    2009-02-01

    As with the rest of biomedicine, psychiatry has, since the Second World War, developed under the strong influence of the transnational accumulation of a whole series of practices and knowledge. Anthropology has taught us to pay attention to the transactions between local-level actors and those operating at the global level in the construction of this new world of medicine. This article examines the role played by the recommendations of the WHO Expert Committee of Mental Health in the reform of the French mental health system during the 1950s. Rooted in the experience of practitioners and administrators participating in the process of reforming local psychiatric systems, the recommendations of the WHO Expert Committee developed a new vision of regulating psychiatry, based on professionalism and an idea of a normativity of the doctor-patient relation. This article shows how, by mobilizing the WHO reports' recommendations, French administrators and doctors succeeded in creating a typically French object: "the psychiatric sector", founded on elaborating a new mandate for the psychiatric profession. The article thus questions the deinstitutionalization model as an explanation of transformations of the structure of the French psychiatry system in the post-war period.

    A naphta fraction is subjected to a catalytic reforming process in several series-connected reactors. The first reactor is equipped with a moving catalyst bed containing not more the 30% of volume of the total catalyst amount. The other reactors are designed as packed-bed systems. The content of coke deposited on the catalyst of the first reactor owing to the reforming process is maintained at below 1% of weight. This is effected by periodic removal of a proportion of the contaminated catalyst from the bottom part of the bed, by its regeneration and re-feeding to the top part of the bed. This results in prolonged service life of the catalyst and simultaneous improvement of the anti-knock value of the product.

    The ongoing healthcare reform in China has a powerful spillover effect beyond the health sector and the borders of China. A successful completion of the Chinese reform will offer a new model for social justice development, shift the global economy toward sustainability and create a new hub for science and technology in medical and health science. However, reforming the healthcare system in the most populated country is a daunting task. China will not live up to its promise, and all the potentials may end with hype not hope if coherent national strategies are not constructed and state-of-the-art navigation is not achieved with staggering domestic and global challenges. The cost of failure will be immensely high, socioeconomic costs for Chinese and an opportunity cost for the world as a whole. A full appreciation of the global implications of China's healthcare reform is crucial in keeping China receptive toward good practices evidence-approved elsewhere and open minded to fulfill its international obligations. More critically, the appreciation yields constructive engagements from global community toward a joint development and global prosperity. The current report provides a multiple disciplinary assessment on the global implications of the healthcare reform in China. Copyright © 2014 John Wiley & Sons, Ltd.

  11. Translating Globalization and Democratization into Local Policy: Educational Reform in Hong Kong and Taiwan

    Science.gov (United States)

    Law, Wing-Wah

    2004-11-01

    The past two decades have witnessed three important international trends: an increase in the number of democratic states; economic globalization; and educational reforms in light of the challenges of the new millennium. A great deal of research has addressed educational change in relation to either globalization or democratization, but little has been said about the complex interactions among all three processes. In view of recent educational reforms in Hong Kong and Taiwan, the present contribution examines the local nature of education policy in a globalized age. It challenges those globalization theories which minimize the role of the state and exaggerate the power of globalization over local factors. In particular, it explores how the governments of these two Chinese societies have employed democratization to generate and legitimate reform proposals and have used economic globalization to justify educational reforms. The study concludes by discussing the complex interrelations of these processes, including tensions between global and local concerns in educational reform.

    Full Text Available The global financial crisis that started in the U.S. had an immediate spillover to the rest of the world financial markets. Next, a decrease in real economic output throughout the developed world occurred simultaneously with high bailout costs for the salvaging of banks and other financial institutions. This vicious combination was at the core of the bank-sovereign interdependence and the sovereign debt crisis of the eurozone. As early as 2008, the G20 announced a thorough global reform agenda with an aim to tackle the root causes of the crises and to transform the system of global financial regulation. Some important reform steps have been made; still, more than six years on, the job is not finished. Where are we in terms of global financial reform, and are we close to creating a more secure global financial system significantly less prone to crisis and bailouts with taxpayers’ money?

  18. Improvements of reforming performance of a nuclear heated steam reforming process

    International Nuclear Information System (INIS)

    Hada, Kazuhiko

    1996-10-01

    Performance of an energy production process by utilizing high temperature nuclear process heat was not competitive to that by utilizing non-nuclear process heat, especially fossil-fired process heat due to its less favorable chemical reaction conditions. Less favorable conditions are because a temperature of the nuclear generated heat is around 950degC and the heat transferring fluid is the helium gas pressurized at around 4 MPa. Improvements of reforming performance of nuclear heated steam reforming process were proposed in the present report. The steam reforming process, one of hydrogen production processes, has the possibility to be industrialized as a nuclear heated process as early as expected, and technical solutions to resolve issues for coupling an HTGR with the steam reforming system are applicable to other nuclear-heated hydrogen production systems. The improvements are as follows: As for the steam reformer, (1) increase in heat input to process gas by applying a bayonet type of reformer tubes and so on, (2) increase in reforming temperature by enhancing heat transfer rate by the use of combined promoters of orifice baffles, cylindrical thermal radiation pipes and other proposal, and (3) increase in conversion rate of methane to hydrogen by optimizing chemical compositions of feed process gas. Regarding system arrangement, a steam generator and superheater are set in the helium loop as downstream coolers of the steam reformer, so as to effectively utilize the residual nuclear heat for generating feed steam. The improvements are estimated to achieve the hydrogen production rate of approximately 3800 STP-m 3 /h for the heat source of 10 MW and therefore will provide the potential competitiveness to a fossil-fired steam reforming process. Those improvements also provide the compactness of reformer tubes, giving the applicability of seamless tubes. (J.P.N.)

Special attention is given to results of cooperation of the IMF and the "Group of Twenty"in the context of the world financial crisis 2008-2009. This article mentions the key benchmarks of the historical development of world economy: foundation of the Bretton Woods financial system, rejection of the gold standard at the Jamaica Conference, transition to the floating exchange rates, the wave of crises in the 1990-s, the world financial crisis of 2008-2009. The process of evolution of the IMF within the framework of these global events is considered here. The cooperation of EU, IMF and "Group of Twenty" is considered. The reforms of the IMF and their results are analyzed. The policy of the IMF at different historical stages of its evolution is estimated. As well as it results, the article also deals with the formation and development of the "Group of Twenty". The increasing role of the "Group of Twenty" in the global economic governance and reforming the IMF is considered. Especially is marked the necessity of the further reforms of the IMF and increasing of participation of the "G-20" in the world economic and politic system.

  1. New process model proves accurate in tests on catalytic reformer

    A mathematical model has been devised to represent the process that takes place in a fixed-bed, tubular, adiabatic catalytic reforming reactor. Since its development, the model has been applied to the simulation of a commercial semiregenerative reformer. The development of mass and energy balances for this reformer led to a model that predicts both concentration and temperature profiles along the reactor. A comparison of the model's results with experimental data illustrates its accuracy at predicting product profiles. Simple steps show how the model can be applied to simulate any fixed-bed catalytic reformer.

    2014-06-05

    Addressing non-communicable diseases ("NCDs") and their risk-factors is one of the most powerful ways of improving longevity and healthy life expectancy for the foreseeable future - especially in low- and middle-income countries. This paper reviews the role of law and governance reform in that process. We highlight the need for a comprehensive approach that is grounded in the right to health and addresses three aspects: preventing NCDs and their risk factors, improving access to NCD treatments, and addressing the social impacts of illness. We highlight some of the major impediments to the passage and implementation of laws for the prevention and control of NCDs, and identify important practical steps that governments can take as they consider legal and governance reforms at country level.We review the emerging global architecture for NCDs, and emphasise the need for governance structures to harness the energy of civil society organisations and to create a global movement that influences the policy agenda at the country level. We also argue that the global monitoring framework would be more effective if it included key legal and policy indicators. The paper identifies priorities for technical legal assistance in implementing the WHO Global Action Plan for the Prevention and Control of NCDs 2013-2020. These include high-quality legal resources to assist countries to evaluate reform options, investment in legal capacity building, and global leadership to respond to the likely increase in requests by countries for technical legal assistance. We urge development agencies and other funders to recognise the need for development assistance in these areas. Throughout the paper, we point to global experience in dealing with HIV and draw out some relevant lessons for NCDs.

    Full Text Available This paper explores the connection between economic, political, and cultural globalization processes and recent education and language reforms in Colombia. Throughout the article, the author attempts to demonstrate that current education and language policies in Colombia are tightly connected to transnational agendas and models of reform that do not necessarily represent a real benefit for the majority of the population, but, instead, may render privileges for a few. With this analysis, the author insists on the need for an equitable plan for the improvement of language teaching and learning in Colombia in a way that considers local priorities of economic development, respects local knowledge and culture, and accounts for a systemic and fundamental improvement of the public system based on the dissimilar conditions that affect schools, teachers, and students in both the private and the public sectors in the country.

    2013-01-01

    Catalytic naphtha reforming process is a vital process for refineries due to the production of high-octane components, which is intensely demanded in our modern life. The significance of this industrial process induced researchers to investigate different aspects of catalytic naphtha reforming process intensively. Some of the investigators try to improve this process by representing more effective catalysts, while others try to elucidate its kinetic and deactivation mechanisms and design more efficient reactor setups. The amount of these established papers is so much that may confuse some of the researchers who want to find collective information about catalytic naphtha reforming process. In the present paper, the published studies from 1949 until now are categorized into three main groups including finding suitable catalyst, revealing appropriate kinetic and deactivation model, and suggesting efficient reactor configuration and mode of operation. These studies are reviewed separately, and a suitable reference is provided for those who want to have access to generalized information about catalytic naphtha reforming process. Finally, various suggestions for revamping the catalytic naphtha reforming process have been proposed as a guideline for further investigations

  8. Pedagogical reforms of digital signal processing education

    Science.gov (United States)

    Christensen, Michael

    The future of the engineering discipline is arguably predicated heavily upon appealing to the future generation, in all its sensibilities. The greatest burden in doing so, one might rightly believe, lies on the shoulders of the educators. In examining the causal means by which the profession arrived at such a state, one finds that the technical revolution, precipitated by global war, had, as its catalyst, institutions as expansive as the government itself to satisfy the demand for engineers, who, as a result of such an existential crisis, were taught predominantly theoretical underpinnings to address a finite purpose. By contrast, the modern engineer, having expanded upon this vision and adapted to an evolving society, is increasingly placed in the proverbial role of the worker who must don many hats: not solely a scientist, yet often an artist; not a businessperson alone, but neither financially naive; not always a representative, though frequently a collaborator. Inasmuch as change then serves as the only constancy in a global climate, therefore, the educational system - if it is to mimic the demands of the industry - is left with an inherent need for perpetual revitalization to remain relevant. This work aims to serve that end. Motivated by existing research in engineering education, an epistemological challenge is molded into the framework of the electrical engineer with emphasis on digital signal processing. In particular, it is investigated whether students are better served by a learning paradigm that tolerates and, when feasible, encourages error via a medium free of traditional adjudication. Through the creation of learning modules using the Adobe Captivate environment, a wide range of fundamental knowledge in signal processing is challenged within the confines of existing undergraduate courses. It is found that such an approach not only conforms to the research agenda outlined for the engineering educator, but also reflects an often neglected reality

  10. Globalization, statist political economy, and unsuccessful education reform in South Korea, 1993-2003.

    Directory of Open Access Journals (Sweden)

    Ki Su Kim

    2005-02-01

    Full Text Available This article examines the relationship between globalization and national education reforms, especially those of educational systems. Instead of exploring the much debated issues of how globalization affects national educational systems and how the nations react by what kinds of systemic education reform, however, it focuses on what such a method often leaves out, viz., the internal conditions of a nation that facilitates or hampers reform efforts. Taking South Korea as an example, it explores that country's unique national context which restricts and even inhibits education reforms. Especially noted here is the established "statist" political economy in education. In the paper's analysis, although South Korea's statist political economy has made a substantial contribution to economic and educational development, it is now considered increasingly unviable as globalization progresses. Nevertheless, the internal conditions, resultant from the previous statist policies, set limits on policy makers' efforts to alter the existing educational system. The analysis suggests that a fuller assessment of globalization's impact upon national educational systems or their reforms requires a perspective which is broad enough to encompass not only the concepts and/or theories of globalization and nation states but also the power relations and ideological setup of individual nations.

  13. Global Economic Governance Reform and the Roleof Asia: Opportunities Offered by the G20

    Directory of Open Access Journals (Sweden)

    Yoon Je Cho

    2012-03-01

    Full Text Available The recent global financial crisis has highlighted the importance of international monetary and financial system reform. The current system is deemed to be no longer adequate to meet the needs of a complex, integrated world economy. With regards to the reform of the international monetary system, there have been various proposals both in demand and supply sides. These include proposals to build a stronger global financial safety net, to diversify the supply of international reserve currency and so on. These proposals face trade-offs between desirability and political feasibility. Given this situation, a practical transition would be to strengthen policy coordination among the major economies and to reform the International Monetary Fund. The success on both fronts depends heavily on global economic governance reform and the role of the G20. Increased status and representation of Asian countries in the G20 give both privileges and responsibilities to Asians. To meet these responsibilities, Asians should put forth greater efforts to develop their intellectual leadership in global economic issues through creating new forum and institutions.

    Full Text Available The paper presents main trends in global economic development and impact thereof on Ukraine. A characteristic feature of the contemporary world is acceleration of globalization caused by achievements of the scientific and technological progress, which have provided technical means for successful overcoming the factors of time and space, whereby making the world more compact and ensuring the possibility of functioning as a single economic mechanism. Growing of opportunities for solving global problems is accompanied by aggravation of the latter such as: population growth, depletion of natural resources, deterioration of the environment, the mounting danger of climatic changes, potential failure to provide people with foods and potable water. Growth of social inequality in the world is also observed, as is increased differentiation of population by income level, which intensifies migration processes and thereby creates new problems related to coexistence of people belonging to different civilizations, cultures and value systems. An integral part of globalization is formation of regional associations which requires Ukraine to participate in this phase of globalization by means of becoming a member of a regional integration association with the purpose of improving its competitiveness and ensuring decent living for Ukrainian people under conditions of humanity functioning as a single planetary organism

    Fixed bed gasification is a simple and suitable technology for small scale power generation. One of the disadvantages of this technology is producing tar. So far, tar is not utilized yet and being waste that should be treated into a more useful product. This paper presents a thermodynamic analysis of tar conversion into gas producer through non-catalytic auto-thermal reforming technology. Tar was converted into components, C, H, O, N and S, and then reacted with oxidant such as mixture of air or pure oxygen. Thus, this reaction occurred auto-thermally and reached chemical equilibrium. The sensitivity analysis resulted that the most promising process performance occurred at flow rate of air was reached 43% of stoichiometry while temperature of process is 1100°C, the addition of pure oxygen is 40% and preheating of oxidant flow is 250°C. The yield of the most promising process performance between 11.15-11.17 kmol/h and cold gas efficiency was between 73.8-73.9%.The results of this study indicated that thermodynamically the conversion of tar into producer gas through non-catalytic auto-thermal reformingis more promising.

  19. Reforming Scottish Criminal Procedure: In Search of Process Values

    Directory of Open Access Journals (Sweden)

    Pamela R. Ferguson

    2017-01-01

    Full Text Available Recent proposals to reform Scottish criminal procedure are motivated by considerations of efficiency and accurate fact-finding, and there is little attempt to offer a normative account. This paper describes these proposals and contends that their emphasis on finding ‘the truth’ is misplaced on two distinct bases: (1 it equates erroneous acquittals to wrongful convictions, thus fails to uphold a fundamental tenet of criminal procedure, namely the particular importance of protecting the innocent against wrongful conviction; and (2 it fails to recognise the importance of non-instrumental process values which are at the heart of the adversarial criminal trial.  The paper suggests that it is only by adhering to these process values that the state maintains – and demonstrates that it maintains – its moral authority to condemn and punish offenders.

    Full Text Available In the article was studied the process of reforming the institute of civil service in the countries of the Eurasian space (e.g. Russia, Belarus and Kazakhstan. The integration of national systems of public administration and, in particular, the civil service, is an important factor contributing to the implementation of the centripetal tendencies in the post-Soviet space. The research methodology is based on a combination of comparative legal analysis, historical retrospective method, normalization and scaling, structural-functional and system analysis. A comparison of the legal models of public service was made in research. The author puts forward the hypothesis that it is presence the relationship between the quantitative changes (for example, number of employees of civil service and the dynamics of macroeconomic indicators (e.g. number of employed in the economy. In this regard were observed common trends. On materials of the statistical surveys were considered quantitative changes in national systems of civil service. The study of the socio-demographic characteristics of the public service (gender, age, profession allowed to formulate conclusions about the general and specific trends in the reform of the civil service of the analyzed countries. A number of values were first calculated by the author. The work is intended to become the basis for a broad international research on the development of civil service, which is the central mechanism for implementation the integration in the post-Soviet space.

    Full Text Available The international comparison and competitive focus on (academic performance, together with the growing awareness that early years impact children’s learning and development in education as well as over a lifetime, has resulted in heightened political interest in the learning of the youngest children. Politicians take action to achieve what they assume to be most effective approach, resulting in more centralized control, and more structured learning approaches introduced to children at still younger ages (Brogaard-Clausen, 2015: Brehony, 2000: Moss, 2013. In the Nordic countries1 there is a general concern for early years and the challenges facing early childhood education and care in an era of increasing globalization, with focus on accountability and academic competition (Ringsmose, Kragh-Müller, 2017. In Denmark, the social pedagogical tradition has been part of the culture of early childhood education for decades. In the social pedagogical tradition, relationships, play, and children’s influence are considered of key importance, and as the child’s natural way to learn about, and make sense of the world. It is considered that children learn and explore through play and participation embedded in the culture. Recently, the ministry of education has discussed more focused learning plans, and has tried out a program with more structured learning approaches. The gradual changes, together with the possible political action, are changes seriously threatening the social pedagogical tradition with more school-like, and more structured ways for children to interact. The purpose of this article is to present the Danish example as an alternative to the schoolification of early years that we see in many countries.

  2. Chinese Foreign Policy in a Global Perspective: A Responsible Reformer "Striving For Achievement"

    Full Text Available During the last four decades, China has moved from being an isolated country separated from the international community to having become one of the world’s major powers. It is vital to understand what is guiding Chinese foreign policy, why this is so, and not least what kind of power China is and will be in the future. This article analyses the vital elements and thinking that guides Chinese foreign policy, its priorities and decision making process. It is found that China's foreign policy is embedded in domestic issues. The foremost foreign policy objective is domestic political stability, which in turn is a necessity for the survival of one-party rule. Both are dependent on a combination of two key factors: continuing domestic economic growth and nationalism. The foreign policy is also closely linked to the Chinese self-perception, both its self-superiority/self-inferiority dualism and its multitude of confusing (overlapping identities about what China is and should be. A key turning year is 2008 when the "global" financial crisis severely affected the United States and Europe at a time of Chinese economic success, which gave China confidence to pursue a more active and aggressive/assertive stance on the international stage. It is concluded that China under Xi Jinping will not be a status que power accepting the world as it is, but nor are we to expect China to become a revisionist power aiming to remodel the global order. China is what can best be described as a responsible reformer "striving for achievements".

    Over half of American medical schools are currently engaged in significant curricular reform. Traditionally, evaluation of the efficacy of educational changes has occurred well after the implementation of curricular reform, resulting in significant time elapsed before modification of goals and content can be accomplished. We were interested in establishing a process by which a new curriculum could be reviewed and refined before its actual introduction. The University of California, San Francisco (UCSF) School of Medicine embarked upon a new curriculum for the class entering in September 2001. Two separate committees coordinated plans for curricular change. The Essential Core Steering Committee was responsible for the first two years of training, and the Integrated Clinical Steering Committee guided the development of the third-and fourth-year curriculum. Both groups operated under guidelines of curricular reform, established by the School's Committee on Curriculum and Educational Policy, that emphasized integration of basic, clinical, and social sciences; longitudinal inclusion of themes such as behavior, culture, and ethics; use of clinical cases in teaching; and inclusion of small-group and problem-based learning. In early 2001, the deans of education and curricular affairs appointed an ad hoc committee to examine the status of the first-year curriculum, which had been entirely reformulated into a series of new multidisciplinary block courses. This ad hoc committee was composed of students and clinical faculty members who had not been substantially involved in the detailed planning of the blocks. The charge to the committee was to critique the progress of individual courses, and the first year as a whole, in meeting the goals outlined above, and to make recommendations for improving the preparation of students for the clinical years. To accomplish these goals, the committee reviewed background planning documents; interviewed each course director using a

    As countries contend with an increasingly complex global environment with direct implications for population health, the international community is seeking novel mechanisms to incentivize coordinated national and international action towards shared health goals. Binding legal instruments have garnered increasing attention since the World Health Organization adopted its first convention in 2003. This paper seeks to expand the discourse on future global health lawmaking by exploring the potential value of non-binding instruments in global health governance, drawing on the case of the 2001 United Nations General Assembly Special Session Declaration of Commitment on HIV/AIDS. In other realms of international concern ranging from the environment to human rights to arms control, non-binding instruments are increasingly used as effective instruments of international cooperation. The experience of the Global AIDS Reporting Mechanism, established pursuant to the Declaration, evidences that, at times, non-binding legal instruments can offer benefits over slower, more rigid binding legal approaches to governance. The global AIDS response has demonstrated that the use of a non-binding instrument can be remarkably effective in galvanizing increasingly deep commitments, action, reporting compliance and ultimately accountability for results. Based on this case, the authors argued that non-binding instruments deserve serious consideration by the international community for the future of global health governance, including in the context of WHO reform.

    Chen, Z.; Elnashaie, S.S.E.H.

    2004-01-01

    Steam reforming of heptane for hydrogen production is investigated in a novel Circulating Fluidized Bed Membrane Reformer-Regenerator system (CFBMRR) utilizing a number of hydrogen and oxygen selective membranes. It is shown that although the amount of carbon deposition is significant, the effect on catalyst deactivation is negligible due to the large solid to gas mass feed ratio and the continuous catalyst regeneration in the system. The combustion of the deposited carbon in the catalyst regenerator supplies the heat needed for the endothermic steam reforming as well as the combustion of flammable gases from the riser reformer. Auto thermal operation is achievable for the entire adiabatic reformer-regenerator system when the exothermic heat generated from the regenerator is sufficient to compensate the endothermic heat consumed in the reformer. Multiplicity of the steady states exists in the range of steam to carbon feed ratio of 1.4442.251 mol/mol. The novel configuration has the potential advantages not only with respect to hydrogen production but also energy minimization

In this study based on the ideological origins and formation of a new direction and globalization, exploring the relationship of global and cosmic factors, the impact of the latter on the development of global processes and systems, the problem of space on the planet and escalating global processes in space. It is about the relationship of space and planetary processes, the transformation of the global response to space activities (and their interaction, and global development in the cosmic evolution. Taken as the position that global studies examining global processes and systems, and global processes are understood by the natural, social and socio-natural processes unfolding on planet Earth and have evolutionary significance. It is shown that global processes and issues affecting the world at large, is to some extent a manifestation of the global-space character of the contradictions associated with the expansion of spatial boundaries of human activity, including the conquest of space. Special attention is paid to the potential global catastrophes and geospatial software security. Considering the introduction of a substantive field cosmoglobalistiks natural processes, prospects globally exoplanet space research, as well as "global methodology" search for extraterrestrial intelligence.

    The fuel processor in which hydrogen is produced from fuels is an important unit in a fuel cell system. The aim of this study is to apply a thermodynamic concept to identify a suitable reforming process for an ethanol-fueled solid oxide fuel cell (SOFC). Three different reforming technologies, i.e., steam reforming, partial oxidation and autothermal reforming, are considered. The first and second laws of thermodynamics are employed to determine an energy demand and to describe how efficiently the energy is supplied to the reforming process. Effect of key operating parameters on the distribution of reforming products, such as H2, CO, CO2 and CH4, and the possibility of carbon formation in different ethanol reformings are examined as a function of steam-to-ethanol ratio, oxygen-to-ethanol ratio and temperatures at atmospheric pressure. Energy and exergy analysis are performed to identify the best ethanol reforming process for SOFC applications. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Richardson, Ita; Casey, Valentine; Burton, John; McCaffery, Fergal

    Our research has shown that many companies are struggling with the successful implementation of global software engineering, due to temporal, cultural and geographical distance, which causes a range of factors to come into play. For example, cultural, project managementproject management and communication difficulties continually cause problems for software engineers and project managers. While the implementation of efficient software processes can be used to improve the quality of the software product, published software process models do not cater explicitly for the recent growth in global software engineering. Our thesis is that global software engineering factors should be included in software process models to ensure their continued usefulness in global organisations. Based on extensive global software engineering research, we have developed a software process, Global Teaming, which includes specific practices and sub-practices. The purpose is to ensure that requirements for successful global software engineering are stipulated so that organisations can ensure successful implementation of global software engineering.

    Highlights: • A novel thermally coupled reactor in CCR naphtha reforming process is modeled. • The required heat of Naphtha process is attained with toluene hydrodealkylation. • A new kinetic model involving 32 pseudo-component and 84 reactions is proposed. • The aromatics and hydrogen production increase 19% and 23%, respectively. - Abstract: Due to the importance of catalytic naphtha reforming process in refineries, development of this process to attain the highest yield of desired products is crucial. In this study, continuous catalyst regeneration naphtha reforming process with radial flow is coupled with hydrodealkylation of toluene to prevent energy loss while enhancing aromatics and hydrogen yields. In this coupled process, heat is transferred between hot and cold sections (from hydrodealkylation of toluene to catalytic naphtha reforming process) using the process integration method. A steady-state two-dimensional model, which considers coke formation on the catalyst pellets, is developed and 32 pseudo-components with 84 reactions are investigated. Kinetic model utilized for HDA process is homogeneous and non-catalytic. The modeling results reveal an approximate increase of 19% and 23% in aromatics and hydrogen molar flow rates, respectively, in comparison with conventional naphtha reforming process. The improvement in aromatics production evidently indicates that HDA is a suitable process to be coupled with naphtha reforming.

  17. Power and process: The politics of electricity sector reform in Uganda

    Science.gov (United States)

    Gore, Christopher David

    In 2007, Uganda had one of the lowest levels of access to electricity in the world. Given the influence of multilateral and bilateral agencies in Uganda; the strong international reputation and domestic influence of its President; the country's historic achievements in public sector and economic reform; and the intimate connection between economic performance, social well-being and access to electricity, the problems with Uganda's electricity sector have proven deeply frustrating and, indeed, puzzling. Following increased scholarly attention to the relationship between political change, policymaking, and public sector reform in sub-Saharan Africa and the developing world generally, this thesis examines the multilevel politics of Uganda's electricity sector reform process. This study contends that explanations for Uganda's electricity sector reform problems generally, and hydroelectric dam construction efforts specifically, must move beyond technical and financial factors. Problems in this sector have also been the result of a model of reform (promoted by the World Bank) that failed adequately to account for the character of political change. Indeed, the model of reform that was promoted and implemented was risky and it was deeply antagonistic to domestic and international civil society organizations. In addition, it was presented as a linear, technical, apolitical exercise. Finally the model was inconsistent with key principles the Bank itself, and public policy literature generally, suggest are needed for success. Based on this analysis, the thesis contends that policymaking and reform must be understood as deeply political processes, which not only define access to services, but also participation in, and exclusion from, national debates. Future approaches to reform and policymaking must anticipate the complex, multilevel, non-linear character of 'second-generation' policy issues like electricity, and the political and institutional capacity needed to increase

    Some commentators view my analyses (Clark, 2012, this issue) as an important step forward in assessing the costs and benefits of eyewitness identification reform. Others suggest that the trade-off between correct identifications lost and false identifications avoided is well-known; that the expected utility model is misspecified; and that the loss of correct identifications due to the use of reformed eyewitness identification procedures is irrelevant to policy decisions, as those correct identifications are the illegitimate product of suggestion and lucky guesses. Contrary to these criticisms, the loss of correct identifications has not been adequately considered in theoretical or policy matters, criticisms regarding the various utilities do not substantively change the nature of the trade-off, and the dismissal of lost correct identifications is based not on data but on an outdated theory of recognition memory. © The Author(s) 2012.

    2017-01-01

    Highlights: • The effect of O_2 content from 0 to 15% on Ni/SiO_2 are studied for biogas reforming. • The presence of O_2 in biogas improves CH_4 conversion and stability of biogas reforming. • An obvious carbon-resistance effect is observed due to the carbon gasification effect of O_2 in biogas. • The presence of O_2 in biogas greatly helps inhibit the catalyst sintering. - Abstract: We report an energy-efficient biogas reforming process with high and stable methane conversions by O_2 presence. During this biogas reforming process, the effects of various O_2 concentrations in biogas on initial conversions and stability at various temperatures on a Ni/SiO_2 catalyst were detailed investigated. In addition, theoretical energy consumption and conversions were calculated based on the Gibbs energy minimization method to compare with experimental results. Carbon formation and sintering during the reforming process were characterized by thermal gravity analysis, the Brunauer-Emmett-Teller method, X-ray diffraction, and high-resolution transmission electron microscopy to investigate the feasibility of applying this process to an inexpensive nickel catalyst. The results showed that 5% O_2 in biogas improved the CH_4 conversion and stability of biogas reforming. The enhancement of stability was attributed to the inhibited sintering, our first finding, and the reduced carbon deposition at the same time, which sustained a stable conversion of CH_4, and proved the applicability of base Ni catalyst to this process. Higher O_2 concentrations (⩾10%) in biogas resulted in severe decrease in CO_2 conversion and greater H_2O productivity. Our proposed biogas reforming process, with a high and stable conversion of CH_4, reduced energy input, and the applicability to inexpensive base metal catalyst, offers a good choice for biogas reforming with low O_2 concentrations (⩽5%) to produce syngas with high energy efficiency.

    Directory of Open Access Journals (Sweden)

    Jürgen Beyer

    2012-12-01

    Full Text Available Thus far, the sequencing of political reform processes has been discussed on a separate basis in the context of different scientific debates. Existing analysis in macroeconomics and democracy theory focuses on shock-therapeutic versus gradual reform policies, the succession of specific reform steps or the right timing of reforms. An analytical approach to sequences has been elaborated. Theoretical concepts of social change, which refer to path dependence or the punctuated development of historical sequences, have evolved in the context of institutionalist research. The present article summarises the state of research and extends it with conceptual reflections on the motivation of sequential political action, which can then serve as a starting point for differentiation between sequencing processes in further research.

    For improved sustainability of the biorefinery industry, biorefinery-byproduct glycerol is being investigated as an alternate source for hydrogen production. This research designs and optimizes a hydrogen-production process for small hydrogen stations using steam reforming of purified glycerol as the main reaction, replacing existing processes relying on steam methane reforming. Modeling, simulation and optimization using a commercial process simulator are performed for the proposed hydrogen production process from glycerol. The mixture of glycerol and steam are used for making syngas in the reforming process. Then hydrogen are produced from carbon monoxide and steam through the water-gas shift reaction. Finally, hydrogen is separated from carbon dioxide using PSA. This study shows higher yield than former U.S.. DOE and Linde studies. Economic evaluations are performed for optimal planning of constructing domestic hydrogen energy infrastructure based on the proposed glycerol-based hydrogen station

    2010-01-01

    Full text: The aim of this work has been undertaken as part of the design of continuous hydrogen production using the high temperature steam reforming process. The steady-state test condition was carried out using syngas from biomass pyrolysis, whilst operating at high temperatures between 600 and 1200 degree Celsius. The main reformer operating parameters (e.g. temperature, resident time and steam to biomass ratio (S/B)) have been examined in order to optimize the performance of the reformer. The operating temperature is a key factor in determining the extent to which hydrogen production is increased at higher temperatures (900 -1200 degree Celsius) whilst maintaining the same as resident time and S/B ratio. The effects of exhaust gas composition on heating value were also investigated. The steam reforming process produced methane (CH 4 ) and ethylene (C 2 H 4 ) between 600 to 800 degree Celsius and enhanced production ethane (C 2 H 6 ) at 700 degree Celsius. However carbon monoxide (CO) emission was slightly increased for higher temperatures all conditions. The results show that the use of biomass pyrolysis gas can produce higher hydrogen production from high temperature steam reforming. In addition the increasing reformer efficiency needs to be optimized for different operating conditions. (author)

    Nickel-based catalysts are often used to reform methanol into hydrogen. The preparation and installation of these catalysts are costly and laborious. As an alternative, directly applying catalytic films onto the separator components can improve the manufacturing efficiency. This paper reports the successful deposition of adherent porous NiO-Al 2 O 3 -based catalytic films with well-controlled stoichiometry, using a single-step Aerosol Assisted Chemical Vapour Deposition (AACVD) method. The microstructure, composition and crystalline phase of the as-deposited catalytic films are characterized using a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared (FTIR) Spectrometer. The results have demonstrated the capability of AACVD to produce porous NiO-Al 2 O 3 -based catalytic films

    Medeiros, Regianne Leila Rolim; Atkinson, Sarah

    2015-01-01

    The objective of this article is to offer an overview of the health reform in Ceará focusing on the decentralisation process in the 1990s. The driving factor behind the Brazilian health reform movement was the necessity to reorganise the national health system and overcome inequalities. For the reformists, decentralisation, and together with it the idea of popular participation, is seen as essential to guarantee the fulfilment of the people’s needs and to incorporate their voice in the decision-making processes of the health system. In the state of Ceará, after the 1986 elections, health reform movement members took control over the management of the state Health Secretariat. This is the main cause of the acceleration of the decentralisation process with the transference of responsibility over the management of health care delivery to municipalities. PMID:25729333

During 2004- 2009, within the reform process, the main actors involved in the coordination, implementation and monitoring of reform measures were: the Prime Minister, the Superior Council for Public Administration Reform, Public Policy Coordination and Structural Adjustment, the Ministry of Public Finance, the General Secretariat of Government, Ministry of Administration and Interior (renamed for a short time Ministry of Interior and Administrative Reform, the Central Unit for Public Administration Reform, National Institute of Administration, the National Agency of Civil Servants, and the National Modernizers Network. For evaluation of aspects related to the reform process it was designed a selective research within the members of the National Modernizers Network, for assessing their perception of the public administration reform undertaken by the institutions presented above. Evaluating their opinion can be an important point in the revitalization of the area of the administration reform process. Also, the research conducted aimed at assessing the degree of modernizers’ involvement in activities related to important aspects of the reform process: strategic planning, formulating and evaluating public policies, financial management, human resources management, decentralization, introduction of new information and communication technologies and administrative simplification.

