    1996-01-01

    Critical issues for the realization of commercial fusion reactor are discussed on the basis of a prediction of power source composition in the next century. The key issue is rather a relaxation in the construction site condition than a competitive cost in comparison with the nuclear fission power plant. It seems a logical conclusion that the competitor of the fusion plant in the cost will be a future CCT (Clean Coal Technology) and/or LNG plant loaded with a CO 2 recovery system. (author)

  5. Sociological and ethical issues in transplant commercialism.

    Science.gov (United States)

    Epstein, Miran

    2009-04-01

    'Global transplant commercialism' (practices and policies involving international trade in organs from living vendors, e.g., 'transplant tourism') is currently subjected to unprecedented criticism. In parallel, the debate around 'local transplant commercialism' (practices and policies that confine trade in organs from living vendors to national markets or economic unions) is heating up. In an attempt to assess the potential outcomes of these trends, this article reviews and discusses some sociological and ethical issues, ending with a proposal for a reinvigorated anticommercialist strategy. The current international campaign against global transplant commercialism is conducted by an ad hoc alliance between strange bedfellows, proponents of local transplant commercialism on the one hand and opponents of any transplant commercialism on the other. Disparities in the rigor of the respective ethical discourses, the expanding list of precedents of legitimized commerce in the human body, and the political economy of transplantation, all suggest that the former have the upper hand. Recent achievements in the struggle against international organ trafficking may not herald the abolition of transplant commercialism but rather presage its reconfiguration in deglobalized forms. In light of such a prospect, those who wish to prevent the pervasive commodification of the human body from entering the gates of transplant medicine should consider devising a new, perhaps more radical, strategy.

  9. NCAP projection displays: key issues for commercialization

    Science.gov (United States)

    Tomita, Akira; Jones, Philip J.

    1992-06-01

    Recently there has been much interest in a new polymer nematic dispersion technology, often called as NCAP, PDLC, PNLC, LCPC, etc., since projection displays using this technology have been shown to produce much brighter display images than projectors using conventional twisted nematic (TN) lightvalves. For commercializing projection displays based on this polymer nematic dispersion technology, the new materials must not only meet various electro- optic requirements, e.g., operational voltage, `off-state'' scattering angle, voltage holding ratio and hysteresis, but must also be stable over the lifetime of the product. This paper reports recent progress in the development of NCAP based projection displays and discusses some of the key commercialization issues.

  10. Tritium issues in commercial pressurized water reactors

    International Nuclear Information System (INIS)

    Jones, G.

    2008-01-01

    Tritium has become an important radionuclide in commercial Pressurized Water Reactors because of its mobility and tendency to concentrate in plant systems as tritiated water during the recycling of reactor coolant. Small quantities of tritium are released in routine regulated effluents as liquid water and as water vapor. Tritium has become a focus of attention at commercial nuclear power plants in recent years due to inadvertent, low-level, chronic releases arising from routine maintenance operations and from component failures. Tritium has been observed in groundwater in the vicinity of stations. The nuclear industry has undertaken strong proactive corrective measures to prevent recurrence, and continues to eliminate emission sources through its singular focus on public safety and environmental stewardship. This paper will discuss: production mechanisms for tritium, transport mechanisms from the reactor through plant, systems to the environment, examples of routine effluent releases, offsite doses, basic groundwater transport and geological issues, and recent nuclear industry environmental and legal ramifications.

    A survey of twenty-two recent conceptual fusion reactor designs was conducted to ascertain both generic and specific engineering data needs critical for the commercialization of magnetic confinement fusion (MCF). Design experts or advocates for each concept were queried as to the more critical engineering issues and data needs affecting the achievement of commercialization. For each concept, the technical issues were identified and the data needs quantified. Issues and data needs were then ranked based upon the experts' perceptions of the relative importance of each to the concept. The issues encompassed all aspects of the fusion reactor plant design including materials, performance, maintainability, operability, cost, safety and resources

    Science, new technology, patient care, dental reimbursement and government regulations all affect today's dental practitioners. To find out more about how such challenges may affect current private practitioners, the American Dental Association conducted the 2000 Membership Needs and Opinions Survey. A questionnaire was sent to 6,310 ADA members in January 2000 with follow-up mailings in February, March and April 2000. Data collection was completed in July 2000. The survey included questions on critical professional issues, and on perceptions of the ADA and ADA priorities. A total of 3,558 completed surveys were received for an adjusted response rate of 59.5 percent. Members rated the identified issues' level of importance to them. The top three issues included "maintaining my ability to recommend the treatment option I feel is most appropriate for my patients," "receiving fair reimbursement for the dental services I provide," and "protecting myself, my staff and my patients from communicable diseases." New dentists found other items to be more significant to them compared with members overall. Although ADA members as a whole had similar views on critical issues facing dentistry and ADA priorities, there were significant differences regarding some issues. New dentists were far more concerned about securing funds for their practice and paying off debt than were all ADA members. Minority dentists expressed greater levels of concern about certain issues than did all ADA members. When planning and implementing ADA activities, the Association should continue to take into account members' relative rankings of professional issues and note issues of special interest to selected membership subgroups.

    Goal Programming (GP) is perhaps the oldest and most widely used approach within the Multiple Criteria Decision Making (MCDM) paradigm. GP combines the logic of optimisation in mathematical programming with the decision maker's desire to satisfy several goals. The primary purpose of this book is to identify the critical issues in GP and to demonstrate different procedures capable of avoiding or mitigating the inherent pitfalls associated with these issues. The outcome of a search of the literature shows many instances where GP models produced misleading or even erroneous results simply because

    As oil reserves decline and the environment takes centre stage in public policy discussions, the merits and dangers of nuclear power and nuclear waste management continue to be debated. Canada is intent on building more reactors to increase energy production without destroying the planet, but it and other nuclear energy-producing countries face not only technical problems but also social and ethical issues. This book provides a critical antidote to the favourable position of government and industry. The contributors build their case by exploring key issues and developments. What do frequently used terms such as safety, risk, and acceptability really mean? How and why did the public consultation process in Canada fail to address ethical and social issues? What is the significance and potential of a public consultation process that involves diverse interests, epistemologies, and actors, including Aboriginal peoples? And how do we ensure that our frameworks for discussion are inclusive and ethical? This timely collection defuses the uncertainty, ambiguity, and ignorance that surrounds nuclear energy. It will appeal to academics, students, and stakeholders in public policy or environmental studies who want to think critically and more broadly about how we approach energy generation and waste management.

  20. Critical issues in NASA information systems

    Science.gov (United States)

    1987-01-01

    The National Aeronautics and Space Administration has developed a globally-distributed complex of earth resources data bases since LANDSAT 1 was launched in 1972. NASA envisages considerable growth in the number, extent, and complexity of such data bases, due to the improvements expected in its remote sensing data rates, and the increasingly multidisciplinary nature of its scientific investigations. Work already has begun on information systems to support multidisciplinary research activities based on data acquired by the space station complex and other space-based and terrestrial sources. In response to a request from NASA's former Associate Administrator for Space Science and Applications, the National Research Council convened a committee in June 1985 to identify the critical issues involving information systems support to space science and applications. The committee has suggested that OSSA address four major information systems issues; centralization of management functions, interoperability of user involvement in the planning and implementation of its programs, and technology.

  1. ITER - TVPS remote handling critical design issues

    International Nuclear Information System (INIS)

    1990-09-01

    This report describes critical design issues concerning remote maintenance of the ITER Torus Vacuum Pumping System (TVPS). The key issues under investigation are the regeneration/isolation valve seal and seal mechanism replacement; impact of inert gas operation; impact of remote handling (RH) on the building configuration and RH equipment requirements. Seal exchange concepts are developed and their impact on the valve design identified. Concerns regarding the design and operation of RH equipment in an inert gas atmosphere are also explored. The report compares preliminary RH equipment options, pumping equipment maintenance frequency and their impact on the building design, and makes recommendations where a conflict exists between pumping equipment and the building layout.

    Plasmas regimes with improved core energy confinement properties, i.e. with internal transport barriers (ITB), provide a possible route towards simultaneous high fusion performance and continuous tokamak reactor operation in a non-inductive current drive state. High core confinement regimes should be made compatible with a dominant fraction of the plasma current self-generated (pressure-driven) by the bootstrap effect while operating at high normalized pressure and moderate current. Furthermore, ITB regimes with 'non-stiff' plasma core pressure break the link observed in standard inductive operation between fusion performances and plasma pressure at the edge, thus offering a new degree of freedom in the tokamak operational space. Prospects and critical issues for using plasmas with enhanced thermal core insulation as a basis for steady tokamak reactor operation are reviewed in the light of the encouraging experimental and modelling results obtained recently (typically in the last two years). An extensive set of data from experiments carried out worldwide has been gathered on ITB regimes covering a wide range of parameters (q-profile, T{sub i}/T{sub e}, gradient length, shaping, normalized toroidal Larmor radius, collisionality, Mach number, etc). In the light of the progress made recently, the following critical physics issues relevant to the extrapolation of ITB regimes to next-step experiments, such as ITER, are addressed: 1. conditions for ITB formation and existence of a power threshold,; 2. ITB sustainment at T{sub i} {approx} T{sub e}, with low toroidal torque injection, low central particle fuelling but at high density and low impurity concentration,; 3. control of confinement for sustaining wide ITBs that encompass a large volume at high {beta}{sub N},; 4. real time profile control (q and pressure) with high bootstrap current and large fraction of alpha-heating and; 5. compatibility of core with edge transport barriers or with external core

  4. Critical Issues in Modelling Lymph Node Physiology

    Full Text Available In this study, we discuss critical issues in modelling the structure and function of lymph nodes (LNs, with emphasis on how LN physiology is related to its multi-scale structural organization. In addition to macroscopic domains such as B-cell follicles and the T cell zone, there are vascular networks which play a key role in the delivery of information to the inner parts of the LN, i.e., the conduit and blood microvascular networks. We propose object-oriented computational algorithms to model the 3D geometry of the fibroblastic reticular cell (FRC network and the microvasculature. Assuming that a conduit cylinder is densely packed with collagen fibers, the computational flow study predicted that the diffusion should be a dominating process in mass transport than convective flow. The geometry models are used to analyze the lymph flow properties through the conduit network in unperturbed- and damaged states of the LN. The analysis predicts that elimination of up to 60%–90% of edges is required to stop the lymph flux. This result suggests a high degree of functional robustness of the network.

  6. Professional medical organizations and commercial conflicts of interest: ethical issues.

    Science.gov (United States)

    Brody, Howard

    2010-01-01

    The American Academy of Family Physicians (AAFP) has recently been criticized for accepting a large corporate donation from Coca-Cola to fund patient education on obesity prevention. Conflicts of interest, whether individual or organizational, occur when one enters into arrangements that reasonably tempt one to put aside one's primary obligations in favor of secondary interests, such as financial self-interest. Accepting funds from commercial sources that seek to influence physician organizational behavior in a direction that could run counter to the public health represents one of those circumstances and so constitutes a conflict of interest. Most of the defenses offered by AAFP are rationalizations rather than ethical counterarguments. Medical organizations, as the public face of medicine and as formulator of codes of ethics for their physician members, have special obligations to adhere to high ethical standards.

  7. Radiation Safety Issues in High Altitude Commercial Aircraft

    Wilson, John W.; Cucinotta, Francis A.; Shinn, Judy L.

    1995-01-01

    The development of a global economy makes the outlook for high speed commercial intercontinental flight feasible, and the development of various configurations operating from 20 to 30 km have been proposed. In addition to the still unresolved issues relating to current commercial operations (12-16 km), the higher dose rates associated with the higher operating altitudes makes il imperative that the uncertainties in the atmospheric radiation environment and the associated health risks be re-examined. Atmospheric radiation associated with the galactic cosmic rays forms a background level which may, under some circumstances, exceed newly recommended allowable exposure limits proposed on the basis of recent evaluations of the A -bomb survivor data (due to increased risk coefficients). These larger risk coefficients, within the context of the methodology for estimating exposure limits, are resulting in exceedingly low estimated allowable exposure limits which may impact even present day flight operations and was the reason for the CEC workshop in Luxembourg (1990). At higher operating altitudes, solar particles events can produce exposures many orders of magnitude above background levels and pose significant health risks to the most sensitive individuals (such as during pregnancy). In this case the appropriate quality factors are undefined, and some evidence exists which indicates that the quality factor for stochastic effects is a substantial underestimate.

    The revolutionary and ubiquitous nature of nanotechnology has fetched it a considerable attention in the past few decades. Even though its enablement and application to various sectors including pharmaceutical drug development is increasing with the enormous government aided funding for nanotechnology-based products, however the parallel commercialization of these systems has not picked up a similar impetus. The technology however does address the unmet needs of pharmaceutical industry, including the reformulation of drugs to improve their solubility, bioavailability or toxicity profiles as observed from the wide array of high-quality research publications appearing in various scientific journals and magazines. Based on our decade-long experience in the field of nanotech-based drug delivery systems and extensive literature survey, we perceive that the major hiccups to the marketing of these nanotechnology products can be categorized as 1) inadequate regulatory framework; 2) lack of support and acceptance by the public, practicing physician, and industry; 3) developmental considerations like scalability, reproducibility, characterization, quality control, and suitable translation; 4) toxicological issues and safety profiles; 5) lack of available multidisciplinary platforms; and, 6) poor intellectual property protection. The present review dwells on these issues elaborating the trends followed by the industry, regulatory role of the USFDA and their implication, and the challenges set forth for a successful translation of these products from the lab and different clinical phases to the market.

  9. Capitals, assets, and resources: some critical issues.

    Science.gov (United States)

    Savage, Mike; Warde, Alan; Devine, Fiona

    2005-03-01

    This paper explores the potential of Bourdieu's approach to capital as a way of understanding class dynamics in contemporary capitalism. Recent rethinking of class analysis has sought to move beyond what Rosemary Crompton (1998) calls the 'employment aggregate approach', one which involves categorizing people into class groups according to whether they have certain attributes (e.g. occupations). Instead, recent contributions by Pierre Bourdieu, Erik Wright, Aage Sorensen, and Charles Tilly have concentrated on understanding the mechanisms that produce class inequalities. Concepts such as assets, capitals and resources (CARs) are often used to explain how class inequalities are produced, but there remain ambiguities and differences in how such terms are understood. This paper identifies problems faced both by game theoretical Marxism and by the rational choice approach of Goldthorpe in developing an adequate approach to CARs. It then turns to critically consider how elements of Bourdieu's approach, where his concept of capital is related to those of habitus and field, might overcome these weaknesses. Our rendering of his arguments leads us to conclude that our understanding of CARs might be enriched by considering how capital is distinctive not in terms of distinct relations of exploitation, but through its potential to accumulate and to be converted to other resources. This focus, we suggest, sidesteps otherwise intractable problems in CAR based approaches.

  10. Transportation access to Yucca Mountain: Critical issues

    International Nuclear Information System (INIS)

    Halstead, R.J.; Souleyrette, R.R.; Bartolo, R. di

    1991-01-01

    Transportation planning for a repository at Yucca Mountain is complicated because of uncertainty about the modes and numbers of nuclear waste shipments and because of uncertainty about the routes which will be used. There could be as many as 76,000 truck shipments, or as few as 1,060 dedicated train shipments, during repository operations. The site lacks rail access. Three rail access options currently under study range in length from 120 miles to more than 400 miles. The site is more than 100 miles from the Interstate highway system. The UNLV Transportation Research Center has evaluated three rail and four highway routes using a broad range of impact measures. This preliminary evaluation found that the routing options differ significantly regarding resident and non-resident populations, environmentally sensitive areas, accident rates, and other factors. Crosscutting issues include impacts on Nevada Indian tribes, potential conflicts with US Air Force operations, and future population growth in southern Nevada. Considerable additional analysis will be required prior to environmental impact statement scoping

    The Veterans Health Administration (VHA), of the U.S. Department of Veteran Affairs has instituted a medical record (EMR) that includes electronic documentation of all narrative components of the medical record. To support clinicians using the system, multiple efforts have been instituted to ease the creation of narrative reports. Although electronic documentation is easier to read and improves access to information, it also may create new and additional hazards for users. This study is the first step in a series of studies to evaluate the issues surrounding the creation and use of electronic documentation. Eighty-eight providers across multiple clinical roles were interviewed in 10 primary care sites in the VA system. Interviews were tape-recorded, transcribed and qualitatively analyzed for themes. In addition, specific questions were asked about perceived harm due to electronic documentation practices. Five themes relating to difficulties with electronic documentation were identified: 1) information overload; 2) hidden information; 3) lack of trust; 4) communication; 5) decision-making. Three providers reported that they knew of an incident where current documentation practices had caused patient harm and over 75% of respondents reported significant mis-trust of the system.

  15. MODERNIZING THE PRIVATE LAW. SOME KEY ISSUES IN THE RECENT DRAFT OF THE SPANISH COMMERCIAL CODE

    Directory of Open Access Journals (Sweden)

    Dan VELICU

    2016-05-01

    Full Text Available The last decades were dominated by the idea that an authentic process to modernize the private law means generally the unification of it by renouncing the distinction between civil and commercial law. A few European countries and some American states or provinces followed this path of the unification. However, beyond the will to change and improve the system one may reflect if this kind of modernization is actually really proper. Of course, there are lots of reasons for unification and reasons against it. Is there a possible and real alternative to this wave of unification? The draft of the Spanish commercial code could be a beginning point in order to settle this controversy. For the first time, the lawmakers are trying to replace the actual code with a new modernized one without renouncing the above mentioned distinction. Without claiming that we have entirely analyzed the topic, we propose a brief critical presentation of the major key issue of the draft.

    This paper presents preliminary analysis of a volcanic tuff repository containing a combination of low enrichment commercial spent nuclear fuels (SNF) and DOE-owned SNF packages. These SNFs were analyzed with respect to their criticality risks. Disposal of SNF packages containing significant fissile mass within a geologic repository must comply with current regulations relative to criticality safety during transportation and handling within operational facilities. However, once the repository is closed, the double contingency credits for criticality safety are subject to unremediable degradation, (e.g., water intrusion, continued presence of neutron absorbers in proximity to fissile material, and fissile material reconfiguration). The work presented in this paper focused on two attributes of criticality in a volcanic tuff repository for near-field and far-field scenarios: (1) scenario conditions necessary to have a criticality, and (2) consequences of a nuclear excursion that are components of risk. All criticality consequences are dependent upon eventual water intrusion into the repository and subsequent breach of the disposal package. Key criticality parameters necessary for a critical assembly are: (1) adequate thermal fissile mass, (2) adequate concentration of fissile material, (3) separation of neutron poison from fissile materials, and (4) sufficient neutron moderation (expressed in units of moderator to fissile atom ratios). Key results from this study indicated that the total energies released during a single excursion are minimal (comparable to those released in previous solution accidents), and the maximum frequency of occurrence is bounded by the saturation and temperature recycle times, thus resulting in small criticality risks

    Full Text Available The purpose of the research subject to this paper is to find proper solutions for the increase of the volume and efficiency in the field of commercial mediation. Starting from practical remarks, after an analysis of the substance, a new concept is suggested to be included and put into operation, namely the special commercial mediation, and a plead is made for its use in the current activity of alternative dispute resolution. The first major objective of this paper is to demonstrate once again the need and utility of mediation in the commercial field, insisting though on its remarkable specific nature. The second objective is, starting from the outlined differences between the commercial mediation and the classical mediation, to define and to conceptualize the special commercial mediation, as a separate branch of mediation. The third objective of this paper is to draw the regime of the newly defined category of commercial mediation from a regulatory point of view, of the implementation structure and techniques as foreseen.

    Full Text Available ABSTRACT The objective of this paper is to analyze critical situations experienced by women entrepreneurs and understand how they have overcome such situations. The study contributes to the understanding of the issues related to the activities of women entrepreneurs and shows that the use of the critical incident technique is relevant to the development of research in the field of entrepreneurship. The data were collected using a specific form with 115 women participating in the study. The analysis of critical incidents showed that in addition to the practical issues regarding the management of their business, emotions are interconnected with their business development. Unlike international studies in the field, the critical incidents experienced by Brazilian women entrepreneurs overlap with personal aspects. The women involved in this study face emotional difficulties, but are also motivated by strong feelings of determination to overcome their problems.

  1. Validation issues for depletion and criticality analysis in burnup credit

    2001-01-01

    This paper reviews validation issues associated with implementation of burnup credit in transport, dry storage, and disposal. The issues discussed are ones that have been identified by one or more constituents of the United States technical community (national laboratories, licensees, and regulators) that have been exploring the use of burnup credit. There is not necessarily agreement on the importance of the various issues, which sometimes is what creates the issue. The broad issues relate to the paucity of available experimental data (radiochemical assays and critical experiments) covering the full range and characteristics of spent nuclear fuel in away-from-reactor systems. The paper will also introduce recent efforts initiated at Oak Ridge National Laboratory (ORNL) to provide technical information that can help better assess the value of different experiments. The focus of the paper is on experience with validation issues related to use of burnup credit for transport and dry storage applications. (author)

    2012-08-01

    Full Text Available Drylands cover about 40% of the terrestrial land surface and account for approximately 40% of global net primary productivity. Water is fundamental to the biophysical processes that sustain ecosystem function and food production, particularly in drylands where a tight coupling exists between ecosystem productivity, surface energy balance, biogeochemical cycles, and water resource availability. Currently, drylands support at least 2 billion people and comprise both natural and managed ecosystems. In this synthesis, we identify some current critical issues in the understanding of dryland systems and discuss how arid and semiarid environments are responding to the changes in climate and land use. The issues range from societal aspects such as rapid population growth, the resulting food and water security, and development issues, to natural aspects such as ecohydrological consequences of bush encroachment and the causes of desertification. To improve current understanding and inform upon the needed research efforts to address these critical issues, we identify some recent technical advances in terms of monitoring dryland water dynamics, water budget and vegetation water use, with a focus on the use of stable isotopes and remote sensing. These technological advances provide new tools that assist in addressing critical issues in dryland ecohydrology under climate change.

    Evans, Robert S.; Husser, Dewayne L.; Jensen, Russell R.; Kerr, John M.

    1994-07-01

    Particle-Bed Reactors (PBRs) potentially offer performance advantages for nuclear thermal propulsion, including very high power densities, thrust-to-weight ratios, and specific impulses. A key factor in achieving all of these is the development of a very-high-temperature fuel. The critical issues for all such PBR fuels are uranium loading, thermomechanical and thermochemical stability, compatibility with contacting materials, fission product retention, manufacturability, and operational tolerance for particle failures. Each issue is discussed with respect to its importance to PBR operation, its status among current fuels, and additional development needs. Mixed-carbide-based fuels are recommended for further development to support high-performance PBRs.

    1994-01-01

    Major initiatives are underway within DOE to recycle large volumes of scrap material generated during cleanup of the DOE Weapons Complex. These recycling initiatives are driven not only by the desire to conserve natural resources, but also by the recognition that shallow level burial is not a politically acceptable option. The Fernald facility is in the vanguard of a number of major DOE recycling efforts. These early efforts have brought issues to light that can have a major impact on the ability of Fernald and other major DOE sites to expand recycling efforts in the future. Some of these issues are; secondary waste deposition, title to material and radioactive contaminants, mixed waste generated during recycling, special nuclear material possession limits, cost benefit, transportation of waste to processing facilities, release criteria, and uses for beneficially reused products

    The Critical Issues Forum (CIF) funded by the US Department of Energy is a collaborative effort between the Science Education Team of Los Alamos National Laboratory (LANL) and New Mexico high schools to improve science education throughout the state of New Mexico as well as nationally. By creating an education relationship between the LANL with its unique scientific resources and New Mexico high schools, students and teachers participate in programs that increase not only their science content knowledge but also their critical thinking and problem-solving skills. The CIF program focuses on current, globally oriented topics crucial to the security of not only the US but to that of all nations. The CIF is an academic-year program that involves both teachers and students in the process of seeking solutions for real world concerns. Built around issues tied to LANL`s mission, participating students and teachers are asked to critically investigate and examine the interactions among the political, social, economic, and scientific domains while considering diversity issues that include geopolitical entities and cultural and ethnic groupings. Participants are expected to collaborate through telecommunications during the research phase and participate in a culminating multimedia activity, where they produce and deliver recommendations for the current issues being studied. The CIF was evaluated and found to be an effective approach for teacher professional training, especially in the development of skills for critical thinking and questioning. The CIF contributed to students` ability to integrate diverse disciplinary content about science-related topics and supported teachers in facilitating the understanding of their students using the CIF approach. Networking technology in CIF has been used as an information repository, resource delivery mechanism, and communication medium.

    We have designed flux transformers made of commercial BiSCCO tapes closed by soldering with normal metal. The magnetic field transfer function of the flux transformer was calculated as a function of the resistance of the soldered contacts. The performances of different kinds of wires were investigated for signal delocalization and gradiometry. We also estimated the noise introduced by the resistance and showed that the flux transformer can be used efficiently for weak magnetic field detection down to 1 Hz.

  11. Critical issues in the history, philosophy, and sociology of astrobiology.

    2012-10-01

    Fifty years after serious scientific research began in the field of exobiology, and forty years after serious historical research began on the subject of extraterrestrial life, this paper identifies and examines some of the most important issues in the history, philosophy, and sociology of what is today known as astrobiology. As in the philosophy of science in general, and in the philosophies of particular sciences, critical issues in the philosophy and sociology of astrobiology are both stimulated and illuminated by history. Among those issues are (1) epistemological issues such as the status of astrobiology as a science, the problematic nature of evidence and inference, and the limits of science; (2) metaphysical/scientific issues, including the question of defining the fundamental concepts of life, mind, intelligence, and culture in a universal context; the role of contingency and necessity in the origin of these fundamental phenomena; and whether or not the universe is in some sense fine-tuned for life and perhaps biocentric; (3) societal issues such as the theological, ethical, and worldview impacts of the discovery of microbial or intelligent life; and the question of whether the search for extraterrestrial life should be pursued at all, and with what precautions; and (4) issues related to the sociology of scientific knowledge, including the diverse attitudes and assumptions of different scientific communities and different cultures to the problem of life beyond Earth, the public "will to believe," and the formation of the discipline of astrobiology. All these overlapping issues are framed by the concept of cosmic evolution-the 13.7 billion year Master Narrative of the Universe-which may result in a physical, biological, or postbiological universe and determine the long-term destiny of humanity.

In this paper we provide a critical analysis of the technological and economic issues associated with high-average power FEL operation from the UV to near IR. The project of IR FEL for the Siberian Center of photochemical researches is described. The distinguished features of this project are the use of the race-track microtron-recuperator and the {open_quotes}electron output of radiation{close_quotes}. The building for the machine is under reconstruction now. About half of hardware has been manufactured. The assembly of installation began.

  13. Critical issues and experimental examination on sawtooth and disruption physics

    International Nuclear Information System (INIS)

    Itoh, K.; Itoh, S.; Fukuyama, A.; Tsuji, S.

    1992-06-01

    The catastrophic phenomena which are associated with the major disruption and sawtooth contain three key processes: (1) Sudden acceleration of the growth of the helical deformation, (2) Central electron temperature crash, and (3) Rearrangement of the plasma current. Based on the theoretical model that the magnetic stochasticity plays a key role in these processes, the critical issues and possible experimental tests are proposed. Present experimental observations would be sufficient to study the detailed sequences and causes. Though models may not be complete the comparison with experiments improves understandings. (author)

    Plasma-materials interactions are a dominant driving force in the design of fusion power reactors. This paper presents a summary of plasma-materials interactions research. Emphasis is placed on critical aspects related to reactor design. Particular issues to be addressed are plasma edge characterization, hydrogen recycle, impurity introduction, and coating development. Typical wall fluxes in operating magnetically confined devices are summarized. Recent calculations of tritium inventory and first wall permeation, based on laboratory measurements of hydrogen recycling, are given for various reactor operating scenarios. Impurity introduction/wall erosion mechanisms considered include sputtering, chemical erosion, and evaporation (melting). Finally, the advanced material development for in-vessel components is discussed. (author)

    High-level radioactive waste from nuclear fuels processing is stored in underground waste storage tanks located in the tank farms on the Hanford Site. Waste in tank storage contains low concentrations of fissile isotopes, primarily U-235 and Pu-239. The composition and the distribution of the waste components within the storage environment is highly complex and not subject to easy investigation. An important safety concern is the preclusion of a self-sustaining neutron chain reaction, also known as a nuclear criticality. A thorough technical evaluation of processes, phenomena, and conditions is required to make sure that subcriticality will be ensured for both current and future tank operations. Subcriticality limits must be based on considerations of tank processes and take into account all chemical and geometrical phenomena that are occurring in the tanks. The important chemical and physical phenomena are those capable of influencing the mixing of fissile material and neutron absorbers such that the degree of subcriticality could be adversely impacted. This report describes a logical approach to resolving the criticality safety issues in the Hanford waste tanks. The approach uses a structured logic diagram (SLD) to identify the characterization needed to quantify risk. The scope of this section of the report is limited to those branches of logic needed to quantify the risk associated with a criticality event occurring. The process is linked to a conceptual model that depicts key modes of failure which are linked to the SLD. Data that are needed include adequate knowledge of the chemical and geometric form of the materials of interest. This information is used to determine how much energy the waste would release in the various domains of the tank, the toxicity of the region associated with a criticality event, and the probability of the initiating criticality event

    1987-06-01

    This paper will address the issues raised by the "commercialization" of holography that has taken place since the mid-1980's. The paper examines the range of these issues as they apply to the practise of fine-art holography, the author's area of expertise. The effect of mass-produced and readily available holograms on the public's perception of holographic art will be discussed in light of the presence of holographic images on credit cards and national magazine covers. A major portion of the paper will examine the specific issues raised by the commercialization and mass production of holographic art. These issues will centre on the professional, ethical and artistic implications of commercialized holography as they apply to the practice of fine art holography.

    High-End computing (HEC) has been a driver for advances in science and engineering for the past four decades. Increasingly HEC has become a significant element in the national security, economic vitality, and competitiveness of the United States. Advances in HEC provide results that cut across traditional disciplinary and organizational boundaries. This program provides opportunities to share information about HEC systems and computational techniques across multiple disciplines and organizations through conferences and exhibitions of HEC advances held in Washington DC so that mission agency staff, scientists, and industry can come together with White House, Congressional and Legislative staff in an environment conducive to the sharing of technical information, accomplishments, goals, and plans. A common thread across this series of conferences is the understanding of computational science and applied mathematics techniques across a diverse set of application areas of interest to the Nation. The specific objectives of this program are: Program Objective 1. To provide opportunities to share information about advances in high-end computing systems and computational techniques between mission critical agencies, agency laboratories, academics, and industry. Program Objective 2. To gather pertinent data, address specific topics of wide interest to mission critical agencies. Program Objective 3. To promote a continuing discussion of critical issues in high-end computing. Program Objective 4.To provide a venue where a multidisciplinary scientific audience can discuss the difficulties applying computational science techniques to specific problems and can specify future research that, if successful, will eliminate these problems.

  20. Critical gases for critical issues: CO2 technologies for oral drug delivery.

    Danan, Hana; Esposito, Pierandrea

    2014-02-01

    In recent years, CO2-based technologies have gained considerable interest in the pharmaceutical industry for their potential applications in drug formulation and drug delivery. The exploitation of peculiar properties of gases under supercritical conditions has been studied in the last 20 years with mixed results. Promising drug-delivery technologies, based on supercritical CO2, have mostly failed when facing challenges of industrial scaleability and economical viability. Nevertheless, a 'second generation' of processes, based on CO2 around and below critical point has been developed, possibly offering technology-based solutions to some of the current issues of pharmaceutical development. In this review, we highlight the most recent advancements in this field, with a particular focus on the potential of CO2-based technologies in addressing critical issues in oral delivery, and briefly discuss the future perspectives of dense CO2-assisted processes as enabling technologies in drug delivery.

