    The following items are described with the problem of assuring energy required in space as the main subject: (1) Supplying energy for transportation in the space has no other way but to depent on combustion of propulsion chemicals, for which liquefied hydrogen and liquefied oxygen preserved in the space would be most suitable. Energy required for spatial position adjustment of a flying object itself, life maintenance and substance manufacturing in the space would be supplied from electricity. (2) To summarize, satisfying the energy requirement in the space would require availability of electricity, hydrogen and oxygen. Electricity could be supplied from photovoltaic generation, but meeting an aggregate power requirement at a certain moment will require an auxiliary battery, for which again hydrogen and oxygen fuel cells would be used. A conception is proposed for the hydrogen and oxygen supply base in the space, that a plant will be built to manufacture hydrogen and oxygen from water transported from the earth using the solar heat. 2 figs.

    1997-07-01

    This paper studied effects of yen appreciation on the Japanese economy and changes in energy demand when assuming the medium-term yen appreciation trend, and subjects in the energy industry. The paper also refers to the trend of the Asian material industry largely influencing the energy supply/demand, the risk hedge problem of the exchange, and international cooperation and business development of the energy industry. The energy industry is extremely high in public interest and is rice of the industry. Therefore, the development of the business has focused on the domestic market. However, such a recognition is forced to be changed by waves of the worldwide deregulation. Discussions on foreign/domestic price differences caused by high yen and a series of deregulation policy in the energy industry affected thereby may be concrete signs. The subject in the energy industry under the yen appreciation is that the energy industry will be close to common sense in general industrial circles and change to an industry which is strong and internationally competitive enough to brave the exchange variation. 101 refs., 104 figs., 31 tabs.

    Effects extended to industrial areas by new energy development were analyzed by using the industrial relation table. Technological development of new energies can mass-produce energy without being restricted by energy resource availability, and retaining manufacturing facilities can exhibit energy reserve function with security. The technologies may be suitable for local energy supply. In the aspects of industrial policies and people's living, demands on diversification and improvement of the people's living may be responded, levels of scientific technologies may be enhanced, and contribution to improving the industrial structure may be expected. The energy industry includes a large number of related industries and has vast related areas. A large number of technology induced effects can be expected in the course of research and development. A market of huge size may be estimated in the future, by which level elevation of the industrial structure would be supported. Early promotion of the new energy development is an urgent assignment for the 1980's. In order to achieve this goal, it is necessary to promote research and development, proliferation and practical application, for which the physical strength of the present Japan must be utilized to its maximum in making human and fund investments. Expansion and improvement in the industrialization infrastructures are also important, whereas the government's subsidies must be increased, and vitality in the private sector must be incorporated into organized force.

    Pulawski, Szymon

    The phase-transition of strongly interacting matter is a very interesting phenom- ena, which still is not fully understood. Signi cant contribution to improving knowledge about properties of the onset of decon nement of strongly interact- ing matter might come from the NA61/SHINE experiment at CERN. The main goal of this xed-target experiment is to discover the critical point and study the properties of the onset of decon nement. This goal has been reached by the pre- cise measurement of the hadron production in proton-proton, proton-nucleus and nucleus-nucleus interactions in a wide range of system sizes and collision energies. The main goal of this thesis was to obtained two-dimensional spectra of positively and negatively charged pions, kaons and protons produced in p + p interactions at SPS energy range (20 ; 30 : 9 ; 40 ; 80 ; 158 GeV=c ). This studies are necessary for understanding of the onset of decon nement. For this purpose, identi cation and correction techniques dedicated...

  6. Shining the light on smart grid investments : a Duke energy case study

    Utilities and other agencies must fully consider the costs, benefits, and strategies required for smart grid implementation. While pilot programs are useful for evaluating the features of utility smart grid applications, they do not provide an accurate account of peak period load savings for utility service areas over time. In addition, many factors are likely to influence peak hour electricity in the future, and may also influence smart grid savings projections. In this study, the market analysis and information system (MAISY) residential agent-based model was used to simulate a smart grid program at the individual customer level by smoothing individual central air conditioner and heating hourly loads over peak hours. The model was developed to reflect utility and customer-sited control technologies as well as reductions in electricity use based on price responsiveness. The model provided a more reliable simulation approach than aggregate elasticity modelling methods as it was able to estimate hourly load reductions based on real end use data. A case study of the Duke Energy Indiana service area was used to demonstrate the model. 3 figs.

    1997-11-01

    A comparison of the calculated shine through of neutral particle beams in the DIII-D plasma to measured values inferred from the target temperature rise is reported. This provides an opportunity to verify the shine through calculations and makes them more reliable in those cases where the shine through can not be measured. The DIII-D centerpost neutral beam target tiles are safe-guarded against excessive beam shine-through by pyrometry and thermocouple (TC) arrays on the tiles. Shine-through beam power is calculated from the measured temperature changes reported by the target tile TC array. These measurements are performed at the beginning of each operational year at DIII-D. Theoretically, the beam energy deposited into the plasma can be expressed as a function of the change in beam density. Neutral beam energy deposition in plasma (of known density) is inferred by comparing the results of a series of shine-through measurements for the 1997 campaign at DIII-D to the expected shine-through given by theory

    This report represents present status of the study on sky shine and the results made at KEK. At present, data at various facilities can be analyzed by the formula presented by R.H. Thomas. Measurement of sky shine at KEK has been carried out since August, 1977. The neutron level around the accelerator, spatial distribution, energy spectra and the intensities at far distant places were measured. The radiation level at the surface of shield of the accelerator is less than 0.8 mrem/h. Therefore, high sensitive detectors are required to measure the neutron at the far distant places. A 2 inch diameter BF 3 detector with polyethylene moderator and a 5.8 inch diameter BF 3 detector with same moderator were used for the measurement. Conversion from the obtained counting rate to the dose rate was made by using the conversion coefficient for fission neutrons of Cf-252. The dose rate distributions at the shielding surface of the main ring of the accelerator and the counter experiment hall were measured. At the main ring, the dose rate was less than 0.16 mrem/h, and at the counter hall the maximum dose rate was 5 mrem/h. The distance dependence of the sky shine level was measured, and the effective attenuation distance was 1300 m. The result can be expressed by the formula by Thomas. (Kato, T.)

    A tendency toward the rapid yen appreciation since spring 1995 has affected various fields of the economic society of Japan. From a broader view, it is discussed whether the Japanese economic system itself is right or wrong, and that the post-war economic system and regulation system should be largely reviewed. In a short term, the yen appreciation largely affects the export industry and is markedly influential to macro economy. At present, the yen is not as high as that in 1995, but a lot of economists assume a tendency toward medium- and long-term yen appreciation. Therefore, this paper analyzed what kinds of influences the exchange fluctuation brings to the Japanese economy and energy supply/demand. It was clarified what kinds of problems will appear in the energy industry, in particular, on the assumption that the yen will keep high in medium- and long-term. The report consists of parts 1 and 2. Described were `Simulational analysis of yen appreciation` in Part 1 and `Yen appreciation and international issues` in Part 2. 12 figs., 5 tabs.

    NA61/SHINE at the CERN SPS is a fixed-target experiment pursuing a rich physics program including measurements for heavy ion, neutrino and cosmic ray physics. The main goal of the ion program is to explore the most interesting $T, mu_{B}$ region of the phase diagram of strongly interacting matter. We plan to study the properties of the onset of deconfinement and to search for the signatures of the critical point. The search is performed by varying collision energy (13A-158A GeV/c) and system size (p+p, Be+Be, Ar+Ca, Xe+La). Thanks to its large acceptance and excellent particle identification capability NA61/SHINE is well suited for performing high-precision particle production measurements as well as for studying event-by-event fluctuations in p+p, p+nucleus and nucleus+nucleus collisions. Preliminary results on p+p interactions at 20, 31, 40, 80 and 158 GeV/c are presented. They include inclusive spectra of pi+, pi-, K- and protons as a function of transverse momentum/mass and rapidity as well as event-by-ev...

    The main physics goals of the NA61/SHINE programme on strong interactions are the study of the properties of the onset of deconfinement and the search for signatures of the critical point of strongly interacting matter. These goals are pursued by performing an energy (beam momentum 13A -158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This publication reviews results and plans of NA61/SHINE. In particular, recent inclusive spectra and new results on fluctuations and correlations of identified hadrons in inelastic p+p and centrality selected Be+Be interactions at the SPS energies are presented. The energy dependence of quantities inspired by the Statistical Model of the Early Stage (kink, horn and step) show unexpected behavior in p+p collisions. The NA61/SHINE results are compared with the corresponding data of other experiments and model predictions.

    The Super Proton Synchrotron (SPS) at CERN covers one of the most interesting regions of the phase diagram (T - \\mu_{B}) of strongly interacting matter. The study of central Pb+Pb collisions by NA49 indicate that the threshold for deconfinement is reached already at the low SPS energies. Theoretical considerations predict a critical point of strongly interacting matter at energies accessible at the SPS. The NA61/SHINE experiment, a successor of the NA49 project, will study hadron production in p+p, p+A, h+A, and A+A reactions at various energies. The broad physics program includes the investigation of the properties of strongly interacting matter, as well as precision measurements of hadron spectra for the T2K neutrino experiment and for the Pierre Auger Observatory and KASCADE cosmic-ray projects. The main physics goals of the NA61/SHINE ion program are to study the properties of the onset of deconfinement at low SPS energies and to find signatures of the critical point of strongly interacting matter.

This contribution presents results on transverse momentum and multiplicity fluctuations from the Be+Be and p+p energy scan. Also, results on two-particle correlations in pseudorapidity and azimuthal angle obtained in p+p interactions will be shown. The influence of conservation laws and resonance decays on multiplicity and chemical fluctuations of identified particles in p+p interactions will be discussed. Obtained results will be compared with data from other experiments and with model predictions.

    Shining light through walls? At first glance this sounds crazy. However, very feeble gravitational and electroweak effects allow for this exotic possibility. Unfortunately, with present and near future technologies the opportunity to observe light shining through walls via these effects is completely out of question. Nevertheless there are quite a number of experimental collaborations around the globe involved in this quest. Why are they doing it? Are there additional ways of sending photons through opaque matter? Indeed, various extensions of the standard model of particle physics predict the existence of new particles called WISPs - extremely weakly interacting slim particles. Photons can convert into these hypothetical particles, which have no problems to penetrate very dense materials, and these can reconvert into photons after their passage - as if light was effectively traversing walls. We review this exciting field of research, describing the most important WISPs, the present and future experiments, the indirect hints from astrophysics and cosmology pointing to the existence of WISPs, and finally outlining the consequences that the discovery of WISPs would have.

    2012-12-01

    Climate and demographics are primary drivers of regional resource sustainability. In today's global economy, increasing trade has provided a mechanism to alleviate regional stresses. However, increasing regional income promotes consumption, aggravating regional and global resource pressures. South Asia, has the highest population density at a sub-continent scale. Given its monsoonal climate, and high intensity of agriculture it faces perhaps the most severe population weighted water stress in the world. Rapidly declining groundwater tables and the associated high energy use for pumping for irrigated agriculture translate into unsustainable energy imports and expenditure that contributed to the two largest blackouts in global history in summer 2012. Access to water has been progressively declining for both rural and urban populations for the last 3 decades. The increasing energy imports and poor grid reliability translate into limits to the growth of manufacturing and exports of goods and services. The growing income inequity within the population and across national borders, and the impacts of floods and droughts on access to water, food and energy collectively suggest a very high risk for social unrest and a conflict flashpoint. I present a scenario analysis that establishes this case for the emergence of internal and external strife in the region as an outcome of the current resource and natural disaster management policies in the region. Prospects for strategic policy changes for water and energy management and the design of a food procurement and distribution system that could lead to a better future are discussed.

  2. 'Mars-shine'

    2005-01-01

    [figure removed for brevity, see original site] 'Mars-shine' Composite NASA's Mars Exploration Rover Spirit continues to take advantage of favorable solar power conditions to conduct occasional nighttime astronomical observations from the summit region of 'Husband Hill.' Spirit has been observing the martian moons Phobos and Deimos to learn more about their orbits and surface properties. This has included observing eclipses. On Earth, a solar eclipse occurs when the Moon's orbit takes it exactly between the Sun and Earth, casting parts of Earth into shadow. A lunar eclipse occurs when the Earth is exactly between the Sun and the Moon, casting the Moon into shadow and often giving it a ghostly orange-reddish color. This color is created by sunlight reflected through Earth's atmosphere into the shadowed region. The primary difference between terrestrial and martian eclipses is that Mars' moons are too small to completely block the Sun from view during solar eclipses. Recently, Spirit observed a 'lunar' eclipse on Mars. Phobos, the larger of the two martian moons, was photographed while slipping into the shadow of Mars. Jim Bell, the astronomer in charge of the rover's panoramic camera (Pancam), suggested calling it a 'Phobal' eclipse rather than a lunar eclipse as a way of identifying which of the dozens of moons in our solar system was being cast into shadow. With the help of the Jet Propulsion Laboratory's navigation team, the Pancam team planned instructions to Spirit for acquiring the views shown here of Phobos as it entered into a lunar eclipse on the evening of the rover's 639th martian day, or sol (Oct. 20, 2005) on Mars. This image is a time-lapse composite of eight Pancam images of Phobos moving across the martian sky. The entire eclipse lasted more than 26 minutes, but Spirit was able to observe only in the first 15 minutes. During the time closest to the shadow crossing, Spirit's cameras were programmed to take images every 10 seconds. In the first three

    For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in Bangladesh, a basic survey was conducted into Bangladeshi energy policy, trend of supply and demand, steelmaking industry, cement making industry, and chemical fertilizer making industry. Bangladesh in fiscal 1997 consumed 10-million tons of energy in terms of oil, 60% or more in natural gas (domestic), 20% in oil, and the remaining 20% in others. Approximately 15% of all the households were supplied with electric power. There was no integrated production plant in the steelmaking industry. Only one mill performed calcination in the cement making industry. The impact to be imposed by the steelmaking and cement making industries on Bangladeshi energy consumption would be small. Fertilizer making was an important industry outputting 2.6-million tons, responsible for 30% of natural gas consumption. The highest priority was given to facility rehabilitation and production enhancement, and there was little hope that energy conservation facilities/technologies would be introduced into the steelmaking and fertilizer making industries. It was possible, however, that the horizontal tube mill would be replaced by a vertical roller mill in the cement making industry. (NEDO)

    A range modulator wheel (RMW) is an essential component in passively scattered proton therapy. We have observed that a proton beam spot may shine on multiple steps of the RMW. Proton dose calculation algorithms normally do not consider the partial shining effect, and thus overestimate the dose at the proximal shoulder of spread-out Bragg peak (SOBP) compared with the measurement. If the SOBP is adjusted to better fit the plateau region, the entrance dose is likely to be underestimated. In this work, we developed an algorithm that can be used to model this effect and to allow for dose calculations that better fit the measured SOBP. First, a set of apparent modulator weights was calculated without considering partial shining. Next, protons spilled from the accelerator reaching the modulator wheel were simplified as a circular spot of uniform intensity. A weight-splitting process was then performed to generate a set of effective modulator weights with the partial shining effect incorporated. The SOBPs of eight options, which are used to label different combinations of proton-beam energy and scattering devices, were calculated with the generated effective weights.

