    2003-01-01

    Natural Resources Canada launched a print advertising campaign and one 30-second television commercial to promote the Energy Star symbol and to acquaint the public with the program that identifies energy efficient products that reduce energy use, save money and reduce greenhouse gas emissions that contribute to climate change. The Communications Branch of Natural Resources Canada wanted to pre-test the television and print ads. Each print ad focused on a particular product category, including home comfort, appliances, electronics and office equipment. The qualitative research methodology was used in the pre-testing because it is the best learning tool for understanding the range and depth of reactions toward a subject at any given time. The findings were not quantifiable because they are not representative of the population at large. Ten focus groups were surveyed in January 2003 in 5 Canadian centres with a total of 83 participants aged 18 to 54. The target groups included people who were informed about climate change issues as well as those who were note. Participants were questioned about the Energy Star Product. Findings were consistent across all 5 locations. There was some general awareness of EnerGuide on appliances in all groups, but generally a low awareness of the Energy Star symbol. Most people did not place energy efficiency as a high priority when purchasing appliances. This report presented the main findings of attitudes towards climate change, Kyoto and energy efficiency. The reaction to the television and print ads was also included along with opinions regarding their main weaknesses and strengths. Some recommendations for improvement were also included. Samples of the print advertisements were included in both English and French. tabs., figs.

    Energy in stars is released partly by gravitation, partly by nuclear reactions. For ordinary stars like our sun, nuclear reactions predominate. However, at the end of the life of a star very large amounts of energy are released by gravitational collapse; this can amount to as much as 10 times the total energy released nuclear reactions. The rotational energy of pulsars is a small remnant of the energy of gravitation. The end stage of small stars is generally a white dwarf, of heavy stars a neutron star of possibly a black hole

  18. Stable dark energy stars

    Lobo, Francisco S N

    The gravastar picture is an alternative model to the concept of a black hole, where there is an effective phase transition at or near where the event horizon is expected to form, and the interior is replaced by a de Sitter condensate. In this work a generalization of the gravastar picture is explored by considering matching of an interior solution governed by the dark energy equation of state, ω ≡ p/ρ < -1/3, to an exterior Schwarzschild vacuum solution at a junction interface. The motivation for implementing this generalization arises from the fact that recent observations have confirmed an accelerated cosmic expansion, for which dark energy is a possible candidate. Several relativistic dark energy stellar configurations are analysed by imposing specific choices for the mass function. The first case considered is that of a constant energy density, and the second choice that of a monotonic decreasing energy density in the star's interior. The dynamical stability of the transition layer of these dark energy stars to linearized spherically symmetric radial perturbations about static equilibrium solutions is also explored. It is found that large stability regions exist that are sufficiently close to where the event horizon is expected to form, so that it would be difficult to distinguish the exterior geometry of the dark energy stars, analysed in this work, from an astrophysical black hole

    Greene, D.L.

    2003-06-24

    The authors of this report, under the sponsorship of the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) Weatherization and Intergovernmental Program, have investigated the possible application of Energy Star ratings to passenger cars and light trucks. This study establishes a framework for formulating and evaluating Energy Star rating methods that is comprised of energy- and environmental-based metrics, potential vehicle classification systems, vehicle technology factors, and vehicle selection criteria. The study tests several concepts and Energy Star rating methods using model-year 2000 vehicle data--a spreadsheet model has been developed to facilitate these analyses. This study tests two primary types of rating systems: (1) an outcome-based system that rates vehicles based on fuel economy, GHG emissions, and oil use and (2) a technology-based system that rates vehicles based on the energy-saving technologies they use. Rating methods were evaluated based on their ability to select vehicles with high fuel economy, low GHG emissions, and low oil use while preserving a full range of service (size and acceleration) and body style choice. This study concludes that an Energy Star rating for passenger cars and light trucks is feasible and that several methods could be used to achieve reasonable tradeoffs between low energy use and emissions and diversity in size, performance, and body type. It also shows that methods that consider only fuel economy, GHG emissions, or oil use will not select a diverse mix of vehicles. Finally, analyses suggest that methods that encourage the use of technology only, may result in increases in acceleration power and weight rather than reductions in oil use and GHG emissions and improvements in fuel economy.

  16. Power performance measurements on Wave Star in Nissum Bredning. Final report; Wave energy converter; Effektmaalinger paa Wave Star i Nissum Bredning. Afsluttende rapport

    Frigaard, P.; Lykke Andersen, T.

    2009-04-15

    The Wave Star test machine in Nissum Bredning was put in continuous operation on 24 July 2006. Over the past 2 1/2 years the produced power was measured continuously and with only minor interruptions. The measurements cover operation for all seasons in a very changeable climate. There is thus gaining operational experience under different wave conditions. In the period the machine has been running with a simple form of control and Power Take Off system (PTO), which form the background for effect measurements with the existing control strategy. Calculations have shown that the use of more advanced forms of control can increase the efficiency of Wave Star significantly. New control systems are therefore still under development with the primary objective to increase performance from the wave energy plant. To test and develop the methods, a new mini-hydraulic station with associated second generation PTO was developed and constructed for testing in Nissum Bredning. The mini-hydraulic station is coupled to a single float, while the other machine's 39 floats are still connected to the existing PTO system. As the existing PTO system can be applied to the 39 floats simultaneously with the new PTO used on 1 float, effect can be measured on the two systems simultaneously. The first tentative experiments with the new second generation PTO seem very promising. During the first measurements made in March 2009 the new system achieved an average yield of 3.1 times the average output from a float on the existing machine. In the coming period more experiments will be performed with the mini-hydraulic station to test the new PTO in various sea conditions. Since the mini-hydraulic station can simulate various forms of control, they also will be tested under real wave conditions in Nissum Bredning. The effect optimization should continue to be subject to a greater targeted effort, as improvements in this area can increase energy production and thus reduce the kWh cost of energy

    2010-08-24

    This paper presents current and projected savings for ENERGY STAR labeled products, and details the status of the model as implemented in the September 2009 spreadsheets. ENERGY STAR is a voluntary energy efficiency labeling program operated jointly by the Environmental Protection Agency (US EPA) and the U.S. Department of Energy (US DOE), designed to identify and promote energy-efficient products, buildings and practices. Since the program inception in 1992, ENERGY STAR has become a leading international brand for energy efficient products, and currently labels more than thirty products, spanning office equipment, heating, cooling and ventilation equipment, commercial and residential lighting, home electronics, and major appliances. ENERGY STAR's central role in the development of regional, national and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with stakeholders. This report presents savings estimates for ENERGY STAR labeled products. We present estimates of energy, dollar, and carbon savings achieved by the program in the year 2008, annual forecasts for 2009 and 2010, and cumulative savings estimates for the period 1993 through 2008 and cumulative forecasts for the period 2009 through 2015. Through 2008 the program saved 8.8 Quads of primary energy and avoided the equivalent of 158 metric tones carbon (MtC). The forecast for the period 2009-2015 is 18.1 Quads or primary energy saved and 316 MtC emissions avoided. The sensitivity analysis bounds the best estimate of carbon avoided between 104 MtC and 213 MtC (1993 to 2008) and between 206 MtC and 444 MtC (2009 to 2015). In this report we address the following questions for ENERGY STAR labeled products: (1) How are ENERGY STAR impacts quantified; (2) What are the ENERGY STAR achievements; and (3) What are the limitations to our method?

    Recent progress in quantum Monte Carlo with modern nucleon-nucleon interactions have enabled the successful description of properties of light nuclei and neutron-rich matter. Of particular interest is the nuclear symmetry energy, the energy cost of creating an isospin asymmetry, and its connection to the structure of neutron stars. Combining these advances with recent observations of neutron star masses and radii gives insight into the equation of state of neutron-rich matter near and above the saturation density. In particular, neutron star radius measurements constrain the derivative of the symmetry energy.

  1. Energy flux determines magnetic field strength of planets and stars.

    The magnetic fields of Earth and Jupiter, along with those of rapidly rotating, low-mass stars, are generated by convection-driven dynamos that may operate similarly (the slowly rotating Sun generates its field through a different dynamo mechanism). The field strengths of planets and stars vary over three orders of magnitude, but the critical factor causing that variation has hitherto been unclear. Here we report an extension of a scaling law derived from geodynamo models to rapidly rotating stars that have strong density stratification. The unifying principle in the scaling law is that the energy flux available for generating the magnetic field sets the field strength. Our scaling law fits the observed field strengths of Earth, Jupiter, young contracting stars and rapidly rotating low-mass stars, despite vast differences in the physical conditions of the objects. We predict that the field strengths of rapidly rotating brown dwarfs and massive extrasolar planets are high enough to make them observable.

    ENERGY STAR is a voluntary energy efficiency labeling program operated jointly by the Environmental Protection Agency (US EPA) and the U.S. Department of Energy (US DOE), designed to identify and promote energy-efficient products, buildings and practices. Since the program inception in 1992, ENERGY STAR has become a leading international brand for energy efficient products, and currently labels more than thirty products, spanning office equipment, heating, cooling and ventilation equipment, commercial and residential lighting, home electronics, and major appliances. ENERGY STAR's central role in the development of regional, national and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with stakeholders. This report presents savings estimates from the use ENERGY STAR labeled products. We present estimates of energy, dollar, and carbon savings achieved by the program in the year 2009, annual forecasts for 2010 and 2011, and cumulative savings estimates for the period 1993 through 2009 and cumulative forecasts for the period 2010 through 2015. Through 2009 the program saved 9.5 Quads of primary energy and avoided the equivalent of 170 million metric tons carbon (MMTC). The forecast for the period 2009-2015 is 11.5 Quads or primary energy saved and 202 MMTC emissions avoided. The sensitivity analysis bounds the best estimate of carbon avoided between 110 MMTC and 231 MMTC (1993 to 2009) and between 130 MMTC and 285 MMTC (2010 to 2015).

    The cooling of neutron stars by URCA processes in the kaon-condensed neutron star matter for various forms of nuclear symmetry energy is investigated. The kaon-nucleon interactions are described by a chiral Lagrangian. Nuclear matter energy is parametrized in terms of the isoscalar contribution and the nuclear symmetry energy in the isovector sector. High density behaviour of nuclear symmetry energy plays an essential role in determining the composition of the kaon-condensed neutron star matter which in turn affects the cooling properties. We find that the symmetry energy which decreases at higher densities makes the kaon-condensed neutron star matter fully protonized. This effect inhibits strongly direct URCA processes resulting in slower cooling of neutron stars as only kaon-induced URCA cycles are present. In contrast, for increasing symmetry energy direct URCA processes are allowed in the almost whole density range where the kaon condensation exists.

    Between 1990 and 2004, greenhouse gas (GHG) emissions from the residential sector have grown by 10 per cent, and are likely to continue growing unless a policy aimed at reducing emissions is introduced. The residential sector is a significant contributor to Canada's overall GHG emissions, and an important source for potential reductions. This report presented the results of a study that described and evaluated a new economic instrument aimed at reducing greenhouse gas (GHG) emissions and energy consumption in Canada from household appliances, such as air conditioners, furnaces and boilers. Results of a quantitative analysis to determine the effect of changing taxation of residential appliances to reflect energy consumption and greenhouse gas emissions were presented. In addition, the report presented the results of a qualitative evaluation of the policy, using the criteria established in the 2005 budget plan, a framework for evaluating environmental tax proposals. The report outlined the context for the tax proposal that was evaluated and provided a summary of trends in Canada's greenhouse gas emissions and energy consumption as well as a discussion of important trends in residential energy consumption. A review of policies already in place to address energy consumption from household appliances was also presented. 11 tabs., 6 figs

  12. Savings potential of ENERGY STAR (registered trademark) voluntary labeling programs

    1998-01-01

    In 1993 the U.S. Environmental Protection Agency (EPA) introduced ENERGY STAR (registered trademark), a voluntary labeling program designed to identify and promote energy-efficient products. Since then EPA, now in partnership with the U.S. Department of Energy (DOE), has introduced programs for more than twenty products, spanning office equipment, residential heating and cooling equipment, new homes, commercial and residential lighting, home electronics, and major appliances. We present potential energy, dollar and carbon savings forecasts for these programs for the period 1998 to 2010. Our target market penetration case represents our best estimate of future ENERGY STAR savings. It is based on realistic market penetration goals for each of the products. We also provide results under the assumption of 100% market penetration; that is, we assume that all purchasers buy ENERGY STAR-compliant products instead of standard efficiency products throughout the analysis period. Finally, we assess the sensitivity of our target penetration case forecasts to greater or lesser marketing success by EPA and DOE, lower-than-expected future energy prices, and higher or lower rates of carbon emission by electricity generators. The potential savings of ENERGY STAR are substantial. If all purchasers chose Energy Star-compliant products instead of standard efficiency products over the next 15 years, they would save more than$100 billion on their energy bills during those 15 years. (Bill savings are in 1995 dollars, discounted at a 4% real discount rate.)

    In the present paper we study the oscillation spectrum of neutron stars containing both ordinary matter and dark energy in different proportions. Within the model we consider, the equilibrium configurations are numerically constructed and the results show that the properties of the mixed neuron-dark-energy star can differ significantly when the amount of dark energy in the stars is varied. The oscillations of the mixed neuron-dark-energy stars are studied in the Cowling approximation. As a result we find that the frequencies of the fundamental mode and the higher overtones are strongly affected by the dark energy content. This can be used in the future to detect the presence of dark energy in the neutron stars and to constrain the dark-energy models.

    2009-09-24

    This report provides a top-level summary of national savings achieved by the Energy Star voluntary product labeling program. To best quantify and analyze savings for all products, we developed a bottom-up product-based model. Each Energy Star product type is characterized by product-specific inputs that result in a product savings estimate. Our results show that through 2007, U.S. EPA Energy Star labeled products saved 5.5 Quads of primary energy and avoided 100 MtC of emissions. Although Energy Star-labeled products encompass over forty product types, only five of those product types accounted for 65percent of all Energy Star carbon reductions achieved to date, including (listed in order of savings magnitude)monitors, printers, residential light fixtures, televisions, and furnaces. The forecast shows that U.S. EPA?s program is expected to save 12.2 Quads of primary energy and avoid 215 MtC of emissions over the period of 2008?2015.

    This report proposes an analysis of different scenarios of energy policy for France by 2050, notably by studying four options of evolution of electricity supply in France (extension of the present nuclear fleet, speeding up the passage to third generation and even fourth generation nuclear reactors, progressive reduction of nuclear energy, and phasing out nuclear). The report analyses the European and world energy context (main challenges, energy policies in other countries), the challenges of the future French energy mix (present situation, constraints and uncertainties, criteria to be met by 2050), the issue of the French energy mix by 2050 with respect to the different scenarios (in terms of energy demand, energy supply)

  19. Hot neutron stars at birth and energy release

    1994-01-01

    For the discussion of hot neutron stars at birth, it is necessary to calculate the equation of state for a so-called 'supernova matter' consisting of a neutron-rich nuclear matter and degenerated leptons. One of the aims of this paper is to obtain the realistic results for the equation of state. In 10-20s after the birth, new born hot neutron stars are cooled down by neutrino diffusion process, and gradually contract to usual cold neutron starts. It is another aim of this paper to determine how much energy is released during this cooling stage. The points to which attention was paid are explained. A three-nucleon interaction was introduced phenomenologically, as a two-nucleon interaction is insufficient to satisfy the empirical saturation property of symmetric nuclear matters. The separation of uncertain part from well-known part has the merit to clarify the dependence of the results on the present theoretical uncertainties. The validity of the simplified calculation as an approximation for the exact calculation is discussed. The results by both calculations were compared for the case of hot symmetric nuclear matters. The comparison of the density profiles for a hot neutron star and a cold neutron star is shown. The binding energy for hot and cold neutron stars was plotted. These results are examined. (K.I.)

    Significant progress has been made in recent years in constraining the density dependence of nuclear symmetry energy using terrestrial nuclear laboratory data. Around and below the nuclear matter saturation density, the experimental constraints start to merge in a relatively narrow region. At supra-saturation densities, there are, however, still large uncertainties. After summarizing the latest experimental constraints on the density dependence of nuclear symmetry energy, we highlight a few recent studies examining imprints of nuclear symmetry energy on the binding energy, energy release during hadron-quark phase transitions as well as the ω-mode frequency and damping time of gravitational wave emission of neutron stars.

    The functional form of the nuclear symmetry energy has only been determined in a very narrow range of densities. Uncertainties concern both the low as well as the high density behaviour of this function. In this work different shapes of the symmetry energy, consistent with the experimental data, were introduced and their consequences for the crustal properties of neutron stars are presented. The resulting models are in agreement with astrophysical observations.

    Gershberg, R.E.

    1985-01-01

    Accounting the observed power character of the energy spectrum of flares of the UV Cet-type stars, several statistical characterisitics of there stars are considered. It is shown that a mean amplitude of flares is mainly determined with an amplitude of the faintest flare that can be registered at the star under consideration and therefore - contrary to tradition - the mean flare amplitude cannot be used as a measure of a flare activity of the star. Mean frequencuy of flares registered at a flare star dependes statisticaally certainly ona an absolute magneitude of the star - contary to wide spread belief, true mean frequencies are higher at brighter stars. On the basis of the Cataloque of flare stars in Pleiades by Haro, Chavira and Gonzalez a luminosity function of therese stars is constructed. Using this function and the revealed dependence of flare mean frequencies on stellar absolute magnitudes, a distribution of flare stars in Pleiades along flare mean frequencies is constructed. This shows that the cluster contains flare stars with mean frequencies of photographically registered flares from 10 -4 to 10 -2 hour -1 or within even narrower interval of frequencies and the total number of such stars in the cluster exceeds 1100

    In 1988 the Governor`s Energy Management Center of Texas received approval from the US Department of Energy to establish a $98.6 million state-wide retrofit demonstration revolving loan program to fund energy-conserving retrofits in state, public school, and local government buildings. As part of this program, a first-of-its-kind, statewide Monitoring and Analysis Program (MAP) was established to verify energy and dollar savings of the retrofits, reduce energy costs by identifying operational and maintenance improvements, improve retrofit selection in future rounds of the LoanSTAR program, and initiate a data base of energy use in institutional and commercial buildings located in Texas. This report discusses the LoanSTAR MAP with an emphasis on the process of acquiring and analyzing data to measure savings from energy conservation retrofits when budgets are a constraint. This report includes a discussion of the program structure, basic measurement techniques, data archiving and handling, data reporting and analysis, and includes selected examples from LoanSTAR agencies. A summary of the program results for the first two years of monitoring is also included.

    Newton, W G; Gearheart, M; Wen, De-Hua; Li, Bao-An

    2013-01-01

    The modeling of many neutron star observables incorporates the microphysics of both the stellar crust and core, which is tied intimately to the properties of the nuclear matter equation of state (EoS). We explore the predictions of such models over the range of experimentally constrained nuclear matter parameters, focusing on the slope of the symmetry energy at nuclear saturation density L. We use a consistent model of the composition and EoS of neutron star crust and core matter to model the binding energy of pulsar B of the double pulsar system J0737-3039, the frequencies of torsional oscillations of the neutron star crust and the instability region for r-modes in the neutron star core damped by electron-electron viscosity at the crust-core interface. By confronting these models with observations, we illustrate the potential of astrophysical observables to offer constraints on poorly known nuclear matter parameters complementary to terrestrial experiments, and demonstrate that our models consistently predict L < 70 MeV.

  16. The Sun - From the star to domestic energy

    International Nuclear Information System (INIS)

    2009-06-01

    Considered as a star and a deity, for a long period of time the Sun was thought to be another planet, whereas the word 'star' was reserved for all the brilliant points of light in the night sky. The Sun's status as a star in the sense of 'an astral body producing and emitting energy' was firmly established only at the beginning of the 20. century. Today astrophysicists are revealing more and more secrets of the fusion burning region located in its core. It is thanks to the Sun that life has appeared and evolved on Earth; it controls the cycle of 'For the last 4.6 million years the Sun has being providing us with light and heat. Today it is man's ambition to control this energy source'. The seasons and provides us with heat and light. But what exactly is the nature and origin of this prodigious energy source, with which man attempts to provide warmth and produce electricity? What is happening in this gigantic ball of fire, impossible to observe without protective glasses? And finally, how long will it continue to shine? Questions such as these took many centuries to be solved and will continue to be the subject of research for a long time to come. (authors)

    All available low-resolution IUE spectra are assembled for Galactic, LMC, and SMC W-R stars and are merged with ground-based optical and NIR spectra in order to collate in a systematic fashion the shapes of these energy distributions over the wavelength range 0.1-1 micron. They can be consistently fitted by a power law of the form F(lambda) is approximately equal to lambda exp -alpha over the range 1500-9000 A to derive color excesses E(B-V) and spectral indices by removing the 2175-A interstellar absorption feature. The WN star color excesses derived are found to be in good agreement with those of Schmutz and Vacca (1991) and Koesterke et al. (1991). Significant heterogeneity in spectral index values was generally seen with any given subtype, but the groups consisting of the combined set of Galactic and LMC W-R stars, the separate WN and WC sequences, and the Galactic and LMC W-R stars all showed a striking and consistent Gaussian-like frequency distribution of values.

The goal of the STAR (STrengthening Altitude Research) initiative was to produce a uniform set of key elements for research and reporting in clinical high-altitude (HA) medicine. The STAR initiative was inspired by research on treatment of cardiac arrest, in which the establishment of the Utstein Style, a uniform data reporting protocol, substantially contributed to improving data reporting and subsequently the quality of scientific evidence. The STAR core group used the Delphi method, in which a group of experts reaches a consensus over multiple rounds using a formal method. We selected experts in the field of clinical HA medicine based on their scientific credentials and identified an initial set of parameters for evaluation by the experts. Of 51 experts in HA research who were identified initially, 21 experts completed both rounds. The experts identified 42 key parameters in 5 categories (setting, individual factors, acute mountain sickness and HA cerebral edema, HA pulmonary edema, and treatment) that were considered essential for research and reporting in clinical HA research. An additional 47 supplemental parameters were identified that should be reported depending on the nature of the research. The STAR initiative, using the Delphi method, identified a set of key parameters essential for research and reporting in clinical HA medicine.

    The phenomenological approach to inhomogeneous nuclear matter is useful to describe fundamental properties of atomic nuclei and neutron star crusts in terms of the equation of state of uniform nuclear matter. We review a series of researches that we have developed by following this approach. We start with more than 200 equations of state that are consistent with empirical masses and charge radii of stable nuclei and then apply them to describe matter radii and masses of unstable nuclei, proton elastic scattering and total reaction cross sections off unstable nuclei, and nuclei in neutron star crusts including nuclear pasta. We finally discuss the possibility of constraining the density dependence of the symmetry energy from experiments on unstable nuclei and even observations of quasi-periodic oscillations in giant flares of soft gamma-ray repeaters.

    The improvement of existing homes in the United States can have a much greater impact on overall residential energy use than the construction of highly efficient new homes. There are over 130 million existing housing units in the U.S., while annually new construction represents less than two percent of the total supply (U.S. Census Bureau, 2013). Therefore, the existing housing stock presents a clear opportunity and responsibility for Building America (BA) to guide the remodeling and retrofit market toward higher performance existing homes. There are active programs designed to improve the energy performance of existing homes. Home Performance with ENERGY STAR (HPwES) is a market-rate program among them. BARA's research in this project verified that the New Jersey HPwES program is achieving savings in existing homes that meet or exceed BA's goal of 30%. Among the 17 HPwES projects with utility data included in this report, 15 have actual energy savings ranging from 24% to 46%. Further, two of the homes achieved that level of energy savings without the costly replacement of heating and cooling equipment, which indicates that less costly envelope packages could be offered to consumers unable to invest in more costly mechanical packages, potentially creating broader market impact.

    The Clementine mission provided the first ever complete, systematic surface mapping of the moon from the ultra-violet to the near-infrared regions. More than 1.7 million images of the moon, earth and space were returned from this mission. Two star stracker stellar compasses (star tracker camera + stellar compass software) were included on the spacecraft, serving a primary function of providing angle updates to the guidance and navigation system. These cameras served a secondary function by providing a wide field of view imaging capability for lunar horizon glow and other dark-side imaging data. This 290 g camera using a 576 x 384 focal plane array and a 17 mm entrance pupil, detected and centroided stars as dim and dimmer than 4.5 m{sub v}, providing rms pointing accuracy of better than 100 {mu}rad pitch and yaw and 450 {mu}rad roll. A description of this light-weight, low power star tracker camera along with a summary of lessons learned is presented. Design goals and preliminary on-orbit performance estimates are addressed in terms of meeting the mission`s primary objective for flight qualifying the sensors for future Department of Defense flights. Documentation generated during the design, analysis, build, test and characterization of the star tracker cameras are presented. Collectively, this documentation represents a small library of information for this camera, and may be used as a framework for producing copy units by commercial enterprises, and therefore satisfies a Department of Defense and Department of Energy goal to transfer technology to industry. However, the considerable knowledge gained from the experience of the individuals involved in the system trades, design, analysis, production, testing and characterization of the star tracker stellar compass is not contained in this documentation.

    This report on the new energy technologies has been written by a working group on request of the French ministry of economy, finances and industry, of the ministry of ecology and sustainable development, of the ministry of research and new technologies and of the ministry of industry. The mission of the working group is to identify goals and priority ways for the French and European research about the new technologies of energy and to propose some recommendations about the evolution of research incentive and sustain systems in order to reach these goals. The working group has taken into consideration the overall stakes linked with energy and not only the climatic change. About this last point, only the carbon dioxide emissions have been considered because they represent 90% of the greenhouse gases emissions linked with the energy sector. A diagnosis is made first about the present day context inside which the new technologies will have to fit with. Using this diagnosis, the research topics and projects to be considered as priorities for the short-, medium- and long-term have been identified: energy efficiency in transports, in dwellings/tertiary buildings and in the industry, development for the first half of the 21. century of an energy mix combining nuclear, fossil-fuels and renewable energy sources.

    We study the production of high energy neutrinos in jets from the tidal disruption of stars by supermassive black holes. The diffuse neutrino flux expected from these tidal disruption events (TDEs) is calculated both analytically and numerically, taking account the dependence of the rate of TDEs on the redshift and black hole mass. We find that ∝ 10% of the observed diffuse flux at IceCube at an energy of about 1 PeV can come from TDEs if the characteristics of known jetted tidal disruption events are assumed to apply to the whole population of these sources. If, however, plausible scalings of the jet Lorentz factor or variability timescale with the black hole mass are taken into account, the contribution of the lowest mass black holes to the neutrino flux is enhanced. In this case, TDEs can account for most of the neutrino flux detected at IceCube, describing both the neutrino flux normalization and spectral shape with moderate baryonic loadings. While the uncertainties on our assumptions are large, a possible signature of TDEs as the origin of the IceCube signal is the transition of the flux flavor composition from a pion beam to a muon damped source at the highest energies, which will also result in a suppression of Glashow resonance events.

