  1. Reviving the United States' Commitment to Pakistan and Afghanistan

    Full Text Available As President Obama is in the midst of deciding whether additional U.S.combat forces are needed in Afghanistan in addition to the 21,000 troops recently committed, he must realize that additional armed forces are only a stopgap measure in Afghanistan's downward spiral into an 'undergoverned' failed state. Similarly, as Pakistan's fragile and fractured civilian government continues to appease the Tehrik-i-Taliban Pakistan (TTP, an umbrella organization of Pakistani Pashtun tribesmen with Taliban cultural values led by Baitullah Mehsud and others, it comes closer to the concept of a "misgoverned" failed state, possessing a small arsenal of nuclear arms. The problem for the U.S. administration is that neither of these countries can be allowed to fall further into disrepair. At the same time each requires a different and unique approach to the threat of "Talibanization" that faces each country—the control of territory within each country by Islamic radicals seeking to impose their ultraconservative interpretation of shar'ia law onto the general populace. Generally acknowledged is the belief that what has tentatively worked in Iraq, that is, the additional U.S. troops and employment of former Sunni insurgents to help fight foreign fighters associated with al-Qaida, will not work in either Afghanistan or Pakistan. While a regional approach to the conflict in these two countries is warranted, Afghanistan and Pakistan are on two different economic, social, and political playing fields. Hence, there cannot be a one-size-fits-all solution for the two countries, especially one that draws on the Iraq playbook. In addition to its internal political problems, Pakistan also faces the issue of al-Qaida and Taliban training camps positioned in its literal back yard, the Federally Administered Tribal Areas (FATA or Tribal Areas. Resolution of the War on Terror cannot come to fruition without addressing the problems that exist in the Tribal Areas. This largely

  2. Relative Importance of Human Resource Practices on Affective Commitment and Turnover Intention in South Korea and United States

    Full Text Available The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both the United States and South Korea. While internal mobility was a stronger predictor of affective commitment for the United States sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the United States, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research.

  3. Committed Vulnerability to Extreme Weather Events in the United States (Invited)

    2013-12-01

    Despite improvements in disaster risk management in the United States, a trend toward increasing economic losses from extreme weather events has been observed. This trend has been attributed to growth in socioeconomic exposure to extremes driven by the concentration of population and wealth on hazardous landscapes. As geographic patterns of demography and economic development are associated with strong path dependence, the United States is ';locked-in' to future increases in exposure and associated economic losses in the decades ahead, irrespective of the influence of climate change. To understand the influence of path dependence on past and future losses, an index of potential socioeconomic exposure was developed at the U.S. county level based upon population size and inflation-adjusted wealth proxies. Since 1960, exposure has increased preferentially in the U.S. Southeast, particularly coastal and urban counties and Southwest relative to the Great Plains and Northeast. Projected changes in exposure from 2009 to 2054 based upon scenarios of future demographic and economic change suggest a long-term commitment to increasing, but spatially heterogeneous, exposure to extremes, independent of climate change. The implications of this path dependence are examined in the context of several natural hazards. Annualized county-level losses from 1960-2008 for five climate-related natural hazards were normalized to 2009 values and then scaled based upon projected changes in exposure and two different estimates of the exposure elasticity of losses. Results indicate that losses from extreme events will grow by a factor of 1.3-1.7 and 1.8-3.9 by 2025 and 2050, respectively, with the exposure elasticity representing a major source of uncertainty. At more local scales, however, such as rapidly growing metropolitan areas, losses are anticipated to grow more rapidly. As such, improving understanding of the societal implications of the extreme weather events of the future

  5. State commitment to public participation

    International Nuclear Information System (INIS)

    Baranski, S.C.; Serie, P.J.

    1989-01-01

    This paper discusses how New York's approach to developing a new low-level radioactive waste disposal facility demonstrates a commitment to responsibility for waste generated within its borders. There is a strong, legislated commitment to meeting federal milestones and starting from scratch to select a suitable site and disposal method. Equally strong is the state's commitment to meaningful public participation. A statewide program is underway, including public information and education and interactive techniques. The public participation program is fully integrated with the technical and policy activities of the New York State Low-Level Radioactive Waste Siting Commission at all levels. The program is designed to progressively tailor techniques and coverage to the steps in site and method selection, and will focus most intensively on the communities where four sites are selected for full characterization

  6. The application of civil commitment law and practices to a case of delusional disorder: a cross-national comparison of legal approaches in the United States and the United Kingdom.

    Science.gov (United States)

    Fennell, Philip; Goldstein, Robert Lloyd

    2006-01-01

    Legal approaches to civil commitment in the United States and the United Kingdom are compared. A concise overview of the historical evolution of civil commitment in both countries precedes a discussion of the present scheme of commitment standards in each system. These current standards in U.S. and U.K. jurisdictions are then applied to a hypothetical case of delusional disorder. A discussion of the constructive use of civil commitment in patients with delusional disorder who may be dangerous focuses on its value as a preventive measure against potential harm to self or others, as well as the pros and cons of coercive assessment and treatment. Despite the many differences in approach to commitment, the authors concur that in both countries the patient with delusional disorder was committable before the commission of a serious criminal offense.

    2009-07-01

    A model of Unit Commitment to hydrothermal systems that includes the costs of start/stop of generators is proposed. These costs has been neglected in a good part of the programming models for operation of hydrothermal systems (pre-dispatch). The impact of the representation of costs in total production costs is evaluated. The proposed model is solved by a hybrid methodology, which involves the use of genetic algorithms (to solve the entire part of the problem) and sequential quadratic programming methods. This methodology is applied to the solution of an IEEE test system. The results emphasize the importance of representation of the start/stop in the generation schedule.

When implemented for a test system, the results show that...

  12. Unit commitment with probabilistic reserve: An IPSO approach

    International Nuclear Information System (INIS)

    Lee, Tsung-Ying; Chen, Chun-Lung

    2007-01-01

    This paper presents a new algorithm for solution of the nonlinear optimal scheduling problem. This algorithm is named the iteration particle swarm optimization (IPSO). A new index, called iteration best, is incorporated into particle swarm optimization (PSO) to improve the solution quality and computation efficiency. IPSO is applied to solve the unit commitment with probabilistic reserve problem of a power system. The outage cost as well as fuel cost of thermal units was considered in the unit commitment program to evaluate the level of spinning reserve. The optimal scheduling of on line generation units was reached while minimizing the sum of fuel cost and outage cost. A 48 unit power system was used as a numerical example to test the new algorithm. The optimal scheduling of on line generation units could be reached in the testing results while satisfying the requirement of the objective function

  13. Thunderstorm Algorithm for Determining Unit Commitment in Power System Operation

    2016-12-01

    Full Text Available Solving the unit commitment problem is an important task in power system operation for deciding a balanced power production between various types of generating units under technical constraints and environmental limitations. This paper presents a new intelligent computation method, called the Thunderstorm Algorithm (TA, for searching the optimal solution of the integrated economic and emission dispatch (IEED problem as the operational assessment for determining unit commitment. A simulation using the IEEE-62 bus system showed that TA has smooth convergence and is applicable for solving the IEED problem. The IEED’s solution is associated with the total fuel consumption and pollutant emission. The proposed TA method seems to be a viable new approach for finding the optimal solution of the IEED problem.

  14. Unit Commitment for Systems With Significant Wind Penetration

    Tuohy, Aidan; Meibom, Peter; Denny, E.

    2009-01-01

    The stochastic nature of wind alters the unit commitment and dispatch problem. By accounting for this uncertainty when scheduling the system, more robust schedules are produced, which should, on average, reduce expected costs. In this paper, the effects of stochastic wind and load on the unit...... commitment and dispatch of power systems with high levels of wind power are examined. By comparing the costs, planned operation and performance of the schedules produced, it is shown that stochastic optimization results in less costly, of the order of 0.25%, and better performing schedules than deterministic...... optimization. The impact of planning the system more frequently to account for updated wind and load forecasts is then examined. More frequent planning means more up to date forecasts are used, which reduces the need for reserve and increases performance of the schedules. It is shown that mid-merit and peaking...

    2003-01-01

    Upon pressure from the United States Congress, the US Department of Energy had to withdraw from further American participation in the ITER Engineering Design Activities after the end of its commitment to the EDA in July 1998. In the years since that time, changes have taken place in both the ITER activity and the US fusion community's position on burning plasma physics. Reflecting the interest in the United States in pursuing burning plasma physics, the DOE's Office of Science commissioned three studies as part of its examination of the option of entering the Negotiations on the Agreement on the Establishment of the International Fusion Energy Organization for the Joint Implementation of the ITER Project. These were a National Academy Review Panel Report supporting the burning plasma mission; a Fusion Energy Sciences Advisory Committee (FESAC) report confirming the role of ITER in achieving fusion power production, and The Lehman Review of the ITER project costing and project management processes (for the latter one, see ITER CTA Newsletter, no. 15, December 2002). All three studies have endorsed the US return to the ITER activities. This historical decision was announced by DOE Secretary Abraham during his remarks to employees of the Department's Princeton Plasma Physics Laboratory. The United States will be working with the other Participants in the ITER Negotiations on the Agreement and is preparing to participate in the ITA

    1985-01-01

    In the United States, the advanced technologies have been applied to uranium enrichment as a means by which it can be assured that nuclear fuel cost will remain competitive in the future. The United States is strongly committed to the development of advanced enrichment technology, and has brought both advanced gas centrifuge (AGC) and atomic vapor laser isotope separation (AVLIS) programs to a point of significant technical refinement. The ability to deploy advanced technologies is the basis for the confidence in competitive future price. Unfortunately, the development of advanced technologies is capital intensive. The year 1985 is the key year for advanced technology development in the United States, since the decision on the primary enrichment technology for the future, AGC or AVLIS, will be made shortly. The background on the technology selection process, the highlights of AGC and AVLIS programs and the way to proceed after the process selection are described. The key objective is to maximize the sales volume and minimize the operating cost. This will help the utilities in other countries supply low cost energy on a reliable, long term basis. (Kako, I.)

  20. Hidden power system inflexibilities imposed by traditional unit commitment formulations

    International Nuclear Information System (INIS)

    Morales-España, Germán; Ramírez-Elizondo, Laura; Hobbs, Benjamin F.

    2017-01-01

    Highlights: • Quality and accuracy of traditional-energy- and power-based UCs are evaluated. • Real-time performance evaluation simulating “perfect” stochastic UCs. • Ideal energy-based stochastic UC formulations impose hidden system inflexibilities. • A deterministic power-based UC may outperform an ideal energy-based stochastic UC. • Power-based UC overcomes flaws of energy-based UC: lower cost and wind curtailment. - Abstract: Approximations made in traditional day-ahead unit commitment model formulations can result in suboptimal or even infeasible schedules for slow-start units and inaccurate predictions of actual costs and wind curtailment. With increasing wind penetration, these errors will become economically more significant. Here, we consider inaccuracies from three approximations: the use of hourly intervals in which energy production from each generator is modeled as being constant; the disregarding of startup and shutdown energy trajectories; and optimization based on expected wind profiles. The results of unit commitment formulations with those assumptions are compared to models that: (1) use a piecewise-linear power profiles of generation, load and wind, instead of the traditional stepwise energy profiles; (2) consider startup/shutdown trajectories; and (3) include many possible wind trajectories in a stochastic framework. The day-ahead hourly schedules of slow-start generators are then evaluated against actual wind and load profiles using a model real-time dispatch and quick-start unit commitment with a 5 min time step. We find that each simplification usually causes expected generation costs to increase by several percentage points, and results in significant understatement of expected wind curtailment and, in some cases, load interruptions. The inclusion of startup and shutdown trajectories often yielded the largest improvements in schedule performance.

  1. Multi-area unit commitment with ramp-rate limits

    Wang, C.; Shahidehpour, S.M.

    1992-01-01

    This paper reports that there are two tasks considered in power system generation scheduling. One is the unit commitment which determines the unit start up and shut down schedules in order to minimize the system fuel expenditure. The other is the economic dispatch which assigns the system load demand to the committed generating units for minimizing the power generation cost. The economic operation attracts a great deal of attention as a modest reduction in percentage fuel cost leads to a large saving in the system operation costs. Many studies for power system generation scheduling have successfully applied various mathematical algorithms such as Lagrangian relaxation, dynamic programming, and artificial intelligence techniques e.g., expert systems, artificial neural networks (ANN), etc. The AI techniques have incorporated the system practical operational policies in the mathematical techniques to improve system models considerably. The mechanism of ANN simulates the learning process of the human brain. One class of ANN learns the knowledge through examples, or training facts, composed by various inputs and their corresponding outputs. The extent of the intelligibility of ANN depends upon the diversity of the training facts. For an input which is not in the training facts, the trained ANN can estimate an output based on its previous knowledge about the problem

  2. Quantum Bit Commitment and the Reality of the Quantum State

    Science.gov (United States)

    Srikanth, R.

    2018-01-01

    Quantum bit commitment is insecure in the standard non-relativistic quantum cryptographic framework, essentially because Alice can exploit quantum steering to defer making her commitment. Two assumptions in this framework are that: (a) Alice knows the ensembles of evidence E corresponding to either commitment; and (b) system E is quantum rather than classical. Here, we show how relaxing assumption (a) or (b) can render her malicious steering operation indeterminable or inexistent, respectively. Finally, we present a secure protocol that relaxes both assumptions in a quantum teleportation setting. Without appeal to an ontological framework, we argue that the protocol's security entails the reality of the quantum state, provided retrocausality is excluded.

    2015-12-11

    This paper addresses the study of symmetry in Unit Commitment (UC) problems solved by Mixed Integer Linear Programming (MILP) formulations, and using Linear Programming based Branch & Bound MILP solvers. We propose three sets of symmetry breaking constraints for UC MILP formulations exhibiting symmetry, and its impact on three UC MILP models are studied. The case studies involve the solution of 24 instances by three widely used models in the literature, with and without symmetry breaking constraints. The results show that problems that could not be solved to optimality within hours can be solved with a relatively small computational burden if the symmetry breaking constraints are assumed. The proposed symmetry breaking constraints are also compared with the symmetry breaking methods included in two MILP solvers, and the symmetry breaking constraints derived in this work have a distinct advantage over the methods in the MILP solvers.

    Pereira, Isabel; Veloso, Ana; Silva, Isabel Soares; Costa, Patricio

    2017-05-18

    This study explored the relationship between organizational commitment and job satisfaction among workers in family health units. Six family health units in the North of Portugal participated, including 105 health professionals (physicians, nurses, and clinical secretaries). The study used the Portuguese adaptations of the Organizational Commitment Scale by Meyer & Allen (1997) and the Job Satisfaction Survey (Spector, 1985). The results suggest a positive association between organizational commitment and job satisfaction. The professionals are moderately satisfied and committed to the family health units; the most satisfactory aspects are the nature of the work, relationship to coworkers, and communication, while pay is the most unsatisfactory. The affective component of the commitment appears, highlighting the professionals' involvement in (and identification with) the family health units project. The linear regression model proved significant, and organizational commitment explains 22.7% of the variance in job satisfaction. For this sample, organizational commitment predicts job satisfaction.

  7. Integrating generation and transmission networks reliability for unit commitment solution

    International Nuclear Information System (INIS)

    Jalilzadeh, S.; Shayeghi, H.; Hadadian, H.

    2009-01-01

    This paper presents a new method with integration of generation and transmission networks reliability for the solution of unit commitment (UC) problem. In fact, in order to have a more accurate assessment of system reserve requirement, in addition to unavailability of generation units, unavailability of transmission lines are also taken into account. In this way, evaluation of the required spinning reserve (SR) capacity is performed by applying reliability constraints based on loss of load probability and expected energy not supplied (EENS) indices. Calculation of the above parameters is accomplished by employing a novel procedure based on the linear programming which it also minimizes them to achieve optimum level of the SR capacity and consequently a cost-benefit reliability constrained UC schedule. In addition, a powerful solution technique called 'integer-coded genetic algorithm (ICGA)' is being used for the solution of the proposed method. Numerical results on the IEEE reliability test system show that the consideration of transmission network unavailability has an important influence on reliability indices of the UC schedules

    2009-10-09

    We present a computational framework for integrating the state-of-the-art Weather Research and Forecasting (WRF) model in stochastic unit commitment/energy dispatch formulations that account for wind power uncertainty. We first enhance the WRF model with adjoint sensitivity analysis capabilities and a sampling technique implemented in a distributed-memory parallel computing architecture. We use these capabilities through an ensemble approach to model the uncertainty of the forecast errors. The wind power realizations are exploited through a closed-loop stochastic unit commitment/energy dispatch formulation. We discuss computational issues arising in the implementation of the framework. In addition, we validate the framework using real wind speed data obtained from a set of meteorological stations. We also build a simulated power system to demonstrate the developments.

    Science.gov (United States)

    Guo, Sangang

    2017-09-01

    There are two stages in solving security-constrained unit commitment problems (SCUC) within Lagrangian framework: one is to obtain feasible units’ states (UC), the other is power economic dispatch (ED) for each unit. The accurate solution of ED is more important for enhancing the efficiency of the solution to SCUC for the fixed feasible units’ statues. Two novel methods named after Convex Combinatorial Coefficient Method and Power Increment Method respectively based on linear programming problem for solving ED are proposed by the piecewise linear approximation to the nonlinear convex fuel cost functions. Numerical testing results show that the methods are effective and efficient.

    2009-01-01

    Full Text Available This paper presents a new approach to solve short-term unit commitment problem (UCP using Neural Based Tabu Search (NBTS with cooling and banking constraints. The objective of this paper is to find the generation scheduling such that the total operating cost can be minimized, when subjected to a variety of constraints. This also means that it is desirable to find the optimal generating unit commitment in the power system for next H hours. A 7-unit utility power system in India demonstrates the effectiveness of the proposed approach; extensive studies have also been performed for different IEEE test systems consist of 10, 26 and 34 units.

    This paper presents a new approach to solve the short-term unit commitment problem using an evolutionary programming based simulated annealing method. The objective of this paper is to find the generation scheduling such that the total operating cost can be minimized, when subjected to a variety of constraints. This also means that it is desirable to find the optimal generating unit commitment in the power system for the next H hours. Evolutionary programming, which happens to be a global optimisation technique for solving unit commitment Problem, operates on a system, which is designed to encode each unit's operating schedule with regard to its minimum up/down time. In this, the unit commitment schedule is coded as a string of symbols. An initial population of parent solutions is generated at random. Here, each schedule is formed by committing all the units according to their initial status (''flat start''). Here the parents are obtained from a pre-defined set of solution's, i.e. each and every solution is adjusted to meet the requirements. Then, a random recommitment is carried out with respect to the unit's minimum down times. And SA improves the status. The best population is selected by evolutionary strategy. The Neyveli Thermal Power Station (NTPS) Unit-II in India demonstrates the effectiveness of the proposed approach; extensive studies have also been performed for different power systems consists of 10, 26, 34 generating units. Numerical results are shown comparing the cost solutions and computation time obtained by using the Evolutionary Programming method and other conventional methods like Dynamic Programming, Lagrangian Relaxation and Simulated Annealing and Tabu Search in reaching proper unit commitment.

  3. Practical Robust Optimization Method for Unit Commitment of a System with Integrated Wind Resource

    2017-01-01

    Full Text Available Unit commitment, one of the significant tasks in power system operations, faces new challenges as the system uncertainty increases dramatically due to the integration of time-varying resources, such as wind. To address these challenges, we propose the formulation and solution of a generalized unit commitment problem for a system with integrated wind resources. Given the prespecified interval information acquired from real central wind forecasting system for uncertainty representation of nodal wind injections with their correlation information, the proposed unit commitment problem solution is computationally tractable and robust against all uncertain wind power injection realizations. We provide a solution approach to tackle this problem with complex mathematical basics and illustrate the capabilities of the proposed mixed integer solution approach on the large-scale power system of the Northwest China Grid. The numerical results demonstrate that the approach is realistic and not overly conservative in terms of the resulting dispatch cost outcomes.

    Full Text Available This paper describes the use of Chambers-Mallows-Stuck method for simulating stable random variables in the generation of test systems for economic analysis in power systems. A study that focused on generating test electrical systems through fat tail model for unit commitment problem in electrical power systems is presented. Usually, the instances of test systems in Unit Commitment are generated using normal distribution, but in this work, simulations data are based on a new method. For simulating, we used three original systems to obtain the demand behavior and thermal production costs. The estimation of stable parameters for the simulation of stable random variables was based on three generally accepted methods: (a regression, (b quantiles, and (c maximum likelihood, choosing one that has the best fit of the tails of the distribution. Numerical results illustrate the applicability of the proposed method by solving several unit commitment problems.

    Biogas plants contribute a significant share of renewable energy sources (RES) to the electricity system. Most of them are designed to supply constant power generation. In the future biogas plants will most likely become more flexible, scheduling their power generation with respect to market prices. For this purpose power units need extended electrical capacity to convert the continuously produced gas as well as the gas held in storage. When constructing extended capacity at biogas plants, the flexibility premium is the main focus for about 8000 plants which were constructed before August 2014. Additional incomes as a result of selling at higher market prices have been considered, too. However, their relationship to the electrical capacity and storage size of biogas plants was unknown as was the impact on investment valuation. This work has shown how biogas plants with extended capacity can be analyzed when they are operated in power markets, in particular the power spot market and the control reserve markets. Models on the basis of unit commitment have been developed in order to obtain optimized schedules and financial parameters, such as gross income and net present value (NPV), when biogas plants with extended capacity capitalize on prices in each market. The models developed consider several use cases that describe possible ways of participating in German power markets, switching between static and variable gas supply, providing secondary and tertiary control reserve, and claiming the market and flexibility premium. Mixed integer linear programs (MILP) have been developed for the unit commitment of each use case. The model for the unit commitment of providing control reserve with biogas plants made significant progress compared to the state of the art and has been published in (Hochloff, Braun 2014). There are two ways to make use of this model. First of all, the model could be applied to plan daily schedules for the operation of gas plants located at a gas

    This paper reports that at least in the national security arena, the outcomes of bureaucratic infighting and domestic political struggles are not determined wholly by what goes on with the state. Rather struggles among contending groups are greatly affected by what is perceived to be happening outside the nation. Because external conditions give greater potency to some domestic forces over other, the external environment is never neutral in its domestic impact. The decisions of the period 1950-53 discussed above illustrate the point. But so too do the decisions of 1947, 1960-61 and 1969-72. In the 1947 case, Soviet intransigence provoked US nuclear rearmament. In the 1960-61 case, extended deterrent considerations pushed the United States to preserve its again newly discovered nuclear superiority. In the 1969-72 case, a Soviet determination to remain equal forced US acceptance of nuclear equality. And perhaps the best evidence of all, the perpetuation of parity ended the US inclination to resort to nuclear brinkmanship. In each instance, concerns about relative position heavily affected nuclear choice. Finally, the events of the past three years testify to the effects of international events on domestic choice. Under the terms of the 1987 INF Treaty, the two superpowers decided to dismantle and destroy an entire class of missiles of intermediate range (500-3000 kilometers) that both had deployed in Europe in the 1970s and 1980s, and in their June 1990 joint statement on strategic nuclear weapons, President Gorbachev and Brush agreed to cut the number of Soviet and US long range nuclear forces by 30 per cent. This agreement marks a watershed in US-Soviet strategic arm negotiations because for the first time the United States and the Soviet Union agreed in principals to reduce the number of weapons aimed at one another. Between 1985 and 1990 the cold war was brought to a close

    Full Text Available Unit commitment (UC is a non-linear, large scale, complex, mixed-integer combinatorial constrained optimization problem. This paper proposes, a new hybrid approach for generating unit commitment schedules using swarm intelligence learning rule based neural network. The training data has been generated using dynamic programming for machines without valve point effects and using genetic algorithm for machines with valve point effects. A set of load patterns as inputs and the corresponding unit generation schedules as outputs are used to train the network. The neural network fine tunes the best results to the desired targets. The proposed approach has been validated for three thermal machines with valve point effects and without valve point effects. The results are compared with the approaches available in the literature. The PSO-ANN trained model gives better results which show the promise of the proposed methodology.

