  1. The North American electricity markets

    International Nuclear Information System (INIS)

    Harvie, I.

    1999-01-01

    The wide ranging changes that will drive the evolution of the North American electricity industry in the future are discussed. Deregulation and the advent of competition in both the United States and Canada are the principal forces that will change the shape of the electricity market, bringing new players and new forms of doing business into the marketplace. A review of the current state of the business shows that especially in the United States where deregulation began earlier than in Canada, independent generators already constitute a multi-billion dollar industry. Non-utility generation capacity is about seven per cent of total U.S. capacity and accounts for about 10 per cent of total U. S. electricity supply, including imports. Examples from other industries clearly show that restructuring and the breakup of vertically integrated industries could be accomplished much faster than anticipated, that a decrease in prices followed rapidly as products became more like commodities, and that decreasing prices fostered product differentiation and competition. Major legislation affecting the electric power industry in the U.S. and Canada (U.S. National Energy Policy Act 1992, Alberta Electric Utilities Act 1995, Ontario Energy Competition Act 1998) decreeing open access transmission, unbundling of generation, transmission and ancillary services, and promoting competition, and the impacts of these legislative actions are also reviewed. The most visible impact is the explosion that can be seen in power marketing and energy trading on a scale unimaginable only a few short years ago, where the total volume of trade may be worth multiples of the value of the underlying commodity. At the same time, there is concern about the reliability of the system, and thus making it imperative to find new ways to manage reliability. Various suggestions are made as to how increased reliability of supply could be achieved by better management, new standards and better enforcement of

    1982-01-01

    The author took part in the Annual Congress of the Edison Electric Institute from the 3rd to the 5th of May in Los Angeles and subsequently visited the Electric Power Research Institute in Palo Alto. This continuation of the Report outlines how the development of energy prices, special financial and economic factors, multiferous state legislative controls and also psychological influences have precipitated the establishment of new perspectives in the electricity economy in the USA. The subjects nuclear energy and environmental protection are especially highlighted. The author describes the resulting consequences. In the USA one remains convinced that the difficulties can be optimally overcome by private concerns. On the private company sector of the American supply concerns the associations EEI and EPRI, both featured in the report, play a significant role. (orig.) [de

    2006-03-01

    Electricity supply and infrastructure solutions for the United States and Canada were discussed along with the availability of fuel supply and the diversity of fuel sources. This document focuses on investment in transmission infrastructure in order to assure sustainable generation sources for both countries while addressing constraints along the border, which will allow for enhanced cross-border trade. The Canadian Electricity Association has proposed 3 areas of bi-national cooperation to promote effective investment in electricity infrastructure and supply in the North American market: (1) cooperation in enhancing electricity supply, (2) cooperation in enhancing transmission infrastructure, and (3) cooperation in addressing air quality issues and climate change. The report discussed electricity generation by fuel source in Canada and the United States; status of restructuring in Canada; as well as the economic and environmental benefits of an integrated market. It also discussed regulatory and policy matters affecting the investment environment. Last, it discussed the need for opportunities for investment in the North American market, distribution and demand side measures, and cooperation in enhancing transmission infrastructure. It was concluded that growing electricity demand in both the United States and Canada requires investment in electricity infrastructure and supply in the future. Resolving electricity infrastructure and supply needs must be an international concern, requiring the full engagement and cooperation of both countries. 1 tab, 2 figs

    2003-01-01

    At its 108th session on the 20 June 1997, the Council approved the Report of the Finance Committee Working Group on the Review of CERN Purchasing Policy and Procedures. Among other topics, the report recommended the inclusion of utility supplies in the calculation of the return statistics as soon as the relevant markets were deregulated, without reaching a consensus on the exact method of calculation. At its 296th meeting on the 18 June 2003, the Finance Committee approved a proposal to award a contract for the supply of electrical energy (CERN/FC/4693). The purpose of the proposal in this document is to clarify the way electrical energy will be included in future calculations of the return statistics. The Finance Committee is invited: 1. to agree that the full cost to CERN of electrical energy (excluding the cost of transport) be included in the Industrial Service return statistics; 2. to recommend that the Council approves the corresponding amendment to the Financial Rules set out in section 2 of this docum...

  10. Electricity consumption and economic growth in seven South American countries

    International Nuclear Information System (INIS)

    Yoo, Seung-Hoon; Kwak, So-Yoon

    2010-01-01

    This paper attempts to investigate the causal relationship between electricity consumption and economic growth among seven South American countries, namely Argentina, Brazil, Chile, Columbia, Ecuador, Peru, and Venezuela using widely accepted time-series techniques for the period 1975-2006. The results indicate that the causal nexus between electricity consumption and economic growth varies across countries. There is a unidirectional, short-run causality from electricity consumption to real GDP for Argentina, Brazil, Chile, Columbia, and Ecuador. This means that an increase in electricity consumption directly affects economic growth in those countries. In Venezuela, there is a bidirectional causality between electricity consumption and economic growth. This implies that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in that country. However, no causal relationships exist in Peru. The documented evidence from seven South American countries can provide useful information for each government with regard to energy and growth policy.

  11. Deregulating electricity in the American states

    Science.gov (United States)

    Terbush, Thomas Lee

    This dissertation develops nine stylized facts that summarize the major consequences of deregulation and tests these against recent experience in the electric utility industry. The experience of the electric utility industry matches the predictions of the stylized facts, except in one instance: although real electricity prices fell between 1982 and 1999, real prices fell less in states that deregulated. This dissertation presents three possible explanations for this discrepancy. First, through dynamic efficiency, consumers may benefit in the long run through lower rates and better service in the electricity market, or deregulation may be a public good that benefits electricity consumers through economy-wide improvements in efficiency. Second, higher prices may be a long-run outcome as predicted by the theory of the second best. Or third, both regulators and utilities may use deregulation to generate new rents. Because the original rents from regulation had dissipated, new rents could be generated under deregulation by making consumers pay off the utilities and then creating more new rents through re-regulation of the industry. Close examination tends to support the first and third explanations, although the second-best explanation cannot yet be ruled out completely. Higher prices appear to be a transitional phenomenon, resulting from a short-term payoff from consumers to incumbent utilities that was required to move deregulation forward. This payoff occurs as residential and commercial consumers bear relatively higher rates over three to five years to compensate utilities for stranded costs, investments thought to be unrecoverable under full competition. All states are benefiting from deregulation, but states that are deregulating are benefiting less while stranded costs are being recovered. This dissertation also examines California electricity deregulation and finds that the experience in California conforms with to the stylized facts, and that certain structural

    The US electric utility industry is undergoing a period of fundamental change that has significant implications for Native American tribes. Although many details remain to be determined, the future electric power industry will be very different from that of the present. It is anticipated that the new competitive electric industry will be more efficient, which some believe will benefit all participants by lowering electricity costs. Recent developments in the industry, however, indicate that the restructuring process will likely benefit some parties at the expense of others. Given the historical experience and current situation of Native American tribes in the US, there is good reason to pay attention to electric industry changes to ensure that the situation of tribes is improved and not worsened as a result of electric restructuring. This paper provides a review of electricity restructuring in the US and identifies ways in which tribes may be affected and how tribes may seek to protect and serve their interests. Chapter 2 describes the current status of energy production and service on reservations. Chapter 3 provides an overview of the evolution of the electric industry to its present form and introduces the regulatory and structural changes presently taking place. Chapter 4 provides a more detailed discussion of changes in the US electric industry with a specific focus on the implications of these changes for tribes. Chapter 5 presents a summary of the conclusions reached in this paper.

  13. Transport modelling including radial electric field and plasma rotation

    1994-01-01

    Using a simple turbulent transport model with a constant diffusion coefficient and a fixed temperature profile, the density profile in a steady state and the transient behaviour during the co and counter neutral beam injection are studied. More consistent analysis has been initiated with a turbulent transport model based on the current diffusive high-n ballooning mode. The enhancement of the radial electric field due to ion orbit losses and the reduction of the transport due to the poloidal rotation shear are demonstrated. The preliminary calculation indicates a sensitive temperature dependence of the density profile. (author)

  14. Latin American electric power developments and hydrocarbon demands

    International Nuclear Information System (INIS)

    Sierra, G.S.

    1994-01-01

    Energy sectors in Latin American countries are undergoing a series of far-reaching changes in institutional arrangements and roles. These changes will have a decisive influence on energy sector evolution in coming decades. The results of two decades of mismanagement in the region's energy sector are outlined, showing stagnation in the electric power and petroleum industries caused by such factors as bureaucratic management, preferential treatment given to public enterprises, the adoption of objectives other than economic profitability, insufficient self-generation of resources due to tariffs not reflecting economic costs, and heavy debt burdens. If forecasts of future energy demand in Latin America are correct, the region's hydrocarbon sector will have to invest ca US$20 billion/y and the electric power sector nearly the same amount. This is considered beyond the capacity of the region's industries. Private sector participation is expected to raise the efficiency level of the hydrocarbon and power industries through such initiatives as privatization (complete or partial), joint government-private ventures, subcontracting, direct investment, and opening of monopolies such as power distribution to third-party competition. The state role in this process will be to create a suitable environment for private enterprise including clear and stable rules and regulatory frameworks. Financing options are discussed along with ways to reduce investment requirements. It is especially possible to reduce such requirements in the power sector through such means as retrofitting of plants with more modern equipment, reducing power losses, improved metering and billing, energy substitution, demand-side management, and energy conservation programs

  18. Canadian electricity and the economy : developing a North American energy perspective : a proposal for action on electricity

    International Nuclear Information System (INIS)

    Egan, T.

    2002-03-01

    This report provided a Canadian industry perspective on strategies to improve the way electricity markets operate in North America, particularly following the events of September 11, 2001 which highlighted how closely the integrated infrastructure between Canada and the United States really is. Other major and recent events that have influenced the process of fundamental change across much of the North American electricity industry include the electricity crisis in California, the downturn in the North American economy, and the collapse of Enron. These events have forced governments to work collaboratively on integrating policy initiatives related to electricity. This report also discussed the impact that the U.S. withdrawal from the Kyoto Protocol would have on Canada. Canada is not yet on a path to meet the greenhouse gas emission reduction target of 6 per cent below 1990 levels by 2008-2012. Should Canada decide to implement Kyoto, the fact that the U.S. plan is much less aggressive than Kyoto, would place Canada at a cost disadvantage relative to its major trading partner. The Canadian Electricity Association (CEA) believes that this problem can be solved using a continental approach to climate change with realistic targets to reduce greenhouse gases over a long-term period. The energy strategy delivered by the Bush administration focuses on security of supply. Within Canada, there is no crisis in supply, and to keep it that way, due attention must be given to future demand through investment in new generation and transmission. The CEA believes that an effective partnership between Canada and the United States would ensure security and economic advantages for both countries. This report summarized the following: (1) electricity generation by fuel type in Canada and the United States in 2000, (2) electricity exports from Canada and imports from United States from 1992 to 2001, (3) volume of net exports and imports in 2001, and (4) the status of restructuring in

  2. Environmental challenges and opportunities of the evolving North American electricity market

    International Nuclear Information System (INIS)

    2002-06-01

    On April 22, 2001 a joint statement was issued by the Prime Minister of Canada, the Mexican President and the United States President concerning the opportunities for North American cooperation on environment and energy. Efforts are being made by representatives from the three countries to find innovative approaches for expanding the production, distribution and trade in energy, including electricity. Competition in the electricity sector has either been implemented or is under consideration in several jurisdictions within the three countries. The designs of electricity markets that would deliver affordable and reliable electricity in the region are being explored to protect the health and environment of citizens and their neighbours. Fuel choice, technology, pollution control strategies and subsidies are factors that are directly influenced by policy measures. Achieving the twin goals of clean and abundant electricity is dependent on the degree of coordinated interaction between the three countries. To prepare this report, members of the Commission for Environmental Cooperation (CEC) of North America Electricity and Environment Advisory Board, governments and the general public reviewed and exchanged on key policy issues related to market integration in the electricity sector. Convergence in competitiveness and trade policy is underway in those countries. Secure health and environmental safety nets are called for in the face of uncertainties concerning several characteristics of the electricity sector, such as planned and future generation capacity and location, demand, fuel type and technology. Measures designed to reduce adverse environmental effects might result in efficient and effective regional initiatives generating resources to be used in protection and conservation of the environment. Access to information, environmental impact assessment and integrated resource planning could all be enhanced through cooperation by the three countries on the policy front

  3. Assessing CO2 Mitigation Options Utilizing Detailed Electricity Characteristics and Including Renewable Generation

    Science.gov (United States)

    Bensaida, K.; Alie, Colin; Elkamel, A.; Almansoori, A.

    2017-08-01

    This paper presents a novel techno-economic optimization model for assessing the effectiveness of CO2 mitigation options for the electricity generation sub-sector that includes renewable energy generation. The optimization problem was formulated as a MINLP model using the GAMS modeling system. The model seeks the minimization of the power generation costs under CO2 emission constraints by dispatching power from low CO2 emission-intensity units. The model considers the detailed operation of the electricity system to effectively assess the performance of GHG mitigation strategies and integrates load balancing, carbon capture and carbon taxes as methods for reducing CO2 emissions. Two case studies are discussed to analyze the benefits and challenges of the CO2 reduction methods in the electricity system. The proposed mitigations options would not only benefit the environment, but they will as well improve the marginal cost of producing energy which represents an advantage for stakeholders.

  4. Environmental challenges and opportunities of the evolving North American electricity market : Design and legal considerations for North American emissions trading

    International Nuclear Information System (INIS)

    Russell, D.

    2002-06-01

    When considering a multi-pollutant emissions trading system covering Mexico, the United States and Canada, several issues must be looked at. Such a system would result from the changing environment in the electricity sector. An understanding of the architectural elements involved in the design of an emissions trading regime was the stated goal for the preparation of this working paper. In the event of the implementation of a North American emissions trading system, some potential interface issues resulting from the North American Free Trade Agreement (NAFTA) were identified. An overview of the emissions trading systems currently in place in North America and their results was included in a background paper, as well as a description of architectural elements comprised in the design of an emissions trading system, the implications of cross-border harmonization taking into account environmental integrity and economic efficiency, and potential trade issues. This paper was circulated among a broad section of policy experts in environmental matters, and was then discussed at an informal workshop in December 2001, attended by 25 cross-sectoral experts. The author also identified several areas where further work is required. refs., 2 tabs

    In this report we discuss static and time dependent electric fields in detector geometries with an arbitrary number of parallel layers of a given permittivity and weak conductivity. We derive the Green's functions i.e. the field of a point charge, as well as the weighting fields for readout pads and readout strips in these geometries. The effect of 'bulk' resistivity on electric fields and signals is investigated. The spreading of charge on thin resistive layers is also discussed in detail, and the conditions for allowing the effect to be described by the diffusion equation is discussed. We apply the results to derive fields and induced signals in Resistive Plate Chambers, Micromega detectors including resistive layers for charge spreading and discharge protection as well as detectors using resistive charge division readout like the MicroCAT detector. We also discuss in detail how resistive layers affect signal shapes and increase crosstalk between readout electrodes.

  7. Comparison of electricity prices in major North American cities : rates effective May 1, 2001

    International Nuclear Information System (INIS)

    2002-01-01

    This report presents the major findings of a comparative evaluation of electricity prices in major North American cities, by customer category, based on rates in effect on May 1, 2001. Besides Hydro-Quebec, the comparison includes 21 utilities, of which 11 serve the major cities across Canada and 10 utilities located in 10 American states. Hydro-Quebec is one of the largest electric utilities in North America with one of the most extensive systems. Of the 190 billion kilowatt-hours delivered annually, 37 billion are exported to neighbouring provinces in Canada and to the United States. 93 per cent of the generating facilities are hydroelectric. The report covers consumption levels, taxes, optional programs, location, time-of-use rates, exchange rates, and other factors that affect electricity prices such as fuel adjustment clauses for utilities that produce electricity in thermal power plants. It was noted that Hydro-Quebec has frozen its rates until April 2002, keeping them at the same level as those set on May 1, 1998. The report showed that Hydro-Quebec has maintained a competitive position at a level similar to or better than previous years. Three of the 11 Canadian utilities implemented rate increases between May 1, 2000 and May 1, 2001, and 2 utilities reduced their rates. Two utilities modified their rate structure following deregulation. During the same time period, 3 of the 10 utilities in the United States increased their rates, and one reduced them. The rates in the United States varied regardless of increases or freezes because many utilities had incorporated adjustment clauses. Quebec residential consumers enjoy the second lowest rates in North America. Only Winnipeg ranked higher. Hydro-Quebec has also remained competitive when it comes to small, medium and large power customers. It ranked fifth for small power customers, third for medium power customers, and third for large power customers. tabs., figs., appendices

  8. Robert Hare's Theory of Galvanism: A Study of Heat and Electricity in Early Nineteenth-Century American Chemistry.

    Fisher, Amy

    2018-04-09

    As a professor of chemistry at the University of Pennsylvania, Robert Hare actively shaped early American science. He participated in a large network of scholars, including Joseph Henry, François Arago, and Jacob Berzelius, and experimented with and wrote extensively about electricity and its associated chemical and thermal phenomena. In the early nineteenth century, prominent chemists such as Berzelius and Humphry Davy proclaimed that a revolution had occurred in chemistry through electrical research. Examining Robert Hare's contributions to this discourse, this paper analyzes how Hare's study of electricity and the caloric theory of heat led him to propose a new theory of galvanism. It also examines the reception of Hare's work in America and Great Britain, highlighting the contributions of early American chemists to the development of electrochemistry.

    Liquefied natural gas (LNG) will contribute more in the future than in the past to the overall energy supply in the world. The paper discusses the application of advanced exergy-based analyses to a recently developed LNG-based cogeneration system. These analyses include advanced exergetic, advanced exergoeconomic, and advanced exergoenvironmental analyses in which thermodynamic inefficiencies (exergy destruction), costs, and environmental impacts have been split into avoidable and unavoidable parts. With the aid of these analyses, the potentials for improving the thermodynamic efficiency and for reducing the overall cost and the overall environmental impact are revealed. The objectives of this paper are to demonstrate (a) the potential for generating electricity while regasifying LNG and (b) some of the capabilities associated with advanced exergy-based methods. The most important subsystems and components are identified, and suggestions for improving them are made. (orig.)

