    2015-01-01

    Full Text Available The article looks at some aspects of Yugoslav-Italian economic relations from the end of the First World War to the beginning of the Great Depression. Those relations were not always driven by pure economic interests, but they also had political and strategic aims. Although Yugoslav-Italian political and diplomatic relations were well served in both Serbian/Yugoslav and Italian historiography, little has been written about economic relations between the two countries. Therefore, the article is mainly based on the documents from the Central State Archives (Archivio centrale dello Stato and Historical-Diplomatic Archives of Ministry of Foreign Affairs (Archivio storico-diplomatico del Ministero degli Affari Esteri in Rome, as well as from the Archives of Yugoslavia (Arhiv Jugoslavije in Belgrade.

  2. The Brazil-Angola alkaline - carbonatite province and its main economic aspects

    1982-01-01

    The principal characteristics of the Brazil-Angola Alkaline Carbonatite Province are defined and described with specific reference to tectonic setting and economic aspects. The economic aspects of the Brazilian uranium deposits are emphasised. The Brazil-Angola Alkaline-Carbonatite Province can be divided into six Brazilian sub-provinces and two Angolan sub-provinces. Correlation between the sub-provinces of Brazil and Angola remains speculative due to the lack of detailed information, especially age determinations on the Angolan rocks. However, an analysis of the tectonic and petrochemical aspects suggests that the two Brazilian sub-provinces situated along the littoral of Rio de Janeiro/ Sao Paulo and around the periphery of the Parana Basin may be more easily comparable to the two Angolan sub-provinces than the remaining four.

    2000-06-01

    The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

  5. Political and economic aspects

    1997-01-01

    The political and socio-economic aspects of oil and gas exploration in Canada's Arctic and the Beaufort Sea were reviewed. The federal government was very interested in developing the North because they saw oil and gas development in the North as a means of strengthening sovereignty claims. The projected profits from Northern oil and gas development were also very attractive, and after dealing with environmental and social concerns, the government granted the necessary drilling permits. The federal government also made allowances for huge tax incentives for the oil and gas companies to encourage exploration. Although oil has been found, large-scale production in the Beaufort Sea never materialized. During the period from 1984 to 1988, world prices for oil fell and it was no longer economical to undertake frontier production. Beaufort Sea operation were shut down as the oil industry changed its focus to more cost-effective reservoirs in southern Canada. 1 fig

  8. Economic aspects of decommissioning

    International Nuclear Information System (INIS)

    Jenne, C.

    1988-01-01

    Two viewpoints on decommissioning are quoted; the first suggests that decommissioning can be viewed as a technical detail that is of limited relevance whereas the second suggests that decommissioning is a key financial issue. Both are specifically relevant to United Kingdom nuclear power stations. This paper attempts to reconcile the two views. It suggests that decommissioning does raise some important issues for regulation and financing of a privatised industry but, despite this, the economics of nuclear do remain insensitive. The paper begins by examining the significance of decommissioning costs in a number of contexts, including nuclear unit generating costs and financing requirements. It then addresses the degree of uncertainty in the decommissioning cost estimates. With privatisation on the horizon, the paper considers the significance of decommissioning and the associated uncertainty for the investor; this last section considers regulatory issues raised in relation to funding, accounting policy and electricity pricing.

    Lange, A; Braun, S; Greiner, W

    2012-05-01

    For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

    2018-03-01

    One of the modern economy models is circular economy in which wastes should be considered as resource and used in an efficient and sustainable way. This also concerns to metals included in scraps. However, the need for metal recovery from waste is not only the result of the latest economic trends but also the result of large and constantly changing demand for metals. Shrinking natural sources of metals, concentrations of ores in small number of countries in the world and resulting from this dependence on import, geopolitical situation, new technologies demands are only a few most important determinants that have been changing the structure of the metal market over years. In this chapter, authors focused on the presentation of economic aspects of metal recovery from various sources. The chapter presents the characteristic of metal market elements (supply, demand and price) and changes that took place over decades, underlining the structure of precious and highly desirable metal market elements. Balance between the demand and supply ensures price stability and rationalizes inflation. However, growing demand on many means that secure supply chains, such as recycling and material recovery, are essential to ensure continuity in the supply chain and guarantee unrestricted technological progress and innovation. The data included in this chapter presents also the concentration of different metals and group of metals in wastes pointing that recycling of waste can become one of the possibilities of acquiring missing and critical metals. Metal-laden wastes include a few groups: waste electrical and electronic equipments, catalysts of different application, introduced on chemical, petrochemical or automotive market, galvanic wastes and wastewaters. The profitability assessment of recycling processes is very complicated. Nevertheless cited data shows that profitability of recovery depends on the metal analyzed and the type of waste. It must be underline that an optimized

    Timm, M.

    1975-01-01

    The paper reviews the economic aspects of nuclear fuel based on the year 1975. The focus of attention is on the well-established light-water reactors, which for the time being, and also for the foreseeable future, account for the bulk of the world's nuclear power capacity. The author describes the principal economic aspects of the light-water fuel cycle components and discusses their future development to the extent that this can be foreseen. Various approaches to the formulation of the contract for the supply of light-water fuel are discussed on the basis of the established procedure. After some introductory comments on methods of calculating specific fuel costs, the author describes the main results of fuel cycle calculations. The economic aspects of nuclear fuel for other types of reactors are discussed in the sequence in which it is planned to introduce such reactors commercially. The economic data available apply to reactors ranging from the heavy-water-moderated type, through helium-cooled high-temperature reactors, to the fast breeders, and are based more and more on results of feasibility studies and less on practical operational experience. For this reason the author discusses only the basic data of importance, as viewed from the present-day stand-point, and mentions the emerging trends. It should be pointed out, however, that a comprehensive description of this kind can only show the situation at a given moment. Numerous political, economic and technological influences are in a state of permanent flux, hence economic data and developments may easily change within a short time. (author)

    The main function of the fusion reactor blanket is ensuring tritium breeding and radiation shield. The blanket version depends on the reactor type (experimental, DEMO, commercial) and its parameters. Blanket operation conditions are defined with the heat flux, neutron load/fluence, cyclic operation, dynamic heating/force loading, MHD effects etc. DEMO/commercial blanket design is distinguished e.g. by rather high heat load and neutron fluence - up to 100 W/cm 2 and 7 MWa/m 2 accordingly. This conditions impose specific requirements for the materials, structure, maintenance of the blanket and its most loaded components - FW and limiter. The liquid Li-Pb eutectic is one of the possible breeder for different kinds of blanket in view of its advantages one of which is the blanket convertibility that allow to have shielding blanket (borated water) or breeding one (Li-Pb eutectic). Using Li-Pb eutectic for both ITER and DEMO blankets have been considered. In the conceptual ITER design the solid eutectic blanket was carried out. The liquid eutectic breeder/coolant is suggested also for the advanced (high parameter) blanket

    Economic problems related to the prevention, diagnosis and treatment of rare diseases are presented paying particular attention to the costs of financing treatment, including the issue of its refund, which is a fundamental and difficult to solve economic problem of the health care system. Rare diseases, despite the low frequency of occurrence, together cover a large group of diseases being a serious medical, social and economic problem. The adoption of Polish National Plan for Rare Diseases resulting from the recommendations of the Council of the European Union, the extension of institutional activities related to the area of public health and social initiatives seeking innovative solutions to create a model of social support for patients and their families, with very high complexity of the issues regarding rare diseases, results in the need for a coherent, comprehensive, system operations and adoption of comprehensive solutions.

  17. Globalization: Economic and psychological aspects

    Directory of Open Access Journals (Sweden)

    Ljajić Samir

    2016-01-01

    Full Text Available Globalization requires a change of human identity, stepping out from the field of their own culture and its solutions, which are becoming obsolete, and which block one to fit in. It changes ones understanding, knowledge, morality, competence, which causes insecurity and fear. Quickly unwinding change reduces the ability to predict future which evokes fear and resistance to the arrival of foreigners and their capital and values, which are seen as intrusive and aggressive, and extreme reactions emerge. The idyllic image of global prosperity becomes the image of a global catastrophe. Individuals give in to this pressure and incidence of mental illnesses such as depression, substance abuse, suicide and murder, is rising. The authors conclude that psychology has its place in the study of the influence of globalization on humans. At present, the research of the negative consequences of globalization in general and the economic crisis in particular on man should have primacy, and in this regard preventive actions should be developed in order to avoid deeper disorders in future.

  19. Some economic aspects of recreational injuries.

    Science.gov (United States)

    Arundel, J T

    1974-06-01

    This paper deals with some basic features of accidents in recreation and will attempt to throw some light on their economic consequences. Let us examine sport as one aspect of recreation. As Williams (1973) put it, "Sport is a phenomenon of simple definition, but with well recognised features. It is essentially recreational, essentially physical, frequently competitive and always contrived." The number and type of participants has increased, along with the range of activities available. Classifications of sport, at best, are arbitrary but nevertheless are useful for analysis. These divisions may be land/air/water types; indoor/outdoor; team/individual; body contact/non-contact/vehicular; amateur/professional. Sports injuries are of two types, intrinsic or self-inflicted (Williams, 1973) and extrinsic. Intrinsic injuries refer to those as a result of over-use (leading, for example, to stress fractures) and to specific incidents not involving outside agents. Extrinsic injuries are caused by contact with external objects and form the bulk of injuries sustained in body-contact, vehicular (horses, cars, skis) and environmental-type sports. Extrinsic injuries are generally more severe because greater forces and velocities are involved. Appendix 1 lists the main sporting activities according to location of sport; individual or team participation; likelihood of extensive body contact; and professional status. Professional players not only suffer loss of earning capacity but may reflect a bad investment for an entrepreneur or reduce spectator attendance and gate taking. It is apparent that team sports, having substantial body contact, face a higher risk of moderate to serious injury than do individual, non-contact sports, although major injuries can be sustained in the latter, for example, sprains and dislocations in athletics, golf, tennis, etc. Other sports must be classed as dangerous because of the nature of competition, for example, motor racing and flying. These

  20. Comparative economics of the main electricity sources

    Jones, P.M.S.

    1991-01-01

    Few participants in the Uranium Institute's Symposium would fail to agree that nuclear power has considerable environmental and ecological advantages over fossil fuel combustion. There would, however, be far less unanimity, even among a favourably inclined group, on the economic attractiveness of nuclear power and its competitive position vis-a-vis other electricity generation options. To the layman the conflicting claims are confusing, not least because nuclear power often appears to be the only product surrounded by such controversy. Some of the principal reasons are listed. Of these, deficiencies in understanding and divergent value standards are identified as particularly important. The latter issue has a major effect on comparative economics, when incorporated into the calculations of the cost of nuclear power when compared to its alternatives. In this paper the nature of the comparisons that can usefully be made is defined, then the results of recent international studies and their implications are outlined. Confusions arising from the privatisation of the electricity supply industry in the United Kingdom are examined and the implications of taking a wider view of economic comparisons are examined.

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

    International Nuclear Information System (INIS)

    1989-01-01

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

    Dupuy, M.

    1991-01-01

    As part of the management of a utility, it is necessary to check, beyond the technical aspect, the economic suitability of deciding whether to perform the maintenance or rehabilitation of an installation. The decision criteria involved are to be found within the framework of the utility's management system itself. After having set out the decision-making process of hydroelectric power station maintenance or rehabilitation, the document goes on to give a description of the economic advantage of such an operation. The latter is determined after having properly defined the overall cost of maintenance or rehabilitation: direct expenses and induced costs, and expected savings: economic performance, short and medium-term reduction of expenses as a result of the profitability and productivity of the rehabilitation. The profitability is calculated as the ratio between the economic balance and the amount of the operation. Productivity means the improvement of the utility's management indicators. The random aspect of savings and a simple method making it possible to integrate them into a calculation is mentioned, as well as the classification and aggregation of various operations of a similar nature that have to come into the budget requirements of the utility.

    Ona Rakauskienė

    2015-06-01

    Full Text Available The purpose of research is to develop a conceptual model for assessing the impact of the gender aspect on economic policy at macro– and microeconomic levels. The research methodology is based on analysing scientific approaches to the gender aspect in economics and gender–responsive budgeting as well as determining the impact of the gender aspect on GDP, foreign trade, the state budget and the labour market. First, the major findings encompass the main idea of a conceptual model proposing that a socio–economic picture of society can be accepted as completed only when, alongside public and private sectors, includes the care/reproductive sector that is dominated by women and creating added value in the form of educated human resources; second, macroeconomics is not neutral in terms of gender equality. Gender asymmetry is manifested not only at the level of microeconomics (labour market and business but also at the level of macroeconomics (GDP, the state budget and foreign trade, which has a negative impact on economic growth and state budget revenues. In this regard, economic decisions, according to the principles of gender equality and in order to achieve gender equality in economics, must be made, as the gender aspect has to be also implemented at the macroeconomic level.

    International Nuclear Information System (INIS)

    Meldonian, N.L.; Santos, E.M. dos

    1992-01-01

    This work describes different aspects and parameters that should be regarded as guidelines for economic evaluation of small and medium power plant projects. The main objective of an economic evaluation is to establish the plant's unitary cost and its economic figure of merit. To achieve that, a number of studies must be undertaken to compare the global competitiveness of a nuclear power plant with other energetic alternatives. These studies involve macro economy, energy generation, electricity transmission and global feasibility of the enterprise. It is concluded that the economic evaluation of a nuclear power plant should be considered as the culmination of a long process of planning at a national level. The main reasons are the investments involved, the technological developments required and political implications of the utilization of nuclear power energy. (author)

    Advanced energy technologies span a wide variety of resources, techniques, and end-user requirements. Economic considerations are major factors that shape their harnessing and utilization. A discussion of the basic factors in the economic arena is presented, with particular emphasis on renewable energy technologies--photovoltaics, solar-thermal, wind-electric conversion, biomass utilization, hydro, and tidal and wave energy systems. The following are essential to determine appropriate energy system topologies: proper resource-need matching with an eye on the quality of energy requirements, integrated use of several resources and technologies, and a comprehensive consideration which includes prospecting, collection, conversion, transportation, distribution, storage and reconversion, end use, and subsequent waste management aspects. A few case studies are included to apprise the reader of the status of some of the key technologies and systems

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

    Directory of Open Access Journals (Sweden)

    Otakar Schlossberger

    2016-06-01

    Full Text Available The term “electronic money” first appeared in Czech legislation in 2002 as the result of the transposition of legislation into the Czech Republic’s legal system in anticipation of the country’s accession to the European Union. This term subsequently reappeared in 2009 during the recodification of the legal regulation of payment services, payment systems and electronic money. At this time, the definition was subjected to certain changes which continue to exert a significant influence on current practice with respect to the issuance and subsequent use of electronic money. This paper addresses the term “virtual money” and considers the mutual relationships between “electronic money”, “cashless money” and “virtual money” from the point of view of selected legal and economic approaches. The aim of the paper is to employ the analytical method in order to investigate selected legal and economic aspects of the various interpretations of the categories “electronic money”, “cashless money” and “virtual money”. A comparative analysis approach will be applied so as to ascertain both the legal and economic differences between these categories and general conclusions will be suggested employing the deduction method. The article is further concerned with the influence of these categories on the monetary base and money supply indicators.

    Analyses made in Europe after the accident in Chernobyl Nuclear Power Plant have shown that the key-element with the biggest impact on the development of consequences during and immediately after the accident was deficient notifying which was also unsystematic and in disorder. Therefore, scientific and expert organisations of the European Union have been faced with the task of system development above all meant to improve communication between European countries in terms of measured parameters exchange (the radiological and meteorological ones), that would be generally applicable in all the European countries. Development of such a system going by the name of RODOS (Real Time On Line DecisiOn Support) began in 1989 within the framework of the European Commission's research and technological development program. The main aspects associated with the implementation of the RODOS system in Croatia are described within this article. By the main aspects of implementation we mean technical prerequisites that the Republic of Croatia is due to fulfil before joining in, and they include activities like: (1) translating users' interfaces into Croatian, (2) adapting various models in consistence with local parameters, (3) collecting geographical data, (4) making specific local maps and collecting statistical data (GIS), and (5) linking the RODOS real-time data base with the net of local measure stations (radiological and meteorological). Activities of this scale and technically so demanding, request certain organisational prerequisites as well as considerable material resources. From the point of view of the Republic of Croatia, establishment of the RODOS system and inclusion into the real-time international exchange of measured radiological data would mean major improvement of the nuclear emergency response preparedness system.

    Full Text Available The purpose of the study is to highlight the main issues of developing countries regarding cybercrime and examine the possible link between weak economic development and escalating levels of cybercrime. The findings were established on the basis of literature review, comparative studies and the synthesis of findings. The existing sociological theories of crime are not limited to traditional crime and may be used for the interpretation of its cyber version. By analysing individual sociological theories and the results of empirical research, we found that social-economic factors, such as GDP per capita, unemployment and education, are closely related to the incidence of cybercrime in different countries. This enables us to conclude that the relatively poor economic development is one of the reasons contributing to a higher incidence of cybercrime in Eastern European countries. By taking into account factors of different nature, one could increase the understanding of cybercrime and the possibility of adopting and implementing reliable preventive measures. However, this paper strives not only to understand the factors related to cybercrime, but also to raise awareness, stimulate a proactive approach and develop preventive actions in the fight against cybercrime.

  15. Economic aspects of risk assessment in chemical safety

    Energy Technology Data Exchange (ETDEWEB)

    Drummond, M F; Shannon, H S

    1986-05-01

    This paper considers how the economic aspects of risk assessment in chemical safety can be strengthened. Its main focus is on how economic appraisal techniques, such as cost-benefit and cost-effectiveness analysis, can be adapted to the requirements of the risk-assessment process. Following a discussion of the main methodological issues raised by the use of economic appraisal, illustrated by examples from the health and safety field, a number of practical issues are discussed. These include the consideration of the distribution of costs, effects and benefits, taking account of uncertainty, risk probabilities and public perception, making the appraisal techniques useful to the early stages of the risk-assessment process and structuring the appraisal to permit continuous feedback to the participants in the risk-assessment process. It is concluded that while the way of thinking embodied in economic appraisal is highly relevant to the consideration of choices in chemical safety, the application of these principles in formal analysis of risk reduction procedures presents a more mixed picture. The main suggestions for improvement in the analyses performed are the undertaking of sensitivity analyses of study results to changes in the key assumptions, the presentation of the distribution of costs and benefits by viewpoint, the comparison of health and safety measures in terms of their incremental cost per life-year (or quality-adjusted life-year) gained and the more frequent retrospective review and revision of the economic analyses that are undertaken.

    The classical macro-economic aggregate production function considered that output as measured by Gross Domestic product (GDP) was the result of the factor inputs: land, labour and capital. The production function was given by: GDP=f(Land, Capital, Labour). We propose: GDP=function (LAND, CAPITAL, LABOUR, ENERGY, TECHNOLOGY, INFORMATION), GDP=function(Z, K, R, E, T, I). Measuring effects of these variables on growth of GDP over longer periods of time is difficult statistical and mathematical task. Mathematical relations are not derived but instead historical exposition with a selection of statistical data was given to prove validity of the production function relation. through long historical periods, energy was reduced to energy of animal and human muscles sometimes with a help of mechanical levers and mechanisms. With coal use in 18th century animal and human muscles are no more main energy sources but in substitute to them thermal machines (from steam reciprocating machines to Otto, diesel machines in combination with electric machines) startedto be main movers of industrial age with high energy intensity. Energy as general thermodynamic concept for availability or ability of substance to produce work was introduced. Between primary forms of energy crude oil like fuel with greatest energy or ability to produce mechanical work, specially in transport takes the dominant place in 20th and 21st century. Use of crude oil in gas turbines, internal combustion engines, reaches upper levels of efficiency, but in the same time there is no technology that could substitute it in the transport. Influence of crude oil on prices and all other forms of energy and as political and economic factor is considered. (author)

    Full Text Available Nuclear power in its present form was created during the Cold War and is its heritage. The main objective of nuclear energy at that time, along with energy, was the creation and accumulation of nuclear materials. To this aim a existing nuclear power plants based on uranium-plutonium cycle. Everything else - the processing of radioactive waste and spent nuclear fuel, storage, recycling themselves nuclear power plant after its end of life, the risks of proliferation of nuclear materials and other environmental issues - minor. It was also believed that the nuclear power plant - the most reliable and safe plant. During the last twenty years all over the world the number of new orders for nuclear aggregates has decreased. That happens for a number of reasons, including public resistance, that the construction of new NPP and the excess of energy utilities in many markets, which is mainly connected with high market competition in energy markets and low economic indicators of the current nuclear utilities. The technology that consists of low capital costs, a possibility for quick construction and guarantied exploitation quality is on the winners side, but currently this technology is absent. However, despite abovementioned downsides, as the experience of state corporation "Rosatom"has shown, many developing countries of the South-east Asia, The middle East, African regions express high interest in the development of nuclear energy in their countries. The decision whether to develop nuclear energy or to continue to develop is, in the end, up to the choice of the tasks that a country faces. The article describes these "minor" issues, as well as geopolitical and economic problems of the further development of nuclear energy.

    The estimated, analysed and founding of the economical aspect at decommissioning of Nuclear Power Plant (NPP) have been studied. The data that have been obtained from literature, then the calculation and analysing have been done base to the future condition. The cost for NPP decommissioning depend on the internal factor such as type, capacity and safe storage time, and the external factor such as policy, manpower and the technology preparation. The successfulness of funding, depend on the rate of inflation, discount rate of interest and the currency fluctuation. For the internal factor, the influence of the type of the reactor (BWR or PWR) to the decommissioning cost is negligible, the big reactor capacity (±1100 MW), and the safe storage between 30 to 100 years are recommended, and for the external factor, specially Indonesia, to meet the future need the ratio of decommissioning cost and capital cost will be lower than in develop countries at the present (10%). The ratio between decommissioning fund and electricity generation cost relatively very low, are more less than 1.79 % for 30 years safe storage, and discount rate of interest 3%, or more less than 0.30 % for safe storage 30 years, and discount rate of interest 6%.

    The High Temperature Reactor (HTR), as the only nuclear system producing high temperature heat up to 1000 deg. C, offers a wide variety of applications. Besides electricity production, via steam turbines and in future via gas turbines, there is: District heat with high efficiency, long distance energy for urban energy supply, high pressure injection steam production for enhanced oil recovery, medium range temperature heat direct application in chemical and related industry and last not least, high temperature application for the refinement of fossil energy carriers. Recent results of studies and programmes will be presented: Near term applications are identified, e.g. refineries and alumina industry with smaller HTR units. Another large market is the production of hydrogen, methanol and ammonia on the basis of natural gas, the relevant technology has been developed up to the pilot scale. The refinement of fossil energy carriers, in particular of coal, is subject of the R+D programme in the cooperation between German industrial companies and the Nuclear Research Center. The results are very promising and will be explained in detail. This programme will be continued. Objectives are: improvement of the technology and of the economics as well as environmental aspects, e.g. the reduction of emissions of carbon-dioxid. The topics of the programme deal with the different apparatus, e.g. steam methane reformer, steam coal gasifier, intermediate heat exchanger and last not least, the process heat HTR. (author)

    We reviewed all peer-reviewed papers analysing the cost-effectiveness of vertebroplasty and balloon kyphoplasty for osteoporotic vertebral compression fractures. In general, the procedures appear to be cost effective but are very dependent upon model input details. Better data, rather than new models, are needed to answer outstanding questions. Vertebral augmentation procedures (VAPs), including vertebroplasty (VP) and balloon kyphoplasty (BKP), seek to stabilise fractured vertebral bodies and reduce pain. The aim of this paper is to review current literature on the cost-effectiveness of VAPs as well as to discuss the challenges for economic evaluation in this research area. A systematic literature search was conducted to identify existing published studies on the cost-effectiveness of VAPs in patients with osteoporosis. Only peer-reviewed published articles that fulfilled the criteria of being regarded as full economic evaluations including both morbidity and mortality in the outcome measure in the form of quality-adjusted life years (QALYs) were included. The search identified 949 studies, of which four (0.4 %) were identified as relevant with one study added later. The reviewed studies differed widely in terms of study design, modelling framework and data used, yielding different results and conclusions regarding the cost-effectiveness of VAPs. Three out of five studies indicated in the base case results that VAPs were cost effective compared to non-surgical management (NSM). The five main factors that drove the variations in the cost-effectiveness between the studies were time horizon, quality of life effect of treatment, offset time of the treatment effect, reduced number of bed days associated with VAPs and mortality benefit with treatment. The cost-effectiveness of VAPs is uncertain. In answering the remaining questions, new cost-effectiveness analysis will yield limited benefit. Rather, studies that can reduce the uncertainty in the underlying data

    Full Text Available This study provides an analysis of several problematic factors preventing Kosovo’s economic development. Several sectors that could have been the main pillars of economic development, such as manufacturing, energy, mines and minerals, and other economic sectors have been neglected from the development by domestic institutions or were used clandestinely by certain interest groups, whose focus was not in the development of the country but rather their personal gain. Trade remained the preferred activity throughout these years, which cannot be considered a beneficial sector for economic development, as much as manufacturing, which remains to date as Kosovo’s most underdeveloped sector. As long as Kosovo’s exports cover only 12% of total imports, no economic growth can be expected. Kosovo’s failure to attract strategic investors in years, which could open new jobs, has also contributed its lack of sufficient economic development. Thus, the most concerning issue during this period is the decline in foreign direct investments, which were expected to increase after the declaration of independence. In the lack of a long-term development strategy for certain sectors or priority activities, such as mines, energy, industry etc., there is no progress in the country's economic development. The main issue is that we should only favor those activities or identify segments where we have competitive advantages compared to other countries.

  8. Radioactive sodium waste treatment and conditioning. Review of main aspects

    International Nuclear Information System (INIS)

    2007-01-01

    This publication reviews the main aspects relating to the treatment and conditioning of radioactive sodium waste. This waste arises from the operation of liquid metal fast reactors (LMFRs). In this type of reactor, sodium (Na) or sodium-potassium alloys (NaK) are used as a low-effect neutron moderating coolant medium for extracting and transferring thermal energy from the core and they represent a significant technical and safety challenge during operation and decommissioning. This publication provides the reader with technologically oriented information on the present status of sodium waste management approaches and recent achievements related to treatment and conditioning, with the objective of facilitating planning and preparatory work for the decommissioning of LMFRs. This publication provides a comprehensive review of the hazards associated with sodium waste management. Given the large quantities of sodium waste arising during decommissioning or reactor refurbishment, as well as the challenges and varied techniques associated with removal of 100% of all sodium and NaK bulk quantities and residues during decommissioning, a hazards review and analysis is a critical component in planning the dismantling and waste management activities. Roughly half of this publication focuses on sodium waste generating, handling and treatment processes. This includes draining sodium and NaK from plant systems; in situ treatment of residual sodium; cutting techniques for pumps, valves, piping and other components; cleaning of components; potential reuse of sodium; and removal of selected radionuclides from sodium waste with the objective of reducing the waste classification or converting it to exempt waste. The focus is on proven techniques and technologies, and each discussed method includes a review of the associated principle or theory, practical applications, advantages and disadvantages, limitations, industry experience, and final waste products.

    Morgan, J.C.

    1979-05-01

    Three problems of stellar evolution are considered: the gap in the HR diagram of M67, the evolutionary status of RS CVn binaries and the solar neutrino problem. The physical basis of the Eggleton stellar evolution computer program is described. The program was used to calculate a grid of evolutionary tracks for models with masses between 0.7 and 1.29 solar masses. The more massive stars considered here have expanding convective cores during their main sequence evolution. The isochrone of the old galactic cluster M67 has a gap at the top of its main sequence because of the rapid evolution of stars at hydrogen exhaustion. RS CVn binaries present a complex collection of observational phenomena although they appear to be detached binaries. Their evolutionary status has remained controversial because of their high space density. Here it is shown that a post main sequence interpretation is satisfactory. Models of the Sun with metal poor interiors have been proposed in an attempt to resolve the solar neutrino problem. Here the evolution of two such models is calculated in detail, including a gradual contamination of the surface convection zone to produce the observed metal abundance, giving fully consistent models of the Sun as it is observed.

  18. Economic and financial aspects of mine closure

    Kahn, James R.; Franceschi, Dina; Curi, Adilson; Vale, Eduardo

    2001-01-01

    Today, mine reclamation is a key component to a successful mine plan. Most of the industrialized nations have recognized the need to make mining activities relatively environmentally friendly, if they want to continue to benefit from the economic gains from mineral resource development. Countries such as the United States, Canada, Australia and South Africa are leaders in the field and have implemented relatively sophisticated legislation to ensure environmentally correct mine closure. These countries rely on a combination of strict control strategies and economic penalties to ensure compliance. Yet, from the firm's perspective, reclamation activities are counterproductive as they cut into properties. In order to attract economic development and earn much needed economic capital, most of the rest of the world, particularly the developing countries, lack effective mine closure legislation. The traditional command and control type of legislation that is sometimes used is either vague and therefore avoided, or not enforced appropriately, resulting in an undesirable level of environmental degradation. With the use of case studies from Brazil, this article shows that direct controls are effective in some instances and not in others. It proposes that economic and financial tools may be more effective than the traditional direct controls in getting firms to comply with environmental standards, particularly in developing countries where environmental compliance is more difficult to achieve. It explains the use of performance bonding as one type of economic incentive that has proven to be an effective environmental policy in mine planning and closure. The authors additionally push beyond the typical style of performance bonds to introduce a flexible bonding and insurance system that allows governments to maintain strict environmental standards but limits firms financial exposure during the mining process. Such a system learns from the successes of the industrialized

    The usual parameter space for examining scenarios for heavy ion fusion power plants has generally been based on large, slow cycling, reactor chambers which are only marginally different from chambers proposed for laser drivers. This paper will examine the economic implications of assuming that an inexpensive, low gain pellet is available and that a suitable high-repetition rate reactor has been devised. Interesting scenarios are found that generate economically feasible power from a system with a minimum net capacity of approx. 1 GWe compared to the larger approx. 4 GWe required in previous studies

    According to the final consensus of a panel of intense discussions, the health care system should/can not be excluded from the economic laws of efficiency. Appropriate adaptation of various methods and instruments of economics make these tools applicable for use in the health care system. Due to errors in the implementation of economic methods, though, the question arises who is economically responsible in the health care system. The answer is found at three different levels of the health care system. The physician plays a leading role, both personally and professionally, in being primarily responsible for the direct medical treatment of the patient. The physician's dependence, however, on the health care system reduces his independence, which markedly affects his decision-making and treatment. Management of and in health care institutions is largely independent of the profession learned. Managers and physicians acting as managers must be appropriately and duly educated in the necessary specific talents and knowledge. The organisation of a health care system should also be reserved for trained specialists where the physicians as well as other professionals are obliged to acquire the skills necessary.

It is concluded that determination of electric power generation cost should be based on the fact, that plutonium cost is dictated only by expenses for its extraction from the spent fuel. The cost of the first critical load is not included into capital investments, and investment charges should be sufficiently lower, than standard ones. 5 refs

  15. Economic Aspects of the Chemical Industry

    Science.gov (United States)

    Koleske, Joseph V.

    Within the formal disciplines of science at traditional universities, through the years, chemistry has grown to have a unique status because of its close correspondence with an industry and with a branch of engineering—the chemical industry and chemical engineering. There is no biology industry, but aspects of biology have closely related disciplines such as fish raising and other aquaculture, animal cloning and other facets of agriculture, ethical drugs of pharmaceutical manufacture, genomics, water quality and conservation, and the like. Although there is no physics industry, there are power generation, electricity, computers, optics, magnetic media, and electronics that exist as industries. However, in the case of chemistry, there is a named industry. This unusual correspondence no doubt came about because in the chemical industry one makes things from raw materials—chemicals—and the science, manufacture, and use of chemicals grew up together during the past century or so.

  16. Economic aspects of pneumococcal pneumonia: a review of the literature.

    Science.gov (United States)

    De Graeve, Diana; Beutels, Philippe

    2004-01-01

    In this review, the economic aspects of pneumococcal pneumonia are analysed, including the costs, cost effectiveness and cost benefit of treatment and prevention. We identified eight cost-of-illness studies, 15 analyses comparing the costs of different treatment options and 15 economic evaluations of prevention that met our search criteria. The studies were conducted largely in Europe and the US. Most pertained to community-acquired pneumonia (CAP) in general, without specific analysis of pneumococcus-related illness. Many of the studies were considered to be of poor quality for the following reasons: comparison without randomisation or control variables, disregard of health outcomes, small sample size, restriction of costs to drug costs and vague or disputable sources of cost information. In the US, hospitalisation costs resulting from CAP can be estimated to be between US 7,000 dollars and US 8,000 dollars per admission or US 4 million dollars per 100,000 population. Hospitalisation costs are significant (representing about 90% of total costs), but are much lower in Europe than in the US (one-third to one-ninth of the US estimates in the UK and Spain, respectively). In general, economic studies of treatment for pneumococcal pneumonia are in line with clinical evidence. A drug with proven clinical effectiveness would also appear to be supported from an economic stand point. Furthermore, economic data support an early switch from an intravenous to an oral antibacterial, the use of quinolones for inpatients with CAP, and also the use of guidelines built on clinical evidence. Of all the possible preventive strategies for pneumococcal pneumonia, only vaccination has been subjected to economic evaluation. Pneumococcal polysaccharide vaccine seems relatively cost effective (and potentially cost saving) for those between 65 and 75 years of age, for military recruits and for HIV positive patients with a sufficiently high CD4 cell count.

