    2016-07-01

    Full Text Available The purpose of this paper is to show features of formation of Ukrainian education policy. According to the author, the formation of the national education policy in Ukraine, as the European Union in its time, must find the thin boundary i.e. the balance between unity and dissimilarity of two dif erent education systems such as Soviet education system, which was inherited after the collapse of the Soviet Union, and European education system, which was unified by requirements of the Bologna Declaration. The author examines the features of the formation and development of Soviet and European education systems. Each of them has certain advantages and disadvantages. The author also presents that major educational reforms, which were only started in Ukraine, took place in Central and Eastern Europe in the late twentieth century. This process was caused by the collapse of bipolar world and scores of countries, which were formed in Europe and sought to European values and democratic reforms. Poland, Hungary, Romania, Slovenia and many other new independent states, which paid in full for socialist regimes, began reforms in education, politics, economics and other areas of activity. We can confidently say that the education system in the new founding countries of Europe not only shifted from one model (Soviet model to another (European model, but rather to achieve high performance in their development. The author points out that it is necessary to require continuing professional development of all categories of people, from teachers to car drivers. This growth must be accompanied with the received diplomas at the reputable higher educational institutions not only in Ukraine, but also abroad. Through this paper the author also wants to suggest that the main provisions of national education policy Ukraine is based on Ukrainian national idea. This national idea sounds as «Ukraine is as keeper of harmony between Eastern and Western Europe».

    Full Text Available Deep rethinking and thorough elaboration require a general plan for the development of the state management in the sphere of foreign economic processes - strategy formation and implementation of foreign economic policy of Ukraine. Formed in conditions of political and economic crisis, it is not aimed at providing qualitative change - innovation development, enhance national business investment, measuring asymmetry foreign trade balance, optimize the structure of imports, increasing competitiveness of Ukrainian goods and so on. Significant changes need in government regulation mechanisms of transformation processes, their system updates, meaningful transition to a model of a market transformations, which combined with effective self-governance. The purpose of the article is to explore the strategic principles of foreign economic policy formation, identifying directions Ukraine’s foreign economic strategy formation and ways to improve its effectiveness. Today in Ukraine needs logically consistent application of the basic model of strategy formation and implementation of foreign economic policy: strategy of protectionism, strategy of competitiveness and foreign economic trade integration strategy. The scale and fragmentation tasks are preventing their full implementation. For a targeted and effective state influence on the economy suggest to build a strategy of foreign economic policy on the principles of consistency, integrity, comprehensiveness, subordination, continuity, dynamism, system-creating relations.

    2013-05-01

    Full Text Available This study analyzes the formation of teachers and its relationships with the skills society. According to Sennett the skills society appears in the capitalism mutations and brings within it the notion of portable potential ability, stimulating the workers, so they can cope with acceleration and the short-term of information. The investigation distinguishes two cognition policies in the formation of teachers: (information and (transformation, which co-exist. The first is based on information and connects knowing with the transmission and processing of symbolic representations. The second is grounded in experience and highlights the inseparable relationship between knowledge and invention. The study suggests that the processes which reduce formation to training and information, aiming for the development of abilities and competences, consider formation as the acquisition of knowledge ready to be consumed. In another direction, training is an inventive process, which is based on problematization and the knowledge construction experience.

    Full Text Available In the article the priorities and public policies that can improve the safety level of the budget of Ukraine have been grounded. Attention on the problems of imbalance and deficiency trends accumulation of public debt has been focused. The detailed analysis of the budget deficit of the European community to further research the main problems of fiscal security has been carried out. The formation of the concept of budget policy should include long-term and medium-term priorities of the state priorities areas have been concluded. Budget policy on public debt must deal with interrelated issues of debt bondage and effective use of public credit, promote economic growth with respect safe level and structure of public debt have been emphasized by author. Debt policy as part of fiscal policy under certain conditions can be a powerful tool to intensify investment and innovation processes in society, promote economic and social development. The reorientation of fiscal policy to address current problems through debt and use it as the basis of investment and innovation development provides an effective public debt management is designed to reduce state budget expenditures on its servicing and repayment, optimizing the scope and structure of debt according to economic growth. The role of debt policy in modern terms increases is clearly subordinate to and consistent with long-term goals and priorities of fiscal policy. There is an urgent development and implementation of effective mechanisms for investing borrowed resources, increasing the efficiency of public investment, including the improvement of organizational, financial, legal and controls. Strategically budget security guarantees only competitive economy, which can be constructed only by recovery and accelerated development of promising sectors of the national economy in the presence of a balanced budget policy.

    Full Text Available The purpose of the paper is a generalization of state protectionism measures concerning the depreciation policy formation, which has resulted in economic growth in countries with a stable economy and their adaptation to economic conditions of Ukraine. Methodology. For writing the paper, the grouping and comparison methods were used for the research of business peculiarities of foreign and national enterprises’ operation and their impact on the enterprise depreciation policy formation; abstract-logic one was used during the examination of peculiarities of depreciation policy formation abroad; analysis and synthesis were used for the investigation of impact factors of different state regulation measures on efficiency of assets’ renewal and enterprise depreciation fund use, as well as stimulation of investments in the science and technology progress. Results. State depreciation policy is the basis in investment and innovation process, as well as one of the most important mechanisms for promoting the self-financing policy. In the developed countries, the state policy concerning the accelerated depreciation has become the main tool for economic growth. Depreciation policy reforming has to be conducted within and out of an enterprise simultaneously. Under existing conditions, the enterprise’s depreciation fund formation is impossible at the expense of its own resources. The changes of regulatory support for enterprise activity are necessary for depreciation fund forming. Tax protectionism has to be carried out in two directions: at the expense of profit redistribution before taxation as the special-purpose funding of fixed assets’ renewal as far as enterprise profitability allows and under the condition of the document approved the renewal of manufacturing capacities after the end of operation period. The control over state protectionism implementation regarding the tax heaven and directing funds for innovative renewal of fixed assets has to

  16. Nuclear processing during star formation

    International Nuclear Information System (INIS)

    Newman, M.J.

    1978-01-01

    A preliminary survey was conducted of the thermonuclear energy release expected during star formation. The destruction of primordial deuterium provides substantial amounts of energy at surprisingly low temperatures, and must be considered in any meaningful treatment of star formation carried to stages in which the internal temperature exceeds a few hundred thousand degrees. Significant energy generation from consumption of initial lithium requires higher temperatures, of the order of a few million degrees. Depletion of primordial beryllium and boron may never provide an important energy source. The approach to equilibrium of the carbon--nitrogen cycle is dominant at temperatures approaching those characteristic of the central regions of main sequence stars. The present calculation should serve as a useful guide in choosing those nuclear processes to be included in a more detailed study. 8 figures, 2 tables

    The disclosure provides a method and apparatus for forming gas hydrates from a two-phase mixture of water and a hydrate forming gas. The two-phase mixture is created in a mixing zone which may be wholly included within the body of a spray nozzle. The two-phase mixture is subsequently sprayed into a reaction zone, where the reaction zone is under pressure and temperature conditions suitable for formation of the gas hydrate. The reaction zone pressure is less than the mixing zone pressure so that expansion of the hydrate-forming gas in the mixture provides a degree of cooling by the Joule-Thompson effect and provides more intimate mixing between the water and the hydrate-forming gas. The result of the process is the formation of gas hydrates continuously and with a greatly reduced induction time. An apparatus for conduct of the method is further provided.

    Stars and their corresponding protoplanetary disks form in different environments of Giant Molecular Clouds. By carrying state-of-the art zoom-simulations with the magnetohydrodynamical code ramses, I investigated the accretion process around young stars that are embedded in such different...... environments. Starting from a turbulent (40 pc) 3 Giant Molecular cloud, efficient use of Adaptive Mesh Refinement technique allowed to resolve the processes inside of protoplanetary disks with grid sizes down to 0.06 AU, thus covering a range of spatial scales of more than six orders of magnitude. Accounting...... abundance in different types of the oldest solids of the Solar System (Calcium Aluminum rich inclusions) is not a result of early supernova injections. Instead, our results suggest thermal processing of dust grains as a likely scenario for the measured differences. Furthermore, the simulations show...

  10. Processes and problems in secondary star formation

    International Nuclear Information System (INIS)

    Klein, R.I.; Whitaker, R.W.; Sandford, M.T. II.

    1984-03-01

    Recent developments relating the conditions in molecular clouds to star formation triggered by a prior stellar generation are reviewed. Primary processes are those that lead to the formation of a first stellar generation. The secondary processes that produce stars in response to effects caused by existing stars are compared and evaluated in terms of the observational data presently available. We discuss the role of turbulence to produce clumpy cloud structures and introduce new work on colliding inter-cloud gas flows leading to non-linear inhomogeneous cloud structures in an intially smooth cloud. This clumpy morphology has important consequences for secondary formation. The triggering processes of supernovae, stellar winds, and H II regions are discussed with emphasis on the consequences for radiation driven implosion as a promising secondary star formation mechanism. Detailed two-dimensional, radiation-hydrodynamic calculations of radiation driven implosion are discussed. This mechanism is shown to be highly efficient in synchronizing the formation of new stars in congruent to 1-3 x 10 4 years and could account for the recent evidence for new massive star formation in several UCHII regions. It is concluded that, while no single theory adequately explains the variety of star formation observed, a uniform description of star formation is likely to involve several secondary processes. Advances in the theory of star formation will require multiple dimensional calculations of coupled processes. The important non-linear interactions include hydrodynamics, radiation transport, and magnetic fields

    A group of heterogeneous agents may form partnerships in pairs. All single agents as well as all partnerships generate values. If two agents choose to cooperate, they need to specify how to split their joint value among one another. In equilibrium, which may or may not exist, no agents have incentives to break up or form new partnerships. This paper proposes a dynamic competitive adjustment process that always either finds an equilibrium or exclusively disproves the existence of any equilibri...

  17. Transforming Government's Policy-making Processes

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available We have seen a lot of very welcome progress in terms of making it easier for citizens to input their views into government policy-making processes. However, governments and citizens are now in a similar situation – after a burst of initial enthusiasm, they are not sure what to do next. Governments have struggled to get the mass participation they would like and where significant participation has occurred, have had difficulty integrating it effectively into existing decision-making processes. Citizens have been unsure what to make of this new apparent openness and where they have engaged, have found it hard to know what difference their input made. The solution is to focus on using technology to make existing policy processes more transparent and more participative rather than creating separate e-participation initiatives. The challenge for governments is to open up the whole of the policy process and be prepared to flag up very clearly and explicitly the difference citizen input made. The challenge for e-democracy advocates is to convince policymakers that their ideas can improve the existing policy process rather than simply generating more inputs into it.

  18. PROSPECTS OF THE REGIONAL INTEGRATION POLICY BASED ON CLUSTER FORMATION

    Full Text Available The purpose of this article is to develop the theoretical foundations of regional integration policy and to determine its prospects on the basis of cluster formation. The authors use such research methods as systematization, comparative and complex analysis, synthesis, statistical method. Within the framework of the research, the concept of regional integration policy is specified, and its integration core – cluster – is allocated. The authors work out an algorithm of regional clustering, which will ensure the growth of economy and tax income. Measures have been proposed to optimize the organizational mechanism of interaction between the participants of the territorial cluster and the authorities that allow to ensure the effective functioning of clusters, including taxation clusters. Based on the results of studying the existing methods for assessing the effectiveness of cluster policy, the authors propose their own approach to evaluating the consequences of implementing the regional integration policy, according to which the list of quantitative and qualitative indicators is defined. The present article systematizes the experience and results of the cluster policy of certain European countries, that made it possible to determine the prospects and synergetic effect from the development of clusters as an integration foundation of regional policy in the Russian Federation. The authors carry out the analysis of activity of cluster formations using the example of the Rostov region – a leader in the formation of conditions for the cluster policy development in the Southern Federal District. 11 clusters and cluster initiatives are developing in this region. As a result, the authors propose measures for support of the already existing clusters and creation of the new ones.

  19. Policy interactions, risk and price formation in carbon markets

    Carbon pricing is an important mechanism for providing companies with incentives to invest in carbon abatement. Price formation in carbon markets involves a complex interplay between policy targets, dynamic technology costs, and market rules. Carbon pricing may under-deliver investment due to R and D externalities, requiring additional policies which themselves affect market prices. Also, abatement costs depend on the extent of technology deployment due to learning-by-doing. This paper introduces an analytical framework based on marginal abatement cost (MAC) curves with the aim of providing an intuitive understanding of the key dynamics and risk factors in carbon markets. The framework extends the usual static MAC representation of the market to incorporate policy interactions and some technology cost dynamics. The analysis indicates that supporting large-scale deployment of mature abatement technologies suppresses the marginal cost of abatement, sometimes to zero, whilst increasing total abatement costs. However, support for early stage R and D may reduce both total abatement cost and carbon price risk. An important aspect of the analysis is in elevating risk management considerations into energy policy formation, as the results of the stochastic modelling indicate wide distributions for the emergence of carbon prices and public costs around the policy expectations.

    Full Text Available The present article analyzes the formation perspective found in official documents regarding Basic Education and the pedagogical practices suggested by them. It also points out the relationship between a curriculum-defining public policy and the didactic organization of what is taught in the schools. Results show that the formation proposed by the above-mentioned documents tries to attend our society’s market demands with its valorization of pedagogical practices for the development of attitudes, values, competences and abilities required by the globalized society. When such formation is placed first and foremost and to the detriment of the transmission and appropriation of disciplines, school education decreases its commitment with scientific culture. In fact, it distances itself from its role in offering the symbolic instruments which are necessary for the students’ integral development.

  2. Formation of strategy and policy of banking credit operations management

    2016-03-01

    Full Text Available The article examines the strategic management of credit operations as the activities on credit strategies of banking institutions, the formation of goals, objectives, and the choice of methods to achieve them. The basis of this is the strategic management analysis of the factors affecting the lending operations, strategic planning, communication mechanisms of strategic and tactical decisions, monitoring the implementation of the strategy and timely adjustments. For the purpose of effective implementation of the developed strategy, the article argues that banks in modern conditions should develop their own internal credit policy which should cover the essential elements and principles of credit at these banks. The study determines that the credit policy is based on the factors determined by the amount of capital assets and loan portfolio, the structure of its clientele, specialization, location, presence of branch network, the situation in the money market.

  8. Processes governing pinch formation in diodes

    International Nuclear Information System (INIS)

    Blaugrund, A.E.; Cooperstein, G.; Goldstein, S.A.

    1975-01-01

    The process of pinch formation in large aspect ratio diodes has been studied by means of streak photography and time-resolved x-ray detectors. A tight pinch is formed at the anode center by a collapsing thin hollow electron beam. The collapse velocity depends, among other things, on the type of material in the top 1 μm layer of the anode. In a tentative model it is assumed that an anode plasma is at least partially created from gases released from the surface layer of the anode by the heating action of the beam. These gases are ionized by primary, backscattered, and secondary electrons. Ions emitted from this plasma modify the electron trajectories in the diode leading to a radial collapse of the hollow electron beam. The observed monotonic dependence of the collapse velocity on the atomic number of the anode material can be explained by the smooth dependence on Z of both the specific heat and the electron backscatter coefficient. In the case of high-Z anodes the ion expansion time appears to be the factor limiting the collapse velocity. Detailed experimental data are presented

  11. Fuzzy social choice models explaining the government formation process

    C Casey, Peter; A Goodman, Carly; Pook, Kelly Nelson; N Mordeson, John; J Wierman, Mark; D Clark, Terry

    2014-01-01

    This book explores the extent to which fuzzy set logic can overcome some of the shortcomings of public choice theory, particularly its inability to provide adequate predictive power in empirical studies. Especially in the case of social preferences, public choice theory has failed to produce the set of alternatives from which collective choices are made.  The book presents empirical findings achieved by the authors in their efforts to predict the outcome of government formation processes in European parliamentary and semi-presidential systems.  Using data from the Comparative Manifesto Project (CMP), the authors propose a new approach that reinterprets error in the coding of CMP data as ambiguity in the actual political positions of parties on the policy dimensions being coded. The range of this error establishes parties’ fuzzy preferences. The set of possible outcomes in the process of government formation is then calculated on the basis of both the fuzzy Pareto set and the fuzzy maximal set, and the pre...

    Highlights: ► There are delays either in the government expenditure or in the tax system. ► Both delays affect fiscal policy outcomes. ► The system of differential equations with two delays may be chaotic. ► Fiscal policy outcomes might be inconsistent with their stabilization purposes. - Abstract: The interest in the impact of fiscal policy lags on economic stability increased in the last decade. Several studies have been made on delays either in the government expenditure or in the tax system, where lags exist between the accrual and the payment of taxes. Nevertheless there is in the literature no model where time delays in government expenditures and in tax revenues are considered together as it happens in the real world. In this paper we remedied this defect and proposed a macro-dynamic model where two delays appear: the first pertains to the public expenditure, the second, to the tax revenue. The resulting system of delayed differential equations is studied qualitatively and numerically. The analysis suggests that only particular combinations of the two delays make the system stable. Prevalently the system is unstable and chaotic motions may arise. This implies that the economy may need appropriate structural changes in the public sector to improve fiscal policy outcomes in such a way they may really be consistent with their stabilization purposes.

    2016-07-01

    Framing research seeks to understand the forces that shape human behaviour in the policy process. It assumes that policy is a social construct and can be cast in a variety of ways to imply multiple legitimate value considerations. Frames provide the cognitive means of making sense of the social world, but discordance among them forms the basis of policy contestation. Framing, as both theory and method, has proven to generate considerable insight into the nature of policy debates in a variety of disciplines. Despite its salience for understanding health policy debates; however, little is known about the ways frames influence the health policy process. A scoping review using the Arksey and O'Malley framework was conducted. The literature on framing in the health sector was reviewed using nine health and social science databases. Articles were included that explicitly reported theory and methods used, data source(s), at least one frame, frame sponsor and evidence of a given frame's effect on the health policy process. A total of 52 articles, from 1996 to 2014, and representing 12 countries, were identified. Much of the research came from the policy studies/political science literature (n = 17) and used a constructivist epistemology. The term 'frame' was used as a label to describe a variety of ideas, packaged as values, social problems, metaphors or arguments. Frames were characterized at various levels of abstraction ranging from general ideological orientations to specific policy positions. Most articles presented multiple frames and showed how actors advocated for them in a highly contested political process. Framing is increasingly an important, yet overlooked aspect of the policy process. Further analysis on frames, framing processes and frame conflict can help researchers and policymakers to understand opaque and highly charged policy issues, which may facilitate the resolution of protracted policy controversies. © The Author 2016.

  20. Galaxy formation: internal mechanisms and cosmological processes

    International Nuclear Information System (INIS)

    Martig, Marie

    2010-01-01

    This thesis is devoted to galaxy formation and evolution in a cosmological context. Cosmological simulations have unveiled two main modes of galaxy growth: hierarchical growth by mergers and accretion of cold gas from cosmic filaments. However, these simulations rarely take into account small scale mechanisms, that govern internal evolution and that are a key ingredient to understand galaxy formation and evolution. Thanks to a new simulation technique that I have developed, I first studied the colors of galaxies, and in particular the reddening of elliptical galaxies. I showed that the gas disk in an elliptical galaxy could be stabilized against star formation because of the galaxy's stellar component being within a spheroid instead of a disk. This mechanism can explain the red colors of some elliptical galaxies that contain a gas disk. I also studied the formation of spiral galaxies: most cosmological simulations cannot explain the formation of Milky Way-like galaxies, i.e. with a large disk and a small bulge. I showed that this issue could be partly solved by taking into account in the simulations the mass loss from evolved stars through stellar winds, planetary nebulae and supernovae explosions.

  1. Integration Processes of Migrants: Research Findings and Policy Challenges

    Directory of Open Access Journals (Sweden)

    Rinus Penninx

    2007-06-01

    Full Text Available This contribution discusses the integration processes of immigrants and minorities with a recent immigrant background, and the policies related to the process of settlement of these newcomers in European societies at all relevant levels: from the local level of municipalities and cities, to the national level of states, and the international level of the European Union. Within this general approach, however, a strong emphasis is put on the local level, since that is the level where such policies have to be implemented and are primarily felt, both by the immigrants themselves and by those parts of society that are most affected by immigration. To describe the current state of integration research and policies, this paper will explore in the first section the nature of integration processes, their conceptualisation and lessons from empirical studies. The reason for devoting some space to these topics is the assertion that any integration policy should be based on a thorough, scientifically-based knowledge of the processes of integration and exclusion: if a policy wants to steer such a process, it should have a clear idea of what instruments it can use possibly to intervene, in which part of the process, and at what particular moment. Such knowledge is a solid starting point for policy-making, but it is not enough. Processes of policy-making and implementation follow their own set course, which do not necessarily run parallel to the process of integration. That is why, in the following section, the author attempts to explain some of these processes. At the end of this paper he returns to the core questions of immigration and integration policies on the one hand, and the relationship between local, national and international integration policies on the other.

    2015-09-01

    In this policy perspective, we outline several conditions to support effective science-policy interaction, with a particular emphasis on improving water governance in transboundary basins. Key conditions include (1) recognizing that science is a crucial but bounded input into water resource decision-making processes; (2) establishing conditions for collaboration and shared commitment among actors; (3) understanding that social or group-learning processes linked to science-policy interaction are enhanced through greater collaboration; (4) accepting that the collaborative production of knowledge about hydrological issues and associated socioeconomic change and institutional responses is essential to build legitimate decision-making processes; and (5) engaging boundary organizations and informal networks of scientists, policy makers, and civil society. We elaborate on these conditions with a diverse set of international examples drawn from a synthesis of our collective experiences in assessing the opportunities and constraints (including the role of power relations) related to governance for water in transboundary settings.

    2014-11-01

    To assess the current public participation in-local health policy and its implications through the analysis of policy networks in health center programs. We examined the decision-making process in sub-health center installations and the implementation process in metabolic syndrome management program cases in two districts ('gu's) of Seoul. Participants of the policy network were selected by the snowballing method and completed self-administered questionnaires. Actors, the interactions among actors, and the characteristics of the network were analyzed by Netminer. The results showed that the public is not yet actively participating in the local public health policy processes of decision-making and implementation. In the decision-making process, most of the network actors were in the public sector, while the private sector was a minor actor and participated in only a limited number of issues after the major decisions were made. In the implementation process, the program was led by the health center, while other actors participated passively. Public participation in Korean public health policy is not yet well activated. Preliminary discussions with various stakeholders, including civil society, are needed before making important local public health policy decisions. In addition, efforts to include local institutions and residents in the implementation process with the public officials are necessary to improve the situation.

    2010-08-01

    Implementation of effective policies to reduce harmful alcohol consumption requires both a good understanding of the policy development process and which strategies are likely to work. To contribute to this understanding by reviewing four specific policy development initiatives that have taken place in South Africa between 1994 and 2009: restrictions on alcohol advertising and counter-advertising, regulation of retail sales of alcohol, alcohol taxation and controls on alcohol packaging. Material was drawn from a record of meetings and conferences held between 1994 and 2009 and a database of reports, newspaper clippings and policy documentation. When the policy process resulted in a concrete outcome there was always a clear recognition of the problem and policy alternatives, but success was more likely if there was an alignment of 'political' forces and/or when there was a determined bureaucracy. The impact of the other factors such as the media, community mobilization, non-governmental organizations (NGOs), the liquor industry and research are also discussed. Future avenues for policy research are identified, including the need for more systematic studies that give greater consideration to economic factors. Alcohol policy development in South Africa takes place in a piecemeal fashion and is the product of various competing influences. Having a comprehensive national alcohol strategy cutting across different sectors may be a better way for other developing countries to proceed.

  13. Why UFI nudges will get stuck in the policy process.

    Science.gov (United States)

    Lawson, Joshua; Howard, Brendan

    2012-01-01

    User financial incentives (UFI), in the context of behavioural public policy, have the potential to shape Canadian health policy by replacing or augmenting traditional information-based mechanisms and by imparting a viewpoint that has traditionally been foreign to the public sphere. Whether or not UFI and more traditional "nudges" should be used, they will likely be limited by traditional moral, efficacy and cost/ benefit challenges, as well as the political and bureaucratic impediments that emerge throughout the policy implementation process. These challenges will likely preclude UFI and nudges from having a transformative effect on public policy, but this new school of thought will likely gain prominence through more amorphous means as more individuals learn and adopt its central theory. We should be excited about the potential of UFI and the use of behavioural public policy, but should temper our excitement with realistic expectations about how extensively such an approach should and will be used.

    A new era of health care reform places increasing pressure on public health leaders and agencies to participate in the public policy arena. Public health professionals have long been comfortable in providing the scientific knowledge base required in policy development. What has been more recent in its evolution, however, is recognition that they must also play an active role in leading and shaping the debate over policy. A profile of effective State legislative policy "entrepreneurs" and their strategies has been developed to assist health agencies in developing such a leadership position. Based on the experiences of State legislative liaison officers, specific strategies for dealing with State legislatures have been identified and are organized into five key areas--agency organization, staff skills, communications, negotiation, and active ongoing involvement. A public health agency must be organized effectively to participate in the legislative policy process. Typically, effective agencies centralize responsibility for policy activities and promote broad and coordinated participation throughout the organization. Playing a key role in the agency's political interventions, the legislative liaison office should be staffed with persons possessing excellent interpersonal skills and a high degree of technical competence. Of central importance to effective legislative policy entrepreneurship is the ability to communicate the agency's position clearly. This includes setting forward a focused policy agenda, documenting policy issues in a meaningful manner, and reaching legislators with the proper information. Once a matter is on the legislative agenda, the agency must be prepared to negotiate and build broad support for the measure. Finally, public health agencies must be active policy players. To take advantage of new opportunities for action, the public health (policy) leader must monitor the political environment continually.By working to anticipate and formulate

    Full Text Available The article conducts historical and analytical analysis of views on the role of state administration in the sphere of economic relations by various economic directions in order to allocate traditional and newest essential reference points of the modern theory of state regulation of economy. It identifies specific features of modern models of economic policy that envisage setting goals by the state, selection of relevant efficient tools and mathematic function, which would describe dependencies between them. It considers the concept of the basic theory of economic policy of Jan Tinbergen, its advantages and shortcomings. It studies prerequisites and conducts analysis of the modern concept of the role of state in economy as a subject of the market. It considers the modern concept of economic socio-dynamics, pursuant to which the main task of the state is maximisation of social usefulness and permanent improvement of the Pareto-optimal. It considers the “socio-dynamic multiplicator” notion, which envisages availability of three main components: social effect from activity of the state, yearning of individuals for creation of something new and availability of formal and informal institutions that united first two elements.

  19. Synthetic aperture radar processing with polar formatted subapertures

    Science.gov (United States)

    Doerry, Armin W.

    Synthetic Aperture Radar (SAR) uses the motion of a small real antenna to synthesize a larger aperture, and thereby achieve very fine azimuth resolution. Efficient SAR image formation requires modelling the radar echo and compensating (focusing) the delay and phase for various positions in the target scene. Polar-Format processing is one successful algorithm developed to process large scenes at fine resolutions, but is still limited, especially at resolutions near a wavelength. This paper shows how using tiers of subapertures can overcome the limitations of Polar-Format processing and increase the focused scene size substantially while using only efficient vector multiplies and Fast Fourier Transforms.

    Full Text Available Background: In almost 30 years since economic reforms or ‘renovation’ (Doimoi were launched, Vietnam has achieved remarkably good health results, in many cases matching those in much higher income countries. This study explores the contribution made by Universal Health Insurance (UHI policies, focusing on the past 15 years. We conducted a mixed method study to describe and assess the policy process relating to health insurance, from agenda setting through implementation and evaluation. Design: The qualitative research methods implemented in this study were 30 in-depth interviews, 4 focus group discussions, expert consultancy, and 420 secondary data review. The data were analyzed by NVivo 7.0. Results: Health insurance in Vietnam was introduced in 1992 and has been elaborated over a 20-year time frame. These processes relate to moving from a contingent to a gradually expanded target population, expanding the scope of the benefit package, and reducing the financial contribution from the insured. The target groups expanded to include 66.8% of the population by 2012. We characterized the policy process relating to UHI as incremental with a learning-by-doing approach, with an emphasis on increasing coverage rather than ensuring a basic service package and financial protection. There was limited involvement of civil society organizations and users in all policy processes. Intertwined political economy factors influenced the policy processes. Conclusions: Incremental policy processes, characterized by a learning-by-doing approach, is appropriate for countries attempting to introduce new health institutions, such as health insurance in Vietnam. Vietnam should continue to mobilize resources in sustainable and viable ways to support the target groups. The country should also adopt a multi-pronged approach to achieving universal access to health services, beyond health insurance.

    Full Text Available The objective of the study is to identify and measure the relationships among stakeholders that influence the process of policy-making in defining legality of timber from private forests. The study focuses on the policy-making process of the Ministry of Forestry Regulation P.38/Menhut-II/2009 on Standard and Guidelines for Assessment of Sustainable Forest Management Performance and Timber Legality Verification of Concessionaire or of the Private Forest License Holder as the subject that has been implemented in several private forest management units as follow: Giri Mukti Wana Tirta in Lampung, Koperasi Serba Usaha APIK in Bali, Koperasi Hutan Jaya Lestari in South East Sulawesi, and Koperasi Wana Lestari Menoreh Kulonprogo in Yogyakarta. This research used a qualitative approach and the analysis method used in this research is a modified-stakeholder analysis that developed by ODA (1995, Reitbergen et al. (1998, and Mayer (2005. The stakeholder analysis shows that the interests and influences do not consider private forest farmers as primary stakeholder during  the process of policy formulation.  The strong national and international interests, supported by high authority could not be influnced by the role of the NGOs and academicians. The imbalance of responsibilities, rights, and revenues that was experienced by  farmers as the manager of private forest when started implementing the policy was more as burdens, it means implementation of the policy was more as burdens. Strong relationships between the Ministry of Forestry with the state as a core could not empower the relationship with private forest farmers. As result, policy assumptions cannot be implemented properly.Keywords: policy making process, timber legality, private forest, stakeholder.DOI: 10.7226/jtfm.19.2.156

    2013-01-01

    The mechanism of nanoparticle formation by wire explosion process has been investigated by optical emission spectroscopy in Antony et al. 2010 [2] [J Quant Spectrosc Radiat Transfer 2010; 111:2509]. It was reported that the size of the nanoparticles formed in Ar ambience increases with increasing pressure, while an opposite trend was observed for the nanoparticles produced in N 2 and He ambiences. However, the physics behind this opposite trend seems unclear. In this work, we have investigated the probable mechanism behind the opposite trend in particle size with pressure of different gases and understand the mechanism of nanoparticle formation in wire explosion process. The experiment was carried out to investigate the effect of ambient gas species (Ar and N 2 ) and pressure on arc plasma formation and its corresponding effects on the characteristics of the produced nanoparticles in wire explosion process. Our results show that the arc plasma formation is probably the mechanism that may account for the opposite trend of particle size with pressure of different gases. -- Highlights: ► Cu nanoparticles have been synthesized by wire explosion technique. ► Investigate the effect of the ambient gas species and pressure. ► Arc plasma formation in wire explosion process is investigated. ► Arc plasma formation plays a crucial role in characteristic of the nanoparticles

    In this review article we discuss the common mechanism for cellular process formation. Besides the podocyte, the mechanism of process formation, including cytoskeletal organization and signal transduction, etc., has been studied using neurons and glias as model systems. There has been an accumulation of data showing common cell biological features of the podocyte and the neuron: 1) Both cells possess long and short cell processes equipped with highly organized cytoskeletal systems; 2) Both show cytoskeletal segregation; microtubules (MTs) and intermediate filaments (IFs) in podocyte primary processes and in neurites, while actin filaments (AFs) are abundant in podocyte foot processes in neuronal synaptic regions; 3) In both cells, process formation is mechanically dependent on MTs, whose assembly is regulated by various microtubule- associated proteins (MAPs); 4) In both cells, process formation is positively regulated by PP2A, a Ser/Thr protein phosphatase; 5) In both cells, process formation is accelerated by laminin, an extracellular matrix protein. In addition, recent data from our and other laboratories have shown that podocyte processes share many features with neuronal dendrites: 1) Podocyte processes and neuronal dendrites possess MTs with mixed polarity, namely, plus-end-distal and minus-end-distal MTs coexist in these processes; 2) To establish the mixed polarity of MTs, both express CHO1/MKLP1, a kinesin-related motor protein, and when its expression is inhibited formation of both podocyte processes and neuronal dendrites is abolished; 3) The elongation of both podocyte processes and neuronal dendrites is supported by rab8-regulated basolateral-type membrane transport; 4) Both podocyte processes and neuronal dendrites express synaptopodin, an actin-associated protein, in a development-dependent manner; interestingly, in both cells, synaptopodin is localized not in the main shaft of processes but in thin short projections from the main shaft.

  8. The Hinkley Point decision: An analysis of the policy process

    International Nuclear Information System (INIS)

    2016-01-01

    In 2006, the British government launched a policy to build nuclear power reactors based on a claim that the power produced would be competitive with fossil fuel and would require no public subsidy. A decade later, it is not clear how many, if any, orders will be placed and the claims on costs and subsidies have proved false. Despite this failure to deliver, the policy is still being pursued with undiminished determination. The finance model that is now proposed is seen as a model other European countries can follow so the success or otherwise of the British nuclear programme will have implications outside the UK. This paper contends that the checks and balances that should weed out misguided policies, have failed. It argues that the most serious failure is with the civil service and its inability to provide politicians with high quality advice – truth to power. It concludes that the failure is likely to be due to the unwillingness of politicians to listen to opinions that conflict with their beliefs. Other weaknesses include the lack of energy expertise in the media, the unwillingness of the public to engage in the policy process and the impotence of Parliamentary Committees. - Highlights: •Britain's nuclear power policy is failing due to high costs and problems of finance. •This has implications for European countries who want to use the same financing model. •The continued pursuit of a failing policy is due to poor advice from civil servants. •Lack of expertise in the media and lack of public engagement have contributed. •Parliamentary processes have not provided proper critical scrutiny.

We apply different notions of stability: myopic team-wise stability, which extends to our setup the concept of pair-wise stability, coalitional stability, where agents are perfectly rational and able to coordinate, and stochastic stability, where agents are myopic and errors occur with vanishing probability. We find that, in many cases, coali...

    2016-05-15

    Polycyclic aromatic hydrocarbons (PAHs) emerged as an important contaminant group in a gamut of processed food groups like dairy, nuts, herbs, beverages, meat products etc. Different cooking processes and processing techniques like roasting, barbecuing, grilling, smoking, heating, drying, baking, ohmic-infrared cooking etc. contribute towards its formation. The level of PAHs depends on factors like distance from heat source, fuel used, level of processing, cooking durations and methods, whereas processes like reuse, conching, concentration, crushing and storage enhance the amount of PAHs in some food items. This review paper provides insight into the impact of dietary intake of PAHs, its levels and formation mechanism in processed food items and possible interventions for prevention and reduction of the PAHs contamination. The gaps and future prospects have also been assessed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2012-01-01

    The impact of global climate change due to increased emissions of greenhouse gases emissions which in turn is a consequence of in particular, the use of fossil fuels, has made EU decision makers to act decisively, e.g. the EU 2020 primary energy target of reducing primary energy use with 20% from 2005 to 2020. The aim of this paper is to present major challenges related to the development and formation of energy policies towards the Swedish industrial and building sector in order to fulfill the EU 2020 primary energy target. This paper is approaching the presented challenges by introducing the theory of Asymmetric Energy Policy Shocks (AEPSs), and addresses some key challenges which are of particular relevance for the fulfilment of the EU 2020 primary energy target for Member States like Sweden which from an energy end-use perspective substantially differs from the EU-25's energy end-use structure. In conclusion, overcoming AEPSs, and moving towards a more Long-Term Energy Policy Approach (LTEPA) will be of key importance for individual Member States, if the 2020 primary energy target is to be fulfilled. - Highlights: ► The paper presents major challenges in regard to the formation of Swedish energy policy for the industry and building sectors. ► The theory of Asymmetric Energy Policy Shocks is introduced. ► Regional differences are important to take into account when designing energy policies for the industry and building sectors.

    Government agencies faced with politically controversial decisions often discount or ignore scientific information, whether from agency staff or nongovernmental scientists. Recent developments in scientific integrity (the ability to perform, use, communicate, and publish science free from censorship or political interference) in Canada, Australia, and the United States demonstrate a similar trajectory. A perceived increase in scientific-integrity abuses provokes concerted pressure by the scientific community, leading to efforts to improve scientific-integrity protections under a new administration. However, protections are often inconsistently applied and are at risk of reversal under administrations publicly hostile to evidence-based policy. We compared recent challenges to scientific integrity to determine what aspects of scientific input into conservation policy are most at risk of political distortion and what can be done to strengthen safeguards against such abuses. To ensure the integrity of outbound communications from government scientists to the public, we suggest governments strengthen scientific integrity policies, include scientists' right to speak freely in collective-bargaining agreements, guarantee public access to scientific information, and strengthen agency culture supporting scientific integrity. To ensure the transparency and integrity with which information from nongovernmental scientists (e.g., submitted comments or formal policy reviews) informs the policy process, we suggest governments broaden the scope of independent reviews, ensure greater diversity of expert input and transparency regarding conflicts of interest, require a substantive response to input from agencies, and engage proactively with scientific societies. For their part, scientists and scientific societies have a responsibility to engage with the public to affirm that science is a crucial resource for developing evidence-based policy and regulations in the public interest.