  14. The integrated North American electricity market : a bi-national model for securing a reliable supply of electricity

    The 50 million people who experienced the power blackout on August 14, 2003 in southern Ontario and the U.S. Midwest and Northeast understood how vital electricity is in our day-to-day lives, but they also saw the resiliency of the North American electricity system. More than 65 per cent of the power generation was restored to service within 12 hours and no damage was caused to the generation or transmission facilities. Although the interconnected North American electricity system is among the most reliable in the world, it is threatened by an aging infrastructure, lack of new generation and transmission to meet demand, and growing regulatory pressures. This report suggests that any measures that respond to the threat of ongoing reliability should be bi-national in scope due to the interconnected nature of the system. Currently, the market, regulatory and administrative systems are different in each country. The full engagement and cooperation of both Canada and the United States is important to ensure future cross-border trade and power reliability. The Canadian Electricity Association proposes the following 7 measures: (1) support an open debate on all the supply options available to meet growing power demands, (2) promote bi-national cooperation in the construction of new transmission capacity to ensure a reliable continental electricity system, (3) examine opportunities for bi-national cooperation for investment in advanced transmission technologies and transmission research and development, (4) promote new generation technology and demand-side measures to relieve existing transmission constraints and reduce the need for new transmission facilities, (5) endorse a self-governing international organization for developing and enforcing mandatory reliability standards for the electricity industry, (6) coordinate measures to promote critical infrastructure protection, and (7) harmonize U.S. and Canadian efforts to streamline or clarify regulation of electricity

    In this case-control study, the authors aimed to examine whether use of an electric bedding device increased breast cancer risk in African-American women. Cases were 304 African-American patients diagnosed with breast cancer during 1995-1998 who were aged 20-64 years and lived in one of three Tennessee counties. Controls were 305 African-American women without breast cancer who were selected through random digit dialing and frequency-matched to cases by age and county. Information on the use of an electric blanket or heated water bed and other risk factors was collected through telephone interviews. Breast cancer risk associated with use of an electric bedding device increased with the number of years of use, the number of seasons of use, and the length of time of use during sleep. When women who used an electric bedding device for more than 6 months per year (and therefore were more likely to have used a heated water bed, which generates lower magnetic fields) were excluded, the corresponding dose-response relations were more striking. Similar trends in dose response were shown in both premenopausal and postmenopausal women and for both estrogen receptor-positive and estrogen receptor-negative tumors. The use of electric bedding devices may increase breast cancer risk in African-American women aged 20-64 years. Such an association might not vary substantially by menopausal status or estrogen receptor status.

  16. North american natural gas supply forecast: the Hubbert method including the effects of institutions

    2009-01-01

    In this article, the U.S. and southern Canadian natural gas supply market is considered. An important model for oil and natural gas supply is the Hubbert curve. Not all regions of the world are producing oil or natural gas following a Hubbert curve, even when price and market conditions are accounted for. One reason is that institutions are affecting supply. We investigate the possible effects of oil and gas market institutions in North America on natural gas supply. A multi-cycle Hubbert curve with inflection points similar to the Soviet Union's oil production multi-cycle Hubbert curve is used to determine North American natural gas discovery rates and to analyze how market specific institutions caused the inflection points. In addition, we analyze the latest shale natural gas projections critically. While currently, unconventional resources of natural gas suggest that North American natural gas production will increase without bound, the model here suggests a peak in North American natural gas supplies could happen in 2013.

    Ricin is one of the most toxic and easily produced plant protein toxin extracted from the castor oil plant, and it has been classified as a chemical warfare agent. Here, nanosecond pulsed electric fields (nsPEFs) at 30 kV/cm (pulse durations: 10 ns, 100 ns, and 300 ns) were applied to inactivating ricin up to 4.2 μg/mL. To investigate the efficacy, cells and mice were tested against the ricin treated by the nsPEFs via direct intraperitoneal injection and inhalation exposure. Results showed that nsPEFs treatments can effectively reduce the toxicity of the ricin. Without the nsPEFs treatment, 100% of mice were killed upon the 4 μg ricin injection on the first day, however 40% of the mice survived the ricin treated by the nsPEFs. Compared to injection, inhalation exposure even with higher ricin dose required longer time to observe mice fatality. Pathological observations revealed damages to heart, lung, kidney, and stomach after the ricin exposure, more pronounced for lung and kidney including severe bleeding. Sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE) and circular dichroism (CD) analyses revealed that although the primary structure of ricin was not altered, its secondary structures (beta-sheet and beta-turn) underwent transition upon the nsPEFs treatment.

  1. Energy-Water Nexus Relevant to Baseload Electricity Source Including Mini/Micro Hydropower Generation

    Fujii, M.; Tanabe, S.; Yamada, M.

    2014-12-01

    Water, food and energy is three sacred treasures that are necessary for human beings. However, recent factors such as population growth and rapid increase in energy consumption have generated conflicting cases between water and energy. For example, there exist conflicts caused by enhanced energy use, such as between hydropower generation and riverine ecosystems and service water, between shale gas and ground water, between geothermal and hot spring water. This study aims to provide quantitative guidelines necessary for capacity building among various stakeholders to minimize water-energy conflicts in enhancing energy use. Among various kinds of renewable energy sources, we target baseload sources, especially focusing on renewable energy of which installation is required socially not only to reduce CO2 and other greenhouse gas emissions but to stimulate local economy. Such renewable energy sources include micro/mini hydropower and geothermal. Three municipalities in Japan, Beppu City, Obama City and Otsuchi Town are selected as primary sites of this study. Based on the calculated potential supply and demand of micro/mini hydropower generation in Beppu City, for example, we estimate the electricity of tens through hundreds of households is covered by installing new micro/mini hydropower generation plants along each river. However, the result is based on the existing infrastructures such as roads and electric lines. This means that more potentials are expected if the local society chooses options that enhance the infrastructures to increase micro/mini hydropower generation plants. In addition, further capacity building in the local society is necessary. In Japan, for example, regulations by the river law and irrigation right restrict new entry by actors to the river. Possible influences to riverine ecosystems in installing new micro/mini hydropower generation plants should also be well taken into account. Deregulation of the existing laws relevant to rivers and

    2010-01-01

    From the mid eighties on, most of Latin American Countries reformed their energy systems. The impact of these reforms over electricity markets was different in each case. However, in the majority of these cases there was a shift to private participation, instead of State, and a convergence of electricity systems to hydro and thermal technologies. This is the case of Argentina and Chile. In this context, the aim of this paper is to discuss the current situation of renewable energies in Chilean and Argentinean electric markets and the potential to increase their share in total energy supply. To this purpose, we firstly study electricity deregulation process and its current situation. Secondly, we analyze renewable energy share in these electricity systems comparatively to worldwide situation. Finally, we briefly present the policy instruments used in each country. (author)

  4. Photovoltaic cell electrical heating system for removing snow on panel including verification.

    Science.gov (United States)

    Weiss, Agnes; Weiss, Helmut

    2017-11-16

    Small photovoltaic plants in private ownership are typically rated at 5 kW (peak). The panels are mounted on roofs at a decline angle of 20° to 45°. In winter time, a dense layer of snow at a width of e.g., 10 cm keeps off solar radiation from the photovoltaic cells for weeks under continental climate conditions. Practically, no energy is produced over the time of snow coverage. Only until outside air temperature has risen high enough for a rather long-time interval to allow partial melting of snow; the snow layer rushes down in an avalanche. Following this proposal, snow removal can be arranged electrically at an extremely positive energy balance in a fast way. A photovoltaic cell is a large junction area diode inside with a threshold voltage of about 0.6 to 0.7 V (depending on temperature). This forward voltage drop created by an externally driven current through the modules can be efficiently used to provide well-distributed heat dissipation at the cell and further on at the glass surface of the whole panel. The adhesion of snow on glass is widely reduced through this heating in case a thin water film can be produced by this external short time heating. Laboratory experiments provided a temperature increase through rated panel current of more than 10 °C within about 10 min. This heating can initiate the avalanche for snow removal on intention as described before provided the clamping effect on snow at the edge of the panel frame is overcome by an additional heating foil. Basics of internal cell heat production, heating thermal effects in time course, thermographic measurements on temperature distribution, power circuit opportunities including battery storage elements and snow-removal under practical conditions are described.

  5. Canadian electricity and the economy : developing a North American energy perspective : a proposal for action on electricity

    International Nuclear Information System (INIS)

    2001-05-01

    This paper presented an overview of the Canadian electric power industry and provided a Canadian industry perspective on what could be done to improve the way in which electricity markets operate in a North American Energy Framework. The measures outlined by the Canadian Electricity Association are based on the solid policy framework already in place in Canada and the United States which have focused on making energy systems more market responsive and reducing environmental impacts. In the past decade, Canadian and U.S. energy markets have become more interdependent regarding oil and gas and electricity in particular. This paper argued the point that while this interdependence has benefited consumers and producers in both countries, it is important to take measures to ensure energy security. In particular, the paper focused on a domestic supply shortage in the U.S. and is aimed at decision-makers and policy advisors in Canada and the United States to strengthen the Canada-U.S electricity partnership

    1977-02-01

    It has been evident to some future-looking individuals for some time that both the availability of abundant cheap energy supplies and the exponential increasing use of unlimited amounts must change. However, official energy policy thinking in the U.S. either fails to believe that 'times have changed' or, if believing, is responding in a deleterious and counter-productive manner. This fantastically pervasive and interactive problem cannot be dealt with in the long run by any policy of 'normalizing', of trying to return to doing more with more. The more successful the U.S. is in maintaining or increasing its total energy consumption under conditions of declining net energy, or striving for simplistic first-law efficiencies without analyzing the second level or entropy effects or realizing that every energy exchange adds a minute but rapidly aggregating portion to the environmental pollution limit--doing more with more--the more rapidly inflation, unemployment, and general economic instability will increase. A small group of architectural professionals, the American Institute of Architects, has proposed an alternate energy strategy, essentially doing more with less which, if pursued, can provide more jobs, less inflation, less pollution, and the potential for better matching of energy task and source (entropy efficiency). This strategy exemplifies the characteristics of an appropriate technology response. It stresses capital and energy as well as labor productivity.

    2005-03-01

    The purpose of this paper is to support cooperation and discussion of the long-term sufficiency of the electricity trading system between Canada and the United States. It discusses the integrated electricity market including details on exports and imports of electricity, major transmission interconnections, the economic and environmental benefits of an integrated market and electricity generation statistics by fuel source. The paper also discusses several areas of cooperation and presents several recommendations including: greater dialogue on regional supply requirements; mandatory reliability standards; coordinated regulatory approaches to new cross-border transmission; the role of emerging generation and transmission technologies; opportunities to exchange experience and learning on demand-side measures; coordinated strategies to manage greenhouse gas and other air pollutants; and, critical infrastructure protection. The paper concludes that the integration between Canada and the United States will only increase as energy demand and trade continue to grow, making close cooperation between the two countries a necessity. 6 figs

    2003-03-01

    The stability of the North American electricity industry has always been recognized, in both Canada and the United States. However, this sector is facing uncertainty mainly due to lack of clarity concerning market rules, environmental challenges, and the very poor investment climate. The principal thesis that was developed for this paper used those three factors as context and justification. The thesis is as follows: the evolving North American market is more and more regionally integrated, and that continued and growing regional integration will lessen uncertainty. All problems cannot be solved simply through increased regional integration, but it represents a step in the right direction in that it leads to greater efficiency, increased reliability, more predictable regulation and policy, lower costs and greater environmental benefits. The result is increased investor confidence and reduced uncertainty in the marketplace. To assist in the strengthening of this integration, the Canadian Electricity Association made seven recommendations. They were: (1) increased focus on harmonizing market rules and increased participation in the Regional Transmission Organizations, (2) development of North American strategy for the management of greenhouse gas emissions resulting from electricity generation, (3) identification of oportunites to further harmonize management of other air emissions, (4) creation of consistent methodology for the measurement of environmental performance, (5) enhancement of cross-border and interprovincial transmission transfer capability, (6) coordination of critical infrastructure protection, and (7) support of self-governing international organization for the development and enforcement of mandatory reliability standards for the evolving electricity industry. 5 figs

    Ultraviolet (UV)-visible spectra and surface resistance measurement were used to investigate optical transmittance and conductive properties of carbon nanotube (CNT) and indium tin oxide (ITO) coated polyethylene terephthalate (PET) substrates. Conductive CNT and ITO coatings were successfully fabricated on PET by a spray-coating method. Thin coatings of both materials exhibited good conductivity and transparency. Changes in electrical and optical properties of the coatings were studied as a function of the coating suspension concentration. Interfacial durability of the coatings on PET substrates was also investigated under fatigue and bending loads. CNT coated substrates, with high aspect ratios, exhibited no detectable change in surface resistance up to 2000 cyclic loadings, whereas the ITO coated substrates exhibited a substantial increase in surface resistance at 1000 loading cycles. This change in resistance is attributed to a reduction in the number and effectiveness of the electrical contact points due to the inherent brittle nature of ITO.

  14. Development and Implementation of a Battery-Electric Light-Duty Class 2a Truck including Hybrid Energy Storage

    Science.gov (United States)

    Kollmeyer, Phillip J.

    This dissertation addresses two major related research topics: 1) the design, fabrication, modeling, and experimental testing of a battery-electric light-duty Class 2a truck; and 2) the design and evaluation of a hybrid energy storage system (HESS) for this and other vehicles. The work begins with the determination of the truck's peak power and wheel torque requirements (135kW/4900Nm). An electric traction system is then designed that consists of an interior permanent magnet synchronous machine, two-speed gearbox, three-phase motor drive, and LiFePO4 battery pack. The battery pack capacity is selected to achieve a driving range similar to the 2011 Nissan Leaf electric vehicle (73 miles). Next, the demonstrator electric traction system is built and installed in the vehicle, a Ford F150 pickup truck, and an extensive set of sensors and data acquisition equipment is installed. Detailed loss models of the battery pack, electric traction machine, and motor drive are developed and experimentally verified using the driving data. Many aspects of the truck's performance are investigated, including efficiency differences between the two-gear configuration and the optimal gear selection. The remainder focuses on the application of battery/ultracapacitor hybrid energy storage systems (HESS) to electric vehicles. First, the electric truck is modeled with the addition of an ultracapacitor pack and a dc/dc converter. Rule-based and optimal battery/ultracapacitor power-split control algorithms are then developed, and the performance improvements achieved for both algorithms are evaluated for operation at 25°C. The HESS modeling is then extended to low temperatures, where battery resistance increases substantially. To verify the accuracy of the model-predicted results, a scaled hybrid energy storage system is built and the system is tested for several drive cycles and for two temperatures. The HESS performance is then modeled for three variants of the vehicle design, including the

  18. Environmental challenges and opportunities of the evolving North American electricity market : Estimating future air pollution from new electric power generation

    International Nuclear Information System (INIS)

    Miller, P.; Patterson, Z.; Vaughan, S.

    2002-06-01

    A significant source of air pollutants and greenhouse gases in North America is a direct result of the generation of electricity from the combustion of fossil fuels. An attempt at estimating the future emissions of four key pollutants from the electricity generation sector in North America was made by the authors in this paper. They based their estimates on projections of future electricity generation capacity changes. They looked at new power plant projects in North America, as well as the expected changes in emissions as a result of these projects compared to the historical data originating from power plant emissions in the recent past. Both the local context and the national level were examined. Nitrogen oxides, sulfur dioxide, mercury, and carbon dioxide, all arising from the combustion of fossil fuels, were considered in this paper. Ground level ozone, or smog results from nitrogen oxides. Acidic deposition, also called acid rain, is caused in part by both nitrogen oxides and sulfur dioxide, as is fine particles in the atmosphere linked to lung damage and premature death. Fish consumption advisories were issued due to the levels of toxic mercury deposited in lakes and streams. Global climate change is caused in part to the greenhouse gas carbon dioxide. Air quality and climate change will both be impacted by the future evolution of the electricity generation sector in an integrated North American energy market. The authors attempted to provide a baseline of air emissions from that sector in North America for a common reference year, enabling the tracking of changes in emissions patterns in the future. A reference case inventory for the four pollutants was estimated, followed by the development of two boundary cases estimating future emissions in 2007. refs., 22 tabs

    Solid wastes are important environmental problem all over the World. Consumption of the plastic solid waste covers big portion within the total solid waste. Although a numerous plastic material is subjected to the recycling process, it is not easy to be destroyed by nature. One of the recommended way to prevent is to utilize as an aggregate in cement-based material. There are many researches on use of recycling rubber in concrete. However, studies on recycling of waste electrical cable rubber (WECR) in concrete is insufficient although there are many research on waste tyre rubbers in concrete. In this study, fine aggregate was replaced with WECR which were 5%, 10%, and 15 % of the total aggregate volume in the concrete and researched workability, unit weight, water absorption, compressive strength, flexural strength, ultrasonic pulse velocity, modulus of elasticity, and abrasion resistance of concrete. As a result of experimental studies, increase of WECR amount in concrete increases workability due to lack of adherence between cement paste and WECR, and hydrophobic structure of WECR while it influences negatively mechanical properties of concrete. It is possible to use WECR in concrete taking into account the reduction in mechanical properties.

  20. Comparable ages for the independent origins of electrogenesis in African and South American weakly electric fishes.

    Directory of Open Access Journals (Sweden)

    Sébastien Lavoué

    Full Text Available One of the most remarkable examples of convergent evolution among vertebrates is illustrated by the independent origins of an active electric sense in South American and African weakly electric fishes, the Gymnotiformes and Mormyroidea, respectively. These groups independently evolved similar complex systems for object localization and communication via the generation and reception of weak electric fields. While good estimates of divergence times are critical to understanding the temporal context for the evolution and diversification of these two groups, their respective ages have been difficult to estimate due to the absence of an informative fossil record, use of strict molecular clock models in previous studies, and/or incomplete taxonomic sampling. Here, we examine the timing of the origins of the Gymnotiformes and the Mormyroidea using complete mitogenome sequences and a parametric bayesian method for divergence time reconstruction. Under two different fossil-based calibration methods, we estimated similar ages for the independent origins of the Mormyroidea and Gymnotiformes. Our absolute estimates for the origins of these groups either slightly postdate, or just predate, the final separation of Africa and South America by continental drift. The most recent common ancestor of the Mormyroidea and Gymnotiformes was found to be a non-electrogenic basal teleost living more than 85 millions years earlier. For both electric fish lineages, we also estimated similar intervals (16-19 or 22-26 million years, depending on calibration method between the appearance of electroreception and the origin of myogenic electric organs, providing rough upper estimates for the time periods during which these complex electric organs evolved de novo from skeletal muscle precursors. The fact that the Gymnotiformes and Mormyroidea are of similar age enhances the comparative value of the weakly electric fish system for investigating pathways to evolutionary novelty

    Using a production function approach based on Cobb–Douglas, this analysis relates R&D efforts of 32 electric utilities on both sides of the Atlantic to their performance in terms of labour productivity. We find that higher R&D levels generally have a positive impact on revenues. However, only in the sub-sample of 16 electricity suppliers in Europe this effect is significant. Knowledge spill-over effects can be estimated for the US American sub-sample, since US utilities have bundled their R&D efforts in a centralized research institution and have to report that data. Our analysis reveals, though, that collaborative research efforts do not lead to positive spill-overs at the assumption of a time delay of one year. - Highlights: • R&D expenditures and their impact on performance of 32 electric utilities are analyzed. • Extended Cobb–Douglas production function approach. • Positive and significant effect of R&D expenditures on revenues. • Effect is less pronounced in the USA than in Europe. • External knowledge spillovers of 16 US American utilities turn out to be negative.

