of each item. Evidently, money spent on excessive QA may be partly or wholly wasted, while too little QA will provide insufficient confidence that an item will perform satisfactorily in service. To deal successfully with the requirement of 'importance to safety', a detailed methodology must be established, by means of which QA can be prescribed rationally and consistently. Set in the context of the Canadian nuclear power and nuclear standards programmes, two related methodologies which account for importance to safety as well as for some other specific factors have been developed and are in use. These related methodologies are applied to the manufacture and installation of safety-related items, and are based on the implementation of the fixed-step, graded standards of the Canadian Standards Association, CSA Z299. Information is presented on the main features of the methodologies and on Canadian nuclear power plant QA practice in general. (author)

    The high temperature gas reactor has some features without previous reactors such as high temperature capable of taking-out, high specific safety, feasibility adaptable to versatile fuel cycle, and so on. Then, it is expected to be an innovative reactor to contribute to diversification of energy supply and expansion of energy application field. In Japan, under the HTTR (high temperature engineering test reactor) plan, construction of HTTR, which is the first high temperature gas reactor in Japan, was finished and its output upgrading test has been promoted. And, on the HTTR plan, together with promotion of full power operation, reactor performance tests, safety proof test, and so on, it is planned to carry out study on application of the high temperature heat such as hydrogen production and so on to aim to practise establishment and upgrading of technologies on high temperature gas reactor in Japan. Here were introduced features and present condition of development of the high temperature gas reactor as an innovative type reactor and described role and future scope in Japan. (G.K.)

    This paper is focused on the soft x-ray (SXR) tomography system setup at Tore Supra (DTOMOX) and the recent developments made to automatically get precise information about plasma features from inverted data. The first part describes the main aspects of the tomographic inversion optimization process. Several observations are made using this new tool and a set of shape factors is defined to help characterizing the emissivity field in a real-time perspective. The second part presents a detailed off-line analysis comparing the positions of the magnetic axis obtained from a magnetic equilibrium solver, and the maximum of the reconstructed emissivity field for ohmic and heated pulses. A systematic discrepancy of about 5 cm is found in both cases and it is shown that this discrepancy increases during sawtooth crashes. Finally, evidence of radially localized tungsten accumulation with an in–out asymmetry during a lower hybrid current drive pulse is provided to illustrate the DTOMOX capabilities for a precise observation of local phenomena.

    We demonstrate a novel optical coherence tomography system specifically developed and validated for clinical imaging of retinoblastoma tumors in pediatric patients. The existing treatment options for this malignant tumor of the retina aim at reduction of tumor (re)growth risks, and vision preservation. The choice of optimal treatment strongly depends on skilled and detailed clinical assessment. Due to the limitations of the existing real-time diagnostic tools the patients at risk are periodically monitored with retinal imaging to confirm the absence of new tumor seedings. Three-dimensional visualization of tissue layer and microvasculature at improved axial and lateral resolution of interference-based OCT imaging provides sensitivity for detection of vital tumor tissue concurrent with local treatment. Our METC-approved system accommodates for the range of optical parameters of infants' eyes, and uses the 1050nm wavelength to access the deeper choroid layers of retina. The prototype is designed for patients in supine position under general anesthesia, where ergonomic handheld module is connected to fiber-based optical setup via umbilical cord. The system conforms to clinical safety requirements, including fully isolated low-voltage electric circuit. Focusing is performed with a mechanically tunable lens, where resolution is 6 µm axially, and varies with focusing at 10-18µm laterally. We will present optical design, performance limitations, and results of the ongoing clinical study, including the increased OCT diagnostic sensitivity in three dimensions in comparison with the established clinical imaging modalities. We will discuss images of early, active, and treated tumors, as well as follow-up on patients after local and systemic treatments.

Accumulation of the glycosaminoglycans dermatan sulfate and heparan sulfate results in a broad range of disease manifestations that are highly variable in presentation and severity; notably, approximately two-thirds of individuals are affected by progressive central nervous system involvement. Historically, management of this disease was palliative; however, during the 1990s, I2S was purified to homogeneity for the first time, leading to cloning of the corresponding gene and offering a means of addressing the underlying cause of MPS II using enzyme replacement therapy (ERT. Recombinant I2S (idursulfase was produced for ERT using a human cell line and was shown to be indistinguishable from endogenous I2S. Preclinical studies utilizing the intravenous route of administration provided valuable insights that informed the design of the subsequent clinical studies. The pivotal Phase II/III clinical trial of intravenous idursulfase (Elaprase®; Shire, Lexington, MA, USA demonstrated improvements in a range of clinical parameters; based on these findings, intravenous idursulfase was approved for use in patients with MPS II in the USA in 2006 and in Europe and Japan in 2007. Evidence gained from post-approval programs has helped to improve our knowledge and understanding of management of patients with the disease; as a result, idursulfase is now available to young pediatric patients, and in some countries patients have the option to receive their infusions at home. Although ERT with idursulfase has been shown to improve somatic signs and symptoms of MPS II, the drug does not cross the

    There is an important link between platelets and inflammation, thrombosis, and vascular and tissue repair mechanisms. SCUBE1 (signal peptide-CUB-EGF domain-containing protein 1) may function as a novel platelet-endothelial adhesion molecule and play pathological roles in cardiovascular biology. Stent thrombosis (ST) following percutaneous coronary intervention is an uncommon and potentially catastrophic event that can manifest as myocardial infarction and sudden death. High platelet reactivity is a risk factor for thrombotic events, including late ST. For this reason, in the current study, we researched the role of SCUBE1 in the development of late coronary ST. We included 40 patients admitted to our hospital with a diagnosis of ST-elevation myocardial infarction (STEMI) and signs of late ST on a coronary angiogram. For the control group, we recruited 50 healthy gender- and age-matched individuals who were seen for health check-ups. We also randomly included 100 patients with a diagnosis of STEMI without ST. There were no significant differences between the groups in terms of baseline and demographic characteristics. The mean SCUBE1 level in patients with STEMI with late ST at admission and the STEMI without ST group was significantly higher than in the control group (pST group was significantly higher than in the STEMI without ST group (p=0.03). In multivariate regression analysis, serum SCUBE1 (odds ratio [OR]: 1.022; 95% confidence interval [CI]: 1.011-1.033, pST. In addition, receiver operating characteristic curve analysis was used to determine the optimal SCUBE1 cut-off value for predicting late ST. The area under the curve was 0.972 (95% CI 0.95-0.98). The SCUBE1 cut-off value was 59.2 ng/ml, with a sensitivity of 95.4% and specificity of 82.9%. The present work is the first clinical study to demonstrate that serum SCUBE1 levels are significantly higher in patients with late ST and serum SCUBE1 was an independent predictor for the presence of late ST in our

    1996-03-01

    The paper investigates and reports the trend of the development of petroleum substitution energy in the U.S. The Clean Coal Technology Plan is one of the plans which were implemented most successfully in the past several years. The plan made a remarkable reduction in NOx and SOx emissions possible. As for natural gas, importance is placed on improvement of production/storage technology of natural gas and high-effective low-NOx-emission turbines. As to the research on nuclear reactors, importance is now placed on the light water reactor plan, and the target is the design and development of such nuclear reactors as electric power companies pay attention to. The solar cell industry is markedly developing, and the shipment grows 17% per year. However, the price is rapidly declining. The wind turbine and biomass power generation plans are also advanced, and most of the plans are aimed at the development of new fields of application. With regard to geothermal energy, slowness is seen. Concerning electric vehicles, no makers enter into the quantity production, but the research and development are actively being made. 72 refs., 26 figs., 51 tabs.

    The discoveries and inventions made over the last two decades have substantially enlarged the scope of contacts between man and sources of ionizing radiation. Scientific developments raising energy yield from nuclear processes have been reflected in a growing nuclear power industry as well as expanding use of radioactive substances or radiation sources in various areas of human endeavor, and have become a potent factor in technological progress, mechanization and automation. No such tempestuous expansion of applications of nuclear physics achievements would have been possible without the concurrent development and further synchronous advances in relevant fields of health science, with research achievements promptly introduced into sanitary supervision practice. The paper summarizes major results of research in radiation hygiene; outlines the impact of their application to sanitary supervision practice in principal operational sectors; identifies and motivates further lines of injury as well as prospects for developing up-to-date supervision schemes and for reasonable unification of measurement and monitoring techniques.

