    Dolbneva Deniza V.

    2017-11-01

    Full Text Available The article is aimed at studying the current status and determining the main results of conducting the State financial audit by the State audit service in Ukraine, as well as developing proposals as to ways of its improvement in view of the experience of the world’s leading countries and the requirements of international standards in this sphere of relations. The main indicators and results, which characterize the status of conducting by bodies of the State Audit Service of the State financial audit on key directions, were considered. The obtained data indicate that the State financial audit is taking place in the direction corresponding to international practice. Today, however, because of a number of problems and declarative provisions related to the organization and conduct of the State financial audit, it cannot fully implement all its functional capabilities and tasks. Directions of improvement and transformation of the State financial audit have been proposed. The prospect for further research is development of a holistic mechanism for the functioning of the State financial audit, which will unite all its directions at different levels and its participants.

    Full Text Available For investors and other users of financial information to be able to act with full transparency and reliability it is necessary, among other things, that it be prepared according to a regulatory framework that is based on international standards that in turn adapt to new requirements of the global economy. The high level of globalization of the world economy has led the International Financial Reporting Standards (IFRS to become the highest international standards applicable throughout the world and in the case of Peru, these standards have been made mandatory in preparing the financial statements of companies incorporated under the scope of the General Corporate law. Thus, the main purpose of this research , having an exploratory design, is ro have an initial approach on the compliance with the, implementation of IFRS in the preparation and presentation of financial statements of Peruvian companies that are not under the supervision of the National Supervisory Commission for Companies and Securities (CONASEV. To this end, first ít presents a general review of the theoretical framework of financial reporting and secondly, an analysis of the Peruvian Setting Accounting Standards related to the preparation and presentation of financial statements. The third part of this work presents and describes the methodological aspects used in the development of this research, for which it has developed a survey that includes eighteen closed questions and two open ended questions, structured according to our main and specific objectives of this research. The survey was distributed to a sample of companies selected from the universe defined in the research. The results are set out in the fourth section of the article, entitled, research results and which analyzes the responses to each of the survey questions. Finally, we present the conclusions and recommendations that can be reached, highlighting among the main ones, a high incidence of tax and legal aspects

    International Nuclear Information System (INIS)

    Baltadjiev, D.; Charakchiev

    2000-01-01

    Tele-radiology is a term becoming increasingly popular in the medical literature. Nevertheless, terminological definitions in this particular field are still rather vague. The scope of applications extend from simple image presenting via analogue telephone lines to transmission of 3-D medical images through a satellite. It is a matter of standards highly differing in terms of data transmission rates, safety, technical demands on the systems and the like. In this article new information technologies, technical aspects, as well as some major applications of tele-radiology are discussed. The current status of tele-medicine/tele-radiology in this country is likewise briefly outlined

    2017-01-01

    The COHERENT Collaboration is realizing a long term neutrino physics research program. The main goals of the program are to detect and study elastic neutrino-nucleus scattering (CEνNS). This process is predicted by Standard Model but it has never been observed experimentally because of the very low energy of the recoil nucleus. COHERENT is using different detector technologies: CsI[Na] and NaI scintillator crystals, a single-phase liquid Ar and a Ge detectors. The placement of all the detector setups is in the basement of the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The current status of the COHERENT experimental program is presented. (paper)

  7. Current status of nuclear power

    International Nuclear Information System (INIS)

    Behnke, W.B.

    1984-01-01

    The decision to devote the 1984 conference to nuclear power is timely and appropriate. Illinois has a long, and distinguished history in the development of civilian nuclear power. The concept was born at the University of Chicago, developed at Argonne National Laboratory and demonstrated on the Commonwealth Edison system at our pioneer Dresden Nuclear Station. Today, Illinois ranks number one in the nation in nuclear generation. With over a quarter century of commercial operating experience, nuclear power has proven its worth and become a significant and growing component of electric power supply domestically and throughout the world. Despite its initial acceptance, however, the nuclear power industry in the U.S. is now in the midst of a difficult period of readjustment stemming largely from the economic and regulatory problems of the past decade. As a result, the costs of plants under construction have increased dramatically, causing serious financial difficulties for several projects and their owners. At the same time, the U.S. is facing hard choices concerning its future energy supplies. Conferences such as this have an important role in clarifying the issues and helping to find solutions to today's pressing energy problems. This paper summarizes the status of nuclear power both here and abroad, discussing the implications of current events in the context of national energy policy and economic development here in Illinois

  8. Biosimilar drugs: Current status.

    Science.gov (United States)

    Kumar, Rajiv; Singh, Jagjit

    2014-07-01

    Biologic products are being developed over the past three decades. The expiry of patent protection for many biological medicines has led to the development of biosimilars in UK or follow on biologics in USA. This article reviews the literature on biosimilar drugs that covers the therapeutic status and regulatory guidelines. Appraisal of published articles from peer reviewed journals for English language publications, search from PubMed, and guidelines from European Medicines Agency, US Food Drug Administration (FDA) and India were used to identify data for review. Literature suggest that biosimilars are similar biological products, i.e., comparable but not identical to the reference product, are not generic version of innovator product and do not ensure therapeutic equivalence. Biosimilars present more challenges than conventional generics and marketing approval is also more complicated. To improve access, US Congress passed the Biologics Price Competition and Innovation act 2009 and US FDA allowed "abbreviated pathway" for their approval. U.S law has defined new standards and terms and EMA scientific guidelines have also set detailed approval standards. India being one of the most preferred manufacturing destinations of biosimilars, there is a need for stringent safety and regulatory guidelines. The New India Guidelines "Draft Guidelines on Similar Biologics were announced in June 2012, by Department of Biotechnology at Boston bio and available online.

  9. Engineered barriers: current status

    International Nuclear Information System (INIS)

    Atkinson, A.; Marsh, G.P.

    1988-01-01

    This report summarises the current state of research relevant to assessing the performance of engineered barriers made of steel and concrete in radioactive waste repositories. The objective of these barriers is to contain the radionuclides within them by providing both physical and chemical impediment to their release. The physical barriers are of most value for highly soluble isotopes with relatively short half-lives (eg 137 Cs), since they can provide containment until a large fraction of the activity has decayed. In addition they can facilitate retrievability for some period after disposal. The chemical barriers operate by beneficial conditioning of the near field groundwater and providing sites for sorption of radionuclides. Both of these reduce the aqueous concentration of radionuclides in the near field. (author)

    Feng, Jonathan

    2011-01-01

    The WIMP paradigm is the glue that joins together much of the high energy and cosmic frontiers. It postulates that most of the matter in the Universe is made of weakly-interacting massive particles, with implications for a broad range of experiments and observations. I will review the WIMP paradigm's underlying motivations, its current status in view of rapid experimental progress on several fronts, and recent theoretical variations on the WIMP paradigm theme.

    2010-01-01

    Cervical cancer is the second largest cause of cancer deaths in women worldwide, with ~500,000 diagnoses and 274,000 deaths annually. It remains a significant source of morbidity and mortality despite effective screening tools and treatments for its precursor high-grade cervical intraepithelial neoplasia (CIN). Increased understanding of cervical pathogenesis has led to the identification of human papillomavirus (HPV) as the etiological agent for cervical cancer and the development of preventive and therapeutic vaccines targeting HPV antigens for the control of cervical cancer. Herein, we discuss the current status of HPV vaccines. PMID:20677402

  19. Dark Matter Detection: Current Status

    International Nuclear Information System (INIS)

    Akerib, Daniel S.

    2011-01-01

    Overwhelming observational evidence indicates that most of the matter in the Universe consists of non-baryonic dark matter. One possibility is that the dark matter is Weakly-Interacting Massive Particles (WIMPs) that were produced in the early Universe. These relics could comprise the Milky Way's dark halo and provide evidence for new particle physics, such as Supersymmetry. This talk focuses on the status of current efforts to detect dark matter by testing the hypothesis that WIMPs exist in the galactic halo. WIMP searches have begun to explore the region of parameter space where SUSY particles could provide dark matter candidates.

    1997-10-01

    The Chief Financial Officers Act of 1990 (CFO Act) establishes the legal framework for improved Federal financial management. The Act requires the agency CFO to prepare, and annually revise, a plan to implement the Office of Management and Budget (OMB) Federal Financial Management Status Report and Five-Year Plan. This is the sixth Status Report and Five-Year Plan submission to OMB by the Department of Energy (DOE). Financial management at the Department operates in an environment of Government-wide efforts to improve financial management and implements legislation and administrative provisions which stress the need for change. This report sets forth the Department`s plans for financial management improvements in the coming years. It also highlights several new initiatives completed or currently underway that will significantly improve the overall effectiveness of financial management at the Department of Energy.

  2. Current status of diuretic renography

    International Nuclear Information System (INIS)

    O'Reilly, P.H.

    1987-01-01

    Percutaneous antegrade perfusion studies constitute a valuable contribution to the investigation of obstructive uropathy. In 1978, the first report of application of diuretic renogram techniques to this problem appeared in the literature. This was the first systematic report of a standardized protocol to be applied to a specific surgical problem. The purpose of the procedure, as with perfusion pressure-flow studies, is to help distinguish between a dilated urinary tract that is obstructed and requires surgery and a nonobstructed system in which urographic dilation and stasis mimic obstruction, but no genuine impedance to urine flow exists, and surgery is not required. The technique provides dual information. It gives quantitative data on individual renal function that perfusion pressure-flow studies do not, and it gives time-activity curves reflecting the urodynamics through the individual upper urinary tracts at normal and high urinary flow rates. In the early days, this information was obtained from probe studies, but the procedure is now almost exclusively performed using the gamma camera, images from which give additional information on the site of any suspected obstruction. In some ways, the development of diuretic renography and that of perfusion pressure-flow studies have proceeded in a competitive fashion, both attempting to answer the same questions by different means. In practice, however, the two tests would be regarded as complementary, as will be shown later in this chapter. The following sections describe the technique of diuretic renography, its current clinical application and status in surgical and nuclear medicine practice, and its role in comparison with other available tests for management of the dilated upper urinary tract

  3. The current international financial crisis: how much is new?

    The paper surveys a broad array of data to compare the scope and impact of three emerging-market financial crises: the debt crisis of the 1980s, the Mexican financial crisis of 1994-95, and the current international financial crisis. While certain conventional views regarding the three episodes are supported by the data examined in this paper, we find that in several respects, the current crisis is more similar to prior emerging-market crisis episodes than is commonly believed.

    Science.gov (United States)

    Crawford, W H

    1986-05-01

    Total expenditures and revenues of 58 US dental school were derived from reports of the ADA Division of Educational Measurements. These financial data were studied by type of dental school (public, state-related private, and private) and by expenditure/revenue categories. Dental schools showed little diversity in expenditures: most were directed toward instruction; few were directed toward research or continuing education. Several distinctive patterns among the three types of dental schools in revenues were observed. Two configurations emerged: public and state-related private dental schools receive more than 75% of their revenues from government and tuition, and private dental schools, more than 50%.

    Churchill, R Sean

    2014-09-01

    Since the original Neer humeral replacement in the 1950s, the standard primary anatomic total shoulder arthroplasty design has slowly evolved. Most recently, the humeral stem has become progressively shorter to help combat stem-related complications. Currently, there are several companies who have developed and marketed a stemless humeral arthroplasty component. Manufacturers' data for 5 stemless shoulder arthroplasty components currently on the market were analyzed and reviewed. A literature review of short-term results for stemless shoulder arthroplasty was completed. Of the stemless shoulder arthroplasty systems available on the market, 3 are currently undergoing clinical trials in the United States. The Tornier Simpliciti (Tornier, Edina, MN, USA) clinical trial began in 2011. The study with 2-year minimum follow-up results is scheduled for completion in November 2014. The Arthrex Eclipse (Arthrex, Naples, FL, USA) clinical trial was started in January 2013. The tentative study completion date is 2017. The Biomet Nano (Biomet, Warsaw, IN, USA) clinical trial began in October 2013 and also has a tentative completion date of 2017. No other clinical trial is currently under way in the United States. Early results for stemless shoulder arthroplasty indicate clinical results similar to standard stemmed shoulder arthroplasty. Radiographic analysis indicates implant stability without migration or subsidence at 2- to 3-year minimum follow-up.. Several stemless shoulder arthroplasty implants are available outside the United States. Early clinical and radiographic results are promising, but well-designed clinical studies and midterm results are lacking. Three clinical trials are currently under way in the United States with initial availability for use anticipated in 2015. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees.

    2015-11-01

    Rotaviruses remain the major cause of childhood diarrheal disease worldwide and of diarrheal deaths of infants and children in developing countries. The huge burden of childhood rotavirus-related diarrhea in the world continues to drive the remarkable pace of vaccine development. Research articles were searched using terms "rotavirus" and "rotavirus vaccine" in MEDLINE and PubMed. Articles not published in the English language, articles without abstracts, and opinion articles were excluded from the review. After preliminary screening, all articles were reviewed and synthesized to provide an overview of current vaccines and vaccination programs. In this review of the global rotavirus vaccines and vaccination programs, the principles of rotavirus vaccine development and the efficacy of the currently licensed vaccines from both developed and developing countries were summarized. Rotavirus is a common cause of diarrhea in children in both developed and developing countries. Rotavirus vaccination is a cost-effective measure to prevent rotavirus diarrhea.

  9. Current Status of RENO Experiment

    International Nuclear Information System (INIS)

    Kim, Soo-Bong

    2010-01-01

    The RENO (Reactor Experiment for Neutrino Oscillation) is under construction to measure the value of the smallest and unknown neutrino mixing angle θ 13 . The experiment will compare the measured fluxes of electron antineutrinos at two detectors located at 290 m and 1.4 km distances from the center of the Yonggwang nuclear reactors in Korea, with world-second largest thermal power output of 16.4 GW. Construction of experimental halls and access tunnels for both near and far detector sites was completed in early 2009. The detectors are near completion, and data-taking is planned to start in mid 2010. An expected number of observed antineutrino is roughly 510 and 80 per day in the near detector and far detector, respectively. An estimated systematic uncertainty associated with the measurement is less than 0.6%, and an expected statistical error is about 0.3%. With three years of data, the experiment will search for the mixing angle values of sin 2 (2θ 13 ) down to 0.02 in 90% C.L. limit. In this talk, the construction status will be presented. (author)

  11. The current status of radiosurgery

    International Nuclear Information System (INIS)

    Mehta, Minesh P.

    1996-01-01

    Objectives: Review the role of radiosurgery in recurrent malignant gliomas for palliative purposes. Review the role of radiosurgery in newly diagnosed malignant glioma as boost therapy and emphasize the randomized clinical trials underway. Review the role of radiosurgery in the management of patients with brain metastases and emphasize the major prognostic factors. Review the recently initiated clinical trials for brain metastases using radiosurgery. Review the role of radiosurgery in the management of benign tumors with specific emphasis on meningioma and acoustic neuroma. Emphasize the rationale for fractionation and present the preliminary results of fractionated stereotactic radiation. Stereotactic localization techniques, originally designed for neurosurgery, have been used to delivery high single doses of radiation to small intracranial targets for more than 25 years, a technique referred to as stereotactic radiosurgery. Radiosurgery has proven to be an attractive alternative to surgery in the management of several benign tumors, such as vestibular schwannomas with better preservation of hearing and facial nerve function than microsurgical resection. For other benign tumors such as meningioma and pituitary adenoma, preliminary results are promising, but longer range studies to confirm high tumor control rates are necessary. For patients with malignant glioma, radiosurgery has been used to escalate the radiation dose to enhance tumor control following surgery and radiation therapy. The rationale for this is grounded in the recent confirmatory randomized prospective trial verifying the value of brachytherapy in this disease. The results of radiosurgery from single institutional experiences for primary and recurrent malignant glioma indicate a palliative benefit as well as a potential survival benefit in a select sub-group of patients based on the appropriate mix of prognostic criteria such as patient age, performance status, tumor size and extent of resection

  12. Engineered barriers: current status 1989

    International Nuclear Information System (INIS)

    Atkinson, A.; Marsh, G.B.

    1989-06-01

    This report summarises the current state of research relevant to assessing the performance of engineered barriers made of steel and concrete in radioactive waste repositories. The objective of these barriers is to contain substantially the radionuclides within them by providing both physical and chemical impediment to their release. The physical barriers are of most value for highly soluble isotopes with relatively short half-lives (eg 137 Cs), since they can provide a measure of containment until a large fraction of the activity has decayed. In addition they can facilitate retrievability for some period after disposal. The chemical barriers operate by beneficial conditioning of the near field groundwater and providing sites for sorption of radionuclides. Both of these reduce the aqueous concentration of radionuclides in the near field. (author)

    2000-01-01

    Since first described in the early 1990s, coronary magnetic resonance angiography (MRA) has evolved as a promising noninvasive modality for imaging of the coronary arteries and evaluation of coronary artery disease. Despite technical limitations, coronary MRA has established value for imaging of anomalous coronary arteries and assessment of bypass graft patency. Current research focuses on the development of optimal respiratory compensation strategies, improved spatial and temporal resolution and faster acquisition of image data. The accurate detection of stenoses and assessment of the severity of coronary atherosclerosis is presently being evaluated with large multi-center studies. With further technique enhancements and more clinical experience, coronary MRA is likely to become the dominant noninvasive modality in clinical cardiology. (orig.) [de

    2015-01-01

    New challenges for regulators are emerging about a specific assessment and appropriate management of the potential risks of nanomaterials. In the framework of European legislation on chemicals, Regulation (EC) No. 1907/2006 REACH aims to ensure the safety of human health and the environment through the collection of information on the physico-chemical characteristics of the substances and on their profile (eco) toxicological and the identification of appropriate risk management linked to 'exposure to these substances without impeding scientific progress and the competitiveness of industry. In order to cover the current shortage of information on the safety of nanomaterials and tackle the acknowledged legal vacuum, are being a rich activities, carried out both by regulators both by stake holders, and discussions on the proposals for adapting the European regulatory framework for chemicals . The European Commission is geared to strengthen the REACH Regulation by means of updates of its annexes. The importance of responding to the regulatory requirements has highlighted the need for cooperation between European organizations, scientists and industries to promote and ensure the safe use of nanomaterials.

  15. The status of neutral currents

    International Nuclear Information System (INIS)

    Zwirner, F.

    1987-11-01

    The situation of particle physics today is quite puzzling. On the one hand, the Standard Model (SM) of strong and electroweak interactions is consistent with all confirmed experimental data but theoretically rather unsatisfactory. On the other hand, none of the many theoretical speculations which try to go beyond the SM has (yet) received the slightest experimental support. The solution to this dilemma can only come from new data: either from the detection of a new particle threshold at high energy colliders, or from the appearance of some small discrepancy in high-precision experiments. A crucial sector for testing the SM and its extensions is that of neutral currents (NC), where an impressive amount of data has been collected in recent years. While waiting for the next generation of experiments, it is certainly useful to take stock of our knowledge, determining the NC parameters as precisely as we can and putting limits on possible deviations from the SM. The present talk contains the results of a recent analysis along these lines: the first part illustrates how a set of 'model-independent' parameters can be extracted from the available NC data, the second part particularizes the analysis to the SM and to some superstring-inspired models with an additional Z' in their low-energy spectrum. 27 refs., 3 figs., 1 tab

  19. Current status of rotational atherectomy.

    Tomey, Matthew I; Kini, Annapoorna S; Sharma, Samin K

    2014-04-01

    Rotational atherectomy facilitates percutaneous coronary intervention for complex de novo lesions with severe calcification. A strategy of routine rotational atherectomy has not, however, conferred reduction in restenosis or major adverse cardiac events. As it is technically demanding, rotational atherectomy is also uncommon. At this 25-year anniversary since the introduction of rotational atherectomy, we sought to review the current state-of-the-art in rotational atherectomy technique, safety, and efficacy data in the modern era of drug-eluting stents, strategies to prevent and manage complications, including slow-flow/no-reflow and burr entrapment, and appropriate use in the context of the broader evolution in the management of stable ischemic heart disease. Fundamental elements of optimal technique include use of a single burr with burr-to-artery ratio of 0.5 to 0.6-rotational speed of 140,000 to 150,000 rpm, gradual burr advancement using a pecking motion, short ablation runs of 15 to 20 s, and avoidance of decelerations >5,000 rpm. Combined with meticulous technique, optimal antiplatelet therapy, vasodilators, flush solution, and provisional use of atropine, temporary pacing, vasopressors, and mechanical support may prevent slow-flow/no-reflow, which in contemporary series is reported in 0.0% to 2.6% of cases. On the basis of the results of recent large clinical trials, a subset of patients with complex coronary artery disease previously assigned to rotational atherectomy may be directed instead to medical therapy alone or bypass surgery. For patients with de novo severely calcified lesions for which rotational atherectomy remains appropriate, referral centers of excellence are required.

    Science.gov (United States)

    Merticariu, George; Toader, Alexandru

    2015-04-01

    rasdaman (Raster Data Manager) is a Free Open Source Array Database Management System which provides functionality for storing and processing massive amounts of raster data in the form of multidimensional arrays. The user can access, process and delete the data using SQL. The key features of rasdaman are: flexibility (datasets of any dimensionality can be processed with the help of SQL queries), scalability (rasdaman's distributed architecture enables it to seamlessly run on cloud infrastructures while offering an increase in performance with the increase of computation resources), performance (real-time access, processing, mixing and filtering of arrays of any dimensionality) and reliability (legacy communication protocol replaced with a new one based on cutting edge technology - Google Protocol Buffers and ZeroMQ). Among the data with which the system works, we can count 1D time series, 2D remote sensing imagery, 3D image time series, 3D geophysical data, and 4D atmospheric and climate data. Most of these representations cannot be stored only in the form of raw arrays, as the location information of the contents is also important for having a correct geoposition on Earth. This is defined by ISO 19123 as coverage data. rasdaman provides coverage data support through the Petascope service. Extensions were added on top of rasdaman in order to provide support for the Geoscience community. The following OGC standards are currently supported: Web Map Service (WMS), Web Coverage Service (WCS), and Web Coverage Processing Service (WCPS). The Web Map Service is an extension which provides zoom and pan navigation over images provided by a map server. Starting with version 9.1, rasdaman supports WMS version 1.3. The Web Coverage Service provides capabilities for downloading multi-dimensional coverage data. Support is also provided for several extensions of this service: Subsetting Extension, Scaling Extension, and, starting with version 9.1, Transaction Extension, which

    Cloutier, J; Ambady, N; Meagher, T; Gabrieli, J D E

    2012-07-01

    The current study examines the effect of status information on the neural substrates of person perception. In an event-related fMRI experiment, participants were presented with photographs of faces preceded with information denoting either: low or high financial status (e.g., "earns $25,000" or "earns $350,000"), or low or high moral status (e.g., "is a tobacco executive" or "does cancer research"). Participants were asked to form an impression of the targets, but were not instructed to explicitly evaluate their social status. Building on previous brain-imaging investigations, regions of interest analyses were performed for brain regions expected to support either cognitive (i.e., intraparietal sulcus) or emotional (i.e., ventromedial prefrontal cortex) components of social status perception. Activation of the intraparietal sulcus was found to be sensitive to the financial status of individuals while activation of the ventromedial prefrontal cortex was sensitive to the moral status of individuals. The implications of these results towards uncovering the neural substrates of status perception and, more broadly, the extended network of brain regions involved in person perception are discussed.

    This article examines the history, current status, and future direction of community-based dental education (CBDE). The key issues addressed include the reasons that dentistry developed a different clinical education model than the other health professions; how government programs, private medical foundations, and early adopter schools influenced the development of CBDE; the societal and financial factors that are leading more schools to increase the time that senior dental students spend in community programs; the impact of CBDE on school finances and faculty and student perceptions; and the reasons that CBDE is likely to become a core part of the clinical education of all dental graduates.

  11. SOME CONSIDERATIONS ON LOCAL FINANCIAL AUTONOMY IN THE CONTEXT OF THE CURRENT FINANCIAL CRISIS

    2012-03-01

    Full Text Available Financing of local authorities is currently at the Centre of the political discourse is a daily concern. Romania faces, usually with an attempt to offset the need for control and reduction of public spending with greater financial autonomy of local authorities. At the time, it was searched and searches for a path, a means to achieve a fair distribution of financial resources between the various levels of administration, budget reductions to all of them. If strengthening democracy means to strengthen local autonomy, then it means you have created a system for financing local authorities to be efficient, fair and pointing towards the economic needs of States. In other words, decentralization and local financing and the principle of subsidiarity are mutually dependent. Rightly, the decentralisation of financial management is considered to be the "backbone" of the administrative system of decentralisation, the financial resources being those which are operational link between the needs of local communities and the rules necessary to satisfy them. Thus, the lack of financial resources of the local self-government can result in failure to meet the needs of its members, which at the same time failure of administrative decentralization. The decentralisation of financial management can also be seen as the Government of some specific functions on the line of management authority and the tax revenue to the local public authorities.

    Full Text Available The article presents the results of studying the processes of reforming the financial and institutional space of the eurozone, which in the long run creates the foundation for basic changes, which will result in not just a postcrisis “restart” of the system of financial institutions, but the creation of new mechanisms of liquidity circulation and in view of this the restructuring of the current model of investment process from mainly the banking into the market (stock one. On the basis of the analysis of the credit cooperation between banking institutions of the eurozone and the real sector there made conclusions about the limited effectiveness of the current model of investment support due to the inability of the dominant financial institutions (banks to enable economic recovery under conditions of the gap between the complementary interaction of banking institutions and the real sector of the economy. The paper justifies that the gap between the complementarity of the banking system and the real sector emerged also in connection with the formation of the negative in the general economic context complementarity of the state and the banking sector, which greatly distorts the competitive foundations of the European financial and institutional space, contributes to the banking lobby, hinders the process of reforming the banking space, which will be of limited effectiveness in the future

    Goldstein, Jennifer N; Zhang, Zugui; Schwartz, J Sanford; Hicks, LeRoi S

    2018-01-01

    Medicare beneficiaries hospitalized under observation status are subject to cost-sharing with no spending limit under Medicare Part B. Because low-income status is associated with increased hospital use, there is concern that such beneficiaries may be at increased risk for high use and out-of-pocket costs related to observation care. Our objective was to determine whether low-income Medicare beneficiaries are at risk for high use and high financial liability for observation care compared with higher-income beneficiaries. We performed a retrospective, observational analysis of Medicare Part B claims and US Census Bureau data from 2013. Medicare beneficiaries with Part A and B coverage for the full calendar year, with 1 or more observation stay(s), were included in the study. Beneficiaries were divided into quartiles representing poverty level. The associations between poverty quartile and high use of observation care and between poverty quartile and high financial liability for observation care were evaluated. After multivariate adjustment, the risk of high use was higher for beneficiaries in the poor (Quartile 3) and poorest (Quartile 4) quartiles compared with those in the wealthiest quartile (Quartile 1) (adjusted odds ratio [AOR], 1.21; 95% confidence interval [CI], 1.13-1.31; AOR, 1.24; 95% CI, 1.16-1.33). The risk of high financial liability was higher in every poverty quartile compared with the wealthiest and peaked in Quartile 3, which represented the poor but not the poorest beneficiaries (AOR, 1.17; 95% CI, 1.10-1.24). Poverty predicts high use of observation care. The poor or near poor may be at highest risk for high liability. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available In the current economic conditions, accounting applications seem to face new and complex challenges. Especially, these challenges are on the basis of fair value. Recent crisis has highlighted the complexity and difficulty of valuing financial instruments when market information is not available or not sufficient to give better economic decisions. FASB 157 “Fair Value Accounting” became effective by January 1, 2008 for most U.S. companies and some believe that this caused the problem. Oppositely, a wider group of interested parties and investors believe that fair value increases transparency and give relevant information for decision making. Depending on the financial reporting framework and the going concern assumption, this paper investigates the process for determining fair value measurements and its in-depth effects in financial reports. Also, the paper will try to highlight the question: “Can fair value be really the main reason of the global financial crisis?” from the aspect of an accounting academician.

    Full Text Available The current global financial crisis is considered as one of the biggest crises after the crisis of the years of 30’s. The global financial crisis has affected all countries including developed and developing ones. It also has affected all the industries. Population with the low-income faced the greatest consequences. The last hope for the survival of the market economy was to undertake important steps for the nationalization of bankrupted banks and companies, thereby developing policies for the preservation of jobs. Through this analysis, we have included briefly some of the development followed the period of 2008 and onwards. A summary of statistics for some important economic indicators such as employment, exporting and importing is covered in this study as well.

    Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. By September 30, 2004, full PACS implementations in their facilities were 88.1% in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 110 hospitals). Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

    A pilot study is currently being carried out by ENIQ (European Network for Inspection Qualification) in order to explore the issues involved in inspection qualification applied along the general principles of the European methodology. The components selected for the pilot study are austenitic pipe to pipe and pipe to elbows welds typical of those in BWR recirculation loops. A range of defect parameters has been defined. A suitable inspection procedure designed to find the designated defects will be applied to geometrically representative test pieces. The procedure/equipment will be qualified through open trials and technical justification. The personnel qualification will be done in a blind way. Once all features of the inspection system will have been qualified an in-service inspection will be simulated in order to test the feasibility of the qualification approach followed. In this paper the current status of this pilot study is discussed. (orig.)

    The International VLBI Service for Geodesy and Astrometry (IVS) is a globally operating service that coordinates and performs Very Long Baseline Interferometry (VLBI) activities through its constituent components. The VLBI activities are associated with the creation, provision, dissemination, and archiving of relevant VLBI data and products. The products mostly pertain to the determination of the celestial and terrestrial reference frames, the Earth orientation parameters (EOP), atmospheric parameters as well as other ancillary parameters. The IVS observational network currently consists of about 40 radio telescopes worldwide. Subsets of these telescopes (8-12 stations) participate in 24-hour observing sessions that are run several times per week and in 1-hour intensive sessions for UT1 determination every day. The current VLBI network was developed mainly in the 1970s and 1980s. A number of factors, including aging infrastructure and demanding new scientific requirements, started to challenge its future sustainability and relevance. In response, the IVS and other groups developed and started implementing the next generation VLBI system, called VGOS (VLBI Global Observing System), at existing and new sites. The VGOS network is expected to reach maturity in the early 2020s. We describe the current status, progress, and anticipated prospects of geodetic/astrometric VLBI and the IVS.

    Iaccarino, Vittorio; Venetucci, Pietro

    2012-01-01

    Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

    2007-01-01

    Full Text Available Edible vaccines hold great promise as a cost-effective, easy-to-administer, easy-to-store, fail-safe and socioculturally readily acceptable vaccine delivery system, especially for the poor developing countries. It involves introduction of selected desired genes into plants and then inducing these altered plants to manufacture the encoded proteins. Introduced as a concept about a decade ago, it has become a reality today. A variety of delivery systems have been developed. Initially thought to be useful only for preventing infectious diseases, it has also found application in prevention of autoimmune diseases, birth control, cancer therapy, etc. Edible vaccines are currently being developed for a number of human and animal diseases. There is growing acceptance of transgenic crops in both industrial and developing countries. Resistance to genetically modified foods may affect the future of edible vaccines. They have passed the major hurdles in the path of an emerging vaccine technology. Various technical obstacles, regulatory and non-scientific challenges, though all seem surmountable, need to be overcome. This review attempts to discuss the current status and future of this new preventive modality.

    Highlights: • The implementation of MDSplus in TCABR tokamak, current status. • Interfaces between the system already installed and the MDSplus. • Web MDSplus interface. - Abstract: Experimental data for the TCABR tokamak is currently stored in MDSplus (Model Driven System Plus) database. The access to the data recorded during the experiments is performed using tools and libraries available by MDSplus system. The MDSplus system is widely used in different physics experiments, especially in plasmas physics and nuclear fusion. This standardized environment enables easy interaction among scientists of different experiments in different countries without the need to understand the particular characteristics of control, data acquisition and analysis, and remote access (CODAS) customized in each laboratory. In the first phase of implementation, intermediate interfaces had been developed between the legacy proprietary system and the MDSplus. In a second phase, the new diagnostic systems had been directly included in the created MDSplus system in the laboratory. After three years of use, the system installed on TCABR proved extremely efficient and significantly increased productivity in data analysis by involved scientists, regardless of whether they are locally at the TCABR, or accessing the system remotely from their home laboratories. The third phase, and subject of this article, are the development and implementation of the following systems: (i) web tools for the visualization of data, integrated with the experiment logbook, (ii) integration of MDSplus with applications (LabVIEW + MDSplus) and newer data acquisition hardware.