    2016-01-01

    Recent years have witnessed the ever increasing renewable penetration in power generation systems, which entails modern unit commitment problems with modelling and computation burdens. This study aims to simulate the impacts of manifold uncertainties on system operation with emission concerns. First, probability theory and fuzzy set theory are applied to jointly represent the uncertainties such as wind generation, load fluctuation and unit outage that interleaved in unit commitment problems. Second, a Value-at-Risk-based multi-objective approach is developed as a bridge of existing stochastic and robust unit commitment optimizations, which not only captures the inherent conflict between operation cost and supply reliability, but also provides easy-to-adjust robustness against worst-case scenarios. Third, a multi-objective algorithm that integrates fuzzy simulation and particle swarm optimization is developed to achieve approximate Pareto-optimal solutions. The research effectiveness is exemplified by two case studies: The comparison between test systems with and without generation uncertainty demonstrates that this study is practicable and can suggest operational insights of generation mix systems. The sensitivity analysis on Value-at-Risk proves that our method can achieve adequate tradeoff between performance optimality and robustness, thus help system operators in making informed decisions. Finally, the model and algorithm comparisons also justify the superiority of this research. - Highlights: • Probability theory and fuzzy set theory are used to describe different uncertainties. • A Value-at-Risk-based multi-objective unit commitment model is proposed. • An improved multi-objective particle swarm optimization algorithm is developed. • The model achieves adequate trade-off between performance optimality and robustness. • The algorithm can obtain convergent and diversified Pareto fronts.

    Highlights: • Thermal unit commitment is considered in hydrothermal generation scheduling (SHTGS). • Two newly proposed promising optimization algorithms are combined to solving SHTGS. • The proposed method is enhanced by integrating a chaotic local search strategy. • Heuristic search strategies are applied to handle the constraints of the SHTGS. • The results verify the proposed method is feasible and efficient for handling SHTGS. - Abstract: This paper establishes a model to deal with the short-term hydrothermal generation scheduling (SHTGS) problem. The problem is composed of three interconnected parts: short-term hydrothermal coordination, thermal unit commitment and economic load dispatch. An efficient hybrid method composed of chaotic backtracking search optimization algorithm and binary charged system search algorithm (CBSA–BCSS) is proposed to solve this problem. In order to analyze the effect of the chaotic map on the performance of the method, three different chaotic maps are adopted to integrate into the proposed method and the corresponding consequences are achieved. Furthermore, efficient heuristic search strategies are adopted to handle with the complicated constraints of the SHTGS system. Finally, a hydrothermal unit commitment system is utilized to verify the feasibility and effectiveness of the proposed method. The results demonstrate the efficiency of the hybrid optimization method and the appropriation of the constraint handling strategies. The comparison of the solutions achieved by different methods shows that the proposed method has higher efficiency in terms of solving SHTGS problem

In the examination of the geologic possibilities for finding new deposits-in many respects the principal innovative contributions of this volume-we asked the authors to frankly apply the limits of their ingenuity and not only to summarize current theories but also to express their own intuitive ideas, however speculative and unconventional they may seem, that have come from years of study devoted to the origin of mineral deposits. Readers will see that some authors have speculated more courageously than others. In any case, we believe readers will find all the chapters interesting, and many stimulating; and a few we believe can be frankly characterized as intellectually exciting. Most chapters include a section on prospecting techniques, and a summary of geologic or related problems on which the authors believe research might be most fruitful in the continuing efforts to find new resources. An integral part of the book is the bibliographic material cited at the conclusion of each chapter, in lieu of repetition of detailed descriptions already in print. Index and "spot" maps are not included in most chapters because they are available elsewhere, and in many cases with more detail than could possibly be included here. Maps showing the distribution of known deposits of many commodities in the United States are available in the Mineral Resource (MR) map series of the U.S. Geological Survey and in the National Atlas of the United States. The first three chapters deal not with resources of specific commodities but with general information that is pertinent to the study of mineral resources. In the introductory chapter we discuss the purposes of the book, the distinctions between reserves and various categories of resources, and some general conclusions drawn from our view of the book in its entirety. In the second chapter V. E. McKelvey discusses the problems of

    The uncertainties of renewable energy have brought great challenges to power system commitment, dispatches and reserve requirement. This paper presents a comparative study on integration of renewable generation uncertainties into SCUC (stochastic security-constrained unit commitment) considering reserve and risk. Renewable forecast uncertainties are captured by a list of PIs (prediction intervals). A new scenario generation method is proposed to generate scenarios from these PIs. Different system uncertainties are considered as scenarios in the stochastic SCUC problem formulation. Two comparative simulations with single (E1: wind only) and multiple sources of uncertainty (E2: load, wind, solar and generation outages) are investigated. Five deterministic and four stochastic case studies are performed. Different generation costs, reserve strategies and associated risks are compared under various scenarios. Demonstrated results indicate the overall costs of E2 is lower than E1 due to penetration of solar power and the associated risk in deterministic cases of E2 is higher than E1. It implies the superimposed effect of uncertainties during uncertainty integration. The results also demonstrate that power systems run a higher level of risk during peak load hours, and that stochastic models are more robust than deterministic ones. - Highlights: • An extensive comparative study for renewable integration is presented. • A novel scenario generation method is proposed. • Wind and solar uncertainties are represented by a list of prediction intervals. • Unit commitment and dispatch costs are discussed considering reserve and risk.

    Cheat sensitive quantum bit commitment is a most important and realizable quantum bit commitment (QBC) protocol. By taking advantage of quantum mechanism, it can achieve higher security than classical bit commitment. In this paper, we propose a QBC schemes based on pre- and post-selected quantum states. The analysis indicates that both of the two participants' cheat strategies will be detected with non-zero probability.

    Full Text Available Setiap unit pembangkit yang beroperasi untuk memenuhi permintaan beban mempunyai jadwal operasi yang berbeda-beda. Hal ini disebabkan oleh perbedaan karakteristik input-output yang khas dari setiap unit. Untuk memperoleh biaya total pembangkitan yang ekonomis dibutuhkan penjadwalan nyala-padam unit pembangkit yang terhubung pada sistem tenaga listrik, yang dikenal sebagai unit commitment (UC. Penjadwalan unit pembangkit pada suatu sistem tenaga listrik memiliki banyak pertimbangan, seperti cadangan berputar (spinning reserve, waktu menyala minimal (minimum up time, waktu padam minimal (minimum down time, rentang daya output unit pembangkit dan lain-lain. Selain itu, fungsi biaya pembangkitan unit yang mengoperasikan katup uap untuk mengimbangi perubahan beban menyebabkan persamaan fungsi biaya menjadi tidak mulus. Fungsi biaya tidak mulus mempersulit penjadwalan ekonomis unit pembangkit. Tugas akhir ini mengajukan Firefly Algorithm (FA untuk menyelesaikan penjadwalan UC. FA merupakan algoritma yang sederhana, tetapi handal dalam menyelesaikan permasalahan optimisasi. UC yang diajukan menggunakan fungsi biaya tidak mulus. Dengan metode tersebut, diharapkan permasalahan penjadwalan unit pembangkit dapat terselesaikan dengan baik dan optimal sehingga memperoleh biaya total pembangkitan yang ekonomis.

  3. Improved Genetic Algorithm-Based Unit Commitment Considering Uncertainty Integration Method

    2018-05-01

    Full Text Available In light of the dissemination of renewable energy connected to the power grid, it has become necessary to consider the uncertainty in the generation of renewable energy as a unit commitment (UC problem. A methodology for solving the UC problem is presented by considering various uncertainties, which are assumed to have a normal distribution, by using a Monte Carlo simulation. Based on the constructed scenarios for load, wind, solar, and generator outages, a combination of scenarios is found that meets the reserve requirement to secure the power balance of the power grid. In those scenarios, the uncertainty integration method (UIM identifies the best combination by minimizing the additional reserve requirements caused by the uncertainty of power sources. An integration process for uncertainties is formulated for stochastic unit commitment (SUC problems and optimized by the improved genetic algorithm (IGA. The IGA is composed of five procedures and finds the optimal combination of unit status at the scheduled time, based on the determined source data. According to the number of unit systems, the IGA demonstrates better performance than the other optimization methods by applying reserve repairing and an approximation process. To account for the result of the proposed method, various UC strategies are tested with a modified 24-h UC test system and compared.

    Full Text Available This paper presents a new approach to solve the profit based multi area unit commitment problem (PBMAUCP using an evolutionary programming based particle swarm optimization (EPPSO method. The objective of this paper is to maximize the profit of generation companies (GENCOs with considering system social benefit. The proposed method helps GENCOs to make a decision, how much power and reserve should be sold in markets, and how to schedule generators in order to receive the maximum profit. Joint operation of generation resources can result in significant operational cost savings. Power transfer between the areas through the tie lines depends upon the operating cost of generation at each hour and tie line transfer limits. The tie line transfer limits were considered as a set of constraints during optimization process to ensure the system security and reliability. The overall algorithm can be implemented on an IBM PC, which can process a fairly large system in a reasonable period of time. Case study of four areas with different load pattern each containing 7 units (NTPS and 26 units connected via tie lines have been taken for analysis. Numerical results showed comparing the profit of evolutionary programming-based particle swarm optimization method (EPPSO with conventional dynamic programming (DP, evolutionary programming (EP, and particle swarm optimization (PSO method. Experimental results shows that the application of this evolutionary programming based particle swarm optimization method have the potential to solve profit based multi area unit commitment problem with lesser computation time.

    Before I begin I have to make a disclaimer. That is that I am going to be talking about public perception because I think that is very important. But I do not want to give the impression that I think the public is wrong. I happen to agree with the public's perception of nuclear power, and I want to make that clear. I do not like the current generation of nuclear plants as I have made clear in many statements that I have made. On the other hand, in the long term, I feel that we have only two choices on the supply side, and that is nuclear power and solar electricity. And although I think solar electricity has the best chance, I am realistic enough to know that technologies do not always work the way I want. And so I think it is necessary to have at least some kind of nuclear option available. On the other hand, I do not think just any kind of nuclear technology will do. I want to talk to you about the conditions that I think you have to take into account when you try to design reactors that are publicly acceptable. I look at this as an insurance policy. Again, I do not want to be misquoted: I think nuclear power should be considered as an insurance policy, not as our first line of defense. Having made those disclaimers, what we need to do is set out a problem statement. The problem statement I set out is, 'How could one design and demonstrate a nuclear reactor that would regain public confidence in the United States, if one chose to do that?' By regaining confidence, I mean regaining sufficient confidence to site reactors at a number of locations. It is a pretty heavy task because the public cannot judge the technical issues. They have to judge the players by their characters and their histories, just as the way we calibrate anyone that knows things that we do not. I have three theses that I think are crucial. The first is that people do not believe in the claims of advocates, of any point of view, not just nuclear power, once the advocates have been proved wrong on

    Full Text Available The prevalence of civil disorder and cultism in higher institutions of learning in Nigeria and the apparent inability of security operatives to stem the tide has continued to be a source of concern to both the Government and Individuals in recent times. This study examines the effect of organisational commitment on job satisfaction among security operatives working in Nigeria universities. In this study a sample of three hundred (300 security operatives were selected from both public and private universities in Kwara State. Data were collected through self-administered questionnaire and analysed through Descriptive, Comparative, Regression analysis and Spearman Rank Correlation. The findings revealed that these security operatives, a positive relationship exists between organisational commitment and job satisfaction with affective commitment having little or no significant relationship and continuance commitment having significant positive relationship. The study also found that the level of affective commitment was significantly lower than the other components. The study thus concludes that there is a significant positive relationship between organisation commitment and job satisfaction amongst the security operatives. Based on the findings, it was recommended that the selected Universities should focus on improving affective and normative commitment among security operatives in order to be able to deal with the problem of high job turnover and poor performance.

    This paper presents a new Three-Stage (THS) approach for solving Unit Commitment (UC) problem. The proposed method has a simple procedure to get at favorite solutions in a feasible duration of time by producing a primal schedule of status of units at the first step. In the second step the operating units take hourly values by doing Economic Dispatch (ED) on them via a hybrid serial algorithm of Artificial Intelligence (AI) including Particle Swarm Optimization (PSO) and Nelder-Mead (NM) algorithms. In spite of the acceptable solutions obtained by these two stages, the presented method takes another step called the solution modification process (SMP) to reach a more suitable solution. The simulation results over some standard cases of UC problem confirm that this method produces robust solutions and generally gets appropriate near-optimal solutions. (author)

    Full Text Available This paper presents a trustworthy unit commitment study to schedule both Renewable Energy Resources (RERs with conventional power plants to potentially decarbonize the electrical network. The study has employed a system with three IEEE thermal (coal-fired power plants as dispatchable distributed generators, one wind plant, one solar plant as stochastic distributed generators, and Plug-in Electric Vehicles (PEVs which can work either loads or generators based on their charging schedule. This paper investigates the unit commitment scheduling objective to minimize the Combined Economic Emission Dispatch (CEED. To reduce combined emission costs, integrating more renewable energy resources (RER and PEVs, there is an essential need to decarbonize the existing system. Decarbonizing the system means reducing the percentage of CO2 emissions. The uncertain behavior of wind and solar energies causes imbalance penalty costs. PEVs are proposed to overcome the intermittent nature of wind and solar energies. It is important to optimally integrate and schedule stochastic resources including the wind and solar energies, and PEVs charge and discharge processes with dispatched resources; the three IEEE thermal (coal-fired power plants. The Water Cycle Optimization Algorithm (WCOA is an efficient and intelligent meta-heuristic technique employed to solve the economically emission dispatch problem for both scheduling dispatchable and stochastic resources. The goal of this study is to obtain the solution for unit commitment to minimize the combined cost function including CO2 emission costs applying the Water Cycle Optimization Algorithm (WCOA. To validate the WCOA technique, the results are compared with the results obtained from applying the Dynamic Programming (DP algorithm, which is considered as a conventional numerical technique, and with the Genetic Algorithm (GA as a meta-heuristic technique.

    Thermal power plants consist of several generating units with different generating capacities, fuel cost per MWH generated, minimum up/down times, and start-up or shut-down costs. The Unit Commitment (UC) problem in power systems involves determining the start-up and shut-down schedules of thermal generating units to meet forecasted load over a future short term for a period of one to seven days. This paper presented a new approach for the most complex UC problem using agglomerative and divisive hierarchical clustering. Euclidean costs, which are a measure of differences in fuel cost and start-up costs of any two units, were first calculated. Then, depending on the value of Euclidean costs, similar type of units were placed in a cluster. The proposed methodology has 2 individual algorithms. An agglomerative cluster algorithm is used while the load is increasing, and a divisive cluster algorithm is used when the load is decreasing. A search was conducted for an optimal solution for a minimal number of clusters and cluster data points. A standard ten-unit thermal unit power system was used to test and evaluate the performance of the method for a period of 24 hours. The new approach proved to be quite effective and satisfactory. 15 refs., 9 tabs., 5 figs.

    This paper proposes a discrete binary differential evolution (DBDE) approach to solve the unit commitment problem (UCP). The proposed method is enhanced by priority list based on the unit characteristics and heuristic search strategies to handle constraints effectively. The implementation of the proposed method for UCP consists of three stages. Firstly, the DBDE based on priority list is applied for unit scheduling when neglecting the minimum up/down time constraints. Secondly, repairing strategies are used to handle the minimum up/down time constraints and decommit excess spinning reserve units. Finally, heuristic unit substitution search and gray zone modification algorithm are used to improve optimal solution further. Furthermore, the effects of two crucial parameters on performance of the DBDE for solving UCP are studied as well. To verify the advantages of the method, the proposed method is tested and compared to the other methods on the systems with the number of units in the range of 10-100. Numerical results demonstrate that the proposed method is superior to other methods reported in the literature.

    The US Senate consented to the ratification of the Convention on Supplementary Compensation for Nuclear Damage (CSC) on 4 August 2006. The entry into force of the Convention on Supplementary Compensation will substantially change the face of the international nuclear liability regime. The CSC is a free-standing instrument, open to all states. This means that countries can become party to a new global regime providing for liability and compensation for victims of a nuclear incident, without also having to become a contracting party to the Paris Convention or the Vienna Convention. This is certainly a major step forward given that at the present time, over half of the world's reactors in operation or under construction are not covered by any of the international nuclear third party liability conventions. The CSC creates an instrument by which states can ensure that more money will be made available to compensate more victims for a broader range of damage than ever before. The CSC provides for two tiers of compensation. The first tier, fixed at 300 million Special Drawing Rights, is to be provided by the liable operator. This tier is to be distributed on a non-discriminatory basis to victims both inside and outside of the Installation State. If 300 million SDRs are insufficient to compensate all damage, then contracting parties will be required to contribute to the second tier (the international fund). The amount of this second tier is not fixed, but rather will depend on the number of operating nuclear power plants in contracting parties, and is designed to increase as the number of such plants increases

    Ant colony optimization (ACO) is successfully applied in optimization problems. Performance of the basic ACO for small problems with moderate dimension and searching space is satisfactory. As the searching space grows exponentially in the large-scale unit commitment problem, the basic ACO is not applicable for the vast size of pheromone matrix of ACO in practical time and physical computer-memory limit. However, memory-bounded methods prune the least-promising nodes to fit the system in computer memory. Therefore, the authors propose memory-bounded ant colony optimization (MACO) in this paper for the scalable (no restriction for system size) unit commitment problem. This MACO intelligently solves the limitation of computer memory, and does not permit the system to grow beyond a bound on memory. In the memory-bounded ACO implementation, A{sup *} heuristic is introduced to increase local searching ability and probabilistic nearest neighbor method is applied to estimate pheromone intensity for the forgotten value. Finally, the benchmark data sets and existing methods are used to show the effectiveness of the proposed method. (author)

    Penetration of renewable energy resources, such as wind and solar power, into power systems significantly increases the uncertainties on system operation, stability, and reliability in smart grids. In this paper, the nonparametric neural network-based prediction intervals (PIs) are implemented for forecast uncertainty quantification. Instead of a single level PI, wind power forecast uncertainties are represented in a list of PIs. These PIs are then decomposed into quantiles of wind power. A new scenario generation method is proposed to handle wind power forecast uncertainties. For each hour, an empirical cumulative distribution function (ECDF) is fitted to these quantile points. The Monte Carlo simulation method is used to generate scenarios from the ECDF. Then the wind power scenarios are incorporated into a stochastic security-constrained unit commitment (SCUC) model. The heuristic genetic algorithm is utilized to solve the stochastic SCUC problem. Five deterministic and four stochastic case studies incorporated with interval forecasts of wind power are implemented. The results of these cases are presented and discussed together. Generation costs, and the scheduled and real-time economic dispatch reserves of different unit commitment strategies are compared. The experimental results show that the stochastic model is more robust than deterministic ones and, thus, decreases the risk in system operations of smart grids.

    Full Text Available The increasing concern of global climate changes, the promotion of renewable energy sources, primarily wind generation, is a welcome move to reduce the pollutant emissions from conventional power plants. Integration of wind power generation with the existing power network is an emerging research field. This paper presents a meta-heuristic algorithm based approach to determine the feasible dispatch solution for wind integrated thermal power system. The Unit Commitment (UC process aims to identify the best feasible generation scheme of the committed units such that the overall generation cost is reduced, when subjected to a variety of constraints at each time interval. As the UC formulation involves many variables and system and operational constraints, identifying the best solution is still a research task. Nowadays, it is inevitable to include power system reliability issues in operation strategy. The generator failure and malfunction are the prime influencing factor for reliability issues hence they have considered in UC formulation of wind integrated thermal power system. The modern evolutionary algorithm known as Grey Wolf Optimization (GWO algorithm is applied to solve the intended UC problem. The potential of the GWO algorithm is validated by the standard test systems. Besides, the ramp rate limits are also incorporated in the UC formulation. The simulation results reveal that the GWO algorithm has the capability of obtaining economical resolutions with good solution quality.

  1. Modeling and Optimization of the Medium-Term Units Commitment of Thermal Power

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Coal-fired thermal power plants, which represent the largest proportion of China’s electric power system, are very sluggish in responding to power system load demands. Thus, a reasonable and feasible scheme for the medium-term optimal commitment of thermal units (MOCTU can ensure that the generation process runs smoothly and minimizes the start-up and shut-down times of thermal units. In this paper, based on the real-world and practical demands of power dispatch centers in China, a flexible mathematical model for MOCTU that uses equal utilization hours for the installed capacity of all thermal power plants as the optimization goal and that considers the award hours for MOCTU is developed. MOCTU is a unit commitment (UC problem with characteristics of large-scale, high dimensions and nonlinearity. For optimization, an improved progressive optimality algorithm (IPOA offering the advantages of POA is adopted to overcome the drawback of POA of easily falling into the local optima. In the optimization process, strategies of system operating capacity equalization and single station operating peak combination are introduced to move the target solution from the boundary constraints along the target isopleths into the feasible solution’s interior to guarantee the global optima. The results of a case study consisting of nine thermal power plants with 27 units show that the presented algorithm can obtain an optimal solution and is competent in solving the MOCTU with high efficiency and accuracy as well as that the developed simulation model can be applied to practical engineering needs.

    2014-01-01

    With increasing wind farm integrations, unit commitment (UC) is more difficult to solve because of the intermittent and fluctuation nature of wind power. In this paper, scenario generation and reduction technique is applied to simulate the impacts of its uncertainty on system operation. And then a model of thermal UC problem with wind power integration (UCW) is established. Combination of quantum-inspired binary gravitational search algorithm (GSA) and scenario analysis method is proposed to solve UCW problem. Meanwhile, heuristic search strategies are used to handle the constraints of thermal unit for each scenario. In addition, a priority list of thermal units based on the weight between average full-load cost and maximal power output is utilized during the optimization process. Moreover, two UC test systems with and without wind power integration are used to verify the feasibility and effectiveness of the proposed method as well as the performance of the algorithm. The results are analyzed in detail, which demonstrate the model and the proposed method is practicable. The comparison with other methods clearly shows that the proposed method has higher efficiency for solving UC problems with and even without wind farm integration. - Highlights: • Impact of wind fluctuation on unit commitment problem (UCW) is investigated. • Quantum-inspired gravitational search algorithm (QBGSA) is used to optimize UC. • A new method combines QBGSA with scenario analysis is proposed to solve UCW. • Heuristic search strategies are applied to handle the constraints of the UCW. • The results verify the proposed method is feasible and efficient for handling UCW

    2015-01-01

    Highlights: • A short-term structured investment planning model has been developed. • Unit commitment problem is incorporated into the long-term planning horizon. • Inherent intermittency of renewables is modelled in a comprehensive way. • The impact of CO_2 emission pricing in long-term investment decisions is quantified. • The evolution of system’s marginal price is evaluated for all the planning horizon. - Abstract: This work presents a generic mixed integer linear programming (MILP) model that integrates the unit commitment problem (UCP), i.e., daily energy planning with the long-term generation expansion planning (GEP) framework. Typical daily constraints at an hourly level such as start-up and shut-down related decisions (start-up type, minimum up and down time, synchronization, soak and desynchronization time constraints), ramping limits, system reserve requirements are combined with representative yearly constraints such as power capacity additions, power generation bounds of each unit, peak reserve requirements, and energy policy issues (renewables penetration limits, CO_2 emissions cap and pricing). For modelling purposes, a representative day (24 h) of each month over a number of years has been employed in order to determine the optimal capacity additions, electricity market clearing prices, and daily operational planning of the studied power system. The model has been tested on an illustrative case study of the Greek power system. Our approach aims to provide useful insight into strategic and challenging decisions to be determined by investors and/or policy makers at a national and/or regional level by providing the optimal energy roadmap under real operating and design constraints.