    There had been many reports about cardiac complications of patients with Hodgkin`s disease (HD) after cessation of treatment in Europe and the United States. However, cases of HD accompanied with these complications were extremely rare in Japan. We report a case with HD that developed a cardiac tamponade during the clinical course of chemotherapy and showed a pancytopenia after cessation of chemotherapy. The case was a 14 year-old boy with HD (nodular sclerosis) of anterior upper mediastinum origin. He received modified MOPP therapy and irradiation to the semimantle field and to the mediastinum. The total dose of radiation was 36.3 Gy. He suddenly developed a chest pain, chest discomfort, and dyspnea during the sixth course of chemotherapy. He was diagnosed to have a cardiac tamponade by thoracentesis. The symptoms were improved by continuous transcutaneous drainage. The invasion of HD into the effusion was not detected by cytology, and the chemotherapy was completed after one course. However, he gradually developed a macrocytic anemia and finally developed a pancytopenia. The bone marrow specimen revealed a hypoplasia without evidence of pathological cells. The karyotype of marrow derived cells was normal. With oxymetholone administration, the pancytopenia has improved in four months. He has now been doing well for five years after the cessation of therapy. (author)

    Since 1974 a variable energy isochronous cyclotron (CV-28) is operating at Instituto de Engenharia Nuclear in Rio de Janeiro, with the main purpose of producing radioisotopes for medical diagnosis. To accomplish this, besides the conventional chemical laboratories and related facilities, hot chemistry laboratories with their specific equipment and remote handling devices had to be designed and constructed at this Institute, and are still being developed, due to a lack of engineering companies working in this field. Other equipment, intrinsically related to cyclotrons like high power density target holders, collimators etc. were also conceived and constructed. Among the produced raioisotopes, high purity gallium-67 and indium-111 have been periodically sent to hospitals and some efforts are still being made in order to improve and simplify the chemical processing as well as the operational procedures. Some work has also been devoted to the development and improvement of methods for the production of iodine-123, bromine-77 and thallium-201. (Author) [pt

    1996-03-01

    The paper investigates and reports the developmental trend of petroleum substitution energy in Germany. Policies for the technical development and actual introduction of petroleum substitution energy in Germany are concerned with three energies: coal, natural gas, and new energy, except nuclear energy the use of which is against public opinion. Coal is the only abundant domestic resource, but not internationally competitive because of its cost. Brown coal obtained from the open pit mining is an abundant and low-cost domestic resource, but has the environmental problem. The latest technology is actually being introduced in which the thermal power generation is integrated into gasification, and the gas/steam turbine power generation. Natural gas is advancing in the use as energy source for space heating substituting for brown coal. The technology development of new energy is promoted mainly on such wind power and solar energy as are called renewable energy. As to the development of technology using renewable energy for which the rapid increasing use is not expected in near future, the target is directed mostly to CO2 control and the third world where there are no public electric power nets. 30 refs., 10 figs., 8 tabs.

  15. Development of an optimized algorithm for the characterization of microflow using speckle patterns present in optical coherence tomography signal

    Pretto, Lucas Ramos de

    2015-01-01

    This work discusses the Optical Coherence Tomography system (OCT) and its application to the microfluidics area. To this end, physical characterization of microfluidic circuits were performed using 3D (three-dimensional) models constructed from OCT images of such circuits. The technique was thus evaluated as a potential tool to aid in the inspection of microchannels. Going further, this work paper studies and develops analytical techniques for microfluidic flow, in particular techniques based on speckle pattern. In the first instance, existing methods were studied and improved, such as Speckle Variance - OCT, where a gain of 31% was obtained in processing time. Other methods, such as LASCA (Laser Speckle Contrast Analysis), based on speckle autocorrelation, are adapted to OCT images. Derived from LASCA, the developed analysis technique based on intensity autocorrelation motivated the development of a custom OCT system as well as an optimized acquisition software, with a sampling rate of 8 kHz. The proposed method was, then, able to distinguish different flow rates, and limits of detection were tested, proving its feasibility for implementation on Brownian motion analysis and flow rates below 10 μl/min.

    2001-01-01

    A number of reactor concepts are being advanced worldwide also in the light of long-term perspectives in the power economy. Activities in this respect are concentrated on the proven technologies of light-water and heavy-water reactors and on gas or liquid-metal cooled designs. Also smaller units are being considered for various applications. Framatome ANP focus on further development of the EPR and SWR 1000 light-water reactor lines. These plant concepts, which were developed in cooperation with, and with the support of, power utilities together with a number of European partners, are characterized by an even higher level of safety, especially as far as potential accidental releases are concerned, and by their competitiveness in the electricity generating market compared to other sources of energy. Given the cost structure of these plants, with approx. 60% capital costs, approx. 24% operating costs, and approx. 16% fuel cycle costs, efforts are made in particular to reduce the dominating capital cost share. For the EPR, this is to be achieved by high plant capacities, i.e. lower specific capital outlays per kilowatt installed; for the SWR 1000, mainly by means of an optimized, streamlined plant design. Moreover, installed nuclear generating capacities provide long-term assurance in calculating electricity generating costs, as they are less sensitive to the variable costs of the fuel cycle and of operation than fossil-fired plants. Commercial maturity of the SWR 1000 will be achieved after the completion of basic development in late 1999 and the ongoing detailed design steps in 2001. Also for the EPR, commercial maturity has been achieved with the completion of the basic design phase. (orig.) [de

    In view of the urgent need for superconductivity in the next generation of big fusion devices and the identified gap between aimed data and the state of the art, impressive development programs are running world-wide, e.g. the IEA-Large Coil Task (LCT) and magnets for near term experiments (T15, Tore Supra). During the development work for all these magnet systems and simultaneously running design studies, especially the INTOR-study, some critical problem areas, e.g. concerning NbTi-conductor design and manufacturing and coil fabrication could be solved, others like the limitations by fatigue stresses for coil case and support structure turned out to be more stringent than anticipated. This paper tries to show which plasma physics parameters place especially severe constraints to magnet design, like PF-pulse number and amplitude at the TF-coils, so that they should be chosen with strongest care. It further points out which technologies under these circumstances are still missing or unproven with respect to the INTOR-like generation of fusion experiments. Further effort is mainly required for fatigue load behaviour of materials and components, high field windings and poloidal field coils. (author)

High efficiency and operation reliability in a power range noticeably higher than already mastered level are required. In design of the accelerators basic units, namely, HV generators, accelerating structures, electron beam irradiation field forming systems and extraction devices solutions that demonstrated already theirs operational capacity in the machines of a lesser power may be used. From the other hand, experience gained by already full-scale built powerful installations shows that a number of problems remain unsolved that put obstacles on a way of wide implementation of exhaust gases irradiation processing. Attempts to built the accelerator meeting all requirements in a frame of specific contracts, although already shown noticeable progress in a sense of the power grow, acquiring of very valuable experience, carry some risk caused by insufficient study of the problems connected with power increasing, lack of time and means for the thorough research works. It looks reasonable to suggest creation of full-scale pilot installation with HV accelerator of required power (1 MW, for example) not bound to a specific commercial contract, where researches and studies of the accelerator main systems, theirs optimization and longevity tests can be carried out thus providing development of the accelerator into really reliable and effective tool for applying to environmental tasks.

    The elaboration of a mutagenic potential scale (MPS) will be accomplished through the evaluation of the frequency of induced mutations in a plant biological system in different sites. The selection of these sites will be based on general public perception of risk to health. In this selection, it will include areas such ecological paradises and also neighborhoods of nuclear reactors and uranium mining and milling industry with potential radiological impact. The developed project foresees the contribution of other research groups that will also provide data from different sites. The referred scale will be built based on the response of the genetic system that gives color to the cells of Tradescantia (BNL 4430) stamen hair to mutagenic agents. Methodological improvements has been developed aiming the computerization of mutagenic events evaluation and statistical analysis of data that will significantly increase the efficiency of the system and obtention of results. Other biological systems of environmental quality are being added to the project, for future use. MPS should facilitate the general public and professionals of the nuclear area to understand risks, on a biological basis, of exposure from radiologically impacted environments. (author)

    Far-infrared light sources are being developed with a 38-MeV L-band linear accelerator at the Institute of Scientific and Industrial Research, Osaka University. In the experiments of free-electron laser the self-amplified spontaneous emission was observed at wavelengths of 20 and 40 {mu}m with a high-intensity single-bunch beam for a single passage through a wiggler. In the free-electron laser oscillation experiments with a multibunch beam laser light was obtained at wavelengths from 32 to 40 {mu}m. The peak power in a micropulse of the laser was estimated to be 8.3 MW at a wavelength of 40 {mu}m. Coherent radiation emitted from bunched electrons was observed for Cherenkov and transition radiation processes with the single-bunch beam. (author)

    Particle beam therapy (PBT), including proton and carbon ion therapy, is an emerging innovative treatment for cancer patients. Due to the high cost of and limited access to treatment, meticulous selection of patients who would benefit most from PBT, when compared with standard X-ray therapy (XRT), is necessary. Due to the cost and labor involved in randomized controlled trials, the model-based approach (MBA) is used as an alternative means of establishing scientific evidence in medicine, and it can be improved continuously. Good databases and reasonable models are crucial for the reliability of this approach. The tumor control probability and normal tissue complication probability models are good illustrations of the advantages of PBT, but pre-existing NTCP models have been derived from historical patient treatments from the XRT era. This highlights the necessity of prospectively analyzing specific treatment-related toxicities in order to develop PBT-compatible models. An international consensus has been reached at the Global Institution for Collaborative Research and Education (GI-CoRE) joint symposium, concluding that a systematically developed model is required for model accuracy and performance. Six important steps that need to be observed in these considerations include patient selection, treatment planning, beam delivery, dose verification, response assessment, and data analysis. Advanced technologies in radiotherapy and computer science can be integrated to improve the efficacy of a treatment. Model validation and appropriately defined thresholds in a cost-effectiveness centered manner, together with quality assurance in the treatment planning, have to be achieved prior to clinical implementation.