    Characteristics of cultural policy, as a process, i.e. procedural approach, allows us to see the specific aspects of interaction of subjects over the governmental authorities. However, due to the fact, that in its scale cultural process is the same as political environment of the state, some scientists identify it either with politics in general or with the totality of the shares of behavioral government entities, change their status and influence. Supporters of the institutional approach associates the cultural political process with the functioning and the transformation of the government institutionы, based on a set of the political system reactions on the environmental challenges. As we speak in the current economic conditions in Ukraine is actual the development of anti-crisis measures for the rehabilitation and development of the conceptual approach of cultural policies in the region. As such, the obvious is the development of a measures set by all courses of the plan, that will mutualize the key goals, objectives and tools into a uniform system of measures. This plan should provide the combined model in the region and provide a transition to the zonal management principle of the transition period. In the plan it is also should be provided institutional support for the proposed measures, namely the mechanisms of technological and socio-cultural issues implementation in range of the cultural policy of the society [1, p.18].

    Full Text Available Given the up- dated international difficulties in the completion of studies process, theoretical and practical studies developed in this field are surprisingly scarce. Particularly, there has been a limited quantity of students that support their diploma thesis after completing their credits at the School of Languages and Linguistics at the University of Guayaquil. Consequently, this paper faces the problem of the insufficiencies in the culmination of studies process in relation to the management of the academic and scientific formation. Thus, the objective is: to improve the completion of studies or degree- obtaining processes in university education, through the implementation of a praxiological proposal of academic formation and formative research integration. Accordingly, the author´s experiences systematization is the methodology mainly used. The essential logic for the management of the academic formation and formative research integration was revealed as the main proposal, therefore this is the solution to the problem diagnosed. This is based on a curricular structure, in which each of the subjects was interrelated to each of the essential stages of the scientific research. As main results obtained, the students were able to solve real-life problems diagnosed at educative institutions, also they drew up the draft of their theses.

  1. Factors of formation of the dividend policy of joint stock companies

    Rohov Heorhii K.

    2014-01-01

    Full Text Available The article is devoted to justification of factors of formation of the dividend policy of Ukrainian public joint stock companies (PJSC at the modern stage of development of corporate relations. It analyses specific features of the dividend policy of Ukrainian PJSC, which, in particular, shows that their financial results practically do not influence the practice of net profit distribution. It identifies main factors of formation of the corporate dividend policy and provides theoretical justification of the governing practice of net profit distribution by Ukrainian PJSC under the modern state of the stock market. It justifies that the unrepresentative listing of stock exchanges, extremely high concentration of capital and rather limited influence of institutes of joint investment are key factors that cause a very weak reaction of the Ukrainian securities market on payment of dividends, which, in its turn, is the main reason of rejection of expediency of development and realisation of the consistent dividend policy by overwhelming majority of joint stock companies. The article draws a conclusion that the basis of evolution changes in the corporate vision of the dividend policy should be creation of the institutional environment, which would be adequate to the needs of sustainable development. The article offers to fix, at the legislative level and while being at the transitional stage, the right of minor shareholders to get income from owning ordinary shares of companies, which aggregate joint participation of co-owners is more than 75%.

    The ''Model National Environmental Policy Act (NEPA) Process'' includes: References to regulations, guidance documents, and plans; training programs; procedures; and computer databases. Legislative Acts and reference documents from Congress, US Department of Energy, and Lockheed Idaho Technologies Company provide the bases for conducting NEPA at the Idaho National Engineering Laboratory (INEL). Lockheed Idaho Technologies Company (LITCO) NEPA / Permitting Department, the Contractor Environmental Organization (CEO) is responsible for developing and maintaining LITCO NEPA and permitting policies, guidance, and procedures. The CEO develops procedures to conduct environmental evaluations based on NEPA, Council on Environmental Quality (CEQ) regulations, and DOE guidance. This procedure includes preparation or support of environmental checklists, categorical exclusion determinations, environmental assessment determinations, environmental assessments, and environmental impact statements. In addition, the CEO uses this information to train personnel conducting environmental evaluations at the INEL. Streamlining these procedures fosters efficient use of resources, quality documents, and better decisions on proposed actions

  3. The Process Architecture of EU Territorial Cohesion Policy

    Directory of Open Access Journals (Sweden)

    Andreas Faludi

    2010-08-01

    Full Text Available When preparing the European Spatial Development Perspective (ESDP, Member States were supported by the European Commission but denied the EU a competence in the matter. Currently, the Treaty of Lisbon identifies territorial cohesion as a competence shared between the Union and the Member States. This paper is about the process architecture of territorial cohesion policy. In the past, this architecture resembled the Open Method of Coordination (OMC which the White Paper on European Governance praised, but only in areas where there was no EU competence. This reflected zero-sum thinking which may continue even under the Lisbon Treaty. After all, for as long as territorial cohesion was not a competence, voluntary cooperation as practiced in the ESDP process was pursued in this way. However, the practice of EU policies, even in areas where there is an EU competence, often exhibits features of the OMC. Surprisingly effective innovations hold the promise of rendering institutions of decision making comprehensible and democratically accountable. In the EU as a functioning polity decision making is thus at least part deliberative so that actors’ preferences are transformed by the force of the better argument. This brings into focus the socialisation of the deliberators into epistemic communities. Largely an informal process, this is reminiscent of European spatial planning having been characterised as a learning process.

The purpose of this work is to analyze the monetary policies applied by the main central banks, mainly the European Central Bank, the Federal Reserve System of USA and the Bank of Japan, in order to raise thoughts on the guidelines that central banks should follow in the future. In the first section the bases of monetary policy before the crisis are described; in the second we explain the change in the orientation of the role of central banks during the crisis; and finally, we synthesize the bases on which the economic debate is taking place on the orientation of future monetary policies. We conclude that, in so far as the inoperativeness of transmission mechanisms still persists, monetary policies will remain in a process of change.

  5. Modified Polar-Format Software for Processing SAR Data

    2003-01-01

    HMPF is a computer program that implements a modified polar-format algorithm for processing data from spaceborne synthetic-aperture radar (SAR) systems. Unlike prior polar-format processing algorithms, this algorithm is based on the assumption that the radar signal wavefronts are spherical rather than planar. The algorithm provides for resampling of SAR pulse data from slant range to radial distance from the center of a reference sphere that is nominally the local Earth surface. Then, invoking the projection-slice theorem, the resampled pulse data are Fourier-transformed over radial distance, arranged in the wavenumber domain according to the acquisition geometry, resampled to a Cartesian grid, and inverse-Fourier-transformed. The result of this process is the focused SAR image. HMPF, and perhaps other programs that implement variants of the algorithm, may give better accuracy than do prior algorithms for processing strip-map SAR data from high altitudes and may give better phase preservation relative to prior polar-format algorithms for processing spotlight-mode SAR data.

    In Nigeria, there is a high burden of oral health diseases, poor coordination of health services and human resources for delivery of oral health services. Previous attempts to develop an Oral Health Policy (OHP) to decrease the oral disease burden failed. However, a policy was eventually developed in November 2012. This paper explores the role of contextual factors, actors and the policy process in the development of the OHP and possible reasons why the current approved OHP succeeded. The study was undertaken across Nigeria; information gathered through document reviews and in-depth interviews with five groups of purposively selected respondents. Analysis of the policy development process was guided by the policy triangle framework, examining context, policy process and actors involved in the policy development. The foremost enabling factor was the yearning among policy actors for a policy, having had four failed attempts. Other factors were the presence of a democratically elected government, a framework for health sector reform instituted by the Federal Ministry of Health (FMOH). The approved OHP went through all stages required for policy development unlike the previous attempts. Three groups of actors played crucial roles in the process, namely academics/researchers, development partners and policy makers. They either had decision making powers or influenced policy through funding or technical ability to generate credible research evidence, all sharing a common interest in developing the OHP. Although evidence was used to inform the development of the policy, the complex interactions between the context and actors facilitated its approval. The OHP development succeeded through a complex inter-relationship of context, process and actors, clearly illustrating that none of these factors could have, in isolation, catalyzed the policy development. Availability of evidence is necessary but not sufficient for developing policies in this area. Wider socio

    Full Text Available Since the late 1990s there has been a remarkable change in the institutional context of safety and security policies for the Faroes. The end of the Cold War led to a reduction in the strategic importance of, and military presence in, the islands. However, today Faroese sea and air space is increasingly exposed to heavy civilian traffic due to expected oil production as well as new sailing routes from the High North. The Faroese government is in a process, nearly completed, of taking over the full responsibility for societal security policy, a field it used to share with the Danish state authorities. In April 2002, the Faroese authorities took over the responsibility for SAR in Faroese sea territory and established a MRCC Center in Tórshavn. A new civic security law was passed by Løgtingið (the parliament in May 2012. This article discusses micro-states’ options in the international arena; provides a brief overview of the history of Faroese security policy; and discusses the present and future challenges involved in assuring protection and rescue services for the Faroese region of the North Atlantic.

    In the research, it is argued that the targeted promotion of renewables leads to a change in the technological path dependency on the electricity market or led. The historically market depending portfolio of products in the conventional power industry will be replaced by an increasingly strong dependence on the product portfolio of Renewable Energy Sector according to this argumentation. The present work is devoted to the political explanation of the change and transition process in the electricity market. The process of policy formation in this market (especially support policies for renewable energies) will be discussed. It is examined from a public choice perspective, which political actors and instances in the past were responsible for the development and maintenance of individual policy elements. In particular, in this analysis the different private sector stakeholders in the electricity market move to center of attention. [de

    In this paper are presented the results obtained from a lab-scale investigation carried out with a system for Thermal Diagnostic Studies (STDS) aimed to study the effect of some process variables during incineration. The study has been focused on (I) gas phase dioxins formation during precursors thermal degradation, (II) thermal degradation of toxic organic compounds, (III) products of incomplete combustion (PICs) formation during thermal degradation of urban sludge spiked with toxic organics, (IV) PICs formation during process failure modes, (V) polynuclear aromatic hydrocarbons (PAHs) formation during urban sludge thermal degradation and (VI) influence of conditioning polymer on PICs emission during sludge incineration. The study about gas phase dioxins formation during precursors thermal degradation has been carried out with 2, 4, 6-trichloro- and 2, 4, 6 -tribromo-phenol that were thermal degraded at temperatures between 300 and 800 0 C in an air atmosphere. Both phenols showed the formation of the same tetra-halo-dioxin isomers that were further degraded at higher temperature. Furthermore, chlorine-containing dioxins showed higher thermal stability than bromine-containing dioxins. The study about thermal degradation of toxic organic compounds has been carried out with chlorobenzene, tetrachloroethylene and toluene that were thermal degraded at temperatures between 300 and 1000 0 C in an inert as well as air atmosphere. Results show that in all experimental conditions tetrachloroethylene and toluene are the most and less thermal stable compounds respectively. Also, all compounds are more thermal resistant during pyrolytic experiments and less thermal resistant when they are treated as a whole mixture. The study about PICs formation during thermal degradation of urban sludge spiked with toxic organics has been carried out by thermally degrading urban sludge alone or spiked with the above reported three organics at different conditions of temperature and oxygen

    Beaded channels, consisting of deepened and widened pools and connecting narrow runs, are common fluvial forms in permafrost regions. Recent studies have shown that beaded channels are very important for connecting alluvial rivers with headwater lakes allowing fish passage and foraging habitats, as well as regulating river runoff. Beaded channels are known as typical thermokarst landforms; however, there is no evidence of their origin and formative processes. Geomorphological analyzes of beaded channels have been completed in several permafrost regions including field observations of Shestakovka River in Central Yakutia. The study aims to recognize the modern exogenic processes and formative mechanisms of beaded river channels. We show that beaded channel of Shestakovka River form in the perennially frozen sand with low ice content, leading us to hypothesize that thermokarst is not the main process of formation. Due to the significant volume of water, the pools don't freeze over entirely during winters, even under harsh climatic conditions. As a result, lenses of pressurized water remain under surface ice underlain by perennially thawed sediments. The presence of thawed sediments under the pools and frozen sediments under the runs leads to uneven thermoerosion of the riverbed during floods, providing the beaded form of the channel. In addition, freezing of pools during winter leads to pressure increasing under ice cover and formation of ice mounds, which crack several times during winter leading to disturbance of riverbanks. Many 1st to 3rd order streams have a specific transitional meandering-to-beaded form resembling the shape of unconfined meandering rivers, but consisting of pools and runs. However, such channels exhibit no evidences of present-day erosion of concave banks and sediment accumulation at the convex banks as typically being observed in normally meandering rivers. Such forms of channels indicates that their formation occurred by the greater channel

    2013-07-01

    Full Text Available This contribution addresses political limits to the processing of policy problems in the United States. Our foci are the forces that limit policymakers' attention to different aspects of problems and how this affects the prospects for problem resolution. We theorize about three sets of forces: interest engagement, linkages among relevant institutions for policymaking, and partisan conflict. We show how the interplay of these forces limits efforts to address complex problems. Based on secondary accounts, we consider these underlying dynamics for ten complex problems. These include the thorny problems of the financial crisis, climate change, and health care; the persistent problems of K-12 education, drug abuse, and food safety; and the looming problems associated with critical infrastructure, the obesity epidemic, ocean health, and terrorism and extreme events. From these accounts we identify different patterns that we label fractured, allied, bureaucratic, and anemic policymaking.

    Although concerns have historically been raised about the influence of external donors on health policy process in recipient countries, remarkably few studies have investigated perspectives and experiences of domestic policymakers and advisers. This study examines donor influence at different stages of the health policy process (priority setting, policy formulation, policy implementation and monitoring and evaluation) in two aid-dependent LMICs, Cambodia and Pakistan. It identifies mechanisms through which asymmetries in influence between donors and domestic policy actors emerge. We conducted 24 key informant interviews-14 in Pakistan and 10 in Cambodia-with high-level decision-makers who inform or authorize health priority setting, allocate resources and/or are responsible for policy implementation, identifying three routes of influence: financial resources, technical expertise and indirect financial and political incentives. We used both inductive and deductive approaches to analyse the data. Our findings indicate that different routes of influence emerged depending on the stage of the policy process. Control of financial resources was the most commonly identified route by which donors influenced priority setting and policy implementation. Greater (perceived) technical expertise played an important role in donor influence at the policy formulation stage. Donors' power in influencing decisions, particularly during the final (monitoring and evaluation) stage of the policy process, was mediated by their ability to control indirect financial and political incentives as well as direct control of financial resources. This study thus helps unpack the nuances of donor influence over health policymaking in these settings, and can potentially indicate areas that require attention to increase the ownership of domestic actors of their countries' health policy processes. © The Author(s) 2017.

  19. Carbon formation and metal dusting in advanced coal gasification processes

    1997-02-01

    The product gases generated by coal gasification systems contain high concentrations of CO and, characteristically, have relatively high carbon activities. Accordingly, carbon deposition and metal dusting can potentially degrade the operation of such gasifier systems. Therefore, the product gas compositions of eight representative gasifier systems were examined with respect to the carbon activity of the gases at temperatures ranging from 480 to 1,090 C. Phase stability calculations indicated that Fe{sub 3}C is stable only under very limited thermodynamic conditions and with certain kinetic assumptions and that FeO and Fe{sub 0.877}S tend to form instead of the carbide. As formation of Fe{sub 3}C is a necessary step in the metal dusting of steels, there are numerous gasifier environments where this type of carbon-related degradation will not occur, particularly under conditions associated with higher oxygen and sulfur activities. These calculations also indicated that the removal of H{sub 2}S by a hot-gas cleanup system may have less effect on the formation of Fe{sub 3}C in air-blown gasifier environments, where the iron oxide phase can exist and is unaffected by the removal of sulfur, than in oxygen-blown systems, where iron sulfide provides the only potential barrier to Fe{sub 3}C formation. Use of carbon- and/or low-alloy steels dictates that the process gas composition be such that Fe{sub 3}C cannot form if the potential for metal dusting is to be eliminated. Alternatively, process modifications could include the reintroduction of hydrogen sulfide, cooling the gas to perhaps as low as 400 C and/or steam injection. If higher-alloy steels are used, a hydrogen sulfide-free gas may be processed without concern about carbon deposition and metal dusting.

  20. Knowledge Cluster Formation as a Science Policy in Malaysia: Lessons Learned

    2015-01-01

    Full Text Available Regional science policy aims to create productive knowledge clusters, which are central places within an epistemic landscape of knowledge production and dissemination. These so-called K-clusters are said to have the organisational capability to drive innovations and create new industries. Many governments have used cluster formation as one of their development strategies. This paper looks at Malaysia’s path towards a knowledge-based economy and offers some evidence on the current state of knowledge cluster formation in that country. If the formation of a knowledge cluster has been the government policy, what has been the result? Is there an epistemic landscape of knowledge clusters? Has the main knowledge cluster really materialised? Data collected from websites, directories, government publications and expert interviews have enabled us to construct the epistemic landscape of Peninsular Malaysia, and Penang in particular. We identify and describe several knowledge clusters with a high density of knowledge producing institutions and their knowledge workers. An analysis of the knowledge output, measured in terms of scientific publications, patents and trademarks, shows that knowledge clusters have indeed been productive – as predicted by cluster theory – although the internal working of clusters require further explanation.

    2010-09-01

    Individuals come to understand abstract constructs such as that of the 'expert' through the formation of concepts. Time and repeated opportunity for observation to support the generalisation and abstraction of the developing concept are essential if the concept is to form successfully. Development of an effective concept of the 'expert nurse' is critical for early career nurses who are attempting to integrate theory, values and beliefs as they develop their clinical practice. This study explores the use of a concept development framework in a grounded theory study of the 'expert nurse'. Qualitative. Using grounded theory methods for data collection and analysis, semi-structured interviews were conducted with registered nurses. The participants were asked to describe their concept of the 'expert nurse' and to discuss their experience of developing this. Participants reported forming their concept of the 'expert nurse', after multiple opportunities to engage with nurses identified as 'expert'. This identification did not necessarily relate to the designated position of the 'expert nurse' or assigned mentors. When the early career nurse does not successfully form a concept of the 'expert nurse', difficulties in personal and professional development including skill/knowledge development may arise. To underpin development of their clinical practice effectively, early career nurses need to be provided with opportunities that facilitate the purposive formation of their own concept of the 'expert nurse'. Formation of this concept is not well supported by the common practice of assigning mentors. Early career nurses must be provided with the time and the opportunity to individually develop and refine their concept of the 'expert nurse'. To achieve this, strategies including providing opportunities to engage with expert nurses and discussion of the process of concept formation and its place in underpinning personal judgments may be of assistance. © 2010 Blackwell Publishing

    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.

    Full Text Available Supercritical fluid extraction and expansion (SFEE patented technology combines the advantages of both supercritical fluid extraction (SFE and rapid expansion of supercritical solution (RESS with on-line coupling, which makes the nanoparticle formation feasible directly from matrix such as Chinese herbal medicine. Supercritical fluid extraction is a green separation technology, which has been developed for decades and widely applied in traditional Chinese medicines or natural active components. In this paper, a SFEE patented instrument was firstly built up and controlled by LABVIEW work stations. Stearic acid was used to verify the SFEE process at optimized condition; via adjusting the preexpansion pressure and temperature one can get different sizes of particles. Furthermore, stearic acid was purified during the SFEE process with HPLC-ELSD detecting device; purity of stearic acid increased by 19%, and the device can purify stearic acid.

    Immobilized cell technology has shown a significant promotional effect on the fermentation of alcoholic beverages such as beer, wine and cider. However, genetic, morphological and physiological alterations occurring in immobilized yeast cells impact on aroma formation during fermentation processes. The focus of this review is exploitation of existing knowledge on the biochemistry and the biological role of flavour production in yeast for the biotechnological production of aroma compounds of industrial importance, by means of immobilized yeast. Various types of carrier materials and immobilization methods proposed for application in beer, wine, fruit wine, cider and mead production are presented. Engineering aspects with special emphasis on immobilized cell bioreactor design, operation and scale-up potential are also discussed. Ultimately, examples of products with improved quality properties within the alcoholic beverages are addressed, together with identification and description of the future perspectives and scope for cell immobilization in fermentation processes.

    2017-03-01

    For over twenty years there have been calls for greater 'consumer' participation in health decision-making. While it is recognised by governments and other stakeholders that 'consumer' participation is desirable, barriers to meaningful involvement nonetheless remain. It has been suggested that the reifying of 'evidence-based policy' may be limiting opportunities for participation, through the way this discourse legitimates particular voices to the exclusion of others. Others have suggested that assumptions underpinning the very notion of the 'affected community' or 'consumers' as fixed and bounded 'policy publics' need to be problematised. In this paper, drawing on interviews (n = 41) with individuals closely involved in Australian drug policy discussions, we critically interrogate the productive techniques and constitutive effects of 'evidence-based policy' and 'consumer participation' discourses in the context of drug policy processes. To inform our analysis, we draw on and combine a number of critical perspectives including Foucault's concept of subjugated knowledges, the work of feminist theorists, as well as recent work regarding conceptualisations of emergent policy publics. First, we explore how the subject position of 'consumer' might be seen as enacted in the material-discursive practices of 'evidence-based policy' and 'consumer participation' in drug policy processes. Secondly, we consider the centralising power-effects of the dominant 'evidence-based policy' paradigm, and how resistance may be thought about in this context. We suggest that such interrogation has potential to recast the call for 'consumer' participation in health policy decision-making and drug policy processes. Copyright © 2017 Elsevier Ltd.

    Corbin, Michael R.; Vacca, William D.

    2002-12-01

    We present deep U-, V-, and I-band images of the ``ultracompact'' blue dwarf galaxy POX 186 obtained with the Planetary Camera 2 of the Hubble Space Telescope. We have also obtained a near-ultraviolet spectrum of the object with the Space Telescope Imaging Spectrograph and combine this with a new ground-based optical spectrum. The images confirm the galaxy to be extremely small, with a maximum extent of only 300 pc, a luminosity of ~10-4L*, and an estimated mass of ~107 Msolar. Its morphology is highly asymmetric, with a tail of material on its western side that may be tidal in origin. The U-band image shows this tail to be part of a stream of material in which stars have recently formed. Most of the star formation in the galaxy is, however, concentrated in a central, compact (d~10-15 pc) star cluster. We estimate this cluster to have a total mass of ~105 Msolar, to be forming stars at a rate of less than 0.05 yr-1, and to have a maximum age of a few million years. The outer regions of the galaxy are significantly redder than the cluster, with V-I colors consistent with a population dominated by K and M stars. From our analysis of the optical spectrum we find the galaxy to have a metallicity Z~=0.06 Zsolar and to contain a significant amount of internal dust [E(B-V)~=0.28] both values agree with previous estimates. While these results rule out earlier speculation that POX 186 is a protogalaxy, its morphology, mass, and active star formation suggest that it represents a recent (within ~108 yr) collision between two clumps of stars of subgalactic size (~100 pc). POX 186 may thus be a very small dwarf galaxy that, dynamically speaking, is still in the process of formation. This interpretation is supported by the fact that it resides in a void, so its morphology cannot be explained as the result of an encounter with a more massive galaxy. Clumps of stars this small may represent the building blocks required by hierarchical models of galaxy formation, and these results

    Full Text Available Language as a communication tool has an important role in human interaction. Language can be used to convey ideas, ideas, feelings, desires, and so forth to others. To be able to communicate well certainly should be able to adjust the language used. One of the main functions of communication is to maintain the continuity of the relationship between the narrator and hearer. Language is an important pillar in the formation of character, in addition to religious education and moral education. In education, teachers must have pedagogical, professional, personal, and social. Teachers who have a good competence speech acts certainly have a good and well mannered to students. In the learning process, teachers and students communicate in give and receive course materials. The learning process is certainly not only provides knowledge alone, but give the values of character to students. In this case, the teacher must have a principle that must be controlled properly, correctly and precisely. Thus, teachers are expected to master the communication and understanding the principles of politeness in speaking well and correctly. The goal is a description of a form of politeness in the learning process. This research is a descriptive study which seeks to describe a form of politeness in the learning process. Data collection method used is the method refer to the data collection techniques are 1 recording technique using a tape recorder, and 2 technical note on the data card. Furthermore, methods of data analysis using pragmatic frontier.

    1 - Description of program or function: RELABEL labels a ENDF/B pre-processing program so that statement labels are in increasing order in increments of 10 within each routine, and cards are identified in columns 73-80 by three alphanumeric characters in columns 73-75 and sequence numbers in columns 76-80 in increments of 10. IAEA1314/10: This version include the updates up to January 30, 2007. Changes in ENDF/B-VII Format and procedures, as well as the evaluations themselves, make it impossible for versions of the ENDF/B pre-processing codes earlier than PREPRO 2007 (2007 Version) to accurately process current ENDF/B-VII evaluations. The present code can handle all existing ENDF/B-VI evaluations through release 8, which will be the last release of ENDF/B-VI. Modifications from previous versions: Relabel VERS. 2007-1 (JAN. 2007): No change since March 2004 version 2 - Method of solution: 3 - Restrictions on the complexity of the problem: RELABEL is designed to maintain ENDF/B processing programs which use a restricted set of FORTRAN statements. As such, this program is not completely general

    As a result of the termination of the Yucca Mountain Project, the United States Department of Energy (DOE) has started to explore various alternative avenues for the disposition of used nuclear fuel and nuclear waste. The overall scope of the investigation includes temporary storage, transportation issues, permanent disposal, various nuclear fuel types, processing alternatives, and resulting waste streams. Although geologic disposal is not the only alternative, it is still the leading candidate for permanent disposal. The realm of geologic disposal also offers a range of geologic environments that may be considered, among those clay shale formations. Figure 1-1 presents the distribution of clay/shale formations within the USA. Clay rock/shale has been considered as potential host rock for geological disposal of high-level nuclear waste throughout the world, because of its low permeability, low diffusion coefficient, high retention capacity for radionuclides, and capability to self-seal fractures induced by tunnel excavation. For example, Callovo-Oxfordian argillites at the Bure site, France (Fouche et al., 2004), Toarcian argillites at the Tournemire site, France (Patriarche et al., 2004), Opalinus clay at the Mont Terri site, Switzerland (Meier et al., 2000), and Boom clay at Mol site, Belgium (Barnichon et al., 2005) have all been under intensive scientific investigations (at both field and laboratory scales) for understanding a variety of rock properties and their relations with flow and transport processes associated with geological disposal of nuclear waste. Clay/shale formations may be generally classified as indurated and plastic clays (Tsang et al., 2005). The latter (including Boom clay) is a softer material without high cohesion; its deformation is dominantly plastic. For both clay rocks, coupled thermal, hydrological, mechanical and chemical (THMC) processes are expected to have a significant impact on the long-term safety of a clay repository. For

    Banin, Amos

    1992-01-01

    The mineralogical nature of Mars soil is far from being understood, nor are the formation time and weathering processes known. Quantitatively, the two major mineral-forming elements in Mars soil are silicon and iron, constituting 44 and 19 percent of the soils as SiO4 and Fe2O3, respectively. The silicate phases have been studied only briefly, mostly because of their limited spectral fingerprinting in the VIS and NIR. Much attention was given to the iron minerals in the soil, due to their pronounced absorption in the VIS and NIR, making them easily detectable by telescopic observations. The available information on Mars soil mineralogy, mostly obtained by remote sensing, is reviewed, and it is hypothesized that it leads to the suggestion that nanophase short-range-order (amorphous) phases of the silicates and iron oxides abound in the soil.

    Lessner, G.

    1998-01-01

    A scenario of galaxy formation is put forward which is a process of sudden condensation just after recombination. It is essentially based on the fact that the cosmic-matter gas after recombination is a general relativistic Boltzmann gas which runs within a few 10 6 years into a tate very close to collision-dominated equilibrium. The mass spectrum of axially symmetric condensation 'drops' extends from the lower limit M ≅ 10 5 M to the upper limit M ≅ 10 12 M. The lower-limit masses are spheres whereas the upper-limit masses are thin pancakes. These pancakes contract within a time of about 2.5 · 10 9 y to rotating spiral galaxies with ordinary proportions. In this final state they have a redshift z ≅ 3. At an earlier time during their contraction they are highly active and are observed with a redshift z ≅ 5

    Full Text Available Agenda setting is the process by which problems and alternative solutions gain or lose public attention (Birkland T. (2007, p.63; Werner J. and Wegrich K. (2007, p.46.. The main factor that determine an issue that it could become a priority, drawing the attention of decision makers, the public, reaching for it to become part of the agenda are: “Window of Opportunity”, which is a strategy used by less powerful groups, which are benefiting from the fact that powerful groups in certain situations may lose control of the agenda, they manage this circumstances to make their case to the priority. Another factor are the “Focus Event” that emphasizes the fact that unexpected events that shock the public opinion, as were the cases of corruption of officials, case “Snowden” or 11 September in the USA, affecting an issue that directly lead the decision-making agenda. Advocacy coalitions, is a form that use less powerful groups by joining on the basis of certain principles, values, beliefs they have about a particular issue. This alliance of values, resources and coordination of actions helps to advance the issue becoming a priority. “Venue shop” as a factor that aims to reach groups through institutions, be heard, be able to attract the attention of decision makers, also using the media as a very important factor nowadays for sensitizing public opinion on the issue and influence in order to become a priority issue. “Policy network” has come as a need of developing a relationship between government and the private sector, thus forming a power dependency relationship mainly the exchange of resources and thereby influencing the political agenda on particular issues. Therefore in this article I will try to argue that these factors affect in various ways becoming determinant that the issue be the priority on the decision agenda. Also, I can say that after the development of the analysis, I think that the two factors have a greater influence

    1994-03-01

    Sandia National Laboratories has designed and built an electrical test system which fulfills a requirement to quickly, accurately and precisely measure the resistance of conductors formed on Printed Wiring Board (PWB) substrates. This requirement stems from the need to measure small variations in conductors and thus to determine the source of the variations. With this test technology, experiments can be conducted with new materials, equipment, and processes in a timely and scientific manner. Conductor formation processes can be optimized for both conductor yield and uniformity, and process equipment can be fine-tuned prior to processing product to ensure that conductor attributes fulfill requirements. Significant resources have been spent by Sandia National Laboratories and Texas Instruments modifying commercially available two-probe testers. AT&T has built a two-probe tester and obtained a commercially available ``bed-of-nails`` test system. The two-probe systems have limitations in speed and precision; the ``bed-of-nails`` system has proved to be superior to the two-probe designs but is expensive, and lacks test pattern flexibility and ease of use. Due to the need to establish a testing technology which meets the requirements of Sandia National Laboratories and the National Center for Manufacturing Sciences PWB Consortium Imaging Team (current Imaging Team members; AT&T, Texas Instruments, AlliedSignal, IBM, and Sandia National Laboratories), a prototype test system was designed and built by Sandia. This paper will discuss the design and performance of the test system and the results of a comparison to other test systems.

    2008-01-01

    Public policies impact the amount of physical activity (PA) that children receive at school. These policies are of interest because overweight and obesity among Canadian children have grown at significant rates, and increasing PA among children is one way to reverse this trend. This research investigates the public policy processes that have resulted in Alberta's education system adopting in-school daily physical activity (DPA) and not supporting walk-to-school (WTS) initiatives. Using the policy process described by Kingdon and others as a conceptual framework, this research reviews literature and documents on public policy relating to PA in schools and interviews key individuals (N = 20) to identify the policy-related facilitators and barriers in Alberta, Canada to increasing PA in school-aged children. DPA was mandated because Kingdon's three policy streams (problem, solution and politics) became joined or linked. DPA was the most viable solution because literature supports and teachers believe in the educational benefits of PA. As well, a physician with personal beliefs about the benefits of PA became the minister of education and coupled the solution with the political stream through his ministerial power. Reasons that WTS programs have not become school or health policy include advocacy led by politically weak organizations, lack of a supportive policy entrepreneur and poor saliency among educators. This research illuminates the inner workings of the policy process shaping PA in schools, identifying the unseen forces of the policy process that move issues forward. The findings provide valuable insight for building other healthy public policies.

  10. Computer Simulation of the Solidification Process Including Air Gap Formation

    Directory of Open Access Journals (Sweden)

    Skrzypczak T.

    2017-12-01

    Full Text Available The paper presents an approach of numerical modelling of alloy solidification in permanent mold and transient heat transport between the casting and the mold in two-dimensional space. The gap of time-dependent width called "air gap", filled with heat conducting gaseous medium is included in the model. The coefficient of thermal conductivity of the gas filling the space between the casting and the mold is small enough to introduce significant thermal resistance into the heat transport process. The mathematical model of heat transport is based on the partial differential equation of heat conduction written independently for the solidifying region and the mold. Appropriate solidification model based on the latent heat of solidification is also included in the mathematical description. These equations are supplemented by appropriate initial and boundary conditions. The formation process of air gap depends on the thermal deformations of the mold and the casting. The numerical model is based on the finite element method (FEM with independent spatial discretization of interacting regions. It results in multi-mesh problem because the considered regions are disconnected.

    Based on the data from an integrated study by a multidisciplinary group on the Jilin meteorite, we discuss the following aspects concerning its formation and evolution: (1) The fractionation-condensation of the solar nebula was examined based on the condensation and solidification age and the mineral composition of the Jilin meteorite. (2) The thermometamorphic history of the Jilin parent body was discussed based on the data on the loss of rare gases, the chemical composition of the whole rock, the self-purification of rare-earth elements and the composition stability of olivine and orthopyroxene. (3) The cooling process of the Jilin parent body was analyzed according to the Ni content and the width of taenite, and the retentivity of argon and fission tracks in the minerals. (4) The breakup of the Jilin parent body and its cosmic ray irradiation history: Based on the measurements of the cosmogenic nuclides as He 3 , Ne/sup 20,21,22/, Ar 38 , Na 22 , Al 26 , Mn 54 , Mn 53 , Co 60 etc., a two-stage model of the irradiation history of the Jilin meteorite was proposed. From the data on the Jilin meteorite parent body of the first stage (the age = 10--11 MY and r = 10 m) and that of the second stage (the age = 0.3--0.5 MY and r = 80--90 cm). The relative positions of samples in the parent body, their burial depths as well as the post-atmospheric loss by ignition were determined. (5) The falling process of the Jilin meteorite: The orbits of the Jilin meteor in the solar system and in the atmosphere, and its falling process were discussed

    Assessing the impact that research evidence has on policy is complex. It involves consideration of conceptual issues of what determines research impact and policy change. There are also a range of methodological issues relating to the question of attribution and the counter-factual. The dynamics of SRH, HIV and AIDS, like many policy arenas, are partly generic and partly issue- and context-specific. Against this background, this article reviews some of the main conceptualisations of research impact on policy, including generic determinants of research impact identified across a range of settings, as well as the specificities of SRH in particular. We find that there is scope for greater cross-fertilisation of concepts, models and experiences between public health researchers and political scientists working in international development and research impact evaluation. We identify aspects of the policy landscape and drivers of policy change commonly occurring across multiple sectors and studies to create a framework that researchers can use to examine the influences on research uptake in specific settings, in order to guide attempts to ensure uptake of their findings. This framework has the advantage that distinguishes between pre-existing factors influencing uptake and the ways in which researchers can actively influence the policy landscape and promote research uptake through their policy engagement actions and strategies. We apply this framework to examples from the case study papers in this supplement, with specific discussion about the dynamics of SRH policy processes in resource poor contexts. We conclude by highlighting the need for continued multi-sectoral work on understanding and measuring research uptake and for prospective approaches to receive greater attention from policy analysts.

    Directory of Open Access Journals (Sweden)

    A.A. Bakr

    2015-03-01

    Full Text Available Conventional water-softening processes usually involve the exchange of Na+ ions for Ca2+ and Mg2+ using commercial or synthesized ion exchangers. The differences in chemical compositions of the ooids can be attributed to the formation in different environments. In this paper, ooid grains form inside assembled semi-pilot softening unit through a continuous chemical process involving reaction between bicarbonate ions and added lime using natural seawater. Our sample of Mediterranean seawater has low Mg2+/Ca2+ ratio (1.98% within the range chemically favorable for precipitation of low-Mg calcite ooids. Precipitation of calcite occurs around pure quartz sand grains which act as nucleation points (the bed required for sand vessel is 1.65 l. The shape of the sand grains controls the overall external morphology of the resulting ooids; they vary in size from 0.5 to 3.0 mm and have a high degree of polish due to surface abrasion caused by continuous agitation inside the softening system. Calcite ooid grains (1.53 kg formed within the seawater-softening unit every 18 days have many of the ooid features formed in marine environments. Ooids grow to a significant size, at a rate of about 0.17 mm of one layer thickness per day inside the softening unit. The average weight percent of calcite precipitate is 35.48% after 18 days, at 10 °C, 60 l/min and pH 9.0. The pellets comprise mainly CaCO3 and SiO2 and some metal ions which may substitute for calcium ions in calcite are present only in trace amounts of the total composition.

