    Full Text Available There are no currently approved treatments for filovirus infections. 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.

    This paper describes the requirements, design and initial performance of the Advanced Inventory Verification Sample System (AVIS) a non-destructive assay (NDA) system to measure small samples of bulk mixed uranium-plutonium oxide (MOX) materials (powders and pellets). The AVIS design has evolved from previously developed conceptual physics and engineering designs for the Inventory Sample Verification System (INVS), a safeguards system for nondestructive assay of small samples. The AVIS is an integrated gamma-neutron system. Jointly designed by the Nuclear Material Control Center (NMCC) and the Los Alamos National Laboratory (LANL), AVIS is intended to meet a performance specification of a total measurement uncertainty of less than 0.5% in the neutron ({sup 240}Pu{sub effective}) measurement. This will allow the AVIS to replace destructive chemical analysis for many samples, with concomitant cost, exposure and waste generation savings for the facility. Data taken to date confirming the performance of the AVIS is presented.

    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)

    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)

    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.

    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)

    Few guidelines exist regarding the most effective approach to scientific oral presentations. Our purpose is to (1) develop a standardized instrument to evaluate scientific presentations based on a comprehensive review of the available literature regarding the components and organization of scientific presentations and (2) describe the optimal characteristics of scientific presentations. At the Sixty-sixth (2011) Annual Meeting of the American Society for Surgery of the Hand, 69 presentations were evaluated by at least 2 independent observers. A rating instrument was developed a priori to examine presentation content (background, methods, results, and conclusions), presentation style (speech, structure, delivery, slide aesthetics), and overall quality. We examined correlations between reviewers' ratings of each component as well as overall perceived quality of the presentation using regression analysis. Intraclass correlation coefficients were calculated to measure the degree of variation because of reviewer disagreement and identify the aspects of presentations that contribute to overall quality. Reviewer agreement was high for presentation content, and less than 1% of variation was caused by reviewer disagreement for background, methods, and conclusions. With respect to presentation style, reviewers agreed most frequently regarding speech and slide appearance, and only 9% and 13%, respectively, of the variation was caused by reviewer disagreement. Disagreement was higher for delivery and presentation structure, and 21% of the variation was attributable to reviewer disagreement. Speaker delivery and slide appearance were the most important predictors of presentation quality, followed by the quality of the presentation of conclusions and background information. Presentation of methods and results were not associated with overall presentation quality. Distinct aspects of presentation content and style correlate with quality, which can be reliably and objectively

    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.

    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

  8. Habenula circuit development: past, present and future

    Directory of Open Access Journals (Sweden)

    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

    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.

    Full Text Available No presente trabalho é relatado caso de intoxicação crônica por cobre (ICC ocorridos em rebanho ovino pastoreados em pomar de videiras, na serra Gaúcha; suplementados com bagaço de uva e concentrado. O pomar era aspergido anualmente com solução de sulfato de cobre a 2% e teve seu solo adubado com cama aviária. Os ovinos mostraram andar cambaleante, icterícia intensa das mucosas e urina escura, dos quais foram a óbito oito animais, correspondendo a 57% do total do rebanho. Os sinais clínicos e lesões histológicas foram características da ICC. A dosagem de Aspartato Aminotrasferase (AST no soro dos seis ovinos remanescentes variou de 48,8 a 403,3 UI/L. O nível de cobre encontrado na cama aviária, bagaço de uva, pastagem e concentrado foram de 637, 158, 86 e 18 mg/kg respectivamente. Conclui-se que os óbitos ocorreram devido ao alto nível de cobre encontrado na pastagem, bagaço de uva e concentrado administrado aos animais. Sugere-se também, o risco de dano ambiental no uso de cama aviária na adubação de pastagem, assim como a inadequação da alimentação de ovinos com bagaço de uva.

    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.)

    Expert communication skills are essential for nurse leaders to effectively influence health care. Because effective communication is a learned process, the curriculum should promote the development of presentation skills. An educational strategy was designed to promote the development of effective presentation skills for learners in the Nursing Leadership and Administration (NLA) track of the master's in nursing curriculum. Sixteen learners in the NLA cohort were participants in a three-session presentation skills workshop. Following a baseline presentation, participants were taught presentation strategies and skills. Expert evaluators and learner self-assessments rated their presentation skills. Analysis of evaluators' ratings showed statistically significant (p presentation effectiveness. Analysis of learner self-ratings showed a statistically significant (p = .008) increase in perceived effectiveness of overall presentation skills. This unique educational intervention improved nurse leaders' presentation skills. Faculty found that the professional presentation skill workshop was important to learners' success.

    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.

    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

    Directory of Open Access Journals (Sweden)

    José da Silva Guimarães Junior

    2012-06-01

    Full Text Available The genus Eimeria belonging to the Subphylum Apicomplexa, Family Eimeriidae, have seven recognized species infecting chickens: E.acervulina, E. maxima, E.tenella, E.brunetti, E.necatrix, E.mitis and E.praecox. It’s an obligate intracellular parasite that causes disease by the destruction of intestinal epithelial cells in the replication process. The indiscriminate use of anticoccidial drugs has resulted in the selection of drug-resistant strains, which reduce de effectiveness of various anticoccidial drugs used currently in control of the disease. As in many countries legislation prohibits the use of thes products continuously until slaughter withdrawal periods have been required, which increases the risk of infection at the end of the growing season. Thus, vaccines are essential as a tool for controlling these parasites. There are several types of vaccines, but only attenuated live vaccines are marketed for the control of avian coccidiosis, with the exception of recombinant vaccine CoxAbic®. Nevertheless, its use is still mild compared to the use of anticoccidial drugs, possibly due to its lower cost and greater effectiveness. Thus, it is important that control of avian coccidiosis is extremely complex, and that further studies should be encouraged to develop effective methods, including the use of vaccines for the production of chicken meat free of medication. O gênero Eimeria pertencente ao subfilo Apicomplexa, Família Eimeriidae com sete espécies reconhecidas infectando galinhas: E.acervulina, E.maxima, E.tenella, E.brunetti, E.necatrix, E.mitis e E.praecox. Trata-se de um parasito intracelular obrigatório que causa doença pela destruição de células do epitélio intestinal em seu processo de replicação. O uso indiscriminado de anticoccídicos tem resultado na seleção de cepas resistentes a drogas, as quais reduzem a eficácia de vários anticoccídicos usados atualmente no controle dessa parasitose.

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...

    2011-01-01

    A new self-report measure of adolescent's self-presentation is described. The self-report scale was administered to 760 16-19-year-old subjects. Results of a factor analysis supported 6 identifiable factors reflecting different concepts, theoretically discussed, related to self-presentation: ability to regulate self-image, social sensitivity, body self-confidence, social self-confidence, social openness, and social desirability. The scale showed good convergent validity and internal consistency. Assertive tactics were predicted through ability to regulate self-image, social self-confidence, and social openness, whereas defensive tactics were predicted only through social openness and social sensitivity. The implications of the findings for future theoretical and empirical development of research in this field are discussed.

    The book of the same title as this one was published in 1983. Since then, the situation requiring the correction of the contents, such as the correction of uranium resource policy in various countries accompanying the change of uranium market condition and the change of uranium policy in Australia due to the political situation, has occurred, consequently, the revision has been made adding these new information. The confirmed resources of uranium and the resources of uranium to be added by estimation in the free world are tabulated. About each country, the organization and policy, the policy of exporting uranium and the present status of the export, the quantity of uranium resources, the production of uranium, the state of exploration and development and so on are reported. Japan has taken part in the development of uranium resources in Australia, Canada, Gabon, Zambia, Morocco, Guinea, Mali and so on. (Kako, I.)

    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.

    Infection of Mycobacterium tuberculosis (MTB) was observed as early as 5000 years ago with evidence, which is a primeval enemy of the humanoid race. MTB is the pathogen which is responsible for causing the infectious disease tuberculosis; it remains a major cause of morbidity and mortality in poor low-income countries as well as in developing countries because of non-availability of reliable laboratory facilities. The current treatment for drug-resistant tuberculosis (TB) is lengthy, complex, and connected with severe harmful side effects and poor outcomes. The present cure against tuberculosis has substantial restrictions, in terms of their efficiency, side-effect outline, and complication of handling. Furthermore, the emergence of multi-drug resistant tuberculosis (MDR-TB) outbreaks during the 1990s and additionally in recent times the vast deadly strains of extensively drug-resistant tuberculosis (XDR-TB) and totally drug resistance tuberculosis (TDR-TB) is hampering efforts to control and manage tuberculosis (TB). As a result, novel methodologies for the treatment of multi-drug-resistant and extensive drug-resistant tuberculosis (TB) are severely desired. A number of new potential anti-tuberculosis drug candidates with novel modes of action have been entered in clinical trials in recent years. These agents are most likely to be effective against resistant strains. The treatment landscape is beginning to shift, with the recent approvals by Food and Drug Administration to the new TB drugs bedaquiline and delamanid. Also, the pipeline of potential new treatments has been fulfilled with several compounds in clinical trials or preclinical development with promising activities against sensitive and resistant MTB bacteria. An additional new chemical entity is also under development. The already existing drugs with their suggested mode of treatment as well as new probable anti-tuberculosis drug moieties which are at present in the pipeline has been summarized in this

    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.

    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.)

    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)

  18. Present Status and Future Developments in Proton Therapy

    International Nuclear Information System (INIS)

    Smith, Alfred R.

    2009-01-01

    Within the past few years, interest in proton therapy has significantly increased. This interest has been generated by a number of factors including: 1) the reporting of positive clinical results using proton beams; 2) approval of reimbursement for delivery of proton therapy; 3) the success of hospital-based proton therapy centers; and 4) the availability of modern, integrated proton therapy technology for hospital-based facilities. In the United States, this increased interest has occurred particularly at the level of smaller academic hospitals, community medical centers, and large private practices; however, interest from large academic centers continues to be strong. Particular interest exists regarding smaller and less-expensive proton therapy systems, especially the so-called 'single-room' systems. In this paper, the advantages and disadvantages of 1-room proton therapy systems will be discussed. The emphasis on smaller and cheaper proton therapy facilities has also generated interest in new proton-accelerating technologies such as superconducting cyclotrons and synchrocyclotrons, laser acceleration, and dielectric-wall accelerators. Superconducting magnets are also being developed to decrease the size and weight of isocentric gantries. Another important technical development is spot-beam scanning, which offers the ability to deliver intensity-modulated proton treatments (IMPT). IMPT has the potential to provide dose distributions that are superior to those for photon intensity modulation techniques (IMXT) and to improve clinical outcomes for patients undergoing cancer therapy. At the present time, only two facilities--one in Europe and one in the United States--have the ability to deliver IMPT treatments, however, within the next year or two several additional facilities are expected to achieve this capability.

The Technical Design Report (TDR) will include a description of the updated design, with a cost estimate and a project plan, and the results of research and development (R & D) done in support of the ILC. Results from directed ILC R & D are used to reduce the cost and risk associated with the ILC design. We present a summary of key challenges and show how the global R & D effort has addressed them. The most important activity has been in pursuit of very high gradient superconducting RF linac technology. There has been excellent progress toward the goal of practical industrial production of niobium sheet-metal cavities with gradient performance in excess of 35 MV/m. In addition, three purpose-built beam test facilities have been constructed and used to study and demonstrate high current linac performance, electron-cloud beam dynamics and precision beam control. The report also includes a summary of component design studies and conventional facilities cost optimization design studies.

    Retained austenite and other microstructural components in a series of Cu-Mo-Ni-alloyed austempered ductile iron, ADI, and V-Cu-bearing austempered vermicular iron, AVI, have been determined by means of Rietveld analysis, as a promising alternative to the usual technique based on the integrated intensities of X-ray diffraction patterns. The Rietveld method utilizes all measured points of the diffraction pattern and minimizes the residual S = w{sub i} (y{sub i}-y{sub c}){sup 2} with w{sub i} = 1/y{sub i}, y{sub i} = observed intensity and y{sub c}=calculated intensity. For the sake of this research the analytical reflection profiles were modeled according to the Pearson VII and pseudo-Voigt functions. The described refinement procedure yielded highly precise results, as compared with the traditional techniques; besides, very useful corrections for preferred orientations, background and micro displacement of the specimen can be mathematically modeled.

    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.

    The technology and resource-rich solutions of the developed world may not be completely applicable to or replicable in disasters occurring in the developing world. With the current looming hazards of pandemics, climate change, global terrorism and conflicts around the world, policy makers and governments will need high-quality scientific data to make informed decisions for preparedness and mitigation. The evidence on disasters in peer-reviewed journals about the developing world was examined for quality and quantity in this systematic review. PubMed was searched using the Medical Subject Heading (MeSH) terms disasters, disaster medicine, rescue work, relief work, and conflict and then refined using the MeSH term developing country. The final list of selected manuscripts were analyzed by type of article, level of evidence, theme of the manuscript and topic, author affiliation, and region of the study. After searching and refining, developing countries. The majority was original research articles or reviews, and most of the original research articles were level IV or V evidence. Less than 25% of the authors were from the developing world. The predominant themes were missions, health care provision, and humanitarian aid during the acute phase of disasters in the developing world. Considering that 85% of disasters and 95% of disaster-related deaths occur in the developing world, the overwhelming number of casualties has contributed insignificantly to the world's peer-reviewed literature. Less than 1% of all disaster-related publications are about disasters in the developing world. This may be a publication bias, or it may be a genuine lack of submissions dealing with these disasters. Authors in this part of the world need to contribute to future disaster research through better-quality systematic research and better funding priorities. Aid for sustaining long-term disaster research may be a more useful investment in mitigating future disasters than short

  8. Present status and problems of development of fast breeder reactors

    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.

    1980-01-01

    The model protective tetanic vaccination in mice was used in order to try whether the paramunity inducer Pind-Avi may diminish or suspend radiation-induced immunosuppression. The radioprotective effect was ascertained from the different results of immunization in mice exposed to radiation after pretreatment with either Pind-Avi or placebo. The dose delivered amounted to 300 R. Tetanus toxoid was used for immunization. Effectiveness of the tetanic vaccination was analysed by means of load tests with 10 LD 50 tetanus toxin, and of antibody determination with passive hemagglutination. Evidence was shown of significant radiation protection following subcutaneous application of Pind-Avi once a day during three days before of after exposure. Efficiency in mice treated with Pind-Avi amounted to 75% (pre-irradiation treatment) and to 43% (postirradiation treatment), whereas the efficiency in controls was zero in all cases. Thus, it was possible with Pind-Avi to suspend radiation-induced immunosuppression within a period of 3 days before or after radiation exposure, not only by means of prophylactic but also by therapeutic administration.

    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)

    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.

    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.

    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.)

    Science.gov (United States)

    1993-03-01

    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.

    1998-01-01

    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)

    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.)

    Miyamoto, Yoshiaki

    2000-01-01

    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.