    Introduction: Research in the field of biological effects of heavy charged particles is necessary for both heavy-ion therapy (hadrontherapy) and protection from the exposure to galactic cosmic radiation in long-term manned space missions.[Durante M. 2004] In future crew of long-term manned missions could operate in exremely high hadronic radiation areas of space and will not survive without effective radiation protection. An Antiradiation Vaccine (AV) must be an important part of a countermeasures regimen for efficient radiation protection purposes of austronauts-cosmonauts-taukonauts: immune-prophylaxis and immune-therapy of acute radiation toxic syndromes developed after heavy ion irradiation. New technology developed (AV) for the purposes of radiological protection and improvement of radiation tolerance and it is quite important to create protective immune active status which prevent toxic reactions inside a human body irradiated by high energy hadrons.[Maliev V. et al. 2006, Popov D. et al.2008]. High energy hadrons produce a variety of secondary particles which play an important role in the energy deposition process, and characterise their radiation qualities [Sato T. et al. 2003] Antiradiation Vaccine with specific immune-prophylaxis by an anti-radiation vaccine should be an important part of medical management for long term space missions. Methods and experiments: 1. Antiradiation vaccine preparation standard, mixture of toxoid form of Radiation Toxins [SRD-group] which include Cerebrovascular RT Neurotoxin, Cardiovascular RT Neurotoxin, Gastrointestinal RT Neurotoxin, Hematopoietic RT Hematotoxin. Radiation Toxins of Radiation Determinant Group isolated from the central lymph of gamma-irradiated animals with Cerebrovascular, Cardiovascular, Gastro-intestinal, Hematopoietic forms of ARS. Devices for radiation are "Panorama", "Puma". 2. Heavy ion exposure was accomplished at Department of Research Institute of Nuclear Physics, Dubna, Russia. The heavy ions

    The US radon measurement programme began in the late 1950s by the US Public Health Service in Colorado, New Mexico and Utah during the uranium frenzy. After the 1967 Congressional Hearings on the working conditions in uranium mines, the US Atomic Energy Commission (AEC) was asked to conduct studies in active uranium mines to assess the exposure of the miners on the Colorado Plateau and in New Mexico. From 1967 to 1972, the Health and Safety Laboratory of the US AEC in New York investigated more than 20 uranium mines for radon and radon decay product concentrations and particle size in 4 large uranium mines in New Mexico. In 1970, the US Environmental Protection Agency (EPA) was established and took over some of the AEC radon measurement activities. Between 1975 and 1978, the Environmental Measurements Laboratory of the US Department of Energy conducted the first detailed indoor radon survey in the USA. Later in 1984, the very high concentrations of radon found in Pennsylvania homes set the wheels in motion and gave birth to the US Radon Industry. The US EPA expanded its involvement in radon issues and assumed an active role by establishing the National Radon Proficiency Program to evaluate the effectiveness of radon measurement and mitigation methods. In 1998, due to limited resources EPA privatised the radon programme. This paper presents a personal perspective of past events and current status of the US radon programme. It will present an update on radon health effects, the incidence rate of lung cancer in the USA and the number of radon measurements made from 1988 to 2013 using short-term test methods. More than 23 million measurements were made in the last 25 y and as a result more than 1.24 million homes were mitigated successfully. It is estimated that USA are made using long-term testing devices. The number of homes above the US action level of 148 Bq m(-3) (4 pCi l(-1)) may be ∼8.5 million because ∼50 million homes were added since 1990 to the home

    Coordination among the different stakeholders at policy planning, implementation and target beneficiary level, particularly among the agencies responsible for development and management of water resources, agriculture and fisheries, is essential for overall sustainable development. Stocking of larger fingerlings at suitable stocking densities of endemic (rohu, catla, mrigal) and exotic (silver carp, bighead carp, common carp/mirror carp) species should be stocked at varying proportion. Floodplain fish production depends only on the natural fertility of the water bodies. Technological interventions should include the installation of low cost bamboo fencing at water inlet and outlet points and setting of ring culverts for maintaining suitable levels of water for fish culture without hampering the production of rice and other crops in the intervention areas, selective stocking with native and exotic carps, restricted fishing for certain period of time and guarding. It is expected to exert positive influences in enhancing the standing crop and biodiversity of non-stocked species of fishes in the intervention seasonal floodplain. Entry of fish larvae, hatchlings and young fry of wild non-stocked fishes into the seasonal floodplains because of large fence spacing (approximately 1.0 cm), could restrict fishing for certain period, undisturbed habitat and guarding could contribute to higher productivity and enhancement of fish biodiversity in the seasonal floodplains. Proper motivation and effective cooperation of the beneficiaries are extremely important to culture fish in the seasonal floodplains under community based management system. Institutional support and constant vigilance from the Department of Fisheries (DoF) and local administrations are indispensable to ensure the sustainability of fish culture initiatives in the seasonal floodplains. Active participation and involvement of the local community people in all stages of fish culture operation beginning from

    PPC is by far the major producer of solid fuels in Greece. Currently the known exploitable reserves of solid fuels, are 4,0 billions tones of lignite and 4 billion cubic meters of peat. Mining of Lignite in Greece started in 1951 at the Aliveri underground mine and was continued at the open cast mines at Ptolemais (1955) and Megalopolis (1919). For more than 45 years. PPC has successfully exploited the Greece Lignite deposit for the production of electricity in order to satisfy the demand in Greece. Today PPC produces 60 million tons of lignite and handles approximately 275 million cubic meters of masses (overburden, lignite and interculated) per year. Lignite is the main energy resource in Greece and its combustion provides 75-80% of the electrical energy consumed in Greece.The Lignite Center of Ptolemais - Amyndeon (LCP-A) operated by the Greece PPC is located in northern Greece, about 110 km west of the city of Thessaloniki. The lignite deposits under exploitation cover an area. of 120 km 2 including 4000 Mt of proven geological reserves and 2700 Mt of exploitable lignite under current economic and technological criteria. Today LCP-A manages six active mines which in 1997 have a rate of handling 245 mil cubic meter of material and producing approx. 48 mil for of lignite. The continuous mining method which employs BWES, conveyors and strackers is the principal mining method used in all the lignite mines at the Ptolemais-Amyndeon Lignite Center. The implementation of selective mining procedures as well as discontinuous and /or combined mining methods differentiates the mining technology at the LCP-A from the respective technology applied in Germany lignite mines. The quality properties suggest that the lignite deposits in Greece are among the world's worst quality deposits exploited for energy production, where approximately 2 kg of lignite are consumed per I kWh of generated power. The main advantages of PPC'S coal orientated development program are the following

    New editions of the original Gamma-ray Spectrum Catalogues are being prepared for publication in electronic format. The objective of this program is to produce versions of the Catalogues in CD-ROM format and as an Internet resource. Additions to the original content of the Catalogues will include integrated decay scheme drawings, tables of related decay data, and updated text on the techniques of gamma-ray spectrometry. Related decay data from the Evaluated Nuclear Structure Data File (ENSDF) are then added, and all data converted to the Adobe Acrobat (PDF) format for CD-ROM production and availability on the large-volume Ge detectors, alpha-particle spectra, prompt neutron capture and inelastic scattering gamma-ray spectra, and gross fission product spectra characteristic of fuel cycle waste materials. Characterization of radioactivity in materials is a requirement in many phases of radioactive waste management. Movement, shipping, treatment, all activities which involve handling of mixed waste or TRU categories of waste at all DOE sites will require that measurements and assessment documentation utilize basic nuclear data which are tracable to internationally accepted standard values. This program will involve the identification of data needs unique to the development and application of specialized detector systems for radioactive waste characterization. 8 refs., 8 figs.

