    1982-02-01

    The purpose of this paper is to present a brief description of fuel reprocessing and some present developments which show the reliability of nuclear energy as a long-term supply. The following topics are discussed: technical reasons for reprocessing; economic reasons for reprocessing; past experience; justification for advanced reprocessing R and D; technical aspects of current reprocessing development. The present developments are mainly directed at the reprocessing of breeder reactor fuels but there are also many applications to light-water reactor fuel reprocessing. These new developments involve totally remote operation, and maintenance. To demonstrate this advanced reprocessing concept, pilot-scale demonstration facilities are planned with commercial application occurring sometime after the year 2000

  3. In situ leaching of uranium: Technical, environmental and economic aspects

    International Nuclear Information System (INIS)

    1989-01-01

    Within the framework of its activities in nuclear raw materials the International Atomic Energy Agency has convened a series of meetings to discuss various aspects of uranium ore processing technology, recovery of uranium from non-conventional resources and development of projects for the production of uranium concentrates including economic aspects. As part of this continuing effort to discuss and document important aspects of uranium production the IAEA convened a Technical Committee Meeting on Technical, Economic and Environmental Aspects of In-Situ Leaching. Although the use of this technique is limited by geological and economic constraints, it has a significant potential to produce uranium at competitive prices. This is especially important in the current uranium market which is mainly characterised by large inventories, excess production capability and low prices. This situation is not expected to last indefinitely but it is unlikely to change drastically in the next ten years or so. This Technical Committee Meeting was held in Vienna from 3 to 6 November 1987 with the attendance of 24 participants from 12 countries. Eight papers were presented. Technical sessions covered in-situ mining research, environmental and licensing aspects and restoration of leached orebodies; the technological status of in-situ leaching, the current status and future prospects of in-situ leaching of uranium in Member States, general aspects of planning and implementation of in-situ projects and the economics of in-situ leaching.

    2017-01-01

    Extracorporeal photochemotherapy (ECP) is considered as an immune modulating therapy majorly targeting the T cells of the Immune system. ECP induces an anti-inflammatory condition with tolerogenic responses without inducing a global immunosuppression state which is a typical feature of other therapeutic options such as steroids. Clinical indication of ECP has grown over time since its initial applications. Our review discusses the technical aspects of the concept of photopheresis with the available methods for its clinical applications.

  9. VIRTUAL PHILOSOPHER PROJECT: PHILOSOPHICAL, PEDAGOGICAL AND TECHNICAL ASPECTS

    Directory of Open Access Journals (Sweden)

    E. V. Kuchinov

    2017-01-01

    Full Text Available The article describes philosophical and pedagogical aspects of an idea of the ‘virtual philosopher’ project developed at creative sessions at Minin University and technically concretized during interaction with the Laboratory of Mobile Services. ‘Virtual philosopher’ is thought to deliver creative automation of routine operations; producing contingent matter for philosophical processing as well as elements of the philosophical artificial intelligence and forms of ‘artificial life’. Project implementation may lead to the creation of an unparalleled educational technology that functions on the principles of flexibility, nonlinearity, affective inclusion and gamification of the educational process. Based on specific character of problems raised, rhizomatic analysis of the philosophical communities’ requests, assessment of their technical feasibility and technical development, provisions are made on the feasibility, prospects and productivity of this project.

    In force since 2001, the Federal Law 10.308 states, in article 37, that the Comissao Nacional de Energia Nuclear - CNEN should start studies for the implementation of a final radioactive waste repository, 'in the shortest timeframe technically feasible'. Nevertheless, not only technical aspects have to be taken into account to accomplish with this schedule, but, also factors of political, economic and social nature. In this paper, the importance and impact of public acceptance aspects are discussed, as well as the methodology of site selection for radioactive wastes repositories, and proposals to accommodate the emanated criteria from the existing legislation. Additionally, practical results from the international experience in the implementation of such deposits are presented. (author)

    2002-01-01

    What was first viewed by scientists and engineers simply as a common technical problem has now become a major social issue. The choice of a long-term solution for waste from the nuclear industry takes into consideration all aspects of the controversy, now an integral part of R and D projects. Research, development, and innovation must provide a 'constructive' way out of this type of controversy. This is the conviction that scientists and sociologists have come to after two years of cooperation. (authors)

  12. Technical aspects of ageing for long-term operation

    International Nuclear Information System (INIS)

    2003-01-01

    The aspects of plant ageing management gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. This document restricts itself to the technical aspects of the basis for long-term operation. Its objective is the characterisation of technical key items. Regulatory aspects are being discussed within CNRA. The light water reactor (LWR) nuclear power plants in operation are generically of pressurised water reactor (PWR) or boiling water reactor (BWR) type. The design principles of the nuclear steam supply system (NSSS) are proven in long-term operation as well as the principles being applied to the balance of plant (BOP), although a rather large variety of technical solutions do exist. The steps in the developments were tremendous in the 60's and 70's up to a power output of 1200 MWe followed by a period of further optimisation in the 80's and 90's, which raised it close to 1500 MWe. The NPPs in operation can be grouped into different generations of design in order to characterise similarities in technical principles and manufacturing standards. In the area of civil and mechanical structures and components there has been continuous development to optimise the design, the materials used as well as the manufacturing technology. The majority of these structures and components is still in use. In principle there are no major obstacles to further use of these

    Endobronchial ultrasound (EBUS) was introduced in the last decade, enabling real-time guidance of transbronchial needle aspiration (TBNA) of mediastinal and hilar structures and parabronchial lung masses. The many publications produced about EBUS-TBNA have led to a better understanding of the performance characteristics of this procedure. The goal of this document was to examine the current literature on the technical aspects of EBUS-TBNA as they relate to patient, technology, and proceduralist factors to provide evidence-based and expert guidance to clinicians. Rigorous methodology has been applied to provide a trustworthy evidence-based guideline and expert panel report. A group of approved panelists developed key clinical questions by using the PICO (population, intervention, comparator, and outcome) format that addressed specific topics on the technical aspects of EBUS-TBNA. MEDLINE (via PubMed) and the Cochrane Library were systematically searched for relevant literature, which was supplemented by manual searches. References were screened for inclusion, and well-recognized document evaluation tools were used to assess the quality of included studies, to extract meaningful data, and to grade the level of evidence to support each recommendation or suggestion. Our systematic review and critical analysis of the literature on 15 PICO questions related to the technical aspects of EBUS-TBNA resulted in 12 statements: 7 evidence-based graded recommendations and 5 ungraded consensus-based statements. Three questions did not have sufficient evidence to generate a statement. Evidence on the technical aspects of EBUS-TBNA varies in strength but is satisfactory in certain areas to guide clinicians on the best conditions to perform EBUS-guided tissue sampling. Additional research is needed to enhance our knowledge regarding the optimal performance of this effective procedure. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc.

    Chicken, J.C.

    1988-01-01

    This report describes the results of the study that was made, under Contract No ECI-1390-B7221-85D, for the European Atomic Energy Community. The aim of the study was to examine and assess the feasibility of developing coherent and uniform criteria for judging the acceptability of the technical aspects of the risks associated with potentially hazardous installations. The report is arranged in five main parts. First the nature of hazardous installations is considered and this provides the basis for examination of the currently-used technical risk acceptability criteria. Next, the possible forms of criteria are explored and then universally consistent partial and overall technical risk acceptability criteria are proposed. Following this the implications of using the criteria proposed at the design, regulatory and operating levels are examined. Then, by testing the criteria against some real decisions, the practical problems of using the proposed criteria are explored. This leads to consideration of possible alternatives to the proposed criteria. Finally the conclusions that appear to be justified are summarized and the need for further work is identified

  19. Technical, economic and institutional aspects of regional spent fuel storage facilities

    International Nuclear Information System (INIS)

    2005-11-01

    A particular challenge facing countries with small nuclear programmes is the preparation for extended interim storage and then disposal of their spent nuclear fuel. The costs and complications of providing for away-from-reactor storage facilities and/or geological repositories for relatively small amounts of spent fuel may be prohibitively high, motivating interest in regional solutions. This publication addresses the technical, economic and institutional aspects of regional spent fuel storage facilities (RSFSF) and is based on the results of a series of meetings on this topic with participants from IAEA Member States. Topics discussed include safety criteria and standards, safeguards and physical protection, fuel acceptance criteria, long term stability of systems and stored fuel, selection of site, infrastructure aspects, storage technology, licensing, operations, transport, decommissioning, as well as research and development. Furthermore the publication comprises economic, financial and institutional considerations including organizations and legal aspects followed by political and public acceptance and ethical considerations. Approaches and processes for implementation are discussed, as well as the overall benefits and risks of implementing a regional facility. It is illustrated that implementing a RSFSF facility would involve simultaneously addressing a wide range of diverse challenges. The appendix to this report tabulates the numerous issues that have been touched upon in the study. It appears, however, from the discussions that the challenges can in principle be met; the RSFSF concept is technically feasible and potentially economically viable. The technical committees producing this report did not identify any obvious institutional deficiencies that would prevent completion of such a project. Storing spent fuel in a few safe, reliable, secure facilities could enhance safeguards, physical protection and non-proliferation benefits. The committee also

    Identification of threats to organisations and risk assessment often take into consideration the pure technical aspects, overlooking the vulnerabilities originating from attacks on a social level, for example social engineering, and abstracting away the physical infrastructure. However, attacks...... would close this gap, however, it would also result in complicating the formal treatment and automatic identification of attacks. This dissertation shows that applying a system modelling approach to sociotechnical systems can be used for identifying attacks on organisations, which exploit various levels...... process calculus, we develop a formal analytical approach that generates attack trees from the model. The overall goal of the framework is to predict, prioritise and minimise the vulnerabilities in organisations by prohibiting the overall attack or at least increasing the difficulty and cost of fulfilling...

    2017-12-01

    Pancreatic cancer is the fourth leading cause of cancer-related death in the Unites States and is rising in incidence. For the 15-25% of patients who do not have either metastatic or locally advanced disease, surgical resection with pancreaticoduodenectomy is the standard of care and results in improved 5-year survival of 15-25%. While mortality at high-volume centers is less than 5%, morbidity remains high at approximately 30-45%. This paper reviews technical aspects of pancreaticoduodenectomy and their outcomes. Specifically, we review technique and the outcome literature on vascular reconstruction, attempts to decrease delayed gastric emptying (DGE), including pylorus-preserving versus classic pancreaticoduodenectomy and gastrojejunostomy (GJ) technique, as well as attempts to decrease the rate of pancreatic fistula, including the use of pancreatic stents, fibrin sealant, and pancreaticojejunostomy (PJ) technique. Vascular resection and reconstruction have been associated with increased morbidity and mortality. However, the literature suggests that if it allows for an R0 resection, the survival is improved with comparable complication rates. DGE, one of the most common post-pancreaticoduodenectomy complications, has not been reliably decreased with various technical modifications of the GJ. The incidence of pancreatic fistula, one of the most morbid postoperative complications, is not definitively reduced by either the use of pancreatic stents or fibrin sealant. Additional research is needed to determine methods to further decrease rates of morbidity.

    Laparoscopic resection of transverse colon cancer at splenic flexure is technical demanding and its efficacy remains controversial. The aim of this study was to investigate its technical aspects such as pitfalls and overcoming them, and to demonstrate the short-term and oncologic long-term outcomes. To overcome the difficulty in laparoscopic resection of transverse colon cancer at splenic flexure, we recognized the following technical tips as essential. First of all, we have to precisely identify major vessels variations feeding tumor. Secondary, anatomical dissection of mesocolon through medial approach is indispensible. Third, safe takedown of splenic flexure to fully mobilization of left hemicolon is mandatory. This cohort study analyzed 95 patients with stage II (43) and III (52) underwent resection of transverse colon cancer at splenic flexure. 61 laparoscopic surgeries (LAC) and 34 conventional open surgeries (OC) from December 1996 to December 2009 were evaluated. Short-term and oncologic long-term outcomes were recorded. Operative time was longer in LAC. However, blood loss was less, recovery of bowel function and hospital stay were shorter in LAC. There was no conversion in LAC and no significant difference in the postoperative complications. Regarding oncologic long-term outcomes, there were no significant differences between OC and LAC. Laparoscopic resection of transverse colon cancer at splenic flexure resulted in acceptable short-term and oncologic long-term outcomes. Once technical tips acquired, laparoscopic resection of transverse colon cancer at splenic flexure could be feasible as minimally invasive surgery.

  11. Aspects of the role of scientific-technical expert knowledge in administrative court procedures on licensing of large technical projects

    International Nuclear Information System (INIS)

    Wagner, H.

    1983-01-01

    On the basis of atomic energy law, the author explains some specific problems associated with the respective roles of experts (or expert bodies) and courts of law. In legal theory, it is comparatively easy to draw the line between the two functions, but in practice this delimination meets with difficulties. Finally, the author proposes to improve the definitions of the respective functions of experts (expert bodies) and courts of law in procedures dealing with permits of large technical facilities as follows: A highly qualified, independent body of experts in a technically representative composition lays down, in a binding way, the main elements of the safety standard of a specific plant or type of plant. The responsible administrative authority, after having examined all other legal conditions, grants the permit for that plant. There are no objections to such a model in the light either of aspects of constitutional law or of legal policy or constitutional policy, not are there any practical reasons against this approach. The only doubtful aspect is the present political feasibility. (orig.) [de

  12. Using plant status data for off-site emergency management: Technical and political aspects

    International Nuclear Information System (INIS)

    Govaerts, P.

    2004-01-01

    Subsequent to the TMI and Chernobyl accidents, emergency management is investigating the possibility of taking balanced decisions on interventions as early as possible. This process relies more and more on in-plant data to assess the term of releases. The paper discusses the regulatory aspects of the communication related to the source term between the utility and the national authorities, and the authorities of a host country and neighbouring countries that may be affected. The technical aspects of the assessment process are summarised, with the emphasis on the handling of uncertainties. Notwithstanding the technical progress, the main dilemma for the decision makers remains the same. Risk management and prevention measures become more familiar to authorities. Utilities and national authorities have to get rid of complexes with respect to accidents covered by the accepted residual risk. International emergency management has to look for an organisation type ensuring the continuity of countermeasures independent of the presence of administrative borders, and with respect to national autonomies.

    Lauppe, W.D.; Stein, G.; Rezniczek, A.; Stienen, U.

    1983-12-01

    The electronic remote monitoring systems RECOVER and LOVER were developed to comply with the IAEA's tasks concerning international nuclear materials safeguards with the aim of reducing the inspection expenditure and enhancing control effectiveness. The present study on the technical, economic and legal aspects of an application of these systems is intended to show possible implications and provide argumentation aids for discussions on the application of these systems. RECOVER and LOVER offer the possibility of establishing a direct communication path between containment and surveillance system (c/s), instruments at the site of application and a central monitoring station. The demonstration versions of both systems have shown that remote interrogation of data under safeguards-specific boundary conditions (e.g. requirement of tamper safety) will be technically feasible.

Today, there are five different LDL-apheresis systems available: cascade filtration or lipid filtration, immunoadsorption, heparin-induced LDL precipitation, dextran sulfate LDL adsorption, and the LDL hemoperfusion. There is a strong correlation between hyperlipidemia and atherosclerosis. Besides the elimination of other risk factors, in severe hyperlipidemia therapeutic strategies should focus on a drastic reduction of serum lipoproteins. Despite maximum conventional therapy with a combination of different kinds of lipid-lowering drugs, sometimes the goal of therapy cannot be reached. Hence, in such patients, treatment with LDL-apheresis is indicated. Technical and clinical aspects of these five different LDL-apheresis methods are shown here. There were no significant differences with respect to or concerning all cholesterols, or triglycerides observed. With respect to elevated lipoprotein (a levels, however, the immunoadsorption method seems to be most effective. The different published data clearly demonstrate that treatment with LDL-apheresis in patients suffering from severe hyperlipidemia refractory to maximum conservative therapy is effective and safe in long-term application.

    BATAN is planning to establish an accelerator-based laboratory at P3TM Yogyakarta as an effort in the development and use of accelerator technology for improving industrial performance and public welfare. This paper reviews several aspects of cyclotron technology and describes the combination of a linear accelerator - cyclotron system as an alternative to be considered in the planing of the laboratory. The progress of cyclotron technology is discussed covering three generations, i.e. conventional cyclotron, synchrocyclotron and AVF cyclotron generations. The planning should not consider the accelerator application for radioisotope production because it is established in Serpong with the existing negative ion cyclotron. The proposed facility at P3TM may comprise two linear accelerators coupled with a positive ion cyclotron of synchrocyclotron generation. In fact, the attachment of the synchrocyclotron unit is flexible and it can be installed subsequently if the higher energy particle beam, which can not be produced by the linear accelerators, is extremely needed. Some technical aspects related to ion beam application, building construction and infrastructure, human resources, and specification of function test are discussed for additional information in the implementation of the planning.

    The orange juice industry produces, at the end of the residue extraction, a by-product called orange press liquor. Considering its high content of soluble solids and the large volume of the liquor produced in Brazilian orange juice plants, an earlier study was conducted on the technical viability of using orange press liquor as raw material for a new distilled beverage, with promising results. With a view to increasing efficiency and possibly attracting investments in the growing international market for new and exotic beverages, the aim of the present study was to optimize the orange press liquor spirit process and to evaluate the economic aspects of its production. The results showed that this process can yield a good quality beverage, comparable to the sugar cane spirit cachaça and other similar products, as well as having economic advantages and potential for immediate further growth, without extra investment costs.

    Single cells are basic physiological and biological units that can function individually as well as in groups in tissues and organs. It is central to identify, characterize and profile single cells at molecular level to be able to distinguish different kinds, to understand their functions and determine how they interact with each other. During the last decade several technologies for single-cell profiling have been developed and used in various applications, revealing many novel findings. Quantitative PCR (qPCR) is one of the most developed methods for single-cell profiling that can be used to interrogate several analytes, including DNA, RNA and protein. Single-cell qPCR has the potential to become routine methodology but the technique is still challenging, as it involves several experimental steps and few molecules are handled. Here, we discuss technical aspects and provide recommendation for single-cell qPCR analysis. The workflow includes experimental design, sample preparation, single-cell collection, direct lysis, reverse transcription, preamplification, qPCR and data analysis. Detailed reporting and sharing of experimental details and data will promote further development and make validation studies possible. Efforts aiming to standardize single-cell qPCR open up means to move single-cell analysis from specialized research settings to standard research laboratories. Copyright © 2017 Elsevier Ltd.

  7. Maturity index on reliability: covering non-technical aspects of IEC61508 reliability certification

    Brombacher, A.C.

    1999-01-01

    One of the more recent developments in the field of reliability and safety is the realisation that these aspects are not only a function of the product itself, but also of the organisation realising this product. A second development is a trend from an often predominantly qualitative analysis towards a quantitative analysis. In contrast to the (older) DIN 0801, the (more recent) IEC61508 requires, on product level, also a quantitative analysis and, on organisational level, an assessment of the lifecycle of a product by analysing the (maturity of the) relevant business processes (DIN V VDE 0801. Grundsaetze fuer Rechner in Systemen mit Sicherheitsaufgaben, 1990; DIN V 0801. Grundlegende Sicherheitsbetrachtungen fuer MSR-Schutzeinrichtungen, 1994; DIN V VDE 0801 A1. Grundsaetze fuer Rechner in Systemen mit Sicherheitsaufgaben, Aenderung A1, 1994; IEC 61508 Functional Safety of electrical/electronic/programmable electronic safety-related systems, draft 4.0, 1997). The IEC standard 61508 covers: (i) technical aspects, both on a quantitative and a qualitative level; (ii) organisational aspects, both on aspects of maturity of business processes (quantitative) and on aspects of the definition and application of procedures (qualitative). This paper shows the necessity for an analysis on all aspects in a safety certification process, and presents an overview of the available tools and techniques for the various quadrants. As methods and tools for especially quadrant C are currently unavailable, this paper will propose a method to assess and improve the maturity of an organisation on reliability management: the maturity index on reliability (MIR)

    The usage of functional data in radiation therapy (RT) treatment planning (RTP) process is currently the focus of significant technical, scientific, and clinical development. Positron emission tomography (PET) using ((18)F) fluorodeoxyglucose is being increasingly used in RT planning in recent years. Fluorodeoxyglucose is the most commonly used radiotracer for diagnosis, staging, recurrent disease detection, and monitoring of tumor response to therapy (Lung Cancer 2012;76:344-349; Lung Cancer 2009;64:301-307; J Nucl Med 2008;49:532-540; J Nucl Med 2007;48:58S-67S). All the efforts to improve both PET and computed tomography (CT) image quality and, consequently, lesion detectability have a common objective to increase the accuracy in functional imaging and thus of coregistration into RT planning systems. In radiotherapy, improvement in target localization permits reduction of tumor margins, consequently reducing volume of normal tissue irradiated. Furthermore, smaller treated target volumes create the possibility of dose escalation, leading to increased chances of tumor cure and control. This article focuses on the technical aspects of PET/CT image acquisition, fusion, usage, and impact on the physics of RTP. The authors review the basic elements of RTP, modern radiation delivery, and the technical parameters of coregistration of PET/CT into RT computerized planning systems. Copyright © 2012 Elsevier Inc.

    The only indication for coronary revascularization is elimination of ischaemia. Invasive hemodynamic methods (fractional flow reserve - FFR and instantaneous wave-free ratio (iFR) are superior to coronary angiography in detection of lesions causing myocardial ischaemia. Current European guidelines for myocardial revascularization recommend using of FFR for detection of functional assessment of lesions severity in category IA and number of these procedures increases. However, routine usage of these methods requires knowledge of technical requirements and limitations. The aim of the study is to summarise good clinical practice for FFR and iFR measurements with explanation of possible technical challenges, that are necessary for increasing of measurement accuracy. Authors describe frequent technical mistakes and malpractice during invasive assessment of lesion severity in coronary arteries.

    Morbid obesity is a significant clinical problem in the western world. Various surgical restrictive procedures have been described as an aid to weight reduction when conservative treatments fail. Adjustable laparoscopic gastric banding (LAPBAND) has been popularized as an effective, safe, minimally invasive, yet reversible technique for the treatment of morbid obesity. Radiological input is necessary in the follow-up of these patients and the diagnosis of complications peculiar to this type of surgery. In this review we will highlight the technical aspects of radiological follow-up and the lessons learnt over the last 5 years.

    Tablet subdivision is a common practice used mainly for dose adjustment. The aim of this study was to investigate how the technical aspects of production as well as the method of tablets subdivision (employing a tablet splitter or a kitchen knife) influence the accuracy of this practice. Five drugs commonly used as subdivided tablets were selected. For each drug, the innovator drug product, a scored-generic and a non-scored generic were investigated totalizing fifteen drug products. Mechanical and physical tests, including image analysis, were performed. Additionally, comparisons were made between tablet subdivision method, score, shape, diluent composition and coating. Image analysis based on surface area was a useful tool as an alternative assay to evaluate the accuracy of tablet subdivision. The tablet splitter demonstrates an advantage relative to a knife as it showed better results in weight loss and friability tests. Oblong, coated and scored tablets had better results after subdivision than round, uncoated and non-scored tablets. The presence of elastic diluents such as starch and dibasic phosphate dehydrate conferred a more appropriate behaviour for the subdivision process than plastic materials such as microcrystalline cellulose and lactose. Finally, differences were observed between generics and their innovator products in all selected drugs with regard the quality control assays in divided tablet, which highlights the necessity of health regulations to consider subdivision performance at least in marketing authorization of generic products.

    1982-12-01

    This report discusses those technical aspects of the operation of the Medium Energy Accelerator at NIKHEF-K which affect the environment. The accelerator produces an electron beam with a maximum capacity of 300 kW and, as by-products, intense gamma and neutron radiations. These radiations can contaminate components of the accelerator and the direct surroundings. The electron beam can also generate ozone in the air. The accelerator produces a small quantity of radioactive waste itself and research in the chemistry department also leads to the production of radioactive waste. These wastes are stored temporarily and transported for treatment/storage elsewhere in Holland once a year. (Auth.)

    2004-01-01

    E-health is an emerging field on the intersection of medical information technologies, public health and business, referring to health services and information delivered or enhanced through the Internet and related technologies. Portal technology, allowing services to be accessible over the Internet is a perfect tool for providing e-health services. The use of portal technologies has had deep influence on the architecture of the whole e-health system, both regarding new subsystems and older ones which we want to integrate with the portal. Portals provide new possibilities for creating novel types of e-health applications as well. In this paper we provide a brief overview of e-health systems and portal technologies, and present many technical aspects of portal technology application for e-health systems such as the architecture of portal-based e-health systems, graphical user interfaces, access to various e-health systems' resources, personalization, security and privacy.

    1989-01-01

    Before screening programmes using mammography are implemented, a cost benefit analysis has to be made and quality-control programme for the technical and dosimetric aspects adopted, including daily checks on film processing and total mammography procedure (radiography of a reference phantom, for which the average density, limiting value ± 0.20%, and focal charge is determined and which allows assessment of physical image quality) The installation of a MAs meter is essential for daily checks and can be used for determination of absorbed dose. Accurate determination of tube voltage (limiting value ±0.5 kV) is essential in regard to absorbed dose variations. Focal spot size should be measured rather than relying on the value specified by the manufacturer. The determination of the focal charge (mAs) value for actual radiographs of female breasts combined with a measurement of compressed breast thickness provides information on absorbed dose values for actual radiographs. An approximately 50 mm thick poly(methyl methacrylate) phantom can be used for determination of absorbed dose in mammography. (author)

    Purpose. This study was designed to evaluate the clinical efficacy of CT-guided bipolar and multipolar radiofrequency ablation (RF ablation) of renal cell carcinoma (RCC) and to analyze specific technical aspects between both technologies. Methods. We included 22 consecutive patients (3 women; age 74.2 {+-} 8.6 years) after 28 CT-guided bipolar or multipolar RF ablations of 28 RCCs (diameter 2.5 {+-} 0.8 cm). Procedures were performed with a commercially available RF system (Celon AG Olympus, Berlin, Germany). Technical aspects of RF ablation procedures (ablation mode [bipolar or multipolar], number of applicators and ablation cycles, overall ablation time and deployed energy, and technical success rate) were analyzed. Clinical results (local recurrence-free survival and local tumor control rate, renal function [glomerular filtration rate (GFR)]) and complication rates were evaluated. Results. Bipolar RF ablation was performed in 12 procedures and multipolar RF ablation in 16 procedures (2 applicators in 14 procedures and 3 applicators in 2 procedures). One ablation cycle was performed in 15 procedures and two ablation cycles in 13 procedures. Overall ablation time and deployed energy were 35.0 {+-} 13.6 min and 43.7 {+-} 17.9 kJ. Technical success rate was 100 %. Major and minor complication rates were 4 and 14 %. At an imaging follow-up of 15.2 {+-} 8.8 months, local recurrence-free survival was 14.4 {+-} 8.8 months and local tumor control rate was 93 %. GFR did not deteriorate after RF ablation (50.8 {+-} 16.6 ml/min/1.73 m{sup 2} before RF ablation vs. 47.2 {+-} 11.9 ml/min/1.73 m{sup 2} after RF ablation; not significant). Conclusions. CT-guided bipolar and multipolar RF ablation of RCC has a high rate of clinical success and low complication rates. At short-term follow-up, clinical efficacy is high without deterioration of the renal function.