    1965-04-01

    Full Text Available A hangar for the Shah's private aircraft has been built in Teheran. It has a suspended roof, of aluminium corrugated sheeting. The project was made by Mr. Jawerth, of Stockholm, and the construction was carried out by a Swedish contractor. The hangar is 56 by 30 m, and its structure consists of a number of columns, joined by a triangulated cable framework. These columns are stabilized by guy cables, anchored outside the hangar. Each cable structure has a supporting cable, and another lower one, which serves to stretch the supporting cable. A third cable ties the other two cables together at a number of points. The construction was done by non specialized labour. First the columns were placed in an inclined position, and the cable framework was set up. Then the guy cables were stretched, to place the columns in a vertical position. After this, the cable framework was sufficiently tightened to support the weight of the roof, and, to remain stable under normal conditions. The loads applied to the guy cables were determined by the initial inclination of the columns, and the amplitude of oscillations induced in the cables. The entrance to the hanger has two parts, with three closing units each. An electric motor is provided to close and open them.Para el avión particular del Shah se ha construido, en el aeródromo de Teherán, un hangar con cubierta suspendida, cerrada con chapa ondulada de aluminio.

    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. Outra linha de pesquisa é a utilização de terra diatomácea, um p

    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

    Full Text Available Com o objetivo de testar materiais alternativos para cama de aviário na criação de frangos de corte, foram alojados seis lotes consecutivos, cada um contendo 5.600 aves, apenas fêmeas, distribuídas em 35 boxes. Os tratamentos consistiram de sete tipos de material para cama (maravalha; casca de arroz; sabugo de milho triturado; capim-cameron picado; palhada de soja picada; resto da cultura do milho picado; e serragem, cada um com cinco repetições. Avaliaram-se nas aves o peso corporal médio e o consumo médio de ração e, nas camas, os teores de N, Ca, P e pH. Observaram-se ainda a presença de salmonela, a contagem de oocistos de eimeria na cama e o escore de lesões no intestino das aves ao abate. A utilização dos materiais alternativos avaliados como cama de aviário, por seis lotes consecutivos, como alternativas à maravalha não prejudicou o desempenho de frangos de corte. Esses materiais, após o descarte, por apresentarem valor em minerais superior ao da maravalha, podem ser utilizados na adubação de culturas.Aiming to evaluate alternative materials to be used as broiler litter reutilization, six consecutive lots of 5,600 female broilers were allocated to 35 pens. The treatments consisted of seven types of litter materials: wood shavings, rice husk, ground corncob, chopped camerongrass, chopped soybean straw, chopped corn stalk and sawdust, each one with five replications. In the birds, it was evaluated the average body weight, feed consumption and in the litter, it was evaluated the contents of N, Ca, P and pH. The presence of salmoella, the eimeria oocists counting in the litter, and the gut birds lesions score at slaughter were also observed. The use of alternative materials evaluated as litter, per six concecutive lots, as a alternative for wood shavings did no prejudice the performance of broilers. These materials, by presenting mineral values higher than wood shavings, after discarding, could be used as culture

    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.

    The purpose of this study was to develop and examine a program that was designed to improve the presentation skills of medical school students. The program was implemented in 2-day workshops for 36 third-grade medical students in 2009, using the following procedures in order: needs assessment; an initial group presentation and peer evaluation; an initial self-evaluation with video recording; viewing of a model presentation; a second presentation in a group and peer evaluation; and a second self-assessment. Two types of survey questionnaires were used: a self-evaluation checklist and a questionnaire on workshop satisfaction and confidence of presentation. Eighty-three percent of the students recognized the importance of presentation skills. There were significant differences in 3 factors of self-evaluation-constructing contents, utilizing audio-visual media, and delivery skills- but not with regard to understanding content. In the post workshop satisfaction survey, participants reported that the workshop was helpful in improving their own presentation skills. They also stated that presentation in a group, peer feedback, and video analysis of the recording were helpful. After the workshop, students claimed that their confidence scores in utilizing audio-visual media were the highest. Medical students realize the importance of presentation skills training and workshops in increasing presentation skills and improving confidence in presenting. Video analysis and feedback of each participant's presentation within the group was effective in upgrading the student's presentation skills.

    There are currently no validated guidelines to assess the quality of the content and the delivery style of scientific podium surgical presentations. We have developed a simple, short, and reliable instrument to objectively assess the overall quality of scientific podium presentations. A simple and efficient rating instrument was developed to assess the scientific content and presentation style/skills of the surgical residents' presentations from 1996 to 2013. Absolute and consistency agreement for the different sections of the instrument was determined and assessed overtime, by stage of the project and study design. Intraclass correlation coefficients with 95% confidence intervals were calculated and reported using a mixed-effects model. Inter-rater reliability for both absolute and consistency agreement was substantial for total score and for each of the 3 sections of the instrument. The absolute agreement for the overall rating of the presentations was .87 (.63 to .98) and .78 (.50 to .95), and the consistency agreement was .90 (.70 to .99) and .87 (.67 to .97) for the 2012 and 2013 institutional research presentations, respectively. Rater agreement for evaluating project stage and different study designs varied from .70 to .81 and was consistent over the years. The consistency agreement in rating of the presentation was .77 for both faculty and resident raters. Standardized methodological assessment of research presentations (SHARP) instrument rates the scientific quality of the research and style of the delivered presentation. It is highly reliable in scoring the quality of the all study designs regardless of their stage. We recommend that researchers focus on presenting the key concepts and significant elements of their evidence using visually simple slides in a professionally engaging manner for effective delivery of their research and better communication with the audience.

    Objective There is a paucity of research on patients presenting with uninfected diabetic foot ulcers (DFU) that go on to develop infection. We aimed to investigate the incidence and risk factors for developing infection in a large regional cohort of patients presenting with uninfected DFUs. Methods We performed a secondary analysis of data collected from a validated prospective state-wide clinical diabetic foot database in Queensland (Australia). Patients presenting for their first visit with an uninfected DFU to a Diabetic Foot Service in one of thirteen Queensland regions between January 2012 and December 2013 were included. Socio-demographic, medical history, foot disease history, DFU characteristics and treatment variables were captured at the first visit. Patients were followed until their DFU healed, or if their DFU did not heal for 12-months, to determine if they developed a foot infection in that period. Results Overall, 853 patients were included; mean(standard deviation) age 62.9(12.8) years, 68.0% male, 90.9% type 2 diabetes, 13.6% indigenous Australians. Foot infection developed in 342 patients for an overall incidence of 40.1%; 32.4% incidence in DFUs healed foot deformity (1.4 (1.0–2.0)), female gender (1.5 (1.1–2.1)) and years of age (0.98 (0.97–0.99)) (all pfoot deformity, younger age, female gender and DFUs that have not healed by 3 months after presentation.

    With the aim of advancing the literature on impression management in physical activity settings, we developed a theoretically derived 2 by 2 instrument that was designed to measure different types of context-specific self-presentation motives. Following item generation and expert review (Study 1), the instrument was completed by 206 group exercise class attendees (Study 2) and 463 high school physical education students (Study 3). Our analyses supported the intended factor structure (i.e., reflecting acquisitive-agentic, acquisitive-communal, protective-agentic, and protective-communal motives). We found some support for construct validity, and the self-presentation motives were associated with variables of theoretical and applied interest (e.g., impression motivation and construction, social anxiety, social and achievement goals, efficacy beliefs, engagement). Taken together, the results indicate that the Self-presentation Motives for Physical Activity Questionnaire (SMPAQ) may be useful for measuring various types of self-presentation motives in physical activity settings.

    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.

    Vietnam Atomic Energy Commission (VAEC) was officially established in 1976, and is a national research and development organization in the field of nuclear science and technology for peaceful purposes in Vietnam. Under the VAEC, there are three institutes and one center. Status of main facilities, such as TRIGA MARK II, neutron generator, electron accelerator MT-17, and irradiation facilities are outlined in the paper. At present, the VAEC has a total staff of about 540 persons. The number of staff appears adequate to fulfill the present task on application of isotopes and nuclear techniques. When Vietnam decides to develop nuclear power program, the demand for human resources will be significantly high. During the last five years, Vietnam has been developing and implementing a national regulatory program on Radiation Protection and Nuclear Safety. The Ministry of Science, Technology and Environment (MOSTE) have established independent Vietnam Radiation Protection and Nuclear Safety Authority (VRPA) in 1994. If the Vietnamese Government approves the proposed nuclear power program, human resources training should be a key point for all research and development directions at all revel of personnel. When looking back in the history of formation and development of nuclear science and technology in Vietnam, the international cooperation has played an extremely important role in promoting the program. The exchange of information and direct participation in concrete cooperation activities under the framework of the Forum are expected. (Tanaka, Y.)

    OBJECTIVE Arteriovenous malformations (AVMs) of the brain are a frequent and important cause of intracranial hemorrhage in young adults. Little is known about the molecular-genetic pathomechanisms underlying AVM development. Genes of the NOTCH family control the normal development of vessels and proper arteriovenous specification. Transgenic mice with constitutive expression of active NOTCH4 frequently develop AVMs. Here, the authors report a genetic association study investigating possible associations between NOTCH4 gene polymorphisms and formation and clinical presentation of AVMs. METHODS After PCR amplification and direct DNA sequencing or restriction digests, 10 single-nucleotide polymorphisms (SNPs) of the NOTCH4 gene were used for genotyping 153 AVM patients and 192 healthy controls (i.e., blood donors). Pertinent clinical data were available for 129 patients. Uni- and multivariate single-marker and explorative haplotype analyses were performed to identify potential genetic risk factors for AVM development and for hemorrhagic or epileptic presentation. RESULTS Eleven calculated haplotypes consisting of 3-4 SNPs (most of which were located in the epidermal growth factor-like domain of the NOTCH4 gene) were observed significantly more often among AVM patients than among controls. Univariate analysis indicated that rs443198_TT and rs915895_AA genotypes both were significantly associated with hemorrhage and that an rs1109771_GG genotype was associated with epilepsy. The association between rs443198_TT and AVM bleeding remained significant in the multivariate regression analysis. CONCLUSIONS The authors' results suggest NOTCH4 SNPs as possible genetic risk factors for the development and clinical presentation of AVMs and a role of NOTCH4 in the pathogenesis of this disease.

    Concerns exist around how to talk about eating disorders (EDs) due to evidence that suggests discussing ED symptoms and behaviours may cause or worsen symptoms in vulnerable people. Using expert consensus, we developed a set of guidelines for giving safe community presentations about EDs. Participants with professional ED expertise, and people with lived experience of an ED, were recruited for a Delphi study. N  = 26 panel members rated 367 statements for both a) inclusion in guidelines, and b) their potential to be helpful (increase knowledge, reduce stigma) or harmful (increase stigma, cause/worsen ED symptoms). After each round of the study, statements were classified as endorsed, re-rate, or not endorsed. 208 statements were endorsed by the panel over three rounds. 13 statements were strongly endorsed in the first round, with both people with lived experience and professionals agreeing it is important for presentations to include information on etiology of EDs and to promote help-seeking. Several statements had a high level of disagreement between those with lived experience and professionals, including the idea that presentations should suggest dieting is likely to result in weight gain. The experts were able to develop consensus on a wide range of issues. Panel members, particularly people with lived experience, were sensitive to aspects of presentations that may be harmful to an audience. The guidelines fill an important gap in the literature and provide guidance to those educating the public about EDs; they should, however, be further evaluated to test their efficacy.

    Japan Atomic Energy Agency (JAEA) has started a nuclear forensics (NF) technology development project from JFY 2011, according to the National Statement of Japan in Nuclear Security Summit 2010. This paper will present the progress and future prospects of the development project during JFY 2011 to 2013. The project on NF technology in JAEA includes the development of analytical technologies such as isotope and impurity measurements, morphology analysis, age determination technique, and the prototype of nuclear forensics library (NFL) for future national NFL. Some analytical devices were installed for the analytical technology developments, and various uranium materials produced in JAEA facilities at Ningyo-toge have been measured to verify the analytical technologies. A nuclear material database of the prototype NFL was also developed with brief tools of multivariate analysis and image analysis. The implementation of the analytical technologies, the development of advanced analytical technologies and the system improvements of the prototype NFL will be continued from JFY 2014 in JAEA. The national regime and national response plan are remained as a big challenge to establish the national NF capabilities in Japan. (author)

    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

  18. Present status and potential of group contribution methods for process development

    The development of chemical processes can be performed with the help process simulators. However, for the simulation, besides kinetic data, a reliable knowledge of the pure component and mixture properties is required. Since often 60-80% of the total costs arise in the separation step, a reliable knowledge of the phase equilibrium behaviour of the system to be separated is of special importance. The models for excess Gibbs energy g{sup E} and equations of state allow the calculation of the phase equilibrium behaviour of multicomponent systems using binary information alone. But often, the required binary experimental data are missing. For these systems, a reliable predictive thermodynamic model with a large range of applicabilities would be most desirable. With a view to the development of a powerful predictive method, work on the development of a group contribution method was started in Dortmund 1973. A prerequisite for this work is a large database. Therefore, all published pure component properties, phase equilibrium data, and excess properties were stored in a computerized form. At the same time, experimental techniques for the systematic measurements were built up to measure the missing values. The information stored was used for the development of the group contribution method UNIFAC. The weaknesses of this method were removed with the development of modified UNIFAC. With the introduction of g{sup E}-mixing rules in equations of state, the usage of the 'solution of groups'-concept lead to group contribution equations of state. In combination with electrolyte models, the influence of strong electrolytes on the phase equilibrium behaviour can be taken into account. In this paper, the continuous development, present status, and potential of group contribution methods for the development of chemical processes will be shown.

    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 {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.

    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

    Most of the ambient energy, which was regarded useless in the past, now is under the spotlight. With the rapid developments on low power electronics, future personal mobile devices and remote sensing systems might become self-powered by scavenging energy in different forms from their surroundings. Kinetic energy is one of the promising energy forms in our living environment, e.g., human motions and vibrations. We have proposed an energy flow to clarify the functions of piezoelectric energy harvesting, dissipation, and their effects on the structural damping of vibrating structures. Impedance modeling and analysis were performed. We have designed an improved self-powered switching interface for piezoelectric energy harvesting circuits. With electromagnetic transduction, we also proposed a knee-mounted energy harvester that could convert the mechanical power from knee joints into electricity during walking. On the other hand, we have developed magnetorheological (MR) fluid devices with multiple functions, including rotary actuators and linear dampers. Multifunctional rotary actuator was designed to integrate motor/generator part and MR fluids into a single device. The actuator could function as motor, generator, clutch and brake, with compact size and good energy efficiency. In addition, novel self-sensing MR dampers with power generation, so as to integrate the dynamic sensing, controllable damping and power generation functions, were developed and investigated. Prototypes were fabricated and tested. The developed actuators were promising for various applications. In this paper, related research in energy harvesting done at The Chinese University of Hong Kong and key results will be presented.

    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.

    It is possible that statistical learning (SL) plays a role in almost every mental activity. Indeed, research on SL has grown rapidly over recent decades in an effort to better understand perception and cognition. Yet, there remain gaps in our understanding of how SL operates, in particular with regard to its (im)mutability. Here, we investigated whether participant-related variables (such as age) and task-related variables (such as speed of stimulus presentation) affect visual statistical learning (VSL) in typically developing children. We tested 183 participants ranging in age from 5 to 12 years and compared three speeds of presentation (using stimulus durations of 800, 400 and 200 msecs). A multiple regression analysis revealed significant effects of both age and speed of presentation - after attention during familiarization and gender had been taken into consideration. VSL followed a developmental trajectory whereby learning increased with age. The amount of learning increased with longer presentation times (as shown by Turk-Browne, Jungé & Scholl, 2005, in their study of adults). There was no significant interaction between the two variables. These findings assist in elucidating the nature of statistical learning itself. While statistical learning can be observed in very young children and at remarkably fast presentation times, participant- and task-related variables do impact upon this type of learning. The findings reported here may serve to enhance our understanding of individual differences in the cognitive and perceptual processes that are thought to rely, at least in part, on SL (e.g. language processing and object recognition).