This is an indication of the wealth accumulated within the Malaysian economy. The infrastructure developments identified are designed to take the country towards Vision 2020. These infrastructure developments will continue to make the country highly attractive to foreign investors, who were the catalyst for Malaysia`s explosive growth over the last few years. Malaysian Corporations have also grown rapidly and are becoming international investors and traders in their own right, including in the United Kingdom. As they expand, seeking new markets, they are looking also for partners with whom they can share technology and jointly develop projects. Such companies are often ideal partners for UK companies wishing to enter the Malaysian and Asian market. Malaysia offers opportunities to companies prepared to make the small effort to know and understand the country and its people. This report will assist companies to develop a useful understanding of the market. (author)

  4. Managing realities of the new market uncertainty : standards development in the North American electricity industry

    International Nuclear Information System (INIS)

    Green, B.

    2003-01-01

    Standards for the electricity industry are developed to ensure quality and serve as a basis to which utilities should conform. Standards specify agreed upon properties for a manufactured product. They should be used for equipment specifications as well as operational procedures. Standardization is performed by regulators, transmission owners/operators, and organizations such as the National Electric Reliability Council (NERC), the Northeast Power Coordinating Council (NPCC), the North American Energy Standards Board (NAESB), and the Committee of Chief Risk Officers (CCRO). Before markets were opened to competition, operational standards were dictated by transmission owners and reliability issues were dealt with by NERC and NPCC. This presentation explained the process of standardization in the electric power industry in Canada, the derivation of standards, moving beyond NERC, and the transmission owners. Issues for Ontario Power Generation were highlighted. In contrast to the situation in the United States, there is no federal government backstop for developing Standards in Canada. There is no federal initiative toward open access. Canadian utilities participated in NERC, but compliance was voluntary. It is still questionable if Canadian utilities will implement NERC and NAESB Standards if they are codified

    Purpose To update the ASCO/Oncology Nursing Society (ONS) Chemotherapy Administration Safety Standards and to highlight standards for pediatric oncology. Methods The ASCO/ONS Chemotherapy Administration Safety Standards were first published in 2009 and updated in 2011 to include inpatient settings. A subsequent 2013 revision expanded the standards to include the safe administration and management of oral chemotherapy. A joint ASCO/ONS workshop with stakeholder participation, including that of the Association of Pediatric Hematology Oncology Nurses and American Society of Pediatric Hematology/Oncology, was held on May 12, 2015, to review the 2013 standards. An extensive literature search was subsequently conducted, and public comments on the revised draft standards were solicited. Results The updated 2016 standards presented here include clarification and expansion of existing standards to include pediatric oncology and to introduce new standards: most notably, two-person verification of chemotherapy preparation processes, administration of vinca alkaloids via minibags in facilities in which intrathecal medications are administered, and labeling of medications dispensed from the health care setting to be taken by the patient at home. The standards were reordered and renumbered to align with the sequential processes of chemotherapy prescription, preparation, and administration. Several standards were separated into their respective components for clarity and to facilitate measurement of adherence to a standard. Conclusion As oncology practice has changed, so have chemotherapy administration safety standards. Advances in technology, cancer treatment, and education and training have prompted the need for periodic review and revision of the standards.

    Full Text Available Objective: to describe cultural beliefs and medication-taking-behavior about pregnancy in African-American and Latina women. Design: qualitative study using phenomenological methodology; face-to-face, semi structured interviews and focus group. Thematic analysis was done to obtain themes consistent with the research objective. Setting: Maricopa County, Arizona, Department of Public-health Programs, November 2008 through April 2009.Participants: women seeking public-health services in the greater Phoenix, Arizona.Results: fifteen adult women representing two ethnic groups (seven African-Americans and eight Latinas participated. Themes derived from the interview data included: “The Dilemma: To Become or Not to Become Pregnant;” “The Ideal Stress-free World: Support System;” “Changing Worlds: Wanting Dependency;” and “The Health care System: Disconnection from Pregnancy to Postpartum.”Conclusions: based on the cultural themes: 1. pregnancies were not planned; 2. healthy life-style changes were not likely to occur during pregnancy; 3. basic facts about the biology of sexual intercourse and pregnancy were not understood, and there was no usage of any preconceptional or prenatal medications; and 4. professional health care was not desired or considered necessary (except during delivery. These cultural beliefs can contribute to negative birth outcomes, and need to be considered by pharmacists and other health-care providers. The information gained from this study can guide the implementation of educational programs developed by pharmacists that are more sensitive to the cultural beliefs and points of view of these particular women. Such programs would thus be more likely to be favorably received and utilized.

  9. Lithospheric layering in the North American craton revealed by including Short Period Constraints in Full Waveform Tomography

    2017-12-01

    Recent receiver function studies of the North American craton suggest the presence of significant layering within the cratonic lithosphere, with significant lateral variations in the depth of the velocity discontinuities. These structural boundaries have been confirmed recently using a transdimensional Markov Chain Monte Carlo approach (TMCMC), inverting surface wave dispersion data and converted phases simultaneously (Calò et al., 2016; Roy and Romanowicz 2017). The lateral resolution of upper mantle structure can be improved with a high density of broadband seismic stations, or with a sparse network using full waveform inversion based on numerical wavefield computation methods such as the Spectral Element Method (SEM). However, inverting for discontinuities with strong topography such as MLDS's or LAB, presents challenges in an inversion framework, both computationally, due to the short periods required, and from the point of view of stability of the inversion. To overcome these limitations, and to improve resolution of layering in the upper mantle, we are developing a methodology that combines full waveform inversion tomography and information provided by short period seismic observables. We have extended the 30 1D radially anisotropic shear velocity profiles of Calò et al. 2016 to several other stations, for which we used a recent shear velocity model (Clouzet et al., 2017) as constraint in the modeling. These 1D profiles, including both isotropic and anisotropic discontinuities in the upper mantle (above 300 km depth) are then used to build a 3D starting model for the full waveform tomographic inversion. This model is built after 1) homogenization of the layered 1D models and 2) interpolation between the 1D smooth profiles and the model of Clouzet et al. 2017, resulting in a smooth 3D starting model. Waveforms used in the inversion are filtered at periods longer than 30s. We use the SEM code "RegSEM" for forward computations and a quasi-Newton inversion

    2002-06-01

    The Secretariat of the Commission for Environmental Cooperation (CEC) was responsible for the preparation of this working paper that identifies key issues related to the evolving electricity sector and the environment. It was decided to approach the topics from an anecdotal or case-by-case basis, as the issues are very complex and the scope wide. There are ongoing discussions concerning principles, design, rules, institutional structure and consequences pertaining to the introduction of free markets in the electricity sector. Efficiency gains will be realised over time, as was argued in the paper by advocates of the competitive electricity markets in both the United States and Canada. Marginal decreases in electricity prices resulting from greater choice are also expected, in addition to the price decreases resulting from the efficiency gains. The authors warned that these benefits belong to the theoretical field, as only a small fraction of customers have switched to alternate providers in those jurisdictions where customer choice is allowed. The case of California was discussed, with its greatly increased volatility in wholesale electricity markets to illustrate how price increases have overwhelmed the expected price reductions from increased efficiency. Eight different sections were created in this paper to properly address all the issues. An overview of the current electricity sector, from the perspective of installed capacity, generation and fuel mix in North America was provided in Section One. The environmental context of electricity generation, with the focus on criteria air pollutants and non-air environmental impacts was discussed in Section Two. The various scenarios concerning electricity supply and demand, with forecasts to 2010 and 2020 were included in Section Three, in addition to a discussion related to New Generating capacity data to 2007. Possible environmental impacts of this new generating capacity was examined in Section Four, while in Section

    Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of morbidity and mortality in developed countries. The management of blood cholesterol through use of 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitors (statins) in at-risk patients is a pillar of medical therapy for the primary and secondary prevention of cardiovascular disease. The recent 2013 American College of Cardiology/American Heart Association guideline on managing blood cholesterol provides an important framework for the effective implementation of risk-reduction strategies. The guideline identifies four cohorts of patients with proven benefits from statin therapy and streamlines the dosing and monitoring recommendations based on evidence from published, randomized controlled trials. Primary care physicians and cardiologists play key roles in identifying populations at elevated ASCVD risk. In providing a practical management overview of the current blood cholesterol guideline, we facilitate more informed discussions on treatment options between healthcare providers and their patients.

    Micro-air vehicles (MAVs) have attracted attention for their potential application to military applications, environmental sensing, and search and rescue missions. While progress is being made toward fabrication of a completely human-engineered MAV, another promising approach seeks to interface to, and take control of, an insect's nervous system. Cyborg insects take advantage of their innate exquisite loco-motor, navigation, and sensing abilities. Recently, several groups have demonstrated the feasibility of radio-controlled flight in the hawkmoth and beetle via electrical neural interfaces. Here, we report a method for eliciting the "jump" response in the American grasshopper (S. Americana). We found that stimulating the metathoracic T3 ganglion with constant-current square wave pulses with amplitude 186 ± 40 μA and frequency 190 ± 13 Hz reproducibly evoked (≥95% success rate) the desired motor activity in N=3 test subjects. To the best of our knowledge, this is the first report of an insect cyborg with a synchronous neuromuscular system.

    In July 2011, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, completed a geophysical survey using electrical resistivity along an approximately 6-mile reach of the lower American River in Sacramento, California, to map near-surface lithological variations. This survey is a part of a manifold and comprehensive study of river-flow dynamics and geologic boundary-property knowledge necessary to estimate scour potential and levee erosion risk. Data were acquired on the left (south or west) bank between river mile 5 and 10.7 as well as a short section on the right bank from river mile 5.4 to 6. Thirteen direct-current resistivity profiles and approximately 8.3 miles of capacitively coupled resisistivity data were acquired along accessible areas of the floodplain between the levee and river bank. Capacitively coupled resistivity was used as a reconnaissance tool, because it allowed for greater spatial coverage of data but with lower resolution and depth of investigation than the DC resistivity method. The study area contains Pleistocene-age alluvial deposits, dominated by gravels, sands, silts, and clays, that vary in both lateral extent and depth. Several generations of lithologic logs were used to help interpret resistivity variations observed in the resistivity models.

    Co-operation between industrial autoproducers and the public utilities has a long tradition in Germany. This is particularly the case in combined heat and power generation. In 1993 electricity supplied by third parties contributed with approximately 14% to electricity demand coverage. This is (as in Italy) the next highest proportion in the EU. In 1994 the industry's associations -BDI, VIK and VDEW - agreed upon new remuneration models for electricity supplied by combined heat and power stations and plants on the basis of renewable energies. Additionally, principles agreed upon in 1979 were further developed. (orig.) [de

  15. The diverse strategies of american electricity companies in the face of de-monopolization of the electricity market

    2000-01-01

    The electricity boards in the United States of America have adopted new strategies clearly influenced by anterior regulations and by de-monopolization. Numerous mergers are only the most spectacular of these strategies, enabling the start-up handicap of size in face of new competition to be surmounted, and offering the advantage of bringing together the supply of gas and electricity. Two principal means of adaptation for the gas and electricity boards are their development in non-regulated production (equipment sharing, setting up of merchant plants), and their involvement in bulk trade and competitive retail sales; moreover some choose to specialize in electronuclear production on transport. Lastly, internationalization and diversification towards telecommunications are more frequent there than elsewhere. The purpose of this article is to characterize these strategies in comparison with those of the European electricity companies

    The population genetics and systematics of most coccidians remain poorly defined despite their impact on human and veterinary health. Non-recombinant parasite clones characterized by distinct transmission and pathogenesis traits persist in the coccidian Toxoplasma gondii despite opportunities for sexual recombination. In order to determine whether this may be generally true for tissue-cyst forming coccidia, and to address evolutionary and taxonomic problems within the genus Sarcocystis, we characterized polymorphic microsatellite markers in Sarcocystis neurona, the major causative agent of equine protozoal myeloencephalitis (EPM). Bayesian statistical modeling, phylogenetic reconstruction based on genotypic chord distances, and analyses of linkage disequilibrium were employed to examine the population structure within S. neurona and closely related Sarcocystis falcatula isolates from North and South America. North American S. neurona were clearly differentiated from those of South America and also from isolates of S. falcatula. Although S. neurona is characterized by substantial allelic and genotypic diversity typical of interbreeding populations, one genotype occurs with significantly excessive frequency; thus, some degree of asexual propagation of S. neurona clones may naturally occur. Finally, S. neurona isolated from disparate North American localities and diverse hosts (opossums, a Southern sea otter, and horses) comprise a single genetic population. Isolates associated with clinical neurological disease bear no obvious distinction as measured by these presumably neutral genetic markers.

    Worldwide electricity sector reforms open up electricity markets and increase trades. This has environmental consequences as exports and imports either increase or decrease local production and consequently greenhouse gas (GHG) emissions. This paper's objective is to illustrate the importance of electricity trade's impact on GHG emissions by providing an estimate of the net GHG emissions resulting from these trades. To achieve this objective, Quebec hourly electricity exchanges with adjacent jurisdictions were examined over the 2006-2008 period. In order to associate a specific GHG emission quantity to electricity trades, hourly marginal electricity production technologies were identified and validated using the Ontario hourly output per power plant and information released in the Quebec adjacent system operator reports. It is estimated that over three years, imports into Quebec were responsible for 7.7 Mt of GHG, while Quebec hydropower exports avoided 28.3 Mt of GHG emissions. Hence, the net result is 20.6 Mt of avoided emissions over 2006-2008, or about 7 Mt per year, which corresponds to more than 8% of the Quebec yearly GHG emissions. When GHG emissions from all life cycle stages (resource extraction to end-of-life) are accounted for, the net avoided GHG emissions increase by 35%, to 27.9 Mt. - Research highlights: → Environmental benefits of hydropower exports are considerable. → Detailed GHG assessment of such electricity trade is missing from the literature. → Net GHG emissions estimate resulting from such trade is provided. → GHG gains are significant in the Northeast American electricity market due to such electricity trade.

    In the past, victims of electrical and lightning injuries have been assessed in a manner lacking a systematic formulation, and against ad hoc criteria, particularly in the area of neuropsychological disability. In this manner patients have, for example, only been partially treated, been poorly or incorrectly diagnosed, and have been denied the full benefit of compensation for their injuries. This paper contains a proposal for diagnostic criteria particularly for the neuropsychological aspects of the post injury syndrome. It pays attention to widely published consistent descriptions of the syndrome, and a new cluster analysis of post electrical injury patients. It formulates a proposal which could be incorporated into future editions of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM). The major neuropsychological consequences include neurocognitive dysfunction, and memory subgroup dysfunction, with ongoing consequences, and sometimes including progressive or delayed psychiatric, cognitive, and/or neurological symptoms. The proposed diagnostic criteria insist on a demonstrated context for the injury, both specifying the shock circumstance, and also physical consequences. It allows for a certain delay in onset of symptoms. It recognizes exclusory conditions. The outcome is a proposal for a DSM classification for the post electrical or lightning injury syndrome. This proposal is considered important for grounding patient treatment, and for further treatment trials. Options for treatment in electrical or lightning injury are summarised, and future trials are foreshadowed.

  20. Assessment and evolution of renewable energy policy: the transition of the Latin-American electricity sectors

    International Nuclear Information System (INIS)

    Bersalli, German

    2017-01-01

    The transition to a more sustainable energy system requires a much faster development of new and renewable energy technologies for electricity generation (RENe). Thus, involving new challenges in the regulation of electricity sector. Additionally, a stronger commitment by emerging and developing countries for a deeper decarbonization trajectory, calls for the strengthening of renewable energy policies. Such policies include designing regulatory instruments that are better adapted for their specific economic and institutional needs. This thesis deals with the evaluation and the redesign of policies that encourage the diffusion of RENe in the context of Latin America's countries. To this end, we first use Environmental Economics theory to analyse the different regulatory instruments available, characterize them and to propose evaluation criteria based on a thorough review of the literature. We then carry out a panel data econometric study, to identify the determining factors of investments in regards to new RENe production capacity; and in particular, to measure the effectiveness of such policies. In a third phase, we mobilize the evolutionary theory of technological change to analyse the process of policy implementation, the existing barriers and the obtained results. This analysis is based on three case studies in the electricity sector of Chile, Brazil and Argentina. And finally, we focus on the challenges related to the massive deployment of RENe in Latin America by 2030-2040: the integration of intermittent energy sources, the access to financing and the industrial challenge. Our research shows that the evolution of the economic and institutional context encourages a dynamic which conditions public policy choices as well as their performance. We therefore propose the basis of an analytical framework for the design and assessment of ambitious long-term promoting policies. These policies must be integrated into a multidimensional and coherent project for the

    2009-08-01

    Aimed at obtaining complete and highly accurate potential energy surfaces for molecules containing heavy elements, we present a new general-order coupled cluster method which can be applied in the framework of the spin-free Dirac formalism. As an initial application we present a systematic study of electron correlation and relativistic effects on the spectroscopic and electric properties of the LiCs molecule in its electronic ground state. In particular, we closely investigate the importance of excitations higher than coupled cluster doubles, spin-free and spin-dependent relativistic effects and the correlation of outer-core electrons on the equilibrium bond length, the harmonic vibrational frequency, the dissociation energy, the dipole moment and the static electric dipole polarizability. We demonstrate that our new implementation allows for highly accurate calculations not only in the bonding region but also along the complete potential curve. The quality of our results is demonstrated by a vibrational analysis where an almost complete set of vibrational levels has been calculated accurately.

    North America produces and uses over 50 per cent of the electricity in the industrialized world. Regulatory trends in Mexico, the United States and Canada converge toward the opening up of electricity markets, while regional trade of electricity across national borders is being encouraged. Fundamental questions remain concerning the effects on the natural air-water-and-land environment in all three countries and the manner in which this trade occurs. Public health is also a factor to be considered. Some government intervention is required, was the general consensus arrived at at the symposium organized by the Commission for Environmental Cooperation of North America (CEC). This intervention should probably take the form of emission standards, transparent regulatory hearings and efforts to render the rules in the three countries more compatible. Demand growth and the incorporation of pollution controls will require some private investment. The author indicated that the symposium participants recognized that the reconciliation of an efficient continental electricity market with environmental goals will come with improving the efficiency with which North Americans use energy. refs., 1 tab., 1 fig

  5. Electricity sector reforms in four Latin-American countries and their impact on carbon dioxide emissions and renewable energy

    2010-01-01

    This paper analyzes carbon dioxide (CO 2 ) emissions related to energy consumption for electricity generation in four Latin-American countries in the context of the liberalization process. From 1990 to 2006, power plants based on renewable energy sources decreased its share in power installed capacity, and the carbon index defined as CO 2 emission by unit of energy for electricity production stayed almost constant for all countries with the exception of Colombia, where the index reduced due to increase in hydroelectricity generation in the last years. The paper also presents a new set of policies to promote renewable energy sources that have been developed in the four countries. The paper concludes that restructuring did not bring about environmental benefits related to a decrease in CO 2 emissions because this depend on the existence of committed policies, and dedicated institutional and regulatory frameworks.

