    2006-09-01

    International declarations have affirmed that health is a universal right. In order for people to exercise their right to health, their social and cultural contexts need to be acknowledged. However, due to a number of barriers encountered at different levels of society and geographically this right is not yet fully exercised by a considerable number of women in Latin America. During the last decade progress has been made in the development of public health policies and programs that integrate and recognize the differences in culture that should be considered when addressing indigenous women's health issues. However, a biomedical health model, which discounts cultural influences, prevails globally over a more integrated approach. This leads to a lack of access and use of quality reproductive health services and care among indigenous people and is one of several important factors contributing to high levels of maternal mortality and poor reproductive health among indigenous women. It is important to ensure that an intercultural approach is included in health policies, programs and services. An intercultural strategy fosters dialogue and respect among women, men, and decision-makers and can contribute to the realization of reproductive health rights and improvement of health outcomes. The debate continues on how to accelerate progress in public policies, health programs and health services. An intercultural approach to assure the health of indigenous women should be a key part of this discussion. Specific efforts are critical for obtaining better health outcomes for indigenous women and other vulnerable populations, if not progress will stagnate in the middle of the 21st century, jeopardizing the attainment of the Millennium Development Goal (MDGs).

  4. Key issues in transplant tourism.

    Akoh, Jacob A

    2012-02-24

    Access to organ transplantation depends on national circumstances, and is partly determined by the cost of health care, availability of transplant services, the level of technical capacity and the availability of organs. Commercial transplantation is estimated to account for 5%-10% (3500-7000) of kidney transplants performed annually throughout the world. This review is to determine the state and outcome of renal transplantation associated with transplant tourism (TT) and the key challenges with such transplantation. The stakeholders of commercial transplantation include: patients on the waiting lists in developed countries or not on any list in developing countries; dialysis funding bodies; middlemen, hosting transplant centres; organ-exporting countries; and organ vendors. TT and commercial kidney transplants are associated with a high incidence of surgical complications, acute rejection and invasive infection which cause major morbidity and mortality. There are ethical and medical concerns regarding the management of recipients of organs from vendors. The growing demand for transplantation, the perceived failure of altruistic donation in providing enough organs has led to calls for a legalised market in organ procurement or regulated trial in incentives for donation. Developing transplant services worldwide has many benefits - improving results of transplantation as they would be performed legally, increasing the donor pool and making TT unnecessary. Meanwhile there is a need to re-examine intrinsic attitudes to TT bearing in mind the cultural and economic realities of globalisation. Perhaps the World Health Organization in conjunction with The Transplantation Society would set up a working party of stakeholders to study this matter in greater detail and make recommendations.

  5. Ocean energy: key legal issues and challenges

    International Nuclear Information System (INIS)

    Ocean energy is a novel renewable energy resource being developed as part of the push towards a 'Blue Economy'. The literature on ocean energy has focused on technical, environmental, and, increasingly, social and political aspects. Legal and regulatory factors have received less attention, despite their importance in supporting this new technology and ensuring its sustainable development. In this Issue Brief, we set out some key legal challenges for the development of ocean energy technologies, structured around the following core themes of marine governance: (i) international law; (ii) environmental impacts; (iii) rights and ownership; (iv) consenting processes; and (v) management of marine space and resources.

    2012-04-01

    Full Text Available This article aimed to identify those issues that were present in global technological innovation projects carried out by Brazilian multinational companies and which performance criterions these undertakings met. We investigated 36 global technological innovation projects from Brazilian multinational enterprises through a web-survey. Findings show that these companies went beyond the traditional iron triangle to evaluate their technological efforts and considered additional performance dimensions such as customer satisfaction, business results, and preparation for the future. Results also show high degree of presence for issues emerging from the industry, moderate degree of presence for issues emerging from both the project and R&D activities, and low degree of presence for issues emerging from the headquarters, the subsidiaries, and the external environment. Further research is needed to find out if and how these issues influenced the performance of the global technological innovation projects studied.DOI:10.5585/gep.v3i1.72

    2012-01-01

    Risk analysis of key systems have become a growing topic late of because of the development of offshore structures. Equipment failures of offioading system and fire accidents were analyzed based on the floating production,storage and offioading (FPSO) features.Fault tree analysis (FTA),and failure modes and effects analysis (FMEA) methods were examined based on information already researched on modules of relex reliability studio (RRS).Equipment failures were also analyzed qualitatively by establishing a fault tree and Boolean structure function based on the shortage of failure cases,statistical data,and risk control measures examined.Failure modes of fire accident were classified according to the different areas of fire occurrences during the FMEA process,using risk priority number (RPN) methods to evaluate their severity rank.The qualitative analysis of FTA gave the basic insight of forming the failure modes of FPSO offioading,and the fire FMEA gave the priorities and suggested processes.The research has practical importance for the security analysis problems of FPSO.

    1994-10-01

    Whilst recognising that the reduction of poverty levels in developing countries takes precedence to the improvement and protection of the environment, the author comments that any efforts geared to fostering socioeconomic development will indirectly address the environment issue. The aims of a broad strategy and a more specific energy strategy geared at fostering sustainable development in Latin America are discussed. It is suggested that development of hydropower should continue, that the share of natural gas in the regional energy balance be increased and that efforts be put into increasing energy efficiency and improving utilization technologies. Promotion of energy projects that generate employment, promotion of projects for the use of biomass as an energy source, and implementation of a series of joint ventures are ideas advocated. Possibilities of cooperation between the Latin American Energy Organization (OLADE) and the Dutch government are aired.

    2015-12-01

    We present the key issues to consider in therapy with Muslim families. Following a brief introduction, five themes are presented: self, family dynamics, causation, and coping strategies. The section on "self" includes a discussion of three terms which link the four Islamic models of "self" identified through the review. The family dynamics section pays particular attention to interconnectedness, family roles, and gender. Causation is discussed with reference to supernatural and spiritual causes. On the theme of coping strategies, religious responses are discussed as are the roles of religious leaders, and professional mental health services. Clinical implications from the key themes are also discussed in addition to limitations of the published literature in this area. This includes a discussion of the epistemological and paradigmatic issues related to the research. The review concludes by summarising these issues and presenting areas for further research.

    Full Text Available As part of a longitudinal study of key information systems management issues, a survey of Australasia's largest 500 organisations was conducted to identify which issues were perceived by the IS executives as being important, problematic and critical over the next three to five years. The most critical issues were revealed to be a mix of technology management issues (IT infrastructure, communications, disaster recovery, strategic management issues (competitive advantage, IS planning, aligning the IS organisation, people management issues (organisational learning, educating senior management in IT, systems development and data management issues (effective use of the data resource, and end-user computing. This reflects the need for a balance of business, technical, and people skills in an IS executive. Non-critical issues were mostly related to systems development and the individual technologies which must be integrated and managed to ensure a responsive IT infrastructure. The study also reveals that some issues are much more important than problematic (disaster recovery, competitive advantage, information architecture, and IS alignment while others are much more problematic than important (end-user computing, IS role and contribution, and BPR. The former reflects a growing level of knowledge in handling these issues, while the latter reflects a continuing problem with them. The differences between this study and similar studies conducted in 1988 and 1992 show that there is a growing confidence in the IS executive's ability to manage the strategic issues, a continuing concern about providing a responsive IT infrastructure (especially communications, and a continuing concern with educating all 'customers' in the organisation in the effective use of IT, including senior management.

    In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program an updated scientific assessment has been conducted of the Arctic Freshwater System (AFS), entitled the Arctic Freshwater Synthesis (AFSΣ). The major reason behind the joint request was an increasing concern that changes to the AFS have produced, and could produce even greater, changes to biogeophysical and socioeconomic systems of special importance to northern residents and also produce extra-Arctic climatic effects that will have global consequences. The AFSΣ was structured around six key thematic areas: atmosphere, oceans, terrestrial hydrology, terrestrial ecology, resources, and modeling, the review of each coauthored by an international group of scientists and published as separate manuscripts in this special issue of Journal of Geophysical Research-Biogeosciences. This AFSΣ summary manuscript reviews key issues that emerged during the conduct of the synthesis, especially those that are cross-thematic in nature, and identifies future research required to address such issues.

    Marie JELINKOVA

    2007-04-01

    Full Text Available This paper aims to highlight some often occurring failures that need to be eliminated when attempting to develop an integral and efficient policy on labor migration. As an example, a brief overview of the development of immigration policies and its critical shortcomings in the Czech Republic is provided. Following this, the paper analyzes two aspects: the protection of migrant workers and the trafficking in human beings. In particular, the paper deals with three crucial issues of labor migration which are: (1 the inconsistent aims of immigration policies, (2 the client system, and (3 the dependence on middlemen. The paper also focuses on the role of state, police, and NGO’s in the trafficking in human beings and forced labor or labor exploitation in the Czech Republic. In addition, the legislation on forced labor and the possibilities of assistance to trafficked person are analyzed.By comparing various aspects of immigration policy, this paper covers some, but certainly not all, of the key issues concerning the process of immigrant integration. Several suggestions are made that could improve the situation of labor migrants in a significant way.

  10. Key issues on safety design basis selection and safety assessment

    International Nuclear Information System (INIS)

    In current fast reactor design in Japan, four design accident conditions and four design seismic conditions are adopted as the design base classifications. These are classified by the considerations on both likelihood of occurrence and the severeness of the consequences. There are several major problem areas in safety design consideration such as core accident problems which include fuel sodium interaction, fuel failure propagation and residual decay heat removal, and decay heat removal systems problems which is more or less the problem of selection of appropriate system and of assurance of high reliability of the system. In view of licensing, two kinds of accidents are postulated in evaluating the adequacy of a reactor site. The one is the ''major accident'' which is the accident to give most severe radiation hazard to the public from technical point of view. The other is the ''hypothetical accident'', induced public accident of which is severer than that of major accident. While the concept of the former is rather unique to Japanese licensing, the latter is almost equivalent to design base hypothetical accident of the US practice. In this paper, design bases selections, key safety issues and some of the licensing considerations in Japan are described

  11. Trends between 1973 and 1988: Summary and key issues

    International Nuclear Information System (INIS)

    The preceding chapters considered the evolution of activity, structure, energy intensity, and energy use between the early 1970s and 1988 for the manufacturing, transportation, residential, and service sectors. In this chapter, the author summarizes the changes that have taken place, and presents results of a cross-sectoral analysis of the effect of change in sectoral activity, structure, and energy intensity on energy use in the three largest OECD economies: the United States, Japan, and West Germany. He also addresses a number of key issues that have important implications for future energy use in the OECD countries and elsewhere. Between 1973 and 1988, final energy use in the five sectors studied (which account for around 90% of total energy use) grew by 3% in the United, States, 15% in Japan, and 3% in West Germany. Energy use in manufacturing declined by 10-20% in each country. Energy use for passenger travel grew by only 11% in the United States, but rose by 76% in Japan and by 56% in West Germany. There was moderate to strong growth in freight energy use in all three countries. There was very high growth in residential and services energy use in Japan, and moderate growth in these sectors in the United States and West Germany. 12 refs., 5 figs., 3 tabs

  13. Offshore wind power experiences, potential and key issues for deployment

    Energy Technology Data Exchange (ETDEWEB)

    Lemming, J.; Morthorst, P.E.; Clausen, Niels-Erik

    2009-01-15

    Wind power has been growing at spectacular rates. Today it is the largest non-hydro renewable power technology. Worldwide there is 74 GW of installed capacity which is 1.7% of power generation capacity and in 2006 it accounted for 0.82% of electricity production. However, offshore wind still only counts for a very small amount and development has only taken place in North European counties round the North Sea and the Baltic Sea over the last 15 years. Offshore wind is still some 50% more expensive than onshore wind, but more wind resources and lesser visual impacts from larger turbines are expected to compensate for the higher installation costs in the long term. Most offshore wind farms are installed in British, Swedish and Danish waters, and present-day costs of installing wind energy in the UK are between 1,200 to 1,600 GBP/kW (1,781 to 2,375 Euro/kW) offshore, while in Sweden investment costs were 1,800 Euro/kW, and in Denmark 1,200 to 1,700 Euro/kW, though investment costs for a new wind farm are expected be in the range of 2.0 to 2.2 mill. Euro/MW for a near-shore shallow depth facility. Future developments in offshore wind technology concerning aerodynamics, structural dynamics, structural design, machine elements, electrical design and grid integration could drive investment costs from present-day range of 1.9 to 2.2 mill. Euro/MW down to 1.35 - 1.54 mill.Euro/MW in 2050, which accounts for a reduction of costs of approx. 35%. In order to sum up progress and identify future research needs, the International Energy Agency (IEA) Wind agreement Task 11 should arrange a new meeting concerning long term research needs for reviewing 'the long term strategy for 2000 to 2020' from 2001, to come up with suggestions / recommendations on how to define and proceed with, the necessary research activities of the IEA Wind Agreement and governments involved on key wind issues related to offshore technologies.

  15. Practical issues in quantum-key-distribution post-processing

    CERN Document Server

    Fung, Chi-Hang Fred; Chau, H F

    2009-01-01

    Quantum key distribution (QKD) is a secure key generation method between two distant parties by wisely exploiting properties of quantum mechanics. In QKD, experimental measurement outcomes on quantum states are transformed by the two parties to a secret key. This transformation is composed of many logical steps (as guided by security proofs), which together will ultimately determine the length of the final secret key and its security. We detail the procedure for performing such classical post-processing taking into account practical concerns (including the finite-size effect and authentication and encryption for classical communications). This procedure is directly applicable to realistic QKD experiments, and thus serves as a recipe that specifies what post-processing operations are needed and what the security level is for certain lengths of the keys. Our result is applicable to the BB84 protocol with a single or entangled photon source.

  18. Economics issues - nuclear power generation in North America

    International Nuclear Information System (INIS)

    The structure of the US utility industry is in transition. Political, social, and economic factors are contributing to a rapid shift from a monopoly structure (captive markets, cost-plus prices, negotiated rate of return on capital) to a highly competitive one (choices for customers, prices determined by the market place, earnings based on market price less cost). The rate of change has been accelerating. For example, what just two years ago would have been thought of as highly unlikely -- competition for the individual electric customer -- is now part of the plan in California and other states. In our view, technology is at the root of many of these structural changes with more to come. Yet another round of technological change is afoot, involving even more efficient gas turbines, new methods of utilizing transmission lines, distributed generation, and new opportunities for electricity use and service. It can be argued that the restructuring of the marketplace reflects, in some measure, anticipation for these advances. For the foreseeable future, nuclear energy will continue to play a significant role in the generating grid of North America. However, new nuclear generation will be held to standards of competition that are dictated by market forces, and by advances in competing technologies for base load generation. It is important to understand these forces, and devise a response which ensures that nuclear energy will continue to provide a viable, competitive, and environmentally superior option for generating electricity in the 21st century. The EPRI Nuclear Power program is focused on achieving these goals. (author)

    MacDonald, D.D.; Knudsen, E.E.

    2004-01-01

    Many fisheries in North America are severely depleted and trending downwards. In an effort to find ways of reversing this disturbing situation, the American Fisheries Society and the Sustainable Fisheries Foundation invited leading experts in fisheries science and aquatic resource management to share their thoughts and insights in this book. These experts were asked to identify the factors that are currently impairing our ability to effectively manage fisheries resources and propose creative solutions for addressing the most challenging issues affecting fisheries sustainability. Based on the information that was provided by the experts (i.e., as presented in the earlier chapters of this book), it is apparent that a wide range of human activities are adversely affecting our shared fisheries resources and the aquatic habitats upon which they depend. The most challenging problems stem from causes that are largely beyond the scope of traditional fisheries management (e.g., human population growth, resource consumption patterns, global climate change, broad land-use patterns). It is also apparent that resolution of these challenges will require a new approach to fisheries management - one that effectively integrates economic, social, and environmental interests into a decision-making framework that supports fisheries sustainability. The key strategies for supporting such a transition toward a more holistic and comprehensive approach to managing the human activities that influence fisheries and aquatic resources are summarized in this chapter. ?? 2004 by the American Fisheries Society.

    Despite the economic growth in 1987 and 1988, there are three issues of concern: the strength of consumer spending, the risk of accelerating inflation, and the federal budget deficit. The history of recent consumer spending is reviewed, and the recommendation made that if the recent "binge" of 1987-1988 has caused the economy to overshoot its production capacity, monetary and fiscal policies should be adjusted to rein in the spending. Regarding inflation, despite projected productivity gains, the economy seems to be heading for a 4.5%-5.0% core rate of inflation, a rate that can surge to 1970s-like levels with any substantial bad news. The observation is made that no major sustained cut in financing costs will occur until U.S. fiscal policy is changed. Regarding the deficit, voters cannot seek more services without either higher taxes or higher interest rates; growth alone will not cure the federal deficit. The distinction between good and bad types of debt is made and the history and causes of the $ 2 trillion increase in federal debt between fiscal years 1980 and 1988 is reviewed. Corporate debt and the recent corporate acquisitions and leveraged buyouts are analyzed. Public policy considerations arise primarily from the need to limit the system risks imposed by the scale of the buyout mania and to insure fair treatment of current debt holders of target corporations. Greater regulation of pension investments may be necessary, and widespread use of change-of-ownership clauses in bonds would be productive. PMID:2923634

    Full Text Available Cloud computing is a harbinger to a newer era in the field of computing where distributed and centralized services are used in a unique way. In cloud computing, the computational resources of different vendors and IT services providers are managed for providing an enormous and a scalable computing services platform that offers efficient data processing coupled with better QoS at a lower cost. The on-demand dynamic and scalable resource allocation is the main motif behind the development and deployment of cloud computing. The potential growth in this area and the presence of some dominant organizations with abundant resources (like Google, Amazon, Salesforce, Rackspace, Azure, GoGrid, make the field of cloud computing more fascinating. All the cloud computing processes need to be in unanimity to dole out better QoS i.e., to provide better software functionality, meet the tenant’s requirements for their desired processing power and to exploit elevated bandwidth.. However, several technical and functional e.g., pervasive access to resources, dynamic discovery, on the fly access and composition of resources pose serious challenges for cloud computing. In this study, the performance issues in cloud computing are discussed. A number of schemes pertaining to QoS issues are critically analyzed to point out their strengths and weaknesses. Some of the performance parameters at the three basic layers of the cloud — Infrastructure as a Service, Platform as a Service and Software as a Service — are also discussed in this paper.

    Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This article provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: (1) Criterion A may benefit from some rewording, without changing its focus or meaning; (2) There are both advantages and disadvantages to adding a new criterion to reflect compulsive BDD behaviors; this possible addition requires further consideration; (3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; (4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV's criterion C are suggested; (5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; (6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; (7) Adding muscle dysmorphia as a specifier may have clinical utility; and (8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD's delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate article.

  10. Knowledge management - A key issue for EnBW

    International Nuclear Information System (INIS)

    Full text: The motivation for knowledge management can be summarised with the words of EnBW CEO Prof. Claassen, 2002 'knowledge manager of the year' in Germany: 'Against the backdrop of the ever-increasing complexity of strategic planning and activities on the operational front, knowledge management is a key factor in the long-term success of our business.' Professional knowledge management motivates and supports employees, helping to create networks in which they can lay the foundations for the future success of the company. It must be emphasised that knowledge management is the responsibility of management, and EnBW has established a suitable framework consisting of different action levels and goals: 1) Normative level (corporate culture): creating a knowledge-aware and knowledge-friendly corporate culture 2) Strategic level (human resources): systematic gearing of internal intangible potentials towards future requirements. 3) Operational level (information/communication): making the required knowledge available in the necessary scope and quality, in the right place and at the right time. If knowledge management can generally be seen as basic requirement for successful companies, then it is even more important for nuclear operators. Today, nuclear energy is an important generating technology in Europe, for Germany and for EnBW with major future potential, but a technology that must be employed with great caution and attaching top priority to safe operation. For nuclear operators, the rule is always 'safety first'. But knowledge management implemented and used in the right way can also enhance both safety and competitive operation of the plants at the same time. In this connection, successful knowledge management plays a key role due to the complex interplay of many different disciplines within a demanding legal and regulatory framework, the paramount importance of collective past experience and the high demands on the expertise of the employees operating nuclear

  11. Key issues in space nuclear power challenges for the future

    International Nuclear Information System (INIS)

    The future appears rich in missions that will extend the frontiers of knowledge, human presence in space, and opportunities for profitable commerce. Key to success of these ventures is the availability of plentiful, cost effective electric power and assured, low cost access to space. While forecasts of space power needs are problematic, an assessment of future needs based on terrestrial experience has been made. These needs fall into three broad categories: survival, self sufficiency and industrialization. The cost of delivering payloads to orbital locations from LEO to Mars has been determined and future launch cost reductions projected. From these factors, then, projections of the performance necessary for future solar and nuclear space power options has been made. These goals are largely dependent upon orbital location and energy storage needs. Finally the cost of present space power systems has been determined and projections made for future systems

    Full Text Available The article sets out to investigate the meaning, role and implications of some information management approaches used in Digital Library practice. A greater focus on innovation in managing online resources and on improving their interoperability can be achieved by normalizing metadata schemas through interoperable standards, world-wide accepted controlled vocabularies as well as by their enrichment through qualitatively constructed ontologies and linked data, which are key to the expansion of the semantic reasoning on the web through building and connection of additional semantic layers on top of metadata descriptions. Reviewing some innovative methods of information representation (LODe-BD, SWAP, the paper tries to lead the reader to discover some new ways of knowledge creation in digital information environment, in particular what concerns digital bibliographic records.

