    On February 2, 2015 the Offices of High Energy Physics (HEP) and Basic Energy Sciences (BES) convened a Round Table discussion among a group of physicists on ‘Common Problems in Condensed Matter and High Energy Physics’. This was motivated by the realization that both fields deal with quantum many body problems, share many of the same challenges, use quantum field theoretical approaches and have productively interacted in the past. The meeting brought together physicists with intersecting interests to explore recent developments and identify possible areas of collaboration.... Several topics were identified as offering great opportunity for discovery and advancement in both condensed matter physics and particle physics research. These included topological phases of matter, the use of entanglement as a tool to study nontrivial quantum systems in condensed matter and gravity, the gauge-gravity duality, non-Fermi liquids, the interplay of transport and anomalies, and strongly interacting disordered systems. Many of the condensed matter problems are realizable in laboratory experiments, where new methods beyond the usual quasi-particle approximation are needed to explain the observed exotic and anomalous results. Tools and techniques such as lattice gauge theories, numerical simulations of many-body systems, and tensor networks are seen as valuable to both communities and will likely benefit from collaborative development.

    The U.S. Department of Energy’s (DOE) Office of Basic Energy Sciences (BES) supports fundamental research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels to provide the foundations for new energy technologies and to support DOE missions in energy, environment, and national security. The research disciplines covered by BES—condensed matter and materials physics, chemistry, geosciences, and aspects of physical biosciences— are those that discover new materials and design new chemical processes. These disciplines touch virtually every aspect of energy resources, production, conversion, transmission, storage, efficiency, and waste mitigation. BES also plans, constructs, and operates world-class scientific user facilities that provide outstanding capabilities for imaging and spectroscopy, characterizing materials of all kinds ranging from hard metals to fragile biological samples, and studying the chemical transformation of matter. These facilities are used to correlate the microscopic structure of materials with their macroscopic properties and to study chemical processes. Such experiments provide critical insights to electronic, atomic, and molecular configurations, often at ultrasmall length and ultrafast time scales.

    New scientific frontiers, recent advances in theory, and rapid increases in computational capabilities have created compelling opportunities for theory and computation to advance the scientific mission of the Office of Basic Energy Sciences (BES). The prospects for success in the experimental programs of BES will be enhanced by pursuing these opportunities. This report makes the case for an expanded research program in theory and computation in BES. The Subcommittee on Theory and Computation of the Basic Energy Sciences Advisory Committee was charged with identifying current and emerging challenges and opportunities for theoretical research within the scientific mission of BES, paying particular attention to how computing will be employed to enable that research. A primary purpose of the Subcommittee was to identify those investments that are necessary to ensure that theoretical research will have maximum impact in the areas of importance to BES, and to assure that BES researchers will be able to exploit the entire spectrum of computational tools, including leadership class computing facilities. The Subcommittee s Findings and Recommendations are presented in Section VII of this report.

  14. Extraction of the sound velocity from rapidity spectra: Evidence for QGP formation at FAIR/RHIC-BES energies

    International Nuclear Information System (INIS)

    We analyze longitudinal pion spectra from √(sNN)=2 GeV to √(sNN)=20 GeV within Landau's hydrodynamical model and the UrQMD hybrid approach. From the measured data on the widths of the pion rapidity spectra, we extract the sound velocity cs2 in the dense stage of the reactions. It is found that the sound velocity has a local minimum (indicating the softest point in the equation of state, EoS) at √(sNN)=4-9 GeV, an energy range accessible at the Facility for Antiproton and Ion Research (FAIR) as well as the RHIC-Beam Energy Scan (RHIC-BES). This softening of the EoS is compatible with the formation of a QGP at the onset of deconfinement. The extracted sound velocities are then used to calculate an excitation function for the mean transverse mass of pions from the hybrid model. We find that, above √(sNN)∼10 GeV, even the lowest cs2 gives a considerably larger left angle mT right angle of pions compared to data. (orig.)

    2010-04-01

    The nation faces two severe challenges that will determine our prosperity for decades to come: assuring clean, secure, and sustainable energy to power our world, and establishing a new foundation for enduring economic and jobs growth. These challenges are linked: the global demand for clean sustainable energy is an unprecedented economic opportunity for creating jobs and exporting energy technology to the developing and developed world. But achieving the tremendous potential of clean energy technology is not easy. In contrast to traditional fossil fuel-based technologies, clean energy technologies are in their infancy, operating far below their potential, with many scientific and technological challenges to overcome. Industry is ultimately the agent for commercializing clean energy technology and for reestablishing the foundation for our economic and jobs growth. For industry to succeed in these challenges, it must overcome many roadblocks and continuously innovate new generations of renewable, sustainable, and low-carbon energy technologies such as solar energy, carbon sequestration, nuclear energy, electricity delivery and efficiency, solid state lighting, batteries and biofuels. The roadblocks to higher performing clean energy technology are not just challenges of engineering design but are also limited by scientific understanding.Innovation relies on contributions from basic research to bridge major gaps in our understanding of the phenomena that limit efficiency, performance, or lifetime of the materials or chemistries of these sustainable energy technologies. Thus, efforts aimed at understanding the scientific issues behind performance limitations can have a real and immediate impact on cost, reliability, and performance of technology, and ultimately a transformative impact on our economy. With its broad research base and unique scientific user facilities, the DOE Office of Basic Energy Sciences (BES) is ideally positioned to address these needs. BES has laid

    The Lujan Neutron Scattering Center (Lujan Center) at LANSCE is a designated National User Facility for neutron scattering and nuclear physics studies with pulsed beams of moderated neutrons (cold, thermal, and epithermal). As one of five experimental areas at the Los Alamos Neutron Science Center (LANSCE), the Lujan Center hosts engineers, scientists, and students from around the world. The Lujan Center consists of Experimental Room (ER) 1 (ERl) built by the Laboratory in 1977, ER2 built by the Office of Basic Energy Sciences (BES) in 1989, and the Office Building (622) also built by BES in 1989, along with a chem-bio lab, a shop, and other out-buildings. According to a 1996 Memorandum of Agreement (MOA) between the Defense Programs (DP) Office of the National Nuclear Security Agency (NNSA) and the Office of Science (SC, then the Office of Energy Research), the Lujan Center flight paths were transferred from DP to SC, including those in ERI. That MOA was updated in 2001. Under the MOA, NNSA-DP delivers neutron beam to the windows of the target crypt, outside of which BES becomes the 'landlord.' The leveraging nature of the Lujan Center on the LANSCE accelerator is a substantial annual leverage to the $11 M BES operating fund worth approximately $56 M operating cost of the linear accelerator (LINAC)-in beam delivery.

    2011-03-31

    The National Energy Research Scientific Computing Center (NERSC) is the leading scientific computing facility supporting research within the Department of Energy's Office of Science. NERSC provides high-performance computing (HPC) resources to approximately 4,000 researchers working on about 400 projects. In addition to hosting large-scale computing facilities, NERSC provides the support and expertise scientists need to effectively and efficiently use HPC systems. In February 2010, NERSC, DOE's Office of Advanced Scientific Computing Research (ASCR) and DOE's Office of Basic Energy Sciences (BES) held a workshop to characterize HPC requirements for BES research through 2013. The workshop was part of NERSC's legacy of anticipating users future needs and deploying the necessary resources to meet these demands. Workshop participants reached a consensus on several key findings, in addition to achieving the workshop's goal of collecting and characterizing computing requirements. The key requirements for scientists conducting research in BES are: (1) Larger allocations of computational resources; (2) Continued support for standard application software packages; (3) Adequate job turnaround time and throughput; and (4) Guidance and support for using future computer architectures. This report expands upon these key points and presents others. Several 'case studies' are included as significant representative samples of the needs of science teams within BES. Research teams scientific goals, computational methods of solution, current and 2013 computing requirements, and special software and support needs are summarized in these case studies. Also included are researchers strategies for computing in the highly parallel, 'multi-core' environment that is expected to dominate HPC architectures over the next few years. NERSC has strategic plans and initiatives already underway that address key workshop findings. This report includes a

    2016-01-01

    Fluctuations of conserved quantities are sensitive observables to probe the signature of QCD phase transition and critical point in heavy-ion collisions. With the UrQMD model, we have studied the centrality and energy dependence of various order cumulants and cumulant ratios (up to fourth order) of net-proton,net-charge and net-kaon multiplicity distributions in Au+Au collisions at $\\sqrt{s_{NN}}$= 7.7, 11.5, 19.6, 27, 39, 62.4, 200 GeV. The model results show that the production mechanism of the particles and anti-particles have significant impacts on the cumulants of net-particles multiplicity distributions and show strong energy dependence. We also made comparisons between model calculations and experimental data measured in the first phase of the beam energy scan (BES) program by the STAR experiment at RHIC. The comparisons indicate that the baryon conservation effect strongly suppress the cumulants of net-proton distributions at low energies and the non-monotonic energy dependence for the net-proton {\\KV...

    real and immediate impact on cost, reliability, and performance of technology, and ultimately a transformative impact on our economy. With its broad research base and unique scientific user facilities, the DOE Office of Basic Energy Sciences (BES) is ideally positioned to address these needs. BES has laid out a broad view of the basic and grand challenge science needs for the development of future clean energy technologies in a series of comprehensive "Basic Research Needs" workshops and reports (inside front cover and http://www.sc.doe.gov/bes/reports/list.html) and has structured its programs and launched initiatives to address the challenges. The basic science needs of industry, however, are often more narrowly focused on solving specific nearer-term roadblocks to progress in existing and emerging clean energy technologies. To better define these issues and identify specific barriers to progress, the Basic Energy Sciences Advisory Committee (BESAC) sponsored the Workshop on Science for Energy Technology, January 18-21, 2010. A wide cross-section of scientists and engineers from industry, universities, and national laboratories delineated the basic science Priority Research Directions most urgently needed to address the roadblocks and accelerate the innovation of clean energy technologies. These Priority Research Directions address the scientific understanding underlying performance limitations in existing but still immature technologies. Resolving these performance limitations can dramatically improve the commercial penetration of clean energy technologies. A key conclusion of the Workshop is that in addition to the decadal challenges defined in the "Basic Research Needs" reports, specific research directions addressing industry roadblocks are ripe for further emphasis. Another key conclusion is that identifying and focusing on specific scientific challenges and translating the results to industry requires more direct feedback and communication and collaboration

    Trigger efficiencies at BES III were determined for both the J/psi and psi' data taking of 2009. Both dedicated runs and physics datasets are used; efficiencies are presented for Bhabha-scattering events, generic hadronic decay events involving charged tracks, dimuon events and psi' -> pi+pi-J/psi, J/psi -> l+l- events (l an electron or muon). The efficiencies are found to lie well above 99% for all relevant physics cases, thus fulfilling the BES III design specifications.

    2016-01-01

    Fluctuations and correlations of conserved charges are sensitive observables for studying the QCD phase transition and critical point in high-energy heavy-ion collisions. We have studied the centrality and energy dependence of mixed-cumulants (up to fourth order) between net-baryon and net-strangeness in Au+Au collisions at $\\sqrt{s_{NN}}$= 7.7, 11.5, 19.6, 27, 39, 62.4, 200 GeV from UrQMD model. To compare with other theoretical calculations, we normalize these mixed-cumulants by various order cumulants of net-strangeness distributions. We found that the results obtained from UrQMD calculations are comparable with the results from Lattice QCD at low temperature and hadron resonance gas model. The ratios of mixed-cumulants ($R_{11}^{BS},R_{13}^{BS},R_{22}^{BS}$,$R_{31}^{BS}$) from UrQMD calculations show weak centrality dependence. However, the mixed-cumulant ratios $R_{11}^{BS}$ and $R_{31}^{BS}$ show strong increase at low energy, while the $R_{13}^{BS}$ snd $R_{22}^{BS}$ are similar at different energies. ...

    Analysis of directed flow ($v_1$) of protons, antiprotons and pions in heavy-ion collisions is performed in the range of collision energies $\\sqrt{s_{NN}}$ = 2.7--39 GeV. Simulations have been done within a three-fluid model employing a purely hadronic equation of state (EoS) and two versions of the EoS with deconfinement transitions: a first-order phase transition and a smooth crossover transition. The crossover EoS is unambiguously preferable for the description of the most part of experimental data in this energy range. The directed flow indicates that the crossover deconfinement transition takes place in semicentral Au+Au collisions in a wide range of collision energies 4 \\lsim\\sqrt{s_{NN}}\\lsim$ 30 GeV. The obtained results suggest that the deconfinement EoS's in the quark-gluon sector should be stiffer at high baryon densities than those used in the calculation. The latter finding is in agreement with that discussed in astrophysics.

    This report is based on the Department of Energy (DOE) Workshop on “Data and Communications in Basic Energy Sciences: Creating a Pathway for Scientific Discovery” that was held at the Bethesda Marriott in Maryland on October 24-25, 2011. The workshop brought together leading researchers from the Basic Energy Sciences (BES) facilities and Advanced Scientific Computing Research (ASCR). The workshop was co-sponsored by these two Offices to identify opportunities and needs for data analysis, ownership, storage, mining, provenance and data transfer at light sources, neutron sources, microscopy centers and other facilities. Their charge was to identify current and anticipated issues in the acquisition, analysis, communication and storage of experimental data that could impact the progress of scientific discovery, ascertain what knowledge, methods and tools are needed to mitigate present and projected shortcomings and to create the foundation for information exchanges and collaboration between ASCR and BES supported researchers and facilities. The workshop was organized in the context of the impending data tsunami that will be produced by DOE’s BES facilities. Current facilities, like SLAC National Accelerator Laboratory’s Linac Coherent Light Source, can produce up to 18 terabytes (TB) per day, while upgraded detectors at Lawrence Berkeley National Laboratory’s Advanced Light Source will generate ~10TB per hour. The expectation is that these rates will increase by over an order of magnitude in the coming decade. The urgency to develop new strategies and methods in order to stay ahead of this deluge and extract the most science from these facilities was recognized by all. The four focus areas addressed in this workshop were: Workflow Management - Experiment to Science: Identifying and managing the data path from experiment to publication. Theory and Algorithms: Recognizing the need for new tools for computation at scale, supporting large data sets and realistic

  20. Offline Computing and Communications in the Bes Collaboration

    Science.gov (United States)

    Lou, Xinchou

    Unlike other major High Energy physics experiments, the BES experiment, centered at the Institute of High Energy Physics in Beijing, China, has lacked funds to purchase or lease mainframe systems such as IBM and CRAY to facilitate the experiment's needs for event reconstruction and Monte Carlo simulation. A distributed, RISC-processor based Unix computing system and data farm provides natural solution to BES's long standing problem of shortage in computing power. A new Unix system has been built at IHEP in China for offline reconstruction. Several Unix sites haven been developed in the US, some of which maintain specific sets of data and provide the collaboration with access to them. Codes and constants are managed by the CODEMAN code management system simultaneously at all sites. Software tools have been developed to aid in batch operation and tape handling. BES has improved its internal communication among physicists with video teleconference technology and the World Wide Web. The steady improvement in computing, data handling and communications in BES have enabled the collaboration to study a broad spectrum of physics topics recently.

    potentially revolutionary science involves soft excitations such as magnons and phonons; in general, these are well below the resolution that can be probed by today’s optical systems. The study of these low-energy excitations will only move forward if advances are made in high-resolution gratings for the soft X-ray energy region, and higher-resolution crystal analyzers for the hard X-ray region. In almost all the forefront areas of X-ray science today, the main limitation is our ability to focus, monochromate, and manipulate X-rays at the level required for these advanced measurements. To address these issues, the U.S. Department of Energy (DOE) Office of Basic Energy Sciences (BES) sponsored a workshop, X-ray Optics for BES Light Source Facilities, which was held March 27–29, 2013, near Washington, D.C. The workshop addressed a wide range of technical and organizational issues. Eleven working groups were formed in advance of the meeting and sought over several months to define the most pressing problems and emerging opportunities and to propose the best routes forward for a focused R&D program to solve these problems. The workshop participants identified eight principal research directions (PRDs), as follows: Development of advanced grating lithography and manufacturing for high-energy resolution techniques such as soft X-ray inelastic scattering. Development of higher-precision mirrors for brightness preservation through the use of advanced metrology in manufacturing, improvements in manufacturing techniques, and in mechanical mounting and cooling. Development of higher-accuracy optical metrology that can be used in manufacturing, verification, and testing of optomechanical systems, as well as at wavelength metrology that can be used for quantification of individual optics and alignment and testing of beamlines. Development of an integrated optical modeling and design framework that is designed and maintained specifically for X-ray optics. Development of

  8. A report of the Basic Energy Sciences Advisory Committee: 1992 review of the Basic Energy Sciences Program of the Department of Energy

    International Nuclear Information System (INIS)

    The general quality of BES research at each of the 4 laboratories is high. Diversity of management at the different laboratories is beneficial as long as the primary BES mission and goals are clearly identified and effectively pursued. External sources of personnel should be encouraged. DOE has been designing a new high flux research reactor, the Advanced Neutron Source, to replace DOE's two aging research reactors; BESAC conducted a panel evaluation of neutron sources for the future. The two new light sources, Advanced Light Source and Advanced Photon source will come on line well before all of their beamline instrumentation can be funded, developed, and installed. Appointment of a permanent director and deputy for OBES would enhance OBES effectiveness in budget planning and intra-DOE program coordination. Some DOE and DP laboratories have substantial infrastructure which match well industry development-applications needs; interlaboratory partnerships in this area are encouraged. Funding for basic science research programs should be maintained at FY1993 levels, adjusted for inflation; OBES plans should be updated and monitored to maintain the balance between basic research and facilities construction and operation. The recommendations are discussed in detail in this document

    2009-08-13

    The U.S. Department of Energy’s (DOE) Office of Basic Energy Sciences (BES) and Office of Advanced Scientific Computing Research (ASCR) workshop in August 2009 on extreme-scale computing provided a forum for more than 130 researchers to explore the needs and opportunities that will arise due to expected dramatic advances in computing power over the next decade. This scientific community firmly believes that the development of advanced theoretical tools within chemistry, physics, and materials science—combined with the development of efficient computational techniques and algorithms—has the potential to revolutionize the discovery process for materials and molecules with desirable properties. Doing so is necessary to meet the energy and environmental challenges of the 21st century as described in various DOE BES Basic Research Needs reports. Furthermore, computational modeling and simulation are a crucial complement to experimental studies, particularly when quantum mechanical processes controlling energy production, transformations, and storage are not directly observable and/or controllable. Many processes related to the Earth’s climate and subsurface need better modeling capabilities at the molecular level, which will be enabled by extreme-scale computing.

    International Nuclear Information System (INIS)

    The author avails himself of the by now controversial jurisdiction on partial licences issued for nuclear power plants to argue relevant provisions of the Basic Law and to include facts which are related to the Basic Law. This is also necessary for reasons of social policy, since such a juridicial decision produces an effect which spreads far beyond the litigants. In a constitutional state that has to stand the test in the conflict arising between human rights and technical progress, the controversy on basic rights has to form a part of the trial and of the opinion. There are two sides to the rule of law: The citizen's obligation not to use violence, and his right to be strictly protected by the Basic Law. (HSCH)

    2011-06-15

    In June 2010, the Japanese cabinet adopted a new Basic Energy Plan (BEP). This was the third such plan that the government has approved since the passage of the Basic Act on Energy Policy in 2002, and it represents the most significant statement of Japanese energy policy in more than four years, since the publication of the New National Energy Strategy (NNES) in 2006. Perhaps more than its predecessors, moreover, the new plan establishes a number of ambitious targets as well as more detailed measures for achieving those targets. Among the targets are a doubling of Japan's 'energy independence ratio,' a doubling of the percentage of electricity generated by renewable sources and nuclear power, and a 30 percent reduction in energy-related CO{sub 2} emissions, all by 2030. This paper explains the origins of the 2010 BEP and why it was adopted. It then describes the content of the plan and how it differs from the NNES. A third section analyzes the appropriateness of the new goals and targets contained in the BEP and their feasibility, finding that achievement of many of the targets was likely to be quite challenging even before the March 2011 earthquake, tsunami, and nuclear crisis. - Highlights: > Origins of Japan's new Basic Energy Plan. > Content of Japan's new Basic Energy Plan. > Feasibility of achieving the targets in Japan's new Basic Energy Plan. > Impact of 2011 earthquake and tsunami on Japanese energy policy.

    Over the past quarter century, light-source user facilities have transformed research in areas ranging from gas-phase chemical dynamics to materials characterization. The ever-improving capabilities of these facilities have revolutionized our ability to study the electronic structure and dynamics of atoms, molecules, and even the most complex new materials, to understand catalytic reactions, to visualize magnetic domains, and to solve protein structures. Yet these outstanding facilities still have limitations well understood by their thousands of users. Accordingly, over the past several years, many proposals and conceptual designs for"next-generation" x-ray light sources have been developed around the world. In order to survey the scientific problems that might be addressed specifically by those new light sources operating below a photon energy of about 3 keV and to identify the scientific requirements that should drive the design of such facilities, a workshop"Science for a New Class of Soft X-Ray Light Sources" was held in Berkeley in October 2007. From an analysisof the most compelling scientific questions that could be identified and the experimental requirements for answering them, we set out to define, without regard to the specific technologies upon which they might be based, the capabilities such light sources would have to deliver in order to dramatically advance the state of research in the areas represented in the programs of the Department of Energy's Office of Basic Energy Sciences (BES). This report is based on the workshop presentations and discussions.

Moreover, the STAR experimental transverse-momentum distributions of negatively charged particles, produced in Au-Au collisions at RHIC BES energies, are approximately described by the two-component Erlang distribution and the single Tsallis statistics. The excitation functions of free parameters are obtained from the fit to the experimental data. A weak softest point in the string tension in Ω hyperon spectra is observed at 7.7 GeV. (orig.)