    Inter-industry relations tables and energy statistics are combined for Asian countries for the preparation of energy analysis oriented inter-industry relations tables, which are used to metrically analyze Aisan nations' industrial structures and energy consumption structures for the ultimate purpose of grasping the magnitude of each industry's demand for energy. The tables prepared this year cover Korea, Indonesia, Thailand, and the Philippines. In Korea, the self-sufficiency rate of mineral fuels is low at 23.1%, which is due to its import of crude oil from abroad. It consumes 177.92-million tons (in terms of oil) of energy for its economic activities, with energy saving measures expected to work effectively here. Indonesia's mineral fuel self-sufficiency rate is high at 84.3% because it is an oil producing country. The energy it consumes for its economic activities is 179.37-million tons (in terms of oil), and energy saving measures will work effectively here. Thailand is a crude oil importing country. Its mineral fuel self-sufficiency rate is 33.4% and the energy its economic activities consume is 53.08-million tons (in terms of oil), and energy saving measures will work effectively in this country. The Philippines is a crude oil importing country and its mineral fuel self-sufficiency rate is as low as 4.8%. It consumes 22.71-million tons of energy (in terms of oil) for its economic activities, and energy-saving measures are expected to take effect here. (NEDO)

  8. Whatever Shines Should be Observed

    2003-08-01

    It is good to mark the new Millennium by looking back as well as forward. Whatever Shines should be Observed looks to the nineteenth century to celebrate the achievements of five distinguished women, four of whom were born in Ireland while the fifth married into an Irish family, who made pioneering contributions to photography, microscopy, astronomy and astrophysics. The women featured came from either aristocratic or professional families. Thus, at first sight, they had many material advantages among their peers. In the ranks of the aristocracy there was often a great passion for learning, and the mansions in which these families lived contained libraries, technical equipment (microscopes and telescopes) and collections from the world of nature. More modest professional households of the time were rich in books, while activities such as observing the stars, collecting plants etc. typically formed an integral part of the children's education. To balance this it was the prevailing philosophy that boys could learn, in addition to basic subjects, mathematics, mechanics, physics, chemistry and classical languages, while girls were channelled into 'polite' subjects like music and needlework. This arrangement allowed boys to progress to University should they so wish, where a range of interesting career choices (including science and engineering) was open to them. Girls, on the other hand, usually received their education at home, often under the tutelage of a governess who would not herself had had any serious contact with scientific or technical subjects. In particular, progress to University was not during most of the nineteenth century an option for women, and access to scientific libraries and institutions was also prohibited. Although those women with aristocratic and professional backgrounds were in a materially privileged position and had an opportunity to 'see' through the activities of their male friends and relatives how professional scientific life was lived

    We analyze geometrical scaling (GS) of negative pion multiplicity p_T distributions at NA61/SHINE energies. We show that even though NA61/SHINE energies are low, one may expect to find GS in the particle spectra. We argue that qualitative behavior of ratios of multiplicities at different energies is in agreement with a simple picture of GS which is violated for p_T smaller than some nonperturbative scale Lambda and when larger Bjorken x of one of the scattering patrons crosses x_max above which gluonic cloud becomes dilute and quark degrees of freedom become important.

Corresponding to construction of an environment-friendly recycling economic society and economic growth as estimated change in social and industrial structure during 2010-2025, major themes are reuse of machine tools, energy saving, environment design, chip treatment and resource recovery. With preparation of information infrastructures in an advanced information society, major issues are 3D-CAD, remote diagnosis, remote control and self-restoration. Because of decline of the birth rate, positive employment of aged persons and women is desirable. New machining technology for new materials, and fusion of various machining technologies are important. For micro-technology, study should be made on the concept and effect of micro-factory (energy saving, space saving, cost reduction, higher accuracy and higher speed). For higher-accuracy machine tool, static, dynamic, thermal and movement characteristics are the key for improving the proper technology. For faster machining. fine basic structural element, faster main spindle and faster feed are important. (NEDO)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

    Full Text Available Charmonium production in heavy ion collisions is considered as an important diagnostic probe for studying the phase diagram of strongly interacting matter for potential phase transitions. The interpretation of existing data from the CERN SPS is hampered by a lack of knowledge on the properties of open charm particle production in the fireball. Moreover, open charm production in heavy ion collisions by itself is poorly understood. To overcome this obstacle, the NA61/SHINE was equipped with a Small Acceptance Vertex Detector (SAVD, which is predicted to make the experiment sensitive to open charm mesons produced in A-A collisions at the SPS top energy. This paper will introduce the concept and the hardware of the SAVD. Moreover, first running experience as obtained in a commissioning run with a 150 AGeV/c Pb+Pb collision system will be reported.

    The paper grasps the present situation of economy and industry in Kazakhstan and studies a policy for developing the industrial machine manufacturing industry of the country. Since the independence in 1992, the country is now at the great turning point in politics, economy, society and industry. The country is forced to convert from the industrial structure of one local area where much of its own discretion had not been given under the economy system of power centralization to the industrial structure which meets the international economic market system as an independent country. Making good use of agricultural and industrial property in the former U.S.S.R., the country needs to export energy resource like oil, natural gas and coal, and abundant ore resource like iron and non-ferrous metal, which were added with values. As the technical base for it, fostering and strengthening of the industrial machine manufacturing industry is important. At present, the situation is that because of the economic sluggishness, the country cannot manufacture domestically even basic mechanical parts and simply-manufactured parts which are required by the domestic energy industry, machine manufacturing industry, and other industries. The technical program to be proposed by Japan is planned to be worked out later based on the basic research made in fiscal 1993. 6 figs., 14 tabs.

    A numerical analysis of the impact patterns on the Vacuum Vessel produced by Shine Through neutrals during the tangential balanced NBI in TJ-II Helical Axis Stellarator has been done. The results show two main concentrations. The first one the circular part of the Hard Core, near the zone of closest approach of the beam. The second one, the most important, around the beam exit, on the border between the plate of the HC cover and the sector wall. As expected, the Shine Through loads decrease strongly with plasma density, predominating at low density at NBI start, decreasing quickly when density increases and increasing slightly with the beam energy. No overlapping with lost fast ions impacts is observed, that, in addition, show an opposite behaviour with density. (Author) 3 refs

The experiment provides a scan of measurements of particle spectra and fluctuations in proton–proton, proton–nucleus, and nucleus–nucleus interactions as functions of collision energy and system size, corresponding to a two-dimensional phase diagram (T- μ B . New NA61/SHINE results are shown here, including transverse momentum and multiplicity fluctuations in Ar+Sc collisions as compared to NA61 p+p and Be+Be data, as well earlier NA49 A+A results. Recently, a preliminary effect of change in the system size dependence, labelled as the “percolation threshold” or the “onset of fireball”, was observed in NA61/SHINE data. This effect is closely related to the vicinity of the hadronic phase space transition region and will be discussed in the text.

    A report is made outlining the economic situation and industrial policies in Russia and the actual state of energy consuming industries (thermoelectric power generation, oil refining, and iron making) in that country. In Russia, energy efficiency is much lower than in advanced countries in the West, and the improvement of energy efficiency is a serious task to solve in the Russian fuel energy department. Cited to explain the poor efficiency are facilities growing antiquated, delay in the introduction of new technologies and instruments, insufficient maintenance, and the weak consciousness of energy saving. Although the electric power circle and energy related departments are conscious of the need of endeavors for improving energy efficiency, yet it is too difficult for corporations themselves to invest heavily in facilities. When Japan implements a model project for saving energy in Russia, it will be greatly contributing to the improvement of energy supply/demand in Russia, to the stabilization of social and economic states in that country, and to the prevention of global warming.

    The SHINE workshop is an annual meeting of solar and heliospheric scientists which, in addition to aiming to improve understanding of solar disturbances and their propagation to, and effect, on the Earth (shinecon.org), is dedicated to actively supporting students. This dedication is substantiated in part through the National Science Foundation (NSF) providing funding for student attendance to the workshop, which enables student participation. Another example of SHINE's commitment to its student members is the incorporation of a Student Day prior to the workshop since 2003, entirely organized and run by two student representatives. While there are variations in format from year to year, Student Day consists of tutorials and research talks exclusively by student volunteers to an audience of only students. The day is intended to provide a low-stress environment for students to learn about the various topics addressed during the workshop, to ask questions freely, and to engage in scientific discussion with other students which hopefully is a catalyst for collaboration. As a result of positive experiences, over the past decade student attendance and participation in the workshop have increased. At the SHINE 2014 workshop, nearly a third of attendees were students. SHINE student visibility has increased over the years, with student posters being advertised at breakfast, inclusion of a student day summary by the student representatives during a plenary session, and continued support from the steering committee. Students are also promoting a broader impact of SHINE sciences via increased social media presence. From a student representative's perspective, SHINE has built and fostered a healthy student community and encourages students to engage in shaping the future of the field.

    Peroxide formation due to water radiolysis in a uranyl sulfate solution is a concern for the SHINE Medical Technologies process in which Mo-99 is generated from the fission of dissolved low enriched uranium. To investigate the effects of power density and fission on peroxide formation and uranyl-peroxide precipitation, uranyl sulfate solutions were irradiated using a 50-MeV electron linac as part of the micro-SHINE experimental setup. Results are given for uranyl sulfate solutions with both high and low enriched uranium irradiated at different linac powers.

    A numerical analysis of the impact patterns on the Vacuum Vessel produced by Shine Through neutrals during the tangential balanced NBI in TJ-II Helical Axis Stellarator has been done. The results show two main concentrations. The first one the circular part of the Hard Core, near the zone of closest approach of the beam. The second one, the most important, around the beam exit, on the border between the plate of the HC cover and the sector wall. As expected, the Shine Through loads decrease strongly with plasma density, predominating at low density at NBI start, decreasing quickly when density increases and increasing slightly with the beam energy. No overlapping with lost fast ions impacts is observed, that, in addition, show an opposite behaviour with density. (Author) 3 refs.

    This paper outlines a historical change in the shipbuilding industry and describes the features of the shipbuilding industry and the problem and prospect for internationalization. The financial panic in the early years of Showa and World War II caused a destructive damage to the shipbuilding industry in Japan. However, the shipbuilding industry has held the first rank in the world for an annual shipbuilding rate since 1956. A change in the world demand is exceedingly unstable. With 1975 in the peak, the facilities have been reduced to about one-half, and the personnel to about one-fourth. The shipbuilding industry that has already attained to maturity must be more rationalized. Moreover, it requires the demand cultivation and new product creation in the wide field of a very high speed cargo boat, luxury passenger boat, automated boat, and energy-saving boat. The competitive power in price must be improved by modernization, informationalization, and systematization (i.e., various facilities and robots at the factory). Especially, short- and long-term policies and prospects must be proposed in consideration of rationalization and high precision of the welding that occupies the greater part of the shipbuilding industry. 6 refs., 3 figs., 3 tabs.

  19. NA61/SHINE Data For Long Baseline Neutrino Experiments

    Hälser, Alexis

    2015-01-01

    Accelerator based long baseline neutrino experiments require precise neutrino fl ux predictions to reach their physics goals. These experiments are commonly based on a set of two detectors. At the near detector, cross section measurements are performed and the neutrino fl ux can be observed before oscillation, while at the far detector the signal for neutrino oscillations is studied. An accurate knowledge on hadron production is mandatory in order to predict the neutrino fluxes. The NA61/SHINE facility at the CERN SPS has proven its ability to deliver high quality measurements of hadron production for the long baseline neutrino experiments. In this paper, the latest results from N A61 /SHINE for the neutrino physics programme are reviewed and future plans are presented.

    Based on assurance of energy availability in Sado Island, and age advancing of the population, an energy vision was established with the target of building 'Mano Town that seem real to everyone to find it good to live therein'. The population of Mano Town is about 6000 persons, and the energy consumption in total is 22,350 kl/year as converted into petroleum (industries and public sector at 12,162, households at 2,720, and transportation at 7,433). The new energy introduction is divided into three steps of the initial stage, middle stage, and long term stage. The initial stage will execute introduction of photovoltaic power generation into primary schools, promotion of utilization of solar energy at homes, promotion of introducing firewood and chaff boilers, and introduction of cogeneration into Yutoripia Mano. For the middle stage, discussions were given on introduction of photovoltaic power generation into the city office building, manufacture of light oil substituting fuel through rape seed and soy bean cultivation, introduction of hybrid automobiles, and manufacture of pellet fuel by utilizing wood wastes. For the long term stage, discussions were given on wind power generation, and ethanol fuel manufacture. (NEDO)

    Dark matter pair production at high energy colliders may leave observable signatures in the energy and momentum spectra of the objects recoiling against the dark matter. We use LEP data on monophoton events with large missing energy to constrain the coupling of dark matter to electrons. Within a large class of models, our limits are complementary to and competitive with limits on dark matter annihilation and on WIMP-nucleon scattering from indirect and direct searches. Our limits, however, do not suffer from systematic and astrophysical uncertainties associated with direct and indirect limits. For example, we are able to rule out light (< or approx. 10 GeV) thermal relic dark matter with universal couplings exclusively to charged leptons. In addition, for dark matter mass below about 80 GeV, LEP limits are stronger than Fermi constraints on annihilation into charged leptons in dwarf spheroidal galaxies. Within its kinematic reach, LEP also provides the strongest constraints on the spin-dependent direct detection cross section in models with universal couplings to both quarks and leptons. In such models the strongest limit is also set on spin-independent scattering for dark matter masses below ∼4 GeV. Throughout our discussion, we consider both low energy effective theories of dark matter, as well as several motivated renormalizable scenarios involving light mediators.