  13. Key issues and best practices in nuclear education

    International Nuclear Information System (INIS)

    The problems of the nuclear power sector that has faced with significant and exponentially growing demands for qualified personnel are analyzed. This is due to the simultaneous necessity for plant refurbishments and new nuclear power plant builds to meet increased energy needs. Additional expertise will be needed to cope with growing number of decommissioning projects needed to retire the ageing fleet of existing plants. The authors conclude that unless this situation is carefully managed, the nuclear industry is potentially at risk of serious consequences. In this context knowledge management is a key factor in assuring the sustainability of existing nuclear facilities, and the effective application of current knowledge to new design and construction projects, and development of innovative technology for future nuclear sector needs

  16. Key issues in the outlook for minerals and energy

    International Nuclear Information System (INIS)

    The outlook for Australia's minerals and energy sector continues to be positive because of the flow-on effects of economic growth in the newly industrialized Asia. The East Asian share of mineral and energy commodities continues to expand reflecting the growing demand for consumer goods and new economic and social infrastructure. Uncertainties in the minerals and energy outlook include the future economic performance of the developed countries and the former Soviet Union, trade and environmental issues and the effects of changing technology on minerals and energy production and consumption. Encouraged by good prospects for exploration success and firmer markets, real exploration expenditure is forecast to continue to rise and the volume of Australian mine production is expected to rise by 14 percent between 1995-6 and 2000-1. Export earnings from mineral and energy commodities are expected to rise by $5.6 billion Australian (16 percent) from 1995-6 levels to reach $41.9 billion in real terms by 2000-1.

    2006-06-01

    Hundreds of mirror segment, thousands of high precision actuators, highly complex mechanical, hydraulic, electrical and other technology subsystems, and extremely sophisticated control systems: an ELT system consists of millions of individual parts and components each of them may fail and lead to a partial or complete system breakdown. Component and system reliability does not only influence the acquisition costs of a product, it also defines the necessary maintenance work and the required logistic support. Taking the long operational life time of an ELT into account, reliability and maintainability are some of the main contributors to the system life cycle costs. Reliability and maintainability are key characteristics of any product and have to be designed into it from the early beginning; they can neither be tested into a product nor introduced by numerous maintenance activities. This presentation explains the interconnections between Reliability, Availability, Maintainability and Safety (RAMS) and outlines the necessary RAMS and Reliability Centered Maintenance (RCM) processes and activities during the entire life cycle of an ELT and an ELT instrument from the initial planning to the eventual disposal phase.

    The evolution of computer networks has experienced several major steps, and research focus of each step has been kept changing and evolving, from ARPANET to OSI/RM, then HSN (high speed network) and HPN (high performance network). During the evolution, computer networks represented by Internet have made great progress and gained unprecedented success. However, with the appearance and intensification of tussle, along with the three difficult problems (service customizing, resource control and user management) of modern network, it is found that traditional Internet and its architecture no longer meet the requirements of next generation network. Therefore, it is the next generation network that current Internet must evolve to. With the mindset of achieving valuable guidance for research on next generation network, this paper firstly analyzes some dilemmas facing current Internet and its architecture, and then surveys some recent influential research work and progresses in computer networks and related areas, including new generation network architecture, network resource control technologies, network management and security, distributed computing and middleware,wireless/mobile network, new generation network services and applications, and foundational theories on network modeling.Finally, this paper concludes that within the research on next generation network, more attention should be paid to the high availability network and corresponding architecture, key theories and supporting technologies.

    2015-04-01

    One of the greatest challenges in the fields of quantum information processing and quantum technologies is the detailed coherent control over each and every constituent of quantum systems with an ever increasing number of particles. Within this endeavor, harnessing of many-body entanglement against the detrimental effects of the environment is a major pressing issue. Besides being an important concept from a fundamental standpoint, entanglement has been recognized as a crucial resource for quantum speed-ups or performance enhancements over classical methods. Understanding and controlling many-body entanglement in open systems may have strong implications in quantum computing, quantum simulations of many-body systems, secure quantum communication or cryptography, quantum metrology, our understanding of the quantum-to-classical transition, and other important questions of quantum foundations.In this paper we present an overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement under the influence of noise. Entanglement is thus taken as a dynamic quantity on its own, and we survey how it evolves due to the unavoidable interaction of the entangled system with its surroundings. We analyze several scenarios, corresponding to different families of states and environments, which render a very rich diversity of dynamical behaviors.In contrast to single-particle quantities, like populations and coherences, which typically vanish only asymptotically in time, entanglement may disappear at a finite time. In addition, important classes of entanglement display an exponential decay with the number of particles when subject to local noise, which poses yet another threat to the already-challenging scaling of quantum technologies. Other classes, however, turn out to be extremely robust against local noise. Theoretical results and recent experiments regarding the difference between local and global decoherence are summarized.

This issue can be resolved by using a public-key cryptosystem, but mobile devices have limited computation ability and battery capacity and a PKI is needed. In this paper, we propose an efficient, non-PKI, authenticated, and blind issued symmetric key protocol for mobile access control systems. An easy-to-deploy authentication and authenticated key agreement system is designed such that empowered mobile devices can directly authorize other mobile devices to exchange keys with the server upon authentication using a non-PKI system without trusted parties. Empowered mobile users do not know the key value of the other mobile devices, preventing users from impersonating other individuals. Also, for security considerations, this system can revoke specific keys or keys issued by a specific user. The scheme is secure, efficient, and feasible and can be implemented in existing environments.

    Images are a critical part of the identification process because they enable direct, immediate and relatively unmediated comparisons between a specimen being identified and one or more reference specimens. The Carices Interactive Visual Identification Key (CIVIK) is a novel tool for identification of North American Carex species, the largest vascular plant genus in North America, and two less numerous closely-related genera, Cymophyllus and Kobresia. CIVIK incorporates 1288 high-resolution tiled image sets that allow users to zoom in to view minute structures that are crucial at times for identification in these genera. Morphological data are derived from the earlier Carex Interactive Identification Key (CIIK) which in turn used data from the Flora of North America treatments. In this new iteration, images can be viewed in a grid or histogram format, allowing multiple representations of data. In both formats the images are fully zoomable.

  12. Some Considerations Regarding the Key Issues of the Stiglitz-Sen-Fitoussi Report

    Directory of Open Access Journals (Sweden)

    BALTARETU Camelia

    2013-05-01

    Full Text Available This paper highlights the key issues of the Stiglitz-Sen-Fitoussi Report that was submitted in september 2009 by the Commission on the measurement of economic performance and social progress. As its name suggests, its focus is on the measurement of economic performance and social progress. The Report identified the limits of GDP as an indicator of economic performance and social progress showing in detail what is missing in current measures of economic performance and social progress. The key issues of the Stiglitz-Sen-Fitoussi Report are structured into three chapters based on the work of three working groups created by the Commission: Classical GDP issues, Sustainable development and environment and Quality of life. It also provided recommendations to better measure economic performance, societal well-being and sustainability.

  13. Decommissioning: Regulatory activities and identification of key organizational and human factors safety issues

    International Nuclear Information System (INIS)

    In the late 1990's the Swedish government decided to shut down Unit 1 of the Barsebaeck nuclear power plant. This report documents some of the efforts made by the Swedish Nuclear Power Inspectorate (SKI) to address human factors and organizational issues in nuclear safety during decommissioning of a nuclear facility. This report gives a brief review of the background to the decommissioning of Barsebaeck 1 and points out key safety issues that can arise during decommissioning. The main regulatory activities that were undertaken were requirements that the plant provide special safety reports on decommissioning focusing on first, the operation of both units until closure of Unit 1 and second, the operation of Unit 2 when Unit 1 was closed. In addition, SKI identified areas that might be affected by decommissioning and called these areas out for special attention. With regard to these areas of special attention, SKI required that the plant provide monthly reports on changing and emerging issues as well as self-assessments of the areas to be addressed in the special safety reports. Ten key safety issues were identified and evaluated with regard to different stages of decommissioning and with regard to the actions taken by Barsebaeck. Some key conclusions from SKI's experience in regulating a decommissioning nuclear power plant conclude the report

  2. The regional response to the greenhouse issue: Latin America and the Caribbean

    International Nuclear Information System (INIS)

    The increase in greenhouse gas emissions in Latin America and the Caribbean is not directly linked to energy consumption. It is estimated that about two-thirds of the carbon compounds that are emitted annually in the region and contribute to the greenhouse effect stem from the deforestation of 4 to 6 million hectares of forests destroyed annually by unplanned land settlement, migratory agriculture, and agribusiness. As a contribution to the debate on the global problem of the increasing greenhouse effect, the present article tries to analyze the specific regional characteristics of the problem, their relation to the global issue, and the regional options for decreasing carbon compound emissions. The developing countries, instead of waiting for the consequences of the 1- to 5-degree-Centrigrade increase in average temperature that is being forecast for the planet in the next 50 to 70 years, will have to deal with the possibility of seeing their land converted into ecological disaster areas where life cannot be sustained within the next 20 years. Within this context, technology can do very little, because deforestation basically is not a technological problem but rather has to do with the application of unsustainable development models that require profound economic and social changes

  3. Key technical issues associated with a method of pulse compression. Final technical report

    International Nuclear Information System (INIS)

    Key technical issues for angular multiplexing as a method of pulse compression in a 100 KJ KrF laser have been studied. Environmental issues studied include seismic vibrations man-made vibrations, air propagation, turbulence, and thermal gradient-induced density fluctuations. These studies have been incorporated in the design of mirror mounts and an alignment system, both of which are reported. A design study and performance analysis of the final amplifier have been undertaken. The pulse compression optical train has been designed and assessed as to its performance. Individual components are described and analytical relationships between the optical component size, surface quality, damage threshold and final focus properties are derived. The optical train primary aberrations are obtained and a method for aberration minimization is presented. Cost algorithms for the mirrors, mounts, and electrical hardware are integrated into a cost model to determine system costs as a function of pulse length, aperture size, and spot size

  4. Integrating Variable Renewable Energy into the Grid: Key Issues, Greening the Grid (Spanish Version)

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    This is the Spanish version of 'Greening the Grid - Integrating Variable Renewable Energy into the Grid: Key Issues'. To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, and Planning for a High RE Future.

  5. Beaufort Sea oil spills state of knowledge review and identification of key issues

    International Nuclear Information System (INIS)

    From the 1960s to the 1980s, offshore petroleum exploration activities were carried out by several companies in the Canadian Arctic and important resources of oil and gas were discovered. These reserves have not been exploited until now, but exploration activities are expected to increase in the coming years due to changing market conditions and to result in greater risks of accidental spills. The aim of this report is to review existing knowledge of oil spills in Arctic waters, identify the associated issues and provide a reference document for the stakeholders. A literature review of the subject was carried out by the study team using online database search services, in-house libraries and Environment Canada's library. In addition, the study team held a workshop in October 2009 to present their findings and discuss key issues with stakeholders. This document provides the findings of the study team.

  13. The sustainable use of tropical coastal resources - A key conservation issue

    International Nuclear Information System (INIS)

    The three papers covered in this review form a series, addressing broadly the same issues in increasing detail. The paper by Carl Gustaf Lundin and Olof Linden, on 'Coastal ecosystems: Attempts to manage a threatened resource', takes a wide view of the coastal zones (the regions between the seaward margins of the continental shelves, in water depths of around 200 m and the landward edge of the coastal plains at a comparable altitude above mean sea level), and the nature of the pressures upon them. The paper by Magnus A.K. Ngoile and Chris J. Horrill, on 'Coastal ecosystems productivity and ecosystem protection: Coastal ecosystem management', focuses very much on these same issues of use and pressure in the Eastern Africa Region. The paper by M.C.Oehman, A. Rajasuriya and O. Linden, on 'Human disturbances on coral reefs in Sri Lanka: A case study' looks in some depth at the situation on three selected reef systems in the one country. All the papers address the key question of how the management of coastal resources should change, in order to avoid continuing degradation and the cost and impoverishment it is likely to bring. The three papers mentioned is published in this issue of Ambio, p. 461-480

    2012-01-01

    A survey of global health experts attending an invited meeting provided a means to map key issues perceived to be shaping emerging global public health agendas. Eighty-five participants proposed three major issues likely to have the most significant impact on the field of global health in the coming years. Six raters grouped the resultant items, with multi-dimensional scaling (MDS) analysis producing a composite two-dimensional map depicting the overall patterning of items. Thematic clusters were incorporated within four major domains: changing health and prevention needs (15% of items), globalisation and global health governance (33% of items), transforming health systems (30% of items) and innovations in science and technology (7% of items). The remaining 15% of items addressed forms of environmental change. The distribution of items across domains was not significantly influenced by the current professional role of participants, their current location in the 'global north' or 'global south' or their region of focus (although the latter approached threshold significance). The constraints on interpretation imposed by the biases influencing participation in the survey are noted. However, the exercise suggests the potential for coherently defining shared agendas for diverse stakeholders to address emerging priorities. The closer integration of environmental concerns with other global public issues is clearly warranted. PMID:22765282

  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.

  16. Key issues in life cycle assessment of ethanol production from lignocellulosic biomass: Challenges and perspectives.

    Science.gov (United States)

    Singh, Anoop; Pant, Deepak; Korres, Nicholas E; Nizami, Abdul-Sattar; Prasad, Shiv; Murphy, Jerry D

    2010-07-01

    Progressive depletion of conventional fossil fuels with increasing energy consumption and greenhouse gas (GHG) emissions have led to a move towards renewable and sustainable energy sources. Lignocellulosic biomass is available in massive quantities and provides enormous potential for bioethanol production. However, to ascertain optimal biofuel strategies, it is necessary to take into account environmental impacts from cradle to grave. Life cycle assessment (LCA) techniques allow detailed analysis of material and energy fluxes on regional and global scales. This includes indirect inputs to the production process and associated wastes and emissions, and the downstream fate of products in the future. At the same time if not used properly, LCA can lead to incorrect and inappropriate actions on the part of industry and/or policy makers. This paper aims to list key issues for quantifying the use of resources and releases to the environment associated with the entire life cycle of lignocellulosic bioethanol production. PMID:20015644

    Quinn, Emma; Jit, Mark; Newall, Anthony T

    2014-06-01

    Evidence has shown that quadrivalent influenza vaccines containing all four subtypes are safe and immunogenic. However, to date there have been few published studies exploring the population-level clinical and economic impact of quadrivalent compared to trivalent influenza vaccines. Economic evaluation studies need to be conducted in order to inform country-level decision making about whether (and how to) introduce and replace the current trivalent influenza vaccines with quadrivalent influenza vaccination programs. Several key issues associated with estimating the clinical and economic impact of the trivalent versus quadrivalent vaccines are discussed in this article, particularly the complexities involved in estimating the incremental preventable disease and economic burden. Other factors, such as the indirect (herd) protection from quadrivalent influenza vaccination and the timing of the replacement of trivalent influenza vaccination programs are also discussed.

  19. Multiple-Robot Systems for USAR: Key Design Attributes and Deployment Issues

    Directory of Open Access Journals (Sweden)

    Choon Yue Wong

    2011-03-01

    Full Text Available The interaction between humans and robots is undergoing an evolution. Progress in this evolution means that humans are close to robustly deploying multiple robots. Urban search and rescue (USAR can benefit greatly from such capability. The review shows that with state of the art artificial intelligence, robots can work autonomously but still require human supervision. It also shows that multiple robot deployment (MRD is more economical, shortens mission durations, adds reliability as well as addresses missions impossible with one robot and payload constraints. By combining robot autonomy and human supervision, the benefits of MRD can be applied to USAR while at the same time minimizing human exposure to danger. This is achieved with a single-human multiple-robot system (SHMRS. However, designers of the SHMRS must consider key attributes such as the size, composition and organizational structure of the robot collective. Variations in these attributes also induce fluctuations in issues within SHMRS deployment such as robot communication and computational load as well as human cognitive workload and situation awareness (SA.Research is essential to determine how the attributes can be manipulated to mitigate these issues while meeting the requirements of the USAR mission.

  20. Family-friendliness in business as a key issue for the future.

    Science.gov (United States)

    Stutzer, Erich

    2012-01-01

    These days family-friendliness is a key issue for the future of businesses. Investments in a family conscious personnel policy are considered as forward-looking decisions in companies. This happens against the background of a sustainable personnel policy in times of a decrease in the number of employable persons, an increasing shortage of skilled workers and an ageing workforce. Family-friendly working conditions are becoming a key factor in the competition for staff. When choosing an employer, family-friendliness has become a crucial topic. Employment participation and skills of women, especially of mothers, have greatly increased. To facilitate the realisation of their wish to return to paid employment, however, measures to reconcile work and family are required. Family-conscious measures have been proven to lead to higher employee productivity. Job satisfaction and motivation of employees and accumulation of human capital increase, absenteeism declines, the return of investment rises. Fields of activity for family-friendly measures in companies range from working arrangements, parental leave and re-entry programmes and various child care offers to services for families. In connection with the demographic development the demand for a better reconciliation of work and elder care should in future become ever more important, just as the upkeep of the occupational skills and working capacity of an ageing workforce. Family-friendliness has to become an integral part of corporate culture.

    2015-04-01

    Costa Rica is located on the Central American Isthmus, which receives direct moisture inputs from the Caribbean Sea and the Pacific Ocean. The relatively narrow, but high relief Central American land bridge is characterized by unique mountainous and lowland microclimates. However, only limited knowledge exists about the impact of relief and regional atmospheric circulation patterns on precipitation origin, transport, and isotopic composition in this tropical region. Therefore, the main scope of this study is to identify the key drivers controlling variations in meteoric waters of Costa Rica using stable isotopes based on daily sample collection for the year 2013. The monitoring sites comprise three strategic locations across Costa Rica: Heredia (Central Valley), Turrialba (Caribbean slope), and Caño Seco (South Pacific slope). Sporadic dry season rain is mostly related to isolated enriched events ranging from -5.8‰ d18O up to -0.9‰ d18O. By mid-May, the Intertropical Convergence Zone reaches Costa Rica resulting in a notable depletion in isotope ratios (up to -18.5‰ d18O). HYSPLIT back air mass trajectories indicate the strong influence on the origin and transport of precipitation of two main moisture transport mechanisms, the Caribbean Low Level Jet and the Colombian Low Level Jet as well as localized convection events. Multiple linear regression models constructed based on Random Forests of surface meteorological information and atmospheric sounding profiles suggest that Lifted Condensation Level and surface relative humidity are the main factors controlling isotopic variations. These findings diverge from the recognized 'amount effect' in monthly composite samples across the tropics. Understanding of stable isotope dynamics in tropical precipitation can be used to enhance catchment and groundwater modeling efforts in ungauged basins where scarcity of long-term monitoring data drastically limit current and future water resources management.

    In ACM'CCS 2009,Camenisch,et al.proposed the Obhvious Transfer with Access Control (AC-OT) in which each item is associated with an attribute set and can only be available,on request,to the users who have all the attributes in the associated set.Namely,AC-OT achieves access control policy for conjunction of attributes.Essentially,the functionality of AC-OT is equivalent to the simplified version that we call AC-OT-SV:for each item,one attribute is associated with it,and it is requested that only the users who possess the associated attribute can obtain the item by queries.On one hand,AC-OT-SV is a special case of AC-OT when there is just one associated attribute with each item.On the other hand,any AC-OT can be realized by an AC-OT-SV.In this paper,we first present a concrete AC-OT-SV protocol which is proved to be secure in the model defined by Camenisch,et al..Then from the protocol,interestingly,a concrete Identity-Based Encryption (IBE) with Anonymous Key Issuing (AKI) is given which is just a direct application to AC-OT-SV.By comparison,we show that the AKI protocol we present is more efficient in communications than that proposed by Chow.

    Primary objectives of our work were to spatially delineate post industrial areas of the EU-27 and indicate key environmental, social and economic sensitivity issues for these regions. The density of industrial sites within NUTS-x regions for EU-27 countries was assessed by using CORINE 2000 land cover layer. A development of postindustrial society in Europe represents a strong geographic diversity. There are distinct historical and current differences between regions which form major groups, comprising similar internal characteristics and definable trends in environmental and socioeconomic sense. Regions grouped into postindustrial clusters are fundamentally different from the European average, and are facing specific problems related to global market and political changes. Eastern postindustrial regions can be characterized as socially and economically weak, exhibiting high unemployment rate, low GDP, negative population growth and a strong environmental pressure, represented by a high density of dump sites. Most of the western EU postindustrial areas have been successfully recovered and moved into new economy as shown by most of the indicators. In urban postindustrial zones, however, emission sources of pollutants seem to continually be a major problem--not necessarily in terms of exceeding thresholds, but through a remarkable difference in the amount of pollutants produced relative to other regions.

  7. Key Durability Issues with Mullite-Based Environmental Barrier Coatings for Si-Based Ceramics

    Science.gov (United States)

    Lee, Kang N.

