    The speaker discussed the situation of gas supply and demand in the eastern part of North America. The first PowerPoint slide provided the outline of the presentation. The author showed maps detailing the regional gas demand, first in Ontario, Quebec and the Maritimes, then New England. The next few slides depicted the North American power generation capacity, and the market fundamentals of supply. The Canadian East Coast Forecast Production was shown, and the impact of liquid natural gas (LNG) and Sable deliveries through 2010 explained. The key themes for the next ten years were explored and the situation of Sable gas to Quebec as of 23 May 2001 was described. The implications for the Quebec market are many: Quebec is now receiving Sable gas and its connection with the Portland market is proving very useful. It all leads to growing confidence on the part of industrial gas users. The author concluded the presentation with a few thoughts: (1) moderate demand growth in Central Canada, (2) stronger growth in New England, (3) power generation is a key driver of demand, (4) LNG, East Coast and Arctic gas will be key supply sources, and (5) Sable gas to Quebec. figs

    Full Text Available The study presents current state of the national labor market and highlights its main trends. We have substantiated the necessity for building institutional support to the labor market in order to meet the needs of Ukrainian economy for innovative development in integrated environment. Measures for promotion of labor market in Ukraine should be: systematization of indicators evaluating its effectiveness; involvement in the assessment of both domestic and foreign experts; permanently identify weaknesses in the institutional support labor market; improving the infrastructure of the labor market. Of particular interest in promoting the efficient functioning of the labor market include the adoption of the concept that would provide incentives for innovative development of institutional support for the labor market. Important for rebirth of man's relation to labor should belong to such institutions as education, culture, family and church. Strategy for the development of effective national labor market should be based on the innovation focus of its institutions, to increase the competitiveness of the workforce and increasing the efficiency of its use in the region.

  7. Near-term market conditions

    International Nuclear Information System (INIS)

    Patterson, J.A.

    1979-01-01

    Information is reviewed available to DOE on uranium marketing and price situation. It is concluded that past procurement activity and slippage in needs has placed the uranium users in a comfortable supply position for the next few years. As a consequence, there has been a relatively low level of procurement activity the last few years, which have been accompanied by price stability. U.S. procurement has strongly favored U.S. suppliers, however, the potential exists for procurement of foreign uranium, particularly in long-term contracts. Domestic producers, having expanded their production and sales capability, will be in a strong position for deliveries over the next several years

  8. Marketing communications in conditions of crisis

    2009-01-01

    Full Text Available The paper aims to reveal potential economic benefits deriving from implementation of regionally integrated marketing communications strategy in the period of the global financial crisis. Possibilities for implementation of regionally integrated marketing communications strategy in the Western Balkans are analyzed based on the assessment of macro-marketing environmental factors and consumers attitudes. Study results have shown satisfactory conditions for the implementation of regionally integrated marketing communications in four countries of the region. Consequently, in the period of the most recent economic crisis companies operating on this market which decide to implement regionally integrated marketing communications strategy may make significant cost-savings through centralization of their marketing communications activities, organizational learning and synergy rather then from cutting their media budgets.

    2013-01-01

    Turkey's Energy Efficiency Law (EEL), enacted in 2007, had been expected to transform the energy policies in government and private sectors, and offer opportunities for, then-impending, Turkish Energy Service Company (ESCO) market. Yet, the communiqué of the EEL related to ESCOs was released only recently in July 2012. In this work, we review the current status of the ESCO market in Turkey. We provide an outlook through the recent legal communiqué and present barriers, enabling factors, and opportunities, supported by country's financial and economic facts. ESCO-financing mechanism prevailing and the sources of financing in the country are also mentioned. The communiqué on ESCOs fits well in the chain of regulatory attempts to increase Turkey's competitiveness in the global markets. However, we anticipate that some of its principles and procedures to be enforced may be deterrent for small-scale candidate ESCOs and may slow down the expected development of the Turkish ESCO market. Otherwise, the communiqué should lead restructuring of a stronger ESCO market in Turkey. - Highlights: • We review the current status of the ESCO market in Turkey. • We give outlook through the recent communiqué on ESCOs. • We provide view through financial and economic facts. • We present barriers, enabling factors, and suggestions

  11. Asymmetric conditional volatility in international stock markets

    Science.gov (United States)

    Ferreira, Nuno B.; Menezes, Rui; Mendes, Diana A.

    2007-08-01

    Recent studies show that a negative shock in stock prices will generate more volatility than a positive shock of similar magnitude. The aim of this paper is to appraise the hypothesis under which the conditional mean and the conditional variance of stock returns are asymmetric functions of past information. We compare the results for the Portuguese Stock Market Index PSI 20 with six other Stock Market Indices, namely the SP 500, FTSE 100, DAX 30, CAC 40, ASE 20, and IBEX 35. In order to assess asymmetric volatility we use autoregressive conditional heteroskedasticity specifications known as TARCH and EGARCH. We also test for asymmetry after controlling for the effect of macroeconomic factors on stock market returns using TAR and M-TAR specifications within a VAR framework. Our results show that the conditional variance is an asymmetric function of past innovations raising proportionately more during market declines, a phenomenon known as the leverage effect. However, when we control for the effect of changes in macroeconomic variables, we find no significant evidence of asymmetric behaviour of the stock market returns. There are some signs that the Portuguese Stock Market tends to show somewhat less market efficiency than other markets since the effect of the shocks appear to take a longer time to dissipate.

  13. Market conditions affecting energy efficiency investments

    International Nuclear Information System (INIS)

    Seabright, J.

    1996-01-01

    The global energy efficiency market is growing, due in part to energy sector and macroeconomic reforms and increased awareness of the environmental benefits of energy efficiency. Many countries have promoted open, competitive markets, thereby stimulating economic growth. They have reduced or removed subsidies on energy prices, and governments have initiated energy conservation programs that have spurred the wider adoption of energy efficiency technologies. The market outlook for energy efficiency is quite positive. The global market for end-use energy efficiency in the industrial, residential and commercial sectors is now estimated to total more than $34 billion per year. There is still enormous technical potential to implement energy conservation measures and to upgrade to the best available technologies for new investments. For many technologies, energy-efficient designs now represent less than 10--20% of new product sales. Thus, creating favorable market conditions should be a priority. There are a number of actions that can be taken to create favorable market conditions for investing in energy efficiency. Fostering a market-oriented energy sector will lead to energy prices that reflect the true cost of supply. Policy initiatives should address known market failures and should support energy efficiency initiatives. And market transformation for energy efficiency products and services can be facilitated by creating an institutional and legal structure that favors commercially-oriented entities

  15. STAFF MARKETING IN MODERN RUSSIAN CONDITIONS

    Directory of Open Access Journals (Sweden)

    Nataliya N. Kretova

    2017-09-01

    Full Text Available The conception of staff marketing, which was developed abroad, is effectively used in the developed countries for a long time. Its main advantage consists in the possibility of organizing some planning for the implementation of staff strategy: staff marketing provides the enterprise on the long-term basis with human resources capable of forming strategic potential, which would allow to implement the planned activities. Numerous problems of formation and development of civilized market relations in our country do not allow to fully implement the detailed models of staff marketing in domestic realities. On the basis of the analysis of theoretical developments and factors that have a practical impact on the implementation of marketing personnel in modern Russian conditions, the authors describe the essential elements of the conception. The primary purposes of staff marketing for domestic enterprises, grouped into the internal and external marketing are substantiated and disclosed. The special attention is paid to increasing the staff loyalty, which has dominant influence on business outcomes. The algorithm of events for the development of motivation system is proposed; at the stage of studying job satisfaction it is recommend to apply analytical calculations with the use of Shewhart control charts. Unlike traditional statistical tools based on the inspection of already implemented results, this approach is aimed at preventing negative tendencies and avoids losses associated with dissatisfaction with difficulty, as the individual employee and the team as a whole. Modern Russian enterprises can fully realize the conception of staff marketing only through rethinking of the consequences for all directions of work with the staff, as reflected in the definition of objectives, motivating staff and ensuring social responsibility of the enterprise.

    with the liberalisation process of the energy sectors of the EU countries, it is however anticipated that Danish local CHP are to begin operating on market conditions within the year 2005. This means that the income that the local CHPs previously gained from selling electricity at the feed-in tariff is replaced in part...... the consequences of acting in a liberalised market for a given CHP plant, based on the abovementioned bottom-up model. The key assumption determining the bottom line is the electricity spot price. The formation of the spot price in the Nordic area depends heavily upon the state of the water reservoirs in Norway...

  17. The Current Developments of Agricultural Biotechnologies Market

    Directory of Open Access Journals (Sweden)

    Anna M. Shkolyarenko

    2016-01-01

    Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

    1993-01-01

    The main dilemma of energy sector in market conditions is: regulation of the monopole producer and/or competition. There is no simple answer and the arguments for and against should be based on the macro economical determination of what kind of market is available for particular energy goods (perfect, monopolistic, oligopolistic, competition of monopolists) and what is the final purpose (improvement in efficiency, service, energy independence, regional development, etc.). Two polar models of economic management in energy sector are distinguished: 1) Free access to transfer net or competition between producers. 2) State regulation of the local monopolist. The experience of Great Britain and US are described as examples of both models. A special attention is paid to pricing methods at regulated monopole. 7 refs. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Breuer, Daniel [Landgericht Koeln (Germany); Osborne Clarke, Koeln (Germany). Bereich Energierecht

    2012-07-01

    The new direct marketing regime of the EEG 2012 provides incentives for operators of renewables-based systems to leave the fixed reimbursement scheme and integrate their systems in the markets, especially in the context of marketing of regulating power. However, it remains to be seen if this will reduce the cost of regulating energy supply, or at least keep it at the current level. In any case, plant operators should be careful in choosing their direct marketers and other partners and consultants. Simultaneous supply of regulating power is attractive especially for controllable and in some cases also for fluctuating renewable energy sources. This does comply with the priority principle and also with the prohibition of double marketing as is clearly stated in SEction 8 No. 3a.

  3. Hydro investment analysis under new market conditions

    Energy Technology Data Exchange (ETDEWEB)

    Doorman, Gerard

    2010-07-01

    Full text: A future energy system with stronger coupling to Europe and with an increased share of non-regulated renewables will lead to increasing variability of the demand faced by the hydro system. In a market based system these variations will be reflected by larger daily price variations, both in the Elspot day ahead market, the Elbas intraday market and in the balancing market. With its unique regulation capabilities, hydro power will be very well positioned to handle these variations. However, existing model concepts for long term hydro scheduling were not developed for this framework, and do not take the new market conditions into account to a sufficient degree. Therefore hydro scheduling tools used for upgrading and investment analysis as well as analysing consequences of new environmental demands need adaptation to a finer temporal resolution, and to perform optimisation under varying constraints and uncertain input data for inflow and electricity prices. Focus is on investment analysis for a river system or power producer. Existing models can be grouped in the long-term (scheduling models with a time horizon up to 5 years) EOPS (Vansimtap), EOPS-ST (SimtapEffekt) and ProdRisk, and the shortterm scheduling models with a typical time horizon up to a few weeks, but focus on 1-2 days (SHOP and ID-SIM). A perfect tool in the present context would combine the properties of the long term stochastic optimisation models with the modelling details of SHOP and/or ID-SIM. However, this is probably not possible and simplifications will be necessary. Some important deficiencies in the present long term models are: Insufficiently realistic plant models in the relevant optimization models; Time delays are not handled; Handing of flexible / state dependent constraints; Handling of ramping constraints; Modelling of the cost of frequent regulations (wear and tear); Reserve markets As a result of these deficiencies the investment analysis does not adequately assess the value

  4. Current perspective of the uranium enrichment market

    Laughon, K.O.

    1986-01-01

    Over the past several years, developments in the uranium enrichment market have required the Department of Energy (DOE) to make a number of changes in the U.S. enrichment enterprise. These changes have been made to allow DOE to conduct our enrichment business so as to be more responsive to changing market forces. Needless to say, some of these changes have been difficult, but they have been necessary if they are to conduct a healthy and competitive uranium enrichment business in the United States. This paper discusses several topics, including: The Uranium Enrichment Market, Utility Services (US) Contracts, Reduced Prices, Incentive Pricing, Better Customer Services, and Advanced Technology. In addition to these topics, information is provided on the recent court action regarding the US Contracts and the viability finding on the uranium mining industry

    Paks Nuclear Power Plant is the only nuclear power plant in Hungary covering 38% of electricity consumption in the country. The nuclear electricity production of the four VVER440/213 type units in the year of 1999 was 14096 GWh, the second best result in the history of the company. After very detailed safety analyses Paks NPP started a safety upgrading program in 1996, and today the CDF values of the reactor units reached an internationally accepted value. The operational and safety culture and the level of safety was evaluated and reviewed by different international organizations like the IAEA, WENRA, WANO. Based on the conclusions of these international organizations the Paks plant w111 be ready for EU accession after the completion of the ongoing safety upgrading program. Capacity enhancement as a part of the preparation for the market conditions resulted a power upgrade around 20 MW for all four units. This way a relatively small investment in comparison with new installations resulted more efficient to market nuclear capacity. Last year the cost of a generated 1 kWh electricity was 5.98 Ft, which is still to be decreased in 2000. To upgrade the competitiveness of nuclear generation lots of efforts were done in the areas of plant management cost reduction, man-power efficiency upgrade. Un-bundling of activities not directly related to electricity generation in one hand, and more efficient cooperation with other VVER operators and the Hungarian Power Companies Ltd. in certain areas on the other hand are good examples for efficient steps in economic improvement. The company as one of the electricity producers also should follow the capabilities of producers in the neighboring countries like Slovakia and Ukraine, where electricity production is with government subsidiary. To find the right balance between the necessary investments and the market induced cost reduction is one of the most important task in Hungary in Eastern-Europe especially when the nuclear energy

  19. Direct-to-consumer marketing of prescription drugs: a current perspective for neurologists and psychiatrists.

    Hollon, Matthew F

    2004-01-01

    In the US and New Zealand, the past decade has seen tremendous growth in the marketing of prescription drugs directly to patients. The pharmaceutical industry has applied pressure in other countries to relax regulations governing such marketing although this has not yet been successful. While we still have much to learn about the potential impact on the public's health of direct-to-consumer (DTC) marketing, some data are available. This article summarises the current literature on the benefits and risks of DTC marketing. This marketing strategy has grown substantially in the US, but only select drugs are advertised. Whether there is net benefit or harm to the public's health as a result of DTC marketing depends critically on which drugs are advertised and the quality of the information provided in promotional material. Critical reviews of this promotional material suggest the information is of poor quality. Notably, 18% of the 50 drugs advertised most intensively in the US were medications used to treat psychiatric and neurological disorders. The impairments in decisional capacity often seen in psychiatric and neurological illness leave patients vunerable to the controlling influence of DTC marketing and, thus, undermine the patient autonomy that is said to be promoted by this marketing strategy. If there is any benefit from DTC marketing it is for significantly undertreated conditions. International restrictions on DTC marketing should remain in place until further evidence of net benefit or harm emerges from the DTC marketing experiment that is taking place in the US and New Zealand.

    We show that the current economic crisis has led the market to exhibit a non-critical behavior. We do so by analyzing the quantitative parameters of time series from the main assets of the Brazilian Stock Market BOVESPA. By monitoring global persistence we show a deviation of power law behavior during the crisis in a strong analogy with spin systems (from where this concept was originally conceived). Such behavior is corroborated by an emergent heavy tail of absolute return distribution and also by the magnitude autocorrelation exponent. Comparisons with universal exponents obtained in the international stock markets are also performed. This suggests how a thorough analysis of suitable exponents can bring a possible way of forecasting market crises characterized by non-criticality.

    Full Text Available The conditional CAPM is characterized by time-varying market beta. Based on state-space models approach, beta behavior can be modeled as a stochastic process dependent on conditioning variables related to business cycle and estimated using Kalman filter. This paper studies alternative models for portfolios sorted by size and book-to-market ratio in the Brazilian stock market and compares their adjustment to data. Asset pricing tests based on time-series and cross-sectional approaches are also implemented. A random walk process combined with conditioning variables is the preferred model, reducing pricing errors compared to unconditional CAPM, but the errors are still significant. Cross-sectional test show that book-to-market ratio becomes less relevant, but past returns still capture cross-section variation

  8. The money market in Montenegro: Conditions, development and outlook

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available The money market represents a segment of financial markets wherein the objects of trading are funds with short-term maturities. The money market in Montenegro is still in its early stages of development, and is characterized by a narrow scope of trading material and by a relatively narrow variety of participants. The reasons for such slow development of the Montenegrin money market are numerous: lack of regulations, dollarization as a model of monetary and foreign exchange regime, excessive liquidity of domestic banks, insufficient liquidity in the corporate sector, limited protection of creditor rights, and minimal corporate transparency. Short-term government bonds ("T-bills"-traded exclusively on the primary market-are the only short-term securities on the Montenegrin money market. Montenegrin banks are the biggest investors in T-bills. Foreign investors withdrew from the primary T-bill market after a decrease in T-bill interest rates. For a while, many considered that inadequate solutions in the Law on Securities were the main setbacks to organizing a secondary T-bill market. However, amendments to this Law did not spark the development of a T-bill market, nor any other short-term securities market. Adequate legislation is essential for the development of the money market, but it is not a sole precondition. A decrease in banks’ liquidity (as competition from other financial institutions increases and/or deposit interest rates decline is important to induce the money market’s development. We can expect a concurrent decrease in lending interest rates only as the conditions of creditor rights protection and business operations transparency improve. Only under such conditions can we expect banks and other financial and non-financial legal entities to begin issuing short-term securities.

    Full Text Available Introduction. Modern insurance companies provide the formation of effective market mechanisms for attracting investment resources to the national economy through the effective functioning of the insurance market with the use of modern market infrastructure and financial instruments. In Ukraine, the insurance market has a significant development potential, which requires, first of all, a detailed assessment of all available opportunities for balanced development in the context of European integration processes. Therefore, the identification and analysis of modern trends in the development of the insurance market are relevant today from theoretical and practical points of view. The purpose of the study is to analyze the current state of the insurance market in Ukraine and determine the factors affecting the effectiveness of its activities. Results. It was defined that the insurance market is the second largest in terms of capitalization among other non-bank financial markets in Ukraine. The tendencies of changes in the main indicators of the insurance market activity, in particular regarding the number of concluded insurance contracts, insurance premiums and insurance payments, reinsurance, insurance reserves, insurers’ assets and authorized capital, were investigated. It was found that the increase in gross insurance premiums was made for almost all types of insurance, and the increase of gross insurance premiums was mainly due to auto insurance, medical insurance and financial risk insurance. Nowadays, the level of insurance penetration in Ukraine is still low. However, according to the Comprehensive Program for the Development of the Financial Sector of Ukraine, a gradual increase of this indicator is planned. Conclusions. The conducted studies indicate that the insurance market of Ukraine is at the stage of formation, gradually adapting to the requirements of European and world markets. In order to improve the situation, domestic insurers

    The renewable energy sources are promoted by their beneficial use, namely: - diversification of energy sources for producing electric power; - reduction of pollution produced by fossil fuel burning; - reduction of gas releases producing the greenhouse effects, etc. Currently, most of the renewable energy sources cannot concur on electric power free market because of the high costs of implied investments. To ensure an efficient use of renewable energy sources in electricity production and to maintain the installations implied on the electric power market, it is necessary to implement a system able to produce an output greater than that obtained from electric energy selling. The Romanian Government chose to promote the electric energy production by renewable energy sources by using the green certificate trading system. This system ensures the progress in developing the technologies employed in electric energy production from renewable energy sources and, at the same time the costs implied by their promotion can be adjusted by market mechanisms what will reduce the effects upon the electric energy consumers. The paper presents the legislation frame existing in Romania for promoting the electric energy produced from renewable energy sources, the green certificate trading system applied in Romania, as well as, the role shared by the entities implied in operation and development of the system. In November 2005, a first transaction with green certificates on controlled green certificate market in Romania took place. Analyzed is the evolution of the green certificate market registered so far from its inception, as well as, the lessons learned so far from the experience acquired

Thus, the objective was to evaluate the microbiological quality of eggs marketed out at Sinop – MT, through the identification of Salmonella spp., count of aerobic mesophile bacteria and enterobacteria. We collected 12 eggs from each establishment, three supermarkets and three fairs. Were not identified Salmonella spp. in egg shells and internal content. Escherichia coli was isolated from the internal contents of eggs come from an street fair. In aerobic mesophilic counts were obtained from eggs supermarkets counts CFU/g/egg shell of 5,8 x 105, 1,21 x 105 e 4,7 x 103. In relation to the fairs, the counts were 7,2 x 104, 5,66 x 104 e 8,7 x 103. The absence of Salmonella spp. the evaluated eggs classifies them as fit for consumption for compliance with current legislation. However, the presence of E. coli and the values of aerobic mesophilic counts and Enterobacteriaceae highlight the need to establish measures to reduce bacterial contamination of shell eggs sold out at Sinop, MT.

    2006-01-01

    Marketing is widely recognized as an essential business function across all industries, including healthcare. While many long-term care facilities adopted basic healthcare marketing practices and hired marketing staff by the early 1990s, a paucity of research on nursing home marketing exists in the literature. This study examines the extent to which nursing homes have developed more formulated marketing and related communication and promotional strategies as market competition has increased in this sector during the past two decades. In addition, we explored managers' perceptions of their control over marketing decision making, the impact of competition on the use of marketing practices, and areas for enhanced competitive positioning. Administrators from 230 nursing homes in 18 Southeastern Michigan counties were surveyed regarding (1) the adoption level of approximately 40 literature-based, best-practice marketing strategies; (2) the types of staff involved with the marketing function; and (3) their perception of their level of control over marketing functions and of local competition. Results from 101 (44 percent) survey participants revealed that although respondents viewed their markets as highly competitive, their marketing practices remained focused on traditional and relatively constrained practices. In relation to the importance of customer relationship management, the majority of the administrators reported intensive efforts being focused on residents and their families, referrers, and staff, with minimal efforts being extended to insurers and other types of payers. A significant positive relation was found between the intensity of marketing initiatives and the size of the facility (number of beds), whereas significant negative correlations were revealed in relation to occupancy and the perceived level of control over the function.

    Full Text Available Analysing the possibility of creations and prospects of weather derivatives development on the domestic market the first of all should be identify the business areas that are strongly exposed for weather risk, which are: energy, agricultural, building and transportation. The specificity of the Polish climate is the high volatility of the major weather factors like temperature or precipitations. Similar to other European countries where weather derivatives markets already exist (e.g.: Germany, France, and United Kingdom. Having in mind dynamic grow of companies with regards to management processes, used technologies and marketing strategies, the exposure for weather risk is getting higher. Therefore, there is a strong pressure for creation of mechanisms and instruments that will allow reducing that kind of risks. Currently in Poland there are no conditions for development of weather derivatives market due to lack of demand. That situation is caused by low level of awareness regarding to possibilities of reducing weather risks. Within a few years the demand for such the instruments will appear ñ together with growing awareness. Once the demand for weather derivative will appear, the existing infrastructure of financial sector is ready for its implementation. Of course it is hard to say what will be the direction of whether derivatives grow on the domestic financial market but taking into consideration its dynamic grow and strong correlations with global markets, there is a small probability that weather derivatives will not appear on the Polish market ñ it is only the matter of time.

    International Nuclear Information System (INIS)

    1994-07-01

    The aim of this study is to analyze the prerequisites for biofuel-based cogeneration plants and for wind power, with special emphasis on following factors: 1/ The effect on the Swedish energy market of the opening of the power transmission networks for free competition within the electric power supply sector. 2/ A market model for the connection between the prices on fossil fuels, biomass fuels, electric power, and heating on the Swedish market. The analysis is made for three scenarios concerning carbon dioxide/energy taxation and the oil price development. The three scenarios are: A. Constant prices on heating oil and coal., B. An internationally uniform carbon dioxide tax, which successively is raised to SEK 0.40 per kilo carbon dioxide to the year 2010. In the year 2005 this will correspond to a doubling of the present prices on crude oil., C. An unilateral Swedish energy- and carbon dioxide tax of todays model (without exception for electric power generation), with constant import prices on heating oil and coal. The decisive factors for bio-cogeneration are construction- and operation costs, the costs of biofuels, and the sales price on electric power and heat. For wind power it is the construction- and operation costs that settle the conditions. 18 figs, 6 tabs

    Campbell, B.

    2001-01-01

    The focus of this presentation was on the governance, operation and regulation of the Independent Market Operator (IMO) in a competitive electricity market in Ontario. The presentation also included an update on the progress toward market readiness and discussed the principles guiding government decision making, recognizing that it is government that holds the decision on the market opening date. The IMO has been running Ontario's bulk electric system for more than 50 years, overseeing its safe and reliable operation while balancing demand and supply. IMOs are also leading the drive to a competitive, deregulated wholesale electricity marketplace in Ontario. When open, IMOs will run the electricity spot market, collecting offers from suppliers and bids from purchasers to determine a spot market price for electricity which will reflect demand across the province. Rules and processes are being developed to ensure the Ontario marketplace will operate to benefit both consumers and producers. The four principles guiding governments in the opening of electricity markets are to protect consumers and offer more choice, ensure a strong business climate with a reliable supply of electricity, to protect the environment, and to support alternative sources of power

    Past and recent factors point to a remarkable growth of the Asian market in the medium and long term. This growth will depend on structural and institutional evolutions on the Asian market. Some regulatory and liberalization reforms have already been initiated to support the development of gas but this will require a long process. Oil-indexing will prevail for a long time (but which slope?) Supply flexibility must be improved (relaxation of destination clauses, quantity tolerances) to create a competitive gas market. Marketing innovations expected in new long-term contracts to enhance flexibility whilst preserving investment security. A growing portfolio approach (LNG portfolio, pipeline imports, unconventional gas) is implemented. In conclusion, regional cooperation among Asian buyers is very important

    Full Text Available The global meat market and primarily the chicken meat market represents a very dynamically developing area. The objective of the present article is the analysis of the chicken meat market in the world in order to identify the basic development trends associated with the development of production of and trade in chicken meat, and also in order to identify the individual entities controlling the global chicken meat market. In methodological terms, the article analyzes the development of production of, consumption of and trade (export and import in chicken meat in the years 1961–2009. The main sources of data necessary for the processing of the individual analyses are the FAOSTAT and UN COMTRADE databases. The results of the conducted analysis show the following findings. World production of poultry meat increased from 7.5 million tons to more than 86 million tons. The global market reacted in a flexible manner, in which there was an increase in volumes of executed trade from 271 thousand tons/year in the year 1961 to more than 10.7 million tons/year in the year 2010. Further, the value of world trade in chicken meat within the analyzed period increased from approximately USD 169 million to approximately USD 16 billion. If we analyze the global chicken meat market, it may be stated that it is very concentrated. The analysis of the global market further shows that Brazil, the USA and China represent, in terms of global production, consumption and trade, the main driving force on the chicken meat market. These three countries have a share in global production of approximately 46%, their share in global consumption ranges at a level of over 40%. The share of these countries in global export ranges at a level exceeding 50%.

  3. Everyday, everywhere: alcohol marketing and social media--current trends.

    Nicholls, James

    2012-01-01

    To provide a snapshot content analysis of social media marketing among leading alcohol brands in the UK, and to outline the implications for both regulatory policies and further research. Using screengrab technology, the complete Facebook walls and Twitter timelines for 12 leading UK alcohol brands in November 2011 were captured and archived. A total of 701 brand-authored posts were identified and categorized using a thematic coding frame. Key strategic trends were identified and analysed in the light of contextual research into recent developments in marketing practice within the alcohol industry. A number of dominating trends were identified. These included the use of real-world tie-ins, interactive games, competitions and time-specific suggestions to drink. These methods reflect a strategy of branded conversation-stimulus which is favoured by social media marketing agencies. A number of distinct marketing methods are deployed by alcohol brands when using social media. These may undermine policies which seek to change social norms around drinking, especially the normalization of daily consumption. Social media marketing also raises questions regarding the efficacy of reactive regulatory frameworks. Further research into both the nature and impact of alcohol marketing on social media is needed.

  8. The current state of the market for corporate acquisitions

    International Nuclear Information System (INIS)

    Korpach, A.N.

    1998-01-01

    The main factors which determine when the oil and gas industry is in a seller's market or a buyer's market mode were discussed. In a seller's market, the number of potential buyers for assets exceeds the number of sellers. Therefore, sellers could obtain good prices for their assets. Such was the case from 1995 to 1997. For 1998, the level of merger and acquisition activity was high and is expected to remain strong for 1999, but the market appears to be firmly a buyer's market (more sellers than potential buyers). The reasons for this are as follows: (1) restricted access to capital, (2) declining stock prices/values, (3) significant supply of assets, and (4) acquisition costs now in line with finding and development costs. The question of whether or not acquisitions add value was also discussed. It was noted that share price performance of those companies making acquisitions during the period was comparable to that of the TSE oil and gas producers index. A list of some Canadian and U.S. companies which completed significant acquisitions in 1997 and 1998 was included. 10 figs

  12. CONSIDERATIONS REGARDING REGULATIONS ON FINANCIAL MARKETS IN THE CONDITIONS OF ROMANIA AS A EU MEMBER STATE

    Directory of Open Access Journals (Sweden)

    ALEXANDRU CRISTIAN DOBRE

    2018-02-01

    Full Text Available Financial markets are increasingly becoming an area of major interest to the European Union in its efforts to achieve competitive global development levels similar to those of the United States. The Lisbon Agenda is a testimony to this, although the latest assessments are not at all optimistic about the achievement of the target as expected for 2010. To meet its objectives, the EU has generated a comprehensive package of regulatory initiatives, composed of directives and regulations that translate its policies into the field. The paper aims at a careful review of all of them. Approximation of investment and capital markets is made from the two major chapters of Community policies whose freedom of movement within the internal market is a fundamental desideratum of the European Union: the free movement of capital and freedom of movement of services. Financial markets are an integral part of European capital under current conditions, so development regulation helps European Union member states achieve their financial goals. At the same time, by imposing these regulations, we observe the European Union's intention to act as a starter of systems to bring to the development of states and not to leave behind the countries that are in difficulty, through a rigorous and transparent regulation of the financial markets.

    2015-09-01

    Full Text Available During non-severe fault conditions, crowbar protection is not activated and the rotor windings of a doubly-fed induction generator (DFIG are excited by the AC/DC/AC converter. Meanwhile, under asymmetrical fault conditions, the electrical variables oscillate at twice the grid frequency in synchronous dq frame. In the engineering practice, notch filters are usually used to extract the positive and negative sequence components. In these cases, the dynamic response of a rotor-side converter (RSC and the notch filters have a large influence on the fault current characteristics of the DFIG. In this paper, the influence of the notch filters on the proportional integral (PI parameters is discussed and the simplified calculation models of the rotor current are established. Then, the dynamic performance of the stator flux linkage under asymmetrical fault conditions is also analyzed. Based on this, the fault characteristics of the stator current under asymmetrical fault conditions are studied and the corresponding analytical expressions of the stator fault current are obtained. Finally, digital simulation results validate the analytical results. The research results are helpful to meet the requirements of a practical short-circuit calculation and the construction of a relaying protection system for the power grid with penetration of DFIGs.