    The DPRK has developed Yongbyon Nuclear Complex in Figure 1 since 1960's. Currently it is composed of the reactor facility, fuel fabrication facility including the enrichment center, and the radiochemistry center. Even though many facilities are not modern and economic in the western standards, Yongbyon Nuclear Complex is fully equipped with the entire life cycle of the nuclear installation. The key facilities have been added step by step. For example, the DPRK's nuclear reactor fleet started with the 2 MW IRT-2000 reactor in the middle of 80's. It started with a small scale radioactive isotope separation center nearby. But nowadays the DPRK is constructing a much more larger isotope separation center in the vicinity of its enrichment center along with a potential new UF6 conversion center. The general description over Yongbyon Nuclear Complex is given in this paper. More detailed context of the current status of the center will be discussed in the main symposium purely based on the open source information study.

    The sagebrush (Artemisia spp.) biome has changed since settlement by Europeans. The current distribution, composition and dynamics, and disturbance regimes of sagebrush ecosystems have been altered by interactions among disturbance, land use, and invasion of exotic plants. In this chapter, we present the dominant factors that have influenced habitats across the sagebrush biome. Using a large-scale analysis, we identified regional changes and patterns in “natural disturbance”, invasive exotic species, and influences of land use in sagebrush systems. Number of fires and total area burned has increased since 1980 across much of the sagebrush biome. Juniper (Juniperus spp.) and pinyon (Pinus spp.) woodlands have expanded into sagebrush habitats at higher elevations. Cheatgrass (Bromus tectorum), an exotic annual grass, has invaded much of lower elevation, more xeric sagebrush landscapes across the western portion of the biome. Consequently, synergistic feedbacks between habitats and disturbance (natural and human-caused) have altered disturbance regimes, plant community dynamics and contributed to loss of sagebrush habitats and change in plant communities. Habitat conversion to agriculture has occurred in the highly productive regions of the sagebrush biome and influenced up to 56% of the Conservation Assessment area. Similarly, urban areas, and road, railroad, and powerline networks fragment habitats, facilitate predator movements, and provide corridors for spread of exotic species across the entire sagebrush biome. Livestock grazing has altered sagebrush habitats; the effects of overgrazing combined with drought on plant communities in the late 1880s and early 1900s still influences current habitats. Management of livestock grazing has influenced sagebrush ecosystems by habitat treatments to increase forage and reduce sagebrush and other plant species unpalatable to livestock. Fences, roads, and water developments to manage livestock movements have further

    With the first generation of ground-based gravitational wave laser interferometers already taking data, the availability of reliable waveform templates from astrophysical sources, which may help extract the signal from the anticipated noisy data, is urgently required. Gravitational stellar core collapse supernova has traditionally been considered among the most important astrophysical sources of potentially detectable gravitational radiation. Only very recently the first multidimensional simulations of relativistic rotational core collapse have been possible (albeit for models with simplified input physics), thanks to the use of conservative formulations of the hydrodynamics equations and advanced numerical methodology, as well as stable formulations of Einstein's equations. In this paper, the current status of relativistic core collapse simulations is discussed, with the emphasis given to the modelling of the collapse dynamics and to the computation of the gravitational radiation in the existing numerical approaches. Work employing the conformally-flat approximation (CFC) of the 3+1 Einstein's equations is reported, as well as extensions of this approximation (CFC+) and investigations within the framework of the so-called BSSN formulation of the 3+1 gravitational field equations (with no approximation for the spacetime dynamics). On the other hand, the incorporation of magnetic fields and the MHD equations in numerical codes to improve the realism of core collapse simulations in general relativity, is currently an emerging field where significant progress is bound to be soon achieved. The paper also contains a brief discussion of magneto-rotational simulations of core collapse, aiming at addressing the effects of magnetic fields on the collapse dynamics and on the gravitational waveforms.

    This is a brief report on the current status of the new GAs cell based Laser ionization Setup (GALS) at the Flerov Laboratory for Nuclear Reactions (FLNR) of the Joint Institute for Nuclear Research (JINR) in Dubna. GALS will exploit available beams from the U-400M cyclotron in low energy multi-nucleon transfer reactions to study exotic neutron-rich nuclei located in the “north-east” region of nuclear map. Products from 4.5 to 9 MeV/nucleon heavy-ion collisions, such as {sup 136}Xe on {sup 208}Pb, are thermalized and neutralized in a high pressure gas cell and subsequently selectively laser re-ionized. In order to choose the best scheme of ion extraction the results of computer simulations of two different systems are presented. The first off- and online experiment will be performed on osmium atoms that is regarded as a most convenient element for producing isotopes with neutron number in the vicinity of the magic N = 126.

    Artificial organs and regenerative medicine are the subjects of very active research and development (R&D) in Japan and various artificial organs are widely used in patients. Results of the R&D are presented at the annual conference of the Japanese Society for Artificial Organs (JSAO). Progress in the fields of artificial organs and regenerative medicine are reviewed annually in the Japanese Journal of Artificial Organs. The official English-language journal of JSAO, Journal of Artificial Organs, also publishes many original articles by Japanese researchers. Although the annual conference and the publications of JSAO provide the world with update information on artificial organs and regenerative medicine in Japan, the information is not always understood appropriately in the rest of the world, mainly due to language problems. This article therefore introduces the current status of artificial organs and regenerative medicine in Japan. Artificial hearts and metabolic support systems are reviewed here and other interesting areas such as regenerative medicine can be found elsewhere.

    The agrochemical industry is continuously searching for new pesticides to develop products with optimal efficacy, lower application rates in the field, increased selectivity, favorable toxicological and environmental safety, enhanced user friendliness and better economic viability. One strategy to achieve these ambitious goals makes use of the unique properties of molecules containing asymmetric centers. In the past, many natural products and their congeners have been a source of inspiration for designing new active ingredients, and the molecular structure of the resulting molecules have become increasingly complex. 30% contain fragments with asymmetric centers. However, despite the enormous progress that has been made in catalytic asymmetric processes over the last decade, only few agrochemicals are produced in enantiomerically pure or enriched form on an industrial scale. Since 2007, around 43% of the 44 launched products (insecticides, acaricides, fungicides, nematicides, and herbicides) contain one or more asymmetric centers in the molecule (≈ 47 %) and most of them were launched as racemic mixtures of enantiomers or diastereomers. This review gives an overview of the current status of chiral agrochemicals launched over the past 10 years and describes the inherently connected challenges of modern agricultural chemistry by managing important aspects resulting from stereochemistry of these innovative products.

    In 1961, the first Thai Research Reactor, TRR-1, having power of 1 MW was established. It was located at Office of Atomic Energy for Peace (OAEP) in Bangkok. TRR-1 was completely commissioned in June 1962. Plate typed high-enriched uranium (HEU) and U 3 O 8 -Al were used as fuel. Light water used as moderator and coolant. During 1975-1977, TRR-1 was shut down for modification. The reactor core and control system were disassembled and replaced by TRIGA Mark III. It is a circular hexagonal core typed reactor designed by General Atomics Company (GA). Afterwards, TRR-1 was officially renamed to Thai Research Reactor 1/Modification 1 (TRR-1/M1). TRR-1/M1 is a multipurpose reactor with nominal power of 2 MW. This swimming pool typed reactor uses low-enriched uranium (LEU) as fuel and light water as coolant and moderator. To date, the reactor has been operated with core No.12 that released power 1135 MWD to serve the user. The reactor has been serving for various kinds of utilization, for example, to produce radioisotope, neutron beam experiments and reactor physics experiments. This report explains in detail regarding operational experience and current status of this reactor, for example, reactor operation and reactor utilization. (author)

    Diabetes is a serious chronic condition,which increase the risk of cardiovascular diseases,kidney failure and nerve damage leading to amputation.Furthermore the ocular complications include diabetic macular edema,is the leading cause of blindness among adults in the industrialized countries.Today,blindness from diabetic macular edema is largely preventable with timely detection and appropriate interventional therapy.The treatment should include an optimized control of glycemia,arterial tension,lipids and renal status.The photocoagulation laser is currently restricted to focal macular edema in some countries,but due the high cost of intravitreal drugs,the use of laser treatment for focal and diffuse diabetic macular edema(DME),can be valid as gold standard in many countries.The intravitreal anti vascular endothelial growth factor drugs(ranibizumab and bevacizumab),are indicated in the treatment of all types of DME,but the correct protocol for administration should be defined for the different Retina Scientific Societies.The corticosteroids for diffuse DME,has a place in pseudophakic patients,but its complications restricted the use of these drugs for some patients.Finally the intravitreal interface plays an important role and its exploration is mandatory in all DME patients.

    Since 2010 August, PEFP(Proton Engineering Frontier Project)'s Proton Accelerator Research Center has been under construction so far. Generally, in advance of construction startup, many kinds of licenses should be acquired along with the types of construction works. To acquire a license in time, each item should meet the standard by the related regulation, including not only procedural but also content aspect. In the advent of internet era, electronic government system has been adopted in many governmental functions: So is the national construction license acquisition system. Owing to the system, both approval and documentation functions in licensing are integrated in online computer network which provide us simplification in process and easy accessibility to license data. However, aside from these construction licenses, other types of licenses still remain separately managed: Machinery, electric facilities, and so on. Moreover, all the licenses have the priority order and take legal term in processing. So, to avoid any time delay in license acquisition, we organized license hierarchy and found out the priority among them. Thereafter, according to their legal term in approval and acquisition, whole license acquisition schedule was arranged and we completed all the necessary licenses acquisition in time In this study, we summarize the current status of license acquisition on Proton Accelerator Research Center Construction, and manifest how they have been and will be managed systematically

    Current status of JENDL-3.3 is presented. Reevaluation work toward JENDL-3.3 has started last April for three years project to supply a consolidated new versions of JENDL by JAERI NDC (Nuclear Data center) with the cooperation of JNDC (Japanese Nuclear Data Committee). The working schedule has been fixed by the careful review of the summary report, `The problems of JENDL-3.2`, submitted to JNDC last March after one year discussions by a small advisory group: `Identifying the problems of JENDL-3.2`. To cope with the problems, two new subgroups are set up in the Subcommittee of Nuclear Data of JNDC. One is Heavy Mass Elements Evaluation Working Group for the re-evaluation of major actinides (Th-232, U-233,235,236,238, Pu-236,239,241,242). The other is Intermediate Mass Elements Evaluation Working Group for solving the inconsistencies between calculations and integral experiments relating to the fields of fusion neutronics and shielding applications as well as new evaluations such as Er elements. Supplying covariance data for important nuclides are one of the main feature of JENDL-3.3. Re-evaluated data will be released as JENDL-3.3 in the individual bases after the reviewing process by the experts. (author)

    The ITER-FEAT Electron Cyclotron System employs one equatorial launcher and three upper port launchers to inject 20 + 20 MW of mm-wave power at 170 GHz through slots in the plasma-facing neutron and radiation shield. The equatorial launcher includes 3 sets of toroidally steer-able mirrors, each collecting 8 RF beams from 24 circular cross-section corrugated wave-guides. In the upper-port launcher, eight beams, reflected in pairs by four toroidally angled (∼30 angle) and poloidally steer-able (∼ 10 angle) mirrors focus of the RF power on the plasma m = 2 and m = 3/2 plasma flux rational surfaces, for neo-classical tearing mode(s) (NTM) control. Conceptual studies of remote steering that would possibly allow removing the beam- steering equipment from the vacuum vessel and locating them in more protected positions have been carried out. All EC wave transmission is based on low losses circular cross section corrugated and evacuated wave guides each connected to a 170 GHz, 1 MW CW Gyrotron tube oscillator featuring an overall efficiency of ∼ 50%, obtained by depressed-collector energy recovery. In the paper, requirements, issues and the current status of the design is reviewed. (authors)

    Current antiviral treatments can reduce HIV-associated morbidity, prolong survival, and prevent HIV transmission. Combination antiretroviral therapy (cART) containing preferably three active drugs from two or more classes is required for durable virologic suppression. Regimen selection is based on virologic efficacy, potential for adverse effects, pill burden and dosing frequency, drug-drug interaction potential, resistance test results, comorbid conditions, social status, and cost. With prolonged virologic suppression, improved clinical outcomes, and longer survival, patients will be exposed to antiretroviral agents for decades. Therefore, maximizing the safety and tolerability of cART is a high priority. Emergence of resistance and/or lack of tolerability in individual patients require availability of a range of treatment options. Development of new drugs is focused on improving safety (e.g. tenofovir alafenamide) and/or resistance profile (e.g. doravirine) within the existing drug classes, combination therapies with improved adherence (e.g. single-tablet regimens), novel mechanisms of action (e.g. attachment inhibitors, maturation inhibitors, broadly neutralizing antibodies), and treatment simplification with infrequent dosing (e.g. long-acting injectables). In parallel with cART innovations, research and development efforts focused on agents that target persistent HIV reservoirs may lead to prolonged drug-free remission and HIV cure.

    Furman, W.I.

    1997-01-01

    A current status and a corrected time-schedule of the project of the new Intense Resonance Neutron pulsed source (IREN) realized in JINR (Dubna) for experiments dealing with fundamental and applied nuclear physics studies are discussed. This source is the upgraded variant of the existing IBR-30 pulsed booster. It consists of the 200 MeV electron linac and supplying by an electron beam the photo-neutron converter placed in the center of the very fast multiplying subcritical core. The existing buildings and beam infrastructure are planned to adopt for the new IREN source. The aim of the project is to improve essentially an energy resolution of the time-of-flight spectrometer and to increase twice (up to 10 15 n/sec) an integral neutron yield. An implementation of the IREN project has started in June 1994 with the planned end in December 1997. But due to mainly insufficient financing the approved time-schedule is shifted. Now most optimistic time of start-up of the neutron source is the end of 1999

    Full Text Available The aim of this study is to test for the relevance of some financial ratios as descriptors of companies’ financial status in explaining the evolutions of their business turnover. We are considering a data sample of 36 companies quoted on the Romanian capital market for a time span between 2007 and 2010.The predictive capacity of some significant financial ratios for the companies’ business turnover is analyzed and a methodology for the evaluation of their financial status based on these ratios is advanced. We found that the predictive capacity of some relevant financial ratios for the dynamic of some quoted companies’ turnovers is non-uniform across the two conventional sectors in which we have grouped these companies according to their field of activity. Based on these results, an synthetic indicator of the companies’ financial status is constructed at the level of each individual sector and the non-linear correlation between this indicator and the business turnover is tested.

    The JMTR is a light water moderated and cooled, beryllium reflected tank- type reactor using LUE silicide plate-type fuels. Its thermal power is 50 MW, maximum thermal and fast neutron flux is 4x10 18 m -2 s -1 . First criticality was achieved in March 1968, and its operation was stopped from August, 2006 for the refurbishment. The refurbishment is scheduled from the beginning of FY2007 to the end of FY2010. The renewed and upgraded JMTR will be re-started from FY2011. An investigation on aged components (aged-investigation) was carried out for concrete structures of the JMTR reactor building, exhaust stack, etc., and for tanks in the primary cooling system, heat exchangers, pipes in the secondary cooling system, cooling tower, emergency generators and so on, in order to identify their integrity. The aged-investigation was carried out at the beginning of FY2007. As a result, some components were decided to replace from viewpoints of future maintenance and improvement of reliability, and some components or structures were decided to repair. A visual inspection of inner side of the pressure vessel was carried out using an underwater camera in FY2008, and no serious damage was observed. Up to now, refurbishment works are in progress according to the planned schedule. In FY2009, motors of primary cooling pumps, secondary cooling pumps, motors of drain pumps, pump in the primary water transfer line to the water purification system, beryllium reflector frame, low-voltage motor control centers are to be replaced. A nuclear instrumentation system, process control system, safety protection system and so on are to be replaced in FY2010. In this paper, current status of JMTR refurbishment project is presented.

    The aim of this review is to report on the current status of prostate-specific membrane antigen (PSMA)-directed theranostics in prostate cancer (PC) patients. The value of {sup 68}Ga-PSMA-directed PET imaging as a diagnostic procedure for primary and recurrent PC as well as the role of evolving PSMA radioligand therapy (PRLT) in castration-resistant (CR)PC is assessed. The most eminent data from mostly retrospective studies currently available on theranostics of prostate cancer are discussed. The current knowledge on {sup 68}Ga-PSMA PET/CT implicates that primary staging with PET/CT is meaningful in patients with high-risk PC and that the combination with pelvic multi parametric (mp)MR (or PET/mpMR) reaches the highest impact on patient management. There may be a place for {sup 68}Ga-PSMA PET/CT in intermediate-risk PC patients as well, however, only a few data are available at the moment. In secondary staging for local recurrence, {sup 68}Ga-PSMA PET/mpMR is superior to PET/CT, whereas for distant recurrence, PET/CT has equivalent results and is faster and cheaper compared to PET/mpMR. {sup 68}Ga-PSMA PET/CT is superior to {sup 18}F / {sup 11}Choline PET/CT in primary staging as well as in secondary staging. In patients with biochemical relapse, PET/CT positivity is directly associated with prostate-specific antigen (PSA) increase and amounts to roughly 50% when PSA is raised to ≤0.5 ng/ml and to ≥90% above 1 ng/ml. Significant clinical results have so far been achieved with the subsequent use of radiolabeled PSMA ligands in the treatment of CRPC. Accumulated activities of 30 to 50 GBq of {sup 177}Lu-PSMA ligands seem to be clinically safe with biochemical response and PERCIST/RECIST response in around 75% of patients along with xerostomia in 5-10% of patients as the only notable side effect. On the basis of the current literature, we conclude that PSMA-directed theranostics do have a major clinical impact in diagnosis and therapy of PC patients. We recommend

    In this review, we discuss the current status of research in nuclear physics which is being carried out in different centers in the world. For this purpose, we supply a short account of the development in the area which evolved over the last nine decades, since the discovery of the neutron. The evolution of the physics of the atomic nucleus went through many stages as more data became available. We briefly discuss models introduced to discern the physics behind the experimental discoveries, such as the shell model, the collective model, the statistical model, the interacting boson model, etc., some of these models may be seemingly in conflict with each other, but this was shown to be only apparent. The richness of the ideas and abundance of theoretical models attests to the important fact that the nucleus is a really singular system in the sense that it evolves from two-body bound states such as the deuteron, to few-body bound states, such as 4 He, 7 Li, 9 Be, etc. and up the ladder to heavier bound nuclei containing up to more than 200 nucleons. Clearly, statistical mechanics, usually employed in systems with very large number of particles, would seemingly not work for such finite systems as the nuclei, neither do other theories which are applicable to condensed matter. The richness of nuclear physics stems from these restrictions. New theories and models are presently being developed. Theories of the structure and reactions of neutron-rich and proton-rich nuclei, called exotic nuclei, halo nuclei, or Borromean nuclei, deal with the wealth of experimental data that became available in the last 35 years. Furthermore, nuclear astrophysics and stellar and Big Bang nucleosynthesis have become a more mature subject. Due to limited space, this review only covers a few selected topics, mainly those with which the authors have worked on. Our aimed potential readers of this review are nuclear physicists and physicists in other areas, as well as graduate students interested

  5. CURRENT CONCEPTS ON SELECTION TECHNIQEUS IN FINANCIAL AUDITING

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available The financial auditor's work evolves around the issue of an independent, professional and objective opinion on the compliance of the client's financial statements with the national accounting rules and principles. At the same time, the auditor will have to express an opinion on the ability of the company to continue its activity. An ideal situation would involve auditing all the components of the yearly accounts, but this would take time, effort and a very high cost. Fortunately, the audit team has some very useful tools for acquiring audit evidence in a fast and conclusive way - selection techniques. These techniques may be used in different phases of the audit and auditors have been using them for a long time, in fact no audit program would function without these techniques. They have become quite common as the auditors make important judgments, such as determining what type of technique to apply, whether to use statistical or nonstatistical techniques, appropriate inputs to determine sample size, and evaluation of results, particularly when errors are detected. This paper aims to theoretically present the main selection techniques, indicating how, why and when to use them. There are six selection techniques and we deal with the most frequent four of them. Our purpose is to present the characteristics and set the limits of these techniques, emphasizing sampling as the most common selection technique currently in use. A commonly held misconception about statistical sampling, for example, is that it removes the need for the use of the professional judgement. While it is true that statistical sampling uses statistical methods to determine the sample size and to select and evaluate audit samples, it is the responsibility of the auditor to consider and specify in advance factors such as materiality, the expected error rate or amount, the risk of over-reliance or the risk of incorrect acceptance, audit risk, inherent risk, control risk, standard

  10. Current Status of Deep Geological Repository Development

    Budnitz, R J

    2005-01-01

    This talk provided an overview of the current status of deep-geological-repository development worldwide. Its principal observation is that a broad consensus exists internationally that deep-geological disposal is the only long-term solution for disposition of highly radioactive nuclear waste. Also, it is now clear that the institutional and political aspects are as important as the technical aspects in achieving overall progress. Different nations have taken different approaches to overall management of their highly radioactive wastes. Some have begun active programs to develop a deep repository for permanent disposal: the most active such programs are in the United States, Sweden, and Finland. Other countries (including France and Russia) are still deciding on whether to proceed quickly to develop such a repository, while still others (including the UK, China, Japan) have affirmatively decided to delay repository development for a long time, typically for a generation of two. In recent years, a major conclusion has been reached around the world that there is very high confidence that deep repositories can be built, operated, and closed safely and can meet whatever safety requirements are imposed by the regulatory agencies. This confidence, which has emerged in the last few years, is based on extensive work around the world in understanding how repositories behave, including both the engineering aspects and the natural-setting aspects, and how they interact together. The construction of repositories is now understood to be technically feasible, and no major barriers have been identified that would stand in the way of a successful project. Another major conclusion around the world is that the overall cost of a deep repository is not as high as some had predicted or feared. While the actual cost will not be known in detail until the costs are incurred, the general consensus is that the total life-cycle cost will not exceed a few percent of the value of the

    Full text: The first nuclear research reactors (RR) appeared in the 1940s. Their initial purpose was to provide knowledge of the main processes associated with neutron-induced nuclear reactions. Later, the rang of problems addressed expanded substantially. Besides fundamental research in the properties of matter, such reactors are successfully used for dealing with problems in the fields of materials science, nuclear engineering, medicine, isotope production, education, etc. Over the whole period of RR fleet growth, more than six hundred nuclear research facilities were built in 70 countries of the world. As of the end of 2008, the number of Russian research reactors in service was about 20% of the globally operating RR fleet. This paper discusses the current status of the world's RR fleet and describes the capabilities of the experimental reactor facilities existing in Russia. In the 21st century, research reactors will remain in demand to solve scientific and technological problems for innovative development of society. The emerging renaissance of nuclear power, the expanding RR uses for production of isotopes and other applications, the increase in the number of countries willing to use nuclear technologies in energy production, industry and science - all contribute to a rebirth of interest in research reactors. One of the ways to improve the experimental capabilities lies in radical upgrading of the reactor facilities with qualitative changes in the main neutronic characteristics of the core. The associated design approaches are illustrated with the example of the IBR-2M reactor at the JNRI in Dubna. The imperative need restricting the spread of nuclear threat leads us to give up using highly enriched uranium in most research reactors. Development of RR fuel with reduced enrichment in uranium has been one of the priority objectives of NIKIET for many years. This paper presents the latest results obtained along these lines, as applied to pool-type research

    A review of the regulatory status of herbal drugs/products was done for few countries forming part of Asia, Africa, America, Europe, and Australia, to understand various categories under which the trade of herbal products is permitted and their premarketing requirements. A critical assessment was done, to know the hindrances in the process of harmonization of herbal products. It has been found that there is a lack of harmonization in the regulatory requirements of herbal products internationally, besides the issues of availability of herbs and their conservation. These are hindering the international trade and growth of the herbal products segment. PMID:26681886

    Full Text Available Human exposure to ionizing radiation disrupts normal metabolic processes in cells and organs by inducing complex biological responses that interfere with gene and protein expression. Conventional dosimetry, monitoring of prodromal symptoms and peripheral lymphocyte counts are of limited value as organ and tissue specific biomarkers for personnel exposed to radiation, particularly, weeks or months after exposure. Analysis of metabolites generated in known stress-responsive pathways by molecular profiling helps to predict the physiological status of an individual in response to environmental or genetic perturbations. Thus, a multi-metabolite profile obtained from a high resolution mass spectrometry-based metabolomics platform offers potential for identification of robust biomarkers to predict radiation toxicity of organs and tissues resulting from exposures to therapeutic or non-therapeutic ionizing radiation. Here, we review the status of radiation metabolomics and explore applications as a standalone technology, as well as its integration in systems biology, to facilitate a better understanding of the molecular basis of radiation response. Finally, we draw attention to the identification of specific pathways that can be targeted for the development of therapeutics to alleviate or mitigate harmful effects of radiation exposure.

    This paper describes the current energy sector in Ecuador, its present structure, the oil industry, subsidies, and renewable energy, focusing on the evolution and reform of the electricity sector. Currently, 86% of the primary energy originates from nonrenewable sources. In 2005, the gross electricity generation was 15 127 GWh (45.5% hydropower, 43.11% thermal, and 11.39% imported). Ecuador is the fifth largest oil producer in South America but lacks sufficient oil refining capacity. Reserves of natural gas (NG) are small, and most of NG is produced from oil fields without energy recovery. Several projects are underway to increase the utilization of NG and renewable energies to meet Ecuador commitments to the Kyoto Protocol

    We review the most recent data from e + e - and p bar p colliders and discuss the resulting constraints on the parameters of the Minimal Supersymmetric Standard Model, and their implications for future supersymmetry searches. We review the patterns of cascade decays of squarks and gluinos and discuss the present status of supersymmetry event generators for hadron colliders. We present the results of detailed simulations of E T and same sign dilepton events from supersymmetry at the Tevatron. Although the E T signal continues to be viable, it is concluded that the same sign dilepton signal may be too small unless squarks and gluinos are approximately degenerate. The E T and the same-sign dilepton signals from supersymmetry and the Standard Model backgrounds at the SSC are also discussed in detail. We also discuss other promising ways of searching for supersymmetry at the SSC including events containing Z degree bosons, and events containing n isolated leptons (n ≥ 3). Finally, we discuss how supersymmetry searches might be modified if the Higgs sectors is more complicated or if R-parity is not conserved due to baryon number violating interactions. 49 refs., 12 figs

    Theobroma cacao-The Food of the Gods, provides the raw material for the multibillion dollar chocolate industry and is also the main source of income for about 6 million smallholders around the world. Additionally, cocoa beans have a number of other nonfood uses in the pharmaceutical and cosmetic industries. Specifically, the potential health benefits of cocoa have received increasing attention as it is rich in polyphenols, particularly flavonoids. At present, the demand for cocoa and cocoa-based products in Asia is growing particularly rapidly and chocolate manufacturers are increasing investment in this region. However, in many Asian countries, cocoa production is hampered due to many reasons including technological, political and socio-economic issues. This review provides an overview of the present status of global cocoa production and recent advances in biotechnological applications for cacao improvement, with special emphasis on genetics/genomics, in vitro embryogenesis and genetic transformation. In addition, in order to obtain an insight into the latest innovations in the commercial sector, a survey was conducted on granted patents relating to T. cacao biotechnology. © 2017 The Authors.

    The purpose of this study was to evaluate and categorize current state-sponsored opioid guidelines for the practice of emergency medicine (EM). We conducted a comprehensive search of EM-specific opioid prescribing guidelines and/or policies in each state to determine current state involvement in EM opioid prescribing, as well as to evaluate some of the specifics of each guideline or policy. The search was conducted using an online query and a follow-up email request to each state chapter of ACEP. We found that 17 states had emergency department-specific guidelines. We further organized the guidelines into four categories: limiting prescriptions for opioids with 67 total recommendations; preventing/diverting abuse with 56 total recommendations; addiction-related guidelines with 29 total recommendations; and a community resources section with 24 total recommendations. Our results showed that current state guidelines focus on providers limiting opioid pain prescriptions and vetting patients for possible abuse/diversion. This study highlights the 17 states that have addressed opioid prescribing guidelines and categorizes their efforts to date. It is hoped that this study will provide the basis for similar efforts in other states.

    Fast Reactor development experiences and status in Japan are summarized. Even though international SFR circumstances were against in 1980s and 1990s, e.g. CRBRP, SNR-300 and Superphenix terminations, we kept on with our R and D activities steadily aiming at positive development targets in Japan. As results of our efforts, it has shown that our commercialized SFR concept, Japan Sodium-cooled Fast Reactor (JSFR) could meet the targets in the Feasibility Study on Commercialized Fast Reactor Cycle Systems (FS) and the Fast Reactor Cycle Technology Development (FaCT) project. Further, Monju has finally achieved restart in May 2010 after having been shut for almost 15 years. A future plan of Monju is to be determined based on a direction of the national nuclear and energy policies that will be established in 2012. The undergoing FaCT project is pursuing commercialization of fast reactor cycle system around 2050 under cooperation of MEXT (Ministry of Education, Culture, Sports, Science and Technology), METI (Ministry of Economy, Trade and Industry), utilities, venders and JAEA (Japan Atomic Energy Agency). As results of the FaCT Phase I, feasibility of the key technologies for JSFR has been evaluated and the project is waiting for launching the phase II due to the Tohoku large earthquake. It is considered that the nuclear development policy might be affected by the Tohoku large Earthquake/Tsunami in Japan. Nevertheless the significance of nuclear energy will not be changed and thus we will focus on the issues learnt from Fukushima accidents and reflect into the improvement of the safety of Monju and the safety design criteria for the next generation Fast Reactor systems.

    There are about 6000 new glioblastoma multiform brain tumours diagnosed each year in the United States of America alone. This cancer is usually fatal within six months of diagnosis even with current standard treatments. Research on boron neutron capture therapy (BNCT) has been considered as a method of potentially curing such cancers. There is a great interest at under-utilised research reactors institutions to identify new medical utilization, attractive to the general public. Neutron capture therapy is a true multidisciplinary topic with a large variety of individuals involved. This publication attempts to provide current information for all those thinking about being involved with NCT, based on the knowledge and experience of those who have pioneered the treatment. It covers the whole range of NCT from designing reactor conversions or new facilities, through to clinical trials and their effectiveness. However, since most work has been done with boron capture therapy for brain tumours using modified thermal research reactors, this tends to be the focus of the report. One of the factors which need to be addressed at the beginning is the timing of the further development of NCT facilities. It should be emphasised that all current work is still at the research stage. Many of those now involved believe that there is little need for many more research facilities until such time as the treatment shows more promising results. For this and other reasons discussed in the report, very serious consideration should be given by research reactor owners and operators before spending large sums of money converting their facilities for NCT.

    Full Text Available Family Health (FH has three main elements: individual health, life material conditions and family functioning. Its main actors are the individual, the family and society. A common framework is the basis of FH, as each one of these elements is extremely important. Currently, in Mexico two aspects are considered: epidemiological studies and those inherent to the family medicine specialty. That latter has a residency and an integrated specialty curriculum, as well as certification from the corresponding board. All of this allows us to apply the HF approach to each and every family and individual that is cared for.

    Many research efforts over the last few decades have been devoted to sensing lactate as an important analytical target in clinical care, sport medicine, and food processing. Therefore, research in designing lactate sensors is no longer in its infancy and now is more directed toward viable sensors for direct applications. In this review, we provide an overview of the most immediate and relevant developments toward this end, and we discuss and assess common transduction approaches. Further, we critically describe the pros and cons of current commercial lactate sensors and envision how future sensing design may benefit from emerging new technologies.

    Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

  20. Current status of nuclear engineering education

    1975-01-01

    The 65 colleges and universities offering undergraduate degrees in nuclear engineering and the 15 schools offering strong nuclear engineering options are, in general, doing a good job to meet the current spectrum of job opportunities. But, nuclear engineering programs are not producing enough graduates to meet growing demands. They currently receive little aid and support from their customers --industry and government--in the form of scholarships, grants, faculty research support, student thesis and project support, or student summer jobs. There is not enough interaction between industry and universities. Most nuclear engineering programs are geared too closely to the technology of the present family of reactors and too little to the future breeder reactors and controlled thermonuclear reactors. In addition, nuclear engineering programs attract too few women and members of minority ethnic groups. Further study of the reasons for this fact is needed so that effective corrective action can be taken. Faculty in nuclear engineering programs should assume greater initiative to provide attractive and objective nuclear energy electives for technical and nontechnical students in other disciplines to improve their technical understanding of the safety and environmental issues involved. More aggressive and persistent efforts must be made by nuclear engineering schools to obtain industry support and involvement in their programs

    Tissue engineering, which consists of the combination and in vivo implantation of elements required for tissue remodeling toward a specific organ phenotype, could be an alternative for classical techniques of esophageal replacement. The current hybrid approach entails creation of an esophageal substitute composed of an acellular matrix and autologous epithelial and muscle cells provides the most successful results. Current research is based on the use of mesenchymal stem cells, whose potential for differentiation and proangioogenic, immune-modulator and anti-inflammatory properties are important assets. In the near future, esophageal substitutes could be constructed from acellular "intelligent matrices" that contain the molecules necessary for tissue regeneration; this should allow circumvention of the implantation step and still obtain standardized in vivo biological responses. At present, tissue engineering applications to esophageal replacement are limited to enlargement plasties with absorbable, non-cellular matrices. Nevertheless, the application of existing clinical techniques for replacement of other organs by tissue engineering in combination with a multiplication of translational research protocols for esophageal replacement in large animals should soon pave the way for health agencies to authorize clinical trials.