    2001-07-01

    This is the final report of a research programme that covered the need for long-term basic research in Norway within the main fields of new renewable energy sources and hydroelectric power. For the hydropower part, emphasis was placed on the environmental consequences and several projects have been done, with different approaches. Other aspects of hydropower have also been supported, such as dam safety and flow in water paths connected to turbines. Within the field of renewable energies, priority was given to solar energy and bio energy. Research on hydrogen as an energy carrier has also been supported; the programme mainly targeted universities and the research institutes, and the education of PhD's has been a priority. The programme was funded through the Ministry of Petroleum and Energy and the budget was 33 million NOK for the period 1997 - 2000.

  14. Basic ingredients of free energy calculations: a review.

    Science.gov (United States)

    Christ, Clara D; Mark, Alan E; van Gunsteren, Wilfred F

    2010-06-01

    Methods to compute free energy differences between different states of a molecular system are reviewed with the aim of identifying their basic ingredients and their utility when applied in practice to biomolecular systems. A free energy calculation is comprised of three basic components: (i) a suitable model or Hamiltonian, (ii) a sampling protocol with which one can generate a representative ensemble of molecular configurations, and (iii) an estimator of the free energy difference itself. Alternative sampling protocols can be distinguished according to whether one or more states are to be sampled. In cases where only a single state is considered, six alternative techniques could be distinguished: (i) changing the dynamics, (ii) deforming the energy surface, (iii) extending the dimensionality, (iv) perturbing the forces, (v) reducing the number of degrees of freedom, and (vi) multi-copy approaches. In cases where multiple states are to be sampled, the three primary techniques are staging, importance sampling, and adiabatic decoupling. Estimators of the free energy can be classified as global methods that either count the number of times a given state is sampled or use energy differences. Or, they can be classified as local methods that either make use of the force or are based on transition probabilities. Finally, this overview of the available techniques and how they can be best used in a practical context is aimed at helping the reader choose the most appropriate combination of approaches for the biomolecular system, Hamiltonian and free energy difference of interest.

  15. Basic Solar Energy Research in Japan (2011 EFRC Forum)

    International Nuclear Information System (INIS)

    Kazunari Domen, Chemical System Engineering Professor at the University of Tokyo, was the second speaker in the May 26, 2011 EFRC Forum session, 'Global Perspectives on Frontiers in Energy Research.' In his presentation, Professor Domen talked about basic solar energy research in Japan. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss 'Science for our Nation's Energy Future.' In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several 'grand challenges' and use-inspired 'basic research needs' recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

  16. Basic plan of development and utilization of atomic energy, 1980

    International Nuclear Information System (INIS)

    The stable acquisition of energy is indispensable for the maintenance and improvement of national living standard and the development of social economy. The supply of oil tends to be tight in medium and long term perspective. Japan must acquire oil stably, save oil consumption as far as possible, and develop substitute energy. The development and utilization of atomic energy must be promoted as the most important subject in the energy policy because it is the most promising substitute energy. The nuclear power stations in operation in Japan are 21 plants with 15 million kW capacity, and it is equivalent to 12% of the total power generation. Adding the plants under construction and in preparation, the total becomes 35 plants and 28 million kW, but the construction is behind schedule due to the difficulty in the location of new power stations. As for the research and development on atomic energy, the establishment of nuclear fuel cycle such as the enrichment of uranium, the reprocessing of fuel and the treatment and disposal of radioactive wastes, the development of power reactors of new types, the research on nuclear fusion and so on have been endeavored. The maintenance of health of people and the preservation of environment are the prerequisities to the promotion of atomic energy. Japan contributes to form the new order on the basis of the results of INFCE. The development and utilization of atomic energy in 1980 are forwarded based on the basic policy described. (Kako, I.)

  17. Basic research needs to assure a secure energy future. A report from the Basic Energy Sciences Advisory Committee

    2003-02-01

    This report has highlighted many of the possible fundamental research areas that will help our country avoid a future energy crisis. The report may not have adequately captured the atmosphere of concern that permeated the discussions at the workshop. The difficulties facing our nation and the world in meeting our energy needs over the next several decades are very challenging. It was generally felt that traditional solutions and approaches will not solve the total energy problem. Knowledge that does not exist must be obtained to address both the quantity of energy needed to increase the standard of living world-wide and the quality of energy generation needed to preserve the environment. In terms of investments, it was clear that there is no single research area that will secure the future energy supply. A diverse range of economic energy sources will be required--and a broad range of fundamental research is needed to enable these. Many of the issues fall into the traditional materials and chemical sciences research areas, but with specific emphasis on understanding mechanisms, energy related phenomena, and pursuing novel directions in, for example, nanoscience and integrated modeling. An important result from the discussions, which is hopefully apparent from the brief presentations above, is that the problems that must be dealt with are truly multidisciplinary. This means that they require the participation of investigators with different skill sets. Basic science skills have to be complemented by awareness of the overall nature of the problem in a national and world context, and with knowledge of the engineering, design, and control issues in any eventual solution. It is necessary to find ways in which this can be done while still preserving the ability to do first-class basic science. The traditional structure of research, with specific disciplinary groupings, will not be sufficient. This presents great challenges and opportunities for the funders of the

    Highlights: • We integrated a fluctuation beam emission measurement into the ITER CXRS prototype spectrometer. • The fluctuation BES measurement provided data at TEXTOR that agree well with the simulation based on the Simulation Of Spectra package. • The same simulation method has been used to evaluate the feasibility of a fluctuation BES measurement on the ITER DNB using the CXRS periscopes. -- Abstract: The ITER core CXRS diagnostic system collects the light emitted from the interaction of the diagnostic neutral beam with the core plasma and guides it via a mirror labyrinth through the upper port plug no. 3 towards a fiber bundle, which then transmits the light into a set of spectrometers for spectral analysis. In order to test the accessibility of the special parameter range required for the ITER measurement, a prototype spectrometer was built and operated successfully at the TEXTOR tokamak. In addition to the He/Be, C/Ne and H/D/T regular spectral channels, a fluctuation beam emission spectroscopy (BES) system has been integrated to measure core MHD activity, and validate corresponding ITER simulation results. The fluctuation system can be operated as an alternative to the spectral BES measurement, and has 8 spatial channels sampled at 2 MHz. In this paper, we present details of the fluctuation BES system and its interface to the ITER prototype spectrometer along with simulation and measurement results at TEXTOR. We show that the measurement fully confirms the simulation results on achievable photon current at the detector and on the signal to noise ratio.

    1978-08-01

    The larger field covered in the workshop consists of (1) synthesis and characterization, (2) physical chemistry, (3) physics, and (4) engineering. Polymeric materials are properly regarded as new materials in their own right, not as replacements for existing materials. As such they need to be studied to understand the properties which are unique to them by virtue of their particular molecular structures. Technological applications will rationally follow from such studies. It is the objective of this report to point out basic research needs in polymer materials related to energy. The development of sophisticated instrumentation makes the task of molecular characterization possible on a level hitherto unattainable. Many of these instruments because of their size and complexity must of necessity be located at the DOE National Laboratories. The importance of personnel trained in the polymer field located at these facilities is emphasized. In the past there has been relatively little concerted polymer research within the energy community. This report attempts to describe the present situation and point out some needs and future research directions. (GHT)

    The Engineering Research Program, a component program of the DOE Office of Basic Energy Sciences (BES), was established in 1979 to aid in resolving the numerous engineering issues arising from efforts to meet U.S. energy needs. The major product of the program became part of the body of knowledge and data upon which the applied energy technologies are founded; the product is knowledge relevant to energy exploration, production, conversion and use.

  4. Data Management and its Role in Delivering Science at DOE BES User Facilities - Past, Present, and Future

    International Nuclear Information System (INIS)

    The primary mission of user facilities operated by Basic Energy Sciences under the Department of Energy is to produce data for users in support of open science and basic research. We trace back almost 30 years of history across selected user facilities illustrating the evolution of facility data management practices and how these practices have related to performing scientific research. The facilities cover multiple techniques such as X-ray and neutron scattering, imaging and tomography sciences. Over time, detector and data acquisition technologies have dramatically increased the ability to produce prolific volumes of data challenging the traditional paradigm of users taking data home upon completion of their experiments to process and publish their results. During this time, computing capacity has also increased dramatically, though the size of the data has grown significantly faster than the capacity of one's laptop to manage and process this new facility produced data. Trends indicate that this will continue to be the case for yet some time. Thus users face a quandary for how to manage today's data complexity and size as these may exceed the computing resources users have available to themselves. This same quandary can also stifle collaboration and sharing. Realizing this, some facilities are already providing web portal access to data and computing thereby providing users access to resources they need. Portal based computing is now driving researchers to think about how to use the data collected at multiple facilities in an integrated way to perform their research, and also how to collaborate and share data. In the future, inter-facility data management systems will enable next tier cross-instrument-cross facility scientific research fuelled by smart applications residing upon user computer resources. We can learn from the medical imaging community that has been working since the early 1990's to integrate data from across multiple modalities to achieve better

    2014-11-01

    Reductive removal of nitrate in bioelectrochemical system (BES) at abiotic cathode, biocathode and biohydrogen facilitated biocathode were investigated. It was found that nitrate removal efficiency reached 95% and 59% at the biohydrogen facilitated biocathode and biocathode respectively, while which was only 13% at the abiotic cathode. Meanwhile, activity of nitrate reductase reached 0.701 g-N/Lh for the biohydrogen facilitated group, which was about 9.3 times of the biocathode group. Moreover, electrochemical performances as power density, ohmic resistance, and polarization resistance of the biohydrogen facilitated group reached 76.96 mW/m(3), 8.63 ohm and 383 ohm, respectively, which were better than two other groups. Finally, an obvious shift of bacterial community responsible for the enhanced nitrate reduction between the two biocathode groups was observed. Therefore, nitrate reduction in BES could be enhanced at the biocathode than that of the abiotic cathode, and then be further boosted with the combination of biohydrogen.

    The global utilization of nuclear energy has come a long way from its humble beginnings in the first sustained nuclear reaction at the University of Chicago in 1942. Today, there are over 440 nuclear reactors in 31 countries producing approximately 16% of the electrical energy used worldwide. In the United States, 104 nuclear reactors currently provide 19% of electrical energy used nationally. The International Atomic Energy Agency projects significant growth in the utilization of nuclear power over the next several decades due to increasing demand for energy and environmental concerns related to emissions from fossil plants. There are 28 new nuclear plants currently under construction including 10 in China, 8 in India, and 4 in Russia. In the United States, there have been notifications to the Nuclear Regulatory Commission of intentions to apply for combined construction and operating licenses for 27 new units over the next decade. The projected growth in nuclear power has focused increasing attention on issues related to the permanent disposal of nuclear waste, the proliferation of nuclear weapons technologies and materials, and the sustainability of a once-through nuclear fuel cycle. In addition, the effective utilization of nuclear power will require continued improvements in nuclear technology, particularly related to safety and efficiency. In all of these areas, the performance of materials and chemical processes under extreme conditions is a limiting factor. The related basic research challenges represent some of the most demanding tests of our fundamental understanding of materials science and chemistry, and they provide significant opportunities for advancing basic science with broad impacts for nuclear reactor materials, fuels, waste forms, and separations techniques. Of particular importance is the role that new nanoscale characterization and computational tools can play in addressing these challenges. These tools, which include DOE synchrotron X

    In terms of the hadron-string-dynamics (HSD) approach we investigate the correlation function in the azimuthal angle $\\psi$ of charged hadrons that is expected to be sensitive to a signal of local strong parity violation. Our analysis of Au+Au collisions is based on the recent STAR data within the RHIC Beam-Energy-Scan (BES) program. The HSD model reasonably reproduces STAR data for $\\sqrt{s_{NN}}=$7.7 GeV, while there are some deviations from the experiment at the collision energy of 11.5 GeV and an increase of deviations between theory and experiment at $\\sqrt{s_{NN}}=$39 GeV. For reference, the results for $\\sqrt{s_{NN}}=$ 200 GeV are given as well. The role of the retarded electromagnetic field is discussed and a compensation effect for the action of its electric and magnetic components is pointed out. We conclude that the recent RHIC BES data at $\\sqrt{s_{NN}}=$7.7 and 11.5 GeV can be understood on the hadronic level without involving the idea of a strong parity violation; however, at $\\sqrt{s_{NN}}\\sim$...

    World demand for energy is projected to more than double by 2050 and to more than triple by the end of the century. Incremental improvements in existing energy networks will not be adequate to supply this demand in a sustainable way. Finding sufficient supplies of clean energy for the future is one of society?s most daunting challenges. Sunlight provides by far the largest of all carbon-neutral energy sources. More energy from sunlight strikes the Earth in one hour (4.3 ? 1020 J) than all the energy consumed on the planet in a year (4.1 ? 1020 J). We currently exploit this solar resource through solar electricity ? a $7.5 billion industry growing at a rate of 35?40% per annum ? and solar-derived fuel from biomass, which provides the primary energy source for over a billion people. Yet, in 2001, solar electricity provided less than 0.1% of the world's electricity, and solar fuel from modern (sustainable) biomass provided less than 1.5% of the world's energy. The huge gap between our present use of solar energy and its enormous undeveloped potential defines a grand challenge in energy research. Sunlight is a compelling solution to our need for clean, abundant sources of energy in the future. It is readily available, secure from geopolitical tension, and poses no threat to our environment through pollution or to our climate through greenhouse gases. This report of the Basic Energy Sciences Workshop on Solar Energy Utilization identifies the key scientific challenges and research directions that will enable efficient and economic use of the solar resource to provide a significant fraction of global primary energy by the mid 21st century.

  13. Self-similarity of hard cumulative processes in fixed target experiment for BES-II at STAR

    International Nuclear Information System (INIS)

    Search for signatures of phase transition in Au + Au collisions is in the heart of the heavy ion program at RHIC. Systematic study of particle production over a wide range of collision energy revealed new phenomena such as the nuclear suppression effect expressed by nuclear modification factor, the constituent quark number scaling for elliptic flow, the 'ridge effect' in - fluctuations, etc. To determine the phase boundaries and location of the critical point of nuclear matter, the Beam Energy Scan (BES-I) program at RHIC has been suggested and performed by STAR and PHENIX Collaborations. The obtained results have shown that the program (BES-II) should be continued. In this paper a proposal to use hard cumulative processes in BES Phase-II program is outlined. Selection of the cumulative events is assumed to enrich data sample by a new type of collisions characterized by higher energy density and more compressed matter. This would allow finding clearer signatures of phase transition, location of a critical point and studying extreme conditions in heavy ion collisions.

    2007-09-01

    GLoBES (General Long Baseline Experiment Simulator) is a flexible software package to simulate neutrino oscillation long baseline and reactor experiments. On the one hand, it contains a comprehensive abstract experiment definition language (AEDL), which allows to describe most classes of long baseline experiments at an abstract level. On the other hand, it provides a C-library to process the experiment information in order to obtain oscillation probabilities, rate vectors, and Δχ-values. Currently, GLoBES is available for GNU/Linux. Since the source code is included, the port to other operating systems is in principle possible. GLoBES is an open source code that has previously been described in Computer Physics Communications 167 (2005) 195 and in Ref. [7]). The source code and a comprehensive User Manual for GLoBES v3.0.8 is now available from the CPC Program Library as described in the Program Summary below.

    M.R.C. Greenwood brought out some things about the importance of making sure that the public, who funds our work, knows that there is value to it. Currently, the Basic Energy Sciences (BES) advisory committee has a panel that is doing just that for BES research. I insisted that this panel not be the same folks. It is chaired by an economist and it has several nontechnical members on it. I wanted them to have some, you might say, people off the street on it. I have some confidence that often when you bring things to the people, you get good decisions.

  20. Basic research with low-energy accelerator systems

    International Nuclear Information System (INIS)

    The major important tasks of basic research are to push back the frontiers of scientific knowledge, and to train students. It will be shown that small accelerator facilities are still capable of producing interesting and exciting results that are on the leading edge of scientific inquiry. In addition, I will argue that, although these facilities often cannot afford to train students in the use of the most modern research equipment, there is an important compensating benefit in that they larger facilities. This 'liberal' education, as opposed to 'technical' instruction in the use of the most modern research equipment, may well be of more value to society in the long run. (Author)

    The present book was written to address the needs of those readers interested in wind energy converters. The authors have tried to strike a balance between a short book chapter and a very detailed book for experts in the field. There were three prime reasons behind doing so: first, the field is highly interdisciplinary and requires a more accessible format for non-experts. The second reason for this more compact version is that both authors have encountered many students and technically oriented people who were searching for this type of book on wind energy. The third reason and motivation for

    Full Text Available It has not yet been elucidated whether the observed flux suppression for ultra-high energy cosmic rays (UHECR at energies above ≃ 4 x 1019 eV is a signature of the Greisen-Zatsepin-Kuzmin (GZK cutoff or a consequence of other phenomena. In both cases, violations of the standard fundamental principles of Physics can be present and play a significant role. They can in particular modify cosmic-ray interactions, propagation or acceleration at very high energy. Thus, in a long-term program, UHECR data can hopefully be used to test relativity, quantum mechanics, energy and momentum conservation, vacuum properties... as well as the elementariness of standard particles. Data on cosmic rays at energies ≃ 1020 eV may also be sensitive to new physics generated well beyond Planck scale. A typical example is provided by the search for possible signatures of a Lorentz symmetry violation (LSV associated to a privileged local reference frame (the "vacuum rest frame", VRF. If a VRF exists, the internal structure of standard particles at ultra-high energy can undergo substantial modifications. Similarly, the conventional particle symmetries may cease to be valid at such energies instead of heading to a grand unification and the structure of vacuum may no longer be governed by standard quantum field theory. Then, the question whether the notion of Planck scale still makes sense clearly becomes relevant and the very grounds of Cosmology can undergo essential modifications. UHECR studies naturally interact with the interpretation of WMAP and Planck observations. Recent Planck data analyses tend to confirm the possible existence of a privileged space direction. If the observed phenomenon turns out to be a signature of the spinorial space-time (SST we suggested in 1996-97, then conventional Particle Physics may correspond to the local properties of standard matter at low enough energy and large enough distances. This would clearly strengthen the cosmological

    2014-03-01

    During the operations of the new generation Beijing Electron and Positron Collider (BEPC II) and the Beijing Spectrometer (BES III), the inner surface of the beam pipe is subjected to high radiation heat loads. Continuous high temperatures or large temperature fluctuations can cause the main drift chamber (MDC) to detect particles abnormally. Hence, a beam pipe with a cooling system was designed, and temperature fields across the beam pipe and the MDC inner cylinder were studied experimentally and by finite-element simulations. When the inlet temperatures of the cooling oil and cooling water for the central and extended beam pipes were set to 291.4 K and 291.6 K, respectively, results showed that the inner surface temperature of the MDC inner cylinder can be controlled within the range of 292.8-293.9 K for various powers of radiation heat. This range satisfies the operating requirements of 293±2 K.

  12. Energy from biomass — Some basic physical and related considerations

    Science.gov (United States)

    Gloyne, R. W.

    1983-09-01

    The production of vegetable matter (biomass) by photosynthesis is determined by species and by meteorological factors (especially, but not exclusively, solar radiation). Annual net primary production of land-based biomass corresponds to only about 1/1000 of the intercepted irradiation at ground level, but even so, is 10 times the world's estimated energy needs. The exploitation of this energy potential at any one place is critically influenced by the economic, political and social factors, amongst which are the competition from agriculture (especially food crops), forestry, industrial and urban (including leisure) needs for land and resources. Social factors (e.g. population and population density) also constitute prime influences. Strategies for utilisation range from the cultivation of special energy crops (readily conceivable on the American/ Australasian continents); to the more efficient manipulation of current land-use patterns (including “opportunity” cropping); to the more effective exploitation of biologi cal wastes (e.g. methane from sewage), probably the only immediately practical possibility in any densely populated and highly industrialised country. The spatial pattern of solar irradiation at ground level is complex. In the summer, total daily irradiation in continental high latitudes can exceed that in maritime temperate regions; and this combined with species differences and the almost infinite variety of shape and orientation of plant parts, result in a photosynthetic production of biomass which does not conform completely to a zonal pattern, but in broad terms annual dry matter production varies from a few kg/ha in Arctic Tundra to tens of tonnes in temperate latitudes rising to nearly 100 t/ha for perennial tropical crops. If a species could be developed to grow throughout the year at the current seasonal rate, a yield of 150 t/yr, ha) seems possible.

    2007-07-01

    The combination of sites and technologies to so-called renewable energy portfolios, which are being developed and implemented under the same financing umbrella, is currently the subject of intense discussion in the finance world. The resulting portfolio effect may allow the prediction of a higher return with the same risk or the same return with a lower risk - always in comparison with the investment in a single project. Models are currently being developed to analyse this subject and derive the portfolio effect. In particular, the effect of the spatial distribution, as well as the effects of using different technologies, suppliers and cost assumptions with different level of uncertainties, are of importance. Wind parks, photovoltaic, biomass, biogas and hydropower are being considered. The status of the model development and first results are being presented in the current paper. In a first example, the portfolio effect has been calculated and analysed using selected parameters for a wind energy portfolio of 39 sites distributed over Europe. Consequently it has been shown that the predicted yield, with the predetermined probabilities between 75 to 90%, is 3 - 8% higher than the sum of the yields for the individual wind parks using the same probabilities.

    Analyzing the chemical industry's energy use is challenging because of the sector's complexity and the prevailing uncertainty in energy use and production data. We develop an advanced bottom-up model (PIE-Plus) which encompasses the energy use of the 139 most important chemical processes. We apply this model in a case study to analyze the German basic chemical industry's energy use and energy efficiency improvements in the period between 1995 and 2008. We compare our results with data from the German Energy Balances and with data published by the International Energy Agency (IEA). We find that our model covers 88% of the basic chemical industry's total final energy use (including non-energy use) as reported in the German Energy Balances. The observed energy efficiency improvements range between 2.2 and 3.5% per year, i.e., they are on the higher side of the values typically reported in literature. Our results point to uncertainties in the basic chemical industry's final energy use as reported in the energy statistics and the specific energy consumption values. More efforts are required to improve the quality of the national and international energy statistics to make them usable for reliable monitoring of energy efficiency improvements of the chemical industry.