    Canada, Mexico, and the United States commented in turn on the issues related to the integration of the North American electricity market. Canada indicated that the report was based on on specific sets of data, analyses, and several assumptions. It provides a starting point for further discussions as information and analyses are further improved. Four categories of issues were identified: transboundary airshed management, innovative economic instruments, energy efficiency and renewable energy, and information planning and transboundary cumulative impact assessment. Some of those areas are already the subject of improved cooperation. Mexico mentioned that the major problem was one of pollution in geographically shared but jurisdictionally divided regions. This situation could lead to preferences in the selection of locations for power generation plants, as environmental rules differ. The suggestions made in the report do not always reflect the approaches being discussed in Mexico. Some specific comments about the various working papers were offered. The United States stated that the report provides a solid foundation for further discussions on the topic. The United States also indicated that further qualification, analysis, and/or discussion is required on some important issues. It felt that the future growth, continental-scale integration, and environmental impacts related to the electricity sector had been overestimated. More comprehensive comparisons between the three countries would benefit the entire process. More specific comments were included

  8. Power Struggle: Changing Momentum in the Restructured American Electric Utility System

    2004-01-01

    Since the 1970's, producing and distributing electricity were considered as a natural monopoly. They were subjected to state regulation meant to defend the consumers' interest but which in reality enhanced the power of utility managers. The changes that happened since questioned the managers' control over the system. Following the technological stasis that occurred in the production of electricity, the oil crisis, and the awakening of the environmental movement, the Government adopted the Public Utility Regulatory Policies Act in 1978, favoring the coming of cogeneration technologies benefiting the small producers. Market economy tended to replace natural monopoly. Deregulation became a valuable option and was stimulated by the 1992 Energy Policy Act. However, the electrical crisis in California and the recent blackout over part of the continent slowed down the pace of the change

    1984-01-01

    This chapter compares the current and historic operating performances of twelve large nuclear and coal-fired units now operated by Commonwealth Edison Company, and provides specific comparison of bus-bar costs of electricity generated by those units in recent years. It also provides cost comparisons for future nuclear and coal-fired units and attempts to deal realistically with the effect of future inflation upon these comparisons. The chapter attempts to deal responsibly with the problem of uncertainty - how present-day comparisons may be affected by future developments and how my own published comparisons have varied over the past four or five years. The conclusion is reached that, given the uncertain world in which we live, no electric power supplier can afford to put all its eggs in one basket. Utility managers have a strong incentive to diversify their sources of power generation, and society as a whole would do well to encourage such diversification. (author)

    ALSTOM Power Inc.'s Power Plant Laboratories (ALSTOM) has teamed with American Electric Power (AEP), ABB Lummus Global Inc. (ABB), the US Department of Energy National Energy Technology Laboratory (DOE NETL), and the Ohio Coal Development Office (OCDO) to conduct a comprehensive study evaluating the technical feasibility and economics of alternate CO{sub 2} capture and sequestration technologies applied to an existing US coal-fired electric generation power plant. The motivation for this study was to provide input to potential US electric utility actions concerning GHG emissions reduction. If the US decides to reduce CO{sub 2} emissions, action would need to be taken to address existing power plants. Although fuel switching from coal to natural gas may be one scenario, it will not necessarily be a sufficient measure and some form of CO{sub 2} capture for use or disposal may also be required. The output of this CO{sub 2} capture study will enhance the public's understanding of control options and influence decisions and actions by government, regulators, and power plant owners in considering the costs of reducing greenhouse gas CO{sub 2} emissions. The total work breakdown structure is encompassed within three major reports, namely: (1) Literature Survey, (2) AEP's Conesville Unit No.5 Retrofit Study, and (3) Bench-Scale Testing and CFD Evaluation. The report on the literature survey results was issued earlier by Bozzuto, et al. (2000). Reports entitled ''AEP's Conesville Unit No.5 Retrofit Study'' and ''Bench-Scale Testing and CFD Evaluation'' are provided as companion volumes, denoted Volumes I and II, respectively, of the final report. The work performed, results obtained, and conclusions and recommendations derived therefrom are summarized.

    Full Text Available Background: Cerebral palsy is the leading cause of physical disability in pediatric  age. The search for new methods and improvement of old rehabil- itation techniques is ongoing, due to low efficacy of the latter. Aim: To assess the efficacy of a func- tional programmed electrical muscle stimulation as a part  of combination treatment of patients with cerebral palsy in the form of spastic diplegia. Materials and methods: We analyzed the results of treatment of 71 children with cerebral palsy and spastic diplegia, who had  been  randomized  into two groups  depending on the type of treatment. In  the  first group,  the  patients  (n = 38 received a course of functional programmed electric stim- ulation  in combination with  other  non-medical treatment  methods.  The  second   group   (n = 33 underwent a usual  course  of electrical  stimula- tion in combination with non-medical  treatment, similar to that  in the first group. The third group (control   included   41   children   without    cere- bral palsy. Clinical and  instrumental parameters were  assessed  in all study  participants. Results: After the course of combination treatment in the group  1, the  tonus  of m. gastrocnemius was de- creased significantly by 41%, that of the posterior group  of femur muscles by 43%, adductor group of femur muscles by 36%. In the group  2, the re- spective parameters decreased by 24, 21 and 21%. Muscle power  endurance was  increased  signifi- cantly in patients of both groups: that of long back extensors by 12.5 and 6.2 sec, of m. rectus abdomi- nis by 10.6 sec and 5.2 sec, of gluteal muscles by 9.3 and 4.6 sec, of m. quadriceps  by 19.8 and 7.2 sec, of m. anterior  tibialis by 12.1 and 4.6 sec, respec- tively. After the  treatment, the  active movement volume in the large joints of lower extremities  in the group 1 patients  improved as follows: by 15.6° in hip joints, by 11.1° in knee joints and by

  20. High thermal performance lithium-ion battery pack including hybrid active–passive thermal management system for using in hybrid/electric vehicles

    Fathabadi, Hassan

    2014-01-01

    In this study, a novel Li-ion battery pack design including hybrid active–passive thermal management system is presented. The battery pack is suitable for using in hybrid/electric vehicles. Active part of the hybrid thermal management system uses distributed thin ducts, air flow and natural convection as cooling media while the passive part utilizes phase change material/expanded graphite composite (PCM/EG) as cooling/heating component to optimize the thermal performance of the proposed battery pack. High melting enthalpy of PCM/EG composite together with melting of PCM/EG composite at the temperature of 58.9 °C remains the temperature distribution of the battery units in the desired temperature range (below 60 °C). The temperature and voltage distributions in the proposed battery pack design consisting of battery units, distributed thin ducts and PCM/EG composite are calculated by numerical solving of the related partial differential equations. Simulation results obtained by writing M-files code in Matlab environment and plotting the numerical data are presented to validate the theoretical results. A comparison between the thermal and physical characteristics of the proposed battery pack and other latest works is presented that explicitly proves the battery pack performance. - Highlights: • Novel Li-ion battery pack including active and passive thermal management systems. • The battery pack has high thermal performance for ambient temperatures until 55 °C. • Uniform temperature and voltage distributions. • The maximum observed temperature in each battery unit is less than other works. • The maximum temperature dispersion in each battery is less than other works

  1. A coordinated study of a storm system over the South American continent. 1. Weather information and quasi-DC stratospheric electric field data

    This paper reports on a coordinated campaign conducted in Brazil, December 13, 1989, to study the electrical signatures associated with a large storm system over the South American continent. Inside the storm, large convective cells developed extending up to the tropopause, as revealed from meteorological balloon soundings. Quasi-DC vertical electric field and temperature were measured by zero-pressure balloon-borne payload launched from Cachoeira Paulista, Brazil. The data were supported by radar and GOES satellite observations, as well as by a lightning position and tracking system (LPATS). The analysis of infrared imagery supports the general tendency for lightning strikes to be near to but not exactly under the coldest cloud tops. In turn, the radar maps located the strikes near to but outside of the most intense areas of precipitation (reflectivity levels above 40 dBz). The balloon altitude and stratospheric temperature show significant variations in association with the storm. The quasi-DC vertical electric field remained almost during the whole flight in a reversed direction relative to the usual fair weather downward orientation with values as large as 4 V/m. A simple calculation based on a static dipole model of electrical cloud structure gives charges of some tens of coulombs. In contrast with most electric field measurements in other regions, no indication of an intensification of the vertical field in the downward fair weather orientation was observed. This fact is in agreement with past observations in the South American region and seems to be related to a particular type of storm that would occur with more frequency in this region. If so, such a difference may have an important role in the global atmospheric electrical circuit, considering that South America is believed to give a significant current contribution to the global circuit.

    2002-06-01

    Several factors are affecting power generating facilities, such as the opening of both electricity and gas markets, and the pressure applied on generators and governments to ensure a steady energy supply for consumers. An additional factor is the pressure for the closing of nuclear power facilities. European siting and emissions requirements for coal-fired and natural gas generating facilities were presented in this background paper. In addition, the author provided an overview of the standardization process in place in Europe. The European Union and its functioning were briefly described, as well as a listing of relevant organizations. The current trends were examined. The document first introduced the European Union, and the next section dealt with Regulatory regime: the internal energy market. The third section examined the issue of Regulatory regime: generation and environmental regulations. Section four presented environmental management systems, followed by a section on standardization. Section six discussed European organizations involved in electricity issues, while the following section dealt with European commission programs. The last section briefly looked at the trends in the electricity sector, broaching topics such as compliance, electricity generation, and emissions trading. 52 refs., 2 tabs

  6. Geothermal energy for American Samoa

    Energy Technology Data Exchange (ETDEWEB)

    1980-03-01

    The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and transhipment refrigerated warehouses, electric cars, ocean nodule processing, and a hydrogen economy. There are no territorial statutory laws of American Samoa claiming or reserving any special rights (including mineral rights) to the territorial government, or other interests adverse to a land owner, for subsurface content of real property. Technically, an investigation has revealed that American Samoa does possess a geological environment conducive to geothermal energy development. Further studies and test holes are warranted.

    Over the past three decades industrial consolidation has been a global, dominating mega-trend, and this also holds for the energy sector. The drivers behind this phenomenon are market liberalisation and privatisation. These transformation processes have created new growth opportunities for energy supply companies such as the development of markets in emerging countries. How have Latin American countries such as Argentina, Brazil or Chile succeeded in opening their markets to international investors and what has been the impact of acquisition activities by companies in the electricity and gas sector?.

    2000-01-01

    The observed sharp increase in the number of childhood-thyroid-cancer cases in Belarus that has occurred since the Chernobyl accident stimulated the undertaking in 1994 of a long-term American-Belarusian cohort study. That epidemiological study is aimed at revealing the carcinogenic effectiveness of 131 I (the main contributor to the thyroid exposure) and at estimating the risk coefficient of thyroid disease, especially thyroid cancer, as a function of age at exposure. It is planned to follow actively 15,000 children (aged 0-18 at the time of the accident) sampled among about 40,000 who had their thyroid measured in vivo in 1986. Such direct thyroid measurements provide the basis for the initial thyroid dose estimates that have been established for the 40,000 children in the absence of personal interviews. As of August 1999, approximately 5,000 cohort subjects have been screened and interviewed. The initial estimates of individual thyroid dose are being revised for all of the cohort subjects that have been screened. The revision procedure of the 131 I thyroid dose assessment consists of two parts: (1) re-analysis of the direct thyroid measurements and (2) analysis of the responses to the personal interview which were conducted in order to determine the kinetics of the radioiodine intake by the cohort subjects. Revised estimates of thyroid dose resulting from 131 I intake are presented for a sample of 1,000 subjects residing in various areas of Belarus. The reason for the differences between the initial and the revised thyroid dose estimates are discussed. In addition to the estimation of the internal thyroid dose from 131 I, three minor contributors to the thyroid exposure are considered separately: (1) the internal exposure resulting from intake of short-lived radioiodines and radiotelluriums, (2) the internal exposure resulting from intake of other radionuclides (mainly radiocesiums), and (3) external exposure from radionuclides deposited on the ground.

    2017-11-01

    The paper presents multicriteria decision aid analysis of the choice of PV installation providing electric energy to a public utility building. From the energy management point of view electricity obtained by solar radiation has become crucial renewable energy source. Application of PV installations may occur a profitable solution from energy, economic and ecologic point of view for both existing and newly erected buildings. Featured variants of PV installations have been assessed by multicriteria analysis based on ANP (Analytic Network Process) method. Technical, economical, energy and environmental criteria have been identified as main decision criteria. Defined set of decision criteria has an open character and can be modified in the dialog process between the decision-maker and the expert - in the present case, an expert in planning of development of energy supply systems. The proposed approach has been used to evaluate three variants of PV installation acceptable for existing educational building located in Poznań, Poland - the building of Faculty of Chemical Technology, Poznań University of Technology. Multi-criteria analysis based on ANP method and the calculation software Super Decisions has proven to be an effective tool for energy planning, leading to the indication of the recommended variant of PV installation in existing and newly erected public buildings. Achieved results show prospects and possibilities of rational renewable energy usage as complex solution to public utility buildings.

    The paper considers the Anti-lock Braking System (ABS) operation algorithm, which enables the implementation of hybrid braking, i.e. the braking process combining friction brake mechanisms and e-machine (electric machine), which operates in the energy recovery mode. The provided materials focus only on the rectilinear motion of the vehicle. That the ABS task consists in the maintenance of the target wheel slip ratio, which depends on the tyre-road adhesion coefficient. The tyre-road adhesion coefficient was defined based on the vehicle deceleration. In the course of calculated studies, the following operation algorithm of hybrid braking was determined. At adhesion coefficient ≤0.1, driving axle braking occurs only due to the e-machine operating in the energy recovery mode. In other cases, depending on adhesion coefficient, the e-machine provides the brake torque, which changes from 35 to 100% of the maximum available brake torque. Virtual tests showed that values of the wheel slip ratio are close to the required ones. Thus, this algorithm makes it possible to implement hybrid braking by means of the two sources creating the brake torque.

    A substantial contribution to the electricity supply of North America can be made by renewable energy. Its uses range from transport fuels based on biomass, to space and hot water heating in buildings and industry. Two possible options are distributed forms of renewable energy and central large-scale technology. Significant employment opportunities could be created from the manufacturing, installation and maintenance of renewable technology. In Mexico, the United States and Canada, rural economic development could be enhanced through the use of wind and biomass fuels. Every three years between 1994 and 2001, wind power installations doubled, and a comparable rate was achieved for the period 1996 to 2001 in the case of photovoltaic shipments. North America's share of this accelerating market in renewable energy sources is declining. To rectify the situation, the author indicated that several issues need to be addressed in all three countries and the trading rules in place under the North American Free Trade Agreement (NAFTA) need to be reconciled. Several recommendations were made concerning topics as varied as general policy principles to promote renewable technology, establishment of incentives for renewables, renewable electricity, biomass fuels, economic and social policies, research and development and purchasing. 30 refs

    South America combines economic and population growth with a consequent rapid increase in electricity demand. This can only be covered by building new power plants, use of the remaining renewable potential and expansion of transmission lines. The expansion of supply in all regions, with reliable generation and transmission systems is the greatest challenge for the continent in order to reduce social differences and not to curb economic development. To support the energy planning the application of system models represents useful method. This paper intends to analyze the expansion effect of power plant parks in regard of greenhouse gases emissions using a regionalized model system 'TIMES (The Integrated Markal - EFOM System)'. The model includes 10 South American countries (Argentina, Brazil, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay and Venezuela) with their respective power parks and transmission lines, demand divided in sectors, potential use of renewable energy sources, gas pipelines and possibilities of new interconnections within and between countries. As results are obtained the future installed capacity and generation according the energy use, greenhouse gases emissions, as well as the investments needed to expand the electric system in different scenarios.

    Ayahuasca, a South American psychotropic plant tea obtained from Banisteriopsis caapi and Psychotria viridis, combines monoamine oxidase-inhibiting beta-carboline alkaloids with N,N-dimethyltryptamine (DMT), a psychedelic agent showing 5-HT(2A) agonist activity. In a clinical research setting, ayahuasca has demonstrated a combined stimulatory and psychedelic effect profile, as measured by subjective effect self-assessment instruments and dose-dependent changes in spontaneous brain electrical activity, which parallel the time course of subjective effects. In the present study, the spatial distribution of ayahuasca-induced changes in brain electrical activity was investigated by means of low-resolution electromagnetic tomography (LORETA). Electroencephalography recordings were obtained from 18 volunteers after the administration of a dose of encapsulated freeze-dried ayahuasca containing 0.85 mg DMT/kg body weight and placebo. The intracerebral power density distribution was computed with LORETA from spectrally analyzed data, and subjective effects were measured by means of the Hallucinogen Rating Scale (HRS). Statistically significant differences compared to placebo were observed for LORETA power 60 and 90 min after dosing, together with increases in all six scales of the HRS. Ayahuasca decreased power density in the alpha-2, delta, theta and beta-1 frequency bands. Power decreases in the delta, alpha-2 and beta-1 bands were found predominantly over the temporo-parieto-occipital junction, whereas theta power was reduced in the temporomedial cortex and in frontomedial regions. The present results suggest the involvement of unimodal and heteromodal association cortex and limbic structures in the psychological effects elicited by ayahuasca. Copyright 2004 S.

    Autonomous twitch elicitation at myofascial trigger points from spondylotic radiculopathies-induced denervation supersensitivity can provide favourable pain relief using electrical twitch-obtaining intramuscular stimulation (ETOIMS). To provide objective evidence that ETOIMS is safe and efficacious in migraine and persistent pain management due to decades-old injuries to head and spine from paediatric American football. An 83-year-old mildly hypertensive patient with 25-year history of refractory migraine and persistent pain self-selected to regularly receive fee-for-service ETOIMS 2/week over 20 months. He had 180 sessions of ETOIMS. Pain levels, blood pressure (BP) and heart rate/pulse were recorded before and immediately after each treatment alongside highest level of clinically elicitable twitch forces/session, session duration and intervals between treatments. Twitch force grades recorded were from 1 to 5, grade 5 twitch force being strongest. Initially, there was hypersensitivity to electrical stimulation with low stimulus parameters (500 µs pulse-width, 30 mA stimulus intensity, frequency 1.3 Hz). This resolved with gradual stimulus increments as tolerated during successive treatments. By treatment 27, autonomous twitches were noted. Spearman's correlation coefficients showed that pain levels are negatively related to twitch force, number of treatments, treatment session duration and directly related to BP and heart rate/pulse. Treatment numbers and session durations directly influence twitch force. At end of study, headaches and quality of life improved, hypertension resolved and antihypertensive medication had been discontinued. Using statistical process control methodology in an individual patient, we showed long-term safety and effectiveness of ETOIMS in simultaneous diagnosis, treatment, prognosis and prevention of migraine and persistent pain in real time obviating necessity for randomised controlled studies.