    Vesely, P.; Borovicka, M.

    2001-01-01

    The paper discusses some aspects of high burnup program implementation at Dukovany NPP and its influence on the fuel cycle costs. Dukovany internal fuel cycle is originally designed as a three years cycle of the Out-In-In fuel reloading patterns. These reloads are not only uneconomical but they additionally increased the radiation load of the reactor pressure vessel due to high neutron leakage typical for Out-In-In loading pattern. To avoid the high neutron leakage from the core a transition to 4-year fuel cycle is started in 1987. The neutron leakage from the core is sequentially decreased by insertion of older fuel assemblies at the core periphery. Other developments in fuel cycle are: 1) increasing of enrichment in control assemblies (3.6% of U-235); 2) improvement in fuel assembly design (reduce the assembly shroud thickness from 2.1 to 1.6 mm); 3) introduction of Zr spacer grid instead of stainless steel; 4) introduction of new type of assembly with profiled enrichment with average value of 3.82%. Due to increased reactivity of the new assemblies the transition to the partial 5-year fuel cycle is required. Typical fuel loading pattern for 3, 3.5, 4 and 5-year cycles are shown in the presented paper. An evaluation of fuel cost is also discussed by using comparative analysis of different fuel cycle options. The analysis shows that introduction of the high burnup program has decrease relative fuel cycle costs

  18. Economic aspects of virtual water trade

    Although water is rarely traded over long distances by itself, the total weight of the water consumed to produce traded commodities exceeds the weight of any other commodity traded in the world. This concept is known as virtual water trade. Although space-/time-/commodity-based quantification has been conducted extensively, the underlying causes of this peculiar feature have thus far received little exploration. Here, we use estimates of water consumption from a global hydrological model and statistical data related to food trade to elucidate three facts that explain the fundamental nature of virtual water trade with respect to alleviating water scarcity. First, we quantitatively illustrate the unique position of water among commodities based on its unit price and quantity of sales. Water has an extremely low unit price, and a tremendous volume of water is consumed per person each day. Second, we show that rich but water-scarce countries tend to reduce local water consumption by importing virtual water. Third, we demonstrate that nations characterized by net virtual water exports have higher water resources and income per capita and that no countries fall below a certain threshold with respect to both GDP and water resources. These points suggest that the virtual water trade is explained by economic characteristics of water and that sustainable development depends on promoting the co-development of poverty alleviation and water resource development.

    The abandonment of fields in the North Sea raises a number of physical, environmental, and economic issues. Key economic aspects are (a) the costs incurred in the abandonment operations: (b), the criteria to be employed in determining the optimal timing of field abandonment; (c), the fiscal reliefs available for the expenditures incurred; and, (d) the (financial) security aspects relating to the activity. These topics are discussed in this paper with particular reference to the UK Continental Shelf (UKCS). Comparisons with Norway and the Netherlands are made on the fiscal aspects. (Author)

    A cost-benefit analysis is done for the fast sodium-cooled reactor project (SNR) as compared to power generation by light water-cooled reactors (LWR). The method is comparable with the calculations of the Netherlands Economic Institue (NEI). The conclusions are as follows: 1. Comparison of the costs of LWR and SNR teaches that even in case of a rise in the price of uranium to $ 200/kg and a high estimate of specific investment costs of LWR of fl. 1600/kWc, it will be necessary for the specific investment costs of the SNR to decrease from fl. 6000/kWc to fl. 2000/kWc which, due to scale and learning effects, is not likely to happen before the turn of the century. 2. The cost-benefit analysis, not including external effects (benefits only from power generation) leads to a cost-benefit ratio of 40,15 and 5% for a self developed SNR, assuming that the commercial introduction of the SNR will be possible at once, after 10 and after 20 years respectively. This means that participation in the SNR project should be discontinued on the basis of this analysis. 3. Inclusion of spin-off effects benefits for enterprises (more than 80% of the total benefits as compared to a maximum of 20% from power production according to NEI) also requires the calculation of other external costs and benefits. In the absence of concise data for these costs and benefits, a decision can only be made on the basis of conclusions 1. and 2

    Interest for nuclear energy had resurgence since the beginning of the new century. This was a consequence of the new world conditions and needs: increasing energy demands (mainly from developing countries), awareness of the importance of energetic security and the necessity of limiting carbon emissions. In this nuclear boom, Small Modular Reactors (SMRs) develop and start to consolidate as a viable option for the present energy market. Their modular characteristics, lower initial capital cost, passive safety features and their niche applications, situate them as a technology with various advantages. The following study will present and analysis that will help to comprehend the SMRs present status. Information will show planned reactors, reactors in construction and in operation, advantages and challenges of their implementation, relevant economic aspects and important licensing factors that need to be highlighted. The analysis showed that the SMR technology is still in an initial stage that could reach and important development point in the next ten years. In this period, many of the reactors that are in design stage or that are through their licensing process might be constructed and could be getting ready for a commercial status. On the other hand, it has been observed that there are two main economic factors that need to be considered for any SMRs implementation project. First, the costs (initial, operation, maintenance, fuel and decommissioning) and second their possible niche market applications. Additionally, it has been noted that the licensing process is one of the greatest challenges for SMR general development. Licensing is mainly related to topic such as Emergency Planning Zone, first-of-a-kind engineering, passive safety features, proliferation resistance, multiple module designs and staffing. Previous information will serve as a base for carrying out a feasibility assessment analysis for SMR in Mexico. This part will be the last section of the project

    Full Text Available Introduction. Modern business conditions and comprehensive economic globalization put the banking institutions at the forefront of the task of achieving and maintaining a high level of competitiveness both on the domestic and on the external financial markets, as banks serve as the main intermediaries in the whole complex of relationships between different economic subjects. To achieve and maintain the competitiveness of banks it is important to create an effective management mechanism, which determines the relevance of the chosen topic. Purpose. The purpose of the work is to summarize the existing theoretical aspects concerning the competitiveness of banks and develop organizational and economic approaches to its enhancement and implementation in banking practice. Results. The article generalizes the notion of competitiveness as an economic category and defines the main approaches of scientists to its interpretation. The role and importance of foreign capital in the banking system and its impact on the competitiveness of banks are considered, and the share of foreign capital in the authorized capital of banks for the period of 2008-2017 is calculated. On the basis of the comparative analysis, the impact on the competitiveness of the largest banking institutions of Ukraine on the performance indicators, such as volumes of assets, liabilities of banks and capital adequacy, was investigated. The possibility of increasing the efficiency of the mechanism of ensuring competitiveness according to the process approach is outlined. By means of the Microsoft Office Visio software system, the Bank’s own Banking Business Management business process was built to ensure the bank’s viability and its structural analysis according to the IDEF0 standard of the SADT methodology. Conclusions. The relationship between the analysis of the bank’s position and the development of its development strategy is important for the understanding and effective management

    The RELAP5 best-estimate thermal-hydraulic system code has been coupled with the PANTHER three-dimensional (3-D) neutron kinetics code via the TALINK dynamic data exchange control and processing tool. The coupled RELAP5/PANTHER code package is being qualified and will be used at British Energy (BE) and Tractebel Energy Engineering (TEE), independently, to analyze pressurized water reactor (PWR) transients where strong core-system interactions occur. The Organization for Economic Cooperation and Development/Nuclear Energy Agency PWR Main-Steam-Line-Break (MSLB) Benchmark problem was performed to demonstrate the capability of the coupled code package to simulate such transients, and this paper reports the BE and TEE contributions. In the first exercise, a point-kinetics (PK) calculation is performed using the RELAP5 code. Two solutions have been derived for the PK case. The first corresponds to scenario, 1 where calculations are carried out using the original (BE) rod worth and where no significant return to power (RTP) occurs. The second corresponds to scenario 2 with arbitrarily reduced rod worth in order to obtain RTP (and was not part of the 'official' results). The results, as illustrated in Fig. 1, show that the thermalhydraulic system response and rod worth are essential in determining the core response. The second exercise consists of a 3-D neutron kinetics transient calculation driven by best-estimate time-dependent core inlet conditions on a 18 T and H zones basis derived from TRAC-PF1/MOD2 (PSU), again analyzing two scenarios of different rod worths. Two sets of PANTHER solutions were submitted for exercise 2. The first solution uses a spatial discretization of one node per assembly and 24 core axial layers for both flux and T and H mesh. The second is characterized by spatial refinement (2 x 2 nodes per assembly, 48 core layers for flux, and T and H calculation), time refinement (half-size time steps), and an increased radial discretization for solution

    Full Text Available The problem of ambiguous interpretation of the category of "efficiency". Taking into account the fact that economic efficiency is quite complex and multifaceted category, coupled with the economic laws and applies to all activities of the enterprise this figure is one of the essential characteristics of the processes occurring in industrial organizations. The lack of a generally accepted view among domestic and foreign economists regarding the essential part of the index of efficiency of activity of the industrial enterprise leads to the impossibility of its use for the management of processes. In the conditions of market economy, the task of economic evaluation res ults of the economic entity remains an important element of the research aspects of the company. Each new refinement of recorded knowledge acts as a stimulus for the development of fundamental knowledge categories. One of the Central in the system of economic categories, in our opinion, is indicated for the effective functioning of the enterprise." Precise formulation of the conceptual framework, criteria-based composition have important theoretical value to justify the subject of any research conducted in the conditions of modern economic development of the global space. The definition of criteria and performance indicators, as well as developing sound economic policies of improving the economic mechanism of enterprise depend on a comprehensive study of the essence of economic efficiency of industrial enterprises of the industry. The article examines the main approaches to the definition of economic efficiency, as well as identify the degree of relation of the category of "efficiency" with other economic categories.

    Full Text Available This paper examines the structuralist tradition in economics, emphasizing the role that structures play in the economic growth of developing countries. Since the subject at hand is evidently too large to cover in a single article, an emphasis has been brought to bear upon the macroeconomic elements of such a tradition, while also exploring its methodological aspects. It begins by analysing some general aspects of structuralism in economics (its evolution and origins associated with ECLAC thought, in this instance focusing on the dynamics of the center-periphery relationship. Thereafter, the macroeconomic structuralism derived from the works of Taylor (1983, 1991 is presented, followed by a presentation of neo-structuralism. Centred on the concept of systemic competitiveness, this approach defines a strategy to achieve the high road of globalization, understood here as an inevitable process in spite of its engagement being dependent on the policies adopted. The conclusions show the genuine contributions of this tradition to economic theory.

    In a difficult economic situation it was considered advisable to inform users of certain financial aspects of radionuclide production for nuclear medicine. Two aspects of this vast and many-sided problem are developed here: - The cost price structure of different products (radiopharmaceutical and radioimmunological) which defines the size of the market consistent with a balanced budget. This aspect of the economic analysis seems all the more important as ORIS, although a non profit-making organization, has to balance its production costs. - The effects on the national economy of the nuclear medicine supply market. From this viewpoint it seemed interesting to examine the share-out of the French market between ORIS which is practically the only national producer and importers, as well as the balance of payments situation in this respect [fr

    Full Text Available The article deals with studying the most important macroeconomic indicators characterizing the trends in the social and economic development of Ukraine for the period 2010–2017. Particular attention is paid to the index of nominal and real gross domestic product (GDP, including per capita, and to the factors that restrain its growth. An analysis of inflation processes using the dynamics of price indices (GDP Deflator, Consumer Price Index is carried out. Furthermore, the problem of unemployment and employment, their impact on GDP dynamics are highlighted. Some aspects of Ukraine’s financial and economic stability are assessed on the basis of analysis of the performance of government debt obligations, balance of payments, and investments. As a result of the conducted research, it is revealed that during the last 2016-2017 there observed a partial stabilization of the socio-economic state of the national economy and its transition to the phase of recovery (in particular, the real GDP growth was 2.5 %, inflation — only 1.3 %, and unemployment — only 0.2 %. However, the analyzed indicators testify to the still relatively low rates of economic recovery caused by the previous loss of production capacities, interbranch and logistics links in the interregional and foreign economic space, restriction of access to energy raw materials, devaluation of the national currency, and growth of investment risks. As a result, the directions of addressing the main unsolved problems for the transition to sustainable economic growth are outlined.

    Some engineering and economic aspects for deployment of centralized nuclear boilers (NB) in the USSR are considered. Engineering, maintenance and economic features of NB as compared to organic-fuelled boilers and nuclear thermal power plants are discussed. Among major factors governing economic efficiency of NB underlined are oraganic fuel costs, reactor unit power, location relative to heat-consuming centres and capacity factor. It is concluded that NB can be economical for heating large consumers (more than 1500 G kal/hr). At the periphery NB can be competitive already at reactor unit power of several MWth. The development of HTGR type reactor-based nuclear-chemical boilers and lines for heat transport in a chemically bound state (e.g., CH 4 → H 2 +CO 2 +CO → CH 4 ) opens the way for a substantial breakthrow in the centralized NB efficiency

    An assessment of economy aspect for nuclear desalination selection has been carried out. This study compares the costs of water production for the Multi Stage Flash Distillation (MSF), Multi Effect Distillation (MED) and Reverse Osmosis (RO) desalination process coupled to PWR. Economic analysis of water cost are performed using the DEEP-3.1. The results of the performed case study of Muria Peninsula showed that the water cost to desalination process coupled with PWR nuclear power plant (at 5% interest rate, 2750 m 3 /day capacity, 28 o C temperature, 28.700 ppm TDS) with MSF plant is the highest (1.353 $/m 3 ), compared to 0.885 $/m 3 and 0.791 $/m 3 with the MED and RO plants respectively. As for MSF process, water cost by RO are also sensitive to variables, such as the interest rate, temperature and total salinity. However, MED process is sensitive to interest rate and temperature based on the economic aspect. MSF and MED plants produce a high-quality product water with a range of 1.0 - 50 ppm TDS, while RO plants produce product water of 200 - 500 ppm TDS. Water requirements for reactor coolant system in PWR type is about 1 ppm. Based on economic aspect and water requirements for reactor coolant system in PWR type, so co-generation of PWR and MED may be a favourable option for being applied in Muria Peninsula. (author)

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

    Outside the discussions relative to the advantages presented by the use of wood-energy from the point of view of the atmospheric pollution and global warming, another important aspect is the one of the economic interest presented by this wood. The agency for the environmental protection and the control of energy presents numerous useful elements to enlighten this question. The 'Bioresco' code is a tool that allows to evaluate the costs of investment and exploitation relative to a wood-energy installation. it can help at two levels: estimation of the costs of a project at the pre study level; checking of the costs of a project in the frame of a feasibility study realised by a thermal studies office, the software can alert on abnormally high costs. The 'Ecoprojet' code is a tool of economic analysis evaluating the profitability of the wood-energy solution face to a reference solution. It allows to calculate the economical analysis criteria from investment and exploitation costs of the biomass solution and of reference solution. The agency (A.D.E.M.E.) is bringing to a successful conclusion the following works: a study on the evolution of the investments costs relative to the collective wood-energy installations, works on economical analysis of typical cases studies. As illustration, a document of the A.D.E.M.E. is presented on the economic analysis of a wood-energy project. (N.C.)

  2. Economic Aspects of Load Following in Flexible Operation. Annex IV

    International Nuclear Information System (INIS)

    2018-01-01

    To supplement this publication, the IAEA has prepared an economic study to quantify the cost–revenue aspects for nuclear power plant operations in mixed energy systems, including flexible operation. The purpose of this study was to explore economic opportunities for using nuclear energy in future power markets with increasing deployment of renewable energy, specifically investigating the following: — How much power ramping could future reactors support and at what penalty? — What type of flexibility is required on the grid — larger down power and faster ramp rate for load following or increased start/stop capability? What is the optimal level of flexible capacity in a system? — How can nuclear energy be used in different grid environments (e.g. different sizes or complexities) to cope with variable power demand and fluctuating supply from renewable energy sources? — What are the economic implications (including different revenue streams) for using large reactors? — How do market regulation and real market interaction affect the economic viability of using nuclear power under the various system modes? To answer these questions, an analytical case study approach, which directly assesses the difference between energy specific production costs for a baseload nuclear system and a load following nuclear system, was selected. Such a study, based on a large scale country level power plant dispatching model, could assess the difference between the total short term costs of producing a given amount of electricity by both types of operation in a particular system. This approach may answer the questions of whether adding flexible nuclear operation to the power system is capable of generating overall system benefits by minimizing total system costs at different levels. This annex briefly summarizes the IAEA study, together with insights from the available sources, and underlines the pressing needs in filling the missing knowledge gaps in the economic aspects of

    1989-01-01

    This paper discusses how a broad spectrum of heat-generating nuclear waste types like reprocessing waste (HLW, ILW), spent LWR, and spent HTR fuel will be disposed of in a future German repository located in a salt dome. Different package and emplacement concepts for the various waste forms are feasible, ranging from pure borehole emplacement of canisters and drums to pure drift emplacement of heavily shielded casks as well as combinations of both concepts. Optimization of the whole back-end system (waste treatment, interim storage, and disposal) is performed taking into account thermal, operational, and economic aspects. From a radiological viewpoint, the drift emplacement concept is superior to all concepts in as much as the occupational dose is lowest and zero release from the casks is attainable during normal and anomalous repository operation. As far as economics are concerned, the cost of the heavily shielded casks necessary for drift emplacement contributes markedly to the overall cost of the whole back-end system. Drift emplacement can compete economically with the other concepts only if the casks are used both for interim storage and disposal

    2017-01-01

    The incidence of esophageal carcinoma has increased in recent years in Germany. The aim of this article is a discussion of the economic aspects of oncological esophageal surgery within the German diagnosis-related groups (DRG) system focusing on the association between minimum caseload requirements and outcome quality as well as costs. The margins for the DRG classification G03A are low and quickly exhausted if complications determine the postoperative course. A current study using nationwide German hospital discharge data proved a significant difference in hospital mortality between clinics with and without achieving the minimum caseload requirements for esophagectomy. Data from the USA clearly showed that besides patient-relevant parameters, the caseload of a surgeon is relevant for the cost of treatment. Such cost-related analyses do not exist in Germany at present. Scientific validation of reliable minimum caseload numbers for oncological esophagectomy is desirable in the future.

    International Nuclear Information System (INIS)

    2002-02-01

    The wind energy industry has demonstrated its maturity and technical reliability. Because it will play an increasing role on the power generation market, the question of the cost and profitability of the wind energy has become of prime importance. Two main traps must be avoided: the first should be to deny the present and future economical interest of wind energy because of its supplementary cost with respect to conventional power generation techniques. The second trap should be to underestimate the economical progresses that wind energy must carry on to ensure its large scale development. Therefore, some advantageous pricing and regulatory conditions are necessary to allow the development of this emerging energy source. This document presents: the cost of a wind power project (initial investment, financial incentives); the profitability of a project (cost of a kWh of wind power origin, retail price, warranty of power supply capacity, indirect environmental costs, value of decentralized production); economical interest of wind power (energy efficiency, employment, financial advantages for the local economy); and who are the investors.

    Injuries are one of the leading causes of death in the world. In Malaysia, injuries form one of the three main causes of mortality. They are also an important cause of permanent and temporary disability and work absenteeism in the productive age group. Increasing affluence and industrialization coupled with growing population and transportation needs in rapidly developing countries like Malaysia have resulted in a surge of road and occupational injuries. Three quarters of fatalities due to road, occupational, drowning and home injuries occur in those below 45 years of age. A majority of injuries in these categories are attributed to "human" factors and therefore can be prevented by public education and enforced training of workers. The total annual economic loss due to all types of injuries is estimated to be 2 billion Malaysian Ringgit (US$1 = MR2.76 approximately). The government is currently in the process of setting up full-time departments for road safety and occupational health and safety.

    Full Text Available The cyclicity of economic phenomena is not only their immanent property but also the subject of economic analysis. The modern way of making managerial decisions requires analysis of a number of cycles that fill any kind of activity. Accounting and reconciliation of construction, design, investment, purchasing, reproduction, leasing and other cycles is important for the investment and construction sector, both from the point of view of the need for their synchronization and from the position of determining trends in sectoral development. The analysis has showed that three main types of development are characteristic for investment and construction activity. Increasing intensity is inherent in a high level of cyclic synchronization. The degradation trend arises as a result of mismatched cycles. The stabilization character is inherent in the regular modes of maintaining the established proportions and cyclical inter-conformity. The study of the cyclical nature of investment and building processes is impossible without understanding their co-ordination. The principles of synchronization and subordination of the cycles should be used not only for the construction of cost-effective systems but also for the development of management tools.

We take into consideration the dual market on which mass-media evolves: the mass-media products market, and the advertising market, keeping in mind that the behavior of a mass-media institution on one market, can have direct implication on the other market. We analyze the relation between mass-media and the public (audience, the cost for creating mass-media products, the ways in which mass-media reduces costs and the ways of increasing their profits. As mass-media must always adapt to the social changes and to the public, we take our analysis further and we describe how the recent economic changes influenced the mass-media consumption trends and mass-media profits on all the main communication channels: TV, radio, outdoor, internet, newspapers/magazines. This analysis is performed at both a global and a local level, for Romania. In the end we predict how other key changes may affect the economic model approach of the mass-media institutions on short and middle terms.

  5. EMBIO - The Danish Energy Agency's model for economic and environmental evaluation of bio-fuels. Main report

    International Nuclear Information System (INIS)

    1997-01-01

    A methodological concept is established for a life-cycle based model which can be used for socio- and private economic and environmental assessment of automotive bio-fuels. The calculation method must be able to calculate socio-economic, energy, environmental, and other consequences by alternative productions and uses of bio-fuels in a way that makes it possible to compare advantages and disadvantages across alternative production technologies. Furthermore it must be possible to perform private cost-benefit calculations from the model. The model must also be able to evaluate specific bio-fuel project, and therefore the method has been developed in close interaction with analyses of two bio-fuel projects. The main emphasis in the development of the model has been put on the relation between CO 2 reduction and economics. One main result of the model analyses is therefore the calculated shadow price for the CO 2 reduction which expresses the socio-economic costs per ton saved CO 2 . The socio-economic analyses of the model do not include a monetary account of other environmental impacts than the CO 2 emission or other relevant consequences like impacts on employment, balance of payments etc. Thus the socio-economic analyses cannot be the only decision basis for assessing bio-fuel projects. The other environmental aspects are treated only briefly. The model may, however, very easily be extended to a more formalized account of these other aspects. The model may be used for specific experimental projects and for implementation of large full-scale projects. The model development has been limited to use of bio-fuels in the transportation sector. The model may, however, also be used for evaluating bio-fuels in general or other biomass-based energy use in other sectors. (LN) 113 refs

    The PSA Level 2 for Kozloduy NPP (KNPP) is an update of an older study with wider scope of analysis. The older study represented the status of the units up to 2001. The current PSA Level 2 is based on the PSA Level 1 and represents the status of the units up to 2007 year concerning the systems and procedures included in PSA level 1 and status up to 2011 for the systems and procedures (e.g. SAMG) related to containment and severe accident aspects. The study is performed after the PSA level 1 has been finished and approved by the customer. Compare to the older analysis all modes of operation for analyzed in PSA level 1 event groups as well Spent Fuel Pool accidents are investigated. The analysis consists of both deterministic and probabilistic analysis. As part of deterministic analysis a contemporary containment strength analysis and accident progression deterministic analysis using last version of MELCOR are performed. The probabilistic analysis contains of two part: Interface PSA and CET are calculated using Riskspectrum program code. Two types of models for CET have been developed: one for conditional probabilities calculations and a set of simplified CET's for each PDS group-for integral model. The purpose of the first model is to be able to perform quick calculations and for sensitivity analyses as well. The simplified CET's are used for integral calculation of the model. Source Term analysis is mainly based on the MELCOR analyses results. All characteristics of the releases have been defined, i.e. location, mass, energy of radionuclide groups and activity of the released isotopes (most important are reported only). The main goals of the study are to analyze the status of the containment, systems designed to prevent containment failure and operator action required under the severe accident and to give quantitative assessment of the risk parameter LERF (Large Early Release Frequency). This report will present main aspects, results, finding and

    1993-01-01

    In this report the experience gained in seismic re-evaluation of an old NPP (Trino Vercellese) is described. This PWR plant was not seismically designed. The main purpose of the upgrading, from the point of view of the Italian Directorate for Nuclear Safety - ENEA/DISP, was to have guaranteed the plant capability of achieving and maintaining a safe cold shutdown condition after a SSE seismic event. The main steps of the seismic review are discussed: definition of the new input motion; selection of structures, systems and components essential for a safe cold shutdown; definition of Codes and evaluation methods; seismic qualification of systems and components. Finally some modifications of a number of plant systems are described together with economical aspects. (author)

    Gitel'man, L.D.; Ratnikov, B.E.

    1992-01-01

    This article highlights the state of affairs regarding nuclear power in Russia at this time in the post-Chernobyl era. environmentalists and others are leveling criticisms at nuclear power stating that nuclear plants should be shutdown and preservation can offset the demands for electricity. The authors are advised to examine a new consensus for developing nuclear power, which could form the basis of a new program of social rehabilitation, and not a singular rejection of constructing new nuclear power plants. Public acceptance of nuclear power can be obtained only by resolving contradictions and by harmonizing the interests of all social groups and of all subjects of economic relationships, which in one way or another are connected to the financing and functioning of nuclear power plants (the local population, personnel, energy users, regional energy organizations, and local government). A strategy oriented to overall acceptance of nuclear power should consider intra area factors and also external economic environments: the choice of nuclear power plant location on the basis of careful and independent expertise with the use of rigid social-economic criteria and a sharp increase in the attention to human factors. Important features in changes in the economic environments are the transition to a marketplace economy, the reorientation of budget expenditures to social goals, and the expansion of regional economic independence. This requires a significant strengthening of the regional control of electrification and the creation of corresponding economic mechanisms

    Unsustainable fishing simplifies food chains and, as with aquaculture, can result in reliance on a few economically valuable species. This lack of diversity may increase risks of ecological and economic disruptions. Centuries of intense fishing have extirpated most apex predators in the Gulf of Maine (United States and Canada), effectively creating an American lobster (Homarus americanus) monoculture. Over the past 20 years, the economic diversity of marine resources harvested in Maine has declined by almost 70%. Today, over 80% of the value of Maine's fish and seafood landings is from highly abundant lobsters. Inflation-corrected income from lobsters in Maine has steadily increased by nearly 400% since 1985. Fisheries managers, policy makers, and fishers view this as a success. However, such lucrative monocultures increase the social and ecological consequences of future declines in lobsters. In southern New England, disease and stresses related to increases in ocean temperature resulted in more than a 70% decline in lobster abundance, prompting managers to propose closing that fishery. A similar collapse in Maine could fundamentally disrupt the social and economic foundation of its coast. We suggest the current success of Maine's lobster fishery is a gilded trap. Gilded traps are a type of social trap in which collective actions resulting from economically attractive opportunities outweigh concerns over associated social and ecological risks or consequences. Large financial gain creates a strong reinforcing feedback that deepens the trap. Avoiding or escaping gilded traps requires managing for increased biological and economic diversity. This is difficult to do prior to a crisis while financial incentives for maintaining the status quo are large. The long-term challenge is to shift fisheries management away from single species toward integrated social-ecological approaches that diversify local ecosystems, societies, and economies. ©2011 Society for Conservation

    2017-12-01

    Full Text Available The article investigates the interaction of the forms of network integration and the development of complimentary production networks in terms of economic security. Currently, the most developed countries are occurring a transition from the industrial society to the information society. The industry 4.0 as the continuous communication at all levels and characterizes the production processes, in which technologies and devices interact automatically in the value-added chain. Under these new conditions, the former types of organizational structures of economic entities are not sufficiently effective. Therefore, there is a need to create new, modern types of organizational structures. One of these types is network structures. Currently, they are becoming characteristic features of the new economy. Regional economic security depends on internal and external threats, which lead to unstable situations. Regional crisis situations are influenced by both macroeconomic crisis processes and local features of economic and social development, as well as the resource potential, geographical location, national and other peculiarities. The article defines the specific characteristics of the regions of the Ural Federal District, as well as the current situation of the regional economy and threats to the region. The authors have evaluated the economic security of complimentary production networks at the regional level. This evaluation has revealed the interconnection between complimentary production networks and the construction industry in the national economy. We have defined the economic security of complimentary production networks and specified the concept of complimentary production networks. The research findings may be applied by organizations as a new perspective of industry using network forms related to economic security

TRAB-3D/SMABRE Calculation of the OECD/ NRC PWR MSLB Benchmark

    2001-01-01

    All three exercises of the OECD/NRC Pressurized Water Reactor (PWR) Main-Steam-Line-Break (MSLB) Benchmark were calculated at VTT Energy. The SMABRE thermal-hydraulics code was used for the first exercise, the plant simulation with point-kinetics neutronics. The second exercise was calculated with the TRAB-3D three-dimensional reactor dynamics code. The third exercise was calculated with the combination TRAB-3D/SMABRE. Both codes have been developed at VTT Energy. The results of all the exercises agree reasonably well with those of the other participants; thus, instead of reporting the results, this paper concentrates on describing the computational aspects of the calculation with the foregoing codes and on some observations of the sensitivity of the results. In the TRAB-3D neutron kinetics, the two-group diffusion equations are solved in homogenized fuel assembly geometry with an efficient two-level nodal method. The point of the two-level iteration scheme is that only one unknown variable per node, the average neutron flux, is calculated during the inner iteration. The nodal flux shapes and cross sections are recalculated only once in the outer iteration loop. The TRAB-3D core model includes also parallel one-dimensional channel hydraulics with detailed fuel models. Advanced implicit time discretization methods are used in all submodels. SMABRE is a fast-running five-equation model completed by a drift-flux model, with a time discretization based on a non-iterative semi-implicit algorithm. For the third exercise of the benchmark, the TMI-1 models of TRAB-3D and SMABRE were coupled. This was the first time these codes were coupled together. However, similar coupling of the HEXTRAN and SMABRE codes has been shown to be stable and efficient, when used in safety analyses of Finnish and foreign VVER-type reactors. The coupling used between the two codes is called a parallel coupling. SMABRE solves the thermal hydraulics both in the cooling circuit and in the core

    A comprehensive analysis of a double-ended main-steam-line-break (MSLB) accident assumed to have occurred in the Babcock and Wilcox Three Mile Island (TMI) Unit 1 nuclear power plant (NPP) has been carried out at the Dipartimento di Ingegneria Meccanica, Nucleare e della Produzione of the University of Pisa, Italy. The research has been carried out in cooperation with the University of Zagreb, Croatia, and with partial financial support from the European Union through a grant to one of the authors. The overall activity has been completed within the framework of the participation in the Organization for Economic Cooperation and Development Committee on the Safety of Nuclear Installations-Nuclear Science Committee PWR MSLB Benchmark. Different code versions have been adopted in the analysis. Results from the following codes (or code versions) are described in this paper: 1. RELAP5/mod 3.2.2, gamma version, coupled with the three-dimensional (3-D) neutron kinetics PARCS code; 2. RELAP5/mod 3.2.2, gamma version, coupled with the 3-D neutron kinetics QUABBOX code; 3. RELAP5/3D code coupled with the 3-D neutron kinetics NESTLE code. Boundary and initial conditions of the system, including those relevant to the fuel status, have been supplied by The Pennsylvania State University in cooperation with GPU Nuclear (the utility, owner of TMI) and the U.S. Nuclear Regulatory Commission (NRC). The main challenge for the calculation was the prediction of the return to power (RTP) following the inlet of cold water into the core and one 'stuck-withdrawn' control rod. Non-realistic assumptions were proposed to augment the core power peak following scram. Zero-dimensional neutronics codes were capable of detecting the RTP after scram. However, the application of 3-D neutronics codes to the same scenario allowed the calculation of a similar value for overall core power peak but showed power increase occurrence in about one-tenth of the core volume. The results achieved in phase 1 of

    Durand-Zaleski, I

    2008-04-01

    Deciding on a health policy in practice means dedicating human and financial resources and prioritising spendings. The economic evaluation of prevention strategies attempts to establish a relationship between the medical benefit of prevention and its additional cost (or in some cases cost reduction) compared to no prevention. Decisions on reimbursing drugs, interventions or funding health programmes do not usually follow efficiency criteria which define economic rationality. Politics may for example decide to make prostate cancer a public health priority if mortality in a country or in some regions of the country appears to be excessively high. Economic rationality alone is not an appropriate factor on which to base a decision which may be purely political, reflecting the actual values of the society at a given point in time.

    2016-05-01

    Full Text Available This paper discusses a key contemporary problem, that of inequality. Certainly, the most visible inequality today is economic inequality, which is not only a characteristic found today, but is also the result of a long historical development. The problem arises when inequality becomes artificial (produces itself and thus becomes a matter of social sciences and humanities. At this point, the question of economic inequality becomes a non-economic issue and thus opens the possibility of formulating such principles that will be able to reduce the issue to a minimum. This paper discusses this possibility, while referring to Thomas Piketty’s book on capital in relation to John Rawls’s principles of justice to which Piketty refers to.