    2000-01-01

    Plasma-sprayed mullite (3Al2O3.2SiO2) and mullite/yttria-stabilized-zirconia (YSZ) dual layer coatings have been developed to protect silicon -based ceramics from environmental attack. Mullite-based coating systems show excellent durability in air. However, in combustion environments, corrosive species such as molten salt or water vapor penetrate through cracks in the coating and attack the Si-based ceramics along the interface. Thus the modification of the coating system for enhanced crack-resistance is necessary for long-term durability in combustion environments. Other key durability issues include interfacial contamination and coating/substrate bonding. Interfacial contamination leads to enhanced oxidation and interfacial pore formation, while a weak coating/substrate bonding leads to rapid attack of the interface by corrosive species, both of which can cause a premature failure of the coating. Interfacial contamination can be minimized by limiting impurities in coating and substrate materials. The interface may be modified to improve the coating/substrate bond.

    Full Text Available Biotechnology or the engineering of the genetic material of species can give way to avenues of possibilities for the benefit of people, fauna and flora but also has the potential of posing untold and undiscovered threats to human beings and other living organisms. One of the first attempts to legislate on international rules on biotechnology can be traced back to article 19 of the Convention on Biological Diversity (CBD in 1992. The CBD is indeed the first international legal instrument apart from the then European Community’s relevant directives to suggest that biotechnology is a matter of concern for the international community while providing a basis upon which more detailed procedures would be elaborated in the field of biosafety. While the CBD includes international rules on access to genetic resources, access to and the transfer of technology, the handling of biotechnology and the distribution of its benefits, it does not include a detailed regulation on genetically modified organisms (GMOs and their possible adverse effects on the environment, human and animal health. It was only with the coming into existence of the Cartagena Protocol on Biosafety (Cartagena Protocol to the CBD in 2000 that the safe transfer, handling and use of living modified organisms (LMOs such as genetically engineered plants, animals, and microbes were at last being catered for, albeit leaving aside the broader categories of GMOs. Due to the need for the negotiators of this protocol to make compromises, there were still key issues on the international biosafety framework pertaining mainly to the scope of the GMOs to be covered by this protocol and by the Advanced Informed Agreement procedure; identification and traceability issues; and liability and redress issues. Nine years after the entry into force of the Cartagena Protocol the transboundary movements of GMOs have clearly increased with new categories of GMOs and genetically modified products to regulate.

    Year 2000 will be remembered as an epoch making period between two Koreas. Korean nuclear industries became activated with the KEDO LWR main contracts entering into force in February, 2000. Respective design, manufacturing and construction activities are mobilized in accordance with the total project schedule of about 100 months. What started out as the nuclear power plant design standardization project in the early '80s, is now being implemented as repeat construction of KSNPs at Yonggwang and Ulchin sites as well as at Kumho site in the DPRK. However, the KEDO construction schedule and the past nuclear inconsistency issues are closely linked due to the nonproliferation concerns. In practice, the IAEA must come to the conclusion that the correctness and completeness must be fulfilled before delivery of the first key component for the KEDO LWR unit 1. While the IAEA verification process tends to focus on the nuclear materials accountancy control, longer term objective between two Koreas is bound to take the form of confidence building. It is necessary to analyse the nuclear research and production facilities in order to make proper evaluation of a nation's nuclear capabilities. Close assessment on development status of graphite moderated reactors and their operation history, spent fuel reprocessing facilities, and HEU production capabilities would be essential. In addition, illicit trafficking possibilities should be addressed. Chapter 1 describes the graphite moderated reactors in general; Chapter 2 describes various reprocessing processes and their detection capabilities; Chapter 3 contains possible uranium enrichment processes with their detection capabilities, and Chapter 4 summarizes the international treaties in illicit trafficking control with the IAEA database.

  11. Key Issues on Nuclear Energy Non-proliferation in East Asia

    International Nuclear Information System (INIS)

    Energy demand in East Asia casts a significant challenge to sustainable economy development and socio-political stability in the region which has experienced tensions throughout the history. The energy demand in this region has been dramatically increased since the start of reform in PRC. DPRK is another challenge. The current electricity consumption in DPRK is around 10% of that in ROK. If the economy of PRC continuously grows to the level of neighboring states and if the living standard of DPRK reaches that of ROK, the energy and electricity demand in the region will certainly be out of control unless the proper measures are taken into actions from today. The only feasible energy option is the nuclear one. PRC already proclaimed its ambitious plan to deploy more than 30 reactors in the near future. In addition, a couple of the South Eastern Asian states expressed their willingness to introduce nuclear power plants in the future. The increase in the use of nuclear energy is expected to bring up the nuclear renaissance in the region. However, without the proper mechanisms to supply fresh fuels and to manage spent nuclear fuels with full compliance of nuclear energy nonproliferation, the new development will inevitably cause the instability in the region. So far many interesting proposals on nuclear cooperation in East Asia were announced. Unfortunately, none of them works out properly yet, partly because the old proposals were too political. To restart the engine of the nuclear cooperation and nonproliferation in the region, it is necessary to find out what would be the common interests of the region not so much related to politics. In this paper, some key technical issues are addressed for future regional joint studies

    Energy Technology Data Exchange (ETDEWEB)

    Siddayao, Corazon M. (World Bank Washington, DC (USA). Economic Development Institute)

    1992-03-15

    Energy investments imply changes in the physical, social, and economic environment. Hence, both the short-term and the long-term costs and benefits of these investments must be taken into account. These changes may affect not only the immediate environment of the investment site but may extend geographically far beyond national borders as well as beyond the lifetimes of the people for whom the investments are intended. This paper reviews the issues relevant to developing countries. General conceptual and policies issues are discussed. Issues about the measurement of costs and benefits (including issues of 'sustainability' and the internalization of externalities resulting from environmental changes) as well as the role of opportunity costs in deciding a country's energy investment strategies are raised. The macroeconomic and institutional issues relevant to environmental impacts that might be incorporated in energy planning are suggested. The paper is based on a presentation to the 'Workshop on energy investments and the environment'. 24 refs., 1 fig.

    2009-01-01

    E-waste, a relatively recent addition to the waste stream in the form of discarded electronic and electric equipment, is getting increasing attention from policy makers as the quantity being generated is rising rapidly. One of the most promising policy options to address this issue is to extend the producers responsibility for their products beyond the point of sale, until end-of-product-life. This paper briefly introduces the concept of extended producer responsibility (EPR) and its applicability in the area of the end-of-life management of electronic and electrical equipment (EEE). It then examines the decade-long experience of Switzerland in using EPR to manage its e-waste, elaborating on the experience of the Swiss system in overcoming specific issues, and finally wrapping up with a synopsis of the lessons for policy makers. We consider each issue as an enquiry of questions confronting a policy maker and the choices that may present themselves. The five issues discussed are: (i) the challenges in getting an EPR based system started; (ii) securing financing to ensure a self-sustaining and smooth functioning system; (iii) organising a logistics network for the take back and collection of the e-waste; (iv) ensuring compliance of the various actors involved; and finally (v) reducing the threat of monopolistic practices.

    Full Text Available As an answer to the international tax evasion problem, the U.S. Congress issued the Foreign Account Tax Compliance Act – Fatca. This Act aims to promote tax compliance among citizens and U.S. residents holding foreign bank accounts. To this effect, Fatca requires Foreign Financial Institutions to enter into an agreement with the Internal Revenue Service (IRS to provide the IRS information about the identity and the status of the bank accounts held by US persons. Entities not willing to enter into an agreement with the IRS will be subject to a 30% withholding on U.S. sourced income regardless of whether the income is tax exempt. The application of this Act in our country brings a lot of concern regarding some issues, such us extraterritoriality, bank secrecy, the application of civil and criminal law. Since the effective date of implementation of Fatca is July 1, 2014, we understand that an official opinion concerning these issues and the possibilityto enter into an Intergovernmental Agreement with the U.S. government will be forthcoming in the following months.

    The large carrier frequency shift caused by the high-speed movement of satellite (Doppler effects) and the propagation delay on the up-down link are very critical issues in an LEO satellite communication system, which affects both the selection and the implementation of a suitable access method. A Doppler based multiple access technique is used here to control the flow and an MPRMA-HS protocol is proposed for the application in LEO satellite communication systems. The extended simulation trials prove that the proposed scheme seems to be a very promising access method.

    Effective symposia need two strong legs to stand upon: informative presentations of recent research paired with lively discussion of these topics. Although it is easy for the organizers of a symposium to predict the usefulness of the former, as they select the speakers and their topic areas, guaranteeing productive discussion is a far more difficult task. For the Crop Composition Workshop sponsored by the International Life Sciences Institute's Committee on Food and Biotechnology (ILSI IFBIC), the organizers scheduled four roundtable discussions with preselected questions and with rapporteurs drawn from governmental organizations and public-sector research institutes (the authors). It was also the organizers' intent to let these discussions flow on the basis of the experiences of the participants and pressing issues within the overall debate on the role of crop compositional analysis within safety assessment of biotechnology as it exists now and in the future. The goal of this perspective is to summarize the issues raised, providing references when possible, and to describe the consensus statements reached through the course of these discussions.

  5. Procuring, maintaining and using equipment: the key issues in controlling exposure to patients

    International Nuclear Information System (INIS)

    Radiological equipment is not purpose-built for each individual application. Thus, not only are acceptance criteria directly related to the design of equipment and the quality assurance exercised during its manufacture, but also the performance, safety and reliability of equipment must feature in the requirements for procuring new equipment. In the UK this issue is dealt with under the Department of Health and Social Security Manufacturer Registration Scheme for Medical Equipment in its application to radiological equipment. Similarly the continuing reliability of equipment in service is directly related to the quality of maintenance services. This is determined largely by the manner in which such services are procured. In the UK this issue has been considered by one of four Working Parties commissioned by the South-East Thames Regional Health Authority who are the ''Centre of Responsibility'' for diagnostic imaging equipment. The report prepared from the first phase of activity of this working group describes features of a procurement specification for maintenance services and prescribes the complementary duties of contractors and customers. The use in X-ray departments of the kind of manufacturing quality system that is used by most reputable equipment manufacturers has the potential for a dramatic reduction in exposure to patients.

    2015-05-01

    To foster sustainable, low-emission development, many countries are establishing ambitious renewable energy targets for their electricity supply. Because solar and wind tend to be more variable and uncertain than conventional sources, meeting these targets will involve changes to power system planning and operations. Grid integration is the practice of developing efficient ways to deliver variable renewable energy (VRE) to the grid. Good integration methods maximize the cost-effectiveness of incorporating VRE into the power system while maintaining or increasing system stability and reliability. When considering grid integration, policy makers, regulators, and system operators consider a variety of issues, which can be organized into four broad topics: New Renewable Energy Generation, New Transmission, Increased System Flexibility, Planning for a High RE Future.

  7. Adapting planning and scheduling concepts to an engineering perspective: Key issues and successful techniques

    International Nuclear Information System (INIS)

    Traditional approaches to engineering planning are slanted toward the formats and interests of downstream implementation, and do not always consider the form and criticality of the front-end engineering development process. These processes and scopes are less defined and more subjective than most construction and operations tasks, and require flexible scheduling methods. This paper discusses the characteristics and requirement of engineering schedules, presents concepts for approaching planning in this field, and illustrates simple methods for developing and analyzing engineering plans, and evaluating schedule performance. Engineering plans are structured into a schedule hierarchy which delineates appropriate control and responsibilities, and is governed by key evaluation and decision milestones. Schedule risk analysis considers the uncertainty of engineering tasks, and critical resource constraints. Methods to evaluate schedule performance recognize that engineers and managers are responsible for adequate planning and forecasting, and quality decisions, even if they cannot control all factors influencing schedule results

    Living systems have to constantly sense their external environment and adjust their internal state in order to survive and reproduce. Biological systems, from as complex as the brain to a single E. coli cell, have to process these data in order to make appropriate decisions. How do biological systems sense external signals? How do they process the information? How do they respond to signals? Through years of intense study by biologists, many key molecular players and their interactions have been identified in different biological machineries that carry out these signaling functions. However, an integrated, quantitative understanding of the whole system is still lacking for most cellular signaling pathways, not to say the more complicated neural circuits. To study signaling processes in biology, the key thing to measure is the input-output relationship. The input is the signal itself, such as chemical concentration, external temperature, light (intensity and frequency), and more complex signals such as the face of a cat. The output can be protein conformational changes and covalent modifications (phosphorylation, methylation, etc), gene expression, cell growth and motility, as well as more complex output such as neuron firing patterns and behaviors of higher animals. Due to the inherent noise in biological systems, the measured input-output dependence is often noisy. These noisy data can be analysed by using powerful tools and concepts from information theory such as mutual information, channel capacity, and the maximum entropy hypothesis. This information theory approach has been successfully used to reveal the underlying correlations between key components of biological networks, to set bounds for network performance, and to understand possible network architecture in generating observed correlations. Although the information theory approach provides a general tool in analysing noisy biological data and may be used to suggest possible network architectures in

    This book provides an analysis of the issues surrounding international resources and inspiring accounts of industrial best practices. The book consists of two distinct parts. The first part of the book brings together the results of years of research into the geopolitical, economic and ecological dimensions of material scarcity and resource efficiency. Chapter 2 discusses the main challenges and constraints related to the use of energy resources, water and land, industrial and metallic minerals, construction minerals and biotic resources, including water use and ecosystem degradation. The chapter also addresses important linkages between these various resources. Chapter 3 describes the international trends that are shaping the geopolitics of natural resources and looks at the implications for Europe and the Netherlands. Chapter 4 presents a wide range of strategies by which governments, producers and consumers may contribute to the more sustainable use of natural resources. The second part of the book describes 21 inspiring best practices in resource efficiency in a variety of industrial sectors. Based on a series of interviews with industrial pioneers, these chapters relate their first-hand experiences in improving resource efficiency. These business cases demonstrate that innovation and entrepreneurship can result in substantial improvements in resource efficiency. Chapter 5 focuses on best practices in the built environment, where substantial amounts of energy and minerals are used. Chapter 6 presents four ambitious strategies to promote sustainable food production and consumption. Chapter 7 describes recent developments in the chemical process industry, which produces most of the ingredients, compounds and semi-products for the vast range of products used by society. Chapter 8 provides four examples of the state-of-the-art in resource efficiency in the metal and high-tech industries. This chapter presents four business cases highlighting the benefits of the

  12. Toward a national policy for managing low-level radioactive waste: key issues and recommendations

    International Nuclear Information System (INIS)

    The Conservation Foundation, a not-for-profit research and public education organization, asked individuals with diverse backgrounds and viewpoints to come together under Foundation leadership as a Dialogue Group on Low-Level Radioactive Waste Management. The group, including persons who represent waste generators, concerned citizens, state regulators, and environmentalists, met over an 18-month period to discuss issues crucial to the development of a national policy on low-level wastes. The Dialogue Group agreed that three principles, if accepted broadly, would form the basis of a sound national policy for managing low-level radioactive wastes: with proper implementation, technology exists to manage low-level waste safely; generators and their customers should pay disposal costs; and greater public involvement at all stages can improve the disposal system. These principles acted as polestars for the group as it worked toward a series of policy recommendations in four main areas: (1) cleaning up closed commercial sites; (2) remodeling a system for defining and classifying low-level radioactive waste; (3) siting new low-level waste disposal facilities; and (4) decommissioning, long-term care, and liability. This report presents an extensive discussion of these recommendations covering qualifications, limitations, and alternatives

    The Severn Estuary and Bristol Channel encompass a number of designated sites supporting populations of waterbirds and seabirds that are of national or international importance, including the Severn Estuary and Burry Inlet Special Protection Areas (SPAs)/Ramsar Sites and Carmarthen Bay, the UK's first marine SPA. Here, we provide an overview of the present numbers and trends of the waterbirds and seabirds using these sites, updating previous reviews undertaken prior to these designations. We further provide a summary of the main issues that have affected the status of the area's bird populations. Declines in the numbers of waders on the Severn Estuary and the southwest over the last two decades have been linked to climate change. The Sea Empress oil-spill impacted both breeding seabirds and the wintering Common Scoters in Carmarthen Bay, though numbers of the latter recovered 3years after the spill. At the Burry Inlet, Oystercatcher numbers have fallen over the last 25years and considerable research has been undertaken into the conflict with cockle and mussel fisheries. A long-term study at Cardiff Bay, at the mouth of the Severn, revealed a significant impact on the survival of Redshanks following its impoundment and has helped to further understanding of responses of waterbirds to estuarine habitat loss. The potential impacts of the construction of a tidal power scheme on the Severn Estuary are also discussed. PMID:20153484

  14. Marketing electricity: Alberta review raises key issues for a sustainable energy policy

    International Nuclear Information System (INIS)

    Since 1982, generation and transmission costs incurred by Alberta's three largest electric utilities have been equalized through a mechanism implemented by the Electric Energy Marketing (EEM) Act. Although this scheme has been successful in providing uniform electricity rates across the province, it has been criticized and the provincial government has consequently announced a review of the EEM program. The terms of the review include examination of the validity of EEM objectives, the implementation of EEM, and alternatives to EEM. It is suggested that these terms are insufficient, and an approach to the EEM review is presented that would begin to ensure that essential issues related to sustainable energy policy are discussed. The approach indicates that a future electric utility industry would be more decentralized and that the EEM program as currently implemented may hinder such a development. It is also argued that full-cost pricing of electricity is more concordant with a sustainable energy policy. However, there may be a role for an EEM agency in a restructured electricity industry that includes a truly competitive generating sector. 13 refs

    Full Text Available Rising food costs can have major impact on vulnerable households, pushing those least able to cope further into poverty and hunger. On the other hand, provided appropriate policies and infrastructure are in place, higher agricultural prices can also raise farmers′ incomes and rural wages, improve rural economies and stimulate investment for longer-term economic growth. High food prices since 2007 have had both short-term impacts and long-term consequences, both good and bad. This article reviews the evidence of how rising costs have affected global food security since the food price crisis of 2007-2008, and their impact on different categories of households and countries. In light of recent studies, we know more about how households, and countries, cope or not with food price shocks but a number of contentious issues remain. These include the adequacy of current estimates and the interpretation of national and household food and nutrition security indicators. India is a particularly important country in this regard, given the high number of food insecure, the relative weight of India in global estimates of food and nutrition insecurity, and the puzzles that remain concerning the country′s reported declining per capita calorie consumption. Competing explanations for what is behind it are not in agreement, but these all point to the importance of policy and programme innovation and greater investment necessary to reach the achievable goal of food and nutrition security for all.

    2016-01-01

    Full Text Available The present review provides information relevant to issues and challenges in MEMS testing techniques that are implemented to analyze the microelectromechanical systems (MEMS behavior for specific application and operating conditions. MEMS devices are more complex and extremely diverse due to the immersion of multidomains. Their failure modes are distinctive under different circumstances. Therefore, testing of these systems at device level as well as at mass production level, that is, parallel testing, is becoming very challenging as compared to the IC test, because MEMS respond to electrical, physical, chemical, and optical stimuli. Currently, test systems developed for MEMS devices have to be customized due to their nondeterministic behavior and complexity. The accurate measurement of test systems for MEMS is difficult to quantify in the production phase. The complexity of the device to be tested required maturity in the test technique which increases the cost of test development; this practice is directly imposed on the device cost. This factor causes a delay in time-to-market.

  18. Tritium retention in candidate next-step protection materials: Engineering key issues and research requirements

    International Nuclear Information System (INIS)

    Although a considerable volume of valuable data on the behavior of tritium in beryllium and carbon-based armors exposed to hydrogenic fusion plasmas has been compiled over the past years both from operation of present-day tokamaks and from laboratory simulations, knowledge is far from being complete and tritium inventory predictions for these materials remain highly uncertain. In this paper the authors elucidate the main mechanisms responsible for tritium trapping and release in next step D-T tokamaks, as well as the applicability of some of the presently known database for design purposes. Due to their strong anticipated implications on the design, attention is focused mainly on codeposition and neutron damage effects. Some preliminary quantitative estimates are presented based on most recent experimental findings and latest modeling developments as well. The influence of important working conditions such as target temperature, loading particle fluxes, erosion and redeposition rates, as well as material characteristics such as the type of morphology of the protection material (i.e., amorphous plasma-sprayed beryllium vs. solid forms), and design dependent parameters are discussed in this paper. Remaining issues which require additional effort are identified

  20. The crisis in access to essential medicines in India: key issues which call for action.

    2013-01-01

    The government is planning to introduce free generic and essential medicines in public health facilities. Most people in India buy healthcare from the private sector, a compulsion that accounts for a high proportion of healthcare-related expenditure. To reduce the burden of healthcare costs, the government must improve availability and affordability of generic and essential medicines in the market. It can do so because India's large pharmaceutical industry is a major source of generic medicines worldwide. In this article, we discuss three factors that have impeded access to generic and essential medicines: (1) mistaken notions among policymakers, prescribers and patients about branded drugs and generic drugs in India; (2) high prices of medicines due to the progressive dismantling of the system of regulation of medicine prices, and (3) a drug approval and regulatory system that allows medicines (including fixed dose combinations) of doubtful efficacy, rationale, safety and public health relevance to dominate the market at the cost of access to affordable generic and essential medicines. The consequences of ill-health and wasted expenditure on drugs raise issues of public health ethics.Improving access to essential medicines in India is an urgent public health and ethical imperative. This should include improved public provisioning, a system of regulation of drug prices, and an evidence-based drug approval process. PMID:23697486

  1. The Water Risks of Hydraulic Fracturing (Fracking): Key Issues from the New California Assessment

    2015-12-01

    A key component of the Water-Energy Nexus is the effort over the past decade or so to quantify the volumes and form of water required for the energy fuel cycle from extraction to generation to waste disposal. The vast majority of the effort in this area has focused on the water needs of electricity generation, but other fuel-cycle components also entail significant water demands and threats to water quality. Recent work for the State of California (managed by the California Council on Science and Technology - CCST) has produced a new state-of-the-art assessment of a range of potential water risks associated with hydraulic fracturing and related oil and gas extraction, including volumetric water demands, methods of disposal of produced water, and aquifer contamination. For example, this assessment produced new information on the disposal of produced water in surface percolation pits and the potential for contamination of local groundwater (see Figure). Understanding these risks raises questions about current production and future plans to expand production, as well as tools used by state and federal agencies to manage these risks. This talk will summarize the science behind the CCST assessment and related policy recommendations for both water and energy managers.