    2001-01-01

    A successful liberalisation of energy markets is taking place in the Baltic countries (Estonia, Latvia, Lithuania), that is why it is important to investigate the methodological and technical aspects as well as the effect of this process upon the development of energy supply in the North European region. Energy supply to the Baltic countries is characterised by the fact that energy resources there are mainly supplied from the CIS, where there is a rather difficult prognostic energy market with sharp price fluctuations (sometimes supplies are completely cut). At the same time, by using the CIS energy resources, the development of the energy sector may significantly influence the total North European energy supplies. Energy saving measures and energy-efficient technologies in the following years will greatly influence energy market and energy consumption. This is an actual problem for such countries as Latvia, where the main part of its energy carriers is imported from neighbouring countries.(author)

    The objective of this study was to evaluate the technical aspects and clinical efficacy of selective embolization for post-endoscopic sphincterotomy bleeding. We reviewed the records of 10 patients (3%; M:F 6:4; mean age, 63.3 years) that underwent selective embolization for post-endoscopic sphincterotomy bleeding among 344 patients who received arteriography for nonvariceal upper gastrointestinal bleeding from 2000 to 2009. We analyzed the endoscopic procedure, onset of bleeding, underlying clinical condition, angiographic findings, interventional procedure, and outcomes in these patients. Among the 12 bleeding branches, primary success of hemostasis was achieved in 10 bleeding branches (83%). Secondary success occurred in two additional bleeding branches (100%) after repeated embolization. In 10 patients, post-endoscopic sphincterotomy bleedings were detected during the endoscopic procedure (n = 2, 20%) or later (n = 8, 80%), and the delay was from one to eight days (mean, 2.9 days; {+-} 2.3). Coagulopathy was observed in three patients. Eight patients had a single bleeding branch, whereas two patients had two branches. On the selective arteriography, bleeding branches originated from the posterior pancreaticoduodenal artery (n = 8, 67%) and anterior pancreaticoduodenal artery (n = 4, 33%), respectively. Superselection was achieved in four branches and the embolization was performed with n-butyl cyanoacrylate. The eight branches were embolized by combined use of coil, n-butyl cyanoacrylate, or Gelfoam. After the last embolization, there was no rebleeding or complication related to embolization. Selective embolization is technically feasible and an effective procedure for post-endoscopic sphincterotomy bleeding. In addition, the posterior pancreaticoduodenal artery is the main origin of the causative vessels of post-endoscopic sphincterotomy bleeding.

    Purpose. This study was designed to evaluate the clinical efficacy of CT-guided bipolar and multipolar radiofrequency ablation (RF ablation) of renal cell carcinoma (RCC) and to analyze specific technical aspects between both technologies. Methods. We included 22 consecutive patients (3 women; age 74.2 ± 8.6 years) after 28 CT-guided bipolar or multipolar RF ablations of 28 RCCs (diameter 2.5 ± 0.8 cm). Procedures were performed with a commercially available RF system (Celon AG Olympus, Berlin, Germany). Technical aspects of RF ablation procedures (ablation mode [bipolar or multipolar], number of applicators and ablation cycles, overall ablation time and deployed energy, and technical success rate) were analyzed. Clinical results (local recurrence-free survival and local tumor control rate, renal function [glomerular filtration rate (GFR)]) and complication rates were evaluated. Results. Bipolar RF ablation was performed in 12 procedures and multipolar RF ablation in 16 procedures (2 applicators in 14 procedures and 3 applicators in 2 procedures). One ablation cycle was performed in 15 procedures and two ablation cycles in 13 procedures. Overall ablation time and deployed energy were 35.0 ± 13.6 min and 43.7 ± 17.9 kJ. Technical success rate was 100 %. Major and minor complication rates were 4 and 14 %. At an imaging follow-up of 15.2 ± 8.8 months, local recurrence-free survival was 14.4 ± 8.8 months and local tumor control rate was 93 %. GFR did not deteriorate after RF ablation (50.8 ± 16.6 ml/min/1.73 m 2 before RF ablation vs. 47.2 ± 11.9 ml/min/1.73 m 2 after RF ablation; not significant). Conclusions. CT-guided bipolar and multipolar RF ablation of RCC has a high rate of clinical success and low complication rates. At short-term follow-up, clinical efficacy is high without deterioration of the renal function.

    In August 2004, the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) ceased operation due to a failure of the 5V mechanism power converter in the Side 2 Low Voltage Power Supply (LVPS2). The failure precluded movement of any STIS mechanism and, because of the earlier (2001) loss of the Side 1 electronics chain, left the instrument shuttered and in safe mode after 7.5 years of science operations. A team was assembled to analyze the fault and to determine if STIS repair (STIS-R) was feasible. The team conclusively pinpointed the Side 2 failure to the 5V mechanism converter, and began studying EVA techniques for opening STIS during Servicing Mission 4 (SM4) to replace the failed LVPS2 board. The restoration of STIS functionality via surgical repair by astronauts has by now reached a mature and final design state, and will, along with a similar repair procedure for the Advanced Camera for Surveys (ACS), represent a first for Hubble servicing. STIS-R will restore full scientific functionality of the spectrograph on Side 2, while Side 1 will remain inoperative. Because of the high degree of complementarity between STIS and the new Cosmic Origins Spectrograph (COS, to be installed during SM4)), successful repair of the older spectrograph is an important scientific objective. In this presentation, we focus on the technical aspects associated with STIS-R.

    A first report is a contribution to the elaboration of a plan aiming at the substitution of fossil energies, at the development of heat deliveries, while maintaining network economic profitability. Such a plan is based on the connection of buildings, the renovation, extension and interconnection of existing networks, and the creation of new heat networks. The study addressed technical, urban, financial, judicial and cartographic aspects. Public statistical data have been used and interviews of actors (network funders, representatives of delegating authorities, social landlords, administrations, and technical professions) have been performed. A guide of good practices is proposed regarding contract reviewing conditions, possibilities of revision of subscribed power. Prospective issues are discussed: strategic stakes and deposits, actions paths and tools, strategy and action plan. Appendices address methodologies, organisation of the geographical information system, judicial aspect with the circular of 1982, financial data and aspects. Then, a set of reports more precisely presents various aspects addressed as a contribution for the study of heat networks in Ile-de-France: the judicial aspect (present status, guide of good judicial practices), the economic aspect (present status of sale prices and costs, analysis of financing, of revision formula), and an assessment of urban heating development (context, technical aspect, analysis of the geographical information system)

    Users of ecstasy (3,4-methylenedioxymethamphetamine; MDMA) may be at risk of developing MDMA-induced injury to the serotonin (5-HT) system. Previously, there were no methods available for directly evaluating the neurotoxic effects of MDMA in the living human brain. However, development of in vivoneuroimaging tools have begun to provide insights into the effects of ecstasy on the human brain. Single photon emission computed tomography (SPECT), positron emission computed tomography (PET) and proton magnetic resonance spectroscopy (1H-MRS) studies which have evaluated ecstasy's neurotoxic potential will be reviewed and discussed in terms of technical aspects, conceptual issues and future prospects. Although PET and SPECT may be limited by several factors such as the low cortical uptake and the use of a non-optimal reference region (cerebellum) the few studies conducted so far provide suggestive evidence that people who heavily use ecstasy are at risk of developing subcortical, and probably also cortical reductions in serotonin transporter (SERT) densities, a marker of 5-HT neurotoxicity. There seem to be dose-dependent and transient reductions in SERT for which females may be more vulnerable than males. 1H-MRS appears to be a less sensitive technique for studying ecstasy's neurotoxic potential. Whether individuals with a relatively low ecstasy exposure also demonstrate loss of SERT needs to be determined. Because most studies have had a retrospective design, in which evidence is indirect and differs in the degree to which any causal links can be implied, longitudinal studies in human ecstasy users are needed to draw definite conclusions.

    This study aimed to analyze the technical and tactical aspects of the Italian under-18 Academy Rugby Union in relation to different academies, regional tournaments, and game outcomes. A notational analysis (forty-four indicators) was performed on 16 games (2014-15 season) to evaluate strong differences (P ≤ 0.05; moderate-large effect sizes) according to variables. Among academies, strong differences were showed for defensive breakdown where the defending support is much (range=77-87%), equal (range=11-32%), and less (range=2-12%) numerous than the attacking support, total tackles (range=64-122) and passes (range=72-151), pass to possession ratio (range=6-10), possession lost due to an error (range=28-59%), and ball in play in own (range=8-25%) and opponent (range=7-31%) 22m area indicators. For tournaments, effects emerged for offensive breakdown when the ball is used quickly employing maximum 2 attacking supports (range=20-30%) and is not used quickly (range=28-41%), total penalty kicks (range=11-16), and sequences period 0-10 (range=26-35%) and 10-40 s (range=47-55%). Conversely, winning and losing academies reported differences with small effect sizes. These results highlight that the technical and tactical aspects of the Italian under-18 Academy Rugby Union are quite homogeneous, suggesting that FIR coaching staffs are more oriented to players' skills than successful games. However, tactical, and strength and conditioning coaches can benefit from the findings of this study, focusing training on cognitive, strength, and repeated sprint abilities with and without change of direction for improving the occurrence of "set pieces won/regained" and "ball in play in opponent 22m area", which appear as the key of the game in this rugby competition level.

    To review the emerging role of technical and non-technical simulation in urological education and training. A review was conducted to examine the current role of simulation in urology training. A PUBMED search of the terms 'urology training', 'urology simulation' and 'urology education' revealed 11,504 titles. Three hundred and fifty-seven abstracts were identified as English language, peer reviewed papers pertaining to the role of simulation in urology and related topics. Key papers were used to explore themes. Some cross-referenced papers were also included. There is an ongoing need to ensure that training time is efficiently utilised while ensuring that optimal technical and non-technical skills are achieved. Changing working conditions and the need to minimise patient harm by inadvertent errors must be taken into account. Simulation models for specific technical aspects have been the mainstay of graduated step-wise low and high fidelity training. Whole scenario environments as well as non-technical aspects can be slowly incorporated into the curriculum. Doing so should also help define what have been challenging competencies to teach and evaluate. Dedicated time, resources and trainer up-skilling are important. Concurrent studies are needed to help evaluate the effectiveness of introducing step-wise simulation for technical and non-technical competencies. Simulation based learning remains the best avenue of progressing surgical education. Technical and non-technical simulation could be used in the selection process. There are good economic, logistic and safety reasons to pursue the process of ongoing development of simulation co-curricula. While the role of simulation is assured, its progress will depend on a structured program that takes advantage of what can be delivered via this medium. Overall, simulation can be developed further for urological training programs to encompass technical and non-technical skill development at all stages, including

  8. Indications and technical aspects of brachytherapy in breast conserving treatment of breast cancer

    International Nuclear Information System (INIS)

    Erik Van, Limbergen

    2003-01-01

    Improved local control rates have been demonstrated in retrospective studies as well as in randomized trials on brachytherapy with increasing doses to the tumour bed. The higher local control obtained by interstitial breast implants, as compared to external photon or electron beam boosts, have been mainly attributed to the higher doses actually delivered to the tumour bed by these implants for the same nominal dose as compared to external beam radiotherapy (RT). On the other hand, poor cosmesis has also been correlated with radiation dose to the breast skin (radiation telangiectases), and breast tissue (retraction due to fibrosis), the latter depending not only on RT dose but also on the treated boost volume. For this reason, a possible benefit of interstitial implants will only be realized when the gain in local control goes together with minimal cosmetic damage. Therefore, the ballistic advantages of interstitial implants have to be maximally exploited: i.e. the treated volume should be maximally adapted to the target volume, and additional irradiation of the breast skin by the boost technique should be avoided. This paper deals in detail with the technical aspects of breast brachytherapy that seem to be relevant for high quality outcome. (author)

    1999-01-01

    During the last months of Extrap T2 operations an imaging acquisition system, based on charge-coupled devices (CCD) cameras, has been operated. CCD cameras are a standard diagnostic used in many fusion experiments: i) to obtain a direct insight of the plasma behaviour during the pulse, of the evolution of plasma-wall interactions and, eventually, of locked modes, ii) to measure local quantities such as the wall temperature and the impurity influxes, iii) to study the hydrogen recycling behaviour and iv) to estimate the poloidal and toroidal mode numbers. One of the aims of our imaging campaign was to check the utility of such diagnostic for T2. The purpose of this report is to describe the technical aspects involved in the use of such diagnostic and to briefly describe the results obtained. In this view, this report aims to be a guide to the development of a dedicated image acquisition system for Extrap T2, after the planned rebuild, by stressing the problems and limitations encountered during this campaign

Thirteen biotechnological production concepts using the raw materials straw and softwood were established and simulated with the steady state flowsheeting software IPSEpro. Bioethanol production cost and greenhouse gas (GHG) emissions for each system were calculated based on mass and energy balances obtained from process simulation. The emission of GHGs along the entire bioethanol process chain (''from well to wheel'') are compared to two reference systems producing the same amounts of by-products. In all concepts, process heat and considerable amounts of the by-products electricity, heat, pellets, C5 molasses, or biomethane could be obtained from residual biomass. Compared to a reference system driven by fossil energy, GHG emissions can be reduced by up to 76%. The production cost of ethanol was found to between 0.66 EUR and 0.94 EUR per liter of gasoline equivalent. The type and amount of by-product influence technical, economic, and environmental performance significantly. Converting all straw and softwood available in Austria to ethanol would result in an annual production of 340 kt. (orig.)

    To evaluate the technical aspects, results and complications of patients with implanted anterior chest wall port. Between April 1997 and June 1999, a total of 63 implanted ports were placed at the anterior chest wall of 63 consecutive patients by interventional radiologists. The indications were chemotherapy in 61 patients and total parenteral nutrition in two. The peripheral portion of the subclavian vein was punctured under fluoroscopic guidance via ipsilateral peripheral vein during venography. A central venous catheter was placed in the superior vena cava, and using the subcutaneous tunneling method, a connected infusion port was implanted at the anterior chest wall. Results and complications were reviewed, and by means of Kaplan-Meier survival analysis, the expected patency of the port was determined. The technical success rate for implanted port at the anterior chest wall was 100% (63/63 patients). In two patients, hematoma and oozing were treated by compression. The duration of port implantation ranged from 12 to 855 (mean, 187) days, and the port patency rate was 305.7±47.6 days. In seven patients (completed chemotherapy (n=3D3), central venous thrombosis (n=3D3) catheter-related infection (n=3D1)), the port was removed. Catheter obstruction occurred in two patients, and in one, the use of urokinase led to successful recanalization. Sixteen patients died of an underlying malignancy, but no catheter-related death was noted. Implantation of an anterior chest wall port is a safe and useful procedure, with long patency, for patients requiring chemotherapy and long-term venous access. (author)

    Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

    To evaluate the technical aspects, results and complications of the percutaneous radiologic placement of peritoneal dialysis catheters. Between December 1999 and April 2001, 26 peritoneal dialysis catheters were placed percutaneously in 26 consecutive patients by interventional radiologists. The patient group consisted of 16 men and ten women with a mean age of 55 (range, 30-77) years. The results and complications arising were reviewed, and the expected patency of the catheters was determined by means of Kaplan-Meier survival analysis. The technical success rate for catheter placement was 100% (26/26 patients). Severe local bleeding occurred in one patient due to by inferior epigastric artery puncture, and was treated by compression and electronic cautery. The duration of catheter implantation ranged from 1 to 510 days and the patency rate was 416±45 days. Catheter malfunction occurred in four patients. In two, this was restored by manipulation in the intervention room, and in one, through the use of urokinase. In three patients, peritonitis occurred. Catheters were removed from four patients due to malfunction (n=2), peritonitis (n=1), and death (n=1). Percutaneous radiologic placement of a peritoneal dialysis catheter is a relatively simple procedure that reduces the complication rate and improves catheter patency

  19. Preservation of Records, Knowledge and Memory across Generations (RK and M). Monitoring of Geological Disposal Facilities - Technical and Societal Aspects

    International Nuclear Information System (INIS)

    2014-01-01

    The OECD Nuclear Energy Agency (NEA) Radioactive Waste Management Committee (RWMC) Project on 'Preservation of Records, Knowledge and Memory across generations (RK and M)' (2011-2014) explores and aims to develop guidance on regulatory, policy, managerial, and technical aspects of long-term preservation of records, knowledge and memory of deep geological disposal facilities. While official responsibility for the preservation of records, knowledge and memory must remain with institutions, it is likely that local communities do or will have an important pragmatic role in maintaining the memory of a repository, e.g., by engaging at some level in its continued oversight. Monitoring - by collecting, interpreting and keeping data on a continuous basis - would serve the purpose of preserving records, knowledge and memory and continuous oversight. In order to tackle the subject it is important, on the one hand, to describe the role of monitoring in a technical perspective and, on the other, to understand the expectations of local stakeholders regarding monitoring. The present study report should therefore meet three objectives: - To present in a comprehensive way the general monitoring information, practices and approaches used in the various national geological disposal programmes and elaborated in a number of international projects; - To explore the role, needs and expectations of local communities regarding monitoring and RK and M preservation of deep geological repositories; - Based on the above review, to identify lessons learned and the rationale for monitoring geological disposal projects throughout their life-cycle stages. This report is based on two studies: an NEA internal report entitled 'Monitoring of Geological Disposal Facilities (August 2013)' which provides an overview on technical aspects of monitoring and an NEA public report entitled 'Local Communities' Expectations and Demands on Monitoring and the Preservation of Records, Knowledge and Memory of a Deep

    Various techniques and energy-based devices have been used to minimize the blood loss during transection of the liver parenchyma laparoscopically. The laparoscopic Habib™ 4X sealer (Rita Medical Systems, Inc., Fremont, CA) is a promising device using bipolar radiofrequency energy. The purpose of the study was to test the safety and the efficiency of the device in laparoscopic left lateral sectionectomy. Five patients underwent laparoscopic left lateral sectionectomy using the laparoscopic Habib 4X in a period of 12 months. Indications for liver resection were hepatocellular carcinoma in 2 cirrhotic patients and colorectal cancer liver metastasis in 3 patients. Technical aspects were analyzed. All the patients underwent formal laparoscopic left lateral sectionectomy. The Pringle maneuver was not applied in any of the patients. Mean operative time was 75 minutes (range, 60-90 minutes). Bleeding control along the transection line was satisfactory. No conversion to laparotomy was required. Operative blood loss was minimal. No blood transfusion was recorded. The postoperative period was uneventful. Median hospital stay was 3 days (range, 2-5 days). Histopathology revealed that the margins were disease free. Laparoscopic left lateral segmentectomy with the use of Habib 4X proved safe and efficient. This technique may be an initial step for surgeons shifting to laparoscopic liver surgery provided they have previous experience in laparoscopic and liver surgery. Well-designed controlled randomized studies are needed in order to evaluate further the role of the device used in the present study in minimally invasive liver surgery.

    Besides technical aspects and those of safety, it is the economic and social environment of a future underground geologic repository which plays a major role. Compared to other large scale technical plants, facilities for radioactive waste management must overcome incomparably greater obstacles. All the more care must be taken in clarifying the issues affecting the public and the economy in the region of a potential site. On behalf of the Swiss Federal Office for Energy (BFE), Ruetter + Partner conducted a basic study which, in a number of case studies, dealt with the socio-economic aspects of experiences with existing and planned facilities in Switzerland and abroad. The study focused on these main points, which are outlined briefly in the article: - Socio-economic issues in the site selection procedure. - Methodological approach. - Findings made in the case studies. - Factors influencing the acceptance of a repository.

    Full Text Available Laparoscopic liver resection has been performed mostly in centers with an extended expertise in both hepatobiliary and laparoscopic surgery and only in highly selected patients. In order to overcome the obstacles of this technique through improved intraoperative visualization we developed a laparoscopic navigation system (LapAssistent to register pre-operatively reconstructed three-dimensional CT or MRI scans within the intra-operative field. After experimental development of the navigation system, we commenced with the clinical use of navigation-assisted laparoscopic liver surgery in January 2010. In this paper we report the technical aspects of the navigation system and the clinical use in one patient with a large benign adenoma. Preoperative planning data were calculated by Fraunhofer MeVis Bremen, Germany. After calibration of the system including camera, laparoscopic instruments, and the intraoperative ultrasound scanner we registered the surface of the liver. Applying the navigated ultrasound the preoperatively planned resection plane was then overlain with the patient's liver. The laparoscopic navigation system could be used under sterile conditions and it was possible to register and visualize the preoperatively planned resection plane. These first results now have to be validated and certified in a larger patient collective. A nationwide prospective multicenter study (ProNavic I has been conducted and launched.

    Introduction: In a human space mission, the human factor is one of the dominant aspects, which may strongly influence work results and efficiency. To quantify such a difficult and uncontrollable aspect of space missions, it is necessary to reproduce as exactly as possible the environmental and technical conditions in which astronauts may be confronted: limited re-sources, social interactions in an isolated and cramped area… We will take the benefit of the EuroGeoMars campaign in the Mars Desert Research Station (MDRS, Mars Society) in Utah to observe and measure these characteristics. EuroGeoMars campaign: The EuroGeoMars team aims at assessing the development of scientific protocols and techniques in geology and biology research in planetary conditions. In this framework, MRDS simulation constitutes its main achievement. The scientific investigations conducted in MRDS are expected to provide valuable results, beyond the simple reflection on how managing planetary specific conditions. Nevertheless, the different scientific protocols, even tailored for extreme environmental conditions, require an exhaustive analysis to evaluate how the results and their timing may possibly be affected. MDRS: The MDRS habitat will demand the crew members to work in a cramped environment, surrounded by dust and very limited manpower. Moreover, energy power and communication bandwidth will be limited to the crew members. Human aspects and habitat studies: The crewmember will work in an uncomfortable environment in the habitat: dust, cramping and crowd. Moreover, the sustainibility of the mission will relie on an optimal energy and ressources sharing. This will impose a planification of the different investigating activities. The study of the human aspects and habitat will be performed in terms of impact on scientific and technical tasks rather than in terms of crew's comfort. As any astronaut will previously be aware of the daily condition, we want to improve the working conditions

  7. Regulatory aspects of the use of PSA to evaluate technical specifications

    1991-01-01

    Based on experiences gained in PSA activities the regulatory body of the GDR initiated a programme to investigate the feasibility of using PSA for the evaluation of technical specifications. This programme is just under work. In addition, to improve PSA, the GDR takes part in a programme which is aimed at performing plant specific level 1, PSA as well as and which enables operating organizations to carry out PSA on their own. The most important of some preliminary general findings presented in this paper are: - Technical specifications form a well established envelope of operational conditions and procedures. A total re-evaluation is not considered necessary; Probabilistic evaluation of technical specifications should be an integrated part of PSA activities (at least level 1). Single assessment is not considered reasonable; Probabilistic evaluation of technical specifications has to be based on plant specific information and realistic accident sequence calculations; Up to now no quantitative probabilistic criteria for technical specifications have been established.

    Surgical techniques may vary extensively between centers. We report on a web-based survey aimed at evaluating the current technical approaches in different centers around the world performing epilepsy surgery in children. The intention of the survey was to establish technical standards. A request was made to 88 centers to complete a web-based survey comprising 51 questions. There were 14 questions related to general issues, 13 questions investigating the different technical aspects for children undergoing epilepsy surgery, and 24 questions investigating surgical strategies in pediatric epilepsy surgery. Fifty-two centers covering a wide geographic representation completed the questionnaire. The median number of resective procedures per center per year was 47. Some important technical practices appeared (>80% of the responses) such as the use of prophylactic antibiotics (98%), the use of high-speed drills for bone opening (88%), nonresorbable material for bone flap closure (85%), head fixation (90%), use of the surgical microscope (100%), and of free bone flaps. Other questions, such as the use of drains, electrocorticography (ECoG) and preoperative withdrawal of valproate, led to mixed, inconclusive results. Complications were noted in 3.8% of the patients submitted to cortical resection, 9.9% hemispheric surgery, 5% callosotomy, 1.8% depth electrode implantation, 5.9% subdural grids implantation, 11.9% hypothalamic hamartoma resection, 0.9% vagus nerve stimulation (VNS), and 0.5% deep brain stimulation. There were no major differences across regions or countries in any of the subitems above. The present data offer the first overview of the technical aspects of pediatric epilepsy surgery worldwide. Surprisingly, there seem to be more similarities than differences. That aside many of the evaluated issues should be examined by adequately designed multicenter randomized controlled trials (RCTs). Further knowledge on these technical issues might lead to increased

    2015-01-01

    Full Text Available Bridge Management System (BMS represents a rational and systematic approach to organizing and conducting of all activities related to bridge maintenance. Main goal of BMS is helping the bridge owner to make an optimal decision with respect to bridge maintenance budget, whether it is dedicated to one bridge or to group of bridges, by securing that the decision is made on the basis of Life-Cycle Cost (LCC estimates. The structure of BMS is based on condition rating and Bridge Database (BD, Deterioration model (DM, Cost Model for evaluation of costs and Optimization Model for choosing the most rational maintenance strategy. Relationship between bridge condition rating and DM with maintenance costs within BMS is very important. Predictions regarding future intensity and rate of bridge deterioration depends on multitude of factors and it is a consequence of several simultaneous actions and deterioration processes (DP which need to be included into DMs. DMs are mostly based on modeling of physical and chemical actions and processes or they are based on statistical analysis of large number of data regarding the condition of existing bridges, or on artificial intelligence models, etc. Stochastic models based on Markov processes are applied within more advanced contemporary BMS. Due to social and economic circumstances and lack of financial resources over the last two decades in Republic of Serbia bridge maintenance was neglected and creation of BD was discontinued. The paper deliberates some aspects of technical models within BMS, with DMs being pointed out, development of BD within bridge maintenance in Republic of Serbia and it gives an overview of sophisticated BMS and current advances in this field.