    2011-11-01

    As a result of recent events, including natural disasters and pandemics, mass critical care planning has become a priority. In general, planning involves limiting the scope of disasters, increasing the supply of medical resources, and allocating scarce resources. Entities at varying levels have articulated ethical frameworks to inform policy development. In spite of this increased focus, children have received limited attention. Children require special attention because of their unique vulnerabilities and needs. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subgroups by topic area and performed literature reviews of MEDLINE and Ovid databases. Draft documents were subsequently developed and revised based on the feedback from the Task Force. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. This document reflects expert input from the Task Force in addition to the most current medical literature. The Ethics Subcommittee recommends that surge planning seek to provide resources for children in proportion to their percentage of the population or preferably, if data are available, the percentage of those affected by the disaster. Generally, scarce resources should be allocated on the basis of need, benefit, and the conservation of resources. Estimates of need, benefit, and resource utilization may be more subjective or objective. While the

    People with stomas who have either been cured of cancer or are living with cancer have achieved good interrelationships among the three issues of"establishing self-care","dealing with stoma complications", and"accepting stomas", and they are maintaining stable physical and mental states.However, self-care may become difficult due to stoma complications and adverse events caused by chemotherapy and radiation therapy in the cancer treatment period, and in advanced phases of cancer serious stoma complications may occur due to deterioration of general condition and advancing cancer. Therefore, there is a risk that those stable physical and mental states will collapse.In order to deal with this critical state, in the cancer treatment period, stoma skin care is used for handling skin problems around the stoma, and for adverse events such as hand-and-foot syndrome, braces that are easy to operate are chosen from among various types of stoma braces in order to cover impediments.During advanced phases of cancer, care is conducted with the main priority placed on physical stability in order to ensure that the three major complications of stoma varicose veins, stoma prolapse, and parastomal hernia do not worsen and significantly affect general condition and daily life.Stoma outpatient treatment that provides lifelong support for such issues, and the existence of skin- and excretion-care certified nurses who provided highly specialized selfcare support, are extremely important for cancer survivors with stomas.

  3. Critical safety issues in the design of fusion machines

    International Nuclear Information System (INIS)

    Kramer, W.

    1991-01-01

    In the course of developing fusion machines both general safety considerations and safety assessments for the various components and systems of actual machines increase in number and become more and more coherent. This is particularly true for the NET/ITER projects where safety analysis plays an increasing role for the design of the machine. Since in a D/T tokamak the radiological hazards will be dominant basic radiological safety objectives are discussed. Critical safety issues as identified in particular by the NET/ITER community are reviewed. Subsequently, issues of major concern are considered both for normal operation and for conceivable accidents. The following accidents are considered to be crucial: Loss of cooling in plasma facing components, loss of vacuum, tritium system failure, and magnet system failure. To mitigate accident consequences a confinement concept based on passive features and multiple barriers including detritiation and filtering has to be applied. The reactor building as final barrier needs special attention to cope with both internal and external hazards. (orig.)

    1998-01-01

    The objective of this research was to tackle several problems that are currently of great importance to NASA. In a liquid rocket engine several complex processes take place that are not thoroughly understood. Droplet evaporation, turbulence, finite rate chemistry, instability, and injection/atomization phenomena are some of the critical issues being encountered in a liquid rocket engine environment. Pulse Detonation Engines (PDE) performance, combustion chamber instability analysis, 60K motor flowfield pattern from hydrocarbon fuel combustion, and 3D flowfield analysis for the Combined Cycle engine were of special interest to NASA. During the summer of 1997, we made an attempt to generate computational results for all of the above problems and shed some light on understanding some of the complex physical phenomena. For this purpose, the Liquid Thrust Chamber Performance (LTCP) code, mainly designed for liquid rocket engine applications, was utilized. The following test cases were considered: (1) Characterization of a detonation wave in a Pulse Detonation Tube; (2) 60K Motor wall temperature studies; (3) Propagation of a pressure pulse in a combustion chamber (under single and two-phase flow conditions); (4) Transonic region flowfield analysis affected by viscous effects; (5) Exploring the viscous differences between a smooth and a corrugated wall; and (6) 3D thrust chamber flowfield analysis of the Combined Cycle engine. It was shown that the LTCP-2D and LTCP-3D codes are capable of solving complex and stiff conservation equations for gaseous and droplet phases in a very robust and efficient manner. These codes can be run on a workstation and personal computers (PC's).

    Within the framework of the feasibility study on commercialized fast reactor cycle systems (hereafter described as F/S), the safety design principle is investigated and several kinds of design studies are now in progress. Among the designs for liquid-metal cooled fast reactor (LMR), the advanced loop type sodium cooled fast reactor (FR) is one of the promising candidate as future commercialized LMR. In this paper, the safety related research and development (R and D) issues necessary to achieve the safety design are described along the defence-in-depth principle, taking account of not only the system characteristics of the advanced loop concepts but also design studies and R and D experiences so far. Safety issues related to the hypothetical core disruptive accidents (CDA) are emphasized both from the prevention and mitigation. A re-criticality free core concept with a special fuel assembly is pursued by performing both analytical and experimental efforts, in order to realize the rational design and to establish easy-to-understand safety logic. Sodium related issues are also given to ensure plant availability and to enhance the acceptability to the public. (authors)

    Full Text Available Valuation for secured lending is required when an interest in real property is used as security for a loan. The outcome of such valuation will help the lending institution to achieve commercial prudence in lending as well as avoid taking undue risk. This paper examines the issues and developments in the valuation of urban commercial properties in Nigeria for secured lending purposes. It argues that due to the volatile nature of the Nigerian economy, coupled with the linkage between the economy and commercial property markets, the maximum amount of loan to be granted by lenders in the country using interest in commercial property as collateral should be based on the Mortgage Lending Value (MLV and not the Market Value (MV of the property, although the market value should also be reported in the valuation. A case study is used to demonstrate the valuation. It further contends that since the inputs for determining the MLV of a commercial property must be derived from long-term trends in the property and financial markets, it is more stable than MV when used to determine the maximum amount of mortgage loan to be granted by a lender. It concludes that the stability of the MLV makes it more reliable than the MV in achieving commercial prudence in mortgage lending as it fits into the long-term nature of mortgage loan repayment.

    2013-12-01

    This special issue is the fourth of its kind in Journal of Geophysics and Engineering , containing studies and applications of geophysical methodologies and sensing technologies for the knowledge, conservation and security of products of human activity ranging from civil infrastructures to built and cultural heritage. The first discussed the application of novel instrumentation, surface and airborne remote sensing techniques, as well as data processing oriented to both detection and characterization of archaeological buried remains and conservation of cultural heritage (Eppelbaum et al 2010). The second stressed the importance of an integrated and multiscale approach for the study and conservation of architectural, archaeological and artistic heritage, from SAR to GPR to imaging based diagnostic techniques (Masini and Soldovieri 2011). The third enlarged the field of analysis to civil engineering structures and infrastructures, providing an overview of the effectiveness and the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques (Masini et al 2012). As a whole, the special issue put in evidence the factors that affect the choice of diagnostic strategy, such as the material, the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment). In order to complete the overview of the application fields of sensing technologies this issue has been dedicated to monitoring of cultural heritage and critical infrastructures to address safety and security issues. Particular attention has been paid to the data processing methods of different sensing techniques, from infrared thermography through GPR to SAR. Cascini et al (2013) present the effectiveness of a

    One of the most promising materials for low-cost thin film photovoltaic cells is copper indium selenide (CuInSe{sub 2} or CIS). As with any new material, successful commercialization of CIS photovoltaic (PV) technology will require attention to environmental issues related to the sources of raw materials, their usage, and the disposal and/or recycling of products at the end of their useful life. This paper focuses on three specific environmental issues related to CIS technology: (i) Economics of the use and re-use of materials; (ii) regulations on environmental disposal and waste handling, and (iii) logistics and economics of recycling and disposing of products by industries faced with comparable environmental issues.

    2007-01-01

    The purpose of this calculation report, Range of Applicability and Bias Determination for Postclosure Criticality of Commercial Spent Nuclear Fuel, is to validate the computational method used to perform postclosure criticality calculations. The validation process applies the criticality analysis methodology approach documented in Section 3.5 of the Disposal Criticality Analysis Methodology Topical Report. The application systems for this validation consist of waste packages containing transport, aging, and disposal canisters (TAD) loaded with commercial spent nuclear fuel (CSNF) of varying assembly types, initial enrichments, and burnup values that are expected from the waste stream and of varying degree of internal component degradation that may occur over the 10,000-year regulatory time period. The criticality computational tool being evaluated is the general-purpose Monte Carlo N-Particle (MCNP) transport code. The nuclear cross-section data distributed with MCNP 5.1.40 and used to model the various physical processes are based primarily on the Evaluated Nuclear Data File/B Version VI (ENDF/B-VI) library. Criticality calculation bias and bias uncertainty and lower bound tolerance limit (LBTL) functions for CSNF waste packages are determined based on the guidance in ANSI/ANS 8.1-1998 (Ref. 4) and ANSI/ANS 8.17-2004 (Ref. 5), as described in Section 3.5.3 of Ref. 1. The development of this report is consistent with Test Plan for: Range of Applicability and Bias Determination for Postclosure Criticality. This calculation report has been developed in support of licensing activities for the proposed repository at Yucca Mountain, Nevada, and the results of the calculation may be used in the criticality evaluation for CSNF waste packages based on a conceptual TAD canister.

    Full Text Available The article is dedicated to the research of the current development state of commercial activity in Ukraine. The author determines that the most researches conducted about the commercial activity in Ukraine are connected with the theoretical substantiation of management process. In the process of the study it is established that the commercial activity is a component of economic activity of those enterprises which sell their own made products to the consumers who purchase goods for further sale and to the consumers who are specialized in retail trade. On the base of state statistical information, it is determined the dynamics of formation of goods turnover and the produced services by domestic economic entities; the indices of resource providing of wholesale and retail trading enterprises are counted. It is determined that the development of the commercial activity at Ukrainian enterprises is connected with the development of the country’s economy and directed to the needs and demands of the market, a separate buyer of goods and services. The analysis of the current studies in the sphere of commercial activity of trade enterprises made it possible to single out the peculiarities of trading activity of producers of goods, wholesale mediators and retail trade networks according to the following signs: the amounts of sales, the chain of activity, the term of forming incomes, the place of disposition, specialization. The paper determines the peculiarities of commercial activity according to the types of trading enterprises and this allows to form the problems and prospects of their development. The common issues for the development of enterprises’ commercial activity are the lack of sufficient amount of financial resources to provide the needs of the selling processes, the low business partners’ activity, competitors’ breach of the rules for the commercial activity. The common prospects for the development of enterprises’ commercial

    This document specifies the critical characteristics for Commercial Grade Items (CGI) procured for PFP's Vault Operations system as required by HNF-PRO-268 and HNF-PRO-1819. These are the minimum specifications that the equipment must meet in order to perform its safety function. The changes in these specifications have no detrimental effect on the descriptions and parameters related to handling plutonium solids in the authorization basis. Because no parameters or sequences exceed the limits described in the authorization bases, no accident or abnormal conditions are affected. The specifications prescribed in this critical characteristics document do not represent an unreviewed safety question

  2. Alternate measurements of benefit to criticality issues at Hanford

    Energy Technology Data Exchange (ETDEWEB)

    Toffer, H.; Cabrilla, D.E.

    1997-06-01

    Measurements in a critical mass facility, such as the Los Alamos Critical Experiments Facility, could be performed on simulated nuclear waste materials that would provide important critical mass information and concurrently provide a calibration of alternate measurement techniques. In addition to criticality information, the measurements could also provide a better assessment of diluent material/neutron interaction cross sections. An Hanford, large quantities of fissionable materials are dispersed in tanks, fuel storage pools, and in solid waste. Although the fissionable materials are well diluted by a variety of neutron-moderating and -absorbing substances, it is difficult to assess the margin of subcriticality. A number of measurement approaches are proposed that will either help determine fissionable material concentrations, distributions, or provide a direct measure of subcriticality. The methods under consideration involve passive neutron counting, active neutron measurements, pulse neutron applications, neutron noise analyses, and cover gas evaluations. Active neutron measurements can also provide insight into the determination of neutron absorber concentrations. Efforts are underway to test some of the methods in actual waste tank environments and geometries. It is important that these methods be tested and calibrated in a critical mass facility.

  11. The value of criticality: Gauging issues in supply nets

    Directory of Open Access Journals (Sweden)

    Jochen Speyerer

    2005-06-01

    Full Text Available Modern day supply chains encompass both geographically disparate activities and planning processes for multiple companies or various interdependent time horizons. To be able to effectively manage these supply chains it is not only necessary to strategically plan the future of the underlying network of participating companies but also to schedule and monitor the ongoing production and logistics activities on a regular basis. Unfortunately, available information systems do not provide an adequate way to handle disruptions. If at all, they employ inter-organizational workflows to keep track of activities and notify a pre-set recipient in case something goes wrong. But in order to be able to focus their attention on urgent problems, managers need a means to gauge the criticality of a symptom. This paper tries to fill this gap by introducing a Value of Criticality (VoC that indicates how serious the faced deviation really is.

  14. The environmental Kuznets curve (EKC) theory. Part B: Critical issues

    International Nuclear Information System (INIS)

    Kaika, Dimitra; Zervas, Efthimios

    2013-01-01

    According to the environmental Kuznets curve (EKC) theory, the process of economic growth is expected to limit the environmental degradation created in the early stages of development. The first article of this study reviews the empirical studies examining various factors, other than income, that may lead to an EKC-pattern. The current article reviews in the first part the major critiques on the EKC-speculation which relate to the following issues: the normal distribution of world income, the feedback from environmental degradation to economic growth, the characteristics of the pollutant in question, various econometric issues, the evolution of consumption when income rises and the assumption about a common developmental pattern in all countries. The second part discusses additional matters reported indirectly in the literature and/or must be further examined. There are doubts whether the GDP-series captures the transition of production to the three productive sectors in empirical estimations and whether services are less polluting compared to industry activities. Finally, the original Kuznets-theory, which laid the groundwork for the EKC-concept, does not seem to solve income inequality problems. - Highlights: • The basic critiques on the EKC-concept are presented. • Some additional issues, not explicitly presented in the literature, must be further examined. • The examination of such critiques is essential to define the validity-bounds of the EKC-concept. • The construction of structural models comes up to be more urgent than ever

    2000-06-01

    Informed consent (IC), a fundamental principle of ethics in medical research, is recognized as a vital component of HIV vaccine trials. There are different notions of IC, some legally based and others based on ethics. It is argued that, though legal indemnity is necessary, vaccine trials should be founded on fully ethical considerations. Various contentious aspects of IC are examined, especially the problem of social desirability and of adequate comprehension. The need for sensitivity to cultural norms in implementing IC procedures is critically reviewed, and some of the potential conflict between ethos and ethics is considered. The transmission of information is examined as a particular aspect of IC in HIV vaccine trials.

  17. Indoor air quality issues related to the acquisition of conservation in commercial buildings

    Energy Technology Data Exchange (ETDEWEB)

    Baechler, M.C.; Hadley, D.L.; Marseille, T.J.

    1990-09-01

    The quality of indoor air in commercial buildings is dependent on the complex interaction between sources of indoor pollutants, environmental factors within buildings such as temperature and humidity, the removal of air pollutants by air-cleaning devices, and the removal and dilution of pollutants from outside air. To the extent that energy conservation measures (ECMs) may affect a number of these factors, the relationship between ECMs and indoor air quality is difficult to predict. Energy conservation measures may affect pollutant levels in other ways. Conservation measures, such as caulking and insulation, may introduce sources of indoor pollutants. Measures that reduce mechanical ventilation may allow pollutants to build up inside structures. Finally, heating, ventilation, and air-conditioning (HVAC) systems may provide surface areas for the growth of biogenic agents, or may encourage the dissemination of pollutants throughout a building. Information about indoor air quality and ventilation in both new and existing commercial buildings is summarized in this report. Sick building syndrome and specific pollutants are discussed, as are broader issues such as ventilation, general mitigation techniques, and the interaction between energy conservation activities and indoor air quality. Pacific Northwest Laboratory (PNL) prepared this review to aid the Bonneville Power Administration (Bonneville) in its assessment of potential environmental effects resulting from conservation activities in commercial buildings. 76 refs., 2 figs., 19 tabs.

  18. Measurement Issues for Energy Efficient Commercial Buildings: Productivity and Performance Uncertainties

    Energy Technology Data Exchange (ETDEWEB)

    Jones, D.W.

    2002-05-16

    In previous reports, we have identified two potentially important issues, solutions to which would increase the attractiveness of DOE-developed technologies in commercial buildings energy systems. One issue concerns the fact that in addition to saving energy, many new technologies offer non-energy benefits that contribute to building productivity (firm profitability). The second issue is that new technologies are typically unproven in the eyes of decision makers and must bear risk premiums that offset cost advantages resulting from laboratory calculations. Even though a compelling case can be made for the importance of these issues, for building decision makers to incorporate them in business decisions and for DOE to use them in R&D program planning there must be robust empirical evidence of their existence and size. This paper investigates how such measurements could be made and offers recommendations as to preferred options. There is currently little systematic information on either of these concepts in the literature. Of the two there is somewhat more information on non-energy benefits, but little as regards office buildings. Office building productivity impacts can be observed casually, but must be estimated statistically, because buildings have many interacting attributes and observations based on direct behavior can easily confuse the process of attribution. For example, absenteeism can be easily observed. However, absenteeism may be down because a more healthy space conditioning system was put into place, because the weather was milder, or because firm policy regarding sick days had changed. There is also a general dearth of appropriate information for purposes of estimation. To overcome these difficulties, we propose developing a new data base and applying the technique of hedonic price analysis. This technique has been used extensively in the analysis of residential dwellings. There is also a literature on its application to commercial and industrial

  19. SCALE-4 Analysis of LaSalle Unit 1 BWR Commercial Reactor Critical Configurations

    International Nuclear Information System (INIS)

    Gauld, I.C.

    2000-01-01

    Five commercial reactor criticals (CRCs) for the LaSalle Unit 1 boiling-water reactor have been analyzed using KENO V.a, the Monte Carlo criticality code of the SCALE 4 code system. The irradiated fuel assembly isotopics for the criticality analyses were provided by the Waste Package Design team at the Yucca Mountain Project in the US, who performed the depletion calculations using the SAS2H sequence of SCALE 4. The reactor critical measurements involved two beginning-of-cycle and three middle-of-cycle configurations. The CRCs involved relatively low-cycle burnups, and therefore contained a relatively high gadolinium poison content in the reactor assemblies. This report summarizes the data and methods used in analyzing the critical configurations and assesses the sensitivity of the results to some of the modeling approximations used to represent the gadolinium poison distribution within the assemblies. The KENO V.a calculations, performed using the SCALE 44GROUPNDF5 ENDF/B-V cross-section library, yield predicted k eff values within about 1% Δk/k relative to reactor measurements for the five CRCs using general 8-pin and 9-pin heterogeneous gadolinium poison pin assembly models

    1996-01-01

    This research was undertaken to provide NASA with a survey of state-of-the-art techniques using in industrial and academia to provide safe, reliable, and maintainable software to drive large systems. Such systems must match the complexity and strict safety requirements of NASA's shuttle system. In particular, the Launch Processing System (LPS) is being considered for replacement. The LPS is responsible for monitoring and commanding the shuttle during test, repair, and launch phases. NASA built this system in the 1970's using mostly hardware techniques to provide for increased reliability, but it did so often using custom-built equipment, which has not been able to keep up with current technologies. This report surveys the major techniques used in industry and academia to ensure reliability in large and critical computer systems.

  1. Critical Design Issues of Tokamak Cooling Water System of ITER's Fusion Reactor

    International Nuclear Information System (INIS)

    Kim, Seokho H.; Berry, Jan

    2011-01-01

    U.S. ITER is responsible for the design, engineering, and procurement of the Tokamak Cooling Water System (TCWS). The TCWS transfers heat generated in the Tokamak to cooling water during nominal pulsed operation 850 MW at up to 150 C and 4.2 MPa water pressure. This water contains radionuclides because impurities (e.g., tritium) diffuse from in-vessel components and the vacuum vessel by water baking at 200 240 C at up to 4.4MPa, and corrosion products become activated by neutron bombardment. The system is designated as safety important class (SIC) and will be fabricated to comply with the French Order concerning nuclear pressure equipment (December 2005) and the EU Pressure Equipment Directive using ASME Section VIII, Div 2 design codes. The complexity of the TCWS design and fabrication presents unique challenges. Conceptual design of this one-of-a-kind cooling system has been completed with several issues that need to be resolved to move to next stage of the design. Those issues include flow balancing between over hundreds of branch pipelines in parallel to supply cooling water to blankets, determination of optimum flow velocity while minimizing the potential for cavitation damage, design for freezing protection for cooling water flowing through cryostat (freezing) environment, requirements for high-energy piping design, and electromagnetic impact to piping and components. Although the TCWS consists of standard commercial components such as piping with valves and fittings, heat exchangers, and pumps, complex requirements present interesting design challenges. This paper presents a brief description of TCWS conceptual design and critical design issues that need to be resolved.

  2. Critical review of LEED system for rating sustainability of architecture of commercial interiors

    Full Text Available The LEED rating system for sustainability of architecture has gained large marketing potential in USA and became one of main ways American builders are attacking ecological challenges. In this paper the LEED rating system for commercial interiors is critically reviewed, pointing out its positive - focus on integrated design process - and negative impacts - low thresholds for highest ratings and tendency to gain LEED rating with projects that hardly pass the thresholds, largely neglecting the principles of energy efficiency. Based on a few prominent LEED platinum examples, the beginnings of a LEED style of designing interiors in historical landmark buildings are pointed out as well.

  3. Culture, demographics, and critical care issues: an overview.

    Science.gov (United States)

    Núñez, Germán R

    2003-10-01

    The population dynamic and the immigration trends in the United States continue to challenge health care professionals who each day must serve an increasingly diverse population. Today's physicians must not only have a solid background in medical sciences but they must also have knowledge of how culture, race, and ethnicity impact how patients view and accept traditional Western practices. Whether doctors and patients are close in the "context spectrum" will often determine their ability to communicate beyond the spoken language. According to a report of the American Medical Association, by the year 2000, out of a total 812,770 physicians, only 2.5% were Black, 3.5% Hispanic, and 8.9% Asian. Only a fraction of a percent was American Native/Alaskan Native. Therefore, the majority of the physicians are Caucasian, and it could be assumed that they would likely be accustomed to high-context communication styles. The gross of the demographic changes and population increases in the United States during the past 10 years can be attributed to immigration from regions of the world where low-context communication styles are prevalent. Such differences between physicians and patients can create difficult, tense situations in an already charged atmosphere as can be that of a critical care unit.

  4. Energy use management: the critical issues of interdependency and indeterminateness

    International Nuclear Information System (INIS)

    Davos, C.A.

    1982-01-01

    The translation of energy concerns into effective policies under a democratic regime is currently impaired by two interrelated factors: (1) the interdependency of energy goals with most of society's other concerns and (2) the indeterminateness of both the scientific evidence and public interest.

  5. Some critical environmental issues of the energy discussions

    2001-01-01

    There are two complementary approaches to studying the environmental effects of fuel use and energy conversion. The first is to be completely systematic and to follow through each technology in great detail, and itemise each impact, whether large or small. The second, followed here, is to pick out those items that either dominate the risk or impact, or dominate the public perception therefore, and try to understand them in some detail. I pick the following that I believe are the most important environmental issues today: 1 What is the effect of particulate air pollution on today's levels? 2 What is the probability that carbon dioxide emissions will cause global warming? 3 Can we use this energy source in a sustainable fashion over several millennia? I will spend much of the space on a discussion of these three. However, there are a number of other items that some group or another think are important. They must also be considered to sufficient extent to persuade everyone involved that indeed they are less important. These include: 4 What is the probability and effect of a severe nuclear power accident? 5 Why is there public concern about nuclear waste although it is not justified by the calculations? 6 Why are hydroelectric dams not as universally popular as they were? 7 Can we avoid the proliferation of bombs using plutonium if we have a nuclear power program? 8 Can we reduce the cost of electricity from nuclear power to what is was 25 years ago?

    The translation of energy concerns into effective policies under a democratic regime is currently impaired by two interrelated factors: the interdependency of energy goals with most of society's other concerns and the indeterminateness of both the scientific evidence and public interest. Some of the manifestations of the failure to address these factors are the prevailing energy policy uncertainties and the polarization of values, issues and research efforts. Awareness of this reality has not prevented, however, the suggestion of policies the majority of which either neglect the synergistic effect of the factors or depend for their legitimization on principles incompatible with democratic decision-making. Systematic examination of the web of interdependencies and of the scientific and public interest indeterminateness supports the assertion that the effectiveness of energy use management will depend on: supplementing quantitative research with qualitative evaluation of scientific and public values; synthesizing the findings of the numerous currently performed analyses; and substituting the paternalistic dictates of scientists and special interest groups as the basis for policy decision-making with a participatory process that will aim to maximize the accord among all interested in, and/or impacted by, energy policies.

    Photovoltaics technology is rapidly evolving towards a new generation of low-cost thin film technologies. One of the most promising materials in this new generation is copper indium selenide (CuInSe{sub 2} or CIS). As with any new material, successful commercialization of CIS photovoltaic (PV) technology will require attention to environmental, health and safety issues, including consideration of the sources, usage, and end-of-product-life disposal and/or recycling of the constituent materials. This work focuses on three specific environmental, health and safety (EH and S) issues related to CIS PV: (1) economics are analyzed to determine their impact on materials use and re-use; (2) Federal and California State environmental disposal and waste handling regulations are analyzed to evaluate their impact on PV module manufacturing and end-of-life module handling; and (3) the logistics and economics of product recycling and waste disposal by industries with comparable EH and S issues are examined to quantify the corresponding options available for handling, disposing of and/or recycling manufacturing by-products and end-of-life modules.

    Organizational changes focused on process orientation are taking place among Swedish nuclear power plants, aiming at improving the operation. The Swedish Nuclear Power Inspectorate has identified a need for increased knowledge within the area for its regulatory activities. In order to analyze what process orientation imply for nuclear power plant safety a number of questions must be asked: 1. How is safety in nuclear power production created currently? What significance does the functional organization play? 2. How can organizational forms be analysed? What consequences does quality management have for work and for the enterprise? 3. Why should nuclear power plants be process oriented? Who are the customers and what are their customer values? Which customers are expected to contribute from process orientation? 4. What can one learn from process orientation in other safety critical systems? What is the effect on those features that currently create safety? 5. Could customer values increase for one customer without decreasing for other customers? What is the relationship between economic and safety interests from an increased process orientation? The deregulation of the electricity market have caused an interest in increased economic efficiency, which is the motivation for the interest in process orientation. among other means. It is the nuclear power plants' owners and the distributors (often the same corporations) that have the strongest interest in process orientation. If the functional organization and associated practices are decomposed, the prerequisites of the risk management regime changes, perhaps deteriorating its functionality. When nuclear power operators consider the introduction of process orientation, the Nuclear Power Inspectorate should require that 1. The operators perform a risk analysis beforehand concerning the potential consequences that process orientation might convey: the analysis should contain a model specifying how safety is currently

    Full Text Available Abstract Background There are many challenges involved in running randomised controlled dietary intervention trials that investigate health outcomes. The aim of this paper was to evaluate the recruitment process, retention of participants and challenges faced in our dairy intervention trial, and to provide strategies to combat the difficulties of running long-term dietary intervention trials. Methods A 12-month, randomised, two-way crossover study was conducted in overweight adults with habitually low dairy food consumption to assess the effects of a high dairy intake (4 servings of reduced-fat dairy per day compared with a low dairy intake (1 serving of reduced-fat dairy per day on measures of cardiometabolic and cognitive health. On completion of the high dairy intake phase, each participant was interviewed about their experience in the trial and responses were used to evaluate the key issues for study participants. Results Although the recruitment target was achieved, high rates of attrition (49.3% and difficulties maintaining participant compliance (reported by 37.8% of participants were major threats to the viability of the study. Factors that contributed to the high attrition included inability to comply with the dietary requirements of the study protocol (27.0%, health problems or medication changes (24.3% and time commitment (10.8%. Conclusion Attrition and adherence to study requirements present challenges to trials requiring longer-term dietary change. Including a run-in period to further assess the motivation, commitment and availability of participants, maintaining regular contact with participants during control phases, minimising time commitment, providing flexibility with dietary requirements, facilitating positive experiences, and stringent monitoring of diet are some key recommendations for future dietary intervention trials.

  11. Critical Issues in the Philosophy of Astronomy and Cosmology

    Although the philosophy of science and of specific sciences such as physics, chemistry, and biology are well-developed fields with their own books and journals, the philosophy of astronomy and cosmology have received little systematic attention. At least six categories of problems may be identified in the astronomical context: 1) the nature of reasoning, including the roles of observation, theory, simulation, and analogy, as well as the limits of reasoning, starkly evident in the anthropic principle, fine-tuning, and multiverse controversies; 2) the often problematic nature of evidence and inference, especially since the objects of astronomical interest are for the most part beyond experiment and experience;3) the influence of metaphysical preconceptions and non-scientific worldviews on astronomy, evidenced, for example in the work of Arthur S. Eddington and many other astronomers; 4) the epistemological status of astronomy and its central concepts, including the process of discovery, the problems of classification, and the pitfalls of definition (as in planets); 5) the role of technology in shaping the discipline of astronomy and our view of the universe; and 6) the mutual interactions of astronomy and cosmology with society over time. Discussion of these issues should draw heavily on the history of astronomy as well as current research, and may reveal an evolution in approaches, techniques, and goals, perhaps with policy relevance. This endeavor should also utilize and synergize approaches and results from philosophy of science and of related sciences such as physics (e.g. discussions on the nature of space and time). Philosophers, historians and scientists should join this new endeavor. A Journal of the Philosophy of Astronomy and Cosmology (JPAC) could help focus attention on their studies.

  12. Mapping Commercial Web 2.0 Worlds: Towards a New Critical Ontogenesis

    Directory of Open Access Journals (Sweden)

    Kenneth Werbin

    2009-01-01

    Full Text Available At the 2007 International Communication Association Conference, Web 2.0 was highlighted as an emergent topic of research with a keynote panel entitled 'What's so Significant about Social Networking? Web 2.0 and its Critical Potentials'. One of the thought-provoking moments during the panel was the juxtaposition of two very different and at first, contradictory theoretical approaches to the relationships between Web 2.0 and user-generated content. While Henry Jenkins focused on the democratic potential of online participatory culture as enabling new modes of knowledge production, Titziana Terranova argued for a post-Marxist perspective on Web 2.0 as a site of cultural colonization and expansion of new forms of capitalization on culture, affect and knowledge. The juxtaposition of these two very different critical approaches did not simply rehash the old divide between cultural theory, particularly active audience theory, and post-Marxist critical theory; rather, this debate over Web 2.0 suggested new possibilities for the synthesis and continued development of both sets of critiques. In other words, the event reinforced our belief that corporate colonization arguments do not provide an entirely adequate model for understanding Web 2.0. After all, commercial Web 2.0 spaces such as Facebook, YouTube and MySpace are important sites of cultural exchange and political discussion, in part because they almost entirely rely on user-generated content to exist.

    Pedretti, Erminia G.

    2004-07-01

    Recently, science centers have created issues-based exhibitions as a way of communicating socioscientific subject matter to the public. Research in the last decade has investigated how critical issues-based installations promote more robust views of science, while creating effective learning environments for teaching and learning about science. The focus of this paper is to explore research conducted over a 10-year period that informs our understanding of the nature of learning through these experiences. Two specific exhibitions - Mine Games and A Question of Truth - provide the context for discussing this research. Findings suggest that critical issues-based installations challenge visitors in different ways - intellectually and emotionally. They provide experiences beyond usual phenomenon-based exhibitions and carry the potential to enhance learning by personalizing subject matter, evoking emotion, stimulating dialogue and debate, and promoting reflexivity. Critical issues-based exhibitions serve as excellent environments in which to explore the nature of learning in these nonschool settings.

    2015-12-15

    For almost a century, the cultivation, sale and use of recreational cannabis has been prohibited by law in most countries. Recently, however, under ballot initiatives four states in the US have legalised commercial, non-medical (recreational) cannabis markets. Several other states will initiate similar ballot measures attached to the 2016 election that will also appoint a new President. As the first state to implement the legislation in 2014, Colorado is an important example to begin investigating early consequences of specific policy choices while other jurisdictions consider their own legislation although the empirical evidence base is only beginning to accrue. This paper brings together material sourced from peer reviewed academic papers, grey literature publications, reports in mass media and niche media outlets, and government publications to outline the regulatory model and process in Colorado and to describe some of the issues that have emerged in the first 20 months of its operation. These issues include tension between public health and profit, industry and investment, new methods of consumption, the black market and product testing. The paper concludes that, while it is too early to determine the impact of the scheme, and noting that it includes some features designed to mitigate adverse impacts, it faces major challenges. Not least of these are the lack of an effective overarching federal regulatory structure, as a consequence of the federal prohibition on cannabis, combined with a rapidly growing cannabis industry which, like other industries, will seek to exploit loopholes to maximise profit.