    The paper contains estimations of dependences of technical and economic characteristics of VVER-1000 fuel cycle on number of charged FAs and their enrichment. In the study following restrictions were used: minimum quantity of loaded fresh FAs is equal 36 FAs, a maximum one - 78 (79) FAs and fuel enrichment is limited by value 4,95 %. The following technical and economic characteristics are discussed: cycle length, average burnup of spent fuel, specific consumption of natural uranium, specific quantity of separative work, annual production of thermal energy, fuel component of electrical energy cost, electricity generation cost. Results of estimations are presented as dependences of researched characteristics on cycle length, quantity of loaded FAs and their enrichments. The presented information allows to show tendencies and ranges of technical and economic characteristics at change of fuel cycle parameters. This information can be useful for definition of the fuel cycle parameters which satisfy the requirements of power system and exploiting organizations. (authors)

    Construction industry has moved forward into a technology driven where a transition is in progress from conventional method to a more advanced and mechanised system known as the Industrialised Building System (IBS). However, the need to implement the IBS should be well understood by all construction players such as designer, architect, contraction, erectors and construction workers. Therefore, there is a need to educate all these construction players which should be spearheaded by authorities such as Construction Industrial Development Board where enforcement trough building by laws as well as initiative to those that adopt the IBS in their construction. This paper reports on economic aspects of using interlocking hollow brick system in construction as an alternative method offered for Industrialized Building System. The main objective is to address the economic aspects of using interlocking block system in terms of time, costs, and utilization of manpower and to present some of the experimental tests results related to Interlocking Hollow Brick System (IHBS). Example of savings from the use of IHBS is presented in this paper by comparing the construction of two storey terrace house with build-up area of about 200 square meter with conventional construction method of typical reinforced concrete construction (RCC) compared to IHBS. The comparison shows that the implementation of IHBS can reduce construction time, cost, and utilization of man power up to 26.6% compared to the conventional method. Moreover, the construction time using IHBS can also be reduced by up to 50% as compared to the conventional construction.

    2013-06-01

    Full Text Available This study focuses on the global financial-economic crisis and the main priorities of the European Union for 2020. The duration of a financial economic crisis depends on the macroeconomic factors taken into account, because their representation can have multiple nuances, generated by subjective and political influences. The financial and economic crisis had a significant impact on public finances, business, jobs and families. At all levels, the decision makers in public policy will have to find ways of triggering economic dynamism, while the margin of manoeuvre in what concerns the budget is limited. As the recorded deficit in the public sector will be again under control, public expenditure will be such organized that the targets for 2020 are met.

    2009-04-01

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

  8. Socio-economic aspects of different biofuel development pathways

    International Nuclear Information System (INIS)

    Duer, Henrik; Christensen, Pernille Ovre

    2010-01-01

    There are several policy drivers for biofuels on a larger scale in the EU transport sector, including increased security of energy supply, reduced emission of greenhouse gases (GHG), and new markets for the agricultural sector. The purpose of this socio-economic cost analysis is to provide an overview of the costs of meeting EU biofuels targets, taking into account several external costs and benefits. Biofuels are generally more expensive than traditional fossil fuels, but the expected increasing value of GHG emission reductions will over time reduce the cost gap. High crude oil prices significantly improve the economic benefit of biofuels, but increased demand for biomass for energy purposes is likely to increase the price of biofuels feedstock and biofuels costs. The key question is to what extent increasing oil prices will be passed on to biofuels costs. Socio-economic least costs for biofuels production require a market with a clear pricing of GHG emissions to ensure that this factor is included in the decision-making of actors in all links of the fuel chain.

  9. Economic aspects of electricity and industrial heat generating reactors

    Gaussens, J.; Moulle, N.; Dutheil, F.

    1964-01-01

    The economic advantage of electricity-generating nuclear stations decreases when their size decreases. However, when a counter-pressure turbine is joined on to a reactor and the residual heat can be properly used, it can be shown that fairly low capacity nuclear equipment may compete with conventional equipment under certain realistic enough conditions. The aim of this paper is to define these special conditions under which nuclear energy can be profitable. They are connected with the location and the general economic environment of the station, the pattern of the electricity and heat demands it must meet, the level of fuel and specific capital costs, nuclear and conventional. These conditions entail certain technical and economic specifications for the reactors used in this way otherwise they are unlikely to be competitive. In addition, these results are referred to the potential steam and electricity market, which leads us to examine certain uses for the heat generated by double purpose power stations; for example, to supply combined industrial plants, various types of town heating and for removal of salt from sea water.

    To estimate the societal economic and health impacts of Maine's school-based influenza vaccination (SIV) program during the 2009 A(H1N1) influenza pandemic. Primary and secondary data covering the 2008-09 and 2009-10 influenza seasons. We estimated weekly monovalent influenza vaccine uptake in Maine and 15 other states, using difference-in-difference-in-differences analysis to assess the program's impact on immunization among six age groups. We also developed a health and economic Markov microsimulation model and conducted Monte Carlo sensitivity analysis. We used national survey data to estimate the impact of the SIV program on vaccine coverage. We used primary data and published studies to develop the microsimulation model. The program was associated with higher immunization among children and lower immunization among adults aged 18-49 years and 65 and older. The program prevented 4,600 influenza infections and generated $4.9 million in net economic benefits. Cost savings from lower adult vaccination accounted for 54 percent of the economic gain. Economic benefits were positive in 98 percent of Monte Carlo simulations. SIV may be a cost-beneficial approach to increase immunization during pandemics, but programs should be designed to prevent lower immunization among nontargeted groups. © Health Research and Educational Trust.

    1983-01-01

    Increases in the price of such conventional fuels as Diesel No. 2, as well as advancements in turbine technology, have prompted the present economic assessment of coal-fired gas turbine locomotive engines. A regenerative open cycle internal combustion gas turbine engine may be used, given the development of ceramic hot section components. Otherwise, an external combustion gas turbine engine appears attractive, since although its thermal efficiency is lower than that of a Diesel engine, its fuel is far less expensive. Attention is given to such a powerplant which will use a fluidized bed coal combustor. A life cycle cost analysis yields figures that are approximately half those typical of present locomotive engines.

    The quantity of usable fission products which will be obtained by nuclear fission till the year 2000 is estimated on the basis of prognostics for the development of nuclear energy in the world considering especially the development in the U.S.S.R. and the CMEA. The possibilities of utilization of cesium as gamma-ray source are discussed, and the present fields of application of palladium and the development of its price on the world market are shown. The fields of application of technetium, which wasn't available as artificial element in a greater quantity till now, have to be developed. The economic estimations base on data of a project for the separation of fission products in connection with a reprocessing plant, which was developed in the U.S.A. in 1978. The data show, that it is possible to produce the platinum metals and cesium with profit, the same can be expected for technetium. (author)

This was even more the case for original institutionalist thinkers such as Thorstein Veblen, John Commons, and Clarence Ayres. In their writings, direct interdependence, interactions (or transactions among agents, with all beneficial and with all problematic consequences, took center stage in economic analysis. Why, for instance, do people adhere to a particular new fashion or trend? Because others do, after eminent people, wealthy people, the “leisure class” (T. Veblen, have made it a symbol for status. The new fashion, however, ceases to serve as such a symbol once too many people follow it. The constant effort put into following trends and adopting fashion turns out to be a social dilemma, driven by Veblenian instincts, such as invidious distinction in predatory societies, conspicuous consumption and emulation.

    A few introductory remarks on the status of and on prospects fo the world energy economy as well as on reasons given for the necessity of a world-wide coordination of energy policy and economic policy are followed by an explanation of the policy led by oil extracting countries and of the endeavour of western industrialized countries to reduce oil imports. Even if the state of utilizing nuclear energy does not yet present a sufficient alternative, the international nuclear energy continues to be directed towards this goal. Seen from an international viewpoint, relieving contributions are to be expected from energy-conservation-actions and from the development of regenerative energy sources. (UA) [de

The amount of remittances depends on the income of both the migrants and their family members.... Remittances meant for investment at home are determined by interest rates, foreign exchange regulations, exchange rates, monetary stability etc. in the immigration and emigration countries. Home remittances and saving habits of emigrants also depend on whether or not they expect to return to their home countries and the prospects of family reunification, all of which is directly linked to the (immigration) policy and economic conditions of both the countries of origin and residence."

These studies were carried out by Interatom (today Siemens/KWU) in Bergisch Gladbach, Flachglas Solartechnik in Koln and Schlaich Bergermann and Partner in Stuggart under contract of DLR in Koln. Funds were made available by the German Ministry of Research and Development (BMFT). The results indicate that all of the investigated technologies have the potential to reduce the generating costs and that in the future costs of below 0.30 DM/kWh could be expected under excellent insolation conditions (e.G. 2850 kWh/m''2 a direct insolation as in California/USA).

  2. Aspects of Development Financing After the Financial and Economic Crisis

    2011-05-01

    Full Text Available Published by Palgrave MacmillanThe financial and economic crisis saw developing and emerging countries experience more severe setbacks in their growth rates than industrialised countries and they did not all have sufficient funds to finance robust stimulus measures. The major emerging economies have nevertheless recovered quickly and are currently the most important growth engines in the world economy.Private capital flows collapsed, leaving the global South with an overall deficit in financing. Greater official financing flows have not yet been able to compensate for the shortfalls and the slow increase in private capital flows since the end of 2009 has not been able to do so either. Overall, according to the UN, more capital flows from the South to the North than vice versa. The South thus continues to finance the North.Discussions regarding a reform of the global financial and economic order are ongoing but to date have had little impact on developing countries. The international financing institutions do have more funds at their disposal, but developing countries are still under-represented. The IMF and the World Bank have begun to question some of their previous dogmas. Opinions are divided on whether one can already speak of a new policy.The debate on the role of taxation in the mobilisation of local resources for development financing has intensified. Insight favouring comprehensive reforms of the taxation systems in developing countries has sharpened, but technical aid provided by industrialised countries to realise these reforms is still insufficient. Taxation is acquiring growing recognition as an instrument of State-building, democratisation and governance. The campaign to deal with international tax evasion and illicit capital flows is gaining momentum and the exchange of information on tax issues has improved. However, it is difficult to establish newer and more trenchant instruments for improved transparency, given the predominant

  3. The economic aspects of artificial snow production in the perspective of climate change

    Gonseth, C.

    2012-04-01

    Snowmaking is now used by ski resorts worldwide as a measure to cope with both natural snow reduction and variability. This extensive recourse casts doubt on its sustainability mainly because of the large amount of natural resources being used (energy, water). In the middle to long run, this problem is expected to increase with future climate change triggering the production of more snow. The research field that focuses on the economic aspects of artificial snow production is still in its infancy but potentially covers a wide array of issues. Among these issues, benefits and costs of snowmaking are important ones. On the one hand, benefits arise as snowmaking extends or preserves the operating period of ski areas. Several empirical studies speculate or show that snowmaking considerably reduces the sensitivity of tourism consumption to variations in snow conditions. These benefits have long been neglected in studies analyzing the consequences of climate change for the winter tourism sector. While failing to introduce these benefits, many studies have generated overly high costs of climate change. On the other hand, investments and operating costs of artificial snow production depend upon several factors, such as technology and local conditions. Consequently, costs vary considerably from one location to another and over time, yet indicative values can be found in the literature. In addition, artificial snow production generates external costs, i.e. costs that are not born by those producing it. Typical of these external costs are environmental ones that are related to CO2 emissions or biodiversity losses. To our knowledge, very little has been done so far to integrate these costs in economic studies. To the extent that vertical integration is absent, it may happen as well that snow production generates important external benefits for different stakeholders at a given ski resort. From an economic point of view, both types of externalities could lead to investment

Three major views are considered, namely the classical one, the Keynesian one and the view of neoliberal economists (monetarist economists and representatives of the school of rational expectations. The comparative approach of the different views allowed us to shape some criteria of decision which may prove useful for public policymakers in formulating public debt policies conducive to economic growth: public indebtedness should not become common practice but be reserved for those situations in which the economy is confronted with unusual phenomena, such as economic downturns; borrowed resources should be used especially on those destinations which create added value in the economy, such as public investment; public debt should not accumulate at a fast pace and should be kept within reasonable limits, to avoid possible side effects on economic growth.

    Intensive groundwater development is a common circumstance in semiarid and arid areas. Often abstraction exceeds recharge, thus continuously depleting reserves. There is groundwater mining when the recovery of aquifer reserves needs more than 50years. The MASE project has been carried out to compile what is known about Spain and specifically about the south-eastern Iberian Peninsula and the Canary Islands. The objective was the synthetic analysis of available data on the hydrological, economic, managerial, social, and ethical aspects of groundwater mining. Since the mid-20th century, intensive use of groundwater in south-eastern Spain allowed extending and securing the areas with traditional surface water irrigation of cash crops and their extension to former dry lands, taking advantage of good soils and climate. This fostered a huge economic and social development. Intensive agriculture is a main activity, although tourism plays currently an increasing economic role in the coasts. Many aquifers are relatively high yielding small carbonate units where the total groundwater level drawdown may currently exceed 300m. Groundwater storage depletion is estimated about 15km(3). This volume is close to the total contribution of the Tagus-Segura water transfer, but without large investments paid for with public funds. Seawater desalination complements urban supply and part of cash crop cultivation. Reclaimed urban waste water is used for irrigation. Groundwater mining produces benefits but associated to sometimes serious economic, administrative, legal and environmental problems. The use of an exhaustible vital resource raises ethical concerns. It cannot continue under the current legal conditions. A progressive change of water use paradigm is the way out, but this is not in the mind of most water managers and politicians. The positive and negative results observed in south-eastern Spain may help to analyse other areas under similar hydrogeological conditions in a less

  8. Economic aspects and potentials of renewable energy sources in Germany

    International Nuclear Information System (INIS)

    Mannsbart, W.; Reichert, J.

    1992-01-01

    While there is a high theoretical potential for renewable energy sources in Germany, assessing theoretical potentials is more or less like playing with numbers; severe technical shortcomings and economic factors prevent then from being fully achieved. Unsuitable azimuth and slope of roofs, shading, absence of central hot water systems limit the application of collectors. The present storage technology is not suitable for a solar share higher than 50%. Individual space heating is not feasible under local climatic conditions. The broad application of biomass fuels fails because of limited resources. Feeding high amounts of fluctuating electricity generated by wind and photovoltaic systems into utility grids causes stability and storage problems. Insufficient training of installation personnel, lack of incentives for multi-family housing owners and high investment costs hinder the market penetration of renewable energy sources. Drastic cost reductions can only be expected from mass production. Therefore, appropriate policy measures - raised energy prices, as well as, subsidies or tax reliefs are necessary for market breakthrough

    The use of renewable energy for the continuously growing global population is becoming increasingly important. These forms of energy not only broaden the urgently needed resource base, but are also free from emission of CO{sub 2}, SO{sub 2}, NO{sub x} etc. The Federal German Government early recognized this and has provided more than DEM 4000 million for this purpose since 1973. Together with Japan and the USA, Germany belongs to the three leading nations in the world in R and D on the application of renewable energy. It has by far the largest and most broadly based programme in Europe. The technical and economical progress of wind power is very promising in Germany.

    The use of renewable energy for the continuously growing global population is becoming increasingly important. These forms of energy not only broaden the urgently needed resource base, but are also free from emission of CO{sub 2}, SO{sub 2}, NO{sub x} etc. The Federal German Government early recognized this and has provided more than DEM 4000 million for this purpose since 1973. Together with Japan and the USA, Germany belongs to the three leading nations in the world in R and D on the application of renewable energy. It has by far the largest and most broadly based programme in Europe. The technical and economical progress of wind power is very promising in Germany.

    More than 40 % of the forests in Siberia region are known to have a fire danger of high classes and high burning degrees. This paper describes air pollutants emission (PM10, nitrogen oxides, sulfur dioxide and others) in East Siberian region during a 10-year period in the forests fires focus. A total of 500 to 2000 fires occurred in Irkutsk oblast during the last ten years. At an average annual forest fires cover an area of 1 109 hectares on the model territory (Bratsk city). The plane pollutant emission source with a high productivity is formed on the significant forest fire area occurred in a relatively short-term time periods. The increase in hazard ratios was registered for the ingredients of emission-specific industrial enterprises and capable of accumulating in vegetation: carbon disulphide 1.9 times, fluorine-containing substances 1.8 times during the fire. The economic loss of energy resources resulting from reduced production of firewood was estimated at 56.6 million in Irkutsk oblast. The potential risk of negative effects for the respiratory system and cardiovascular system stipulated for the acute inhalation exposure was found to increase on the days, of the fires, as evidenced by the growth of the daily mortality and morbidity rates among the population.

    2018-02-12

    This report provides information for decision-makers about floating offshore wind technologies in the state of Maine. It summarizes research efforts performed at the National Renewable Energy Laboratory between 2015 and 2017 to analyze the resource potential, cost of offshore wind, and economic potential of offshore wind from four primary reports: Musial et al. (2016); Beiter et al. (2016, 2017); and Mone et al. (unpublished). From Musial et al. (2016), Maine's technical offshore wind resource potential ranked seventh in the nation overall with more than 411 terawatt-hours/year of offshore resource generating potential. Although 90% of this wind resource is greater than 9.0-meters-per-second average velocity, most of the resource is over deep water, where floating wind technology is needed. Levelized cost of energy and levelized avoided cost of energy were computed to estimate the unsubsidized 'economic potential' for Maine in the year 2027 (Beiter et al. 2016, 2017). The studies found that Maine may have 65 gigawatts of economic potential by 2027, the highest of any U.S. state. Bottom-line costs for the Aqua Ventus project, which is part of the U.S. Department of Energy's Advanced Technology Demonstration project, were released from a proprietary report written by NREL in 2016 for the University of Maine (Mone et al. unpublished). The report findings were that economies of scale and new technology advancements lowered the cost from $300/megawatt-hour (MWh) for the two-turbine 12-megawatt (MW) Aqua Ventus 1 project, to $126/MWh for the commercial-scale, 498-MW Aqua Ventus-2 project. Further cost reductions to $77/MWh were found when new technology advancements were applied for the 1,000-MW Aqua Ventus-3 project in 2030. No new analysis was conducted for this report.

    Full Text Available The geographical regions contiguous to the Indian Ocean, Bay of Bengal and the Arabian Sea are prone to natural disasters and poor electric supply especially in rural and hard to reach coastal regions. Utilization of ocean resources for power generation such as tidal, thermal solar and wind for energy need to be incorporated in a broad framework for the region. Development of ocean-based energy systems can be integrated with early warning networks linked by satellite which can give a few hours to days warning to help mitigate the severity of natural disasters on human life. Ocean-based electricity extraction has; however, remained elusive for various reasons. Interest in these systems resumed after the oil crisis of the 1970’s, but was uncoordinated. Extraction of ocean energy from the kinetic energy of waves and ocean currents depends on various mechanical devices with variable efficiencies. Apart from the efficiency, one must match the output phase of the feeder waveforms with that of the electrical grid. Also, the wavelengths of the typical wave are of the order of a few meters, the interception of which requires large devices. The mechanical efficiency of the turbine extraction system is further limited by the flow momentum considerations. Some applications and their implementation are looked at, specifically with reference to the difficulties of implementation in the region, and other factors like economic efficiency (rate of returns in place of mechanical efficiency. Individual wave energy harvesters are thus bound to suffer from inefficiencies and it may be beneficial to use wave farm configurations from the point of view of the randomness of wave motion, the large wavelengths, and the added advantage of averaging fluctuations from large numbers of generators.

    Nuclear power plants may be decommissioned by one of three primary methods - mothballing, entombing, or dismantling, or by using combinations such as mothballing or entombing for a period of time followed by dismantling. Mothballing or entombing both result in an end-product which requires surveillance and maintenance for a significant period to ensure protection of public health and safety. This paper discusses costs for each of the decommissioning methods, including factors that will influence the method selected as well as the total costs. Decommissioning costs have been estimated for an 1100-MW(e) light-water reactor within one year after shutdown following forty years of operation. The basic economic parameters for each decommissioning method were developed using unit cost factors based on known costs of previously decommissioned reactors. Decommissioning cost estimates range from less than four million dollars for mothballing to about forty million dollars for complete dismantling. Estimated cost of entombment is about ten million dollars. Subsequent annual cost of surveillance and maintenance for a reactor facility using the mothballing or entombment method could be as high as US $200,000. Although some tooling development will be needed for removing highly activated reactor vessel segments and internals, technology is currently available and has been demonstrated on prior decommissionings, e.g. the BONUS and HALLUM reactor entombments and the Elk River Reactor complete dismantling. Costs associated with decommissioning are significant; however, allowance for them either as a one-time construction period sinking fund, or annual depreciation type operating allowance, will have little effect on construction or on operating costs.

    Satisfaction of energy demand in the country especially that of electrical power will depend not only on finding resources but also on appropriate technological choices. As is well known, the supply of electricity itself induces demand. Thus, a scenario of growth of demand chasing the growth of supply will continue for many more years to come. Though conservation measures and increasing share of non-conventional energy supply have their part, coal and hydro based power will have to play the main role in increasing electricity demand in the country. To meet peaking power requirements, regional and national grid would have to use hydro capacity. This would also allow thermal sets to operate at higher PLF. New and upgraded technologies like fluidized bed combustion, coal gasification, gas turbine based combined cycle, power system automation and a number of others in allied fields will be pursued strongly

    2015-10-01

    Research and development work for about one decade have demonstrated many unique thermal spray coating properties, particularly for oxide ceramic coatings by using suspensions of fine powders as feedstock in APS and HVOF processes. Some particular advantages are direct feeding of fine nano- and submicron-scale particles avoiding special feedstock powder preparation, ability to produce coating thicknesses ranging from 10 to 50 µm, homogeneous microstructure with less anisotropy and lower surface roughness compared to conventional coatings, possibility of retention of the initial crystalline phases, and others. This paper discusses the main aspects of thermal spraying with suspensions which have been taken into account in order to produce these coatings on an economical way. The economic efficiency of the process depends on the availability of suitable additional system components (suspension feeder, injectors), on the development and handling of stable suspensions, as well as on the high process stability for acceptance at industrial scale. Special focus is made on the development and processability of highly concentrated water-based suspensions. While costs and operational safety clearly speak for use of water as a liquid media for preparing suspensions on an industrial scale, its use is often critically discussed due to the required higher heat input during spraying compared to alcoholic suspensions.

    The code DYN3D coupled with ATHLET was used for the analysis of the OECD Main-Steam-Line-Break (MSLB) Benchmark, which is based on real plant design and operational data of the TMI-1 pressurized water reactor (PWR). Like the codes RELAP or TRAC,ATHLET is a thermal-hydraulic system code with point or one-dimensional neutron kinetic models. ATHLET, developed by the Gesellschaft for Anlagen- und Reaktorsicherheit, is widely used in Germany for safety analyses of nuclear power plants. DYN3D consists of three-dimensional nodal kinetic models and a thermal-hydraulic part with parallel coolant channels of the reactor core. DYN3D was coupled with ATHLET for analyzing more complex transients with interactions between coolant flow conditions and core behavior. It can be applied to the whole spectrum of operational transients and accidents, from small and intermediate leaks to large breaks of coolant loops or steam lines at PWRs and boiling water reactors. The so-called external coupling is used for the benchmark, where the thermal hydraulics is split into two parts: DYN3D describes the thermal hydraulics of the core, while ATHLET models the coolant system. Three exercises of the benchmark were simulated: Exercise 1: point kinetics plant simulation (ATHLET) Exercise 2: coupled three-dimensional neutronics/core thermal-hydraulics evaluation of the core response for given core thermal-hydraulic boundary conditions (DYN3D) Exercise 3: best-estimate coupled core-plant transient analysis (DYN3D/ATHLET). Considering the best-estimate cases (scenarios 1 of exercises 2 and 3), the reactor does not reach criticality after the reactor trip. Defining more serious tests for the codes, the efficiency of the control rods was decreased (scenarios 2 of exercises 2 and 3) to obtain recriticality during the transient. Besides the standard simulation given by the specification, modifications are introduced for sensitivity studies. The results presented here show (a) the influence of a reduced

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

    Purpose: To evaluate the diagnostic and clinical relevance and therapeutic consequences of CT-guided biopsy with regard to economic aspects. Methods: 213 CT-guided biopsies in 190 were evaluated. All information regarding patient referral, reason for request, body region, underlying diagnosis, and clinical consequences were registered over a period of 22.2±9.4 month. Results: Patient referral to biopsy was mainly from the departments of surgery, internal medicine, and radiotherapy with the question of tumor and metastasis. Less than 5% of biopsies were performed in outpatients. Main regions were the lung (39%), the abdomen (35%), and the skeleton (11%). Biopsy and surgical histology corresponded in 73%. Largest diagnosis groups were benign unspecific tissues or other benign lesions in 24%. As a result of CTP no further procedures necessary in 22.5%. Follow-up studies or conservative treatment were indicated in 11.3%. Surgical procedures were needed in only 15.5%. There was only one complication requiring therapy. Conclusion: CT-guided biopsy is a safe procedure, which helps to avoid unnecessary cost-intensive diagnostics and surgical treatment. If CTP is performed early and in outpatients residence time in the hospital is reduced and thus money is saved. (orig.) [de

    The Sisters of Charity Health System, Lewiston, ME, a member of Covenant Health Systems, Lexington, MA, remains deeply committed to the mission of service begun by its foundress, St. Marguerite d'Youville. Although St. Marguerite experienced a hard life, her resilience and her commitment to the poor and disadvantaged serve as an inspiration to those who continue her legacy of compassionate care. The founding work of St. Marguerite and the sisters has helped to foster a culture in which the mission of service thrives among the system's 2,000 employees. This culture can be attributed to two things: the system's organizational values of compassion, stewardship, respect, and excellence; and the recognition of those employees whose work embodies these values. From the boardroom to the patient room, mission is integrated into each decision and action. Every two years, each of Covenant Health System's member facilities engages in a mission assessment process that examines various aspects of mission, including Catholic identity, holistic care, care for the poor, mission values integration, ethics and employee relations. In addition, the Sisters of Charity Health System's board has its own standing Mission and Community Committee, which looks strategically at how creatively and faithfully the system is continuing to live its mission.

    Full Text Available A soil and rock slope assessment survey was conducted along Bireun – Takengon main road in Aceh Province, Indonesia. The slope assessment survey was carried out to determine the geological condition, verify and identify the potential areas of slope failure and to study what type of slope stability and protection method could be applied to the road. Several research methodologies were conducted in the field such as rock and soil identification, and slope assessment. The survey was conducted in four selected areas along Bireun – Takengon main road. In study area I, soil creep occurred because of a presence of montmorillonite clay. The mitigation methods to reduce soil creeping in this area are building a retaining wall and pile. The shotcrete, wire mesh, net rock bolting, and rock removal method is suitable to apply in study area II. The shotcrete and soil nails were used because the type of rocks in those areas is sedimentary rock such as shale, sandstone, siltstone, and a boulder of a volcanic rock. The same approach shall be applied in study area IV. study area III was the best spot to learn about the mitigation approach for slope stability and provides many lessons learned. Aceh Province experience active tectonic movement, high intensity of rain, geological structures, a high degree of weathering, and high intensity of earthquake,as primary factors which trigger landslides. The techonology of slope stabilizing and protection methods can be applied to mitigate landslides.

    The heavy transportation in Brazil is generally done by highways. The radioactive material transportation follow this same rule. Whenever a radioactive material is carried by the road, by the sea or by the air, in some cases, a kind of combination of those transportation ways, the transport manager has to create a Transportation Plan and submit it to CNEN. Only after CNEN's approval, the transportation can be done. The plan must have the main action on Radiation Protection, giving responsibilities and showing all the directing that will be take. Although, the Brazilian's highways are not in good conditions, one could say that some of them are not good enough for any kind of transportation. But we are facing radioactive material use increase but the hospitals and industries, that the reason it's much more common that kind of transportation nowadays. So, because of that, a special attention by the governments must be provide to those activities. This paper goal is to show the real conditions of some important highways in Brazil in a radioactive protection's perspective and give some suggestions to adjust some of those roads to this new reality.

    Full Text Available Non-Hodgkin's lymphoma (NHL consists of a group of neoplasias involving mainly B cells and represents 90% of all lymphomas. The current available therapy is based on chemotherapy associated with the monoclonal antibody rituximab (Mab Thera(r, which targets the CD20 protein, present in over 80% of NHL mature B cells. Recent clinical reports show a preference for combining the benefits of immunotherapy and adjuvant chemotherapy, thus generating safe and effective alternative treatments. The current review aimed at evaluating various aspects related to the use of rituximab for NHL, highlighting the possible inhibitory mechanisms of cell proliferation, the achieved clinical results, and the expected clinical and economic outcomes of treatments. The results from clinical tests indicate the need for a better understanding of the critical mechanisms of action of this antibody, which may maximize its therapeutic efficacy. This therapy not only represents a viable option to treat most types of NHLs, especially when associated with conventional chemotherapy, but also offers cost-utility and cost-effectiveness advantages.

    The basic strategy of Russian Nuclear Energy development is the formation of the closed fuel cycle based on fast breeder and thermal reactors, as well as the solution of problems of spent nuclear fuel accumulation and availability of resources. Three options of multiple Pu and U recycling in VVER reactors are considered in this work. Comparison of MOX and REMIX fuel recycling approaches for the closed fuel cycle involving thermal reactors is presented. REMIX fuel is supposed to be fabricated from non-separated mixture of uranium and plutonium obtained in spent fuel reprocessing with further makeup by enriched U. These options make it possible to recycle several times the total amount of Pu and U obtained from spent fuel. The main difference is the full or partial fuel loading of the core by assemblies with recycled Pu. The third option presents the concept of heterogeneous arrangement of fuel pins made of enriched uranium and MOX in one fuel assembly. It should be noted that fabrication of all fuel assemblies with Pu requires the use of expensive manufacturing technology. These three options of core loading can be balanced with respect to maximum Pu and U involvement in the fuel cycle. Various physical and economical aspects of Pu and U multiple recycling for selected options are considered in this work.

    Accurate predictions of fishery recruitment and landings represent an important goal of fisheries science and management, but linking environmental drivers of fish population dynamics to financial markets remains a challenge. A fundamental step in that process is understanding the environmental drivers of fishery recruitment. American lobster (Homarus americanus) populations of the northwest Atlantic have been undergoing a dramatic surge, mostly driven by increases the Gulf of Maine. Settler-recruit models that track cohorts after larvae settle to the sea bed are proving useful in predicting subsequent fishery recruitment some 5-7 years later. Here we describe new recruitment forecasting models for the lobster fishery at 11 management areas from Southern New England to Atlantic Canada. We use an annual survey of juvenile year-class strength and environmental indicators to parameterize growth and mortality terms in the model. As a consequence of a recent widespread multi-year downturn in larval settlement, our models suggest that the peak in lobster abundance in the Gulf of Maine will be passed in the near future. We also present initial steps in the coupling of forecast data with economic models for the fishery. We anticipate that these models will give stakeholders and policy makers time to consider their management choices for this most valuable of the region's fisheries. Our vision is to couple our forecast model outputs to an economic model that captures the dynamics of market forces in the New England and Canadian Maritime lobster fisheries. It will then be possible to estimate the financial status of the fishery several years in advance. This early warning system could mitigate the adverse effects of a fluctuating fishery on the coastal communities that are perilously dependent upon it.

  7. The economic impacts of desert power. Socio-economic aspects of an EUMENA renewable energy transition

    2013-06-15

    The countries of the Middle East and North Africa (MENA) are one of the world's largest potential growth markets for renewable energy generation. Countries throughout the region have recognized the great potential of their excellent wind and solar conditions, and ample empty space, and have ambitious plans to develop solar and wind energy. They are already making progress in realizing these renewables targets. They also increasingly recognize the great potential of renewable energy in tackling a range of challenges. At a time of high unemployment, particularly among youth, the growth of renewable energy provides an engine for creating new jobs and fostering new skill profiles among workers. Renewables can increase GDP and form the basis for a significant new source of trade revenues. As a source of energy, renewables reduce dependency on fossil fuels - whether as imports, to supply energy, or as exports. This report, Economic Impacts of Desert Power (EIDP), investigates how, and under what conditions, renewables in MENA can lead to socioeconomic benefits. EIDP shows, under various scenarios, how many jobs can be expected in three exemplary MENA countries, and how the expansion of renewables can lead to higher GDP growth rates across the region. EIDP pinpoints their economic impact across sectors and countries. At the same time, EIDP describes how these effects can be maximized through immediate and sustained policy support. The report also details how such support can be tailored to foster a self-sustaining market. In short, EIDP aims to contribute to a range of debates focused on how to maximize the benefits of green growth. EIDP illustrates the following points: - MENA can benefit economically from decarbonizing - even if the rest of the world does not pursue climate action. - Exporting excess electricity is an economic opportunity for MENA countries - several North African countries could create a major export industry with renewable electricity, which

    trade in goods and services, investment, distinguishing almost all agreements, as well as intellectual property rights, mobility of individuals and economic cooperation in the framework of some agreements. The article examines the state of trade and investment cooperation between partners in the free trade areas, and comes to the main conclusion about the effect of trade crea-tion, which is expressed in a faster rate of growth in mutual trade and a growth of its share. The greatest economic benefit for ASEAN is the free trade area with China due to such factors as the population size and GDP volume, geographical proximity, the volume of trade at the time of formation of the free trade area, the complementarity of economic structures, and the size of duty rates at the time of signing the agreement. Experience of the functioning of free trade zones within the framework of the ASEAN + 1 shows the importance of wider coverage of economic relations in the liberalization.