    The electric communication signals of weakly electric ghost knifefishes (Gymnotiformes: Apteronotidae) provide a valuable model system for understanding the evolution and physiology of behavior. Apteronotids produce continuous wave-type electric organ discharges (EODs) that are used for electrolocation and communication. The frequency and waveform of EODs, as well as the structure of transient EOD modulations (chirps), vary substantially across species. Understanding how these signals have evolved, however, has been hampered by the lack of a well-supported phylogeny for this family. We constructed a molecular phylogeny for the Apteronotidae by using sequence data from three genes (cytochrome c oxidase subunit 1, recombination activating gene 2, and cytochrome oxidase B) in 32 species representing 13 apteronotid genera. This phylogeny and an extensive database of apteronotid signals allowed us to examine signal evolution by using ancestral state reconstruction (ASR) and phylogenetic generalized least squares (PGLS) models. Our molecular phylogeny largely agrees with another recent sequence-based phylogeny and identified five robust apteronotid clades: (i) Sternarchorhamphus+Orthosternarchus, (ii) Adontosternarchus, (iii) Apteronotus+Parapteronotus, (iv) Sternarchorhynchus, and (v) a large clade including Porotergus, 'Apteronotus', Compsaraia, Sternarchogiton, Sternarchella, and Magosternarchus. We analyzed novel chirp recordings from two apteronotid species (Orthosternarchus tamandua and Sternarchorhynchus mormyrus), and combined data from these species with that from previously recorded species in our phylogenetic analyses. Some signal parameters in O. tamandua were plesiomorphic (e.g., low frequency EODs and chirps with little frequency modulation that nevertheless interrupt the EOD), suggesting that ultra-high frequency EODs and "big" chirps evolved after apteronotids diverged from other gymnotiforms. In contrast to previous studies, our PGLS analyses using the

    The objective of this study is to analyse how the use of biomass may increase in the next 10-20 years in production of heat, electricity and transportation fuels in Sweden. In these analyses, the biomass is assumed to be used in a resource and cost efficient way. This means for example that the demand for heat determines the potential use of biomass in co-generation of heat and electricity and in energy combines, and that the markets for by-products determine the use of biomass in production of certain transportation fuels. The economic conditions are not analysed in this study. In the heat and electricity production sector, we make regional analyses of the potential use of biomass in production of small-scale heat, district heat, process heat in the forest industry and electricity produced in co-generation with heat in the district heating systems and forest industry. These analyses show that the use of biomass in heat and electricity production could increase from 87 TWh (the use in 2004/2005, excluding small-scale heat production with firewood) to between 113 TWh and 134 TWh, depending on the future expansion of the district heating systems. Geographically, the Stockholm province accounts for a large part of the potential increase owing to the great opportunities for increasing the use of biomass in production of district heat and CHP in this region. In the sector of transportation fuels we applied a partly different approach since we consider the market for biomass-based transportation fuels to be 'unconstrained' within the next 10-20 years. Factors that constrain the production of these fuels are instead the availability of biomass feedstock and the local conditions required for achieving effective production systems. Among the first generation biofuels this report focuses on RME and ethanol from cereals. We estimate that the domestic production of RME and ethanol could amount to up to 1.4 TWh/y and 0.7-3.8 TWh/y, respectively, where the higher figure

    2011-01-15

    Detailed calculations of the power system in Scandinavia and Germany in 2020 are made, including the countries' known and specific plans for CO{sub 2} reduction and increased use of renewable energy. The calculations analyzed three scenarios for how increased electric power consumption pulls investments in the power sector by 2020. It is shown that only if the countries through grants schemes and other incentives directly link increased consumption of electricity for electric vehicles with greater demands for investments in renewable energy, the CO{sub 2} emissions from electric vehicles will decrease significantly. Such a direct linkage is assessed not to become the case with the existing frame-work and objectives of the EU countries and Norway. The average of the more detailed calculations show a CO{sub 2} emission from electric cars in 2020 of just 650 g CO{sub 2}/kWh (excluding upstream emissions), which is about 10% lower than previously estimated. Towards 2020 increased efficiency of conventional cars (diesel) will probably be a cheaper way to achieve CO{sub 2} reductions in the transport sector than through an expansion with a larger number of electric cars. If oil prices rise to around $ 150/barrel or more, while the price of batteries for electric vehicles drops significantly in the period, this will result, however, is challenged. The same costs are assumed for development and production of diesel and electric cars. For electric cars there will be additional costs for batteries and charging infrastructure. The on manufacturers' pricing strategies for different types of cars have not been considered. The report demonstrates that it will very likely be more expensive to reduce CO{sub 2} emissions from transport compared with, for example the costs in electric power and heat producing sectors that are subject to EU quota system. It can therefore be considered whether a larger part of the EU's reduction goals in the next 10-20 years should be

    2000-07-01

    The Public Interest Advocacy Centre (PIAC), located in Ottawa, participates in regulatory proceedings concerning electricity and natural gas to support public and consumer interest. PIAC provides legal representation, research and policy support and public advocacy. A study aimed toward the determination of the issues at stake for residential electricity consumers in the provision of fair and accurate electricity metering, was commissioned by Measurement Canada in consultation with Industry Canada's Consumer Affairs. The metering of electricity must be carried out in a fair and efficient manner for all residential consumers. The Electricity, Gas and Inspection Act was developed to ensure compliance with standards for measuring instrumentation. The accurate metering of electricity through the distribution systems for electricity in Canada represents the main focus of this study and report. The role played by Measurement Canada and the increased efficiencies of service delivery by Measurement Canada or the changing of electricity market conditions are of special interest. The role of Measurement Canada was explained, as were the concerns of residential consumers. A comparison was then made between the interests of residential consumers and those of commercial and industrial electricity consumers in electricity metering. Selected American and Commonwealth jurisdictions were reviewed in light of their electricity metering practices. A section on compliance and conflict resolution was included, in addition to a section on the use of voluntary codes for compliance and conflict resolution

    The purpose of this project was for Seeo to deliver the first ever large-scale or grid-scale prototype of a new class of advanced lithium-ion rechargeable batteries. The technology combines unprecedented energy density, lifetime, safety, and cost. The goal was to demonstrate Seeo’s entirely new class of lithium-based batteries based on Seeo’s proprietary nanostructured polymer electrolyte. This technology can enable the widespread deployment in Smart Grid applications and was demonstrated through the development and testing of a 10 kilowatt-hour (kWh) prototype battery system. This development effort, supported by the United States Department of Energy (DOE) enabled Seeo to pursue and validate the transformational performance advantages of its technology for use in grid-tied energy storage applications. The focus of this project and Seeo’s goal as demonstrated through the efforts made under this project is to address the utility market needs for energy storage systems applications, especially for residential and commercial customers tied to solar photovoltaic installations. In addition to grid energy storage opportunities Seeo’s technology has been tested with automotive drive cycles and is seen as equally applicable for battery packs for electric vehicles. The goals of the project were outlined and achieved through a series of specific tasks, which encompassed materials development, scaling up of cells, demonstrating the performance of the cells, designing, building and demonstrating a pack prototype, and providing an economic and environmental assessment. Nearly all of the tasks were achieved over the duration of the program, with only the full demonstration of the battery system and a complete economic and environmental analysis not able to be fully completed. A timeline over the duration of the program is shown in figure 1.

    2003-01-01

    This publication contains data on prices of electric energy and transmission of electricity valid from 1 January 2003. The purpose is to illustrate the price changes on the electricity market in terms of prices for different customer categories. All companies holding network concessions for areas and all companies trading in electricity are included in this report, which is produced on an annual basis.The prices for transmission services 1 January 2003 were on the whole unchanged compared to the preceding year. For households the mean annual cost was SEK 882 for flats, SEK 4 335 for one- or two-family houses with electric heating and SEK 1 925 for those without electric heating. Electricity prices rose considerably on 1 January 2003 compared to the year before. The mean price per kWh for households with standard agreements was SEK 0.519 for deliveries to flats, SEK 0.447 for one- or two-family houses with electric heating and SEK 0.471 without electric heating. As a result, the mean annual cost increased by SEK 326 for flats, SEK 3 012 for one- or two-family houses with electric heating, and by SEK 774 for those houses without electric heating. The high costs of electricity may be explained in part by the development on the Nordic Power Exchange (Nord Pool), where the spot price increased by about 290 per cent during 2002 (1 USD is about 8 SEK)

    1991-01-01

    Investigations of the impact of high-altitude electromagnetic pulse (HEMP) on electric power systems and electrical equipment have revealed that HEMP creates both misoperation and failures. These events result from both the early time E[sub 1] (steep-front pulse) component and the late time E[sub 3] (geomagnetic perturbations) component of HEMP. In this report a HEMP event is viewed in terms of its marginal impact over classical power system disturbances by considering the unique properties and consequences of HEMP. This report focuses on system-wide electrical component failures and their potential consequences from HEMP. In particular, the effectiveness of planning and operating procedures for electric systems is evaluated while under the influence of HEMP. This assessment relies on published data and characterizes utilities using the North American Electric Reliability Council's regions and guidelines to model electric power system planning and operations. Key issues addressed by the report include how electric power systems are affected by HEMP and what actions electric utilities can initiate to reduce the consequences of HEMP. The report also reviews the salient features of earlier HEMP studies and projects, examines technology trends in the electric power industry which are affected by HEMP, characterizes the vulnerability of power systems to HEMP, and explores the capability of electric systems to recover from a HEMP event.

    Boston, Edwin J., Jr.

    The purpose of this research is to identify the United States electric grid infrastructure systems vulnerabilities to electromagnetic pulse attacks and the cyber-based impacts of those vulnerabilities to the electric grid. Additionally, the research identifies multiple defensive strategies designed to harden the electric grid against electromagnetic pulse attack that include prevention, mitigation and recovery postures. Research results confirm the importance of the electric grid to the United States critical infrastructures system and that an electromagnetic pulse attack against the electric grid could result in electric grid degradation, critical infrastructure(s) damage and the potential for societal collapse. The conclusions of this research indicate that while an electromagnetic pulse attack against the United States electric grid could have catastrophic impacts on American society, there are currently many defensive strategies under consideration designed to prevent, mitigate and or recover from an electromagnetic pulse attack. However, additional research is essential to further identify future target hardening opportunities, efficient implementation strategies and funding resources.

    The first part of the debate, which lasted a total of about 7 hours, a verbatim report of the first five of which are included here, was about energy conservation. Several new clauses and amendments were discussed. One would place a duty on the new Director of the Energy Supply industry to promote the efficiency and conservation of energy, another would appoint a Deputy Director with responsibility for energy conservation, and the third would require targets of energy efficiency and pollution reduction to be achieved. This allowed discussion on energy saving by domestic thermal insulation, improved efficiency of heating and refrigeration units and on renewable energy sources especially world energy. The second part of the debate was about access to information regarding health and safety resulting from any activities of the electricity supply industry. The remainder of the debate concerned regional representation and the economics of the electricity supply industry. (UK)

The Swedish Energy Agency is the supervisory authority specified in the Electricity Act, and one of the tasks entrusted to it by the Government is to follow developments on the electricity market and regularly compile and report current market information. The purpose of 'The Electricity Market 2003' publication is to meet the need for generalized and easily accessible information on the conditions on the Nordic market. The publication also includes summaries of the information from recent years concerning power generation and utilization in the Nordic countries, the structure of the electricity market from the players' perspective, trade in electricity in the Nordic countries and in northern Europe, electricity prices in the Nordic and other countries, and the impact of the electricity sector on the environment

    A nuclear heart pacer having a heat-to-electricity converter including a solid-state thermoelectric unit embedded in rubber which is compressed to impress hydrostatic precompression on the unit is described. The converter and the radioactive heat source are enclosed in a container which includes the electrical circuit components for producing and controlling the pulses; the converter and components being embedded in rubber. The portions of the rubber in the converter and in the container through which heat flows between the radioactive primary source and the hot junction and between the cold junction and the wall of the container are of thermally conducting silicone rubber. The 238 Pu primary radioactive source material is encapsuled in a refractory casing of WC-222 (T-222) which in turn is encapsuled in a corrosion-resistant casing of platinum rhodium, a diffusion barrier separating the WC-222 and the Pt--Rh casings. The Pt--Rh casing is in a closed basket of tantalum. The tantalum protects the Pt--Rh from reacting with other materials during cremation of the host, if any. The casings and basket suppress the transmission of hard x rays generated by the alpha particles from the 238 Pu. The outside casing of the pacer is typically of titanium but its surface is covered by an electrically insulating coating, typically epoxy resin, except over a relatively limited area for effective electrical grounding to the body of the host. It is contemplated that the pacer will be inserted in the host with the exposed titanium engaging a non-muscular region of the body

  9. Electricity and Culture: Conceptualizing the American Case

    International Nuclear Information System (INIS)

    Nye, David

    2004-01-01

    This paper explores three concepts that can be used to understand how particular technologies become predominant in society, using the electrification of the United States as the key example. The first concept, technological momentum, identifies a crucial stage in the development of socio-technical systems. It was first put forward by Thomas P. Hughes in his landmark book, Networks of Power. The second concept, the social construction of technology, maintains that technologies are socially shaped, notably by their social and political contexts and by their consumers. These two concepts are not as far apart as it might appear, however, and can be reconciled. Economic historians developed a third concept, path dependence, without explicit reference to either of these ideas. These theorists seek to explain why some companies and some nations cling to outmoded technological arrangements rather than seek the efficiencies that neoclassical economic theory predicts. This paper will suggest a synthesis of all three ideas, building upon Hughes's theory

    External electrical cardioversion was first performed in the 1950s. Urgent or elective cardioversions have specific advantages, such as termination of atrial and ventricular tachycardia and recovery of sinus rhythm. Electrical cardioversion is life-saving when applied in urgent circumstances. The succcess rate is increased by accurate tachycardia diagnosis, careful patient selection, adequate electrode (paddles) application, determination of the optimal energy and anesthesia levels, prevention of embolic events and arrythmia recurrence and airway conservation while minimizing possible complications. Potential complications include ventricular fibrillation due to general anesthesia or lack of synchronization between the direct current (DC) shock and the QRS complex, thromboembolus due to insufficient anticoagulant therapy, non-sustained VT, atrial arrhythmia, heart block, bradycardia, transient left bundle branch block, myocardial necrosis, myocardial dysfunction, transient hypotension, pulmonary edema and skin burn. Electrical cardioversion performed in patients with a pacemaker or an incompatible cardioverter defibrillator may lead to dysfunction, namely acute or chronic changes in the pacing or sensitivity threshold. Although this procedure appears fairly simple, serious consequences might occur if inappropriately performed. PMID:19448376

    The first book studies on the economics of electricity consumption. Compares the sector production functions with electricity and the commercial production functions with electricity. Introduces the global E-GDP function, the European E-GDP function and 12 national E-GDP functions. Presents the gene characters of EAI production functions and E-GDP functions for USA to see why USA's economy is entering an up-industrialization period. Discusses China's economic growth by production functions with electricity. Electricity Economics: Production Functions with Electricity studies the production output from analyzing patterns of electricity consumption. Since electricity data can be used to measure scenarios of economic performance due to its accuracy and reliability, it could therefore also be used to help scholars explore new research frontiers that directly and indirectly benefits human society. Our research initially explores a similar pattern to substitute the Cobb-Douglas function with the production function with electricity to track and forecast economic activities. The book systematically introduces the theoretical frameworks and mathematical models of economics from the perspective of electricity consumption. The E-GDP functions are presented for case studies of more than 20 developed and developing countries. These functions also demonstrate substantial similarities between human DNA and production functions with electricity in terms of four major characteristics, namely replication, mutation, uniqueness, and evolution. Furthermore, the book includes extensive data and case studies on the U.S., China, Japan, etc. It is intended for scientists, engineers, financial professionals, policy makers, consultants, and anyone else with a desire to study electricity economics as well as related applications.

    2002-01-01

    This publication contains data on prices of electric energy and transmission of electricity valid on 1 January 2002. The purpose is to illustrate the price changes on the electricity market in terms of prices for different customer categories. All companies holding network concessions for areas and all companies trading in electricity are included in this report, which is produced on an annual basis. The prices for transmission services 1 January 2002 were on the whole unchanged compared to the preceding year. For households the mean annual cost was SEK 856 for flats, SEK 4,194 one- or two-family houses with electric heating and SEK 1,881 without electric heating. (1 SEK ∼ 0.1 USD). Electricity prices rose considerably on 1 January 2002 compared to the year before. The mean price per kWh for households according to standard agreement was SEK 0.356 for deliveries to flats, SEK 0.296 for apartments in one- or two-family houses with electric heating and SEK 0.316 without electric heating. That means that the mean annual cost increased by SEK 171 for flats. For one- or two-family houses with electric heating, costs increased by SEK 1,424, and by SEK 379 for those houses without electric heating. The high costs of electricity may be explained in part by the development on the Nordic Power Exchange (Nord Pool), where the spot price increased by 75 per cent during 2001. The price development for household customers during 1996-2002 is shown in a diagram

  2. Pricing electricity for sustainability : climate change and Canada's electricity sector

    International Nuclear Information System (INIS)

    2010-01-01

    The electricity sector is Canada's largest single source of greenhouse gas (GHG) emissions. This paper discussed electricity and carbon pricing approaches to reducing GHG emissions in the electricity sector. An overview of the links between electricity pricing and climate change was presented, and current and emerging trends in electricity pricing related to encouraging energy conservation were reviewed. Market prices and failures were discussed. Approaches to pricing electricity included an increase in block prices; time-of-use prices; demand-side management and energy efficiency; and carbon pricing in Canada and electricity pricing signals. The study showed that several provincial utilities in Canada are experimenting with market-based pricing approaches for electricity and carbon that may help to reduce GHG emissions over time. Concerns over electricity supply and the negative environmental impacts of electricity production may lead to the full social pricing of electricity in some regions of Canada. 46 refs., 3 tabs., 5 figs.

    Following the civil war of 1996–2006, there was a dramatic increase in the labor mobility of young men and the inclusion of young women in formal education, which led to the transformation of the political landscape of rural Nepal. Mobility and schooling represent a level of prestige that rural...... politics. It analyzes how formal education and mobility either challenge or reinforce traditional gendered norms which dictate a lowly position for young married women in the household and their absence from community politics. The article concludes that women are simultaneously excluded and included from...... community politics. On the one hand, their mobility and decision-making powers decrease with the increase in the labor mobility of men and their newly gained education is politically devalued when compared to the informal education that men gain through mobility, but on the other hand, schooling strengthens...

  11. Electric emissions from electrical appliances

    International Nuclear Information System (INIS)

    Leitgeb, N.; Cech, R.; Schroettner, J.

    2008-01-01

    Electric emissions from electric appliances are frequently considered negligible, and standards consider electric appliances to comply without testing. By investigating 122 household devices of 63 different categories, it could be shown that emitted electric field levels do not justify general disregard. Electric reference values can be exceeded up to 11-fold. By numerical dosimetry with homogeneous human models, induced intra-corporal electric current densities were determined and factors calculated to elevate reference levels to accounting for reduced induction efficiency of inhomogeneous fields. These factors were found not high enough to allow generally concluding on compliance with basic restrictions without testing. Electric appliances usually simultaneously emit both electric and magnetic fields exposing almost the same body region. Since the sum of induced current densities is limited, one field component reduces the available margin for the other. Therefore, superposition of electric current densities induced by either field would merit consideration. (authors)

  12. Electric crossover

    International Nuclear Information System (INIS)

    Schuster, R.M.; Luria, N.G.