  19. Media Coverage of Alcohol Issues: A Critical Political Economy Framework-A Case Study from Ireland.

    2017-06-16

    There is a growing literature on news media representations of alcohol-related issues. However, current scholarship has neglected critical political economic frameworks to interpret media coverage of alcohol. This paper presents such a framework that conceives of news organisations as corporations that share the values and interests of political and economic elites. The media are thus expected to present viewpoints that are more aligned with the alcohol industry than the scientific consensus on public health policy would warrant. The media are also expected, but to a lesser extent, to present a certain amount of support for public health perspectives because these are supported by a few socioeconomic elite groups (the medical professions, progressive politicians). The case of Ireland from 2012 to 2017 illustrates the framework empirically. Four main newspapers' coverage of the Public Health (Alcohol) Bill and related policies is examined. Results show that, overall, 44.0% of articles support public health measures and 56.0% are opposed or remain neutral. It is argued that the media are not strong proponents of public health for multiple reasons: there are more articles opposed to or neutral toward public health measures than supporting them; the number of supportive articles remains relatively small and there are still many pieces presenting drinks industry views; there are virtually no calls in the media for stronger measures; supportive coverage is partially explained by the pub owners lobby's support for minimum unit pricing; the media often downplay or ignore the negative consequences of alcohol, such as its role in accidents; many news articles normalise drinking and promote events sponsored by the industry; there is not a single Irish journalist covering alcohol issues systematically; and other policy issues that are prioritised by elites receive multiple times more media coverage than public health measures.

  1. Phytosanitary irradiation of fresh tropical commodities in Hawaii: Generic treatments, commercial adoption, and current issues

    International Nuclear Information System (INIS)

    Follett, Peter A.; Weinert, Eric D.

    2012-01-01

    Hawaii is a pioneer in the use of phytosanitary irradiation. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping papaya and other tropical fruits and vegetables to the United States mainland using irradiation for 11 years. Irradiation is an approved treatment to control quarantine pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5500 t). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) will accelerate commodity export approvals and facilitate worldwide adoption. Lowering doses for specific pests and commodities can lower treatment costs and increase capacity owing to shorter treatment times, and will minimize any quality problems. Current impediments to wider adoption include the 1 kGy limit for fresh horticultural products, the labeling requirement, and non-acceptance of phytosanitary irradiation in Japan, the European Union, and elsewhere. Irradiation has potential as a treatment for unregulated imports to prevent new pest incursions. - Highlights: ► Irradiation is used to control quarantine insects in exported fresh commodities. ► Hawaii exported 5.7 t of tropical produce using irradiation in 2010. ► Generic radiation treatments will accelerate commodity export approvals. ► Lowering the dose for specific commodities will reduce costs/maintain quality. ► Current issues include the 1 kGy dose limit and labeling requirements.

    Full Text Available American society faces complex educational issues which impact many facets of its national interests. Institutions of higher education are granting doctoral degrees to educational leaders, but it is not known to what extent their dissertation topics are aligned with both longstanding and critical issues in education. Using a theoretical framework synthesizing Paul and Elder’s critical thinking model and Kuhlthau’s information seeking process, this study examines a set of education doctoral dissertation topical selections and categorizes them by general themes in relationship to many of the recognized educational issues in the United States. Investigators categorized dissertations from four departments within the College of Education of their home institution. The dataset, retrieved from ProQuest Dissertations and Theses Global, consisted of 231 documents published between 2005 and 2014. Through an inter-rater process examining dissertation titles, abstracts, and keywords, the dissertations were assigned critical issue themes culled from nine editions of a college text, and then categorized under a broader topical scheme situated within a well-used educational research website. Findings indicated that most dissertations concentrated in studies that researched problems and issues within schools. Further, some of the issues considered longstanding were not studied by dissertation authors within the sample. For example, privatization of schools and classroom discipline and justice were not selected for study. Findings also suggest new directions for those responsible for dissertation supervision and topic selection. The study adds to the literature on dissertation topic selection that addresses existing educational issues.

    International Nuclear Information System (INIS)

    Parks, C.V.; Broadhead, B.L.

    1995-01-01

    The staff of the Nuclear Engineering Applications Section (NEAS) at Oak Ridge National Laboratory (ORNL) have been involved for over 25 years with the development and application of computational tools for use in analyzing the criticality safety and shielding features of transportation packages carrying radioactive material (RAM). The majority of the computational tools developed by ORNL/NEAS have been included within the SCALE modular code system (SCALE 1995). This code system has been used throughout the world for the evaluation of nuclear facility and package designs. With this development and application experience as a basis, this paper highlights a number of criticality safety and shielding analysis issues that confront the designer and reviewer of a new RAM package. Changes in the types and quantities of material that need to be shipped will keep these issues before the technical community and provide challenges to future package design and certification

    The critical issues, evaluation and comparison of two inertial fusion energy (IFE) reactor design concepts developed in the Prometheus studies are presented. The objectives were (1) to identify and characterize the critical issues and the R and D required to solve them, and (2) to establish a sound basis for future IFE technical and programmatic decisions by evaluating and comparing the different design concepts. Quantitative evaluation and comparison of the two design options have been made with special focus on physics feasibility, engineering feasibility, economics, safety and environment, and research and development (R and D) requirements. Two key conclusions are made based on the overall evaluation analysis: (1) The heavy-ion driven reactors appear to have an overall advantage over laser-driven reactors; and: (2) The differences in scores are not large and future results of R and D could change the overall ranking of the two IFE concepts

    2012-01-01

    For the purpose of developing a consensus method for the reliability assessment of safety-critical digital instrumentation and control systems in nuclear power plants, several high level issues in reliability assessment of the safety-critical software based on Bayesian belief network modeling and statistical testing are discussed. Related to the Bayesian belief network modeling, the relation between the assessment approach and the sources of evidence, the relation between qualitative evidence and quantitative evidence, how to consider qualitative evidence, and the cause-consequence relation are discussed. Related to the statistical testing, the need of the consideration of context-specific software failure probabilities and the inability to perform a huge number of tests in the real world are discussed. The discussions in this paper are expected to provide a common basis for future discussions on the reliability assessment of safety-critical software. (author)

    This report provides a view of anticipated transportation, packaging, and facility handling operations that are expected to occur at mixed-oxide (MOX) fuel fabrication and commercial reactor facilities. This information is intended for use by prospective contractors to the U.S. Department of Energy (DOE) who plan to submit proposals to DOE to manufacture and irradiate MOX fuel assemblies in domestic commercial light-water reactors. The report provides data to prospective consortia regarding packaging and pickup of MOX nuclear fuel assemblies at a MOX fuel manufacturing plant and transport and delivery of the MOX assemblies to nuclear power plants. The report also identifies areas where data are incomplete either because of the status of development or lack of sufficient information and specificity regarding the nuclear power plant(s) where deliveries will take place

    The commercially available finite element code ANSYS has been adapted to solve the critical state of single strips and multifilamentary tapes. We studied a special algorithm which approaches the critical state by an iterative adjustment of the material resistivity. Then, we proved its validity by comparing the results obtained for a thin strip to the Brand theory for the transport current and magnetization cases. Also, the challenging calculation of the magnetization loss of a real multifilamentary BSCCO tape showed the usefulness of our method. Finally, we developed several methods to enhance the speed of convergence, making the proposed process quite competitive in the existing survey of ac losses simulations.

    Two inertial fusion energy (IFE) reactor design concepts developed in the Prometheus studies were evaluated. Objectives were to identify and characterize critical issues and the R and D required to resolve them, and to establish a sound basis for future IFE technical and programmatic decisions. Each critical issue contains several key physics and engineering issues associated with major reactor components and impacts key aspects of feasibility, safety, and economic potential of IFE reactors. Generic critical issues center around: demonstration of moderate gain at low driver energy, feasibility of direct drive targets, feasibility of indirect drive targets for heavy ions, feasibility of indirect drive targets for lasers, cost reduction strategies for heavy ion drivers, demonstration of higher overall laser driver efficiency, tritium self-sufficiency in IFE reactors, cavity clearing at IFE pulse repetition rates, performance/reliability/lifetime of final laser optics, viability of liquid metal film for first wall protection, fabricability/reliability/lifetime of SiC composite structures, validation of radiation shielding requirements, design tools, and nuclear data, reliability and lifetime of laser and heavy ion drivers, demonstration of large-scale non-linear optical laser driver architecture, demonstration of cost effective KrF amplifiers, and demonstration of low cost, high volume target production techniques. Quantitative evaluation and comparison of the two design options have been made with special focus on physics feasibility, engineering feasibility, economics, safety and environment, and research and development (R and D) requirements. Two key conclusions are made based on the overall evaluation analysis. The heavy-ion driven reactors appear to have an overall advantage over laser-driven reactors.

    1997-01-01

    Low power, optoelectronic integrated circuits are being developed for high speed switching and data processing applications. These high performance optoelectronic computing modules consist of three primary components: vertical cavity surface emitting lasers, diffractive optical interconnect elements, and detector/amplifier/laser driver arrays. Following the design and fabrication of an HPOC module prototype, selected commercial funding sources will be evaluated to support a product development stage. These include the formation of a strategic alliance with one or more microprocessor or telecommunications vendors, and/or equity investment from one or more venture capital firms.

    Full Text Available This paper will illustrate the meaning and importance of human resource management (HRM, human resource planning, and strategic human resource management, which are critically important for an organization’s effectiveness and must be effectively managed (Doherty, 1998. This study used the literature review method to acquire its final results. The relevant HRM literature review was done according to the purpose of the study. It used the purposive random sample method for selecting relevant literature. This study shows the current economic environment in the sports industry; the second part of the study critically analyzes the value of the strategic management of employees for the effective and efficient operation of sports organizations. It also critically evaluates human resource planning and other pertinent issues in terms of legislation, recruitment, selection, training, induction, and reward management from different international examples in sports management. Over the past few decades, increasing competition, globalization, and continuous changes in the market and in technology have emphasized the need to rethink the management of the organization and of human resources for the sake of overcoming significant challenges (Taylor et al., 2006. Therefore, managers should use strategic human resource management to overcome significant issues and to form well-planned strategies so that the organization may succeed.

    1997-04-01

    On January 14, 1997, the Department of Energy, as part of its Record of Decision on the storage and disposition of surplus nuclear weapons materials, committed to pursue the use of excess weapons-usable plutonium in the fabrication of mixed-oxide (MOX) fuel for consumption in existing commercial nuclear power plants. Domestic use of MOX fuel has been deferred since the late 1970s, principally due to nuclear proliferation concerns. This report documents a review of past and present literature (i.e., correspondence, reports, etc.) on the domestic use of MOX fuel and provides discussion on the technical and regulatory issues that must be addressed by DOE (and the utility/consortia selected by DOE to effect the MOX fuel consumption strategy) in obtaining approval from the Nuclear Regulatory Commission to use MOX fuel in one or a group of existing commercial nuclear power plants

    Full Text Available Two-thirds of the world′s population with low vision resides in the Asia-Pacific region. Provision of comprehensive low vision services is important to improve vision-related quality of life (QoL for people with this condition. This review outlines the critical issues and challenges facing the provision of low vision services in the Asia-Pacific region. The review offers possible strategies to tackle these issues and challenges facing service providers and policy makers in lieu of Vision 2020 strategies in this area. Pertinent findings from the global survey of low vision services and extensive ground work conducted in the region are used; in addition, a discussion on the availability of services, human resources and training, and funding and the future sustainability of low vision care will be covered. In summary, current issues and challenges facing the region are the lack of specific evidence-based data, access, appropriate equipment and facilities, human resources, funding, and sustainability. These issues are inextricably interlinked and thus cannot be addressed in isolation. The solutions proposed cover all areas of the VISION 2020 strategy that include service delivery, human resources, infrastructure and equipment, advocacy and partnership; and include provision of comprehensive care via vertical and horizontal integration; strengthening primary level care in the community; providing formal and informal training to enable task shifting and capacity building; and promoting strong government and private sector partnership to achieve long-term service financial sustainability.

    The world is facing complex environmental challenges and a changing climate is one of the most pressing. These challenges require innovative solutions, which can only be achieved by first developing a more science and environmentally literate public through high-quality education. We know a lot about how to frame climate change messages to be most effective for adults (1). However, we know much less about how youth respond to these same messages. It is important to engage adolescents in these conversations, as this is the age when kids begin to think more critically and abstractly about complex problems, but also when peer and social influences increase in importance (2). Thus, middle school is a critical point in young students' lives when they might either lose interest in science or gain a strong science identity. To keep them interested and invested in science and environmental issues, we need relevant and transformative climate change materials for use in the classroom—materials that are video-based, compelling, and presented by other youth. The California Academy of Sciences has developed a video-based series with lessons supporting the NGSS called Flipside Science that challenges youth to think critically about complex environmental issues. Exploring Energy: Designing a Brighter Future is a unit within this series that engages youth in thinking about how we can make changes to our current energy uses and behaviors to combat climate change. The videos in the unit are hosted by diverse teens who bring an optimistic and relevant voice to these issues, and the associated lessons engage students in honing their design thinking and problem-solving skills. Although intended for use inside the classroom, these resources inspire action among youth outside of the classroom and in their communities. Initial evaluations of two other Flipside Science units on water and food issues indicate that the youth-powered nature of the videos and the real-world challenges posed

  11. "New linguistic issues", by Pier Pasolini, is causing scandal among linguists, philologists, writers, critics and intellectuals

    Directory of Open Access Journals (Sweden)

    Teodoro Negri

    1993-12-01

    Full Text Available Pasolini departs from the diagnosis of a problem: the critical quest stage in contemporary literature, centered on the 1950s; he points out the author´s inability to create the design for a national language. He goes on to analyze the deep mutation in Italian Society, which determineted a new socio-linguistic outlook; to wit, a language clearly marked by strong technicality and instrumentation. Drawing examples from newspapers, TV features, official political speeches and commercials, Pasolini demonstrates that factual communication takes precedence over formal expression. This is ascribed to one principle which sets both rules and approvals for all forms of national language. This fact, according to Pasolini, is the result of an industrial and technological transformation process, which would  permite advent of a new linguistic bourgeoisie. The linguistic unification caused by such approving  principle would, therefore, imply the social manifestation of the bourgeoisie.

  12. Phytosanitary irradiation for export of fresh produce. Commercial adoption in Hawaii and current issues

    Follett, P.A.; Wall, M.M.

    2013-01-01

    Hawaii is a pioneer in the use of phytosanitary irradiation. Irradiation is an approved treatment to control quarantine insect pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping tropical fruits and vegetables to the US mainland using irradiation since 2000. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5,500 tonnes). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) has accelerated commodity export approvals and facilitated adoption by foreign trading partners. Current impediments to wider adoption include the labeling requirement, the 1 kGy limit for fresh horticultural products, and non-acceptance of phytosanitary irradiation in Japan and the European Union. USDA Animal and Plant Health Inspection Service (APHIS) has restricted the use of modified atmosphere packaging (MAP) for irradiated fresh fruits exported to the US due to possible increased radio-tolerance in the target insects. Data are presented for response of melon fly in papaya to several types of MAP with radiation treatment at 45-65 Gy. Low oxygen atmospheres can increase insect radio-tolerance, but the effect is dependent on oxygen concentration and radiation dose. (author)

  13. A Social Audit Model for Agro-biotechnology Initiatives in Developing Countries: Accounting for Ethical, Social, Cultural, and Commercialization Issues

    Directory of Open Access Journals (Sweden)

    Obidimma Ezezika

    2009-10-01

    Full Text Available There is skepticism and resistance to innovations associated with agro-biotechnology projects, leading to the possibility of failure. The source of the skepticism is complex, but partly traceable to how local communities view genetically engineered crops, public perception on the technology’s implications, and views on the role of the private sector in public health and agriculture, especially in the developing world. We posit that a governance and management model in which ethical, social, cultural, and commercialization issues are accounted for and addressed is important in mitigating risk of project failure and improving the appropriate adoption of agro-biotechnology in sub-Saharan Africa. We introduce a social audit model, which we term Ethical, Social, Cultural and Commercialization (ESC2 auditing and which we developed based on feedback from a number of stakeholders. We lay the foundation for its importance in agro-biotechnology development projects and show how the model can be applied to projects run by Public Private Partnerships. We argue that the implementation of the audit model can help to build public trust through facilitating project accountability and transparency. The model also provides evidence on how ESC2 issues are perceived by various stakeholders, which enables project managers to effectively monitor and improve project performance. Although this model was specifically designed for agro-biotechnology initiatives, we show how it can also be applied to other development projects.

  14. Argumentation, critical thinking, nature of science and socioscientific issues: a dialogue between two researchers

    Science.gov (United States)

    Yacoubian, Hagop A.; Khishfe, Rola

    2018-05-01

    The purpose of this paper is to compare and contrast between two theoretical frameworks for addressing nature of science (NOS) and socioscientific issues (SSI) in school science. These frameworks are critical thinking (CT) and argumentation (AR). For the past years, the first and second authors of this paper have pursued research in this area using CT and AR as theoretical frameworks, respectively. Yacoubian argues that future citizens need to develop a critical mindset as they are guided to (1) practice making judgments on what views of NOS to acquire and (2) practice making decisions on SSI through applying their NOS understandings. Khishfe asserts that AR is an important component of decision making when dealing with SSI and the practice in AR in relation to controversial issues is needed for informed decision making. She argues that AR as a framework may assist in the development of more informed understandings of NOS. In this paper, the authors delve into a dialogue for (1) elucidating strengths and potential of each framework, (2) highlighting challenges that they face in their research using the frameworks in question, (3) exploring the extent to which the frameworks can overlap, and (4) proposing directions for future research.

    2014-04-01

    Speech errors associated with cleft palate are well established for English and several other Indo-European languages. Few articles describing the speech of Putonghua (standard Mandarin Chinese) speakers with cleft palate have been published in English language journals. Although methodological guidelines have been published for the perceptual speech evaluation of individuals with cleft palate, there has been no critical review of methodological issues in studies of Putonghua speakers with cleft palate. A literature search was conducted to identify relevant studies published over the past 30 years in Chinese language journals. Only studies incorporating perceptual analysis of speech were included. Thirty-seven articles which met inclusion criteria were analyzed and coded on a number of methodological variables. Reliability was established by having all variables recoded for all studies. This critical review identified many methodological issues. These design flaws make it difficult to draw reliable conclusions about characteristic speech errors in this group of speakers. Specific recommendations are made to improve the reliability and validity of future studies, as well to facilitate cross-center comparisons.

    2012-03-01

    Full Text Available The debate about the possibilities to engineer the Earth's climate has changed drastically in the last years. Suggestions of large-scale technological interventions to combat climate change that a decade ago would have been discarded as science fiction are slowly moving into the center of international climate change discussions, research, and politics. In this article, I elaborate three joint key challenges to geo-engineering research from a resilience perspective, with a special emphasis on governance issues. First, I discuss the need to understand geo-engineering proposals from a "planetary boundaries" perspective. Second, I elaborate why the notion of Earth stewardship and geo-engineering are not necessarily in conflict, but instead could be viewed as complementary approaches. Last, I discuss the critical need to explore an institutional setting that is strong enough to weed out geo-engineering proposals that carry considerable ecological risk, but still allow for novelty, fail-safe experimentation, and continuous learning. These issues are critical for our understanding of how to effectively govern global environmental risks, complex systems, and emerging technologies in the Anthropocene.

    Bukowski, Josh H; Richards, John R

    2016-01-01

    As the prevalence of air travel increases, in-flight medical emergencies occur more frequently. A significant percentage of these emergencies occur when there is no certified physician, nurse, or paramedic onboard. During these situations, flight crews might enlist the help of noncertified passengers, such as medical students, dentists, or emergency medical technicians in training. Although Good Samaritan laws exist, many health care providers are unfamiliar with the limited legal protections and resources provided to them after responding to an in-flight emergency. A 78-year-old woman lost consciousness and became pulseless onboard a commercial aircraft. No physician was available. A medical student responded and coordinated care with the flight crew, ground support physician, and other passengers. After receiving a packet (4 g) of sublingual sucrose and 1 L i.v. crystalloid, the patient regained pulses and consciousness. The medical student made the decision not to divert the aircraft based on the patient's initial response to therapy and, 45 min later, the patient had normal vital signs. Upon landing, she was met and taken by paramedics to the nearest emergency department for evaluation of her collapse. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians are the most qualified to assist in-flight emergencies, but they might not be aware of the medicolegal risks involved with in-flight care, the resources available, and the role of the flight crew in liability and decision making. This case, which involved a medical student who was not given explicit protection under Good Samaritan laws, illustrates the authority of the flight crew during these events and highlights areas of uncertainty in the legislation for volunteer medical professionals.

    2000-09-01

    This research forms part of a larger interdisciplinary research project on the termination of pregnancies. The focus of this part of the project is on the ethical issues related to termination of pregnancies. The practice of the professional nurse is confronted with ethical dilemmas and disputes. Whether the nurse chooses to participate in the termination of pregnancies or not, the core function of the nurse is that of counseling and ethical decision-making. Effective counseling requires empathy, respect for human rights and unconditional acceptance of a person. Making ethical decisions implies making critical decisions. It is self-evident, therefore, that such decisions should be based on sound arguments and logical reasoning. It is of vital importance that ethical decisions can be justified on rational ground. Decision-making is a critical thinking approach process for choosing the best action to meet a desired goal. The research question that is relevant for this paper is: Are nurses thinking critically about ethical issues like the termination of pregnancies? To answer the research question a qualitative, exploratory, descriptive design was used (Mouton, 1996:103-169). Registered nurses were selected purposively (Creswell, 1994:15). 1200 registered nurses completed the open-ended questionnaires. Focus group interviews were conducted with 22 registered nurses from a public hospital for women and child health services. Data analysis, using secondary data from open-ended questionnaires and transcribed focus group interviews, were based on the approach of Morse and Field (1994:25-34) and Strauss and Corbin (1990). The themes and categories from open coding were compared, conceptualized and linked with theories on critical thinking (Paul, 1994; Watson & Glaser, 1991 and the American Philosophical Association, 1990). The measures of Lincoln and Guba (1985) and Morse (1994) related to secondary data analysis were employed to ensure trustworthiness. Based on these

    1991-01-01

    In accordance with the Low-Level Radioactive Waste Policy Amendments Act of 1985, States will become responsible for managing low-level radioactive waste, including mixed waste, generated within their borders as of January 1, 1993. In response to this mandate, many States and compact regions have made substantial progress toward establishing new disposal capacity for these wastes. While this progress is noteworthy, many circumstances can adversely affect States' abilities to meet the 1993 deadline, and many States have indicated that they are considering other waste management options in order to fulfill their responsibilities beyond 1992. Among the options that States are considering for the interim management of low- level radioactive waste is temporary storage. Temporary storage may be either short term or long term and may be at a centralized temporary storage facility provided by the State or a contractor, or may be at the point of generation or collection. Whether States choose to establish a centralized temporary storage facility or choose to rely on generators or brokers to provide additional and problem areas that must be addressed and resolved. Areas with many potential issues associated with the temporary storage of waste include: regulations, legislation, and policy and implementation guidance; economics; public participation; siting, design, and construction; operations; and closure and decommissioning

    Superconducting critical-current densities Jsub(c) in fields up to 24 T and at 4.2 and 1.8 K were measured for a number of commercial Nb 3 Sn wires which were alloyed with Ti. The best values of Jsub(c) at 20 T and at 4.2 and 1.8 K were 78 and 156 A mm -2 , respectively. In order to achieve these high current densities at H>20 T, it was shown that nonuniformity of the filaments had to be minimized. It was also shown that the grain size of Nb 3 Sn is not very important in determining Jsub(c) at these high magnetic fields, and that achieving high values of critical magnetic field Hsub(c2) is more important than small grain size.

    Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its wider commercial applicability. Recent advancements in bio-hydrometallurgy have suggested that these critical issues can be successfully alleviated through the addition of a catalyst. The catalyzing properties of a variety of metals ions (Ag + , Hg ++ , Bi +++ , Cu ++ , Co ++ etc.) during bioleaching have been successfully demonstrated. In this article, the role and mechanisms of these metal species in catalyzing bioleaching from different minerals (chalcopyrite, complex sulfides, etc.) and waste materials (spent batteries) are reviewed, techno-economic and environmental challenges associated with the use of metals ions as catalysts are identified, and future prospectives are discussed. Based on the analysis, it is suggested that metal ion-catalyzed bioleaching will play a key role in the development of future industrial bio-hydrometallurgical processes.

    Objectives To assess critical incident exposure among prehospital emergency services personnel in the developing world context of South Africa; and to assess associated mental health consequences. Methods We recruited a representative sample from emergency services in the Western Cape Province, South Africa, to participate in this cross sectional epidemiological study. Questionnaires covered critical incident exposure, general psychopathology, risky alcohol use, symptoms of post‐traumatic stress disorder (PTSD), and psychological and physical aggression between co‐workers. Open ended questions addressed additional stressors. Results Critical incident exposure and rates of general psychopathology were higher than in studies in the developed world. Exposure to critical incidents was associated with general psychopathology, symptoms of PTSD, and with aggression between co‐workers, but not with alcohol use. Ambulance, fire, and sea rescue services had lower general psychopathology scores than traffic police. The sea rescue service also scored lower than traffic police on PTSD and psychological aggression. The defence force had higher rates of exposure to physical assault, and in ambulance services, younger staff were more vulnerable to assault. Women had higher rates of general psychopathology and of exposure to psychological aggression. Other stressors identified included death notification, working conditions, and organisational problems. Conclusions Service organisations should be alert to the possibility that their personnel are experiencing work ‐related mental health and behavioural problems, and should provide appropriate support. Attention should also be given to organisational issues that may add to the stress of incidents. Workplace programmes should support vulnerable groups, and address death notification and appropriate expression of anger. PMID:16498167

    Most action to address contemporary complex challenges, including the urgent issues of global sustainability, occurs piecemeal and without meaningful guidance from leading complex change knowledge and methods. The potential benefit of using such knowledge is greater efficacy of effort and investment. However, this knowledge and its associated tools and methods are under-utilized because understanding about them is low, fragmented between diverse knowledge traditions, and often requires shifts in mindsets and skills from expert-led to participant-based action. We have been engaged in diverse action-oriented research efforts in Large System Change for sustainability. For us, "large" systems can be characterized as large-scale systems - up to global - with many components, of many kinds (physical, biological, institutional, cultural/conceptual), operating at multiple levels, driven by multiple forces, and presenting major challenges for people involved. We see change of such systems as complex challenges, in contrast with simple or complicated problems, or chaotic situations. In other words, issues and sub-systems have unclear boundaries, interact with each other, and are often contradictory; dynamics are non-linear; issues are not "controllable", and "solutions" are "emergent" and often paradoxical. Since choices are opportunity-, power- and value-driven, these social, institutional and cultural factors need to be made explicit in any actionable theory of change. Our emerging network is sharing and building a knowledge base of experience, heuristics, and theories of change from multiple disciplines and practice domains. We will present our views on focal issues for the development of the field of large system change, which include processes of goal-setting and alignment; leverage of systemic transitions and transformation; and the role of choice in influencing critical change processes, when only some sub-systems or levels of the system behave in purposeful ways

    Full Text Available National Health Insurance (NHI in Korea has covered Korean medicine (KM services including acupuncture, moxibustion, cupping, and herbal preparations since 1987, which represents the first time that an entire traditional medicine system was insured by an NHI scheme anywhere in the world. This nationwide insurance coverage led to a rapid increase in the use of KM, and the KM community became one of the main interest groups in the Korean healthcare system. However, due to the public's safety concern of and the stagnancy in demand for KM services, KM has been facing new challenges. This paper presents a brief history and the current structure of KM health insurance, and describes the critical issues related to KM insurance for in-depth understanding of the present situation.

    A team from the Universities of Wisconsin, Washington, and Illinois performed an engineering scoping study of critical issues for field-reversed configuration (FRC) power plants. The key tasks for this research were (1) systems analysis for deuterium-tritium (D-T) FRC fusion power plants, and (2) conceptual design of the blanket and shield module for an FRC fusion core. For the engineering conceptual design of the fusion core, the project team focused on intermediate-term technology. For example, one decision was to use steele structure. The FRC systems analysis led to a fusion power plant with attractive features including modest size, cylindrical symmetry, good thermal efficiency (52%), relatively easy maintenance, and a high ratio of electric power to fusion core mass, indicating that it would have favorable economics.

  8. Crossing alone the Mediterranean sea. Some critical issues about unaccompanied minors in Europe

    Directory of Open Access Journals (Sweden)

    Giovanni Giulio Valtolina

    Full Text Available Abstract Despite the increasing social impact of unaccompanied migrant minors (UAMs in many European Union (EU member states, EU regulations on UAMs are still inadequate and the necessary protection measures are thus insufficient. More specifically, the “best interest of the child”, stated in a large number of international documents, may not be properly guaranteed. In addition, there is often a discrepancy between the rights of migrant children, according to the international legislation, and the actual protection they receive. Moreover, despite the declared aim of reaching a common standard of reception and inclusion, policies and practices across Europe are still very different. The paper attempts to highlight and discuss some critical issues regarding UAMs in Europe. Over and beyond the need for the EU to develop a common framework, greater efforts should be made in order to improve inclusion of UAMs, especially to ensure the management of the phenomenon beyond the current emergency.

    Survivors of critical illness commonly experience neuromuscular abnormalities, including muscle weakness known as ICU-acquired weakness (ICU-AW). ICU-AW is associated with delayed weaning from mechanical ventilation, extended ICU and hospital stays, more healthcare-related hospital costs, a higher risk of death, and impaired physical functioning and quality of life in the months after ICU admission. These observations speak to the importance of developing new strategies to aid in the physical recovery of acute respiratory failure patients. We posit that to maintain optimal muscle mass, strength and physical function, the combination of nutrition and exercise may have the greatest impact on physical recovery of survivors of critical illness. Randomized trials testing this and related hypotheses are needed. We discussed key methodological issues and proposed a common evaluation framework to stimulate work in this area and standardize our approach to outcome assessments across future studies.

  11. Regulatory compliance issues related to the White Oak Creek Embayment time-critical removal action

    International Nuclear Information System (INIS)

    Leslie, M.; Kimmel, B.L.

    1992-01-01

    In September 1990, Martin Marietta Energy Systems (Energy Systems) discovered high levels of Cesium-137 present in surface sediments at the mouth of White Oak Creek (WOC) Embayment. WOC receives the majority of surface water drainage from Oak Ridge National Laboratory. Following this discovery, the Department of Energy (DOE) and Energy Systems pursued stabilizing sediment migration under provisions of the National Contingency Plan (NCP) Section 300.400 et. seq. as a time-critical removal action. However, significant uncertainty exists concerning the applicability of NCP procedural requirements designed for conducting US EPA-led, Superfund-financed response actions, because NCP Subpart K dealing with response actions at federal facilities has not been promulgated. In addition, relatively new guidance exists from DOE concerning National Environmental Policy Act documentation requirements for categorical exclusions associated with conducting removal actions at DOE facilities. A proactive approach was taken to identify issues and involve appropriate state and federal regulatory agencies. This approach required achieving consensus among all involved parties and identification of all applicable or relevant and appropriate regulatory requirements related to the removal action. As a result, this project forms a framework for conducting future time-critical removal actions at federal facilities

    Themelis, J.G.; Krishnan, K.R.

    1985-01-01

    The Uranium Mill Tailings Radiation Control Act of 1978 (PL95-604) authorized the Secretary of Energy to enter into cooperative agreements with certain states and Indian Tribes to clean up 24 inactive uranium mill tailing sites and associated vicinity properties. The Uranium Mill Tailings Remedial Action (UMTRA) Project includes the three Federal agencies (EPA, DOE, and NRC), eleven state, Indian Tribes, and at least four major contractors. The UMTRA Project extends over a period of ten years. The standards for the Project require a design life of 1000 years with a minimum performance period of 200 years. This paper discusses the critical management issues in dealing with the UMTRA Project and identifies the development of solutions for many of those issues. The highlights to date are promulgation of EPA standards, continued support from Congress and participating states and Indian Tribes, significant leadership shown at all levels, establishment of credibility with the public, and continued motivation of the team. The challenge for tomorrow is making certain NRC will license the sites and maintaining the high level of coordination exhibited to date to assure Project completion on schedule

  13. References to Human Rights in Codes of Ethics for Psychologists: Critical Issues and Recommendations. Part 1

    Directory of Open Access Journals (Sweden)

    Жанель Готье

    2018-12-01

    Full Text Available There are codes of ethics in psychology that explicitly refer to human rights. There are also psychologists interested in the protection and promotion of human rights who are calling for the explicit inclusion of references to human rights in all psychology ethics codes. Yet, references to human rights in ethics documents have rarely been the focus of attention in psychological ethics. This article represents the first part of a two-part article series focusing on critical issues associated with the inclusion of references to human rights in the ethical codes of psychologists, and recommendations about how psychological ethics and the human rights movement can work together in serving humanity. The first part of the article series examines issues pertaining to the interpretation of references to human rights in codes of ethics for psychologists, and the justifications for including these references in psychological ethics codes. The second part of the article series examines how the Universal Declaration of Ethical Principles for Psychologists can be used to extend or supplement codes of ethics in psychology, how ethical principles and human rights differ and complement each other, and how psychological ethics and the human rights movement can work together in serving humanity and improving the welfare of both persons and peoples.