    1998-01-01

    The aim of this work is to develop an algorithm to simulate the radiographic image formation process using volumetric anatomical data of the patient, obtained from 3D diagnostic CT images. Many applications, including radiographic driven surgery, virtual reality in medicine and radiologist teaching and training, may take advantage of such technique. The designed algorithm has been developed to simulate a generic radiographic equipment, whatever oriented respect to the patient. The simulated radiography is obtained considering a discrete number of X-ray paths departing from the focus, passing through the patient volume and reaching the radiographic plane. To evaluate a generic pixel of the simulated radiography, the cumulative absorption along the corresponding X-ray is computed. To estimate X-ray absorption in a generic point of the patient volume, 3D interpolation of CT data has been adopted. The proposed technique is quite similar to those employed in Ray Tracing. A computer designed test volume has been used to assess the reliability of the radiography simulation algorithm as a measuring tool. From the errors analysis emerges that the accuracy achieved by the radiographic simulation algorithm is largely confined within the sampling step of the CT volume. (authors)

    Although solution-plasma processing enables room-temperature synthesis of nanocarbons, the underlying mechanisms are not well understood. We investigated the routes of solution-plasma-induced nanocarbon formation from hexane, hexadecane, cyclohexane, and benzene. The synthesis rate from benzene was the highest. However, the nanocarbons from linear molecules were more crystalline than those from ring molecules. Linear molecules decomposed into shorter olefins, whereas ring molecules were reconstructed in the plasma. In the saturated ring molecules, C-H dissociation proceeded, followed by conversion into unsaturated ring molecules. However, unsaturated ring molecules were directly polymerized through cation radicals, such as benzene radical cation, and were converted into two- and three-ring molecules at the plasma-solution interface. The nanocarbons from linear molecules were synthesized in plasma from small molecules such as C2 under heat; the obtained products were the same as those obtained via pyrolysis synthesis. Conversely, the nanocarbons obtained from ring molecules were directly synthesized through an intermediate, such as benzene radical cation, at the interface between plasma and solution, resulting in the same products as those obtained via polymerization. These two different reaction fields provide a reasonable explanation for the fastest synthesis rate observed in the case of benzene.

    Full Text Available The EU represents a transforming educational space, where national and supranational boundaries in educational governance are becoming blurred. The EU has become an  important actor in educational governance and an important arena for policy learning and transfer. This paper explores how the process of reshaping the educational space manifests itself in the process of the Europeanization of VET policy in the case of Estonia. In Estonia, this process was followed by the growth of executive VET institutions and has developed from rather uncritical initial policy transfer to more active learning from the EU, although conformism can still be seen in cases of the introduction of standardizing policy tools.

    Full Text Available This work analyzes the main orientation of educational policies designed and implemented in the region within the so called “second generation state reforms”, in a context of growing inequality, fragmentation and social polarization. These reforms have been based, on the one hand, on the Knowledge Society Paradigm and the demand for competitive insertion in the global economy, and on the other, on strategies for poverty reduction and containment aimed at guaranteeing democratic governance in Latin American countries. In this vein, new forms of government and management of educational systems have been designed and implemented, that can be analyzed as new ways to regulate educational policy and action.

    Full Text Available Abstract Background Mental illnesses are increasingly recognised as a leading cause of disability worldwide, yet many countries lack a mental health policy or have an outdated, inappropriate policy. This paper explores the development of appropriate mental health policies and their effective implementation. It reports comparative findings on the processes for developing and implementing mental health policies in Ghana, South Africa, Uganda and Zambia as part of the Mental Health and Poverty Project. Methods The study countries and respondents were purposively selected to represent different levels of mental health policy and system development to allow comparative analysis of the factors underlying the different forms of mental health policy development and implementation. Data were collected using semi-structured interviews and document analysis. Data analysis was guided by conceptual framework that was developed for this purpose. A framework approach to analysis was used, incorporating themes that emerged from the data and from the conceptual framework. Results Mental health policies in Ghana, South Africa, Uganda and Zambia are weak, in draft form or non-existent. Mental health remained low on the policy agenda due to stigma and a lack of information, as well as low prioritisation by donors, low political priority and grassroots demand. Progress with mental health policy development varied and respondents noted a lack of consultation and insufficient evidence to inform policy development. Furthermore, policies were poorly implemented, due to factors including insufficient dissemination and operationalisation of policies and a lack of resources. Conclusions Mental health policy processes in all four countries were inadequate, leading to either weak or non-existent policies, with an impact on mental health services. Recommendations are provided to strengthen mental health policy processes in these and other African countries.

  1. Political processes and variation in renewable energy policies between U.S. states

    Science.gov (United States)

    Vasseur, Michael

    Over the past forty years federal efforts at renewable energy policy in the United States have been fragmented and are largely stalled. This is much different from U.S. states, which enact a diverse array of renewable energy policies. What factors explain this subnational variation? Addressing this question requires moving past the standard model of binary policy adoption that dominates studies of renewable energy policy. In its place I provide analyses of multifaceted policy outcomes, and also include predictors from a more inclusive view of politics than the standard economic and political interest factors. These additions to the standard energy policy model shed light not just on when states take policy action, but also on the content of the policies states ultimately adopt. In this dissertation I argue that different combinations of state-level political and economic characteristics influence policy adoption and policy content, a fact that is obscured by analysis of only binary policy action. I demonstrate this through three empirical projects that utilize an original longitudinal dataset and a variety of quantitative methods. The first project examines the diffusion of two varieties of a single regulatory policy instrument within a political context. I demonstrate that, contrary to most diffusion studies, policy adoption should be thought of as a multifaceted process, with separate factors determining the impetus for action and others shaping the content of the policy. My second project examines the role of economic, political, institutional, and cultural factors on a state's portfolio of policies. This work extends findings from prior literature on tax policies and incorporates institutional and cultural accounts of policy adoption into the study of renewable energy policy. I show that state economic and political factors, the predictors in traditional energy policy models, predict policy action but not policy content. Instead it is a state's cultural context

    Polycrystalline diamond aggregates (framesites) contain silicates of eclogitic and peridotitic affinity (e.g. Kurat and Dobosi, 2000). The minerals occur mostly in interstices and are intimately intergrown with the diamonds, indicating contemporaneous crystallization within the diamond stability field in the Earth's mantle. In addition to silicates, rarer phases such as Fe-carbide can sometimes be found in framesites that record unusually low local oxygen fugacity at the time of their formation (Jacob et al., 2004). Furthermore, while most gem-sized diamonds have old, often Archaean formation ages, some polycrystalline diamond aggregates have been shown to form directly preceding the kimberlite eruption (Jacob et al., 2000). Thus, these samples may provide a unique source of information on the nature and timing of small scale processes that lead to diamond formation and complement evidence from gem-sized diamonds. Here, we present a study of micro- and nano-inclusions in diamonds from a polycrystalline diamond aggregate (framesite) from the Orapa Mine (Botswana) and combine results from TEM/FIB analyses with high-resolution computerized micro-tomography (HR-µCT) and electron microprobe analyses to further constrain the formation of diamond in the Earth's mantle. Results In total, 14 microinclusions from fifteen FIB foils were investigated. Micro- and nano-inclusions identified by TEM were smaller than 1µm down to ca. 50nm in size, and are both monomineralic and multi-phase. The cavities are often lath-shaped and oriented parallel to each other; many show lattice dislocations in the surrounding diamond. In addition, inclusions are found along open cracks within the diamond single crystals. Mineral phases in the microinclusions comprise rutile, omphacite and a FeS phase (pyrrhotite). The multiphase inclusions most often consist of cavities that are only partly occupied (less than 50% of the total space), suggesting that the empty space was originally filled by a

    2017-11-12

    This study explored factors that shaped the development of Australia's Health Star Rating system for front-of-pack labelling (FoPL) on packaged foods and whether insights could be drawn from this experience to inform the development of global FoPL standards. Ten individual semi-structured interviews were conducted with public health or consumer advocates, academics in the field of nutrition labelling and policy, a food industry employee, and Australian public servants. Thematic analysis was undertaken, guided by Kingdon's Multiple Streams Framework, to identify factors which shaped Australian and international FoPL policy processes. Senior Australian bureaucrats played the policy entrepreneur role to facilitate the development of the Health Star Rating system. The public health and consumer advocacy groups formed an alliance to counter-balance the influence of the food industry in the Health Star Rating development process. Public health and consumer groups have less influence at Codex Alimentarius, where policy-making is constrained by political alliances and consensus voting structures. Strong leadership, policy entrepreneurship and a coherent alliance between public health and consumer groups enabled the development of a FoPL system in Australia and could contribute to advancing FoPL standards at the international level. © 2017 Dietitians Association of Australia.

  5. Dissolving decision making? Models and their roles in decision-making processes and policy at large.

    Science.gov (United States)

    Zeiss, Ragna; van Egmond, Stans

    2014-12-01

    This article studies the roles three science-based models play in Dutch policy and decision making processes. Key is the interaction between model construction and environment. Their political and scientific environments form contexts that shape the roles of models in policy decision making. Attention is paid to three aspects of the wider context of the models: a) the history of the construction process; b) (changes in) the political and scientific environments; and c) the use in policy processes over longer periods of time. Models are more successfully used when they are constructed in a stable political and scientific environment. Stability and certainty within a scientific field seems to be a key predictor for the usefulness of models for policy making. The economic model is more disputed than the ecology-based model and the model that has its theoretical foundation in physics and chemistry. The roles models play in policy processes are too complex to be considered as straightforward technocratic powers.

    Arctic ice cloud formation during winter is poorly understood mainly due to lack of observations and the remoteness of this region. Their influence on Northern Hemisphere weather and climate is of paramount importance, and the modification of their properties, linked to aerosol-cloud interaction processes, needs to be better understood. Large concentration of aerosols in the Arctic during winter is associated to long-range transport of anthropogenic aerosols from the mid-latitudes to the Arctic. Observations show that sulphuric acid coats most of these aerosols. Laboratory and in-situ measurements show that at cold temperature (coating lowers the freezing point and deactivates ice nuclei (IN). Therefore, the IN concentration is reduced in these regions and there is less competition for the same available moisture. As a result, large ice crystals form in relatively small concentrations. It is hypothesized that the observed low concentration of large ice crystals in thin ice clouds is linked to the acidification of aerosols. Extensive measurements from ground-based sites and satellite remote sensing (CloudSat and CALIPSO) reveal the existence of two types of extended optically thin ice clouds (TICs) in the Arctic during the polar night and early spring. The first type (TIC-1) is seen only by the lidar, but not the radar, and is found in pristine environment whereas the second type (TIC-2) is detected by both sensors, and is associated with high concentration of aerosols, possibly anthropogenic. TIC-2 is characterized by a low concentration of ice crystals that are large enough to precipitate. To further investigate the interactions between TICs clouds and aerosols, in-situ, airborne and satellite measurements of specific cases observed during the POLARCAT and ISDAC field experiments are analyzed. These two field campaigns took place respectively over the North Slope of Alaska and Northern part of Sweden in April 2008. Analysis of cloud type can be done from these

    Recent mass shootings have prompted a national dialogue around mental illness and gun policy. To advance an evidence-informed policy agenda on this controversial issue, we formed a consortium of national gun violence prevention and mental health experts. The consortium agreed on a guiding principle for future policy recommendations: restricting firearm access on the basis of certain dangerous behaviors is supported by the evidence; restricting access on the basis of mental illness diagnoses is not. We describe the group's process and recommendations.

    2011-02-01

    Previous studies demonstrated an upregulation of pyruvate formate lyase (Pfl) and NAD-dependent formate dehydrogenase (Fdh) in Staphylococcus aureus biofilms. To investigate their physiological role, we constructed fdh and pfl deletion mutants (Δfdh and Δpfl). Although formate dehydrogenase activity in the fdh mutant was lost, it showed little phenotypic alterations under oxygen-limited conditions. In contrast, the pfl mutant displayed pleiotropic effects and revealed the importance of formate production for anabolic metabolism. In the pfl mutant, no formate was produced, glucose consumption was delayed, and ethanol production was decreased, whereas acetate and lactate production were unaffected. All metabolic alterations could be restored by addition of formate or complementation of the Δpfl mutant. In compensation reactions, serine and threonine were consumed better by the Δpfl mutant than by the wild type, suggesting that their catabolism contributes to the refilling of formyl-tetrahydrofolate, which acts as a donor of formyl groups in, e.g., purine and protein biosynthesis. This notion was supported by reduced production of formylated peptides by the Δpfl mutant compared to that of the parental strain, as demonstrated by weaker formyl-peptide receptor 1 (FPR1)-mediated activation of leukocytes with the mutant. FPR1 stimulation could also be restored either by addition of formate or by complementation of the mutation. Furthermore, arginine consumption and arc operon transcription were increased in the Δpfl mutant. Unlike what occurred with the investigated anaerobic conditions, a biofilm is distinguished by nutrient, oxygen, and pH gradients, and we thus assume that Pfl plays a significant role in the anaerobic layer of a biofilm. Fdh might be critical in (micro)aerobic layers, as formate oxidation is correlated with the generation of NADH/H(+), whose regeneration requires respiration.

    Full Text Available Vietnam was one of the first countries to introduce the National REDD+ (Reduced Emissions from Deforestation and Forest Degradation Action Program in 2012. The country has recently revised the Program to aim for a more inclusive 2016–2020 strategy and a vision to 2030. This study explores how Vietnam policy actors view REDD+ policy development and their influence in these processes. The results can contribute to the discussion on how policy actors can effectively influence policy processes in the evolving context of REDD+ and in the types of political arrangements represented in Vietnam. We examined the influence of state and non-state actors on the 2012 National REDD+ Action Program (NRAP processes, and explored factors that may have shaped this influence, using a combination of document analysis and semi-structured interviews with 81 policy actors. It was found that non-state actors in REDD+ are still on the periphery of decision making, occupying “safe” positions, and have not taken either full advantage of their capacities, or of recent significant changes in the contemporary policy environment, to exert stronger influence on policy. We suggest that REDD+ policy processes in Vietnam need to be revitalized with key actors engaging collectively to promote the possibilities of REDD+ within a broader view of social change that reaches beyond the forestry sector.

    2012-09-01

    There has been an increasing effort across Europe to develop national policies in food and nutrition during the last decade. However, little is known about how public health nutrition issues get on the public health agenda and the roles individuals have when these agendas are being set. The aims of this study were to scrutinise the development process of the Slovenian national food and nutrition policy, and to identify the roles and functions of individuals who have contributed to that process. This study undertook a qualitative approach. Data collection included 18 semi-structured interviews between 2007 and 2011, and grey and scientific literature search. Text analysis was based on Kingdon's streams model, which involved highlighting the relationship between problem identification, policy solutions and political opportunities. Data were coded to identify the roles and functions of individuals participating in the agenda-setting process. The analysis showed that the opportunity for the Slovenian food and nutrition policy to be developed was largely explained by a change in political circumstances, namely the accession of Slovenia to the European Union and the Common Agricultural Policy. Individuals with experience in policy development were identified because of their analytical, strategic and policy entrepreneurial skills. The analyst was responsible for communicating the key nutrition issues to policy-makers, the strategist joined international networks and promoted policy solutions from international experts including the World Health Organization, and the policy entrepreneur took advantage of the political situation to enlist the participation of previous opponents to a national nutrition policy. This study found that individuals, their roles and skills, played an important role in the development of the Slovenian National Food and Nutrition Policy. The roles and functions of these individuals, which are identified in this study, may assist future endeavours

    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

    Full Text Available Clause is devoted to an actual problem of decrease in negative consequences of technological development of key economic branches of the industry at a regional level. During social and economic transformations to Russia to the beginning of 90th years XX of a century there has been begun complex process of re-structuring of key economic branches of the industry, including technological, social and economic transformations. During re-structuring by one of key directions of the decision of existing social problems there is a formation of effective policy of support of small business at a regional and local level. Creation of favorable conditions for development of small business allows for short time and at rather low expenses to smooth disproportions of social and economic development of territories arising at re-structuring. Flexibility inherent in small business, mobility and adaptibility to changeable market conditions can promote the decision of problems of social stability, maintenance of employment and saturation of the consumer market. Creation of the enterprises of small business on the basis of local natural-economic resources raises social and economic potential of industrial territories.

    What motivates changes in energy policy? Typically, the process begins with a notable exogenous event, a shock. Often, the shock leads to what is perceived to be a crisis. This review essay surveys theories of crisis policymaking from the social science literature and considers their application to changes in energy policy. Two cases — one from the U.S., the other from Germany — are examined in more detail from the standpoint of the theories discussed. Suggestions are made for improving energy policy analysis in the future. - Highlights: • An analysis of the idea of “crisis” and its application to energy. • A review of theories and models of the policy process and of policy change. • Theory applied to two energy cases. • Suggestion as to how the analysis of energy policymaking might be approached in the future

    2015-05-01

    During the last 20 years Lao People's Democratic Republic has successfully developed and adopted some 30 health policies, strategies, decrees and laws in the field of health. Still, the implementation process remains arduous. This article aims at discussing challenges of health policy development and effective implementation by contextualizing the policy evolution over time and by focusing particularly on the National Drug Policy and the Health Care Law. Special attention is given to the role of research in policymaking. The analysis was guided by the conceptual framework of policy context, process, content and actors, combined with an institutional perspective, and showed that effective implementation of a health policy is highly dependent on both structures and agency of those involved in the policy process. The National Drug Policy was formulated and adopted in a short period of time in a resource-scarce setting, but with dedicated policy entrepreneurs and support of concerned international collaborators. Timely introduction of operational health systems research played a crucial role to support the implementation, as well as the subsequent revision of the policy. The development of the Health Care Law took several years and once adopted, the implementation was delayed by institutional legacies and issues concerning the choice of institutional design and financing, despite strong support of the law among the policymakers. Among many factors, timing of the implementation appeared to be of crucial importance, in combination with strong leadership. These two examples show that more research, that problematizes the complex policy environment in combination with improved communication between researchers and policymakers, is necessary to inform about measures for effective implementation. A way forward can be to strengthen the domestic research capacity and the international research collaboration regionally as well as globally. Published by Oxford University Press

    Spina bifida is a serious and largely preventable neural tube birth defect and an important cause of mortality and lifelong disability. The People and Organizations United for Spina Bifida and Hydrocephalus (PUSH!) Global Alliance was formed in 2014 to provide a common platform for various organizations worldwide to raise the visibility of spina bifida and hydrocephalus. In its formative phase, the alliance recognized that in order to accelerate surveillance, prevention, and care for these conditions, there was a need to provide an evidence-based assessment of how nations are performing in specific areas. In this paper, we describe the impetus for, and the process of, developing country-level scorecards for spina bifida surveillance, prevention and care. The PUSH! Executive Committee formulated a comprehensive list of six actionable indicators measuring availability of published studies on population-based folate studies; surveillance of prevalence and mortality; prevention-based policies; access to care; and quality of life associated with spina bifida. Rubrics were developed to score each country on the aforementioned indicators. Country scores were pooled across each indicator and the composite scores ranged between zero and three if there was a need for improvement, four and five if they were in good standing, or six for an excellent status. The scorecard included country-specific recommendations assimilated from the literature and published guidelines to aid policy makers in accelerating surveillance and prevention, and improving the care and quality of life indicators. For comparison, country-level scorecards were grouped by WHO-regions. Score cards were made available publicly through the website "www.pu-sh.org". Copyright © 2017 Elsevier Inc.

    Goossens, Adriaan J.M.; Basten, Rob J.I.

    2015-01-01

    In this paper we investigate maintenance policy selection (MPS) through the use of the Analytic Hierarchy Process (AHP). A maintenance policy is a policy that dictates which parameter triggers a maintenance action. In practice, selecting the right maintenance policy appears to be a difficult decision. We investigate MPS for naval ships, but our results have wider applicability. For our study we cooperate with the owner and operator of the ships, as well as with a shipbuilder and an original equipment manufacturer of naval ships. We apply a structured five step approach to obtain the relevant criteria that may make one policy preferable over another. The criteria are drawn from both literature and a series of interviews at several navy related companies and are structured into a hierarchy of criteria usable with the AHP. Additionally, we organize three workshops at the three different companies to test the AHP-based MPS approach in practice. We conclude that the AHP is well suited for maintenance policy selection in this broad setting, and that it provides a structured and detailed approach for MPS. Adding to that, it facilitates discussions during and after the sessions, creating a better understanding of the policy selection process. - Highlights: • We use the Analytic Hierarchy Process (AHP) for maintenance policy selection (MPS). • Using both interviews and case studies from the literature, we construct a hierarchy. • In sessions at 3 companies, we find that 1 hierarchy can be used for multiple assets. • The AHP creates a better understanding of the maintenance policy selection process. • Our work is on naval ships, but our approach and findings have wider applicability

    Full Text Available This paper considers environmental and economic aspects of inclusion of man-made iron and steel resources. Theoretical approaches to the concept of damage from environmental pollution caused by activities of metallurgical enterprises are investigated, in particular, the problem of disposal. The importance of categories of damage in the development of economic instruments to address environmental problems of industrial waste storage is emphasized. The total damage from pollution is regarded as a synergistic set of economic and environmental damage. Thus, the basic criterion in determining the economic damage appears to be the cost of resources needed to compensate for the damage to the environment - the time required for self-healing of the system. The possibilities of using waste steel from electric melting production as feedstock for the production of zinc are discussed. An assessment of the effectiveness of the investment project to engage in the processing of industrial wastes in Chelyabinsk Zinc Plant is made. The high efficiency of commercial and financial viability of the proposed technology for processing zinc-containing industrial wastes is shown. Calculations are performed to assess the damage avoided as a result of the processing of man-made structures, which is composed of damage prevention and land degradation and damage from pollution by chemicals. It is shown that cost-effective processing of man-made iron and steel resources is essential to address environmental problems of the metallurgical complex.

    Parkinson's disease (PD) is characterized by a degeneration of nigrostriatal dopaminergic cells, resulting in dopamine depletion. This depletion is counteracted through dopamine replacement therapy (DRT). Dopamine has been suggested to affect novelty processing and memory, which suggests that these processes are also implicated in PD and that DRT could affect them. To investigate word learning and novelty processing in patients with PD as indexed by the P2 and P3 event-related potential components, and the role of DRT in these processes. 21 patients with PD and 21 matched healthy controls were included. Patients with PD were tested on and off DRT in two sessions in a counterbalanced design, and healthy controls were tested twice without intervention. Electroencephalogram (EEG) was measured while participants performed a word learning Von Restorff task. Healthy controls showed the typical Von Restorff effect, with better memory for words that were presented in novel fonts, than for words presented in standard font. Surprisingly, this effect was reversed in the patients with PD. In line with the behavioral findings, the P3 was larger for novel than for standard font words in healthy controls, but not in patients with PD. For both groups the P2 and P3 event-related components were larger for recalled versus forgotten words. DRT did not affect these processes. Learning of novel information is compromised in patients with PD. Likewise, the P2 and P3 components that predict successful memory encoding are reduced in PD patients. This was true both on and off DRT, suggesting that these findings reflect abnormalities in learning and memory in PD that are not resolved by dopaminergic medication. Copyright © 2014 Elsevier Ltd.

    Defects caused by particulate contamination are an important concern in the fabrication of thin film products. Often, magnetron sputtering processes are used for this purpose. Particle contamination can cause electrical shorting, pin holes, problems with photolithography, adhesion failure, as well as visual and cosmetic defects. Particle contamination generated during thin film processing can be detected using laser light scattering, a powerful diagnostic technique that provides real-time, {ital in-situ} imaging of particles > 0.3 {mu}m in diameter. Using this technique, the causes, sources and influences on particles in plasma and non-plasma and non-plasma processes may be independently evaluated and corrected. Several studies employing laser light scattering have demonstrated both homogeneous and heterogeneous causes of particle contamination. In this paper, we demonstrate that the mechanisms for particle generation, transport and trapping during magnetron sputter deposition are different from the mechanisms reported in previously studied plasma etch processes. During magnetron sputter deposition, one source of particle contamination is linked to portions of the sputtering target surface exposed to weaker plasma density. In this region, film redeposition is followed by filament or nodule growth and enhanced trapping which increases filament growth. Eventually the filaments effectively ``short circuit`` the sheath, causing high currents to flow through these features. This, in turn, causes heating failure of the filament fracturing and ejecting the filaments into the plasma and onto the substrate. Evidence of this effect has been observed in semiconductor (IC) fabrication and storage disk manufacturing. Discovery of this mechanism in both technologies suggests that this mechanism may be universal to many sputtering processes.

  1. Using Argument Visualization to Enhance e-Participation in the Legislation Formation Process

    Science.gov (United States)

    Loukis, Euripidis; Xenakis, Alexandros; Tseperli, Nektaria

    Most public policy problems are ‘wicked’, being characterised by high complexity, many heterogeneous views and conflicts among various stakeholders. Therefore citizens interested to participate in such debates in order to be sufficiently informed should study large amounts of relevant material, such as reports, laws, committees’ minutes, etc., which are in legalistic or in other specialist languages, or very often their substance is hidden in political rhetoric, putting barriers to a meaningful participation. In this paper we present the results of the research we have conducted for addressing this problem through the use of ‘Computer Supported Argument Visualization’ (CSAV) methods for supporting and enhancing e-participation in the legislation formation process. This approach has been implemented in a pilot e-participation project and then evaluated using both quantitative and qualitative methods based on the ‘Technology Acceptance Model’ (TAM), with positive results. Based on the conclusions of this evaluation an enrichment of the IBIS framework has been developed for improving the visualization of legal documents.

    Sorption enhanced steam methane reforming (SE-SMR) process offers high potential for producing H{sub 2} in fuel cell applications compared to conventional catalytic steam methane reforming (SMR) process. The reactor temperature can significantly affect the performance of the SE-SMR reaction and simultaneous adsorption behavior of CO{sub 2}. Determination of an optimal temperature policy in SE-SMR reactor is therefore an important optimization issue. Multi-stage operation is a possible way to implement optimum temperature policies. In the present work, simulation study has been carried out for multi-stage operation using a mathematical model incorporating basic mechanisms operating in a fixed bed reactor with nonlinear reaction kinetic features of an SE-SMR process. Three cases were considered for implementing the multi-stage concept and the results show that increase in temperature based on a policy leads to considerable improvement in the process performance.

    This document describes the early stage of the reconstruction chain that was developed for the ArgoNeuT and MicroBooNE experiments at Fermilab. These experiments study accelerator neutrino interactions that occur in a Liquid Argon Time Projection Chamber. Reconstructing the properties of particles produced in these interactions requires knowledge of the micro-physics processes that affect the creation and transport of ionization electrons to the readout system. A wire signal deconvolution technique was developed to convert wire signals to a standard form for hit reconstruction, to remove artifacts in the electronics chain and to remove coherent noise.

    2011-12-01

    Full Text Available U.S. popular culture was considered initially by American political establishment as a mean of entertainment rather than an instrument of foreign policy. Before the Cold War American politicians never seriously thought of creating a cultural institution in the federal government. The paradox is that country where cultural export became later so large-scaled and caused a lot of controversy worldwide, originally demonstrated almost no interest in organized foreign cultural policy making. In the late 1930's and especially after World War II American political elite discovered and confirmed its view of culture as an effective tool of foreign policy, particularly at the ideological level (meanwhile the Soviet Union was leading in that confrontation for a long time - up to Gorbachev`s perestroika - outpacing the USA in production of soft power. Ideological dimension has always been and still remains an integral part of the U.S. foreign cultural policy.

  11. Processes of hypernuclei formation in relativistic ion collisions

    Directory of Open Access Journals (Sweden)

    Botvina Alexander

    2018-01-01

    Full Text Available The study of hypernuclei in relativistic ion collisions open new opportunities for nuclear and particle physics. The main processes leading to the production of hypernuclei in these reactions are the disintegration of large excited hyper-residues (target- and projectile-like, and the coalescence of hyperons with other baryons into light clusters. We use the transport, coalescence and statistical models to describe the whole reaction, and demonstrate the effectiveness of this approach: These reactions lead to the abundant production of multi-strange nuclei and new hypernuclear states. A broad distribution of predicted hypernuclei in masses and isospin allows for investigating properties of exotic hypernuclei, as well as the hypermatter both at high and low temperatures. There is a saturation of the hypernuclei production at high energies, therefore, the optimal way to pursue this experimental research is to use the accelerator facilities of intermediate energies, like FAIR (Darmstadt and NICA (Dubna.

    The specification discloses a spent seed recovery and regeneration process for an MHD power plant employing an alkali metal salt seed material such as potassium salt wherein the spent potassium seed in the form of potassium sulfate is collected from the flue gas and reacted with calcium hydroxide and carbon monoxide in an aqueous solution to cause the formation of calcium sulfate and potassium formate. The pH of the solution is adjusted to suppress formation of formic acid and to promote precipitation of any dissolved calcium salts. The solution containing potassium formate is then employed to provide the potassium salt in the form of potassium formate or, optionally, by heating the potassium formate under oxidizing conditions to convert the potassium formate to potassium carbonate. 5 figures.

  13. An experimental study on atomizing formation process of diesel spray

    In this study, the experiment has, been conducted to investigate the spray characteristics under the parameter of an ambient pressure with a single hole nozzle having aspect ratio(L/D) of 5 and diameter of 0.45mm. Under the condition of the injection pressure of 14Mpa, the initial disintegrating process of a diesel spray is investigated and analysized according to change of the ambient pressures, 0.1, 1, 2 and 3Mpa. The double flash method has been employed to visualize the process of the diesel sprays. The results obtained in this study are as follows: 1) After spray starts, the spray is shown as non-disturbance liquid column within about 1∼2mm from the nozzle tip, whose diameter is similar to that of a nozzle. For the same injection pressure, the increase of the ambient pressure makes the length of the non-disturbance liquid column become short. 2) Due to the surface wave, ligaments of the shape thread appear at the boundary of liquid column right after spray. The more developed wave together the progress of spray transforms ligaments into droplets that have generally the uniformed size. 3) In case spraying into chambers having different ambient pressures, 1, 2, and 3Mpa, the spray tip velocities reach up to 1.5, 1.2, and 0.6ms, respectively, and decrease with lapse of time. The spray angle keeps increasing for 0.6, 1.2, and 1.4ms after spray under the various ambient pressures, 3, 2, and 1Mpa, respectively, and begins to decrease and maintains the constant value. Therefore, the transition points appear near the point where the velocity decreases and the spray angle increases, simultaneously. The higher ambient pressure leads to fast appearance of transition under the same spray pressure. 4) The disintegrating mechanism of the liquid spray is two combined effects: a) friction forces between the surface waves generated at the surface of the liquid column and the ambient gas, b) the collisions of liquid droplets and ligaments by spray were overtaking

  14. National medicines policies – a review of the evolution and development processes

    Science.gov (United States)

    2013-01-01

    Objectives Continuous provision of appropriate medicines of assured quality, in adequate quantities, and at reasonable prices is a concern for all national governments. A national medicines policy (NMP) developed in a collaborative fashion identifies strategies needed to meet these objectives and provides a comprehensive framework to develop all components of a national pharmaceutical sector. To meet the health needs of the population, there is a general need for medicine policies based on universal principles, but nevertheless adapted to the national situation. This review aims to provide a quantitative and qualitative (describing the historical development) study of the development process and evolution of NMPs. Methods The number of NMPs and their current status has been obtained from the results of the assessment of WHO Level I indicators. The policy formulation process is examined in more detail with case studies from four countries: Sri Lanka, Australia, former Yugoslav Republic of Macedonia and South Africa. Results The number of NMPs worldwide has increased in the last 25 years with the highest proportional increase in the last 5–10 years in high-income countries. Higher income countries seem to have more NMP implementation plans available and have updated their NMP more recently. The four case studies show that the development of a NMP is a complex process that is country specific. In addition, it demonstrates that an appropriate political window is needed for the policy to be passed (for South Africa and the FYR Macedonia, a major political event acted as a trigger for initiating the policy development). Policy-making does not stop with the official adoption of a policy but should create mechanisms for implementation and monitoring. The NMPs of the FYR Macedonia and Australia provide indicators for monitoring. Conclusions To date, not all countries have a NMP since political pressure by national experts or non-governmental organizations is generally

    Recent years have seen a rise in new and innovative policies to reduce alcohol consumption and related harm in England, which can be implemented by local, as opposed to national, policy-makers. The aim of this paper is to explore the processes that underpin the adoption of these alcohol policies within local authorities. In particular, it aims to assess whether the concept of policy transfer (i.e. a process through which knowledge about policies in one place is used in the development of policies in another time or place) provides a useful model for understanding local alcohol policy-making. Qualitative data generated through in-depth interviews and focus groups from five case study sites across England were used to explore stakeholder experiences of alcohol policy transfer between local authorities. The purposive sample of policy actors included representatives from the police, trading standards, public health, licensing, and commissioning. Thematic analysis was used inductively to identify key features in the data. Themes from the policy transfer literature identified in the data were: policy copying, emulating, hybridization, and inspiration. Participants described a multitude of ways in which learning was shared between places, ranging from formal academic evaluation to opportunistic conversations in informal settings. Participants also described facilitators and constraints to policy transfer, such as the historical policy context and the local cultural, economic, and bureaucratic context, which influenced whether or not a policy that was perceived to work in one place might be transferred successfully to another context. Theories of policy transfer provide a promising framework for characterising processes of local alcohol policy-making in England, extending beyond debates regarding evidence-informed policy to account for a much wider range of considerations. Applying a policy transfer lens enables us to move beyond simple (but still important) questions of

    Full Text Available Abstract Background The interface between research and policymaking in low-income countries is highly complex. The ability of health systems research to influence policy processes in such settings face numerous challenges. Successful analysis of the research-policy interface in these settings requires understanding of contextual factors as well as key influences on the interface. Future Health Systems (FHS: Innovations for Equity is a consortium conducting research in six countries in Asia and Africa. One of the three cross-country research themes of the consortium is analysis of the relationship between research (evidence and policy making, especially their impact on the poor; insights gained in the initial conceptual phase of FHS activities can inform the global knowledge pool on this subject. Discussion This paper provides a review of the research-policy interface in low-income countries and proposes a conceptual framework, followed by directions for empirical approaches. First, four developmental perspectives are considered: social institutional factors; virtual versus grassroots realities; science-society relationships; and construction of social arrangements. Building on these developmental perspectives three research-policy interface entry points are identified: 1. Recognizing policy as complex processes; 2. Engaging key stakeholders: decision-makers, providers, scientists, and communities; and 3. Enhancing accountability. A conceptual framework with three entry points to the research-policy interface – policy processes; stakeholder interests, values, and power; and accountability – within a context provided by four developmental perspectives is proposed. Potential empirical approaches to the research-policy interface are then reviewed. Finally, the value of such innovative empirical analysis is considered. Conclusion The purpose of this paper is to provide the background, conceptual framework, and key research directions for

    The Vital Issues Process, developed by the Sandia National Laboratories Strategic Technologies Department, was utilized by the Health Care Task Force Advisory Group to apply structure to their policy deliberations. By convening three expert panels, an overarching goal for the New Mexico health care system, seven desired outcomes, nine policy options, and 17 action items were developed for the New Mexico health care system. Three broadly stated evaluation criteria were articulated and used to produce relative rankings of the desired outcomes and policy options for preventive care and information systems. Reports summarizing the policy deliberations were submitted for consideration by the Health Care Task Force, a Joint Interim Committee of the New Mexico Legislature, charged with facilitating the development and implementation of a comprehensive health care delivery system for New Mexico. The Task Force reported its findings and recommendations to the Second Session of the 41st New Mexico State Legislature in January 1994.

    Industrial flow lines are composed of unit processes operating on a fast time scale and performance measurements known as operational indices measured at a slower time scale. This paper presents a model-free optimal solution to a class of two time-scale industrial processes using off-policy reinforcement learning (RL). First, the lower-layer unit process control loop with a fast sampling period and the upper-layer operational index dynamics at a slow time scale are modeled. Second, a general optimal operational control problem is formulated to optimally prescribe the set-points for the unit industrial process. Then, a zero-sum game off-policy RL algorithm is developed to find the optimal set-points by using data measured in real-time. Finally, a simulation experiment is employed for an industrial flotation process to show the effectiveness of the proposed method.

  7. Water Transfer Characteristics during Methane Hydrate Formation Processes in Layered Media

    Full Text Available Gas hydrate formation processes in porous media are always accompanied by water transfer. To study the transfer characteristics comprehensively, two kinds of layered media consisting of coarse sand and loess were used to form methane hydrate in them. An apparatus with three PF-meter sensors detecting water content and temperature changes in media during the formation processes was applied to study the water transfer characteristics. It was experimentally observed that the hydrate formation configurations in different layered media were similar; however, the water transfer characteristics and water conversion ratios were different.

    Keratin intermediate filament networks are part of the cytoskeleton in epithelial cells. They were found to regulate viscoelastic properties and motility of cancer cells. Due to unique biochemical properties of keratin polymers, the knowledge of the mechanisms controlling keratin network formation is incomplete. A combination of deterministic and stochastic modeling techniques can be a valuable source of information since they can describe known mechanisms of network evolution while reflecting the uncertainty with respect to a variety of molecular events. We applied the concept of piecewise-deterministic Markov processes to the modeling of keratin network formation with high spatiotemporal resolution. The deterministic component describes the diffusion-driven evolution of a pool of soluble keratin filament precursors fueling various network formation processes. Instants of network formation events are determined by a stochastic point process on the time axis. A probability distribution controlled by model parameters exercises control over the frequency of different mechanisms of network formation to be triggered. Locations of the network formation events are assigned dependent on the spatial distribution of the soluble pool of filament precursors. Based on this modeling approach, simulation studies revealed that the architecture of keratin networks mostly depends on the balance between filament elongation and branching processes. The spatial distribution of network mesh size, which strongly influences the mechanical characteristics of filament networks, is modulated by lateral annealing processes. This mechanism which is a specific feature of intermediate filament networks appears to be a major and fast regulator of cell mechanics.