    1977-01-01

    This invention concerns an electric crossover that makes a steam and pressure-tight seal for a conductor crossing two separate walls of a nuclear reactor vessel that seismic tremors or thermal expansion of the walls and conductor subject to relative displacements. The conductors, that have to cross the vessels, are fixed to the walls of the vessel in crossover systems fitted in crossover channels made in the walls of the vessel on their initial manufacture. The separate walls of the vessel move independently when they undergo an earth tremor or a temperature change between the walls or between the conductor. This shift can damage the conductor or the crossover system and this could give rise to cause steam or other materials to leak in the reactor should leaks occur in the primary system. Furthermore, in the case of medium or high power conductors, which are relatively rigid, the non-alignment of the crossover channels can bring about awkward stresses in the conductors or their protective sheathing. The aims of this invention are fulfilled by designing an electric crossover to pass at least one conductor through the two separate walls of a vessels, that includes an initial sub-assembly crossover, secured in a leak-tight manner to the first wall and a second sub-sessembly crossover in sliding or rolling contact with the second wall, whilst forming a leak-tight seal with it [fr

  6. Electric vehicles

    Science.gov (United States)

    1990-03-01

    Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. These concepts are discussed.

    Energy Technology Data Exchange (ETDEWEB)

    Reddoch, T.W.; Markel, L.C. [Electrotek Concepts, Inc., Knoxville, TN (United States)

    1991-12-31

    Investigations of the impact of high-altitude electromagnetic pulse (HEMP) on electric power systems and electrical equipment have revealed that HEMP creates both misoperation and failures. These events result from both the early time E{sub 1} (steep-front pulse) component and the late time E{sub 3} (geomagnetic perturbations) component of HEMP. In this report a HEMP event is viewed in terms of its marginal impact over classical power system disturbances by considering the unique properties and consequences of HEMP. This report focuses on system-wide electrical component failures and their potential consequences from HEMP. In particular, the effectiveness of planning and operating procedures for electric systems is evaluated while under the influence of HEMP. This assessment relies on published data and characterizes utilities using the North American Electric Reliability Council`s regions and guidelines to model electric power system planning and operations. Key issues addressed by the report include how electric power systems are affected by HEMP and what actions electric utilities can initiate to reduce the consequences of HEMP. The report also reviews the salient features of earlier HEMP studies and projects, examines technology trends in the electric power industry which are affected by HEMP, characterizes the vulnerability of power systems to HEMP, and explores the capability of electric systems to recover from a HEMP event.

    This article summarizes common principles, practices, and ethics of Native American healing, the traditional medicine of North America. Native American healing, spirituality, culture, and, in modern times, political, social, and economic concerns are closely intertwined. Intuition and spiritual awareness are a healer's most essential diagnostic tools. Therapeutic methods include prayer, music, ritual purification, herbalism, massage, ceremony, and personal innovations of individual healers. A community of friends, family, and helpers often participate in the healing intervention and help to alleviate the alienation caused by disease. A healthy patient has a healthy relationship with his or her community and, ultimately, with the greater community of nature known as "All Relations." The goal of Native American healing is to find wholeness, balance, harmony, beauty, and meaning. "Healing," making whole, is as important as curing disease; at times they are identical.

    The history of the electrical power sector in Mexico, the prominent role that government plays in the generation, transformation, distribution and supply of electrical power, and the implications of the North American Free Trade Agreement (NAFTA) for this sector were summarized. The slow pace of the Mexican electricity sector in achieving cost efficiency through pricing policy was criticized, and the issue of regulation versus deregulation of the electricity sector was examined in the context of NAFTA, emphasizing the contradiction between the idea of international trade and a highly regulated industry. Revisions of the original constitutional article to exclude electrical power generation from governmental control and to allow market mechanisms and competition to lower costs and increase efficiency was recommended.It was considered a pre-condition to a stable balance between competition and energy efficient environmentally friendly practices.

    Full Text Available The "Founding fathers" of American Studies at MGIMO are considered to be A.V. Efimov and L.I. Clove. Alexey Efimov - Corresponding Member of the USSR Academy of Sciences since 1938, Head of the Department of Modern and Contemporary History and Dean of the Historical School at the Moscow State University - one of the first professors of the Faculty of International Relations MGIMO. Efimov distinguished himself by a broad vision and scope of scientific interests. Back in 1934 he published a monograph "On the history of capitalism in the United States," which initiated a series of research culminating in the fundamental work "The United States. The path of capitalist development (pre-imperialist era". Alexey was not only a great scientist but also a great teacher, whose lectures was popular throughout Moscow. His lecture courses, given at the end of the 1940s at MGIMO, became the basis for the first post-war history textbooks USA - "Essays on the history of the United States." At least as colorful a figure was Professor Leo Izrailevich Zubok - a man of unusual destiny. As a teenager he emigrated to the United States with his parents, where he soon joined the American revolutionary movement in the 1920s and was forced to leave the country. He came to MGIMO being already an experienced scientists. His research interests were very wide: from the study of American foreign policy expansion to the history of the labor movement in the United States. Zubok's fundamental works still have not lost its scientific significance. He has successfully combined scientific work with teaching. Tutorials that are based on his lectures were very popular not only among students of MGIMO.

    Electricity trade across regions is often considered welfare enhancing. We show in this paper that this should be reconsidered if environmental externalities are taken into account. We consider two cases where trade is beneficial, before accounting for environmental damages: first, when two regions with the same technology display some demand heterogeneity; second when one region endowed with hydropower arbitrages with its 'thermal' neighbor. Our results show that under reasonable demand and supply elasticities, trade comes with an additional environmental cost. This calls for integrating environmental externalities into market reforms when redesigning the electricity sector. Two North American applications illustrate our results: trade between Pennsylvania and New York, and trade between hydro-rich Quebec and New York.

    2002-07-01

    The Ontario Electricity Act and the Market Rules oblige electricity market participants to prepare and submit emergency plans to ensure the safe and reliable operation of the power system. Security and emergency preparedness includes emergency planning, drills and exercises, and critical infrastructure protection. The risk of power disruption is credible and the impact is large, as witnessed by the 1998 ice storm in eastern Ontario which resulted in major power outages, and as witnessed by the events of September 11, 2001. The emergency control actions that manage power system contingencies include recalling planned outages, reducing interchanges, increasing reserves, reducing voltage, purchasing emergency energy, and load shedding. Restoration priorities are to first restore power to critical transmission and generating station service loads, then to restore critical telecom facilities. This is followed by the restoration of customer loads only to the extent needed to control voltage and secure generating units. The final priority is to interconnect neighbours. The North American Electric Reliability Council (NERC) was established following the major 1965 blackout. NERC developed operational reliability standards and monitored compliance. A map depicting NERC regions and control areas in the US was presented. In Canada, the Canadian Electricity Association (CEA) addresses issues regarding critical infrastructure protection (CIP). It safeguards the essential components of the electricity infrastructure against physical and cyber threats through early warning systems and information sharing. 9 figs.

  17. Heat Pump Water Heaters and American Homes: A Good Fit?

    Energy Technology Data Exchange (ETDEWEB)

    2010-05-14

    Heat pump water heaters (HPWHs) are over twice as energy-efficient as conventional electric resistance water heaters, with the potential to save substantial amounts of electricity. Drawing on analysis conducted for the U.S. Department of Energy's recently-concluded rulemaking on amended standards for water heaters, this paper evaluates key issues that will determine how well, and to what extent, this technology will fit in American homes. The key issues include: 1) equipment cost of HPWHs; 2) cooling of the indoor environment by HPWHs; 3) size and air flow requirements of HPWHs; 4) performance of HPWH under different climate conditions and varying hot water use patterns; and 5) operating cost savings under different electricity prices and hot water use. The paper presents the results of a life-cycle cost analysis of the adoption of HPWHs in a representative sample of American homes, as well as national impact analysis for different market share scenarios. Assuming equipment costs that would result from high production volume, the results show that HPWHs can be cost effective in all regions for most single family homes, especially when the water heater is not installed in a conditioned space. HPWHs are not cost effective for most manufactured home and multi-family installations, due to lower average hot water use and the water heater in the majority of cases being installed in conditioned space, where cooling of the indoor environment and size and air flow requirements of HPWHs increase installation costs.

  20. Electricity from biogas

    International Nuclear Information System (INIS)

    Augenstein, D.; Benemann, J.; Hughes, E.

    1994-01-01

    Biogas is a medium-Btu methane and carbon dioxide mix produced by bacterial decomposition of organic matter. Its sources include landfills, waste water sludges, and animal wastes. It can fuel energy applications, of which electricity generation is a frequently-preferred option. The greatest current U.S. biogas recovery and energy use is at landfills, where biogas at about 80 landfill sites fuels a total of approximately 300 MWe. Wastewater treatment plants and confined animal waste management systems support additional electric power production. Generation of electricity from biogas can present difficulties due to the generally small scale of the generating facility, variable energy content of the gas, fluctuating availability, contaminant problems, and often-demanding control needs. However, such difficulties are being successfully addressed and economics for electricity generation are often favorable as biogas can be essentially open-quotes freeclose quotes fuel. Biogas recovery and use has the additional advantage of mitigating a potent greenhouse gas. Biogas from U.S. landfills alone could fuel about 1% of U.S. electrical generation while giving climate change benefit equivalent to reducing CO 2 emissions in the electricity sector by more than 10%. Growth in landfill gas use will be facilitated by recent regulations, advances in equipment, and improved management techniques such as open-quotes controlled landfillingclose quotes. The potential for biogas recovery and electricity production from sewage sludges, animal wastes and other organic resources such as agricultural residues is uncertain but probably exceeds the estimate for landfills

    2000-01-01

    The Federal Energy Management Program (FEMP) in the U.S. Department of Energy (DOE) is targeting Federal facilities serving Native American populations for cost-effective renewable energy projects. These projects not only save energy and money, they also provide economic opportunities for the Native Americans who assist in producing, installing, operating, or maintaining the renewable energy systems obtained for the facilities. The systems include solar heating, solar electric (photovoltaic or PV), wind, biomass, and geothermal energy systems. In fiscal years 1998 and 1999, FEMP co-funded seven such projects, working with the Indian Health Service in the U.S. Department of Health and Human Services, the Bureau of Indian Affairs in the U.S. Department of the Interior, and their project partners. The new renewable energy systems are helping to save money that would otherwise be spent on conventional energy and reduce the greenhouse gases associated with burning fossil fuels

    2010-01-12

    To determine if transcutaneous electric nerve stimulation (TENS) is efficacious in the treatment of pain in neurologic disorders. We performed a systematic literature search of Medline and the Cochrane Library from inception to April 2009. There are conflicting reports of TENS compared to sham TENS in the treatment of chronic low back pain, with 2 Class II studies showing benefit, but 2 Class I studies and another Class II study not showing benefit. Because the Class I studies are stronger evidence, TENS is established as ineffective for the treatment of chronic low back pain (2 Class I studies). TENS is probably effective in treating painful diabetic neuropathy (2 Class II studies). Transcutaneous electric nerve stimulation (TENS) is not recommended for the treatment of chronic low back pain (Level A). TENS should be considered in the treatment of painful diabetic neuropathy (Level B). Further research into the mechanism of action of TENS is needed, as well as more rigorous studies for determination of efficacy.

    2002-01-01

    The purpose of the 'Electricity market 2002' publication is to meet the need for generalized and readily accessible information on the conditions on the Nordic market. Iceland is not included in the description. The publication also includes summaries of information from recent years concerning electricity generation and utilization in the Nordic countries, the structure of the electricity market from the players' perspective, trade in electricity in the Nordic countries and in Northern Europe, electricity prices in the Nordic and other countries, and the impact of the electricity sector on the environment. The publication contains data on electricity generation and use during the past years, structure of the electricity market, trade in electricity in the Nordic countries and northern Europe, electricity prices in the Nordic countries and other countries as well as impact of electricity generation system on the environment. The market price of electricity is affected by a number of factors, including fuel prices, availability of water, and the power and energy balances of the various countries. The availability of water in Norway and Sweden has been very good in recent years, which has had a major influence on the price. 1996 was a dry year, which led to a high system price on Nord Pool. The price of electricity then dropped and has remained at a relatively low level up to the year 2001. The price of electricity rose during the spring of 2001 and remained at a higher level also during the summer months. The main reason was that the availability of water was lower than normal in Norway during the early part of the year. This created a higher demand for imported electricity in Norway and caused some apprehension that the year would be dry. The total price of electricity to the end users has not followed the system price development. The total cost of electricity to the end consumers consists of three items, i.e. the price of electricity, the network charges and

    Full Text Available A major problem facing battery-powered electric vehicles is in their batteries: weight and charge capacity. Thus, a battery-powered electric vehicle only has a short driving range. To travel for a longer distance, the batteries are required to be recharged frequently. In this paper, we construct a model for a battery-powered electric vehicle, in which driving strategy is to be obtained such that the total travelling time between two locations is minimized. The problem is formulated as an optimization problem with switching times and speed as decision variables. This is an unconventional optimization problem. However, by using the control parametrization enhancing technique (CPET, it is shown that this unconventional optimization is equivalent to a conventional optimal parameter selection problem. Numerical examples are solved using the proposed method.

    The Central American regional interconnected power system (SER) connects the countries members of the Central American regional electricity market (MER): Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama. The SER was a result of a long term regional effort, and was initially conceived to transfer 300 MW between countries. However, the current transfer limits between countries range from 70 MW to 300 MW. Regional entities, like CRIE (Regional Commission of Electrical Interconnection), EOR (Central American Regional System Operator), and CDMER (Board of Directors of the Central American Market) are working on coordinating the national transmission expansion plans with regional transmission planning efforts. This paper presents experience in Central America region to recommend transmission reinforcements to achieve 300 MW transfer capacity between any pair of member countries of the Central American regional electricity market (MER). This paper also provides a methodology for technical analysis and for coordination among the regional and national entities. This methodology is unique for transmission systems of these characteristics.

    2018-02-01

    Electricity occurs in atmospheres across the Solar System planets and beyond, spanning spectacular lightning displays in clouds of water or dust, to more subtle effects of charge and electric fields. On Earth, lightning is likely to have existed for a long time, based on evidence from fossilized lightning strikes in ancient rocks, but observations of planetary lightning are necessarily much more recent. The generation and observations of lightning and other atmospheric electrical processes, both from within-atmosphere measurements, and spacecraft remote sensing, can be readily studied using a comparative planetology approach, with Earth as a model. All atmospheres contain charged molecules, electrons, and/or molecular clusters created by ionization from cosmic rays and other processes, which may affect an atmosphere's energy balance both through aerosol and cloud formation, and direct absorption of radiation. Several planets are anticipated to host a "global electric circuit" by analogy with the circuit occurring on Earth, where thunderstorms drive current of ions or electrons through weakly conductive parts of the atmosphere. This current flow may further modulate an atmosphere's radiative properties through cloud and aerosol effects. Lightning could potentially have implications for life through its effects on atmospheric chemistry and particle transport. It has been observed on many of the Solar System planets (Earth, Jupiter, Saturn, Uranus, and Neptune) and it may also be present on Venus and Mars. On Earth, Jupiter, and Saturn, lightning is thought to be generated in deep water and ice clouds, but discharges can be generated in dust, as for terrestrial volcanic lightning, and on Mars. Other, less well-understood mechanisms causing discharges in non-water clouds also seem likely. The discovery of thousands of exoplanets has recently led to a range of further exotic possibilities for atmospheric electricity, though lightning detection beyond our Solar System

    The judge was driving back late one cold winter night. Entering the garage, the battery-charging indicator in his wirelessly powered electric car came on. "Home at last," crossed his mind. He swiped his personal smartcard on the front-door detector to be let in. He heard a "charging" beep from his mobile phone. The blinking cursor on the half-finished e-mail on the laptop had been waiting all day on the side table. He picked the computer up and walked towards his desk. "Good evening, your honour. Your wirelessly heated robe," said the butler-robot as it approached from the kitchen. Putting on the electric garment, he sat on the medical desk chair. His artificial heart was now beating faster.

    1994-01-01

    Electricity demand forecasting plays an important role in power generation. The two areas of data that have to be forecasted in a power system are peak demand which determines the capacity (MW) of the plant required and annual energy demand (GWH). Methods used in electricity demand forecasting include time trend analysis and econometric methods. In forecasting, identification of manpower demand, identification of key planning factors, decision on planning horizon, differentiation between prediction and projection (i.e. development of different scenarios) and choosing from different forecasting techniques are important

  17. Electrical deregulation

    International Nuclear Information System (INIS)

    Simpson, R.

    2001-01-01

    Deregulation in the electricity sector took effect on January 1, 2001 in Alberta. Business consumers discovered that their electricity rates had almost doubled in a one-month period. The government argued that it was the case of short term pain for long term gain. The intent of the deregulation is the lowering of prices through competition. This principle applies when the supply meets the demand, but when the demand exceeds the supply, prices increase. When initial plans were made for the deregulation of the sector, utilities did not invest huge amounts of capital to build new generation plants, as it was not known how they would fare in the deregulated environment. This situation was compounded by the fact that there was an economic boom around the same time in Alberta, adding to the demands made on the existing generation infrastructure (approximately 4 per cent per year over the past decade). At the moment, some resource developers such as Syncrude, Amoco, and Daishowa produce their own electricity and export their excess capacity to the provincial grid for general use. The rules of the deregulated market have been clarified and a number of utilities are planning new generation plants and facilities. TransAlta, EPCOR, and Enmax Corp. have announced plans to expand or build new coal-fired plants. Alberta has an estimated 35 billion tonnes of recoverable coal, and 25 million tonnes of coal were used in 1999 to produce 75 per cent of the electricity required in Alberta. Over the next ten years, 4,000 megawatts of new capacity is planned, representing a 50 per cent increase over current levels. AES Corporation, a Virginia power giant, has also announced plans to build a generator in Alberta

    1997-01-01

    Hybrid electric power trains may revolutionize today's ground passenger vehicles by significantly improving fuel economy and decreasing emissions. The NASA Lewis Research Center is working with industry, universities, and Government to develop and demonstrate a hybrid electric vehicle. Our partners include Bowling Green State University, the Cleveland Regional Transit Authority, Lincoln Electric Motor Division, the State of Ohio's Department of Development, and Teledyne Ryan Aeronautical. The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

    2003-01-01

    Findings of an independent review of charges to electricity bills and recommendations to assist in the development of a standard, province-wide residential electricity bill for Ontario are discussed. The review was requested by the province's Minister of Energy in an effort to dispel growing confusion about the variations in customer billing practices used by the province's 90+ local distribution companies. Key recommendations and findings were as follows: (1)Consumer bill formats issued by local distribution companies should be more consumer-friendly, adhere to minimum design standards, adapt uniform terminology and common line charges; (2) charges on customer bills should be grouped into four standard line items, with full details available to customers: the four line items should be a basic service charge, a charge for delivering electricity to the customer, a charge for the electricity itself, and a separate charge for retiring the outstanding debt of the former Ontario Hydro; (3) bills should take advantage of opportunities for promoting province-wide energy conservation, such as encouraging the long-term use of interval meters, presenting historical consumption data on residential bills on a period-to-period basis, and education and communications initiatives. Details of the recommendations, including the calculation of the fixed and variable components of usage charges, an explanation of the concept of electricity system loss adjustments, a method for phasing in the recommendations, and the anticipated benefits to consumers are provided

    2004-01-01

    This paper provides an update of electricity issues concerning Nova Scotia such as supply, capacity, emission commitments, as well as co-generation and the Electricity Marketplace Governance Committee (EMGC). The goals of the strategy were reliability combined with competitive prices and greater environmental responsibility. The scope of these objectives included new capacity, transmission, renewables and co-generation. Other objectives included encouraging wholesale market competition; meeting reciprocity requirements; and a 50 MW renewable energy target. Recommendations of the EMGC included wholesale market competition; a broader market scope with a cost benefit analysis; Open Access Transmission Tariff (OATT); a scheduling and information system; network integration and a point to point service; and a separation of transmission and generation business units. Other recommendations included an open competitive process for new generation; a consideration of emissions and overall efficiency; a Renewable Energy Portfolio Standard (RPS) to start in 2006; the separation of RPS tags from electricity; and net metering of renewables. These recommendations were accepted in 2003, followed by the new Electricity Act in 2004, which made OATT mandatory, established RPS and opened to the wholesale market. Capacity at present was considered to be tight, with preparations for the new regulations under way. Reductions in air pollution were reported at 25 per cent, with renewable energy projects such as 2 windmills currently under way, as well as various other projects. Opportunities for provincial Atlantic cooperation were identified as being management of reserve requirements; trading of lowest cost electricity; new generation on a regional scale; stronger transmission ties; a system operator; a regional approach to RPS; regional management of air emissions; and regional opportunities for Carbon dioxide reductions. tabs., figs

  4. Static electricity: A literature review

    Science.gov (United States)

    Crow, Rita M.