  10. High-energy emission from star-forming galaxies

    2011-01-01

    Adopting the convection-diffusion model for energetic electron and proton propagation, and accounting for al lthe relevant hadronic and leptonic processes, the steady-state energy distributions of these particles in the starburst galaxies M 82 and NGC 253 can be determined with a detailed numerical treatment. The electron distribution is directly normalized by the measured synchrotron radioemission from the central starburst region; a commonly expected theoretical relationis then used to normalize the proton spectrum in thisr egion, and a radial profile is assumed for the magnetic field. The resulting radiative yields of electrons and protons are calculated: thepredicted > 100MeV and > 100GeV fluxes are in agreement with the corresponding quantities measured with the orbiting Fermite lescope and the ground-based VERITAS and HESS Cherenkov telescopes. The cosmic-rayenergy densities in central regions of starburst galaxies, as inferred from the radioand γ-ray measurements of (respectively) non-thermal synchrotron and π 0 -decay emission, are U p = O(100)eVcm -3 , i.e. at least an order of magnitude larger than near the Galactic center and in other non-very-actively star-forming galaxies. These very different energy density levelsr eflect a similar disparity in the respective supernova rates in the two environments. A L γ proper to SFR 1.4 relationship is then predicted, in agreement with preliminary observational evidence.

  11. Energy upgrades as financial or strategic investment? Energy Star property owners and managers improving building energy performance

    International Nuclear Information System (INIS)

    Gliedt, Travis; Hoicka, Christina E.

    2015-01-01

    Highlights: • Energy Star property owners/managers view energy as strategic or financial investments. • Energy performance improvements and motivations differ by property type. • Energy projects are most often funded by internal cash reserves. • Motivations and funding sources differ by type of energy project. • Environmental sustainability is an important criterion in many energy projects. - Abstract: Due to its significant carbon footprint and cost-effectiveness for upgrades, the commercial property sector is important for climate change mitigation. Although barriers to energy system changes, such as funding, financing and information, are well recognized, Energy Star property owners and managers are successfully overcoming these barriers and instigating energy efficiency upgrades, renewable energy installations, and behavior and management programs. To examine the decision-making process that leads to energy performance improvements, a national survey of property owners and management organizations of buildings that earned an Energy Star score of 75 or higher was conducted. The extent to which energy upgrades were considered strategic investments motivated by environmental sustainability or corporate social responsibility, or financial investments motivated by payback period or return-on-investment criteria, was contingent upon the property type and type of energy project. Environmental sustainability was found to be an important motivation for energy projects in office spaces in general, but in the case of smaller office spaces was often combined with motivations for corporate social responsibility. Energy projects on education properties were motivated by financial investment. Building envelope and mechanical efficiency upgrades were considered financial investments, while renewable energy, green roofs, and water conservation technologies were considered environmental sustainability initiatives

    2011-01-01

    In the United States, nearly 17% of greenhouse gas emissions come from residential energy use. Increases in energy efficiency for the residential sector can generate significant energy savings and emissions reductions. Consumer labels, such as the US Environmental Protection Agency's ENERGY STAR, promote conservation by providing consumers with information on energy usage for household appliances. This study examines how the ENERGY STAR label affects consumer preferences for refrigerators. The results of an online survey of a national sample of adults suggest that consumers are, on average, willing to pay an extra $249.82-$349.30 for a refrigerator that has been awarded the ENERGY STAR label. Furthermore, the results provide evidence that respondent willingness-to-pay was motivated by both private (energy cost savings) and public (environmental) benefits. - Research highlights: → Results of a contingent choice experiment from an online survey of a national sample suggest that consumers are, on average, willing to pay an extra $249.82-$349.30 for a refrigerator awarded the ENERGY STAR label. → Preferences for ENERGY STAR refrigerators are motivated by both private (energy cost savings) and public (environmental) benefits. → Preferences for ENERGY STAR refrigerators decrease with age but are stronger among males than among females.

    Home Performance with ENERGY STAR (HPwES) is a jointly managed program of the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). This program focuses on improving energy efficiency in existing homes via a whole-house approach to assessing and improving a home's energy performance, and helping to protect the environment. As one of HPwES's local sponsors, Austin Energy's HPwES program offers a complete home energy analysis and a list of recommendations for efficiency improvements, along with cost estimates. To determine the benefits of this program, the National Renewable Energy Laboratory (NREL) collaborated with the Pacific Northwest National Laboratory (PNNL) to conduct a statistical analysis using energy consumption data of HPwES homes provided by Austin Energy. This report provides preliminary estimates of average savings per home from the HPwES Loan Program for the period 1998 through 2006. The results from this preliminary analysis suggest that the HPwES program sponsored by Austin Energy had a very significant impact on reducing average cooling electricity for participating households. Overall, average savings were in the range of 25%-35%, and appear to be robust under various criteria for the number of households included in the analysis.

    The structure of two EPA programs directed towards wasted energy in buildings, reducing emissions, increasing energy efficiency and maximizing profits are described. The programs are based on a partnership approach between EPA and participants, and involve elements of plans and performance benchmarks, an integrated approach and communications and demonstration of successful initiatives. EPA provides planning and technical support in the form of a website, software tools, manuals, electronic sources and a purchasing tool kit. The Energy STAR Building Partnership has over 3,000 participants, and can boast of a cumulative saving of over $ 1.4 billion in energy bills and carbon dioxide emission reduction of 44.1 billion pounds, resulting from efficiency upgrades. The Natural Gas Partnership between the EPA and the oil and natural gas industry to cost effectively reduce methane emissions from the production, transmission, and distribution of natural gas also has had a number of successful initiatives such as replacement or retrofit of high bleed pneumatic devices, installation of flash tank separators on glycol dehydrators and other partner-reported projects such as replacement of wet seals with dry seals on compressors and connecting glycol pump to vapour recovery unit. As a results of these and other initiatives, annual methane emission was reduced by 22.2 bcf in 1998 as opposed to 3.4 bcf prior to the beginning of the program in 1993. Approximately 67 per cent of all reductions can be attributed to partner innovation. Overall assessment is that the program is innovative, achieves both economic and environmental goals, facilitates government and industry cooperation and is living proof that non-regulatory, cooperative programs work

    Bazan, G.

    1989-01-01

    We report on the non-negligible energy generation from the 13 C neutron source and neutron capture reactions in low mass, low metallicity AGB stars. About 10 4 L circle-dot are generated within the thermal pulse convective shell by the combination of the 13 C(α, n) 16 O rate and the sum of the Y(Z,A)(n,γ)Y(Z,A + 1) reactions and beta decays. The inclusion of this energy source in an AGB thermal pulse evolution is shown to alter the evolution of the convective shell boundaries, and, hence, how the 13 C is ingested into the convective shell. Also, the duration of the pulse itself is reduced by the additional energy input. The nucleosynthetic consequences are discussed for these evolutionary changes. 17 refs., 5 figs

    The effect of the strong gravitational field of the strange core of a strange star on its surface electrostatic potential energy distribution is discussed. We present the general-relativistic hydrodynamics equations of fluids in the presence of the electric fields and investigate the surface electrostatic potential distribution of the strange core of a strange star in hydrostatic equilibrium to correct Alcock and coworker's result [Astrophys. J. 310 (1986) 261]. Also, we discuss the temperature distribution of the bare strange star surface and give the related formulae, which may be useful if we are concerned further about the physical processes near the quark atter surfaces of strange stars.

    Hanawa, Tomoyuki

    1991-01-01

    It is shown by Monte Carlo simulation that high-energy X-rays are produced through Compton scattering in a boundary layer of an accreting neutron star. The following is the mechanism for the high-energy X-ray production. An accreting neutron star has a boundary layer rotating rapidly on the surface. X-rays radiated from the star's surface are scattered in part in the boundary layer. Since the boundary layer rotates at a semirelativistic speed, the scattered X-ray energy is changed by the Compton effect. Some X-rays are scattered repeatedly between the neutron star and the boundary layer and become high-energy X-rays. This mechanism is a photon analog of the second-order Fermi acceleration of cosmic rays. When the boundary layer is semitransparent, high-energy X-rays are produced efficiently. 17 refs

  20. Energy in Croatia 2003. Annual Energy Report

    International Nuclear Information System (INIS)

    2004-11-01

    Reports have kept domestic and international audience continuously informed about the latest relations and developments in the Croatian energy system. Annual report presents all characteristic indicators of the Croatian energy system in 2003, outlines their development over a longer past period, and suggests a future course of development of basic energy system indicators. Total primary energy supply in the Republic of Croatia in 2003 was 5.2 percent higher compared to the previous year. The gross domestic product increased by 4.3 percent over the same period. This means that energy intensity, primary energy supply per unit of gross domestic product, increased by 0.9 percent. Compared to the european Union average Croatian energy intensity was approximately 32 percent higher. Total primary energy production, on the other hand, decreased by 1.1 percent compared to 2002. This means that primary energy self-supply, which fell to 46.4 percent, reached its lowest level to-date in the observed period. The remaining energy needs were met by imports, which increased by 1.7 percent. In the structure of total primary energy supply, decrease has been observed only in energy conversion losses, while all other categories increased. Final energy demand increased by 6.7 percent in 2003, with the levels recorded in different sectors ranging from 2.5 percent in industry to 7.5 and 8 percent in transport and other sectors, respectively. In terms of final energy demand, an increase has been recorded in all energy forms except natural gas, whose consumption showed stagnation. This is due to lower consumption in the energy transformation sector and a significant 9.2 percent increase in its final energy demand. A continuous increase in electricity consumption - which reached 4.8 percent in the observed period - is worth nothing. Energy forms which recorded highest consumption increase levels in 2003 are coal (16 percent) and diesel fuel (15 percent). In contrast to the fast increase in

    The project encompassed following activities: Elaboration of a description of the Russian dairy sector including a mapping of the entire sector in respect of production capacity, actual production, products, production technologies and energy consumption; Energy audits at twelve selected dairies with different typical productions; Elaboration of an `Energy Audit Guidance` which describes how to perform energy audits in dairies and where to expect energy saving possibilities. The energy savings possibilities are often due to the same kind of problems, e.g. low production, inefficient equipment or manually control of the process equipment. The main problems that Russian dairies faces can be divided into the following categories: Old and inefficient technological equipment which is operated at low capacity with very low energy efficiency; Lack of knowledge about new energy efficient technologies; Financial problems which causes low interest and few possibilities for using funds for investment in energy efficient equipment; Energy savings do not lead to personal gains for the persons in the dairy management or other employees which causes low interst in energy savings. At some dairies it seemed to be a problem for the management to adapt to the new and very different conditions for enterprises in Russian today, where sales, production, production capacity and raw milk available are interconnected. With respect to energy matters it was often a wish to replace existing oversized equipment with new equipment of the same size no matter that it is unlikely that the production will increase considerable in the future. The project has discovered that there is a need for demonstrating energy saving measures by implementation because it was in many ways hard for the dairy management`s to believe that, the energy consumption could be reduced dramatically without affecting could production or the processes.

    International Nuclear Information System (INIS)

    2005-11-01

    Report represents a continuous information source for both national and international public on relations and trends in the Croatian energy system. This edition brings certain changes in the energy topics' outline and broader scope of information compared to the previous editions. However, the representative features of the Croatian energy sector, related to supply and demand of energy at all levels, kept the familiar outlook of presentation.Besides the detailed analysis of energy trends, this edition provides numerous information on capacity, reserves and prices of energy as well as individual energy sources' balances - crude oil and oil derivates, natural gas, electricity, heat, coal and renewable energy sources. In addition, Croatian basic and economic and financial indicators, emission of air pollutants plus basic energy efficiency indicators were presented in order to give better understanding of the Croatian energy sector environment. Finally, there is a special novelty of representing energy balances of the Republic of Croatia made in the compliance with EUROSTAT and IEA methodology for years 2003 and 2004. Total primary energy supply in the Republic of Croatia in 2004 was 4.1 percent higher compared to the previous year. The gross domestic product increased by 3.8 percent over the same period. This means that energy intensity, primary energy supply per unit of gross domestic product, increased by 0.3 percent. Compared to the European Union average Croatian energy intensity was approximately 24 percent higher. Total primary energy production, on the other hand, increased by 11.2 percent due to extremely favourable hydrological conditions. The raise i n hydropower by 48.5 percent improved Croatian primary energy self-supply to 49.6 percent. In the structure of total primary energy supply for 2004, the losses of transmission and distribution of energy were reduced only while the rest of the categories of energy consumption increased. The 3.3 percent increase

    This report is a summary of work done during FY 1988 (October 1, 1987--September 30, 1988) by the Energy Program of the Lawrence Livermore National Laboratory (LLNL). The program addresses problems relating to supply and utilization of energy in the US. Traditionally the focus of activities has been on long-range technical challenges that are unlikely to be pursued by the private sector. Individual projects making up the Energy Program are divided into three sections in this review: Nuclear Energy, Fossil Energy, and Nonfossil Energy. (Nonfossil Energy research includes work on geothermal resources and combustion chemistry.)

    2013-09-01

    Through the Chicagoland Single Family Housing Characterization and Retrofit Prioritization report, the Partnership for Advanced Residential Retrofit characterized 15 housing types in the Chicagoland region based on assessor data, utility billing history, and available data from prior energy efficiency programs. Within these 15 groups, a subset showed the greatest opportunity for energy savings based on BEopt Version 1.1 modeling of potential energy efficiency package options and the percent of the housing stock represented by each group. In this project, collected field data from a whole-home program in Illinois are utilized to compare marketplace-installed measures to the energy saving optimal packages previously developed for the 15 housing types. Housing type, conditions, energy efficiency measures installed, and retrofit cost information were collected from 19 homes that participated in the Illinois Home Performance with ENERGY STAR program in 2012, representing eight of the characterized housing groups. Two were selected for further case study analysis to provide an illustration of the differences between optimal and actually installed measures. Taken together, these homes are representative of 34.8% of the Chicagoland residential building stock. In one instance, actual installed measures closely matched optimal recommended measures.

  8. Omega report: energy policy

    International Nuclear Information System (INIS)

    1984-01-01

    The Adam Smith Institute's Omega Project was conceived to fill a significant gap in the field of public policy research. Administrations entering office in democratic societies are often aware of the problems which they face, but lack a well-developed range of policy options. The Omega Project was designed to create and develop new policy initiatives, to research and analyze these new ideas, and to bring them forward for public discussion in ways which overcame the conventional shortcomings. The organization of the Project is described. The results are presented in sections entitled: energy supplies and policy; the gas industry; North Sea oil; the coal industry; the electricity industry; nuclear energy; renewable and alternative fuel sources; energy conservation.

    International Nuclear Information System (INIS)

    2006-12-01

    Report presents the latest information on relations and trends in the Croatian energy sector. The reports gives a familiar overview of comprehensive data about and representative features of the Croatian energy sector, related to the supply and demand of energy at all levels. It produces a detailed analysis of energy trends and provides extensive data on capacity, reserves and prices as well as balances of individual energy sources - crude oil, petroleum products, natural gas, electricity, heat, coal and renewable source of energy. Basic economic and financial indicators, emissions of air pollutants and basic energy efficiency indicators for Croatia are also presented. In 2005, total primary energy supply in Croatia decreased slightly by 0.1 per cent with respect to the previous year. At the same time, GDP rose by 4.3 per cent, resulting in a drop in energy intensity of the total primary energy supply of 4.2 per cent. The energy intensity in Croatia was 20.1 per cent higher than the average energy intensity in the European Union, but a positive decreasing trend was noted during the past period. In 2005 the total primary energy production in Croatia fell by 3.5 per cent with respect to the previous year. The highest decrease was recorded in harnessing hydro power, and the production of crude oil and fuel wood also declined. Only the production of natural gas showed a growth of 3.5 per cent. Due to the decrease in the primary energy production, energy self-supply was also reduced to 47.9 per cent. A less value was achieved only in the year 2003. A continuing trend towards a gradual decline in energy self-supply was present throughout the past several years. Final energy demand increased by 3 per cent while demands in other sectors decreased. Energy transformation losses were reduced by 7 per cent, non-energy use declined by 5.6 per cent and energy transmission and distribution losses by 5.5 per cent, and there was a slight drop of 0.2 per cent in demand in energy

    The national economy is particularly dependent on efficient electrical generation and transportation. Electrical demand continues to grow and will increasingly rely on coal and nuclear fuels. The nuclear power industry still has not found a solution to the problem of disposing of the waste produced by nuclear reactors. Although coal is in ample supply and the infrastructure is in place for its utilization, environmental problems and improved conversion processes remain technical challenges. In the case of transportation, the nation depends almost exclusively on liquid fuels with attendant reliance on imported oil. Economic alternates---synfuels from coal, natural gas, and oil shale, or fuel cells and batteries---have yet to be developed or perfected so as to impact the marketplace. Inefficiencies in energy conversion in almost all phases of resource utilization remain. These collective problems are the focus of the Energy Program.

  15. Energy in Croatia 2002. Annual Energy Report

    International Nuclear Information System (INIS)

    2003-01-01

    The review, in its own recognisable way, consists of the most recent and settled data on the Croatian energy system for the period up to and including the year 2002. Some data appertain to a longer time period with the aim of an easier insight into long-term prospects. In 2002 total primary energy supply exceeded the year before by 1.3 percent. Owing to the simultaneous growth of the gross domestic product by 5.2 percent, energy intensity decreased thus marking the third year of a positive trend. However, it has to be mentioned that energy intensity, which expresses the total energy consumed per unit of gross domestic product, exceeded the level of the developed European countries by 33 percent, although it was still more favourable than in the majority of transition countries. Supply from own sources fell to the less than 50 percent, and energy import, with oil in the leading position, recorded an average annual increase of 4.7 percent. In 2002 transformation losses as well as transportation and distribution losses decreased thus bringing about the already mentioned total energy consumption growth of 1.3 percent and final demand increase by 2.3 percent - this means that the energy system was more efficient. The year 2002 recorded a consumption increase in traffic by 6.2 percent, in other sectors by 3 percent, while industry realised a decrease by 3.9 percent. It should be emphasised that diesel fuel recorded a major increase and in the whole structure almost reached the level of the motor gasoline. From 1995 till the end of the period observed the gas distribution network was doubled in length. The report includes other interesting information about our energy system, i.e. capacities, energy, source prices, as well as environmental impact from the energy sector

    Two fluorescence processes operating in atmospheres of cool stars, symbiotic stars, and the Sun are presented. Two emission lines, at 1347.03 and 1360.17 A, are identified as fluorescence lines of Cr II and Fe II. The lines are due to transitions from highly excited levels, which are populated radiatively by the hydrogen Lyman alpha line due to accidental wavelength coincidences. Three energy levels, one in Cr II and two in Fe II, are reported.

    Considering the non-Newtonian gravity proposed in grand unification theories, we show that the stability and observed global properties of neutron stars cannot rule out the supersoft nuclear symmetry energies at suprasaturation densities. The degree of possible violation of the inverse-square law of gravity in neutron stars is estimated using an equation of state of neutron-rich nuclear matter consistent with the available terrestrial laboratory data.

  18. EPA ENERGY STAR: Tackling Growth in Home Electronics and Small Appliances

    Energy Technology Data Exchange (ETDEWEB)

    Sanchez, Marla Christine; Brown, Richard; Homan, Gregory

    2008-11-17

    Over a decade ago, the electricity consumption associated with home electronics and other small appliances emerged onto the global energy policy landscape as one of the fastest growing residential end uses with the opportunity to deliver significant energy savings. As our knowledge of this end use matures, it is essential to step back and evaluate the degree to which energy efficiency programs have successfully realized energy savings and where savings opportunities have been missed.For the past fifteen years, we have quantified energy, utility bill, and carbon savings for US EPA?s ENERGY STAR voluntary product labeling program. In this paper, we present a unique look into the US residential program savings claimed to date for EPA?s ENERGY STAR office equipment, consumer electronics, and other small household appliances as well as EPA?s projected program savings over the next five years. We present a top-level discussion identifying program areas where EPA?s ENERGY STAR efforts have succeeded and program areas where ENERGY STAR efforts did not successfully address underlying market factors, technology issues and/or consumer behavior. We end by presenting the magnitude of ?overlooked? savings.

    We present the calibration of the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray satellite. We used the Crab as the primary effective area calibrator and constructed a piece-wise linear spline function to modify the vignetting response. The achieved residuals for all off-axis angles and energies, compared to the assumed spectrum, are typically better than ±2% up to 40 keV and 5%–10% above due to limited counting statistics. An empirical adjustment to the theoretical two-dimensional point-spread function (PSF) was found using several strong point sources, and no increase of the PSF half-power diameter has been observed since the beginning of the mission. We report on the detector gain calibration, good to 60 eV for all grades, and discuss the timing capabilities of the observatory, which has an absolute timing of ±3 ms. Finally, we present cross-calibration results from two campaigns between all the major concurrent X-ray observatories (Chandra, Swift, Suzaku, and XMM-Newton), conducted in 2012 and 2013 on the sources 3C 273 and PKS 2155-304, and show that the differences in measured flux is within ∼10% for all instruments with respect to NuSTAR.

    In this work we study the effect of the symmetry energy on several properties of neutron stars. First, we discuss its effect on the density, proton fraction and pressure of the neutron star crust-core transition. We show that whereas the first two quantities present a clear correlation with the slope parameter L of the symmetry energy, no satisfactory correlation is seen between the transition pressure and L. However, a linear combination of the slope and curvature parameters at ρ = 0.1 fm{sup -3} is well correlated with the transition pressure. In the second part we analyze the effect of the symmetry energy on the pasta phase. It is shown that the size of the pasta clusters, number of nucleons and the cluster proton fraction depend on the density dependence of the symmetry energy: a small L gives rise to larger clusters. The influence of the equation of state at subsaturation densities on the extension of the inner crust of the neutron star is also discussed. Finally, the effect of the density dependence of the symmetry energy on the strangeness content of neutron stars is studied in the last part of the work. It is found that charged (neutral) hyperons appear at smaller (larger) densities for smaller values of the slope parameter L. A linear correlation between the radius and the strangeness content of a star with a fixed mass is also found. (orig.)

    2000-01-01

    ENERGY STAR7 is a voluntary labeling program designed to identify and promote energy-efficient products. Operated jointly by the Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE), ENERGY STAR labels exist for more than twenty products, spanning office equipment, residential heating and cooling equipment, new homes, commercial and residential lighting, home electronics, and major appliances. We present estimates of the energy, dollar and carbon savings already achieved by the program and provide savings forecasts for several market penetration scenarios for the period 2001 to 2010. The target market penetration forecast represents our best estimate of future ENERGY STAR savings. It is based on realistic market penetration goals for each of the products. We also provide a forecast under the assumption of 100 percent market penetration; that is, we assume that all purchasers buy ENERGY STAR-compliant products instead of standard efficiency products throughout the analysis period. Finally, we assess the sensitivity of our target penetration case forecasts to greater or lesser marketing success by EPA and DOE, lower-than-expected future energy prices, and higher or lower rates of carbon emissions by electricity generators

    Renwick, Lord; Stoddart, Lord; Lauderdale, Earl of

    1988-01-01

    The European Communities Committee Report on Alternative Energy Resources was debated. Six alternative energy sources were first described - wind power, biomass, geothermal energy, solar energy, wave and tidal power. Combined heat and power was also mentioned. General questions concerning alternative energy sources were then considered. In particular, their potential contribution to the energy demand was assessed. The evidence presented to the committee suggested that they would only make a small contribution in the near future and could not be considered as a substitute for coal and nuclear power. However, by the year 2030 it would be possible for 18% of the national electricity demand to be met by alternative energy sources. The economic and environmental issues were assessed briefly and the report's conclusions were summarized. An independent review of wave power was called for in view of conflicting evidence presented to the committee. The debate which followed lasted three hours and is reported verbatim. Other issues raised included energy conservation, public attitudes to energy, the environment, government and private funding of research and development of nuclear power, including fusion. (U.K.)

    Highlights: • Normalization energy utilization indicators regression model is established. • Total and subentry normalization energy utilization indicators have been obtained and reported. • Found the key points in influencing hotels’ total and subentry energy consumption. • Discussed the best selection of building envelops to reduce the hotels’ energy consumption. - Abstract: This paper reported a study of energy consumption of 27 starred hotels in Hainan Province. Total and subentry energy consumption indicators were defined to indicate the building energy efficiency after collecting the building basic information and energy consumption of these hotels. Eighteen potential independent significant factors were selected to analyze energy utilization indicators (EUIs) and the climate adjusted energy utilization indicators (EUI clt ) were calculated by using the degree-day method. Then, multiple regression analysis between EUI clt and continuous scale factors was applied to establish the normalization EUI data model and results indicated that the electricity percentage, number of guestrooms and equivalent guestrooms are the key points influencing total energy efficiency of hotels. Lastly, on the basis of multi-factor analysis of variance (ANOVA) between the EUI norm and categorical factors of the sampled hotel buildings, double glazing window is the significant factor that influences the total unit energy consumption greatly

    In the United States, industry spends over $100 billion annually to power its manufacturing plants. Companies also spend on maintenance, capital outlay, and energy services. Improving energy efficiency is vital to reduce these costs and increase earnings. Many cost-effective opportunities to reduce energy consumption are available, and this Energy Guide discusses energy-efficiency practices and energy-efficient technologies that can be applied over a broad spectrum of companies. Strategies in the guide address hot water and steam, compressed air, pumps, motors, fans, lighting, refrigeration, and heating, ventilation, and air conditioning. This guide includes descriptions of expected energy and cost savings, based on real-world applications, typical payback periods, and references to more detailed information. The information in this Energy Guide is intended to help energy and plant managers achieve cost-effective energy reductions while maintaining product quality. Further research on the economics of all measures--as well as on their applicability to different production practices?is needed to assess their cost effectiveness at individual plants.

    The lack of a system for benchmarking industrial plant energy efficiency represents a major obstacle to improving efficiency. While estimates are sometimes available for specific technologies, the efficiency of one plant versus another could only be captured by benchmarking the energy efficiency of the whole plant and not by looking at its components. This paper presents an approach used by ENERGY STAR to implement manufacturing plant energy benchmarking for the cement industry. Using plant-level data and statistical analysis, we control for factors that influence energy use that are not efficiency, per se. What remains is an estimate of the distribution of energy use that is not accounted for by these factors, i.e., intra-plant energy efficiency. By comparing two separate analyses conducted at different points in time, we can see how this distribution has changed. While aggregate data can be used to estimate an average rate of improvement in terms of total industry energy use and production, such an estimate would be misleading as it may give the impression that all plants have made the same improvements. The picture that emerges from our plant-level statistical analysis is more subtle; the most energy-intensive plants have closed or been completely replaced and poor performing plants have made efficiency gains, reducing the gap between themselves and the top performers, whom have changed only slightly. Our estimate is a 13 % change in total source energy, equivalent to an annual reduction of 5.4 billion/kg of energy-related carbon dioxide emissions.