    2009-01-01

    Decentralized wind, hydropower, biogas and biomass, geothermal, solar thermal and solar electricity energy systems are the most commonly found renewable energy technologies promoted for rural energy supply within sustainable developments programs. They are, therefore, seen to have a central place in the practice of sustainable development and in allowing less development countries to bypass the environmentally damaging fossil fuel intensive paths made by industrialized countries. On the political front, many less development countries are critical of pressure on them to adopt environmental energy technologies. Turkey is situated the meeting point of three continents (Asia, Europe and Africa) and stands as a bridge between Asia and Europe. The country is located in southeastern Europe and southwestern Asia. As Turkey's economy has expanded in recent years, the consumption of primary energy has increased. Presently in order to increase the energy production from domestic energy resources, decrease the use of fossil fuels as well as reduce of green house gas emissions different renewable energy sources are used for energy production in Turkey. The share of energy production from renewable energy sources has increased during the last 10 years. Turkey must import most of the energy to meet her needs. Turkey also has a large potential for renewable energies. The lack of knowledge about renewable energy technologies by most policy-makers, potential consumers, and energy firm managers has played against renewable energy developments. The paper presents renewable energy used in Turkey and Europe Union and evaluation of the market conditions and barriers of renewable energy use in Turkey. (author)

  7. Condition monitoring of machinery using motor current signature analysis

    International Nuclear Information System (INIS)

    Kryter, R.C.; Haynes, H.D.

    1989-01-01

    Motor current signature analysis (MCSA) is a powerful monitoring tool for motor-driven equipment that provides a nonintrusive means for detecting the presence of mechanical and electrical abnormalities in the motor and the driven equipment, including altered conditions in the process ''downstream'' of the motor-driven equipment. It was developed at the Oak Ridge National Laboratory as a means for determining the effects of aging and service wear systems, but it is applicable to a broad range of machinery. MCSA is based on the recognition that an electric motor (ac or dc) driving a mechanical load acts as an efficient and permanently available transducer by sensing mechanical load variations, large and small, long-term and rapid, and converting them into variations in the induced current generated in the motor windings. These motor current variations are carried by the electrical cables processes as desired. Motor current signatures, obtained in both time and over time to provide early indication of degradation. Successful applications of MCSA technology (patent applied for) include not only motor-operated valves but also pumps of various designs, blowers, and air conditioning systems. Examples are presented briefly, and speculation regarding the applicability of MCSA to a broader range of equipment monitoring and production line testing is also given. 1 ref., 13 figs

Using a novel 2D multi-fluid model, current density during Glow Discharge Conditioning (GDC) on the in-vessel plasma-facing components (PFC) of ITER is predicted to approach the simple expectation of total anode current divided by wall surface area. Baking of the divertor to 350 °C should desorb the majority of the co-deposited T. ITER foresees the use of low temperature plasma based techniques compatible with the permanent toroidal magnetic field, such as Ion (ICWC) or Electron Cyclotron Wall Conditioning (ECWC), for tritium removal between ITER plasma pulses. Extrapolation of JET ICWC results to ITER indicates removal comparable to estimated T-retention in nominal ITER D:T shots, whereas GDC may be unattractive for that purpose.

  10. Market potential of superconductor current limiters; Marktpotential von supraleitenden Strombegrenzern

    This final report for the Swiss Federal Office of Energy describes the two concepts - 'resistive' and 'inductive' - used for Superconducting Fault Current Limiters (SCFCL) that utilise the transition from zero to finite resistance to limit short-circuit currents. The main advantages of SCFCL are compared to other current-limiting technologies: They can limit any type of prospective fault current, operate fail-safe, be self-triggered and self-restoring. Their main disadvantage - the cooling effort necessary - is also discussed. The application possibilities of SCFCL were investigated by simulating the impact on utility and industrial grids. Applications of SCFCL such as the coupling of medium-voltage grids and their use in series with a circuit-breaker on the secondary side of a substation transformer are discussed. It is also shown that, by using fault current limiters, considerable cost savings can be made, especially in connection with new installations or the extension of existing plants.

  11. Surviving and thriving in the current and future Nigerian petroleum products market

    International Nuclear Information System (INIS)

    Ali, Y.G.

    1998-01-01

    Currently, the petroleum products market is totally regulated. The operations and pricing mechanism must be conducted under prevailing Government rules and regulations. Indeed, in Nigeria today, no industry is as regulated as the Oil Industry (downstream emphasised) - which constitute the totality of petroleum products market. This situation has arisen as a result of the seeming classification of the oil industry as being strategic. Due to the regulations of the market, it can no longer adapt to the changing economic trend of liberalization and interplay of market forces, even when under serious pressure to yield to the dynamics of free market enterprise. As a result of the resistance to change, the market becomes stressed and over-burdened by the shackles of regulation which leads to a breakdown of the system and the impact becomes noticeable almost immediately. Needless to emphasize that, for the petroleum products market to survive and thrive, a cursory look at what obtains currently would afford us the opportunity to access the strength and weaknesses of such system, with a view to ascertaining the survival strategy to be applied for sustainable growth. In addition, a serious examination of the roles being played by the key operators in the petroleum products market otherwise called down stream operators (refineries, pipelines and marketers) is imperative. Since it requires the co-operation of the operators to achieve synergy in the market, any bottleneck arising from any of the sub-sectors has the capacity to disrupt the system

  13. Toroidal current asymmetry and boundary conditions in disruptions

    Science.gov (United States)

    Strauss, Henry

    2014-10-01

    It was discovered on JET that disruptions were accompanied by toroidal asymmetry of the plasma current. The toroidal current asymmetry ΔIϕ is proportional to the vertical current moment ΔMIZ , with positive sign for an upward vertical displacement event (VDE) and negative sign for a downward VDE. It was claimed that this could only be explained by Hiro current. It is shown that instead it is essentially a kinematic effect produced by the VDE displacement of a 3D magnetic perturbation. This is verified by M3D simulations. The simulation results do not require penetration of plasma into the boundary, as in the Hiro current model. It is shown that the normal velocity perpendicular to the magnetic field vanishes at the wall, in the small Larmor radius limit of electromagnetic sheath boundary conditions. Plasma is absorbed into the wall only via the parallel velocity, which is small, penetrates only an infinitesimal distance into the wall, and does not affect forces exerted by the plasma on the wall. Supported by USDOE and ITER.

    The Swedish gas market consists mainly of the natural gas network that extends through the southwestern Sweden, and the local biogas markets. Biogas share of the Swedish gas market is growing steadily. The fact that the Swedish gas net is limited and fragmented forms an obstacle for biogas use to expand. That the gas market as a whole, natural gas included, must develop and expand is therefore a prerequisite for the large potential for Swedish Biogas to be realized. This in contrast with the ultimate objective to completely replace natural gas in the Swedish gas market. When policy changes are made in order to support biogas it is crucial for long-term competitiveness of biogas that these changes should not impact the natural gas market and hinder its development. Such a scenario would ultimately mean that also biogas development opportunities deteriorate. Biogas operations encounter three main problems that prevent or impede its expansion in the gas market. First, the potential for profitability in biogas production must be enhanced. Second, natural gas and biogas markets should be more integrated with each other. Thirdly, the biogas must be distributed in a cost-effective manner. The present investigation aims to supplement the Natural Gas Act with special provisions which takes into account the input and transmission of biogas. In addition to the production of biogas, it is now the producer's responsibility to clean the gas from water vapor, hydrogen sulfide and carbon dioxide and to augment the calorific value of the gas to the standard of Danish natural gas quality by propane addition and to ensure that the physical connection to network is available. There are thus a number of options available for shifting demarcation between biogas production and network operations. Short-term competitiveness of biogas would be strengthened most if purification and spiking the gas with propane and the connection to the network was imposed on network owners. In the

  16. Utility residual fuel oil market conditions: An update

    International Nuclear Information System (INIS)

    Mueller, H.A. Jr.

    1992-01-01

    Planning for residual fuel oil usage and management remains an important part of the generation fuel planning and management function for many utilities. EPRI's Utility Planning Methods Center has maintained its analytical overview of the fuel oil markets as part of its overall fuel planning and management research program. This overview provides an update of recent fuel oil market directions. Several key events of the past year have had important implications for residual fuel oil markets. The key events have been the changes brought about by the Persian Gulf War and its aftermath, as well as continuing environmental policy developments. The Persian Gulf conflict has created renewed interest in reducing fuel oil use by utilities as part of an overall reduction in oil imports. The policy analysis performed to date has generally failed to properly evaluate utility industry capability. The Persian Gulf conflict has also resulted in an important change in the structure of international oil markets. The result of this policy-based change is likely to be a shift in oil pricing strategy. Finally, continued change in environmental requirements is continuing to shift utility residual oil requirements, but is also changing the nature of the US resid market itself

    2015-08-01

    In the past decade, many guidance documents have been issued through collaboration of global organizations and regulatory authorities. Most of these are applicable to new products, but there is a risk that currently marketed products will not meet the new compliance standards during audits and inspections while companies continue to make changes through the product life cycle for continuous improvement or market demands. This discussion presents different strategies to bringing drug product marketing applications to meet current and emerging standards. It also discusses stability and method designs to meet process validation and global development efforts.

  5. Wind power and the conditions at a liberalized power market

    International Nuclear Information System (INIS)

    Morthorst, P.E.

    2003-01-01

    Wind power is undergoing a rapid development nationally as well as globally and in a number of countries covers an increasing part of the power supply. At the same time an ongoing liberalization of power markets is taking place and to an increasing extent the owners of wind power plants will themselves have to be responsible for trading the power at the spot market and financially handling the balancing. In the western part of Denmark (Jutland/Funen area), wind-generated power from time to time covers almost 100% of total power consumption. Therefore some examples are chosen from this area to analyse in more detail how well large amounts of wind power in the short-term are handled at the power spot market. It turns out that there is a tendency that more wind power in the system in the short run leads to relatively lower spot prices, while less wind power implies relatively higher spot prices, although, with the exception of December 2002, in general no strong relationship is found. A stronger relationship is found at the regulating market, where there is a fairly clear tendency that the more wind power produced, the higher is the need for down-regulation, and, correspondingly, the less wind power produced, the higher is the need for up-regulation. In general for the Jutland/Funen area the average cost of down-regulation is calculated as 1 2 c euros/kWh regulated for 2002, while the cost of up-regulation amounts to 0 7 c euros/kWh regulated.

  6. Problems of gas marketing, particularly with respect to Swiss conditions

    Energy Technology Data Exchange (ETDEWEB)

    1981-07-01

    Rising gas prices have required a change in Switzerland's marketing strategy to a greater emphasis on the residential, commercial, and service sectors. A Swiss committee on energy in 1978 reported on three different scenarios for Swiss energy development. Excluding district heating and cogeneration use, natural gas consumption, though modest by world standards, grew 13.3% in 1979 to reach 7848 GWhr, or 4.2% of the total energy consumption. The Swiss gas industry association in 1979 began an information campaign to send out a series of six letters about gas.

    2012-03-01

    To review research literature and available information on the extent and impacts of marketing, current policy response and the interests engaged in the policy debate in order to inform recommendations for policy change on alcohol marketing. Relevant literature, including systematic reviews and publicly available information (websites and participant observation) is reviewed and synthesized. Alcohol marketing has expanded markedly in the past 50 years and, while there remains uncertainty about the impact across the population, there is now clear evidence of its impact on the consumption of young people. Few countries have effective policy in place restricting alcohol marketing, and there is a lack of an international response to alcohol marketing which crosses national boundaries. The protection of alcohol marketing has been a major focus for vested interest groups and this has affected governmental response at national and international levels. There has been a lack of non-governmental organization engagement. The policy response to tobacco marketing provides a clear contrast to that of alcohol marketing policy and provides a model for alcohol marketing policy. The global exposure of young people to alcohol marketing requires an urgent policy response. The Framework Convention on Tobacco Control provides an appropriate model for global governance to control alcohol marketing. There are extant examples of national level legislation achieving comprehensive bans with France's Loi Evin providing a feasible model. Resources from philanthropic organizations to allow non-governmental organization engagement are urgently required, as is engagement by the governmental sector independent of commercial influence. © 2012 The Author, Addiction © 2012 Society for the Study of Addiction.

    Li, Guoqiang; Gu, Xinhua; Wu, Jie

    2015-06-01

    This article presents a trade based theory of casino taxation along with empirical evidence found from Macao as a typical tourism resort. We prove that there is a unique optimum gaming tax in a particular market for casino gambling, argue that any change in this tax is engendered by external demand shifts, and suggest that the economic rent from gambling legalization should be shared through such optimal tax between the public and private sectors. Our work also studies the tradeoff between economic benefits and social costs arising from casino tourism, and provides some policy recommendations for the sustainable development of gaming-led economies. The theoretical arguments in this article turn out to be consistent with empirical observations on Macao realities over the recent decade.

    Full Text Available Althougt at first sight the crisis appears as a disturbance of the regular course of economic, social and organizational, this is a necessary step that turns old structures and relations to some superior functional. Under these conditions, hawever, it is absolutely necessary that the situation be properly evaluated by an analysis of developments and labour market structures and be taken right decision for the purposes of proper management of existing and potential recovery so far underused resources: people, values and strategies. The impact of the economic crisis on labour markets displays significant variation from one country to another. Employment rates and unemployment rates will be compared between European countries and for different groups of workers. Some countries have succeeded in keeping employment levels up and unemployment levels down through recourse to employmentpreservation and employment-creation measures combined with an expansion of active labour market policies. Moreover, certain labour market groups or categories have been particularly hard hit by the crisis. These include men, temporary workers, youth and migrant workers. In the EU Member States, crossing the crisis period was marked by changes in the sense orientation flexibleworking time and conservation work, a strategy that ensures rapid and reversible adaptation to the needs ofproduction entities present.

    Berk, Istemi [Koeln Univ. (Germany). Energiewirtschaftliches Inst.; Aydogan, Berna [Izmir Univ. of Economics (Turkey). Dept. of International Trade and Finance

    2012-09-15

    The purpose of this study is to investigate the impacts of crude oil price variations on the Turkish stock market returns. We have employed vector autoregression (V AR) model using daily observations of Brent crude oil prices and Istanbul Stock Exchange National Index (ISE- 1 00) returns for the period between January 2, 1990 and November 1, 2011. We have also tested the relationship between oil prices and stock market returns under global liquidity conditions by incorporating a liquidity proxy variable, Chicago Board of Exchange's (CBOE) S and P 500 market volatility index (VIX), into the model. Variance decomposition test results suggest little empirical evidence that crude oil price shocks have been rationally evaluated in the Turkish stock market. Rather, it was global liquidity conditions that were found to account for the greatest amount of variation in stock market returns.

    2005-01-01

    When examining the healthcare industry, the need for continuing education in internal functions (i.e., HR management) has been documented. However, equally important to success in the healthcare industry are external functions such as marketing. In an expansion of research on internally focused functions, we report findings from an exploratory study designed to examine the perceptions of executives about managerial skill needs in the externally focused area of marketing. Specifically, we examine eight key tasks in marketing and ask executives to rate the level of knowledge required for each and then to assess current, or actual, levels of knowledge in the field. Findings suggest that pricing strategy, product strategy, and segmentation and targeting were the tasks that require the most knowledge for healthcare marketers, and that they do, in fact, perceive various gaps in all of the areas examined. Implications and suggestions for future research are provided.

  1. Simulation of current pricing-tendencies in the German electricity market for private consumption

    International Nuclear Information System (INIS)

    Mueller, Moritz; Sensfuss, Frank; Wietschel, Martin

    2007-01-01

    The German electricity market for private consumption is characterized by increasing prices and low participation of the consumers. This prompts us to investigate the interdependencies between the customers' engagement in the market and the suppliers' pricing strategies. Based on an analysis of the German retail market, an agent-based simulation model is developed. Whereas the behaviour of private customers is calibrated on field data, the suppliers learn to maximize profits with a feedback-learning heuristic. The simulation results show a tendency of rising prices, which are created without the assumption of tacit collusion among suppliers. We conclude that in Germany the current market pressure of private customers may not be a sufficient incentive for suppliers to lower electricity prices. (author)

  3. Consequences of the Budget Deficit in the Current Crisis in Romania. Implications on the Labor Market

    Directory of Open Access Journals (Sweden)

    Gabriela MOLĂNESCU

    2011-02-01

    Full Text Available In the current economic activity conditions, in which the need of financial resources is usually higher than the existing funds, the elaborations of budgets at any level is one of the primary issues, particularly as regards the principle of budgetary balance. Approaches regarding sizing budgets deficits, means of financing and particularly sizing public debt get a series of touches of precise nature for different economies. Actual economic, financial, social and administrative conditions put up a series of problems which impose an extremely serious approach of the potential adverse impact by sizing of budget deficits and public debt over the real possibilities of noninflationary financing. In Romania, in the highly complex framework in which the economic activity takes place, in the attempt to show the place held by the budget deficit, a special role is assigned to determine the share of public financial deficit in the consolidated budget revenue and expenditure. Currently, knowledge and concern for reducing the budget deficit are still of great importance, especially as Romania is facing great difficulties in economic development. Amid deepening structural crisis phenomena, increasing budget deficits financed over a non-inflationary limits comes as an additional factor that contributes to imbalances of the economy. In addition, where budgetary expenditures are targeted to satisfy, primary, the redistribution function and to state subsidies, because of the lack of a real multiplier coefficient, the state budget deficit worsens. Influences such as introducing economic disturbance in the mechanisms which cause them to increase budget deficits can be summarized and grouped into two broad categories: economic influences and psychological influences. Regarding economic influences, we can say that they act strongly and strictly determined by how meanings used to cover budget deficit. The modalities used are subject to an analysis by direct or indirect

    To characterize indoor air quality at the markets in Hong Kong, three non-air-conditioned and two air-conditioned markets were selected for this study. The indoor air pollutants measured included PM 10 (particulate matters with aerodynamic diameter less than 10 μm), total bacteria count (TBC), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO 2 ) and sulfur dioxide (SO 2 ). The indoor and outdoor concentrations of these target air pollutants at these markets were measured and compared. The effects of air conditioning, temperature/relative humidity variation and different stalls on the indoor air quality were also investigated. The results indicated that all of the average indoor concentrations of PM 10 , TBC, CO and NO 2 at the markets were below the Hong Kong Indoor Air Quality Objectives (HKIAQO) standards with a few exceptions for PM 10 and TBC. The elevated PM 10 concentrations at Hung Hom, Ngau Tau Kok and Wan Chai markets were probably due to the air filtration of outdoor airborne particulates emitted from vehicular exhaust, whereas high concentrations of airborne bacteria at Sai Ying Pun and Tin Shing markets were linked to the use of air conditioning. Correlation analysis demonstrated that indoor bacteria concentrations were correlated with temperature and relative humidity. The operation of air conditioning did not significantly reduce the levels of air pollutants at the markets. However, the higher indoor/outdoor ratios demonstrated that the operation of air conditioning had influence on the levels of bacteria at the markets. It was found that average PM 10 concentration at poultry stalls was higher than the HKIAQO standard of 180 μg/m 3 , and was over two times that measured at vegetable, fish and meat stalls. Furthermore, the concentration of airborne bacteria at the poultry stalls was as high as 1031 CFU/m 3 , which was above the HKIAQO standard of 1000 CFU/m 3 . The bacteria levels at other three stalls were all below the HKIAQO standard

    Full Text Available As a consequence of the recent financial crisis, the adequacy of different Value-at-Risk (VaR methodologies was heavily questioned. Current practice in VaR assessment relies on modeling the whole distribution of returns. As an alternative, in this paper we model tail behavior of returns, and thus VaR, using conditional Extreme Value Theory (EVT, which combines EVT and GARCH methodology. Moreover, we examine the performance of conditional EVT with the daily returns of seven stock market indices, of which six are from Southeastern Europe (BelexLine, BET, BUX, CROBEX, SBITOP, SOFIX from the period of September 2004 - April 2013, and one from USA market (Standard&Poors 500 Index from the period January 1998 - April 2013. Backtesting of historical daily returns proves that conditional EVT model gives good predictions for all indices and for all confidence levels.

    Objectives To take inventory of the current state of affairs of Market Access Launch Excellence in the life sciences industry. To identify key gaps and challenges for Market Access (MA) and discuss how they can be addressed. To generate a baseline for benchmarking MA launch excellence. Methodology An online survey was conducted with pharmaceutical executives primarily working in MA, marketing, or general management. The survey aimed to evaluate MA excellence prerequisites across the product life cycle (rated by importance and level of implementation) and to describe MA activity models in the respective companies. Composite scores were calculated from respondents’ ratings and answers. Results Implementation levels of MA excellence prerequisites generally lagged behind their perceived importance. Item importance and the respective level of implementation correlated well, which can be interpreted as proof of the validity of the questionnaire. The following areas were shown to be particularly underimplemented: 1) early integration of MA and health economic considerations in research and development decision making, 2) developing true partnerships with payers, including the development of services ‘beyond the pill’, and 3) consideration of human resource and talent management. The concept of importance-adjusted implementation levels as a hybrid parameter was introduced and shown to be a viable tool for benchmarking purposes. More than 70% of respondents indicated that their companies will invest broadly in MA in terms of capital and headcount within the next 3 years. Conclusions MA (launch) excellence needs to be further developed in order to close implementation gaps across the entire product life cycle. As MA is a comparatively young pharmaceutical discipline in a complex and dynamic environment, this effort will require strategic focus and dedication. The Market Access Launch Excellence Inventory benchmarking tool may help guide decision makers to prioritize

    1997-01-01

    Biomass, organic wastes, hydroelectric power, wind power and solar energy contribute to approximately 6% of the current energy demand in the European Union (EU). Goals are set by the EU to double this share in the energy production in the next decade. The EU Altener Programme aims to increase the use of renewables as source of energy, the trade in renewable energy products and related equipment and services, supporting a wide variety of projects, sector and market studies, events and technical standards. The Agricultural and Forestrial Biomass Network (AFB-Nett) promotes and stimulates, as part of the Altener Programme, the implementation and commercial exploitation of energy from biomass by the initiation of among other things business opportunities and information exchange. The AFB-Nett National Coordinator for the Netherlands, Novem, organised in this respect the title seminar. 85 participants from several European countries attended presentations covering the whole bio-energy chain: from information on biomass supply, through trade, logistics and pretreatment issues up to discussion on conversion technologies. It became clear to the audience that it is a necessary condition to take into account the total chain when developing projects in a specific field of this chain. However, non-technical aspects must be considered as well. Therefore, in developing business opportunities the challenge remains to connect all good project initiatives covering parts of the chain into a few 'whole-chain'-projects

  12. Post market surveillance in the german medical device sector - current state and future perspectives.

    Medical devices play a central role in the diagnosis and treatment of diseases but also bring the potential for adverse events, hazards or malfunction with serious consequences for patients and users. Medical device manufacturers are therefore required by law to monitor the performance of medical devices that have been approved by the competent authorities (post market surveillance). Conducting a nationwide online-survey in the German medical device sector in Q2/2014 in order to explore the current status of the use of post market instruments we obtained a total of 118 complete data sets, for a return rate of 36%. The survey included manufacturers of different sizes, producing medical devices of all risk classes. The post market instruments most frequently reported covered the fields of production monitoring and quality management as well as literature observation, regulatory vigilance systems, customer knowledge management and market observation while Post Market Clinical Follow-up and health services research were being used less for product monitoring. We found significant differences between the different risk classes of medical devices produced and the intensity of use of post market instruments. Differences between company size and the intensity of instruments used were hardly detected. Results may well contribute to the development of device monitoring which is a crucial element of the policy and regulatory system to identify device-related safety issues.

    2008-09-01

    The main task of the control over an electric power system (EPS) is to ensure reliable power supply at the least cost. In this case, requirements to the electric power quality, power supply reliability and cost limitations on the energy resources must be observed. The available power reserve in an EPS is the necessary condition to keep it in operation with maintenance of normal operating variables (frequency, node voltage, power flows via the transmission lines, etc.). The authors examine possibilities to create power reserves that could be offered for sale by the electric power producer. They consider a procedure of price formation for the power reserves and propose a relevant mathematical model for a united EPS, the initial data being the fuel-cost functions for individual systems, technological limitations on the active power generation and consumers' load. As the criterion of optimization the maximum profit for the producer is taken. The model is exemplified by a concentrated EPS. The computations have been performed using the MATLAB program.

    Using the dynamic conditional correlation multivariate generalized autoregressive conditional heteroskedasticity (DCC-MGARCH) model, we empirically examine the dynamic relationship between stock market returns (KOSPI200 returns) and implied volatility (VKOSPI), as well as their statistical mechanics, in the Korean market, a representative and leading emerging market. We consider four macroeconomic variables (exchange rates, risk-free rates, term spreads, and credit spreads) as potential determinants of the dynamic conditional correlation between returns and volatility. Of these macroeconomic variables, the change in exchange rates has a significant impact on the dynamic correlation between KOSPI200 returns and the VKOSPI, especially during the recent financial crisis. We also find that the risk-free rate has a marginal effect on this dynamic conditional relationship.

    Full Text Available Stingless bees (kelulut keeping is now a trend in Malaysia. However, since demand for the source of colony in log is increasing, the log price is rapidly increasing. But, there is no data reported on the economic viability of meliponiculture in the current market price. Thus, the objective of this study is to clarify the economic viability of investment in meliponiculture in the current market price by engineering economic perspective. Investment in meliponiculture was analysed using Equivalent Annual Uniform Cost (EAUC, Internal Rate of Return (IRR and Breakeven Analysis. A small start-up with 30 units of logs or hives was considered in the analysis. All raw data was acquainted from current Malaysian market price, but only revenue from honey was considered. It was found that EAUC indicated that the annual worth of the log system is 23% better than the hive system. However, IRR calculation indicated that both the log and the hive systems offer margin exceeding 55% which is a very good return in general investment. In addition, it was also found that the log system had breakeven after 8th month, whereas the hive was 13th month. Better economic value could be obtained if revenue from by-products are considered. Thus, it can be concluded that meliponiculture is still very economically viable in Malaysia market trend, and the hive systems could be a better choice if splitting colony, maintenance, safety and aesthetics points of view are considered.

  19. Evolution and current status of demand response (DR) in electricity markets: Insights from PJM and NYISO

    International Nuclear Information System (INIS)

    Walawalkar, Rahul; Fernands, Stephen; Thakur, Netra; Chevva, Konda Reddy

    2010-01-01

    In electricity markets, traditional demand side management programs are slowly getting replaced with demand response (DR) programs. These programs have evolved since the early pilot programs launched in late 1990s. With the changes in market rules the opportunities have generally increased for DR for participating in emergency, economic and ancillary service programs. In recent times, various regulators have suggested that DR can also be used as a solution to meet supply - demand fluctuations in scenarios with significant penetration of variable renewable sources in grid. This paper provides an overview of the evolution of the DR programs in PJM and NYISO markets as well as analyzes current opportunities. Although DR participation has grown, most of the current participation is in the reliability programs, which are designed to provide load curtailment during peak days. This suggests that there is a significant gap between perception of ability of DR to mitigate variability of renewables and reality of current participation. DR in future can be scaled to play a more dynamic role in electricity markets, but that would require changes both on technology as well as policy front. Advances in building technologies and energy storage combined with appropriate price signals can lead to enhanced DR participation. (author)

    Full Text Available According to the CAPM, risk is measured by the beta, and the relation between required expected return and beta is linear. This paper examines the conditional relationship between beta and return in the US stock market. The conditional covariances and variances used to estimate beta are modeled as an ARCH process. The beta return relationship is tested upon the sign of the excess market return. The implication of the sign of the excess market return follows Morelli (2011. This study shows the importance of recognizing the sign of the excess market return when testing the beta-return relationship. The approach also allows us to distinguish the size effect and the effect of economic cycles.

    Highlights: •A dynamic duopoly Bertrand model with bounded rationality and quadratic cost function. •In Chinese air-conditioning market the boundary equilibrium point is locally stable. •The Lyapunov dimension of the chaos attractor is 1.9585. •The adjustment speeds may cause a market structure to behave chaotically. •The chaotic behavior can be controlled by decreasing the degree of substitutability. -- Abstract: A dynamic duopoly Bertrand model with quadratic cost function which is closer to reality and different from previous researches is discussed. The model is applied into air-conditioning market where the boundary equilibrium point is locally stable. Numerical simulations illustrate that the stability of Nash equilibrium strongly depends on the speed of adjustment of bounded rational player. The adjustment speeds and the degree of substitutability may undermine the stability of the equilibrium and cause a market structure to behave chaotically. The Lyapunov dimension of the chaos attractor is 1.9585 under some conditions. The stabilization of the chaotic behavior can be obtained by reducing the degree of substitutability. The results have an important theoretical and practical significance to Chinese air-conditioning market

    Conditional marketing authorization (CMA) in the European Union (EU) is an early access pathway for medicines that show promising therapeutic effects, but for which comprehensive data are not available. Using a mixed quantitative-qualitative research design, we evaluated how CMA has been used in marketing authorization of oncology medicines in the period 2006 to 2013. We show that compared to full marketing authorization, CMA is granted based on less comprehensive data. However, this is accompanied by significantly longer assessment times and less consensus among regulators about marketing authorization. Moreover, development time from first-in-human testing to marketing authorization did not differ between full marketing authorization and CMA, but was significantly longer for CMA compared to accelerated approved products in the United States (US). Results indicate that CMA is not used by companies as a prospectively planned pathway to obtain early access, but as a "rescue option" when submitted data are not strong enough to justify full marketing authorization. © 2015, The American Society for Clinical Pharmacology and Therapeutics.

    2016-11-01

    A submersible particle image velocimetry (PIV) system was used to study the wake of a horizontal axis marine current turbine. The turbine was tested in a large tow tank facility at the United States Naval Academy. The turbine is a 1/25th scale model of the U.S. National Renewable Energy Laboratory's Reference Model 1 (RM1) tidal turbine. It is a two-bladed turbine measuring 0.8 m in diameter and featuring a NACA 63-618 airfoil cross section. Separate wind tunnel testing has shown the foil section used on the turbine to be Reynolds number independent with respect to lift at the experimental parameters of tow carriage speed (Utow = 1 . 68 m/s) and tip speed ratio (TSR = 7). The wake survey was conducted over an area extending 0.25D forward of the turbine tip path to 2.0D aft, and to a depth of 1.0D beneath the turbine output shaft in the streamwise plane. Each field of view was approximately 30 cm by 30 cm, and each overlapped the adjacent fields of view by 5 cm. The entire flow field was then reconstructed into a single field of investigation. Results include streamwise and vertical ensemble average velocity fields averaged over approximately 1,000 realizations, as well as higher-order statistics. Turbine tip vortex centers were identified and plotted showing increasing aperiodicity with wake age. keywords: horizontal axis marine current turbine, particle image velocimetry, towing tank, wake survey

    Full Text Available The present study attempts to capture conditional or time-varying co-movement and dynamic interactions between the US and BRIC (Brazil, Russia, India, and China equity markets across the sample period 2004 to 2014 by employing diverse econometric models. The sample period is further divided into three different sub-periods concerning the US financial crisis period, viz. pre-crisis, crisis, and post-crisis periods. The vector autoregression- dynamic conditional correlation-multivariate asymmetric generalized autoregressive conditional heteroskedastic [VAR-DCC-MVAGARCH (1.1] model and Toda-Yamamoto’s (1995 Granger causality tests are employed for the purpose of overall analysis in a multivariate framework. The results report the existence of time-varying co-movement between the US and BRIC equity markets, whereby co-movement between the US and Brazilian markets is found to be the highest, followed by the Russian, Indian, and Chinese equity markets. Dynamic interactions are also registered between the respective US/BRIC comovements during different sub-periods. The results have important implications for market participants and policymakers.