    Breast cancer is the major cause of mortality among female population in Serbia. It is presumed that the introduction of screening programme will reduce mortality and therefore, 47 new mammography units were installed for the purpose of population-based screening program in 2011. In parallel, Quality assurance and Quality control (QC) in mammography has received increasing attention as an essential element of the successful breast cancer campaign that is for the first time initialed in Serbia. The purpose of this study is to investigate the need for and the possible implementation of the comprehensive QC programme for the mammography screening in Serbia, with special focus on physical and technical aspect. In the first phase, a QC protocols containing list of parameters, methodology, frequency of tests and reference values for screen-film, computed radiography and full-filed digital mammography) units, were developed. The second phase is focused on the initial implementation of these protocols. The paper presents results of tests of the selected parameters in 35 mammography units, with special emphasis on patient dose and image quality descriptors. After initial implementation at the beginning of the population based breast cancer screening campaign, it is essential to establish system of regular and periodic QC equipment monitoring and to ensure high quality mammograms with minimal possible radiation dose to population included in the screening.

    The Large Aspect Ratio Tokamak Study (LARTS) at Oak Ridge National Laboratory (ORNL) investigated the potential for producing a viable longburn tokamak reactor by enhancing the volt-second capability of the ohmic heating transformer through the use of high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

    The purpose of this work was to assess mammography practice in Serbia and its appropriateness for both diagnostic service and potential screening by implementing quality control (QC) protocol in three large teaching hospitals. Corrective actions were suggested, accordingly. In addition to technical aspects of QC, image quality was assessed using image grading before and after the introduction of corrective measures. The survey demonstrated considerable variations in technical parameters that affect image quality and patients doses. Average glandular doses ranged from 1.8 to 2.8 mGy, while reference optical density (OD) ranged from 1.0 to 2.6. Image grading resulted in a very high percentage of images with poor quality (12-70% for cranio-caudal projection and 8-66% for medio-lateral oblique projection). Main problems were associated with film processing, viewing conditions and OD control. Following introduction of corrective measures, the image grading results were improved in some hospitals, so the percentage of images without any remarks has been increased. (authors)

    The risk of getting contagious illnesses through applying biological tissues has been one of the paramount worries to be solved since infectious illnesses might be provoked by virus, fungi or bacteria coming from donors or whether they have been introduced by means of intermediate stages before the use of these tissues. Therefore it has been concluded that the tissue allograft must be sterilized. The work presented is a Technical and economic Feasibility Study for the creation of a Tissue Bank in Chile, considering the fact of lacking of such institutions in our country and the need to satisfy the population that requires tissues. It is shown the processes involved and the characteristics of a tissue bank, and also a market survey in order to meet the demand, supply, technical requirements, competitors, opportunities and legal aspects of the process. Finally, it was examined the economic feasibility at which defines the investment, financing and business projections to determine the profitability of the project

    Groundwater management has traditionally been observed as a study for long term policy measures to ensure that the water resource is sustainable. IBM Research, in association with the World Bank, extended this traditional analysis to include realtime groundwater management by building a context-aware, water rights management and permitting system. As part of this effort, one of the primary objectives was to develop a groundwater flow model that can help the policy makers with a visual overview of the current groundwater distribution. In addition, the system helps the policy makers simulate a range of scenarios and check the sustainability of the groundwater resource in a given region. The system also enables a license provider to check the effect of the introduction of a new well on the existing wells in the domain as well as the groundwater resource in general. This process simplifies how an engineer will determine if a new well should be approved. Distance to the nearest well neighbors and the maximum decreases in water levels of nearby wells are continually assessed and presented as evidence for an engineer to make the final judgment on approving the permit. The system also facilitates updated insights on the amount of groundwater left in an area and provides advice on how water fees should be structured to balance conservation and economic development goals. In this talk, we will discuss the concept of Digital Aquifer, the challenges in integrating modeling, technical and software aspects to develop a management system that helps policy makers and license providers with a robust decision making tool. We will concentrate on the groundwater model developed using the analytic element method that plays a very important role in the decision making aspects. Finally, the efficiency of this system and methodology is shown through a case study in Laguna Province, Philippines, which was done in collaboration with the National Water Resource Board, Philippines and World

    The Large Aspect Ratio Tokamak Study (LARTS) investigated the potential for producing a viable long burn tokamak reactor through enhanced volt-second capability of the ohmic heating transformer by employing high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were accessed in the context of extended burn operation. Plasma startup and burn parameters were addressed using a one-dimensional transport code. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the field in the ohmic heating coil and the wave shape of the ohmic heating discharge. A high aspect ratio reference reactor was chosen and configured

    Historically, effectiveness of community collaborative prevention efforts has been mixed. Consequently, research has been undertaken to better understand the factors that support their effectiveness; theory and some related empirical research suggests that the provision of technical assistance is one important supporting factor. The current study examines one aspect of technical assistance that may be important in supporting coalition effectiveness, the collaborative relationship between the technical assistance provider and site lead implementer. Four and one-half years of data were collected from technical assistance providers and prevention team members from the 14 community prevention teams involved in the PROSPER project. Spearman correlation analyses with longitudinal data show that the levels of the collaborative relationship during one phase of collaborative team functioning associated with characteristics of internal team functioning in future phases. Results suggest that community collaborative prevention work should consider the collaborative nature of the technical assistance provider - prevention community team relationship when designing and conducting technical assistance activities, and it may be important to continually assess these dynamics to support high quality implementation.

    Positron emission tomography (PET) is indicated for a large number of cardiac diseases: perfusion and viability studies are commonly used to evaluate coronary artery disease; PET can also be used to assess sarcoidosis and endocarditis, as well as to investigate amyloidosis. Furthermore, a hot topic for research is plaque characterization. Most of these studies are technically very challenging. High count rates and short acquisition times characterize perfusion scans while very small targets have to be imaged in inflammation/infection and plaques examinations. Furthermore, cardiac PET suffers from respiratory and cardiac motion blur. Each type of studies has specific requirements from the technical and methodological point of view, thus PET systems with overall high performances are required. Furthermore, in the era of hybrid PET/computed tomography (CT) and PET/Magnetic Resonance Imaging (MRI) systems, the combination of complementary functional and anatomical information can be used to improve diagnosis and prognosis. Moreover, PET images can be qualitatively and quantitatively improved exploiting information from the other modality, using advanced algorithms. In this review we will report the latest technological and methodological innovations for PET cardiac applications, with particular reference to the state of the art of the hybrid PET/CT and PET/MRI. We will also report the most recent advancements in software, from reconstruction algorithms to image processing and analysis programs.

  8. Environmental data quality problems: ''Technical'' vs. ''legal'' defensibility

    1995-01-01

    Two significant aspects of environmental data quality are currently being emphasized throughout the industry as critical precursors to environmental decision making: technical integrity and legal defensibility. Because audit findings and consequent perceptions by a client often pose more questions than answers--especially with respect to the ''systemic'' nature and significance of problems based on nonstatistical, ad hoc sampling of large programs--quality assurance in environmental restoration must do more than implement traditional administrative controls. A major problem persists in achieving a consensus opinion between quality assurance and technical staff on the significance of various data problems. This case study compares and contrasts ''technical integrity'' and ''legal defensibility'', and provides performance measures developed to optimize both components in a large, complex DOE environmental restoration program. Performance measures of both administrative and technical processes are being used to ensure that conclusions drawn concerning ''systematic'' problems are not premature, and are founded on thorough, representative aspects of the program. Improved methods to reach consensus opinions on environmental decision-making are imperative and environmental data quality, the cornerstone on which the decisions are built, must be not only scientifically solid, but perceived as solid, if stakeholders are to be satisfied

    The "TOMAX" (TO MAX-imize sensation, sexuality, and quality of life) procedure restores genital sensation in men with low spinal lesions, improving sexual health, as shown previously. It connects the dorsal nerve of the penis to the intact ipsilateral ilioinguinal nerve, unilaterally or bilaterally. This study reports on the technical aspects based on 43 TOMAX nerve transfers. In 40 patients with no penile but intact groin sensation, 43 nerve transfers were performed. Data on patient selection, surgical history, anatomy of the ilioinguinal nerve and dorsal nerve of the penis, unilateral or bilateral surgery, surgical technique, complications, and patient information were collected prospectively. Regardless of origin, all patients with no penile but good groin sensation are eligible for the procedure, provided the ilioinguinal nerve is not damaged because of former inguinal surgery or absent because of anatomical variations. Selection of a unilateral or bilateral procedure depends on the presence or absence of reflex erections and bulbocavernosus reflex. Preliminary experience with the first three bilateral cases shows that it is technically feasible, with encouraging results. The surgical technique has evolved (described in detail, including video) to enhance outcome and reduce complications. Patients are better informed, resulting in realistic expectations. This article synthesizes the procedural and technical experience of 43 TOMAX nerve transfers. Anyone skilled in peripheral nerve surgery and microsurgery can adopt this concept and further develop it. The TOMAX procedure can then be used to restore erogenous penile sensation and improve the quality of sexual health in patients with absent penile but good groin sensation.

    Besides technical, political and economic aspects of energy sustainability there are several social, behavioural and psychological dimensions of vital importance for a successful implementation of Renewable Energy Systems (RES) and Rational Use of Energy (RUE) within communities. The European Project ''Sustainable Communities-on the energy dimension'' pursues an interdisciplinary approach to detect essential success and facilitating factors. In the last years social and psychological aspects in the process of sustainability came to the fore more and more. Not only as a complementary science to facilitate the technical aims in the change process but also as an essential part for success. (authors)

    2006-01-01

    We present a comparative analysis of technical and economic aspects of ancillary services on the markets of England and Wales, Nordic Countries, California, Argentina, Australia and Spain, comparing the services of voltage control, frequency regulation and system restoration. All the analyzed markets rely on the existence of an administrator of ancillary services, function that leads to the figure of the system operator. Among the services analyzed, the mandatory nature of voltage control and primary frequency regulation stands out, being both the ancillary services with the higher market price and the shortest period of time requirements. In general, the recognized costs of the services correspond to investments operation, maintenance, and opportunity costs. In the provision of these ancillary services, there are no clear preferences for a particular resource allocation mechanism, where mandatory provision, auctions, competitive offers and different time length bilateral contracts are combined

    1989-01-01

    This study was conducted to assess the technical and economic aspects of high level waste (HLW) management with the objective of optimizing the interim storage duration and the dimensions of the underground repository site. The procedure consisted in optimizing the economic criterion under specified constraints. The results are intended to identify trends and guide the choice from among available options; simple and highly flexible models were therefore used in this study, and only nearfield thermal constraints were taken into consideration. Because of the present uncertainty on the physicochemical properties of the repository environment and on the unit cost figures, this study focused on developing a suitable method rather than on obtaining definitive results. With the physical and economic data bases used for the two media investigated (granite and salt) the optimum values found show that it is advisable to minimize the interim storage time, and that the geological repository should feature a high degree of spatial dilution. These results depend to a considerable extent on the assumption of high interim storage costs

    This project is to provide the regulatory direction of 4 major technical issues for the Korean Next Generation Reactors, which are parts of major technical issues resulted from the safety regulation R and D on the KNGR. The outstanding results are are as follows : related to the classification and acceptance criteria of plant conditions, currently used classification and safety requirement were reviewed and regulatory direction was proposed. Among multiple failures, it is identified that SBO, TLOFW, multiple SGTR and ATWS are basically to be considered for additional requirements for advanced reactors. This study reviewed risk aspects, design consideration, and trends of safety requirements, and proposed fundamental safety requirements to be applied for KNGR. Multiple steam generator tube failure is a significant safety concern because of the possibility of release of radionuclides to the environment through containment bypass. Proposed safety requirement for this event can be categorized mainly as analysis requirement, design evaluation requirement and PSA requirement; For protection of containment failure, a reasonable safety position is necessary through and integrated review of possibility of severe accident occurrence, effects of sever accident mitigation features and cost effects of these design features. With this consideration safety requirements developed are the analysis requirement, provision of protective measures and survivability/availability of protective measures.

This eventually aims to secure implicit as well as explicit knowledge and expand domestic specialists for future fusion facilities including K-DEMO. As a part of the project, the comparative analysis and gap study of technical standards and Quality Assurance (QA) system between ITER and Korean nuclear facilities are being performed. The goal of this study is to present a roadmap re-systematizing current safety-related standards for the fission-based facilities into fusion-based facilities in Republic of Korea. The research is considering two different tracks. First one is to secure the state-of-the-art of the fusion technical standards continually updated. For its investigation, we organized the Korean fusion safety advisory group that consists of experts from institutes, industries, and universities. The latest information of technical standards have been gathered and updated from each area of expert in periodic manner. The information is classified into Product Breakdown Structure (PBS) including safety classification, major safety issues, analysis computer codes, etc. This task will be re-organized this year such that the technical standards for procurement as well as non-procurement items can be accumulated in systematic and sustainable manner. Second one, called “Gap Study,” is to compare the requirements for domestic nuclear facilities and the results from the first track on the basis of experts’ opinion from the national and private sectors and to recommend the approaches to overcome technical and administrative barriers.

    Full Text Available Objective: We evaluated knowledge of technical aspects of non-surgical root canal treatment among general dentists in private dental clinics in Al-Madinah Al-Munawarah, Saudi Arabia. Materials and Methods: A questionnaire was distributed randomly to 70 general dental practitioners who were working in private dental centers. The response rate was 88.6%. Results: The results showed that only 3% of dentists were using rubber dams for isolation during endodontic treatment. The majority (59.7% were using radiographs to determine the length. Also, 37% were using nickel-titanium (NiTi rotary instruments to prepare the root canal. The lateral condensation technique with gutta percha points to fill the root canal was used by most respondents (77.5%. Conclusions: This study provides important data on endodontic treatment by general dental practitioners in Al-Madinah Al-Munawarah private dental centers. It shows a general lack of knowledge regarding the importance of using rubber dams as well as the new endodontic materials and methods. Continuing education programs to update their knowledge in the field of endodontics are essential.

    2006-01-01

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper will provide the summary on Nuclear Plant Life Management (PLIM) (or Ageing Management Program (AMP)) and Plant Life Extension (PLEX) development in USA and European countries. Also, insights from such effort currently performing in Slovenia will be discussed.(author)

    Technical and practical aspects of applying geostatistics are developed for individuals involved in investigation at hazardous-, toxic-, and radioactive-waste sites. Important geostatistical concepts, such as variograms and ordinary, universal, and indicator kriging, are described in general terms for introductory purposes and in more detail for practical applications. Variogram modeling using measured ground-water elevation data is described in detail to illustrate principles of stationarity, anisotropy, transformations, and cross validation. Several examples of kriging applications are described using ground-water-level elevations, bedrock elevations, and ground-water-quality data. A review of contemporary literature and selected public domain software associated with geostatistics also is provided, as is a discussion of alternative methods for spatial modeling, including inverse distance weighting, triangulation, splines, trend-surface analysis, and simulation

  8. Geological-Technical and Geo-engineering Aspects of Dimensional Stone Underground Quarrying

    Science.gov (United States)

    Fornaro, Mauro; Lovera, Enrico

    Underground exploitation of dimensional stones is not a novelty, being long since practised, as proved by a number of historical documents and by a certain number of ancient quarrying voids throughout the world. Anyway, so far, open cast quarrying has been the most adopted practice for the excavation of dimensional stones. One primary reason that led to this situation is of course connected to the lower production costs of an open cast exploitation compared to an underground one. This cheapness has been supported by geological and technical motives: on the one hand, the relative availability of surface deposits and, on the other, the development of technologies, which often can be used only outdoor. But, nowadays, general costs of quarrying activities should be re-evaluated because new, and often proper, restrictions have been strongly rising during recent years. As a consequence of both environmental and technical restrictions, pressure will more and more arise to reduce open cast quarrying and to promote underground exploitations. The trend is already well marked for weak rocks - for instance in the extractive basin of Carrara, where about one hundred quarries are active, 30 per cent is working underground, but also in Spain, Portugal and Greece the number of underground marble quarries is increasing - but not yet for hard rock quarrying, where only few quarries are working underground all around the world. One reason has to be found in cutting technologies traditionally used. In weak rocks, diamond wire saw and chain cutter are usable, with few adaptations, in underground spaces, while drilling and blasting, the traditional exploitation method for hard stone, is not easily usable in a confined space, where often only one free face is available. Many technicians and researchers agree that two technologies will probably open the door to underground quarrying in hard rocks: diamond wire and water jet. The first one is already available; the second should still be

    Data on plasma exchange therapy in the intensive care unit (ICU) setting are scarce. We aimed to describe the technical aspects and the adverse events associated with the procedure in critically ill patients. All adult patients treated by plasma exchange in the medical ICU of the Saint-Louis university hospital between January 1, 2013 and March 31, 2015 were prospectively included. We report on 260 plasma exchange procedures performed in 50 patients. The centrifugation technique was used for 159 (61%) procedures and the filtration technique for the other 101 (39%) procedures. Both techniques had similar efficacy to treat hyperviscosity syndrome (n = 18). Seventy (26.9%) of the 260 plasma exchange procedures were reported with at least one adverse reaction. Centrifugation and filtration techniques had similar rates of adverse reactions (23.9 vs. 31.7%, P = .19). Hypotension was the most reported (n = 21, 8%) and correlates with a low hematocrit before therapy. Most complications were related to allergic reactions to the replacement fluids. Coagulation disorders depended on the type of replacement fluid. The post-exchange fibrinogen level was decreased by 54% [48;66] with albumin 5%, and 4% [-5;17] with plasma frozen within 24 h. Twenty-three (22.8%) of the 101 filtration procedures experienced filter clotting. Filter clotting was associated with a higher volume exchange prescribed when compared to procedures without filter clotting (4600 [4000;5000] ml vs. 3900 [3600;4800] ml, P < .01). Plasma exchange is a relatively safe and generally well-tolerated procedure in the ICU setting. Most adverse events are unpredictable and related to minor allergic reactions. © 2017 Wiley Periodicals, Inc.

    There is a growing awareness of the crucial role that urban territories must and can play in reducing greenhouse gas emissions, along with a growing power of a lobby dedicated to supporting the voices of urban territories vis-a-vis national states. The local level of organization and policy is relevant for two main reasons: density and spatial organization are key factors that influence energy consumption in transport and building; some of the major potentials for emission abatement need local coordination to overcome transaction costs. 'Engage, Empower and Resource': this formula, forged during the C40 Seoul Summit (May 2009), calls for clear and quantified commitments with a timetable for delivery; additional power and competencies for cities to increase their capacity to act; and substantial financial resources. Road-Map: This paper identifies key elements that need to be taken into account when developing a road-map that seeks empowerment of local governments in the UN post-2012 framework. It explores political, economic, technical and legal aspects, along with respective main issues to be addressed. (authors)

    2010-01-01

    Full Text Available Mammography is the method of choice for early detection of breast cancer. In Serbia, mammography is performed only clinically, although there is a plan to introduce mammography as a screening method. Currently, there are 60 mammographic units in practice, resulting in 70 000 mammographies annually. The survey was conducted in order to investigate mammographic practice in Serbia, identify weak points and suggest appropriate corrective measures. Basic technical parameters of the X-ray tube and generator, processing, image quality, and patient doses in 20 mammographic units were studied. The survey demonstrated considerable variations in technical parameters that affect image quality, and patients doses. Patient dose levels, in terms of the mean glandular dose, were fairly consistent with current European reference levels: 1.8 (0.40-4.3 mGy. However, due to inappropriate image receptors, image processing and viewing conditions and automatic exposure control adjustment, suboptimal image quality was a common finding. Simple improvements of the radiographic technique and maintenance procedure, along with the rigid implementation of the quality control procedure and training of the operating staff, would improve the performance levels of mammographic practice in Serbia, i. e. result in the production of high quality images with a reasonably low radiation risk to patients.

    2013-01-01

    Full Text Available Confronted with the spectacular evolution of the aircraft and other aerial vehicles, the systems destined to combat them, especially Surface-to-Air Missile Systems (SAMS, went through an accelerated loss of their performance. The financial crisis has forced an extension of the system operation even if the system is outdated. Therefore, a new modernized version has been designed. Many times, it is better to improve an existing system than to buy a new one. This article describes the diversity of SAMS’s challenges, involving a decrease in time regarding their number. The types of challenges can be divided in two categories: technical and institutional ones. The technical challenges can be also divided in two categories: deterioration of material and obsolescence. The classes of material that present interest for us are aerodynamic vector structure, propulsion, and special systems. From an institutional point of view, the main problems are: cost versus performance and cost versus the remaining lifetime (technical resource of the air defense system. The article finishes with conclusions that support the possibility and necessity of a SAMS upgrade, given the change of the threats characteristics.

    2012-01-01

    Waste caused by the use of radioactive material in research, medicine and technologies, above all high level waste from nuclear power plants, must be disposed of safely. However, the strategies discussed for the disposal of radioactive waste as well as proposals for choosing a proper site for final waste disposal are strongly debated. An appropriate disposal must satisfy complex technical requirements and must meet stringent conditions to appropriately protect man and nature from risks of radioactivity over very long periods. Ethical, legal and social conditions must be considered as well. An interdisciplinary team of experts from relevant fields compiled the current status and developed criteria as well as strategies which meet the requirements of safety and security for present and future generations. The study also provides specific recommendations that will improve and optimize the chances for the selection of a repository site implementing the participation of stakeholders including the general public an...

  16. The Gender Dimension of Technical Change and Job Polarisation

    OpenAIRE

    2010-01-01

    Many studies have shown that technical change has led to job polarisation. A relatively unexplored aspect of this is whether there has been a gender bias. This paper is the first to show gender bias in technology driven skill polarisation. Between 1997 and 2006 the demand for women shows hollowing out across high, medium and low education groups, as a consequence of technical change. This was not the case for men. Decomposing the fall in the gender pay gap shows further evidence for gender bi...

    Failures in nontechnical and teamwork skills frequently lie at the heart of harm and near-misses in the operating room (OR). The purpose of this systematic review was to assess the impact of nontechnical skills on technical performance in surgery. MEDLINE, EMBASE, PsycINFO databases were searched, and 2,041 articles were identified. After limits were applied, 341 articles were retrieved for evaluation. Of these, 28 articles were accepted for this review. Data were extracted from the articles regarding sample population, study design and setting, measures of nontechnical skills and technical performance, study findings, and limitations. Of the 28 articles that met inclusion criteria, 21 articles assessed the impact of surgeons' nontechnical skills on their technical performance. The evidence suggests that receiving feedback and effectively coping with stressful events in the OR has a beneficial impact on certain aspects of technical performance. Conversely, increased levels of fatigue are associated with detriments to surgical skill. One article assessed the impact of anesthesiologists' nontechnical skills on anesthetic technical performance, finding a strong positive correlation between the 2 skill sets. Finally, 6 articles assessed the impact of multiple nontechnical skills of the entire OR team on surgical performance. A strong relationship between teamwork failure and technical error was empirically demonstrated in these studies. Evidence suggests that certain nontechnical aspects of performance can enhance or, if lacking, contribute to deterioration of surgeons' technical performance. The precise extent of this effect remains to be elucidated. Copyright © 2012 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    Sweet, Robert M; Hananel, David; Lawrenz, Frances

    2010-02-01

    To present modern educational psychology theory and apply these concepts to validity and reliability of surgical skills training and assessment. In a series of cross-disciplinary meetings, we applied a unified approach of behavioral science principles and theory to medical technical skills education given the recent advances in the theories in the field of behavioral psychology and statistics. While validation of the individual simulation tools is important, it is only one piece of a multimodal curriculum that in and of itself deserves examination and study. We propose concurrent validation throughout the design of simulation-based curriculum rather than once it is complete. We embrace the concept that validity and curriculum development are interdependent, ongoing processes that are never truly complete. Individual predictive, construct, content, and face validity aspects should not be considered separately but as interdependent and complementary toward an end application. Such an approach could help guide our acceptance and appropriate application of these exciting new training and assessment tools for technical skills training in medicine.

    Nowadays application of new and renewable energy as main resource of power plant has greatly increased. High penetration of renewable energy into the grid will influence the quality and reliability of the electricity system, due to the intermittent characteristic of new and renewable energy resources. Smart grid or microgrid technology has the ability to deal with this intermittent characteristic especially if these renewable energy resources integrated to grid in large scale, so it can improve the reliability and efficiency of the grid. We plan to implement smart microgrid system at Sekolah Tinggi Teknik PLN as a pilot project. Before the pilot project start, the feasibility study must be conducted. In this feasibility study, the renewable energy resources and load characteristic at the site will be measured. Then the technical aspect of this feasibility study will be analyzed. This paper explains that analysis of ths feasibility study.

    Black liquor gasification (BLG) is one of the high-prioritized RandD areas in Sweden. Research work is going on in the national program BLG-Programme. The main aims with the present study are to: - Identify larger projects dealing with energy oriented system aspects of BLG - Make a synthesis on system aspects results in these projects - Identify need for further work, e.g. as a part of a second period of the BLG Programme. No new work or calculations have been performed, the aim has been only to compile and draw conclusions from existing information. The focus has been on system studies. Most of the research on BLG has been technically, chemically and component oriented. These areas are not included in this report. In Chapter 2 basics for BLG are presented and in Chapter 3 important system aspects of this technology are discussed. Future opportunities for energy savings in mills are crucial for a BLG system, both technically and economically. Therefore present knowledge for such opportunities is presented in Chapter 4. In section 1.4 the report/projects included in this report are introduced and in Chapter 5-13 Summaries, especially on system aspects, of these reports are given. In order to keep the report at a reasonable size only major projects dealing with system aspects during the last 10 year period have been included. In Chapter 14 a synthesis of system aspects dealt with in the different reports is presented and in Chapter 15 suggestions for further work are given. In Chapter 16 references are given and finally in the Attachment a brief overview of different BLG technologies is presented

  7. Reader-Centered Technical Writing

    2012-12-01

    Technical writing is an essential part of professional communication and in recent years it has shifted from a genre-based approach. Formerly, technical writing primarily focused on generating templates of documents and sometimes it was creating or reproducing traditional forms with minor modifications and updates. Now, technical writing looks at the situations surrounding the need to write. This involves deep thinking about the goals and objectives of the project on hand. Furthermore, one observes that it is very important for any participatory process to have the full support of management. This support needs to be well understood and believed by employees. Professional writing may be very persuasive in some cases. When presented in the appropriate context, technical writing can persuade a company to improve work conditions ensuring employee safety and timely production. However, one must recognize that lot of professional writing still continues to make use of reports and instruction manuals. Normally, technical and professional writing addresses four aspects. Objective: The need for generating a given professionally written technical document and the goals the document is expected to achieve and accomplish. Clientele: The clientele who will utilize the technical document. This may include the people in the organization. This may also include "unintended readers." Customers: The population that may be affected by the content of the technical document generated. This includes the stakeholders who will be influenced. Environment: The background in which the document is created. Also, the nature of the situation that warranted the generation of the document. Swiss Psychologist Jean Piaget's view of Learning focuses on three aspects. The author likes to extend Jean Piaget's ideas to students, who are asked to prepare and submit Reader-Centered Technical Writing reports and exercises. Assimilation: Writers may benefit specifically, by assimilating a new object into

  8. Determining significance in social impact assessments (SIA) by applying both technical and participatory approaches: Methodology development and application in a case study of the concentrated solar power plant NOORO I in Morocco

    2017-01-01

    One of the main objectives of impact assessments is to identify potentially significant impacts. However, determining this significance has received very limited attention as a procedural step in social impact assessments. Consequently, only limited research and documentation exists on approaches, survey tools and evaluation methods, especially with regard to participatory approaches and combined participatory-technical approaches. This study aims to address this research gap by developing and applying a joined participatory and technical impact significance evaluation. The approach is applied in a case study which analysed the livelihood impacts of the large-scale concentrated solar power plant NOOR O I in Ouarzazate, Morocco. The analysis shows that although different approaches and significance criteria must be applied when involving both local stakeholders and experts, the linked analysis offers more robust results and an improved basis for decision-making. Furthermore, it was observed in the case study that impacts affecting the social, cultural and political spheres were more often considered significant than impacts affecting the physical and material livelihood dimensions. Regarding sustainability assessments of large-scale renewable energy plants, these findings underline the importance (as for other large-scale infrastructure developments) of placing greater emphasis on the inclusion of social aspects in impact assessments. - Highlights: •Significance evaluation in social impact assessments lacks participatory aspects. •Combined participatory and technical impact significance evaluation developed •Application in a case study to analyse the livelihood impacts of a CSP plant •Involvement of local stakeholders and technical experts results in robust findings. •Social, cultural and political issues are often more relevant than material aspects.