  2. Current status of the RERTR program

    1983-01-01

    The main purpose of this paper is to review the progress which has been accomplished by the RERTR Program during the past year, the present status of the program, the activities which are now in progress, and the program plans for the coming years. The main program objectives have not changed during the past year. The primary goal of the RERTR Program is still to reduce the amount of HEU which is shipped and used around the world in research reactors and, with it, the nuclear proliferation potential which it creates. Also unchanged is the program objective to reduce HEU use without significant penalty to the reactors involved. This means that for every possible conversion, our technical goal is to achieve good experiment capabilities and the economic advantages that come from a long core lifetime and from relatively economical fuels. We also intend to limit as much as possible the modifications which may have to be made to the reactor in order to achieve conversion and, last but not least, we intend to avoid any significant problems that might appear in the safety and licensing areas. Other important goals are the sharing of information about reduced-enrichment technology and providing technical assistance to the U.S. Government on special problems that may affect implementation of its policies. The timetable of the RERTR Program has stretched slightly. At the time of the previous ANL Conference, a long range goal was set which was anticipated to require about five or six years. This happened in 1978 and, therefore, the long range goal was considered to be achievable by 1984. This final deadline, the time when the long term goal of technical convertibility of all research reactors can be achieved, has now been moved to 1986. In the meantime, good progress has been made towards the near-term goals. Much more detailed knowledge is available about what lies ahead from a technical point of view. In addition, the general level of confidence in the achievability of the

    Full Text Available School refusal behavior refers to the avoidance of a child attending school and/or persistent difficulty staying in the classroom throughout the school day. Based on a review of the scientific literature, the aim of this study is to describe the current state of research on school refusal, differentiating between the findings and progress made in Spain from those achieved in the international field. For this purpose, the significance of this phenomenon, in addition to associated risk factors and variables, will be reviewed in the child and youth population. In turn, the commonly used assessment methods and most recommended treatment proposals, mainly based on cognitive behavioral therapy, are discussed. The results reveal several gaps and subjects for debate in some areas of knowledge about school refusal behavior, with differences being found between Spanish and international studies. In conclusion, future studies and challenges in this field are required.

    Briasoulis, Alexander; Bakris, George L

    2016-11-01

    Over the past 7 years, prospective cohorts and small randomized controlled studies showed that renal denervation therapy (RDN) in patients with resistant hypertension is safe but associated with variable effects on BP which are not substantially better than medical therapy alone. The failure of the most rigorously designed randomized sham-control study, SYMPLICITY HTN-3, to meet the efficacy endpoints has raised several methodological concerns. However, recently reported studies and ongoing trials with improved procedural characteristics, identification of patients with true treatment-resistant hypertension on appropriate antihypertensive regimens further explore potential benefits of RDN. The scope of this review is to summarize evidence from currently completed studies on RDN and discuss future perspectives of RDN therapy in patients with resistant hypertension.

However, conventional handheld US (HHUS has several limitations such as operator dependence and the requirement of a considerable amount of radiologist time for whole-breast US. Automated breast US (ABUS, recently approved by the United States Food and Drug Administration for screening purposes, has several advantages over HHUS, such as higher reproducibility, less operator dependence, and less required physician time for image acquisition. In addition, ABUS provides both a coronal view and a relatively large field of view. Recent studies have reported that ABUS is promising in US screening for women with dense breasts and can potentially replace handheld second-look US in a preoperative setting.

    The International Laser Ranging Service (ILRS) is expanding its ground tracking capability with new stations and upgrades to current stations. Our Russian colleagues have installed new stations in Brasilia and South Africa, and have several other sites in process or in planning. The NASA Space Geodesy Program is preparing equipment for U.S. sites (McDonald and Haleakala) and with the Norwegian National Mapping Agency in Ny Ålesund; further deployments are planned. Upgrades continue at sites in China, and new sites are underway or planned in Europe and India. Stations are moving to higher repetition rates and more efficient detection to enhance satellite interleaving capability; some stations have already implemented automated processes that could lead to around-the-clock operation to increase temporal coverage and to make more efficient use of personnel. The ILRS roster of supported satellites continues to grow with the addition of the LARES satellite to augment tracking for the improvement of the ITRF. New GNSS constellations and geosynchronous satellites now bring the total roster to over 80 satellites - so much so, that new tracking strategies and time and location multiplexing are under consideration. There continues to be strong interest in Lunar Ranging. New applications of one-way and two-way laser ranging include ps-accurate time transfer, laser transponders for interplanetary ranging, and tracking of space debris. New laser ranging data products are being developed, including satellite orbit products, satellite orientation, gravity field products, and products to characterize the quality of data and station performance. This talk will give a brief summary of recent progress, current challenges and a view of the path ahead.

  9. Molecular imaging: current status and emerging strategies

    International Nuclear Information System (INIS)

    Pysz, M.A.; Gambhir, S.S.; Willmann, J.K.

    2010-01-01

    In vivo molecular imaging has a great potential to impact medicine by detecting diseases in early stages (screening), identifying extent of disease, selecting disease- and patient-specific treatment (personalized medicine), applying a directed or targeted therapy, and measuring molecular-specific effects of treatment. Current clinical molecular imaging approaches primarily use positron-emission tomography (PET) or single photon-emission computed tomography (SPECT)-based techniques. In ongoing preclinical research, novel molecular targets of different diseases are identified and, sophisticated and multifunctional contrast agents for imaging these molecular targets are developed along with new technologies and instrumentation for multi-modality molecular imaging. Contrast-enhanced molecular ultrasound (US) with molecularly-targeted contrast microbubbles is explored as a clinically translatable molecular imaging strategy for screening, diagnosing, and monitoring diseases at the molecular level. Optical imaging with fluorescent molecular probes and US imaging with molecularly-targeted microbubbles are attractive strategies as they provide real-time imaging, are relatively inexpensive, produce images with high spatial resolution, and do not involve exposure to ionizing irradiation. Raman spectroscopy/microscopy has emerged as a molecular optical imaging strategy for ultrasensitive detection of multiple biomolecules/biochemicals with both in vivo and ex vivo versatility. Photoacoustic imaging is a hybrid of optical and US techniques involving optically-excitable molecularly-targeted contrast agents and quantitative detection of resulting oscillatory contrast agent movement with US. Current preclinical findings and advances in instrumentation, such as endoscopes and microcatheters, suggest that these molecular imaging methods have numerous potential clinical applications and will be translated into clinical use in the near future.

    Four experiments are currently approved for the first measurements with colliding heavy ion beams from the Relativistic Heavy Ion Collider (RHIC) which is scheduled to come into operation in Spring 1999. These experiments are named STAR, Phoenix, PHOBOS and Brahms. It is expected that central collisions of 100 GeV/u Au + Au at RHIC will lead to energy densities far above any so far attained in the laboratory and it is suspected and hoped that this situation will lead to qualitatively new physics perhaps associated with the creation of a large volume containing a plasma of deconfined quarks and gluons. All four experiments attempt to search for signatures of new physics through combinations of measurements of quantities such as the multiplicity of produced particles, the average transverse momentum of these particles, fluctuations in their multiplicity distribution, their flavor composition, the size scales of the volume from which they are emitted, mass shifts and changes in the decay widths of resonances which decay inside the high energy density volume etc. The PHOBOS detector addresses these issues with a Multiplicity Array which covers the pseudo-rapidity region -5.3 ≤ η ≤ 5.3 with a coverage of 85% of 4π and also incorporates a Vertex Detector. The Multiplicity Array is complemented by two Multi-Particle Spectrometers, each of which cover the range 0.5 ≤ η ≤ 1.5 and azimuthal angle range Δφ = 11 degree. Various trigger and monitor detectors complete PHOBOS

  11. Advanced radiation chemistry research: Current status

    International Nuclear Information System (INIS)

    1995-10-01

    Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It is based on the use of ionizing radiation as the initiator or catalyst in chemical reactions. The most significant advantage of radiation chemistry lies in its ability to be used in the production and study of almost any reactive atomic and molecular species playing a part in chemical reaction, synthesis, industrial processes, or in biological systems. Over the the last few years a number of meetings have taken place, under the auspices of the IAEA, in order to evaluate recent developments in radiation chemistry as well as the trends indicated by the results obtained. Radiation chemists from different countries have participated at these meetings. The present publication, a companion to the previous publication - New Trends and Development in Radiation Chemistry, IAEA-TECDOC-527 (1989) - includes some of the important contributions presented at these meetings. It is hoped that it will provide a useful overview of current activities and of emerging trends in this field, thus promoting better understanding of potential contributions of radiation chemistry to other fields of knowledge as well as to practical applications in industry, medicine and agriculture.

    2018-06-01

    In this review, we will detail the evolution of endovascular therapy as the basis for the development of catheter-based robotics. In parallel, we will outline the evolution of robotics in the surgical space and how the convergence of technology and the entrepreneurs who push this evolution have led to the development of endovascular robots. The current state-of-the-art and future directions and potential are summarized for the reader. Information in this review has been drawn primarily from our personal clinical and preclinical experience in use of catheter robotics, coupled with some ground-breaking work reported from a few other major centers who have embraced the technology's capabilities and opportunities. Several case studies demonstrating the unique capabilities of a precisely controlled catheter are presented. Most of the preclinical work was performed in the advanced imaging and navigation laboratory. In this unique facility, the interface of advanced imaging techniques and robotic guidance is being explored. Although this procedure employs a very high-tech approach to navigation inside the endovascular space, we have conveyed the kind of opportunities that this technology affords to integrate 3D imaging and 3D control. Further, we present the opportunity of semi-autonomous motion of these devices to a target. For the interventionist, enhanced precision can be achieved in a nearly radiation-free environment.

    The MASHA setup designed as the mass-separator with the resolving power of about 1700, which allows mass identification of superheavy nuclides is described. The setup uses solid ISOL (Isotope Separation On-Line) method. In the present article the upgrade of some parts of MASHA are described: target box (rotating target + hot catcher), ion source based on electron cyclotron resonance, data acquisition, beam diagnostics and control systems. The upgrade is undertaken in order to increase the total separation efficiency, reduce the separation time, of the installation and working stability and make possible continuous measurements at high beam currents. Ion source efficiency was measured in autonomous regime with using calibrated gas leaks of Kr and Xe injected directly to ion source.

    Inside a tritium facility, calorimetry is an important analytical method as it is the only reference method for accountancy (it is based on the measurement of the heat generated by the radioactive decay). Presently, at Tritium Laboratory Karlsruhe (TLK), 4 calorimeters are in operation, one of isothermal type and three of inertial guidance control type (IGC). The volume of the calorimeters varies between 0.5 and 20.6 liters. About two years ago we started an extensive work to improve our calorimeters with regard to reliability and precision. We were forced to upgrade 3 of our 4 calorimeters due to the outdated interfaces and software. This work involved creating new LabView programs driving the devices, re-tuning control loops and replacing obsolete hardware components. In this paper we give a review on the current performance of our calorimeters, comparing it to recently available devices from the market and in the literature. We also show some ideas for a next generation calorimeter based on experiences with our IGC calorimeters and other devices reported in the literature. (authors)

    Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It is based on the use of ionizing radiation as the initiator or catalyst in chemical reactions. The most significant advantage of radiation chemistry lies in its ability to be used in the production and study of almost any reactive atomic and molecular species playing a part in chemical reaction, synthesis, industrial processes, or in biological systems. Over the the last few years a number of meetings have taken place, under the auspices of the IAEA, in order to evaluate recent developments in radiation chemistry as well as the trends indicated by the results obtained. Radiation chemists from different countries have participated at these meetings. The present publication, a companion to the previous publication - New Trends and Development in Radiation Chemistry, IAEA-TECDOC-527 (1989) - includes some of the important contributions presented at these meetings. It is hoped that it will provide a useful overview of current activities and of emerging trends in this field, thus promoting better understanding of potential contributions of radiation chemistry to other fields of knowledge as well as to practical applications in industry, medicine and agriculture.

    Efforts at nuclear safety research have expanded year by year in Japan, in term of money and technical achievement. The Atomic Energy Commission set last year the five year nuclear safety research program, a guideline by which various research institutes will be able to develop their own efforts in a concerted manner. From the results of the nuclear safety research which cover very wide areas ranging from reactor engineering safety, safety of nuclear fuel cycle facilities, prevention of radiation hazards to the adequate treatment and disposal of radioactive wastes, AIJ hereafter focuses of LWR engineering safety and prevents two articles, one introducing the current results of the NSSR program developed by JAERI and the other reporting the LWR reliability demonstration testing projects being promoted by MITI. The outline of these demonstration tests was reported in this report. The tests consist of earthquake resistance reliability test of nuclear power plants, steam generator reliability tests, valve integrity tests, fuel assembly reliability tests, reliability tests of heat affected zones and reliability tests of pumps.

    The CNS is currently reviewing the PBMR conceptual design from a licensibility point of view. The PBMR concept is based on a High Temperature Gas Cooled Reactor - pebble bed reactor type. It is anticipated that the PBMR design will rely on inherent safety characteristics to contain fission products within fuel over the full range of design basis events. This feature combined with the high temperature integrity of the fuel and structural graphite, allows the safe use of a high coolant temperature, which allows consideration of the future development of this reactor for non-electrical applications of nuclear heat for industrial use. The CNS licensing approach requires that the licensing and design basis of the plant should respect prevailing international norms and practices and that a quantitative risk assessment should demonstrate compliance with the CNS fundamental safety standards. The first stage of the licensing process is now ongoing; this is a pre-application phase, which will result in a statement on licensibility being issued. Identification of the specific documentation requirements and information needed is required across every step of the licensing process. Top level regulatory requirements have been established for the PBMR. They include the CNS fundamental safety standard and basic licensing criteria, which describes requirements on licensees of nuclear installations regarding risk assessment and compliance with the safety criteria and define classification of licensing basis events.

    To evaluate the current use of adrenalectomy in the treatment of Cushing's disease, we reviewed seven consecutive patients who have undergone adrenalectomy for Cushing's disease at this medical center during 1983 to 1984. Seventy-one percent (5/7) had pituitary, or type I, Cushing's disease, while 29% (2/7) had adrenal, or type II, Cushing's disease from either an adenoma or an adrenocortical carcinoma. Presenting signs and symptoms, either initially or at the time of recurrence, were typical of Cushing's syndrome. Four of five patients with type I disease had recurrent disease after transphenoidal hypophysectomy, bilateral adrenalectomy, or unilateral adrenalectomy. In three of five patients, medical therapy of hypercortisolism was abandoned because of adverse side effects. Preoperative evaluation in all patients included cortisol and ACTH levels, dexamethasone suppression tests, and computerized tomography (both abdominal and head). In patients with a prior history of adrenalectomy, radiocholesterol scans were also performed and were useful. Angiographic procedures were not required in these patients. In patients with type I disease, posterior operative approaches were used. In patients with type II disease, an anterolateral approach was used. Posterolateral incisions are preferred over Hugh-Young incisions and provide better exposure with a reduced risk of poor wound healing. Morbidity and mortality included one death and three nonhealing wounds. In the six surviving patients, symptoms resolved with variable frequency. Findings suggestive of Nelson's syndrome (hyperpigmentation) have occurred in two patients; serial computerized tomographic scans fail to reveal evidence of pituitary tumors

    The techniques of biologic resurfacing of the patella, like other joint surfaces, are still evolving. Currently none of them is free from criticism. In this regard it is our hope that progress in the basic science will offer in the near future new and more optimistic therapeutic possibilities (i.e., the restoration of a reparative cartilage that is structurally and functionally comparable to the native one). The greater expectancies come perhaps from the present experimental investigations about the combined use of tissue-engineered implants embedded with staminal cells and growth factors. Many problems remain to be solved, however, before reliable applicability in humans. From a general point of view, stem cells obtained from various sources (e.g., adult bone marrow, umbilical cord) offer the same finalities as the embryonic stem cells, without the ethical obstacles related to the latter. Therefore, it may be that restoration of part or all of the articular surface of a joint will be possible by way of these mesenchymal progenitors that have the ability to differentiate into the chondrogenic and osteogenic lines, which is required for the restoration of the various layers of a normal articular cartilage and subchondral bone.

  2. Current Status of Engineering Education in America

    Barr, Ronald E.

    Many faculty believe that engineering education in America is at a crossroads and much change is needed. International competition in engineering and the global economy have major potential impact on the engineering workforce of the future. We must find ways to educate U.S. engineers to be competitive and creative contributors in the worldwide arena. Recent national reports are sounding the alarm that the U.S. is losing it leadership in technology and innovation, with consequences for economic prosperity and national security. The report Rising Above the Gathering Storm discusses this dilemma in detail and offers four recommendations to U.S. policymakers. The report Educating the Engineer of 2020 discusses new ways to prepare American engineers for the 21st Century. Furthermore, changes in ABET accreditation, along with new paradigms of teaching and new technology in the classroom, are changing the scholarship of engineering education. We must find ways to promote change in engineering faculty for this new opportunity in engineering educational scholarship. Future engineering students are now in K-12, which is becoming an increasingly diverse population that in the past has not been fully represented in engineering education. Current trends show disaffection for pursuing studies in science and engineering in the youth of our U.S. society. We must find new ways to portray engineering as an exciting and rewarding career, and certainly as an educational platform for professional careers beyond the baccalaureate degree.

  3. [Current status of noninvasive hemodynamics in hypertension].

    Science.gov (United States)

    Waisman, G

    Hypertension is a haemodynamic disorder resulting from a persistent mismatch between cardiac output and peripheral resistance. Hypertension undergoes haemodynamic progression during its natural history. Impedance cardiography is a method of evaluating the cardiovascular system that obtains haemodynamic information from beat to beat through the analysis of variations in the impedance of the thorax on the passage of an electric current. Impedance cardiography unmasks the haemodynamic deterioration underlying the increase in blood pressure as age and systolic blood pressure increases. This method may help to improve blood pressure control through individualized treatment with reduction of peripheral resistance, maintenance of cardiac output or its increase, improvement of arterial compliance and preservation of organ-tissue perfusion. It is useful in the management of patients with resistant hypertension, since a greater percentage of patients controlled with changes in the treatment in relation to the haemodynamic measurements are obtained. Impedance cardiography is important and has prognostic utility in relation to a haemodynamic deterioration pattern and increased cardiovascular events. Copyright © 2017 SEH-LELHA.

  7. International Shock-Wave Database: Current Status

    2013-06-01

    Shock-wave and related dynamic material response data serve for calibrating, validating, and improving material models over very broad regions of the pressure-temperature-density phase space. Since the middle of the 20th century vast amount of shock-wave experimental information has been obtained. To systemize it a number of compendiums of shock-wave data has been issued by LLNL, LANL (USA), CEA (France), IPCP and VNIIEF (Russia). In mid-90th the drawbacks of the paper handbooks became obvious, so the first version of the online shock-wave database appeared in 1997 (http://www.ficp.ac.ru/rusbank). It includes approximately 20000 experimental points on shock compression, adiabatic expansion, measurements of sound velocity behind the shock front and free-surface-velocity for more than 650 substances. This is still a useful tool for the shock-wave community, but it has a number of serious disadvantages which can't be easily eliminated: (i) very simple data format for points and references; (ii) minimalistic user interface for data addition; (iii) absence of history of changes; (iv) bad feedback from users. The new International Shock-Wave database (ISWdb) is intended to solve these and some other problems. The ISWdb project objectives are: (i) to develop a database on thermodynamic and mechanical properties of materials under conditions of shock-wave and other dynamic loadings, selected related quantities of interest, and the meta-data that describes the provenance of the measurements and material models; and (ii) to make this database available internationally through the Internet, in an interactive form. The development and operation of the ISWdb is guided by an advisory committee. The database will be installed on two mirrored web-servers, one in Russia and the other in USA (currently only one server is available). The database provides access to original experimental data on shock compression, non-shock dynamic loadings, isentropic expansion, measurements of sound

  8. Teledermatology. Current status and future directions.

    2001-01-01

    Teledermatology is becoming an increasingly common means of delivering dermatologic healthcare worldwide and will almost certainly play a greater role in the future. The type of technology used distinguishes the 2 modes of teledermatology consultation. The store and forward technique uses still digital images generated by a digital camera. Consultations of this type are considered asynchronous since the images are obtained, sent, and reviewed at different times. In contrast, real-time interactive consultations are synchronous. Patients and clinicians interact in real-time through an audio-video communication link. Each modality has its advantages and disadvantages, and studies appear in the literature that assess both technologies. Although diagnostic reliability (precision) assessments for teledermatology are subject to limitations, existing information indicates that both store and forward and real-time interactive technology result in reliable diagnostic outcomes when compared with clinic-based evaluations. Less information regarding diagnostic accuracy is available; however, one evaluation that used store and forward technology found comparable diagnostic accuracy between teledermatology consultations and clinic-based examinations. Currently, little information is available regarding cost effectiveness and patient outcomes. Existing evidence, while inconclusive, suggests that teledermatology may be more costly than traditional clinic-based care, especially when using real-time interactive technology. Teledermatology has been shown to have utility as a triage mechanism for determining the urgency or need for a clinic-based consultation. Overall, patients appear to accept teledermatology and are satisfied with it as a means of obtaining healthcare. Clinicians have also generally reported positive experiences with teledermatology. Future studies that focus on cost effectiveness, patient outcomes, and patient and clinician satisfaction will help further define the

    The recent biotechnology technique has been miniaturized and it features a fusion of electricity, electronics and mechanics in the existing biology. As an example, biochip is a collection of miniaturized test sites (microarrays) arranged on a solid substrate that permits many tests to be performed at the same time in order to achieve higher throughput and speed. Like a computer chip that can perform millions of mathematical operations in a second, the biochip can perform thousands of biological reactions, such as decoding genes, in a few seconds. The biochip is being used in toxicological, protein, and biochemical research and it can also be used to rapidly detect chemical agents used in biological warfare so that defensive measures can be taken. These biochip technologies incorporate elements of microfluidics, micromachining, synthetic chemistry, separation technologies, and detection technologies of biological molecules. Basically, biochips can be divided into two types: microarray and lab-on-a-chip system. Microarrays use planted probes to catch and identify target biological molecules while lab-on-a-chips actively process loaded samples. The biochips are becoming more diverse and customers are appearing all over the world. The products from the biochip market are being used to help accelerating the research processes and capabilities of bio-pharmaceutical drug discovery and basic academic bioresearch. To fully take advantages of the attributes of biochip technologies such as miniaturization, parallelism, automation and integration, there are some problems to overcome. The major problem is to reduce the cost. Currently the prices of biochip products are too expensive to replace traditional products and processes. As a method to solve the problem, a radioisotope can be used as a detecting sensor by appling on the biochip, as it were, radio-biochip that will further bring the cost down. The originality using the radioisotope on the biochip technology will be able

    2018-04-01

    Systemic treatment of metastatic renal cell carcinoma (mRCC) has substantially changed during the last 2 years due to approval of the immune-checkpoint inhibitor Nivolumab (Opdivo ® ) and new multikinase inhibitors (Cabozantinib, Lenvatinib, Tivozanib). The german kidney tumor guideline strongly recommends Nivolumab and Cabozantinib as 2nd line treatments after prior VEGF targeted therapy. CheckMate 025, the prospective randomized trial which led to approval of Nivolumab demonstrated improved overall survival (26 month vs. 19.7 month; hazard ratio 0.73; p = 0.0006) and response rate (26 % vs. 5 %) as well as a favorable toxicity profile compared with Everolimus. Currently, numerous combinations with PD-1/PD-L1 inhibitors are compared to Sunitinib as first line treatment of mRCC. Out of these CheckMate 214, a randomized phase-3 trial is the first to demonstrate a significant higher objective response rate (42 % vs. 27 %, p < 0.0001) and overall survival (Sunitinib 26.0 month, median for Nivo + Ipi has been not yet reached (28.2 - NR); Hazard ratio 0.63) for the combination of Nivolumab and the CTLA-4 antibody Ipilimumab in IMDC intermediate and high risk patients. Furthermore, CheckMate 214 shows better side effect profile and quality of life in patients receiving Nivolumab and Ipilimumab compared with Sunitinib. However, a considerable increase of immune related adverse events is associated with the immune combination therapy. Another randomized trial demonstrates improved progression-free survival for the combination of the PD-L1 inhibitor Atezolizumab and the VEGF antibody Bevacizumab in patients with PD-L1 positive tumors; this was found in all IMDC risk groups. Further phase-3 trials with "new" VEGFR-TKIs (Axitinib, Cabozantinib, Lenvatinib) and PD-1/PD-L1 inhibitor combinations are ongoing.In conclusion, the PD-1 immune checkpoint inhibitor Nivolumab will remain a standard treatment for patients with metastatic renal cell carcinoma

  12. Current status and future perspective of PET

    2002-01-01

    Positron Emission Tomography (PET) is a nuclear medicine imaging modality that consists of systemic administration to a subject of a radiopharmaceutical labeled with a positron-emitting radionuclide. Following administration, its distribution in the organ or structure under study can be assessed as a function of time and space by (1) detecting the annihilation radiation resulting from the interaction of the positrons with matter, and (2) reconstructing the distribution of the radioactivity from a series of that used in computed tomography (CT). The nuclides most generally exhibit chemical properties that render them particularly desirable in physiological studies. The radionuclides most widely used in PET are F-18, C-11, O-15 and N-13. Regarding to the number of the current PET Centers worldwide (based on ICP data), more than 300 PET Centers were in operation in 2000. The use of PET technology grew rapidly compared to that in 1992 and 1996, particularly in the USA, which demonstrates a three-fold rise in PET installations. In 2001, 194 PET Centers were operating in the USA. In 1994, two clinical and research-oriented PET Centers at Seoul National University Hospital and Samsung Medical Center, was established as the first dedicated PET and Cyclotron machines in Korea, followed by two more PET facilities at the Korea Cancer Center Hospital, Ajou Medical Center, Yonsei University Medical Center, National Cancer Center and established their PET Center. Catholic Medical School and Pusan National University Hospital have finalized a plan to install PET machine in 2002, which results in total of nine PET Centers in Korea. Considering annual trends of PET application in four major PET centers in Korea in Asan Medical Center recent six years (from 1995 to 2000), a total of 11,564 patients have been studied every year and the number of PET studies has shown steep growth year upon year. We had, 1,020 PET patients in 1995. This number increased to 1,196, 1,756, 2,379, 3

    It is estimated that at the current rate of growth the world's population will reach 8.5 billion by the year 2025 and 10-11 billion by the end of the 21st century. 90% of this population increase would occur in developing countries, where only 38% of couples used contraceptives during 1980-81 compared to 68% in developed countries. About 300 million couples in the Third World do not use contraceptives, although they do not want more children. Some of these contraceptives include natural steroids, such as progesterone and 17 beta-estradiol that is used for treatment of menopause (1-2 mg daily po). Medroxyprogesterone acetate and norethisterone enanthate depot injections have long-acting properties with low failure rates (3.6% + 0.7 pregnancies/100 women years) if given every 3 months, amenorrhea may occur. RU-486, substance with antiprogesterone activity, inhibits hormonal metabolism during ovulation in a dose of 100 mg/day, just like norgestimate. HRP 102 consists of 50 mg norethisterone enanthate and 5 mg estradiol valerate and cycloprovera contains 25 mg medroxyprogesterone acetate with 5 mg of estradiol cypionate. Both of these agents are effective contraceptives for 2 months. Norplant is implanted subcutaneously in capsule forms. It releases levonorgestrel/LNG for 6-7 years, and in a study of 992 women 2.6 pregnancies occurred for 100 women in the course of 5 years. Vaginal suppositories can release 20 mg/day LNG, or 5-10 mg progesterone/day, and they are considered ideal for nursing mothers. The IUD has been used by 60 million women, however, pelvic inflammatory disease may be associated with its use. Sulprostone and RU-486 (mifepristone) are post ovulatory agents with effectiveness of up to 90 day. Female sterilization has problems of reversibility, male sterilization is less accepted, and other male endocrine approaches producing azoospermia are in the testing phase.

    The HANARO (High-flux Advanced Neutron Application Research Reactor) is now operating at 24 MW to meet the user's demands in a variety of utilization fields. The most active field is the neutron scattering and diffraction using the currently available HRPD (High Resolution Powder Diffraction), FCD (Four Circle Diffraction), RSI (Residual Stress Instrument), and SANS (Small Angle Neutron Scattering). Using these instruments, we have been investigating such characteristics as materials' crystal structure and phase transition, residual stress, texture, and hard and soft matters. Through examination and inspection of the test specimens, NRF (Neutron Radiography Facility) is contributing to such fields as the nuclear industry, ordnance industry, aerospace industry, and archaeology. The second utilization field is the fuel and material irradiation test. KAERI (Korea Atomic Energy Research Institute) has developed atomized fuel powder and provided it to USA, France and Argentina. Under the RERTR program, KAERI has been contributing to the development of research reactor fuels of better quality. To test the reactor materials and fuels, instrumented and non-instrumented capsules are widely being used. To produce and supply RIs and pharmaceuticals for medical and industrial purposes, HANARO and its RIPF (Radioisotope Production Facility) has been fully complying with demands so that the national welfare might be enhanced by our efforts. NAA (Neutron Activation Analysis) is assisting the nuclear industry, environmental research and the promotion of the health area. To support all active utilizations, HANARO operators have been making every effort to not only improve the systems, if needed, but also to avoid the inadvertent reactor trip. Based upon this stable neutron supply, we have been developing and expanding the utilization fields and facilities. The PNS(Polarized Neutron Spectrometer) is under construction and the reflectometer is in preparation. The BNCT(Boron Neutron

    Full Text Available It is well known that the main parts of Solid Oxide Fuel Cells (SOFCs are build from ceramic materials. Namely the ceramic materials and composites, used for SOFCs manufacturing, are objects of the overview in the present work. The analysis carried out covers the last current publications in the field discussed. Special attention and examination in details have been done on patents state-of-the-art. After a background and short classification of the ceramic SOFCs materials the attention is focused on cathode, electrolyte, anode, interconnection and sealing materials. Their requirements, structure, thermal stability, composition control and behavior, processing and performance are the object of overview. A correlation has been made between the phase diagrams oxygen incorporation and transport, and SOFC advantages, generally for materials of lanthanum- base perovskite family. In order to analyze the innovative investigations regarding the patent branch of the SOFCs development and application, an object of review was patents from Japan, USA, Germany and European Union. Some examples of the inventions with accent on the ceramic materials are shown. In addition the tendency regarding R & D activities of SOFCs development materials from the leading companies in the world is analyzed.

    1986-01-01

    Recently available figures for 1982 and 1983 show that Catholic hospitals as a whole attained positive ratios of net income to fund balances and that these gains exceeded inflation in both years. The financial picture varies, however, when data for specific categories of Catholic hospitals are examined. For example, smaller hospitals relied more on borrowed funds to finance assets and generate profits, and for many of them these profits still did not exceed the 1983 inflation rate. Hospitals particularly vulnerable to diagnosis-related group payment--that is, teaching hospitals, hospitals with negative operating income, and hospitals adding beds--possessed less liquidity than Catholic hospitals aggregately. Hospitals in each of these categories experienced less-than-average basic profitability as well.

  17. Pre-diagnosis employment status and financial circumstances predict cancer-related financial stress and strain among breast and prostate cancer survivors.

    Sharp, Linda; Timmons, Aileen

    2016-02-01

    Cancer may have a significant financial impact on patients, but the characteristics that predispose patients to cancer-related financial hardship are poorly understood. We investigated factors associated with cancer-related financial stress and strain in breast and prostate cancer survivors in Ireland, which has a complex mixed public-private healthcare system. Postal questionnaires were distributed to 1373 people diagnosed with cancer 3-24 months previously identified from the National Cancer Registry Ireland. Outcomes were cancer-related financial stress (impact of cancer diagnosis on household ability to make ends meet) and financial strain (concerns about household financial situation since cancer diagnosis). Modified Poisson regression was used to estimate relative risks (RR) for factors associated with cancer-related financial stress and strain. Seven hundred forty survivors participated (response rate = 54 %). Of the respondents, 48 % reported cancer-related financial stress and 32 % cancer-related financial strain. Compared to those employed at diagnosis, risk of cancer-related financial stress was significantly lower in those not working (RR = 0.71, 95 % CI 0.58-0.86) or retired (RR = 0.48, 95 % CI 0.34-0.68). It was significantly higher in those who had dependents; experienced financial stress pre-diagnosis; had a mortgage/personal loans; had higher direct medical out-of-pocket costs; and had increased household bills post-diagnosis. For cancer-related financial strain, significant associations were found with dependents, pre-diagnosis employment status and pre-diagnosis financial stress; risk was lower in those with higher direct medical out-of-pocket costs. Cancer-related financial stress and strain are common. Pre-diagnosis employment status and financial circumstances are important predictors of post-diagnosis financial wellbeing. These findings could inform development of tools to identify patients/survivors most in need of financial

  18. The impact of financial globalization and financialization on the economy in the current crisis through banking corporate governance

    Juan Antonio Azkunaga

    2013-10-01

    Full Text Available This work analyzes the role of governance of financial entities in the current crisis. Neoliberal economic policies, deregulation and liberalization have characterized financial globalization, giving rise to the financialization of the economy. This paper, using the analysis-synthesis method, shows that the corporate governance of entities has adapted to the new social environment under the influence of the interests of the investors. The results of this paper suggest the need to monitor the over-emphasis on the maximization of short-term shareholder value without relativizing the risk taken to achieve it, as such, the emphasis on short-term shareholder value is considered a crucial contributing factor to the present crisis.