  2. Key issues in estimating energy and greenhouse gas savings of biofuels: challenges and perspectives

    2016-06-01

    Full Text Available The increasing demand for biofuels has encouraged the researchers and policy makers worldwide to find sustainable biofuel production systems in accordance with the regional conditions and needs. The sustainability of a biofuel production system includes energy and greenhouse gas (GHG saving along with environmental and social acceptability. Life cycle assessment (LCA is an internationally recognized tool for determining the sustainability of biofuels. LCA includes goal and scope, life cycle inventory, life cycle impact assessment, and interpretation as major steps. LCA results vary significantly, if there are any variations in performing these steps. For instance, biofuel producing feedstocks have different environmental values that lead to different GHG emission savings and energy balances. Similarly, land-use and land-use changes may overestimate biofuel sustainability. This study aims to examine various biofuel production systems for their GHG savings and energy balances, relative to conventional fossil fuels with an ambition to address the challenges and to offer future directions for LCA based biofuel studies. Environmental and social acceptability of biofuel production is the key factor in developing biofuel support policies. Higher GHG emission saving and energy balance of biofuel can be achieved, if biomass yield is high, and ecologically sustainable biomass or non-food biomass is converted into biofuel and used efficiently.

    Full Text Available Abstract Background Health visitors play a pivotal position in providing parents with up-to-date evidence-based care on child health. The recent controversy over the safety of the MMR vaccine has drawn attention to the difficulties they face when new research which raises doubts about current guidelines and practices is published. In the aftermath of the MMR controversy, this paper investigates the sources health visitors use to find out about new research evidence on immunisation and examines barriers and facilitators to using evidence in practice. It also assesses health visitors' confidence in using research evidence. Methods Health visitors were recruited from the 2007 UK Community Practitioners' and Health Visitors' Association conference. All delegates were eligible to complete the questionnaire if in their current professional role they advise parents about childhood immunisation or administer vaccines to children. Of 228 who were eligible, 185 completed the survey (81.1%. Results These health visitors used a wide range of resources to find out about new research evidence on childhood immunisation. Popular sources included information leaflets and publications, training days, nursing journals and networking with colleagues. A lack of time was cited as the main barrier to searching for new evidence. The most common reason given for not using research in practice was a perception of conflicting research evidence. Understanding the evidence was a key facilitator. Health visitors expressed less confidence about searching and explaining research on childhood immunisation than evidence on weaning and a baby's sleep position. Conclusion Even motivated health visitors feel they lack the time and, in some cases, the skills to locate and appraise research evidence. This research suggests that of the provision of already-appraised research would help to keep busy health professionals informed, up-to-date and confident in responding to public

    Sierra Leone experienced intense transmission of Ebola virus disease (EVD) from May 2014 to November 2015 during which a total of 8,704 confirmed cases and over 3,589 confirmed deaths were reported. Our field observation showed many issues in the EVD data management system, which may have contributed to the magnitude and long duration of the outbreak. In this perspective article, we explain the key issues with EVD data management in the field, and the resulting obstacles in analyzing key epidemiological indicators during the outbreak response work. Our observation showed that, during the latter part of the EVD outbreak, surveillance and data management improved at all levels in the country as compared to the earlier stage. We identified incomplete filling and late arrival of the case investigation forms at data management centers, difficulties in detecting double entries and merging identified double entries in the database, and lack of clear process of how death of confirmed cases in holding, treatment, and community care centers are reported to the data centers as some of challenges to effective data management. Furthermore, there was no consolidated database that captured and linked all data sources in a structured way. We propose development of a new application tool easily adaptable to new occurrences, regular data harmonization meetings between national and district data management teams, and establishment of a data quality audit system to assure good quality data as ways to improve EVD data management during future outbreaks.

We identified incomplete filling and late arrival of the case investigation forms at data management centers, difficulties in detecting double entries and merging identified double entries in the database, and lack of clear process of how death of confirmed cases in holding, treatment, and community care centers are reported to the data centers as some of challenges to effective data management. Furthermore, there was no consolidated database that captured and linked all data sources in a structured way. We propose development of a new application tool easily adaptable to new occurrences, regular data harmonization meetings between national and district data management teams, and establishment of a data quality audit system to assure good quality data as ways to improve EVD data management during future outbreaks.

  9. Key Interface Issues in Spent Fuel Dry Storage and Transport in the U.S.A.. Annex XV

    International Nuclear Information System (INIS)

    Spent fuel management options in the U.S.A. have expanded significantly over the last 25 years as the dry storage of spent fuel has increased dramatically. After a period of 12 years or so (from the mid-1980s to the late-1990s) of moving spent fuel from wet storage into dry storage-only systems (licensed only for storage), the U.S.A. nuclear utility industry now places most of its dry-stored spent fuel into technologies that are certified by the U.S.A. Nuclear Regulatory Commission (NRC) for both spent fuel storage and transport, typically called multipurpose or dual purpose systems in the U.S.A. This places a significant focus at U.S.A. nuclear plants on planning for transitioning spent fuel from wet storage to dry storage, then, hopefully, from dry storage to dry transport. NAC has provided multipurpose canister system (MCS) technology for dry storage of spent fuel, as well as transportation services for spent fuel using its fleet of spent fuel transport casks, for many years. This experience has identified some very important, or key, spent fuel management interface issues, which all organizations planning to transition to dry spent fuel storage or to perform spent fuel transport might wish to review and consider. This paper and presentation offer brief highlights of these key interface issues

    This paper has studied the key issues about integration of GNSS and strong-motion records for real-time earthquake monitoring. The validations show that the consistence of the coordinate system must be considered firstly to exclude the system bias between GNSS and strong-motion. The GNSS sampling rate is suggested about 1-5 Hz, and we should give the strong-motion's baseline shift with a larger dynamic noise as its variation is very swift. The initialization time of solving the baseline shift is less than one minute, and ambiguity resolution strategy is not greatly improved the solution. The data quality is very important for the solution, we advised to use multi-frequency and multi-system observations. These ideas give an important guide for real-time earthquake monitoring and early warning by the tight integration of GNSS and strong-motion records.

    1995-08-01

    In recent years, Latin America`s hydrocarbons sector has been characterized by reorganization, revitalization, regional cooperation, environmental awakening, and steady expansion. The pattern of these changes, which appear to be the megatrends of the region`s hydrocarbons sector development, will continue during the rest of the 1990s. To further study the current situation and future prospects of Latin America`s hydrocarbons sector, we critically summarize in this short article the key issues in the region`s oil and gas development. These megatrends in Latin America`s hydrocarbons sector development will impact not only the future energy demand and supply in the region, but also global oil flows in the North American market and across the Pacific Ocean. Each country is individually discussed; pipelines to be constructed are discussed also.

  16. Experimental Study and Computational Simulations of Key Pebble Bed Thermo-mechanics Issues for Design and Safety

    2014-07-08

    An experimental and computational study, consisting of modeling and simulation (M&S), of key thermal-mechanical issues affecting the design and safety of pebble-bed (PB) reactors was conducted. The objective was to broaden understanding and experimentally validate thermal-mechanic phenomena of nuclear grade graphite, specifically, spheres in frictional contact as anticipated in the bed under reactor relevant pressures and temperatures. The contact generates graphite dust particulates that can subsequently be transported into the flowing gaseous coolent. Under postulated depressurization transients and with the potential for leaked fission products to be adsorbed onto graphite 'dust', there is the potential for fission products to escape from the primary volume. This is a design safety concern. Furthermore, earlier safety assessment identified the distinct possibility for the dispersed dust to combust in contact with air if sufficient conditions are met. Both of these phenomena were noted as important to design review and containing uncertainty to warrant study. The team designed and conducted two separate effects tests to study and benchmark the potential dust-generation rate, as well as study the conditions under which a dust explosion may occure in a standardized, instrumented explosion chamber.

  17. Development of safety-related regulatory requirements for nuclear power in developing countries. Key issue paper no. 4

    International Nuclear Information System (INIS)

    In implementing a national nuclear power program, balanced regulatory requirements are necessary to ensure nuclear safety and cost competitive nuclear power, and to help gain public acceptance. However, this is difficult due to the technology-intensive nature of the nuclear regulatory requirements, the need to reflect evolving technology and the need for cooperation among multidisciplinary technical groups. This paper suggests approaches to development of balanced nuclear regulatory requirements in developing countries related to nuclear power plant safety, radiation protection and radioactive waste management along with key technical regulatory issues. It does not deal with economic or market regulation of electric utilities using nuclear power. It suggests that national regulatory requirements be developed using IAEA safety recommendations as guidelines and safety requirements of the supplier country as a main reference after careful planning, manpower buildup and thorough study of international and supplier country's regulations. Regulation making is not recommended before experienced manpower has been accumulated. With an option that the supplier country's regulations may be used in the interim, the lack of complete national regulatory requirements should not deter introduction of nuclear power in developing countries.

    Understanding how to source agricultural raw materials sustainably is challenging in today's globalized food system given the variety of issues to be considered and the multitude of suggested indicators for representing these issues. Furthermore, stakeholders in the global food system both impact these issues and are themselves vulnerable to these issues, an important duality that is often implied but not explicitly described. The attention given to these issues and conceptual frameworks varies greatly--depending largely on the stakeholder perspective--as does the set of indicators developed to measure them. To better structure these complex relationships and assess any gaps, we collate a comprehensive list of sustainability issues and a database of sustainability indicators to represent them. To assure a breadth of inclusion, the issues are pulled from the following three perspectives: major global sustainability assessments, sustainability communications from global food companies, and conceptual frameworks of sustainable livelihoods from academic publications. These terms are integrated across perspectives using a common vocabulary, classified by their relevance to impacts and vulnerabilities, and categorized into groups by economic, environmental, physical, human, social, and political characteristics. These issues are then associated with over 2,000 sustainability indicators gathered from existing sources. A gap analysis is then performed to determine if particular issues and issue groups are over or underrepresented. This process results in 44 "integrated" issues--24 impact issues and 36 vulnerability issues--that are composed of 318 "component" issues. The gap analysis shows that although every integrated issue is mentioned at least 40% of the time across perspectives, no issue is mentioned more than 70% of the time. A few issues infrequently mentioned across perspectives also have relatively few indicators available to fully represent them. Issues in the

    Full Text Available [english] These days family-friendliness is a key issue for the future of businesses. Investments in a family conscious personnel policy are considered as forward-looking decisions in companies. This happens against the background of a sustainable personnel policy in times of a decrease in the number of employable persons, an increasing shortage of skilled workers and an ageing workforce. Family-friendly working conditions are becoming a key factor in the competition for staff. When choosing an employer, family-friendliness has become a crucial topic. Employment participation and skills of women, especially of mothers, have greatly increased. To facilitate the realisation of their wish to return to paid employment, however, measures to reconcile work and family are required.Family-conscious measures have been proven to lead to higher employee productivity. Job satisfaction and motivation of employees and accumulation of human capital increase, absenteeism declines, the return of investment rises. Fields of activity for family-friendly measures in companies range from working arrangements, parental leave and re-entry programmes and various child care offers to services for families. In connection with the demographic development the demand for a better reconciliation of work and elder care should in future become ever more important, just as the upkeep of the occupational skills and working capacity of an ageing workforce. Family-friendliness has to become an integral part of corporate culture.

  1. Using Eight Key Questions as an Inquiry-Based Framework for Ethical Reasoning Issues in a General Education Earth Systems and Climate Change Course

    Science.gov (United States)

    Johnson, E. A.; Ball, T. C.

    2014-12-01

    An important objective in general education geoscience courses is to help students evaluate social and ethical issues based upon scientific knowledge. It can be difficult for instructors trained in the physical sciences to design effective ways of including ethical issues in large lecture courses where whole-class discussions are not practical. The Quality Enhancement Plan for James Madison University, "The Madison Collaborative: Ethical Reasoning in Action," (http://www.jmu.edu/mc/index.shtml) has identified eight key questions to be used as a framework for developing ethical reasoning exercises and evaluating student learning. These eight questions are represented by the acronym FOR CLEAR and are represented by the concepts of Fairness, Outcomes, Responsibilities, Character, Liberty, Empathy, Authority, and Rights. In this study, we use the eight key questions as an inquiry-based framework for addressing ethical issues in a 100-student general education Earth systems and climate change course. Ethical reasoning exercises are presented throughout the course and range from questions of personal behavior to issues regarding potential future generations and global natural resources. In the first few exercises, key questions are identified for the students and calibrated responses are provided as examples. By the end of the semester, students are expected to identify key questions themselves and justify their own ethical and scientific reasoning. Evaluation rubrics are customized to this scaffolding approach to the exercises. Student feedback and course data will be presented to encourage discussion of this and other approaches to explicitly incorporating ethical reasoning in general education geoscience courses.

    Despite a severe regulation concerning the building in flooding areas, 80% of these areas are already built in the Greater Paris (Paris, Val-de-Marne, Hauts-de-Seine and Seine-Saint-Denis). The land use in flooding area is presented as one of the main solutions to solve the ongoing real estate pressure. For instance some of the industrial wastelands located along the river are currently in redevelopment and residential buildings are planned. So landuse in the flooding areas is currently a key issue in the development of the Greater Paris area. Tools and measures, structural or non-structural such as warning systems, barriers, etc do exist and could be a smart way to improve the resilience of the new urbanised areas. The technical solutions are available and efficient, but we notice that these tools are not much implemented. There is a lack of flood risk concern among the stakeholders and the inhabitants1. How landuse stakeholders could integrate the flood risk in the decision making process throughout the implementation of the urban project? Which type of governance favours an efficient development of good flood risk policy including prevention, protection and the management of the crisis? What is the "good" governance of the urban project e.g. enabling to take into account or not to forget the flood risk and to empower the (future) inhabitants? This inhabitants' empowerment includes the improvement of awareness (i.e. inhabitants being aware that they live in a flooded area) and the improvement of concern (i.e. inhabitants adopting the "right" behaviour when the risk occurs). In order to investigate how flood risk is or could be integrated in the project governance, we interviewed stakeholders (elected representatives, architects, property developers, etc.) and observed the integration or the vanishing of the risk throughout the project. In order to develop this topic we rely on a case study. The "Ardoines" is a project aiming at redeveloping an industrial site

    Although science and engineering (S&E) publications and doctoral degree awards in Latin America had experienced an impressive growth in the past decades, a qualitative evaluation of this increased output must be performed. Previous studies have indicated that growth in visibility of Latin American science - determined by ratio of citations per paper - has not kept pace with the increase in number of publications. In the present editorial, we analyzed - by means of a 12-item questionnaire - the individual perceptions of forty senior researchers involved in CBP-Latin America (29 Brazilians and 11 non-Brazilians) plus a special group composed by six extraordinary Latin American scientists (the "masters"). The questionnaire - using 6-point Likert-like scale for quantification of perception - focused on issues surrounding doctoral educational system as well as the governmental educational policies and publication pressure from funding agencies. In general, the most striking result was the perception (by 82% of respondents) of lack of job opportunities for people holding a PhD diploma in the field of comparative biochemistry and physiology. Other major trends include (i) lack of satisfaction with governmental policies for science and post-graduate education due to policies promoting mass production for papers and PhD diplomas (65-77% of respondents felt that way) (ii) that current PhD students are doing an adequate job, but have not improved in quality as compared to those from 10 years ago (the same was observed for PhD thesis in terms of present versus past), and (iii) that research infrastructure and the curricula of post-graduate courses do not constitute a problem, but (iv) recent-PhDs are not as fit as they should be in paper-writing skills, especially as perceived by Brazilian respondents. The general perceptions were very similar among Brazilians, non-Brazilians and "masters". The use of a larger study-population, with scientists of more diverse fields is the

    Foutakis Dimitris

    2009-01-01

    Full Text Available Two years after the inception of the fourth programming period, the debate on post-2013 cohesion policy has already been launched. In fact, public consultation was launched in 2007 and considerable steps have followed since then, while others are about to start. At the same time, the new strategic guidelines and rules that guide cohesion policy have only been in place for a short period and as yet their impacts are not clear. Critical events and major political issues that concern the whole EU structure are the main factors behind this evolution. In particular, the economic recession in addition to the prospects for the new EU Treaty could be considered decisive elements in the launch of the debate on future cohesion policy. More specifically, among the issues highlighted in this context are the distinction between efficiency and equity objectives, the need for a place-based strategy, high growth sectors and their contribution to cohesion, and the potential for creativity and innovation. Overall, it seems like old dilemmas of spatial development recur, while contemporary ones also gain ground. The outcome of this debate is of significant importance for all EU regions not only in budgetary terms, but also in terms of strategic policy goals. This paper examines the above future policy issues with an emphasis on regions faced with particular difficulties such as less favored regions as well as those in the EU periphery.

  11. Key practical issues in strengthening safety culture. INSAG-15. A report by the International Safety Advisory Group

    International Nuclear Information System (INIS)

    This report describes the essential practical issues to be considered by organizations aiming to strengthen safety culture. It is intended for senior executives, managers and first line supervisors in operating organizations. Although safety culture cannot be directly regulated, it is important that members of regulatory bodies understand how their actions affect the development of attempts to strengthen safety culture and are sympathetic to the need to improve the less formal human related aspects of safety. The report is therefore of relevance to regulators, although not intended primarily for them. The International Nuclear Safety Advisory Group (INSAG) introduced the concept of safety culture in its INSAG-4 report in 1991. Since then, many papers have been written on safety culture, as it relates to organizations and individuals, its improvement and its underpinning prerequisites. Variations in national cultures mean that what constitutes a good approach to enhancing safety culture in one country may not be the best approach in another. However, INSAG seeks to provide pragmatic and practical advice of wide applicability in the principles and issues presented in this report. Nuclear and radiological safety are the prime concerns of this report, but the topics discussed are so general that successful application of the principles should lead to improvements in other important areas, such as industrial safety, environmental performance and, in some respects, wider business performance. This is because many of the attitudes and practices necessary to achieve good performance in nuclear safety, including visible commitment by management, openness, care and thoroughness in completing tasks, good communication and clarity in recognizing major issues and dealing with them as a priority, have wide applicability

  12. Examination of Ethnic and Policy Issues in Grooming Preferences and Ethnic Hairstyles of African American Women in Corporate America

    Directory of Open Access Journals (Sweden)

    Angela Renee Payne

    2011-12-01

    Full Text Available For a century, college-trained, professional racial minorities: specifically, African American women with a preference in grooming methods have contributed to the labor market; however, in the new millennium, they are often discriminated against, scoffed at, isolated, and demoralized based on ethnic hairstyles. Research studies have distinguished a depth of research on this and conversely there are limited studies on racial minorities, in particular among grooming preferences in ethnic hairstyles. Studies have shown that in progressive companies, racial minorities and African American women who wear ethnic hairstyles had their employment terminated with prejudice. With regard to these case studies and findings, one could argue that in this nation there is freedom of speech and inequality in expression. For this reason, this research is very necessary to discover variables in ethnic and policy issues in grooming preferences with regard to the ethnic hairstyles of African American women as it relates to employers, whereat cohesive practices in diversity and policies address imposing construct in the labor market. This research will not address every ethnical concern in the labor market; yet, it responds to a call in the literature to define managerial deficiencies against racial minorities: in particular, African American women in grooming preferences.