  9. Theoretical Aspects of Cross-border Integration-based Economic Cooperation

    Bilchak V.

    2014-09-01

    Full Text Available In this article the author analyses theoretical aspects of border economy in the conditions of modern processes of integration. The author describes the existing schools and concepts of integration stressing the role of government regulation relating to the deformations in the development of the world economic mechanism. Modern studies focus on the evolution of integration processes, which has largely affected the key elements of the world economic mechanism from classical political economy, monopoly regulation. This resulted in monopolistic competition, imperfect competition, and oligopoly – largely, through all fields and poles of economic growth to certain elements of government regulation and social reproduction on the international scale. The author examines the key elements and stages of economic integration. These stages assume a number of consecutive forms: free trade zone, customs union, common market, complete economic integration, and economic union. The article shows that the transition occurs from the lowest to the highest stages — from the processes of integration involving, firstly, trade market and then capital and labour markets to the integration of social sphere. The theoretical aspects of all these transformations can be easily traced in the case of EU integration processes.

    Recent pollinator declines highlight the importance of evaluating economic risk of agricultural systems heavily dependent on rented honey bees or native pollinators. Our study analyzed variability of native bees and honey bees, and the risks these pose to profitability of Maine's wild blueberry industry. We used cross-sectional data from organic, low-, medium-, and high-input wild blueberry producers in 1993, 1997-1998, 2005-2007, and from 2011 to 2015 (n = 162 fields). Data included native and honey bee densities (count/m2/min) and honey bee stocking densities (hives/ha). Blueberry fruit set, yield, and honey bee hive stocking density models were estimated. Fruit set is impacted about 1.6 times more by native bees than honey bees on a per bee basis. Fruit set significantly explained blueberry yield. Honey bee stocking density in fields predicted honey bee foraging densities. These three models were used in enterprise budgets for all four systems from on-farm surveys of 23 conventional and 12 organic producers (2012-2013). These budgets formed the basis of Monte Carlo simulations of production and profit. Stochastic dominance of net farm income (NFI) cumulative distribution functions revealed that if organic yields are high enough (2,345 kg/ha), organic systems are economically preferable to conventional systems. However, if organic yields are lower (724 kg/ha), it is riskier with higher variability of crop yield and NFI. Although medium-input systems are stochastically dominant with lower NFI variability compared with other conventional systems, the high-input system breaks even with the low-input system if honey bee hive rental prices triple in the future. © The Authors 2017.

    The Senior Committee on Environmental, Safety, and Economic Aspects of Magnetic Fusion Energy (ESECOM) has assessed magnetic fusion energy's prospects for providing energy with economic, environmental, and safety characteristics that would be attractive compared with other energy sources (mainly fission) available in the year 2015 and beyond. ESECOM gives particular attention to the interaction of environmental, safety, and economic characteristics of a variety of magnetic fusion reactors, and compares them with a variety of fission cases. Eight fusion cases, two fusion-fission hybrid cases, and four fission cases are examined, using consistent economic and safety models. These models permit exploration of the environmental, safety, and economic potential of fusion concepts using a wide range of possible materials choices, power densities, power conversion schemes, and fuel cycles. The ESECOM analysis indicates that magnetic fusion energy systems have the potential to achieve costs-of-electricity comparable to those of present and future fission systems, coupled with significant safety and environmental advantages. 75 refs., 2 figs., 24 tabs

    Full Text Available Vegetable production, including that of chillies, plays an important role in agricultural sector and rural economic development worldwide. This is because of greater farm productivity with regard to vegetables than cereal and staple crops. This paper analyses the impact of seed technology development on the economic aspects of chilli production in Central Java. Particular attention is paid to improved varieties of chilli. Potential consequences of seed technology development are discussed. Data of this study are compiled from surveys conducted in three selected chilli producing regions in 2010-2012. The results show that the major varieties of chilli grown by surveyed farmers are grouped into three broad types: hybrids, local and improved open pollinated varieties. The chilli varieties farmers selected varied according to location and cropping season. In the dry season, farmers grew similar proportions of hybrid, local, and open pollinated types. Nevertheless, there were differences among the survey sites. Farmers grew different varieties to exploit seasonal microclimates and market preferences. Mostly, farmers selected varieties for economic motives. The consequence of growing hybrids was less use of agrochemicals, particularly pesticides, than for other varieties. Overall, they show the best economic performance in the study site. Development of seed technology should consider agro-ecological and economic aspects to obtain better outcomes. Private sector and national research institutions need to collaborate more to utilise available genetic resources to produce better varieties of chilli.

    Giuliano, V.; Lazzeri, L.

    1977-01-01

    The aim of this paper is a review of the main aspects of the design of a support structure of a LMFBR tank, with particular reference to the analysis of the non-linear dynamic behaviour of the structure in the plastic range under the effect of an explosive accident within the tank. The structure is composed by a L-shaped flange, which supports the tank, connected by means of nine square beams to a rigid box-type ring, fixed to the concrete. The plug of the tank is connected to the L-shaped figure by means of a group of SS bars. The non-linear dynamic analysis of the explosive accident has been carried out on a lumped mass model, with elastic-plastic elements which simulate main components of the support structure and tank. The impulsive load connected to the explosive accident has been modelled (on the basis of extensive comparative studies carried out) as two triangular pressure impulses acting on the plug and on the botton of the tank. A large amount of results, which describe displacements, velocities and accelerations of the plug, of the tank, and of the support structure, together with the forces and stresses acting on the main structural components are presented and discussed, with particular reference to the influence of the various parameters involved in the analysis.

    Expansion of the internal market and external, production on a large scale and more dynamic economic growth would be the consequences of a regional integration in South America. However, due to the specific characteristics of South America this process did not occur. Many attempts were made through the years with the creation of institutions that tried to promote the integration of different forms of South America. This article analyses the current economic conditions in which this initiative is to achieve an energy integration, which seems feasible given the provision expresses the presidents of South American countries before a possible rationing of energy. Through analysis of the results it may be concluded that there is a growing demand for energy in all countries, which should be resolved first in order not to cut the development of South America. The main economic aspects which affect the process of integrating energy are the commercial structures of energy, the energy complementarities, the degree of development of infrastructure for interconnection, the industrial structure and conformation electric business. However, an immediate solution would be to boost bilateral integration energy projects and construction of transmission lines that interconnect the regional stations for the supply of electric energy. Moreover, as the conditions are not improved political and economic and there is no compatible models between technical institutions and legal and administrative, will not be achieved significant progress in the process of regional energy integration of South America.

    The Belgian concept for shallow land disposal of low-level short-lived waste is approaching maturity. The paper presents its main design features, the construction and operating phases, and the economics of the project. The conclusion is that this concept is economically interesting when compared to the geological option. The financial approach adopted by Belgium is presented. Pros and cons of timely operation are discussed. Although it may look economically attractive to adopt a slow pace in implementing the concept, the paper shows that deferring decisions would be a risky attitude, in contradiction with fairness to future consumers. Such a conclusion derives from economic and financial arguments, considering that cost uncertainties, especially in the front-end, and financial management risk might be of overwhelming importance

    Full Text Available Poland in viewed by Ukraine as a reliable economic and political partner supporting Ukraine’s intention to integrate in Europe. Therefore, facts, documents and statistical data reflecting qualitative and quantitative aspects of relations between Ukraine and Poland need to be subject to non-stop monitoring and analysis, to help in finding timely solutions for problematic issues that may occur in these countries’ relations. The article’s objective is to analyze the performance and perspectives of economic and diplomatic relations between Ukraine and Republic of Poland. The analysis of documents on diplomatic and economic cooperation of the two countries after they gained political independence, and statistical data on trade in goods and services (by category and investment flows (by data on direct investment from Ukraine to Poland and from Poland to Ukraine shows that both countries have immense potentials for cooperation in various fields. As regards diplomatic dimension, Republic of Poland is the strongest promoter and lobbyist of the Euro-integration and Euro-Atlantic course of Ukraine. Regarding the economic cooperation, while mutual trade in goods declined in 2014 due to the economic and political crisis in Ukraine, it grew in 2016 with the recovery processes in the Ukrainian economy. Mutual trade in services is less intensive than trade in goods. Analysis of the investment cooperation shows the large asymmetry in favor of Polish investors in Ukraine and the reducing investment in both directions in the latest years.

  10. An Economic Aspect of the AVOID Programme: Analysis Using the AIM/CGE Model

    2010-05-01

    This presentation purposes to show the results of the analysis that the AIM/CGE [Global] model contributed to Work Stream 1 of the AVOID programme. Three economic models participate in this WS to analyze the economic aspects of defined climate policies, and the AIM/CGE [Global] model is one of them. The reference scenario is SRES A1B and five policy scenarios (2016.R2.H, 2016.R4.L, 2016.R5.L, 2030.R2.H, and 2030.R5.L) are considered. The climate policies are expressed as emissions pathways of several gases such as greenhouse gases and aerosols. The AIM/CGE [Global] model is a recursive dynamic global CGE model with 21 industrial sectors and 24 world regions. These definitions are based on the GTAP6 database and it is used as the economic data of the base year. Some important characteristics of this model can be summarized as follows: power generation by various sources (from non-renewables to renewables) are considered; CCS technology is modeled; biomass energy (both traditional and purpose-grown) production and consumption are included; not only CO2 emissions but also other gases are considered; international markets are modeled for international trade of some fossil fuels; relationships between the costs and resource reserves of fossil fuels are modeled. The model is run with 10-year time steps until 2100. For the reference case, there are no constraints and the model is run based on the drivers (assumptions on GDP and population for A1B) and AEEI. The reference case does not have the same emissions pathways as the prescribed emissions for A1B in AVOID. For scenario cases, the model is run under emissions constraints. In particular, for each policy scenario, the constraint on each gas in each 10-year step is derived. The percentage reduction in emissions that occurs between the AVOID A1B scenario and the particular policy scenario, for each gas in each 10-year period is first calculated, and then these percentage reductions are applied to the AIM reference case

    The aim of this paper is a review of the main aspects of the design of a support structure of a LMFBR tank, with particular reference to the analysis of the non-linear dynamic behavior of the structure in the plastic range under the effect of an explosive accident within the tank. The structure is composed by a L-shaped flange, which supports the tank, connected by means of nine square beams to a rigid box-type ring, fixed to the concrete. The plug of the tank is connected to the L-shaped flange by means of a group of SS bars. The non-linear dynamic analysis of the explosive accident has been carried out on a lumped mass model, with elastic-plastic elements which simulate main components of the support structure and tank. The impulsive load connected to the explosive accident has been modelled (on the basis of extensive comparative studies carried out) as two triangular pressure impulses has been the object of a parametric evaluation. The dynamic transient on the support structure during and after the explosive accident for each couple of pressure impulses has been analyzed by means of modified version of the NON SAP code running on a CDC 7600 computer. A large amount of results, which describe displacements, velocities and accelerations of the plug, of the tank, and of the support structure, together with the forces and stresses acting on the main structural components are presented and discussed, with particular reference to the influence of the various parameters involved in the analysis

    Site selection criteria for low and intermediate level waste repositories are usually well established as far as the technological and scientific bases are concerned. However, social, cultural and economical aspects need to be examined on a case by case basis because there are many situations to be faced before succeeding to convince the public and authorities that a waste repository is to be built at any chosen site. In the specific case of Goiania there is an ongoing process that started several years ago, to make the repository accepted by local, state and national authorities, and to answer legitimate questions raised by significant segments of the population. This paper will summarise those more relevant aspects concerning the site selection process for the Goiania repository. (author)

    Australia is the world's largest coal exporter, and coal is the nation's largest export and dominant revenue earner. The future competitiveness of coal will be maintained through improved preparation of coal for traditional markets, by upgrading for new markets, and via coal utilization processes that are more efficient and environmentally acceptable. Australia is also a niche supplier of technologies and services with the potential to expand. This potential extends to the increasing vertical integration of coal supplies (whether Australian, indigenous or blended) with downstream utilization such as power generation. Technological advancement is a key element of industry strategy and coal preparation research and development, and clean coal technologies are critical aspects. This paper summarizes these issues, linking the economic and environmental aspects across the coal production and utilization chain. (author). 2 tabs., 1 fig., 6 refs

    Short-term medical missions (STMMs) represent a grass-roots form of aid, transferring medical services rather than funds or equipment. The objective of this paper is to review empirical studies on social, economic and diplomatic aspects of STMMs. A systematic literature review was conducted by searching PubMed and EBSCOhost for articles published from 1947-2014 about medical missions to lower and middle income countries (LMICs). Publications focused on military, disaster and dental service trips were excluded. A data extraction process was used to identify publications relevant to our objective stated above. PubMed and EBSCOhost searches provided 4138 and 3262 articles respectively for review. Most articles that provide useful information have appeared in the current millennium and are found in focused surgical journals. Little attention is paid to aspects of volunteerism, altruism and philanthropy related to STMM activity in the literature reviewed (1 article). Evidence of professionalization remains scarce, although elements including guidelines and tactical instructions have been emerging (27 articles). Information on costs (10 articles) and commentary on the relevance of market forces (1 article) are limited. Analyses of spill-over effects, i.e., changing attitudes of physicians or their communities towards aid, and characterizations of STMMs as meaningful foreign aid or strategic diplomacy are few (4 articles). The literature on key social, economic and diplomatic aspects of STMMs and their consequences is sparse. Guidelines, tactical instructions and attempts at outcome measures are emerging that may better professionalize the otherwise unregulated activity. A broader discussion of these key aspects may lead to improved accountability and intercultural professionalism to accompany medical professionalism in STMM activity.

    Indicators of social and economic status are important health determinants. However, evidence for the influence of family socioeconomic status in adolescent wellbeing is inconsistent and during this period of development youth may begin to develop their own status positions. This study examined social and economic health inequalities by applying a multidimensional and youth-orientated approach. Using a recent (2010-2011) and representative sample of Swedish 14-year olds (n = 4456, 51 % females), the impact of family socioeconomic status, youth economic resources and peer status on internalizing symptoms and self-rated health were examined. Data was based on population register, sociometric and self-report information. Aspects of family socioeconomic status, youth's own economy and peer status each showed independent associations, with poorer wellbeing observed with lower status. However, there were equally strong or even stronger effects of peer status and youth's own economy than family socioeconomic status. Lower household income and occupational status were more predictive of poor self-rated health than of internalizing symptoms. The findings suggest that youth's own economy and peer status are as important as family socioeconomic status for understanding inequalities in wellbeing. Thus, a focus on youth-orientated conceptualizations of social and economic disadvantage during adolescence is warranted.

    Highlights: • Global environmental protection of using alternative fuel. • Economic aspects of palm oil biodiesel in Malaysia. • Tribological characteristics of palm oil biodiesel in engine components. • Engine performance and emission of palm oil biodiesel. • Effect of temperature on density and kinematic viscosity for various biodiesel. - Abstract: The high cost of energy supplies and the growing concern over the dependency on fossil fuels have impelled many countries to search for renewable and alternative energy sources. The extensive use of fossil fuels for transportation and power generation all over the world have caused the supply of fossil fuels to continuously decrease and have aggravated environmental pollution. Searching for alternative fuels has become imperative to reduce pollution and address the problems on fossil fuels. Vegetable oil fuels, such as palm oil biodiesel, serve as alternative forms of energy and are currently being studied, particularly as a diesel fuel substitute. The purpose of this study is to review the potential of palm oil as an energy source and alternative diesel fuel in terms of its performance, environmental impact, wear characteristics, and economic considerations. Compared with other vegetable oils, palm oil is a relatively sustainable, environment-friendly, less expensive, and economically beneficial potential source of energy. Palm oil plantation and production is a major industry in Malaysia, contributing to the economic growth and development of the country. The properties of palm oil biodiesel, namely, high oxidation stability, good cold properties, cetane number, and higher viscosity, makes it a suitable diesel substitute. Compared with other vegetable oils and petroleum diesel fuels, palm oil is associated with better engine performance, higher specific fuel consumption, and shorter ignition delay. Use of palm oil also reduces exhaust emission of hydrocarbon, carbon monoxide, carbon dioxide, and smoke, but

    Full Text Available It was aimed to investigate economic aspects of the establishment of traceability in the Mid-South region of MT, Brazil, methods of animal identification, complains, drawbacks and degree of importance given by ranchers. During May to July 2009 were conducted interviews with 13 owners of Rural Establishments Approved in SISBOV (ERAS and the survey of economic values practiced by three certifying companies and one slaughterhouse from the region. All the farms interviewed utilized earring and bottom. The main difficulties for the establishment of tracking were the frequent changes (46.30%, the understanding of the laws (30.57%, and the choice of the certifier (23.13%. The greatest drawbacks of Cattle and Buffalo Identification and Certification System (SISBOV were the excessive delay of official audits (53.85%, the instability of differential value (23.10%, loss of identification elements (15.39% and the delay when requested earring reprinting (7.69%. The importance ascribed was ensuring the credibility and adding value to the Brazilian product (84.61%. The individual value for the tracking process was R$ 4,34. The difference of tracked animal slaughtered for the European Union was R$ 10,73@-1. The establishment of the tracking system presented economic viability and the variation of the values paid by the tracked meat despite animals aiming exportation.

  6. Energy rebound and economic growth: A review of the main issues and research needs

    International Nuclear Information System (INIS)

    Madlener, R.; Alcott, B.

    Contrary to conventional wisdom, more efficient use of energy may actually through rebound effects lead to greater instead of less total consumption of energy-or at least to no diminution of energy consumption. If so, energy efficiency strategies may serve goals of raising economic growth and affluence, but as an environmental or energy policy strategy could backfire, leading to more resource use in absolute terms rather than less. This, in turn, could in the long run hamper economic growth, for instance if resource scarcity crowds out technical change. The hypothesis that rebound is greater than unity ('backfire') predicts the observed real-world correlation between rising energy consumption and rising efficiency of energy services, however difficult it may be to define a precise holistic metric for the latter. The opposing hypothesis, i.e. that rebound is less than unity and that energy efficiency increases therefore result in less energy consumption than before, requires on the other hand strong forces that do account for the empirically observed economic growth. This paper summarises some of the discussions around the rebound effect, puts it into perspective to economic growth, and provides some insights at the end that can guide future empirical research on the rebound topic

It is stated that with the age of young consumers their purchasing fund and sources of its recruiting were increasing. Teenagers (secondary-school people more often demonstrate also a tendency to save money to concrete objectives, e.g. holidays, travels, training, but their current expenses are concentrating mainly around different active or passive forms of spending free time. Older teenagers are also more critical in relation to advertisements, and price and different instruments of sales promotion are factors which are exerting a significant influence on their purchase decisions. With the growth of importance of goods in the hierarchy of satisfying needs, role of determinants of choice besides the price, also a brand of the product are assumed.

    The consumption of bottled water in Italy began in the 1970s. Since then, this usage has grown considerably, also as a result of changes in habits. The environmental impact as a result of the water production chain is very significant; it would be considered, for example, the use of plastic bottles, the consumption of oil in the production of the bottles, the emission of air from the vehicles that transport the bottles, non-recycled plastic packaging, etc. In this study, considering the comparison between two situations, use of bottled water and use of water kiosk (WK), an environmental and economic impact evaluation has been done. The study considered the production of a WK in a town with 9000 inhabitants, which supplies controlled, still and sparkling water, with an organoleptic quality higher than tap water coming from the aqueduct. In particular, taking into consideration the environmental aspects, specific attention was paid both to CO2 emissions and PET bottle waste reduction. The economic impact evaluation was carried out from the consumer's point of view. In order to provide a supply service that was economically sustainable, a calculation was done with the aim of determining a specific fee for the supplied water. Moreover, a comparison has been made between quality parameters achieved with the analysis of water from aqueducts with the limits established in the Italian legislation and the parameters of several Italian water brands. The study has the aim at considering the opportunity to follow a different people's habits, closer to the concept of sustainability, reducing the environmental charge related to the realization, transport and consumption of plastic water bottles without significant reduction of the quality of the service and with convenient and interesting economic implications. In fact the results of the study show that the alternative of WKs is more efficient in economic and environmental terms respect to the use of bottled water. Copyright

The economic impact evaluation was carried out from the consumer’s point of view. In order to provide a supply service that was economically sustainable, a calculation was done with the aim of determining a specific fee for the supplied water. Moreover, a comparison has been made between quality parameters achieved with the analysis of water from aqueducts with the limits established in the Italian legislation and the parameters of several Italian water brands. The study has the aim at considering the opportunity to follow a different people’s habits, closer to the concept of sustainability, reducing the environmental charge related to the realization, transport and consumption of plastic water bottles without significant reduction of the quality of the service and with convenient and interesting economic implications. In fact the results of the study show that the alternative of WKs is more efficient in economic and environmental terms respect to the use of bottled water.

    Full Text Available Purpose of this paper consists in analyzing economic and social aspects of demographic aging process in Moldova. To interpret the accumulated data and calculations performed analytical method of calculation tabular method and graphical method was applied. Intense process of aging is associated with changes in all spheres of social and economic life and affects equally the interests of older people and society as a whole. In Republic of Moldova aging population has grown in the last two decades, being conditioned both declining birth rate, which is very low and does not provide simple reproduction of the population and the mass migration of population that leads to the depopulation of the country. Maintaining the natural and migration increase with negative values amplifies the negative demographic deterioration of the country, which influences economic development, competitiveness and stability of the country and welfare of its citizens. In this situation it is necessary to respond positively to the challenges of demographic change through the complex and multisectoral approaches designed to correct current unfavorable demographic evolutions.

  15. Assessing the economic aspects of solar hot water production in Greece

    1997-01-01

    The long-term performance of various systems was determined and the economic aspects of solar hot water production were investigated in this work. The effect of the collector inclination angle, collector area and storage volume was examined for all systems, and various climatic conditions and their payback period was calculated. It was found that the collector inclination angle does not have a significant effect on system performance. Large collector areas have a diminishing effect on the system's overall efficiency. The increase in storage volume has a detrimental effect for small daily load volumes, but a beneficial one when there is a large daily consumption. Solar energy was found to be truly competitive when the conventional fuel being substituted is electricity, and it should not replace diesel oil on pure economic grounds. Large daily load volumes and large collector areas are in general associated with shorter payback periods. Overall, the systems are oversized and are economically suitable for large daily hot water load volumes. (Author)

    Full Text Available The economic crisis in Italy after 2008 fully revealed the complexity of the socio-economic model of the country, which in our time is formed not only at national level but also at European and global levels. All these factors should also be taken into account in the analysis of Russian-Italian relations. Italy has traditionally been considered one of the main partners / allies of Russia in Europe / the West, which emphasizes the active economic ties.Socio-economic diffi culties in Italy, creating both challenges and opportunities for the world, Europe and Russia. One of the major challenges for the global economy is the impact of the crisis in Italy for the EU, as one of the world's economic centers.The challenge for the EU crisis in Italy can be the stability of the EU, the challenge for Russia could be the eff ect of reducing the role of the traditional economic and political partner of the EU. Regarding the new features are: the global level – the transformation of one of the major economies of the West and building relationships with updated economic leader of the Mediterranean on a new basis, the regional level - the further development of one of the other German centre’s of the EU, which could serve as a new "stimulus" for the further integration of the Union , national - improve the socio-economic standards of living of citizens in Italy, as well as creating additional opportunities for the development of mutually benefi cial cooperation with other countries, particularly with Russia.

    Implications for Hospitals and Departments of Anaesthesiology. This article outlines the new German health care laws and their impact on the statutory health care system, hospitals and anaesthesia departments. The German health care system provides coverage for all citizens, although financial support from the public sector is on the downgrade. Hence, pressure to reduce public sector health care spending is likely to continue in the near future. Hospital costs account for one-third of total health care spending in Germany, and hospitals are facing increasing economic constraints: the volume and the charges for specific medical treatments are negotiated between the hospitals and the insurance agencies (or sickness funds) in advance. Only part of hospital care is still reimbursed on the basis of a per diem rate, and an increasing number of services are based on fixed payments per case or treatment. Reducing the costs for this treatment is therefore of utmost importance for hospitals and hospital departments. The prospective payment system and the pressure to contain costs demand a controlling system that allows for cost accounting per case. However, an economic evaluation must include comparative analysis of alternative therapeutic options in terms of both costs and outcome. Economic aspects challenge the traditional relationship between physicians and patients: doctors are still the advocates of their patients, but also act as agents for their institutions. Nevertheless, not only economic issues, but also ethical priorities and the value of an anaesthetic practice must be considered in the era of cost containment. Anaesthetists must be actively involved in providing high-quality care with its obvious benefits for the patient and be able to resist efforts to cut out expensive treatment modalities regardless of their benefits.

Non-specific questionnaires are adopted for dry eye. Additionally, 36‑item Medical Outcomes Study-Short Form (MOS-SF-36 and benefit evaluation method were developed. Methods. Information analysis and mathematical methods and public health technology evaluation methods (i.e., modelling, analysis of disease burden, and budget impact analysis were applied to economic aspect study. Decision tree model based on these finding was developed and applied to cost estimating of blepharoconjunctival and exogenous dry eye treatment in computer vision syndrome. Two scenarios of patient management were considered, i.e., typical management and management using therapeutic eyelid hygiene. Similar model was developed for early postoperative period after LASIK. Short-run analysis (1 year was performed, direct medical costs were considered. This analysis implies the calculation of overall cost (economic burden of the disease. Official data on adult population size in 2014 and the occurrence of the disease were used to assess prevalence. Budget impact analysis evaluates the difference in total economic effects due to comparison technology use in money terms. Sensitivity analysis assesses the stability of simulation results. Medical treatment cost was considered the most valuable parameter. Results and conclusions. Direct medical costs of typical management and management using therapeutic eyelid hygiene in demodicosis, computer vision syndrome, and after LASIK were 14,623 RUB and 9,200 RUB (savings of 37 %, 17,630 RUB and 9,200 RUB (savings of 47 %, 4,425.5 RUB and 3,004 RUB (savings of 32 %, respectively. Analysis of economic burden with respect to disease occurrence and typical management costs demonstrated that in 2015 this parameter was estimated as 576,198,416,556 RUB.

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

    International Nuclear Information System (INIS)

    2005-11-01

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

  1. Economic and technological aspects of the market introduction of renewable power technologies

    Science.gov (United States)

    Worlen, Christine M.

    Renewable energy, if developed and delivered with appropriate technologies, is cleaner, more evenly distributed, and safer than conventional energy systems. Many countries and several states in the United States promote the development and introduction of technologies for "green" electricity production. This dissertation investigates economic and technological aspects of this process for wind energy. In liberalized electricity markets, policy makers use economic incentives to encourage the adoption of renewables. Choosing from a large range of possible policies and instruments is a multi-criteria decision process. This dissertation evaluates the criteria used and the trade-offs among the criteria, and develops a hierarchical flow scheme that policy makers can use to choose the most appropriate policy for a given situation. Economic incentives and market transformation programs seek to reduce costs through mass deployment in order to make renewable technologies competitive. Cost reduction is measured in "experience curves" that posit negative exponential relationships between cumulative deployment and production cost. This analysis reveals the weaknesses in conventional experience curve analyses for wind turbines, and concludes that the concept is limited by data availability, a weak conceptual foundation, and inappropriate statistical estimation. A revised model specifies a more complete set of economic and technological forces that determine the cost of wind power. Econometric results indicate that experience and upscaling of turbine sizes accounted for the observed cost reduction in wind turbines in the United States, Denmark and Germany between 1983 and 2001. These trends are likely to continue. In addition, future cost reductions will result from economies of scale in production. Observed differences in the performance of theoretically equivalent policy instruments could arise from economic uncertainty. To test this hypothesis, a methodology for the

    Results are presented of the AERTOs project (Associated European Research and Technology Organisations). The objective is to identify, design and implement joint, long-term, sustainable cooperation activities between RTOs (Research and Technology Organisations). The purpose of this work is a bottom-up approach to develop and deploy joint activities towards a Bio-based Economy. The results of this report will deliver input for a more extensive paper about the position of the RTOs in Europe. This report contains a quick scan of various biomass value chains that could emerge. Together with the AERTOs partners several bio-based chains were selected for further evaluation. Next, the technological, economical and environmental aspects of each step of the production chain were determined. By integrating this data over the full chain, the chains could be compared to each other in a consistent way. A sensitivity analysis then provided insight into the bottlenecks in the value chain.

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

    The trousseau is notorious since antiquity and has been influenced by a series of modifications, reflected in the type of fabric, confection, design, fashion and market share. This study aimed to present economic and design aspects of the bedding, table and bath linen sector (also known as bed, bath and beyond) occurred from the second half of the 20th century to recently in Brazil. A bibliographic research was carried out from the scientific literature and magazines of the area, notably the “Revista Vogue Casa Brasil” (“Vogue House Brazil Magazine”). It is concluded that the classic patterns predominate: white color and cotton in bed, table and bath products, being embroidery the most outstanding style ornament. The maintenance of these standards by the Brazilian manufacturers is interesting to maintain sales in the domestic market, but a limitation for export products destined to publics with different values and aesthetic tastes and with greater supply of items with variety of surface designs.

    Dominant plasma self-induced current equilibrium is achieved together with the high β for the steady-state neoclassical reversed field pinch (RFP) equilibrium with low aspect ratio by broadening the plasma pressure profile. The RF-driven current, when the safety factor is smaller than unity, is much less than the self-induced current, which dominates (96%) the toroidal current. This neoclassical RFP equilibrium has strong magnetic shear or a high-stability beta (β t = 63%) due to its hollow current profile. It is shown that the obtained equilibrium is close to the relaxed-equilibrium state with a minimum energy, and is also robust against microinstabilities. These attractive features allow the economical design of compact steady-state fusion power plants with low cost of electricity (COE). (author)

    Cloud computing opens new perspectives for small-medium biotechnology laboratories that need to perform bioinformatics analysis in a flexible and effective way. This seems particularly true for hybrid clouds that couple the scalability offered by general-purpose public clouds with the greater control and ad hoc customizations supplied by the private ones. A hybrid cloud broker, acting as an intermediary between users and public providers, can support customers in the selection of the most suitable offers, optionally adding the provisioning of dedicated services with higher levels of quality. This paper analyses some economic and practical aspects of exploiting cloud computing in a real research scenario for the in silico drug discovery in terms of requirements, costs, and computational load based on the number of expected users. In particular, our work is aimed at supporting both the researchers and the cloud broker delivering an IaaS cloud infrastructure for biotechnology laboratories exposing different levels of nonfunctional requirements.

    Full Text Available The production of vegetable charcoal generates atmospheric emissions, which can be controlled by the instalation of collectors for the condensation of such emissions, forming the pyroligneous acid. The development of collectors for the condensations and characterization of the acid for commerce can contribute with the local sustainable development. This study intends to investigate the technological, economical and legal aspects of the production and commerce of the pyroligneous acid. The chosen method was case study in Presidente Lucena/RS, Brazil, with use of surveys, interviews with producers and responsible government sectors’ representatives. The results indicate that the pyroligneous acid extraction technique is little-known and little used by the producers, that the current market does not absorb the pyroligneous acid offering and the ruling is not relevant.

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

    Mass spectrometry proved to be very useful for solving analytical problems in food and agricultural industries. Its essential properties are: high resolution mass spectrometry allows to find the molecular structure of an isolated compound, even with a very small sample; associated with on line gas chromatographic separation, it gives the possibility to identify a great number of components in a small complex extract; isotope determinations by mass spectrometry give an essential contribution to follow kinetic mechanisms of formation of natural molecules in plant-growing, photosynthesis, fertilization, ..., leading to identification of the origin of foods and beverages. The economical aspect of mass spectrometry is characterized by the cost of investment in instrumentation and the necessary high level of competence of the technicians [fr

    The selection of the working fluid for Organic Rankine Cycles has traditionally been addressed from systematic heuristic methods, which perform a characterization and prior selection considering mainly one objective, thus avoiding a selection considering simultaneously the objectives related to sustainability and safety. The objective of this work is to propose a methodology for the optimal selection of the working fluid for Organic Rankine Cycles. The model is presented as a multi-objective approach, which simultaneously considers the economic, environmental and safety aspects. The economic objective function considers the profit obtained by selling the energy produced. Safety was evaluated in terms of individual risk for each of the components of the Organic Rankine Cycles and it was formulated as a function of the operating conditions and hazardous properties of each working fluid. The environmental function is based on carbon dioxide emissions, considering carbon dioxide mitigation, emission due to the use of cooling water as well emissions due material release. The methodology was applied to the case of geothermal facilities to select the optimal working fluid although it can be extended to waste heat recovery. The results show that the hydrocarbons represent better solutions, thus among a list of 24 working fluids, toluene is selected as the best fluid. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Andrei BIRMAN

    2011-12-01

    Full Text Available This study briefly presents theoretical aspects related to the relationship between inflation and economic growth and provides an empirical study for the Romanian economy, for the period 2000 – 2011. The econometric methodology used is that of vector auto-regressions.The results showed that a sudden increase in the change of the output gap (i.e. a shock to the growth rate of the output gap does not determine an increase in CPI. Hence, the hypothesis of the existence of a speed limit effect in Romania is rejected. In concrete terms, this means that the monetary authorities should not fear for eventual inflationary pressures when sudden increases of demand arise, if the output gap is negative (the potential output is higher that the effective output. The National Bank of Romania may avoid, therefore, taking some monetary policy decisions meant to temper the rise in inflation (as would have been the case if a speed limit effect was present but which would have induced unnecessary volatility into the output. However, the study indicates that National Bank of Romania should communicate to the public the state of the economy in order to timely anchor the inflation expectations. This is a very important aspect, since the inflation expectations firmly react to a shock into the growth rate of the output gap, i.e. to a strong increase in the effective output.The study also showed a positive response of the growth rate of the output gap to a positive shock in inflation, with a maximum effect after three quarters. This shows that the inflation was mainly driven by demand factors in the analysed period, with the consumers increasing current consumption in order to avoid the future higher prices and with the economic agents increasing the supply such as to maximise the unitary profits. Also, this result shows a rather inelastic demand or a possible captivity of consumers in the face of producers.