    Baum, Fran; Friel, Sharon

    2017-12-21

    The development and implementation of multisectoral policy to improve health and reduce health inequities has been slow and uneven. Evidence is largely focused on the facts of health inequities rather than understanding the political and policy processes. This 5-year funded programme of research investigates how these processes could function more effectively to improve equitable population health. The programme of work is organised in four work packages using four themes (macroeconomics and infrastructure, land use and urban environments, health systems and racism) related to the structural drivers shaping the distribution of power, money and resources and daily living conditions. Policy case studies will use publicly available documents (policy documents, published evaluations, media coverage) and interviews with informants (policy-makers, former politicians, civil society, private sector) (~25 per case). NVIVO software will be used to analyse the documents to see how 'social and health equity' is included and conceptualised. The interview data will include qualitative descriptive and theory-driven critical discourse analysis. Our quantitative methodological work assessing the impact of public policy on health equity is experimental that is in its infancy but promises to provide the type of evidence demanded by policy-makers. Our programme is recognising the inherently political nature of the uptake, formulation and implementation of policy. The early stages of our work indicate its feasibility. Our work is aided by a Critical Policy Reference Group. Multiple ethics approvals have been obtained with the foundation approval from the Social and Behavioural Ethics Committee, Flinders University (Project No: 6786).The theoretical, methodological and policy engagement processes established will provide improved evidence for policy-makers who wish to reduce health inequities and inform a new generation of policy savvy knowledge on social determinants. © Article author

  20. On applications of excess level processes to (N,D-policy bulk queueing systems

    Directory of Open Access Journals (Sweden)

    Jewgeni H. Dshalalow

    1996-01-01

    Full Text Available The paper deals with queueing systems in which N- and D-policies are combined into one. This means that an idle or vacationing server will resume his service if the queueing or workload process crosses some specified fixed level N or D, respectively. For the proposed (N,D-policy we study the queueing processes in models with and without server vacations, with compound Poisson input, and with generally distributed service and vacation periods. The analysis of the models is essentially based on fluctuation techniques for two-dimensional marked counting processes newly developed by the author. The results enable us to arrive at stationary distributions for the embedded and continuous time parameter queueing processes in closed analytic forms, enhancing the well-known Kendall formulas and their modifications.

    Full Text Available Abstract Background Following the recognition that morbidity and mortality due to malaria had dramatically increased in the last three decades, in 2002 the government of Zambia reviewed its efforts to prevent and treat malaria. Convincing evidence of the failing efficacy of chloroquine resulted in the initiation of a process that eventually led to the development and implementation of a new national drug policy based on artemisinin-based combination therapy (ACT. Methods All published and unpublished documented evidence dealing with the antimalarial drug policy change was reviewed. These data were supplemented by the authors' observations of the policy change process. The information has been structured to capture the timing of events, the challenges encountered, and the resolutions reached in order to achieve implementation of the new treatment policy. Results A decision was made to change national drug policy to artemether-lumefantrine (AL in the first quarter of 2002, with a formal announcement made in October 2002. During this period, efforts were undertaken to identify funding for the procurement of AL and to develop new malaria treatment guidelines, training materials, and plans for implementation of the policy. In order to avoid a delay in implementation, the policy change decision required a formal adoption within existing legislation. Starting with donated drug, a phased deployment of AL began in January 2003 with initial use in seven districts followed by scaling up to 28 districts in the second half of 2003 and then to all 72 districts countrywide in early 2004. Conclusion Drug policy changes are not without difficulties and demand a sustained international financing strategy for them to succeed. The Zambian experience demonstrates the need for a harmonized national consensus among many stakeholders and a political commitment to ensure that new policies are translated into practice quickly. To guarantee effective policies requires

  2. Influence in the Policy Making Process: the Rise of Economics at the Expense of Geology

    Science.gov (United States)

    McCurdy, K. M.

    2007-12-01

    Scientific influence in resource policy making reached a zenith in the early 1970s during the legislative monopoly in the United States Congress that produced command and control regulatory protection policies. This congressional consensus began in 1879 with legislation producing the U.S. Geological Survey. Other scientific agencies followed. The Congresses of the first half of the 20th century merely strengthened the influence of science in policy outcomes that was present in the earliest congressional debates. What then happened at the turn of the 21st century when representatives in the administration frequently dismissed sound science in their policy deliberations? Policy monopolies arise from agreement in principle, and alternately decline as rival ideas gain hold in policy space. The science policy monopoly began to face competition from economics when cost benefit analysis was introduced into political parlance in 1936, again in the 1950s as a successful blocking tactic by the minority in opposition to western dams, and in 1961 when systems analysis was introduced to the Department of Defense under Robert McNamara. As businessmen replaced farmers as the modal profession of legislators, the language of politics increasingly contained economic terms and concepts. A ternary diagram and a budget simplex have the same shape, but have different theoretical meanings and imply different processes. Policy consensus is not dissimilar to a mineral phase diagram, with boundary conditions marked by election magnitudes and majority parties. The 1980 elections brought economic principles into all aspects of government decision-making, with a particular long-term interest in reducing the size and scope of government. Since then the shift in policy jargon from science to economics has been incremental. With the 1994 Republican legislative majority, scientists, their programs, and the funds required to maintain data collection projects became targets. The Conservative

    Canada is faced with the important decision of whether it should ratify the Kyoto Protocol. A reference for stakeholders and non-expert interested parties, this document is a guide into the Canadian Climate Change Policy Process. An understanding of climate science is required for climate policy, as is a knowledge of policy options available to overcome the challenges posed by climate change. The situation is further complicated by international and federal-provincial negotiations over the measures that should be implemented, if any. Climate policy affects all aspects of our lives, especially how we produce and use energy. An overview of climate science is provided in the first section, and the relationship between climate and rising temperatures due to greenhouse gas emissions is established. The sources of greenhouse gases in Canada are identified, with a closer look at the current trends. The Kyoto Protocol, if ratified, calls for Canada to reduce its emissions of greenhouse gases to six per cent below 1990 levels. It is noted that to date, Canada's emissions have risen 19.7 per cent above 1990 levels. The process underlying the international negotiations associated with the Kyoto Protocol, and especially Canada's role in it, are discussed. Flexibility mechanisms are strongly supported by Canada, such as credits for sinks, international carbon trading and credits for Clean Energy Exports. By approving such measures, the integrity of the Protocol would be considerably weakened. The domestic policy-making environment is examined, presenting key federal, provincial business and environmental players. In addition, the policy process in Canada is described, as well as the decisions made up to September 2002. Bibliographic and contact information is added in the last section of the document. 89 refs., 7 tabs., 7 figs

  4. Formation of Globular Clusters with Internal Abundance Spreads in r -Process Elements: Strong Evidence for Prolonged Star Formation

    Several globular clusters (GCs) in the Galaxy are observed to show internal abundance spreads in r -process elements (e.g., Eu). We propose a new scenario that explains the origin of these GCs (e.g., M5 and M15). In this scenario, stars with no/little abundance variations first form from a massive molecular cloud (MC). After all of the remaining gas of the MC is expelled by numerous supernovae, gas ejected from asymptotic giant branch stars can be accumulated in the central region of the GC to form a high-density intracluster medium (ICM). Merging of neutron stars then occurs to eject r -process elements, which can be efficiently trapped in and subsequently mixed with the ICM. New stars formed from the ICM can have r -process abundances that are quite different from those of earlier generations of stars within the GC. This scenario can explain both (i) why r -process elements can be trapped within GCs and (ii) why GCs with internal abundance spreads in r -process elements do not show [Fe/H] spreads. Our model shows (i) that a large fraction of Eu-rich stars can be seen in Na-enhanced stellar populations of GCs, as observed in M15, and (ii) why most of the Galactic GCs do not exhibit such internal abundance spreads. Our model demonstrates that the observed internal spreads of r -process elements in GCs provide strong evidence for prolonged star formation (∼10{sup 8} yr).

    This paper examines the processing steps of extracting palm oil from fresh fruit bunches in a way that may impact on the formation of chloropropandiol fatty esters (3-MCPD esters), particularly during refining. Diacylglycerols (DAGs) do not appear to be a critical factor when crude palm oils are extracted from various qualities of fruit bunches. Highly hydrolysed oils, in spite of the high free fatty acid (FFA) contents, did not show exceptionally high DAGs, and the oils did not display a higher formation of 3-MCPD esters upon heat treatment. However, acidity measured in terms of pH appears to have a strong impact on 3-MCPD ester formation in the crude oil when heated at high temperatures. The differences in the extraction process of crude palm oil from current commercial processes and that from a modified experimental process showed clearly the effect of acidity of the oil on the formation of 3-MCPD esters. This paper concludes that the washing or dilution step in palm oil mills removes the acidity of the vegetative materials and that a well-optimised dilution/washing step in the extraction process will play an important role in reducing formation of 3-MCPD esters in crude palm oil upon further heat processing.

    Full Text Available We study the policy iteration algorithm (PIA for continuous-time jump Markov decision processes in general state and action spaces. The corresponding transition rates are allowed to be unbounded, and the reward rates may have neither upper nor lower bounds. The criterion that we are concerned with is expected average reward. We propose a set of conditions under which we first establish the average reward optimality equation and present the PIA. Then under two slightly different sets of conditions we show that the PIA yields the optimal (maximum reward, an average optimal stationary policy, and a solution to the average reward optimality equation.

    Prompted by the need to achieve progress in health outcomes, payment for performance (P4P) schemes are becoming popular policy options in the health systems in many low income countries. This paper describes the policy process behind the introduction of a payment for performance scheme in the health sector of Tanzania illuminating in particular the interests of and roles played by the Government of Norway, the Government of Tanzania and the other development partners. The study employed a qualitative research design using in-depth interviews (IDIs), observations and document reviews. Thirteen IDIs with key-informants representing the views of ten donor agencies and government departments influential in the process of introducing the P4P scheme in Tanzania were conducted in Dar es Salaam, Tanzania and Oslo, Norway. Data was collected on the main trends and thematic priorities in development aid policy, countries and actors perceived to be proponents and opponents to the P4P scheme, and P4P agenda setting in Tanzania. The initial introduction of P4P in the health sector of Tanzania was controversial. The actors involved including the bilateral donors in the Health Basket Fund, the World Bank, the Tanzanian Government and high level politicians outside the Health Basket Fund fought for their values and interests and formed alliances that shifted in the course of the process. The process was characterized by high political pressure, conflicts, changing alliances, and, as it evolved, consensus building. The P4P policy process was highly political with external actors playing a significant role in influencing the agenda in Tanzania, leaving less space for the Government of Tanzania to provide leadership in the process. Norway in particular, took a leading role in setting the agenda. The process of introducing P4P became long and frustrating causing mistrust among partners in the Health Basket Fund.

    Full Text Available Counteraction to Islamic extremism is the major problem in the modern world. The government of the Russian Empire solved this problem through purposeful education of confessional tolerance of Muslims in 1773–1917. Authors compare understanding of tolerance in Russia and in Western Siberia in 1773-1917, emphasizing that in the Tyumen region society understood this term the same as now. On the basis of earlier unknown archival documents of the Central historical archive of the Republic of Bashkortostan authors consider a state policy on formation of a certain option of Islam which provides religious tolerance in Russia. In article the main attention is paid to Western Siberia as exactly there the confessional state policy made the greatest success. The main directions of a state policy were: to unify Muslim culture according to orthodox samples; to keep the Siberian option of Islam; to create obstacles for distribution of standard Islam; to develop the state measures which would show respect for Muslims and care of them. Authors consider ways of deformation of Muslim culture in Western Siberia: change of architectural forms of mosques and necropolises, deformation of cult objects (existence of a religious sculpture, selection of literature in Muslim libraries, the facilitated conditions for examinations on the mullah's rank, appointment to positions of muftis without spiritual education in the Orenburg Mohammedan spiritual meeting, creation of obstacles for commission of a hajj to Mecca for mullahs.

  12. "Formative ""Use"" of Assessment Information: It's a Process, so Let's Say What We Mean"

    Directory of Open Access Journals (Sweden)

    Robert Good

    2011-02-01

    Full Text Available The term formative assessment is often used to describe a type of assessment. The purpose of this paper is to challenge the use of this phrase given that formative assessment as a noun phrase ignores the well-established understanding that it is a process more than an object. A model that combines content, context, and strategies is presented as one way to view the process nature of assessing formatively. The alternate phrase formative use of assessment information is suggested as a more appropriate way to describe how content, context, and strategies can be used together in order to close the gap between where a student is performing currently and the intended learning goal.

    This invention relates to a method of storing gas using gas hydrates comprising forming gas hydrates in the presence of a water-surfactant solution that comprises water and surfactant. The addition of minor amounts of surfactant increases the gas hydrate formation rate, increases packing density of the solid hydrate mass and simplifies the formation-storage-decomposition process of gas hydrates. The minor amounts of surfactant also enhance the potential of gas hydrates for industrial storage applications.

    . The main problems, which arise in the process of deposit-taking banks’ activities, including lack of resource support for active operations to ensure the country’s economic development and ways to improve deposit policy. Conclusions. The basis for the formation of the deposit portfolio structure is the implementation of effective deposit policy, which is extremely important for banking institutions at the present stage of development, as it promotes the improvement of banking activity in the process of attracting funds as an investment resource. The savings of Ukraine’s population have significant potential for further investment. That is why there is a need to build the infrastructure of the financial sector, improve legislation, and increase the overall financial literacy of the population, which should become a prerequisite for investment activity in Ukraine. In today’s conditions of development of the national economy, the question of improving the financial mechanism of converting savings into investment resources is very important, as the investment potential, which is concentrated in the savings of the population, is significant for expanding the boundaries of investment activity in the country.

    Herrmann, Susan Strange

    N-nitrosamines (NA) occur in sodium nitrite (nitrite) preserved meat products as bacon, sausages, ham and several types of luncheon meats. Several of these NA are carcinogenic and high intake of processed meat products has been associated with increased risk of cancer and other adverse health...... effects in some epidemiologic studies. Exposure to NA via meat products may be the underlying reason for this association. The levels of NA in processed meat products ought therefore to be as low as possible. There is a large amount of literature on the occurrence, formation and mitigation of NA in meat...... is it to identify strategies for the prevention of NA formation in general and not only for a few NA. The aim of the present thesis was therefore to study the role of ingoing amount of nitrite, factors relevant for industrial processing of meat, fat content and the effect of heat treatment on the formation of VNA...

In this study, the cocrystal of piracetam and 3-hydroxybenzoic acid under grinding condition has been characterized by Raman and terahertz spectroscopical techniques. The major vibrational modes of individual starting components and cocrystal are obtained and assigned. Spectral results show that the vibrational modes of the cocrystal are different from those of the corresponding parent materials. The dynamic process of such pharmaceutical cocrystal formation has also been monitored directly with Raman and THz spectra. The formation rate is pretty fast in first several 20 min grinding time, and then it becomes slow. After ∼35 min, such process has been almost completed. These results offer us the unique means and benchmark for characterizing the cocrystal conformation from molecule-level and also provide us rich information about the reaction dynamic during cocrystal formation process in pharmaceutical fields.

  1. Using Structured e-Forum to Support the Legislation Formation Process

    Science.gov (United States)

    Xenakis, Alexandros; Loukis, Euripides

    Many public policy problems are 'wicked', being characterised by high complexity, many heterogeneous views and conflicts among various stakeholders, and also lack of mathematically 'optimal' solutions and predefined algorithms for calculating them. The best approach for addressing such problems is through consultation and argumentation among stakeholders. The e-participation research has investigated and suggested several ICT tools for this purpose, such as e-forum, e-petition and e-community tools. This paper investigates the use of an advanced ICT tool, the structured e-forum, for addressing such wicked problems associated with the legislation formation. For this purpose we designed, implemented and evaluated two pilot e-consultations on legislation under formation in the Parliaments of Austria and Greece using a structured e-forum tool based on the Issue Based Information Systems (IBIS) framework. The conclusions drawn reveal the advantages offered by the structured e-forum, but also its difficulties as well.

    Full Text Available The aim of the publication is to determine the interrelation of the formation of subjective qualities and norms process of adaptation of young employees at the enterprise.Methods. The research methodology involves a comprehensive combination of the theoretical analysis and the results of applied research at the enterprises of the Sverdlovsk region. The dialectical method and comparative analysis are used.Results and theoretical novelty. The questions of adaptation of young employees at the enterprise are considered. The concepts of «subjectivity» and «norms» in philosophy are analyzed. Subjectivity is presented as a personal basis of social activity of the young worker at the entity; regulations – as a method of adaptation of the personality, individual to that community in which it emerged to be. The characteristics of the youth working at the industrial enterprise are disclosed on the basis of socio-philosophical analysis; youth policy at the industrial enterprises is described; the formation of values and norms of young workers in the process of adapting the enterprise is observed. The personal subjectivity as the basis of social activity of the young worker in the enterprise is demonstrated. It is shown that relevance of subject qualities forming and regulations at youth is caused not only by the need of development of the identity of young workers, but also by economic safety of industrial enterprises wellbeing where their working career begins.Practical significance consists in the social-philosophical substantiation of interrelation of formation of subjective qualities and norms in the process of adaptation of young employees in the company, of the main provisions for the development of programs of adaptation of young employees at the enterprise; in providing the teaching social and humanitarian disciplines for bachelors and masters majoring in «Organization of Work with Youth».

    In this context, a typical lead-acid battery producing process is introduced. Based on the formation process, an efficiency management method is proposed. An optimization model with the objective to minimize the formation electricity cost in a single period is established. This optimization model considers several related constraints, together with two influencing factors including the transformation efficiency of IGBT charge-and-discharge machine and the time-of-use price. An example simulation is shown using PSO algorithm to solve this mathematic model, and the proposed optimization strategy is proved to be effective and learnable for energy-saving and efficiency optimization in battery producing industries.

    Recommendations from the World Health Organization (WHO) are crucial to inform developing country decisions to use, or not, a new intervention. This article analysed the WHO policy development process to predict its course for a malaria vaccine. The decision-making processes for one malaria intervention and four vaccines were classified through (1) consultations with staff and expert advisors to WHO's Global Malaria Programme (GMP) and Immunization, Vaccines and Biologicals Department (IVB); (2) analysis of the procedures and recommendations of the major policy-making bodies of these groups; (3) interviews with staff of partnerships working toward new vaccine availability; and (4) review and analyses of evidence informing key policy decisions. WHO policy formulation related to use of intermittent preventive treatment in infancy (IPTi) and the following vaccine interventions: Haemophilus influenzae type b conjugate vaccine (Hib), pneumococcal conjugate vaccine (PCV), rotavirus vaccine (RV), and human papillomavirus vaccine (HPV), five interventions which had relatively recently been through systematic WHO policy development processes as currently constituted, was analysed. Required information was categorized in three areas defined by a recent WHO publication on development of guidelines: safety and efficacy in relevant populations, implications for costs and population health, and localization of data to specific epidemiological situations. Data needs for a malaria vaccine include safety; the demonstration of efficacy in a range of epidemiological settings in the context of other malaria prevention interventions; and information on potential rebound in which disease increases subsequent to the intervention. In addition, a malaria vaccine would require attention to additional factors, such as costs and cost-effectiveness, supply and demand, impact of use on other interventions, and distribution issues. Although policy issues may be more complex for future vaccines

    Full Text Available This article applies the perspective of historical institutionalism to the empirical analysis of the motors and characteristics of the institutionalisation process of the European Union’s anti-terrorist policies. Based on a theoretical model developed by Stone Sweet, Sandholtz and Fligstein, this contribution critically analyses the impact of external crises in the form of a series of terrorist attacks on the emergence of antiterrorism as an sphere of European governance. The article also examines political developments and key institutions, studies the role of policy entrepreneurs during this period and compares the importance of “revolutionary” and “evolutionist” perspectives to our understanding of the process of institutional change in this field.

  7. Spatial misfits in a multi-level renewable energy policy implementation process on the Small Island State of Malta

    2010-01-01

    One of the priorities of energy policies of the European Union (EU) is to generate 20% of EU's total energy consumption from renewable energy (RE) sources by 2020. The EU policy framework mainly emphasizes economical and technical aspects of RE sources, and promotes large scale projects. However the local implementation of RE EU policies can lead to spatial misfits if the policy implementation neglects the peculiarities of the place. It is important to understand the misfits and relationship between the EU RE policies and the local implementation process, as misfits can affect the policy implementation process and subsequently policy outcomes can be different from those intended, leading to inapt or inapplicable measures. This article presents findings of a qualitative in-depth study of Malta's RE policy implementation. The paper shows that planning of central large-scale RE projects in Malta provokes land and marine use conflicts and can cause difficulties in implementation. The concerned key actors implement the policies according to their motivation, perception, and capacity, and the context in which they are embedded. Hence, both the EU RE policy framework and the national interaction process influence the implementation process, which can lead to spatial mismatches.

    2012-09-01

    Full Text Available This article focuses on how sub-national entities’ gradual participation in Brazilian foreign policy has come about, with reference to a decentralised scenario of the decision-making process in Itamaraty, where the ministries and presidential organs have a voice on many strategic themes, mainly concerning development. The article examines the insertion of sub-national entities into the decision-making process in the Southern Common Market (Mercosur, and concludes that in spite of the incipient participation, relevant contributions to the process of regional integration have arisen. Regarding the hypothesis that the participation of the federative entities in the decision-making process generates local and regional development, we argue that this is an alternative to increasing state efficiency. In conclusion, and despite the incipient institutionalisation that does not guarantee their vote in the decision-making process, at least their voice is heard.

    All processes are studied visible during the development of the magnetic field, sunspots and chromospheric structures in the usual active region of August 1974. The connection of the active region with the dynamics of the background field is discussed. The formation of a ''centre of magnetic activity'' is demonstrated on magnetic charts as well as in photospheric and chromospheric details. The regularities in the active region's magnetic field topology and dynamics, and their relations to the sunspot group development and formation of individual sunspots are shown. The process is described of formation of a penumbra as a slow, continuous reorganization of granular field areas around the main spot nucleus in strong dependence on the field topology. It may proceed successively around the umbra surrounded by the opposite polarity in the course of several hours, stopping or possibly reversing before it continues its growth. Again it is very difficult to explain the observed field behaviour on a model of emerging flux tubes. (author)

    2018-01-01

    Background In 2009, the Benin government introduced a user fee exemption policy for caesarean sections. We analyse this policy with regard to how the existing ideas and institutions related to user fees influenced key steps of the policy cycle and draw lessons that could inform the policy dialogue for universal health coverage in the West African region. Methods Following the policy stages model, we analyse the agenda setting, policy formulation and legitimation phase, and assess the implementation fidelity and policy results. We adopted an embedded case study design, using quantitative and qualitative data collected with 13 tools at the national level and in seven hospitals implementing the policy. Results We found that the initial political goal of the policy was not to reduce maternal mortality but to eliminate the detention in hospitals of mothers and newborns who cannot pay the user fees by exempting a comprehensive package of maternal health services. We found that the policy development process suffered from inadequate uptake of evidence and that the policy content and process were not completely in harmony with political and public health goals. The initial policy intention clashed with the neoliberal orientation of the political system, the fee recovery principles institutionalised since the Bamako Initiative and the prevailing ideas in favour of user fees. The policymakers did not take these entrenched factors into account. The resulting tension contributed to a benefit package covering only caesarean sections and to the variable implementation and effectiveness of the policy. Conclusion The influence of organisational culture in the decision-making processes in the health sector is often ignored but must be considered in the design and implementation of any policy aimed at achieving universal health coverage in West African countries.

    Implementing evidence-based practices and policies for breastfeeding support in community clinics is a promising, but challenging, approach to reducing disparities in breastfeeding rates. This study aimed to apply a policy process research framework to increase knowledge of factors that facilitate adoption and implementation of breastfeeding policy changes. In 2013, Washington State piloted a process to encourage 8 clinics to adopt and implement steps to become breastfeeding friendly. Evaluation data were collected through interviews, project reports, training evaluations, and pre- and post-self-assessments of achievement of the steps. In 6 months, clinics increased the breastfeeding-friendly steps that they were implementing from a median (interquartile range) of 1.5 (0-3) to 6 (5-7). Improvements were most likely in the steps that required the fewest resources and administrative changes. Barriers to implementation included misperceptions about breastfeeding and breastfeeding support; lack of administrative "buy-in"; need for organizational changes to accommodate actions like monitoring breastfeeding rates and allowing providers training time; and the social-political climate of the clinic. Several factors, including actions taken by public health practitioners, enhanced the change process. These included fostering supportive relationships, targeting technical assistance, and providing resources for planning and training. This pilot project demonstrates that it is possible to make changes in breastfeeding support practices and policies in community clinics. Recommendations to enhance future work include framing and marketing breastfeeding support in ways that resonate with clinic decision makers and enhancing training, resources, and advocacy to build capacity for internal and external systems changes to support breastfeeding best practices. © The Author(s) 2015.

    Silica nanoparticles exhibiting hexagonal, cubic, and vesicular mesostructures have been prepared using aerosol assisted, self-assembled process. This process begins with homogennous aerosol droplets containing silica source, water, ethanol, and surfactant, in which surfactant concentration is far below the critical micelle concentration (cmc). Solvent evaporation enriches silica and surfactant inducing interfacial self-assembly confined to a spherical aerosol droplet and results in formation of completely solid, ordered spherical particles with stable hexagonal, cubic, or vesicular mesostructures.

    Full Text Available The formation of a methodological approach to evaluating management of the state of enterprise flow processes has been considered. Proceeding from the developed and presented in literary sources theoretical propositions on organization of management of enterprise flow processes, the hypothesis of the study is correlation of quantitative and qualitative evaluations of management effectiveness and formation of the integral index on their basis. The article presents stages of implementation of a methodological approach to evaluating the state of management of enterprise flow processes, which implies indicating the components, their characteristics and methods of research. The composition of indicators, on the basis of which it is possible to evaluate effectiveness of management of enterprise flow processes, has been determined. Grouping of such indicators based on the flow nature of enterprise processes has been performed. The grouping of indicators is justified by a pairwise determination of canonical correlations between the selected groups (the obtained high correlation coefficients confirmed the author’s systematization of indicators. It is shown that a specificity of the formation of a methodological approach to evaluating the state of management of enterprise flow processes requires expansion in the direction of aggregation of the results and determination of factors that influence effectiveness of flow processes management. The article carries out such aggregation using the factor analysis. Distribution of a set of objects into different classes according to the results of the cluster analysis has been presented. To obtain an integral estimation of effectiveness of flow processes management, the taxonomic index of a multidimensional object has been built. A peculiarity of the formed methodological approach to evaluating the state of management of enterprise flow processes is in the matrix correlation of integral indicators calculated on

    Highlights: Black-Right-Pointing-Pointer We observe lag-phase crystallization process in insulin. Black-Right-Pointing-Pointer The crystallization is a result of the formation of higher order oligomers. Black-Right-Pointing-Pointer The crystallization also changes the secondary structure of the protein. Black-Right-Pointing-Pointer The spectroscopic signature can be used for amyloid inhibitors assay. -- Abstract: Insulin, as other amyloid proteins, can form amyloid fibrils at certain conditions. The self-assembled aggregation process of insulin can result in a variety of conformations, starting from small oligomers, going through various types of protofibrils, and finishing with bundles of fibrils. One of the most common consensuses among the various self-assembly processes that are suggested in the literature is the formation of an early stage nucleus conformation. Here we present an additional insight for the self-assembly process of insulin. We show that at the early lag phase of the process (prior to fibril formation) the insulin monomers self-assemble into ordered nanostructures. The most notable feature of this early self-assembly process is the formation of nanocrystalline nucleus regions with a strongly bound electron-hole confinement, which also change the secondary structure of the protein. Each step in the self-assembly process is characterized by an optical spectroscopic signature, and possesses a narrow size distribution. By following the spectroscopic signature we can measure the potency of amyloid fibrils inhibitors already at the lag phase. We further demonstrate it by the use of epigallocatechin gallate, a known inhibitor for insulin fibrils. The findings can result in a spectroscopic-based application for the analysis of amyloid fibrils inhibitors.

    2013-10-01

    We investigated the processes involved in the construction of the Brazilian National Health Promotion Policy (PNPS) through the analysis of three documents produced by the Ministry of Health from 2002 to 2005 and the final text of the National Health Promotion Policy, approved in 2006. We interviewed five subjects who participated in drafting the PNPS, three of whom were Ministry of Health administrators, plus two researchers. The documents were explored with discourse analysis. The article contributes to the debate on the development of the PNPS. Health promotion showed various points of disagreement, which led to the delay in the document's final approval. International induction via funding proved to be a crucial element for defining the final wording of the PNPS, reestablishing the emphasis (subject to criticism) on lifestyle changes in its "Actions". The article highlights the negotiated consensus that led to the creation of the PNPS Management Committee, with participation by various sub-sectors, an innovative structure within the Ministry of Health.

The goal of this study was to investigate the peripheral action of oxytocin (OT) in the alveolar healing process in old female rats. Females Wistar rats (24-month-old) in permanent diestrus phase, received two ip (12h apart) injections of saline (NaCl 0.15M - control group) or OT (45μg/rat - treated group). Seven days later, the right maxillary incisor was extracted and analyses were performed up to 28 days of the alveolar healing process (35 days after saline or OT administration). Calcium and phosphorus plasma concentrations did not differ between the groups. The plasma biochemical bone formations markers, alkaline phosphatase (ALP) and osteocalcin were significantly higher in the treated group. Histomorphometric analyses confirmed bone formation as the treated group presented the highest mean value of post-extraction bone formation. Tartrate-resistant acid phosphatase (TRAP) was significantly reduced in the treated group indicating an anti-resorptive effect of OT. Immunohistochemistry reactions performed in order to identify the presence of osteocalcin and TRAP in the bone cells of the dental socket confirmed these outcomes. OT was found to promote bone formation and to inhibit bone resorption in old acyclic female rats during the alveolar healing process. Published by Elsevier Ltd.

    One approach to enhance curcumin (CUR) aqueous solubility is to use cyclodextrins (CDs) to form inclusion complexes where CUR is encapsulated as a guest molecule within the internal cavity of the water-soluble CD. Several methods have been reported for the complexation of CUR with CDs. Limited information, however, is available on the use of the autoclave process (AU) in complex formation. The aims of this work were therefore to (1) investigate and evaluate the AU cycle as a complex formation method to enhance CUR solubility; (2) compare the efficacy of the AU process with the freeze-drying (FD) and evaporation (EV) processes in complex formation; and (3) confirm CUR stability by characterizing CUR:CD complexes by NMR, Raman spectroscopy, DSC, and XRD. Significant differences were found in the saturation solubility of CUR from its complexes with CD when prepared by the three complexation methods. The AU yielded a complex with expected chemical and physical fingerprints for a CUR:CD inclusion complex that maintained the chemical integrity and stability of CUR and provided the highest solubility of CUR in water. Physical and chemical characterizations of the AU complexes confirmed the encapsulated of CUR inside the CD cavity and the transformation of the crystalline CUR:CD inclusion complex to an amorphous form. It was concluded that the autoclave process with its short processing time could be used as an alternate and efficient methods for drug:CD complexation. Copyright © 2017 Elsevier B.V.

    Phase formation in the alloys obtained during process of collective Ti and Fe oxides reduction by Al has been investigated. Thermodynamic computer simulation of the process (based on the system free energy minimizing principle) has indicated a range of possible reactions with various metallic compounds formation. Differential-thermal (DT), X-ray diffraction (XRD) methods and melting of reaction mixtures at 1773-1973 K have been carried out to confirm the thermodynamic predictions. The DT experiments showed that the process began after Al melting at 943 K and was accompanied by large exothermic effects. The intermetallic phases of alloys with various content of Ti, Fe and Al have been observed by the XRD analysis.

    Full Text Available Thermal spraying is a well-established surface modification technology which has been widely used in industrial applications. As the coating properties were mainly determined by the flattening nature of each splat, much attention has been increasingly paid to the study on the splat formation process of thermal sprayed particles. This paper is concerned with the development in the research of the splat formation process of the individual splat deposited by thermal spraying during the past few decades, including the experimental and numerical simulations up to today; some classical splashing models were also reviewed. As a simulation of the actual thermal spray process, the development of the flattening behavior of free falling droplet has been mentioned as well. On the basis of the current investigation, some recommendations for the future work have been advised.

    Clinical supervision should be a proactive and considered endeavor, not a reactive one. To that end, supervisors should choose supervision processes that are driven by theory, best available research, and clinical experience. These processes should be aimed at helping trainees develop as clinicians. We highlight 3 supervision processes we believe should be used at each supervision meeting: agenda setting, encouraging trainee problem-solving, and formative feedback. Although these are primarily cognitive-behavioral skills, they can be helpful in combination with other supervision models. We provide example dialogue from supervision exchanges, and discuss theoretical and research support for these processes. Using these processes not only encourages trainee development but also models for them how to use the same processes and approaches with clients. (c) 2015 APA, all rights reserved).

    Full Text Available Cultural phenomena and processes in the contemporary society, influenced by the social development models and by the fact that the constitutive elements of the culture have become the decisive factors of social change, are the determinants of the cultural policies. They are centered on the active process of cultural globalization that emphasizes besides the assimilation of the European principles, also the preservation of the cultural dialog without identity loss. Contemporary culture cannot be appreciated unless we know the main processes and phenomena that lately have generated impressive changes in the area of technology and means of communication. Due to these transformations we witness a change of the cultural paradigms, a mutation of values.

  4. FORMULATION OF NON-STEADY-STATE DUST FORMATION PROCESS IN ASTROPHYSICAL ENVIRONMENTS

    2013-01-01

    The non-steady-state formation of small clusters and the growth of grains accompanied by chemical reactions are formulated under the consideration that the collision of key gas species (key molecule) controls the kinetics of dust formation process. The formula allows us to evaluate the size distribution and condensation efficiency of dust formed in astrophysical environments. We apply the formulation to the formation of C and MgSiO 3 grains in the ejecta of supernovae, as an example, to investigate how the non-steady effect influences the formation process, condensation efficiency f con, ∞ , and average radius a ave, ∞ of newly formed grains in comparison with the results calculated with the steady-state nucleation rate. We show that the steady-state nucleation rate is a good approximation if the collision timescale of key molecule τ coll is much smaller than the timescale τ sat with which the supersaturation ratio increases; otherwise the effect of the non-steady state becomes remarkable, leading to a lower f con, ∞ and a larger a ave, ∞ . Examining the results of calculations, we reveal that the steady-state nucleation rate is applicable if the cooling gas satisfies Λ ≡ τ sat /τ coll ∼> 30 during the formation of dust, and find that f con, ∞ and a ave, ∞ are uniquely determined by Λ on at the onset time t on of dust formation. The approximation formulae for f con, ∞ and a ave, ∞ as a function of Λ on could be useful in estimating the mass and typical size of newly formed grains from observed or model-predicted physical properties not only in supernova ejecta but also in mass-loss winds from evolved stars

    Equity and social inclusion for vulnerable groups in policy development processes and resulting documents remain a challenge globally. Most often, the marginalization of vulnerable groups is overlooked in both the planning and practice of health service delivery. Such marginalization may occur because authorities deem the targeting of those who already have better access to healthcare a cheaper and easier way to achieve short-term health gains. The Government of Malawi wishes to achieve an equitable and inclusive HIV and AIDS Policy. The aim of this study is to assess the extent to which the Malawi Policy review process addressed regional and international health priorities of equity and social inclusion for vulnerable groups in the policy content and policy revision process. This research design comprised two phases. First, the content of the Malawi HIV and AIDS Policy was assessed using EquiFrame regarding its coverage of 21 Core Concepts of human rights and inclusion of 12 Vulnerable Groups. Second, the engagement of vulnerable groups in the policy process was assessed using the EquIPP matrix. For the latter, 10 interviews were conducted with a purposive sample of representatives of public sector, civil society organizations and development partners who participated in the policy revision process. Data was also collected from documented information of the policy processes. Our analyses indicated that the Malawi HIV and AIDS Policy had a relatively high coverage of Core Concepts of human rights and Vulnerable Groups; although with some notable omissions. The analyses also found that reasonable steps were taken to engage and promote participation of vulnerable groups in the planning, development, implementation, monitoring and evaluation processes of the HIV and AIDS Policy, although again, with some notable exceptions. This is the first study to use both EquiFrame and EquIPP as complimentary tools to assess the content and process of policy. While the findings

    In New Zealand, a public health programme on gambling policy development is part of a national gambling harm reduction and prevention strategy mandated by the Gambling Act 2003. Funded by the Ministry of Health, the programme directs workplace/organisational gambling policies, non-gambling fundraising policies, and local council policies on electronic gaming machines (EGMs). We carried out a process evaluation of this programme to identify practical information (e.g. advocacy approaches; challenges and ameliorating strategies) that can be used by programme planners and implementers to reinforce programme effectiveness and serve to guide similar policy-focused public health initiatives elsewhere. Evaluation criteria, based on the programme's official service specifications, guided our evaluation questions, analysis and reporting. To identify informative aspects of programme delivery, we thematically analysed over 100 six-monthly implementer progress reports (representing 3 years of programme delivery) and transcript of a focus group with public health staff. Identified output-related themes included purposeful awareness raising to build understanding about gambling harms and the need for harm-reduction policies and stakeholder relationship development. Outcome-related themes included enhanced community awareness about gambling harms, community involvement in policy development, some workplace/organisational policy development, and some influences on council EGM policies. Non-gambling fundraising policy development was not common. The programme offers an unprecedented gambling harm reduction approach. Although complex (due to its three distinct policy focus areas targeting different sectors) and challenging (due to the extensive time and resources needed to develop relationships and overcome counteractive views), the programme resulted in some policy development. Encouraging workplace/organisational policy development requires increased awareness of costs to

    Evidence-informed policies can produce social and economic impacts and equity and health benefits. Interaction between researchers in politics depends on the interests of social stakeholders and favorable political environments. This paper seeks to understand the meanings and researchers' perspectives of interaction processes between scientists and decision-makers that would influence the research impact on the health policy. This is a qualitative content analysis study conducted in 2014 to identify the core meanings and relationships between research and politics. The paper builds on the RAPID program approach of the Overseas Development Institute. Fourteen researchers who conducted maternal and neonatal morbidity and mortality studies sponsored by the Health Ministry were interviewed. Researchers focused on the production of knowledge, strengthening of research capacities and dissemination of results. On some occasions, researchers also participated in the definition of clinical care policies and performance of health services. They pointed to barriers to interact and produce an impact on politics due to tensions in the political, economic and social context, as well as to institutional and organizational changes in the health sector and to the academic evaluation system.