    2005-01-01

    A virtually complete description of the topology of stationary incompressible Euler flows and the magnetic field satisfying the magnetostatic equation is given by a theorem due to Arnol'd. We apply this theorem to describe the topology of stationary states of plasmas with significant fluid flow, obeying the Hall magnetohydrodynamics model equations. In the context of the integrability (nonchaotic topology) of the magnetic and velocity fields, we discuss the validity of conditions analogous to that of Greene and Johnson, which, in the case of magnetostatic equations, states that the line integral ∫dl/B is the same for each closed magnetic field line on a given magnetic surface. We also show how this property follows from the existence of a continuous volume-preserving symmetry of the magnetic field

    Pyroclastic density currents (PDCs) are ground-hugging mixtures of hot gas and rock that can reach temperatures > 800 oC and speeds of 200 m/s. These flows are capable of eroding and entraining the underlying bed material into the flow, which can strongly influence flow momentum, runout distance, and hazards associated with PDCs. However, the mechanism of erosion remains poorly constrained, with proposed mechanisms including under-pressure following the head of the fluidized current, force chain enhanced stresses at the bed, and discrete particle impacts and friction. The interactions between PDCs and the bed have been difficult to observe in the field, as their infrequent occurrence, opacity, and hostile environment make real-time measurement difficult. This study is aimed at obtaining a better understanding of the interactions between PDCs and the bed through a quantitative analysis of bed forces. Our experimental apparatus consists of a rotating cylindrical flume of radius 22 cm, within which gas-rich granular material flows along the interior of the cylinder as it rotates. By using a rotating cylinder, we are able to simulate long-duration flows, allowing us to observe impact forces at the bed over timescales comparable to the flow duration of natural PDCs. To measure the distribution and evolution of forces imparted by the flow on the bed, we constructed a cylindrical insert with a non-erodible bed in which we embedded force sensor arrays parallel and perpendicular to the direction of flow. To measure the forces felt by the particles in the flow, we added "smart particles" 25 to 50 mm in diameter to the flow. Each smart particle contains a three-axis accelerometer and a micro SD card enclosed in a spherical plastic casing, and possesses a density similar to that of the pumice in the experimental flow. Each smart particle also contains a three-axis magnetometer which permits its location to be tracked by means of a unique applied magnetic field. Ultimately

    The goal of this study was to build basic information related to the production and market of human vaccine products in Korea, which can be an important indicator to provide basic data in practical use. Statistical data were obtained from the Bank of Korea, Korea Health Industry Development Institute, Korea Pharmaceutical Traders Association, and Korea Pharmaceutical Manufacturers Association. Vaccines are the 10th ranked drugs in the classification of whole complete preparated drugs. The production output of vaccines in Korea was 392.2 billion KRW in 2011, comprising 2.83% of complete preparated drug production output (13 trillion 880.8 billion KRW) and 2.54% of medical-pharmaceutical product output (15 trillion 440.3 billion KRW). The market scale of vaccines in Korea was 710 billion KRW in 2011, with an annual average growth rate of 11% in the past 6 years, comprising 2% of vaccine market in the world. There was also a significant increase in essential vaccines and other preventive vaccines in a global scale. Vaccines have the potential of becoming an emerging attractive industry. Based on the current analysis about the production of vaccine products and market scale, further development of the vaccine industry is expected in Korea.

    Full Text Available Acute myeloid leukemia (AML is an aggressive, fast-growing cancer beginning inside bone marrow and spreading into the blood system, most often occurring in immature white blood cells. It has the lowest five-year survival rate among other types of leukemia and if left untreated, it can be fatal. Even though there have been significant improvements in the treatment of other related subtypes, AMLtargeted therapy development have been limited. The current market for AML drugs cannot fill the high unmet needs in terms of drug safety and efficacy, and the growing aging population presents increased opportunities for new drugs. Considering these driving forces, it is believed that promising opportunities exist for new entrants to capture value from underserved segments of the market. It is estimated that the market size for AML drugs in 2020 will reach US$1.67 billion with an average annual growth of nearly 23%. Therefore, it is highly recommended for pharmaceutical companies to invest in this area of drug development as soon as possible in order to maximize gains from their investments as novel therapeutics enter the AML market at a rapid pace.

    The current supply/demand outlook for natural gas in Canada is discussed, starting with a review of natural gas supply trends since the deregulation of the market in 1985/86. Market demand trends and expansion of export pipeline capacity are summarized to demonstrate how radically the North American gas marketing industry has changed in the last decade. As of January 1st 1993, Canada ranked eleventh in the world with respect to remaining natural gas reserves (96 Tft 3 ), which represents only 2% of global gas reserves. Canada ranks third in gas production (5 Tft 3 /y), behind the USA and former Soviet Union (19 and 29 Tft 3 /y, respectively). In western Canada, gas production rates have increased 75% since deregulation. Canadian domestic demand has grown 24% since 1985 to the 1993 level of 2.1 Tft 3 /y, while exports to the USA have grown 144% to 2.2 Tft 3 /y. The present environment requires a 'just in time' attitude towards developing new gas reserves and arranging transportation and storage. Long term gas marketing transacations are increasingly deliverability-based, firm delivery commitments which include harsh penalties for nonperformance. 7 figs

    This project assesses the agricultural, technical and economic possibilities for producing the planned quantity of energy crops in year 2015. The assessments in this project are based on two essential assumptions: 1) The total demand for straw and energy crops to meet the energy plans is added up, and the available amount of straw is used first and energy crops will be used for the remaining amount. 2) As long as the present economic conditions for set-aside prevails, it will only be the set-aside areas that will be available for energy crop production. Energy crops are not seen as economic competitive with other cash-crops on the reform areas.Three different scenarios for the agricultural crop production up to year 2015 are outlined; a reference scenario where the current development is extrapolated; an environment scenario in which a higher degree of environmental awareness is taken into account and a market scenario in which the economic competitiveness of agricultural production gains more focus.

    Granic, G.; Jelavic, B.

    2003-01-01

    The theme of the 12. Forum: Energy Day in Croatia is energy sector liberalisation and the new position of the consumers, changing rapidly and acquiring a completely new perspective. By means of market opening of various energy forms the consumer gains right to choose the energy supplier, quite a radical change in relation to the former, monopolistic relationship. This means that the consumer becomes the centre of attention, as has already been achieved at the mobile phone market. Within new market environment, the consumer becomes product buyer, buyer of the product in principle bearing market characteristics as any other product. However, energy markets reveal numerous peculiarities, distinguishing them from the markets of goods and services, as we have known them for centuries, which function according to well-known market conditions. While part of the energy sector will permanently remain a natural monopoly (transmission / transportation and distribution networks), the opening of the considered market requires information science development, which means it is necessary to apply advanced technology for e.g. measuring devices, etc. In view of such market circumstances it is essential to define the quality of the product including supply stability, voltage quality or agility in responding to customer complaints. On the other hand, these factors cannot be adjusted to each individual consumer-buyer at the moment or at least not ones. The position of the customers-buyers has been solved differently in various countries. The aim of this Forum is to put forward and explain experience and solutions connected to the new customer-buyer role in market circumstances. It is our wish that the participants discuss problems connected to the consumer-buyer position under the following aspects: Present status of market opening for various energy forms in the countries of the EU and in the transition countries; technical preconditions for energy market opening such as information

    2016-01-01

    Full Text Available Biological production of organic acids from conversion of biomass derivatives has received increased attention among scientists and engineers and in business because of the attractive properties such as renewability, sustainability, degradability, and versatility. The aim of the present review is to summarize recent research and development of short chain fatty acids production by anaerobic fermentation of nonfood biomass and to evaluate the status and outlook for a sustainable industrial production of such biochemicals. Volatile fatty acids (VFAs such as acetic acid, propionic acid, and butyric acid have many industrial applications and are currently of global economic interest. The focus is mainly on the utilization of pretreated lignocellulosic plant biomass as substrate (the carbohydrate route and development of the bacteria and processes that lead to a high and economically feasible production of VFA. The current and developing market for VFA is analyzed focusing on production, prices, and forecasts along with a presentation of the biotechnology companies operating in the market for sustainable biochemicals. Finally, perspectives on taking sustainable product of biochemicals from promise to market introduction are reviewed.

  2. Economic potential of demand response at household level—Are Central-European market conditions sufficient?

    Prüggler, Natalie

    2013-01-01

    The aim of this paper is to show the economic potential of demand response (DR) on household level at Central European market conditions. Thereby, required economic benefits for consumers' participation, the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed. The core of this paper builds a case-study applying spot market-oriented load shifting from the supplier's point of view by using Austrian electricity market data, household load profiles as well as a heat pump and e-car charging load profile. It is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level. Furthermore, upper cost limits for intelligent infrastructure in order to break-even are derived. Results suggest to take a critical look at European discussions on DR implementation on household level, showing that at Central European market conditions the potential for DR at household level is restricted to significant loads and hence, the applied load shifting strategy is only beneficial with application to heat pumps. In contrast, the frequently discussed shifting of conventional household devices' loads (such as washing machines) economically does not add up. - Highlights: • Calculation of economic potential of domestic DR at Central European market conditions. • Model and case-study of spot market-oriented load shifting from supplier's perspective. • Derivation of supplier's cost savings and upper cost limits for ICT infrastructure. • Results show economic potential of domestic DR to be restricted to significant loads. • Shifting of washing machines economically does not pay off in contrast to heat pumps

    The wood pellet use in the heating and electricity sector has recorded a steady growth in the last years. IEA bioenergy task 40 carried out an update of the situation on the national pellet markets in the most relevant pellet producing countries and the global development as well. Various country specific data is collected and compiled for more than 30 countries, containing updated information about regulatory framework, production, consumption, price trends, quality standards and trade aspects. The analysis confirmed the positive development in terms of production and consumption of wood pellets in almost all countries. In 2015 more than 26 Mt of wood pellets have been produced and consumed worldwide. Technologies and markets become more mature. Increased international pellet trade needs to be supported by adequate frame condition not only for commerce, but also with regard to sustainability issues.

    Hydrogen is expected to be an important energy carrier, especially in the frame of global warming problem solution. The purpose of this study is to examine the condition of market penetration of hydrogen technologies in reducing CO 2 emissions. A multi-time-period linear programming model (MARKAL, Market Allocation)) is used to explore technology options and cost for meeting the energy demands while reducing CO 2 emissions from energy systems. The results show that hydrogen technologies become economical when CO 2 emissions are stringently constrained. 9 figs., 2 refs

    We model the joint movements of daily returns on one-month futures for crude oil, heating oil and natural gas through the multivariate GARCH with dynamic conditional correlations and elliptical distributions introduced by Pelagatti and Rondena [Pelagatti, M.M., Rondena, S., 2007. 'Dynamic Conditional Correlation with Elliptical Distributions', unpublished manuscript. Universita di Milano - Bicocca, August]. Futures prices of crude and heating oil covary strongly. The conditional correlation between the futures prices of natural gas and crude oil has been rising over the last 5 years. However, this correlation has been low on average over two thirds of the sample, suggesting that future markets have no established tradition of pricing natural gas as a function of developments on oil markets.

    This handbook on biofuels provides a comprehensive overview of different types of biofuels, and the technical options that exist to market the biofuels volumes expected to be consumed in the EU Member States in 2020. The study concludes that by fully utilizing the current blending limits of biodiesel (FAME) in diesel (B7) and bioethanol in petrol (E10) up to 7.9% share of biofuels in the EU transport sector can be technically reached by 2020. Increasing use of advanced biofuels, particularly blending of fungible fuels into diesel (eg. HVO and BTL) and the use of higher ethanol blends in compatible vehicles (e.g. E20), can play an important role. Also, the increased use of biomethane (in particular bio-CNG) and higher blends of biodiesel (FAME) can contribute. However, it is essential for both governments and industry to decide within 1 or 2 years on the way ahead and take necessary actions covering both, the fuels and the vehicles, to ensure their effective and timely implementation. Even though a range of technical options exist, many of these require considerable time and effort to implement and reach their potential. Large scale implementation of the options beyond current blending limits requires new, targeted policy measures, in many cases complemented by new fuel and vehicle standards, adaptation of engines and fuel distribution, etc. Marketing policies for these vehicles, fuels and blends are also likely to become much more important than in the current situation. Each Member State may develop its own strategy tailored to its market and policy objectives, but the EU should play a crucial facilitating role in these developments.

  7. Short-Term Expectation Formation Versus Long-Term Equilibrium Conditions: The Danish Housing Market

    Directory of Open Access Journals (Sweden)

    Andreas Hetland

    2017-09-01

    Full Text Available The primary contribution of this paper is to establish that the long-swings behavior observed in the market price of Danish housing since the 1970s can be understood by studying the interplay between short-term expectation formation and long-run equilibrium conditions. We introduce an asset market model for housing based on uncertainty rather than risk, which under mild assumptions allows for other forms of forecasting behavior than rational expectations. We test the theory via an I(2 cointegrated VAR model and find that the long-run equilibrium for the housing price corresponds closely to the predictions from the theoretical framework. Additionally, we corroborate previous findings that housing markets are well characterized by short-term momentum forecasting behavior. Our conclusions have wider relevance, since housing prices play a role in the wider Danish economy, and other developed economies, through wealth effects.

  8. Balanced Current Control Strategy for Current Source Rectifier Stage of Indirect Matrix Converter under Unbalanced Grid Voltage Conditions

    Directory of Open Access Journals (Sweden)

    Yeongsu Bak

    2016-12-01

    Full Text Available This paper proposes a balanced current control strategy for the current source rectifier (CSR stage of an indirect matrix converter (IMC under unbalanced grid voltage conditions. If the three-phase grid connected to the voltage source inverter (VSI of the IMC has unbalanced voltage conditions, it affects the currents of the CSR stage and VSI stage, and the currents are distorted. Above all, the distorted currents of the CSR stage cause instability in the overall system, which can affect the life span of the system. Therefore, in this paper, a control strategy for balanced currents in the CSR stage is proposed. To achieve balanced currents in the CSR stage, the VSI stage should receive DC power without ripple components from the CSR stage. This is implemented by controlling the currents in the VSI stage. Therefore, the proposed control strategy decouples the positive and negative phase-sequence components existing in the unbalanced voltages and currents of the VSI stage. Using the proposed control strategy under unbalanced grid voltage conditions, the stability and life span of the overall system can be improved. The effectiveness of the proposed control strategy is verified by simulation and experimental results.

    Full Text Available The study attempts to capture conditional variance of Indian banking sector’s stock market returns across the years 2005 to 2015 by employing different GARCH based symmetric and asymmetric models. The results report existence of persistency as well as leverage effects in the banking sector return volatility. On an expected note, the global financial crisis increased conditional volatility in the Indian banking sector during the years 2007 to 2009; further evidenced from Markov regime switches. The exponential GARCH (EGARCH model is found to be the best fit model capturing time-varying variance in the banking sector. The results support strong implications for the market participants at the time of devising portfolio management strategies.

    2017-04-01

    Full Text Available This perspective paper reports the results of a collaborative survey of French research institutes concerned with environmental issues, which examined the potential for a market uptake of climate services for adaptation in France. The study is based on a review of existing reports on the market of climate services, and on interviews of 68 climate service providers and users in public and private organizations. Although the study does not allow to provide quantified estimations regarding the present and future size of the market, its results offer new perspectives with implications extending far beyond the sole case of France: first, while the market is still in its infancy, significant opportunities exist in sectors such as flooding risks, and, to a slightly lesser extent, hydro and nuclear energy and viticulture. In addition, the study identifies critical conditions for the uptake in climate services: (1 a coordinated delivery of data, information, expertise and training by public research institutes concerned with climate change and its impacts; (2 the inclusion of adaptation in the regulation and in public and private tenders. Finally, (3 uncertainties in climate projections appear as a major barrier to the uptake of climate services. However, ambitious greenhouse gas emission reduction as planned by the COP-21 Paris Agreement contribute to reducing this uncertainties by allowing users to select a subset of climate change projections, avoiding those for which adaptation is most problematic.

    Cornell, Portia Y; Grabowski, David C; Cohen, Marc; Shi, Xiaomei; Stevenson, David G

    2016-08-01

    A key feature of private long-term care insurance is that medical underwriters screen out would-be buyers who have health conditions that portend near-term physical or cognitive disability. We applied common underwriting criteria based on data from two long-term care insurers to a nationally representative sample of individuals in the target age range (50-71 years) for long-term care insurance. The screening criteria put upper bounds on the current proportion of Americans who could gain coverage in the individual market without changes to medical underwriting practice. Specifically, our simulations show that in the target age range, approximately 30 percent of those whose wealth meets minimum industry standards for suitability for long-term care insurance would have their application for such insurance rejected at the underwriting stage. Among the general population-without considering financial suitability-we estimated that 40 percent would have their applications rejected. The predicted rejection rates are substantially higher than the rejection rates of about 20-25 percent of applicants in the actual market. In evaluating reforms for long-term care financing and their potential to increase private insurance rates, as well as to reduce financial pressure on public safety-net programs, policy makers need to consider the role of underwriting in the market for long-term care insurance.

    This paper evaluates the economic impact of the introduction of customer-owned Thermal Storage Air-conditioning (TSA) systems, in an electricity market, from the viewpoint of the load service entity. We perform simulations on the condition that several thousand customers install TSA systems and shift peak demand in an electricity market by one percent. Our numerical results indicate that the purchase cost of the LSE was reduced through load management of customers with TSA systems. The introduction of TSA systems also reduced the volatility of market clearing price and reduced the whole-trade cost in an electricity market.

    2008-03-13

    Norwegian cancer patients frequently use Noni. The objective of this study was to find out whether the way noni is marketed in Norway and the health claims made about the product harmonize with current scientific knowledge of its benefits/adverse effects. An overview of medical research on noni was obtained from three databases. Web sites for private persons and for companies that sell noni in Norway were examined. Books, pamphlets etc. from a company specializing in selling information material about noni, were also examined. 48 scientific articles were included in the study, but none of these were clinical studies of humans. Several pharmacological effects of noni have been shown in vitro and in animal models (e.g., increased survival for animals with cancer). Information material describes noni as a health-promoting product that patients with most diseases will benefit from. Noni is to a great extent sold by multi-level marketing, but is also commonly sold by health food stores. There is no scientific basis for claiming that patients will benefit from using noni for any diseases. The way this product is sold has several worrying aspects.

    It is critical to have pediatric post-marketing safety systems that contain enough clinical and epidemiological detail to draw regulatory, public health, and clinical conclusions. The pediatric safety surveillance workshop (PSSW), coordinated by the Food and Drug Administration (FDA), identified these pediatric systems as of 2010. This manuscript aims to update the information from the PSSW and look critically at the systems currently in use. We reviewed North American pediatric post-marketing safety systems such as databases, networks, and research consortiums found in peer-reviewed journals and other online sources. We detail clinical examples from three systems that FDA used to assess pediatric medical product safety. Of the 59 systems reviewed for pediatric content, only nine were pediatric-focused and met the inclusion criteria. Brief descriptions are provided for these nine. The strengths and weaknesses of three systems (two of the nine pediatric-focused and one including both children and adults) are illustrated with clinical examples. Systems reviewed in this manuscript have strengths such as clinical detail, a large enough sample size to capture rare adverse events, and/or a patient denominator internal to the database. Few systems include all of these attributes. Pediatric drug safety would be better informed by utilizing multiple systems to take advantage of their individual characteristics.

    Full Text Available In the context of globalization and due to the accelerated progress made in information and communication technology, more and more companies offer their employees the option of telecommuting. For the past twenty years, telecommuting has been on an asceding trend, an incresing number of people embracing the ability to work from home, using a computer and internet connection to communicate for their jobs. The goal of the paper is to explain the overall notion of telecommuting and to analyze the current trends in the United States and European Union markets. Another objective is to assess the advantages and disadvantages of telecommuting and the important role played by this concept within the striving purpose of corporations to achieve their strategic targets. The study is based upon specialized literature reviews regarding the emergence of telecommuting and the role it plays in organizations. A comparative analysis was conducted by the authors on two regional markets, United States and the European Union, in order to assess the trend in telecommuting and the factors that influence it. The outcome of the research shows that although the benefits of telecommuting are numerous, it does not come without challenges, both being applicable for both the employer, as well as for the employee. The research results of this study can be used by organizations when considering to offer their employees flexible work opportunities which can positively influence the long term business performance.

    Full Text Available In this paper we have evaluated the relationship of the credit market to the agricultural sector. The weakness of appropriate resource allocation from the credit market has been emphasized. We paid attention both to the external environment of agriculture itself, as well as to the way it has been shaped as a result of the process of globalization. The effect was examined of the influence of particular macroeconomic indicators adjusted according to the range of the interest rate as a result of change in the price of agricultural products. The period of the research covered the years 1990-2010. A discussion was carried out to allow for the setting apart of factors that influenced conditions which shaped the cost of financial loans and credit. The character of dependencies or related factors were analysed. The different significance of individual accounts was shown.

    Decarbonising transport is proving to be one of today's major challenges for the global automotive industry due to many factors such as the increase in greenhouse gas and particulate emissions affecting not only the climate but also humans, the increase in pollution, rapid oil depletion, issues with energy security and dependency from foreign sources and population growth. For more than a century, our society has been dependent upon oil, and major breakthroughs in low- and ultra-low carbon technologies and vehicles are urgently required. This review paper highlights the current status of hybrid, battery and fuel cell electric vehicles from an electrochemical and market point of view. The review paper also discusses the advantages and disadvantages of using each technology in the automotive industry and the impact of these technologies on consumers.

    There is not enough marketing of dentistry; but there certainly is too much selling of poor quality service that is being passed off as dentistry. The marketing concept makes the patient and the patients' needs the ultimate criteria of marketing efforts. Myths and good practices for effective marketing that will promote oral health are described under the traditional four "Ps" categories of "product" (best dental care), "place" (availability), "promotion" (advertising and other forms of making patients aware of available services and how to use them), and "price" (the total cost to patients of receiving care).

    This paper examines the stock market s reaction to JetBlue s Initial Public Offering (1PO) and subsequent price movements of the stock. In particular, w e examine whether the euphoria surrounding JetBlue s IPO carried over to other firms in the sector by testing whether the shares of JetBlue s competitors showed a significant price reaction to JetBlue s IPO. JetBlue's IPO took place just a few months following September 11, 2001. These events resulted in dramatic changes in the airline industry and had significant implications on the economic gains of airlines. We examine JetBlue s accounting and stock performance and compare it to the relative performance of Southwest Airlines (SWA), a representative of the loa-cost carrier group. In addition, we compare both JetBlue's and SWA's financial condition and the relative performance of their stock to two mainline U S. carriers, Continental and Northwest. representatives of the conventional-cost carrier group. We analyze whether there are any performance differences among the low-cost carriers and between low-cost carriers and conventional-cost carriers. In particular, we examine whether low-cost carriers were able to sustain the economic impacts of 9/11 better than the conventional-cost carriers.

    The paper discusses specificities of the energy sector as a business system in the condition of liberalized energy market. The government influence the business system through the rate of economical stability and and possibility for prognosis, as well as through the direct influence of the field government institutions on the process of the development of the economical structures. The finance system influences the government ability to support and lead the industrial development. Two main system types are known: decentralized management (in countries with developed stock markets and a system for entrusting of activities on contract basis) and centralized (the success of the policy is connected with the success of the economical growth). Another aspect of the management in a business environment is the procedure of decision making for the firm policy formation and applying of a model for firm development. The transition to liberalized market means a significant limitation of the role of the government, which in the Bulgarian case should replace the state control system in real time and the state credit. Since the low amortization the electricity production has low cost price and possibility for generation of rehabilitation funds, i.e for extension of the service life on minimal cost. The funds can be used for improvement of the stability of the sector. For the purposes of the analysis made, system parameters are reviewed with regard of the market realities. The Balkan region is semi-closed energy system 40% of the electricity is imported from several countries: Bulgaria, Romania, Serbia and Albania. The prices are greatly influenced by the moment conditions of the electricity production and industry in the region. The policy should be oriented in two directions: expectations for interests in the privatization of electric energy companies and appropriate strategy for preservation of the market positions.

    The majority of current models of the reactive magnetron sputtering assume a uniform shape of the discharge current density and the same temperature near the target and the substrate. However, in the real experimental set-up, the presence of the magnetic field causes high density plasma to form in front of the cathode in the shape of a toroid. Consequently, the discharge current density is laterally non-uniform. In addition to this, the heating of the background gas by sputtered particles, which is usually referred to as the gas rarefaction, plays an important role. This paper presents an extended model of the reactive magnetron sputtering that assumes the non-uniform discharge current density and which accommodates the gas rarefaction effect. It is devoted mainly to the study of the behaviour of the reactive sputtering rather that to the prediction of the coating properties. Outputs of this model are compared with those that assume uniform discharge current density and uniform temperature profile in the deposition chamber. Particular attention is paid to the modelling of the radial variation of the target composition near transitions from the metallic to the compound mode and vice versa. A study of the target utilization in the metallic and compound mode is performed for two different discharge current density profiles corresponding to typical two pole and multipole magnetics available on the market now. Different shapes of the discharge current density were tested. Finally, hysteresis curves are plotted for various temperature conditions in the reactor.

    In the U.S., economic conditions are intertwined with labor market decisions, access to health care, health care utilization and health outcomes. The Veterans Affairs (VA) health care system has served as a safety net provider by supplying free or reduced cost care to qualifying veterans. This study examines whether local area labor market conditions, measured using county-level unemployment rates, influence whether veterans obtain health care from the VA. We used survey data from the Behavioral Risk Factor Surveillance System in years 2000, 2003 and 2004 to construct a random sample of 73,964 respondents self-identified as veterans. VA health service utilization was defined as whether veterans received all, some or no care from the VA. Hierarchical ordered logistic regression was used to address unobserved state and county random effects while adjusting for individual characteristics. Local area labor market conditions were defined as the average 12-month unemployment rate in veterans' county of residence. The mean unemployment rate for veterans receiving all, some and no care was 5.56%, 5.37% and 5.24%, respectively. After covariate adjustment, a one percentage point increase in the unemployment rate in a veteran's county of residence was associated with an increase in the probability of receiving all care (0.34%, p-value = 0.056) or some care (0.29%, p-value = 0.023) from the VA. Our findings suggest that the important role of the VA in providing health care services to veterans is magnified in locations with high unemployment.

    Full Text Available The implementation of modern banking activities involves the realization of investments. Investment is a complex discussion economic category, characterized by a number of features. The types and forms of investment are manifold and can be transformed with account of the state of the economy and the level of development of industrial relations. The faster growth of the financial sector in the economy has stipulated the development of financial investment. Banks as financial and lending institutions actively make financial investments in securities. Banks’ investment in securities pursues a number of purposes which determine the selection of securities for investment and their quality. The article identified the targets of bank investments in securities and their development trends under current conditions on the basis of the analysis of the actual data for 2010–2014. Negative revaluation and the actual decrease in the value of corporate securities of Russian issuers reduce their commercial appeal. Banks refuse to speculate on the stock market in favor of the securities that ensure liquidity. Banks’ investments aim to purchasing securities from the Lombard List of the Bank of Russia in order to obtain loans and participate in the repo transactions. Thus, during the analyzed period, banks’ investments in securities transformed from systemically important assets that generate substantial profit into the mechanism that provides liquidity. It should be noted that a significant part of investment resources of Russian banks services the debt obligations of Russia’s Government. The article also identified a trend of banks’ increasing investment in the participation portfolios of subsidiaries and associated joint stock companies. The official data of the Central Bank of the Russian Federation (Bank of Russia [15], and the Federal State Statistics Service [14] were used as the information base for the study

    Full Text Available The paper concerns the relevant problem to optimize the combine heat and power (CHP plants in the Russian wholesale power market conditions. Since 1975 the CHP plants specialists faced the problem of fuel rate or fuel cost reduction while ensuring the fixed level of heat and power production. The optimality criterion was the fuel rate or fuel cost which has to be minimized. Produced heat and power was paid by known tariff. Since the power market started in 2006 the power payment scheme has essentially changed: produced power is paid by market price. In such condition a new optimality criterion the paper offers is a profit which has to be maximized for the given time horizon. Depending on the optimization horizon the paper suggests four types of the problem urgency, namely: long-term, mid-term, short-term, and operative optimization. It clearly shows that the previous problem of fuel cost minimization is a special case of profit maximization problem. To bring the problem to the mixed-integer linear programming problem a new linear characteristic curves of steam and gas turbine are introduced. Error of linearization is 0.6%. The formal statement of the problem of short-term CHP plants optimization in the market conditions is offered. The problem was solved with IRM software (OpenLinkInternational for seven power plants of JSC “Quadra”: Dyagilevskaya CHP, Kurskaya CHP-1, Lipetskaya CHP-2, Orlovskaya CHP, Kurskaya CHP NWR, Tambovskaya CHP, and Smolenskaya CHP-2.The conducted computational experiment showed that a potential profit is between 1.7% and 4.7% of the fuel cost of different CHP plants and depends on the power plant operation conditions. The potential profit value is 2–3 times higher than analogous estimations, which were obtained solving fuel cost minimization problem. The perspectives of the work are formalization of mid-term and long-term CHP plants optimization problem and development of domestic software for the new problem

    Full Text Available The term “region” is defined. It is studied that in the conditions of modern market economy for an effective management of financial resources it is necessary providing the enterprise activities with optimal amount of these resources, their rational use, maximization of income and providing the appreciation of market enterprise value. In such conditions the issues of improvement of management of production processes, the effective use of financial, labor, and material resources become topical. The transition to the modern market economy caused the changes of all the economic system and, for the first, regional enterprises. The terms of managing the economy suffered transformations, which found an expression in the changes of ownership patterns, the terms of government control, and the tax system. The non-public sector of economy appeared as a result of reforms, modern banking system, markets of commodities, services, capital. It gives an opportunity for the reproduction on an expanded scale, the increase of enterprise profits, and the income of its proprietors. One is able to achieve this goal only under the optimal management of finances. In the modern conditions of managing the economy the control system is to be migrated to regions differing one to another in national, historical, geographical, economic and other peculiarities. A structural policy that must foresee the transition of state economy to a new resource-provided, hi-tech and economically safe model of operation is realized in Ukraine. Establishing in the country of free economic zones, where the favourable custom, currency-financial, tax and other conditions of economic activity are in force, is very promising. The territorial social-and-economic structure of Ukraine is based upon the principles of unity and integral state power, an appropriate balance of socio-economic development of separate territories taking into account historical and cultural traditions, demographic and

    Rossing uranium mine is the only operating uranium mine in the world where the uranium occurs in intrusive alaskite. In the past 10 years, uranium market regressed in the world, uranium production weakened, expenditures of capital for uranium exploration were insufficient. Uranium spot market price rapidly decreased from $111.8/kg U in late 1970's to $22.1/kg U in mid-1990's. Why can Rossing uranium mine mined with traditional underground and open pit operation can keep running even in low price conditions of uranium market? Augumenting research on the deposit, mineral and technology, decreasing production cost and improving selling strategy can not only maintain Rossing's uranium production at present, but also ensure sustainable development in the coming 15 years. Exploration of low-costed uranium deposits is very important. However, obvious economic benefits can be obtained, as Rossing uranium mine does, by augumenting geological-economical research on the known uranium deposits of hard-rock type and by using new techniques to improve the conventional techniques in the uranium mine development.