    Yoshida et al. reported transmission electron microscopy imaging of CO molecules adsorbed on Au nanoparticles5. However, when gas is present in the microscope column the electron wave is modified due to gas-electron interactions6, 7. Several factors have to be taken into account when combining high......-energy electrons with a gaseous environment. The fast electrons are scattered both elastically and inelastically by the gas molecules resulting in distortions of the electron wave both above and below the sample, thus altering the incoming and the exit wave carrying the image information. Furthermore......, the interaction between fast electrons and gas molecules leads to ionization of the gas molecules. A full understanding of both the interaction of fast electrons with gas molecules and the effect of gas on high‐resolution imaging is therefore necessary to take the next step towards quantitative ETEM.

    The NA61/SHINE experiment studies hadron production in hadron+hadron, hadron+nucleus and nucleus+nucleus collisions. The strong interactions program has two main purposes: study the properties of the onset of deconfinement and search for the signatures of the critical point of strongly interacting matter. This aim is pursued by performing a two-dimensional scan of the phase diagram by varying the energy/momentum (13A-158A GeV/c) and the system size (p+p, Be+Be, Ar+Sc, Xe+La) of the collisions. This publication reviews recent results from p+p, Be+Be and Ar+Sc interactions. Measured particle spectra are discussed and compared to NA49 results from Pb+Pb collisions. The results illustrate the progress towards scanning the phase diagram of strongly interacting matter.

    A method and a device for preventing rust in annealed coils using volatile corrosion inhibitor (VCI) were put into practical use. Air cooling using dehumidified air and corrosion inhibiting air cooling have been used to prevent rusting caused by condensation on surfaces of coils being cooled, but these methods consume a very large amount of energy. As a result of discussing new corrosion inhibiting methods, cyclohexylamine carbonate (CHC) showed a highest corrosion prohibition capability as a VCI. Because CHC has a strong odor, new deodorants have been searched by combining it with special metallic salts. It was found that the range where a deodorant can be added without impeding the corrosion prohibiting effect is from 20% to 30%. A test for practical application indicated that rusting could be suppressed even using a VCI with concentration as low as 0.4 ppm to 0.8 ppm if the velocity of cooling air on coil surfaces is held from 0.2 m/s to 0.4 m/s. A high-accuracy continuous CHC analyzing method was established that uses a nitrogen oxide analyzer. The required installation space was reduced to 1/15 to 1/20 and the running cost to 1/8 to 1/10 of conventional methods. 11 figs., 4 tabs.

    Collider experiments are one of the most promising ways to constrain Dark Matter (DM) interactions. For several types of DM-Standard Model couplings, a meaningful interpretation of the results requires to go beyond effective field theory, considering simplified models with light mediators. This is especially important in the case of loop-mediated interactions. In this paper we perform the first simplified model study of the magnetic dipole interacting DM, by including the one-loop momentum-dependent form factors that mediate the coupling — given by the Dark Penguin — in collider processes. We compute bounds from the monojet, monophoton, and diphoton searches at the 8 and 14 TeV LHC, and compare the results to those of direct and indirect detection experiments. Future searches at the 100 TeV hadron collider and at the ILC are also addressed. We find that the optimal search strategy requires loose cuts on the missing transverse energy, to capture the enhancement of the form factors near the threshold for on-shell production of the mediators. We consider both minimal models and models where an additional state beyond the DM is accessible. In the latter case, under the assumption of anarchic flavor structure in the dark sector, the LHC monophoton and diphoton searches will be able to set much stronger bounds than in the minimal scenario. A determination of the mass of the heavier dark fermion might be feasible using the M{sub T2} variable. In addition, if the Dark Penguin flavor structure is almost aligned with that of the DM mass, a displaced signal from the decay of the heavier dark fermion into the DM and photon can be observed. This allows us to set constraints on the mixings and couplings of the model from an existing search for non-pointing photons.

    This software is a new target for the Spacecraft Health Inference Engine (SHINE) knowledge base that compiles a knowledge base to a language called Tiny C - an interpreted version of C that can be embedded on flight processors. This new target allows portions of a running SHINE knowledge base to be updated on a "live" system without needing to halt and restart the containing SHINE application. This enhancement will directly provide this capability without the risk of software validation problems and can also enable complete integration of BEAM and SHINE into a single application. This innovation enables SHINE deployment in domains where autonomy is used during flight-critical applications that require updates. This capability eliminates the need for halting the application and performing potentially serious total system uploads before resuming the application with the loss of system integrity. This software enables additional applications at JPL (microsensors, embedded mission hardware) and increases the marketability of these applications outside of JPL.

Through the observation of super spiral DNA fixed on a spermin or spermidine treated mica substrate by AFM (atomic force microscope), fixation of DNA without any deformation in solution was clarified, and visualization of the spiral structure of DNA were successfully achieved. Manipulation of Xe atoms adsorbed on an Si(111) surface was certainly possible by using STM (scanning tunneling microscope)/atom probe equipment. A nucleation mechanism in crystal growth was studied for various organic source-molecules/GaAs(001) surface systems, and formation of high-density nuclei on the GaAs surface was achieved by accelerating the translational energy of Ga material molecules up to 6eV or more. Ziegler- Natta catalysis important for industrial polymerization of olefin molecules was precisely analyzed by first-principle dynamic simulation.

    In FY14, we studied the qualitative and quantitative behavior of a SHINE/PNL tritium nozzle under varying operating conditions. The result is an understanding of the nozzle’s performance in terms of important flow features that manifest themselves under different parametric profiles. In FY15, we will consider nozzle design with a focus on nozzle geometry and integration. From FY14 work, we will understand how the SHINE/PNL nozzle behaves under different operating scenarios. The first task for FY15 is to evaluate the FY14 model as a predictor of the actual flow. Considering different geometries is more time-intensive than parameter studies, therefore we recommend considering any relevant flow features that were not included in the FY14 model. In the absence of experimental data, it is particularly important to consider any sources of heat in the domain or boundary conditions that may affect the flow and incorporate these into the simulation if they are significant. Additionally, any geometric features of the beamline segment should be added to the model such as the orifice plate. The FY14 model works with hydrogen. An improvement that can be made for FY15 is to develop CFD properties for tritium and incorporate those properties into the new models.

    Argonne National Laboratory is assisting SHINE Medical Technologies in their efforts to develop the technology to become a domestic Mo-99 producer using low-enriched uranium (LEU). Mini-SHINE experiments are being performed with the high-current electron linear accelerator (linac) at Argonne. The target solution is a 90-150 g-U/L LEU uranyl sulfate at pH 1. In Phase 1, the convertor was tantalum with a maximum beam power on the convertor of 10 kW, and the target solution was limited to 5 L. This configuration generated a peak fission power density of 0.05 W/mL. Nine experiments were performed between February and October 2015. Results are reported and discussed for each experiment regarding the off-gas analysis system, the sampling and Mo-recovery operation, and the Mo-product concentration and purification system. In Phase 2, the convertor will be depleted uranium; beam power will increase to 20 kW; and the solution volume will be 18 L. This configuration will generate a fission power density of up to 1 W/mL.

    Although most of the sky-shine radiation levels in industrial radiography are below regulatory limits, sky-shine radiation could make a valuable contribution to the total radiation level near shielding facility with little shielding and open field without shielding. Therefore sky-shine radiation should be thoroughly predicted and supervised with the ALARA principle. In this study, we simulated sky-shine radiation for mobile irradiators using MCNP and newly suggested the equation for calculating sky-shine radiation. Also these results were applied to developing Korean regulatory guidance about industrial radiography and to recommending the requirement of the facility design, controlled or supervised area at work places.

    Argonne is assisting SHINE Medical Technologies (SHINE) in their efforts to develop SHINE, an accelerator-driven process that will utilize a uranyl-sulfate solution for the production of fission product Mo-99. An integral part of the process is the development of a column for the separation and recovery of Mo-99, followed by a concentration column to reduce the product volume from 15-25 L to <1 L. Argonne has collected data from batch studies and breakthrough column experiments to utilize the VERSE (Versatile Reaction Separation) simulation program (Purdue University) to design plant-scale product recovery and concentration processes.

  3. T2K Replica Target Hadron Production Measurements in NA61/SHINE and T2K Neutrino Flux Predictions

    CERN Document Server

    AUTHOR|(SzGeCERN)710687

    Accelerator based neutrino experiments generate their neutrino beams by impinging high energy protons on thick targets. The neutrino beam predictions are thus based on modeling the interactions of the beam protons inside the targets. Different hadronic models can be used with different accuracies depending on the energy range of the incident protons and on the target material. Nevertheless, none of the models can be seen as perfectly describing all different interactions. In order to reach high precision neutrino flux predictions, it is thus mandatory to be able to test and constrain the models with hadron production measurements. The T2K experiment in Japan uses the ancillary NA61/SHINE facility at CERN to constrain the production of hadrons resulting from the interactions of proton beam particles impinging on a 90cm long graphite target. Data taken by NA61/SHINE with a 30 GeV proton beam on a thin (4% interaction length) graphite target have been recorded in 2007 and 2009. They have been analysed and extens...

    The trend of technology development, problems harbored therein, trend of the market, and the like were investigated for supporting the development of technologies for the mass production and commercialization of solar-grade silicon materials. Concerning the future of production enhancement and cost reduction in the manufacture of polycrystalline silicon solar cells, studies were made from the technological viewpoint. The results are shown below. It is estimated that approximately 4,500 tons of material silicon will be necessary in 2005 and 6,500-10,700 tons in 2010. Since the melting purification method of NEDO (New Energy and Industrial Technology Development Organization) now under development step by step toward commercialization as well as the conventional source will provide the necessary amount of material silicon, it is inferred that the development of solar cells will go on without any restraint originating in the semiconductor industry. With the commercialization of the technologies so far developed and the development/commercialization of the fast-acting high-performance solar cell technology, probabilities are high that the polycrystalline silicon solar cell manufacturing cost in 2010 will be as low as to be on the 100 yen/W (93-118 yen/W) level which is the level now held up as the goal.

    Research and development was conducted for enhancing productivity and energy conservation by rendering continuous and automatic the electromagnetic casting process for manufacturing polycrystalline silicon substrates for solar cells. In the manufacture of ingots for substrates by continuous electromagnetic casting, the chuck type system for feeding power to the melt plasma was replaced by a roller type system, and the power feeding position was moved to the high temperature region. Also, an on-line ingot slicing technique was established. In the manufacture of substrates at a slicing rate of 300 {mu}m/minute, productivity of 115,000 wafers/month, yield of 98%, and thickness tolerance of 30 {mu}m were achieved. A high-speed cleaning technique was developed using a jet stream, by which the cleaning time was reduced to 5 minutes and the slurry recovery rate was elevated to 95%. Based on these, substrate-related costs in the case of 100 MW/year production was calculated, which resulted in a cost of 98.8 yen/wafer (target: 103.3 yen/wafer) for manufacturing 15 cm square substrates from ingots and in a 15 cm square substrate slicing and cleaning cost of 135.1 yen/wafer (target: 135.4 yen/wafer).

    Acne therapies that are able to show efficacious treatment of acne lesions as well as to address the issues of oiliness and shine control may be particularly appropriate for the treatment of patients with acne vulgaris that is accompanied by oily skin and facial shine. The microsphere delivery system (MDS), a novel delivery technology for topical therapy, can be customized to optimize product attributes, including oil absorption. Clinical trials have clearly established the efficacy and tolerability of such MDS formulations in the treatment of acne. In addition, studies have shown that the use of products formulated with an MDS provides a more significant reduction in facial shine than non-MDS acne therapy, as well as a reduction in facial sebum accumulation relative to control. Future clinical research should aim to further delineate the effect of individual topical acne treatment formulations on oiliness and shine.

    NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. NA61/SHINE has greatly profited from the long development of the CERN proton and ion sources and the accelerator chain as well as the H2 beamline of the CERN North Area. The latter has recently been modified to also serve as a fragment separator as needed to produce the Be beams for NA61/SHINE. Numerous components of the NA61/SHINE set-up were inherited from its predecessors, in particular, the last one, the NA49 experiment. Important new detectors and upgrades of the legacy equipment were introduced by the NA61/SHINE Collaboration. This paper describes the state of the NA61/SHINE facility - the beams and the detector system - before the CERN Long Shutdown I, which started in March ...

    A feasibility study was conducted for the implementation of the optimum model project in the fiber dyeing and processing industry in Thailand. This paper describes the results of fiscal 1999. Seventy percent of about 400 companies are those heavily consuming energy, while small-scale businesses having a production capacity of less than one million yards/month take the sixty percent of the industry. Their energy conserving measures are behind. Measures against ground subsidence and drainage cost these companies greatly. Trade competition with China and others is being intensified. Although designated under the Energy Saving Promotion Act, the plants are not enjoying the privilege. Needed for the energy saving measures are grasp of the current situation such as energy consumption status, thorough operation management, improvement of energy efficiency in the present production facilities, renewal/additional installation of production equipment, and implementation of developmental energy saving measures. As energy conservation measures are deemed adaptable to the industry if the investment recovery period is two years or less, diagnostic analysis was made on six plants, with diffusion of the result examined. The total energy consumption of the industry was estimated to be reducible by 35% through high-recovery-rate measures such as improvement of boilers, recovery of exhaust heat, control of energy consumption rate, and introduction of dyeing machines having low liquor ratio.