    Commitment, competencies and skills of people working in the health sector can significantly impact the performance and its reform process. In this study we attempted to analyse the commitment of state health officials and its implications for human resource practices in Gujarat. A self-administered questionnaire was used to measure commitment and its relationship with human resource (HR) variables. Employee's organizational commitment (OC) and professional commitment (PC) were measured using OC and PC scale. Fifty five medical officers from Gujarat participated in the study. Professional commitment of doctors (3.21 to 4.01) was found to be higher than their commitment to the organization (3.01 to 3.61). Doctors did not perceive greater fairness in the system on promotion (on the scale of 5, score: 2.55) and were of the view that the system still followed seniority based promotion (score: 3.42). Medical officers were upset about low autonomy in the department with regard to reward and recognition, accounting procedure, prioritization and synchronization of health programme and other administrative activities. Our study provided some support for positive effects of progressive HR practices on OC, specifically on affective and normative OC. Following initiatives were identified to foster a development climate among the health officials: providing opportunities for training, professional competency development, developing healthy relationship between superiors and subordinates, providing useful performance feedback, and recognising and rewarding performance. For reform process in the health sector to succeed, there is a need to promote high involvement of medical officers. There is a need to invest in developing leadership quality, supervision skills and developing autonomy in its public health institutions.

    The paper deals with State nuclear initiatives regarding the role of nuclear power in the energy future of the United States. The question of whether and under what circumstances nuclear facilities should be used to generate electricity was put to the popular vote in several States in 1976. Some general principles of Federal-State relations are discussed with specific reference to nuclear regulations. The initiative mechanism itself is described as well as its legal form and background. The parallel developments in the State and Federal legislative consideration of nuclear issues is reviewed and the suggested reasons for the defeat of the proposals in the seven States concerned are discussed. Finally, the author draws some conclusions on the effects of the 1976 initiatives on future decision-making in the US on energy policy in general and nuclear power in particular. (NEA) [fr

    Full Text Available Solving the Unit Commitment problem (UCP optimizes the combination of production units operations and determines the appropriate operational scheduling of each production units to satisfy the expected consumption which varies from one day to one month. Besides, each production unit is conducted to constraints that render this problem complex, combinatorial and nonlinear. In this paper, we proposed a new strategy based on the combination three optimization methods: Tabu search, Particle swarm optimization and Lagrangian relaxation methods in order to develop a proper unit commitment scheduling of the production units while reducing the production cost during a definite period. The proposed strategy has been implemented on a the IEEE 9 bus test system containing 3 production unit and the results were promising compared to strategies based on meta-heuristic and deterministic methods.

    Sun, Ninghong

    2013-01-01

    The German Federal Government published its energy concept in September 2010 with a description of the road into the era of renewable energies. Therefore, the future renewable energy installed in Germany is expected to consist mostly of wind and solar, which are subject to intermittency of supply and significant fluctuations. The growing portion of energy generation by fluctuating sources is turning to a big challenge for the power plant unit commitment and the investment decisions as well. In this thesis, a fundamental electricity market model with combined modeling of these two aspects is developed. This model is subsequently applied to the German electricity market to investigate what kind of power plant investments are indispensable, considering the steadily increasing portion of energy generation from fluctuating sources, to ensure a reliable energy supply in a cost-effective way in the future. In addition, current energy policy in Germany regarding the use of renewable energy and nuclear energy is analyzed.

  12. Improving Deterministic Reserve Requirements for Security Constrained Unit Commitment and Scheduling Problems in Power Systems

    Science.gov (United States)

    Wang, Fengyu

    Traditional deterministic reserve requirements rely on ad-hoc, rule of thumb methods to determine adequate reserve in order to ensure a reliable unit commitment. Since congestion and uncertainties exist in the system, both the quantity and the location of reserves are essential to ensure system reliability and market efficiency. The modeling of operating reserves in the existing deterministic reserve requirements acquire the operating reserves on a zonal basis and do not fully capture the impact of congestion. The purpose of a reserve zone is to ensure that operating reserves are spread across the network. Operating reserves are shared inside each reserve zone, but intra-zonal congestion may block the deliverability of operating reserves within a zone. Thus, improving reserve policies such as reserve zones may improve the location and deliverability of reserve. As more non-dispatchable renewable resources are integrated into the grid, it will become increasingly difficult to predict the transfer capabilities and the network congestion. At the same time, renewable resources require operators to acquire more operating reserves. With existing deterministic reserve requirements unable to ensure optimal reserve locations, the importance of reserve location and reserve deliverability will increase. While stochastic programming can be used to determine reserve by explicitly modelling uncertainties, there are still scalability as well as pricing issues. Therefore, new methods to improve existing deterministic reserve requirements are desired. One key barrier of improving existing deterministic reserve requirements is its potential market impacts. A metric, quality of service, is proposed in this thesis to evaluate the price signal and market impacts of proposed hourly reserve zones. Three main goals of this thesis are: 1) to develop a theoretical and mathematical model to better locate reserve while maintaining the deterministic unit commitment and economic dispatch

  13. A Three-Stage Birandom Program for Unit Commitment with Wind Power Uncertainty

    Directory of Open Access Journals (Sweden)

    Na Zhang

    2014-01-01

    Full Text Available The integration of large-scale wind power adds a significant uncertainty to power system planning and operating. The wind forecast error is decreased with the forecast horizon, particularly when it is from one day to several hours ahead. Integrating intraday unit commitment (UC adjustment process based on updated ultra-short term wind forecast information is one way to improve the dispatching results. A novel three-stage UC decision method, in which the day-ahead UC decisions are determined in the first stage, the intraday UC adjustment decisions of subfast start units are determined in the second stage, and the UC decisions of fast-start units and dispatching decisions are determined in the third stage is presented. Accordingly, a three-stage birandom UC model is presented, in which the intraday hours-ahead forecasted wind power is formulated as a birandom variable, and the intraday UC adjustment event is formulated as a birandom event. The equilibrium chance constraint is employed to ensure the reliability requirement. A birandom simulation based hybrid genetic algorithm is designed to solve the proposed model. Some computational results indicate that the proposed model provides UC decisions with lower expected total costs.

    2016-10-01

    Full Text Available In this paper, the uncertainty of wind, solar and load; smart charging and discharging of plug-in hybrid electric vehicles (PHEVs to and from various energy sources; and the coordination of wind, solar power, PHEVs and cost-emission are considered in the smart grid unit commitment (UC. First, a multi-scenario simulation is used in which a set of valid scenarios is considered for the uncertainties of wind and solar energy sources and load. Then the UC problem for the set of scenarios is decomposed into the optimization of interactive agents by multi-agent technology. Agents’ action is represented by a genetic algorithm with adaptive crossover and mutation operators. The adaptive co-evolution of agents is reached by adaptive cooperative multipliers. Finally, simulation is implemented on an example of a power system containing thermal units, a wind farm, solar power plants and PHEVs. The results show the effectiveness of the proposed method. Thermal units, wind, solar power and PHEVs are mutually complementarily by the adaptive cooperative mechanism. The adaptive multipliers’ updating strategy can save more computational time and further improve the efficiency.

  15. Effect of the accuracy of price forecasting on profit in a Price Based Unit Commitment

    2010-01-01

    This paper discusses and quantifies the so-called loss of profit (i.e., the sub-optimality of profit) that can be expected in a Price Based Unit Commitment (PBUC), when incorrect price forecasts are used. For this purpose, a PBUC model has been developed and utilized, using Mixed Integer Linear Programming (MILP). Simulations are used to determine the relationship between the Mean Absolute Percentage Error (MAPE) of a certain price forecast and the loss of profit, for four different types of power plants. A Combined Cycle (CC) power plant and a pumped storage unit show highest sensitivity to incorrect forecasts. A price forecast with a MAPE of 15%, on average, yields 13.8% and 12.1% profit loss, respectively. A classic thermal power plant (coal fired) and cascade hydro unit are less affected by incorrect forecasts, with only 2.4% and 2.0% profit loss, respectively, at the same price forecast MAPE. This paper further demonstrates that if price forecasts show an average bias (upward or downward), using the MAPE as measure of the price forecast might not be sufficient to quantify profit loss properly. Profit loss in this case has been determined as a function of both shift and MAPE of the price forecast. (author)

    2014-01-01

    Full Text Available Due to the continuous increase of the population and the perpetual progress of industry, the energy management presents nowadays a relevant topic that concerns researchers in electrical engineering. Indeed, in order to establish a good exploitation of the electrical grid, it is necessary to solve technical and economic problems. This can only be done through the resolution of the Unit Commitment Problem. Unit Commitment Problem allows optimizing the combination of the production units’ states and determining their production planning, in order to satisfy the expected consumption with minimal cost during a specified period which varies usually from 24 hours to one week. However, each production unit has some constraints that make this problem complex, combinatorial, and nonlinear. This paper presents a comparative study between a strategy based on hybrid gradient-genetic algorithm method and two strategies based on metaheuristic methods, fuzzy logic, and genetic algorithm, in order to predict the combinations and the unit commitment scheduling of each production unit in one side and to minimize the total production cost in the other side. To test the performance of the optimization proposed strategies, strategies have been applied to the IEEE electrical network 14 busses and the obtained results are very promising.

  10. Stochastic Unit Commitment Based on Multi-Scenario Tree Method Considering Uncertainty

    Directory of Open Access Journals (Sweden)

    Kyu-Hyung Jo

    2018-03-01

    Full Text Available With the increasing penetration of renewable energy, it is difficult to schedule unit commitment (UC in a power system because of the uncertainty associated with various factors. In this paper, a new solution procedure based on a multi-scenario tree method (MSTM is presented and applied to the proposed stochastic UC problem. In this process, the initial input data of load and wind power are modeled as different levels using the mean absolute percentage error (MAPE. The load and wind scenarios are generated using Monte Carlo simulation (MCS that considers forecasting errors. These multiple scenarios are applied in the MSTM for solving the stochastic UC problem, including not only the load and wind power uncertainties, but also sudden outages of the thermal unit. When the UC problem has been formulated, the simulation is conducted for 24-h period by using the short-term UC model, and the operating costs and additional reserve requirements are thus obtained. The effectiveness of the proposed solution approach is demonstrated through a case study based on a modified IEEE-118 bus test system.

    This article develops a linear programming cost minimisation model for the high level system design and corresponding unit commitment of generators and storage within a microgrid; a set of energy resources working co-operatively to create a cost effective, reliable and environmentally friendly energy provision system. Previous work in this area is used as a basis for formulation of a new approach to this problem, with particular emphasis on why a microgrid is different to centralised generation or other grid-connected decentralised energy resources. Specifically, the model explicitly defines the amount of time that the microgrid would be expected to operate autonomously, and restricts flow of heat between microgrid participants to defined cases. The model developed is applied to a set of United Kingdom commercial load profiles, under best current estimates of energy prices and technology capital costs, to determine investment attractiveness of the microgrid. Sensitivity analysis of results to variations in energy prices is performed. The results broadly indicate that a microgrid can offer an economic proposition, although it is necessarily slightly more expensive than regular grid-connected decentralised generation. The analysis results have raised important questions regarding a fair method for settlement between microgrid participants, and game theory has been identified as a suitable tool to analyse aspects of this situation.

  13. A Comparative Study of Three Different Mathematical Methods for Solving the Unit Commitment Problem

    Directory of Open Access Journals (Sweden)

    Mehmet Kurban

    2009-01-01

    Full Text Available The unit commitment (UC problem which is an important subject in power system engineering is solved by using Lagragian relaxation (LR, penalty function (PF, and augmented Lagrangian penalty function (ALPF methods due to their higher solution quality and faster computational time than metaheuristic approaches. This problem is considered to be a nonlinear programming-(NP- hard problem because it is nonlinear, mixed-integer, and nonconvex. These three methods used for solving the problem are based on dual optimization techniques. ALPF method which combines the algorithmic aspects of both LR and PF methods is firstly used for solving the UC problem. These methods are compared to each other based on feasible schedule for each stage, feasible cost, dual cost, duality gap, duration time, and number of iterations. The numerical results show that the ALPF method gives the best duality gap, feasible and dual cost instead of worse duration time and the number of iterations. The four-unit Tuncbilek thermal plant which is located in Kutahya region in Turkey is chosen as a test system in this study. The programs used for all the analyses are coded and implemented using general algebraic modeling system (GAMS.

    This paper presents a smart house-based power system for thermal unit commitment programme. The proposed power system consists of smart houses, renewable energy plants and conventional thermal units. The transmission constraints are considered for the proposed system. The generated power of the large capacity renewable energy plant leads to the violated transmission constraints in the thermal unit commitment programme, therefore, the transmission constraint should be considered. This paper focuses on the optimal operation of the thermal units incorporated with controllable loads such as Electrical Vehicle and Heat Pump water heater of the smart houses. The proposed method is compared with the power flow in thermal units operation without controllable loads and the optimal operation without the transmission constraints. Simulation results show the validation of the proposed method.

    2007-01-01

    Using data from the nationally representative National Health and Social Life Survey, this study queried the correlates of masturbation in the United States in 1992. Among those aged 18-60, 38% (CI, 35-41) of women and 61% (CI, 57-65) of men reported any masturbation over the preceding year. The system of factors underlying masturbation was similar for both genders, consistent with a convergence in gender patterns of sexual expression in the United States. Among both women and men, masturbation responded to a stable sexualized personality pattern, catalyzed by early-life factors and manifested in current sexual traits. Strikingly, the masturbation-partnered sex linkage, often conceptualized either as compensating for unsatisfying sex or complementing a satisfactory sex life, appeared to be bimodal for both genders. For some, masturbation complemented an active and pleasurable sex life, while among others, it compensated for a lack of partnered sex or satisfaction in sex.

    The concept of a United States National Seismograph Network (USNSN) dates back nearly 30 years. The idea was revived several times over the decades. but never funded. For, example, a national network was proposed and discussed at great length in the so called Bolt Report (U. S. Earthquake Observatories: Recommendations for a New National Network, National Academy Press, Washington, D.C., 1980, 122 pp). From the beginning, a national network was viewed as augmenting and complementing the relatively dense, predominantly short-period vertical coverage of selected areas provided by the Regional Seismograph Networks (RSN's) with a sparse, well-distributed network of three-component, observatory quality, permanent stations. The opportunity finally to begin developing a national network arose in 1986 with discussions between the US Geological Survey (USGS) and the Nuclear Regulatory Commission (NRC). Under the agreement signed in 1987, the NRC has provided $5 M in new funding for capital equipment (over the period 1987-1992) and the USGS has provided personnel and facilities to develop. deploy, and operate the network. Because the NRC funding was earmarked for the eastern United States, new USNSN station deployments are mostly east of 105 degree W longitude while the network in the western United States is mostly made up of cooperating stations (stations meeting USNSN design goals, but deployed and operated by other institutions which provide a logical extension to the USNSN)

    Many discrete optimization problems may be solved much easier, if the solution space can be restricted in a convenient way. For a given specific problem, the restriction techniques can be helpful if an available optimization solver, perceived as a black box, is capable of solving quickly only reduced subproblems of a limited size. For the family of hard unit-commitment problems we investigate a hierarchical search algorithm, which is based on decomposition of the problem into two subproblems. The upper-level subproblem is a relatively small decision 'kernel' of the problem that can be solved approximately by a search algorithm. We define an appropriate restricted decision space for this subproblem. The lower-level subproblem is an appropriate restriction of the original problem that can be solved efficiently by a dedicated solver. Our approach was analyzed on a set of historical data from the Polish electrical balancing market and the best known solutions were improved by the average of about 2-5%

    To meet the increasingly high requirement of smart grid operations, considering AC power flow constraints in the NCUC (network-constrained unit commitment) is of great significance in terms of both security and economy. This paper proposes a decomposition method to solve NCUC with AC power flow constraints. With conic approximations of the AC power flow equations, the master problem is formulated as a MISOCP (mixed integer second-order cone programming) model. The key advantage of this model is that the active power and reactive power are co-optimised, and the transmission losses are considered. With the AC optimal power flow model, the AC feasibility of the UC result of the master problem is checked in subproblems. If infeasibility is detected, feedback constraints are generated based on the sensitivity of bus voltages to a change in the unit reactive power generation. They are then introduced into the master problem in the next iteration until all AC violations are eliminated. A 6-bus system, a modified IEEE 30-bus system and the IEEE 118-bus system are used to validate the performance of the proposed method, which provides a satisfactory solution with approximately 44-fold greater computational efficiency. - Highlights: • A decomposition method is proposed to solve the NCUC with AC power flow constraints • The master problem considers active power, reactive power and transmission losses. • OPF-based subproblems check the AC feasibility using parallel computing techniques. • An effective feedback constraint interacts between the master problem and subproblem. • Computational efficiency is significantly improved with satisfactory accuracy

    Full Text Available In this paper security constraints unit commitment (SCUC in the presence of wind power resources and electrical vehicles to grid is presented. SCUC operation prepare an optimal time table for generation unit commitment in order to maximize security, minimize operation cost and satisfy the constraints of networks and units in a period of time, as one of the most important research interest in power systems. Today, the relationship between power network and energy storage systems is interested for many researchers and network operators. Using Electrical Vehicles (PEVs and wind power for energy production is one of the newest proposed methods for replacing fossil fuels.One of the effective strategies for analyzing of the effects of Vehicle 2 Grid (V2G and wind power in optimal operation of generation is running of SCUC for power systems that are equipped with V2G and wind power resources. In this paper, game theory method is employed for deterministic solution of day-ahead unit commitment with considering security constraints in the simultaneous presence of V2G and wind power units. This problem for two scenarios of grid-controlled mode and consumer-controlled mode in three different days with light, medium and heavy load profiles is analyzed. Simulation results show the effectiveness of the presence of V2G and wind power for decreasing of generation cost and improving operation indices of power systems.

    2018-05-04

    Malaria in humans is caused by intraerythrocytic protozoa of the genus Plasmodium. These parasites are transmitted by the bite of an infective female Anopheles species mosquito. The majority of malaria infections in the United States occur among persons who have traveled to regions with ongoing malaria transmission. However, malaria is occasionally acquired by persons who have not traveled out of the country through exposure to infected blood products, congenital transmission, laboratory exposure, or local mosquitoborne transmission. Malaria surveillance in the United States is conducted to provide information on its occurrence (e.g., temporal, geographic, and demographic), guide prevention and treatment recommendations for travelers and patients, and facilitate transmission control measures if locally acquired cases are identified. This report summarizes confirmed malaria cases in persons with onset of illness in 2015 and summarizes trends in previous years. Malaria cases diagnosed by blood film microscopy, polymerase chain reaction, or rapid diagnostic tests are reported to local and state health departments by health care providers or laboratory staff members. Case investigations are conducted by local and state health departments, and reports are transmitted to CDC through the National Malaria Surveillance System (NMSS), the National Notifiable Diseases Surveillance System (NNDSS), or direct CDC consultations. CDC reference laboratories provide diagnostic assistance and conduct antimalarial drug resistance marker testing on blood samples submitted by health care providers or local or state health departments. This report summarizes data from the integration of all NMSS and NNDSS cases, CDC reference laboratory reports, and CDC clinical consultations. CDC received reports of 1,517 confirmed malaria cases, including one congenital case, with an onset of symptoms in 2015 among persons who received their diagnoses in the United States.

    Highlights: • Suggesting a new UC mixing a probabilistic security and incentive demand response. • Investigating the effects of uncertainty on UC using chance-constraint programming. • Proposing an efficient spinning reserve satisfaction based on a new ED correction. • Presenting a new operational cycles way to convert binary variable to discrete one. - Abstract: We propose a probabilistic unit commitment problem with incentive-based demand response and high level of wind power. Our novel formulation provides an optimal allocation of up/down spinning reserve. A more efficient unit commitment algorithm based on operational cycles is developed. A multi-period elastic residual demand economic model based on the self- and cross-price elasticities and customers’ benefit function is used. In the proposed scheme, the probability of residual demand falling within the up/down spinning reserve imposed by n − 1 security criterion is considered as a stochastic constraint. A chance-constrained method, with a new iterative economic dispatch correction, wind power curtailment, and commitment of cheaper units, is applied to guarantee that the probability of loss of load is lower than a pre-defined risk level. The developed architecture builds upon an improved Jaya algorithm to generate feasible, robust and optimal solutions corresponding to the operational cost. The proposed framework is applied to a small test system with 10 units and also to the IEEE 118-bus system to illustrate its advantages in efficient scheduling of generation in the power systems.

  1. Daily Emotional Labor, Negative Affect State, and Emotional Exhaustion: Cross-Level Moderators of Affective Commitment

    Directory of Open Access Journals (Sweden)

    2018-06-01

    Full Text Available Employees’ emotional-labor strategies, experienced affects, and emotional exhaustion in the workplace may vary over time within individuals, even within the same day. However, previous studies on these relationships have not highlighted their dynamic properties of these relationships. In addition, although the effects of surface and deep acting on emotional exhaustion have been investigated in emotional-labor research, empirical studies on these relationships still report mixed results. Thus, we suggest that moderators may affect the relationship between emotional labor and emotional exhaustion. Also, this study examines the relationship between emotional labor and emotional exhaustion within individuals by repeated measurements, and verifies the mediating effect of a negative affect state. Finally, our study confirms the moderating effects that affective commitment has on the relationship between emotional labor and emotional exhaustion. Data was collected from tellers who had a high degree of interaction with clients at banks based in South Korea. A total of 56 tellers participated in the survey and responded for five working days. A total of 616 data entries were collected from the 56 respondents. We used a hierarchical linear model (HLM to examine our hypothesis. The results showed that surface-acting emotional labor increases emotional exhaustion; furthermore, the relationship between surface acting emotional labor and emotional exhaustion is mediated by a negative affect state within individuals. In addition, this study verified that affective commitment buffers the negative effects that surface acting emotional labor has on emotional exhaustion. These results suggest that emotional labor is a dynamic process within individuals, and that emotional exhaustion caused by emotional labor differs among individuals, and is dependent upon factors such as the individual’s level of affective commitment.

    Over the last decade, advances in technology have made it profitable to extract natural gas from shale, leading to a boom in shale gas development in the United States. Hydraulic fracturing, or fracking, the controversial method for extracting natural gas, offers numerous benefits: relatively cheap energy, enhanced energy security, job creation, tax revenues and decreased dependence on dirty coal. Fracking, however, can also increase greenhouse gas emissions, pollute the air and result in health effects, consume huge quantities of water, and cause earthquakes. While some areas welcome fracking for the economic benefits it brings, other communities are attempting to ban fracking altogether. This article examines the benefits and risks of fracking in the U.S

    ERDA's uranium enrichment program policies governing the manner in which ERDA's enrichment complex is being operated and expanded to meet customer requirements for separative work, research and development activities directed at providing technology alternatives for future enrichment capacity, and establishing the framework for additional domestic uranium enrichment capacity to meet the domestic and foreign nuclear industry's growing demand for enrichment services are considered. The ERDA enrichment complex consists of three gaseous diffusion plants located in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. Today, these plants provide uranium enrichment services for commercial nuclear power generation. These enrichment services are provided under contracts between the Government and the utility customers. ERDA's program involves a major pilot plant cascade, and pursues an advanced isotope separation technique for the late 1980's. That the United States must develop additional domestic uranium enrichment capacity is discussed

The majority of malaria infections in the United States occur among persons who have traveled to regions with ongoing malaria transmission. However, malaria is occasionally acquired by persons who have not traveled out of the country through exposure to infected blood products, congenital transmission, laboratory exposure, or local mosquitoborne transmission. Malaria surveillance in the United States is conducted to identify episodes of local transmission and to guide prevention recommendations for travelers. This report summarizes cases in persons with onset of illness in 2014 and trends during previous years. Malaria cases diagnosed by blood film, polymerase chain reaction, or rapid diagnostic tests are reported to local and state health departments by health care providers or laboratory staff. Case investigations are conducted by local and state health departments, and reports are transmitted to CDC through the National Malaria Surveillance System, National Notifiable Diseases Surveillance System, or direct CDC consultations. CDC conducts antimalarial drug resistance marker testing on blood samples submitted by health care providers or local or state health departments. Data from these reporting systems serve as the basis for this report. CDC received reports of 1,724 confirmed malaria cases, including one congenital case and two cryptic cases, with onset of symptoms in 2014 among persons in the United States. The number of confirmed cases in 2014 is consistent with the number of confirmed cases reported in 2013 (n = 1,741; this number has been updated from a previous publication to account for delayed reporting for persons with symptom onset occurring in late 2013). Plasmodium falciparum, P. vivax, P. ovale, and P. malariae were identified in 66.1%, 13.3%, 5.2%, and 2.7% of cases, respectively

  7. Two-Stage Robust Security-Constrained Unit Commitment with Optimizable Interval of Uncertain Wind Power Output

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Because wind power spillage is barely considered, the existing robust unit commitment cannot accurately analyze the impacts of wind power accommodation on on/off schedules and spinning reserve requirements of conventional generators and cannot consider the network security limits. In this regard, a novel double-level robust security-constrained unit commitment formulation with optimizable interval of uncertain wind power output is firstly proposed in this paper to obtain allowable interval solutions for wind power generation and provide the optimal schedules for conventional generators to cope with the uncertainty in wind power generation. The proposed double-level model is difficult to be solved because of the invalid dual transform in solution process caused by the coupling relation between the discrete and continuous variables. Therefore, a two-stage iterative solution method based on Benders Decomposition is also presented. The proposed double-level model is transformed into a single-level and two-stage robust interval unit commitment model by eliminating the coupling relation, and then this two-stage model can be solved by Benders Decomposition iteratively. Simulation studies on a modified IEEE 26-generator reliability test system connected to a wind farm are conducted to verify the effectiveness and advantages of the proposed model and solution method.