    Woodrow, Sarah I; Gilmer-Hill, Holly; Rutka, James T

    2006-10-01

    The role of women in Western society has changed dramatically in the past several decades. Despite this, many gender disparities still exist for professionals in the health care sector. In neurosurgery, a disproportionately small percentage of the workforce in the United States and Canada is female. These figures are lower than most reported in other medical specialties. This review critically examines factors that may be influencing women's ability to advance in demanding subspecialties such as neurosurgery. The literature on women in medicine, and surgery in particular, were reviewed to identify different issues facing women currently in practice in neurosurgery. In addition, the concerns of prospective trainees were examined. There remain many challenges for women entering neurosurgery, including unique lifestyle concerns, limited mentorship, out-dated career programs, and deep-seeded societal beliefs. Discrimination and harassment are also contributing factors. If neurosurgery is to continue to progress as a subspecialty, the issue of gender inequality needs to be scrutinized more closely. Innovative programs must be developed to meet the needs of current female faculty members and to ensure attracting the brightest individuals of both genders into a career in neurosurgery.

  15. An Analysis for the Use of Research and Education Networks and Commercial Network Vendors in Support of Space Based Mission Critical and Non-Critical Networking

    Bradford, Robert N.

    2002-01-01

    Currently, and in the past, dedicated communication circuits and "network services" with very stringent performance requirements are being used to support manned and unmanned mission critical ground operations at GSFC, JSC, MSFC, KSC and other NASA facilities. Because of the evolution of network technology, it is time to investigate using other approaches to providing mission services for space ground operations. The current NASA approach is not in keeping with the evolution of network technologies. In the past decade various research and education networks dedicated to scientific and educational endeavors have emerged, as well as commercial networking providers, that employ advanced networking technologies. These technologies have significantly changed networking in recent years. Significant advances in network routing techniques, various topologies and equipment have made commercial networks very stable and virtually error free. Advances in Dense Wave Division Multiplexing will provide tremendous amounts of bandwidth for the future. The question is: Do these networks, which are controlled and managed centrally, provide a level of service that equals the stringent NASA performance requirements. If they do, what are the implication(s) of using them for critical space based ground operations as they are, without adding high cost contractual performance requirements? A second question is the feasibility of applying the emerging grid technology in space operations. Is it feasible to develop a Space Operations Grid and/or a Space Science Grid? Since these network's connectivity is substantial, both nationally and internationally, development of these sorts of grids may be feasible. The concept of research and education networks has evolved to the international community as well. Currently there are international RENs connecting the US in Chicago to and from Europe, South America, Asia and the Pacific rim, Russia and Canada. And most countries in these areas have their

  17. The critical issue of nuclear power plant safety in developing countries

    International Nuclear Information System (INIS)

    Rosen, M.

    1977-01-01

    A little more than a decade from now, large commercial nuclear power facilities will be in operation in almost 40 countries, of which approximately one-half are presently considered industrially less developed. Ambitious nuclear programmes coupled with minimal and frequently under-staffed regulatory and utility organizations are only one aspect of the difficulties related to the safety of nuclear plants that face these developing countries. Inherent problems of meeting current safety standards and requirements for the significantly non-standard nuclear power plant exports can be compounded by financial considerations that may lead to purchases of reactors of various types, from more than one supplier country and with different safety standards and requirements. An examination of these issues points to the necessity and opportunity for effective action which could include provision for adequate funding for safety considerations in the purchase contract, and for sufficient regulatory assistance and training from the developed countries. The article will introduce the topic, discuss specific examples, and offer some suggestions. (author)

    This research aimed to investigate the changes in ethical issues in everyday clinical practice recognized by critical care nurses during two observation periods. We conducted a retrospective analysis of data obtained by prospective questionnaire surveys of nurses in the intensive care units (ICU) of a tertiary university-affiliated hospital in Seoul, Korea. Data were collected prospectively during two different periods, February 2002-January 2003 (Period 1) and August 2011-July 2012 (Period 2). Significantly fewer cases with ethical issues were reported in Period 2 than in Period 1 (89 cases [2.1%] of 4,291 ICU admissions vs. 51 [0.5%] of 9,302 ICU admissions, respectively; P ethical issues in both Periods occurred in MICU. The major source of ethical issues in Periods 1 and 2 was behavior-related. Among behaviorrelated issues, inappropriate healthcare professional behavior was predominant in both periods and mainly involved resident physicians. Ethical issue numbers regarding end-oflife (EOL) care significantly decreased in the proportion with respect to ethical issues during Period 2 (P = 0.044). In conclusion, the decreased incidence of cases with identified ethical issues in Period 2 might be associated with ethical enhancement related with EOL and improvements in the ICU care environment of the studied hospital. However, behaviorrelated issues involving resident physicians represent a considerable proportion of ethical issues encountered by critical care nurses. A systemic approach to solve behavior-related issues of resident physicians seems to be required to enhance an ethical environment in the studied ICU.

  19. Is Model-Based Development a Favorable Approach for Complex and Safety-Critical Computer Systems on Commercial Aircraft?

    Torres-Pomales, Wilfredo

    2014-01-01

    A system is safety-critical if its failure can endanger human life or cause significant damage to property or the environment. State-of-the-art computer systems on commercial aircraft are highly complex, software-intensive, functionally integrated, and network-centric systems of systems. Ensuring that such systems are safe and comply with existing safety regulations is costly and time-consuming as the level of rigor in the development process, especially the validation and verification activities, is determined by considerations of system complexity and safety criticality. A significant degree of care and deep insight into the operational principles of these systems is required to ensure adequate coverage of all design implications relevant to system safety. Model-based development methodologies, methods, tools, and techniques facilitate collaboration and enable the use of common design artifacts among groups dealing with different aspects of the development of a system. This paper examines the application of model-based development to complex and safety-critical aircraft computer systems. Benefits and detriments are identified and an overall assessment of the approach is given.

    2016-01-01

    Scaling relations describing the electromagnetic behaviour of coated conductors (CCs) greatly simplify the design of REBCO-based devices. The performance of REBCO CCs is strongly influenced by fabrication route, conductor architecture and materials, and these parameters vary from one manufacturer to the others. In the present work we have examined the critical surface for the current density, Jc(T,B,θ ), of coated conductors from six different manufacturers: American Superconductor Co. (US), Bruker HTS GmbH (Germany), Fujikura Ltd. (Japan), SuNAM Co. Ltd. (Korea), SuperOx ZAO (Russia) and SuperPower Inc. (US). Electrical transport and magnetic measurements were performed at temperatures between 4.2 K and 77 K and in magnetic field up to 19 T. Experiments were conducted at three different orientations of the field with respect to the crystallographic c-axis of the REBCO layer, θ = 0deg , 45deg and 90deg , in order to probe the angular anisotropy of Jc. In spite of the large variability of CCs performance, ...

    Bloch, Jean-François; Tardieu-Guigues, Elisabeth

    2014-10-01

    The sea will be a source of economic development in the next years. Today the research works in marine biotechnologies supply new products and processes. The introduction in the laboratories of a new technology, synthesis biology, is going to increase the possibilities of creation of new products. Exploitation of product stemming from marine biodiversity has to be made with regard to various rights among which industrial property law, maritime law and the Convention on BioDiversity. All participants involved in the promotion of research in marine biotechnology must address the fair and equitable sharing of any commercial exploitation. Carrying out work involving synthetic biology has increased the number of unanswered questions about how operators should manage in order to avoid any threat of being sued for infringements of IP rights or for alleged bio-piracy. This paper, by no means exhaustive in the field, analyzes some of the issues raised on the modification to the landscape in marine biotechnology by the advent of synthetic biology. Such issues indicate how important the collaboration between researchers, industrialists, lawyers is for allowing proper use of marine biotech. Copyright © 2014 Elsevier B.V. All rights reserved.

    The World Health Organisation has advocated for comprehensive primary care teams, which include family physicians. However, despite (or because of) severe doctor shortages in Africa, there is insufficient clarity on the role of the family physician in the primary health care team. Instead there is a trend towards task shifting without thought for teamwork, which runs the risk of dangerous oversimplification. It is not clear how African leaders understand the challenges of implementing family medicine, especially in human resource terms. This study, therefore, sought to explore the views of academic and government leaders on critical human resource issues for implementation of family medicine in Africa. In this qualitative study, key academic and government leaders were purposively selected from sixteen African countries. In-depth interviews were conducted using an interview guide. All interviews were audio-recorded, transcribed and thematically analysed. There were 27 interviews conducted with 16 government and 11 academic leaders in nine Sub-Saharan African countries: Botswana, Democratic Republic of Congo, Ghana, Kenya, Malawi, Nigeria, Rwanda, South Africa and Uganda. Respondents spoke about: educating doctors in family medicine suited to Africa, including procedural skills and holistic care, to address the difficulty of recruiting and retaining doctors in rural and underserved areas; planning for primary health care teams, including family physicians; new supervisory models in primary health care; and general human resource management issues. Important milestones in African health care fail to specifically address the human resource issues of integrated primary health care teamwork that includes family physicians. Leaders interviewed in this study, however, proposed organising the district health system with a strong embrace of family medicine in Africa, especially with regard to providing clinical leadership in team-based primary health care. Whilst these

    California electric utilities have been exploring the use of dynamic critical peak prices (CPP) and other demand response programs to help reduce peaks in customer electric loads. CPP is a tariff design to promote demand response. Levels of automation in DR can be defined as follows: Manual Demand Response involves a potentially labor-intensive approach such as manually turning off or changing comfort set points at each equipment switch or controller. Semi-Automated Demand Response involves a pre-programmed demand response strategy initiated by a person via centralized control system. Fully Automated Demand Response does not involve human intervention, but is initiated at a home, building, or facility through receipt of an external communications signal. The receipt of the external signal initiates pre-programmed demand response strategies. They refer to this as Auto-DR. This paper describes the development, testing, and results from automated CPP (Auto-CPP) as part of a utility project in California. The paper presents the project description and test methodology. This is followed by a discussion of Auto-DR strategies used in the field test buildings. They present a sample Auto-CPP load shape case study, and a selection of the Auto-CPP response data from September 29, 2005. If all twelve sites reached their maximum saving simultaneously, a total of approximately 2 MW of DR is available from these twelve sites that represent about two million ft{sup 2}. The average DR was about half that value, at about 1 MW. These savings translate to about 0.5 to 1.0 W/ft{sup 2} of demand reduction. They are continuing field demonstrations and economic evaluations to pursue increasing penetrations of automated DR that has demonstrated ability to provide a valuable DR resource for California.

    2013-12-01

    In the spring of 2014 Washington University will present one of the first courses, entitled 'Critical Earth Issues,' in a new experiment in online education to be carried out by a consortium of Universities working with the production company 2U. The consortium, consisting of Washington University in St. Louis, Boston College, Brandeis University, Emory University, Northwestern University, the University of North Carolina at Chapel Hill, and the University of Notre Dame, will all offer courses that can be taken by each other's students. In addition, three affiliate institutions so far (Baylor University, Southern Methodist University, and Temple University) have agree to allow their students to take online courses from this consortium, and transfer credit will be granted from the consortium institution teaching a particular course to students from other institutions as well. A total of eleven courses from the seven consortium schools are being taught in the fall of 2013. 'Critical Earth Issues,' to be taught the next spring, will be the first geoscience course taught. The structure of the course will be very different from traditional MOOCs. Half of the course (80 minutes per week) will be asynchronous and produced in advance by the company 2U. This is designed to take the place of the lecture component of a class, but it can take a variety of forms. While there are traditional lecture segments and filmed demos, these are also broken up by assignments for the students in order to make the 'lecture' segment more interactive. Sometimes the students will have to answer short or long questions before they can go on to the next part of the asynchronous material. Students can only get to the assignment at the end if they work their way through all the produced and interactive segments. This material will often also prompt them to upload an 'assignment,' such as uploading photos of different rocks that are used for the buildings at their host institution (to be shared

  5. Critical scientific issues in the demonstration of WIPP compliance with EPA repository standards

    International Nuclear Information System (INIS)

    Weart, W.D.; Chu, M.S.Y.

    1997-01-01

    The Department of Energy submitted a Compliance Certification Application for the Waste Isolation Pilot Plant to the Environmental Protection Agency (EPA) in October, 1996. A critical part of this application was a Performance Assessment which predicts the cumulative radioactive release to the accessible environment over a time period of 10,000 years. Comparison of this predicted release to the EPA standard shows a comfortable margin of compliance. The scientific understanding that was critical to developing this assessment spans a broad range of geotechnical disciplines, and required a thorough understanding of the site's geology and hydrology. Evaluation of the geologic processes which are active in the site region establishes that there will be no natural breach of site integrity for millions of years, far longer than the 10,000 year regulatory period. Inadvertent human intrusion is, therefore, the only credible scenario to lead to potential radioactive release to the accessible environment. To substantiate this conclusion and to quantify these potential releases from human intrusion, it has been necessary to develop an understanding of the following processes: (1) salt creep and shaft seal efficacy; (2) gas generation from organic decomposition of waste materials and anoxic corrosion of metals in the waste and waste packages; (3) solubilities for actinides in brine; (4) fluid flow in Salado formation rocks, and (5) hydrologic transport of actinides in the overlying dolomite aquifers. Other issues which had to be evaluated to allow definition of breach scenarios were brine reservoir occurrences and their associated reservoir parameters, consequences of mining over the repository, and drilling for natural resources in the vicinity of the repository. Results of all these studies will be briefly summarized in this paper

    Domestic abuse is increasingly recognised as a serious, worldwide public health concern. There is a significant body of literature regarding domestic abuse, but little is known about health professionals' beliefs about domestic abuse disclosure. In addition, the intersection between health professionals' beliefs and abused women's views remains uninvestigated. We report on a two-phase, qualitative study using Critical Incident Technique (CIT) that aimed to explore community health professionals' beliefs about domestic abuse and the issue of disclosure. We investigated this from the perspectives of both health professionals and abused women. The study took place in Scotland during 2011. The study was informed theoretically by the Common Sense Model of Self-Regulation of Health and Illness (CSM). This model is typically used in disease-orientated research. In our innovative use, however, CSM was used to study the social phenomenon, domestic abuse. The study involved semi-structured, individual CIT interviews with health professionals and focus groups with women who had experienced domestic abuse. Twenty-nine health professionals (Midwives, Health Visitors and General Practitioners) participated in the first phase of the study. In the second phase, three focus groups were conducted with a total of 14 women. Data were analysed using a combination of an inductive classification and framework analysis. Findings highlight the points of convergence and divergence between abused women's and health professionals' beliefs about abuse. Although there was some agreement, they do not always share the same views. For example, women want to be asked about abuse, but many health professionals do not feel confident or comfortable discussing the issue. Overall, the study shows the dynamic interaction between women's and health professionals' beliefs about domestic abuse and readiness to discuss and respond to it. Understanding these complex dynamics assists in the employment of

  7. Human Biomonitoring of Engineered Nanoparticles: An Appraisal of Critical Issues and Potential Biomarkers

    Full Text Available The present paper deals with the applicability of biological monitoring to the assessment of exposure and possible effects deriving from exposure to engineered nanomaterials (NM. After establishing a conceptual framework in which human biomonitoring should be placed, the paper reviews the critical issues related to the unusual properties of NM affecting the implementation of biomonitoring activities for this new class of chemicals. Relying on the recent advances in the toxicogenomic, it is possible to assess whether specific biological pathways are activated or perturbed by specific NM. However, to evaluate if quantitative changes in these biomarkers can be used as indicators or predictors for toxicity in humans, validation on well characterised groups of exposed people is needed. At present, it appears more pragmatic to evolve NM-associated biomarker identification considering relevant biological responses found in environmental and occupational studies and assessing the early events associated with exposure to these NM. The battery of biochemical markers includes soluble molecules, antioxidant capacity, peroxidated lipids and carbonyl groups in serum proteins as a biomarkers of systemic inflammation and vascular adhesion molecules to assess endothelial activation/damage. Abnormalities in exhaled breath condensate chemistry reflecting intrinsic changes in the airway lining fluid and lung inflammation seem promising tools suitable for BM studies and are broadly discussed.

    This is a critical review on research conducted in the field of pulmonary delivery of liposomes. Issues relating to the mechanism of nebulisation and liposome composition were appraised and correlated with literature reports of liposome formulations used in clinical trials to understand the role of liposome size and composition on therapeutic outcome. A major highlight was liposome inhalation for the treatment of lung cancers. Many in vivo studies that explored the potential of liposomes as anticancer carrier systems were evaluated, including animal studies and clinical trials. Liposomes can entrap anticancer drugs and localise their action in the lung following pulmonary delivery. The safety of inhaled liposomes incorporating anticancer drugs depends on the anticancer agent used and the amount of drug delivered to the target cancer in the lung. The difficulty of efficient targeting of liposomal anticancer aerosols to the cancerous tissues within the lung may result in low doses reaching the target site. Overall, following the success of liposomes as inhalable carriers in the treatment of lung infections, it is expected that more focus from research and development will be given to designing inhalable liposome carriers for the treatment of other lung diseases, including pulmonary cancers. The successful development of anticancer liposomes for inhalation may depend on the future development of effective aerosolisation devices and better targeted liposomes to maximise the benefit of therapy and reduce the potential for local and systemic adverse effects. © 2016 S.

    From many years now, thanks to the development of modern diving techniques, there has been a rapid spread of diving activities everywhere. In fact, divers are ever more numerous both among the Armed Forces and civilians who dive for work, like fishing, biological research and archeology. The aim of the study was to propose a health protocol for work fitness of professional divers keeping in mind the peculiar work activity, existing Italian legislation that is almost out of date and the technical and scientific evolution in this occupational field. We performed an analysis of the most frequently occurring diseases among professional divers and of the clinical investigation and imaging techniques used for work fitness assessment of professional divers. From analysis of the health protocol recommended by D.M. 13 January 1979 (Ministerial Decree), that is most used by occupational health physician, several critical issues emerged. Very often the clinical investigation and imaging techniques still used are almost obsolete, ignoring the execution of simple and inexpensive investigations that are more useful for work fitness assessment. Considering the out-dated legislation concerning diving disciplines, it is necessary to draw up a common health protocol that takes into account clinical and scientific knowledge and skills acquired in this area. This protocol's aim is to propose a useful tool for occupational health physicians who work in this sector.

  12. The ethics and regulation of overcharging: issues in the commerciality of the health practitioner-patient relationship.

    2014-03-01

    Overcharging by health practitioners is a difficult issue with few guidelines available for practitioners or patients. For the most part it has not been the subject of disciplinary censure and has been dealt with by conciliation processes. However, during 2013 the Singapore High Court twice addressed the commerciality of the health-practitioner-patient relationship, acknowledging that this is a fundamental attribute of the contemporary dynamic between providers and recipients of health services. In Lim Mey Lee Susan v Singapore Medical Council [2013] SGHC 122, it concluded that the obligation to refrain from overcharging is an inherent ethical responsibility of practitioners and affirmed the suspension for three years of a surgeon with Australian training and tertiary connections for what it classified as grossly excessive charging. In Pang Ah San v Singapore Medical Council [2013] SGHC 266, it observed that medical practitioners have a legitimate right to appropriate levels of remuneration but that the right balance has to be struck between professional virtues and business considerations. The Singapore High Court's decisions raise the question of whether professional associations and practitioner regulators have a responsibility to provide guidelines and, potentially, processes by which practical assistance can be provided to medical and other health care practitioners so that they can avoid unacceptable charging practices.

    The aim of this document is to present a critical review of issues concerned with the treatment of the biosphere and geosphere-biosphere interface in long-term performance assessment studies for nuclear waste disposal in Sweden. The review covers three main areas of investigation: a review of SKB's plans for undertaking site investigations at candidate locations for the development of a deep geological repository for spent fuel; identification of critical uncertainties associated with SKB's treatment of the geosphere-biosphere interface in recent performance assessments; and a preliminary modelling investigation of the significance of features, events and processes in the near-surface environment in terms of their effect on the accumulation and redistribution of radionuclides at the geosphere-biosphere interface. Overall, SKB's proposals for site investigations are considered to be comprehensive and, if they can be carried out to the specification presented, will constitute a benchmark that other waste management organisations will have to work hard to emulate. The main concern is that expertise for undertaking the investigations and reporting the results could be stretched very thin. The authors have also identified weaknesses in the documentation concerning the collection of evidence for environmental change and on developing scenarios for future environmental change. A fundamental assumption adopted in the renewed assessment of the SFR 1 repository, which is not discussed or justified in any of the documentation that has been reviewed, is that radionuclides enter the water column of the coastal and lake models directly, without passing first through the bed sediments. The modelling study reported herein suggests that SKB's models are robust to range of alternative conceptual descriptions relating to the geosphere-biosphere interface. There are however situations, in which contaminated groundwater is released via sediment rather than directly

    when an issue of water contamination becomes an issue of environmental injustice? How do we measure the impacts of environmental harm today on future generations? How do we measure the distribution of multiple or cumulative impacts on poorer groups? How do we quantify the responsibility of richer citizens in the world for the environmental harms distributed unequally to the poorer citizens? The papers in this focus issue do not answer all these questions, but we hope that this theme will recur in Environmental Research Letters and that more environmental scientists will begin to frame their analyses around the critical issues of distributions of environmental harms and benefits.

    This feasibility study provides the technical justification for conclusions about K Basin sludge storage options. The conclusions, solely based on criticality safety considerations, depend on the treatment of the sludge. The two primary conclusions are, (1) untreated sludge must be stored in a critically safe storage tank, and (2) treated sludge (dissolution, precipitation and added neutron absorbers) can be stored in a standard Double Contained Receiver Tank (DCRT) or 241-AW-105 without future restrictions on tank operations from a criticality safety perspective.

    Full Text Available Lake Orta, located in Piedmont, northwestern Italy, has been severely affected by industrial pollution since the 1930s. A successful liming intervention, performed in 1988-1990, returned pH levels in the lake to neutrality, and accelerated the reduction of aqueous trace metal concentrations. In this paper, we present an update knowledge of the chemical status of Lake Orta, focusing on the data collected from 1990 to 2014. In this period we sampled the lake at its deepest point (Qualba station, on a monthly (1990-2000 or seasonal (since 2001 basis. Samples were collected at nine depths through the water column, and analyzed for pH, conductivity, alkalinity, major ions, nutrients, and trace metals. Collectively, these data allowed us to evaluate the long-term response of the lake to the restoration treatment, with particular regard to its acid-base status; they also provided insights into emerging or potential critical issues, including eutrophication and re-suspension of trace metals that still linger in the lake. Furthermore, the evaluation of the present chemical condition of the lake is a precondition for any successive restoration measure, such as fish introduction. The recent data confirmed the lake’s water quality has recovered, i.e. returned to a pre-pollution chemical state. Lake water values of pH and concentrations of ammonium, sulphate and base cations have stabilized. Alkalinity and nitrate concentrations are also expected to reach stable level in the next few years. Levels of nitrate, reactive silica, and phosphorus compounds are now regulated by algal uptake, providing indirect evidence of a partial biological recovery. For instance, both the inter-annual average decline and the reappearance of a seasonal signal in silica confirmed the presence of a stable diatom community. The lake is presently oligotrophic, and concentrations of both N and P compounds are steady and low throughout the year. However, a monthly check of nutrient

    The greatest threat to human well-being in this century is climate change and related global issues. We examined the effectiveness of the Modified Instrumentalism in Occupational Therapy model as a framework for facilitating occupational behaviour change to address climate change and related issues. Eleven individuals participated in this mixed-methods single-subject-design study. Data were gathered using the Modified Assessment and Intervention Instrument for Instrumentalism in Occupational Therapy and Daily Occupational Inventories. Quantitative data were analyzed using two- and three-standard deviation band methods. Qualitative data were analyzed using heuristic phenomenological procedures. Occupational performance changed for five participants. Participants' feelings shifted from frustration and helplessness to empowerment and a desire for action. They felt empowered to find occupation-based solutions to the global issues. Occupation-based interventions that increase personal awareness of the connection between occupational performance and global issues could empower people to be agents for action to ameliorate the issues.

    This study group was initiated to consider whether there were any 'show-stopper' issues with accelerators for heavy-ion warm-dense matter (WDM) and heavy-ion inertial fusion energy (HIF), and to prioritize them. Showstopper issues appear to be categorized as limits to beam current; that is, the beam is expected to be well-behaved below the current limit, and significantly degraded in current or emittance if the current limit is exceeded at some region of an accelerator. We identified 14 issues: 1-6 could be addressed in the near term, 7-10 may provide attractive solutions to performance and cost issues, 11-12 address multibeam effects that cannot be more than partially studied in near-term facilities, and 13-14 address new issues that are present in some novel driver concepts. Comparing the issues with the new experimental, simulation, and theoretical tools that we have developed, it is apparent that our new capabilities provide an opportunity to reexamine and significantly increase our understanding of the number one issue--halo growth and mitigation

  12. Critical thinking, nurse education and universities: some thoughts on current issues and implications for nursing practice.

    Science.gov (United States)

    Morrall, Peter; Goodman, Benny

    2013-09-01

    When in the latter part of the 20th century nurse 'training' in the UK left the old schools of nursing (based within the health delivery system) and entered universities, the promise was not just a change of focus from training to education but an embracement of 'higher' education. Specifically, nurses were to be exposed to the demands of thinking rather than just doing - and critical thinking at that. However, despite a history of critical perspectives informing nursing theory, that promise may be turning sour. The insidious saturation of the university system in bureaucracy and managerialism has, we argue, undermined critical thinking. A major funding restructuring of higher education in the UK, coinciding with public concern about the state of nursing practice, is undermining further the viability of critical thinking in nursing and potentially the acceptability of university education for nurses. Nevertheless, while critical thinking in universities has decayed, there is no obvious educational alternative that can provide this core attribute, one that is even more necessary to understand health and promote competent nursing practice in an increasingly complex and globalising world. We propose that nurse academics and their colleagues from many other academic and professional disciplines engage in collegiate 'moral action' to re-establish critical thinking in UK universities.

    A criticality safety analysis has been performed as part of the BN-350 spent fuel disposition project being conducted jointly by the DOE and Kazakhstan. The Kazakhstan regulations are reasonably consistent with those of the DOE. The high enrichment and severe undermoderation of this fast reactor fuel has significant criticality safety consequences. A detailed modeling approach was used that showed some configurations to be safe that otherwise would be rejected. Reasonable requirements for design and operations were needed, and with them, all operations were found to be safe

    The artificial pancreas combines a hormone infusion pump with a continuous glucose monitoring device, supported by a dosing algorithm currently installed on the pump. It allows for dynamic infusions of insulin (and possibly other hormones such as glucagon) tailored to patient needs. For patients with type 1 diabetes the artificial pancreas has been shown to prevent more effectively hypoglycaemic events and hyperglycaemia than insulin pump therapy and has the potential to simplify care. However, the potential ethical issues associated with the upcoming integration of the artificial pancreas into clinical practice have not yet been discussed. Our objective was to identify and articulate ethical issues associated with artificial pancreas use for patients, healthcare professionals, industry and policymakers. We performed a literature review to identify clinical, psychosocial and technical issues raised by the artificial pancreas and subsequently analysed them through a common bioethics framework. We identified five sensitive domains of ethical issues. Patient confidentiality and safety can be jeopardized by the artificial pancreas' vulnerability to security breaches or unauthorized data sharing. Public and private coverage of the artificial pancreas could be cost-effective and warranted. Patient selection criteria need to ensure equitable access and sensitivity to patient-reported outcomes. Patient coaching and support by healthcare professionals or industry representatives could help foster realistic expectations in patients. Finally, the artificial pancreas increases the visibility of diabetes and could generate issues related to personal identity and patient agency. The timely consideration of these issues will optimize the technological development and clinical uptake of the artificial pancreas. Copyright © 2018. Published by Elsevier Masson SAS.

    1995-01-01

    The Fifth International Conference on Nuclear Criticality Safety (ICNC'95) was held September 17-22, 1995, in Albuquerque, New Mexico, USA. Organization and support for the conference was provided by the Sandia National Laboratories (SNL), Los Alamos National Laboratory (LANL), the University of New Mexico, and the Organization for Economic Cooperation and Development (OECD). This conference traces its history back to 1981 when a group of select criticality safety specialists (mostly experimentalists) from France, Germany, Japan, the United Kingdom, and the United States participated in a small conference at LANL in the United States. The motivation for the conference had been provided by Dr. J. C. Manaranche of France who had asked D. Smith and G. E. Whitesides of the United States if it would be possible for the French experimentalists to be able to visit the experimental facilities at LANL. This first conference was followed by a similar conference held in Dijon, France, in 1993. Then in 1987 the conference was hosted by the Japanese and opened to much wider participation by criticality safety specialists involved in experiments, methods development and analysis, and operations. With the 1987 conference in Japan and the fourth conference (ICNC'91) held in the United Kingdom, the interest and international participation by the criticality safety community has grown rapidly. With this background, the occasion of ICNC'95 was one of much expectation

    Singh, R.K.; Chen, Z.; Kumar, D.; Cho, K.; Ollinger, M.

    2002-01-01

    Thin film phosphors have potential applications in field emission flat-panel displays. However, they are limited by the lower cathodoluminescent brightness in comparison to phosphor powders. In this paper, we have investigated the critical parameters that need to be optimized to increase the brightness of phosphor thin films. Specifically, we studied the role of surface roughness and optical properties of the substrate on the brightness of the phosphor films. Thin Y 2 O 3 :Eu phosphor films were deposited on various substrates (lanthanum aluminate, quartz, sapphire, and silicon) with thicknesses varying from 50 to 500 nm. A model that accounts for diffuse and specular or scattering effects has been developed to understand the effects of the microstructure on the emission characteristics of the cathodoluminescent films. The results from the model show that both the optical properties of the substrate and the surface roughness of the films play a critical role in controlling the brightness of laser deposited phosphor films

  16. Regulatory compliance issues related to the White Oak Creek Embayment time-critical removal action

    International Nuclear Information System (INIS)

    Leslie, M.; Kimmel, B.L.

    1991-01-01

    In September 1990, Martin Marietta Energy Systems (Energy Systems) discovered high levels of Cesium-137 ( 137 Cs) in surface sedimenus near the mouth of White Oak Creek Embayment (WOCE). White Oak Creek (WOC) receives surface water drainage from Oak Ridge National Laboratory. Since this discovery, the Department of Energy (DOE) and Energy Systems have pursued actions designed to stabilize the contaminated WOCE sediments under provisions of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), and the implementing regulations in the National Contingency Plan (NCP) (40 CFR Part 300), as a time-critical removal action. By definition, a time-critical removal is an action where onsite activities are initiated within six months of the determination that a removal action is appropriate. Time-critical removal actions allow comparatively rapid mobilization to protect human health and the environment without going through the lengthy and extensive CERCLA Remedial Investigation/Feasibility Study/Record of Decision process. Many aspects of the project, in terms of compliance with the substantive requirements of the NCP and ARARs, have exceeded the regulatory requirements, despite the fact that there is no apparent authority on conducting removal actions at Federal facilities. Much of the interpretation of the NCP was groundbreaking in nature for both EPA and DOE. 4 refs., 2 figs

    Jones, R.L.

    1996-01-01

    Recent corrosion experience in US light water reactor nuclear power plants is reviewed with emphasis on mitigation strategies to control the cost of corrosion to LWR operators. Many components have suffered corrosion problems resulting in industry costs of billions of dollars. The most costly issues have been stress corrosion cracking of stainless steel coolant piping in boiling water reactors and corrosion damage to steam generator tubes in pressurized water reactors. Through industry wide R and D programs these problems are now understood and mitigation strategies have been developed to address the issues in a cost effective manner. Other significant corrosion problems for both reactor types are briefly reviewed. Tremendous progress has been made in controlling corrosion, however, minimizing its impact on plant operations will present a continuing challenge throughout the remaining service lives of these power plants

  1. Critical issues with clinical research in children: The example of premature infants

    International Nuclear Information System (INIS)

    Welty, Stephen E.