    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.

    Short-pulse x-ray/gamma-ray sources have become indispensable light sources for investigating material science, bio technology, and photo-nuclear physics. In past decades, rapid advancement of high intensity laser technology led extensive progresses in the field of radiation sources based on laser-plasma interactions - x-ray lasers, betatron radiation and Compton gamma-rays. Ever since the installation of a 100-TW laser in 2006, we have pursued the development of ultrashort x-ray/gamma-ray radiations, such as x-ray lasers, relativistic high-order harmonics, betatron radiation and all-optical Compton gamma-rays. With the construction of two PW Ti:Sapphire laser beamlines having peak powers of 1.0 PW and 1.5 PW in 2010 and 2012, respectively [1], we have investigated the generation of multi-GeV electron beams [2] and MeV betatron radiations. We plan to carry out the Compton backscattering to generate MeV gamma-rays from the interaction of a GeV electron beam and a PW laser beam. Here, we present the recent progress in the development of ultrashort x-ray/gamma-ray radiation sources based on laser plasma interactions and the plan for developing Compton gamma-ray sources driven by the PW lasers. In addition, we will present the applications of laser-plasma x-ray lasers to x-ray holography and coherent diffraction imaging. [references] 1. J. H. Sung, S. K. Lee, T. J. Yu, T. M. Jeong, and J.

    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.

    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.

    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. The International Atomic Energy Agency (IAEA) training activities availed 77 % of the total foreign training from 1993 to 1998; Japan follows next at 20 %; and others comprise the remaining 3 %. An approach to training and human resources development, which could reach out to more target trainees, is Distance Learning. In 1998, as a part of a Regional Cooperative Agreement (RCA) and IAEA project, the Philippines participated in the trial of distance learning modules in radiation protection. The distance learning modules were developed at the Australian Nuclear Science and Technology Organization (ANSTO). These modules will

    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

    A sorption cooler uses the Joule-Thomson effect for cooling a gas by expanding it through a flow restriction. The flow of gas is sustained by a compressor consisting of one or more sorption cells, which cyclically adsorb and desorb gas according to the fully reversible process of physical sorption. The technology has been shown to provide active cooling in the cryogenic temperature range without exporting vibrations or electromagnetic interference. Due to full reversibility of the process and the absence of moving parts (apart from check valves, which open and close with a very low frequency), such a cooler has the potential for a very long life and high reliability. This paper starts with a recapitulation of the principles of physical sorption cooling followed by an overview of the strengths and weaknesses of the technology in relation to other space cooling technologies, such as pulse-tube cooling and Stirling cooling. Next, the present status of physical sorption cooling technology is presented based on developments previously and currently being performed by the University of Twente, Dutch Space and Kryoz Technologies. A summary will be given of the various existing demonstrator- and lab-models which have been built, along with an overview of the tests which have so far been performed. The central result of this paper is an assessment of the current Technology Readiness Level (TRL) of various sorption cooler configurations, along with their application range in terms of temperatures, heat loads and mission profile. Finally, an outline is given on the way forward currently being pursued by the developers to achieve full maturity of the technology.

    2007-04-01

    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.

    The importance of nutrition in disease prevention and treatment has gained much attention with the emergence of next generation sequence technologies allowing full-genome sequencing at reduced cost in weeks rather than months. The vast genetic information needs to be efficiently channeled into a useful format to provide applicability for improved health and treatment of disease. Recently, it also led to the birth of nutrigenomics, which facilitates the investigation of the effects of nutrition on gene expression and beyond. At present, a number of studies have showed the effect of nutrition on gene expression in health and disease. For instance, weight loss and as importantly weight keeping has been demonstrated to be efficiently achieved in obesity treatment through personalized diet planning. Likewise, intensive dietary interventions have showed a significant effect on the expression pattern on cancer-related genes in prostate cancer patients. Epigenetic modifications such as DNA methylation, histone modifications, and microRNA-based gene silencing are strongly affected by nutritional intake. Better understanding of the human genome will further accelerate nutrigenomics applications and the development of nutritional modifications including personalized nutrition for our well-being and will also present a strong influence on future drug discovery.

  6. Development of Molecularly Imprinted Polymers to Target Polyphenols Present in Plant Extracts

    Catarina Gomes

    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.

    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.

    In place of the cold war, the destruction of global environment has become to be recognized as the largest threat for mankind. In such circumstance, nuclear fusion has the features that it does not release the substances which cause global warming and acid rain, the fuel resources are contained in seawater, therefore, infinite and distributed uniformly and so on. Nuclear fusion is the fundamental energy source in the sun and space, and aiming at realizing this reaction on the earth as early as possible, now is the time to show the physical and engineering feasibility of nuclear fusion power generation. The progress of the research and development of nuclear fusion is described. At present, the critical plasma condition has been attained for a moment in tokamak type nuclear fusion devices, and the attainment of the self ignition condition is studied. As the methods of realizing nuclear fusion reaction, deuterium-tritium reaction is utilized, and magnetic field confinement and inertia confinement methods are regarded as promising. The performance attained by the various nuclear fusion devices in the world is shown. The elucidation of the factors that decide plasma performance is very difficult. The outline of the ITER project is mentioned. The third stage plan of research and development is explained. The prospect for near future is the start of experiment with the ITER at the beginning of the next century. (K.I.)

    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.

    We have demonstrated the capability of spectral domain optical coherence tomography (SDOCT) system to image full development of mouse embryonic cardiovascular system. Monitoring morphological changes of mouse embryonic heart occurred in different embryonic stages helps identify structural or functional cardiac anomalies and understand how these anomalies lead to congenital heart diseases (CHD) present at birth. In this study, mouse embryo hearts ranging from E9.5 to E15.5 were prepared and imaged in vitro. A customized spectral domain OCT system was used for imaging, with a central wavelength of 1310nm, spectral bandwidth of ~100nm and imaging speed of 47kHz A-scans/s. Axial resolution of this system was 8.3µm in air, and transverse resolution was 6.2 µm with 5X objective. Key features of mouse embryonic cardiovascular development such as vasculature remodeling into circulatory system, separation of atria and ventricles and emergence of valves could be clearly seen in three-dimensional OCT images. Optical clearing was applied to overcome the penetration limit of OCT system. With high resolution, fast imaging speed, 3D imaging capability, OCT proves to be a promising biomedical imaging modality for developmental biology studies, rivaling histology and micro-CT.

    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 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

    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.

  17. 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.

    Conventional label-based contrast enhancement techniques (e.g., fluorescence) frequently modify the genetic makeup of tagged cells, making them poor candidates for use in in-vitro fertilization applications. Instead, we choose a label-free form of contrast, based on interferometric imaging, sensitive to optical path length differences. Compared to, single HeLa cells, typical mammalian ova and embryos are more than an order of magnitude thicker. As a result, regions of large phase variation lead to phase wrapping and an overall reduction in signal intensity occurs due to multiple scattering. These effects manifest themselves in low-spatial frequencies (blurs), with the desired details buried in the background. We present a phase shifting interferometer that yields the derivative of the phase, a quantity whose value is particularly sensitive to local variations and fine details. We demonstrate that our new real-time imaging platform is valuable in measuring the multiday development of bovine embryos. Reconstructing the derivative of the image phase and amplitude, we characterize the motion of previously low-contrast structures, which are relevant for embryo viability tests.

    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.

    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

  1. 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

    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.

    5-ALA-PpIX fluorescence-guided brain tumour resection can increase the accuracy at which cancerous tissue is removed and thereby improve patient outcomes, as compared with standard white light imaging. Novel optical devices that aim to increase the specificity and sensitivity of PpIX detection are typically assessed by measurements in tissue-mimicking optical phantoms of which all optical properties are defined. Current existing optical phantoms specified for PpIX lack consistency in their optical properties, and stability with respect to photobleaching, thus yielding an unstable correspondence between PpIX concentration and the fluorescence intensity. In this study, we developed a set of aqueous-based phantoms with different compositions, using deionised water or PBS buffer as background medium, intralipid as scattering material, bovine haemoglobin as background absorber, and either PpIX dissolved in DMSO or a novel nanoparticle with similar absorption and emission spectrum to PpIX as the fluorophore. We investigated the phantom stability in terms of aggregation and photobleaching by comparing with different background medium and fluorophores, respectively. We characterised the fluorescence intensity of the fluorescent nanoparticle in different concentration of intralipid and haemoglobin and its time-dependent stability, as compared to the PpIX-induced fluorescence. We corroborated that the background medium was essential to prepare a stable aqueous phantom. The novel fluorescent nanoparticle used as surrogate fluorophore of PpIX presented an improved temporal stability and a reliable correspondence between concentration and emission intensity. We proposed an optimised phantom composition and recipe to produce reliable and repeatable phantom for validation of imaging device.

    Science.gov (United States)

    Comber, Joseph D; Philip, Ramila

    2014-05-01

    Major histocompatibility complex class I (MHC-I) presented peptide epitopes provide a 'window' into the changes occurring in a cell. Conventionally, these peptides are generated by proteolysis of endogenously synthesized proteins in the cytosol, loaded onto MHC-I molecules, and presented on the cell surface for surveillance by CD8(+) T cells. MHC-I restricted processing and presentation alerts the immune system to any infectious or tumorigenic processes unfolding intracellularly and provides potential targets for a cytotoxic T cell response. Therefore, therapeutic vaccines based on MHC-I presented peptide epitopes could, theoretically, induce CD8(+) T cell responses that have tangible clinical impacts on tumor eradication and patient survival. Three major methods have been used to identify MHC-I restricted epitopes for inclusion in peptide-based vaccines for cancer: genetic, motif prediction and, more recently, immunoproteomic analysis. Although the first two methods are capable of identifying T cell stimulatory epitopes, these have significant disadvantages and may not accurately represent epitopes presented by a tumor cell. In contrast, immunoproteomic methods can overcome these disadvantages and identify naturally processed and presented tumor associated epitopes that induce more clinically relevant tumor specific cytotoxic T cell responses. In this review, we discuss the importance of using the naturally presented MHC-I peptide repertoire in formulating peptide vaccines, the recent application of peptide-based vaccines in a variety of cancers, and highlight the pros and cons of the current state of peptide vaccines.

    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.

    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.

    2002-01-01

    Framatome ANP has focused its efforts on two development projects in the field of light water reactor technology: the EPR (capacity 1500-1600 MW) and the SWR1000. The main goals pursued in developing the two product lines are: to increase nuclear plant safety even further compared to existing plants and to achieve power generating costs that are competitive with those of fossil-fired power plants. Some key advances made during the development that are particularly characteristic of the EPR and SWR are discussed. For the EPR the main safety systems are: double wall containment, containment heat removal system, four train redundancy for main safeguard systems etc. The physical separation of the systems as regards ventilation as well as by concrete walls rules out the possibility of multiple failures caused by fire, flooding or sabotage. In case od a core-melting accident the specially developed depressurization system reduces primary system pressure to < 20 bar. Various PSA have been conducted resulting in the development of a well-balanced system and component designs and avoiding dominant accident sequences from power and shutdown states.One major feature of the SWR 1000 are the passive safety systems, developed, tested and integrated into the design. They are: Containment cooling condensers for heat removal; Safety Relief Valves; Emergency condensers for heat removal from the RPV; Flooding lines for passive core flooding in the event of a LOCA; Drywell flooding line (core-melt accident). Accidents can be controlled both by active and passive systems. PSA has been also conducted. Some economic aspects are discussed in the paper

    This is a summary report on the results of the Detector R and D work, which we have been carrying out these three years, under the Japan-U.S. collaboration on High Energy Physics. It is clear that there have been already many considerable progress and outputs in the activities, some of which are already applied to the actual detectors in various ways. It is foreseeable that more extensive development will be realized. It should also be better to emphasize that these detector R and D efforts will be very important for the further development of high energy physics in the near future. (author)

  2. The IAEA Standards for the Radioactive Discharge Control: Present Status and Future Development

    International Nuclear Information System (INIS)

    2004-01-01

    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

    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.

    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.

    Energy Technology Data Exchange (ETDEWEB)

    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. (JDB)

    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.

    Sarlos, G.; Bucher, K.H.

    1990-01-01

    Research, Development and Design of Gas-cooled Reactors have already a long and well accepted tradition in Switzerland. These activities began with the design and construction of an experimental gas-cooled power station of 30 MW by the Swiss industry in the early sixties. Swiss industry restricted themselves to the development and the supply of reactor systems and components only. Through extensive research and the participation in various international projects such as AGR, AVR, FSV, THTR, HHT, HTR etc., it was possible to gain valuable know-how, which qualified the Swiss industry as reliable manufactures of reactor components and enabled them to render all kinds of engineering services for nuclear power plants. In order to utilize the existing vast experience, the companies concerned and the PSI agreed in 1979 to join as partners and established the 'Swiss Community for the Development of Nuclear Technology' called IGNT. Partners of IGNT are ABB, Baden; Sulzer, Winterthur; B + G, Lausanne; EWI, Zuerich; Colenco, Baden; and the Swiss Federal Institute for Reactor Research (PSI). IGNT represents and coordinates the activities of the partners, especially in the field of the high temperature gas-cooled reactors. As a consequence of this partnership, the members of IGNT engaged themselves in the development of the HTR-Technology in general and particularly in the design of the HTR-500. Another project which was pursued in Switzerland over the recent years, is the gascooled heating reactor, a small pebble-bed HTR of 10 to 20 MW for district heating purposes. In 1988 work on this project has been terminated for political reasons, but will probably be taken up in 1990/91. (author)

    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.

    2017-11-16

    GSK3 has gained a considerable attention of researchers in the late 1970s as an inevitable drug target to treat diabetes. Furthermore, it was found to have a key role in the development of diseases like cancer and neurodegeneration (ND). A broad spectrum of GSK3 inhibitors have been discovered from time to time in order to curb these diseases. Inhibition of GSK3 by insulin boosts the dephosphorylation of glycogen synthase, hence its activation to convert UDP glucose into glycogen. Lack of insulin and insulin-resistance is supposed to be the cause of type 2 diabetes (Diabetes mellitus). Additionally, GSK3 stabilizes the components of beta-catenin complex, hence promotes oncogenesis. Phosphorylation of GSK3 by Akt and some other kinases also favours the carcinogenesis. However, in some cases GSK3 has tumor supressing character. GSK3 has been found to have a prominent role in the formation of amyloid plaques and neurofibrillary tangles (abnormal protein accumulations) which are the main suspects of Alzheimer's disease (AD). GSK3 inhibitors have been reported to have amyloidbeta disaggregation property and have been found to promote the adult hippocampal neurogenesis in vivo as well as in vitro. This manuscript thoroughly reviews the involvement of GSK3 in diabetes, cancer and ND. Furthermore, development of GSK3 inhibitors as antidiabetes, anticancer and antineurodegenerative agents focusing mainly on lead optimization has been discussed.