  8. Uranium procurement in the United States of America

    Thomas, D.C.; Krusiewski, S.V.

    1983-01-01

    The United States Department of Energy conducts surveys of US uranium marketing activity. The results of this year's survey compared with last year's survey indicate that delivery commitments of US uranium producers to US uranium users have decreased in the early part of this decade, but have increased in the latter part of the decade. Unfilled uranium requirements are nearly the same through 1986 in both surveys, but in the 1987-1990 period this years's unfilled requirements are lower than those reported last year. Non-US purchase commitments by US utilities are somewhat greater than those reported last year. Non-US purchase commitments by US reactor manufacturers and producers have increased significantly over the past year; about two-thirds of these purchase commitments resulted from the settlement of litigation with non-US suppliers. The attitude of US utilities as to their use of non-US uranium has remained the same over the past year. Although some of the utilities were uncertain about future non-US uranium purchases, many of them indicated that they would possibly purchase non-US uranium. Natural uranium inventories of US reactor manufacturers and utilities have increased over the past year, and now amount to about 3 years of forward coverage. The enriched uranium inventories held by these users have decreased over the past year, and now amount to less than 1 year's forward coverage. (author)

    2015-10-01

    The present study analyzed sex offender civil management (i.e., civil commitment) legal proceedings in New York State and identified factors that predict trial results. Specifically, the current study compared a sample of 38 sex offenders who were released to the community after winning their civil management trials to 183 sex offenders who lost their civil management trials. Additionally, for the 183 sex offenders who lost their civil management trials, the current study compared 146 offenders who were ordered to inpatient civil commitment to 37 offenders who were deemed fit for civil management in the community. Results of the analyses indicated that sexual criminality, sexual deviance, and criminality involving child victims increased the likelihood of offenders both losing their civil management trial and being found to be in need of inpatient care, while the presence of variables associated with nonsexual criminality increased the likelihood of offenders both winning their civil management trials and being deemed fit for management in the community. The findings of this study provide guidance for psychiatric examiners who testify in civil management legal proceedings, as well as for legal professionals specializing in civil management cases.

    We demonstrate experimentally the feasibility of a two-state quantum bit commitment protocol, which is both concealing and partially binding, assuming technological limitations. The security of this protocol is based on the lack of long-term stable quantum memories. We use a polarization-encoding scheme and optical fiber as a quantum channel. The measurement probability for the commitment is obtained and the optimal cheating strategy demonstrated. The average success rates for an honest player in the case where the measurements are performed using equal bases are 93.4%, when the rectilinear basis is measured, and 96.7%, when the diagonal basis is measured. The rates for the case when the measurements are performed in different bases are 52.9%, when the rectilinear basis is measured, and 55.4% when the diagonal basis is measured. The average success rates for the optimal cheating strategy are 80% and 73.8%, which are way below the success rates of an honest player. Using a strict numerical validity criterion, we show that, for these experimental values, the protocol is secure. (paper)

    In 2005, the United States had 297 million inhabitants (the 3. most populous country in the world) and a land area of 9.4 million km 2 (17 times larger than France). With a GDP of 10,996 billion dollars (under the economic conditions of the year 2000), the U.S. is the largest economic power in the world. It is also the largest consumer of energy, with primary energy consumption of 2,329 million metric tons, meaning that 25% of the world's energy is consumed by just 4% of its population. Although it has large domestic energy supplies, the U.S. is very far from achieving energy self-sufficiency. A decline of nearly 50% in oil production over a period of more than 30 years and the simultaneous stagnation of gas production have further weakened the U.S. energy balance. On a more general level, the increasing depletion of hydrocarbon resources (gas and oil), the concentration of the world's main resources in geo-politically unstable areas and the forecasted increase in the consumption and price of hydrocarbons, especially since 2005, mean that energy independence and supply security have become 2 of the top priorities of U.S. commercial and international policy. In 2007, the U.S. accounted for 22% of global CO 2 emissions, equaling those of China. In relation to population, the U.S. emits 8 metric tons/inhabitant compared to a world average of 4.2 metric tons/inhabitant. Although global warming is seen as a reality by the American public, it has only recently become a major argument in favor of a nuclear energy revival in the U.S. The context is, however, changing significantly. This is evidenced by America's adoption, in recent years, of measures to reduce greenhouse gases, particularly through the development of new, more environmentally friendly technologies. Since 2001, nearly 23 billion dollars in public funds have been devoted to climate research and the development of clean energy sources, notably renewable energies such as wind and solar, but also hydrogen and

    Wermund, E.G.

    1990-01-01

    In several Texas environmental laws, the Bureau of Economic Geology is designated as a planning participant and review agency in the process of fulfilling environmental laws. Two examples are legislation on reclamation of surface mines and regulation of processing low level radioactive wastes. Also, the Bureau is the principal geological reviewer of all Environmental Assessments and Environmental Impact Statements which the Office of the Governor circulates for state review on all major developmental activities in Texas. The BEG continues its strong interest in environmental geology. In February 1988, it recommitted its Land Resources Laboratory, initiated in 1974, toward fulfilling needs of state, county, and city governments for consultation and research on environmental geologic problems. An editorial from another state geological survey would resemble the about description of texas work in environmental geology. State geological surveys have led federal agencies into many developments of environmental geology, complemented federal efforts in their evolution, and continued a strong commitment to the maintenance of a quality environment through innovative geologic studies

    With the rapid development and deployment of voltage source converter (VSC) based HVDC, the traditional power system is evolving to the hybrid AC-DC grid. New optimization methods are urgently needed for these hybrid AC-DC power systems. In this paper, mixed-integer second order cone programming...... (MISOCP) for the hybrid AC-DC power systems is proposed. The second order cone (SOC) relaxation is adopted to transform the AC and DC power flow constraints to MISOCP. Several IEEE test systems are used to validate the proposed MISCOP formulation of the optimal power flow (OPF) and unit commitment (UC...

    Highlights: • A new UCsRP problem with flexible integrations is established. • A novel multi-zone sampling method is proposed for scenarios generation. • A meta-heuristic solving tool is introduced for solving the UCsRP problem. • A comprehensive study is conducted considering multiple weathers and seasons. • The economic effects of various scenarios are evaluated and compared. - Abstract: Significant penetration of renewable generations (RGs) and mass roll-out of plug-in electric vehicles (PEVs) will pay a vital role in delivering the low carbon energy future and low emissions of greenhouse gas (GHG) that are responsible for the global climate change. However, it is of considerable difficulties to precisely forecast the undispatchable and intermittent wind and solar power generations. The uncoordinated charging of PEVs imposes further challenges on the unit commitment in modern grid operations. In this paper, all these factors are comprehensively investigated for the first time within a novel hybrid unit commitment framework, namely UCsRP, which considers a wide range of scenarios in renewable generations and demand side management of dispatchable PEVs load. UCsRP is however an extremely challenging optimisation problem not only due to the large scale, mixed integer and nonlinearity, but also due to the double uncertainties relating to the renewable generations and PEV charging and discharging. In this paper, a meta-heuristic solving tool is introduced for solving the UCsRP problem. A key to improve the reliability of the unit commitment is to generate a range of scenarios based on multiple distributions of renewable generations under different prediction errors and extreme predicted value conditions. This is achieved by introducing a novel multi-zone sampling method. A comprehensive study considering four different cases of unit commitment problems with various weather and season scenarios using real power system data are conducted and solved, and smart

    IMPORTANCE Interpersonal violence, which includes child abuse and neglect, youth violence, intimate partner violence, sexual violence, and elder abuse, affects millions of US residents each year. However, surveillance systems, programs, and policies to address violence often lack broad, cross-sector collaboration, and there is limited awareness of effective strategies to prevent violence. OBJECTIVES To describe the burden of interpersonal violence in the United States, explore challenges to violence prevention efforts and to identify prevention opportunities. DATA SOURCES We reviewed data from health and law enforcement surveillance systems including the National Vital Statistics System, the Federal Bureau of Investigation’s Uniform Crime Reports, the US Justice Department’s National Crime Victimization Survey, the National Survey of Children’s Exposure to Violence, the National Child Abuse and Neglect Data System, the National Intimate Partner and Sexual Violence Survey, the Youth Risk Behavior Surveillance System, and the National Electronic Injury Surveillance System—All Injury Program. RESULTS Homicide rates have decreased from a peak of 10.7 per 100 000 persons in 1980 to 5.1 per 100 000 in 2013. Aggravated assault rates have decreased from a peak of 442 per 100 000 in 1992 to 242 per 100 000 in 2012. Nevertheless, annually, there are more than 16 000 homicides and 1.6 million nonfatal assault injuries requiring treatment in emergency departments. More than 12 million adults experience intimate partner violence annually and more than 10 million children younger than 18 years experience some form of maltreatment from a caregiver, ranging from neglect to sexual abuse, but only a small percentage of these violent incidents are reported to law enforcement, health care clinicians, or child protective agencies. Moreover, exposure to violence increases vulnerability to a broad range of mental and physical health problems over the life course; for example

  13. A Multi-Objective Unit Commitment Model for Setting Carbon Tax to Reduce CO2 Emission: Thailand's Electricity Generation Case

    Directory of Open Access Journals (Sweden)

    Nuchjarin Intalar

    2015-07-01

    Full Text Available Carbon tax policy is a cost-effective instrument for emission reduction. However, setting the carbon tax is one of the challenging task for policy makers as it will lead to higher price of emission-intensive sources especially the utility price. In a large-scale power generation system, minimizing the operational cost and the environmental impact are conflicting objectives and it is difficult to find the compromise solution. This paper proposes a methodology of finding a feasible carbon tax rate on strategic level using the operational unit commitment model. We present a multi-objective mixed integer linear programming model to solve the unit commitment problem and consider the environmental impacts. The methodology of analyzing of the effect of carbon tax rates on the power generation, operating cost, and CO2 emission is also provided. The trade-off relationship between total operating cost and total CO2 emission is presented in the Pareto-optimal curve to analyze the feasible carbon tax rate that is influencing on electricity operating cost. The significant outcome of this paper is a modeling framework for the policy makers to determine the possible carbon tax that can be imposed on the electricity generation.

  1. Nuclear development in the United States

    International Nuclear Information System (INIS)

    Brewer, S.

    1983-01-01

    The history of the nuclear development in the United States has been one of international cooperation relations so far. The United States is to offer the technical information on atomic energy utilization to foreign countries in exchange for the guarantee that they never attempt to have or develop nuclear weapons. Actually, the United States has supplied the technologies on nuclear fuel cycle and other related fields to enable other countries to achieve economical and social progress. The Department of Energy clarified the public promise of the United States regarding the idea of international energy community. The ratio of nuclear power generation to total electric power supply in the United States exceeded 12%, and will exceed 20% by 1990. Since 1978, new nuclear power station has not been ordered, and some of the contracted power stations were canceled. The atomic energy industry in the United States prospered at the beginning of 1970s, but lost the spirit now, mainly due to the institutional problems rather than the technical ones. As the policy of the government to eliminate the obstacles, the improvement of the procedure for the permission and approval, the establishment of waste disposal capability, the verification of fast breeder reactor technology and the promotion of commercial fuel reprocessing were proposed. The re-establishment of the United States as the reliable supplier of atomic energy service is the final aim. (Kako, I.)

  2. Multilevel Analysis of Employee Satisfaction on Commitment to Organizational Culture: Case Study of Chinese State-Owned Enterprises

    Directory of Open Access Journals (Sweden)

    Fangtao Liu

    2017-11-01

    Full Text Available This study analyzes the effects of employee satisfaction and demographic indicators on employee commitment to organizational culture at the enterprise level. With data from a survey of 3029 employees from 27 state-owned enterprises (SOEs, a hierarchical linear model (HLM is used to identify the influencing factors of employee commitment to organizational culture at the enterprise level. An empirical study indicates that apart from the factors of employee satisfaction and demographic background, four contextual variables of enterprises, namely, comprehensive management, energy intensity, cost-income ratio, and capacity-load ratio, also influence commitment to organizational culture levels. Results show that applying HLM can substantially improve the explanatory power of employee satisfaction factors on commitment to organizational culture using nested enterprise contextual variables. Although measurement scales and satisfaction models have been proposed over the years, only a few studies have addressed the particular nature inherent in Chinese SOEs. HLM, which accounts for the nested data structure and determines the effects of employee satisfaction factors on commitment to organizational culture without bias, is developed in this study. Through an insider view based on empirical work, this research can improve the ability of senior managers to understand the culture and dynamics of organizations, to deliver strong leadership, and to enhance corporate internal management.

    A total of 10,000 U.S. households in 25 standard metropolitan statistical areas and 25 counties were included in the United States. More than 8,200 households granted an interview. Nine of every ten households in the United States used some types of pesticide in their house, garden, or yard. Households in the southeastern United States used the most pesticides. Although more than 500 different pesticide formulations were used by the sampled households, 15 pesticides accounted for 65.5% of all pesticides reported in this study. Thirteen of these 15 pesticides were insecticides, one was a herbicide, and one was a rodenticide.

  4. Canada's national report on climate change: Actions to meet commitments under the United Nations framework convention on climate change

    International Nuclear Information System (INIS)

    1994-01-01

    Under the United Nations Framework Convention on Climate Change, countries must adopt measures to mitigate climate change, adapt to its possible effects, increase public awareness and scientific understanding of climate change and possible responses, and work together in all of these areas. A review is provided of action being currently taken by Canadian governments, non-governmental organizations, communities, and the private sector to meet domestic and international climate change commitments. Projections indicate that climate change could result in significant changes to many of Canada's natural ecosystems, with equally significant economic and social consequences. Canadian demand for energy is the chief cause of Canada's man-made emissions of greenhouse gases. As a first step in meeting its commitment, Canada is developing and implementing measures to limit greenhouse gas emissions, mainly in the area of energy efficiency, energy conservation, and switching to energy sources that are less carbon-intensive. Progress in limiting such emissions will be assessed via emissions inventories, examination of climatic change indicators, forecasting future energy-related emissions of the three primary greenhouse gases, and use of case studies to assess the effectiveness of emissions control measures. Other components of Canadian activities include increasing public awareness of climate change, sponsoring research on the subject, reviewing environmental policies, and international cooperation. 59 refs., 36 figs., 23 tabs

  5. The distribution of committed dose equivalents to workers exposed to tritium in the luminising industry in the United Kingdom

    International Nuclear Information System (INIS)

    Hipkin, J.

    1977-01-01

    In the United Kingdom tritium has become almost the only radionuclide that is used in luminising. Two distinct methods of luminising are used, one involving the use of tritium gas and the other involving the use of tritium activated luminous paint. All major luminisers have voluntarily taken part in urine monitoring programmes. The analyses have been carried out by the National Radiological Protection Board and estimates of committed dose equivalent have been made from the results. The work presented is an analysis of the committed dose equivalents received by all the individuals monitored in the years 1974, 1975 and 1976. It is shown that doses follow, in general, a lognormal distribution modified only at the high dose end by what must be described as dose management. Further evidence for dose management is seen when the pattern of dose versus time are analysed for selected individuals. It is shown that the maximum permissible dose as recommended by the International Commission on Radiological Protection, is only rarely exceeded. It is also shown that there is a substantial difference in the degree of exposure between workers involved in gaseous tritium luminising and workers using paint luminising. A comparison is made between exposure in gaseous tritium luminising and exposure in another common use of gaseous tritium, ie. the filling of electronic devices with tritium gas. It is shown that exposure is very much less in the electronic device work

    Energy Technology Data Exchange (ETDEWEB)

    Ela, E.; O' Malley, M.

    2012-06-01

    Variable renewable generation resources are increasing their penetration on electric power grids. These resources have weather-driven fuel sources that vary on different time scales and are difficult to predict in advance. These characteristics create challenges for system operators managing the load balance on different timescales. Research is looking into new operational techniques and strategies that show great promise on facilitating greater integration of variable resources. Stochastic Security-Constrained Unit Commitment models are one strategy that has been discussed in literature and shows great benefit. However, it is rarely used outside the research community due to its computational limits and difficulties integrating with electricity markets. This paper discusses how it can be integrated into day-ahead energy markets and especially on what pricing schemes should be used to ensure an efficient and fair market.

  4. Regulatory practices - United States example

    International Nuclear Information System (INIS)

    Shapar, M.

    1976-01-01

    In 1954, the Atomic Energy Act of 1946 was revised to do away with the federal state monopoly in this field and to enable private industry to develop nuclear power. This evolution led the federal authorities to give the Atomic Energy Commission the powers to control the design, licensing and operation of nuclear reactors. These powers were constantly strengthened and are now exercised by the Nuclear Regulatory Commission (NRC). Since its creation in 1975, the Commission has amended the regulations on licensing of nuclear reactors in the light of experience acquired so as to shorten the duration of this procedure. These amendments concern the standardization of nuclear power plants, limited work authorizations, the methods for issuing licenses. The objective of the Commission aim to make the licensing procedure for nuclear power plants simpler and more efficient and hence, less costly, while ensuring that a very high level for safety standards and environmental protection is maintained.

    The united states are the third world producer of oil which accounts for 440% of world production and 20 million barrels/day of which 60% are imported. That dependence on imports is likely to increase in the next decades. Such supplies and their security are therefore a fundamental factor of the United States foreign policy in combination with their political, economic and strategic objectives in a world both unsure and dangerous

    2016-05-01

    Energy storage systems (ESSs) have experienced a very rapid growth in recent years and are expected to be a promising tool in order to improving power system reliability and being economically efficient. The ESSs possess many potential benefits in various areas in the electric power systems. One of the main benefits of an ESS, especially a bulk unit, relies on smoothing the load pattern by decreasing on-peak and increasing off-peak loads, known as load leveling. These devices require new methods and tools in order to model and optimize their effects in the power system studies. In this respect, this paper will model bulk ESSs based on the several technical characteristics, introduce the proposed model in the thermal unit commitment (UC) problem, and analyze it with respect to the various sensitive parameters. The technical limitations of the thermal units and transmission network constraints are also considered in the model. The proposed model is a Mixed Integer Linear Programming (MILP) which can be easily solved by strong commercial solvers (for instance CPLEX) and it is appropriate to be used in the practical large scale networks. The results of implementing the proposed model on a test system reveal that proper load leveling through optimum storage scheduling leads to considerable operation cost reduction with respect to the storage system characteristics.

    2011-11-09

    A flow chart depicting energy flow in the transportation sector of the United States economy in 2005 has been constructed from publicly available data and estimates of national energy use patterns. Approximately 31,000 trillion British Thermal Units (trBTUs) of energy were used throughout the United States in transportation activities. Vehicles used in these activities include automobiles, motorcycles, trucks, buses, airplanes, rail, and ships. The transportation sector is powered primarily by petroleum-derived fuels (gasoline, diesel and jet fuel). Biomass-derived fuels, electricity and natural gas-derived fuels are also used. The flow patterns represent a comprehensive systems view of energy used within the transportation sector.

    The U.S. Geological Survey (USGS) has been collecting and interpreting natural-resources data in Nevada for more than 100 years. This long-term commitment enables planners to manage better the resources of a State noted for paradoxes. Although Nevada is one of the most sparsely populated States in the Nation, it has the fastest growing population (fig. 1). Although 90 percent of the land is rural, it is the fourth most urban State. Nevada is the most arid State and relies heavily on water resources. Historically, mining and agriculture have formed the basis of the economy; now tourism and urban development also have become important. The USGS works with more than 40 local, State, and other Federal agencies in Nevada to provide natural-resources information for immediate and long-term decisions.Subjects included in this fact sheet:Low-Level Radioactive-Waste DisposalMining and Water in the Humboldt BasinAquifer Systems in the Great BasinWater Allocation in Truckee and Carson BasinsNational Water-Quality Assessment ProgramMinerals Assessment for Land ManagementIrrigation DrainageGround-Water Movement at Nevada Test SiteOil and Gas ResourcesNational Mapping ProgramDigital Mapping and Aerial PhotographyCollection of Hydrologlc DataGeologic MappingEarthquake HazardsAssessing Mineral Resources of the SubsurfaceEarth Observation DataCooperative Programs

    Purpose: About half of all cancer patients in the United States receive radiation therapy as a part of their cancer treatment. Little is known, however, about the facilities that currently deliver external beam radiation. Our goal was to construct a comprehensive database of all radiation therapy facilities in the United States that can be used for future health services research in radiation oncology. Methods and Materials: From each state's health department we obtained a list of all facilities that have a linear accelerator or provide radiation therapy. We merged these state lists with information from the American Hospital Association (AHA), as well as 2 organizations that audit the accuracy of radiation machines: the Radiologic Physics Center (RPC) and Radiation Dosimetry Services (RDS). The comprehensive database included all unique facilities listed in 1 or more of the 4 sources. Results: We identified 2,246 radiation therapy facilities operating in the United States as of 2004-2005. Of these, 448 (20%) facilities were identified through state health department records alone and were not listed in any other data source. Conclusions: Determining the location of the 2,246 radiation facilities in the United States is a first step in providing important information to radiation oncologists and policymakers concerned with access to radiation therapy services, the distribution of health care resources, and the quality of cancer care

    The factors which must be considered in the process of adapting United States nuclear utility training programs to the needs of a European utility are discussed. Following a review of the present situation and drawing up of a new training program, the management commitments in terms of personnel and finance must be considered. Short term, medium and long term programs are outlined. The long term objectives should include the establishment of a total training centre. This facility should be capable of providing all the training necessary to operate a power plant safely. This would include specific simulator training, classroom training for operators, technician training, staff training, management training etc. In addition to a simulator, it should include an emergency response facility to train personnel.

  16. Nuclear power in the United States

    International Nuclear Information System (INIS)

    Johnston, J.B.

    1985-01-01

    All over the world except in the United States, nuclear energy is a low cost, secure, environmentally acceptable form of energy. In the United States, civilian nuclear power is dead. 112 nuclear power plants have been abandoned or cancelled in the last decade, and there has been no new order for nuclear plants since 1978. It will be fortunate to have 125 operating nuclear plants in the United States in the year 2000. There are almost 90 completed nuclear power plants and about 45 under construction in the United States, but several of those under construction will eventually be abandoned. About 20 % of the electricity in the United States will be generated by nuclear plants in 2000 as compared with 13 % supplied in the last year. Under the present regulatory and institutional arrangement, American electric utilities would not consider to order a new nuclear power plant. Post-TMI nuclear plants became very expensive, and there is also ideological opposition to nuclear power. Coal-firing plants are also in the similar situation. The uncertainty about electric power demand, the cost of money, the inflation of construction cost and regulation caused the situation. (Kako, I.)

    Since 1963, some irradiated foods have been permitted for sale in the United States. Yet, at this time, commercial application has been limited to irradiation of a relatively small fraction of the spices and seasonings used as ingredients in other foods. The current situation regarding irradiated foods in the United States and how it developed is discussed. The author writes from experience gained as a Government regulator concerned primarily with ensuring safety of food and therefore this is stressed together with the crucial role played by consumers and industry.