    2005-01-01

    Research in pediatrics has led to marked improvements in survival in pediatric patients. In no other age group have these improvements been more dramatic than in neonatology, where antenatal steroid administration to mothers and postnatal utilization of surfactant have led to marked improvements in survival so that infants born at 24 weeks gestation now have a greater than 50% chance of survival. Unfortunately, more than 50% of these patients develop significant complications of prematurity with potential long-term impact on the health of these infants. Therefore, additional research must be done in these patients to prevent these complications or reduce the impact of these complications. There are many practical and some ethical issues that could impede research in the area. Interventional studies have succeeded because literally decades of research defined unequivocally the pathophysiology of diseases such as surfactant deficiency in RDS. Unfortunately, the pathophysiology leading to the complications of prematurity has been extrapolated from old concepts without verification as the population has become smaller and more premature than the previous era. Thus, an extremely important practical issue in pediatric research is whether to design interventions to address the extrapolated pathophysiology risking misinterpretations of the results of such studies. Or should our efforts be focused on defining endpoints associated with the development of diseases and complications which may define pathophysiology more completely but delay the design of interventions to improve the outcomes of patients. Another crucial practical issue in pediatric research is how to power studies so that interventions can be studied adequately. In the US, large neonatal networks have been formed so that large databases can be created and large multi-center trials can be performed. The practical issues associated with these network studies is the center to center variability in patient care

    This report analyses latent factors of a human behavior directly contributing to the criticality accident. It is pouring some 16 kg-U with an enrichment of 18.8% into the precipitation tank. It is the fact that the direct cause of this accident is the workers' unsafe act. However, the authors find lots of latent factors relating to the production-biased company's policy, the poor climate for safety in the work place, the inadequate safety management and the unsuitable equipment. This accident was caused by many organizational factors. This paper also discusses lessons learned from this accident. (author)

    2016-03-01

    Full Text Available Background: Disasters cause almost 100 thousand deaths and affect 200 million people every year. Operators working in disaster zones reported problems in importing medications, in particular pain killers and narcotics, in areas of disasters. The importance of ensuring access to painkillers, including major analgesics, is pinpointed by the World Health Organization which through its “Access to Controlled Medications Programme” provides normative guidance, policy analysis and training of healthcare workers on this issue. Nevertheless the little evidence available on the assessment and treatment of pain in disasters suggests that the management of pain in disaster zones may be affected by several factors mainly due to the availability of drugs, the skills of health personnel and cultural issues. Aim:The main aims of this project are: evaluating whether pain is correctly assessed and treated in disaster zones, assessing which are the main limitations to its treatment and producing suggestions and reccomandations to improve its treatment. Materials & Methods: In order to achieve our aims we will adopt a combined approach made by: A systematic review of the evidence will be conducted in the scientific databases Medline and Scopus. A review of grey literature concerning the issue on the Web pages of international organizations and NGOs working in the field of humanitarian aid. A survey among healthcare workers who took part to the international humanitarian actions. A survey among expert of the humanitarian field not necessary involved in projects on the field e.g. lawyer expert in international law, international organizations representatives working in the headquarters etc. A technical table with European experts in the field of pain treatment and/or disaster reaponse.

    In the ITER-FEAT, the most severe loading conditions for the VV are the toroidal field coil fast discharge (TFCFD) and its load combination with electromagnetic loads due to a plasma vertical instability, which cause high compressive stresses in the VV inboard wall and increase the risk of buckling. Detailed analyses need to be performed to assess the stress level at the geometrical discontinuities and where concentrated loads are applied. The nuclear heating and the presence of gaps between the blanket modules cause concentrated nuclear heat loads.

  8. Are optimal CO2 emissions really optimal? Four critical issues for economists in the greenhouse

    International Nuclear Information System (INIS)

    Azar, C.

    1998-01-01

    Although the greenhouse effect is by many considered as one of the most serious environmental problems, several economic studies of the greenhouse effect, most notably Nordhaus's DICE model, suggest that it is optimal to allow the emissions of greenhouse gases (GHG) to increase by a factor of three over the next century. Other studies have found that substantial reductions can be justified on economic grounds. This paper explores into the reasons for these differences and identifies four (partly overlapping) crucial issues that have to be dealt with when analysing the economics of the greenhouse effect low-probability but catastrophic events; cost evaluation methods; the choice of discount rate; the choice of decision criterion. The paper shows that (1) these aspects are crucial for the policy conclusions drawn from models of the economics of climate change, and that (2) ethical choices have to be made for each of these issues. This fact needs wider recognition since economics is very often perceived as a value neutral tool that can be used to provide policy makers with 'optimal' policies. 62 refs

  9. Online Higher Education Instruction to Foster Critical Thinking When Assessing Environmental Issues - the Brownfield Action Model

    Science.gov (United States)

    Bower, Peter; Liddicoat, Joseph; Dittrick, Diane; Maenza-Gmelch, Terryanne; Kelsey, Ryan

    2013-04-01

    According to the Environmental Protection Agency, there are presently over half a million brownfields in the United States, but this number only includes sites for which an Environmental Site Assessment has been conducted. The actual number of brownfields is certainly into the millions and constitutes one of the major environmental issues confronting all communities today. Taught in part online for more than a decade in environmental science courses at over a dozen colleges, universities, and high schools in the United States, Brownfield Action (BA) is an interactive, web-based simulation that combines scientific expertise, constructivist education philosophy, and multimedia to advance the teaching of environmental science (Bower et al., 2011). In the online simulation and classroom, students form geotechnical consulting companies, conduct environmental site assessment investigations, and work collaboratively to solve a problem in environmental forensics. The BA model contains interdisciplinary scientific and social information that are integrated within a digital learning environment that encourages students to construct their knowledge as they learn by doing. As such, the approach improves the depth and coherence of students understanding of the course material. Like real-world environmental consultants, students are required to develop and apply expertise from a wide range of fields, including environmental science and engineering as well as journalism, medicine, public health, law, civics, economics, and business management. The overall objective is for students to gain an unprecedented appreciation of the complexity, ambiguity, and risk involved in any environmental issue or crisis.

    Directory of Open Access Journals (Sweden)

    Francesca eCicchetti

    2014-07-01

    Full Text Available The role of glial cells in the pathogenesis of many neurodegenerative conditions of the central nervous system (CNS is now well established (as is discussed in other reviews in this special issue of Frontiers in Neuropharmacology. What is less clear is whether there are changes in these same cells in terms of their behaviour and function in response to invasive experimental therapeutic interventions for these diseases. This has, and will continue to, become more of an issue as we enter a new era of novel treatments which require the agent to be directly placed/infused into the CNS such as deep brain stimulation, cell transplants, gene therapies and growth factor infusions. To date, all of these treatments have produced variable outcomes and the reasons for this have been widely debated but the host astrocytic and/or microglial response induced by such invasively delivered agents has not been discussed in any detail. In this review, we have attempted to summarise the limited published data on this, in particular we discuss the small number of human post-mortem studies reported in this field. By so doing, we hope to provide a better description and understanding of the extent and nature of both the astrocytic and microglial response, which in turn could lead to modifications in the way these therapeutic interventions are delivered.

    Critical heat flux (CHF) is manifested by sharp reduction in heat transfer coefficient and a drastic rise in fuel rod surface temperature, which may lead to failure of the fuel cladding and is of immense importance in reactor design and operation. In this paper, the existing literature on CHF is studied and analyzed. Different modeling techniques such as geometry modeling and fluid modeling are highlighted. CHF enhancement techniques such as swirl flow, porous coating, nano-fluids or mechanical vibrations are analyzed and their suitability for different applications is discussed. The advances in prediction methods for tubes and rod bundles are also presented. CHF correlations and their applications have been compiled to estimate the CHF for fluids other than water or other geometries. Finally, future research needs are identified and presented. (authors)

    Messing, K

    1997-01-01

    Action to improve women's occupational health has been slowed by a notion that women's jobs are safe and that any health problems identified among women workers can be attributed to unfitness for the job or unnecessary complaining. With increasing numbers of women in the labor force, the effects of work on women's health have recently started to interest health care providers, health and safety representatives and researchers. We begin our summary of their discoveries with a discussion of women's place in the workplace and its implications for occupational health, followed by a brief review of some gender-insensitive data-gathering techniques. We have then chosen to concentrate on the following four areas: methods and data collection; directing attention to women's occupational health problems; musculoskeletal disease; mental and emotional stress. We conclude by pointing out some neglected occupational groups and health issues.

    2013-05-01

    This paper presents the experience on the design and implementation of a user-centered Oncology Information System developed for the Medical Oncology Department at the "Hospital Universitario Virgen de la Victoria", in Málaga, Spain. The project focused on the aspects considered in the literature as critical factors for a successful deployment and usage of a health information system. System usability, adequate technology, integration of clinical routines, real-time statistical analysis of data, information confidentiality and standard protocol-based external interconnection were the key aspects considered. The developed system is based on a web application with a modular and layered architecture accounting for usability, ease of maintenance and further system development. Evaluation of system usability was carried at three and fifteen months after system deployment to analyze the advantages/disadvantages experienced by the end-users. A thorough prior analysis of clinical activities and workflows, the use of the adequate technology, and the availability of data analysis tools will almost guarantee success in the deployment of an Oncology Information System.

  19. Critical Issues for Producing UHTC-Brazed Joints: Wetting and Reactivity

    Science.gov (United States)

    Passerone, A.; Muolo, M. L.; Valenza, F.

    2016-08-01

    A brief survey is presented of the most important interaction phenomena occurring at the solid-liquid interfaces in metal-ceramic systems at high temperatures, with special attention to the most recent developments concerning wetting and joining transition metals diborides. These phenomena are described and discussed from both the experimental and theoretical points of view in relation to joining ceramic and metal-ceramic systems by means of processes in the presence of a liquid phase (brazing, TLPB etc.). It is shown that wetting and the formation of interfacial dissolution regions are the results of the competition between different phenomena: dissolution of the ceramic in the liquid phase, reaction and formation of new phases at the solid-liquid interface, and drop spreading along the substrate surface. We emphasize the role of phase diagrams to support both the design of the experiments and the choice of active alloying elements, and to interpret the evolution of the system in relation to temperature and composition. In this respect, the sessile-drop technique has been shown to be helpful in assessing critical points of newly calculated phase diagrams. These studies are essential for the design of joining processes, for the creation of composite materials, and are of a particular relevance when applied to UHTC materials.

  20. Immune Monitoring in Cancer Vaccine Clinical Trials: Critical Issues of Functional Flow Cytometry-Based Assays

    2013-01-01

    Full Text Available The development of immune monitoring assays is essential to determine the immune responses against tumor-specific antigens (TSAs and tumor-associated antigens (TAAs and their possible correlation with clinical outcome in cancer patients receiving immunotherapies. Despite the wide range of techniques used, to date these assays have not shown consistent results among clinical trials and failed to define surrogate markers of clinical efficacy to antitumor vaccines. Multiparameter flow cytometry- (FCM- based assays combining different phenotypic and functional markers have been developed in the past decade for informative and longitudinal analysis of polyfunctional T-cells. These technologies were designed to address the complexity and functional heterogeneity of cancer biology and cellular immunity and to define biomarkers predicting clinical response to anticancer treatment. So far, there is still a lack of standardization of some of these immunological tests. The aim of this review is to overview the latest technologies for immune monitoring and to highlight critical steps involved in some of the FCM-based cellular immune assays. In particular, our laboratory is focused on melanoma vaccine research and thus our main goal was the validation of a functional multiparameter test (FMT combining different functional and lineage markers to be applied in clinical trials involving patients with melanoma.

    Mallett, Xanthé; Evison, Martin P

    2017-06-01

    The aim of this brief critical qualitative analysis is to examine the development of forensic anthropology in Australia, at a time of significant change in the discipline. It will briefly summarise its historical establishment, making comparative reference to other regions-particularly the United Kingdom and United States, and the influence of the Bali Bombings of 2002, Indian Ocean earthquake and tsunami of 2004 and Black Saturday Bushfires of 2009. The analysis goes on to consider key factors in research in forensic anthropology in the United States, and the development of standards and regulation in the US and UK. The significance of research in post-mortem diagenesis in Brazil-a country sharing aspects of climate, soil types and demography with Australia-is also considered, as well as the significance of patterns of casework encountered in Australia compared with those of other jurisdictions. While forensic anthropology as a discipline has grown remarkably in recent years, this analysis suggests that research and training tailored to the specific pattern of casework encountered in Australia is now essential to support the development of national standards in science, education, and professional regulation. The significance of the establishment of the first taphonomy research facility outside of the US-the Australian Facility for Taphonomic Experimental Research-is briefly considered with reference to what this facility may offer to the development of forensic anthropology in Australia.

    2016-02-01

    Milrinone is an inotropic drug used in a variety of clinical settings in adults and children. The efficacy of milrinone in pediatric low-cardiac output syndrome after cardiac surgery is reported. Its primary route of removal from the body is through the kidney as unchanged drug in the urine. Milrinone is not known to be efficiently removed by extracorporeal dialytic therapies and thus has the potential to cause serious adverse effects and potentially worsens renal function in patients experiencing acute kidney injury (AKI). AKI is an important public health issue that is associated with increased morbidity, mortality, and cost. It is a known risk factor for the development of chronic kidney disease. There are no specific therapies to mitigate AKI once it has developed, and interventions are focused on supportive care and dose adjustment of medications. Estimating glomerular filtration rate based on height and serum creatinine is the most commonly used clinical method for assessing kidney function and modification of medication doses. The purpose of this review is to discuss our current understanding of milrinone pharmacokinetics and pharmacodynamics in children with AKI and to describe the potential use of urinary biomarkers to guide therapeutic decision making for milrinone dosing.

  4. Getting ready for malaria elimination: a check list of critical issues to consider

    2014-08-01

    Full Text Available In recent years, a renewed interest in malaria elimination and eradication has emerged and seems to be rooting in the minds of the scientific community, public health specialists, funding bodies, policy makers and politicians. Malaria eradication will certainly benefit from improved and innovative tools; notwithstanding novel knowledge in fields ranging from basic science to mathematical modelling and health systems research. However, the elimination of malaria also encompasses a broad range of essential aspects that countries and other actors need to consider when thinking of embarking on such an adventure, including the implementation of innovative strategies, the ability to incorporate the most up-to-date evidence into policy, the integration of malaria into the broader health agenda, the strengthening of surveillance and health systems, capacity building, funding, advocacy and, very importantly, research. While in some cases this enthusiasm is clearly justified, some countries are still a long way from realistically advancing towards elimination. This paper attempts to provide guidance on all the necessary issues that should be considered when initiating a malaria elimination program.

  5. Burnout in Orthopaedic Surgeons: A Challenge for Leaders, Learners, and Colleagues: AOA Critical Issues.

    Science.gov (United States)

    Ames, S Elizabeth; Cowan, James B; Kenter, Keith; Emery, Sanford; Halsey, David

    2017-07-19

    Burnout, depression, suicidal ideation, and dissatisfaction with work-life balance have been reported in all medical specialties and at all stages of medical education and practice experience. Burnout consists of progressive emotional, attitudinal, and physical exhaustion. Physicians with burnout may treat patients as objects and feel emotionally depleted. Burnout is characterized by a loss of enthusiasm for work (emotional exhaustion), feelings of cynicism (depersonalization), and a low sense of personal accomplishment. The most complete study of emotional burnout among different medical specialties demonstrated that orthopaedic surgery is one of the specialties with the highest burnout rate. Qualitative descriptive studies are available. There was a 45.8% burnout rate among physicians in the U.S. in 2012, and a 2014 update suggested even higher rates. Burnout has a correlation with medical education. Burnout rates are similar to those in the general population when medical students enter school, and increase steadily through medical education prior to residency. Burnout rates in residents are high, reported to be between 41% and 74% across multiple specialties. This impacts our young physician workforce in orthopaedics. The purpose of this review is to provide the available information that characterizes burnout and addresses the issues inherent to preventing burnout, and to build awareness in orthopaedic surgeons. Wellness "goes beyond merely the absence of distress and includes being challenged, thriving, and achieving success in various aspects of personal and professional life." The challenge for the orthopaedic community is to develop interventions and strategies that are personalized to the individuals in this specialty.

    Several continuous splits for wafer alignment target topography conditions to improve epitaxy film alignment were applied. The alignment evaluation among former layer pad oxide thickness (250 angstrom - 500 angstrom), drive oxide thickness (6000 angstrom - 10000 angstrom), nitride film thickness (600 angstrom - 1500 angstrom), initial oxide etch (fully wet etch, fully dry etch and dry plus wet etch) will be split to this experiment. Also various epitaxy deposition recipe such as: epitaxy source (SiHCl2 or SiCHCl3) and growth rate (1.3 micrometer/min approximately 2.0 micrometer/min) will be used to optimize the process window for alignment issue. All the reflectance signal and cross section photography of alignment target during NIKON stepper alignment process will be examined. Experimental results show epitaxy recipe plays an important role to wafer alignment. Low growth rate with good performance conformity epitaxy lead to alignment target avoid washout, pattern shift and distortion. All the results (signal monitor and film character) combined with NIKON's stepper standard laser scanning alignment system will be discussed in this paper.

    As the fraction of electricity generated from intermittent renewable sources (such as solar and wind) grows, developing reliable energy storage technologies to store electrical energy in large scale is of increasing importance. Redox flow batteries are now enjoying a renaissance and regarded as a leading technology in providing a well-balanced solution for current daunting challenges. In this article, state-of-the-art studies of the complex multicomponent transport phenomena in aqueous redox flow batteries, with a special emphasis on all-vanadium redox flow batteries, are reviewed and summarized. Rather than elaborating on the details of previous experimental and numerical investigations, this article highlights: i) the key transport issues in each battery's component that need to be tackled so that the rate capability and cycling stability of flow batteries can be significantly improved, ii) the basic mechanisms that control the active species/ion/electron transport behaviors in each battery's component, and iii) the key experimental and numerical findings regarding the correlations between the multicomponent transport processes and battery performance.

    Manca, G; Volterrani, D; Mazzarri, S; Duce, V; Svirydenka, A; Giuliano, A; Mariani, G

    2014-06-01

    Although, like the axilla, the internal mammary nodes (IMNs) are a first-echelon nodal drainage site in breast cancer, the importance of their treatment has long been debated. Seminal randomized trials have failed to demonstrate a survival benefit from surgical IMN dissection, and several retrospective studies have shown that IMNs are rarely the first site of recurrence. However, the recent widespread adoption of sentinel lymph node (SLN) biopsy has stimulated a critical reappraisal of such early results. Furthermore, the higher proportion of screening-detected cancers, improved imaging and techniques (i.e., lymphoscintigraphy for radioguided SLN biopsy) make it possible to visualize lymphatic drainage to the IMNs. The virtually systematic application of adjuvant systemic and/or loco-regional radiotherapy encourages re-examination of the significance of IMN metastases. Moreover, randomized trials testing the value of postmastectomy irradiation and a meta-analysis of 78 randomized trials have provided high levels of evidence that local-regional tumor control is associated with long-term survival improvements. This benefit was limited to trials that used systemic chemotherapy, which was not routinely administered in the earlier studies. However, the contribution from IMN treatment is unclear. Lymphoscintigraphic studies have shown that a significant proportion of breast cancers have primary drainage to the IMNs, including approximately 30% of medial tumors and 15% of lateral tumors. In the few studies where IMN biopsy was performed, 20% of sentinel IMNs were metastatic. The risk of IMN involvement is higher in patients with medial tumors and positive axillary nodes. IMN metastasis has prognostic significance, as recognized by its inclusion in the American Joint Committee on Cancer staging criteria, and seems to have similar prognostic importance as axillary nodal involvement. Although routine IMN evaluation might be indicated, it has not been routinely performed

  14. Issues involved in food irradiation and its commercial application: a discussion paper prepared for the Primary and Allied Industries Council

    International Nuclear Information System (INIS)

    1988-01-01

    The Australian Department of Primary Industries and Energy's interest in food irradiation stems from its responsibilities under the Export Control Act (1982) and the Quarantine Act (1908) and the implications this process may have for Australian food exports and quarantine control. Food irradiation is regarded by the Department as a process which may provide an alternative to some existing conventional food treatments. It is not expected to replace completely other processes, but subject to the overseas acceptance of imported irradiated foods, it could offer Australian exporters an additional processing and/or quarantine treatment. The Department's position is that foods irradiated in approved facilities in Australia could be approved for export provided they comply with the regulatory requirements of the importing country and are appropriately labelled or identified. The Department maintains the view that the choice to use this technology is a commercial decision which will depend on many factors including: acceptability of the toxicological aspects, demand for benefits it provides, its cost and competitiveness with alternative treatments, approval by Australian and international regulatory authorities, and importantly, the willingness of consumers to buy irradiated foods

  15. Performance assessment and licensing issues for United States commercial near-surface low-level radioactive waste disposal facilities

    International Nuclear Information System (INIS)

    Birk, S.M.

    1997-10-01

    The final objective of performance assessment for a near-surface LLW disposal facility is to demonstrate that potential radiological impacts for each of the human exposure pathways will not violate applicable standards. This involves determining potential pathways and specific receptor locations for human exposure to radionuclides; developing appropriate scenarios for each of the institutional phases of a disposal facility; and maintaining quality assurance and control of all data, computer codes, and documentation. The results of a performance assessment should be used to demonstrate that the expected impacts are expected to be less than the applicable standards. The results should not be used to try to predict the actual impact. This is an important distinction that results from the uncertainties inherent in performance assessment calculations. The paper discusses performance objectives; performance assessment phases; scenario selection; mathematical modeling and computer programs; final results of performance assessments submitted for license application; institutional control period; licensing issues; and related research and development activities

    There is an important body of literature using multi-criteria distance function methods for the aggregation of a battery of sustainability indicators in order to obtain a composite index. This index is considered to be a proxy of the sustainability goodness of a natural system. Although this approach has been profusely used in the literature, it is not exempt from difficulties and potential pitfalls. Thus, in this paper, a significant number of critical issues have been identified showing different procedures capable of avoiding, or at least of mitigating, the inherent potential pitfalls associated with each one. The recommendations made in the paper could increase the theoretical soundness of the multi-criteria distance function methods when this type of approach is applied in the sustainability field, thus increasing the accuracy and realism of the sustainability measurements obtained.

    2015-01-01

    This critical review presents several aspects related to the use of copper as a main component in brake pads in road vehicles. The compositions of these materials are attracting increasing interest and concern due to the relative contribution of wear products to particulate matter emissions in the environment as a result of braking action even though there has been a reduction in exhaust products from internal combustion engines. We review the data on the main wear mechanisms in brake systems and highlight the positive role of copper. However, similar to other heavy metal emissions, even the release of copper into the atmosphere may have important environmental and health effects. Thus, several replacement strategies are being pursued, and the positive and negative features will be critically reviewed. Additionally, the future perspectives in materials development will be discussed. - Highlights: • Copper in brake pad materials: role and concerns. • Environmental and health impact of copper. • Copper replacement in frictional brake materials. • International legislation and standards on the above issues. - Importance of copper in brake pad materials and concern as regards environmental and health impact of its emission as brake wear product.

    2003-01-01

    Recent results from DIII-D address critical internal transport barrier (ITB) research issues relating to sustainability, impurity accumulation and ITB control, and have also demonstrated successful application of general profile control tools. In addition, substantial progress has been made in understanding the physics of the Quiescent Double Barrier (QDB) regime, increasing the demonstrated operating space for the regime and improving performance. Highlights include: (1) A clear demonstration of q-profile modification using electron cyclotron current drive (ECCD); (2) Successful use of localized profile control using electron cyclotron heating (ECH) or ECCD to reduce central high-Z impurity accumulation associated with density peaking; (3) Theory based modeling codes are now being used to design experiments; (4) The operating space for Quiescent H-mode (QH-mode) has been substantially broadened, in particular higher density operation has been achieved; (5) Both absolute (β≤ 3.8%, neutron rate S n ≤ 5.5x10 15 s -1 ) and relative (β N H 89 = 7 for 10τ E ) performance has been increased; (6) With regard to sustainment, QDB plasmas have been run for 3.8 s or 26 τ E . These results emphasize that it is possible to produce sustained high quality H-mode performance with an edge localized mode (ELM)-free edge, directly addressing a major issue in fusion research, of how to ameliorate or eliminate ELM induced pulsed divertor particle and heat loads.

    The increase in pulse duration and cumulative run-time, together with the increase of the plasma energy content, will represent the largest changes in operation conditions in future fusion devices such as the International Thermonuclear Experimental Reactor (ITER) compared to today's experimental facilities. These will give rise to important plasma-physics effects and plasma-material interactions (PMIs) which are only partially observed and accessible in present-day experiments and will open new design, operation and safety issues. For the first time in fusion research, erosion and its consequences over many pulses (e.g., co-deposition and dust) may determine the operational schedule of a fusion device. This paper identifies the most critical issues arising from PMIs which represent key elements in the selection of materials, the design, and the optimisation of plasma-facing components (PFCs) for the first-wall and divertor. Significant advances in the knowledge base have been made recently, as part of the R and D supporting the engineering design activities (EDA) of ITER, and some of the most relevant data are reviewed here together with areas where further R and D work is urgently needed

    DNA barcoding has been proposed as a useful tool for forensic wood identification and development of a reliable DNA reference library is an essential first step. Xylaria (wood collections) are potentially enormous data repositories if DNA information could be extracted from wood specimens. In this study, 31 xylarium wood specimens and 8 leaf specimens of six important commercial species of Pterocarpus were selected to investigate the reliability of DNA barcodes for authentication at the species level and to determine the feasibility of building wood DNA barcode reference libraries from xylarium specimens. Four DNA barcodes (ITS2, matK, ndhF-rpl32 and rbcL) and their combination were tested to evaluate their discrimination ability for Pterocarpus species with both TaxonDNA and tree-based analytical methods. The results indicated that the combination barcode of matK + ndhF-rpl32 + ITS2 yielded the best discrimination for the Pterocarpus species studied. The mini-barcode ndhF-rpl32 (167-173 bps) performed well distinguishing P. santalinus from its wood anatomically inseparable species P. tinctorius. Results from this study verified not only the feasibility of building DNA barcode libraries using xylarium wood specimens, but the importance of using wood rather than leaves as the source tissue, when wood is the botanical material to be identified.

    The aim of the present paper was to show that differences in biological activity among commercially produced vermicompost samples can be found by using a relatively simple test system consisting of microorganism tests on six microbiological media and soilless seedling growth tests with four vegetable crop species. Significant differences in biological properties among analyzed samples were evident both at the level of microbial load as well as plant growth-affecting activity. These differences were mostly manufacturer- and feedstock-associated, but also resulted from storage conditions of vermicompost samples. A mature vermicompost sample that was produced from sewage sludge still contained considerable number of Escherichia coli. Samples from all producers contained several potentially pathogenic fungal species such as Aspergillus fumigatus, Pseudallescheria boidii, Pseudallescheria fimeti, Pseudallescheria minutispora, Scedosporium apiospermum, Scedosporium prolificans, Scopulariopsis brevicaulis, Stachybotrys chartarum, Geotrichum spp., Aphanoascus terreus, and Doratomyces columnaris. In addition, samples from all producers contained plant growth-promoting fungi from the genera Trichoderma and Mortierella. The described system can be useful both for functional studies aiming at understanding of factors affecting quality characteristics of vermicompost preparations and for routine testing of microbiological quality and biological activity of organic waste-derived composts and vermicomposts.

  3. Enabling the Distributed Generation Market of High Temperature Fuel Cell and Absorption Chiller Systems to Support Critical and Commercial Loads

    DiMola, Ashley M.

    Buildings account for over 18% of the world's anthropogenic Greenhouse Gas (GHG) emissions. As a result, a technology that can offset GHG emissions associated with buildings has the potential to save over 9 Giga-tons of GHG emissions per year. High temperature fuel cell and absorption chiller (HTFC/AC) technology offers a relatively low-carbon option for meeting cooling and electric loads for buildings while producing almost no criteria pollutants. GHG emissions in the state of California would decrease by 7.48 million metric tons per year if every commercial building in the State used HTFC/AC technology to meet its power and cooling requirements. In order to realize the benefits of HTFC/AC technology on a wide scale, the distributed generation market needs to be exposed to the technology and informed of its economic viability and real-world potential. This work characterizes the economics associated with HTFC/AC technology using select scenarios that are representative of realistic applications. The financial impacts of various input factors are evaluated and the HTFC/AC simulations are compared to the economics of traditional building utilities. It is shown that, in addition to the emissions reductions derived from the systems, HTFC/AC technology is financially preferable in all of the scenarios evaluated. This work also presents the design of a showcase environment, centered on a beta-test application, that presents (1) system operating data gathered using a custom data acquisition module, and (2) HTFC/AC technology in a clear and approachable manner in order to serve the target audience of market stakeholders.

    Angiogenesis, the formation of new blood-vessel, is crucial in the pathogenesis of several diseases, and thus represents a druggable target for the prevention and treatment of different disorders. It is nowadays well kwon how diet can control cancer development and progression, and how the use of certain diet components can prevent cancer development. Several studies, also from our lab, now indicate that natural plant products including nutraceuticals modulate tumor angiogenesis. In this review, it is reported how phytochemicals, comprising hydroxytyrosol, resveratrol, genistein, curcumin, and the green tea component epigallocatechin-3-gallate among the others, negatively regulate angiogenesis. A single plant-derived compound may affect both endothelial and tumor cells, with the common denominator of anti-inflammatory and radical scavenger activities. Beside these positive features, documented in cellular and animal models, a series of critical issues should be considered from a pharmacological point of view as: what is the best source of bioactive compounds: food and beverages, extracted phytocomplexes, isolated nutraceuticals or synthetic analogues? How is the bioavailability of the compounds of interest in relation to the above source? Is there any biological activity by circulating metabolic derivatives? What is the best formulation, administration route and posology? How safe are in humans? How strong and reliable are the clinical trials designed for their use alone or in combination with conventional chemotherapy? After a dissertation of these critical points, the conclusion can be drawn that novel and effective strategies should be optimized to improve their bioavailability and efficacy, considering their exploitation as chemopreventive and/or curative approaches.

    2010-10-15

    The final report for IEA Wind Task 23, Offshore Wind Energy Technology and Deployment, is made up of two separate reports: Subtask 1: Experience with Critical Deployment Issues and Subtask 2: Offshore Code Comparison Collaborative (OC3). The Subtask 1 report included here provides background information and objectives of Task 23. It specifically discusses ecological issues and regulation, electrical system integration and offshore wind, external conditions, and key conclusions for Subtask 1. A comprehensive approach to planning is needed that integrates impacts on ecology, the effects of electrical infrastructure, and the layout of wind farms. Governments, which usually finance ecological research, should disclose results for wide dissemination as they become available. As example the workshop held suggested that documents covering the issues like offshore wind energy legislation, Guidelines for EIAs and SEAs and best practices need to be produced and distributed on a regular basis, as ecological research progresses and experience from the planning and operation of existing wind farms emerges. Research should help strike the balance between optimum regulation and the need to get projects up and running. Such research is needed to increase understanding of offshore wind metrology and its impact on electrical power fluctuations. More work is needed to develop special grid code and standards for offshore. The transient behavior of large cable installations (switching / harmonic/ Behavior and modeling of large HV cable systems) must be better understood. Connection and control systems must be developed for large offshore wind farms. Work is needed to develop the technical architecture of offshore wind grid systems. Public access to measurements (e.g., turbine power output, meteorological masts, buoys) is important, especially for model validation. Determining wake effects is currently the most important challenge in wind engineering. Emphasis should be put into

    1991-01-01

    In this paper the authors attempt to motivate the development of modeling tools for linear induction accelerator components by giving examples of performance limitations related to energy sweep. The most pressing issues is the development of an accurate model of the switching behavior of large magnetic cores at high dB/dt in the accelerator and magnetic compression modulators. Ideally one would like to have a model with as few parameters as possible that allows the user to choose the core geometry and magnetic material and perhaps a few parameters characterizing the switch model. Beyond this, the critical modeling tasks are: simulation of a magnetic compression modulator, modeling the reset dynamics of a magnetic compression modulator, modeling the loading characteristics of a linear induction accelerator cell, and modeling the electron injector current including the dynamics of feedback modulation and beam loading in an accelerator cell. Of course in the development of these models care should be given to benchmarking them against data from experimental systems. Beyond that one should aim for tools that have predictive power so that they can be used as design tools and not merely to replicate existing data

    Develop an effective First Aid's system in workplaces is significantly important to the outcomes of accidents at work, thus contributing positively to create healthy and safe environments, improving responsible attitude and risk perception by workers. The italian regulation (D. Lgs. 81/08; DM 388/03) gives an important role to First Aid within the system for managing health and safety in workplaces and requires the employers to designate and train workers and organize facilities in the workplace. However, to ensure that First Aid's system actually contributes to increasing health and safety in workplaces, it's necessary to verify its effectiveness, beyond the law compliance. The article stands to evaluate the critical issues and related innovations to be introduced in this context, by analyzing data from literature and field experiences involving actors in the prevention system. The goal is to provide suggestions and action proposals to improve first aid's system in workplaces, paying particular attention to the aiders training (selection, motivation, teaching methods, retraining), as well as introduce to innovations to allow an immediate and timely emergency response (company equipments, other useful devices). On this last aspect, it has given particular emphasis to the introduction of semi-automatic defibrillator (AED), which is essential in case of sudden cardiac arrest with ventricular fibrillation, and special aiders training by means of BLSD (Basic Life Support and Defibrillation) courses based on international guidelines.