    2013-12-01

    The da Vinci robotic surgical telemanipulator has been utilized in several surgical specialties for varied procedures, and the users' experiences have been widely published. To date, no detailed system technical analyses have been performed. A detailed review was performed of all publications and patents about the technical aspects of the da Vinci robotic system. Published technical literature on the da Vinci system highlight strengths and weaknesses of the robot design. While the system facilitates complex surgical operations and has a low malfunction rate, the lack of haptic (especially tactile) feedback and collisions between the robotic arms remain the major limitations of the system. Accurate, preplanned positioning of access ports is essential. Knowledge of the technical aspects of the da Vinci robot is important for optimal use. We confirmed the excellent system functionality and ease of use for surgeons without an engineering background. Research and development of the surgical robot has been predominant in the literature. Future trends address robot miniaturization and intelligent control design. Copyright © 2012 John Wiley & Sons, Ltd.

    The emission of sulfur dioxide (SO 2 , also SO 3 ) and nitrogen oxides (NO, NO 2 , called NO x ) from fossil fuel burning power and industrial plants is one of the major sources of environmental pollution. These pollutants are named as acid gases causing acid rain and also indirect greenhouse gases contributing greenhouse effect. Acid rain damages forest, agriculture fields and flora, and cause public health concerns in regions having a number of industrial plants. Today, many countries have started to impose industrial emission limits and this movement has generated renewed interest in finding viable and cost effective solutions to SO 2 and NO x pollution control. The conventional technologies, wet scrubbing de-SO 2 and de-NO x , now reached their full potential therefore these methods are not expected to provide further improvements in terms of efficiency or reduction in construction costs. However, new technologies are being investigated for industrial scale commercial viability. One of them is electron beam process, which is dry scrubbing process and simultaneously removes SO 2 and NO x , and useful by-product for agriculture fertilizer. In this study, the economical and technical aspects of electron beam flue gas treatment process are discussed. Because an electron accelerator facility with electron beam energy of 500 KeV and electron beam current of 20 mA will be installed at ANRTC in TURKEY

    2014-01-01

    Full Text Available Previous researches have proved the positive effect of creative human capital and its development on the development of economy. Yet, the technical efficiency of creative human capital and its effects are still under research. The authors are trying to estimate the technical efficiency value in Chinese context, which is adjusted by the environmental variables and statistical noises, by establishing a three-stage data envelopment analysis model, using data from 2003 to 2010. The research results indicate that, in this period, the entirety of creative human capital in China and the technical efficiency value in different regions and different provinces is still in the low level and could be promoted. Otherwise, technical non-efficiency is mostly derived from the scale nonefficiency and rarely affected by pure technical efficiency. The research also examines environmental variables’ marked effects on the technical efficiency, and it shows that different environmental variables differ in the aspect of their own effects. The expansion of the scale of education, development of healthy environment, growth of GDP, development of skill training, and population migration could reduce the input of creative human capital and promote the technical efficiency, while development of trade and institutional change, on the contrary, would block the input of creative human capital and the promotion the technical efficiency.

    The purpose of the Technical Committee Meeting (TCM) was to provide the opportunity to review the status of design and development activities associated with safety related and economic aspects of HTGRs, and to identify pathways which may provide the opportunity for international cooperation in addressing these issues. The HTGR, as a nuclear heat source for the safe, economic and efficient production of electricity and high temperature industrial processes has, within the past few years, become a significantly increasing influence in the future of nuclear power. Nuclear test facilities with the capability of achieving core outlet temperatures to 950 deg. C are presently under construction in China and Japan. These plants will be utilized to support HTGR research and development activities, including electricity generation via the gas turbine and validation of high temperature process heat applications. Also, major development programmes focusing on the generation of electricity through the direct cycle gas turbine are in progress by ESKOM, the state electric utility of South Africa, and by a consortium of organizations from the Russian Federation, USA, France and Japan. Other national programmes focusing on research and development of the HTGR are underway including the Netherlands, where an evaluation is being completed on a heat and power co-generation plant utilizing a small direct cycle HTR; in Germany, where the primary focus is centered on basic issues of reactor safety and innovative reactor technology; in Indonesia with the evaluation of process heat applications such as coal liquefaction, hydrogen production and high temperature reforming of methane; and in the USA with the recent re-introduction of national support for the HTGR specifically directed to the burning of weapons plutonium. The status information presented in several of the papers is as of the time of drafting. Thus other later material should be referenced for more current status information

    This comprehensive article summarises the commercial aspects of a study made by the German Association of Electrical, Electronic and Information Technologies VDE on the topic of decentralised energy supply in the year 2020. In a previous article, the technical aspects were examined. This article looks at the findings in connection with commercial aspects of the production of power in decentralised facilities including those using renewable sources of energy. The potential of these forms of electricity generation for the year 2020 is looked at both from the political and economical points of view. The general conditions prevailing for the implementation of decentralised power production in Germany such as the Renewable Energy Law and legislation on combined heat and power generation are discussed. The influence of electricity tariffs and competition in the market is examined, as are various scenarios and concepts for the supply of both power and heating energy. Ways of providing a sustainable energy supply without having to subsidise particular concepts are discussed

    The purpose of this study was to investigate the intersurgeon variation in technical aspects of performing an arthroscopic Bankart repair. A unique approach with experienced equipment representatives from 3 different arthroscopic companies was used. Experienced representatives were identified by DePuy Mitek, Smith & Nephew, and Arthrex and filled out questionnaires on how their surgeons performed arthroscopic Bankart procedures. This was performed in a blinded fashion with no knowledge of the identities of the specific surgeons or representatives by us. A video on different aspects of the procedure was observed by each representative before filling out the questionnaire to help standardize responses. Data were collected using REDCap (Research Electronic Data Capture). Data were analyzed as an infrequent observation with 0% to 30% of representatives reporting the observation; sometimes, 31% to 70% reporting the observation; and often, greater than 70% of representatives reporting. Seventy-six percent of representatives had 6 or more years of arthroscopic experience. Forty-three percent of representatives reported that their surgeons use 3 portals for the procedure often. Forty-four percent reported that viewing was performed exclusively from the posterior portal while the surgeon was performing the repair. Seventy-three percent reported that the Hill-Sachs lesion was observed often, and 61% reported that the posterior labrum was evaluated often before the repair. Only 25% of representatives reported that the Bankart lesion was extensively released and mobilized often. Thirty-three percent reported 3 anchors as being used often. Seventy-five percent reported biocomposite anchors as being used often. Single-loaded anchors were reported as being used often by 47%. Eighty-one percent reported that sutures were placed in a simple fashion. Eighty-three percent reported the use of any posterior sutures or anchors for additional plication as infrequent. There is significant

    New Perspectives on Technical Editing by Avon J. Murphy (ed.) ISBN : 978-0895033949 (2010) Baywood Publishing Company Inc, Hardcover, 210 pages, 35.5 GBP This book presents a collection of 10 chapters dealing with diverse aspects of technical editing (ie, editorial planning, and analysis and structural changes made to other people's technological documents): research in technical editing, trends and teaching of technical editing, copyediting, and technical journal editing. The role and function of the modern journal and book editor is also dealt with in detail. Each chapter is written by an expert in the field: senior editors, university professors in technical communication, technical writers and linguists. The ever-evolving role of the editor is clearly elucidated in several historical reviews, and in the descriptions of the expectations for the future. A very striking aspect of this book is its extensive collection of bibliographic resources: every chapter lists dozens of very useful references, and the closing chapter, and annotated bibliography, contain many not so well known references, and are most useful. All in all, the book is a treasure trove listing more than 400 references, in addition to numerous webpage URLs embedded in the texts. The book is designed to help the reader to understand current practices and norms in technical editing, and to help to take action in editing as well as in teaching and educating would-be editors. The audience for this book thus includes editors and teachers, but also writers, researchers and students. A deep reading of this book will result in a better understanding of the difference between full technical editing and its much narrower component so well known as copyediting, and will convince any prospective editor that editing should not be undertaken if the people involved do not master the art of precision and accuracy in technical (as well as in human) communication, do not possess the technical know how and computer

    Full Text Available Regina Sorrentino, Roberta Esposito, Enrica Pezzullo, Maurizio Galderisi Department of Advanced Biomedical Sciences, Interdepartmental Laboratory of Cardiac Imaging, Federico II University Hospital, Naples, Italy Abstract: Three-dimensional speckle tracking echocardiography (3D STE is a novel technique for the quantification of cardiac deformation based on tracking of ultrasonic speckles in gray scale full-volume 3D images. Developments in ultrasound technologies have made 3D speckle tracking widely available. Two-dimensional echocardiography has intrinsic limitations regarding estimation of left ventricular (LV volumes, ejection fraction, and LV mechanics, due to its inherent foreshortening errors and dependency on geometric models. The development of 3D echocardiography has improved reproducibility and accuracy. Data regarding the feasibility, accuracy, and clinical applications of 3D STE are rapidly assembling. From the tracking results, 3D STE derives several parameters, including longitudinal, circumferential and radial strain, as well as a combined assessment of longitudinal and circumferential strain, termed area strain. 3D STE can also quantify LV rotational movements such as rotation, twist, and torsion. 3D STE provides a better insight on global and regional myocardial deformation. Main applications include detection of subclinical myocardial involvement in heart failure, arterial hypertension, dyssynchrony, and ischemic heart disease. Emerging areas of application include a large spectrum of heart-involving systemic conditions, such as prediction of rejection in heart transplant patients, early detection of cardiotoxicity in patients receiving chemotherapy for cancer, and deeper physiological understanding of LV contraction mechanics in different types of athletes. Aim of this review is to discuss background, technical acquisition and processing aspects as well as recognized and developing clinical applications of this emerging

    2016-01-01

    What is technical democracy? And why does it matter for urban studies? As an introduction to this special feature, we address these questions by reflecting on To Our Friends, the 2014 manifesto of the Invisible Committee. We engage in particular its provocative diagnosis of the current situation......: power no longer resides in the modern institutions of representative democracy and the market economy; instead, power has become a matter of logistics, infrastructures and expertise. This diagnosis, we suggest, brings into view the challenge of technical democracy, that is, the democratization of techno......-scientific expertise and the instauration of forms of lasting collaboration among experts and laypeople. Urban politics, we claim, increasingly turns around socio-technical controversies and it is in terms of the politics of expertise that we should analyse and engage it.

    Full Text Available ABSTRACT Objective: The aim of the present study was to define normative data of phrenic nerve conduction parameters of a healthy population. Methods: Phrenic nerve conduction studies were performed in 27 healthy volunteers. Results: The normative limits for expiratory phrenic nerve compound muscle action potential were: amplitude (0.47 mv - 0.83 mv, latency (5.74 ms - 7.10 ms, area (6.20 ms/mv - 7.20 ms/mv and duration (18.30 ms - 20.96 ms. Inspiratory normative limits were: amplitude (0.67 mv - 1.11 mv, latency (5.90 ms - 6.34 ms, area (5.62 ms/mv - 6.72 ms/mv and duration (13.77 ms - 15.37 ms. Conclusion: The best point of phrenic nerve stimulus in the neck varies among individuals between the medial and lateral border of the clavicular head of the sternocleidomastoid muscle and stimulation of both sites, then choosing the best phrenic nerve response, seems to be the appropriate procedure.

    Yoon, J. W.

    1998-01-01

    In the post-Cold War era, the threats of horizontal nuclear proliferation emerge as the forefront security issue while the nuclear arms races among existing nuclear weapon states reduce to a remarkable extent. In this context, there arises lots of research attention to the IAEA nuclear safeguards which have been viewed as the core of international monitoring on the clandestine nuclear activities of potential proliferators. However, previous attention tended to highlight the political aspects of the IAEA nuclear safeguards, centering on the possibilities and limitations of the IAEA's inspection authority. In contrast, this paper purports to focus on the technical aspects of the IAEA nuclear safeguards, so it can show the intrinsic problems of those safeguards in stemming the proliferation of nuclear weapons. This paper mainly deals with the technical objectives and options of the IAEA nuclear safeguards, the technical indices of clandestine nuclear activities, and some measures to improve the efficacy of the IAEA nuclear safeguards. Hopefully, this paper is expected to lead us to approach the issue of the North Korean nuclear transparency from the technical perspective as well as the political one

    Genetically modified animals are state of the art in biomedical research as gene therapy is a promising perspective in the attempt to cure hereditary diseases. Both approaches have in common that modified or corrected genetic information must be transferred into cells in general or into particular cell types of an organism. Here we give an overview of established and emerging methods of transfection and gene delivery and provide conceptual and technical advantages and drawbacks of their particular use. Additionally, based on a flow chart, we compiled a rough guideline to choose a gene transfer method for a particular field of application. Copyright © 2015 Elsevier Ltd. All rights reserved.

    1981-01-01

    It is suggested that engineers and other technical students be taught three classes of skills in technical writing. First, "Big Picture Things", which includes: the importance of clear writing, the wide scope of writing, the wide scope of writing tasks that will be faced in industry, and the principles of organization of technical materials such as; how to analyze, classify, partition, and interpret. Second, "Writing Procedures", which encompasses: how to get words on paper efficiently and team-write. Third, "Writing Details", in which two considerations are important: how to achieve precision in the use of language and the aspects of style. Three problems in style are cited: the problem of sentence transition, overuse of attributive adjectives, and verbosity in paragraph structure. The most important thing in technical writing is considered to be functionality, economy and clarity.

    A fusion research project was evaluated from the aspects of socio-economics and its possible economic benefit. Research project itself has large economic impacts and it appears in a different way in different time. Four categories were identified as such mechanisms; direct economic effect by purchase and employment, the growth of local community and its economy, an improvement of technical capability of the industry stimulated by the development, and fusion energy supply under environmental constraints. Industrial effects were analysed from actual R and D program and found to yield considerable economic outcome, although contribution by the research itself is far smaller than that required for industry before actual commercial products can be produced. Economic value of fusion energy could be huge, but appears several decades future, and should be reduced by discount rate and success probability. Its value is more important as a part of environmental policy. Value of the fusion research at present age cannot be estimated as actual benefit, but as the effectiveness in the policy, or benefit for public that is now regarded as a kind of Externality

    2017-12-01

    Full Text Available At present, the organization of transportation by rail is associated with the processing of trains and wagons along the route. Accommodation and equipping of technical stations play a major role in the organization of the transportation process. The uninterrupted operation of the technical stations ensures the stability of the railway transport as a whole. The distance between the technical stations determines the duration of operation of the locomotive crew, the efficient use of the locomotive, the required number of locomotive crews and locomotives for carrying out the transportation plan, and also improves the main indicators of the railway. However, often train locomotives do not fulfill their assigned tasks due to the lack of time for the locomotive crew in order to deliver the train to the nearest technical station, as well as the irrational use of the standard time of the locomotive crew. In connection with the expectation of delivery, the locomotive brigade replacing the locomotive, the idle time of the wagons at the intermediate stations increases. All this makes it difficult to control the movement of trains and reduces the speed of moving cars on the railway transport. The purpose of the study is to develop a method for placing technical stations on a railway test site in the course of an electric traction. To achieve this goal, it will be necessary to solve the following tasks: generalization of the main parameters of the location of technical stations; determination of half-races between technical stations in the operation of one locomotive brigade; search for the required number of change of the locomotive brigade; determination of the distance between technical stations. The methods of research are based on the generalization and analysis of existing results in finding the rational location of technical stations. Results: It is revealed that the first step for the rational placement of technical stations is to determine the

    This report discusses treatment of mixed wastes which is thought to be more complicated than treatment of either hazardous or radioactive wastes. In fact, the treatment itself is no more complicated: however, the regulations that define acceptability of the final waste disposal system are significantly more entangled, and sometimes in apparent conflict. This session explores the factors that influence the choice of waste treatment technologies, and expands on some of the limitations to their application. The objective of the presentation is to describe the technical factors that influence potential treatment processes and the ramifications associated with particular selections (for example, the generation of secondary waste streams). These collectively provide a framework for making informed treatment process selections

    The polymerase chain reaction (PCR) is an effective method for in vitro DNA amplification which combined with probing with synthetic oligonucleotides can be used for, e.g., HLA-typing. We have studied the technical aspects of HLA-DP typing with the technique. DNA from mononuclear nucleated cells...... was extracted with either a simple salting out method or phenol/chloroform. Both DNAs could be readily used for PCR. The MgC2 concentration of the PCR buffer and the annealing temperature of the thermal cycle of the PCR were the two most important variables. The MgCl2 concentration and the temperature must...... be carefully titrated for each primer pair in the PCR. The influence of mismatches between the primer and the DNA template were studied and we found that, by using primers differing only from each other at the 3' end, cross-amplification of closely homologous alleles could be avoided.

    Hepatic cell transplantation consists of grafting already differentiated cells such as hepatocytes. Human hepatocytes are viable and functionally active. Liver cell transplantation is carried out by means of a 3-step method: isolation of hepatocytes from donor liver rejected for orthotopic transplantation, preparing a cell suspension for infusion and, finally, hepatocytes are implanted into the recipient. There are established protocols for the isolation of human hepatocytes from unused segments of donor livers, based on collagenase digestion of cannulated liver tissue at 37 degrees C. The hepatocytes can be used fresh or cryopreserved. Cryopreservation of isolated human hepatocytes would then be available for planned use. In cell transplant, the important aspects are: infusion route, number of cells, number of infusions and viability of the cells. The cells are infused into the patient through a catheter inserted via portal vein or splenic artery. Liver cell transplantation allows liver tissue to be used that would, otherwise, be discarded, enabling multiple patients to be treated with hepatocytes from a single tissue donor.

    Several studies have projected a massive increase in the demand for air conditioners (ACs) over the next two decades in India. By 2030, room ACs could add 140 GW to the peak load, equivalent to over 30% of the total projected peak load. Therefore, there is significant interest among policymakers, regulators, and utilities in managing room AC demand by enhancing energy efficiency. Building on the historical success of the Indian Bureau of Energy Efficiency’s star-labeling program, Energy Efficiency Services Limited recently announced a program to accelerate the sale of efficient room ACs using bulk procurement, similar to their successful UJALA light-emitting diode (LED) bulk procurement program. This report discusses some of the key considerations in designing a bulk procurement or financial incentive program for enhancing room AC efficiency in India. We draw upon our previous research to demonstrate the overall technical potential and price impact of room AC efficiency improvement and its technical feasibility in India. We also discuss the importance of using low global warming potential (GWP) refrigerants and smart AC equipment that is demand response (DR) ready.

    1977-01-01

    In this paper, we discuss some design aspects of transuranic field studies. Some of the principal steps in the design of such studies are given and illustrated using examples. This is followed by a review of sampling designs that have been used at nuclear detonation and safety-shot sites on the Nevada Test Site and elsewhere for estimating spatial pattern and total amounts in soil. Some design aspects of ecosystem-type transuranic studies for estimating total amounts as well as movement of transuranics between ecosystem components are also discussed. Acceptance sampling using either attributes or measurements is considered as a possible approach for deciding whether to clean up a contaminated site. Three general guidelines for the design of efficient transuranic studies are presented

    Full Text Available Sometimes we wonder. Why practitioners of recreational physical activities do not make systematic use of a particular sports facility ?, Why some sports facility remains almost always empty? Why it is continued unnecessarily reversed large sums of material resources for maintenance? For the simple reason that sports facilities were from the beginning that were not well conceived and designed architecturally, where among other things, not sporting habits and population size of the place properly examined. Similarly, we have witnessed criteria issued regarding the performance of a specific sports field, far from contributing to the extension and improvement of the practice of recreational physical and sports activities in its various manifestations, its null or poor continuous maintenance contributing negatively to limit the sporting life and lacerate mental and physical welfare of the inhabitants of the environment.

  7. Overview of clustered nuclear siting and its technical aspects

    International Nuclear Information System (INIS)

    Meier, P.M.

    1976-09-01

    In recent years there has been growing discussion over the ability of new siting approaches to redress the increasing problems of nuclear plant location. This debate has focused largely on three alternatives to the conventional siting of nuclear reactors; floating offshore plants; underground siting; and nuclear energy centers (NECs) consisting of up to 40 reactors at a single site, and, possibly, including fuel cycle facilities within their perimeter. Congressional interest in energy centers, especially in view of concern over the proliferation of nuclear reactors throughout the country, and with the special problems of safeguards over fuel reprocessing and the use of plutonium as a reactor fuel, resulted in a mandate to the Nuclear Regulatory Commission to make a comprehensive analysis of the energy center concept. A common finding of all of the studies of the nuclear energy center concept thus far is that there appear to be no technical considerations that would clearly preclude energy centers. With the one significant exception regarding the meteorological impacts of the concentration of heat and moisture releases to the atmosphere, engineering solutions would appear to be quite adequate to address any difficulties of environmental impact, electrical systems management, water supply or construction management, and to keep the overall physical environmental impact of an energy center not significantly different to that of an equivalent number of dispersed reactors

No matter how far the optimization of oxygen input with aerobic waste water purification advances it will still be the less a real competitor for anaerobic techniques the more polluted the waste water is. The principle of carrier fixation to avoid their washing out, too, has often been observed in nature with sessile microorganisms. With highly polluted water, anaerobic purification does not only work at no expenditure of energy but it can also make excess energy available for use in other processes. Another important argument for anaerobic methods of waste water purification is probably the clearly reduced production of excess sludge. (orig.) [de

    To explore the experiences of family carers who manage technical health procedures at home and describe their learning process. A qualitative study using grounded theory. New Zealand family carers (21 women, 5 men) who managed technical health procedures such as enteral feeding, peritoneal dialysis, tracheostomy care, a central venous line or urinary catheter. In addition, 15 health professionals involved in teaching carers were interviewed. Semistructured interviews were coded soon after completion and preliminary analysis influenced subsequent interviews. Additional data were compared with existing material and as analysis proceeded, initial codes were grouped into higher order concepts until a core concept was described. Interviewing continued until no new ideas emerged and concepts were well defined. The response of carers to the role of managing technical health procedures in the home is presented in terms of five dispositions: (1) Embracing care, (2) Resisting, (3) Reluctant acceptance, (4) Relinquishing and (5) Being overwhelmed. These dispositions were not static and carers commonly changed between them. Embracing care included cognitive understanding of the purpose and benefits of a procedure; accepting a 'technical' solution; practical management; and an emotional response. Accepting embrace is primarily motivated by perceived benefits for the recipient. It may also be driven by a lack of alternatives. Resisting or reluctant acceptance results from a lack of understanding about the procedure or willingness to manage it. Carers need adequate support to avoid becoming overwhelmed, and there are times when it is appropriate to encourage them to relinquish care for the sake of their own needs. The concept of embracing care encourages health professionals to extend their attention beyond simply the practical aspects of technical procedures to assessing and addressing carers' emotional and behavioural responses to health technology during the training process

    2003-07-01

    This report describes the results of one of a series of studies commissioned by the UK Department of Trade and Industry into various aspects of embedded generation with the aim of supporting the development and deployment of electrical sources (particularly their ease of connection to the network) to deliver power to consumers. The first phase of the project involved a literature review and meetings with embedded generation developers and planning engineers from distribution network operators (DNOs). The second phase investigated embedded generation at different levels of the distribution network and included modelling a representative network. Technologies that could facilitate a significant increase in embedded generation were identified and estimates made of when and where significant development would be needed. Technical problems identified by DNOs were concerned with thermal loading, voltage regulation, fault levels, protection and network operation. A number of non-technical (commercial and regulatory) problems were also identified. The report describes the UK regulatory framework, the present situation, the British power system, the accommodation of embedded generation by established means, the representative model and technical innovations.

    Modularity has gained an increasing popularity as a central concept for exploring product structure, process structure, organization structure and supply chain structure. With the offset in system theory the predominant understanding of modularity however faces difficulties in explaining the social...... dimension of modularity like irrational behaviors, cultural differences, learning processes, social organization and institutional influences on modularity. The paper addresses this gab offering a reinterpretation of the modularity concept from a socio-technical perspective in general and Actor Network...... Theory in particular. By formulating modularity from an ANT perspective covering social, material and process aspects, the modularity of a socio-technical system can be understood as an entanglement of product, process, organizational and institutional modularity. The theoretical framework is illustrated...

    Riem, N; Boet, S; Bould, M D; Tavares, W; Naik, V N

    2012-11-01

    Both technical skills (TS) and non-technical skills (NTS) are key to ensuring patient safety in acute care practice and effective crisis management. These skills are often taught and assessed separately. We hypothesized that TS and NTS are not independent of each other, and we aimed to evaluate the relationship between TS and NTS during a simulated intraoperative crisis scenario. This study was a retrospective analysis of performances from a previously published work. After institutional ethics approval, 50 anaesthesiology residents managed a simulated crisis scenario of an intraoperative cardiac arrest secondary to a malignant arrhythmia. We used a modified Delphi approach to design a TS checklist, specific for the management of a malignant arrhythmia requiring defibrillation. All scenarios were recorded. Each performance was analysed by four independent experts. For each performance, two experts independently rated the technical performance using the TS checklist, and two other experts independently rated NTS using the Anaesthetists' Non-Technical Skills score. TS and NTS were significantly correlated to each other (r=0.45, P<0.05). During a simulated 5 min resuscitation requiring crisis resource management, our results indicate that TS and NTS are related to one another. This research provides the basis for future studies evaluating the nature of this relationship, the influence of NTS training on the performance of TS, and to determine whether NTS are generic and transferrable between crises that require different TS.