    Full Text Available The aim of the research was to study the correspondence of existing legislative and regulatory requirements of the pharmaceutical industry development, the analysis of the formation of the Ukrainian pharmaceutical market, the condition of drug assistance according to European requirements and recommendations of the WHO. For the study archival materials, publications in scientific journals, and mass media were used, laws and provisions regulating pharmaceutical activity were studied and a survey among citizens was conducted. Systematic and logical methods, analytical and comparative analysis were applied, and own researches were performed. For 22 years of Ukrainian statehood formation the following institutes were created: Pharmacological College, Pharmacopoeia Committee and State Service for Quality Control of Drugs which were transported to other institutes. Important laws were adopted: the Law of Ukraine «On Medicines», the Law of Ukraine «On small-scale privatization», the Law of Ukraine «On large-scale privatization» and others, which contributed to the formation and development of the pharmaceutical market. In comparison with 1990 the amount of drugstore chains increased two and a half times and in 2013 in the country already worked 15 566 drugstores, including 3 025 in villages. Specific peculiarity of pharmaceutical market formation in Ukraine was the creation of powerful own regional and all-Ukrainian drugstore chains, that is greatly different from such situation in EU countries, where the legislation allows to have only one or two drugstores. As the result of pharmaceutical market formation the drugs nomenclature increased eight times and now makes up more than 20 000 names, including 92.4 % generic drugs. According to publications, Ukraine lacks about 40 % of drug molecules needed for medical treatment, and 30 % of studied drugs are not proved. There is the problem of uncontrollable turnover and drugs consumption in Ukraine

    This report serves as discussion document for the workshop 'Technologies for fuel cells and hydrogen in road transport' in Paris, France, March 2009. The workshop is part of the Efonet (Energy Foresight Network, www.efonet.org ) program initiated by the European Commission. As a starting point, the status quo of fuel cell technology is analyzed from an innovation perspective, compared with the current vehicle deployment in demonstration projects worldwide. Then, cost reductions of fuel cell and drive train components that can be achieved as function over time are modelled in a learning curve approach. This provides a forecast on the expected vehicle cost by cumulative production, enabling discussion on the connection between necessary vehicle deployment and current demonstration projects, also in respect to project finance. Within the EU HyWays project, four scenarios have been developed to model the penetration rates for hydrogen vehicles in transport. All scenarios are determined by two influencing factors, policy support and level of technological learning. Depending on the scenario, it is assumed that mass production of vehicles starts either by 2013 (2016) with a group of 5 (4) first movers that achieve up to 90% plant utilization in different time frames. Given the bandwidth of scenario results, it is possible to redefine cost targets and provide recommendations for the necessary policy support. The report also provides an assessment of current hydrogen vehicle RD and D activities by different OEMs and gives an indication on the expected market entry strategies and time frame. To conclude, cost of conventional and hydrogen vehicles are compared on a euro/km level, testing several policy measures for their suitability to lower the expected high vehicle cost for the end-consumer.

  20. Combined heat and gamma-irradiation treatments for the control of strawberry diseases under market conditions

    The spoilage of strawberries under local market conditions was investigated. It was confirmed that the major losses are due to 'leak' disease caused by Rhizopus stolonifer (Ehr. ex Fr.) Lind. It was also established that further fruit losses in summer are due to anthracnose caused by the fungus Colletotrichum acutatum Simmonds. This is the first time that the latter pathogen has been isolated and identified and recognised as a problem on strawberries in South Africa. Studies with R. stolonifer in culture showed that 46 degrees Celsius for 20 min (the previous international standard heat treatment for fruit) was disappointing, while a treatment at 50 degrees Celsius for 10 min effectively inhibited spore germination. Irradiation studies with cultures of R. stolonifer and C. acutatum showed that a dose of 200 and 100 krad, respectively, resulted in excellent inhibition of spore germination. However, irradiating in nitrogen gas resulted in a tenfold reduction in the effectiveness of the irradiation treatments. The use of nitrogen during irradiation, therefore, cannot be considered, especially where an effective control of the fungal pathogens is desired. Investigations with different cultivars clearly demonstrated the synergistic effect on disease control obtained when combining heat and irradiation treatments. The combination treatment (moist heat at 50-52 degrees Celsius for 10 min plus 200 krad), besides effectively controlling both diseases in strawberries, did not adversely affect berry quality. In simulated transport tests it was shown that a minimal amount of berry softening did occur with this treatment, but this adverse effect was negligible compared with the beneficial effect obtained from disease control. In semi-commercial experiments it was shown that the combination heat and irradiation treatment effectively controlled spoilage diseases for a period of several days from picking, thus allowing sufficient time to market the fruit under local market

The target population consisted of informal sellers working in the Bazurto market; sample size consisted of 584 sellers. A check-list was used to describe their working conditions. A "health disorders" test and neurotoxic symptoms scale (Q16) were used to determine health status and the body mass index (BMI) for determining nutritional status. 583 sellers participated in the study, having an average age of 39 years (38-40 95 %CI). 87.8 % (512) of the participants were exposed to constant noise, 84.9 % (495) worked in places having high temperatures, 74.1 % (432) were exposed to dust, and 69.8 % (407) did not use personal protective equipment. They were working 10 hours a day on average. 71 % (414) suffered from physical exhaustion, 72.4 % (422) had headaches, 63.7 % (371) had back pain and 62.7 % (365) suffered from pains in their legs. The target population's physical environment was inadequate, they worked for too many hours and some workplaces were dangerous. The informal sellers' symptoms included back pain, headaches, leg pain, eye strain and physical fatigue.

  4. The role of energy planners in open-free market conditions

    The evolution of the demand for electricity and natural gas usually follows seasonal patterns. In Mediterranean areas, in summer, a sharp increase in electricity needs in residential and commercial buildings coincides with a marked decrease in natural gas consumption. Air-conditioning systems are an increasingly significant factor in peak electricity demand in premises of all economic areas, particularly residential and commercial but also industrial sectors. Efforts made in recent years regarding the development of low cost air-conditioning equipment have produced in turn an increasing number of shortages due to lack of capacity in the production-transmission-distribution chain. Recent examples in Barcelona (June 2003) or Mallorca (July 2003) are just a reference for an ever-increasing problem. In open-free market conditions, how can this situation be overcome? Energy suppliers adopt strategies of Demand Side Management (DSM) in order to reduce negative impact of load curves which are not 'flat enough'. However, negative impacts are mainly seen in terms of economic operation, ignoring other effects such as energy or environmental collateral effects. From our point of view, Integrated Resources Planning (IRP) is a more powerful tool to take into account all three effects: economic, energy and environmental. IRP cannot be carried out by single energy suppliers, only by an Energy Planner. Two specific technologies can help balance energy loads from excess power demand (peak shaving) and reduced gas consumption (valley filling) in summer: High Efficiency Cogeneration / Trigeneration; High Efficiency Gas-Based Air-Conditioning. Recent COM(2003)416 final Directive 'on the promotion of cogeneration based on a useful heat demand in the internal energy market' (Brussels, July 23, 2003) can be adopted as a confirmation of the above issues.

    Full Text Available It has been more than 50 years since the idea to construct the bridge of Sunda Strait was inspirited by Prof. Sedyatmo. This issued is very important due to accelerate the economic growth between Sumatera Island and Java Island which is known as the densest population in the Indonesia. However, until today the bridge is still not construct yet because the high budget and the lack of technical data are still being problems. One of the most important data is current condition along the Sunda Strait. Unfortunately, no one has been clearly studied about current condition along Sunda Strait. Therefore, the information about current condition would be completed to fulfil the lack of data and information. The RV Geomarine I, as a research vessel conducted the survey in October 2012 that one of the objectives is to get the impression about the current condition around the bridge plan. Attaching echo sounder of bathy 1500 to get the depth profile and applied the RD Instrument ADCP Mobile Workhorse Monitor 300 kHz to collect the real current data and analyze the current using numerical model by Mike 21 were carried out to describe the condition of the current around the bridge proposed. In addition, the detail flexible mesh of hydrodynamic model is applied along bridge plan to analyse the current condition that caused by seafloor morphology. Based on the ADCP data it would be seen that the highest velocity record of the current occurs at October 18th 2012 at line 19 with the value 2.63 m/sec. Nevertheless, the numerical model shown the highest current velocity occurs around the northwest of Sangiang Island where the speed attains more than 4.59 m/sec.

    Superconducting magnets are energized through helium vapour-cooled cryogenic current leads operating at high ratios of current to mass flow. The high current operation where lead temperature, runaway, and eventual burn-up are likely to occur is investigated. A simple criterion for estimating the burn-up operation conditions (current, mass flow) for a given lead geometry (cross-sectional area, length, heat exchanger area) is presented. This article stresses the role played by the available heat exchanger area in avoiding burn-up at high ratios of current to mass flow. (author)

    1995-01-01

    During the past year, announcements regarding new methanol capacity have been too numerous to mention. Current producers are looking to increase capacity by debottlenecking or by adding additional capacity. Methanol consumers have announced plans to build new methanol plants or re-open older plants that had been shut down. While these new announcements would certainly seem adequate to supply any new demand that may be coming on-line, still other companies without prior methanol producing experience are looking to invest in new plants. This is not a situation occurring just in the US. All over the world new methanol capacity is being discussed. However, the topic of this paper involves only the US methanol market. If all the new capacity that has been announced does come on-line in the next two to three years, the methanol industry could be in for some very lean times. The demand picture for methanol looks to be strong with a healthy growth rate forecast. However, a growth in demand like that of the past three years should not be expected. Most of that growth came from the dramatic increases in MTBE capacity since the CAAA were announced

    Hoffman, David H; Rosenkrantz, Andrew B

    2018-03-24

    The purpose of the study is to characterize current practice patterns of abdominal radiologists based on work descriptions within job postings on numerous national radiology specialty websites. Job postings for either "abdominal" or "body" radiologists were searched weekly on five society websites (SAR, SCBT-MR, ARRS, ACR, RSNA) over a 1-year period. Postings were reviewed for various characteristics. Nine hundred and sixteen total ads for 341 unique abdominal radiologist positions were reviewed (34.6% academic, 64.2% private practice, 1.2% other). Postings occurred most commonly in March (12.3%) and least commonly in November (4.8%). States with most positions were Florida (27), California (26), and New York (24). Of postings delineating expectations of specific abdominal modalities, 67.4% mentioned MRI, 58.5% ultrasound, 41.1% fluoroscopy, 14.3% PET, and 54.0% interventions. Additional non-abdominal expectations included general radiology (28.7%), breast imaging (21.1%), and general nuclear medicine (9.7%). Additional skills included prostate MRI (7.0%), OBGYN ultrasound (5.0%), and CT colonoscopy (2.6%). 79.2% required an abdominal imaging fellowship (specifically a body MRI fellowship in 4.1%). By using job postings for abdominal radiologists, we have taken a practical approach to characterizing the current status of this subspecialty, reflecting recent job expectations and requirements. The large majority of positions required a body fellowship, and the positions commonly entailed a variety of skills beyond non-invasive diagnostic abdominal imaging. Of note, expectations of considerable minorities of positions included abdominal interventions, general radiology, and breast imaging. These insights may guide the development of abdominal radiology fellowships and mini-fellowships, as well as assist radiologists entering or returning to the job market.

  18. Research on the induction motor current signature for centrifugal pump at cavitation condition

    2015-11-01

    Full Text Available Cavitation is a major undesirable phenomenon for centrifugal pump because it can cause hydraulic performance deterioration, pump damage by pitting and material erosion, and structural vibration and noise. Cavitation can appear within the entire range of the operating conditions; therefore, it must be prevented by all means. Sensorless monitoring technology based on motor current signature analysis is non-intrusive and economic for monitoring motor-driven equipment. Thus, this technology is suitable for centrifugal pump systems. The motor current signature for centrifugal pump load at the cavitation condition is the basis of this technology. However, systematic research is lacking on sensorless monitoring technology based on motor current signature. As a result, the tentative exploration for motor current signature at cavitation load was conducted in this study. The results show that the stator current is still a sinusoidal alternating current strictly to the law of sine. Moreover, the root mean square of the current fluctuates because of different flow regimes in the cavitation progress and decreases because vapor density is smaller than water density when cavitation is fully formed. For the stator current spectrum, the noise level, noise distribution, rotation speed, and vane pass frequency components show features in the cavitation process. These indicator indexes change according to the stage of cavitation development. Thus, the motor current signature analysis is found to be a feasible and cost-effective method for the stages of cavitation condition.

    Full Text Available This work investigates the ability of the conditional CAPM to explain anomalous returns related to momentum, size and book-to-market effects using Lewellen and Nagel’s (2006 methodology in the Brazilian stock market. To this end we studied a sample of Bovespa’s stocks in a monthly basis from July 1995 to June 2008. The results indicate that only the book-to-market effect presents statistical significance. The conditional model, tested from time series of 12 months, also showed no significant gains in relation to the unconditional form. However, there are evidences that betas do vary over time, suggesting that the sample size on beta calculations may influence portfolio choices, i.e., the evidence of variation in betas over time means that analysis based on the CAPM should be cautious when using unconditional models.

    Full Text Available In Slovakian forestry the main source of finance is the wood sale. The main aim of this paper is to evaluate the assortments supply structure (quality management, prices development for the coniferous sawlogs and to set the future prediction of this development in new global market conditions, which are affected mainly by the global climate changes. Price changes were analysed for the period of the years from 2000 to March 2016 for the spruce and fir sawlogs. Data about the volume supply of raw-wood assortments in Slovakia for years 2005-2014 were collected from “Green Reports“ published by the Ministry of Agriculture and Rural Development of the Slovak Republic. From the influence factors in the studied period, the biggest impact was assigned to the global economic crisis. The prediction captures the further decline of prices of raw-wood assortments. In the second half of the year 2016 the price of sawlogs decreased by € 4 per 1 m3. Local impacts, the structure of wood processors and specific trade area in Slovakia affected substantially the structure of assortments on Market. There is also some space for a better evaluation of harvested wood.

  2. Peculiarities on voltage - current characteristics of HTS tapes at overloading conditions cooled by liquid nitrogen

    2008-01-01

    Electro - technical devices are considered as the most prospective use for high temperature superconductors. For such devices the overload currents due to faults in grids are the operational reality. In these cases the fault currents may forcibly go to superconductors being sometimes dozens times more than the critical currents of HTS. Overloads are the working modes for fault current limiters also. To understand the behavior of HTS devices at overloads it is important to study voltage-current characteristics (VCC) of basic HTS tapes in real cooling conditions. The knowledge of VCC permits to model and to simulate properly HTS devices behavior at overloads. We performed the study of VCC of several HTS tapes at currents several times more than their critical ones. Both, 1-G and 2-G tapes were tested. There were found peculiarities or 'spikes' on VCC at rising currents that vanished at decaying currents. It was shown that such peculiarities are determined by the change of cooling conditions from the convective heat exchange to the nucleate boiling. Nucleate boiling activation and development times were determined. Their dependencies on heat release were measured. The data obtained can be used in simulation of heating of real superconducting devices at overload conditions

    2006-03-01

    Full Text Available This article examines existing techniques and proposes its own for analyzing the attractiveness of international commodity markets in light of the globalization of world economic processes. Taking into account the supranational nature of the world economic environment when examining categories in the attractiveness of international commodity markets, the author introduces a multilevel system of indicators: market attractiveness at the mega-level – global level; market attractiveness at the macro-level national level; market attractiveness at the mezo-level – level of an individual sector. The attractiveness of international commodity markets is considered to be the degree of conformity between market environment factors and the mega-, macro- and mezo-levels of the economic interests of enterprises concerning the entry into and strategies for their activity on the international commodity markets in the short-, medium- and long-term. The author designs a stage-by-stage technique for strategically analyzing the attractiveness of international commodity markets in order to frame efficient market strategies of enterprises. Relying on the proposed techniques, she rates the integrated indicators of market accessibility and the possibility of realizing the economic interests of enterprises in target markets, bringing the index data into a matrix of «market accessibility – opportunity for realizing the economic interests of enterprises.» The analysis of a country’s position in the matrix makes it possible to frame efficient market strategies for enterprises.

    This study aims to investigate the crude oil volatility using a two components autoregressive conditional heteroscedasticity (ARCH) model with the inclusion of abrupt jump feature. The model is able to capture abrupt jumps, news impact, clustering volatility, long persistence volatility and heavy-tailed distributed error which are commonly observed in the crude oil time series. For the empirical study, we have selected the WTI crude oil index from year 2000 to 2016. The results found that by including the multiple-abrupt jumps in ARCH model, there are significant improvements of estimation evaluations as compared with the standard ARCH models. The outcomes of this study can provide useful information for risk management and portfolio analysis in the crude oil markets.

    2001-06-01

    Full Text Available This paper investigates the effect of the exchange market interventions of the Bank of Korea on the exchange rate of Korean won vis-a-vis US dollar during the 1997 currency crisis. In particular, this paper tests the effects of spot and forward market interventions, using daily intervention data of the Bank of Korea. During the 1997 period, Korea faced two series of crisis in January-March and September-November. It turns out that the spot market intervention was effective in stabilizing the spot market exchange rate at least during the first crisis period. In contrast, there seemed no effect of the forward market intervention. Forward market intervention was rather destabilizing through forward exchange rate during the second crisis period. This implies that even though the forward and sterilized spot market interventions are equivalent in their effect on exchange rate, these two instruments can widely diverge from each other under the circumstances of exchange rate volatility and speculation.

    In this paper, a new reference current computation method suitable for shunt active power filter control under distorted voltage conditions is proposed. The active power filter control is based on the use of self-tuning filters (STF) for the reference current generation and on a modulated hysteresis current controller. This active filter is intended for harmonic compensation of a diode rectifier feeding a RL load under distorted voltage conditions. The study of the active filter control is divided in two parts. The first one deals with the harmonic isolator which generates the harmonic reference currents and is experimentally implemented in a DS1104 card of a DSPACE prototyping system. The second part focuses on the generation of the switching pattern of the inverter by using a modulated hysteresis current controller, implemented in an analogue card. The use of STF instead of classical extraction filters allows extracting directly the voltage and current fundamental components in the {alpha}-{beta} axis without phase locked loop (PLL). The performances are good even under distorted voltage conditions. First, the effectiveness of the new proposed method is mathematically studied and verified by computer simulation. Then, experimental results are presented using a DSPACE system associated with the analogue current controller for a real shunt active power filter. (author)

    2015-01-01

    Full Text Available Asset pricing is a widely explored theme in the financial literature. Nevertheless, the phenomenon of value premium is still controversial, since although easily detected in developed and emerging markets, little is know about the economic forces that explain its existence. In this context, this article examines value premium in the Brazilian market and investigates the influence of the country risk variable as an additional risk factor for estimating conditional returns in this market not captured by value premium. For that, we employ a five-factor model, formulated by adding the country risk factor to the model of Carhart (1997. We apply the statistical procedure adopted by Fama & French (1993 to the period between 1994 and 2012, with data on nonfinancial companies listed on the BM&FBovespa. The results confirm the existence of value premium in the Brazilian market, and country risk and value premium together are significant factors to explain conditional returns.

    2006-12-01

    Health care reform proposals often rely on increased competition in health insurance markets to drive improved performance in health care costs, access, and quality. We examine a range of data issues related to the measures of health insurance competition used in empirical studies published from 1994-2004. The literature relies exclusively on market structure and penetration variables to measure competition. While these measures are correlated, the degree of correlation is modest, suggesting that choice of measure could influence empirical results. Moreover, certain measurement issues such as the lack of data on PPO enrollment, the treatment of small firms, and omitted market characteristics also could affect the conclusions in empirical studies. Importantly, other types of measures related to competition (e.g., the availability of information on price and outcomes, degree of entry barriers, etc.) are important from both a theoretical and policy perspective, but their impact on market outcomes has not been widely studied.

    Full Text Available Market crises are interpreted in much the same way. Hence action is also always of a similar type, regardless of the market crisis that may have occurred. It is a similar set of tools that are applied to all crises, and usually this has to do with managing the money supply, interest rates, and slapping on austerity measures. But this is a myopic view. Crises are never the same. Presented here is a holistic model that draws inspiration form the journey a seed makes in becoming a flower in more fully understanding the nature of the crisis we may be facing. Action will be different depending on what phase in the journey the economy is assessed at being. In this paper we look at market crises scanning four decades, from the Bear Market of the early 1970s to recent European Union Sovereign Debt Crises.

    Heavy Quark Effective Theory (HQET) computations of semi-leptonic decays, e.g. B{yields}{pi}l{nu}, require the knowledge of the parameters in the effective theory for all components of the heavy-light flavor currents. So far non-perturbative matching conditions have been employed only for the time component of the axial current. Here we perform a check of matching conditions for the time component of the vector current and the spatial component of the axial vector current up to one-loop order of perturbation theory and to lowest order of the 1/m-expansion. We find that the proposed observables have small higher order terms in the 1/m-series and are thus excellent candidates for a non-perturbative matching procedure.

  17. Neutron transport assembly calculation with non-zero net current boundary condition

    1993-02-01

    Fuel assembly calculation for the homogenized group constants is one of the most important parts in the reactor core analysis. The homogenized group constants of one a quarter assembly are usually generated for the nodal calculation of the reactor core. In the current nodal calculation, one or a quarter of the fuel assembly corresponds to a unit node. The homogenized group constant calculation for a fuel assembly proceeds through cell spectrum calculations, group condensation and cell homogenization calculations, two dimensional fuel assembly calculation, and then depletion calculations of fuel rods. To obtain the assembly wise homogenized group constants, the two dimensional transport calculation is usually performed. Most codes for the assembly wise homogenized group constants employ a zero net current boundary condition. CASMO-3 is such a code that is in wide use. The zero net current boundary condition is plausible and valid in an infinite reactor composed of the same kind of assemblies. However, the reactor is finite and the core is constructed by different kinds of assemblies. Hence, the assumption of the zero net current boundary condition is not valid in the actual reactor. The objective of this study is to develop a homogenization methodology that can treat any actual boundary condition, i.e. non-zero net current boundary condition. In order to treat the non-zero net current boundary condition, we modify CASMO-3. For the two-dimensional treatment in CASMO-3, a multigroup integral transport routine based on the method of transmission probability is used. The code performs assembly calculation with zero net current boundary condition. CASMO-3 is modified to consider the inhomogeneous source at the assembly boundary surface due to the non-zero net current. The modified version of CASMO-3 is called CASMO-3M. CASMO-3M is applied to several benchmark problems. In order to obtain the inhomogeneous source, the global calculation is performed. The local calculation

    This paper is an extension of the author's recent research in which only buck converters were analyzed. Similar analysis can be equally applied to other types of converters. In this paper, a unified model is proposed for buck, boost, and buck-boost converters under peak or average current mode control to predict the occurrence of subharmonic oscillation. Based on the unified model, the associated stability conditions are derived in closed forms. The same stability condition can be applied to ...

    . In these codes, the injection of positive- and negative-sequence current components becomes necessary for fulfilling, among others, the low-voltage ride-through requirements during balanced and unbalanced grid faults. However, the performance of classical dq current controllers, applied to power converters......, under unbalanced grid-voltage conditions is highly deficient, due to the unavoidable appearance of current oscillations. This paper analyzes the performance of the double synchronous reference frame controller and improves its structure by adding a decoupling network for estimating and compensating...

  20. Maximum power point tracking for PV systems under partial shading conditions using current sweeping

    International Nuclear Information System (INIS)

    Tsang, K.M.; Chan, W.L.

    2015-01-01

    Highlights: • A novel approach for tracking the maximum power point of photovoltaic systems. • Able to handle both the uniform insolation and partial shading conditions. • Maximum power point tracking based on current sweeping. - Abstract: Partial shading on photovoltaic (PV) arrays causes multiple peaks on the output power–voltage characteristic curve and local searching technique such as perturb and observe (P&O) method could easily fail in searching for the global maximum. Moreover, existing global searching techniques are still not very satisfactory in terms of speed and implementation complexity. In this paper, a fast global maximum power point (MPPT) tracking method which is using current sweeping for photovoltaic arrays under partial shading conditions is proposed. Unlike conventional approach, the proposed method is current based rather than voltage based. The initial maximum power point will be derived based on a current sweeping test and the maximum power point can be enhanced by a finer local search. The speed of the global search is mainly governed by the apparent time constant of the PV array and the generation of a fast current sweeping test. The fast current sweeping test can easily be realized by a DC/DC boost converter with a very fast current control loop. Experimental results are included to demonstrate the effectiveness of the proposed global searching scheme

  1. Uncertainties in the Value of Bill Savings from Behind-the-Meter, Residential Photovoltaic Systems: The Roles of Electricity Market Conditions, Retail Rate Design, and Net Metering

    Science.gov (United States)

    Darghouth, Naim Richard

    Net metering has become a widespread policy mechanism in the U.S. for supporting customer adoption of distributed photovoltaics (PV), allowing customers with PV systems to reduce their electric bills by offsetting their consumption with PV generation, independent of the timing of the generation relative to consumption. Although net metering is one of the principal drivers for the residential PV market in the U.S., the academic literature on this policy has been sparse and this dissertation contributes to this emerging body of literature. This dissertation explores the linkages between the availability of net metering, wholesale electricity market conditions, retail rates, and the residential bill savings from behind-the-meter PV systems. First, I examine the value of the bill savings that customers receive under net metering and alternatives to net metering, and the associated role of retail rate design, based on current rates and a sample of approximately two hundred residential customers of California's two largest electric utilities. I find that the bill savings per kWh of PV electricity generated varies greatly, largely attributable to the increasing block structure of the California utilities' residential retail rates. I also find that net metering provides significantly greater bill savings than alternative compensation mechanisms based on avoided costs. However, retail electricity rates may shift as wholesale electricity market conditions change. I then investigate a potential change in market conditions -- increased solar PV penetrations -- on wholesale prices in the short-term based on the merit-order effect. This demonstrates the potential price effects of changes in market conditions, but also points to a number of methodological shortcomings of this method, motivating my usage of a long-term capacity investment and economic dispatch model to examine wholesale price effects of various wholesale market scenarios in the subsequent analysis.

    1991-04-01

    This study sought to determine attitudes toward nutrition, nutrition marketing practices, the relationship between attitudes toward nutrition and nutrition marketing practices, and nutrition training practices in restaurants. A written questionnaire was mailed to 200 research and development (R & D) directors in restaurant companies included in Restaurants & Institutions' list of top 400 foodservice organizations ranked by sales. Seventy (35%) responded. Most R & D directors did not think they were responsible for improving the health of their consumers. A positive relationship existed between attitudes toward nutrition and nutrition marketing practices (P = .013). Forty-four reported that they marketed nutrition and planned to add nutritious menu items in the future. Forty-six reported that nutritious meal options represented 0 to 10% of total sales. Nutrition information was provided to consumers by 27 restaurant companies but such information often had to be requested. The American Heart Association was a popular source of nutrition and menu-planning information. Twelve companies employed a registered dietitian, and 14 used registered dietitians as consultants. Nutrition-related training for restaurant employees was limited. These findings indicate that dietitians have opportunities to market their skills in developing nutritious menu items and providing staff training. Also, dietitians should encourage consumers (especially those with special dietary needs) to let restaurant managers know their menu and nutrition information needs.

    2013-01-01

    We study the time evolution of the ASEP on a finite lattice with L sites and open boundaries, conditioned on an atypically low current up to a finite time t. By an exact computation, we show that for a one-parameter family of boundary densities and a special value of the conditioned current, an initial product measure with an antishock at site k evolves into a convex combination of such antishocks at sites k′. The weights p(k′, t|k, 0) are shown to be the transition probabilities of simple biased random walk with reflecting boundaries. We compute explicitly these transition rates. Our result implies that the antishock remains microscopically stable under the locally conditioned dynamics. (paper)

  13. Distributed generation in European electricity markets. Current challenges and future opportunities

    Ropenus, S. (Technical Univ. of Denmark, Risoe National Lab. for Sustainable Energy. Systems Analysis Div., Roskilde (Denmark))

    This Ph.D. thesis studies the role of distributed generation in European electricity markets. It focuses primarily on the interactions of economics and policy with the aim of contributing to the understanding of how distributed generation is embedded in the present regulatory and market framework, which barriers exist, and which role it may possibly play in the future. To capture the interdisciplinarity of the topic, a combination of qualitative and quantitative methods is applied. Subsequent to the identification of barriers, this thesis turns to the microeconomic perspective on the interplay of vertical structure, regulation and distributed generation. This is done through the application of quantitative methods in the form of partial equilibrium models focusing on the effects induced by the vertical structure of the network operator, either a combined operator or a distribution system operator, in a market with small distributed producers. In areas where the promotion of renewable energy sources and combined heat and power has induced a substantial increase in distributed generation, new challenges in system integration arise. In particular, high levels of generation from intermittent energy sources, such as wind, add to the complexity of network operation and control, which can hardly be tackled with the present 'fit and forget' approach. The conclusion is that distributed generation has great potential to enhance competitiveness, sustainability and security of supply in European electricity markets. A prerequisite is the removal of market and regulatory barriers, taking the interdependencies of vertical structure, support mechanisms and network access into account. In the future, higher penetration levels of distributed generation necessitate changes in the power system and the adoption of new technologies, where hydrogen production by grid connected electrolysis constitutes one example.

  15. Operating modes of high-Tc composite superconductors and thermal runaway conditions under current charging

    International Nuclear Information System (INIS)

    Romanovskii, V R; Watanabe, K

    2006-01-01

    The operating thermal and electric modes of a high-T c superconducting composite in partially and fully penetrated states induced by the charging current are investigated. They were studied under conditions in which the current charging rate, the volume fraction of the superconductor in a composite or the temperature of the cooling bath were changed. The transient behaviour of the voltage-current dependence, which is characteristic during stable and unstable increases in electric field inside the composite under a continuous current charging, is discussed. Simulations were done using zero- and one-dimensional steady and unsteady thermoelectric models with a power equation describing the virgin voltage-current characteristic of a superconductor. It is found that some thermoelectric trends underlie the shape of the voltage-current characteristic of the high-T c superconducting composite. These have to be considered during experiments in which the critical or quench currents are defined. First, in the initial stage of the fully penetrated regime (in the low voltage range), the electric field distribution does not have a uniform character. These states depend on the volume fraction of the superconductor and the current charging rate: the higher these quantities, the higher the heterogeneity of the electric field. Second, during the stable over-critical regime (in the high voltage range) occurring in complete penetration modes, the evolution of the electric field may depend on the relevant temperature increase of a composite according to the corresponding increase in its temperature-dependent heat capacity. Consequently, the shape of the voltage-current characteristic of a composite high-T c superconductor during continuous current charging, both before and after thermal runaway, has only a positive slope. Moreover, it is proved that the growth of the fully penetrated part of the voltage-current characteristic becomes less intensive when the current charging rate or the

    Fifteen currently marketed intravaginal protection products (11 types of tampon and four menstrual cups) were tested by the modified tampon sac method to determine their effect on Staphylococcus aureus growth and toxic shock toxin 1 (TSST-1) production. Most tampons reduced S. aureus growth and TSST-1 production, with differences based on brand and composition, and S. aureus growth was higher in de-structured than in unaltered tampons. We observed higher S. aureus growth and toxin production in menstrual cups than in tampons, potentially due to the additional air introduced to the bag by cups, with differences based on cup composition and size. Importance Menstrual toxic shock syndrome is a rare but severe disease. It occurs in healthy women vaginally colonized by Staphylococcus aureus producing toxic shock syndrome toxin 1 using intravaginal protection such as tampons or menstrual cups. Intravaginal protection induces TSS production by collecting catamenial products which act as a growth medium for S. aureus Previous studies have evaluated the impact of tampon composition on S. aureus producing toxic shock syndrome toxin 1, but they are not recent and did not include menstrual cups. This study demonstrates that highly reproducible results for S. aureus growth and TSST-1 production can be obtained using a simple protocol that reproduces the physiological conditions of tampon and cup usage as closely as possible, providing recommendations for tampon or cup use to both manufacturers and consumers. Notably, our results do not show that menstrual cups are safer than tampons and suggest that they require similar precautions. Copyright © 2018 American Society for Microbiology.

The raison d’etre for this type of market is that although supply and demand are balanced on a day-ahead basis, actual demand is impossible to forecast with complete accuracy. Thus on the day...... of operation actual demand and planned supply never match precisely. The system operator must then procure so-called balancing power in the intra-day market to maintain the physical balance of the system at all times.