  14. Analysis of legal and economic aspects of precipitation weather derivatives for Serbian agricultural sector

    2014-01-01

    Full Text Available Weather derivatives are not present in Serbia nor in the neighbouring countries and have no significant application in the European Union, either. Weather derivatives originated in the USA, where the market for these instruments is most developed, in terms of both economy and law. However, positive effects of their application, through the decrease of influence of unfavourable weather conditions on agricultural crops, are a good basis for their further study. The most common reasons for their absence from our financial market are their complexity and the inexistence of prerequisites for their introduction. This paper analyses legal and economic aspects of weather derivatives, as forms of financial derivatives, as well as weather derivative contracts concluded with the aim of hedging against precipitation exposure. The goal of the analysis is to find an optimal contract structure, but also the conditions that have to be met in order for its signing to be economically justified for both contractual parties, as well as the creation of preconditions for this weather derivative contract to be the instrument of trade on the financial market. The paper also analyses normative frameworks for the conclusion of these derivative contracts, as well as the necessity to educate market participants, which refers both to agricultural producers and financial institutions. Furthermore, it emphasizes the difference in relation to the classical contract of insurance against drought risk.

    Yoshizaki, Haruki; Nakata, Toshihiko

    The advantages of coal are the largest reserves among any other fossil fuels, and can be found in many places including some developed countries. Due to the weak energy security of Japan, it is necessary to use coal as an energy source. We have designed the detailed energy model of electricity sector in which we take both energy conversion efficiency and economic aspects into consideration. The Japan model means an energy-economic model focusing on the structure of the energy supply and demand in Japan. Furthermore, the most suitable carbon capture and storage (CCS) system consisting of CO2 collection, transportation, storages are assumed. This paper examines the introduction of clean coal technologies (CCT's) with CCS into the electricity market in Japan, and explores policy options for the promotion of CCT's combined with CCS. We have analyzed the impacts of carbon tax where each fossil technology, combined with CCS, becomes competitive in possible market. CO2 mitigation costs for all plants with CCS are detailed and compared.

    Full Text Available The examination of disadvantaged regions goes back to a long history, greatly influenced by the ever-changing natural, economic and human resources. Consequently, while examining the disadvantaged areas, we face new systems of coherences. Today’s regional policy also needs to answer the question whether the spatial development funds of the past have been efficient or not and whether the land use distribution influences the spatial competitiveness or not. As we move towards 2015, we must consider the actual state of delivery of the Millennium Development Goals (MDGs in the Least Developed Countries (LDCs and address the above-mentioned issues in order to realise the international political commitment to leave no one behind. In this paper, we have shown some aspects of spatial economic processes through the example of the Hungarian disadvantaged areas. These issues are timely because the usefulness of the research is important, ranging from rural development to spatial planning and the elaboration of local and regional development strategies. Spatial discrepancies in Hungary cause the disadvantage of rural areas, contributing to their lagging behind compared to the urban areas (Kollár, 2012.

    As a country with hundreds million people, Indonesia needs to generate large scale power and distribute it to thorough country to improve gross domestic product of the population. In the power transmission domain, the High Voltage Direct Current (HVDC) transmission system should be considered for the next decades concerning any technical and economical problems with HVAC transmission. HVDC transmission system is the answer for the Indonesian condition. This system can connect the high energy potential regions to the high energy demand regions. HVDC is the most efficient to transport energy from one region to another one region. Dismantling and removing assets costs are included to the estimated for capital costs, while the environmental and property costs are the costs of securing designations and resource consents, and valuation and legal advice for the HVDC investment. Although converter terminals are expensive however, for long transmissions HVDC system can compensate the costs over breakeven distance through very efficient transmission system. Efficiency of HVDC is appearing from conductor wire, supporting tower, low energy loses and free space used by route of the transmission line. HVDC system is also free from some problem, concerning stability, inductive and capacitive load components, phase differences and frequency system. In the economic aspect the HVDC capital costs for the transmission options comprise estimates of the cost to design, purchase and construct new HVDC transmission components. While operating and maintenance costs of HVDC assets comprise the costs for replacement the old existing overhead transmission lines, underground and submarine cables, and HVDC converter station components.

    Full Text Available

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

Increasing reliability of these sources automatically influence the quality and availability of this type of power supply. Every solar and wind energy system includes a certain number of principle components : Photovoltaic arrays or wind generator, regulator/control unit to control charge/ discharge of the batteries and power supply to consumers, converters from AC to DC and DC to AC, batteries and load. The mode of system operation for both the independent or combined system is influenced by many complicated factors some of which are stochastic variables, time and location variables or constant. From the above complicated data one must choose the optimal system which answers the following criteria: a. Minimum cost which determines the inter relative array sizes for combined systems (photovoltaic cells wind generator and batteries). b. Reliability of power supply in general. c. Full consumption of power installation by obtaining maximum possible output under existing conditions at any time. This paper deals with the connected problems caused in a combined system of solar/photovoltaic cells, wind generator and batteries and will offer alternative economic and technical alternatives for power supply from fuel operated generators . Inverter components: photovoltaic cells and wind generators, which are the principle components without which solar and/or wind systems cannot exist, are discussed from the theoretical and physical aspects. Also, operation of the attached components, such as batteries, inverters, generators, regulators etc, is discussed. The last part of this paper discusses the choosing of the optimal system in a Techno-economic sense as opposed to energy supplied from generator, The work exhibited on these pages will contribute to better understanding of the different systems while

    Full Text Available The electricity sector represents the sector with the greatest impact in terms of producing climate change, mainly due to the greenhouse gas emissions generated through the burning of fossil fuels. It is not however the only negative aspect associated to the classic technologies of electricity production. This paper aims to assess the economic and environmental aspects associated to the technologies for the electricity production from conventional sources and as a conclusion of the research it will also propose certain specific measures designed to mitigate their impacts. Therefore, the analysis will focus on economic issues, such as limited resources of fuels and the significant fluctuation in fuel prices, low energy efficiency, environmental protection expenditures and health issues as a result of the pollution generated by the electricity production and environmental aspects related primarily to the burning of fossil fuels, but also to extraction, transport and storage, aspects concerning the management of waste generated by the energy sector or to the risks associated with the process of producing electricity. In the final part of the paper a few measures will be proposed to mitigate the impact on the environment and economic development of such technologies, as well as increasing energy efficiency, promoting renewable sources of energy, carbon dioxide capture and storage, limiting deforestation, afforestation or the prevention of accidents in the energy sector.

    Load problems in electricity markets occur both on the supply and demand side and can have technical, economic and even political causes. Commonly, such problems have been solved by expanding production and/or distribution capacity, importing electricity or by load management. Load management is a techno-economic measure for harmonizing the relations between supply and demand sides, optimizing power generation and transmission and increasing security of supply. Interest in load management differs depending on the perspective of the actors involved: from customer, utility, or producer to state policy maker. The problem of load demand and load management in residential sector is in this thesis approached from different perspectives, i.e. technical, economic, and environmental. The study does not go deep into detailed analyses of each perspective, but rather aims to establish and analyze the links between them. This trans-disciplinary approach is the key methodological moment used in the research work performed by the research group for load management in buildings at the Lund Institute of Technology. The key objective of this study is to analyze load demand variation and load management possibilities in residential sector, particularly detached and semi-detached houses, to experimentally test and analyze the conditions and potential of direct load management from customer and utility viewpoint. Techno-economic and environmental aspects are investigated. The study was performed in collaboration with one electric utility in Southern Sweden. Ten electric-heated houses were equipped with extra meters, enabling hourly load measurements for heating, hot water and total electricity use. Household heating and hot water systems were controlled by the utility using an existing remote reading and monitoring system. The residents noticed some of the control periods, although they didn't express any larger discomfort. The experiments proved that direct load management might

    For determining the feasibility study on manufacturing nuclear fuel element from economical aspect point of view, it necessary to fix its capacity which it was found from fuel element reloading requirement for nuclear power plat (PLTN). NEWJEC report which use as a base in this study that is possibly of a complex of NPP as big as 7200 MW in Muria region. If the capacity factor is 80 %, the reload requirement is therefore become from 120 to 142 tons uranium every year. So, its considered to fix the nominal capacity of a fabric for nuclear fuel element manufacturing as much as 200 tons-U per year with economical lifetimes of 20 years. NEWJEC data show, for manufacturing capacity of 200 tons-U per year with, plant have a fixed capital investment of US$ 43.9 million. With working capital as much as 15 % correspond to fixed capital investment (FCI); 10 % of interest rate; US$ 17 million of fixed cost; US$ 106.2/kg-U of variable production cost, its calculated that break even point/BEP is 50 % for price of nuclear fuel is US$ 350/kg-U without uranium cost. On this economic condition, it was found that the return on investment/ROI is 20.2 %; the internal rate of return/IRR is 11.2 % and the benefit cost ration/BCR is 1.22. For all of above, it was assumed that such nuclear fuel element manufacturing service will be operate in the year of 2012. Some of NEWJEC data have been revised, there were the value of FCI; cost of salary; the value in percent of working capital/WC; the cost of non-uranium materials and the price of product service are US$ 68 million; US$ 4.1 million; 30 %; US$ 100/kg-U and US$ 370/kg-U respectively, where the new data appear as higher than old date from NEWJEC, excluding the cost of salary. For all new economical data in the latest, we found that 45 %; 16.73 %; 11.8 % and 1.25 for BEB; IRR and BCR respectively

    This paper compares the Lead-cooled Fast Reactor (LFR) and the Sodium-cooled Fast Reactor (SFR) regarding different aspects of the coolant, safety and economics. A brief review of design and safety experience of an SFR (BN-600) and some safety philosophy of the most developed LFR (BREST) are presented as well. The pros and cons of the lead and the sodium coolants are discussed. This paper presents results concerning the coolant temperature evolution during three accident scenarios, i.e. Loss-Of- Flow (LOF), Loss-Of-Heat-Sink (LOHS), and Total-Loss-Of-Power (TLOP). It also studies possible moderators, like BeO and hydrides, for the core designs to have negative reactivity feedbacks and favorable reactivity swings. LFR seems to be able to accommodate more minor actinides than SFR at comparable coolant and Doppler feedbacks. We show that LFR can be designed both to breed and burn transuranics from LWRs. The hydrides lead to the most favorable reactivity feedbacks, but the poorest reactivity swing. It is shown that the LFR can handle the LOF transient better than the SFR. This is due to the much lower pressure drop in the LFR core. The coolant outlet temperatures stabilize at 2050 K and 940 K for SFR and LFR, respectively when no feedbacks are considered. Investigations also concern the SFR's performance when the pitch-to-diameter was increased from 1.2 to 1.4. For the LOHS and TLOP accidents their temperature evolutions are milder for the LFR since lead has a 50% larger volumetric heat capacity. For the TLOP the core outlet temperature of the LFR peaks at 1080 K after 2 days. Regarding economics it appears easier to avoid an intermediate cycle in an LFR than an SFR. (authors)

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

    The emission of environmental pollutants such as SO 2 and NO x into atmosphere from heavy industrial activity, and in particular from fossil fuel burning in electricity production, is arousing increasing concern. One of the three areas of the world most affected by the resultant acid rain lies in eastern and central Europe includes Poland, parts of Germany, the Czech Republic and Slovakia. A major contribution to this pollution comes from the burning of poor quality pit and brown coal with a high sulphur content. These effects, as well as polluted air reaching Poland from other countries, have begun to damage forests and cause public health concerns in regions of high industrial density. Many countries around the world have started to impose industrial emission limits and this move has generated renewed interest in finding viable and cost effective solutions to SO 2 and NO x pollution control. The conventional technologies - wet scrubbing for SO 2 and selective catalytic reduction for NO x now reached their full potential, these methods are not expected to provide further improvements in terms of efficiency or reduction in construction costs. A new technology being investigated for industrial scale commercial viability. One of them is the electron beam dry scrubbing process, which allows the simultaneous removal of SO 2 and NO x from industrial flue gases. The economical aspects of this technology are discussed in the presented paper

    Due to the great increase demand for energy in the world, the continuous expansion of industrialization and the increase of consumption, together with the indispensable search for the sustainability of human acts, the need for diversification of the energy matrix and the search for less polluting energy comes increasing. Nuclear energy is increasingly seen as an option to contain greenhouse gas emissions and reduce dependence on fossil fuels. In this context, although it is not a source of renewable energy and also not the solution to all Brazilian problems, it can contribute to the expansion of the Brazilian energy matrix, being the only thermal source capable of guaranteeing the constant supply of energy without emitting greenhouse gases, considering that Brazil dominates nuclear fuel cycle technology and has large uranium reserves. However, this is a topic that generates a great deal of insecurity and questioning, making important the development of this work, both for a better understanding of the public, and to contribute and encourage future research through an evaluation of its environmental and socioeconomic aspects, discussing its risks and assessing the possibilities of expanding its use, including a panoramic view of nuclear energy in Brazil. In addition, for the full development of a country, it is necessary to diversify its energy sources, focusing on environmental and economic sustainability and reducing the vulnerability of the system

    Full Text Available The authors performed an analysis of published stadies devoted to osteoporosis situation in Russian Federation including epidemiological, social, medical and economical aspects of this pathology. The analysis demonstrated that osteoporosis is reported in every third woman and every forth man of 50 years old and older. Seven vertebra fractures happen every minute and one fracture of proximal femur — every 5 minutes in Russia. An overall number of all key osteoporotic fractures will increase from 590 thousand up to 730 thousand cases by the year 2035. Osteoporosis is financially demanding for healthcare due to high treatment cost of fractures that are accompanied by life quality deterioration, high mortality and invalidization of patients. Epidemiological studies demonstrated that due to high fracture risk the osteoporosis therapy should be assigned to 31% of female and 4% of male patients over 50 years old. Such factors of osteoporosis risks are widespread in the society: smoking, low food calcium consumption, vitamin D deficit, low physical activity. The authors analyzed the problems in organization of medical care to patients with osteoporosis and osteoporotic fractures and possible solutions to existing issues. The organization of healthcare should be addressed at identification of high risk patient groups, early diagnosis and assignment of corresponding treatment aimed at decreasing potential fracture risk as well as at pathology prophylaxis.

    Full Text Available The subject of the study is the socio-economic aspects of the social responsibility of business (CSR in 4 countries. The purpose of the article is to study the experience in regulating the socio-economic responsibility of entrepreneurship in the United States, Sweden, India, and China to determine the direction of formation of the state mechanism of socio-economic responsibility of entrepreneurship (SERE in Ukraine. The methodology of the article became theoretical researches of foreign scientists, their synthesis, systematization, and analysis for the development of the application of experience in Ukrainian realities. The analysis showed how different states of CSR policy differ in each of these countries and made it possible to draw conclusions about the application in Ukraine. So, the experience of Sweden is useful in reviewing the social reporting obligation, as well as the experience of China. In the case of the USA, the role of the state in regulating CSRs in enterprises should be noted but, at the same time, the significant social consciousness of American entrepreneurs as recognized philanthropists, who are actively introducing ethical codes and key stewards from the implementation of CSR, are seen by society and aimed at improving the well-being of society. In China, the government plays an important role in the implementation of CSR for state-owned enterprises. In addition, laws are adopted to improve the rights of employees, to equalize gender differences, to increase the level of production, quality of products, which leads to an improvement in the quality of life of the country’s population. All this becomes relevant for Ukraine and can be used in our country as well. Indian experience draws attention through the adoption of a unique decision on the indifference of charity activities by Indian companies with a certain level of profit and the adoption of them by the rules of corporate social responsibility.

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

    Full Text Available The contract of insurance of crops and yields against drought is based on the risk of decrease of precipitation in comparison with an earlier relevant period. The authors analysed the specificities of the case of draught risk, but also other regulations characteristic of this contractual relationship, both from the economic and the legal point of view. The paper also treats the position of contractual parties in this contractual relationship, partly arising from the monopolising position of the insuring organisation. That part also analyses the contract freedom that is endangered due to unequal positions of contractual parties. Special attention is paid to legal sources, especially the general and special conditions of insurance organisations, seeing as they are the main source of law, as there is a lack of legal regulation of this field. The number of Serbian insurance organisations that offer this type of insurance is extremely low, as well as the percentage of insurance against this risk. The authors analyse the reasons for which this type of insurance is underdeveloped in Serbia, as well as the consequences of such a state to a safe agricultural production. The paper also covers the topic of the role of legislators and the state in general, in terms of regulation of certain elements of this contractual relation, but also in terms of state incentives that would contribute to a higher percentage of insured agricultural areas. This would reduce the uncertainty and the damage suffered by agricultural producers due to increasing weather fluctuations. Taking into account the inadequate legal and economic tradition, education in this field would represent a significant contribution to the development of this kind of insurance. The authors analyse the difference between the contracts of insurance of crops and yields against drought and the weather derivative contracts, which can be traded on the stock market.

    Biomass plays a key role to achieve the EU's 20-20-20 energy and climate targets. Because of rising European demand and limited domestic resources, the EU relies on worldwide imports. Given this framework, the present thesis explores the influences on wood pellet supply chains considering different environmental policies, price risks and the effect of torrefaction pretreatment. The examinations refer to three real case studies for pellet trade from Australia, Canada, and Russia to Europe. In the first investigation, the efficiency of co-firing imported wood pellets in terms of CO{sub 2} savings and related subsidy schemes is analysed. Scenarios show that co-firing biomass is efficient to contribute to the EU energy targets. Though, policy makers could use these instruments more effective when directing sourcing decision towards options with even less environmental impacts. The second analysis explores the influence of statistically derived price risks on total supply chain economics. It is shown that price risks can effect strong fluctuations in the short term, which seriously affect the profitability of individual trade routes. Securing the supply chain is mainly based on individual producer-buyer agreements, personal branch experiences and fast reactions on the subsidy system. Systematic evaluation of supply chains could contribute to a more reliable market and thus foster investment decisions. In the last investigation, the economic and environmental performance of potential torrefaction-based supply chains is assessed. As a result, torrefaction-based supply chains turn out to be a certain alternative to conventional ones. Though, still huge research efforts and industrial demonstration are required to make torrefied biomass a real alternative on the market.

    Full Text Available The existing system of housing and utility services functioning is carried out for providing the relevant living environment standards to the population by means of effective functioning of the system of uninterrupted providing housing and utility services according to existing requirements of the Russian standards. Today there is a number of problems, which doesn't allow housing and utility services to function effectively. The main of them is providing high-quality housing and utility services to the population and system of their objective cost assessment. This problem is solved by means of reforming the housing and utility sphere with the possibility of attracting financial resources from private investors. Housing and Utility of the Russian Federation, the basis of which is the housing stock, has a very high specific weight in fixed assets of all the economy.Thus, Housing and Utility is a typical difficult organizational and economic system possessing characteristic features of openness, nonlinearity and dissipativity. In this re-gard, the reasonable approach to Housing and Utility development assumes the need to account for the principles of systemacity, focus and complexity, and also can be based on the existing in the theory and practice of management methodology by difficult organizational and economic systems.Now Housing and Utility development and financing investment programs of the municipal complex organizations is carried out according to the relevant Federal law, according to which the establishment system of limit indexes of change of tariffs and investment extra charges to tariffs for services of the organizations of a municipal complex. Also, innovative ways of energy efficiency increase and decrease in wear of funds is an attempt of the state to develop effective mechanisms of attracting private funds from investors.

    Research and practical guidelines have many implications for how to structure a health economic study. A major focus in recent decades has been the quality of health economic research. In practice, the factors influencing a study design are not limited to the quest for quality. Moreover, the framework of the study is important. This research addresses three major questions related to these framework aspects. First, we want to know whether the design of health economic studies has changed over time. Second, we want to know how the subject of a study, whether it is a process or product innovation, influences the parameters of the study design. Third, one of the most important questions we will answer is whether and how the study's source of funding has an impact on the design of the research. To answer these questions, a total of 234 health economic studies were analyzed using a correspondence analysis and a logistic regression analysis. All three categories of framework factors have an influence on the aspects of the study design. Health economic studies have evolved over time, leading to the use of more advanced methods like complex sensitivity analyses. Additionally, the patient's point of view has increased in importance. The evaluation of product innovations has focused more on utility concepts. On the other hand, the source of funding may influence only a few aspects of the study design, such as the use of evaluation methods, the source of data, and the use of certain utility measures. The most important trends in health care, such as the emphasis on the patients' point of view, become increasingly established in health economic evaluations with the passage of time. Although methodological challenges remain, modern information and communication technologies provide a basis for increasing the complexity and quality of health economic studies if used frequently.

  13. ECONOMIC AND LEGAL ASPECTS OF THE PLANNED DAMAGES ACTIONS FOR THE BREACHES OF EC ANTITRUST LAW

    2010-09-01

    Full Text Available This paper investigates the planned damages actions for breaches of EC antitrust law in order to assess their impact on consumer welfare. It first examines the current legal situation and concurs that the European Union needs to regulate damages actions for breaches of EC antitrust law so that a higher number of consumers could be compensated for their losses. This paper then discusses the main legal provisions proposed by the Commission in the Green and in the White paper on damages actions for breaches of EC antitrust law. The analysis of these proposed legal provisions is done using arguments specific to the economic analysis of law. It is demonstrated that most of these proposed legal provisions will enhance consumer welfare but that there are also proposed legal provisions which will damage consumer welfare. The paper concludes that the planned damages actions for breaches of the EC law will be an improvement compared to the current situation. However, the Commission should amend some of the proposed legal provisions in order to help consumers further.

    In 2008, Cedigaz, an association with approximately a hundred international members from the natural gas industry, took interest in natural gas production in the United States. This production has grown steadily since 2005 despite the assumptions that domestic resources were being depleted and that major investments were needed in re-gasification terminals. The increasing price of natural gas on the American market till mid-2008 was thought to justify all the efforts being made for production. The economic downturn at the end of 2008 and during all of 2009 quickly brought prices back to a more moderate level. Nonetheless, production has still grown and even reached its 1973 level for the first time since. This can be set down to a radical change in the access to unconventional resources, mainly shale gas, at a lower cost thanks to new technology and improved productivity. What are the characteristics of this change? What is its impact on international markets and, in the long run, at a worldwide scale?

    General recommendations for a reference case for economic studies in rheumatic diseases were published in 2002 in an initiative to improve the comparability of cost-effectiveness studies in the field. Since then, economic evaluations in osteoarthritis (OA) continue to show considerable heterogeneity in methodological approach. To develop a reference case specific for economic studies in OA, including the standard optimal care, with which to judge new pharmacologic and non-pharmacologic interventions. Four subgroups of an ESCEO expert working group on economic assessments (13 experts representing diverse aspects of clinical research and/or economic evaluations) were charged with producing lists of recommendations that would potentially improve the comparability of economic analyses in OA: outcome measures, comparators, costs and methodology. These proposals were discussed and refined during a face-to-face meeting in 2013. They are presented here in the format of the recommendations of the recently published Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement, so that an initiative on economic analysis methodology might be consolidated with an initiative on reporting standards. Overall, three distinct reference cases are proposed, one for each hand, knee and hip OA; with diagnostic variations in the first two, giving rise to different treatment options: interphalangeal or thumb-based disease for hand OA and the presence or absence of joint malalignment for knee OA. A set of management strategies is proposed, which should be further evaluated to help establish a consensus on the "standard optimal care" in each proposed reference case. The recommendations on outcome measures, cost itemisation and methodological approaches are also provided. The ESCEO group proposes a set of disease-specific recommendations on the conduct and reporting of economic evaluations in OA that could help the standardisation and comparability of studies that evaluate

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

    Full Text Available Relevance and purpose of the study. Under modern conditions, the share of loss-making enterprises of the coal industry is still high. This brings the solution of the problem of improving the efficiency of their activities up to date. It also determines the purpose of this research. Research methods: scientific generalization, system and factor analysis, and statistical modeling are used in the present work. Results. The article discusses the economic and theoretical aspects of planning the effective activities in the coal industry. The paper analyzes the elasticity of the unit cost price in terms of its labor productivity. It also deals with the elasticity of the volume of output in terms of labor productivity. This indicates that the existing coal mining technologies have, to some extent, exhausted their advantages in the coal industry. They require a change on the achieved level of the capital-labor ratio. It is recommended to strive to ensure advanced ratio of growth of labor productivity of workers compared to the growth rate of unit costs. This should be done at the introduction of a new technology at the enterprises of the coal industry. The advanced ratio of growth in output compared to the growth rate of labor productivity of workers should also be guaranteed. The early growth rate of revenue from sales compared to the growth rate in total costs of production should be provided. The advanced ratio of profit growth compared to the growth rate of revenue from sales has to be provided as well. It is proven that for coal industry enterprises the type of competitive advantages called “the lowest costs” can be the only acceptable one in comparison with other types. We have considered the requirements to the new developed technologies for coal mining. They are as follows: the value of marginal profit in the planned period should be more than the fixed costs of the enterprise; the value of marginal profit in the planned period should be more

    Full Text Available As canine rabies control in Africa and Asia transitions from research-led proof-of-concept studies to government-led programs for elimination, experience and evidence of their impact and costs must be shared for the benefit of future programs. The Ilocos Norte Communities against Rabies Exposure project was implemented in April 2012 by the provincial veterinary and health offices and supported by many other partners. It delivered a comprehensive dog vaccination program and increased awareness of the need for postexposure prophylaxis (PEP, aiming to eliminate human and animal rabies cases from Ilocos Norte by 2015. Prior to the intervention, confirmed rabies cases in dogs were between 19 and 50 per year (2008–2011. The primary outcome of the project was a reduction in rabies cases in both dogs and humans to 0 in 2014 and 2015, which has subsequently been maintained. Animal bite consultations increased significantly during the project. Economic data for the dog vaccination and PEP components of the project were collated for two sites: Laoag City (an urban setting and Dingras Municipality (a rural setting between 2012 and 2014. The average programmatic cost of vaccinating each dog was $4.54 in Laoag City and $8.65 in Dingras, and costs fell as the project reached more dogs. The average costs of providing PEP were $69.72 per patient and $49.02 per patient for the two sites, respectively, again falling as the project reached more people. External donor contributions contributed less than 20% of dog vaccination costs and less than 1% of PEP costs. The project demonstrated that rabies elimination can be achieved in a short period of time, with concerted effort across multiple sectors. A lack of clear dog population estimates hampered interpretation of some aspects of the programme. From 2016, the provincial government has assumed complete responsibility for the programme and must now continue the vaccination and surveillance efforts. Although

    The present study discuss the economic and marketing aspects for the establishment of food irradiation facility in Domietta harbour and the effect of various parameters on unit processing costs. This study is concerned with carrying out an economic evaluation for the application of food exports from Domietta harbour. The study has been carried out according to the approach applied in the evaluation of economic projects and also considering the requirements of technology projects for food preservation.The study is divided into two sections.The first section: concerned with the marketing and technical aspects where the suitable commodity mix was determined for the agricultural crops which are proposed for irradiation. The marketing study comprised determination of the commodity mix, distributions of the commodity mix all over the year according to the harvest seasons and determination the type and capacity of the source. The second section: comprises the economic analysis according to the method adopted by the International Bank for Development taking into consideration the effect of applying radiation technology on the national income. It provides a model for calculating specific unit processing costs by correlating the known capital costs with the annual operation cost and annual throughputs. The cost benefit of the proposed food irradiation facility was analyzed taking into account the cost of the capital investment, operation cost and other additional parameters. The results of this study showed that there is no economic feasibility for the establishment of an irradiation facility for the radiation treatment of food commodities exported from Domietta harbour

    The German Environment Agency (UBA) accompanies the debate on fracking for years. Two major reports on risks and environmental impacts regarding the exploration and exploitation of unconventional natural gas, in particular shale gas have been published. On the basis of these studies as well as on scientific evidence UBA considers ecological barriers as a sustainable means to minimize the risks to environment and human health. 1) Recent studies show that the contamination of shallow aquifers by rise of fluids through natural faults or artificially created fractures is extremely unlikely. However, activities on the surface and lack of wellbore integrity pose threats and substantial risks for the quality of shallow aquifers. 2) The need for thorough groundwater monitoring is fully accepted, yet its range and design is subject to discussion. 3) Formerly, analysis and mass balances of flowback and produced water have been insufficient, thus there is a lack of exact information on proportions of frac-fluids, flowback and formation water respectively, as well as data on possible reaction products. 4) Currently, neither on national nor on European level best reference techniques (BREF) for the treatment and disposal of flowback and produced water are available. 5) In addition, land consumption, emission of greenhouse gases, and induced seismicity are major issues. UBA recommends amongst others the implementation of an environmental impact assessment (EIA) for fracking activities, the prohibition of fracking in water protection areas as well as their catchments, and the disclosure of all frac-fluid chemicals within a national chemical registry. To achieve these objectives the German Environment Agency suggests a step-by-step approach. The paper will present the main results from the studies and the recommendations of the German Environment Agency regarding hydraulic fracturing for unconventional gas exploitation.

    There is growing societal pressure, expressed through government legislation and consumers' purchasing choices, to abolish livestock systems considered detrimental to farm animal welfare. Such systems include farrowing crates, which are behaviourally and physically restrictive for sows. Therefore, identifying less restrictive farrowing systems for commercial implementation has become an important focus of pig research. Despite numerous attempts to develop indoor alternatives to crates, there is as yet no universal acceptance of such systems at the commercial level. The primary concern is piglet survival, because often favourable figures are reported at the experimental level, but not replicated in commercial evaluation. Alternative farrowing systems should equal or surpass survival levels in conventional systems and perform consistently across a range of farm circumstances for widespread commercial implementation. In addition, it is important that alternatives consider ease of management, operator safety and economic sustainability. Utilising a large database of literature, 12 existing alternative indoor systems were identified and compared against each other, conventional crates and outdoor systems. An assessment of how well alternative systems satisfy the design criteria for meeting animals' biological needs was carried out by developing a welfare design index (WDI). The physical and financial performance of these systems was also evaluated and summarised. The derived WDI yielded values of 0.95 for conventional crates, with higher scores for commercial outdoor systems of 1.10 and indoor group farrowing or multi-suckling systems (e.g. Thorstensson = 2.20). However, the high total piglet mortality (23.7% ± s.e. 2.26) in indoor group systems compared with conventional crates (18.3% ± s.e. 0.63) and outdoor systems (17.0% ± s.e. 2.05), together with the added capital cost (92% more than conventional crates, 249% more than commercial outdoor huts), mainly as a

    mechanisms to protect domestic producers have been offered. Changes in the legislative framework of Ukraine, which will help to improve the practice of defending the interests of national producers in compliance with WTO rules, have been proposed. Special attention is paid to the issues under discussion by WTO committees and the impact that will have the decisions taken in these committees on the WTO member countries. The main objectives of participation of WTO member countries in the work of these committees have been systemized and the main benefits of active participation in their work have been indicated. The practical significance. The data obtained can be used by public authorities of both Ukraine and other countries that have recently acceded to the WTO in order to improve the use of institutions and mechanisms created by this organization for the realization of their national economic interests.