    Of environmental stresses, salinity has negative impacts on agricultural yield throughout the world; affected production is 1% as compared to 3%. Soil salinity affects plant growth and development by way of osmotic stress, injurious effects of toxic Na/sup +/ and Cl/sup -/ ions and to some extent Cl/sup -/ and SO/sub 4//sup 2-/ of Mg//sup 2+/. The plant response to salinity consists of numerous processes that must function in coordination to alleviate both cellular hyper osmolarity and ion disequilibrium. However, cell biology and molecular genetics research is providing new insight into the plant response to salinity and is identifying genetic determinants involved in the salt tolerance. Recent confirmation (Arabidopsis thaliana) to salt tolerance determinants is that mediate cellular ion homeostasis. The transport systems facilitate cellular capacity to utilize Na/sup +/ for osmotic adjustment and growth and the role of the Salt-Overly-Sensitive (SOS) signal transduction pathway in the regulation of ion homeostasis and salt tolerance. The SOS signaling pathway regulates Na/sup +/ and K/sup +/ homeostasis, after Ca/sup 2+/ activation. Furthermore, overexpression of AtNHX1 enhances plant salt tolerance, presumably by increasing vacuolar Na/sup +//H/sup +/ compartmentalization that minimizes the toxic I. accumulation of the ion in the cytosol. The activation of SOS1 (Na/sup +/ efflux) and/or AtNHX1 (Na/sup +/ efflux) so by expression of such transporters enhances salt tolerance in plants. (author)

    Full text: Transference of explicit knowledge starts from content development, and proceeds with packaging and delivery. A comparative study of some selected authoring tools for knowledge creation in Nuclear Sciences and Engineering education is being carried out at the School of Nuclear and Allied Sciences in Accra, Ghana. These authoring tools include commercial software (Macromedia Suite CS6, Learning 6.0) as well as freeware software (Xerte, eXe). A course, X-ray Fluorescence Spectrometry (NSAP 603), at the postgraduate School of Nuclear and Allied Sciences (SNAS), has been selected for migration onto an eLearning platform. Different authoring tools have been employed to create some ICT-based modules for teaching and learning. This paper therefore shares the experiences realized in moving from course syllabus to digitized modules, integrating pedagogical considerations, the strengths and weakness of the selected authoring tools, user-interactivity and usability of the modules produced. The need and the basis for the adoption of an appropriate authoring tool for creation of scientific, mathematical, and engineering documents and learning materials has also been discussed. Leveraging on ICT to produce pedagogically sound learning materials for eLearning platforms promotes interests of students in nuclear sciences, and ensures continuity in producing qualified professionals.

    An important part of the workshop was a series of invited presentations. The presentations were intended to both provide the participants with an understanding of various organisational approaches and activities as well as to stimulate the exchange of ideas during the small group discussion sessions. The presentation subjects ranged from current organisational regulations and licensee activities to new organisational research and the benefits of viewing organisations from a different perspective. There were more than a dozen invited presentations. The initial set of presentations gave the participants an overview of the background, structure, and aims of the workshop. This included a short presentation on the results from the regulatory responses to the pre-workshop survey. Representatives from four countries (Sweden, Canada, Finland, and the United Kingdom) expanded upon their survey responses with detailed presentations on both regulatory and licensee safety-related organisational activities in their countries. There were also presentations on new research concerning how to evaluate safety critical organisations and on a resilience engineering perspective to safety critical organisations.

Many host countries give victims of torture the status of refugee and take care of them as far as basic needs; health care, professional reinsertion, and education. Little is known about the costs of torture. However, this knowledge could serve as an additional argument for the prevention and social mobilization to fight against torture and to provide a powerful basis of advocacy for rehabilitation programs and judiciary claims.Objectives: Development of a model for estimating the economic costs of torture and applying the model to a specific country.Methods: The estimation of the possible prevalence of victims of torture was based on a review of the literature. The identification of the socioeconomic factors to be considered was done by analogy with various health problems. The estimation of the loss of the productivity and of the economic burden of disease related to torture was done through the human capital approach and the component technique analysis.Case study: The model was applied to the situation in Switzerland of estimated torture victims Switzerland is confronted with.Results: When applied to the case study, the direct costs – such as housing, food, and clothing – represent roughly 130 million Swiss francs (CHF per year; whereas, health care costs amount to 16 million CHF per year, and the costs related to education of young people to 34 million CHF per year. Indirect costs, namely those costs related to the loss of the productivity of direct survivors of torture, have been estimated to one-third of 1 billion CHF per year. This jumps to

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    Full Text Available Dear Readers, It is with great satisfaction and sense of responsibility that I hand over to our community the third issue of Volume 11 of Internext, the first one in which I was the editor-in-chief. Last October, the Program of Master's and Doctoral Program in International Management (PMDGI coordination, giving continuity to the rotation policy of editors, assigned me the function. My satisfaction and a sense of responsibility are heightened by the fact that Anpad has recently released a new Spell ranking of national academic journals based on their impact factors, and in that ranking Internext is  in the first quartile among the 97 ranked journals. In the criterion of citations per document, Internext ranked 4th among all Brazilian Business journals! Of course, the merit of the impact of Intenext, evidenced by the Spell classification, does not belong to the publisher who just took office, but to those who preceded me: Felipe Borini and Eduardo Spers. To both of them, and the rest of the editorial team, especially the never tiring  Dennys Rosseto and Jackeline Ferreira, my recognition for their  dedication and competence and my commitment to do everything within my reach to maintain and evolve the quality of the work that have done. In this issue, as in the previous ones, Internext features  six articles that constitute important additions to the stock of knowledge about internationalization of business in emerging countries. In a context of intense discussion of the implications of protectionist measures for national industries, Yolanda Carbajal-Suárez and María Esther Morales-Fajardo carry out a timely analysis of the development of the automotive sector in Brazil and Mexico, with an emphasis on the impact of trade agreements negotiated between the two governments on export and competitiveness of these sectors.

    2017-01-01

    Full Text Available The development of theoretical provisions of economic security, their mechanisms and instruments is determined by the laws of the economy that reveal the management of production, the market processes of distribution, exchange, consumption, taking into account the features of industries, regions, the level of globalization, etc. Each sphere, region or branch of the economy is characterized by peculiar economic processes justified by a specific approach to their disclosure. Economic security, its emergence, development and adaptation to changing market conditions, is based on the information economy or on the knowledge economy. Economic security is determined by the costs of information, its confidentiality, taking into account the interaction, on the one hand, and the competition of various enterprises, regions and countries, on the other. In the process of economic development, knowledge in general and any specialists are needed, but only those that are necessary in the economy. Communication and interaction of science, knowledge, information with production provides not only economic security, but also their successful development. To develop certain principles or laws for the interaction of technological and economic factors, their degree and level of interaction, a study of economic activity was conducted. In the present study, a civilizational approach was used that is based on the determining role of man in the economy and society and the importance of knowledge and information, when the important mechanisms remain: the development of technology and technology, the role of knowledge and information, and communication. The implementation of the civilized approach takes into account the new methodological level of increasing economic security, when the main factor in the development of the economy is the scientific and technological progress that justifies the information path of economic development.

    This report of the French National Assembly first presents the different programmes and actions related to energy and industry for which credits are foreseen in the French finance bill for 2010: development of firms and employment, energy policy, after-mining policy, struggle against climate change, management of ecology, energy, sustainable development, and sea policies, research in the field of energy and sustainable development and planning. The author then outlines the importance of the creation of conditions for a green growth in order to cope with an unprecedented crisis which ruins industrial employment. This implies the support of strategic sectors (energy-efficient building, evolution towards green chemistry, photovoltaic solar energy, renewable heat, innovating vehicles), the implementation of new priorities (smart grids, management of raw materials), and the emergence of ecological technologies promoted by the new tools of a climate policy (carbon tax introduction, improvement of carbon markets). It also implies an industrial output for research by means of a networking of actors (development of competitiveness poles, participation to European partnerships), and a reinforcement of the industrial horizon in the research policy (patenting, start-up development, support to innovating small and middle-sized companies, implementation of a true French capital-risk sector)

    The wide spread of digital technology in the medical field has led to a demand for the high-quality, high-speed, and user-friendly digital image presentation system in the daily medical conferences. To fulfill this demand, we developed a presentation system for radiological and pathological images. It is composed of a super-high-definition (SHD) imaging system, a radiological image database (R-DB), a pathological image database (P-DB), and the network interconnecting these three. The R-DB consists of a 270GB RAID, a database server workstation, and a film digitizer. The P-DB includes an optical microscope, a four-million-pixel digital camera, a 90GB RAID, and a database server workstation. A 100Mbps Ethernet LAN interconnects all the sub-systems. The Web-based system operation software was developed for easy operation. We installed the whole system in NTT East Kanto Hospital to evaluate it in the weekly case conferences. The SHD system could display digital full-color images of 2048 x 2048 pixels on a 28-inch CRT monitor. The doctors evaluated the image quality and size, and found them applicable to the actual medical diagnosis. They also appreciated short image switching time that contributed to smooth presentation. Thus, we confirmed that its characteristics met the requirements.