    Joo, CH, Hwang-Bo, K, and Jee, H. Technical and physical activities of small-sided games in young Korean soccer players. J Strength Cond Res 30(8): 2164-2173, 2016-The aim of this study was to examine the technical aspects and physical demands during small-sided games (SSGs) with different sized pitches in young Korean soccer players. Participants were randomly selected during a nationally held youth competition. Three different game formats were used: SSG8 (8 vs. 8 played on a small-sized field [68 × 47 m]), RSG8 (8 vs. 8 played on a regular-sized field [75 × 47 m]), and RSG11 (11 vs. 11 played on a regular-sized field). Eleven technical (ball touches, passes, and shots) and 6 physical demand variables (exercise frequency by intensity) were observed and analyzed. Same variables were also analyzed for the goalkeepers. As a result, SSG8 and RSG8 showed significantly greater numbers of technical plays in 5 and 4 variables in comparison to RSG11, respectively. In addition, although the exercise intensities increased slightly in both SSG formats, the amount was within the similar range as previous reports. In conclusion, the SSGs with reduced number of players may be referred in young players to effectively train them in technical aspects of the game by allowing greater ball exposure time without excessive physical demands. Various confounding factors such as pitch dimension should be carefully considered for training specific technical and physical variables in young Korean players.

    1987-01-01

    In this paper, aspects of technical specifications relating to Generic Issues B-56 and B-61 are discussed from a risk-standpoint. These primarily deal with the risk issues associated with (1) adaptive diesel test requirements/surveillance test intervals, and (2) the effectiveness of cumulative outage time requirements for controlling downtime risk. Risk and reliability approaches are presented which (1) allow risk-acceptable test intervals to be determined for any diesel and (2) show the potential risk-control capability of prescribed allowed cumulative outage times. This work was conducted through NRC's Procedures for Evaluating Technical Specifications (PETS) Program. The overall objective of this program is to develop and demonstrate methodologies that utilize risk insights and reliability techniques for evaluating the scope, detailed requirements, and safety impact of plant technical specifications

  5. Case studies: Risk-based analysis of technical specifications

    International Nuclear Information System (INIS)

    Wagner, D.P.; Minton, L.A.; Gaertner, J.P.

    1987-01-01

    The SOCRATES computer program uses the results of a Probabilistic Risk Assessment (PRA) or a system level risk analysis to calculate changes in risk due to changes in the surveillance test interval and/or the allowed outage time stated in the technical specification. The computer program can accommodate various testing strategies (such as staggered or simultaneous testing) to allow modeling of component testing as it is carried out at a plant. The methods and computer program are an integral part of a larger decision process aimed at determining benefits from technical specification changes. These benefits can include cost savings to the utilities by reducing forced shutdowns with no adverse impacts on risk. Three summaries of case study applications are included to demonstrate the types of results that can be achieved through risk-based evaluation of technical specifications. (orig.)

    The topic of energy crops, namely of those crops designed to produce biomass to transform into ethanol, has been explored, in Italy and abroad, in all its technical and agronomical aspects. The microeconomic aspect, including the evaluation of convenience for the farmer in adopting such crops, is, on the contrary, less well researched. RENAGRI has developed a research methodology able to give information about the level of convenience of two energy crops (Sweet Sorghum and Topinambour) and has applied it to different Italian agricultural situations, in order to verify the existence of conditions favourable to the cultivation of the two crops, or to indicate the necessity of eventual subvention.

    This report summarizes the review work to paraphrase nuclear technical terms with clear and brief explanations. Explanation with nuclear technical terms was not very acceptable to the public in a variety of contexts. The objective of this study is not to paraphrase with the expert's ideas but to paraphrase from the public point of view. Japan Atomic Energy Agency (hereafter abbreviated as 'JAEA') has conducted a survey on public attitudes toward fifty-nine nuclear technical terms by using an online questionnaire. Most of them were frequently used in the brochures of Nuclear fuel Cycle Engineering Laboratories of JAEA. The survey clarified the public awareness and comprehension of each term. Thirty-two terms, which was subject to paraphrase on a priority basis, were selected from fifty-nine nuclear technical terms based on our importance rating. At the work to paraphrase thirty-two terms, emphasis was placed more on clearness and briefness than on scientific/technical accuracy. They are reviewed through focus group interviews. This study brought results on recognizable style and thirty-two well-polished paraphrases. (author)

  6. Requirements on the provisional safety analyses and technical comparison of safety measures

    International Nuclear Information System (INIS)

    2010-04-01

    The concept of a Geological Underground Repository (SGT) was adopted by the Swiss Federal Council on April 2 nd , 2008. It fixes the goals and the safety technical criteria as well as the procedures for the choice of the site for an underground repository. Those responsible for waste management evaluate possible site regions according to the present status of geological knowledge and based on the safety criteria defined in SGT as well as on technical feasibility. In a first step, they propose geological repository sites for high level (HAA) and for low and intermediate level (SMA) radioactive wastes and justify their choice in a report delivered to the Swiss Federal Office of Energy. The Swiss Federal Council reviews the choices presented and, in the case of positive evaluation, approves them and considers them as an initial orientation. In a second step, based on the possible sites according to step 1, the waste management institution responsible has to reduce the repositories chosen for HAA and SMA by taking into account safety aspects, technical feasibility as well as space planning and socio-economical aspects. In making this choice, safety aspects have the highest priority. The criteria used for the evaluation in the first step have to be defined using provisional quantitative safety analyses. On the basis of the whole appraisal, including space planning and socio-economical aspects, those responsible for waste management propose at least two repository sites for HAA- and SMA-waste. Their selection is then reviewed by the authorities and, in the case of a positive assesment, the selection is taken as an intermediate result. The remaining sites are further studied to examine site choice and the delivery of a request for a design license. If necessary, the requested geological knowledge has to be confirmed by new investigations. Based on the results of the choosing process and a positive evaluation by the safety authorities, the Swiss Federal Council has to

    We describe the technical aspects and report our clinical experience of a surgical approach to the infratemporal fossa that aims to reduce local recurrence after operations for cancer of the posterior maxilla. We tested the technique by operating on 3 cadavers and then used the approach in 16 patients who had posterolateral maxillectomy for disease that arose on the maxillary alveolus or junction of the hard and soft palate (maxillary group), and in 19 who had resection of the masticatory compartment and central skull base for advanced sinonasal cancer (sinonasal group). Early proximal ligation of the maxillary artery was achieved in all but one of the 35 patients. Access to the infratemporal fossa enabled division of the pterygoid muscles and pterygoid processes under direct vision in all cases. No patient in the maxillary group had local recurrence at median follow up of 36 months. Four patients (21%) in the sinonasal group had local recurrence at median follow up of 27 months. Secondary haemorrhage from the cavernous segment of the internal carotid artery resulted in the only perioperative death. The anterolateral corridor approach enables controlled resection of tumours that extend into the masticatory compartment. Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons.

    The interest in distributed energy system has been increasing in China in recent years due to the environmental and energy policy concerns. The distributed energy system generates power, heating and cooling to residential, commercial and industrial facilities. Due to cascade utilization of energy, it can make good use of energy to improve energy efficiency and to increase energy savings. Furthermore, it consumes less energy and reduces carbon emissions. This paper reviews existing and newly-built gas-fired distributed energy projects in China. The techno-economic assessment of the selected projects has also been discussed and reported. The results show that in Xiamen Jimei DE project, the primary energy ratio of the DES can be as high as 92.9%, and energy-saving rate is 35.5%. Moreover, exergy efficiency reaches 54.3%, and the system can reduce 0.52 million tons of CO 2 annually. -- Highlights: ► The political, technical and economical aspects of gas-fired DES are analyzed. ► The techno-economic assessment of two selected projects is conducted. ► Primary energy ratio can be as high as 92.9% and energy-saving rate is 35.5%. ► Exergy efficiency is 54.3% and the system can reduce a large amount of CO 2 emissions

    2010-07-01

    The main purpose of this study was to examine the technical efficiency of farms producing sunflower in Erzurum, Turkey and to identify factors that might be causing inefficiency. Stochastic frontier analysis was used to measure technical efficiency. One hundred and seventeen randomly selected farms were interviewed for farm-level data in the 2004-2005 production period. Results revealed that the mean technical efficiency for the sunflower farms, estimated by the stochastic production frontier, is 64%. At full technical efficiency, on average, the farmers could reduce their inputs by around 56% without reducing their sunflower production, simply by improving technical efficiency. In the inefficiency model the parameter estimates showed that older farmers, higher level of farmer's education, more experienced farmers, larger farm size and higher information score resulted in lower technical inefficiency, while bigger family size and more credit usage resulted in higher technical inefficiency. This study proposes strategies such as providing better extension services and farmer-training programmes, including more educated people in sunflower farming and also expanding the sunflower-growing area through provision of adequate facilities in order to increase technical efficiency.

    In the recent years the fuel cells have received much attention. Among various technologies, the Proton Exchange Membrane Fuel Cell (PEMFC) is currently the most appropriate and is used in several vehicles prototype. A comparative technical, economical and ecological analysis between an Internal Combustion Engine fueled with Diesel driving an electricity Generator (ICE-G) and a PEMFC fed by hydrogen produced by ethanol steam reforming was performed. The technical analysis showed the advantages of the PEMFC in comparison to the ICE-G based in energetic and exergetic aspects. The economic analysis shows that fuel cells are not economic competitive when compared to internal combustion engine driving an electricity generator with the same generation capacity; it will only be economically feasible in a long term; due to the large investments required. The environmental analysis was based on concepts of CO 2 equivalent, pollution indicator and ecological efficiency. Different to the ICE-G system, the Fuel Cell does not emit pollutants directly and the emission related to this technology is linked mainly with hydrogen production. The ecological efficiency of PEMFC was 96% considering the carbon dioxide cycle, for ICE-G system this parameter reach 51%. -- Highlights: • The exergetic efficiency of ICE-G was 22% and for the fuel cell was 40%. • The PEM fuel cell at long-term become economically competitive compared to ICE-G. • The ecological efficiency of PEM fuel cell was 96% and Diesel ICE-G was 51%

    2013-01-01

    There is wide agreement in the literature that non-technical factors play a decisive role in the successful implementation of bioenergy projects. One underlying reason is that such projects require the involvement of many stakeholders, such as feedstock producers, engineers, authorities and the concerned public. We analyze the role of bioenergy-specific non-technical factors for the success of bioenergy projects. In a broad literature review we first identify potential success factors belonging to the five dimensions project characteristics, policy framework, regional integration, public perception and stakeholders. Using these factors as conceptual framework, we next analyze six Japanese pilot projects for bioenergy utilization supported by Japans Agriculture, Forestry and Fisheries Research Council. We apply Rough Set Analysis, a data mining method that can be used for small sample sizes to identify patterns in a dataset. We find that, by and large, non-technical factors from all five dimensions – such as the stability of the local policy framework – co-occur with project success. Furthermore, we show that there are diverging interpretations as to what success in a bioenergy project means. This requires tradeoffs between various goals, which should be identified and addressed explicitly at early stages of such a project. - Highlights: • We collect a broad list of non-technical success factors for bioenergy projects. • These are applied to six pilot projects in Japan and shown to be relevant. • We acknowledge different aspects of project success and their potential conflicts

    2017-12-01

    The paper presents the problem of excessive air pollution in Poland caused mainly by low emission. The emission arises in result of heating flats by means of old and energetically inefficient heating installations. In Poland and Bulgaria the inhaled air is of the worst quality out of all EU countries. The paper presents economic and technical problems related to low emission occurring during the combustion of solid fuels in local boiler houses. Furthermore, the most significant economic issues, connected with the reduction of low emission are discussed, as well as technological possibilities of efficient reduction of the amount of pollution in the atmosphere. Conclusions are presented at the end of the article.

    The results of several studies suggest that spatial ability can be improved through direct training with tasks similar to those integrated in the tests used to measure the ability. However, there is a greater interest in analyzing the effectiveness of indirect training such as games or of learning subjects that involve spatial processes to a certain extent. Thus, the objective of the present study was to analyze whether the indirect training in Technical Drawing improved the Spatial Visualization ability of Architecture students. For this purpose, a group of students enrolled in Fundamentals of Architecture were administered two tests, a Spatial Visualization task and an Abstract Reasoning task, at the beginning and the end of a semester, after having received training through the subjects "Technical Drawing I: Geometry and Perception" and "Projects I." The results of this group were compared with those of a control group of students enrolled in a Mathematics degree, who were also pre-post evaluated but had not received the training in Technical Drawing. The study showed a significant pre-post improvement in both, Visualization and reasoning. However, this improvement occurred in both groups, thereby concluding that this improvement was not due to indirect training. Furthermore, no significant differences were found between men and women in any of the groups or conditions. These results clarify those of an earlier study where improvement in Visualization after training in Technical Drawing was found but did not include a comparison with a control condition. The control condition has proved to be important in order to consider the limitations of the effect of Technical Drawing on said improvement.

    Questions about the sense of life and the responsibility of technology are ethical questions. Young people in our neighbourhood who, compared to some time ago, see, hear and read much more of the world, deal with them increasingly. However, the permanent stream of information does not at all facilitate orientation but prevents many people from gaining some clearness about their own point of view. In asking the questions: where are we today. How can we get on. How can we start. The relation between ethics and technics is discussed under various aspects. (orig./HSCH) [de

  3. Case study on the role of socio-technical influences on the implementation and success of nuclear power in France

    Jedani, T.

    2004-01-01

    To fully understand a technological development one must appreciate social, political and economic factors in addition to the technological components (Hughes, 1991). The systems perspective, asserted by Hughes, implies that technologies cannot be understood in isolation, but only in their contexts, especially in their systemic contexts. This theory is illustrated through an examination of France's implementation of its nuclear power program in the early 1970's. Nuclear power provided France with the opportunity to achieve energy independence and, as a result, political control over its energy supply. The scope of this case study is limited to consideration of the socio-technical influences on the rise of nuclear power in France and includes an examination of the technical aspects of the innovation. In considering the socio-technical system encompassing France's adoption of nuclear power, this case study will contemplate: how France was able to persuade its people to accept nuclear power; what it is about French culture and politics that allowed them to succeed where most other countries have failed; the breakthroughs that led to the broad commercialization of nuclear power in France in the 1970's; and how France achieved its status as one of the world's top producers of nuclear energy. The time period during which this study is based is limited to the early 1970's, when France was reliant upon external energy supplies, up until the present day, where nuclear power has become France's main source of energy, thus contributing to France's autonomy in terms of its energy supply. This study will not address the issue of nuclear waste or the nuclear power safety debate which is also beyond the scope of this study. (author)

    1999-01-01

    In 1993 the Dutch Government issued the official statement that geological storage of high toxic waste (among which radioactive waste) will only be permitted under the condition of retrievability. This boundary condition opened a wide variety of new aspects. Not only of technical and safety nature but also meant a stimulant to reopen the social-ethical debate, not in the least because retrievability offered a variety of objectives to be purchased. The rigid political ordination with respect to retrievability was induced by two former technical reports, one of the Council for Environmental and Nature Research named 'On top or deep down' and a second carried out by the Delft Technical University Mining Faculty, ordered by the 'Research Commission for Radioactive Waste Disposal'. Both reports concluded that in rock salt - at that time the chosen host rock in the Netherlands - a retrievable option was feasible. The report from the Delft University concluded that a period of 100 years was almost certain to be guaranteed, most likely considerably longer in conjunction with maintenance capacities. Since 1995 the new Research Commission on Radioactive Waste Disposal has focussed its activities very clearly on two subjects, retrievability and clay, the latter as an alternative host rock. Besides a series of technical aspects with respect to the retrievable option, much attention was paid to the strategic consequences of this option. In the first place the question of which objectives can be purchased. Seven major objectives were identified, which are: 1. Removal in case of unexpected calamities; 2. Removal - eventually of waste with special characteristics - in order to subject to transmutation processes; 3. Removal in favour of economical reuse; 4. Monitoring to validate the results of modelling studies and other computations in a 'one to one' situation in space and time in the original geological and mining-technical setting; 5. To redesign details of the mining concept

    Minimally invasive urology is rapidly advancing, and single-site laparoscopic surgery is being explored clinically. Such laparoscopic procedures are technically challenging and require an experienced laparoscopic surgeon due to the lack of port placement triangulation and instrument clashing. In the last years several surgeons all over the world have explored the feasibility and safety of LESS using several and different ports, approaches and devices. Hundreds of procedures have been described with overall favorable intraoperative and postoperative outcomes. Our experience consists of more than 30 procedures successfully completed for adrenal, kidney disease and varicocele. To date, LESS could be considered feasible and effective using currently available devices, however it is to be considered as an initial status technique requiring further confirmatory studies and advanced laparoscopic skills.

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    Full text: Present political, economical and social development the world - wide and in particular countries and regions facilitate number of serious and dangerous challenges for people responsible for security of materials and facilities, which could be used as a threat to the humankind in case of unauthorized approach. A number of factors have impact on the security including political, social, financial and technical nature. The security of nuclear materials and facilities where nuclear materials located and under processing is facing a number of problems such as control of the personnel who is handling the materials, access to the materials and the facilities, accounting and control of the materials storage, transportation, transactions, processing, physical protection of the materials. Each aspect of those problems must be taken into account for establishing most efficient way to keep the nuclear materials out of hands of the terrorists. Technical aspects which require serious and intent relation from political and technical communities in Russia (as example) are the following: legal base for nuclear materials protection, control and accounting and export control; personnel for nuclear materials control and accounting - skill, reliability, responsibility, training and new generation education; personnel for physical protection - skill, reliability, responsibility, training; structure of the system and equipment for materials control, verification, accountability; structure of the system and equipment for physical protection; regulatory supervision of the MPC+A system effectiveness.

    Japan has systematically revamped its technical standards for nuclear reactor facilities by formulating various performance regulations. Being part of a trend toward deregulation, such efforts toward social regulation is aimed at effectively operating administrative procedural laws to keep pace with global trends and enhance the benefits of deregulation under the principle of self-responsibility. Based on the collection of public opinions in February and March 2005, the Nuclear and Industrial Safety Agency(NISA) presented its position that it was required to promptly perform a flexible assessment of the technical feasibility of formulated society and association standards. Current, pressing issues are summarized as an early revision of technical standards regarding nuclear facilities for power generation, use of society and association standards, and the overhaul of nuclear safety regulations subject to performance regulations. Subjecting technical standards to performance regulations means stipulating the qualitative aspects of performance and the targets that certain facilities must achieve, which are not specific standards, but general compulsory standards. This study examines the early revision of technical standards on nuclear facilities for power generation and the status of the use of society and association standards, as well as introducing the details of revisions in the concrete containment vessel standards as specific examples

    Objectives: Surgical appraisal and revalidation are key components of good surgical practice and training. Assessing technical skills in a structured manner is still not widely used. Laparoscopic surgery also requires the surgeon to be competent in technological aspects of the operation. Methods: Checklists for generic, specific technical, and technological skills for laparoscopic cholecystectomies were constructed. Two surgeons with >12 years postgraduate surgical experience assessed each operation blindly and independently on DVD. The technological skills were assessed in the operating room. Results: One hundred operations were analyzed. Eight trainees and 10 consultant surgeons were recruited. No adverse events occurred due to technical or technological skills. Mean interrater reliability was kappa=0.88, P=technical and technological skills between trainee and consultant surgeons were significant, Mann-Whitney P=technical and technological skills can be measured to assess performance of laparoscopic surgeons. This technical and technological assessment tool for laparoscopic surgery seems to have face, content, concurrent, and construct validities and could be modified and applied to any laparoscopic operation. The tool has the possibility of being used in surgical training and appraisal. We aim to modify and apply this tool to advanced laparoscopic operations. PMID:17212881

    Full Text Available The integration of photovoltaic (PV generators in the envelope of a building by means of building-integrated photovoltaics (BIPV offers an immense potential, both in market development and the production of renewable electric energy that is close to the point of electricity consumption. In Germany, for example, by integrating photovoltaics in buildings up to 50% of the electricity demand can be covered. The political support of BIPV would contribute to the development and installation of BIPV components and therefore also promote the development of new business areas for industries dealing with components used in building envelopes and photovoltaic generators. BIPV can be separated into three different integration types: “technical”, “formal” and “technical & formal”. Political instruments for the support of PV-installations, particularly BIPV are discussed in this paper using Germany and France as examples. Due to successful financial support policies, PV became the most powerful electricity production technology in Germany. In France, the unique financial support of BIPV is resulting in an exemplary development and growth of certified BIPV components available on the market and, from a technical, aesthetic architectural and legal certainty point of view, facilitating the easy and widespread integration of photovoltaic generators in buildings.

  6. Economic and technical feasibility study of compressed air storage

    Energy Technology Data Exchange (ETDEWEB)

    1976-03-01

    The results of a study of the economic and technical feasibility of compressed air energy storage (CAES) are presented. The study, which concentrated primarily on the application of underground air storage with combustion turbines, consisted of two phases. In the first phase a general assessment of the technical alternatives, economic characteristics and the institutional constraints associated with underground storage of compressed air for utility peaking application was carried out. The goal of this assessment was to identify potential barrier problems and to define the incentive for the implementation of compressed air storage. In the second phase, the general conclusions of the assessment were tested by carrying out the conceptual design of a CAES plant at two specific sites, and a program of further work indicated by the assessment study was formulated. The conceptual design of a CAES plant employing storage in an aquifer and that of a plant employing storage in a conventionally excavated cavern employing a water leg to maintain constant pressure are shown. Recommendations for further work, as well as directions of future turbo-machinery development, are made. It is concluded that compressed air storage is technically feasible for off-peak energy storage, and, depending on site conditions, CAES plants may be favored over simple cycle turbine plants to meet peak demands.

    Piezoelectric materials have found wide applications in technical systems. Most often, a combination of piezoelectric and other materials is advantageous. The position and the amount of the piezoelectric material within the overall system depends on various aspects, such as the maximum mechanical output to the load, the maximum electromechanical efficiency of the system, the maximum utilization of the piezoelectric material, the minimum self-heating of the piezoelectric material, and the controllability of the system, which might be key aspects for the optimization of the system design. For a composite longitudinal vibrator (bolted Langevin transducer), which is a base for many technical applications, this contribution shows in detail, how the above-mentioned aspects depend on the position and the volume of the piezoelectric material related to the mode shape.

    2009-01-01

    The management of technical plant for productivity and safety is generally a complex activity, particularly when many plants distributed in the territory are considered (i.e. the more and more frequent case of outsourced plants maintenance by specialized companies), granted quality and cost results are required (i.e. the case of some rather innovative contract solutions) and the technology involved is heterogeneous and innovative (i.e. electro-mechanical plants). In order to efficiently achieve the above aims an 'intelligent' maintenance-management system for the distant monitoring and controlling by a remote control center has been developed. The so-called GrAMS (granted availability management system) system is conceived to give to organizations involved in technical-industrial plants management the possibility to tend to a 'well-known availability' and 'zero-failures' management. In particular, this study deals with the diagnostic aspects and safety level of technical plants (such as elevators, thermo-technical plants, etc.), and with the involvement of ad hoc designed software analysis tools based on neural networks and reliability indicators. Part of the research dealing with the tele-maintenance intelligent system has been financed by the Italian High Institute for Safety (ISPESL) and led to the development of a pre-industrial prototype whose realization and testing is here described

    To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a. m. to 6:30 p. m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. 62 (95 %) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69 %) mainly caused by suboptimal positioning of patient or eye lense protection. Motion artefacts were observed in 8 exams (12 %). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues. (orig.)

    The operating theatre is a unique environment with complex team interactions, where technical and non-technical performance affect patient outcomes. The correlation between technical and non-technical performance, however, remains underinvestigated. The purpose of this study was to explore these interactions in the operating theatre. A prospective single-centre observational study was conducted at a tertiary academic medical centre. One surgeon and three fellows participated as main operators. All patients who underwent a laparoscopic Roux-en-Y gastric bypass and had the procedures captured using the Operating Room Black Box ® platform were included. Technical assessment was performed using the Objective Structured Assessment of Technical Skills and Generic Error Rating Tool instruments. For non-technical assessment, the Non-Technical Skills for Surgeons (NOTSS) and Scrub Practitioners' List of Intraoperative Non-Technical Skills (SPLINTS) tools were used. Spearman rank-order correlation and N-gram statistics were conducted. Fifty-six patients were included in the study and 90 procedural steps (gastrojejunostomy and jejunojejunostomy) were analysed. There was a moderate to strong correlation between technical adverse events (r s  = 0·417-0·687), rectifications (r s  = 0·380-0·768) and non-technical performance of the surgical and nursing teams (NOTSS and SPLINTS). N-gram statistics showed that after technical errors, events and prior rectifications, the staff surgeon and the scrub nurse exhibited the most positive non-technical behaviours, irrespective of operator (staff surgeon or fellow). This study demonstrated that technical and non-technical performances are related, on both an individual and a team level. Valuable data can be obtained around intraoperative errors, events and rectifications. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

    The purpose of process monitoring using a quality and technical surveillance program was to help ensure that manufactured clad went sets fully met technical and quality requirements established by the manufacturer and the customer and that line and program management were immediately alerted if any aspect of the manufacturing activities drifted out of acceptable limits. The quality and technical surveillance program provided a planned, scheduled approach to monitor key processes and documentation and certification systems to prevent noncompliances or any manufacturing discrepancies. These surveillances illuminated potential problem areas early enough to permit timely corrective actions to reverse negative trends that, if left uncorrected, could have resulted in deficient hardware. Significant schedule and cost impacts were eliminated. copyright 1995 American Institute of Physics

    Legislative and regulatory documentation define responsibilities in the field of security and physical protection for transportation of nuclear material. Any transportation activity has to conform to an advance authorization regime delivered by the Ministry of Industry. Responsibility for physical protection of nuclear material rests with the carrier under control of the public authority. Penalties reinforce this administrative regime. Operational responsibility for management and control of transport operations has been entrusted by the ministry to the operational transport unit (Echelon Operationnel des Transports - EOT) of IPSN (Institute for Nuclear Protection and Safety). To guarantee en efficient protection of transport operations, the various following means are provided for: -specialized transport means; - devices for real time tracking of road vehicles; - administrative authorization and declaration procedures; -intervention capacities in case of sabotage... This set of technical means and administrative measures is completed by the existence of a body of inspectors who may control every step of the operations. (authors). 3 tabs

  1. TECHNICAL RISK RATING OF DOE ENVIRONMENTAL PROJECTS - 9153

    International Nuclear Information System (INIS)

    Cercy, M.; Fayfich, Ronald; Schneider, Steven P.