  13. Environmental impacts and issues of In-Situ Leach uranium mining in the United States of America

    International Nuclear Information System (INIS)

    Full text: In-situ leach (ISL) mining of sandstone-hosted deposits has been steadily producing uranium in the U.S. since the late 1970s. In Texas, 38 mines have extracted uranium along the southwest Texas coastal plain. Wyoming production has come from three mines developed in the Powder River Basin, and Nebraska has one active ISL facility in the Crawford Basin. Twenty new or expanded ISL mines are expected to submit license applications within the next two years. Increasing concern over groundwater degradation resulting from uranium ISL mining has resulted in more extensive state regulation and prompted the U.S. Geological Survey to review restoration data for these mines to quantify environmental impacts and critical issues. ISL mines in the United States inject oxygen or hydrogen peroxide enriched ground water into reduced roll-front deposits to extract uranium via carbonate-uranyl complexes in ground water. Some operators add carbon dioxide, carbonate or bicarbonate to the lixiviant as a carrying agent, although sandstones in the U.S. commonly contain enough native carbonate that this is unnecessary. Other lixiviants utilized in past operations including sodium and ammonium bicarbonate and sulphuric acid are not used in modern U.S. operations because of difficulties in restoring ground water to pre-mining conditions. Baseline studies show Ra, U, As, Pb, Cd, Se, and Hg in groundwater before ISL mining are typically elevated above U.S. Environmental Protection Agency (EPA) drinking water Maximum Contaminant Levels (MCL). Cl, Mn, Fe, total dissolved solids, and sulfate are commonly elevated above secondary EPA standards. Newly-raised challenges to ISL mining have questioned the validity of statistical methods used when calculating baseline values in ISL operations. Restoration techniques used in U.S. ISL well fields are dominated by ground water sweep and treatment of ground water by reverse osmosis. Additionally, two well fields have been restored using

  14. A Policy Analysis and Quantitative Assessment of Key Issues Arising from Climate Change Negotiations Following COP 7

    International Nuclear Information System (INIS)

    This paper aims to assess the consequences of the amendments made to the Kyoto Protocol during COP 7 in Marrakech. Following a comprehensive policy analysis, the major issue of 'hot air' and CDM transaction costs is examined using the CERT model. This was done to show that primary supply regions, typically those with 'hot air' availability, might control the emissions reduction permit supply market and maximise net export revenues of permit supply by withholding 40 to 60% of available 'hot air' credits. The assumption that primary permit suppliers control permit price via a restriction of 'hot air' supply to the market will inadvertently leave a portion of the market share open to Non-Annex B CDM supply, despite potentially extreme variance in CDM transaction costs. A summary table of policy implications on the emissions reduction permit market is also included in the Appendix. (author)

    Ambient heat exposure is a well-known health hazard, which reduces human performance and work capacity at heat levels already common in tropical and subtropical areas. Various health problems have been reported. Increasing heat exposure during the hottest seasons of each year is a key feature of global climate change. Heat exhaustion and reduced human performance are often overlooked in climate change health impact analysis. Later this century, many among the four billion people who live in hot areas worldwide will experience significantly reduced work capacity owing to climate change. In some areas, 30-40% of annual daylight hours will become too hot for work to be carried out. The social and economic impacts will be considerable, with global gross domestic product (GDP) losses greater than 20% by 2100. The analysis to date is piecemeal. More analysis of climate change-related occupational health impact assessments is greatly needed.

  18. Hydrodynamics of coalbed methane reservoirs in the Black Warrior Basin: Key to understanding reservoir performance and environmental issues

    International Nuclear Information System (INIS)

    The Black Warrior Basin of the southeastern United States hosts one of the world's most prolific and long-lived coalbed methane plays, and the wealth of experience in this basin provides insight into the relationships among basin hydrology, production performance, and environmental issues. Along the southeast margin of the basin, meteoric recharge of reservoir coal beds exposed in an upturned fold limb exerts a strong control on water chemistry, reservoir pressure, and production performance. Fresh-water plumes containing Na-HCO3 waters with low TDS content extend from the structurally upturned basin margin into the interior of the basin. Northwest of the plumes, coal beds contain Na-Cl waters with moderate to high-TDS content. Carbon isotope data from produced gas and mineral cements suggest that the fresh-water plumes have been the site of significant bacterial activity and that the coalbed methane reservoirs contain a mixture of thermogenic and late-stage biogenic gases. Water produced from the fresh-water plumes may be disposed safely at the surface, whereas underground injection has been used locally to dispose of highly saline water. Wells in areas that had normal hydrostatic reservoir pressure prior to development tend to produce large volumes of water and may take up to 4 a to reach peak gas production. In contrast, wells drilled in naturally underpressured areas distal to the fresh-water plumes typically produce little water and achieve peak gas rates during the first year of production. Environmental debate has focused largely on issues associated with hydrologic communication between deep reservoir coal beds and shallow aquifers. In the coalbed methane fields of the Black Warrior Basin, a broad range of geologic evidence suggests that flow is effectively confined within coal and that the thick intervals of marine shale separating coal zones limit cross-formational flow

    Understanding how large-scale bioenergy production can affect biodiversity and ecosystems is important if society is to meet current and future sustainable development goals. A variety of bioenergy production systems have been established within different contexts throughout the Pan American region, with wide-ranging results in terms of documented and projected effects on biodiversity and ecosystems. The Pan American region is home to the majority of commercial bioenergy production and therefore the region offers a broad set of experiences and insights on both conflicts and opportunities for biodiversity and bioenergy. This paper synthesizes lessons learned focusing on experiences in Canada, the United States, and Brazil, regarding the conflicts that can arise between bioenergy production and ecological conservation, and benefits that can be derived when bioenergy policies promote planning and more sustainable land management systems. We propose a research agenda to address priority information gaps that are relevant to biodiversity concerns and related policy challenges in the Pan American region.

  11. Non-Darcian flow in low-permeability media: key issues related to geological disposal of high-level nuclear waste in shale formations

    Science.gov (United States)

    Liu, Hui-Hai

    2014-05-01

    In clay or other low-permeability media, water flow becomes non-Darcian and characterized by the non-linear relationship between water flux and hydraulic gradient. This work is devoted to addressing a number of key issues related to geological disposal of high-level nuclear waste in clay/shale formations. It is demonstrated that water flow velocity in the damaged zone (often considered as a potential preferential advection paths in a repository) surrounding the tunnel is extremely small, as a result of non-Darcian flow behavior, such that solute transport is dominated by diffusion, rather than advection. The finding is also consistent with the often-observed existence of persistent abnormal pressures in shale formations. While relative permeability is the key parameter for modeling the unsaturated flow process, without incorporating non-Darcian flow behavior, significant errors can occur in the determination of relative permeability values from traditional measurement methods. An approach for dealing with temperature impact on non-Darcian flow and a formulation to calculate non-Darcian water flux in an anisotropic medium are presented, taking into consideration that a geological repository is subject to temperature evolution in the near field as a result of heat generated by nuclear waste, and that shale formations are generally anisotropic.

  13. Natural gas in Latin America

    International Nuclear Information System (INIS)

    Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

    2005-09-01

    As it has been beautifully demonstrated in synchrotron facilities, water window transmission x-ray microscopy (WW-TXM) has a great potential for high resolution three dimensional (3D) tomographic imaging of frozen cells, without the cumbersome staining and slicing preparation needed by electron microscopy. However, the existing instruments do not exactly meet the expectations of cell biologists in terms of performance and accessibility: 3D images of entire cells grown on a flat substrate with details in the 50-80nm range are necessary for structural cell studies. Functional imaging is also a key issue. Specific molecular probes are widely used to achieve molecular imaging in optical and electron microscopy. The same demand applies to x-ray microscopy. Immediate availability of the observation technique within the biology laboratory is as important as its performance. Therefore, WW-TXM will develop on a wider scale only when table-top instruments become available. We present a detailed analysis of such a microscope. The source is clearly the key element. Laser created plasmas of carbon or nitrogen are a proven but expensive solution. Cerenkov emission in vanadium has been demonstrated as a potential monochromatic source, but we emphasize severe obstacles: huge thermal load and radiation protection. We show that oxygenKα line excitation by an electron beam is a realistic alternative. Being a purely monochromatic source, it would allow the use of a high efficiency mirror condenser, while laser plasmas imply spectral selection with the associated losses. We then describe the main elements of an affordable laboratory microscope, supported by numerical simulations and preliminary experimental work. We also show that functionalized quantum dots, currently used in fluorescence microscopy, are equally detectable with soft x-rays and would allow a dual modality observation. Finally, the expected performance of this prototype is discussed and confronted by the requirements

As the first mandatory legal document for reduction of gas emissions at international level that applies both to developed and developing countries, the above amendment does not adopt the principle of common but differentiated responsibilities and will accordingly have important impact on both international negotiations on the change of climate and the shipbuilding and shipping industry. China is a developing country as well as a big shipping state; it will surely face more pressure on the issue of reduction of greenhouse gas emissions after the approval of the above amendment. It is suggested that the key issues during the relevant negotiation process should be further probed and well handled.

    investigation of phenological cycle. The methodology of plant phenology has been upgraded from the superficial description on the response of plant phenological cycle to climate change to the coupling exploration on plant phenology at the multi-scale and multi-element scales. With the development of interdisciplinary research, plant phenology has been extended to a systematic evaluation on the impacts of phenological changes on ecosystems , climatic change , agricultural production and even human health. With these transitions , a few key issues has been raised accordingly, such as the differentiate contribution of atmospheric temperature and photoperiod to plant phenological cycle in different temperature belts , the nonlinear characteristics of the change in plant phenology versus climate change , the complexity of plant phenology at the community level, as well as the importance of crop phenology in agricultural ecosystems. It can be argued that the initiative of plant phenology would play a critical role in practical fields such as agricultural production, human health and landscape design, but also significantly boosts the progress in interdisciplinary research involved in ecology, climatology and geography.

    Full Text Available The issue of modernity has held a central place in Latin America's history and, for that reason, it has been the object of numerous reflections from a wide variety of disciplines and theoretical perspectives. However, most of these reflections have maintained a canonical definition of modernity, which conceives it as a linear and accumulative rationalization process. This vision has had important implications for Latin American societies. Thus, a critical revision of the very idea of modernity and the ways in which it has been perceived in Latin America could result in new keys for interpreting the historical trajectories of our societies.

  15. Preparing tomorrow's network today: RTE at the crossroads of the European electricity system. Cross-border electricity interconnections Key issues and figures - 2014 Edition

    International Nuclear Information System (INIS)

    The interconnected electricity transmission network is a key element for ensuring security of supply, the creation of a single market and the integration of renewable energies. RTE and its European partners provide strengthened coordination by the use of interconnections to ensure solidarity between European countries. Interconnections also allow an electricity supplier to sell its energy to a customer located in another country in Europe. They contribute on a European scale to optimising the use of production means and in particular the integration of variable renewable energies. RTE, within the EnTSo-E (European Network of Transmission System Operators for Electricity), contributes to the publication of a common vision of the future of networks by 2030. The needs for new interconnection capacity are identified in the ten-year European network development plan (TYnDP) on the basis of a cost-benefit analysis. France is interconnected to all its neighbours via many cross-border links. However interconnection capacity with the various countries and its use differ widely. The usage profile of the interconnections is specific to each border and varies according to: - the characteristics of the production mix of each country, and in particular the level of production of renewable energies. - the level of consumption, which depends on the season, the type of day (working or non-working) the time of day, etc. - import and export capacity, which may be different depending on the internal constraints of the networks of each country

    Due to its high specific energy content, liquid hydrogen (LH2) is emerging as an alternative fuel for future aircraft. As a result, there is a need for hydrogen tank storage systems, for these aircraft applications, that are expected to provide sufficient capacity for flight durations ranging from a few minutes to several days. It is understood that the development of a large, lightweight, reusable cryogenic liquid storage tank is crucial to meet the goals of and supply power to hydrogen-fueled aircraft, especially for long flight durations. This report provides an annotated review (including the results of an extensive literature review) of the current state of the art of cryogenic tank materials, structural designs, and insulation systems along with the identification of key challenges with the intent of developing a lightweight and long-term storage system for LH2. The broad classes of insulation systems reviewed include foams (including advanced aerogels) and multilayer insulation (MLI) systems with vacuum. The MLI systems show promise for long-term applications. Structural configurations evaluated include single- and double-wall constructions, including sandwich construction. Potential wall material candidates are monolithic metals as well as polymer matrix composites and discontinuously reinforced metal matrix composites. For short-duration flight applications, simple tank designs may suffice. Alternatively, for longer duration flight applications, a double-wall construction with a vacuum-based insulation system appears to be the most optimum design. The current trends in liner material development are reviewed in the case that a liner is required to minimize or eliminate the loss of hydrogen fuel through permeation.

    This document reports on BIOPROTA Theme 2, task 7 which investigated modelling processes in the geosphere- biosphere interface zone (GBIZ) during performance assessments. Modelling issues in the treatment of the GBIZ are identified. A large proportion of the identified issues concern modelling radionuclide behaviour in near surface aquifers which are subject to relatively high gradients in chemical and other conditions. Other key issues concern transfer of radionuclides through the unsaturated zone above aquifers, bearing in mind the scope for erosion and variations in the level of the phreatic surface and also the consideration of environmental change. A number of research areas are highlighted that are aimed at addressing each of the identified issues in the treatment of GBIZ. These include (i) Developing of a current statement of continuing problems, and hence clarify and justify the need to do more; (ii) Conducting a review of site investigations as they have been done already, and determine whether they meet performance assessment requirements; (iii) Identifying scenarios and FEPs considered in current treatments; and, (iv) Conducting source-pathway-receptor analysis to demonstrate comprehensiveness of the overall scenario identification process. The objectives of these activities would be to determine the potential to reduce uncertainties and/or conservative assumptions in assessment of radionuclide transfer from the geosphere to biosphere domains, taking account of environmental change; and to develop guidance on site-characterisation needs at different types of site, as regards the near-surface features.

    develop new stratedgies for China national DNA database? How to further develop China DNA database and maximize its efficiency? This paper discusses the development in the light of 4 issues. First of all, the core loci of database need to be set prior to increasing the number of autosomal STR loci, even though there is a consensus on the quantity change. As for the new genetic markers, such as SNP, the attitude of “good will of expectation” should be in line with “prudent wait-and-see”, since there is few possibility to use SNP commonly in a database with ten-million profiles. It is more likely that the genome-wide analysis will bring the great change to the DNA database in the future. Still, the special familial searching is a supplementation and inevitable choice for DNA database in case of a low coverage of the population. But this searching has to follow strict rule. Finally, Y-STR database development is objective and urgent, but it must be cautious as personnel sample collection might be involving legal, social and other problems; the pedigree in sociological term may not equal to genetic one; positive evaluations of Y-STR database should be also built on deductive method; a balanced development of database should be considered of both costs and benefits. Therefore, without a theoretical framework constructed with rigorous deduction, especially prior to the mathematical model of evaluation, Y-STR database is only a matter of empirical, rather than scientific, letting alone the difficulty to assess the value of such experience for others. In conclusion, as a DNA database with ten-millions profiles, any change related to fundamental issues concerned with development, security or stability must be dealt with comprehensively and scientifically.

  1. Biomass energy in Central America

    International Nuclear Information System (INIS)

    The objective of this paper is to introduce the concept of biomass to energy issues and opportunities in Central America. In this region, made up of seven countries (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama), the biomass sector has the potential to play a crucial role in alleviating the environmental and development predicaments faced by all economies of the region. This paper assesses the available biomass resources at the regional and country levels and gives an overview of the current utilization of biomass fuels. It also describes the overall context in which the biomass-to-energy initiatives are immersed. At the regional level, biomass energy consumption accounts for more than 50% of total energy consumption. In regard to the utilization of biomass for energy purposes, it is clear that Central America faces a critical juncture at two levels, both mainly in rural areas: in the productive sector and at the household level. The absence of sustainable development policies and practices has jeopardized the availability of biomass fuels, particularly wood. Firewood is an important source of energy for rural industries such as coffee processing, which is one of the largest productive activities in the region. This paper comments on some of the most successful technological innovations already in place in the region, for instance, the rapid development of co-generation projects by the sugar cane industry, especially in El Salvador and Guatemala, the substitution of coffee husks for firewood in coffee processing plants in Costa Rica and El Salvador and the sustainable use of pine forests for co-generation in Honduras. Only one out of every two inhabitants in Central America now has access to electricity from the public grid. Biomass fuels, mainly firewood but also, to a lesser extent, other crop residues such as corn stalks, are the main source of energy for cooking and heating by most of the population. (It is foreseen that by the end

    2013-08-01

    Sexual violence is known to be highly prevalent, albeit the majority of incidents are not reported to the authorities. It is therefore likely that medical students will encounter very many patients who have experienced sexual violence during their postgraduate careers, although this history may never be disclosed to them. Numerous highly regarded sources have advocated for the inclusion of instruction on the care of the victim of sexual violence in undergraduate medical curricula. Moreover, there has been a call for research to measure the effectiveness of educational strategies addressing the issue of sexual violence at undergraduate level. We present an evaluation of the effectiveness of a reproducible teaching session on care of the victim of sexual violence appropriate for undergraduate medical students, looking specifically at alterations in students' awareness of the key issues involved in patient care and their attitudes to such patients. This research demonstrates that such an educational intervention significantly enhances undergraduate medical students' awareness of the issues involved in patient care and their insight in to myths surrounding sexual violence.

    Sexual violence is known to be highly prevalent, albeit the majority of incidents are not reported to the authorities. It is therefore likely that medical students will encounter very many patients who have experienced sexual violence during their postgraduate careers, although this history may never be disclosed to them. Numerous highly regarded sources have advocated for the inclusion of instruction on the care of the victim of sexual violence in undergraduate medical curricula. Moreover, there has been a call for research to measure the effectiveness of educational strategies addressing the issue of sexual violence at undergraduate level. We present an evaluation of the effectiveness of a reproducible teaching session on care of the victim of sexual violence appropriate for undergraduate medical students, looking specifically at alterations in students' awareness of the key issues involved in patient care and their attitudes to such patients. This research demonstrates that such an educational intervention significantly enhances undergraduate medical students' awareness of the issues involved in patient care and their insight in to myths surrounding sexual violence.

  12. Key issues in european reactor seismic design

    International Nuclear Information System (INIS)

    The paper focuses on the main problems which have arisen in FBR design in Europe due to seismic conditions. Its first part, derived from the final report of a CEC-Belgonucleaire study contract, clarifies how ''real'' is the seismic problem for each site. Then, the second and main part deals with the studies carried out in the european countries on the relevant subjects, typical of FBRs or related to specific needs of single FBRs: these studies, for which contributions were provided by ENEA, CEA, NNC and INTERATOM, concern mainly the numerical and experimental analysis of the core, the reactor vessel, the shut-down system and the reactor building of FBRs under construction or in advanced design phase. Attention is also paid to the studies started for future purposes, the feed-backs on the design due to seismic conditions, and the instructions for future reactors

  14. COMPETITIVENESS - KEY ISSUES OF THE ROMANIAN ECONOMY

    Directory of Open Access Journals (Sweden)

    Gabriela-Liliana, CIOBAN

    2014-11-01

    Full Text Available Based on the theory that competitiveness plays an increasingly powerful role in creating prosperity, wealth, a large number of economists, researchers, scientists, highlight a number of approaches aimed, on the one hand, on the analysis of competitiveness at national or regional level, and on the other hand, on the ability of local firms to achieve competitive products and to commercialize them in the extern markets. In this context we aim to analyze and develop strategies and methods to help identify competitive areas at a national level. This is necessary because in our opinion the competitiveness of a company and / or country is more than wealth itself; it means a systematic process of wealth creation, plus a social system in which most citizens have access to material wealth. We consider in this respect that a country cannot automatically be considered competitive only if it is rich in natural resources. In our view, a competitive country creates wealth through labor, talent and organization and thus it manages to have a productive and creative potential making it independent of material resources.

  15. Key issues considered at LNG 13

    International Nuclear Information System (INIS)

    In the past few years, deregulation of the gas markets throughout the world has changed the way LNG projects can be brought into realisation. Gone are the days when large consortia of buyers could aggregate demand into quantities that made an LNG project economic. Today's market is typified by buyers requesting greater flexibility in volumes, shorter contract terms and reduced exposure to take-or-pay clauses. This means that the onus is on the producer to aggregate volume to make a large project viable, and to find flexible supply options as demand increases. As a result, there is an increasing ability to source LNG from excess capacity around the world, as has been demonstrated with the extended shutdown of the Arun LNG plant in Indonesia. Although some flexibility exists for the supply of LNG, it is unlikely that a world market where LNG is freely traded will develop. LNG projects will still require long-term contracts to ensure project financing. Furthermore, the 'LNG world' will remain separated into two regions the Atlantic and Asia-Pacific basins with only small amounts of 'spot' trading occurring between them. This is primarily due to the increased shipping costs associated with the global movement of LNG, and thus the ability to compete with closer sources of LNG and pipeline gas. Australia's position and its challenges in the LNG market is analysed

The seminar was followed by a celebratory lunch at the House of Lords, where the keynote speaker was Royal Academy of Engineering CEO, Philip Greenish (see HEJ--January 2016).

  1. Public information. Key issue paper no. 5

    International Nuclear Information System (INIS)

    Nuclear power was welcomed from the outset because it promised highly economic and convenient energy, especially electricity. Even today, nuclear projects espoused by developing nations can stimulate enthusiasm and national pride. However, public unease concerning nuclear power safety was magnified by the accidents at Three Mile Island in 1979 and Chernobyl in 1986. The perceived problem of transport and long term storage of nuclear waste has added to public concerns, as has the risk of the possible proliferation of nuclear weapons. Public information strategies must recognize and seek to address these fears by pointing to the many cumulative years of trouble-free nuclear operations and by stressing the strict rules and oversight designed to protect workers and the public from accidents and radioactive releases. It is against this background that the following material has been compiled. It comes from a variety of sources and reflects the experience mainly of industrialized countries that have national nuclear programs. It is important to underline that it is descriptive rather than prescriptive in nature for two reasons: first, the IAEA is essentially a forum for pooling collective knowledge in this as in other fields; and secondly, the IAEA would not presume to offer a universal formula, since national circumstances vary according to specific political, demographic, social and other factors. Hence only certain parts of this paper may be of direct relevance to any given national situation. (author)

    Macinko, James; Montenegro, Hernán; Nebot Adell, Carme; Etienne, Carissa

    2007-01-01

    At the 2003 meeting of the Directing Council of the Pan American Health Organization (PAHO), the PAHO Member States issued a mandate to strengthen primary health care (Resolution CD44. R6). The mandate led in 2005 to the document "Renewing Primary Health Care in the Americas. A Position Paper of the Pan American Health Organization/WHO [World Health Organization]," and it culminated in the Declaration of Montevideo, an agreement among the governments of the Region of the Americas to renew their commitment to primary health care (PHC). Scientific data have shown that PHC, regarded as the basis of all the health systems in the Region, is a key component of effective health systems and can be adapted to the range of diverse social, cultural, and economic conditions that exist. The new, global health paradigm has given rise to changes in the population's health care needs. Health services and systems must adapt to address these changes. Building on the legacy of the International Conference on Primary Health Care, held in 1978 in Alma-Ata (Kazakhstan, Union of Soviet Socialist Republics), PAHO proposes a group of strategies critical to adopting PHC-based health care systems based on the principles of equity, solidarity, and the right to the highest possible standard of health. The main objective of the strategies is to develop and/or strengthen PHC-based health systems in the entire Region of the Americas. A substantial effort will be required on the part of health professionals, citizens, governments, associations, and agencies. This document explains the strategies that must be employed at the national, subregional, Regional, and global levels.