  14. Space Politics and Policy: An Evolutionary Perspective

    Science.gov (United States)

    Sadeh, Eligar

    2002-01-01

    This paper offers an evolutionary perspective of space policy. It is argued that (1) space policy is evolutionary in that it has responded to dramatic political events, such as the launching of Sputnik and the Cold War, and has undergone dynamic and evolutionary policy changes over the course of the past fifty years of the space-age; and that (2) space policy is an integral part of and interacts with public policy processes in the United States and abroad. To this end, the paper analyzes space policy at several levels of analysis. This includes: (1) historical context, political actors and institutions, political processes, and policy outcomes; (2) the symbiotic relationships between policy and space technology; and (3) future space policy trends and developments likely to occur in the 21st century. A "Space Politics and Policy Framework" is developed in this paper to represent the evolution of space policy. Space policy involves both the process of policy formation and policy change over time (e.g., emergence of commercialization) and the courses of action taken to achieve political (and technological) determined outcomes. The evolution of space policy over time takes place through policy change. On this basis, public policy processes over the course of the space-age have involved the mobilization of governmental resources, actors, and institutions. Concomitantly, nongovernmental actors, such as private corporations and commercial enterprises, increasingly play a role in space. As a result, market factors in addition to political forces influence space policy.

    Protein DataBank file format is used for the majority of biomolecular data available today. Haskell is a lazy functional language that enjoys a high-level class-based type system, a growing collection of useful libraries and a reputation for efficiency. I present a fast library for processing biomolecular data in the Protein Data Bank format. I present benchmarks indicating that this library is faster than other frequently used Protein Data Bank parsing programs. The proposed library also features a convenient iterator mechanism, and a simple API modeled after BioPython. I set a new standard for convenience and efficiency of Protein Data Bank processing in a Haskell library, and release it to open source.

    A blind frequency and phase search algorithm for joint frequency and phase recovery is introduced. The algorithm achieves low complexity due to processing in polar coordinates, which reduces the amount of multiplications. We show an implementation for real-time processing at 32 GBd on FPGA hardware. The hardware design allows for dynamic multi-format operation, where the format can be switched flexibly after each clock cycle (250 MHz, 128 Symbols) between 4QAM, 8QAM, and 16QAM. The performance of the algorithm is evaluated with respect to laser phase noise, carrier frequency offset, and carrier frequency offset drift. The effect of working with limited hardware resources is investigated. An FPGA implementation shows the feasibility of our carrier recovery algorithm with a negligible penalty when compared to a floating point simulation.

  19. Processes of Formation of Spheroidal Concretions and Inferences for "Blueberries" in Meridiani Planum Sediments

    2005-01-01

    The MER Opportunity Athena Science team has described spheroidal hematite nodules in sediments at Meridiani Planum on Mars [1]. They were informally referred to as "Blueberries" in the initial press releases and for brevity that is the name to be used in this abstract. Not all spheroidal objects in sediments are nodular concretions, but this paper will discuss the diagenetic processes possibly relevant to understanding the origin of the Blueberries. There are many occurrences of spheroidal diagenetic concretions in terrestrial sediments and detailed work has been done to understand the processes of their formation. In particular, it is possible to reconstruct the controls on their shapes and compositions, both mineral and chemical. Although there may not be good analogs for the Meridiani Planum hematite spherules on Earth, it may be possible to deduce the former environmental conditions that led to their formation and whether they might retain (or even be) biosignatures.

    Neither the routes through which humin byproducts are formed, nor their molecular structure have yet been unequivocally established. A better understanding of the formation and physicochemical properties of humins, however, would aid in making biomass conversion processes more efficient. Here, an extensive multiple-technique-based study of the formation, molecular structure, and morphology of humins is presented as a function of sugar feed, the presence of additives (e.g., 1,2,4-trihydroxybenzene), and the applied processing conditions. Elemental analyses indicate that humins are formed through a dehydration pathway, with humin formation and levulinic acid yields strongly depending on the processing parameters. The addition of implied intermediates to the feedstocks showed that furan and phenol compounds formed during the acid-catalyzed dehydration of sugars are indeed included in the humin structure. IR spectra, sheared sum projections of solid-state 2DPASS (13) C NMR spectra, and pyrolysis GC-MS data indicate that humins consist of a furan-rich polymer network containing different oxygen functional groups. The structure is furthermore found to strongly depend on the type of feedstock. A model for the molecular structure of humins is proposed based on the data presented.

    2007-05-08

    An advanced water treatment demonstration plant consisted of ozone/granular activated carbon processes was operated to study feasibility of the processes. Natural organic matter (NOM) from raw and process waters at the demonstration plant was isolated into humic and non-humic fractions by physicochemical fractionation method to investigate characteristics of humic fraction (i.e., humic substances, HS) as a predominant haloform reactant. Ozone did not significantly oxidize the carboxylic fraction (from 39.1 to 35.9%), while GAC removed some of the carboxylic fraction (from 35.9 to 29.1%). Formation potential of trihalomethanes (THMs) as compared to haloacetic acids formation potential (HAAFP) was highly influenced by HS. Higher yields of THMs resulted from chlorination of HS with a higher phenolic content and phenolic fraction in the HS gradually decreased from 60.5% to 15.8% through the water treatment. The structural and functional changes of HS were identified by elemental, Fourier-transform infrared (FT-IR) and proton nuclear magnetic resonance ((1)H NMR) analyses, and these results were mutually consistent. The functional distribution data obtained by using A-21 resin could be used to support the interpretation of data obtained from the spectroscopic analyses. Decreases in ratio of UV absorbance at 253 nm and 203 nm (A(253)/A(203)) and DBPFPs/DOC showed consistent trends, therefore, A(253)/A(203) ratio may be a good indicator for the disinfection by-product formation potentials (DBPFPs).

    The aims of this study were to identify how the solvent selection affects particle formation and to examine the effect of the initial drug solution concentration on mean particle size and particle size distribution in the supercritical antisolvent (SAS) process. Amorphous atorvastatin calcium was precipitated from seven different solvents using the SAS process. Particles with mean particle size ranging between 62.6 and 1493.7 nm were obtained by varying organic solvent type and solution concentration. By changing the solvent, we observed large variations in particle size and particle size distribution, accompanied by different particle morphologies. Particles obtained from acetone and tetrahydrofuran (THF) were compact and spherical fine particles, whereas those from N-methylpyrrolidone (NMP) and dimethylsulfoxide (DMSO) were agglomerated, with rough surfaces and relatively larger particle sizes. Interestingly, the mean particle size of atorvastatin calcium increased with an increase in the boiling point of the organic solvent used. Thus, for atorvastatin particle formation via the SAS process, particle size was determined mainly by evaporation of the organic solvent into the antisolvent phase. In addition, the mean particle size was increased with increasing drug solution concentration. In this study, from the aspects of particle size and solvent toxicity, acetone was the better organic solvent for controlling nanoparticle formation of atorvastatin calcium.

The cultural transmission model is useful for judging when people become sports lovers and how the sports lover share of a population changes because this model can analyze the process by which a naïve child receives various influences that form preferences. Moreover, we examine how public support of a sports team in one region affects the share of spo...

    The development of high energy (> 150 keV) neutral beams for heating and fueling magnetic fusion devices depends on the ability to produce well-collimated negative ion beams. The double capture charge-exchange technique is a known, scalable method. In order to maximize the overall efficiency of the process and to achieve the desired beam characteristics, it is necessary to examine the optical qualities of the beams as well as the total efficiency of beam production. A combined modeling and experimental study of the angular scattering effects in negative ion formation and loss processes has therefore been undertaken

    Despite significant differences in terms of medical training and health care context, the phenomenon of medical students' declining interest in family medicine has been well documented in North America and in many other developed countries as well. As part of a research program on family physicians' professional identity formation initiated in 2007, the purpose of the present investigation is to examine in-depth how family physicians construct their professional image in academic contexts; in other words, this study will allow us to identify and understand the processes whereby family physicians with an academic appointment seek to control the ideas others form about them as a professional group, i.e. impression management. The methodology consists of a multiple case study embedded in the perspective of institutional theory. Four international cases from Canada, France, Ireland and Spain will be conducted; the "case" is the medical school. Four levels of analysis will be considered: individual family physicians, interpersonal relationships, family physician professional group, and organization (medical school). Individual interviews and focus groups with academic family physicians will constitute the main technique for data generation, which will be complemented with a variety of documentary sources. Discourse techniques, more particularly rhetorical analysis, will be used to analyze the data gathered. Within- and cross-case analysis will then be performed. This empirical study is strongly grounded in theory and will contribute to the scant body of literature on family physicians' professional identity formation processes in medical schools. Findings will potentially have important implications for the practice of family medicine, medical education and health and educational policies.

    The process of ceramic formation from the two components namely flyash and feldspar as an alternative for the initial preparation of radioactive waste immobilization has been experimentally investigated. The process variables were : the weight ratio of flyash/feldspar : 50/50 -100/0, hydraulic press formation of flyash pellet : 25 -75 kN and the firing temperature: 1000 - 1300 o C with the firing rate in the furnace at 250 o C. The stage of processes covered the mixing of flyash-feldspar, pelletization, firing of pellet, physical analysis including porosity and compressive strength. The experimental results show that the quality of the best ceramic was at the process condition as the following : the ratio weight of flyash/feldspar was 50/50, the hydraulic press of pellet was 75 kN and the firing temperature of 1300 o C with the compressive strength of ceramic pellet of 27.5 kN/cm 2 and the porosity of 0.014. XRD analysis of mineral for the ceramic at the above condition processes showed that ceramic consist of minerals with the composition of 63.51 % mullite, 25.18 % alpha quartz/cristobalite and 10.51 % feldspar.

    Internationally, many health care interventions were diffused prior to the standard use of assessments of safety, effectiveness and cost-effectiveness. Disinvestment from ineffective or inappropriately applied practices is a growing priority for health care systems for reasons of improved quality of care and sustainability of resource allocation. In this paper we examine key challenges for disinvestment from these interventions and explore potential policy-related avenues to advance a disinvestment agenda. We examine five key challenges in the area of policy driven disinvestment: 1) lack of resources to support disinvestment policy mechanisms; 2) lack of reliable administrative mechanisms to identify and prioritise technologies and/or practices with uncertain clinical and cost-effectiveness; 3) political, clinical and social challenges to removing an established technology or practice; 4) lack of published studies with evidence demonstrating that existing technologies/practices provide little or no benefit (highlighting complexity of design) and; 5) inadequate resources to support a research agenda to advance disinvestment methods. Partnerships are required to involve government, professional colleges and relevant stakeholder groups to put disinvestment on the agenda. Such partnerships could foster awareness raising, collaboration and improved health outcome data generation and reporting. Dedicated funds and distinct processes could be established within the Medical Services Advisory Committee and Pharmaceutical Benefits Advisory Committee to, a) identify technologies and practices for which there is relative uncertainty that could be the basis for disinvestment analysis, and b) conduct disinvestment assessments of selected item(s) to address existing practices in an analogous manner to the current focus on new and emerging technology. Finally, dedicated funding and cross-disciplinary collaboration is necessary to build health services and policy research capacity

    India is undergoing a shift in consumption from traditional foods to processed foods high in sugar, salt and fat. Partially hydrogenated vegetable oils (PHVOs) high in trans-fat are often used in processed foods in India given their low cost and extended shelf life. The World Health Organization has called for the elimination of PHVOs from the global food supply and recommends their replacement with polyunsaturated fat to maximize health benefits. This study examined barriers to replacing industrially produced trans-fat in the Indian food supply and systematically identified potential policy solutions to assist the government in encouraging its removal and replacement with healthier polyunsaturated fat. A combination of food supply chain analysis and semi-structured interviews with key stakeholders was conducted. The main barriers faced by the food-processing sector in terms of reducing use of trans-fat and replacing it with healthier oils in India were the low availability and high cost of oils high in polyunsaturated fats leading to a reliance on palm oil (high in saturated fat) and the low use of those healthier oils in product reformulation. Improved integration between farmers and processors, investment in technology and pricing strategies to incentivize use of healthier oils for product reformulation were identified as policy options. Food processors have trouble accessing sufficient affordable healthy oils for product reformulation, but existing incentives aimed at supporting food processing could be tweaked to ensure a greater supply of healthy oils with the potential to improve population health. © The Author (2014).

    An important aim of the study of tsunami deposits is to estimate the characteristics of past tsunamis from the tsunami deposits found locally. Based on the tsunami characteristics estimated from tsunami deposit, it is possible to examine tsunami risk assessment in coastal areas. It is considered that tsunami deposits are formed based on the dynamic correlation between tsunami's hydraulic values, sediment particle size, topography, etc. However, it is currently not enough to evaluate the characteristics of tsunamis from tsunami deposits. This is considered to be one of the reasons that the understanding of the formation process of tsunami deposits is not sufficiently understood. In this study, we analyze the measurement results of hydraulic experiment (Yamamoto et al., 2016) and focus on the formation process and distribution of tsunami deposits. Hydraulic experiment was conducted with two-dimensional water channel with a slope. Tsunami was inputted as a bore wave flow. The moving floor section was installed as a seabed slope connecting to shoreline and grain size distribution was set some cases. The water level was measured using ultrasonic displacement gauges, and the flow velocity was measured using propeller current meters and an electromagnetic current meter. The water level and flow velocity was measured at some points. The distribution of tsunami deposit was measured from shoreline to run-up limit on the slope. Yamamoto et al. (2016) reported the measurement results on the distribution of tsunami deposit with wave height and sand grain size. Therefore, in this study, hydraulic analysis of tsunami sediment formation process was examined based on the measurement data. Time series fluctuation of hydraulic parameters such as Froude number, Shields number, Rouse number etc. was calculated to understand on the formation process of tsunami deposit. In the front part of the tsunami, the flow velocity take strong flow from shoreline to around the middle of slope. From

  14. Cloud processing of organic compounds: Secondary organic aerosol and nitrosamine formation

    Science.gov (United States)

    Hutchings, James W., III

    Cloud processing of atmospheric organic compounds has been investigated through field studies, laboratory experiments, and numerical modeling. Observational cloud chemistry studies were performed in northern Arizona and fog studies in central Pennsylvania. At both locations, the cloud and fogs showed low acidity due to neutralization by soil dust components (Arizona) and ammonia (Pennsylvania). The field observations showed substantial concentrations (20-5500 ng•L -1) of volatile organic compounds (VOC) in the cloud droplets. The potential generation of secondary organic aerosol mass through the processing of these anthropogenic VOCs was investigated through laboratory and modeling studies. Under simulated atmospheric conditions, in idealized solutions, benzene, toluene, ethylbenzene, and xylene (BTEX) degraded quickly in the aqueous phase with half lives of approximately three hours. The degradation process yielded less volatile products which would contribute to new aerosol mass upon cloud evaporation. However, when realistic cloud solutions containing natural organic matter were used in the experiments, the reaction kinetics decreased with increasing organic carbon content, resulting in half lives of approximately 7 hours. The secondary organic aerosol (SUA) mass formation potential of cloud processing of BTEX was evaluated. SOA mass formation by cloud processing of BTEX, while strongly dependent on the atmospheric conditions, could contribute up to 9% of the ambient atmospheric aerosol mass, although typically ˜1% appears realistic. Field observations also showed the occurrence of N-nitrosodimethylamine (NDMA), a potent carcinogen, in fogs and clouds (100-340 ng•L -1). Laboratory studies were conducted to investigate the formation of NDMA from nitrous acid and dimethylamine in the homogeneous aqueous phase within cloud droplets. While NDMA was produced in the cloud droplets, the low yields (<1%) observed could not explain observational concentrations

    Melt pond formation atop Arctic sea ice is a primary control of shortwave energy balance in the Arctic Ocean. During late spring and summer, the ponds determine sea ice albedo and how much solar radiation is transmitted into the upper ocean through the sea ice. The initial formation of ponds requires that melt water be retained above sea level on the ice surface. Both theory and observations, however, show that first year sea ice is so highly porous prior to the formation of melt ponds that multiday retention of water above hydraulic equilibrium should not be possible. Here we present results of percolation experiments that identify and directly demonstrate a mechanism allowing melt pond formation. The infiltration of fresh water into the pore structure of sea ice is responsible for blocking percolation pathways with ice, sealing the ice against water percolation, and allowing water to pool above sea level. We demonstrate that this mechanism is dependent on fresh water availability, known to be predominantly from snowmelt, and ice temperature at melt onset. We argue that the blockage process has the potential to exert significant control over interannual variability in ice albedo. Finally, we suggest that incorporating the mechanism into models would enhance their physical realism. Full treatment would be complex. We provide a simple temperature threshold-based scheme that may be used to incorporate percolation blockage behavior into existing model frameworks.

    In the present study, laser-brazed AA6082 to DX56-galvanized steel joints were investigated to understand the influence of process parameters on joint strength in terms of intermetallic layer formation. 1.5-mm-thick sheet of aluminum alloy (AA6082-T6) and galvanized steel (DX56) sheet of 0.7 mm thickness were laser-brazed with 1.5-mm-diameter Al-12% Si solid filler wire. During laser brazing, laser power (4.6 kW) and wire feed rate (3.4 m/min) were kept constant with a varying laser scan speed of 3.5, 3, 2.5, 2, 1.5, and 1 m/min. Microstructure of brazed joint reveals epitaxial growth at the aluminum side and intermetallic layer formation at steel interface. Intermetallic layer formation was confirmed by EDS analysis and XRD study. Hardness profile showed hardness drop in filler region, and failure during tensile testing was initiated through the filler region near the steel interface. As per both experimental study and numerical analysis, it was observed that intermetallic layer thickness decreases with increasing brazing speed. Zn vaporization from galvanized steel interface also affected the joint strength. It was found that high laser scan speed or faster cooling rate can be chosen for suppressing intermetallic layer formation or at least decreasing the layer thickness which results in improved mechanical properties.

    Full Text Available In research field of development processes of architectural and construction decisions (ACD there is already very considerable scientific, normative and technical material. And still in the end of the research boom in this area (the 90th many authors stated their weak return in practical design. High methodological potential gives understanding of the act of ACD formation as a special kind of activity, and its structure - as historical phenomenon that allows to put two main methodological principles in the basis of the research: the principle of activity and the principle of level organization of historically formed objects. As a result it was succeeded to reveal 6 main stages of historical development of ACD formation process and 6 levels of its modern organization. Origin stage - is the transition from animal to human construction and emergence of the first stage of ACD formation - a measurement. The reproductive stage is characterized by centuries-old reproduction of steady volume forms of constructions. At a composite stage professional presentation detaches external form of a construction from architectural and construction actions and techniques. There occurs transformation into a subject of architectural and construction activity and creation of a method of composition on this basis. At a constructive stage engineers are involved in construction process, there is a change of style of thinking, emergence of construction designs and emergence of a new function of ACD means of configuration, and, at last, final allocation and separation of architectural and construction design from construction. Technological stage is a product of industrialization of construction on which systematization is carried out not only on the level of subject, but also in respect to the operational contents that leads to emergence of ACD program formation. At the sixth, methodological stage of development of ASP, a leading way change of the ACD formation becomes a

    Full Text Available Interest in the potential formation of secondary organic aerosol (SOA through reactions of organic compounds in condensed aqueous phases is growing. In this study, the potential formation of SOA from irreversible aqueous-phase reactions of organic species in clouds was investigated. A new proposed aqueous-phase chemistry mechanism (AqChem is coupled with the existing gas-phase Caltech Atmospheric Chemistry Mechanism (CACM and the Model to Predict the Multiphase Partitioning of Organics (MPMPO that simulate SOA formation. AqChem treats irreversible organic reactions that lead mainly to the formation of carboxylic acids, which are usually less volatile than the corresponding aldehydic compounds. Zero-dimensional model simulations were performed for tropospheric conditions with clouds present for three consecutive hours per day. Zero-dimensional model simulations show that 48-h average SOA formation is increased by 27% for a rural scenario with strong monoterpene emissions and 7% for an urban scenario with strong emissions of aromatic compounds, respectively, when irreversible organic reactions in clouds are considered. AqChem was also incorporated into the Community Multiscale Air Quality Model (CMAQ version 4.4 with CACM/MPMPO and applied to a previously studied photochemical episode (3–4 August 2004 focusing on the eastern United States. The CMAQ study indicates that the maximum contribution of SOA formation from irreversible reactions of organics in clouds is 0.28 μg m−3 for 24-h average concentrations and 0.60 μg m−3 for one-hour average concentrations at certain locations. On average, domain-wide surface SOA predictions for the episode are increased by 9% when irreversible, in-cloud processing of organics is considered. Because aldehydes of carbon number greater than four are assumed to convert fully to the corresponding carboxylic acids upon reaction with OH in cloud droplets and this assumption may overestimate

    This commentary reflects upon the article along three broad lines. It reflects on the theoretical choices and omissions, particularly highlighting why it is important to adapt the multiple streams framework (MSF) when applying it in a socio-political context like Vietnam's. The commentary also reflects upon the analytical threads tackled by Ha et al; for instance, it highlights the opportunities offered by, and raises questions about the centrality of the Policy Entrepreneur in getting the policy onto the political agenda and in pushing it through. The commentary also dwells on the implications of the article for development aid policies and practices. Throughout, the commentary signposts possible themes for Ha et al to consider for further analysis, and more generally, for future research using Kingdon's multiple streams theory. © 2016 by Kerman University of Medical Sciences.

    2016-10-13

    Theories of the policy process are recommended as tools to help explain both policy stasis and change. A systematic review of the application of such theoretical frameworks within the field of obesity prevention policy was conducted. A meta-synthesis was also undertaken to identify the key influences on policy decision-making. The review identified 17 studies of obesity prevention policy underpinned by political science theories. The majority of included studies were conducted in the United States (US), with significant heterogeneity in terms of policy level (e.g., national, state) studied, areas of focus, and methodologies used. Many of the included studies were methodologically limited, in regard to rigour and trustworthiness. Prominent themes identified included the role of groups and networks, political institutions, and political system characteristics, issue framing, the use of evidence, personal values and beliefs, prevailing political ideology, and timing. The limited application of political science theories indicates a need for future theoretically based research into the complexity of policy-making and multiple influences on obesity prevention policy processes.

    Full Text Available Background and Objectives : Agenda setting is the process by which certain issues come onto the policy agenda from the much larger number of issues potentially worthy of attention by policy makers. The aim of this study was to deeply understand about how AIDS entered to health policy agenda in Iran. Material and Methods: An exploratory qualitative retrospective study based on multiple streams framework to analyze AIDS agenda setting process, 32 semi-structured interviews were conducted with key informants and stakeholders in Iran and 30 policy documents were reviewed. Data were analyzed using framework analysis method and MAXQDA software. Results : Problem, policy and politics, the three streams of HIV/AIDS in context of Iran were identified and the advent and continuity of multiple streams and their interactions and combination by policy entrepreneurs in couple of streams in policy windows were explained. Conclusion: In this study, the assumption of independence of three streams from each other was doubted. Also, framework has ambiguities in explaining entrepreneurs' act when opening policy windows. Other researchers can modify the framework by learning-by-doing.

    2013-01-01

    In order to clarify the influence of electrostatic forces caused by charging of particles on the coagulation process in fume formation in arc welding, a previously developed fume formation model is modified to consider the influence of charging, for both local thermodynamic equilibrium (LTE) and non-LTE conditions. The model takes into account formation of the particles from metal vapour by nucleation, growth of the particles by condensation of metal vapour and coagulation of the particles by collisions to form secondary particles. Results are obtained for both ballistic and Brownian motion of the particles. It is found that the growth of secondary particles is suppressed when the average particle charge becomes significant, because charging of the particle hinders collisions among secondary particles through the strong repulsive electrostatic force. Furthermore, deviations from LTE strongly affect the coagulation process, because the increased electron density at a given gas temperature increases the charging of particles. Brownian motion leads to larger secondary particles, since the average particle speed is increased. The influence of Brownian motion and particle charging cancel each other to a large extent, particularly when deviations from LTE are considered. (paper)

  5. The role of reconsolidation and the dynamic process of long-term memory formation and storage

    Cristina M Alberini

    2011-03-01

    Full Text Available It is becoming increasingly clear that the processes of memory formation and storage are exquisitely dynamic. Elucidating the nature and temporal evolution of the biological changes that accompany encoding, storage and retrieval is key to understand memory formation. For explicit or medial temporal lobe-dependent memories that form after a discrete event and are stored for a long time, the physical changes underlying the encoding and processing of the information (memory trace or engram remain in a fragile state for some time. However, over time, the new memory becomes increasingly resistant to disruption until it is consolidated. Retrieval or reactivation of an apparently consolidated memory can render the memory labile again, and reconsolidation is the process that occurs to mediate its restabilization. Reconsolidation also evolves with the age of the memory: Young memories are sensitive to postreactivation disruption, but older memories are more resistant. Why does a memory become labile again if it is retrieved or reactivated? Here I suggest that the main function of reconsolidation is to contribute to the lingering consolidation process and mediate memory strengthening. I also discuss the literature and results regarding the influence of the passage of time on the reconsolidation of memory. These points have important implications for the use of reconsolidation in therapeutic settings.

  6. Microstructures and formation mechanism of hypoeutectic white cast iron by isothermal electromagnetic rheocast process

    2010-05-01

    Full Text Available An investigation was made on the evolution of microstructures of hypoeutectic white cast iron slurry containing 2.5wt.%C and 1.8wt.%Si produced by rheocasting in which the solidifying alloy was vigorously agitated by electromagnetic stirrer during isothermal cooling processes. The results indicated that under the proper agitating temperatures and speeds applied, the dendrite structures in white cast iron slurry were gradually evolved into spherical structures during a certain agitating time. It also revealed that the bent dendrites were formed by either convection force or by the growth of the dendrites themselves in the bending direction; then, as they were in solidifying, they were gradually being alternated into separated particles and into more spherical structures at the end of the isothermal cooling process. Especially, the dendrites were granulated as the bending process proceeding, which suggested that they were caused by unwanted elements such as sulfur and phosphor usually contained in engineering cast iron. Convective flow of the melt caused corrosion on the dendritic segments where they were weaker in strength and lower in melting temperature because of higher concentration of sulfur or phosphor. And the granulation process for such dendrites formed in the melt became possible under the condition. Certainly, dendrite fragments are another factors considerable to function for spherical particles formation. A new mechanism, regarding to the rheocast structure formation of white cast iron, was suggested based on the structural evolution observed in the study.

    2018-01-01

    This paper seeks to clarify the weld pool formation process in plasma keyhole arc welding (PKAW). We adopted, for the first time, the measurement of the 3D convection inside the weld pool in PKAW by stereo synchronous imaging of tungsten tracer particles using two sets of x-ray transmission systems. The 2D convection on the weld pool surface was also measured using zirconia tracer particles. Through these measurements, the convection in a wide range of weld pools from the vicinity of the keyhole to the rear region was successfully visualized. In order to discuss the heat transport process in a weld pool, the 2D temperature distribution on the weld pool surface was also measured by two-color pyrometry. The results of the comprehensive experimental measurement indicate that the shear force due to plasma flow is found to be the dominant driving force in the weld pool formation process in PKAW. Thus, heat transport in a weld pool is considered to be governed by two large convective patterns near the keyhole: (1) eddy pairs on the surface (perpendicular to the torch axis), and (2) eddy pairs on the bulk of the weld pool (on the plane of the torch). They are formed with an equal velocity of approximately 0.35 m s‑1 and are mainly driven by shear force. Furthermore, the flow velocity of the weld pool convection becomes considerably higher than that of other welding processes, such as TIG welding and GMA welding, due to larger plasma flow velocity.

  8. Limits Imposed on Heat Produced during Core Formation by Radiative Transfer Processes and Thermodynamic Laws

    Criss, R. E.; Hofmeister, A.

    2010-12-01

    The popular view that Earth is sufficiently hot to still be shedding primordal heat, largely originating in the core, is inconsistent with thermodynamic constraints and recent heat transport studies. Previous work presumes that the large difference in gravitational potential energy (Ug) between a fictious, homogeneous reference state and Earth’s current layered configuration of metallic core and rocky mantle was converted to frictional heat during core formation, greatly increasing temperature (T) inside the Earth. However, heating (ΔT >0) was deduced by assuming that Ug is positive, which is inconsistent with Newton’s law of gravitation. Use of an erroneous sign for ΔUg has prevented recognition that the process is an exothermic transformation. Thermodynamic principles were not considered in previous analyses: neglecting the effect of the change in configuration on entropy and energy contributes greatly to the view that heat is retained. Instead, stringent limits are set on the permissible temperature increase by the rapid rate of ballistic radiative transfer, a process associated with transient events, as well as by the 1st and 2nd laws of thermodynamics. In the static, instantaneous model of core formation, configurational entropy (S) of the Earth decreases upon forming the ordered layered state; this entropy decrease is offset by a greater increase in S of the surrounding universe, which can only be accomplished by release of heat to space (the surroundings). Instantaneous dissipation of heat in the static model reasonably approximates radiative processes being superfast. Core formation involves negligible changes in volume and rotational energy, so Helmholtz free energy (=Ug-TS) is conserved, as in atmospheric processes and other graviational-thermodynamic problems. Because S of the universe is immense and heat must flow from hotter to colder bodies, negligible heat from core formation is retained, consistent with the exothermic nature of this transition

    Highly siderophile elements (HSE = Au, Re, and the Pt-group elements) are tracers of silicate / metal interactions during planetary processes. Since most core-formation models involve some state of equilibrium between liquid silicate and liquid metal, understanding the partioning of highly siderophile elements (HSE) between silicate and metallic melts is a key issue for models of core / mantle equilibria and for core formation scenarios. However, partitioning models for HSE are still inaccurate due to the lack of sufficient experimental constraints to describe the variations of partitioning with key variable like temperature, pressure, and oxygen fugacity. In this abstract, we describe a self-consistent set of experiments aimed at determining the valence of platinum, one of the HSE, in silicate melts. This is a key information required to parameterize the evolution of platinum partitioning with oxygen fugacity.

    Advanced fuel cycles all over the world rely heavily on successful chemical separation of various elements in used nuclear fuel. Numerous solvent extraction processes have been developed for the treatment of this material. Under certain conditions the extraction systems may behave different from classical solvent extraction theory. One chemical interaction of interest is the formation of large aggregates that has been observed during solvent extraction. In our work, we are studying the effect and relationship of extensive aggregate formation with enhanced extraction of metal ions, i.e. synergistic extraction. Our studies so far have shown the importance of combining and comparing several different analytical techniques, such as metal ion extraction, physicochemical measurements, thermodynamics studies and structural investigations. Overall, the results do not disagree with classic understanding of extraction synergy although there appear to be additional chemical interactions that may affect the distribution of metal ions prompting further studies.

    Full Text Available Utilizando la mayor muestra de galaxias con líneas de emisión angostas disponible hasta el momento, se muestra que sus características espectrales están correlacionadas con diferentes parámetros físicos, como las abundancias químicas, las morfologías, las masas del bulbo, y la edad estelar promedio de las poblaciones estelares de la galaxia anfitriona. Por lo tanto, se sugiere que las variaciones espectrales observadas en diagramas de diagnóstico estándares no se deben únicamente a las variaciones de los parámetros o las estructuras de ionización, sino que reflejan también la evolución química de las galaxias, relacionada con diferentes procesos de formación.  Using the largest sample of narrow emission line galaxies available so far, we show that their spectral characteristics are correlated with different physical parameters, like the chemical abundances, the morphologies, the masses of the bulge and the mean stellar age of the stellar populations of the host galaxies. It suggests that the spectral variations observed in standard spectroscopic diagnostic diagrams are not due solely to variations of ionization parameters or structures but reflect also the chemical evolution of the galaxies, which in turn can be explained by different galaxy formation processes.

    Shisha smoking is a widespread custom in Iran with a rapidly growing prevalence especially among the youth. In this article, we analyze the policy process of enforcing a federal/state ban on shisha smoking in all public places in Kerman Province, Iran. Guided by the Advocacy Coalition Framework (ACF), we investigate how a shisha smoking ban reached the political agenda in 2011, how it was framed by different policy actors, and why no significant breakthrough took place despite its inclusion on the agenda. We conducted a qualitative study using a case study approach. Two main sources of data were employed: face-to-face in-depth interviews and document analysis of key policy texts. We interviewed 24 policy actors from diverse sectors. A qualitative thematic framework, incorporating both inductive and deductive analyses, was employed to analyze our data. We found that the health sector was the main actor pushing the issue of shisha smoking onto the political agenda by framing it as a public health risk. The health sector and its allies advocated enforcement of a federal law to ban shisha smoking in all public places including teahouses and traditional restaurants whereas another group of actors opposed the ban. The pro-ban group was unable to neutralize the strategies of the anti-ban group and to steer the debate towards the health harms of shisha smoking. Our analysis uncovers three main reasons behind the policy stasis: lack of policy learning due to lack of agreement over evidence and related analytical conflicts between the two groups linked to differences in core and policy beliefs; the inability of the pro-ban group to exploit opportunities in the external policy subsystem through generating stronger public support for enforcement of the shisha smoking ban; and the nature of the institutional setting, in particular the autocratic governance of CHFS which contributed to a lack of policy learning within the policy subsystem. Our research demonstrated the utility

    In limited dopant source diffusion process, the deposition and the drive in conditions of the source play an important role in pn- junction formation. The pre diffusion anomalies can introduce defects in the emitter region during the process of diffusion which can glide into the bulk region. So, the defects formed in the emitter region due to different pre diffusion issues are studied in this work with boron spin on dopant source diffused in n-type crystalline Si. The samples are prepared for different diffusion conditions of times carried out at diffusion temperature of 900°C. Different characterization techniques used in this work confirms the presence of these defects in the emitter region. The dopant distribution under the same diffusion condition result in non- uniformity, varying the junction depth of the emitter. A single process step anomaly is sufficient enough to degrade the emitter performance and should be avoided.

    This article provides an approach to improve and control crystal phases of the sputtering vanadium oxide (VxOy) thin films by post-thermal annealing process. Usually, as-deposited VxOy thin films at room temperature are amorphous phase: post-thermal annealing processes (400 °C, 2 hrs) under the various nitrogen (N2) pressures are applied to improve and control the crystal phase of VxOy thin films. The crystallinity of VxOy thin films changes from amorphous to α-V2O5 phase or V9O17 polycrystalline, which depend on the pressure of N2 carrier during annealing process. Moreover, the electrical resistivity of the VxOy thin films decrease from 105 Ω cm (amorphous) to 6×10-1 Ω cm (V9O17). Base on the results, our study show a simply method to improve and control phase formation of VxOy thin films.

    Directional solidification experiments were performed, using succinonitrile saturated with nitrogen gas, to examine the effects of in-situ processing pressure changes on the formation growth, and evolution of an isolated, cylindrical gaseous pore. A novel solidification facility, capable of processing thin cylindrical samples (I.D. pressure conditions, was used for the experiments. A new experimental method for growing the isolated pore from a seed bubble is introduced. The experimental results indicate that an in-situ processing pressure change will result in either a transient change in pore diameter or a complete termination of pore growth, indicating that pressure changes can be used as a control parameter to terminate bubble growth. A simple analytical model has been introduced to explain the experimental observations.

    Cervical cancer is the second most common cancer in women around the world, and the human papillomavirus (HPV) is universally known as the necessary agent for developing this disease. Through early detection of abnormal cells and HPV virus types, cervical cancer incidents can be reduced and disease progression prevented. We propose a finite-horizon Markov decision process model to determine the optimal screening policies for cervical cancer prevention. The optimal decision is given in terms of when and what type of screening test to be performed on a patient based on her current diagnosis, age, HPV contraction risk, and screening test results. The cost function considers the tradeoff between the cost of prevention and treatment procedures and the risk of taking no action while taking into account a cost assigned to loss of life quality in each state. We apply the model to data collected from a representative sample of 1141 affiliates at a health care provider located in Bogotá, Colombia. To track the disease incidence more effectively and avoid higher cancer rates and future costs, the optimal policies recommend more frequent colposcopies and Pap tests for women with riskier profiles.