    A method was developed for determining the location of activity present in 200 litre waste drum using USB based MCS system coupled to a segmented gamma ray scanner. 137 Cs source was kept at various distances from centre of the drum along the axis of the detector. Drum was rotated and the activity profiles were determined as a function of angle of rotation. The plot of the count rate as a function of angle of rotation was found to have two peaks. The experimental and calculated data were found to match well at all angles. Present studies have shown that the ratio of height and width of the profile at angles of 0 ° and 180° can be used to determine the location of the activity in the drum. (author)

    Full text: Software of data logging and graphical presentation on gamma scanning for trouble shooting and process evaluation of the petroleum refinery column was developed. While setting the gamma source and gamma detector at the opposite orientation along side the column and recording the transmitted radiation through the column at several elevations, the relative density gamma intensity vs. vertical elevation could be obtained in the graphical mode. In comparison with engineering drawing, the physical and process abnormalities could be clearly evaluated during field investigation. The program could also accumulate up to 8 data sets, each of 1,000 points allowing with convenience, the comparison of different operational parameters adjustment during remedy of the problem and/or process optimization. Incorporated with this development and other factors, the technology capability of the TINT Service Center to the petroleum refinery was also enhanced

    One of the functions of government is to invest tax dollars in programs, projects, and properties that will result in greater public benefit than would have resulted from leaving the tax dollars in the private sector or using them to pay off the public debt. This paper describes the use of Net Present Value (NPV) as an approach to analyze and select investment opportunities for government money in public research, development, and demonstration (RD&D) programs and to evaluate potential private sector participation in the programs. This approach is then applied to a specific biomass-to-ethanol opportunity in California.

    In developing countries like Bangladesh, delayed presentation for disorders of sex development (DSD) is common, and provides some special problems for management. There remains significant controversy about appropriate sex assignment in this group. We aimed, therefore, to assess gender identity (GI) in 50 consecutive patients with DSD presenting to a referral centre in Chittagong, Bangladesh, and correlate it with Prader score, to see if the latter could be used to predict GI. A cross-sectional, case-control study of 50 consecutive children with DSD and 50 children with vascular anomalies was conducted in the Pediatric Surgical Clinic, Chittagong Medical College and Hospital. After informed consent, patients and controls provided oral answers to a GI questionnaire and had a detailed history and physical examination. Sex-typed activities were assessed by observations of a structured toy play and the child's selection of a toy to keep. Both patients and parents then completed the Child Game Participation Questionnaire. There were no differences in age (2-16 years, mean 8.74) between controls and DSD patients (11 46, XX DSD, 32 46, XY DSD, 4 MGD, 3 ovo-testicular DSD). Fifteen of the DSD patients (30 %) came from consanguineous marriages and only 2 of the control patients had consanguinity of their parents. For the 13-question GI interview, there was no overall difference between DSD cases and controls. For the 46, XX DSD subgroup, there was a significantly higher score (11.1 ± 7.1) compared with control girls (4.5 ± 4.7) (p gender-related behaviour correlated with Prader score for DSD patients (r = 0.61) (p gender-role behaviour should be assessed routinely in DSD patients presenting after the neonatal period, so that sex assignment is in accordance with behaviour. Prader scores showed a good correlation with GI and gender role behaviour.

    Full Text Available BACKGROUND Disorders of Sex Development (DSD, formerly described as intersex conditions, are a conglomerate of rare disorders defined as discrepancy of chromosomal, gonadal or anatomic sex. There are limited data on the incidence of DSD with an overall incidence of 1:5,500, but varies with population. Congenital adrenal hyperplasia and mixed gonadal dysgenesis are the most common causes of ambiguous genitalia constituting approximately 50% of all cases presenting with genital ambiguity at birth. The aim of the study is to study the clinical profile and aetiology, mean age of presentation of common aetiologies, initial sex of rearing based on genital ambiguity and correctness of sex of rearing since birth as compared to genetic karyotype after diagnosis of patients of various disorders of sex development presenting to endocrine OPD of a tertiary care hospital. MATERIALS AND METHODS We assessed the records of patients who were evaluated for hypogonadism and genital ambiguity between March 2014 to June 2017 in our endocrine department. The patients were classified on the basis of clinical features, hormonal investigations, imaging studies, karyotype and laparoscopy/biopsy studies as indicated. Design- Cross-sectional study. RESULTS Distribution of DSD by category were 46, XY DSD (41.6%; 46, XX DSD (27.3%; SCD DSD (30.9%. Distribution of DSD by subtypes were 46, XY DSD; -5α reductase (37.1%; IHH (20.1%; Kallmann syndrome (14.28%; bilateral anorchia (11%; PAIS (8.5%; CAIS (2.8%; CAH (2.8%; 46, XX DSD-CAH (34.1%; IHH (21.7%; 46, XX OTD (13%; ACC (8.6%; classic CAH (4.3%; SCD DSD-KFS (53.8%; TS (38.4% and MGD (7.69%.

    This article emphasises the importance of effective presentation skills. Such skills allow nurses to share knowledge and expertise and to communicate clearly in a range of workplace scenarios. Nurses are increasingly being asked to present in formal and informal situations, such as conferences, poster presentations, job interviews, case reports and ward-based teaching. This article explores the principles underpinning the development of these skills, discusses the situations in which they could be applied and demonstrates how nurses might improve and develop as presenters.

    Paris Climate Agreement is United Nations' Framework Convention on Climate Change way of encouraging countries to prepare Low-Emission development strategies and shows that climate change require long-term development strategies that support sustainable development, with the purpose of limiting the increase of global temperature to the maximal 2 degrees Celsius by the end of the century. The starting point of EU's policy towards low-emission economy is a goal of reducing greenhouse gas emissions by 80-95 percent by 2050. In accordance with that goal, The European Council adopted a climate-energy framework 2030 in October 2014, which sets a goal of reducing emissions - 40 percent by 2030. It also sets a goal of renewable energy sources share of up to 27 percent and an indicative goal of reducing energy consumption - 27 percent. At this moment, a process of accepting and consultations for regulatory climate-energy framework is taking part, as well as a change of greenhouse gas market directive, distribution of load on countries regulation and calculations of emissions from the sector of Land use, Land-use Change and Forestry (LULUCF) regulation. In 2015, The Ministry of Environment and Energy has started a project of making base documents for Low-Emission Development Strategy until 2030 with an outlook to 2050. This strategy applies to every economy and human activity sector and is especially linked to energy sector, industrial, transport, agriculture, forestry and waste management sectors. In the process of making base documents for the Strategy, a number of scenarios were analysed, models for simulations and optimisation were applied and an integral model for national greenhouse gas projections was developed. The Strategy outlines three scenarios: Reference scenario represents the application of the existing legislation while the other two scenarios present a transition towards low-emission economy: Gradual Transition Scenario (NU1) and Strong Transition Scenario

    We describe the delayed development of intracranial abscesses following emergent treatment with a covered stent-graft for carotid blowout syndrome (CBS) in a patient with head and neck cancer. The patient presented with hemoptysis and frank arterial bleeding through the tracheostomy site. A self-expandable stent-graft was deployed across a small pseudoaneurysm arising from the right common carotid artery (RCCA) and resulted in immediate hemostasis. Three months later, the patient suffered a recurrent hemorrhage. CT of the neck demonstrated periluminal fluid around the caudal aspect of the stent-graft with intraluminal thrombus and a small pseudoaneurysm. Subsequently, the patient underwent a balloon test occlusion study and endovascular sacrifice of the RCCA and right internal carotid artery. MRI of the brain demonstrated at least four ring-enhancing lesions within the right cerebral hemisphere consistent with intracranial abscesses that resolved with broad-spectrum antibiotic coverage.