    2015-07-21

    The interpretation of extensive air shower measurements, produced by ultra-high energy cosmic rays, relies on the correct modeling of the hadron-air interactions that occur during the shower development. The majority of hadronic particles are produced at equivalent beam energies below the TeV range. NA61/SHINE is a fixed target experiment using secondary beams produced at CERN at the SPS. Hadron-hadron interactions have been recorded at beam momenta between 13 and 350 GeV/c with a wide-acceptance spectrometer. In this contribution we present measurements of the spectra of charged pions and the $\\rho^0$ production in pion-carbon interactions, which are essential for modeling of air showers.

    The feasibility study of direct open charm measurements by its decay into two daughter particles, pion and kaon, in central Pb-Pb collision at SPS energies of 158 AGeV and 40 AGeV, shows that such measurements are viable at NA61/SHINE experiment if it is supplemented with a dedicated Vertex Detector (VD). We use AMPT (A Multi-Phase Transport model) event generator to generate the physical input for simulation and employed GEANT4 application to describe particle transport through the experimental setup. The VD will allow for precise track reconstruction at the target proximity. The direct open charm measurements will be a challenging due to the low production yield and short life time of D 0 mesons. The obtained results are based on the predicted yields of D 0 meson by Hadron String Dynamic (HSD) model. This study also addresses the issue of VD optimization and the emphasis is put on the prospect of the development of a VD based on CMOS technology

    The field research of oil conservation was conducted in developing countries, in particular, Vietnam where a steep increase in oil consumption is anticipated in the future. Energy conservation is the most effective direct measures to control combustion of fossil fuels, and an important issue to be promoted by all countries in the world to prevent global warming and reserve energy resources. In fiscal 1994, main industries in the northern part of Vietnam were researched. In fiscal 1995, the report meeting of plant survey results in the northern part and the technical seminar of energy-saving in industrial field were held, and plants around Ho Chi Minh City in the southern part of Vietnam were researched. Although Vietnam has recently acquired membership in ASEAN and is undergoing dramatic economic growth, has many problems in environmental measures. Japan has top-ranking results on energy-saving in industrial field, and the transfer of such superior technologies and techniques will greatly contribute to resource and global warming problems as well as pollution control measures in Vietnam. 13 refs., 25 figs., 26 tabs.

Field surveys have been conducted to find out the needs of energy saving and environmental technology for the efficient consumption of petroleum in the developing countries with mass-consumption of petroleum in the future. The survey was conducted in the Philippines in the FY 1996. Next developing themes were proposed. The first theme was developing method of sugar plant. The magnesia method has been developed as a basic technology for cleaning sugar solution process instead of using lime. By the recycling method, the waste cake amount can be remarkably reduced. The second theme was electron beam exhaust gas treatment by a dry method of simultaneous desulfurization and denitrification of high concentration SOx and NOx in the fertilizer production plants. The third theme was the energy saving technology for SOx reduction of heating furnace for iron-steel by using an ultra energy saving-type regenerative burner. The last theme was chlorine bypass technology in cement industry, which would become an advanced technology development for the use of chlorine containing fuels in the near future. 40 refs., 36 figs., 79 tabs.

    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.

In relation to selection, separation, and purification functions in field (1), studies are made about electrochemical cell structure control and cell constituting materials for enabling a high efficiency NOx purification reaction. As for the energy conversion function, studies are made about the improvement of characteristics of oxide based thermoelectric conversion materials and about changes in electrical output due to their development into cells. In a study of novel thermoelectric conversion materials, K{sub 2}NiF{sub 4} type Y{sub 0.33}Sr{sub 1.67}(Ni{sub 1-y}Co{sub y})O{sub 4-{sigma}} and Ce{sub 0.25}Sr{sub 1.75}(Ni{sub 1-y}M{sub y})O{sub 4-{sigma}} (M=Fe, Co) are synthesized, and electrical resistivity levels and Seebeck coefficients are determined at room temperature-800 degrees C in an oxygen current. Seebeck coefficients are found to be negative for all specimens, which shows that they are n-type conductors. Ce{sub 0.25}Sr{sub 1.75}(Ni{sub 0.7}Fe{sub 0.8})O{sub 4-{sigma}} exhibits the greatest output factor of 0.064 times 10{sup -4}Wm{sup -1}K{sup -2} (400 degrees C). (NEDO)

    High efficiency power generation, which is useful for promoting the environment-friendly type energy and coordinated community, is investigated by combining a steam turbine power generation system using the PS-RDF (paper sludge-refuse derived fuel) and a gas turbine (GT) combined cycle. Industrialization plan for processing PS in low cost has been made to ensure the profitability by participating the wholesale power supply under the law of electric power industry. This combined system is similar to the so-called super power generation using municipal garbage, but the lower temperature of steam from GT waste heat boilers (WHB) is super-heated by the flue gas from RDF boiler, which is called advanced power generation system (A.S.S.). The total power generation capacity is 149,000 kW, which consists of three 35,000 kW units of GT and one 44,000 kW unit of steam turbine. When comparing the combined system (A.S.S.) and usual one with the independent installation of the RDF steam power generation system and a GT combined cycle, the A.S.S. provides the repowering efficiency of 7,600 kW output with exactly the same quantity of fuel input as usual one. 71 figs., 31 tabs.

    The paper described the results of the survey of the formed raw material field in relation to the FY 1999 long-term energy technology strategy. In the advancing international specialization, efforts are being made for the secure basic base technology force and cost reduction required for competition, and at the same time the aim is not to retain/improve all the formed raw material technologies, but to discriminate the materials in the aspects except the cost. By promoting the reformation into the proposed type industry, it is necessary to work out the bold strategy including the review of the system/structure for promoting the strategic technology innovation by aiming at the important formed raw material technology which can be a life line for the assembly industry, in particular. Concretely, the comprehensive technology system which concentrated a variety of engineering knowledge/information was constructed. The system is shifted to the one that adopted information/communication technology. The conversion in the early time to the proposed type industry is attempted. Japan acquires capability for heightening the level of technology, by which Japan will continue leading the formed raw material technology to the world's top level. Japan realizes the network consisting of the industry, university and government. The environment is realized where new personnel will naturally enter the formed raw material industry and bottom up the total technology force. (NEDO)

    An optimal amount of argon gas carrying CaSi additive particles was discovered in a continuous casting process and a stable operation method was established to conserve energy and cost. CaSi particles are added into molten steel to prevent steel materials from cracking, and argon gas is used in carrying the CaSi particles to prevent oxygen and nitrogen from mixing into the molten steel. The proposed modification plan intends to use the existing facilities up to the seal rotary machine, and to reduce the size and length of the carrying pipes thereafter, the length of the flexible tubes, and the size of the booster. A verification test was carried out. As a result of measuring the CaSi particle scattering distribution, it was found that an in-pipe flow velocity of 25 m/s produces a narrow scattering distribution and has the particles impinge on the molten steel dropping position concentratedly. It was also learned that the in-pipe flow velocity of 25 m/s can increase the solid-air ratio to 0.81 to 1.21. Operations of the modified machine reduced the argon gas amount by 5.2 m[sup 3]N/min (reduction rate of 61%) and realized stabler CaSi particle injection which improved the Ca yield by 9.4%. 14 figs., 7 tabs.

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a steel technology field. Japanese steel industry should correspond to requirements of the international economic society as the top runner. Although it is now difficult to suppose a basic technology innovation, stable supply of basic materials is necessary for peripheral industries. The basic raw material technology is the basis of domestic and overseas socio- economic activities. The technology development support system to retain the world-wide leadership of Japanese industries is a strategic issue. Preparation of cooperative R and D bases of industry, academia and government along a national policy is important. Strong promotion of such national projects is also essential as global environment problem, positive use of advanced information tools, development of technologies and products of unexplored fields, and development of new products and demand creation according to social needs. Such measures along social requirements are also important as raw material development to double an energy efficiency, and the policy and system to construct a recycling society and living spaces.

    For rational use of energy resources, the process technology which allows harmonization and multiplication of conflicting characteristics was developed for development of new ceramic system materials. This paper summarizes the result in fiscal 1997. On a structural reaction process among creation technologies of ultra-reliable structure, study was made on structure control and hot-working technology through atmosphere control in ceramics synthesis. On basic technology for analysis and evaluation, study was made on the effect of particle bridging on strengthening and toughening of ceramic materials. Study was also made on a toughness expression mechanism, FEM model analysis of particle bridging, and crack growth resistance of ceramics. On control of solid solution precipitation, new alumina ceramics with high strength, hardness and wear resistance was obtained by transgranularly precipitating nano-size particles from a fine-grain high-density matrix through an improved particle formation process. Its toughness was considerably improved by controlling grain shape and grain boundary structure. A precipitation mechanism was also discussed. 89 refs., 107 figs., 14 tabs.

    Poisson noise is one of the factors degrading scintigraphic images, especially at low count level, due to the statistical nature of photon detection. We have developed an original procedure, named statistical and heuristic image noise extraction (SHINE), to reduce the Poisson noise contained in the scintigraphic images, preserving the resolution, the contrast and the texture. The SHINE procedure consists in dividing the image into 4 x 4 blocks and performing a correspondence analysis on these blocks. Each block is then reconstructed using its own significant factors which are selected using an original statistical variance test. The SHINE procedure has been validated using a line numerical phantom and a hot spots and cold spots real phantom. The reference images are the noise-free simulated images for the numerical phantom and an extremely high counts image for the real phantom. The SHINE procedure has then been applied to the Jaszczak phantom and clinical data including planar bone scintigraphy, planar Sestamibi scintigraphy and Tl-201 myocardial SPECT. The SHINE procedure reduces the mean normalized error between the noisy images and the corresponding reference images. This reduction is constant and does not change with the count level. The SNR in a SHINE processed image is close to that of the corresponding raw image with twice the number of counts. The visual results with the Jaszczak phantom SPECT have shown that SHINE preserves the contrast and the resolution of the slices well. Clinical examples have shown no visual difference between the SHINE images and the corresponding raw images obtained with twice the acquisition duration. SHINE is an entirely automatic procedure which enables halving the acquisition time or the injected dose in scintigraphic acquisitions. It can be applied to all scintigraphic images, including PET data, and to all low-count photon images

    The interpretation of extensive air shower measurements, produced by ultra-high energy cosmic rays, relies on the correct modelling of the hadron-air interactions that occur during the shower development. The majority of hadronic particles is produced at equivalent beam energies below the TeV range. NA61/SHINE is a fixed target experiment at the CERN Super Proton Synchrotron, studying hadron production in hadron-nucleus and nucleus-nucleus collisions to provide valuable contributions to a number of subjects, from neutrino through cosmic-ray to heavy-ion physics. Pion-Carbon interactions have been performed, at 158 and 350 GeV/c, to give precise particle production measurements for the most numerous projectile in air showers, the π meson. The ability to measure the production of resonances, such as the ρ{sup 0} and ω mesons, is particularly important to predict the number of muons produced in air showers. In this contribution we present updated results of resonance spectra at 158 and 350 GeV/c measured by NA61/SHINE.

    The physics program of the NA61/SHINE (SHINE = SPS Heavy Ion and Neutrino Experiment) experiment at the CERN SPS consists of three subjects. In the first stage of data taking (2007-2008) the measurements of hadron production in hadron-nucleus interactions needed for neutrino (T2K) and cosmic-ray (Pierre Auger and KASCADE) experiments will be performed. In the second stage (2008-2010) hadron production in proton-proton and proton-nucleus interactions needed as a reference data for better understanding of nucleus-nucleus reactions will be studied. In the third stage (2010-2012) hadron production will be measured in nucleus-nucleus collisions, with the aim to identify the properties of the onset of deconfinement and find evidence for the critical point of strongly interacting matter. The experiment was approved at CERN in June 2007. The first pilot run was performed during October 2007. We report here first results from this run.

    Argonne is assisting SHINE Medical Technologies in their efforts to become a domestic Mo-99 producer. The SHINE accelerator-driven process uses a uranyl-sulfate target solution for the production of fission-product Mo-99. Argonne has developed a molybdenum recovery and purification process for this target solution. The process includes an initial Mo recovery column followed by a concentration column to reduce the product volume from 15-25 L to < 1 L prior to entry into the LEU Modified Cintichem (LMC) process for purification.1 This report discusses direct down-scale experiments of the plant-scale concentration column design, where the effects of loading velocity and temperature were investigated.

    Child stunting and anemia are intractable public health problems in developing countries and have profound short- and long-term consequences. The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial is motivated by the premise that environmental enteric dysfunction (EED) is a major underlying cause of both stunting and anemia, that chronic inflammation is the central characteristic of EED mediating these adverse effects, and that EED is primarily caused by high fecal ingestion due to living in conditions of poor water, sanitation, and hygiene (WASH). SHINE is a proof-of-concept, 2 × 2 factorial, cluster-randomized, community-based trial in 2 rural districts of Zimbabwe that will test the independent and combined effects of protecting babies from fecal ingestion (factor 1, operationalized through a WASH intervention) and optimizing nutritional adequacy of infant diet (factor 2, operationalized through an infant and young child feeding [IYCF] intervention) on length and hemoglobin at 18 months of age. Within SHINE we will measure 2 causal pathways. The program impact pathway comprises the series of processes and behaviors linking implementation of the interventions with the 2 child health primary outcomes; it will be modeled using measures of fidelity of intervention delivery and household uptake of promoted behaviors and practices. We will also measure a range of household and individual characteristics, social interactions, and maternal capabilities for childcare, which we hypothesize will explain heterogeneity along these pathways. The biomedical pathway comprises the infant biologic responses to the WASH and IYCF interventions that ultimately result in attained stature and hemoglobin concentration at 18 months of age; it will be elucidated by measuring biomarkers of intestinal structure and function (inflammation, regeneration, absorption, and permeability); microbial translocation; systemic inflammation; and hormonal determinants of growth and anemia

    Indonesia is the biggest iron steel producing country in the ASEAN countries. Most of the production is produced by the electric furnace method in which iron steel scrap is used as a material. However, an energy saving measure in this method, the electric furnace scrap preheater using flue gas, has not yet been spread on a full scale. This R and D is aimed at developing jointly with Indonesia an electric furnace scrap preheater for medium/small size electric furnaces which are adoptable to the present iron making situation in Indonesia and installing it to the electric furnace of the iron making plant in Indonesia for a demonstrative study on energy saving, etc. Spread/expansion of the electric furnace scrap preheater which is an excellent energy saving system targeted expansion of energy saving technology not only of Indonesia, but of ASEAN countries and Japan. In this fiscal year, remodeling of part of the system was made by change of flue gas flow for increasing the energy saving effect, and at the same time, a research study was made of a scrap reheater effective as a total system. Moreover, the paper investigated technical data/information in Japan and overseas. 3 figs., 9 tabs.