    The Working Group on Energy (WG) was organized under International Union of Pure and Applied Physics (IUPAP). The WG has been considering problems on future energy supply and role of physics to solve the subjects. As one of activities of the WG, a Workshop on Energy was held on May 13, 2004 at Center for Promotion of Computational Science and Engineering, Japan Atomic Energy Research Institute (JAERI) in Tokyo hosted by IUPAP and co-hosted by JAERI and High Energy Accelerator Research Organization. The objectives of this workshop are to suggest active contributions of pure and applied physics field to the solution of the energy problem and to advance research and development (R and D) of future energy through the discussions about present status, problem and prospect of different energy development in the world and in Japan. This report records the summary of the Workshop and, abstracts and materials of 12 presentations. After the invited presentations about overview of energy problems in the world, in China and in Japan, R and D activities on the following four fields were presented; 'Research and Development of New Energy', 'Research and Development of Fusion', 'Prospect of Accelerator Driven System (ADS)', and 'Hydrogen Production, Storage and Transportation'. At the end of the workshop, possible role of physics for the current and future energy problem was discussed. It was recognized that the energy problem was not as simple as to be solved by one country, and hence the international collaboration became essential. The importance of the coordination with other fields, such as chemistry and material, was also emphasized. (author)

    2006-07-01

    This final report published by the Swiss Federal Office of Energy (SFOE) presents the results of a study made on so-called intelligent switches that switch an induction motor automatically into star configuration when at low load and, when higher loading returns, back again into the delta configuration. The results of theoretical calculations and measurements made in practice are discussed. The results are presented for various application areas including hydraulics, dynamic converters and standard applications. Also, the use of switches in applications such as wood-cutters, transport systems and stone-crushers are looked at. The results are discussed and the possible risks involved in the use of star-delta switches are looked at. Conclusions are drawn on their use from the economical point of view.

    2010-04-15

    The European Energy Law Report VII presents in four parts an overview of the most important legal developments in the field of EU and national energy and climate change law as discussed at the 2009 European Energy Law Seminar. The first part examines recent developments in EU climate change regulation. It includes an overview of the revision of the EU Directive governing CO2 emissions trading and a more detailed analysis of the new allocation regime, including the auctioning of emission rights. This is followed by an analysis of the competitiveness of the new EU emissions trading Directive and recent developments in the US regarding emissions trading. The second part focuses on the energy liberalisation process and the Third Energy Package. Following an overview of recent developments in EU competition law and the impact of the Sector Inquiry on the energy sector, this part concentrates particularly on the new Internal Energy Market Directives and most particularly on the legality of the unbundling provisions. Subsequently, the focus is on the role of the TSOs. After an analysis of the need for an increased cooperation of the German TSOs, another chapter discusses the need for more consolidation in the European gas transmission market and the role of regulation therein. Is there a new role for nuclear energy? In order to secure long term energy supply, the focus turns again to nuclear energy. The third part of this report discusses two elements of nuclear liability. First, it analyses the issue of the possible privatisation of the nuclear sector and its impact on long term liability. Although the focus is on the UK nuclear sector, a comparison is made with some other regulatory regimes. Next, the role of nuclear energy is discussed as an instrument to reduce CO2 emissions and, more particularly as a means to reach the 20-20-20 targets. The question is raised whether the international rules on civil liability provide sufficient protection to victims of nuclear

    2012-01-01

    We provide information on a non-trivial structure of phase space of the cubic nonlinear Schrödinger (NLS) on a three-edge star graph. We prove that, in contrast to the case of the standard NLS on the line, the energy associated with the cubic focusing Schrödinger equation on the three-edge star graph with a free (Kirchhoff) vertex does not attain a minimum value on any sphere of constant L 2 -norm. We moreover show that the only stationary state with prescribed L 2 -norm is indeed a saddle point. (fast track communication)

  2. Spectral energy distributions of T Tauri stars - disk flaring and limits on accretion

    International Nuclear Information System (INIS)

    Kenyon, S.J.; Hartmann, L.

    1987-01-01

    The Adams et al. (1987) conclusion that much of the IR excess emission in the spectral energy distribution of T Tauri stars arises from reprocessing of stellar radiation by a dusty circumstellar disk is presently supported by analyses conducted in light of various models of these stars' spectra. A low mass reprocessing disk can, however, produce these spectra as well as a massive accretion disk. The detection of possible boundary layer radiation in the optical and near-UV regions poses the strongest limits on accretion rates. Disk accretion in the T Tauri phase does not significantly modify stellar evolution. 85 references

  4. Nuclear fission: the tarnished star of our energy future

    International Nuclear Information System (INIS)

    1986-01-01

    The use of fission nuclear energy to fuel commercial electricity-generating facilities, once considered the answer to the world's energy dilemma, is facing serious financial problems and reduced demand. Although the technology to handle the necessary functions exists, construction errors and delays, extensive cost overruns, equipment malfunctions, operator errors, continual regulation and design changes, and concern about long-term wastes and their effects on the environment and human health are plaguing the industry. Research and development efforts continue worldwide to improve the technology in the areas of use and waste handling. Many people express the belief that nuclear fission is necessary to fill the void being created by the decline in availability of fossil fuels. This may be true without extensive efforts in conservation and the use of other energy forms. 26 references, 13 figures

  5. SPECTRAL ENERGY DISTRIBUTIONS OF YOUNG STARS IN IC 348: THE ROLE OF DISKS IN ANGULAR MOMENTUM EVOLUTION OF YOUNG, LOW-MASS STARS

    International Nuclear Information System (INIS)

    Le Blanc, Thompson S.; Stassun, Keivan G.; Covey, Kevin R.

    2011-01-01

    Theoretical work suggests that a young star's angular momentum content and rotation rate may be strongly influenced by magnetic interactions with its circumstellar disk. A generic prediction of these 'disk-locking' theories is that a disk-locked star will be forced to co-rotate with the Keplerian angular velocity of the inner edge of the disk; that is, the disk's inner-truncation radius should equal its co-rotation radius. These theories have also been interpreted to suggest a gross correlation between young stars' rotation periods and the structural properties of their circumstellar disks, such that slowly rotating stars possess close-in disks that enforce the star's slow rotation, whereas rapidly rotating stars possess anemic or evacuated inner disks that are unable to brake the stars and instead the stars spin up as they contract. To test these expectations, we model the spectral energy distributions (SEDs) of 33 young stars in IC 348 with known rotation periods and infrared excesses indicating the presence of circumstellar disks. For each star, we match the observed SED, typically sampling 0.6-8.0 μm, to a grid of 200,000 pre-computed star+disk radiative transfer models, from which we infer the disk's inner-truncation radius. We then compare this truncation radius to the disk's co-rotation radius, calculated from the star's measured rotation period. We do not find obvious differences in the disk truncation radii of slow rotators versus rapid rotators. This holds true both at the level of whether close-in disk material is present at all, and in analyzing the precise location of the inner disk edge relative to the co-rotation radius among the subset of stars with close-in disk material. One interpretation is that disk locking is unimportant for the IC 348 stars in our sample. Alternatively, if disk locking does operate, then it must operate on both the slow and rapid rotators, potentially producing both spin-up and spin-down torques, and the transition from the

    This study content analyses the energy content in the corporate report of top 30 Malaysian energy-intensive companies. Motivated by the gap among prior corporate social responsibility and environmental reporting studies in respect of energy, this study provides evidence of Malaysian companies’ initiative to reduce energy consumption. While the evidence suggests that not all 30 companies have reported energy-related information, the findings provide an overview on the response of energy intensive companies in relation to Malaysian government initiatives on energy.

    2010-01-01

    After having recalled the European environmental objectives (reduction of greenhouse gas emissions by 20%, improving energy efficiency by 20%, renewable energies representing at least 20% of the whole energy consumption), this report describes the recent and fast development of wind energy in France (installed power in 2009, still not much developed industry, ambitious projects, numerous tools) and worldwide (important growth in Europe and worldwide). It describes this development as a rather disordered one in terms of pricing, in terms of land planning and of preservation of landscapes, sites and other activities. It outlines some technical problems which are still to be solved: connection to the network, intermittent production and prediction issues. It briefly presents choices made in Denmark. Some issues are then discussed for a better controlled development: a strengthened public policy, a better acceptance by the population. The report finally questions the future for an offshore wind energy production: economical, technological, landscape, and legal issues, examples of foreign projects, presentation of some planned French projects

  9. Star/galaxy separation at faint magnitudes: Application to a simulated Dark Energy Survey

    Energy Technology Data Exchange (ETDEWEB)

    Soumagnac, M.T.; et al.

    2013-06-21

    We address the problem of separating stars from galaxies in future large photometric surveys. We focus our analysis on simulations of the Dark Energy Survey (DES). In the first part of the paper, we derive the science requirements on star/galaxy separation, for measurement of the cosmological parameters with the Gravitational Weak Lensing and Large Scale Structure probes. These requirements are dictated by the need to control both the statistical and systematic errors on the cosmological parameters, and by Point Spread Function calibration. We formulate the requirements in terms of the completeness and purity provided by a given star/galaxy classifier. In order to achieve these requirements at faint magnitudes, we propose a new method for star/galaxy separation in the second part of the paper. We first use Principal Component Analysis to outline the correlations between the objects parameters and extract from it the most relevant information. We then use the reduced set of parameters as input to an Artificial Neural Network. This multi-parameter approach improves upon purely morphometric classifiers (such as the classifier implemented in SExtractor), especially at faint magnitudes: it increases the purity by up to 20% for stars and by up to 12% for galaxies, at i-magnitude fainter than 23.

  12. Neutron stars as X-ray burst sources. II. Burst energy histograms and why they burst

    International Nuclear Information System (INIS)

    Baan, W.A.

    1979-01-01

    In this work we explore some of the implications of a model for X-ray burst sources where bursts are caused by Kruskal-Schwarzschild instabilities at the magnetopause of an accreting and rotating neutron star. A number of simplifying assumptions are made in order to test the model using observed burst-energy histograms for the rapid burster MXB 1730--335. The predicted histograms have a correct general shape, but it appears that other effects are important as well, and that mode competition, for instance, may suppress the histograms at high burst energies. An explanation is ventured for the enhancement in the histogram at the highest burst energies, which produces the bimodal shape in high accretion rate histograms. Quantitative criteria are given for deciding when accreting neutron stars are steady sources or burst sources, and these criteria are tested using the X-ray pulsars

  13. Energy transport in radially accreting white dwarf stars

    Energy Technology Data Exchange (ETDEWEB)

    Thompson, A.M.

    1986-10-01

    Some of the non-thermal energy transport processes which may be present in a white dwarf accretion column are examined and it is determined whether these could in any way contribute to a resolution of the soft X-ray puzzle. The first two Chapters of this Thesis constitute a review of the observations and proposed models for white dwarf accretion columns. In Chapter 3 we show that in Kuijpers and Pringle's original bombardment model of white dwarf accretion columns, in which the energy of the accreting material is deposited uniformly into a static atmosphere which then radiates the energy away as optically thin bremsstrahlung/line radiation, an incorrect Coulomb collisional timescale was used. In Chapter 4 we extend the calculations of Chapter 3 to include the effect of cyclotron radiation. It is concluded that a cyclotron cooled bombardment solution for a white dwarf accretion column may exist. We extend this calculation to derive a simple piecewise uniform temperature structure for such an accretion column, incorporating the effect of thermal conduction. In Chaper 5 we examine two of the non thermal emission mechanisms that might be present in white dwarf accretion columns:- non thermal Lyman-{alpha} emission and non thermal inverse bremsstrahlung emission. It is shown that neither would actually be sufficiently large to be detectable. In Chapter 6 some possible extensions to the work presented are suggested. (author).

    The world is facing significant growth in energy demand over the next several decades. Strategic in meeting this demand are the world-class energy resources concentrated along the Rocky Mountains and northern plains in Canada and the U.S., informally referred to as the Western Energy Corridor (WEC). The fossil energy resources in this region are rivaled only in a very few places in the world, and the proven uranium reserves are among the world's largest. Also concentrated in this region are renewable resources contributing to wind power, hydro power, bioenergy, geothermal energy, and solar energy. Substantial existing and planned energy infrastructure, including refineries, pipelines, electrical transmission lines, and rail lines provide access to these resources.

    1999-01-01

    We study the influence of a high density behaviour of the nuclear symmetry energy on a kaon condensation in neutron stars. We find that the symmetry energy typical for several realistic nuclear potentials, which decreases at high densities, inhibits kaon condensation for weaker kaon-nucleon couplings at any density. There exists a threshold coupling above which the kaon condensate forms at densities exceeding some critical value. This is in contrast to the case of rising symmetry energy, as e.g. for relativistic mean field models, when the kaon condensate can form for any coupling at a sufficiently high density. Properties of the condensate are also different in both cases. (author)

    The Star Fire Project is a joint SNLA/LLNL effort to develop a combined two-stage light-gas gun (2SLGG) and railgun into a three-stage hypervelocity launcher for equation-of-state (EOS) research. The 2SLGG is used to accelerate a projectile to a velocity of 6-9 km/s. The railgun serves as the third stage to further accelerate the projectile. The high injection velocity will minimize barrel ablation and armature contamination. Hydrogen is used as the injection gas and serves to reduce the probability of forming secondary arcs. VISAR is used for continuous precision projectile velocity measurement. This paper discusses the results of armature formation tests, the use of the railgun stage to increase projectile velocity, and armature diagnostic measurements

    Energy Smart Colorado is an energy efficiency program established in 2011 in the central mountain region of Colorado. The program was funded through a grant of $4.9 million, awarded in August 2010 by the U.S. Department of Energy’s Better Buildings Program. As primary grant recipient, Eagle County coordinated program activities, managed the budget, and reported results. Eagle County staff worked closely with local community education and outreach partner Eagle Valley Alliance for Sustainability (now Walking Mountains Science Center) to engage residents in the program. Sub-recipients Pitkin County and Gunnison County assigned local implementation of the program in their regions to their respective community efficiency organizations, Community Office for Resource Efficiency (CORE) in Pitkin County, and Office for Resource Efficiency (ORE) in Gunnison County. Utility partners contributed $166,600 to support Home Energy Assessments for their customers. Program staff opened Energy Resource Centers, engaged a network of qualified contractors, developed a work-flow, an enrollment website, a loan program, and a data management system to track results.

    The Ministry of Economic Affairs continues its task of observing and informing about the Croatian energy system. The review consists of the most recent and classified data on 1997 and the previous four years. Compared to previous year, in 1997 the total primary energy supply decreased by 1,3 percent. At the same time the gross domestic product increased by 6,5 percent, thus the energy intensity dropped, which is a positive trend. The energy intensity, the value showing the total energy consumed per unit of gross domestic product, exceeds the level realised by the Western European countries, but it is at the same time more favourable related to the transition economy countries. On the other hand, 1997 saw a decrease in the primary energy production by 8,9 percent, resulting from the decline in the production of natural gas, oil and coal, and naturally, unfavourable hydrological conditions. Thus, own supply dropped to 57 percent, the lowest recorded in the past five years. In 1997 the losses and operational consumption of energy decreased more than the non-energy consumption increased, but despite the decrease of the total primary energy supply there occurred an increase of final energy demand by total of 4,4 percent, 2,1 of which in general consumption, 5,5 in transport and 7,8 percent in industry. Apart from these data, the review considers all other relevant indicators showing a positive shift but leaving space for further improvements with the aim of achieving higher energy system efficiency

    International Nuclear Information System (INIS)

    1997-12-01

    The publication creates a condensed review of the state of affairs within our energy system. It includes the latest data for 1996, which were at the same time compared to the situations from the previous four years in order to achieve a more accurate insight into all the related problems. The relation of the gross domestic product (GDP) and the electric energy consumption illustrates the fact that the economic conditions are closely connected to the development of the energy sector. In 1996 the gross domestic product was 4.2% higher than in the year before and the electric energy consumption increased by approximately the same figure. It rose from the consumed 12958.0 GWh in 1995 to 12877.9 GWh in 1996, i.e. 4.2%. The total energy consumption in 1996 increased by entire 10.8%, amounting to 352.56 PJ, this predominantly being a result of growing hydro power and natural gas consumption. The immediate energy consumption grew by 8.3%, from 185.96 PJ in 1995 to 201.35 PJ in 1996. Apart from the data included in the review, there are also other presentations referring to the energy generation and consumption in Croatia. A special chapter comprises an analysis of oil and gas system, i.e. hydrocarbon and coal reserves as well as the capacities required for oil and gas processing and transportation. The attention was directed to positive environmental incentives, as the energy sector is responsible for more than 90% of all polluting substances. Apart from the economic and financial indices, the publication includes the prices for electric energy, natural gas and oil derivations as well as maps showing the route of the gas and JANAF systems and the transmission electric energy network. The review puts forward some positive achievements in the development of our energy sector, which create the basis for continued efforts in order to bring about the desired objectives. This will be realized by defining the legislation system and the institutions ensuring high-quality market

    The review consists of the most recent and settled data for the year 2000 as well as data for the five-years period. In 2000 total energy consumption decreased by 2.8 percent compared to the previous year. As at the same time the gross domestic product increased by 3.7 percent, energy intensity grew, thus presenting a positive change of trend . The energy intensity, the measurement showing the total energy consumption per unit of gross domestic product, exceeded the level realised by the Western European countries, but was still more favourable than in most transition countries. At the same time 2000 saw an decrease of primary energy generation by 1.7 percent but, as a consequence of extremely favourable hydrological conditions, with a decreased production of natural gas and oil. The supply from own sources remained 51 percent but the trend is expected to be negative in the following few years bearing in mind the condition of the gas and oil reserves, i.e. cessation of coal production in Istria. Only partly will the process be slowed down by the production of natural gas from the Northern Adriatic. Natural gas production grew by 6.8 percent compared to the previous year, causing the share of natural gas in energy production to exceed 32 percent. In 2000 the transformation losses fell by 11 percent, transportation and distribution losses fell by 6.7 percent and non-energy consumption by 2.4 percent, while energy sector own use rose by 1.4 percent.. The result of this was that, despite the increase of total energy production by 2.8 percent, final energy demand fell by only 0.2 percent, i.e. 1.5 percent in other sectors and transport, and 2.9 percent increase in industry. Apart from these data, the publication includes all other relevant indicators about our energy system, i.e. system capacities, energy source prices, environmental influence, etc

  13. Nuclear Statistical Equilibrium for compact stars: modelling the nuclear energy functional

    International Nuclear Information System (INIS)

    Aymard, Francois

    2015-01-01

    The core collapse supernova is one of the most powerful known phenomena in the universe. It results from the explosion of very massive stars after they have burnt all their fuel. The hot compact remnant, the so-called proto-neutron star, cools down to become an inert catalyzed neutron star. The dynamics and structure of compact stars, that is core collapse supernovae, proto-neutron stars and neutron stars, are still not fully understood and are currently under active research, in association with astrophysical observations and nuclear experiments. One of the key components for modelling compact stars concerns the Equation of State. The task of computing a complete realistic consistent Equation of State for all such stars is challenging because a wide range of densities, proton fractions and temperatures is spanned. This thesis deals with the microscopic modelling of the structure and internal composition of baryonic matter with nucleonic degrees of freedom in compact stars, in order to obtain a realistic unified Equation of State. In particular, we are interested in a formalism which can be applied both at sub-saturation and super-saturation densities, and which gives in the zero temperature limit results compatible with the microscopic Hartree-Fock-Bogoliubov theory with modern realistic effective interactions constrained on experimental nuclear data. For this purpose, we present, for sub-saturated matter, a Nuclear Statistical Equilibrium model which corresponds to a statistical superposition of finite configurations, the so-called Wigner-Seitz cells. Each cell contains a nucleus, or cluster, embedded in a homogeneous electron gas as well as a homogeneous neutron and proton gas. Within each cell, we investigate the different components of the nuclear energy of clusters in interaction with gases. The use of the nuclear mean-field theory for the description of both the clusters and the nucleon gas allows a theoretical consistency with the treatment at saturation

  14. Adaptive acoustic energy delivery to near and far fields using foldable, tessellated star transducers

    2017-05-01

    Methods of guiding acoustic energy arbitrarily through space have long relied on digital controls to meet performance needs. Yet, more recent attention to adaptive structures with unique spatial configurations has motivated mechanical signal processing (MSP) concepts that may not be subjected to the same functional and performance limitations as digital acoustic beamforming counterparts. The periodicity of repeatable structural reconfiguration enabled by origami-inspired tessellated architectures turns attention to foldable platforms as frameworks for MSP development. This research harnesses principles of MSP to study a tessellated, star-shaped acoustic transducer constituent that provides on-demand control of acoustic energy guiding via folding-induced shape reconfiguration. An analytical framework is established to probe the roles of mechanical and acoustic geometry on the far field directivity and near field focusing of sound energy. Following validation by experiments and verification by simulations, parametric studies are undertaken to uncover relations between constituent topology and acoustic energy delivery to arbitrary points in the free field. The adaptations enabled by folding of the star-shaped transducer reveal capability for restricting sound energy to angular regions in the far field while also introducing means to modulate sound energy by three orders-of-magnitude to locations near to the transducer surface. In addition, the modeling philosophy devised here provides a valuable approach to solve general sound radiation problems for foldable, tessellated acoustic transducer constituents of arbitrary geometry.

    The review, in its own recognisable way, consists of the most recent and settled data for the year 2001, i.e. for the period from 1996 until 2001. We have, however, added data appertaining to a longer time period together with future expectations with the aim of an easier insight into long-term prospects. In 2001 total primary energy supply increased by 3.3 percent compared to the preceding year. Owing to the simultaneous growth of the gross domestic product by 4.1 percent, energy intensity decreased and consequently a positive trend continues. Energy intensity, which expressed the total energy consumed per unit of gross domestic product, exceeds the realised level of the developed European countries, but it is still more favourable than in the majority of transition countries. We would particularly like to stress the fact about the recorded growth of primary energy production by 7 percent, which in 2001 occurred partly as the consequence of favourable hydrological conditions and partly of a considerable increase in natural gas production. Supply from own sources grew to 52.8 percent. In 2001, natural gas production in the structure of the domestic production amounted to more than 36 percent. Energy import recorded an increase of 2.2 percent, whereby the portion of the imported crude oil was 65 percent. In 2001 transformation losses increased by 15.9 percent, transportation and distribution losses by 22.6 percent, energy sector own use by 10.3 percent, while non-energy consumption decreased by 15 percent. This brought about the situation that, together with the above mentioned growth of the total energy consumed of 3.3 percent, final demand grew by 2.6 percent - 2.3 percent in other sectors, 1.1 percent in traffic with the simultaneous increase in industry of 5.1 percent. Apart from these data, the publication comprises other interesting facts about our energy system, its capacities, energy source prices and environmental impact

    Bonner, B.E.; Mutchler, G.S.

    1992-01-01

    We report here oil the progress that we made for the nine months beginning October 1, 1991 for DOE Grant No. DE-FG05-87ER40309. The report covers the third year of a three year grant. Since we are submitting an accompanying Grant Renewal Proposal, we provide in this report more background information than usual for the different projects. The theme that unites the experiments undertaken by the Bonner Lab Medium Energy Group is a determination to understand in detail the many facets and manifestations of the strong interaction, that which is now referred to as nonperturbative QCD. Whether we are investigating the question of just what does carry the spin of baryons, or the extent of the validity of the SU(6) wavefunctions for the excited hyperons (as will be measured in our CEBAF experiment), or questions associated with the formation of a new state of matter predicted by QCD (the subject of AGS bar p experiment E854, AGS heavy ion experiment E810, as-well as the approved STAR experiment at RHIC), - all these projects share this common goal. FNAL E683 may well open a new field of investigation in nuclear physics: That of just how colored quarks and gluons interact with nuclear matter as they traverse nuclei of different-sizes. In most all of the experiments mentioned, above, the Bonner Lab Group is playing major leadership roles as well as doing a big fraction of the hard work that such experiments require. We use many of the facilities that are available to the intermediate energy physics community and we use our expertise to design and fabricate the detectors and instrumentation that are required to perform the measurements which we decide to do. The format we follow in the Progress Report is,to provide a concise, but fairly complete write-up on each project. The publications listed in Section In give much greater detail on many of the projects. The aim in this report is to focus on the physics goals, the results, and their significance

    The concept, implementation, and long-range goals of a Supportability Trend Analysis and Reporting System (STARS) for the National Space Transportation System (NSTS) are discussed. The requirement was established as a direct result of the recommendations of the Rogers Commission investigation of the circumstances of the Space Shuttle Challenger accident. STARS outlines the requirements for the supportability-trend data collection, analysis, and reporting requirements that each of the project offices supporting the Space Shuttle are required to provide to the NSTS program office. STARS data give the historic and predictive logistics information necessary for all levels of NSTS management to make safe and cost-effective decisions concerning the smooth flow of Space Shuttle turnaround.

    1992-09-01

    Energy security was identified in the National Energy Strategy (NES) as a major issue for the Department of Energy (DOE). As part of a process designed by the DOE to identify technologies important to implementing the NES, an expert working group was convened to consider which technologies can best contribute to reducing the nation's economic vulnerability to future disruptions of world oil supplies, the working definition of energy security. Other working groups were established to deal with economic growth, environmental quality, and technical foundations. Energy Security working group members were chosen to represent as broad a spectrum of energy supply and end-use technologies as possible and were selected for their established reputations as experienced experts with an ability to be objective. The time available for this evaluation was very short. The group evaluated technologies using criteria taken from the NES which can be summarized for energy security as follows: diversifying sources of world oil supply so as to decrease the increasing monopoly status of the Persian Gulf region; reducing the importance of oil use in the US economy to diminish the impact of future disruptions in oil supply; and increasing the preparedness of the US to deal with oil supply disruptions by having alternatives available at a known price. The result of the first phase of the evaluation process was the identification of technology groups determined to be clearly important for reducing US vulnerability to oil supply disruptions. The important technologies were mostly within the high leverage areas of oil and gas supply and transportation demand but also included hydrogen utilization, biomass, diversion resistant nuclear power, and substitute industrial feedstocks.

  20. Low Density Symmetry Energy Effects and the Neutron Star Crust Properties

    2010-01-01

    The form of the nuclear symmetry energy E s around saturation point density leads to a different crust-core transition point in the neutron star and affects the crust properties. We show that the knowledge of E s close to the saturation point is not sufficient to determine the position of the transition point and the very low density behaviour is required. We also claim that crust properties are strongly influenced by the very high density behaviour of E s , so in order to conclude about the form of low density part of the symmetry energy from astrophysical data one must isolate properly the high density part.