    Nowadays, small size UAVs (Unmanned Aerial Vehicles) have reached a level of practical reliability and functionality that enables this technology to enter the geomatics market as an additional platform for spatial data acquisition. Though one could imagine a wide variety of interesting sensors to be mounted on such a device, here we will focus on photogrammetric applications using digital cameras. In praxis, UAV-based photogrammetry will only be accepted if it a) provides the required accuracy and an additional value and b) if it is competitive in terms of economic application compared to other measurement technologies. While a) was already proven by the scientific community and results were published comprehensively during the last decade, b) still has to be verified under real conditions. For this purpose, a test data set representing a realistic scenario provided by ETH Zurich was used to investigate cost effectiveness and to identify weak points in the processing chain that require further development. Our investigations are limited to UAVs carrying digital consumer cameras, for larger UAVs equipped with medium format cameras the situation has to be considered as significantly different. Image data was acquired during flights using a microdrones MD4-1000 quadrocopter equipped with an Olympus PE-1 digital compact camera. From these images, a subset of 5 images was selected for processing in order to register the effort of time required for the whole production chain of photogrammetric products. We see the potential of mini UAV-based photogrammetry mainly in smaller areas, up to a size of ca. 100 hectares. Larger areas can be efficiently covered by small airplanes with few images, reducing processing effort drastically. In case of smaller areas of a few hectares only, it depends more on the products required. UAVs can be an enhancement or alternative to GNSS measurements, terrestrial laser scanning and ground based photogrammetry. We selected the above mentioned

  7. Some aspects of socio-economic determinants of mortality in tropical Africa.

    Measurements of mortality levels and trends continue to be inadequate in Africa, largely because of the lack of reliable and adequate information on deaths. A series of estimates depicting mortality levels and trends has been prepared by demographers, different kinds of data and employing different estimation procedures, but knowledge of the "true" structure of mortality in tropical Africa is virtually nonexistent. Because of these problems only a "bird's eye view" of the prevailing situation in tropical Africa is presented. The discussion -- directed to mortality by sex and age, by residence, and by cause -- is based on secondary and fragmentary data. Socioeconomic and cultural determinants of mortality are also examined. Available information on male and female mortality indicates that the death rates for males are higher than they are for females. Early childhood mortality (1-4 years) in tropical Africa is relatively high compared with the other age groups, including infants. Mortality differentials have been noted among geographical and administrative units and subdivisions of populations within the various countries of tropical Africa. Also, urban dwellers enjoy a higher expectation of life at birth than do rural dwellers. Communicable diseases are the main killers in tropical Africa. Persistent poverty and malnutrition, poor housing, unhealthy conditions in the growing cities, nonexistence of health facilities in the rural areas, rapid population expansion, and low levels of education are among the factors impeding progress in reducing mortality in tropical Africa. The need exists to express development goals in terms of the progressive reduction and eventual elimination of malnutrition, disease, illiteracy, squalor, and inequalities. Future trends in mortality in tropical Africa may depend more than they have in the recent past on economic and social development.

    Full Text Available The purpose of this study is to consider strategies and options for improving the efficiency of the pressure boosting station No. 4 in Gachsaran oil reserve (which is located in south-western of Iran. In order to achieve these objectives, the four rational options from technical and operational views were proposed and then these options went through an economic assessment. Next, by onsidering the other important criteria based on technical conditions (due to the necessity of evaluating other criteria beside economic criterion, decisionmaking techniques were employed. The results of economic evaluation show that the present value of the costs of option 1 is lower than other options and option 2 provides poorer economic status and is ranked last among the recommended options. Therefore, option 1 is 30.5 percent better than option 2. In addition, employing MCDM Technique allocated maximum weight (0.320 to economic evaluation criterion and again option 1 -with the highest weight (0.354- was the best possible option. Regards to purpose of this study, using techno-economical approach leads practitioners to decide based on technical and economic facts simultaneously.

    Full Text Available Health, demographic and environmental consequences of 1998 and 2008 economic crises for the Ural Federal District are considered in the paper. Regional resilience is defined as the ability of a regional socio-economic system to withstand, absorb or overcome an internal or external economic shock. The quantitative analysis of regional resilience of the subject entities of the Ural Federal District is based on two interrelated dimensions: resistance, those are the vulnerability or sensitivity of a regional socio-economic system to disturbances and disruptions; and the speed and extend of recovery from such a disruption. Because resilience as a concept captures resistance to the shock and recovery from it, resistance indexes and recovery indexes are used for assessing the impact of regions to recessionary shocks. Three sets of resilience indicators were used: economic, environmental and medico-demographic ones. The main criteria for selecting resilience indicators were their robustness as a measure of the territorial impact of the economic crisis and availability of long time series. Special attention is paid to the question identification of the qualitative and quantitative factors, which form the territorial characteristics enabling some regions to resist, or move out of, economic downturn more effectively than others. Unfortunately, a valid answer to the question why some regions are more able to withstand an economic downturn than others, or are able to recover faster, cannot be given at present. Resilience to an economic shock does not necessarily imply that the economy is otherwise strong and performing well over the longer-term. Regions that experience strong economic growth prior to a shock may appear to be less resilient. Such components of the regional socio-economic system as reserves of natural resources, sectoral structure of regional economy, skills of population, diversified economy and quality of governance do not define uniquely

    Czechoslovak uranium industry became a myth between 1945 and 1990. It connected main features of planned economic system and ideological rules of a totalitarian regime. Its development was connected with declaration of uranium medical use at the end of the 1940s. In the 1950s and 1960s this was replaced by its use for 'peace-keeping' needs and after 1970 with its use for developing nuclear energy supply. Anyhow its production has always been much higher then the NPPs demand. Between 1945 and 1999 the total production of Czechoslovakia (almost entirely of the Czech Republic) was almost 108 thousand metric tons of uranium. Based on two-sided long-term agreements almost 100 thousand metric tons of it was exported to the USSR. Export of pre-concentrated ore started in 1945 and continued till 1975. During the time this was slowly replaced by export of uranium in chemical concentrate between 1953 and 1990. Industrial uranium production started in 1945 in Jachymov area. This region had been famous in previous silver mining (five-element formation - Ag, Co, Ni, Bi, U). Discovery of radium and polonium by Curies in 1898 set the foundations of a new, use of uranium ores, which were used only for dyeing in glass and pottery until that time. The Jachymov area was not of a very high industrial importance because of its resources, but of a high political influence. There were practically no operating uranium mines in the Soviet Union zone of influence in 1945. Therefore the Jachymov mines were occupied by the Red Army on September 11, 1945 and total production since that time was shipped to the Soviet Union. Total production between 1945 and 1964, when the mines were closed, was 7000 tonnes of uranium. In comparison with the northern part of the Krusne hory (Ore Mountains), the former GDR part, the total production was less than 10%. The second production area was situated about 30 km south of Jachymov. It was Horni Slavkov. Its total production was only 2700 tonnes of uranium

Methods discursive comparative general scientific methods of analysis and synthesis ethnosociological survey. nbsp Results the Halal food market of Islamic economy is a subject of scientific and practical interest for several reasons it is a dynamically developing promising market with great potential and development opportunities. To achieve the stated objective the authors analyzed the studies of domestic and foreign scientists on the essence and organization features of the Islamic economy. Conclusions were formulated about what Halal food is primarily associated with the complex religious not gastronomy requirements. The analysis of the food concepts in the Islamic culture has showed that the fundamental characteristic of food is its permissibility. To determine the concepts of Halal products existing among the Muslims a Halal products market research was conducted in Kazan. First of all to determine the ethnoreligious profile of the Halal products consumers the structure of ethnic populations was analyzed the change in their numbers over the last 20 years and the reasons for such change. The next part of research involved conducting a poll among men and women ndash Tatars aged 18 to 30 years. The main aim of the survey was to determine the causes of food behavior of the population. According to the survey results the key conclusion was formulated that for this age group the choice of food is not determined by religious considerations but by the desire for healthy and proper nutrition. The survey results allowed to compile a list of recommendations for improvement of the functioning of the Halal market subjects and the state and municipal bodies. Scientific novelty for the first time an interdisciplinary approach was used at the intersection of economics sociology and anthropology for this research

    Full Text Available The EVA indicator has been constructed in the recent past as a reaction to requirements of the new economic environment. As the EVA indicator has been introduced by Stewart Stern & Co. in the early nineties, past two decades many economists have been discussing the pros and cons of EVA application as well as various adjustments needed to calculate some relevant result. A range of attitudes to the adjustments to accounting data towards economic data exist there. As the indicator of economic value added is considered to be a criterion of company’s real economic performance it is necessary to be very careful at applying encouraged adjustments. In this article, the authors compare and discuss these adjustments advised in order to reach some ideal number. Accounting differences of US GAAP, IFRS and Czech Accounting Standards are taken into consideration.

    Achieving economic competitiveness as compared to LWRs and other Generation IV (Gen-IV) reactors is one of the major requirements for large-scale investment in commercial sodium cooled fast reactor (SFR) power plants. Advances in R&D for advanced SFR fuel and structural materials provide key long-term opportunities to improve SFR economics. In addition, other new opportunities are emerging to further improve SFR economics. This paper provides an overview on potential ideas from the perspective of thermal hydraulics to improve SFR economics. These include a new hybrid loop-pool reactor design to further optimize economics, safety, and reliability of SFRs with more flexibility, a multiple reheat and intercooling helium Brayton cycle to improve plant thermal efficiency and reduce safety related overnight and operation costs, and modern multi-physics thermal analysis methods to reduce analysis uncertainties and associated requirements for over-conservatism in reactor design. This paper reviews advances in all three of these areas and their potential beneficial impacts on SFR economics.

  3. Does engineering education need to engage more with the economic and social aspects of sustainability?

    Fitzpatrick, John J.

    2017-11-01

    This paper questions if engineering educators are producing engineers that are accelerating humanity along an unsustainable path. Even though technology and engineering are important drivers in trying to move humanity towards an environmentally sustainable paradigm, the paper suggests that maybe the most important levers and challenges lie in the economic and social domains. Short case studies of energy efficiency, the experience of the industrialist Ray Anderson and the authors own reflection of teaching chemical engineering students are used to highlight this. Engineering/technological innovation may not be enough and is often counteracted by the rebound effect and the current dominant neoclassical economic paradigm. The paper discusses what engineering educators can do to produce sustainability informed engineers who are better able to engage with the economic and social dimensions of sustainability. Some suggestions for engaging engineering students with the economic and social dimensions of environmental sustainability are provided. Engineers must somehow find ways, not just to influence technological levers (which are very important) but also to influence economic and social levers so that changes in economic and social behaviours can complement and facilitate technological change in moving humanity to an environmentally sustainable paradigm.

    2012-12-01

    Full Text Available This article focuses on development of Russian-Lithuanian economic ties. The research and practical significance of this study lies in the identification of the sources of modern Russian-Lithuanian economic cooperation and the prospects of future mutually beneficial economic relations. The first attempt at establishing economic relations was made in 1919. However, young Lithuanian Republic gravitated towards the West, severing ties with the Russian market. However, the initiatives of Lithuanian authorities did not result in successful state building, and the economic situation remained unchanged. The USSR leadership made an effort to improve the living conditions in post-war Lithuania. There were some mistakes made in the relations with the local population that resulted in Lithuanians’ resistance to sovietisation. However, in the conditions of post-war restoration of national economy and acute deficit of material and human resources, the Soviet leadership managed not only to reform and develop a socialistic economy in Lithuania but also to turn it into an industrial republic with developed agriculture and modern manufacturing facilities, whose major industries manufactured products used in nuclear and space technologies, aviation and navigation. The research shows that the post-Soviet period led to a dramatic change in Russian-Lithuanian economic relations; however, these relations retained potential for future development.

    1983-01-01

    The original choices of thermal reactors and fuel cycles were largely determined by specific national circumstances and by experience and facilities acquired from defence-related programmes. These led to the development of LWRs in the USA and to the natural uranium/gas/graphite system in the United Kingdom and France, while Canada selected the HWR. Most countries with nuclear power programmes saw the plutonium-fuelled fast reactor, with its breeding potential, as the means to ensure that exhaustion of economic uranium resources would not prematurely curtail the contribution of nuclear power to world energy supplies. Fuel reprocessing was essential to this fuel cycle or indeed to other recycling options to make better use of the available uranium; it was also favoured for waste management reasons. Early expectations of nuclear power growth suggested that a transition from thermal to fast reactors would occur during the present century but the urgency has been reduced by world economic recession, slower increases in nuclear capacity and the continued availability of supplies of low-priced uranium. Reprocessing costs have risen and economics of scale favour large plants, which are therefore most likely to be built in countries with substantial thermal reactor capacities; these countries will be able to provide reprocessing services to others. As the ultimate strategic need for fast reactors has not been reduced by this slowdown it is important to continue the development and demonstration of fast-reactor technology and the associated fuel cycles. Uncertainties in future fuel prices mean that it could be advantageous to introduce fast reactors as soon as they become an economic, although not necessarily the most economic, choice. Notably, fast reactors may be installed initially when and where they become economic compared to coal-fired generation, in order to lay the foundation for more rapid expansion when economic break-even with thermal reactors occurs.

    From the early days of philosophy, ethics and justice, there is wide consensus that the constancy of the laws establishes the legal system. On the other hand, the rate at which we accumulate knowledge is gaining speed like never before. Due to the recently increased attention of academics to climate change and other environmental issues, a lot of new knowledge has been obtained about carbon management, its role in nature and mechanisms regarding the formation and degradation of organic matter. A multidisciplinary techno-economic assessment of current composting standards and laws that took into account the current state of knowledge about carbon management was carried out as a case study. Economic and environmental damage caused by outdated laws was revealed. In addition, it was found that the introduction of the best composts into the market is permitted, causing additional negative environmental as well as economic impacts.

    The results of analysis of the economic benefits of five reconstruction variants are presented for a hypothetical industrial heating plant equipped with 3 boilers with a steam output of 120 t/h each, providing a total power of about 355 MW. The reconstruction was aimed at reducing the emission of pollutants to below the regulatory limits. The economic effectiveness was assessed in terms of the specific cost of heat in overheated steam for brown coal, black coal, natural gas, and mazut. The option consisting in reconstruction of the brown coal fired boiler to low-sulfur black coal without desulfurization emerged as the economically optimal alternative. Second to it was the option identical with the first but augmented with a dry additive desulfurization equipment. The brown coal fired boiler equipped with a semidry desulfurization equipment ranked as the third. (J.B.). 3 tabs., 6 figs

    2015-08-01

    Full Text Available The paper provides an insight into the dominant trends of contemporary evolutionary economics and outlines the important issues related to the articulation of this approach in thinking about the economy. The paper also affirms a proposition on institutions as carrier structures of socio-economic evolution, whose numerous effects at the societal level are decoded through the coordination function. In addition to the market, the process of coordination also employs other non-market institutional structures, whose profile and operational principles are the product of the trajectories of cultural and historical evolution, different among social orders. Projects aimed at the transformation of the economic system are to be sensitized to an objectively conditioned diversity of the institutional structures of the world economy, and in this sense, should be very careful in the installation of „universal” reform solutions.

    Full Text Available Gender aspects of the access to economic resources within the processes of terrritorialization are important at macro-level for the designing processes of sustainable rural development, as well as at the micro-level, for shaping livelihoods of men and women in rural areas. The research is based on the assumption that access to economic resources is gendered. Starting from the findings of previous researches (Blagojević, 2010, Babović and Vuković, 2008, Trajković, 2002, Korać, 1991 on gender relations in rural areas, the research presented in this paper is motivated by intention to get deeper knowledge about gender aspects of access to economic resources throughout the processes of territorialization (Battaglini, 2014. The process of territorialization is the process of 'embedding' actors in the place of living, which unfolds through their interactions with nature and other resources available for production and securing livelihoods. Territorialization patterns, the access to endogenous and egzogenous resources available in the given territory (Stimson, Stough and Njikamp, 2011 are important elements of positioning of men and women in the processes of rural development. Qualitative research findings indicate that gender and generation differences in the territorialization patterns are present in the key phases of symbolization, reification and organization, and they are influenced by specific norms and values as well as power relations.

    Full Text Available Industrial Engineering is a field that has attracted the attention, especially because of its synergy with other areas of knowledge. In order to think about education in Industrial Engineering it is necessary to consider its relationship and interdependence with other areas. In this way, the relationship with Economics is considered. Although the objectives of both areas and their methods are distinct, they are related in many points. So, the contribution of study economy is directly related to the ways these topics will be studied in the Industrial Engineering courses. It is also implied how these topics will be chosen to be presented. The present paper’s objective is to analyze the teaching of Economics in the Industrial Engineering courses inBrazil. In order to achieve this objective, a documental research has been conducted, using the Content Analysis technique applied to the Teaching Plans of the disciplines covering the Economics contents in 15 Institutions. It has been concluded that the topics covered in the courses are of a broad nature, with emphasis in theoretic content of Economics. Furthermore, the strategies used in classroom, as well as the assessment methods are still of traditional nature.

    Full Text Available In this paper we proposed to investigate the spread of poverty phenomenon on the global scale. Also we examined the causes and the efects of unequal distribution of global wealth, emphasing the impact of economic globalization on the deepening of poverty at the international comunity level. In the contemporary context of economic globalization the poverty is a scourge of the international community, that marks a dangerous gap between the many poor and the few rich. On the other hand, the poverty can be rightly considered the deprivation of population or certain population groups of welfare. In generally, for the common man, poverty means hunger, misery and diseases. Also, the poverty is an economical-legal phenomenon. The economic component of poverty consist in the deficiency of resources to ensure a decent standard of living and the access to basic services (health, education etc., while the legal dimension is reflected in the reduced possibility of a person or population groups to benefit from the civil rights and other fundamental rights, as well as the right to lead way of life which he desires or values.

    Full Text Available Authors analyze the problem to find the optimal policy options to stimulate economic growth in modern conditions. They point out three possible options for such policy according to the different structural priorities. This point causes the question of the extent to which the proposed policy approaches to stimulate economic growth correspond to real economic trends. The solution of this problem is possible only on the basis of the empirical study analysis results. Also it is necessary to take into account the regional dimension related to the fact that the various sectors of the economy linked to the various regions. According to this fact one may point out Russian regions with the predominance of the mining industry, manufacturing industry and services. Authors exploit panel dataset on 80 Russian regions for the period 2005-2014 to analyze the relationship between annual shares of sectors in output and employment and per capita gross regional growth. Results indicate that regions with a higher share of manufacturing and mining both in terms of output and employment grow slower during the reporting period. The impact of services on growth is somewhat paradoxical: regions with bigger shares of healthcare and education in output growth faster, but a bigger share of this sector in employment, as much as expanding of the labor share of these sectors impede growth. Possible reason for this paradox is that the high proportion of services in the regions-leaders (especially the share of total employment reflects not the degree of their development, but the development of the public sector in relatively poor regions. The results show that neither manufacturing nor mining and services are not the engines of economic growth that can ensure sustainable development of the whole economy. Authors point out that it is necessary to conduct multivariate policies to stimulate economic growth, which is based on the various configurations of developmental actors

    The basic strategy of Russian nuclear energy is propagation of a closed fuel cycle on the basis of fast breeder and thermal reactors, as well as the solution of the spent nuclear fuel accumulation and resource problems. The 3 variants of multiple Pu and U recycling in Russian pressurized water reactor concept reactors on the basis of Regenerated Mixture of U, Pu oxides (REMIX) reprocessing technology are considered in this work. The REMIX fuel is fabricated from an un-separated mixture of uranium and plutonium obtained during spent fuel reprocessing with further makeup by enriched natural U or reactor grade Pu. This makes it possible to recycle several times the total amount of Pu obtained from the spent fuel. The main difference in Pu recycling is the concept of 100% or partial fuel loading of the core. The third variant is heterogeneous composition of enriched uranium and uranium-plutonium mixed oxide fuel pins in one fuel assembly. It should be noted that all fuel assemblies with Pu require the involvement of expensive technologies during manufacturing. These 3 variants of the full core loadings can be balanced on zero Pu accumulation in the cycle. The various physical and economical aspects of Pu and U multiple recycling in selected variants are presented in the given work. The better results in natural uranium savings can be achieved for the standard REMIX(UOX) approach. The usage of regenerated materials in thermal power reactors gives not more than 30% saving of natural uranium consumption. It is important to note that the use of REMIX technology in the closed fuel cycle is more expensive than the open fuel cycle with direct spent fuel disposal. It is also important to see that uranium multiple recycling in the REMIX fuel form or using the re-enrichment process leads to the degradation of the uranium isotope composition. The "2"3"6U and "2"3"2U concentrations in the fuel are increasing and the regenerated uranium treatment becomes more complicated

    Full Text Available The establishment and application of economical levels demand a procedure to find with precision the insects population in a given moment. In the integrated management of plagues is not allowed the idea that any insect which is feeding from a part of plants requires a control action, that is why it is very important to determine the real effect that this insect population causes to the cultivation. Any decrease in the crop, constitutes a real waste of time; but when the economical level is defined, it is included an additional factor which is the measure cost of the plagues control. The determination of damages of levels is very important for economists, farming experts and specialists; while for producers is very significant its implementation with the objective to count with a sustainable and beneficial agriculture.

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

    2016-01-01

    Full Text Available Due to the challenge of rising public awareness of environmental issues and governmental regulations, green supply chain management (SCM has become an important issue for companies to gain environmental sustainability. Supplier selection is one of the key operational tasks necessary to construct a green SCM. To select the most suitable suppliers, many economic and environmental criteria must be considered in the decision process. Although numerous studies have used economic criteria such as cost, quality, and lead time in the supplier selection process, only some studies have taken into account the environmental issues. This study proposes a comprehensive fuzzy multicriteria decision making (MCDM approach for green supplier selection and evaluation, using both economic and environmental criteria. In the proposed approach, a fuzzy analytic hierarchy process (AHP is employed to determine the important weights of criteria under vague environment. In addition, a fuzzy technique for order performance by similarity to ideal solution (TOPSIS is used to evaluate and rank the potential suppliers. Finally, a case study in Luminance Enhancement Film (LEF industry is presented to illustrate the applicability and efficiency of the proposed method.

    2016-01-01

    Full Text Available This paper deals with the assessment of cultivation of bread wheat (Triticum aestivum L. and oat (Avena sativa grown in Central Europe within the conventional and organic farming systems in terms of greenhouse gas emissions and economic profitability. Organic farming may be one of the tools for mitigation of greenhouse gas emissions from agricultural production. In the context of crop production, cereals rank among the most commonly grown crops and therefore bread wheat and oat were chosen. The Climate change impact category was assessed within the simplified LCA method and the production of greenhouse gas emissions expressed in CO2e per the production unit was calculated. Economic balance of the cultivation of monitored cereals was compiled based on the yields, farm gate prices and costs. On its basis, the cultivation of wheat within the organic farming system appears to be the most profitable. From an environmental point of view, the emission load of the organic farming system is reduced by 8.04 % within the wheat production and by 15.46 % within the oat cultivation. Therefore, the organic farming system in the Czech Republic appears to be more environmentally friendly and economically efficient within the cereals production.

    Full Text Available The paper examines the development of economies in the sub-Saharan region. It aims to identify particular development trends specific to the region. That means identifying changes which have occurred in the past five decades in following areas: development of the GDP value ​​and structure, growth in the value of foreign trade, demographic growth, and changes in the value of GDP per capita. The results of the analysis show very constrained economic power of sub-Saharan region. Not only weak economy of the region but also a significant population growth is a problem. Increasing production and trade does not contribute effectively to elimination of high level of poverty and malnutrition which remains a long-term problem of the sub-Saharan region. In real terms, the GDP per capita was growing by less than 1 % in the period 1961–2010. Sub-Saharan region is highly dependent on cooperation with other world regions in its effort to increase economic growth and to improve the economic situation of own population. The GDP growth is thus very sensitive to GDP development in Europe and North America. Concerning the foreign trade, development of sub-Saharan trade is dependent on regions of the Southern and Eastern Asia, and Europe.

    Full Text Available The only possibility to ensure a high rate of growth of economic efficiency of production is a result of transition to a predominantly intensive type of development, especially for domestic enterprises in current conditions. The article considers, which concrete factors of the external environment of enterprise impact its activity in the present time and on the territory of Ukraine, and also substantiates the necessity of transition to the mode of «intensification». Scientific novelty consists in approbation of the method of research of the degree of intensification of activity on the example of one of the enterprises of Kharkiv, carrying out foreign economic activity. The system of the scientific and special methods was used: system approach; methods of analysis and synthesis of grouping; economic-mathematical method – the method of analysis of production intensification – to determine the degree of intensity/extensiveness of production at the researched enterprise. The calculations allowed to determine that the relative saving of the aggregate resources at the researched enterprise, using this method, amounted to more than 16 million UAH. Thus, it is possible to speak about expediency of use of the presented method in practice, especially in view of the current condition of enterprises of Ukraine.

    1987-07-01

    Changing demographic and economic conditions in the US require that attention be given to some of the intergenerational equity features of government policy. In particular, social insurance programs and public debt leave public liabilities to future generations. Taken in the aggregate, the effects of rapidly rising public debt and especially social insurance programs are transferring substantial amounts of resources from younger working generations to the expanding generation of retirees. The most crucial element in evaluating the desirability of intergenerational wealth distribution in the long run is the rate of economic growth. A society's monetary, fiscal, tax, and regulatory policies can be more or less conducive to the generation of capital formation, technical change, and economic growth. Policies that influence growth and interest rates will combine with the national deficit to determine how rapidly the debt grows or shrinks. Present accounting procedures are insufficient to provide quantitative answers to the question of what is the impact of a given program on the age-specific distributions of resources. It is important to reconsider the desirability and efficiency of intergenerational redistributions of wealth in the US. It is likely that current policies are not in line with the principles of efficiency, equity, target effectiveness, and cost effectiveness.

    Yabe, Akira; Akiya, Takaji

    1996-01-01

    The results of the economic evaluation of the Super Heat Pump Energy Accumulation System project in Japan are reviewed. It is reported that although the initial costs of super heat pumps are higher than those of conventional systems, the calculated operating costs of a unit thermal energy produced by a super heat pump is reduced considerably. All the various system concepts with thermal/chemical storage were evaluated economically with the exception of the high temperature thermal storage systems using salt ammonia complexes and solvation. These latter systems were not further developed as pilot plants. It is advocated to accelerate the introduction of super heat pumps by facilitating their market introduction. Actual clathrate chemical storage systems have shown that the annual costs are comparable to those of an ice storage system. Clathrate systems will find their way in the market. It is concluded that most of the super heat pump systems and clathrate storage systems will be economic in the future. A big challenge however still exists in further improving the cost effectiveness of heat storage in tanks by reducing their size dramatically (to 1/10th)

    Since fossil fuel resources are limited from the point of view of supply in Iran and on the other hand the pressure due to population growth, have all increased demand for energy in the industry, service and domestic sections. Since the capacity of hydroelectric energy is limited and these capacities will be soon completely used, and using other energy resources as solar energy, wind power, biomass and tidal energy are not economically efficient on national scale, the only choice to gain cheap and clean energy source is to develop multipurpose nuclear power plants for generation of electric power. Since the technical studies have been done on nuclear energy and the subject of peaceful uses of nuclear technology is virgin in this country, therefore, we intended to introduce the usefulness of nuclear technique; and its role in economic development. In this respect, since electric energy is one of the factors that runs the industrial wheel, therefore, the emphasis is placed on the economic generation of electric power through nuclear energy

    The contamination of food and feed by mycotoxins as toxic metabolites of fungi is a risk not only for consumers resulting in various embarrassment regarding health status and well-being, but also for producers, companies and export market on the ground of economic losses and ruined stability of economic trade. As it is given in historical evidence, the contamination of food by mycotoxins is a topic as old as a history of mankind, finding some evidence even in the ancient books and records. Nowadays, the mycotoxins are used in modern biotechnological laboratories and are considered an agent for targeting the specific cells (e.g., defected cells to eliminate them). However, this promising procedure is only the beginning. More concern is focused on mycotoxins as abiotic hazard agents. The dealing with them, systematic monitoring, and development of techniques for their elimination from agricultural commodities are worldwide issues concerning all countries. They can be found alone or in co-occurrence with other mycotoxins. Thus, this review aims to provide widened information regarding mycotoxins contamination in environment with the consequences on health of animals and humans. The inevitability for more data that correctly determine the risk points linked to mycotoxins occurrence and their specific reactions in the environment is demonstrated. This review includes various symptoms in animals and humans that result from mycotoxin exposure. For better understanding of mycotoxin's impact on animals, the sensitivities of various animal species to various mycotoxins are listed. Strategies for elimination and preventing the risks of mycotoxins contamination as well as economical approach are discussed. To complete the topic, some data from past as historical evidences are presented.

  6. Analysis of economic and energy utilization aspects for waste heat aquaculture

    Olszewski, M.; Wilson, J. V.

    1978-01-01

    A waste heat aquaculture system using extensive culture techniques to produce fin and shellfish is currently under investigation at the Oak Ridge National Laboratory. The system uses nutrients in waste water streams to grow algae and zooplankton which are fed to fish and clams. A tilapia polyculture association and the freshwater clam Corbicula are the animals cultured in the system. The investigations were performed to determine the economic feasibility of the system and examine energy utilization in the system. A net energy analysis was performed to identify the energy saving potential for the system. This analysis includes all energy costs (both direct and indirect) associated with building and operating the system. The results of the economic study indicated that fish production costs of $0.55/kg ($0.25/lb) were possible. This cost, however, depends upon the fish production rate and food conversion efficiency and could rise to as much as $1.65/kg ($0.75/lb). Clam production costs were found to be in the neighborhood of $0.37/kg of clam meat ($1.24/bushel). The energy utilization study results indicated that, when all energy costs are included, fish from the aquaculture system may require only 35% of the net energy now required for fish products from the ocean. However, the energy requirements also depend on system parameters and could be as large as the energy required for ocean caught products. Clams can be produced in the aquaculture system using only about 25% of the net energy required by traditional means. The results of the analysis indicate that the system appears to be economically feasible. They also indicate that significant energy savings are possible if waste heat aquaculture products replace ocean caught products.

    Lebeau, A.; Reuter, K. E.

    1980-01-01

    The effects of the development of satellite applications on the orientation of the space effort were examined. The gap between available and exploited technology, the impact of the current economic climate and future trends are discussed. Europe's low level of public funding for its space effort, in comparison to other space powers, and the dangers of complacency regarding Europe's competitiveness in the space market are illustrated. A proposal for the general direction which Europe's future strategy must take if European independence in this field is to be preserved is presented.

    Energy crisis has become one of the most concerning issues throughout the world including emerging developing country like Bangladesh. Scientific community has unequivocally agreed that renewable energy is the only solution to face this challenge. A number of researches on renewable energy (e.g., solar, wind, hydro energy and biogas) have been carried out in Bangladesh. So far, biogas and solar energy has been proved to be the best alternative to meet the daily energy demand. However, Bangladesh could achieve more success with biogas in rural areas if socioeconomic, technical and regulatory issues were addressed appropriately. This study analyzed not only these factors but also (i) the present situation of the biogas production, (ii) ways to improve the efficiency and economic benefits of small-scale or farm-scale biogas production, (iii) existing problem associated with small-scale/farms-scale biogas production, (iv) reason behind not using and not using of biogas by the people nearby the user of biogas, (v) economic benefits of small biogas plants and (vi) the ways to improve efficiency by intervening feed stock quality and composition of the small-scale/farms-scale biogas plants.

    Barnert, H.; Neis, H.

    1987-01-01

    The development of the high temperature reactor in the FRG was opened with the aim of economically producing electricity which might be achieved with the next project works. Moreover, the HTR supplies process heat of very high temperature which may be used with metallic heat exchangers in the range up to 1000 0 C. From these reasons and regarding the world power prospects and the special power situation in our own country, the FRG began to develop methods of upgrading fossil primary energy sources using high-temperature heat from the HTR about 15 years ago. Meanwhile great progress has been achieved in research, development and test works; the modules are developed to a great extent. Economical service is expected for future utilization of selected processes. Problems to be still accomplished are first of all related to system testing as well as further exhaustion of the HTR's temperature potential. The proposed extension of the AVR to some process heat facility offers the possibility of testing the system in a low-cost and accelerated manner. (author)

  14. Economic aspects of recycling U.S. Department of Energy radioactive scrap metal

    Harrop, J.; Numark, N.; MacKinney, J.

    1995-01-01

    The U.S. Department of Energy (DOE) has substantial quantities of scrap metal contaminated with low-levels of radioactivity. What is more important, current DOE Decommissioning and Dismantlement (D and D) plans will generate even more radioactive scrap metal. Disposition of this radioactive scrap metal could result in substantial costs to the DOE, but if certain options are exercised, could result in an economic gain. This paper outlines five basic options the DOE could follow for disposition of its radioactive scrap metal, and then examines the economic consequences of each option. A cost-benefit analysis was used to evaluate each of the five options. Real costs, derived from DOE studies and private industry, formed the basis for all analysis. These include transportation, packaging, processing (melt-refining) prices charged by industry, and burial fees and scrap metal storage facility operating and surveillance costs faced by the DOE. Other potential costs, such as the avoided costs of mining, and other less-well defined factors are assumed imbedded in the prices charged by industry for processing radioactive scrap metal. The results of this analysis show that burial cost is the most significant factor to consider in deciding which RSM disposition option to pursue. Moderate variations in burial costs can dramatically change the outcome of the cost-benefit analysis. (author)

    2016-09-01

    Full Text Available This paper presents the results of a study conducted among pre-service home economics teachers from the Faculty of Education of the University of Ljubljana with different levels of practical experience in teaching. The pre-service Home Economics teachers in the 3rd year of their studies had just completed their first class of teaching experience in contrast to the pre-service teachers from the 4th year of their faculty studies, who had conducted more teaching lessons. The results showed that the 4th-year pre-service teachers had fewer doubts and problems concerning the planning and conducting of a lesson. They also statistically significantly agreed that they are sufficiently prepared to teach than the 3rd-year pre-service teachers are. The results showed that the majority of the pre-service teachers agreed that the feedback from their colleagues was helpful for their professional development. The results suggest the importance of practical teaching experience in the context of professional development and the intention to continue a career in education. However, the results also revealed some critical points in the teacher’s development of competency. The results suggest problems related to the application of theoretical knowledge on the children’s development in practice and problems related to classroom management in specific situations.