  5. Latin America`s emerging non-proliferation consensus

    Latin America`s incorporation into the international nuclear non-proliferation regime is well advanced. The 1967 Tlatelolco Treaty, which established a regional nuclear-weapon-free zone (NWFZ), is nearing completion. A signal event occurred January 18, when Argentina and Chile deposited instruments of ratification to the treaty, leaving Brazil and Cuba the only major countries in Latin America that are not yet contracting parties. And after more than two decades of concern about the nuclear programs and policies in Argentina and Brazil, there is room for great optimism that Brazil may now be moving quickly on important non-proliferation issues. Even Cuba, the {open_quotes}bad boy of the neighborhood{close_quotes} in the eyes of many, which held aloof from the Tlatelolco process for three decades, has stated its willingness to join the zone in the future.

    Energy Technology Data Exchange (ETDEWEB)

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

    In high-income countries, social inequalities in cardiovascular disease (CVD) risk are well-documented. Although Latin America has a rich history of theory and conceptual discussion regarding social inequalities in health, empirical research has been more limited. In this commentary we summarize recent empirical work on social inequalities in CVD risk in Latin America, and highlight key research needs as well as implications for prevention. Although much remains unknown about the social patterning of CVD in Latin America, the limited studies to date indicate that inequalities in CVD risk vary across populations and markers of socioeconomic position, as well as disease risk marker. The strongest social inequalities are seen among women, and in urban areas, with regards to obesity, diabetes, and diet. Few studies, though, have been conducted in some parts of Latin America, including the countries of Central America and northern South America. Vital registration systems and nationally-representative risk factor surveys can be important sources of data, as long as information on socioeconomic indicators is collected. Longitudinal studies will also be important for investigating factors driving social inequalities. As policies and prevention strategies are put into place to reduce CVD in Latin America, they must also address factors generating social inequalities in CVD risk.

    The Chinese State Council has issued a series of policy documents to cool the real estate market, but the effect was quite limited. The latest measures include using administration order to restrict home purchase. The primary reason for the failure of controlling the real estate market is the government' s dependence on land for public finance. Real estate industries consume large quantities of land, steel, aluminum, cement, ceramic products and many other resources. When housing has become speculative or luxurious goods rather than necessities,, real estate is nothing but "three high industries" (high energy consumption, high waste discharge and high pollution). The key to achieve sustainable development goals is to reduce the local governments' dependence on land for finance. Switching to property tax is an important step. However, current pilot programs have many pitfalls and are blunt tools to correct existing problems.%中央接二连三发文调控房地产市场,但均无果而终.最后不得动用行政手段:限购令.但这种用行政手段干预市场的办法只能是应急的措施.房地产市场失控,根本在于地方政府对土地财政的依赖,这个关键问题没有解决,不仅房地产市场难步入正轨,中国的绿色发展也难行.房地产业耗用大量土地,消耗钢材、铝材、水泥、陶瓷…….一旦房地产业背离了民生的本质,成为投资标的物与奢侈品,住房标准严重脱离国情,非理性的住房消费,房地产业则蜕变为高耗能、高排放、高污染的“三高”产业.唯使地方政府摆脱土地财政的依赖,才抓住绿色发展的关键.开征房产税是重要手段,然试行的房产税存在严重误区,有使利器失效之危险.

    Between 1979/81 and 1999 livestock numbers increased throughout S.E. Asia and Tropical America despite the increasing human population density in these regions Indonesia, Myanmar and Thailand dominate the large ruminant population in S.E. Asia. . The large ruminant population in these countries is dwarfed by that in China. In tropical America Brazil, Colombia and Venezuela have the largest large ruminant populations . In S.E. Asia, between 1979/81 and 1999, cattle numbers increased by 91% but buffalo numbers decreased by 3%. The cattle population in Tropical America has increased by 19%. The largest small ruminant population in S. E. Asia occurs in Indonesia and, in Tropical America, in Brazil and Mexico. There has been a very significant (90%) increase in small ruminants in S.E. Asia. The major needs of the largely cut and carry systems used in much of S E Asia and Africa is to provide a year-round supply of high quality forages to supplement low quality crop residues and forages cut from roadsides and wastelands. Because of the reluctance of farmers to fertilise forages in these systems it is an imperative that the flow of nutrients from the soil to the plant and then to the animal be as efficient as possible. In the past legumes, particularly tree and shrub legumes, have been the preferred supplementary forage supply but as systems become more intensive increased attention needs to be paid to N fertilised grasses and direct supplementation of animals with N, P, and other nutrients. The research to be undertaken needs to trace the flow and balance of nutrients (particularly N,P,K,S,Zn and C) through the plant production cycle, particularly the recycling of nutrients when associated with carbon in crop residues and specialist supplementary fodder crops. Studies are also needed on the efficiency of animal feeding and nutrient utilisation, especially in the re- utilisation of manure, urine and bedding material in subsequent crop production.

    Preparation of Perovskite solar cell, an emerging low-cost photovoltaic technology in rapid development, has provided a ray of hope to solve the energy problem. However, its low reproducibility and stability limit the wide application of this potential technology. In this review, we summarize the recent progress with a focused discussion on some key issues in the development of perovskite solar cells. Starting from the analysis of basic structure and working principles, we first discuss the perovskite-based light harvesting layer and the general strategy to control its spectrum response. We also demonstrate the effect of film morphology on the device performance and the reproducibility which requires very uniform thin films. Then we discuss the major function of electron transporting layer and hole blocking layer, and point out the importance of compact hole blocking layer with less nano-scaled pinholes. For the hole transporting layer, we focus the discussion on the stability problem induced by widely used dopants that can improve the hole conductivity in the hole transporting layer while the dopants’ deliquescent behavior also can induce the decomposition of perovskite-based light harvesting layer with a rapid degradation of the whole device. The potential approaches to solve this stability problem, such as using a dopant-free hole transporting material or making device without any hole transporting materials, are also discussed. Finally, we are in prospect of overcoming the main challenges in the future research for high performance perovskite solar cells.%钙钛矿太阳电池的迅速发展为解决未来能源问题带来一线曙光。但是,钙钛矿太阳电池在高效率电池器件的可重现性、稳定性以及性能评估等方面还面临着很多问题,严重制约其今后的发展。本文综述了钙钛矿太阳电池面世以来发生的重要进展,以及存在的几个关键性问题。从器件基本结构和基本工作原理出

    2012-01-01

    Carbon dioxide (CO2) is the most important anthropogenic greenhouse gas and its global concentration in the atmosphere has increased since 1750s due to human activities. Agriculture is of relevance to climate change due to emissions in food production and emissions through land use change. The reduction in emissions of CO2 and the sequestration of atmospheric CO2 has become a hot issue and should be strongly pursued. "Biochar", biomass-derived black carbon (BC), has emerged as a potential strategy for climate change mitigation. Black carbon is a general term used to describe products derived from incomplete combustion of vegetation and fossil fuels. It is a continuum of carbon (C) forms and has high carbon content. A characteristic of biochar that is common to black carbon in general is that it comprises mainly stable aromatic forms of organic carbon. About 80% of BC produced from different sources ends up in soils and sediments where it resides for hundreds to thousands of years due to its resistance to biological and chemical breakdown. As a result, BC could be an alternative for us to fight against climate change. Active soil managements offers the possibility to increase terrestrial carbon stores in various forms in soils. Based on literature review, this paper described the sources of BC and its potential role to increase C storage in the soils. We emphasized the importance in quantifying BC and the key to determine content of BC in soils. In this paper the stability of BC in the soils was stated, and the interaction between the added BC and native soil organic matter as well as the effect of BC on soil greenhouse gas production was also discussed. The key to estimating BC stocks and its environmental performance in soils and sediments is an understanding of the implication of BC served an effective soil carbon pool, which can be useful for us to draw the conclusion on the role of BC in the global carbon cycle and agricultural carbon-negative process in China

    Full Text Available Since the mid 20th century, large urban areas in advanced economies have experienced a fundamental transformation from relatively compact monocentric cities towards more extended polycentric metropolitan areas. By now, it is being commented repeatedly, but not investigated systematically that the concept of polycentricity is also adequate to characterise recent metropolitan dynamics in Latin-America.This paper aims to present a few key-issues for a future research agenda into polycentricity in Latin-American metropolitan areas. These elements are identified from a review of existing literature. Since no clear-cut definition and operationalisation of polycentricity exist yet, we distinguish some key-elements of this phenomenon in North America as a frame of reference for this review. It reveals that ‘polycentricity U.S. style’ is at best dawning in Latin-America. In order to achieve a more appropriate picture of polycentricity of Latin American metropolitan areas, our ideas for a research agenda take into account these areas typical economic, social and spatial conditions.

    2016-03-01

    This article summarizes the regulatory scenario on biological medications in Latin America focusing on comparability studies, extrapolation of indications, interchangeability and pharmacovigilance issues. In the case of comparability studies, what is being discussed is the possibility of decreasing the clinical trials requirement, but that the molecule should be well characterized in the studies of pharmacokinetics and pharmacodynamics. With the worldwide-level approval of the first monoclonal antibody biosimilar, infliximab, extrapolation of indications are being discussed, since the behavior of the Latin America regulatory agencies has been different with regard to such issue. Another issue discussed by the regulatory agencies is the interchangeability between biological medications and their biosimilars, mainly due to the fact that there is a clear confusion on interchangeability and substitution concepts. Finally, the pharmacovigilance debate, according to what takes place globally, is related to the need for identifying and differentiating the reference biological medication and its biosimilars for traceability purposes.

    Full Text Available Flies (Diptera, blow flies, house flies, flesh flies, horse flies, cattle flies, deer flies, midges and mosquitoes are among the four megadiverse insect orders. Several species quickly colonize human cadavers and are potentially useful in forensic studies. One of the major problems with carrion fly identification is the lack of taxonomists or available keys that can identify even the most common species sometimes resulting in erroneous identification. Here we present a key to the adults of 12 families of Diptera whose species are found on carrion, including human corpses. Also, a summary for the most common families of forensic importance in South America, along with a key to the most common species of Calliphoridae, Muscidae, and Fanniidae and to the genera of Sarcophagidae are provided. Drawings of the most important characters for identification are also included.Diptera (califorídeos, sarcofagídeos, motucas, moscas comuns e mosquitos é a uma das quatro ordens megadiversas de insetos. Diversas espécies desta ordem podem rapidamente colonizar cadáveres humanos e são de utilidade potencial para estudos de entomologia forense. Um dos maiores problemas com moscas que visitam matéria orgânica animal em decomposição é a falta de taxonomistas ou chaves de identificação disponíveis que possam identificar as espécies mais comuns ou mesmo, algumas vezes podendo resultar em identificações errôneas. Neste artigo é apresentada uma chave para adultos de 12 famílias de Diptera com espécies encontradas em matéria orgânica animal em decomposição, incluindo cadáveres humanos. Também é incluído um sumário das mais importantes famílias com espécies de interesse forense na América do Sul e chave de identificação das espécies mais comuns de Calliphoridae, Muscidae e Fanniidae e dos gêneros de Sarcophagidae. Esquemas dos mais importantes caracteres utilizados para identificação dessas espécies são também incluídos.

Destacando-se a importância do amianto como um problema de Saúde Pública, pelo seu potencial carcinogênico reconhecido para os seres humanos, perpassando pela constituição de redes como contrapoderes em prol do banimento dessa fibra nociva, ressaltando a participação social nessa luta. O problema do amianto nas discussões das políticas públicas de saúde, trabalho e meio ambiente ainda permanece pouco claro no campo da Saúde do Trabalhador. Ao restringir a apenas um único campo de atuação, reduz-se a atuação das vigilâncias, como se estivesse apenas limitado ao ambiente de trabalho. É necessária então a discussão nos campos da Saúde Ambiental e da Saúde Publica. A ausência de políticas públicas contribui para a invisibilidade dos problemas relacionados ao amianto no Brasil. Hoje, as vítimas do amianto não têm suas doenças reconhecidas, e seus direitos são negados em várias instâncias do poder público. Conclui-se que a luta pelo fim da utilização dessa fibra e a redução das doenças provocadas pela mesma configuram-se um movimento político comprometido com a transformação social na busca por uma sociedade mais justa, igualitária e saudável.This article has the aim of rescuing the fight for the banishment of asbestos in Americas.

    Climate change mitigation can be implemented through the approach of engineering technologies at a large geographic scale. Geo-engineering refers to, in the large Earth yardstick or scale, all kinds of artificial approaches of engineering technologies in temperature reduction by removing CO2 in the atmosphere or directly controlling solar radiation, instead of emission reductions related to production and consumption of energy, and to the management of industrial production process. It is mainly classified into three big categories; approach of green biological technology, carbon capture and storage, and control and management technology of solar radiation. This kind of geo-engineering approach has a series of implications in economy, technology, environment, ethics, security, and uncertainty. The present paper makes an analysis and conducts a discussion on several recent international key issues of the possible technological options for mitigation of climate change, involving definitions of concept, technological features, possible effects and governance framework, etc.. The author argues that geo-engineering approach directly acting on carbon, such as biological sinks and carbon capture and storage technologies, are assessed with relatively low risk and high level of control. Through temperature reduction effects by artificially emitting SO, into the atmosphere and aerosols, solar radiation management technology is used to control the rise of the Earth's temperature, which, though having not a high economic cost of use but practical maneuverability, has huge uncertainty and possible implication of security, needing enough attention. Ethically, there are disputes over whether or not the contemporary people have the right to carry on geo-engineering of solar radiation management technology with such huge scientific uncertainty, and in such scientific uncertainty, to take any action will lose the ethnic basis. Legally, human intervention in solar radiation, even

The paper discusses the extent to which one can legitimately talk about "a Latin- American scientific specificity", supposedly resulting from peculiar theoretical approaches or even from particular socio-environmental features (such as widespread poverty and high rates of social inequality, along with unparalleled levels of biodiversity. Last but not least, the paper seeks to draw a sort of thematic map (via bibliographical review as well as a consideration of the levels of scientific institutionalization of environmental issues in six different research centers located in Argentina, Chile, Mexico, Uruguay and Brazil.Ao tratar a interdisciplinaridade e a área de ambiente e sociedade enquanto campos que lidam com questões científicas relacionadas com idéias, práticas, instituições e habitus (Bourdieu, esse artigo pretende contribuir para a compreensão dos processos multifacetados implicados na institucionalização da questão ambiental na academia e centros de pesquisa latino-americanos.

    2011-01-01

    "三农"问题彼此间存在着差异却又紧密联系,其核心是农民问题。作者基于政治经济学的研究方法对"三农"问题的成因进行了深入分析,指出了农民专业合作组织在破解"三农"问题中的重要作用。"三农"问题的本质是农民权利的缺失,而农民权利缺失的根本原因在于农民的组织化程度太低。所以,破解"三农"问题的关键在于提升我国农民的组织化程度。只有改变农民的弱势地位,发挥农民的主体作用,努力提高农民素质,增强其参与市场竞争和抵抗风险的能力,才能够增加农民收入,实现传统农业向现代农业的转变,加快建设社会主义新农村的步伐。而农民专业合作组织是农村经营中最具活力的组织载体,是推进农业产业化的主导力量和提高农民素质的有效途径。因此本研究通过对农民专业合作组织内部运行机制和外部发展环境障碍的分析,提出了健全机制、强化主体、培育人才、政策支持和改善融资等促进其作用发挥的相关举措。%Three Rural Issues have great relevancy but also have differences,in which the problem of farmers is the core issue.Based on the political economics research method,the article concluded the importance of specialized farmers cooperatives.Lack of farmers' rights,which related to the rarity of farmers organization,is the main cause of Three Rural Issues.Only by changing the farmers disadvantageous position,exerting their principal role,improving their quality and enhancing their participation in the market competition and their risk resistance,farmers' income could be increased,modern agriculture could be realized,and the pace of the new socialist rural construction could be sped up.Specialized farmers cooperatives are the most dynamic actors in rural management,and the leading power of promoting agriculture industrialization.Through analyzing internal operation mechanism and

    2010-04-01

    Key management is one of the most important issues in cryptographic systems. Several important challenges in such a context are represented by secure and efficient key generation, key distribution, as well as key revocation. Addressing such challenges requires a comprehensive solution which is robust, secure and efficient. Compared to traditional key management schemes, key management using biometrics requires the presence of the user, which can reduce fraud and protect the key better. In this paper, we propose a novel key management scheme using iris based biometrics. Our newly proposed scheme outperforms traditional key management schemes as well as some existing key-binding biometric schemes in terms of security, diversity and/or efficiency.

    2015-06-01

    Full Text Available The consolidation of the middle class has been interpreted by modernization and postmodernization theories as a key factor for the functioning and stability of the democratic system. However, in Latin America the middle class has tended to be associated with two contradictory positions. On the one hand, it is emphasized that it plays a stabilizing and democratic role while, on the other hand, it is linked to supporting military coups. With the purpose of elucidate such a dilemma, the relationship that can be established between the socioeconomic status and the degree of support for democracy will be examined. In order to do this, an empirical analysis from Latinbarometer surveys databases will be conducted, covering seventeen countries in the region for the period from 1996 to 2011. It will be concluded that the middle class in Latin America does not have particularly more favorable attitudes toward democracy than other social segments.

    The geography, tourist attractions and the multiple sites of historical and cultural interest make South America as an important destination chosen by travelers. The continent has a wide climatic variation from north to south, making exposure to risk different between the tropics and the temperate or cold regions. In the countries of tropical South America, the greatest risk is associated with the possibility of acquiring vector-borne diseases, like yellow fever, dengue, malaria and leishmaniasis. The risk of acquiring traveler's diarrhea and food-borne illness is similar across the continent, with some variations according to country and to visit urban or rural areas. Rabies, pertussis and diphtheria have appeared as epidemics in several countries and other diseases such as rickettsiosis, hantavirosis and viral encephalitis have expanded their distribution. The geographic and epidemiological diversity of South America, promotes a challenge for travel medicine specialists because during the pre-travel advice they have to take in account the kind of trip, traveller's medical history, exposure to risk and the dynamics of endemic emerging and reemerging diseases in the region.

    2016-10-01

    Three major problems of single-star astrophysics are convection, magnetic fields and rotation. Numerical simulations of convection in stars now have sufficient resolution to be truly turbulent, with effective Reynolds numbers of [Formula: see text], and some turbulent boundary layers have been resolved. Implications of these developments are discussed for stellar structure, evolution and explosion as supernovae. Methods for three-dimensional (3D) simulations of stars are compared and discussed for 3D atmospheres, solar rotation, core-collapse and stellar boundary layers. Reynolds-averaged Navier-Stokes (RANS) analysis of the numerical simulations has been shown to provide a novel and quantitative estimate of resolution errors. Present treatments of stellar boundaries require revision, even for early burning stages (e.g. for mixing regions during He-burning). As stellar core-collapse is approached, asymmetry and fluctuations grow, rendering spherically symmetric models of progenitors more unrealistic. Numerical resolution of several different types of three-dimensional (3D) stellar simulations are compared; it is suggested that core-collapse simulations may be under-resolved. The Rayleigh-Taylor instability in explosions has a deep connection to convection, for which the abundance structure in supernova remnants may provide evidence. PMID:27652516

  2. Key issues in controlling air pollutants in Dhaka, Bangladesh

    Science.gov (United States)

    Begum, Bilkis A.; Biswas, Swapan K.; Hopke, Philip K.

    2011-12-01

    Particulate matter (PM) sampling for both coarse and fine fractions was conducted in a semi-residential site (AECD) in Dhaka from February 2005 to December 2006. The samples were analyzed for mass, black carbon (BC), and elemental compositions. The resulting data set were analyzed for sources by Positive Matrix Factorization (EPA-PMF). From previous studies, it is found that, the air quality became worse in the dry winter period compared to the rainy season because of higher particulate matter concentration in the ambient air. Therefore, seasonal source contributions were determined from seasonally segregated data using EPA-PMF modeling so that further policy interventions can be undertaken to improve air quality. From the source apportionment results, it is observed that vehicular emissions and emission from brick kiln are the major contributors to air pollution in Dhaka especially in the dry seasons, while contribution from emissions from metal smelters increases during rainy seasons. The Government of Bangladesh is considering different interventions to reduce the emissions from those sources by adopting conversion of diesel/petrol vehicles to CNG, increasing traffic speed in the city and by introducing green technologies for brick production. However, in order to reduce the transboundary effect it is necessary to take action regionally.