    Full Text Available Nucleoprotein (N gene from rabies virus (RABV is a useful sequence target for variant studies. Several specific RABV variants have been characterized in different mammalian hosts such as skunk, dog, and bats by using anti-nucleocapsid monoclonal antibodies (MAbs via indirect fluorescent antibody (IFA test, a technique not available in many laboratories in Mexico. In the present study, a total of 158 sequences of N gene from RABV were used to design eight pairs of primers (four external and four internal primers, for typing four different RABV variants (dog, skunk, vampire bat, and nonhematophagous bat which are most common in Mexico. The results indicate that the primer and the typing variant from the brain samples, submitted to nested and/or real-time PCR, are in agreement in all four singleplex reactions, and the designed primer pairs are an alternative for use in specific variant RABV typing.

    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.

  14. Beyond Ti-Zr-V: present development on thin-film coatings for beam pipes

    2008-01-01

    Since 1997, Ti-Zr-V thin films have been studied to provide a solution to the problems of both pressure distribution and electron cloud build-up in beam pipes. Nowadays, this material is coated on the whole inner surface of vacuum chambers providing large pumping speed, low degassing rate and secondary electron yield. These favourable characteristics are obtained after heating in vacuum at temperatures higher than 180 °C. Unfortunately, heating at such temperatures is not always possible for the future CERN projects: in some cases, magnet designs impose lower heating temperatures; in other cases, heating is not allowed at all, as for most of the existing SPS vacuum chambers. To overcome these limitations, two lines of development have been drawn; if pursed successfully, they will allow the production of both NEG films with lower activation temperature (150 °C being our target) and films or surface treatments providing low secondary electron yield without any heating.

    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

    Full Text Available BACKGROUND: Naturally acquired malaria immunity has many determinants and, in the absence of immunological markers of protection, studies assessing malaria incidence through clinical endpoints remain an approach to defining immunity acquisition. We investigated the role of age in disease incidence and the effects of chemoprophylaxis on clinical immunity development to Plasmodium falciparum during a randomised controlled trial. METHODS AND FINDINGS: A total of 415 Tanzanian infants were randomly assigned to receive weekly malaria prophylaxis with Deltaprim (3.125 mg of pyrimethamine plus 25 mg of dapsone or placebo between the ages of 2 and 12 mo. Children were followed up until 4 y of age. Uncomplicated febrile malaria, severe malaria, and anaemia morbidity were assessed through hospital-based passive surveillance. Compared with the group of control participants, there was a marked reduction in the incidence of clinical malaria, severe malaria, and anaemia in the group of children who had received chemoprophylaxis during the first year of life. After discontinuing the intervention, there was a significant increase in the incidence of clinical malaria for 2 y. The cumulative rates of clinical malaria, by age 4 y, were slightly higher in the group of children who had previously received chemoprophylaxis: 3.22 episodes versus 3.02 episodes in the group of control participants; rate difference 0.20 (95% confidence interval [CI]: -0.21 to 0.59. By age 4 y, the cumulative rates of severe malaria, however, were slightly lower in chemosuppressed children (0.47 versus 0.59 (rate difference -0.12 [95% CI: -0.27 to 0.03]. The number of episodes of anaemia was also slightly lower in chemosuppressed children by age 4 y: 0.93 episodes (95% CI: 0.79 to 0.97 versus 1.12 episodes in the group of control participants (95% CI: 0.97 to 1.28 (rate difference -0.19 [95% CI: -0.40 to 0.01], respectively. CONCLUSIONS: Reducing exposure to P. falciparum antigens through

    A lot of data were reported about monitoring patients with inflammatory bowel disease, with varying degrees of practical applicability. Concerning the evaluation of disease activity, it was established that objective assessments are needed. Among the techniques that we use, although endoscopy is undoubtedly the reference standard, a lot of data were presented regarding less invasive techniques. The importance of MRIs, CTs and ultrasounds (with some variations) was thus reiterated. The importance of fecal calprotectin is also reiterated, not only for colon disease, but probably small intestine disease as well. Regarding treatment monitoring, a great deal was reported about anti-TNF therapy, demonstrating again its potential role when properly used. In addition to results with infliximab, results with adalimumab were reported as very consistent. For colon cancer prevention, it seems that the clinical guidelines are achieving their objective. It also seems clear that we must improve conventional endoscopic techniques. Finally, there are other aspects that need to be considered when monitoring our patients, such as adequate sleeping patterns, anxiety or depression. Copyright © 2014 Elsevier España, S.L.U.

    1989-02-01

    National Electrostatics Corp. has manufactured 79 ion beam systems. 17 of these Pelletron systems were designed with MeV ion implantation capability as a primary objective. Of these system, 8 were designed specifically for production ion implantation with a maximum beam energy of 4 MeV. For research applications, ion beam masses from carbon through gold have been accelerated with a maximum observed energy of 38 MeV from a 3 MV tandem S-series Pelletron. This paper will present performance charts which describe the observed ion beam capabilities of existing 3 MV tandem Pelletrons. In addition, the performance of the new high current, four charging chain, S-Series accelerator, currently in manufacture, will be given. A new 4 MV tandem S-Series Pelletron has been proposed, its expected capabilities will be stated. The NEC electrostatics raster scanner which is in use for MeV implantation provides uniform deposition at a maximum scan angle of ± 3.0 ° for 4 MeV doubly charged ions. The output wave form at ±10 kV scanning potential will be shown.

  19. Development of an add-on kit for scanning confocal microscopy (Conference Presentation)

    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.

  20. The present stage of development of ionizing radiation treatment in France

    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

    The design and function of leaf venation are important to plant performance, with key implications for the distribution and productivity of ecosystems, and applications in paleobiology, agriculture and technology. We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance. We describe the development and plasticity of leaf venation and its adaptation across environments globally, and a new global data compilation indicating trends relating vein length per unit area to climate, growth form and habitat worldwide. We synthesize the evolution of vein traits in the major plant lineages throughout paleohistory, highlighting the multiple origins of individual traits. We summarize the strikingly diverse current applications of leaf vein research in multiple fields of science and industry. A unified core understanding will enable an increasing range of plant biologists to incorporate leaf venation into their research. © 2013 The Authors New Phytologist © 2013 New Phytologist Trust.

    The emerging field of bioelectronic medicine seeks methods for deciphering and modulating electrophysiological activity in the body to attain therapeutic effects at target organs. Current approaches to interfacing with peripheral nerves and muscles rely heavily on wires, creating problems for chronic use, while emerging wireless approaches lack the size scalability necessary to interrogate small-diameter nerves. Furthermore, conventional electrode-based technologies lack the capability to record from nerves with high spatial resolution or to record independently from many discrete sites within a nerve bundle. We recently demonstrated (Seo et al., arXiV, 2013; Seo et al., Neuron, 2016) "neural dust," a wireless and scalable ultrasonic backscatter system for powering and communicating with implanted bioelectronics. There, we showed that ultrasound is effective at delivering power to mm-scale devices in tissue; likewise, passive, battery-less communication using backscatter enabled high-fidelity transmission of electromyogram (EMG) and electroneurogram (ENG) signals from anesthetized rats. In this talk, I will review recent developments from my group and collaborators in this area.

    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.

  4. Radionuclide ventriculography (equilibrium gated blood pool scanning) - its present clinical position and recent developments

    1988-01-01

    Myocardial scanning (MS) and radionuclide ventriculography (RNV) aim in two completely different directions: RNV tries to image heart motion, that is, mechanical (pump) function, and therefore belongs to the group of first-order functional imaging (FI, imaging mechanical function), whereas MS is based on myocardial metabolism, and therefore can be attributed to third-order functional imaging (metabolism). This statement is relevant for the assessment of the clinical position of RNV: Third-order (metabolism) functional imaging is the domain of nuclear medicine (NM), whereas first-order FI has to face the competition of alternative noninvasive procedures such as ultrasound (US), digital subtraction angiography (DSA), computer tomography (CT), and nuclear magnetic resonance (NMR). The domain of RNV includes stages two (acute infarction) and three (postinfarction period) of coronary arterial disease (CAD). The advantageous combination of quantitative data on global, left ventricular (LV) function and imaging of regional motion ensures the superiority of RNV over US. However, RNV is inferior to MS in physical examinations in the preinfarction stage of CAD, whereas US is clearly inferior to both NM procedures. Recent progress could be attained by gated SPECT (GASPECT). A proposal is presented for simplification of this time-consuming procedure. Technetium-labeled isonitriles offer the chance for the combination of 'perfusion-motion' imaging of the myocardium. However, even standard RNV offers new possibilities. The multitude of parameters produced by quantitation has not yet been exploited completely. This can be done by discriminant analysis. The computer finds out an optimal subset from the whole set of parameters for the solution of a significant clinical problem. The software 'learns' to find the 'label' of a special pathognomonic entity. This computer work is supported by a relational data bank (Oracle) and an optical disk. (orig./MG)

    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

    1979-05-01

    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

  7. The present, past and future of the study of intellectual disability: challenges in developing countries.

    Science.gov (United States)

    Parmenter, Trevor R

    2008-01-01

    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.

    2007-05-01

    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.

    Array-CGH is considered as the first-tier investigation used to identify copy number variations. Right now, there is no available data about the genetic etiology of patients with development delay/intellectual disability and congenital malformation in East Africa. Array comparative genomic hybridization was performed in 50 Rwandan patients with development delay/intellectual disability and multiple congenital abnormalities, using the Agilent's 180 K microarray platform. Fourteen patients (28%) had a global development delay whereas 36 (72%) patients presented intellectual disability. All patients presented multiple congenital abnormalities. Clinically significant copy number variations were found in 13 patients (26%). Size of CNVs ranged from 0,9 Mb to 34 Mb. Six patients had CNVs associated with known syndromes, whereas 7 patients presented rare genomic imbalances. This study showed that CNVs are present in African population and show the importance to implement genetic testing in East-African countries.

    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.

    Background Array-CGH is considered as the first-tier investigation used to identify copy number variations. Right now, there is no available data about the genetic etiology of patients with development delay/intellectual disability and congenital malformation in East Africa. Methods Array comparative genomic hybridization was performed in 50 Rwandan patients with development delay/intellectual disability and multiple congenital abnormalities, using the Agilent’s 180 K microarray platform. Results Fourteen patients (28%) had a global development delay whereas 36 (72%) patients presented intellectual disability. All patients presented multiple congenital abnormalities. Clinically significant copy number variations were found in 13 patients (26%). Size of CNVs ranged from 0,9 Mb to 34 Mb. Six patients had CNVs associated with known syndromes, whereas 7 patients presented rare genomic imbalances. Conclusion This study showed that CNVs are present in African population and show the importance to implement genetic testing in East-African countries. PMID:25016475

    Up to now, only a single adenovirus (AdV) isolate seemingly specific for pigeons, hence named pigeon AdV-1 (PiAdV-1), has been characterised at DNA sequence level. In the present work, the prevalence and diversity of AdVs occurring in domestic pigeon were examined by a survey performed on randomly collected samples using a very efficient, consensus nested PCR targeting the viral DNA polymerase gene. The newly detected viruses were characterised by sequencing and phylogeny analysis. Amplification of additional genome fragments was attempted by the use of several other PCR methods aiming at the hexon gene. During a 4-year survey, samples from dead or live, healthy pigeons originating from 27 lofts were examined in Hungary. Almost 50% of the samples (48 out of 97) proved to be positive for AdV. Sequence analysis revealed the presence of four hitherto unknown pigeon AdV types. PiAdV-1 was also identified in one sample. Two novel viruses named PiAdV-2 and -3 were found to belong to the genus Aviadenovirus, and two other novel types (PiAdV-4 and -5) to the genus Siadenovirus. This is the first report on the occurrence of siadenoviruses in birds belonging to the order Columbiformes. Approximately two-thirds of the PiAdV-2 genome was sequenced and analysed.

    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.

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

    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.

    Clinical practice guidelines are one of the foundations of efforts to improve healthcare. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearinghouses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this second paper, we discuss issues of identifying and synthesizing evidence: deciding what type of evidence and outcomes to include in guidelines; integrating values into a guideline; incorporating economic considerations; synthesis, grading, and presentation of evidence; and moving from evidence to recommendations.

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

    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.

    To implement a mock rounds activity designed to introduce and develop patient presentation skills in pharmacy students. The sample population included third-year pharmacy students enrolled at the University of New Mexico (UNM) and Virginia Commonwealth University (VCU) during Fall 2011, 2012, and 2013. A mock rounds activity was developed and implemented in the Pharmaceutical Care Lab setting. Students were assigned an infectious disease case and asked to create an assessment and plan to present orally to an acting preceptor in a small group laboratory setting. Summative assessment of student performance was evaluated using a standardized rubric. A total of 621 students (VCU: 371; UNM: 250) from both universities participated in the mock rounds activity. Data was collected using the rubric. Students scored highest in the areas of respectfulness (94.8% exceeds expectations) and completion time (86.9% exceeds expectations). The lowest ratings were in the areas of logical flow and organization (73.7% exceeds expectations) and ability to answer preceptors' questions (73.3% exceeds expectations). A simulated mock rounds activity enabled students to practice patient case presentation skills and receive summative feedback prior to Advanced Pharmacy Practice Experiences.

    Immune molecules have been discovered recently to play critical roles in the development, function, and plasticity of the cerebral cortex. MHC class I (MHCI) molecules are expressed in the central nervous system and regulate activity-dependent refinement of visual projections during late postnatal development. They have also been implicated in neurodevelopmental diseases such as schizophrenia and autism. Despite the excitement generated by these unique roles for immune proteins in the brain, little is known about how these molecules regulate cortical connections. The first step toward elucidating the mechanism is to identify the spatial and temporal distribution of MHCI proteins throughout development. Using a pan-specific antibody that recognizes many MHCI variants for biochemistry and immunohistochemistry, we found that MHCI proteins are expressed in the rat visual cortex at all ages examined-during the peak of synaptogenesis, the critical period of synaptic refinement, and adulthood. Their abundance in the cortex peaked during early postnatal development, declining during periods of plasticity and adulthood. In contrast to current assumptions, pre- and postembedding immunogold electron microscopy (EM) revealed that MHCI proteins were present both pre- and postsynaptically at all ages examined. They were often found in the postsynaptic density and were closely associated with synaptic vesicles in the presynaptic terminal. These results suggest a previously undescribed model in which MHCI molecules function on both sides of the synapse to regulate connectivity in the mammalian visual cortex before, during, and after the establishment of connections.

    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. Potentiation of response to insulin and anti-insulin action by two human pituitary peptides in lean agouti A/a, obese yellow Avy/A, and C57BL/6J-ob/ob mice.