    Hydrogen is mainly employed like primary product, for the synthesis of ammonia. The ammonia is synthesized by chemically combining hydrogen and nitrogen under pressure, in the presence of a catalyst. This ammonia is used, for the production of the nitrate fertilizers. Nowadays hydrogen gains more attention mainly because, it is regarded as a future significant fuel by much of experts. The widespread use of hydrogen as source of energy could help to reduce the concern concerning the safety of energy, the total change of climate and the quality of air. Hydrogen is presented then as an excellent alternate initially and as substitute thereafter. It can play a role even more significant than conventional energies. Indeed, it has the advantage of being nonpolluting and it can use the same means of transport as conventional energies. For Algeria, it proves of importance capital. It not only makes it possible to increase and diversify its energy reserves and its exports but also to provide for its energy needs which become increasingly significant. Although hydrogen can be produced starting from a large variety of resources using a range of various technologies, the natural gas is generally preferred and will remain in the near future the principal primary product for the manufacture of hydrogen. Currently the most effective means of production of hydrogen is the Steam Reforming of Natural Gas (SMR). This process is seen as a one of principal technologies for the production of hydrogen. The disadvantages of this process it's that it consumes a great quantity of primary energy and that it releases in the atmosphere the gases that contribute to the warming of the plane. Among the alternatives processes of hydrogen production one can quote solar thermochemical processes. In this study, an exergetic analysis of the process of hydrogen production based on Zn/ZnO redox reactions is presented. In the first part of this study, an exergetic analysis is made for a temperature of the

    Producing energy from biomass and other organic waste residues is essential for sustainable development. Fraunhofer UMSICHT has developed a novel reactor which introduces the Thermo-Catalytic Reforming (TCR®) process. The TCR® is a process which can convert any type of biomass and organic feedstocks into a variety of energy products (char, bio-oil and permanent gases). The aim of this work was to demonstrate this technology using digestate as the feedstock and to quantify the results from the post reforming step. The temperature of a post reformer was varied to achieve optimised fuel products. The hydrogen rich permanent gases produced were maximised at a post reforming temperature of 1023 K. The highly de-oxygenated liquid bio-oil produced contained a calorific value of 35.2 MJ/kg, with significantly improved fuel physical properties, low viscosity and acid number. Overall digestate showed a high potential as feedstock in the Thermo-Catalytic Reforming to produce pyrolysis fuel products of superior quality. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available What is the relation between globalization and the process of European integration? Does the European integration have its own way, or is it deeply dependent on globalization? Those are the main questions I will try to answer in this paper by using an alternative critical approach: neo-gramscianism. Neo-gramscianism is a historical materialist view on the European integration process and international political economy which offers a better understanding of the social changes in terms of social forces agency and super structural influence (the neoliberal ideology of globalization and European integration. My aim is to analyze the globalization process through a neo-gramscian theoretical framework and to observe how its main components affect European Integration. I will do this by assuming the definition of globalization provided by Andreas Bieler, who understands this process through three main pillars: transnationalization of finance, transnationalization of production and ideological shift from Keynesianism to neoliberalism. Finally I will try to formulate some conclusions regarding the emergence of European Round Table of Industrialists – the first lobby group of big capital at the European Union level – and Economic and Monetary Union – the internal market program that symbolizes the shift to neo-liberalism.

  15. Reformed and reforming: Adapting the licensing process to meet new challenges

    2017-01-01

    The NRC has engaged in a steady, albeit modest, examination of its preparedness for advanced designs over the past few years. These efforts have included examination of its own guidance and processes as well as co-operation with the US Department of Energy (US DOE) in identifying key issues and potential strategies. But the NRC is constrained in some respects from devoting substantial resources to the development of new or revised regulatory approaches due to statutory requirements that the NRC recover most of its appropriated funds through user fees imposed on the industry. Unless designers are prepared to put up the funds necessary to cover the fees for review of the new designs, the NRC is not able to review them, and licensees of operating facilities paying annual fees may not all be supportive of the NRC expending resources to develop infrastructure for the review of advanced reactor designs. Given the current context, this article will attempt to reflect on the NRC's current framework for licensing, the lessons from NRC's regulations in 10 CFR Part 52 and strategies for adapting to the new demands that may be made on the agency

    Full Text Available Proceeding from the changes in direct and indirect taxation in the process of the EU tax system reform and the fact that new trends bring about vital social changes, the research in this area could add to the understanding of economic development of these countries. In the EU with its decentralized tax policy, changes in direct and indirect taxation are permanently implemented in the process of tax system reform. Harmonization of direct and indirect taxation in the EU is conducted by means of the adopted community law regulations. In the harmonization of direct taxation there is a tendency towards an increase of the level of fiscal coordination and elimination of barriers to the common market. Thus direct taxation reforms are limited to achieving higher level of coordination and preventing evasion and double taxation. The current policy is the result of the principle according to which fiscal competition has positive effects on reducing consumption and on the EU economic development. In the harmonization process the systems of indirect taxation are aligned particularly with excise duty and value added tax. Fiscal strategies in the reform process are mostly aimed at fiscal coordination, modernization, informative cooperation, evasion reduction and elimination of malpractices in fulfilling a VAT payment liability. Within the excise tax system minimal excise rates are determined and an environmentally-friendly policy is pursued. The main priorities of taxation changes within the harmonization process are in respect of evasion reduction and irrational fiscal competition on the EU market. A study of direct and indirect taxation changes in the process of the tax system reform is highly significant both from the aspect of efficient tax-system functioning, which results in achieving EU macroeconomic goals, and from the aspect of single states' interests in the process of transition and accession.

The globalization process of the financial markets affected also the Romanian market even before Romania became member of the European Union. The globalization brought about benefits (especially under the form of increase in the quality of the services provided to clients but also disadvantages for local companies (significant costs in logistics and training in order to cope with the international groups.

  18. A numerical analysis of heat and mass transfer during the steam reforming process of ethane

    2017-11-01

    This paper presents a numerical analysis of heat and mass transfer during the steam reforming of ethane. From a chemical point of view, the reforming process of heavy hydrocarbons, such as ethane, is complex. One of the main issue is a set of undesired chemical reactions that causes the deposition of solid carbon and consequently blocks the catalytic property of a reactor. In the literature a carbon deposition regime is selected by thermodynamical analysis to design safe operation conditions. In the case of Computational Fluid Dynamic (CFD, hereafter) models each control volume should be investigated to determinate if carbon deposition is thermodynamically favourable. In this paper the authors combine equilibrium and kinetics analysis to simulate the steam reforming of methane-ethane rich fuel. The results of the computations were juxtaposed with experimental data for methane steam reforming, and good agreement was found. An analysis based on the kinetics of reactions was conducted to predict the influence of temperature drop and non-equilibrium composition on solid carbon deposition. It was found that strong non-uniform temperature distribution in the reactor causes conditions favourable for carbon deposition at the inlet of the reformer. It was shown that equilibrium calculations, often used in the literature, are insufficient.

  19. Developing an energy efficient steam reforming process to produce hydrogen from sulfur-containing fuels

    Science.gov (United States)

    Simson, Amanda

    Hydrogen powered fuel cells have the potential to produce electricity with higher efficiency and lower emissions than conventional combustion technology. In order to realize the benefits of a hydrogen fuel cell an efficient method to produce hydrogen is needed. Currently, over 90% of hydrogen is produced from the steam reforming of natural gas. However, for many applications including fuel cell vehicles, the use of a liquid fuel rather than natural gas is desirable. This work investigates the feasibility of producing hydrogen efficiently by steam reforming E85 (85% ethanol/15% gasoline), a commercially available sulfur-containing transportation fuel. A Rh-Pt/SiO2-ZrO2 catalyst has demonstrated good activity for the E85 steam reforming reaction. An industrial steam reforming process is often run less efficiently, with more water and at higher temperatures, in order to prevent catalyst deactivation. Therefore, it is desirable to develop a process that can operate without catalyst deactivation at more energy efficient conditions. In this study, the steam reforming of a sulfur-containing fuel (E85) was studied at near stoichiometric steam/carbon ratios and at 650C, conditions at which catalyst deactivation is normally measured. At these conditions the catalyst was found to be stable steam reforming a sulfur-free E85. However, the addition of low concentrations of sulfur significantly deactivated the catalyst. The presence of sulfur in the fuel caused catalyst deactivation by promoting ethylene which generates surface carbon species (coke) that mask catalytic sites. The amount of coke increased during time on stream and became increasingly graphitic. However, the deactivation due to both sulfur adsorption and coke formation was reversible with air treatment at 650°C. However, regenerations were found to reduce the catalyst life. Air regenerations produce exotherms on the catalyst surface that cause structural changes to the catalyst. During regenerations the

  5. FLUIDIZED BED STEAM REFORMING MINERALIZATION FOR HIGH ORGANIC AND NITRATE WASTE STREAMS FOR THE GLOBAL NUCLEAR ENERGY PARTNERSHIP

    Energy Technology Data Exchange (ETDEWEB)

    Jantzen, C; Michael Williams, M

    2008-01-11

    Waste streams that may be generated by the Global Nuclear Energy Partnership (GNEP) Advanced Energy Initiative may contain significant quantities of organics (0-53 wt%) and/or nitrates (0-56 wt%). Decomposition of high nitrate streams requires reducing conditions, e.g. organic additives such as sugar or coal, to reduce the NO{sub x} in the off-gas to N{sub 2} to meet the Clean Air Act (CAA) standards during processing. Thus, organics will be present during waste form stabilization regardless of which GNEP processes are chosen, e.g. organics in the feed or organics for nitrate destruction. High organic containing wastes cannot be stabilized with the existing HLW Best Developed Available Technology (BDAT) which is HLW vitrification (HLVIT) unless the organics are removed by preprocessing. Alternative waste stabilization processes such as Fluidized Bed Steam Reforming (FBSR) operate at moderate temperatures (650-750 C) compared to vitrification (1150-1300 C). FBSR converts organics to CAA compliant gases, creates no secondary liquid waste streams, and creates a stable mineral waste form that is as durable as glass. For application to the high Cs-137 and Sr-90 containing GNEP waste streams a single phase mineralized Cs-mica phase was made by co-reacting illite clay and GNEP simulated waste. The Cs-mica accommodates up to 30% wt% Cs{sub 2}O and all the GNEP waste species, Ba, Sr, Rb including the Cs-137 transmutation to Ba-137. For reference, the cesium mineral pollucite (CsAlSi{sub 2}O{sub 6}), currently being studied for GNEP applications, can only be fabricated at {ge} 1000 C. Pollucite mineralization creates secondary aqueous waste streams and NO{sub x}. Pollucite is not tolerant of high concentrations of Ba, Sr or Rb and forces the divalent species into different mineral host phases. The pollucite can accommodate up to 33% wt% Cs{sub 2}O.

    Full Text Available Romanian society is in a continuous process of change in which all the economic, social, political, civic saw a new dynamic in trying to adapt to specific conditions of the phenomenon of Europeanization (full member of the European Union. The changing of Romanian society requires the public administration reform to be analyzed and disseminated on the following levels: strategic - by which to redefine the role of the state clearly, legally - using larger framework laws, organizational - administrative and fiscal decentralization, cultural - following a change of values and modes of action of public officials, non governmental organizations, the citizen / customer of public service. The term administrative reform is trivial, repetitive and recurrent nets into change, public administration reform is invited to constantly readjust the organization and the action and to clearly state objectives, called sometimes the brakes released, blockages to overcome obstacles of the past which is manifested by the upward trend of the society. Public administration is criticized especially by the public and less by governments in office. Almost general belief is that the administration functions poorly, fulfil its mission in an unsatisfactory manner, but nevertheless has an impact too on community life, economy and society. This paper aims to identify the type of problems that other countries have had to solve and the need hierarchy and management combined in a single system. Understanding the types of problems encountered and they do other countries in this process will shorten the learning cycle for Romania. The objectives of this approach is that the critical analysis of the relationship between public administration reform and administrative capacity based on the literature, outlining the operational model to assess the reform process in our country, the study of democratization (the stage of democratization of public administration modernization strategy

    Full Text Available This paper reviews and assesses the chances for survival and development of the media in Serbia and ib the region, from the perspective of new information and communication technologies (ICT applied in media business. In the paper theoretical method is used and harmonized with the needs of describing the problems and the observed processes and phenomena, as well as empirical method which is used for collecting and interpreting concrete facts and data on the observed processes and phenomena. The starting point lies in the fact that modern media is definitely, more and more, dependent on new technologies. A part of the new technologies is used in the process of collecting, selecting and editing media content, while the other part of the technology is used in the process of dissemination and propulsion of media content to the mass audience, and also in the feedback function as well. The technology revolution, which we describe, started with mp3, jpg and avi files, and continues with internet broadcasting, social networks, cloud technologies and new digital platforms which are used by today's media for distribution of media content. The particularity of the media in the region lies in the fact that they operating in the societes with delay of political and economic transition, so all the productive resources of society, due to this backlog, are slower adapted to the new conditions of business in the digital era. The consequences that have arisen from such dynamics of development make many media in Serbia and the region quite dysfunctional, especially those who were exposed during this transition to long-standing legal, economic and program crises. That is why most of the existing media in Serbia, especially small ones, are unprepared for modernization and they are not ready for re-modeling in accordance with the new technological circumstances.

  9. Spherical Process Models for Global Spatial Statistics

    KAUST Repository

    Jeong, Jaehong

    2017-11-28

    Statistical models used in geophysical, environmental, and climate science applications must reflect the curvature of the spatial domain in global data. Over the past few decades, statisticians have developed covariance models that capture the spatial and temporal behavior of these global data sets. Though the geodesic distance is the most natural metric for measuring distance on the surface of a sphere, mathematical limitations have compelled statisticians to use the chordal distance to compute the covariance matrix in many applications instead, which may cause physically unrealistic distortions. Therefore, covariance functions directly defined on a sphere using the geodesic distance are needed. We discuss the issues that arise when dealing with spherical data sets on a global scale and provide references to recent literature. We review the current approaches to building process models on spheres, including the differential operator, the stochastic partial differential equation, the kernel convolution, and the deformation approaches. We illustrate realizations obtained from Gaussian processes with different covariance structures and the use of isotropic and nonstationary covariance models through deformations and geographical indicators for global surface temperature data. To assess the suitability of each method, we compare their log-likelihood values and prediction scores, and we end with a discussion of related research problems.

Purpose: We wanted to determine how the old member States EU (15 and the new EU member states adapt to the new circumstances and other changes in the micro and macro environment. Method: Analysing complexity of the changes of the state of economic system, and complex fundamental global processes, which have been occurred in long period of time, need to supplement the pure scientific approach with other types of research work, more holistic approach, which is commonly used in Comparative economics. We have taken such an approach in this article. Results: In the article we studied the geopolitical changes in the micro and macro environment. We found that the development in the old EU member states EU-15 and in the new EU member states is different. EU havent addopted the harmonised economic policy which will solve the »North-South« problem and cross-state cultural consensus and find a way to operate systemically in global environment. Organization: The findings can be used to support undestanding of micro and macro envirnment of the companys and contribute for better strategic planning and design of the entire supply chain. Society: The findings can contribute to better understanding of integrative processes in the EU. Limitations/Future Research: The complexity of the problem and the dynamic changes in the functioning of the global market requires in-depth studiying of changes in the micro and macro environment of logistics companie

    What does an individual with autism spectrum disorder (ASD) perceive first: the forest or the trees? In spite of 30 years of research and influential theories like the weak central coherence (WCC) theory and the enhanced perceptual functioning (EPF) account, the interplay of local and global visual processing in ASD remains only partly understood. Research findings vary in indicating a local processing bias or a global processing deficit, and often contradict each other. We have applied a formal meta-analytic approach and combined 56 articles that tested about 1,000 ASD participants and used a wide range of stimuli and tasks to investigate local and global visual processing in ASD. Overall, results show no enhanced local visual processing nor a deficit in global visual processing. Detailed analysis reveals a difference in the temporal pattern of the local-global balance, that is, slow global processing in individuals with ASD. Whereas task-dependent interaction effects are obtained, gender, age, and IQ of either participant groups seem to have no direct influence on performance. Based on the overview of the literature, suggestions are made for future research. (c) 2015 APA, all rights reserved).

  12. The 2014 Global Tax Competitiveness Report: A Proposed Business Tax Reform Agenda

    Directory of Open Access Journals (Sweden)

    Duanjie Chen

    2015-02-01

    Full Text Available Canada is losing its edge in the competition for global capital. After a decade of remarkable progress in reducing the tax burden on business investment — moving from one of the least tax-competitive jurisdictions among its industrialized peers in 2000, to ranking in the middle of the pack by 2011 — Canada has slipped by largely standing still. As other countries in our peer group have continued to reform their business-tax regimes, they have surpassed Canada, which has slid from having the 19th-highest tax burden on investments by medium-sized and large corporations in 2012, to the 14th-highest among 34 OECD countries in 2014. Even more worrying is that Canada’s political currents are running the wrong way, with a few provinces having increased taxes on capital in recent years and a number of politicians today floating the possibility of even higher business taxes to help address budgetary strains. But the right approach to raising tax revenue and improving the economy is quite the opposite: lowering rates and broadening the tax base by making Canadian jurisdictions even more attractive to corporate investment. An important step towards that would be for federal and provincial governments to reduce targeted tax assistance and to level the tax field for all industries and sizes of businesses, ending the preferential treatment of favoured industries and small enterprises. In addition, those provinces that have yet to harmonize their sales tax with the federal GST should do so, or at least consider adopting a quasi-refund system that would relieve the provincial sales tax on capital inputs. Alberta, with no sales tax, could become more competitive by adopting an HST and using the proceeds to reduce personal and corporate taxes. Finally, Canada would do much better to mandate a uniform corporate tax rate, with an 11 per cent federal rate and a nine per cent average provincial rate. This would encourage capital investment and attract corporate

    In the construction of reactors or pressure vessels for oil chemical plants and nuclear power stations, mono block open-die forging rings are often utilized. Generally, a large forged ring is manufactured by means of enlarging forging with reductions of the wall thickness. During the enlarging process the circular ring is often distorted and becomes an ellipse in shape. However the shape control of the ring is a complicated work. This phenomenon makes the matter still worse in forging of larger rings. In order to make precision forging of large rings, we have developed the forging method using a v-shape anvil. The v-shape anvil is geometrically adjusted to fit the distorted ring in the final circle and reform automatically the shape of the ring during enlarging forging. This paper has analyzed the reforming process of distorted ring by computer program based on F.E.M. and examined the effect on the precision of ring forging. (author)

    Curriculum reform in medical schools continues to be an ever-present and challenging activity in medical education. This paper describes one school's experiences with specific curricular innovations that were developed or adapted and targeted to meet a clear set of curricular goals during the curriculum reform process. Those goals included: (a) promoting active learning and learner engagement; (b) establishing early professional identity; and (c) developing physician competencies in an integrated and contextual manner while allowing for individualized learning experiences for the millennial student. Six specific innovations championed by the school are described in detail. These included Themes in Medical Education, Translational Pillars, Stony Brook Teaching Families, Transition Courses, Educational Continuous Quality Improvement Processes, and our Career Advising Program. Development of the ideas and design of the innovations were done by faculty and student teams. We discuss successes and ongoing challenges with these innovations which are currently in the fourth year of implementation. Our curriculum reform has emphasized the iterative process of curriculum building. Based on our experience, we discuss general and practical guidelines for curriculum innovation in its three phases: setting the stage, implementation, and monitoring for the achievement of intended goals.

    Along with the economic development, needs of energy being increase too. Hydrogen as alternative energy has many usages. Besides that, hydrogen is one source of energy that is a clean fuel, but process production of hydrogen from natural gas as a raw material has been used for a long time. Therefore, there is need new invention to produce hydrogen from the others raw material. Glycerol, a byproduct of biodiesel production, is a compound which can be used as a raw material for hydrogen production. By using glycerol as a raw material of hydrogen production, we can get added value of glycerol as well as an energy source solution. The process production of hydrogen by steam reforming is a thermochemical process with efficiency 70%. This process needs contribution of catalyst to improve its efficiency and selectivity of the process. In this study will be examined the effect variation of catalyst for glycerol conversion process to hydrogen by steam reforming. The method for catalyst preparation was variation of catalyst impregnation composition, catalyst calcined with difference concentration of hydrochloric acid and calcined with difference hydrochloric acid ratio. After that, all of catalyst which have been prepared, used for steam reforming process for hydrogen production from glycerol as a raw material. From the study, the highest yield of hydrogen gas showed in the process production by natural zeolite catalyst with 1:15 Hydrochloric acid ratio was 42.28%. Hydrogen yield for 2M calcined natural zeolite catalyst was 38.37%, for ZSM-5 catalyst was 15.83%, for 0.5M calcined natural zeolite was 13.09% and for ultrasonic natural zeolite was 11.43%. The lowest yield of hydrogen gas showed in catalyst 2Zn/ZSM-5 with 11.22%. This result showed that hydrogen yield product was affected by catalyst variation because of the catalyst has difference characteristic and difference catalytic activity after the catalyst preparation process.

    Full Text Available The growing surplus of green electricity generated by renewable energy technologies has fueled research towards chemical industry electrification. By adapting power-to-chemical concepts, such as plasma-assisted processes, cheap resources could be converted into fuels and base chemicals. However, the feasibility of those electrified processes at large scale has not been investigated yet. Thus, the current work strives to compare, for first time in the literature, plasma-assisted production of syngas, from CH4 and CO2 (dry methane reforming, with thermal catalytic dry methane reforming. Specifically, both processes are conceptually designed to deliver syngas suitable for methanol synthesis (H2/CO ≥ 2 in mole. The processes are simulated in the Aspen Plus process simulator where different process steps are investigated. Heat integration and equipment cost estimation are performed for the most promising process flow diagrams. Collectively, plasma-assisted dry methane reforming integrated with combined steam/CO2 methane reforming is an effective way to deliver syngas for methanol production. It is more sustainable than combined thermal catalytic dry methane reforming with steam methane reforming, which has also been proposed for syngas production of H2/CO ≥ 2; in the former process, 40% more CO2 is captured, while 38% less H2O is consumed per mol of syngas. Furthermore, the plasma-assisted process is less complex than the thermal catalytic one; it requires higher amount of utilities, but comparable capital investment.

  19. Global Precipitation Responses to Land Hydrological Processes

    2012-12-01

    Several studies have established that soil moisture increases after adding a groundwater component in land surface models due to the additional supply of subsurface water. However, impacts of groundwater on the spatial-temporal variability of precipitation have received little attention. Through the coupled groundwater-land-atmosphere model (NCAR Community Atmosphere Model + Community Land Model) simulations, this study explores how groundwater representation in the model alters the precipitation spatiotemporal distributions. Results indicate that the effect of groundwater on the amount of precipitation is not globally homogeneous. Lower tropospheric water vapor increases due to the presence of groundwater in the model. The increased water vapor destabilizes the atmosphere and enhances the vertical upward velocity and precipitation in tropical convective regions. Precipitation, therefore, is inhibited in the descending branch of convection. As a result, an asymmetric dipole is produced over tropical land regions along the equator during the summer. This is analogous to the "rich-get-richer" mechanism proposed by previous studies. Moreover, groundwater also increased short-term (seasonal) and long-term (interannual) memory of precipitation for some regions with suitable groundwater table depth and found to be a function of water table depth. Based on the spatial distributions of the one-month-lag autocorrelation coefficients as well as Hurst coefficients, air-land interaction can occur from short (several months) to long (several years) time scales. This study indicates the importance of land hydrological processes in the climate system and the necessity of including the subsurface processes in the global climate models.

  20. Reform of abortion law in Uruguay: context, process and lessons learned.

    In October 2012, a new law was approved in Uruguay that allows abortion on demand during the first 12 weeks of pregnancy, 14 weeks in the case of rape, and without a time limit when the woman's health is at risk or in the case of foetal anomalies. This paper analyses this legal reform. It is based on 27 individual and group interviews with key informants, and on review of primary documents and the literature. The factors explaining the reform include: secular values in society, favourable public opinion, a persistent feminist movement, effective coalition building, particular party politics, and a vocal public health sector. The content of the new law reflects the tensions between a feminist perspective of women's rights and public health arguments that stop short of fully recognizing women's autonomy. The Uruguayan reform shows that, even in Latin America, abortion can be addressed politically without electoral cost to the parties that promote it. On the other hand, the prevailing public health rationale and conditionalities built into the law during the negotiation process resulted in a law that cannot be interpreted as a full recognition of women's rights, but rather as a modified protectionist approach that circumscribes women's autonomy.

  1. How to understand, evaluate and influence efficient progress in South Africa’s land reform process: A typology from historical lessons from selected sub-Saharan African countries

    Directory of Open Access Journals (Sweden)

    Nhlanhla C. Mbatha

    2017-12-01

    Full Text Available Background: With reports of widespread failures in South Africa’s land reform programmes, the levels of policy uncertainty in the political rhetoric that influences land reform have been increasing. Since 1994 policy targets to transfer land to black farmers have not been met. Of the 2005 target to transfer about 25 million ha of commercial farmland to black farmers by 2014, less than 5 million ha. have been transferred for commercial use. Some studies report failure rates in resettlement projects of up to 90%. To account for the failures, revisions of policies and amendments to legislations have been proposed within a political environment that is becoming increasingly intolerant to slow progress in land transfers and to resettlement failures. Aim: Against this environment, this paper presents a typology for understanding and evaluating important elements of the land reform project in order to influence progress in the process. Setting: The study adopts a historical review of land reform processes in post-colonial Kenya and Zimbabwe in order to identify potential challenges and key lessons for South Africa. Methods: Hence, using institutional and historical analytical lenses in exploring different narratives, the paper reviews reported failures and successes in land reform policy cases from the selected countries. From an institutional framework, prevalent social institutions and key lessons from Kenya, Zimbabwe and South Africa, a typology for evaluating important elements of the land reform process in South Africa is developed and discussed. Additionally, a review of global data collected on average sizes of farms in different regions of the world is provided as evidence to support propositions of what would constitute efficient farmland size ranges for small to medium commercial farms in South Africa. Results and conclusion: A proposition is made on how to use the typology to guide policy and research interventions to reduce failures

    The present optimization investigation is classified into reforming configuration optimization in one hand and parameter optimization of each configuration on the other hand. Heptane is used as a model component for heavy hydrocarbons. The proposed novel reforming process is basically a Circulating Fluidized-Bed Membrane Reformer (CFBMR) with continuous catalyst regeneration and gas-solid separation. Composite hydrogen selective membranes are used for removing the product hydrogen from the reacting gas mixture and therefore driving the reversible reactions beyond their thermodynamic equilibriums. Dense perovskite oxygen selective membranes are also used to introduce oxygen for the exothermic oxidation of hydrocarbons and carbon. Four configurations are investigated, two of them are with the catalyst regeneration before the gas-solid separation and the other two are with the catalyst regeneration after the gas-solid separation. The optimization of the performance of each configuration is carried out for a number of design and operating parameters as optimization parameters and under both non-autothermal and autothermal reforming conditions. Results show that the autothermal operation with direct contact between cold feeds (water and heptane) and hot circulating catalyst can be the best configuration for efficient hydrogen production with minimum energy consumption. The maximum net hydrogen yield is 16.732 moles of hydrogen per mole of heptane fed, which is 76.05% of the maximum theoretical hydrogen yield of 22. (author)

  3. Global simulations of aerosol processing in clouds

    2008-12-01

    Full Text Available An explicit and detailed representation of in-droplet and in-crystal aerosol particles in stratiform clouds has been introduced in the global aerosol-climate model ECHAM5-HAM. The new scheme allows an evaluation of the cloud cycling of aerosols and an estimation of the relative contributions of nucleation and collision scavenging, as opposed to evaporation of hydrometeors in the global aerosol processing by clouds. On average an aerosol particle is cycled through stratiform clouds 0.5 times. The new scheme leads to important changes in the simulated fraction of aerosol scavenged in clouds, and consequently in the aerosol wet deposition. In general, less aerosol is scavenged into clouds with the new prognostic treatment than what is prescribed in standard ECHAM5-HAM. Aerosol concentrations, size distributions, scavenged fractions and cloud droplet concentrations are evaluated and compared to different observations. While the scavenged fraction and the aerosol number concentrations in the marine boundary layer are well represented in the new model, aerosol optical thickness, cloud droplet number concentrations in the marine boundary layer and the aerosol volume in the accumulation and coarse modes over the oceans are overestimated. Sensitivity studies suggest that a better representation of below-cloud scavenging, higher in-cloud collision coefficients, or a reduced water uptake by seasalt aerosols could reduce these biases.

    In the paper, a novel pyrolysis method, namely coal pyrolysis coupling with CO{sub 2} reforming of methane (CRMP) or catalytic pyrolysis of coal coupling with CO{sub 2} reforming of methane (CRMCP), for improving the tar yield of coal pyrolysis was introduced. The behaviours of YM coal in both processes were investigated and compared with pyrolysis under N{sub 2} and H{sub 2}. The results show that the tar yield of coal pyrolysis in both processes obviously increase compared with that in N{sub 2} or H{sub 2}. When YM coal pyrolysis was carried out in stream of mixture gas CH{sub 4}/CO{sub 2} (1:1) with the existence of the catalyst at 0.1 MPa and 800{sup o}C, the tar yield is 2.8 times for CRMP and 4.3 times for CRMCP as that of pyrolysis under N{sub 2} and 1.7 and 2.6 times as that of hydropyrolysis at the same conditions, respectively. Sulfur content of char obtained from CRMP and CRMCP process are lower, especially in CRMP process, than that from N{sub 2} or H{sub 2}. 16 refs., 4 figs., 1 tab.

    Tile analysis of heat energy supply in the production of hydrogen by natural gas steam reforming process has been done. The aim of the study is to compare the energy supply system of conventional and nuclear heat. Methodology used in this study is an assessment of literature and analysis based on the comparisons. The study shows that the heat sources of fossil fuels (natural gas) is able to provide optimum operating conditions of temperature and pressure of 850-900 °C and 2-3 MPa, as well as the heat transfer is dominated by radiation heat transfer, so that the heat flux that can be achieved on the catalyst tube relatively high (50-80 kW/m"2) and provide high thermal efficiency of about 85 %. While in the system with nuclear energy, due to the demands of safety, process operating at less than optimum conditions of temperature and pressure of 800-850 °C and 4.5 MPa, as well as the heat transfer is dominated by convection heat transfer, so that the heat flux that can be achieved catalyst tube is relatively low (1020 kW/m"2) and it provides a low thermal efficiency of about 50 %. Modifications of reformer and heat utilization can increase the heat flux up to 40 kW/m"2 so that the thermal efficiency can reach 78 %. Nevertheless, the application of nuclear energy to hydrogen production with steam reforming process is able to reduce the burning of fossil fuels which has implications for the potential decrease in the rate of CO2 emissions into the environment.

    Beginning in 2005, the Doctor of Veterinary Medicine program at the University of California underwent major curricular review and reform. To provide information for others that follow, we have documented our process and commented on factors that were critical to success, as well as factors we found surprising, difficult, or problematic. The review and reform were initiated by the Executive Committee, who led the process and commissioned the committees. The planning stage took 6 years and involved four faculty committees, while the implementation stage took 5 years and was led by the Curriculum Committee. We are now in year 2 of the institutionalizing stage and no longer refer to our reform as the "new curriculum." The change was driven by a desire to improve the curriculum and the learning environment of the students by aligning the delivery of information with current teaching methodologies and implementing adult learning strategies. We moved from a department- and discipline-based curriculum to a school-wide integrated block curriculum that emphasized student-centered, inquiry-based learning. A limit was placed on in-class time to allow students to apply classroom knowledge by solving problems and cases. We found the journey long and arduous, requiring tremendous commitment and effort. In the change process, we learned the importance of adequate planning, leadership, communication, and a reward structure for those doing the "heavy lifting." Specific to our curricular design, we learned the importance of the block leader role, of setting clear expectations for students, and of partnering with students on the journey.

    In a fixed bed membrane reactor evaluations of methane-carbon dioxide reforming over a Ni/{gamma}- Al{sub 2}O{sub 3} catalyst were performed at 773 K, 823 K and 873 K. A to convert natural gas into syngas a fixed-bed reactor associate with a selective membrane was employed, where the operating procedures allowed to shift the chemical equilibrium of the reaction in the direction of the products of the process. Operations under hydrogen permeation, at 873 K, promoted the increase of methane conversion, circa 83%, and doubled the yield of hydrogen production, when compared with operations where no hydrogen permeation occurred.

    Full Text Available Despite the vast literature on social security reform there are relatively few studies that analyze the participation of representatives coming from the union movement in the decision-making process. This article aims to fill part of that gap in Brazilian academic production on unionism and public policy. In situations in which unionist representatives support the ruling party, does the union bloc tend to defend the specific interests of their base of social representation or to follow the guidance of the party coalition of which they are part? The study addresses this research problemby analyzing the participation of the union bloc in the decision-making process of a social security reform, Proposal of Amendment to the Constitution, Article 40 (PEC 40, during the first term of Luiz Inácio Lula da Silva's government. The main findings of the study confirm the thesis of party predominance. In an institutional political scenario in which party discipline prevails, unionist representatives and senators tend to follow the guidance of the party coalition even under contrary pressures from their electoral base. The research sheds light on the relations involved between the Executive and Legislative branches, in the process of changing public policy, in which a government considered to be allied imposes losses for specific sectors of the union base, notably the active and inactive public servants of the federal government, states and municipalities.

    Directory of Open Access Journals (Sweden)

    Jeltsje Sanne Kemerink

    2016-08-01

    Full Text Available Since the 1980s, a major change took place in public policies for water resources management. Whereas before governments primarily invested in the development, operation and maintenance of water infrastructure and were mainly concerned with the distribution of water, in the new approach they mainly focus on managing water resources systems by stipulating general frameworks for water allocation. This paper studies the rationales used to justify the water reform process in Kenya and discusses how and to what extent these rationales apply to different groups of water users within Likii catchment in the central part of the country. Adopting a critical institutionalist's perspective, this paper shows how the water resource configurations in the catchment are constituted by the interplay between a normative policy model introduced in a plural institutional context and the disparate infrastructural options available to water users as result of historically produced uneven social relations. We argue that, to progressively redress the colonial legacy, direct investments in infrastructure for marginalized water users and targeting the actual (redistribution of water to the users might be more effective than focusing exclusively on institutional reforms.

    A simulation model is developed by commercial simulators in order to predict the performance of a fluidised bed reformer. As many physical and chemical phenomena take place in the reformer, two sub-models (hydrodynamic and reaction sub-models) are needed. The hydrodynamic sub-model is based on the dynamic two-phase model and the reaction sub-model is derived from the literature. In the overall model, the bed is divided into several sections. In each section, the flow of the gas is considered as plug flow through the bubble phase and perfectly mixed through the emulsion phase. Experimental data from the literature were used to validate the model. Close agreement was found between the model of both ASPEN Plus (ASPEN PLUS 2004 ©) and HYSYS (ASPEN HYSYS 2004 ©) and the experimental data using various sectioning of the reactor ranged from one to four. The experimental conversion lies between one and four sections as expected. The model proposed in this work can be used as a framework in developing the complicated models for non-ideal reactors inside of the process simulators.

    2002-01-01

    A life cycle inventory analysis has been conducted to assess the environmental load, specifically CO 2 (fossil) emissions and global warming potential (GWP), associated to the production of hydrogen by the steam reforming of hydrocarbon feedstocks (methane and naphtha) and vegetable oils (rapeseed oil, soybean oil and palm oil). Results show that the GWPs associated with the production of hydrogen by steam reforming in a 100 years time frame are 9.71 and 9.46 kg CO 2 -equivalent/kg H 2 for natural gas and naphtha, respectively. For vegetable oils, the GWP decreases to 6.42 kg CO 2 -equivalent/kg H 2 for rapeseed oil, 4.32 for palm oil and 3.30 for soybean oil. A dominance analysis determined that the part of the process that has the largest effect on the GWP is the steam reforming reaction itself for the fossil fuel-based systems, which accounts for 56.7% and 74% of the total GWP for natural gas and naphtha, respectively. This contribution is zero for vegetable oil-based systems, for which harvesting and oil production are the main sources of CO 2 -eq emissions.(author)

    Full Text Available The types of public investments change from a stage to another. The state always had economical objectives, even if these were not so explicit. However, its role of economy manager developed in the postwar period. The intervention systems diversified and their manipulation becomes more and more frequent. The establishment of intervention types and mechanisms must submit to the requirements. The essential problem is not the global reduction of the state investment, but its efficiency increase. In the current age, the characteristics of a public action are conditioned by the effects of globalization on the state sovereignty, power and capacity. At the end of the past century, debates on this subject were the main focus of the mass media and they emphasized some profound dissensions regarding the nature and implications of globalization.