    Full Text Available Since 1979, foreign- and security-policy-making and implementation processes have gradually and substantially changed. New modes of operation that have consolidated under Hu Jintao, actually took shape under Jiang Zemin in the 1990s, and some, under Deng Xiaoping. While the military’s role has diminished, that of diplomats, experts, and bureaucracies dealing with trade, international economic relations, energy, propaganda and education has increased. Decision making in this area has remained highly centralized and concentrated in the supreme leading bodies of the Chinese Communist Party (CCP. However, China’s globalization and decentralization, as well as the increasing complexity of its international interests, have intensified the need to better coordinate the activities of the various CCP and state organs involved in foreign and security policy; hence, the growing importance of the CCP leading small groups (foreign affairs, national security, Taiwan, etc.. But the rigidity of the current institutional pattern has so far foiled repeated attempts to establish a National Security Council.

    This is a qualitative descriptive exploratory study, conducted in Higher Education Institutions (HEI) which offers Nursing course, in Joao Pessoa-PB. The study aimed to understand the concept of managers about the need for organizational changes to attend customers with special needs. Four managers participated in the study. A semi-structured interview with guiding questions was used to collect information and to interpret the data we used the method of discourse analysis based on Fiorin. It was noticed that the managers have a concern to meet the demands of inclusive policies, including the adequacy of physical spaces and the pedagogy adopted to meet the students' needs. However, some of them admitted to have little knowledge on how to deal with students with special needs and also mentioned that the institutions do not have an efficient and logistic work which can meet the current legislation of inclusion. We concluded that the process of structural and pedagogical changes is built in a slow and gradual way and it requires an involvement of qualified managers who are committed to execute the policies of inclusion of customers with special needs in a civil and legal way.

  19. Social acceptability of climate change policies; will energy efficiency always fail to win its case through the consultation process? Volume 1

    2007-01-01

    Which segments of society 'win' as a result of climate change policies? Actors generally support the principle of reduced emissions through decarbonising fuels, and many are convinced that reducing overall energy consumption is an essential strategy to prevent further damaging climate change. However, proposed strategies for ensuring that sufficient action is taken to reduce emissions suffer from complexity, uncertainty and dissent, especially from vested interests. The policy maker has to choose between many options, and many conflicting consultation responses, to select the most politically feasible and socially acceptable pathway. An FP6 funded project into Adaptation and Mitigation Strategies for climate change is developing an innovative tool to support policy choice based on a mix of methods, using case studies to test the outputs. Resources include stakeholder deliberation on criteria necessary to evaluate pathway options. The first stage maps energy actors' perspectives of climate change, identifying key issues for socially acceptable policies for the 2012 - 2050 period that would either limit climate change to only 2 deg C increase, or provide a 'soft landing' to a world 5 degrees above present.This paper describes this mapping exercise and indicates the issues of most debate, on which rest the criteria for social acceptability. It describes how deliberative methods can involve stakeholders more effectively in policy formation, contrasts the roles of deliberation and consultation, and discusses the engagement of powerful vested interests with this approach. While there are considerable overlaps in perspectives of different actors, leading to specific points of contention, importantly, decisions on selection and engagement of stakeholders with the process become critical if the criteria for policy decisions are to be accepted by society

    Nowadays numerical simulation of thundercloud formation processes is of great interest as an actual problem from the practical point of view. Thunderclouds significantly affect airplane flights, and mesoscale weather forecast has much to contribute to facilitate the aviation forecast procedures. An accurate forecast can certainly help to avoid aviation accidents due to weather conditions. The present study focuses on modelling of the convective clouds development and thunder clouds detection on the basis of mesoscale atmospheric processes simulation, aiming at significantly improving the aeronautical forecast. In the analysis, the primary weather radar information has been used to be further adapted for mesoscale forecast systems. Two types of domains have been selected for modelling: an internal one (with radius of 8 km), and an external one (with radius of 300 km). The internal domain has been directly applied to study the local clouds development, and the external domain data has been treated as initial and final conditions for cloud cover formation. The domain height has been chosen according to the civil aviation forecast data (i.e. not exceeding 14 km). Simulations of weather conditions and local clouds development have been made within selected domains with the WRF modelling system. In several cases, thunderclouds are detected within the convective clouds. To specify the given category of clouds, we employ a simulation technique of solid phase formation processes in the atmosphere. Based on modelling results, we construct vertical profiles indicating the amount of solid phase in the atmosphere. Furthermore, we obtain profiles demonstrating the amount of ice particles and large particles (hailstones). While simulating the processes of solid phase formation, we investigate vertical and horizontal air flows. Consequently, we attempt to separate the total amount of solid phase into categories of small ice particles, large ice particles and hailstones. Also, we

    some offset protocols award credits for activities that would have occurred anyway; by replacing a company's need to acquire an allowance in the carbon market, critics believe that poorly designed offset protocols increase greenhouse gas emissions. Thus, the effectiveness of the policy approach depends on the scientific integrity of the offset protocols. To date, California has approved offset protocols for emissions reductions in four applications: (1) forestry, (2) urban forestry, (3) livestock, and (4) destruction of ozone-depleting substances. In addition, the State is currently considering protocols that would address (5) methane emissions from mining and (6) greenhouse gas reductions from improved rice cultivation practices. These protocols rely heavily on findings from the environmental and earth sciences communities, especially when the protocol subject involves land use or land use change. Yet, due to budget constraints, the Air Resources Board is relying primarily on third-party protocol developers to design and propose the detailed structures under which offset credits will be issued. Despite the fact that any member of the public may participate in the governance regime that leads to protocol approvals, few scientists or scientific organizations provide input into the policy process. We use case studies from several of the California protocols to illustrate ways scientists can apply their skills to a crucial stage of climate policy development.

    Potentially toxic acrylamide is largely derived from the heat-inducing reactions between the amino group of the amino acid asparagine and carbonyl groups of glucose and fructose in plant-derived foods including cereals, coffees, almonds, olives, potatoes, and sweet potatoes. This review surveys and consolidates the following dietary aspects of acrylamide: distribution in food, exposure and consumption by diverse populations, reduction of the content in different food categories, and mitigation of adverse in vivo effects. Methods to reduce acrylamide levels include selecting commercial food with a low acrylamide content, selecting cereal and potato varieties with low levels of asparagine and reducing sugars, selecting processing conditions that minimize acrylamide formation, adding food-compatible compounds and plant extracts to food formulations before processing that inhibit acrylamide formation during processing of cereal products, coffees, teas, olives, almonds, and potato products, and reducing multiorgan toxicity (antifertility, carcinogenicity, neurotoxicity, teratogenicity). The herein described observations and recommendations are of scientific interest for food chemistry, pharmacology, and toxicology, but also have the potential to benefit nutrition, food safety, and human health.

    It is important to consider the interweaving nature of online and offline social networks when we examine social network evolution. However, it is difficult to find any research that examines the process of social tie formation from an integrated perspective. In our study, we quantitatively measure offline interactions and examine the corresponding evolution of online social network in order to understand the significance of interrelationship between online and offline social factors in generating social ties. We analyze the radio signal strength indicator sensor data from a series of social events to understand offline interactions among the participants and measure the structural attributes of their existing online Facebook social networks. By monitoring the changes in their online social networks before and after offline interactions in a series of social events, we verify that the ability to develop an offline interaction into an online friendship is tied to the number of social connections that participants previously had, while the presence of shared mutual friends between a pair of participants disrupts potential new connections within the pre-designed offline social events. Thus, while our integrative approach enables us to confirm the theory of preferential attachment in the process of network formation, the common neighbor theory is not supported. Our dual-dimensional network analysis allows us to observe the actual process of social network evolution rather than to make predictions based on the assumption of self-organizing networks.

    Complete text of publication follows. The thermal decomposition processes of the polymer-salt solutions of ammonium molybdate and wolframate are the basic methods to synthesize the powder catalysts MoO 3 and WO 3 . The results of the investigations of these processes by small angle neutron scattering and X-ray diffraction methods are presented. The parameters of the crystal structure of the oxide phase particles, a particle size distribution function, a specific surface and fractal dimension of particles surface, a volume part and mean particle size have been obtained. It is shown that the best catalytic properties are reached by heating initial samples up to 400 deg C. This state is defined by the mean particle size ∼ 15 nm, the specific surface ∼ 10 m 2 /g, the volume concentrations of particles ∼ 5 x 10 -2 and the fractal dimension of particles surface ∼ 2,5. A general mechanism for the formation of the oxide phases from different polymer-salt solution are established. The processes of the oxide phase formations occurs as the phase transition of the first kind, is also shown. This work has partly supported by state program 'Neutron Matter Investigations' (Project N96/104 and 96/305). (author)

  5. An efficient means to mitigate wavefront curvature effects in polar format processed SAR imagery

    2012-06-01

    Synthetic aperture radar (SAR) images processed using the polar format algorithm (PFA) may exhibit distortion if the curvature of the spherical wavefronts are not accounted for. The distortion manifests in geometric shifts and defocusing of targets, and intensifies as distances between pixels and the scene reference position increase. In this work, we demonstrate a method to mitigate the effects of wavefront curvature by applying localized (space-variant) phase corrections to sub-regions selected from the polar format processed image. The modified sub-images are then reassembled into a full image. To minimize discontinuities in the reconstructed image, the spatially variant phase adjustments are made to regions larger than the sub-images, and pared down before being reinserted into the complete image. The result is a SAR process that retains the efficiency of the PFA, yet avoids scene size limitations due to wavefront curvature distortions. The method is illustrated and validated using simulations and real data collected by the General Atomics Aeronautical Systems, Inc. (GA-ASI) Lynx® Multi-mode Radar System.

    2000-01-01

    1 - Description of program or function: The NJOY nuclear data processing system is a modular computer code used for converting evaluated nuclear data in the ENDF format into libraries useful for applications calculations. Because the Evaluated Nuclear Data File (ENDF) format is used all around the world (e.g., ENDF/B-VI in the US, JEF-2.2 in Europe, JENDL-3.2 in Japan, BROND-2.2 in Russia), NJOY gives its users access to a wide variety of the most up-to-date nuclear data. NJOY provides comprehensive capabilities for processing evaluated data, and it can serve applications ranging from continuous-energy Monte Carlo (MCNP), through deterministic transport codes (DANT, ANISN, DORT), to reactor lattice codes (WIMS, EPRI). NJOY handles a wide variety of nuclear effects, including resonances, Doppler broadening, heating (KERMA), radiation damage, thermal scattering (even cold moderators), gas production, neutrons and charged particles, photo-atomic interactions, self shielding, probability tables, photon production, and high-energy interactions (to 150 MeV). Output can include printed listings, special library files for applications, and Postscript graphics (plus color). More information on NJOY is available from the developer's home page at http://t2.lanl.gov/tour/tourbus.html. Follow the Tourbus section of the Tour area to find notes from the ICTP lectures held at Trieste in March 2000 on the ENDF format and on the NJOY code. NJOY contains the following modules: NJOY directs the flow of data through the other modules and contains a library of common functions and subroutines used by the other modules. RECONR reconstructs pointwise (energy-dependent) cross sections from ENDF resonance parameters and interpolation schemes. BROADR Doppler broadens and thins pointwise cross sections. UNRESR computes effective self-shielded pointwise cross sections in the unresolved energy range. HEATR generates pointwise heat production cross sections (KERMA coefficients) and radiation

    2014-01-01

    In this book, Benjamin Farrand employs an interdisciplinary approach that combines legal analysis with political theory to explore the development of copyright law in the EU. Farrand utilises Foucault's concept of Networks of Power and Culpepper's Quiet Politics to assess the adoption and enforcement of copyright law in the EU, including the role of industry representative, cross-border licensing, and judicial approaches to territorial restrictions. Focusing in particular on legislative initiatives concerning copyright, digital music and the internet, Networks of Power in Digital Copyright Law and Policy: Political Salience, Expertise and the Legislative Process demonstrates the connection between copyright law and complex network relationships. This book presents an original socio-political theoretical framework for assessing developments in copyright law that will interest researchers and post-graduate students of law and politics, as well as those more particularly concerned with political theory, EU and c...

  8. Automated system function allocation and display format: Task information processing requirements

    Science.gov (United States)

    Czerwinski, Mary P.

    1993-01-01

    An important consideration when designing the interface to an intelligent system concerns function allocation between the system and the user. The display of information could be held constant, or 'fixed', leaving the user with the task of searching through all of the available information, integrating it, and classifying the data into a known system state. On the other hand, the system, based on its own intelligent diagnosis, could display only relevant information in order to reduce the user's search set. The user would still be left the task of perceiving and integrating the data and classifying it into the appropriate system state. Finally, the system could display the patterns of data. In this scenario, the task of integrating the data is carried out by the system, and the user's information processing load is reduced, leaving only the tasks of perception and classification of the patterns of data. Humans are especially adept at this form of display processing. Although others have examined the relative effectiveness of alphanumeric and graphical display formats, it is interesting to reexamine this issue together with the function allocation problem. Currently, Johnson Space Center is the test site for an intelligent Thermal Control System (TCS), TEXSYS, being tested for use with Space Station Freedom. Expert TCS engineers, as well as novices, were asked to classify several displays of TEXSYS data into various system states (including nominal and anomalous states). Three different display formats were used: fixed, subset, and graphical. The hypothesis tested was that the graphical displays would provide for fewer errors and faster classification times by both experts and novices, regardless of the kind of system state represented within the display. The subset displays were hypothesized to be the second most effective display format/function allocation condition, based on the fact that the search set is reduced in these displays. Both the subset and the

    Full text: It is known, under interaction of laser radiation with solid surface a power density q > 0.01 W/cm 2 are observed destruction of a solid and issue of electrons, ions, neutrals, neutrons, plasmas, and also radiation in a wide ranges of a spectra. Despite of a plenty of works, devoted to study of processes of interaction, the studies of feature of destruction of solids by laser beam in process of formation multiply charged ions are insufficiently investigated. The results of study feature of destruction of solids by laser radiation in process of formation multiply charged ions are given in this work. In our experiments, we used the mass spectrometer with single-channel laser radiation. The laser installation had the following parameters: a power density of laser radiation q=(0.1-50) GW/cm 2 ; the angle of incidence a=18 deg. to the target surface Al, (W). It was obtained experimentally dynamics of morphology of destruction and also mass - charge and energy spectra of multiply charged ions formed under interaction of laser radiation with Al (W) in the intensity range q=(0.1-50) GW/cm 2 . These studies showed features of destruction Al(W) by laser radiation, i.e. invariable of value evaporation mass from a surface of a solid increase as the laser intensity q. But thus temperature a pair increases in accordance with increase of flow density of a laser radiation. Increase of temperature the pair gives in formation of multiply charged plasma. It is typical that, as q of the laser increases the maximum charge number of ions in laser plasma considerably increase and their energy spectra extend toward higher energies. For example, under q=0.1 GW/cm 2 and 50 GW/cm 2 the maximum charge number of ions Al (W) are equal to Z max = 1 and 7, respectively. From the experimental data obtained, we can conclude that, the formed multiply charged plasma practically completely absorption laser radiation and 'shielding' a target surface for various metals at power densities

    The application of EquiFrame in the analysis of sexual and reproductive health policies by Ivanova et al to a new thematic area, their selection of only some of the Core Concepts of human rights in health service provision and the addition of new vulnerable groups relevant to the purpose of their analysis, are all very welcome developments. We also applaud their application of EquiFrame to policies in countries where it has not previously been used, along with their use of interviews with policy-makers to produce a deeper understanding of policy processes. We argue that clear justification for the inclusion of additional, or replacement of some exiting vulnerable groups within EquiFrame should be accompanied by clear definitions of such groups, along with the evidence-base that justifies their classification as a vulnerable or marginalised group. To illustrate the versatility of EquiFrame, we summarise a range of ways in which it has been used across a number of regions; including a brief Case Study of its use to develop the National Health Policy of Malawi. While EquiFrame focuses on policy content, we preview a new policy analysis tool - Equity and Inclusion in Policy Processes (EquIPP) - which assesses the extent of equity and inclusion in broader policy processes. Together, EquiFrame and EquIPP can be used to help governments and civil society ensure that policies are addressing the much stronger emphasis on social inclusion, now apparent in the Sustainable Development Goals (SDGs). © 2016 by Kerman University of Medical Sciences.

  11. Ozone formation in relation with combustion processes in highly populated urban areas

    2015-07-01

    Full Text Available The complex chain of photochemical reactions is one of the most important tasks in the air quality evaluation, expecially in urban areas. In fact, in this case there are high emission levels of NOx and no-methane hydrocarbons by combustion processes such as autovehicular traffic, domestic heating and industrial plants. Ozone is not emitted directly into the atmosphere but it is formed from a complex series of reactions between emitted nitrogen oxides (NOx and reactive organic compounds (ROC. The high ozone concentrations, which occur during photochemical episodes, are usually accompanied by elevated concentrations of other photochemical oxidants such as nitric acid (HNO3, peroxyacylnitrates (PANs, hydrogen peroxide (H2O2, etc. The complex series of these reactions constitutes the most important issue to the degradation of air quality. Further, the NMHCs play a key role in the formation of photochemical air pollution: they are considered as precursors for ozone production at the ground level when the sunlight and nitrogen oxides are present. From a practically point of view defining a quality standard or a limit is substantially correct but it is no sufficient to solve the problem. So it should become necessary to acquire knowledge on the different formation mechanisms of the photochemical pollution phenomena. In this paper there will be shown the results of a long-term study performed in Rome for evaluating the ozone formation in relationship with the autovehicular traffic density.

    Context. One of the key questions of the star formation problem is whether brown dwarfs (BDs) form in the manner of stars directly from the gravitational collapse of a molecular cloud core (star-like) or whether BDs and some very low-mass stars (VLMSs) constitute a separate population that forms alongside stars comparable to the population of planets, for example through circumstellar disk (peripheral) fragmentation. Aims: For young stars in Taurus-Auriga the binary fraction has been shown to be large with little dependence on primary mass above ≈ 0.2 M⊙, while for BDs the binary fraction is population synthesis model in which stellar binary formation is universal with a large binary fraction close to unity. Peripheral objects form separately in circumstellar disks with a distinctive initial mass function (IMF), their own orbital parameter distributions for binaries, and small binary fractions, according to observations and expectations from smoothed particle hydrodynamics (SPH) and grid-based computations. A small amount of dynamical processing of the stellar component was accounted for as appropriate for the low-density Taurus-Auriga embedded clusters. Results: The binary fraction declines strongly in the transition region between star-like and peripheral formation, exhibiting characteristic features. The location of these features and the steepness of this trend depend on the mass limits for star-like and peripheral formation. Such a trend might be unique to low density regions, such as Taurus, which host binary populations that are largely unprocessed dynamically in which the binary fraction is large for stars down to M-dwarfs and small for BDs. Conclusions: The existence of a strong decline in the binary fraction - primary mass diagram will become verifiable in future surveys on BD and VLMS binarity in the Taurus-Auriga star-forming region. The binary fraction - primary mass diagram is a diagnostic of the (non-)continuity of star formation along the mass

    The characteristics of aerosol particles have been poorly evaluated even though haze episodes frequently occur in winter in Northeast China. OC/EC analysis, ion chromatography, and transmission electron microscopy (TEM) were used to investigate the organic carbon (OC) and elemental carbon (EC), and soluble ions in PM 2.5 and the mixing state of individual particles during a severe wintertime haze episode in Northeast China. The organic matter (OM), NH 4 + , SO 4 2- , and NO 3 - concentrations in PM 2.5 were 89.5 μg/m 3 , 24.2 μg/m 3 , 28.1 μg/m 3 , and 32.8 μg/m 3 on the haze days, respectively. TEM observations further showed that over 80% of the haze particles contained primary organic aerosols (POAs). Based on a comparison of the data obtained during the haze formation, we generate the following synthetic model of the process: (1) Stable synoptic meteorological conditions drove the haze formation. (2) The early stage of haze formation (light or moderate haze) was mainly caused by the enrichment of POAs from coal burning for household heating and cooking. (3) High levels of secondary organic aerosols (SOAs), sulfates, and nitrates formation via heterogeneous reactions together with POAs accumulation promoted to the evolution from light or moderate to severe haze. Compared to the severe haze episodes over the North China Plain, the PM 2.5 in Northeast China analyzed in the present study contained similar sulfate, higher SOA, and lower nitrate contents. Our results suggest that most of the POAs and secondary particles were likely related to emissions from coal-burning residential stoves in rural outskirts and small boilers in urban areas. The inefficient burning of coal for household heating and cooking should be monitored during wintertime in Northeast China. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Frozen broccoli can provide a cheaper product, with a longer shelf life and less preparation time than fresh broccoli. We previously showed that several commercially available frozen broccoli products do not retain the ability to generate the cancer-preventative agent sulforaphane. We hypothesized that this was because the necessary hydrolyzing enzyme myrosinase was destroyed during blanching, as part of the processing that frozen broccoli undergoes. This study was carried out to determine a way to overcome loss of hydrolyzing activity. Industrial blanching usually aims to inactivate peroxidase, although lipoxygenase plays a greater role in product degradation during frozen storage of broccoli. Blanching at 86 °C or higher inactivated peroxidase, lipoxygenase, and myrosinase. Blanching at 76 °C inactivated 92% of lipoxygenase activity, whereas there was only an 18% loss in myrosinase-dependent sulforaphane formation. We considered that thawing frozen broccoli might disrupt membrane integrity, allowing myrosinase and glucoraphanin to come into contact. Thawing frozen broccoli for 9 h did not support sulforaphane formation unless an exogenous source of myrosinase was added. Thermal stability studies showed that broccoli root, as a source of myrosinase, was not more heat stable than broccoli floret. Daikon radish root supported some sulforaphane formation even when heated at 125 °C for 10 min, a time and temperature comparable to or greater than microwave cooking. Daikon radish (0.25%) added to frozen broccoli that was then allowed to thaw supported sulforaphane formation without any visual alteration to that of untreated broccoli. © 2013 Institute of Food Technologists®

    In this study, we have investigated the post-adsorption process of ytterbium (Yb) phosphate nano-particle formation by Saccharomyces cerevisiae (yeast). The yeast grown in P-rich medium were exposed to 1.44 × 10-4 mol/L Yb(III) solution for 2-120 h, and 2 months at 25 ± 1 °C at an initial pH of 3, 4, or 5, respectively. Ytterbium concentrations in solutions decreased as a function of exposure time. Field-emission scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (FESEM), transmission electron microscopy (TEM), and synchrotron-based extended X-ray absorption fine structure (EXAFS) analyses revealed that nano-sized blocky Yb phosphate with an amorphous phase formed on the yeast cells surfaces in the solutions with Yb. These nano-sized precipitates that formed on the cell surfaces remained stable even after 2 months of exposure at 25 ± 1 °C around neutral pHs. The EXAFS data revealed that the chemical state of the accumulated Yb on the cell surfaces changed from the adsorption on both phosphate and carboxyl sites at 30 min to Yb phosphate precipitates at 5 days, indicating the Yb-phosphate precipitation as a major post-adsorption process. In addition, the precipitation of Yb phosphate occurred on cell surfaces during 7 days of exposure in Yb-free solution after 2 h of exposure (short-term Yb adsorption) in Yb solution. These results suggest that the released P from the inside of yeast cells reacted with adsorbed Yb on cell surfaces, resulting in the formation of Yb precipitates, even though no P was added to the exposure solution. In an abiotic system, the EXAFS data showed that the speciation of sorbed Yb on the reference materials, carboxymethyl cellulose and Ln resin, did not change even when the Yb was exposed to P solution, without forming Yb phosphate precipitates. This result strongly suggests that the cell surface of the yeast plays an important role in the Yb-phosphate precipitation process, not only as a carrier of the

    Full Text Available The paper describes a new approach to the analysis of the genetic nature of mineral substances in loess deposits. In permafrost under the influence of multiple alternate freezing and thawing in dispersed deposits, quartz particles accumulate the 0.05-0.01 mm fraction, while feldspars are crushed to a coarse fraction of 0.1-0.05 mm. In dispersed sediments formed in temperate and warm climatic zones, the granulometric spectrum of quartz and feldspar has the opposite pattern. The proposed methodology is based on a differential analysis of the distribution of these minerals by the granulometric spectrum. We have proposed two criteria - the coefficient of cryogenic contrast (CCC and the coefficient of distribution of heavy minerals, which allow determination of the degree of participation of cryogenic processes in the formation of loess sediments and processes of aeolian or water sedimentation.

    This work is a study of the kinetics of formation and of the heat resistance of electrospark coatings based on the composite TiB 2 -Mo with varying molybdenum content. In the process of electrospark alloying they measured the specific erosion of the anode and the increase in weight of the cathode with an accuracy not worse than 5%. Electrospark coatings of TiB 2 -Mo on steel 45 are marked by improved scaling resistance at temperatures above 900 C. Their scaling resistance and also the effectiveness of the process of electrospark alloying increase with increasing content of the phase B-MoB in the coating because molybdenum borate forms during its high-temperature oxidation.

    Full Text Available Mango nectar is a commercially familiar and preferred product. The traditional processing of mango nectar has been by thermal processing which resulted in the alteration of the flavour of the product due to the effect of high temperature. The thermal processing of the nectar also resulted in the production of byproducts of non-enzymatic browning such as 5- hydroxy methyl furfural (HMF. These process induced effects, affect both the nutritive and sensory attributes of the fruit product, making it less preferable. With the growing interest and awareness about the benefits of alternative non-thermal technologies, such as pulsed electric field (PEF, the present work was proposed to use PEF to minimize the loss of volatiles and formation of HMF. The study involves thermal (96 ºC for 300 s and 600 s, PEF (24 µs, 120 Hz and 38 kV/cm and combination processing (PEF + Thermal (96 ºC for 90 s of mango nectar. The effect of these treatments on the volatile composition of mango nectar has been analysed using GC-MS technique. The reduction in the volatile compounds was significant (p 0.05 different from unprocessed sample, proving the fresh-like character of the product.

    The primary astrophysical source of the rare-earth elements is the rapid neutron capture process ( r process). The rare-earth peak that is seen in the solar r -process residuals has been proposed to originate as a pile-up of nuclei during the end of the r process. We introduce a new method utilizing Monte Carlo studies of nuclear masses in the rare-earth region, that includes self-consistently adjusting β -decay rates and neutron capture rates, to find the mass surfaces necessary for the formation of the rare-earth peak. We demonstrate our method with two types of astrophysical scenario, one corresponding to conditions typical of hot winds from core-collapse supernovae and stellar-mass accretion disks, and one corresponding to conditions typical of the ejection of the material from the tidal tails of neutron star mergers. In each type of astrophysical condition, this method successfully locates a region of enhanced stability in the mass surface that is responsible for the rare-earth peak. For each scenario, we find that the change in the mass surface has qualitatively different features, thus future measurements can shed light on the type of environment in which the r process occurred.

  1. Further studies of the spur processes of positronium formation in mixtures of organic liquids

    Jansen, P.; Mogensen, O.E.

    1977-01-01

    To test some predictions of the spur model of positronium (Ps) formation, positron lifetime studies were made of the following binary organic mixtures: (a) carbondisulphide mixtures with n-tetradecane, n-hexane, isooctane, neopentane, and tetramethylsilane (TMS); (b) neopentane mixtures with methanol, ethanol, cyclohexanol, and methylcyclohexane; (c) cis-2-butene/trans-2-butene, and benzene/ethanol. The results were in agreement with the model. A minimum in the Ps yield versus CS 2 concentration, explained as being caused by electron localization on CS 2 at low and delocalization on several CS 2 molecules at higher CS 2 concentration, depended on the electron work function V 0 of the solvent. This minimum was pronounced (shallow or absent) at high (low) V 0 . Solvation of electrons and positrons in alcohol clusters strongly influenced the Ps yield for the neopentane mixtures. The Ps yield was higher in cis- than in trans-2-butene. The Ps formation process in polar liquids is discussed. Experimental facts do not preclude that Ps is also formed by the encounter pair process of fully solvated particles in the positron spur. (Auth.)

    Full text: The Bayer process is used to extract alumina (A I 203) from bauxite ore. The efficiency of the proc severely compromised by the build-up of insoluble species (scale) on the surfaces of mild process equipment, which impedes the material flow through, and heat transfer to, the pr streams [1]. In precipitation areas operating at 60-8 C gibbsite, AI(OHh, scales predominate the spent liquor heaters which typically operate at 150-250 0 C, sodalite and cancrinite-type s aluminosilicate scales are formed (1). An improved understanding of the scale formation mechanism may lead to the development of a practical and economic method for scale prevention. Characterisation of the structure, composition and crystallographic orientation of phases present early stages of formation is crucial for this understanding, making x-ray and neutron diffraction important analytical techniques. In situ synchrotron x-ray diffraction experiments were performed Australian Synchrotron during AI(OHh deposition on mild steel substrates using a purpose built stainless steel flow cell (3). The high resolution data enabled identification of three polymors AI(OH)3 (gibbsite, bayerite and nordtsrandite) in the deposited material, each displaying ori growth along (001). Additional in situ synchrotron XRD experiments, where AI(OH)3 precipitatiol 'seeded' with various iron oxides and oxyhydroxides, have also been performed and some ' results will be discussed. Similar neutron diffraction experiments on Wombat are planned investigations of seeded aluminosilicate precipitation at 150-250 0 C using an Inconel hydrothermal cell.

  3. Neural Correlates of Auditory Processing, Learning and Memory Formation in Songbirds

    Pinaud, R.; Terleph, T. A.; Wynne, R. D.; Tremere, L. A.

    Songbirds have emerged as powerful experimental models for the study of auditory processing of complex natural communication signals. Intact hearing is necessary for several behaviors in developing and adult animals including vocal learning, territorial defense, mate selection and individual recognition. These behaviors are thought to require the processing, discrimination and memorization of songs. Although much is known about the brain circuits that participate in sensorimotor (auditory-vocal) integration, especially the ``song-control" system, less is known about the anatomical and functional organization of central auditory pathways. Here we discuss findings associated with a telencephalic auditory area known as the caudomedial nidopallium (NCM). NCM has attracted significant interest as it exhibits functional properties that may support higher order auditory functions such as stimulus discrimination and the formation of auditory memories. NCM neurons are vigorously dr iven by auditory stimuli. Interestingly, these responses are selective to conspecific, relative to heterospecific songs and artificial stimuli. In addition, forms of experience-dependent plasticity occur in NCM and are song-specific. Finally, recent experiments employing high-throughput quantitative proteomics suggest that complex protein regulatory pathways are engaged in NCM as a result of auditory experience. These molecular cascades are likely central to experience-associated plasticity of NCM circuitry and may be part of a network of calcium-driven molecular events that support the formation of auditory memory traces.

  4. Utilizing Stable Isotopes and Isotopic Anomalies to Study Early Solar System Formation Processes

    Chondritic meteorites contain a diversity of particle components, i.e., chondrules and calcium-, aluminum-rich refractory inclusions (CAIs), that have survived since the formation of the Solar System. The chemical and isotopic compositions of these materials provide a record of the conditions present in the protoplanetary disk where they formed and can aid our understanding of the processes and reservoirs in which solids formed in the solar nebula, an important step leading to the accretion of planetesimals. Isotopic anomalies associated with nucleosynthetic processes are observed in these discrete materials, and can be compared to astronomical observations and astrophysical formation models of stars and more recently proplyds. The existence and size of these isotopic anomalies are typically thought to reflect a significant state of isotopic heterogeneity in the earliest Solar System, likely left over from molecular cloud heterogeneities on the grain scale, but some could also be due to late stellar injection. The homogenization of these isotopic anomalies towards planetary values can be used to track the efficiency and timescales of disk wide mixing,

    In the Transdanubian Range (Hungary), dolostone and dolomitic limestone appear in a number of sedimentary successions formed from the Late Permian to the Late Triassic in various depositional settings and under various diagenetic conditions, whereas only a negligible amount of dolomite was detected in the post-Triassic formations. Seven dolomite-bearing units representing ramp, small and large carbonate platforms, and intraplatform basin settings are presented in this synopsis. In most cases, multi-stage and polygenetic dolomitization was inferred. The main mass of the dolostones was formed via near-surface diagenetic processes, which were commonly preceded by the formation of synsedimentary dolomite. Accordingly, surficial conditions that prevailed during sediment deposition controlled the dolomite-forming processes and thus the lateral extension and the time span of dolomitization. The area of episodic subaerial exposure was a critical controlling factor of the lateral extension of the near-surface dolomite genesis, whereas its temporal extension was mostly governed by climate. Burial diagenesis usually resulted in only moderate dolomitization, either in connection with compactional fluid flow or via thermal convection. The Triassic fault zones provided conduits for fluid flow that led to both replacive dolomitization and dolomite cement precipitation. In the Late Triassic extensional basins, synsedimentary fault-controlled dolomitization of basinal deposits was reconstructed.

    Epithelial (E)-cadherin-mediated cell−cell junctions play important roles in the development and maintenance of tissue structure in multicellular organisms. E-cadherin adhesion is thus a key element of the cellular microenvironment that provides both mechanical and biochemical signaling inputs. Here, we report in vitro reconstitution of junction-like structures between native E-cadherin in living cells and the extracellular domain of E-cadherin (E-cad-ECD) in a supported membrane. Junction formation in this hybrid live cell-supported membrane configuration requires both active processes within the living cell and a supported membrane with low E-cad-ECD mobility. The hybrid junctions recruit α-catenin and exhibit remodeled cortical actin. Observations suggest that the initial stages of junction formation in this hybrid system depend on the trans but not the cis interactions between E-cadherin molecules, and proceed via a nucleation process in which protrusion and retraction of filopodia play a key role.

    There is limited research on the use of evidence to inform policy-making in the Pacific. This study aims to identify and describe factors that facilitate or limit the use of evidence in food-related policy-making in the Health and Agriculture Ministries in Fiji. Semi-structured face-to-face interviews were conducted with selected policy-makers in two government ministries that were instrumental in the development of food-related policies in Fiji designed to prevent Non-Communicable Diseases (NCDs). Snowball sampling was used to recruit, as key informants, senior policy-makers in management positions such as national advisors and directors who were based at either the national headquarters or equivalent. Interviewees were asked about their experiences in developing food-related or other policies, barriers or facilitators encountered in the policy development and implementation process and the use of evidence. Each interview lasted approximately 45-60 minutes, and was conducted in English. Audio-recorded interviews were transcribed, thematically coded and analyzed using N-Vivo 8.0 software. Thirty-one policy-makers from the Ministry of Health and Medical Services (MoHMS n = 18) and the Ministry of Agriculture (MoA n = 13) in Fiji participated in the study. Whilst evidence is sometimes used in food-related policy-making in both the Health and Agriculture Ministries (including formal evidence such as published research and informal evidence such as personal experiences and opinions), it is not yet embedded as an essential part of the process. Participants indicated that a lack of resources, poor technical support in terms of training, the absence of clear strategies for improving competent use of evidence, procedures regarding engagement with other stakeholders across sectors, varying support from senior managers and limited consultation across sectors were barriers to evidence use. The willingness of organizations to create a culture of using evidence was

    Relative to the amount of global attention and media coverage since the first and second Gulf Wars, very little has been published in the health services research literature regarding the state of health services in Iraq, and particularly on the semi-autonomous region of Kurdistan. Building on findings from a field visit, this paper describes the state of health services in Kurdistan, analyzes their underlying governance structures and policy processes, and their overall impact on the quality, accessibility and cost of the health system, while stressing the importance of reinvesting in public health and community-based primary care. Very little validated, research-based data exists relating to the state of population health and health services in Kurdistan. What little evidence exists, points to a region experiencing an epidemiological polarization, with different segments of the population experiencing rapidly-diverging rates of morbidity and mortality related to different etiological patterns of communicable, non-communicable, acute and chronic illness and disease. Simply put, the rural poor suffer from malnutrition and cholera, while the urban middle and upper classes deal with issues of obesity and Type 2 diabetes. The inequity is exacerbated by a poorly governed, fragmented, unregulated, specialized and heavily privatized system, that not only leads to poor quality of care and catastrophic health expenditures, but also threatens the economic and political stability of the region. There is an urgent need to revisit and clearly define the core values and goals of a future health system, and to develop an inclusive governance and policy framework for change, towards a more equitable and effective primary care-based health system, with attention to broader social determinants of health and salutogenesis.