    Insulin-like and anti-insulin effects of human growth hormone (hGH) were examined by determining the effects of two peptides representing portions of the hGH molecule in lean agouti A/a and obese yellow Avy/A and ob/ob mice. The peptides were the amino terminal segment, residue 1-43 (hGH1-43), which has been shown to potentiate the response to insulin and another peptide, hyperglycemic peptide (HP), with unknown structure, which has anti-insulin activity. The anti-insulin component is an acidic low molecular weight peptide which co-purifies with hGH but was not recognized by antibodies to intact hGH and did not cross-react with anti-hGH1-43 antiserum. The purpose of these studies was to further understand the multiple actions of hGH and its acute and chronic effects on response to insulin. Injections of hGH1-43 dramatically enhanced the effect of insulin on glucose clearance of obese yellow Avy/A and ob/ob mice and increased the insulin-stimulated glucose oxidation in adipose tissue of yellow mice, but had no direct effect on blood glucose or insulin levels of either genotype. Administration of HP to obese yellow mice produced hyperglycemia and suppressed serum insulin concentrations. Tissues from lean agouti and obese yellow mice treated with HP in vitro showed decreased basal and insulin-stimulated glucose oxidation as well as decreased 14C incorporation into lipids. Chronic treatment of obese yellow and ob/ob mice with HP increased fasting blood glucose and impaired glucose tolerance. The effect of HP was more pronounced in obese yellow mice and the ob/ob mice were more sensitive to the diabetogenic actions of intact hGH. These data provide further evidence for the existence of two opposing biologic activities derived from disparate amino acid sequences in hGH. Additionally, the data indicate that assays using obese yellow Avy/A mice can distinguish the effects of hGH from those of the individual peptides to a greater degree than assays using obese ob/ob mice.

    Full Text Available Escherichia coli is one of the most important bacterial avian pathogens and a common inhabitant of the gastrointestinal tract of animals. Most pathogenic E. coli can not be differentiated biochemically or by classic microbiologic methods. Molecular typing methods, particularly PCR, facilitated epidemiological and ecological studies of bacteria. Here we describe the application of a random amplified polymorphic DNA- polymerase chain reaction (RAPD-PCR for molecular genetic differentiation of E. coli isolates in Iran. In this study 58 E. coli isolates including 4 standard strains, 3 food originated isolates, 33 avian isolates, 8 isolates form diarrheic calves and 10 isolates from unweaned diarrheic lambs were analyzed by RAPD-PCR using primer 1247(5/-AAG AGC CCG T-3/. The RAPD analysis showed that these isolates could be grouped into 33 RAPD types and avian isolates were discriminated into 29 genotypes. It was shown that the primer could not differentiate E. coli isolated from lambs. Discriminatory index for entire isolates was 0.912 and for avian isolates was 0.990. We concluded that RAPD-PCR can be used as a method for molecular differentiation of E. coli isolates.Escherichia coli é um dos patógenos aviários mais importantes e um habitante comum do trato gastrointestinal de animais.

    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.

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

    Hrvoje Petković

    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.

    The federal environmental review process under the National Environmental Policy Act of 1969 (NEPA) can be complex and time consuming. Currently, a geothermal developer may have to complete the NEPA process multiple times during the development of a geothermal project. One mechanism to reduce the timeframe of the federal environmental review process for activities that do not have a significant environmental impact is the use of Categorical Exclusions (CXs), which can exempt projects from having to complete an Environmental Assessment or Environmental Impact Statement. This study focuses primarily on the CX process and its applicability to geothermal exploration. In this paper, we: Provide generalized background information on CXs, including previous NEPA reports addressing CXs, the process for developing CXs, and the role of extraordinary circumstances; Examine the history of the Bureau of Land Management's (BLM) geothermal CXs; Compare current CXs for oil, gas, and geothermal energy; Describe bills proposing new statutory CXs; Examine the possibility of standardizing geothermal CXs across federal agencies; and Present analysis from the Geothermal NEPA Database and other sources on the potential for new geothermal exploration CXs. As part of this study, we reviewed Environmental Assessments (EAs) conducted in response to 20 geothermal exploration drilling permit applications (Geothermal Drilling Permits or Notices of Intents) since the year 2001, the majority of which are from the last 5 years. All 20 EAs reviewed for this study resulted in a Finding of No Significant Impact (FONSI). While many of these FONS's involved proponent proposed or federal agency required mitigation, this still suggests it may be appropriate to create or expand an exploration drilling CX for geothermal, which would have a significant impact on reducing geothermal exploration timelines and up-front costs. Ultimately, federal agencies tasked with permitting and completing

    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

    Although high risk HPVs are associated with an increased risk of prostate cancer it is not known if they have a causal role. The purpose of this study is to investigate the potential role of human papilloma viruses (HPVs) in prostate cancer. The aims are (i) to investigate the presence and confirm the identity of high risk HPVs in benign prostate tissues prior to the development of HPV positive prostate cancer in the same patients, and (ii) to determine if HPVs are biologically active. We used polymerase chain reaction (PCR) to identify HPVs in specimens from 52 Australian men with benign prostate biopsies who 1 to 10 years later developed prostate cancer. Immunohistochemistry (IHC) was used to assess the expression of HPV E7 oncoproteins, cytokeratin and prostate specific antigen (PSA). We used RNASeq data from The Cancer Genome Atlas (TCGA) to identify possible HPV RNA sequences in prostate cancer. HPV screening using standard PCR was conducted on 28 of the 52 sets of benign and later prostate cancers. HPV L1 genes were identified in 13 (46%) benign and 8 (29%) of 28 later prostate cancers in the same patients. HPV E7 genes were identified in 23 (82%) benign and 19 (68%) of 28 subsequent prostate cancers in the same patients. The same HPV types were present in both the benign and subsequent prostate cancers in 9 sets of specimens. HPV type 16 was identified in 15% of benign and 3% of prostate cancers. HPV type 18 was identified in 26% of benign and 16% of prostate cancers. Small numbers of HPV types 45, 47, 76 and 115 were also identified. High confidence RNA-Seq evidence for high risk HPV types 16 and 18 was identified in 12 (2%) of the 502 TCGA prostate cancer transcriptomes. High risk HPV E7 oncoprotein was positively expressed in 23 (82%) of 28 benign prostate specimens but only in 8 (29%) of 28 of the later prostate cancer specimens. This difference is statistically significant ( p  = 0.001). Prostate specific antigen (PSA) was more highly expressed in 26

    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.

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

    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.

    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.

    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

    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

  11. Selection of quality assurance programme levels for nuclear power plants. Present practice in Canada and future developments

    Thomas, R.A.

    1982-01-01

    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.)

    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.

    Cerebral small vessel disease (SVD) is associated with late-onset depression and increases the risk for depression after stroke. We aimed to investigate baseline predictors of depression after long-term follow-up in patients with SVD, initially presenting with first-ever lacunar stroke, free of depression and cognitive impairment. A total of 294 patients with SVD were evaluated 3-5 years after the qualifying event. We analyzed baseline demographic data, vascular risk factors, functional status expressed as a score on modified Rankin Scale (mRS), cognitive status, presence of depression, total number of lacunar infarcts and severity of white matter hyperintensities (WMH) on MRI with Age-Related White Matter Changes scale total score (tARWMC) and Fazekas scale periventricular and deep subcortical scores. On follow-up, depression was registered in 117 (39.8%) SVD patients. At the baseline, patients with depression compared with non-depressed were older (64.4 vs 60.9 years; p = 0.007), had higher mRS score (2.8 ± 0.7 vs 1.5 ± 0.7; p depressed patients more frequently exhibited cognitive decline (75.2% depressed vs 56.5% non-depressed; p = 0.003). No difference was detected in risk factor frequency between groups. Multivariate Cox regression analysis adjusted by age and gender revealed independent predictors of depression: baseline mRS >2 (HR 2.17, 95%CI 1.74-2.72; p cognitive decline on follow-up (HR 1.80, 95%CI 1.12-2.89; p = 0.015). Baseline functional status and severity of WMH and development of cognitive decline predict the occurence of late-onset depression in patients with SVD. Copyright © 2015 John Wiley & Sons, Ltd.

    In the spirit of Dr. Haggerty's teachings, we present an overview of our work to improve care for children with asthma in the context of 3 lessons learned: 1) the importance of providing integrated services across disciplinary boundaries for children with chronic illness, 2) the need to move from a care model focused only on the individual child to a model focused on the child, family, and community, and 3) the need to expand beyond the local community and take a broad perspective on improving health on a national level. The goal of our program is to develop sustainable models to overcome the multiple obstacles to effective preventive care for urban children with asthma. The primary intervention for our original School-Based Asthma Therapy program was directly observed administration of preventive asthma medications in school (with dose adjustments on the basis of National Heart, Lung, and Blood Institute guidelines). We found that children who received preventive medications in school through directly observed therapy had improved outcomes across multiple outcome measures. Our subsequent asthma programs have focused on dissemination and sustainability, with the incorporation of communication technology to enhance the system of care. We are currently testing the 'School-Based Telemedicine Enhanced Asthma Management' program, including 400 children with persistent asthma from the Rochester City School District. This program includes directly observed administration of preventive asthma medication at school, and school-based telemedicine to assure appropriate evaluation, preventive medication prescription, and follow-up care. It is designed to implement and sustain guideline-based asthma care through existing community infrastructure, and could serve as a model for the integration of services in rural as well as urban communities.

    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.

    A novel method, an in situ autologous whole-cell cancer vaccine (inCVAX), is being developed by Immunophotonics, Inc., for the treatment of metastatic cancers. inCVAX combines phototherapy and immunotherapy to potentially induce a systemic anti-tumor immune response in the hosts. Immunophotonics and its academic partners have spent years conducting nonclinical research, developing CMC techniques and conducting clinical research. In 2015 the company initiated a late-stage (II/III) clinical trial in South America for advanced breast cancer patients. The process of developing the inCVAX approach from a laboratory setting into clinical trials requires significant efforts from a group of dedicated engineers, scientists, and physicians.

    he National Energy Technology Laboratory (NETL) under the Department of Energy (DOE) Fossil Energy (FE) Program is leading the effort to not only develop near zero emission power generation systems, but to increaser the efficiency and availability of current power systems. The overarching goal of the program is to provide clean affordable power using domestic resources. Highly efficient, low emission power systems can have extreme conditions of high temperatures up to 1600 oC, high pressures up to 600 psi, high particulate loadings, and corrosive atmospheres that require monitoring. Sensing in these harsh environments can provide key information that directly impacts process control and system reliability. The lack of suitable measurement technology serves as a driver for the innovations in harsh environment sensor development. Advancements in sensing using optical fibers are key efforts within NETL's sensor development program as these approaches offer the potential to survive and provide critical information about these processes. An overview of the sensor development supported by the National Energy Technology Laboratory (NETL) will be given, including research in the areas of sensor materials, designs, and measurement types. New approaches to intelligent sensing, sensor placement and process control using networked sensors will be discussed as will novel approaches to fiber device design concurrent with materials development research and development in modified and coated silica and sapphire fiber based sensors. The use of these sensors for both single point and distributed measurements of temperature, pressure, strain, and a select suite of gases will be addressed. Additional areas of research includes novel control architecture and communication frameworks, device integration for distributed sensing, and imaging and other novel approaches to monitoring and controlling advanced processes. The close coupling of the sensor program with process modeling and

    To investigate the pattern of presentation, severity, factors responsible for delayed presentation and outcome of breast cancer in patients presenting to a teaching hospital of Jamshoro. Methods: It's a prospective descriptive study of 103 malignant breast lumps treated at a tertiary care teaching hospital over a period of 8 years. All patients were admitted through Outpatients department and were thoroughly examined and investigated. Treatment offered was based on triple assessment and ranged from lumpectomy to toilet mastectomy depending upon the stage of disease. The variables studied were recorded on a proforma and analyzed on SPSS version 12 for measuring frequencies and using Chi square test where applicable. Results: The mean age of the study population was 39.17 +- 6.019 years and a range of 22 to 54 years. The frequency of advanced malignancy was alarmingly high in younger patients. Intra-ductal carcinoma was the commonest tumour in 93 (90%) patients, while the remaining included lobular and Paget's disease. The high figures of advanced disease at presentation is attributed to lack of knowledge and education, poverty and local customs of women not exposing themselves even to the physicians. In addition, there is a substantial delay in the referral of patients from under privileged, remote areas where patients continue to receive symptomatic treatment till such time that disease becomes incurable. Conclusion: Advanced breast disease is common in younger patients belonging to underprivileged and remote rural areas. Great efforts are required to educate people so as to make early diagnosis possible. (author)

    Near infrared (NIR) emitting quantum dots based on copper indium chalcogenides present unique optical properties for in vivo fluorescence imaging. Here we present the synthesis of CuIn(S,Se)2/ZnS core/shell QDs with 30-50% quantum yield in the NIR range. These nanoprobes are solubilized in water using a block copolymer surface ligand composed of multiple binding groups for enhanced stability and zwitterionic groups for solubility and minimized nonspecific adsorption. They present limited toxicity compared to heavy metal-containing QDs. These versatile nanoprobes can be directly injected in the peritumoral region for sentinel lymph node imaging. We also demonstrate their vectorization with RGD peptides or their incorporation in folic acid-functionalized silica particles to target specific cancer cells. Their long fluorescence lifetime enables rejection of autofluorescence using time-gated detection. This considerably enhances the sensitivity of in vivo fluorescence imaging. These QDs have been used for long term labeling of cancer cells ex vivo. Following reinjection of these cells, time-gated detection enables in vivo imaging of these cancer cells in the blood stream at the single cell level. Finally, these QDs can be doped with paramagnetic manganese ions to provide multimodal contrast in both fluorescence and magnetic resonance imaging.

    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

    Zebrafish, an auditory specialist among fish, offer analogous auditory structures to vertebrates and is a model for hearing and deafness in vertebrates, including humans. Nevertheless, many questions remain on the basic mechanics of the auditory pathway. Phase-sensitive Optical Coherence Tomography has been proven as valuable technique for functional vibrometric measurements in the murine ear. Such measurements are key to building a complete understanding of auditory mechanics. The application of such techniques in the zebrafish is impeded by the high level of pigmentation, which develops superior to the transverse plane and envelops the auditory system superficially. A zebrafish double mutant for nacre and roy (mitfa-/- ;roya-/- [casper]), which exhibits defects for neural-crest derived melanocytes and iridophores, at all stages of development, is pursued to improve image quality and sensitivity for functional imaging. So far our investigations with the casper mutants have enabled the identification of the specialized hearing organs, fluid-filled canal connecting the ears, and sub-structures of the semicircular canals. In our previous work with wild-type zebrafish, we were only able to identify and observe stimulated vibration of the largest structures, specifically the anterior swim bladder and tripus ossicle, even among small, larval specimen, with fully developed inner ears. In conclusion, this genetic mutant will enable the study of the dynamics of the zebrafish ear from the early larval stages all the way into adulthood.

    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.

    The objective of the present work was to study the pathological changes in various organs and tanatogenesis associated with Mallory-Weiss syndrome making use of the forensic medical and clinical materials. It was shown that the main cause of unrestrained vomiting resulting from alcoholic intoxication and leading to perfusive bleeding is not only the direct action of ethanol and surrogate alcohol on gastroesophageal mucosa and induced thrombocytopenia. Another cause may be brain oedema with subsequent cerebral herniation and irritation of the pseudobulbar centres responsible for the initiation of the vomiting reflex. The authors propose recommendations for forensic medical diagnostics of the cases of such hemorrhage.