    The central issue of debate was the need to align the energy sector's options and organization with changing global patterns of economic and social development, characterized by the increasing role played by the private sector, greater integration in the world economy, and new economic and social priorities such as efficiency, decentralization, deregulation, and a closer attention to environmental issues. The aim of the work was to define the economic and political forces of the electric power sector regulation restructuring.

  7. Life Cycle Assessment Of Hydrogen Production From Natural Gas Reforming Process

    2010-01-01

    Society has become concerned about the issues of natural resource depletion and environmental degradation. The environmental performance of products or processes has become a key issue, which is why ways to minimize the effects on the environment are investigated. The most effective tool for this purpose is called life cycle assessment (LCA). This concept considers the entire life cycle of product or process. The life cycle of a product begins with the extraction of raw materials from the earth to create the product and ends at the point when all materials are returned to the earth. LCA makes it possible to estimate the cumulative environmental impacts resulting from all stages in the product life cycle, often including impacts not considered in more traditional analyses. Therefore, LCA provides a comprehensive view of the environmental aspects of the product or process and a more accurate picture of the true environmental trade-offs in product selection. In the case of this study, life cycle assessments of hydrogen production via natural gas reforming process are investigated for environmental affect.

    Highlights: • Aqueous phase reforming: a tailor-made process for the valorisation of crude glycerol. • In-depth understanding of the effect of the operating conditions on the process. • Process optimisation for the selective production of valuable gas and liquid products. • Low pressure and high temperature and spatial time favour gas production. • High pressure and medium temperature maximise the production of valuable liquids. - Abstract: The present work studies the influence of the temperature (200–240 °C), pressure (38–50 bar), glycerol concentration (10–50 wt.%) and mass of catalyst/ glycerol mass flow rate ratio (W/m_g_l_y_c_e_r_o_l = 10–40 g catalyst min/g glycerol) during the aqueous phase reforming (APR) of a glycerol solution obtained from the production of biodiesel. The operating conditions exerted a statistically significant influence on the reforming results. Specifically, the global glycerol conversion and the carbon converted into gas and liquid products varied as follows: 4–100%, 1–80% and 16–93%, respectively. The gas phase was made up of H_2 (8–55 vol.%), CO_2 (34–66 vol.%), CO (0–4 vol.%) and CH_4 (6–45 vol.%). The liquid phase consisted of a mixture of alcohols (monohydric: methanol and ethanol; and polyhydric: 1,2-propanediol, 1,2-ethanediol, 2,3-butanediol), aldehydes (acetaldehyde), ketones (C3-ketones: acetone and 2-propanone-1-hydroxy; C4-ketones: 2-butanone-3-hydroxy and 2-butanone-1-hydroxy; and cyclic ketones), carboxylic acids (acetic and propionic acids) and esters (1,2,3-propanetriol-monoacetate), together with unreacted glycerol and water. The relative amount (free of water and un-reacted glycerol) of these compounds in the liquid phase was as follows: monohydric alcohols: 4–47%, polyhydric-alcohols: 14–68%, aldehydes: 0–5%, C3-ketones: 2–33%, C4-ketones: 0–10%, ciclo-ketones: 0–6%, carboxylic acids: 2–43%, and esters: 0–46%. This process turned out to be highly customisable for the

    In recent years, many teachers suffered different kinds of negative emotions in the context of education reforms. A typical explanation was that the education reforms disempowered teachers in teaching, so teachers were forced to do much non-instructional work. Teachers considered their work meaningless but were powerless to change it, and…

    Full Text Available To survive in the current shipbuilding industry, it is of vital importance for shipyards to have the ship components’ accuracy evaluated efficiently during most of the manufacturing steps. Evaluating components’ accuracy by comparing each component’s point cloud data scanned by laser scanners and the ship’s design data formatted in CAD cannot be processed efficiently when (1 extract components from point cloud data include irregular obstacles endogenously, or when (2 registration of the two data sets have no clear direction setting. This paper presents reformative point cloud data processing methods to solve these problems. K-d tree construction of the point cloud data fastens a neighbor searching of each point. Region growing method performed on the neighbor points of the seed point extracts the continuous part of the component, while curved surface fitting and B-spline curved line fitting at the edge of the continuous part recognize the neighbor domains of the same component divided by obstacles’ shadows. The ICP (Iterative Closest Point algorithm conducts a registration of the two sets of data after the proper registration’s direction is decided by principal component analysis. By experiments conducted at the shipyard, 200 curved shell plates are extracted from the scanned point cloud data, and registrations are conducted between them and the designed CAD data using the proposed methods for an accuracy evaluation. Results show that the methods proposed in this paper support the accuracy evaluation targeted point cloud data processing efficiently in practice.

    2017-04-01

    Full Text Available This paper presents some outside views on the emergence of Chinese constitutional thought. It shows that Chinese constitutionalism in the beginning of the 20th century did matter to the outside world and did attract a large interest on a global scale. Foreign views were quite diverse. While most observers welcomed the adoption of a constitution in principle, there were many words of caution that such a transition should not be rushed, notedly among diplomats and politicians. Foreign powers thus adopted a policy of not pressuring China to adopt a constitution. In particular, this paper redefines the role of the Japanese statesman Itô Hirobumi, who continually tried to give his advice to the Qing government up until his death in 1909.

    In 2011, the Accreditation Council for Graduate Medical Education (ACGME) expanded restrictions on resident duty hours. While studies have shown no association between these restrictions and improved outcomes, process-of-care and patient experience measures may be more sensitive to resident performance, and thus may be impacted by duty hour policies. The objective of this study was to evaluate the association between the 2011 resident duty hour reform and measures of processes-of-care and patient experience. Hospital Consumer Assessment of Healthcare Providers and Systems survey data and process-of-care scores were obtained from the Centers for Medicare and Medicaid Services Hospital Compare website for 1 year prior to (1 July 2010 to 30 June 2011) and 1 year after (1 July 2011 to 30 June 2012) duty hour reform implementation. Using a difference-in-differences model, non-teaching and teaching hospitals were compared before and after the 2011 reform to test the association of this policy with changes in process-of-care and patient experience measure scores. Duty hour reform was not associated with a change in the five patient experience measures evaluated, including patients rating a hospital 9 or 10 (coefficient -0.003, 95% CI -0.79 to 0.79) or stating they would 'definitely recommend' a hospital (coefficient -0.28, 95% CI -1.01 to 0.44). For all 10 process-of-care measures examined, such as antibiotic timing (coefficient -0.462, 95% CI -1.502 to 0.579) and discontinuation (0.188, 95% CI -0.529 to 0.904), duty hour reform was not associated with a change in scores. The 2011 ACGME duty hour reform was not associated with improvements in process-of-care and patient experience measures. These data should be considered when considering reform of resident duty hour policies. Published by the BMJ Publishing Group Limited.

  18. Developing a Steady-state Kinetic Model for Industrial Scale Semi-Regenerative Catalytic Naphtha Reforming Process

    Directory of Open Access Journals (Sweden)

    Seif Mohaddecy, R.

    2014-05-01

    Full Text Available Due to the demand for high octane gasoline as a transportation fuel, the catalytic naphtha reformer has become one of the most important processes in petroleum refineries. In this research, the steady-state modelling of a catalytic fixed-bed naphtha reforming process to predict the momentous output variables was studied. These variables were octane number, yield, hydrogen purity, and temperature of all reforming reactors. To do such a task, an industrial scale semi-regenerative catalytic naphtha reforming unit was studied and modelled. In addition, to evaluate the developed model, the predicted variables i.e. outlet temperatures of reactors, research octane number, yield of gasoline and hydrogen purity were compared against actual data. The results showed that there is a close mapping between the actual and predicted variables, and the mean relative absolute deviation of the mentioned process variables were 0.38 %, 0.52 %, 0.54 %, 0.32 %, 4.8 % and 3.2 %, respectively.

  19. Investigation of hydrogen generation in a three reactor chemical looping reforming process

    2016-01-01

    Highlights: • Three-reactor based chemical looping reforming system for hydrogen production. • Investigation of operating parameters using a system-level model. • Optimum operating conditions for hydrogen production are identified. • Different operating parameters affect the reactor temperatures differently. - Abstract: Chemical looping reforming (CLR) is a relatively new method to produce hydrogen (H_2) and is also used as an energy conversion method for solid, liquid or gaseous fuels. There are various advantages of this method such as inherent carbon dioxide (CO_2) capture, minimal NOx emissions and the H_2 production. In this process, there is no direct contact between the fuel and oxidizer. This method utilizes oxygen from an oxygen carrier which may be a transition metal. The idea is to split the combustion process into three separate sub-processes by employing three separate reactors: air reactor where the oxygen carrier is oxidized by air, fuel reactor where natural gas is oxidized to produce a stream of CO_2 and H_2O and steam reactor where the steam is reduced to produce H_2. In this study, a thermodynamic model with iron oxides as oxygen carrier has been developed using Aspen Plus by employing conservation of mass and energy for all the components of the CLR system. The developed model was employed to investigate the effect of various operating parameters such as mass flow rates of air, fuel, steam and oxygen carrier and fraction of inert material on H_2 and CO_2 production and key reactor temperatures. The results show that the H_2 production increases with the increase in air, fuel and steam flow rates up to a certain limit and stays constant for higher flow rates. The CO_2 production follows a similar trend. Similarly, the H_2 production also increases with the increase in oxide flow rate and fraction of inert material up to a particular value, but then decrease for higher oxide flow rates and inert fractions. Reactor temperatures were also

    Directory of Open Access Journals (Sweden)

    A.L. Rheeder

    2016-09-01

    Full Text Available The 2005 UNESCO Universal Declaration of Bioethics and Human Rights (UDBHR is specifically aimed at Africa and developing countries from other regions. The acceptance of this UNESCO instrument shows that global bioethics and human rights have become part of the bioethics discourse of today. It is clear that there is a certain affinity between human rights and bioethics, which makes such a link desirable. The value of this link lies in the fact that human rights facilitate a normative universal expansion of bioethical principles. The human rights framework provides bioethical principles with some authority and political influence, an instrument that can protect people in our broken context. Human rights practice and a reformed understanding of natural law both show that humanity can reach consensus on ethical principles such as those found in the UDBHR. Consensus on the theoretical foundation of human rights is not a prerequisite for the successful utilisation of these principles.

    This project was focused on developing a catalytic means of producing H2 from raw, ground biomass, such as fast growing poplar trees, willow trees, or switch grass. The use of a renewable, biomass feedstock with minimal processing can enable a carbon neutral means of producing H2 in that the carbon dioxide produced from the process can be used in the environment to produce additional biomass. For economically viable production of H2, the biomass is hydrolyzed and then reformed without any additional purification steps. Any unreacted biomass and other byproduct streams are burned to provide process energy. Thus, the development of a catalyst that can operate in the demanding corrosive environment and presence of potential poisons is vital to this approach. The concept for this project is shown in Figure 1. The initial feed is assumed to be a >5 wt% slurry of ground wood in dilute base, such as potassium carbonate (K2CO3). Base hydrolysis and reforming of the wood is carried out at high but sub-critical pressures and temperatures in the presence of a solid catalyst. A Pd alloy membrane allows the continuous removal of pure , while the retentate, including methane is used as fuel in the plant. The project showed that it is possible to economically produce H2 from woody biomass in a carbon neutral manner. Technoeconomic analyses using HYSYS and the DOE's H2A tool [1] were used to design a 2000 ton day-1 (dry basis) biomass to hydrogen plant with an efficiency of 46% to 56%, depending on the mode of operation and economic assumptions, exceeding the DOE 2012 target of 43%. The cost of producing the hydrogen from such a plant would be in the range of $1/kg H2 to $2/kg H2. By using raw biomass as a feedstock, the cost of producing hydrogen at large biomass consumption rates is more cost effective than steam reforming of hydrocarbons or biomass gasification and can achieve the overall cost goals of the DOE Fuel Cell Technologies Program.

    Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste plastics is reported here using a pyrolysis-reforming technology comprising a two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The waste plastics consisted of plastics from a motor oil container (MOC), commercial waste high density polyethylene (HDPE) and regranulated HDPE waste containing polyvinyl chloride (PVC). The results show that hydrogen can be produced from the pyrolysis-reforming process, but also carbon nanotubes are formed on the catalyst. However, the content of 0.3 wt.% polyvinyl chloride in the waste HDPE (HDPE/PVC) has been shown to poison the catalyst and significantly reduce the quantity and purity of CNTs. The presence of sulfur has shown less influence on the production of CNTs in terms of quantity and CNT morphologies. Around 94.4 mmol H2 g(-1) plastic was obtained for the pyrolysis-reforming of HDPE waste in the presence of the Ni-Mn-Al catalyst and steam at a reforming temperature of 800 °C. The addition of steam in the process results in an increase of hydrogen production and reduction of carbon yield; in addition, the defects of CNTs, for example, edge dislocations were found to be increased with the introduction of steam (from Raman analysis).

    The invention concerns a process for the manufacture of a catalyst suitable for the steam reforming of hydrocarbons or for obtaining methane, by the deposition of the catalytic components on a metal carrier with a large surface area, particularly a process for the manufacture of a solid nickel catalyst, which is suitable for the steam reforming of hydrocarbons, particularly of methane. The following steps of the process are carried out: producing a highly porous layer of spongy metal from Ni powder on the side of a metal wall away from a heat medium, which separates the reaction mixture from the heat medium, then separate application of a non-reducing oxide (Al/sub 2/O/sub 3/) and a reducing oxide (nickel oxide) on the spongy metal by soaking with metal salt solution and then roasting in the temperature range of 400 to 1200/sup 0/C.

    1994-01-01

    The Environmental Assessment and Review Process Guidelines Order (EARP) was the Canadian federal law governing environmental assessment of projects. EARP had been subject to misinterpretation, had been significantly modified in different directions as a result of numerous court cases, and no longer accurately reflected government policy. Parliament therefore passed the Canadian Environmental Assessment Act (CEAA), which received Royal Assent in 1992, but had still not been proclaimed at the time of the conference, pending a review of draft regulations. CEAA will speed up stalled projects, particularly in the Saskatchewan uranium mining industry, by removing uncertainty and by permitting more focussed, flexible, and consistent public reviews; it defines what kind of government projects require approval; it provides for integration of environmental concerns into federal decision making, e.g. by the AECB; it will allow less expensive and more timely environmental assessments

    Full Text Available Regionalism has become one of the most discussed topics at the moment, in recent years and become one of the central challenges of the future in the modern system of international relations. Finally, in the XIX-XX centuries, scientists have expressed it a worldwide phenomenon through a process of radical change "external environment" and significant internal changes. It can be expressed in the world in one way or another, even if it has not been shown modest form until recently. Currently, regionalism and regional integration are considered as key indicators of international developments in the research of foreign policy and international relations. Theory followed the end of the era of "Cold War" and entered the post-bipolar world, multi-faceted development stage. The attention of researchers has grown to regionalization and regional integration by increasing the role and activities of regional organizations such as the EU, ASEAN, APEC and NAFTA, which coordinates the process of decision-making at supranational level, as well as issues of international regulation.

    2017-11-01

    Full Text Available The modern Russian reforms aimed at moving the society to a new stage of development are going through a complicated, contradictory way, with great social costs and zigzags of the political course of power. This poses the task of identifying and overcoming the inhibiting factors in the development of the country. One of the most effective mechanisms of such work is the study of the three-hundred-year experience of Russian reformation and the identification of timeless sociocultural and mental risk factors affecting the nature and content of reforms. This article is devoted to this purpose. In the course of study, we have drawn the conclusions about the deterrent effect on the development of the country of such features of Russian society as its socio-cultural split, absence of internal mechanisms for the self-development of society, lack of a dialogue between government and society, whose relationships are determined by the principle of "antisocial state - anti-state society", mental characteristics of the Russian intelligentsia, which dogmatically implements particular ideas at the expense of economic expediency and common sense, orientation of the ruling elite on the Western values as opposed to national traditions, conservatism and lack of conscious reformative motivation of the masses. This leads to the need to correlate the current reforms not only with the current trends of socio-economic development, but also with the sociocultural foundations of Russian society and the peculiarities of its mentality.

  12. Catalyst Deactivation and Regeneration Processes in Biogas Tri-Reforming Process. The Effect of Hydrogen Sulfide Addition

    Directory of Open Access Journals (Sweden)

    Urko Izquierdo

    2018-01-01

    Full Text Available This work studies Ni-based catalyst deactivation and regeneration processes in the presence of H2S under a biogas tri-reforming process for hydrogen production, which is an energy vector of great interest. 25 ppm of hydrogen sulfide were continuously added to the system in order to provoke an observable catalyst deactivation, and once fully deactivated two different regeneration processes were studied: a self-regeneration and a regeneration by low temperature oxidation. For that purpose, several Ni-based catalysts and a bimetallic Rh-Ni catalyst supported on alumina modified with CeO2 and ZrO2 were used as well as a commercial Katalco 57-5 for comparison purposes. Ni/Ce-Al2O3 and Ni/Ce-Zr-Al2O3 catalysts almost recovered their initial activity. For these catalysts, after the regeneration under oxidative conditions at low temperature, the CO2 conversions achieved—79.5% and 86.9%, respectively—were significantly higher than the ones obtained before sulfur poisoning—66.7% and 45.2%, respectively. This effect could be attributed to the support modification with CeO2 and the higher selectivity achieved for the Reverse Water-Gas-Shift (rWGS reaction after catalysts deactivation. As expected, the bimetallic Rh-Ni/Ce-Al2O3 catalyst showed higher resistance to deactivation and its sulfur poisoning seems to be reversible. In the case of the commercial and Ni/Zr-Al2O3 catalysts, they did not recover their activity.

    Full Text Available This paper explores the impact of globalization in Nepalese women. The changes on the women’s way of life due to globalization can be seen directly in the economy, media, IT sectors, various parts of society and ultimately in the culture. When the Nepalese women entered into the globalization process the Hindu norms and values of the society (where more than 82 percent are Hindu has creolized with the global way of life. The women are becoming more self- reliant and empowered due to globalization but at the same time they are entering more risky markets to fulfill the desires that floated by the globalization. Similarly, globalization has offered various employment opportunities and exposure in international arena, but it also creates mental anxiety, depression and sexual abuse for those remaining in or outside the country. As there is very limited research and study on the impact of globalization in the Nepalese society, it is too early to conclude the impact of globalization as good or bad on Nepalese women.

  17. Processes of social flourishing and their liminal collapse: elements to a genealogy of globalization.

    Science.gov (United States)

    Szakolczai, Arpad

    2016-09-01

    This article aims at exploring a long-term historical perspective on which contemporary globalization can be more meaningfully situated. A central problem with established approaches to globalization is that they are even more presentist than the literature on modernization was. Presentism not only means the ignoring of history, but also the unreflective application to history of concepts taken from the study of the modern world. In contrast, it is argued that contemporary globalization is not a unique development, but rather is a concrete case of a historical type. Taking as its point of departure the spirit, rather than the word, of Max Weber, this article extends the scope of sociological investigation into archaeological evidence. Having a genealogical design and introducing the concept of 'liminality', the article approaches the modern process of globalization through reconstructing the internal dynamics of another type of historical change called 'social flourishing'. Taking up the Weberian approach continued by Eisenstadt in his writings on 'axial age', it moves away from situations of crisis as reference point, shifting attention to periods of revival by introducing the term 'epiphany'. Through the case of early Mesopotamia, it shows how social flourishing can be transmogrified into globalizing growth, gaining a new perspective concerning the kind of 'animating spirit' that might have driven the shift from Renaissance to Reformation, the rise of modern colonialism, or contemporary globalization. More generally, it will retrieve the long-term historical background of the axial age and demonstrate the usefulness and importance of archaeological evidence for sociology. © London School of Economics and Political Science 2016.

    Janardhanan, Vinod M.; Deutschmann, Olaf

    Direct internal reforming in solid oxide fuel cell (SOFC) results in increased overall efficiency of the system. Present study focus on the chemical and electrochemical process in an internally reforming anode supported SOFC button cell running on humidified CH 4 (3% H 2 O). The computational approach employs a detailed multi-step model for heterogeneous chemistry in the anode, modified Butler-Volmer formalism for the electrochemistry and Dusty Gas Model (DGM) for the porous media transport. Two-dimensional elliptic model equations are solved for a button cell configuration. The electrochemical model assumes hydrogen as the only electrochemically active species. The predicted cell performances are compared with experimental reports. The results show that model predictions are in good agreement with experimental observation except the open circuit potentials. Furthermore, the steam content in the anode feed stream is found to have remarkable effect on the resulting overpotential losses and surface coverages of various species at the three-phase boundary.

    Full Text Available Abstract. Once with the Romania adhering at the European Union the public accounting system was transformed and adapted according to the requirements imposed by the international public sector accounting standards (IPSAS.This fact had imposed the appearance of legislative norms and provisions adapted to the actual requirements, by taking into account the growing and complex level of economic activities where the irreversible process of globalization takes place. The changes due to the economic politics, especially the new configuration of the international economic relations, relations characterized by an intense and irreversible process of globalization, have conducted to the implementation of a unitary and uniform legislation, particularly for the member states of EU. The accounting reform has begun through the harmonization of legislation according to the requirements and provisions of International Accounting Standards and European Directives.  The ampleness and the rapid rhythm of informational society’s development have implicitly leaded to the development of accounting information’s importance and dimension. The decisive role of the accounting information had conducted to the accentuated growth of the interest, manifested at all informational society’s level, from the development of activities in financial and economical domain point of view. The accounting normalization process imposed the development of norms and provisions necessary to the drawing up of accounting documents, by defying methods and a specialized terminology, applied in the activity of entities and accounting specialists.

    2007-05-22

    This paper assesses progress in the development of a global framework for responding to non-communicable diseases, as reflected in the policies and initiatives of the World Health Organization (WHO), World Bank and the UN: the institutions most capable of shaping a coherent global policy. Responding to the global burden of chronic disease requires a strategic assessment of the global processes that are likely to be most effective in generating commitment to policy change at country level, and in influencing industry behaviour. WHO has adopted a legal process with tobacco (the WHO Framework Convention on Tobacco Control), but a non-legal, advocacy-based approach with diet and physical activity (the Global Strategy on Diet, Physical Activity and Health). The paper assesses the merits of the Millennium Development Goals (MDGs) and the FCTC as distinct global processes for advancing health development, before considering what lessons might be learned for enhancing the implementation of the Global Strategy on Diet. While global partnerships, economic incentives, and international legal instruments could each contribute to a more effective global response to chronic diseases, the paper makes a special case for the development of international legal standards in select areas of diet and nutrition, as a strategy for ensuring that the health of future generations does not become dependent on corporate charity and voluntary commitments. A broader frame of reference for lifestyle-related chronic diseases is needed: one that draws together WHO's work in tobacco, nutrition and physical activity, and that envisages selective use of international legal obligations, non-binding recommendations, advocacy and policy advice as tools of choice for promoting different elements of the strategy.

    Khinkis, Mark J.; Kozlov, Aleksandr P.; Kurek, Harry

    2015-12-22

    A non-catalytic recuperative reformer has a flue gas flow path for conducting hot flue gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is embedded in the flue gas flow path to permit heat transfer from the hot flue gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, extended surfaces of metal material such as stainless steel or metal alloy that are high in nickel content are included within at least a portion of the reforming mixture flow path.

  6. A comprehensive energy–exergy-based assessment and parametric study of a hydrogen production process using steam glycerol reforming

    2014-01-01

    Various assessment tools are applied to comprehensively investigate a glycerol-to-hydrogen production system. These tools investigate the chemical reactions, design and simulate the entire hydrogen production process, study the energetic and exergetic performances and perform parametric analyses (using intuitive and design of experiment-based methods). Investigating the chemical reaction of steam glycerol reforming reveals that the optimal conditions, determined based on maximizing the hydrogen production while minimizing the methane and carbon monoxide contents and coke formation, can be achieved at a reforming temperature and a water-to-glycerol feed ratio (WGFR) of 950 K and 9, respectively. The thermal and exergetic efficiencies of the resulting process are 66.6% and 59.9%, respectively. These findings are lower than those cited in the literature and relative to other reformates (methane, ethanol and methanol). The parametric investigation indicates that the performance of the process (energetic and exergetic) could be ensured by using an appropriate and judiciously selected combination of the reactor temperature and WGFR. Based on the parametric energetic and exergetic investigation, WGFR = 6 and T = 1100 K appear to be the most accurate parameters for the entire glycerol-to-hydrogen process. For this recommend configuration, the thermal and exergetic efficiencies are 78.1% and 66.1%, respectively. - Highlights: • Energy and exergy analysis are used to assess glycerol-to-hydrogen process. • Recommended conditions for glycerol-to-hydrogen process are WGFR = 6 and T = 1100 K. • For recommend conditions, thermal and exergetic efficiencies are 78.1% and 66.1%. • Energy and exergy consideration should be included by engineers and scientists

    The influences of globalization have permeated various aspects of life in contemporary society, from technical innovations, economic development, and lifestyles, to communication patterns. The present research proposed a construct termed global orientation to denote individual differences in the psychological processes of acculturating to the globalizing world. It encompasses multicultural acquisition as a proactive response and ethnic protection as a defensive response to globalization. Ten studies examined the applicability of global orientations among majority and minority groups, including immigrants and sojourners, in multicultural and relatively monocultural contexts, and across Eastern and Western cultures. Multicultural acquisition is positively correlated with both independent and interdependent self-construals, bilingual proficiency and usage, and dual cultural identifications. Multicultural acquisition is promotion-focused, while ethnic protection is prevention-focused and related to acculturative stress. Global orientations affect individuating and modest behavior over and above multicultural ideology, predict overlap with outgroups over and above political orientation, and predict psychological adaptation, sociocultural competence, tolerance, and attitudes toward ethnocultural groups over and above acculturation expectations/strategies. Global orientations also predict English and Chinese oral presentation performance in multilevel analyses and the frequency and pleasantness of intercultural contact in cross-lagged panel models. We discuss how the psychological study of global orientations contributes to theory and research on acculturation, cultural identity, and intergroup relations. (c) 2016 APA, all rights reserved).

But a system that has long been effectively regulate social and labor issues within the country, today has almost no effect on the new international system of economic and industrial relations. So now we can see the modernization actors of social partnership policy, especially employers and workers.The most intensively developed in the present conditions employers and entrepreneurs, which in most cases is the cause of the evolution of economic and social development in the world. Now there is a tendency to increase the number and impact of international non­governmental organizations, including trade unions.In modern terms, it is necessary to strengthen control over the implementation of the agreements, which should be based on consideration of international agreements and establishing a mechanism to coordinate rapid response of international agencies, trade unions and employers associations.The direction of the Ukrainian state promotes global social partnership is to promote businesses joining the UN Global Compact, which is the world’s largest voluntary initiative of business, UN agencies, labor, civil society organizations and government in the area of corporate social responsibility.

    Full Text Available One of the most significant procedures in oil refineries is naphtha catalytic reforming unit in which high octane gasoline is gained. Normally, in oil refineries, flow instability in the composition of feedstock can affect the product quality. The aim of the present work was focused on modifications of the final product flow rate and product’s octane number with respect to the modifications of the feedstock composition. The main three reforming reactions investigated, namely; dehydrogenation, dehydrocyclization, and hydrocracking were conducted employing silica supported bimetallic (Pt-Re patented catalyst. Optimization of the catalytic process reaction conditions, i.e.; temperature, hydrogen pressure and liquid hourly space velocity (LHSV was carried out with regard to conversion and selectivity. The optimization results indicated that heavy naphtha component conversion (paraffin’s and naphthenes increases with an increasing in reaction temperature and pressure while decreases with an increase in LHSV. The kinetic study of catalytic reforming reactions reported helped establishing the reaction model explicitly.

    2017-11-01

    Full Text Available The modeling of carbon deposition from C-H-O reformates has usually employed thermodynamic data for graphite, but has rarely employed such data for impure filamentous carbon. Therefore, electrochemical data for the literature on the chemical potential of two types of purified carbon nanotubes (CNTs are included in the study. Parameter values determining the thermodynamic equilibrium of the deposition of either graphite or CNTs are computed for dry and wet reformates from natural gas and liquefied petroleum gas. The calculation results are presented as the atomic oxygen-to-carbon ratio (O/C against temperature (200 to 100 °C for various pressures (1 to 30 bar. Areas of O/C for either carbon deposition or deposition-free are computed, and indicate the critical O/C values below which the deposition can occur. Only three types of deposited carbon were found in the studied equilibrium conditions: Graphite, multi-walled CNTs, and single-walled CNTs in bundles. The temperature regions of the appearance of the thermodynamically stable forms of solid carbon are numerically determined as being independent of pressure and the analyzed reactants. The modeling indicates a significant increase in the critical O/C for the deposition of CNTs against that for graphite. The highest rise in the critical O/C, of up to 290% at 30 bar, was found for the wet reforming process.

  13. Collaboration in Global Software Engineering Based on Process Description Integration

    Science.gov (United States)

    Klein, Harald; Rausch, Andreas; Fischer, Edward

    Globalization is one of the big trends in software development. Development projects need a variety of different resources with appropriate expert knowledge to be successful. More and more of these resources are nowadays obtained from specialized organizations and countries all over the world, varying in development approaches, processes, and culture. As seen with early outsourcing attempts, collaboration may fail due to these differences. Hence, the major challenge in global software engineering is to streamline collaborating organizations towards a successful conjoint development. Based on typical collaboration scenarios, this paper presents a structured approach to integrate processes in a comprehensible way.

    Zhou, Jiawei; Huang, Pi-Chun; Hess, Robert F

    2013-04-22

    We developed a dichoptic global orientation coherence paradigm to quantify interocular suppression in amblyopia. This task is biased towards ventral processing and allows comparison with two other techniques-global motion processing, which is more dorsally biased, and binocular phase combination, which most likely reflects striate function. We found a similar pattern for the relationship between coherence threshold and interocular contrast curves (thresholds vs. interocular contrast ratios or TvRs) in our new paradigm compared with those of the previous dichoptic global motion coherence paradigm. The effective contrast ratios at balance point (where the signals from the two eyes have equal weighting) in our new paradigm were larger than those of the dichoptic global motion coherence paradigm but less than those of the binocular phase combination paradigm. The measured effective contrast ratios in the three paradigms were also positively correlated with each other, with the two global coherence paradigms having the highest correlation. We concluded that: (a) The dichoptic global orientation coherence paradigm is effective in quantifying interocular suppression in amblyopia; and (b) Interocular suppression, while sharing a common suppression mechanism at the early stage in the pathway (e.g., striate cortex), may have additional extra-striate contributions that affect both dorsal and ventral streams differentially.

    Full Text Available The Superior Council of Magistracy represent a cornerstone of the Romanian court management system. This responsibility is partly shared with the Ministry of Justice. The reform of the court management system in Romania has been and still is disputable, the main actors being on one hand the magistrates and on the other the Ministry of Justice. While observing this „dispute“ we may discover a third actor, namely the European Union, who has entered scene in the context of Romania’s European integration. This research is looking to plausibly explain which was the part played by the EU and how did it influence the above mentioned reform, with special emphasis on the Superior Council of Magistracy.

  19. The Transference of Gender-based Norms in the Law Reform Process: A Reflection on my Work in Thailand

    Directory of Open Access Journals (Sweden)

    Y-Vonne Hutchinson

    2013-04-01

    Full Text Available In 2008, I spent a year as a Rule of Law specialist in Thailand with the International Rescue Committee (IRC, as part of a fellowship program for human rights lawyers. I was assigned the task of facilitating the development of a comprehensive legal code for the refugee camps along the border between Thailand and /Burma. As part of my work, I also sought to increase gender-based protection under the law through the incorporation of Thai and international human rights norms. This paper is a reflection on the processes that occurred during my time at IRC. The reform project approached the transference of contentious international norms for protection of women and girls in two ways: a through the inclusive design of the law reform process and b the establishment of a prohibition on rules that clearly violated international or national law. By forming a representative drafting committee and placing an emphasis on community consultation as a precursor to code finalisation, refugee perspectives, particularly female perspectives, were given scope to inform interpretations of national and international legal standards. By requiring international and national legal compliance and placing an emphasis on explanation and clarification of international and national standards in discussions, the project supported downward transference of international norms to a specific community context. We hoped that, as a product of these two normative flows, the resulting legal code would be a sustainable mechanism for gender-based protection and redress in cases of sexual and gender-based violence. During negotiations, it became evident that the inclusive design of the law reform process had a more positive impact on the success of norms transference than the actual substance of the norm. The norms that were most readily accepted were those introduced by law reform committee members themselves. Local norm translators played a pivotal role in the norms diffusion process

  20. Performance and economic assessments of a solid oxide fuel cell system with a two-step ethanol-steam-reforming process using CaO sorbent

    The hydrogen production process is known to be important to a fuel cell system. In this study, a carbon-free hydrogen production process is proposed by using a two-step ethanol-steam-reforming procedure, which consists of ethanol dehydrogenation and steam reforming, as a fuel processor in the solid oxide fuel cell (SOFC) system. An addition of CaO in the reformer for CO2 capture is also considered to enhance the hydrogen production. The performance of the SOFC system is analyzed under thermally self-sufficient conditions in terms of the technical and economic aspects. The simulation results show that the two-step reforming process can be run in the operating window without carbon formation. The addition of CaO in the steam reformer, which runs at a steam-to-ethanol ratio of 5, temperature of 900 K and atmospheric pressure, minimizes the presence of CO2; 93% CO2 is removed from the steam-reforming environment. This factor causes an increase in the SOFC power density of 6.62%. Although the economic analysis shows that the proposed fuel processor provides a higher capital cost, it offers a reducing active area of the SOFC stack and the most favorable process economics in term of net cost saving.

    A bibliographic review allows to understand very quickly the stake that the electric-powered vehicle represents. The research of a hydrogen production process answering to the demands of the fuel cell application is then one of the main stakes. The catalytic steam reforming of hydrocarbons or of alcohols is a very promising way. The choices of ethanol and of rhodium based catalysts supported on oxides with strong oxygen mobility will be entirely justified because of the physico-chemical characteristics of the ethanol, of the reaction mechanism, of the cerium based oxide catalyst and of the specifications involved in the fuel cell application.

    Steady increases in alcohol consumption and related problems are likely to accompany China's rapid epidemiological transition and profit-based marketing activities. We reviewed research on health promotion interventions and policies to address excessive drinking and to guide health-care reform. We searched Chinese- and English-language databases and included 21 studies in China published between 1980 and 2013 that covered each policy area from the World Health Organization (WHO) Global Strategy to Reduce the Harmful Use of Alcohol. We evaluated and compared preventive interventions to the global alcohol literature for cross-national applicability. In contrast with hundreds of studies in the global literature, 11 of 12 studies from mainland China were published in Chinese; six of 10 in English were on taxation from Taiwan or Hong Kong. Most studies demonstrated effectiveness in reducing excessive drinking, and some reported the reduction of health problems. Seven were randomized controlled trials. Studies targeted schools, drink-driving, work-places, the health sector and taxation. China is the world's largest alcohol market, yet there has been little growth in alcohol policy research related to health promotion interventions over the past decade. Guided by a public health approach, the WHO Global Strategy and health reform experience in Russia, Australia, Mexico and the United States, China could improve its public health response through better coordination and implementation of surveillance and evidence-based research, and through programmatic and legal responses such as public health law research, screening and early intervention within health systems and the implementation of effective alcohol control strategies. © 2014 Society for the Study of Addiction.