    A technical assessment of the critical issues and problem areas in the field of plasma materials interactions (PMI) in magnetic fusion devices shows these problems to be central for near-term experiments, for intermediate-range reactor devices including D-T burning physics experiments, and for long-term reactor machines. Critical technical issues are ones central to understanding and successful operation of existing and near-term experiments/reactors or devices of great importance for the long run, i.e., ones which will require an extensive, long-term development effort and thus should receive attention now. Four subgroups were formed to assess the critical PMI issues along four major lines: (1) PMI and plasma confinement physics experiments; (2) plasma-edge modelling and theory; (3) surface physics; and (4) materials technology for in-vessel components and the first wall. The report which follows is divided into four major sections, one for each of these topics

    Unconventional natural gas and oil resources in the United States are important components of a national energy program. While the Nation seeks greater energy independence and greener sources of energy, Federal agencies with environmental responsibilities, state and local regulators and water-resource agencies, and citizens throughout areas of unconventional shale gas development have concerns about the environmental effects of high volume hydraulic fracturing (HVHF), including those in the Appalachian Basin in the northeastern United States (fig. 1). Environmental concerns posing critical challenges include the availability and use of surface water and groundwater for hydraulic fracturing; the migration of stray gas and potential effects on overlying aquifers; the potential for flowback, formation fluids, and other wastes to contaminate surface water and groundwater; and the effects from drill pads, roads, and pipeline infrastructure on land disturbance in small watersheds and headwater streams (U.S. Government Printing Office, 2012). Federal, state, regional and local agencies, along with the gas industry, are striving to use the best science and technology to develop these unconventional resources in an environmentally safe manner. Some of these concerns were addressed in U.S. Geological Survey (USGS) Fact Sheet 2009–3032 (Soeder and Kappel, 2009) about potential critical effects on water resources associated with the development of gas extraction from the Marcellus Shale of the Hamilton Group (Ver Straeten and others, 1994). Since that time, (1) the extraction process has evolved, (2) environmental awareness related to high-volume hydraulic fracturing process has increased, (3) state regulations concerning gas well drilling have been modified, and (4) the practices used by industry to obtain, transport, recover, treat, recycle, and ultimately dispose of the spent fluids and solid waste materials have evolved. This report updates and expands on Fact Sheet 2009

    The GETSI project, funded by NSF TUES, is developing and disseminating teaching and learning materials that feature geodesy data applied to critical societal issues such as climate change, water resource management, and natural hazards (serc.carleton.edu/getsi). It is collaborative between UNAVCO (NSF's geodetic facility), Mt San Antonio College, and Indiana University. GETSI was initiated after requests by geoscience faculty for geodetic teaching resources for introductory and majors-level students. Full modules take two weeks but module subsets can also be used. Modules are developed and tested by two co-authors and also tested in a third classroom. GETSI is working in partnership with the Science Education Resource Center's (SERC) InTeGrate project on the development, assessment, and dissemination to ensure compatibility with the growing number of resources for geoscience education. Two GETSI modules are being published in October 2015. "Ice mass and sea level changes" includes geodetic data from GRACE, satellite altimetry, and GPS time series. "Imaging Active Tectonics" has students analyzing InSAR and LiDAR data to assess infrastructure earthquake vulnerability. Another three modules are in testing during fall 2015 and will be published in 2016. "Surface process hazards" investigates mass wasting hazard and risk using LiDAR data. "Water resources and geodesy" uses GRACE, vertical GPS, and reflection GPS data to have students investigating droughts in California and the High Great Plains. "GPS, strain, and earthquakes" helps students learn about infinitesimal and coseismic strain through analysis of horizontal GPS data and includes an extension module on the Napa 2014 earthquake. In addition to teaching resources, the GETSI project is compiling recommendations on successful development of geodesy curricula. The chief recommendations so far are the critical importance of including scientific experts in the authorship team and investing significant resources in

  11. Pulse reshaping in photonic crystal waveguides and microcavities with Kerr nonlinearity: Critical issues for all-optical switching

    2005-01-01

    We delineate critical issues for 'controlling light with light' in photonic crystal (PC) waveguides coupled to Kerr-nonlinear microresonators. These arise from (a) fundamental trade-off between switching speed and switching intensity threshold inherent in high-quality Q-factor cavities and (b) the dynamical nonlinear oscillation of such cavities in response to incident light pulses. Using finite-difference time-domain simulations of electromagnetic pulse propagation, we consider both (i) a nonlinear Fabry-Perot microresonator (embedded within a PC waveguide) exhibiting a narrow transmission resonance and (ii) a nonlinear point defect (side-coupled to a PC waveguide) exhibiting a narrow reflection spectrum. We describe self-induced switching from transmission to reflection induced by pulse intensity tuning as well as control of pulse transmission induced by the secondary, continuous (cw) laser field propagating through the same PC waveguide. For the Fabry-Perot microresonator, a well-defined self-switching threshold is obtained. However, this is accompanied by considerable temporal and spectral distortion of the pulse caused by the oscillatory nonlinear response of the microresonator. When the quality factor of the microresonator is increased, the switching intensity threshold can be lowered but the pulse transit (switching) time and the pulse distortion are increased. For the side-coupled microresonator, a gradual (not sharp) self-switching behavior as a function of incident intensity is obtained. For both the Fabry-Perot and side-coupled nonlinear microresonators, control of pulse transmission can be achieved by means of a secondary cw laser field. The cw power required for switching with realistic Kerr nonlinearities is in excess of 1 W/μm 2 and may cause optical damage to the semiconducting PC backbone. Both instantaneous and noninstantaneous Kerr-response models are considered. Our results underscore the limitations and trade-offs inherent in the possible

  12. The Inclusion Conundrum: A Critical Account of Youth and Gender Issues Within and Beyond Sport for Development and Peace Interventions

    Full Text Available The sport for development and peace (SDP sector is made up of various development-focused policies and programs that seek to engage, stabilise, empower and create social and economic change. SDP projects, most often run by non-governmental organisations (NGOs, have been implemented in regions enduring physical conflicts, health pandemics, major gender divisions and other social crises that have a great impact on youth. In this context, sport has been accorded the difficult task of facilitating greater access for marginal, vulnerable or community groups whilst positively contributing to the attainment of diverse development objectives. While the ‘where’ and ‘why’ of SDP has been largely accounted for, the attention in this article is on the ‘who’ of SDP in relation to the notion of inclusion. Drawing on extensive research conducted in Jamaica, Kosovo, Rwanda and Sri Lanka, the idea of SDP as an inclusionary practice is critically investigated. While SDP may ‘give voice’ to participants, especially to individuals with athletic ability or sporting interests, the extent to which this creates social contexts that are fundamentally inclusive remains open to discussion. In this sense, while targeting populations, groups or individuals remains an attractive strategy to achieve specific goals, for example youth empowerment or gender equality, empirical assessments complicate the presumption that SDP programming leads to inclusion, particularly at a larger societal level. The article considers a matrix of inclusion criteria, potential outcomes, and the tensions arising between targeted SDP programming and the often-exclusionary dimensions of sport more broadly, with a focus on youth and gender issues.

  16. Magnetic Fusion Energy Plasma Interactive and High Heat Flux Components: Volume 5, Technical assessment of critical issues in the steady state operation of fusion confinement devices

    Energy Technology Data Exchange (ETDEWEB)

    1988-01-01

    Critical issues for the steady state operation of plasma confinement devices exist in both the physics and technology fields of fusion research. Due to the wide range and number of these issues, this technical assessment has focused on the crucial issues associated with the plasma physics and the plasma interactive components. The document provides information on the problem areas that affect the design and operation of a steady state ETR or ITER type confinement device. It discusses both tokamaks and alternative concepts, and provides a survey of existing and planned confinement machines and laboratory facilities that can address the identified issues. A universal definition of steady state operation is difficult to obtain. From a physics point of view, steady state is generally achieved when the time derivatives approach zero and the operation time greatly exceeds the characteristic time constants of the device. Steady state operation for materials depends on whether thermal stress, creep, fatigue, radiation damage, or power removal are being discussed. For erosion issues, the fluence and availability of the machine for continuous operation are important, assuming that transient events such as disruptions do not limit the component lifetimes. The panel suggests, in general terms, that steady state requires plasma operation from 100 to 1000 seconds and an availability of more than a few percent, which is similar to the expectations for an ETR type device. The assessment of critical issues for steady state operation is divided into four sections: physics issues; technology issues; issues in alternative concepts; and devices and laboratory facilities that can address these problems.

  19. Criticality safety issues associated with the introduction of low void reactivity fuel in the Bruce reactors - a management and technical overview

    2004-01-01

    The concept of criticality for operating reactor staff, particularly in a natural uranium-fuelled reactor, is relatively benign - the reactor is controlled at the critical condition by the regulating system. That is, issues related to criticality exist only within the reactor, in a set of carefully managed circumstances. With the introduction of enriched Low Void Reactivity Fuel (LVRF) into this operating environment comes a new 'concept of criticality', one which, although physically the same, cannot be treated in the same fashion. It may be the case that criticality can be achieved outside the reactor, albeit with a set of very pessimistic assumptions. Such 'inadvertent criticality' outside the reactor, should it occur, cannot be controlled. The consequences of such an inadvertent criticality could have far-reaching effects, not only in terms of severe health effects to those nearby, but also in terms of the negative impact on Bruce Power, and the Canadian nuclear industry in general. Thus the introduction of LVRF in the Bruce B reactors, and therefore the introduction of this new hazard, inadvertent criticality, warrants the development of a governance structure for its management. Such a program will consist of various elements, including the establishment of a framework to administer the criticality safety program, analytical assessment to support the process design, the development of operational procedures, the development of enhanced emergency procedures if necessary, and the implementation of a criticality safety training program. The entire package must be sufficient to demonstrate to station management, and the regulator, that the criticality safety risks associated with the implementation of enriched fuel have been properly evaluated, and that all necessary steps have been taken to effectively manage these risks. A well-founded Criticality Safety Program will offer such assurance. In this paper, we describe the establishment of a Criticality Safety

    At 10:30 am, September 30th, 1999, a criticality accident occurred in a conversion building of a uranium processing plant in Tokai, Ibaraki prefecture. 69 people including 3 workers who then worked at the building, 3 fire fighters who dispatched to rescue them were exposed to the radiation. People with a 350 m-radius of the site were recommended to evacuate themselves from the region to a temporarily prepared evacuation center. And about one hundred thousand people within a 10 km-radius were also advised to stay inside of their home. Nuclear Safety Commission's Accident Investigation Committee is investigating causes of this accident and have been revealing that deviation from government-authorized processing method and negligence of its illegal procedure had contributed to the accident. The influence of this accident is expanding not only to the plant operating company, local people but also to Japanese nuclear power policy, the whole nuclear industry in Japan. Especially pervasion of 'Safety Culture' is strongly being required. This report analyses latent factors of some human behavior directly contributing to the criticality accident. It also mentions that 4 critical points on the poor climate for safety in the work place, the inadequate safety management, the unsuitable equipment and the production-biased company's policy are the latent factors of this accident. It also finds that the poor climate and the production-biased policy are the most important factors. It can be said that some people directly or indirectly having caused the accident are the victims of them. (author)

    Undertaking research studies in the field of mental health is essential in mental health nursing. Qualitative research methodologies enable human experiences to become visible and recognize the importance of lived experiences. This paper argues that involving people with schizophrenia in research is critical to promote their health and well-being. The quality of qualitative research needs scrutinizing according to methodological issues such as trustworthiness and ethical standards that are a fundamental part of qualitative research and nursing curricula. The aim of this study was to critically review recent qualitative studies involving people with severe and persistent mental illness such as schizophrenia and other psychotic conditions, regarding descriptions of ethical and methodological issues in data collection and analysis. A search for relevant papers was conducted in three electronic databases, in December 2016. Fifteen qualitative interview studies were included and reviewed regarding methodological issues related to ethics, and data collection and analysis. The results revealed insufficient descriptions of methodology regarding ethical considerations and issues related to recruitment and sampling in qualitative interview studies with individuals with severe mental illness, putting trustworthiness at risk despite detailed descriptions of data analysis. Knowledge from the perspective of individuals with their own experience of mental illness is essential. Issues regarding sampling and trustworthiness in qualitative studies involving people with severe mental illness are vital to counteract the stigmatization of mental illness.

    To the extent that demand response represents an intentional electricity usage adjustment to price changes or incentive payments, consumers who exhibit more-variable load patterns on normal days may be capable of altering their loads more significantly in response to dynamic pricing plans. This study investigates the variation in the pre-enrollment load patterns of Korean commercial and industrial electricity customers and their impact on event-day loads during a critical peak pricing experiment in the winter of 2013. Contrary to conventional approaches to profiling electricity loads, this study proposes a new clustering technique based on variability indices that collectively represent the potential demand–response resource that these customers would supply. Our analysis reveals that variability in pre-enrollment load patterns does indeed have great predictive power for estimating their impact on demand–response loads. Customers in relatively low-variability clusters provided limited or no response, whereas customers in relatively high-variability clusters consistently presented large load impacts, accounting for most of the program-level peak reductions. This study suggests that dynamic pricing programs themselves may not offer adequate motivation for meaningful adjustments in load patterns, particularly for customers in low-variability clusters. - Highlights: • A method of clustering customers by variability indices is developed. • Customers in high-variability clusters provide substantial peak reductions. • Low-variability clusters exhibit limited reductions. • For low-variability customers, alternative policy instruments is well advised. • A model of discerning customer's demand response potential is suggested.

    This critical review presents several aspects related to the use of copper as a main component in brake pads in road vehicles. The compositions of these materials are attracting increasing interest and concern due to the relative contribution of wear products to particulate matter emissions in the environment as a result of braking action even though there has been a reduction in exhaust products from internal combustion engines. We review the data on the main wear mechanisms in brake systems and highlight the positive role of copper. However, similar to other heavy metal emissions, even the release of copper into the atmosphere may have important environmental and health effects. Thus, several replacement strategies are being pursued, and the positive and negative features will be critically reviewed. Additionally, the future perspectives in materials development will be discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2013-01-01

    The Fukushima Daiichi nuclear power plant accident on March 11, 2011 had a large impact both in and outside Japan, and is not yet concluded. After Tokyo Electric Power Co.'s (TEPCO's) Fukushima accident, electric power suppliers have taken measures to respond in the event that the same state of emergency occurs - deploying mobile generators, temporary pumps and hoses, and training employees in the use of this equipment. However, it is not only the “hard” problems including the design of equipment, but the “soft” problems such as organization and safety culture that have been highlighted as key contributors in this accident. Although a number of organizations have undertaken factor analysis of the accident and proposed issues to be reviewed and measures to be taken, a systematic overview about electric power suppliers' organization and safety culture has not yet been undertaken. This study is based on three major reports: the report by the national Diet of Japan Fukushima Nuclear Accident Independent Investigation Commission (the Diet report), the report by the Investigation Committee on the Accident at Fukushima Nuclear Power Stations of Tokyo Electric Power Company (Government report), and the report by the non-government committee supported by the Rebuild Japan Initiative Foundation (Non-government report). From these reports, the sections relevant to electric power suppliers' organization and safety culture were extracted. These sections were arranged to correspond with the prerequisites for the ideal organization, and 30 issues to be reviewed by electric power suppliers were extracted using brainstorming methods. It is expected that the identified issues will become a reference for every organization concerned to work on preventive measures hereafter. (author)

    General Atomics (GA) will be submitting an application for certification to the US Nuclear Regulatory Commission (NRC) for the GA-4 and GA-9 Casks In 1992. The GA-4 and GA-9 Casks are high-capacity legal weight truck casks designed to transport light water reactor spent fuel assemblies. To maintain a capacity of four pressurized-water-reactor (PWR) spent fuel assemblies, the GA-4 Cask uses burnup credit as part of the criticality control for initial enrichments over 3.0 wt% U-235. Using the US Department of Energy (DOE) Burnup Credit Program as a basis, GA has performed burnup credit analysis which is included in the Safety Analysis Report for Packaging (SARP). The GA-9 Cask can meet the criticality safety requirements using the ''fresh fuel'' assumption. Our approach to shielding design is to optimize the GA-4 and GA-9 Cask shielding configurations for minimum weights and maximum payloads. This optimization involves the use of the most effective shielding material, square cross-section geometry with rounded corners and tapered neutron shielding sections in the non-fuel regions

    Full Text Available A educação ambiental crítica e emancipatória exige que os conhecimentos sejam apropriados, construídos, de forma dinâmica, coletiva, cooperativa, contínua, interdisciplinar, democrática e participativa, voltados para a construção de sociedades sustentáveis. Este artigo trata dos temas ambientais como temas geradores para a educação ambiental, inspirados na pedagogia Paulo Freire, para quem educar é um ato de conhecimento da realidade concreta, das situações vividas, um processo de aproximação crítica da própria realidade: compreender, refletir, criticar e agir são as ações pedagógicas pretendidas. Os temas geradores são, portanto, estratégias metodológicas de um processo de conscientização da realidade opressora vivida nas sociedades desiguais; são o ponto de partida para o processo de construção da descoberta, e, por emergir do saber popular, os temas geradores são extraídos da prática de vida dos educandos, substituindo os conteúdos tradicionais e buscados através da pesquisa do universo dos educandos. O caráter político da pedagogia freireana faz-se presente, de forma radical, nos temas geradores, isto é, temas geradores só são geradores de ação-reflexão-ação se forem carregados de conteúdos sociais e políticos com significado concreto para a vida dos educandos. Assim, as propostas educativas ambientais conscientizadoras podem tomar os temas ambientais locais como temas geradores desta ação conscientizadora, desde que estes temas contenham conteúdos socioambientais significativos para os educandos e sejam definidos coletiva e participativamente.The emancipating and critical environmental education demands that knowledge must be adequate, build up in a dynamic, collective, cooperating, continuous, interdisciplinary, democratic and participating way directed to the construction of self-maintaining societies.

    Full Text Available The ethical and social implications of data mining, algorithmic curation and automation in the context of social media have been of heightened concern for a range of researchers with interests in digital media in recent years, with particular concerns about privacy arising in the context of mobile and locative media. Despite their wide adoption and economic importance, mobile dating apps have received little scholarly attention from this perspective – but they are intense sites of data generation, algorithmic processing, and cross-platform data-sharing; bound up with competing cultures of production, exploitation and use. In this paper, we describe the ways various forms of data are incorporated into, and emerge from, hook-up apps’ business logics, socio-technical arrangements, and cultures of use to produce multiple and intersecting data cultures . We propose a multi-layered research agenda for critical and empirical inquiry into this field, and suggest appropriate conceptual and methodological frameworks for exploring the social and political challenges of data cultures.

    Full Text Available Studies have shown that the quality of outcome in Nigerian secondary schools is declining at an alarming rate due to shortage of required resources as well as leadership challenges. The challenges have been observed to be as a result of lack of mentoring which is not a common practice in school management in Nigeria. Consequently, this study investigated the extent to which mentoring as a strategy for administrators' succession plan impacts on the performance of their duties in public and private secondary schools in Lagos, Nigeria. The study adopted the descriptive survey design and administered a 25-item self-constructed questionnaire on participants. A total of 530 participants were randomly selected from the population of 4,350 senior teachers. The Participants were drawn from 145 secondary schools (91 public and 54 registered private in Education District IV of Lagos State. The findings showed that mentoring has significant impact on administrators' succession planning and that succession planning does not significantly differ in public and private secondary schools in Lagos State. The study concluded that leadership development is a critical factor in secondary school effectiveness and efficiency. Therefore, serving administrators as well as prospective administrators should be regularly evaluated to determine their training needs at different career stages. There should also be mentoring related policies to enhance the managerial skills, sense of competence and effectiveness of the prospective administrators.

    To solicit input from registered nurse members of the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) on critical considerations for review and revision of existing nurse staffing guidelines. Thematic analysis of responses to a cross-sectional on-line survey question: "Please give the staffing task force your input on what they should consider in the development of recommendations for staffing of perinatal units." Members of AWHONN (N = 884). Descriptions of staffing concerns that should be considered when evaluating and revising existing perinatal nurse staffing guidelines. Consistent themes identified included the need for revision of nurse staffing guidelines due to requirements for safe care, increases in patient acuity and complexity, invisibility of the fetus and newborn as separate and distinct patients, difficulties in providing comprehensive care during labor and for mother-baby couplets under current conditions, challenges in staffing small volume units, and the negative effect of inadequate staffing on nurse satisfaction and retention. Participants overwhelmingly indicated current nurse staffing guidelines were inadequate to meet the needs of contemporary perinatal clinical practice and required revision based on significant changes that had occurred since 1983 when the original staffing guidelines were published. © 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    The two-phase mixture model developed by Baer and Nunziato (BN) to study the deflagration-to-detonation transition (DDT) in granular explosives is critically reviewed. The continuum-mixture theory foundation of the model is examined, with particular attention paid to the manner in which its constitutive functions are formulated. Connections between the mechanical and energetic phenomena occurring at the scales of the grains, and their manifestations on the continuum averaged scale, are explored. The nature and extent of approximations inherent in formulating the constitutive terms, and their domain of applicability, are clarified. Deficiencies and inconsistencies in the derivation are cited, and improvements suggested. It is emphasized that the entropy inequality constrains but does not uniquely determine the phase interaction terms. The resulting flexibility is exploited to suggest improved forms for the phase interactions. These improved forms better treat the energy associated with the dynamic compaction of the bed and the single-phase limits of the model. Companion papers of this study [Kapila et al., Phys. Fluids 9, 3885 (1997); Kapila et al., in preparation; Son et al., in preparation] examine simpler, reduced models, in which the fine scales of velocity and pressure disequilibrium between the phases allow the corresponding relaxation zones to be treated as discontinuities that need not be resolved in a numerical computation. copyright 1999 American Institute of Physics

    Full Text Available During the International Year of Planet Earth (2007-2009, the Department of Earth Sciences of Turin University and a local Museum of Natural History promoted a project entitled, Understanding how the Earth works: from local situations to global processes. In this context, two geothematic exhibitions on the Cape Verde Archipelago were designed and staged in local museums. The exhibition called Getting to know a volcano in order to live with it was the subject of action research that involved the design of interactive activities and the analysis of data collected during guided tours conducted with students of different ages. This study allowed the demonstration of the effectiveness of teaching strategies in which relevant Earth sciences topics are proposed, like risk and sustainable development, thus stimulating debate among the students. This approach enhances the cultural experience of individuals by sharing it with other people. The aim was to widen their awareness of the cultural value of the territory, and to stimulate a new critical way of thinking about the Earth sciences. These didactic tools were further developed when they were proposed and pursued by experienced museum guides and teachers, who were able to involve not only institutions (museums and schools in the knowledge construction process, but also families, relatives and the local community.

    Dementia and Alzheimer's disease (AD) is considered a major public health challenge in this decade and in the future. Early detection of AD through appropriate screening tools would be valuable approach in facing the burden of disease specifically in developing societies with insufficient resources. Selecting a screening tool which is non-expensive, non-invasive and implementable by trained primary healthcare providers is the first and probably the most important step in detecting high risk individuals. The goal of this review is to address the key issues in assessment tools in developing countries with a high level of illiteracy. We set about a review on literature on the subject of cognitive function assessment among minorities, people with low or no education, and people who live in underdeveloped societies. We also reviewed the studies on validation of such tests in a new society. The most popular assessment tools are more or less biased by the level of education; not all of them are useful for any type of dementia as they assess only some domains of cognitive function. Even though people with lower level of education have a higher rate of developing dementia, cognitive function cannot be accurately assessed because of limitations of current available tools. It is strongly suggested that special attention be paid to assess them by functional scales and activity daily living scales. For a more efficient assessment, cognitive tests can also benefit from illustrative questions, proverbs, metaphors, traditions, religious rituals and historical events.

    The new era of designing in architecture and civil engineering applications lies in the Building Information Modeling (BIM) approach, based on a 3D geometric model including a 3D database. This is easier for new constructions whereas, when dealing with existing buildings, the creation of the BIM is based on the accurate knowledge of the as-built construction. Such a condition is allowed by a 3D survey, often carried out with laser scanning technology or modern photogrammetry, which are able to guarantee an adequate points cloud in terms of resolution and completeness by balancing both time consuming and costs with respect to the request of final accuracy. The BIM approach for existing buildings and even more for historical buildings is not yet a well known and deeply discussed process. There are still several choices to be addressed in the process from the survey to the model and critical issues to be discussed in the modeling step, particularly when dealing with unconventional elements such as deformed geometries or historical elements. The paper describes a comprehensive workflow that goes through the survey and the modeling, allowing to focus on critical issues and key points to obtain a reliable BIM of an existing monument. The case study employed to illustrate the workflow is the Basilica of St. Stefano in Bologna (Italy), a large monumental complex with great religious, historical and architectural assets.

    Organizational changes focused on process orientation are taking place among Swedish nuclear power plants, aiming at improving the operation. The Swedish Nuclear Power Inspectorate has identified a need for increased knowledge within the area for its regulatory activities. In order to analyze what process orientation imply for nuclear power plant safety a number of questions must be asked: 1. How is safety in nuclear power production created currently? What significance does the functional organization play? 2. How can organizational forms be analysed? What consequences does quality management have for work and for the enterprise? 3. Why should nuclear power plants be process oriented? Who are the customers and what are their customer values? Which customers are expected to contribute from process orientation? 4. What can one learn from process orientation in other safety critical systems? What is the effect on those features that currently create safety? 5. Could customer values increase for one customer without decreasing for other customers? What is the relationship between economic and safety interests from an increased process orientation? The deregulation of the electricity market have caused an interest in increased economic efficiency, which is the motivation for the interest in process orientation. among other means. It is the nuclear power plants' owners and the distributors (often the same corporations) that have the strongest interest in process orientation. If the functional organization and associated practices are decomposed, the prerequisites of the risk management regime changes, perhaps deteriorating its functionality. When nuclear power operators consider the introduction of process orientation, the Nuclear Power Inspectorate should require that 1. The operators perform a risk analysis beforehand concerning the potential consequences that process orientation might convey: the analysis should contain a model specifying how safety is currently

    health care was independently associated with adverse self-reported health, adjusting for discrimination in other public accommodations settings. Overall, 65% of respondents reported public accommodations discrimination in the past 12 months. The 5 most prevalent discrimination settings were transportation (36%), retail (28%), restaurants (26%), public gatherings (25%), and health care (24%). Public accommodations discrimination in the past 12 months in health care settings was independently associated with a 31% to 81% increased risk of adverse emotional and physical symptoms and a 2-fold to 3-fold increased risk of postponement of needed care when sick or injured and of preventive or routine health care, adjusting for discrimination in other public accommodations settings (which also conferred an additional 20% to 77% risk per discrimination setting endorsed). Discrimination in public accommodations is common and is associated with adverse health outcomes among transgender and gender-nonconforming adults in Massachusetts.

  6. Teachers' understandings and enactments of social and environmental justice issues in the classroom: What's "critical" in the manufacturing of road-smart squirrels?

    Science.gov (United States)

    Sammel, Alison J.

    How do five new teachers understand and enact counter-hegemonic pedagogies in their own classes? This study developed from this question. The question arose as I taught critical environmental education, a counter-hegemonic pedagogy, to preservice science teachers. I encouraged the exploration of social and environmental injustices and how they function to reproduce dominant economic agendas. To understand how five teachers, in the second year of their practice and my former students, made sense of the critical environmental education I taught them, I used Gadamer's hermeneutic phenomenology as my research frame. Gadamer argues that meaning develops through dialogue, so data collection occurred mainly through lively research conversations over leisurely dinners. As practicing teachers, the six of us jointly explored taken-for-granted meanings and actions in our everyday pedagogical experiences. In these conversations we made meaning (the hermeneutic aspect) of the lived experiences (phenomenological aspect) of incorporating critical environmental education into our practices. This led me to a deeper understanding and increased awareness of how science education reform agendas have influenced and shaped our individual science pedagogies. The analytic lens of critical education showed that these teachers were strongly influenced by the dominant science reform agenda. Regardless of the science curriculum, or the strong social and environmental beliefs some of these teachers held, they did not perceive the teaching of the social and environmental justice issues to be 'critical' or 'their job.' They demonstrated a belief that it was 'critical' to teach well-defined, "hard science" facts. Student success, hence teacher success, involved playing the academic game well and gaining long-term financial security. Re/viewing the data stories through the additional analytic lens of feminist poststructuralism, I saw how dominant discourse constructs the identity of teachers

    The objective of this paper is to assess the near term (one-to-five-year) needs of domestic and foreign commercial suppliers of radiochemicals and radiopharmaceuticals for electromagnetically separated stable isotopes. Only isotopes purchased to make products for sale and profit are considered in this assessment. Radiopharmaceuticals produced from enriched stable isotopes supplied by the Calutron facility at ORNL are used in about 600,000 medical procedures each year in the United States. A temporary or permanent disruption of the supply of stable isotopes to the domestic radiopharmaceutical industry could curtail, if not eliminate, the use of such diagnostic procedures as the thallium heart scan, the gallium cancer scan, the gallium abscess scan, and the low-radiation-dose thyroid scan. The word could in the preceding sentence is underlined because an alternative source of enriched stable isotopes does exist in the USSR. Alternative starting materials could, in theory, eventually be developed for both the thallium and gallium scans. The development of a new technology for these purposes, however, would take at least five years and would be expensive. Hence, any disruption of the supply of enriched isotopes from ORNL and the resulting unavailability of critical nuclear medicine procedures would have a dramatic negative effect on the level of health care in the United States

    The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories.

    To critically examine the conceptual, methodological and validity issues with the "caring cultures" construct. Post the Francis Report, "caring cultures" and alternative terminology such as "culture/s of care/caring/compassionate care" have gained prominence in the literature, especially within a UK policy context. However, in order to understand the value these "caring cultures" hold in terms of clinical practice, the concept itself first needs to be understood. A discussion and critical examination of the concept of "caring cultures" and associated terminology. Grey literature, database, library and reference list searches were conducted. It is implied that "caring cultures" influence patient care. However, evidence which verifies this assertion is limited. In this article, the concept of "caring cultures" is deconstructed and its validity explored. An alternative to "caring cultures" is proposed in terms of research, whereby the concept of culture is instead explored in detail, on a microsystem level, using appropriate methodology. The concept of "caring cultures", although attractive in terms of its apparent simplicity, is not considered the most useful nor appropriate phrases in terms of advancing research. Instead, research which examines the established concept of "culture" in relation to outcomes such as patient care, doing so with an appropriate methodology, is viewed as a more suitable alternative. Clarifying concepts and terminology relating to "caring cultures" is essential for research to progress and the impact of culture on clinical practice to be better understood. © 2017 John Wiley & Sons Ltd.

  12. Critical issues in overlay metrology

    International Nuclear Information System (INIS)

    Sullivan, Neal T.

    2001-01-01

    In this paper, following an overview of overlay metrology, the difficult relationship of overlay with device performance and yield is discussed and supported with several examples. This is followed by a discussion of the impending collision of metrology equipment performance and 'real' process tolerances for sub 0.18 um technologies. This convergence of tolerance and performance is demonstrated to lead to the current emergence of real-time overlay modeling in a feed-forward/feedback process environment and the associated metrology/sampling implications. This modeling takes advantage of the wealth of understanding concerning the systematic behavior of overlay registration errors. Finally, the impact of new process technologies (RET, OAI, CPSM, CMP, and etc.) on the measurement target is discussed and shown to de-stabilize overlay performance on standard overlay measurement target designs

  14. A critical assessment of marine aquarist biodiversity data and commercial aquaculture: identifying gaps in culture initiatives to inform local fisheries managers.