    A number of observed phenomena associated with individual neutron star systems or neutron star populations find explanations in models in which the neutron star crust plays an important role. We review recent work examining the sensitivity to the slope of the symmetry energy L of such models, and constraints extracted on L from confronting them with observations. We focus on six sets of observations and proposed explanations: (i) The cooling rate of the neutron star in Cassiopeia A, confronting cooling models which include enhanced cooling in the nuclear pasta regions of the inner crust; (ii) the upper limit of the observed periods of young X-ray pulsars, confronting models of magnetic field decay in the crust caused by the high resistivity of the nuclear pasta layer; (iii) glitches from the Vela pulsar, confronting the paradigm that they arise due to a sudden recoupling of the crustal neutron superfluid to the crustal lattice after a period during which they were decoupled due to vortex pinning; (iv) the frequencies of quasi-periodic oscillations in the X-ray tail of light curves from giant flares from soft gamma-ray repeaters, confronting models of torsional crust oscillations; (v) the upper limit on the frequency to which millisecond pulsars can be spun-up due to accretion from a binary companion, confronting models of the r-mode instability arising above a threshold frequency determined in part by the viscous dissipation timescale at the crust-core boundary; and (vi) the observations of precursor electromagnetic flares a few seconds before short gamma-ray bursts, confronting a model of crust shattering caused by resonant excitation of a crustal oscillation mode by the tidal gravitational field of a companion neutron star just before merger.

    2018-01-01

    We present a multiwavelength study of 30 Galactic massive star-forming regions. We fit multicomponent dust, blackbody, and power-law continuum models to 3.6 µm through 10 mm spectral energy distributions obtained from Spitzer, MSX, IRAS, Herschel, and Planck archival survey data. Averaged across our sample, ~20% of Lyman continuum photons emitted by massive stars are absorbed by dust before contributing to the ionization of H II regions, while ~50% of the stellar bolometric luminosity is absorbed and reprocessed by dust in the H II regions and surrounding photodissociation regions. The most luminous, infrared-bright regions that fully sample the upper stellar initial mass function (ionizing photon rates NC ≥ 1050 s–1 and total infrared luminosity LTIR ≥ 106.8 L⊙) have higher percentages of absorbed Lyman continuum photons (~40%) and dust-reprocessed starlight (~80%). The monochromatic 70-µm luminosity L70 is linearly correlated with LTIR, and on average L70/LTIR = 50%, in good agreement with extragalactic studies. Calibrated against the known massive stellar content in our sampled H II regions, we find that star formation rates based on L70 are in reasonably good agreement with extragalactic calibrations, when corrected for the smaller physical sizes of the Galactic regions. We caution that absorption of Lyman continuum photons prior to contributing to the observed ionizing photon rate may reduce the attenuation-corrected Hα emission, systematically biasing extragalactic calibrations toward lower star formation rates when applied to spatially-resolved studies of obscured star formation.This work was supported by the National Science Foundation under award CAREER-1454333.

    The primary objective for the Fairbanks Geothermal Energy Project is to provide another source of base-load renewable energy in the Fairbanks North Star Borough (FNSB). To accomplish this, Chena Hot Springs Resort (Chena) drilled a re-injection well to 2700 feet and a production well to 2500 feet. The re-injection well allows a greater flow of water to directly replace the water removed from the warmest fractures in the geothermal reservoir. The new production will provide access to warmer temperature water in greater quantities.

    The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains. Coal and coke are currently the primary fuels for the sector, supplanting the dominance of natural gas in the 1970s. Most recently, there is a slight increase in the use of waste fuels, including tires. Between 1970 and 1999, primary physical energy intensity for cement production dropped 1 percent/year from 7.3 MBtu/short ton to 5.3 MBtu/short ton. Carbon dioxide intensity due to fuel consumption and raw material calcination dropped 16 percent, from 609 lb. C/ton of cement (0.31 tC/tonne) to 510 lb. C/ton cement (0.26 tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement. The relatively high share of wet-process plants (25 percent of clinker production in 1999 in the U.S.) suggests the existence of a considerable potential, when compared to other industrialized countries. We examined over 40 energy efficient technologies and measures and estimated energy savings, carbon dioxide savings, investment costs, and operation and maintenance costs for each of the measures. The report describes the measures and experiences of cement plants around the wold with these practices and technologies. Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists.

    Power System planning tools are being used today to simulate systems that are far larger and more complex than just a few years ago. Advances in renewable technologies and more pervasive control technology are driving planning engineers to analyze an increasing number of scenarios and system models with much more detailed network representations. Although the speed of individual CPU’s has increased roughly according to Moore’s Law, the requirements for advanced models, increased system sizes, and larger sensitivities have outstripped CPU performance. This computational dilemma has reached a critical point and the industry needs to develop the technology to accurately model the power system of the future. The hpc4energy incubator program provided a unique opportunity to leverage the HPC resources available to LLNL and the power systems domain expertise of GE Energy to enhance the GE Concorda PSLF software. Well over 500 users worldwide, including all of the major California electric utilities, rely on Concorda PSLF software for their power flow and dynamics. This pilot project demonstrated that the GE Concorda PSLF software can perform contingency analysis in a massively parallel environment to significantly reduce the time to results. An analysis with 4,127 contingencies that would take 24 days on a single core was reduced to 24 minutes when run on 4,217 cores. A secondary goal of this project was to develop and test modeling techniques that will expand the computational capability of PSLF to efficiently deal with systems sizes greater than 150,000 buses. Toward this goal the matrix reordering implementation time was sped up 9.5 times by optimizing the code and introducing threading.

    High-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 to 79 keV, extending the sensitivity of focusing far beyond the 10 keV high-energy cutoff achieved by all previous X-ray satellites. The inherently low background associated with concentrating the X-ray light enables NuSTAR to probe the hard X-ray sky with a more than 100-fold improvement in sensitivity over the collimated or coded mask instruments that have operated in this bandpass. Using its unprecedented combination of sensitivity and spatial and spectral resolution, NuSTAR will pursue five primary scientific objectives: (1) probe obscured active galactic nucleus (AGN) activity out to thepeak epoch of galaxy assembly in the universe (at z 2) by surveying selected regions of the sky; (2) study the population of hard X-ray-emitting compact objects in the Galaxy by mapping the central regions of the Milky Way; (3) study the non-thermal radiation in young supernova remnants, both the hard X-ray continuum and the emission from the radioactive element 44Ti; (4) observe blazars contemporaneously with ground-based radio, optical, and TeV telescopes, as well as with Fermi and Swift, to constrain the structure of AGN jets; and (5) observe line and continuum emission from core-collapse supernovae in the Local Group, and from nearby Type Ia events, to constrain explosion models. During its baseline two-year mission, NuSTAR will also undertake a broad program of targeted observations. The observatory consists of two co-aligned grazing-incidence X-ray telescopes pointed at celestial targets by a three-axis stabilized spacecraft. Deployed into a 600 km, near-circular, 6 inclination orbit, the observatory has now completed commissioning, and is performing consistent with pre-launch expectations. NuSTAR is now executing its primary science mission, and with an expected orbit lifetime of 10 yr, we anticipate proposing a guest investigator program, to begin in late 2014.

    A stellar model in which density in the undisturbed conducting-gas medium is assumed to obey a power law is considered. Similarity solutions for central explosion in radiating stars have been obtained under the assumption of isothermal-shock conditions. For the existence of self-similar character, it has been assumed that both radiation pressure and energy are negligible. The results of numerical calculations for different models are illustrated through graphs. Moreover, a comparative study has been made between the results in ordinary gasdynamics and those obtained in magnetogasdynamics

    In the context of the the International Conference on the climatic changes at La Haye, the projects of the nuclear industry reorganizing and the network energies market deregulation, the french government organized some discussions on the energy. Four subjects have been chosen to answer to the following four questions: What about the energy supply and demand in the future? How take up the environmental challenges of the energy? What is the future of the electro- nuclear industry? Towards which new economic organization of network energies will emerge the deregulation of the electric power and gas market? This document presents the conclusions of these four thematic meetings. (A.L.B.)

    A review of future trends of energy consumption shows that, in the absence of an active energy policy which promotes energy efficiency, energy consumption will increase as a whole by approximately 6.8% by 2012 continuing to raise after this period.. This result hides large differences between the different sources of energy (mainly heat, fuels and electricity) and between the different sectors - transport, industry, buildings etc. It is therefore clear that a strong energy policy is needed to counterbalance the expected increase in energy consumption in all sectors, with emphasis on measures in the building sector (both residential and tertiary) and in the transport sector. Furthermore improvements in the district heating sector are also essential to prevent further disconnection from district heating and a shift to other means of heating. A review of the main barriers to energy efficiency leads to the conclusion that while significant changes are needed in the regulatory framework, the lack of access to finance and the general lack of awareness about existing technologies and best practice represent the greatest barriers. In order to evaluate the success of energy. In a few studies available from past 2-3 years the calculation of low and high targets for energy policy was elaborated. The low targets would represent about 11% - 12% reduction in overall energy consumption. The high targets would represent a 13% - 15% reduction in overall energy consumption. Policy instruments have been identified which can turn energy efficiency into one of the driving forces of the overall economic and development strategy of the country. Some of these instruments deal with general issues such as general policy issues, regulatory and legal aspects, the institutional framework and fiscal, taxation and pricing policy. They are designed to improve the present conditions and would use only a limited part of the available public budget. The state budget dedicated to energy issues will

    The Energy Program emphasizes applied R ampersand D for energy technologies that will be important to the US in the next fifty years and which may be important long after that. Historically, we have focused on coal gasification; the development of alternative liquid fuels from oil shale, coal, and natural gas; transportation uses of electric power from refuelable batteries; geothermal energy; and support of nuclear energy through the development of new technologies for the disposal of high-level nuclear waste. Our current program addresses three objectives of the National Energy Strategy: (1) To enhance energy security by ensuring stable costs, increasing energy supplies, and developing alternatives to Middle East oil. (2) To improve environmental quality by implementing energy technologies that effect better air and water quality, improve land use, and protect global environmental systems. (3) To encourage economic growth through technologies that reduce the costs of energy production, storage, transport, transmission, and distribution; promote efficiency by reducing costs and end-user services; and strengthen resiliency and flexibility of energy systems. We have just begun a major program to commercialize the technology to extract oil from the large US reserves (greater than 700 billion barrels) of oil shale. Perhaps the single greatest barrier to the public acceptance of nuclear power is the perceived lack of a technical solution to the permanent disposal of wastes. We have developed new concepts that are aimed at improving the likelihood of technical assurance of long-term containment

    The Danish Government's long-term energy strategy follows up on the political agreement of 29 March 2004. The energy strategy is a coherent formulation of the Government's long-term energy policy. The pivotal point for the energy strategy is liberalized energy markets and market based tools for obtaining goals such as efficiency, security of supply and environment. The focus is increasingly on the substantial business potential within development of new and more efficient energy technology, in which Denmark takes up several globally strong positions. Furthermore, transportation energy consumption has been included directly in an energy strategy for the first time. At the same time as the energy strategy is presented, a summarizing background report from the Danish Energy Agency with facts, analyses and evaluations is published, as well as a report from energinet.dk that summarizes the system responsibilities' input to that part of the energy strategy that deals with power infrastructure.

  3. Transportation radiological emergency preparedness: STAR 95 Exercise final report

    International Nuclear Information System (INIS)

    1998-01-01

    Emergency response for a transportation accident involving radiological materials, while not inherently difficult, presents a challenge for several reasons. These accidents, although they can occur anywhere, are rare. Also, although the health consequences are usually slight, accidents involving radioactive materials generally cause a great deal of concern, both for the emergency responders and the general public. How can communities be prepared for an event that requires some technical knowledge, but is so rare that it will never occur in most areas, without expending an effort disproportionate to the actual risk? How can one appropriately deal with an event that may cause excessive public concern? These questions are at the heart of the preparedness issues this program addressed. The overall goal of the Transportation Emergency Preparedness Program was to establish the framework for a coordinated response by all levels of government to a transportation accident involving radioactive material. The Program involved both preparedness activities and the development, conduct and evaluation of a field exercise in Saratoga County, New York. This Report concentrates on the functional activities, lessons learned, recommendations, and action plans for improving preparedness and response to a transportation accident involving radioactive materials

    In recent years, the Economic Community of West African States (ECOWAS), comprising 15 Member States, it has emerged as one of the most active and dynamic regional economic communities on the African continent. Expanding access to modern, reliable, and affordable energy services is a key priority, prompting inter-state cooperation in crucial areas including capacity building, policy development and implementation, and investment. Recognising the critical role that sustainable energy plays in catalysing social, economic, and industrial development across the region, ECOWAS Member States formally inaugurated the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE) in 2010 to 'contribute to the sustainable economic, social and environmental development of West Africa by improving access to modern, reliable and affordable energy services, energy security and reduction of energy related externalities'. Drawing on data from the ECOWAS Observatory for Renewable Energy and Energy Efficiency (ECOWREX) and a network of contributors and researchers across the region, the ECOWAS Renewable Energy and Energy Efficiency Status Report supports ECREEE's efforts to increase the deployment of renewable energy and energy efficiency in West Africa by providing a comprehensive regional review of renewable energy and energy efficiency developments, evolving policy landscapes, market trends and related activities, investments in renewable energy and off-grid energy solutions, and the crucial nexus between energy access and gender

  9. Symmetry energy and neutron star properties in the saturated Nambu–Jona-Lasinio model

    Directory of Open Access Journals (Sweden)

    Si-Na Wei

    2016-12-01

    Full Text Available In this work, we adopt the Nambu–Jona-Lasinio (NJL model that ensures the nuclear matter saturation properties to study the density dependence of the symmetry energy. With the interactions constrained by the chiral symmetry, the symmetry energy shows novel characters different from those in conventional mean-field models. First, the negative symmetry energy at high densities that is absent in relativistic mean-field (RMF models can be obtained in the RMF approximation by introducing a chiral isovector–vector interaction, although it would be ruled out by the neutron star (NS stability. Second, with the inclusion of the isovector–scalar interaction the symmetry energy exhibits a general softening at high densities even for the large slope parameter of the symmetry energy. The NS properties obtained in the present NJL model can be in accord with the observations. The NS maximum mass obtained with various isovector–scalar couplings and momentum cutoffs is well above the 2M⊙, and the NS radius obtained well meets the limits extracted from recent measurements. In particular, the significant reduction of the canonical NS radius occurs with the moderate decrease of the slope of the symmetry energy.

    Firms offering a Green electricity product have discovered that residential customers are willing to pay extra for the assurance that their electricity is generated through the use of non-polluting or renewable resources. This research investigated the market potential for Green energy at the next level of the energy consuming chain, commercial establishments at which small and medium sized businesses interface with customers. Green energy is proving to be an attractive proposition to some consumers in the residential marketplace. Is there a possibility that Green energy can also be sold to commercial enterprises? This research project sought to answer this question and to investigate the factors that might lead small business people to opt for Green. Answers to these questions will help energy companies target the businesses most likely to accept Green power with the right product set and product features

    Transverse energy (E T ) has been measured with both of its components, namely hadronic (E T had ) and electromagnetic (E T em ) in a common phase space at mid-rapidity for 62.4 GeV Au+Au collisions by the STAR experiment. E T production with centrality and √S NN is studied with similar measurements from SPS to RHIC and is compared with a final state gluon saturation model (EKRT). The most striking feature is the observation of a nearly constant value of E T /N ch ∼ 0.8 GeV from AGS, SPS to RHIC. The initial energy density estimated by the boost-invariant Bjorken hydrodynamic model, is well above the critical density for a deconfined matter of quarks and gluons predicted by lattice QCD calculations.

  12. Constraints on the symmetry energy from neutron star equation of state

    CERN Document Server

    Miyazaki, K

    2006-01-01

    We develop an equation of state (EOS) for neutron star (NS) matter, which forbids the direct URCA cooling and satisfies the recent information on the mass and the radius, simultaneously. At sub-saturation densities, the symmetry energy of the EOS is well described by a function E_{sym}(\\rho)=31.6(\\rho/\\rho_0)^{\\gamma} with 0.70\\leq\\gamma\\leq0.77. This constraint on the density dependence of the symmetry energy is much severer than that obtained from the analysis of the isospin diffusion date in heavy-ion collisions. Consequently, we can obtain the valuable information on nuclear matter from the astrophysical observations of NSs.

    Fossil fuels provide about 80% of the global energy demand, and this will continue to be the situation for decades to come. In the European Community we are facing two major energy challenges. The first is sustainability, and the second is security of supply, since Europe is becoming more dependent on imported fuels. These challenges are the starting point for the present Risoe Energy Report 6. It gives an overview of the energy scene together with trends and emerging energy technologies. The report presents status and trends for energy technologies seen from a Danish and European perspective from three points of view: security of supply, climate change and industrial perspectives. The report addresses energy supply technologies, efficiency improvements and transport. The report is volume 6 in a series of reports covering energy issues at global, regional and national levels. The individual chapters of the report have been written by staff members from the Technical University of Denmark and Risoe National Laboratory together with leading Danish and international experts. The report is based on the latest research results from Risoe National Laboratory, Technical University of Denmark, together with available internationally recognized scientific material, and is fully referenced and refereed by renowned experts. Information on current developments is taken from the most up-to-date and authoritative sources available. Our target groups are colleagues, collaborating partners, customers, funding organizations, the Danish government and international organizations including the European Union, the International Energy Agency and the United Nations.

    1979-01-01

    With the help of cost-benefit calculations which include also the - to a great extent - neglected external resp. social costs the team of authors of the Havard Businees School conclude that energy conservation as well as alternative energies as solar energy are the most important energy sources of the future - a conclusion which clearly contradicts the present prevailing opinion according to which the expansion of energy consumption and the improvement of power supply by nuclear power plants are indispensable for the securing of economic growth and the economic structure. Although the authors keep up an option for nuclear energy (as it may perhaps be possible to solve the problem of radioactive waste disposal) they put forward the sober statement that - last not least because of its questionable economic efficiency - nuclear power cannot be a solution to energy crisis for the rest of the century, let alone to the politically precarious dependence of the Western Countries on the Saudi-Arabic import oil. The Havard Analysis is based on the latest numerical data and it is not only valid for the USA. It shall have even more impact for a country like the Federal Republic of Germany which is short of raw material. Therefore the American figures are put in relation to the German situation in an additional chapter. (orig./UA) [de

    FU Orionis stars (FUors) are eruptive pre-main sequence objects thought to represent quasi-periodic or recurring stages of enhanced accretion during the low-mass star-forming process. We characterize the sample of known and candidate FUors in a homogeneous and consistent way, deriving stellar and circumstellar parameters for each object. We emphasize the analysis in those parameters that are supposed to vary during the FUor stage. We modeled the spectral energy distributions of 24 of the 26 currently known FUors, using the radiative transfer code of Whitney et al. We compare our models with those obtained by Robitaille et al. for Taurus class II and I sources in quiescence periods by calculating the cumulative distribution of the different parameters. FUors have more massive disks: we find that ∼80% of the disks in FUors are more massive than any Taurus class II and I sources in the sample. Median values for the disk mass accretion rates are ∼10{sup –7} M {sub ☉} yr{sup –1} versus ∼10{sup –5} M {sub ☉} yr{sup –1} for standard young stellar objects (YSOs) and FUors, respectively. While the distributions of envelope mass accretion rates for class I FUors and standard class I objects are similar, FUors, on average, have higher envelope mass accretion rates than standard class II and class I sources. Most FUors (∼70%) have envelope mass accretion rates above 10{sup –7} M {sub ☉} yr{sup –1}. In contrast, 60% of the classical YSO sample has an accretion rate below this value. Our results support the current scenario in which changes experimented by the circumstellar disk explain the observed properties of these stars. However, the increase in the disk mass accretion rate is smaller than theoretically predicted, although in good agreement with previous determinations.

    Full Text Available Tourism is the sector of the global economy that has grown faster, in such way that the United Nations World Tourism Organization (UNWTO predicts a global average annual growth between 1995 and 2020, around 4.1%. This growth should contribute to a sustainable development and, be accompanied by environmental awareness of all stakeholders, and strategies of change pointing towards the preservation of environment, so as not to endanger the natural resources of future generations. Energy Management in tourism is the central theme of this research. The setting was 4 and 5 star hotels in Algarve, the most important tourist destination of Portugal. The main objectives of the study were to assess the current state of energy management in those hotels, understand the policies and strategies followed to optimize energy management, and analyze best practices. Results show a higher level of implementation of practices directly related to the optimization of energy than those related to reducing environmental impacts. In general, respondents consider that energy management is part of the concerns of those responsible for the hotels, the level of implementation of good practices in this area is high (78% and that both employees and tourists attach great importance to this issue.

The estimates are developed in the State Energy Data System (SEDS), which is maintained and operated by the Energy Information Administration (EIA). The goal in maintaining SEDS is to create historical time series of energy consumption by State that are defined as consistently as possible over time and across sectors. SEDS exists for two principal reasons: (1) to provide State energy consumption estimates to the Government, policy makers, and the public; and (2) to provide the historical series necessary for EIA's energy models

    We present NuSTAR observations of Vela X-1, a persistent, yet highly variable, neutron star high-mass X-ray binary (HMXB). Two observations were taken at similar orbital phases but separated by nearly a year. They show very different 3-79 keV flux levels as well as strong variability during each observation, covering almost one order of magnitude in flux. These observations allow, for the first time ever, investigations on kilo-second time-scales of how the centroid energies of cyclotron resonant scattering features (CRSFs) depend on flux for a persistent HMXB. We find that the line energy of the harmonic CRSF is correlated with flux, as expected in the sub-critical accretion regime. We argue that Vela X-1 has a very narrow accretion column with a radius of around 0.4 km that sustains a Coulomb interaction dominated shock at the observed luminosities of L {sub x} ∼ 3 × 10{sup 36} erg s{sup –1}. Besides the prominent harmonic line at 55 keV the fundamental line around 25 keV is clearly detected. We find that the strengths of the two CRSFs are anti-correlated, which we explain by photon spawning. This anti-correlation is a possible explanation for the debate about the existence of the fundamental line. The ratio of the line energies is variable with time and deviates significantly from 2.0, also a possible consequence of photon spawning, which changes the shape of the line. During the second observation, Vela X-1 showed a short off-state in which the power-law softened and a cut-off was no longer measurable. It is likely that the source switched to a different accretion regime at these low mass accretion rates, explaining the drastic change in spectral shape.

    World events significantly shaped the energy issue area work in 1991. The Iraqi war and oil disruption brought our oil pricing, national energy strategy, conservation, electricity supply, and alternative motor fuels work to the forefront. The collapse of Communism also stimulated greater congressional interest in how best to manage our nuclear weapons complex. This effort led the debate on the future needs and technology of weapons facilities, while also providing thoughtful insights on the $200 billion environmental cleanup effort. This paper includes information on these and other U.S. General Accounting Office (GAO) documents directly related to energy that were issued between January and December 1991. Highlights of this paper include: Nuclear waste, Electricity supply, Nuclear science, and Nuclear safety and health

  10. Geopressured energy availability. Final report

    1980-07-01

    Near- and long-term prospects that geopressured/geothermal energy sources could become a viable alternative fuel for electric power generation were investigated. Technical questions of producibility and power generation were included, as well as economic and environmental considerations. The investigators relied heavily on the existing body of information, particularly in geotechnical areas. Statistical methods were used where possible to establish probable production values. Potentially productive geopressured sediments have been identified in twenty specific on-shore fairways in Louisiana and Texas. A total of 232 trillion cubic feet (TCF) of dissolved methane and 367 x 10/sup 15/ Btu (367 quads) of thermal energy may be contained in the water within the sandstone in these formations. Reasonable predictions of the significant reservoir parameters indicate that a maximum of 7.6 TCF methane and 12.6 quads of thermal energy may be producible from these potential reservoirs.

    We present FIR [50-300 μm]–CO luminosity relations (i.e., log L{sub FIR}=αlog L{sub CO}{sup ′}+β) for the full CO rotational ladder from J = 1-0 up to J = 13-12 for a sample of 62 local (z ≤ 0.1) (Ultra) Luminous Infrared Galaxies (LIRGs; L {sub IR[8-1000} {sub μm]} > 10{sup 11} L {sub ☉}) using data from Herschel SPIRE-FTS and ground-based telescopes. We extend our sample to high redshifts (z > 1) by including 35 submillimeter selected dusty star forming galaxies from the literature with robust CO observations, and sufficiently well-sampled FIR/submillimeter spectral energy distributions (SEDs), so that accurate FIR luminosities can be determined. The addition of luminous starbursts at high redshifts enlarge the range of the FIR–CO luminosity relations toward the high-IR-luminosity end, while also significantly increasing the small amount of mid-J/high-J CO line data (J = 5-4 and higher) that was available prior to Herschel. This new data set (both in terms of IR luminosity and J-ladder) reveals linear FIR–CO luminosity relations (i.e., α ≅ 1) for J = 1-0 up to J = 5-4, with a nearly constant normalization (β ∼ 2). In the simplest physical scenario, this is expected from the (also) linear FIR–(molecular line) relations recently found for the dense gas tracer lines (HCN and CS), as long as the dense gas mass fraction does not vary strongly within our (merger/starburst)-dominated sample. However, from J = 6-5 and up to the J = 13-12 transition, we find an increasingly sublinear slope and higher normalization constant with increasing J. We argue that these are caused by a warm (∼100 K) and dense (>10{sup 4} cm{sup –3}) gas component whose thermal state is unlikely to be maintained by star-formation-powered far-UV radiation fields (and thus is no longer directly tied to the star formation rate). We suggest that mechanical heating (e.g., supernova-driven turbulence and shocks), and not cosmic rays, is the more likely source of energy for

    We combine Herschel-Photodetector Array Camera and Spectrometer (PACS) data from the PACS Evolutionary Probe (PEP) program with Spitzer 24 {mu}m and 16 {mu}m photometry and ultra deep Infrared Spectrograph (IRS) mid-infrared spectra to measure the mid- to far-infrared spectral energy distribution (SED) of 0.7 < z < 2.5 normal star-forming galaxies (SFGs) around the main sequence (the redshift-dependent relation of star formation rate (SFR) and stellar mass). Our very deep data confirm from individual far-infrared detections that z {approx} 2 SFRs are overestimated if based on 24 {mu}m fluxes and SED templates that are calibrated via local trends with luminosity. Galaxies with similar ratios of rest-frame {nu}L{sub {nu}}(8) to 8-1000 {mu}m infrared luminosity (LIR) tend to lie along lines of constant offset from the main sequence. We explore the relation between SED shape and offset in specific star formation rate (SSFR) from the redshift-dependent main sequence. Main-sequence galaxies tend to have a similar {nu}L{sub {nu}}(8)/LIR regardless of LIR and redshift, up to z {approx} 2.5, and {nu}L{sub {nu}}(8)/LIR decreases with increasing offset above the main sequence in a consistent way at the studied redshifts. We provide a redshift-independent calibration of SED templates in the range of 8-60 {mu}m as a function of {Delta}log(SSFR) offset from the main sequence. Redshift dependency enters only through the evolution of the main sequence with time. Ultra deep IRS spectra match these SED trends well and verify that they are mostly due to a change in ratio of polycyclic aromatic hydrocarbon (PAH) to LIR rather than continua of hidden active galactic nuclei (AGNs). Alternatively, we discuss the dependence of {nu}L{sub {nu}}(8)/LIR on LIR. The same {nu}L{sub {nu}}(8)/LIR is reached at increasingly higher LIR at higher redshift, with shifts relative to local by 0.5 and 0.8 dex in log(LIR) at redshifts z {approx} 1 and z {approx} 2.