  3. The effect of sadness on global-local processing.

    Gable and Harmon-Jones (Psychological Science, 21(2), 211-215, 2010) reported that sadness broadens attention in a global-local letter task. This finding provided the key test for their motivational intensity account, which states that the level of spatial processing is not determined by emotional valence, but by motivational intensity. However, their finding is at odds with several other studies, showing no effect, or even a narrowing effect of sadness on attention. This paper reports two attempts to replicate the broadening effect of sadness on attention. Both experiments used a global-local letter task, but differed in terms of emotion induction: Experiment 1 used the same pictures as Gable and Harmon-Jones, taken from the IAPS dataset; Experiment 2 used a sad video underlaid with sad music. Results showed a sadness-specific global advantage in the error rates, but not in the reaction times. The same null results were also found in a South-Asian sample in both experiments, showing that effects on global/local processing were not influenced by a culturally related processing bias.

    Patients who have difficulties recognising visual form stimuli are usually labelled as having visual agnosia. However, recent studies let us identify different clinical manifestations corresponding to discrete diagnostic entities which reflect a variety of deficits along the continuum of cortical visual processing. We reviewed different clinical cases published in medical literature as well as proposals for classifying deficits in order to provide a global perspective of the subject. Here, we present the main findings on the neuroanatomical basis of visual form processing and discuss the criteria for evaluating processing which may be abnormal. We also include an inclusive diagram of visual form processing deficits which represents the different clinical cases described in the literature. Lastly, we propose a boosted decision tree to serve as a guide in the process of diagnosing such cases. Although the medical community largely agrees on which cortical areas and neuronal circuits are involved in visual processing, future studies making use of new functional neuroimaging techniques will provide more in-depth information. A well-structured and exhaustive assessment of the different stages of visual processing, designed with a global view of the deficit in mind, will give a better idea of the prognosis and serve as a basis for planning personalised psychostimulation and rehabilitation strategies.

  5. Global warming potential of the sulfur-iodine process using life cycle assessment methodology

    International Nuclear Information System (INIS)

    Lattin, William C.; Utgikar, Vivek P.

    2009-01-01

    A life cycle assessment (LCA) of one proposed method of hydrogen production - thermochemical water-splitting using the sulfur-iodine cycle couple with a very high-temperature nuclear reactor - is presented in this paper. Thermochemical water-splitting theoretically offers a higher overall efficiency than high-temperature electrolysis of water because heat from the nuclear reactor is provided directly to the hydrogen generation process, instead of using the intermediate step of generating electricity. The primary heat source for the S-I cycle is an advanced nuclear reactor operating at temperatures corresponding to those required by the sulfur-iodine process. This LCA examines the environmental impact of the combined advanced nuclear and hydrogen generation plants and focuses on quantifying the emissions of carbon dioxide per kilogram of hydrogen produced. The results are presented in terms of global warming potential (GWP). The GWP of the system is 2500 g carbon dioxide-equivalent (CO 2 -eq) per kilogram of hydrogen produced. The GWP of this process is approximately one-sixth of that for hydrogen production by steam reforming of natural gas, and is comparable to producing hydrogen from wind- or hydro-electric conventional electrolysis.

  6. Property rights and water markets in Australia: An evolutionary process toward institutional reform

    Science.gov (United States)

    Pigram, John J.

    1993-04-01

    In the past decade far-reaching reforms have taken place in the Australian water industry. Extensive restructuring of water administration has been accompanied by increased evidence of willingness by public agencies to consider alternative institutional arrangements to the traditional regulatory approach to water allocation and use. In irrigated agriculture, a market-based system linked to enforceable property rights to water is seen as preferable to rule-based management of water resources. However, significant social and economic considerations and political realities constrain the unfettered operation of water markets. The challenge facing the irrigation industry in Australia is to put in place institutional arrangements which reflect the most appropriate mix of incentive-based and regulatory mechanisms for water management.

    Direct internal reforming in solid oxide fuel cell (SOFC) results in increased overall efficiency of the system. Present study focus on the chemical and electrochemical process in an internally reforming anode supported SOFC button cell running on humidified CH{sub 4} (3% H{sub 2} O). The computational approach employs a detailed multi-step model for heterogeneous chemistry in the anode, modified Butler-Volmer formalism for the electrochemistry and Dusty Gas Model (DGM) for the porous media transport. Two-dimensional elliptic model equations are solved for a button cell configuration. The electrochemical model assumes hydrogen as the only electrochemically active species. The predicted cell performances are compared with experimental reports. The results show that model predictions are in good agreement with experimental observation except the open circuit potentials. Furthermore, the steam content in the anode feed stream is found to have remarkable effect on the resulting overpotential losses and surface coverages of various species at the three-phase boundary.

  9. A Process-based Model of Global Lichen Productivity

    Science.gov (United States)

    Porada, P.; Kleidon, A.

    2012-04-01

    Lichens and biotic crusts are abundant in most ecosystems of the world. They are the main autotrophic organisms in many deserts and at high altitudes and they can also be found in large amounts as epiphytes in some forests, especially in the boreal zone. They are characterised by a great variety of physiological properties, such as growth form, productivity or color. Due to the vast land surface areas covered by lichens, they may contribute significantly to the global terrestrial net carbon uptake. Furthermore, they potentially play an important role with respect to nutrient cycles in some ecosystems and they have the ability to enhance weathering at the surface on which they grow. A possible way to quantify these processes at the global scale is presented here in form of a process-based lichen model. This approach is based on the concepts used in many dynamical vegetation models and extends these methods to account for the specific properties of lichens. Hence, processes such as photosynthesis, respiration and water exchange are implemented as well as important trade-offs like photosynthetic capacity versus respiratory load and water content versus CO2 conductivity. The great physiological variability of lichens is incorporated directly into the model through ranges of possible parameter values, which are randomly sampled. In this way, many artificial lichen "species" are created and climate then acts as a filter to determine the species which are able to survive permanently. By averaging over the surviving "species", the model predicts lichen productivity as a function of climate input data such as temperature, radiation and precipitation at the global scale. Consequently, the contribution of lichens to the global carbon balance can be quantified. Moreover, global patterns of lichen biodiversity and other properties can be illustrated. The model can be extended to account for the nutrient dynamics of lichens, such as nitrogen fixation and the acquisition and

  11. Adjusting process count on demand for petascale global optimization

    2013-01-01

    There are many challenges that need to be met before efficient and reliable computation at the petascale is possible. Many scientific and engineering codes running at the petascale are likely to be memory intensive, which makes thrashing a serious problem for many petascale applications. One way to overcome this challenge is to use a dynamic number of processes, so that the total amount of memory available for the computation can be increased on demand. This paper describes modifications made to the massively parallel global optimization code pVTdirect in order to allow for a dynamic number of processes. In particular, the modified version of the code monitors memory use and spawns new processes if the amount of available memory is determined to be insufficient. The primary design challenges are discussed, and performance results are presented and analyzed.

    2017-01-01

    There is accumulating evidence suggesting that a central deficit in developmental prosopagnosia (DP), a disorder characterized by profound and lifelong difficulties with face recognition, concerns impaired holistic processing. Some of this evidence comes from studies using Navon’s paradigm where...... that this reduced global precedence effect correlates both with the DPs’ face recognition abilities, as well as their ability to recognize degraded (non-face) objects. We suggest that the DPs’ impaired performance in all three domains (Navon, face and object recognition) may be related to the same dysfunction...

  15. Bureaucratic Reform in Irrigation: A Review of Four Case Studies

    Directory of Open Access Journals (Sweden)

    Diana Suhardiman

    2014-10-01

    Full Text Available Poor performance of government-managed irrigation systems persists globally. This paper argues that addressing performance requires not simply more investment or different policy approaches, but reform of the bureaucracies responsible for irrigation management. Based on reform experiences in The Philippines, Mexico, Indonesia, and Uzbekistan, we argue that irrigation (policy reform cannot be treated in isolation from the overall functioning of government bureaucracies and the wider political structure of the states. Understanding of how and why government bureaucracies shape reform processes and outcomes is crucial to increase the actual significance of reforms. To demonstrate this, the paper links reform processes in the irrigation sector with the wider discourse of bureaucratic reform in the political science, public administration, and organisational science literature. Doing so brings to light the need for systematic comparative research on the organisational characteristic of the irrigation bureaucracies, their bureaucratic identities, and how these are shaped by various segments within the bureaucracies to provide the insights needed to improve irrigation systems performance.

  16. The patents-based pharmaceutical development process: rationale, problems, and potential reforms.

    Barton, John H; Emanuel, Ezekiel J

    2005-10-26

    The pharmaceutical industry is facing substantial criticism from many directions, including financial barriers to access to drugs in both developed and developing countries, high profits, spending on advertising and marketing, and other issues. Underlying these criticisms are fundamental questions about the value of the current patent-based drug development system. Six major problems with the patent system are (1) recovery of research costs by patent monopoly reduces access to drugs; (2) market demand rather than health needs determines research priorities; (3) resources between research and marketing are misallocated; (4) the market for drugs has inherent market failures; (5) overall investment in drug research and development is too low, compared with profits; and (6) the existing system discriminates against US patients. Potential solutions fall into 3 categories: change in drug pricing through either price controls or tiered pricing; change in drug industry structure through a "buy-out" pricing system or with the public sector acting as exclusive research funder; and change in development incentives through a disease burden incentive system, orphan drug approaches, or requiring new drugs to demonstrate improvement over existing products prior to US Food and Drug Administration approval. We recommend 4 complementary reforms: (1) having no requirement to test new drug products against existing products prior to approval but requiring rigorous comparative postapproval testing; (2) international tiered pricing and systematic safeguards to prevent flow-back; (3) increased government-funded research and buy-out for select conditions; and (4) targeted experiments using other approaches for health conditions in which there has been little progress and innovation over the last few decades.

  17. The rise and fall of French Ecological Tax Reform: social acceptability versus political feasibility in the energy tax implementation process

    International Nuclear Information System (INIS)

    Deroubaix, Jose-Frederic; Leveque, Francois

    2006-01-01

    The French government has a 10-year history of negotiations with industry, resulting in voluntary agreements on energy consumption. When implemented, these voluntary agreements produced very few results in terms of global reduction of greenhouse emissions (Politiques et Management Public 11(4) (1993) 47), hence the idea of an energy tax became increasingly attractive for many French decision-makers. Ecological/Environmental Tax Reform (ETR) should have been one of the major political decisions and successes of the past leftwing coalition government. Instead it became one of its major failures as the Constitutional Court decided to terminate the energy tax project in December 2000. Through insights gleaned from focus groups and interviews with business-people and decision-makers, an attempt is made to understand the failure of the energy tax project. Firstly, decision-makers lacked crucial information about public and business opinions and secondly, there were conflicts between the relevant administrations. The fuel revolts of 2000 ended any hope of resolving the conflicts and implementing ETR, which was ultimately found unconstitutional. This paper examines the political controversies raised by the ETR project and the reasons for its eventual collapse, in the hope of contributing new understanding to the body of knowledge on the political difficulties of introducing environmental policy instruments.

    2015-08-01

    Full Text Available Considered an innovation because of its capacity to develop transnational processes, the World Social Forum however also has strong local roots as well as effects on organizational models and collective identities at the domestic level. Focusing on the Italian case, this article shows how local social forums, as arenas for exchanges of ideas, played a cognitive role in the import, but also the translation of new ideas, as well as helping the emergence of dense network structures and tolerant identities. The first section of the article examines how local social forums contributed to innovation in the organizational formulas of the Global Justice Movement—considering both structure (organizations and process (methodologies aspects—through the development of different, more participatory conceptions of internal decision making. It then addresses the innovations in the definition of collective identities, stressing the linkages of local struggles and global framing as well as the development of a cross-issue discourse around an anti-neoliberal frame. The final section will discuss the contribution of local social forums to contemporary social movements, stressing the role of these new arenas for the cross-fertilization among different movement families and spreading a method of working together that becomes part of the repertoire of action of local social movement organizations. The empirical research consists mainly of in-depth interviews and focus groups with activists from social movement organizations which were involved in local social forums.

  19. Physical Processes for Driving Ionospheric Outflows in Global Simulations

    Moore, Thomas Earle; Strangeway, Robert J.

    2009-01-01

    We review and assess the importance of processes thought to drive ionospheric outflows, linking them as appropriate to the solar wind and interplanetary magnetic field, and to the spatial and temporal distribution of their magnetospheric internal responses. These begin with the diffuse effects of photoionization and thermal equilibrium of the ionospheric topside, enhancing Jeans' escape, with ambipolar diffusion and acceleration. Auroral outflows begin with dayside reconnexion and resultant field-aligned currents and driven convection. These produce plasmaspheric plumes, collisional heating and wave-particle interactions, centrifugal acceleration, and auroral acceleration by parallel electric fields, including enhanced ambipolar fields from electron heating by precipitating particles. Observations and simulations show that solar wind energy dissipation into the atmosphere is concentrated by the geomagnetic field into auroral regions with an amplification factor of 10-100, enhancing heavy species plasma and gas escape from gravity, and providing more current carrying capacity. Internal plasmas thus enable electromagnetic driving via coupling to the plasma, neutral gas and by extension, the entire body " We assess the Importance of each of these processes in terms of local escape flux production as well as global outflow, and suggest methods for their implementation within multispecies global simulation codes. We complete 'he survey with an assessment of outstanding obstacles to this objective.

  20. Local and global limits on visual processing in schizophrenia.

    Marc S Tibber

    Full Text Available Schizophrenia has been linked to impaired performance on a range of visual processing tasks (e.g. detection of coherent motion and contour detection. It has been proposed that this is due to a general inability to integrate visual information at a global level. To test this theory, we assessed the performance of people with schizophrenia on a battery of tasks designed to probe voluntary averaging in different visual domains. Twenty-three outpatients with schizophrenia (mean age: 40±8 years; 3 female and 20 age-matched control participants (mean age 39±9 years; 3 female performed a motion coherence task and three equivalent noise (averaging tasks, the latter allowing independent quantification of local and global limits on visual processing of motion, orientation and size. All performance measures were indistinguishable between the two groups (ps>0.05, one-way ANCOVAs, with one exception: participants with schizophrenia pooled fewer estimates of local orientation than controls when estimating average orientation (p = 0.01, one-way ANCOVA. These data do not support the notion of a generalised visual integration deficit in schizophrenia. Instead, they suggest that distinct visual dimensions are differentially affected in schizophrenia, with a specific impairment in the integration of visual orientation information.

    Since 2000, disasters at Texas City, Toulouse, Antwerp, Buncefield, P-36 and several near total loss events offshore in Norway have highlighted that major accident process safety is still a serious issue. Hopes that Process Safety Management or Safety Case regulations would solve these issues have not proven true. The Baker Panel recommended to BP several actions mainly around leadership, incentives, metrics, safety culture and more effective implementation of PSM systems. In Europe, an approach built around mechanical integrity and safety barriers, especially relating to technical safety systems, is being widely adopted. DNV has carried out a global survey of process industry initiatives, by interview and by literature review, for both upstream and downstream activities, to identify what the industry itself is planning to implement to enhance process safety in the next 5 - 10 years. This shows that an approach combining Baker Panel and EU barrier approaches and some nuclear industry real-time risk management approaches might be the best means to achieve a factor of 3-4 improvement in process safety.

    In this study, the hydrogen selling price from ethanol steam reforming has been estimated for two different production scenarios in the United States, i.e. central production (150,000 kg H 2 /day) and distributed (forecourt) production (1500 kg H 2 /day), based on a process flowchart generated by Aspen Plus registered including downstream purification steps and economic analysis model template published by the U.S Department of Energy (DOE). The effect of several processing parameters as well as catalyst properties on the hydrogen selling price has been evaluated. 2.69/kg is estimated as the selling price for a central production process of 150,000 kg H 2 /day and 4.27/kg for a distributed hydrogen production process at a scale of 1500 kg H 2 /day. Among the parameters investigated through sensitivity analyses, ethanol feedstock cost, catalyst cost, and catalytic performance are found to play a significant role on determining the final hydrogen selling price.

  3. To disclose or not to disclose: How global competition for foreign direct investment influences transparency reforms in extractive industries

    International Nuclear Information System (INIS)

    Öge, Kerem

    2016-01-01

    In the last decade, the Extractive Industries Transparency Initiative (EITI) has grown in both popularity and influence. The ascendance of EITI is surprising because traditionally, leaders of resource-rich states prefer to tightly control their extractive industries. This paper investigates the underlying causes of EITI membership in order to understand its acceptance, even among some of the most authoritarian regimes. The paper argues that leaders of resource-rich countries use the EITI to consolidate their international prestige as eager reformers, which serves to both maintain and lure foreign investment. The cross-national and interrupted time series analyses reveal that EITI members not only have higher FDI levels compared to non-members, but these investments increase once countries join the initiative. - Highlights: • I investigate the underlying causes of EITI membership. • I argue that leaders use the EITI to both maintain and lure foreign investment. • EITI members have higher FDI levels compared to non-members. • FDI levels increase once countries join the EITI. • The results highlight a utilitarian use of the EITI by corrupt governments.

    Increasing CO_2 emission problems create urgent challenges for alleviating global warming, and the capture of CO_2 has become an essential field of scientific research. In this study, a finite volume method (FVM) coupled with thermochemical kinetics was developed to analyze the solar driven CO_2 methane reforming process in a metallic foam reactor. The local thermal non-equilibrium (LTNE) model coupled with radiative heat transfer was developed to provide more temperature information. A joint inversion method based on chemical process software and the FVM coupled with thermochemical kinetics was developed to obtain the thermochemical reaction parameters and guarantee the calculation accuracy. The detailed thermal and thermochemical performance in the metal foam reactor was analyzed. In addition, the effects of heat flux distribution and porosity on the solar driven CO_2 methane reforming process were analyzed. The numerical results can serve as theoretical guidance for the solar driven CO_2 methane reforming application. - Highlights: • Solar driven CO_2 methane reforming process in metal foam reactor is analyzed. • FVM with chemical reactions was developed to analyze solar CO_2 methane reforming. • A joint inversion method was developed to obtain thermochemical reaction parameters. • Results can be a guidance for the solar driven CO_2 methane reforming application.

    sites in the formation of benzene. With the bifunctional Pt-Al{sub 2}O{sub 3}-Cl catalysts, an increase of the acidity is also correlated to a strong increase of the benzene formation rate, while ethylbenzene and toluene formation rates are not affected. The introduction of Sn in this previous catalyst leads from one hand, to a decrease of the global activity and, to the other hand, when Sn content is higher than 0,1 wt% to a decrease of the formation of benzene. This latter decrease could be attributed to a modification of the Broensted acid sites through the Sn atoms interacting with the support. The studies performed on model monofunctional and bifunctional catalysts allowed us to conclude that on bifunctional catalysts, toluene and ethylbenzene are formed on metallic sites by hydrogenolysis while benzene comes from the cracking of n-propylbenzene through isopropylbenzene formation on strong Broensted acid sites. From these studies new ways for reforming catalysts preparation could be considered to limit the benzene content in the reformate and particularly, the limitation as far as possible, of the chlorine content, and may be the use of more adequate tin precursor.

    Full Text Available Le réchauffement climatique, la pauvreté ou la menace d’une catastrophe nucléaire comptent parmi les défis majeurs auxquels l’humanité se doit de faire face collectivement en ce début de 21e siècle. Malgré la gravité et l’urgence de la situation, les moyens dont nous disposons pour résoudre de tels problèmes demeurent limités et incomplets. Il est dès lors non seulement essentiel mais aussi urgent de penser comment faire face à de tels enjeux globaux. Les solutions passent par des mécanismes de gouvernance globale et se doivent de répondre aux exigences de solidarité, de démocratie, de justice sociale et d’efficacité politique. Il s’agit notamment d’assurer à chaque personne la possibilité d’influencer les conditions sociales qui façonnent sa vie. Il est donc encore possible d’agir sur le cours des choses, mais si aucune réponse n’est rapidement apportée à ces défis majeurs, le futur de l’humanité risque d’être compromis.Global warming, poverty and the threat of nuclear catastrophe are among the major challenges humanity has to face collectively in this early 21st century. In spite of the seriousness and the urgency of the situation, the means at our disposal to solve such problems remain limited and incomplete. It is therefore not only essential but also urgent to think about how to face these growing global challenges. It requires new mechanisms of global governance and taking steps toward solidarity, democracy, justice and policy effectiveness. Among these key issues is the need to ensure the possibility for each person to influence the social conditions that shape his or her life. Thus, there is still hope that the vital task of reframing global governance may be pursued with an increasing sense of urgency. If this does not happen, the very future of humanity is at risk.

    In developed and developing countries, the EIA (Environmental Impact Assessment) is becoming mandatory for the approval of Industrial projects and projects of Environmental hazards. The approving authority of each country has its own guidelines to get projects approved and make project proponents responsible to submit Environmental Impact Statement for the its detailed assessment. In this paper authors have studied an existing EIA Global guidelines and its evaluation process of altogether 40 countries from four continents, Asia, Pacific/Middle East, Europe, Australia and America/Canada. This evaluation process is recorded in the tabulation form and it has been formulated stage wise in which stage one highlights the inception of EIA guidelines of each country and stage two and three gives implementation process. The inception stage of guidelines gives an idea that when EIA was started and an implementation stages provide all information that when EIA become a part of legislation that provide an opportunity to the reader to understand the decision making process for project approvals. The main objective of writing EIA guidelines is to monitor the sustain ability of various types of the projects under different sectoral guidelines, therefore Projects related with different Sectors have been chosen and a detailed record in tabulation form gives an idea to understand the interaction of these guidelines. To make this paper more comprehensive, authors have gone thorough the sectoral guidelines of altogether 64 countries and studied 21 sector oriented project fields. These are of Agriculture/Irrigation, Biodiversity, Coastal/Marine, Community Participation, Extractive industries, Fisheries, Forestry, Hazard Risk, Health, Human settlement, Industry, Multi sectorial, Ports and Harbors, Power, refugees/resettlement, Social, Strategies/Planning, Tourism/Recreational, transportation, Waste Pollution and Wetlands/Water resources.

  17. Radiant non-catalytic recuperative reformer

    Energy Technology Data Exchange (ETDEWEB)

    Khinkis, Mark J.; Kozlov, Aleksandr P.

    2017-10-31

    A radiant, non-catalytic recuperative reformer has a flue gas flow path for conducting hot exhaust gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is positioned adjacent to the flue gas flow path to permit heat transfer from the hot exhaust gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, a portion of the reforming mixture flow path is positioned outside of flue gas flow path for a relatively large residence time.

    2006-01-01

    In this paper, a new design methodology and process is proposed for small scale pure hydrogen production capable of serving energy markets ranging from distributed generation to vehicular refuelling. The system was designed for producing 7 Nm 3 /hr pure hydrogen (purity of ≤ 1 ppm CO dry), yielding 10 kWe net power from a fuel cell system with an overall parasitic power loss ≤ 10 %. The discussion of this process includes a detailed description of the design methodology and operational results of the catalytic converter, the hydrogen purification system and the fuel cell system. This paper will discuss the design methodology of the overall system, as well as the specific design of the catalytic converter, the catalysts used within, and the hydrogen purification system. It will also report the system performance including gas purity, recovery rate, overall hydrogen production efficiencies, and electrical efficiencies during fuel cell operation. (authors)

  3. A Matter of Time: Enacting the Exclusion of Onshore Refugee Applicants through the Reform and Acceleration of Refugee Determination Processes

    2016-03-01

    Full Text Available State-based processes for determining refugee claims are crucial sites of inclusion or exclusion for onshore refugee applicants. This paper argues that cultures of disbelief and exclusion towards onshore refugee applicants are increasingly being enacted indirectly, via procedural reforms to Refugee Status Determination (RSD, which limit the ability of applicants to establish and articulate their claims. Focusing on Australia and Canada, this paper tracks the acceleration and truncation of RSD procedures, which first reflect and then frequently achieve the exclusion of onshore applicants. Two sets of reforms in particular have profoundly limited the terms on which applicants may present their claims. In Canada, this occurred as the result of a major overhaul of RSD that took place in December 2012. In Australia, the policy of ‘enhanced screening’ of applicants achieves the immediate screening-out of certain claims from the Australian determination system. Alongside analysing these reforms as a means of exclusion, this paper argues that the new procedures most disadvantage applicants making claims on the basis of gender-related persecution. Los procesos estatales para resolver las concesiones de asilo son situaciones cruciales para la inclusión o exclusión de los solicitantes de asilo una vez están en el territorio de acogida. Este artículo defiende que cada vez más, se está promulgando indirectamente la cultura de la desconfianza y exclusión hacia los solicitantes de asilo, a través de reformas procesuales de la Determinación del Estatus de Refugiado (DER, lo que limita la capacidad de los solicitantes para establecer y articular sus demandas de asilo. Centrándose en Australia y Canadá, este artículo realiza un seguimiento de la aceleración y el truncamiento de los procedimientos de DER que primero reflejan y después a menudo consiguen la exclusión de los solicitantes en el propio territorio de acogida.

    Hydrogen has a significant future potential as an alternative energy source for the transportation sector as well as in residential homes and offices, H 2 in fuel cell power systems provides an alternative to direct fossil fuel and biomass combustion based technologies and offer the possibility for a significant reduction in greenhouse gas emission based on improved H 2 yield per unit of fossil fuel and biomass, compatibility with renewable energies and motivation to convert to a H 2 -based energy economy. Several practical techniques for H 2 production to service H 2 refuelling stations as well as homes and offices, all of which need to be located at the end of the energy distribution network, include: (1) the carbon dioxide reforming of natural gas; (2) reforming of gasoline; (3) reforming of crude ethanol. Locating the H 2 production at the end of the energy distribution network solves the well-known problems of metal fatigue and high cost of H 2 compression for long distance transportation if H 2 is produced in a large centralized plant. In addition, the ratification of the Kyoto Protocol and the need to reduce emissions of CO 2 to the atmosphere has prompted the capture and utilization of the CO 2 produced from the reforming process. In this research: (1) new efficient catalysts for each reforming process was developed; (2) a new efficient catalyst for our version of the water gas shift reaction to convert carbon monoxide to carbon dioxide was developed; (3) a new membrane separation process for production of high purity, fuel cell-grade H 2 was designed; (4) a numerical model for optimum process design and optimum utilization of resources both at the laboratory and industrial scales was developed; (5) various processes for CO 2 capture were investigated experimentally in order to achieve a net improvement in the absorption process; (6) the utilization of captured CO 2 for enhanced oil recovery and/or storage in an aging oil field were investigated; (7

  5. System requirements of diesel reforming for the SOFC

    Diesel fuels are currently a very attractive source of hydrogen due to the global infrastructure for production and distribution that exists today. In order to extract the hydrogen, the hydrocarbon molecules must be chemically reformed into manageable, hydrogen-rich product gases that can be directly used in electrochemical energy conversion devices such as fuel cells. High temperature fuel cells are particularly attractive for diesel-fuelled systems due to the possibility of thermal integration with the high temperature reformer. The methods available for diesel fuel processing are: Steam Reforming, Partial Oxidation, and Auto-Thermal Reforming. The latter two methods introduce air into the process in order to cause exothermic oxidation reactions, which complement the endothermic heating requirement of the reforming reactions. This helps to achieve the high temperature required, but also introduces nitrogen, which can yield unwanted NO x emissions. The components of the reformer should include: an injection system to mix and vaporize the diesel fuel and steam while avoiding the formation of carbon deposits inside the reactor; a temperature and heat management system; and a method of sulphur removal. This presentation will discuss the operating conditions and design requirements of a diesel fuel processor for a solid oxide fuel cell (SOFC) system. (author)

    From 2007 on, the World Health Organisation (WHO) has been revising its diagnostic manual, the International Statistical Classification of Diseases and Related Health Problems (ICD), with approval of ICD-11 due in 2018. The ICD revision has prompted debates on diagnostic classifications related to gender diversity and gender development processes, and specifically on the 'Gender incongruence of childhood' (GIC) code. These debates have taken place at a time an emergent trans depathologisation movement is becoming increasingly international, and regional and international human rights bodies are recognising gender identity as a source of discrimination. With reference to the history of diagnostic classification of gender diversity in childhood, this paper conducts a literature review of academic, activist and institutional documents related to the current discussion on the merits of retaining or abandoning the GIC code. Within this broader discussion, the paper reviews in more detail recent publications arguing for the abandonment of this diagnostic code drawing upon clinical, bioethical and human rights perspectives. The review indicates that gender diverse children engaged in exploring their gender identity and expression do not benefit from diagnosis. Instead they benefit from support from their families, their schools and from society more broadly.

    level rise and fall cycles, and may be linked to strengthened upwelling currents. With the return to more oligotrophic conditions during the late Barremian, photozoan, Urgonian-type communities took up again. Their development has been abruptly stopped at the end of the early Aptian by a major emersion phase. The subsequent drowning is documented in various peritethyan areas. This initial crisis is followed by three other drowning phases that ultimately led to the replacement of shallow ecosystems by a deeper marine sedimentation in the Cenomanian. This long-term trend in the evolution of the Helvetic carbonate platform and of other peritethyan ecosystems may have been driven by more global phenomena. In particular, the progressive opening of the northern and equatorial Atlantic may have impacted sea level by creating new oceanic basins. The emplacement of submarine volcanic plateaus may have triggered sea level rise and fertilized deep oceanic waters through hydrothermal processes. Drowning unconformities thus record the interplay of local with long-term processes, and constitute regional sedimentary archives of global phenomena.

  9. Global Optimization Employing Gaussian Process-Based Bayesian Surrogates

    2018-03-01

    Full Text Available The simulation of complex physics models may lead to enormous computer running times. Since the simulations are expensive it is necessary to exploit the computational budget in the best possible manner. If for a few input parameter settings an output data set has been acquired, one could be interested in taking these data as a basis for finding an extremum and possibly an input parameter set for further computer simulations to determine it—a task which belongs to the realm of global optimization. Within the Bayesian framework we utilize Gaussian processes for the creation of a surrogate model function adjusted self-consistently via hyperparameters to represent the data. Although the probability distribution of the hyperparameters may be widely spread over phase space, we make the assumption that only the use of their expectation values is sufficient. While this shortcut facilitates a quickly accessible surrogate, it is somewhat justified by the fact that we are not interested in a full representation of the model by the surrogate but to reveal its maximum. To accomplish this the surrogate is fed to a utility function whose extremum determines the new parameter set for the next data point to obtain. Moreover, we propose to alternate between two utility functions—expected improvement and maximum variance—in order to avoid the drawbacks of each. Subsequent data points are drawn from the model function until the procedure either remains in the points found or the surrogate model does not change with the iteration. The procedure is applied to mock data in one and two dimensions in order to demonstrate proof of principle of the proposed approach.

    Morrison argued that demography, economy, and technology drive the evolution of industries from a formative first-generation state ("First Curve") to a radically different way of doing things ("Second Curve") that is marked by new skills, strategies, and partners. The current health-reform movement in the United States reflects these three key evolutionary trends: surging medical needs of an aging population, dramatic expansion of Medicare spending, and care delivery systems optimized through powerful information technology. Successful transition from a formative first-generation state (First Curve) to a radically different way of doing things (Second Curve) will require new skills, strategies, and partners. In a new world that is value-driven, community-centric (versus hospital-centric), and prevention-focused, orthopaedic surgeons and health-care administrators must form new alliances to reduce the cost of care and improve durable outcomes for musculoskeletal problems. The greatest barrier to success in the Second Curve stems not from lack of empirical support for integrated models of care, but rather from resistance by those who would execute them. Porter's five forces of competitive strategy and the behavioral analysis of change provide insights into the predictable forms of resistance that undermine clinical and economic success in the new environment of care. This paper analyzes the components that will differentiate orthopaedic care provision for the Second Curve. It also provides recommendations for future-focused orthopaedic surgery and health-care administrative leaders to consider as they design newly adaptive, mutually reinforcing, and economically viable musculoskeletal care processes that drive the level of orthopaedic care that our nation deserves-at a cost that it can afford.

    The future structure surrounding fuel choice in power generation sector should be understood how to evaluate actual and potential merit and demerit both in economic and environmental aspects on nuclear power generation. That is i.e. nuclear can be understood as superior power source without GHGs and on the other hand, as unfavorable power source which might cause some critical dangers due to its hazardous radioactive nuclear waste. On this specific characteristic, this theme on fuel choice surrounding nuclear in power generation sector could be understood as a highly cultural problem as much as economic and political one. For instance, we can observe quite opposite direction with each other on nuclear power development in European countries like France and Finland on one hand and Germany and Sweden on the other hand. Looking at Asian countries, we also observe the very reality of high economic growth with rapid growth of electricity demand like China. What on earth, is it really possible without nuclear power source for such gigantic countries. I will develop my personal idea on nuclear power source based on Japanese experience towards successfully managing nuclear power technologies in the world, consisting of developing countries with growing economies and of advanced ones with rather matured nuclear technology under the pressure of environmentally restricted world order. My basic view point to discuss nuclear power problem has, conclusionally speaking, several aspects; The first one is in the relation with deregulation or liberalization of electricity market, which has been undergoing among such developed countries as OECD member countries i.e. USA, EU, Japan and other countries. Deregulation or liberalization of electricity market seems to be the inevitable process towards more matured market economy among developed countries group, and that process inevitably forces management of power companies towards more near sighted attitude if those companies are

    Negative moods have been associated with a tendency to prioritise local details in visual processing. The current study investigated the relation between depression and visual processing using the Navon task, a standard task of local and global processing. In the Navon task, global stimuli are presented that are made up of many local parts, and the participants are instructed to report the identity of either a global or a local target shape. Participants with a low self-reported level of depression showed evidence of the expected global processing bias, and were significantly faster at responding to the global, compared with the local level. By contrast, no such difference was observed in participants with high levels of depression. The reduction of the global bias associated with high levels of depression was only observed in the overall speed of responses to global (versus local) targets, and not in the level of interference produced by the global (versus local) distractors. These results are in line with recent findings of a dissociation between local/global processing bias and interference from local/global distractors, and support the claim that depression is associated with a reduction in the tendency to prioritise global-level processing.

    Highlights: • A biogas reforming and fuel cell integrated process is considered. • Energy and exergy analyses of the integrated process are performed. • Increasing the nickel oxide-to-biogas ratio decreases the exergy efficiency. • The exergy destruction of the fuel cell increases with increasing cell temperature. • The exergy efficiency of the process is improved when heat integration is applied. - Abstract: A biogas sorption-enhanced chemical looping reforming process integrated with a high-temperature proton exchange membrane fuel cell is analyzed. Modeling of such an integrated process is performed by using a flowsheet simulator (Aspen plus). The exergy analysis is performed to evaluate the energy utilization efficiency of each unit and that of the integrated process. The effect of steam and nickel oxide to biogas ratios on the exergetic performance of the stand-alone biogas sorption-enhanced chemical looping reforming process is investigated. The total exergy destruction increases as the steam or nickel oxide to biogas ratio increases. The main exergy destruction is found at the air reactor. For the high-temperature proton exchange membrane fuel cell, the main exergy destruction is found at the cathode. The total exergy destruction increases when cell temperature increases, whereas the inverse effect is found when the current density is considered as a key parameter. Regarding the exergy efficiency, the results show opposite trend to the exergy destruction. The heat integration analysis is performed to improve the exergetic performance. It is found that the integrated process including the heat integration system can improve the exergy destruction and exergy efficiency of 48% and 60%, respectively.