    2005-01-01

    Most resident physicians accrue significant financial debt throughout their medical and graduate medical education. The objective of this study was to analyze emergency medicine resident debt status, financial planning actions, and educational experiences for financial planning and debt management. A 22-item questionnaire was sent to all 123 Accreditation Council on Graduate Medical Education-accredited emergency medicine residency programs in July 2001. Two follow-up mailings were made to increase the response rate. The survey addressed four areas of resident debt and financial planning: 1) accrued debt, 2) moonlighting activity, 3) financial planning/debt management education, and 4) financial planning actions. Descriptive statistics were used to analyze the data. Survey responses were obtained from 67.4% (1,707/2,532) of emergency medicine residents in 89 of 123 (72.4%) residency programs. Nearly one half (768/1,707) of respondents have accrued more than 100,000 dollars of debt. Fifty-eight percent (990/1,707) of all residents reported that moonlighting would be necessary to meet their financial needs, and more than 33% (640/1,707) presently moonlight to supplement their income. Nearly one half (832/1,707) of residents actively invested money, of which online trading was the most common method (23.3%). Most residents reported that they received no debt management education during residency (82.1%) or medical school (63.7%). Furthermore, 79.1% (1,351/1,707) of residents reported that they received no financial planning lectures during residency, although 84.2% (1,438/1,707) reported that debt management and financial planning education should be available during residency. Most emergency medicine residency programs do not provide their residents with financial planning education. Most residents have accrued significant debt and believe that more financial planning and debt management education is needed during residency.

    Full Text Available Efficient current assets management should provide optimum level of company’s net current assets as interrelation between current assets and short-term liabilities. The companies whose short-term liabilities are not proportionate to cashable current assets face the problem of insolvency and all negative consequences caused by insolvency. Rate of return to total assets measures how good is the management’s use of the company property for the purpose of creating operating profit, regardless of the fact how these assets are financed. Serbian economy is burdened by insolvency and significant indebtedness under unfavorable loan terms, so adequate attention has to be dedicated to the matters of the structure of operating property and its financing in order to improve competitiveness and efficiency of business.

    Full Text Available Non-financial reporting forms part of corporate reporting. Among other, it includes disclosure of information regarding corporate social responsibility (CSR/sustainability issues and as such represent the supplement to the information provided by financial statements. Compared to the financial reporting, non-financial reporting is voluntary in majority of countries, including Croatia. Thus, companies decide on their own whether to disclose on this issue or not. Considering its voluntariness, the aim of this paper is to determine the current state of non-financial reporting in Croatia by identifying the financial characteristics of companies disclosing non-financial reports. In data analysis, the logistic regression was used. The research was conducted on a sample of Croatian publicly listed companies. Obtained results indicate that larger, more profitable and efficient companies are more probable to disclose non-financial reports, while indebtedness is not significant for it. In addition, further development of corporate social accounting is required, as well as promotion of non-financial reporting benefits.

    2008-03-21

    At the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair. A short questionnaire was circulated amongst the membership and interested parties. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice.

  8. FISCAL POLICY AND ECONOMIC DEVELOPMENT IN THE CURRENT FINANCIAL CRISIS

    Directory of Open Access Journals (Sweden)

    VALENTIN SAVA

    2012-05-01

    Full Text Available Fiscal policies in the current era are the sovereign right of states to collect and administer taxes on national territory. In this respect, the European Union, which is an association of independent states, did not created an European tax - although many politicians proposing it - and within the Union is found important differences between the tax systems of member states. Due to historical and national different traditions, the EU member states have heterogeneous tax systems and revenue sharing systems because of different conceptions of public policies relative to the role of state in social and economic respective community’s life. The financing of public spending is usually considered the main function of taxation. In the original tradition following Locke1, property protection is the main functions of the state. As a result, the tax must correspond to the services rendered, that is to say, to pay the State for the protection of the rights it provides. Here we are at the origin of the doctrine of the benefit that there should be equivalence between the utility derived by the citizens of public services they consume and the "price" they pay tax.

    Full Text Available Abstract. Any management decision has a direct monetary impact on the structure uses and sources of cash. Cash Management aims to permanently maintain a balance between inflows and outflows of cash and cash to predict the impact of any operational decisions that could affect these flows. The success of any business requires good management of all these flows. The principle of this approach is relatively simple: using a minimum of ores to obtain maximum performance in a given period. Cash management is an extremely complex issue, and balancing receipts and payments flow is a constant struggle for survival of firms. In It work we will focus on how they are oriented in a going concern basis, cash inflows and financing needs of current operations. Managers should understand and know the specific movements of cash within the business system, driven daily decisions on operating, investing or financing, and a variety of external circumstances which affect the company. Such decisions and events can affect the company's ability to pay its obligations to obtain credit from suppliers, banks or credit institutions and to maintain an operational level in line with the company's products and services through investments.

    Hepatic encephalopathy is a spectrum of neurocognitive manifestations often seen in patients with liver injury or rarely in patients with portosystemic shunting without liver injury. It can be divided into minimal (covert) hepatic encephalopathy and overt hepatic encephalopathy, depending on the severity. Patients with hepatic encephalopathy have compromised clinical outcomes, decreased quality of life, and increased healthcare utilization, often resulting in a heavy financial and personal burden on caregivers. The diagnosis remains largely clinical, with the exclusion of possible other causes for the altered mental status. Current treatment strategies include nonabsorbable disaccharides and antibiotics. This review will focus on the diagnosis, management and clinical impact of hepatic encephalopathy. PMID:27377741

    2009-12-01

    Full Text Available The article deals with the analysis of the current situation on the global financial arena, analyzing the chain of cause and effect of the origins of the economic crisis and providing its possible logical outcomes. We are trying to prove here that the way the world economic situation develops will lead to either further growth or stagnation of national economies and define their position in the global business, financial, and social spheres.

    We provide an analysis of the serious transformations financial economics have been undergoing at the end of the 20th and beginning of the 21st centuries. All these changes, such as the development of international fusions on financial markets, the creation of new financial instruments, products and services, and others, have been caused largely by (and also have led to significant events in the global political arena. However, regardless of the transformations, world leadership remains in the hands of US government and business and that of their closest partners, while those societies that are not willing to support the “Americanized” world order end up on the blacklist of the World Bank, the IMF, and other international financial institutions.

    Finally, the article provides our views of the possible ways of dealing with the global economic stagnation. We highlight the importance of the strong and careful supervision of any global as well as national financial activities, the education of the public on the issues of wise investments, and the dangers of living on credit.

    Economic abuse is a form of domestic violence that has a significant impact on the health and financial wellbeing of victims, but is understudied. This study determined the lifetime prevalence of economic abuse in Australia by age and gender, and the associated risk factors. The 2012 ABS Personal Safety Survey was used, involving a cross-sectional population survey of 17,050 randomly selected adults using face-to-face interviews. The survey-weighted prevalence of economic abuse was calculated and analysed by age and gender. Logistic regression was used to adjust odds ratios for possible confounding between variables. The lifetime prevalence of economic abuse in the whole sample was 11.5%. Women in all age groups were more likely to experience economic abuse (15.7%) compared to men (7.1%). Disability, health and financial stress status were significant markers of economic abuse. For women, financial stress and disability were important markers of economic abuse. However, prevalence rates were influenced by the measures used and victims' awareness of the abuse, which presents a challenge for screening and monitoring. Implications for public health: Social, health and financial services need to be aware of and screen for the warning signs of this largely hidden form of domestic violence. © 2017 The Authors.

    This paper is the result of the work of a SCENET (The European Network for Superconductivity) material working group's efforts on giving values for present and future expected performance of high-temperature superconducting (HTS) wires and tapes. The purpose of the work is to give input to the design of HTS applications like power cables, motors, current leads, magnets, transformers and generators. The current status performance values are supposed to be used in the design of today's prototypes and the future values for the design of fully commercial HTS applications of the future. We focus on what is expected to be the relevant parameters for HTS application design. The most successful technique by far for making HTS tapes has been on the (Bi, Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x} (Bi-2223) material by the powder-in-tube (PIT) technique and this paper therefore focuses on giving the current status and expected future performance for Bi-2223 tapes.

    The effect of income status on patient outcome merits investigation during periods of financial crisis. We evaluated the impact of income status on out-of-hospital prognosis in a cohort of acute coronary syndrome (ACS) patients, included in a countrywide study during a period of financial crisis. The study is a secondary analysis of a prospective, multicenter, observational study-the PHAETHON study-enrolling consecutive ACS patients in 37 hospitals in Greece. Patients were classified as low or high income based on the reported net annual household income using as a cut-off point the relative poverty threshold for Greece of 12,000 Euros. The outcome measure was survival free of the primary composite endpoint (cardiovascular death, myocardial infarction, stroke/transient ischemic attack, urgent revascularization and urgent hospitalization due to cardiovascular causes). The study population included 794 patients. The administration rate of evidence-based medications was similar in the low- (n = 455) and high-income (n = 339) groups during hospitalization and upon discharge. In a median follow-up of 189 days (interquartile range: 180-212 days), low-income patients had 92 % higher risk of the combined endpoint as compared to high-income patients [Hazard ratio (HR):1.92, 95 % CI:1.25-2.94, p = 0.003]. The effect of low-income status on the combined outcome remained significant after adjustment for age, gender and depression (HR:1.59, 95 % CI:1.02-2.49; p = 0.043). In a period of financial crisis, low income is a significant and independent predictor of poor out-of-hospital outcome in ACS patients. This association has profound implications and should be taken into consideration by public health policy makers.

    Computed tomography myocardial perfusion (CTP) combined with coronary computed tomography angiography (CCTA) may constitute a "1-stop shop" for the noninvasive diagnosis of hemodynamically significant coronary stenosis during a single CT examination. CTP shows high diagnostic performance and provides incremental value over CCTA for the detection of hemodynamically significant coronary stenosis in patients with a high Agatston calcium score or coronary artery stents. Future studies should determine the optimal protocol and clinical value of CTP for guiding revascularization strategy and prognostication. In this article, we review the current status and future perspectives of CTP, focusing on technical considerations, clinical applications, and future research topics.

    Recent guidelines have encouraged gastroenterology and surgical training programs to integrate simulation into their core endoscopic curricula. However, the role that simulation currently has within training programs is unknown. This study aims to assess the current status of simulation among gastroenterology fellowship programs. This questionnaire study consisted of 38 fields divided into two sections. The first section queried program directors' experience on simulation and assessed the current status of simulation at their institution. The second portion surveyed their opinion on the potential role of simulation on the training curriculum. The study was conducted at the 2013 American Gastroenterological Association Training Directors' Workshop in Phoenix, Arizona. The participants were program directors from Accreditation Council for Graduate Medical Education accredited gastroenterology training programs, who attended the workshop. The questionnaire was returned by 69 of 97 program directors (response rate of 71%). 42% of programs had an endoscopic simulator. Computerized simulators (61.5%) were the most common, followed by mechanical (30.8%) and animal tissue (7.7%) simulators, respectively. Eleven programs (15%) required fellows to use simulation prior to clinical cases. Only one program has a minimum number of hours fellows have to participate in simulation training. Current simulators are deemed as easy to use (76%) and good educational tools (65%). Problems are cost (72%) and accessibility (69%). The majority of program directors believe that there is a need for endoscopic simulator training, with only 8% disagreeing. Additionally, a majority believe there is a role for simulation prior to initiation of clinical cases with 15% disagreeing. Gastroenterology fellowship program directors widely recognize the importance of simulation. Nevertheless, simulation is used by only 42% of programs and only 15% of programs require that trainees use simulation prior to

    This study examines the effects of economic loss on the life satisfaction and mental health of Wenchuan earthquake survivors. Economic loss is measured by earthquake impacts on the income and houses of the survivors. The correlation analysis shows that earthquake impact on income is significantly correlated with life satisfaction and depression. The regression analyses indicate that earthquake impact on income is indirectly associated with life satisfaction and depression through its effect on financial strain. The research highlights the importance of coping strategies in maintaining a balance between economic status and living demands for disaster survivors. © 2015 The Author(s).

    The Uranium Epidemiology Study at the University of New Mexico was initiated in 1977 with the objective of assessing health effects of uranium mining in the Grants, New Mexico, area. The planned approach was a cohort study of mortality that would capitalize on the availability of health records at the Grants Clinic. The first year's work confirmed the study's feasibility (Buechley, 1979). Subsequent efforts have focused on the health and exposure data base and comprehensive follow-up. A retrospective cohort study of early miners is in progress; a prospective cohort study of miners who began working under the current federal standard is planned. This report will summarize the current status of the Uranium Epidemiology Study

    1999-01-01

    The current status of elementary particle physics can be briefly summarized as follows: the Standard Model of elementary particles is perfectly (at the level of radiation effects!) adequate in describing all the available experimental data except for the recent indications of neutrino oscillations. At the same time, much (and possibly most) of today's cosmology is not encompassed by the Standard Model - a fact which, together with intrinsic theoretical difficulties and the neutrino oscillation challenge, strongly indicates that the Standard Model is incomplete. It is expected that in the current decade a 'new physics', i.e. particles and interactions beyond the Standard Model, will emerge. Major advances in cosmology, both in terms of qualitatively improved observations and theoretical analysis of the structure and evolution of the Universe, are expected as well. (special issue)

    2015-01-01

    Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed. PMID:24389146

    Objective: To determine the current status of research experience in psychiatry residency programs across Canada. Method: Coordinators of Psychiatric Education (COPE) resident representatives from all 17 psychiatry residency programs in Canada were asked to complete a survey regarding research training requirements in their programs. Results: Among the 17 COPE representatives, 15 completed the survey, representing 88% of the Canadian medical schools that have a psychiatry residency program. Among the 15 programs, 11 (73%) require residents to conduct a scholarly activity to complete residency. Some of these programs incorporated such a requirement in the past 5 years. Ten respondents (67%) reported availability of official policy and (or) guidelines on resident research requirements. Among the 11 programs that have a research requirement, 10 (91%) require residents to complete 1 scholarly activity; 1 requires completion of 2 scholarly activities. Eight (53%) residency programs reported having a separate research track. All of the programs have a research coordinator and 14 (93%) programs provide protected time to residents for conducting research. The 3 most common types of scholarly activities that qualify for the mandatory research requirement are a full independent project (10 programs), a quality improvement project (8 programs), and assisting in a faculty project (8 programs). Six programs expect their residents to present their final work in a departmental forum. None of the residency programs require publication of residents’ final work. Conclusions: The current status of the research experience during psychiatry residency in Canada is encouraging but there is heterogeneity across the programs. PMID:25565474

    2014-11-01

    Full Text Available A review of national and international publications on paragonimiasis in Ecuador, epidemiological records from the Ministry of Public Health and unpublished research data was conducted to summarise the current status of the parasite/disease. The purpose of the review is to educate physicians, policy-makers and health providers on the status of the disease and to stimulate scientific investigators to conduct further research. Paragonimiasis was first diagnosed in Ecuador 94 years ago and it is endemic to both tropical and subtropical regions in 19 of 24 provinces in the Pacific Coast and Amazon regions. Paragonimus mexicanus is the only known species in the country, with the mollusc Aroapyrgus colombiensis and the crabs Moreirocarcinus emarginatus, Hypolobocera chilensis and Hypolobocera aequatorialis being the primary and secondary intermediate hosts, respectively. Recent studies found P. mexicanus metacercariae in Trichodactylus faxoni crabs of the northern Amazon. Chronic pulmonary paragonimiasis is commonly misdiagnosed and treated as tuberculosis and although studies have demonstrated the efficacy of praziquantel and triclabendazole for the treatment of human infections, neither drug is available in Ecuador. Official data recorded from 1978-2007 indicate an annual incidence of 85.5 cases throughout the 19 provinces, with an estimated 17.2% of the population at risk of infection. There are no current data on the incidence/prevalence of infection, nor is there a national control programme.

  3. Parametric overdispersed frailty models for current status data.

    2017-12-01

    Frailty models have a prominent place in survival analysis to model univariate and multivariate time-to-event data, often complicated by the presence of different types of censoring. In recent years, frailty modeling gained popularity in infectious disease epidemiology to quantify unobserved heterogeneity using Type I interval-censored serological data or current status data. In a multivariate setting, frailty models prove useful to assess the association between infection times related to multiple distinct infections acquired by the same individual. In addition to dependence among individual infection times, overdispersion can arise when the observed variability in the data exceeds the one implied by the model. In this article, we discuss parametric overdispersed frailty models for time-to-event data under Type I interval-censoring, building upon the work by Molenberghs et al. (2010) and Hens et al. (2009). The proposed methodology is illustrated using bivariate serological data on hepatitis A and B from Flanders, Belgium anno 1993-1994. Furthermore, the relationship between individual heterogeneity and overdispersion at a stratum-specific level is studied through simulations. Although it is important to account for overdispersion, one should be cautious when modeling both individual heterogeneity and overdispersion based on current status data as model selection is hampered by the loss of information due to censoring. © 2017, The International Biometric Society.

    There is increasing patient and surgeon interest in robotic-assisted surgery, particularly with the proliferation of da Vinci surgical systems (Intuitive Surgical, Sunnyvale, CA, USA) throughout the world. There is much debate over the usefulness and cost-effectiveness of these systems. The currently available robotic surgical technology is described. Published data relating to the da Vinci system are reviewed and the current status of surgical robotics within Australia and New Zealand is assessed. The first da Vinci system in Australia and New Zealand was installed in 2003. Four systems had been installed by 2006 and seven systems are currently in use. Most of these are based in private hospitals. Technical advantages of this system include 3-D vision, enhanced dexterity and improved ergonomics when compared with standard laparoscopic surgery. Most procedures currently carried out are urological, with cardiac, gynaecological and general surgeons also using this system. The number of patients undergoing robotic-assisted surgery in Australia and New Zealand has increased fivefold in the past 4 years. The most common procedure carried out is robotic-assisted laparoscopic radical prostatectomy. Published data suggest that robotic-assisted surgery is feasible and safe although the installation and recurring costs remain high. There is increasing acceptance of robotic-assisted surgery, especially for urological procedures. The da Vinci surgical system is becoming more widely available in Australia and New Zealand. Other surgical specialties will probably use this technology. Significant costs are associated with robotic technology and it is not yet widely available to public patients.

    The European Commission pursues the environmental and energy policy goals of limiting global warming to a maximum of 2 C and, therefore, reducing CO 2 emissions by at least 20%. Nuclear power, with its present 30% contribution to the Community's electricity supply and the low CO 2 emissions of the entire fuel cycle, makes an important contribution to an energy mix matching the 3 factors of competitiveness, security of supply, and sustainability. The decision to use nuclear power plants in their respective countries for electricity production is left to each member state. As of mid-2008, 146 nuclear power plants were in operation in the European Union, while 74 had been shut down permanently. Two nuclear power plants had been demolished completely, showing that the European Community is just at the beginning of the learning curve in this field. The importance of nuclear power plant decommissioning and demolition will increase in the future as replacement capacity in nuclear power generation will become necessary. The European Commission's activities in decommissioning and demolition date from the 1990s: The provisions about environmental impact assessment and the recommendations to apply Article 37 (potential impacts on water, soil and air) of the Euratom Treaty demand a description of decommissioning and demolition of nuclear power plants. In a ruling of 2002, the European Court of Justice assigns to the Community the required competences in the fields of nuclear safety and, consequently, also decommissioning and demolition. The financial provisions necessary for these activities are covered in the Electricity Directive within the framework of the rules for a common single market in 2003. After a first status report, the Commission published recommendations about financing decommissioning and demolition in 2006. (orig.)

  6. Australian shellfish ecosystems: Past distribution, current status and future direction.

    Full Text Available We review the status of marine shellfish ecosystems formed primarily by bivalves in Australia, including: identifying ecosystem-forming species, assessing their historical and current extent, causes for decline and past and present management. Fourteen species of bivalves were identified as developing complex, three-dimensional reef or bed ecosystems in intertidal and subtidal areas across tropical, subtropical and temperate Australia. A dramatic decline in the extent and condition of Australia's two most common shellfish ecosystems, developed by Saccostrea glomerata and Ostrea angasi oysters, occurred during the mid-1800s to early 1900s in concurrence with extensive harvesting for food and lime production, ecosystem modification, disease outbreaks and a decline in water quality. Out of 118 historical locations containing O. angasi-developed ecosystems, only one location still contains the ecosystem whilst only six locations are known to still contain S. glomerata-developed ecosystems out of 60 historical locations. Ecosystems developed by the introduced oyster Crasostrea gigas are likely to be increasing in extent, whilst data on the remaining 11 ecosystem-forming species are limited, preventing a detailed assessment of their current ecosystem-forming status. Our analysis identifies that current knowledge on extent, physical characteristics, biodiversity and ecosystem services of Australian shellfish ecosystems is extremely limited. Despite the limited information on shellfish ecosystems, a number of restoration projects have recently been initiated across Australia and we propose a number of existing government policies and conservation mechanisms, if enacted, would readily serve to support the future conservation and recovery of Australia's shellfish ecosystems.

    Extensive efforts have been made in both academia and industry in the research and development of smart wearable systems (SWS) for health monitoring (HM). Primarily influenced by skyrocketing healthcare costs and supported by recent technological advances in micro- and nanotechnologies, miniaturisation of sensors, and smart fabrics, the continuous advances in SWS will progressively change the landscape of healthcare by allowing individual management and continuous monitoring of a patient's health status. Consisting of various components and devices, ranging from sensors and actuators to multimedia devices, these systems support complex healthcare applications and enable low-cost wearable, non-invasive alternatives for continuous 24-h monitoring of health, activity, mobility, and mental status, both indoors and outdoors. Our objective has been to examine the current research in wearable to serve as references for researchers and provide perspectives for future research. Herein, we review the current research and development of and the challenges facing SWS for HM, focusing on multi-parameter physiological sensor systems and activity and mobility measurement system designs that reliably measure mobility or vital signs and integrate real-time decision support processing for disease prevention, symptom detection, and diagnosis. For this literature review, we have chosen specific selection criteria to include papers in which wearable systems or devices are covered. We describe the state of the art in SWS and provide a survey of recent implementations of wearable health-care systems. We describe current issues, challenges, and prospects of SWS. We conclude by identifying the future challenges facing SWS for HM. Copyright © 2012 Elsevier B.V. All rights reserved.

  10. Nuclear power for sustainable development. Current status and future prospects

    International Nuclear Information System (INIS)

    Adamantiades, A.; Kessides, I.

    2009-01-01

    Interest in nuclear power has been revived as a result of volatile fossil fuel prices, concerns about the security of energy supplies, and global climate change. This paper describes the current status and future plans for expansion of nuclear power, the advances in nuclear reactor technology, and their impacts on the associated risks and performance of nuclear power. Advanced nuclear reactors have been designed to be simpler and safer, and to have lower costs than currently operating reactors. By addressing many of the public health and safety risks that plagued the industry since the accidents at Three Mile Island and Chernobyl, these reactors may help break the current deadlock over nuclear power. In that case, nuclear power could make a significant contribution towards reducing greenhouse gas emissions. However, significant issues persist, fueling reservations among the public and many decision makers. Nuclear safety, disposal of radioactive wastes, and proliferation of nuclear explosives need to be addressed in an effective and credible way if the necessary public support is to be obtained.

    The treatment of gliomas is highly individualized. Surgery for gliomas is essentially for histological diagnosis, to alleviate mass effect, and most importantly, to favor longer survival expectancy. During the past two decades, many surgical techniques and adjuvants have been applied to glioma surgery in China, which lead to a rapid development in the field of cerebral glioma surgery. This article broadly and critically reviewed the existing studies on cerebral glioma surgery and to portrait the current status of glioma surgery in China. A literature search was conducted covering major innovative surgical techniques and adjuvants for glioma surgery in China. The following databases were searched: the Pubmed (January 1995 to date); China Knowledge Resource Integrated Database (January 1995 to date) and VIP Database for Chinese Technical Periodicals (January 1995 to date). A selection criterion was established to exclude duplicates and irrelevant studies. The outcome measures were extracted from included studies. A total of 3307 articles were initially searched. After excluded by abstracts and full texts, 69 studies conducted in the mainland of China were included and went through further analysis. The philosophy of surgical strategies for cerebral gliomas in China is undergoing tremendous change. Nowadays Chinese neurosurgeons pay more attention to the postoperative neurofunctional status of the patients. The aim of the glioma surgery is not only the more extensive tumor resection but also the maximal safety of intervention. The well balance of longer overall survival and higher quality of life should be judged with respect to each individual patient.

  12. Current Diagnosis, Treatment and Etiology of Status Epilepticus

    2014-03-01

    Full Text Available Status Epilepticus (SE is a medical emergency that causes significant morbidity and mortality and requires prompt diagnosis and treatment. Although SE can be divided into two subgroups as convulsive and nonconvulsive, treatment principles are generally similar. Treatment should be prompt and underlying cause should be corrected. Although intravenous lorazepam is the first-line treatment due to a lower risk of relapse, diazepam becomes the first choice since loeazepan is not available in our country. Even though intravenous benzodiazepine stops seizures, intravenous antiepileptic drug (phenytoin, etc. should be administered at a loading dose. Patients with refractory status epilepticus should be supported with respect to vital, respiratory, metabolic and hemodynamic aspects and followed up in an intensive care unit to monitor cerebral electrical activity. The most common cause in the etiology is the cessation of antiepileptic drugs. The aim of SE treatment is to stop seizures and prevent complications and recurrence. In this paper, current diagnosis, treatment and etiology of SE are reviewed.

    2012-12-01

    Full Text Available The article argues that the current financial crisis that began unfolding in late 2007 cannot be explained merely by institutional failure, false economic theories, or human misbehavior. Instead, the crisis must be analyzed against the backdrop of the internal contradictions of capitalist accumulation and the gradual disintegration of the post-war hegemonic world order under U.S. leadership. The specifics of the crisis are inherently related to the failure of Fordism in the 1970s and the emergence of a post-Fordist, neoliberal, and finance-driven regime of accumulation that was pushed to its limits in the lead-up to the current downturn.

    Full Text Available Heart failure is a major public health problem and its management requires a significant amount of health care resources. Even with administration of the best available medical treatment, the mortality associated with the disease remains high. As therapeutical strategies for heart failure have been refined, the number of patients suffering from the disease has expanded dramatically. Although heart transplantation still represents the gold standard therapeutical approach, the implantation of mechanical circulatory support devices (MCSDs evolved to a well-established management for this disease. The limited applicability of heart transplantation caused by a shortage of donor organs and the concurrent expand of the patient population with end-stage heart failure led to a considerable utilization of MCSDs. This paper outlines the current status of mechanical circulatory support.

    The current status of the domestic manufacturing and sales markets of Anoectochilus roxburghii were investigated and analyzed in the study. Some problems in the A. roxburghii industry were revealed and a variety of sustainable development countermeasures were also proposed. The main problems of A. roxburghii industry are the lack of protection for wild resources, the lag in the speed of variety breeding, the insufficient research on the quality systems, the low level of industry and product innovation capability, as well as the relatively low market cognition and brand competence. Therefore, strengthening the protection for breeding resources, establishing a dynamic monitoring system, promoting the variety breeding, constructing a propagation system for improved varieties, enhancing the quality of medicinal herbs, accelerating the adjustment of product structure, upgrading the industry technology, strengthening brand competence and expanding the market, will be the effective methods to realize the sustainable development of A. roxburghii industry.

    The usefulness of thermoluminescence (TL) in geological studies is being increasingly recognized, as may be judged from the considerable volume of literature accumulated over the past couple of decades; besides, a number of seminars, conferences and specialists' meetings have also been held on the subject of applied TL. However, these publications lie scattered over several periodicals and conference proceedings and an interested worker finds it difficult to obtain the gist of the contributions in one place. The present authors felt a need for this and have, therefore, attempted to bring together in this Report the current status of TL research about different minerals; applications in the fields of geochronology, ore-prospecting, stratigraphic correlation, geothermometry and other useful areas are also included.

    A research is performed: to define wake non-encounter & hazard, to provide requirements for sensors, and to obtain input from the user community. This research includes: validating wake encounter simulation models, establishing a metric to quantify the upset potential of a wake encounter, applying hazard metric and simulation models to the commercial fleet for development of candidate acceptable encounter limits, and applying technology to near term problems to evaluate current status of technology. The following lessons are learned from this project: technology is not adequate to determine absolute spacing requirements; time, not distance, determines the duration of the wake hazard; Optimum standards depend on the traffic; Wing span is an important parameter for characterizing both generator and follower; and Short span "biz jets" are easily rolled.

    It is the current status of QA and our QA experiences with nuclear power plants against the background of the Japanese social and business environment. Accordingly, in 1972, 'The Guidance for Quality Assurance in Construction of Nuclear Power Plants' based on U. S. 10CEF50 Appendix B, was published by the Japan Electric Association. 'Jug-4101 The Guide for Quality Assurance of Nuclear Power Plants' has been prepared by referring to the IAEA QA code. The Guide has been accepted by the Japanese nuclear industry and applied to the QA programs of every organization concerned therewith. The Japanese approach to higher quality will naturally be different from that of other countries because of Japan's cultural, social, and economic conditions. Even higher quality is being aimed at through the LWR Improvement and Standardization Program and coordinated quality assurance efforts

    Full Text Available Abstract Gas Shielded Tungsten Arc Welding (GTAW – a process well-known providing highest quality weld results joined though by lower performance. Gas Metal Arc Welding (GMAW is frequently chosen to increase productivity along with broadly accepted quality. Those industry segments, especially required to produce high quality corrosion resistant weld surfacing e.g. applying nickel base filler materials, are regularly in consistent demand to comply with "zero defect" criteria. In this conjunction weld performance limitations are overcome employing advanced 'hot-wire' GTAW systems. This paper, from a Welding Automation perspective, describes the technology of such devices and deals with the current status is this field – namely the application of dual-cathode hot-wire electrode GTAW cladding; considerably broadening achievable limits.

    The Dortmund Low Background Facility (DLB) is a low-background gamma ray spectrometry system with an artificial overburden. The overburden of ten meters of water equivalent, in combination with a multi-layer lead castle and an active muon veto are shielding a high-purity germanium detector of 60 % relative efficiency. The background level is remarkably low compared to a conventional spectrometer system without special shielding and enables sensitivities well below 1 Bq/kg. Thus, material screening measurements as well as environmental monitoring measurements are possible on an easy-accessible location above ground at the campus of the Technische Universitaet Dortmund. The integral background count rate between 40 keV and 2700 keV is 2.528±0.004 counts/kg/min, which is comparable to systems that are situated below ground. In the talk, an overview of the current status of the DLB is given and recent developments are presented.

    2005-01-01

    Dentists belong to a professional group potentially exposed to harmful biological factors which most often are infectious microorganisms, less frequently - allergenic or toxic microorganisms. The fundamental routes of spreading harmful microorganisms in a dental surgery are: blood-borne, saliva-droplet, direct contact with a patient and with infected equipment, and water-droplet infections. In this paper, the current status of knowledge on microbiological hazards in a dentist's work is presented. Groups of microorganisms, such as prions, viruses, bacteria, fungi and protozoa, to which a dentist is, or may be exposed, are discussed. Epidemiological assessment of microbiological hazards in a dentist's work was performed and the basic principles of prevention formulated. Special attention was given to microflora in dental unit waterlines, and the biofilm persisting in them, as a source of occupational hazards specific for a dentist's workplace.