    2018-01-01

    Full Text Available The results of supervision which UEFA in 2009 carried out on clubs showed that more than half of a total of 655 European clubs are in debt. Moreover, these are huge debts which are disproportionate with their financial possibilities. The three biggest European clubs were in such financial disarray that they were in two years, treated like other businesses, declared to be bankrupt. That period coincided with the widening of EU legislative powers and in sport issues and with the focus of the Commission on “sound management”. In 2010, UEFA presented a new Rulebook on the licensing of clubs and financial fair play. This Rulebook introduced doing business on “point of financial security” as their basis for the financial sustainability of European clubs. However, from the very beginning of its application its relation with EU legal regulations on competitiveness was disputable. This Rulebook existed in this limbo for 8 years and slowly real effects of its application are starting to be supervised. Namely legal and economic effects were often shown to have an unexpected effect, especially in combination with EU law. The intention here is to observe in detail the Rulebook’s regulations through various prisms: relation to EU legal regulations, its economic effects and the effect on stability and competitive balance.

    2016-12-01

    Full Text Available The second pillar of the Common Agricultural Policy is an important element of support for Polish rural areas, due to the need to improve the competitiveness of agricultural producers, to transform the employment structure, to boost infrastructure development and to implement tasks related to the protection of the environment. Thus, the size of the funds of the Rural Development Programme (RDP for 2014–2020 and their allocation to different tasks is essential for the future of rural areas. The aim of the article was to evaluate the RDP for 2014–2020 from the point of view of the potential economic consequences of its implementation. This rating was made in two areas: the budget, and the construction of selected activities. Data on the budget and the allocation of funds in the new financial period indicate that the RDP limits expenditures on some of the objectives, primarily related to infrastructure and entrepreneurship. The priority actions are, however, pro-investment and modernization, and improving the position of farmers in the food chain. There are also programs of a social nature, aimed at small farms and activities with low added value (e.g. less favored areas, or LFA. Reducing the budget of the RDP forced implementation of some solutions, e.g. degressive payments and limits on the area and economic size of farms; thereby both the smallest and larger farms could be excluded from part of the support.

    Directory of Open Access Journals (Sweden)

    Zemlyanushnov Dmitriy Yur'evich

    2014-09-01

    Full Text Available This work considers economic expediency of using marble fine waste in facing ceramic materials manufacture by three-dimensional coloring method. Adding marble fine waste to the charge mixture reduces the production cost of the final product. This waste has a positive impact on the intensification of drying clay rocks and raw as a whole, which increases production efficiency. Using marble fine waste as a coloring admixture makes it possible to manufacture more environmentally friendly construction material with the use of wastes of hazard class 3 instead of class 4. At the same time, disposal areas and environmental load in the territories of mining and marble processing reduce significantly. Replacing ferrous pigments with manganese oxide for marble fine waste reduces the cost of the final product and the manufacture of facing ceramic brick of a wide range of colors - from dark brown to yellow.

    Full Text Available Scientific studies state that a considerable part of the economic value of crop plant production should be attributed to the free services of pollinating insects. Such calculations are available for several EU and North American countries, and the present paper evaluates the value of pollination services to 19 important Polish crop plants. It is estimated that the market value of 19 entomogamous crops reaches the sum of approx. 7.5 billion PLN (thousand million (approx. 1.8 billion EUR, 39% of this may be attributed to the insect activities, the most important being bees (the service value of approx. 2.5 billion PLN/0.6 billion EUR and dipterans (almost 0.3 billion PLN/ 74 billion EUR. The paper discusses also the challenges and pitfalls of similar estimations and the need for conservation actions directed on crop plant pollinators.

    Bianca Horlemann

    2012-12-01

    Full Text Available In the past and today, Tibetan-Muslim relations in Qinghai and Gansu are often associated with violent conflicts sparked by religious differences or 'interethnic hatred'. A more nuanced study of the history of Tibetan-Muslim relations, however, reveals complexity as well as considerable local difference with regard to how and when contacts were established, maintained, and broken off. Tibetan Muslim encounters were manifold and varied, including interethnic marriages, close business relations, political alliances, and armed conflicts. To illustrate this wide range of encounters, examples chosen for this paper, i.e., the relations between Amdo Tibetans and the Muslim Baoan nationality, the Muslim Ma warlords, and the Chinese xiejia institution, span different eras and localities. This study suggests that Tibetan-Muslim relations were predominantly shaped by socio-economic and political factors rather than by religious differences or 'interethnic hatred' as is often assumed.

  5. State of the art of heat production from biomass taking into account economic and ecological aspects

    1994-01-01

    In the range of solid fuels, the most important biomass energy carrier is wood, followed by straw and, used in single pilot and demonstration projects, so-called energy plants. Due to tax laws, plant oil and ethanol are economically more interesting as liquid fuels. In wood firing, billet wood furnaces and boilers are most common. The product range extends from chimney fireplaces to underjet boilers for timber. Incineration plants with automatic fuel metering systems require pourable bulk material such as chopped wood, chippings, sawdust, or pellets. Modern high-quality wood-fired boilers are well in creeping with the legal limit values, whereas many boilers currently in use do not meet contemporary technical standards. Furnaces for stalky material require a greater technical expenditure. Fuels with a high straw fraction pose the serious problem of emission of fire dust. Straw ash tends to produce slag and must therefore be cooled and reliably removed from the firing zone. (orig./EF) [de

    2008-01-01

    The objective is to assess the prevalence and treatment patterns of generalized anxiety disorder (GAD) in Spain as well as the cost associated to this disorder in different countries. A search in the literature of health and economics databases was conducted. In regards to the 32 references selected, 6 studies had data on the prevalence of GAD and 3 on treatment patterns in Spain and 11 studies on the costs associated to the disease on an international level. The remaining 20 studies were of general interest for methodological or contextual reasons. GAD is a mental disorder with high prevalence. According to some authors, it is probably underdiagnosed. No appropriate long term treatment is available. High health care and social costs are associated to GAD. The frequent presence of comorbidity, different definitions and methodologies used in the studies limits the comparability and synthesis of the results. It also makes it difficult to obtain valid estimations of prevalence and costs.

  8. Opportunities for biomaterials. Economic, environmental and policy aspects along their life cycle

    2010-01-01

    Little was known at the start of these studies regarding the environmental impacts of bulk chemicals production from biomass and whether they could be produced economically. We have therefore analysed the entire life cycle of bio materials: the production of bio-based chemicals, the application of bio-based polymers in packaging and finally the waste treatment of biodegradable materials. Numerous bio-based chemicals offer economic opportunities, the extent of which depends on the prices of the petrochemical and bio-based feed-stocks and can be further improved by technological progress in the future. Almost all bio-based chemicals have lower carbon and energy footprints than their petrochemical counterparts, and savings can be substantially increased in the future. Bio-based materials also offer savings when used for a specific food packaging application, but these savings can become smaller when the comparison is made not per kg of material but considering the functionality and material properties. Biodegradable materials are advantageous in that they are suitable for biological waste treatment options whose carbon and energy footprints are currently at least equally good as incineration, but have the additional benefit of producing a soil conditioner which can improve soil carbon content. Finally, consistent policy measures supporting bio-based and/or biodegradable materials are necessary to ensure this market's success. The progress made in terms of quantifying the benefits, the start of major research and development programmes and the start-up of production facilities have increased the likelihood for many bio-based chemicals and plastics to enter the market. So there are clear opportunities for bio materials, but policy measures are needed to ensure that they can start competing on a larger scale.

  9. Economic aspects of infertility care: a challenge for researchers and clinicians.

    Science.gov (United States)

    2015-10-01

    Infertility care has improved remarkably over the last few decades and has received growing attention from health care providers. Several treatments, including expensive options such as Assisted Reproductive Techniques, are now widely available for routine clinical use. In most cases, adoption of these treatments has occurred without robust cost-effective analyses. IVF for unexplained infertility and ICSI in the absence of semen abnormalities are two examples of this gradual technology creep. More in-depth economic analyses in the field of infertility are undoubtedly warranted. However, performing these analyses is challenging because infertility care poses a number of unique challenges. Studies of cost-effectiveness are open to criticism because there is a lack of consensus about the outcomes of choice and the appropriate perspective. The use of quality adjusted life years (QALYs) to allow comparisons with other clinical conditions is also controversial because the value associated with infertility care cannot be easily captured in QALYs. Moreover, their use triggers the crucial question of whose QALYs merit consideration-an individual's, a couple's or a child's. In conclusion, economic analysis in infertility represents a peculiar but crucial challenge. If management of infertility is to become an integral part of publicly or privately funded health care systems worldwide, better quality data and a shared vision about the costs and benefits of infertility treatments are needed. © The Author 2015.

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

    Full Text Available In order to determine the organizational-economic and accounting aspects of franchising in the context of volatility of the macro-economic situation and the scarcity of entrepreneurs’ own funds, the current status of the franchising market in Ukraine, its economic essence and its role have been determined; the kinds of franchising that are known in world business practices have been provided; the types of distribution contracts that are close to the meaning of franchising have been defined; the legislative basis for franchising in Ukraine has been presented; the binding terms of a commercial concession contract as a legislated analogy of franchising in Ukraine have been determined; the features of reflection of the legality of franchising in accounting of both franchiser and franchisee have been provided. The objective advantages of franchising for both the large enterprises and the start-up entrepreneurs have been determined. On the basis of the legal nature of franchising relations in the accounting accounting, its reflection is close in the meaning to intangible assets. Implementation of franchising potential as a strategic tool for the development of small and medium-sized businesses requires the improvement of its legislative framework in the part of enhancing the responsibility of the parties.

  13. Main aspects of the planned reform of the Act on the Peaceful Uses of Atomic Energy and Protection against its Hazards (Atomic Energy Act)

    Lukes, R.

    1991-01-01

    There is no specific reason for planning a reform of the atomic energy law just now; the main idea is to keep the atomic energy law abreast with the developments made in the regime of protective laws pertaining to the sector of science and technology. A further aspect not to be neglected, however, is the nuclear power phase-out currently under debate, and a decision against the abandonment of nuclear power should be taken as an occasion to think about a nuclear law reform. The judiciary has been contributing to the development of nuclear law in the last years, and the decisions of the Federal Constitutional Court and of the Federal Administrative Court have not only set the corner flags for the future development of the nuclear law, but have given concrete shape by final settlement of cases of divergence of judicial decisions, to the protective intents of the law and to the subject-related purposes. Thus the judiciary has been taking into account the idea prevailing today, namely that the scope of duties of the Federal Government certainly includes the task of protecting the citizens against the hazards of technology in general, and of novel technologies in particular, and the task of avoiding hazards. So the main line of orientation to be pursued is to draw level with protective regulations established in other fields of law, and to make the Atomic Energy Act a modern instrument of protection by the law.

  14. Animal Welfare and Economic Aspects of Using Nurse Sows in Swedish Pig Production

    Directory of Open Access Journals (Sweden)

    Karin Alvåsen

    2017-12-01

    Full Text Available The number of born piglets per litter has increased in Swedish pig industry, and farmers are struggling to improve piglet survival. A common practice is to make litters more equally sized by moving piglets from large litters to smaller to make sure that all piglets get an own teat to suckle. Litter equalization is not always enough, as many sows have large litters and/or damaged teats, which results in an insufficient number of available teats. One way to solve this problem is to use nurse sows. A nurse sow raises, and weans, her own piglets before receiving a foster litter. The objectives of this study were to address how the use of nurse sows affects the welfare of sows and piglets and to explore how it impacts the contribution margin of pig production in Sweden. A literature search was made to investigate welfare aspects on sows and piglets. As there were few published studies on nurse sows, an expert group meeting was organized. In order to explore the impact on the contribution margin of pig production, a partial budgeting approach with stochastic elements was used for a fictive pig farm. Standard templates for calculating costs and benefits were supplemented with figures from existing literature and the gathered expert opinions. In Sweden, the minimum suckling period is 28 days while published studies involving nurse sows, all from outside of Sweden, weaned the piglets at 21 days. A Swedish nurse sow will thus get longer lactation period which might increase the risk of poor body condition, damaged teats, and shoulder ulcers. This indicates a reduced welfare of the sow and may lead to impaired fertility and increased culling risk. On the other hand, the piglet mortality could be reduced with the use of nurse sows, but the separation and mixing of piglets could be stressful. The partial budgeting suggested that the nurse sow system is slightly more profitable (+6,838 Swedish krona per farrowing group during one dry and one lactation

    Capture and storage of CO2 (CCS) has been studied as an option in the portfolio of climate change mitigation strategies for about 20 years. Although the technical maturity of CCS is generally less than other mitigation options, such as renewable energy or energy efficiency, many of the CCS components are generally regarded as mature enough for deployment. CCS, however, has a number of other aspects that may inhibit its deployment. The aim of the ACCSEPT project is to identify the main gaps in knowledge in the non-technical aspects of CCS, to research them, and to propose recommendations to address them. Although in the recent past several large and influential reports have been published in the field of CCS, many of them have focussed on the technical aspects of CCS. The IPCC Special Report on CCS did not have the mandate to address policy aspects and could only touch upon public perception issues. An IEA report focussed on the costs and economic aspects of CCS and touched upon regulatory and risk issues, but was at the time of publication unable to dive deep into it. This report provides a critical literature review for the non-technical aspects of CCS in the following categories: (a) Legal issues: National and international legislation relevant to CCS. Examples include national drinking water and mining laws, and the London Convention (Chapter 2). (b) Regulatory issues: National and international policies in the field of energy or climate change that can act as support mechanisms for CCS (Chapter 3). (c) Costs and economics: Addresses the question whether the current costs assumed for CCS are interpreted correctly, and reviews the assumptions made in economic models informing the policymaking process (Chapter 4). (d) Social and acceptability issues: A review of all studies currently done that focus on public perception of CCS. Methods used are questionnaires with lay public, focal group discussions, and expert polls (Chapter 5). (e) Crosscutting issues: CCS as a

  16. THE EXTENT TO WHICH DEVELOPING COUNTRIES ARE INVOLVED IN INTERNATIONAL FINANCIALFLOWS AND THE MAIN EFFECTS ON ECONOMIC DEVELOPMENT

    Full Text Available Foreign direct investments are an important factor for economic growth and development. Throughout time, the source and destination of foreign direct investments have undergone significant changes and thus, starting with the 2000’s there has been an increasingly more global involvement of developing countries in the global flow of foreign direct investments. These countries are currently accountable for more than a quarter of the global outward FDI flows and for almost half of the total global inward FDI flows. In light of the changes that have occurred worldwide after the global financial crisis, the economic policy measures tend to vary from encouraging FDI’s to limiting them. If some countries see FDIs as an important factor for economic growth and global expansion, others only perceive the strong competition from foreign companies, which can lead to a loss of control over domestic capital. At the same time, as the North-South disparity faded, there is evidence that developing countries have become more involved in international financial flows during the past few years. In order to highlight this issue, we have analysed the existing data for a period that has seen a strong financial integration of emerging markets and a decreased volatility of financial flows in advanced industrialised countries (1970-2013. We will particularly approach the relationship between economic growth and international capital flows, with specific reference to foreign direct investment flows (FDI.

    Work is well advanced on design and construction of the next major increment of U.S. uranium enrichment capacity. The plant will use the gaseous diffusion process to provide the required capacity and reliability at a competitive enrichment services cost. Gaseous diffusion technology is the base against which other processes are compared in order to assess their commercial viability. While it has generally been described as a mature technology with limited future development potential, work on design of the new U.S. plant has resulted in major improvement in plant design with corresponding decreases in plant capacity and operating costs. The paper describes major technological advances incorporated into the new plant design and their impact on enrichment costs. These include the effects of: - advanced barrier technology; - tandem compressor drive systems; - optimization of number of equipment sizes; - single level plant design; - development of rapid power level change capability; - electrical system simplification; - plant arrangement and layout. Resulting capital costs and projected enrichment costs are summarized. Enrichment costs are placed in the context of total nuclear fuel cycle costs. Trade-offs between uranium feed material quantities and enrichment plant tails assays are described, and optimization of this aspect of the nuclear fuel cycle is discussed. The effect on enrichment plant characteristics is described. Flexibility and capability of the new U.S. enrichment plant to meet these changing optimization conditions are described

    In the context of the wind power use increase in the european union, the average wind turbines power increases also. These turbines are more adapted to little wind conditions. The offshore wind power is certainly the more adapted to the problem of implementation sites, meanwhile the offshore project costs are more expensive. More competitive costs are a challenge for the offshore wind channel. The author presents also the main technological evolutions, the french wind power industry and the future of this energy in France. (A.L.B.)

    Full Text Available Between 2009 and 2013, research was conducted in the commune offices for the Podlaskie voivodeship which have large areas of protected Natura 2000 sites. The research is repeated every few years and widened to include new communes. The aim of the research was to determine the influence of the protected areas on the economic conditions of the communes. It is widely assumed that protected areas generate income for communes, however the communes claim that they incur large additional costs. The surveyed communes were critical of obligatory legal requirements in relation to the protected areas. It was argued that there are problems with obtaining natural resources and with the establishment of new summer resorts, residential and farm buildings and infrastructure; as well as the use and management of the site. The communes’ benefits incidental to the ownership of the protected area are not clear. As part of the benefits, the protected areas offer an opportunity for tourism development. According to the communes, protected areas generate losses in which the estimated losses are several times higher than the potential income. Studies indicate that the conservation cost factor should be considered in terms of financing the communes from the state budget.

    In recent years, major maritime nations such as Japan, Russia and Norway have been investigating the use of the Northern Sea Route (NSR) as a sea route between the Far East and Europe, linking the eastern and western parts of the Eurasian continent. In this study, as part of the examination of suitable merchant ships for the NSR, we make an economic comparison between diesel container ships taking the Suez Canal route and NSR nuclear-powered icebreaking container ship carrying the Marine Reactor X (MRX), which is currently being developed at the Japan Atomic Energy Research Institute. Compared to diesel container ships going via the Suez Canal, the first-year transportation cost of NSR nuclear-powered container ship after commissioning is 30-70% higher and the required freight rate (RFR) is 8-40% higher. If the nuclear reactor in nuclear-powered container ship, which is the reason for higher cost, were replaced by the cassette-type MRX, the reusability of the MRX would reduce this cost difference between nuclear-powered and diesel ships. The study also shows that in terms of the total cost including sales opportunity costs, NSR nuclear-powered container ship can compete sufficiently with diesel container ships on the Suez Canal route.

    Full Text Available The article is aimed at studying the theoretical foundations of origin and use of the concept of «quality» in the economic environment. The evolution of the concept of «quality» was researched, as a result it was found that the term «quality» has both objective (measurable and computational and subjective (measurable only individually characteristics. Systematization in relation to the concept of «quality» is carried out both at the macro level – through development of the whole of normative-legal acts, and at the micro level – when the enterprises choose their own management strategies. The assessment of the legal interpretation of the category of «quality» in the article allowed to assert that the key is the Law of Ukraine «On protection of consumer rights», but in their activity domestic enterprises in parallel apply the standards of DSTU ISO of the Series 9000, the use of which is a kind of evidence of the reliability of a business partner. Evidence of the quality of each individual product or service is compliance with certain industry standards.

    Since 2005, great progress has been made in health care provision to patients with terminal renal failure in Bolivia. Access to dialysis and transplantation is regulated by the Ministry of Health, based on clinical criteria, applied equitably, without favoritism or discrimination based on race, sex, economic means, or political power. Until December 2013, there were no restrictions in dialysis and transplantation in Health Insurance institutions, but they covered only 30% of the population. Now the remaining 70% has access to free dialysis funded by the communities where patients live, with funds coming from the government and taxes on oil products. More than 2,231 people are getting dialysis, reaching a population growth of >60% annually. The number of hemodialysis units has increased by >200% (60 units), making access easier for end-stage renal failure patients. Treatment protocols have been drawn up to guarantee the best quality of life for the patients. The Law on Donation and Transplantation was enacted in 1996, and Supplementary Regulations were enacted in 1997 with various amendments over the past 5 years. A National Transplant Coordination Board, working under the National Renal Health Program, supervises and regulates transplants and promotes deceased-donor transplantation in an attempt to cover the demand for donors. Rules have been drawn up for accreditation of transplant centers and teams to guarantee the best possible conditions and maximum guaranties. Since January 2014, the National Renal Health Program has been providing free kidney transplants from living donors. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objective. A Socio-economic-political-cultural (SEPC) study was undertaken under the Roll Back Malaria (RBM) initiative to understand the process of programme implementation and how far in the changing malaria context, the broader environment has been understood and programme components have undergone changes. Material and Methods. Two studies were carried out; first in four villages under the primary health unit (PHU) Banavaralu in Tiptur Taluka in September 2002 and the second one in April 2003 in four villages in Chitradurga district, namely, Kappagere, Kellodu in Hosadurga Taluka, and Vani Vilas Puram and Kathrikenhally in Hiriyur Taluka. Focus group discussion and key interviews were adopted to collect the qualitative data. Results. Gender discrimination and lack of empowerment of women came out strongly in social analysis. In the rural elected bodies called Panchayats, the concept of health committees was not known. Health committees as one of the important statutory committees under every Panchayat were nonexistent in reality in these villages. Financial difficulties at Grama Panchayat level and also meager budget allocation for health have led to indifferent attitude of Panchayat members towards health. It was observed that there were generally no specific cultural practices in relation to malaria cure. Cultural and traditional practices in malaria-related issues were not predominant in the community except for some sporadic instances. Conclusion and Recommendation. SEPC study is an important indicator in malaria control programme. It is ultimately the community that takes the major decision directly or indirectly and the health authority must guide them in right direction.

    Full Text Available The development of world integration processes, related to the movement of labor, determines objectively the need for reforming the Russian system of education. In this connection, ensuring the quality of education, that meets the needs of the modernity, is a major strategic challenge of state education policy. That is why universities pay special attention to the formation of faculty members, development of international cooperation of universities and joint participation in the implementation of innovative educational programs, including by involvement foreign lecturers to work in Russian universities and also foreign students. Implementation of innovative education programs in the Russian Federation has contributed significantly to the development of international cooperation of universities and laid the foundation for long-term collaboration with foreign counterparts in educational and research areas. Internationalization of educational systems in developed countries has become an objective need. As a result, cultural contacts have significantly increased between countries. The information exchange started regarding accomplishments in the field of education. To determine the readiness of a scholar for development of an international research project and for the activity in the international scientific consortium is an extremely important issue about the economic feasibility of participation of each candidate. This paper argues government regulations regarding labor of foreign lecturers and payment of their services by a university.

    Full Text Available In the area of modern economy and environmental protection there are no significant changes: the old problems are not solved, and the existing ones are deepening. Humanity is still struggling with three existential problems: lack of food, lack of drinking water and insufficiently energized energy. They are also associated with the dangers of further degradation of the environment, the general fear and fear of terrorism and wars, the emergence of diseases for which modern medicine simply has no solution and which threatens to overcome the challenge of pandemic. Energy is still a mood of economic development, with at the same time a disastrous effect on the environment, when traditional sources of fossil resources are used as sources of energy. The paper explores the phenomenon of the impact of energy on the sustainable development of the economy, with a key focus on environmental protection, as well as the possibilities for adaptation to mitigate the consequences of this global phenomenon. In this regard, special attention has been devoted to researching the role and significance of energy from renewable sources as a possible response to current or expected climate stimuli or their consequences in natural and humanism systems. Particular emphasis is placed on the principle of adaptation, which includes mitigation of damages or the exploitation of effective opportunities; understanding how climate can change, what can be impacts, and capacity building and action on these impacts

    Full Text Available The paper aims to study the perception of the political agents of the Congress through the analysis of their votes on the context of the acceptance of Venezuela into MERCOSUR, relating it to the potential gains coming from its admission. The relevance of the topic is justified by the importance that the bloc would acquire accepting a new member, considering the expansion of the internal consumer market and the increase of oil reserves of the bloc. Therefore, the intention is to clarify the political situation favorable to the integration and, taking the Brazilian perception in consideration, establish the relationship between economic gains that would come from the acceptance of Venezuela as a state member and the political discourse regarding this subject in the National Congress. Through the votes of deputies and senators we mapped the variables that act as important factors in the decision-making process of lawmakers. It was found that the party influence, though strong, suffers marginal effects of variables such as the influence of regional and local interests when it comes to voting on foreign policy.

    To achieve optimum water conservation and improved water use efficiency, a water conservation enabling environment is needed that includes: 1. Education and training, improvement of management systems and public incentives: these measures allow increase from 20 to 30 % water resources .2. irrigation management transfer to users, management of supply infrastructure and an optimised resource policy to arrive at 60 to 80 % of the potential; 3. further research of the public and the private sector to utilise fully the whole available potential. Pakistan's water-resources have been diminishing at an alarming rate, due to further increase of population, per capita water availability in Pakistan goes down below 1,000 m/sup 3/, that means Pakistan is nearing conditions of chronic water-stress. The quality of water is also deteriorating with time. To improve the situation, potential of socio economic factors can be mobilized like population stabilization, community involvement, fair water distribution, application of water harvesting and water conservation at the community level, application of non- structural solutions, for example pricing of water, to develop water management institutions, public education and awareness are essential. Selection of appropriate low cost technology is a pre-requisite for widespread project implementation, planner should consider both traditional and modern technologies. The price of water determines largely the investments justified to avoid water losses. (author)

    Full Text Available In the article with the help of two-sector model of the economic system, the interaction of national and regional economy is investigated. This interaction is observed from the position of development of material structure and institutions. As the key structural parameter of an economy, the proportion between sector of excess resources and sector of scarce resources is taken. The situation when sector of excess resources prevails over sector of scarce resources forms structural conditions for the creation of the market institutions. If a sector of excess resources is smaller than a sector of scarce resources, the conditions for the emergence of institutions of government regulation are formed. Two cases are analyzed: the first one concerns the situation of a simple national economy consisting of 2 provisory regions. The second is the case of the national economy consisting of many regions. The authors show that material structure of a total combination of regions defines institutions of the market or state regulation for the national economy as a whole. The institutions formed at the level of the national economy, can support or resist the development of structure of the region. The conditions are observed under which united institutions of the national economy contradict a development of structure of the individual region.

    Australia is a significant livestock producer and a major exporter of livestock, livestock products and livestock genetic material. An outbreak of foot and mouth disease (FMD) would have severe economic consequences on the economy. A recent study found that in an outbreak lasting six months, real gross domestic product in Australia would fall by an estimated 0.6% (AUS$3.5 billion), employment by 0.8%, and a depreciation of 3% would be recorded in the exchange rate in the first year. Much of this impact would be due to the loss of export markets. Given the significant consequences of an outbreak of FMD, Australia invests considerable resources in prevention and planning. These measures can be viewed at three levels, namely: pre-border, border and post-border. Australia recently further enhanced quarantine at the border to minimise the risk of entry of FMD. However, no matter how much is invested, there is no guarantee that FMD will not enter the country. Accordingly, it is important to ensure that comprehensive contingency plans are also in place. Recent outbreaks in previously free countries have shown that a large outbreak of FMD poses major problems for the animal health services of a country and a combined government and industry response is required.

    Some of the difficulties which confront New Zealand in devising an appropriate energy policy are evaluated. Certain measures, involving a variety of instruments, intended to further a general aim or aims, embodied in more or less precisely defined objectives, are discussed. Social, economic, political, and technical desiderata and constraints will all be involved in varying degree, and definitive conclusions are unlikely. A further problem is that ends and means may be interdependent. The only certain thing about the future is that it cannot be forecast with any accuracy. This is as true of energy matters as of other things, despite the confidence with which some energy forecasts are made. Confronted with such uncertainty, it is sensible to leave open as many options as possible for as long as possible. More arguably, the unavoidable uncertainty about the future weighs against currently avoidable sacrifices in the interests of generations to come. It is simply not known whether the twenty-first century will judge them to have been worthwhile or not.

  11. ENVIRONMENTAL AND ECONOMIC ASPECTS OF ANTICORROSION PROTECTION BY HOT-DIP GALVANIZED METHOD REBARS IN CONCRETE

    2015-05-01

    Full Text Available The implementation of the sustainable development concept is nowadays a key issue in almost all human activities. For the constructions domain an European strategy has already been elaborated. Among its goals are also the use of long lasting materials and the reduction of repair costs. This paper presents an interdisciplinary study concerning the efficiency of the use of hot-dip galvanized rebar for concrete structures. Experimental results about corrosion kinetics of coated and usual steel reinforcement embedded in concrete, subjected to chlorine ions attack, are analyzed. Electrochemical methods as chronoamperometry and linear polarization have been used. Corrosion potential values recorded for galvanized steel embedded in concrete indicate an uncertain corrosion activation process up to a rate of 2.5 % calcium chloride relative to concrete. For rates of 5% CaCl2 and more the corrosion process is activated. For unprotected steel bars embedded in concrete the corrosion activation process started at all calcium chloride studied rates and higher corrosion potential values has been registered than for the hot-dip galvanized ones, at the same rates. Economical assessments have been done using entire lifetime cost analysis of the reinforced concrete structures. Despite that the hotdip galvanization is a rather expansive procedure, when taking into account the whole expected life span, the use of zinc coating proves to be efficient both from structural and financial approaches.

  12. Some aspects of natural gas and economic development - a short note

    Just because gas is labelled the fuel of the future does not ensure that it will become exactly that; but faith is important. If the world's energy establishments really want to expand their use of natural gas, all the objective conditions exist to make this expansion possible: large and increasing gas supplies; impressive changes in gas-burning technologies; a widespread acceptance of gas by both the general public and environmentalists; and so on. The considerable increase in the supply of gas is probably regarded as bad news by many exporters of gas, but I am not so sure that this will prove to be the case. Instead, a situation may be foreseen where the widely advertized rising supply will tend to encourage demand, since many actual and potential gas users will be inclined to interpret rapidly increasing gas reserves as the forerunner of an extended buyers' market. Two other factors working in favour of natural gas are the growing belief that the remaining reserves of oil are considerably more limited than previously believed and the increase in the value of natural gas due to technological advances being made in gas-burning equipment. The pattern of economic growth and development in Sweden which does not have natural gas and the key role of the electricity sector, is a pointer to countries which do possess gas that they should pay particular attention to its value in electricity generation.

  16. Restructuring upstream bioprocessing: technological and economical aspects for production of a generic microbial feedstock from wheat.

    2004-03-05

    Restructuring and optimization of the conventional fermentation industry for fuel and chemical production is necessary to replace petrochemical production routes. Guided by this concept, a novel biorefinery process has been developed as an alternative to conventional upstream processing routes, leading to the production of a generic fermentation feedstock from wheat. The robustness of Aspergillus awamori as enzyme producer is exploited in a continuous fungal fermentation on whole wheat flour. Vital gluten is extracted as an added-value byproduct by the conventional Martin process from a fraction of the overall wheat used. Enzymatic hydrolysis of gluten-free flour by the enzyme complex produced by A. awamori during fermentation produces a liquid stream rich in glucose (320 g/L). Autolysis of fungal cells produces a micronutrient-rich solution similar to yeast extract (1.6 g/L nitrogen, 0.5 g/L phosphorus). The case-specific combination of these two liquid streams can provide a nutrient-complete fermentation medium for a spectrum of microbial bioconversions for the production of such chemicals as organic acids, amino acids, bioethanol, glycerol, solvents, and microbial biodegradable plastics. Preliminary economic analysis has shown that the operating cost required to produce the feedstock is dependent on the plant capacity, cereal market price, presence and market value of added-value byproducts, labor costs, and mode of processing (batch or continuous). Integration of this process in an existing fermentation plant could lead to the production of a generic feedstock at an operating cost lower than the market price of glucose syrup (90% to 99% glucose) in the EU, provided that the plant capacity exceeds 410 m(3)/day. Further process improvements are also suggested. Copyright 2004 Wiley Periodicals, Inc.