    2008-01-01

    The U.S. Department of Energy's Office of Environmental Management (DOE-EM) was established to achieve the safe and compliant disposition of legacy wastes and facilities from defense nuclear applications. The scope of work is diverse, with projects ranging from single acquisitions to collections of projects and operations that span several decades and costs from hundreds of millions to billions US$. The need to be able to manage and understand the technical risks from the project to senior management level has been recognized as an enabler to successfully completing the mission. In 2008, DOE-EM developed the Technical Risk Rating as a new method to assist in managing technical risk based on specific criteria. The Technical Risk Rating, and the criteria used to determine the rating, provides a mechanism to foster open, meaningful communication between the Federal Project Directors and DOE-EM management concerning project technical risks. Four indicators (technical maturity, risk urgency, handling difficulty and resolution path) are used to focus attention on the issues and key aspects related to the risks. Pressing risk issues are brought to the forefront, keeping DOE-EM management informed and engaged such that they fully understand risk impact. Use of the Technical Risk Rating and criteria during reviews provides the Federal Project Directors the opportunity to openly discuss the most significant risks and assists in the management of technical risks across the portfolio of DOE-EM projects. Technical Risk Ratings can be applied to all projects in government and private industry. This paper will present the methodology and criteria for Technical Risk Ratings, and provide specific examples from DOE-EM projects

    A survey of engineers and scientists concerning the format of NASA technical reports indicates that a summary as well as an abstract should be included, that the definitions of symbols and glossary of terms should be located in the front of the report, and that the illustrative material should be integrated with the text rather than grouped at the end of the report. Citation of references by number, one-column, ragged-right-margin layout, and third-person writing style are also preferred by a majority of the respondents. The preferences of managers and nonmanagers are very similar for all aspects of technical report format covered by the survey.

    The number of offensive actions and glycolytic energy in combat sports both increase with caffeine (CAF) ingestion. In addition, the effects of CAF on technical-tactical and time-motion analysis and physiological parameters in boxing are unknown. This study aimed to investigate the effects of CAF ingestion on physiological parameters and the notational analysis of boxing matches. Ten male boxers were recruited; the participants ingested 6 mg kg -1 BM of CAF or placebo (PLA) 30 min prior to the match in a crossover design. Heart rate (HR) and rate of perceived exertion (RPE) were collected before and after each of three 2 min rounds, interspersed by 1-min recovery; the matches were recorded for notational analysis. A two-way ANOVA for repeated measures was used for the physiological variables, and a three-way ANOVA with repeated measures was used for technical-tactical and time-motion variables. Statistical differences were found for HR and RPE between rounds (F (6, 54)  = 131.3, p = .001; [Formula: see text] = 0.93 and F (2, 18)  = 40.6, p = .001; [Formula: see text] = 0.81, respectively) but not between conditions (F (1, 9)  = 0.46; p = .51; [Formula: see text] = 0.05 and F (1, 9)  = 0.02, p = .89; [Formula: see text] = 0.002, respectively). The CAF condition induced a greater duration of interaction blocks (CAF = 6.5 ± 1.8 s; PLA = 4.4 ± 0.9 s; p = .01). Effort:pause ratio was 4.4 s:8.7 s (approx. 1:2) for PLA and 6.5 s:9.4 s (1:1.44) for CAF, which were significantly different (p boxing matches induces a greater duration of high-intensity actions, with no effects on internal load markers.

    Prompt Gamma Neutron Activation analysis (PGNAA) is a type of neutron activation analysis which can determined element with nearly no gamma ray decay after being irradiated by neutron sourced. Thus, element that cannot be determined by the conventional NAA for example H, B, N, Si and Cd, can be determine by PGNAA. This paper focuses on the technical working procedure for operating portable PGNAA in field work. The device is designed as a portable non-destructive investigation tool applying an isotopic neutron source (Cf-252) and a gamma-ray spectroscopy system for in-situ investigation. The studied have been carried out on Terengganu inscribed stone at Terengganu State Museum. (author)

  7. Sustaining Open Source Communities through Hackathons - An Example from the ASPECT Community

    2016-12-01

    The ecosystem surrounding a successful scientific open source software package combines both social and technical aspects. Much thought has been given to the technology side of writing sustainable software for large infrastructure projects and software libraries, but less about building the human capacity to perpetuate scientific software used in computational modeling. One effective format for building capacity is regular multi-day hackathons. Scientific hackathons bring together a group of science domain users and scientific software contributors to make progress on a specific software package. Innovation comes through the chance to work with established and new collaborations. Especially in the domain sciences with small communities, hackathons give geographically distributed scientists an opportunity to connect face-to-face. They foster lively discussions amongst scientists with different expertise, promote new collaborations, and increase transparency in both the technical and scientific aspects of code development. ASPECT is an open source, parallel, extensible finite element code to simulate thermal convection, that began development in 2011 under the Computational Infrastructure for Geodynamics. ASPECT hackathons for the past 3 years have grown the number of authors to >50, training new code maintainers in the process. Hackathons begin with leaders establishing project-specific conventions for development, demonstrating the workflow for code contributions, and reviewing relevant technical skills. Each hackathon expands the developer community. Over 20 scientists add >6,000 lines of code during the >1 week event. Participants grow comfortable contributing to the repository and over half continue to contribute afterwards. A high return rate of participants ensures continuity and stability of the group as well as mentoring for novice members. We hope to build other software communities on this model, but anticipate each to bring their own unique challenges.

    A series of groundwater technical procedures documents (GWPDs) has been released by the U.S. Geological Survey, Water-Resources Discipline, for general use by the public. These technical procedures were written in response to the need for standardized technical procedures of many aspects of groundwater science, including site and measuring-point establishment, measurement of water levels, and measurement of well discharge. The techniques are described in the GWPDs in concise language and are accompanied by necessary figures and tables derived from cited manuals, reports, and other documents. Because a goal of this series of procedures is to remain current with the state of the science, and because procedures change over time, this report is released in an online format only. As new procedures are developed and released, they will be linked to this document.

  18. Quality aspects of thermal coal marketing

    International Nuclear Information System (INIS)

    Dunstone, D.

    1998-01-01

    Australia's thermal coal industry is under increasing competition. A successful marketing strategy must distinguish the product from that of Australian competitors, leaving the buyer in no doubt as to its value. The marketing of thermal coal is a very different experience and encompasses an interesting commercial and technical mix. The technical merits of a coal may be effectively used to prepare the way for a sale. However, once the technical hurdle is passed (i.e. the coal is classified as acceptable), the three factors which influence the sale are price, price and price. The other aspect of marketing is that marketing, especially technical market support, must realize that the buyer often has no experience in using the coals purchased. This is particularly true with thermal coals. Virtually no thought is given as to how the coal performs or how much is used. Consequently, it is not uncommon for cheap, low quality coals to be purchased, even though it is not the choice that will result in the lowest power generation cost when all other factors are taken into consideration. The author has developed a model which allows to differentiate between coals for a range of properties relative to the use of the coal, so that a coal company can calculate the break-even price in term of cost per kWh of electricity generated and enable a more valid cost comparison between coals to be made

  19. Safety Aspects in Radioactive Waste Management

    Directory of Open Access Journals (Sweden)

    Peter W. Brennecke

    2007-01-01

    Full Text Available In recent years, within the framework of national as well as international programmes, notable advances and considerable experience have been reached, particularly in minimising of the production of radioactive wastes, conditioning and disposal of short-lived, low and intermediate level waste, vitrification of fission product solutions on an industrial scale and engineered storage of long-lived high level wastes, i.e. vitrified waste and spent nuclear fuel. Based on such results, near-surface repositories have successfully been operated in many countries. In contrast to that, the disposal of high level radioactive waste is still a scientific and technical challenge in many countries using the nuclear power for the electricity generation. Siting, planning and construction of repositories for the high level wastes in geological formations are gradually advancing. The site selection, the evaluation of feasible sites as well as the development of safety cases and performance of site-specific safety assessments are essential in preparing the realization of such a repository. In addition to the scientific-technical areas, issues regarding economical, environmental, ethical and political aspects have been considered increasingly during the last years. Taking differences in the national approaches, practices and the constraints into account, it is to be recognised that future developments and decisions will have to be extended in order to include further important aspects and, finally, to enhance the acceptance and confidence in the safety-related planning work as well as in the proposed radioactive waste management and disposal solutions.

    The lack of success, not to say failure, of seismic microzonation projects in the Latin America and Caribbean nations-and for that matter elsewhere in the world-should not be attributed to the lack of technical and scientific expertise of our engineers and scientists as there exists in our continent sufficient knowledge and information about the techniques and procedures that have been successfully used elsewhere in the world in the implementation of seismic microzonation projects. The main constrains to the implementation of seismic microzonation projects in Latin America and the Caribbean are of an economic, social, political, and cultural aspects rather than the purely scientific and engineering aspects. Another very important factor contributing to this lack of success has been the apparent failure of the scientific and technical community to convince decision makers (both official and private) that the sound implementation of seismic microzonation projects are a valid instrument to mitigate the negative effects that earthquakes have on the population, on the physical infrastructure and on the environment. An attempt will be made in this paper to analyze these "non technical" aspects and try to arrive at some conclusions as well as to some possible lines of action for the successful implementation of seismic microzonation projects in the seismic risk prone Latin American and Caribbean nations.

    2013-03-01

    From the technical point of view different groups must be distinguished in the provision of orthopedic shoes for athletes. The one group encompasses athletes who are provided with insoles in the hope of improved comfort or better performance. The other group includes athletes with diseases or injuries of the lower limbs for whom the provision of appropriate shoes and insoles makes it possible for them to participate again actively in their chosen sport. In such cases one has to differentiate between the purely physical disorder of the foot and biomechanical disorders. For the first group the correct fitting of the shoe is the most important factor whereas in the second group attempts are made to correct and/or compensate for the deficit by means of insoles and wedges as well as supporting or bedding elements. The particular challenge for all such measures is to achieve an as small as possible impairment on the sport activity or, in the ideal cases, even to support it. © Georg Thieme Verlag KG Stuttgart · New York.

    1997-01-01

    Beside the technical problems of ADTT which remain to be solved it is crucial for the ADTT progress that safety and economical aspects are considered already during the research and planning phases. Safety here stands for the converse of risk, negative consequences for human life and health and the environment together with the corresponding probabilities. The system to be considered includes all phases of an ADTT plant, a life cycle analysis (LCA). The risk analysis is useful for two purposes: comparison with other ways of handling nuclear waste, e.g. geological repository and for valuation of different construction designs. Due to lack of precise plans and adequate data the analysis will be more of a qualitative than quantitative type. The main risks appear in connection with repair and replacement work. 2 refs., 1 fig

    Understanding degradation phenomena and managing the detrimental effects of aging are important aspects of commercial nuclear power plant operations. Potential for materials degradation should be considered early in the design and development stages; during manufacturing, construction, and installation; and during all aspects of plant operation and maintenance. This would lead to increased reliability during plant operations, and would reduce the need for mitigating actions and unplanned maintenance. Thus, it is necessary to instill a culture at the technical, administrative, and management levels that continually asks, 'What happens with time?' The answer to this question is central to the continuous safe and economical operation of nuclear power plants. Based on the past 25 years of aging-related research at the U.S. Nuclear Regulatory Commission (NRC), the authors present an overview of the key elements of understanding and managing aging, and how they should be integrated for safe and economical power plant operation. The focus of this paper is hardware-oriented engineering and aging of materials. The paper discusses previous and ongoing NRC research studies on non-destructive examination and materials degradation that can be applied for proactive management of materials degradation and aging during plant operations.

    Full Text Available Solar energy has an increasing role in the global energy mix. The need for flexible storage photovoltaic systems and energy storage in electricity networks is becoming increasingly important as more generating capacity uses solar and wind energy. This paper is a study on the economic questions related to flexible storage photovoltaic systems of household size in 2018. The aim is to clarify whether it is possible in the European Union to achieve a payback of the costs of flexible storage photovoltaic system investments for residential customers considering the technology-specific storage aspects prevalent in 2018. We studied seven different flexible storage photovoltaic investments with different battery technologies in Germany, France, Italy, and Spain because, in Europe, these countries have a prominent role with regard to the spread of photovoltaic technology. These investment alternatives are studied with the help of economic indicators for the different cases of the selected countries. At the end of our paper we come to the conclusion that an investment of a flexible storage photovoltaic (PV system with Olivine-type-LiFePO4, Lithium-Ion, Vented lead-acid battery (OPzS, Sealed lead-acid battery (OPzV, and Aqueous Hybrid Ion (AHI batteries can have a positive net present value due to the high electricity prices in Germany and in Spain. The most cost-effective technology was the Olivine-type-LiFePO4 and the Lithium-Ion at the time of the study. We suggest the provision of governmental support and uniform European modifications to the regulatory framework, especially concerning grid fees and tariffs, which would be necessary in the beginning to help to introduce these flexible storage PV systems to the market.

  11. Expressiveness in musical performance: Pedagogic aspect

    Jović Natalija R.

    2016-01-01

    Full Text Available The subject of our research relates to pedagogic aspects of expressive vocal-instrumental musical performance. We intended to examine: (1 how undergraduate students see/conceptualize and evaluate expressiveness in musical performance; (2 whether and how they were trained in the skill of expressive musical performance during their musical training; (3 whether and in which way they rehearse the expressive component of musical performance and interpretation and (4 whether there are any differences regarding gender, age, instrument, department, year of study and years of instrument playing in relation to the group of dependant variables related to expressiveness, tuition and practice. The sample for the research included 82 students of instrumental and theory departments at the Faculty of Music in Belgrade. Psychological and pedagogical aspects of musical expressiveness during vocal-instrumental performance were analyzed. The results show that students highly evaluate expressiveness but its place is secondary compared to mastering technical and tonal requirements. Statistically significant differences were shown regarding gender, age and departments. It can be concluded that there is a potential for the development and enhancement of expressiveness of students if we abandon the traditional view that expressiveness is linked exclusively to talent. The findings indicate that pedagogical work should be directed towards finding purposeful strategies for training individual expressiveness.

    Workers in the sawmilling industry are at risk of various ocular hazards as a direct result of the sawmilling processes. The aim of this study was to determine the pattern of conjunctival disorders between technical and administrative sawmill workers in Benin, Nigeria. A cross-sectional study was performed on sawmill workers in Benin, Nigeria, between January and May 2009, with the aid of pre-tested questionnaires. Ocular examination was performed on all subjects. Data obtained were recorded and analysed using SPSS version 13. A total of 553 sawmill workers were studied, among whom 449 (81.2%) and 104 (18.8%) were technical and administrative workers, respectively. There were 496 (89.7%) males and 57 (10.3%) females. The age range was 15-80 years, with a mean of 38.9 years (SD 12.8). Pingueculum was found in 127 (23%) workers, among whom 122 (27.2%) were technical workers and 5 (4.8%) were administrative workers. Pterygium was present in 65 (11.8%) workers, among whom 64 (14.3%) were technical workers and 1 (1%) was an administrative worker. Seven (1.6%) technical workers used protective eyewear; 2 (0.4%) wore this protective eyewear regularly. Technical sawmill workers are at risk of developing conjunctival disorders, which result from chronic ocular irritation. This can be prevented by the provision of protective eye devices in the workplace.

  16. Some global aspects regarding nuclear spent fuel management

    2002-01-01

    The globalization means the worldwide extension of certain aspects of social or economic processes, structural or environmental changes, or concerning working methodologies, technical activity, industrial production, etc. At present the emergence of global aspects is more frequently observed, being determined by the rapid development of computerized systems and of transfer of information, by the development of big transnational companies and due to the increasing international co-operation. Some of the manifested global aspects could be beneficial for the development of the human society, other could be not. It is necessary to perform an adequate analysis from this view point and to promote appropriate measures to enhance the positive global aspects and to mitigate the negative global aspects. These measures can have a good efficiency only if they are pursued at global level, but for this it is necessary to build an adequate international coordinating body, having the corresponding instruments for action. The global aspects identified in the field of nuclear power may be divided into two categories, namely: - related to the main features of nuclear power; - regarding the specific features of some subdivisions of the field, as for example, spent fuel management. In the paper both categories are discussed. The influence of the global aspects on the development of nuclear power and particularly on the back end activities of the fuel cycle, is also presented. At the same time, some possible actions for enhancing nuclear power development are proposed

    Kikta, Edward J

    2011-01-01

    A GC method for the analysis of technical and formulated bifenthrin samples was evaluated in a collaborative study. Bifenthrin is determined by using a 50% (trifluoropropyl)-methylpolysiloxane wide-bore capillary column and flame ionization detector. Ten samples, consisting of four formulations and a technical material were analyzed by 12 collaborators using Youden pairs. The four formulation types included in this study were microemulsion (ME), wettable powder (WP), suspension concentrate (SC), and emulsifiable concentrate (EC). Variability in the analysis of two of the formulation types, SC and EC, was later found to be due to the noncommercial containers used to hold the test samples. Because of this, valid data could not be obtained for the EC and SC. For the two formulations for which valid data could be obtained, ME and WP, and the technical chemical, accuracy and variability results are typical of large data sets. For the technical chemical and the two formulations for which valid data were obtained, Official First Action is recommended.

    The use of modulated toroidal coils offers a new path to the tokamak-stellarator hybrids. Low-aspect-ratio configurations can be found with robust vacuum flux surfaces and rotational transform close to the transform of a reverse-shear tokamak. These configurations have clear advantages in minimizing disruptions and their effect and in reducing tokamak current drive needs. They also allow the study of low-aspect-ratio effects on stellarator confinement in small devices

    Full Text Available Organizations adopt diverse strategies to govern the technical and managerial aspects of sustainability implementation processes. The need for better leading and managing people-related issues emerges as companies aim for more effective change towards sustainability. The human aspect of the sustainability implementation process is mostly not paid enough attention, but it can significantly affect the success of a change management program by creating hurdles or easing the process. This study considers three human-related factors: resistance to change, internal communication, and employee engagement in sustainability activities of organizations. The aim of the study is to explore how these human factors are managed by tourism companies for organizational sustainability. For this purpose four companies from different sectors of tourism are chosen as case studies and the results are examined using qualitative data analysis techniques. The results indicate that the companies which are in a more advanced stage of sustainability implementation manage human factors using a greater number of channels and employ varied strategies. The results can provide insights into how organizations tackle the challenges of managing human aspect and display the practices that contribute to successful change management programs for achieving organizational sustainability through people.

    Full Text Available Vietnam plays important role in Russian policy in the Asia-Pacific region. Military-technical cooperation holds special position in Russian-Vietnamese relations. The aim of the article is the detection of the special features of military-technical cooperation between Russia and Vietnam, and also challenges and opportunities it provides for Russian policy. After the collapse of the USSR defense interaction between Russia and Vietnam was determined by commercial foundations. Vietnam needed new Russian weapons to protect its interests, first of all, in the South China Sea. For Moscow military-technical cooperation with Vietnam got economic significance. But later there was a rise of political dimension of cooperation in this sphere, influenced by some external factors. The period of the 2000-2010s was marked by growth of arms sales from Russia to Vietnam. It was mostly caused by the escalation of the South China Sea conflict, for which US-Chinese contradictions began to play an increasing role. Military-technical coopera-tion with Vietnam influenced some aspects of policy of Russia in the region. There was an increase of indi-rect involvement of Russia into the South China Sea conflict. Russian arms sales for Vietnam became one of problems in Russian-Chinese relations. But Russia and China could cope with these disputes, partly because of enlargement of their interaction in international relations, including the demonstration of similar position for some aspects of the South China Sea conflict. In the framework of development of defense cooperation with Vietnam, Russia could get special conditions of access to facilities of Cam Ranh Bay that strengthened its strategic positions in the region. Russian cooperation with Hanoi in military-technical field and general reinforcement of Russian positions in Vietnam might be also a reason for contradictions with the US.

    2017-06-01

    Custom tailors working in the informal sector in Nairobi, Kenya, mainly acquire technical skills through undertaking traditional apprenticeships (TAs). However, most of these tailors are semi-skilled, produce low-quality products and are often poorer than their formally trained counterparts. This qualitative case study explores the aspects of technical skills and knowledge which tailoring apprentices develop, and the factors which influence these outcomes. The findings show that apprentices do acquire basic technical skills for immediate application to ongoing tailoring activities (such as how to take body measurements, draft patterns, and cut, sew and finish constructed garments). However, apprentices do not acquire the technical knowledge that underpins the trade. Most master tailors who have completed TAs lack technical knowledge and have no access to technical skills upgrading. This perpetuates the cycle of basic and limited technical skills transfer to apprentices, poor performance and poverty among tailors. Both apprentices and master tailors expressed concern over knowledge limitations in TAs and a need to access further training to improve skills and acquire knowledge of the trade. The authors of this article argue that, technically and pedagogically, skilled master tailors are critical to improving training quality. Complementary training in theoretical knowledge is also important in improving apprentices' technical skills and understanding of the trade. Inclusion of TAs in government policy may help ensure sustainable improvement of skills.

    One comprehensive part of nursing practice is performing technical skills and handling of medical equipment. This might be challenging for new registered nurses (RNs) to do in patient-safe way. The aim of this study was to describe and compare the extent to which new RNs perform various technical skills and handle medical devices in different settings, and to investigate their possibility for continued learning in this respect. A further aim was to describe their perceptions of incident reporting related to technical skills and medical devices. A cross-sectional study with descriptive and comparative design. RNs who recently graduated from a nursing programme at three Swedish universities and had worked as a RN for up to 1 year were included in the study (n=113, response rate 57%). Data were collected by means of a postal questionnaire. Half of the RNs reported that they performed several of the listed tasks every day or every week, regardless of workplace. These tasks were most frequently performed in surgical departments. The majority of the participants (76%) stated a need of continued practical training. However, less than half of them (48%) had access to a training environment. Several participants (43%) had been involved in incidents related to technical skills or medical devices, which were not always reported. Nearly a third of the participants (31%) did not use the existing guidelines when performing technical skills, and reflection on performance was uncommon. This study highlights the importance of shared responsibilities between nurse educators and health care employers to provide learning opportunities for new RNs in technical skills, to maintain patient safety. To increase the safety culture where nursing students and new RNs understand the importance of using evidence-based guidelines and taking a reflective approach in the performance of technical tasks is needed.

    2001-01-01

    ISAGEN designed and applied a multi-aspect methodology to classify and compare projects of the company's electricity generation options portfolio. It was developed from a holistic vision, integrating multidisciplinary information from the economic, environmental and technical aspects. This helped to classify the alternatives based on the sum of the values obtained for the different considered aspects. This document presents, in general form, the procedure adopted for the index formulation and selection of factors including the variables corresponding to the sub-aspects (or environmental dimensions) physical, biotic and social. The investigation's work, selection and classification of the variables were developed by an interdisciplinary group of experimented professionals in the environmental evaluation of projects. The integration of the three sub-aspects (physical, biotic and social) resulted in a hierarchy of projects based on environmental considerations, which were finally articulated with the respective values obtained from the technical and economical aspects. In general, the results obtained in each sub-aspect agreed with the hierarchy of projects based on an expert concept previous to the method application. In synthesis, it was observed that this technique is of great utility to make comparisons and general classifications because it allows to take advantage of information with different characteristics and include assumptions or artificial modifiable methodological items that reflect the structure of the deciding agents preferences at any given time

    1991-01-01

    The series of lectures which forms the basis of this book and took place in the winter of 1989/90 at the ETH in Zuerich were held for the purpose of discussing the stage of development of our system of ethics in view of the extremely fast pace of technological progress and the risks which accompany it. Legal, psychological and political aspects of the problem were examined, but the emphasis was placed on ethical aspects. The effects which are examined in conventional risk analyses can be considered as a part of the ethical and social aspects involved, and in turn, the consideration of ethical and social aspects can be viewed as an extension of the conventional form of risk analysis. In any case, among risk experts, the significance of ethical and social factors is uncontested, especially as regards activities which can have far-reaching repurcussions. Some objective difficulties interfere with this goal, however: - No generally acknowledged set of ethical values exists. - Cultural influences and personal motives can interfere. - Normally a risk assessment is carried out in reference to individual facilities and within a small, clearly defined framework. Under certain circumstances, generalizations which are made for complete technological systems can lead to completely different conclusions. One contribution deals with integral views of the risks of atomic energy from an ethical and social perspective. (orig.).

    Recently the psychological effects of space flight have gained in attention. In uncovering the psychological challenges that individuals and teams can face, we need research options that integrate psychosocial aspects with behavioral, performance, technical and environmental issues. Future perspectives in Space Psychology and Human Spaceflight are reviewed in this paper. The topics covered include psychosocial and neurobehavioural aspects, neurocognitive testing tools, decision making, autonomy and delayed communications, well being, mental health, situational awareness, and methodology. Authors were members of a European Space Agency (ESA) Research Topical Team on Psychosocial and Behavioral Aspects of Human Spaceflight. They discuss the different topics under a common perspective of a theoretical and practical framework, showing interactions, relationships and possible solutions for the different aspects and variables in play. Recommendations for every topic are offered and summarized for future research in the field. The different proposed research ideas can be accomplished using analogs and simulation experiments, short- and long-duration bed rest, and in-flight microgravity studies. These topics are especially important for future Moon and Mars mission design and training.

    Full Text Available In the world of investing and trading, in order to have a definite advantage and constantly create profit, you need to have a strategic approach. Generally speaking, the two main schools of thought and strategies in financial markets are fundamental and technical analysis. Fundamental and technical analysis differ in several aspects, such as the way of functioning and execution, the time horizon used, the tools used and their objective. These differences lead to certain advantages and disadvantages of each of the analyses. Fundamental and technical analysis are also a subject of critical reviews by the academic and scientific community and many of these reviews concern the methods of their application, i.e. the possibility of combining the two analyses and using them complementarily to fully utilize their strengths and advantages.

    Full Text Available In this study, the effect of the aspect ratio on the aerodynamics characteristic of flexible membrane wings with different aspect ratios (AR = 1 and AR = 3 is experimentally investigated at Reynolds number of 25000. Time accurate measurements of membrane deformation using Digital Image Correlation system (DIC is carried out while normal forces of the wing will be measured by helping a load-cell system and flow on the wing was visualized by means of smoke wire technic. The characteristics of high aspect ratio wings are shown to be affected by leading edge separation bubbles at low Reynolds number. It is concluded that the camber of membrane wing excites the separated shear layer and this situation increases the lift coefficient relatively more as compared to rigid wings. In membrane wings with low aspect ratio, unsteadiness included tip vortices and vortex shedding, and the combination of tip vortices and vortex shedding causes complex unsteady deformations of these membrane wings. The characteristic of high aspect ratio wings was shown to be affected by leading edge separation bubbles at low Reynolds numbers whereas the deformations of flexible wing with low aspect ratio affected by tip vortices and leading edge separation bubbles.

    1984-01-01

    The period from projecting and construction to operation and decommissioning of a nuclear power plant spans approximately 5a years. During this period it is necessary to resolve a range of technical, economic and social research problems. Even more complicated is the nuclear power complex as a whole. The respective technical and economic aspects are interactive and cannot be solved separately. It is therefore suggested that the respective national research and development program be linked with the national program of economic research, this both at the preparatory stage, in the course of work and during the evaluation of achieved results.