    Full Text Available Abstract Background Synchronous presentation of more than one germ cell tumours of different histology in the same patient is considered to be very rare. In these cases of multiple germ cell tumours, strong theoretical and clinical data suggest an underlying common pathogenetic mechanism concerning genetic instability or abnormalities during the pluripotent embryonic differentiation and maturation of the germ cell. Case presentation A 25 year-old young man presented with an enlarging, slightly painful left cervical mass. Despite the initial disorientation of the diagnosis to a possible thyroid disorder, the patient underwent complete surgical resection of the mass revealing mediastinal choriocarcinoma. Subsequent ultrasound of the scrotum indicated the presence of a small lobular node in the upper pole of the left testicle and the patient underwent radical left inguinal orchiectomy disclosing a typical seminoma. Based on these results, the patient received 4 cycles of Bleomycin, Etoposide and Platinum chemotherapy experiencing only mild toxicity and resulting in complete ongoing clinical and biochemical remission. Conclusion The pathogenesis of concurrent germ cell tumours in the same patient remains an area of controversy. Although the genetic instability of the pluripotent germ cell offers an adequate explanation, the possibility of metastasis from the primary, less differentiated tumour to a distant location as a more mature subtype cannot be excluded. Possible development of a metastatic site of different histology and thus biological behaviour (e.g choriocarcinoma should be anticipated. Furthermore, urologists, pathologists and medical oncologists should be meticulous in the original pathological diagnosis in these patients, since there is a significant frequency of germ cell tumours with mixed or overlapping histological elements with diverse potential of evolution and differentiation.

    Full Text Available Bovine viral diarrhea virus (BVDV is an important cause of economic losses worldwide. E2 is an immunodominant protein and a promising candidate to develop subunit vaccines. To improve its immunogenicity, a truncated E2 (tE2 was fused to a single chain antibody named APCH, which targets to antigen-presenting cells. APCH-tE2 and tE2 proteins were expressed in the baculovirus system and their immunogenicity was firstly compared in guinea pigs. APCH-tE2 vaccine was the best one to evoke a humoral response, and for this reason, it was selected for a cattle vaccination experiment. All the bovines immunized with 1.5 µg of APCH-tE2 developed high levels of neutralizing antibodies against BVDV up to a year post-immunization, demonstrating its significant potential as a subunit vaccine. This novel vaccine is undergoing scale-up and was transferred to the private sector. Nowadays, it is being evaluated for registration as the first Argentinean subunit vaccine for cattle.

    Case-mix classification is a focus of international attention in considering how best to manage and fund services, by providing a basis for fairer comparison of resource utilization. Yet there is little evidence of the best ways to establish case mix for child and adolescent mental health services (CAMHS). To develop a case mix classification for CAMHS that is clinically meaningful and predictive of number of appointments attended and to investigate the influence of presenting problems, context and complexity factors and provider variation. We analysed 4573 completed episodes of outpatient care from 11 English CAMHS. Cluster analysis, regression trees and a conceptual classification based on clinical best practice guidelines were compared regarding their ability to predict number of appointments, using mixed effects negative binomial regression. The conceptual classification is clinically meaningful and did as well as data-driven classifications in accounting for number of appointments. There was little evidence for effects of complexity or context factors, with the possible exception of school attendance problems. Substantial variation in resource provision between providers was not explained well by case mix. The conceptually-derived classification merits further testing and development in the context of collaborative decision making.

    Elgzeli, Y.M., Ondovčin, T., Hrkal, Z., Krasny, J. and Mls, J. 2011. Impacts of heavy groundwater pumping on hydrogeological conditions in Libya: Past and present development and future prognosis on a regional scale. Acta Geologica Polonica, 63 (2), 283-296. Warszawa. Libya, like many other regions with arid climates, suffers from inadequate water resources to cover all the needs of this rapidly developing country. Increasing amounts of water are needed to supply the population, as well as for agricultural irrigation and industrial use. As groundwater is the main water source in the country, it represents a natural resource of the highest economic and social importance. Conceptual and numerical models were implemented on a regional scale to show how the natural situation has changed following heavy groundwater abstraction during the last decades in the northwestern part of the country. The results of the numerical model indicated that the current zones of depression of the piezometric surface could have been caused by smaller withdrawn amounts than previously estimated. The differences in the assessed withdrawn groundwater volumes seem to be quite high and might have a considerable influence on the future possibilities of groundwater use in the study region.

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

  5. The present, past and future of the study of intellectual disability: challenges in developing countries Pasado, presente y futuro del estudio de la discapacidad intelectual: desafíos en los países en desarrollo

    Trevor R Parmenter

    2008-01-01

    Full Text Available There is strong evidence that socio-cultural factors largely determine what is seen as competent behaviour. Within western high income countries, driven by the values of utilitarian individualism, the construct of intellectual disability has been largely determined to meet the needs of urban, industrialised societies. In contrast, competence in non-industrialised societies may be more reflected in collaborative, interpersonal problem solving skills such as those found among Nigerian students labelled as intellectually disabled. However, people who are judged to be incompetent or "obtrusive" in countries deficient in support services, are often neglected and consigned to a life in poorly managed segregated institutions, as is the case in China, Russia and some countries in Eastern Europe. Non western countries that have a long history of a globalised economy, such as Taiwan and Japan also remain committed to segregated institutional provisions for people with an intellectual disability, despite a notional acceptance of inclusionary policies enunciated by the United Nations’ Declarations and Conventions. In this paper is concluded that it must be recognised that the population of people with an intellectual disability, regardless of how the condition is defined and classified, is quite heterogeneous. Their needs are also varied and not at all dissimilar to those of the general population. As developing countries adopt western style consumer-driven economies, there is an extreme danger that they, too, will follow the same trajectory of exclusion and impose the culture of "otherness" for a group whose contribution to that society will be devalued. Good science is futile unless it benefits all peoples.Existe amplia evidencia de que los factores socioculturales determinan en gran medida la percepción de conducta competitiva.

    Studies performed with canines indicate that one of the main neoplasia which affect these animals are the breast tumors, representing from 25% to 50% of all kinds of tumors. Moreover, half of them are classified as malignant. In this sense, recent researches on humans have been associated the presence of certain trace elements with the development of breast neoplasia in those individuals. Then, as the breast tissue composition in canines is very similar to the humans, it is expected the same behavior. In this direction, a very effective technique to identify and to determinate trace elements concentration is the EDXRF. However, studies on this area are scarce in the literature. Therefore, in this work it was developed an approach to quantify the main trace elements present into these tumors with high sensitivity. For this purpose, it was determined calibration curves of standards samples diluted in water, with concentrations of Ca, Fe, Cu and Zn, ranging from 400mg/kg to 35mg/kg, from 20mg/kg to 2mg/kg, from 10mg/kg to 1mg/kg and from 100mg/kg to 10mg/kg, respectively. All calibration curves were linearly fitted and on basis in this behavior it was determined the sensitivity of our approach to quantify the concentration of the trace elements mentioned above. In addition, it is important to mention that studies in this area are of great potential, because EDXRF represents a quickly practical and non-destructive alternative to quantify trace elements.

    Full Text Available As many nuclear power plants are reaching their end of lifecycle, the decommissioning of these installations has become one of the 21st century’s great challenges. Each project may be managed differently, depending on the country, development policies, financial considerations, and the availability of qualified engineers or specialized companies to handle such projects. The principle objective of decommissioning is to place a facility into such a condition that there is no unacceptable risk from the decommissioned facility to public health and safety of the environment. In order to ensure that at the end of its life the risk from a facility is within acceptable bounds, action is normally required. The overall decommissioning strategy is to deliver a timely, costeffective program while maintaining high standards of safety, security and environmental protection. If facilities were not decommissioned, they could degrade and potentially present an environmental radiological hazard in the future. Simply abandoning or leaving a facility after ceasing operations is not considered to be an acceptable alternative to decommissioning.The final aim of decommissioning is to recover the geographic site to its original condition.

    A simple, sensitive and reproducible ultra performance liquid chromatography (UPLC) coupled with a photodiode array detector method was developed for the quantitative determination of olanzapine (OLN) in API and pharmaceutical dosage forms. The method is applicable to the quantification of related substances and assays of drug substances. Chromatographic separation was achieved on Acquity UPLC BEH 100-mm, 2.1-mm, and 1.7-μm C-18 columns, and the gradient eluted within a short runtime, i.e., within 10.0 min. The eluted compounds were monitored at 250 nm, the flow rate was 0.3 mL/min, and the column oven temperature was maintained at 27°C. The resolution of OLN and eight (potential, bi-products and degradation) impurities was greater than 2.0 for all pairs of components. The high correlation coefficient (r(2)>0.9991) values indicated clear correlations between the investigated compound concentrations and their peak areas within the test ranges. The repeatability and intermediate precision, expressed by the RSD, were less than 2.4%. The accuracy and validity of the method were further ascertained by performing recovery studies via a spike method. The accuracy of the method expressed as relative error was satisfactory. No interference was observed from concomitant substances normally added to the tablets. The drug was subjected to the International Conference on Harmonization (ICH)-prescribed hydrolytic, oxidative, photolytic and thermal stress conditions. The performance of the method was validated according to the present ICH guidelines for specificity, limit of detection, limit of quantification, linearity, accuracy, precision, ruggedness and robustness.