    1991-11-01

    The major concern with static electricity is its discharging in a flammable atmosphere which can explode and cause a fire. Textile materials can have their electrical resistivity decreased by the addition of antistatic finishes, imbedding conductive particles into the fibres or by adding metal fibers to the yarns. The test methods used in the studies of static electricity include measuring the static properties of materials, of clothed persons, and of the ignition energy of flammable gases. Surveys have shown that there is sparse evidence for fires definitively being caused by static electricity. However, the 'worst-case' philosophy has been adopted and a static electricity safety code is described, including correct grounding procedures and the wearing of anti-static clothing and footwear.

    Karp, J K

    2014-02-01

    Television is a beloved American pastime and a frequent American export. As such, American television shapes how the global public views the world. This study examines how the portrayal of blood transfusion and blood donation on American television may influence how domestic and international audiences perceive the field of transfusion medicine. American television programming of the last quarter-century was reviewed to identify programmes featuring topics related to blood banking/transfusion medicine. The included television episodes were identified through various sources. Twenty-seven television episodes airing between 1991 and 2013 were identified as featuring blood bank/transfusion medicine topics. Although some accurate representations of the field were identified, most television programmes portrayed blood banking/transfusion medicine inaccurately. The way in which blood banking/transfusion medicine is portrayed on American television may assist clinicians in understanding their patient's concerns about blood safety and guide blood collection organisations in improving donor recruitment. © 2013 The Author.

    Electrical storm is defined as repeated occurrence of severe ventricular arrhythmias requiring multiple cardioversions, two or more or three or more following different studies. The clinical aspect can sometimes be made of multiple, self aggravating, life threatening accesses. There are three main clinical circumstances of occurrence: in patients equipped with intracardiac defibrillators, during the acute phase of myocardial infarction and in Brugada syndrome. 10 to 15% of patients with cardiac defibrillators are subject to electrical storms in a period of two years. The causative arrhythmia is most often ventricular tachycardia than ventricular fibrillation, especially in secondary prevention and if the initial arrhythmias justifying the device was a ventricular tachycardia. Precipitaing factors are present in one third of cases, mainly acute heart failure, ionic disorders and arrhythmogenic drugs. Predictive factors are age, left ventricular ejection fractionelectrical shock in 50% of cases, antitachycardi stimulation in 30% and in 20% by association of the two. Treatment, after elimination of inappropriate shocks, is mainly based on beta-blockers and amiodarone, class I antiarrhythmics, lidocaïne or bretylium in some cases, and sedation pushed to general anesthesia in some cases. Radio-frequency ablation and even heart transplantation have been proposed in extreme cases. Quinidine has been proved efficient in cases of Brugada syndrome.

    To properly take climate change into account in the analysis of energy investment decisions, it is required to apply decision analysis methods that are capable of considering the specific characteristics of climate change (large uncertainties, long term horizon). Such decision analysis methods do exist. They can explicitly include evolving uncertainties, multi-stage decisions, cumulative effects and risk averse attitudes. Various methods are considered in this report and two of these methods have been selected: hedging calculations and sensitivity analysis. These methods are applied to illustrative examples, and its limitations are discussed. The examples are (1a) space heating and hot water for new houses from a private investor perspective and (1b) as example (1a) but from a government perspective, (2) electricity production with an integrated coal gasification combined cycle (ICGCC) with or without CO 2 removal, and (3) national energy strategy to hedge for climate change. 9 figs., 21 tabs., 42 refs., 1 appendix

  13. Electrically Conductive Anodized Aluminum Surfaces

    Science.gov (United States)

    Nguyen, Trung Hung

    2006-01-01

    Anodized aluminum components can be treated to make them sufficiently electrically conductive to suppress discharges of static electricity. The treatment was conceived as a means of preventing static electric discharges on exterior satin-anodized aluminum (SAA) surfaces of spacecraft without adversely affecting the thermal-control/optical properties of the SAA and without need to apply electrically conductive paints, which eventually peel off in the harsh environment of outer space. The treatment can also be used to impart electrical conductivity to anodized housings of computers, medical electronic instruments, telephoneexchange equipment, and other terrestrial electronic equipment vulnerable to electrostatic discharge. The electrical resistivity of a typical anodized aluminum surface layer lies between 10(exp 11) and 10(exp 13) Omega-cm. To suppress electrostatic discharge, it is necessary to reduce the electrical resistivity significantly - preferably to anodized surface becomes covered and the pores in the surface filled with a transparent, electrically conductive metal oxide nanocomposite. Filling the pores with the nanocomposite reduces the transverse electrical resistivity and, in the original intended outer-space application, the exterior covering portion of the nanocomposite would afford the requisite electrical contact with the outer-space plasma. The electrical resistivity of the nanocomposite can be tailored to a value between 10(exp 7) and 10(exp 12) Omega-cm. Unlike electrically conductive paint, the nanocomposite becomes an integral part of the anodized aluminum substrate, without need for adhesive bonding material and without risk of subsequent peeling. The electrodeposition process is compatible with commercial anodizing production lines. At present, the electronics industry uses expensive, exotic, electrostaticdischarge- suppressing finishes: examples include silver impregnated anodized, black electroless nickel, black chrome, and black copper.

  14. Modelling electric discharge chemistry

    1991-07-01

    The chemistry occurring in a electric discharge was modelled to predict how it would be influenced by discharge conditions. The discharge was characterized by a calculated Boltzmann electron-energy distribution, from which rate constants for electron-molecule processes in air were determined. These rate constants were used in a chemical kinetics calculation that also included reactions between neutral molecules, ions, free radicals and electronically excited species. The model describes how the discharge chemistry was influenced by humidity, electric field, electron number density, and concentrations of key reagents identified in the study. The use of an electric discharge to destroy airborne contaminant molecules was appraised, the targeted contaminants being CF 2 Cl 2 , HCN, and SO 2 . The modelling results indicate that an electric discharge should be able to remove HCN and CF 2 Cl 2 effectively, especially if the discharge conditions have been optimized. Effective destruction is achieved with a moderate electric field (over 1 x 10 -15 V.cm 2 ), a substantial electron number density (over 1 x 10 12 cm -3 ), and the presence of H 2 0 in the process air. The residence time in the discharge was also shown to be important in contaminant destruction. An attempt was made to explain the results of the electric discharge abatement of SO 2 , a component of a simulated flue-gas mixture. Results from the model indicate that the discharge parameters that increase the concentration of hydroxyl radical also increase the rate of decomposition of SO 2 . An objective of the study was to explain the apparent enhancement of SO 2 destruction by the presence of a small amount of NO 2 . It was thought that a likely explanation would be the stabilization of HOSO 2 , an important intermediate in the oxidation of SO 2 by NO 2 . (49 figs., 14 tabs., 75 refs.)

    1993-06-01

    Electricity exports from Hydro-Quebec to utilities in the USA significantly affects the economy and environment of Quebec. These exports may be arranged under interconnection agreements to sell excess capacity and production during off-peak periods or under firm sales contracts. Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

    Falthammar, C.G.

    1989-01-01

    Electric field measurements on the satellites GEOS-1, GEOS-2, ISEE-1, and Viking have extended the empirical knowledge of electric fields in space so as to include the outer regions of the magnetosphere. While the measurements confirm some of the theoretically expected properties of the electric fields, they also reveal unexpected features and a high degree of complexity and variability. The existence of a magnetospheric dawn-to-dusk electric field, as expected on the basis of extrapolation from low altitude measurements, is confirmed in an average sense. However, the actual field exhibits large spatial and temporal variations, including strong fields of inductive origin. At the magnetopause, the average (dawn-to-dusk directed) tangential electric field component is typically obscured by irregular fluctuations of larger amplitude. The magnetic-field aligned component of the electric field, which is of particular importance for ionosphere-magnetosphere coupling and for auroral acceleration, is even now very difficult to measure directly. However, the data from electric field measurements provide further support for the conclusion, based on a variety of evidence, that a non-vanishing magnetic-field aligned electric field exists in the auroral acceleration region

  20. The electricity certificate system, 2007

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    The electricity certificate system is a market based support system to assist the expansion of electricity production in Sweden from renewable energy sources and peat. Its objective is to increase the production of electricity from such sources by 17 TWh by 2016 relative to the production level in 2002. It is part of the country's overall objective of moving Sweden towards a more ecologically sustainable energy system. This report describes the market status of the electricity certificate system, and includes statistics from 2003 to 2006. It is our aim to create a forum for continuously developing the statistical material and analyses, in order to assist those involved in the market, and all other interested persons, to follow achievement of the objectives set out in the Government's Bill No. 2005/06:154, Renewable Electricity with Green Certificates. It is also our aim that, in future, each issue of the report should include a more in depth theme article on some particular subject. This year the report provides expanded information and statistics on wind power. Electricity certificates are issued to those who produce electricity from various renewable energy sources, and from peat, and who have had their production plants approved by the Swedish Energy Agency. To date, certificates have been issued to producers of electricity from biofuels and peat, wind power, hydro power and solar energy. Production from the renewable sources amounted to 11.6 TWh in 2006, which is 5.1 TWh more than corresponding production in 2002

    Mental illness stigma is prevalent among Asian Americans, and it is a key barrier that prevents them from seeking psychological services. Limited studies have experimentally examined how Asian Americans respond to biological and social explanations of mental illness. Understanding how to educate and communicate about mental illness effectively is crucial in increasing service utilization among Asian Americans. To assess how genetic, neurobiological, and social explanations for the onset of depression affects Asian American and European American's mental illness stigma. 231 Asian Americans and 206 European Americans read about an individual with major depression and were randomly assigned to be informed that the cause was either genetic, neurobiological, social, or unknown. Various stigma outcomes, including social distance, fear, and depression duration were assessed. Consistent with prior research, Asian Americans had higher baseline levels of stigma compared to European Americans. Greater social essentialist beliefs predicted positive stigma outcomes for Asian Americans, such as a greater willingness to be near, help, and hire someone with depression, but genetic essentialist beliefs predicted negative stigma outcomes, such as fear. In addition, a social explanation for the etiology of depression led to lower stigma outcomes for Asian Americans; it decreased their fear of someone with depression and increased the perception that depression is treatable. For European Americans, both genetic and social essentialist beliefs predicted a greater perception of depression treatability. Although genetics do play a role in the development of depression, emphasizing a social explanation for the origin of depression may help reduce stigma for Asian Americans.

  3. The effect of economic factors and energy efficiency programs on residential electricity consumption

    Science.gov (United States)

    Sakai, Mihoko

    Many countries have implemented policies to correct market and behavioral failures that lead to inefficient energy use. It is important to know what factors and policies can effectively overcome such failures and improve energy efficiency; however, a comprehensive analysis has been difficult because of data limitations. Using state scores compiled by American organizations recently, and adopting fixed-effects regression models, I analyze the joint impacts of relevant factors and policy programs on residential electricity consumption in each U.S. state. The empirical results reveal that increases in electricity price have small and negative effects, and increases in personal income have positive effects on residential electricity sales per capita (a measure of energy efficiency). The results suggest that it may take time for economic factors to affect electricity sales. The effects of personal income suggest the difficulty of controlling residential electricity consumption; however, they also imply that there is some room in households to reduce electricity use. The study also finds that programs and budgets of several policies seem to be associated with electricity sales. The estimates from a model including interaction terms suggest the importance of including multiple policies when analyzing and designing policies to address electricity efficiency. The results also imply the possibility of rebound effects of some policies, whereby improvements in energy efficiency lead to increases in energy consumption due to the associated lower per unit cost. Future studies should analyze both short-term and long-term effects of economic factors and policies, based on improved and accumulated time series and panel data, in order to design more effective policies for improving residential electricity efficiency.

    There is a large number of different configurations for the combination of a closed cycle gas turbine (CCGT) system and a high-temperature gas-cooled reactor (HTGR). Based on the results of a literature survey an overview of such configurations is presented and a comparison is made for their appropriateness for a small cogeneration system (<60 MWt) to be used in the Netherlands. However, most cycles can only be applied for large-scale energy production or supply heat on a too low temperature level. The direct, recuperated cycle is the only suitable cycle, while that cycle is a simple system and shows an acceptable electric and total efficiency. Calculations were carried out for the co-production of hot water (75-125C and 40-70C) and for steam (10 bar, 220C). By means of a static model and an optimizer the feasible efficiencies for different heat demand are determined. The maximum electric efficiency is 42% for the co-production of hot water and 38% for the co-production of steam. 28 refs.

We show that, if we regard a matrix element defined in terms of the future state at time T and the past state at time TA as an expectation value in the CAT, then we are allowed to have the Heisenberg equation......, Ehrenfest's theorem, and the conserved probability current density. In addition,we showthat the expectation value at the present time t of a future-included theory for large T - t and large t - T corresponds to that of a future-not-included theory with a proper inner product for large t - T.

    1990-01-01

    In this amendment debate about the privatisation of the electricity supply, the opposition develops a number of themes detracting from the government's policy in this matter. It is felt that the industry is being sold off much too cheaply, at about one third of its value based on previous audits. Measures to prevent environmental damage are not likely to be implemented as they would reduce profits. Fuel reserves are in danger of depletion, especially natural gas. Coal imports will increase with accompanying threats to the balance of payments. Lastly, it is argued that very large sums of money are being paid unnecessarily to City Analysts and that big business and M.P.s are acting immorally in extracting money from what should be a publicly owned utility. The amendment was defeated by 298 to 186. (author)

    A government, industry, and university cooperative is developing an advanced hybrid electric city transit bus. Goals of this effort include doubling the fuel economy compared to current buses and reducing emissions to one-tenth of current EPA standards. Unique aspects of the vehicle's power system include the use of ultra-capacitors as an energy storage system, and a planned natural gas fueled turbogenerator developed from a small jet engine. Power from both the generator and energy storage system is provided to a variable speed electric motor attached to the rear axle. At over 15000 kg gross weight, this is the largest vehicle of its kind ever built using ultra-capacitor energy storage. This paper describes the overall power system architecture, the evolution of the control strategy, and its performance over industry standard drive cycles.

  6. Privatization of municipal electrical utilities

    International Nuclear Information System (INIS)

    Carr, J.

    1998-01-01

    The challenges and special issues which arise through the sale of a municipal electric utility were discussed. The recent sales of two utilities, the Kentville Electric Commission in Nova Scotia and Cornwall Electric in Ontario, were used as examples to show how the sale of an electric utility differs from the sale of most business enterprises. Municipal utilities are integral parts of the communities they serve which introduces several complexities into the sale. Factors that require special attention in the sale of the utilities, including electricity rates, local accountability, treatment of employees and local economic development, and the need for a comprehensive communication program to deal with the substantial public interest that sale of a municipal utility will engender, were reviewed

    1986-01-01

    This study is about future needs for electricity in the United Kingdom, the options for meeting these needs, and the issues that affect the choices between options. It examines the implications of the nuclear accident at Chernobyl and the problems that could arise if decisions on new power station construction continue to be delayed following the Sizewell PWR Inquiry. The book reviews the historical development of electricity supply in the UK. Alternative scenarios are outlined for future energy and electricity demand and their implications for future power station construction are deduced. Issues that are discussed include the choice of coal or nuclear power and the related political uncertainties, environmental problems such as acid rain, feasibility and costs of electricity supply options, and the likely effect on future energy import costs of alternative choices for electricity supply.

  10. Electric organ discharges and electric images during electrolocation

    Science.gov (United States)

    Assad, C.; Rasnow, B.; Stoddard, P. K.

    1999-01-01

    Weakly electric fish use active electrolocation - the generation and detection of electric currents - to explore their surroundings. Although electrosensory systems include some of the most extensively understood circuits in the vertebrate central nervous system, relatively little is known quantitatively about how fish electrolocate objects. We believe a prerequisite to understanding electrolocation and its underlying neural substrates is to quantify and visualize the peripheral electrosensory information measured by the electroreceptors. We have therefore focused on reconstructing both the electric organ discharges (EODs) and the electric images resulting from nearby objects and the fish's exploratory behaviors. Here, we review results from a combination of techniques, including field measurements, numerical and semi-analytical simulations, and video imaging of behaviors. EOD maps are presented and interpreted for six gymnotiform species. They reveal diverse electric field patterns that have significant implications for both the electrosensory and electromotor systems. Our simulations generated predictions of the electric images from nearby objects as well as sequences of electric images during exploratory behaviors. These methods are leading to the identification of image features and computational algorithms that could reliably encode electrosensory information and may help guide electrophysiological experiments exploring the neural basis of electrolocation.

  11. Neoclassical transport including collisional nonlinearity.

    Science.gov (United States)

    Candy, J; Belli, E A

    2011-06-10

    In the standard δf theory of neoclassical transport, the zeroth-order (Maxwellian) solution is obtained analytically via the solution of a nonlinear equation. The first-order correction δf is subsequently computed as the solution of a linear, inhomogeneous equation that includes the linearized Fokker-Planck collision operator. This equation admits analytic solutions only in extreme asymptotic limits (banana, plateau, Pfirsch-Schlüter), and so must be solved numerically for realistic plasma parameters. Recently, numerical codes have appeared which attempt to compute the total distribution f more accurately than in the standard ordering by retaining some nonlinear terms related to finite-orbit width, while simultaneously reusing some form of the linearized collision operator. In this work we show that higher-order corrections to the distribution function may be unphysical if collisional nonlinearities are ignored.

    International Nuclear Information System (INIS)

    Freeman, W.E.