    Full Text Available In this paper we report the measurements of the various moments mean (M, standard deviation (σ skewness (S and kurtosis (κ of the net-Kaon multiplicity distribution at midrapidity from Au+Au collisions at √sNN = 7.7 to 200 GeV in the STAR experiment at RHIC in an effort to locate the critical point in the QCD phase diagram. These moments and their products are related to the thermodynamic susceptibilities of conserved quantities such as net baryon number, net charge, and net strangeness as also to the correlation length of the system. A non-monotonic behavior of these variable indicate the presence of the critical point. In this work we also present the moments products Sσ, κσ2 of net-Kaon multiplicity distribution as a function of collision centrality and energies. The energy and the centrality dependence of higher moments of net-Kaons and their products have been compared with it0s Poisson expectation and with simulations from AMPT which does not include the critical point. From the measurement at all seven available beam energies, we find no evidence for a critical point in the QCD phase diagram for √sNN below 200 GeV.

    This report first gives an overview of the energy system by presenting the determining factors of energy demand and of CO 2 emissions per sector (housing and office building, transport, industry, agriculture, forestry and biomass), by analysing energy systems and CO 2 emissions (energy sources, energy vectors, networks and storage, energy and CO 2 assessment for France), and by describing the guidelines of the scenarios proposed by ANCRE. The three main scenarios are characterized by a stronger sobriety, an electricity-based de-carbonation (with a variant based on nuclear and renewable energies), and diversified vectors. They are notably compared to a trend-based reference scenario. Results are discussed in terms of energy consumption (primary and final energy, consumption by the different sectors), of energy production and CO 2 emissions. Scenarios are assessed in terms of economic, environmental and societal, political and strategic criteria. Some consequences for research topics and funding are identified

  2. Shedding Light on the EOS-Gravity Degeneracy and Constraining the Nuclear Symmetry Energy from the Gravitational Binding Energy of Neutron Stars

    Directory of Open Access Journals (Sweden)

    He Xiao-Tao

    2016-01-01

    Full Text Available A thorough understanding of properties of neutron stars requires both a reliable knowledge of the equation of state (EOS of super-dense nuclear matter and the strong-field gravity theories simultaneously. To provide information that may help break this EOS-gravity degeneracy, we investigate effects of nuclear symmetry energy on the gravitational binding energy of neutron stars within GR and the scalar-tensor subset of alternative gravity models. We focus on effects of the slope L of nuclear symmetry energy at saturation density and the high-density behavior of nuclear symmetry energy. We find that the variation of either the density slope L or the high-density behavior of nuclear symmetry energy leads to large changes in the binding energy of neutron stars. The difference in predictions using the GR and the scalar-tensor theory appears only for massive neutron stars, and even then is significantly smaller than the difference resulting from variations in the symmetry energy.

  3. The spectral energy distributions of isolated neutron stars in the resonant cyclotron scattering model

    Tong, Hao; Xu, Renxin

    2013-03-01

    The X-ray dim isolated neutron stars (XDINSs) are peculiar pulsar-like objects, characterized by their very well Planck-like spectrum. In studying their spectral energy distributions, the optical/UV excess is a long standing problem. Recently, Kaplan et al. (2011) have measured the optical/UV excess for all seven sources, which is understandable in the resonant cyclotron scattering (RCS) model previously addressed. The RCS model calculations show that the RCS process can account for the observed optical/UV excess for most sources. The flat spectrum of RX J2143.0+0654 may due to contribution from bremsstrahlung emission of the electron system in addition to the RCS process.

  4. Laboratory astrophysics with high energy and high power lasers: from radiative shocks to young star jets

    International Nuclear Information System (INIS)

    Diziere, A.

    2012-01-01

    Laboratory astrophysics are a rapidly developing domain of the High Energy Density Physics. It aims to recreate at smaller scales physical processes that astronomical telescopes have difficulties observing. We shall approach, in this thesis, three major subjects: 1) Jets ejected from young stars, characterized by an important collimation degree and ending with a bow shock; 2) Radiative shocks in which radiation emitted by the shock front itself plays a dominant role in its structure and 3) Accretion shocks in magnetic cataclysmic variables whose important cooling factor allows them to reach stationarity. From the conception to experimental realization, we shall attempt to reproduce in laboratory each of these processes by respecting the scaling laws linking both situations (experimental and astrophysical) established beforehand. The implementation of a large array of visible and X-ray diagnostics will finally allow to completely characterize them and calculate the dimensionless numbers that validate the astrophysical relevance.

    Energy saving is one of the major concerns for low rate personal area networks. This paper models energy consumption for beacon-enabled time-slotted media accessing control cooperated with sleeping scheduling in a star network formulation for IEEE 802.15.4 standard. We investigate two different upstream (data transfer from devices to a network coordinator) strategies: a) tracking strategy: the devices wake up and check status (track the beacon) in each time slot; b) non-tracking strategy: nodes only wake-up upon data arriving and stay awake till data transmitted to the coordinator. We consider the tradeoff between energy cost and average data transmission delay for both strategies. Both scenarios are formulated as optimization problems and the optimal solutions are discussed. Our results show that different data arrival rate and system parameters (such as contention access period interval, upstream speed etc.) result in different strategies in terms of energy optimization with maximum delay constraints. Hence, according to different applications and system settings, different strategies might be chosen by each node to achieve energy optimization for both self-interested view and system view. We give the relation among the tunable parameters by formulas and plots to illustrate which strategy is better under corresponding parameters. There are two main points emphasized in our results with delay constraints: on one hand, when the system setting is fixed by coordinator, nodes in the network can intelligently change their strategies according to corresponding application data arrival rate; on the other hand, when the nodes' applications are known by the coordinator, the coordinator can tune the system parameters to achieve optimal system energy consumption.

    1999-02-01

    The State Energy Data Report (SEDR) provides annual time series estimates of State-level energy consumption by major economic sectors. The estimates are developed in the Combined State Energy Data System (CSEDS), which is maintained and operated by the Energy Information Administration (EIA). The goal in maintaining CSEDS is to create historical time series of energy consumption by State that are defined as consistently as possible over time and across sectors. CSEDS exists for two principal reasons: (1) to provide State energy consumption estimates to Members of Congress, Federal and State agencies, and the general public and (2) to provide the historical series necessary for EIA`s energy models. To the degree possible, energy consumption has been assigned to five sectors: residential, commercial, industrial, transportation, and electric utility sectors. Fuels covered are coal, natural gas, petroleum, nuclear electric power, hydroelectric power, biomass, and other, defined as electric power generated from geothermal, wind, photovoltaic, and solar thermal energy. 322 tabs.

    1996-01-01

    A review of revenues, expenditures and earnings, and 1996 operational highlights of Suncor Energy were presented. Suncor Energy is a leader in oil sands extraction and upgrading technology. In 1996 the company increased its earnings to $187 million, an increase of 24% over the previous year. It achieved record production of 77,600 barrels per day, up from 76,000 barrels per day in 1995. It commissioned a $190 million sulphur dioxide reduction plant which, in concert with other improvements, will cut sulphur dioxide emissions to 25 per cent of 1990 levels. It achieved regulatory approvals on plant expansion and the Steepbank Mine project. It began construction of the bridge across the Athabasca River that will connect Suncor's oil sands plant with the new Steepbank Mine. It added 30 million barrels of oil equivalent of proven new reserves and initiated the first phase of the Burnt Lake heavy oil project. It repositioned and restructured its wholesale and retail marketing businesses in Ontario and Quebec and positioned its Sunoco branded retail business in the top 10 per cent of its markets. Goals for 1997, for each of the company's three business divisions, were also given prominent attention. tabs., figs

    This report takes stock on the nuclear energy situation in Europe. The European Union with more than 40% of the nuclear power capacity in the world, is already confronted with the nuclear energy place and stakes in the future energy policy. The report si presented in two main parts. The first part, ''the assets and the weaknesses of the nuclear energy'', deals with the economical aspects which historically based the choice of the nuclear energy and the induced impacts on the environment. The competitiveness of the nuclear energy but also the wastes management problem are discussed. The second part, ''the diplomatic and juridical framework of the nuclear energy development'', details and presents the limits of the EURATOM treaty. (A.L.B.)

    In the presence of strong magnetic fields, the vacuum becomes a birefringent medium. We show that this QED effect decouples the polarization modes of photons leaving the NS surface. Both the total intensity and the intensity in each of the two modes is preserved along a ray's path through the neutron-star magnetosphere. We analyze the consequences that this effect has on aligning the observed polarization vectors across the image of the stellar surface to generate large net polarizations. Counter to previous predictions, we show that the thermal radiation of NSs should be highly polarized even in the optical. When detected, this polarization will be the first demonstration of vacuum birefringence. It could be used as a tool to prove the high magnetic field nature of AXPs and it could also be used to constrain physical NS parameters, such as $R/M$, to which the net polarization is sensitive.

    There are many areas of desired improvement for the Army Energy and Water Reporting System. The purpose of system is to serve as a data repository for collecting information from energy managers, which is then compiled into an annual energy report. This document summarizes reported shortcomings of the system and provides several alternative approaches for improving application usability and adding functionality. The U.S. Army has been using Army Energy and Water Reporting System (AEWRS) for many years to collect and compile energy data from installations for facilitating compliance with Federal and Department of Defense energy management program reporting requirements. In this analysis, staff from Pacific Northwest National Laboratory found that substantial opportunities exist to expand AEWRS functions to better assist the Army to effectively manage energy programs. Army leadership must decide if it wants to invest in expanding AEWRS capabilities as a web-based, enterprise-wide tool for improving the Army Energy and Water Management Program or simply maintaining a bottom-up reporting tool. This report looks at both improving system functionality from an operational perspective and increasing user-friendliness, but also as a tool for potential improvements to increase program effectiveness. The authors of this report recommend focusing on making the system easier for energy managers to input accurate data as the top priority for improving AEWRS. The next major focus of improvement would be improved reporting. The AEWRS user interface is dated and not user friendly, and a new system is recommended. While there are relatively minor improvements that could be made to the existing system to make it easier to use, significant improvements will be achieved with a user-friendly interface, new architecture, and a design that permits scalability and reliability. An expanded data set would naturally have need of additional requirements gathering and a focus on integrating

    Star fruit (Averrhoa carambola) is commonly consumed as a herbal remedy for various ailments in tropical countries. However, the dangers associated with consumption of star fruit are not commonly known. Although star fruit induced oxalate nephrotoxicity in those with existing renal impairment is well documented, reports on its effect on those with normal renal function are infrequent. We report two unique clinical presentation patterns of star fruit nephrotoxicity following consumption of the fruit as a remedy for diabetes mellitus-the first, in a patient with normal renal function and the second case which we believe is the first reported case of chronic kidney disease (CKD) due to prolonged and excessive consumption of star fruits. The first patient is a 56-year-old female diabetic patient who had normal renal function prior to developing acute kidney injury (AKI) after consuming large amount of star fruit juice at once. The second patient, a 60-year-old male, also diabetic presented with acute on chronic renal failure following ingestion of a significant number of star fruits in a short duration with a background history of regular star fruit consumption over the past 2-3 years. Both had histologically confirmed oxalate induced renal injury. The former had histological features of acute tubulo-interstitial disease whilst the latter had acute-on-chronic interstitial disease; neither had histological evidence of diabetic nephropathy. Both recovered over 2 weeks without the need for haemodialysis. These cases illustrate the importance of obtaining the patient's detailed history with respect to ingestion of herbs, traditional medication and health foods such as star fruits especially in AKI or CKD of unknown cause.

    The U.S. pharmaceutical industry consumes almost $1 billion in energy annually. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pharmaceutical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. pharmaceutical industry is provided along with a description of the major process steps in the pharmaceutical manufacturing process. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in pharmaceutical and related facilities worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers reduce energy consumption in a cost-effective manner while meeting regulatory requirements and maintaining the quality of products manufactured. At individual plants, further research on the economics of the measures?as well as their applicability to different production practices?is needed to assess potential implementation of selected technologies.

  18. Solutions for environmental reporting and energy management

    International Nuclear Information System (INIS)

    Suhonen, T.

    2004-01-01

    Especially two areas of energy applications - environmental reporting and energy management - are emphasized due to the current EU legislation and opening energy markets. Emissions reporting is driven by several EU directives and international agreements, like Emissions Trading Scheme. The directives guide implementation of the emission information management and reporting procedures, but requirements and differences defined by the local authorities are challenging both for the system supplier and for the energy producer. Energy management of industrial energy production (CHP) is an application, which offers real-time tools for forecasting mill's energy need and optimizing the energy balance between a mill's own production, purchases and consumption. This can bring significant reductions in mill energy costs and consumption. For these applications, the exact and well-managed information is needed. Data is retrieved from plant historians and event databases, ERP's and external sources. Calculation applications generate characteristic values (KPI's), which are used for monitoring operation, improving plant availability and boosting performance. Common office tools, like MS Excel, are the most convenient tools for reporting and processing information. Integration tools are needed to combine data from several sources to a single channel, handling messaging between applications and distributing information. (author)

    This year the role of energy technology research and analysis supporting governmental and public interests is again being challenged at high levels of government. This situation is not unlike that of the early 1980s, when the Administration questioned the relevance of a federal commitment to applied energy research, especially for energy efficiency and renewable energy technologies. Then Congress continued to support such activities, deeming them important to the nation`s interest. Today, Congress itself is challenging many facets of the federal role in energy. The Administration is also selectively reducing its support, primarily for the pragmatic objective of reducing federal expenditures, rather than because of principles opposing a public role in energy. this report is divided into three sections: International Energy and the global environment; Energy, economics, markets, and policy; and Buildings and their environment.

    Observations from the Herschel Space Observatory have more than doubled the number of wide debris disks orbiting Sunlike stars to include over 30 systems with R  > 100 AU. Here, we present new Herschel PACS and reanalyzed Spitzer MIPS photometry of five Sunlike stars with wide debris disks, from Kuiper Belt size to R  > 150 AU. The disk surrounding HD 105211 is well resolved, with an angular extent of >14″ along the major axis, and the disks of HD 33636, HD 50554, and HD 52265 are extended beyond the PACS point-spread function size (50% of energy enclosed within radius 4.″23). HD 105211 also has a 24 μ m infrared excess, which was previously overlooked, because of a poorly constrained photospheric model. Archival Spitzer IRS observations indicate that the disks have small grains of minimum radius a min  ∼ 3 μ m, although a min is larger than the radiation-pressure blowout size in all systems. If modeled as single-temperature blackbodies, the disk temperatures would all be <60 K. Our radiative transfer models predict actual disk radii approximately twice the radius of a model blackbody disk. We find that the Herschel photometry traces dust near the source population of planetesimals. The disk luminosities are in the range 2 × 10 −5  ⩽  L / L ⊙  ⩽ 2 × 10 −4 , consistent with collisions in icy planetesimal belts stirred by Pluto-size dwarf planets.

    Analysis of data on collision of protons with targets of He, Be, C, Al, Sn, and Pb continued. A jet signal has been clearly observed from all nuclei. A collaboration has been formed for carrying out an experiment studying the photoproduced jets from nuclei and propagation of quarks and gluons through nuclear matter. The production of lambda hyperons was studied using the primary polarized beam at BNL/AGS at 13.3 and 18.5 GeV/c. The effect of the proton beam polarization on the lambda production, A/sub N/ and spin transfer have been measured. A request was approved for additional polarized proton beam at the AGS to continue measurements of the spin transfer to hyperons. Progress is reported on an initial 200 GeV/c polarized beam-polarized target experiment. A collaborative experiment was approved for the saearch for exotic/hybrid mesons. Investigations in quantum field theories, especially quantum chromodynamics, were contined

    The United Nations Economic Commission for Europe (UNECE) covers a large and diverse region comprising 56 member states. These countries have different energy situations and vary in their potential for and progress in renewable energy and energy efficiency. The present report covers 17 UNECE countries, with the aim of establishing a data baseline and providing a general overview of their renewable energy situations. Over the past decade, the national governments of the selected countries have been working actively to leverage this renewable energy potential. Energy security and access to reliable, affordable, sustainable and modern energy are the key concerns driving renewable energy deployment. These countries require more substantial investment to fully realise its renewable potential and to bring innovative solutions to tackle their energy challenges, such as heating in urban and rural areas. A reliable data baseline is a pre-requisite and an enabler for more investment activity. The UNECE has contributed actively to fulfilling the 17 countries' aspirations in renewable energy by providing them with a platform for collaboration among UNECE member states. In 2014, a UNECE Group of Experts on Renewable Energy was established to step up these efforts. Its mandate is to carry out action-oriented, practical activities to significantly increase the uptake of renewable energy, in line with the United Nations Secretary-General's Sustainable Energy for All (SE4All) initiative. This UNECE Renewable Energy Status Report strives to present analysis of up-to-date data and information on the status of renewable energy and energy efficiency in the selected countries of the UNECE region

    Planetary climate can be affected by the interaction of the host star spectral energy distribution with the wavelength-dependent reflectivity of ice and snow. In this study, we explored this effect with a one-dimensional (1-D), line-by-line, radiative transfer model to calculate broadband planetary albedos as input to a seasonally varying, 1-D energy balance climate model. A three-dimensional (3-D) general circulation model was also used to explore the atmosphere's response to changes in incoming stellar radiation, or instellation, and surface albedo. Using this hierarchy of models, we simulated planets covered by ocean, land, and water-ice of varying grain size, with incident radiation from stars of different spectral types. Terrestrial planets orbiting stars with higher near-UV radiation exhibited a stronger ice-albedo feedback. We found that ice extent was much greater on a planet orbiting an F-dwarf star than on a planet orbiting a G-dwarf star at an equivalent flux distance, and that ice-covered conditions occurred on an F-dwarf planet with only a 2% reduction in instellation relative to the present instellation on Earth, assuming fixed CO(2) (present atmospheric level on Earth). A similar planet orbiting the Sun at an equivalent flux distance required an 8% reduction in instellation, while a planet orbiting an M-dwarf star required an additional 19% reduction in instellation to become ice-covered, equivalent to 73% of the modern solar constant. The reduction in instellation must be larger for planets orbiting cooler stars due in large part to the stronger absorption of longer-wavelength radiation by icy surfaces on these planets in addition to stronger absorption by water vapor and CO(2) in their atmospheres, which provides increased downwelling longwave radiation. Lowering the IR and visible-band surface ice and snow albedos for an M-dwarf planet increased the planet's climate stability against changes in instellation and slowed the descent into global ice

    The State Energy Price and Expenditure Report (SEPER) presents energy price and expenditure estimates for the 50 States, the District of Columbia, and the United States. The estimates are provided by energy source (e.g., petroleum, natural gas, coal, and electricity) and by major consuming or economic sector. This report is an update of the State Energy Price and Expenditure Report 1988 published in September 1990. Changes from the last report are summarized in a section of the documentation. Energy price and expenditure estimates are published for the years 1970, 1975, 1980, and 1985 through 1989. Documentation follows the tables and describes how the price estimates are developed, including sources of data, methods of estimation, and conversion factors applied. Consumption estimates used to calculate expenditures, and the documentation for those estimates, are from the State Energy Data Report, Consumption Estimates, 1960--1989 (SEDR), published in May 1991. Expenditures are calculated by multiplying the price estimates by the consumption estimates, adjusted to remove process fuel and intermediate product consumption. All expenditures are consumer expenditures, that is, they represent estimates of money directly spent by consumers to purchase energy, generally including taxes. 11 figs., 43 tabs

    The State Energy Price and Expenditure Report (SEPER) presents energy price and expenditure estimates for the 50 States, the District of Columbia, and the United States. The estimates are provided by energy source (e.g., petroleum, natural gas, coal, and electricity) and by major consuming or economic sector. This report is an update of the State Energy Price and Expenditure Report 1988 published in September 1990. Changes from the last report are summarized in a section of the documentation. Energy price and expenditure estimates are published for the years 1970, 1975, 1980, and 1985 through 1989. Documentation follows the tables and describes how the price estimates are developed, including sources of data, methods of estimation, and conversion factors applied. Consumption estimates used to calculate expenditures, and the documentation for those estimates, are from the State Energy Data Report, Consumption Estimates, 1960--1989 (SEDR), published in May 1991. Expenditures are calculated by multiplying the price estimates by the consumption estimates, adjusted to remove process fuel and intermediate product consumption. All expenditures are consumer expenditures, that is, they represent estimates of money directly spent by consumers to purchase energy, generally including taxes. 11 figs., 43 tabs.

    The report consists of two chapters. Chapter 1 addresses the present status and future trends in the field of atomic energy. The present conditions of atomic energy development and social background behind them are described first. Features of atomic energy is discussed in relation to its technique-intensive aspect, stability of supply, stability of price, environmental load, and handling of radioactive materials. The relations of these features with energy policies are then discussed, focusing on basic political principles, optimum combination of various energy sources, and the role to be played by atomic energy. This chapter then deals with future trends in atomic energy development efforts and major problems remaining to be solved. Future supply and demand of energy and electric power are discussed. Problems related with atomic energy development are described focusing on some severe conditions depressing the development activities, and measures to be taken immediately. Chapter 2 describes important issues and measures to be taken in the future towards atomic energy development. Discussion is made on safety measures, back-end measures, promotion of location activities, and publicity. (N.K.)

    The eigenfrequencies of the axial w-modes of oscillating neutron stars are studied using the continued fraction method with an equation of state (EOS) partially constrained by the recent terrestrial nuclear laboratory data. It is shown that the density dependence of the nuclear symmetry energy E sym (ρ) affects significantly both the frequencies and the damping times of these modes. Besides confirming the previously found universal behavior of the mass-scaled eigenfrequencies as functions of the compactness of neutron stars, we explored several alternative universal scaling functions. Moreover, the w II -mode is found to exist only for neutron stars having a compactness of M/R≥0.1078 independent of the EOS used.

  19. The embedded young stars in the Taurus-Auriga molecular cloud. I - Models for spectral energy distributions

    Kenyon, Scott J.; Calvet, Nuria; Hartmann, Lee

    1993-01-01

    We describe radiative transfer calculations of infalling, dusty envelopes surrounding pre-main-sequence stars and use these models to derive physical properties for a sample of 21 heavily reddened young stars in the Taurus-Auriga molecular cloud. The density distributions needed to match the FIR peaks in the spectral energy distributions of these embedded sources suggest mass infall rates similar to those predicted for simple thermally supported clouds with temperatures about 10 K. Unless the dust opacities are badly in error, our models require substantial departures from spherical symmetry in the envelopes of all sources. These flattened envelopes may be produced by a combination of rotation and cavities excavated by bipolar flows. The rotating infall models of Terebey et al. (1984) models indicate a centrifugal radius of about 70 AU for many objects if rotation is the only important physical effect, and this radius is reasonably consistent with typical estimates for the sizes of circumstellar disks around T Tauri stars.

    In Canada, the dairy sector consumes significant amounts of energy and is looking for new ways of saving energy. The aim of this study, performed by the Competitive Analysis Centre Inc., was to find novel energy savings ideas for fluid milk plants. For this purpose, the energy consumption of 17 fluid milk plants, which accounts for over 50% of total Canadian output, was analyzed; first, at the plant level, and then by 8 categories at the sub-plant level in order to develop benchmarks that could be applied at both these levels. The paper provides background information on Canada's fluid milk sector and outlines the methodology used to develop and apply energy efficiency measures in the sector; the study findings are also presented. This report found that the energy consumption of the Canadian fluid milk sector could be lowered by applying the energy saving proposals developed herein.

    2003-09-01

    Annually, breweries in the United States spend over $200 million on energy. Energy consumption is equal to 38 percent of the production costs of beer, making energy efficiency improvement an important way to reduce costs, especially in times of high energy price volatility. After a summary of the beer making process and energy use, we examine energy efficiency opportunities available for breweries. We provide specific primary energy savings for each energy efficiency measure based on case studies that have implemented the measures, as well as references to technical literature. If available, we have also listed typical payback periods. Our findings suggest that given available technology, there are still opportunities to reduce energy consumption cost-effectively in the brewing industry. Brewers value highly the quality, taste and drinkability of their beer. Brewing companies have and are expected to continue to spend capital on cost-effective energy conservation measures that meet these quality, taste and drinkability requirements. For individual plants, further research on the economics of the measures, as well as their applicability to different brewing practices, is needed to assess implementation of selected technologies.

    2007-11-15

    Between 1999 and 2006, home energy audits were conducted in 770 scattered houses belonging to the Toronto Community Housing Corporation (TCHC). Over the course of the project, 126 houses were retrofitted with energy saving measures based on calculations of the most cost-effective measures. This report outlined the work that was conducted by the contractor, GreenSaver over the course of the project. The report discussed the project players and project execution. It included a profile of audited houses; auditing procedure; house reports; retrofit work; contractor arranging service; and post-retrofit inspections. Comments on retrofit work not carried out were also provided. The report also discussed the results of the project, including energy savings and emission reductions and participant feedback. A summary of the energy efficiency retrofit survey was also presented along with lessons learned. These included the availability of a contingency fund; the importance of tenant involvement; and making arrangements for other repair work. It was concluded that the amount of expected energy savings on space heating bills varied from house to house, and fell between 15 and 74 per cent. The report recommended that tenants and staff in the social housing sector could benefit from a greater awareness of energy issues and its more efficient use, allowing even greater and longer lasting benefits from a project like this. 8 tabs.

    International Nuclear Information System (INIS)

    1994-01-01

    The International Energy Agency is interested by the energy policy of its 23 members countries. This book sums up the evolution of energy policy in 1991 and 1992, sticking particularly to energy proposal and demand, to energy efficiency, to interaction between energy and environment, to the energy technology and to research and development activities. The 23 countries are examined regularly. The elaborate examinations refer to the energy policy of each member country to dictate the common orientation of their policy. Ministers meetings of IEA take place regularly. The latest took place in PARIS on the fourth of June 1993 where the ministers confirmed that there were essential elements of the energy policy and that they recommended to all countries to take that in account in the formulation of their strategies. Beyond the examinations by country, this book contains a whole report which throws into relief the main new acts which were happened in the IEA members countries and a glimpse on the evolution of the energy situation in the no members countries. It gives specific data and informations on the governmental budgets allocated to research and development energy activities. 6 annexes, 12 graphs., 5 tabs

    1998-03-01

    This report describes the work that Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory has been doing most recently. One of our proudest accomplishments is the publication of Scenarios of U.S. Carbon Reductions, an analysis of the potential of energy technologies to reduce carbon emissions in the U.S. This analysis played a key role in shaping the U.S. position on climate change in the Kyoto Protocol negotiations. Our participation in the fundamental characterization of the climate change issue by the IPCC is described. We are also especially proud of our study of ''leaking electricity,'' which is stimulating an international campaign for a one-watt ceiling for standby electricity losses from appliances. This ceiling has the potential to save two-thirds of the 5% of U.S. residential electricity currently expended on standby losses. The 54 vignettes contained in the following pages summarize results of research. activities ranging in scale from calculating the efficacy of individual lamp ballasts to estimating the cost-effectiveness of the national ENERGY STAR{reg_sign} labeling program, and ranging in location from a scoping study of energy-efficiency market transformation in California to development of an energy-efficiency project in the auto parts industry in Shandong Province, China. These are the intellectual endeavors of a talented team of researchers dedicated to public service.