    Minimally invasive surgery for liver resections has a defined role and represents an accepted alternative to open techniques for selected cases. Robotic technology can overcome some of the disadvantages of the laparoscopic technique, mainly in the most complex cases. Precise dissection and microsuturing is possible, even in narrow operative fields, allowing for a better dissection of the hepatic hilum, fine lymphadenectomy, and biliary reconstruction even with small bile ducts and easier bleeding control. This technique has the potential to allow for a greater number of major resections and difficult segmentectomies to be performed in a minimally invasive fashion. The implementation of near-infrared fluorescence with indocyanine green (ICG) also allows for a more accurate recognition of vascular and biliary anatomy. The perspectives of this kind of virtually implemented imaging are very promising and may be reflected in better outcomes. The overall data present in current literature suggests that robotic liver resections are at least comparable to both open and laparoscopic surgery in terms of perioperative and postoperative outcomes. This article provides technical details of robotic liver resections and a review of the current literature. PMID:27500143

    This article examines the processes of technical mediation within familial care networks based on a study of home telecare targeted at older people. Supported by contributions from the actor-network theory as part of the social psychology of science and technology, these processes of technical mediation are analyzed using a qualitative approach. The data were gathered through six focus groups and four in-depth interviews; the participants in the study included users, relatives and formal carers. Thematic analysis techniques encompassing the information were used, revealing the effects on the patterns of caring relationships. The results show the interplay between presence-absence made possible by the devices; the two-way direction of care between the older people and the artifacts; and the process of sustaining care using the technology. We conclude that care should be seen as a socio-technical network where technology plays an active role in sustaining family relationships.

    Radiobiological data indicate that fast neutrons could bring a benefit in the treatment of some tumour types, and suggest mechanisms through which this benefit could be achieved. However, radiobiology also clearly indicates that there is a need for patient selection as well as for a high-physical selectivity. The main difficulty when interpreting the results of neutron therapy are the poor technical conditions in which the first treatments were applied. This explains why the value and the place of neutron therapy are not universally recognized, although more than 15000 patients have been treated so far worldwide. There are, however, clinical indications of fast neutrons bringing a benefit for the following tumour sites: salivary glands, paranasal sinuses, soft tissue sarcomas, prostatic adenocarcinomas, palliative treatment of melanoma and rectum. These tumours represent about 10-15% of all patients currently referred to the radiation therapy departments. (orig.)

    To identify and describe the factors that impact on the performance of scrub nurses' non-technical skills performance during the intra-operative phase of surgery. Non-technical skills have been identified as important precursors to errors in the operating room. However, few studies have investigated factors influencing non-technical skills of scrub nurses. Prospective observational study. Structured observations were performed on a sample of 182 surgical procedures across eight specialities by two trained observers from August 2012-April 2013 at two hospital sites. Participants were purposively selected scrub nurses. Bivariate correlations and a multiple linear regression model were used to identify associations among length of surgery, patients' acuity using the American Society of Anesthesiologists classification system, team familiarity, number of occasions scout nurses leave the operating room, change of scout nurse and the outcome, the non-technical skills performance of scrub nurses. Patient acuity and team familiarity were the strongest predictors of scrub nurses' non-technical skills performance at hospital site A. There were no correlations between the predictors and the performance of scrub nurses at hospital site B. A dedicated surgical team and patient acuity potentially influence the performance of scrub nurses' non-technical skills. Familiarity with team members foster advanced planning, thus minimizing distractions and interruptions that impact on scrub nurses' performance. Development of interventions aimed at improving non-technical skills has the potential to make a substantial difference and enhance patient care. © 2015 John Wiley & Sons Ltd.

    2002-01-01

    A regional Technical Cooperation project for Central and Eastern European countries was established and funded by the IAEA as a response to the region's need. Majority of these countries are now in the process of establishing/strengthening their infrastructure for assessment of structural integrity of primary circuit components for an appropriate level of safety and reliability. Moreover, extension of the operational life of the WWER nuclear power plants (NPPs) became part of the generation strategy in most of these countries. The overall objective of the project is to improve long term integrity of primary circuit components as a fundamental technical prerequisite to ensure plant operation until and beyond the design lifetime. In a series of workshops and technical meetings issues relevant to primary circuit component structural integrity with special regard to operational life optimization have been being addressed. The works under the project are coordinated with the European Commission's integrity related assistance projects, and some of the activities are jointly organized with the WANO Moscow Center. Main conclusions of the central topics are summarized in this paper

  10. Technical features to enhance proliferation resistance of nuclear energy systems

    International Nuclear Information System (INIS)

    2010-01-01

    It is generally accepted that proliferation resistance is an essential issue for the continued development and sustainability of nuclear energy. Several comprehensive assessment activities on the proliferation resistance of the nuclear fuel cycle have previously been completed, notably the International Nuclear Fuel Cycle Evaluation (INFCE) carried out under the auspices of the IAEA, and the Non-proliferation Alternative Systems Assessment Program (NASAP) review carried out by the USA. There have been, however, relatively few comprehensive treatments of the issue following these efforts in the 1970s. However, interest in and concern about this issue have increased recently, particularly because of greater interest in innovative nuclear fuel cycles and systems. In 2000, the IAEA initiated the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) and the US Department of Energy initiated the Generation IV International Forum (GIF). These projects are aimed at the selection and development of concepts of innovative nuclear energy systems and fuel cycles. Proliferation resistance is one of the fundamental considerations for both projects. In this context, the IAEA in 2001 initiated a study entitled 'Technical Aspects of Increasing Proliferation Resistance of the Nuclear Fuel Cycle'. This task is not intended as an effort to assess the merits of a particular fuel cycle system for the future, but to describe a qualitative framework for an examination of the proliferation resistance provided by the intrinsic features of an innovative nuclear energy system and fuel cycle. This task also seeks to provide a high level survey of a variety of innovative nuclear energy systems and fuel cycles with respect to that framework. The concept of proliferation resistance is considered in terms of intrinsic features and extrinsic measures. The intrinsic features, sometimes referred to as the physical/technical aspects, are those features that result from the

    Full Text Available Abstract In pursuit of promoting the artistic aspects, the current Rhythmic Gymnastics Code of Points (RGCP has been submeted significant changes that motivated this research, documentary and historical in character, which aimed to analyze the last eight Olympic cycles of RGCP. The research method used in this study is documentary and characterized by the information found in documents (RGCP that had not received any scientific treatment. From the analysis of different RGCP cycles, we found artistic aspects, and their connection with RG technical requirements. We observed that the RG has distinct stages (technical aspects, flexibility etc. While retaining its artistic roots (from Dance and Rhythm, in pursuit of sportivization and systematization of the sport, the first stage was characterized by a search for the sportivization and standardization of the modality based on the inclusion of new body elements in the RGCP . The second stage confirms our previous hypothesis, that in the last RGCP the artistic component had undergone few changes. We noticed, in an overview, that at the present time the current RGCP brings back the relationship between RG and its origins, influenced by Aesthetic Gymnastics (Swedish, Rhythmic and Dance. Condition observed once the current Code of Points (2013-2016 marks the story of sports, by two aspects: the permissiveness of routines with singing wich has not allowed since since the creation the RGCP and significant changes to the appreciation of the routines’ artistic aspects.

    Dry battery on a motorcycle has a rapid rate of voltage drop, life time is not too long, and a long charging time. These are problems for users of dry battery for motorcycle. When the rate in the voltage decreases, the energy storage in the battery is reduced, then at the age of one to two years of battery will be dead and cannot be used, it makes the user should replace the battery. New technology development of a motorcycle battery is lithium ion battery. Lithium ion battery has a specification that has been tested and possible to replace dry battery. Characteristics of lithium ion battery can answer the question on the dry battery service life, the rate of decrease in voltage and charging time. This paper discusses about the technical feasibility for commercialization of lithium ion battery for motorcycle battery. Our proposed methodology of technical feasibility by using a goldsmith commercialization model of the technical feasibility and reconfirm the technical standard using the national standard of motorcycle battery. The battery has been through all the stages of the technical feasibility of the goldsmith model. Based on the results of the study, lithium ion batteries have the minimum technical requirements to be commercialized and has been confirmed in accordance with the standard motorcycle battery. This paper results that the lithium ion battery is visible to commercialized by the technical aspect.

    Although simulation training is increasingly used to meet modern technology and patient safety demands, its successful integration within surgical curricula is still rare. The Dutch Urological Practical Skills (D-UPS) curriculum provides modular simulation-based training of technical and non-technical basic urological skills in the local hospital setting. This study aims to assess the educational impact of implementing the D-UPS curriculum in the Netherlands and to provide focus points for improvement of the D-UPS curriculum according to the participants. Educational impact was assessed by means of qualitative individual module-specific feedback and a quantitative cross-sectional survey among residents and supervisors. Twenty out of 26 Dutch teaching hospitals participated. The survey focussed on practical aspects, the D-UPS curriculum in general, and the impact of the D-UPS curriculum on the development of technical and non-technical skills. A considerable survey response of 95 % for residents and 76 % for supervisors was obtained. Modules were attended by junior and senior residents, supervised by a urologist, and peer teaching was used. Ninety percent of supervisors versus 67 % of residents judged the D-UPS curriculum as an important addition to current residency training (p = 0.007). Participants' aggregated general judgement of the modules showed a substantial percentage favorable score (M ± SE: 57 ± 4 %). The impact of training on, e.g., knowledge of materials/equipment and ability to anticipate on complications was high, especially for junior residents (77 ± 5 and 71 ± 7 %, respectively). Focus points for improvement of the D-UPS curriculum according to the participants include adaptation of the training level to residents' level of experience and focus on logistics. The simulation-based D-UPS curriculum has a high educational impact. Residents and supervisors consider the curriculum to be an important addition to current residency

    The events of the last years have put under the spotlight the politic and economic instability of the energy sources from crude oil. This has brought to the necessity to exploit alternative sources, such as bio fuels. It is possible to suppose for Italy, for a long time dependent from abroad energy supplying, that the development of biofuel industry will be an opportunity, also thanks to its background agriculture: it can rise, in fact, to an important role, thanks to biomass energy exploitation. In this paper will be made an analysis about the material and energy flows of the entire production chain of biodiesel obtained from sunflower, in order to evaluate its potential from technical, economic and environmental point of view

    1998-09-01

    It is widely acknowledged that the clinical aspects (diagnosis, decision, indication for treatment, follow-up) as well as the procedures related to the physical and technical aspects of patient treatment must be subjected to careful control and planning in order to ensure safe, high quality radiotherapy. Whilst it has long been recognized that the physical aspects of quality assurance in radiotherapy are vital to achieve and effective and safe treatment, it has been increasingly acknowledged only recently that a systematic approach is absolutely necessary to all steps within clinical and technical aspects of a radiotherapy programme as well. The need to establish general guidelines at the IAEA, taking into account clinical medical physics, radiation protection and safety considerations, for designing and implementing radiotherapy programmes in Member States has been identified through the Member States' increased interest in the efficient and safe application of radiation in health care. Several consultants and advisory group meetings were convened to prepare a report providing a basis for establishing a programme in radiotherapy. The present TECDOC is addressed to all professionals and administrators involved in the development, implementation and management of a radiotherapy programme in order to establish a common and consistent framework where all steps and procedures in radiotherapy are taken into account

Part 1 introduced the fundamental concept of unknown failures from an organizational, behavioral and cultural stand point. It also reported an industrial outlook to the problem, recent procedural standards, whilst discussing the financial implications and safety concerns. In this issue, the authors examine the technical aspects, reviewing the common causes of NFF failures in electronic, software and mechanical systems. This is followed by a survey on technological techniques actively being used to reduce the consequence of such instances. After discussing improvements in testability, the article identifies gaps in literature and points out the core areas that should be focused in the future. Special attention is paid to the recent trends on knowledge sharing and troubleshooting tools; with potential research on technical diagnosis being enumerated

    The Second Workshop on the Technical Aspects of Tsunami Warning Systems, Tsunami Analysis, Preparedness, Observation, and Instrumentation, sponsored and convened by the Intergovernmental Oceanographic Commission (IOC), was held on 1-2 August 1989, in the modern and attractive research town of Academgorodok, which is located 20 km south from downtown Novosibirsk, the capital of Siberia, USSR. The Program was arranged in eight major areas of interest covering the following: Opening and Introduction; Survey of Existing Tsunami Warning Centers - present status, results of work, plans for future development; Survey of some existing seismic data processing systems and future projects; Methods for fast evaluation of Tsunami potential and perspectives of their implementation; Tsunami data bases; Tsunami instrumentation and observations; Tsunami preparedness; and finally, a general discussion and adoption of recommendations. The Workshop presentations not only addressed the conceptual improvements that have been made, but focused on the inner workings of the Tsunami Warning System, as well, including computer applications, on-line processing and numerical modelling. Furthermore, presentations reported on progress has been made in the last few years on data telemetry, instrumentation and communications. Emphasis was placed on new concepts and their application into operational techniques that can result in improvements in data collection, rapid processing of the data, in analysis and prediction. A Summary Report on the Second International Tsunami Workshop, containing abstracted and annotated proceedings has been published as a separate report. The present Report is a Supplement to the Summary Report and contains the full text of the papers presented at this Workshop. Refs, figs and tabs

  11. Influence of non-technical policies on choices of waste solidification technologies

    International Nuclear Information System (INIS)

    Trubatch, S.L.

    1987-01-01

    This paper describes and discusses non-technical policy considerations which may improperly influence decisions on the solidification of low-level radioactive wastes (''LLW''). These policy considerations are contained principally in several State and Federal statutes which regulate various aspects of LLW disposal. One policy consideration in particular, the unqualified bias in favor of volume reduction, is shown to present a substantial potential for leading to technically suboptimal decisions on the appropriate processes for solidifying LLW. To avoid the unintended skewing of technical decisions by non-technical policy considerations, certain current policies may need to be revised to ensure that the choices of waste treatment, including decisions on solidification, are based primarily on reasonable assurance of adequate protection of public health and safety. This goal may be realized in part by basing any disposal fee structure on more than just LLW volume to include consideration of the waste's activity and its difficulty of confinement

    Glycosyl linkage (methylation) analysis is used widely for the structural determination of oligo- and poly-saccharides. The procedure involves derivatisation of the individual component sugars of a polysaccharide to partially methylated alditol acetates which are analysed and quantified by gas chromatography-mass spectrometry. The linkage positions for each component sugar can be determined by correctly identifying the partially methylated alditol acetates. Although the methods are well established, there are many technical aspects to this procedure and both careful attention to detail and considerable experience are required to achieve a successful methylation analysis and to correctly interpret the data generated. The aim of this article is to provide the technical details and critical procedural steps necessary for a successful methylation analysis and to assist researchers (a) with interpreting data correctly and (b) in providing the comprehensive data required for reviewers to fully assess the work.

    2018-01-01

    Full Text Available To deal with the rising integration of stochastic renewables and energy intensive distributed energy resources (DER to the electricity network, alternatives to expensive network reinforcements are increasingly needed. An alternative solution often under consideration is integrating flexibility from the consumer side to system management. However, such a solution needs to be contemplated from different angles before it can be implemented in practice. To this end, this article considers a case study of the Amsterdam ArenA stadium and its surrounding network where flexibility is expected to be available to support the network in the future. The article studies the technical aspects of using this flexibility to determine to what extent, despite the different, orthogonal goals, the available flexibility can be used by various stakeholders in scenarios with a large load from electric vehicle charging points. Furthermore, a legal study is performed to determine the feasibility of the technical solutions proposed by analysing current European Union (EU and Dutch law and focusing on the current agreements existing between the parties involved. The article shows that flexibility in the network provided by Amsterdam ArenA is able to significantly increase the number of charging points the network can accommodate. Nonetheless, while several uses of flexibility are feasible under current law, the use of flexibility provided by electric vehicles specifically faces several legal challenges in current arrangements.

    To maintain and improve the efficiency and safety of operations in numerous industries, it is necessary to develop programs that enhance teamwork. This can be achieved through empirical investigations that identify influential factors contributing to teamwork. This study focused on technical skill proficiency and leadership as influential factors and examined the relationships among these factors and teamwork behaviors. A series of measurements was performed on 54 operations teams with the cooperation of the training center of thermal power plants. Teamwork behaviors in training under simulated abnormal conditions were evaluated through instructors' observation using a behavior checklist. Technical skill proficiency was measured by conducting a brief survey on instructors. Leadership was measured on the basis of followers' responses on questionnaire scales. Based on the scores of technical skill proficiency and leadership, hierarchical cluster analysis revealed three types of teams: (a) F-type - the technical skills of followers are superior to those of leaders; (b) LF-type - both leaders and followers are proficient in technical skills; and (c) L-type - the technical skills of leaders are superior to those of followers. ANOVAs were conducted to examine differences in teamwork behavior for the three types of teams. The main results revealed that LF-type teams actively engaged in information gathering and that leaders played a central role in these activities. In addition, the followers of F-type teams freely exchanged their ideas and opinions regarding problems and actively discussed how to solve them. These findings suggest that teamwork behaviors can vary depending on technical skill proficiency and leadership in teams. Future research is needed to identify additional factors affecting teamwork that are not measured in this study. (author)

    2010-01-01

    Approaches to technical and scientific support for the State NPP Program in Belarus are described and compared with the recommendations of the IAEA. The past infrastructure in Belarus did not have specialized technical support organization (TSO) for the nuclear regulatory body. Currently, there are two technical and scientific support centers, nominated by decrees. They are part of the NPP infrastructure and belong to the National Academy of Sciences and the Ministry of Energy. It is a challenge to establish the needed TSO capacities for the nuclear regulatory body (the Ministry for Emergency Situations) inside existing institutions of the Ministry for Emergency Situations (MES). Initially, the new technical support structure could focus on well known topics like emergency preparedness and radiation protection. The scope of work has to be extended to all major aspects of radiation and nuclear safety of the new NPP soon. National education as well as international knowledge transfer are important for that. Tasks and challenges of new technical safety institution(s) are described. (author)

    1975-01-01

    Some of the design and analysis aspects of the NAEG studies at safety-shot sites are reviewed in conjunction with discussions of possible new approaches. The use of double sampling to estimate inventories is suggested as a means of obtaining data for estimating the geographical distribution of plutonium using computer contouring programs. The lack of estimates of error for plutonium contours is noted and a regression approach discussed for obtaining such estimates. The kinds of new data that are now available for analysis from A site of Area 11 and the four Tonopah Test Range (TTR) sites are outlined, and the need for a closer look at methods for analyzing ratio-type data is pointed out. The necessity for thorough planning of environmental sampling programs is emphasized in order to obtain the maximum amount of information for fixed cost. Some general planning aspects of new studies at nuclear sites and experimental clean-up plots are discussed, as is the planning of interlaboratory comparisons. (U.S.)

    A management-planning model envisioned as a useful tool for planning and guiding the development of a nuclear waste repository data base is described. It incorporates the technical assessment goals and objectives of the US Nuclear Regulatory Commission, and it provides a strategy for reaching them. The model strategy includes provisions for the breadth, timeliness, and defensibility of its predictions. Consideration is given to observational data, its structure, and future refinements. The structure of the data is consistent with the needs of a systems model whose structure is proposed to resolve questions about repository safety. Uncertainties are categorized as an aid in defining and resolving technical issues. The model provides a framework for ultimately exposing all the sensitive and controversial factors. Some quantitative aspects of data acquisition are presented. 12 figures.

    1976-01-01

    A bid evaluation method is described which, it is claimed, facilitates a distinct and objective judgement of bids, taking into account the importance of the components, systems, and technical aspects evaluated with regard to the operation and safety of a nuclear power station. The evaluation basically consists of a cost assessment of the scope of supply deviations and a numerical evaluation of the technical design, the latter being a particularly novel feature of the method. The logic applied in both processes is shown. Main evaluation criteria which are applied for most components and systems are given as reliability, function and performance, safety, operation and maintenance, and materials. The judgements given to these evaluation criteria form the basis of the numerical bid evaluation described, which is carried out with the aid of computer programs. (U.K.)

    Full Text Available El presente trabajo tuvo como objetivo estudiar los factores que intervienen en la selección técnico económico de goteros. En el estudio fueron utilizados emisores autocompensados y no autocompensados, considerando a los aspectos técnicos como porcentaje de suelo humedecido, número de emisores por planta y coeficiente de uniformidad y precio y la presión de operación del emisor como aspectos económicos. Los resultados muestran que la presión de operación de los emisores es el factor más importante a considerar en la selección, ya que para valores más bajos de presión de operación se obtuvieron menores valores de costo total anualizado, independiente del tipo de gotero. En general, los goteros no autocompesados presentaron valores de costo anualizado menores, para un rango de presión similar. Finalmente el análisis tecnico-económico en la selección de emisores es un procedimiento importante.The objective of this research was to study the parameters that affect the technical-economical selection of emitters. In the study compensated and non-compensated emitters were used. The technical aspects considered were: percentage of wetted soil, number of emitters per plant and the uniformity coefficient as well as price and operation pressure for economic aspects. The results shows that the operation pressure of emitters is the most important factor to be considered in the selection , with smaller values of pressure giving lower total annual cost, independently of the type of emitter. In general, the non-compensated emitter shows lower annual cost values than for compensated emitters, for a similar range of pressures. Finally the technical-economical analysis in the emitter selection is an important procedure.

    The use of renewable energy for the continuously growing global population is becoming increasingly important. These forms of energy not only broaden the urgently needed resource base, but are also free from emission of CO{sub 2}, SO{sub 2}, NO{sub x} etc. The Federal German Government early recognized this and has provided more than DEM 4000 million for this purpose since 1973. Together with Japan and the USA, Germany belongs to the three leading nations in the world in R and D on the application of renewable energy. It has by far the largest and most broadly based programme in Europe. The technical and economical progress of wind power is very promising in Germany. It has scale demonstration programme `250 MW Wind`. Since 1991 another important impetus has been the sources (wind power presently 0.1728 DEM/kWh). In 1994, the rated wind power capacity was doubled to 643 MW. Electricity production in 1994 was around 1000 million kWh or 0.2 % of total German electricity production. The often discussed goal of producing one or more per cent of the German electricity by wind power seems to be attainable on a medium time scale by modern medium scale wind turbines or even large scale turbines. This is based on the promise that various nontechnical barriers will be overcome. (author)

    The safety of a nuclear facility depends not only on the fulfillment of all technical requirements, but also on the role of non-technical aspects. The primary causation of incidents or accidents in a nuclear facility is human error which is non-technical. Therefore, in order to enhance safety, efforts from the technical aspects are as important as efforts to deal with the human factor which can be done through the application of safety culture in the facility. Incidents that took place in the Experimental Fuel Element Installation (EFEI) of PTBN - BATAN from 2011 to 2012 were caused by aging instruments and human error. In order to prevent accidents and to enhance safety, non-technical efforts that were done in the EFEI were, interalia, the obligations on all personnel to attend the pre-lab briefing, to prepare a work proposal, to compose a HIRADC (hazard identification, risk assessment, and determining control) document, to utilize self protection devices, to perform a routine maintenance, and to practice safe behavior. All personnel were involved in all those efforts. Safety is the first priority and can always be improved in the facility. A strong commitment of and cooperation between the top management and the staff are needed. (author)

    At present, in Japan, there exists no law specifically regulating the underground disposal of radioactive wastes although various regulations deal with disposal safety measures in a general way. For the moment, apart from the need to gain public acceptance of such disposal, the problem is essentially one of technical feasibility, and a geological study is currently being undertaken by the Science and Technology Agency. This same Agency is also looking at the problem of a long-term waste management system, but it is the Nuclear Safety Commission, created in 1978, which will be primarily responsible for all regulatory aspects of safety.

    In the article, the problem of application of the pattern recognition (a relatively young area of engineering cybernetics) for analysis of complicated technical systems is examined. It is shown that the application of a statistical approach for hard distinguishable situations could be the most effective. The different recognition algorithms are based on Bayes approach, which estimates posteriori probabilities of a certain event and an assumed error. Application of the statistical approach to pattern recognition is possible for solving the problem of technical diagnosis complicated systems and particularly big powered marine diesel engines.

    Bakken, Bjoern Harald

    1997-12-31

    This thesis studies system operation and operational costs of primary and secondary control in hydro and thermal power systems. The cost of providing primary control reserves in thermal power systems is estimated to 1-3% of total production cost. Hydro power units, on the other hand, provide a very cheap primary reserve compared to thermal units. The HVDC (High Voltage Direct Current) connection can be used for primary control in either direction but the thesis only considers substitution of reserves in the thermal system with reserves from the hydro system. Since the HVDC connection is easy to control, the transient characteristics are considerably improved, and one can substitute an amount of thermal spinning reserve corresponding to the available HVDC capacity with little disturbance in any system. A more realistic alternative, at present, is to sell secondary control reserves across the HVDC connections. Keeping spinning reserve for automatic secondary control in a thermal power system is estimated to cost 3-5% of total production cost. Secondary control reserves probably cannot compete with the value of the peak load export, but one should seriously consider using part of the HVDC capacity as secondary control reserve for the thermal system during off-peak hours with. The author discusses the concept of automatic secondary control both theoretically and by simulations and finds that there are no special technical difficulties in introducing automatic secondary control in the Nordel (an organization for Nordic power cooperation) system. 78 refs., 4 figs., 23 tabs.

    The north-east black-out in the 1960s, the Arab oil embargo at the beginning of the 1970s and the nuclear accident at Three Mile Island in the 1970s have profoundly affected the electricity supply industry in the United States. This paper explains the effects of these events on the electricity supply industry from the socio-economic and political points of view. The development trends affecting the present structure of the supply industry are indicated in the context of environmental factors. The technical development of power plant equipment and -systems and also of alternative energy sources in the light of these factors are discussed. (orig.) [de

    Adverse events still occur despite ongoing efforts to reduce harm to patients. Contributory factors to adverse events are often due to limitations in clinicians' non-technical skills (e.g. communication, situation awareness), rather than deficiencies in technical competence. We developed a behavioural rating system to provide a structured means for teaching and assessing scrub practitioners' (i.e. nurse, technician, operating department practitioner) non-technical skills. Psychologists facilitated focus groups (n = 4) with experienced scrub practitioners (n = 16; 4 in each group) to develop a preliminary taxonomy. Focus groups reviewed lists of non-technical-skill-related behaviours that were extracted from an interview study. The focus groups labelled skill categories and elements and also provided examples of good and poor behaviours for those skills. An expert panel (n = 2 psychologists; n = 1 expert nurse) then used an iterative process to individually and collaboratively review and refine those data to produce a prototype skills taxonomy. A preliminary taxonomy containing eight non-technical skill categories with 28 underlying elements was produced. The expert panel reduced this to three categories (situation awareness, communication and teamwork, task management), each with three underlying elements. The system was called the Scrub Practitioners' List of Intraoperative Non-Technical Skills system. A scoring system and a user handbook were also developed. A prototype behavioural rating system for scrub practitioners' non-technical skills was developed, to aid in teaching and providing formative assessment. This important aspect of performance is not currently explicitly addressed in any educational route to qualify as a scrub practitioner. © 2012 Blackwell Publishing Ltd.