    1992-01-01

    This paper adds thermal properties to previously developed electrical Saber templates and incorporates these templates into a functional Electrical Power Subsystem (EPS) simulation. These combined electrical and thermal templates enable the complete and realistic simulation of a vehicle EPS on-orbit. Applications include on-orbit energy balance determinations for system load changes, initial array and battery EPS sizing for new EPS development, and array and battery technology trade studies. This effort proves the versatility of the Saber simulation program in handling varied and complex simulations accurately and in a reasonable amount of computer time. 9 refs

    Surface electrical geophysical methods have been used in such engineering applications as locating and delineating shallow gravel deposits, depth to bedrock, faults, clay zones, and other geological phenomena. Other engineering applications include determining water quality, tracing ground water contaminant plumes and locating dam seepages. Various methods and electrode arrays are employed to solve particular geological problems. The sensitivity of a particular method or electrode array depends upon the physics on which the method is based, the array geometry, the electrical contrast between the target and host materials, and the depth to the target. Each of the available electrical methods has its own particular advantages and applications which the paper discusses.

    The conversion of heat energy into electrical energy by a small compact device is descrtbed. Where the heat energy is supplied by a radioactive material and thermopIIes convert the heat to electrical energy. The particular battery construction includes two insulating discs with conductive rods disposed between them to form a circular cage. In the center of the cage is disposed a cup in which the sealed radioactive source is located. Each thermopile is formed by connecting wires from two adjacent rods to a potnt on an annular ring fastened to the outside of the cup, the ring having insulation on its surface to prevent electrica1 contact with the thermopiles. One advantage of this battery construction is that the radioactive source may be inserted after the device is fabricated, reducing the radiation hazard to personnel assembling the battery.

    Electrical power system options for Mars Manned Modules and Mars Surface Bases were evaluated for both near-term and advanced performance potential. The power system options investigated for the Mission Modules include photovoltaics, solar thermal, nuclear reactor, and isotope power systems. Options discussed for Mars Bases include the above options with the addition of a brief discussion of open loop energy conversion of Mars resources, including utilization of wind, subsurface thermal gradients, and super oxides. Electrical power requirements for Mission Modules were estimated for three basic approaches: as a function of crew size; as a function of electric propulsion; and as a function of transmission of power from an orbiter to the surface of Mars via laser or radio frequency. Mars Base power requirements were assumed to be determined by production facilities that make resources available for follow-on missions leading to the establishment of a permanently manned Base. Requirements include the production of buffer gas and propellant production plants.

  1. Essays on pricing electricity and electricity derivatives in deregulated markets

    Science.gov (United States)

    Popova, Julia

    2008-10-01

    This dissertation is composed of four essays on the behavior of wholesale electricity prices and their derivatives. The first essay provides an empirical model that takes into account the spatial features of a transmission network on the electricity market. The spatial structure of the transmission grid plays a key role in determining electricity prices, but it has not been incorporated into previous empirical models. The econometric model in this essay incorporates a simple representation of the transmission system into a spatial panel data model of electricity prices, and also accounts for the effect of dynamic transmission system constraints on electricity market integration. Empirical results using PJM data confirm the existence of spatial patterns in electricity prices and show that spatial correlation diminishes as transmission lines become more congested. The second essay develops and empirically tests a model of the influence of natural gas storage inventories on the electricity forward premium. I link a model of the effect of gas storage constraints on the higher moments of the distribution of electricity prices to a model of the effect of those moments on the forward premium. Empirical results using PJM data support the model's predictions that gas storage inventories sharply reduce the electricity forward premium when demand for electricity is high and space-heating demand for gas is low. The third essay examines the efficiency of PJM electricity markets. A market is efficient if prices reflect all relevant information, so that prices follow a random walk. The hypothesis of random walk is examined using empirical tests, including the Portmanteau, Augmented Dickey-Fuller, KPSS, and multiple variance ratio tests. The results are mixed though evidence of some level of market efficiency is found. The last essay investigates the possibility that previous researchers have drawn spurious conclusions based on classical unit root tests incorrectly applied to

    Population-wide reductions in cardiovascular disease incidence and mortality have not been shared equally by African Americans. The burden of cardiovascular disease in the African American community remains high and is a primary cause of disparities in life expectancy between African Americans and whites. The objectives of the present scientific statement are to describe cardiovascular health in African Americans and to highlight unique considerations for disease prevention and management. The primary sources of information were identified with PubMed/Medline and online sources from the Centers for Disease Control and Prevention. The higher prevalence of traditional cardiovascular risk factors (eg, hypertension, diabetes mellitus, obesity, and atherosclerotic cardiovascular risk) underlies the relatively earlier age of onset of cardiovascular diseases among African Americans. Hypertension in particular is highly prevalent among African Americans and contributes directly to the notable disparities in stroke, heart failure, and peripheral artery disease among African Americans. Despite the availability of effective pharmacotherapies and indications for some tailored pharmacotherapies for African Americans (eg, heart failure medications), disease management is less effective among African Americans, yielding higher mortality. Explanations for these persistent disparities in cardiovascular disease are multifactorial and span from the individual level to the social environment. The strategies needed to promote equity in the cardiovascular health of African Americans require input from a broad set of stakeholders, including clinicians and researchers from across multiple disciplines. © 2017 American Heart Association, Inc.

  9. Electricity regulation and electricity market reforms in China

    International Nuclear Information System (INIS)

    Ngan, H.W.

    2010-01-01

    The electricity industry of China has been in a process of reforms since the 1980s. This paper gives a review on the three main stages of reforms in China so as to trace out key features of various reform measures including those for power investment financing, the separation between government and power enterprises, and the division between power generation firms and power grids. The findings suggest that further regulatory change in China's electricity market reform is necessary when integration of the electricity markets and increased competition are paving the way ahead for a market-oriented structure. Prospective electricity regulation in the form of a strong legal system and effective institutions that protect market competition and promote appropriate incentives for efficiency are suggested in the paper.

    2017-08-01

    Indigenous Americans (i.e., Native/American Indians, AK natives, Pacific Islanders) have consistently volunteered for military service at greater rates than any other ethnic group, including the majority culture, since the early days of the country. This article is an introduction to the special section which includes a number of outstanding papers that provide an innovative and compelling effort to overcome the challenges of casualties from war and render effective and culturally informed care. These manuscripts describe culturally appropriate considerations of suicide (O'Keefe), family involvement and access to care (Whealin), and telehealth for treatment of rural Native veterans (Goss). Challenging and complex treatment needs call for equally mindful and competent approaches. These authors and providers present compelling examples of addressing these needs in working with our Wounded Warriors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  11. Electricity costs in liberalized market

    International Nuclear Information System (INIS)

    Barkans, J.; Junghans, G.

    2006-01-01

    In the liberalized electricity market the flexible demand determines the operation of power plants. Under market conditions the producers are forced to compete, and their power plants are normally loaded in order of increasing prices. The electricity costs consist of fixed and variable components, and the competition among producers simulates minimization of both the components. Considering the fixed costs (including maintenance, depreciation, capital costs and other permanent costs not depending on production) to be known, the total electricity costs in different operating conditions are based on the economic characteristics and the equipment load of a power plant. The paper describes the method for determination of electricity costs for condensing thermal power plants with permanent steam take-off for regeneration purposes and adjustable steam take-off for the needs of local heat energy consumers. The marginal costs for CHP plants are determined considering a number of different steam take-off from a turbine. At the electricity cost determination, auxiliary services also are taken into account. These can be reduced by adjusting the rotational speed of electric motors. The paper also shows how to determine the electricity costs for gas turbines, combined cycle gas turbines, and nuclear power plants. The position of hydro power plants among other PPs in the free market is also analysed. (authors)

  12. Electric fields in the magnetosphere

    International Nuclear Information System (INIS)

    Faelthammar, C.G.

    1989-12-01

    The electric field plays an important role in the complex plasma system called the magnetosphere. In spite of this, direct measurement of this quantity are still scarce except in its lowest-altitude part, i.e. the ionosphere. The large scale ionospheric electric field has been determined from measurement on the ground and in low satellite orbit. For most of the magnetosphere, our concepts of the electric field have mostly been based on theoretical considerations and extrapolations of the ionspheric electric field. Direct, in situ, electric field measurements in the outer parts of the magnetosphere have been made only relatively recently. A few satellite missions. most recently the Viking mission, have extended the direct empirical knowledge so as to include major parts of the magnetosphere. These measurements have revealed a number of unexpected features. The actual electric field has been found to have unexpectedly strong space and time variations, which reflect the dynamic nature of the system. Examples are give of measured electric fields in the plasmasphere, the plasmasheet, the neutral sheet, the magnetotail, the flanks of the magnetosphere, the dayside magnetopause and the auroral acceleration region.

    Baron, R.L.; Godec, M.L.

    1997-01-01

    Rapid changes in U.S. gas market developments and key factors that are likely to change future market outlook were reviewed. Currently, the biggest challenges facing the North American gas industry are deregulation in the electric power industry, technological advances, Canadian exports, environmental considerations, and new sources of natural gas from Mexico and Sable Island. Forces driving the natural gas demand include technological advances, growth in gas demand by electric utilities, and expansion of pipeline capacity. Uncertainties and threats to natural gas use include the rising cost of environmental compliance, the continued use of coal for power generation, and the Alliance Pipeline development. Technological advances such as 3-D seismic, horizontal drilling, improved completion techniques, longer-life bits, improved control systems, and reduced project cycle time, have been credited for producers now finding more gas reserves per well drilled than a decade ago. Present estimates of technically recoverable gas resources in North America run to about 2,500 trillion cubic feet

  1. Natural gas and electricity convergence

    International Nuclear Information System (INIS)

    Calger, C.

    1998-01-01

    Convergence between the gas and electricity industries was described as a means for creating an increasingly more efficient energy market where prices and fundamental relationships exist between gas and electricity. Convergence creates new opportunities for producers and consumers. Convergence will likely lead to the disaggregation of the electricity and gas industry into segments such as: (1) power generation and production, (2) transmission wires and pipelines, (3) wholesale merchants, (4) distribution wires and pipelines, and (5) retail marketing, services and administration. The de-integration of integrated utilities has already begun in the U.S. energy markets and retail open access is accelerating. This retail competition will create very demanding customers and the changing risk profile will create new issues for stakeholders. The pace of reform for the telecommunications, airlines, natural gas and electricity industries was graphically illustrated to serve as an example of what to expect. The different paths that the industry might take to deregulation (aggressively embrace reform, or defensively blocking it), and the likely consequences of each reaction were also described. A map indicating where U.S. electric and natural gas utility merger and acquisition activities have taken place between 1994-1997, was included. Another map showing the physical asset positions of the Enron grid, one of the largest independent oil and gas companies in the U.S., with increasing international operations, including an electric power transmission and distribution arm, was also provided as an illustration of a fully integrated energy market company of the future. 9 figs

    1988-06-01

    The data in this report are presented for a wide audience including Congress, Federal and State agencies, the electric utility industry, and the general public. The Energy Information Administration (EIA) collected the information in this report to fulfill its data collection and dissemination responsibilities as specified in the Federal Energy Administration Act of 1974 (Public Law 93-275) as amended. The Electric Power Monthly contains information from three data sources: the Form EIA-759, 'Monthly Power Plant Report'; the Federal Energy Regulatory Commission (FERC) Form 423, 'Monthly Report of Cost and Quality of Fuels for Electric Plants ; and the Form EIA-826, M onthly Electric Sales and Revenue Report with State Distributions'. The Form EIA-759 collects data from all operators of electric utility generating plants (except those having plants solely on standby), approximately 800 of the more than 3,200 electric utilities in the United States. To reduce the reporting burden for utilities, the FERC Form 423 and Form EIA-826 data are based on samples, which cover less than 100 percent of all central station generating utilities. The FERC Form 423 collects data from steam-electric power generating plants with a combined installed nameplate capacity of 50 megawatts or larger (approximately 230 electric utilities). The 50-megawatt threshold was established by FERC. The Form EIA-826 collects sales and revenue data in the residential, commercial, industrial, and other sectors of the economy. Other sales data collected include public street and highway lighting, other sales to public authorities, sales to railroads and railways, and interdepartmental sales. Respondents to the Form EIA-826 were statistically chosen and include approximately 225 privately and publicly owned electric utilities from a universe of more than 3,200 utilities. The sample selection for the Form EIA-826 is evaluated annually. Currently, the Form EIA-826 data account for approximately 83 percent

    2008-07-01

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) reviews work done on the development of new power transmission planning tools for restructured power networks. These are needed in order to face the challenges that arise due to economic, environmental and social issues. The integration of transmission, generation and energy policy planning in order to support a common strategy with respect to sustainable electricity networks is discussed. In the first phase of the project the main focus was placed on the definition of criteria and inputs that are most likely to affect sustainable transmission expansion plans. Models, concepts, and methods developed in order to study the impact of the internalisation of external costs in power production are examined. To consider external costs in the planning process, a concurrent software tool has been implemented that is capable of studying possible development scenarios. The report examines a concept that has been developed to identify congested transmission lines or corridors and evaluates the dependencies between the various market participants. The paper includes a set of three appendices that include a paper on the 28{sup th} USAEE North American conference, an abstract from Powertech 2009 and an SFOE report from July 2008.

    The radio-frequency (rf) dosimeter developed by the Oak Ridge National Laboratory is a portable, pocket-sized cumulative-dose recording device designed to detect and record the strengths and durations of electric fields present in the work areas of naval vessels. The device measures an integrated dose and records the electric fields that exceed the permissible levels set by the American National Standards Institute. Features of the rf dosimeter include a frequency range of 30 MHz to 10 GHz and a three-dimensional sensor. Data obtained with the rf dosimeter will be used to determine the ambient field-strength profile for shipboard personnel over an extended time. Readings are acquired and averaged over a 6-min period corresponding to the rise time of the core body temperature. These values are stored for up to 6 months, after which the data are transferred to a computer via the dosimeter's serial port. The rf dosimeter should increase knowledge of the levels of electric fields to which individuals are exposed. 5 refs., 4 figs

    What is wrong in the American parochialism about foreign languages is the assumption that language acquisition is a cosmetic gain, without any immediate or forseeable practical use. Languages will only be learned effectively when Americans learn that they can be used in getting tasks accomplished. (MSE)

    Chen, C; Edwards, K; Young, B; Greenberger, E

    2001-02-01

    The authors examined attitudes and behaviors regarding close relationships between European and Asian Americans, with a particular emphasis on 5 major subgroups of Asian Americans (Chinese, Japanese, Korean, Vietnamese, and Filipino Americans). Participants were 218 Asian American college students and 171 European American college students attending a culturally diverse university. The European Americans did not differentiate among the various subgroups of Asian Americans. Their attitudes regarding close relationships were less positive toward Asian Americans than toward Mexican and African Americans, a finding contrary to the prediction of social exchange theory (H. Tajfel, 1975). In contrast to the European Americans' view of homogeneity among Asian Americans, the 5 major subgroups of Asian Americans expressed a distinctive hierarchy of social preference among themselves. Results are discussed in terms of their implications for future research on interethnic relations involving Asian Americans.

    The Canadian Electrical Association annual report for 1993 is presented. The Association's objectives include providing a forum for studying, discussing, and exchanging information related to the electric utility industry; developing and promotion of policies on production, distribution, and utilization of electricity; acting as an industry advocate before the public and governments; and facilitating Canadian involvement in international activities affecting the electric utility industry. Association members include individuals, 35 corporate utilities, 35 corporate manufacturers, 180 associate companies, and representation from contractors, consultants, academia, and government. Association activities in helping utilities to control costs, sponsoring research and development, enhancing value of electricity to members' customers, and meeting public responsibilities are reviewed. Selected research and development projects are summarized and statistics on Canadian electricity production, generating capacity, energy demand, electricity prices, and exports are included. Lists of research and development projects awarded and completed in 1992 are appended. 10 figs., 2 tabs

  16. Electric Potential and Electric Field Imaging with Applications

    Generazio, Ed

    2016-01-01

    The technology and techniques for remote quantitative imaging of electrostatic potentials and electrostatic fields in and around objects and in free space is presented. Electric field imaging (EFI) technology may be applied to characterize intrinsic or existing electric potentials and electric fields, or an externally generated electrostatic field may be used for (illuminating) volumes to be inspected with EFI. The baseline sensor technology, electric field sensor (e-sensor), and its construction, optional electric field generation (quasistatic generator), and current e-sensor enhancements (ephemeral e-sensor) are discussed. Demonstrations for structural, electronic, human, and memory applications are shown. This new EFI capability is demonstrated to reveal characterization of electric charge distribution, creating a new field of study that embraces areas of interest including electrostatic discharge mitigation, crime scene forensics, design and materials selection for advanced sensors, dielectric morphology of structures, inspection of containers, inspection for hidden objects, tether integrity, organic molecular memory, and medical diagnostic and treatment efficacy applications such as cardiac polarization wave propagation and electromyography imaging.

  18. IEA Statistics 1993: electricity information

    International Nuclear Information System (INIS)

    1994-01-01

    Gross electricity production in 1993 in the OECD (including generation from pumped storage plants) was 7 466 TWh, a rise of 1.2 per cent from the level of gross production in 1992 (Tables 1 and 3). Nuclear plants accounted for 24.2 per cent of total gross electricity production in 1993, hydroelectric plants 16.7 per cent, total thermal plants 58.7 per cent and geothermal and other renewables 0.4 per cent. In 1992 total OECD heat production that is sold to third parties by public producers was 25 Mtoe (Table 6). About 86 per cent of this heat (21.6 Mtoe) was produced in CHP plants, about 12 per cent (3.1 Mtoe) in heat plants, and the remainder (0.3 Mtoe) in nuclear power plants (in Canada and Switzerland only). Based on preliminary data, apparent consumption of electricity (gross production plus imports less exports) in 1993 in OECD was 7 474 TWh. The corresponding figure for 1992 was 7 379 TWh, indicating a rise of 1.3 per cent in apparent electricity consumption in OECD countries in 1993. OECD countries imported a total of 219 TWh of electricity in 1993 (including from other OECD countries) and exported 211 TWh (including to other OECD countries). Accordingly, net imports of electricity in 1993 amounted to 7.7 TWh. Real electricity prices (as measured by the indices of real energy prices) in the OECD fell slightly in 1993 from 1992 levels for both industry and household end-users (Table 20). Electricity prices for industrial consumers vary widely across OECD countries. Based on data that are available for 1993, prices varied from 3.3 US cents per kWh in New Zealand to 12.1 US cents per kWh in Portugal. Electricity prices for industry are reported in Tables 24 and 25. Electricity prices for domestic consumers also vary widely across OECD countries. Based on data that are available for 1993, prices varied from 5.8 US cents per kWh in New Zealand to 18.0 US cents per kWh in Denmark (Tables 26 and 27)

  19. American Indian Men's Perceptions of Breast Cancer Screening for American Indian Women.

    Screening, especially screening mammography, is vital for decreasing breast cancer incidence and mortality. Screening rates in American Indian women are low compared to other racial/ethnic groups. In addition, American Indian women are diagnosed at more advanced stages and have lower 5-year survival rate than others. To better address the screening rates of American Indian women, focus groups (N=8) were conducted with American Indian men (N=42) to explore their perceptions of breast cancer screening for American Indian women. Our intent was to understand men's support level toward screening. Using a community-based participatory approach, focus groups were audio-taped, transcribed verbatim, and analyzed using a text analysis approach developed by our team. Topics discussed included breast cancer and screening knowledge, barriers to screening, and suggestions to improve screening rates. These findings can guide strategies to improve knowledge and awareness, communication among families and health care providers, and screening rates in American Indian communities.