    Directory of Open Access Journals (Sweden)

    Joanna M Murray

    Full Text Available It is widely accepted that if well managed, the marine aquarium trade could provide socio-economic stability to local communities while incentivising the maintenance of coral reefs. However, the trade has also been implicated as having potentially widespread environmental impacts that has in part driven developments in aquaculture to relieve wild collection pressures. This study investigates the biodiversity in hobbyist aquaria (using an online survey and those species currently available from an aquaculture source (commercial data and hobbyist initiatives in the context of a traffic light system to highlight gaps in aquaculture effort and identify groups that require fisheries assessments. Two hundred and sixty nine species including clown fish, damsels, dotty backs, angelfish, gobies, sea horses and blennies, have reported breeding successes by hobbyists, a pattern mirrored by the European and US commercial organisations. However, there is a mismatch (high demand and low/non-existent aquaculture for a number of groups including tangs, starfish, anemones and hermit crabs, which we recommend are priority candidates for local stock assessments. Hobbyist perception towards the concept of a sustainable aquarium trade is also explored with results demonstrating that only 40% of respondents were in agreement with industry and scientists who believe the trade could be an exemplar of a sustainable use of coral reefs. We believe that a more transparent evidence base, including the publication of the species collected and cultured, will go some way to align the concept of a sustainable trade across industry stakeholders and better inform the hobbyist when purchasing their aquaria stock. We conclude by proposing that a certification scheme established with government support is the most effective way to move towards a self-regulating industry. It would prevent industry "greenwashing" from multiple certification schemes, alleviate conservation concerns

    This longitudinal study explored the effects of a Cooperation-driven Socioscientific Issue (CDSSI) intervention on junior high school students' perceptions of critical thinking (CT) and self-regulation (SR) in Taiwan. Forty-nine grade 7 students were randomly selected as an experimental group (EG) to attend a 3-semester 72-hour intervention; while another 49 grade 7 students from the same school were randomly selected as the comparison group (CG). All participants completed a 4-wave student questionnaire to assess their perceptions of CT and SR. In addition, 8 target students from the EG with the lowest scores on either CT or SR were purposefully recruited for weekly observation. These target students and their teachers were interviewed one month after the intervention in each semester. Analyses of covariance and paired-wise t-tests revealed that the EG students' perceptions of CT and SR in learning science were improved during the study and were significantly better than their counterparts' at the end of the study. Systematic interview and classroom observation results were consistent with the quantitative findings. This study adds empirical evidence and provides insights into how CDSSI can be integrated into planning and implementing effective pedagogical strategies aimed at increasing students' perceptions of CT and SR in learning science.

    This article investigates the performance of 2 commercial real-time polymerase chain reaction (PCR) assays, MycAssay™ Aspergillus (Myc(Asp)Assay) and MycAssay™ Pneumocystis (Myc(PCP)Assay), on the ABI 7300 platform for the detection of Aspergillus (Asp) or Pneumocystis jirovecii (Pj) DNA in bronchoalveolar lavage (BAL) samples from 20 patients. Operationally, patients enrolled were clustered into 3 groups: invasive aspergillosis group (IA, 7 patients), Pj pneumonia group (PCP, 8 patients), and negative control group (5 patients). All the IA patients were Myc(Asp)Assay positive, whereas 12 non-IA patients returned negative PCR results. Furthermore, 7 of 8 PCP patients were Myc(PCP)Assay positive, while 9 non-PCP patients were PCR negative. In conclusion, these data provide an early indication of the effectiveness of both the Myc(Asp)Assay and Myc(PCP)Assay on the ABI 7300 platform for the detection of either Asp or Pj DNA in BAL from patients with deep fungal infections.

    1981-01-01

    Lawrence Livermore National Laboratory (LLNL) is developing seismic and wind hazard models for the US Department of Energy (DOE). The work is part of a three-phase effort to establish building design criteria developed with a uniform methodology for seismic and wind hazards at the various DOE sites throughout the United States. In Phase 1, LLNL gathered information on the sites and their critical facilities, including nuclear reactors, fuel-reprocessing plants, high-level waste storage and treatment facilities, and special nuclear material facilities. Phase 2 - development of seismic and wind hazard models - is discussed in this paper, which summarizes the methodologies used by seismic and extreme-wind experts and gives sample hazard curves for the first sites to be modeled. These hazard models express the annual probability that the site will experience an earthquake (or windspeed) greater than some specified magnitude. In the final phase, the DOE will use the hazards models and LLNL-recommended uniform design criteria to evaluate critical facilities. The methodology presented in this paper also was used for a related LLNL study - involving the seismic assessment of six commercial plutonium fabrication plants licensed by the US Nuclear Regulatory Commission (NRC). Details and results of this reassessment are documented in reference

    1991-01-01

    A plan was initiated in 1988 to commercialize the Numerical Evaluation of Stochastic Structures Under Stress (NESSUS) probabilistic structural analysis software. The goal of the on-going commercialization effort is to begin the transfer of Probabilistic Structural Analysis Method (PSAM) developed technology into industry and to develop additional funding resources in the general area of structural reliability. The commercialization effort is summarized. The SwRI NESSUS Software System is a general purpose probabilistic finite element computer program using state of the art methods for predicting stochastic structural response due to random loads, material properties, part geometry, and boundary conditions. NESSUS can be used to assess structural reliability, to compute probability of failure, to rank the input random variables by importance, and to provide a more cost effective design than traditional methods. The goal is to develop a general probabilistic structural analysis methodology to assist in the certification of critical components in the next generation Space Shuttle Main Engine.

  11. Fact versus fiction. The socio-economic benefits to be found in teaching critical thinking skills on nuclear waste issues in public schools

    International Nuclear Information System (INIS)

    Anderson, H.

    1984-01-01

    The safe storage of radioactive wastes has been the topic of much heated debate. Many of the concerns raised demonstrate that the public is poorly informed about nuclear matters, bewildered by conflicting testimony and lacking the intellectual skills required to discriminate between statements of fact versus opinion or motive. Recently, the National Council for the Social Studies (NCSS) adopted a set of guidelines intended to encourage a stronger emphasis on urgent science-related social issues in the classroom and to provide for social studies teachers, rational and structure for the presentation of these issues. In this way, the NCSS is moving to meet the needs of the community for greater technological awareness. NCSS believes students need instruction and strategies for evaluating science-related material intelligently. As a case study in point, the topic ''Nuclear Waste: A Science Related Social Issue of Urgent Concern'' was brought before a recent NCSS national meeting. This paper discusses strategies for dealing with nuclear waste issues in the classroom and the potential socio-economic benefits to be found in dispelling myths surrounding nuclear issues

    Tom G. K. Bryce and Stephen P. Day's (2013) original article on scepticism and doubt in science education explores the context of citizens' attitudes towards the complexities and uncertainties of global issues, namely global warming. This response aims to stimulate reflection on some of the implicit assumptions underpinning the relationships between science, technology and the public. I argue that an underestimation of the political and ethical dimensions of science and technology limits the possibilities for education to set the agenda for citizens' participation in science and technological matters. Drawing on Sheila Jasanoff's model of co-production, this paper proposes a radical re-affirmation of the aims and purposes of science education to embrace a multiplicity of disciplines, narratives and ways of knowing in science, technology and society issues.

    Price, R.O.

    1992-01-01

    Southern California's heavy reliance on petroleum-fueled transportation has resulted in significant air pollution problems within the south Coast Air Basin (Basin) which stem directly from this near total dependence on fossil fuels. To deal with this pressing issue, recently enacted state legislation has proposed mandatory introduction of clean alternative fuels into ground transportation fleets operating within this area. The commercial air transportation sector, however, also exerts a significant impact on regional air quality which may exceed emission gains achieved in the ground transportation sector. This paper addresses the potential, through the implementation of methanol as a commercial aviation fuel, to improve regional air quality within the Basin and the need to flight test and demonstrate methanol as an environmentally preferable fuel in aircraft turbine engines

    Balachandra, P.; Kristle Nathan, Hippu Salk; Reddy, B. Sudhakara

    2010-01-01

    Commercialization efforts to diffuse sustainable energy technologies (SETs) have so far remained as the biggest challenge in the field of renewable energy and energy efficiency. Limited success of diffusion through government driven pathways urges the need for market based approaches. This paper reviews the existing state of commercialization of SETs in the backdrop of the basic theory of technology diffusion. The different SETs in India are positioned in the technology diffusion map to reflect their slow state of commercialization. The dynamics of SET market is analysed to identify the issues, barriers and stakeholders in the process of SET commercialization. By upgrading the 'potential adopters' to 'techno-entrepreneurs', the study presents the mechanisms for adopting a private sector driven 'business model' approach for successful diffusion of SETs. This is expected to integrate the processes of market transformation and entrepreneurship development with innovative regulatory, marketing, financing, incentive and delivery mechanisms leading to SET commercialization.

    2015-05-01

    As a part of the 6th IWGT, an expert working group on the comet assay evaluated critical topics related to the use of the in vivo comet assay in regulatory genotoxicity testing. The areas covered were: identification of the domain of applicability and regulatory acceptance, identification of critical parameters of the protocol and attempts to standardize the assay, experience with combination and integration with other in vivo studies, demonstration of laboratory proficiency, sensitivity and power of the protocol used, use of different tissues, freezing of samples, and choice of appropriate measures of cytotoxicity. The standard protocol detects various types of DNA lesions but it does not detect all types of DNA damage. Modifications of the standard protocol may be used to detect additional types of specific DNA damage (e.g., cross-links, bulky adducts, oxidized bases). In addition, the working group identified critical parameters that should be carefully controlled and described in detail in every published study protocol. In vivo comet assay results are more reliable if they were obtained in laboratories that have demonstrated proficiency. This includes demonstration of adequate response to vehicle controls and an adequate response to a positive control for each tissue being examined. There was a general agreement that freezing of samples is an option but more data are needed in order to establish generally accepted protocols. With regard to tissue toxicity, the working group concluded that cytotoxicity could be a confounder of comet results. It is recommended to look at multiple parameters such as histopathological observations, organ-specific clinical chemistry as well as indicators of tissue inflammation to decide whether compound-specific toxicity might influence the result. The expert working group concluded that the alkaline in vivo comet assay is a mature test for the evaluation of genotoxicity and can be recommended to regulatory agencies for use

    To critically examine surveillance practices of health visitors (HV) in the UK and public health nurses (PHNs) in Canada. The practice and meaning of surveillance shifts and changes depending on the context and intent of relationships between mothers and HVs or PHNs. We present the context and practice of HVs in the UK and PHNs in Canada and provide a comprehensive literature review regarding surveillance of mothers within public health systems. We then present our critique of the meaning and practice of surveillance across different settings. Concepts from Foucault and discourse analysis are used to critically examine and discuss the meaning of surveillance. Surveillance is a complex concept that shifts meaning and is socially and institutionally constructed through relations of power. Healthcare providers need to understand the different meanings and practices associated with surveillance to effectively inform practice. Healthcare providers should be aware of how their positions of expert and privilege within healthcare systems affect relationships with mothers. A more comprehensive understanding of personal, social and institutional aspects of surveillance will provide opportunities to reflect upon and change practices that are supportive of mothers and their families. © 2017 John Wiley & Sons Ltd.

    As the Amendment of the Law for the Regulation of Nuclear Material, Nuclear Fuel Material and Reactors on an opportunity of the JCO criticality accident can be almost evaluated at a viewpoint of upgrading on effectiveness of safety regulation, it is thought to remain a large problem to rely on only enforcement of regulation due to amendment of the Law at future accident. In future, it can be also said to be important subjects to further expand a philosophy on the regulation (material regulation) focussed to hazards of nuclear material itself, not only to secure effectiveness on the multi-complementary safety regulation due to the administrative agency and the Nuclear Safety Commission but also to prepare a mechanism reflexible of a new information to the safety regulation, and to prepare a mechanism to assist adequate business execution and so forth of enterprises.

    1984-01-01

    This Working Paper Series entry presents a detailed survey of knowledge based systems. After being in a relatively dormant state for many years, only recently is Artificial Intelligence (AI) - that branch of computer science that attempts to have machines emulate intelligent behavior - accomplishing practical results. Most of these results can be attributed to the design and use of Knowledge-Based Systems, KBSs (or ecpert systems) - problem solving computer programs that can reach a level of performance comparable to that of a human expert in some specialized problem domain. These systems can act as a consultant for various requirements like medical diagnosis, military threat analysis, project risk assessment, etc. These systems possess knowledge to enable them to make intelligent desisions. They are, however, not meant to replace the human specialists in any particular domain. A critical survey of recent work in interactive KBSs is reported. A case study (MYCIN) of a KBS, a list of existing KBSs, and an introduction to the Japanese Fifth Generation Computer Project are provided as appendices. Finally, an extensive set of KBS-related references is provided at the end of the report.

    Mycobacterium bovis Bacillus Calmette-Guérin (BCG) as a live vector of recombinant bacterial vaccine is a promising system to be used. In this study, we evaluate the disrupted expression of heterologous HIV-1gp120 gene in BCG Pasteur host strain using replicative vectors pMV261 and pJH222. pJH222 carries a lysine complementing gene in BCG lysine auxotrophs. The HIV-1 gp120 gene expression was regulated by BCG hsp60 promoter (in plasmid pMV261) and Mycobacteria spp. α-antigen promoter (in plasmid pJH222). Among 14 rBCG:HIV-1gp120 (pMV261) colonies screened, 12 showed a partial deletion and two showed a complete deletion. However, deletion was not observed in all 10 rBCG:HIV-1gp120 (pJH222) colonies screened. In this study, we demonstrated that E. coli/Mycobacterial expression vectors bearing a weak promoter and lysine complementing gene in a recombinant lysine auxotroph of BCG could prevent genetic rearrangements and disruption of HIV 1gp120 gene expression, a key issue for engineering Mycobacterial based vaccine vectors.

    This paper explores the range of possibilities for producing super high fields with advanced superconducting magnets. Obtaining magnetic fields greater than about 18 T at the coil in a large superconducting magnet system will require advances in many areas of magnet technology. These needs are discussed and potential solutions (advanced superconductors, structural materials and design methods) evaluated. A point design for a commercial reactor with magnetic field at the coil of 24 T and fusion power of 1800 MW is presented. Critical issues and parameters for magnet design are identified. 20 refs., 9 figs., 4 tabs

    The liability issues of radon exposure have prompted potential purchasers of vacant land for commercial/industrial development, and commercial landlords, renting large commercial buildings, to determine the radon gas levels at such sites. This paper deals with both pre-construction sites subject to freezing conditions and to large commercial structures. A correlation of radon gas levels within a commercial building and a sister pre-construction site confirms the validity of using activated charcoal canisters as a cost effective means to combating radon in large structures

The teaching of these skills is still neglected in some language classes in Brazil, be it in L1 or in L2 classes. Thus, this paper may also serve as a resource guide for L1 and/or L2 reading and writing teachers who want to incorporate critical reading and thinking into their classes. In modern society, even in everyday life people frequently need to deal with complicated public and political issues, make decisions, and solve problems. In order to do this efficiently and effectively, citizens must be able to evaluate critically what they see, hear, and read. Also, with the huge amount of printed material available in all areas in this age of “information explosion” it is easy to feel overwhelmed.

  1. Transitional issues

    International Nuclear Information System (INIS)

    1998-01-01

    This discussion paper, the fifth in the series developed at the IPPSO Market Design Conference, addressed the issue of the need to prevent Ontario Hydro from taking unfair advantage of independent producers and other stakeholders through activities and investments in new power generating capacity in the transitional period leading up to deregulation. The need for controls is predicated on the assumption that the short-term actions and investments of Ontario Hydro could seriously compromise the position of independent generators, and that without such controls the level playing field essential to the operation of a competitive market, does not exist. Various actual and potential actions of Ontario Hydro were discussed, all of which point to the need for strict controls over Ontario Hydro exercising its dominant market power in an unfair way. It was recommended that as a minimum, the provincial government should no longer provide guarantees for Ontario Hydro capital projects, and that Ontario Hydro be instructed to defer any investment on new or returning generating capacity until the new market is in place. Limits could also be placed on Ontario Hydro's marketing efforts to enter into contracts during the transition period, and Ontario Hydro and municipal utilities should be required to keep separate accounts of their commercial preparation, and to settle such accounts separate from ratepayer revenue

  7. Commercial nuclear power 1990

    International Nuclear Information System (INIS)

    1990-01-01

    This report presents the status at the end of 1989 and the outlook for commercial nuclear capacity and generation for all countries in the world with free market economies (FME). The report provides documentation of the US nuclear capacity and generation projections through 2030. The long-term projections of US nuclear capacity and generation are provided to the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) for use in estimating nuclear waste fund revenues and to aid in planning the disposal of nuclear waste. These projections also support the Energy Information Administration's annual report, Domestic Uranium Mining and Milling Industry: Viability Assessment, and are provided to the Organization for Economic Cooperation and Development. The foreign nuclear capacity projections are used by the DOE uranium enrichment program in assessing potential markets for future enrichment contracts. The two major sections of this report discuss US and foreign commercial nuclear power. The US section (Chapters 2 and 3) deals with (1) the status of nuclear power as of the end of 1989; (2) projections of nuclear capacity and generation at 5-year intervals from 1990 through 2030; and (3) a discussion of institutional and technical issues that affect nuclear power. The nuclear capacity projections are discussed in terms of two projection periods: the intermediate term through 2010 and the long term through 2030. A No New Orders case is presented for each of the projection periods, as well as Lower Reference and Upper Reference cases. 5 figs., 30 tabs

    For more than ten years, private industry has worked to develop a commercial human space market and to create a sustainable ISS commercial utilization customer base. Before ISS assembly was underway - and long before NASA and the international space agencies began to craft ISS commercial business terms and conditions - industry planted and nurtured the seeds of interest in exploiting human space utilization for commerce. These early initiatives have yielded the impetus and framework for industry approaches to ISS commercial utilization today and for NASA's and the International Partners' planned accommodation of private sector interests and desires on the ISS. This paper chronicles major industry initiatives for commercial ISS utilization, emphasizing successful marketing and business approaches and why these approaches have a higher likelihood of success than others. It provides an overview of individual companies' initiatives, as well as collaborative efforts that cross company lines and country borders; and it assesses the relative success of each. Rather than emphasize negative issues and barriers, this paper characterizes and prioritizes actionable success factors for industry and government to make ISS commercial utilization a sustainable reality.

    Hoff, T.; Wenger, H.J.; Keane, D.M.

    1993-01-01

    Pacific Gas and Electric Company (PG ampersand E) recently applied Demand-Side Management (DSM) evaluation techniques to photovoltaic (PV) technology to develop the concept of photovoltaics as a Demand-Side Management option (PV-DSM). The analysis demonstrated that PV-DSM has the potential to be economically attractive. Two criticisms in response to that analysis are that the assumptions of 25 year financing and a 25 year evaluation period are unrealistic. This paper responds to those criticisms and documents the mathematical relationships to calculate the value of PV-DSM from a customer's perspective. It demonstrates how regulatory and government agencies could implement policies to resolve both issues and speed PV commercialization

    2010-03-24

    The high number of divorces could partly be attributed to a lack of sexual desire in the couples linked to the prevailing sexual hyperstimulation in society. Sexual harassment on the internet and the exposition of abuse incidents in the mass media contribute to the increased numbers of child sexual abuse. Enhanced awareness among adults about the potential dangers of television and the internet, as well as psychotherapeutic treatment of abusers and their victims would be of preventative importance. Psychotherapeutic treatment of adolescents in situations of developmental "break-down" could result in a more mature sexuality contributing to fewer cases of sexual abuse and to the stabilisation of future couples on the long-term.

    2003-01-01

    The proposed Yucca Mountain repository site currently lacks rail access. The nearest mainline railroad is almost 100 miles away. Absence of rail access could result in many thousands of truck shipments of spent nuclear fuel and high-level radioactive waste. Direct rail access to the repository could significantly reduce the number of truck shipments and total shipments. The U.S. Department of Energy (DOE) identified five potential rail access corridors, ranging in length from 98 miles to 323 miles, in the Final Environmental Impact Statement (FEIS) for Yucca Mountain. The FEIS also considers an alternative to rail spur construction, heavy-haul truck (HHT) delivery of rail casks from one of three potential intermodal transfer stations. The authors examine the feasibility and cost of the five rail corridors, and DOE's alternative proposal for HHT transport. The authors also address the potential for rail shipments through the Las Vegas metropolitan area

    The TERMIS-Europe (EU) Industry committee intended to address the two main critical issues in the clinical/commercial translation of Advanced Therapeutic Medicine Products (ATMP): (1) entrepreneurial exploitation of breakthrough ideas and innovations, and (2) regulatory market approval. Since January 2012, more than 12,000 publications related to regenerative medicine and tissue engineering have been accepted for publications, reflecting the intense academic research activity in this field. The TERMIS-EU 2014 Industry Symposium provided a reflection on the management of innovation and technological breakthroughs in biotechnology first proposed to contextualize the key development milestones and constraints of allocation of financial resources, in the development life-cycle of radical innovation projects. This was illustrated with the biofuels story, sharing similarities with regenerative medicine. The transition was then ensured by an overview of the key identified challenges facing the commercialization of cell therapy products as ATMP examples. Real cases and testimonies were then provided by a palette of medical technologies and regenerative medicine companies from their commercial development of cell and gene therapy products. Although the commercial development of ATMP is still at the proof-of-concept stage due to technology risks, changing policies, changing markets, and management changes, the sector is highly dynamic with a number of explored therapeutic approaches, developed by using a large diversity of business models, both proposed by the experience, pitfalls, and successes of regenerative medicine pioneers, and adapted to the constraint resource allocation and environment in radical innovation projects.

It is clear, however, that the total generation of commercial nuclear waste does not tell the whole story, there are sizeable stockpiles of defense nuclear wastes which will impact areas such as total nuclide exposure to the biosphere and the overall economics of waste disposal. The effects of these other nuclear waste streams can be factored in as exogenous inputs. Their generation is essentially independent of nuclear power operations. The objective of this report is to assess the real-world problems associated with nuclear waste management and to design the analytical framework, as appropriate, for handling nuclear waste management issues in the International Nuclear Model. As such, some issues that are not inherently quantifiable, such as the development of environmental Impact Statements to satisfy the National Environmental Protection Act requirements, are only briefly mentioned, if at all

    1984-08-01

    The increasing use of digital imaging techniques create a need for improved methods of digital processing, communication and archiving. However, the commercial opportunity is dependent on the resolution of a number of issues. These issues include proof that digital processes are more cost effective than present techniques, implementation of information system support in the imaging activity, implementation of industry standards, conversion of analog images to digital formats, definition of clinical needs, the implications of the purchase decision and technology requirements. In spite of these obstacles, a market is emerging, served by new and existing companies, that may become a $500 million market (U.S.) by 1990 for equipment and supplies.

    Full Text Available In this comment, the author reflects on surveillance from a critical theory approach, his involvement in surveillance research and projects, and the status of the study of surveillance. The comment ascertains a lack of critical thinking about surveillance, questions the existence of something called “surveillance studies” as opposed to a critical theory of society, and reflects on issues such as Edward Snowden’s revelations, and Foucault and Marx in the context of surveillance.

  2. Toward critical bioethics.

    Science.gov (United States)

    Árnason, Vilhjálmur

    2015-04-01

    This article deals with the question as to what makes bioethics a critical discipline. It considers different senses of criticism and evaluates their strengths and weaknesses. A primary method in bioethics as a philosophical discipline is critical thinking, which implies critical evaluation of concepts, positions, and arguments. It is argued that the type of analytical criticism that restricts its critical role to critical thinking of this type often suffers from other intellectual flaws. Three examples are taken to demonstrate this: premature criticism, uncritical self-understanding of theoretical assumptions, and narrow framing of bioethical issues. Such flaws can lead both to unfair treatment of authors and to uncritical discussion of topics. In this context, the article makes use of Häyry's analysis of different rationalities in bioethical approaches and argues for the need to recognize the importance of communicative rationality for critical bioethics. A radically different critical approach in bioethics, rooted in social theory, focuses on analyses of power relations neglected in mainstream critical thinking. It is argued that, although this kind of criticism provides an important alternative in bioethics, it suffers from other shortcomings that are rooted in a lack of normative dimensions. In order to complement these approaches and counter their shortcomings, there is a need for a bioethics enlightened by critical hermeneutics. Such hermeneutic bioethics is aware of its own assumptions, places the issues in a wide context, and reflects critically on the power relations that stand in the way of understanding them. Moreover, such an approach is dialogical, which provides both a critical exercise of speech and a normative dimension implied in the free exchange of reasons and arguments. This discussion is framed by Hedgecoe's argument that critical bioethics needs four elements: to be empirically rooted, theory challenging, reflexive, and politely skeptical.

  3. Commercial nuclear power 1990

    Energy Technology Data Exchange (ETDEWEB)

    1990-09-28

    This report presents the status at the end of 1989 and the outlook for commercial nuclear capacity and generation for all countries in the world with free market economies (FME). The report provides documentation of the US nuclear capacity and generation projections through 2030. The long-term projections of US nuclear capacity and generation are provided to the US Department of Energy's (DOE) Office of Civilian Radioactive Waste Management (OCRWM) for use in estimating nuclear waste fund revenues and to aid in planning the disposal of nuclear waste. These projections also support the Energy Information Administration's annual report, Domestic Uranium Mining and Milling Industry: Viability Assessment, and are provided to the Organization for Economic Cooperation and Development. The foreign nuclear capacity projections are used by the DOE uranium enrichment program in assessing potential markets for future enrichment contracts. The two major sections of this report discuss US and foreign commercial nuclear power. The US section (Chapters 2 and 3) deals with (1) the status of nuclear power as of the end of 1989; (2) projections of nuclear capacity and generation at 5-year intervals from 1990 through 2030; and (3) a discussion of institutional and technical issues that affect nuclear power. The nuclear capacity projections are discussed in terms of two projection periods: the intermediate term through 2010 and the long term through 2030. A No New Orders case is presented for each of the projection periods, as well as Lower Reference and Upper Reference cases. 5 figs., 30 tabs.

    1994-04-29

    Commercial Buildings Characteristics 1992 presents statistics about the number, type, and size of commercial buildings in the United States as well as their energy-related characteristics. These data are collected in the Commercial Buildings Energy Consumption Survey (CBECS), a national survey of buildings in the commercial sector. The 1992 CBECS is the fifth in a series conducted since 1979 by the Energy Information Administration. Approximately 6,600 commercial buildings were surveyed, representing the characteristics and energy consumption of 4.8 million commercial buildings and 67.9 billion square feet of commercial floorspace nationwide. Overall, the amount of commercial floorspace in the United States increased an average of 2.4 percent annually between 1989 and 1992, while the number of commercial buildings increased an average of 2.0 percent annually.

    Heinicke, W.; Krug, H.; Thomas, W.; Weber, W.; Gmal, B.

    1985-12-01

    The GRS Criticality Handbook is intended as a source of information on criticality problems for the persons concerned in industry, authorities, or research laboratories. It is to serve as a guide allowing quick and appropriate evaluation of criticality problems during design or erection of nuclear installations. This present issue replaces the one published in 1979, presenting revised and new data in a modified construction, but within the framework of the proven basic structure of the Handbook. Some fundamental knowledge is required of criticality problems and the relevant terms and definitions of nuclear safety, in order to fully deploy the information given. Part 1 of the Handbook therefore first introduces terminology and definitions, followed by experimental methods and calculation models for criticality calculations. The next chapters deal with the function and efficiency of neutron reflectors and neutron absorbers, measuring methods for criticality monitoring, organisational safety measures, and criticality accidents and their subsequent analysis.

  7. Commercial newsgathering from space

    Science.gov (United States)

    1987-05-01

    This memorandum does not examine the feasibility of a specific satellite system or business plan, but rather, assesses whether current government policy is appropriate to accommodate both current activities and future developments of the use of satellite images to cover newsworthy events. The mediasat term refers to a concept of a satellite system and business organization that would routinely collect news and information for media use from space. Because the mediasat concept is, for the most part, undefined, the Office of Technology Assessment (OTA) was forced to make a series of assumptions regarding fundamental issues as cost, markets, technical capability, and utility of a mediasat. Although these assumptions are critical to OTA's conclusions, they are only best guesses, based on the advice of experts in the media and in the field of remote sensing. With regard to specific issues, such as the economic viability of a mediasat or its effect on national security and foreign policy, altering these underlying assumptions could dramatically alter the conclusions reached.

    2010-05-01

    Landloch Pty Ltd is a commercial consulting firm, providing advice on a range of land management issues to the mining and construction industries in Australia. As part of the company's day-to-day operations, rainfall simulation is used to assess material erodibility and to investigate a range of site attributes. (Landloch does carry out research projects, though such are not its core business.) When treated as an everyday working tool, several aspects of rainfall simulation practice are distinctively modified. Firstly, the equipment used is regularly maintained, and regularly upgraded with a primary focus on ease, safety, and efficiency of use and on reliability of function. As well, trained and experienced technical support is considered essential. Landloch's chief technician has over 10 years experience in running rainfall simulators at locations across Australia and in Africa and the Pacific. Secondly, the specific experimental conditions established for each set of rainfall simulator runs are carefully considered to ensure that they accurately represent the field conditions to which the data will be subsequently applied. Considerations here include: • wetting and drying cycles to ensure material consolidation and/or cementation if appropriate; • careful attention to water quality if dealing with clay soils or with amendments such as gypsum; • strong focus on ensuring that the erosion processes considered are those of greatest importance to the field situation of concern; and • detailed description of both material and plot properties, to increase the potential for data to be applicable to a wider range of projects and investigations. Other important company procedures include: • For each project, the scientist or engineer responsible for analysing and reporting rainfall simulator data is present during the running of all field plots, as it is essential that they be aware of any specific conditions that may have developed when the plots were subjected

  15. ETHICS AND COMMERCIAL COMMUNICATION

    Directory of Open Access Journals (Sweden)

    Flaviu MEGHIŞAN

    2014-10-01

    Full Text Available The modern economic science was built around the concept of efficiency. In economy the notion of equality is strongly correlated with the notion of balance, such as the market balance when the demand equals the offer. In a broader view, the economy cannot contribute to a reflection on equity unless it re-became a moral and political science or even a philosophical economy. At present, when there is an effervescence of international transactions, we all adulate the need for morality. Everyday, all around the world, regular people are affected by the costs of ethical issues. The profit and social responsibility do not exclude reciprocally. The social value of a company is given by the well-being and the work-places generated, by the products and services offered to the consumers at a fair price in correlation with the quality. The sentimental value represents the value that a person is giving to a good, based on feelings and emotions and not on monetary values. In many cases the passions and the interests are more powerful than the moral value that animates us. A lot of commercials, if they are to say the truth, would recognize that, for them, not the clients are important but the profits.

  16. Advanced commercial tokamak study

    Thomson, S.L.; Dabiri, A.E.; Keeton, D.C.; Brown, T.G.; Bussell, G.T.