    Full Text Available Planning and distribution economy with state ownership of agricultural enterprises, which were dominant in the early 90s the economy of the country, was unable to provide normal functioning of the agricultural land use in the conditions of transition to market relations. To switch to another economic system began a gradual process of transformation of agricultural enterprises. The result of this process was the change in the structure of agrarian enterprises due to privatization and raspaevaniya land, and appearance from small-scale farms to large agricultural enterprises. Today identified market actors (enterprises in agriculture: business companies, private enterprises, production cooperatives, farmers, public enterprises, other forms of management. The most common kind of private business are farms. They are one of the most promising and effective forms of management with high agriculture, appropriate level of production organization, prudent attitude to the land and best landscaping. However, today the formation of farming in Ukraine has not yet reached the level of development, which is observed in economically developed countries. The overall economic decline and inadequate legislation has forced farmers to rely on themselves. Notes the insufficient level of their competitiveness, making it impossible to provide the expanded reproduction, determines the risk of insolvency and, as a consequence, leads to bankruptcy. Farmers receive government support, but it is weak and temporary, which greatly impedes their development. Practical state support only a few farms that can affect the distribution of funds. Agricultural cooperation is one of the effective forms of management, which aims to unite the producers in the direction of increase of efficiency of use of their resource potential. However, today there are a number of unresolved problems that hinder the effective development of agricultural cooperatives. Since 2000 years, the initiative in

    What are the strategies of success in the global biosimilar market? In general, originators have short-term options available, such as patent litigation, but should focus on sustainable long-term strategies such as development of biobetters or incorporating biosimilars as complements to existing products. For new entrants to the market, the learning curve will be steep and only biosimilars developed to compete with the best-selling biologics will be successful over the next decade. The attitudes of physicians, patients and payers will be crucial to the reception future biosimilars will receive and it will be essential that other players contribute to this debate.

    We investigate the impact of both parallel and transverse boundary conditions on the current and charge transport in open field line systems using the TOKAM2D code, which solves a minimal model for interchange turbulence. Various limit test cases are discussed and analyzed. In the parallel direction, the sheath conductivity is found to play an essential role in the stabilization of large-scale potential structures, leading to the formation of transport channel or transport barrier respectively for an insulating end wall or a wall with an enhanced sheath conductivity. On another hand, the addition of transverse boundary conditions intrinsically changes the transport characteristics, influencing both radial profiles and probability density functions. It underlines that in some cases a detailed description of the plasma-wall interaction process is required to get a proper description of the current loop pattern that determines electrostatic turbulent transport.

    Understanding the life-cycle private cost (LCPC) of the hybrid electric vehicle (HEV) is important for market feasibility analysis. An HEV LCPC model was established to evaluate HEV market prospects in China compared with traditional internal combustion engine vehicles (ICEV). The Kluger HV, a full-hybrid HEV sports utility vehicle (SUV), aimed at the Chinese market, was simulated as the 2010 model's technology details were well publicized. The LCPC of the Kluger HV was roughly the same (about 1.06 times) as that of its comparable ICEV (Highlander SUV). This aligns with other compact and midsize HEV cars (e.g., Toyota Prius, Honda Civic and Toyota Camry HEV) in China. With oil prices predicted to rise in the long-term, the advantage of HEVs energy saving will partly compensate the high manufacturing costs associated with their additional motor/battery components. Besides supporting technology development, enabling policy should be implemented to introduce HEV technology into taxi fleets and business cars. This technology's cost-competitiveness, compared with traditional ICEVs, is advantageous for these higher mileage vehicles. - Highlights: ► A model is set up to evaluate the life-cycle private cost of HEVs. ► Life-cycle private costs of HEVs are higher than conventional cars in China. ► HEVs become competitive when the oil price rises

  11. DC Link Current Estimation in Wind-Double Feed Induction Generator Power Conditioning System

    2010-12-01

    Full Text Available In this paper the implementation of the DC link current estimator in power conditioning system of the variable speed wind turbine is shown. The wind turbine is connected to double feed induction generator (DFIG. The variable electrical energy parameters delivered by DFIG are fitted with the electrical grid parameters through back-to-back power converter. The bidirectional AC-AC power converter covers a wide speed range from subsynchronous to supersynchronous speeds. The modern control of back-to-back power converter involves power balance concept, therefore its load power should be known in any instant. By using the power balance control, the DC link voltage variation at the load changes can be reduced. In this paper the load power is estimated from the dc link, indirectly, through a second order DC link current estimator. The load current estimator is based on the DC link voltage and on the dc link input current of the rotor side converter. This method presents certain advantages instead of using measured method, which requires a low pass filter: no time delay, the feedforward current component has no ripple, no additional hardware, and more fast control response. Through the numerical simulation the performances of the proposed DC link output current estimator scheme are demonstrated.

  12. Current Needs for the Experimental Investigation of the CHF Phenomenon Relevant to LWR Core Conditions

    2009-01-01

    The current achievements and needs toward the investigation, understanding and mechanistic prediction of the Critical Heat Flux (CHF) event, under PWR and BWR core conditions, are addressed in this paper. It is shown that, even when using advanced 3-D CFD simulation tools, the current approach to CHF mechanistic modeling has serious limitations. This is mainly due to the lack of information regarding the relevant two-phase flow pattern(s) (in particular near the heated wall) and associated mechanisms (at the meso and micro-scale) leading to the CHF event. Areas of current experimental needs are identified in order to address these shortcomings. In addition, the use of 1-D and 3-D numerical tools to mechanistically predict the CHF is discussed. It is shown that 3-D two-phase CFD codes may not be superior to 1-D codes without proper consideration of relevant constitutive relations. (author)

    The National Electrostatics Corporation's (NEC) Toroidal Volume Ion Source (TORVIS) source is known for exceptionally high proton currents with minimal service downtime as compared to traditional sputter sources. It has been possible to obtain over 150μA of proton current from the source, with over 70μA on the target stage. However, beam fluxes above ∼1×10 17 /m2-s may have many undesirable effects, especially for insulators. This may include high temperature gradients at the surface, sputtering, surface discharge, cracking or even disintegration of the sample. A series of experiments were conducted to examine the role of high current fluxes in a suite of ceramics and insulating materials. Results will show the optimal proton irradiation conditions and target mounting strategies needed to minimize unwanted macro-scale damage, while developing a procedure for conducting preliminary radiation experiments.

    Physics-based simulation results can vary widely depending on the applied boundary conditions. As a first step toward assessing the effect of boundary conditions on ring current simulations, we analyze the uncertainty of cross-polar cap potentials (CPCP) on electric field boundary conditions applied to the Rice Convection Model-Equilibrium (RCM-E). The empirical Weimer model of CPCP is chosen as the reference model and Defense Meteorological Satellite Program CPCP measurements as the reference data. Using temporal correlations from a statistical analysis of the "errors" between the reference model and data, we construct a Monte Carlo CPCP discrete time series model that can be generalized to other model boundary conditions. RCM-E simulations using electric field boundary conditions from the reference model and from 20 randomly generated Monte Carlo discrete time series of CPCP are performed for two large storms. During the 10 August 2000 storm main phase, the proton density at 10 RE at midnight was observed to be low (Dst index is bounded by the simulated Dst values. In contrast, the simulated Dst values during the recovery phases of the 10 August 2000 and 31 August 2005 storms tend to underestimate systematically the observed late Dst recovery. This suggests a need to improve the accuracy of particle loss calculations in the RCM-E model. Application of this technique can aid modelers to make efficient choices on either investing more effort on improving specification of boundary conditions or on improving descriptions of physical processes.

    Detecting replacement conditions of railway point machines is important to simultaneously satisfy the budget-limit and train-safety requirements. In this study, we consider classification of the subtle differences in the aging effect-using electric current shape analysis-for the purpose of replacement condition detection of railway point machines. After analyzing the shapes of after-replacement data and then labeling the shapes of each before-replacement data, we can derive the criteria that can handle the subtle differences between "does-not-need-to-be-replaced" and "needs-to-be-replaced" shapes. On the basis of the experimental results with in-field replacement data, we confirmed that the proposed method could detect the replacement conditions with acceptable accuracy, as well as provide visual interpretability of the criteria used for the time-series classification.

    This study explores the dynamic interaction between stock market returns and changes in nominal exchange rates. Many financial variables are known to exhibit fat tails and autoregressive variance structure. It is well-known that unconditional covariance and correlation coefficients also vary significantly over time and multivariate generalized autoregressive model (MGARCH) is able to capture the time-varying variance-covariance matrix for stock market returns and changes in exchange rates. The model is applied to daily Euro-Dollar exchange rates and two stock market indexes from the US economy: Dow-Jones Industrial Average Index and S&P500 Index. The news impact surfaces are also drawn based on the model estimates to see the effects of idiosyncratic shocks in respective markets.

    To assess the association of parental education, childhood living conditions and adversities with daily smoking in early adulthood and to analyse the effect of the respondent's own education, main economic activity, and current family structure on these associations. The study is based on a representative two-stage cluster sample (N = 1894, participation rate 79%) of young adults aged 18-29, in 2000, in Finland. The outcome measure is daily smoking. Parental smoking and the respondent's own education had the strongest effects on daily smoking. If both parents of the respondent were smokers, then the respondent was most likely to be a smoker too (for men OR (odds ratio) = 3.01, for women OR = 2.41 after all adjustments). Young adults in the lowest educational category had a much higher risk of daily smoking than those in the highest category (OR = 5.88 for women, 4.48 for men). For women parental divorce (OR = 2.31) and current family structure also determined daily smoking. Parental education had a strong gradient in daily smoking and the effect appeared to be mediated largely by the respondent's own educational level. Childhood living conditions are strong determinants of daily smoking. Much of their influence seems to be mediated through current living conditions, which are also determined by childhood conditions. Determinants of smoking behaviour are developed throughout the life course. The findings stress the importance of the respondent's education and parental smoking as determinants of smoking behaviour. Our results support the notion that intervention on smoking initiation and cessation should be considered throughout the life course. Parental involvement in fostering non-smoking would be important.

    The restructuring of retail gas services has followed a typical pattern for previously heavily regulated industries: large customers are initially given rights to purchase unbundled services from different entities, with the same rights dispersed over time to smaller customers. For about ten years now industrial customers in most states have been able to {open_quotes}play the market{close_quotes}. Since the passage of the Federal Energy Regulatory Commission (FERC) Order 636 in 1992, interest has centered on expanding service unbundling to small retail customers, including residential customers. Importantly, the Order prohibited pipelines from providing bundled sales service. This is not surprising - in the telecommunications industry, for example, the unbundling of wholesale services was a strong stimulant for developing competition in the local exchange market. The push for small-customer service unbundling has derived from the basic but politically attractive idea that all retail customers should directly benefit from competitive forces in the natural gas industry. When one looks at the movement of prices since 1985, it is easy to see that large retail customers have enjoyed more favorable prices than other retail customers. For example, over the period 1985 to 1994 gas prices to industrial customers and electric utilities fell around 23 percent and 36 percent, respectively. In comparison, gas prices to residential customers increased by around 5 percent while gas prices to commercial customers decreased slightly by about 1 percent. This report examines various aspects of unbundling to small retail gas customers, with special emphasis on residential customers.

    This report updates a baseline risk assessment for the 300 Area prepared in 1994. The update includes consideration of changes in contaminants of interest and in the environment that have occurred during the period of interim remedial action, i.e., 1996 to the present, as well as the sub-regions, for which no initial risk assessments have been conducted. In 1996, a record of decision (ROD) stipulated interim remedial action for groundwater affected by releases from 300 Area sources, as follows: (a) continued monitoring of groundwater that is contaminated above health-based levels to ensure that concentrations continue to decrease, and (b) institutional controls to ensure that groundwater use is restricted to prevent unacceptable exposure to groundwater contamination. In 2000, the groundwater beneath the two outlying sub-regions was added to the operable unit. In 2001, the first 5-year review of the ROD found that the interim remedy and remedial action objectives were still appropriate, although the review called for additional characterization activities. This report includes a current conditions baseline ecological and human health risk assessment using maximum concentrations in the environmental media of the 300-FF-5 Operable Unit and downstream conditions at the City of Richland, Washington. The scope for this assessment includes only current measured environmental concentrations and current use scenarios. Future environmental concentrations and future land uses are not considered in this assessment.

The main findings can be summarized as follows: (1 The primary (aggregate mode of adjustment to the crisis was a decline in employment. There are, however, considerable differences in adjustment patterns across economic activities. (2 During the crisis, jobs were lost in the, more dynamic, private sector, while the number of jobs in the public sector (entities in state ownership slightly increased. (3 Economic activities with comparatively larger shares of women in employment have experienced fewer employment cuts and the aggregate employment share of women rose during the crisis, especially in activities with a larger share of public sector workers.(4 There has been a declining share of younger workers during the crisis, justifying policy actions to facilitate their employment. (5 Employees with comparatively lower educational attainment face severe challenges in the labor market, which is a longer term trend, not specific to the crisis period. There are indications that this group of employees enjoys a higher level of protection in the public sector. (6 Analysis also shows a rising significance of more flexible forms of employment: increasing shares of fixed term employees (during the last two observed years, and of part time workers.

    Adverse socioeconomic conditions in childhood have been previously linked with high risk of various health conditions. However, the association with future physical function has been less studied. Hand grip strength and chair-rising time are objective measures of physical capability indicating current and future health outcomes. The aim of this study was to test the hypothesis that perceived socio-economic status in childhood is related to current measures of physical function, among Israeli participants of the Survey of Health, Ageing and Retirement in Europe project. The study included 2300 participants aged 50 years or older (mean age 68 ± 10; 56 % women). Generalized linear regression models were used to examine the associations of childhood wealth and number of books in residence with grip strength and time to complete five rises from a chair. Logistic regression models were used to assess the relationships between the early life conditions and the ability to perform the physical tests. Adjustment was made for current income or household wealth, and for demographic, anthropometric, health, and life-style measures. Being wealthy and having a large number of books at home in childhood was associated with a stronger hand grip and a better chair-rise test performance. These associations were more robust in women compared to men, and persisted after adjustment for potential covariates. In addition, childhood wealth and number of books were associated with lower risk of being unable to perform the tests. Thus, early-life programming may contribute to physical function indicators in mid- and late-life.

    The Energy management systems (EMS) on demand sides are expected as a method to enhance the capability of supply and demand balancing of a power system under the anticipated penetration of renewable energy generation such as Photovoltaics (PV). Elucidation of energy consumption structure in a building is one of important elements for realization of EMS and contributes to the extraction of potential energy saving. In this paper, we propose the estimation method of operating condition of household appliances using circuit current data on an electric distribution board. Circuit current data are broken down by their shape using a self-organization map method and aggregated by appliance based on customers' information of appliance possessed. Proposed method is verified using residential energy consumption measurement survey data.

    Coal and gas continue to play a significant role in the European power generation system, especially in Germany. According to the AG energy balances, the share of hard coal in German gross electricity generation in 2016 was 17.2% and natural gas 12.4%. In addition to the CO 2 price, the prices for steam coal and natural gas are a key factor in determining which gas or coal power station is in Merit Order and whether it comes to a fuel switch. Declining gas prices have been rising sharply since the middle of 2016, and the volatile prices for steam coal have been rising. This article discusses the developments and factors responsible for these developments, which could be expected in the near future, and the implications for the gas-coal spread in the electricity market.

    Full Text Available This article investigates the performative relationship among folklore, the market, and the state through an analysis of the politics of Bulgarian wedding music. In the socialist period wedding music was condemned by the state and excluded from the category folk but was adored by thousands of fans as a counter-cultural manifestation. In the post-socialist period wedding music achieved recognition in the West but declined in popularity in Bulgarian as fusion music's, such as chalga (folk/pop, arose and as musicians faced challenges vis-à-vis capitalism. As the state withdrew and became weaker private companies with profit-making agendas arose. Although it inspired chalga, wedding music began to be seen in contrast to it, as folk music. Recently, fatigue with chalga and nationalistic ideologies are revitalizing wedding music.

    Turbidity currents pose a hazard to seafloor infrastructure, deliver organic carbon and nutrients to deep-sea communities, and form economically important deposits. Thus, determining the tempo of turbidity current activity and whether different triggers result in different flow modes is important. Identification of specific triggers is challenging, however, because most studies of turbidity currents are based on their deposits. New direct monitoring of flows and environmental conditions provides the necessary temporal constraints to identify triggering mechanisms. The Coordinated Canyon Experiment (CCE) in Monterey Canyon, offshore California is the most ambitious attempt yet to measure turbidity flows and their triggers. The CCE provides precise constraint on flow timing, initiation, and potential triggers based on measurements at 7 different instrumented moorings and 2 metocean buoys. Fifteen turbidity flows were measured in 18 months; with recorded velocities >8 m/s and run-outs of up to 50 km. Presence of live estuarine foraminifera within moored sediment traps suggests that that flows originated in water depths of Turbidity currents are thought to be triggered by processes including earthquakes, river floods and storm waves. Here we analyse seismicity, local river discharge, internal tides, wave height, direction and period data. We identify no clear control of any of these individual variables on flow timing.

    Experimental results on the phase slip process in superconducting lead nanowires are presented under two different experimental conditions: constant applied current or constant voltage. Based on these experiments we established a simple model which gives us the condition of the appearance of phase...... slip centers in a quasi-one-dimensional wire. The competition between two relaxations times (relaxation time of the absolute value of the order parameter τ and relaxation time of the phase of the order parameter in the phase slip center τ) governs the phase slip process. Phase slips, as periodic...... oscillations in time of the order parameter, are only possible if the gradient of the phase grows faster than the value of the order parameter in the phase slip center, or equivalently if τ≤ τ....

    Climate change and growing population are expected to severely affect freshwater availability by the end of 21th century. Many river basins, especially in the Mediterranean region, are likely to become more prone to periods of reduced water supply, risking considerable impacts on the society, the environment, and the economy, thus emphasizing the need to rethink the way water resources are distributed, managed, and used at the regional and river basin scale. This paradigm shift will be essential to cope with the undergoing global change, characterized by growing water demands and by increasingly uncertain hydrologic regimes. Most of the literature traditionally focused on predicting the impacts of climate change on water resources, while our understanding of the human footprint on the hydrological cycle is limited. For example, changes in the operation of the Alpine hydropower reservoirs induced by socio-economic drivers (e.g., development of renewable energy) have been already observed over the last few years and have produced relevant impacts on multiple water uses due to the altered distribution of water volumes in time and space. Modeling human decisions as well as the links between society and environmental systems becomes key to develop reliable projections on the co-evolution of the coupled human-water systems and deliver robust adaptation strategies. This work contributes a preliminary model-based analysis of the behaviour of hydropower operators under changing energy market and climate conditions. The proposed approach is developed for the San Giacomo-Cancano reservoir system located in the Lake Como catchment. The identification of the current operating policy is supported by input variable selection methods to select the most relevant hydrological and market based drivers to explain the observed release time series. The identified model is then simulated under a set of future scenarios, accounting for both climate and socio-economic change (e

  3. A Model based Examination of Conditions for Ignition of Turbidity Currents on Slopes

    Turbidity currents form a major mechanism for the movement of sediment in the natural environment. Self-accelerating turbidity currents over continental slopes are of considerable scientific and engineering interest due to their role as agents for submarine sediment transportation from the shelf to the seabed. Such currents are called ignitive provided they eventually reach a catastrophic state as acceleration results in high sediment loads due to erosion of the sloping bed. A numerical model, which treats the fluid and the particles as two separate phases, is applied to investigate the effects of particle size, initial flow friction velocity and mild bed slope on the ignitive condition. Laboratory experimental data have been included as part of the analysis for qualitative comparison purposes. Ignition for the smallest of the three selected sizes (0.21mm) of medium sand typical of Florida beaches was found to depend on the initial conditions at the head of the slope as determined by the pressure gradient. Bed slope seemed to be of secondary importance. For the two sands with larger grain sizes (0.28mm and 0.35mm) the slope was found to play a more important role when compared to the initial pressure gradient. For a given pressure gradient, increasing the slope increased the likelihood of self-acceleration. It is concluded that in general ignition cannot be defined merely in terms of positive values of the velocity gradient and the sediment flux gradient along the slope. Depending on particle size the initial pressure gradient can also play a role. For the selected initial conditions (grain size, pressure gradient and bed slope), out of the 54 combinations tested, all except three satisfied the Knapp-Bagnold criterion for auto-suspension irrespective of whether the turbid current was ignitive or non-ignitive. In all 54 cases the current was found to erode the bed. Further use of the model will require accommodation of wider ranges of sediment size and bed density

  4. THE THEORY OF EFFICIENT MARKETS AND A MODEL OF RATIONAL INVESTOR – FROM CONDITIONS OF RISK TO TERMS OF CONFLICT

    Full Text Available The theoretical assumption about the informative effectiveness of financial markets is very important, although the discussion about its compatibility with the reality still re-mains open. The article summarises the key elements of the theory of efficient markets, paying particular attention to the adopted in this theory assumption about a rational inves-tor, which also appears in other models and theories related to the financial markets (such as capital asset pricing model CAPM or Markowitz Portfolio Theory. The views on the way and criteria for decision-making by a rational investor have changed over the centu-ries. Today, the dominant theory in this regard is the theory of expected utility. However, it characterizes the decision-making process under risk conditions, which are not the most common economic environment, particularly in an economy subjected to the process of globalisation. Thus, the problem of using the models of decision making under conditions of uncertainty, ignorance and terms of conflict in the efficient market theory and the theo-ry of expected utility is under consideration in the final part of the article.

    This paper is concerned with carbon price volatility and the underlying causes of large price movements in the European emissions trading market. Based on the application of a combined jump-GARCH model the behavior of EUA prices is characterized. The jump- GARCH model explains the unsteady carbon price movement well and, moreover, shows that between 40 and 60 percent of the carbon price variance are triggered by jumps. Information regarding EUA supply and news from international carbon markets are identified as important drivers of these price spikes. These results can lead regulators the way if smoother carbon prices are desired.

    Since 1991, there has been a series of reforms of the English National Health Service (NHS) entailing an increasing separation between the commissioners of services and a widening range of public and independent sector providers able to compete for contracts to provide services to NHS patients. We examine the extent to which local commissioners had adopted a market-oriented (transactional) model of commissioning of care for people with long term conditions several years into the latest period of market-oriented reform. The paper also considers the factors that may have inhibited or supported market-oriented behaviour, including the presence of conditions conducive to a health care quasi-market. We studied the commissioning of services for people with three long term conditions - diabetes, stroke and dementia - in three English primary care trust (PCT) areas over two years (2010-12). We took a broadly ethnographic approach to understanding the day-to-day practice of commissioning. Data were collected through interviews, observation of meetings and from documents. In contrast to a transactional, market-related approach organised around commissioner choice of provider and associated contracting, commissioning was largely relational, based on trust and collaboration with incumbent providers. There was limited sign of commissioners significantly challenging providers, changing providers, or decommissioning services.In none of the service areas were all the conditions for a well functioning quasi-market in health care in place. Choice of provider was generally absent or limited; information on demand and resource requirements was highly imperfect; motivations were complex; and transaction costs uncertain, but likely to be high. It was difficult to divide care into neat units for contracting purposes. As a result, it is scarcely surprising that commissioning practice in relation to all six commissioning developments was dominated by a relational approach. Our findings

  7. Bora-induced currents corresponding to different synoptic conditions above the Adriatic

    Full Text Available The Bora wind field is characterised by strong vorticity and divergence. Several numerical experiments, in which an oceanographic model was forced with northeasterly winds having climatological alongshore variability, were performed in order to study the influence of spatial variability in the bora wind field on the surface currents in the northern Adriatic. Numerical model results showed that during bora episodes with lower speeds and fast offshore decay surface currents along transect Rovinj - Po River are predominantly in the downwind direction. On the other hand, during bora episodes with strong intensity and slow offshore decay, a cyclonic gyre due to the pronounced bora alongshore variability is formed in the northernmost part of the Adriatic Sea and the studied transect is influenced by the counter currents. Moreover, bora having a high speed and a short offshore range produces the same effect in the eastern part of the Rovinj - Po River transect as low-speed bora characterised by slow offshore decay. Eulerian current measurements performed in the northern Adriatic during bora episodes characterised by different synoptic conditions supported the numerical model findings. Surface currents during the bora episode of 8-11 February 1984 were directed downwind, whereas during the episode of 12-19 February 1984 they were directed upwind. The first episode was characterised by a deep bora layer with cyclonic activity over the western Mediterranean and Genoa Bay, whereas the second one was accompanied by temperature inversion and a southwesterly tropospheric wind above a shallow bora layer. According to the hydraulic theory developed by Smith (1985, an observed descent of isentropes during the second bora episode led to the stronger acceleration in the bora layer and its larger offshore extent. Different offshore bora decays during studied events were confirmed by a comparison of the wind data originating from the meteorological stations

    E-waste is one of the fastest-growing waste streams in Iran, owing to an increase in consumption of electrical and electronic equipment. Nevertheless, as is the case in some other countries, E-waste management has not received sufficient attention. For the successful implementation of any waste management plan (including an E-waste management plan), the availability of sufficient and accurate information on the quantities and composition of the waste generated and on current management conditions is a fundamental prerequisite. At present, in Iran, there is no available and accurate information that describes the characteristics and generation rate of E-waste or the actual practice of management and handling of the waste. For this initial study, eight electronic products were selected for the determination of their E-waste generation rate in the country, and two cities, Tehran and Tabriz, were selected for assessment of the current condition of E-waste management. The study found that the amount of E-waste generation in the country for the eight selected electronic items alone was 115,286, 112,914 and 115,151 metric tons in 2008, 2009 and 2010, respectively. Of the types of electronic items included in the study, televisions, with an average of 42.42%, and PCs, with an average of 32.66% accounted for the greatest proportions of the total mass of E-waste generated during 2008-2010. Currently, despite the fact that primary legislation for E-waste management (as part of general waste legislation) exists in Iran, this primary legislation has not yet been implemented. In practical terms, there is no definite policy or plan for the allocation of funds to prepare suitable equipment and facilities for the management and recycling of E-waste at the end of the products' useful life. Proposed improvements in current conditions are identified, first by considering other countries' experiences and then suggesting specific practical policies, rules, and regulations that should be

    The gas pipeline networks in Sichuan and Chongqing (Sichuan-Chongqing) region have formed a fully-fledged gas pipeline transportation system in China, which supports and promotes the rapid development of gas market in Sichuan-Chongqing region. In the circumstances of further developed market-oriented economy, it is necessary to carry out further the pipeline system reform in the areas of investment/financing system, operation system and pricing system to lay a solid foundation for improving future gas production and marketing capability and adapting itself to the national gas system reform, and to achieve the objectives of multiparty participated pipeline construction, improved pipeline transportation efficiency and fair and rational pipeline transportation prices. In this article, main thinking on reform in the three areas and major deployment are addressed, and corresponding measures on developing shared pipeline economy, providing financial support to pipeline construction, setting up independent regulatory agency to enhance the industrial supervision for gas pipeline transportation, and promoting the construction of regional gas trade market are recommended.

  17. Unbundling the retail gas market: Current activities and guidance for serving residential and small customers

    The restructuring of retail gas services has followed a typical pattern for previously heavily regulated industries: large customers are initially given rights to purchase unbundled services from different entities, with the same rights dispersed over time to smaller customers. For about ten years now industrial customers in most states have been able to open-quotes play the marketclose quotes. Since the passage of the Federal Energy Regulatory Commission (FERC) Order 636 in 1992, interest has centered on expanding service unbundling to small retail customers, including residential customers. Importantly, the Order prohibited pipelines from providing bundled sales service. This is not surprising - in the telecommunications industry, for example, the unbundling of wholesale services was a strong stimulant for developing competition in the local exchange market. The push for small-customer service unbundling has derived from the basic but politically attractive idea that all retail customers should directly benefit from competitive forces in the natural gas industry. When one looks at the movement of prices since 1985, it is easy to see that large retail customers have enjoyed more favorable prices than other retail customers. For example, over the period 1985 to 1994 gas prices to industrial customers and electric utilities fell around 23 percent and 36 percent, respectively. In comparison, gas prices to residential customers increased by around 5 percent while gas prices to commercial customers decreased slightly by about 1 percent. This report examines various aspects of unbundling to small retail gas customers, with special emphasis on residential customers

    During the 2007-2008 heparin crisis it was found that the United States Pharmacopeia (USP) testing monograph for heparin sodium or low molecular weight heparins did not detect the presence of the contaminant, oversulfated chondroitin sulfate (OSCS). In response to this concern, new tests and specifications were developed by the Food and Drug Administration (FDA) and USP and put in place to detect not only the contaminant OSCS, but also to improve assurance of quality and purity of these drug products. The USP monographs for the low molecular weight heparins (LMWHs) approved for use in the United States (dalteparin, tinzaparin and enoxaparin) are also undergoing revision to include many of the same tests used for heparin sodium, including; one-dimensional (1D) 500 MHz (1)H NMR, SAX-HPLC, percent galactosamine in total hexosamine and anticoagulation time assays with purified Factor IIa or Factor Xa. These tests represent orthogonal approaches for heparin identification, measurement of bioactivity and for detection of process impurities or contaminants in these drug products. Here we describe results from a survey of multiple lots from three types of LMWHs in the US market which were collected after the 2009 heparin sodium monograph revision. In addition, innovator and generic versions of formulated enoxaparin products purchased in 2011 are compared using these tests and found to be highly similar within the discriminating power of the assays applied.

    Global climate change is predicted to increase temperatures, alter geographical patterns of rainfall and increase the frequency of extreme climatic events. Such changes are likely to alter the timing and magnitude of drought stresses experienced by crops. This study used new developments in the classification of crop water stress to first characterize the typology and frequency of drought-stress patterns experienced by European maize crops and their associated distributions of grain yield, and second determine the influence of the breeding traits anthesis-silking synchrony, maturity and kernel number on yield in different drought-stress scenarios, under current and future climates. Under historical conditions, a low-stress scenario occurred most frequently (ca. 40%), and three other stress types exposing crops to late-season stresses each occurred in ca. 20% of cases. A key revelation shown was that the four patterns will also be the most dominant stress patterns under 2050 conditions. Future frequencies of low drought stress were reduced by ca. 15%, and those of severe water deficit during grain filling increased from 18% to 25%. Despite this, effects of elevated CO2 on crop growth moderated detrimental effects of climate change on yield. Increasing anthesis-silking synchrony had the greatest effect on yield in low drought-stress seasonal patterns, whereas earlier maturity had the greatest effect in crops exposed to severe early-terminal drought stress. Segregating drought-stress patterns into key groups allowed greater insight into the effects of trait perturbation on crop yield under different weather conditions. We demonstrate that for crops exposed to the same drought-stress pattern, trait perturbation under current climates will have a similar impact on yield as that expected in future, even though the frequencies of severe drought stress will increase in future. These results have important ramifications for breeding of maize and have implications for

After the regime change 1989 nothing happened in this market until 2008 when the Romanian renewable sector went through a remarkable boom. 5.000 MW new capacities were installed mainly in wind, PV and biomass plants but almost none in biogas plants. There is plenty of substrate available, some of it for free, and the support mechanism is also very generous when it comes to biogenic gas, so how come today there are less than 15 MW installed in biogas capacities? This question lies at the base of our research covering several company intern and extern aspects. This particular article addresses the risks induced by technology vs. the market risks on the basis of a study case from Romania. We analyse the profitability indicators of the first landfill gas recovery facility from Romania which was after implementation less profitable than expected.