    The ciliate Oxytricha trifallax maintains two genomes: a germline genome that is active only during sexual conjugation and a transcriptionally active, somatic genome that derives from the germline via extensive sequence reduction and rearrangement. Previously, we found that long noncoding (lnc) RNA "templates"-telomere-containing, RNA-cached copies of mature chromosomes-provide the information to program the rearrangement process. Here we used a modified RNA-seq approach to conduct the first genome-wide search for endogenous, telomere-to-telomere RNA transcripts. We find that during development, Oxytricha produces long noncoding RNA copies for over 10,000 of its 16,000 somatic chromosomes, consistent with a model in which Oxytricha transmits an RNA-cached copy of its somatic genome to the sexual progeny. Both the primary sequence and expression profile of a somatic chromosome influence the temporal distribution and abundance of individual template RNAs. This suggests that Oxytricha may undergo multiple rounds of DNA rearrangement during development. These observations implicate a complex set of thousands of long RNA molecules in the wiring and maintenance of a highly elaborate somatic genome architecture. © 2017 Lindblad et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

    Necessity to decrease anthropogenic environmental pollution puts a task of development of HV accelerators for introduction of nature conservation technologies in commercial scale. 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

    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)

    2015-01-01

    The US radon measurement programme began in the late 1950's 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 <2 % of the radon measurements performed in the 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

    Primary mediastinal sarcomas are aggressive tumors with a very rare incidence. This report describes the case of a 35 year old male patient who presented with acute symptoms of dyspnoea, facial puffiness, engorged neck veins and hoarseness of voice. With the clinical picture consistent with the superior vena caval (SVC) syndrome, the patient was investigated with computed tomography of the chest. This revealed a large soft tissue density mass lesion compressing the SVC along with other critical superior mediastinal structures. Histopathological evaluation of the mass revealed features consistent with a soft tissue sarcoma and positive staining was observed for vimentin and S-100. Cytogenetic analysis by fluorescent in-situ hybridization (FISH) demonstrated the t(X: 18) translocation. Thus diagnosis was established as primary mediastinal synovial sarcoma. Patient was treated with three-cycles of neo-adjuvant (ifosfamide 2400mg/m2 on days 1-5 and doxorubicin 37.5 mg/m2 on days 1 & 2) chemotherapy, to which there was a partial response as per the RECIST criteria. Surgical excision of the mediastinal mass was performed, and further post-operative treatment with adjuvant chemo-radiotherapy was provided. Patient was under regular surveillance at our clinic and remains free of symptoms one-year after treatment completion. But after 14 months of treatment completion patient again had symptoms of progressive dyspnea, hoareness of voice and mild facial puffiness over a period of 2 months. On further investigating he was found to have right-sided centrally located mass with cystic and necrotic changes with extension and compression of trachea, SVC, right upper lobe bronchus and its branches. Histopathological examination of the biopsy from the lesion revealed adenoid cystic carcinoma of the lung. Rest of the metastatic work up was within normal. Immunohistochemistry of the specimen revealed c-Kit positivity. In view of the morbid second surgery he was put on Imatinib 400mg

    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

    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

    Six arsenic species [arsenate, arsenite, arsenocholine, arsenobetaine, monomethyl arsonic acid, and dimethyl arsinic acid] present in human urine were determined using ion-exchange chromatography combined with inductively coupled plasma mass spectrometry (IC-ICP-MS). Baseline separation was achieved for all six species as well as for the internal standard (potassium hexahydroxy antimonate V) in a single chromatographic run of less than 30 min, using an ammonium carbonate buffer gradient (between 10 and 50 mM) at ambient temperature, in conjunction with cation- and anion-exchange columns in series. The performance of the method was evaluated with respect to linearity, precision, accuracy, and detection limits. This method was applied to determine the concentration of these six arsenic species in human urine samples (n = 251) collected from a population-based exposure assessment survey. Method precision was demonstrated by the analysis of duplicate samples that were prepared over a 2-year analysis period. Total arsenic was also determined for the urine samples using flow injection analysis coupled to ICP-MS. The summed concentration of the arsenic species was compared with the measured arsenic total to demonstrate mass balance.

    Endovascular Optical Coherence Tomography (OCT) has previously been used in both bench-top and clinical environments to produce vascular images, and can be helpful in characterizing, among other pathologies, plaque build-up and impedances to normal blood flow. The raw data produced can also be processed to yield high-resolution blood velocity information, but this computation is expensive and has previously only been available a posteriori using post-processing software. Real-time Doppler OCT (DOCT) imaging has been demonstrated before in the skin and eye, but this capability has not been available to vascular surgeons. Graphics Processing Units (GPUs) can be used to dramatically accelerate this type of distributed computation. In this paper we present a software package capable of real-time DOCT processing and circular image display using GPU acceleration designed to operate with catheter-based clinical OCT systems. This image data is overlayed onto structural images providing clinicians with live, high-resolution blood velocity information to complement anatomical data. Further, we validated flow data obtained in real time using a carotid flow phantom - constructed using 3D structural OCT data - and controlled flow from an external pump.

    The 1994 International Conference on Population and Development (ICPD) was orchestrated and largely controlled by such pro-choice groups as the UN Population Fund, Planned Parenthood, and radical American feminists. Efforts to promote abortion in parts of the world where it is illegal were couched in such terms as "safe motherhood" and "reproductive health." These efforts failed, however, with inclusion of the clause stating that abortion shall not be promoted as a means of family planning. However, the seeds of abortion, in the form of unnatural contraception, continue to be spread throughout the world. On the other hand, in the nongovernmental organization forum, which ran concurrently with the ICPD, pro-life organizations attracted a great deal of attention at the International Right to Life Federation booth. A workshop on natural family planning was attended by only a few people, but interest was high and the attendees followed-up by requesting more information during the Forum. A press conference held by Catholics for a Free Choice backfired because the mostly Moslem audience left angry at the women's apparent lack of obedience to the Pope. Other American feminists were confronted with the sight of women from the Third World picketing the conference with signs like "2 cars for every family in the North; one child for every family in the South." The pro-choice activists succeeded in bolstering the esteem of the Pope by making it evident that he is carrying the burden of family values almost singlehandedly.

    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.

    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)

  14. Economic burden of torture for a refugee host country: development of a model and presentation of a country case study

    2014-01-01

    Background Torture is an important social and political problem worldwide that affects millions of people. 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 10,073,419,200 CHF in the loss of productivity if one would consider 30 years of loss per survivor. Conclusion Our study shows that a rough estimation of the costs related to torture is possible with some prerequisites, such as access to social and economic indicators at the country level.

  15. Influence of HIV and HCV on T cell antigen presentation and challenges in the development of vaccines

    Full Text Available Some of the central challenges for developing effective vaccines against HIV and hepatitis C virus (HCV are similar. Both infections are caused by small, highly mutable, rapidly replicating RNA viruses with the ability to establish long-term chronic pathogenic infection in human hosts. HIV has caused 60 million infections globally and HCV 180 million and both viruses may co-existent among certain populations by virtue of common blood-borne, sexual or vertical transmission. Persistence of both pathogens is achieved by evasion of intrinsic, innate and adaptive immune defenses but with some distinct mechanisms reflecting their differences in evolutionary history, replication characteristics, cell tropism and visibility to mucosal versus systemic and hepatic immune responses. A potent and durable antibody and T cell response is a likely requirement of future HIV and HCV vaccines. Perhaps the single biggest difference between the two vaccine design challenges is that in HCV, a natural model of protective immunity can be found in those who resolve acute infection spontaneously. Such spontaneous resolvers exhibit durable and functional CD4+ and CD8+ T cell responses. However frequent re-infection suggests partial or lack of protective immunity against heterologous HCV strains, possibly indicative of the degree of genetic diversity of circulating HCV genotypes and subtypes. There is no natural model of protective immunity in HIV, however studies of elite controllers, or individuals who have durably suppressed levels of plasma HIV RNA without antiretroviral therapy has provided the strongest evidence for CD8+ T cell responses in controlling viremia and limiting reservoir burden in established infection. Here we compare and contrast the specific mechanisms of immune evasion used by HIV and HCV, which subvert adaptive human leucocyte antigen (HLA-restricted T cell immunity in natural infection, and the challenges these pose for designing effective

    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.

    The authors describe 2 cases of triventricular hydrocephalus initially presenting as aqueductal stenosis that subsequently developed tumors of the pineal and tectal region. The first case resembled late-onset idiopathic aqueductal stenosis on serial imaging. Subsequent imaging revealed a new tumor in the pineal region causing mass effect on the midbrain. The second case presented in a more typical pattern of aqueductal stenosis during infancy. On delayed follow-up imaging, an enlarging tectal mass was discovered. In both cases hydrocephalus was successfully treated by cerebrospinal fluid diversion prior to tumor presentation. The differential diagnoses, diagnostic testing, and treatment course for these unusual cases are discussed. The importance of follow-up MRI in cases of idiopathic aqueductal stenosis is emphasized by these exemplar cases.

    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)

Most of the infected individuals presented severe pneumonia, which evolved to respiratory insufficiency within an average of 4 days. Chest X-rays can reveal diffuse multifocal/ interstitial infiltrates or segmental/lobar consolidation with air bronchogram. The pathogenic potential is high, with mortality rates up to 63%, indicating that the pandemic virus might present high pathogenicity and high mortality. Knowledge of the risk of a pandemic and of the measures to be taken in suspect cases constitutes an important step toward controlling a potential pandemic.

  5. Forkhead Box O1 is present in quiescent pituitary cells during development and is increased in the absence of p27 Kip1.

    Full Text Available Congenital pituitary hormone deficiencies have been reported in approximately one in 4,000 live births, however studies reporting mutations in some widely studied transcription factors account for only a fraction of congenital hormone deficiencies in humans. Anterior pituitary hormones are required for development and function of several glands including gonads, adrenals, and thyroid. In order to identify additional factors that contribute to human congenital hormone deficiencies, we are investigating the forkhead transcription factor, FOXO1, which has been implicated in development of several organs including ovary, testis, and brain. We find that FOXO1 is present in the nuclei of non-dividing pituitary cells during embryonic development, consistent with a role in limiting proliferation and/or promoting differentiation. FOXO1 is present in a subset of differentiated cells at e18.5 and in adult with highest level of expression in somatotrope cells. We detected FOXO1 in p27(Kip1-positive cells at e14.5. In the absence of p27(Kip1 the number of pituitary cells containing FOXO1 is significantly increased at e14.5 suggesting that a feedback loop regulates the interplay between FOXO1 and p27(Kip1.

    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.

  7. Present status in research and development of a multi-purpose high-temperature gas cooled reactor in JAERI. 1985 ed.

    International Nuclear Information System (INIS)

    1985-01-01

    In Japan, it is forecast that the energy demand in the industries consuming large amount of energy, such as iron and steel, paper and pulp, chemicals, ceramics and earth and stones, will decrease due to energy saving and the stagnant demand of those products, whereas mechatronics will largely grow. Accordingly, the demand and supply of whole energy will change. The development of high temperature gas-cooled reactors is highly significant for diversifying and stably ensuring energy resources in Japan. Japan Atomic Energy Research Institute has advanced the research and development of multi-purpose high temperature gas-cooled reactors since 1969, and the main accomplishment carried out so far is briefly reported. The important step in this development is the construction of an experimental reactor, and its preparation is in progress. At present, the rationalizing design of the experimental reactor is carried out, and the construction will begin in fiscal year 1989. In this report, concerning multi-purpose high temperature gas-cooled reactors, the outline of the research and development, the design of the experimental reactor, the research on fuel and graphite, metallic materials, reactor technology, high temperature equipment and structure and others are described.

    Atrial fibrillation (AF) is the most common supraventricular arrhythmia following ST elevation myocardial infarction (STEMI). Oxidative stress and inflammation may cause structural and electrical remodeling in the atria making these critical processes in the pathology of AF. In this study, we aimed to evaluate the association between total oxidative status (TOS), total antioxidative capacity (TAC) and high-sensitivity C-reactive protein (hs-CRP) in the development of AF in patients presenting with STEMI. This prospective cohort study consisted of 346 patients with STEMI. Serum TAC and TOS were assessed by Erel's method. Patients were divided into two groups: those with and those without AF. Predictors of AF were determined by multivariate regression analysis. In the present study, 9.5% of patients developed AF. In the patients with AF, plasma TOS and oxidative stress index (OSI) values were significantly higher and plasma TAC levels were significantly lower compared to those without AF (p = .003, p = .002, p atrial diameter (OR =1.28; 95% CI =1.12-1.47; p atrial diameter and hs-CRP.

    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.

    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

    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.

    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.

    2006-11-01

    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.

Neste contexto, o objetivo deste trabalho foi identificar diferenças no ambiente interno de dois galpões de poedeiras, utilizando monitoramento e posterior comparação estatística das variáveis do ambiente. A análise dos dados não evidenciou maior conforto térmico no galpão recoberto com telhas de barro, em razão da ausência de lanternim que dificultou a renovação do ar por "efeito chaminé". A concentração de amônia medida no interior de ambas as instalações ficou dentro do limite de conforto. O índice de temperatura e umidade do galpão recoberto com telhas de cerâmica apresentou valores maiores que do galpão recoberto com telha de cimento amianto, mesmo se verificando temperaturas de superfície menores nas telhas de cerâmica, evidenciando os efeitos positivos do lanternim na instalação. Com base nos resultados desta pesquisa, recomendam-se, para a região de Bastos, SP, que os aviários para galinhas de postura sejam construídos com lanternim e prolongamento do beiral e que sejam recobertos com telhas de cerâmica.Poulty house typology and the materials used (mainly for roofing are the determining factors for an appropriate thermal condition aiming at production. In this context, the main point of this paper was to identify differences in the internal environment of two poultry houses, using monitoring and afterwards using statistics for comparing the environmental variables. The data analyzed did not show evidence of better thermal comfort for the house which was covered with ceramic roofing tile, because this house did not have ridged vents, making the hot air exit from the house difficult by the "chimney effect". The ammonia concentration measured inside both houses was within the comfort limit. The temperature and humidity index

    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.)

    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. En los países occidentales de altos ingresos, dominados por los valores del individualismo utilitario, las necesidades de

    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.

    Full Text Available A sensitive and novel chemically modified multi-walled carbon nanotubes modified pencil graphite electrode (MCPGE has been developed for the electrochemical investigation of aceclofenac (ACF. MCPGE was characterized by scanning electron microscopy (SEM, cyclic voltammetry (CV and electrochemical impedance spectroscopy (EIS. Phosphate buffer solution (PBS of pH 7.0 was used as a suitable electrolytic medium, in which aceclofenac (ACF exhibited a sensitive adsorption controlled oxidation peaks at +0.12, +0.32 and +0.51 V and a reduction peak at −0.26 V (vs Ag/AgCl. The experimental conditions were optimised by means of investigating the dependence of peak current on solution pH, concentration and scan rate etc. The electrochemical parameters such as surface concentration (Γ, electron transfer coefficient (α and the standard rate constant (ks were investigated at MCPGE. The oxidative peak currents were varied linearly with concentration in the range between 1 × 10−6 to 60 × 10−6 M with a detection limit of 2.6 × 10−9 M. The UV–Vis absorption spectrum of ACF gave the λmax at 272–273 nm and is attributed to the presence of ACF. The applicability of the MCPGE was illustrated by the determination of ACF present in pharmaceutical and human urine samples.

  10. Whole bladder photodynamic therapy: critical review of present-day technology and rationale for development of intravesical laser catheter and monitoring system.