    In the last few years Multiphoton Excitation Microscopy witnessed a mutation from tool for imaging cellular structures in living animals deeper than other high-resolution techniques, into an instrument for monitoring functionality and even stimulating or inhibiting inter-cellular signalling. This paradigm shift has been enabled primarily by the development of genetically encoded probes like Ca indicators (GECI) and Opsins for optogenetics inhibition and stimulation. These developments will hopefully enable the understanding of how local network of hundreds or thousands of neurons operate in response to actual tasks or induced stimuli. Imaging, monitoring signals and activating neurons, all on a millisecond time scale, requires new laser tools providing a combination of wavelengths, higher powers and operating regimes different from the ones traditionally used for classic multiphoton imaging. The other key development in multiphoton techniques relates to potential diagnostic and clinical applications where non-linear imaging could provide all optical marker-free replacement of H and E techniques and even intra-operative guidance for procedures like cancer surgery. These developments will eventually drive the development of specialized laser sources where compact size, ease of use, beam delivery and cost are primary concerns. In this talk we will discuss recent laser product developments targeting the various applications of multiphoton imaging, as fiber lasers and other new type of lasers gradually gain popularity and their own space, side-by-side or as an alternative to conventional titanium sapphire femtosecond lasers.

    Full Text Available The aim of this study was to investigate the effectiveness of using students’ presentations on improving English language skills of adult learners and assess its potency to reach the expected learning outcomes. The research was conducted in the Continuing Education Center, Ishik University, Erbil, KRG, Iraq. The target population consisted of 23 English language learners (university graduates, and currently working in the sphere of Education. This study consisted of three major phases: first, explanation, preparation, presentation of the students’ works on the topic of interest and observation of students’ performance, second, teacher-student and student-student discussion of the video-recorded presentations. The last step was the application of the survey, which was designed to measure the participants’ attitude toward the mini-projects they presented in the class. The data were analyzed by means of frequency and percentage, as well as a summarization of the discussions. The main findings show that students’ attitude toward oral presentations, prepared on the topic of their own interest, have a positive attitude on students’ motivation toward learning English and help the adult learners to improve their language in general, and the productive skills in particular.

    International Nuclear Information System (INIS)

    2010-01-01

    In her introduction, the author gives a description of the difficult context and situation faced by the industrial sector in France, notably because of the growing activity of emerging countries like China, India or Brazil, but also because of the weakness of research industrial valorization and of the innovation policy (losing the manufacturing capacity leads to losing the capacity for innovation). Then, after a critic of the current policy (reform of the professional tax, a boosting plan with limited results), she comments the contents of public programmes concerning firm and job development, energy, the steering of ecology, energy, sustainable development and sea policies, research in energy and sustainable development and land planning. She comments ways and tools aimed at supporting industrial jobs through innovation: the FSI (strategic investment fund), the competitiveness poles, specific aids to small and medium sized enterprises, tax credit related to research activities. She addresses the energy sector, questioning the French supremacy in the nuclear energy and the increase of electricity price, and criticizing the management of the development of renewable energies (high expenses for no industrial development)

    Full Text Available Helminth parasites are an assemblage of two major phyla of nematodes (also known as roundworms and platyhelminths (also called flatworms. These parasites are a major human health burden, and infections caused by helminths are considered under neglected tropical diseases (NTDs. These infections are typified by limited clinical treatment options and threat of drug resistance. Aminoacyl-tRNA synthetases (aaRSs are vital enzymes that decode genetic information and enable protein translation. The specific inhibition of pathogen aaRSs bores well for development of next generation anti-parasitics. Here, we have identified and annotated aaRSs and accessory proteins from Loa loa (nematode and Schistosoma mansoni (flatworm to provide a glimpse of these protein translation enzymes within these parasites. Using purified parasitic lysyl-tRNA synthetases (KRSs, we developed series of assays that address KRS enzymatic activity, oligomeric states, crystal structure and inhibition profiles. We show that L. loa and S. mansoni KRSs are potently inhibited by the fungal metabolite cladosporin. Our co-crystal structure of Loa loa KRS-cladosporin complex reveals key interacting residues and provides a platform for structure-based drug development. This work hence provides a new direction for both novel target discovery and inhibitor development against eukaryotic pathogens that include L. loa and S. mansoni.

    Emmerson, B.W.

    1989-01-01

    Since the mid-1950's nuclear energy has played an increasing role in meeting the world demand for electricity production. Although during this period incidents and accidents have occurred, in most cases their effect was confined to the plant. Three accidents, however, were sufficienty serious as to involve off-site consequences for the public. The experience from each contributed significantly in the development of current emergency response criteria and planning arrangements at the national and international level. This paper summarizes these contributions as they relate to the development of intervention levels for the protection of the public in the event of an accidental release of radioactive materials to the environment. It indicates the various measures taken by those countries that were affected by the release from the Chernobyl accident and reviews the subsequent actions by relevant international organizations to provide more comprehensive guidance on applying the principles of intervention and developing derived levels, particularly those aimed at controlling the consumption of contamined foodstuffs, or their movement in international trade. Finally, it considers the prospects for developing a more harmonized intervention approach based on the guidance now being completed at the international level [fr

    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

    The recent Philippine National Health Research System (PNHRS) Week Celebration highlighted the growing commitment to Disaster Risk Reduction (DRR) in the Philippines. The event was lead by the Philippine Council for Health Research and Development of the Department of Science and Technology and the Department of Health, and saw the participation of national and international experts in DRR, and numerous research consortia from all over the Philippines. With a central focus on the Sendai Framework for Disaster Risk Reduction, the DRR related events recognised the significant disaster risks faced in the Philippines. They also illustrated the Philippine strengths and experience in DRR. Key innovations in science and technology showcased at the conference include the web-base hazard mapping applications 'Project NOAH' and 'FaultFinder'. Other notable innovations include 'Surveillance in Post Extreme Emergencies and Disasters' (SPEED) which monitors potential outbreaks through a syndromic reporting system. Three areas noted for further development in DRR science and technology included: integrated national hazard assessment, strengthened collaboration, and improved documentation. Finally, the event saw the proposal to develop the Philippines into a global hub for DRR. The combination of the risk profile of the Philippines, established national structures and experience in DRR, as well as scientific and technological innovation in this field are potential factors that could position the Philippines as a future global leader in DRR. The purpose of this article is to formally document the key messages of the DRR-related events of the PNHRS Week Celebration.

    What is the incidence of contractures six months after stroke? Can factors measured within four weeks of stroke predict the development of elbow, wrist, and ankle contractures six months later? Prospective cohort study. Consecutive sample of 200 adults with stroke admitted to a Sydney hospital. Loss of range of motion in major joints of the body was measured using a 4-point ordinal contracture scale. In addition, elbow extension, wrist extension, and ankle dorsiflexion range of motion were measured using torque-controlled procedures. Potential predictors of contracture were age, pre-morbid function, severity of stroke, muscle strength, spasticity, motor function, and pain. Measurements were obtained within four weeks of stroke and at six months after stroke. 52% of participants developed at least one contracture. Incidence of contracture varied across joints from 12% to 28%; shoulders and hips were most commonly affected. Muscle strength was a significant predictor of elbow, wrist, and ankle joint range. Prediction models explained only 6% to 20% of variance in elbow, wrist, and ankle joint range. About half of all patients with stroke develop at least one contracture within six months of stroke. Incidence of contractures across all joints ranged from 12% to 28%. Muscle strength is a significant predictor of elbow, wrist, and ankle contractures but cannot be used to accurately predict contractures in these joints.