    The economic situation of ''Konin'' brown coal mine located in Central Poland is analysed. The main problem of the mine is the coal price which is still regulated despite market economy. It causes many difficulties and therefore a change of energy policy is postulated. The basic economic results for 1993 as well as prognosis of investment costs up to 2020 are given. The changes of management system and the strategy planning training are also described. 2 ills, 1 tab

    This study extends the market mapping concept introduced by Counts et al. (Counts, M.E., Hsu, F.S., Tewes, F.J., 2006. Development of a commercial cigarette "market map" comparison methodology for evaluating new or non-conventional cigarettes. Regul. Toxicol. Pharmacol. 46, 225-242) to include both temporal cigarette and testing variation and also machine smoking with more intense puffing parameters, as defined by the Massachusetts Department of Public Health (MDPH). The study was conducted over a two year period and involved a total of 23 different commercial cigarette brands from the U.S. marketplace. Market mapping prediction intervals were developed for 40 mainstream cigarette smoke constituents and the potential utility of the market map as a comparison tool for new brands was demonstrated. The over-time character of the data allowed for the variance structure of the smoke constituents to be more completely characterized than is possible with one-time sample data. The variance was partitioned among brand-to-brand differences, temporal differences, and the remaining residual variation using a mixed random and fixed effects model. It was shown that a conventional weighted least squares model typically gave similar prediction intervals to those of the more complicated mixed model. For most constituents there was less difference in the prediction intervals calculated from over-time samples and those calculated from one-time samples than had been anticipated. One-time sample maps may be adequate for many purposes if the user is aware of their limitations. Cigarette tobacco fillers were analyzed for nitrate, nicotine, tobacco-specific nitrosamines, ammonia, chlorogenic acid, and reducing sugars. The filler information was used to improve predicting relationships for several of the smoke constituents, and it was concluded that the effects of filler chemistry on smoke chemistry were partial explanations of the observed brand-to-brand variation.

    Operation and maintenance (O&M) of wind turbines is recently becoming the spotlight in the wind energy sector. While wind turbine power capacities continue to increase and new offshore developments are being installed, O&M costs keep raising. With the objective of reducing such costs, the new trends are moving from corrective and preventive maintenance toward predictive actions. In this scenario, condition monitoring (CM) has been identified as the key to achieve this goal. The induction generator of a wind turbine is a major contributor to failure rates and downtime where doubly-fed induction generators (DFIG) are the dominant technology employed in variable speed wind turbines. The current work presents the analysis of an in-service DFIG. A one-year measurement campaign has been used to perform the study. Several signal processing techniques have been applied and the optimal method for CM has been identified. A diagnosis has been reached, the DFIG under study shows potential gearbox damage.

    The effects of heating conditions on critical current properties and microstructures of undoped MgB 2 bulks were systematically studied. Strong correlation was observed between J c and microstructures. The network structure with an excellent inter-grain connectivity of MgB 2 grains contributed to high-J c under low magnetic fields, and small grain size of MgB 2 enhanced the grain boundary flux pinning. Long time heating at low temperatures below the melting point of magnesium was discovered to be most effective for synthesis of MgB 2 bulks having strongly connected MgB 2 network structure with small grains. The sample heated at 550 deg. C for 1200 h recorded a high-J c of 4.02 x 10 5 A cm -2 at 20 K in self-field, while high-temperature and long time heating brought a significant grain growth which resulted in low J c

  14. Sarcopenia: An Undiagnosed Condition in Older Adults. Current Consensus Definition: Prevalence, Etiology, and Consequences

    2012-01-01

    Sarcopenia, the age associated loss of skeletal muscle mass and function, has considerable societal consequences for the development of frailty, disability and health care planning. A group of geriatricians and scientists from academia and industry met in Rome, Italy on November 18, 2009 to arrive at a consensus definition of sarcopenia. The current consensus definition was approved unanimously by the meeting participants and is as follows: Sarcopenia is defined as the age-associated loss of skeletal muscle mass and function. The causes of sarcopenia are multi-factorial and can include disuse, altered endocrine function, chronic diseases, inflammation, insulin resistance, and nutritional deficiencies. While cachexia may be a component of sarcopenia, the two conditions are not the same. The diagnosis of sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health. Sarcopenia should specifically be considered in patients who are bedridden, cannot independently rise from a chair, or who have a measured gait speed less that 1.0 m·s−1. Patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry (DXA) with sarcopenia being defined using currently validated definitions. A diagnosis of sarcopenia is consistent with a gait speed of less than 1 m·s−1 and an objectively measured low muscle mass (eg: appendicular mass relative to ht2 that is ≤ 7.23 kg/ m2 in men ≤ 5.67 kg/ m2 in men). Sarcopenia is a highly prevalent condition in older persons that leads to disability, hospitalization and death. PMID:21527165

    Vibrio cholerae is a globally distributed water-borne pathogen that causes severe diarrheal disease and mortality, with current outbreaks as part of the seventh pandemic. Further understanding of the role of environmental factors in potential pathogen distribution and corresponding V. cholerae disease transmission over time and space is urgently needed to target surveillance of cholera and other climate and water-sensitive diseases. We used an ecological niche model (ENM) to identify environmental variables associated with V. cholerae presence in marine environments, to project a global model of V. cholerae distribution in ocean waters under current and future climate scenarios. We generated an ENM using published reports of V. cholerae in seawater and freely available remotely sensed imagery. Models indicated that factors associated with V. cholerae presence included chlorophyll-a, pH, and sea surface temperature (SST), with chlorophyll-a demonstrating the greatest explanatory power from variables selected for model calibration. We identified specific geographic areas for potential V. cholerae distribution. Coastal Bangladesh, where cholera is endemic, was found to be environmentally similar to coastal areas in Latin America. In a conservative climate change scenario, we observed a predicted increase in areas with environmental conditions suitable for V. cholerae. Findings highlight the potential for vulnerability maps to inform cholera surveillance, early warning systems, and disease prevention and control. Copyright © 2015 The Authors.

    2012-01-01

    The plasma parameters such as electron distribution function and electron density of three atmospheric-pressure transient discharges namely filamentary and homogeneous dielectric barrier discharges in air, and the spark discharge of an argon plasma coagulation (APC) system are determined. A combination of numerical simulation as well as diagnostic methods including current measurement and optical emission spectroscopy (OES) based on nitrogen emissions is used. The applied methods supplement each other and resolve problems, which arise when these methods are used individually. Nitrogen is used as a sensor gas and is admixed in low amount to argon for characterizing the APC discharge. Both direct and stepwise electron-impact excitation of nitrogen emissions are included in the plasma-chemical model applied for characterization of these transient discharges using OES where ambiguity arises in the determination of plasma parameters under specific discharge conditions. It is shown that the measured current solves this problem by providing additional information useful for the determination of discharge-specific plasma parameters. (paper)

    The Sustained Spheromak Physics Experiment (SSPX) was a toroidal magnetic-confinement device without toroidal magnetic-field coils or a central transformer but which generated core-plasma currents by dynamo processes driven by coaxial plasma-gun injection into a flux-conserving vessel. Record electron temperatures in a spheromak (Te˜500eV) were achieved, and final results of the SSPX program were reported in [1]. Plasma density, which depended strongly on wall conditions, was an important parameter in SSPX. It was observed that density rises with Igun and that confinement improved as the density was lowered. Shortly after the last experiments, a new feature was added to the Corsica code's solver used to reconstruct SSPX equilibria. Motivated by n=0 fields observed in NIMROD simulations of SSPX, an insulating boundary condition was implemented at the plasma-gun gap. Using this option we will perform new reconstructions of SSPX equilibria and look for correlations between the location of the separatrix (which moves up the gun wall and onto the insulating gap as Igun increases) and plasma density and magnetic-flux amplification [2].[4pt] [1] H.

These treatments could induce changes in physical and chemical properties of treated samples. To investigate the charge storage mechanism of the insulating dielectrics after high-voltage corona discharge, the relaxation processes responsible for corona charged polyimide films under different poling conditions were analyzed by the Thermally Stimulated Discharge Currents method (TSDC. In the results of thermal relaxation process, the appearance of various peaks in TSDC spectra provided a deep insight into the molecular status in the dielectric material and reflected stored space charge relaxation process in the insulating polymers after corona discharge treatments. Furthermore, the different space charge distribution status under various poling temperature and different discharge voltage level were also investigated, which could partly reflect the influence of the ambiance condition on the functional dielectrics after corona poling.

    A number of studies have been concerned with the evaporation rates under martian conditions in order to place limits on the possible survival time of both liquid water and ice exposed on the surface of Mars. Such studies also aid in assessing the efficacy of an overlying layer of dust or loose regolith material in providing a barrier to free evaporation and thus prolong the lifetime of water in locations where its availability to putative living organisms would be significant. A better quantitative understanding of the effects of phase changes of water in the near surface environment would also aid the evaluation of the possible role of water in the formation of currently observed features, such as gullies in cliff walls and relatively short-term changes in the albedo of small surface areas ('dark stains'). Laboratory measurements aimed at refinement of our knowledge of these values are described here. The establishment of accurate values for evaporation rates and their dependence on the physical conditions of temperature, pressure and energy input, is an important benchmark for the further investigation of the efficacy of barriers to free evaporation in providing a prolonged period of survival of the water, particularly as a liquid.

    2017-04-01

    Although ocean surface waves are known to play an important role in the momentum and other scalar transfer between the atmosphere and the ocean, most operational numerical models do not explicitly include the terms of wave-current interaction. In this work, a numerical analysis about the relative importance of the processes associated with the wave-current interaction under strong off-shore wind conditions in Gulf of Tehuantepec (the southern Mexican Pacific) was carried out. The numerical system includes the spectral wave model WAM and the 3D hydrodynamic model POLCOMS, with the vertical turbulent mixing parametrized by the kappa-epsilon closure model. The coupling methodology is based on the vortex-force formalism. The hydrodynamic model was forced at the open boundaries using the HYCOM database and the wave model was forced at the open boundaries by remote waves from the southern Pacific. The atmospheric forcing for both models was provided by a local implementation of the WRF model, forced at the open boundaries using the CFSR database. The preliminary analysis of the model results indicates an effect of currents on the propagation of the swell throughout the study area. The Stokes-Coriolis term have an impact on the transient Ekman transport by modifying the Ekman spiral, while the Stokes drift has an effect on the momentum advection and the production of TKE, where the later induces a deepening of the mixing layer. This study is carried out in the framework of the project CONACYT CB-2015-01 255377 and RugDiSMar Project (CONACYT 155793).

    The current status of the debate is characterised by heterogeneity, which can be perceived reading the body of opinions given by the EC Commission, the European Parliament, the EC Council of Ministers, or the national governments, and in the opinions of the European Parliament or the respective national parliaments, the scope of diverging attitudes ranging from anticipating obedience in single cases to anticipating refusal. There is a growing awareness of the distinctions between the gas and the power industry and their respective requirements, leading to increasing discussions about suitable policies. The EC Commission has put down some basic principles, but their proposal of establishing a scheme of Third Party Access on a voluntary basis is a wolf in sheep's clothing, because in case this voluntary scheme will not work, more stringent instruments are on the list. There is general confusion to be stated, which might indicate that the existing systems are not so bad after all. (orig.) [de

    Full Text Available With the advent of social media where customers have the technical ability to upload own content the change occurred in some of the communication habits online. This world of constant communication is a challenge for businesses as well researchers. Academic research in this area is bringing valuable insights into people attitudes and behaviour on the social media. What is the current situation and where the research field is heading is a question of high importance. This study uses the systematic approach to reviewing the literature and to show the development of publications produced at Czech universities. Although the results show an increasing number of studies, Czech research is lagging behind other similar countries. Compared with the best countries, it is lagging behind in the number of quotations per article. On the basis of these analyses, suggestions for future research that can help to promote future theory development are proposed.

    Full Text Available The article deals with the questions of the definition of the semi-constant component of current liabilities of a bank. The purpose of this article is to develop a scientific and methodological approach to determine the semi-constant component of the current liabilities of a bank under the conditions of the complexity of data acquisition and processing of the data on factors that influence on demand deposits. The main hypothesis is the assumption of the heterogeneity of the variance of the daily cumulative sum of demand deposits. The analysis of scientific and methodological approaches that allow determining a stable component of current liabilities proves the need for further improvement of scientific instruments. In particular, a coefficient analysis that is proposed by some of the scholars, mainly, considers the average values of turnover on accounts, which in turn, can vary considerably throughout the calendar year. The use of the probability distributions to determine the expected value of the constant sum of deposits is possible only in the case of “ideal” financial conditions, when the impact of factors on the aggregate sum of deposits is not taken into account. The developed statistical models leave out the possible heterogeneity of the dispersion of this balance. In the article, it is proposed to apply econometric methods, namely, the methods of time series analysis to test the hypothesis of the variance heterogeneity of the cumulative sum of demand deposits, using daily data. In particular, the formalization and evaluation of EGARCH-model parameters are conducted. The EGARCH-model allows to take into account the non-linear, asymmetric effects of fluctuations in the financial series. The determination of the conditionalconstant component of demand deposits is proposed on the basis of the revealed regularities. The results of the research prove the hypothesis of the non-stationary character of the variance in daily balance of demand

    Full Text Available The purpose of the article is to detect crop production on agricultural enterprises clusters at a price by defining their amplitude of price fluctuations. Methodology. The study is based on grouping of statistical data from agricultural enterprises using cluster analysis, followed by reliability evaluation of pre-selected clusters by t-test and charting the scope by the selected index. Cluster analysis of agricultural enterprises in Ukraine has been conducted using "STATISTICA" program. Distance between clusters was calculated as the Euclidean distance. The object of the study was data on the prices for agricultural enterprises by regions of Ukraine in 2013. As a result, an appropriate number of groups according to the produce types in the regions of Ukraine, plane in market prices, have been determined. The process of consistent combination of objects in clusters is shown in the graphs as agglomerative clustering dendrogram of the regions of Ukraine for such products as wheat, grain corn and sunflower seeds. In general, there have been examined: 7311 businesses growing wheat, 5034 – growing corn and 6124 companies growing sunflower. Results. During a year-long study of price fluctuations in agricultural enterprises within regions of Ukraine similarities in nature of absolute and relative changes in the formed clusters were established. Four clusters on wheat, five clusters on corn, three clusters on sunflower seeds have been allocated during the study. The study of the selected groups confirms significant differences between them and allows the sectors and enterprises of the cluster with high variability of prices to build their own marketing strategy based on the position of expectations and search for sale options according to the most favorable price. Practical value. The established differences on the selected clusters make it possible to forecast the price situation in various regions of Ukraine in terms of its differences from average

    Recombinant immunotherapeutics are important biologics for the treatment and prevention of various diseases. Immunotherapy can be divided into two categories, passive and active. For passive immunotherapy, the successes of antibody and cytokine therapeutics represent a promising future and opportunities for improvements. Efforts, such as cell engineering, antibody engineering, human-like glycosylation in yeast, and Fab fragment development, have led the way to improve antibody efficacy while decreasing its high manufacturing costs. Both new cytokines and currently used cytokines have demonstrated therapeutic effects for different indications. As for active immunotherapy, recently approved HPV vaccines have encouraged the development of preventative vaccines for other infectious diseases. Immunogenic antigens of pathogenic bacteria can now be identified by genomic means (reverse vaccinology). Due to the recent outbreaks of pandemic H1N1 influenza virus, recombinant influenza vaccines using virus-like particles and other antigens have also been engineered in several different recombinant systems. However, limitations are found in existing immunotherapeutics for cancer treatment, and recent development of therapeutic cancer vaccines such as MAGE-A3 and NY-ESO-1 may provide alternative therapeutic strategy.

  8. Three Gorges Reservoir Area: soil erosion under natural condition vs. soil erosion under current land use

    Apparently, the current most prominent human-induced example for large scale environmental impact is the Three Gorges Dam in China. The flooding alongside the Yangtze River, and its tributaries results in a vast loss of settlement and farmland area with productive, fertile valley soils. Due to the associated high land use dynamic on uphill-sites, the soil resources are underlying high land use pressure. Within our study, the soil erosion under natural conditions is compared to the soil erosion under current land use after the impoundment. Both were modeled using the empirical Universal Soil Loss Equation (USLE) which is able to predict long-term annual soil loss with limited data. The database consists of digital terrain data (45 m resolution DEM, erosive slope length based on Monte-Carlo-Aggregation according to Behrens et al. (2008)), field investigations of recent erosion forms, and literature studies. The natural disposition to soil erosion was calculated considering the USLE factors R, S, and K. The soil erosion under current land use was calculated taking into account all USLE factors. The study area is the catchment of the Xiangxi River in the Three Gorges Reservoir area. Within the Xiangxi Catchment (3,200 km²) the highly dynamic backwater area (580 km²), and two micro-scale study sites (Xiangjiaba with 2.8 km², and Quyuan with 88 km²) are considered more detailed as they are directly affected by the river impoundment. Central features of the Xiangxi Catchment are the subtropical monsoon climate, an extremely steep sloping relief (mean slope angle 39°, SD 22.8°) artificially fractured by farmland terraces, and a high soil erodibility (mean K factor 0.37, SD 0.13). On the catchment scale the natural disposition to soil erosion makes up to mean 518.0 t ha-1 a-1. The maximum potential soil loss of 1,730.1 t ha-1 a-1 under natural conditions is reached in the Quyuan site (mean 635.8 t ha-1 a-1) within the backwater area (mean 582.9 t ha-1 a-1). In the

    Generation and amplification mechanisms of ocean waves are well understood under constant wind speed or limited fetch conditions. Under these situations, the momentum and energy transfers from air to water are also quite well known. However during the wind field evolution over the ocean, we may observe sometime high wind acceleration/deceleration situations (e.g. Mexican Tehuano or Mediterranean Mistral wind systems). The evolution of wave systems under these conditions is not well understood. The purpose of these laboratory experiments is to better understand the early stages of water-waves and surface-drift currents under non-stationary wind conditions and to determine the balance between transfers creating waves and surface currents during non-equilibrium situations. The experiments were conducted in the Institut Pythéas wind-wave facility in Marseille-France. The wave tank is 40 m long, 2.7 m wide and 1 m deep. The air section is 50 m long, 3 m wide and 1.8 m height. We used 11 different resistive wave-gauges located along the tank. The momentum fluxes in the air column were estimated from single and X hot-film anemometer measurements. The sampling frequency for wind velocity and surface displacement measurements was 256 Hz. Water-current measurements were performed with a profiling velocimeter. This device measures the first 3.5 cm of the water column with a frequency rate of 100Hz. During the experiments, the wind intensity was abruptly modified with a constant acceleration and deceleration over time. We observed that wind drag coefficient values for accelerated wind periods are lower than the ones reported in previous studies for constant wind speed (Large and Pond 1981; Ocampo-Torres et al. 2010; Smith 1980; Yelland and Taylor 1996). This is probably because the turbulent boundary layer is not completely developed during the increasing-wind sequence. As it was reported in some theoretical studies (Miles 1957; Phillips 1957; Kahma and Donelan 1988), we

The paper examines how competing actors and their ideas on market integration developed new services for direct marketing according to their respective origins and tried to shape the regulatory framework. The paper analyses this process and explains the current shape of the field of direct marketing. Medium-sized structured actors, who favoured RES-E integration via the conventional wholesale power markets, and who formed early close coalitions with RES-E power producers at the same time, have been most successful in terms of market shares. Moreover, they have been very successful for different reasons in building-up coalitions with governance units and influencing the field rules and routines. Based on those findings, the paper will conclude with some policy advices for the future adjustment of the current regulative frameworks. As long as there is no evidence of how RES-E can be integrated most effectively and efficiently, policies should maintain a competition between different direct marketing strategies to find out which strategies serve the best in terms of achieving a successful energy transition. - Highlights: • Innovation sociological analysis of the market integration of electricity from renewables in the German electricity markets. • Direct marketing of RES-E seen as a new strategic action field in the German “Energiewende”. • Strategies of incumbent and challenger actors to shape the rules of the field. • Suggestions for the future design of policy instruments for direct marketing of RES-E

    Aging process is characterized by difficulties in ensuring balance control, especially in conditions of reduced or conflicting sensory information, leading to an increased risk of falling. Conversely, the practise of physical activities (PA) has been recognized as a good approach to improve the quality of balance control. This study aimed to investigate the influence of current and/or past PA on balance-related neurosensorial organization in older adults on the maintenance of the upright stance, especially during sensory conflicting situations. Postural control was evaluated by means of the Sensory Organization Test on 130 healthy noninstitutionalized volunteers aged over 65, split into four groups according to the presence or absence of PA before or after retirement. Subjects who practised PA for a long time (Gr1) and subjects who started PA after retirement (Gr2) displayed the best postural performances and better managed sensory conflicting situations compared to subjects who had stopped PA for many years (Gr3) and subjects who had never practised PA (Gr4). Multiple regression analyses revealed that current PA was the major determinant for postural parameters during sensorial conflict compared to age, gender, body mass index and past PA. Regular PA, even when started late in life, allows appropriate reorganization of the different components of postural control during sensory conflicting situations. Indeed, active subjects were more able to compensate for suppressed or perturbed sensory information by an increased usage of another referential and so to correct their posture by adopting a more appropriate balance strategy. Thus, PA counteracts the age-related decline of postural control and could consequently reduce the risk of falling.

    Full Text Available Introduction. The number, range, and diversity of events with a character of festivals have been growing in the Lublin Region over the last several years. The events are organised by various entities and institutions. Information about them is largely dispersed. No study has been conducted so far determining the spatial distribution of festivals at the regional scale, and analysing their offer in the context of possibilities of development of festival tourism. Therefore, a study in the scope was undertaken with consideration of the cultural conditionings of some of the events. Material and methods. In periods from July to December 2010 and from September to December 2013, secondary information was analysed (statistics, records, and scientific studies, and original material was collected (field inventory, interview, and diagnostic survey regarding the current condition of festival tourism in the Lublin Region. Results. The collected data on festival tourism offers suggest that the number of festivals in the Lublin Region has been continuously increasing from year to year. According to the obtained data, festivals with a duration of 3 and 5 days are dominant. The majority of festivals are held in summer months, usually on weekends. Music and interdisciplinary festivals with international, national, and regional range are prevalent. Some of them already have a history of 47 years. The analysis of the spatial distribution of the festivals subject to the inventory suggests that the majority of them are organised in the largest cities of the region, namely Lublin, Zamośæ, and Kazimierz Dolny. Conclusions. Due to the very diverse offer of festivals, and the manner of their promotion, they play an important role in the promotion of the Lublin Region. The offer, spatial distribution, and dynamics in the scope of organisation of festivals provide good perspectives for the development of festival tourism in the Lublin Region.

  16. How does Germany's green energy policy affect electricity market volatility? An application of conditional autoregressive range models

    2016-01-01

    Based on a dynamic model for the high/low range of electricity prices, this article analyses the effects of Germany's green energy policy on the volatility of the electricity market. Using European Energy Exchange data from 2000 to 2015, we find rather high volatility in the years 2000–2009 but also that the weekly price range has significantly declined in the period following the year 2009. This period is characterised by active regulation under the Energy Industry Law (EnWG), the EU Emissions Trading Directive (ETD) and the Renewable Energy Law (EEG). In contrast to the preceding period, price jumps are smaller and less frequent (especially for day-time hours), implying that current policy measures are effective in promoting renewable energies while simultaneously upholding electricity market stability. This is because the regulations strive towards a more and more flexible and market-oriented structure which allows better integration of renewable energies and supports an efficient alignment of renewable electricity supply with demand. - Highlights: • We estimate a CARR model for German electricity price data. • We augment the model by dummies capturing important regulations. • We find a significant decline in the price range after the year 2009. • This implies effective price stabilisation by German energy policy.

    Full Text Available The aim of the article is to determine the degree of interdependence of stock markets in separate countries of the European Union, namely: France, Germany, Great Britain, Poland, the Czech Republic and Hungary on the basis of studying the changes in stock indexes, as well as determining the existence of tendencies of approximating the dynamics of the national stock index «PFTS Index» to the corresponding dynamics of stock indexes in surveyed countries. The article analyzes the dynamics of changes in stock indices in the UK (FTSE, Germany (DAX 30, France (CAC 40 and pan-European ones (EURO STOXX 50, as well as changes in stock indices in Poland (WIG 20, Czech Republic (PX, Hungary (BUX. Calculations of the coefficients of pair correlation between changes in stock indices in the studied countries have been performed. The calculation results show a substantial connection between the indicators of changes in stock indices and allow to make a conclusion that in the dynamics of stock indices of national stock markets of the studied EU countries some common trends are observed, moreover, in the behavior of the considered indices common local trends are noticed as well. The author calculated the coefficient of pair correlation between the indicators of changes in the national stock index «PFTS Index» and the stock indices of the «old» and «new» EU countries. The calculations showed that the PFTS Index does not demonstrate a high level of correlation with stock indices of the «old» EU countries and has a tendency of approaching the corresponding dynamics of stock indices of the «new» EU countries.

    Full Text Available This study used a spatially-explicit model to identify the amount and spatial distribution of economically feasible sites for establishing dedicated energy crops under various market and policy scenarios. A sensitivity analysis was performed for a biomass market with different discount rates and biomass prices as well as policy scenarios including propriety tax exemption, carbon offset payments, and the inclusion of farmland for biomass production. The model was applied to a four-county study area in Kentucky representing conditions commonly found in the Ohio River Valley. Results showed that both biomass price and discount rate have a can strongly influence the amount of economically efficient sites. Rising the biomass price by 5 $·t−1 and lowering discount rate by 1% from the baseline scenario (40 $·t−1 and 5% resulted in an over fourteen fold increment. Property tax exemption resulted in a fourfold increase, a carbon payment on only 1 $·t−1 caused a twelve fold increase and extending the landbase from marginal land to farmland only slightly increase the economically efficient sites. These results provide an objective evaluation of market and policy scenarios in terms of their potential to increase land availability for establishing dedicated energy crops and to promote the bioenergy industry.

    This study investigated the current situation and environmental conditions of green mussel Perna viridis farming in Surat Thani, Phetchaburi and Samut Prakan provinces where were located in the gulf of Thailand. Samples were collected during April, August and November in 2014. Based on the results of this study, there were three major types of mussel culture patterns in Thailand: bouchot culture, longline culture (rope culture), and raft culture. Mussel farmers encountered problems on decreasing of larvae mussel in the water column, water quality degradation, high production cost and farmer’s lack of negotiation power to control the price. The water quality of the mussel farms, such as dissolved oxygen (DO), pH, salinity, electrical conductivity (EC), fecal coliforms bacteria and the total coliforms bacteria met the standard for aquaculture. However, the nutrient, such as ammonium (NH4-N), nitri-nitrogen (NO2-N), nitrate-nitrogen (NO3-N) and soluble reactive phosphorus (PO4-P) were higher than the value of marine aquaculture standard. The results of the contamination of Salmonella spp. bacteria were not found in the mussel’s tissue, however Escherichia coli was found at very low level.

    Highlights: •EBSD of electroplated Zn on Fe or steel was performed. •Zn grows epitaxially on electropolished ferritic steel following Burger's orientation relation. •Surface deformation of steel leads to multiple electroplated zinc grains with random orientation. •Zn grows epitaxially even on industrial surfaces with little surface deformation. •Multiple zinc grains on one steel grain can show identical orientation relations. -- Abstract: The dependence of the crystal orientation of electrodeposited zinc of the grain orientation on ferritic steel substrate at high current density deposition (400 mA cm −2 ) during a pulse-plating process was investigated by means of EBSD (electron backscatter diffraction) measurements. EBSD-mappings of surface and cross-sections were performed on samples with different surface preparations. Furthermore an industrial sample was investigated to compare lab-coated samples with the industrial process. The epitaxial growth of zinc is mainly dependent on the condition of the steel grains. Deformation of steel grains leads to random orientation while zinc grows epitaxially on non-deformed steel grains even on industrial surfaces

    Due to declining wholesale prices for electricity, the profitability of base load power and heat generation plants decreases significantly. Therefore, concepts such as the increased use of electricity or natural plant flexibility have to be developed. The improved framework conditions by means of the amended Combined Heat and Power Act are helpful. When modernising plants, it is even possible under favorable conditions and with a good concept to fully refinance the investment on the CHP surcharges.

    The basic way to improve the performance of a superconducting current limiter is to apply and evaluate a superconducting device that is appropriate to the superconducting current limiter. Among the many types of superconducting devices, the YBCO thin film wire has excellent current-limiting performance that is appropriate for actual system application. For the application of the YBCO thin film wire to superconducting current limiters, its current-limiting performance as a unit device must be accurately evaluated, and measures to improve its current-limiting performance must be sought. Accordingly, to evaluate the current-limiting performance of the YBCO thin film wire, this study was conducted to evaluate its resistance-increasing trend, V max , T r , I max , I qt , and current-limiting rate as a unit device, after which the electric coupling condition that consists of a core and windings was used to evaluate the current-limiting performance of the YBCO thin film wire.

    2015-04-01

    Target specific anticoagulants (TSOACs) have recently been introduced to the US market for multiple indications including venous thromboembolism (VTE) prevention in total hip and knee replacement surgeries, VTE treatment and reduction in the risk of stroke in patients with non-valvular atrial fibrillation (NVAF). Currently, three TSOACs are available including rivaroxaban, apixaban, and dabigatran with edoxaban currently under Food and Drug Administration review for VTE treatment and stroke prevention in NVAF. The introduction of these agents has created a paradigm shift in anticoagulation by considerably simplifying treatment and anticoagulant initiation for patients by giving clinicians the opportunity to use a rapid onset, rapid offset, oral agent. The availability of these rapid onset TSOACs is allowing for outpatient treatment of low risk pulmonary embolism and deep vein thrombosis which can greatly reduce healthcare costs by avoiding inpatient hospitalizations and treatment for the disease. Additionally with this practice, the complications of an inpatient hospitalization may also be avoided such as nosocomial infections. Single-agent approaches with TSOACs represent a paradigm shift in the treatment of VTE versus the complicated overlap of a parenteral agent with warfarin. Transitions between anticoagulants, including TSOACs, are a high-risk period for the patient, and clinicians must carefully consider patient characteristics such as renal function as well as the agents that are being transitioned. TSOAC use appears to be growing slowly with improved payment coverage throughout the US.

    Full Text Available Cheese type cabacinha from Vale do Jequitinhonha is obtained by curd heating in a similar process made to Mozzarella, but the raw milk is unpasteurized and the final product is stored unpackaged and at room temperature. This milk derivative may contribute to the increase the income of the local population, especially the residents of the edges of roads, due to the flow of vehicles and possible buyers. The purpose of this work was to identify the physical and sanitary conditions of cheese type cabacinha market places present in three municipalities of the Vale do Jequitinhonha, MG, Brazil. Previously the investigation was detected the number of marketplaces that sell these cheese in the Medina, Cachoeira de Pajeú and Pedra Azul, municipalities of the state of Minas Gerais, Brazil, located on the surrounding area of the highways BR 251 and BR 116. Afterward as developed a physical and sanitary checklist and it were filled in loco. It was observed that most market places were not provided of masonry walls, piped water or toilet and sink. It is also common to the presence of possible contamination vectors in surroundings, such as dogs and insects. It is verified that most of these cheese is exposed in pairs held by string and unpackaged. This study demonstrated the precariousness of the physical structures and consequently the lack of adequate sanitary conditions in the cheese type cabacinha market places. Because it is an artisanal product from family farming, which generates income and employment in the field deserve more attention of competent state and municipal authorities.

    Full Text Available Uno de los temas indagados en el Segundo estudio nacional realizado por el Observatorio Costarricense de Mipymes durante el 2011 corresponde al financiamiento de las micros, pequeñas y medianas empresas costarricenses. Se consultaron las fuentes de financiamiento más utilizadas, la presentación de solicitudes de crédito durante los últimos cinco años, la utilización que en general hacen estas empresas de los diferentes medios de financiamiento y sus requerimientos actuales. De forma similar a lo que ocurre en otros países, los fondos propios constituyen la principal opción para estas empresas. Por ello, en este trabajo han sido analizadas las condiciones que propician la autofinanciación o el uso de otras opciones. Por medio del análisis estadístico de la información recopilada en la encuesta, se comprueba que algunas variables relativas a la gestión empresarial, tales como la fuente de financiamiento inicial, la experiencia del (de la empresario(a y la prioridad que dan al manejo de aspectos financieros, presentan una asociación significativa con las estrategias de financiamiento en las mipymes costarricenses. ABSTRACT Financing was one of the areas investigated in the Second National Survey of micro, small and medium sized Costa Rican companies during 2011. The most used financing sources, credit applications during the last five years, end use of this credit, and current credit requirements in various financing institutions were investigated. Similar to other countries, own funding was the main option for these companies. Thus, this work examines the conditions that facilitate the use of self financing or other options available. Through statistic analysis of the information collected, variables like initial funding source, previous experience of the entrepreneur and priority given to financial management were shown to present a definite relationship to financing strategies for Costa Rican SMEs.