    2015-02-01

    The unexplained nature of dark matter and dark energy is a prominent reason for investigating physics beyond the standard model of particle physics (SM). Some extensions of the SM propose weakly interacting slim particles (WISPs). In an attempt to prove the existence of these particles, Light shining through the wall (LSW) experiments explore a very weak coupling between WISPs and photons (and viceversa). LSW experiments employ high-power lasers that provide a well defined flux of photons for the WISP-Photon conversion. The ALPS-I experiment at DESY in Hamburg was the first successful experiment with a high finesse optical resonator to enhance the laser power in a strong magnetic field in order to increase the photon to WISP conversion probability. The ALPS-II experimental concept adds a second optical cavity to also increase the reconversion probability. Both cavities are separated by a wall, amplify light at 1064 nm and share a common optical axis. Operating these two cavities inside 20 straightened HERA superconducting dipole magnets and using a transition edge sensor (TES) as a single photon detector will make the ALPS-II experiment almost three orders of magnitude more sensitive than its predecessor. Since photons, originating from reconverted WISPs in the regeneration cavity (RC) have 1064 nm wavelengths, the RC has to be locked to the production cavity (PC) with light of a different wavelength. Therefore frequency doubled PCs light will be used to lock the RC. This 532 nm light shall not arrive at the TES to prevent background noise. To achieve this, an optical attenuation system for wavelengths different from 1064 nm is required. In my thesis, the required attenuation was estimated and an optical setup was proposed and constructed and tested. It attenuates green photons by a factor of of 10 -18 and transmits 85% of the infrared photons. Furthermore the high finesse production cavity of ALPS-IIa was set up and characterized during this thesis. The PC reached

    Development is made of high energy-efficiency laser processing technology and high efficiency/high grade photon generation/control technology as laser light source, for the purpose of energy conservation/efficiency heightening of production processes which require a large amount of energy such as welding, joining, surface treatment, and particle fabrication. As to keyhole dynamics of the molten metal generated on the laser weld, construction of simulational mathematical models was started. Equipment to fabricate semiconductor ultrafine particles which become the core of quantum dot functional structures was designed to fabricate particles. In-situ optical measuring technology was studied of element/size of particles of below 30 nm in size by emission spectroscopy associated with the plasma irradiation. As tightly focusing all-solid-state laser technology, studied was the wavelength conversion method in which harmonics are generated four times as much as the fundamental wave due to high efficient generation of high power UV laser. Also studied were high laser strength, low optical losses, conditions for fostering high homogenity crystals. Technology for high accuracy processing of element surface was established.

    A research/development was conducted on technologies of photon applied measuring/photon applied processing/photon generation which are usable for heightening of reliability and maintenance efficiency of power generation facilities. In fiscal 1997, high melting-point metal particles were manufactured by high energy density laser for formation of high temperature and stabilized fine functional circuit. Further, a wavelength changeable ultra red laser light source was studied which can make in-situ measurement of gas concentration and components. A study was also made to examine the surface composition by measuring fluorescent X-rays emitted by radiating high intensity laser beam on the surface of material. A rod type and a slab type as a high-output complete-solidified laser are under development. There is also a development aiming at high speed/high quality photon processing such as high speed/high precision welding/cutting and laser joining. Besides, a study is being made of high energy pulse/high quality beam complete-solidified laser. The paper made a comprehensive survey of the trend of the photon measuring/monitoring technology, and made a systematical arrangement of the developmental subjects extracted. 142 refs., 357 figs., 62 tabs.

    In mammals, the circadian timing system drives rhythms of physiology and behaviour, including the daily rhythms of feeding and activity. The timing system coordinates temporal variation in the biochemical landscape with changes in nutrient intake in order to optimise energy balance and maintain metabolic homeostasis. Circadian disruption (e.g. as a result of shift work or jet lag) can disturb this continuity and increase the risk of cardiometabolic disease. Obesity and metabolic disease can also disturb the timing and amplitude of the clock in multiple organ systems, further exacerbating disease progression. As our understanding of the synergy between the timing system and metabolism has grown, an interest has emerged in the development of novel clock-targeting pharmaceuticals or nutraceuticals for the treatment of metabolic dysfunction. Recently, the pineal hormone melatonin has received some attention as a potential chronotherapeutic drug for metabolic disease. Melatonin is well known for its sleep-promoting effects and putative activity as a chronobiotic drug, stimulating coordination of biochemical oscillations through targeting the internal timing system. Melatonin affects the insulin secretory activity of the pancreatic beta cell, hepatic glucose metabolism and insulin sensitivity. Individuals with type 2 diabetes mellitus have lower night-time serum melatonin levels and increased risk of comorbid sleep disturbances compared with healthy individuals. Further, reduced melatonin levels, and mutations and/or genetic polymorphisms of the melatonin receptors are associated with an increased risk of developing type 2 diabetes. Herein we review our understanding of molecular clock control of glucose homeostasis, detail the influence of circadian disruption on glucose metabolism in critical peripheral tissues, explore the contribution of melatonin signalling to the aetiology of type 2 diabetes, and discuss the pros and cons of melatonin chronopharmacotherapy in

    Laboratory corrosion testing of candidate alloys—including Zr-4 and Zr-2.5Nb representing the target solution vessel, and 316L, 2304, 304L, and 17-4 PH stainless steels representing process piping and balance-of-plant components—was performed in support of the proposed SHINE process to produce 99Mo from low-enriched uranium. The test solutions used depleted uranyl sulfate in various concentrations and incorporated a range of temperatures, excess sulfuric acid concentrations, nitric acid additions (to simulate radiolysis product generation), and iodine additions. Testing involved static immersion of coupons in solution and in the vapor above the solution, and was extended to include planned-interval tests to examine details associated with stainless steel corrosion in environments containing iodine species. A large number of galvanic tests featuring couples between a stainless steel and a zirconium-based alloy were performed, and limited vibratory horn testing was incorporated to explore potential erosion/corrosion features of compatibility. In all cases, corrosion of the zirconium alloys was observed to be minimal, with corrosion rates based on weight loss calculated to be less than 0.1 mil/year with no change in surface roughness. The resulting passive film appeared to be ZrO2 with variations in thickness that influence apparent coloration (toward light brown for thicker films). Galvanic coupling with various stainless steels in selected exposures had no discernable effect on appearance, surface roughness, or corrosion rate. Erosion/corrosion behavior was the same for zirconium alloys in uranyl sulfate solutions and in sodium sulfate solutions adjusted to a similar pH, suggesting there was no negative effect of uranium resulting from fluid dynamic conditions aggressive to the passive film. Corrosion of the candidate stainless steels was similarly modest across the entire range of exposures. However, some sensitivity to corrosion of the stainless steels was

    Purpose: This work aimed at quantifying the gains in spatial resolution and noise that could be achieved when using resolution modelling based on a multi-ray approach and additionally the Statistical and Heuristic Noise Extraction (SHINE) method in human pinhole single photon emission tomography (PH-SPECT). Methods: PH-SPECT of two line phantoms and one homogeneous cylinder were recorded using parameters suited for studies of the human neck area. They were reconstructed using pinhole dedicated ordered subsets expectation maximisation algorithm including a resolution recovery technique based on 7 or 21 rays. Optionally, the SPECT data were SHINE pre-processed. Transverse and axial full widths at half-maximum (FWHM) were obtained from the line phantoms. The noise was quantified using the coefficient of variation (COV) derived from the uniform phantom. Two human PH-SPECT studies of the thyroid (a hot nodule and a very low uptake) were processed with the same algorithms. Results: Depending on the number of iterations, FWHM decreased by 30 to 50% when using the multi-ray approach in the reconstruction process. The SHINE method did not affect the resolution but decreased the COV by at least 20% and by 45% when combined with the multi-ray method. The two human studies illustrated the gain in spatial resolution and the decrease in noise afforded both by the multi-ray reconstruction and the SHINE method. Conclusion: Iterative reconstruction with resolution modelling allows to obtain high resolution human PH-SPECT studies with reduced noise content. The SHINE method affords an additional noise reduction without compromising the resolution. (orig.)

    This paper describes the hardware, firmware and software systems used in data acquisition for the NA61/SHINE experiment at the CERN SPS accelerator. Special emphasis is given to the design parameters of the readout electronics for the 40 m^3 volume Time Projection Chamber detectors as these give the largest contribution to event data among all the subdetectors: events consisting of 8 bit ADC values from 256 time slices of 200 k electronic channels are to be read out with order of ~100 Hz readout rate. As the data acquisition system is organized in `push data mode', i.e. local systems transmit data asynchronously, techniques of solving subevent synchronization is also discussed.

In this paper we report on the first successful integration of a large-scale optical cavity to boost the available power for WISP production in this type of experiments. The key elements are a frequency tunable narrow line-width continuous wave laser acting as the primary light source and an electronic feed-back control loop to stabilize the power build-up. We describe and characterize our apparatus and demonstrate the data analysis procedures on the basis of a brief exemplary run. (orig.)

    2009-01-01

    One of physics goals of the NA61/SHINE experiment is a measurement of hadron production cross sections from proton-Carbon interactions at 31GeV/c for the T2K experiment at J-PARC. A precise knowledge of differential cross sections for pion and kaon production is of importance for improving the accuracy of neutrino flux simulations. The NA61 detector has a large angular acceptance, full coverage of the T2K phase space region, and good particle identification. In this work the analyses of negatively charged pion production are presented. Two different methods of negative pion selection and corrections for detector effects are discussed. Finally, preliminary dn/dp distributions of negatively charged pion in p+C interactions at 31 GeV/c are presented.

    CERN Document Server

    Naskret, Michal

    The NA61/SHINE experiment at CERN is searching for the critical point in phase transition between quark-gluon plasma and hadronic matter. To do so we use the most precise apparatus - Time Projection Chamber. Its main task is to find trajectories of particles created in a relativistic collision. In order to improve efficiency of TPCs, we introduce calibration using radioactive krypton gas. Simulation of events in a TPC cham- ber through a decay of excited krypton atoms gives us a spectrum, which is later fitted to the model spectrum of krypton from a Monte-Carlo simulation. The data obtained in such a way serves us to determine malfunctioning electronics in TPCs. Thanks to the krypton calibration we can create a map of pad by pad gains. In this thesis I will de- scribe in detail the NA61 experimental setup, krypton calibration procedure, calibration algorithm and results for recent calibration runs

    The paper described the results of the survey of the fine ceramics technology field relating to the FY 1999 long-term energy technology strategy. The fine ceramics industry is a new industry for which the future development is expected. It has far-reaching effects on other industries. Japan has the advantage over other countries. As subjects to remarkably develop the industry, needed are the long-term basic preparation which promotes technology innovation such as the promotion of the fundamental/creative R and D, construction of an industry/university liaison system, and arrangement of the intellectual base. Preparation of the competitive environment and promotion of policies paying attention to the market are needed which make the development under the private control by creative study/corporate activities possible. Also important are the demonstration of leadership and secure international competitive force in the light of Japan's international position. For the private-control development, the role and course of various groups should be made clear from a long-term aspect. It is desirable that university/government will newly develop innovative technology, and industry will make the present technology force more developmental and competitive. Support from the nation is requested for researches large in scale. (NEDO)

    As to long-term energy technology strategy, the paper described the results of the FY 1999 survey of chemical/process technology. The future chemical technology should be transformed from the material production technology in which priority used to be given to convenience to new chemical technology in which the functions needed are to be created. The shortage of the developmental period and minimization of the waste are also desired by the use of new methods. For it, the industry/government/university should gather wisdom together and fulfil the requests from other industries of the country under the circumstances of the society which is aging, is decreasing in birthrate, and is being highly information-oriented. At the same time, the technology should be contributional to constructing the circulating type society which has environmental harmony. If not, it cannot be the technology which is recognized by the society. Efforts should be made for the fundamental technology development, technology to create the materials needed in the society, and development of new process technology to be recognized in the society. Further, the development of technology to meet the needs/restraints from the society should be promoted as seen in the environmental hormone. At the same time, the intellectual base should be prepared such as arrangement of the technology database for advancing smooth technology development. (NEDO)

    2017-01-01

    A detailed knowledge of the fragmentation cross sections of intermediate mass nuclei is of paramount importance to understand the propagation of cosmic rays in our Galaxy and to evaluate the background for dark matter searches with space-based cosmic-ray experiments such as AMS. Therefore, we suggest a one-week test run in 2018 with secondary ions to establish the capabilities of NA61/SHINE to measure fragmentation cross sections at isotope level. No major modifications to the experimental setup of NA61/SHINE are needed to perform this feasibility study. The experience gained during the test run will be used to formulate a comprehensive measurement campaign for cosmic-ray related fragmentation cross sections for the possible extension of the NA61/SHINE physics program beyond 2020. The test data on carbon-proton and oxygen-proton interactions at 13A GeV/c that we intend to collect during the proposed test run have already the potential to reduce the current cross section uncertainties.