  5. Key Issues Review: Numerical studies of turbulence in stars

    CERN Document Server

    Arnett, W David

    2016-01-01

    The numerical simulation of turbulence in stars has led to a rich set of possibilities regarding stellar pulsations, asteroseismology, thermonuclear yields, and formation of neutron stars and black holes. The breaking of symmetry by turbulent flow grows in amplitude as collapse is approached, which insures that the conditions at the onset of collapse are not spherical. This lack of spherical symmetry has important implications for the mechanism of explosion and ejected nucleosynthesis products. Numerical resolution of several different types of three--dimensional (3D) stellar simulations are compared; it is suggested that core collapse simulations may be under-resolved. New physical effects which appear in 3D are summarized. Connections between simulations of progenitor explosion and observations of supernova remnants (SNR) are discussed. Present treatment of boundaries, for mixing regions during He--burning, requires revision.

  8. Data payload optimality: a key issue for video watermarking applications

    Science.gov (United States)

    Mitrea, M.; Duta, S.; Prêteux, F.; Vlad, A.

    2006-08-01

    Watermarking aims at enforcing property right for digital video: a mark is imperceptibly - transparently - embedded into original data. The true owner is identified by detecting this mark. The robust watermarking techniques allow the mark detection even when the protected video is attacked. Transparency and robustness constraints restrict the mark size: the better transparency and robustness, the smaller the data payload. The paper presents a method to evaluate the maximum quantity of information which can be theoretically inserted into the 2D-DCT coefficient hierarchy, for prescribed transparency and robustness. This approach relies on the noisy channel model for watermarking. Within this mathematical framework, the maximal data payload is expressed by the channel capacity. As any capacity evaluation procedure requires an intimate knowledge of the noise sources, the paper first describes the developed statistical approach enabling: (1) to properly handle the inner dependency existing among successive frames in a video sequence, and (2) to accurately check out the Gaussian behaviour for each noise source. The experiments were carried out in partnership with the SFR mobile service provider in France (Vodafone group).

    Full Text Available Prostate cancer is is the most common solid neoplasm and it is now recognized as one of the most important medical problems facing the male population. Due to its long latency and its identifiable preneoplastic lesions, prostate cancer is an ideal target tumor for chemoprevention. Different compounds are available and certainly polyphenols represent those with efficacy against prostate cancer. This review take a look at activity and properties of major polyphenolic substances, such as epigallocatechin-3-gallate, curcumin, resveratrol and the flavonoids quercetin and genistein. Although the current studies are limited, mechanisms of action of polyphenols added with the lack of side effects show a a start for future strategies in prostate chemoprevention.

    2011-05-15

    In recent years research activities are intensively focused on renewable fuels in order to fulfill the increasing energy demand and to reduce the fossil fuels consumption and external oil dependency either in order to provide local energetic resources and or as a means for reducing greenhouse gases (GHG) emissions to reduce the climate change effects. Among the various renewable energy sources algal biofuels is a very promising source of biomass as algae sequester huge quantities of carbon from atmosphere and are very efficient in utilizing the nutrients from the industrial effluent and municipal wastewater. Algae capture CO{sub 2} from atmosphere and industrial flue gases and transform it in to organic biomass that can be used for the production of biofuels. Like other biomass, algal biomass is also a carbon neutral source for the production of bioenergy. Therefore cultivation of algal biomass provides dual benefits; while being able to utilize nutrients in waste water thus reducing impacts on inland waters it produce biomass for the production of biofuels. However, reaching commercial scale production of algal biofuels is difficult. The main drawbacks include the harvesting of dry biomass and higher capital investment. The harvested algal biomass and its extracts can be efficiently converted to different biofuels such as bioethanol, biodiesel, biogas and biohydrogen by implementation of various process technologies. Comprehensive life cycle assessments (LCA) of algal biofuels illustrating environmental benefits and impacts can be a tool for policy decisions and for technology development. (Author)

    The theoretical issues in the interpretation of the precision measurements of the nucleon-to-Delta transition by means of electromagnetic probes are highlighted. The results of these measurements are confronted with the state-of-the-art calculations based on chiral effective-field theories (EFT), lattice QCD, large-Nc relations, perturbative QCD, and QCD-inspired models. The link of the nucleon-to-Delta form factors to generalized parton distributions (GPDs) is also discussed.

  3. Miscellaneous issues

    International Nuclear Information System (INIS)

    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

  9. Intelligent card access keys

    International Nuclear Information System (INIS)

    A newly developed access control technology allows information about users to be stored on key-like EEPROM devices. The keys store encrypted information about the user and his or her authorized access activity. Specially developed key readers scan, decrypt, and process the key data, and make the decision whether entry should be granted or denied. The key readers can function as complete, stand-alone facility management systems, incorporating access control, security monitoring, and remote control. In this configuration, the key readers provide anti-passback protection and other special features without requiring any data lines between readers. The key readers also feature sophisticated algorithmic processing for performing complex operations such as two-man control or cross zoned security annunciation. Key readers can also be interconnected with an MCM-1000 Multiples Monitoring System to form a distributed processing local area network. In such a configuration, changes in key reader status can be uploaded to the MCM-1000, and programming changes and operator commands can be downloaded to the key readers

  10. Synopsis of the Review on Space Weather in Latin America: Space Science, Research Networks and Space Weather Center

    Science.gov (United States)

    Denardini, Clezio Marcos; Dasso, Sergio; Gonzalez-Esparza, Americo

    2016-07-01

    The present work is a synopsis of a three-part review on space weather in Latin America. The first paper (part 1) comprises the evolution of several Latin American institutions investing in space science since the 1960's, focusing on the solar-terrestrial interactions, which today is commonly called space weather. Despite recognizing advances in space research in all of Latin America, this part 1 is restricted to the development observed in three countries in particular (Argentina, Brazil and Mexico), due to the fact that these countries have recently developed operational centers for monitoring space weather. The review starts with a brief summary of the first groups to start working with space science in Latin America. This first part of the review closes with the current status and the research interests of these groups, which are described in relation to the most significant works and challenges of the next decade in order to aid in the solving of space weather open issues. The second paper (part 2) comprises a summary of scientific challenges in space weather research that are considered to be open scientific questions and how they are being addressed in terms of instrumentation by the international community, including the Latin American groups. We also provide an inventory of the networks and collaborations being constructed in Latin America, including details on the data processing, capabilities and a basic description of the resulting variables. These instrumental networks currently used for space science research are gradually being incorporated into the space weather monitoring data pipelines as their data provides key variables for monitoring and forecasting space weather, which allow these centers to monitor space weather and issue warnings and alerts. The third paper (part 3) presents the decision process for the spinning off of space weather prediction centers from space science groups with our interpretation of the reason/opportunities that leads to

    Newcomer health and health care are policy issues with major outcomes of cost shifting and enormous consequences for newcomers and the community health nurses who promise them care. Newcomers are persons entering U.S. borders who could be asylees, refugees, immigrants, legal or illegal aliens, migrants, international adoptees, and others. Described in this article are the role federalism has played on the interplay among policymakers regarding newcomer health. Also addressed is newcomer health policy, including immigration policies, and newcomer health issues such as infectious diseases and questionable health care. Additional newcomer health issues such as newcomers at high risk for health problems, issues of access to care for newcomers, and welfare reform policies are discussed. Newcomer health and special interest group activities such as those from medicine and nursing are also addressed. Finally, meaningful options and possible solutions for newcomer health care concerns are identified and shared.

    This regional study is comprised of three case studies, which concentrate on Greater Buenos Aires, Caracas and Rio de Janeiro - Caju. Each case focuses on the analysis of specific aspects of urban poverty, energy availability and policies to improve living conditions from the energy point of view. Unlike other developing regions in the world, the problem of energy poverty in Latin America has been concentrated increasingly in the large cities and urban areas. This problem has deep systemic, economic, political, structural and cultural roots. Providing basic energy services to the urban poor is an issue that requires far more attention and expertise than it is receiving today, and therefore WEC has taken the initiative to address this issue, and the results of their study are presented in this report.

    There are various challenges that are faced in group communication, so it is necessary to ensure session key. Key agreement is the fundamental cryptographic primitive for establishing a secure communication. It is a process of computing a shared secret contributed by two or more entities such that no single node can predetermine the resulting value. An authenticated key agreement is attained by combining the key agreement protocol with digital signatures. After a brief introduction to existing key agreement in group communication, Making use of the additive-multiplicative homomorphism in the integer ring defined by Sander and Tschudin: A new protocols, called the homomorphism key agreement, was designed, which can be self-contributory, robust, scalable and applicable in group communication.

  17. Can Latin America fill the U.S. polyolefin deficit?

    International Nuclear Information System (INIS)

    Strategic issues for the North American polyolefin industry were discussed with reference to oil and gas price forecasts, oil capacity increases, and high density polyethylene production and ethylene integration costs. The overall polyolefin trade balance in North America was also explored. It was cautioned that unless a significant amount of new capacity is built in the United States, it is anticipated that by 2008, the United States will become a net importer of polyolefin resins. Currently exported product will be used increasingly in the domestic market to meet demand growth. This shift from being a net exporter of resins can be attributed to the high cost of feedstocks and the lack of investment in new capacity throughout the region. In contrast, there have been several proposals for new capacity in Latin America in the past several years. Since there is already an important level of commerce and trade between North and South America, countries with access to the Caribbean basin, are logistically well situated to serve the North American market. The availability of low cost feedstocks in countries such as Trinidad, Venezuela and Bolivia add to the attractiveness of the region for the development of new petrochemical capacity. This paper examined the status of the different proposed projects in Latin America and analyzed the potential opportunities that exist for North American producers to collaborate in those projects. The general trade balance of the continent was reviewed in order to verify if the traditional seclusion of America's polyolefin market can be maintained in the future. It was concluded that even if all projects in Latin America are launched, the Americas will still be in a net deficit position. Under the right circumstances, the Middle East will be the global supplier of commodity polyolefins that could extend to the Americas. It was emphasized that companies should be prepared for feedstock advantaged investments, alliances, acquisitions and

    Recent studies have suggested that the first arrival of humans in the Americas during the end of the last Ice Age is associated with marked anthropogenic influences on landscape; in particular, with the use of fire which, would have given even small populations the ability to have broad impacts on the landscape. Understanding the impact of these early people is complicated by the dramatic changes in climate occurring with the shift from glacial to interglacial conditions. Despite these difficulties, we here attempt to test the extent of anthropogenic influence using the California Channel Islands as a smaller, landscape-scale test bed. These islands are famous for the discovery of the 'Arlington Springs Man', which are some of the earliest human remains in the Americas. A unifying sedimentary charcoal record is presented from Arlington Canyon, Santa Rosa Island, based on over 20 detailed sedimentary sections from eight key localities. Radiocarbon dating was based on thin, fragile, long fragments of charcoal in order to avoid the 'inbuilt' age problem. Radiocarbon dating of 49 such fragments has allowed inferences regarding the fire and landscape history of the Canyon ca 19-11 ka BP. A significant period of charcoal deposition is identified approximately 14-12.5 ka BP and bears remarkable closeness to an estimated age range of the first human arrival on the islands.This article is part of the themed issue 'The interaction of fire and mankind'.

    2003-08-01

    Latin America undoubtedly has comparative advantages in the fields of animal production, animal health and the production of food of animal origin. However, countries in Latin America must build on these strengths if the continent is to become more competitive and be able to deal with the complexities of world markets. To do this, Veterinary Services must define their objectives and establish quality standards on which to base their work. For this to occur, the State must create well-defined regulations, establish systems of audit and find ways of working which allow for a high degree of coordination and collaboration between the public and private sectors. This should be done within a framework of a quality assurance system, which allows for responsible accreditation and independent audit and evaluation. The author discusses the approaches of the different countries in the region to animal health, zoonosis, food safety, veterinary drugs control, animal welfare and export-import control. All programmes relating to these issues must be based on technical information gained through epidemiological surveillance, the network of diagnostic laboratories, quarantine systems, risk analysis, identification and traceability of animals and animal products, registration and control of veterinary drugs, and food safety research. In some countries these systems are already being developed. Maintaining good international relations and cooperating with neighbouring countries is always a challenge for official Veterinary Services and international organisations such as the OIE (World organisation for animal health) have a key role to play in facilitating these relationships.

    NOAM-SOIL is being created by combining the CONUS-SOIL database with pedon data and soil geographic data coverages from Canada and Mexico. Completion of the in-progress NOrth AMerica Soil (NOAM-SOIL) database will provide complete North America coverage comparable to CONUS. Canadian pedons, which number more than 500, have been painstakingly transcribed to a common format, from hardcopy, and key- entered. These data, along with map unit polygons from the 1:1,000,000 Soil Landscapes of Canada, will be used to create the required spatial data coverages. The Mexico data utilizes the INEGI 1:1,000,000 scale soil map that was digitized by U. S. Geological Survey EROS Data Center in the mid 1990's plus about 20,000 pedons. The pedon data were published on the reverse side of the paper 1:250,000 scale Soil Map of Mexico and key entered by USDA and georeferenced by Penn State to develop an attribute database that can be linked to the 1:1,000,000 scale Soil Map of Mexico based on taxonomic information and geographic proximity. The essential properties that will be included in the NOAM-SOIL data base are: layer thickness (depth to bedrock or reported soil depth); available water capacity; sand, silt, clay; rock fragment volume; and bulk density. For quality assurance purposes, Canadian and Mexican soil scientists will provide peer review of the work. The NOAM-SOIL project will provide a standard reference dataset of soil properties for use at 1km resolution by NACP modelers for all of North America. All data resources, including metadata and selected raw data, will be provided through the Penn State web site: Soil Information for Environmental Modeling and Ecosystem Management (www.soilinfo.psu.edu). Progress on database completion is reported.

    2006-09-01

    As Director of Fermilab, starting in 1979, I began a series of meetings with scientists in Latin America. The motivation was to stir collaboration in the field of high energy particle physics, the central focus of Fermilab. In the next 13 years, these Pan American Symposia stirred much discussion of the use of modern physics, created several groups to do collaborative research at Fermilab, and often centralized facilities and, today, still provides the possibility for much more productive North-South collaboration in research and education. In 1992, I handed these activities over to the AAAS, as President. This would, I hoped, broaden areas of collaboration. Such collaboration is unfortunately very sensitive to political events. In a rational world, it would be the rewards, cultural and economic, of collaboration that would modulate political relations. We are not there yet.

    Restrepo, H E; Llanos, G; Contreras, A; Rocabado, F; Gross, S; Suárez, J; González, J

    1995-09-01

    This article describes the Healthy Municipios movement in Latin America and gives examples of some PAHO projects that could become demonstration projects. The Healthy Municipios movement was established in the early 1990s. The movement aims to promote healthy municipalities according to objectives set forth in the 1987 Ottawa Charter on Health Promotion, the 1992 Declaration of Bogota, and the 1993 Caribbean Health Promotion Charter. The movement is a joint effort of government, the health sector, and the community in promoting health locally. Key features of the movement are its creativity, variety, political strength, and adaptation to local conditions. Technical cooperation serves the purpose of facilitating information exchange and promotes the use of modern techniques of analysis and scientific and technical information. All projects shared the following common features: initiation by the local community with strong political commitment, intersectoral organizational structure, widespread community mobilization and participation, problem solving activities, and a recognizable leader. Pioneering projects include the Comprehensive Project for Cienfuegos, Cuba; the Health Manizales, Colombia; the Network in Mexico; Baruta and El Hatillo, Venezuela; Valdivia, Chile; and San Carlos Canton, Costa Rica. It is concluded that these projects and most others aim to assure equity. These efforts are important for placing health on the political agenda and implementing healthy policies. The Valdivia project, for example, serves a population of about 120,000 in the urban city of Valdivia, the semi-urban area, and rural areas. The project was officially sanctioned by the President of Chile on World Health Day in 1993. Progress was reported in mass communication and school-based programs. Attention was directed also to prevention of risk factors for noncommunicable diseases and to the problem of traffic accidents.

  13. Projected refined product balances in key Latin American countries: A preliminary examination

    Energy Technology Data Exchange (ETDEWEB)

    1996-06-01

    Over the years, the East-West Center (EWC) has developed considerable expertise in refinery modeling, especially in the area of forecasting product balances for countries, given planned capacity changes, changes in product demand, changes in crude slates, and changes in product specifications. This expertise has been applied on an ongoing basis to the major refiners in the Middle East and the Asia-Pacific region, along with the US West Coast as region in its own right. Refinery modeling in these three areas has been ongoing for nearly 15 years at the Center, and the tools and information sources are now well developed. To date, the EWC has not applied these tools to Latin America. Although research on Latin America has been an ongoing area of concern at the Center in recent years, the information gathered to date is still not of the level of detail nor quality available for other areas. The modeling efforts undertaken in this report are of a ``baseline`` nature, designed to outline the major issues, attempt a first cut at emerging product balances, and, above all, to elicit commentary from those directly involved in the oil industry in the key countries modeled. Our experience in other regions has shown that it takes a few years dialogue with refiners and government planner in individual countries to develop a reliable database, as well as the insights into operational constraints and practices that make accurate modeling possible. This report is no more than a first step down the road.

    2011-06-01

    Full Text Available Neoliberalism in Latin America. Neoliberalism and globalization had decisive influence in shaping public policies both internal and foreign in Latin America. Less state, trade and market freedoms, social goals subordinated to economic criteria, are part and parcel of the neoliberal utopia. Price stability was erected as the main social objective; import substitution resulted replaced by exports as the main source of growth. The neoliberal net results as applied to Latin America are: less growth, deindustrialization, income concentration and precarious employments. Therefore, countries public policies should try to gain autonomy to use jointly markets and public intervention in a constructive and innovative fashion.

  15. Reagan issues mineral policy

    Science.gov (United States)

    The National Materials and Minerals Program plan and report that President Reagan sent to Congress on April 5 aims to ‘decrease America's minerals vulnerability’ while reducing future dependence on potentially unstable foreign sources of minerals. These goals would be accomplished by taking inventory of federal lands to determine mineral potential; by meeting the stockpile goals set by the Strategic and Critical Material Stockpiling Act; and by establishing a business and political climate that would encourage private-sector research and development on minerals.Now that the Administration has issued its plan, the Subcommittee on Mines and Mining of the House Committee on Interior and Insular Affairs will consider the National Minerals Security Act (NMSA), which was introduced 1 year ago by subcommittee chairman Jim Santini (D-Nev.)

The bill calls for establishing a three-member White-House-level council to coordinate the development of a national minerals policy; amending tax laws to assist the mining industry to make capital investments to locate and produce strategic materials; and creating a revolving fund for the sale and purchase of strategic minerals. In addition, the NMSA bill would allow the secretary of the interior to make previously withdrawn public lands available for mineral development. The subcommittee will hold a hearing on the Administration's plan on May 11. Interior Secretary James Watt has been invited to testify.

    Peripheral neuropathy is a common neurological disorder. There may be important differences and similarities in the diagnosis of peripheral neuropathy between North America (NA) and South America (SA). Neuromuscular databases were searched for neuropathy diagnosis at two North American sites, University of Kansas Medical Center and University of Texas Southwestern Medical Center, and one South American site, Federal Fluminense University in Brazil. All patients were included into one of the six major categories: immune-mediated, diabetic, hereditary, infectious/inflammatory, systemic/metabolic/toxic (not diabetic) and cryptogenic. A comparison of the number of patients in each category was made between North America and South America databases. Total number of cases in North America was 1090 and in South America was 1034 [immune-mediated: NA 215 (19.7%), SA 191 (18%); diabetic: NA 148 (13.5%), SA 236 (23%); hereditary: NA 292 (26.7%), SA 103 (10%); infectious/inflammatory: NA 53 (4.8%), SA 141 (14%); systemic/metabolic/toxic: NA 71 (6.5%), SA 124 (12%); cryptogenic: NA 311 (28.5%), SA 239 (23%)]. Some specific neuropathy comparisons were hereditary neuropathies [Charcot-Marie-Tooth (CMT) cases] in NA 246/292 (84.2%) and SA 60/103 (58%); familial amyloid neuropathy in SA 31/103 (30%) and none in NA. Among infectious neuropathies, cases of human T-lymphotropic virus type 1 (HTLV-1) neuropathy in SA were 36/141(25%), Chagas disease in SA were 13/141(9%) and none for either in NA; cases of neuropathy due to leprosy in NA were 26/53 (49%) and in SA were 39/141(28%). South American tertiary care centers are more likely to see patients with infectious, diabetic and hereditary disorders such as familial amyloid neuropathies. North American tertiary centers are more likely to see patients with CMT. Immune neuropathies and cryptogenic neuropathies were seen equally in North America and South America.