    The general status of the materials research and development activities currently under way in support of controlled thermonuclear fusion reactors in the United States is reviewed. In the area of magnetic confinement configurations, attention is given to development programs for first wall materials, which are at various stages for possible austenitic stainless steels, high-strength Fe-Ni-Cr alloys, reactive and refractory metal alloys, specially designed long-range ordered and rapidly solidified alloys, and ferritic/martensitic steels, and for tritium breeding materials, electrical insulators, ceramics, and coolants. The development of materials for inertial confinement reactors is also surveyed in relation to the protection scheme employed for the first wall and the effects of pulsed neutron irradiation. Finally, the materials requirements and selection procedures for the ETF/INTOR and Starfire tokamak reactor designs are examined. Needs for the expansion of research on nonfirst-wall materials and inertial confinement fusion reactor material requirements are pointed out

    Current status of design code of accelerator (NMTC/JAERI code), outline of physical model and evaluation of accuracy of code were reported. To evaluate the nuclear performance of accelerator and strong spallation neutron origin, the nuclear reaction between high energy proton and target nuclide and behaviors of various produced particles are necessary. The nuclear design of spallation neutron system used a calculation code system connected the high energy nucleon{center_dot}meson transport code and the neutron{center_dot}photon transport code. NMTC/JAERI is described by the particle evaporation process under consideration of competition reaction of intranuclear cascade and fission process. Particle transport calculation was carried out for proton, neutron, {pi}- and {mu}-meson. To verify and improve accuracy of high energy nucleon-meson transport code, data of spallation and spallation neutron fragment by the integral experiment were collected. (S.Y.)

    International Nuclear Information System (INIS)

    Rourke, Fergal O.; Boyle, Fergal; Reynolds, Anthony

    2010-01-01

    There is a growing demand for the use of renewable energy technologies to generate electricity due to concerns over climate change. The oceans provide a huge potential resource of energy. Energy extraction using marine current energy devices (MCEDs) offers a sustainable alternative to conventional sources and a predictable alternative to other renewable energy technologies. A MCED utilises the kinetic energy of the tides as opposed to the potential energy which is utilised by a tidal barrage. Over the past decade MCEDs have become an increasingly popular method of energy extraction. However, marine current energy technology is still not economically viable on a large scale due to its current stage of development. Ireland has an excellent marine current energy resource as it is an island nation and experiences excellent marine current flows. This paper reviews marine current energy devices, including a detailed up-to-date description of the current status of development. Issues such as network integration, economics, and environmental implications are addressed as well as the application and costs of MCEDs in Ireland. (author)

    Full Text Available The European Union considers creating specific economic areas due to the inheritance of each country. For the south-east European area, the characteristic is the low industrial development, as a consequence of the financial crises. Nowadays, the south-east European area becomes attractive mainly because of the tourism industry, due to the industrial downturn of the last decades. EU policies regarding the tourism industry face the actual financial crisis, which is reflected in the postponing of investments in tourism. In this article, the author intends to analyze the current stage of investments made in the Romanian tourism industry with the help of the European Union. The study also aims at finding favourable solutions for continuing investments, although the crisis persists.

Other topics of discussion include FERC's standard market design, an update of RTO West and implications for Canada. Powerex was incorporated in 1988 as a wholly-owned subsidiary of BC Hydro. British Columbia-based Powerex's heaviest trading is along the western-most states and Alberta, but it is slowly expanding into central and eastern markets. It evolved by selling and buying power at the United States Border. It received US FERC power marketing authorization in 1997 and has since seen sales jump from C$165 million to C$5.4 billion. Currently, the majority of power supply is from utilities other than BC Hydro. The presentation addresses issues such as the Federal Power Act, PUHCA and PURPA, and the 1992 Energy Policy Act which deals with expanded access to the power grid. Power Pool restructuring and FERC orders 888/889 are also discussed. 2 figs.

    Recent advances in assisted reproductive technology (ART) have made it possible to circumvent many causes of male and female infertility. The right to have a child by ART has been respected for infertile couples. However, there are currently no legal regulations concerning ART in Japan, and this has resulted in social and ethical problems. Surrogacy involves particularly complex medical, ethical, social, and legal issues, and is frequently focused on as a major social concern. Uterine transplantation (UTx) is a potential alternative for young women with uterine factor infertility due to hysterectomy for treatment of a malignant uterine tumor or massive blood loss after delivery, or because of a congenital disease such as Mayer-Rokitansky-Küster syndrome. UTx has been examined in experimental animals as a basis for establishment of fecundity for young women with uterine factor infertility. In this review, we focus on surrogacy in Japan and UTx research, and discuss the current status and concerns in this field. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The Rocky Flats Plutonium (Pu) Metal Sample Exchange program was conducted to insure the quality and intercomparability of measurements such as Pu assay, Pu isotopics, and impurity analyses. The Rocky Flats program was discontinued in 1989 after more than 30 years. In 2001, Los Alamos National Laboratory (LANL) reestablished the Pu Metal Exchange program. In addition to the Atomic Weapons Establishment (AWE) at Aldermaston, six Department of Energy (DOE) facilities Argonne East, Argonne West, Livermore, Los Alamos, New Brunswick Laboratory, and Savannah River are currently participating in the program. Plutonium metal samples are prepared and distributed to the sites for destructive measurements to determine elemental concentration, isotopic abundance, and both metallic and nonmetallic impurity levels. The program provides independent verification of analytical measurement capabilies for each participating facility and allows problems in analytical methods to be identified. The current status of the program will be discussed with emphasis on the unique statistical analysis and modeling of the data developed for the program. The discussion includes the definition of the consensus values for each analyte (in the presence and absence of anomalous values and/or censored values), and interesting features of the data and the results.

    Full Text Available Endoscopic investigation has a critical role in the diagnosis and treatment of gastrointestinal (GI diseases. Since 2001, capsule endoscopy (CE has been available for small-bowel exploration and is under continuous development. During the past decade, CE has achieved impressive improvements in areas such as miniaturization, resolution, and battery life. As a result, CE is currently a first-line tool for the investigation of the small bowel in obscure gastrointestinal bleeding and is a useful alternative to wired enteroscopy. Nevertheless, CE still has several limitations, such as incomplete examination and limited diagnostic and therapeutic capabilities. To resolve these problems, many groups have suggested several models (e.g., controlled CO2 insufflation system, magnetic navigation system, mobile robotic platform, tagging and biopsy equipment, and targeted drug-delivery system, which are in development. In the near future, new technological advances will improve the capabilities of CE and broaden its spectrum of applications not only for the small bowel but also for the colon, stomach, and esophagus. The purpose of this review is to introduce the current status of CE and to review the ongoing development of solutions to address its limitations.

    Advanced dental education has evolved in the context of societal needs and economic trends to its current status. Graduate programs have positioned their role in the context of health systems and health science education trends in hospitals, interprofessional clinical care teams, and dental schools and oral health care systems. Graduate dental education has been a critical factor in developing teams in trauma care, craniofacial disorders, pediatric and adult medicine, and oncology. The misalignment of the mission of graduate dental programs and the demands of private practice has posed a challenge in the evolution of programs as educational programs have been directed towards tertiary and indigent care while the practice community focuses on largely healthy affluent patients for complex clinical interventions. Those seeking graduate dental education today are smaller in number and include more international dental graduates than in the past. Graduate dental education in general dentistry and in the nine recognized dental specialties now includes Commission on Dental Accreditation (CODA) recognition of training standards as part of its accreditation process and a CODA accreditation process for areas of clinical education not recognized as specialties by the American Dental Association. Current types of programs include fellowship training for students in recognized specialties. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

  19. Drugs in development for toxoplasmosis: advances, challenges, and current status.

    2017-01-01

    Toxoplasma gondii causes fatal and debilitating brain and eye diseases. Medicines that are currently used to treat toxoplasmosis commonly have toxic side effects and require prolonged courses that range from weeks to more than a year. The need for long treatment durations and the risk of relapsing disease are in part due to the lack of efficacy against T. gondii tissue cysts. The challenges for developing a more effective treatment for toxoplasmosis include decreasing toxicity, achieving therapeutic concentrations in the brain and eye, shortening duration, eliminating tissue cysts from the host, safety in pregnancy, and creating a formulation that is inexpensive and practical for use in resource-poor areas of the world. Over the last decade, significant progress has been made in identifying and developing new compounds for the treatment of toxoplasmosis. Unlike clinically used medicines that were repurposed for toxoplasmosis, these compounds have been optimized for efficacy against toxoplasmosis during preclinical development. Medicines with enhanced efficacy as well as features that address the unique aspects of toxoplasmosis have the potential to greatly improve toxoplasmosis therapy. This review discusses the facets of toxoplasmosis that are pertinent to drug design and the advances, challenges, and current status of preclinical drug research for toxoplasmosis.

    In this paper, we will present the current status of radio astronomical research and outreach in Malaysia. We will also present a short history of our research group, which is currently the only radio astronomical facility in Malaysia. Our group is called the Radio Cosmology Research Lab and was established in 2005 by Dr Zamri Zainal Abidin and Prof Dr Zainol Abidin Ibrahim. We will discuss the future plans for this group including our keen interest in being part of a more global network of radio astronomers. We are already an active member of the South-East Asia Astronomy Network (SEAAN) and aims to have a radio astronomical facility in order to join the Global Very Long Baseline Interferometer (VLBI) as well becoming a research hub for the future Square Kilometer Array (SKA) project. We will also present some of the scientific goals of our group including providing a platform for radio astronomers to be able to do observations of weak and high red-shifted radio objects such as galaxy clusters and supernovae.

    Child neurology training in Canada has changed considerably over time, with increasing requirements for standardized teaching of the fundamentals of child neurology and the CanMEDS competencies. We sought to determine the current status of child neurology training in Canada as well future directions for training. A web-based survey was sent to program directors (PD's) of active pediatric neurology training programs. General questions about the programs were asked, as well as about success at the Royal College of Physicians and Surgeons of Canada (RCPSC) exam, breakdown of rotations, views on CanMEDS roles and questions on the future of pediatric neurology. 9/9 PD's completed the survey. 96.5% of all trainees successfully passed their RCPSC exam from 2001-2006. Breakdowns of the number and type of rotations for each year of training were provided. All CanMEDS roles were deemed to be important by PD's and programs have developed unique strategies to teach and assess these roles.92.6% of trainees chose to go into academic practice, with the most popular subspecialty being epilepsy. All PD's favour joint training sessions particularly for neurogenetics and neuromuscular disease. Overall, PD's suggest recruitment for future child neurologists at the medical student level but are divided as to whether we are currently training too few or too many child neurologists. This survey provides a view of the current state of pediatric neurology training in Canada and suggestions for further development of post-graduate training. In particular, attention should be given to joint educational programs as well as urgently assessing the manpower needs of child neurologists.

    Cerebral stroke is one of the most frequent causes of permanent disability or death in the western world and a major burden in healthcare system. The major portion is caused by acute ischemia due to cerebral artery occlusion by a clot. The minority of strokes is related to intracerebral hemorrhage or other sources. To limit the permanent disability in ischemic stroke patients resulting from irreversible infarction of ischemic brain tissue, major efforts were made in the last decade. To extend the time window for thrombolysis, which is the only approved therapy, several imaging parameters in computed tomography and magnetic resonance imaging (MRI) have been investigated. However, the current guidelines neglect the fact that the portion of potentially salvageable ischemic tissue (penumbra) is not dependent on the time window but the individual collateral blood flow. Within the last years, the differentiation of infarct core and penumbra with MRI using diffusion-weighted images (DWI) and perfusion imaging (PI) with parameter maps was established. Current trials transform these technical advances to a redefined patient selection based on physiological parameters determined by MRI. This review article presents the current status of MRI for acute stroke imaging. A special focus is the ischemic stroke. In dependence on the pathophysiology of cerebral ischemia, the basic principle and diagnostic value of different MRI sequences are illustrated. MRI techniques for imaging of the main differential diagnoses of ischemic stroke are mentioned. Moreover, perspectives of MRI for imaging-based acute stroke treatment as well as monitoring of restorative stroke therapy from recent trials are discussed. (orig.)

    Presently Ukraine has mixed system for dosimetric monitoring. Nuclear power plants and some major nuclear facilities have their own dosimetry services, which are responsible for regular dosimetric monitoring of workers. Rest of occupationally exposed persons is monitored by dosimetry laboratories affiliated to the territorial authorities for sanitary and epidemiology supervision. In 2002-2003 Ukrainian Ministry of Health performed survey of the status of dosimetric monitoring and inventory of critical groups requiring such monitoring. Dosimetry services in Ukraine cover about 38,000 occupationally exposed workers, including 9,100 medical professionals, 16,400 employees of 5 nuclear power plants and ca.12,400 workers dealing with other sources of occupational exposure (industry, research). Territorial dosimetry services operate in 13 of 24 regions of Ukraine, using DTU-01 manual TLD readers produced with one exception in 1988-1990. The coverage of critical groups by dosimetric monitoring is variable and ranges from 38% to 100% depending on the region. Personnel of nuclear power plants (about 16,400 workers) is monitored by their own dosimetry services achieving absolute coverage of the main staff and temporary workers. Current inadequate status of dosimetric monitoring infrastructure in Ukraine demands an urgent elaboration of the united state system for monitoring and recording of individual doses. The proposed plan would allows to bring dosimetry infrastructure in Ukraine to the modern state which would be compatible with existing and future European and international radiation protection networks. Unitary structure of Ukraine, strong administrative command and good communications between regions of the country are positive factors in favour of efficient implementation of the proposed plan. Deficiencies are associated with limited funding of this effort. (authors)

    African American men in the USA experience poorer aging-related health outcomes compared to their White counterparts, partially due to socioeconomic disparities along racial lines. Greater exposure to socioeconomic strains among African American men may adversely impact health and aging at the cellular level, as indexed by shorter leukocyte telomere length (LTL). This study examined associations between socioeconomic factors and LTL among African American men in midlife, a life course stage when heterogeneity in both health and socioeconomic status are particularly pronounced. Using multinomial logistic regression, we examined associations between multiple measures of SES and tertiles of LTL in a sample of 92 African American men between 30 to 50 years of age. Reports of greater financial strain were associated with higher odds of short versus medium LTL (odds ratio (OR)=2.21, p = 0.03). Higher income was associated with lower odds of short versus medium telomeres (OR=0.97, p = 0.04). Exploratory analyses revealed a significant interaction between educational attainment and employment status (χ 2  = 4.07, p = 0.04), with greater education associated with lower odds of short versus long telomeres only among those not employed (OR=0.10, p = 0.040). Cellular aging associated with multiple dimensions of socioeconomic adversity may contribute to poor aging-related health outcomes among African American men. Subjective appraisal of financial difficulty may impact LTL independently of objective dimensions of SES. Self-appraised success in fulfilling traditionally masculine gender roles, including being an economic provider, may be a particularly salient aspect of identity for African American men and have implications for cellular aging in this population.

  6. Hedging Financial Risks in the Economic Practices of Small Business: Current Imperatives

    Full Text Available The article considers the need to update approaches to hedging the financial risks of small businesses. Reducing the probability of financial costs and losses is of continuing relevance. It appears to be especially critical for small businesses. Small business plays a significant role in the country’s economic system as creator of jobs and as a producer of goods and services that adapts quickly to changing consumer requirements. However, its access to credit resources has certain limitations. The instability of the economic environment by individual factors can affect small businesses not less, and sometimes even more than large and medium-sized businesses. Design of the risk-management in terms of small business needs to be updated. In the current context, there is a need in re-evaluating that the efficient financial risk management can only be carried out in a complex of all the enterprise’s risks, with an increase in the planning horizon and the identification of obstacles to achieving the objective set.

    It is ny great pleasure to have this chance of speaking at twenty-first KAIF/KNS Annual Conference, with the subject of the current status and future prospects of nuclear industry in Korea. As you all know, since the start of operation in Obninsk, the former Soviet Union, on June 26th, 1954, nuclear generation in the world has expanded continuously for the past 50 years. In 1973, when the first oil crisis hit the world, there were 147 nuclear power plants in operation, supplying only 0.8% of the world energy demand. About 30 years later, by the end of last year, 443 plants were in operation in 32 countries, supplying about 16% of the world power demand. Nuclear power generation is greatly contributing to the energy security of many countries and preservation of global environments. Recently, countries all over the world are becoming aware of the values and importance of nuclear energy which can help respond to energy crises caused by a sharp rise in oil prices and protect the earth from global warming. Due to its high energy density and ability to secure fuel supply at a lower cost, in addition to its cleanliness resulting from almost no emission of greenhouse gases, nuclear power generation is the practical alternative for energy security and the prevention of global warming. However, in the rapidly changing 21st century, the nuclear industries of the world, as well as Korea, are facing more challenges than ever before. The political and social disputes on nuclear generation are continuing while we all are facing urgent challenges, including the concerns about the safety of nuclear generation, procuring site to build nuclear power plants, and the improvement of competitiveness. Please allow me to remind you that it is very important for the world's nuclear societies to cooperate together in order to overcome diverse difficulties along our path and to contribute to the development of mankind and preservation of natural environments with nuclear power as a

    After purchase of radiotherapy equipment in 2003, classic radiation therapy in Serbia will reach the highest world level. In order to define the highest standards in radiation technology, we analyzed the current status and potential perspectives of radiation therapy. An analysis of present situation in the USA, assumed as the most developed in the world, was done. Available data, collected in the last 3 years (equipment assortment, therapy modalities, workload and manpower) for 284 radiotherapy centers, out of potential 2050, were analyzed. Results were presented as crude percentage and matched to point current status. The analysis showed that CLINAC accelerators are the most popular (82.7%), as well as, ADAC (43.7%) and Focus (CMS) (27.4%) systems for therapy planning. Movement towards virtual simulation is evident (59.3%), although classic "simulation" is not fully eliminated from the radiotherapy chain. The most popular brachytherapy afterloader is Microselectron HDR (71%). About 64.4% centers use IMPAC communication/verification/record system that seems more open than Varis. All centers practice modern radiotherapy modalities and techniques (CPRT, IMRT, SRS/SRT, TBI, IORT, IVBHRT, HDR BHRT, etc.). CT and MRI availability is out of question, but PET is available in 3% of centers, however this percentage is rapidly growing. Up to 350 new patients per year are treated by one accelerator (about 35 pts. a day). Centers are relatively small and utilize 2-3 accelerators on average. Average FTE staffing norm is 4 radiation oncologists, 2-3 medical radiotherapy physicists, about 3 certified medical dosimetrists and about 6 radiotherapy technologists. In the past 5 years relative stagnation in classic radiotherapy has been observed. In spite of substantial investments in technology and consequent improvements, as well as wide introduction of computers in radiotherapy, radiotherapy results have not changed significantly.

    Cognitive function may be influenced by education, socioeconomic status, sex, and health status. Furthermore, aging interacts with these factors to influence cognition and dementia risk in late life. Factors that may increase or decrease successful cognitive aging are of critical importance, particularly if they are modifiable. The purpose of this study was to determine if economic status in late life is associated with cognition independent of socioeconomic status in early life. Cross-sectional demographic, socioeconomic, and cognitive function data were obtained in 2592 older adults (average age 71.6 years) from the Center for Disease Control's National Health and Nutrition Examination Survey (NHANES) and analyzed with linear regression modeling. Cognitive function, as measured with a test of processing speed, was significantly associated with poverty index scores after adjusting for educational attainment as an estimate of childhood socioeconomic status, ethnic background, age, health status, and sex (P status is independently associated with cognitive function in adults over age 60 years.

    Ventilator-associated pneumonia (VAP) is a common hazardous complication in ICU patients. The aim of the current review is to give an update on the current status and future recommendations for VAP prevention. This article gives an updated review of the current literature on VAP. The first part briefly reviews pathogenesis and epidemiology while the second includes an in-depth review of evidence-based practice guidelines (EBPG) and new technologies developed for prevention of VAP. VAP remains a frequent and costly complication of critical illness with a pooled relative risk of 9-27% and mortality of 25-50%. Strikingly, VAP adds an estimated cost of more than $40,000 to a typical hospital admission. An important aetiological mechanism of VAP is gross or micro-aspiration of oropharyngeal organisms around the cuff of the endotracheal tube (ETT) into the distal bronchi. Prevention of VAP is preferable. Preventative measures can be divided into two main groups: the implemen- tation of EBPGs and use of device-based technologies. EBPGs have been authored jointly by the American Thoracic Society and the Infectious Diseases Society of America. The Canadian Critical Care Trials group also published VAP Guidelines in 2008. Their recommendations are detailed in this review. The current device-based technologies include drainage of subglottic secretions, silver coated ETTs aiming to influence the internal bio-layer of the ETT, better sealing of the lower airways with ultrathin cuffs and loops for optimal cuff pressure control. EBPG consensus includes: elevation of the head of the bed, use of daily "sedation vacations" and decontamination of the oropharynx. Technological solutions should aim to use the most comprehensive combination of subglottic suction of secretions, optimization of ETT cuff pressure and ultrathin cuffs. VAP is a type of hospital-acquired pneumonia that develops more than 48 h after endotracheal intubation. Its incidence is estimated to be 9-27%, with a

    Positron Emission Tomography (PET) is a highly sensitive and accurate nuclear medicine imaging technology but the major problem of this technique is the use of radioisotopes with short half-life, less than two hours. The production and selling of short half-life radioisotopes used to be monopoly of the Brazilian Government. In 2006, a Constitutional Amendment revoked the state monopoly due to the need for the use of short half-life radioisotopes in nuclear medicine centers very far from the government production facilities. The aim of this study is to describe the current status of short half-life radioisotopes production in Brazil and discuss some licensing process. In Brazil, as has been occurring worldwide, the number of nuclear medicine centers is increasing. Currently there are 123 services performing PET scans in Brazil. There are 14 cyclotrons operating in Brazil. The type of licensing process conducted in Brazil does not take into account the population density of each state, with a free competition model being adopted. Because of this there is a lot of equipment concentrated in the Southeast and no cyclotrons operating in the Northern part of the country. One of the biggest obstacles during the licensing process is the designation of qualified personnel as operation workers and radiation safety officers. The number of cyclotron accelerators and PET/CT equipment increased in recent years. However, a number of external factors such as the distance from the nuclear medicine centers, and qualified personnel have proved crucial for the economic viability of this type of facility.

    This paper describes the current status of the second generation PACS at UCSF commenced in October 1992. The UCSF PACS is designed in-house as a hospital-integrated PACS based on an open architecture concept using industrial standards including UNIX operating system, C programming language, X-Window user interface, TCP/IP communication protocol, DICOM 3.0 image standard and HL7 health data format. Other manufacturer's PACS components which conform with these standards can be easily integrated into the system. Relevant data from HIS and RIS is automatically incorporated into the PACS using HL7 data format and TCP/IP communication protocol. The UCSF system also takes advantage of state-of-the-art communication, storage, and software technologies in ATM, multiple storage media, automatic programming, multilevel processes for a better cost-performance system. The primary PACS network is the 155 Mbits/sec OC3 ATM with the Ethernet as the back-up. The UCSF PACS also connects Mt. Zion Hospital and San Francisco VA Medical Center in the San Francisco Bay area via an ATM wide area network with a T1 line as the back-up. Currently, five MR and five CT scanners from multiple sites, two computed radiography systems, two film digitizers, one US PACS module, the hospital HIS and the department RIS have been connected to the PACS network. The image data is managed by a mirrored database (Sybase). The PACS controller, with its 1.3 terabyte optical disk library, acquires 2.5 gigabytes digital data daily. Four 2K, five, 1,600-line multiple monitor display workstations are on line in neuroradiology, pediatric radiology and intensive care units for clinical use. In addition, the PACS supports over 100 Macintosh users in the department and selected hospital sites for both images and textual retrieval through a client/server mechanism. We are also developing a computation and visualization node in the PACS network for advancing radiology research.

    Full Text Available During the last decade many electronic databases of vegetation plots were established in many countries around the world. These databases contain valuable phytosociological information assisting both governmental and NGO (Non-governmental organizations agencies to formulate strategies and on-ground plans to manage and protect nature resources. This paper provides an account on aims, current status and perspectives of building of a vegetation database for the Central Region (Najd of Saudi Arabia – the founding element of the Saudi Vegetation Database (SVD. The data stored by the database are sample plots (vegetation relevés collected according to the field techniques of the Braun-Blanquet approach (lists of taxa accompanied by semi-quantitative cover assessment, and are accompanied by general vegetation characteristics such as vegetation layering and cover, information on life-form of the recorded species, geographical coordinates, altitude, soil typology, topography and many more. More than 2900 vegetation-plot records (relevés have so far been collected in the Najd region; of these more than 2000 have already been stored using the Turboveg database platform. These field records cover many habitats such as depressions, wadis (dry river beds, agricultural lands, sand dunes, sabkhas, and ruderal habitats. The ecological information collected in the database is currently the largest set of vegetation data collated into a database in the Middle East. These data are of great importance for biodiversity studies in Saudi Arabia, since the region is recording a loss of biodiversity at a fast rate due to environmental problems such as global warming and land-use changes. We envisage that this database would catalyze further data collection on vegetation of the entire Arabian Peninsula, and shall serve as one of the most important datasets for classification and mapping of the vegetation of the Kingdom of Saudi Arabia.

    The future of oil has become an important topic of the discussion of energy policy in China. This paper attempts to present a full picture of the current status and future trends of China’s oil development through system analysis. First, we map a Sankey diagram of China’s oil flow to reveal the physical pattern of China’s oil supply and consumption. Then, we present the historical and ongoing trends of China’s oil flow from key aspects such as oil demand, oil resource availability, technology improvement, and policy adjustment. Based on these understandings, we design three scenarios of China’s oil demand in 2030, and analyze policy implications for oil saving, automotive energy development, and energy security. From the analysis, we draw some conclusions for policy decisions, such as to control the total oil consumption to avoid energy security risks, to enhance oil saving in all sectors with road transportation as the emphasis, and to increase the investment on oil production and refining to secure oil supply and reduce emissions. - Highlights: ► A Sankey Diagram to reveal the physical pattern of China’s oil supply and consumption. ► Present the ongoing trends of China’s oil development. ► Discuss important policy issues such as oil saving, energy security, and emissions reduction.

    Without adequate and sustainable radiation protection infrastructure, the benefits associated with safe use of nuclear technology and atomic energy might be jeopardized. In the United Republic of Tanzania, the Atomic Energy Act No. 7 of 2003 established the Tanzania Atomic Energy Commission as sole regulatory body responsible for regulating and controlling the safe and peaceful utilization of nuclear technology in the country. The Atomic Energy (Protection from ionizing radiation) Regulations, 2004 further specifies practices designed to ensure that unnecessary exposure of persons to ionizing radiation is avoided, that all exposures are kept as low as reasonably achievable and that all the dose limits specified in the radiation protection standards are not exceeded. This is achieved through the systems of notification, authorizations through registration and licensing, safety and security of radiation sources as well as regulatory inspections and enforcements. These activities are performed by the Commission with operational funds allocated by the Government of Tanzania. The Commission further provides other services namely individual monitoring; calibration services; education and training to radiation workers, public as well as law enforcers; and safe management of radioactive waste. Despite such achievement, still there are a lot to be done in order to strengthen the radiation protection infrastructure in Tanzania. These include issues such as gaps in our legislations, regulations and guidance, security of sources, enforcement of laws, etc. This paper describes and discusses the current status of the regulatory control activities and radiation protection services provided by the Commission and suggestions for further improvement of radiological protection infrastructure in Tanzania.

    Full Text Available Agricultural products, especially cereal grains, serve as staple foods in sub-Saharan Africa. However, climatic conditions in this region can lead to contamination of these commodities by moulds, with subsequent production of mycotoxins posing health risks to both humans and animals. There is limited documentation on the occurrence of mycotoxins in sub-Saharan African countries, leading to the exposure of their populations to a wide variety of mycotoxins through consumption of contaminated foods. This review aims at highlighting the current status of mycotoxin contamination of food products in Zimbabwe and recommended strategies of reducing this problem. Zimbabwe is one of the African countries with very little information with regards to mycotoxin contamination of its food commodities, both on the market and at household levels. Even though evidence of multitoxin occurrence in some food commodities such as maize and other staple foods exist, available published research focuses only on Aspergillus and Fusarium mycotoxins, namely aflatoxins, deoxynivalenol (DON, trichothecenes, fumonisins, and zearalenone (ZEA. Occurrence of mycotoxins in the food chain has been mainly associated with poor agricultural practices. Analysis of mycotoxins has been done mainly using chromatographic and immunological methods. Zimbabwe has adopted European standards, but the legislation is quite flexible, with testing for mycotoxin contamination in food commodities being done voluntarily or upon request. Therefore, the country needs to tighten its legislation as well as adopt stricter standards that will improve the food safety and security of the masses.

    1988-01-01

    For the past several years, the International Atomic Energy Agency (IAEA) has been investigating the possibility of exempting certain radiation sources and practices from regulatory control. Initial efforts were conducted under the general heading of de minimis. Interest in this topic arises from international recognition that a significant fraction of the wastes from industry, research, medicine, and the nuclear fuel cycle are contaminated to such low levels that applying regulatory controls may be unwarranted. The IAEA evaluation has been conducted by Advisory Groups considering two interrelated topics: to establish principles for exemption, and to apply the principles to various areas of waste management. The IAEA Advisory Groups developed the criteria from modeled assessments of the potential radiation exposure pathways and scenarios for individuals and population groups following the unrestricted release of radioactive materials. Although the scenarios and models used by the IAEA are necessarily generic, consultants to the Advisory Groups attempted to identify the most important radiation exposure pathways based on available literature. This approach is intended to provide the basic framework for the numerical derivation of generic exempt quantities that would be conservative in most situations. This paper discusses the current status of the IAEA's efforts on the subject of exemption and presents the generic results expressed as overall exemption limits for municipal wastes and materials for recycle and reuse

    Full Text Available OBJECTIVES: Plague remains a public health concern worldwide, particularly in old foci. Multiple epidemics of this disease have been recorded throughout the history of Iran. Despite the long-standing history of human plague in Iran, it remains difficult to obtain an accurate overview of the history and current status of plague in Iran. METHODS: In this review, available data and reports on cases and outbreaks of human plague in the past and present in Iran and in neighboring countries were collected, and information was compiled regarding when, where, and how many cases occurred. RESULTS: This paper considers the history of plague in Persia (the predecessor of today’s Iran and has a brief review of plague in countries in the World Health Organization Eastern Mediterranean Region, including a range of countries in the Middle East and North Africa. CONCLUSIONS: Since Iran has experienced outbreaks of plague for several centuries, neighboring countries have reported the disease in recent years, the disease can be silent for decades, and the circulation of Yersinia pestis has been reported among rodents and dogs in western Iran, more attention should be paid to disease monitoring in areas with previously reported human cases and in high-risk regions with previous epizootic and enzootic activity.

    Cancer is currently one of the most important public health problems in the world. Pancreatic cancer is a fatal disease with poor prognosis. As in most other countries, the health burden of pancreatic cancer in China is increasing, with annual mortality rates almost equal to incidence rates. The increasing trend of pancreatic cancer incidence is more significant in the rural areas than in the urban areas. Annual diagnoses and deaths of pancreatic cancer in China are now beyond the number of cases in the United States. GLOBOCAN 2012 estimates that cases in China account for 19.45% (65727/337872) of all newly diagnosed pancreatic cancer and 19.27% (63662/330391) of all deaths from pancreatic cancer worldwide. The population's growing socioeconomic status contributes to the rapid increase of China's proportional contribution to global rates. Here, we present an overview of control programs for pancreatic cancer in China focusing on prevention, early diagnosis and treatment. In addition, we describe key epidemiological, demographic, and socioeconomic differences between China and developed countries. Facts including no nationwide screening program for pancreatic cancer, delay in early detection resulting in a late stage at presentation, lack of awareness of pancreatic cancer in the Chinese population, and low investment compared with other cancer types by government have led to backwardness in China's pancreatic cancer diagnosis and treatment. Finally, we suggest measures to improve health outcomes of pancreatic cancer patients in China.

    Medical Physics is an area that applies the principles of physics to medicine, particularly in the prevention, diagnosis and treatment of diseases using ionizing and nonionizing radiation. The main attractive of medical physics is that it has a direct impact on the quality and safety of medical care in humans; this social component with direct implications for the population is of high value for Mexico. This paper describes the concepts of medical physics, trends and the current status of this discipline as a profession, which is directly related to the efforts of clinical research. It is also described what is, in my opinion, the future of medical physics in Mexico, emphasizing the fact that this field requires a substantial boost from universities and hospitals to recruit highly qualified young medical physicists and the support from government agencies such as Secretaria de Salud, Instituto Mexicano del Seguro Social and Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado through clinical research projects that allow the necessary evolution of medical physics into the hospital setting.

    The current status of Observatory "Carl Sagan" (OCS) of University of Sonora is presented. This project was born in 1996 focused to build a small solar-stellar observatory completely operated by remote control. The observatory will be at "Cerro Azul", a 2480 m peak in one of the best regions in the world for astronomical observation, at the Sonora-Arizona desert. The OCS, with three 16 cm solar telescopes and a 55 cm stellar telescope is one of the cheapest observatories, valuated in US200,000 Added to its scientific goals to study solar coronal holes and Supernovae Type 1A, the OCS has a strong educative and cultural program in Astronomy to all levels. At the end of 2001, we started the Program "Constelacion", to build small planetariums through all the countries with a cost of only US80,000. Also, the webcast system for transmission of the solar observations from the prototype OCS at the campus, was expanded to webcast educational programs in Astronomy since July of this year, including courses and diplomats for Latin American people. All of these advances are exposed here.