    Color temperatures have been estimated by comparing ultraviolet observations of HgMn and magnetic Ap stars with those of normal stars. Ultraviolet data from the OAO-2, ANS, TD-1, and IUE satellites generally give similar results. The values for the normal stars were derived from comparison of fluxes predicted by solar-composition fully line-blanketed model atmospheres with optical region spectrophotometry. The ultraviolet temperatures of the HgMn stars cover a narrower temperature range than do their optical region values. Magnetic Ap stars with similar optical region temperatures can show substantial differences in their ultraviolet color temperatures. This may result from magnetic field configuration and abundance differences. 27 references

    Dependences between Δmsub(u) and msub(u) are given for the Orion, NGC 7000, Pleiades and Praesepe aggregations. Maximum absolute values of flares have been calculated for stars with different luminosities. It has been shown that the values of flares can be limited by a straight line which gives the representation on the distribution of maximum values of amplitudes for the stars with different luminosities in an aggregation. Presented are k and m 0 parameters characterizing the lines fot the Orion, NGC 7000, Pleiades and Praesepe aggregation and their age T dependence. From the dependence between k (angular coefficient of straight lines) and lgT for the aggregation with known T the age of those aggregation involving a great amount of flaring stars can be found. The age of flaring stars in the neighbourhood of the Sun has been determined. The age of UV Ceti has been shown by an order to exceed that of the rest stars

The next part addresses the relationship between electricity grids and territories (solidarity between electricity grids as the basis of the Europe of energy, evolution of French grids to face new needs and to take regional and local dimensions into account). Another part addresses gas infrastructures which are considered as the cornerstone of a good operation for the French market and for the integration of the European energy market (gas world market in 2012, definition of a target model for the gas market by European regulators, evolution of the French market in compliance with the European target model, new tariffs for the use of natural gas transport networks). The report then addresses the development of renewable energies: actions of CRE (bidding, opinion of tariffs), influence of renewable energy development on electricity prices on gross markets, needed evolution of electricity grids. A last part addresses the issues of energy cost, demand management, and struggle against energy poverty

  18. Land use and energy utilization. Final report

    1977-06-01

    Land use plays an important role in structuring the basic patterns in which energy is consumed in many areas of the U.S. Thus, in considering policies at a national or local level, which are aimed at either utilizing energy supplies in a more efficient manner, or in establishing the compatibility of new energy supply, conversion, and end use technologies with our existing social patterns of energy use, it is important to understand the interdependencies between land use and energy. The Land Use-Energy Utilization Project initiated in July 1974 was designed to explore the quantitative relationships between alternative regional land-use patterns and their resultant energy and fuel demands and the impacts of these demands on the regional and national energy supply-distribution systems. The project studies and analyses described briefly in this report provide a framework for delineating the energy system impacts of current and projected regional land-use development; a base of information dealing with the energy intensiveness of assorted land-use activities; models that enable Federal and regional planners to estimate the ranges of potential energy savings that could be derived from employing alternative land-use activity configurations; and a user manual for allowing local land use planners to carry out their own land use-energy impact evaluations. Much remains to be done to elucidate the complicated interdependencies between land use and energy utilization: what is accomplished here is an initial structuring of the problem. On the other hand, the recent increase in interest in establishing new ways for the U.S. to achieve energy conservation suggests that actions will be taken in the near future to tie land-use development to national and local targets for conservation.

    Dust grains control the chemistry and cooling, and thus the gravitational collapse of interstellar clouds. Energetic particles, shocks and ionizing radiation can have a profound influence on the structure, lifetime and chemical reactivity of the dust, and therefore on the star formation efficiency. This would be especially important in forming galaxies, which exhibit powerful starburst (supernovae) and AGN (active galactic nucleus) activity. How dust properties are affected in such environments may be crucial for a proper understanding of galaxy formation and evolution. The authors present the results of experiments at LLNL which show that irradiation of the interstellar medium (ISM) dust analog forsterite (Mg 2 SiO 4 ) with swift heavy ions (10 MeV Xe) and a large electronic energy deposition amorphizes its crystalline structure, without changing its chemical composition. From the data they predict that silicate grains in the ISM, even in dense and cold giant molecular clouds, can be amorphized by heavy cosmic rays (CR's). This might provide an explanation for the observed absence of crystalline dust in the ISM clouds of the Milky Way galaxy. This processing of dust by CR's would be even more important in forming galaxies and galaxies with active black holes

    This Summer's edition of the Grenoble Ecole de Management (GEM) Energy Market Barometer documents the French energy experts' expectations of the impact of the Ukraine crisis on energy supply, the focus of energy policy in France, the economic implications of the energy transition, and the development of energy prices. The findings on the Ukraine crisis are also compared to a parallel survey in Germany, which was carried out by the Center for European Economic Research (ZEW). Key findings: - Half the French experts believe that the Ukraine crisis has worsened the security of natural gas supply in France; - Appropriate responses to the Ukraine crisis include strengthening the EU energy market integration, and investing in pipelines and in liquefied natural gas infrastructure; - The high perceived emphasis on energy efficiency in the current French energy policy is justified, but the focus on affordability for households and security of supply appears somewhat overrated; - The French energy transition is expected to hurt utilities, but to benefit technology providers and the economy as a whole; - Most experts believe the prices for electricity, gas, oil, and coal will remain relatively stable over the next 6 months, but they will increase over the next 5 years (except coal); - Expected prices of CO_2 certificates have slightly increased since the previous barometer report, in particular for the medium term

    This Risoe Energy Report, the seventh of a series that began in 2002, takes as its point of reference the recommendations of the Intergovernmental Panel on Climate Change (IPCC) in 2007. The IPCC states that if anticipated climate change is to remain in the order of 2 to 3 degrees centigrades over the next century, the world's CO{sub 2} emissions would have to peak within the next 10-15 years and ultimately be reduced to approximately 50% of their present level by the middle of the century. The IPCC states further that this would be possible, provided that serious action is taken now. The different regions and countries of the world are in various states of development, and hence have different starting points for contributing to these reductions in CO{sub 2} emissions. This report presents state-of-the-art and development perspectives for energy supply technologies, new energy systems, end-use energy efficiency improvements and new policy measures. It also includes estimates of the CO{sub 2} reduction potentials for different technologies. The technologies are characterized with regard to their ability to contribute either to ensuring a peak in CO{sub 2} emissions within 10-15 years, or to long-term CO{sub 2} reductions. The report outlines the current and likely future composition of energy systems in Denmark, and examines three groups of countries: i) Europe and the other OECD member nations; ii) large and rapidly growing developing economies, notably India and China; iii) typical least developed countries, such as many African nations. The report emphasises how future energy developments and systems might be composed in these three country groupings, and to what extent the different technologies might contribute. The report addresses the need for research and demonstration together with market incentives, and policy measures with focus on initiatives that can promote the development towards CO{sub 2} reductions. Specifically, the report identifies system

  4. Restructuring the Energy System. Report of the Energy Commission

    International Nuclear Information System (INIS)

    1995-01-01

    The commission was instructed to examine the current energy policy programs for restructuring and developing the energy system (i.e. phasing out nuclear power and moving to renewable sources) and to analyze the needs for changes; to propose measures for ensuring an efficient electricity supply under the new conditions of a liberalized electricity market; and to present proposals for a schedule for reorganizing the energy system. The report gives a full picture of the Swedish energy system including supply, consumption, prices, environmental impacts, R and D, and international aspects. The commission concludes that one nuclear power plant can be closed during the 1990's without upsetting the power balances. Phasing out all nuclear plants by year 2010 will create problems with the price levels of electricity supply, and will conflict with the CO 2 reduction objective. The proposals for economic control measures for performing the restructuring include: An environmental bonus (or investment support) for environmentally sound electricity production financed by an electricity tax, a tax on nuclear power increasing with the age of the reactors, a reorganization fund to finance new and environmentally acceptable electricity production. Also, energy research should be allotted greater resources, in particular for new technology for electricity production. The commission points towards the possibilities for reducing energy consumption, and especially electricity consumption. Space heating should gradually move away from electric heating. Examples are given on measures for improving energy efficiency and problems with financing such measures should be studied

    1976-01-01

    The findings of a Commission set up in 1975 to report to Belgium's Minister of Economic Affairs on the various aspects of the question of nuclear energy are discussed. The Commission is basically in favour of the increased use of nuclear energy for the production of electricity, but emphasises that the main purpose of its Report is to furnish reasoned judgements to serve as the basis for informed debate. It concludes that the matter is essentially political. Economic, technical, public health and environmental aspects are considered. The present nuclear power programme is briefly reviewed, including reactors planned for up to 1982. The main conclusions of the Report are summarised, including economic and financial considerations. The possibilities of alternative sources of energy are considered, and it is concluded that only coal, oil and natural gas could be important for Belgium in the short or medium term. A policy of diversification should be favoured. (U.K.)

    Knowledge about the innovation systems with respect to new energy solutions and technologies is of central importance for understanding the dynamics of change in the energy sector and assessment of opportunities for moving towards more climate-friendly and sustainable energy systems and for socio-economic development in the field, creation of new businesses, work places, etc.. This is the topic that in general is addressed in the research activities of the ''EIS - Strategic research alliance for Energy Innovation Systems and their dynamics - Denmark in global competition''. As part of this, the present report gives an overview of the available indicators of energy innovation systems and points out some of the limitations and potentials there currently are in this connection. Focus is on Denmark. Figures for other countries, primarily Nordic or European, are in some cases showed as well, offering a comparative perspective. (Author)

    Glendenning, N.K.

    1989-11-01

    We investigate the implications of rapid rotation corresponding to the frequency of the new pulsar reported in the supernovae remnant SN1987A. It places very stringent conditions on the equation of state if the star is assumed to be bound by gravity alone. We find that the central energy density of the star must be greater than 13 times that of nuclear density to be stable against the most optimistic estimate of general relativistic instabilities. This is too high for the matter to consist of individual hadrons. We conclude that it is implausible that the newly discovered pulsar, if its half-millisecond signals are attributable to rotation, is a neutron star. We show that it can be a strange quark star, and that the entire family of strange stars can sustain high rotation if strange matter is stable at an energy density exceeding about 5.4 times that of nuclear matter. We discuss the conversion of a neutron star to strange star, the possible existence of a crust of heavy ions held in suspension by centrifugal and electric forces, the cooling and other features. 34 refs., 10 figs., 1 tab

    Planets in close-in orbit interact with the magnetized wind of their hosting star. This magnetic interaction was proposed to be a source for enhanced emissions in the chromosphere of the star, and to participate in setting the migration time-scale of the close-in planet. The efficiency of the magnetic interaction is know to depend on the magnetic properties of the host star, of the planet, and on the magnetic topology of the interaction. We use a global, three-dimensional numerical model of c...

    1981-01-01

    The least massive, but possibly most numerous, stars in a galaxy are the dwarf M stars. It has been observed that some of these dwarfs are characterized by a short increase in brightness. These stars are called flare stars. These flare stars release a lot of energy in a short amount of time. The process producing the eruption must be energetic. The increase in light intensity can be explained by a small area rising to a much higher temperature. Solar flares are looked at to help understand the phenomenon of stellar flares. Dwarfs that flare are observed to have strong magnetic fields. Those dwarf without the strong magnetic field do not seem to flare. It is believed that these regions of strong magnetic fields are associated with star spots. Theories on the energy that power the flares are given. Astrophysicists theorize that the driving force of a stellar flare is the detachment and collapse of a loop of magnetic flux. The mass loss due to stellar flares is discussed. It is believed that stellar flares are a significant contributor to the mass of interstellar medium in the Milky Way

    The frequencies and damping times of the axial w-mode oscillations of neutron stars are investigated using a nuclear equation of state (EOS) partially constrained by the available terrestrial laboratory data. It is found that the nuclear symmetry energy E sym (ρ), especially its high density behavior, plays an important role in determining both the eigen-frequencies and the damping times of these oscillations.

    We present the first rest-frame UV population study of 17 heavily reddened, high-luminosity [E(B - V)QSO ≳ 0.5; Lbol > 1046 erg s-1] broad-line quasars at 1.5 VISTA Hemisphere Survey and UKIDSS Large Area Survey data, from which the reddened quasars were initially identified. We demonstrate that the significant dust reddening towards the quasar in our sample allows host galaxy emission to be detected at the rest-frame UV wavelengths probed by the DES photometry. By exploiting this reddening effect, we disentangle the quasar emission from that of the host galaxy via spectral energy distribution fitting. We find evidence for a relatively unobscured, star-forming host galaxy in at least 10 quasars, with a further three quasars exhibiting emission consistent with either star formation or scattered light. From the rest-frame UV emission, we derive instantaneous, dust-corrected star formation rates (SFRs) in the range 25 < SFRUV < 365 M⊙ yr-1, with an average SFRUV = 130 ± 95 M⊙ yr-1. We find a broad correlation between SFRUV and the bolometric quasar luminosity. Overall, our results show evidence for coeval star formation and black hole accretion occurring in luminous, reddened quasars at the peak epoch of galaxy formation.

  1. THE COOLING OF THE CASSIOPEIA A NEUTRON STAR AS A PROBE OF THE NUCLEAR SYMMETRY ENERGY AND NUCLEAR PASTA

    X-ray observations of the neutron star (NS) in the Cas A supernova remnant over the past decade suggest the star is undergoing a rapid drop in surface temperature of ≈2%-5.5%. One explanation suggests the rapid cooling is triggered by the onset of neutron superfluidity in the core of the star, causing enhanced neutrino emission from neutron Cooper pair breaking and formation (PBF). Using consistent NS crust and core equations of state (EOSs) and compositions, we explore the sensitivity of this interpretation to the density dependence of the symmetry energy L of the EOS used, and to the presence of enhanced neutrino cooling in the bubble phases of crustal ''nuclear pasta''. Modeling cooling over a conservative range of NS masses and envelope compositions, we find L ≲ 70 MeV, competitive with terrestrial experimental constraints and other astrophysical observations. For masses near the most likely mass of M ≳ 1.65 M {sub ☉}, the constraint becomes more restrictive 35 ≲ L ≲ 55 MeV. The inclusion of the bubble cooling processes decreases the cooling rate of the star during the PBF phase, matching the observed rate only when L ≲ 45 MeV, taking all masses into consideration, corresponding to NS radii ≲ 11 km.

    The report is the Danish contribution to the project `Utilities and Energy Efficiency` produced for the European Commission by IET, Nikkel straat 15, 4823 AE Breda, The Netherlands. Information is given under the headings of existing situation and desired situation. Recommendations are also given under the headings of legislation concerning the objectives of the utilities, of government programs and targets, of organizational structure, required market dependence and internal objectives of the utilities, for regulation and standardization, and of tariff structure. Flow diagrams are presented for the Danish energy system 1990, 1993. The 1993 follow up of the energy plan `Energy 2000` points out that the goals set up at that time, first and foremost the 20% reduction in CO{sub 2} emissions in 2005 compared to the 1988 level, will not be reached without changes in policy, such as an increase in the use of renewable energy, more transparent and consistent tariff systems as a greater incentive for energy conservation, regulations on thermal insulation of houses, increase in public information activities,a new subsidy scheme to stimulate improvements of energy efficiency in buildings and regulations on energy supply to large buildings.

    2015-10-01

    For many years tourniquets were perceived as dangerous due to the belief that they led to loss of limb because of ischemia. Their use in civilian and military environments was discouraged. Emergency medical responders were not taught about tourniquets and commercial tourniquets were not available. However, research by the United States military during the wars in Iraq and Afghanistan has demonstrated that tourniquets are safe life-saving devices. As a consequence, they have been widely deployed in combat situations and there are now calls for the use of tourniquets in the civilian prehospital setting. This article presents a report of the successful application of a tourniquet by the LIFE STAR crew to control bleeding that local emergency medical services (EMS) personnel could not control with direct pressure. Tourniquets should be readily available in public places and carried by all EMS.

    2016-03-01

    Compact objects such as neutron stars are ideal astrophysical laboratories to test our understanding of the fundamental interactions in the regime of supranuclear densities, unachievable by terrestrial experiments. Despite recent progress, the description of matter (i.e., the equation of state) at such densities is still debatable. This translates into uncertainties in the bulk properties of neutron stars, masses and radii for instance. Here we will consider low-mass neutron stars. Such stars are expected to carry important information on nuclear matter near the nuclear saturation point. It has recently been shown that the masses and surface redshifts of low-mass neutron stars smoothly depend on simple functions of the central density and of a characteristic parameter η associated with the choice of equation of state. Here we extend these results to slowly-rotating and tidally deformed stars and obtain empirical relations for various quantities, such as the moment of inertia, quadrupole moment and ellipticity, tidal and rotational Love numbers, and rotational apsidal constants. We discuss how these relations might be used to constrain the equation of state by future observations in the electromagnetic and gravitational-wave spectra.

  5. ELECTROMAGNETIC EXTRACTION OF ENERGY FROM BLACK-HOLE–NEUTRON-STAR BINARIES

    International Nuclear Information System (INIS)

    McWilliams, Sean T.; Levin, Janna

    2011-01-01

    The coalescence of black-hole-neutron-star binaries is expected to be a principal source of gravitational waves for the next generation of detectors, Advanced LIGO and Advanced Virgo. For black hole masses not much larger than the neutron star mass, the tidal disruption of the neutron star by the black hole provides one avenue for generating an electromagnetic counterpart. However, in this work, we demonstrate that, for all black-hole-neutron-star binaries observable by Advanced LIGO/Virgo, the interaction of the black hole with the magnetic field of the neutron star will generate copious luminosity, comparable to supernovae and active galactic nuclei. This novel effect may have already been observed as a new class of very short gamma-ray bursts by the Swift Gamma-Ray Burst Telescope. These events may be observable to cosmological distances, so that any black-hole-neutron-star coalescence detectable with gravitational waves by Advanced LIGO/Virgo could also be detectable electromagnetically.

    The Program became deeply involved in establishing 4 Washington, D.C., project office diving the last few months of fiscal year 1942. This project office, which reports to the Energy & Environment Division, will receive the majority of its support from the Energy Analysis Program. We anticipate having two staff scientists and support personnel in offices within a few blocks of DOE. Our expectation is that this office will carry out a series of projects that are better managed closer to DOE. We also anticipate that our representation in Washington will improve and we hope to expand the Program, its activities, and impact, in police-relevant analyses. In spite of the growth that we have achieved, the Program continues to emphasize (1) energy efficiency of buildings, (2) appliance energy efficiency standards, (3) energy demand forecasting, (4) utility policy studies, especially integrated resource planning issues, and (5) international energy studies, with considerate emphasis on developing countries and economies in transition. These continuing interests are reflected in the articles that appear in this report.

    Here we present the main elements of the annual report on energy efficiency 2015. The results indicate that, thanks to national policies for energy efficiency, Italy saved over 7.5 million tons of oil equivalent per year in the period 2005-2013. Compared to the National Plan for Energy Efficiency 2014, the report shows that the 2020 objectives have already been achieved for more than 20%, with residential (35.7% of the target) and industry (26.6%) among the sectors that contributed most to this result. Substantial savings could result from the agribusiness sector through the dissemination of efficient technologies in the logistics and large retail chains. A key role lies with the banks: 86% of banks has developed products dedicated to efficiency, necessitating guidelines for replicability of projects, and audit and rating to assess their quality [it

    2003-02-01

    Nova Scotia's energy strategy addresses all aspects of energy production and use, from offshore oil and gas to electricity and coal, to climate change and renewable resources. It also encompasses energy conservation and efficiency. This progress report highlights the efforts that the province has made to promote exploration, improve efficiency of regulations and approval processes and promote the oil and natural gas sector. Efforts have also been made to support local businesses, address climate change issues and protect the environment. The strategy demonstrates how new energy resources can be used to build a more prosperous and self-reliant province. The progress report focuses on the following 3 themes: powering the economy; improving the environment; and, securing Nova Scotia's future. The report emphasizes that the growing oil and gas industry brings many opportunities for new jobs and a stronger economy. In the next 12 to 18 months, about 8 to 10 offshore exploration wells will be drilled, which is more than in the last decade. Funding will be provided to extend pipeline systems beyond franchise areas approved by the Nova Scotia Utility and Review Board. In May 2002, the Electricity Marketplace Governance Committee was formed to make recommendations on how competition can be introduced into the province's electricity market. The Department of Energy has been working to implement initiatives to increase the use of renewable energy sources such as solar and wind power. In October 2002, new wind turbines began producing electricity in 3 communities on Cape Breton Island. A key priority is to respond to climate change and reduce greenhouse gas emissions as well as emissions of mercury, sulphur, nitrogen, and ozone. The energy strategy also identifies the need to provide competitive taxation regimes.

    The Southern African Development Community (SADC) is one of the oldest regional economic communities on the African continent. It has developed into a progressive regional institution providing guidance to 15 member states, covering a wide range of economic, social and geographic characteristics. SADC is now becoming a key player in the international trend towards development of renewable energy resources as well as energy efficiency. The SADC Renewable Energy and Energy Efficiency Status Report supports SADC's efforts to increase the deployment of renewable energy and energy efficiency in Southern Africa by providing a comprehensive regional review of renewable energy and energy efficiency developments, evolving policy landscapes, market trends and related activities, achievements in renewable energy on- and off-grid, and opportunities for the financing of these activities. With an expanding population of 298 million, SADC accounted for approximately 32% of sub-Saharan Africa's total population of 926 million in 2014. Three countries - the Democratic Republic of Congo (DRC), South Africa and Tanzania - together account for more than 60% of the region's population. Country GDPs vary widely, from USD 1.3 billion (Seychelles) to USD 349 billion (South Africa), as does GDP per capita, ranging from USD 342 (Malawi) to USD 15,347 (Seychelles). There are also differences in levels of socio-economic development, as measured by the United Nations Human Development Index (HDI): from a low of 0.338 (the DRC) to a high of 0.771 (Mauritius), reflecting the huge disparities in income, education, social services and infrastructure among these countries. In the energy sector, SADC has focused on two areas: improving access to modern energy services for off-grid populations, and increasing the security and stability of energy supplies generally. To achieve its goals, SADC has developed a series of guiding documents, including the SADC Energy Protocol, the Regional Indicative

    Energy Impact Illinois (EI2) is an alliance of government organizations, nonprofits, and regional utility companies led by the Chicago Metropolitan Agency for Planning (CMAP) that is dedicated to helping communities in the Chicago metropolitan area become more energy efficient. Originally organized as the Chicago Region Retrofit Ramp-Up (CR3), EI2 became part of the nationwide Better Buildings Neighborhood Program (BBNP) in May 2010 after receiving a $25 million award from the U.S. Department of Energy (DOE) authorized through the American Recovery and Reinvestment Act of 2009 (ARRA). The program’s primary goal was to fund initiatives that mitigate barriers to energy efficiency retrofitting activities across residential, multifamily, and commercial building sectors in the seven-county CMAP region and to help to build a sustainable energy efficiency marketplace. The EI2 Final Technical Report provides a detailed review of the strategies, implementation methods, challenges, lessons learned, and final results of the EI2 program during the initial grant period from 2010-2013. During the program period, EI2 successfully increased direct retrofit activity in the region and was able to make a broader impact on the energy efficiency market in the Chicago region. As the period of performance for the initial grant comes to an end, EI2’s legacy raises the bar for the region in terms of helping homeowners and building owners to take action on the continually complex issue of energy efficiency.

  2. Energy efficiency improvement and cost saving opportunities for the Corn Wet Milling Industry: An ENERGY STAR Guide for Energy and Plant Managers

    2003-07-01

    Corn wet milling is the most energy intensive industry within the food and kindred products group (SIC 20), using 15 percent of the energy in the entire food industry. After corn, energy is the second largest operating cost for corn wet millers in the United States. A typical corn wet milling plant in the United States spends approximately $20 to $30 million per year on energy, making energy efficiency improvement an important way to reduce costs and increase predictable earnings, especially in times of high energy-price volatility. This report shows energy efficiency opportunities available for wet corn millers. It begins with descriptions of the trends, structure and production of the corn wet milling industry and the energy used in the milling and refining process. Specific primary energy savings for each energy efficiency measure based on case studies of plants and references to technical literature are provided. If available, typical payback periods are also listed. The report draws upon the experiences of corn, wheat and other starch processing plants worldwide for energy efficiency measures. The findings suggest that given available resources and technology, there are opportunities to reduce energy consumption cost-effectively in the corn wet milling industry while maintaining the quality of the products manufactured. Further research on the economics of the measures, as well as the applicability of these to different wet milling practices, is needed to assess the feasibility of implementation of selected technologies at individual plants.

  3. Simulating the formation and evolution of galaxies: multi-phase description of the interstellar medium, star formation, and energy feedback

    Merlin, E.; Chiosi, C.

    2007-10-01

    Context: Modelling the gaseous component of the interstellar medium (ISM) by Smoothed Particles Hydrodynamics in N-Body simulations (NB-TSPH) is still very crude when compared to the complex real situation. In the real ISM, many different and almost physically decoupled components (phases) coexist for long periods of time, and since they spread over wide ranges of density and temperature, they cannot be correctly represented by a unique continuous fluid. This would influence star formation which is thought to take place in clumps of cold, dense, molecular clouds, embedded in a warmer, neutral medium, that are almost freely moving throughout the tenuous hot ISM. Therefore, assuming that star formation is simply related to the gas content without specifying the component in which this is both observed and expected to occur may not be physically sound. Aims: We consider a multi-phase representation of the ISM in NB-TSPH simulations of galaxy formation and evolution with particular attention to the case of early-type galaxies. Methods: Cold gas clouds are described by the so-called sticky particles algorithm. They can freely move throughout the hot ISM medium; stars form within these clouds and the mass exchange among the three baryonic phases (hot gas, cold clouds, stars) is governed by radiative and Compton cooling and energy feedback by supernova (SN) explosions, stellar winds, and UV radiation. We also consider thermal conduction, cloud-cloud collisions, and chemical enrichment. Results: Our model agrees with and improves upon previous studies on the same subject. The results for the star formation rate agree with recent observational data on early-type galaxies. Conclusions: These models lend further support to the revised monolithic scheme of galaxy formation, which has recently been strengthened by high redshift data leading to the so-called downsizing and top-down scenarios.