    Palladium-based catalytic membrane reactors (CMRs) effectively remove H₂ to induce higher conversions in methane steam reforming (MSR) and water-gas-shift reactions (WGS). Within such a context, this work evaluates the technical performance of a novel CMR, which utilizes two catalysts in series, rather than one. In the process system under consideration, the first catalyst, confined within the shell side of the reactor, reforms methane with water yielding H₂, CO and CO₂. After reforming is completed, a second catalyst, positioned in series, reacts with CO and water through the WGS reaction yielding pure H₂O, CO₂ and H₂. A tubular composite asymmetric Pd/Au/Pd membrane is situated throughout the reactor to continuously remove the produced H₂ and induce higher methane and CO conversions while yielding ultrapure H₂ and compressed CO₂ ready for dehydration. Experimental results involving (i) a conventional packed bed reactor packed (PBR) for MSR, (ii) a PBR with five layers of two catalysts in series and (iii) a CMR with two layers of two catalysts in series are comparatively assessed and thoroughly characterized. Furthermore, a comprehensive 2D computational fluid dynamics (CFD) model was developed to explore further the features of the proposed configuration. The reaction was studied at different process intensification-relevant conditions, such as space velocities, temperatures, pressures and initial feed gas composition. Finally, it is demonstrated that the above CMR module, which was operated for 600 h, displays quite high H₂ permeance and purity, high CH₄ conversion levels and reduced CO yields.

    2017-12-01

    Based on the principle of Gibbs free energy minimization, the thermodynamic analysis on the CO2 conversion processes of dry reforming of methane for H2 and CO2 hydrogenation to dimethyl ether was carried out. The composition of the reaction system was determined on the basis of reaction mechanism. The effects of reaction temperature, pressure and raw material composition on the equilibrium conversion and the selectivity of products were analyzed. The results show that high temperature, low pressure, CO2/CH4 molar ratio of 1.0-1.5 and appropriate amount of oxygen are beneficial to the dry reforming of methane. For CO2 hydrogenation to dimethyl ether, low temperature, high pressure, the appropriate H2/CO2 and the proper CO addition in feed are favorable. The calculated results are compared with the relevant studies, indicating that industrial catalytic technology needs further improvement.

    The ability to generate a suitable finite element mesh in an automatic fashion is becoming the key to being able to automate the entire engineering analysis process. However, placing an all-hexahedron mesh in a general three-dimensional body continues to be an elusive goal. The approach investigated in this research is fundamentally different from any other that is known of by the authors. A physical analogy viewpoint is used to formulate the actual meshing problem which constructs a global mathematical description of the problem. The analogy used was that of minimizing the electrical potential of a system charged particles within a charged domain. The particles in the presented analogy represent duals to mesh elements (i.e., quads or hexes). Particle movement is governed by a mathematical functional which accounts for inter-particles repulsive, attractive and alignment forces. This functional is minimized to find the optimal location and orientation of each particle. After the particles are connected a mesh can be easily resolved. The mathematical description for this problem is as easy to formulate in three-dimensions as it is in two- or one-dimensions. The meshing algorithm was developed within CoMeT. It can solve the two-dimensional meshing problem for convex and concave geometries in a purely automated fashion. Investigation of the robustness of the technique has shown a success rate of approximately 99% for the two-dimensional geometries tested. Run times to mesh a 100 element complex geometry were typically in the 10 minute range. Efficiency of the technique is still an issue that needs to be addressed. Performance is an issue that is critical for most engineers generating meshes. It was not for this project. The primary focus of this work was to investigate and evaluate a meshing algorithm/philosophy with efficiency issues being secondary. The algorithm was also extended to mesh three-dimensional geometries. Unfortunately, only simple geometries were tested

    Online networks can serve as a platform to diffuse policy innovations and enhance global health governance. This study focuses on how shifts in global health governance may influence related online networks. We compare social network metrics (average degree centrality [AVGD], density [D] and clustering coefficient [CC]) of Globalink, an online network of tobacco control advocates, across three eras in global tobacco control governance; pre-Framework Convention on Tobacco Control (FCTC) policy transfer (1992-1998), global regime formation through the FCTC negotiations (1999-2005), and philanthropic funding through the Bloomberg Initiative (2006-2012). Prior to 1999, Globalink was driven by a handful of high-income countries (AVGD=1.908 D=0.030, CC=0.215). The FCTC negotiations (1999-2005) corresponded with a rapid uptick in the number of countries represented within Globalink and new members were most often brought into the network through relationships with regional neighbors (AVGD=2.824, D=0.021, CC=0.253). Between 2006 and 2012, the centrality of the US in the network increases significantly (AVGD=3.414, D=0.023, CC=0.310). The findings suggest that global institutionalization through WHO, as with the FCTC, can lead to the rapid growth of decentralized online networks. Alternatively, private initiatives, such as the Bloomberg Initiative, can lead to clustering in which a single source of information gains increasing influence over an online network.

Outros documentos como a Declaração Mundial sobre Educação Superior, 1998, representam marco referencial das reformas a que se refere este texto. Em sua essência, os documentos europeus vinculam o movimento reformista da educação superior às necessidades contextualizadas pelo padrão de globalização da economia. São articulações que têm como base o incentivo à competitividade, mobilidade discente, adaptação ao mercado de trabalho. No Brasil, em que sentido é possível situar os reflexos desse movimento? Na busca desse entendimento, focalizamos o movimento empreendido pelo Ministério da Educação para discutir a reforma universitária para o país, em especial destacamos o Seminário Internacional Universidade XXI e a Declaração de Brasília. Resguardadas as especificidades de cada situação, vislumbramos refletir sobre possíveis intersecções dos movimentos reformistas na educação superior contemporânea.

    Full Text Available La primacía de los rasgos globales de una forma visual sobre los locales, o viceversa, es todavía una cuestión sin resolver. Algunos autores han señalado que la precedencia global sucede cuando se iguala la excentricidad de los niveles global y local mediante la utilización de estímulos concéntricos. Sin embargo, otras investigaciones con patrones visuales similares han obtenido precedencia local. El presente trabajo incluye dos experimentos planificados para arrojar luz sobre la interpretación de estos resultados inconsistentes. En conjunto, se pretende analizar si la diferencia en la densidad estimular utilizada en los distintos experimentos o la diferencia en el tipo de tarea pueden ser hipótesis plausibles para explicar la obtención de los resultados contradictorios. En el primer experimento, bajo condiciones de atención selectiva y dividida, se incluye una tarea de detección de una figura-objetivo en el estímulo con un tiempo de exposición de 150 msg. y con estímulos concéntricos con mayor número de elementos locales que los empleados en experimentos previos (Blanca, López, Luna, Zalabardo y Rando, 2000; 2001. Los resultados apuntan a una ausencia de ventaja global o local y a una interferencia bidireccional para la condición de atención selectiva, y bidreccional pero asimétrica para la condición de atención dividida, siendo mayor la interferencia global. En el segundo experimento, se instruye a los sujetos para que indiquen la dirección, izquierda o derecha, de la apertura de un semicírculo en el nivel pertinente, según la condición de dirección de la atención. Los estímulos se presentan con un tiempo de exposición de 150 msg. o ilimitado. Los resultados muestran una ventaja global, tanto bajo condiciones de atención dividida como selectiva, la cual es independiente del tiempo de exposición del estímulo.

    2014-08-01

    Full Text Available In this study, the performance of several differently treated natural zeolites in a sequential pyrolysis and catalytic reforming of plastic materials i.e. polypropylene (PP and polystyrene (PS were investigated. The experiments were carried out on two stage reactor using semi-batch system. The samples were degraded at 500°C in the pyrolysis reactor and then reformed at 450°C in the catalytic reformer. The results show that the mordenite-type natural zeolites could be used as efficient catalysts for the conversion of PP and PS into liquid and gaseous fuel. The treatment of natural zeolites in HCl solution showed an increase of the surface area and the Si/Al ratio while nickel impregnation increased the activity of catalyst. As a result, liquid product was reduced while gaseous product was increased. For PP, the fraction of gasoline (C5-C12 increased in the presence of catalysts. Natural zeolite catalysts could also be used to decrease the heavy oil fraction (>C20. The gaseous products were found that propene was dominated in all conditions. For PS, propane and propene were the main components of gases in the presence of nickel impregnated natural zeolite catalyst. Propene was dominated in pyrolysis over natural zeolite catalyst. The high quality of gaseous product can be used as a fuel either for driving gas engines or for dual-fuel diesel engine.

    Jansen, G.; Knutson, B.J.; Niccoli, L.G.; Frank, D.D.

    1994-01-01

    Remediation of the Hanford waste tanks requires integration of chemical technologies and evaluation of alternatives from the perspective of the overall Hanford cleanup purpose. The use of Design/IDEF (R) logic to connect chemical process functions to the overall cleanup mission in the Hanford Strategic Analysis (HSA) and to Aspen Plus (R) process models can show the effect of each process step on global performance measures such as safety, cost, and public perception. This hybrid of chemical process analysis and systems engineering produces structured material balance flowsheets at any level of process aggregation within the HSA. Connectivity and consistent process and stream nomenclature are automatically transferred between detailed process models, the HSA top purpose, and the global material balance flowsheet evaluation. Applications to separation processes is demonstrated for a generic Truex-Sludge Wash flowsheet with many process options and for the aggregation of a Clean Option flowsheet from a detailed chemical process level to a global evaluation level

    Anxiety is a risk factor for disordered eating, but the mechanisms by which anxiety promotes disordered eating are poorly understood. One possibility is local versus global cognitive processing style, defined as a relative tendency to attend to details at the expense of the "big picture." Anxiety may narrow attention, in turn, enhancing local and/or compromising global processing. We examined relationships between global/local processing style, anxiety, and disordered eating behaviors in a transdiagnostic outpatient clinical sample. We hypothesized that local (vs. global) processing bias would mediate the relationship between anxiety and disordered eating behaviors. Ninety-three participants completed the eating disorder examination-questionnaire (EDE-Q), State-Trait Anxiety Inventory (STAI)-trait subscale, and the Navon task (a test of processing style in which large letters are composed of smaller letters both congruent and incongruent with the large letter). The sample was predominantly female (95%) with a mean age of 27.4 years (SD = 12.1 years). Binge eating, but not fasting, purging, or excessive exercise, was correlated with lower levels of global processing style. There was a significant indirect effect between anxiety and binge eating via reduced global level global/local processing. In individuals with disordered eating, being more generally anxious may encourage a detailed-oriented bias, preventing individuals from maintaining the bigger picture and making them more likely to engage in maladaptive behaviors (e.g., binge eating). © 2017 Wiley Periodicals, Inc.

At the same time in the context of globalization the place and role of international labor migration changes in the global economy system: migration becomes a means of promoting the globalization of countries and regions, the most important factor of demographic development and economic growth.

  3. Integration of Methane Steam Reforming and Water Gas Shift Reaction in a Pd/Au/Pd-Based Catalytic Membrane Reactor for Process Intensification

    Directory of Open Access Journals (Sweden)

    Bernardo Castro-Dominguez

    2016-09-01

    Full Text Available Palladium-based catalytic membrane reactors (CMRs effectively remove H2 to induce higher conversions in methane steam reforming (MSR and water-gas-shift reactions (WGS. Within such a context, this work evaluates the technical performance of a novel CMR, which utilizes two catalysts in series, rather than one. In the process system under consideration, the first catalyst, confined within the shell side of the reactor, reforms methane with water yielding H2, CO and CO2. After reforming is completed, a second catalyst, positioned in series, reacts with CO and water through the WGS reaction yielding pure H2O, CO2 and H2. A tubular composite asymmetric Pd/Au/Pd membrane is situated throughout the reactor to continuously remove the produced H2 and induce higher methane and CO conversions while yielding ultrapure H2 and compressed CO2 ready for dehydration. Experimental results involving (i a conventional packed bed reactor packed (PBR for MSR, (ii a PBR with five layers of two catalysts in series and (iii a CMR with two layers of two catalysts in series are comparatively assessed and thoroughly characterized. Furthermore, a comprehensive 2D computational fluid dynamics (CFD model was developed to explore further the features of the proposed configuration. The reaction was studied at different process intensification-relevant conditions, such as space velocities, temperatures, pressures and initial feed gas composition. Finally, it is demonstrated that the above CMR module, which was operated for 600 h, displays quite high H2 permeance and purity, high CH4 conversion levels and reduced CO yields.

    Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

    Black, Emily; Stevenson, Jennifer L; Bish, Joel P

    2017-08-01

    The global precedence effect is a phenomenon in which global aspects of visual and auditory stimuli are processed before local aspects. Individuals with musical experience perform better on all aspects of auditory tasks compared with individuals with less musical experience. The hemispheric lateralization of this auditory processing is less well-defined. The present study aimed to replicate the global precedence effect with auditory stimuli and to explore the lateralization of global and local auditory processing in individuals with differing levels of musical experience. A total of 38 college students completed an auditory-directed attention task while electroencephalography was recorded. Individuals with low musical experience responded significantly faster and more accurately in global trials than in local trials regardless of condition, and significantly faster and more accurately when pitches traveled in the same direction (compatible condition) than when pitches traveled in two different directions (incompatible condition) consistent with a global precedence effect. In contrast, individuals with high musical experience showed less of a global precedence effect with regards to accuracy, but not in terms of reaction time, suggesting an increased ability to overcome global bias. Further, a difference in P300 latency between hemispheres was observed. These findings provide a preliminary neurological framework for auditory processing of individuals with differing degrees of musical experience.

    Highlights: • PEMFC systems with a glycerol steam reformer for stationary application are studied. • Performance of HT-PEMFC and LT-PEMFC systems is compared. • HT-PEMFC system shows good performance over LT-PEMFC system at a high current density. • HT-PEMFC system with water gas shift reactor shows the highest system efficiency. • Heat integration can improve the efficiency of HT-PEMFC system. - Abstract: A high-temperature polymer electrolyte membrane fuel cell (HT-PEMFC) has a major advantage over a low-temperature polymer electrolyte fuel cell (LT-PEMFC) demonstrated by a tolerance to a higher CO content in the hydrogen feed and thus a simpler fuel processing. In this study, a direct comparison between the performance of HT-PEMFC and LT-PEMFC systems integrated with a glycerol steam reformer with and without a water gas shift reactor is shown. Under pure hydrogen operation, the LT-PEMFC performance is superior to the HT-PEMFC. However, the HT-PEMFC system shows good performance over the LT-PEMFC system when operated under high current density and high pressure (3 atm) and using the reformate gas derived from the glycerol processor as fuel. At high current density, the high concentration of CO is the major limitation for the operation of HT-PEMFC system without water gas shift reactor, whereas the LT-PEMFC suffers from CO poisoning and restricted oxygen mass transport. Considering the system efficiency with co-heat and power generation, the HT-PEMFC system with water gas shift reactor shows the highest overall system efficiency (approximately 60%) and therefore one of the most suitable technologies for stationary applications

    Full Text Available The rigidity of labour market has several important negative economic consequences: it stifles job creation, increases discrimination of those that it is actually aimed at protecting (young, women and the low-skilled, hurts the unemployed, slows down economic restructuring and damages its global competitiveness. But reforms are slow and often marked with disputes among partners in the collective bargaining process. Afraid of social security loss, unions usually oppose the reform, while governments usually give in to the union pressures and negative image of reform consequences created by unions and assisted by media. The characteristics of the labour market and labour market reform with respect to bargaining among power groups are examined both theoretically and empirically in the case of Slovenia.

    One of the active tectonic zones of Egypt located in Aswan, is characterized by regional basement rock uplift and regional faulting. In 1997, the African Regional Geodynamic Network was developed around the northern part of Lake Nasser, consists of 11 points, on both sides of the Lake. Its main goal is to study the geodynamical behavior around the northern part of the lake. The collected data were processed using the Bernese software version 5.0. From the velocity results, including also the African plate motion, it can be noticed that all stations of this network are moved to the northeast direction and it is typically the direction of the African plate motion.

    Information processing is generally biased toward global cues, often at the expense of local information. Equivocal extant data suggests that arousal states may accentuate either a local or global processing bias, at least partially dependent on the nature of the manipulation, task, and stimuli.

    2011-03-01

    A dynamic model of oxide Czochralski growth with weighing control has been developed for the first time. A time-dependent approach is used for the calculation of temperature fields in different parts of a crystallization set-up and convection patterns in a melt, while internal radiation in crystal is considered in a quasi-steady approximation. A special algorithm is developed for the calculation of displacement of a triple point and simulation of a crystal surface formation. To calculate variations in the heat generation, a model of weighing control with a commonly used PID regulator is applied. As an example, simulation of the growth process of gallium-gadolinium garnet (GGG) crystals starting from the stage of seeding is performed.

  2. Global land-atmosphere coupling associated with cold climate processes

    Dutra, Emanuel

    This dissertation constitutes an assessment of the role of cold processes, associated with snow cover, in controlling the land-atmosphere coupling. The work was based on model simulations, including offline simulations with the land surface model HTESSEL, and coupled atmosphere simulations with the EC-EARTH climate model. A revised snow scheme was developed and tested in HTESSEL and EC-EARTH. The snow scheme is currently operational at the European Centre for Medium-Range Weather Forecasts integrated forecast system, and in the default configuration of EC-EARTH. The improved representation of the snowpack dynamics in HTESSEL resulted in improvements in the near surface temperature simulations of EC-EARTH. The new snow scheme development was complemented with the option of multi-layer version that showed its potential in modeling thick snowpacks. A key process was the snow thermal insulation that led to significant improvements of the surface water and energy balance components. Similar findings were observed when coupling the snow scheme to lake ice, where lake ice duration was significantly improved. An assessment on the snow cover sensitivity to horizontal resolution, parameterizations and atmospheric forcing within HTESSEL highlighted the role of the atmospheric forcing accuracy and snowpack parameterizations in detriment of horizontal resolution over flat regions. A set of experiments with and without free snow evolution was carried out with EC-EARTH to assess the impact of the interannual variability of snow cover on near surface and soil temperatures. It was found that snow cover interannual variability explained up to 60% of the total interannual variability of near surface temperature over snow covered regions. Although these findings are model dependent, the results showed consistency with previously published work. Furthermore, the detailed validation of the snow dynamics simulations in HTESSEL and EC-EARTH guarantees consistency of the results.

  3. Attentional selection of relative SF mediates global versus local processing: evidence from EEG.

    Previous research on functional hemispheric differences in visual processing has associated global perception with low spatial frequency (LSF) processing biases of the right hemisphere (RH) and local perception with high spatial frequency (HSF) processing biases of the left hemisphere (LH). The Double Filtering by Frequency (DFF) theory expanded this hypothesis by proposing that visual attention selects and is directed to relatively LSFs by the RH and relatively HSFs by the LH, suggesting a direct causal relationship between SF selection and global versus local perception. We tested this idea in the current experiment by comparing activity in the EEG recorded at posterior right and posterior left hemisphere sites while participants' attention was directed to global or local levels of processing after selection of relatively LSFs versus HSFs in a previous stimulus. Hemispheric asymmetry in the alpha band (8-12 Hz) during preparation for global versus local processing was modulated by the selected SF. In contrast, preparatory activity associated with selection of SF was not modulated by the previously attended level (global/local). These results support the DFF theory that top-down attentional selection of SF mediates global and local processing.

  4. Global Production Planning Process considering the Supply Risk of Overseas Manufacturing Sites

    2015-01-01

    Full Text Available Although global manufacturers can produce most of their final products in local plants, they need to source components or parts from desirable overseas manufacturing partners at low cost in order to fulfill customer orders. In this global manufacturing environment, capacity information for planning is usually imprecise owing to the various risks of overseas plants (e.g., foreign governments’ policies and labor stability. It is therefore not easy for decision-makers to generate a global production plan showing the production amounts at local plants and overseas manufacturing facilities operated by manufacturing partners. In this paper, we present a new global production planning process considering the supply risk of overseas manufacturing sites. First, local experts estimate the supply capacity of an overseas plant using their judgment to determine when the risk could occur and how large the risk impact would be. Next, we run a global production planning model with the estimated supply capacities. The proposed process systematically adopts the qualitative judgments of local experts in the global production planning process and thus can provide companies with a realistic global production plan. We demonstrate the applicability of the proposed process with a real world case.

    The worldwide LPG industry continues to expand faster than the petroleum industry -- 4%/year for LPG vs. 2%/year for petroleum in 1995 and less than 1%/year in the early 1990s. This rapid expansion of LPG markets is occurring in virtually every region of the world, including such developing countries as China. The Far East is the focus of much of the LPG industry's attention, but many opportunities exist in other regions such as the Indian subcontinent, Southeast Asia, and Latin America. The investment climate is improving in all phases of downstream LPG marketing, including terminaling, storage, and wholesale and retail distribution. The world LPG supply/demand balance has been relatively tight since the Gulf War and should remain so. Base demand (the portion of demand that is not highly price-sensitive) is expanding more rapidly than supplies. As a result, the proportion of total LPG supplies available for price-sensitive petrochemical feedstock markets is declining, at least in the short term. The paper discusses importers, price patterns, world LPG demand, world LPG supply, US NGL supply, US gas processing, ethane and propane supply, butane, isobutane, and natural gasoline supply, and US NGL demand

    Desert dust, both modern and ancient, is a critical component of the Earth system. Atmospheric dust has important effects on climate by changing the atmospheric radiation budget, while deposited dust influences biogeochemical cycles in the oceans and on land. Dust deposited on snow and ice decreases its albedo, allowing more light to be trapped at the surface, thus increasing the rate of melt and influencing energy budgets and river discharge. In the human realm, dust contributes to the transport of allergens and pathogens and when inhaled can cause or aggravate respiratory diseases. Dust storms also represent a significant hazard to road and air travel. Because it affects so many Earth processes, dust is studied from a variety of perspectives and at multiple scales, with various disciplines examining emissions for different purposes using disparate strategies. Thus, the range of objectives in studying dust, as well as experimental approaches and results, has not yet been systematically integrated. Key research questions surrounding the production and sources of dust could benefit from improved collaboration among different research communities. These questions involve the origins of dust, factors that influence dust production and emission, and methods through which dust can be monitored. ?? Author(s) 2011.

    1994-12-01

    The nearby grand design spiral galaxy, M 51, is an obvious proving ground for studies of spiral structure and large scale star formation processes. New near--infrared observations of M 51 made with COB (Cryogenic Optical Bench) on the Kitt Peak 1.3m allow us to examine the stellar distribution and the young star formation regions as well as probe regions of high extinction such as dust lanes. We also present an analysis of the kinematics of the ionized gas observed with the Maryland--Caltech Imaging Fabry Perot. The color information we derive from the near--infrared bands provides a more accurate tracer of extinction than optical observations. We find that the dust extinction and CO emission in the arms are well correlated. Our kinematic data show unambiguously that these dense gas concentrations are associated with kinematic perturbations. In the inner disk, these perturbations are seen to be consistent with the streaming motions predicted by classical density wave theory. The dust lanes, and presumably the molecular arms, form a narrow ridge that matches these velocity perturbations wherever the viewing angle is appropriate. This interpretation requires that the corotation radius be inward of the outer tidal arms. The outer tidal arms however show streaming velocities of the sign that would be expected interior to the corotation point. This can be reconciled if the outer arms are part of a second spiral pattern, most likely due to the interaction with the companion NGC 5195. The near--infrared observations also show emission from the massive star forming regions. These observations are less affected by extinction than optical observations of H II regions and show clearly that the sites of massive star formation are correlated with but downstream from the concentrations of dense molecular material. This provides clear evidence that the ISM has been organized by the streaming motions which have in turn triggered massive star formation.

    Previous studies of global-local processing in autism spectrum disorders (ASDs) have indicated mixed findings, with some evidence of a local processing bias, or preference for detail-level information, and other results suggesting typical global advantage, or preference for the whole or gestalt. Findings resulting from this paradigm have been used to argue for or against a detail focused processing bias in ASDs, and thus have important theoretical implications. We applied Systems Factorial Technology, and the associated Double Factorial Paradigm (both defined in the text), to examine information processing characteristics during a divided attention global-local task in high-functioning individuals with an ASD and typically developing controls. Group data revealed global advantage for both groups, contrary to some current theories of ASDs. Information processing models applied to each participant revealed that task performance, although showing no differences at the group level, was supported by different cognitive mechanisms in ASD participants compared to controls. All control participants demonstrated inhibitory parallel processing and the majority demonstrated a minimum-time stopping rule. In contrast, ASD participants showed exhaustive parallel processing with mild facilitatory interactions between global and local information. Thus our results indicate fundamental differences in the stopping rules and channel dependencies in individuals with an ASD.

  11. Effects of global and local contexts on chord processing: An ERP study.

    In real life, the processing of an incoming event is continuously influenced by prior information at multiple timescales. The present study investigated how harmonic contexts at both local and global levels influence the processing of an incoming chord in an event-related potentials experiment. Chord sequences containing two phrases were presented to musically trained listeners, with the last critical chord either harmonically related or less related to its preceding context at local and/or global levels. ERPs data showed an ERAN-like effect for local context in early time window and a N5-like component for later interaction between the local context and global context. These results suggest that both the local and global contexts influence the processing of an incoming music event, and the local effect happens earlier than the global. Moreover, the interaction between the local context and global context in N5 may suggest that music syntactic integration at local level takes place prior to the integration at global level.

    Understanding modern and historical global changes requires interdisciplinary knowledge of the physical and life sciences. The Understanding Global Change website from the UC Museum of Paleontology will use a focal infographic that unifies diverse content often taught in separate K-12 science units. This visualization tool provides scientists with a structure for presenting research within the broad context of global change, and supports educators with a framework for teaching and assessing student understanding of complex global change processes. This new approach to teaching the science of global change is currently being piloted and refined based on feedback from educators and scientists in anticipation of a 2016 website launch. Global change concepts are categorized within the infographic as causes of global change (e.g., burning of fossil fuels, volcanism), ongoing Earth system processes (e.g., ocean circulation, the greenhouse effect), and the changes scientists measure in Earth's physical and biological systems (e.g., temperature, extinctions/radiations). The infographic will appear on all website content pages and provides a template for the creation of flowcharts, which are conceptual models that allow teachers and students to visualize the interdependencies and feedbacks among processes in the atmosphere, hydrosphere, biosphere, and geosphere. The development of this resource is timely given that the newly adopted Next Generation Science Standards emphasize cross-cutting concepts, including model building, and Earth system science. Flowchart activities will be available on the website to scaffold inquiry-based lessons, determine student preconceptions, and assess student content knowledge. The infographic has already served as a learning and evaluation tool during professional development workshops at UC Berkeley, Stanford University, and the Smithsonian National Museum of Natural History. At these workshops, scientists and educators used the infographic

    2017-01-01

    Even when the body is stationary, the whole retinal image is always in motion by fixational eye movements and saccades that move the eye between fixation points. Accumulating evidence indicates that the brain is equipped with specific mechanisms for compensating for the global motion induced by these eye movements. However, it is not yet fully understood how the retina processes global motion images during eye movements. Here we show that global motion images evoke novel coordinated firing in retinal ganglion cells (GCs). We simultaneously recorded the firing of GCs in the goldfish isolated retina using a multi-electrode array, and classified each GC based on the temporal profile of its receptive field (RF). A moving target that accompanied the global motion (simulating a saccade following a period of fixational eye movements) modulated the RF properties and evoked synchronized and correlated firing among local clusters of the specific GCs. Our findings provide a novel concept for retinal information processing during eye movements.

    Improving the octane number of the aromatics' compounds has always been an important matter in refineries and lots of investigations have been made concerning this issue. In this study, an axial-flow spherical packed-bed reactor (AF-SPBR) is considered for naphtha reforming process in the presence of catalyst deactivation. Model equations are solved by the orthogonal collocation method. The AF-SPBR results are compared with the plant data of a conventional tubular packed-bed reactor (TR). The effects of some important parameters such as pressure and temperature on aromatic and hydrogen production rates and catalyst activity have been investigated. Higher production rates of aromatics can successfully be achieved in this novel reactor. Moreover, results show the capability of flow augmentation in the proposed configuration in comparison with the TR. This study shows the superiority of AF-SPBR configuration to the conventional types. (author)

    The link between psychosocial stress and cognitive function is complex, and previous studies have indicated that it may be mediated by processing speed. Therefore, the main aim of this study was to examine whether processing speed mediates the association between psychosocial stress and global cognition in older adults. Moreover, the moderating role of gender in this model is examined as well. The study included 2322 community-dwelling older adults in Malaysia who were randomly selected through a multistage proportional cluster random sampling technique. Global cognition construct was measured by the Mini-Mental State Examination and Montreal Cognitive Assessment; psychosocial stress construct was measured by perceived stress, depression, loneliness, and neuroticism; and processing speed was assessed by the Digit Symbol Substitution Test. Structural equation modelling was used to analyze the mediation and moderation tests. Processing speed was found to partially mediate the relationship between psychosocial stress and global cognition (β in the direct model = -0.15, P cognition was found to be significant in men only, whereas the association between processing speed and global cognition was significant in men and women. Psychosocial stress may increase the likelihood that older adults will experience poor processing capacity, which could reduce their higher level cognition. Results indicate that there is a need to develop processing capacity intervention programmes for psychologically distressed older adults to prevent them from suffering cognitive decline. © 2018 Japanese Psychogeriatric Society.

    Aqueous phase reforming is useful for processing oxygenated hydrocarbons to hydrogen and other more useful products. Current processing is hampered by the fact that oxide based catalysts are not stable under high temperature hydrothermal conditions. Silica in the form of structured MCM-41 is thermally a more stable support for Co and Ni than conventional high surface area amorphous silica but hydrothermal stability is not demonstrated. Carbon nanotube supports, in contrast, are highly stable under hydrothermal reaction conditions. In this project we show that carbon nanotubes are stable high activity/selectivity supports for the conversion of ethylene glycol to hydrogen.

    Body dysmorphic disorder (BDD) is characterized by distressing and often debilitating preoccupations with misperceived defects in appearance. Research suggests that aberrant visual processing may contribute to these misperceptions. This study used two tasks to probe global and local visual processing as well as set shifting in individuals with BDD. Eighteen unmedicated individuals with BDD and 17 non-clinical controls completed two global-local tasks. The embedded figures task requires participants to determine which of three complex figures contained a simpler figure embedded within it. The Navon task utilizes incongruent stimuli comprised of a large letter (global level) made up of smaller letters (local level). The outcome measures were response time and accuracy rate. On the embedded figures task, BDD individuals were slower and less accurate than controls. On the Navon task, BDD individuals processed both global and local stimuli slower and less accurately than controls, and there was a further decrement in performance when shifting attention between the different levels of stimuli. Worse insight correlated with poorer performance on both tasks. Taken together, these results suggest abnormal global and local processing for non-appearance related stimuli among BDD individuals, in addition to evidence of poor set-shifting abilities. Moreover, these abnormalities appear to relate to the important clinical variable of poor insight. Further research is needed to explore these abnormalities and elucidate their possible role in the development and/or persistence of BDD symptoms. PMID:24972487

    A multi-modal abnormality in the integration of parts and whole has been proposed to account for a bias toward local stimuli in individuals with autism (Frith, 1989; Mottron & Belleville, 1993). In the current experiment, we examined the utility of hierarchical models in characterising musical information processing in autistic individuals. Participants were 13 high-functioning individuals with autism and 13 individuals of normal intelligence matched on chronological age, nonverbal IQ, and laterality, and without musical experience. The task consisted of same-different judgements of pairs of melodies. Differential local and global processing was assessed by manipulating the level, local or global, at which modifications occurred. No deficit was found in the two measures of global processing. In contrast, the clinical group performed better than the comparison group in the detection of change in nontransposed, contour-preserved melodies that tap local processing. These findings confirm the existence of a "local bias" in music perception in individuals with autism, but challenge the notion that it is accounted for by a deficit in global music processing. The present study suggests that enhanced processing of elementary physical properties of incoming stimuli, as found previously in the visual modality, may also exist in the auditory modality.

    Full Text Available Globalization in the economy requires proper management of countries' financial resources as the regulation of international financial market is one of the most important tasks of the successful development of the world economy and individual national economies. The International Monetary Fund since the beginning of its creation was intended to regulate the financial situation in the post-war period in world space. In present conditions of information development of the world economic system the role and importance of international financial institutions are changing. Thus, the policies and activities of the IMF are increasingly criticized, that is substantiated and requires some restructuring and reforming areas of the Fund activity. During the research the basic aspects of IMF activities in 2015 have been analyzed and the suggestions for its further effective development have been presented. In particular, it is advisable to use the specific individual approach to the problems of particular economies and to view the sizes of quotas and their functional purposes that will allow to develop new funding mechanisms that are based on social and ecological needs of society. This, in turn, will reduce the impact of developed countries on the activities of the financial institution

    Full Text Available This paper reports on a mid-point evaluation of the Gauteng Primary Language and Mathematics Strategy (GPLMS, an innovative large-scale reform designed to improve learning outcomes. Using data from universal testing of all learners in 2008 on a provincial systemic evaluation, and data from the 2011 and 2012 Annual National Assessment (ANA test, this paper addresses the key research question, namely whether the GPLMS is effective in closing the gap between performing and underperforming schools. Given the evidence we have presented of an instrument effect, namely that various versions of the ANA may not be strictly comparable, no definitive conclusions can be drawn about the effectiveness of the GPLMS.

    'Full text:' Auto-thermal reformers are used popularly for fuel cell vehicle because they are compact and can start up quickly. On the other hand, steam reformers are used for stationary fuel cell power plant because they are good thermal efficiency. While, there are many cases using the auto- thermal reformer for stationary use with expectation of cost reduction in USA, as well. However, they are still insufficient for its durability, compactness and cost. We have been developing the new type of fuel processing system that is auto-thermal steam reformer (ATSR), which is hybrid of a conventional steam reformer (STR) and a conventional auto-thermal reformer (ATR). In this study, some proto-type of ATSR for field test were designed, tried manufacturing and tested performance and durability. And we have tried to operate with fuel cell stack to evaluate the system interface performance, that is, operability and controllability. (author)

  16. The impact of global nuclear mass model uncertainties on r-process abundance predictions

    Full Text Available Rapid neutron capture or ‘r-process’ nucleosynthesis may be responsible for half the production of heavy elements above iron on the periodic table. Masses are one of the most important nuclear physics ingredients that go into calculations of r-process nucleosynthesis as they enter into the calculations of reaction rates, decay rates, branching ratios and Q-values. We explore the impact of uncertainties in three nuclear mass models on r-process abundances by performing global monte carlo simulations. We show that root-mean-square (rms errors of current mass models are large so that current r-process predictions are insufficient in predicting features found in solar residuals and in r-process enhanced metal poor stars. We conclude that the reduction of global rms errors below 100 keV will allow for more robust r-process predictions.

    People with Autism Spectrum Disorder (ASD) are hypothesized to have poor high-level processing but superior low-level processing, causing impaired social recognition, and a focus on non-social stimulus contingencies. Biological motion perception provides an ideal domain to investigate exactly how ASD modulates the interaction between low and high-level processing, because it involves multiple processing stages, and carries many important social cues. We investigated individual differences among typically developing observers in biological motion processing, and whether such individual differences associate with the number of autistic traits. In Experiment 1, we found that individuals with fewer autistic traits were automatically and involuntarily attracted to global biological motion information, whereas individuals with more autistic traits did not show this pre-attentional distraction. We employed an action adaptation paradigm in the second study to show that individuals with more autistic traits were able to compensate for deficits in global processing with an increased involvement in local processing. Our findings can be interpreted within a predictive coding framework, which characterizes the functional relationship between local and global processing stages, and explains how these stages contribute to the perceptual difficulties associated with ASD.

    Interest in environmental issues and the magnitude of the environmental changes continues. One way to gain more understanding of the atmosphere is to make measurements on a global scale from space. The Earth Observation System is a series of new sensors to measure globally atmospheric parameters. Analysis of satellite data by developing algorithms to interpret the radiance information improves the understanding and also defines requirements for these sensors. One measure of knowledge of the atmosphere lies in the ability to predict its behavior. Use of numerical and experimental models provides a better understanding of these processes. These efforts are described in the context of satellite data analysis and fundamental studies of atmospheric dynamics which examine selected processes important to the global circulation.