However, a large group of migrants in different economically developed countries have successfully launched businesses of diverse nature and volume. This is why entrepreneurship of migrants is an issue that has received increasing attention in recent years. Compared to other immigrant groups in the United States, Mexicans show low levels of entrepreneurial activity. The aim of this paper is to, through a general literature review of official statistical data, a preliminary analysis of mexican migrant entrepreneurship in the United States, that is to say in recent years has been growing in importance.

    Introduction Generating country-level political commitment will be critical to driving forward action throughout the United Nations Decade of Action on Nutrition (2016–2025). In this review of the empirical nutrition policy literature, we ask: what factors generate, sustain and constrain political commitment for nutrition, how and under what circumstances? Our aim is to inform strategic ‘commitment-building’ actions. Method We adopted a framework synthesis method and realist review protocol. An initial framework was derived from relevant theory and then populated with empirical evidence to test and modify it. Five steps were undertaken: initial theoretical framework development; search for relevant empirical literature; study selection and quality appraisal; data extraction, analysis and synthesis and framework modification. Results 75 studies were included. We identified 18 factors that drive commitment, organised into five categories: actors; institutions; political and societal contexts; knowledge, evidence and framing; and, capacities and resources. Irrespective of country-context, effective nutrition actor networks, strong leadership, civil society mobilisation, supportive political administrations, societal change and focusing events, cohesive and resonant framing, and robust data systems and available evidence were commitment drivers. Low-income and middle-income country studies also frequently reported international actors, empowered institutions, vertical coordination and capacities and resources. In upper-middle-income and high-income country studies, private sector interference frequently undermined commitment. Conclusion Political commitment is not something that simply exists or emerges accidentally; it can be created and strengthened over time through strategic action. Successfully generating commitment will likely require a core set of actions with some context-dependent adaptations. Ultimately, it will necessitate strategic actions by cohesive

  8. Fuzzy Stochastic Unit Commitment Model with Wind Power and Demand Response under Conditional Value-At-Risk Assessment

    Directory of Open Access Journals (Sweden)

    Jiafu Yin

    2018-02-01

    Full Text Available With the increasing penetration of wind power and demand response integrated into the grid, the combined uncertainties from wind power and demand response have been a challenging concern for system operators. It is necessary to develop an approach to accommodate the combined uncertainties in the source side and load side. In this paper, the fuzzy stochastic conditional value-at-risk criterions are proposed as the risk measure of the combination of both wind power uncertainty and demand response uncertainty. To improve the computational tractability without sacrificing the accuracy, the fuzzy stochastic chance-constrained goal programming is proposed to transfer the fuzzy stochastic conditional value-at-risk to a deterministic equivalent. The operational risk of forecast error under fuzzy stochastic conditional value-at-risk assessment is represented by the shortage of reserve resource, which can be further divided into the load-shedding risk and the wind curtailment risk. To identify different priority levels for the different objective functions, the three-stage day-ahead unit commitment model is proposed through preemptive goal programming, in which the reliability requirement has the priority over the economic operation. Finally, a case simulation is performed on the IEEE 39-bus system to verify the effectiveness and efficiency of the proposed model.

    2017-01-01

    Highlights: • A day–ahead wind–thermal unit commitment model is presented. • Wind speed transfer matrix is formed to depict the sequential wind features. • Spinning reserve setting considering wind power accuracy and variation is proposed. • Verified study is performed to check the correctness of the program. - Abstract: The increasing penetration of intermittent wind power affects the secure operation of power systems and leads to a requirement of robust and economic generation scheduling. This paper presents an optimal day–ahead wind–thermal generation scheduling method that considers the statistical and predicted features of wind speeds. In this method, the statistical analysis of historical wind data, which represents the local wind regime, is first implemented. Then, according to the statistical results and the predicted wind power, the spinning reserve requirements for the scheduling period are calculated. Based on the calculated spinning reserve requirements, the wind–thermal generation scheduling is finally conducted. To validate the program, a verified study is performed on a test system. Then, numerical studies to demonstrate the effectiveness of the proposed method are conducted.

  4. Both Europe's and the United States' electrification

    International Nuclear Information System (INIS)

    Matly, M.

    2006-01-01

    While the United States quickly had the largest electrical indus in the world, electrification in rural areas ended about thirty years after most European countries. Public intervention is a deciding factor in completing electrification, and the late involvement by the American authorities explains the gap. However it would be wrong to oppose in Europe and in the United States a motivated public sector and little involved private companies. In both continents indeed, major private and public urban distributors were almost not involved in rural electrification processes, where local players prevailed: local communities around Europe, small and medium size business in some European countries such as France, co-operative companies in the United States. Additionally, there is an essential difference between electrification in Europe and in the United States. The former does not provide much more than lighting and its success leaves few traces in popular memories; the latter includes many facilities and services, changes the lives of rural populations and is celebrated a such. Whereas the colonial venture keep European economies away from their domestic markets, while in the United States the urban market growth contents large companies, the American co-operative movement is right to believe in the existence of a large electrical equipment market among farmers then considered poor and behind. It even uses the market to complete a more profitable and less costly electrification. Electricity stories that offer food for the thoughts of Third World decision makers and power companies, when they entrust most rural electrification to their large urban companies and deny the existence of a real equipment market in their own rural world.

  15. An empirical study on measuring the effect of layoff on job satisfaction and employee commitment: A case study of detergent producer unit

    Directory of Open Access Journals (Sweden)

    Abolfazl Tajzadeh-Namin

    2012-01-01

    Full Text Available One of the necessary actions in many organizations is to reduce the number of workers in an attempt to restructure business activities. However, layoff could have negative consequences since many employees may decide to leave since they lose their tolerance. The layoff must be accompanied with some supportive plans to reduce stress among the remaining workers and increase their commitment for long-term work. The present study of this paper considers the effects of layoff on job satisfaction and commitment among the remaining employees of a detergent producer unit. The results indicate that a good supportive program including wage increase, family support, health care plans, etc. could significantly improve employee long-term commitments and it leads to job satisfaction.

  16. Antiabortion violence in the United States.

    Russo, Jennefer A; Schumacher, Kristin L; Creinin, Mitchell D

    2012-11-01

    This study was conducted to determine if an association exists between the amount of harassment and violence directed against abortion providers and the restrictiveness of state laws relating to family planning. We used responses from a July 2010 survey of 357 abortion providers in 50 states to determine their experience of antiabortion harassment and violence. Their responses were grouped and analyzed in relation to a published grading of state laws in the United States (A, B, C, D and F) as they relate to restrictions on family planning services. Group by group comparison of respondents illustrates that the difference in the number of reported incidents of minor vandalism by group is statistically significant (A vs. C, p=.07; A vs. D, p=.017; A vs. F, p=.0002). Incidents of harassment follow a similar pattern. There were no differences noted overall for violence or major vandalism. Major violence, including eight murders, is a new occurrence in the last two decades. Harassment of abortion providers in the United States has an association with the restrictiveness of state abortion laws. In the last two decades, murder of abortion providers has become an unfortunate part of the violence. Copyright © 2012 Elsevier Inc. All rights reserved.

  17. IAEA verification of weapon-origin fissile material in the Russian Federation and the United States

    International Nuclear Information System (INIS)

    2001-01-01

    The Secretary of Energy of the United States, Spencer Abraham, Minister of the Russian Federation on Atomic Energy, Alexander Rumyantsev, and Director General of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, met in Vienna on 18 September 2001 to review progress on the Trilateral Initiative. The Initiative was launched in 1996 to develop a new IAEA verification system for weapon-origin material designated by the United States and the Russian Federation as released from their defence programmes. The removal of weapon-origin fissile material from the defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification under this Initiative is intended to promote international confidence that fissile material made subject by either of the two States to Agency verification remains irreversibly removed from nuclear weapon programmes

    Fishman, J A; Allison, H; Knowles, S B; Fishburn, B A; Woollery, T A; Marx, W T; Shelton, D M; Husten, C G; Eriksen, M P

    1999-06-25

    State laws addressing tobacco use, the leading preventable cause of death in the United States, are summarized. Laws address smoke-free indoor air, minors' access to tobacco products, advertising of tobacco products, and excise taxes on tobacco products. Legislation effective through December 31, 1998. CDC identified laws addressing tobacco control by using an on-line legal research database. CDC's findings were verified with the National Cancer Institute's State Cancer Legislative Database. Since a previous surveillance summary on state tobacco-control laws published in November 1995 (covering legislation effective through June 30, 1995), several states have enacted new restrictions or strengthened existing legislation that addresses smoke-free indoor air, minors' access to tobacco, tobacco advertising, and tobacco taxes. Five states strengthened their smoke-free indoor air legislation. All states and Washington, D.C., continued to prohibit the sale and distribution of tobacco products to minors; however, 21 states expanded minors' access laws by designating enforcement authorities, adding license suspension or revocation for sale to minors, or requiring signage. Since the 1995 report, eight additional states (a total of 19 states and Washington, D.C.) now ban vending machines from areas accessible to minors. Thirteen states restrict advertising of tobacco products, an increase of four states since the 1995 report. Although the number of states that tax cigarettes and smokeless tobacco did not change, 13 states increased excise taxes on cigarettes, and five states increased excise taxes on smokeless tobacco products. The average state excise tax on cigarettes is 38.9 cents per pack, an increase of 7.4 cents compared with the average tax in the 1995 report. State laws addressing tobacco control vary in relation to restrictiveness, enforcement and penalties, preemptions, and exceptions. The data summarizing state tobacco-control laws are available through CDC

  10. The United States and world energy markets

    International Nuclear Information System (INIS)

    Ramsay, W.C.

    1992-01-01

    The United States, dominating the world's energy markets as a producer and consumer, is sensitive to changes in this market and intends to influence the development of global energy policy. Supply will be increased by nations such as Venezuela, Indonesia and perhaps in the future a United Yemen and the Commonwealth of Independent States, moving to freer market economies which will allow investment opportunities previously inaccessible to foreign companies. Although world energy demand will grow, little of this will be in the US where, under the National Energy Strategy, comprehensive measures are being introduced to improve energy efficiency. The US energy security will be further improved by such measures as diversification of supply, larger domestic production and increasing interdependence between suppliers, traders and consumers.

    The United States has produced this report as part of the preparations for the United Nations Conference on Environment and Development (UNCED) to be held in Brazil in June 1992. It summarizes this nation's efforts to protect and enhance the quality of the human environment in concert with its efforts to provide economic well-being during the two decades since the United Nations Conference on the Human Environment was held in Stockholm. The information presented in this report is primarily and deliberately retrospective. It is an attempt to portray the many human, economic and natural resources of the United States, to describe resource use and the principal national laws and programs established to protect these resources, and to analyze key issues on the agenda of UNCED. This analysis is presented in terms of past and present conditions and trends, measures of progress made in responding to the key issues, and a summary of government activities, underway or pending, to address ongoing or newly emerging national environmental and resource management problems

    2006-01-01

    The activity concentration of 222 Rn, 226 Ra and total uranium in groundwater samples collected from wells distributed throughout the state of Chihuahua has been measured. The values obtained of total uranium activity concentration in groundwater throughout the state run from -1 . Generally, radium activity concentration was -1 , with some exceptions; in spring water of San Diego de Alcala, in contrast, the value reached ∼5.3 Bq l -1 . Radon activity concentration obtained throughout the state was from 1.0 to 39.8 Bq l -1 . A linear correlation between uranium and radon dissolved in groundwater of individual wells was observed near Chihuahua City. Committed effective dose estimates for reference individuals were performed, with results as high as 134 μSv for infants in Aldama city. In Aldama and Chihuahua cities the average and many individual wells showed activity concentration values of uranium exceeding the Mexican norm of drinking water quality. (authors)

The United States will have to incorporate these changes into its global strategies

  15. Low birth weight in the United States.

    Science.gov (United States)

    Goldenberg, Robert L; Culhane, Jennifer F

    2007-02-01

    Pregnancy outcomes in the United States and other developed countries are considerably better than those in many developing countries. However, adverse pregnancy outcomes are generally more common in the United States than in other developed countries. Low-birth-weight infants, born after a preterm birth or secondary to intrauterine growth restriction, account for much of the increased morbidity, mortality, and cost. Wide disparities exist in both preterm birth and growth restriction among different population groups. Poor and black women, for example, have twice the preterm birth rate and higher rates of growth restriction than do most other women. Low birth weight in general is thought to place the infant at greater risk of later adult chronic medical conditions, such as diabetes, hypertension, and heart disease. Of interest, maternal thinness is a strong predictor of both preterm birth and fetal growth restriction. However, in the United States, several nutritional interventions, including high-protein diets, caloric supplementation, calcium and iron supplementation, and various other vitamin and mineral supplementations, have not generally reduced preterm birth or growth restriction. Bacterial intrauterine infections play an important role in the etiology of the earliest preterm births, but, at least to date, antibiotic treatment either before labor for risk factors such as bacterial vaginosis or during preterm labor have not consistently reduced the preterm birth rate. Most interventions have failed to reduce preterm birth or growth restriction. The substantial improvement in newborn survival in the United States over the past several decades is mostly due to better access to improved neonatal care for low-birth-weight infants.

    An important feature of the restructuring process in the United States is the creation of independent system operators (ISOs) to coordinate dispatch and access to transmission grids. A number of ISOs have been proposed and are summarized here. Perhaps the greatest challenge is the pricing of transmission to give proper economic signals to market participants, and the locational pricing scheme now operating in the PJM system offers the best hope for efficient pricing.

    The United States policy on severe accidents was published in 1985 for both new plant applications and for existing plants. Implementation of this policy is in progress. This policy, aided by a related safety goal policy and by analysis capabilities emerging from improved understanding of accident phenomenology, is viewed as a logical development from the pioneering work in the WASH-1400 Reactor Safety Study published by the United States Nuclear Regulatory Commission (NRC) in 1975. This work provided an estimate of the probability and consequences of severe accidents which, prior to that time, had been mostly evaluated by somewhat arbitrary assumptions dating back 30 years. The early history of severe accident evaluation is briefly summarized for the period 1957-1979. Then, the galvanizing action of Three Mile Island Unit 2 (TMI-2) on severe accident analysis, experimentation and regulation is reviewed. Expressions of US policy in the form of rulemaking, severe accident policy, safety research, safety goal policy and court decisions (on adequacy of safety) are discussed. Finally, the NRC policy as of March 1988 is stated, along with a prospective look at the next few years. (author). 19 refs

    In accordance with the Southern States Energy Board (SSEB) proposal, as incorporated into NETL/DE-FC26-97FT34199, the objective of this agreement is to streamline the environmental technology permitting process site-to-site, state-to-state, and industry-to-industry to achieve remediation and waste processing faster, better and cheaper. SSEB is working with member Governors, legislators and regulators to build consensus on streamlining the permitting process for new and innovative technologies for addressing the legacy of environmental problems from 50 years of weapons research, development and production. This report reviews mechanisms whereby industry consortiums and the Department of Energy (DOE) have been working with State regulators and other officials in technology deployment decisions within the DOE complex. The historic development of relationships with State regulators is reviewed and the current nature of the relationships examined. The report contains observations from internal DOE reviews as well as recommendations from the General Accounting Office (GAO) and other external organizations. The report discusses reorganization initiatives leading up to a DOE Top-to-Bottom review of the Environmental Management (EM) Program and highlights points of consideration for maintaining effective linkages with State regulators. It notes how the proposed changes will place new demands upon the National Energy Technology Laboratory (NETL) and how NETL can leverage its resources by refocusing existing EM efforts specifically to states that have DOE facilities within their borders (host-states). Finally, the report discusses how SSEB's Permitting Leadership in the United States (PLUS) program can provide the foundation for elements of NETL's technical assistance program that are delivered to regulators and other decision- makers in host-states. As a regional compact commission, SSEB provides important direct linkages to regulators and stakeholders who need technical

  9. Human prion diseases in the United States.

    Full Text Available BACKGROUND: Prion diseases are a family of rare, progressive, neurodegenerative disorders that affect humans and animals. The most common form of human prion disease, Creutzfeldt-Jakob disease (CJD, occurs worldwide. Variant CJD (vCJD, a recently emerged human prion disease, is a zoonotic foodborne disorder that occurs almost exclusively in countries with outbreaks of bovine spongiform encephalopathy. This study describes the occurrence and epidemiology of CJD and vCJD in the United States. METHODOLOGY/PRINCIPAL FINDINGS: Analysis of CJD and vCJD deaths using death certificates of US residents for 1979-2006, and those identified through other surveillance mechanisms during 1996-2008. Since CJD is invariably fatal and illness duration is usually less than one year, the CJD incidence is estimated as the death rate. During 1979 through 2006, an estimated 6,917 deaths with CJD as a cause of death were reported in the United States, an annual average of approximately 247 deaths (range 172-304 deaths. The average annual age-adjusted incidence for CJD was 0.97 per 1,000,000 persons. Most (61.8% of the CJD deaths occurred among persons >or=65 years of age for an average annual incidence of 4.8 per 1,000,000 persons in this population. Most deaths were among whites (94.6%; the age-adjusted incidence for whites was 2.7 times higher than that for blacks (1.04 and 0.40, respectively. Three patients who died since 2004 were reported with vCJD; epidemiologic evidence indicated that their infection was acquired outside of the United States. CONCLUSION/SIGNIFICANCE: Surveillance continues to show an annual CJD incidence rate of about 1 case per 1,000,000 persons and marked differences in CJD rates by age and race in the United States. Ongoing surveillance remains important for monitoring the stability of the CJD incidence rates, and detecting occurrences of vCJD and possibly other novel prion diseases in the United States.

    1972-01-01

    The use of energy may be constrained by a growing national consensus that we must choose; future courses that minimize adverse effect on public health, public safety, and the environment. It is believed nuclear power will be able to meet this challenge - more adequately than most fossil fuels. Thus it follows that the growth of nuclear power will be fostered by this trend. The United States today has contractual commitments of about 150 power plants with total capacity of about 130 million kilowatts electrical. When all of these plants are on line, by about 1980, that capacity will be equal to about 35% of our present electrical generating capacity. Of these commitments, 95% are for light water reactors - 62% for pressurized water and 33% for boiling water. The remaining 5% are high- temperature gas-cooled reactors. In this period of rapid expansion we are placing heavy emphasis on programmes to achieve higher levels of standardization, with the objective of improvements in safety, reliability and economics. Standardization will also shorten licensing reviews, provide for efficiency of labour and reduce maintenance problems. Meanwhile, improved technology in heat rejection techniques such as dry cooling will help to minimize the environmental problems, in addition, methods may be introduced to use rejected heat for beneficial purposes, such as food production in agriculture and aquaculture, as well as urban and industrial applications. Also during this period, biological research can be expected to result in continued progress toward identifying and understanding the effects of energy generation on man and his environment. With this increased knowledge, we will be better able to make wise decisions regarding the most effective use of all energy sources. The next major development step is the breeder reactor, which will achieve maximum utilization of fission fuels

  12. Taxation of United States general aviation

    Science.gov (United States)

    Sobieralski, Joseph Bernard

    General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994-2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and

  2. State cigarette minimum price laws - United States, 2009.

    Science.gov (United States)

    2010-04-09

    Cigarette price increases reduce the demand for cigarettes and thereby reduce smoking prevalence, cigarette consumption, and youth initiation of smoking. Excise tax increases are the most effective government intervention to increase the price of cigarettes, but cigarette manufacturers use trade discounts, coupons, and other promotions to counteract the effects of these tax increases and appeal to price-sensitive smokers. State cigarette minimum price laws, initiated by states in the 1940s and 1950s to protect tobacco retailers from predatory business practices, typically require a minimum percentage markup to be added to the wholesale and/or retail price. If a statute prohibits trade discounts from the minimum price calculation, these laws have the potential to counteract discounting by cigarette manufacturers. To assess the status of cigarette minimum price laws in the United States, CDC surveyed state statutes and identified those states with minimum price laws in effect as of December 31, 2009. This report summarizes the results of that survey, which determined that 25 states had minimum price laws for cigarettes (median wholesale markup: 4.00%; median retail markup: 8.00%), and seven of those states also expressly prohibited the use of trade discounts in the minimum retail price calculation. Minimum price laws can help prevent trade discounting from eroding the positive effects of state excise tax increases and higher cigarette prices on public health.

    In the United States, three technologies are employed for the new generation of advanced reactors. These technologies are Advanced Light Water Reactors (A LWRs) for the 1990s and beyond, the Modular High Temperature Gas Reactor (M HTGR) for commercial use after the turn of the century, and Liquid Metal Reactors (LWRs) to provide energy production and to convert reactor fission waste to a more manageable waste product. Each technology contributes to the energy solution. Light Water Reactors For The 1990s And Beyond--The U. S. Program The economic and national security of the United States requires a diversified energy supply base built primarily upon adequate, domestic resources that are relatively free from international pressures. Nuclear energy is a vital component of this supply and is essential to meet current and future national energy demands. It is a safe, economically continues to contribute to national energy stability, and strength. The Light Water Reactor (LWR) has been a major and successful contributor to the electrical generating needs of many nations throughout the world. It is being counted upon in the United States as a key to revitalizing nuclear energy option in the 1990s. In recent years, DOE joined with the industry to ensure the availability and future viability of the LWR option. This national program has the participation of the Nation's utility industry, the Electric Power Research Institute (EPRI), and several of the major reactor manufacturers and architect-engineers. Separate but coordinated parts of this program are managed by EPRI and DOE.

    Uranium mining in the United States is closer to 100 years old than to the 200 years since the discovery of the element. Even then, for much of this time the rock was brought out of the ground for reasons other than its uranium content. The history of the US uranium industry is divided into five periods which follow roughly chronologically upon one another, although there is some overlap. The periods cover: uranium use in glass and ceramics; radium extraction; vanadium extraction; government uranium extraction and commercial extraction. (author)

    The United States of America is the world's largest market for uranium enrichment services. After the disintegration of the Soviet Union, Russian uranium is entering the world market on an increasing scale. The U.S. tries to protect its market and, in this connection, also the European market from excessive price drops by taking anti-dumping measures. In order to become more competitive, American companies have adapted modern enrichment techniques from Europe. European - U.S. joint ventures are to help, also technically and economically, to integrate military uranium, accumulating as a consequence of worldwide disarmament, into the commercial fuel cycle for the peaceful use of nuclear power.