    In the previous report of this series, a literature review was performed to assess the potential for substantial corrosion issues associated with the proposed SHINE process conditions to produce 99Mo. Following the initial review, substantial laboratory corrosion testing was performed emphasizing immersion and vapor-phase exposure of candidate alloys in a wide variety of solution chemistries and temperatures representative of potential exposure conditions. Stress corrosion cracking was not identified in any of the exposures up to 10 days at 80°C and 10 additional days at 93°C. Mechanical properties and specimen fracture face features resulting from slow-strain rate tests further supported a lack of sensitivity of these alloys to stress corrosion cracking. Fluid velocity was found not to be an important variable (0 to ~3 m/s) in the corrosion of candidate alloys at room temperature and 50°C. Uranium in solution was not found to adversely influence potential erosion-corrosion. Potentially intense radiolysis conditions slightly accelerated the general corrosion of candidate alloys, but no materials were observed to exhibit an annualized rate above 10 μm/y.

    Full Text Available Background The Support, Health Information, Nutrition, and Exercise (SHINE trial recently showed that a telephone adaptation of the Diabetes Prevention Program (DPP lifestyle intervention was effective in reducing weight among patients with metabolic syndrome. The aim of this study is to determine whether a conference call (CC adaptation was cost effective relative to an individual call (IC adaptation of the DPP lifestyle intervention in the primary care setting. Methods We performed a stochastic cost-effectiveness analysis alongside a clinical trial comparing two telephone adaptations of the DPP lifestyle intervention. The primary outcomes were incremental cost-effectiveness ratios estimated for weight loss, body mass index (BMI, waist circumference, and quality-adjusted life years (QALYs. Costs were estimated from the perspective of society and included direct medical costs, indirect costs, and intervention costs. Results After one year, participants receiving the CC intervention accumulated fewer costs ($2,831 vs. $2,933 than the IC group, lost more weight (6.2 kg vs. 5.1 kg, had greater reduction in BMI (2.1 vs. 1.9, and had greater reduction in waist circumference (6.5 cm vs. 5.9 cm. However, participants in the CC group had fewer QALYs than those in the IC group (0.635 vs. 0.646. The incremental cost-effectiveness ratio for CC vs. IC was $9,250/QALY, with a 48% probability of being cost-effective at a willingness-to-pay of $100,000/QALY. Conclusions CC delivery of the DPP was cost effective relative to IC delivery in the first year in terms of cost per clinical measure (weight lost, BMI, and waist circumference but not in terms of cost per QALY, most likely because of the short time horizon.

    This paper reports the result on R and D of the femtosecond technology in fiscal 1997. Ultrahigh-speed electronic technology is indispensable for industrial basic technologies supporting the advanced information society in the 21st century. Control technology of photonic and electronic states in a femtosecond region is essential. In R and D of metrological technology using ultra-short light-pulses, study was made on generating and controlling technology for ultra- short light/electron beam pulses. Ti-sapphire mode-locked laser was prepared, and it was found that time-fluctuation of mode-locked laser pulses is measurable up to 100 femtosecond level. As measures against an instability of gain-switching semiconductor laser, light injection from the outside was effective. The stable directivity of laser beam was obtained by regenerative amplifier, while less temperature variation of an optical switch was necessary to stabilize energy. To generate femtosecond high-intensity X-ray pulse by collision of laser and electron beams, it was confirmed that sub- picosecond synchronization is possible by RF and picosecond laser synchronization circuit. 48 refs., 89 figs., 11 tabs.

    2015-07-01

    Full Text Available This article deals with the work of two of the most prominent horror fiction writers in American history, namely Edgar Allan Poe and Stephen King. The focus of this study is put on the comparative approach while tracing the influence of Poe’s several chosen narratives in King’s novel called The Shining (1977. The chosen approach has uncovered that King’s novel embodies numerous characteristics, tendencies, and other signs of inspiration by Poe’s narratives. The Shining encompasses Poe’s tales such as “The Masque of the Red Death”, “The Fall of the House of Usher”, and “The Black Cat” which are shown to be pivotal aspects of King’s novel. The analysis has shown that the aforementioned King’s novel exhibits Shakespearean elements intertwined with Poe’s “Masque of the Red Death”, the Overlook Hotel to be a composite consisting of various Poesque references, and that The Shining’s protagonist is a reflection of autobiographical references to specific aspects of the lives of Poe and King themselves.

    Reflectivity of an object is a good parameter for surface finish. As the patient evaluates finishing as a function of gloss/reflectivity/shine an attempt is made here to evaluate changes in surface finish with custom made reflectometer. The aim of the present study was to study the effect of various procedures during orthodontic treatment on the shine of enamel, using a custom made reflectometer. Sixty one extracted premolars were collected and each tooth was mounted on acrylic block. Reflectivity of the teeth was measured as compared to standard before any procedure. One tooth was kept as standard throughout the study. Sixty teeth were acid etched. Reflectivity was measured on custom made reflectometer and readings recorded. Same procedure was repeated after debonding. Then 60 samples were divided into three groups: Group 1 - Tungsten Carbide, Group 2 - Astropol, Group 3- Sof-Lex disc depending upon the finishing method after debonding and reflectivity was measured. The mean percentage of reflectivity after acid etching was 31.4%, debonding 45.5%, Tungsten carbide bur finishing (Group 1) was 58.3%, Astropol (Group 2) 72.8%, and Sof-Lex disc (Group 3) 84.4% as that to the standard. There was statistically very highly significant (p Group 2> Group 1. The primary goal was to restore the enamel to its original state after orthodontic treatment. The methods tested in this study could not restore the original enamel reflectivity.

    Putative genes crtE, crtB, and crtI from Deinococcus wulumiqiensis R12, a novel species, were identified by genome mining and were co-expressed using the optimized Shine-Dalgarno (SD) regions to improve lycopene yield. A lycopene biosynthesis pathway was constructed by co-expressing these three genes in Escherichia coli. After optimizing the upstream SD regions and the culture medium, the recombinant strain EDW11 produced 88 mg lycopene g(-1) dry cell wt (780 mg lycopene l(-1)) after 40 h fermentation without IPTG induction, while the strain EDW without optimized SD regions only produced 49 mg lycopene g(-1) dry cell wt (417 mg lycopene l(-1)). Based on the optimization of the upstream SD regions and culture medium, the yield of the strain EDW11 reached a high level during microbial lycopene production until now.

    One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering aspects of such a setup, currently under development at CERN. One critical point, to achieve meaningful results, is the electromagnetic shielding between axion-emitter and -receiver cavity, which needs to be in the order of 300 dB to improve over existing experimental bounds. The RF leakage or electromagnetic crosstalk between both cavities must be well controlled and quantified during the complete duration of the experiment. A very narrow band (in the 10^-6 Hz range) homodyne detection method is used to reveal the axion signal from background thermal noise. The current status of the experiment is presented.

    The paper commented on current environmental changes in the LP gas industry and the measures for reinforcement of the physical constitution. When correction of the high cost structure in Japan is now the problem, waves of deregulation and rationalization reach to not only to LP gas but energy competitive with LP gas such as petroleum, electric power and town gas. With this, it is expected that LP gas will be faced with severe competition with other energy media. In the LP gas industry, business becomes more and more in number and smaller and smaller in scale as it extends downstream. Therefore, the resulting complicatedness in the distribution sector is the problem. It is necessary to realize scale profit in each distribution stage and to heighten productivity by expanding the scale in the retailing stage, especially. It is also important to tackle scale merit, improvement of productivity, and cost reduction by concentrating functions on either of wholesalers or retailers in every function of delivery, safety, free from each distribution stage.

    The uneven temporal distribution of domestic energy demand is a well-known phenomenon that is increasingly troublesome for energy infrastructures and sustainable or low carbon energy systems. People tend to demand energy, and especially electricity, at specific times of the day and they do not necessarily do so when the sun is shining or the wind is blowing. The potential value of demand response as a solution rests on understanding the nature of temporal energy demand and the timing of the i...

  11. Hadron Production measurements at the NA61/SHINE experiment for the T2K Neutrino Flux Prediction

    CERN Document Server

    Sgalaberna, Davide

    2015-01-01

    The largest source of uncertainty on the initial neutrino flux in modern accelerator neutrino ex- periments is the poor knowledge on the production of hadrons that decay into neutrinos. T2K is a long baseline neutrino experiment that aims to precisely measure the parameters of the PMNS ma- trix via the n m ! n e appearance and n m disappearance as well as to look for the first indication of CP violation in the leptonic sector. The required total systematic uncertainty on the neutrino flux as low as 5% can hopefully be achieved with high precision hadron production measurements, performed by the dedicated auxiliary NA61/SHINE experiment at the CERN SPS. Production of hadrons in 31 GeV/c proton interactions on carbon is measured with a thin target (4% of the nuclear interaction length) to study the primary interactions and with a T2K replica target (1.9 interaction length) to investigate re-interactions in the long target. The low statistic pilot data-set taken in 2007 was used to measure hadron multiplicities ...

    We report on the first successfull application of a new experimental technique to search for weakly interacting sub-eV particles (WISPs) coupling to photons. As part of the ALPS experiment located at DESY in Hamburg, this technique uses an optical resonator to enhance the power inside a HERA dipole magnet on the production side of a typical ''light shining through a wall''-experiment. We use a frequency doubled continuous-wave laser emitting 0.6 W of power at 532 nm that is stabilized to a linear optical resonator with 8 m length. On resonance we achieve a circulating power of 34 W within the magnet. With this we obtained sensitivities corresponding to a coupling strength of g{approx}5.10{sup -7} GeV{sup -1} for interactions of axion-like particles and photons. The experimental setup and possible improvements are described and compared with common experimental designs with pulsed lasers.

    Access to water and sanitation are important determinants of behavioral responses to hygiene and sanitation interventions. We estimated cluster-specific water access and sanitation coverage to inform a constrained randomization technique in the SHINE trial. Technicians and engineers inspected all public access water sources to ascertain seasonality, function, and geospatial coordinates. Households and water sources were mapped using open-source geospatial software. The distance from each household to the nearest perennial, functional, protected water source was calculated, and for each cluster, the median distance and the proportion of households within 1500 m of such a water source. Cluster-specific sanitation coverage was ascertained using a random sample of 13 households per cluster. These parameters were included as covariates in randomization to optimize balance in water and sanitation access across treatment arms at the start of the trial. The observed high variability between clusters in both parameters suggests that constraining on these factors was needed to reduce risk of bias. © The Author 2015.

    Evidence consistently shows that low education is associated with unhealthy behaviors. A recent study in behavioral economics argued that high time preferences - the tendency to prefer immediate gain to later reward - explain the limited self-control of individuals in making preventive health-related choices. The aim of this study was to examine the mediating effect of time preference on the associations between education and smoking, binge drinking and overweight in young and middle-aged adults living in a Japanese metropolitan area, using a quantitatively measured time discount rate. A population-based probabilistic sample of residents of 25-50 years of age living in four municipalities within Japanese metropolitan areas where economic disparity is relatively large was obtained from the Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE). Respondents answered the questionnaire items using a computer-aided personal instrument (CAPI). Data from 3457 respondents were used in this study. Time preferences measured as categorical responses were converted into a continuous number of time discount rates by using the maximum likelihood method. Smoking habit, binge drinking, and body mass index were regressed on educational attainment with demographics and other confounders. The mediating effects of the time discount rate were examined with the bootstrapping method. Results showed that the time discount rate did not mediate the association between education and binge drinking and BMI. Even for smoking, the mediating effect of time discount rate was quite limited, indicating that the proportion of total effect of education mediated was only 4.3% for men and 3.0% for women. The results suggest that modifying time preferences through educational intervention has only limited efficacy in closing disparities in health-related behaviors, and that other mediators fostered by schooling, such as knowledge/skills, group norms and supportive peers

  18. Shining LUX on isospin-violating dark matter beyond leading order

    Isospin-violating dark matter (IVDM) has been proposed as a viable scenario to reconcile conflicting positive and null results from direct detection dark matter experiments. We show that the lowest-order dark matter-nucleus scattering rate can receive large and nucleus-dependent corrections at next......-to-leading order (NLO) in the chiral expansion. The size of these corrections depends on the specific couplings of dark matter to quark flavors and gluons. In general the full NLO dark-matter-nucleus cross-section is not adequately described by just the zero-energy proton and neutron couplings. These statements...... are concretely illustrated in a scenario where the dark matter couples to quarks through scalar operators. We find the canonical IVDM scenario can reconcile the null XENON and LUX results and the recent CDMS-Si findings provided its couplings to second and third generation quarks either lie on a special line...

    2012-01-01

    A team at CERN has drawn inspiration from calorimetry methods developed for high-energy physics to create a new positron-emission tomography system for use in medical imaging, which they’ve dubbed AX-PET. With support from European and American laboratories*, the project is reaching fruition, as initial tests confirm its promise.   Snapshot of a “phantom”, a test object, surrounded by the AX-PET photon detectors. Positron-emission tomography (PET) is a medical imaging technique based on the matter-antimatter interaction that can provide a three-dimensional representation of the metabolic activity of an organ. To do so, radioactive marker molecules are first injected into the subject. As the marker decays, it emits positrons (antimatter particles), which are annihilated upon encountering electrons in the surrounding environment. The resulting flash, consisting of two photons, is detected by the PET machine. In conventional PET systems, it is impossible to improv...