    The information revolution is transforming health technology itself. With the development of international fiberoptic networks, satellite communications and the ever expanding Internet, technology is now going from revolutionary to routine, from unimaginable to indispensable. There has been little practical experience with telemedicine of a direct clinical kind in the developing world which contains 80% of the world's population. In the 45 poorest countries, it is estimated that only 50% of the population have access to health services. Arguably, it is those same countries that stand to gain most from a simple and cheap telemedicine system, on the principle that it could improve access to health care specialists and enhance research and the education of local health care workers. The work of the Swinfen Charitable trust demonstrates, useful clinical and educational results can be achieved using low cost telemedicine methods. As with the rest of telemedicine, the guiding principle seems to be that it is important to be clear about what problem we are trying to solve. Bangladesh has already entered the age of telemedicine. Under the umbrella of the IAEA TC Project on tele-nuclear medicine and tele-maintenance of nuclear medical equipment it will gradually step forward to reach its desired goal. What role telemedicine will play in the developing countries is yet to be determined. In terms of global health care the relevancy of telemedicine can only be ascertained after successful implementation of these projects

    We aimed to assess how the diagnosis and determination of gender identity of disorders of sex development (DSD) is different in a developing country from Western medicine, and whether a pediatric surgery department can determine the underlying diagnosis and use simple tools to determine the likely gender identity (GI). We reviewed the records of DSD patients admitted to the Department of Pediatric Surgery, Chittagong Medical College & Hospital (CMCH), Chittagong, Bangladesh, from January 2006 to December 2012 and performed a cross-sectional study on GI and gender-related behavior in these patients during the year 2012. DSD boys and girls answered a GI interview and had their gender role behavior assessed by observations of structural toy play and analyzed for differences in scores. This cohort of DSD patients presented in mid-childhood (6 months-16 years, mean 6.9 years) rather than infancy, and 30% came from consanguineous unions. Congenital adrenal hyperplasia (CAH) constituted only 11 of 50 (22%) of the DSD cohort, and not all families had access to steroid hormone replacement. A simple assessment of GI and gender-related behavior allowed effective gender assignment, as there was significant difference between DSD boys and girls in GI and gender-related behavior score. DSD management in Bangladesh provides some unique challenges because of limited resources. A national reference laboratory for biochemical and genetic testing and development of a quaternary referral center for DSD patients will be helpful. Continued use of the GI interview and gender-related behavior study will enable effective interim decisions about diagnosis and management. Copyright © 2014 Journal of Pediatric Urology Company.

    Full Text Available The aim of this study was to search Salmonella spp. occurrence in broiler poultry shed and poultry products from slaughterhouse in central county of Mato Grosso do Sul. Were analyzed 134 drag swabs in broiler poultry farms located in five counties 123 samples of chickens carcasses, viscera and chilled water from the slaughterhouse. The results showed that 11.28% of 257 samples tested positive for Salmonella, and 1.95% from the field and 9.33% from the slaughterhouse. The serovars found were Salmonella Enteritidis (1.16%, S. Typhimurium (1.94%, S. Senftenberg (0.77%, S. Schwarzengrund (4.28%, S. Livingstone (0.38%, S. Corvallis (1.55% and Salmonella enterica subspecies enterica (O: 4.5:-:1.2 with 1.16%. The use of two enrichment broths and two or more plating means increases the chances of Salmonella spp. Isolation. The serovars Enteritidis and Typhimurium, important in the poultry industry, were found in field and slaughterhouse. It can be concluded that there is an occurrence of different serovars of Salmonella spp. In poultry slaughterhouse and in Mato Grosso do Sul central county. Serovar Schwarzengrum shows the highest percentage of occurrence in the slaughterhouse, suggesting that further studies are conducted to determine the importance of presence compared to other serovars. Control programs and risk analysis are essential for maintaining the health of poultry and reduce potential health risks to the consumer.Objetivou-se com este estudo pesquisar a ocorrência de Salmonella spp. em aviários de frangos de corte e em produtos de abatedouro avícola na região central de Mato Grosso do Sul.

    Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU-Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU and Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

    Full Text Available The determination of the specific environment is important for the formulation of efficient enterprise strategies, on the basis of a strategic analysis properly focused. This paper suggests a method to help its limitation and identification. With its use, it pretends to offer a simple and practical tool that allows to have a more accurate approach to the identification of the industry that will be analysed, as well as, a clarification of the specification of the direct and substitute competition. Also, with the use of this tool, the managers of a business idea, an experienced or new organization, will have an approximation to the mentioned themes that are of a strategic importance in any management type. Likewise, two applications of the proposed method are presented: the first orientated to a business idea and the second to supermarkets with a high service charge in Lima, Peru.

    In this paper, the background of performance testing of in-service process flow compressors set in user field are introduced, the main technique barriers faced in the field test are summarized, and the factors that result in real efficiencies of most process flow compressors being lower than the guaranteed by manufacturer are analysed. The authors investigated the present operational situation of process flow compressors in China and found that low efficiency operation of flow compressors is because the compressed gas is generally forced to flow back into the inlet pipe for adapting to the process parameters variety. For example, the anti-surge valve is always opened for centrifugal compressor. To improve the operation efficiency of process compressors the energy efficiency monitoring technology was overviewed and some suggestions are proposed in the paper, which is the basis of research on energy efficiency evaluation and/or labelling of process compressors.

  18. Present status of the wholesomeness of irradiated foods of basic interest to developing countries, in particular to those in the Asian and Pacific regions

    Among the irradiated foods, the safety of which has already been unconditionally accepted by the Joint Expert Committee on Food Irradiation, are some that, as major items of food, are of considerable interest to the developing countries. There exist, however, technical and economic constraints. The process apparently offers greater promise for certain high-value foods, e.g. frozen sea-foods, spices and tropical fruits for which conventional processing methods fail to yield products that meet hygienic standards, especially of importing nations. The acceptance of such foods from developing countries by the industrialized importing countries could give a boost to food irradiation activities. Most food irradiation applications in practice are likely to be combination processes involving the use of other chemical or physical agents, and the regulatory approach requires rationalization. Wholesomeness of the product subjected to a combination process cannot be inferred merely on the basis of each component of the combination treatment being individually recognized as yielding a wholesome product. Studies on the radiation chemistry of various classes of foods and model systems have served to emphasize their predictive value and have led to the concept of 'chemiclearance' for extrapolating wholesomeness from one food to another in the same general category. It should, however, be emphasized that excessive or undue reliance on the chemical data, coupled with the rigid attitude of some health authorities in respect of the presence of genetic toxicants (zero tolerance), could result in the absurb situation of the chemical approach invalidating the far more relevant animal experimental data on safety

    Among the irradiated foods, the safety of which has already been unconditionally accepted by the Joint Expert Committee on Food Irradiation, are some that, as major items of food, are of considerable interest to the developing countries. However, the anticipated practical adoption of the technology has not taken place owing to the existence of technical and economic constraints. It would appear that the process offers greater promise for certain high-value items of food, e.g. frozen sea-foods, spices and tropical fruits for which conventional processing methods are inadequate to yield products that meet hygienic standards, especially of importing nations. The acceptance of such foods originating from developing countries by the industrialized importing countries could give a boost to food irradiation activities in the former. Most food irradiation applications in practice are likely to be combination processes involving the use of other chemical or physical agents, and the regulatory philosophy with respect to such treatments requires rationalization. It would be a stupendous task to establish experimentally the safety of the same food product subjected to different combination treatments; wholesomeness of the product subjected to a combination process cannot be inferred merely on the basis of each component of the combination treatment being individually recognized as yielding a wholesome product. Studies on the radiation chemistry of various classes of foods and model systems have served to emphasize their predictive value and have led to the concept of 'chemiclearance' for extrapolating wholesomeness from one food to another in the same general category.

    CUB domain containing protein 1 (CDCP1) is a transmembrane protein involved in progression of several cancers. When located on the plasma membrane, full-length 135kDa CDCP1 can undergo proteolysis mediated by serine proteases that cleave after two adjacent amino acids (arginine 368 and lysine 369). This releases from the cell surface two 65kDa fragments, collectively termed ShE-CDCP1, that differ by one carboxyl terminal residue. To evaluate the function of CDCP1 and its potential utility as a cancer biomarker, in this study we developed an enzyme-linked immunosorbent assay (ELISA) to reliably and easily measure the concentration of ShE-CDCP1 in biological samples. Using a reference standard we demonstrate that the developed ELISA has a working range of 0.68-26.5ng/ml, and the limit of detection is 0.25ng/ml. It displays high intra-assay (repeatability) and high inter-assay (reproducibility) precision with all coefficients of variation ≤7%. The ELISA also displays high accuracy detecting ShE-CDCP1 levels at ≥94.8% of actual concentration using quality control samples. We employed the ELISA to measure the concentration of ShE-CDCP1 in human serum samples with our results suggesting that levels are significantly higher in serum of colorectal cancer patients compared with serum from individuals with benign conditions (pELISA is a suitable method to quantify ShE-CDCP1 concentration in human serum.