    Acceptance and Commitment Therapy (ACT) has growing support for chronic pain. However, more accessible treatment delivery is needed. This study evaluated the feasibility of online ACT for patients with complex chronic pain in the United Kingdom to determine whether a larger trial is justified. Participants with chronic pain and clinically meaningful disability and distress were randomly assigned to ACT online plus specialty medical pain management, or specialty medical management alone. Participants completed questionnaires at baseline, and 3- and 9-month post-randomization. Primary feasibility outcomes included recruitment, retention and treatment completion rates. Secondary outcomes were between-groups effects on treatment outcomes and psychological flexibility. Of 139 potential participants, 63 were eligible and randomized (45% recruitment rate). Retention rates were 76-78% for follow-up assessments. Sixty-one per cent of ACT online participants completed treatment. ACT online was less often completed by employed (44%) compared to unemployed (80%) participants. Fifty-six per cent of ACT online participants rated themselves as 'much improved' or better on a global impression of change rating, compared to only 20 per cent of control participants. Three-month effects favouring ACT online were small for functioning, medication and healthcare use, committed action and decentring, medium for mood, and large for acceptance. Small-to-medium effects were maintained for functioning, healthcare use and committed action at 9 months. Online ACT for patients with chronic pain in the United Kingdom appears feasible to study in a larger efficacy trial. Some adjustments to treatment and trial procedures are warranted, particularly to enhance engagement among employed participants. This study supports the feasibility of online Acceptance and Commitment Therapy for chronic pain in the United Kingdom and a larger efficacy trial. Refinements to treatment delivery, particularly to

    Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Although the majority of infants conceived through ART are singletons, women who undergo ART procedures are more likely than women who conceive naturally to deliver multiple-birth infants. Multiple births pose substantial risks for both mothers and infants, including obstetric complications, preterm delivery (state-specific information for the United States (including the District of Columbia and Puerto Rico) on ART procedures performed in 2015 and compares birth outcomes that occurred in 2015 (resulting from ART procedures performed in 2014 and 2015) with outcomes for all infants born in the United States in 2015. 2015. In 1995, CDC began collecting data on ART procedures performed in fertility clinics in the United States as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493 [October 24, 1992]). Data are collected through the National ART Surveillance System, a web-based data collection system developed by CDC. This report includes data from 52 reporting areas (the 50 states, the District of Columbia, and Puerto Rico). In 2015, a total of 182,111 ART procedures (range: 135 in Alaska to 23,198 in California) with the intent to transfer at least one embryo were performed in 464 U.S. fertility clinics and reported to CDC. These procedures resulted in 59,334 live-birth deliveries (range: 55 in Wyoming to 7,802 in California) and 71,152 infants born (range: 68 in Wyoming to 9,176 in California). Nationally, the number of ART procedures performed per 1 million women of reproductive age (15-44 years), a proxy measure of the ART utilization rate, was

  20. License renewal in the United States

    Full text: Nuclear plants in the United States are licensed for 40 years, a length specified in the Atomic Energy Act of 1954, which laid out much of the regulatory basis for the commercial nuclear industry. The Act, however, made provision for license renewal. The original 40-year license period was chosen arbitrarily by the U.S. Congress because it was the typical period over which utilities recovered their investment in electricity generating plants. Nuclear plants, however, are subject to a rigorous program of Nuclear Regulatory Commission oversight, maintenance and equipment replacement. In effect, they must be in the same operating condition on the last day of their licenses as they were on the first. As the industry matured, it became apparent that there was no physical limitation on the continued operation of nuclear plants past 40 years. The industry turned its attention toward license renewal. When the issue was first raised, the NRC considered stringent process equivalent to seeking a new operating license for each plant. The complexity, length and cost of the process made it unlikely that many nuclear plants would seek license renewal. The nuclear industry worked successfully with NRC on the application of generic principles to license renewal, however, and in 1995, the NRC issued an efficient, tightly-focused rule that made license renewal a safe, viable option. To extend the operating license for a reactor, a company must demonstrate to the NRC that aging effects will be adequately managed during the renewal terms, thus ensuring equipment functionality. The rule allows licensees to apply for extensions of up to 20 years. The first license renewal application was filed in 1998 by the owner of the two-unit Calvert Cliffs plant. Shortly thereafter, an application was filed for the three-unit Oconee Nuclear Station. The NRC renewed the licenses for all five units in 2000, and since then, five more licenses have been renewed. The NRC has received 37

    The Renewable Energy Atlas (Atlas) of the United States is a compilation of geospatial data focused on renewable energy resources, federal land ownership, and base map reference information. It is designed for the U.S. Department of Agriculture Forest Service (USFS) and other federal land management agencies to evaluate existing and proposed renewable energy projects. Much of the content of the Atlas was compiled at Argonne National Laboratory (Argonne) to support recent and current energy-related Environmental Impact Statements and studies, including the following projects: (1) West-wide Energy Corridor Programmatic Environmental Impact Statement (PEIS) (BLM 2008); (2) Draft PEIS for Solar Energy Development in Six Southwestern States (DOE/BLM 2010); (3) Supplement to the Draft PEIS for Solar Energy Development in Six Southwestern States (DOE/BLM 2011); (4) Upper Great Plains Wind Energy PEIS (WAPA/USFWS 2012, in progress); and (5) Energy Transport Corridors: The Potential Role of Federal Lands in States Identified by the Energy Policy Act of 2005, Section 368(b) (in progress). This report explains how to add the Atlas to your computer and install the associated software; describes each of the components of the Atlas; lists the Geographic Information System (GIS) database content and sources; and provides a brief introduction to the major renewable energy technologies.

  4. Step-grandparenthood in the United States.

    2018-01-18

    This study provides new information about the demography of step-grandparenthood in the United States. Specifically, we examine the prevalence of step-grandparenthood across birth cohorts and for socioeconomic and racial/ethnic groups. We also examine lifetime exposure to the step-grandparent role. Using data from the Panel Study of Income Dynamics and the Health and Retirement Study, we use percentages to provide first estimates of step-grandparenthood and to describe demographic and socioeconomic variation in who is a step-grandparent. We use life tables to estimate the exposure to step-grandparenthood. The share of step-grandparents is increasing across birth cohorts. However, individuals without a college education and non-Whites are more likely to become step-grandparents. Exposure to the step-grandparent role accounts for approximately 15% of total grandparent years at age 65 for women and men. A growing body of research finds that grandparents are increasingly instrumental in the lives of younger generations. However, the majority of this work assumes that these ties are biological, with little attention paid to the role of family complexity across three generations. Understanding the demographics of step-grandparenthood sheds light on the family experiences of an overlooked, but growing segment of the older adult population in the United States. © The Author(s) 2018.

    Nine-banded armadillos (Dasypus novemcinctus) are naturally infected with Mycobacterium leprae and have been implicated in zoonotic transmission of leprosy. Early studies found this disease mainly in Texas and Louisiana, but armadillos in the southeastern United States appeared to be free of infection. We screened 645 armadillos from 8 locations in the southeastern United States not known to harbor enzootic leprosy for M. leprae DNA and antibodies. We found M. leprae–infected armadillos at each location, and 106 (16.4%) animals had serologic/PCR evidence of infection. Using single-nucleotide polymorphism variable number tandem repeat genotyping/genome sequencing, we detected M. leprae genotype 3I-2-v1 among 35 armadillos. Seven armadillos harbored a newly identified genotype (3I-2-v15). In comparison, 52 human patients from the same region were infected with 31 M. leprae types. However, 42.3% (22/52) of patients were infected with 1 of the 2 M. leprae genotype strains associated with armadillos. The geographic range and complexity of zoonotic leprosy is expanding.

    Six multichannel seismic-reflection profiles taken across the Atlantic continental margin Previous HitoffTop the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin. Beneath the continental rise, the sedimentary prism thickness exceeds 7 km south of New Jersey and Maryland, and it is 4.5 km thick south of Georges Bank. Stratigraphically, the continental slope--outer edge of the continental shelf is a transition zone of high-velocity sedimentary rock, probably carbonate, that covers deeply subsided basement. Acoustically, the sedimentary sequence beneath the shelf is divided into three units which are correlated speculatively with the Cenozoic, the Cretaceous, and the Jurassic-Triassic sections. These units thicken offshore, and some have increased seismic velocities farther offshore. The uppermost unit thickens from a fraction of a kilometer to slightly more than a kilometer in a seaward direction, and velocity values range from 1.7 to 2.2 km/sec. The middle unit thickens from a fraction of a kilometer to as much as 5 km (northern Baltimore Canyon trough), and seismic velocity ranges from 2.2 to 5.4 km/sec. The lowest unit thickens to a maximum of 9 km (northern Baltimore Canyon), and velocities span the 3.9 to 5.9-km/sec interval. The spatial separation of magnetic and gravity anomalies on line 2 (New Jersey) suggests that in the Baltimore Canyon region the magnetic-slope anomaly is due to edge effects and that the previously reported free-air and isostatic gravity anomalies over the outer shelf may be due in part to a lateral increase in sediment density (velocity) near the shelf edge. The East Coast magnetic anomaly and the free-air gravity high both coincide over the outer shelf edge on line 1 (Georges Bank) but are offset by 20 km from the ridge on the reflection profile. Because the magnetic-slope-anomaly wavelength is nearly 50 km across, a

  8. A United States regulator's perspective on the ongoing chlorofluorocarbon transition.

    Meyer, R J

    1999-12-01

    The Food and Drug Administration (FDA) put in place a general ban on the use of chlorofluorocarbons for the products it regulates (medical devices, drugs, and foods) in 1978, exempting those products where chlorofluorocarbon use was determined to be essential for the public health. In the intervening years, as the international commitment to a full transition away from all chlorofluorocarbon use took shape under the Montreal Protocol, the FDA has worked with industry to facilitate the development and testing of alternative technologies and products for inhalation drug products. As these alternative products begin to move from testing through the approval process and into marketing, the FDA is working collaboratively with the Environmental Protection Agency, other governmental agencies, and nongovernmental stakeholders to develop a transition policy for the United States. The transition policy for metered dose inhalers must be one that achieves the dual aims of first protecting the patients who rely on these vital medical products, while also achieving the public health need of protecting the ozone layer. As a part of developing such a transition strategy, the FDA published an advance notice of proposed rulemaking (ANPRM) in March 1997. The ANPRM proposed mechanisms by which the FDA could determine when chlorofluorocarbon use in a drug product could no longer be considered essential. The ANPRM resulted in a large amount of valuable public debate and input. The FDA is now working to incorporate the knowledge gained from these public comments as it continues the rule-making process.

  9. The water needs for LDV transportation in the United States

    King, Carey W.; Webber, Michael E.; Duncan, Ian J.

    2010-01-01

    Concern over increased demand for petroleum, reliable fuel supply, and global climate change has resulted in the US government passing new Corporate Average Fuel Economy standards and a Renewable Fuels Standard. Consequently, the fuel mix for light duty vehicle (LDV) travel in the United States will change over the coming years. This paper explores the embodied water consumption and withdrawal associated with two projections for future fuel use in the US LDV sector. This analysis encompasses conventional and unconventional fossil fuels, corn ethanol, cellulosic ethanol, soy biodiesel, electricity, and hydrogen. The existing mandate in the US to blend ethanol into gasoline had effectively committed 3300 billion liters of irrigation water in 2005 (approximately 2.4% of US 2005 fresh water consumption) for producing fuel for LDVs. With current irrigation practices, fuel processing, and electricity generation, it is estimated that by 2030, approximately 14,000 billion liters of water per year will be consumed and 23,000-27,000 billion liters withdrawn to produce fuels used in LDVs. Irrigation for biofuels dominates projected water usage for LDV travel, but other fuels (coal to liquids, oil shale, and electricity via plug-in hybrid vehicles) will also contribute appreciably to future water consumption and withdrawal, especially on a regional basis.

    This analysis of the United States health system reviews the developments in organization and governance, health financing, health-care provision, health reforms and health system performance. The US health system has both considerable strengths and notable weaknesses. It has a large and well-trained health workforce, a wide range of high-quality medical specialists as well as secondary and tertiary institutions, a robust health sector research program and, for selected services, among the best medical outcomes in the world. But it also suffers from incomplete coverage of its citizenry, health expenditure levels per person far exceeding all other countries, poor measures on many objective and subjective measures of quality and outcomes, an unequal distribution of resources and outcomes across the country and among different population groups, and lagging efforts to introduce health information technology. It is difficult to determine the extent to which deficiencies are health-system related, though it seems that at least some of the problems are a result of poor access to care. Because of the adoption of the Affordable Care Act in 2010, the United States is facing a period of enormous potential change. Improving coverage is a central aim, envisaged through subsidies for the uninsured to purchase private insurance, expanded eligibility for Medicaid (in some states) and greater protection for insured persons. Furthermore, primary care and public health receive increased funding, and quality and expenditures are addressed through a range of measures. Whether the ACA will indeed be effective in addressing the challenges identified above can only be determined over time.

  16. Status of fast breeder reactor development in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Rosen, S

    1979-07-01

    This document was prepared by the Office of the Program Director for Nuclear Energy, U.S. Department of Energy (USDOE). It sets forth the status and current activities for the development of fast breeder technology in the United States. In April 1977 the United States announced a change in its nuclear energy policy. Concern about the potential for the proliferation of nuclear weapons capability emerged as a major issue in considering whether to proceed with the development, demonstration and eventual deployment of breeder reactor energy systems. Plutonium recycle and the commercialization of the fast breeder were deferred indefinitely. This led to a reorientation of the nuclear fuel cycle program which was previously directed toward the commercialization of fuel reprocessing and plutonium recycle to the investigation of a full range of alternative fuel cycle technologies. Two major system evaluation programs, the Nonproliferation Alternative Systems Assessment Program (NASAP), which is domestic, and the International Nuclear Fuel Cycle Evaluation (INFCE), which is international, are assessing the nonproliferation advantages and other characteristics of advanced reactor concepts and fuel cycles. These evaluations will allow a decision in 1981 on the future direction of the breeder program. In the interim, the technologies of two fast breeder reactor concepts are being developed: the Liquid Metal Fast Breeder Reactor (LMFBR) and the Gas Cooled Fast Reactor (CFR). The principal goals of the fast breeder program are: LMFBR - through a strong R and D program, consistent with US nonproliferation objectives and anticipated national electric energy requirements, maintain the capability to commit to a breeder option; investigate alternative fuels and fuel cycles that might offer nonproliferation advantages; GCFR - provide a viable alternative to the LMFBR that will be consistent with the developing U.S. nonproliferation policy; provide GCFR technology and other needed

    Air pollution in the United States as a problem affecting health, as well as man's enjoyment of his property, was first noted in 1912 in the reports of the investigators at the Mellon Institute of the University of Pittsburgh. The Selby copper smelter incident in 1915 was among the first episodic air pollution events documented. The US Public Health Service studied carbon monoxide buildup in vehicular tunnels in 1928 and 1929. the Donora (Pennsylvania) pollution episode, where 17 people died, occurred in 1949. It and the onset of smog conditions in the Los Angeles area really initiated broad public awareness of air pollution as a public health hazard in the USA. The symptoms of air pollution-related injuries are discussed, the role of the US Public Health Service in dealing with air pollution, and the effect of the Clean Air Act of 1963 are discussed. 26 references.

    This report summarizes the primary scientific activities of the United States Transuranium and Uranium Registries for the period October 1, 1989 through September 30, 1990. The Registries are parallel human tissue research programs devoted to the study of the actinide elements in humans. To date there have been 261 autopsy or surgical specimen donations, which include 11 whole bodies. The emphasis of the Registry was directed towards quality improvement and the development of a fully computerized data base that would incorporate not only the results of postmortem radiochemical analysis, but also medical and monitoring information obtained during life. Human subjects reviews were also completed. A three compartment biokinetic model for plutonium distribution is proposed. 2 tabs

The experience began with the licensing of the Peach Bottom Atomic Power Station and extends to the continuing experience at the Fort St. Vrain Nuclear Generating Station. Additional experience was obtained from the licensing reviews in the mid-1970s of the large HTGR plants that were to be built by Philadelphia Electric Company and Delmarva Power and Light. Also, information was provided by the licensing review of the General Atomic standard plant by the U.S. Nuclear Regulatory Commission (NRC) at about the same time. These experiences are summarized in terms of the principal design criteria that were required by the regulatory authority for each project. These criteria include specification of the design basis accidents that were postulated for the plant safety analysis. Several technical issues raised by the NRC during their review of the large HTGR are presented. (author)

    Wholesale trade in electricity plays an important role for the US electric utility industry. Wholesale, or bulk power, transactions allow electric utilities to reduce power costs, increase power supply options, and improve reliability. In 1994, the wholesale trade market totaled 1.9 trillion kilowatthours, about 66% of total sales to ultimate consumers. This publication, Electric Trade in the United States 1994 (ELECTRA), is the fifth in a series of reports on wholesale power transactions prepared by the Office of Coal, Nuclear, Electric and Alternate Fuels, Energy Information Administration (EIA).

    Standards to protect workers and members of the general public against any harmful effects of ionizing radiation are numerous and complex in the United States. Many Federal agencies have protection responsibilities, our Congress limits the discretionary authority given to these agencies in providing for this protection, and our court system appears at times to render judgments that are illogical to our sense of the degree of radiological protection required. To many our standards appear to be overprotective in that they have, at best, marginal health benefits and without question are costly to implement. Government agencies, the Congress, industry, professional organizations, and others have expressed their concerns and interests regarding standards in a variety of ways

    The Department of Energy has defined a safeguards system to be an integrated system of physical protection, material accounting and material control subsystems designed to deter, prevent, detect, and respond to unauthorized possession, use, or sabotage of SNM. In practice, safeguards involve the development and application of techniques and procedures dealing with the establishment and continued maintenance of a system of activities. The system must also include administrative controls and surveillance to assure that the procedures and techniques of the system are effective and are being carried out. The control of nuclear material is critical to the safeguarding of nuclear materials within the United States. The U.S. Department of Energy includes as part of material control four functional performance areas. They include access controls, material surveillance, material containment and detection/assessment. This paper will address not only these areas but also the relationship between material control and other safeguards and security functions

    The United States are certainly the country which is the most concerned by a better evaluation of uranium resources. This is so because of the importance of the American nuclear program and because of a certain number of doubts in their uranium supply. This is probably why studies concerning American uranium resources have been very frequent in recent months. Although, most of these studies are not yet finished it is perhaps possible to draw a few conclusions in order to better see the framework of this important uranium resources problem. This is what this article attempts, using among other studies, the one carried-out for the National Science Foundation which is among the most complete, especially concerning the complete range of resources [fr

    Full Text Available Southeast Asia has historically been a meeting point between East Asia and South Asia before Western colonialism opened the region to the West and to the winds of global modernization. Since Japan’s coercive decolonization during the Second World War, the dominant outside influences have come from the United States and from the People’s Republic of China. The post-Cold War era began with a withdrawal of both China’s and US power projection from Southeast Asia, facilitating the configuration of a triangular ménage à trios, with ASEAN expanding to include all of Southeast Asia and introducing a number of extended forums intended to socialize the rest of East Asia into the ASEAN way. The “rise of China” occurred within this friendly context, though beginning around 2010 its strategic implications began to appear more problematic with the mounting dispute over the issue of the South China Sea.

    The issues of financial protection contemplate appropriate financing to permit construction of the involved vessels. In addition, the licensing process will require a demonstrated ability for financial response in the event of injury to persons or damage to property. Since the thrust in the United States is to use the Price-Anderson framework for Insurance and Indemnity, much attention is devoted to this legislation. The pre-existing regime is related to the distinguishing requirements of the Maritime field with proposals being advanced to more nearly parallel the insurance coverage philosophy of Europe, i.e., to utilize insurance pools for the nuclear risks and utilize the conventional insurance market for non-nuclear risks. Public affairs issues impact heavily on legislation efforts and thusly become significant in developing a program for Financial Protection

    Fabbri, Marilyn; Maslow, Melanie J.

    2001-06-01

    Since the first outbreak of hantavirus pulmonary syndrome (HPS) in 1993, understanding of the vast distribution and potential impact of hantaviruses has grown. At least 277 cases of HPS have been documented in the United States. The full clinical spectrum has yet to be elucidated, and one outbreak suggested the possibility of person-to-person transmission. New research has identified the b-3 integrins as cellular receptors for hantaviruses and has determined the pivotal role of the immune system in pathogenesis. Rapid diagnosis has been facilitated by a new immunoblot assay to detect Sin Nombre virus infection. Treatment remains primarily supportive; however, a placebo- controlled trial of ribavirin is ongoing. Extracorporeal membrane oxygenation may be a potential therapy in severe cases; inhaled nitric oxide needs further study. Vaccines developed against hantaviruses associated with hemorrhagic fever and renal syndrome might be effective against HPS-associated strains.

  10. Unplanned pregnancies in the United States.

    1986-03-01

    Unplanned pregnancies constitute an epidemic in the United States. Over 3 million unplanned pregnancies occur, and over 1.5 million induced abortions are performed each year. Women of minority races and those with less than 12 years of education are at high risk of having unwanted children. Fear of complications (not the complications themselves) is the most powerful deterrent to women's use of contraception. Much of this fear is due to bad press. Recent good news about contraception, such as protection against ovarian and endometrial cancer, protection against ectopic pregnancy, and absence of teratogenic effects, has not received appropriate media coverage. For healthy women younger than 35 years, failure to use fertility control is more dangerous than use of any method.

  11. Electric trade in the United States 1994

    International Nuclear Information System (INIS)

    1998-08-01

    Wholesale trade in electricity plays an important role for the US electric utility industry. Wholesale, or bulk power, transactions allow electric utilities to reduce power costs, increase power supply options, and improve reliability. In 1994, the wholesale trade market totaled 1.9 trillion kilowatthours, about 66% of total sales to ultimate consumers. This publication, Electric Trade in the United States 1994 (ELECTRA), is the fifth in a series of reports on wholesale power transactions prepared by the Office of Coal, Nuclear, Electric and Alternate Fuels, Energy Information Administration (EIA). The electric trade data are published biennially. The first report presented 1986 data, and this report provides information on the electric power industry during 1994

  18. A proposed United States resource classification system

    International Nuclear Information System (INIS)

    Masters, C.D.

    1980-01-01

    Energy is a world-wide problem calling for world-wide communication to resolve the many supply and distribution problems. Essential to a communication problem are a definition and comparability of elements being communicated. The US Geological Survey, with the co-operation of the US Bureau of Mines and the US Department of Energy, has devised a classification system for all mineral resources, the principles of which, it is felt, offer the possibility of world communication. At present several other systems, extant or under development (Potential Gas Committee of the USA, United Nations Resource Committee, and the American Society of Testing and Materials) are internally consistent and provide easy communication linkage. The system in use by the uranium community in the United States of America, however, ties resource quantities to forward-cost dollar values rendering them inconsistent with other classifications and therefore not comparable. This paper develops the rationale for the new USGS resource classification and notes its benefits relative to a forward-cost classification and its relationship specifically to other current classifications.

  19. Factors Contributing to Personal Commitment in Chinese Interethnic Couples

    2014-06-01

    Full Text Available Interethnic relationships are increasingly common in many societies, yet interethnic couples have a higher divorce rate compared to intraethnic couples. Given these facts and the dearth of research, this study aimed to identify factors that contribute to couples’ commitment in interethnic relationships. This study investigated the personal commitment of Chinese interethnic couples in the United Kingdom and the United States. Specifically, whether love, dyadic adjustment and “couple cultural identity” (i.e. acculturation to the partner and couple’s similarity on individualism/collectivism would predict personal commitment and whether each variable would account for unique variance in personal commitment of the participants. Thirty-seven Chinese/non-Chinese heterosexual couples participated in the study and significant relationships between love and personal commitment, dyadic adjustment and personal commitment were found. Also, couple cultural identity was important for women’s personal commitment. Multiple regression and structural equation modelling showed that partners in interethnic relationships defined personal commitment in different ways with men emphasizing love and dyadic adjustment, and women emphasizing love and acculturation to their partner. The discovery of the importance of couple cultural identity in contributing to personal commitment, besides love and dyadic adjustment, helps researchers to gain a greater understanding of such relationships and to extend the research on interethnic relationships.

  1. Short Rotation Crops in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Wright, L L

    1998-06-04

    The report is based primarily on the results of survey questions sent to approximately 60 woody and 20 herbaceous crop researchers in the United States and on information from the U.S. Department of Energy's Bioenergy Feedstock Development Program. Responses were received from 13 individuals involved in woody crops research or industrial commercialization (with 5 of the responses coming from industry). Responses were received from 11 individuals involved in herbaceous crop research. Opinions on market incentives, technical and non-technical barriers, and highest priority research and development areas are summarized in the text. Details on research activities of the survey responders are provided as appendices to the paper. Woody crops grown as single-stem systems (primarily Populus and Eucalyptus species) are perceived to have strong pulp fiber and oriented strand board markets, and the survey responders anticipated that energy will comprise 25% or less of the utilization of single-stem short-rotation woody crops between now and 2010. The only exception was a response from California where a substantial biomass energy market does currently exist. Willows (Salix species) are only being developed for energy and only in one part of the United States at present. Responses from herbaceous crop researchers suggested frustration that markets (including biomass energy markets) do not currently exist for the crop, and it was the perception of many that federal incentives will be needed to create such markets. In all crops, responses indicate that a wide variety of research and development activities are needed to enhance the yields and profitability of the crops. Ongoing research activities funded by the U.S. Department of Energy's Bioenergy Feedstock Development Program are described in an appendix to the paper.