    Present-day whole bladder photodynamic therapy (WBPDT) is cumbersome and time consuming because cystoscopic and ultrasonic manipulations are necessary to position the light emitter within the bladder. More important, WBPDT is inherently unsafe and often ineffective since neither uniform photoirradiation nor accurate light dosimetry can be achieved with the techniques employed to photoirradiate the bladder wall. The intravesical laser catheter (IVLC) eliminates the need for cystoscopy and ultrasonography because passage of the treatment fiber into the catheter's central lumen automatically positions its light-diffusing tip within the center of the bladder. Use of the IVLC delivery system also assures accurate photoirradiation of the bladder wall since inflation of the catheter's balloon transforms the asymmetric bladder into a sphere of known diameter. The light sensor incorporated in the balloon wall provides a method to monitor light fluence and measure total light dose. When provided the parameters of bladder volume, laser energy output, and desired light dose, the computerized control system calculates treatment time and automatically adjusts the period of photoirradiation to compensate for variations in laser light production, energy losses during transmission, and for variations in light intensity resulting from the integrating sphere effect of the bladder wall. This delivery system also increases the safety of WBPDT since the monitor automatically discontinues treatment if any unsafe situation, with respect to light fluence, develops during photoirradiation.

    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.

    The ''International Workshop on Reducing Carbon Dioxide Emissions from the Developing World: Assessment of Benefits, Costs and Barriers'' was the second workshop held as part of a project being conducted by the International Energy Studies Group of Lawrence Berkeley Laboratory, in collaboration with experts from leading institutions across the developing world. The goal of the project is to analyze long-range energy consumption in developing countries and its potential contribution to global climate change. The US Environmental Protection Agency (EPA) is supporting this work, the results of which already have made a key contribution to the technical analysis being used as the basis for discussion by the Energy and Industry Sub-group of the Intergovernmental Panel on Climate Change (IPCC). The main purpose of this workshop was two-fold: (1) to discuss the feasibility of implementing the efficiency improvements and fuel switching measures incorporated into the long-term energy scenarios created for 17 developing countries and (2) to examine the costs and benefits of reducing energy-related carbon dioxide emissions generated by developing countries

    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)

    2013-04-01

    The Department of Energy's Geothermal Technologies Office (GTO) provides RD&D funding for geothermal exploration technologies with the goal of lowering the risks and costs of geothermal development and exploration. In 2012, NREL was tasked with developing a metric to measure the impacts of this RD&D funding on the cost and time required for exploration activities. The development of this metric included collecting cost and time data for exploration techniques, creating a baseline suite of exploration techniques to which future exploration and cost and time improvements could be compared, and developing an online tool for graphically showing potential project impacts (all available at http://en.openei.org/wiki/Gateway:Geothermal). The conference paper describes the methodology used to define the baseline exploration suite of techniques (baseline), as well as the approach that was used to create the cost and time data set that populates the baseline. The resulting product, an online tool for measuring impact, and the aggregated cost and time data are available on the Open EI website for public access (http://en.openei.org).

    Background Patient participation in research and in development of interventions has become a hot topic. Research on health beliefs of stakeholders shows that patients do have other views on health and well-being than health professionals without any experience of a chronic condition themselves

    Full Text Available Avian metapneumovirus (AMPV belongs to Metapneumovirus genus of Paramyxoviridae family. Virus isolation, serology, and detection of genomic RNA are used as diagnostic methods for AMPV. The aim of the present study was to compare the detection of six subgroup A AMPV isolates (AMPV/A viral RNA by using different conventional and real time RT-PCR methods. Two new RT-PCR tests and two real time RT-PCR tests, both detecting fusion (F gene and nucleocapsid (N gene were compared with an established test for the attachment (G gene. All the RT-PCR tested assays were able to detect the AMPV/A. The lower detection limits were observed using the N-, F- based RRT-PCR and F-based conventional RT-PCR (10(0.3 to 10¹ TCID50 mL-1. The present study suggests that the conventional F-based RT-PCR presented similar detection limit when compared to N- and F-based RRT-PCR and they can be successfully used for AMPV/A detection.O metapneumovírus aviário (AMPV pertence ao gênero Metapneumovirus, família Paramyxoviridae. Isolamento viral, sorologia e detecção do RNA genômico são atualmente as técnicas utilizadas para o diagnóstico desse agente. O objetivo do presente estudo foi comparar a detecção de RNA viral de seis isolados de AMPV, subtipo A (AMPV/A, utilizando diferentes métodos de RT-PCR convencional e real time RT-PCR (RRT-PCR. Duas novas técnicas de RT-PCR convencional e duas técnicas de RRT-PCR, ambas para a detecção dos genes da nucleoproteína (N e da proteína de fusão (F, foram comparadas com um RT-PCR previamente estabelecido para a detecção do AMPV (gene da glicoproteína -G. Todos esses métodos foram capazes de detectar os isolados AMPV/A. As técnicas RRT-PCR (genes F e N mostraram os menores limites de detecção (10(0.3 to 10¹ TCID50 mL-1. Os resultados sugerem que as técnicas RT-PCR convencional (gene F e as técnicas de RRT-PCR (gene F e N desenvolvidas no presente estudo podem ser utilizadas com sucesso para a detecção do

    2013-01-01

    . The “ATLAS Metadata Interface” framework (AMI) has been developed in the context of ATLAS, one of the largest scientific collaborations. AMI can be considered to be a mature application, since its basic architecture has been maintained for over 10 years. In this paper we describe briefly the architecture and the main uses of the framework within the experiment (TagCollector for release management and Dataset Discovery). These two applications, which share almost 2000 registered users, are superficially quite different, however much of the code is shared and they have been developed and maintained over a decade almost completely by the same team of 3 people. We discuss how the architectural principles established at the beginning of the project have allowed us to continue both to integrate the new technologies and to respond to the new metadata use cases which inevitably appear over such a time period.

    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.

    Metal and ceramic powders are the basis for many technical and industrial processes and applications, such as powder metallurgy, thermal spraying, electronics and catalysis. Nevertheless, there is still a need for further developments, because the powdery raw materials eventually determine the properties of final products and may be the cause of the problems in the processing of these: Impurities or corrosion processes at the powder production (e.g. by the grinding processes) can have a disad...

    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.

    Full Text Available Globally, group B Streptococcus (GBS remains the leading cause of sepsis and meningitis in young infants, with its greatest burden in the first 90 days of life. Intrapartum antibiotic prophylaxis (IAP for women at risk of transmitting GBS to their newborns has been effective in reducing, but not eliminating, the young infant GBS disease burden in many high income countries. However, identification of women at risk and administration of IAP is very difficult in many low and middle income country (LMIC settings, and is not possible for home deliveries. Immunization of pregnant women with a GBS vaccine represents an alternate pathway to protecting newborns from GBS disease, through the transplacental antibody transfer to the fetus in utero. This approach to prevent GBS disease in young infants is currently under development, and is approaching late stage clinical evaluation. This manuscript includes a review of the natural history of the disease, global disease burden estimates, diagnosis and existing control options in different settings, the biological rationale for a vaccine including previous supportive studies, analysis of current candidates in development, possible correlates of protection and current status of immunogenicity assays. Future potential vaccine development pathways to licensure and use in LMICs, trial design and implementation options are discussed, with the objective to provide a basis for reflection, rather than recommendations.

    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

    2012-01-01

    Full Text Available AL amyloidosis complicating monoclonal gammopathy of undetermined significance (MGUS has usually a predominant glomerular deposition of lambda light chain. Heavy proteinuria is one of its cardinal manifestations. A 78-year-old man with a 9-year history of IgG kappa light-chain-MGUS and normal urine protein excretion developed severe renal failure. Serum levels of kappa light chain and serum IgG had been stable while proteinuria was absent throughout the nine-year period. For the first eight years, he had stable stage III chronic kidney disease attributed to bladder outlet obstruction secondary to prostatic malignancy. In the last year, he developed progressive serum creatinine elevation, without any increase in the serum or urine levels of paraproteins or any sign of malignancy. Renal ultrasound and furosemide renogram showed no evidence of urinary obstruction. Renal biopsy revealed AL amyloidosis, with reactivity exclusive for kappa light chains, affecting predominantly the vessels and the interstitium. Glomerular involvement was minimal. Melphalan and prednisone were initiated. However, renal function continues deteriorating. Deposition of AL kappa amyloidosis developing during the course of MGUS predominantly in the wall of the renal vessels and the renal interstitium, while the involvement of the glomeruli is minimal, leads to progressive renal failure and absence of proteinuria. Renal biopsy is required to detect both the presence and the sites of deposition of renal AL kappa light chain amyloidosis.

    (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.

    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.

    The authors made mass anthropometric surveys in 923 first-to-fourth-form pupils and determined the values of 5 variables for height groups 2, 3, and 4, used to justify the functional sizes of furniture for pupils: the length of a shoulder slope above the seat, that of an elbow slope above the seat, that of a popliteal space slope above the floor, the distance from the chair hack to the popliteal space, and the highest pelvic width. Differences were found in the anthropometric values in the present-day junior pupils and the equals in age of the early 1970s. The present-day children are characterized by changes in body proportions (a decrease in height and an increase in the length of the shin and femur), which should be kept in mind on optimizing the working place of pupils. It is suggested that popliteal space length rather than the currently applied height should be used as a fitting ratio of anthropometric characteristics to the functional sizes of furniture for pupils.

  4. Optimal MHC-II-restricted tumor antigen presentation to CD4+ T helper cells: the key issue for development of anti-tumor vaccines

    2012-07-01

    Full Text Available Abstract Present immunoprevention and immunotherapeutic approaches against cancer suffer from the limitation of being not “sterilizing” procedures, as very poor protection against the tumor is obtained. Thus newly conceived anti-tumor vaccination strategies are urgently needed. In this review we will focus on ways to provide optimal MHC class II-restricted tumor antigen presentation to CD4+ T helper cells as a crucial parameter to get optimal and protective adaptive immune response against tumor. Through the description of successful preventive or therapeutic experimental approaches to vaccinate the host against the tumor we will show that optimal activation of MHC class II-restricted tumor specific CD4+ T helper cells can be achieved in various ways. Interestingly, the success in tumor eradication and/or growth arrest generated by classical therapies such as radiotherapy and chemotherapy in some instances can be re-interpreted on the basis of an adaptive immune response induced by providing suitable access of tumor-associated antigens to MHC class II molecules. Therefore, focussing on strategies to generate better and suitable MHC class II–restricted activation of tumor specific CD4+ T helper cells may have an important impact on fighting and defeating cancer.

    Recently, Campylobacter ureolyticus has been detected for the first time in the faeces of patients with acute gastroenteritis using polymerase chain reaction (PCR) techniques. Cultural isolation of C. ureolyticusis is not possible using the established selective methods for the isolation of thermophilic Campylobacter spp. from faeces. The aim of the current study is to develop a new selective medium capable of isolating C. ureolyticus from faecal samples. The newly-developed medium consists of Anaerobe Basal Agar with 10 g/L additional agar, 2 g/L sodium formate and 3 g/L sodium fumarate dibasic, to which 10 mg/L nalidixic acid, 10 mg/L amphotericin B and 20 mg/L vancomycin (NAV) are added as selective agents. Validation studies have shown that this experimental selective medium completely inhibits growth of Candida spp. and of Enterococcus spp. and permits reduced growth of selected coliforms and Proteus spp. Growth of Campylobacter ureolyticus on NAV medium is optimal in anaerobic and enriched hydrogen atmospheres. Additionally, an overnight enrichment step using Bolton broth to which 2 g/L sodium formate, 3 g/L sodium fumarate dibasic and the NAV supplement are added, in place of the commercial Bolton broth supplement, allows improved recovery of C. ureolyticus from patients' faeces.

    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.

    The AAPM, through its members, meetings, and its flagship journal Medical Physics, has played an important role in the development and growth of x-ray tomography in the last 50 years. From a spate of early articles in the 1970s characterizing the first commercial computed tomography (CT) scanners through the “slice wars” of the 1990s and 2000s, the history of CT and related techniques such as tomosynthesis can readily be traced through the pages of Medical Physics and the annals of the AAPM and RSNA/AAPM Annual Meetings. In this article, the authors intend to give a brief review of the role of Medical Physics and the AAPM in CT and tomosynthesis imaging over the last few decades. PMID:18777932

  9. 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

  10. Development and cross-cultural testing of the International Depression Symptom Scale (IDSS): a measurement instrument designed to represent global presentations of depression.

    Self-report measurement instruments are commonly used to screen for mental health disorders in Low and Middle-Income Countries (LMIC). The Western origins of most depression instruments may constitute a bias when used globally. Western measures based on the DSM, do not fully capture the expression of depression globally. We developed a self-report scale design to address this limitation, the International Depression Symptom Scale-General version (IDSS-G), based on empirical evidence of the signs and symptoms of depression reported across cultures. This paper describes the rationale and process of its development and the results of an initial test among a non-Western population. We evaluated internal consistency reliability, test-retest reliability and inter-rater reliability of the IDSS-G in a sample N  = 147 male and female attendees of primary health clinics in Yangon, Myanmar. For criterion validity, IDSS-G scores were compared with diagnosis by local psychiatrists using the Structured Clinical Interview for DSM (SCID). Construct validity was evaluated by investigating associations between the IDSS-G and the Patient Health Questionnaire (PHQ), impaired function, and suicidal ideation. The IDSS-G showed high internal consistency reliability ( α  = 0.92), test-retest reliability ( r  = 0.87), and inter-rater reliability ( ICC  = 0.90). Strong correlations between the IDSS-G and PHQ-9, functioning, and suicidal ideation supported construct validity. Criterion validity was supported for use of the IDSS-G to identify people with a SCID diagnosed depressive disorder (major depression/dysthymia). The IDSS-G also demonstrated incremental validity by predicting functional impairment beyond that predicted by the PHQ-9. Results suggest that the IDSS-G accurately assesses depression in this population. Future testing in other populations will follow.

    Pelvic venous incompetence can cause symptomatic varicose veins in the perineum, buttock, and thigh. Presentation, symptom severity, and response to treatment of pelvic source varicose veins are not well defined. Currently available tools to measure the severity of lower extremity venous disease and its effects on quality of life may be inadequate to assess disease severity in these patients. The purpose of this study was to evaluate the histories, demographics, and clinical presentations of women with pelvic source varicose veins and to compare these data to a population of women with nonpelvic source varicose veins. A total of 72 female patients with symptomatic pelvic source varicose veins were prospectively followed up. Age, weight, height, parity, and birth weights of offspring were recorded. Both pelvic source varicose veins and saphenous incompetence were identified by duplex ultrasound. Patients were queried as to their primary symptoms, activities that made their symptoms worse, and time when their symptoms were most prominent. Severity of disease was objectively evaluated using the revised Venous Clinical Severity Score (rVCSS) and 10-point numeric pain rating scale (NPRS). Compared with women without a pelvic source of varicose veins (N = 1163), patients with pelvic source varicose veins were younger (mean, 44.6 ± 8.6 vs 52.6 ± 12.9 years; P source varicose veins are a unique subset of patients. They are younger and thinner than those with nonpelvic source varicose veins, have larger infants than the general U.S. population, and have an inverse correlation between age and pain. As the majority of premenopausal patients have increased symptoms during menses, this may be due to hormonal influence. As it is poorly associated with patient-reported discomfort, the rVCSS is a poor tool for evaluating pelvic source varicose veins.