  17. Energy security in South America and Southern Africa: synthesis report

    International Nuclear Information System (INIS)

    In developing countries, the ability to provide adequate and reliable energy supplies is a key to sustainable economic development. The aim of this report is to study the energy supply security in both Southern Africa and South America and how these regions can participate in the international effort to combat climate change. This report showed that South Africa's energy sector mostly relies on carbon intensive coal while Brazil is mainly supplied by hydroelectricity. It was found that in both countries energy needs will increase significantly due to rising demand both internally and at a regional scale. However it was also shown that both Southern Africa and South America have important hydro, solar and wind renewable resources which could enhance their electricity security while minimizing their environmental impacts. This study demonstrated that Southern Africa and South America can enhance their electricity security through the use of renewable energies but that technology and financing is needed to develop the sector.

    2006-01-01

    Protocols for key management are compared and evaluated from the point of view on mobile ad hoc networks (MANET). The issues of fault-tolerance and efficiency of key distribution protocols for group communications in MANET are addressed. Most key distribution protocols existing today are primarily designed for wire-line networks. These protocols either fail to work as intended or cannot work at all when they are applied to the demanding environment of MANET. Parameters and performance of different protocols are analyzed, and then a flat is given out, on which new protocols or existing ones are designed and modified, so that they can be robust, scalable and efficient in MANET.

  4. Geoparks in Latin America

    International Nuclear Information System (INIS)

    A Geopark is a territory delimited part of a holistic concept of protection, education and sustainable development, based on geological sites of particular importance, rarity or aesthetic geological sites. A Geopark achieves its goals through three main areas: geoconservation, education and geotourism. The first network of Geoparks born in Europe in 2000, and from 2004 UNESCO is promoting the creation of a Global Geoparks Network (Global Geoparks Network, GGN ). Currently, there are 64 Global Geoparks in 19 countries, and the movement is in full development. In Latin America there is hardly Araripe Geopark in Brazil. Presented in this work, projects and studies related to the development of Geoparks in Argentina, Brazil, Chile, Costa Rica, Peru and Venezuela. We understand that Colombia, Cuba, Ecuador, Mexico and Nicaragua have projects in this line, but the details are not yet readily available. The authors invite geoscientists and professionals in related fields to join a movement for the creation of the Latin American Network of Geoparks, intended as a framework for the conservation, sustainable use and disclosure of our national geological heritage

    For the last 25 years, every two to three years the Conferencia Latinoamericana de Geofísica Espacial (COLAGE) is held in one of the Latin American countries for the purpose of promoting scientific exchange among scientists of the region and to encourage continued research that is unique to this area of the world. At the more recent conference, the community realized that many individuals both within and outside Latin America have contributed greatly to the understanding of the space sciences in this area of the world. It was therefore decided to assemble a Special Issue Space and Geophysical Physics related to Latin America, presenting recent results and where submissions would be accepted from the world wide community of scientists involved in research appropriate to Latin America. Because of the large number of submissions, these papers have been printed in two separate issues. The first issue was published in Advances in Space Research, Vol. 57, number 6 and contained 15 papers. This is the second issue and contains 25 additional papers. These papers show the wide variety of research, both theoretical and applied, that is currently being developed or related to space and geophysical sciences in the Sub-Continent.

    Key issues that must be considered before a new contraceptive is introduced center on the need for a trained provider to begin or terminate the method, its side effects, duration of use, method's ability to meet users' needs and preferences, and extra training or staff requirements. Logistics and economic issues to consider are identifying a dependable way of effectively supplying commodities, planning extra services needed for the method, and cost of providing the method. Each contraceptive method presents a different side effect pattern and burdens the service delivery setting differently. The strategy developed to introduce or expand the 3-month injectable Depo-Provera (DMPA) can be used for any method. It includes a needs assessment and addresses regulatory issues, service delivery policies and procedures, information and training, evaluation, and other concerns. Viet Nam's needs assessment showed that Norplant should not be introduced until the service delivery system becomes stronger. Any needs assessment for expansion of contraceptive services should cover sexually transmitted disease/HIV issues. A World Health Organization strategy helps officials identify the best method mix for local situations. Introductory strategies must aim to improve the quality of family planning programs and expand choices. Many begin by examining existing data and conducting interviews with policymakers, users, providers, and women's health advocates. Introductory programs for Norplant focus on provider training, adequate counseling and informed consent for users, and ready access to removal. They need a well-prepared service delivery infrastructure. The first phase of the DMPA introductory strategy for the Philippines comprised a social marketing campaign and DMPA introduction at public clinics in 10 pilot areas with strong service delivery. Successful AIDS prevention programs show that people tend to use barrier methods when they are available. USAID is currently studying

We identify the main institutions involved in this research in the third section. Finally, in conclusion we offer suggestions that we consider to be of greatest priority for the future of educational research in Latin America.

  18. Boundary issues

    Townsend, Alan R.; Porder, Stephen

    2011-03-01

    What is our point of no return? Caesar proclaimed 'the die is cast' while crossing the Rubicon, but rarely does modern society find so visible a threshold in our continued degradation of ecosystems and the services they provide. Humans have always used their surroundings to make a living— sometimes successfully, sometimes not (Diamond 2005)—and we intuitively know that there are boundaries to our exploitation. But defining these boundaries has been a challenge since Malthus first prophesied that nature would limit the human population (Malthus 1798). In 2009, Rockström and colleagues tried to quantify what the 6.8 billion (and counting) of us could continue to get away with, and what we couldn't (Rockström et al 2009). In selecting ten 'planetary boundaries', the authors contend that a sustainable human enterprise requires treating a number of environmental thresholds as points of no return. They suggest we breach these Rubicons at our own peril, and that we've already crossed three: biodiversity loss, atmospheric CO2, and disruption of the global nitrogen (N) cycle. As they clearly hoped, the very act of setting targets has provoked scientific inquiry about their accuracy, and about the value of hard targets in the first place (Schlesinger 2009). Such debate is a good thing. Despite recent emphasis on the science of human-ecosystem interactions, understanding of our planetary boundaries is still in its infancy, and controversy can speed scientific progress (Engelhardt and Caplan 1987). A few weeks ago in this journal, Carpenter and Bennett (2011) took aim at one of the more controversial boundaries in the Rockström analysis: that for human alteration of the global phosphorus (P) cycle. Rockström's group chose riverine P export as the key indicator, suggesting that humans should not exceed a value that could trigger widespread marine anoxic events—and asserting that we have not yet crossed this threshold. There are defensible reasons for a marine

  1. Freshwater sponges (Porifera, Demospongiae indicators of some coastal habitats in South America: redescriptions and key to identification Esponjas de água doce (Porifera, Demonspongiae indicadoras de alguns ambientes costeiros na América do Sul: redescrição e chave para identificação

    Directory of Open Access Journals (Sweden)

    Cecilia Volkmer-Ribeiro

    Full Text Available Surveys for freshwater sponges were performed at several water bodies at sandy environments along a north-south direction of particularly the Brazilian coastal line. The results allowed for the distinction of four different species-specific environments along this coastal border. The main fact considered was the dominant or the sole recurrent occurrence of a single sponge species at one particular habitat. The first one is that of the lagoonal mesohaline habitats at the tropical and subtropical realms, indicated by Spongilla alba Carter, 1849. The second one refers to shallow ponds among dunes at the tropical area indicated by Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974. The third one is that of also shallow ponds close to the dune belt at the temperate region indicated by Racekiela sheilae (Volkmer-Ribeiro, De Rosa-Barbosa & Tavares, 1988. The fourth one is that of organically enriched environments, at the marginal areas of lagoons and mouth of small rivers, evolving towards freshwater muddy ponds and coastal swamps, not far from the ocean border: Ephydatia facunda Weltner, 1895 is the species to occupy this habitat with almost exclusiveness. The above species are thus proposed as indicators of such habitats and have their descriptions improved and that of their environments summarized. A taxonomic key based on the spicules of the four species is proposed. The results presented aim to contribute to the identification of spicules of these sponges in sediment columns recovered at the Brazilian and South American coastal area. Determination of paleo ocean borders are a present issue of upmost importance in what respects projections of timing and fluctuations of ascending/regressing sea levels.Levantamentos para detecção de esponjas dulcícolas foram conduzidos em diversos corpos d'água da faixa arenosa costeira, de norte a sul, particularmente no Brasil.

    Sacanna, S; Irvine, W T M; Chaikin, P M; Pine, D J

    2010-03-25

    New functional materials can in principle be created using colloids that self-assemble into a desired structure by means of a programmable recognition and binding scheme. This idea has been explored by attaching 'programmed' DNA strands to nanometre- and micrometre- sized particles and then using DNA hybridization to direct the placement of the particles in the final assembly. Here we demonstrate an alternative recognition mechanism for directing the assembly of composite structures, based on particles with complementary shapes. Our system, which uses Fischer's lock-and-key principle, employs colloidal spheres as keys and monodisperse colloidal particles with a spherical cavity as locks that bind spontaneously and reversibly via the depletion interaction. The lock-and-key binding is specific because it is controlled by how closely the size of a spherical colloidal key particle matches the radius of the spherical cavity of the lock particle. The strength of the binding can be further tuned by adjusting the solution composition or temperature. The composite assemblies have the unique feature of having flexible bonds, allowing us to produce flexible dimeric, trimeric and tetrameric colloidal molecules as well as more complex colloidal polymers. We expect that this lock-and-key recognition mechanism will find wider use as a means of programming and directing colloidal self-assembly. PMID:20336142

  4. Nature and causes of Quaternary climate variation of tropical South America

    Science.gov (United States)

    Baker, Paul A.; Fritz, Sherilyn C.

    2015-09-01

    This selective review of the Quaternary paleoclimate of the South American summer monsoon (SASM) domain presents viewpoints regarding a range of key issues in the field, many of which are unresolved and some of which are controversial. (1) El Niño-Southern Oscillation variability, while the most important global-scale mode of interannual climate variation, is insufficient to explain most of the variation of tropical South American climate observed in both the instrumental and the paleoclimate records. (2) Significant climate variation in tropical South America occurs on seasonal to orbital (i.e. multi-millennial) time scales as a result of sea-surface temperature (SST) variation and ocean-atmosphere interactions of the tropical Atlantic. (3) Decadal-scale climate variability, linked with this tropical Atlantic variability, has been a persistent characteristic of climate in tropical South America for at least the past half millennium, and likely, far beyond. (4) Centennial-to-millennial climate events in tropical South America were of longer duration and, perhaps, larger amplitude than any observed in the instrumental period, which is little more than a century long in tropical South America. These were superimposed upon both precession-paced insolation changes that caused significant variation in SASM precipitation and eccentricity-paced global glacial boundary conditions that caused significant changes in the tropical South American moisture balance. As a result, river sediment and water discharge increased and decreased across tropical South America, lake levels rose and fell, paleolakes arose and disappeared on the Altiplano, glaciers waxed and waned in the tropical Andes, and the tropical rainforest underwent significant changes in composition and extent. To further evaluate climate forcing over the last glacial cycle (˜125 ka), we developed a climate forcing model that combines summer insolation forcing and a proxy for North Atlantic SST forcing to

  5. Poultry welfare scenario in South America: norms and regulations

    Directory of Open Access Journals (Sweden)

    RBTR Silva

    2011-06-01

    Full Text Available Animal welfare related issues have been intensely discussed in recent years as a consequence of changes in public attitudes and regulatory reforms that are taking place in many countries. A combination of public opinion pressure and trade policy has driven requirements for regulation and the World Trade Organization (WTO assigned the World Organization for Animal Health (OIE to develop guidelines that could be used as international standards. However, trade disputes related to animal welfare are not likely to be resolved under the auspices of OIE, and access to international markets may be questioned in a way that does not necessarily reflect attitudes to animal production in emerging economies, such as those in South America. This paper presents an overall view of basic welfare issues and points out specific items related to the present scenario of norms and regulations that are being implemented in South America, where the growing poultry industry is an important economic activity.

    Manuel Chiriboga

    2013-09-01

    Full Text Available This article draws from the preliminary findings of an ongoing appliedresearch program on rural territorial dynamics carried out by the Latin American Center for Rural Development (RIMISP. The article provides some initial findings on 4 territories, of the 11 territories that are part of the overall study. The case studies include the island of Chiloé in southern Chile, the province of Tungurahua in Ecuador, a dairy farm region of Santo Tomás Nicaragua and Cuatro Lagunas near Cuzco Perú. Rural areas in Latin America are characterized by their dual nature with agro-exporting enclaves linked to global value chains alongside impoverished peasant economies, leading to differentiated policy recommendations. The research attempts to find relationships between reduced poverty and inequality in winning regions, measured by three variables, with issues of access to resources, human capital, political empowerment, markets and institutions, with particular attention to innovative social coalitions.

    The scope of this study is to question the fact that in some countries in Latin America (Chile, El Salvador, Nicaragua, Honduras and the Dominican Republic) abortion is still forbidden in all situations. Even after all the debate on this thorny issue, the theory of human rights is not often used in the defense of abortion.

    During a sharing session which took place at a conference sponsored by the Philippine Institute for Social Studies and Action in 1991, Peruvian Victoria Villanueva and US citizen Margaret Ann Schuller discussed their work. Schuller reported on her upcoming book entitled "Freedom from Violence: Women's Strategies Around the World." In addition to proposing a definition of violence against women, the book will include 12 case studies from Malaysia, Bolivia, Mexico, India, Pakistan, Thailand, Sri Lanka, Brazil, Zimbabwe, Chile, Africa, and Alaska describing how national organizations of women are dealing with the problem. An important advance is the development of a framework to look at the connection which exists between violence and health issues. Villanueva described the work of the Movimiento Manuela Ramos, which was organized informally to deal with reproductive rights and abortion and has since expanded to parent groups of women who defend legal and medical cases as paid paralegals. Manuela Ramos uses popular media, traditional drama, and even state television to publicize its issues. Manuela Ramos has accomplished important work on rape, unsafe abortion, and maternal mortality, but most importantly, the women involved with the organization have had the opportunity to develop their self-esteem.

  20. Anaglyph, North America

    Science.gov (United States)

    2003-01-01

    This anaglyph (stereoscopic view) of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent.Active tectonics (structural deformation of the Earth's crust) along and near the Pacific North American plate boundary creates the great topographic relief seen along the Pacific coast. Earth's crustal plates converge in southern Mexico and in the northwest United States, melting the crust and producing volcanic cones. Along the California coast, the plates are sliding laterally past each other, producing a pattern of slices within the San Andreas fault system. And, where the plates are diverging, the crust appears torn apart as one huge tear along the Gulf of California (northwest Mexico), and as the several fractures comprising the Basin and Range province (in and around Nevada).Across the Great Plains, erosional patterns dominate, with stream channels surrounding and penetrating the remnants of older smooth slopes east of the Rocky Mountains. This same erosion process is exposing the bedrock structural patterns of the Black Hills in South Dakota and the Ozark Mountains in Arkansas. Lateral erosion and sediment deposition by the Mississippi River has produced the flatlands of the lower Mississippi Valley and the Mississippi Delta.To the north, evidence of the glaciers of the last ice age is widely found, particularly east of the Canadian Rocky Mountains and around the

    Henan Province, as a large province of livestock husbandry, is playing an important role in the production of livestock husbandry in China. Although Henan province owns prominent advantages in industry foundation, locational advantages, natural resources superiority, and investment environment, it is still not the strong in the production of livestock husbandry due to the constraints of several key issues including monetary shortage, weak infrastructure,excrement wastes pollution. In order to speed up moderization and become a powerful provincial on livestock husbandry,It is suggested that Henan Province should enhance finance inputs and investment of science and technology, improve infrastructure, and promote the cycling utilization of feces and sewage and ecological cultivation technique etc.%河南是一个畜牧业大省.主要畜禽种类的生产在全国占有十分重要的地位.具有建设畜牧强省的雄厚产业基础、突出的区位优势、得天独厚的资源优势和良好的投资环境;但是河南省还不是一个畜牧强省.还存在一些制约畜牧强省建设的关键问题.包括投入严重不足、基础设施薄弱、畜禽养殖粪便污染等.建议增加投入特别是科技的投入,切实改善基础设施,大力提倡畜禽粪便循环利用及生态养殖技术,真正把畜牧业发展成为河南省现代农业的主导产业,尽快实现由畜牧业大省向强省的跨越.

  3. Issues in focus.

    Science.gov (United States)

    1994-08-01

    The issues worldwide that deserve attention pertain to international migration, the education of women, family planning, missing female children, and prevention and control of AIDS cases. Migration outside country borders has been increasing due to economic and social disparities, and uncounted and unrecognized refugees are fleeing environmental disasters. The educational status of women has increased over the past 30 years. For example, female illiteracy has declined among women aged 20-24 years from 19% to 8% in Latin America, from 38% to 12% in eastern and western Asia, and from 80% to 49% in Africa. These improvements are significant, but the problem remains, where, for instance in Africa, there is still extensive illiteracy (75% of females aged under 25 years). A 1993 Population Action International Report states that low female educational levels and weak family planning and health programs are related to large family size and high child death rates. During the 1980s family planning was linked with ecological concerns. Progress has been made in the increase in contraceptive users in developing countries from 14% to 53% during 1965-70. Fertility has declined from 6.1 children per woman in the 1950s to 3.7. Kenya is a good example of a country with high fertility that reduced fertility through its emphasis on family planning. Obstacles to increased prevalence of contraception still remain. In Mexico more than 50% of public birth control services are provided to women in secret due to fear of their husband's abuse. Population pressure can result in the loss of girl children through higher mortality, better nutrition, neglect, or gender preference in the early fetal stages. The challenge of AIDS will be in caring for the sick and adjusting to social changes due to the expected increases in orphaned children. PMID:12318864

    This paper compares trends in key economic, political and social development outcomes in the Philippines with those of Latin America, particularly since the 1990s. To do so, it uses standard indicators of development, including measures of institutional quality and good governance. The paper finds that Latin America is not only at a higher level of development, but has also made faster progress in most areas than the Philippines. This is especially the case as regards GDP per capita, poverty,...

  6. Cooperation or Security - The Emergence of Space Programs in Latin America

    Science.gov (United States)

    Godefroy, A. B.

    Traditionally, Latin America has been labeled a “Third World” region, yet when one examines its various space programs the handle hardly applies. Both Argentina and Brazil received superpower assistance during the early Cold War period to develop indigenous rocketry and space capabilities that continue to evolve today. More recently, other Latin American countries have also taken advantage of the many capabilities that space power provides. However, cooperation and development in Latin America continue to be influenced by politics and security issues, an inescapable aspect of the region's history. These factors combined have had a considerable impact on the emergence of space programs in Latin America.

    In modern discussions among health professionals there is a strange lack of discussions of power. This is most notably true for the discussions about proper physician-patient relations and the discussions about trust. This article explores some of the consequences of this absence. It is argued that the absence of the issue of power hampers a serious and open moral discussion of important institutional forms in the health care system. It is also argued that some of the proposals for how to organize physician-patient interaction are rather unrealistic, mainly because the issue of power is neglected. Finally, the article develops some ideas about how power ought to be approached in modem health care.

For most security properties, it is computational security that has to be considered: an attack scenario describes how adversaries interact with the cryptosystem, trying to attack it; the system can be called secure if adversaries with reasonably bounded computational means have negligible prospects of success. The lack of computational problems that are guaranteed to be hard in an appropriate sen...

  10. Latin America, an important new player in the great global energy game. The possibilities for an energy dialogue

    International Nuclear Information System (INIS)

    The first part of this paper deals with the latin america. Latin American energy has become a major strategic and geopolitical issue. During the last three years events in Ecuador, Bolivia and Venezuela have shown that these countries also count in the development of the world gas and oil markets. The prospects of growth in the global demand for energy during the next twenty years make one realize the shortfall between world demand and availability, in the same way that the recurrence of geopolitical crises in the regions of the world oil producers, like the Middle East, could have a destabilizing effect on international economic and political balance. Latin America will thus have a key role to play, provided that its social and political crises do not become geopolitical crises of a much more serious nature. The second part presents the possibilities of the energy dialogue. Four essential factors determine today situation in the world market: the rapid growth in the demand for energy resources in Asian countries; the increasing gap between the quantities produced and those consumed in the industrialized countries; the capacity of refining facilities and transport is already insufficient, and additional oil production possibilities are limited; and finally, the lack of openness in the world market in black gold. Efforts aimed at bringing together energy strategies and systems are a key part of the cooperation between the European Union and Russia. A similar dialogue has begun with the principal emerging powers of the Asian-Pacific Region. Our cooperation, including that within the framework of Russia presidency of the G8, will essentially be aimed at putting in place a common system of development of the key aspects of our energy policy. We are ready to act as intermediary between all the parties concerned. (authors)

  14. Domestic violence in America.

    Science.gov (United States)

    Bash, K L; Jones, F

    1994-09-01

    Domestic violence is an underrecognized problem of immense cost. It is a crime; its victims must be identified and protected. The medical and judicial communities share responsibility in addressing this issue and providing support for victims. The role of health care workers in recognizing and preventing domestic violence cannot be overestimated. Direct questioning of patients, especially about the source of any injuries and about safety at home, is the first step in uncovering abuse. Educational programs for health care providers and the general public can change society's view and tolerance of this problem. Physicians must take an active role in changing community attitudes about domestic violence and in instituting programs to reduce its incidence. Medical treatment of the injuries resulting from domestic violence is not sufficient. Abused women need the care of a team of professionals who can address psychological, emotional, and physical injuries. They must also be provided with safe housing and financial and legal assistance in order to escape the abusive relationship. Physicians and legislators must work together to effect change. Domestic violence is a public health menace. We need to break the cycle of abuse that has become an integral part of our society.