    International Nuclear Information System (INIS)

    The fourth Energy Basic Plan prepared mainly by the Ministry of Economy, Trade and Industry (METI) is the first plan after Fukushima Nuclear Accident. In this plan, the challenges and the directions of energy policy are discussed considering the mid- and long-term energy demand structure, especially 2018-2020 as the period of intensive reform. However, the energy mix indicates the composition of electrical sources and so on is not included due to the uncertainty about the prospect in the restart of nuclear power plant and the introduction of renewable energy sources. This article discusses the issues in the energy demand structure in Japan indicated in this plan, the principles in energy policy, as well as the perspectives for reform. These are summarized in three categories of (1) primary energy sources, (2) secondary energy supply, and (3) cross-sectional main subjects, particularly focusing on the viewpoints described in the chapter 2 and later.

    2015-01-01

    Full Text Available This article explores the symbolic image of the “window” in Fyodor Sologub’s novel The Petty Demon (Melky bes, with a particular focus on the connections between literature, semiotics, and psychopathology. Windows can be thought of as thin and transparent frameworks which divide the external world (“the others” from the internal one (“the self”, but, at the same time, they allow interactions between the two as well. Peaceful interactions are seldom contemplated; in most cases, the individual ego clashes with the collectivity. This is what happens in Sologub’s Petty Demon. Here, windows represent the struggle of the novel’s anti-hero Peredonov against the world; they stand as a symbol of his alienation from Russian society and life. Windows appear several times in the novel to signify Peredonov’s troublesome relationship with other people. In particular, broken windows and glasses suggest a growing gap between “the self” and “the others”, Peredonov and reality. Imagery drawn from the visual field helps the author to describe the protagonist’s fall into madness. On one hand, Peredonov sees the world through his paranoid eyes, and considers “the others” as a threat to his own identity. Even though, on the other hand, it is Peredonov himself, who suffering from persecution mania, fears that he is spied on by enemies. At the end, alterity will triumph over him. Thus, the novel also portrays Peredonov’s tragedy: the loss of his own “self”.

    2012-01-01

    Impacts: The BES program supports basic research that underpins a broad range of energy technologies. Research in materials sciences and engineering leads to the development of materials that improve the efficiency, economy, environmental acceptability, and safety of energy generation, conversion, transmission, storage, and use. For example, advances in superconductivity have been introduced commercially in a number of demonstration projects around the country. Improvements in alloy design for high temperature applications are used in commercial furnaces and in green technologies such as lead-free solder. Research in chemistry has led to advances such as efficient combustion systems with reduced emissions of pollutants; new solar photoconversion processes; improved catalysts for the production of fuels and chemicals; and better separations and analytical methods for applications in energy processes, environmental remediation, and waste management. Research in geosciences results in advanced monitoring and measurement techniques for reservoir definition and an understanding of the fluid dynamics of complex fluids through porous and fractured subsurface rock. Research in the molecular and biochemical nature of photosynthesis aids the development of solar photo-energy conversion. The BES program also plays a major role in enabling the nanoscale revolution. The importance of nanoscience to future energy technologies is clearly reflected by the fact that all of the elementary steps of energy conversion (e.g., charge transfer, molecular rearrangement, and chemical reactions) take place on the nanoscale. The development of new nanoscale materials, as well as the methods to characterize, manipulate, and assemble them, create an entirely new paradigm for developing new and revolutionary energy technologies.

    2009-01-01

    The electronic and the optical properties of the cubic zinc-blende(ZB)BeS under high pressure have been in-vestigated by using ab inztio plane-wave pseudopotential density functional theory method in the generalised gradient approximation(GGA)for exchange-correlation interaction. The electronic band structure and the pressure dependence of the total and partial densities of state under pressure are successfully described. Our calculations show that the ZB BeS has large and indirect band gaps associated with(Γ→X)transitions in ambient conditions. The results obtained are consistent with the experimental data available and other calculations. The optical properties, including dielectric function, energy-loss function, complex refractive index, reflection and absorption spectra, are investigated and analysed at different external pressures. The results suggest that the optical absorption appears moctly in the ultra-violet region and the curve of refractive index shift toward high energies(blue shift)with pressure increasing.

  7. Equatorial Energy Accumulation and Emanation Regions: Impacts of a Zonally Varying Basic State.

    Science.gov (United States)

    Webster, Peter J.; Chang, Hai-Ru

    1988-03-01

    Previous studies have suggested that the regions of mean anomalous perturbation kinetic energy which exist in the vicinity of the equatorial upper-tropospheric westerlies are the result of the propagation of extratropical synoptic and low frequency waves through the equatorial `westerly duet' where a subsequent wave energy convergence occurs. The proposition that these perturbed equatorial regions may arise from remote equatorial energy sources is investigated. It is shown that three criteria must be met. The first two, the existence of wave energy sources along the equator and a mechanism to transport that energy longitudinally, are accounted for relatively easily with existing theory of divergent, trapped equatorial modes. The third criterion, the requirement of a mechanism for an accumulation of transient energy in the equatorial stretch flow (i.e., nonzero x), is not immediately obvious and requires exploration to develop new concepts.Using simple WKBJ arguments it is shown that within a realistic parameter range, a combination of longitudinal stretch in the basic state along the equator and the characteristics of the equatorial trapped waves satisfy the third criterion. The equatorial waves must possess a divergent structure which insists on equatorial trapping. It is shown that purely barotropic modes, which cannot be equatorially trapped, do not represent the real atmospheric structure at low latitudes. Regions of negative longitudinal stretch along the equator (i.e., westerlies decreasing, or easterlies increasing, towards the cast) are shown to be wave energy accumulation regions. Regions with positive stretch, on the other hand, are wave energy depletion regions. A free-surface barotropic model with fully nonlinear basic states, containing both stretch and shear, confirm the results of the simpler model, i.e., regardless of the position of the energy source within the tropical atmosphere the wave energy accumulates in the same region; namely, on the

  9. Energy management and effective energy use in Ukraine: basic problems and ways to solve them

    International Nuclear Information System (INIS)

    In this paper, barriers in the way of energy efficiency are considered and classified. The classification is made in six blocks: financial, sociological, manufacturing, management-organisational, legal and market. A strategy to overcome these barriers and the achievement of more effective energetics in Ukraine are proposed. On the basis of the strategy, five indissoluble tasks are considered: energy supply reliability, pricing and tariff policy, the legislative and normative base, energy use efficiency, environmental protection and decrease in influence on climate change. Solving these problems will allow the construction of an effective system of energy management in Ukraine. (author)

    The energy content per mile of installed underground and overhead power transmission systems has been calculated for the following types of systems: self-contained oil-filled cables; HPOF pipe-type cables; extruded dielectric cables; compressed-gas-insulated systems; overhead lines (ac and dc) and two proposed superconducting systems (ac and dc). The system operating voltages analyzed included 138, 230, 345, 500, 765 and 1,200 kV for ac systems, but all systems were not analyzed at the higher voltages. The dc overhead lines operated at +-200, +-400, +-600 and +-800 kV. Total installed energy content for these systems ranged from 4 x 10/sup 9/ to 1.2 x 10/sup 11/ Btu per mile. Installation energy requirements were generally 10% or less of the inherent system energy content based on the materials used in each system. Most of the energy content in each system can be attributed to the metallic components; plastic and insulating oil also contribute significantly. The energy content of 36 materials and basic products, in terms of Btu per ton, was calculated as part of this study. Substitution of conductor materials (e.g., aluminum for copper) in cable systems resulted in changes in the total system energy content on the order of 15%.

    Energy is fundamental to the quality of our lives. Nowadays, we are totally dependent on an abundant and continuous supply of energy for living and working. It is a key ingredient in all sectors of modern economies especially in industrial sector. In this paper we study the impacts of five variables on energy consumption and energy intensity in Iran's basic metal industry; number of occupied persons, investments, manufacturing value added, gas prices and electricity prices. Regression analysis using data of 20 years between 1987 and 2006 was performed. This study finds that MVA and energy prices are the most effective factors that influence the level of energy consumption. Another focus of this study is on predicting the future data using known past data. Fuzzy regression was used to forecast energy consumption until 2011; the results indicate that energy consumption will continue to grow higher. Finally a comparison between linear regression and fuzzy regression is presented to investigate different situations; this can be used to select the better method according to the situation we are dealing with.

    When stabilizing sewage sludge by means of fermentation, fermentation gas is released, consisting for 67% of methane. This gas is an important energy source for waste water treatment plants (wwtp). A previous STORA study (Fermentation gas as a source of energy in waste water treatment plants; 1981) has shown that the most significant energy saving in wwtps using sludge fermentation can be realized through energy generation. The aim of this study is to assess the current practical situation of wwtps that are in operation and generate their own energy. The main parameters in determining the appeal of own energy generation have been examined for these wwtps and compared to the technological and economic starting points of the study from 1981. The results indicate whether and which optimizations are possible for existing and new own systems for generating energy and which parameters from the previous STORA study need to be revised [Dutch] Bij stabilisatie van zuiveringsslib door middel van gisting komt gistingsgas vrij, dat voor circa 67% uit methaan bestaat. Dit gas vormt een belangrijke energiebron voor rioolwaterzuiveringsinrichtingen (rwzi). In een eerder STORA-onderzoek (Gistingsgas als energiebron op rioolwaterzuiveringsinrichtingen; 1981) is gebleken, dat de belangrijkste energiebesparing op rwzi's met slibgisting kan worden verkregen door toepassing van eigen energieopwekking. Doelstelling van deze studie is de huidige praktijksituatie op de reeds in bedrijf zijnde rwzi's met eigen energieopwekking na te gaan. De belangrijkste parameters die de aantrekkelijkheid van eigen energieopwekking bepalen, zijn voor deze rwzi's nader onderzocht en vergeleken met de technologische en economische uitgangspunten van het onderzoek uit 1981. De resultaten geven aan of en welke optimalisaties voor bestaande en nieuwe eigen energieopwekkingssystemen mogelijk zijn, en welke parameters in de eerdere STORA-studie opnieuw moeten worden bezien.

    The vision for the Summer Institute on Sustainability and Energy (SISE) is to integrate advancements in basic energy sciences with innovative energy technologies to train the next generation of interdisciplinary scientists and policy makers for both government and industry. Through BES related research, these future leaders will be equipped to make educated decisions about energy at the personal, civic, and global levels in energy related fields including science, technology, entrepreneurship, economics, policy, planning, and behavior. This vision explicitly supports the 2008 report by the Department of Energy’s Basic Energy Science Advisory Committee (2), which outlines scientific opportunities and challenges to achieve energy security, lower CO2 emissions, reduce reliance on foreign oil and create enduring economic growth through discovery, development and the marketing of new technologies for sustainable energy production, delivery, and use (3).

    than the choice of the mobility radius of the sink. Moreover, for small values of the duty cycle, a static sink turns out to be optimal in terms of both Emax and Ebar. For larger values of the duty cycle, a mobile sink has advantages over a static sink, especially in terms of Emax. These insights into the basic interrelationship between duty cycle value and mobility radius of a mobile sink are relevant for energy efficient operation of homogeneous WSNs beyond our model scenario.

  6. Energy Efficiency in Building as a Basic Prerequisite for a Long Term Energy Strategies Realization, Environmental Protection and Sustainability

    International Nuclear Information System (INIS)

    Energy efficiency in buildings at the low-energy and 'passive house' standard levels is presently the basic prerequisite for considering and formulating long term strategies, which with the task of meeting energy needs and system maintenance respond to requests of environmental protection and improvements in the context of sustainable development. Orientation to sustainable development is integrated in the development strategies of Croatia. The application of renewable energy sources, in particular solar energy in passive and active systems in the architecture is permanently confirmed by conducting energy monitoring and growing number of domestic studies, projects and realizations. The long-time research project of the European Union Cost Efficient Passive Houses as European Standards (CEPHEUS) with scientific monitoring corroborated energy and economic efficiency of such architectural designs in Germany, France, Austria, and Switzerland. Thus, the 'passive house' is proposed as a standard of residential architecture, but also of the construction of other functional types of architecture in general. The accomplished energy efficiency and verified favorable profitability of investment developed new forms of incentives to low-energy and passive architecture and relevant changes in concepts of long term energy strategies in the European Union member states. In Austria the 1000th passive house was built, and the city of Frankfurt/M brought decision regarding financing building construction through the city budget at the 'passive house' level. The new Technical Regulation on energy savings and thermal protection in Croatia, which is effectively in force as of 1 July, is a long-awaited step towards energy efficiency. Although, according to this Regulation the tolerance in energy use for space heating goes, in worst case calculation, up to 89 kWh/m2 a year, any other more favorable calculation with obligation to calculate the share of solar radiation for buildings, opens

    As an energy carrier, electricity has no rival with regard to its environmental cleanliness, flexibility in interfacing with multiple production sources and end uses, and efficiency of delivery. In fact, the electric power grid was named ?the greatest engineering achievement of the 20th century? by the National Academy of Engineering. This grid, a technological marvel ingeniously knitted together from local networks growing out from cities and rural centers, may be the biggest and most complex artificial system ever built. However, the growing demand for electricity will soon challenge the grid beyond its capability, compromising its reliability through voltage fluctuations that crash digital electronics, brownouts that disable industrial processes and harm electrical equipment, and power failures like the North American blackout in 2003 and subsequent blackouts in London, Scandinavia, and Italy in the same year. The North American blackout affected 50 million people and caused approximately $6 billion in economic damage over the four days of its duration. Superconductivity offers powerful new opportunities for restoring the reliability of the power grid and increasing its capacity and efficiency. Superconductors are capable of carrying current without loss, making the parts of the grid they replace dramatically more efficient. Superconducting wires carry up to five times the current carried by copper wires that have the same cross section, thereby providing ample capacity for future expansion while requiring no increase in the number of overhead access lines or underground conduits. Their use is especially attractive in urban areas, where replacing copper with superconductors in power-saturated underground conduits avoids expensive new underground construction. Superconducting transformers cut the volume, weight, and losses of conventional transformers by a factor of two and do not require the contaminating and flammable transformer oils that violate urban safety

    A procedure is presented to map from the spatial correlation parameters of a turbulent density field (the radial and binormal correlation lengths and wavenumbers, and the fluctuation amplitude) to correlation parameters that would be measured by a Beam Emission Spectroscopy (BES) diagnostic. The inverse mapping is also derived, which results in resolution criteria for recovering correct correlation parameters, depending on the spatial response of the instrument quantified in terms of Point-Spread Functions (PSFs). Thus, a procedure is presented that allows for a systematic comparison between theoretical predictions and experimental observations. This procedure is illustrated using the MAST BES system and the validity of the underlying assumptions is tested on fluctuating density fields generated by direct numerical simulations using the gyrokinetic code GS2. The measurement of the correlation time, by means of the cross-correlation time-delay (CCTD) method, is also investigated and is shown to be sensitive to...

  11. Radiation-resistance of polyurethane pipes for cooling liquid in BES III

    International Nuclear Information System (INIS)

    Gamma ray radiation and neutron radiation are predominant in the working conditions of BES III, and the radiation-resistance aging of polyurethane pipes is very important in this condition, as the pipes of cooling liquid for beam pipe and SCQ (superconducting quadrupole) vacuum pipe in BESIII. Polyester polyurethane pipes and polyether polyurethane pipes were irradiated by gamma ray and neutron. The radiation doses were as much as ten years' doses in BES. Pressure test, FTIR and thermal analysis were used to study the radiation-resistance of these two kinds of polyurethane pipes. The results show that the radiation-resistance and thermal stability of polyester polyurethane pipes are prior to those of polyether polyurethane pipes, and the pressure resistance of polyester polyurethane pipes is almost maintained after the irradiation by gamma ray and neutron, but the polyether polyurethane pipes can be aged and ruptured after the irradiation by neutron.

  13. Improving health, safety and energy efficiency in New Zealand through measuring and applying basic housing standards.

    Science.gov (United States)

    Gillespie-Bennett, Julie; Keall, Michael; Howden-Chapman, Philippa; Baker, Michael G

    2013-08-01

    Substandard housing is a problem in New Zealand. Historically there has been little recognition of the important aspects of housing quality that affect people's health and safety. In this viewpoint article we outline the importance of assessing these factors as an essential step to improving the health and safety of New Zealanders and household energy efficiency. A practical risk assessment tool adapted to New Zealand conditions, the Healthy Housing Index (HHI), measures the physical characteristics of houses that affect the health and safety of the occupants. This instrument is also the only tool that has been validated against health and safety outcomes and reported in the international peer-reviewed literature. The HHI provides a framework on which a housing warrant of fitness (WOF) can be based. The HHI inspection takes about one hour to conduct and is performed by a trained building inspector. To maximise the effectiveness of this housing quality assessment we envisage the output having two parts. The first would be a pass/fail WOF assessment showing whether or not the house meets basic health, safety and energy efficiency standards. The second component would rate each main assessment area (health, safety and energy efficiency), potentially on a five-point scale. This WOF system would establish a good minimum standard for rental accommodation as well encouraging improved housing performance over time. In this article we argue that the HHI is an important, validated, housing assessment tool that will improve housing quality, leading to better health of the occupants, reduced home injuries, and greater energy efficiency. If required, this tool could be extended to also cover resilience to natural hazards, broader aspects of sustainability, and the suitability of the dwelling for occupants with particular needs.

    Both sigma and kappa are well established from E791 data on D->3pi and D->K-pi-pi$ and BES II data on J/Psi->omega-pi-pi and KKpipi. Fits to these data are accurately consistent with pi-pi and Kpi elastic scattering when one allows for the Adler zero which arises from Chiral Symmetry Breaking. The phase variation with mass is also consistent between elastic scattering and production data.

    Videbaek, Flemming; STAR Collaboration

    2015-10-01

    STAR has proposed to upgrade the inner sectors of the STAR TPC to increase the segmentation on the inner padplane and to renew the inner sector wires. The upgrade will provide better momentum resolution, better dE/dx resolution and, most importantly, it will provide improved acceptance at high rapidity to | η| compared to the current TPC configuration of | η| energy trends that only appear near the edge of the current STAR acceptance. In the area of dielectron measurements it reduces hadron contamination from a dominant source of uncertainty to an expected statistical uncertainty of only 10%, and will enable significantly improved understanding of in-medium modifications. In this talk I will discuss the physics impact and give a technical overview of the detector upgrade. This work was supported in part by the Office of Nuclear Physics within the U.S. DOE Office of Science.