  2. Fires Across the Western United States

    Science.gov (United States)

    2007-01-01

    Days of record heat made the western United States tinder dry in early July 2007. Numerous wildfires raced across the dry terrain during the weekend of July 7. From Washington to Arizona, firefighters were battling fast-moving wildfires that threatened residences, businesses, gas wells, coal mines, communications equipment, and municipal watersheds. This image of the West was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite on Sunday, July 8. Places where MODIS detected actively burning fires are marked in red. Some of the largest blazes are labeled. Utah's Milford Flat was the largest; according to the July 9 morning report from the National Interagency Fire Center, the blaze was more than 280,000 acres, having grown more than 124,000 acres in the previous 24 hours. The fires have destroyed homes, forced evacuations, shut down trains and highways, and killed several people. Weather conditions were not expected to improve significantly across much of the area for several days, with hot temperatures and dry thunderstorms (lightning and winds, but little rain) likely in many places. Nearly the entire western United States was experiencing some level of drought as of July 3, according to the U.S. Drought Monitor. The drought had reached the 'extreme' category in southern California and western Arizona, and ranged from moderate to severe across most of the rest of the Southwest and Great Basin. The large image provided above has a spatial resolution (level of detail) of 500 meters per pixel. The MODIS Rapid Response Team provides twice-daily images of the region in additional resolutions and formats, including an infrared-enhanced version that makes burned terrain appear brick red.

  3. The United States: breakthroughs and waste.

    Reinhardt, U E

    1992-01-01

    The health system of the United States is in a paradoxical position. At its best, the system is a magnet for those seeking the latest technical breakthroughs. It can offer that excellence because there have never been effective financial constraints on the imagination; the system has become a major economic frontier, at which professional and other entrepreneurs successfully seek their fortune. At the same time, the system is leaving increasing numbers of Americans frustrated and disillusioned. It is beset by excess capacity in many areas, is needlessly expensive, and often bestows unnecessary health services. Yet only the experts are aware of these flaws; most Americans still express high satisfaction with the quality of the services they receive from their doctors and hospitals. The public's major misgivings arise over the awkward and inequitable way in which American health care is financed. The typical private health insurance policy, for example, is tied to a particular job. If the job is lost, so is the health insurance. Furthermore, these policies are priced on actuarially "fair" principles, so sick individuals are forced to pay higher insurance premiums than relatively healthy ones and chronically ill persons often cannot obtain health insurance coverage at any price. Although there are public programs to catch many persons not privately insured, the coverage tends to be insufficiently extensive and deep. Some 35 million Americans, mostly poor, have no health insurance whatsoever. Unfortunately, at this time there is no political force in the United States strong enough to reform the American health system toward greater social equity and economic efficiency, whereas there are numerous groups powerful enough to block whatever reform might harm their own narrow economic interests. Other nations can learn from America's clinical and organizational innovations in health care delivery. They can also learn what not to do by studying the unseemly way in which

  4. Eye on China and United States

    Full Text Available United States strives to force the Chinese into agreement of increasing the value of their exchange rate to help the USA avoid inflation As China did not come into an agreement with the USA, Tariffs are being put on Chinese products entering USA. However China as began to add tariff on poultry received from the US as well. China was previously not named in the legislation permitting US to add tariff on their goods. But recently a bill was passed giving the commerce department the ability to place important tariffs on all countries to undervalue their currency. The bill passed in legislation had the support of 99 republicans. China has been managing their currency in a manner that makes their goods cheaper to sell and American goods more expensive. The Chinese manipulation of their currency has been quite expensive for the USA, as it has cost them $1.5 billion jobs increasing the percentage of unemployment greatly and significantly. This imposition of tariffs on Chinese goods could result in effecting $300 billion dollars worth of their products. It is obvious that the Americans are attempting to improve and acknowledge their growth and power. As predictions have developed over this conflict, arguing the fact that China will not negotiate with the USA at this point rather fight back and also approach in adding tariffs on USimports. However, this reaction by the Chinese will only worsen the scenario and result in the possible inflation of the US economy or worldwide trade war. This is a very sensitive time for the United States as their biggest hopes are dependent on the Chinese. But it doesn’t look like they will be too satisfied with the outcome.

    From 1980 through 1991, the number of legal induced abortions reported to CDC remained stable, varying each year by 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. In 1991, 1,388,937 abortions were reported--a 2.8% decrease from 1990. The abortion ratio was 339 legal induced abortions per 1,000 live births, and the abortion rate was 24 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and had been obtaining an abortion for the first time. More than half (52%) of all abortions were performed at or before the 8th week of gestation, and 88% were before the 13th week. Younger women (i.e., women may partially account for this decline. An accurate assessment of the number and characteristics of women who obtain abortions in the United States is necessary both to monitor efforts to prevent unintended pregnancy and to identify and reduce preventable causes of morbidity and mortality associated with abortions.

    1981-06-01

    In 1980 US buyers contracted for 12,500 short tons U 3 O 8 in new procurement. Nontheless, there was a net decrease of 13,100 tons in total commitments as of January 1, 1981, because of even larger changes to the delivery commitments as of January 1, 1980. The average contract price of domestic uranium was $28.15 per pound of U 3 O 8 for 1980 delivery and $30.70 for 1981 delivery. Settlements of domestic market price contracts averaged $36.75 for 1980 delivery and $46.80 for 1981 delivery. Prices of foreign uranium averaged $43.10 for 1980 delivery and $40.00 for 1981 delivery. Producers expect to be able to offer 21,800 tons U 3 O 8 for sale in the 1981 to 1985 period, about 30 percent less than was estimated in the 1980 survey. US producers also estimated that 30,600 tons U 3 O 8 would be available for sale in the 1986 to 1990 period. Utilities made sales of 800 tons U 3 O 8 for 1980 to 1981 delivery as well as loans of another 800 tons. New export commitments made in 1980 totalled 4000 tons U 3 O 8 ; however, 2500 tons of these commitments are options or delivery is contingent on price developments. Import commitments made in 1980 totalled 2300 tons U 3 O 8 . Inventories of natural and enriched uranium held by US buyers increased from 52,300 to 63,400 tons U 3 O 8 during 1980. In addition, inventories of uranium held by US producers increased from 2400 to 2700 tons U 3 O 8 . Unfilled requirements for the 1981 to 1990 period decreased from 75,300 tons U 3 O 8 , as reported in last year's survey, to 54,500 tons in this year's survey, a decrease of 20,800 tons. Responses to the 1981 survey suggest that there seems to be an adequate supply of uranium to meet US demand at least through 1986, although the apparent buyer requirements reported as of January 1, 1981 for the 1987 to 1990 period are higher than the total domestic production or supply

    For some parts of the Nation, large-scale development of groundwater has caused decreases in the amount of groundwater that is present in aquifer storage and that discharges to surface-water bodies. Water supply in some areas, particularly in arid and semiarid regions, is not adequate to meet demand, and severe drought is affecting large parts of the United States. Future water demand is projected to heighten the current stress on groundwater resources. This combination of factors has led to concerns about the availability of freshwater to meet domestic, agricultural, industrial, mining, and environmental needs. To ensure the water security of the Nation, currently [2016] untapped water sources may need to be developed.Brackish groundwater is an unconventional water source that may offer a partial solution to current and future water demands. In support of the national census of water resources, the U.S. Geological Survey completed the national brackish groundwater assessment to better understand the occurrence and characteristics of brackish groundwater in the United States as a potential water resource. Analyses completed as part of this assessment relied on previously collected data from multiple sources; no new data were collected. Compiled data included readily available information about groundwater chemistry, horizontal and vertical extents and hydrogeologic characteristics of principal aquifers (regionally extensive aquifers or aquifer systems that have the potential to be used as a source of potable water), and groundwater use. Although these data were obtained from a wide variety of sources, the compiled data are biased toward shallow and fresh groundwater resources; data representing groundwater that is at great depths and is saline were not as readily available.One of the most important contributions of this assessment is the creation of a database containing chemical characteristics and aquifer information for the known areas with brackish groundwater

  9. Is a Break with Egalitarian Commitment Necessary to Sustain Europe's Welfare State?

    2016-01-01

    Full Text Available Collectivist values, based on the ideas of egalitarian social compromise have been basic to the construction of the Welfare State, but today tend to break. Immigration and population heterogeneity thus hinder the identifi cation of citizens with collective values. By contrast, emerging new values based on individual merit, which tends to generate a polarization of attitudes. For those profi les that have been the traditional working class, the social closure is a defence mechanism against competition for redistribution, which is refl ected in negative views toward immigration. For those who make up the middle class, high level of education, high income and upper middle position, opinion on immigration and demand for solidarity is not a preferred option because they rely on the success of their individual trajectories.

  10. United States electric industry : restructuring in review

    Slocum Hollis, S.

    2004-01-01

    This paper provides a detailed review of the United States electric power industry. The aim of the review was to clarify and better define current industry procedures and practices in light of significant and recent restructuring. In addition, recent bankruptcies and the power blackout in 2003 have raised concerns over industry practices. Issues concerning Independent System Operators (ISO) and regional transmission organizations were evaluated, with reference to an evolution and implementation of Regional Transmission Organization (RTO) policy, including a cost-benefit analysis. A background of RTO formations was provided with reference to consolidation, selection process and transfer of assets. Standard market design, network access and pricing issues were reviewed, as well as market and reliability concerns. Issues concerning affiliate treatment, shortages and the effect of sale of securities were presented. Various approaches to congestion management were examined, with examples from California and New England. Market monitoring issues, investigations and hearings were also examined, with examples and orders, including details of refunds. Measures to improve reliability were reviewed, including: management systems, benefit margins, requirements, assurance agreements and reserve markets. Issues concerning information access were presented, including: Open Access Same-time Information System (OASIS) requirements; tagging; standard business practices and protocols; and quarterly report practices and protocols. Interconnection policies were reviewed with reference to applicability, service options and pricing. The issue of variations was examined, with case examples concerning cost allocation, contract rights and treatment of specific costs. Jurisdiction issues concerning corporate realignments and power exchanges were presented, as well as specific services and state-federal relations. Issues concerning mergers and merger policy were also discussed, with reference

    Current intended nationally determined contributions (INDCs) are insufficient to meet the Paris Agreement goal of limiting temperature change to between 1.5 and 2.0 °C above pre-industrial levels, so the effectiveness of existing INDCs will be crucial to further progress. Here we assess the likely range of US greenhouse gas (GHG) emissions in 2025 and whether the US’s INDC can be met, on the basis of updated historical and projected estimates. We group US INDC policies into three categories reflecting potential future policies, and model 17 policies across these categories. With all modelled policies included, the upper end of the uncertainty range overlaps with the 2025 INDC target, but the required reductions are not achieved using reference values. Even if all modelled policies are implemented, additional GHG reduction is probably required; we discuss several potential policies.

    In 1979 US buyers contracted for a net increase of 15,400 tons U 3 O 8 in new procurement after deducting for changes to January 1, 1979, commitments. Export commitments made in 1979 totalled 2800 tons, while import commitments amounted to 1000 tons U 3 O 8 . Buyers' inventories of domestic- and foreign-origin normal and enriched uranium increased to 52,300 tons U 3 O 8 during 1979, with the larger part of the increase being in enriched uranium. The average price reported for 1979 deliveries was $23.85 per pound of U 3 O 8 . Settlements of market price contracts average $42.55 for 1979 delivery and $45.80 for 1980 delivery. Producers expect to be able to offer 33,700 tons U 3 O 8 for sale in the 1980-1985 period, about 20% less than was estimated in the 1979 survey. Utilities made sales of 500 tons U 3 O 8 for 1979-1980 delivery as well as loans of 1600 tons U 3 O 8 that are to be repaid by 1984; more than half of these sales or loans were made to uranium producers. Reactor manufacturers have sold about 1100 tons U 3 O 8 since January 1, 1979, and loaned 120 tons. Unfilled requirements have decreased more than 100,000 tons U 3 O 8 since January 1, 1978, and currently total 75,700 tons U 3 O 8 . Responses to the 1980 survey suggest that there seems to be an adequate supply of uranium to meet US demand at least through 1985

    1998-12-01

    Wholesale trade in electricity plays an important role for the US electric utility industry. Wholesale, or bulk power, transactions allow electric utilities to reduce power costs, increase power supply options, and improve reliability. In 1996, the wholesale trade market totaled 2.3 trillion kilowatthours, over 73% of total sales to ultimate consumers. This publication, Electric Trade in the United States 1996 (ELECTRA), is the sixth in a series of reports on wholesale power transactions prepared by the Office of Coal, Nuclear, Electric and Alternate Fuels, Energy Information Administration (EIA). The electric trade data are published biennially. The first report presented 1986 data, and this report provides information on the electric power industry during 1996. The electric trade data collected and presented in this report furnish important information on the wholesale structure found within the US electric power industry. The patterns of interutility trade in the report support analyses of wholesale power transactions and provide input for a broader understanding of bulk power market issues that define the emerging national electric energy policies. The report includes information on the quantity of power purchased, sold, exchanged, and wheeled; the geographical locations of transactions and ownership classes involved; and the revenues and costs. 1 fig., 43 tabs.

    The Federal Geographic Data Committee (FGDC) Vegetation Subcommittee, the Ecological Society of America Panel on Vegetation Classification, and NatureServe have worked together to develop the United States National Vegetation Classification (USNVC). The current standard was accepted in 2008 and fosters consistency across Federal agencies and non-federal partners for the description of each vegetation concept and its hierarchical classification. The USNVC is structured as a dynamic standard, where changes to types at any level may be proposed at any time as new information comes in. But, because much information already exists from previous work, the NVC partners first established methods for screening existing types to determine their acceptability with respect to the 2008 standard. Current efforts include a screening process to assign confidence to Association and Group level descriptions, and a review of the upper three levels of the classification. For the upper levels especially, the expectation is that the review process includes international scientists. Immediate future efforts include the review of remaining levels and the development of a proposal review process.

    Six multichannel seismic-reflection profiles taken across the Atlantic continental margin off the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin. Beneath the continental rise, the sedimentary prism thickness exceeds 7 km south of New Jersey and Maryland, and it is 4.5 km thick south of Georges Bank Stratigraphically, the continental slope--outer edge of the continental shelf is a transition zone of high-velocity sedimentary rock, probably carbonate, that covers deeply subsidized basement. The spatial separation of magnetic and gravity anomalies on line 2 (New Jersey) suggests that in the Baltimore Canyon region the magnetic-slope anomaly is due to edge effects and that the previously reported free-air and isostatic gravity anomalies over the outer shelf may be due in part to a lateral increase in sediment density (velocity) near the shelf edge. The East Coast magnetic anomaly and the free-air gravity high both coincide over the outer shelf edge on line 1 (Georges Bank) but are offset by 20 km from the ridge on the reflection profile

    Physical/semi-empirical models that do not require any calibration are of paramount need for estimating hydrological fluxes for ungauged sites. We develop semi-empirical models for estimating the mean and variance of the monthly streamflow based on Taylor Series approximation of a lumped physically based water balance model. The proposed models require mean and variance of monthly precipitation and potential evapotranspiration, co-variability of precipitation and potential evapotranspiration and regionally calibrated catchment retention sensitivity, atmospheric moisture uptake sensitivity, groundwater-partitioning factor, and the maximum soil moisture holding capacity parameters. Estimates of mean and variance of monthly streamflow using the semi-empirical equations are compared with the observed estimates for 1373 catchments in the continental United States. Analyses show that the proposed models explain the spatial variability in monthly moments for basins in lower elevations. A regionalization of parameters for each water resources region show good agreement between observed moments and model estimated moments during January, February, March and April for mean and all months except May and June for variance. Thus, the proposed relationships could be employed for understanding and estimating the monthly hydroclimatology of ungauged basins using regional parameters.

    Although the popular North American opinion of Mexico is one that paints a picture of a poor, disadvantaged country, South America sees Mexico has a richer more prosperous nation. It is observed that only in the Latin American countries of Venezuela, Suriname and Trinidad and Tobago do consumers have higher incomes than Mexican consumers. Moreover, while millions of Mexicans migrate to the United States to seek a better standard of living, several thousand Central American refugees illegally migrate to Mexico in search of a better life. This better life includes an increased age of lie expectancy from 51 years in the 1950s to 64 years in the late 1970s. There have also been improvements in health care and school enrollments and in the low cost availability of education. Tourism and the prospect of the manufacturing of energy are significant, positive factors working in favor of an improved Mexican economy and a higher overall quality of life. However, Mexico faces serious problems such as a mounting foreign debt. Also rising is Mexico's population which has doubled since 1964 and which continues to grow at a rate of 1.9%. Economic programs and reforms and family development planning have been instituted in response to the countries' current recession and population growth and have begun to show positive results.

    In this paper, we use the locally flexible translog functional form to investigate the demand for energy and interfuel substitution in the United States and to provide a comparison of our results with most of the existing empirical energy demand literature. Motivated by the widespread practice of ignoring theoretical regularity, we follow Barnett's (2002) suggestions and estimate the model subject to theoretical regularity, using methods developed by Diewert and Wales (1987) and Ryan and Wales (2000), in an attempt to produce inference consistent with neoclassical microeconomic theory. Moreover, we use the most recent data, published by the U.S. Energy Information Administration (EIA), and in addition to investigating interfuel substitution possibilities in total U.S. energy demand, we follow Serletis et al. (2009) and also examine interfuel substitution possibilities in energy demand by sector. Moreover, we test for weak separability, with the objective of discovering the structure of the functional form in total energy demand as well as energy demand by sector. (author)

  4. 2011 floods of the central United States

    The Central United States experienced record-setting flooding during 2011, with floods that extended from headwater streams in the Rocky Mountains, to transboundary rivers in the upper Midwest and Northern Plains, to the deep and wide sand-bedded lower Mississippi River. The U.S. Geological Survey (USGS), as part of its mission, collected extensive information during and in the aftermath of the 2011 floods to support scientific analysis of the origins and consequences of extreme floods. The information collected for the 2011 floods, combined with decades of past data, enables scientists and engineers from the USGS to provide syntheses and scientific analyses to inform emergency managers, planners, and policy makers about life-safety, economic, and environmental-health issues surrounding flood hazards for the 2011 floods and future floods like it. USGS data, information, and scientific analyses provide context and understanding of the effect of floods on complex societal issues such as ecosystem and human health, flood-plain management, climate-change adaptation, economic security, and the associated policies enacted for mitigation. Among the largest societal questions is "How do we balance agricultural, economic, life-safety, and environmental needs in and along our rivers?" To address this issue, many scientific questions have to be answered including the following: * How do the 2011 weather and flood conditions compare to the past weather and flood conditions and what can we reasonably expect in the future for flood magnitudes?

  5. United States Holocaust Museums: Pathos, Possession, Patriotism

    2011-12-01

    Full Text Available This article examines the role of United States holocaust museums in directing (American knowledge and memory of World War II, and demonstrates how signifiers of race, colour and Jewishness are played out and theatricalised. Erected in two principal U.S. cities of Los Angeles and Washington, D.C., the Holocaust Museum and Museum of Tolerance uphold very different mandates: the first dedicated to revealing European civilian tragedies during WWII; the latter dealing with Jewish persecution and the L.A. Riots of 1991, with references to other cultural catastrophes. While these projects are different, they are not opposed; both museums locate the American perspective of events and their meanings at the forefront. American holocaust museums seem to challenge spaces between memory and its direction, vision and revision. Within the gruesome context of holocaust portrayal, interrogate the valences of memory’s play and expose American holocaust museums as theatres of pornographic memory. The seduction of feeling does not invite change so much as purgation, what Aristotle identified as catharsis — an emotional and physical release, unfortunately replicating the seductive techniques used by Goebbels for the glorification of Hitler. Through manipulation of viewers as automatic audiences, these museums function as centres for pathos I question the policy and polity of presenting genocide as an entertainment leading to catharsis, recognizing that the final act of purgation is all too easily negation.

    Background Descriptive epidemiologic studies of recurrent and non-recurrent Kawasaki disease (KD) may identify other potentially important differences between these illnesses. Methods Data from the United States and Japan, the Centers for Disease Control and Prevention (CDC) national KD surveillance (1984–2008) and the 17th Japanese nationwide survey (2001–2002), respectively, were analyzed to examine recurrent KD patients <18 years of age meeting the CDC KD case or atypical KD case definition. These patients were compared to non-recurrent KD patients. Results Of the 5557 US KD patients <18 years of age during 1984–2008, 97 (1.7%) were identified as having had recurrent KD. Among the US Asian/Pacific Islander KD patients, 3.5% had recurrent KD, which was similar to the percentage identified among KD patients (3.5%) in the Japanese survey. Compared to non-recurrent KD patients, KD patients experiencing a recurrent KD episode were more likely to be older, fulfill the atypical KD case definition, and have coronary artery abnormalities (CAA) despite IVIG treatment. Conclusions Differences in the age, race, and frequency of CAA exist between recurrent and non-recurrent KD patients. The increased association of CAA with recurrent KD suggests that more aggressive treatment strategies in conjunction with IVIG may be indicated for the second episode of KD. PMID:26096590

    Convectively generated wind-storms occur over broad temporal and spatial scales; however, the more widespread and longer lived of these windstorms have been given the name "derecho." Utilizing an integrated derecho database, including 377 events from 1986 to 2003, this investigation reveals the amount of insured property losses, fatalities, and injuries associated with these windstorms in the United States. Individual derechos have been responsible for up to 8 fatalities, 204 injuries, forest blow-downs affecting over 3,000 km2 of timber, and estimated insured losses of nearly a $500 million. Findings illustrate that derecho fatalities occur more frequently in vehicles or while boating, while injuries are more likely to happen in vehicles or mobile homes. Both fatalities and injuries are most common outside the region with the highest derecho frequency. An underlying synthesis of both physical and social vulnerabilities is suggested as the cause of the unexpected casualty distribution. In addition, casualty statistics and damage estimates from hurricanes and tornadoes are contrasted with those from derechos to emphasize that derechos can be as hazardous as many tornadoes and hurricanes.

    The U.S. Geological Survey seismic hazard maps for the central and eastern United States were updated in 2014. We analyze results and changes for the eastern part of the region. Ratio maps are presented, along with tables of ground motions and deaggregations for selected cities. The Charleston fault model was revised, and a new fault source for Charlevoix was added. Background seismicity sources utilized an updated catalog, revised completeness and recurrence models, and a new adaptive smoothing procedure. Maximum-magnitude models and ground motion models were also updated. Broad, regional hazard reductions of 5%–20% are mostly attributed to new ground motion models with stronger near-source attenuation. The revised Charleston fault geometry redistributes local hazard, and the new Charlevoix source increases hazard in northern New England. Strong increases in mid- to high-frequency hazard at some locations—for example, southern New Hampshire, central Virginia, and eastern Tennessee—are attributed to updated catalogs and/or smoothing.

  9. DOE and the United States enrichment market

    The US Department of Energy (DOE) and its predecessors have exerted a predominant influence in the uranium enrichment services industry since 1969, when it began to sell its services to private industry under a Requirement-Type Contract (RTC). After almost 25 years of providing these services to utilities throughout the world, DOE is now preparing to hand over responsibility to the emerging US Enrichment Corporation (USEC), which was created by the 1992 Energy Bill and will begin its tenure on July 1, 1993. DOE has had some notable successes, including revenue generation of about $25 billion from its domestic and foreign sales since 1969. Annual revenues from civilian dollars over the next several years. However, most of the sales attributed to these revenues took place in 1986-more than six years ago. Presently, US utility commitments are decreasing significantly; to date, US utilities have committed less than two percent of their total FY2002 enrichment requirements to DOE. In spite of the fact that DOE has enjoyed some success, its past actions, or sometimes inactions, have often been steeped in controversy that resulted in customer alienation and dissatisfaction. It is the legacy of past DOE contracting practices, increased competition, and massive contractual terminations, that USEC will inherit from DOE. Therefore, it is relevant to consider the major issues that have fashioned the current US market and resulted in USEC's initial position in the marketplace

  10. Considerations in civil commitment of individuals with substance use disorders.

    Several states currently have enacted laws that allow for civil commitment for individuals diagnosed with severe substance use disorders. Civil commitment or involuntary commitment refers to the legal process by which individuals with mental illness are court-ordered into inpatient and/or outpatient treatment programs. Although initially civil commitment laws were intended for individuals with severe mental illness, these statutes have been extended to cover individuals with severe substance use disorders. Much of the recent legislation allowing for civil commitment of individuals with substance use disorders has come about in response to the heroin epidemic and is designed to provide an alternative to the unrelenting progression of opioid use disorders. Civil commitment also provides an opportunity for individuals with opioid use disorders to make informed decisions regarding ongoing or continued treatment. However, civil commitment also raises concerns regarding the potential violation of 14th Amendment rights, specifically pertaining to abuses of deprivation of liberty or freedom, which are guaranteed under the 14th Amendment to the United States Constitution. This commentary examines these issues while supporting the need for effective brief civil commitment legislation in all states.