    Full Text Available Preimplantation genetic diagnosis (PGD is a clinically feasible technology to prevent the transmission of monogenic inherited disorders in families afflicted the diseases to the future offsprings. The major technical hurdle is it does not have a general formula for all mutations, thus different gene locus needs individualized, customized design to make the diagnosis accurate enough to be applied on PGD, in which the quantity of DNA is scarce, whereas timely result is sometimes requested if fresh embryo transfer is desired. On the other hand, preimplantation genetic screening (PGS screens embryo with aneuploidy and was also known as PGD-A (A denotes aneuploidy in order to enhance the implantation rates as well as livebirth rates. In contrasts to PGD, PGS is still under ferocious debate, especially recent reports found that euploid babies were born after transferring the aneuploid embryos diagnosed by PGS back to the womb and only very few randomized trials of PGS are available in the literature. We have been doing PGD and/or PGS for more than 10 years as one of the core PGD/PGS laboratories in Taiwan. Here we provide a concise review of PGD/PGS regarding its current status, both domestically and globally, as well as its future challenges.

    Tests with specially instrumented NASA B-737 and FAA B-727 aircraft together with several different ground friction measuring devices have been conducted for a variety of runway surface types and wetness conditions. This effort is part of the Joint FAA/NASA Aircraft Ground Vehicle Runway Friction Program aimed at obaining a better understanding of aircraft ground handling performance under adverse weather conditions and defining relationships between aircraft and ground vehicle tire friction measurements. Aircraft braking performance on dry, wet, snow-, and ice-covered runway conditions is discussed together with ground vehicle friction data obtained under similar runway conditions. For the wet, compacted snow- and ice-covered runway conditions, the relationship between ground vehicles and aircraft friction data is identified. The influence of major test parameters on friction measurements such as speed, test tire characteristics, and surface contaminant type are discussed. The test results indicate that use of properly maintained and calibrated ground vehicles for monitoring runway friction conditions should be encouraged particularly under adverse weather conditions. The current status of the runway friction program is summarized and future test plans are identified.

    SNO+ is a large liquid scintillator based experiment that reuses the Sudbury Neutrino Observatory detector. The detector, located 2 km underground in a mine near Sudbury, Canada, consists of a 12 m diameter acrylic vessel which will be filled with 780 tonnes of liquid scintillator. The main physics goal of SNO+ is to search for the neutrinoless double-beta (0νββ) decay of {sup 130}Te. During the double-beta phase, the liquid scintillator will be initially loaded with 0.3-0.5% natural tellurium. In 5 years of data taking, SNO+ expects to reach a sensitivity on the effective Majorana neutrino mass of 55-133 meV, just above the inverted neutrino mass hierarchy region. Recently, the possibility to deploy up to 10 times more natural tellurium has been investigated, by which SNO+ could explore deep into the parameter space for the inverted hierarchy in the near future. Designed as a general purpose neutrino experiment, SNO+ can additionally measure the reactor antineutrino oscillations, geo-neutrinos in a geologically-interesting location, watch supernova neutrinos and measure low-energy solar neutrinos. A first commissioning phase with the detector filled with water will begin soon. The scintillator phase is expected to start after few months of water data taking. The 0νββ decay phase is foreseen for the 2017. In this talk the current status and the broad physics program of SNO+ will be presented.

    Gastric cancer is the second leading cause of death from malignant disease worldwide and most frequently discovered in advanced stages. Because curative surgery is regarded as the only option for cure, early detection of resectable gastric cancer is extremely important for good patient outcomes. Therefore, noninvasive diagnostic modalities such as evolutionary endoscopy and positron emission tomography are utilized as screening tools for gastric cancer. To date, early gastric cancer is being treated using minimally invasive methods such as endoscopic treatment and laparoscopic surgery, while in advanced cancer it is necessary to consider multimodality treatment including chemotherapy, radiotherapy, and surgery. Because of the results of large clinical trials, surgery with extended lymphadenectomy could not be recommended as a standard therapy for advanced gastric cancer. Recent clinical trials had shown survival benefits of adjuvant chemotherapy after curative resection compared with surgery alone. In addition, recent advances of molecular targeted agents would play an important role as one of the modalities for advanced gastric cancer. In this review, we summarize the current status of diagnostic technology and treatment for gastric cancer

    Radiation processing is an alternative to conventional methods such as thermal and chemical processing in many industrial applications. In India, this technology has found extensive applications in area of healthcare, agriculture, food preservation, industry and environment. Both gamma radiation and electron beam accelerators are being utilized for this purpose. Presently, 6 commercial gamma irradiators housing about 1.5 million curie Co-60 and an annual turnover of over US$ 2 million and 3 commercial electron beam (EB) accelerators with installed capacity of 185 kW are commercially operating in India. Five demonstration plants housing a total of 0.5 million curie Co-60 have been set up to assess the techno-commercial viability of the processes such as radiation vulcanization of natural rubber latex, decontamination of spices, hygienization of sewage sludge, shelf-life extension of onions. The new areas being explored include use of electron beam treated pulp for viscose-rayon process, radiation processed 'hydrogel' burn/wound dressings and radiation processing of natural polymers. In the present paper, the current status of this program, especially the recent developments and future direction of radiation processing technology in India is reviewed. (author)

    2009-07-01

    Full Text Available Following the discovery of context-dependent synchronization of oscillatory neuronal responses in the visual system, the role of neural synchrony in cortical networks has been expanded to provide a general mechanism for the coordination of distributed neural activity patterns. In the current paper, we present an update of the status of this hypothesis through summarizing recent results from our laboratory that suggest important new insights regarding the mechanisms, function and relevance of this phenomenon. In the first part, we present recent results derived from animal experiments and mathematical simulations that provide novel explanations and mechanisms for zero and nero-zero phase lag synchronization. In the second part, we shall discuss the role of neural synchrony for expectancy during perceptual organization and its role in conscious experience. This will be followed by evidence that indicates that in addition to supporting conscious cognition, neural synchrony is abnormal in major brain disorders, such as schizophrenia and autism spectrum disorders. We conclude this paper with suggestions for further research as well as with critical issues that need to be addressed in future studies.

    Our purpose was to review the current status of carotid artery stent placement throughout the world. Surveys were sent to major interventional centers in Europe, North and South America, and Asia. Information from peer-reviewed journals was also included and supplemented the survey. The survey asked various questions regarding the patients enrolled, procedure techniques, and results of carotid stenting, including complications and restenosis. Of the centers which were sent surveys, 24 responded. The total number of endovascular carotid stent procedures that have been performed worldwide to date included 2,048 cases, with a technical success of 98.6%. Complications that occurred during carotid stent placement or within a 30-day period following placement were recorded. Overall, there were 63 minor strokes, with a rate of occurrence of 3.08%. The total number of major strokes was 27, for a rate of 1.32%. There were 28 deaths within a 30-day postprocedure period, resulting in a mortality rate of 1.37%. Restenosis rates of carotid stenting have been 4.80% at 6 mo. Endovascular stent treatment of carotid artery atherosclerotic disease is growing as an alternative to vascular surgery, especially for patients that are at high risk for standard carotid endarterectomy. The periprocedural risks for major and minor strokes and death are generally acceptable at this early stage of development.

    Full Text Available Collagen cross-linking (CXL using UVA light and riboflavin (vitamin B2 was introduced as a clinical application to stabilize the cornea by inducing cross-links within and between collagen fibers. CXL has been investigated extensively and has been shown clinically to arrest the progression of keratoconic or post-LASIK ectasia. With its minimal cost, simplicity, and proven positive clinical outcome, CXL can be regarded as a useful approach to reduce the number of penetrating keratoplasties performed. Small case series have also indicated that CXL is beneficial in corneal edema by reducing stromal swelling behavior and in keratitis by inhibiting pathogen growth. Despite these encouraging results, CXL remains a relatively new method that is potentially associated with complications. Aspects such as side effects and recurrence rates have still to be elucidated. In light of the growing interest in CXL, our paper summarizes present knowledge about this promising approach. We have intentionally endeavored to include the more relevant studies from the recent literature to provide an overview of the current status of CXL.

    2015-01-01

    Full Text Available There are many fascinating processes in the Universe which we observe in more and more in detail thanks to increasingly sophisticated technology. One of the most interesting phenomena is the life cycle of stars, their birth, evolution and death. If the stars are massive enough, they end their lives in the core-collapse supernova explosion, the one of the most violent events in the Universe. As the result, the densest objects in the Universe, neutron stars and/or black holes are created. Naturally, the physical basis of these events should be understood in line with observation. The current status of our knowledge of processes in the life of stars is far from adequate for their true understanding. We show that although many models have been constructed their detailed ability to describe observations is limited or non-existent. Furthermore the general failure of all models means that we cannot tell which are heading in the right direction. A possible way forward in modeling of high-density matter is outlined, exemplified by the quark-meson-coupling model (QMC. This model has a natural explanation for the saturation of nuclear forces and depends on very few adjustable parameters, strongly constrained by the underlying physics. Latest QMC results for compact objects and finite nuclei are presented.

  18. Current status and directions for fast reactor reprocessing

    Burch, W.D.

    1983-01-01

    The development of fast breeder reactors (FBRs) for commercial electric power production has been under way in several countries for more than 20 years. In the United States (US), as elsewhere, early work was focused on small reactors to prove the feasibility of concepts and later was followed by larger reactors to test engineering features and to develop fuel technology. Because of the perceived crisis in electrical generation expected late in this century, major efforts (including fuel cycle activities) were developed in the early 1970s to ensure the capability of developing and using this new form of nuclear power. However, because of the effects of the oil price rise and subsequent emphasis on conservation, and a slowdown of industrial growth, there has been a decline in such activities, particularly in the US, which was at one time (1970s) the world leader in reactor development. This paper provides a brief history of breeder reprocessing and describes the current status, with emphasis on US programs and glimpses into the future

    The direct use of proton and heavy ion beams for radiotherapy is a well established cancer treatment modality, which is becoming increasingly widespread due to its clear advantages over conventional photon-based treatments. This strategy is suitable when the tumor is spatially well localized. Also the use of neutrons has a long tradition. Here Boron Neutron Capture Therapy (BNCT) stands out, though on a much smaller scale, being a second-generation promising alternative for tumors which are diffuse and infiltrating. On this sector, so far only nuclear reactors have been used as neutron sources. In this paper we describe the current situation worldwide as far as the use of accelerator-based neutron sources for BNCT is concerned (so-called Accelerator-Based (AB)-BNCT). In particular we discuss the present status of an ongoing project to develop a folded Tandem-ElectroStatic-Quadrupole (TESQ) accelerator at the Atomic Energy Commission of Argentina. The project goal is a machine capable of delivering 30 mA of 2.4 MeV protons to be used in conjunction with a neutron production target based on the 7 Li(p,n) 7 Be reaction. These are the specifications needed to produce sufficiently intense and clean epithermal neutron beams to perform BNCT for deep-seated tumors in less than an hour. (author)

    Classical swine fever (CSF) is a globally significant disease of swine caused by classical swine fever virus. The virus affects the wild boars and pigs of all age groups, leading to acute, chronic, late-onset or in-apparent course of the disease. The disease causes great economic loss to the piggery industry due to mortality, stunted growth, poor reproductive performance, and by impeding the international trade of pig and pig products. In India, CSF outbreaks are reported from most of the states wherever pig rearing is practiced and more frequently from northeast states. In spite of the highly devastating nature and frequent outbreaks, CSF remained underestimated and neglected for decades in India. The country requires rapid and sensitive diagnostic tests for an early detection of infection to limit the spread of the disease. Also, effective prophylactics are required to help in control and eradication of the disease for the development of the piggery industry. This review looks into the economic impact; epidemiology of CSF highlighting the temporal and spatial occurrence of outbreaks in the last two decades, circulation, and emergence of the virus genotypes in and around the country; and the constraints in the disease control, with the aim to update the knowledge of current status of the disease in India. The article also emphasizes the importance of the disease and the need to develop rapid specific diagnostics and effective measures to eradicate the disease.

    In the past few years, new social passions have sparked on the Chinese mainland. At the centre of these burgeoning passions is a focus on animal welfare, animal treatment, and even animal rights, by the public and academic sectors. With China's rapid economic changes and greater access to information from around the world, societal awareness of animal issues is rising very fast. Hastening this paradigm shift were several highly public incidents involving animal cruelty, including exposés on bear bile harvesting for traditional Chinese medicine, the thousands of dogs rescued from China's meat trade, and the call to boycott shark fin soup and bird nest soup. This article outlines the current status of campaigning by animal advocates in China (specifically the animal rights movement) from three interlinked perspectives: wildlife conservation, companion animal protection, and laboratory animal protection. By reviewing this campaigning, we attempt to present not only the political and social impact of the concept of animal rights, but also the perceptions of, and challenges to, animal rights activities in China. 2013 FRAME.

    Veterinary therapeutics, based on the art of Materia Medica, has been practised for countless centuries, but the science of veterinary pharmacology is of very recent origin. This review traces the contribution of Materia Medica to veterinary therapeutics from the Egyptian period through to the Age of Enlightenment. The first tentative steps in the development of the science of veterinary pharmacology were taken in the 18th century, but it was not until the mid 20th century that the science replaced the art of Materia Medica. This review traces the 20th century developments in veterinary pharmacology, with emphasis on the explosion of knowledge in the 35 year period to 2010. The range of factors which have influenced the current status of the discipline are reviewed. Future developments are considered from the perspectives of what might be regarded as desirable and those innovations that might be anticipated. We end with words of encouragement for young colleagues intent upon pursuing a career in veterinary pharmacology. © 2013 Blackwell Publishing Ltd.

  4. Thorium-based nuclear fuel: current status and perspectives

    International Nuclear Information System (INIS)

    1987-03-01

    Until the present time considerable efforts have already been made in the area of fabrication, utilization and reprocessing of Th-based fuels for different types of reactors, namely: by FRG and USA - for HTRs; FRG and Brazil, Italy - for LWRs; India - for HWRs and FBRs. Basic research of thorium fuels and thorium fuel cycles are also being undertaken by Australia, Canada, China, France, FRG, Romania, USSR and other countries. Main emphasis has been given to the utilization of thorium fuels in once-through nuclear fuel cycles, but in some projects closed thorium-uranium or thorium-plutonium fuel cycles are also considered. The purpose of the Technical Committee on the Utilization of Thorium-Based Nuclear Fuel: Current Status and Perspective was to review the world thorium resources, incentives for further exploration, obtained experience in the utilization of Th-based fuels in different types of reactors, basic research, fabrication and reprocessing of Th-based fuels. As a result of the panel discussion the recommendations on future Agency activities and list of major worldwide activities in the area of Th-based fuel were developed. A separate abstract was prepared for each of the 9 papers in this proceedings series

  5. Management of reprocessed uranium. Current status and future prospects

    International Nuclear Information System (INIS)

    2007-02-01

    There is worldwide interest in developing advanced and innovative technologies for nuclear fuel cycles, minimizing waste and environmental impacts. As of the beginning of 2003, about 171000 tonnes heavy metal spent nuclear fuel is in storage, while smaller amounts have been reprocessed. In several countries, including France, India, Japan and the Russian Federation, spent fuel has been viewed as a national energy resource. Some countries hold reprocessed uranium as the result of their commercial reprocessing service contracts for reprocessing the spent fuel of others. Reprocessed uranium has a potential value for recycling either directly or after appropriate treatment. This report analyses the existing options, approaches and developments in the management of reprocessed uranium. It includes the technical issues involved in managing reprocessed uranium which are RepU arisings, storage, chemical conversion, re-enrichment, fuel fabrication, transport, reactor irradiation, subsequent reprocessing and disposal options, as well as assessment of holistic environmental impacts. The objective of this document is to overview the information on the current status and future trends in the management of RepU and to identify major issues to be considered for future projects

    A PSR for a research reactor became a legal requirement as the Nuclear Safety Act was amended and came into effect in 2014. This paper describes the current status and methodology of the first Periodic Safety Review (PSR) of HANARO that is being performed. The legal requirements, work plan, and process of implementing a PSR are described. Because this is the first PSR for a research reactor, it is our understating that the operating organization and regulatory body should communicate well with each other to complete the PSR in a timely manner. The first PSR of HANARO is under way. In order to achieve a successful result, activities of the operation organization such as scheduling, maintaining consistency in input data for review, and reviewing the PSR reports that will require intensive resources should be well planned. This means the operating organization needs to incorporate appropriate measures to ensure the transfer of knowledge and expertise arising from the PSR via a contractor to the operation organization. It is desirable for the Regulatory Body to be involved in all stage of the PSR to prevent any waste of resources and minimize the potential for a reworking of the PSR and the need for an additional assessment and review as recommended by foreign experts.

    Veterinary public health (VPH) assumes huge significance in developing countries such as India. However, the implementation of VPH services throughout the country is still in its infancy. From 1970 onwards, many institutes, national and international organisations, professional societies, policies and personalities have contributed towards the development of VPH in India. Nevertheless, there is an urgent need to develop VPH still further as there are many issues, such as high population density, the re-emergence of zoonotic pathogens, environmental pollution and antimicrobial resistance, that require attention. The time has surely come to involve all stakeholders, ranging from primary producers (e.g., farmers) to policy-makers, so as to garner support for the holistic implementation of VPH services in India. To improve VPH activities and services, science-based policies enforced through stringent regulation are required to improve human, animal and environmental health. The emergence of the 'One Health' concept has ushered in new hopes for the resurrection of VPH in India. Applying tools such as the World Organisation for Animal Health (OlE) Day One Competencies and the OlE Tool for the Evaluation of Performance of Veterinary Services (PVS Tool) is essential to improve the quality of national Veterinary Services and to identify gaps and weaknesses in service provision, which can be remedied to comply with the OlE international standards. VPH initiatives started modestly but they continue to grow. The present review is focused on the current status and future needs of VPH in India.

    The development and integration of new detector payloads has been an important part of the Advanced Virgo (AdV) project, the major upgrade of the Virgo interferometric detector of Gravitational Waves, aiming to increase the detector sensitivity by one order of magnitude. During the integration phase of the new AdV payloads with monolithic suspension of mirrors we experienced systematic suspension failures later identified as caused by dust contamination of the vacuum system. In order to not postpone the detector commissioning, making possible to join the LIGO O2 observation run, the Collaboration decided to proceed with the integration of the payloads relying on steel wire suspensions for all the mirrors. In this proceeding the status of the currently integrated payloads is reported, including their angular control characterization and the Q-factor measurements for test mass steel wire suspensions. The payload upgrade for the re-integration of monolithic suspensions after the O2 run is reported in the last section.

    To identify the current status of theory evaluation in nursing and provide directions for theory evaluation for future development of theoretical bases of nursing discipline. Theory evaluation is an essential component in development of nursing knowledge, which is a critical element in development of nursing discipline. Despite earlier significant efforts for theory evaluation in nursing, a recent decline in the number of theory evaluation articles was noted and there have been few updates on theory evaluation in nursing. Discussion paper. A total of 58 articles published from 2003-2014 were retrieved through searches using the PUBMED, PsyInfo and CINAHL. The articles were sorted by the area of evaluation and analysed to identify themes reflecting the theory evaluation process. Diverse ways of theory evaluation need to be continuously used in future theory evaluation efforts. Six themes reflecting the theory evaluation process were identified: (a) rarely using existing theory evaluation criteria; (b) evaluating specifics; (c) using various statistical analysis methods; (d) developing instruments; (e) adopting in practice and education; and (f) evaluating mainly middle-range theories and situation-specific theories. © 2015 John Wiley & Sons Ltd.

    Teleoperated medical robotic systems allow procedures such as surgeries, treatments, and diagnoses to be conducted across short or long distances while utilizing wired and/or wireless communication networks. This study presents a systematic review of the relevant literature between the years 2004 and 2015, focusing on medical teleoperated robotic systems which have witnessed tremendous growth over the examined period. A thorough insight of telerobotics systems discussing design concepts, enabling technologies (namely robotic manipulation, telecommunications, and vision systems), and potential applications in clinical practice is provided, while existing limitations and future trends are also highlighted. A representative paradigm of the short-distance case is the da Vinci Surgical System which is described in order to highlight relevant issues. The long-distance telerobotics concept is exemplified through a case study on diagnostic ultrasound scanning. Moreover, the present review provides a classification into short- and long-distance telerobotic systems, depending on the distance from which they are operated. Telerobotic systems are further categorized with respect to their application field. For the reviewed systems are also examined their engineering characteristics and the employed robotics technology. The current status of the field, its significance, the potential, as well as the challenges that lie ahead are thoroughly discussed.

    The resistance switching behaviour of several materials has recently attracted considerable attention for its application in non-volatile memory (NVM) devices, popularly described as resistive random access memories (RRAMs). RRAM is a type of NVM that uses a material(s) that changes the resistance when a voltage is applied. Resistive switching phenomena have been observed in many oxides: (i) binary transition metal oxides (TMOs), e.g. TiO 2 , Cr 2 O 3 , FeO x and NiO; (ii) perovskite-type complex TMOs that are variously functional, paraelectric, ferroelectric, multiferroic and magnetic, e.g. (Ba,Sr)TiO 3 , Pb(Zr x Ti 1−x )O 3 , BiFeO 3 and Pr x Ca 1−x MnO 3 ; (iii) large band gap high-k dielectrics, e.g. Al 2 O 3 and Gd 2 O 3 ; (iv) graphene oxides. In the non-oxide category, higher chalcogenides are front runners, e.g. In 2 Se 3 and In 2 Te 3 . Hence, the number of materials showing this technologically interesting behaviour for information storage is enormous. Resistive switching in these materials can form the basis for the next generation of NVM, i.e. RRAM, when current semiconductor memory technology reaches its limit in terms of density. RRAMs may be the high-density and low-cost NVMs of the future. A review on this topic is of importance to focus concentration on the most promising materials to accelerate application into the semiconductor industry. This review is a small effort to realize the ambitious goal of RRAMs. Its basic focus is on resistive switching in various materials with particular emphasis on binary TMOs. It also addresses the current understanding of resistive switching behaviour. Moreover, a brief comparison between RRAMs and memristors is included. The review ends with the current status of RRAMs in terms of stability, scalability and switching speed, which are three important aspects of integration onto semiconductors. (review article)

    Increasing the level of diversity among ophthalmologists may help reduce disparities in eye care. To assess the current and future status of diversity among ophthalmologists in the workforce by sex, race, and ethnicity in the context of the available number of medical students in the United States. Data from the Association of American Medical Colleges, the American Medical Association, and US Census were used to evaluate the differences and trends in diversity among ophthalmologists, all full-time faculty except ophthalmology, ophthalmology faculty, ophthalmology residents, medical school students, and the US population between 2005 and 2015. For 2014, associations of sex, race, and ethnicity with physician practice locations were assessed. Proportions of ophthalmologists stratified by sex, race, and ethnicity between 2005 and 2015. Women and minority groups traditionally underrepresented in medicine (URM)-black, Hispanic, American Indian, Alaskan Native, Native Hawaiian, and Pacific Islander-were underrepresented as practicing ophthalmologists (22.7% and 6%, respectively), ophthalmology faculty (35.1% and 5.7%, respectively), and ophthalmology residents (44.3% and 7.7%, respectively), compared with the US population (50.8% and 30.7%, respectively). During the past decade, there had been a modest increase in the proportion of female practicing ophthalmologists who graduated from US medical schools in 1980 or later (from 23.8% to 27.1%; P workforce despite an available pool of medical students. Given the prevalent racial and ethnic disparities in eye care and an increasingly diverse society, future research and training efforts that increase the level of diversity among medical students and residents seems warranted.

  14. Neutron star matter equation of state: current status and challenges

    2014-09-01

    Neutron star matter has a variety of constituents and structures depending on the density; neutron-rich nuclei surounded by electrons and drip neutrons in the crust, pasta nuclei at the bottom of inner crust, and uniform isospin-asymmetric nuclear matter in a superfluid state in the outer core. In the inner core, the neutron Fermi energy becomes so large that exotic constituents such as hyperons, mesons and quarks may emerge. Radioactive beam and hypernuclear experiments provide information on the symmetry energy and superfluidity in the crust and outer core and on the hyperon potentials in the inner core, respectively. Cold atom experiments are also helpful to understand pure neutron matter, which may be simulated by the unitary gas. An equation of state (EOS) constructed based on these laboratory experiments has to be verified by the astronomical observations such as the mass, radius, and oscillations of neutron stars. One of the key but missing ingredients is the three-baryon interactions such as the hyperon-hyperon-nucleon (YYN) interaction. YYN interaction is important in order to explain the recently discovered massive neutron stars consistently with laboratory experiments. We have recently found that the ΛΛ interaction extracted from the ΛΛ correlation at RHIC is somewhat stronger than that from double Λ hypernuclei. Since these two interactions corresponds to the vacuum and in-medium ΛΛ interactions, respectively, the difference may tell us a possible way to access the YYN interaction based on experimental data. In the presentation, after a review on the current status of neutron star matter EOS studies, we discuss the necessary tasks to pin down the EOS. We also present our recent study of ΛΛ interaction from correlation data at RHIC.

    Livestock models have contributed significantly to biomedical and surgical advances. Their contribution is particularly prominent in the areas of physiology and assisted reproductive technologies, including understanding developmental processes and disorders, from ancient to modern times. Over the past 25 years, biomedical research that traditionally embraced a diverse species approach shifted to a small number of model species (e.g. mice and rats). The initial reasons for focusing the main efforts on the mouse were the availability of murine embryonic stem cells (ESCs) and genome sequence data. This powerful combination allowed for precise manipulation of the mouse genome (knockouts, knockins, transcriptional switches etc.) leading to ground-breaking discoveries on gene functions and regulation, and their role in health and disease. Despite the enormous contribution to biomedical research, mouse models have some major limitations. Their substantial differences compared with humans in body and organ size, lifespan and inbreeding result in pronounced metabolic, physiological and behavioural differences. Comparative studies of strategically chosen domestic species can complement mouse research and yield more rigorous findings. Because genome sequence and gene manipulation tools are now available for farm animals (cattle, pigs, sheep and goats), a larger number of livestock genetically engineered (GE) models will be accessible for biomedical research. This paper discusses the use of cattle, goats, sheep and pigs in biomedical research, provides an overview of transgenic technology in farm animals and highlights some of the beneficial characteristics of large animal models of human disease compared with the mouse. In addition, status and origin of current regulation of GE biomedical models is also reviewed.

    Objectives This study presents the current status of nursing informatics education, the content covered in nursing informatics courses, the faculty efficacy, and the barriers to and additional supports for teaching nursing informatics in Korea. Methods A set of questionnaires consisting of an 18-item questionnaire for nursing informatics education, a 6-item questionnaire for faculty efficacy, and 2 open-ended questions for barriers and additional supports were sent to 204 nursing schools via email and the postal service. Nursing schools offering nursing informatics were further asked to send their syllabuses. The subjects taught were analyzed using nursing informatics competency categories and other responses were tailed using descriptive statistics. Results A total of 72 schools (35.3%) responded to the survey, of which 38 reported that they offered nursing informatics courses in their undergraduate nursing programs. Nursing informatics courses at 11 schools were taught by a professor with a degree majoring in nursing informatics. Computer technology was the most frequently taught subject (27 schools), followed by information systems used for practice (25 schools). The faculty efficacy was 3.76 ± 0.86 (out of 5). The most frequently reported barrier to teaching nursing informatics (n = 9) was lack of awareness of the importance of nursing informatics. Training and educational opportunities was the most requested additional support. Conclusions Nursing informatics education has increased during the last decade in Korea. However, the proportions of faculty with degrees in nursing informatics and number of schools offering nursing informatics courses have not increased much. Thus, a greater focus is needed on training faculty and developing the courses. PMID:27200224

  17. Current status of brachytherapy in cancer treatment – short overview

    Janusz Skowronek

    2017-12-01

    Full Text Available Cancer incidence and mortality depend on a number of factors, including age, socio-economic status and geographical location, and its prevalence is growing around the world. Most of cancer treatments include external beam radiotherapy or brachytherapy. Brachytherapy, a type of radiotherapy with energy from radionuclides inserted directly into the tumor, is increasingly used in cancer treatment. For cervical and skin cancers, it has become a standard therapy for more than 100 years as well as an important part of the treatment guidelines for other malignancies, including head and neck, skin, breast, and prostate cancers. Compared to external beam radiotherapy, brachytherapy has the potential to deliver an ablative radiation dose over a short period of time directly to the altered tissue area with the advantage of a rapid fall-off in dose, and consequently, sparing of adjacent organs. As a result, the patient is able to complete the treatment earlier, and the risks of occurrence of another cancer are lower than in conventional radiotherapy treatment. Brachytherapy has increased its use as a radical or palliative treatment, and become more advanced with the spread of pulsed-dose-rate and high-dose-rate afterloading machines; the use of new 3D/4D planning systems has additionally improved the quality of the treatment. The aim of the present study was to present short summaries of current studies on brachytherapy for the most frequently diagnosed tumors. Data presented in this manuscript should help especially young physicians or physicists to explore and introduce brachytherapy in cancer treatments.

    2007-04-11

    Forensic science is gaining some solid ground in the area of effective crime prevention, especially in the areas where more sophisticated use of available technology is prevalent. All it takes is high-level cooperation among nations that can help them deal with criminality that adopts a cross-border nature more and more. It is apparent that cooperation will not be enough on its own and this development will require a network of qualified forensic laboratories spread over Europe. It is argued in this paper that forensic science laboratories play an important role in the fight against crime. Another, complimentary argument is that forensic science laboratories need to be better involved in the fight against crime. For this to be achieved, a good level of cooperation should be established and maintained. It is also noted that harmonization is required for such cooperation and seeking accreditation according to an internationally acceptable standard, such as ISO/IEC 17025, will eventually bring harmonization as an end result. Because, ISO/IEC 17025 as an international standard, has been a tool that helps forensic science laboratories in the current trend towards accreditation that can be observed not only in Europe, but also in the rest of the world of forensic science. In the introduction part, ISO/IEC 17025 states that "the acceptance of testing and calibration results between countries should be facilitated if laboratories comply with this international standard and if they obtain accreditation from bodies which have entered into mutual recognition agreements with equivalent bodies in other countries using this international standard." Furthermore, it is emphasized that the use of this international standard will assist in the harmonization of standards and procedures. The background of forensic science cooperation in Europe will be explained by using an existing European forensic science network, i.e. ENFSI, in order to understand the current status of forensic

    The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using (192)Ir (26 centers) or (60)Co (two centers). Among the 26 centers using (192)Ir sources, 11 treated fewer than 40 patients per year. In the two centers using (60)Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy.

  1. Policies for second generation biofuels: current status and future challenges

    Current state-of-the-art knowledge concludes that green house gas (GHG) emissions must be controlled and reduced within the next 30-40 years. The transport sector contributes almost a fifth of the current global emissions, and its share is likely to increase in the future. The US and a number of European countries have therefore introduced various support schemes for research and development (RandD) of low emission fuels that can potentially replace the current fossil fuels. One such alternative is biofuels. The advantage of biofuels are that it is easy to introduce into the transport sector. On the other hand, recent research papers question whether the supply of feedstock is sufficient, and to what extent biofuels lead to GHG emission reductions. This report reviews the current status of second generation biofuels. Second generation biofuels are made from cellulose, which according to our survey of the literature, is in more abundant supply than the first generation biofuels feedstocks. Furthermore, it seems to have the potential to reduce GHG emissions from the transport sector without leading to devastating land use changes, which recent critique has held against first generation biofuels. Given that governments have decided to support RandD of low emission fuels, we ask the following questions: Should second generation biofuels receive RandD support to the same extent as other low emission fuels like hydrogen? How should support schemes for second generation biofuels be designed? Second generation biofuels can be divided according to the production process into thermo-chemical and bio-chemical. With respect to the thermo-chemical process the potential for cost reductions seems to be low. On the other hand, ethanol made from cellulose using the biochemical conversion process is far from a ripe technology. Expert reports point to several potential technological breakthroughs which may reduce costs substantially. Hence, cellulosic ethanol, should receive direct

    We attempted to identify the risk factors that may affect mental health status of the international students and we conducted the survey using a self-administered questionnaire. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. The students were divided into two groups; (1) those who received scholarships and (2) those who didn't since we thought the division represented practical patterns of their financial status. The associations of socio-demographic characteristics with depressive symptoms were examined. Of the 726 students, 480 (66.1%) responded and 207 (43.1%) had depressive symptoms. The logistic regression analysis indicated that quality of sleep, amount of exercise, and housing conditions--but not financial status--were statistically associated with the risk of developing depressive symptoms. Although the inversion of the cause and effect is yet to be ascertained, the students who are unsatisfied with their housing conditions, quality of sleep and less exercise need more attention.