    We report the development and characterization of SJ-9A4, a monoclonal antibody (MoAb) produced against common acute lymphoblastic leukemia (C-ALL) cell lines. SJ-9A4 reacted with C-ALL, B-cell chronic lymphocytic leukemia (B-CLL), platelets and C-ALL neuroblastoma (NB) and the K562 cell lines. It had no significant reactivity with erythrocytes, granulocytes, circulating T or B lymphocytes, monocytes, granulocytic cell lines or a Ewing's sarcoma cell line. SJ-9A4 was shown to recognize the same region as two other MoAb to the p24 antigen, BA-2 and DU-ALL-1, as demonstrated by their ability to inhibit the binding of labeled SJ-9A4 to NALM-1 and NB cells. Other MoAb: J5, PI 153/3 and monoclonal anti-HLA-DR antibodies gave no inhibition. A solid phase indirect radioimmunometric assay (IRA) was developed which enabled the detection of P24 from C-ALL cells, utilizing its ability to bind the Ricinus communis agglutinin (RCA1) or wheat germ agglutinin (WGA) and SJ-9A4 simultaneously. When BA-2 and DU-ALL-1 were used in place of SJ-9A4, similar IRA results were obtained. Using the RCA1/SJ-9A4-IRA, P24 from as few as 1.6 X 10(4) cells of a C-ALL cell line could be detected; however, similar extracts of NB cell lines were negative despite high levels of SJ-9A4 binding to intact cells. The presence of P24 in NB extracts was demonstrated by (1) preincubation of NB extracts with SJ-9A4 which blocked MoAb binding to P24 and (2) immunoadsorption of P24 from solubilized membranes of 35S-methionine (met) labeled NB cells. Treatment of NB cells with neuraminidase did not result in IRA binding when either RCA1 or WGA were used as the solid phase lectin indicating that the differences in lectin affinity are not due to over sialation of NB membrane glycoproteins. These findings demonstrate a difference in the glycosylation of P24 from C-ALL and NB cells.

    People with multiple sclerosis (MS) are increasingly using the Internet in the daily management of their condition. They search for high-quality information in plain language, from independent sources, based on reliable and up-to-date evidence. The Integrating and Deriving Evidence, Experiences and Preferences (IN-DEEP) project in Italy and Australia aimed to provide people with MS and family members with an online source of evidence-based information, starting from their information needs. This paper reports on the Italian project's website. Contents, layout and wording were developed with people with MS and pilot-tested. The website was evaluated using an online 29-item questionnaire for ease of language, contents, navigation, and usefulness of information aimed at people with MS, family members and the general population. The website ( http://indeep.istituto-besta.it/) is structured in multiple levels of information. The first topic was interferons-β for people with relapsing-remitting MS. In all, 433 people responded to the survey (276 people with MS, 68 family members and 89 others). The mean age was 45 years, almost 90% had a high school diploma, about 80% had relapsing-remitting MS, and the median disease duration was seven years. About 90% judged the website clear, understandable, useful, and easy to navigate. Ninety percent of people with MS and family members would recommend it to others. Sixty-two percent reported they felt confident in making decisions on interferons-β after reading the website. The model was judged clear and useful. It could be adapted to other topics and diseases. Clinicians may find it useful in their relationship with patients.

  15. Making your presentation fun: creative presentation techniques

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

Avaliou-se o efeito do uso de cama-de-aviário semidecomposta incorporada ao solo e populações de plantas sobre as características morfológicas, a produção e a qualidade do óleo essencial dos capítulos florais da camomila cv. 'Mandirituba'. Os fatores em estudo deram origem aos nove tratamentos, combinando respectivamente espaçamentos entre plantas (m e cama-de-aviário (kg m-2: 0,16 e 1,2; 0,24 e 1,2; 0,16 e 2,8; 0,24 e 2,8; 0,20 e 2,0; 0,11 e 1,2; 0,29 e 2,8; 0,16 e 0,2 e 0,24 e 3,8, dispostos no delineamento experimental de blocos casualizados, com quatro repetições. As características avaliadas foram altura de plantas; número, altura e diâmetro, massa fresca e seca e análise qualitativa do óleo essencial dos capítulos florais. A altura média máxima das plantas da camomila 'Mandirituba' foi de 0,61 m, sendo considerada cultivar de porte baixo. Não houve efeito significativo da interação espaçamentos entre plantas e cama-de-aviário sobre as características avaliadas. A produção dos capítulos florais foi influenciada mais intensamente pelo espaçamento entre plantas do que pela cama-de-aviário. O menor espaçamento induziu os maiores números (56,57 milhões ha-1 e massas secas dos capítulos florais (1.080 kg ha-1.

    poultry litter rates caused a vertical movement of P down the soil columns, as verified by P concentrations extracted by Mehlich-1 and NaHCO3 (Olsen. The environmental critical level (ECL, i.e., the P soil concentration above which P leaching increases exponentially, was 100 and 150 mg dm-3 by Mehlich-1 and 40 and 60 mg dm-3 by Olsen, for the sandy loam and clay soils, respectively. In highly weathered soils, where residual P is accumulated by successive crops, P leaching through the profile can be significant, particularly when poultry litter is applied as fertilizer.A eutroficação de aquíferos está fortemente ligada à mobilidade de P nos solos. Embora essa mobilidade tenha sido considerada, num passado mais distante, como inexpressiva, estudos mais recentes têm mostrado que o P, tanto na forma orgânica (Po quanto na inorgânica (Pi, pode se perder por percolação e eluviação de partículas através do perfil de solos, particularmente naqueles menos intemperizados e, ou, arenosos com menor adsorção de P. O objetivo deste trabalho foi verificar perdas por lixiviação e eluviação de formas de P em colunas de solos, constituídas por cinco anéis de PVC sobrepostos, com 5 cm de diâmetro e 10 cm de altura cada, submetidas a fluxos de percolação de água. Foram utilizadas amostras de dois Latossolos Vermelho-Amarelos, texturas argilosa e média. Os solos receberam, previamente, quatro doses de P na forma de KH2PO4, correspondentes a 0; 12,5; 25 e 50 % da capacidade máxima de adsorção de P (CMAP, homogeneizadas com todo o volume de solo das colunas e deixados em incubação por 60 dias. No anel superior, aplicou-se, homogeneamente, cama de aviário nas doses equivalentes a 0, 20, 40, 80 e 160 t ha-1; com base no peso do material seco. O experimento foi constituído pelo esquema fatorial: quatro níveis da CMAP, cinco doses de cama de aviário, dois solos, com três repetições dispostas em blocos casualizados.

    structure (chemical order, anisotropy, charge transfer, magnetic order) versus an external parameter like temperature, pressure, magnetic or electric field. Modern crystallography is also extended to the study of very small crystals, powders, ill-ordered or non-crystallized materials. Thus presently, crystallography is concerned with any solid that “scatters” an incident beam. Nevertheless, as quoted by A. Guinier, “the problems facing crystallographers have only changed, ... new ones have appeared which require reflection and imagination, ... and which in turn may still bring much joy to all those who like crystallography” [4]. Such developments open up crystallography to modern materials like artificial ones and nanostructures with low- and/or multi-scaled-periodicities and/or extremely small “crystal size” and to materials of the “real world”, with mixtures of phases and/or amorphous contribution and/or defects, a common characteristic of ancient materials analysed in patrimonial research. In our contribution we will show by selected examples that these improvements were allowed (i) by the use of powerful sources, apparatus and detectors which allow micro-diffraction, in-situ diffraction, spectroscopy, resonant scattering, inelastic scattering, coherent scattering, (ii) by the development of methods like diffraction anomalous fine structure (DAFS), pair distribution function (PDF), simulated annealing, single object reconstruction, (iii) by combination of scattering and spectroscopy and by combination of scattering and microscopy. Such combination of different approaches is very efficient and, as said by H. Curien at the IUCr Bordeaux Congress in 1990, “in crystallography, there is a constant alternation between the crystal space and its associated reciprocal space, ... the alternation between experiment and model building is another feature of crystallography activity ..., the crystallographer relies both on his computer and on his diffractometer

    Reducing radiation dose in dual energy computed tomography (DECT) is highly desirable but it may lead to excessive noise in the filtered backprojection (FBP) reconstructed DECT images, which can inevitably increase the diagnostic uncertainty. To obtain clinically acceptable DECT images from low-mAs acquisitions, in this work we develop a novel scheme based on measurement of DECT data. In this scheme, inspired by the success of edge-preserving non-local means (NLM) filtering in CT imaging and the intrinsic characteristics underlying DECT images, i.e. global correlation and non-local similarity, an averaged image induced NLM-based (aviNLM) regularization is incorporated into the penalized weighted least-squares (PWLS) framework. Specifically, the presented NLM-based regularization is designed by averaging the acquired DECT images, which takes the image similarity within the two energies into consideration. In addition, the weighted least-squares term takes into account DECT data-dependent variance. For simplicity, the presented scheme was termed as ‘PWLS-aviNLM’. The performance of the presented PWLS-aviNLM algorithm was validated and evaluated on digital phantom, physical phantom and patient data. The extensive experiments validated that the presented PWLS-aviNLM algorithm outperforms the FBP, PWLS-TV and PWLS-NLM algorithms quantitatively. More importantly, it delivers the best qualitative results with the finest details and the fewest noise-induced artifacts, due to the aviNLM regularization learned from DECT images. This study demonstrated the feasibility and efficacy of the presented PWLS-aviNLM algorithm to improve the DECT reconstruction and resulting material decomposition.

    Full Text Available Five cases of neurospyhilis with atypical manifestation have been reported. Of these four cases presented as acute neurological illness and showed variable recovery after antisyp′iiilitic therapy. One of these cases had parinaud sip which was unaffected by treatment One case presented as dementia and gave poor response to therapy. In only one of these five cases was reagin in CSF demonstrated. Lange′s colloidal gold test was negative in all. As such failure to demonstrate reagin in CSF does not rule out the diagnosis of neurosyphilis. In an antibiotic era patients may inadvertently receive some antibiotics prior to presentation to a clinician and therefore are unlikely to present with typical neurological and laboratory findings.

    Neurofibromatosis (NF) is considered to be a heterogeneous neuroectodermal disease clinically defined by the presence of neurofibromas, multiple café-au-lait spots, intertriginous freckles and Lisch nodules. Mosaicism explains atypical presentations of the disease. Early mutations, before tissue differentiation, give rise to generalized disease. We report an atypical presentation of neurofibromatosis with an unusual distribution of neurofibromas, a peculiar, clinically and pathologically, neurofibroma on the trunk and the association with an ovarian serous cystoadenofibroma.

    Full Text Available Com o incremento exponencial da avicultura no Brasil, a disponibilidade de dejetos de aves e de cama de aviário tem aumentado de maneira semelhante. A proibição de uso desses produtos na ração animal tem feito com que eles sejam direcionados para a produção agrícola como fertilizantes. Ainda há na literatura carência de informação sobre lixiviação de bases no perfil do solo em conseqüência do efeito de ânions inorgânicos acompanhantes, como cloreto, nitrato e sulfato, e do efeito complexante de ácidos orgânicos de baixa massa molecular. O objetivo deste trabalho foi estudar o efeito da aplicação de cama de aviário na lixiviação de Ca, Mg, K e Na em solos e sua associação com ânions inorgânicos e ácidos orgânicos de baixa molecular. Amostras de dois Latossolos Vermelho-Amarelos, um de textura média e outro de textura argilosa, foram colocadas em colunas de PVC constituídas de cinco anéis, cada um com 10 cm de altura e 5 cm de diâmetro, ligados entre si com fita adesiva. O solo colocado no anel superior recebeu, homogeneamente, cinco tipos de camas de aviário: casca de café, casca de arroz, sabugo de milho, capim-napier e maravalha, totalizando 160 t ha-1 de material seco, comparado à testemunha (sem a cama de aviário. O experimento constituiu um fatorial 5 x 2, com cinco camas e dois solos, dispostos em blocos casualizados com três repetições. As colunas foram submetidas a 10 percolações com água deionizada, duas vezes por semana, até atingirem o volume de 1.200 mm de chuvas. Nos 10 percolados, foram analisadas as concentrações de Ca, Mg, K e Na, dos ânions Cl-, NO3-e SO4(2- e de ácidos orgânicos de baixa massa molecular. Houve grande lixiviação de bases nas colunas, principalmente até a terceira percolação. Esse fato foi causado pela adição dessas bases, em doses elevadas, pelas camas de aviário e, aparentemente, também pelo efeito dos ânions acompanhantes Cl-, NO3-e SO4(2-no solo de

    Sheehan's syndrome (SS) refers to the occurrence of varying degree of hypopituitarism after parturition (1). It is a rare cause of hypopituitarism in developed countries owing to advances in obstetric care and its frequency is decreasing worldwide. However, it is still frequent in underdeveloped and developing countries. Sheehan's syndrome is often diagnosed late as it evolves slowly (2,3). Reports of psychoses in patients with Sheehan's syndrome are rare. Herein, a case report of psychosis in a 31 year old woman who developed Sheehan's syndrome preceded by postpartum haemorrhage is presented. Treatment with thyroxine and glucocorticoids resulted in complete remission after attaining euthyroid and eucortisolemic state. PMID:23483784

    Data are usually collected in a raw format and thus the inherent information is difficult to understand. Therefore, raw data need to be summarized, processed, and analyzed. However, no matter how well manipulated, the information derived from the raw data should be presented in an effective format, otherwise, it would be a great loss for both authors and readers. In this article, the techniques of data and information presentation in textual, tabular, and graphical forms are introduced. Text is the principal method for explaining findings, outlining trends, and providing contextual information. A table is best suited for representing individual information and represents both quantitative and qualitative information. A graph is a very effective visual tool as it displays data at a glance, facilitates comparison, and can reveal trends and relationships within the data such as changes over time, frequency distribution, and correlation or relative share of a whole. Text, tables, and graphs for data and information presentation are very powerful communication tools. They can make an article easy to understand, attract and sustain the interest of readers, and efficiently present large amounts of complex information. Moreover, as journal editors and reviewers glance at these presentations before reading the whole article, their importance cannot be ignored.

    Although milk/dairy consumption is part of many cultures and is recommended in most dietary guidelines around the world, its contribution to overall diet quality remains a matter of controversy, leading to a highly polarized debate within the scientific community, media and public sector. The present article, at first, describes the evolutionary roots of milk consumption, then reviews the milk-derived bioactive peptides as health-promoting components. The third part of the article, in general, presents the associations between milk nutrients, disease prevention, and health promotion.

    This report discusses the structural analysis of the Next Generation Space Telescope Mirror System Demonstrator (NMSD) developed by Composite Optics Incorporated (COI) in support of the Next Generation Space Telescope (NGST) project. The mirror was submitted to Marshall Space Flight Center (MSFC) for cryogenic testing and evaluation. Once at MSFC, the mirror was lowered to approximately 40 K and the optical surface distortions were measured. Alongside this experiment, an analytical model was developed and used to compare to the test results. A NASTRAN finite element model was provided by COI and a thermal model was developed from it. Using the thermal model, steady state nodal temperatures were calculated based on the predicted environment of the large cryogenic test chamber at MSFC. This temperature distribution was applied in the structural analysis to solve for the deflections of the optical surface. Finally, these deflections were submitted for optical analysis and comparison to the interferometer test data.