    1985-12-01

    Advanced commercial tokamak studies were performed by the Fusion Engineering Design Center (FEDC) as a participant in the Tokamak Power Systems Studies (TPSS) project coordinated by the Office of Fusion Energy. The FEDC studies addressed the issues of tokamak reactor cost, size, and complexity. A scoping study model was developed to determine the effect of beta on tokamak economics, and it was found that a competitive cost of electricity could be achieved at a beta of 10 to 15%. The implications of operating at a beta of up to 25% were also addressed. It was found that the economics of fusion, like those of fission, improve as unit size increases. However, small units were found to be competitive as elements of a multiplex plant, provided that unit cost and maintenance time reductions are realized for the small units. The modular tokamak configuration combined several new approaches to develop a less complex and lower cost reactor. The modular design combines the toroidal field coil with the reactor structure, locates the primary vacuum boundary at the reactor cell wall, and uses a vertical assembly and maintenance approach. 12 refs., 19 figs

  17. Balancing energy conservation and occupant needs in ventilation rate standards for Big Box stores and other commercial buildings in California. Issues related to the ASHRAE 62.1 Indoor Air Quality Procedure

    Energy Technology Data Exchange (ETDEWEB)

    Mendell, Mark J. [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Apte, Mike G. [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)

    2010-10-31

    This report considers the question of whether the California Energy Commission should incorporate the ASHRAE 62.1 ventilation standard into the Title 24 ventilation rate (VR) standards, thus allowing buildings to follow the Indoor Air Quality Procedure. This, in contrast to the current prescriptive standard, allows the option of using ventilation rate as one of several strategies, which might include source reduction and air cleaning, to meet specified targets of indoor air concentrations and occupant acceptability. The research findings reviewed in this report suggest that a revised approach to a ventilation standard for commercial buildings is necessary, because the current prescriptive ASHRAE 62.1 Ventilation Rate Procedure (VRP) apparently does not provide occupants with either sufficiently acceptable or sufficiently healthprotective air quality. One possible solution would be a dramatic increase in the minimum ventilation rates (VRs) prescribed by a VRP. This solution, however, is not feasible for at least three reasons: the current need to reduce energy use rather than increase it further, the problem of polluted outdoor air in many cities, and the apparent limited ability of increasing VRs to reduce all indoor airborne contaminants of concern (per Hodgson (2003)). Any feasible solution is thus likely to include methods of pollutant reduction other than increased outdoor air ventilation; e.g., source reduction or air cleaning. The alternative 62.1 Indoor Air Quality Procedure (IAQP) offers multiple possible benefits in this direction over the VRP, but seems too limited by insufficient specifications and inadequate available data to provide adequate protection for occupants. Ventilation system designers rarely choose to use it, finding it too arbitrary and requiring use of much non-engineering judgment and information that is not readily available. This report suggests strategies to revise the current ASHRAE IAQP to reduce its current limitations. These

    2013-05-01

    Complementary and alternative medicine (CAM) has gained increasing popularity over the last several decades internationally, leading to an increasing interest from decision makers and researchers as to how to assess the effectiveness of CAM. The attempts, however, have been unsatisfactory. The most important reason is a lack of attention to the theoretical characteristics of CAM, which are completely different from those of allopathic medicine or biomedicine. This study attempted to survey expert Traditional Chinese Medicine (TCM) practitioners in China to elucidate critical issues when assessing the effectiveness of TCM. A questionnaire (with 20 close-ended and 2 open-ended questions) about the influencing factors of measuring the cost and effectiveness of TCM was distributed to TCM practitioners who had been working in the field of research for at least 5 years and had published at least one related scientific article in the last 5 years. Internal consistency test was performed for all questions to verify the reliability of the questionnaire. Principal-component analysis was performed for remaining items after Kaiser-Meyer-Olkin (KMO) index and Bartlett's test of sphericity. A linear combination model was then built to evaluate the contribution of various factors involved for the selection of TCM into the health care reimbursement or insurance system. Of 429 questionnaires issued, 137 were returned from respondents from 31 medical and research institutions, giving a recovery rate of 31.93%. Internal consistency coefficient obtained was 0.745, indicating good reliability of this measurement scale, and the data passed the KMO test and Bartlett's test of sphericity (KMO index = 0.691). In addition, eight common factors were extracted after the rotation of principal-component analysis with a cumulative variance of 70.92%. Our findings suggested that factors to be considered during the selection of TCM in health care reimbursement or insurance system include patient

    Full Text Available The world popularity and effectiveness of the American system of higher education encourages other countries to use its borrowed elements in the national education systems. The issues of integration within a single reform, within a single national education system cannot be solved because it is accompanied by the need to overcome a number of related conceptual problems. One of the major conceptual problems of national education is its commercialization. The example of education is where commercialization is the mechanism and the result of the reform American education. In American society there are two approaches to the issue of obtaining higher education. First, the so­called “Jeffersonville”, provides for equality of access to higher education, but subject to the production of high demands for qualities (abilities. Second, the so­called “Jacksonville”, also recognized the equality of access to higher education, but it is believed that the University should be free for everyone who has completed secondary education, regardless of ability. Despite the undeniable efficiency, impressive achievements in science, structural diversity and structure on democratic principles of the higher education system, the last few decades in American society does not cease its criticism, because universities and colleges are only indirectly fulfill the function of serving society.

    2000-01-01

    There is a significant and growing commercial market for new, more capable communications and remote sensing satellites. Competition in this market strongly motivates satellite manufacturers and spacecraft component developers to test and demonstrate new space hardware in a realistic environment. External attach points on the International Space Station allow it to function uniquely as a space technology testbed to satisfy this market need. However, space industry officials have identified three critical barriers to their commercial use of the ISS: unpredictable access, cost risk, and schedule uncertainty. Appropriate NASA policy initiatives and business/technical assistance for industry from the Commercial Space Center for Engineering can overcome these barriers. .

    This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development (WPD) department with the objective of providing a comprehensive, conservative estimate of the consequences of the criticality which could possibly occur as the result of commercial spent nuclear fuel emplaced in the underground repository at Yucca Mountain. The consequences of criticality are measured principally in terms of the resulting changes in radionuclide inventory as a function of the power level and duration of the criticality. The purpose of this analysis is to extend the prior estimates of increased radionuclide inventory (Refs. 5.52 and 5.54), for both internal and external criticality. This analysis, and similar estimates and refinements to be completed before the end of fiscal year 1997, will be provided as input to Total System Performance Assessment-Viability Assessment (TSPA-VA) to demonstrate compliance with the repository performance objectives

  12. Commercial Research and Development: Power to Explore, Opportunities from Discovery

    Science.gov (United States)

    Casas, Joseph C.; Nall, Mark; Powers, C. Blake; Henderson, Robin N. (Technical Monitor)

    2002-01-01

    The technical and economic goals of commercial use of space are laudable, and are addressed as a high priority by almost every national space program and most major aerospace companies the world over. Yet, the focus of most organizational agendas and discussions tends to focus on one or two very narrow enabling aspects of this potentially large technological and economic opportunity. While government sponsored commercial launch activities and private space platforms are an integral part of efforts to leverage the commercial use of space, these activities are possibly one of the smallest parts of creating, a viable and sustainable market for the commercial use of space. Most of the current programs usually do not appropriately address some of the critical issues of the current, already interested, potential space user communities. Current programs place the focus of the majority of the user requirements on the vehicle payload weight and mass performance considerations as the primary payload economical factor in providing a commercial market with a stimulating price for gaining access to the space environment. The larger user challenges of transformation from Earth-based research and development approaches to space environment approaches are not addressed early enough in programs to impact the new business considerations of potential users. Currently, space-based research and development user activities require a large user investment in time, in development of new areas of support expertise, in development of new systems, in risk of schedule to completion, and in long term capital positioning. The larger opportunities for stimulating a strong market driven interest in commercial use of space that could result from the development of vehicle payload "leap ahead technologies" for users are being missed, and there is a real risk of limiting the potentially broader market base to support a more technologically advanced and economically lucrative outcome. A major driving

    Issues about commercialization of space have been a growing concern in the past decade for the space community. This paper focuses on the work from a team of 51 students attending the Summer Session Program of the International Space University in Bremen, Germany. CASH 2021 (Commercial Access and Space Habitation) documents a plan that identifies commercial opportunities for space utilization that will extend human presence in space, and will chart the way forward for the next 20 years. The group selected four commercial sectors that show the most promise for the future: tourism, entertainment, space system service, assembly and debris removal, and research and development/production. The content of this document presents the results of their research. Historical activities in each of the commercial sectors are reviewed along with the current market situation. To provide a coherent background for future commercialization possibilities a scenario has been developed. This scenario includes a postulated upon ideal future and includes social, political and economic factors that may affect the space industry over the timeline of the study. The study also presents a roadmap, within the limited optimistic scenario developed, for the successful commercialization of space leading to future human presence in space. A broad range of commercially viable opportunities, not only within the current limits of the International Space Station, but also among the many new developments that are expected by 2021 are discussed.

    The treatment of human interactions is considered one of the major limitations in the context of Probabilistic Safety Assessment (PSA).While the results of many PSAs show a very significant contribution of human errors, large uncertainties are normally associated with the quantitative estimates of these contributors. This problem becomes even more significant when analysing human interactions under special conditions, for example in accident scenarios for external events or for the shutdown and low power conditions. Any improvement in the current state of knowledge with respect to the data for human interactions would have a positive impact on the confidence in PSA results, including correct ranking of the dominant accident scenarios. At the same time many PSAs have been successful at identifying critical operator actions; in most cases the benefits of these qualitative insights are not jeopardised by lack of numerical precision in the estimates. The present HRA approaches as generally applied in PSAs are also limited in scope; for instance, they either ignore errors of commissions or treat these superficially. New, dynamic methods, primarily aiming at the resolution of the issues of cognitive errors including errors of commission are emerging but their full-scope applications within the PSA framework belong to the future. In the context of data, some progress has been observed partially due to use of simulators to support the human reliability analysis (HRA). These applications have been rather concentrated (but not limited) to France and USA. Recently, a very promising program has been established in Hungary. The experiences from such applications are not widely known and dissemination of the relevant insights to the PSA community has some definite merits. With respect to the identification of critical operator actions there is in some cases clear evidence and in others a good potential that the existing PSA studies may provide useful, partially generic

  16. Recycling Sounds in Commercials

    Commercials offer the opportunity for intergenerational memory and impinge on cultural memory. TV commercials for foodstuffs often make reference to past times as a way of authenticating products. This is frequently achieved using visual cues, but in this paper I would like to demonstrate how...... such references to the past and ‘the good old days’ can be achieved through sounds. In particular, I will look at commercials for Danish non-dairy spreads, especially for OMA margarine. These commercials are notable in that they contain a melody and a slogan – ‘Say the name: OMA margarine’ – that have basically...... remained the same for 70 years. Together these identifiers make OMA an interesting Danish case to study. With reference to Ann Rigney’s memorial practices or mechanisms, the study aims to demonstrate how the auditory aspects of Danish margarine commercials for frying tend to be limited in variety...

  17. Prospects for commercial fusion power

    International Nuclear Information System (INIS)

    Dean, S.O.

    1993-01-01

    There are a number of issues associated with whether or not, and when, fusion will become commercial. One of the largest factors is cost of development. Development is being delayed by the need to work with other countries to share these costs. Other aspects have to do with the capital costs of the reactors themselves. The ITER reactor may cost 6-7 billion dollars, which is a sizeable investment for a test reactor. The safety and environmental aspects of fusion are other factors which have delayed commercialization. Public acceptance of this form of nuclear power and the licensing and regulatory procedures must be resolved before electric utilities are willing to invest heavily in fusion. The Department of Energy has developed a plan as part of the Energy Policy Act of 1992, wherein a first demonstration power plant will be operating around the year 2025. Much of the ongoing effort is directed toward reducing the size and cost of Tokamak reactors. While Tokamaks are not the only game in town, it is the primary thrust of the world effort and it is the technology which is expected to lead into the first generation of commercial fusion reactors

    The answers to the questions: How many reactors will face the end of their operating lifetime over the next few decades? To what extent are the issues of decommissioning urgent? The answers will lead us to those issues that should be tackled now in order to complete smoothly the decommissioning of commercial nuclear power plants. The prospective needs for decommissioning of nuclear power plants are illustrated from the viewpoint of reactor age, and some of the issues to be tackled, in particular by governments, in this century are discussed, to prepare for the future decommissioning activities.

  5. Furthering critical institutionalism

    Directory of Open Access Journals (Sweden)

    Frances Dalton Cleaver

    2015-03-01

    Full Text Available This special issue furthers the study of natural resource management from a critical institutional perspective. Critical institutionalism (CI is a contemporary body of thought that explores how institutions dynamically mediate relationships between people, natural resources and society. It focuses on the complexity of institutions entwined in everyday social life, their historical formation, the interplay between formal and informal, traditional and modern arrangements, and the power relations that animate them. In such perspectives a social justice lens is often used to scrutinise the outcomes of institutional processes. We argue here that critical institutional approaches have potentially much to offer commons scholarship, particularly through the explanatory power of the concept of bricolage for better understanding institutional change.  Critical institutional approaches, gathering momentum over the past 15 years or so, have excited considerable interest but the insights generated from different disciplinary perspectives remain insufficiently synthesised. Analyses emphasising complexity can be relatively illegible to policy-makers, a fact which lessens their reach. This special issue therefore aims to synthesise critical institutional ideas and so to lay the foundation for moving beyond the emergent stage to make meaningful academic and policy impact. In bringing together papers here we define and synthesise key themes of critical institutionalism, outline the concept of institutional bricolage and identity some key challenges facing this school of thought.

    Full Text Available Games can serve a critical function in many different ways, from serious games about real world subjects to self-reflexive commentaries on the nature of games themselves. In this essay we discuss critical possibilities stemming from the area of critical design, and more specifically Carl DiSalvo’s adversarial design and its concept of reconfiguring the remainder. To illustrate such an approach, we present the design and outcomes of two games, Jostle Bastard and Jostle Parent. We show how the games specifically engage with two previous games, Hotline Miami and Octodad: Dadliest Catch, reconfiguring elements of those games to create interactive critical experiences and extensions of the source material. Through the presentation of specific design concerns and decisions, we provide a grounded illustration of a particular critical function of videogames and hope to highlight this form as another valuable approach in the larger area of videogame criticism.

  15. Criticality Model

    International Nuclear Information System (INIS)

    Alsaed, A.

    2004-01-01

    The ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2003) presents the methodology for evaluating potential criticality situations in the monitored geologic repository. As stated in the referenced Topical Report, the detailed methodology for performing the disposal criticality analyses will be documented in model reports. Many of the models developed in support of the Topical Report differ from the definition of models as given in the Office of Civilian Radioactive Waste Management procedure AP-SIII.10Q, ''Models'', in that they are procedural, rather than mathematical. These model reports document the detailed methodology necessary to implement the approach presented in the Disposal Criticality Analysis Methodology Topical Report and provide calculations utilizing the methodology. Thus, the governing procedure for this type of report is AP-3.12Q, ''Design Calculations and Analyses''. The ''Criticality Model'' is of this latter type, providing a process evaluating the criticality potential of in-package and external configurations. The purpose of this analysis is to layout the process for calculating the criticality potential for various in-package and external configurations and to calculate lower-bound tolerance limit (LBTL) values and determine range of applicability (ROA) parameters. The LBTL calculations and the ROA determinations are performed using selected benchmark experiments that are applicable to various waste forms and various in-package and external configurations. The waste forms considered in this calculation are pressurized water reactor (PWR), boiling water reactor (BWR), Fast Flux Test Facility (FFTF), Training Research Isotope General Atomic (TRIGA), Enrico Fermi, Shippingport pressurized water reactor, Shippingport light water breeder reactor (LWBR), N-Reactor, Melt and Dilute, and Fort Saint Vrain Reactor spent nuclear fuel (SNF). The scope of this analysis is to document the criticality computational method. The criticality

  20. DO WE STILL NEED A CONVENTION IN THE FIELD OF HARMONISATION OF THE INTERNATIONAL COMMERCIAL LAW?

    Directory of Open Access Journals (Sweden)

    A. Korzhevskaya

    2014-01-01

    Full Text Available The paper critically discusses the opinion of certain scholars that the use of multilateral treaties (conventions in the field of harmonisation of international commercial law has been in a state of steady decline. They believe that traditional treaty law has been gradually replaced in recent years by softer methods of making international law, such as the use of restatements and model laws. Some scholars even claim that treaty law is dead or dying. The work assesses whether this view has reasonable grounds, providing an overview of the most prominent hard law and soft law harmonising instruments and outlining issues relating to the success of conventions, their advantages, drawbacks and tensions arising in this area. The paper suggests that conventions remain necessary where the third party or public interest are at stake, however, further improvements are needed to make conventions more successful instruments in international commercial law.

    2016-12-01

    Full Text Available This paper consists of two parts. The first deals with the issue of whether it is possible to coherently employ the term ‘critical Confucian’ in general, i.e. whether it is a paradox or oxymoron. It will be argued that Confucianism should not be identified with any particular ideology and, therefore, can be critical. This critical potential, in turn, can be developed by bringing it into dialogue with Critical Theory. As such, the second part indicates, in an introductory way, some possible overlaps between Confucianism and Critical Theory by comparing Heiner Roetz’s and Axel Honneth’s respective interpretations of these traditions.

    This session on transmission issues focused on the role that transmission plays in electricity markets and the importance of getting the market structure right in terms of generation divestiture with buy back contracts, demand side responsive programs, transmission upgrades and long term contracts. The difficulties of distinguishing between market power and scarcity were examined along with some of the complications that ensue if transmission experiences congestion, as exemplified by the August 2003 blackout in eastern North America. The presentations described the best ways to handle transmission issues, and debated whether transmission should be deregulated or follow market forces. Issues of interconnections and reliability of connections were also debated along with the attempt to integrate renewables into the grid. Some presentations identified what new transmission must be built and what must be done to ensure that transmission gets built. The challenges and business opportunities for transmission in Alberta were discussed with reference to plans to invest in new infrastructure, where it is going outside of the province and how it works with other jurisdictions. Manitoba's Conawapa Hydro Project and its 2000 MW tie line to Ontario was also discussed. Some examples of non-optimal use of interconnections in Europe were also discussed in an effort to learn from these mistakes and avoid them in Canada. tabs., figs

    The New Brunswick Market Design Committee has examined several issues regarding the restructuring of the province's electricity sector. This report presents issues that require guidance for implementation, with particular focus on options available for their resolutions. The issues include: (1) rate principles for stranded offer service (SOS) supply, (2) the ability of contestable customers to return to SOS after having left it, (3) whether loads embedded in distribution systems are eligible to participate in the bilateral contract market, (4) whether generators or suppliers can offer capacity and energy to SOS suppliers in competition with the SOS supplier, and (5) details for the balancing market, including pricing, bidding protocols, settlements and how intermittent power sources can participate in the market. A section on pricing for SOS explains pricing principles, the use of export profits, pricing for SOS capacity, and time of use pricing. The Committee has made recommendations for the electricity system in the province to have an energy imbalance service that can move towards a market in order to develop an efficient and effective service. This report also explains pricing in the balancing market, penalties, and settlements. 7 refs

    The erection process is simple; often used civil engineering structures. The structure can be manufactured apart from the site and can be assembled on site within short time.The relatively light steel construction (compared to reinforced concrete)could be erected on existing building surrounding the containment, thus reducing the necessary height compared to free standing massive concrete structures. In many cases it has to be constructed on only one or two sides on the containment, as the containment building is usually not accessible. The costs of such a structure compared to free standing reinforced concrete are lower.

    A criticality accident in a MOX fuel fabrication facility may occur depending on several parameters, such as mass inventory and plutonium enrichment. MOX handling units in the facility are designed and operated based on the double contingency principle to prevent criticality accidents. Control failures of at least two parameters are needed for the occurrence of criticality accident. To evaluate the probability of such control failures, the criticality conditions of each parameter for a specific handling unit are necessary for accident scenario analysis to be clarified quantitatively with a criticality analysis computer code. In addition to this issue, a computer-based control system for mass inventory is planned to be installed into MOX handling equipment in a commercial MOX fuel fabrication plant. The reliability analysis is another important issue in evaluating the likelihood of control failure caused by software malfunction. A likelihood estimation method for criticality accident has been developed with these issues been taken into consideration. In this paper, an example of analysis with the proposed method and the applicability of the method are also shown through a trial application to a model MOX fabrication facility. (author)

    Our recent studies have concentrated on developing optimal high beta (bean-shaped plasma) commercial tokamak configurations using TRW's Tokamak Reactor Systems Code (TRSC) with special emphasis on lower net electric power reactors that are more easily deployable. A wide range of issues were investigated in the search for the most economic configuration: fusion power, reactor size, wall load, magnet type, inboard blanket and shield thickness, plasma aspect ratio, and operational β value. The costs and configurations of both steady-state and pulsed reactors were also investigated. Optimal small and large reactor concepts were developed and compared by studying the cost of electricity from single units and from multiplexed units. Multiplexed units appear to have advantages because they share some plant equipment and have lower initial capital investment as compared to larger single units

    Full Text Available There are many ways to categorise conspiracy theories. In the present study, we examined individual and demographic predictors of beliefs in commercial conspiracy theories among a British sample of over 300 women and men. Results showed people were cynical and sceptical with regard to advertising tricks, as well as the tactics of organisations like banks and alcohol, drug and tobacco companies. Beliefs sorted into four identifiable clusters, labelled sneakiness, manipulative, change-the-rules and suppression/prevention. The high alpha for the overall scale suggested general beliefs in commercial conspiracy. Regressions suggested that those people who were less religious, more left-wing, more pessimistic, less (self-defined as wealthy, less Neurotic and less Open-to-Experience believed there was more commercial conspiracy. Overall the individual difference variables explained relatively little of the variance in these beliefs.The implications of these findings for the literature on conspiracy theories are discussed.

  15. Commercial and Institutional Waste

    Commercial and institutional waste is primarily from retail (stores), hotels, restaurants, health care (except health risk waste), banks, insurance companies, education, retirement homes, public services and transport. Within some of these sectors, e.g. retail and restaurants, large variations...... are found in terms of which products and services are offered. Available data on unit generation rates and material composition as well as determining factors are discussed in this chapter. The characterizing of commercial and institutional waste is faced with the problem that often only a part of the waste...... is handled in the municipal waste system, where information is easily accessible. An important part of commercial and institutional waste is packaging waste, and enterprises with large quantities of clean paper, cardboard and plastic waste may have their own facilities for baling and storing their waste...

    ANSTO, in partnership with Australian and overseas organisations, continues to make significant contributions to selected fields of research and development. Major revenue for ANSTO is generated through sales of radiopharmaceuticals and radioisotopes for medical, industrial, environmental and research purposes and through neutron irradiation services. Further, ANSTO is actively trying to generate maximum value from its knowledge and know-how through protection and exploitation of its intellectual property. Strategic alliances have been developed to further the commercial utilisation of ANSTO know-how in, for example, delivery systems for tumour treatments, commercial waste remediation and applications of plasma implantation. The 2000-2001 financial year saw the establishment of an ANSTO business unit called Sulfide Solutions targeted at better management of environmental issues arising from mining operations. Overall, ANSTO's capacity to generate value from the application of its knowledge and know-how is being increasingly acknowledged, the organisation attaining credibility as an international leader in the application of nuclear science and technology in targeted areas

    Full Text Available In the above article author describes evolution of legal regulation of international commercial arbitration in Venezuela. Author cites statistics of arbitration centers in Venezuela activities. In past two decades many Latin American countries have reformed their arbitration law. In an effort to modernize its arbitral institutions several Latin American countries adopted Model Law on International Commercial Arbitration of the UN Commission on International Trade Law (UNCITRAL. In addition, many Latin American countries have adopted the monistic system. Author pays detailed attention to this issue, discusses concept of a monistic system - a system in which a unique set of rules governs both domestic and international arbitration. Author argues that legal system of Venezuela fits this definition. Venezuelan law on arbitration in 1998 makes no distinction between domestic and international arbitration. Arbitration was included in judicial system under the Constitution of Venezuela of the 1999. Art. 258 of the Venezuelan Constitution states that arbitration, conciliation and mediation are alternative ways of resolving disputes.

  18. Commercial incineration demonstration

    1982-01-01

    Low-level radioactive wastes (LLW) generated by nuclear utilities presently are shipped to commercial burial grounds for disposal. Increasing transportation and disposal costs have caused industry to consider incineration as a cost-effective means of volume reduction of combustible LLW. Repeated inquiries from the nuclear industry regarding the applicability of the Los Alamos controlled air incineration (CAI) design led the DOE to initiate a commercial demonstration program in FY-1980. Development studies and results in support of this program involving ion exchange resin incineration and fission/activation product distributions within the Los Alamos CAI are described

  19. Womb Outsourcing: Commercial Surrogacy in India.

    Science.gov (United States)

    Frankford, David M; Bennington, Linda K; Ryan, Jane Greene

    2015-01-01

    Infertility affects more than 7 million American couples. As traditional treatments fail and the costs of hiring a surrogate increase in the United States, transnational commercial surrogacy becomes a feasible alternative for many couples. Infertile couples may opt for this choice after reading enticing Internet advertisements of global medical tourism offering "special deals" on commercial surrogacy. This is particularly true in India where couples from the United States can purchase transnational surrogacy for less than one-half or even one-third of the costs in the United States, including the cost of travel. The majority of surrogate mothers in India come from impoverished, poorly educated rural areas of India. Commercial surrogacy offers the lure of earning the equivalent of 5 years of family income. This multidisciplinary review of the literature suggests that the issue of commercial surrogacy is complex and influenced by a number of factors including expensive infertility costs, ease of global travel, and the financial vulnerability of Indian commercial surrogate mothers and their families. Questions are being raised about decision making by the surrogate mother particularly as influenced by gender inequities, power differentials, and inadequate legal protection for the surrogate mother. More research is needed to understand commercial surrogacy, especially research inclusive of the viewpoints of the Indian mothers and their families involved in these transactions.

  20. Context-Aware Online Commercial Intention Detection

    Science.gov (United States)

    Hu, Derek Hao; Shen, Dou; Sun, Jian-Tao; Yang, Qiang; Chen, Zheng

    With more and more commercial activities moving onto the Internet, people tend to purchase what they need through Internet or conduct some online research before the actual transactions happen. For many Web users, their online commercial activities start from submitting a search query to search engines. Just like the common Web search queries, the queries with commercial intention are usually very short. Recognizing the queries with commercial intention against the common queries will help search engines provide proper search results and advertisements, help Web users obtain the right information they desire and help the advertisers benefit from the potential transactions. However, the intentions behind a query vary a lot for users with different background and interest. The intentions can even be different for the same user, when the query is issued in different contexts. In this paper, we present a new algorithm framework based on skip-chain conditional random field (SCCRF) for automatically classifying Web queries according to context-based online commercial intention. We analyze our algorithm performance both theoretically and empirically. Extensive experiments on several real search engine log datasets show that our algorithm can improve more than 10% on F1 score than previous algorithms on commercial intention detection.

    Full Text Available This essay considers how written language frames visual objects. Drawing on Michel Foucault’s response to Raymond Roussel’s obsessive description, the essay proposes a model of criticism where description might press up against its objects. This critical closeness is then mapped across the conceptual art practice and art criticism of Ian Burn. Burn attends to the differences between seeing and reading, and considers the conditions which frame how we look at images, including how we look at, and through words. The essay goes on to consider Meaghan Morris’s writing on Lynn Silverman’s photographs. Both Morris and Burn offer an alternative to a parasitic model of criticism and enact a patient way of looking across and through visual landscapes.

  4. In the business of dying: questioning the commercialization of hospice.

    Science.gov (United States)

    Perry, Joshua E; Stone, Robert C

    2011-01-01

    This article critically questions the commercialization of hospice care and the ethical concerns associated with the industry's movement toward "market-driven medicine" at the end of life. For example, the article examines issues raised by an influx of for-profit hospice providers whose business model appears at its core to have an ethical conflict of interest between shareholders doing well and terminal patients dying well. Yet, empirical data analyzing the experience of patients across the hospice industry are limited, and general claims that end-of-life patient care is inferior among for-profit providers or even that their business practices are somehow unseemly when compared to nonprofit providers cannot be substantiated. In fact, non-profit providers are not immune to potentially conflicting concerns regarding financial viability (i.e., "no margin, no mission"). Given the limitations of existing empirical data and contrasting ideological commitments of for-profit versus non-profit providers, the questions raised by this article highlight important areas for reflection and further study. Policymakers and regulators are cautioned to keep ethical concerns in the fore as an increasingly commercialized hospice industry continues to emerge as a dominant component of the U.S. health care system. Both practitioners and researchers are encouraged to expand their efforts to better understand how business practices and commercial interests may compromise the death process of the patient and patient's family--a process premised upon a philosophy and ethical tradition that earlier generations of hospice providers and proponents established as a trusted, end-of-life alternative. © 2011 American Society of Law, Medicine & Ethics, Inc.

  5. Criticality safety

    International Nuclear Information System (INIS)

    Walker, G.

    1983-01-01

    When a sufficient quantity of fissile material is brought together a self-sustaining neutron chain reaction will be started in it and will continue until some change occurs in the fissile material to stop the chain reaction. The quantity of fissile material required is the 'Critical Mass'. This is not a fixed quantity even for a given type of fissile material but varies between quite wide limits depending on a number of factors. In a nuclear reactor the critical mass of fissile material is assembled under well-defined condition to produce a controllable chain reaction. The same materials have to be handled outside the reactor in all stages of fuel element manufacture, storage, transport and irradiated fuel reprocessing. At any stage it is possible (at least in principle) to assemble a critical mass and thus initiate an accidental and uncontrollable chain reaction. Avoiding this is what criticality safety is all about. A system is just critical when the rate of production of neutrons balances the rate of loss either by escape or by absorption. The factors affecting criticality are, therefore, those which effect neutron production and loss. The principal ones are:- type of nuclide and enrichment (or isotopic composition), moderation, reflection, concentration (density), shape and interaction. Each factor is considered in detail.

  7. National Space Agencies vs. Commercial Space: Towards Improved Space Safety

    Science.gov (United States)

    Pelton, J.

    2013-09-01

    Traditional space policies as developed at the national level includes many elements but they are most typically driven by economic and political objectives. Legislatively administered programs apportion limited public funds to achieve "gains" that can involve employment, stimulus to the economy, national defense or other advancements. Yet political advantage is seldom far from the picture.Within the context of traditional space policies, safety issues cannot truly be described as "afterthoughts", but they are usually, at best, a secondary or even tertiary consideration. "Space safety" is often simply assumed to be "in there" somewhere. The current key question is can "safety and risk minimization", within new commercial space programs actually be elevated in importance and effectively be "designed in" at the outset. This has long been the case with commercial aviation and there is at least reasonable hope that this could also be the case for the commercial space industry in coming years. The cooperative role that the insurance industry has now played for centuries in the shipping industry and for decades in aviation can perhaps now play a constructive role in risk minimization in the commercial space domain as well. This paper begins by examining two historical case studies in the context of traditional national space policy development to see how major space policy decisions involving "manned space programs" have given undue primacy to "political considerations" over "safety" and other factors. The specific case histories examined here include first the decision to undertake the Space Shuttle Program (i.e. 1970-1972) and the second is the International Space Station. In both cases the key and overarching decisions were driven by political, schedule and cost considerations, and safety seems absence as a prime consideration. In publicly funded space programs—whether in the United States, Europe, Russia, Japan, China, India or elsewhere—it seems realistic to

  8. Liability Issues

    O’Donoghue, K.

    2016-01-01

    Nuclear liability conventions try to provide a set of rules to govern third party liability. Not all States are parties to one of the existing liability conventions. There are a number of reasons why individual States may choose not to join one of the existing conventions. These include limits of compensation, jurisdiction issues, complexity, cost and definition of damage among others. This paper looks at the existing conventions and identifies some of the main issues in the existing conventions which prevent some States from signing them. The paper attempts to tease out some of the perceived gaps in the existing conventions and give a brief description of the reasons why non-Contracting Parties have difficulty with the provisions of the conventions. The paper recognizes that there has been work done in this area previously by the International Expert Group on Nuclear Liability (INLEX) and others to try to develop the existing frameworks to enhance global adherence by nuclear and non-nuclear States to an effective nuclear liability regime.

    1994-06-01

    Savannah River Site (SRS), particularly the Savannah River Technology Center (SRTC) with the experience from the first successful Integrated Technology Demonstration, can provide an excellent foundation for meeting DOE-EM`s objectives with the new DOE-EM five focus area approach. With this in mind, SRTC established an activity to pursue full commercialization of environmental technologies. This report is an assessment of the status of commercialization at SRS and provides recommendations for enhancement as well as some tools critical to implementation. A review was made of the current situation at SRS with regards to taking technology development to commercial fruition. This was done from the perspective of comparing it to known commercialization models and processes. It was found that SRTC already works through many of the steps in these processes. With integration and action-oriented efforts of the inclusion of business and market factors, SRTC could become an aggressive, successful developer of commercialized technologies. Commercial success criteria tools were developed with regards to integrating them with SRTC selection criteria to ensure that all critical factors are covered in technology commercialization project evaluations. Private investors are very clear that their interest lies in funding commercial enterprises, not merely technologies. Mobilizing private capital is critical to real job growth and long-term economic development. Also, potential industry partners were identified that are willing to be involved with SRS` technology applications and regional development efforts. As another important component to success, regional support organizations were reviewed and evaluated.

    1992-01-01

    To provide guidance for the Department of Energy's (DOE) Civilian Radioactive Waste Management Program, the Nuclear Regulatory Commission (NRC) has issued a draft regulatory guide on the Format and Content for the License Application for the High-Level Waste Repository (FCRG). To facilitate the development of the FCRG, NRC suggested that DOE use the draft guide as the basis for preparing an annotated outline for a license application. DOE is doing so using an iterative process called the Annotated Outline Initiative. DOE;s use of the Initiative will assist in achieving the desired incorporation of actual experience in the FCRG, contribute to the development of shared interpretation and understanding of NRC regulations, and provide other important programmatic benefits described in this paper

    Hicks, D.W.

    1986-01-01

    This paper is based on the assumption that the nuclear debate, both globally and within Britain, is one of critical importance in the late twentieth century and that it should therefore, at some juncture, be explored as part of the school curriculum. An essential part of 'good education' in a democratic society is to teach young people how to think about such an issue, but not what to think about it. This paper attempts to set out some of the key issues and dilemmas in relation to what we may call 'nuclear education'. It perhaps asks more questions than it gives answers, but they are all essential questions which teachers must ask themselves if they are to teach sensitively about these matters. Some of these questions are given as examples. (author)