    Conditions data (for example: alignment, calibration, data quality) are used extensively in the processing of real and simulated data in ATLAS. The volume and variety of the conditions data needed by different types of processing are quite diverse, so optimizing its access requires a careful understanding of conditions usage patterns. These patterns can be quantified by mining representative log files from each type of processing and gathering detailed information about conditions usage for that type of processing into a central repository.

    Anodic TiO2 nanotubes have been studied extensively for many years. However, the growth kinetics still remains unclear. The systematic study of the current transient under constant anodizing voltage has not been mentioned in the original literature. Here, a derivation and its corresponding theoretical formula are proposed to overcome this challenge. In this paper, the theoretical expressions for the time dependent ionic current and electronic current are derived to explore the anodizing process of Ti. The anodizing current-time curves under different anodizing voltages and different temperatures are experimentally investigated in the anodization of Ti. Furthermore, the quantitative relationship between the thickness of the barrier layer and anodizing time, and the relationships between the ionic/electronic current and temperatures are proposed in this paper. All of the current-transient plots can be fitted consistently by the proposed theoretical expressions. Additionally, it is the first time that the coefficient A of the exponential relationship (ionic current jion = A exp(BE)) has been determined under various temperatures and voltages. And the results indicate that as temperature and voltage increase, ionic current and electronic current both increase. The temperature has a larger effect on electronic current than ionic current. These results can promote the research of kinetics from a qualitative to quantitative level.

  14. Risk analysis for CHP decision making within the conditions of an open electricity market

    Al-Mansour, Fouad; Kozuh, Mitja

    2007-01-01

    Decision making under uncertainty is a difficult task in most areas. Investment decisions for combined heat and power production (CHP) are certainly one of the areas where it is difficult to find an optimal solution since the payback period is several years and parameters change due to different perturbing factors of economic and mostly political nature. CHP is one of the most effective measures for saving primary energy and reduction of greenhouse gas emissions. The implementation of EU directives on the promotion of cogeneration based on useful heat demand in the internal energy market will accelerate CHP installation. The expected number of small CHP installations will be very high in the near future. A quick, reliable and simple tool for economic evaluation of small CHP systems is required. Since evaluation is normally made by sophisticated economic computer models which are rather expensive, a simple point estimate economic model was developed which was later upgraded by risk methodology to give more informative results for better decision making. This paper presents a reliable computer model entitled 'Computer program for economic evaluation analysis of CHP' as a tool for analysis and economic evaluation of small CHP systems with the aim of helping the decision maker. The paper describes two methods for calculation of the sensitivity of the economic results to changes of input parameters and the uncertainty of the results: the classic/static method and the risk method. The computer program uses risk methodology by applying RISK software on an existing conventional economic model. The use of risk methodology for economic evaluation can improve decisions by incorporating all possible information (knowledge), which cannot be done in the conventional economic model due to its limitations. The methodology was tested on the case of a CHP used in a smaller hospital

    The impact of deregulation in the North American electricity market on the energy industry in Quebec was discussed. Increased competition, a direct result of deregulation, can lead to open markets for Quebec utilities. It is expected that Quebec utilities such as Hydro-Quebec and Gaz-Metropolitain will profit from an open market since consumers will have the choice of electricity suppliers that will best suit their needs. Open markets enabling Hydro-Quebec to sell at market prices in the American market present tremendous opportunities for Quebec utilities, especially in view of the lower production costs, the accumulated knowledge about energy markets, and their aggressive policy to form constructive partnerships..

    Predictions are that the space heating ventilation and air conditioning equipment sector will undergo significant expansion in the coming decade. Substantial technology inputs will be required to make new equipment conform to standards on energy efficiency and environmental compatibility, and strong competition in this sector will force equipment designers to seek low energy cost solutions. The European energy price situation is expected to favour the use of reversible gas heat pumps in space HVAC systems for buildings. New environmental regulations, especially those governing refrigerant typology, indoor air pollution and thermal comfort in office buildings, should also help to increase demand for new technologically advanced equipment conforming with international standards.

    1992-01-01

    Setting the acceleration regime in a microtron with the resonator in which the third accelerating field harmonic is excited by accelerated clusters is considered. It is shown that excitation of the accelerating field third harmonic in the microtron resonator (E 011 mode) causes a 1.5 time increase of the range of field intensity values under which resonance particle acceleration is possible. Under moderate energies and accelerated currents (10-15 MeV, 50-80 mA) this leads to a reduction of requirements to the stability of power coming to the resonator and cathode temperature. Under accelerated currents of > 100 mA the third harmonic complicates the microtron transition to acceleration regime. The microtron transfers to stable autooscillation regime, but the current achieved in a single short pulse is increased. By varying the value of the resonator quality factor on the third harmonic one can change the current pulse duration and autooscillation period

    Ocean surface boundary layer dynamics off the southern coast of France in the NW Mediterranean is investigated by using velocity observations by high-frequency (HF) radars, surface drifting buoys and a downward-looking drifting acoustic Doppler current profiler (ADCP). The analysis confirms that velocities measured by HF radars correspond to those observed by an ADCP at the effective depth z f = k -1, where k is wavenumber of the radio wave emitted by the radar. The radials provided by the radars were in a very good agreement with in situ measurements, with the relative errors of 1 and 9 % and root mean square (RMS) differences of 0.02 and 0.04 m/s for monostatic and bistatic radar, respectively. The total radar-based velocities appeared to be slightly underestimated in magnitude and somewhat biased in direction. At the end of the survey period, the difference in the surface current direction, based on HF radar and ADCP data, attained 10°. It was demonstrated that the surface boundary layer dynamics cannot be reconstructed successfully without taking into the account velocity variation with depth. A significant misalignment of ˜30° caused by the sea breeze was documented between the HF radar (HFR-derived) surface current and the background current. It was also found that the ocean response to a moderate wind forcing was confined to the 4-m-thick upper layer. The respective Ekman current attained the maximum value of 0.15 m/s, and the current rotation was found to be lagging the wind by approximately 40 min, with the current vector direction being 15-20° to the left of the wind. The range of velocity variability due to wind forcing was found comparable with the magnitude of the background current variability.

    The capacity of turbidity currents to carry sand and coarser sediment from shallow to deep regions in the submarine environment has attracted the attention of researchers from different disciplines. Yet not only are field measurements of oceanic turbidity currents a rare achievement, but also the data that have been collected consist mostly of velocity records with very limited or no suspended sediment concentration or grain size distribution data. This work focuses on two turbidity currents measured in Monterey Canyon in 2002 with emphasis on suspended sediment from unique samples collected within the body of these currents. It is shown that concentration and grain size of the suspended material, primarily controlled by the source of the gravity flows and their interaction with bed material, play a significant role in shaping the characteristics of the turbidity currents as they travel down the canyon. Before the flows reach their normal or quasi-steady state, which is defined by bed slope, bed roughness, and suspended grain size, they might pass through a preliminary adjustment stage where they are subject to capacity-driven deposition, and release heavy material in excess. Flows composed of fine (silt/clay) sediments tend to be thicker than those with sands. The measured velocity and concentration data confirm that flow patterns differ between the front and body of turbidity currents and that, even after reaching normal state, the flow regime can be radically disrupted by abrupt changes in canyon morphology.

    Conditions data (for example: alignment, calibration, data quality) are used extensively in the processing of real and simulated data in ATLAS. The volume and variety of the conditions data needed by different types of processing are quite diverse, so optimizing its access requires a careful understanding of conditions usage patterns. These patterns can be quantified by mining representative log files from each type of processing and gathering detailed information about conditions usage for that type of processing into a central repository. In this presentation, we describe the systems developed to collect this conditions usage metadata per job type and describe a few specific (but very different) ways in which it has been used. For example, it can be used to cull specific conditions data into a much more compact package to be used by jobs doing similar types of processing: these customized collections can then be shipped with jobs to be executed on isolated worker nodes (such as HPC farms) that have no netwo...

    Environmental conditions in early life are known to have impacts on later health outcomes, but causal mechanisms and potential remedies have been difficult to discern. This paper uses the Nepal Demographic and Health Surveys of 2006 and 2011, combined with earlier NASA satellite observations of variation in the Normalized Difference Vegetation Index (NDVI) at each child's location and time of birth to identify the trimesters of gestation and periods of infancy when climate variation is linked to attained height later in life. We find significant differences by sex: males are most affected by conditions in their second trimester of gestation, and females in the first three months after birth. Each 100-point difference in NDVI at those times is associated with a difference in height-for-age z-score (HAZ) measured at age 12-59 months of 0.088 for boys and 0.054 for girls, an effect size similar to that of moving within the distribution of household wealth by close to one quintile for boys and one decile for girls. The entire seasonal change in NDVI from peak to trough is approximately 200-300 points during the 2000-2011 study period, implying a seasonal effect on HAZ similar to one to three quintiles of household wealth. This effect is observed only in households without toilets; in households with toilets, there is no seasonal fluctuation, implying protection against climatic conditions that facilitate disease transmission. We also use data from the Nepal Living Standards Surveys on district-level agricultural production and marketing, and find a climate effect on child growth only in districts where households' food consumption derives primarily from their own production. Robustness tests find no evidence of selection effects, and placebo regression results reveal no significant artefactual correlations. The timing and sex-specificity of climatic effects are consistent with previous studies, while the protective effects of household sanitation and food markets are

    The conception Middle East is being interpreted in so many ways as the legendary fiction and tales which are being told of the country of the early caliph. Similar is the variety of the climatic zones, the economic systems and the political structure in this region. Homogeneous are really only the national characteristics of the people living in the region (orientals and semites), and their religion (Islam). Normally one understands by the expression - Middle East - the Asiatic States of the Mediterranean Sea and the Arabic States of Asia. These zones comprise climatically etesian climates (Lebanon, parts of Syria), alpine climates (Iraqi Kurdland), desert and grassland climates with rainfalls of 250 mm/annum but also tropical climate (South Jemen). Of similar variety are the characteristics of the states: we find republics, kingdoms and federal states in most instances with one governing class of rich people or party members and a mass of poor people. Fairly uniform are the economics - a state centralism. The state directs and invests, dependent on the country the liberalism of commerce is graduated differently. In rough outlines one can distinguish two climatic zones: a) countries with dry climate, temperatures between 40 and 46/sup 0/C/19% R.H. in summer and 0/sup 0/C/80% R.H. in winter during which water can be used for cooling. b) countries with humid climate, temperatures between 38 and 40/sup 0/C/55% R.H. in summer and -12/sup 0/C/85% R.H. in winter during which water for cooling would be available, but can not be used for physical reasons. The first group includes Syria, large parts of Iraq (excluding the South, Amman-Basrah region), the interior parts of Saudi-Arabia, the second South Iraq, Kuwait, the Gulf States and the coast districts of Saudi-Arabia. This arrangement appears to be significant, because from it emerges the distinct equipment of the air conditioning installations and the problems which arise there from.

    Velocity skin effect is a principle reason that solid armatures in railguns transition from smooth metal-on-metal contact with the rails to arcing contact. Transition occurs when armature velocity reaches some critical value which depends weakly on current and strongly on the latent heat of evaporation and electrical conductivity of the armature material. Conductivity of the rail material is also a factor. The analysis shows that when current is fed to the armature from the muzzle of a railgun armature to rail current distribution is more uniform over the contact face than is the case with normal breech feed. The authors show that muzzle feed allows transition velocity to be increased three-fold

    Nondestructive testing (NDT) plays a critical role in maintaining quality and guaranteeing the safety of industries by predicting or assessing the performance and service life of a structure throughout its lifecycle, from manufacturing to operation and maintenance. The ability to assess the integrity of a material, component or structure without affecting its useful life provides perfect balance between quality control and cost-effectiveness. NDT is also used for equipment life assessment or condition assessment to estimate the operational life of plant components, such as processing lines, pipes, tanks and pressure vessels, etc. Based on this information, strategic plans can be developed for extending the useful life of these components. There are more than 60 techniques for performing NDT, with newer techniques being developed at a rapid pace. However, based on the item being inspected, these techniques can be broadly classified into two categories: surface inspection and volumetric inspection. Techniques like dye penetrant testing, magnetic testing, and eddy current testing are classified under surface inspection, with radiography, ultrasonic testing, and acoustic emission classified under volumetric inspection. The traditional or conventional NDT techniques, such as magnetic particle inspection, penetrant testing, radiography and ultrasonic testing, have been around for nearly a century. However, these and the other technologies have evolved significantly since their inception, with newer advanced techniques developed over the past two decades. Amongst the most notable advancements in technology include phased array ultrasonic testing and digital radiography. In an industry where adoption of new technology is a key challenge, the success phased array and digital radiography have achieved as mainstream inspection techniques is noteworthy. (author)

    2018-02-17

    The future of the pharmacy profession and concerns about professional identity have been popular and recurring themes in professional journals and at international pharmacy conferences for more than 30 years. The aim of this paper is to contribute to realistic and viable visions for the future of the pharmacy profession via insights through labor market and work organization theories. These insights provide an understanding of contemporary work patterns and what they mean for the future role of community pharmacists. It appears that an important and influential contemporary trend in work organization today is precarious work, i.e. non-standard employment that promotes and relies on a flexible and fluid work force. Contrary to permanent employment, precarious work is often poorly paid, insecure, unprotected, and in many cases cannot support a household. The growth of precarious work among professionals, including pharmacists has been documented in many countries. In the early 21st century a major concern in the UK was the growth in the number of pharmacists who choose to be self-employed "locums" as opposed to seeking permanent employment. With the spread of precarious work a new, involuntary form of employment appeared a decade later with the spread of "zero-hour contracts" and "exclusivity agreements". Particularly affected by these flexible, precarious work conditions are the highly-educated young health professionals such as pharmacists. The profession needs to be proactive in order to stay abreast of economic/workforce and organizational trends. The way forward is a commitment to a dynamic, knowledge-based vision that includes an ongoing analysis of the outside world. The core role of pharmacists in the future includes: 1. engagement in interprofessional education with other healthcare professionals; 2. an acceptance of the contribution that lay knowledge provides to the understanding of health and medicines, and 3.keeping ajour with new and revolutionary

    1994-01-01

    Till recently analysis of vibration signals was the only means available to predict the state of health of plant equipment. Motor current and leakage magnetic flux signature analysis is acquiring importance as a technique for detection of incipient damages in the electrical machines and as a supplementary technique for diagnostics of driven equipment such as centrifugal and reciprocating pumps. The state of health of the driven equipment is assessed by analysing time signal, frequency spectrum and trend analysis. For example, the pump vane frequency, piston stroke frequency, gear frequency and bearing frequencies are indicated in the current and flux spectra. By maintaining a periodic record of the amplitudes of various frequency lines in the frequency spectra, it is possible to understand the trend of deterioration of parts and components of the pump. All problems arising out of inappropriate mechanical alignment of vertical pumps are easily identified by a combined analysis of current, flux and vibration signals. It is found that current signature analysis technique is a sufficient method in itself for the analysis of state of health of reciprocating pumps and compressors. (author). 10 refs., 4 figs

    Wildfires can have an important impact on regional air quality as they are large and intermittent sources of primary particulates, secondary aerosols, and ozone precursors. As part of an ongoing analysis on the effects of global change upon US air quality, we report results for current and future decade simulations of the inter-relationship among climate change, wildfires and air quality. The results are reported for the Northwest, Southwest, and Central Rockies regions of the US. Meteorological fields from the ECHAM5 global climate model for the IPCC A1B scenario were downscaled using the Weather Research Forecast (WRF) model to drive the MEGAN biogenic emissions model, a stochastic fire occurrence model, Fire Simulation Builder (FSB), and the CMAQ chemical transport model to predict ozone and aerosol concentrations. Simulations were completed for two nested domains covering most of the northern hemisphere from eastern Asia to North America at 220 km horizontal resolution (hemispheric domain) and covering the continental US at 36 km resolution (CONUS). Sensitivity studies were conducted for representative summer periods with fire occurrence generated from FSB within the current (1995-2004) and future decade (2045-2054) and using current decade historical fire data obtained from the Bureau of Land Management Database. Results are reported in terms of the effects of global change upon fire occurrence, fire plume transport and PM and ozone pollutant levels.

    Full Text Available This article discusses the results of a study of actual mental state of high school students who are active subjects of career self-determination in terms of interactive learning. There are four groups of methods of interactive training: psychological training, art therapy, cognitive, and game training. The main task, which is solved by a researcher in a formative experiment with the use of each of these methods, is to establish significant differences in health, activity and mood as the indicators of current mental state of students in the classroom. As a result, we found that the most significant improvements in the current mental state takes place when using art and game therapy, so these techniques should be used in groups of students with low motivation to work, as well as in the adverse psychological climate. Less significant was the improvement of the current mental state after psychological training due to the fact that this method allow to update and seek solutions to the most important intrapersonal issues and require the implementation of a deeper reflection

    A new and better taste avoidance conditioning paradigm for Lymnaea has been developed that replaces the previously used tactile unconditional stimulus (US) with an brief electrical stimulus (1000V, 80μA), while continuing to use a sucrose application to the lips as the conditional stimulus (CS). With 15 paired CS-US presentations on a single day, we were able to elicit both short-term memory (STM) and long-term memory (LTM). The LTM persisted for at least one week. While STM was elicited with 5, 8, or 10 paired presentations of the CS-US on a single day, LTM was not. The new US used here was more consistent than the previously used US, and this stimulus consistency may explain why 15 paired CS-US presentations now result in LTM formation.

    Objective The aim of the present study was to audit the current use of medical records to determine completeness and concordance with other sources of medical information. Methods Medical records for 40 patients from each of five Melbourne major metropolitan hospitals were randomly selected (n=200). A quantitative audit was performed for detailed patient information and medical record keeping, as well as data collection, storage and utilisation. Using each hospital's current online clinical database, scanned files and paperwork available for each patient audited, the reviewers sourced as much relevant information as possible within a 30-min time allocation from both the record and the discharge summary. Results Of all medical records audited, 82% contained medical and surgical history, allergy information and patient demographics. All audited discharge summaries lacked at least one of the following: demographics, medication allergies, medical and surgical history, medications and adverse drug event information. Only 49% of records audited showed evidence the discharge summary was sent outside the institution. Conclusions The quality of medical data captured and information management is variable across hospitals. It is recommended that medical history documentation guidelines and standardised discharge summaries be implemented in Australian healthcare services. What is known about this topic? Australia has a complex health system, the government has approved funding to develop a universal online electronic medical record system and is currently trialling this in an opt-out style in the Napean Blue Mountains (NSW) and in Northern Queensland. The system was originally named the personally controlled electronic health record but has since been changed to MyHealth Record (2016). In Victoria, there exists a wide range of electronic health records used to varying degrees, with some hospitals still relying on paper-based records and many using scanned medical records

    It is shown that, if the maximum of the magnetic field strength on a magnetic surface in a threedimensional magnetic confinement configuration with stellarator symmetry constitutes a line that is orthogonal to the field lines and crosses the symmetry line, then the bootstrap current density is smaller compared to that in quasi-axisymmetric (qa) [J.

    Full Text Available This article deals with the verification of relations between the electric current of engine starter and tightness of the combustion chamber and the possibility of its use for the evaluation of the state in terms of engine wear. Engine wear is closely related to the quality of fuel combustion and also with the amount of produced harmful emissions. On this basis, it would be possible to extend the technical requirements of the protocol OBD to include the indirect control of engine wear. To meet the objectives set out above measurement was carried out by a petrol engine, which was located in the vehicle Škoda Felicia Combi GLX 1.3 The whole measurement was divided into several parts. The first measurement was carried out on the abovementioned motor without simulating leakage. The second measurement was performed when the leakage of one cylinder was simulated. Simulated leakage was conducted at removing the spark plugs. Other measurements simulated “mild” leak of the whole engine – all cylinders. Leakage was implemented by loosing all the spark plugs about 8 turns against full tightening with the appropriate torque. The last, fourth measurement simulates a “large” leaks of engine cylinders. This leakage was induced by removing all the spark plugs from all cylinders. As the measurement results showed leakage of one cylinder, and also the whole engine is reflected not only in the individual amplitude of the starter current, but also the shape of the entire curve.

  19. Secondary current properties generated by wind-induced water waves in experimental conditions

    Full Text Available Secondary currents such as the Langmuir circulation are of high interest in natural rivers and the ocean because they have striking impacts on scour, sedimentation, and mass transport. Basic characteristics have been well-studied in straight open-channel flows. However, little is known regarding secondary circulation induced by wind waves. The presented study describes the generation properties of wind waves observed in the laboratory tank. Wind-induced water waves are known to produce large scale circulations. The phenomenon is observed together with high-speed and low-speed streaks, convergence and divergence zones, respectively. Therefore, it is important to determine the hydrodynamic properties of secondary currents for wind-induced water waves within rivers and lakes. In this study, using two high-speed CMOS cameras, stereoscopic particle image velocimetry (PIV measurements were conducted in order to reveal the distribution of all three components of velocity vectors. The experiments allowed us to investigate the three-dimensional turbulent structure under water waves and the generation mechanism of large-scale circulations. Additionally, a third CMOS camera was used to measure the spanwise profile of thefree-surface elevation. The time-series of velocity components and the free-surface were obtained simultaneously. From our experiments, free-surface variations were found to influence the instantaneous velocity distributions of the cross-sectional plane. We also considered thegeneration process by the phase analysis related to gravity waves and compared the contribution of the apparent stress.

    2009-12-01

    The foundation of an integrated pest management program involves valid treatment thresholds, accurate and simple monitoring methods, effective natural controls, selective pesticides and trained individuals who can implement the concept. The Integrated Control Concept written by Stern, Smith, van den Bosch and Hagen elucidated each of these points in an alfalfa ecosystem. Alfalfa hay (Medicago sativa L.) has a low per acre value, requires little hand labor and is primarily marketed in the USA. In contrast, fresh market table grape (Vitis vinifera L.) has a high per acre value, requires frequent hand labor operations, suffers unacceptable cosmetic damage and is marketed throughout both the USA and the world. Each of the components of a working IPM program is present in table grape production. Marketing grapes to foreign countries presents special problems with pests considered invasive and where residue tolerances for some selective insecticides are lacking. However, fresh market grape farmers are still able to deal with these special problems and utilize an IPM program that has resulted in a 42% reduction in broad-spectrum insecticide use from 1995 to 2007.

    We applied a 1-dimensional lake model developed to simulate deep mixing related to thermobaric instabilities in temperate lakes to Crater Lake, a 590-m deep caldera lake in Oregon's Cascade Range known for its stunning deep blue color and extremely clear water, in order to determine the frequency of deep water renewal in future climate conditions. The lake model was calibrated with 6 years of water temperature profiles, and then simulated 10 years of validation data with an RMSE ranging from 0.81°C at 50 m depth to 0.04°C at 350-460 m depth. The simulated time series of heat content in the deep lake accurately captured extreme years characterized by weak and strong deep water renewal. The lake model uses wind speed and lake surface temperature (LST) as boundary conditions. LST projections under six climate scenarios from the CMIP5 intermodel comparison project (2 representative concentration pathways X 3 general circulation models) were evaluated with air2water, a simple lumped model that only requires daily values of downscaled air temperature. air2water was calibrated with data from 1993-2011, resulting in a RMSE between simulated and observed daily LST values of 0.68°C. All future climate scenarios project increased water temperature throughout the water column and a substantive reduction in the frequency of deepwater renewal events. The least extreme scenario (CNRM-CM5, RCP4.5) projects the frequency of deepwater renewal events to decrease from about 1 in 2 years in the present to about 1 in 3 years by 2100. The most extreme scenario (HadGEM2-ES, RCP8.5) projects the frequency of deepwater renewal events to be less than 1 in 7 years by 2100 and lake surface temperatures never cooling to less than 4°C after 2050. In all RCP4.5 simulations the temperature of the entire water column is greater than 4°C for increasing periods of time. In the RCP8.5 simulations, the temperature of the entire water column is greater than 4°C year round by the year 2060 (HadGEM2

    Compulsive buying is characterized by frequent excessive purchasing of items that are primarily not needed or used. The compulsive buying behavior results in mental, social, financial and often legal problems. Although compulsive buying affects a significant percentage of the general population and has received increasing attention in research, it has largely been ignored in clinical practice. Compulsive buying disorder is currently conceptualized as an"impulse control disorder not otherwise specified". However, the appropriate classification continues to be debated. Compulsive buying is associated with significant psychiatric co-morbidity, especially with depressive, anxiety, obsessive-compulsive, substance use, personality, and other impulse control disorders. Small controlled trials failed to confirm the efficacy of antidepressants in the treatment of compulsive buying disorder, whereas early evidence suggests that cognitive behavioral therapy is helpful in alleviating compulsive buying symptoms. Further research is needed to establish a better understanding of etiology, classification, and treatment strategies.

  5. Plasma conditions for non-Maxwellian electron distributions in high current discharges and laser-produced plasmas

    Results from the standard quasilinear theory of ion-acoustic and Langmuir plasma microturbulence are incorporated into the kinetic theory of the electron distribution function. The theory is then applied to high current discharges and laser-produced plasmas, where either the current flow or the nonlinear laser-light absorption acts, respectively, as the energy source for the microturbulence. More specifically, the theory is applied to a selenium plasma, whose charge state is determined under conditions of collisional-radiative equilibrium, and plasma conditions are found under which microturbulence strongly influences the electron kinetics. In selenium, we show that this influence extends over a wide range of plasma conditions. For ion-acoustic turbulence, a criterion is derived, analogous to one previously obtained for laser heated plasmas, that predicts when Ohmic heating dominates over electron-electron collisions. This dominance leads to the generation of electron distributions with reduced high-energy tails relative to a Maxwellian distribution of the same temperature. Ion-acoustic turbulence lowers the current requirements needed to generate these distributions. When the laser heating criterion is rederived with ion-acoustic turbulence included in the theory, a similar reduction in the laser intensity needed to produce non-Maxwellian distributions is found. Thus we show that ion-acoustic turbulence uniformly (i.e., by the same numerical factor) reduces the electrical and heat conductivities, as well as the current (squared) and laser intensity levels needed to drive the plasma into non-Maxwellian states

    Utility load management programs, including direct load control and interruptible load programs, constitute a large installed base of controllable loads that are employed by utilities as system reliability resources. In response to energy supply shortfalls expected during the summer of 2001, the California Public Utilities Commission in spring 2001 authorized new utility load management programs as well as revisions to existing programs. This report provides an independent review of the designs of these new programs for a large utility (Southern California Edison) and suggests possible improvements to enhance the price responsiveness of the customer actions influenced by these programs. The report also proposes a new program to elicit a mass-market demand response to utility price signals.

    Experimental date from low-energy nuclear reactions (LENR) in condensed media are presented. The nuclear reactions products were found in solid cathode media used in glow discharge. Apparently, the nuclear reactions were initiated when bombarding the cathode surface by plasma ions with the energy of 1.0 - 2.0 keV. Excess heat from a high current glow discharge reaction in D{sub 2}, Xe, and Kr using cathodes already charged with preliminary deuterium-charged Pd and Ti cathode samples are given. Excess heat up to 10-15 W and efficiency up to 130% were recorded under the experiments for Pd cathode samples in D{sub 2} discharge. Excess heat up to 5 W and efficiency up to 150% were recorded for Pd cathodes that were charged with deuterium before the run, in Xe and Kr discharges. At the same time excess heat was not observed for pure Pd cathode samples in Xe and Kr discharges.

The isotopic ratios of these new nuclides were quite different from the natural ratios. Soft X-ray radiation from the solid-state cathode with the intensity up to 0.01 Gy/s was recorded in experiments with discharges in H{sub 2}, D{sub 2}, Ar, Xe, and Kr. The X-ray radiation was observed in bursts of up to 10{sup 6} photons, with up to 10{sup 5} bursts per second while the discharge was formed and within 100 ms after turning off the discharge current. The results of the X-ray radiation registration showed that the excited energy levels have a lifetime up to 100 ms or more, and the energy of 1.2 - 2.5 keV. A possible mechanism for producing excess heat and nuclear transmutation reactions in the solid medium with the excited energy levels is considered.

    This work introduces an inductive energy storage (IES) scheme which aims pulsed-power conditioning at multi- MJ energies. The key element of the scheme represents an additional plasma volume, where a magnetically accelerated wire array is used for inductive current switching. This plasma acceleration volume is connected in parallel to a microsecond capacitor bank and to a 100-ns current ruse-time useful load. Simple estimates suggest that optimized scheme parameters could be reachable even when operating at ultra-high currents. We describe first proof-of-principle experiments carried out on GIT12 generator at the wire-array current level of 2 MA. The obtained confirmation of the concept consists in generation of a 200 kV voltage directly at an inductive load. This load voltage value can be already sufficient to transfer the available magnetic energy into kinetic energy of a liner at this current level. Two-dimensional modeling with the radiational MHD numerical tool Marple confirms the development of inductive voltage in the system. However, the average voltage increase is accompanied by short-duration voltage drops due to interception of the current by the low-density upstream plasma. Upon our viewpoint, this instability of the current distribution represents the main physical limitation to the scheme performance

    2012-01-01

    This study uses microeconomic data from the transportation systems of land cargo in Colombia: rail and trucking, to determine their degree of allocative efficiency through the non-parametric method Data Envelopment Analysis DEA. The average overall efficiency found was 74.4% for trains and 20.56% for trucks. These figures indicate that rail is more efficient in the allocation of resources. This means that trains in Colombia use their input better than trucks to maximize their production, given the costs and technological characteristics of each system. This is a signal for the design of a public policy for investment in transportation infrastructure that seeks to raise the competitiveness of Colombian exports, investing not only in roads but in complementary systems such as railways too. - Highlights: ► Colombia is currently undergoing a backlog of transport infrastructure and high export costs. ► We perform a microeconomic study of transportation systems in Colombia: rail and trucking. ► As a result we found that the rail is much more efficient than the automotive system. ► As policy recommendation the government should consider the investment in railways. ► It is necessary to take into account the strategic value that investment in railways would bring.

    Condition monitoring of rotating machine is essential to guarantee the safety operation as well as to improve the efficiency of nuclear power plants operations. One of the promising condition monitoring techniques which has been preferred currently since it is simple, non-invasive and inexpensive is Motor Stator Signature Analysis (MCSA). However, the investigation of the MCSA technique using a compact, low cost, and having industrial class hardware which is capable for nuclear power plant applications has been limited. The research is aimed to develop condition monitoring method based on MCSA utilizing a compact industrial class for nuclear power plant. The investigation includes development of condition monitoring based on real-time FPGA-CompatRIO hardware, development of a custom built display module for early warning system, testing of the monitoring hardware, fault frequency analysis of electric motors including the performances of fault detections. The condition monitoring system is able to execute a fault detection task around 164 ms, to recognize accurately fault frequencies of stator shorted turn for about 75%, broken rotor bar around 95%, eccentricity 65%, mechanical misalignment 85%, including supply voltage unbalances 100%. The condition monitoring system based on its performance assessments could become a suitable alternative not only for rotating machines but also condition monitoring for other nuclear reactor components.