  8. Current Status and Future Directions of Targeted Peptide Radionuclide Therapy

    2009-01-01

    Current status: Peptide receptor radionuclide therapy (PRRT) is currently almost exclusively targeted at the somatostatin receptor (sst). Of the 5 receptor subtypes, sst2 is frequently very highly expressed at the cell surface of neuroendocrine tumors (NET). Octreotide is a small and stable derivative of native somatostatin, which can be very well labeled with therapeutic radionuclides such as the beta-emitters ''9''0Y, ''1''7''7Lu or the Auger emitter ''1''1''1In, chelated in DTPA or DOTA, linked to the peptide. All current therapeutic octreotide derivatives are agonists that are internalized in the cell. The affinity for the sst2 receptor is better for [DOTA,Tyr''3]octreotate than for [DOTA,Tyr''3]octreotide or [DTPA]octreotide. ''9''0Y is a pure beta-emitter, with a half-life of 2.7 days, a high energy of 2.270 MeV, and a maximum penetration in tissue of 12mm. ''1''7''7Lu with a half-life of 6.7 days emits a low abundance of gamma photons as well as beta particles of 497 keV, with a maximum tissue penetration of 2 mm. ''1''7''7Lu-[DOTA,Tyr''3]octreotate (Lu-DOTATE), ''9''0Y-[DOTA,Tyr''3]octreotate (Y-DOTATATE) and ''9''0Y-[DOTA,Tyr''3]octreotide (Y-DOTATOC) are today the most frequently used therapeutic radiopeptides. Main inclusion criteria: inoperable and/or metastatic NET, receptor-positivity in all known lesions demonstrated by sufficient uptake on ''1''1''1In-octreotide scintigraphy (intensity > liver parenchyma), life expectancy at least 3-6 months, sufficient bone marrow reserve (hemoglobin (HGB) ≥ 5 mmol/L, white blood cells (WBC) ≥ 2*10 9 /L, platelets (PLT) ≥ 75*10 12 /L), sufficient renal function (serum creatinine 40 mL/min), sufficient hepatic and cardiac reserve. Karnofski score ≥50. Efficacy: several groups have reported objective response rates (RECIST or WHO/SWOG; CT or MRI based). Complete remission (CR) is rarely seen, partial remission (PR; >50% shrinkage SWOG) in 7% - 37%, minor remission (MR, 25% - 50% shrinkage) in 13% - 17

    Full Text Available Antiepileptic drugs (AEDs are extensively used worldwide to treat a wide range of disorders other than epilepsy, such as neuropathic pain, migraine and bipolar disorder. Due to this situation more than 20 new third-generation AEDs have been introduced in the market recently. The future design of new AEDs must also have potential to help in the non-epileptic disorders. The wide acceptance of second generation AEDs for the management of various Non-epileptic disorders has caused the emergence of generics in the market. The wide use of approved AEDs outside epilepsy is based on both economic and scientific reasons. Bipolar disorders, migraine prophylaxis, fibromyalgia and neuropathic pain represent the most attractive indication expansion opportunities for anticonvulsant developers, providing blockbuster revenues. Strong growth in non-epilepsy conditions will see Pfizer’s Lyrica become the market leading brand by 2018. In this review we mainly focus on the current status of new AEDs in the treatment of chronic pain and migraine prophylaxis. AEDs have a strong analgesic potential and this is demonstrated by the wide use of carbamazepine in trigeminal neuralgia and sodium valproate in migraine prophylaxis. At present, data on the new AEDs for non-epileptic conditions are inconclusive. Not all AEDs are effective in the management of neuropathic pain and migraine. Only those AEDs whose mechanisms of action are match with pathophysiology of the disease, have potential to show efficacy in non-epileptic disorder. For this better understanding of the pathophysiology of the disease and mechanisms of action of new AEDs are essential requirement before initiating pre-clinical and clinical trials. Many new AEDs show good results in the animal model and open-label studies but fail to provide strong evidence at randomized, placebo-controlled trials. The final decision regarding the clinical efficacy of the particular AEDs in a specific non-epileptic disorder

    . Available MELiSSA closed environment crop growth data were used to develop a first photosynthetic model representing the basic carbon fixation mechanisms. This model will be further elaborated in the course of this study to predict yield, oxygen production and transpi-ration. As an ultimate goal the model is intended to simulate the composition of the different plant organs (root, shoot, fruit/seed or tuber) for each crop under various conditions. For the validation of this model an extensive amount of data sets are needed. Current plant growth bench test setups will provide part of the required data. To gain more precise and detailed datasets, a highly closed plant growth chamber (Plant Characterization Unit, PCU) is under development. The PCU will provide accurate mass balances for carbon, water, oxygen and other elements with statistical reliability. This reliability is achieved through a high degree of closure and environment homogeneity. The PCU will also provide data for the above described plant characterization studies. The general work approach, the current status and future steps will be illustrated.

    Namibia has one of the highest human immunodeficiency virus (HIV) prevalence rates and one of the highest rates of orphanhood in the world, and older caregivers provide much of the care to Namibians living with HIV and acquired immune deficiency syndrome (AIDS) (UNAIDS, 2014). In this study, the authors explore how financial status, social support, and health were related to the resilience of caregivers caring for people affected by HIV and AIDS in rural northern Namibia, Africa. Data were collected through a structured interview from (N = 147) caregivers from the Zambezi region. Findings from this study show that employment and physical health were significantly associated with increased resilience in older caregivers. Our findings point to the need for employment assistance and health services to improve the resilience of caregivers caring for people living with HIV and AIDS. We conclude that there is a need for more vigorous concerted efforts from public and private sector practitioners and policy makers to create more sustained formal employment opportunities and intervention programs aimed at improving the overall health of older HIV caregivers, especially those residing in rural HIV endemic communities in developing countries.

    Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

    1993-01-01

    Application of Lower Hybrid (LH) Current Drive (CD) in the DIII-D tokamak has been studied at LLNL, off and on, for several years. The latest effort began in February 1992 in response to a letter from ASDEX indicating that the 2.45 GHz, 3 MW system there was available to be used on another device. An initial assessment of the possible uses for such a system on DIII-D was made and documented in September 1992. Multiple meetings with GA personnel and members of the LH community nationwide have occurred since that time. The work continued through the submission of the 1995 Field Work Proposals in March 1993 and was then put on hold due to budget limitations. The purpose of this document is to record the status of the work in such a way that it could fairly easily be restarted at a future date. This document will take the form of a collection of Appendices giving both background and the latest results from the FY 1993 work, connected by brief descriptive text. Section 2 will describe the final workshop on LHCD in DIII-D held at GA in February 1993. This was an open meeting with attendees from GA, LLNL, MIT and PPPL. Summary documents from the meeting and subsequent papers describing the results will be included in Appendices. Section 3 will describe the status of work on the use of low frequency (2.45 GHZ) LH power and Parametric Decay Instabilities (PDI) for the special case of high dielectric in the edge regions of the DIII-D plasma. This was one of the critical issues identified at the workshop. Other potential issues for LHCD in the DIII-D scenarios are: (1) damping of the waves on fast ions from neutral beam injection, (2) runaway electrons in the low density edge plasma, (3) the validity of the WKB approximation used in the ray-tracing models in the steep edge density gradients

    and drug regimens for anti-TB chemotherapy. There are a number of difficulties in drug-design for the development of new drug formulations with increased potential for antimycobacterial effects, excellent pharmacokinetics, and tolerability. It should be emphasized that the most urgent goal of chemotherapy of TB and MAC infections, especially that associated with HIV infection, is to develop highly active, low-cost drugs which can be used not only in industrialized countries but also in developing countries, since the incidences of AIDS-associated intractable TB and MAC infections are rapidly increasing in the latter. We strongly wish a great advance of fundametal and practical studies in developing such kinds of new anti-TB drugs in the near future. 1. Prospects for non-clinical or clinical development of new antituberculous drugs in relation to corporate strategy: Kenji NAMBA (New Product Research Laboratories I, Daiichi Pharmaceutical Co., Ltd.) Tuberculosis (TB) remains one of the deadliest threats to public health. No new anti-TB drugs have been brought into the clinic in the past 40 years. Current non-clinical works with progressed technology and Global Alliance for TB Drug Development, a non-profit organization established in 2000, accelerate research and development of faster-acting anti-TB compounds. We reviewed the status of new types of compounds which are being developed as anti-TB drug, such as diarylquinoline (TMC 207), nitroimidazole (PA-824 and OPC-67683), and moxifloxacin (MFLX). We also discussed the best clinical development plans for new-TB drugs in relation to corporate strategy. 2.

    2000-01-01

    In most developed countries of the world, deregulation of electricity markets has been established: competition is fierce, and utilities have to improve the competitiveness of their plants. It is an important challenge for nuclear power plants: a smart way to deal with this problem is life extension of existing units. The financial stakes associated with maintaining or extending the lifetime of nuclear power stations are very high; thus, if their lifetime is shortened by about ten years, dismantling and renewal would be brought forward which would increase their costs by several tens of billions of French francs. Furthermore, every extra year of operation of a 900 MWe unit should save about 500 million French francs per year on financial charges that would be necessary for a new investment, provided that maintenance costs do not become excessive. In order to succeed, utilities must improve their knowledge of ageing mechanisms, demonstrate to safety authorities the feasibility of life extension (especially taking into account critical components), operate existing units in an exemplary way, manage and master the long-term evolution of the safety reference state.

    As a renewable energy technology, the ground-source heat pump (GSHP) technologies have increasingly attracted world-wide attention due to their advantages of energy efficiency and environmental friendliness. This paper presents Chinese research and application on GSHP followed by descriptions of patents. The policies related to GSHP are also introduced and analyzed. With the support of Chinese government, several new heat transfer models and two new GSHP systems (named pumping and recharging well (PRW) and integrated soil cold storage and ground-source heat pump (ISCS and GSHP) system) have been developed by Chinese researchers. The applications of GSHP systems have been growing rapidly since the beginning of the 21st century with financial incentives and supportive government policies. However, there are still several challenges for the application of GSHP systems in large scale. This paper raises relevant suggestions for overcoming the existing and potential obstacles. In addition, the developing and applying prospects of GSHP systems in China are also discussed.

    Full Text Available Loss or impairment of auditory sense is the most prevalent deficit of all the sensory organs. With virtually no mortality, hearing impairment causes huge impact on one′s social, educational and economic well-being. There are 5-6 infants who are hard of hearing out of 1000 neonates. They will not be identified till they attain 2 or more years of age, by then irreversible damage would have been done. Universal screening for hearing of new-borns is the only way to decrease the burden of deafness in our society. There are tools available which can be administered by health workers after initial training for screening the infants for hearing impairment. Under the aegis of National Programme for Prevention and Control of Deafness (NPPCD of India universal screening can and should be applied. The programme would entail additional financial burden for the initial purchase of screening machines and rehabilitating the identified children.

    Since MRI is being applied as a diagnostic imaging method, there is no other field of application of MRI that has been causing debates and emotions of such controversial nature as has MRI of the breast. Advocates of the method emphasize the fact that MR mammography is capable of detecting carcinomas not shown by all other available methods, and diagnostic findings even permit identification of malignomas with a high accuracy. As a concluding statement of the analysis of the pros and cons it can be said that establishment of a routine diagnostic method offering higher sensitivity and specificity than other available methods, free of radiological risks at that, certainly would be appropriate. Those supporting MR mammography believe that this method is up to all requirements stated. However, financial constraints in the public health sector demand that the range of indications be well defined. (orig./AJ) [de

    1996-10-01

    China has been carrying out active international cooperation aiming to be a country where is to be an economical super power and an advanced country in nuclear power technology by the year early 2000, and China also has begun to be recognized as the largest potential market for the construction of nuclear power plants(NPPs) expecting to construct more than thirty nuclear power units by the year 2020. China has advanced technology in the basic nuclear science including liquid metal breeder reactor technology, nuclear material, medium and small size power plants, and isotope production technology, and also China has complete nuclear fuel cycle technology. However, China still has low NPP technology. Therefore, it is expected that China may have complementary cooperative relationship with China, it is expected that Korea may have an access to the advanced Chinese nuclear science technology, and may have a good opportunity to explore the Chinese market actively exporting excellent Korean NPP technology, and further may have a good position to the neighboring Asian countries' NPP markets. From this perspective, general Chinese social status, major nuclear R and D activity status, and correct NPP and technology status have been analyzed in this report, and this report is expected to be a useful resource for cooperating with China in future. 10 tabs., 6 figs., 16 refs.

    2015-01-01

    The paper deals with parental employment status and its relationship to adolescents' self-reported health. It studies the role of the financial situation, parent-adolescent relationship and adolescent resilience in the relationship between parental employment status and adolescents' self-rated health, vitality and mental health. Multiple regression analyses were used to analyse questionnaire data obtained from 2799 adolescents (mean age 14.3) in 2006. The results show a negative association of the father's, but not mother's unemployment or non-employment with adolescents' health. Regression analyses showed that neither financial strain nor a poor parent-adolescent relationship or a low score in resilience accounted for the relationship between the father's unemployment or non-employment and poorer adolescent health. Furthermore, resilience did not work as a buffer against the negative impact of fathers' unemployment on adolescents' health.

    The East/Japan Sea (hereafter the East Sea) is changing quickly. Warming and structural changes in the East Sea have been reported by CREAMS, an acronym of ″Circulation Research of the East Asian Marginal Seas″, which began in 1993 as an international research program to understand the water mass structure and circulation in the East Sea (Kim and Kim, 1996; Kim, 1997; Kim et al., 2001, 2002). A subsequent research program of the EAST-I, an acronym of ″the East Asian Seas Time-series″, was launched by PICES (North Pacific Marine Science Organization) and financially supported by the Korean government, allowing us to deepen our knowledge about rapidly changing processes in the East Sea (Chang et al., 2010). Although there has been considerable progress in developing a mechanistic understanding of the East Sea ecosystem responses to disturbances, more comprehensive studies are needed to address the impacts of the frequency and intensity of disturbances on marine ecosystems. The most important question of the research has been: how do environmental changes affect structural and functional biodiversity? Recently launched research on ″Long-term change of structure and function in marine ecosystems of Korea″, which has been supported by the Korean government since 2011, has given an unprecedented insight into the ecosystem dynamics in the East Sea. It therefore seems an appropriate time to devote a special issue to the topic of ″Current status of the East Sea ecosystem in a changing world″.

    Dengue is a significant global health problem. Even though a vaccine against dengue is now available, which is a notable achievement, its long-term protective efficacy against each of the 4 dengue virus serotypes remains to be definitively determined. Consequently, drugs directed at the viral targets or critical host mechanisms that can be used safely as prophylaxis or treatment to effectively ameliorate disease or reduce disease severity and fatalities are still needed to reduce the burden of dengue. This review will provide a brief account of the status of therapeutics research and development for dengue. © The Author 2016.

    2004-01-01

    After the collapse, in 1989, of the centralized communist regimes in the Central and Eastern Europe, the Romanian economy experienced significant changes. By 2001 the industrial production decline caused a dramatic drop in the country's electricity consumption. Despite it, the power sector has to cope with many difficulties to cover the electricity demand. Under the circumstances of the economy restructuring, the problems of the Romanian power sector became acute: most of thermal power units are aged (older than 20 years), with low efficiency, low performance indicators, high costs, large staff number; the dependence on imported fossil fuel is high; the environment protection requirements - emphasized by the European institutions - not met; lack of the capital required for fixing these questions. The lack of financial sources at the thermal power plants made the purchase of fuel from import extremely complicated; also, the maintenance programs at the power plants could not be accomplished. It was very difficult to attract investment funds for rehabilitation work or for construction of new capacities in the power plants. Meanwhile, in the last three years, a gradual recovery of the Romanian industry occurred. Now, it becomes less energy intensive, but the growth of the industrial production and the increasing household electricity demand induced higher energy consumption. The development of the nuclear power sector enhances these tendencies. The entire sector is under a reorganization process, with the final purpose to increase efficiency, privatizing the electrical distribution, thermal power plants, and some hydro and support services

    Science.gov (United States)

    Schwalenberg, T; Stolzenburg, J-U; Kriegel, C; Gonsior, A

    2012-01-01

    Sacral neuromodulation (SNM) in urology is employed to treat refractory lower urinary tract dysfunction as well as chronic pelvic pain. Electrical stimulation of the sacral afferents (S2 - S4) causes activation and conditioning of higher autonomic and somatic neural structures and thereby influences the efferents controlling the urinary bladder, the rectum and their related sphincter systems. It is therefore possible to treat overactivity as well as hypocontractility and functional bladder neck obstruction. SNM treatment is conducted biphasically. Initially, test electrodes are placed to evaluate changes in micturition and pain parameters. If, in this first phase - called peripheral nerve evaluation (PNE test) - sufficient improvements are observed, the patient progresses to phase two which involves implantation of the permanent electrodes and impulse generator system. In recent years, the "two stage approach" with initial implantation of the permanent electrodes has been favoured as it increases treatment success rates. Long-term success rates of SNM vary significantly in the literature (50 - 80 %) due to heterogeneous patient populations as well as improved surgical approaches. With the introduction of "tined lead electrodes" (2002), tissue damage is reduced to a minimum. Technical innovation, financial feasibility (reimbursed in Germany since 2004) and wider application, especially in otherwise therapy-refractory patients or complex dysfunctions of the pelvis, have established SNM as a potent treatment option in urology. © Georg Thieme Verlag KG Stuttgart · New York.

  7. Biofuel implementation in East Europe: Current status and future prospects

    International Nuclear Information System (INIS)

    Kondili, E.M.; Kaldellis, J.K.

    2007-01-01

    There is a continuously increasing interest concerning the biofuel implementation in Europe, mainly because of environmental protection and energy supply security reasons. In this context, the European Union (EU) strongly encourages the use of biofuels through a number of Directives. To that effect, EU members follow the Directives implementing various political, fiscal and technical measures and incentives. In the light of the potential created by the recently joined Eastern European countries, an increasing interest is shown in the whole biofuel supply chain within the EU. In parallel, the status of the Eastern European countries domestic market, as far as biofuels are concerned, is an interesting issue, since most of these countries present a significant potential, however still lagging in biofuel implementation. In the above context, the objective of the present work is to give a concise and up-to-date picture of the present status of biofuel implementation in East Europe. The work also aims at identifying the prospects of these countries as far as biofuels are concerned and their role in the EU framework as potential suppliers of a wider market. (author)

    Abstract Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin’s specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins. PMID:26155072

    The oriental liver fluke, Clonorchis sinensis, a pathogen causing clonorchiasis, is of major socio-economic importance in East Asia, including China, Korea and Vietnam. This parasite is now recognized as a biocarcinogen strongly linked to cholangiocarcinoma in humans. Here, we describe the status of clonorchiasis in China, where it has been estimated that more than 15 million patients are affected. This paper also summarizes the major advances in the field of clonorchiasis research during last decade, including diagnosis techniques, pathogenesis and genome/transcriptome/proteome studies in the last years. We strongly hope that our work can stimulate the governments of the countries or regions where clonorchiasis is endemic to pay more attention to this disease and establish related guidelines to prevent and control it. © The Author 2015.

    Bacterial wilt caused by plant pathogenic Ralstonia spp. is one of the most important diseases affecting the production of many important crops worldwide. In China, a large scientific community has been dedicated to studying bacterial wilt and its causative agent, Ralstonia pseudosolanacearum and R. solanacearum. Most of their work was published in Chinese, which has hindered international communication and collaboration in this field. In this review, we summarize the status of knowledge on geographical distribution, diversity, and host range of Ralstonia spp., as well as, the impact of bacterial wilt on important crops and disease control approaches, in China. We present areas of research and publications by Chinese scientists and propose the promotion of collaborative research within China and with the international community. PMID:28955350

    1993-03-01

    An overview of the space transportation aspects of the ESA (European Space Agency) programs as they result from history, present status, and decisions taken at the ministerial level conference in Granada, Spain is presented. The new factors taken into consideration for the long term plan proposed in Munich, Germany, the three strategic options for the reorientation of the ESA long term plan, and the essential elements of space transportation in the Granada long term plan in three areas of space activities, scientific, and commercial launches with expendable launch vehicles, manned flight and in-orbit infrastructure, and future transportation systems are outlined. The new ESA long term plan, in the field of space transportation systems, constitutes a reorientation of the initial program contemplated in previous councils at ministerial level. It aims at balancing the new economic situation with the new avenues of cooperation, and the outcome will be a new implementation of the space transportation systems policy.

    1994-09-01

    The Moving Pictures Experts Group (MPEG) of the International Standardization Organization has initiated a standardization effort, known as MPEG-4, addressing generic audiovisual coding at very low bit-rates (up to 64 kbits/s) with applications in videotelephony, mobile audiovisual communications, video database retrieval, computer games, video over Internet, remote sensing, etc. This paper gives a survey of the status of MPEG-4, including its planned schedule, and initial ideas about requirements and applications. A significant part of this paper is summarizing an incomplete draft version of a `requirements document' which presents specifications of desirable features on the video, audio, and system level of the forthcoming standard. Very low bit-rate coding algorithms are not described, because no endorsement of any particular algorithm, or class of algorithms, has yet been made by MPEG-4, and several seminars held concurrently with MPEG-4 meetings have not so far provided evidence that such high performance coding schemes are achievable.

    2003-01-01

    Macromolecular contrast media (MMCM) encompass a new class of diagnostic drugs that can be applied with dynamic MRI to extract both physiologic and morphologic information in breast lesions. Kinetic analysis of dynamic MMCM-enhanced MR data in breast tumor patients provides useful estimates of tumor blood volume and microvascular permeability, typically increased in cancer. These tumor characteristics can be applied to differentiate benign from malignant lesions, to define the angiogenesis status of cancers, and to monitor tumor response to therapy. The most immediate challenge to the development of MMCM-enhanced mammography is the identification of those candidate compounds that demonstrate the requisite long intravascular distribution and have the high tolerance necessary for clinical use. Potential mammographic applications and limitations of various MMCM, defined by either experimental animal testing or clinical testing in patients, are reviewed in this article. (orig.)

    The HappyFace Project is a meta-monitoring tool, which is allow to monitor the Grid sites of the Worldwide LHC Computing Grid (WLCG). It can also be used for any (complex) computing system, e.g. local or distributed computing resources. HappyFace provides fast access to all relevant monitoring sites and gets a complete overview about the status of all available sites on one page. It has an automatic querying system, a lot of testing modules can be plugged in and also the ability to design and add new modules is available. The project had been written in Python and PHP, but in the 3rd version of HappyFace the source code is fully migrated to Python and the web output uses only HTML templates, which makes it simpler.

  2. Private protected areas in Australia: current status and future directions

    Full Text Available Despite the recognised importance of private land for biodiversity conservation, there has been little research into systems of private protected areas at a country-wide level. Here I look at definitions, legislation, ownership, management approaches and effectiveness, distribution and incentives provided to private protected areas in Australia. The term ‘private protected areas’, although increasingly used, still suffers from a lack of a clear and concise definition in Australia. Australian states and territories have legislation enabling the application of conservation covenants over private land; covenants being the primary mechanism to secure conservation intent on the title of the land in perpetuity. If considering all ‘in perpetuity’ conservation covenants under a dedicated program to be private protected areas and land owned by non-government organisations and managed for the purpose of biodiversity conservation, there were approximately 5,000 terrestrial properties that could be considered private protected areas in Australia covering 8,913,000 ha as at September 2013. This comprises almost 4,900 conservation covenants covering over 4,450,000 ha and approximately 140 properties owned by private land trusts covering approximately 4,594,120 ha. Most conservation covenanting programs now seek to complement the comprehensiveness, adequacy and representativeness of the public reserve system, either stating so explicitly or by aiming to protect the highest priority ecosystems on private land. There are a range of incentives offered for private land conservation and requirements of owners of private protected areas to report on their activities vary in Australia. However, there are a number of key policy challenges that need to be addressed if private protected areas are to achieve their full potential in Australia, including managing broad-scale ecosystem processes, protection and tenure reform, improved financial incentives, and

    Full Text Available The article analyzed the process of reforming the system of accounting and reporting in Ukraine in accordance with International Financial Reporting Standards. The main results of the tasks of the Strategy of application IFRS in Ukraine approved by the Cabinet of Ministers of Ukraine in 2007 are identified. The results of analysis showed that only 1% of the total number of enterprises form the financial statements in accordance with IFRS, the others apply national standards of accounting. The proportion of small enterprises is 95% that do not have the financial capacity, qualified staff and the necessary motivation for the formation of financial statements in accordance with IFRS. As a result, one of the main objectives of the reform of the accounting and reporting is to improve the legislation on accounting for small enterprises and develop national accounting standards of the simplified procedure for accounting of assets, liabilities, equity and financial results of the calculation for small enterprises.

    2014-10-01

    Interest for nuclear energy had resurgence since the beginning of the new century. This was a consequence of the new world conditions and needs: increasing energy demands (mainly from developing countries), awareness of the importance of energetic security and the necessity of limiting carbon emissions. In this nuclear boom, Small Modular Reactors (SMRs) develop and start to consolidate as a viable option for the present energy market. Their modular characteristics, lower initial capital cost, passive safety features and their niche applications, situate them as a technology with various advantages. The following study will present and analysis that will help to comprehend the SMRs present status. Information will show planned reactors, reactors in construction and in operation, advantages and challenges of their implementation, relevant economic aspects and important licensing factors that need to be highlighted. The analysis showed that the SMR technology is still in an initial stage that could reach and important development point in the next ten years. In this period, many of the reactors that are in design stage or that are through their licensing process might be constructed and could be getting ready for a commercial status. On the other hand, it has been observed that there are two main economic factors that need to be considered for any SMRs implementation project. First, the costs (initial, operation, maintenance, fuel and decommissioning) and second their possible niche market applications. Additionally, it has been noted that the licensing process is one of the greatest challenges for SMR general development. Licensing is mainly related to topic such as Emergency Planning Zone, first-of-a-kind engineering, passive safety features, proliferation resistance, multiple module designs and staffing. Previous information will serve as a base for carrying out a feasibility assessment analysis for SMR in Mexico. This part will be the last section of the project

  5. Current status of cadmium as an environmental health problem

    International Nuclear Information System (INIS)

    Jaerup, Lars; Akesson, Agneta

    2009-01-01

    Cadmium is a toxic metal occurring in the environment naturally and as a pollutant emanating from industrial and agricultural sources. Food is the main source of cadmium intake in the non-smoking population. The bioavailability, retention and toxicity are affected by several factors including nutritional status such as low iron status. Cadmium is efficiently retained in the kidney (half-time 10-30 years) and the concentration is proportional to that in urine (U-Cd). Cadmium is nephrotoxic, initially causing kidney tubular damage. Cadmium can also cause bone damage, either via a direct effect on bone tissue or indirectly as a result of renal dysfunction. After prolonged and/or high exposure the tubular injury may progress to glomerular damage with decreased glomerular filtration rate, and eventually to renal failure. Furthermore, recent data also suggest increased cancer risks and increased mortality in environmentally exposed populations. Dose-response assessment using a variety of early markers of kidney damage has identified U-Cd points of departure for early kidney effects between 0.5 and 3 μg Cd/g creatinine, similar to the points of departure for effects on bone. It can be anticipated that a considerable proportion of the non-smoking adult population has urinary cadmium concentrations of 0.5 μg/g creatinine or higher in non-exposed areas. For smokers this proportion is considerably higher. This implies no margin of safety between the point of departure and the exposure levels in the general population. Therefore, measures should be put in place to reduce exposure to a minimum, and the tolerably daily intake should be set in accordance with recent findings.

    2014-08-25

    Oral transmucosal drug delivery (OTDD) dosage forms have been available since the 1980s. In contrast to the number of actives currently delivered locally to the oral cavity, the number delivered as buccal or sublingual formulations remains relatively low. This is surprising in view of the advantages associated with OTDD, compared with conventional oral drug delivery. This review examines a number of aspects related to OTDD including the anatomy of the oral cavity, models currently used to study OTDD, as well as commercially available formulations and emerging technologies. The limitations of current methodologies to study OTDD are considered as well as recent publications and new approaches which have advanced our understanding of this route of drug delivery.

    Full Text Available Among children, rotaviruses are the most common cause of severe gastroenteritis worldwide and of diarrheal deaths in developing countries. Current vaccines (e.g., Rotarix, GlaxoSmithKline Biologicals; RotaTeq, Merck and Company effectively reduce rotaviral gastroenteritis, emergency department visits, and hospitalizations. The tremendous burden of rotavirus-related diarrhea in children across the world continues to drive the remarkable pace of vaccine development. This review assesses the global epidemiological and economic burden of rotavirus diseases, summarizes the relevant principles of the development of rotavirus vaccines, and presents data on the efficacy and effectiveness of currently licensed vaccines in both developed and developing countries.

    2016-01-01

    ABSTRACT Little is known about the current health status of US metal and nonmetal (MNM) miners, in part because no health surveillance systems exist for this population. The National Institute for Occupational Safety and Health (NIOSH) is developing a program to characterize burden of disease among MNM miners. This report discusses current knowledge and potential data sources of MNM miner health. Recent national surveys were analyzed, and literature specific to MNM miner health status was reviewed. No robust estimates of disease prevalence were identified, and national surveys did not provide information specific to MNM miners. Because substantial gaps exist in the understanding of MNM miners' current health status, NIOSH plans to develop a health surveillance program for this population to guide intervention efforts to reduce occupational and personal risks for chronic illness.

    The purpose of this investigation is to determine the proportion of sports medicine studies that are labeled as Level I Evidence in 5 journals and compare the quality of surgical and nonsurgical studies using simple quality assessment tools (Consolidated Standards of Reporting Trials [CONSORT] and Jadad). By use of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines over the prior 2 years in the top 5 (citation and impact factor based) sports medicine journals, only Level I Evidence studies were eligible for inclusion and were analyzed. All study types (therapeutic, prognostic, diagnostic, and economic) were analyzed. Study quality was assessed with the level of evidence, Jadad score, and CONSORT 2010 guidelines. Study demographic data were compared among journals and between surgical and nonsurgical studies by use of χ(2), 1-way analysis of variance, and 2-sample Z tests. We analyzed 190 Level I Evidence studies (10% of eligible studies) (119 randomized controlled trials [RCTs]). Therapeutic, nonsurgical, single-center studies from the United States were the most common studies published. Sixty-two percent of studies reported a financial conflict of interest. The knee was the most common body part studied, and track-and-field/endurance sports were the most common sports analyzed. Significant differences (P journals reviewed. Overall, the Jadad and CONSORT scores were 2.71 and 77%, respectively. No differences (P > .05) were shown among journals based on the proportion of Level I studies or appropriate randomization. Significant strengths and limitations of RCTs were identified. This study showed that Level I Evidence and RCTs comprise 10% and 6% of contemporary sports medicine literature, respectively. Therapeutic, nonsurgical, single-center studies are the most common publications with Level I Evidence. Significant differences across sports medicine journals were found in study quality. Surgical studies appropriately described

  2. Brain perfusion CT in acute stroke: current status

    Energy Technology Data Exchange (ETDEWEB)

    Koenig, Matthias E-mail: matthias.koenig@ruhr-uni-bochum.de

    2003-03-01

    Dynamic perfusion CT has become a widely accepted imaging modality for the diagnostic workup of acute stroke patients. Although compared with standard spiral CT the use of multislice CT has broadened the range from which perfusion data may be derived in a single scan run. The advent of multidetector row technology has not really overcome the limited 3D capability of this technique. Multidetector CT angiography (CTA) of the cerebral arteries may in part compensate for this by providing additional information about the cerebrovascular status. This article describes the basics of cerebral contrast bolus scanning with a special focus on optimization of contrast/noise in order to ensure high quality perfusion maps. Dedicated scan protocols including low tube voltage (80 kV) as well as the use of highly concentrated contrast media are amongst the requirements to achieve optimum contrast signal from the short bolus passage through the brain. Advanced pre and postprocessing algorithms may help reduce the noise level, which may become critical in unconscious stroke victims. Two theoretical concepts have been described for the calculation of tissue perfusion from contrast bolus studies, both of which can be equally employed for brain perfusion imaging. For each perfusion model there are some profound limitations regarding the validity of perfusion values derived from ischemic brain areas. This makes the use of absolute quantitative cerebral blood flow (CBF) values for the discrimination of the infarct core from periinfarct ischemia questionable. Multiparameter imaging using maps of CBF, cerebral blood volume (CBV), and a time parameter of the local bolus transit enables analyzing of the cerebral perfusion status in detail. Perfusion CT exceeds plain CT in depicting cerebral hypoperfusion at its earliest stage yielding a sensitivity of about 90% for the detection of embolic and hemodynamic lesions within cerebral hemispheres. Qualitative assessment of brain perfusion can be

    2017-12-01

    While conventional laparoscopy is the gold standard for almost all bariatric procedures, robotic assistance holds promise for facilitating complex surgeries and improving clinical outcomes. Since the report of the first robotic-assisted bariatric procedure in 1999, numerous publications, including those reporting comparative trials and meta-analyses across bariatric procedures with a focus on robotic assistance, can be found. This article reviews the current literature and portrays the perspectives of robotic bariatric surgery. While there are substantial reports on robotic bariatric surgery currently in publication, most studies suffer from low levels of evidence. As such, although robotics technology is without a doubt superior to conventional laparoscopy, the precise role of robotics in bariatric surgery is not yet clear.