    Full Text Available Below replacement fertility was the outcome of changes in the education and socio-professional structure of women, as well as modifications in values and life aspirations. On the other hand, economic strengthening of women and encourage-ment of jobs which require greater dedication and more of their time are important aspects of achieving gender equality. These two circumstances gave rise to contemplations on the connection between economic activities of female population and the level of births in postindustrial societies. The aim of this article is to point out to the positive influence of female employment on the fertility level, as a capacity for encouraging births in Serbia. When observing the most developed European countries, it can be noticed that greater birth rates are noted in those countries in which there are greater economic activity and employment rates of female population. Furthermore, a series of researches and comparative analyses confirm the positive relation between female employment and fertility. The differences regarding of birth rates among European welfare states are seen as a result of the possibilities of female employment, reconciliation between work and parenthood and the division of gender roles within the family. The influence of economic activity on fertility levels is determined by an institutional framework of family support and gender equality (Engelhardt and Prskawetz, 2004, Neyer, 2006; Andersson and Scott, 2007; Rovny, A.E. 2011; Seeleib-Kaise and Toivonen, 2011. During the first decade of the 21st century, the birth rates in Serbia were by about 30% lower than in the countries which had the highest fertility within European frameworks. The traditional labor division in the household and parenthood produces conflicts between families and employment, recognized in the practices of everyday life (Blagojević, 1997; Blagojević-Hjuson, 2013 and standpoints on the relation between parenthood and employment

    Marketing-driven innovation in the field of pediatric nutrition, in particular in the infant formula segment is not sustainable. New benefits of products must be scientifically proven and safety and efficacy of new formulae established in clinical trials. The scientific innovation process of three infant formulae is described. Improvement in protein quality allowed to reduce the protein concentration in whey-based infant formula. Weight gain and BMI of infants fed those formulae corresponds to breastfed infants and is lower than in infants fed traditional formulae with higher protein concentration. A meta-analysis indicates associations between rapid weight gain in infancy and obesity later in life. If infants cannot be exclusively breastfed until 4-6 months of age, feeding low-protein formulae may contribute to positive long-term health outcome with potentially important health economic effects. A partially hydrolyzed whey based formula for prevention of allergic symptoms in children with hereditary risk for allergic diseases was developed more than 25 years ago. The most recent meta-analysis which included 15 randomized clinical trials indicates that the risk of all allergic diseases and atopic dermatitis/eczema is significantly reduced in infants at risk when the partially hydrolyzed formula is fed. The partially hydrolyzed formula had the same protective effect as casein-based high-degree extensively hydrolyzed formula. Because of substantial price differences between the two formulae, feeding the partially hydrolyzed whey formula is cost saving. Hypoallergenic claims can be made in many countries, and international nutrition committees have positively commented the preventive effect of those formulae. Acidified formulae have been widely used during the last decade in replacement feeding programs for infants whose mothers are HIV positive. The formula was innovated by improving whey protein quality and lowering protein concentration. The bacteriostatic

    Full Text Available Objective: to estimate the cost of treatment in patients with complicated osteoporosis (OP in the first year after fracture under the conditions of the Moscow municipal healthcare system.Patients and methods. The investigation enrolled 196 women (mean age, 65.8±9.1 years who had sustained fractures at five major osteoporotic sites (proximal hip (PH, distal forearm (DF, surgical humeral neck, vertebral column, and medial and/or lateral ankle. A unified questionnaire that included data on inpatient and outpatient treatment, patients' personal costs, and social benefits, as well as tariffs on services of the Moscow City Fund of Obligatory Health Insurance was used to estimate the cost of treatment for complicated OP during one year after fracture.Results. The direct cost of treatment for PH fracture amounted to 101,243 rubles and was significantly higher (p < 0.01 than that for fractures at other sites: DF (22,080 rubles; humeral neck (39,855 rubles, vertebral column (51,167 rubles, and ankle (43,345 rubles. The average cost of treatment in terms of indirect costs of treatment for complicated OP during a year was as high as 61,151 rubles. In the overall cost structure for the disease, hospital costs accounted for 44%; social benefits were 12% and the cost of antiosteoporotic drugs was only 7%, which was associated with the fact that the latter were rarely prescribed by primary healthcare physicians.Conclusion. Costs of treatment in patients with complicated OP in Moscow were estimated in relation to the site of low-energy fracture. The disease was shown to cause considerable economic losses regardless of the site of osteoporotic fracture; however, the cost of antiosteoporotic drugs has an insignificant share in the overall cost structure for treatment. At the same time, secondary prevention of OP requires that combination antiosteoporotic therapy should be performed in all patients who have sustained low-energy fracture.

    Full Text Available The Kolubara district covers the north western part of Serbia. A total of 62,330 ha or 25.3% of the Kolubara district is forest covered. Out of the total forest area, app. 18.7% are state owned, and 81.3% are private forests. The average annual volume of wood that is exported from the forests of the Kolubara district is 60,000 m³ of hardwood and 670 m³ of softwood. In the total volume of harvested timber, beech as a species participates on average with 60%. The aim of the research is to determine the amount of the purchase, marketing/ placement and price of wood and non-wood forest products (NWFPs in the municipalities of Valjevo, Ub and Lajkovac. The purpose of this research is to investigate and determine the possibilities for the development of forestry, as well as small and medium-sized enterprises, which are directed towards the use of wood and NWFPs in the are of Kolubara. The subjects of research are: companies that do business in this area, the quantities that are purchased and marketed, the prices at which the products are implemented, as well as strategic documents of local self-government, which are important for economic analysis. The research was conducted in the territory of the Kolubara District, and covers 6 companies. Decreasing trends in the placement of technical wood with an average growth rate of -20% and stacked wood with an average growth rate of -12% of private forests as well as the declining trend in placements of beech logs for cutting first class with an average growth rate of -10% indicate that the wood stocks in forests is each year less and that they must be taken appropriate steps to correct the situation. The inadequate utilization of roe deer, as a resource, point percentages of realized shooting plans and projected revenues. However, it is present growth trends of shooting, with an average growth rate of 8% and placement of roe deer meat, with an average growth rate of 9.9%.

    Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have been efficiently used for enhancing the productivity of natural food of carps and related species. Besides, several organic wastes/byproducts such as plant products, wastes from animal husbandry, and industrial by-products have been used as carp feed ingredients to lower the cost of supplementary feeding. However, to ensure the continued expansion of fish ponds and the pollution control, there must be a market for the fish (carps) produced in these ponds. The carps have, however, a low market value due to the presence of intra-muscular bones, which reduces their consumer acceptability. Thus, a need was felt to develop some boneless convenience products for enhancing the consumer acceptability of the carps. Efforts were made to prepare three value-added fish products, namely fish patty, fish finger and fish salad from carp flesh and were compared with a reference product ('fish pakoura'). Sensory evaluation of these products gave highly encouraging results. The methods of preparation of these products were transferred to some progressive farmers of the region who prepared and sold these products at very attractive prices. Carp processing has a great potential for the establishment of a fish ancillary industry and thus for boosting the production of these species. In Punjab alone, there is a potential of consuming 32,448 metric tonnes per annum of such value-added products (which would require 54,080 metric tonnes of raw fish). The development of value-added products has a significant role in raising the socio-economic status of the people associated with carp culture. The

    Full Text Available The paper presents the epidemiology and socio-economic aspects of the three most common rheumatic diseases: rheumatoid arthritis (RA, systemic lupus erythematosus (SLE and scleroderma. The incidence of rheumatic diseases in a population is estimated at 4–5%. Prevalence rate for RA in Poland is 0.45% of the adult population and is similar to the rate reported in the EU (0.49%. It is estimated that the average incidence of SLE is 40–55 per 100 thousand and that the annual incidence of systemic sclerosis is 19–35 cases per million (depending on the country. Nearly 18% of all hospital admissions in Poland are associated with rheumatic diseases. The introduction of new classification criteria for rheumatoid arthritis, allowing classification of the early forms of the disease and their use in clinical practice will probably change the assessment of incidence of this disease in the population.

    Full Text Available Abstract: Studies on the functioning of loan management models in banking institutions are of special significance for the ascertainment of efficient credit disbursement modalities and policies, with the aim of ensuring strategic and financial development. In their monetary programs, banks among other make assumptions on the increase of the demand for cash from loans for their respective economies and businesses. Supporting the economy through loans represents one of the main tasks of any banking system, and this is especially applicable in countries with specifics similar to our country. During the last half of the previous decade, the structure of deposits in the banking system underwent severe changes, which were generally in function of the country\\'s development, but also assisted in the development of the banking system itself. The overall tendency of the deposits in the banking system was positive, and charts and series matrixes show their ever growing tendencies. However, the vulnerability and problems of the first decade after the establishment of any banking system are reflected in crises and problems noted in the structure and level of deposits of such banking systems, which in the case of Kosovo was further reflected in external and internal factors affecting loans and their overall default.

    A methodology has been developed to carry out an integrated oil spill vulnerability index, V, for coastal environments. This index takes into account the main physical, biological and socio-economical characteristics by means of three intermediate indexes. Three different integration methods (worst-case, average and survey-based) along with ESI-based vulnerability scores, V(ESI), proposed for the Cantabrian coast during the Prestige oil spill, have been analyzed and compared in terms of agreement between the classifications obtained with each one for this coastal area. Results of this study indicate that the use of the worst-case index, V(R), leads to a conservative ranking, with a very poor discrimination which is not helpful in coastal oil spill risk management. Due to the homogeneity of this coastal stretch, the rest of the methods, V(I), V(M) and V(ESI), provide similar classifications. However, V(M) and V(I) give more flexibility allowing three indexes for each coastal segment and including socio-economic aspects. Finally, the V(I) procedure is proposed here as the more advisable as using this index promotes the public participation that is a key element in the implementation of Integrated Coastal Zone Management (IZCM).

    This summarizes population trends in the U.S.S.R. since the early 19 00's. On August 9, 1973, the population topped 250 million, almost precisely double that of Russia at the time of the 1st general census in 1897. Since 1922 it had increased by more than 84%. Russia has suffered more population loss in wars than any other country in modern times. The First World War, the Civil War, and the Second World War took a toll of more than 30 million, more than 20 million during the Second World War alone. The extent of these loses can be judged from the following: between 1897 and 1913 the population of Russia increased at the rate of 1.55% per annum or 34.6 million; if this had continued the population would have been at least 182.8 million by the end of 1922. As it was, the population was 136.1 million by 1922 and the hypothetical 182.8 million was not reached until 1952. More than 4/5 of today's population have been born since the October Revolution. Only 43 million were born before the revolution and only 7.5 were born in the last century. The economic base has grown much more rapidly than the population. For the period 1940-1972 the population increased 1.27 times, national income 9.51 times, fixed assets, 8.76 times, industrial production, 13.65 times, agricultural output, 2.14 times, and capital investment 14.52 times. The birthrate has been falling since World War 1 but total population growth has increased steadily. Birthrates have declined from 45.5/1000 in 1913 to 17.8/1000 in 1972 and a slight upturn is seen. It is expected that the birthrate will continue to increase slightly, then stabilize. Much of the population increase has come from significantly reduced mortality rates. 1st and 2nd children now account for 71% of all births. Family allowances, child care, free health care, and other social benefits encourage births while high employment levels for women, a shortage of men in the marriageable age ranges, and late marriages tend to depress the birthrate

    Full Text Available The article is devoted to topical problems of small business development in the world production practice. The main tendencies of development of small business in modern conditions are noted, in particular, the directions of development of innovation-oriented small business are considered on the example of the Republic of Kazakhstan. Domestic and foreign experience has proved that supporting small businesses from the state is an integral part of the market economy. Small business, gaining a solid position in the market, needs development and state regulation. In foreign countries, small and medium-sized businesses represent an important sphere of employment for the population, promotes the development of the innovative potential of the economy, and the search for and introduction of innovations that are a factor in obtaining competitive advantages for enterprises, industries, regions. To realize its potential, state support should be carried out simultaneously in several directions, which will enable it to cover all small business sectors: the sphere of real production through the subcontracting mechanism, the sphere of circulation through the franchising mechanism, the sphere of applied science through the mechanism of venture contracts. It is also necessary to have banks specially created to participate in small business support programs and the activities of "business incubators". For a significant rise in the national economy, it is necessary to promote the maximum increase in the number of small innovative enterprises in the production sector, to stimulate the development of interrelations between small, medium and large industrial business, to creatively use the relevant foreign experience. All this should become an integral part of the overall policy in the field of restructuring the domestic economy, since business as a whole, regardless of its scale, is a single and interrelated process.

    Fossil fuels combustion in the energy sector is a major contribution to the generation of greenhouse gases emission (GHG) -- mainly carbon dioxide. Emissions reduction represents an important means to protect the environment and to improve the health status of the population -- the major requirement in the context of a sustainble development strategy -- knowing the association of the greenhouse effect with climate change. Fossil fuels are limited and expensive resources. According to the Romanian National Agency for Mineral Resources (2009), under the current extraction level the national oil and gas resources are industrial exploitable for 15 years, while coal would be available for about 30 years. At present, the alternative of renewable energy -- solar, wind, geothermal, hydro, and biomass -- is becoming more and more attractive at the global scale. The use of renewable energy offers a clean alternative for energy production, which allows considerable reduction in emissions of greenhouse gases, contributing to climate change mitigation efforts, and also savings of fossil fuels limited resources. Wind energy represents an increasingly more attractive alternative in Romania. Regulations concern not only investment and operation of installations, but also energy recovery and environmental protection. Even though the use of the entire national wind energy potential could determine a significant GHG emissions reduction, the technology, infrastructure and environmental restrictions limits wind energy valorization. Wind farms development, sustained by landscape, wind speed distribution and investors financial promotion, competes with the prudence imposed by the potential environmental impact (biodiversity, microclimate, etc), and the lack of historical data and information structuring. Adequate organization and dissemination of relevant information might be valuable for investors and sustainable development strategies. To estimate the GHG emissions reduction in Romania

    Full Text Available The purpose of this study is to analyze the socio-economic and agro-ecological aspects of chili production in three selected communities of three districts —Magelang, Brebes, and Rembang—that represent distinct agro-ecosystems of chili cultivation within Central Java province. This is to answer a problem statement that chili farming still faces crop protection aspects as limiting factors in chili production. This study uses quantitative descriptive methods. Data were compiled from a survey of 160 chili farmers in 2010-2011. The results show that yield loss due to pests and diseases was considerable, and some of these problems were becoming difficult to control. The three top pests were thrips, mites, and whitefly; and the top three diseases were Anthracnose, Gemini-viruses, and Phytophthora. During the wet season, risk of anthracnose was very high; in the dry season, risk of yield lost to Gemini-viruses and Phytophthora was high. The potential losses could reach 100%. There is a crucial need to solve the problems by enhancing farmers’ knowledge and involving research institutions focusing on crop protection strategy.

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

    The quality of life and pharmaco-economic aspects of obsessive-compulsive disorder (OCD) have received relatively little research attention to date. We aimed to gather preliminary data on these in a South African patient sample. A survey of members of the Obsessive-Compulsive Disorder Association of South Africa was undertaken by means of a detailed self-report questionnaire. Results of the survey suggest that OCD causes significant morbidity, leading to clear distress and Interference with academic, occupational, social and family function. Unfortunately, correct diagnosis and appropriate treatment have been delayed in many patients, and the financial costs of such incorrect management are likely to be considerable. Much further work needs to be done by the medical profession and by interested consumers to raise awareness about OCD and to provide information about its management. In South Africa, it is particularly Important to undertake such psycho-education at a primary health care level and to impact on patients of low socio-economic status.

    Highlights: • Performance cost model assesses the feasibility and profitability of PV systems. • Multi-country and multi-parameter analysis of PV systems in the European Union area. • The impact of key technical, environmental, economic and financial data is assessed. • Germany, Italy and Spain present the most effective PV sector support strategies. • The rated power and energy self-consumption ratio affect PV plant profitability. - Abstract: In the last decades, the attention to solar energy as a renewable and nonpolluting energy source increased a lot through scientists, private and public institutions. Several efforts are made to increase the diffusion of such a source and to create the conditions making it competitive for the energy market. Particularly, for the photovoltaic (PV) sector, the module efficiency increase, manufacturing cost reduction and a strong public support, through favorable incentive schemes, generates a significant rise in the installed power, exceeding 40 GWp in 2010. Although the global trend of the PV sector is positive, differences among countries arise out of local peculiarities and evolutions in the national support policies. This paper investigates such issues focusing on the feasibility analysis of PV solar systems for eight relevant countries in the European Union area, i.e. France, Germany, Greece, Italy, Spain, The Netherlands, Turkey and United Kingdom. A multi-country and multi-parameter comparative analysis, based on the net present value and payback capital budget indices, allows to highlight the conditions most affecting the economic feasibility of PV systems. The national support strategies, along with the most relevant technical, environmental, economic and financial parameters, are the key features included and compared in the analysis. The major results deal with the conditions which make PV systems potentially profitable for each country and installation feature. The national support strategies to the PV

    Full Text Available Subject: technical and economic processes and aspects of handling wastes and secondary material resources; stages of transition of anthropogenic object of environment to wastes and secondary material resources; technical possibility and economic feasibility of using secondary material resources as a secondary raw material for making products, providing energy, works, services. The problem of economy and rational use of material and power resources is relevant and significant within the limits of maintenance of a strategic course of Russia on innovative sustainable development. In this article, issues of actualization and harmonization of the regulatory and legal base in the field of management of wastes and secondary material resources are considered from the viewpoint of maintenance of minimization of waste formation and maximum use of secondary material resources in an industrial-economic cycle, provision of economic incentives for innovative activity in the given field. The actual multi-plan problem, chosen here as a topic of research, concerns regulations in management of wastes and secondary material resources in construction complex, in which economic, civil-law, ecological, social, industrial and legal relations are closely coordinated and define a subject of the present research. Production and consumption waste is a dangerous anthropogenic object of the environment but at the same time, it is a valuable secondary material resource. The non-use of wastes to be recycled as secondary raw materials for energy generation, production and, as a result, their increasing accumulation in the environment causes irreparable harm to natural objects and human health due to their dangerous properties. Research objectives: scientific and methodological substantiation of legal regulation, economic basis for formation of wastes and secondary material resources management system (on the example of construction complex and building materials industry

    Assuming an oil price of US$60 per barrel, both biodiesel and bioethanol produced from wheat are not profitable in Europe. The producers' high margins are only due to the current mineral oil tax concessions. At present, biomass-to-liquid (BTL) fuel also cannot be produced competitively. At the assumed oil price, only bioethanol and biobutanol produced on a large scale from lignocellulose-containing raw materials have the potential to be produced competitively. Analyses of the technologies used in this field show that in Europe there are interesting new technological developments for the hydrolysis, fermentation and purification step.

    This is the Final Report for a three-year (FY 92--94) study of the Environmental, Safety, and Economic (ESE) aspects of fusion energy systems, emphasizing development of computerized approaches suitable for incorporation as modules in fusion system design codes. First, as is reported in Section 2, the authors now have operating a simplified but complete environment and safety evaluation code, BESAFE. The first tests of BESAFE as a module of the SUPERCODE, a design optimization systems code at LLNL, are reported in Section 3. Secondly, as reported in Section 4, the authors have maintained a strong effort in developing fast calculational schemes for activation inventory evaluation. In addition to these major accomplishments, considerable progress has been made on research on specific topics as follows. A tritium modeling code TRIDYN was developed in collaboration with the TSTA group at LANL and the Fusion Nuclear Technology group at UCLA. A simplified algorithm has been derived to calculate the transient temperature profiles in the blanket during accidents. The scheme solves iteratively a system of non-linear ordinary differential equations describing about 10 regions of the blanket by preserving energy balance. The authors have studied the physics and engineering aspects of divertor modeling for safety applications. Several modifications in the automation and characterization of environmental and safety indices have been made. They have applied this work to the environmental and safety comparisons of stainless steel with alternative structural materials for fusion reactors. A methodology in decision analysis utilizing influence and decision diagrams has been developed to model fusion reactor design problems. Most of the work during this funding period has been reported in 26 publications including theses, journal publications, conference papers, and technical reports, as listed in Section 11

    Zulu sheep are Nguni sheep of Zululand and are adapted to the harsh conditions of KwaZulu-Natal. They are used by rural farmers for economic purposes. Their numbers are declining, indicating a potential extinction threat. Knowledge of their phenotypic and genotypic characteristics is essential for conservation planning. In this review, there is a focus on the utilization, socio-economic aspects, phenotypic and genotypic characteristics as well as a proposed breeding programme. A survey has shown that rural farmers in the areas of northern KwaZulu-Natal prefer to keep this breed for its adaptability, resistance to diseases and meat quality. Zulu sheep are small-framed multi-coloured animals. Mature males weigh up to 38 kg and females up to 32 kg. Based on four morphological traits and live weight, phenotypic diversity between three populations was estimated at 48%. A genetic diversity between these three populations was estimated at 22%. Live weight of Zulu sheep can be estimated using the heart girth and wither height measurements. Scrotum circumference of young rams (up to 22 months old) is reliable for estimating the live weight. Animals that were characterized in the studies were grazed extensively and no supplements were provided. There is therefore a potential of weight increase if these animals are reared in a semi-extensive environment. An open nucleus breeding scheme is thus recommended for a sustainable use and conservation of this breed. For more conclusive results, larger numbers of phenotypic and genetic characteristics, in larger numbers of Zulu sheep populations, should be investigated.

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

    This article aims at dealing with the historical development and the terminology of the notion of generation in ancient Greece, taking as well into consideration several aspects of the notion of heredity, for, at present, research in this field lacks a consistent encyclopedic entry on such subjects. The Presocratic - mainly Empedoclean - notions of 'mixing' and 'separation' lurk behind the Hippocratic treatise De genitura/De natura pueri, in which the process of generation is explained through the 'mixing' mechanism of a female semen and a male one. Semen comes from each part of both parents, so it is sound from the sound parts, and unhealthy from the unhealthy parts. It is considered as the "foam of blood" (Diogenes, A 24 DK), gathering itself into a web of blood vessels that bring it to the genital organs. The mixed semen keeps on fixing itself in the womb thanks to pneuma ('breath'), until the embryo takes human shape. Generation is influenced by both the environment (Airs, Waters, Places) and dietetics (On Regimen, I). Male and female are on different levels in CH, since the former is characterized as hot and strong, and the latter is considered as cold and weak; as a consequence of this, the articulation takes longer in the case of a female embryo. On the other hand, the pangenesis and the preformism theory claim for a strong mutual relationship. Sex determination depends from the 'prevalence' of the male or female semen. The generation of twins of different sex depends from such 'prevalence', as well as from the conformation of the womb and its places (right/male, left/female). Both nature (physis) and use (nomos) have a role in the mechanism of inheritance, as the case of the Macrocephalians in Airs Waters Places shows. On the other hand, Plato's Timaeus exemplifies the theory according to which semen derives from the spinal marrow. The structures of the body - bones, flesh, nerves - aim at protecting marrow itself for the sake of maintaining the continuity

    The next topics are represented in the paper: A brief history of WWER-1000 control rod (CR) and WWER-1000 rod cluster control assembly (RCCA) design; Evolution of WWER-1000 CR manufacturing technology and design; Experience of RCCA operation; Lifetime extension of WWER-1000 boron carbide CR; WWER-1000 reactor core operation problems due to partial RCCA insertion; Designing and licensing procedures and first operational experience of WWER-1000 RCCA (CR) with a combined absorber 'boron carbide-hafnium' and a chromium-nickel alloy cladding. The main conclusions are: Fuel assembly (FA) bow is the main reason of partial RCCA insertion during reactor core operation. However, the use of the RCCA and its driver bar with increased dead load, alongside with other measures, allow to reduce the probability of incomplete RCCA insertion; The materials used in CRs of RCCA in existing reactor operating modes have been working reliably; The use of hafnium under an appropriate price policy can give certain economic advantages for the Ukrainian NPPs, however, additional research is needed in order to confirm the specific CR physical characteristics and reliability.

    Wood biomass is an important renewable source of energy, especially in countries with traditional dependency on forestry resources. In these countries, wood biomass can have numerous positive socio-economical and environmental effects. This paper presents a new model (SCORE model) for estimation of 15 socio-economic and environmental aspects of increased use of biomass from the forests. The presented model enables selected estimation of different aspects in the whole chain of biomass production, preparation and use. Namely, the model enables the estimation of net labour income, net profit, regional public finance income, net direct jobs, net indirect jobs, net induced jobs, total net jobs, contribution to forest management, impact on wood waste utilisation, impact on other woody biomass utilisation, avoided costs of landfill, saving CO 2 emissions, possible impact on regional unemployment, avoided costs of unemployment, additional jobs for farmers, additional activities on farms (from indirect and induced jobs) and self-sufficiency in electricity production. The SCORE model was tested in selected regions in Slovenia and Croatia and apart from a good understanding of the socio-economic and environmental aspects, it also enables an overview of the economy of wood biomass production, given that it includes the economic analysis of wood biomass production and use. The model is not intended for a detailed economic analysis of separate phases of wood biomass production, processing and use, but particularly to show advantages or disadvantages that can result from planned and existing biomass systems.

    The decrease in background concentrations of particulate matter after 2000 is mainly caused by three years of strong decrease, two of which coincided with decreased economic growth. Recessions are an effective source measure and may be necessary for timely compliance with the European standards. [Dutch] De daling in de achtergrondconcentraties van fijn stof na 2000 blijkt vooral terug te voeren tot drie jaren met sterke daling, waarvan er twee samenvielen met verminderde economische groei.

    The NWFPs (non-wood forest products) sector is of the crucial importance to the Polish households but its social and economic role is varied and depends on place of residence. For the inhabitants of villages and small towns forests are the place of working and NWFPs sale provides an additional financial resource. City-dwellers do not treat NWFPs as a source of income but rather as an element of recreation and they use these products mainly for their own needs. Some remarks for the developing ...

    Traditional irrigation network around Mt. Kilimanjaro has been an important resource for both ecosystem functioning and agricultural production. However, a number of irrigation furrows can no longer maintain their discharge throughout the year and their future sustainability is uncertain. The actual efforts to improve the water supply were unsuccessful. We attribute this failure to a lack of information about the actual causes and extent of the problem. We suppose that there is a strong link between the socio-economic aspects like institutional and community management of the furrows and conflicts about water use. Therefore, we conducted a study to determine the relationship between current hydrological patterns and socio-economic aspects of agricultural water use. We measured discharge at 11 locations along an altitudinal gradient on the southern slopes of Mt. Kilimanjaro. Additionally, we conducted focus group discussions with participants from 15 villages and key informants interviews (n = 15). We found that the mean discharge did not differ significantly between dry and rainy seasons (ANOVA, p = 0.17). The overall discharge pattern indicated that furrows located in lower altitude had higher mean monthly discharge rate of 65 l s-1 compared to 11.5 l s-1 at the source area of the canals. This is due to the convergence of canals downstream. 41% of furrows were seasonal, 22% dry and only 37% perennial. Despite of a seemingly better water resource availability downstream, water conflicts are a major challenge across the whole mountain communities. Key informants and group discussions reported poor management of water on the district level. The Rural Moshi and Hai District Councils operate on a top down approach that give less power to the local water management committees. However, the latter have been an important part of the traditional management system for decades. Since 1990, the district authorities are using 65% of springs from the catchment to abstract water

    Reflection on Some Issues Regarding the System of Socialism with Chinese Characteristics Zhang Xingmao The establishment of the system of socialism with Chinese characteristics, as the symbol of China's entry into the socialist society with Chinese characteristics, is the significant development of Marist theory of social formation. The Chinese model is framed and defined by the socialist system with Chinese characteristics, therefore the study of different levels and aspects of the Chinese model should be related to the relevant Chinese system to guarantee a scientific interpretation. Under the fundamental system of socialism, the historical and logical starting point of the formation of socialism with Chinese characteristics lies in eliminating the private ownership first and then allowing the existence and rapid development of the non-public sectors of the economy. With the gradual establishment and on the basis of the basic economic system in the preliminary stage of Socialism, and with the adaptive adjustments in the economic, political, cultural, and social systems, the socialist system with Chinese characteristics is gradually formed.

    In view of the fact that in Japan treatment of end-stage renal disease depends disproportionately heavily on hemodialysis and almost negligible on transplants from cadaveric donors (hemodialysis 44.4/100,000; renal transplants 0.31/100,000 per year; cadaveric renal transplants 0.11/100,000 per year (1983 data)), we analysed the cost-effectiveness of hemodialysis and renal transplantation, predicted economic gains under expected changes in variables and described attitudes of the Japanese hampering cadaveric renal transplantation. Adjusted life expectancy of transplant recipients (live and cadaveric combined) under the current technical conditions is longer than that of those on hemodialysis (18.3 vs. 14.7 years) and the cost per year for maintaining the transplant is approximately one third of hemodialysis ($12,000 vs $32,000). If the proportion of cadaveric transplant recipients would increase to the levels of the USA (hemodialysis 30.8/100,000; transplants 2.6/100,000 per year; cadaveric transplants 1.9/100,000 per year (1983 data)) along with improvement in graft survival rate, the life expectancy for transplant recipients in Japan could increase by 2 years, thus reducing the annual cost even further. The current number of patients starting hemodialysis (11,500 cases per year) coupled with their life expectancy predicts the number of patients on hemodialysis to reach equilibrium at around 174,000 in a decade (Japanese population 110 million). Based on current price, their annual cost will be about 5.3 billion dollars. Medical expenditure of this magnitude for such a small fraction of people is expected to become an increasingly strong economic incentive for cadaveric renal transplantation. A review of studies on Japanese attitudes toward cadaveric renal transplantation in both urban and rural areas shows that approximately 60% are in favor of donating their kidney after death, though with the majority of cases the donation is contingent upon agreement of their

    Safety-technical characteristics of fuels, primarily biomass and, as reference, coal, have been studied at VTT Energy since the year 1993. The work has been related mainly to the development work of feeding and handling systems for pressurised gasification and combustion technology. Dust explosion and self-ignition characteristics of fuels have been determined in a number of research projects. Possible prevention of dust explosions with a suppression method immediately at ignition was studied in a project on suppression of dust explosions in biomass-utilising plants (Bioenergia Programme 1995). The first phase of dust explosion and suppression tests at elevated pressure were carried out in testing equipment of 5,6 m{sup 3} constructed, in particular, for these tests in Great Britain. Tests were made both with coal and wood powders by Coal Technology Development Division (British Coal Corporation) and Kidde Fire Protection. At the first stage of the test programme both coal and wood powder explosions were successfully suppressed at 10 bar pressure level. The current 1997-98 project includes the second phase of the explosion suppression tests, which will be carried out at 18 bar. If successful these tests would enable the extrapolation of the operation values to the pressure level of IGCC plants, i.e. to 20 - 25 bar. The boundary conditions set by safety factors on the design of pressurised (and atmospheric) feeding systems are fairly well-known due to data obtained from dust explosion and self-ignition experiments and from dust explosion suppression tests. The overall aim of the research is to compare pressurised system alternatives based primarily on lock-hopper feeding technology both technically and economically. A significant issue is how to arrange pressurisation and sufficient inertisation. New alternatives to produce inert gas will be assessed. The newest equipment, plug screw and piston feeders under development, will also be included in the study. The

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    The possibility to prevent the dust explosions by suppression method in the ignition stage has been investigated in the project `Suppression of dust explosions in biomass-fired plants` (Bioenergy Research programme 1995). The first stage of the dust explosion and suppression tests under elevated pressure were carried out in spring 1996 in England using the 5.6 m{sup 3} equipment constructed for this purpose. The tests were carried out both with coal and wood dusts. The tests were carried out by Coal Technology Development Division (British Coal) and Kidde Fire Protection. In the first stage of the project it was possible to suppress both the coal and wood dust explosions successfully at the 10 bar pressure level. The target of the second stage of the project is to carry out the tests also at 18 bar pressure level. These tests would, if successful, enable the extrapolation of the operational parameters the pressure levels of 20-25 bars of IGCC plants. The limiting factors for the planning of pressurized (and ambient pressure) feeding systems are now known relatively well on the basis of the knowledge gained in the dust explosion and self-ignition tests, and the dust explosion suppression tests. The total objective of the research is the comparison of pressurized feeding systems, based mainly on the lock-hopper technology, both in the economical and technical sense. Arrangement of pressurization and sufficient inertization form a significant factor. The newest pressurized double-screw and piston feeder technologies will also be considered. The second stage of the suppression tests has been carried out in the first stage of the project. The suppression tests were successful both with coal and biomass dusts when using four suppression media containers. The full pressure dust explosions were carried out successfully at 18 bar initial pressure 4 refs., 2 figs., 1 tab. Bioenergy Research programme

    The economic advantage of electricity-generating nuclear stations decreases when their size decreases. However, when a counter-pressure turbine is joined on to a reactor and the residual heat can be properly used, it can be shown that fairly low capacity nuclear equipment may compete with conventional equipment under certain realistic enough conditions. The aim of this paper is to define these special conditions under which nuclear energy can be profitable. They are connected with the location and the general economic environment of the station, the pattern of the electricity and heat demands it must meet, the level of fuel and specific capital costs, nuclear and conventional. These conditions entail certain technical and economic specifications for the reactors used in this way otherwise they are unlikely to be competitive.

    Full Text Available Estudos econômicos da adubação fosfatada fazem-se necessários, em razão da sua participação expressiva no custo de produção da cultura do milho, especialmente em solos sob vegetação de cerrado e face à competitividade da atividade no mercado globalizado. Assim, objetivou-se avaliar alguns aspectos econômicos de modos de aplicação da adubação fosfatada a lanço e sulco simples comparados ao modo alternativo em sulco duplo, utilizando o híbrido de milho BR 3123.

    Full Text Available The relative level of fiscal revenue in relation to the total aggregate domestic product or national income is a central indicator to be established in the national economy. This indicator is the “tax ratio”. The tendency of almost every economic and especially fiscal policy is that this indicator expresses the optimal ratio between the part of the domestic product or national income, which is intended to be used for the settlement of public needs and the general economic aggregate of the latter economic categories. Its special importance lies in the design concept of medium-term or long-term social and economic development. It is necessary to determine the framework of the global distribution of the domestic product or national income, which is acceptable, on the one hand, from the perspective of a balanced and stable economic growth, and on the other hand, from the standpoint of balancing interests of all social structures of modern mixed societies.