  20. Alterations to global but not local motion processing in long-term ecstasy (MDMA) users.

    Growing evidence indicates that the main psychoactive ingredient in the illegal drug "ecstasy" (methylendioxymethamphetamine) causes reduced activity in the serotonin and gamma-aminobutyric acid (GABA) systems in humans. On the basis of substantial serotonin input to the occipital lobe, recent research investigated visual processing in long-term users and found a larger magnitude of the tilt aftereffect, interpreted to reflect broadened orientation tuning bandwidths. Further research found higher orientation discrimination thresholds and reduced long-range interactions in the primary visual area of ecstasy users. The aim of the present research was to investigate whether serotonin-mediated V1 visual processing deficits in ecstasy users extend to motion processing mechanisms. Forty-five participants (21 controls, 24 drug users) completed two psychophysical studies: A direction discrimination study directly measured local motion processing in V1, while a motion coherence task tested global motion processing in area V5/MT. "Primary" ecstasy users (n = 18), those without substantial polydrug use, had significantly lower global motion thresholds than controls [p = 0.027, Cohen's d = 0.78 (large)], indicating increased sensitivity to global motion stimuli, but no difference in local motion processing (p = 0.365). These results extend on previous research investigating the long-term effects of illicit drugs on visual processing. Two possible explanations are explored: defuse attentional processes may be facilitating spatial pooling of motion signals in users. Alternatively, it may be that a GABA-mediated disruption to V5/MT processing is reducing spatial suppression and therefore improving global motion perception in ecstasy users.

  1. Environmental consequences of electricity sector reforms

    International Nuclear Information System (INIS)

    Wohlgemuth, N.

    1999-01-01

    Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

    Forty years ago David Navon tried to tackle a central problem in psychology concerning the time course of perceptual processing: Do we first see the details (local level) followed by the overall outlay (global level) or is it rather the other way around? He did this by developing a now classical paradigm involving the presentation of compound stimuli; large letters composed of smaller letters. Despite the usefulness of this paradigm it remains uncertain whether effects found with compound stimuli relate directly to visual object recognition. It does so because compound stimuli are not actual objects but rather formations of elements and because the elements that form the global shape of compound stimuli are not features of the global shape but rather objects in their own right. To examine the relationship between performance on Navon's paradigm and visual object processing we derived two indexes from Navon's paradigm that reflect different aspects of the relationship between global and local processing. We find that individual differences on these indexes can explain a considerable amount of variance in two standard object classification paradigms; object decision and superordinate categorization, suggesting that Navon's paradigm does relate to visual object processing.

    The ability to integrate local orientation information into a global form percept was investigated in long-term ecstasy users. Evidence suggests that ecstasy disrupts the serotonin system, with the visual areas of the brain being particularly susceptible. Previous research has found altered orientation processing in the primary visual area (V1) of users, thought to be due to disrupted serotonin-mediated lateral inhibition. The current study aimed to investigate whether orientation deficits extend to higher visual areas involved in global form processing. Forty-five participants completed a psychophysical (Glass pattern) study allowing an investigation into the mechanisms underlying global form processing and sensitivity to changes in the offset of the stimuli (jitter). A subgroup of polydrug-ecstasy users (n=6) with high ecstasy use had significantly higher thresholds for the detection of Glass patterns than controls (n=21, p=0.039) after Bonferroni correction. There was also a significant interaction between jitter level and drug-group, with polydrug-ecstasy users showing reduced sensitivity to alterations in jitter level (p=0.003). These results extend previous research, suggesting disrupted global form processing and reduced sensitivity to orientation jitter with ecstasy use. Further research is needed to investigate this finding in a larger sample of heavy ecstasy users and to differentiate the effects of other drugs. © The Author(s) 2014.

    Turkish electricity reform has progressed slowly due to internal resistance against privatisation, and gained momentum after Electricity Market Law of 2001, prepared in line with EU Energy Acquis and established required institutional and legal framework. Although the eligibility threshold has reached 39% market opening rate, the dominant position of public both as owner and decision-maker is still the major problem in the sector. Currently Turkey is self-sufficient in electricity, but likely to face shortages in 10 years if the growing demand is not met by either speeding the liberalisation process, or joining the South East Europe Electricity Market.

    Teaching global change is one of the great pedagogical challenges of our day because real understanding entails integrating a variety of concepts from different scientific subject areas, including chemistry, physics, and biology, with a variety of causes and impacts in the past, present, and future. With the adoption of the Next Generation Science Standards, which emphasize climate change and other human impacts on natural systems, there has never been a better time to provide instructional support to educators on these topics. In response to this clear need, the University of California Museum of Paleontology, in collaboration with the National Center for Science Education, developed a new web resource for teachers and students titled "Understanding Global Change" (UGC) that introduces the drivers and impacts of global change. This website clarifies the connections among deep time, modern Earth system processes, and anthropogenic influences, and provides K-16 instructors with a wide range of easy-to-use tools, strategies, and lesson plans for communicating these important concepts regarding global change and the basic Earth systems processes. In summer 2014, the UGC website was field-tested during a workshop with 25 K-12 teachers and science educators. Feedback from participants helped the UGC team develop and identify pedagogically sound lesson plans and instructional tools on global change. These resources are accessible through UGC's searchable database, are aligned with NGSS and Common Core, and are categorized by grade level, subject, and level of inquiry-based instruction (confirmation, structured, guided, open). Providing a range of content and tools at levels appropriate for teachers is essential because our initial needs assessment found that educators often feel that they lack the content knowledge and expertise to address complex, but relevant global change issues, such as ocean acidification and deforestation. Ongoing needs assessments and surveys of

  17. Caffeine promotes global spatial processing in habitual and non-habitual caffeine consumers

    2013-10-01

    Full Text Available Information processing is generally biased toward global cues, often at the expense of local information. Equivocal extant data suggests that arousal states may accentuate either a local or global processing bias, at least partially dependent on the nature of the manipulation, task and stimuli. To further differentiate the conditions responsible for such equivocal results we varied caffeine doses to alter physiological arousal states and measured their effect on tasks requiring the retrieval of local versus global spatial knowledge. In a double-blind, repeated-measures design, non-habitual (Exp. 1; N=36, M=42.5±29 mg/day caffeine and habitual (Exp. 2; N=34, M=579.5±311.5 mg/day caffeine caffeine consumers completed four test sessions corresponding to each of four caffeine doses (0 mg, 100 mg, 200 mg, 400 mg. During each test session, participants consumed a capsule containing one of the three doses of caffeine or placebo, waited sixty minutes, and then completed two spatial tasks, one involving memorizing maps and one spatial descriptions. A spatial statement verification task tested local versus global spatial knowledge by differentially probing memory for proximal versus distal landmark relationships. On the map learning task, results indicated that caffeine enhanced memory for distal (i.e. global compared to proximal (i.e. local comparisons at 100 (marginal, 200, and 400 mg caffeine in non-habitual consumers, and marginally beginning at 200 mg caffeine in habitual consumers. On the spatial descriptions task, caffeine enhanced memory for distal compared to proximal comparisons beginning at 100 mg in non-habitual but not habitual consumers. We thus provide evidence that caffeine-induced physiological arousal amplifies global spatial processing biases, and these effects are at least partially driven by habitual caffeine consumption.

    The paper presents a process of cellulose thermal degradation with bio-hydrogen generation and zinc nanostructures synthesis. Production of zinc nanowires and zinc nanoflowers was performed by a novel processes based on cellulose pyrolysis, volatiles reforming and direct reduction of ZnO. The bio-hydrogen generated in situ promoted the ZnO reduction with Zn nanostructures formation by vapor-solid (VS) route. The cellulose and cellulose/ZnO samples were characterized by thermal analyses (TG/DTG/DTA) and the gases evolved were analyzed by FTIR spectroscopy (TG/FTIR). The hydrogen was detected by TPR (Temperature Programmed Reaction) tests. The results showed that in the presence of ZnO the cellulose thermal degradation produced larger amounts of H 2 when compared to pure cellulose. The process was also carried out in a tubular furnace with N 2 atmosphere, at temperatures up to 900 o C, and different heating rates. The nanostructures growth was catalyst-free, without pressure reduction, at temperatures lower than those required in the carbothermal reduction of ZnO with fossil carbon. The nanostructures were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The optical properties were investigated by photoluminescence (PL). One mechanism was presented in an attempt to explain the synthesis of zinc nanostructures that are crystalline, were obtained without significant re-oxidation and whose morphologies are dependent on the heating rates of the process. This route presents a potential use as an industrial process taking into account the simple operational conditions, the low costs of cellulose and the importance of bio-hydrogen and nanostructured zinc.

    Global butter, concentrated milk, and milk powder products use approximately 15% of annual raw milk production. Similar to cheese and fluid milk, dairy processing of these products can be energy intensive. In this paper, we analyzed production and energy data compiled through extensive literature reviews on butter, concentrated milk, milk and whey powder processing across various countries and plants. Magnitudes of national final and primary specific energy consumption (SEC) exhibited large variations across dairy products; in addition, the final SEC of individual plants and products exhibited significant variations within a country and between countries. Furthermore, we quantified national energy intensity indicators (EIIs) accounting for dairy product mixes and technological advancement. The significant variations of SEC and EII values indicate a high degree of likelihood that there is significant potential for energy savings in the global dairy processing industry. Based upon the study samples, we estimate potential energy savings for dairy processing industry in selected countries, and estimates annual reduction of 9-14 million metric-ton carbon-equivalent could be achieved if measures are implemented to lower SEC values by 50-80% in half of global dairy plants. The paper calls for publication of more energy data from the dairy processing industry. - Research highlights: {yields} The specific energy consumption exhibited large variations across dairy products, plants, and countries. {yields} National energy intensity indicators also exhibited significant variations. {yields} There is a large global potential for energy savings and carbon reduction in dairy processing plants. {yields} The paper calls for publication of more energy data from the dairy processing industry.

Furthermore, we quantified national energy intensity indicators (EIIs) accounting for dairy product mixes and technological advancement. The significant variations of SEC and EII values indicate a high degree of likelihood that there is significant potential for energy savings in the global dairy processing industry. Based upon the study samples, we estimate potential energy savings for dairy processing industry in selected countries, and estimates annual reduction of 9-14 million metric-ton carbon-equivalent could be achieved if measures are implemented to lower SEC values by 50-80% in half of global dairy plants. The paper calls for publication of more energy data from the dairy processing industry. (author)

    Full Text Available Alpine regions in Europe, in particular, face demanding local challenges, e.g., the decline in the agriculture and timber industries, and are also prone to global changes, such as in climate, with potentially severe impacts on tourism. We focus on the Visp region in the Upper Valais, Switzerland, and ask how the process of stakeholder involvement in research practice can contribute to a better understanding of the specific challenges and future development of mountainous regions under global change. Based on a coupled human-environment system (HES perspective, we carried out a formative scenario analysis to develop a set of scenarios for the future directions of the Visp region. In addition, we linked these regional scenarios to context scenarios developed at the global and Swiss levels via an external consistency analysis. This method allows the coupling of both the scenario building process and the scenarios as such. We used a functional-dynamic approach to theory-practice cooperation, i.e., the involvement of key stakeholders from, for example, tourism, forestry, and administration, differed in type and intensity during the steps of the research process. In our study, we experienced strong problem awareness among the stakeholders concerning the impacts of global change and local challenges. The guiding research question was commonly defined and problem ownership was more or less balanced. We arrived at six multiscale scenarios that open up future trajectories for the Visp region, and present generic strategies to cope with global and local challenges. The results show that local identity, spatial planning, community budget, and demographic development are important steering elements in the region's future development. We suggest that method-guided transdisciplinary processes result in a richer picture and a more systemic understanding, which enable a discussion of critical and surprising issues.

    Full Text Available The global financial crisis has posed challenges to financial institutions governance. Meeting these challenges requires an understanding of governance dynamics in relation to institutions’ performance within a changing environment. The nature and scope of institutional response to a changing environment depends upon inherited governance structures, including socioeconomic conventions and rules of behavior at the macro level and time, expertise and common commitment of directors at the micro level. Innovation and learning-by-doing in governance can be an effective reform strategy. Innovation in governance may include the establishment of new norms of economic behavior and the transformation of decision-making process and the reallocation of responsibilities to directors and senior management. This may also inform regulatory approaches in strengthening financial institutions governance, based on improved disclosure, independent and competent boards

    1996-01-01

    An environmental tax reform is seen by many as a possible solution to some crucial problems of modern society - pollution, excessive resource consumption and unemployment. Changes in the system of taxation are here seen as a long term process, one that must cheapen the costs of labour and make the costs of resource use more expensive - a process which can also create major changes in our society as to conceptions of quality, work, consumption etc. The conference presented proposals for an ecological tax and duty system that would contribute to: Changing technology so that it becomes more resource and energy effective. Changing the economic mechanisms so that resource consumption and pollution become more expensive while human resources become cheaper. Changing personal life styles and values so that material consumption becomes less decisive for our choices and priorities. An environmental tax reform is neither without problems nor painless. An economy and an industrial sector based on increasing consumption of energy and raw materials will, in the long run, lead to drawbacks that far outweigh those that are connected with an economic re-orientation whose driving force is another conception of nature.

    Differences in self-orientation (or "self-construal") may affect how the visual environment is attended, but the neural and cultural mechanisms that drive this remain unclear. Behavioral studies have demonstrated that people from Western backgrounds with predominant individualistic values are perceptually biased towards local-level information; whereas people from non-Western backgrounds that support collectivist values are preferentially focused on contextual and global-level information. In this study, we compared two groups differing in predominant individualistic (N = 15) vs collectivistic (N = 15) self-orientation. Participants completed a global/local perceptual conflict task whilst undergoing functional Magnetic Resonance Imaging (fMRI) scanning. When participants high in individualistic values attended to the global level (ignoring the local level), greater activity was observed in the frontoparietal and cingulo-opercular networks that underpin attentional control, compared to the match (congruent) baseline. Participants high in collectivistic values activated similar attentional control networks o only when directly compared with global processing. This suggests that global interference was stronger than local interference in the conflict task in the collectivistic group. Both groups showed increased activity in dorsolateral prefrontal regions involved in resolving perceptual conflict during heightened distractor interference. The findings suggest that self-orientation may play an important role in driving attention networks to facilitate interaction with the visual environment.

  11. Matérn-based nonstationary cross-covariance models for global processes

    KAUST Repository

    Jun, Mikyoung

    2014-07-01

    Many spatial processes in environmental applications, such as climate variables and climate model errors on a global scale, exhibit complex nonstationary dependence structure, in not only their marginal covariance but also their cross-covariance. Flexible cross-covariance models for processes on a global scale are critical for an accurate description of each spatial process as well as the cross-dependences between them and also for improved predictions. We propose various ways to produce cross-covariance models, based on the Matérn covariance model class, that are suitable for describing prominent nonstationary characteristics of the global processes. In particular, we seek nonstationary versions of Matérn covariance models whose smoothness parameters vary over space, coupled with a differential operators approach for modeling large-scale nonstationarity. We compare their performance to the performance of some existing models in terms of the aic and spatial predictions in two applications: joint modeling of surface temperature and precipitation, and joint modeling of errors in climate model ensembles. © 2014 Elsevier Inc.

    Visuo-constructive and perceptual abilities have been poorly investigated in children with learning disabilities. The present study focused on local or global visuospatial processing in children with nonverbal learning disability (NLD) and dyslexia compared with typically-developing (TD) controls. Participants were presented with a modified block design task (BDT), in both a typical visuo-constructive version that involves reconstructing figures from blocks, and a perceptual version in which respondents must rapidly match unfragmented figures with a corresponding fragmented target figure. The figures used in the tasks were devised by manipulating two variables: the perceptual cohesiveness and the task uncertainty, stimulating global or local processes. Our results confirmed that children with NLD had more problems with the visuo-constructive version of the task, whereas those with dyslexia showed only a slight difficulty with the visuo-constructive version, but were in greater difficulty with the perceptual version, especially in terms of response times. These findings are interpreted in relation to the slower visual processing speed of children with dyslexia, and to the visuo-constructive problems and difficulty in using flexibly-experienced global vs local processes of children with NLD. The clinical and educational implications of these findings are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The article examines the challenges and trends in integration and disintegration processes of ethnic communities in the world of globalization. Established that ethnic disintegration is inevitable consequence of ethnic integration, and its intensity depends on what method is carried Integration: voluntary or forced. What is important is the fact that in the era of globalization integration and disintegration processes of ethnic communities that are inherent in the very essence of ethnicity, greatly amplified. It was found that entering to the cultural field of ethnic communities of other ethnic entities, penalized sustainable ethnic balance, contributes to the phenomenon of «rejection of other» causes of ethnic conflict and the consequent threat of disintegration of ethnic communities. Disintegration often leads to weakening of the linkages and interactions between components of the integrated system in a multi-ethnic society. However, the author concludes that the process of disintegration cannot be regarded as unambiguously negative because, on the one hand, it contributes to the weakening and decline; and sometimes division of multi-ethnic countries, but on the other hand - it contributes to the birth of the new and revival of the old nation-states, which is particularly important in conditions of transformation of the global community towards the post-industrial and information epoch in the future. In general, the integration and disintegration change each other depending on global processes and their transformations. Therefore, in the era of globalization’s challenges it is important is the effective management of these processes to prevent adverse effects.

    Full Text Available Combined (steam and CO2 reforming is one of the methods to produce syngas for different applications. An energy requirement analysis of steam reforming to dry reforming with intermediate steps of steam reduction and equivalent CO2 addition to the feed fuel for syngas generation has been done to identify condition for optimum process operation. Thermodynamic equilibrium data for combined reforming was generated for temperature range of 400–1000°C at 1 bar pressure and combined oxidant (CO2 + H2O stream to propane (fuel ratio of 3, 6, and 9 by employing the Gibbs free energy minimization algorithm of HSC Chemistry software 5.1. Total energy requirement including preheating and reaction enthalpy calculations were done using the equilibrium product composition. Carbon and methane formation was significantly reduced in combined reforming than pure dry reforming, while the energy requirements were lower than pure steam reforming. Temperatures of minimum energy requirement were found in the data analysis of combined reforming which were optimum for the process.

    The relationship between the global food system and the worldwide rapid increase of obesity and related diseases is not yet well understood. A reason is that the full impact of industrialized food processing on dietary patterns, including the environments of eating and drinking, remains overlooked and underestimated. Many forms of food processing are beneficial. But what is identified and defined here as ultra-processing, a type of process that has become increasingly dominant, at first in high-income countries, and now in middle-income countries, creates attractive, hyper-palatable, cheap, ready-to-consume food products that are characteristically energy-dense, fatty, sugary or salty and generally obesogenic. In this study, the scale of change in purchase and sales of ultra-processed products is examined and the context and implications are discussed. Data come from 79 high- and middle-income countries, with special attention to Canada and Brazil. Results show that ultra-processed products dominate the food supplies of high-income countries, and that their consumption is now rapidly increasing in middle-income countries. It is proposed here that the main driving force now shaping the global food system is transnational food manufacturing, retailing and fast food service corporations whose businesses are based on very profitable, heavily promoted ultra-processed products, many in snack form. © 2013 The Authors.

    Full Text Available The paper provides an overview of the land reform in Russia's recent history. Analysis of land reform, which started in 1990, shows what actions and what logic led the land sector in the state in which it was at the finish line of the quarter-century reform marathon. The reform process was not linear, it highlighted the steps differing objectives and strategies to achieve them. Land reform is presented as a struggle of different political forces, which were reflected in the redistribution of functions between agencies in lobbying for appointment to senior positions promoted various commands. The authors conclude about the gradual displacement of state regulation of land relations, the deliberate destruction of the land management as a basis for the development of land resources.

  3. The global chemical systematics of arc front stratovolcanoes: Evaluating the role of crustal processes

    Science.gov (United States)

    Turner, Stephen J.; Langmuir, Charles H.

    2015-07-01

    Petrogenetic models for convergent margins should be consistent with the global systematics of convergent margin volcanic compositions. A newly developed tool for compiling and screening data from the GEOROC database was used to generate a global dataset of whole rock chemical analyses from arc front stratovolcano samples. Data from 227 volcanoes within 31 volcanic arc segments were first averaged by volcano and then by arc to explore global systematics. Three different methods of data normalization produce consistent results that persist across a wide range of Mg# [Mg# =Mg / (Mg +Fe) ]. Remarkably coherent systematics are present among major and trace element concentrations and ratios, with the exception of three arcs influenced by mantle plumes and Peru/N. Chile, which is built on exceptionally thick crust. Chemical parameters also correlate with the thickness of the overlying arc crust. In addition to previously established correlations of Na6.0 with Ca6.0 and crustal thickness, correlations are observed among major elements, trace elements, and trace element ratios (e.g. La/Yb, Dy/Yb, Zr/Sm, Zr/Ti). Positive correlations include "fluid mobile," "high field strength," and "large ion lithophile" element groups, with concentrations that vary by a factor of five in all groups. Incompatible element enrichments also correlate well with crustal thickness, with the greatest enrichment found at arcs with the thickest crust. Intra-crustal processes, however, do not reproduce the global variations. High pressure fractionation produces intermediate magmas enriched in aluminum, but such magmas are rare. Furthermore, differences among magma compositions at various volcanic arcs persist from primitive to evolved compositions, which is inconsistent with the possibility that global variations are produced by crystal fractionation at any pressure. Linear relationships among elements appear to be consistent with mixing between depleted primary magma and an enriched contaminant

    2012-01-01

    Sex differences in creativity related global-local hemispheric selective processing were examined by hierarchical letter presenting in conditions of their perception and comparison. Fifty-six right-handed males and 68 females (aged 17-22 years) participated in the experiments. Originality-imagery was assessed by a computer-based Torrance 'Incomplete Figures' test software. Verbal creativity was valued by original sentence using of three nouns from remote semantic categories. The results show that irrespectively of the sex factor and the type of creative thinking, its originality is provided by high speed of right-hemispheric processes of information selection on the global level and delay in the interhemispheric communication. Relationships between originality of ideas and hemispheric attentional characteristics are presented mostly in men while verbal creative problem solving, and in women while figurative original thinking. Originality of verbal activity in men is more associated with success of selective processes in the left hemisphere, but in women--with selective functions of both hemispheres. Figurative thinking in men is less related to hemispheric characteristics of attention compared with women. Increase of figurative originality in women is accompanied acceleration of processes of selection of the information in the right hemisphere, and also higher efficiency of local attention as well as speeds ofglobal processing in the left hemisphere.

    Special geochemical studies of oils allowed to allocate a movable migration component of oils in the industrial oil deposits. In the field the migration component of oils varies in different parts of the field. The largest percentage of the light migration component (gas condensate of the oil) was detected in the central part of the Kama-Kinel troughs system. Monitoring of the composition of water, oil and gas (condensate light oil component) in the sedimentary cover and ni crystalline basement led to the conclusion of modern migration of hydrocarbons in sedimentary cover. This proves the existence of the modern processes of formation and reformation of oil and gas fields. This presentation is dedicated to the problem of definition of geochemical criteria of selection of hydrocarbons deposit reformation zone in the sample wells of Minibaevskaya area of Romashkinskoye field. While carrying out this work we examined 11 samples of oil from the Upper Devonian Pashiysky horizon. Four oil samples were collected from wells reckoned among the "anomalous" zones that were marked out according to the results of geophysical, oil field and geological research. Geochemical studies of oils were conducted in the laboratory of geochemistry of the Kazan (Volga-region) Federal University. The wells where the signs of hydrocarbons influx from the deep zones of the crust were recorded are considered to be "anomalous". A number of scientists connect this fact to the hypothesis about periodic influx of deep hydrocarbons to the oil deposits of Romashkinskoye field. Other researchers believe that the source rocks of the adjacent valleys sedimentary cover generate gases when entering the main zone of gas formation, which then migrate up the section and passing through the previously formed deposits of oil, change and "lighten" their composition. Regardless of the point of view on the source of the hydrocarbons, the study of the process of deposits refilling with light hydrocarbons is an

    In 2004, the US government began to utilize the Food and Drug Administration's (USFDA) tentative approval process (tFDA) as a basis to determine which HIV drugs are appropriate to be purchased and used in resource-constrained settings. This process permits products that are not approved for marketing in the US, including medicines with active patents or marketing restrictions in the US, to be purchased and distributed in resource-constrained settings. Although the tFDA was originally intended to support the United States' President's Emergency Plan for AIDS Relief (PEPFAR), the USFDA list has become a cornerstone of international HIV programmes that support procurement of ARVs, such as the World Health Organization and the Global Fund to Fight AIDS, Tuberculosis, and Malaria. Our objective in this article is to help the global HIV policy makers and implementers of HIV programmes better understand the benefits and limitations of the tFDA by providing an in-depth review of the relevant legal and regulatory processes. USFDA's dedicated tFDA process for ARVs used by the PEPFAR programme has a wide impact globally; however, the implementation and the regulatory processes governing the programme have not been thoroughly described in the medical literature. This paper seeks to help stakeholders better understand the legal and regulatory aspects associated with review of ARVs under the tFDA by describing the following: (1) the tFDA and its importance to global ARV procurement; (2) the regulatory pathways for applications under tFDA for the PEPFAR programme, including modifications to applications, review timelines and costs; (3) the role of US patents, US marketing exclusivity rights, and the Medicines Patents Pool in tFDA; and (4) an overview of how applications for PEPFAR programme are processed through the USFDA. We also provide a case study of a new ARV, tenofovir alafenamide fumarate (TAF), not yet reviewed by USFDA for PEPFAR use. In this paper, we describe the

Inside Palestine, legal reform is seen as a prerequisite for democracy and good governance. Outside, legal reform is perceived as integral to the continued peace process with Israel.

  13. Circuit Mechanisms Governing Local vs. Global Motion Processing in Mouse Visual Cortex

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available A withstanding question in neuroscience is how neural circuits encode representations and perceptions of the external world. A particularly well-defined visual computation is the representation of global object motion by pattern direction-selective (PDS cells from convergence of motion of local components represented by component direction-selective (CDS cells. However, how PDS and CDS cells develop their distinct response properties is still unresolved. The visual cortex of the mouse is an attractive model for experimentally solving this issue due to the large molecular and genetic toolbox available. Although mouse visual cortex lacks the highly ordered orientation columns of primates, it is organized in functional sub-networks and contains striate- and extrastriate areas like its primate counterparts. In this Perspective article, we provide an overview of the experimental and theoretical literature on global motion processing based on works in primates and mice. Lastly, we propose what types of experiments could illuminate what circuit mechanisms are governing cortical global visual motion processing. We propose that PDS cells in mouse visual cortex appear as the perfect arena for delineating and solving how individual sensory features extracted by neural circuits in peripheral brain areas are integrated to build our rich cohesive sensory experiences.

  14. Social Movements Facing the Processes of Globalization: Beyond the Paradigms of Class and Identity

    Directory of Open Access Journals (Sweden)

    Verónica Alfaro

    2004-08-01

    Full Text Available This essay focuses on a particular expression of globalization and regionalization that entails social, political, cultural and economic dimensions: social movements. I argue that current social movements are not necessarily articulated only in terms of class struggle-as the major labor movements were for the last two centuries. Neither do they articulate their protests only in terms of identity and recognition-such as women's movements did in the 1960s. Social movements are now most commonly organized around a discourse that combines those two dimensions. Contemporary social movements are expanding from the structural economic and industrial system (and thus abandoning the form of traditional class struggles to cultural and identity grounds. New social movements are now seen more and more as symbolic challengers, because power-that affects everyday life and tries to manipulate and give social meaning to things-is being contested by individuals in both the public and private spheres. Thus movements have a more symbolic function: they are a new kind of media, fighting for symbolic and cultural stakes, and for a different meaning and orientation of social action. However, constructing a collective identity within a social movement is not definitive. A movement's identity is constructed on an everyday basis, and within the process of globalization, the contact and social interaction with others -with the other, which allows the definition of one's own identity-is not only possible but also necessary. This paper considers the Zapatista rebellion in Chiapas as an empirical approach to social movements expanding from regional, local mobilizations and discourse, to more global oriented contentious activities. I argue that the Zapatista movement's identity in 1994 was quite different from the one it has now: the Ejército Zapatista de Liberación Nacional (EZLN, or Zapatista National Liberation Army discourse has been transformed, from having an ethnic

  15. Energy use and implications for efficiency strategies in global fluid-milk processing industry

    Xu Tengfang; Flapper, Joris

    2009-01-01

    The fluid-milk processing industry around the world processes approximately 60% of total raw milk production to create diverse fresh fluid-milk products. This paper reviews energy usage in existing global fluid-milk markets to identify baseline information that allows comparisons of energy performance of individual plants and systems. In this paper, we analyzed energy data compiled through extensive literature reviews on fluid-milk processing across a number of countries and regions. The study has found that the average final energy intensity of individual plants exhibited significant large variations, ranging from 0.2 to 12.6 MJ per kg fluid-milk product across various plants in different countries and regions. In addition, it is observed that while the majority of larger plants tended to exhibit higher energy efficiency, some exceptions existed for smaller plants with higher efficiency. These significant differences have indicated large potential energy-savings opportunities in the sector across many countries. Furthermore, this paper illustrates a positive correlation between implementing energy-monitoring programs and curbing the increasing trend in energy demand per equivalent fluid-milk product over time in the fluid-milk sector, and suggests that developing an energy-benchmarking framework, along with promulgating new policy options should be pursued for improving energy efficiency in global fluid-milk processing industry.

  17. Improved parameterization of managed grassland in a global process-based vegetation model using Bayesian statistics

    Science.gov (United States)

    Rolinski, S.; Müller, C.; Lotze-Campen, H.; Bondeau, A.

    2010-12-01

    More than a quarter of the Earth’s land surface is covered by grassland, which is also the major part (~ 70 %) of the agricultural area. Most of this area is used for livestock production in different degrees of intensity. The dynamic global vegetation model LPJmL (Sitch et al., Global Change Biology, 2003; Bondeau et al., Global Change Biology, 2007) is one of few process-based model that simulates biomass production on managed grasslands at the global scale. The implementation of managed grasslands and its evaluation has received little attention so far, as reference data on grassland productivity are scarce and the definition of grassland extent and usage are highly uncertain. However, grassland productivity is related to large areas, and strongly influences global estimates of carbon and water budgets and should thus be improved. Plants are implemented in LPJmL in an aggregated form as plant functional types assuming that processes concerning carbon and water fluxes are quite similar between species of the same type. Therefore, the parameterization of a functional type is possible with parameters in a physiologically meaningful range of values. The actual choice of the parameter values from the possible and reasonable phase space should satisfy the condition of the best fit of model results and measured data. In order to improve the parameterization of managed grass we follow a combined procedure using model output and measured data of carbon and water fluxes. By comparing carbon and water fluxes simultaneously, we expect well-balanced refinements and avoid over-tuning of the model in only one direction. The comparison of annual biomass from grassland to data from the Food and Agriculture Organization of the United Nations (FAO) per country provide an overview about the order of magnitude and the identification of deviations. The comparison of daily net primary productivity, soil respiration and water fluxes at specific sites (FluxNet Data) provides

    -making process as reform according to this ‘grand reform’ discourse was blocked by a combination of small-scale fishers’ informal networks and the power of the parliamentary majority. After a parliamentary shift in power the new government implemented the ‘grand reform’ gradually whilst new patterns...... of participation and exclusion emerged. In this process, the identities of the participating participants were reinterpreted to fit the new patterns of influence and participation.

Instead, it argues that fishery reform is likely to be the ‘reform of somebody’ and that this ‘somebody’ is itself a changing identity....

  19. Kristeva's Reformation

    Directory of Open Access Journals (Sweden)

    Kelly Oliver

    2014-12-01

    Full Text Available In my brief remarks, I consider what it means to return and rebind—that is to say, the significance of the re for Kristeva’s thought.  Kristeva does not just talk about binding or birth, or unbinding or death, but rather rebinding and rebirth, suggesting that it is a retrospective return rather than an original moment that is crucial.  The most significant moment, then, is not the moment of imaginary plenitude, nor the moment of originary loss, but rather the moment of rebirth that comes through rebinding after the loss of plenitude.  Indeed, Kristeva’s insistence on re-turning suggests that there is no originary moment of plenitude nor of castration or loss, but rather a constant movement of compensation for a recurrent loss.  By emphasizing rebinding and rebirth, she underscores not the loss as cutting wound but rather the healing power of signification, always already inherent within loss.  The flip-side of separation is reattachment.  And rather than just focus on the separation or cut, Kristeva looks to that which allows us to rebind and reattach in order to create relations that sustain us.  Both unbinding and binding are necessary for rebinding.  Thus, by focusing on rebinding, Kristeva insists on the process of unbinding and binding, and the oscillation between them.

  20. FROM GLOBALIZATION TO GLOBALITY- MERGING NON- WESTERN (POST COLONIAL AND WESTERN SOCIETIES INTO A GLOBAL MODERNITY

    Directory of Open Access Journals (Sweden)

    Angela Barakoska

    2014-12-01

    Full Text Available Modernity stands as a widely used term for social change as it involves modification in many forms in the society and the way people develop with different ideologies and movements. Standing on the other side of the traditional and historical, modernity brings new forms of development, communication and connectedness. In this paper it would be discussed whether the globalization processes are leading to merging of the societies and raising a global modernity, hence the influence of the West and the pilgrimages drawn on the other societies would be examined. Change is an unavoidable part of the society seen as a reform, reaction or revolution. However, the historical processes of integration, innovation and development bring different questions and theories. In this paper it would be referred on the integrative inclinations for merging societies, the understanding of modernity and globalization processes that emerge from the historical development and social change.

    2017-06-01

    Full Text Available Background Global health partnerships have grown rapidly in number and scope, yet there has been less emphasis on their evaluation. Gavi, the Vaccine Alliance, is one such public-private partnership; in Gavi-eligible countries partnerships are dynamic networks of immunization actors who work together to support all stages and aspects of Gavi support. This paper describes a conceptual framework – the partnership framework – and analytic approach for evaluating the perceptions of partnerships’ added value as well as the results from an application to one case in Uganda. Methods We used a mixed-methods case study design embedded in the Gavi Full Country Evaluations (FCE to test the partnership framework on Uganda’s human papillomavirus (HPV vaccine application partnership. Data from document review, interviews, and social network surveys enabled the testing of the relationships between partnership framework domains (context, structure, practices, performance, and outcomes. Topic guides were based on the framework domains and network surveys identified working together relationships, professional trust, and perceptions of the effectiveness, efficiency, and legitimacy of the partnership’s role in this process. Results Data from seven in-depth interviews, 11 network surveys and document review were analyzed according to the partnership framework, confirming relationships between the framework domains. Trust was an important contributor to the perceived effectiveness of the process. The network was structured around the EPI program, who was considered the leader of this process. While the structure and composition of the network was largely viewed as supporting an effective and legitimate process, the absence of the Ministry of Education (MoE may have had downstream consequences if this study’s results had not been shared with the Ministry of Health (MoH and acted upon. The partnership was not perceived to have increased the efficiency of

    Full Text Available An unbridled globalization based on a simple premise about earnings and profit may be detrimental to the livelihood of many thousands of individuals. The greed and utter selfishness that result from the adherence to this sort of business practice are the two things that generate more unemployment, misery and degradation than most other characteristics of the human species. These considerations present the challenge for Western societies and call for the implementation of other principles, standards and procedures, such as cooperation, cohesion, development objectives and social responsibility. In the first part of the paper this approach is tested in the case of the EU-US foreign exchange relationships. The second part of the paper raises more general and fundamental issues. While adhering to the Schumpeter-type innovation environment, it aims to introduce the social dimension ahead of the immediate competitiveness and, therefore, argues for the fundamental reform of the catechism of the capitalist manager. The EU, due to its advanced integration, is relatively well-equipped to move towards the new economic system.