  20. Brief of BES-Belle-CLEO-BaBar 2007 joint workshop on charm physics

    International Nuclear Information System (INIS)

    The Institute of High Energy Physics of Chinese Academy of Sciences organized a workshop to establish closer contacts between experimentalists (theorists) involved in the studies of charm physics from both c and B communities. The workshop covers talks of physics analysis and its results from four electron-positron colliding experiments (BES, Belle, CLEO and BaBar). Presentations at the workshop are organized in the following sessions: (1) Hadron spectroscopy and new resonances; (2) D0-(D-)-bar mixing; (3) Charmonium decays; (4) Charm hadronic and (semi-)leptonic decays; (5) QCD at low energy and physics; (6) Partial wave analysis and Dalitz analysis, MC generator and Tools; (7) Detector upgrade. The workshop was held during November 26-27, 2007 in the Institute of High Energy Physics (IHEP). There are 90 registered participants in total, and 38 of them are from abroad (Japan, America, Russia, Italy, Germany, France, Slovenia, Switzerland and so on) and the others from China. All 35 talks were given in a plenary session. In an opening address, the director of IHEP, Professor CHEN Hesheng, has introduced the progress of BEPCI[ and BESIII construction and their preliminary performance at the current stage. First colliding of e+e- beam bunches in the BEPC II storage rings was achieved in March 2007, and soon later multi-bunch collisions with a current of 100 mA x 100 mA was also performed. The BESIII Main Drift Chamber, Time-of-Flight counter, Electro-Magnetic Calorimeter and muon counter, as well as Super-Conductor Magnet, are successfully installed. It is scheduled to move the detector in the colliding point in this April, and to start data taking in the June. Hadron spectroscopy is one of the most active field in c- and B-factories. Results from all four experiments, specially recent observations of exotic states and new structures, were reported and emphasized. The natures of these states were discussed extensively during the workshop, and multiquark, molecular or

    This report is based on a BES Workshop on Compact Light Sources, held May 11-12, 2010, to evaluated the advantages and disadvantages of compact light source approaches and compared their performance to the third generation storage rings and free-electron lasers. The workshop examined the state of the technology for compact light sources and their expected progress. The workshop evaluated the cost efficiency, user access, availability, and reliability of such sources. Working groups evaluated the advantages and disadvantages of Compact Light Source (CLS) approaches, and compared their performance to the third-generation storage rings and free-electron lasers (FELs). The primary aspects of comparison were 1) cost effectiveness, 2) technical availability v. time frame, and 3) machine reliability and availability for user access. Five categories of potential sources were analyzed: 1) inverse Compton scattering (ICS) sources, 2) mini storage rings, 3) plasma sources, 4) sources using plasma-based accelerators, and 5) laser high harmonic generation (HHG) sources. Compact light sources are not a substitute for large synchrotron and FEL light sources that typically also incorporate extensive user support facilities. Rather they offer attractive, complementary capabilities at a small fraction of the cost and size of large national user facilities. In the far term they may offer the potential for a new paradigm of future national user facility. In the course of the workshop, we identified overarching R&D topics over the next five years that would enhance the performance potential of both compact and large-scale sources: Development of infrared (IR) laser systems delivering kW-class average power with femtosecond pulses at kHz repetition rates. These have application to ICS sources, plasma sources, and HHG sources. Development of laser storage cavities for storage of 10-mJ picosecond and femtosecond pulses focused to micron beam sizes. Development of high-brightness, high

    The CP violation in the D system is predicted to be an unobserved level in the Standard Model. In this paper,we describe the method of searching for CP violation decay processes with the coherently produced D0(D)0 mesons from the ψ(3770) decay. The CP violation decay processes can be searched for at the BES-Ⅲ experiment. The experimental sensitivity for searching for the CP violation can reach about a 10-4 level with a ψ(3770) data sample of about 20 fb-1

  4. Materials Issues in Advanced Nuclear Systems: Executive Summary of DOE Basic Research Needs Workshop, 'Basic Research Needs for Advanced Nuclear Energy Systems'

    International Nuclear Information System (INIS)

    The global utilization of nuclear energy has come a long way from its humble beginnings in the first sustained nuclear reaction at the University of Chicago in 1942. Today, there are over 440 nuclear reactors in 31 countries producing approximately 16% of the electrical energy used worldwide. In the United States, 104 nuclear reactors currently provide 19% of electrical energy used nationally. The International Atomic Energy Agency projects significant growth in the utilization of nuclear power over the next several decades due to increasing demand for energy and environmental concerns related to emissions from fossil plants. There are 28 new nuclear plants currently under construction including 10 in China, 8 in India, and 4 in Russia. In the United States, there have been notifications to the Nuclear Regulatory Commission of intentions to apply for combined construction and operating licenses for 27 new units over the next decade. The projected growth in nuclear power has focused increasing attention on issues related to the permanent disposal of nuclear waste, the proliferation of nuclear weapons technologies and materials, and the sustainability of a once-through nuclear fuel cycle. In addition, the effective utilization of nuclear power will require continued improvements in nuclear technology, particularly related to safety and efficiency. In all of these areas, the performance of materials and chemical processes under extreme conditions is a limiting factor. The related basic research challenges represent some of the most demanding tests of our fundamental understanding of materials science and chemistry, and they provide significant opportunities for advancing basic science with broad impacts for nuclear reactor materials, fuels, waste forms, and separations techniques. Of particular importance is the role that new nanoscale characterization and computational tools can play in addressing these challenges. These tools, which include DOE synchrotron X

    Composite Fe2O3/ACF electrode facilitated methyl orange (MO) oxidative degradation using bio-electro-Fenton in bioelectrochemical system (BES) was investigated. Characterized by both XPS and FT-IR techniques, it was found that the composite Fe2O3/ACF electrode with highest Fe loading capacity of 11.02% could be prepared after the carbon felt was oxidized with nitric acid. Moreover, hydrogen peroxide production reached steadily at 88.63 μmol/L with the external resistance as 100 Ω, cathodic aeration rate at 750 mL/min, and the pH of the bio-electro-Fenton system adjusted to 2. Significantly, not only the electrochemical profiles of the BES reactor as electrochemical impedance spectroscopy (EIS) was bettered, but the MO oxidative degradation could be accomplished for eight repeated batches, with the MO removal efficiency varied slightly from 73.9% to 86.7%. It indicated that the bio-electro-Fenton might be a promising eco-friendly AOP method for Azo-dye wastewater treatment. PMID:26722807

    Full Text Available Common Slavic words *rěč', *slovo and *besěda all came to express, in different Slavic languages, the linguistic notion of 'word, speech', but each of those apparent synonyms has a (prehistory of its own. That of *rěč' is the least complicated: as a verbal noun from *rekti 'to say', it stands in the closest relationship to its object, which may explain the semantic development to 'thing'. *Slovo goes back to PIE *kléuos 'fame', which is also the prevalent meaning of its cognates in IE languages. As an exception Avestan sravah- does not mean 'word', as it had been taken for granted for a long time, but rather 'eulogy, hymn'. Not unlike it -and Homeric Pl. kléa andrôn- Pre-Christian *slovo seems to have been a solemn, especially commemorative speech, a funeral lamentation, an epic poem. In translating the Holy Scripture into Slavonic it apparently met Greek logos in the rhetorical part of its semantic field, and only secondarily expanded onto the lexical one. As for *besěda, its proper sense is 'a speech in public', which developed from 'a meeting(-place in the open'; it is convincingly analyzable as *bez-sěda, 'sitting outside', a compound etymologically matched, in Old Indian, by the adjective bahih-sad- meaning the same (used of a gambler.

    In this paper the elastic and thermodynamic properties of the cubic zinc-blende structure BeS at different pressures and temperatures are investigated by using ab initio plane-wave pseudopotential density functional theory method within the generalized gradient approximation (GGA). The calculated results are in excellent agreement with the available experimental data and other theoretical results. It is found that the zinc-blende structure BeS should be unstable above 60GPa. The thermodynamic properties of the zinc-blende structure BeS are predicted by using the quasi-harmonic Debye model. The pressure-volume-temperature (P - V - T) relationship, the variations of the thermal expansion coefficient and the heat capacity Cv with pressure P and temperature T, as well as the Grüneisen parameter-pressure-temperature (γ- P - T) relationship are obtained systematically in the ranges of 0-90GPa and 0-2000K.

This is important because these concepts are crucial in the on-going transformation from the fossil carbon based to renewable energy based societies, but still the use of the concepts has been confusing. SE consists of the integration of rational use of energy (energy saving, energy efficiency, use of renewable energy sources and sustainability management for anticipating, avoiding and reducing adverse impacts. The best consensus for defining DE is “facilities connected to the distribution network or on the customer side of the meter”. Devices using fossil fuels but otherwise falling under this umbrella cannot be excluded from DE. This paper explores definitions of wind power in relation to its grid connections via DE. SE is more comprehensive embracing the whole field of energy management, with the exception of distributed fossil generation. SE is valuable for understanding, planning and implementing energy strategies in the transition process of the energy sector. SE also includes centralized energy. It is useful for planning at national or sub-national geographic regions. The combination Sustainable Distributed Energy (SDE is excellent for regional contexts and for creating regional renewable energy self-sufficiency, integrated with society-wide energy saving and energy efficiency programs.

    The use of chemometric techniques and multivariate experimental designs for the photocatalytic reaction of reactive scarlet BES in aqueous solution under ultraviolet light irradiation is described. The efficiency of photocatalytic degradation was evaluated by the analysis of the parameter of decoloration efficiency determined by UV absorption at 540 nm using a UV-Vis spectrophotometer in different conditions. Five factors, such as the amount of titanium oxide ([TiO2]), the concentrations of reactive scarlet BES (c(0)), irradiation time (t), the pH value (pH) and temperature (T), were studied. [TiO2]. c(0), t and pH selected on the basis of the results of variance analysis by Plackett-Burman design were used as independent variables. Training sets and test sets of back propagation neural network (BPNN) were formed by Box-Behnken design and uniform design U10 (10 x 5(2) x 2) respectively. The process of photocatalytic degradation of the target object was simulated by the BPNN model. The correlation coefficient (r) of the calculation results for training set and test set by BPNN is 0.996 4 and 0.963 6 respectively, and the mean relative errors between the predictive value and experimental value of decoloration efficiency are 6.14 and 7.76, respectively. The modeled BPNN was applied to analyze the influence of four factors on decoloration efficiency. The results showed that the initial conditions of c(0) being lower, pH 5.0 and appropriate amount of [TiO2] contribute to improving the decoloration efficiency of reactive scarlet BES. Under the condition of c(0) = 40 mg x L(-1), the optimized experimental condition of the system was obtained: [TiO2] = 1.20 g x L(-1) and pH 5.0. Under the optimized experimental condition, the experimental value of decoloration efficiency is 98.20% when irradiation time is 35 minutes and the predictive value of decoloration efficiency is 99.16% under the same condition. The relative error of decoloration efficiency between the predictive

In response, the Office of Science, through its Office of Basic Energy Science (BES), convened a roundtable consisting of 15 national lab, university and industry geoscience experts to brainstorm basic research areas that underpin the SubTER goals but are currently underrepresented in the BES research portfolio. Held in Germantown, Maryland on May 22, 2015, the round-table participants developed a basic research agenda that is detailed in this report. Highlights include the following: -A grand challenge calling for advanced imaging of stress and geological processes to help understand how stresses and chemical substances are distributed in the subsurface—knowledge that is critical to all aspects of subsurface engineering; -A priority research direction aimed at achieving control of fluid flow through fractured media; -A priority research direction aimed at better understanding how mechanical and geochemical perturbations to subsurface rock systems are coupled through fluid and mineral interactions; -A priority research direction aimed at studying the structure, permeability, reactivity and other properties of nanoporous rocks, like shale, which have become critical energy materials and exhibit important hallmarks of mesoscale materials; -A cross-cutting theme that would accelerate development of advanced computational methods to describe heterogeneous time-dependent geologic systems that could, among other potential benefits, provide new and vastly improved models of hydraulic fracturing and its environmental impacts; -A cross-cutting theme that would lead to the creation of “geo-architected materials” with controlled repeatable heterogeneity and structure that can be tested under a variety of thermal, hydraulic, chemical and mechanical conditions relevant to subsurface systems; -A cross-cutting theme calling for new laboratory studies on both natural and geo-architected subsurface materials that deploy advanced high-resolution 3D imaging and chemical analysis

    Research at the Interface of Marine Hydrokinetic Energy and the Environment: A Workshop; Minneapolis, Minnesota, 5-7 October 2011 Marine and hydrokinetic (MHK) energy harvesting technologies convert the kinetic energy of waves and water currents into power to generate electricity. Although these technologies are in early stages of development compared to other renewable technologies, such as solar and wind energy, they offer electricity consumers situated near coastlines or inland rivers an alternative energy technology that can help meet renewable portfolio standards. However, the potential environmental impacts of MHK energy are far from well understood, both in general principles and in site-specific cases. As pressure for new MHK energy licenses builds, accelerated research in providing the scientific understanding of harnessing the natural power of water for renewable energy at a competitive cost and without harming the environment becomes a priority.

    2015-01-01

    A Bayesian model of the emission spectrum of the JET lithium beam has been developed to infer the intensity of the Li I (2p-2s) line radiation and associated uncertainties. The detected spectrum for each channel of the lithium beam emission spectroscopy (Li-BES) system is here modelled by a single Li line modified by an instrumental function, Bremsstrahlung background, instrumental offset, and interference filter curve. Both the instrumental function and the interference filter curve are modelled with non-parametric Gaussian processes. All free parameters of the model, the intensities of the Li line, Bremsstrahlung background, and instrumental offset, are inferred using Bayesian probability theory with a Gaussian likelihood for photon statistics and electronic background noise. The prior distributions of the free parameters are chosen as Gaussians. Given these assumptions, the intensity of the Li line and corresponding uncertainties are analytically available using a Bayesian linear inversion technique. The p...

    de Guzman, C. P.; Andrianarijaona, M.; Lee, Y. S.; Andrianarijaona, V.

    An extensive knowledge of the ionization energies of amino acids can provide vital information on protein sequencing, structure, and function. Acidic and basic amino acids are unique because they have three ionizable groups: the C-terminus, the N-terminus, and the side chain. The effects of multiple ionizable groups can be seen in how Aspartate's ionizable side chain heavily influences its preferred conformation (J Phys Chem A. 2011 April 7; 115(13): 2900-2912). Theoretical and experimental data on the ionization energies of many of these molecules is sparse. Considering each atom of the amino acid as a potential departing site for the electron gives insight on how the three ionizable groups affect the ionization process of the molecule and the dynamic coupling between the vibrational modes. In the following study, we optimized the structure of each acidic and basic amino acid then exported the three dimensional coordinates of the amino acids. We used ORCA to calculate single point energies for a region near the optimized coordinates and systematically went through the x, y, and z coordinates of each atom in the neutral and ionized forms of the amino acid. With the calculations, we were able to graph energy potential curves to better understand the quantum dynamic properties of the amino acids.

    2014-04-01

    Full Text Available With the present understanding of data, the observed flux suppression for ultra-high energy cosmic rays (UHECR at energies above 4.1019 eV can be a signature of the Greisen-Zatsepin-Kuzmin (GZK cutoff or be related to a similar mechanism. But it may also correspond, for instance, to the maximum energies available at the relevant sources. In both cases, violations of special relativity modifying cosmic-ray propagation or acceleration at very high energy can potentially play a role. Other violations of fundamental principles of standard particle physics (quantum mechanics, energy and momentum conservation, vacuum homogeneity and “static” properties, effective space dimensions, quark confinement… can also be relevant at these energies. In particular, UHECR data would in principle allow to set bounds on Lorentz symmetry violation (LSV in patterns incorporating a privileged local reference frame (the “vacuum rest frame”, VRF. But the precise analysis is far from trivial, and other effects can also be present. The effective parameters can be related to Planckscale physics, or even to physics beyond Planck scale, as well as to the dynamics and effective symmetries of LSV for nucleons, quarks, leptons and the photon. LSV can also be at the origin of GZK-like effects. In the presence of a VRF, and contrary to a “grand unification” view, LSV and other violations of standard principles can modify the internal structure of particles at very high energy and conventional symmetries may cease to be valid at energies close to the Planck scale. We present an updated discussion of these topics, including experimental prospects, new potentialities for high-energy cosmic ray phenomenology and the possible link with unconventional pre-Big Bang scenarios, superbradyon (superluminal preon patterns… The subject of a possible superluminal propagation of neutrinos at accelerator energies is also dealt with.

    International Nuclear Information System (INIS)

    The Energy Research Supercomputer Users Group (ERSUG) comprises all investigators using resources of the Department of Energy Office of Energy Research supercomputers. At the December 1989 meeting held at Florida State University (FSU), the ERSUG executive committee determined that the continuing rapid advances in computational sciences and computer technology demanded a reassessment of the role computational science should play in meeting DOE's commitments. Initial studies were to be performed for four subdivisions: (1) Basic Energy Sciences (BES) and Applied Mathematical Sciences (AMS), (2) Fusion Energy, (3) High Energy and Nuclear Physics, and (4) Health and Environmental Research. The first two subgroups produced formal subreports that provided a basis for several sections of this report. Additional information provided in the AMS/BES is included as Appendix C in an abridged form that eliminates most duplication. Additionally, each member of the executive committee was asked to contribute area-specific assessments; these assessments are included in the next section. In the following sections, brief assessments are given for specific areas, a conceptual model is proposed that the entire computational effort for energy research is best viewed as one giant nation-wide computer, and then specific recommendations are made for the appropriate evolution of the system

  3. The Path to Sustainable Nuclear Energy. Basic and Applied Research Opportunities for Advanced Fuel Cycles, September 12-14, 2005

    International Nuclear Information System (INIS)

    The objective of this report is to identify new basic science that will be the foundation for advances in nuclear fuel-cycle technology in the near term, and for changing the nature of fuel cycles and of the nuclear energy industry in the long term. The goals are to enhance the development of nuclear energy, to maximize energy production in nuclear reactor parks, and to minimize radioactive wastes, other environmental impacts, and proliferation risks. The limitations of the once-through fuel cycle can be overcome by adopting a closed fuel cycle, in which the irradiated fuel is reprocessed and its components are separated into streams that are recycled into a reactor or disposed of in appropriate waste forms. The recycled fuel is irradiated in a reactor, where certain constituents are partially transmuted into heavier isotopes via neutron capture or into lighter isotopes via fission. Fast reactors are required to complete the transmutation of long-lived isotopes. Closed fuel cycles are encompassed by the Department of Energy?s Advanced Fuel Cycle Initiative (AFCI), to which basic scientific research can contribute. Two nuclear reactor system architectures can meet the AFCI objectives: a ?single-tier? system or a ?dual-tier? system. Both begin with light water reactors and incorporate fast reactors. The ?dual-tier? systems transmute some plutonium and neptunium in light water reactors and all remaining transuranic elements (TRUs) in a closed-cycle fast reactor. Basic science initiatives are needed in two broad areas: ? Near-term impacts that can enhance the development of either ?single-tier? or ?dual-tier? AFCI systems, primarily within the next 20 years, through basic research. Examples: Dissolution of spent fuel, separations of elements for TRU recycling and transmutation Design, synthesis, and testing of inert matrix nuclear fuels and non-oxide fuels Invention and development of accurate on-line monitoring systems for chemical and nuclear species in the nuclear

    It has not yet been elucidated whether the observed flux suppression for ultra-high energy cosmic rays (UHECR) at energies above ≃ 4 x 1019 eV is a signature of the Greisen-Zatsepin-Kuzmin (GZK) cutoff or a consequence of other phenomena. In both cases, violations of the standard fundamental principles of Physics can be present and play a significant role. They can in particular modify cosmic-ray interactions, propagation or acceleration at very high energy. Thus, in a long-term program, UHECR data can hopefully be used to test relativity, quantum mechanics, energy and momentum conservation, vacuum properties... as well as the elementariness of standard particles. Data on cosmic rays at energies ≃ 1020 eV may also be sensitive to new physics generated well beyond Planck scale. A typical example is provided by the search for possible signatures of a Lorentz symmetry violation (LSV) associated to a privileged local reference frame (the "vacuum rest frame", VRF). If a VRF exists, the internal structure of standard particles at ultra-high energy can undergo substantial modifications. Similarly, the conventional particle symmetries may cease to be valid at such energies instead of heading to a grand unification and the structure of vacuum may no longer be governed by standard quantum field theory. Then, the question whether the notion of Planck scale still makes sense clearly becomes relevant and the very grounds of Cosmology can undergo essential modifications. UHECR studies naturally interact with the interpretation of WMAP and Planck observations. Recent Planck data analyses tend to confirm the possible existence of a privileged space direction. If the observed phenomenon turns out to be a signature of the spinorial space-time (SST) we suggested in 1996-97, then conventional Particle Physics may correspond to the local properties of standard matter at low enough energy and large enough distances. This would clearly strengthen the cosmological relevance of UHECR

Research and development must respond to these changes by making technological innovations and proposing solutions that are safe, competitive, economic with regard to natural resources and respectful of the environment. The French ''Commissariat a l'Energie Atomique et aux energies alternatives'' (CEA) has a leading role to play through its large range of activities: fundamental research and technological research in various fields from biology to nuclear sciences via energy efficiency of buildings and solar energy and through its access to big experimental facilities like Orphee and Osiris reactors or peta-watt Lasers or Soleil synchrotron

  8. The zero-point field. On the search for the cosmic basic energy

    International Nuclear Information System (INIS)

    Does an inexhaustable energy source exist from which all life is fed? A form of energy, which penetrates all dead and living expression forms of life? Does a logical, scientific explanation exist for parapsychological phenomena like clairvoyance, telepathy, ghost healing, synchronicity, and a model for the mode of action of homeopathy? Do serious researchers and scientific studies to be token in ernest exist, which not only deal with this questions but also have found answers? During eight years the British scientific journalist Lynne McTaggart has researched. ''Teh zero-point field'' is the result of numerous speeches with renowned physicists, biophysicists, neuroscientists, biologist, and consciousness researchers on the whole world, which have independently discovered phenomena, which are combined like puzzle pieces to a fascinating total picture.

    The processes whereby people make decisions about specific behavior, the forces that operate on these decisions, and the interaction of several decisions and their modifying effect upon each other are studied. An overview of the current approach to decision study and behavior-change studies is presented. Brief papers prepared by such experts as Maccoby, Tversky, Cialdine, Margolin, Simon, Heider, Festinger, and Lervin are presented. Methodological considerations are discussed. Task B focuses on the specific issue of the purchase of energy-efficient appliances. Task C investigates individual and small-group data-quantification techniques. Task D explains monitoring of ongoing energy-relevant consumer/purchaser surveys. A cost-benefit analysis is made and discussed in Task E of other public and private information programs designed to serve the public welfare. A number of useful findings are presented with the caveat that cost-benefit analysis is not a precise technique. The application of this study to the needs of the energy-conservation program is summarized. (MCW)

    The paper presents my recent investigations of volume corrections on the cumulant products of net-charge distributions in statistical model, corresponding to the data reported by the STAR collaboration. The corrected statistical expectations, under simple Poisson approximations, can reasonably explain the data measured in experiment. The results indicate that volume corrections play crucial role in event-by-event multiplicity fluctuation studies.

    A PCO Pixelfly VGA CCD camera which is part a of the Beam Emission Spectroscopy (BES) diagnostic system of the Korea Superconducting Tokamak Advanced Research (KSTAR) used for spatial calibrations, suffered from serious radiation damage, white pixel defects have been generated in it. The main goal of this work was to identify the origin of the radiation damage and to give solutions to avoid it. Monte Carlo N-Particle eXtended (MCNPX) model was built using Monte Carlo Modeling Interface Program (MCAM) and calculations were carried out to predict the neutron and gamma-ray fields in the camera position. Besides the MCNPX calculations pure gamma-ray irradiations of the CCD camera were carried out in the Training Reactor of BME. Before, during and after the irradiations numerous frames were taken with the camera with 5 s long exposure times. The evaluation of these frames showed that with the applied high gamma-ray dose (1.7 Gy) and dose rate levels (up to 2 Gy/h) the number of the white pixels did not increase. We have found that the origin of the white pixel generation was the neutron-induced thermal hopping of the electrons which means that in the future only neutron shielding is necessary around the CCD camera. Another solution could be to replace the CCD camera with a more radiation tolerant one for example with a suitable CMOS camera or apply both solutions simultaneously.