    Full text: Poultry biodiversity conservation is a great challenge for many countries. Within the last several years, the number of endangered local breeds has increased, leading to a considerable loss of genetic resources. A similar trend was observed among the poultry breeds, including chicken, local turkey and goose breeds/lines established in Bulgaria, part of which is definitely lost. Currently these breeds/lines are at risk and/or threatened with extinction. The information obtained by phenotypic characterization of these breeds is the first step for planning the management of poultry genetic resources through setting up improved selection schemes and conservation strategies. In this paper, we reviewed the current state of knowledge regarding the morphological and phenotypic diversity of local poultry breeds and some old productive poultry lines in Bulgaria. (author)

    LHCf is an experiment currently installed at CERN at the LHC complex. It consists of two small calorimeters each one placed 140 meters away from the ATLAS interaction point. Their purpose is to study forward production of neutral particles in proton-proton collisions at extremely low angles. The results will provide invaluable inputs to the many air-shower Monte Carlo codes currently used for modeling cosmic rays interactions in the Earth atmosphere. Depending on machine start up, data will be taken from 900 GeV in the centre of mass up to 14 TeV (laboratory equivalent collision energy of 1017eV), thus covering an energy range up to and beyond the “knee” of the cosmic ray spectrum.

    Full Text Available Free-living amoebae belonging to the genus Acanthamoeba have an environmental distribution. Amoebic keratitis due to these protozoan parasites continue to rise in Iran and worldwide. In Iran, there are various researches regarding both morphological and molecular identification of Acanthamoeba spp. in environmental and clinical samples. However, there is no thorough review about Acanthamoeba genotypes and their distribution in environmental sources such as water, dust and biofilm in Iran. Besides, according to increasing cases of Amoebic keratitis in the region awareness regarding the pathogenic potential of these sight-threatening amoebae is of utmost importance.We conducted a thorough review based on the database sources such as MEDLINE, PubMed and Google scholar. No restrictions were placed on study date, study design or language of publication. We searched all valuable and relevant information considering the occurrence of the Acanthamoeba in both environmental and clinical samples.According to our thorough review Acanthamoeba belonging to T4 genotype is the most prevalent type strain in environmental and clinical samples in several regions in Iran and worldwide, however, there are reports regarding Acanthamoeba belonging to other genotypes such as T2, T3, T5, T6 and T11 and the mentioned point could leads us to more researches with the goal of presenting the real genotype dominance of Acanthamoeba and related disease in the country.Overall, the present review will focus on present status of genotypes of Acanthamoeba in Iran during recent years.

    To investigate the status and treatment of superficial pharyngeal squamous cell carcinoma in Japan. We analyzed all cases diagnosed between 2011 and 2013, as recorded in the national database of hospital-based cancer registries. We extracted data on patient sex, age, tumor locations, histology, presentation routes, initial treatments, and TNM stages. Additionally, we compared the characteristics of pharyngeal carcinoma to those of esophageal cancer. A total of 16,521 oropharyngeal and hypopharyngeal cancers from 409 institutions were included. Diagnosis of Tis tumors was infrequent, and both cancers were likely to be diagnosed at an advanced stage (n = 866, 5.3%). Tis diseases were the most commonly detected during follow-up examinations for other diseases (n = 608, 70%). While more oropharyngeal Tis patients were men compared to T1-4 patients (88 vs 82%, respectively), hypopharyngeal cancer patients comprised an equally high proportion of men (94 vs 92%, respectively). The most common location of oropharyngeal Tis tumors was the posterior wall (32%), whereas T1-4 tumors were most commonly found on the lateral wall (36%). In hypopharyngeal cancer, both Tis and T1-4 were most commonly located in the pyriform sinus (62%). The proportion of Tis tumors diagnosed at individual institutions showed a positive correlation with the number of endoscopic treatments (r = 0.32, P squamous cell carcinoma patients in Japan. Further improvements in early diagnosis and standardized treatments are warranted.

    In this paper, the development of nuclear power in China, its status of operating nuclear power plants and progress of on-going NPP projects are described. With the arising of spent fuel from NPPs, a national policy of a closed nuclear fuel cycle has been determined. Following storage at reactor sites for at least 5 years (generally maximum 10 years), spent fuel will be transferred to an away-from-reactor pool type centralized storage facility. Adjacent to the storage facility, a multi-purpose reprocessing pilot plant will be set up by the end of this century. An industrial scale reprocessing plant would be succeeded around the year 2020. China's spent fuel management activities include at-reactor storage, transportation, away-from-reactor storage and reprocessing. Relatively detailed description of the work done up to now on spent fuel management and plans for the future are described. It should be noted that activities related to the management of high level radioactive waste are not included here. (author)

  10. Prostate cancer chemoprevention: Current status and future prospects

    2007-01-01

    Chemoprevention is a strategy that aims to reduce the incidence and burden of cancer through the development of agents to prevent, reverse or delay the carcinogenic process. Prostate cancer is a suitable target for prevention because it has a high incidence and prevalence, as well as a long latency and disease-related mortality, and furthermore it is a disease in which lifestyle and environmental factors may play critical roles. The development of chemoprevention strategies against prostate cancer will have a huge impact, both medically and economically. Large-scale clinical trials suggest that some agents such as selenium, lycopene, soy, green tea, vitamins D and E, anti-inflammatory and inhibitors of 5α-reductase are effective in preventing prostate cancer. Although each agent has the potential to affect the natural history of the disease, it is important to develop strategies to strategically proceed for the design and selection of test agents in order to demonstrate clinical benefit with the minimum of adverse effects. Appropriate selection of agent(s), disease stage, trial design and endpoints is critical in selecting the most promising regimens to accomplish these goals. This review highlights the present status of prostate cancer chemoprevention and discusses future prospects for chemopreventive strategies that are safe and clinically beneficial

    1996-01-01

    After the Chernobyl accident of April 26, 1986, many contradictory decisions were taken concerning the Chernobyl nuclear power plant (NPP) future. The principal source of contradictions was a deadline for a final shutdown of the Chernobyl NPP units. Alterations in a political and socioeconomic environment resulted in the latest decision of the Ukrainian Authorities about 2000 as a deadline for a beginning of the Chernobyl NPP decommissioning. The date seems a sound compromise among the parties concerned. However, in order to meet the data a lot of work should be done. First of all, a decommissioning strategy has to be established. The problem is complicated due to both site-specific aspects and an absence of proven solutions for the RBMK-type reactor decommissioning. In the paper the problem of decommissioning option selection is considered taking into account an influence of the following factors: relevant legislative and regulatory requirements; resources required to carry out decommissioning (man-power, equipment, technologies, waste management infrastructure, etc.); radiological and physical status of the plant, including structural integrity and predictable age and weather effects; impact of planned activities at the destroyed unit 4 and within the 30-km exclusion zone of the Chernobyl NPP; planed use of the site; socio-economic considerations

    The Low Frequency All Sky Monitor (LoFASM) is a distributed array of cross-dipole antennas that are sensitive to radio frequencies from 10 to 88 MHz. LoFASM consists of antennas and front end electronics that were originally developed for the Long Wavelength Array by the U.S. Naval Research Lab, the University of New Mexico, Virginia Tech, and the Jet Propulsion Laboratory. LoFASM, funded by the U.S. Department of Defense, will initially consist of 4 stations, each consisting of 12 dual- polarization dipole antenna stands. The primary science goals of LoFASM will be the detection and study of low-frequency radio transients, a high priority science goal as deemed by the National Research Council’s ASTRO2010 decadal survey. The data acquisition system for the LoFASM antenna array uses Field Programmable Gate Array (FPGA) technology to implement a real time full Stokes spectrometer and data recorder. This poster presents an overview of the LoFASM Radio Telescope as well as the status of data analysis of initial commissioning observations.

    The current SMA receiver systems were designed in the mid-1990s and have been operating for more than fifteen years. With regular upgrades to receivers, deployment of the SWARM correlator, expansion of the IF signal transport bandwidth via improvements to the analog IF signal processing hardware, and many other enhancements, the SMA currently greatly outperforms its original specifications in terms of sensitivity, instantaneous bandwidth, and availability of observing modes such as full-Stokes polarization and dual frequency operation.We have recently started to implement a three-year instrument upgrade plan, which we are calling the wSMA. The wSMA will offer even wider bandwidth operation than the current SMA and improved sensitivity. The major subsystems that will form the wSMA include significantly improved, dual polarization receiver cartridges housed in a new cryostat; local oscillator units incorporating modern mm-wave technology; an upgraded signal transmission system; and a further expansion of the SWARM correlator. The cryostat will be cooled by a low-maintenance pulse-tube cryocooler. Two dual-polarization receiver cartridges will cover approximately the same sky frequencies as the current receiver sets; the low-band receiver will be fed by an LO unit covering 210-270 GHz, and the high-band receiver will be fed by an LO covering 280-360 GHz. With a receiver IF band of 4-20 GHz, this will enable continuous sky frequency coverage from 190 GHz to 380 GHz.Details of the upgrade plans will be presented together with a discussion of scientific opportunities afforded by this upgrade, which, once implemented, will enable the SMA to continue to produce the highest quality science throughout the next decade.

    Clark, D.E.; Colombo, P.; Sailor, V.L.

    1982-01-01

    The adoption of improved waste segregation practices by waste generators and burial sites will result in the improved disposal of low-level wastes (LLW) in the future. Many of the problems connected with this disposal mode are directly attributable to or aggravated by the indiscriminate mixing of various waste types in burial trenches. Thus, subsidence effects, contact with ground fluids, movement of radioactivity in the vapor phase, migration of radionuclides due to the presence of chelating agents or products of biological degradation, deleterious chemical reactions, and other problems have occurred. Regulations are currently being promulgated which will require waste segregation to a high degree at LLW burial sites. The state-of-the-art of LLW segregation technology and current practices in the USA have been surveyed at representative facilities. Favorable experience has been reported at various sites following the application of segregation controls. This paper reports on the state-of-the-art survey and addresses current and projected LLW segregation practices and their relationship to other waste management activities

    2016-04-01

    Full Text Available Korea has been operating groundwater monitoring systems since 1996 as the Groundwater Act enacted in 1994 enforces nationwide monitoring. Currently, there are six main groundwater monitoring networks operated by different government ministries with different purposes: National Groundwater Monitoring Network (NGMN, Groundwater Quality Monitoring Network (GQMN, Seawater Intrusion Monitoring Network (SIMN, Rural Groundwater Monitoring Network (RGMN, Subsidiary Groundwater Monitoring Network (SGMN, and Drinking Water Monitoring Network (DWMN. The Networks have a total of over 3500 monitoring wells and the majority of them are now equipped with automatic data loggers and remote terminal units. Most of the monitoring data are available to the public through internet websites. These Networks have provided scientific data for designing groundwater management plans and contributed to securing the groundwater resource particularly for recent prolonged drought seasons. Each Network, however, utilizes its own well-specifications, probes, and telecommunication protocols with minimal communication with other Networks, and thus duplicate installations of monitoring wells are not uncommon among different Networks. This mini-review introduces the current regulations and the Groundwater Monitoring Networks operated in Korea and provides some suggestions to improve the sustainability of the current groundwater monitoring system in Korea.

    Musbahi, Omar; Aydin, Abdullatif; Al Omran, Yasser; Skilbeck, Christopher James; Ahmed, Kamran

    Otolaryngology is a highly technical and demanding specialty and the requirements for surgical trainees to acquire proficiency remains challenging. Simulation has been purported to be an effective tool in assisting with this. The aim of this systematic review is to identify the available otolaryngology simulators, their status of validation, and evaluation the level of evidence behind each training model and thereby establish a level of recommendation. PubMed, ERIC, and Google Scholar databases were searched for articles that described otolaryngology simulators or training models between 1980 and April 2016. Any validation studies for simulators were also retrieved. Titles and abstracts were screened for relevance using the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Level of evidence (LoE) and Level of recommendation (LoR) was awarded to each study and model, respectively. A total of 70 studies were identified describing 64 simulators. Out of these, at least 54 simulators had 1 validation study. Simulators for the ear and temporal bone surgery were the most common (n = 32), followed by laryngeal and throat (n = 20) and endoscopic sinus surgery (n = 12). Face validity was evaluated by 29 studies, 20 attempted to show construct, 20 assessed content, 20 transfer, and only 2 assessed concurrent validity. Of the validation assessments, 2 were classified as Level 1b, 10 Level 2a, and 48 Level 2b. No simulators received the highest LoR, but 8 simulators received a LoR of 2. Despite the lack of evidence in outcome studies and limited number of high-validity otolaryngology simulators, the role of simulation continues to grow across surgical specialties Hence, it is imperative that the simulators are of high validity and construct for trainees to practice and rehearse surgical skills to develop confidence.

    The number of assisted reproductive technology (ART) clinics, ART cycles, clinical pregnancy rate (CPR), and number of newborns conceived using ART have steadily increased in South Korea. This aim of this study was to describe the status of ART in South Korea between January 1 and December 31, 2011. A localized online survey was created and sent to all available ART centers via email in 2015. Fresh embryo transfer (FET) cases were categorized depending on whether standard in vitro fertilization, intracytoplasmic sperm injection (ICSI), or half-ICSI procedures were used. Thawed embryo transfer (TET) and other related procedures were surveyed. Data from 36,990 ART procedures were provided by 74 clinics. Of the 30,410 cycles in which oocytes were retrieved, a complete transfer was performed in 91.0% (n=27,683). In addition, 9,197 cycles were confirmed to be clinical pregnancies in the FET cycles, representing a pregnancy rate of 30.2% per oocyte pick-up and 33.2% per ET. The most common number of embryos transferred in the FET procedures was three (38.1%), followed by two (34.7%) and one (14.3%). Of the 8,826 TET cycles, 3,137 clinical pregnancies (31.1%) were confirmed by ultrasonography. While the overall clinical pregnancy rate for the TET cycles performed was lower than the rate reported in 2010 (31.1% vs. 35.4%), the overall CPR for the FET cycles was higher than in 2010 (33.2% in 2011 and 32.9% in 2010). The most common number of embryos transferred in FET cycles was three, as was the case in 2010.

    2010-11-01

    Human cytomegalovirus (HCMV) is ubiquitous in all populations, and is the most commonly recognized cause of congenital viral infection in developed countries. On the basis of the economic costs saved and the improvement in quality of life that could potentially be conferred by a successful vaccine for prevention of congenital HCMV infection, the Institute of Medicine has identified HCMV vaccine development as a major public health priority. An effective vaccine could potentially also be beneficial in preventing or ameliorating HCMV disease in immunocompromised individuals. Although there are no licensed HCMV vaccines currently available, enormous progress has been made in the last decade, as evidenced by the recently reported results of a Phase II trial of a glycoprotein B vaccine for the prevention of HCMV infection in seronegative women of childbearing age. HCMV vaccines currently in clinical trials include: glycoprotein B subunit vaccines; alphavirus replicon particle vaccines; DNA vaccines; and live-attenuated vaccines. A variety of vaccine strategies are also being examined in preclinical systems and animal models of infection. These include: recombinant vesicular stomatitis virus vaccines; recombinant modified vaccinia virus Ankara; replication-deficient adenovirus-vectored vaccines; and recombinant live-attenuated virus vaccines generated by mutagenesis of cloned rodent CMV genomes maintained as bacterial artificial chromosomes in Escherichia coli. In this article, we provide an overview of the current state of clinical trials and preclinical development of vaccines against HCMV, with an emphasis on studies that have been conducted in the past 5 years. We also summarize a number of recent advances in the study of the biology of HCMV, particularly with respect to epithelial and endothelial cell entry of the virus, which have implications for future vaccine design.

    This article reviews current knowledge about leishmaniases in Ecuador, proceeding from 1920, when the first human case was described, to the present, mainly focusing on the recent research events published. Regarding basic situations, it appears that 23 of Ecuador's 24 provinces have leishmaniasis-case reports. The disease is one of the mandatory notification infectious diseases in the country since 2005. All the 21,305 cases notified to the Ministry of Public Health, during the period from 2001 through 2014, were said to involve different clinical features of cutaneous leishmaniasis (CL) but not visceral (VL). Eight Leishmania species, L. (Viannia) guyanensis, L. (V.) panamensis, L. (V.) braziliensis, L. (Leishmania) mexicana, L. (L.) amazonensis, L. (L.) major-like, L. (V.) naiffiand L. (V.) lainsoni were characterized. The last two species were most recently reported from the Ecuadorian Amazon regions. Of the 73 Ecuadorian Lutzomyia species (43 man-biting species) recorded, only four, Lu. trapidoi, Lu. gomezi, Lu. ayacuchensis, and Lu. tortura were incriminated as vectors of the Leishmania parasites. Current knowledge on the reservoir hosts of Leishmania in Ecuador is extremely poor. Recently, in Ecuador different kinds of molecular techniques were developed for diagnosis and mass screening of the disease, employing various materials derived from patients and sand fly vectors. These are PCR-RFLP, colorimetric FTA-LAMP etc. Brief comments and recommendations were also given, for future research and control of leishmaniases in Ecuador. Copyright © 2016 Elsevier B.V.

    Korea has decided to test Helium Cooled Ceramic Reflector (HCCR) Test Blanket Module (TBM) in ITER and design of the TBM with its ancillary systems, i.e. Test Blanket System (TBS), is under progress. Since the TBM is operated at elevated temperature with high heat load, safety consideration is essential in design procedure. In this paper, preliminary accident analysis results for the current HCCR TBS design on selected scenarios are presented as an important part of safety assessments. To simulate transient thermo-hydraulic behavior, GAMMA-FR code which has been developed in Korea for fusion applications was used. The main cooling and tritium extraction circuit systems, as well as the TBM, were simulated and the main components in the TBS were modeled as the associated heat structures. The important accident scenarios were produced and summarized in the paper considering the HCCR TBS design and ITER conditions, which cover in-vessel Loss Of Coolant Accident (LOCA), in-box LOCA, ex-vessel LOCA, Loss Of Flow Accident (LOFA), Loss Of Heat Sink Accident (LOHSA) and purge pipe rupture case. The accident analysis based on the selected scenarios was performed and it was found that the current design of the HCCR TBS meets the thermo-hydraulic safety requirements.

    2015-01-01

    Yellow fever 17D vaccine is one of the oldest live-attenuated vaccines in current use that is recognized historically for its immunogenic and safe properties. These unique properties of 17D are presently exploited in rationally designed recombinant vaccines targeting not only flaviviral antigens but also other pathogens of public health concern. Several candidate vaccines based on 17D have advanced to human trials, and a chimeric recombinant Japanese encephalitis vaccine utilizing the 17D backbone has been licensed. The mechanism(s) of attenuation for 17D are poorly understood; however, recent insights from large in silico studies have indicated particular host genetic determinants contributing to the immune response to the vaccine, which presumably influences the considerable durability of protection, now in many cases considered to be lifelong. The very rare occurrence of severe adverse events for 17D is discussed, including a recent fatal case of vaccine-associated viscerotropic disease.

    2017-08-01

    Borrowed from organizational psychology, the concept of transformational leadership has now been applied to a sport context for a decade. Our review covers and critically discusses empirical articles published on this growing topic. However, because the majority of studies used cross-sectional designs and single-source questionnaires to tap what has been a fuzzy construct, current theoretical and methodological issues impede understanding of whether transformational leadership matters for sport outcomes. To make a difference to applied practice and policy, the transformational leadership construct requires a refined definition and stronger empirical tests allowing for robust causal inference. We highlight avenues for advancing research on transformational leadership in the sport context. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    Vythilingam, I; Wong, M L; Wan-Yussof, W S

    2018-01-01

    Plasmodium knowlesi a simian malaria parasite is currently affecting humans in Southeast Asia. Malaysia has reported the most number of cases and P. knowlesi is the predominant species occurring in humans. The vectors of P. knowlesi belong to the Leucosphyrus group of Anopheles mosquitoes. These are generally described as forest-dwelling mosquitoes. With deforestation and changes in land-use, some species have become predominant in farms and villages. However, knowledge on the distribution of these vectors in the country is sparse. From a public health point of view it is important to know the vectors, so that risk factors towards knowlesi malaria can be identified and control measures instituted where possible. Here, we review what is known about the knowlesi malaria vectors and ascertain the gaps in knowledge, so that future studies could concentrate on this paucity of data in-order to address this zoonotic problem.

    2015-07-01

    Full Text Available This paper presents a review of the rationale for the in vitro mineralization process, preparation methods, and clinical applications of mineralized collagen. The rationale for natural mineralized collagen and the related mineralization process has been investigated for decades. Based on the understanding of natural mineralized collagen and its formation process, many attempts have been made to prepare biomimetic materials that resemble natural mineralized collagen in both composition and structure. To date, a number of bone substitute materials have been developed based on the principles of mineralized collagen, and some of them have been commercialized and approved by regulatory agencies. The clinical outcomes of mineralized collagen are of significance to advance the evaluation and improvement of related medical device products. Some representative clinical cases have been reported, and there are more clinical applications and long-term follow-ups that currently being performed by many research groups.

  3. Current Status of Mycotoxin Analysis: A Critical Review.

    Science.gov (United States)

    Shephard, Gordon S

    2016-07-01

    It is over 50 years since the discovery of aflatoxins focused the attention of food safety specialists on fungal toxins in the feed and food supply. Since then, analysis of this important group of natural contaminants has advanced in parallel with general developments in analytical science, and current MS methods are capable of simultaneously analyzing hundreds of compounds, including mycotoxins, pesticides, and drugs. This profusion of data may advance our understanding of human exposure, yet constitutes an interpretive challenge to toxicologists and food safety regulators. Despite these advances in analytical science, the basic problem of the extreme heterogeneity of mycotoxin contamination, although now well understood, cannot be circumvented. The real health challenges posed by mycotoxin exposure occur in the developing world, especially among small-scale and subsistence farmers. Addressing these problems requires innovative approaches in which analytical science must also play a role in providing suitable out-of-laboratory analytical techniques.

  4. Treatment of sepsis: current status of clinical immunotherapy.

    2012-02-03

    While antibiotics address the root cause of sepsis--that of pathogen infection--they fail to provide an adequate cure for the condition. Currently, 30% to 50% of septic patients die, and this figure is likely to increase in line with the proliferation of multi-drug resistant bacteria. With an increased understanding of the immune response, it has been proposed that modulation of this defence mechanism offers the best hope of cure. Many entry-points in the immune system have been identified and targeted therapies have been developed,but why are these not in routine clinical practice? This review examines the latest evidence for the use of immuno-modulating drugs, obtained from human clinical trials. We discuss cytokine-based therapies, steroids and anti-coagulants. Finally, consideration is given as to why successful therapies in the laboratory, and in vivo models, do not automatically translate into clinical benefit

    2017-01-01

    Full Text Available Lectins are carbohydrate recognizing proteins originating from diverse origins in nature, including animals, plants, viruses, bacteria and fungus. Due to their exceptional glycan recognition property, they have found many applications in analytical chemistry, biotechnology and surface chemistry. This manuscript explores the current use of lectins for cancer diagnosis and therapy. Moreover, novel drug delivery strategies aiming at improving lectin’s stability, reducing their undesired toxicity and controlling their non-specific binding interactions are discussed. We also explore the nanotechnology application of lectins for cancer targeting and imaging. Although many investigations are being conducted in the field of lectinology, there is still a limited clinical translation of the major findings reported due to lectins stability and toxicity concerns. Therefore, new investigations of safe and effective drug delivery system strategies for lectins are warranted in order to take full advantage of these proteins.

    The NNCA uses secure remote monitoring systems, both for reporting to the IAEA and for the bilateral cooperation with Sandia (SNL) and Idaho National Laboratory (INL). The NNCA system architecture has changed from a system using a Central Monitoring Station at the former TCNC, to direct internet reporting on a simultaneous basis to the IAEA and the NNCA. The NNCA reporting system is applied at 16 power reactors. This experience provides the basis for a detailed cost analysis and evaluation of trouble-shooting experience. Progress in establishing remote monitoring cooperation between the Korea Atomic Energy Research Institute's new Advanced Spent Fuel Conditioning Process Facility (ACPE) and Sandia is a precondition for regional cooperation. The ACPF system, which is currently in final testing, features network configuration and equipment that differ from safeguards standards for reasons of cost and flexibility. This allows the NNCA to take advantage of rapidly developing technologies at lower cost. (author)

    2016-09-29

    Metagenomic approaches are now commonly used in microbial ecology to study microbial communities in more detail, including many strains that cannot be cultivated in the laboratory. Bioinformatic analyses make it possible to mine huge metagenomic datasets and discover general patterns that govern microbial ecosystems. However, the findings of typical metagenomic and bioinformatic analyses still do not completely describe the ecology and evolution of microbes in their environments. Most analyses still depend on straightforward sequence similarity searches against reference databases. We herein review the current state of metagenomics and bioinformatics in microbial ecology and discuss future directions for the field. New techniques will allow us to go beyond routine analyses and broaden our knowledge of microbial ecosystems. We need to enrich reference databases, promote platforms that enable meta- or comprehensive analyses of diverse metagenomic datasets, devise methods that utilize long-read sequence information, and develop more powerful bioinformatic methods to analyze data from diverse perspectives.

    2013-01-01

    Full Text Available Advances in fermentation technologies have resulted in the production of increased yields of proteins of economic, biopharmaceutical, and medicinal importance. Consequently, there is an absolute requirement for the development of rapid, cost-effective methodologies which facilitate the purification of such products in the absence of contaminants, such as superfluous proteins and endotoxins. Here, we provide a comprehensive overview of a selection of key purification methodologies currently being applied in both academic and industrial settings and discuss how innovative and effective protocols such as aqueous two-phase partitioning, membrane chromatography, and high-performance tangential flow filtration may be applied independently of or in conjunction with more traditional protocols for downstream processing applications.

    To describe the current indications, techniques and results of sacral root stimulation in patients with spinal cord lesions as a treatment for patients with high pressure bladders and/or urinary incontinence despite conservative management, as well as sacral root neuromodulation with permanent stimulators for complex bladder dysfunction: vesical instability, sensory urgency, chronic pelvic pain and chronic voiding dysfunction. The literature is reviewed, both techniques are described and the results of the most significant series are discussed, with special reference to the first groups that utilized these techniques. There is ample experience in the application of sacral root electrical stimulation. The reported results are comparable with those achieved by other treatments, such as augmentation cystoplasty. Neurostimulation and neuromodulation techniques are simple, the complications are minimal and they do not prelude the use of other therapies.

    Currently, the 15 MW Heavy Water Research Reactor (HWRR) at China Institute of Atomic Energy (CIAE) in Beijing is the only neutron source available for neutron scattering experiments in China. A 60 MW tank-in-pool inverse neutron trap-type research reactor, China Advanced Research Reactor (CARR), now is being built at CIAE to meet the increasing demand of neutron scattering research in China. According to design, the maximum unperturbed thermal neutron flux would be expected to be 8x10 14 n/cm 2 .s in the reflector region. Seven out of nine tangential horizontal beam tubes will be dedicated for neutron scattering experiments. A cold source, a hot source and a 30x60 m 2 guide tube hall will also be constructed. In this paper, a brief introduction of HWRR, the existing neutron scattering facilities and research activities at HWRR, CARR, and the facilities to be built at CARR are presented. (author)

    2004-08-01

    Clinical trials of hyperthermia in combination with radiation therapy or chemotherapy undertaken over the past decades in Japan have been reviewed. Originally developed heating devices were mostly used for these trials, which include RF (radiofrequency) capacitive heating devices, a microwave heating device with a lens applicator, an RF intracavitary heating device, an RF current interstitial heating device, and ferromagnetic implant heating device. Non-randomized trials for various cancers, demonstrated higher response rate in thermoradiotherapy than in radiotherapy alone. Randomized trials undertaken for esophageal cancers also demonstrated improved local response with the combined use of hyperthermia. Furthermore, the complications associated with treatment were not generally serious. These clinical results indicate the benefit of combined treatment of hyperthermia and radiotherapy for various malignancies. On the other hand, the presently available heating devices are not satisfactory from the clinical viewpoints. With the advancement of heating and thermometry technologies, hyperthermia will be more widely and safely used in the treatment of cancers.

    Current activities of the Anthropogenic SO 2 /NO x Committee center around the compilation of Version 1 of the GEIA inventories. These inventories will be based on the GEIA-specified 1 degrees by 1 degrees grid (lower left corner at 180 degrees W/90 degrees S, west to east and south to north), reflect 1985 emissions and consist of two data sets: Version 1A inventories with annual emissions at one level and Version 1B inventories with seasonal emissions, two vertical levels (defined at 100 m) and sectoral split information. The basic information used for both versions of the GEIA inventories will be identical; i.e., emissions totals across both inventories will be the same. Work is being carried out in two complementary working groups; Carmen Benkovitz, Brookhaven National Laboratory, Upton, NY, USA heads the work on the annual inventory, Eva Voldner, Atmospheric Environment Services, Canada and Trevor Scholtz, ORTECH International, Canada, head the work on the seasonal inventory

    2014-03-01

    Full Text Available The current situation concerning research in ethnobotany and economic botany of Peruvian palms is analyzed through a review of the literature with emphasis on knowledge related to uses and vernacular names. Of the 136 Peruvian palm species, 104 have at least one use. A total of 268 different uses distributed in 16 categories were registered. The most frequent categories are "construction", "edible", "craft industry" and "medicinal". There are 109 palm species with at least one vernacular name in Peru. The consulted literature is analyzed in four categories: (i general studies in economic botany, (ii ethnographic and ethnobiological studies, (iii studies of South-American palms of economic interest, (iv studies that exclusively deal with the useful Peruvian palms. Ethnobotanical knowledge of Peruvian palms proves to be essentially descriptive, with much repetitive information. Studies that significantly contribute to the genetic or agronomical improvement of the economically promising palms are rare.

    International Nuclear Information System (INIS)

    Tsoskounoglou, Miltos; Ayerides, George; Tritopoulou, Efi

    2008-01-01

    This paper, analyses the factors impacting the price of crude oil in order to examine the likely evolution of the oil market and attempts to answer the question, whether cheap oil is already a thing of the past. Based on data made publicly available mostly by the major oil companies, it examines the effects of demand and supply, the evolution of world oil reserves, the trends in new discoveries of new oilfields, the evolution of world Gross Domestic Product (GDP), and the depletion of oil resources. The analysis concludes that the world peak in conventional oil production-the point beyond which oil production will irreversibly start declining-is approaching and will be reached, even according to the most optimistic scenarios, before 2040 and quite possibly much sooner. If the appropriate solutions for substituting crude oil and for conserving the use of energy are not implemented in time, then the current upward trend in oil prices is bound to continue

    Nowadays, nanotechnologies have shown wide application foreground in the biomedical field of medicine laboratory tests, drug delivery, gene therapy and bioremediation. However, in recent years, nanomaterials have been labeled poisonous, because of the disputes and misunderstandings of mainstream views on their safety. Besides, for the barriers of technical issues in preparation like: (1) low efficacy (poor PK & PD and low drug loading), (2) high cost (irreproducibility and difficulty in scale up), little of that research has been successfully translated into commercial products. Currently, along with the new theory of "physical damage is the origin of nanotoxicity", biodegradability and biocompatibility of nanomaterials are listed as the basic principle of safe application of nanomaterials. Combining scientific design based on molecular level with precision control of process engineering will provide a new strategy to overcome the core technical challenges. New turning point of translational medicine in nanotechnology may emerge.

    The rampant industrialization and unchecked growth of modern textile production facilities coupled with the lack of proper treatment facilities have proliferated the discharge of effluents enriched with toxic, baleful, and carcinogenic pollutants including dyes, heavy metals, volatile organic compounds, odorants, and other hazardous materials. Therefore, the development of cost-effective and efficient control measures against such pollution is imperative to safeguard ecosystems and natural resources. In this regard, recent advances in biotechnology and microbiology have propelled bioremediation as a prospective alternative to traditional treatment methods. This review was organized to address bioremediation as a practical option for the treatment of dyes by evaluating its performance and typical attributes. It further highlights the current hurdles and future prospects for the abatement of dyes via biotechnology-based remediation techniques. Copyright © 2018 Elsevier Ltd. All rights reserved.