  15. The nuclear safeguards system and the process of global governance accountability

    2011-01-01

    Due to rising energy costs and climate concerns, nuclear energy is again being seriously considered as an energy source for several countries. Along with the resurgence of nuclear energy comes the concern of the world if these countries will develop their programs for the peaceful use of nuclear energy. If on one hand the growth potential of nuclear energy should not be stifled, on the other hand it is imperative that a climate of mutual trust is developed, respecting the right of each country to develop its nuclear program without taking a climate of mistrust to a possible 'intention' behind the pursuit of peaceful use of nuclear energy. Therefore, it is essential that appropriate mechanisms of accountability of global governance are institutionalized at the institutional architecture of the international process of nuclear safeguards, more specifically to the nuclear fuel cycle, so that abuses of power in this sphere does not happen, both by countries that aspire to develop projects nuclear, and by the suppliers of technology. In this context, the case study of Brazil and Argentina gained importance, because these two countries have a single binational organization of nuclear safeguards in the world: Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials - ABACC. In the theoretical question, the paper tries to understand what happens with the process of legitimacy and authority of the organizations of global governance by analyzing the degree of publicness and constrictiveness. This work intends to focus on the role of ABACC as an interstate institution of accountability, which has a key role to control the nation States of Brazil and Argentina regarding the appropriate use of nuclear material used in their programs, and analyze how this Agency behaves within of tension legitimacy-authority, taking into account existing studies on accountability in global governance.

    This study quantifies black carbon (BC) processes in three global climate models and one chemistry transport model, with focus on the seasonality of BC transport, emissions, wet and dry deposition in the Arctic. In the models, transport of BC to the Arctic from lower latitudes is the major BC source for this region while Arctic emissions are very small. All models simulated a similar annual cycle of BC transport from lower latitudes to the Arctic, with maximum transport occurring in July. Substantial differences were found in simulated BC burdens and vertical distributions, with CanAM (NorESM) producing the strongest (weakest) seasonal cycle. CanAM also has the shortest annual mean residence time for BC in the Arctic followed by SMHI-MATCH, CESM and NorESM. The relative contribution of wet and dry deposition rates in removing BC varies seasonally and is one of the major factors causing seasonal variations in BC burdens in the Arctic. Overall, considerable differences in wet deposition efficiencies in the models exist and are a leading cause of differences in simulated BC burdens. Results from model sensitivity experiments indicate that scavenging of BC in convective clouds acts to substantially increase the overall efficiency of BC wet deposition in the Arctic, which leads to low BC burdens and a more pronounced seasonal cycle compared to simulations without convective BC scavenging. In contrast, the simulated seasonality of BC concentrations in the upper troposphere is only weakly influenced by wet deposition in stratiform (layer) clouds whereas lower tropospheric concentrations are highly sensitive.

    2004-01-01

    This paper describes the experimental analysis, concomitant with modeling research, to determine improved operating parameters and design of an autothermal reformer. The reformer, utilizing both partial oxidation and steam reforming reactions, along with the water gas shift phenomena is well suited for the mobile application of transportation. This is due to the novel geometry of the autothermal reformer, which seeks to improve the heat transfer characteristics of the process, whereby the exothermic partial oxidation reaction provides the heat energy required to drive the steam reforming reaction, to the point of a thermally neutral system. The paper will present data from the experimental results of reforming iso-octane as a surrogate for gasoline in the form of reformate composition, iso-octane conversion percentages and efficiencies in terms of hydrogen realized per mol of fuel input.

  20. The Effect of Improved Sub-Daily Earth Rotation Models on Global GPS Data Processing

    Science.gov (United States)

    Yoon, S.; Choi, K. K.

    2017-12-01

    Throughout the various International GNSS Service (IGS) products, strong periodic signals have been observed around the 14 day period. This signal is clearly visible in all IGS time-series such as those related to orbit ephemerides, Earth rotation parameters (ERP) and ground station coordinates. Recent studies show that errors in the sub-daily Earth rotation models are the main factors that induce such noise. Current IGS orbit processing standards adopted the IERS 2010 convention and its sub-daily Earth rotation model. Since the IERS convention had published, recent advances in the VLBI analysis have made contributions to update the sub-daily Earth rotation models. We have compared several proposed sub-daily Earth rotation models and show the effect of using those models on orbit ephemeris, Earth rotation parameters and ground station coordinates generated by the NGS global GPS data processing strategy.

    2010-11-01

    The aim of the present study was to investigate the pattern of recollection and familiarity deficits and the modulation of recognition memory performance by the depth of encoding (deep vs. shallow) in transient global amnesia (TGA). Ten patients with TGA and 11 control subjects were assessed during the acute stage and after recovery 7 to 19 days later. Both recollection and familiarity were impaired in the acute stage and showed significant, albeit not complete, recovery by the time of the postacute assessment. The patients did, however, show a significant levels-of-processing effect, which was significantly reduced in acute TGA, but not at follow-up. The significant levels-of-processing effect during acute TGA might be linked to recruitment of the prefrontal cortex. (c) 2010 APA, all rights reserved

  2. Power sector reform in Maharashtra, India

    Totare, Ninad P.; Pandit, Shubha

    2010-01-01

    In early 1990 the power sector in India required an initial set of reforms due to the scarcity of financial resources and its deteriorating technical and commercial efficiency. The Indian power sector is now going through a second stage of reforms in which restructuring of electric supply utilities has taken place. The Maharashtra State Electricity Board (MSEB) initiated reforms in 2005 by dividing the state electricity board into four separate companies. In this paper, the situations that led to the reform of the MSEB and the scope of the work required for an action plan initiated by the state electricity distribution company in the context of the proposed Key Performance Index are discussed. The post-reform status of the distribution company is analyzed with selected key parameters. The study also analyzes the electricity supply model implemented and the effect of a multi-year tariff plan as one of the key milestones of the tariff structure. The various new projects implemented by the distribution company to improve consumer services and the reform experiences of the other states are discussed, along with the future scope of the present reform process.

  3. Stepping back to see the big picture: when obstacles elicit global processing.

    2011-11-01

    Can obstacles prompt people to look at the "big picture" and open up their minds? Do the cognitive effects of obstacles extend beyond the tasks with which they interfere? These questions were addressed in 6 studies involving both physical and nonphysical obstacles and different measures of global versus local processing styles. Perceptual scope increased after participants solved anagrams in the presence, rather than the absence, of an auditory obstacle (random words played in the background; Study 1), particularly among individuals low in volatility (i.e., those who are inclined to stay engaged and finish what they do; Study 4). It also increased immediately after participants encountered a physical obstacle while navigating a maze (Study 3A) and when compared with doing nothing (Study 3B). Conceptual scope increased after participants solved anagrams while hearing random numbers framed as an "obstacle to overcome" rather than a "distraction to ignore" (Study 2) and after participants navigated a maze with a physical obstacle, compared with a maze without a physical obstacle, but only when trait (Study 5) or state (Study 6) volatility was low. Results suggest that obstacles trigger an "if obstacle, then start global processing" response, primarily when people are inclined to stay engaged and finish ongoing activities. Implications for dealing with life's obstacles and related research are discussed.

    Methane forming reactions using either steam or CO 2 have been known to industry for a long time. These endothermic reactions require the investment of a relatively large amount of energy. German researchers, in the 1970's, conceived and developed the idea to use this reaction and the reverse methanation reaction in a closed loop for the transportation and distribution of nuclear heat. The idea was also adopted for use with solar energy as a heat source. Utilizing solar energy as the heat source, the Weismann Institute of Science has fabricated, installed and operated a complete loop capable of the conversion and transportation of over 400 kW of heat. This system can be operated with a wide range of CO 2 /H 2 O/CH 4 feed mixtures. Steam reforming is the common reforming reaction in the ''open loop'' mode for the purpose of synthesis gas production. This is accomplished with a large excess of steam on a nickel catalyst. However, it has only recently been recognized that there is also a substantial market for CO 2 reforming. The CO 2 /CH 4 mixture in various proportions exists in many places and has, so far, not been used efficiently. The sources for this mixture are biogas produced in anaerobic digestion processes and gas resources such as the NATUNA gas field in Indonesia, and many others. Therefore, the system of CO 2 /CH 4 deserves more attention. Commercial catalysts used for steam reforming based on nickel are not suitable for this system. Therefore, other catalysts based on Rhodium and Ruthenium have been developed and some performance data is presented in this paper. Also presented is a conceptual schematic layout of a CO 2 reforming plant and matching methanator. A computer code for a detailed design of the entire loop in a commercial size system has been prepared where optimized operational conditions as well as equipment parameters can be determined.

    Full Text Available Secondary organic aerosols (SOA exert a significant influence on ambient air quality and regional climate. Recent field, laboratorial and modeling studies have confirmed that in-cloud processes contribute to a large fraction of SOA production with large space-time heterogeneity. This study evaluates the key factors that govern the production of cloud-process SOA (SOAcld on a global scale based on the GFDL coupled chemistry-climate model AM3 in which full cloud chemistry is employed. The association between SOAcld production rate and six factors (i.e., liquid water content (LWC, total carbon chemical loss rate (TCloss, temperature, VOC/NOx, OH, and O3 is examined. We find that LWC alone determines the spatial pattern of SOAcld production, particularly over the tropical, subtropical and temperate forest regions, and is strongly correlated with SOAcld production. TCloss ranks the second and mainly represents the seasonal variability of vegetation growth. Other individual factors are essentially uncorrelated spatiotemporally to SOAcld production. We find that the rate of SOAcld production is simultaneously determined by both LWC and TCloss, but responds linearly to LWC and nonlinearly (or concavely to TCloss. A parameterization based on LWC and TCloss can capture well the spatial and temporal variability of the process-based SOAcld formation (R2 = 0.5 and can be easily applied to global three dimensional models to represent the SOA production from cloud processes.

  7. Fast simulation of reconstructed phylogenies under global time-dependent birth-death processes.

    Diversification rates and patterns may be inferred from reconstructed phylogenies. Both the time-dependent and the diversity-dependent birth-death process can produce the same observed patterns of diversity over time. To develop and test new models describing the macro-evolutionary process of diversification, generic and fast algorithms to simulate under these models are necessary. Simulations are not only important for testing and developing models but play an influential role in the assessment of model fit. In the present article, I consider as the model a global time-dependent birth-death process where each species has the same rates but rates may vary over time. For this model, I derive the likelihood of the speciation times from a reconstructed phylogenetic tree and show that each speciation event is independent and identically distributed. This fact can be used to simulate efficiently reconstructed phylogenetic trees when conditioning on the number of species, the time of the process or both. I show the usability of the simulation by approximating the posterior predictive distribution of a birth-death process with decreasing diversification rates applied on a published bird phylogeny (family Cettiidae). The methods described in this manuscript are implemented in the R package TESS, available from the repository CRAN (http://cran.r-project.org/web/packages/TESS/). Supplementary data are available at Bioinformatics online.

    Contemporary science has brought about technological advances and an unprecedented understanding of the natural world. However, there are signs of dysfunction in the scientific community as well as threats from diverse antiscience and political forces. Incentives in the current system place scientists under tremendous stress, discourage cooperation, encourage poor scientific practices, and deter new talent from entering the field. It is time for a discussion of how the scientific enterprise can be reformed to become more effective and robust. Serious reform will require more consistent methodological rigor and a transformation of the current hypercompetitive scientific culture.

  12. Global sensitivity analysis of Alkali-Surfactant-Polymer enhanced oil recovery processes

    After conventional waterflooding processes the residual oil in the reservoir remains as a discontinuous phase in the form of oil drops trapped by capillary forces and is likely to be around 70% of the original oil in place (OOIP). The EOR method so-called Alkaline-Surfactant-Polymer (ASP) flooding has been proved to be effective in reducing the oil residual saturation in laboratory experiments and field projects through reduction of interfacial tension and mobility ratio between oil and water phases. A critical step for the optimal design and control of ASP recovery processes is to find the relative contributions of design variables such as, slug size and chemical concentrations, in the variability of given performance measures (e.g., net present value, cumulative oil recovery), considering a heterogeneous and multiphase petroleum reservoir (sensitivity analysis). Previously reported works using reservoir numerical simulation have been limited to local sensitivity analyses because a global sensitivity analysis may require hundreds or even thousands of computationally expensive evaluations (field scale numerical simulations). To overcome this issue, a surrogate-based approach is suggested. Surrogate-based analysis/optimization makes reference to the idea of constructing an alternative fast model (surrogate) from numerical simulation data and using it for analysis/optimization purposes. This paper presents an efficient global sensitivity approach based on Sobol's method and multiple surrogates (i.e., Polynomial Regression, Kriging, Radial Base Functions and a Weighed Adaptive Model), with the multiple surrogates used to address the uncertainty in the analysis derived from plausible alternative surrogate-modeling schemes. The proposed approach was evaluated in the context of the global sensitivity analysis of a field scale Alkali-Surfactant-Polymer flooding process. The design variables and the performance measure in the ASP process were selected as slug size

  13. The Relevance of Criminal Courts in the Global South

    2017-12-01

    Full Text Available The literature on comparative law has a long and robust tradition, but studies comparing courts and judicial systems are scarce. Comparative studies in the Global South, following Shapiro’s institutional approach, have aimed to measure the involvement of courts in politics by assessing the power of the judiciary in society, the level of judicial independence, and their role in the context of the judicialization of politics. The focus was on the high courts, including either Constitutional or Supreme Courts. Criminal courts have not received similar attention despite the influence of their everyday decisions on people’s lives and their perception of the judicial system. This article argues that developing a comparative approach for criminal courts in the Global South is needed to help understand the role they play in the development of the rule of law and democratic life. This comparative study helps understand the impact of judicial reform programmes in the Global South. These reforms, inspired by a neoliberal paradigm, have focused on improving the efficiency of the courts. The reforms have promoted managerial techniques detrimental to the standards of due process. Any assessment of the impact of the reforms on the courts in the Global South should start by recognising the widely differing settings under which they operate. This context is characterised by serious economic constraints, such as a lack of material and human resources, and a democratic deficit legacy from the past authoritarian regimes, including widespread police abuse and corruption. Given this context, the role of the courts in ensuring due process and the legality of police procedures is crucial. The impact of the judicial reforms promoting managerial rationality in recent decades must be analysed. To examine the role courts are playing in criminal matters, two cases were explored where courts have undergone extensive judicial reforms, Argentina and the Philippines.

    Since about 1990, many developing and transition countries have undertaken market-oriented reforms in their electric power sectors. Despite the widespread adoption of a standard policy model, reform processes and outcomes have often failed to meet expectations. Drawing on an extensive literature review and case studies in Asia, Africa, Latin America, and Eastern Europe, this paper describes common features of non-OECD electricity reform and reappraises reform policies and underlying assumptions. Comparison with the sector-focused policy goals of deregulation in OECD countries highlights the importance of national fiscal crises, macroeconomic reforms, and persuasion by multilateral lenders in shaping non-OECD reforms. It also makes clear reform's dependence on attracting foreign capital, and consequent vulnerability to volatile international financial conditions. Case studies of Bolivia, Ghana, India, Poland, and Thailand illustrate reform's diverse pathways and problems in different settings. A broad range of non-OECD reform experiences indicates that disappointing results have often resulted from a narrow focus on finance and cost recovery, inflexibly applied. The paper concludes that improving reform will require emphasizing a broader set of objectives, including service provision, public benefits, effective regulation, and social/political legitimacy. Above all, reforms must be based on realistic assessments of national needs and capabilities. (author)

    The article argues that Early Childhood Education & Care (ECEC) is being redesigned based on quality reform discourse with references to global knowledge economy across Nordic countries and the EU. This takes place in policy processes that extend from transnational agents like the OECD and EU...... to national governments, local municipalities and ECEC institutions. Drawing on theoretical insights from Foucauldian genealogy, Laclau and others, the article explores how these policy processes reconfigure what counts as quality in ECEC in a Danish context. It is substantiated how the Danish government...... promotes governance structures among municipalities and professionals that pull ECEC into comprehensive educational strategies. This process draws on policy advice from the OECD and EU. Quality reform thus changes in fundamental ways the organisation and content in ECEC. In discourse, learning displaces...

    Thermal plasma technology can be efficiently used in the production of hydrogen and hydrogen-rich gases from methane and a variety of fuels. This paper describes progress in plasma reforming experiments and calculations of high temperature conversion of methane using heterogeneous processes. The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius) and high degree of dissociation and substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (50% H{sub 2}, 17% CO and 33% N{sub 2}, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2--3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H{sub 2} with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content ({approximately} 1.5%) with power densities of {approximately} 30 kW (H{sub 2} HHV)/liter of reactor, or {approximately} 10 m{sup 3}/hr H{sub 2} per liter of reactor. Power density should further increase with increased power and improved design.

    Phosphorus (P) plays a major role in the biogeochemical functioning of aquatic systems. It typically acts as the limiting nutrient for primary productivity in freshwater bodies, and thus the increase in anthropogenic P loads during the XXth century has fuelled the eutrophication of these systems. Total P retention in global rivers has also escalated over this timeframe as demonstrated via a global model that implements the spiralling method at a spatial resolution of 0.5° (IMAGE-GNM, Beusen et al., 2015). Here, we refine this coupled hydrological - nutrient model by including mechanistic biogeochemical interactions that govern the P cycle. Special attention is paid to the representation of particle processes (i.e. particle loading, sedimentation and erosion), which play a major role in P transport and accumulation in aquatic systems. Our preliminary results are compared to measurements of suspended sediments, total P and orthophosphates in selected river basins. Initial model results show that P concentrations are particularly sensitive to particulate load distribution in the river network within a grid cell. This novel modelling approach will eventually allow a better assessment of the amounts of different forms of P (organic P, soluble reactive P, and particulate inorganic P), of P transformation rates and retention in inland waters.

    Carbonaceous deposits on naphtha reforming catalysts play a decisive role in limiting process performance. The deposits negatively after catalyst activity, selectivity and the production cycle of a semi regenerative reformer. The magnitude of negative effect of those deposits is directly proportional to their amounts and complexity. Investigations on used reforming catalysts samples reveal that the amount and type (complexity of the chemical nature) of carbonaceous deposits are directly proportional to the catalysts life on stream and the severity of operating conditions. In addition, the combustibility behavior of carbonaceous deposits on the catalyst samples taken from different reformers are found to be different. Optimal carbon removal, for in situ catalyst regeneration, requires the specific conditions be developed, based on the results of well designed and properly performed investigations of the amount and type of carbonaceous deposits.

    DOE has established the goal, through the Fuel Cells in Transportation Program, of fostering the rapid development and commercialization of fuel cells as economic competitors for the internal combustion engine. Central to this goal is a safe feasible means of supplying hydrogen of the required purity to the vehicular fuel cell system. Two basic strategies are being considered: (1) on-board fuel processing whereby alternative fuels such as methanol, ethanol or natural gas stored on the vehicle undergo reformation and subsequent processing to produce hydrogen, and (2) on-board storage of pure hydrogen provided by stationary fuel processing plants. This report analyzes fuel processor technologies, types of fuel and fuel cell options for on-board reformation. As the Phase 1 of a multi-phased program to develop a prototype multi-fuel reformer system for a fuel cell powered vehicle, the objective of this program was to evaluate the feasibility of a multi-fuel reformer concept and to select a reforming technology for further development in the Phase 2 program, with the ultimate goal of integration with a DOE-designated fuel cell and vehicle configuration. The basic reformer processes examined in this study included catalytic steam reforming (SR), non-catalytic partial oxidation (POX) and catalytic partial oxidation (also known as Autothermal Reforming, or ATR). Fuels under consideration in this study included methanol, ethanol, and natural gas. A systematic evaluation of reforming technologies, fuels, and transportation fuel cell applications was conducted for the purpose of selecting a suitable multi-fuel processor for further development and demonstration in a transportation application.

    Controversy has attended the relationship between risk-adjusted mortality and process-of-care. There would be advantage in the establishment, at the data-base level, of global quantitative indices subsuming the diversity of process-of-care. A retrospective, cohort study of patients identified in the Australian and New Zealand Intensive Care Society Adult Patient Database, 1993-2003, at the level of geographic and ICU-level descriptors (n = 35), for both hospital survivors and non-survivors. Process-of-care indices were established by analysis of: (i) the smoothed time-hazard curve of individual patient discharge and determined by pharmaco-kinetic methods as area under the hazard-curve (AUC), reflecting the integrated experience of the discharge process, and time-to-peak-hazard (TMAX, in days), reflecting the time to maximum rate of hospital discharge; and (ii) individual patient ability to optimize output (as length-of-stay) for recorded data-base physiological inputs; estimated as a technical production-efficiency (TE, scaled [0,(maximum)1]), via the econometric technique of stochastic frontier analysis. For each descriptor, multivariate correlation-relationships between indices and summed mortality probability were determined. The data-set consisted of 223129 patients from 99 ICUs with mean (SD) age and APACHE III score of 59.2(18.9) years and 52.7(30.6) respectively; 41.7% were female and 45.7% were mechanically ventilated within the first 24 hours post-admission.

    Recently, NASA has been looking into utilizing landers that can be propelled by LOX-CH (sub 4), to be used for long duration missions. Using landers that utilize such propellants, also provides the opportunity to use solid oxide fuel cells as a power option, especially since they are able to process methane into a reactant through fuel reformation. One type of reformation, called steam methane reformation, is a process to reform methane into a hydrogen-rich product by reacting methane and steam (fuel cell exhaust) over a catalyst. A steam methane reformation system could potentially use the fuel cell's own exhaust to create a reactant stream that is hydrogen-rich, and requires less internal reforming of the incoming methane. Also, steam reformation may hold some advantages over other types of reforming, such as partial oxidation (PROX) reformation. Steam reformation does not require oxygen, while up to 25 percent can be lost in PROX reformation due to unusable CO (sub 2) reformation. NASA's Johnson Space Center has conducted various phases of steam methane reformation testing, as a viable solution for in-space reformation. This has included using two different types of catalysts, developing a custom reformer, and optimizing the test system to find the optimal performance parameters and operating conditions.

    In 1999 the Victorian primary care and community support system began a process of substantial reform, involving purchasing reforms and a contested selection process between providers in large catchment areas across the State. The Liberal Government's electoral defeat in September 1999 led to a review of these reforms. This paper questions the reforms from a rural perspective. They were based on a generic template that did not consider rural-urban differences in health needs or other differences including socio-economic status, and may have reinforced if not aggravated rural-urban differences in the quality of and access to primary health care in Victoria.

    Seismic inversion of post stack seismic data has until recently been regarded as a reservoir oriented method since the standard inversion techniques rely on extensive well control and a detailed user derived input model. Most seismic inversion techniques further requires a stable wavelet. As a consequence seismic inversion is mainly utilised in mature areas focusing of specific zones only after the seismic data has been interpreted and is well understood. By using an advanced 3-D global technique, seismic inversion is presented as the next standard step in the processing sequence. The technique is robust towards noise within the seismic data, utilizes a time variant wavelet, and derives a low frequency model utilizing the stacking velocities and only limited well control. 4 figs.

    Current understanding and knowledge of the composition and structure of cirrus clouds are reviewed and documented in this paper. In addition, the radiative properties of cirrus clouds as they relate to weather and climate processes are described in detail. To place the relevance and importance of cirrus composition, structure and radiative properties into a global perspective, pertinent results derived from simulation experiments utilizing models with varying degrees of complexity are presented; these have been carried out for the investigation of the influence of cirrus clouds on the thermodynamics and dynamics of the atmosphere. In light of these reviews, suggestions are outlined for cirrus-radiation research activities aimed toward the development and improvement of weather and climate models for a physical understanding of cause and effect relationships and for prediction purposes.

    The capacity of soil to withstand perturbations, whether driven by climate, land use change, or spread of invasive species, depends on its chemical composition and physical state. The dynamic interplay between stable, well buffered soil process domains and thresholds in soil state and function is a strong determinant of soil response to forcing from global change. In terrestrial ecosystems, edaphic responses are often mediated by availability of water and its flux into and through soils. Water influences soil processes in several ways: it supports biological production, hence proton-donor, electron-donor and complexing-ligand production; it determines the advective removal of dissolution products, and it can promote anoxia that leads microorganisms to utilize alternative electron acceptors. As a consequence climate patterns strongly influence global distribution of soil, although within region variability is governed by other factors such as landscape age, parent material and human land use. By contrast, soil properties can vary greatly among climate regions, variation which is guided by the functioning of a suite of chemical processes that tend to maintain chemical status quo. This soil 'buffering' involves acid-base reactions as minerals weather and oxidation-reduction reactions that are driven by microbial respiration. At the planetary scale, soil pH provides a reasonable indicator of process domains and varies from about 3.5 to10, globally, although most soils lie between about 4.5 and 8.5. Those that are above 7.5 are strongly buffered by the carbonate system, those that are characterized by neutral pH (7.5-6) are buffered by release of non-hydrolyzing cations from primary minerals and colloid surfaces, and those that are buffered by hydrolytic aluminum on colloidal surfaces. Alkali and alkaline (with the exception of limestone parent material) soils are usually associated with arid and semiarid conditions, neutral pH soils with young soils in both dry and wet

  12. Reforming Romanian energy policy

    1993-01-01

    Success in reforming energy sector depends on the implementation of the programme of economic reform agreed in February 1993. The difficulty of the negotiations between the International Monetary Fund and the Romanian government reflects the wider difficulties faced by the economy as a whole. They can be blamed in part on the legacy of uneconomic and inflexible industrial development and in part on opposition from interest groups which stand to lose from reform. Nonetheless, in spite of hesitant approach, the government does appear committed to the economic reform necessary to establish a market-oriented economy. But as the danger of a financial crisis engendered by the inadequately supported short-term borrowing of foreign exchange becomes urgent, the question is whether economic reform can be now implemented fast enough to protect economic enterprises and saving from a debt crisis. The scope for further delay in implementing the 1993 economic reform programme is fast disappearing. Procrastination should not be allowed to threaten the success of the reforms achieved in the energy and other sectors of the economy. 8 refs., 2 figs

  13. A multiplex PCR mini-barcode assay to identify processed shark products in the global trade.

    Diego Cardeñosa

    Full Text Available Protecting sharks from overexploitation has become global priority after widespread population declines have occurred. Tracking catches and trade on a species-specific basis has proven challenging, in part due to difficulties in identifying processed shark products such as fins, meat, and liver oil. This has hindered efforts to implement regulations aimed at promoting sustainable use of commercially important species and protection of imperiled species. Genetic approaches to identify shark products exist but are typically based on sequencing or amplifying large DNA regions and may fail to work on heavily processed products in which DNA is degraded. Here, we describe a novel multiplex PCR mini-barcode assay based on two short fragments of the cytochrome oxidase I (COI gene. This assay can identify to species all sharks currently listed on the Convention of International Trade of Endangered Species (CITES and most shark species present in the international trade. It achieves species diagnosis based on a single PCR and one to two downstream DNA sequencing reactions. The assay is capable of identifying highly processed shark products including fins, cooked shark fin soup, and skin-care products containing liver oil. This is a straightforward and reliable identification method for data collection and enforcement of regulations implemented for certain species at all governance levels.

    Between 1995 and 1997, a series of five workshops, henceforth called the Delft process, took place with the aim to explore and enhance use of the IMAGE 2 model to support international climate negotiations. The IMAGE 2 model is a multi-disciplinary, integrated model designed to simulate the dynamics of the global society-biosphere-climate system. The workshops facilitated a dialogue between policy makers and scientists involved in the development and applications of the IMAGE 2 model. In this way, policy makers would benefit from the policy makers on how to improve the policy relevance of the IMAGE 2 model. The evaluation at the end of the workshop series showed that participants have used information from the workshop at international negotiation conferences and in preparation of policy documents. The process shows that creating a forum for direct science-policy interactions can be very useful and productive, and has confirmed the importance of creating an open and constructive atmosphere between policy makers, and between policy makers and analysts, to enhance utilisation of scientific knowledge. The authors' analysis also suggests that many factors have to be 'in the right position at the right time and place' to achieve such a success, and that it is difficult to prevent the occurrence of biases in processes like this. 33 refs

    2006-01-01

    Full Text Available A parameterization for cloud processing is presented that calculates activation of aerosol particles to cloud drops, cloud drop size, and pH-dependent aqueous phase sulfur chemistry. The parameterization is implemented in the global aerosol-climate model ECHAM5-HAM. The cloud processing parameterization uses updraft speed, temperature, and aerosol size and chemical parameters simulated by ECHAM5-HAM to estimate the maximum supersaturation at the cloud base, and subsequently the cloud drop number concentration (CDNC due to activation. In-cloud sulfate production occurs through oxidation of dissolved SO2 by ozone and hydrogen peroxide. The model simulates realistic distributions for annually averaged CDNC although it is underestimated especially in remote marine regions. On average, CDNC is dominated by cloud droplets growing on particles from the accumulation mode, with smaller contributions from the Aitken and coarse modes. The simulations indicate that in-cloud sulfate production is a potentially important source of accumulation mode sized cloud condensation nuclei, due to chemical growth of activated Aitken particles and to enhanced coalescence of processed particles. The strength of this source depends on the distribution of produced sulfate over the activated modes. This distribution is affected by uncertainties in many parameters that play a direct role in particle activation, such as the updraft velocity, the aerosol chemical composition and the organic solubility, and the simulated CDNC is found to be relatively sensitive to these uncertainties.

    Full Text Available Currently, hydrogen is mainly produced through steam reforming of natural gas. However, this conventional process involves environmental and energy security concerns. This has led to the development of alternative technologies for (potentially green hydrogen production. In this work, the environmental and energy performance of biohydrogen produced in Europe via steam reforming of glycerol and bio-oil is evaluated from a life-cycle perspective, and contrasted with that of conventional hydrogen from steam methane reforming. Glycerol as a by-product from the production of rapeseed biodiesel and bio-oil from the fast pyrolysis of poplar biomass are considered. The processing plants are simulated in Aspen Plus® to provide inventory data for the life cycle assessment. The environmental impact potentials evaluated include abiotic depletion, global warming, ozone layer depletion, photochemical oxidant formation, land competition, acidification and eutrophication. Furthermore, the cumulative (total and non-renewable energy demand is calculated, as well as the corresponding renewability scores and life-cycle energy balances and efficiencies of the biohydrogen products. In addition to quantitative evidence of the (expected relevance of the feedstock and impact categories considered, results show that poplar-derived bio-oil could be a suitable feedstock for steam reforming, in contrast to first-generation bioglycerol.

    The project was conducted during the period from 7/1/2012 to 6/30/2017 with three major tasks: (1) data synthesis and development of data assimilation (DA) techniques to constrain modeled ecosystem feedback to climate change; (2) applications of DA techniques to improve process models at different scales from ecosystem to regions and the globe; and 3) improvements of modeling soil carbon (C) dynamics by land surface models. During this period, we have synthesized published data from soil incubation experiments (e.g., Chen et al., 2016; Xu et al., 2016; Feng et al., 2016), global change experiments (e.g., Li et al., 2013; Shi et al., 2015, 2016; Liang et al., 2016) and fluxnet (e.g., Niu et al., 2012., Xia et al., 2015; Li et al., 2016). These data have been organized into multiple data products and have been used to identify general mechanisms and estimate parameters for model improvement. We used the data sets that we collected and the DA techniques to improve model performance of both ecosystem models and global land models. The objectives are: 1) to improve model simulations of litter and soil carbon storage (e.g., Schädel et al., 2013; Hararuk and Luo, 2014; Hararuk et al., 2014; Liang et al., 2015); 2) to explore the effects of CO2, warming and precipitation on ecosystem processes (e.g., van Groenigen et al., 2014; Shi et al., 2015, 2016; Feng et al., 2017); and 3) to estimate parameters variability in different ecosystems (e.g., Li et al., 2016). We developed a traceability framework, which was based on matrix approaches and decomposed the modeled steady-state terrestrial ecosystem carbon storage capacity into four can trace the difference in ecosystem carbon storage capacity among different biomes to four traceable components: net primary productivity (NPP), baseline C residence times, environmental scalars and climate forcing (Xia et al., 2013). With this framework, we can diagnose the differences in modeled carbon storage across ecosystems

  1. Institutions and Cultural Diversity: Effects of Democratic and Propaganda Processes on Local Convergence and Global Diversity.

    2016-01-01

    In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, population size, geography, mass media, and type of social influence play important roles. In the present paper, we investigate for the first time the impact that institutions have on cultural diversity. In our first three studies, we extend existing agent-based models and explore the effects of institutional influence and agent loyalty. We find that higher institutional influence increases cultural diversity, while individuals' loyalty to their institutions has a small, preserving effect. In three further studies, we test how bottom-up and top-down processes of institutional influence impact our model. We find that bottom-up democratic practices, such as referenda, tend to produce convergence towards homogeneity, while top-down information dissemination practices, such as propaganda, further increase diversity. In our last model--an integration of bottom-up and top-down processes into a feedback loop of information--we find that when democratic processes are rare, the effects of propaganda are amplified, i.e., more diversity emerges; however, when democratic processes are common, they are able to neutralize or reverse this propaganda effect. Importantly, our models allow for control over the full spectrum of diversity, so that a manipulation of our parameters can result in preferred levels of diversity, which will be useful for the study of other factors in the future. We discuss possible mechanisms behind our results, applications, and implications for political and social sciences.

Busca-se analisar a cidadania como instrumento e finalidade do processo de trabalho das equipes de seis instituições de atenção extra-hospitalar em saúde mental, da rede pública de Cuiabá (MT, no segundo semestre de 2001. Utiliza-se a dialética marxista como referencial teórico-metodológico. Apesar de se afirmar os direitos de cidadãos para os "pacientes", agora denominados "usuários" dos serviços, o paradoxo entre o conceito de cidadania e "doente mental" não foi problematizado e, portanto, não resulta em atitudes terapêuticas que possibilitem ou assegurem a participação cidadã de profissionais e usuários. A cidadania corresponde a uma abstração, excluída da esfera de trabalho e/ou tratamento. No trabalho alienado não se explicita a situação contraditória na qual os trabalhadores são agentes que operam saberes e práticas tradicionalmente excludentes e, simultaneamente, necessitam superar esse papel e produzir práticas de atenção psicossocial que respeitem o cidadão portador de transtorno mental.Within the Brazilian context, starting at the end of the 20th century, the psychiatric reform presented the necessity to rescue the rights of citizenship for the mentally ill.

    Almeida, Celia

    2017-10-02

    This essay addresses several dimensions that promote and consolidate the growing participation by private stakeholders in the decision-making process in health, emphasizing international and domestic factors that have facilitated and sustained the persistence of the neoliberal political and ideological perspective over the course of nearly thirty years (since the 1990s). The article emphasizes the role of intergovernmental organizations in this process, highlighting public-private interactions at the global and domestic levels, with a specific focus on so-called public-private partnerships (PPPs). The working premise is that such linkages alter the power relations in policy formulation and implementation, with a predominance of private stakeholders. The article presents an overview of the development of PPPs in Europe, Latin America, and Brazil, identifying their specific origins and the simultaneity of triggering events. The text reiterates the importance of not overlooking the power of these actors in dislodging them from this political position, whether in multilateral organizations or national health systems. The aim is to emphasize the importance of more in-depth reflection on the subject, backing debates within the sector. This entire dynamic requires rethinking strategies of resistance to preserve the rights won through centuries of struggle.