    2013-07-01

    Full Text Available Artiklen redegør for, hvilke udfordringer en mindre dansk industrivirksomhed uden umiddelbar bevågenhed fra værnemagten og den tyske krigsindustri stod overfor under besættelsen, og hvorledes en sådan virksomhed mødte disse udfordringer. Samtidig lægger artiklen vægt på, hvilken betydning, det havde, at fabrikken fremstillede en for besættelsestiden såkaldt luksusvare. Desuden diskuteres det, hvilke ligheder og forskelle, der var i forhold til Randers Handskefabriks muligheder under besættelsen og for den danske industri som helhed.Udbruddet af Anden Verdenskrig og den efterfølgende tyske besættelse af Danmark i 1940 betød, at Randers Handskefabriks hidtidige import af skind i første omgang blev pålagt restriktioner og siden stort set ophørte. Fabrikken måtte derfor vænne sig til en produktion med danske kalveskind og forskellige erstatningsvarer i takt med, at de sædvanlige handskeskind forsvandt fra markedet. Randers Handskefabrik havde dog opbygget et stort lager inden krigen. Her opbevarede man de bedste skind. Skindene blev under besættelsen lavet til – forholdende taget i betragtning - eksklusive handsker og solgt til udvalgte kunder. At det var de udvalgte og ofte velhavende kunder, der modtog de fineste handsker, understreger, at det under besættelsen ofte var de mindre velstillede, der oplevede mangler, mens man, hvis man havde penge nok, kunne opretholde en høj levestandard. Priserne steg under besættelsen, og var for industrien som helhed medvirkende til, at denne sektor havde gode vilkår i forhold til at skabe profit på sine produkter. Der var dog stadig for en lang række virksomheder tale om, at de var underlagt en maksimalpris på deres varer. Handskebranchen nød under hele besættelsen godt af ikke at blive underlagt disse prisbegrænsninger på handskerne, og i det hele taget regerede de frie markedskræfter på markedet for handsker i stort set alle besættelsesårene. Generelt formåede Randers

    2014-03-01

    The last few years have yielded remarkable discoveries in physics. In particle physics it appears that a fundamental scalar field exists. The Higgs boson is measured to have a mass of about 126 GeV and to have spin zero and positive parity. The Higgs field is the first fundamental scalar to be discovered in physics. The Cosmic Microwave Background, CMB, is known to have a uniform temperature to parts per 105 but has well measured fluctuations which are thought to evolve gravitationally to provide the seeds of the current structure of the Universe. In addition, the Universe appears to contain, at present, an unknown “dark energy” which is presently the majority energy density of the Universe, larger than either matter or radiation. This may, indeed, be a fundamental scalar field like the Higgs. “Big Bang” (BB) cosmology is a very successful “standard model” in cosmology. However, it cannot explain the uniformity of the CMB because the CMB consists of many regions not causally connected in the context of the BB model. In addition, the Universe appears to be spatially flat. However in BB cosmology the present spatial curvature is not stable so that the initial conditions for BB cosmology would need to be fantastically fine-tuned in order to successfully predict the presently small value of the observed curvature. These issues for BB cosmology have led to the hypothesis of “inflation” which postulates an unknown scalar field, not presumably the Higgs field or the dark energy, which causes an exponential expansion of the Universe at very early times. This attractive hypothesis can account for the problems in BB cosmology of flatness and causal CMB connectivity. In addition, the quantum fluctuations of this postulated field provide a natural explanation of the CMB fluctuations which are the seeds of the structure of galaxies. Researchers are now searching for gravitational waves imprinted on the CMB. These would be a “smoking gun” for

    On the basis of the nonlinear stability theorem in the context of Arnol' d's second theorem for the generalized Phillips model, nonlinear saturation of baroclinic instability in the generalized Phillips model is investigated. The lower bound on the disturbance energy and potential enstrophy to the nonlinearly unstable basic flow in the generalized Phillips model is presented, which indicates that there may exist an allocation between a nonlinearly unstable basic flow and a growing disturbance.

    The workshop participants enthusiastically concluded that the time is ripe for new fundamental science to beget a revolution in lighting technology. SSL sources based on organic and inorganic materials have reached a level of efficiency where it is possible to envision their use for general illumination. The research areas articulated in this report are targeted to enable disruptive advances in SSL performance and realization of this dream. Broad penetration of SSL technology into the mass lighting market, accompanied by vast savings in energy usage, requires nothing less. These new ?good ideas? will be represented not by light bulbs, but by an entirely new lighting technology for the 21st century and a bright, energy-efficient future indeed.

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

  14. BES1 regulates the localization of the brassinosteroid receptor BRL3 within the provascular tissue of the Arabidopsis primary root.

    Brassinosteroid (BR) hormones are important regulators of plant growth and development. Recent studies revealed the cell-specific role of BRs in vascular and stem cell development by the action of cell-specific BR receptor complexes and downstream signaling components in Arabidopsis thaliana Despite the importance of spatiotemporal regulation of hormone signaling in the control of plant vascular development, the mechanisms that confer cellular specificity to BR receptors within the vascular cells are not yet understood. The present work shows that BRI1-like receptor genes 1 and 3 (BRL1 and BRL3) are differently regulated by BRs. By using promoter deletion constructs of BRL1 and BRL3 fused to GFP/GUS (green fluorescent protein/β-glucuronidase) reporters in Arabidopsis, analysis of their cell-specific expression and regulation by BRs in the root apex has been carried out. We found that BRL3 expression is finely modulated by BRs in different root cell types, whereas the location of BRL1 appears to be independent of this hormone. Physiological and genetic analysis show a BR-dependent expression of BRL3 in the root meristem. In particular, BRL3 expression requires active BES1, a central transcriptional effector within the BRI1 pathway. ChIP analysis showed that BES1 directly binds to the BRRE present in the BRL3 promoter region, modulating its transcription in different subsets of cells of the root apex. Overall our study reveals the existence of a cell-specific negative feedback loop from BRI1-mediated BES1 transcription factor to BRL3 in phloem cells, while contributing to a general understanding of the spatial control of steroid signaling in plant development.

  15. Integrating membrane filtration into bioelectrochemical systems as next generation energy-efficient wastewater treatment technologies for water reclamation: A review.

    Science.gov (United States)

    Yuan, Heyang; He, Zhen

    2015-11-01

    Bioelectrochemical systems (BES) represent an energy-efficient approach for wastewater treatment, but the effluent still requires further treatment for direct discharge or reuse. Integrating membrane filtration in BES can achieve high-quality effluents with additional benefits. Three types of filtration membranes, dynamic membrane, ultrafiltration membrane and forward osmosis membrane that are grouped based on pore size, have been studied for integration in BES. The integration can be accomplished either in an internal or an external configuration. In an internal configuration, membranes can act as a separator between the electrodes, or be immersed in the anode/cathode chamber as a filtration component. The external configuration allows BES and membrane module to be operated independently. Given much progress and interest in the integration of membrane filtration into BES, this paper has reviewed the past studies, described various integration methods, discussed the advantages and limitations of each integration, and presented challenges for future development.

Three types of filtration membranes, dynamic membrane, ultrafiltration membrane and forward osmosis membrane that are grouped based on pore size, have been studied for integration in BES. The integration can be accomplished either in an internal or an external configuration. In an internal configuration, membranes can act as a separator between the electrodes, or be immersed in the anode/cathode chamber as a filtration component. The external configuration allows BES and membrane module to be operated independently. Given much progress and interest in the integration of membrane filtration into BES, this paper has reviewed the past studies, described various integration methods, discussed the advantages and limitations of each integration, and presented challenges for future development.

    . In response, the Office of Science, through its Office of Basic Energy Science (BES), convened a roundtable consisting of 15 national lab, university and industry geoscience experts to brainstorm basic research areas that underpin the SubTER goals but are currently underrepresented in the BES research portfolio. Held in Germantown, Maryland on May 22, 2015, the round-table participants developed a basic research agenda that is detailed in this report. Highlights include the following: -A grand challenge calling for advanced imaging of stress and geological processes to help understand how stresses and chemical substances are distributed in the subsurface—knowledge that is critical to all aspects of subsurface engineering; -A priority research direction aimed at achieving control of fluid flow through fractured media; -A priority research direction aimed at better understanding how mechanical and geochemical perturbations to subsurface rock systems are coupled through fluid and mineral interactions; -A priority research direction aimed at studying the structure, permeability, reactivity and other properties of nanoporous rocks, like shale, which have become critical energy materials and exhibit important hallmarks of mesoscale materials; -A cross-cutting theme that would accelerate development of advanced computational methods to describe heterogeneous time-dependent geologic systems that could, among other potential benefits, provide new and vastly improved models of hydraulic fracturing and its environmental impacts; -A cross-cutting theme that would lead to the creation of “geo-architected materials” with controlled repeatable heterogeneity and structure that can be tested under a variety of thermal, hydraulic, chemical and mechanical conditions relevant to subsurface systems; -A cross-cutting theme calling for new laboratory studies on both natural and geo-architected subsurface materials that deploy advanced high-resolution 3D imaging and chemical analysis

    Observations of ion-scale (k_y*rho_i <= 1) density turbulence of relative amplitude dn_e/n_e <= 0.2% are available on the Mega Amp Spherical Tokamak (MAST) using a 2D (8 radial x 4 poloidal channel) imaging Beam Emission Spectroscopy (BES) diagnostic. Spatial and temporal characteristics of this turbulence, i.e., amplitudes, correlation times, radial and perpendicular correlation lengths and apparent phase velocities of the density contours, are determined by means of correlation analysis. For a low-density, L-mode discharge with strong equilibrium flow shear exhibiting an internal transport barrier (ITB) in the ion channel, the observed turbulence characteristics are compared with synthetic density turbulence data generated from global, non-linear, gyro-kinetic simulations using the particle-in-cell (PIC) code NEMORB.

    1995-01-01

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames. Chapter 2 introduces the wavelet transform, contrasts it with the short-time Fourier transform and clarifies the names of the different types of wavelet transforms. Chapter 3 links multiresolution analysis, orthonormal wavelets and the design of digital filters. Chapter 4 gives a tour d'horizon of topics of current interest: wave...

    Over the past five years, the Department of Energy's Office of Basic Energy Sciences has engaged thousands of scientists around the world to study the current status, limiting factors and specific fundamental scientific bottlenecks blocking the widespread implementation of alternate energy technologies. The reports from the foundational BESAC workshop, the ten 'Basic Research Needs' workshops and the panel on Grand Challenge science detail the necessary research steps (http://www.sc.doe.gov/bes/reports/list.html). This report responds to a charge from the Director of the Office of Science to the Basic Energy Sciences Advisory Committee to conduct a study with two primary goals: (1) to assimilate the scientific research directions that emerged from these workshop reports into a comprehensive set of science themes, and (2) to identify the new implementation strategies and tools required to accomplish the science. From these efforts it becomes clear that the magnitude of the challenge is so immense that existing approaches - even with improvements from advanced engineering and improved technology based on known concepts - will not be enough to secure our energy future. Instead, meeting the challenge will require fundamental understanding and scientific breakthroughs in new materials and chemical processes to make possible new energy technologies and performance levels far beyond what is now possible.

    Science.gov (United States)

    Gonzalez-Mestres, L.

    2014-04-01

    With the present understanding of data, the observed flux suppression for ultra-high energy cosmic rays (UHECR) at energies above 4.1019 eV can be a signature of the Greisen-Zatsepin-Kuzmin (GZK) cutoff or be related to a similar mechanism. But it may also correspond, for instance, to the maximum energies available at the relevant sources. In both cases, violations of special relativity modifying cosmic-ray propagation or acceleration at very high energy can potentially play a role. Other violations of fundamental principles of standard particle physics (quantum mechanics, energy and momentum conservation, vacuum homogeneity and "static" properties, effective space dimensions, quark confinement…) can also be relevant at these energies. In particular, UHECR data would in principle allow to set bounds on Lorentz symmetry violation (LSV) in patterns incorporating a privileged local reference frame (the "vacuum rest frame", VRF). But the precise analysis is far from trivial, and other effects can also be present. The effective parameters can be related to Planckscale physics, or even to physics beyond Planck scale, as well as to the dynamics and effective symmetries of LSV for nucleons, quarks, leptons and the photon. LSV can also be at the origin of GZK-like effects. In the presence of a VRF, and contrary to a "grand unification" view, LSV and other violations of standard principles can modify the internal structure of particles at very high energy and conventional symmetries may cease to be valid at energies close to the Planck scale. We present an updated discussion of these topics, including experimental prospects, new potentialities for high-energy cosmic ray phenomenology and the possible link with unconventional pre-Big Bang scenarios, superbradyon (superluminal preon) patterns… The subject of a possible superluminal propagation of neutrinos at accelerator energies is also dealt with.

  13. Energy consumption practices of rural households in north China: Basic characteristics and potential for low carbon development

    International Nuclear Information System (INIS)

    Reducing the climate impact of rural household energy consumption in China is complicated since it is bound up with deeply routinized daily practices and dependent from existing infrastructural systems of energy supply. To assess the potential for low carbon development we first estimate the overall CO2 emissions of rural households, followed by a more in depth description and characterization of the different energy use practices within the households. Space heating turns out to be the largest emission source among domestic energy practices in north China. We present lifestyle and context related factors that help to explain existing differences in domestic energy use practices of households. The potential for low carbon development is discussed both at the demand side and the supply side. At the demand side, the use of more efficient technologies and cleaner energy sources for space heating seems to be a high potential measure for achieving low carbon households. At the supply side the reduction of rural domestic CO2 emissions could be effectively supported by making available to householders renewable and cleaner energy sources and technologies. In order to be effective, such low carbon energy options should take into account the (income) characteristics and lifestyles of rural householders. - Highlights: ► Rural household energy use and CO2 emissions in China are investigated via a field survey. ► Energy use and CO2 emissions are related to separate practices within households. ► Improvements in CO2 emission reduction are possible at demand side and supply side. ► Income and education are proven to be positively correlated with household emissions

    The proton affinities, gas phase basicities and adiabatic ionization energies and electron affinities of some important hydroxylamines and alkanolamines were calculated using B3LYP, CBS-Q and G4MP2 methods. Also, the B3LYP method was used to calculate vertical ionization energies and electron affinities of the molecules. The calculated ionization energies are in the range of 8-10.5 eV and they decrease as the number of carbon atoms increases. Computational results and ion mobility spectrometry study confirm that some alkanolamines lose a water molecule due to protonation at oxygen site and form cationic cyclic compounds. Effect of different substitutions on the cyclization of ethanolamine was studied theoretically.

    This study describes how the ''Energy Efficient City'' competition is intended to promote activities towards greater energy efficiency which relate to cities as systems, are innovative, and conceive of and incorporate services as part of the solution. ''Innovation with services'' is not only about the further development of existing services but more particularly about the creation of high-quality services in growth areas which can serve to speed up innovation and create new application potentials for technical developments. They should be based on a holistic view on urban processes of energy use and energy supply and give consideration to all relevant stakeholders. The ''Energy Efficient City'' competition is aimed at systematically linking innovations with services to energy efficiency issues. The implementation of these goals will be facilitated by accompanying research. To this end the present text provides information on how services can be geared to energy efficiency.

    Theoretical incompleteness of the existing conservation laws of energy for polar continuum mechanics is further clarified. For completeness, the principles of total work and energy and of total work and energy of incremental rate type are postulated. Via total variations of the former and the latter of them, the principles of virtual displacement and microrotation & stress and couple stress as well as virtual velocity and angular velocity &stress rate and couple stress rate are immediately obtained, respectively. From these principles all balance equations and boundary conditions for micropolar mechanics are naturally and simultaneously deduced. The essential differences between the nontraditional results obtained in this paper and the existing conservation laws of energy are expounded.

    Highlights: • We point to a not seriously solved conflict in energy scale referencing of Li metal samples in XPS. • Model experiments at Li-, Na-metal and Li-doped HOPG samples were used to classify the effects. • Binding energy shifts up to 3 eV are observed when the alkaline metal is present in metallic state. • A phenomenological explanation based on an electrostatic interaction is suggested. • Consequences for energy scale correction depending on the kind of surface species are followed. - Abstract: For the investigation of chemical changes in Li- and Na-ion battery electrode systems, X-ray photoelectron spectroscopy (XPS) is a well-accepted method. Charge compensation and referencing of the binding energy (BE) scale is necessary to account for the involved mostly non-conducting species. Motivated by a conflict in energy scale referencing of Li-metal samples discussed earlier by several authors, further clarifying experimental results on several Li containing reference materials are presented and extended by similar experiments for Na. When correlating the peak positions of characteristic chemical species in all the different prepared model sample states, there seems to be a systematic deviation in characteristic binding energies of several eV if lithium is present in its metallic state. Similar results were found for sodium. The observations are furthermore confirmed by the implementation of inert artificial energy reference material, such as implanted argon or deposited gold. The behavior is associated with the high reactivity of metallic lithium and a phenomenological explanation is proposed for the understanding of the observations. Consequences for data interpretation in Li-ion battery research will be discussed for various applications in part (II)

This model is used to calculate basic observables of nuclear multifragmentation like mass distribution, fragment multiplicity, isotopic distribution and isoscaling. Extension of canonical thermodynamical model to a projectile fragmentation model is outlined. Application of the projectile fragmentation model for calculating average number of intermediate mass fragments and the average size of the largest cluster at different bound, differential charge distribution and cross-section of neutron-rich nuclei of different projectile fragmentation reactions at different energies are described. Application of nuclear multifragmentation reaction in basic research as well as in other domains is outlined.

    In this study, efforts were made to construct Country Specific Data Base(CSDB) on technology, cost, and environment of energy sources being used in power plant in Korea, referring the structure and contents of the RTDB developed by the DECADES project which is initialed by several international agencies including IAEA . Also, emission coefficients were derived through the plant level analysis of DECPAC. On the energy chain level, the amount of pollutant emission of 500MWe class coal-fired power plant is estimated based on the CSDB and the coefficients. Besides, various estimation methodologies for pollutant emission, such as SOx, NOx, and TSP, are analyzed and compared among those of the Ministry of Environment, KEPCO, and Korea Energy Economic Institute. On the other hand, the amount of pollutant emission stemming from the Korea's electric system as a whole during 1994 and 2006 were estimated on the electric system level. The sensitivity analysis to both capacity factor and plant lifetime was also performed. When the CSDB is improved to cover the full energy chain and includes data base on renewable energy in the future, the CSDB can provide useful information for Korea's electric system expansion planning. 50 tabs., 37 figs., 82 refs.

  3. Basic radiobiology

    International Nuclear Information System (INIS)

    Radiobiology, a branch of science concerned with the action of ionizing radiation on biological tissues and living organisms, is a combination of two disciplines: radiation physics and biology. For use in radiobiology and radiation protection the physical quantity that is useful for defining the quality of an ionizing radiation beam is the linear energy transfer (LET). In contrast to the stopping power, which focuses attention on the energy loss by an energetic charged particle moving through a medium, the LET focuses attention on the linear rate of energy absorption by the absorbing medium as the charged particle traverses the medium. When cells are exposed to ionizing radiation the standard physical effects between radiation and the atoms or molecules of the cells occur first and the possible biological damage to cell functions follows later. The biological effects of radiation result mainly from damage to the DNA, which is the most critical target within the cell; however, there are also other sites in the cell that, when damaged, may lead to cell death

    2007-10-01

    The urban groundwater of the central Besòs river basin (the La Llagosta aquifer) has become contaminated due to the infiltration of wastewater from septic tanks and sewage networks, and by industrial activities located in urban areas. The groundwater hydrogeochemistry of the La Llagosta aquifer was characterized using isoconcentration maps, hydrogeochemical diagrams (Piper, Schoeller-Berkaloff) and by analyzing hydrogeochemical changes along a flow-path that crosses an urban and peripheral industrial area in the main alluvial aquifer (the La Llagosta unit). The evolution of cations, anions and heavy metals along the flow path and the use of the PHREEQC numerical code indicate a complex set of geochemical processes, which result from the interaction between the sources of pollution, the groundwater flow and the mineral composition of the aquifer materials. The contaminated groundwater below the urban areas shows high contents of NO(3)(-) (90-100 mg/L) and an increase in the concentrations of Ca(2+) and Mg(2+) which coincides with a decrease in pH. The Eh shows greater variation than the pH along the flow line studied, with values ranging between 56 mV in the industrial area and 370 mV in the urban area. The area with the lowest Eh value coincides with the highest concentrations of dissolved Fe (4.7 mg/L) and Mn (0.22 mg/L). PMID:17223248

    The increasing awareness of the energy-environment nexus is compelling the development of technologies that reduce environmental impacts during energy production as well as energy consumption during environmental remediation. Countries spend billions in pollution cleanup projects, and new technologies with low energy and chemical consumption are needed for sustainable remediation practice. This perspective review provides a comprehensive summary on the mechanisms of the new bioelectrochemical system (BES) platform technology for efficient and low cost remediation, including petroleum hydrocarbons, chlorinated solvents, perchlorate, azo dyes, and metals, and it also discusses the potential new uses of BES approach for some emerging contaminants remediation, such as CO2 in air and nutrients and micropollutants in water. The unique feature of BES for environmental remediation is the use of electrodes as non-exhaustible electron acceptors, or even donors, for contaminant degradation, which requires minimum energy or chemicals but instead produces sustainable energy for monitoring and other onsite uses. BES provides both oxidation (anode) and reduction (cathode) reactions that integrate microbial-electro-chemical removal mechanisms, so complex contaminants with different characteristics can be removed. We believe the BES platform carries great potential for sustainable remediation and hope this perspective provides background and insights for future research and development. PMID:25886880

    In this study, response surface methodology (RSM) model was applied for optimization of Basic Red 2 (BR2) removal using electrocoagulation/eggshell (ES) coupling process in a batch system. Central composite design was used to evaluate the effects and interactions of process parameters including current density, reaction time, initial pH and ES dosage on the BR2 removal efficiency and energy consumption. The analysis of variance revealed high R(2) values (≥85%) indicating that the predictions of RSM models are adequately applicable for both responses. The optimum conditions when the dye removal efficiency of 93.18% and energy consumption of 0.840 kWh/kg were observed were 11.40 mA/cm(2) current density, 5 min and 3 s reaction time, 6.5 initial pH and 10.91 g/L ES dosage.