    Hansell, H.F.; Moyer, D.P.

    1986-01-01

    A BWR Owners' Group Technical Specification Improvement (TSI) Committee was formed in late 1983. A primary goal of this Committee was to encourage the development of a probabilistic methodology for technical specification improvements which could be readily applied by utilities. The TSI Committee elected to hire a Contractor to develop and demonstrate a method. After the Contractor was selected and has started work, the committee decided to establish a Technical Review Group (TRG) to efficiently and effectively review the Contractor's analyses. The TRG met frequently with the Contractor as the analyses were being performed. These meetings were held at the Contractor's facility in order to allow direct contact between reviewers and individuals performing the work. The TRG was also involved with all major interactions with the NRC. The significance and merit of using a peer review group in this manner is the theme of this paper. In order to present a discussion of the significance and merit of the TRG, the activities are described. The summary of the analytical approach is provided to more full understand the TRG activities

  7. ALWR utility requirements - A technical basis for updated emergency planning

    International Nuclear Information System (INIS)

    Leaver, David E.W.; DeVine, John C. Jr.; Santucci, Joseph

    2004-01-01

    U.S. utilities, with substantial support from international utilities, are developing a comprehensive set of design requirements in the form of a Utility Requirements Document (URD) as part of an industry wide effort to establish a technical foundation for the next generation of light water reactors. A key aspect of the URD is a set of severe accident-related design requirements which have been developed to provide a technical basis for updated emergency planning for the ALWR. The technical basis includes design criteria for containment performance and offsite dose during severe accident conditions. An ALWR emergency planning concept is being developed which reflects this severe accident capability. The main conclusion from this work is that the likelihood and consequences of a severe accident for an ALWR are fundamentally different from that assumed in the technical basis for existing emergency planning requirements, at least in the U.S. The current technical understanding of severe accident risk is greatly improved compared to that available when the existing U.S. emergency planning requirements were established nearly 15 years ago, and the emerging ALWR designs have superior core damage prevention and severe accident mitigation capability. Thus, it is reasonable and prudent to reflect this design capability in the emergency planning requirements for the ALWR. (author)

    Full Text Available In 1999 and 2000, the Masaryk Institute of Advanced studies of CTU in Prague launched a study of the efficiency of human resource management in Czech enterprises, with emphasis on technically educated managers. About 85 managers, each responsible for 5-250 employees assessed their own HRM activities and attitudes and those of their firm. The following aspects were analysed: evaluating individual management areas, assessing the general management standard of the given company, awareness of the company's personnel management policy, manager's own contribution to formulating the company's personnel management strategy, developing job descriptions, using professional methods of employee selection, promoting employees to the status of manager, periodic assessment of employees, training of staff responsible for assessment, employee remuneration and other motivation tools, etc. Results and data analysis are given in the paper. The managers of the Czech companies reviewed are still involved mainly in operating management, and devote limited time to the conceptual work needed in order to formulate an integral company policy in the area of personnel management. On the basis of this analysis, further training for managers with technical education will be designed and organised by the Masaryk Institute of Advanced Studies.

A draft medical system architecture was developed based on stakeholder needs, system goals, and system behaviors, as captured in an ExMC concept of operations document and a system model. This talk will discuss a high-level view of the medical system, as part of a larger crew health and performance system, both of which will support crew during Deep Space Transport missions. Other mission components, such as the flight system, ground system, caregiver, and patient, will be discussed as aspects of the context because the medical system will have important interactions with each. Additionally, important interactions with other aspects of the crew health and performance system are anticipated, such as health & wellness, mission task performance support, and environmental protection. This talk will highlight areas in which we are working with other disciplines to understand these interactions.

    The anatomy of the mesenteric system and the hepatic arterial bed has been demonstrated to have a high degree of variation. This is important when considering pre-surgical planning, catheterization, and trans-arterial hepatic therapies. Although anatomical variants have been well described, the characterization and understanding of regional hepatic perfusion in the context of radioembolization have not been studied with great depth. The purpose of this review is to provide a thorough discussion and detailed presentation of the angiographic and technical aspects of radioembolization. Normal vascular anatomy, commonly encountered variants, and factors involved in changes to regional perfusion in the presence of liver tumors are discussed. Furthermore, the principles described here apply to all liver-directed transarterial therapies

    Kallenbach-Herbert, Beate; Brohmann, Bettina

    2010-09-01

    The paper highlights that a comprehensive approach to safety affords the consideration of technology, organisation, personnel and social environment. In several safety relevant contexts of nuclear waste disposal these fields are closely interrelated. The approach for the consideration of socio-scientific aspects which is sketched in this paper supports the systematic treatment of safety relevant non-technical issues in the safety case or in safety assessments for a disposal project. Furthermore it may foster the dialogue among specialists from the technical, the natural- and the socio-scientific field on questions of disposal safety. In this way it may contribute to a better understanding among the affected scientific disciplines in nuclear waste disposal.

  14. Safety aspects of long-term dry interim storage of type-B spent fuel and HLW transport casks

    International Nuclear Information System (INIS)

    Wolff, D.; Probst, U.; Voelzke, H.; Droste, B.; Roedel, R.

    2004-01-01

    Based on the German decision to minimise transports of spent fuel casks between nuclear power plants, reprocessing plants and central storage facilities several on-site storage facilities have been licensed till the end of 2003. Because of the large amount of type-B transport casks which are going to be used for long-term interim storage the question of time limited type-B license maintenance during the storage period of up to 40 years has been discussed under different aspects. This paper describes present technical aspects of the discussion. A main aspect of transport cask qualification for interim storage is the long-term behaviour of the metallic seal lid system. Concerning this results from current experimental long-term tests with metallic ''Helicoflex''-seals in which pool water is enclosed are presented. The test series has been performed by the Federal Institute for Materials Research and Testing (BAM) on behalf of the Federal Office for Radiation Protection (BfS) since 2001. Finally, the paper presents a German concept for an authorities' and technical experts' exchange of experience, know-how and state of the art referring to cask dispatch in nuclear facilities. BAM has taken over a central role in this so-called ''co-ordinating institution for cask dispatching information'' (''KOBAF'') which contains an online data base and a technical working group meeting twice a year. The goal is to keep comparable technical standards for all nuclear sites and storage facilities which are going to load and dispatch casks of the same or similar types under the responsibility of different German state governments for the next decades

  15. Meteorological aspects of siting large wind turbines

    Energy Technology Data Exchange (ETDEWEB)

    Hiester, T.R.; Pennell, W.T.

    1981-01-01

    This report, which focuses on the meteorological aspects of siting large wind turbines (turbines with a rated output exceeding 100 kW), has four main goals. The first is to outline the elements of a siting strategy that will identify the most favorable wind energy sites in a region and that will provide sufficient wind data to make responsible economic evaluations of the site wind resource possible. The second is to critique and summarize siting techniques that were studied in the Department of Energy (DOE) Wind Energy Program. The third goal is to educate utility technical personnel, engineering consultants, and meteorological consultants (who may have not yet undertaken wind energy consulting) on meteorological phenomena relevant to wind turbine siting in order to enhance dialogues between these groups. The fourth goal is to minimize the chances of failure of early siting programs due to insufficient understanding of wind behavior.

  16. Aspects of studies on carbon cycle at ground surface

    International Nuclear Information System (INIS)

    Yamazawa, Hiromi; Kawai, Shintaro; Moriizumi, Jun; Iida, Takao

    2008-01-01

    Radiocarbon released from nuclear facilities into the atmosphere is readily involved in a ground surface carbon cycle, which has very large spatial and temporal variability. Most of the recent studies on the carbon cycle at the ground surface are concerned with global warming, to which the ground surface plays a crucial role as a sink and/or source of atmospheric carbon dioxide. In these studies, carbon isotopes are used as tracers to quantitatively evaluate behavior of carbon. From a view point of environmental safety of nuclear facilities, radiocarbon released from a facility should be traced in a specific spatial and temporal situation because carbon cycle is driven by biological activities which are spatially and temporally heterogeneous. With this background, this paper discusses aspects of carbon cycle studies by exemplifying an experimental study on carbon cycle in a forest and a numerical study on soil organic carbon formation. The first example is a typical global warming-related observational study in which radiocarbon is used as a tracer to illustrate how carbon behaves in diurnal to seasonal time scales. The second example is on behavior of bomb carbon incorporated in soil organic matter in a long-term period of decades. The discussion will cover conceptual modelling of carbon cycle from different aspects and importance of specifying time scales of interest. (author)

    2012-04-01

    Full Text Available The article sheds light on the origins of the military technical thinking in the military publishing of the Kingdom of Serbia with a view to marking a jubilee - the sixtieth anniversary of the Military Technical Courier. 'Vojin', the first military review, printed in the middle of 19th century as a private venture, covered a wide scope of military issues, among which a special place was given to 'the science of weapons'. No sooner had this review ceased to exist than The Headquarters of the Army of the Kingdom of Serbia started publishing a new military review, 'Ratnik', which, apart from the art of war and war literature, dealt with the science of weapons in order to inform officers about the latest achievements in military technology and to educate them as well. Serbian military thinking, including its technical aspect, did not fall behind modern trends in its European and world counterparts until 1914. The development of weaponry in Europe and the world was regularly covered on the pages of military reviews.

    Murray, R.L.; Walker, C.K.

    1989-01-01

    North Carolina will be the host state for a low-level radioactive waste (LLRW) disposal facility serving the Southeast Compact for 20 yr beginning in 1993. Primary responsibility for the project rests with the North Carolina Low-Level Radioactive Waste Management Authority, a citizen board. The North Carolina project embodies a unique combination of factors that places the authority in a position to exercise technical leadership in the LLRW disposal field. First, the Southeast Compact is the largest in the United States in terms of area, population, and waste generation. second, it is in a humid rather than an arid region. Third, the citizens of the state are intensely interested in preserving life style, environment, and attractiveness of the region to tourists and are especially sensitive to the presence of waste facilities of any kind. Finally, disposal rules set by the Radiation Protection Commission and enforced by the Radiation Protection Section are stricter than the U.S. Nuclear Regulatory Commission's 10CFR61. These four factors support the authority's belief that development of the facility cannot be based solely on engineering and economics, but that social factors, including perceptions of human risk, concerns for the environment, and opinions about the desirability of hosting a facility, should be integral to the project. This philosophy guides the project's many technical aspects, including site selection, site characterization, technology selection and facility design, performance assessment modeling, and waste reduction policies. Each aspect presents its own unique problems

  3. Features of an Error Correction Memory to Enhance Technical Texts Authoring in LELIE

    Patrick SAINT-DIZIER

    2015-12-01

    Full Text Available In this paper, we investigate the notion of error correction memory applied to technical texts. The main purpose is to introduce flexibility and context sensitivity in the detection and the correction of errors related to Constrained Natural Language (CNL principles. This is realized by enhancing error detection paired with relatively generic correction patterns and contextual correction recommendations. Patterns are induced from previous corrections made by technical writers for a given type of text. The impact of such an error correction memory is also investigated from the point of view of the technical writer's cognitive activity. The notion of error correction memory is developed within the framework of the LELIE project an experiment is carried out on the case of fuzzy lexical items and negation, which are both major problems in technical writing. Language processing and knowledge representation aspects are developed together with evaluation directions.

    The expansion of pulsed power applications research at Sandia National Labs requires increasing technician-level support from individuals trained in high voltage, short pulse technology. Large superpower generators need a broad-based training curriculum in all aspects of accelerator operation to satisfy recent Department of Energy (DOE) desires for formal certification of accelerator operators. This paper discusses the status of Sandia's safety and technical training program in pulsed power technology directed mainly towards high school graduate and technical school level students. Present safety training methodology requires that hazards for experimental facilities are identified first, a specific curriculum is then tailored to individuals' background experiences and hazards involved with their current assignments. In the technical training program, certification requirements are being established and a coursework program has been initiated in which subjects are organized into two sections. The first covers electrical principles and physical properties of pulsed power components. The second presents various support-type subsystems for accelerators

  6. Elastic modulus of muscle and tendon with shear wave ultrasound elastography: variations with different technical settings.

    Directory of Open Access Journals (Sweden)

    Brian Chin Wing Kot

    Full Text Available Standardization on Shear wave ultrasound elastography (SWUE technical settings will not only ensure that the results are accurate, but also detect any differences over time that may be attributed to true physiological changes. The present study evaluated the variations of elastic modulus of muscle and tendon using SWUE when different technical aspects were altered. The results of this study indicated that variations of elastic modulus of muscle and tendon were found when different transducer's pressure and region of interest (ROI's size were applied. No significant differences in elastic modulus of the rectus femoris muscle and patellar tendon were found with different acquisition times of the SWUE sonogram. The SWUE on the muscle and tendon should be performed with the lightest transducer's pressure, a shorter acquisition time for the SWUE sonogram, while measuring the mean elastic modulus regardless the ROI's size.

  15. Canada's nuclear achievement. Technical and economic perspectives

    International Nuclear Information System (INIS)

    Rummery, T.E.; Macpherson, J.A.

    1995-01-01

    Canada's leading role and eminent accomplishments in nuclear development now span more than half a century. They encompass aspects as diverse as the design and sale of nuclear power reactors and research reactor technology, to the establishment of a corps of scientists, engineers and technologists with the expertise to address a wide scope of important nuclear science issues. The success of a country of modest technical and financial resources, like Canada, in the highly technical and very competitive nuclear field is surprising to many Canadians, and does not fit the usual image we have of ourselves as 'drawers of water and hewers of wood'. For this reason alone, Canada's nuclear achievement makes an interesting and timely story. To address the many facets of Canada's nuclear activities over the past 50 years would obviously require space far beyond that available in this paper. We have therefore limited this review to highlights we judge to be the most pertinent and interesting from an historical, technical and economic perspective. We also indicate briefly our view of the future of nuclear power in the overall context of energy needs in a world that is becoming more industrial and increasingly environmentally conscious.

  16. Technical and organizational support for the operator

    International Nuclear Information System (INIS)

    Harrison, J.R.; Prescott, W.

    1981-01-01

    The requirement for staff and facilities on- and off-site to provide technical support to the plant personnel in normal and under accident conditions has been highlighted over the past 18 months as part of the post-TMI investigations. In the Central Electricity Generating Board (CEGB) considerable attention has always been paid to these requirements but naturally the experience of TMI has led to a review of the existing arrangements to determine whether any improvements and modifications were advisable. Similarly, the CEGB has always paid particular attention to the development of an appropriate emergency plant covering both the on-site damage control activities and off-site evacuation procedures consistent with the demography of the particular site being considered. An important aspect of gaining confidence in the potential success of the emergency plan is the regular practice and exercising of individual parts of the plan and its totality, and full attention is given also to these aspects. The paper reviews in some detail the ways in which the CEGB has met the requirements for the different aspects enumerated above, and will trace the approaches which have developed in the training and practices in respect of accident procedures.

    2013-10-01

    The learning and development of technical skills are paramount for neurosurgical trainees. External influences and a need for maximizing efficiency and proficiency have encouraged advancements in simulator-based learning models. To confirm the importance of establishing an educational curriculum for teaching minimally invasive techniques of pedicle screw placement using a computer-enhanced physical model of percutaneous pedicle screw placement with simultaneous didactic and technical components. A 2-hour educational curriculum was created to educate neurosurgical residents on anatomy, pathophysiology, and technical aspects associated with image-guided pedicle screw placement. Predidactic and postdidactic practical and written scores were analyzed and compared. Scores were calculated for each participant on the basis of the optimal pedicle screw starting point and trajectory for both fluoroscopy and computed tomographic navigation. Eight trainees participated in this module. Average mean scores on the written didactic test improved from 78% to 100%. The technical component scores for fluoroscopic guidance improved from 58.8 to 52.9. Technical score for computed tomography-navigated guidance also improved from 28.3 to 26.6. Didactic and technical quantitative scores with a simulator-based educational curriculum improved objectively measured resident performance. A minimally invasive spine simulation model and curriculum may serve a valuable function in the education of neurosurgical residents and outcomes for patients.

  1. Evaluation of decision making in technical support center for effective severe accident management

    International Nuclear Information System (INIS)

    Huh, C.; Suh, N.

    2010-01-01

    We have evaluated the technical and organizational aspect of the current SAMG focusing on the decision making process in TSC. Technically, we found that the current SAMG is a good software kind of tool which can help operators to manage the severe accident. But the clear cutting of EOP and SAMG, shift of plant control from MCR to TSC seems to have no firm ground to be accepted as it is. Study on the organizational behavior shows that the group decision under risky situation will be inevitably polarized either toward risky or cautious way. Since the current SAMG makes TSC to evaluate the pros and cons of strategies to be implemented and choose one based on group decision, we are not free of this group polarization phenomenon. We propose that the proven organization of EOP needs to be maintained and also that the SAMG needs to be more proceduralized. (authors)

  2. EO Model for Tacit Knowledge Externalization in Socio-Technical Enterprises

    Directory of Open Access Journals (Sweden)

    Shreyas Suresh Rao

    2017-03-01

    Full Text Available Aim/Purpose: A vital business activity within socio-technical enterprises is tacit knowledge externalization, which elicits and explicates tacit knowledge of enterprise employees as external knowledge. The aim of this paper is to integrate diverse aspects of externalization through the Enterprise Ontology model. Background: Across two decades, researchers have explored various aspects of tacit knowledge externalization. However, from the existing works, it is revealed that there is no uniform representation of the externalization process, which has resulted in divergent and contradictory interpretations across the literature. Methodology\t: The Enterprise Ontology model is constructed step-wise through the conceptual and measurement views. While the conceptual view encompasses three patterns that model the externalization process, the measurement view employs certainty-factor model to empirically measure the outcome of the externalization process. Contribution: The paper contributes towards knowledge management literature in two ways. The first contribution is the Enterprise Ontology model that integrates diverse aspects of externalization. The second contribution is a Web application that validates the model through a case study in banking. Findings: The findings show that the Enterprise Ontology model and the patterns are pragmatic in externalizing the tacit knowledge of experts in a problem-solving scenario within a banking enterprise. Recommendations for Practitioners\t: Consider the diverse aspects (what, where, when, why, and how during the tacit knowledge externalization process. Future Research:\tTo extend the Enterprise Ontology model to include externalization from partially automated enterprise systems.

    Bayer, A.; Heuser, F.W.

    1981-01-01

    This article presents an overview of the investigations and results of the German Risk Study (Phase A). Similar to its American counterpart [Reactor Safety Study (WASH-1400)], the German Risk Study assesses the societal risks associated with potential accidents in nuclear power plants sited in the Federal Republic of Germany. The technical part of the analysis was performed for a representative pressurized-water-reactor nuclear power plant of the 1300-MW(e) class. For the risk assessment, 19 sites were considered, with a total of 25 reactor units presently in operation, under construction, or undergoing the licensing procedure. In the spring of 1981 a translation of the main report [German Risk Study-Main Report (EPRI-NP-1804-SR)], including the investigations and results of Phase A, was published by the Electric Power Research Institute

  6. Safety aspects of long-term dry interim storage of Type B spent fuel and high-level transport casks

    Wolff, D.; Probst, U.; Voelzke, H.; Droste, B.; Roedel, R.

    2004-01-01

    Based on the German decision to minimise transport of spent fuel casks between nuclear power plants, reprocessing plants and central storage facilities several on-site storage facilities were licensed until the end of 2003. Because of the large amount of Type B(U) transport casks which are going to be used for long-term interim storage the question of time-limited Type B(U) licence maintenance during the storage period of up to 40 years has been discussed under different aspects. This paper describes present technical aspects of the discussion. A main aspect of qualification of transport casks for interim storage is the long-term behaviour of the metallic seal-lid system. Here we present results from current long-term experimental tests with metallic 'Helicoflex' seals in which pool water is enclosed. This series of tests has been performed by the Federal Institute for Materials Research and Testing (BAM) on behalf of the Federal Office for Radiation Protection (BfS) since 2001. Finally, the paper presents a German concept for an exchange of experience, know-how and state-of-the-art between authorities and technical experts with regard to cask dispatch in nuclear facilities. BAM has taken over a central role in this so-called 'coordinating institution for cask dispatching information' ('KOBAF') which entails management of an online database of cask-specific documents and a technical working group meeting twice a year. The goal is to keep comparable technical standards for all nuclear sites and storage facilities which are going to load and dispatch casks of the same or similar types under the responsibility of different German state governments for the coming decades.

    Wambersie, A.; Gahbauer, R.A.

    2002-01-01

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

  14. To Infinity and Beyond – Are Innovation Contests at Austrian Technical Colleges the Right Tool to Stimulate the Creative and Technical Potential of the Country?

    Directory of Open Access Journals (Sweden)

    Axel Zafoschnig

    2013-01-01

    Full Text Available Nowadays, creativity as it is applied for finding new technologies and making new inventions, is characterised by new unorthodox aspects of and approaches to problem solving. At the same time, innovation uses new scientific, technical and cultural elements to sustainably change the social structure of society. However, creative and innovative ideas are not affluent or ever-lasting resources. They need to be stimulated, elicited and put into realisation. This has to be done through expensive research and development cam-paigns, but may also be achieved at a lower level, namely, for example, at Austrian Technical Colleges. There, students are often encouraged to submit their diploma thesis projects in national and regional competitions and have recently proved to be very successful.

  15. Technical specifications for the successful fabrication of laminated seismic isolation bearings

    Energy Technology Data Exchange (ETDEWEB)

    Kulak, R F [Argonne National Laboratory, Argonne, IL (United States)

    1992-07-01

    High damping steel-laminated elastomeric seismic isolation bearings are becoming a preferred device for isolating large buildings and structures. In the United States, the current reference design for the Advanced Liquid Metal Reactor uses laminated bearings for seismic isolation. These bearings are constructed from alternating layers of rubber and steel plates. They are typically designed for shear strains between 50 to 100 percent and expected to sustain two to three times these levels for beyond design basis loading considerations. The technical specifications used to procure these bearings are an important factor in assuring thatthe bearings meet the performance requirements of the design. The key aspects of the current version of the Technical Specifications are discussed in this paper. (author)

  17. SOME ASPECTS OF TEACHING MEDIA LITERACY TO PRE-SCHOOL CHILDREN IN SLOVENIA FROM A PERCEPTION STANDPOINT OF TEACHERS AND PARENTS

    Directory of Open Access Journals (Sweden)

    Jurka Lepičnik Vodopivec

    2011-11-01

    Full Text Available This paper deals with media literacy as a multidimensional skill that parents and teachers possess. In this context we warn of the media-technical aspect of this skill and, within this aspect, of parents’ and teachers’ opinion on the presence of media in children’s lives. Following that, the paper explores teachers’ media-didactic competence as a component of educators’ media literacy. In the empiric part we used two aspects of fostering media literacy. One is the media-technical competence of parents and educators, while the other is the media-didactic competence of educators. We found that both parents and teachers believe that media have a strong presence in everyday lives of pre-school children and that they play an important role in teaching pre-school children. Teachers are aware of the importance of early teaching with media, for media and about media with the purpose of developing children’s media literacy, so they will not be afraid of media when they grow up.

  18. Curriculum Management Practices in Pedagogical Coordinations of Araucania Schools: Unveiling Technical/Instrumental Rationality, Control and Power Mechanisms Underlying

    Directory of Open Access Journals (Sweden)

    Juan Carlos Beltrán-Véliz

    2016-01-01

    Full Text Available This article consists of a case study regarding curriculum management practices of pedagogical coordinators in schools in Araucania area. The study aims to reveal technical/instrumental rationality, control and power mechanisms that underlie the curriculum management practices of such pedagogical coordinators of schools in Araucania region. A descriptive qualitative design based on the constructionist grounded theory and the constant comparative method is considered. Subjects studied included 12 technical leaders and 22 teachers from Araucania schools. Techniques for collecting information were semi-structured interview and texts for reading. Four categories rose from axial coding. Findings reveal that the teaching process is reduced to an instructional process. Furthermore, there is no uniformity of criteria regarding general functions that must be met. In the same extent, activity coordination is centered on bureaucratic administrative aspects, with main focus on task control. Regulations, programs and educational projects are used as control mechanisms. In addition, absence of spaces for professional discussion of pedagogical work and for constructive criticism is envisioned. This study concludes that pedagogical coordination practices are geared from an “instrumental rationality”, anchored in technical management set up in control and power.

    Research on effective integration of technical and non-technical skills in surgery team training is sparse. In a previous study we found that surgical teachers predominantly coached on technical and hardly on non-technical skills during the Definitive Surgical and Anesthetic Trauma Care (DSATC) integrated acute trauma surgery team training. This study aims to investigate whether the priming of teachers could increase the amount of non-technical skills coaching during such a training. Coaching activities of 12 surgical teachers were recorded on audio and video. Six teachers were primed on non-technical skills coaching prior to the training. Six others received no priming and served as controls. Blind observers reviewed the recordings of 2 training scenario's and scored whether the observed behaviors were directed on technical or non-technical skills. We compared the frequency of the non-technical skills coaching between the primed and the non-primed teachers and analyzed for differences according to the trainees' level of experience. Surgical teachers coached trainees during the highly realistic DSATC integrated acute trauma surgery team training. Trainees performed damage control surgery in operating teams on anesthetized porcine models during 6 training scenario's. Twelve experienced surgical teachers participated in this study. Coaching on non-technical skills was limited to about 5%. The primed teachers did not coach more often on non-technical skills than the non-primed teachers. We found no differences in the frequency of non-technical skills coaching based on the trainees' level of experience. Priming experienced surgical teachers does not increase the coaching on non-technical skills. The current DSATC acute trauma surgery team training seems too complex for integrating training on technical and non-technical skills. Patient care, Practice based learning and improvement.

    Full Text Available ABSTRACT This study estimates the technical efficiency of goat rearing in the province of Isparta in Turkey using Data Envelopment Analysis (DEA. The data used were collected from 92 goat farmers using the stratified sampling method by means of a questionnaire. The technical efficiency of the goat farming varied widely between 0.13 and 1.00. The mean efficiency of 92 goat farms was calculated to be 0.44 and 0.66 for constant and variable returns to scale assumptions, respectively. The greatest slacks were in feedstuff concentrates and labour used. The most significant factors affecting efficiency of goat production were farmer experience, cooperative membership, milk yield per goat, and family and hired labour. Technical efficiency should be improved by providing farmers with well-organised education, an extension program, and research and development programs on goat rearing.