    A survey was conducted to gather information on energy use and the factors affecting energy use in households residing in houses and residential buildings with fewer than 5 storeys. Dwelling characteristics, usage of appliances, and energy efficiency and consumption data were collected. An overview of the main findings were presented in this summary and included details of thermal envelopes; residential heating, air-conditioning and ventilation; household appliances; hot water; lighting; and Energy Star systems and appliances. The survey covered over 11 million households in all 10 Canadian provinces. Data were collected through computer-assisted personal interviews with owners, renters, landlords and property managers. It was observed that the average heated area of a Canadian dwelling was 1321 square feet, and that dwellings constructed after 1979 were larger and more energy efficient than previous dwellings. The majority of households located west of Quebec used natural gas, whereas the majority of Quebec households used electricity. Households in the Atlantic region used both electricity and oil. Penetration rates for high efficiency furnaces using natural gas, propane or oil furnaces was 62 per cent among dwellings built between 1990-2003. It was noted that more basements, attics, crawlspaces and garages are now being insulated. An increasing number of households use both a main and a secondary refrigerator. Nearly 25 per cent of households used 3 or more televisions. The use of central and window/room air-conditioners has increased, with Ontario households accounting for more than 60 per cent of all air-conditioning systems. Nearly 25 per cent of light bulbs were energy-efficient bulbs. It was also observed that Energy Star products have had a high penetration since the inception of the Energy Star initiative. However, a significant number of households were not aware if their products were Energy Star qualified. tabs., figs.

    This is a NEDO (New Energy and Industrial Technology Development Organization) report of January 1990, based on a Koleda Childress and Company of EPA report. Comments are made on the development status of fossil and synthetic fuels in the U.S. In the Department of Energy budget, emphasis is placed on environments, science, and national security, and the budget for fiscal 1991 is 17.5 times 1 billion dollars which is 6% higher than the ordinary level. In Round 3 of the Clean Coal Technology Program, the Department of Energy has selected 13 programs for negotiations. NEDO has completed its national energy strategy draft. What attracts attention is the synthetic fuel as an alternative fuel. It is expected that coal, oil shale, and tar sand will be the raw materials. Combined cycle power generation is recommended for coal gasification. As for indirect coal liquefaction, technology of conversion to syngas will be accelerated. In the future, the direct coal liquefaction product will compete with oil in terms of cost. Oil shale retorting and tar sand processing are taken up. Recent global warming measures and energy forecast into 2010 are shown. (NEDO)

    The potential for electric energy from geothermal resources in California is currently estimated to be equivalent to the output from 14 to 21 large (1000 MW) central station power plants. In addition, since over 30 California cities are located near potential geothermal resources, the non-electric applications of geothermal heat (industrial, agriculture, space heating, etc.) could be enormous. Therefore, the full-scale utilization of geothermal resources would have a major impact upon the energy picture of the state. This report presents a summary of the existing status of geothermal energy development in the state of California as of the early part of 1976. The report provides data on the extent of the resource base of the state and the present outlook for its utilization. It identifies the existing local, state, and federal laws, rules and regulations governing geothermal energy development and the responsibilities of each of the regulatory agencies involved. It also presents the differences in the development requirements among several counties and between California and its neighboring states. Finally, it describes on-going and planned activities in resource assessment and exploration, utilization, and research and development. Separate abstracts are prepared for ERDA Energy Research Abstracts (ERA) for Sections II--VI and the three Appendixes.

    Transactive energy refers to the combination of economic and control techniques to improve grid reliability and efficiency. The fundamental purpose of transactive energy management is to seamlessly coordinate the operation of large numbers of new intelligent assets—such as distributed solar, energy storage and responsive building loads—to provide the flexibility needed to operate the power grid reliably and at minimum cost, particularly one filled with intermittent renewable generation such as the Pacific Northwest. It addresses the key challenge of providing smooth, stable, and predictable “control” of these assets, despite the fact that most are neither owned nor directly controlled by the power grid. The Clean Energy and Transactive Campus (CETC) work described in this report was done as part of a Cooperative Research and Development Agreement (CRADA) between the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) and the Washington State Department of Commerce (Commerce) through the Clean Energy Fund (CEF). The project team consisted of PNNL, the University of Washington (UW) and Washington State University (WSU), to connect the PNNL, UW, and WSU campuses to form a multi-campus testbed for transaction-based energy management—transactive—solutions. Building on the foundational transactive system established by the Pacific Northwest Smart Grid Demonstration (PNWSGD), the purpose of the project was to construct the testbed as both a regional flexibility resource and as a platform for research and development (R&D) on buildings/grid integration and information-based energy efficiency. This report provides a summary of the various tasks performed under the CRADA.

    This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The authors investigated the evolution and radiation characteristics of individual neutron stars and stellar systems. The work concentrated on phenomena where new techniques and observations are dramatically enlarging the understanding of stellar phenomena. Part of this project was a study of x-ray and gamma-ray emission from neutron stars and other compact objects. This effort included calculating the thermal x-ray emission from young neutron stars, deriving the radio and gamma-ray emission from active pulsars and modeling intense gamma-ray bursts in distant galaxies. They also measured periodic optical and infrared fluctuations from rotating neutron stars and search for high-energy TeV gamma rays from discrete celestial sources.

  11. Energy Efficiency Improvement and Cost Saving Opportunities for the Vehicle Assembly Industry: An ENERGY STAR Guide for Energy and Plant Managers

    Galitsky, Christina; Galitsky, Christina; Worrell, Ernst

    2008-01-01

    The motor vehicle industry in the U.S. spends about $3.6 billion on energy annually. In this report, we focus on auto assembly plants. In the U.S., over 70 assembly plants currently produce 13 million cars and trucks each year. In assembly plants, energy expenditures is a relatively small cost factor in the total production process. Still, as manufacturers face an increasingly competitive environment, energy efficiency improvements can provide a means to reduce costs without negatively affecting the yield or the quality of the product. In addition, reducing energy costs reduces the unpredictability associated with variable energy prices in today?s marketplace, which could negatively affect predictable earnings, an important element for publicly-traded companies such as those in the motor vehicle industry. In this report, we first present a summary of the motor vehicle assembly process and energy use. This is followed by a discussion of energy efficiency opportunities available for assembly plants. Where available, we provide specific primary energy savings for each energy efficiency measure based on case studies, as well as references to technical literature. If available, we have listed costs and typical payback periods. We include experiences of assembly plants worldwide with energy efficiency measures reviewed in the report. Our findings suggest that although most motor vehicle companies in the U.S. have energy management teams or programs, there are still opportunities available at individual plants to reduce energy consumption cost effectively. Further research on the economics of the measures for individual assembly plants, as part of an energy management program, is needed to assess the potential impact of selected technologies at these plants.

    2013-07-01

    This document reports an audit study performed by the ADEME and related to energy social tariffs, to their modalities and distribution costs, and aimed at proposing recommendations to improve these arrangements or to create a new one. In a first part, it outlines that these tariffs are apparently based on simple and fair principles, describes how eligible households are identified, outlines that these tariffs do not solve arrangement structural inequity between heating modes, that the awarded amount depends on too many parameters, that providers are totally reimbursed (sometimes even more), and that the arrangement is still insufficient to solve the problem of energy poverty. The second part addresses operational modalities and highlights their complexity. Recommendations are then stated which are aimed at consolidating and simplifying them, and at modifying them to create an actual energy shield

    Iraq is already the world’s third largest oil exporter. It has the resources and intention to increase its oil production vastly. Contracts are already in place. Will Iraq’s ambitions be realised? And what would the implications be for Iraq’s economy and for world oil markets? The obstacles are formidable: political, logistical, legal, regulatory, financial, lack of security and sufficient skilled labour. One example: in 2011 grid electricity could meet only 55% of demand. The International Energy Agency has studied these issues with the support and close cooperation of the government of Iraq and many other leading officials, commentators, industry representatives and international experts. This special report, in the World Energy Outlook series, presents the findings.

Demonstrate improved grid asset utilization by storing energy during off-peak periods for dispatch during local load peaks. 4. Establish an advanced battery manufacturing industry in the U.S. 5. Reduce CO2 emissions from utilities. This report summarizes the key milestones, data, results and lessons learned from the project. The desired goals and benefits of the cooperative agreement with the DOE have all been achieved. The project has contributed to reducing power costs, accelerating adoption of renewable energy resources, reducing greenhouse gas emissions and establishing advanced battery manufacturing in the U.S. The Recovery Act funds provided thru the DOE have been leveraged multiple times by additional private equity investment. Primus Power continues to ship low cost, long life and long duration EnergyPod® flow battery systems to utilities, commercial/industrial, microgrid and data center customers. After the conclusion of this project, Primus Power has modified the EnergyPod® design to optimize around energy performance. Primus Power has moved to a prefabricated enclosure instead of multiple EnergyCells in a container. This lowers capital and maintenance costs and can optimize site design. Utilities are starting to adopt energy storage for a variety of functions. The market will grow as the technology is proven and profitable applications expand.

    Context. Runaway stars form bow shocks by ploughing through the interstellar medium at supersonic speeds and are promising sources of non-thermal emission of photons. One of these objects has been found to emit non-thermal radiation in the radio band. This triggered the development of theoretical models predicting non-thermal photons from radio up to very-high-energy (VHE, E ≥ 0.1 TeV) gamma rays. Subsequently, one bow shock was also detected in X-ray observations. However, the data did not allow discrimination between a hot thermal and a non-thermal origin. Further observations of different candidates at X-ray energies showed no evidence for emission at the position of the bow shocks either. A systematic search in the Fermi-LAT energy regime resulted in flux upper limits for 27 candidates listed in the E-BOSS catalogue. Aim. Here we perform the first systematic search for VHE gamma-ray emission from bow shocks of runaway stars. Methods: Using all available archival H.E.S.S. data we search for very-high-energy gamma-ray emission at the positions of bow shock candidates listed in the second E-BOSS catalogue release. Out of the 73 bow shock candidates in this catalogue, 32 have been observed with H.E.S.S. Results: None of the observed 32 bow shock candidates in this population study show significant emission in the H.E.S.S. energy range. Therefore, flux upper limits are calculated in five energy bins and the fraction of the kinetic wind power that is converted into VHE gamma rays is constrained. Conclusions: Emission from stellar bow shocks is not detected in the energy range between 0.14 and 18 TeV.The resulting upper limits constrain the level of VHE gamma-ray emission from these objects down to 0.1-1% of the kinetic wind energy.

    Full Text Available Star fruit (Avarrhoa carambola is a fruit from oxalidace family. lt is found in many countries of the world including Bangladesh. But its ingestion or drinking star fruit juice may lead to intoxication especially in patients with chronic kidney disease and manifestations might be neurological or nephrological. lt may also cause acute kidney injury in patients with previously normal renal function. Here we are presenting a case who presented with acute kidney injury after star fruit ingestion with previously unknown renal function impairment. The etiology was confirmed by histopathological exami­nation after doing renal biopsy. This renal function impairment is mainly due to oxalate crystal induce nephropathy which is richly abundant in star fruit. His renal function was improved ·with conservative management. Physicians should be alert to consider the ingestion of star fruit as a cause of acute kidney injury in a patient even in the absence of previous renal function impairment.

    Full Text Available Development of the concepts of sustainable development and corporate social responsibility has a great impact on reporting in companies. The increase of their importance has resulted in a need to create a reporting system that would provide information on not only the methods but also the results of implementation of those concepts in companies. Globally, there are many organizations that promote and support companies in the area of integrated reporting. The most popular standard for reporting non-financial data that is used by a number of companies worldwide is the Global Reporting Initiative (GRI Guidelines. The main objective of the GRI is to support the development of sustainable economy in which companies take responsibility for the economic, social, and environmental consequences of their operations, manage that responsibility, and report all their actions. An example of a sector where the concept of sustainable development and its transparent reporting has an impact on the formation of values is the energy sector, which creates value for stakeholders and, together with the financial sector, has the greatest impact on national economies.

    Most elements are synthesized, or ""cooked"", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book

    One of the great challenges in the transition to a non-fossil energy system with a high share of fluctuating renewable energy sources such as solar and wind is to align consumption and production in an economically satisfactory manner. Energy storage could provide the necessary balancing power to make this possible. This energy report addresses energy storage from a broad perspective: It analyses smaller stores that can be used locally in for example heat storage in the individual home or vehicle, such as electric cars or hydrogen cars. The report also addresses decentralized storage as flywheels and batteries linked to decentralized energy systems. In addition it addresses large central storages as pumped hydro storage and compressed air energy storage and analyse this in connection with international transmission and trading over long distances. The report addresses electrical storage, thermal storage and other forms of energy storage, for example conversion of biomass to liquid fuel and conversion of solar energy directly into hydrogen, as well as storage in transmission, grid storage etc. Finally, the report covers research, innovation and the future prospects and addresses the societal challenges and benefits of the use of energy storage.

  12. Sounds of a Star

    colours show element displacements in opposite directions. Geologists monitor how seismic waves generated by earthquakes propagate through the Earth, and thus learn about the inner structure of our planet. The same technique works for stars. The Sun, our nearest star and a typical middle-age member of its class, has been investigated in this way since the 1960's. With "solar seismology" , astronomers have been able to learn much about the inner parts of the star, and not only the outer layers normally visible to the telescopes. In the Sun, heat is bubbling up from the central regions where enormous amount of energy is created by nuclear reactions . In the so-called convective zone , the gas is virtually boiling, and hot gas-bubbles are rising with a speed that is close to that of sound. Much like you can hear when water starts to boil, the turbulent convection in the Sun creates noise . These sound waves then propagate through the solar interior and are reflected on the surface, making it oscillate. This "ringing" is well observed in the Sun, where the amplitude and frequency of the oscillations provide astronomers with plenty of information about the physical conditions in the solar interior. From the Sun to the stars There is every reason to believe that our Sun is a quite normal star of its type. Other stars that are similar to the Sun are therefore likely to pulsate in much the same way as the Sun. The search for such oscillations in other solar-like stars has, however, been a long and difficult one. The problem is simply that the pulsations are tiny, so very great precision is needed in the measurements. However, the last few years have seen considerable progress in asteroseismology, and François Bouchy and Fabien Carrier from the Geneva Observatory have now been able to detect unambiguous acoustic oscillations in the Solar-twin star, Alpha Centauri A. The bright and nearby star Alpha Centauri Alpha Centauri (Alpha Cen) [1] is the brightest star in the constellation

    This study reports data from Swedish investigations of attitudes towards different technologies for producing energy and energy conservation. The study surveys opinion polls and research made between 1978 and 1988. The results demonstrate the excessive interest in nuclear power which was in focus in a majority of the studies during that time. The results indicate that the Swedish public oscillates around 50 per cent for nucclear power and 50 per cent against. A number of studies of nuclear power attitudes were reviewed including topics such as worry, behavior following the Chernobyl fallout, beliefs about risks of Swedish program and policy issues regarding the phasing out of the Swedish nuclear power program. Preferences for alternatives to nuclear power were investigated in a series of studies. Here, hydropower was the single leading alternative; solar, wind and natural gas were other preferred alternatives. Attitudes to other energy sources were also summarized in the present study. The study concludes with some remarks on future directions of research on the public's perception of the production and the use of energy. (authors)

    The Energy Market Review Releases draft report has made recommendations consistent with the Australian Gas Association (AGA)'s submissions in a number of areas. In particular, it has endorsed: 1. the need for an independent review of the gas access regime, to address the deficiencies with current access regulation identified by the Productivity Commission's Review of the National Access Regime; 2. the need for greater upstream gas market competition; 3. the principle that significant regulatory decisions should be subject to clear merits and judicial review; and 4. the need to avoid restrictions on retail energy prices. The report also endorses the need for a 'technology neutral' approach to greenhouse emissions abatement policy. It states that 'many of the current measures employed to reduce greenhouse gas emissions are poorly targeted', and that they 'target technologies or fuel types rather than greenhouse gas abatement.' Additionally, it explicitly recognises the key conclusions of the AGA's recently-released Research Paper, Reducing Greenhouse Emissions from Water Heating: Natural Gas as a Cost-effective Option. The draft report recommends the development of an economy-wide emissions trading system, to achieve a more cost-effective approach to greenhouse abatement

    Calgary based Sustainable Energy Technologies is a public company that develops and manufactures alternative energy products that enable distributed renewable energy resources to be integrated with the existing electrical infrastructure. The company has moved from a development stage company to one that manufactures power electronic products that can compete globally and which will play an important role in the transition to a cleaner world. Achievements in the past year have included a joint effort with RWE Piller GmbH to develop a power electronics platform for a fuel cell inverter. Ten inverters were delivered to Nuvera Fuel Cells and were reported to have performed very well in the Avanti distributed generation fuel cell. The universality of the inverter was demonstrated when the same power electronics platform was used to support a 5 kW grid interactive converter for the solar power market. During the 18-month period ending on March 31, 2003, the company invested $1.5 million to create their first two commercial product lines, without net investment of shareholder equity. The objective for the future is to generate cash flow and earnings from sales into the solar power market and to build a leadership role in the stationary fuel cell industry. The major challenge will lie in product support and customer service. As the customer base expands, the company will invest in product-tracking software. This annual report includes an auditor's report, consolidated financial statements including balance sheets, statements of income and deficit, statements of cash flows, and notes to the consolidated financial statements. tabs

    1996-01-01

    Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission's Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty. Of the many worthwhile projects, four were chosen to represent best the current trends in the continuing R and D program at the research centers of the Israel Atomic Energy Commission. One of these trends is the growing cooperation with private industry, in an attempt to gear our R and D programs to respond to market demands. Another feature, noted already several years ago, is the extensive collaboration of our scientists and engineers with colleagues at other institutions, in Israel and abroad. some of the work reported is part of evolving international industrial cooperation projects, illustrating both these trends. Following a trend common to many nuclear research centers around the world, a substantial part of our research effort is non-nuclear in nature. This is illustrated in the first article, which deals with advances in the application of non-linear optics in diverse fields of science and technology. These include state-of-the-art solid-state lasers, rapid modulation of light signals, development and generation of tunable sources of coherent light, optical data storage and the microscopic probing of biological and inorganic samples. The present work reports on a range of R and D, from the fundamentals of non-linear optical materials to proof-of-principle demonstrations of non-linear subwavelength resolution microscopy, to fabrication of prototype commercial tunable laser systems The second report considers the microstrain characteristics in some alloys using X-ray diffraction (XRD). The research utilizes XRD line broadening effects to study the characteristics of alloys from especially prepared surfaces. These characteristics include the homogeneity of alloying

    This is a NEDO (New Energy and Industrial Technology Development Organization) report on alternate energy dated July 15, 1989 (based on a Koleda Childress and Company of EPA analysis). Development of fossil and synthetic fuels in the United States is stated. President Bush on July 12 proposed amendments to the Clean Air Act of 1970. The amendments involve acid rain, urban air pollution, and toxic air pollutants. The proposal will greatly influence the development of new energies, especially in relation to clean coal technology and increase in the use of methanol as alternate automobile fuel. The power and coal industries will be requested, with attention paid to the SOx and NOx emissions reduction schedule, to operate scrubbers, burn low-sulfur coal, convert to natural gas, and to close old facilities. Long-term clean fuel programs will be amalgamated with the proposal of President Bush, and production of methanol-driven automobiles and their fuel will be given a boost. Such will be effected in nine heavily-polluted cities for an increase from 500,000 automobiles in 1995 to 8,250,000 in 2004. Reference is also made to the budget. (NEDO)

    We report the main results of study performed at CERN over the last three years by few people and with shoe-string funding on the potential impact of new Accelerators technologies in the field of Energy production from nuclei. Accelerators have been universal tools to nuclear reactions : why not using them to produce practical, sizeable amounts of nuclear transmutations, i.e. to: 1. eliminate unwanted long-lived, radioactive Waste from LWR's; 2. (eventually to produce energy in non-critical conditions, similar to the promises of Fusion and 3. as a substitution of Reactors for the neutron activation of short-lived radioactive elements for industrial and medical applications. - We have studied at the CERN-PS both the energy (heat) produced in nuclear cascades in a sub-critical environment (k=0.90) and the transmutation of unwanted waste in a small lethargy, transparent medium (lead). These experiments have been driven by conceptual studies and elaborate computer simulations of nuclear cascades and extend the we...

    Union Gas Limited, a subsidiary of Westcoast Energy Company, is a major Canadian natural gas utility, providing energy delivery and related services to 1.1 million residential, commercial and industrial customers in over 400 communities in northern, southwestern and eastern Ontario. Union Gas also provides natural gas storage and transportation services for other utilities and energy market participants in Ontario, Quebec and the northeastern United States. In 1999 the Company had revenues of 1.5 billion, net income of $ 95 million, and assets totalling $ 3.8 billion. Net income was down from $ 109 million in 1998, due mainly to the impact of the sale of the Company's retail merchandise program to Union Energy, a lower approved rate of return on common equity. Full-time employees number about 2,500. Total throughput for 1999 was 34.6 billion cubic metres of natural gas, up 8.9 per cent from 1998. The Company undertook significant reorganization and restructuring during 1999, to emphasize critical business processes. The reorganization, which saw the divestiture of the retail merchandise programs to an unregulated affiliate, Union Energy, resulted in a flat, flexible and efficient enterprise, more capable of timely response to changing market opportunities and customer needs. Union Gas also filed application with the Ontario Energy Board for rates for the year 2000 and beyond, using the performance-based regulation framework; completed construction of a $ 16 million, 90 km pipeline to make natural gas service available to Parry Sound; Launched 'enoms' a new Internet-based natural gas nominations system; completed the first phase of the $ 17 million Century Pools storage development project, and applied to build the second phase, comprising a $37 million addition to the storage pools at the Mandasumin, Bluewater and Oil City pools; and completed several smaller projects totalling $ 5.2 million to give access to natural gas to 2,300 new customers at various parts of

    There are some arguments that the symbiotic stars are binary, where one component is a red giant and the other component is a small hot star which is exciting a nebula. The symbiotic stars belong to the old disc population. Probably, symbiotic stars are just such an evolutionary stage for double stars as planetary nebulae for single stars. (Auth.)

    WWF has a vision of a world that is powered by 100 per cent renewable energy sources by the middle of this century. Unless we make this transition, the world is most unlikely to avoid predicted escalating impacts of climate change. But is it possible to achieve 100 per cent renewable energy supplies for everyone on the planet by 2050? WWF called upon the expertise of respected energy consultancy Ecofys to provide an answer to this question. In response, Ecofys has produced a bold and ambitious scenario - which demonstrates that it is technically possible to achieve almost 100 per cent renewable energy sources within the next four decades. The Ecofys scenario raises a number of significant issues and challenges. The Energy Report investigates the most critically important political, economic, environmental and social choices and challenges, and encourages their further debate. How are we going to provide for all of the world's future needs, on energy, food, fibre, water and others, without running into such huge issues as: conflicting demands on land/water availability and use; rising, and in some cases, unsustainable consumption of commodities; nuclear waste; and regionally appropriate and adequate energy mixes? The world needs to seriously consider what will be required to transition to a sustainable energy future, and to find solutions to the dilemmas raised in this report. Answering these challenges - the solutions to the energy needs of current and future generations is one of the most important, challenging and urgent political tasks ahead

    The Young - Rainey STAR Center (Science, Technology, and Research Center) at the Pinellas County, Florida, Site is a former U.S. Department of Energy (DOE) facility constructed in the mid-1950s. The 96-acre STAR Center is located in Largo, Florida, and lies in the northeast quarter of Section 13, Township 30 South, Range 15 East (Figure 1). While it was owned by DOE, the purpose of the site was to develop and manufacture components for the nation’s nuclear weapons program. In 1987, the U.S. Environmental Protection Agency (EPA) performed a Resource Conservation and Recovery Act Facility Assessment (EPA 1988) at the site to gather information on potential releases of hazardous materials. In February of 1990, EPA issued a Hazardous and Solid Waste Amendments permit to DOE, requiring DOE to investigate and perform remediation activities in those areas designated as solid-waste management units (SWMUs) contaminated by hazardous materials resulting from DOE operations. A total of 17 SWMUs were identified and investigated at the STAR Center. By 1997, 13 of the 17 SWMUs had been remediated or approved for no further action. More recently, the Florida Department of Environmental Protection (FDEP) executed Conditional Site Rehabilitation Completion Orders for the Northeast Site and the Wastewater Neutralization Area on July 27, 2016, stating that no further action is required for those SWMUs. The Building 100 Area (a combination of the Old Drum Storage Site and the Building 100-Industrial Drain Leaks SWMUs) comprises the only two active SWMUs at the STAR Center (Figure 2). This document serves as the semiannual progress report for the SWMUs by providing the results of recent monitoring activities and a summary of ongoing and projected work. The STAR Center is owned by the Pinellas County Industrial Development Authority, but DOE is responsible for remediation activities at the site. Additional background information for the site is contained in the Long-Term Surveillance

    2012-01-01

    We present a study on spectral energy distributions, morphologies, and star formation for an IRAC-selected extremely red object sample in the GOODS Chandra Deep Field-South. This work was enabled by new HST/WFC3 near-IR imaging from the CANDELS survey as well as the deepest available X-ray data from Chandra 4 Ms observations. This sample consists of 133 objects with the 3.6 μm limiting magnitude of [3.6] = 21.5 and is approximately complete for galaxies with M * > 10 11 M ☉ at 1.5 ≤ z ≤ 2.5. We classify this sample into two types, quiescent and star-forming galaxies (SFGs), in the observed infrared color-color ([3.6]–[24] versus K – [3.6]) diagram. The further morphological study of this sample shows a consistent result with the observed color classification. The classified quiescent galaxies are bulge dominated and SFGs in the sample have disk or irregular morphologies. Our observed infrared color classification is also consistent with the rest-frame color (U – V versus V – J) classification. We also found that quiescent and SFGs are well separated in the nonparametric morphology parameter (Gini versus M 20 ) diagram measuring their concentration and clumpiness: quiescent galaxies have a Gini coefficient higher than 0.58 and SFGs have a Gini coefficient lower than 0.58. We argue that the star formation quenching process must lead to or be accompanied by the increasing galaxy concentration. One prominent morphological feature of this sample is that disks are commonly seen in this massive galaxy sample at 1.5 ≤ z ≤ 2.5: 30% of quiescent galaxies and 70% of SFGs with M * > 10 11 M ☉ have disks in their rest-frame optical morphologies. The prevalence of these extended, relatively undisturbed disks challenges the merging scenario as the main mode of massive galaxy formation.

    The mission of the Energy Materials Center at Cornell (emc2) was to achieve a detailed understanding, via a combination of synthesis of new materials, experimental and computational approaches, of how the nature, structure, and dynamics of nanostructured interfaces affect energy conversion and storage with emphasis on fuel cells, batteries and supercapacitors. Our research on these systems was organized around a full system strategy for; the development and improved performance of materials for both electrodes at which storage or conversion occurs; understanding their internal interfaces, such as SEI layers in batteries and electrocatalyst supports in fuel cells, and methods for structuring them to enable high mass transport as well as high ionic and electronic conductivity; development of ion-conducting electrolytes for batteries and fuel cells (separately) and other separator components, as needed; and development of methods for the characterization of these systems under operating conditions (operando methods) Generally, our work took industry and DOE report findings of current materials as a point of departure to focus on novel material sets for improved performance. In addition, some of our work focused on studying existing materials, for example observing battery solvent degradation, fuel cell catalyst coarsening or monitoring lithium dendrite growth, employing in operando methods developed within the center.