    Biovalorization of dark fermentation effluent (DFE) in a microbial fuel cell (MFC) was studied using the biocatalyst enriched from farm manure. The MFC performance was evaluated in terms of power density, substrate degradation, energy conversion efficiency and shifts in system redox state with operation time and organic loading rate (OLR). Higher power density of 165 mW m-2 (12.5 W m-3) was observed at OLR I, which dropped to 86 mW m-2 at OLR II and 39 mW m-2 at OLR III. The substrate degradation was also higher at OLR I (72%) and diminished with increasing the OLR. The pH showed rapid drop and fluctuations initially when shifted to DFE but adapted over time. Higher coulombic efficiency was observed (48% at OLR I) contributing to a total energy conversion of 11%, which is higher compared to the available literature. However, the MFC performance declined at higher OLR with respect to all the performance indicators. DFE consisted of residual sugars from first stage process along with the volatile fatty acids (VFAs) and alcohols, which contributed for the generation of organic acids with their simultaneous consumption and led to VFA increment in spite of COD removal. Cyclic voltammograms along with the derived electro-kinetics supported the observed shifts.

    The need of new energy introduction is found in matters relating to energy security, resources depletion, environmental problems, and the construction of distributed energy sources. The total amount of new energy in the prefecture is 4,859,052Gcal (525,301kl in terms of crude oil), which occupies approximately 30% of the energy that the prefecture demanded in fiscal 1996. Out of the said new energy, those from the sun, wind, ocean, and small- and medium-scale water systems may be acquired in the form of electric power, and they add up to 3,615,424MWh (3,109,265Gcal in terms of calorific value, 336,137kl in terms of crude oil) and occupy 64% (including industrial wastes) of the whole amount. As for the percentage of each type of new energy, solar energy is the highest, its amount of 2,973,679Gcal (321,479kl) occupying 61.2% of the whole, followed by the energy from wastes whose amount in total is 695,131Gcal (75149kl) occupying 14.3%. The possibility of introduction of new energy is studied and the conclusion is described for each energy type, district, and sector (residential and commercial, industrial, transportation). The respects on which prudence should be exercised in introducing new energy are also discussed. (NEDO)

    Information on both hydraulic and thermal conditions of the subsurface is fundamental for the planning and use of hydrothermal energy. This is paramount in particular for densely populated international border regions, where different subsurface applications may introduce conflicts of use and require reliable cross-border management and planning tools. In the framework of the Interreg4a GeoPower project, fundamental geological and geophysical information of importance for the planning of geothermal energy utilization in the Danish-German border region was compiled and analyzed. A 3D geological model was developed and used as structural basis for the set-up of a regional temperature model. In that frame, new reflection seismic data were obtained to close local data gaps in the border region. The analyses and reinterpretation of available relevant data (old and new seismic profiles, core and well-log data, borehole data, literature data) and a new time-depth conversion (new velocity model) allowed correlation of seismic profiles across the border. On this basis, new topologically consistent depth and thickness maps for 12 geological/lithological units were drawn, with special emphasis on potential geothermal reservoirs, and a new 3D structural geological model was developed. The interpretation of petrophysical data (core data and well logs) allows to evaluate the hydraulic and thermal rock properties of geothermal formations and to develop a parameterized 3D thermal conductive subsurface temperature model. New local surface heat-flow values (range: 72-84 mW/m²) were determined and predicted temperature were calibrated and validated by borehole temperature observations. Finally, new temperature maps for major geological sections (e.g. Rhaetian/Gassum, Middle Buntsandstein) and selected constant depth intervals (1 km, 2 km, etc.) were compiled. As an example, modelled temperatures for the Middle Buntsandstein geothermal reservoir are shown with temperatures ranging

    renewable sources of energy include water, sun, and wind. Wind power engineering best fits the conditions of the Russian territories. However, experts believe that the wind power is to be backed by other sources due to the irregularity of its generation. This approach to the power generation and planning of territories coupled with the integration of renewable energy technologies into architectural designs of buildings and structures will make it possible to identify the prerequisites for the energy generation specialization of the subjects of the Russian Federation on the basis of their climatic conditions and urban development patterns. Private investments into renewable sources of energy will assure sustainable population settlement patterns and optimal energy generation and consumption.

    The Basic Energy Science Synchrotron Radiation Center (BESSRC) Collaborative Access Team (CAT) will construct x-ray beamlines at two sectors of the Advanced Photon Source facility. In most of the beamlines the first optical element will be a monochromator, so that a standard design for this critical component is advantageous. The monochromator is a double-crystal, fixed exit scheme with a constant offset designed for ultrahigh vacuum windowless operation. In this design, the crystals are mounted on a turntable with the first crystal at the center of rotation. Mechanical linkages are used to correctly position the second crystal and maintain a constant offset. The main drive for the rotary motion is provided by a vacuum compatible Huber goniometer isolated from the main vacuum chamber. The design of the monochromator is such that it can accommodate water, gallium, or liquid-nitrogen cooling for the crystal optics.

  18. A novel coordinated control strategy considering power smoothing for a hybrid photovoltaic/battery energy storage system

    This work presents a novel coordinated control strategy of a hybrid photovoltaic/battery energy storage (PV/BES) system. Different controller operation modes are simulated considering normal, high fluctuation and emergency conditions. When the system is grid-connected, BES regulates the fluctuated power output which ensures smooth net injected power from the PV/BES system. In islanded operation, BES system is transferred to single master operation during which the frequency and voltage of the islanded microgrid are regulated at the desired level. PSCAD/EMTDC simulation validates the proposed method and obtained favorable results on power set-point tracking strategies with very small deviations of net output power compared to the power set-point. The state-of-charge regulation scheme also very effective with SOC has been regulated between 32% and 79% range.

  19. Evaluation of socio-economic effects of R and D results at Japan Atomic Energy Research Institute. 2. Socio-economic evaluation of the basic research at JAERI

    International Nuclear Information System (INIS)

    The Japan Atomic Energy Research Institute (JAERI), as a core organization devoted to comprehensive nuclear energy research, has steadily promoted various types of research and development (R and D) studies since its establishment in June 1956. Research activities are aimed at performing (1) R and D for nuclear energy, (2) the utilization and application of radiation-based technologies, and (3) the establishment of basic and fundamental research in the nuclear field. Last year, the socio-economic effects on items (1) and (2) were qualitatively and quantitatively evaluated. The quantitative evaluation of item (3) from the viewpoint of a socio-economic effect, however, calls for a different concept and methodology than previously used cost-benefit approach. Achievements obtained from the activities conducted over the last 10 years implied that socio-economics in basic research funded by the public could contribute to the (1) increase in useful intellectual stocks, (2) upbringing of highly skilled college graduates, (3) construction of new scientific facilities and creation of methodologies, (4) stimulation and promotion of social interrelations by networking, (5) increase of one's ability to solve scientific problems, and (6) establishment of venture companies. In this study, we focused on item (4) for the analysis because it assumed that the external economic effect has a link with the socio-economic effects accompanying the networking formation. For the criteria of socio-economic effects we assume that the external effect becomes significant in proportion to the width of networking and/or the magnitude of cooperation measured by numbers of co-writing studies between JAERI and the research bodies, namely private and governmental sectors and universities. Taking these criteria into consideration, the subsequent four items are prepared for quantitative study. They are (1) to clarify the basic research fields where JAERI has been established a significant effort to

    Il paper è incentrato sul dramma musicale Livlægens besøg (2009 del compositore danese Bo Holten, basato sul complesso omonimo bestseller di Per Olov Enquist imperniato sulle vicende del regno danese di Christian VII. Scopo dell’articolo è riuscire a comprendere quale sia la funzione della presenza di Pulcinella nelle scelte registiche della prima messinscena. Per giungere a dei risultati concreti si sono presi in considerazione alcuni studi relativi ai Pulcinella disegnati da Giandomenico Tiepolo, studi nei quali l’iconografia del personaggio comico viene studiata sia da un punto di vista storico-artistico (Bostock sia da un punto di vista prettamente psicologico (Carli. Pulcinella interagisce sull’azione, la maschera gli impedisce la comunicazione mimica del viso ma non quella corporea. La sua funzione è in linea con la lettura psicologica di Carli, secondo la quale Pulcinella rappresenta una sorta di sospensione del giudizio emotivo. Christian è il personaggio che più è legato a Pulcinella, in quanto esso assume un valore metateatrale. Infatti, come emerge dal romanzo di Enquist ma non dal libretto dell’opera, il sovrano era molto attaccato all’arte drammatica e Pulcinella incarna questa sua passione. Pulcinella ha quindi un carattere unificatore all’interno della complessità di Livlægens besøg.

  9. Comparison between regenerative organic Rankine cycle (RORC) and basic organic Rankine cycle (BORC) based on thermoeconomic multi-objective optimization considering exergy efficiency and levelized energy cost (LEC)

    International Nuclear Information System (INIS)

    Highlights: • The thermoeconomic comparison of regenerative RORC and BORC is investigated. • The Pareto frontier solution with bi-objective compares with the corresponding single-objective solutions. • The three-objective optimization of the RORC and BORC is studied. • The RORC owns 8.1% higher exergy efficiency and 21.1% more LEC than the BORC under the Pareto-optimal solution. - Abstract: Based on the thermoeconomic multi-objective optimization by using non-dominated sorting genetic algorithm (NSGA-II), considering both thermodynamic performance and economic factors, the thermoeconomic comparison of regenerative organic Rankine cycles (RORC) and basic organic Rankine cycles (BORC) are investigated. The effects of five key parameters including evaporator outlet temperature, condenser temperature, degree of superheat, pinch point temperature difference and degree of supercooling on the exergy efficiency and levelized energy cost (LEC) are examined. Meanwhile, the Pareto frontier solution with bi-objective for maximizing exergy efficiency and minimizing LEC is obtained and compared with the corresponding single-objective solutions. Research demonstrates that there is a significant negative correlation between thermodynamic performance and economic factors. And the optimum exergy efficiency and LEC for the Pareto-optimal solution of the RORC are 55.97% and 0.142 $/kW h, respectively, which are 8.1% higher exergy efficiency and 21.1% more LEC than that of the BORC under considered condition. Highest exergy and thermal efficiencies are accompanied with lowest net power output and worst economic performance. Furthermore, taking the net power output into account, detailed investigation on the three-objective optimization for maximizing exergy efficiency, maximizing net power output and minimizing LEC is discussed

    Empathy is considered a key construct in the empirical study of high-risk adolescent and young adult delinquency, crime, and violence. This study examined the psychometric properties and criterion-related validity of a Spanish adaptation of the Basic Empathy Scale (BES), which is an important measure designed to capture both affective and cognitive empathy that has been validated in multiple languages but not in Spanish. The study's sample consisted of 208 high-risk and gang-involved adolescents and young adults in the Greater San Salvador Metropolitan Area. The original BES was reduced from its 20-item design to a more culturally appropriate 7-item design. The results of the confirmatory factor analysis and criterion-related validity analysis indicate that the adapted BES is a valid and reliable multidimensional measure of empathy for high-risk Salvadoran adolescents and young adults. Consistent with previous findings, females reported lower levels of empathy than males and delinquent/violent respondents reported lower levels of empathy than their nonoffender counterparts.

    This successful book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing hypersonic cruise and acceleration vehicles. The book gives a review of the issues of transport of momentum, energy and mass, real-gas effects as well as inviscid and viscous flow phenomena. In this second, revised edition the chapters with the classical topics of aerothermodynamics more or less were left untouched. The access to some single topics of practical interest was improved. Auxiliary chapters were put into an appendix. The recent successful flights of the X-43A and the X-51A indicate that the dawn of sustained airbreathing hypersonic flight now has arrived. This proves that the original approach of the book to put emphasis on viscous effects and the aerothermodynamics of radiation-cooled vehicle surfaces was timely. This second, revised edition even more accentuates these topics. A new, additional chapter treats examples of viscous thermal surface eff...

    Renewable gases such as biogas and biomethane are considered as key energy carrier when the society is replacing fossil fuels with renewable alternatives. In Sweden, almost 80 % of the fossil fuels are used in the transport sector. Therefore, the focus in Sweden has been to use the produced biogas in this sector as vehicle gas. Basic Data on Biogas contains an overview of production, utilisation, climate effects etc. of biogas from a Swedish perspective. The purpose is to give an easy overview of the current situation in Sweden for politicians, decision makers and interested public. 1.4 TWh of biogas is produced annually in Sweden at approximately 230 facilities. The 135 wastewater treatment plants that produce biogas contribute with around half of the production. In order to reduce the sludge volume, biogas has been produced at wastewater treatment plants for decades. New biogas plants are mainly co-digestion plants and farm plants. The land filling of organic waste has been banned since 2005, thus the biogas produced in landfills is decreasing.

    Confounded by kinetic energy? Suspect that teaching about simple machines isn t really so simple? Exasperated by electricity? If you fear the study of energy is beyond you, this entertaining book will do more than introduce you to the topic. It will help you actually understand it. At the book s heart are easy-to-grasp explanations of energy basics work, kinetic energy, potential energy, and the transformation of energy and energy as it relates to simple machines, heat energy, temperature, and heat transfer. Irreverent author Bill Robertson suggests activities that bring the basic concepts of energy to life with common household objects. Each chapter ends with a summary and an applications section that uses practical examples such as roller coasters and home heating systems to explain energy transformations and convection cells. The final chapter brings together key concepts in an easy-to-grasp explanation of how electricity is generated. Energy is the second book in the Stop Faking It! series published by NS...

    2012-01-01

    The Beam Energy Scan (BES) program is being pursued at RHIC to study the QCD phase diagram, and search for the possible QCD phase boundary and possible QCD critical point. The data for Phase-I of the BES program have been collected for Au+Au collisions at center-of-mass energies ($\\sqrt{s_{NN}}$) of 7.7, 11.5, 19.6, 27, and 39 GeV. These collision energies allowed the STAR experiment to cover a wide range of baryon chemical potential $\\mu_{B}$ (100--400 MeV) in the QCD phase diagram. We report on several interesting results from the BES Phase-I covering the high net-baryon density region. These results shed light on particle production mechanism and freeze-out conditions, first-order phase transition and "turn-off" of QGP signatures, and existence of a critical point in the phase diagram. Finally, we give an outlook for the future BES Phase-II program and a possible fixed target program at STAR.

    2016-01-01

    We systematically compare an event-by-event transport+viscous hydrodynamics hybrid model to data from the RHIC beam energy scan using a general Bayesian method. We demonstrate how the inclusion of multistrange hadron observables affects the outcome of the Bayesian analysis and conduct an in depth analysis of the viability of $\\phi$ and $\\Omega$ as probes of the transition region between a deconfined quark-gluon plasma and hadronic phase in heavy ion collisions at higher-end RHIC collision energies. Utilizing UrQMD to model the final hadronic interactions, we examine the collision rates of $\\phi$ and $\\Omega$ and the modification to their transverse momentum spectra due to these interactions.

  13. Directed basic research

    International Nuclear Information System (INIS)

    In its execution, and in the requirement of no other deliverables than knowledge generation, directed basic research is no different from conventional (self-directed) basic research. The selected areas are determined in a national perspective. Directed Basic Research may be in an area where the knowledge generation would benefit Indian Society in the long term, or it may be in an area where the results of the research would benefit Indian Industry or our strategic interests in the long term. India can become a global innovation leader provided we have technology foresight to make the right technology choices, provided we introduce coherent synergy (a phrase I coined a few years back in this context) in our science and technology related activities and provided we establish an effective innovation ecosystem. We must also selectively promote some technology areas through directed basic research. Sustainable economic development in the future requires strong and increased funding of basic research. While directed basic research should be encouraged, self-directed basic research should also receive substantially increased support. (author)

    Traeger, R.K.

    1983-12-01

    Extensive quantities of high-quality energy are estimated to be available from molten magma bodies existing within 10 Km of the US continent's surface. A five-year study sponsored by DOE/BES demonstrated that extraction of energy from these melts was scientifically feasible. The next stage of assessment is to evaluate the engineering feasibility of energy extraction and provide a preliminary economic evaluation. Should the second step demonstrate engineering feasibility, the third step would include detailed economic, market and commercialization endeavors. Evaluation of the engineering feasibility will be initiated in FY 84 in a program supported by DOE/GHTD and managed by Dave Allen. The project will be managed by Sandia Labs in James Kelsey's Geothermal Technology Development Division. The project will continue to draw on expertise throughout the country, especially the scientific base established in the previous BES Magma Energy Program.

    The available data on the $D\\overline{D}$ and inclusive hadronic cross section in the $\\psi(3770)$ region from the BaBar, Belle, BES-II, CLEO and KEDR experiments have been analyzed assuming that systematic uncertainties on cross sections measured by different detectors are not correlated. Four theoretical models predicting the $\\psi(3770)$ line shape were considered for the $D\\overline{D}$ channel. All of them gave satisfactory description of the data. The combined analysis of the $D\\overline{D}$ and inclusive hadronic channel was performed using the model based on the vector dominance approach and accounting for the contribution of the $\\psi(2S)$ tail to the $D\\overline{D}$ cross section. The following values of the mass, total width, electron width and decay probability to the non-$D\\overline{D}$ states were obtained: $M=3779.8 \\pm 0.6 ~\\text{MeV}, \\Gamma=25.8 \\pm 1.3 ~\\text{MeV} , \\Gamma_{ee}=196 \\pm 18 ~\\text{eV}, \\mathcal{B}_{nD\\overline{D}}=0.164 \\pm 0.049$, where the errors quoted include both statist...

    The global climate and environmental problems caused by increasing consumption of fossil fuels have greatly accelerated the development of new technologies for clean and sustainable energy based on solar energy. How to harness solar energy and transform it efficiently to energy forms which can be used directly by the mankind has long been the most basic scientific problem of global concern. In the history of science and technology; it is common that imitating the nature often inspires new technologies. For example; inspired by imitating the flight of birds; the mankind has created the aeroplanes within less than a century. The most effective process of harnessing solar energy is the photosynthesis; which has reached its perfection in nature after over 3.5 billion years evolution. Photosynthesis is the most effective process to harness; transport and convert solar energy into chemical energy. Photosynthesis happens in chloroplast where occur a serious of activities; e.g.; harnessing solar energy; splitting water and produce oxygen and carbohydrates. This observation has caused the inspiration that it is possible for the mankind to imitate photosynthesis and to harness and transform solar energy effectively. The article has introduced the principles of how to solve the energy and environmental problems through artificial photosynthesis. Based on these observations; it has discussed the perspective of using the principle of photosynthesis to collect solar energy by means of imitating the process of photosynthesis to produce clean and sustainable energy.%化石能源的大量消耗,以及由此带来的全球气候和环境问题,推动了以太阳能为基础的新型清洁能源的研究.长期以来,如何有效地捕获太阳能,并将其高效率地转化成人类可以直接利用的能源,一直是太阳能利用中最基础的科学问题,得到了全世界的广泛关注.科学技术的发展史说明,人类从认识自然、模仿自然规律开始,已经创

  1. On the scope of the Federal Government to issue orders in plan approval procedures under para. 9b of the Atomic Energy Act as provided by article 85 section 3 of the Basic Law

    International Nuclear Information System (INIS)

    Under Paragraph 9b of the Atomic Energy Act the Lower Saxonian Minister of the Environment has the competence for the plan approval procedure concerning the final disposal site Konrad. The plan approval procedure under atomic energy law is a unitary administrative procedure which makes further administrative procedures and administrative decisions superfluous on the strength of its unitary character and without impingement on constitutional law. In conducting the plan approval procedure the Lower Saxonican Minister of the Environment is acting within the framework of Laender administration on behalf of the Federation. To this extent he is subject to the orders of the Federal Minister of the Enviroment under Article 85 Section 3 of The Basic Law with respect to the formation of the procedure and procedural decisions as well as decisions on the merits pending. The concentrating effect of the plan approval procedure under atomic energy law also extends to permits under water law. (orig./HSCH)

  13. Fluorescence Resonance Energy Transfer (FRET as a method to calculate the dimerization strength of basic Helix-Loop-Helix (bHLH proteins

    Directory of Open Access Journals (Sweden)

    Centonze Victoria E.

    2004-01-01

    Full Text Available Post-translational modifications such as phosphorylation play a vital role in the regulation of protein function. In our study of the basic Helix-loop-Helix (bHLH transcription factor HAND1, we show that HAND1 is phosphorylated during the trophoblast giant cell differentiation on residues residing in Helix I of the bHLH domain. Our hypothesis is that these modifications result in changes in HAND1 dimerization affinities with other bHLH factors. To test this idea, we employed FRET to measure the protein-protein interactions of HAND1 and HAND1 point mutants in HEK293 cells using YFP and CFP fusion proteins and laser scanning confocal microscopy.

    The beam energy measurement system is of great importance and profit for both BEPC-II accelerator and BES-III detector. The system is based on measuring the energies of Compton back-scattered photons. Many advanced techniques and precise instruments are employed to realize the highly accurate measurement of positron/electron beam energy. During five year's running period, in order to meet the requirement of data taking and improve the capacity of measurement itself, the upgradation of system is continued, which involve the component reformation of laser and optics subsystem, replacement of view-port of the laser to vacuum insertion subsystem, the purchase of electric cooling system for high purity germanium detector, and the improvement of data acquisition and processing subsystem. The upgrading of system guarantees the smooth and efficient measuring of beam energy at BEPC-II and accommodates the accurate offline energy values for further physics analysis at BES-III.

    2007-01-01

    Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is uniquely suited to students of materials science. Many competing texts focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves. Professor André Moliton is Director of the Unité de Microélectronique, Optoélectronique et Polymères (Université de Limoges, France), which brings together three groups studying the optoelectronics of molecular and polymer layers, micro-optoelectronic systems for teleco...