    Full Text Available To gauge the current commitment to scientific research in the United States of America (US, we compared federal research funding (FRF with the US gross domestic product (GDP and industry research spending during the past six decades. In order to address the recent globalization of scientific research, we also focused on four key indicators of research activities: research and development (R&D funding, total science and engineering doctoral degrees, patents, and scientific publications. We compared these indicators across three major population and economic regions: the US, the European Union (EU and the People's Republic of China (China over the past decade. We discovered a number of interesting trends with direct relevance for science policy. The level of US FRF has varied between 0.2% and 0.6% of the GDP during the last six decades. Since the 1960s, the US FRF contribution has fallen from twice that of industrial research funding to roughly equal. Also, in the last two decades, the portion of the US government R&D spending devoted to research has increased. Although well below the US and the EU in overall funding, the current growth rate for R&D funding in China greatly exceeds that of both. Finally, the EU currently produces more science and engineering doctoral graduates and scientific publications than the US in absolute terms, but not per capita. This study's aim is to facilitate a serious discussion of key questions by the research community and federal policy makers. In particular, our results raise two questions with respect to: a the increasing globalization of science: "What role is the US playing now, and what role will it play in the future of international science?"; and b the ability to produce beneficial innovations for society: "How will the US continue to foster its strengths?"

    Multilocus DNA sequence data were used to assess the genetic diversity and evolutionary relationships of 67 Fusarium strains from veterinary sources, most of which were from the United States. Molecular phylogenetic analyses revealed that the strains comprised 23 phylogenetically distinct species, all but two of which were previously known to infect humans, distributed among eight species complexes. The majority of the veterinary isolates (47/67 = 70.1%) were nested within the Fusarium solani species complex (FSSC), and these included 8 phylospecies and 33 unique 3-locus sequence types (STs). Three of the FSSC species (Fusarium falciforme, Fusarium keratoplasticum, and Fusarium sp. FSSC 12) accounted for four-fifths of the veterinary strains (38/47) and STs (27/33) within this clade. Most of the F. falciforme strains (12/15) were recovered from equine keratitis infections; however, strains of F. keratoplasticum and Fusarium sp. FSSC 12 were mostly (25/27) isolated from marine vertebrates and invertebrates. Our sampling suggests that the Fusarium incarnatum-equiseti species complex (FIESC), with eight mycoses-associated species, may represent the second most important clade of veterinary relevance within Fusarium Six of the multilocus STs within the FSSC (3+4-eee, 1-b, 12-a, 12-b, 12-f, and 12-h) and one each within the FIESC (1-a) and the Fusarium oxysporum species complex (ST-33) were widespread geographically, including three STs with transoceanic disjunctions. In conclusion, fusaria associated with veterinary mycoses are phylogenetically diverse and typically can only be identified to the species level using DNA sequence data from portions of one or more informative genes.

  16. Homicides - United States, 2007 and 2009.

    Science.gov (United States)

    Logan, Joseph E; Hall, Jeffrey; McDaniel, Dawn; Stevens, Mark R

    2013-11-22

    According to 1981-2009 data, homicide accounts for 16,000-26,000 deaths annually in the United States and ranks within the top four leading causes of death among U.S. residents aged 1-40 years. Homicide can have profound long-term emotional consequences on families and friends of victims and on witnesses to the violence, as well as cause excessive economic costs to residents of affected communities. For years, homicide rates have been substantially higher among certain populations. Previous reports have found that homicides are higher among males, adolescents and young adults, and certain racial/ethnic groups, such as non-Hispanic blacks, non-Hispanic American Indian/Alaska Natives (AI/ANs), and Hispanics. The 2011 CDC Health Disparities and Inequalities Report (CHDIR) described similar findings for the year 2007. For example, the 2011 report showed that the 2007 homicide rate was highest among non-Hispanic blacks (23.1 deaths per 100,000), followed by AI/ANs (7.8 deaths per 100,000), Hispanics (7.6 deaths per 100,000), non-Hispanic whites (2.7 deaths per 100,000), and Asian/Pacific Islanders (A/PIs) (2.4 deaths per 100,000). In addition, non-Hispanic black men aged 20-24 years were at greatest risk for homicide in 2007, with a rate that exceeded 100 deaths per 100,000 population. Other studies have reported that community factors such as poverty and economic inequality and individual factors such as unemployment and involvement in criminal activities can play a substantial role in these persistent disparities in homicide rates. Public health strategies are needed in communities at high risk for homicide to prevent violence and save lives.

    The 1977 survey requested data on U purchase commitments, U imports and exports, reactor fuel arrangements and unfilled requirements, inventories of domestic and foreign U, and prices for existing contracts between producers and buyers. The 207 U.S. power reactors in operation, under construction, or for which orders have been placed, are covered. Information was received from 70 utilities, 38 present or potential U producers, and 5 reactor manufacturers. Net additional procurement is 83,400 tons of U 3 O 8 , with direct involvement of the purchasers in almost half the cases. During 1976, average U prices increased substantially for 1976-77 and 1980-85 deliveries, but only minor changes for 1978 and 1979. Average delivery prices remain well below prices for new procurement. 12 tables, 7 figs

    Objectives. In the United States, state firearm ownership has been correlated with homicide rates. More than 90% of homicides of law enforcement officers (LEOs) are committed with firearms. We examined the relationship between state firearm ownership rates and LEO occupational homicide rates. Methods. We obtained the number LEOs killed from 1996 to 2010 from a Federal Bureau of Investigation (FBI) database. We calculated homicide rates per state as the number of officers killed per number of LEOs per state, obtained from another FBI database. We obtained the mean household firearm ownership for each state from the Behavioral Risk Factor Surveillance System. Results. Using Poisson regression and controlling for factors known to affect homicide rates, we associated firearm ownership with the homicide rates for LEOs (incidence rate ratio = 1.044; P = .005); our results were supported by cross-sectional and longitudinal sensitivity analyses. LEO homicide rates were 3 times higher in states with high firearm ownership compared with states with low firearm ownership. Conclusions. High public gun ownership is a risk for occupational mortality for LEOs in the United States. States could consider methods for reducing firearm ownership as a way to reduce occupational deaths of LEOs. PMID:26270316

    Given the steady rise of psychiatric coercive measures in Germany, the question arises whether this development is significantly influenced by the corresponding legal basis or through epidemiological, socio-economic or socio-structural factors. Based on full surveys of the Federal Ministry of Justice we examined the development and associations of 10 indicators of coercive psychiatric measures over a period of 18 years. Time trends of all indicators have been descriptively analysed. Statistical associations between time trends and between involuntary and admissions economic indicators were analysed by regression models. All annual involuntary commitment rates have increased, judicial ordered physical restraint measures particularly strongly (848%). The rate of judicial rejections of applied involuntary measures showed the lowest increase. On the other hand, quotas of involuntary admissions remained stable. In former East Germany, the involuntary admission rates are only a third of those in the former West Germany. Results of regression analyses indicate an excess increase of physical coercive measures in psychiatric hospitals in relation to the increase of psychiatric admissions. In former East Germany the rate of involuntary admissions at the federal state level is negatively correlated with the average gross income. The continuous increase of coercive psychiatric measures in consequence to the change in the Guardianship law suggests that this change has influenced the practice. The differences at federal and state levels, and the sharper rise in the former East Germany by lower rates in comparison to the former West Germany need an explanation, as well as the fact that the rate of involuntary admissions is associated at least in the former East Germany with economic conditions. © Georg Thieme Verlag KG Stuttgart · New York.

    1997-01-01

    Through the combined efforts of the United States and many other nations participating in the Reduced Enrichment for Research and Test Reactors (RERTR) program, much progress has been made toward reducing the amount of highly enriched uranium (HEU) in international commerce. A little more than a year ago, the U.S. Department of Energy adopted a new 1 0-year policy to accept research reactor spent nuclear fuel into the United States from other nations. The policy supports U.S. nuclear weapons nonproliferation objectives and demonstrates the continued commitment of the U.S. to the RERTR program. This paper is a review of the past year's activities and addresses the progress made since the policy was implemented

    Geothermal energy is used for electric power generation and direct utilization in the United States. The present installed capacity (gross) for electric power generation is 2,534 MWe with about 2,000 MWe net delivering power to the grid producing approximately 17,840 GWh per year for a 80.4% gross capacity factor. Geothermal electric power plants are located in California, Nevada, Utah and Hawaii. The two largest concentrations of plants are at The Geysers in northern California and the Imperial Valley in southern California. The latest development at The Geysers, starting in 1998, is injecting recycled wastewater from two communities into the reservoir, which presently has recovered about 100 MWe of power generation. The second pipeline from the Santa Rosa area has just come on line. The direct utilization of geothermal energy includes the heating of pools and spas, greenhouses and aquaculture facilities, space heating and district heating, snow melting, agricultural drying, industrial applications and groundsource heat pumps. The installed capacity is 7,817 MWt and the annual energy use is about 31,200 TJ or 8,680 GWh. The largest application is ground-source (geothermal) heat pumps (69% of the energy use), and the next largest direct-uses are in space heating and agricultural drying. Direct utilization (without heat pumps) is increasing at about 2.6% per year; whereas electric power plant development is almost static, with only about 70 MWe added since 2000 (there were errors in the WGC2000 tabulation). A new 185-MWe plant being proposed for the Imperial Valley and about 100 MWe for Glass Mountain in northern California could be online by 2007-2008. Several new plants are proposed for Nevada totaling about 100 MWe and projects have been proposed in Idaho, New Mexico, Oregon and Utah. The total planned in the next 10 years is 632 MWe. The energy savings from electric power generation, direct-uses and ground-source heat pumps amounts to almost nine million tonnes

  13. Canada's national report on actions to meet commitments under the United Nations Framework Convention on Climate Change

    International Nuclear Information System (INIS)

    1993-09-01

    Current actions by Canadian governments, non-governmental organizations, communities, and the private sector to meet domestic and international climate change commitments are reviewed. The possible impacts of climate change on Canada are discussed and Canadian greenhouse gas emissions are assessed in terms of factors such as climate, geography, land use, economic structure, and energy production and consumption. Canada's draft National Action Strategy on Global Warming provides a framework for actions to limit greenhouse gas emissions. Measures already taken include those aimed at increasing energy efficiency and energy conservation or encouraging a switch to less carbon-intensive energy sources. Other measures include information and education initiatives, regulation, research and development, and economic instruments. Actions have already been taken in the transportation, electricity generation, residential/commercial, resource/manufacturing industry, and waste management sectors. Canada is also involved in international studies and agreements to limit global greenhouse gas emissions. Four tools are used to assess progress in limiting emissions: emission inventories, climate change indicators, an emissions outlook, and case studies. The emissions outlook presented shows that energy-related greenhouse gas emissions will increase 10.6% from 1990 to 2000, reaching the equivalent of 538.2 megatonnes of CO 2 . A case study shows that current and planned measures to limit greenhouse gas emissions associated with space heating requirements in new single-family homes will reduce emissions in this area 18% from what they would otherwise be in the year 2000. 58 refs., 44 figs., 21 tabs

    Hill, Richard N [Environmental Protection Agency, Washington, DC (United States)

    1992-07-01

    In recognition of potential risks, all pesticides distributed and sold in the United States must fulfil extensive registration requirements for the Environmental Protection Agency (EPA). Registration is a licensing procedure where industry must submit data to demonstrate the safety of pesticidal substances and products before they can be used commercially. The regulatory control of pesticides is unique among chemicals in the U.S. in that testing beyond initial registration may be imposed by the Agency throughout the commercial life of the chemical, as long as there is adequate justification. Registration requirements are gauged to the nature of potential exposures. For instance, more data are generally needed for food use registrations than for non-food uses because of direct consumption of treated foods by the whole U.S. population. Unlike pesticide practices in many countries and authorities, as in the European Community where agricultural pesticides, non-agricultural pesticides and genetically engineered microbial agents are handled by separate directives, all pesticide activities are covered in the U.S. by the Federal Insecticide, Fungicide and Rodenticide Act. This statute covers pesticide uses on foods and animal feed and a number of non-food applications like forest and horticultural uses, residential lawn care, in-home applications, and disinfectants/sterilants. Traditional inorganic and organic chemicals are covered, as well as biological agents like pheromones. Naturally occurring and genetically altered microorganisms also come under the definition of pesticides, but multicellular animals are exempt from regulation as pesticides. Pesticide registration in the U.S. as in many other countries may be a long-term, resource intensive undertaking. Not uncommonly the process from beginning to complete registration may take 4 to 10 years and cost about $10 million.

  4. Model-based investigation of the electricity market. Unit commitment and power plant investments; Modellgestuetzte Untersuchung des Elektrizitaetsmarktes. Kraftwerkseinsatzplanung und -investitionen

    Energy Technology Data Exchange (ETDEWEB)

    Sun, Ninghong

    2013-08-08

    The German Federal Government published its energy concept in September 2010 with a description of the road into the era of renewable energies. Therefore, the future renewable energy installed in Germany is expected to consist mostly of wind and solar, which are subject to intermittency of supply and significant fluctuations. The growing portion of energy generation by fluctuating sources is turning to a big challenge for the power plant unit commitment and the investment decisions as well. In this thesis, a fundamental electricity market model with combined modeling of these two aspects is developed. This model is subsequently applied to the German electricity market to investigate what kind of power plant investments are indispensable, considering the steadily increasing portion of energy generation from fluctuating sources, to ensure a reliable energy supply in a cost-effective way in the future. In addition, current energy policy in Germany regarding the use of renewable energy and nuclear energy is analyzed.

  5. Introduction of Eucalyptus spp. into the United States with Special Emphasis on the Southern United States

    Directory of Open Access Journals (Sweden)

    R. C. Kellison

    2013-01-01

    Full Text Available Introduction of Eucalyptus spp. into the United States from Australia on a significant scale resulted from the gold rush into California in 1849. Numerous species were evaluated for fuel, wood products, and amenity purposes. The first recorded entry of eucalyptus into the southern United Stated was in 1878. Subsequent performance of selected species for ornamental purposes caused forest industry to visualize plantations for fiber production. That interest led the Florida Forestry Foundation to initiate species-introduction trials in 1959. The results were sufficiently promising that a contingent of forest products companies formed a cooperative to work with the USDA Forest Service, Lehigh Acres, FL, USA, on genetic improvement of selected species for fiber production. The Florida initiative caused other industrial forestry companies in the upper South to establish plantations regardless of the species or seed source. The result was invariably the same: failure. Bruce Zobel, Professor of Forestry, North Carolina State University, initiated a concerted effort to assess the potential worth of eucalyptus for plantation use. The joint industrial effort evaluated 569 sources representing 103 species over a 14-year period. The three levels of testing, screening, in-depth, and semioperational trials led to identification of some species and sources that offered promise for adaptation, but severe winter temperatures in late 1983 and early 1984 and 1985 terminated the project. Despite the failed attempt valuable silvicultural practices were ascertained that will be beneficial to other researchers and practitioners when attempts are again made to introduce the species complex into the US South.

    Andrade, Stefan Bastholm; Thomsen, Jens-Peter

    2018-01-01

    An overall finding in comparative mobility studies is that intergenerational mobility is greater in Scandinavia than in liberal welfare-state countries like the United States and United Kingdom. However, in a recent study, Landersø and Heckman (L & H) (2017) argue that intergenerational educational...... mobility in Denmark and the United States is remarkably similar. L & H’s findings run contrary to widespread beliefs and have been echoed in academia and mass media on both sides of the Atlantic Ocean. In this article, we reanalyze educational mobility in Denmark and the United States using the same data...... sources as L & H. We apply several different methodological approaches from economics and sociology, and we consistently find that educational mobility is higher in Denmark than in the United States....

    The electricity system in the United States is a complex mechanism where different technologies, jurisdictions and regulatory designs interact. Today, two major models for electricity commercialization operate in the United States. One is the regulated monopoly model, in which vertically integrated electricity providers are regulated by state commissions. The other is the competitive model, in which power producers can openly access transmission infrastructure and participate in wholesale electricity markets. This paper describes the origins, evolution, and current status of the regulations that enable competitive markets in the United States.

    United States Automotive Materials Partnership

    2011-01-31

    The United States Automotive Materials Partnership LLC (USAMP) was formed in 1993 as a partnership between Chrysler Corporation, Ford Motor Company, and General Motors Corporation. Since then the U.S. Department of Energy (DOE) has supported its activities with funding and technical support. The mission of the USAMP is to conduct vehicle-oriented research and development in materials and materials processing to improve the competitiveness of the U.S. Auto Industry. Its specific goals are: (1) To conduct joint research to further the development of lightweight materials for improved automotive fuel economy; and (2) To work with the Federal government to explore opportunities for cooperative programs with the national laboratories, Federal agencies such as the DOE and universities. As a major component of the DOE's Office of FreedomCAR and Vehicle Technologies Program (FCVT) collaboration with the USAMP, the Automotive Lightweighting Materials (ALM) program focuses on the development and validation of advanced materials and manufacturing technologies to significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. The FCVT was announced in FY 2002 and implemented in FY 2003, as a successor of the Partnership for a New Generation of Vehicles (PNGV), largely addressed under the first Cooperative Agreement. This second USAMP Cooperative Agreement with the DOE has expanded a unique and valuable framework for collaboratively directing industry and government research efforts toward the development of technologies capable of solving important societal problems related to automobile transportation. USAMP efforts are conducted by the domestic automobile manufacturers, in collaboration with materials and manufacturing suppliers, national laboratories, universities, and other technology or trade organizations. These interactions provide a direct route for implementing newly

  20. Disarmament through regional dialogue: United States arms control and disarmament policies

    International Nuclear Information System (INIS)

    Holum, J.D.

    1994-01-01

    Less than fifty years ago, Japan and the United States faced one another in history's deadliest conflict. Since that world war, the competition has been limited to a mature-if spirited-contest for customers. The two countries have become firm friends for peace-and leaders in the international community's campaign against weapons of mass destruction. This friendship is too important to be shaken by momentary upsets. The countries that learned the most from the last great war are today among the most resolutely peaceful in the world. To my mind, it is no coincidence that Japan and Germany, two nations which transformed defeat in that war into remarkable economic success following it-which have sought prosperity and harmony with their neighbours instead of dominion over them-are the two nations the United States would like to see added as permanent members to the United Nations Security Council. There is hope that, some day, countries may be judged not by the arms but the commitments they keep-and the values they uphold. All responsible nations must affirm that nuclear non-proliferation is an enduring value, not a passing policy. United States Arms Control and Disarmament Agency underlines that its highest priority in the coming year is indefinite and unconditional extension of the Non-proliferation Treaty

  1. A Bi-Level Particle Swarm Optimization Algorithm for Solving Unit Commitment Problems with Wind-EVs Coordinated Dispatch

    Song, Lei; Zhang, Bo

    2017-07-01

    Nowadays, the grid faces much more challenges caused by wind power and the accessing of electric vehicles (EVs). Based on the potentiality of coordinated dispatch, a model of wind-EVs coordinated dispatch was developed. Then, A bi-level particle swarm optimization algorithm for solving the model was proposed in this paper. The application of this algorithm to 10-unit test system carried out that coordinated dispatch can benefit the power system from the following aspects: (1) Reducing operating costs; (2) Improving the utilization of wind power; (3) Stabilizing the peak-valley difference.

  2. Residential firewood use in the United States.

    Lipfert, F W; Dungan, J L

    1983-03-25

    An empirical relation between residential firewood use and population density was developed from survey data for 64 counties in New England and was corroborated by data from other states. The results indicate that usage is concentrated in urbanized areas of the Northeast and north central states and that about 9.0 to 11.0 percent of U.S. space heating input is from firewood. No constraints due to the supply of wood were apparent in 1978-1979. These findings have implications for effects on air quality.

    Suttmeier, R.P.

    1980-01-01

    The initiation of a new approach to non-proliferation policy by the United States in 1977 was the most upsetting development in the history of US-Japanese nuclear relations. The policy has seemingly altered Japanese views of its own nuclear future very little, yet it has altered the tone of the nuclear relationship with the United States. Recent Japanese nuclear power developments, both technical and administrative, are outlined and the prospects for the future of the United States-Japanese nuclear relationship and for Pacific regional cooperation assessed. Issues of importance in the relationship include reprocessing - enrichment, plutonium management, spent fuel and waste management and uranium supplies

  7. The World Health Organization Global Health Emergency Workforce: What Role Will the United States Play?

    Science.gov (United States)

    Burkle, Frederick M

    2016-08-01

    During the May 2016 World Health Assembly of 194 member states, the World Health Organization (WHO) announced the process of developing and launching emergency medical teams as a critical component of the global health workforce concept. Over 64 countries have either launched or are in the development stages of vetting accredited teams, both international and national, to provide surge support to national health systems through WHO Regional Organizations and the delivery of emergency clinical care to sudden-onset disasters and outbreak-affected populations. To date, the United States has not yet committed to adopting the emergency medical team concept in funding and registering an international field hospital level team. This article discusses future options available for health-related nongovernmental organizations and the required educational and training requirements for health care provider accreditation.

  10. Co-option and Organisational Survival: A Case Study of the Risks and Opportunities of State Attachment within the United States Feminist Antiviolence Movement

    Directory of Open Access Journals (Sweden)

    Aisha Rios

    2018-03-01

    Full Text Available This article articulates the unstable and contested context of domestic violence advocacy and activism through the experiences of feminist antiviolence professionals working at a quasi-state agency in the southeastern United States. In the context of the NGOization of the antiviolence movement, this agency’s attachment to the state created opportunities to insert marginalized perspectives into the dominant public dialogue on and responses to domestic violence but ultimately facilitated threats against the agency’s entire existence. Organizational survival and a commitment to antiviolence advocacy at the state level led to resistance strategies against state cooption in alignment with neoliberal discourses and practices. State attachment in this context presented ambiguous outcomes for the promotion of feminist, survivor-centered goals, but strategic connections to community-based groups and the criminal justice system presented opportunities for effective resistance against state cooption.

  12. Transmission policy in the United States

    International Nuclear Information System (INIS)

    Joskow, P.L.

    2005-01-01

    This paper provides an overview of the development of electric power transmission access, pricing and investment policies in the US over the last 15 years and evaluates the current state of those policies. Pre-liberalization transmission access and pricing policies are reviewed first since more recent policies have evolved from them. FERC's efforts to ensure that transmission owning utilities provide non-discriminatory access and pricing to wholesale transmission customers, culminating in Order 888 and 889 are discussed. These rules did not respond to problems created by a highly balkanized transmission system and only partially responded to problems caused by common ownership and operation of transmission networks with generating and marketing businesses in the same regions. These problems motivated FERC to seek to create Regional Transmission Organizations (RTO) meeting a long list of criteria related to governance, network operations, transmission pricing and investment as reflected in Order 2000. The slow pace of 'voluntary' reform following Order 2000 led FERC to issue a proposed Standard Market Design Rule (SMD) which provided more detailed prescriptions for wholesale market design, network operations, regional planning, resource adequacy, and transmission investment. The SMD rule confronted enormous resistance from groups of utilities and states that had not embraced an electricity sector liberalization agenda. However, many of the provisions of the SMD are being implemented by the RTOs and ISOs in the Northeast and Midwest. PJM's market rules and transmission pricing, planning and investment policies are reviewed as an articulation of FERC's RTO and SMD visions. (author)