    Simulating tropical cyclone (TC) activity with global climate models (GCMs) remains a challenging problem. While some GCMs are able to simulate TC activity that is in good agreement with the observations, many other models exhibit strong biases. Decreasing horizontal grid spacing of the GCM simulations tends to improve the characteristics of simulated TCs, but this enhancement alone does not necessarily lead to greater skill in simulating TC activity. This study uses process-based diagnostics to identify model characteristics that could explain why some GCM simulations are able to produce more realistic TC activity than others. The diagnostics examine how convection, moisture, clouds and related processes are coupled at individual grid points, which yields useful information into how convective parameterizations interact with resolved model dynamics. These diagnostics share similarities with those originally developed to examine the Madden-Julian Oscillations in climate models. This study will examine TCs in eight different GCM simulations performed at NOAA/GFDL, NCAR and NASA that have different horizontal resolutions and ocean coupling. Preliminary results suggest that stronger TCs are closely associated with greater rainfall - thus greater diabatic heating - in the inner-core regions of the storms, which is consistent with previous theoretical studies. Other storm characteristics that can be used to infer why GCM simulations with comparable horizontal grid spacings produce different TC activity will be examined.

  8. Geophysical constraints on geodynamic processes at convergent margins: A global perspective

    2016-04-01

    Convergent margins, being the boundaries between colliding lithospheric plates, form the most disastrous areas in the world due to intensive, strong seismicity and volcanism. We review global geophysical data in order to illustrate the effects of the plate tectonic processes at convergent margins on the crustal and upper mantle structure, seismicity, and geometry of subducting slab. We present global maps of free-air and Bouguer gravity anomalies, heat flow, seismicity, seismic Vs anomalies in the upper mantle, and plate convergence rate, as well as 20 profiles across different convergent margins. A global analysis of these data for three types of convergent margins, formed by ocean-ocean, ocean-continent, and continent-continent collisions, allows us to recognize the following patterns. (1) Plate convergence rate depends on the type of convergent margins and it is significantly larger when, at least, one of the plates is oceanic. However, the oldest oceanic plate in the Pacific ocean has the smallest convergence rate. (2) The presence of an oceanic plate is, in general, required for generation of high-magnitude (M N 8.0) earthquakes and for generating intermediate and deep seismicity along the convergent margins. When oceanic slabs subduct beneath a continent, a gap in the seismogenic zone exists at depths between ca. 250 km and 500 km. Given that the seismogenic zone terminates at ca. 200 km depth in case of continent-continent collision, we propose oceanic origin of subducting slabs beneath the Zagros, the Pamir, and the Vrancea zone. (3) Dip angle of the subducting slab in continent-ocean collision does not correlate neither with the age of subducting oceanic slab, nor with the convergence rate. For ocean-ocean subduction, clear trends are recognized: steeply dipping slabs are characteristic of young subducting plates and of oceanic plates with high convergence rate, with slab rotation towards a near-vertical dip angle at depths below ca. 500 km at very high

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

  12. Effects of Wegener-Bergeron-Findeisen Process on Global Black Carbon Distribution

    Science.gov (United States)

    Qi, L.

    2016-12-01

    In mixed-phase clouds, the Wegener-Bergeron-Findeisen (WBF) process (ice crystals may grow while water drops evaporate, thereby releasing black carbon (BC) particles into the interstitial air) slows down wet scavenging of BC. Rimming (snowflakes fall and collect cloud water drops and the BC in them along their pathways), in contrast, results in more efficient wet scavenging. We systematically investigate the effects of WBF on BC scavenging efficiency, surface BCair, deposition flux, concentration in snow, and washout ratio using a global 3D chemical transport model. We differentiate riming- vs WBF-dominated in-cloud scavenging based on liquid water content and temperature. Specifically, we relate WBF to either temperature or ice mass fraction in mixed-phase clouds. We find that at Jungfraujoch, Switzerland and Abisko, Sweden, where WBF dominates, the discrepancies of simulated BC scavenging efficiency and washout ratio are significantly reduced (from a factor of 3 to 10% and from a factor of 4-5 to a factor of two). However, at Zeppelin, Norway, where riming dominates, simulation of BC scavenging efficiency, BCair, and washout ratio become worse (relative to observations) when WBF is included. There is thus an urgent need for extensive observations to distinguish and characterize riming- versus WBF-dominated aerosol scavenging in mixed-phase clouds and the associated BC scavenging efficiency. We find the reduction resulting from WBF to global BC scavenging efficiency varies substantially, from 8% in the tropics to 76% in the Arctic. The resulting annual mean BCair increases by up to 156% at high altitudes and at northern high latitudes. Overall, WBF halves the model-observation discrepancy (from -65% to -30%) of BCair across North America, Europe, China and the Arctic. Globally WBF increases BC burden from 0.22 to 0.29-0.35 mg m-2 yr-1, which partially explains the gap between observed and previous model simulated BC burdens over land (Bond et al., 2013). In

    1986-12-01

    Following the learned helplessness paradigm, I assessed in this study the effects of global and specific attributions for failure on the generalization of performance deficits in a dissimilar situation. Helplessness training consisted of experience with noncontingent failures on four cognitive discrimination problems attributed to either global or specific causes. Experiment 1 found that performance in a dissimilar situation was impaired following exposure to globally attributed failure. Experiment 2 examined the behavioral effects of the interaction between stable and global attributions of failure. Exposure to unsolvable problems resulted in reduced performance in a dissimilar situation only when failure was attributed to global and stable causes. Finally, Experiment 3 found that learned helplessness deficits were a product of the interaction of global and internal attribution. Performance deficits following unsolvable problems were recorded when failure was attributed to global and internal causes. Results were discussed in terms of the reformulated learned helplessness model.

  15. IRSN global process for leading a comprehensive fire safety analysis for nuclear installations

    2013-01-01

    A fire safety analysis (FSA) is requested to justify the adequacy of fire protection measures set by the operator. A recent document written by IRSN outlines a global process for such a comprehensive fire safety analysis. Thanks to the French nuclear fire safety regulation evolutions, from prescriptive requirements to objective requirements, the proposed fire safety justification process focuses on compliance with performance criteria for fire protection measures. These performance criteria are related to the vulnerability of targets to effects of fire, and not only based upon radiological consequences out side the installation caused by a fire. In his FSA, the operator has to define the safety functions that should continue to ensure its mission even in the case of fire in order to be in compliance with nuclear safety objectives. Then, in order to maintain these safety functions, the operator has to justify the adequacy of fire protection measures, defined according to defence in depth principles. To reach the objective, the analysis process is based on the identification of targets to be protected in order to maintain safety functions, taken into account facility characteristics. These targets include structures, systems, components and personal important to safety. Facility characteristics include, for all operating conditions, potential ignition sources and fire protections systems. One of the key points of the fire analysis is the assessment of possible fire scenarios in the facility. Given the large number of possible fire scenarios, it is then necessary to evaluate 'reference fires' which are the worst case scenarios of all possible fire scenarios and which are used by the operator for the design of fire protection measures.

    Heterogeneity within autism spectrum disorder (ASD) hampers insight in the etiology and stimulates the search for endophenotypes. Endophenotypes should meet several criteria, the most important being the association with ASD and the higher occurrence rate in unaffected ASD relatives than in the general population. We evaluated these criteria for executive functioning (EF) and local-global (L-G) visual processing. By administering an extensive cognitive battery which increases the validity of the measures, we examined which of the cognitive anomalies shown by ASD probands also occur in their unaffected relatives (n = 113) compared to typically developing (TD) controls (n = 100). Microarrays were performed, so we could exclude relatives from probands with a de novo mutation in a known ASD susceptibility copy number variant, thus increasing the probability that genetic risk variants are shared by the ASD relatives. An overview of studies investigating EF and L-G processing in ASD relatives was also provided. For EF, ASD relatives - like ASD probands - showed impairments in response inhibition, cognitive flexibility and generativity (specifically, ideational fluency), and EF impairments in daily life. For L-G visual processing, the ASD relatives showed no anomalies on the tasks, but they reported more attention to detail in daily life. Group differences were similar for siblings and for parents of ASD probands, and yielded larger effect sizes in a multiplex subsample. The group effect sizes for the comparison between ASD probands and TD individuals were generally larger than those of the ASD relatives compared to TD individuals. Impaired cognitive flexibility, ideational fluency and response inhibition are strong candidate endophenotypes for ASD. They could help to delineate etiologically more homogeneous subgroups, which is clinically important to allow assigning ASD probands to different, more targeted, interventions. © 2016 Association for Child and Adolescent

  17. From elements to perception: local and global processing in visual neurons.

    1999-01-01

    Gestalt psychologists in the early part of the century challenged psychophysical notions that perceptual phenomena can be understood from a punctate (atomistic) analysis of the elements present in the stimulus. Their ideas slowed later attempts to explain vision in terms of single-cell recordings from individual neurons. A rapprochement between Gestalt phenomenology and neurophysiology seemed unlikely when the first ECVP was held in Marburg, Germany, in 1978. Since that time, response properties of neurons have been discovered that invite an interpretation of visual phenomena (including illusions) in terms of neuronal processing by long-range interactions, as first proposed by Mach and Hering in the last century. This article traces a personal journey into the early days of neurophysiological vision research to illustrate the progress that has taken place from the first attempts to correlate single-cell responses with visual perceptions. Whereas initially the receptive-field properties of individual classes of cells--e.g., contrast, wavelength, orientation, motion, disparity, and spatial-frequency detectors--were used to account for relatively simple visual phenomena, nowadays complex perceptions are interpreted in terms of long-range interactions, involving many neurons. This change in paradigm from local to global processing was made possible by recent findings, in the cortex, on horizontal interactions and backward propagation (feedback loops) in addition to classical feedforward processing. These mechanisms are exemplified by studies of the tilt effect and tilt aftereffect, direction-specific motion adaptation, illusory contours, filling-in and fading, figure--ground segregation by orientation and motion contrast, and pop-out in dynamic visual-noise patterns. Major questions for future research and a discussion of their epistemological implications conclude the article.

  18. Evaluation of global continental hydrology as simulated by the Land-surface Processes and eXchanges Dynamic Global Vegetation Model

    Full Text Available Global freshwater resources are sensitive to changes in climate, land cover and population density and distribution. The Land-surface Processes and eXchanges Dynamic Global Vegetation Model is a recent development of the Lund-Potsdam-Jena model with improved representation of fire-vegetation interactions. It allows simultaneous consideration of the effects of changes in climate, CO2 concentration, natural vegetation and fire regime shifts on the continental hydrological cycle. Here the model is assessed for its ability to simulate large-scale spatial and temporal runoff patterns, in order to test its suitability for modelling future global water resources. Comparisons are made against observations of streamflow and a composite dataset of modelled and observed runoff (1986–1995 and are also evaluated against soil moisture data and the Palmer Drought Severity Index. The model captures the main features of the geographical distribution of global runoff, but tends to overestimate runoff in much of the Northern Hemisphere (where this can be somewhat accounted for by freshwater consumption and the unrealistic accumulation of the simulated winter snowpack in permafrost regions and the southern tropics. Interannual variability is represented reasonably well at the large catchment scale, as are seasonal flow timings and monthly high and low flow events. Further improvements to the simulation of intra-annual runoff might be achieved via the addition of river flow routing. Overestimates of runoff in some basins could likely be corrected by the inclusion of transmission losses and direct-channel evaporation.

  19. Fossil fuel subsidy reform: lessons from the Indonesian case

    Global assessments of consumption and the Indonesian case show the relevance of non-household consumers of subsidized energy products. As shown in this study, understanding in more nuance how reforms affect them has the potential to improve the reforms that will be developed by policy-makers worldwide. Further study can reinforce the many benefits of successful reform for the countries and societies slowly turning away from these policies of the past. Estimates regarding the amount of public funds utilized to subsidize the production or consumption of fossil fuels are staggering. For 2011, they range from $83 billion in OECD member states, to nearly $4.1 trillion worldwide if environmental externalities are considered. Numerous studies have demonstrated that subsidies repress economic growth, undermine energy sector investment, increase public debt, benefit wealthy citizens over the poor, instigate a rise in illicit activities, and engender greater global and local pollution. The negative effects of fossil fuel subsidies have led numerous governments to reform their energy policies. There has also been a growing international consensus in favor of reform. While the components of successful reform programs have been identified through past case studies, the nature of reforms adopted by several governments that target non-households have not been systematically examined. Since the late 1990s, the Indonesian government has implemented numerous reforms of its fossil fuel subsidies, including measures targeting household as well as non-household energy consumption. In doing so, it has incurred significant fiscal savings. However, an innovative budgetary analysis reveals that households receive a minority, and a declining share, of fossil fuel subsidy funds. This is the case despite the fact that subsidies were implemented to ensure poor households have access to cheap energy. These findings demonstrate the need to consider non-household sectors in the design of fossil

    Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

    Facing increasingly urgent stress on global water scarcity, many reforms have been launched in countries around the world. As the biggest group of natural resource managers, farmers' behaviour is drawing increasingly wide attention. Satisfying new demands for water will depend on farmers' support since, generally, water will need to be transferred from farmers who have historically secure rights. Although water pricing reform is widely considered to lead to water conservation, the uncertainty of its potential impacts hinders the process of reform. This farmer-level empirical research explores farmers' possible responses to introduction of reforms in water pricing. A survey was conducted of about 300 farm households that use water for irrigating crops in Southern Alberta, an area that is facing water shortages and has had to stop issuing new water licences. By using structural equation modelling, the strength and direction of direct and indirect relationships between external, internal and behavioural variables as proposed in general attitude theory have been estimated. Farming as a family engagement, family members' and family unit's characteristics doubtlessly affect farming practice and farm decisions. Farmers' behaviour was explored under the family and farm context. In developing and testing conceptual models that integrate socio-demographic, psychological, farming context and social milieu factors, we may develop a deeper understanding of farmers' behaviour. The findings and recommendations will be beneficial for environmental practitioners and policy makers.

    Selective deficits in visuospatial processing are present early in development among children with perinatal focal brain lesions (PL). Children with right hemisphere PL (RPL) are impaired in configural processing, while children with left hemisphere PL (LPL) are impaired in featural processing. Deficits associated with LPL are less pervasive than those observed with RPL, but this difference may reflect the structure of the tasks used for assessment. Many of the tasks used to date may place greater demands on configural processing, thus highlighting this deficit in the RPL group. This study employed a task designed to place comparable demands on configural and featural processing, providing the opportunity to obtain within-task evidence of differential deficit. Sixty-two 5- to 14-year-old children (19 RPL, 19 LPL, and 24 matched controls) reproduced from memory a series of hierarchical forms (large forms composed of small forms). Global- and local-level reproduction accuracy was scored. Controls were equally accurate on global- and local-level reproduction. Children with RPL were selectively impaired on global accuracy, and children with LPL on local accuracy, thus documenting a double dissociation in global-local processing.

  6. Ecosystem services and biogeochemical cycles on a global scale: valuation of water, carbon and nitrogen processes

    2011-01-01

    Ecosystem services (ES) are provided by healthy ecosystems and are fundamental to support human life. However, natural systems have been degraded all over the world and the process of degradation is partially attributed to the lack of knowledge regarding the economic benefits associated with ES, which usually are not captured in the market. To valuate ES without using conventional approaches, such as the human's willingness-to-pay for ecosystem goods and services, this paper uses a different method based on Energy Systems Theory to estimate prices for biogeochemical flows that affect ecosystem services by considering their emergy content converted to equivalent monetary terms. Ecosystem services related to water, carbon and nitrogen biogeochemical flows were assessed since they are connected to a range of final ecosystem services including climate regulation, hydrological regulation, food production, soil formation and others. Results in this paper indicate that aquifer recharge, groundwater flow, carbon dioxide sequestration, methane emission, biological nitrogen fixation, nitrous oxide emission and nitrogen leaching/runoff are the most critical biogeochemical flows in terrestrial systems. Moreover, monetary values related to biogeochemical flows on a global scale could provide important information for policymakers concerned with payment mechanisms for ecosystem services and costs of greenhouse gas emissions.

    Learning Classifier Systems (LCSs), such as the accuracy-based XCS, evolve distributed problem solutions represented by a population of rules. During evolution, features are specialized, propagated, and recombined to provide increasingly accurate subsolutions. Recently, it was shown that, as in conventional genetic algorithms (GAs), some problems require efficient processing of subsets of features to find problem solutions efficiently. In such problems, standard variation operators of genetic and evolutionary algorithms used in LCSs suffer from potential disruption of groups of interacting features, resulting in poor performance. This paper introduces efficient crossover operators to XCS by incorporating techniques derived from competent GAs: the extended compact GA (ECGA) and the Bayesian optimization algorithm (BOA). Instead of simple crossover operators such as uniform crossover or one-point crossover, ECGA or BOA-derived mechanisms are used to build a probabilistic model of the global population and to generate offspring classifiers locally using the model. Several offspring generation variations are introduced and evaluated. The results show that it is possible to achieve performance similar to runs with an informed crossover operator that is specifically designed to yield ideal problem-dependent exploration, exploiting provided problem structure information. Thus, we create the first competent LCSs, XCS/ECGA and XCS/BOA, that detect dependency structures online and propagate corresponding lower-level dependency structures effectively without any information about these structures given in advance.

  8. Interactions between global processes and local health problems. A human ecology approach to health among indigenous groups in the Amazon

    Directory of Open Access Journals (Sweden)

    Maj-Lis Follér

    Full Text Available This article deals with methodological issues and how to link global processes - social and ecological - with environmental changes and human health in local communities. The discussion concerns how interdisciplinary approaches can help us find tools to develop new knowledge. Scientific knowledge and local knowledge are not seen as opposite epistemological forms, but as socially and culturally constructed. Power and social legitimacy have to be included when analyzing how to deal with the interaction between global processes and local environmental change and the health/disease interface.

    The ecology of forest soils is an important field of research due to the role of forests as carbon sinks. Consequently, a significant amount of information has been accumulated concerning their ecology, especially for temperate and boreal forests. Although most studies have focused on fungi, forest soil bacteria also play important roles in this environment. In forest soils, bacteria inhabit multiple habitats with specific properties, including bulk soil, rhizosphere, litter, and deadwood habitats, where their communities are shaped by nutrient availability and biotic interactions. Bacteria contribute to a range of essential soil processes involved in the cycling of carbon, nitrogen, and phosphorus. They take part in the decomposition of dead plant biomass and are highly important for the decomposition of dead fungal mycelia. In rhizospheres of forest trees, bacteria interact with plant roots and mycorrhizal fungi as commensalists or mycorrhiza helpers. Bacteria also mediate multiple critical steps in the nitrogen cycle, including N fixation. Bacterial communities in forest soils respond to the effects of global change, such as climate warming, increased levels of carbon dioxide, or anthropogenic nitrogen deposition. This response, however, often reflects the specificities of each studied forest ecosystem, and it is still impossible to fully incorporate bacteria into predictive models. The understanding of bacterial ecology in forest soils has advanced dramatically in recent years, but it is still incomplete. The exact extent of the contribution of bacteria to forest ecosystem processes will be recognized only in the future, when the activities of all soil community members are studied simultaneously.

    1986-01-01

    French health care faced the dual crises of rising costs and excess physicians. No government, whether left or right, could avoid focusing reform on the extensive public hospital system. Many differences introduced by the Socialists after 1981 were rhetorical and relational--matters of "democratization" of governance and "control" of physicians. Paradoxically, the two major structural reforms, "departmentalization" and "global budgeting," were extensions of actions begun under preceding governments. Neither has come to fruition yet.

    Llewellyn-Jones, David; Good, Simon; Corlett, Gary

    A pc-based analysis package has been developed, for the dual purposes of, firstly, providing ‘quick-look' capability to research workers inspecting long time-series of global satellite datasets of Sea-surface Temperature (SST); and, secondly, providing an introduction for students, either undergraduates, or advanced high-school students to the characteristics of commonly used analysis techniques for large geophysical data-sets from satellites. Students can also gain insight into the behaviour of some basic climate-related large-scale or global processes. The package gives students immediate access to up to 16 years of continuous global SST data, mainly from the Advanced Along-Track Scanning Radiometer, currently flying on ESA's Envisat satellite. The data are available and are presented in the form of monthly averages and spatial averaged to half-degree or one-sixth degree longitude-latitude grids. There are simple button-operated facilities for defining and calculating box-averages; producing time-series of such averages; defining and displaying transects and their evolution over time; and the examination anomalous behaviour by displaying the difference between observed values and values derived from climatological means. By using these facilities a student rapidly gains familiarity with such processes as annual variability, the El Nĩo effect, as well as major current systems n such as the Gulf Stream and other climatically important phenomena. In fact, the student is given immediate insights into the basic methods of examining geophysical data in a research context, without needing to acquire special analysis skills are go trough lengthy data retrieval and preparation procedures which are more generally required, as precursors to serious investigation, in the research laboratory. This software package, called the Leicester AAATSR Global Analyser (LAGA), is written in a well-known and widely used analysis language and the package can be run by using software

    2017-12-01

    Global education is a part of civic education and upbringing that contributes to their scope through the better understanding of various phenomena and global interdependencies that it affords. It thus represents a response to globalisation processes that has as its goal the development of critical thinking skills in schoolchildren from an early age, with a view to stereotypes and prejudices being combated, human life and human dignity being shown values, and emphasis placed on equality, peace, tolerance, solidarity and equity. The paper considers the reasons for including axiological reflection in school education programmes encompassing matters that are global in nature. Also presented are methods by which to achieve postulates of global education at the primary-school teaching level, as well as the results of research into the level of knowledge on key aspects of this education that are present among primary-school teachers.

  14. High temperature nuclear heat for isothermal reformer

    International Nuclear Information System (INIS)

    Epstein, M.

    2000-01-01

    High temperature nuclear heat can be used to operate a reformer with various feedstock materials. The product synthesis gas can be used not only as a source for hydrogen and as a feedstock for many essential chemical industries, such as ammonia and other products, but also for methanol and synthetic fuels. It can also be burnt directly in a combustion chamber of a gas turbine in an efficient combined cycle and generate electricity. In addition, it can be used as fuel for fuel cells. The reforming reaction is endothermic and the contribution of the nuclear energy to the calorific value of the final product (synthesis gas) is about 25%, compared to the calorific value of the feedstock reactants. If the feedstock is from fossil origin, the nuclear energy contributes to a substantial reduction in CO 2 emission to the atmosphere. The catalytic steam reforming of natural gas is the most common process. However, other feedstock materials, such as biogas, landfill gas and CO 2 -contaminated natural gas, can be reformed as well, either directly or with the addition of steam. The industrial steam reformers are generally fixed bed reactors, and their performance is strongly affected by the heat transfer from the furnace to the catalyst tubes. In top-fired as well as side-fired industrial configurations of steam reformers, the radiation is the main mechanism of heat transfer and convection heat transfer is negligible. The flames and the furnace gas constitute the main sources of the heat. In the nuclear reformers developed primarily in Germany, in connection with the EVA-ADAM project (closed cycle), the nuclear heat is transferred from the nuclear reactor coolant gas by convection, using a heating jacket around the reformer tubes. In this presentation it is proposed that the helium in a secondary loop, used to cool the nuclear reactor, will be employed to evaporate intermediate medium, such as sodium, zinc and aluminum chloride. Then, the vapors of the medium material transfer

    1980-01-01

    The design of a plant for the steam reforming of methane using a High Temperature Reactor has been studied by CEA in connection with the G.E.G.N. This group of companies (CEA, GAZ DE FRANCE, CHARBONNAGES DE FRANCE, CREUSOT-LOIRE, NOVATOME) is in charge of studying the feasibility of the coal gasification process by using a nuclear reactor. The process is based on the hydrogenation of the coal in liquid phase with hydrogen produced by a methane steam reformer. The reformer plant is fed by a pipe of natural gas or SNG. The produced hydrogen feeds the gasification plant which could not be located on the same site. An intermediate hydrogen storage between the two plants could make the coupling more flexible. The gasification plant does not need a great deal of heat and this heat can be satisfied mostly by internal heat exchanges

    Highlights: • Thermodynamic analysis and environmental impact assessment of H 2 production system. • Thermodynamic analysis identifies optimal conditions for H 2 production. • LCA is applied to evaluate the environmental impacts of H 2 production system. • Inventories data are derived from process simulation and from literature review. • Thermal energy process is the main contributor to the environmental impact. - Abstract: In this research, various assessment tools are applied to comprehensively investigate hydrogen production from steam reforming of poultry tallow (PT). These tools investigate the chemical reactions, design and simulate the entire hydrogen production process, study the energetic performance and perform an environment impact assessment using life cycle assessment (LCA) methodology. The chemical reaction investigation identifies thermodynamically optimal operating conditions at which PT may be converted to hydrogen via the steam reforming process. The synthesis gas composition was determined by simulations to minimize the Gibbs free energy using the Aspen Plus™ 10.2 software. These optimal conditions are, subsequently, used in the design and simulation of the entire PT-to-hydrogen process. LCA is applied to evaluate the environmental impacts of PT-to-hydrogen system. The system boundaries include rendering and reforming along with the required transportation process. The reforming inventories data are derived from process simulation in Aspen Plus™, whereas the rendering data are adapted from a literature review. The life cycle inventories data of PT-to-hydrogen are computationally implemented into SimaPro 7.3. A set of seven relevant environmental impact categories are evaluated: global warming, abiotic depletion, acidification, eutrophication, ozone layer depletion, photochemical oxidant formation, and cumulative non-renewable fossil and nuclear energy demand. The results are subject to a systematic sensitivity analysis and compared

    Science.gov (United States)

    Lagowski, J. J.

    1995-09-01

    Since 1991, the National Science Foundation has signed cooperative agreements with 26 states to undertake ambitious and comprehensive initiatives to reform science, mathematics, and technology education. Collectively, those agreements are known as the State Systemic Initiatives (SSI's). Two complimentary programs, The Urban and Rural Systemic Initiatives (USI's and RSI's), address similar reforms in the nation's largest cities and poorest rural areas. The SSI Program departs significantly from past NSF practice in several ways. The funding is for a longer term and is larger in amount, and the NSF is taking a more activist role, seeking to leverage state and private funds and promote the coordination of programs within states. The Initiatives also have a stronger policy orientation than previous NSF programs have had. The NSF strategy is a reflection of the growing and widely held view that meaningful reforms in schools are most likely to be achieved through state initiatives that set clear and ambitious learning goals and standards; align all of the available policy levers in support of reform; stimulate school-level initiatives; and mobilize human and financial resources to support these changes. Two premises underlie systemic reform: (1) all children can meet significantly higher standards if they are asked to do so and given adequate opportunities to master the content, and (2) state and local policy changes can create opportunities by giving schools strong and consistent signals about the changes in practice and performance that are expected. Because this is an enormous investment of Federal resources that is intended to bring about deep, systemic improvement in the nation's ability to teach science and mathematics effectively, the NSF has contracted with a consortium of independent evaluators to conduct a review of the program. The first of the SSI's were funded in 1991, sufficiently long ago to begin to formulate some initial impressions of their impact. Take

    Solid oxide fuel cell (SOFC) is a promising technology for decentralized power generation and cogeneration. This technology has several advantages: the high electric efficiency, which can be theoretically improved through integration in power cycles; the low emissions; and the possibility of using...... a large variety of gaseous fuels. The high operating temperature (700-1000°C) of SOFCs has a number of consequences, the most important of which are the possibility to partially reform the raw fuel in the fuel cell anode compartment and the possibility to use high quality heat for cogeneration....... In this work, different configurations of SOFC systems for decentralized electricity production are considered and studied.

    basis the GE methodology has been evaluated. The conclusion of this evaluation is that the GE methodology my lead to non-conservative and/or non-unique results when predictions of global vibration loading in secondary systems supported by the building structure. For the CO-case the assumption is made by GE that a conservative loading is established if an acoustic source is applied in the system model at the locations of all the vent pipe exits which is identical in magnitude and in time dependence in all vents. The source is derived from the one pipe experiments. This evaluation shows that the correlation between the time signals of the different vent pipe sources is a very significant parameter. This parameter is not possible to identify from one pipe experiment. The estimates of this parameter will strongly effect the calculated structural response both concerning the magnitude and the spatial characteristics. The assumption made by GE may lead to non-conservative responses in main parts of the building. The method developed by GE to predict responses for the CH-loading is by itself a random process. The responses computed by this method can be shown to be non-unique. The variance of predicted response spectra are significant. This effect is a direct result of the technique used to simulate the random behaviour of the start times of individual chuggs at the location of the vent pipe exits, the so called desyncronisation technique

    We systematically investigate the effects of Wegener-Bergeron-Findeisen process (hereafter WBF) on black carbon (BC) scavenging efficiency, surface BCair, deposition flux, concentration in snow (BCsnow, ng g-1), and washout ratio using a global 3-D chemical transport model (GEOS-Chem). We differentiate riming- versus WBF-dominated in-cloud scavenging based on liquid water content (LWC) and temperature. Specifically, we implement an implied WBF parameterization using either temperature or ice mass fraction (IMF) in mixed-phase clouds based on field measurements. We find that at Jungfraujoch, Switzerland, and Abisko, Sweden, where WBF dominates in-cloud scavenging, including the WBF effect strongly reduces the discrepancies of simulated BC scavenging efficiency and washout ratio against observations (from a factor of 3 to 10 % and from a factor of 4-5 to a factor of 2). However, at Zeppelin, Norway, where riming dominates, simulation of BC scavenging efficiency, BCair, and washout ratio become worse (relative to observations) when WBF is included. There is thus an urgent need for extensive observations to distinguish and characterize riming- versus WBF-dominated aerosol scavenging in mixed-phase clouds and the associated BC scavenging efficiency. Our model results show that including the WBF effect lowers global BC scavenging efficiency, with a higher reduction at higher latitudes (8 % in the tropics and up to 76 % in the Arctic). The resulting annual mean BCair increases by up to 156 % at high altitudes and at northern high latitudes because of lower temperature and higher IMF. Overall, WBF halves the model-observation discrepancy (from -65 to -30 %) of BCair across North America, Europe, China and the Arctic. Globally WBF increases BC burden from 0.22 to 0.29-0.35 mg m-2 yr-1, which partially explains the gap between observed and previous model-simulated BC burdens over land. In addition, WBF significantly increases BC lifetime from 5.7 to ˜ 8 days. Additionally

    Full Text Available As in many health care systems, some Canadian jurisdictions have begun shifting away from global hospital budgets. Payment for episodes of care has begun to be implemented. Starting in 2012, the Province of Ontario implemented hospital funding reforms comprising three elements: Global Budgets; Health Based Allocation Method (HBAM; and Quality-Based Procedures (QBP. This evaluation focuses on implementation of QBPs, a procedure/diagnosis-specific funding approach involving a pre-set price per episode of care coupled with best practice clinical pathways. We examined whether or not there was consensus in understanding of the program theory underpinning QBPs and how this may have influenced full and effective implementation of this innovative funding model.We undertook a formative evaluation of QBP implementation.

    The dissertation presents the fundamentals of hydrogen gas processing and CO gas purification methods and, on this basis, develops a method for energetic modularisation of the gas treatment process. All process stages are modelled and analyzed on the basis of mass and energy balances. The theoretical discussion of solution methods for the balance equations of the various process stages is limited to the steam reforming and CO gas purification system. Parameters are defined for energetic assessment of the process variants. The method leads to the identification of energetically optimized process variants. Its main goal is the optimum utilisation of process-internal energy and mass flows. The graphic pinch method is a key component of the method presented; it is adapted to the exemplary process. [German] In der Dissertation wird, ausgehend von der Darstellung der Grundlagen der Wasserstoffgasaufbereitungs- und CO-Gasreinigungsverfahren, eine Methodik zur energetischen Modularisierung des Gasaufbereitungsprozesses entwickelt. Die Modellierung und Analyse der einzelnen Prozessstufen erfolgt auf der Basis von Masse- und Energiebilanzen. Die theoretische Darstellung der Loesungsmethoden fuer die Bilanzgleichungen der einzelnen Prozessstufen ist dabei auf das System Dampfreformierung und CO-Gasreinigung eingegrenzt. Parameter zur energetischen Bewertung der Prozessvarianten werden definiert. Die Methodik fuehrt zur Eingrenzung energetisch optimierter Prozessvarianten. Ihr Hauptziel liegt in der optimalen Nutzung prozessinterner Energie- und Stoffstroeme. Ein zentraler Bestandteil der Methodik ist die graphische Pinch-Methode.

    This paper measures trends in global interpersonal inequality during 1975–2010 using data from the most recent version of the World Income Inequality Database (WIID). The picture that emerges using ‘absolute,’ and even ‘centrist’ measures of inequality, is very different from the results obtained...... by centrist measures such as the Krtscha, could return to 1975 levels, at today's domestic and global per capita income levels, but this would require quite dramatic structural reforms to reduce domestic inequality levels in most countries....... using standard ‘relative’ inequality measures such as the Gini coefficient or Coefficient of Variation. Relative global inequality has declined substantially over the decades. In contrast, ‘absolute’ inequality, as captured by the Standard Deviation and Absolute Gini, has increased considerably...

    International audience; Some of the phenomena where the “globalization” concept is applied include the internationalization of markets, globalization of culture, polítical hegemony of world by some states, or groups of states, the increasing power of supranational institutions, and the development of a global division of labour. A starting point to understand the global division of work is the study of how companies are re-structuring, once they are the key-actors in the decision on which wor...

  13. Managing two cultural identities: the malleability of bicultural identity integration as a function of induced global or local processing.

    Increasingly, individuals identify with two or more cultures. Prior research has found the degree to which individuals chronically integrate these identities (bicultural identity integration; BII) moderates responses to cultural cues: High BII individuals assimilate (adopting biases that are congruent with norms of the cued culture), whereas low BII individuals contrast (adopting biases that are incongruent with these norms). The authors propose BII can also be a psychological state and modulated by shifts in processing styles. In four experiments, the authors induced a global or local processing style using physical posture (Experiment 1) and cognitive manipulations (Experiments 2-4) and found that BII is enhanced in contexts facilitating a more global processing style (i.e., smiling, high-level construal, and similarity focus). The authors also found that contrastive responses to cultural cues are diminished when BII is situationally enhanced. Implications for research on processing style, identity integration, and performance in culture-based situations are discussed.

    Full Text Available Modern land reform, that continues in Ukraine since the beginning of the 90-th of ХХ century, is a logical result of the functioning of society and the state.. It’s prerequisites becames, especially full monopolization of state on ownership of land; absence of payment for land as one of the means of ensuring the rational use of lands; absence on workers motivation for intensive work on the land, etc.. These and other preconditions contributed to soil degradation, production of agricultural products with exceeding of maximum allowable concentrations of pollutants, development of diseases, undermine the gene pool of nature and man. Mentioned reasons determined the goal and objectives of modern land reform, which were originally set out in the preamble to the Resolution of the Verkhovna Rada of Ukraine from December 18, 1990 «On Land Reform» with following changes and additions, and in the implementation of the land-reformation measures gained more complete content. Conducted analysis shows that land reform in Ukraine leads to a change of ownership of land, contributes to solving problems of citizens by land plots, enactment of payment for land usecreation of conditions for the development of land market. Thus changing land relations, is formed legal and regulatory framework of land reform and land market. However, positive developments in the implementation of land reform to end of the 90-th years have not led to a radical and effective upgrade of agricultural production, recovery of investment processes in other branches of industry, improving of welfare of the population. Land reform measures didn’t receive adequate financial support. The ultimate goal - an economically-effective and environmentally safe use of land in Ukraine - has not been achieved. Further reforming of land relations contributed to the adoption in October 2001 of the Land Code of Ukraine in the new edition that created the legal principles of land reform. Since it