    2014-01-01

    The aim of the current research was to study cognitive and affective empathy in children aged 6-12 years old, and their associations with children's family environment and social adjustment. For this purpose, we developed the Spanish version of the Basic Empathy Scale (BES), self- and parent-report forms. Factorial analyses confirmed a two-component model of empathy in both self- and parent-report forms. Concordance between parent-child measures of empathy was low for cognitive and affective factors. Analyses of variance on the cognitive and affective components brought a significant effect of age for self-reported cognitive empathy, with older children scoring higher than younger ones. Gender brought out a significant principal effect for self-reported affective empathy, with girls scoring higher than boys. No other main effects were found for age and gender for the rest of the factors analyzed. Children's empathy was associated with socioeconomic status and other family socialization processes, as well as children' social behaviors. Overall the new measures provided a coherent view of empathy in middle childhood and early adolescence when measured through self and parent reports, and illustrate the similarity of the validity of the BES in a European-Spanish culture.

    2016-01-12

    Here we explored the performance of Hartree-Fock (HF), Perdew-Burke-Ernzerhof (PBE), and Tao-Perdew-Staroverov-Scuseria (TPSS) functionals in predicting core level 1s binding energies (BEs) and BE shifts (ΔBEs) for a large set of 68 molecules containing a wide variety of functional groups for main group elements B → F and considering up to 185 core levels. A statistical analysis comparing with X-ray photoelectron spectroscopy (XPS) experiments shows that BEs estimations are very accurate, TPSS exhibiting the best performance. Considering ΔBEs, the three methods yield very similar and excellent results, with mean absolute deviations of ∼0.25 eV. When considering relativistic effects, BEs deviations drop approaching experimental values. So, the largest mean percentage deviation is of 0.25% only. Linear trends among experimental and estimated values have been found, gaining offsets with respect to ideality. By adding relativistic effects to offsets, HF and TPSS methods underestimate experimental values by solely 0.11 and 0.05 eV, respectively, well within XPS chemical precision. TPSS is posed as an excellent choice for the characterization, by XPS, of molecules on metal solid substrates, given its suitability in describing metal substrates bonds and atomic and/or molecular orbitals.

    2009-10-15

    The aim of the project was to provide a basis for the revision of the so-called 'Efficiency Path' of the Swiss Association of Engineers and Architects (SIA) in the context of the goals of the 2000-Watt-Society. Particularly, the objective is to find the conditions in which the specific goals of the 2000-Watt-Society for residential, school and office buildings could be reached. Considered indicators are the per capita primary energy use in terms of average power and the greenhouse gas emissions. A bottom-up model was developed to estimate final and primary energy demand of the mentioned building types, broken down by different types of energy utilisation. Assumptions were made regarding the most important physical drivers as well as for regarding energy efficiency parameters of new buildings, building retrofits, building technologies and other energy applications in the residential, school and office buildings. Two basic scenarios were developed: an ambitious efficiency scenario was compared to a reference scenario which included current and foreseeable energy policy elements. Regarding electricity supply three scenario-variants of the so-called Swiss Energy Perspectives of the Swiss Federal Office of Energy (SFOE) were used: variant I b 'business-as-usual - nuclear and central fossil plants', IV a: Path to the 2000-Watt-Society - nuclear' and, IV e 'Path to the 2000-Watt-Society - renewable energies'. With this respect it was found that in the case of the efficiency scenario the influence of the electricity generation mix is relatively small. This finding is explained by the fact that hydro power (which is held more or less at the current level) has a large share in the power supply mix in the case of the efficiency scenario with moderate electricity demand and that hydro power is efficient in terms of primary energy and has considerably low greenhouse gas emissions. The results of the study show that with the underlying

    Gallo, A

    2011-01-01

    RF electronics deals with the generation, acquisition and manipulation of high-frequency signals. In particle accelerators signals of this kind are abundant, especially in the RF and beam diagnostics systems. In modern machines the complexity of the electronics assemblies dedicated to RF manipulation, beam diagnostics, and feedbacks is continuously increasing, following the demands for improvement of accelerator performance. However, these systems, and in particular their front-ends and back-ends, still rely on well-established basic hardware components and techniques, while down-converted and acquired signals are digitally processed exploiting the rapidly growing computational capability offered by the available technology. This lecture reviews the operational principles of the basic building blocks used for the treatment of high-frequency signals. Devices such as mixers, phase and amplitude detectors, modulators, filters, switches, directional couplers, oscillators, amplifiers, attenuators, and others are d...

  1. Basic linear algebra

    CERN Document Server

    Blyth, T S

    2002-01-01

    Basic Linear Algebra is a text for first year students leading from concrete examples to abstract theorems, via tutorial-type exercises. More exercises (of the kind a student may expect in examination papers) are grouped at the end of each section. The book covers the most important basics of any first course on linear algebra, explaining the algebra of matrices with applications to analytic geometry, systems of linear equations, difference equations and complex numbers. Linear equations are treated via Hermite normal forms which provides a successful and concrete explanation of the notion of linear independence. Another important highlight is the connection between linear mappings and matrices leading to the change of basis theorem which opens the door to the notion of similarity. This new and revised edition features additional exercises and coverage of Cramer's rule (omitted from the first edition). However, it is the new, extra chapter on computer assistance that will be of particular interest to readers:...

  2. Basic electronic circuits

    Buckley, P M

    1980-01-01

    In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli­ cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encounte...

    Statistics links microscopic and macroscopic phenomena, and requires for this reason a large number of microscopic elements like atoms. The results are values of maximum probability or of averaging. This introduction to statistical physics concentrates on the basic principles, and attempts to explain these in simple terms supplemented by numerous examples. These basic principles include the difference between classical and quantum statistics, a priori probabilities as related to degeneracies, the vital aspect of indistinguishability as compared with distinguishability in classical physics, the differences between conserved and non-conserved elements, the different ways of counting arrangements in the three statistics (Maxwell-Boltzmann, Fermi-Dirac, Bose-Einstein), the difference between maximization of the number of arrangements of elements, and averaging in the Darwin-Fowler method. Significant applications to solids, radiation and electrons in metals are treated in separate chapters, as well as Bose-Eins...

    Full Text Available The patterns of residential installation of the new foreign immigration, the patterns of implementation of businesses run by immigrant entrepreneurs, as well as certain uses of private and public space and mobility to and from the neighborhood of el Besòs i el Maresme are contemplated in this paper. The lived space by the foreign immigrants contains elements of urban change that are added to the urban dynamics promoted by the public governments. El Besòs i el Maresme not only allows for the assessment of trends common to many Spanish popular neighborhoods that meet now the same stage of development, but it also offers a possibility of analysis in terms of urban revitalization by its location in the immediate vicinity of the largest space of urban change in the northeast of the Catalan capital, although the contradictory processes at work that point to the social marginalization are not ignored. This text is based on fieldwork done by the authors in 2007-2009.En este trabajo se observan las pautas de la instalación residencial de la nueva inmigración extranjera, los patrones de implantación de comercios regentados por emprendedores inmigrantes, así como ciertos usos del espacio privado y público y la movilidad en y desde el barrio de el Besòs i el Maresme. El espacio vivido por los extranjeros contiene elementos de cambio urbano que se añaden a las dinámicas urbanísticas impulsadas desde las administraciones públicas. El Besòs i el Maresme permite no solo evaluar tendencias comunes a muchos barrios populares españoles que conocen actualmente la misma etapa de desarrollo, sino que también ofrece una posibilidad de análisis en términos de revitalización urbana por su localización en el entorno inmediato del mayor espacio de cambio urbanístico en el nordeste de la capital catalana, aunque no se ignoran en el trabajo procesos contradictorios que apuntan hacia la marginación social.

    For prevention of global warming by greenhouse effect gas, study was made on energy saving measures for Achinsk refinery in Russia. Achinsk refinery is a relatively new plant put into operation in 1983, however, because of no various equipment for use combustion heat effectively, its average thermal efficiency is as low as 60%-70%, resulting in fuel consumption more than necessary one. Based on the study result, the following remodeling designs were made: Improvement of a heat exchange efficiency by relocation of heat exchangers to reduce fuel consumption of a heating furnace as much as possible, conversion of an existing heating furnace based on an old design concept to an advanced one, installation of a waste heat recovery system including a preheating convection unit and air preheater, reinforcement of heating furnace wall insulator, installation of an optimum control system for furnace operation, and improvement of a fuel supply system efficiency. This design showed possible reduction of heating furnace load, and possible furnace thermal efficiency of 90%. (NEDO)

  14. Technical and economic design of photovoltaic and battery energy storage system

    International Nuclear Information System (INIS)

    Highlights: • Design of grid connected photovoltaic system integrating battery energy storage system. • A model to manage the energy flows and assess the system profitability is presented. • The model evaluates the effective PV power rate and battery energy system capacity. • An application and multi-scenario analysis based on an Italian context is discussed. • Results show the system technical feasibility and an energy cost save of 52 €/MW h. - Abstract: In the last years, the technological development and the increasing market competitiveness of renewable energy systems, like solar and wind energy power plants, create favorable conditions to the switch of the electricity generation from large centralized facilities to small decentralized energy systems. The distributed electricity generation is a suitable option for a sustainable development thanks to the environmental impact reduction, the load management benefits and the opportunity to provide electricity to remote areas. Despite the current cut off of the national supporting policies to the renewables, the photovoltaic (PV) systems still find profitable conditions for the grid connected users when the produced energy is self-consumed. Due to the intermittent and random nature of the solar source, PV plants require the adoption of an energy storage system to compensate fluctuations and to meet the energy demand during the night hours. This paper presents a technical and economic model for the design of a grid connected PV plant with battery energy storage (BES) system, in which the electricity demand is satisfied through the PV–BES system and the national grid, as the backup source. The aim is to present the PV–BES system design and management strategy and to discuss the analytical model to determine the PV system rated power and the BES system capacity able to minimize the Levelized Cost of the Electricity (LCOE). The proposed model considers the hourly energy demand profile for a reference

    We investigate how the properties of dark energy affect the cosmological measurements of neutrino mass and extra relativistic degrees of freedom. We limit ourselves to the most basic extensions of $\\Lambda$CDM model, i.e., the $w$CDM model with one additional parameter $w$, and the $w_{0}w_{a}$CDM model with two additional parameters, $w_{0}$ and $w_{a}$. In the cosmological fits, we employ the 2015 CMB temperature and polarization data from the Planck mission, in combination with low-redshift measurements such as the baryon acoustic oscillations (BAO), type Ia supernovae (SN) and the Hubble constant ($H_{0}$). Given effects of massive neutrinos on large-scale structure, we further include weak lensing (WL), redshift space distortion (RSD), Sunyaev-Zeldovich cluster counts (SZ), and Planck lensing data. We find that $w$ is anti-correlated with $\\sum m_{\

    Cross-sections for one- and multinucleon transfer reactions, namely, 58Ni(12C, 13C), 58Ni(12C, 11C), 58Ni(12C, 11B), 58Ni(12C, 10B), 58Ni(12C, 10Be), 58Ni(12C, 9Be), 58Ni(12C, 8Be.s.), 58Ni(12C, 7Be), 58Ni(12C, 7Li) and 58Ni(12C, 6Li) have been measured at an incident energy of 60 MeV. The reaction cross-section for the corresponding transfer channels in the system 12C+56Fe have also been measured under the same kinematical conditions. Angular distribution of the elastic scattering cross-section is measured at 60 MeV. The measured elastic scattering angular distributions for these two systems have been analysed using the optical model search code SFRESCO and the potential parameters are extracted. The multinucleon transfer data are analysed to obtain cross-section dependence on the number of nucleons transferred and on the ground state -values. The transfer probabilities for multinucleon stripping are extracted. A detailed comparison in the multiparticle stripping and elastic scattering cross-sections between these two systems are made to understand the mechanism of multinucleon transfer and possible role of two extra protons in 58Ni target nucleus as compared to the 56Fe core.

    2007-10-01

    Full Text Available Currently Indonesia is the world largest palm oil producer with production volume reaching 16 million tones per annum. The high crude oil and ethylene prices in the last 3 – 4 years contribute to the healthy demand growth for basic oleochemicals: fatty acids and fatty alcohols. Oleochemicals are starting to replace crude oil derived products in various applications. As widely practiced in petrochemical industry, catalyst plays a very important role in the production of basic oleochemicals. Catalytic reactions are abound in the production of oleochemicals: Nickel based catalysts are used in the hydrogenation of unsaturated fatty acids; sodium methylate catalyst in the transesterification of triglycerides; sulfonic based polystyrene resin catalyst in esterification of fatty acids; and copper chromite/copper zinc catalyst in the high pressure hydrogenation of methyl esters or fatty acids to produce fatty alcohols. To maintain long catalyst life, it is crucial to ensure the absence of catalyst poisons and inhibitors in the feed. The preparation methods of nickel and copper chromite catalysts are as follows: precipitation, filtration, drying, and calcinations. Sodium methylate is derived from direct reaction of sodium metal and methanol under inert gas. The sulfonic based polystyrene resin is derived from sulfonation of polystyrene crosslinked with di-vinyl-benzene. © 2007 BCREC UNDIP.

  8. Beam Energy Scan at RHIC and z-Scaling

    International Nuclear Information System (INIS)

    Beam Energy Scan (BES) data obtained at RHIC are briefly reviewed. Method of data analysis (z-scaling approach) based on self-similarity and locality of constituent interactions in hadron and nucleus collisions at high energy is described. The method is applied for analysis of BES data to search for signatures of phase transition and Critical Point (CP). Some results of analysis of hadron spectra measured in heavy ion collisions (HIC) at RHIC over a wide range of the energy √(sNN)=7.7–200 GeV are presented. Microscopic scenario of constituent interactions in the framework of this approach is discussed. Dependence of the energy loss on the momentum of the produced hadron, energy and centrality of the collision is studied. Self-similarity of the constituent interactions in terms of momentum fractions is used to characterize the nuclear medium by a “specific heat” and the colliding nuclei by fractal dimensions. Kinematic regions which are assumed to be most preferable for search for signatures of phase transition of nuclear matter produced in HIC in BES are discussed

    Energy Technology Data Exchange (ETDEWEB)

    1991-08-01

    DOE-2 provides the building design and research communities with an up-to-date, unbiased, well-documented public-domain computer program for building energy analysis. DOE-2 predicts the hourly energy use and energy cost of a building given hourly weather information and a description of the building and its HVAC equipment and utility rate structure. DOE-2 is a portable FORTRAN program that can be used on a large variety of computers, including PC`s. Using DOE-2, designers can determine the choice of building parameters that improve energy efficiency while maintaining thermal comfort. The purpose of DOE-2 is to aid in the analysis of energy usage in buildings; it is not intended to be the sole source of information relied upon for the design of buildings. The judgment and experience of the architect/engineer still remain the most important elements of building design.

    2003-01-01

    Progress in immunology continues to grow exponentially every year. New applications of this knowledge are being developed for a broad range of clinical conditions. Conversely, the study of primary and secondary immunodeficiencies is helping to elucidate the intricate mechanisms of the immune system. We have selected a few of the most significant contributions to the fields of basic and clinical immunology published between October 2001 and October 2002. Our choice of topics in basic immunology included the description of T-bet as a determinant factor for T(H)1 differentiation, the role of the activation-induced cytosine deaminase gene in B-cell development, the characterization of CD4(+)CD25(+) regulatory T cells, and the use of dynamic imaging to study MHC class II transport and T-cell and dendritic cell membrane interactions. Articles related to clinical immunology that were selected for review include the description of immunodeficiency caused by caspase 8 deficiency; a case series report on X-linked agammaglobulinemia; the mechanism of action, efficacy, and complications of intravenous immunoglobulin; mechanisms of autoimmunity diseases; and advances in HIV pathogenesis and vaccine development. We also reviewed two articles that explore the possible alterations of the immune system caused by spaceflights, a new field with increasing importance as human space expeditions become a reality in the 21st century.

    Stefanita, Carmen-Gabriela

    2012-01-01

    This textbook is aimed at engineering students who are likely to come across magnetics applications in their professional practice. Whether designing lithography equipment containing ferromagnetic brushes, or detecting defects in aeronautics, some basic knowledge of 21st century magnetism is needed. From the magnetic tape on the pocket credit card to the read head in a personal computer, people run into magnetism in many products. Furthermore, in a variety of disciplines tools of the trade exploit magnetic principles, and many interdisciplinary laboratory research areas cross paths with magnetic phenomena that may seem mysterious to the untrained mind. Therefore, this course offers a broad coverage of magnetism topics encountered more often in this millenium, revealing key concepts on which many practical applications rest. Some traditional subjects in magnetism are discussed in the first half of the book, followed by areas likely to spark the curiosity of those more interested in today’s technological achi...

    Die Entscheidung, einen zeit- bzw. ereignisgesteuerten Ansatz für ein Echtzeitsystem zu verwenden, ist schwierig und sehr weitreichend. Weitreichend vor allem deshalb, weil diese beiden Ansätze mit äußerst unterschiedlichen Kontrollflussabstraktionen verknüpft sind, die eine spätere Migration zum anderen Paradigma sehr schwer oder gar unmöglich machen. Wir schlagen daher die Verwendung einer Zwischendarstellung vor, die unabhängig von der jeweils verwendeten Kontrollflussabstraktion ist. Für diesen Zweck verwenden wir auf Basisblöcken basierende Atomic Basic Blocks (ABB) und bauen darauf ein Werkzeug, den Real-Time Systems Compiler (RTSC) auf, der die Migration zwischen zeit- und ereignisgesteuerten Systemen unterstützt.

    The enthalpies of proton ionization of the biochemical buffers N,N-bis[2-hydroxyethyl]-2-aminoethanesulfonic acid (BES) and N-tris[hydroxymethyl]methyl-2-aminoethanesulfonic acid (TES) were obtained in water-methanol mixtures in which the methanol mole fraction (X{sub m}) varied in the range 0-0.36. For both buffers, ionization enthalpy for the first proton ({delta}H{sub 1}) was small in all solvent media. However, upon addition of methanol, {delta}H{sub 2} increased steadily from 22.2 to a maximum of 27.2 kJ mol{sup -1} for BES, whereas for TES it varied from 30.0 to 32.4, with a minimum of 28.6 kJ mol{sup -1} at X{sub m}=0.123. It is noteworthy that this solvent composition lies within the region of maximum structure enhancement of water by methanol. The results were interpreted in terms of methanol-water interactions.

  3. Future of the Beam Energy Scan program at RHIC

    International Nuclear Information System (INIS)

    The first exploratory phase of a very successful Beam Energy Scan Program at RHIC was completed in 2014 with Au+Au collisions at energies ranging from 7 to 39 GeV. Data sets taken earlier extended the upper limit of energy range to the √sNN of 200 GeV. This provided an initial look into the uncharted territory of the QCD phase diagram, which is considered to be the single most important graph of our field. The main results from BES phase I, although effected by large statistical errors (steeply increasing with decreasing energy), suggest that the highest potential for discovery of the QCD Critical Point lies bellow √sNN 20 GeV. Here, we discuss the plans and the preparation for phase II of the BES program, with an order of magnitude larger statistics, which is planned for 2018-2019. The BES II will focus on Au+Au collisions at √sNN from 20 to 7 GeV in collider mode, and from √sNN 7 to 3.5 GeV in the fixed target mode, which will be run concurrently with the collider mode operation

    This novel approach to the foundation of the physical theory begins with thought experiments on measurement practice like Einstein for relativistic Kinematics. For a similar foundation of Dynamics one can start from Hermann von Helmholtz analysis of basic measurements. We define energy, momentum and mass from elemental ordering relations for "capability to execute work" and "impact" in a collision and apply Helmholtz program for quantification. From simple pre-theoretic (principle of inertia, impossibility of Perpetuum Mobile, relativity principle) and measurement methodical principles we derive all fundamental equations of Mechanics. We explain the mathematical formalism from the operationalization of basic observables.

    The energy dependence of various particle ratios is calculated within the Ultra-Relativistic Quantum Molecular Dynamics approach and compared with the hadron resonance gas (HRG) model and measurements from various experiments, including RHIC-BES, SPS and AGS. It is found that the UrQMD particle ratios agree well with the experimental results at the RHIC-BES energies. Thus, we have utilized UrQMD in simulating particle ratios at other beam energies down to 3 GeV, which will be accessed at NICA and FAIR future facilities. We observe that the particle ratios for crossover and first-order phase transition, implemented in the hybrid UrQMD v3.4, are nearly indistinguishable, especially at low energies (at large baryon chemical potentials or high density).

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction .

We begin with a chapter on the geometry of Hilbert space and then proceed to the spectral theory of compact self adjoint operators; operational calculus is next presented as a nat­ ural outgrowth of the spectral theory. The second part of the text concentrates on Banach spaces and linear operators acting on these spaces. It includes, for example, the three 'basic principles of linear analysis and the Riesz­ Fredholm theory of compact operators. Both parts contain plenty of applications. All chapters deal exclusively with linear problems, except for the last chapter which is an introduction to the theory of nonlinear operators. In addition to the standard topics in functional anal­ ysis, we have presented relatively recent results which appear, for example, in Chapter VII. In general, in writ­ ing this book, the authors were strongly influenced by re­ cent developments in operator theory which affected the choice of topics, proofs and exercises. One ...

    Full Text Available The goal of grounded theory is to generate a theory that accounts for a pattern of behavior that is relevant and problematic for those involved. The goal is not voluminous description, nor clever verification. As with all grounded theory, the generation of a basic social process (BSP theory occurs around a core category. While a core category is always present in a grounded research study, a BSP may not be.BSPs are ideally suited to generation by grounded theory from qualitative research because qualitative research can pick up process through fieldwork that continues over a period of time. BSPs are a delight to discover and formulate since they give so much movement and scope to the analyst’s perception of the data. BSPs such as cultivating, defaulting, centering, highlighting or becoming, give the feeling of process, change and movement over time. They also have clear, amazing general implications; so much so, that it is hard to contain them within the confines of a single substantive study. The tendency is to refer to them as a formal theory without the necessary comparative development of formal theory. They are labeled by a “gerund”(“ing” which both stimulates their generation and the tendency to over-generalize them.