  20. SAX J1808.4−3658, an accreting millisecond pulsar shining in gamma rays?

    We report the detection of a possible gamma-ray counterpart of the accreting millisec- ond pulsar SAXJ1808.4–3658. The analysis of ~6 years of data from the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (Fermi-LAT) within a re- gion of 15° radius around the position of the pulsar reveals a point gamma-ray source detected at a significance of ~6σ (Test Statistic TS = 32), with position compatible with that of SAXJ1808.4–3658 within 95% Confidence Level. The energy flux in the energy range between 0.6 GeV and 10 GeV amounts to (2.1 ± 0.5) × 10 -12 erg cm -2 s -1 and the spectrum is well-represented by a power-law function with photon index 2.1±0.1. We searched for significant variation of the flux at the spin frequency of the pulsar and for orbital modulation, taking into account the trials due to the uncertain- ties in the position, the orbital motion of the pulsar and the intrinsic evolution of the pulsar spin. No significant deviation from a constant flux at any time scale was found, preventing a firm identification via time variability. Nonetheless, the association of the LAT source as the gamma-ray counterpart of SAXJ1808.4–3658 would match the emission expected from the millisecond pulsar, if it switches on as a rotation-powered source during X-ray quiescence.

    The Fermi Large Area Telescope (LAT) discovered a new gamma-ray source near the Galactic plane, Fermi J0109+6134, when it flared brightly in 2010 February. The low Galactic latitude (b = -1.2{sup o}) indicated that the source could be located within the Galaxy, which motivated rapid multi-wavelength follow-up including radio, optical, and X-ray observations. We report the results of analyzing all 19 months of LAT data for the source, and of X-ray observations with both Swift and the Chandra X-ray Observatory. We determined the source redshift, z = 0.783, using a Keck LRIS observation. Finally, we compiled a broadband spectral energy distribution (SED) from both historical and new observations contemporaneous with the 2010 February flare. The redshift, SED, optical line width, X-ray obsorption, and multi-band variability indicate that this new Gev source is a blazar seen through the Galactic plane. Because several of the optical emission lines have equivalent width > 5 {angstrom}, this blazar belongs in the flat-spectrum radio quasar category.

  8. Giuseppe Castiglione (Lang Shining, precursor de la primera mundialización pictórico-arquitectónica

    2016-09-01

    Full Text Available La obra del hermano lego jesuita Giuseppe Castiglione (nombre chino, Lang Shining, 1688-1766, desarrollada en la China Qing, no fue suficientemente conocida sino hasta el siglo xx, y se ha investigado muy poco sobre su papel precursor de la primera mundialización artística. Su aproximación a China fue primordialmente de carácter apostólico, como consecuencia de la acción misional. Esta misión estuvo basada en un proceso inculturador fundamentado, a su vez, en el intercambio de las ciencias y las artes. Este artículo pone de manifiesto el riguroso conocimiento que sobre perspectiva matemática lineal había adquirido Castiglione en Europa, y la trascendencia que tuvo en la hibridación cultural y artística en la China del siglo xviii. Su posible repercusión en manifestaciones artísticas posteriores en otros territorios constituye el tema central del trabajo. Desde el punto de vista artístico, dada su privilegiada posición en la corte imperial, el artista jesuita jugó un papel decisivo en los nuevos métodos pictórico-arquitectónicos que se desarrollaron en la dinastía Qing. Sus murales, retratos, caballos, flores y pájaros, fueron elogiados y admirados por el emperador Qianlong, y mucho tiempo después por diseñadores y pintores europeos. Al simbolismo y la sensibilidad de la pintura asiática, Castiglione añadió el misterio del ilusionismo mágico que encierra la perspectiva matemática lineal europea, que contenía la llave y el secreto del conocimiento geométrico de Lang Shining. Sin embargo, sus efectos no fueron exclusivamente artísticos, sino que en muchos casos tuvieron una vigorosa dimensión apostólica. La dimensión religiosa que presuponemos en las pinturas de los artistas jesuitas fue una herramienta esencial en el proceso de inculturación; en este sentido, G. Castiglione usó la perspectiva no sólo como una técnica que gustaba a los emperadores, y fundamentalmente al emperador Qianlong, sino también como

    The impact of energy policy measures has been assessed with various appraisal and evaluation tools since the 1960s. Decision analysis, environmental impact assessment and strategic environmental assessment are all notable examples of progenitors of Regulatory Impact Assessment (RIA) in the assessment of energy policies, programmes and projects. This chapter provides overview of policy tools which have been historically applied to assess the impacts of energy policies, programmes and projects....

    In the framework of the National Debate on the energies in a context of a sustainable development some associations for the environment organized a debate on the nuclear interest facing the renewable energies. The first part presents the nuclear energy as a possible solution to fight against the greenhouse effect and the associated problem of the wastes management. The second part gives information on the solar energy and the possibilities of heat and electric power production. A presentation of the FEE (French wind power association) on the situation and the development of the wind power in France, is also provided. (A.L.B.)

  13. Stockholm Shines (Editorial

    Full Text Available I didn’t sleep much in Stockholm. The eight hour time difference and the jet lag completely messed me up, not to mention the 19 hours of daylight! But during the day when I was so tired, the content being presented at the conference and the people I met kept me buzzing and wide awake! It is always nice to find a group of people who are interested in the same things as you are, and to do so in a beautiful setting with great food and a friendly environment is all the better. In my opinion, the 5th EBLIP conference was the best yet! I returned to Canada inspired and intellectually stimulated.The EBLIP conference is one of the few times that those of us who work on the EBLIP journal have a chance to get together and talk in person. Our journal editors are situated in the U.K., Canada, and the United States, so our work is done primarily via e‐mail and the occasional conference call. Three of us made it to Stockholm (Alison, Lorie and myself, so it was great to touch base in person and have a drink or two together! We also got to see several members of the Editorial Advisory board, as well as those who write evidence summaries for us, or are involved in some other way. Meeting some of these people in person for the first time after a lengthy e‐mail relationship is quite a treat! The Editors took the opportunity at the conference to hold a user group meeting, inviting anyone who was interested to attend and provide us with feedback about the journal. To start we provided an update, which included the fact that the journal has over 2000 registered readers. Did you know that in just one month (May 25 – June 24, 2009 we had 4649 site visits; 3,678 of them unique? Most visits to the journal are from the United States, followed by Canada, Australia, and the U.K. But we have people accessing the journal from all over world, and now that we are tracking site traffic via Google Analytics, it is easy to see on a map where our readers reside. There was a good turnout for our user group, and a lively discussion. People told us what they valued about the journal, with much discussion focused on the evidence summaries. The evidence summaries are valued as a unique way to learn more about original research, and a few people noted that they will show evidence summaries to senior managers when the summary focuses on an aspect of practice that is being considered at their institution. One thing that came up time and time again was how to get more international content into the journal. As a result, we are going to try to incorporate reviews of non‐English language research. We also actively encourage people from anywhere in the world to submit articles or volunteer to serve on our Editorial Advisory Board or in some other capacity. The user group session was over before we knew it, but as always, I encourage all readers to provide us with feedback about how we can make EBLIP better.In this issue, there are a couple of things from the conference that I want to highlight. Andrew Booth proposes an International Association of EBLIP in a commentary; this was the result of an early morning open meeting held during the conference. As well, several conference attendees have provided reflections on their experiences, which you will find in the News section. For those who could not attend in person, this will give you a good sense of what happened at the conference from different perspectives. And finally, the first of what we hope are many papers resulting from presentations given at EBLIP5, an article by Michael Raynor is available in this issue. In a future issue we will have a Feature focused on all the keynote presentations that were given in Stockholm. As the days grow short here in my part of the world, I look back fondly on the long days in Stockholm this past summer, and am inspired to keep contributing to this international EBLIP community that continues to question our own models of practice in an effort to serve our local communities in the best way we possibly can.

    Argonne National Laboratory has developed a Mo-recovery and -purification system for the SHINE medical technologies process, which uses a uranyl sulfate solution for the accelerator-driven production of Mo-99. The objective of this effort is to reduce the processing time for the acidification of the Mo-99 product prior to loading onto a concentration column and concentration of the Mo-99 product solution. Two methods were investigated: (1) the replacement of the titania concentration column by an anion-exchange column to decrease processing time and increase the radioiodine-decontamination efficiency and (2) pretreatment of the titania sorbent to improve its effectiveness for the Mo-recovery and -concentration columns. Promising results are reported for both methods.

    O romance The Shining, de Stephen King, retrata os acontecimentos insólitos vividos pela família Torrance num hotel isolado nas montanhas do Colorado, EUA. A história de horror logo conquistou o público e tornou-se um bestseller, em especial após a adaptação para o cinema, com direção de Stanley Kubrick. Traduzida para o português brasileiro no mesmo ano de sua publicação nos Estados Unidos, a obra literária ganhou novas edições no Brasil desde então, embora mantendo a primeira tradução (Albu...

  16. Energy options. Preparing for an uncertain future

    International Nuclear Information System (INIS)

    Andrews, H.R.; Harvey, M.

    1988-02-01

    We must begin now to plan to replace fossil fuels as a major energy source. Few energy sources are capable of supplying the vast amount of energy required. The only options that can play a major role are coal, hydro-electricity, and nuclear. The soft energy options are not reliable: we cannot control the blowing of the wind or the shining of the sun; biomass is susceptible to disease. If we were to become too dependent on these we would be surrendering our energy system to the vagaries of nature. A strong electrical system is a cornerstone of energy security. Surplus capacity is often criticized, but a shortfall in supply will cause industrial chaos. Nuclear power is based on a sustainable resource supply, uses a proven technology, is economically competitive, and causes minimal harm to human populations and the environment

    The primary energy supply of Pakistan in the financial year 2009-10 was 63.088 million tonnes of oil equivalent (MTOE). Globally, renewable energies generation is around (19%) [1]. Pakistan has a yearly average solar energy shining potential of about 19 Mega Joules per square meter, with 7.6 hours per day with an average solar radiation of 5-7 kW h/(m 2 day). An alarming stage for the government to take serious steps to tackle energy demand, in vision to inclining oil markets, depletion of gas reserves, huge electricity demand and supply gap, lessening of forest reserves, calamity (floods, heavy rainfalls, earth quakes, melting of glaciers etc.), Kyoto bindings etc. All these factors are indicating for the transition towards renewable energy technologies.

    Measurements of hadron production in p+C interactions at 31 GeV/c are performed using the NA61/ SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data collected in 2009 using a graphite target with a thickness of 4% of a nuclear interaction length. Interaction and production cross sections as well as spectra of pi+/0, K+/-, p, K0S and Lambda are measured with high precision. These measurements are essential for improved calculations of the initial neutrino fluxes in the T2K long-baseline neutrino oscillation experiment in Japan. A comparison of NA61/SHINE measurements with predictions of several hadroproduction models is presented.

Project SHINE (Sanitation & Hygiene INnovation in Education is a grassroots participatory science education and social entrepreneurship model to engage youth and the wider community in the development of sustainable strategies to improve sanitation and hygiene. Methods Based in rural and remote Tanzania, this pilot study engaged pastoralist high-school students and communities in the development and evaluation of culturally and contextually relevant strategies to improve sanitation and hygiene. Using a train-the-trainer approach, key activities included teacher workshops, school-based lessons, extra-curricular activities, community events and a One Health sanitation science fair which showcased projects related to water, sanitation and hygiene in relation to human and animal health. The process and outcome of the study were evaluated through qualitative interviews and focus group discussions with diverse project participants, as well as pre- and post- questionnaires completed by students on knowledge, attitudes and practices concerning sanitation and hygiene. Results The questionnaire results at baseline and follow-up showed statistically significant improvements on key measures including a decrease in unhygienic behaviors, an increase in the perceived importance of handwashing and intention to use the toilet, and increased communication in the social network about the importance of clean water and improved sanitation and hygiene practices, however there were no significant changes in sanitation related knowledge.

    Remarkable innovations of the Japanese industry in various fields have been extracted and evaluated during the 50 post-war years. In this report, a method of capturing the innovations of industrial technology is examined. It is essential to clarify the social role of industrial technology, and the original views of this research are indicated by focusing on the innovation process in order to clarify the connections between those of mutual industry, technical management, man-power, and unique Japanese technology. The innovations achieved by the Japanese industry during post-war 50 years are classified into eight categories, i.e., automobiles, iron, aero-space/railways, machines, national land/energy, chemicals/fine ceramics, electronics/information/communication, and life, to clarify the technological progress in each field. In Japan, the industrial technology has been developed with learning from fundamental researches in Europe and the USA. In the future, it is necessary to independently develop industrial frontier. 4 figs., 47 tabs.

    Described herein are the reports presented to the industrial technology subcommittee, 17th symposium of NEDO projects. For development of high-efficiency industrial furnaces by high-temperature air combustion (including regenerative combustion), high-temperature air above 1000 degrees C is used, where carbon dioxide and NOX are possibly abated by 30% or more and 50%, respectively. The worldwide development is also described. For production of high-function ceramic materials at low temperature, the soft solution process is proposed for the in-situ production of these ceramic materials from the aqueous solution without using high temperature or high energy. For example, the high-functional ceramic material can be produced in-situ on a substrate by reacting the highly active aqueous solution with the substrate by a combination of, e.g., the hydrothermal and electrochemical reactions, without needing post-treatment under heating. For the marine biological technologies, deposition of living organisms is described. A geodome is developed for utilizing very deep (50m or deeper) underground spaces. It is a dome-shaped space supported by no strut, having dimensions of 50m in diameter and 30m high not to affect the surrounding environments, e.g., underground water. The techniques for creating advanced functional materials are developed by combining, e.g., laser, plasma, ion and magnetic field in diversified manners. (NEDO)

  8. Measurements of hadron yields from the T2K replica target in the NA61/SHINE experiment for neutrino flux prediction in T2K

    CERN Document Server

    AUTHOR|(CDS)2086777

    T2K is an accelerator-based long-baseline neutrino experiment in Japan. The main goal of the T2K experiment is a search for CP violation in the lepton sector by measuring electron (anti)neutrino appearance in a muon (anti)neutrino beam. Initial (anti)neutrino flux is produced in decays of hadrons which originate from the interactions and the re-interactions of a $30\\:$GeV proton beam with a $90\\:$cm long graphite target. Knowledge of the T2K neutrino flux is limited due to large hadron production uncertainties. A series of hadron production measurements were done to solve this problem, in the NA61/SHINE experiment at CERN. Measurements were performed with a proton beam and two target types: a thin graphite target and a replica of the T2K target. Work presented in this thesis concentrates on the T2K replica target data taken in 2010 and the development of the analysis and calibration software. The aim of these measurements is to fully constrain production of $\\pi^+$, $\\pi^-$, $K^+$, $K^-$ and $p$ coming from t...