    The report describes the development of a highly effective ammonia heat pump. Heat pumps play an increasingly important role in the search for more effective use of energy in our society. Highly efficient heat pumps can contribute to reduced energy consumption and improved economy of the systems which they are a part of. An ammonia heat pump with high pressure reciprocating compressor and a novel split condenser was developed to prove potential for efficiency optimization. The split of the condenser in two parts can be utilized to obtain smaller temperature approaches and, thereby, improved heat pump efficiency at an equal heat exchanger area, when compared to the traditional solution with separate condenser and de-superheater. The split condenser design can also be exploited for heating a significant share of the total heating capacity to a temperature far above the condensing temperature. Furthermore, the prototype heat pump was equipped with a plate type evaporator combined with a U-turn separator with a minimum liquid height and a liquid pump with the purpose of creating optimum liquid circulation ratio for the highest possible heat transfer coefficients at the lowest possible pressure drop. The test results successfully confirmed the highest possible efficiency; a COP of 4.3 was obtained when heating water from 40 deg. C to 80 deg. C while operating with evaporating/condensing temperatures of +20 deg C/+73 deg C. (Author)

    Latvia has only a few indigenous energy resources that are concentrated on hydro-power, wood and peat. The country is therefore strongly dependant on imports of natural gas, oil, coal and electricity. After independence the supply of natural gas, oil and electricity were organised by three state owned joint-stock companies, Latvijas Gaze, Latvijas Nafta and Latvenergo. Partial privatisation of the gas and oil companies has been decided by the Latvian government but so far not implemented. Two types of models have been used within the Energy Tariff Project: The EFOM model that was developed and implemented for Latvia as a part of the EURIO project has been adapted to describe the long term reactions for the electricity and district heating sectors; A system of Customer Calculation Sheets for the analysis of consumer expenditure and utility revenue. The optimization model for the electricity and CHP system is also used to analyze the impact of gas tariffs for the electricity and district heating sector within geographical or institutional limits. In this report the following regions are specified: City of Riga; Other district heating areas; Rest of Latvia. The Danish tariff structure for natural gas was reviewed. The present structure is presently market orientated with direct links to the price movements of alternative fuels for all customer groups. (EG) 50 refs

    We report on the first 10 identifications of sources serendipitously detected by the Nuclear Spectroscopic Telescope Array (NuSTAR) to provide the first sensitive census of the cosmic X-ray background source population at approximately greater than 10 keV. We find that these NuSTAR-detected sources are approximately 100 times fainter than those previously detected at approximately greater than 10 keV and have a broad range in redshift and luminosity (z = 0.020-2.923 and L(sub 10-40 keV) approximately equals 4 × 10(exp 41) - 5 × 10(exp 45) erg per second; the median redshift and luminosity are z approximately equal to 0.7 and L(sub 10-40 keV) approximately equal to 3 × 10(exp 44) erg per second, respectively. We characterize these sources on the basis of broad-band approximately equal to 0.5 - 32 keV spectroscopy, optical spectroscopy, and broad-band ultraviolet-to-mid-infrared spectral energy distribution analyses. We find that the dominant source population is quasars with L(sub 10-40 keV) greater than 10(exp 44) erg per second, of which approximately 50% are obscured with N(sub H) approximately greater than 10(exp 22) per square centimeters. However, none of the 10 NuSTAR sources are Compton thick (N(sub H) approximately greater than 10(exp 24) per square centimeters) and we place a 90% confidence upper limit on the fraction of Compton-thick quasars (L(sub 10-40 keV) greater than 10(exp 44) erg per second) selected at approximately greater than 10 keV of approximately less than 33% over the redshift range z = 0.5 - 1.1. We jointly fitted the rest-frame approximately equal to 10-40 keV data for all of the non-beamed sources with L(sub 10-40 keV) greater than 10(exp 43) erg per second to constrain the average strength of reflection; we find R less than 1.4 for gamma = 1.8, broadly consistent with that found for local active galactic nuclei (AGNs) observed at approximately greater than 10 keV. We also constrain the host-galaxy masses and find a median stellar

    My thesis centers around the study of neutron stars, especially those in massive binary systems. To this end, it has two distinct components: the observational study of neutron stars in massive binaries with a goal of measuring neutron star masses and participation in NuSTAR, the first imaging hard X-ray mission, one that is extremely well suited to the study of massive binaries and compact objects in our Galaxy. The Nuclear Spectroscopic Telescope Array (NuSTAR) is a NASA Small Explorer mission that will carry the first focusing high energy X-ray telescope to orbit. NuSTAR has an order-of-magnitude better angular resolution and has two orders of magnitude higher sensitivity than any currently orbiting hard X-ray telescope. I worked to develop, calibrate, and test CdZnTe detectors for NuSTAR. I describe the CdZnTe detectors in comprehensive detail here - from readout procedures to data analysis. Detailed calibration of detectors is necessary for analyzing astrophysical source data obtained by the NuSTAR. I discuss the design and implementation of an automated setup for calibrating flight detectors, followed by calibration procedures and results. Neutron stars are an excellent probe of fundamental physics. The maximum mass of a neutron star can put stringent constraints on the equation of state of matter at extreme pressures and densities. From an astrophysical perspective, there are several open questions in our understanding of neutron stars. What are the birth masses of neutron stars? How do they change in binary evolution? Are there multiple mechanisms for the formation of neutron stars? Measuring masses of neutron stars helps answer these questions. Neutron stars in high-mass X-ray binaries have masses close to their birth mass, providing an opportunity to disentangle the role of "nature" and "nurture" in the observed mass distributions. In 2006, masses had been measured for only six such objects, but this small sample showed the greatest diversity in masses

    We report the first hard X-ray (3-79 keV) observations of the millisecond pulsar (MSP) binary PSR J1023+0038 using NuSTAR. This system has been shown transiting between a low-mass X-ray binary (LMXB) state and a rotation-powered MSP state. The NuSTAR observations were taken in both LMXB state and rotation-powered state. The source is clearly seen in both states up to ∼79 keV. During the LMXB state, the 3-79 keV flux is about a factor of 10 higher than in the rotation-powered state. The hard X-rays show clear orbital modulation during the X-ray faint rotation-powered state but the X-ray orbital period is not detected in the X-ray bright LMXB state. In addition, the X-ray spectrum changes from a flat power-law spectrum during the rotation-powered state to a steeper power-law spectrum in the LMXB state. We suggest that the hard X-rays are due to the intrabinary shock from the interaction between the pulsar wind and the injected material from the low-mass companion star. During the rotation-powered MSP state, the X-ray orbital modulation is due to Doppler boosting of the shocked pulsar wind. At the LMXB state, the evaporating matter of the accretion disk due to the gamma-ray irradiation from the pulsar stops almost all the pulsar wind, resulting in the disappearance of the X-ray orbital modulation.

    What impact will the return of high energy prices have on the fragile economic recovery? Will geopolitical unrest, price volatility and policy inaction defer investment in the oil sector and amplify risks to our energy security? What will renewed uncertainty surrounding the role of nuclear power mean for future energy and environmental trends? Is the gap between our climate actions and our climate goals becoming insurmountable? World Energy Outlook 2011 tackles these and other pressing questions. The latest data, policy developments, and the experience of another turbulent year are brought together to provide robust analysis and insight into global energy markets. WEO-2011 once again gives detailed energy demand and supply projections out to 2035, broken down by region, fuel, sector and scenario.

  5. Recent results on event-by-event fluctuations from the RHIC Beam Energy Scan program in the STAR experiment

    2014-01-01

    Event-by-event fluctuations of global observables in relativistic heavy-ion collisions are studied as probes for the QCD phase transition and as tools to search for critical phenomena near the phase boundary. Dynamical fluctuations in mean transverse momentum, identified particle ratios and conserved quantities (such as net-charge, net-baryon) are expected to provide signatures of a de-confined state of matter. Non-monotonic behavior in the higher-moments of conserved quantities as a function of beam energy and collision centrality are proposed as signatures of the QCD critical point. To study the QCD phase transition and locate the critical point, the STAR experiment at RHIC has collected a large amount of data for Au+Au collisions from √S_N_N = 7.7 - 200 GeV in the RHIC Beam Energy Scan (BES) program. We present the recent beam energy scan results on dynamical fluctuations of particle ratios and two-particle transverse momentum correlations at mid-rapidity. Higher-moments of the net-charge and net-proton multiplicity distributions as a function of beam energy will be presented. We give a summary of what has been learnt so far and future prospectives for the BES-II program.

    A study was conducted to better understand energy issues in the Yukon. The study was based on the Yukon Energy Matrix which looks at the Yukon energy sector from the perspective of the capacity to supply various forms of energy, the markets for energy in the Yukon, and energy users. The sources of non-renewable energy in the Yukon range from natural gas, coal and oil. Renewable energy sources are also diverse and include water, biomass, wind, solar and geothermal. The main sources of electricity production in the Yukon are oil, water and wind. The link between energy and climate change has gained much attention in recent years, resulting in effective measures to conserve energy and increase energy efficiency. Coal, gas and oil are imported into the Yukon from markets in southern Alaska despite the fact that Yukon has its own vast quantities of these fossil-based forms of energy. As a result, the price of fossil-fuels consumed in the Yukon is determined in national and international markets. The absence of non-renewable energy production in the Yukon is also reflected in the lack of pipeline and rail infrastructure in the territory. The Yukon's electricity transmission grid is also very fragmented. For the purpose of this paper, energy use was categorized into the residential, commercial, industrial and transportation sectors. 19 refs., 8 tabs., 12 figs

    Background Low-energy reporters (LERs) and non-LERs differ with respect to a number of characteristics, including self-reported intake of foods. Limited data exists investigating food intake differences with LERs identified using doubly labeled water (DLW). Objective In the Observing Protein and Energy Nutrition Study (September, 1999-March, 2000), differences were examined between food group reports of LERs and non-LERs on a food frequency questionnaire (FFQ) (n=440). Design LERs were identified using DLW. LERs' (n=220) and non-LERs' (n=220) reports of 43 food groups on the FFQ were examined in three ways: whether they reported consuming a food group (yes/no), how frequently they reported consuming it (times/day), and the reported portion size (small, medium, or large). Analyses were adjusted for total energy expenditure from DLW. Results LERs compared to non-LERs were less likely to report consumption for one food group among women (soft drinks/regular) and no food groups among men. Reported mean daily frequency of consumption was lower in LERs compared to non-LERs for 23 food groups among women and 24 food groups among men (18 food groups were similar in men and women). Additionally, reported mean portion sizes were smaller for LERs compared to non-LERs for 6 food groups among women and 5 food groups among men (3 food groups were similar in men and women). Results varied minimally by sex and body mass index (BMI). Conclusions LERs as compared to non-LERs were more likely to differ regarding their reported frequency of consumption of food groups than their reported consumption (yes/no) of the food groups or the food groups' reported portion sizes. Results did not vary greatly by sex or BMI. It still remains to be known whether improvement in questionnaire design or additional tools or methods would lead to a decrease in differential reporting due to LER status on an FFQ. PMID:19559136

    International Nuclear Information System (INIS)

    2000-12-01

    The review consists of the most recent and settled data for the year 1999 as well as for the preceding four years. In 1999 total energy consumption increased by 4.5 percent compared to the previous year. As at the same time the gross domestic product decreased by 0.3 percent, energy intensity grew, thus presenting negative trend. The energy intensity, the measurement showing the total energy consumption per unit of gross domestic product, exceeded the level realised by the Western European countries, but was still more favourable than in most transition countries. At the same time 1999 saw an increase of primary energy generation by 1.5 percent but, as a consequence of extremely favourable hydrological conditions, with a decreased production of natural gas and oil. This caused a drop of the supply from own sources to 50.4 percent, the lowest value so far. This trend is expected to continue in the following few years bearing in mind the condition of the gas and oil reserves, i.e. cessation of coal production in Istria. Only partly will the process be slowed down by the production of natural gas from the Northern Adriatic. In 1999 the transformation losses rose by 7.3 percent, energy sector own use by 4.5 percent and non-energy consumption by 14.2 percent. Transportation and distribution losses fell by 9.9 percent. The result of this was that, despite the increase of total energy production by 4.5 percent, final energy demand grew by only 3.4 percent: 7.5 percent in transport, 4.5 percent in other sectors, and a 4.4 percent decrease in industry. Apart from these data, the publication includes all other relevant indicators about our energy system, i.e. system capacities, energy source prices, environmental influence, etc

    This report estimates historical data center electricity consumption back to 2000, relying on previous studies and historical shipment data, and forecasts consumption out to 2020 based on new trends and the most recent data available. Figure ES-1 provides an estimate of total U.S. data center electricity use (servers, storage, network equipment, and infrastructure) from 2000-2020. In 2014, data centers in the U.S. consumed an estimated 70 billion kWh, representing about 1.8% of total U.S. electricity consumption. Current study results show data center electricity consumption increased by about 4% from 2010-2014, a large shift from the 24% percent increase estimated from 2005-2010 and the nearly 90% increase estimated from 2000-2005. Energy use is expected to continue slightly increasing in the near future, increasing 4% from 2014-2020, the same rate as the past five years. Based on current trend estimates, U.S. data centers are projected to consume approximately 73 billion kWh in 2020.

    Current DOE plans call for building an Energy Applied Systems Test (EAST) Facility at the Savannah River Plant in close proximity to the 140 to 150/sup 0/F waste heat from one of several operating nuclear reactors. The waste water flow from each reactor, approximately 165,000 gpm, provides a unique opportunity to test the performance and operating characteristics of large-scale waste heat power generation and heat pump system concepts. This report provides a preliminary description of the potential end-use market, parametric data on heat pump and the power generation system technology, a preliminary listing of EAST Facility requirements, and an example of an integrated industrial park utilizing the technology to maximize economic pay back. The parametric heat pump analysis concluded that dual-fluid Rankine cycle heat pumps with capacities as high as 400 x 10/sup 6/ Btu/h, can utilize large sources of low temperature residual heat to provide 300/sup 0/F saturatd steam for an industrial park. The before tax return on investment for this concept is 36.2%. The analysis also concluded that smaller modular heat pumps could fulfill the same objective while sacrificing only a moderate rate of return. The parametric power generation analysis concluded that multi-pressure Rankine cycle systems not only are superior to single pressure systems, but can also be developed for large systems (approx. = 17 MW/sub e/). This same technology is applicable to smaller systems at the sacrifice of higher investment per unit output.

    1999-01-01

    Crestar Energy Inc. is a senior Canadian oil and gas producer operating in western Canada. In 1998, in spite of the collapse in oil prices, cash flow per unit of production improved during every quarter of the year. The company's operating results for the year were solid, fuelled by a three-tiered strategy of development, acquisition and and exploration. Exploration efforts are directed equally towards natural gas and liquid projects, while development activity is driven by near term commodity prices. This three-tiered strategy ensures steady growth at the present, and provides the foundation for accelerated growth over the longer term. This report presents a review of operations, including a 12 per cent increase in sales volume for both natural gas and liquids from 1997 to average 401 mmcf/day and 49,000 bbls/day respectively. Significant additions were made to the natural gas reserves, while crude oil reserves were slightly reduced by economic limit revisions of 3.5 mmBOE. Finding and development costs for established reserves, before economic limit revisions, were $ 7.73 per BOE, contributing to a three-year average cost of $ 6.74 per BOE. Financial highlights and consolidated balance sheets for 1998 are included. tabs., figs

  5. Intoxication by star fruit (Averrhoa carambola) in six dialysis patients? (Preliminary report)

    Science.gov (United States)

    Neto, M M; Robl, F; Netto, J C

    1998-03-01

    We observed six cases of patients in a dialysis programme who were apparently intoxicated by ingestion of star fruit. After ingestion of 2-3 fruits or 150-200 ml of the fruit juice, the six patients, who had previously been stable in a regular dialysis programme, developed a variety of symptoms ranging from insomnia and hiccups to agitation, mental confusion and (in one case) death. In preliminary investigations to characterize the hypothetical neurotoxin in the fruit, an extract, when injected intraperitoneally or intracerebroventricularly in rats, provoked persistent convulsions of the tonic-clonic type. It appears that star fruit (Averrhoa carambola) contains an excitatory neurotoxin. Patients with renal failure on conservative or dialysis treatment should be dissuaded from ingestion of the fruit.

    The purpose of this document is to describe a global strategy to integrate the use of space technology in the fight against malaria. Given the well-documented relationship between the vector and its environment, and the ability of existing space technologies to monitor environmental factors, malaria is a strong candidate for the application of space technology. The concept of a malaria early warning system has been proposed in the past' and pilot studies have been conducted. The HI-STAR project (Health Improvement through Space Technologies and Resources) seeks to build on this concept and enhance the space elements of the suggested framework. As such, the mission statement for this International Space University design project has been defined as follows: "Our mission is to develop and promote a global strategy to help combat malaria using space technology". A general overview of malaria, aspects of how space technology can be useful, and an outline of the HI-STAR strategy is presented.

    We explore the effects of active galactic nuclei (AGNs) and star formation activity on the infrared (0.3-1000 {mu}m) spectral energy distributions (SEDs) of luminous infrared galaxies from z = 0.5 to 4.0. We have compiled a large sample of 151 galaxies selected at 24 {mu}m (S {sub 24} {approx}> 100 {mu}Jy) in the GOODS-N and ECDFS fields for which we have deep Spitzer IRS spectroscopy, allowing us to decompose the mid-IR spectrum into contributions from star formation and AGN activity. A significant portion ({approx}25%) of our sample is dominated by an AGN (>50% of the mid-IR luminosity) in the mid-IR. Based on the mid-IR classification, we divide our full sample into four sub-samples: z {approx} 1 star-forming (SF) sources, z {approx} 2 SF sources, AGNs with clear 9.7 {mu}m silicate absorption, and AGNs with featureless mid-IR spectra. From our large spectroscopic sample and wealth of multi-wavelength data, including deep Herschel imaging at 100, 160, 250, 350, and 500 {mu}m, we use 95 galaxies with complete spectral coverage to create a composite SED for each sub-sample. We then fit a two-temperature component modified blackbody to the SEDs. We find that the IR SEDs have similar cold dust temperatures, regardless of the mid-IR power source, but display a marked difference in the warmer dust temperatures. We calculate the average effective temperature of the dust in each sub-sample and find a significant ({approx}20 K) difference between the SF and AGN systems. We compare our composite SEDs to local templates and find that local templates do not accurately reproduce the mid-IR features and dust temperatures of our high-redshift systems. High-redshift IR luminous galaxies contain significantly more cool dust than their local counterparts. We find that a full suite of photometry spanning the IR peak is necessary to accurately account for the dominant dust temperature components in high-redshift IR luminous galaxies.

    We present a study on spectral energy distributions, morphologies, and star formation for an IRAC-selected extremely red object sample in the GOODS Chandra Deep Field-South. This work was enabled by new HST/WFC3 near-IR imaging from the CANDELS survey as well as the deepest available X-ray data from Chandra 4 Ms observations. This sample consists of 133 objects with the 3.6 {mu}m limiting magnitude of [3.6] = 21.5 and is approximately complete for galaxies with M{sub *} > 10{sup 11} M{sub Sun} at 1.5 {<=} z {<=} 2.5. We classify this sample into two types, quiescent and star-forming galaxies (SFGs), in the observed infrared color-color ([3.6]-[24] versus K - [3.6]) diagram. The further morphological study of this sample shows a consistent result with the observed color classification. The classified quiescent galaxies are bulge dominated and SFGs in the sample have disk or irregular morphologies. Our observed infrared color classification is also consistent with the rest-frame color (U - V versus V - J) classification. We also found that quiescent and SFGs are well separated in the nonparametric morphology parameter (Gini versus M{sub 20}) diagram measuring their concentration and clumpiness: quiescent galaxies have a Gini coefficient higher than 0.58 and SFGs have a Gini coefficient lower than 0.58. We argue that the star formation quenching process must lead to or be accompanied by the increasing galaxy concentration. One prominent morphological feature of this sample is that disks are commonly seen in this massive galaxy sample at 1.5 {<=} z {<=} 2.5: 30% of quiescent galaxies and 70% of SFGs with M{sub *} > 10{sup 11} M{sub Sun} have disks in their rest-frame optical morphologies. The prevalence of these extended, relatively undisturbed disks challenges the merging scenario as the main mode of massive galaxy formation.

  18. Selecting appropriate energy efficiency indicators for the Thai Energy Conservation Promotion Programme. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Eichhammer, W.; Gruber, E.; Cremer, C.

    2000-06-01

    In 1992 the Thai Government passed the Energy Conservation Promotion (ECP) Act to improve energy efficiency in Thai industry and commerce. The Thai-German Energy Efficiency Promotion Project (ENEP) is supporting the Department of Energy Development and Promotion (DEDP) in its effort to implement the Energy Conservation Program for large buildings and designated factories. About 4000 buildings and factories under the Compulsory Program, have to report every 6 months their energy consumption data to DEDP. Every 3 years energy audits have to be conducted by registered energy consultants, to identify energy saving opportunities, to set saving targets and to recommend energy conservation measures. Investments in energy efficient technologies are subsidized from an Energy Conservation Fund. Data from the energy consumption reports and the energy audit reports are collected in DEDP's database for further processing. The database is structured according to the Thai Standard Industrial Classification. In order to exploit the wealth of information provided by the auditing procedure the objective of the present work carried out by the consultant FhG-ISI for DEDP/BERC on behalf of the German Gesellschaft fuer Technische Zusammenarbeit (GTZ) was to recommend an appropriate set of energy efficiency indicators. This indicator set should allow DEDP to extract from the energy consumption reports, energy audit reports and other sources, useful statistical information to monitor and improve energy efficiency in Thailand.

    The Federal Government strikes a positive balance of its energy policy. It is an effective policy due to its making use of the capacities of the market, due to its leaving enough room for investors and consumers to make decisions at their own discretion and due to the fact that governmental intervention is limited to cases where it is considered indispensable. Progress in the reduction of dependencies, in energy conservation, international competitive conditions and low-pollution measures are particularly stressed as being positive developments. Emphasize is on topical problems of nuclear energy, the present situation of the energy market, the dominant aims of future energy policy with regard to the market in general and with respect to individual sectors.

    This Winter 2015 edition of the Grenoble Ecole de Management (GEM) Energy Market Barometer gauged the expectations of French energy experts regarding the low oil price and its consequences on alternative energy technologies. The experts were also asked about the investment climate for energy technologies in France. Key findings: - The energy experts consider the current low oil price a temporary phenomenon. The price of a barrel of crude oil (Brent) to reach US$ 55 at the end of the year (2016). About three quarters of respondents expect the price of oil to increase in 5 years and to exceed US$ 100 per barrel within 10 years. - The current weak price of crude oil is thought to have an adverse impact on the amount of investment in renewables for heat generation, in biofuels, and in energy efficiency technologies. - The experts view the current regulatory environment in France for investments in renewables, e-mobility, smart grids and energy efficiency favorably. They expect it to continue to improve over the next 5 years. However, nuclear energy and natural gas will not see their investment climate improved. - The recent developments on the global and national political stage have not moved most energy and CO_2 price expectations. The experts chart a progressive yet under-whelming raise in the price of CO_2 certificates in the medium to long term, from currently 8.5 euro/ton to euro 10-15 euro/ton in 5 years and 20-25 euro/ton in 10 years. - Prices of electricity, oil and natural gas are expected to rise in the medium term but remain stable over the next six months temporary phenomenon. Coal is the only energy carrier for which experts expect a decrease in price over the next five years

    As part of the public-interest mission with which it has been tasked by the public authorities, IFP Energies Nouvelles (IFPEN) focuses on: - providing solutions to take up the challenges facing society in terms of energy and the climate, promoting the emergence of a sustainable energy mix, - creating wealth and jobs by supporting French and European economic activity, and the competitiveness of related industrial sectors. Despite the current economic environment, 2014 was a good year for IFPEN. In the field of renewable energies, major milestones were reached in two significant projects dedicated to the production of second generation biofuels in which IFPEN is very actively involved: processes developed in Futurol TM are already in the pre-marketing phase, while the construction of the two pilot units for the BioTfueL project has just been launched. In the field of ocean energies, IFPEN research has led to the first partnership agreements relating to floating wind turbines anchor technologies and command control systems for wind energy and wave energy conversion. In the transport sector, game-changing concepts are beginning to emerge, such as smart battery charging and a Rankine cycle system for an internal combustion engine transforming combustion heat into energy. In addition, IFPEN have joined forces with innovative SMEs to boost their research in the fields of electric power-trains and power electronics. Finally, IFPEN launched an eco-driving application that has proved extremely popular with the public. Turning now to oil and gas, IFPEN continued to expand its range of basin and reservoir simulation, modeling and characterization software, and it signed several contracts in the field of chemical enhanced recovery solutions with its EOR (Enhanced Oil Recovery) Alliance TM partners. IFPEN also developed new generations of high-performance catalysts and improved the conversion rate of its processes to enable refiners to convert increasingly heavy crudes and

    Phosphatidylcholine transfer protein (PC-TP, also known as StarD2) is a highly specific intracellular lipid binding protein with accentuated expression in oxidative tissues. Here we show that decreased plasma concentrations of glucose and free fatty acids in fasting PC-TP-deficient (Pctp(-/-)) mice are attributable to increased hepatic insulin sensitivity. In hyperinsulinemic-euglycemic clamp studies, Pctp(-/-) mice exhibited profound reductions in hepatic glucose production, gluconeogenesis, glycogenolysis, and glucose cycling. These changes were explained in part by the lack of PC-TP expression in liver per se and in part by marked alterations in body fat composition. Reduced respiratory quotients in Pctp(-/-) mice were indicative of preferential fatty acid utilization for energy production in oxidative tissues. In the setting of decreased hepatic fatty acid synthesis, increased clearance rates of dietary triglycerides and increased hepatic triglyceride production rates reflected higher turnover in Pctp(-/-) mice. Collectively, these data support a key biological role for PC-TP in the regulation of energy substrate utilization.

    This Summer 2015 edition of the Grenoble Ecole de Management (GEM) Energy Market Barometer explored the expectations of French Energy experts regarding the Climate Summit (COP21) in Paris next December, and the future evolution of CO_2 certificate prices. The experts were also asked about the development of energy prices. Key findings: - 62 % of the French energy experts do not expect a legally binding agreement to emerge from the Paris Climate Summit - this share was 77 % among the German experts; - A majority of the French energy experts think that failing to reach a legally binding agreement at the Paris Climate Summit would not change the French climate policy targets; - A legally binding agreement would have positive effects on investment in the energy sector and, in particular, the electrical industry; - Two-thirds of the French energy experts believe that an agreement in Paris would generate a momentum for climate innovation in OECD countries, but less so in non-OECD countries; - CO_2 certificate prices rise only in the medium to long term but levels remain rather low. The announced intention of the G7 to phase out all fossil fuels by the end of this century did not affect the experts' expectations about CO_2 certificate prices or medium-term fuel prices; - Electricity and coal prices are expected to remain stable over the next six months. The majority of the experts consider the current low oil and gas prices to be a rather temporary phenomenon