    The effect of some variables in the (Th, U) O 2 sintering process and solid solution formation was studied. ThO 2 , U 3 O 8 and UO 2 powder were prepared. The ThO 2 powders were obtained by calcination of thorium at 500 and 750 deg C; the U 3 O 8 powders were derived from the calcination of ADU at 660 and 750 deg C; the UO 2 powder were prepared from ADU and from ATCU. The different characteristics of these materials were determined by measurements of surface area, by scanning electron microscopy, tap density tests, X-ray diffractometry and by measurements of the O/U ratios. The oxide mixtures were chosen in order to produce a final composition with 10 w/o of UO 2 . A mixture of thorium oxalate and ADU was also prepared by calcining these salts in air at 700 deg C, in order to obtain certain amount of solid solution prior to sintering. The sintering operations were developed in an argon atmosphere at temperatures between 1400 and 1700 deg C, during interval varying from 1 to 4 hours. The effect of the mixture characteristics on the sintering process and solid solution formation were studied considering the results of densification, microstructure development and X-ray diffractometry. The ThO 2 powder characteristics have a main effect on the mixtures compactability and sinterability, the higher calcining temperatures increasing the green density, but decreasing the final density of the sintered pellets. In the sintering of mixtures containing U 3 O 3 , this oxide is reduced to UO 2 and it is possible to obtain pellets with density and microstructures similar to those produced from mixtures containing UO 2 . But if oxygen in excess is present during sintering, the process is affected, occurring exaggerated grain growth. The densification results were related to the Coble's kinetics equation for second stage of sintering, valid for bulk diffusion, grain boundary acting as vacancy sinks. The sintering activation energy is independent from the powder starting

    Advanced nuclear fuel cycles rely on successful chemical separation of various elements in the used fuel. Numerous solvent extraction (SX) processes have been developed for the recovery and purification of metal ions from this used material. However, the predictability of process operations has been challenged by the lack of a fundamental understanding of the chemical interactions in several of these separation systems. For example, gaps in the thermodynamic description of the mechanism and the complexes formed will make predictions very challenging. Recent studies of certain extraction systems under development and a number of more established SX processes have suggested that aggregate formation in the organic phase results in a transformation of its selectivity and efficiency. Aggregation phenomena have consistently been interfering in SX process development, and have, over the years, become synonymous with an undesirable effect that must be prevented. This multiyear, multicollaborative research effort was carried out to study solvation and self-organization in non-aqueous solutions at conditions promoting aggregation phenomena. Our approach to this challenging topic was to investigate extraction systems comprising more than one extraction reagent where synergy of the metal ion could be observed. These systems were probed for the existence of stable microemulsions in the organic phase, and a number of high-end characterization tools were employed to elucidate the role of the aggregates in metal ion extraction. The ultimate goal was to find connections between synergy of metal ion extraction and reverse micellar formation. Our main accomplishment for this project was the expansion of the understanding of metal ion complexation in the extraction system combining tributyl phosphate (TBP) and dibutyl phosphoric acid (HDBP). We have found that for this system no direct correlation exists for the metal ion extraction and the formation of aggregates, meaning that the

Our main accomplishment for this project was the expansion of the understanding of metal ion complexation in the extraction system combining tributyl phosphate (TBP) and dibutyl phosphoric acid (HDBP). We have found that for this system no direct correlation exists for the metal ion extraction and the formation of aggregates, meaning that the

    Authigenic carbonates are one type of conspicuous manifestation in seep environments that can provide long-term archives of past seepage activity and methane cycling in the oceans. Comprehensive investigations of the microbial community functional structure and their roles in the process of carbonate formation are, however, lacking. In this study, the mineralogical, geochemical, and microbial functional composition were examined in seep carbonate deposits collected from the west slope of the northern section of the Okinawa Trough (OT). The aim of this work was to explore the correspondence between the mineralogical phases and microbial metabolism during carbonate deposit formation. The mineralogical analyses indicated that authigenic carbonate minerals (aragonite, magnesium-rich calcite, dolomite, ankerite and siderite) and iron-bearing minerals (limonite, chlorite, and biotite) were present in these carbonate samples. The carbon and oxygen isotopic values of the carbonate samples varied between -51.1‰ to -4.7‰ and -4.8‰ to 3.7‰, respectively. A negative linear correlation between carbon and oxygen isotopic compositions was found, indicating a mixture of methane-derived diagenetic (low δ13C/high 18O) carbonates and detrital origin (high δ13C/low 18O) carbonates at the OT. GeoChip analyses suggested that various metabolic activities of microorganisms, including methanogenesis, methane oxidation, sulfite oxidation, sulfate reduction, and metal biotransformations, all occurred during the formation process. On the basis of these findings, the following model for the methane cycle and seep carbonate deposit formation in the sediment column at the OT is proposed: (1) in the upper oxidizing zone, aerobic methane oxidation was the main way of methane consumption; (2) in the sulfate methane transition zone, sulfate-dependent AOM (anaerobic oxidation of methane) consumes methane, and authigenic minerals such as aragonite, magnesium-calcite, and sulfide minerals

    Ankylosing spondylitis (AS) is an immune-mediated arthritis particularly targeting the spine and pelvis and is characterised by inflammation, osteoproliferation and frequently ankylosis. Current treatments that predominately target inflammatory pathways have disappointing efficacy in slowing disease progression. Thus, a better understanding of the causal association and pathological progression from inflammation to bone formation, particularly whether inflammation directly initiates osteoproliferation, is required. The proteoglycan-induced spondylitis (PGISp) mouse model of AS was used to histopathologically map the progressive axial disease events, assess molecular changes during disease progression and define disease progression using unbiased clustering of semi-quantitative histology. PGISp mice were followed over a 24-week time course. Spinal disease was assessed using a novel semi-quantitative histological scoring system that independently evaluated the breadth of pathological features associated with PGISp axial disease, including inflammation, joint destruction and excessive tissue formation (osteoproliferation). Matrix components were identified using immunohistochemistry. Disease initiated with inflammation at the periphery of the intervertebral disc (IVD) adjacent to the longitudinal ligament, reminiscent of enthesitis, and was associated with upregulated tumor necrosis factor and metalloproteinases. After a lag phase, established inflammation was temporospatially associated with destruction of IVDs, cartilage and bone. At later time points, advanced disease was characterised by substantially reduced inflammation, excessive tissue formation and ectopic chondrocyte expansion. These distinct features differentiated affected mice into early, intermediate and advanced disease stages. Excessive tissue formation was observed in vertebral joints only if the IVD was destroyed as a consequence of the early inflammation. Ectopic excessive tissue was predominantly

    Biologically mediated processes have been regarded and developed as an alternative approach to traditional ground improvement techniques. Denitrification has been investigated as a potential ground improvement process towards liquefaction hazard mitigation. During denitrification, microorganisms reduce nitrate to dinitrogen gas and facilitate calcium carbonate precipitation as a by-product under adequate environmental conditions. The formation of dinitrogen gas desaturates soils and allows for potential pore pressure dampening during earthquake events. While, precipitation of calcium carbonate can improve the mechanical properties by filling the voids and cementing soil particles. As a result of small changes in gas and mineral phases, the mechanical properties of soils can be significantly affected. Prior research has primarily focused on quantitative analysis of overall residual calcium carbonate mineral and biogenic gas products in lab-scale porous media. However, the distribution of these products at the pore-scale has not been well-investigated. In this research, denitrification is activated in a microfluidic chip simulating a homogenous pore structure. The denitrification process is monitored by sequential image capture, where gas and mineral phase changes are evaluated by image processing. Analysis of these images correspond with previous findings, which demonstrate that biogenic gas behaviour at the pore scale is affected by the balance between reaction, diffusion, and convection rates.

    On-board production of hydrogen for fuel cells for automotive applications is a challenging developmental task. The fuel processor must show long term durability and under challenging conditions. Fuel processor catalysts in automotive fuel processors will be exposed to large thermal variations, vibrations, exposure to uncontrolled ambient conditions, and various impurities from ambient air and from fuel. For the commercialization of fuel processors, the delineation of effects on catalyst activity and durability are required. We are studying fuels and fuel constituent effects on the fuel processor system as part of the DOE Fuel Cells for Transportation program. Pure fuel components are tested to delineate the fuel component effect on the fuel processor and fuel processor catalysts. Component blends are used to simulate ''real fuels'', with various fuel mixtures being examined such as reformulated gasoline and naptha. The aliphatic, napthenic, olefin and aromatic content are simulated to represent the chemical kinetics of possible detrimental reactions, such as carbon formation, during fuel testing. Testing has examined the fuel processing performance of different fuel components to help elucidate the fuel constituent effects on fuel processing performance and upon catalyst durability. Testing has been conducted with vapor fuels, including natural gas and pure methane. The testing of pure methane and comparable testing with natural gas (97% methane) have shown some measurable differences in performance in the fuel processor. Major gasoline fuel constituents, such as aliphatic compounds, napthanes, and aromatics have been compared for their effect on the fuel processing performance. Experiments have been conducted using high-purity compounds to observe the fuel processing properties of the individual components and to document individual fuel component performance. The relative carbon formation of different fuel constituents have been measured by

    2007-02-01

    In this study, the formation of extracellular polymeric substances (EPS) and surface characteristics of an acidogenic sludge in anaerobic H(2)-producing process was investigated. Results show that carbohydrates, proteins, and humic substances were the dominant components in bound EPS (BEPS), while in soluble EPS (SEPS), carbohydrates were the main component. The total content of BEPS initially increased but then kept almost unchanged during fermentation from 25 to 35 h; after that, it slightly decreased. The total content of SEPS increased to 172.5 +/- 0.05 mg C g(-1) volatile suspended solid with the time that increased to 23.5 h, and then rapidly decreased until 43 h; thereafter, it kept almost unchanged. The SEPS had good correlations with the specific H(2) production rate, substrate degradation rate, and specific aqueous products formation rate, but the BEPS seemed to have no such correlations with these specific rates. Results also confirm that part of EPS could be utilized by the H(2)-producing sludge. As the substrate was in short supply, the EPS would be hydrolyzed to sever as carbon and energy source.

    Electrospun pyrene (Py)/polystyrene/tetrabutylammonium hexafluorophosphate (TBAPF6) thin films can provide high-sensitivity and high-selectivity detection of nitro-aromatic explosives through fluorescence quenching of the Py excimers. However, we have found that the formation of Py excimers in Py/PS/TBAPF6 thin films depends greatly on the manufacturing processes. Our results indicate that high solvent vapor pressure promotes the Py excimer fluorescence, while high temperature (around or greater than Tg of the PS) has an opposite effect in absence of solvent - reducing the Py excimer fluorescence. Moreover, we have found that salts structure such as cation chain length, anion strength can significantly affect the formation of Py excimer both in solution and solid state, presumably due to self-aggregation of the salts and electrostatic interactions between ions and pyrene excimer. 13C-NMR and steady-state fluorescence result indicate that the salt induces peak shift to the downfield in the spectra and quenches the Py excimer intensity drastically.

    Galaxies are found to obey scaling relations between a number of observables. These relations follow different trends at the low- and high-mass ends. The processes driving the curvature of scaling relations remain uncertain. In this Letter, we focus on the specific family of early-type galaxies, deriving the star formation histories of a complete sample of visually classified galaxies from Sloan Digital Sky Survey DR7 over the redshift range 0.01 < z < 0.025, covering a stellar mass interval from 10{sup 9} to 3 Multiplication-Sign 10{sup 11} M{sub Sun }. Our sample features the characteristic 'knee' in the surface brightness versus mass distribution at M{sub *} {approx} 3 Multiplication-Sign 10{sup 10} M{sub Sun} . We find a clear difference between the age and metallicity distributions of the stellar populations above and beyond this knee, which suggests a sudden transition from a constant, highly efficient mode of star formation in high-mass galaxies, gradually decreasing toward the low-mass end of the sample. At fixed mass, our early-type sample is more efficient in building up the stellar content at early times in comparison to the general population of galaxies, with half of the stars already in place by redshift z {approx} 2 for all masses. The metallicity-age trend in low-mass galaxies is not compatible with infall of metal-poor gas, suggesting instead an outflow-driven relation.

    The lost foam casting process utilizes injection modeled polymeric foam patterns for the production of metallic components. Foamed polymer patterns of the desired shape are coated with a water-based refractory slurry, dried and embedded in unbonded sand. Molten metal is poured directly on the coated polymer. The polymer undergoes thermal degradation and is gradually replaced by the liquid metal to yield the casting after solidification. Expanded polystyrene (EPS) is the most common pattern material used in commercial practice. The use of EPS patterns with ferrous castings may result in the formation of carbonaceous defects in the casting. Consequently, polymethylmethacrylate (PMMA) and copolymers of EPS and PMMA have been developed for ferrous castings. The thermal degradation of the foamed pattern results in the formation of gaseous degradation products and of a partially depolymerized viscous residue. The fraction of viscous residue increased with temperature and is essentially constant above about 650 C. During the filling of EPS patterns, nearly 60% of the polymer is converted to the viscous residue and 40% is transformed to gaseous products. In the case of PMM, almost 60% of the polymer undergoing degradation at the metal front is transformed to gaseous products. The melt flow velocity during the filling of the mold generally increases with temperature.

    The effects of pasteurization, boiling, microwaving, processing and storage of milk and some locally produced dairy products on cholesterol contents and cholesterol oxides formation were studied and evaluated. The 7-ketocholesterol were not detected (ND) in all raw milk samples. On the contrary, heating of milk led to formation of cholesterol oxidation products (COPs), mostly, 7- ketocholesterol in different quantities. No significant effect of heating of milk on cholesterol level was observed with the exception of the ultra-high temperature (UHT) milk prepared from milk powder heated at 140 + - 1.0 degree C for 4 sec showed the highest value of 7-ketocholesterol (80.97 mgg-1), followed by microwave heated milk for 5 min (31.29 mgg-1), whereas the lowest value was in milk pasteurized at 85 + - 1.0 degree C for 16 sec (3.125 mgg-1). Commercial storage showed no significant effect on cholesterol and 7-ketocholestrol but lowered cholesterol concentration and increased 7-ketocholestrol level of UHT reconstituted milk. Cholesterol content of both yogurt and labaneh strained by centrifugal separator showed significant decrease while 7-ketochostrol level was increased significantly with refrigerated storage. The findings are discussed in the context with the results of previous similar studies. (author)

    Listeria monocytogenes can colonize in the food processing environment and thus pose a greater risk of cross-contamination to food. One of the proposed mechanisms that facilitates such colonization is biofilm formation. As part of a biofilm, it is hypothesized that L. monocytogenes can survive sanitization procedures. In addition, biofilms are difficult to remove and may require additional physical and chemical mechanisms to reduce their presence and occurrence. The initial stage of biofilm formation is attachment to surfaces, and therefore it is important to be able to determine the ability of L. monocytogenes strains to attach to various inert surfaces. In this chapter, methods to study bacterial attachment to surfaces are described. Attachment is commonly induced by bringing planktonic cells into contact with plastic, glass, or stainless steel surfaces with or without food residues ("soil") in batch or continuous (e.g., with constant flow of nutrients) culture. Measurement of biofilm formed is carried out by detaching cells (with various mechanical methods) and measuring the viable counts or by measuring the total attached biomass. Resistance of biofilms to sanitizers is commonly carried out by exposure of the whole model surface bearing the attached cells to a solution of sanitizer, followed by measuring the survivors as described above.

    The authors report on the first investigation of the variations in the plasma parameters in the formation process of the honeycomb pattern in a dielectric barrier discharge by optical emission spectrum in argon and air mixture. The discharge undergoes hexagonal lattice, concentric spot-ring pattern and honeycomb pattern with the applied voltage increasing. The molecular vibration temperature, electron excitation temperature and electronic density of the three kinds of patterns were investigated by the emission spectra of nitrogen band of second positive system (C3pi(u) --> B3 pi(g)), the relative intensity ratio method of spectral lines of Ar I 763.51 nm (2P(6) --> 1S(5)) and Ar I 772.42 nm (2P(2) -->1S(3)) and the broadening of spectral line 696.5 nm respectively. It was found that the molecular vibration temperature and electron excitation temperature of the honeycomb pattern are higher than those of the hexagonal lattice, but the electron density of the former is lower than that of the latter. The discharge powers of the patterns were also measured with the capacitance method. The discharge power of the honeycomb pattern is much higher than that of the hexagonal lattice. These results are of great importance to the formation mechanism of the patterns in dielectric barrier discharge.

    Programmed cell death (PCD), a topic of abiding interest, remodels plants at the cell, tissue, and organ levels involving various developmental processes of plants. The aim of this study is to provide a morphological characterization of evidence of PCD involvement in the laticiferous canal formation in fruit of Decaisnea fargesii. Several ultrastructural features of PCD have been observed including disintegration of vacuole and plasma membranes, cell wall degeneration, degenerated cytoplasm, abundant membrane structures and flocculent material, mitochondria and misshapen nuclei coupled with degraded plastids in vacuoles, and nuclei enveloped by rubber granule. In D. fargesii, the nuclei of the secretory epidermal cells become TUNEL-positive from the sunken stage to the late expanding stage, then DAPI-negative during the mature stage, indicating an early event of deoxyribonucleic acid (DNA) cleavage and a late event of complete DNA degeneration. Gel electrophoresis indicates that DNA cleavage is random and does not result in the laddering pattern indicating multiples of internucleosomal units. During the PCD of secretory epidermal cells, the rubber granules continue to be synthesized and accumulated in the secretory epidermal cells despite nuclear degradation. The PCD's role in laticiferous canal formation suggests that PCD may play important roles in gland development of plants.

    Full Text Available The period of post-socialist transition in Serbia brings more complex actors environment compared to socialistic period, while institutional arrangements are not enough developed to actively involve different groups of actors in spatial policy formulation process. In order to gather certain knowledge as guidelines for redefining institutional practices in Serbia, institutional framework of Serbia was compared in this paper with institutional framework of three developed European countries, especially in relation to the roles of public, private and civil sector in spatial policy formulation process. The European countries selected for the analysis are United Kingdom, Netherlands and Germany because of diverse national administrative traditions, so different institutional arrangements could be researched. By comparing institutional framework in Serbia with the ones in developed European countries following questions are researched: which actors are missing in Serbia, what are the ways institutional arrangements for different groups inclusion into spatial policy formulation process are formed, what are the differences between the roles of certain groups of actors in decision-making process. Current roles of actors in spatial policy formulation process in Serbia are reviewed and possible directions for public, private and civil sector role redefinition in Serbia are discussed in accordance with experiences of developed European countries.

    Recent technology advances in the processing of polymeric multilayers has made possible the production of an all polymeric cold mirror reflector via coextrusion processing. The simultaneous formation of up to 5200 alternating layers of optically dissimilar polymers allows the continuous extrusion of a self supporting cold mirror at high linear speeds and widths of over 0.6 m (2 ft). The material can be post formed into shallow 3-dimensional reflector shapes, given proper attention to the initial film optical properties, the final part geometry, and forming considerations. The self supporting nature of the film allows it to be wound on rolls and stored for later part fabrication. Reflectance of 95-99% over the visible wavelengths has been achieved with commercially available polymers. The polymers used have high transmission in the near infrared region of 700-2000 nm, and sharp cut- on and cut-offs have been achieved. Uniformity of optical properties across the surface of the film will be discussed, as will thickness, angle of incidence, and temperature effects. The large area capability of this material may make possible applications for heat/light separation not previously viable due to deposition chamber size limitations or the high cost per area of conventional deposition technologies. Scale up of the process to much larger widths is feasible and will be discussed. Prototyped parts and potential applications of this new material will also be covered.

    2014-09-01

    Full Text Available Flavor is an important factor in the acceptance of food. Flavor of poultry meat is naturally formed through a specific process of heating, where various chemical reactions complex occurred among nonvolatile precursors in fatty tissue or in lean tissue. The main flavor in the form of volatile and nonvolatile components play a major influence on the acceptance of various processed meat, especially the taste. Removal of sulfur components decreases meat flavor (meaty, while removal of carbonyl compounds decrease the specific flavor and increases common flavor of the meat. Poultry meat has a fairly high fat content that easily generates lipid oxidation. Lipid oxidation in poultry meat is a sign that the meat was damaged and caused off odor. Addition of antioxidants in the diet can inhibit lipid oxidation in the meat. Lipids interaction with proteins and carbohydrates is unavoidable during the thermal processing of food, causing the appearance of volatile components. The main reaction in meat flavor formation mechanism is Maillard reaction followed by Stecker reaction and degradation of lipids and thiamine. They involve in the reaction between carbonyl and amine components to form flavor compounds, which enhance the flavor of poultry meat.

    Radiation processing of beans, which are a major source of dietary protein in Brazil, is a valuable alternative to chemical fumigation to combat postharvest losses due to insect infestation. To ensure free consumer choice, irradiated food will be labeled as such, and to enforce labeling, analytical methods to detect the irradiation treatment in the food product itself are desirable. In two varieties of Brazilian beans, Carioca and Macacar beans, the radiolytic formation of hydrocarbons formed after alpha and beta cleavage, with regard to the carbonyl group in triglycerides, have been studied. Using gas chromatographic analysis of these radiolytic hydrocarbons, different yields per precursor fatty acid are observed for the two types of beans. However, the typical degradation pattern allows the identification of the irradiation treatment in both bean varieties, even after 6 months of storage

    2014-01-01

    This study examined the effects of in-session interpersonal process and pre-therapy interpersonal problems on session-one alliance formation for 32 clients who received short-term experiential therapy for depression. Interpersonal behavior measured by the Structural Analysis of Social Behavior, as well as clients' pre-therapy reports of interpersonal problems significantly related to session-one alliance scores. Greater client disclosure independently predicted a stronger session-one bond with the therapist. Both greater client disclosure (positively) and pre-therapy Social Inhibition (negatively) independently predicted early goal agreement. Findings suggest that client disclosure is a marker of early engagement in experiential therapy, as well as support this model's mandate to form interpersonally safe therapeutic environments from the first moments of therapy.

    In this paper, we present the possibility of liquid delivery using fabricated hollow silicon dioxide microneedles of approximately 2 µm in diameter. As a fundamental study, the water-droplet formation and ejection process was examined via dynamic observations during water ejection tests and computational fluid dynamics (CFD) analysis. The experimental results indicated that fluid flow in a microneedle follows the Hagen-Poiseuille law, i.e., the flow rate is approximately directly proportional to the fourth power of the inner diameter. Moreover, the ejection pressure and maximum droplet curvature obtained using the proposed microfluid ejection model were in good agreement with the experimental results. The resulting ejection pressure is equal to the theoretical pressure difference of a spherical droplet, which is determined using the Young-Laplace equation. The maximum curvature of a droplet formed at the tip of a microneedle can be estimated on the basis of the contact angle theory expressed by the Young equation.

    Full Text Available In a highly industrialized and media-saturated country like Switzerland children of all origins are strong multimedia users. Switzerland has one of the highest proportions of migrants in Europe: About 20,5 percent of the population are of migrant origin. So far, media research in Switzerland focussing on children and young people has paid no special attention to the extent the cultural background may influence the media use, i.e. whether the media play a specific function in processes of identity-formation for these children. More detailed and qualified information on this topic is of interest when faced with the fact that the social background is still one of the key determinants of a successful career in our society. This paper will discuss first findings of a project focussing on the impact of the cultural background on the media use of children with a migrant background in Switzerland.

    This study investigated the effects of religious education on student religious identity over and above parent religiosity by examining student perceptions of two aspects of teacher functioning: teacher caring and teacher as role-model. We posited that effects of these variables on students' religious identity are mediated by student perceptions that the school provides a non-alienating religious atmosphere and meaningful religious studies. Participants were 2691 male and female students (grades 9-12) in 152 classes of 25 schools from the Jewish public-religious sector in Israel. Results indicate that in addition to their parents' religiosity, adolescents' perceptions of their teachers as role models and their religious studies as meaningful are important variables affecting their religious identity. Moreover, this research suggests that religious identity formation processes flourish in an educational environment which students perceive as accommodating religious exploration.

    The effect of low-molecular fraction of thymus humoral factor on blood formation in mice irradiated at 4 Gy was studied. It is shown that injection of low-molecular fraction of thymus hymoral factor to irradiated animals affects proliferative processes in spleen and bone marrow, however the degree of the effect depends on the injection scheme of the preparation. Application of mathematical planning methods of the experiment enables to analyze various injection schemes of low-molecular fraction of thymus humoral factor on the investigated indices. The optimal scheme of preparation injection is determined: 1st injection with the dose of 10 mkg/kg following 4 hour after irradiation, 2d injection - with the same dose in 7-21 days

    A new theoretical model based on Boltzmann transport equation for moving displaced atoms is developed for the investigations of main important characteristics of radiation damage production in fusion structural materials. The main characteristics sub-cascades are determined here including the distribution of sub-cascades per PKA, average number of point defects per sub-cascade combining suggested model and NRT approach, sub-cascade's cross-sections and generation rates for both elastic and inelastic processes. On the basis of this developed model the numerical calculations for the main important characteristics of radiation damage production, cascade and sub-cascade formations in different fusion structural materials such as Fe, V, C, Al, Be and W are performed using the neutron energy spectra for fusion reactors: ITER and DEMO. For the comparison of difference in radiation damage production in fusion and fission reactors the additional numerical calculations have been made for neutron energy spectrum in fast atomic reactor HFIR.

  3. Cosmochemical evidence for astrophysical processes during the formation of our solar system.

    Through the laboratory study of ancient solar system materials such as meteorites and comet dust, we can recognize evidence for the same star-formation processes in our own solar system as those that we can observe now through telescopes in nearby star-forming regions. High temperature grains formed in the innermost region of the solar system ended up much farther out in the solar system, not only the asteroid belt but even in the comet accretion region, suggesting a huge and efficient process of mass transport. Bi-polar outflows, turbulent diffusion, and marginal gravitational instability are the likely mechanisms for this transport. The presence of short-lived radionuclides in the early solar system, especially (60)Fe, (26)Al, and (41)Ca, requires a nearby supernova shortly before our solar system was formed, suggesting that the Sun was formed in a massive star-forming region similar to Orion or Carina. Solar system formation may have been "triggered" by ionizing radiation originating from massive O and B stars at the center of an expanding HII bubble, one of which may have later provided the supernova source for the short-lived radionuclides. Alternatively, a supernova shock wave may have simultaneously triggered the collapse and injected the short-lived radionuclides. Because the Sun formed in a region where many other stars were forming more or less contemporaneously, the bi-polar outflows from all such stars enriched the local region in interstellar silicate and oxide dust. This may explain several observed anomalies in the meteorite record: a near absence of detectable (no extreme isotopic properties) presolar silicate grains and a dichotomy in the isotope record between (26)Al and nucleosynthetic (nonradiogenic) anomalies.

    Full Text Available Strategic planning and decision making, nonetheless making energy policies and strategies, is very extensive process and has to follow multiple and often contradictory objectives. During the preparation of the new Slovenian Energy Programme proposal, complete update of the technology and sector oriented bottom up model of Reference Energy and Environmental System of Slovenia (REES-SLO has been done. During the redevelopment of the REES-SLO model trade-off between the simulation and optimisation approach has been done, favouring presentation of relations between controls and their effects rather than the elusive optimality of results which can be misleading for small energy systems. Scenario-based planning was integrated into the MESAP (Modular Energy System Analysis and Planning environment, allowing integration of past, present and planned (calculated data in a comprehensive overall system. Within the paper, the main technical, economic and environmental characteristics of the Slovenian energy system model REES-SLO are described. This paper presents a new approach in modelling relatively small energy systems which goes beyond investment in particular technologies or categories of technology and allows smooth transition to low carbon economy. Presented research work confirms that transition from environment unfriendly fossil fuelled economy to sustainable and climate friendly development requires a new approach, which must be based on excellent knowledge of alternative possibilities of development and especially awareness about new opportunities in exploitation of energy efficiency and renewable energy sources.

    Full Text Available Vibrio cholerae represents a significant threat to human health in developing countries. This pathogen forms biofilms which favors its attachment to surfaces and its survival and transmission by water or food. This work evaluated the in vitro biofilm formation of V. cholerae isolated from clinical and environmental sources on stainless steel of the type used in food processing by using the environmental scanning electron microscopy (ESEM. Results showed no cell adhesion at 4 h and scarce surface colonization at 24 h. Biofilms from the environmental strain were observed at 48 h with high cellular aggregations embedded in Vibrio exopolysaccharide (VPS, while less confluence and VPS production with microcolonies of elongated cells were observed in biofilms produced by the clinical strain. At 96 h the biofilms of the environmental strain were released from the surface leaving coccoid cells and residual structures, whereas biofilms of the clinical strain formed highly organized structures such as channels, mushroom-like and pillars. This is the first study that has shown the in vitro ability of V. cholerae to colonize and form biofilms on stainless steel used in food processing.

    A mathematical model of processes of formation of the working medium in a solid-fuel plasma generator for geophysical pulsed MHD generators is given. The movement of the multiphase, multicomponent medium in the combustion chamber of the plasma generator is examined with consideration of a change in the chemical composition of the gas phase and evolution of the particle sizes of the easily ionized additive, metallic fuel, and metal oxide. As a result of numerical solution of a system of equations for conditions of the combustion chamber of the Pamir MHD generator, the degree of effect of the characteristics of the solid plasma-forming fuel on the electrical conductivity of the working medium was determined. It is shown that losses of conductivity of the working medium are determined mainly by incomplete combustion of the metallic fuel. Processes of combustion of the metal and vaporization of the additive are interrelated, and only combined consideration of the evolution of both ensembles of particles can give a result corresponding to the experiment. 11 refs., 6 figs

    Glyoxal, methylglyoxal, glycolaldehyde, and hydroxyacetone form N-containing and oligomeric compounds during simulated cloud processing with small amines. Using a novel hygroscopicity tandem differential mobility analysis (HTDMA) system that allows varied humidification times, the hygroscopic growth (HG) of each of the resulting products of simulated cloud processing was measured. Continuous water uptake (gradual deliquescence) was observed beginning at ∼ 40% RH for all aldehyde-methylamine products. Particles containing ionic reaction products of either glyoxal or glycine were most hygroscopic, with HG between 1.16 and 1.20 at 80% RH. Longer humidification times (up to 20 min) produced an increase in growth factors for glyoxal-methylamine (19% by vol) and methylglyoxal-methylamine (8% by vol) aerosol, indicating that unusually long equilibration times can be required for HTDMA measurements of such particles. Glyoxal- and methylglyoxal-methylamine aerosol particles shattered in Raman microscopy impact-flow experiments, revealing that the particles were semisolid. Similar experiments on glycolaldehyde- and hydroxyacetone-methylamine aerosol found that the aerosol particles were liquid when dried for glyoxal > glycolaldehyde = hydroxyacetone, likely caused by the speed of oligomer formation in each system.

    Knowledge of the molecular formation mechanism of metal nanoclusters is essential for developing chemistry for accurate control over their synthesis. Herein, the "top-down" synthetic process of monodisperse Au13 nanoclusters via HCl etching of polydisperse Aun clusters (15 ≤ n ≤ 65) is traced by a combination of in situ X-ray/UV-vis absorption spectroscopy and time-dependent mass spectrometry. It is revealed experimentally that the HCl-induced synthesis of Au13 is achieved by accurately controlling the etching process with two distinctive steps, in sharp contrast to the traditional thiol-etching mechanism through release of the Au(i) complex. The first step involves the direct fragmentation of the initial larger Aun clusters into metastable intermediate Au8-Au13 smaller clusters. This is a critical step, which allows for the secondary size-growth step of the intermediates toward the atomically monodisperse Au13 clusters via incorporating the reactive Au(i)-Cl species in the solution. Such a secondary-growth pathway is further confirmed by the successful growth of Au13 through reaction of isolated Au11 clusters with AuClPPh3 in the HCl environment. This work addresses the importance of reaction intermediates in guiding the way towards controllable synthesis of metal nanoclusters.

    Full Text Available Based on the magnetohydrodynamic module of the commercial computational fluid dynamics software FLUENT, a 3-D mathematical model was developed to describe the multi-field coupling phenomenon in the electroslag remelting process. The model predicted value is in good agreement with the experimental measurements. The simulation results show that, during the melt dripping process, the resistance of the electroslag remelting system is decreasing while the current density and velocity, as well as the temperature are increasing gradually. The maximum value of current density, electromagnetic force, and velocity appears when the melt droplet detaches and the quality of large droplets fall into the slag-metal interface. The maximum value of the current density is increased by almost one order of magnitude. The maximum value of the electromagnetic force and velocity increased by 2.5 and 4.7 times, respectively. The maximum value of Joule heating and temperature appears when the droplets fall into the slag-metal interface. The maximum value of the Joule heating and temperature increased for about 174.7% and 26.8%, respectively, when compared with the moment of the melt droplet formation.

  20. Process of defect formation in alkaline halogenides contaminated with Eu2+ induced by non ionizing radiation

    The creation of defects in polluted alkaline halogenides with divalent impurities exposed to ionizing radiation is explained by means of the creation of auto trapped excitons (STE), which can be formed by means of the excitement of the halogen ion or through the trapping of electrons in centers V K taken place during the process of ionization of the halogen ion. The luminescent recombination of the exciton auto trapped produces a characteristic exciton luminescence and the recombination non radiative causes the formation of the Frenkel type defects, even of centers F - H. Experimentally has been demonstrated that the same type of glasses, exposed to radiation non ionizing of the type UV of around 230 nm, they produce defects similar Frenkel. The situation is interesting all time that photons of 230 nm (5.3 eV) they cannot create excitons directly since they are in an energy level of approximately 2.4 inferior eV to the necessary energy for the production of the same ones. In order to investigating the type of process of creation of defects with UV light energy below the energy of the band prohibited in polluted alkaline halogenides with Eu 2+ , mainly looking for experimental information that allows to explain the creation of defects taken place by the radiation non ionizing, one carries out the present work. It was found that, independently of the energy of the radiation used for the excitement, the emission comes from the transition 4f 6 5d(t 2g )-4f 7 ( 8 S 7/2 ) of the ion Eu 2+ characterized by a wide band centered in 420 nm and an additional component in 460 nm of possibly intrinsic origin. It was determined that so much the F centers and F z participate in the thermoluminescent processes and of optically stimulated luminescence, achieving to identify those peaks of Tl strictly associated to the F centers (peak in 470 K for the KCl: Eu 2+ ) and F z (peak in 370 K). Also, by means of a process of selective photo stimulation evidence was obtained that the F

    Broad plasma depletions in the equatorial ionosphere near dawn are region in which the plasma density is reduced by 1-3 orders of magnitude over thousands of kilometers in longitude. This phenomenon is observed repeatedly by the Communication/Navigation Outage Forecasting System (C/NOFS) satellite during deep solar minimum. The plasma flow inside the depletion region can be strongly upward. The possible causal mechanism for the formation of broad plasma depletions is that the broad depletions result from merging of multiple equatorial plasma bubbles. The purpose of this study is to demonstrate the feasibility of the merging mechanism with new observations and simulations. We present C/NOFS observations for two cases. A series of plasma bubbles is first detected by C/NOFS over a longitudinal range of 3300-3800 km around midnight. Each of the individual bubbles has a typical width of approx 100 km in longitude, and the upward ion drift velocity inside the bubbles is 200-400 m/s. The plasma bubbles rotate with the Earth to the dawn sector and become broad plasma depletions. The observations clearly show the evolution from multiple plasma bubbles to broad depletions. Large upward plasma flow occurs inside the depletion region over 3800 km in longitude and exists for approx 5 h. We also present the numerical simulations of bubble merging with the physics-based low-latitude ionospheric model. It is found that two separate plasma bubbles join together and form a single, wider bubble. The simulations show that the merging process of plasma bubbles can indeed occur in incompressible ionospheric plasma. The simulation results support the merging mechanism for the formation of broad plasma depletions.

  4. Effect of pores formation process and oxygen plasma treatment to hydroxyapatite formation on bioactive PEEK prepared by incorporation of precursor of apatite.