    In an effort to educate the public about the long road from obscure experiment to life-changing discovery, the National Academy of Sciences (NAS) has been enlisting prominent researchers, science writers, and scientific organizations such as the AGU. More than two years in development, the NAS basic science initiative “Beyond Discovery: The Path From Research to Human Benefits” is an attempt to translate peer-review-quality science papers into general-interest science articles and booklets.As conceived by NAS vice-president Jack Halpern and a host of representatives from the scientific community, the Beyond Discovery initiative will “develop case studies that identify and trace the origins of important technological and medical advances.” These case studies will be written by scientists in a style publishable in a journal such as the Proceedings of the National Academy of Science. The articles are intended to be understandable to educators, college students, and the scientifically literate public. The case studies then will be further distilled by science writers into articles for a wider audience of policy makers and the general public.

    Full Text Available The aim of the current research was to study cognitive and affective empathy in children aged 6 to 12 years old, and their associations with children’s family environment and social adjustment. For this purpose, we developed the Spanish version of the Basic Empathy Scale (BES, self- and parent-report forms. Factorial analyses confirmed a two-component model of empathy in both self- and parent-report forms. Concordance between parent-child measures of empathy was low for cognitive and affective factors. Analyses of variance on the cognitive and affective components brought a significant effect of age for self-reported Cognitive Empathy, with older children scoring higher than younger ones. Gender brought out a significant principal effect for self-reported Affective Empathy, with girls scoring higher than boys. No other main effects were found for age and gender for the rest of the factors analyzed. Children’s empathy was associated with socioeconomic status and other family socialization processes, as well as children’ social behaviors. Overall the new measures provided a coherent view of empathy in middle childhood and early adolescence when measured through self and parent reports, and illustrate the similarity of the validity of the BES in a European-Spanish culture.

    The activities implemented jointly (AIJ) is expected as global measures to reduce greenhouse gas (such as CO2) emission. In this report, the possibility of AIJ projects in developing countries was researched. The United Nations Framework Convention on Climate Change was signed by 155 countries in 1992. This convention parties approved AIJ projects for measures against global warming. The 1st Conference of the Parties (COPI) held in 1995 approved the pilot phase of AIJ by voluntary workers jointly with developing countries until the end of this century. The trend, level and future plan of energy conservation technologies were researched and analyzed for steelmaking, cement and electric power supply industries in both the Philippine and Thailand. The possibility of AIJ projects was studied by selecting several Japanese energy conservation technologies transferable to both countries. The same research was also carried out for forest as carbon absorption source. 5 refs., 23 figs., 58 tabs.

    The ongoing improvement of production technologies has enabled access to unconventional gas resources present in source rocks. Whether Poland is going to see a gas revolution depends chiefly on the geological conditions. At this point it is difficult to estimate the actual size of Poland's shale gas resources and commercialization of shale gas production. First results will be known in the next four or five years, when operators complete the work under exploration and appraisal licences granted to them by the Ministry of the Environment. Polish government is offering licences on exceptionally favourable terms as an incentive for research on unconventional gas resources. Such an approach is driven by the strategic objective of ending Poland's reliance on foreign sources of natural gas in the future. Shale gas will not change Poland's and the region's energy landscape instantaneously. As in the case of all commodity and energy revolutions, changes occur slowly, but shale gas development offers huge opportunities for a permanent shift in the Polish and European energy sectors. Poland stands a chance of becoming fully independent on natural gas imports, and Polish companies - a chance of improving their international standing.

    Full Text Available Velocity dispersed ion signatures (VDIS occurring at the plasma sheet boundary layer (PSBL are a well reported feature. Theory has, however, predicted the existence of multiple ion beamlets, similar to VDIS, in the boundary plasma sheet (BPS, i.e. at latitudes below the PSBL. In this study we show evidence for the multiple ion beamlets in Polar/TIMAS ion data and basic properties of the ion beamlets will be presented. Statistics of the occurrence frequency of ion multiple beamlets show that they are most common in the midnight MLT sector and for altitudes above 4 RE, while at low altitude (≤3 RE, single beamlets at PSBL (VDIS are more common. Distribution functions of ion beamlets in velocity space have recently been shown to correspond to 3-dimensional hollow spheres, containing a large amount of free energy. We also study correlation with ~100 Hz waves and electron anisotropies and consider the possibility that ion beamlets correspond to stable auroral arcs.

    Field research was made for oil saving in Thailand. To promote energy saving in a textile industry as main export industry, its motivation for production stuff is essential in business improvement. Proposal for work improvement, supply system of bonuses, and small-group activity are effective. Management of an energy consumption rate is essential in business management. Use of efficient waste water treatment equipment is also one of the issues. In food factories, various scopes for improvement are still found by mass/heat balance analysis in production process. As an example, a large amount of water is consumed in vain for washing raw rice in a rice powder factory, and separation of SS precipitate from waste water should be improved. Because of lagoon treatment, an effluent standard is not achieved in spite of consumption of wasteful aeration power. This treatment is reasonable because of its scale and site, although the standard can be achieved by activated sludge method. Reconsideration of the standard is also necessary based on a local total BOD load capacity. The profitability of a methane fermentation method should be examined. 72 figs., 95 tabs.

    1991-01-01

    Unlike a conventional microwave tube, a virtual-cathode device operates above the space-charge limit where the depth of the space-charge potential can cause electron reflection. The region associated with this electron reflection is referred to as a virtual cathode. Microwaves can be generated through oscillations in the position of the virtual cathode and through the bunching of electrons trapped in a potential well between the real and virtual cathodes. These two mechanisms are competitive. There are three basic classes of virtual cathode devices: (1) reflex triode; (2) reditron and side-shoot vircator; and (3) reflex diode or vircator. The reflex diode is the highest power virtual-cathode device. For the reflex diode the energy exchange between the beam and electromagnetic wave occurs in both the axial and radial directions. In some designs the oscillating-virtual-cathode frequency exceeds the reflexing-electron frequency exceeds the oscillating-virtual-cathode frequency. For the flex diode a periodic disruption in magnetic insulation can modulate the high- frequency microwave power. Overall, particle-in-cell simulation predictions and axial reflex diode experiments are in good agreement. Although frequency stability and phase locking of the reflex diode have been demonstrated, little progress has been made in efficiency enhancement. 58 refs., 11 figs.

On the basis of security, steady energy supply is of the first priority. In terms of energy structure,there is a need to build a flexible and diversified structure of energy supply and demand,with both coal and nuclear power holding equally vital strategic positions. At present,coal is the principal energy and the important industrial raw material in China,and the“coal dominant”energy structure is under various questions and challenges. In a wave of energy revolution,the energy development in China can draw lessons from Japan’s fourth basic energy plan,in order to make new exploration in aspects of energy positioning,development direction,policies and measures. When actively realizing diversification of energy structure,we must also avoid extensive coal mine exploitation and utilization by innovating the exploitation,utilization and management of coal mines. Meanwhile,we should

    The present thesis deals with two experiments, which perform on the field of the hadron spectroscopy fundamental research. These are the existing BES III experiment, from which data from charmonium decay are analyzed and the future PANDA experiment, for which in this thesis the readout of the forward end cap of the electromagnetic calorimeter is developed. In the first part the radiative decays of ψ(2S) and J/ψ into γ(π{sup +}π{sup -}η) are analyzed for the study of the η(1405) meson. This state is considered as possible glueball candidate, because among others the pseudoscalar-meson nonet with the η(1405), η(1295), and η(1475) is overoccupied by one particle and other experiments assign to the η(1405) a large gluonic contribution. The production of the η(1475) can, as confirmed by other experiments, ot be observed in the decay into π{sup +}π{sup -}η.The η(1295) however is identified in the framework of a partial-wave analysis in the decay J/ψ→γπ{sup +}π{sup -}η. This succeeded previously only in the DM2 experiment, indeed with distinctly lower statistics and corresponding uncertainties. A possible solution of the problem of the overoccupation, the non-existence of the η(1295), cannot be confirmed by the results presented in this thesis. Furthermore the branching ratios of different decays are determined. The high event-rate allows to determine some decay probabilities for the first time respectively clearly more precisely. The partial waves contributing in the decay J/ψ→γπ{sup +}π{sup -}η can be determined by a mass-independent partial-wave analysis and brought into connection with known resonances. In the second part of the thesis the development and optimization of the photodetector-preamplifier units used for the readout of the forward end cap of the electromagnetic calorimeter are shown. A manifold of these detector-units were produced for a prototype of the forward end cap and tested in subsequent test-beam times under real

    With an objective to save energy and reduce greenhouse gas emission, a project has been discussed to introduce a gas turbine combined cycle power generation system for effective waste heat utilization and a pellet coating facility into the direct reduction steel making plant of Ahwaz Steel Complex in the Islamic Republic of Iran. The project will have a waste heat boiler installed at the outlet of the MIDREX plant waste heat recovery device to link it with a gas turbine combined cycle power plant to structure a 42-MW power generation system. In addition, productivity enhancement was attempted by applying the raw material pellets with coating to raise the reduction gas blow-in temperature. The energy saving effect expected from this project would be saving of 63,140 tons of crude oil equivalent annually, and the greenhouse effect gas reducing effect would reduce 173,790 t-CO2 annually. Although the investment will require about 3.16 billion yen, the cost reduction amount in association with power generation is small because of the power purchase unit cost being as very low as 1.9 yen/kWh, making the investment recovery period 10.2 years. Therefore, the project will not be realizable economically. (NEDO)

    1983-09-01

    The original derivation of the basic theory governing the aerodynamics of both hovercraft and modern floatation ovens, requires the validity of some extremely crude assumptions. However, the basic theory is surprisingly accurate. It is shown that this accuracy occurs because the final expression of the basic theory can be derived by approximating the full Navier-Stokes equations in a manner that clearly shows the limitations of the theory. These limitations are used in discussing the relatively small discrepancies between the theory and experiment, which may not be significant for practical purposes.

    Based on the latest version of designing codes both for buildings and bridges (GB50010-2010 and JTG D62-2004), this book starts from steel and concrete materials, whose properties are very important to the mechanical behavior of concrete structural members. Step by step, analysis of reinforced and prestressed concrete members under basic loading types (tension, compression, flexure, shearing and torsion) and environmental actions are introduced. The characteristic of the book that distinguishes it from other textbooks on concrete structures is that more emphasis has been laid on the basic theories of reinforced concrete and the application of the basic theories in design of new structures and analysis of existing structures. Examples and problems in each chapter are carefully designed to cover every important knowledge point. As a basic course for undergraduates majoring in civil engineering, this course is different from either the previously learnt mechanics courses or the design courses to be learnt. Compa...

    The outline of a model for architectural systematization of natural energy conversion and the experiment result on the basic thermal performance in winter are described. The model is about 20 m{sup 2} in floor space. Foam polystyrene of 100 mm and 200 mm thick was used for the outer wall as heat insulating materials. The model has a solar battery and air conditioner and uses red brick as a heat reservoir. An experiment was made on seven modes obtained when three elements (heating, heat storage, and night insulated door) are combined. The information obtained by the experiment showed that a model for architectural systematization has high heat insulation and tightness and can be used as an energy element or an evaluation model for architectural systematization. In this model for architectural systematization, the power consumption of an air conditioner in winter can be fully supplied by only the power generation based on a solar battery. In an architectural element, the heating energy consumption can be remarkably reduced and the indoor thermal environment can be greatly improved, by the combination of a heat reservoir and night heat insulated door. 1 ref., 6 figs., 3 tabs.

    Davies, M. J.; Wood, D. H.

    1983-09-01

    It is pointed out that the basic aerodynamics of modern floatation ovens, in which the continuous, freshly painted metal strip is floated, dried, and cured, is the two-dimensional analog of that of hovercraft. The basic theory for the static lift considered in connection with the study of hovercraft has had spectacular success in describing the experimental results. This appears surprising in view of the crudity of the theory. The present investigation represents an attempt to explore the reasons for this success. An outline of the basic theory is presented and an approach is shown for deriving the resulting expressions for the lift from the full Navier-Stokes equations in a manner that clearly indicates the limitations on the validity of the expressions. Attention is given to the generally good agreement between the theory and the axisymmetric (about the centerline) results reported by Jaumotte and Kiedrzynski (1965).

    The first phase of Beam Energy Scan (BES) program at the Relativistic Heavy-Ion Collider (RHIC) was started in the year 2010 with the aim to study the several aspects of the quantum chromodynamics (QCD) phase diagram. The Solenoidal Tracker At RHIC (STAR) detector has taken data at $\\sqrt{s_{NN}} = $ 7.7, 11.5, 19.6, 27, and 39 GeV in Au+Au collisions in the years 2010 and 2011 as part of the BES programme. For these beam energies, we present the results on the particle yields, average transverse mass and particle ratios for identified particles in mid-rapidity ($|y|$ < 0.1). The measured particle ratios have been used to study the chemical freeze-out dynamics within the framework of a statistical model.

    2006-01-01

    Focusing on the archetypes of linear partial differential equations, this text for upper-level undergraduates and graduate students features most of the basic classical results. The methods, however, are decidedly nontraditional: in practically every instance, they tend toward a high level of abstraction. This approach recalls classical material to contemporary analysts in a language they can understand, as well as exploiting the field's wealth of examples as an introduction to modern theories.The four-part treatment covers the basic examples of linear partial differential equations and their

    Particle physics is the study of the fundamental particles and their fundamental interactions.These fundamental particles are six quarks (u, d, s, c, b and t)and six leptons (e, ve, μ, vμ, τ, vτ) which serve as the blocks for building up the matter in the universe.The elementary theory of the particle physics - the Standard Model (SM)includes both the electroweak theories and the quantum chromodynamics (QCD).Breakthroughs in the electroweak theories have been awarded by three Nobel Prizes, and the QCD has been also honored with the Nobel Prize for its prediction about the particle interaction at high energy.However, the lattice QCD (LQCD) and other QCD effective theories for describing the interaction at lower energy still need to be experimentally tested.

Box 513, 5600 MB Eindhoven (Netherlands)

    Building Energy Simulation (BES) programmes often use conventional thermal comfort theories to make decisions, whilst recent research in the field of thermal comfort clearly shows that important effects are not incorporated. The conventional theories of thermal comfort were set up based on steady state laboratory experiments. This, however, is not representing the real situation in buildings, especially not when focusing on residential buildings. Therefore, in present analysis, recent reviews and adaptations are considered to extract acceptable temperature ranges and comfort scales. They will be defined in an algorithm, easily implementable in any BES code. The focus is on comfortable temperature levels in the room, more than on the detailed temperature distribution within that room. (author)

  7. Techno-economic assessment of the need for bulk energy storage in low-carbon electricity systems with a focus on compressed air storage (CAES)

    Science.gov (United States)

    Safaei Mohamadabadi, Hossein

    Increasing electrification of the economy while decarbonizing the electricity supply is among the most effective strategies for cutting greenhouse gas (GHG) emissions in order to abate climate change. This thesis offers insights into the role of bulk energy storage (BES) systems to cut GHG emissions from the electricity sector. Wind and solar energies can supply large volumes of low-carbon electricity. Nevertheless, large penetration of these resources poses serious reliability concerns to the grid, mainly because of their intermittency. This thesis evaluates the performance of BES systems - especially compressed air energy storage (CAES) technology - for integration of wind energy from engineering and economic aspects. Analytical thermodynamic analysis of Distributed CAES (D-CAES) and Adiabatic CAES (A-CAES) suggest high roundtrip storage efficiencies ( 80% and 70%) compared to conventional CAES ( 50%). Using hydrogen to fuel CAES plants - instead of natural gas - yields a low overall efficiency ( 35%), despite its negligible GHG emissions. The techno-economic study of D-CAES shows that exporting compression heat to low-temperature loads (e.g. space heating) can enhance both the economic and emissions performance of compressed air storage plants. A case study for Alberta, Canada reveals that the abatement cost of replacing a conventional CAES with D-CAES plant practicing electricity arbitrage can be negative (-$40 per tCO2e, when the heat load is 50 km away from the air storage site). A green-field simulation finds that reducing the capital cost of BES - even drastically below current levels - does not substantially impact the cost of low-carbon electricity. At a 70% reduction in the GHG emissions intensity of the grid, gas turbines remain three times more cost-efficient in managing the wind variability compared to BES (in the best case and with a 15-minute resolution). Wind and solar thus, do not need to wait for availability of cheap BES systems to cost

  5. Basic statistics in cell biology.

    Science.gov (United States)

    Vaux, David L

    2014-01-01

    The physicist Ernest Rutherford said, "If your experiment needs statistics, you ought to have done a better experiment." Although this aphorism remains true for much of today's research in cell biology, a basic understanding of statistics can be useful to cell biologists to help in monitoring the conduct of their experiments, in interpreting the results, in presenting them in publications, and when critically evaluating research by others. However, training in statistics is often focused on the sophisticated needs of clinical researchers, psychologists, and epidemiologists, whose conclusions depend wholly on statistics, rather than the practical needs of cell biologists, whose experiments often provide evidence that is not statistical in nature. This review describes some of the basic statistical principles that may be of use to experimental biologists, but it does not cover the sophisticated statistics needed for papers that contain evidence of no other kind.

    In this study, changes from past to present in the departments of physics, chemistry, biology and mathematics, which are considered as the basic sciences in Turkey, are shown. The importance of basic science for the country emphasized and the status of our country was discussed with a critical perspective. The number of academic staff, the number of students, opened quotas according to years for these four departments at universities were calculated and analysis of the resulting changes were made. In examined graphics changes to these four departments were similar. Especially a significant change was observed in the physics department. Lack of jobs employing young people who have graduated from basic science is also an issue that must be discussed. There are also qualitative results of this study that we have discussed as quantitative. Psychological problems caused by unemployment have become a disease among young people. This study was focused on more quantitative results. We have tried to explain the causes of obtained results and propose solutions.

  15. Research into basic rocks types

    International Nuclear Information System (INIS)

    Teollisuuden Voima Oy (TVO) has carried out research into basic rock types in Finland. The research programme has been implemented in parallel with the preliminary site investigations for radioactive waste disposal in 1991-1993. The program contained two main objectives: firstly, to study the properties of the basic rock types and compare those with the other rock types under the investigation; secondly, to carry out an inventory of rock formations consisting of basic rock types and suitable in question for final disposal. A study of environmental factors important to know regarding the final disposal was made of formations identified. In total 159 formations exceeding the size of 4 km2 were identified in the inventory. Of these formations 97 were intrusive igneous rock types and 62 originally extrusive volcanic rock types. Deposits consisting of ore minerals, industrial minerals or building stones related to these formations were studied. Environmental factors like natural resources, protected areas or potential for restrictions in land use were also studied

    Krogh, F. T.

    1994-01-01

    The Basic Linear Algebra Subprogram (BLAS) library is a collection of FORTRAN callable routines for employing standard techniques in performing the basic operations of numerical linear algebra. The BLAS library was developed to provide a portable and efficient source of basic operations for designers of programs involving linear algebraic computations. The subprograms available in the library cover the operations of dot product, multiplication of a scalar and a vector, vector plus a scalar times a vector, Givens transformation, modified Givens transformation, copy, swap, Euclidean norm, sum of magnitudes, and location of the largest magnitude element. Since these subprograms are to be used in an ANSI FORTRAN context, the cases of single precision, double precision, and complex data are provided for. All of the subprograms have been thoroughly tested and produce consistent results even when transported from machine to machine. BLAS contains Assembler versions and FORTRAN test code for any of the following compilers: Lahey F77L, Microsoft FORTRAN, or IBM Professional FORTRAN. It requires the Microsoft Macro Assembler and a math co-processor. The PC implementation allows individual arrays of over 64K. The BLAS library was developed in 1979. The PC version was made available in 1986 and updated in 1988.

  18. Review of Recent Results from the RHIC Beam Energy Scan

    CERN Document Server

    Kumar, Lokesh

    2013-01-01

    We review recent results from the RHIC beam energy scan (BES) program, aimed to study the Quantum Chromodynamics (QCD) phase diagram. The main goals are to search for the possible phase boundary, softening of equation of state or first order phase transition, and possible critical point. Phase-I of the BES program has recently concluded with data collection for Au+Au collisions at center-of-mass energies ($\\sqrt{s_{NN}}$) of 7.7, 11.5, 19.6, 27, and 39 GeV. Several interesting results are observed for these lower energies where the net-baryon density is high at the mid-rapidity. These results indicate that the matter formed at lower energies (7.7 and 11.5 GeV) is hadron dominated and might not have undergone a phase transition. In addition, the centrality dependence of freeze-out parameters is observed for the first time at lower energies, slope of directed flow for (net)-protons measured versus rapidity shows an interesting behavior at lower energies, and higher moments of net-proton show deviation from Skel...

  19. Bioelectrochemical systems-driven directional ion transport enables low-energy water desalination, pollutant removal, and resource recovery.

    Science.gov (United States)

    Chen, Xi; Liang, Peng; Zhang, Xiaoyuan; Huang, Xia

    2016-09-01

    Bioelectrochemical systems (BESs) are integrated water treatment technologies that generate electricity using organic matter in wastewater. In situ use of bioelectricity can direct the migration of ionic substances in a BES, thereby enabling water desalination, resource recovery, and valuable substance production. Recently, much attention has been placed on the microbial desalination cells in BESs to drive water desalination, and various configurations have optimized electricity generation and desalination performance and also coupled hydrogen production, heavy metal reduction, and other reactions. In addition, directional transport of other types of charged ions can remediate polluted groundwater, recover nutrient, and produce valuable substances. To better promote the practical application, the use of BESs as directional drivers of ionic substances requires further optimization to improve energy use efficiency and treatment efficacy. This article reviews existing researches on BES-driven directional ion transport to treat wastewater and identifies a few key factors involved in efficiency optimization. PMID:26961714