  14. Leakage current characterization for estimating the conditions of non-ceramic insulators' surfaces

    2007-03-15

    In this work both detection of the beginning of dry-band arcing and correlating the average value of leakage current (LC) with non-ceramic insulator surface damage have been investigated. Silicone rubber insulators were tested in salt-fog under different voltage and conductivity levels. The autocorrelation function (ACF) was calculated for both the fundamental and third harmonic components of LC during the early aging period (EAP). It has been observed that distinct differences exist in the behavior of both the fundamental and that of the third harmonic components of the LC during EAP. Although the fundamental component of the LC begins to grow immediately after starting the test, the third harmonic requires a much longer period of time to begin. Dry-band arcing is highly correlated with distortion in the LC and hence to its third harmonic component. But it has been observed that the level of the fundamental component of LC at which the third harmonic component started to increase is different from one case to another. As such, it is more appropriate to use the ACF of the third harmonic component of LC as an indication of dry-band arcing rather than a simple threshold value. Moreover, the average value of LC during late aging period (LAP) was correlated with the damage of non-ceramic insulators. It has been found that the average level of both the fundamental and third harmonic component of LC is well correlated with the different degrees of damage of non-ceramic insulators' surface.

    Efficacy of four commercial biocidal products (noted A to D), using manufacturers' recommendations, and a contact time of 30minutes, were evaluated in the purpose of standard SR EN1657: 2006 adapted. Were used four strains, two as reference: Aspergillus brasiliensis (niger) (ATCC 16404) and Candida albicans (ATCC 10231), and two isolates: Aspergillus flavus and respectively Aspergillus fumigatus. The inoculum plates containing Malt Extract Agar (MEA) were incubated 48h for C. albicans and 72hours for Aspergillus spp. The standard SR EN1657: 2006 adapted was conducted in two phases: the test cultures preparation and the method validation. Method validation included: the control of experimental conditions and of neutralizant solution, and the method verification. Results revealed that three from the four tested products (A, B and D) had exerted biocidal effect on the studied strains at the recommended concentrations, the registered CFU values being reduced by more than 4 log 10 , conversely in the case of the product (C), applied against A. fumigatus at the recommended concentration of 2%, the biocidal effect was not detected, fact confirmed also by the CFU's value (3.59 log 10 ). The biocide retested at a greater concentration (of 5%), showed a biocidal effect against A. fumigatus after 30minutes, the CFU value being reduced, by more than 5.29 log 10 , evidencing the resistance emergence of A. fumigatus under the repeated pressure of biocides. It is re-confirming that merely the "chemical" defense measures to defuse the fungi's strategies become unproductive. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  17. Groundwater resources of the Devils Postpile National Monument—Current conditions and future vulnerabilities

    2017-06-15

    This study presents an extensive database on groundwater conditions in and around Devils Postpile National Monument. The database contains chemical analyses of springs and the monument water-supply well, including major-ion chemistry, trace element chemistry, and the first information on a list of organic compounds known as emerging contaminants. Diurnal, seasonal, and annual variations in groundwater discharge and chemistry are evaluated from data collected at five main monitoring sites, where streams carry the aggregate flow from entire groups of springs. These springs drain the Mammoth Mountain area and, during the fall months, contribute a significant fraction of the San Joaquin River flow within the monument. The period of this study, from fall 2012 to fall 2015, includes some of the driest years on record, though the seasonal variability observed in 2013 might have been near normal. The spring-fed streams generally flowed at rates well below those observed during a sequence of wet years in the late 1990s. However, persistence of flow and reasonably stable water chemistry through the recent dry years are indicative of a sizeable groundwater system that should provide a reliable resource during similar droughts in the future. Only a few emerging contaminants were detected at trace levels below 1 microgram per liter (μg/L), suggesting that local human visitation is not degrading groundwater quality. No indication of salt from the ski area on the north side of Mammoth Mountain could be found in any of the groundwaters. Chemical data instead show that natural mineral water, such as that discharged from local soda springs, is the main source of anomalous chloride in the monument supply well and in the San Joaquin River. The results of the study are used to develop a set of recommendations for future monitoring to enable detection of deleterious impacts to groundwater quality and quantity

  20. A global assessment of gross and net land change dynamics for current conditions and future scenarios

    The consideration of gross land changes, meaning all area gains and losses within a pixel or administrative unit (e.g. country), plays an essential role in the estimation of total land changes. Gross land changes affect the magnitude of total land changes, which feeds back to the attribution of biogeochemical and biophysical processes related to climate change in Earth system models. Global empirical studies on gross land changes are currently lacking. Whilst the relevance of gross changes for global change has been indicated in the literature, it is not accounted for in future land change scenarios. In this study, we extract gross and net land change dynamics from large-scale and high-resolution (30-100 m) remote sensing products to create a new global gross and net change dataset. Subsequently, we developed an approach to integrate our empirically derived gross and net changes with the results of future simulation models by accounting for the gross and net change addressed by the land use model and the gross and net change that is below the resolution of modelling. Based on our empirical data, we found that gross land change within 0.5° grid cells was substantially larger than net changes in all parts of the world. As 0.5° grid cells are a standard resolution of Earth system models, this leads to an underestimation of the amount of change. This finding contradicts earlier studies, which assumed gross land changes to appear in shifting cultivation areas only. Applied in a future scenario, the consideration of gross land changes led to approximately 50 % more land changes globally compared to a net land change representation. Gross land changes were most important in heterogeneous land systems with multiple land uses (e.g. shifting cultivation, smallholder farming, and agro-forestry systems). Moreover, the importance of gross changes decreased over time due to further polarization and intensification of land use. Our results serve as an empirical database for

    A MFC-based biosensor can act as online toxicity sensor. Electrical current is a direct linear measure for metabolic activity of electrochemically active microorganisms. Microorganisms gain energy from anodic overpotential and current strongly depends on anodic overpotential. Therefore control of anodic overpotential is necessary to detect toxic events and prevent false positive alarms. Anodic overpotential and thus current is influenced by anode potential, pH, substrate and bicarbonate concentrations. In terms of overpotential all factor showed a comparable effect, anode potential 1.2% change in current density per mV, pH 0.43%/mV, bicarbonate 0.75%/mV and acetate 0.8%/mV. At acetate saturation the maximum acetate conversion rate is reached and with that a constant bicarbonate concentration. Control of acetate and bicarbonate concentration can be less strict than control of anode potential and pH. Current density changes due to changing anode potential and pH are in the same order of magnitude as changes due to toxicity. Strict control of pH and anode potential in a small range is required. The importance of anodic overpotential control for detection of toxic compounds is shown. To reach a stable baseline current under nontoxic conditions a MFC-based biosensor should be operated at controlled anode potential, controlled pH and saturated substrate concentrations. 2009 Elsevier B.V.

    The National Electrostatics Corporation's (NEC) Toroidal Volume Ion Source (TORVIS) source is known for exceptionally high proton currents with minimal service downtime as compared to traditional sputter sources. It has been possible to obtain over 150{mu}A of proton current from the source, with over 70{mu}A on the target stage. However, beam fluxes above {approx}1 Multiplication-Sign 10{sup 17}/m2-s may have many undesirable effects, especially for insulators. This may include high temperature gradients at the surface, sputtering, surface discharge, cracking or even disintegration of the sample. A series of experiments were conducted to examine the role of high current fluxes in a suite of ceramics and insulating materials. Results will show the optimal proton irradiation conditions and target mounting strategies needed to minimize unwanted macro-scale damage, while developing a procedure for conducting preliminary radiation experiments.

    The uranium market still retains arrangements developed in the mists of time, but now is an appropriate time for something new to be developed. Quoted uranium prices continue to move sharply upwards. It can be argued that the long period of price depression followed by such a dramatic spike indicates that the uranium market is not functioning as it really should. Nevertheless, the particular characteristics of the uranium business should ensure that it should arguably have much calmer market conditions. Much of the problem relates to lack of market liquidity and transparency. Prices are published on a weekly and monthly basis by informed observers and are based on information they glean from market participants.The infrastructure issue of much of the nuclear fuel supply business is slowly but surely getting addressed by the required new investment, but the uranium market is still in need of something new.The question then remains about the longer-term market. To some extent, having a more transparent and liquid spot market will go some way towards addressing this. It will undoubtedly take some entrepreneurial leadership to induce this to happen, plus realisation that the current marketplace cannot be in the long-term interest of either buyers or sellers.

  7. Automatic Condition Monitoring of Industrial Rolling-Element Bearings Using Motor’s Vibration and Current Analysis

    Full Text Available An automatic condition monitoring for a class of industrial rolling-element bearings is developed based on the vibration as well as stator current analysis. The considered fault scenarios include a single-point defect, multiple-point defects, and a type of distributed defect. Motivated by the potential commercialization, the developed system is promoted mainly using off-the-shelf techniques, that is, the high-frequency resonance technique with envelope detection and the average of short-time Fourier transform. In order to test the flexibility and robustness, the monitoring performance is extensively studied under diverse operating conditions: different sensor locations, motor speeds, loading conditions, and data samples from different time segments. The experimental results showed the powerful capability of vibration analysis in the bearing point defect fault diagnosis. The current analysis also showed a moderate capability in diagnosis of point defect faults depending on the type of fault, severity of the fault, and the operational condition. The temporal feature indicated a feasibility to detect generalized roughness fault. The practical issues, such as deviations of predicted characteristic frequencies, sideband effects, time-average of spectra, and selection of fault index and thresholds, are also discussed. The experimental work shows a huge potential to use some simple methods for successful diagnosis of industrial bearing systems.

    Development and optimisation of alternative strategies to reduce the use of classic chemical inputs for protection against diseases in vineyard is becoming a necessity. Among these strategies, one of the most promising consists in the stimulation and/or potentiation of the grapevine defence responses by the means of elicitors. Elicitors are highly diverse molecules both in nature and origins. This review aims at providing an overview of the current knowledge on these molecules and will highlight their potential efficacy from the laboratory in controlled conditions to vineyards. Recent findings and concepts (especially on plant innate immunity) and the new terminology (microbe-associated molecular patterns, effectors, etc.) are also discussed in this context. Other objectives of this review are to highlight the difficulty of transferring elicitors use and results from the controlled conditions to the vineyard, to determine their practical and effective use in viticulture and to propose ideas for improving their efficacy in non-controlled conditions.

    Highlights: • Heavy metals in spent compact fluorescent lamps (CFLs) determined. • Current waste management condition of CFLs in Iran assessed. • Currently, waste of CFLs is disposed by municipal waste stream in waste landfills. • We propose extended producer responsibility (EPR) for CFLs waste management. - Abstract: From environmental viewpoint, the most important advantage of compact fluorescent lamps (CFLs) is reduction of green house gas emissions. But their significant disadvantage is disposal of spent lamps because of containing a few milligrams of toxic metals, especially mercury and lead. For a successful implementation of any waste management plan, availability of sufficient and accurate information on quantities and compositions of the generated waste and current management conditions is a fundamental prerequisite. In this study, CFLs were selected among 20 different brands in Iran. Content of heavy metals including mercury, lead, nickel, arsenic and chromium was determined by inductive coupled plasma (ICP). Two cities, Tehran and Tabriz, were selected for assessing the current waste management condition of CFLs. The study found that waste generation amount of CFLs in the country was about 159.80, 183.82 and 153.75 million per year in 2010, 2011 and 2012, respectively. Waste generation rate of CFLs in Iran was determined to be 2.05 per person in 2012. The average amount of mercury, lead, nickel, arsenic and chromium was 0.417, 2.33, 0.064, 0.056 and 0.012 mg per lamp, respectively.

    Injection current dependences of electroluminescence transition energy in blue InGaN/GaN multiple quantum wells light emitting diodes (LEDs) with different quantum barrier thicknesses under pulsed current conditions have been analyzed taking into account the related effects including deformation caused by lattice strain, quantum confined Stark effects due to polarization field partly screened by carriers, band gap renormalization, Stokes-like shift due to compositional fluctuations which are supposed to be random alloy fluctuations in the sub-nanometer scale, band filling effect (Burstein-Moss shift), and quantum levels in finite triangular wells. The bandgap renormalization and band filling effect occurring at high concentrations oppose one another, however, the renormalization effect dominates in the concentration range studied, since the band filling effect arising from the filling in the tail states in the valence band of quantum wells is much smaller than the case in the bulk materials. In order to correlate the carrier densities with current densities, the nonradiative recombination rates were deduced experimentally by curve-fitting to the external quantum efficiencies. The transition energies in LEDs both with 15 nm quantum barriers and 5 nm quantum barriers, calculated using full strengths of theoretical macroscopic polarization given by Barnardini and Fiorentini [Phys. Status Solidi B 216, 391 (1999)] are in excellent accordance with experimental results. The LED with 5 nm barriers has been shown to exhibit a higher transition energy and a smaller blue shift than those of LED with 15 nm barriers, which is mainly caused by the smaller internal polarization field in the quantum wells.

    2015-07-08

    Drug-induced liver injury (DILI) and herb-induced liver injury is a hot topic for clinicians, academia, drug companies and regulators, as shown by the steadily increasing number of publications in the past 15 years. This review will first provide clues for clinicians to suspect idiosyncratic (unpredictable) DILI and succeed in diagnosis. Causality assessment remains challenging and requires careful medical history as well as awareness of multifaceted aspects, especially for herbs. Drug discontinuation and therapy reconciliation remain the mainstay in patent's management to minimize occurrence of acute liver failure. The second section will address novel agents associated with liver injury in 2014 (referred to as "signals"), especially in terms of clinical, research and drug development implications. Insights will be provided into recent trends by highlighting the contribution of different post-marketing data, especially registries and spontaneous reporting systems. This literature scrutiny suggests: (1) the importance of post-marketing databases as tools of clinical evidence to detect signals of DILI risk; and (2) the need for joining efforts in improving predictivity of pre-clinical assays, continuing post-marketing surveillance and design ad hoc post-authorization safety studies. In this context, ongoing European/United States research consortia and novel pharmaco-epidemiological tools (e.g., specialist prescription event monitoring) will support innovation in this field. Direct oral anticoagulants and herbal/dietary supplements appear as key research priorities.

    Educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. This study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students' viewpoint and ultimately increase the awareness and understanding of authorities and educational planners of the existing shortcomings.  This is a descriptive-analytical study. Samples include all nursing, operating room, and anesthesia students of nursing and paramedical college who had passed at least 5 semesters. Data collection was carried out through a scholar questionnaire. Validity was assessed through content validity and reliability of the questionnaire was evaluated using a pilot study.  In order to determine the status of the scores, 5 points (very high), 4 (often), 3 (moderate), 2 (low) and 1 (very low) were assigned, respectively. To determine the justice level, a 35 score interval was considered as very low, low, medium, high and very high. SPSS software, descriptive statistics, independent t-test and ANOVA were used to analyze the data.  There was a significant difference between the ideal and the current conditions in all items (p≤0.001) and also in the total mean score of ideal condition  and mean score of current condition (p=0.010). In an educational system, educational methods and aims should be regulated in a way that principles and components of justice are attainable and distribution and allocation of educational facilities of justice are considered thoroughly.

    The decision to breed influences an individual's current and future reproduction, and the proportion of individuals that breed is an important determinant of population dynamics. Age, experience, individual quality, and environmental conditions have all been demonstrated to influence breeding propensity. To elucidate which of these factors exerts the greatest influence on breeding propensity in a temperate waterfowl, we studied female Lesser Scaup (Aythya affinis) breeding in southwestern Montana. Females were captured during the breeding seasons of 2007–2009, and breeding status was determined on the basis of (1) presence of an egg in the oviduct or (2) blood plasma vitellogenin (VTG) levels. Presence on the study site in the previous year, a proxy for adult female success, was determined with stable isotope signatures of a primary feather collected at capture. Overall, 57% of females had evidence of breeding at the time of capture; this increased to 86% for females captured on or after peak nest initiation. Capture date and size-adjusted body condition positively influenced breeding propensity, with a declining body-condition threshold through the breeding season. We did not detect an influence of age on breeding propensity. Drought conditions negatively affected breeding propensity, reducing the proportion of breeding females to 0.85 (SE = 0.05) from 0.94 (SE = 0.03) during normal-water years. A female that was present in the previous breeding season was 5% more likely to breed than a female that was not present then. The positive correlation between age and experience makes it difficult to differentiate the roles of age, experience, and individual quality in reproductive success in vertebrates. Our results indicate that individual quality, as expressed by previous success and current body condition, may be among the most important determinants of breeding propensity in female Lesser Scaup, providing further support for the individual heterogeneity hypothesis.

    Full Text Available Under conditions of intensive strengthening of globalization of world financial markets and deepening of the crisis, the main source of which are financial markets, financial derivatives market is rapidly developing. In such circumstances, we observe very active growing demand for tools, the main purpose of which is to reduce the financial risk – derivatives. Outlined trend has also involved Ukraine. In this connection, there is an objective need to develop estimate the interconnection of the money and stock markets and derivatives market. It should be kept in mind that achieving the outlined goal is possible only under condition of the full understanding of the scientific and methodological principles of the development of these markets. Purpose is to estimate the interconnection of the money and stock markets and derivatives market by building a mathematical model of system of structural equations that will promote the compilation of scientifically based program of derivatives market. Methodology. By using methods of economic-mathematical modelling were estimated the degree of influence of studied markets factors on financial derivatives market development and by changing this or that factor were predicted future trends of its operations. Results of the survey showed the current state and problems of derivatives market functioning. At the same time, our study allowed us to talk, that factors of the money and stock markets have a different impact on the derivatives market. So, the majority of money market factors have a reverse influence on the development of derivatives market. Instead, the stock market has a direct influence. Practical implications. The proposed scientific and methodical approach to evaluating the impact of factors on the derivatives market allows: influenced by different factors; to conduct a qualitative interpretation of the quantitative changes in the level of market development; to form a complete system of state

    Chlamydia trachomatis is one of the most frequently reported sexually transmitted infections (STI) in Australia, the UK and Europe. Yet, rates of screening for STIs remain low, especially in younger adults. To assess effectiveness of Chlamydia screening interventions targeting young adults in community-based settings, describe strategies utilized and assess them according to social marketing benchmark criteria. A systematic review of relevant literature between 2002 and 2012 in Medline, Web of Knowledge, PubMed, Scopus and the Cumulative Index to Nursing and Allied Health was undertaken. Of 18 interventions identified, quality of evidence was low. Proportional screening rates varied, ranging from: 30.9 to 62.5% in educational settings (n = 4), 4.8 to 63% in media settings (n = 6) and from 5.7 to 44.5% in other settings (n = 7). Assessment against benchmark criteria found that interventions incorporating social marketing principles were more likely to achieve positive results, yet few did this comprehensively. Most demonstrated customer orientation and addressed barriers to presenting to a clinic for screening. Only one addressed barriers to presenting for treatment after a positive result. Promotional messages typically focused on providing facts and accessing a testing kit. Risk assessment tools appeared to promote screening among higher risk groups. Few evaluated treatment rates following positive results; therefore, impact of screening on treatment rates remains unknown. Future interventions should consider utilizing a comprehensive social marketing approach, using formative research to increase insight and segmentation and tailoring of screening interventions. Easy community access to both screening and treatment should be prioritized. © 2015 John Wiley & Sons Ltd.

The authors contend that their findings in this paper question the status quo of promising business scopes for companies in the U.S. market.

  2. Market Power in Laboratory Emission Permit Markets

    Godby, R.

    2002-01-01

    Many proposals suggesting the use of markets to control pollution assume markets will be competitive. When markets do not exhibit competitive characteristics, however, should they still be expected to result in efficiency improvement relative to traditional approaches? This paper employs experimental economic methods to examine the effect of market structure on the use of marketable emissions permits. Results indicate that in a market with one dominant firm and a number of fringe firms, strategic manipulation occurs repeatedly in the laboratory as predicted by market power models, undermining the allocative and dynamic efficiency benefits such markets offer. When firms compete in a downstream product market dominated by the same single firm, market efficiency can actually be reduced with the implementation of permit markets. Final market efficiencies reflect initial endowments and are influenced by competitive conditions elsewhere in the economy, indicating that policy-makers should carefully consider whether markets are appropriate in such circumstances

  3. Market power monitoring and mitigation in the US wholesale power markets

    Energy Technology Data Exchange (ETDEWEB)

    Helman, Udi [Federal Energy Regulatory Commission, 888 First Street, N.E., Washington, DC 20426 (United States)

    2006-05-15

    Under current statutory requirements, the Federal Energy Regulatory Commission (FERC) must ensure that prices in US wholesale power markets are 'just and reasonable'. This has been interpreted by the agency and the courts as requiring the monitoring and mitigation of undue market power. This paper focuses on generation market power. Prior to electricity sector restructuring, wholesale bilateral power trading took place among vertically integrated monopoly utilities trading at the margin or between small independent producers and the utilities. Under those conditions, the authorization of trading at market prices, called 'market-based rates', required only that the generation supplier pass a simple market share screen for market power. As restructuring unfolded, and market conditions changed, there has been a steady evolution in FERC's market power mitigation rules, encompassing (a) changes in the market power assessment required for granting market-based rates and related methods for merger approval, and (b) development and refinement of new techniques for screening and mitigating offers into the organized day-ahead and real-time markets operated by Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs). This paper reviews these changes to date, as FERC continues to clarify its approved rules and procedures. It also examines recent methods for quantitative market power analysis that could augment current procedures or supplant them, as found appropriate. (author)

    2014-06-01

    Full Text Available Background: Entering employment and achieving a stable position in the labour market are considered important preconditions for childbearing. Existing studies addressing the relationship between work experience and the timing of parenthood focus exclusively on Western Europe and North America. By adding an Eastern European context before and after societal transformation, this study contributes to a more comprehensive account of the role of work experience in first-birth timing in Europe. Objective: We investigate how work experience and career development are related to the timing of parenthood in two diverse contexts in Estonia, state socialism and the market economy, and how it varies by gender and nativity. Methods: The data used come from the Estonian Health Interview Survey 2006-2007. We estimate piecewise constant event history models to analyse the transition to first birth. Results: Our results suggest that in the market economy work experience became moreimportant in the decision to enter parenthood. In the market economy the importance of work experience to entering parenthood became more similar for women and men. Non-native-origin men and women's timing of parenthood appears to have become detached from their career developments. The article discusses mechanisms that may underlie the observed patterns. Conclusions: Our study shows how work experience gained importance as a precondition for parenthood in the transition to a market economy. This lends support to the view that the increasing importance of work experience is among plausible drivers of the postponement transition that extended to Eastern Europe in the 1990s.

  6. Proposed Industry Best Practices in Development and Marketing of Medical Foods for the Management of Chronic Conditions and Diseases while Awaiting Regulation.

    Science.gov (United States)

    Burnett, Bruce; Levy, Robert M

    Ideal therapeutics have low toxicity and can effectively manage condition(s) or disease(s). The Food & Drug Administration (FDA) marketing category of therapeutics called “medical foods” (MFs) meets such a definition. Medical foods have existed in Federal law since passage the Orphan Drug Act in 1988, which created a category of nutritional therapeutics separate from drugs. Unfortunately, MFs are not widely understood by the medical community or utilized in all patients who need them due to lack of a FDA-approval process, unclear and contradictory guidance especially with regard for need for an investigational new drug (IND) application, and no clear regulations regarding their development and marketing. The goals of this article are to propose “Best Practices” to guide the medical food industry in the development and marketing of products as well as to serve as a starting point for suggestions regarding further FDA regulation so that therapeutics which are shown to be generally recognized as safe (GRAS), provide food ingredients to meet a distinctive nutritional requirement for a specific condition/disease and are proven effective for the management for that condition/disease can be used to benefit patients who need them.

    Full Text Available Providing small and medium enterprises (SMEs with access to external finance has been a major concern for many governments and international organizations for three decades. In recent years the experiences of emerging market countries suggest that a paradigm shift is taking place in SME finance. Particularly in fast-growing emerging market countries such as Turkey, banks are increasingly targeting SMEs as a new line of banking business. This research analyzes how macroeconomic factors have contributed to increased commercial bank lending to SMEs in six emerging market countries: Turkey, Argentina, Brazil, Mexico, Chile, and Poland. Based on time series and panel data analysis, we find that a high GDP growth rate and increased competition in the banking sector have contributed to increased banking sector credit to SMEs. The findings also reveal that curbing the high inflation rate and reducing government domestic borrowing have significantly encouraged bank lending to the SME segment.

  8. Impact of urban WWTP and CSO fluxes on river peak flow extremes under current and future climate conditions.

    2013-01-01

    The impact of urban water fluxes on the river system outflow of the Grote Nete catchment (Belgium) was studied. First the impact of the Waste Water Treatment Plant (WWTP) and the Combined Sewer Overflow (CSO) outflows on the river system for the current climatic conditions was determined by simulating the urban fluxes as point sources in a detailed, hydrodynamic river model. Comparison was made of the simulation results on peak flow extremes with and without the urban point sources. In a second step, the impact of climate change scenarios on the urban fluxes and the consequent impacts on the river flow extremes were studied. It is shown that the change in the 10-year return period hourly peak flow discharge due to climate change (-14% to +45%) was in the same order of magnitude as the change due to the urban fluxes (+5%) in current climate conditions. Different climate change scenarios do not change the impact of the urban fluxes much except for the climate scenario that involves a strong increase in rainfall extremes in summer. This scenario leads to a strong increase of the impact of the urban fluxes on the river system.

  11. International uranium market

    Neff, T.L.; Jacoby, H.D.

    1980-12-01

    Discussed in this report are 1) how one might think about uranium demand, resources and supply, 2) how producers and consumers see the market and are likely to behave, including specifics about export and import commitments, and 3) how these actors are brought together in the international market. The general conclusion is that much of current anxiety about future uranium supply results primarily from a brief but difficult period in the mid- to late-1970's; and that current conditions and trends are favorable (at least to consumers) that there is now little basis for concern. Inventories contractual positions and producer commitments--when compared with realistic (or even unrealistic) demand estimates--imply a buyer's market for at least the next decade. The result will be considerable increases in market flexibility and resilience to shock, and real prices that are low relative to those of the past few years. There is a need to reconsider assumptions about desired directions of technological development, for many current programs were planned in an era of pessimism about uranium supply and process. Similar questions must be raided about nonproliferation policies that depend on some level of control of fuel supplies by the industrial nations. With a soft and more diversified uranium market, leverage that may have existed in the past is rapidly being eroded. Finally, as world prices turn soft, there may be significant problems created for U.S. uranium producers, who have relatively high costs in relation to several large-scale foreign suppliers

    1983-10-01

    The theoretical FASTGRASS model for the prediction of the behavior of the gaseous and volatile fission products in nuclear fuels under normal and transient conditions has undergone substantial improvements. The major improvements have been in the atomistic and bubble diffusive flow models, in the models for the behavior of gas bubbles on grain surfaces, and in the models for the behavior of the volatile fission products iodine and cesium. The thoery has received extensive verification over a wide range of fuel operating conditions, and can be regarded as a state-of-the-art model based on our current level of understanding of fission product behavior. PARAGRASS is an extremely efficient, mechanistic computer code with the capability of modeling steady-state and transient fission-product behavior. The models in PARAGRASS are based on the more detailed ones in FASTGRASS. PARAGRASS updates for the FRAPCON (PNL), FRAP-T (INEL), and SCDAP (INEL) codes have recently been completed and implemented. Results from an extensive FASTGRASS verification are presented and discussed for steady-state and transient conditions. In addition, FASTGRASS predictions for fission product release rate constants are compared with those in NUREG-0772. 21 references, 13 figures

  14. Empowering wind power. On social and institutional conditions affecting the performance of entrepreneurs in the wind power supply market in the Netherlands

    Agterbosch, S.

    2006-01-01

    This dissertation focuses on wind energy for electricity generation, analysing the evolution of the wind power supply market in the Netherlands. We analysed different kind of wind power entrepreneurs (energy distributors, small private investors, wind cooperatives and new independent wind power producers), their capacity to implement wind energy and the social and institutional conditions that affected their investments over the period 1989-2004. Central in the analyses are the institutional regulatory dimension and the social context as explanatory variables for the emergence and performance of these wind power entrepreneurs. Special attention is given to the liberalisation of the electricity market. The primary social actors for the implementation of wind energy projects in a liberalised market are entrepreneurs willing to invest. Understanding conditions that trigger entrepreneurs to invest in these projects, and understanding conditions that determine the chance of success for entrepreneurs to implement and exploit their projects, is vital for setting up effective policies to stimulate wind electricity generation. The analytical perspective that we used to study investment behaviour of wind power entrepreneurs and their capacity to implement wind energy can be referred to as the 'new institutional perspective'. Based on this new institutional perspective the concept of implementation capacity has been developed. Implementation capacity indicates the feasibility for wind power entrepreneurs to adopt wind turbines, and enables to explain, comparatively, changing possibilities in time for different types of entrepreneurs. The development of the wind power supply market is divided into three successive market periods: Monopoly powers (1989-1995), Interbellum (1996-1997) and Free market (1998-2002). We conducted case studies on the implementation capacity of the four entrepreneurial groups in each of the three market periods. The case studies led to conclusions

    For infrastructure design, operations, and maintenance requirements in the North the ability to accurately and efficiently detect the presence (or absence) of ground ice in permafrost terrains is a serious challenge. Ground ice features including ice wedges, thermokarst cave-ice, and segregation ice are present in a variety of spatial scales and patterns. Currently, most engineering applications use borehole logging and sampling to extrapolate conditions at the point scale. However, there is high risk of over or under estimating the presence of frozen or unfrozen features when relying on borehole information alone. In addition, boreholes are costly, especially for planning linear structures like roads or runways. Predicted climate warming will provide further challenges for infrastructure development and transportation operations where permafrost degradation occurs. Accurately identifying the subsurface character in permafrost terrains will allow engineers and planners to cost effectively create novel infrastructure designs to withstand the changing environment. There is thus a great need for a low cost rapidly deployable, spatially extensive means of 'measuring' subsurface conditions. Geophysical measurements, both terrestrial and airborne, have strong potential to revolutionize our way of mapping subsurface conditions. Many studies in continuous and discontinuous permafrost have used geophysical measurements to identify discrete features and repeatable patterns in the subsurface. The most common measurements include galvanic and capacitive coupled resistivity, ground penetrating radar, and multi frequency electromagnetic induction techniques. Each of these measurements has strengths, weaknesses, and limitations. By combining horizontal geophysical measurements, downhole geophysics, multispectral remote sensing images, LiDAR measurements, and soil and vegetation mapping we can start to assemble a holistic view of how surface conditions and standoff measurements

    Full Text Available Purpose. To assess the developmental stability and cytogenetic homeostasis of fish populations in the Sluch River in the watercourse areas subjected to anthropogenic stress of different intensities. Methodology. Studies of fish populations in the Sluch River were carried out within Berezne district of Rivne region. The condition of individual fish in the populations were evaluated integrally using morphological (evaluation of the stability of development based on the level of fluctuating asymmetry (FA and cytogenetic (micronucleus (MN test of peripheral blood erythrocytes of fish methods. The methods used allowed identifying the destabilization level of organism development, even in the cases when there is no direct disturbance of population homeostasis. Findings. The found FA levels reflect minor (initial deviations from the normal developmental processes of fish populations in in the studied watercourse areas. Especially significantly this is reflected in a high proportion of individuals with FA in the samples of roach (Rutilus rutilus, bleak (Alburnus alburnus, bream (Abramis brama and perch (Perca fluviatilis. An excess in the frequency of MN erythrocyte cells in roach and pike (Esox lucius blood relatively the level of spontaneous mutagenesis was observed in the cross section №2, which is exposed to sewage waters. The observed manifestation of degenerative processes in fish organisms at this stage can be evaluated as an increased reactivity of sensitive species to the presence of mutagenic agents in the composition of river pollution. The functioning of spawning populations gives reason to believe that the current level of human impact is not critical for the hydroecosystem. Originality. For the first time we obtained data on the stability of development and cytogenetic homeostasis of fish populations in the hydroecosystem of Rivne region in current conditions of anthropogenic stress.