    When bioinert substrates with fine-sized pores are immersed in a simulated body fluid (SBF) and the pH value or the temperature is increased, fine particles of calcium phosphate, which the authors denoted as 'precursor of apatite' (PrA), are formed in the pores. By this method, hydroxyapatite formation ability can be provided to various kinds of bioinert materials. In this study, the authors studied fabrication methods of bioactive PEEK by using the above-mentioned process. First, the fine-sized pores were formed on the surface of the PEEK substrate by H 2 SO 4 treatment. Next, to provide hydrophilic property to the PEEK, the surfaces of the PEEK were treated with O 2 plasma. Finally, PrA were formed in the pores by the above-mentioned process, which is denoted as 'Alkaline SBF' treatment, and the bioactive PEEK was obtained. By immersing in SBF with the physiological condition, hydroxyapatite formation was induced on the whole surface of the substrate within 1day. The formation of PrA directly contributed to hydroxyapatite formation ability. By applying the O 2 plasma treatment, hydroxyapatite formation was uniformly performed on the whole surface of the substrate. The H 2 SO 4 treatment contributed to a considerable enhancement of adhesive strength of the formed hydroxyapatite layer formed in SBF because of the increase of surface areas of the substrate. As a comparative study, the sandblasting method was applied as the pores formation process instead of the H 2 SO 4 treatment. Although hydroxyapatite formation was provided also in this case, however, the adhesion of the formed hydroxyapatite layer to the substrate was not sufficient even if the O 2 plasma treatment was conducted. This result indicates that the fine-sized pores should be formed on the whole surface of the substrate uniformly to achieve high adhesive strength of the hydroxyapatite layer. Therefore, it is considered that the H 2 SO 4 treatment before the O 2 plasma and the 'Alkaline SBF' treatment

    Annually laminated (varved) lake sediments represent unique archives in continental areas providing both, precise chronologies and seasonally resolving proxy data. Monitoring of physical, chemical and biological processes influencing lake sediment formation are a suitable approach for detailed proxy understanding of varved sediment records. Lake Tiefer See (NE Germany) indicates deposition of varved sediments today as well as millennia ago (Dräger et al., 2016; Kienel et al., 2013). Therefore, the lake provides the possibility to trace current seasonal layer formation in the lake and to pair these data to climate and lake conditions (Kienel et al., 2016). Lake Tiefer See was formed during the last glaciation and is part of the Klocksin Lake Chain, a subglacial channel system that crosses the Pomeranian terminal moraine. The lake is a mesotrophic hard water lake with a maximum depth of 63 m and a surface area of 0.75 km2. During four consecutive years (2012-2015) the particulate matter deposition was trapped at bi-weekly to monthly resolution at three different water depths (5, 12 and 50 m). The sediment trap material was analysed for sediment flux and organic matter and calcite content. In addition, we monitored limnological parameters (e.g. temperature, pH, conductivity, oxygen content) as well as the meteorological conditions (e.g. temperature, wind speed and direction, precipitation) with a monitoring and climate station installed on the lake. These data describe strength and duration of lake mixing and lake stagnation phases. Our results show distinct seasonal peaks in sediment formation, which correspond to the spring and summer productivity phases comprising of diatom blooms and calcite precipitation. This observation is in line with microfacies results from surface sediment cores. The content of biogenic calcite content decreases in the trapped material with increasing water depth indicating dissolution processes. However, the strength of calcite

    Aqueous phase chemistry might be responsible for the formation of a significant fraction of the organic aerosol (OA) observed in the atmosphere, and could explain some of the discrepancies between OA concentration and properties predicted by models and observed in the environment. Aerosol - fog interaction and its effect on submicron aerosol properties were investigated in the Po Valley (northern Italy) during fall 2011, in the framework of the Supersite project (ARPA Emilia Romagna). Composition and physical properties of submicron aerosol were measured online by a High Resolution- Time of Flight - Aerosol Mass Spectrometer (HR-TOF-AMS), a Soot Photometer - Aerosol Mass Spectrometer (SP-AMS), and a Tandem Differential Mobility Particle Sizer (TDMPS). Organic functional group analysis was performed off-line by Hydrogen - Nuclear Magnetic Resonance (H-NMR) spectrometry and by Fourier Transform Infrared (FTIR) spectrometry. Aerosol absorption, scattering, and total extinction were measured simultaneously with a Particle Soot Absorption Photometer (PSAP), a Nephelometer, and a Cavity Attenuated Phase Shift Spectrometer particle extinction monitor (CAPS PMex), respectively. Water-soluble organic carbon in fog-water was characterized off-line by HR-TOF-AMS. Fourteen distinct fog events were observed. Fog dissipation left behind an aerosol enriched in particles larger than 400 nm, typical of fog and cloud processing, and dominated by secondary species, including ammonium nitrate, ammonium sulfate and oxidized OA (OOA). Source apportionment of OA allowed us to identify OOA as the difference between total OA and primary OA (hydrocarbon like OA and biomass burning OA). The formation of OOA through fog processing is proved by the correlation of OOA concentration with hydroxyl methyl sulfonate signal and by the similarity of OOA spectra with organic mass spectra obtained by re-aerosolization of fog water samples. The oxygen to carbon ratio and the hydrogen to carbon ratio of

    Full Text Available The article is devoted to the problem of genesis and influence on real economic processes of “failures of the state”. The article designates the objective functions inherent in the state the realization of which can increase the efficiency of economic interactions reducing transaction expenses. Besides, the key factors of non-optimal activity of the state as well as actual “failures of the state” are considered. The approaches to the definition of “failures of the state” are analyzed. Taking into account functional approach the author proposes the model definition allowing to separate “failures of the state” from factors and conditions of their emergence. Among the emergence factors of “failures of the state” the author analyzes in detail the key division of economy subjects to net-payers and net-recipients of the income, the fact of distribution of consequences of state regulation to the sectors which are not direct objects of regulation as well as the influence of short-term decisions for long-term prospects are designated. The author also analyzes the range of “failures of the state”, including such as formation of monopolies, tax discouraging, failures of social security, nature of “state business”, derivation of resources and workers from economy, formation of an inequality and calculational (price chaos in economy. The key consequences and volume of the economic damage formed by “failures of the state” are considered, the corresponding quantitative estimates are given. The most important vectors of optimization of activity of the state which provide minimization of “failures of the state” and the related economic damage are designated. According to the author, such vectors include the priority of market self-regulation under the condition of refusal from substitutes in the form of “approach” of public sector to market standards. The minimization of public sector activity aimed at the exclusion of

    In the past two decades, the reaction mechanism of C-C bond formation from either methanol or dimethyl ether (DME) in the methanol-to-hydrocarbons (MTH) process has been a highly controversial issue. Described here is the first observation of a surface methyleneoxy analogue, originating from the surface-activated DME, by in situ solid-state NMR spectroscopy, a species crucial to the first C-C bond formation in the MTH process. New insights into the first C-C bond formation were provided, thus suggesting DME/methanol activation and direct C-C bond formation by an interesting synergetic mechanism, involving C-H bond breakage and C-C bond coupling during the initial methanol reaction within the chemical environment of the zeolite catalyst. © 2017 Wiley-VCH Verlag GmbH & Co.

    The sintering behaviors among SiO2, FeS and Fe3O4 were detected to reveal the formation mechanism of Fe2SiO4. The results indicated that the formation mechanism is divided into five steps: (1) migration of O2- induced by S2- under a reducing atmosphere; (2) formation of Fe3O4-β ; (3) migration of Fe(II) into a ferrite cluster structure to gain oxygen and form Fe3-x O4; (4) Fe(II) invaded the silicon atomic position and released Si(IV); and (5) formation of the stable structure of Fe2SiO4 through chemical diffusion between cations of Fe(II) and Si(IV). These findings can provide theoretical support for controlling the process of the recovery of valuable metals in copper slag through the combined roasting modification-magnetic separation process.

  13. Crossing institutional boundaries: mapping the policy process for improved control of endemic and neglected zoonoses in sub-Saharan Africa.

    2015-07-01

    The recent adoption of the World Health Assembly Resolution 66.12 for neglected tropical diseases (NTDs) in May 2013 is an important turning point for advocacy regarding a number of endemic zoonotic infections, defined by the World Health Organization as the neglected zoonotic diseases (NZDs). In addition to NTD-listed zoonoses such as rabies, echinococcosis (hydatid disease), leishmaniasis, Human African trypanosomiasis (sleeping sickness) and Taenia solium cysticercosis, the NZDs also include important bacterial zoonoses such as anthrax, bovine tuberculosis and brucellosis. To date, analysis of the processes that prioritize, develop and deliver zoonoses control programmes in many low- and middle-income countries is lacking, despite its potential to highlight significant evidence gaps and institutional constraints to the intersectoral approach required for their control. Policy process analysis was conducted via a series of semi-structured interviews with key policy actors within various ministries and institutes in Uganda and Nigeria. The study concluded that despite the rhetoric around 'linear' models of health policy development promoting consultation with a wide range of national stakeholders, the decision-making process for zoonotic disease control appears instead overtly influenced by the external political economy of trending pandemic threats, often overlooking national and regional zoonoses priorities. The inclusion of political systems remains a key factor in the zoonoses analysis matrix, enhancing our understanding of the intersectoral and transdisciplinary approaches required for their control. The authors consider policy process analysis to be a fundamental first step of any attempt to holistically strengthen human and animal health systems in a development context, particularly regarding the promotion of integrated control policies for regionally important zoonoses under the growing One Health movement.

    The importance of using research evidence in decisionmaking at the policy level has been increasingly recognized. However, knowledge brokering to engage researchers and policymakers in government and non-government organizations is challenging. This paper describes and evaluates the knowledge exchange processes employed by the Translational Research on Obesity Prevention in Communities (TROPIC) project that was conducted from July 2009 to April 2012 in Fiji. TROPIC aimed to enhance: the evidence-informed decisionmaking skills of policy developers; and awareness and utilization of local and other obesity-related evidence to develop policies that could potentially improve the nation's food and physical activity environments. The specific research question was: Can a knowledge brokering approach advance evidence-informed policy development to improve eating and physical activity environments in Fiji. The intervention comprised: recruiting organizations and individuals; mapping policy environments; analyzing organizational capacity and support for evidence-informed policymaking (EIPM); developing EIPM skills; and facilitating development of evidence-informed policy briefs. Flexible timetabling of activities was essential to accommodate multiple competing priorities at both individual and organizational levels. Process diaries captured the duration, frequency and type of each interaction and/or activity between the knowledge brokering team and participants or their organizations. Partnerships were formalized with high-level officers in each of the six participating organization. Participants (n = 49) developed EIPM skills (acquire, assess, adapt and apply evidence) through a series of four workshops and applied this knowledge to formulate briefs with ongoing one-to-one support from TROPIC team members. A total of 55% of participants completed the 12 to18 month intervention, and 63% produced one or more briefs (total = 20) that were presented to higher

  18. The influence of knowledge on the public policy making process: the case of renewable energies in Midi Pyrenees

    Behar, L.

    2012-01-01

    Even though energy policy makers were novices when wind power was introduced in the Midi Pyrenees region, the situation had changed when the photovoltaic was implemented. The new challenges policy makers experimented about the wind power and their opponents, the wood energy and the primacy of the wood's industrials, the photovoltaic and the preservation of the agricultural lands, fostered their learning and gradually lead them to change their perception of inherent issues. The coalitions forged between technical experts and policy makers unbind along the progressive empowerment of the formers. Shared between different forms of knowledge, however, the resources needed to implement renewable energies projects cannot be reduced to the technical dimension. Local knowledge and engineering knowledge increasingly compete with expert knowledge. This evolution corresponds to a policy arrangement change. Since the dynamic but also the elements that compose this political system change, a new reality gradually emerges. This whole process will be the main concern of this thesis. We will finally notice that there are some differences between the implementation of these renewable energies among the territories but also among the three forms of renewable energies we analyze. This means that although renewable energy policy are based on interactions between actors' resources, discourse and rules, they also emerge from the action of intermediates actors, and from the characteristic of each territories in which they are implemented.

    been identified within the soil columns because they are fragile; i.e. they are euhedral, unabraded, and unfractured, strongly suggesting in situ formation. Their presence in Antarctic samples is another indication that diagenic processes are active in cold-desert environments. The presence of zeolites, and other clays along with halites, sulfates, carbonates, and hydrates are to be expected within the soil columns on Mars at the Gusev and Isidis Planitia regions. The presence of such water-bearing minerals beneath the surface supplies one of the requirements to support biological activity on Mars.

    This paper reviews of some applications of optical visualization systems to compute the fuel-air mixing process during early stage of mixture formation in Diesel Combustion Engines. A number of studies have contributed to the understanding of fuel air mixing in DI diesel engine. This review has shown that the mixture formation process affects initial flame development. The review also found that injection pressure has a great effect on the mixture formation then the flame development and combustion characteristics. The method of the simulation of real phenomenon of diesel combustion with optical access rapid compression machine is also reviewed and experimental results are presented. The application of these methods to the investigation of diesel sprays highlights mechanisms which govern propagation and distribution of the formation of a combustible fuel-air mixture. A summary of the implementation of constant volume chamber and optical visualization system are shown in the accompanying tables and figures. The visualization of the formation process of diesel spray and its combustion in the diesel combustion chamber of diesel engine has been recognized as one of the best ways to understand the characteristics of the mixture formation.

  1. The Formation of Chimeric Nanomorphologies, as a Reflection of Naturally Occurring Thermodynamic Processes

    Naziris, N.; Demetzos, C.

    2017-11-01

    The self-assembly process of different in nature biomaterials leads to the morphogenesis of various nano-structures, where the individual molecule properties (e.g. hydrophilic-to-hydrophobic balance and elasticity), profoundly affect the intermediate surfaces’ interfacial thermodynamics. Herein, the mixing of a phospholipid and an amphiphilic block copolymer, through the thin-film hydration method, gave different morphologies, among which there were vesicles (i.e. liposomes and polymersomes), micelles and worm-like structures. The formation of such variety of structures is attributed to divergent entropic pathways, which are determined by a number of parameters, such as the lipid:polymer molar ratio and the polymer composition. The developed nanosystems are considered as chimeric/mixed, because of the two different in type biomaterials that compose them. The vesicles also exhibited membrane “irregularities”, which are connected with their biophysical behavior. Nature has “chosen” vesicular forms to be the thermodynamically stable “biological apartments”, in which life was enclosed and additionally, vesicles provided compartmentalized systems, where the intracellular environment was built. Phospholipid properties result in membranes/bilayers that harmonically assimilate other molecules, like proteins and retain their integrity and functionality, while gaining additional features. A cause that alters this relationship might induce changes in the membrane composition and morphology, with respect to lipid rafts/domains, what has been linked with the activation and development of certain human disorders/diseases. The self-assembly of two different biomaterials into various structures that present distinct membrane phenomena is believed to simulate these natural processes.

    The effect of urea on the formation of hydroxyapatite (HAp) was studied by employing the double-step hydrothermal processing of a powder mixture of beta-tricalcium phosphate (β-TCP) and dicalcium phosphate dihydrate (DCPD). Co-existence of urea was found to sustain morphology of HAp crystals in the compacts under an initial concentration of 2 mol dm -3 and less. Homogenous morphology of needle-like crystals was observed on the compacts carbonated owing to decomposition of urea. Carbonate ions (CO 3 2- ) was found to be substituted in both the phosphate and hydroxide sites of HAp lattice. The synthesized HAp was calcium deficient, as it had a Ca/P atomic ratio of 1.62 and the phase was identified as calcium deficient hydroxyapatite (CDHA). The release of CO 3 2- ions from urea during the hydrothermal treatment determined the morphology of the CDHA in the compacts. The usage of urea in the morphological control of carbonate-substituted HAp (CHAp) employing the double-step hydrothermal method is established. Highlights: → Carbonate substituted hydroxyapatite (CHAp) compacts were developed by a new method, namely double-step hydrothermal processing. → CHAp compacts with uniform micromorphology were obtained by using urea as solvent. → Morphology was sustained even at higher concentration of urea, which emphasized the versatility of urea. → Homogenous morphology of CHAp compacts were obtained for higher concentration of urea. Pores were also formed at higher concentration on the CHAp compacts. → The slow dissociation of urea under hydrothermal conditions is the reason for morphology control.

    It has long been recognized that albedo related vegetation feedbacks amplify climate variability in North Africa. Recent studies have revealed that areas of very high albedo associated with certain desert soil types contribute to the current dry climate of the region. We construct three scenarios of North African albedo, one based on satellite measurements, one where the highest albedo resembles that of soils in the desert transition zones, and one based on a vegetation map for the ''green Sahara'' state of the middle Holocene, ca. 6,000 years ago. Using a series of climate model simulations, we find that the additional amplitude of albedo change from the middle Holocene to the present caused by the very bright desert soils enhances the magnitude of the June-to-August precipitation change in the region of the present Sahara from 0.6 to 1.0 mm/day on average. We also find that albedo change has a larger effect on regional precipitation than changes in either the Earth's orbit or sea surface temperatures between 6,000 years ago and today. Simulated precipitation agrees rather well with present observations and mid Holocene reconstructions. Our results suggest that there may exist an important climate feedback from soil formation processes that has so far not been recognized. (orig.)

  4. Finite element simulation of dynamic wetting flows as an interface formation process

    KAUST Repository

    Sprittles, J.E.

    2013-01-01

    A mathematically challenging model of dynamic wetting as a process of interface formation has been, for the first time, fully incorporated into a numerical code based on the finite element method and applied, as a test case, to the problem of capillary rise. The motivation for this work comes from the fact that, as discovered experimentally more than a decade ago, the key variable in dynamic wetting flows - the dynamic contact angle - depends not just on the velocity of the three-phase contact line but on the entire flow field/geometry. Hence, to describe this effect, it becomes necessary to use the mathematical model that has this dependence as its integral part. A new physical effect, termed the \\'hydrodynamic resist to dynamic wetting\\', is discovered where the influence of the capillary\\'s radius on the dynamic contact angle, and hence on the global flow, is computed. The capabilities of the numerical framework are then demonstrated by comparing the results to experiments on the unsteady capillary rise, where excellent agreement is obtained. Practical recommendations on the spatial resolution required by the numerical scheme for a given set of non-dimensional similarity parameters are provided, and a comparison to asymptotic results available in limiting cases confirms that the code is converging to the correct solution. The appendix gives a user-friendly step-by-step guide specifying the entire implementation and allowing the reader to easily reproduce all presented results, including the benchmark calculations. © 2012 Elsevier Inc.

    Synthesis of crystalline barium stronium titanate (Ba(0.6)Sr(0.4)TiO(3)) nanoparticles and subsequent formation of thin films have been carried out. The crystalline products were confirmed by X-ray diffractometry. Uniform Ba(0.6)Sr(0.4)TiO(3) thin films were formed by using electrophoretic deposition method (EPD) under a 0.3 to 5 V dc bias for 10 min to 1 h. Ba(0.6)Sr(0.4)TiO(3) nanoparticles having an average crystallite size of 20 to 50 nm, and Ba(0.6)Sr(0.4)TiO(3) thin films with thickness of 150 nm to 4 mum were obtained. A scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the morphologies of nanoparticles and thin films. The results show that the EPD process route is a rapid, cost-effective alternative for forming Ba(0.6)Sr(0.4)TiO(3) thin films.

  6. Effects of Fuel Quantity on Soot Formation Process for Biomass-Based Renewable Diesel Fuel Combustion

    KAUST Repository

    2016-12-01

    Soot formation process was investigated for biomass-based renewable diesel fuel, such as biomass to liquid (BTL), and conventional diesel combustion under varied fuel quantities injected into a constant volume combustion chamber. Soot measurement was implemented by two-color pyrometry under quiescent type diesel engine conditions (1000 K and 21% O2 concentration). Different fuel quantities, which correspond to different injection widths from 0.5 ms to 2 ms under constant injection pressure (1000 bar), were used to simulate different loads in engines. For a given fuel, soot temperature and KL factor show a different trend at initial stage for different fuel quantities, where a higher soot temperature can be found in a small fuel quantity case but a higher KL factor is observed in a large fuel quantity case generally. Another difference occurs at the end of combustion due to the termination of fuel injection. Additionally, BTL flame has a lower soot temperature, especially under a larger fuel quantity (2 ms injection width). Meanwhile, average soot level is lower for BTL flame, especially under a lower fuel quantity (0.5 ms injection width). BTL shows an overall low sooting behavior with low soot temperature compared to diesel, however, trade-off between soot level and soot temperature needs to be carefully selected when different loads are used.

    Abdullah, Saiful Arif; Hezri, Adnan A

    2008-11-01

    Agricultural expansion and deforestation are spatial processes of land transformation that impact on landscape pattern. In peninsular Malaysia, the conversion of forested areas into two major cash crops--rubber and oil palm plantations--has been identified as driving significant environmental change. To date, there has been insufficient literature studying the link between changes in landscape patterns and land-related development policies. Therefore, this paper examines: (i) the links between development policies and changes in land use/land cover and landscape pattern and (ii) the significance and implications of these links for future development policies. The objective is to generate insights on the changing process of land use/land cover and landscape pattern as a functional response to development policies and their consequences for environmental conditions. Over the last century, the development of cash crops has changed the country from one dominated by natural landscapes to one dominated by agricultural landscapes. But the last decade of the century saw urbanization beginning to impact significantly. This process aligned with the establishment of various development policies, from land development for agriculture between the mid 1950s and the 1970s to an emphasis on manufacturing from the 1980s onward. Based on a case study in Selangor, peninsular Malaysia, a model of landscape pattern change is presented. It contains three stages according to the relative importance of rubber (first stage: 1900--1950s), oil palm (second stage: 1960s--1970s), and urban (third stage: 1980s--1990s) development that influenced landscape fragmentation and heterogeneity. The environmental consequences of this change have been depicted through loss of biodiversity, geohazard incidences, and the spread of vector-borne diseases. The spatial ecological information can be useful to development policy formulation, allowing diagnosis of the country's "health" and sustainability. The

  11. CO2 + N2O mixture gas hydrate formation kinetics and effect of soil minerals on mixture-gas hydrate formation process

    CO2 mitigation is one of the most pressing global scientific topics in last 30 years. Nitrous oxide (N2O) is one of the main greenhouse gases (GHGs) defined by the Kyoto Protocol and its global warming potential (GWP) of one metric ton is equivalent to 310 metric tons of CO2. They have similar physical and chemical properties and therefore, mixture-gas (50% CO2 + 50% N2O) hydrate formation process was studied experimentally and computationally. There were no significant research to reduce N20 gas and we tried to make hydrate to mitigate N20 and CO2 in same time. Mixture gas hydrate formation periods were approximately two times faster than pure N2O hydrate formation kinetic in general. The fastest induction time of mixture-gas hydrate formation observed in Illite and Quartz among various soil mineral suspensions. It was also observed that hydrate formation kinetic was faster with clay mineral suspensions such as Nontronite, Sphalerite and Montmorillonite. Temperature and pressure change were not significant on hydrate formation kinetic; however, induction time can be significantly affected by various chemical species forming under the different suspension pHs. The distribution of chemical species in each mineral suspension was estimated by a chemical equilibrium model, PHREEQC, and used for the identification of hydrate formation characteristics in the suspensions. With the experimental limitations, a study on the molecular scale modeling has a great importance for the prediction of phase behavior of the gas hydrates. We have also performed molecular dynamics computer simulations on N2O and CO2 hydrate structures to estimate the residual free energy of two-phase (hydrate cage and guest molecule) at three different temperature ranges of 260K, 273K, and 280K. The calculation result implies that N2O hydrates are thermodynamically stable at real-world gas hydrate existing condition within given temperature and pressure. This phenomenon proves that mixture-gas could be

    The conservation of biodiversity is an important issue world wide and in Australia the maintenance of native biodiversity on farms makes an important contribution to overall conservation objectives. This paper seeks to explain Australian farmers' rationale for maintaining biodiversity on their farms for personal as opposed to business reasons by developing a decision-systems theory from in-depth interviews. This difference has implications for policy development. The decision-systems theory is divided into two main sections. The first section contains five parts. (1) A hierarchy of motivation stories, (2) the concept of suitability and availability of opportunities, (3) a hierarchy of three decision-systems, (4) the concept of personal career paths, (5) the concept of Lenses. The second section contains one part, a policy classification system called 'boxes of influence' that suggests how policy developers can use the information in the first section to develop new biodiversity conservation policy. The paper suggests that decision-systems theory could be used to shed new light on current trends in agriculture and become an important investigative tool for policy development concerning the conservation of biodiversity on farms.

  14. The process of construction of evidence: An analysis of the use of indicators in two decisions of innovation policy

    Despite increasing calls for evidence-based policies, knowledge about the practical use of evidences remains limited. This paper studies the process of construction of evidences in decisions of innovation policy to understand how evidences were used. It analysis the use of indicators and other evidences through interviews conducted to inquire about the two decisions: an electric mobility policy and a nanotechnology laboratory. Results show indicators and other evidences were brought to decision processes according to their availability and capacity to support the different interests of the actors and the stakeholders. Their role was influenced by the particular situation of the decision makers. More importantly, the use of persuasive analytical evidences appears to be related with the adversity of the policy context. In addition, research suggests that indicators are one tool among others to foster innovation decisions. In fact, the relatively minor instrumental role of indicators suggests that indicators are mostly a complementary instrument of decision. When used relevantly, indicators can offer support to a decision. But there are other significant influences that need to be taken into account to understand the specific role indicators and other evidences play, such as the social relations of the decision makers and their emotional-intuitive decisions.

  15. Processing effects on core-shell grain formation in zirconium dioxide-modified barium titanate ceramics

    2001-07-01

    Formation of core-shell grains in BaTiO3 based dielectric ceramics is essential to achieve stable dielectric temperature characteristic. This grain core-shell structure consists of a grain core, which is high purity BaTiO3, ferroelectric, and a paraelectric grain shell, where there is a concentration gradient of dopant. Most commonly core-shell additives are ZrO2, CeO2, Nb2O5+CO 2O3. As a result, internal stress is generated due to this dopant inhomogeneity within the grain and the normally sharp phase transition at Curie point becomes diffused. Up to now understanding and control of core-shell grains in BaTiO3 ceramics is still far from satisfying, which is the basis of this thesis work. In this work, processing influences on core-shell grain formation were investigated in the terms of powder size, stoichiometry, particle surface modification by slurry pH and leached Ba2+, pressing pressure and additive effects such as ZrO2, Nd2O3, BaO and flux CuO, BaCuO2, followed by multiple regression analysis to identify significant variables so as to form core-shell grains in a controller manner. It is found that ZrO2 amount; powder size, stoichiometry and temperature/time are most significant in control of core-shell characteristic (low Deltaepsilon% slurry pH; with adequate eutectic liquid phase, uniformly distributed fine grain morphology was achieved with high sintered densities. A dielectric formulation of 0.8˜1.3 wt% ZrO2, and 3 m/o BaCuO2 and 0.1˜0.3 m/o Nd2 O3 was successfully developed to be sintered at 1055˜1085°C/45˜90 min with Deltaepsilon% < 25%. This formulation has the potential to be co-fired with base metal electrodes.

    Mafic Magmatic Enclave (MME) is a common feature in granitic rocks. However, the layered MMEs developed in the outcrop of Cretaceous granite in Taejongdae National Geopark, Busan show various patterns and interesting phenomena providing useful information on the formation of MMEs. We define here the layered MME as MME composed of several contrasting rock shells. Characteristics and origin of MMEs have been studied in several ways; descriptively, geochemically and through isotope studies due to their importance in the evolution of igneous rocks. This study aims to understand the formation mechanism of the composite MMEs, including the reasons for the diversity of the MME rock types. To achieve those tasks, the relationship between the MMEs and the host granite, and difference between the layers were investigated based on petrological, XRF and EPMA analyses. The important results include the followings: the MMEs can be categorized into two main types; Simple-type composed of a single rock type, and Layered-type composed of different surrounded rock shells. Most of the Simple-type have relatively angular shapes and small sizes, and their contacts with the host granite are commonly sharp but some show small dioritic mixing rims. The forming rocks of the simple MMEs are variable from mafic porphyritic, mafic fine to medium grains and felsic coarse-grained dioritic rocks. The layered MMEs have almost circular to elliptical shapes, and show gradual change in composition from mafic and porphyritic texture in the center to fine in the outer shells (like a chilled margin) and again surrounded by a dioritic layer. The dioritic layer shows another chilled margin with the host granite, indicating double cooling mechanism. Some MMEs are injected by granitic materials through cracks. The injection of the granitic materials into the layered MMEs may indicate fracturing during the cooling process. They may indicate two different phases of mingling and one phase of mixing event.

    This commentary reflects upon the article along three broad lines. It reflects on the theoretical choices and omissions, particularly highlighting why it is important to adapt the multiple streams framework (MSF) when applying it in a socio-political context like Vietnam’s. The commentary also reflects upon the analytical threads tackled by Ha et al; for instance, it highlights the opportunities offered by, and raises questions about the centrality of the Policy Entrepreneur in getting the policy onto the political agenda and in pushing it through. The commentary also dwells on the implications of the article for development aid policies and practices. Throughout, the commentary signposts possible themes for Ha et al to consider for further analysis, and more generally, for future research using Kingdon’s multiple streams theory. PMID:27694671

  18. The spatial distribution of microfabric around gravel grains: indicator of till formation processes

    2010-05-01

    Till micromorphology studies in thin sections is an established tool in the field of glacial geology. Often the thin sections are inspected only visually with help of mineralogical microscope. This can lead to subjective interpretation of observed structures. More objective method used in till micromorphology is measurement of apparent microfabric, usually seen as preferred orientation of elongated sand grains. In theses studies only small fraction of elongated sand grains often confined to small area of thin section usually are measured. We present a method for automated measurement of almost all elongated sand grains across the full area of the thin section. Apparently elongated sand grains are measured using simple image analysis tools, the data are processed in a way similar to regular till fabric data and visualised as a grid of rose diagrams. The method allows to draw statistical information about spatial variation of microfabric preferred orientation and fabric strength with resolution as fine as 1 mm. Late Weichselian tills from several sites in Western Latvia were studied and large variations in fabric strength and spatial distribution were observed in macroscopically similar till units. The observed types of microfabric spatial distributions include strong, monomodal and uniform distribution; weak and highly variable in small distances distribution; consistently bimodal distribution and domain-like pattern of preferred sand grain orientation. We suggest that the method can be readily used to identify the basic deformation and sedimentation processes active during the final stages of till formation. It is understood that the microfabric orientation will be significant affected by nearby large particles. The till is highly heterogonous sediment and the source of microfabric perturbations observed in thin section might lie outside the section plane. Therefore we suggest that microfabric distribution around visible sources of perturbation - gravel grains cut

  7. Changing the malaria treatment protocol policy in Timor-Leste: an examination of context, process, and actors’ involvement

    Science.gov (United States)

    2013-01-01

    In 2007 Timor-Leste, a malaria endemic country, changed its Malaria Treatment Protocol for uncomplicated falciparum malaria from sulphadoxine-pyrimethamine to artemether-lumefantrine. The change in treatment policy was based on the rise in morbidity due to malaria and perception of increasing drug resistance. Despite a lack of nationally available evidence on drug resistance, the Ministry of Health decided to change the protocol. The policy process leading to this change was examined through a qualitative study on how the country developed its revised treatment protocol for malaria. This process involved many actors and was led by the Timor-Leste Ministry of Health and the WHO country office. This paper examines the challenges and opportunities identified during this period of treatment protocol change. PMID:23672371

    2006-12-01

    Regional integrated climate assessments are increasingly viewed as critical for informing sound climate policy. Yet, the scientific information in many assessments often is not effectively transformed in to policies to protect the environment. Why are some assessments more effective at informing policies than others? We will provide some insight into this question by describing the lessons learned from a series of regional assessments organized by the Union of Concerned Scientists (UCS). Working with independent experts in the global change research community, UCS has produced assessments in three regions of the US California, the Great Lakes, and the Gulf Coast. The reports from each of these assessments continue to be used by local, state and regional decision-makers in related management and policy initiatives. We attribute the success of these assessments in motivating and supporting climate-related decisions to four factors: (1) credibility, attained both through scientific peer-review and by engaging local scientific and community leaders; (2) regional relevance of assessment focus areas; (3) accessible presentation of the results to non-technical audiences; and (4) wide communication and distribution of the report to the media, the public, civic groups, and public officials.

  14. Holocene loess deposition and soil formation as competing processes, Matanuska Valley, southern Alaska

    2004-01-01

    Although loess-paleosol sequences are among the most important records of Quaternary climate change and past dust deposition cycles, few modern examples of such sedimentation systems have been studied. Stratigraphic studies and 22 new accelerator mass spectrometry radiocarbon ages from the Matanuska Valley in southern Alaska show that loess deposition there began sometime after ???6500 14C yr B.P. and has continued to the present. The silts are produced through grinding by the Matanuska and Knik glaciers, deposited as outwash, entrained by strong winds, and redeposited as loess. Over a downwind distance of ???40 km, loess thickness, sand content, and sand-plus-coarse-silt content decrease, whereas fine-silt content increases. Loess deposition was episodic, as shown by the presence of paleosols, at distances >10 km from the outwash plain loess source. Stratigraphic complexity is at a maximum (i.e., the greatest number of loesses and paleosols) at intermediate (10-25 km) distances from the loess source. Surface soils increase in degree of development with distance downwind from the source, where sedimentation rates are lower. Proximal soils are Entisols or Inceptisols, whereas distal soils are Spodosols. Ratios of mobile CaO, K2O, and Fe2O3 to immobile TiO2 show decreases in surface horizons with distance from the source. Thus, as in China, where loess deposition also takes place today, eolian sedimentation and soil formation are competing processes. Study of loess and paleosols in southern Alaska shows that particle size can vary over short distances, loess deposition can be episodic over limited time intervals, and soils developed in stabilized loess can show considerable variability under the same vegetation. ?? 2004 University of Washington.

  15. Deciphering site formation processes through soil micromorphology at Contrebandiers Cave, Morocco.

    Science.gov (United States)

    Aldeias, Vera; Goldberg, Paul; Dibble, Harold L; El-Hajraoui, Mohamed

    2014-04-01

    Contrebandiers Cave preserves a Late Pleistocene sequence containing Middle Stone Age (MSA) so-called Maghrebian Mousterian and Aterian occupations, spanning from ∼126 to 95 ka (thousands of years ago), followed by spatially restricted Iberomaurusian industries. Micromorphological analyses, complemented by instrumental mineralogical identification and fabric orientation, allowed for the reconstruction of the main site formation processes at the site. Initial deposition is characterized by local reworking of marine shelly sands dating to Marine Isotopic Stage 5e (MIS5e). The subsequent stratification reveals sedimentary dynamics predominantly associated with gravity-driven inputs and contributions from weathering of the encasing bedrock, at the same time that anthropogenic sediments were being accumulated. The allochthonous components reflect soil degradation and vegetation changes around the cave during the last interglacial. Human occupations seems to be somewhat ephemeral in nature, with some stratigraphic units apparently lacking archaeological components, while in others the human-associated deposits (e.g., burned bones, charcoal, and ashes) can be substantial. Ephemeral breaks in sedimentation and/or erosion followed by stabilization are mainly discernible microscopically by the presence of phosphatic-rich laminae interpreted as short-lived surfaces, peaks of increased humidity and colonization by plants. More substantial erosion affects the uppermost Aterian layers, presumably due to localized reconfigurations of the cave's roof. The subsequent Iberomaurusian deposits are not in their primary position and are associated with well-sorted silts of aeolian origin. While the effects of chemical diagenesis are limited throughout the whole stratigraphic sequence, physical bioturbation (e.g., by wasps, rodents, and earthworms) is more pervasive and leads to localized movement of the original sedimentary particles.

    A gap opening process in plasma opening switches (POS) is examined with the aid of numerical simulations. In these simulations, a high density (n e =10 14 --5x10 15 cm -3 ) uniform plasma initially bridges a small section of the coaxial transmission line of an inductive energy storage generator. A short section of vacuum transmission line connects the POS to a short circuit load. The results presented here extend previous simulations in the n e =10 12 --10 13 cm -3 density regime. The simulations show that a two-dimensional (2-D) sheath forms in the plasma near a cathode. This sheath is positively charged, and electrostatic sheath potentials that are large compared to the anode--cathode voltage develop. Initially, the 2-D sheath is located at the generator edge of the plasma. As ions are accelerated out of the sheath, it retains its original 2-D structure, but migrates axially toward the load creating a magnetically insulated gap in its wake. When the sheath reaches the load edge of the POS, the POS stops conducting current and the load current increases rapidly. At the end of the conduction phase a gap exists in the POS whose size is determined by the radial dimensions of the 2-D sheath. Simulations at various plasma densities and current levels show that the radial size of the gap scales roughly as B/n e , where B is the magnetic field. The results of this work are discussed in the context of long-conduction-time POS physics, but exhibit the same physical gap formation mechanisms as earlier lower density simulations more relevant to short-conduction-time POS. copyright 1995 American Institute of Physics

    2011-01-01

    Full Text Available Abstract Background Next Generation Sequencing (NGS technology generates tens of millions of short reads for each DNA/RNA sample. A key step in NGS data analysis is the short read alignment of the generated sequences to a reference genome. Although storing alignment information in the Sequence Alignment/Map (SAM or Binary SAM (BAM format is now standard, biomedical researchers still have difficulty accessing this information. Results We have developed a Graphical User Interface (GUI software tool named SAMMate. SAMMate allows biomedical researchers to quickly process SAM/BAM files and is compatible with both single-end and paired-end sequencing technologies. SAMMate also automates some standard procedures in DNA-seq and RNA-seq data analysis. Using either standard or customized annotation files, SAMMate allows users to accurately calculate the short read coverage of genomic intervals. In particular, for RNA-seq data SAMMate can accurately calculate the gene expression abundance scores for customized genomic intervals using short reads originating from both exons and exon-exon junctions. Furthermore, SAMMate can quickly calculate a whole-genome signal map at base-wise resolution allowing researchers to solve an array of bioinformatics problems. Finally, SAMMate can export both a wiggle file for alignment visualization in the UCSC genome browser and an alignment statistics report. The biological impact of these features is demonstrated via several case studies that predict miRNA targets using short read alignment information files. Conclusions With just a few mouse clicks, SAMMate will provide biomedical researchers easy access to important alignment information stored in SAM/BAM files. Our software is constantly updated and will greatly facilitate the downstream analysis of NGS data.

    1996-01-01

    The kinetic studies of an unsteady formation of hard ZrN and TiN coatings on the surface of metallic (Zr, Ti) samples in an Ar-N plasma flow are carried out. The obtained result is that at the initial stage of an unsteady heating of titanium samples nitrogen atoms penetrate into metal lattice and form interstitial compounds of hard nitrogen solutions in α-phase of Ti. This process is followed by a growth of thin surface layers of titanium nitrides with subsequent changes of surface radiance of exposed samples. Unsteady formation of ZrN is a similar two-stage process which includes the ZrN film growth and formation of a α-hard solution with subsequent changes of total normal emissivity of the surface.

    Drexler, Judith Z.

    2011-01-01

    The purpose of this study was to determine peat formation processes throughout the millennia in four tidal marshes in the Sacramento-San Joaquin Delta. Peat cores collected at each site were analyzed for bulk density, loss on ignition, and percent organic carbon. Core data and spline fit age-depth models were used to estimate inorganic sedimentation, organic accumulation, and carbon sequestration rates in the marshes. Bulk density and percent organic matter content of peat fluctuated through time at all sites, suggesting that peat formation processes are dynamic and responsive to watershed conditions. The balance between inorganic sedimentation and organic accumulation at the sites also varied through time, indicating that marshes may rely more strongly on either norganic or organic matter for peat formation at particular times in their existence. Mean carbon sequestration rates found in this study (0.38-0.79 Mg C ha-1 year-1) were similar to other long-term estimates for temperate peatlands.