    1999-01-01

    In this project a miniature photovoltaic energy system has been designed and developed, that may be used in remote areas and villages for lighting purposes. System sizing is the important part of the project because it affects the cost of the system. Therefore, first of all system sizing has been done. For conversion of dc voltage of the battery into ac voltage, an inverter has been designed. To charge the battery when the sun is not shining, a standby system has been developed using a bicycle and dynamo. To indicate the battery's state of charge and discharge, a battery monitoring circuit has also been developed. Similarly, to protect the battery from over discharging, a battery protection circuit has been designed. In order to measure how much energy is going from standby system to the battery, an efficient dc electronic energy meter has been designed and developed. The working of the overall system has been tested and found to give good performance. (author)

  10. 5'-Terminal AUGs in Escherichia coli mRNAs with Shine-Dalgarno Sequences: Identification and Analysis of Their Roles in Non-Canonical Translation Initiation.

    Directory of Open Access Journals (Sweden)

    Heather J Beck

    Full Text Available Analysis of the Escherichia coli transcriptome identified a unique subset of messenger RNAs (mRNAs that contain a conventional untranslated leader and Shine-Dalgarno (SD sequence upstream of the gene's start codon while also containing an AUG triplet at the mRNA's 5'- terminus (5'-uAUG. Fusion of the coding sequence specified by the 5'-terminal putative AUG start codon to a lacZ reporter gene, as well as primer extension inhibition assays, reveal that the majority of the 5'-terminal upstream open reading frames (5'-uORFs tested support some level of lacZ translation, indicating that these mRNAs can function both as leaderless and canonical SD-leadered mRNAs. Although some of the uORFs were expressed at low levels, others were expressed at levels close to that of the respective downstream genes and as high as the naturally leaderless cI mRNA of bacteriophage λ. These 5'-terminal uORFs potentially encode peptides of varying lengths, but their functions, if any, are unknown. In an effort to determine whether expression from the 5'-terminal uORFs impact expression of the immediately downstream cistron, we examined expression from the downstream coding sequence after mutations were introduced that inhibit efficient 5'-uORF translation. These mutations were found to affect expression from the downstream cistrons to varying degrees, suggesting that some 5'-uORFs may play roles in downstream regulation. Since the 5'-uAUGs found on these conventionally leadered mRNAs can function to bind ribosomes and initiate translation, this indicates that canonical mRNAs containing 5'-uAUGs should be examined for their potential to function also as leaderless mRNAs.

    We examined the association between socioeconomic position (SEP) and oral health, and the associations of economic difficulties in childhood and workplace-related factors on these parameters. Cross-sectional study. A total of 3201 workers aged 25-50 years, living in and around Tokyo, Japan, from the J-SHINE (Japanese study of Stratification, Health, Income, and Neighborhood) study. The response rate was 31.6%. Self-rated oral health (SROH)-A logistic regression model was used to estimate ORs for the association between poor SROH and each indicator of SEP (annual household income, wealth, educational attainment, occupation and economic situation in childhood). Multiple imputation was used to address missing values. Each indicator of SEP, including childhood SEP, was significantly inversely associated with SROH, and all of the workplace-related factors (social support in the workplace, job stress, working hours and type of employment) were also significantly associated with SROH. Compared with professionals, blue-collar workers had a significantly higher OR of poor SROH and the association was substantially explained by the workplace-related factors; ORs ranged from 1.44 in the age-adjusted and sex-adjusted model to 1.18 in the multivariate model. Poverty during childhood at age 5 and at age 15 was associated with poorer SROH, and these two factors seemed to be independently associated with SROH. We found oral health disparity across SEP among workers in Japan. Approximately 60% of the association between occupation and SROH was explained by job-related factors. Economic difficulties during childhood appear to affect SROH in adulthood separately from sex, age and the current workplace-related factors. Published by the BMJ Publishing Group Limited.

    Many individuals with obesity report over eating despite intentions to maintain or lose weight. Two barriers to long-term weight loss are reward-driven eating, which is characterized by a lack of control over eating, a preoccupation with food, and a lack of satiety; and psychological stress. Mindfulness training may address these barriers by promoting awareness of hunger and satiety cues, self-regulatory control, and stress reduction. We examined these two barriers as potential mediators of weight loss in the Supporting Health by Integrating Nutrition and Exercise (SHINE) randomized controlled trial, which compared the effects of a 5.5-month diet and exercise intervention with or without mindfulness training on weight loss among adults with obesity. Intention-to-treat multiple mediation models tested whether post-intervention reward-driven eating and psychological stress mediated the impact of intervention arm on weight loss at 12- and 18-months post-baseline among 194 adults with obesity (BMI: 30-45). Mindfulness (relative to control) participants had significant reductions in reward-driven eating at 6 months (post-intervention), which, in turn, predicted weight loss at 12 months. Post-intervention reward-driven eating mediated 47.1% of the total intervention arm effect on weight loss at 12 months [β = -0.06, SE(β) = 0.03, p = .030, 95% CI (-0.12, -0.01)]. This mediated effect was reduced when predicting weight loss at 18 months (p = .396), accounting for 23.0% of the total intervention effect, despite similar weight loss at 12 months. Psychological stress did not mediate the effect of intervention arm on weight loss at 12 or 18 months. In conclusion, reducing reward-driven eating, which can be achieved using a diet and exercise intervention that includes mindfulness training, may promote weight loss (clinicaltrials.gov registration: NCT00960414).

    Why does the Sun shine? Today we know the answer to the question and we also know that earlier answers were quite wrong. The problem of the source of solar energy became an important part of physics and astronomy only with the emergence of the law of energy conservation in the 1840s. The first theory of solar heat based on the new law, due to J. R. Mayer, assumed the heat to be the result of meteors or asteroids falling into the Sun. A different and more successful version of gravitation-to-h...

    A review is made about the consequences of the European directive on energy that entered into application in august 2000. It appears that most countries are opening their electricity and gas markets at a faster pace than required by the E.U. directive. European gas imports reached 480 Gm{sup 3} in 2000 and are expected to be over 700 Gm{sup 3} in 2015, so the question of the reliability of the gas suppliers has to be answered at the European level. The current time is marked by an increase of the complexity of the energy market that is due to different factors: 1) the delay in the implementation of European energy directives in France, 2) new arrangement is occurring in United-Kingdom in the energy sector, 3) the lack of a regulating authority in Germany, and 4) the difficulty of inter-connecting the different European energy networks. This transitory period may generate some economic imbalances and competition disturbances by allowing some enterprises to benefit from lower energy prices before others. (A.C.)

  17. Transverse momentum spectra of hadrons in p + p collisions at CERN SPS energies from the UrQMD transport model

    Science.gov (United States)

    Ozvenchuk, V.; Rybicki, A.

    2018-05-01

    The UrQMD transport model, version 3.4, is used to study the new experimental data on transverse momentum spectra of π±, K±, p and p bar produced in inelastic p + p interactions at SPS energies, recently published by the NA61/SHINE Collaboration. The comparison of model predictions to these new measurements is presented as a function of collision energy for central and forward particle rapidity intervals. In addition, the inverse slope parameters characterizing the transverse momentum distributions are extracted from the predicted spectra and compared to the corresponding values obtained from NA61/SHINE distributions, as a function of particle rapidity and collision energy. A complex pattern of deviations between the experimental data and the UrQMD model emerges. For charged pions, the fair agreement visible at top SPS energies deteriorates with the decreasing energy. For charged K mesons, UrQMD significantly underpredicts positive kaon production at lower beam momenta. It also underpredicts the central rapidity proton yield at top collision energy and overpredicts antiproton production at all considered energies. We conclude that the new experimental data analyzed in this paper still constitute a challenge for the present version of the model.

    A node in a solar-powered wireless sensor network (WSN) collects energy when the sun shines and stores it in a battery or capacitor for use when no solar power is available, in particular at night. In our scheme, each tiny node in a WSN periodically determines its energy budget, which takes into account its residual energy, and its likely acquisition and consumption. If it expects to acquire more energy than it can store, the data which has it has sensed is aggregated with data from other nodes, compressed, and transmitted. Otherwise, the node continues to sense data, but turns off its wireless communication to reduce energy consumption. We compared several schemes by simulation. Our scheme reduced the number of nodes forced to black out due to lack of energy so that more data arrives at the sink node.

However, the partnerships between private firms and universities have no fixed pattern, and keep changing dynamically. Business incubators increased to 627 rapidly, and mainly supported by municipal governments and universities. The U.S. has a well-established mechanism of technology transfer, and has succeeded in many cases. Not only universities but also national laboratories commit to technology transfer to venture businesses, and after starting businesses, entrepreneurs can use various hedging systems which are expected to play a role promoting the future technology innovation. The U.S. also has many advanced areas for sustainable technology innovation, like Silicon Valley, and these areas contain many supporting bodies to help new businesses. The activity of these bodies is very suggestive to Japanese local platforms promoting technology innovation and new local industry creation. Study was also made on the possibility of technology exchanges with overseas advanced areas. (NEDO)

    Researches have been conducted on deca-nano quantum integrating transistor substrate technologies, and developments were made on a three-dimensional device simulator which can be used in deca-nano domains, and a circuit simulator to have quantifying function transistors coexist with silicon semiconductor integrated circuits. The researches were intended to develop a simulator capable of analyzing properties of very small silicon and compound semiconductor devices in deca-nano domains. The researches discussed the applicability of conventional simulators, calculated quantum levels in a three-dimensional hetero structure, and resulted in development of an electron wave propagation simulator in optional two-dimensional shapes, a quantum Monte Carlo simulator, and a three-dimensional semiconductor device simulator with quantum correction. On the other hand, in order to estimate characteristics of a hybrid circuit in which single electron transistors coexist with conventional transistors such as CMOS transistors, a single electron hybrid circuit simulator was developed. The development indicated that a CMOS-SET fused memory is promising as a future LSI memory. 22 refs., 116 figs., 3 tabs.

    Study was made on the applicability of mechanical milling (MM) and mechanical alloying (MA) to Fe system alloys. Metastable austenitic stainless steels such as SUS316L and SUS304L form {alpha} phases by strain induced transformation due to MM, and are subjected to further plastic deformation. Nano-size fine structure was obtained through inverse transformation into austenite({gamma}) by heat treatment or high-temperature sintering of MM powder. Fine microduplex structure of 620nm in average crystal grain size was obtained for SUS316L. This material showed nearly 3.3 times higher 0.2% tensile proof stress, nearly 1.8 times higher tensile strength, and 35% higher elongation than conventional ingot steels. Solid solution powder of 12Cr-Mo-W ferritic steel was sintered by hot isostatic pressing (HIP) under low- temperature and ultrahigh-pressure conditions of 650degC and 588MPa. The as-HIP`ed sample and sample annealed at 800degC showed average {alpha} grain sizes of 33 and 50nm, respectively, and a strength twice as high as that of 12Cr steel. 97 refs., 60 figs., 18 tabs.

    Beam energy scan programs in heavy-ion collisions aim to explore the QCD phase structure at high baryon density. Sensitive observables are applied to probe the signatures of the QCD phase transition and critical point in heavy-ion collisions at RHIC and SPS. Intriguing structures, such as dip, peak and oscillation, have been observed in the energy dependence of various observables. In this paper, an overview is given and corresponding physics implications will be discussed for the experimental highlights from the beam energy scan programs at the STAR, PHENIX and NA61/SHINE experiments. Furthermore, the beam energy scan phase II at RHIC (2019–2020) and other future experimental facilities for studying the physics at low energies will be also discussed.

  12. Energy Budget: Earth's Most Important and Least Appreciated Planetary Attribute

    The energy budget involves more than one kind of energy. People can sense this energy in different ways, depending on what type of energy it is. We see visible light using our eyes. We feel infrared energy using our skin (such as around a campfire). We know some species of animals can see ultraviolet light and portions of the infrared spectrum. NASA satellites use instruments that can "see" different parts of the electromagnetic spectrum to observe various processes in the Earth system, including the energy budget. The Sun is a very hot ball of plasma emitting large amounts of energy. By the time it reaches Earth, this energy amounts to about 340 Watts for every square meter of Earth on average. That's almost 6 60-Watt light bulbs for every square meter of Earth! With all of that energy shining down on the Earth, how does our planet maintain a comfortable balance that allows a complex ecosystem, including humans, to thrive? The key thing to remember is the Sun - hot though it is - is a tiny part of Earth's environment. Earth's energy budget is a critical but little understood aspect of our planetary home. NASA is actively studying this important Earth system feature, and sharing data and knowledge about it with the education community.

    Measurements of hadron production in p + C interactions at 31 GeV/c are performed using the NA61/SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data collected in 2009 using a graphite target with a thickness of 4 % of a nuclear interaction length. Inelastic and production cross sections as well as spectra of π{sup ±}, K{sup ±}, p, K{sub S}{sup 0} and Λ are measured with high precision. These measurements are essential for improved calculations of the initial neutrino fluxes in the T2K long-baseline neutrino oscillation experiment in Japan. A comparison of the NA61/SHINE measurements with predictions of several hadroproduction models is presented. (orig.)

Record/preservation and collection/systematization of history of the industrial technology is useful for forming bases necessary for promotion of future research/development and international contribution. Museums and material halls are the fields for making comprehensive and practical activities. The data were made as one of the basic databases as the first step for promoting activities for examining the technical succession situation in a long term range continuously and systematically. In the classification of the data, the energy relation was divided into electric power, nuclear power, oil, coal, gas and energy in general. Others were classified into metal/mine, electricity/electronics/communication, chemistry/food, ship building/heavy machinery, printing/precision instrument, and textile/spinning. Moreover, the traffic relation was classified into railroad, automobiles/two-wheeled vehicles, airline/space, and ships. Items were also set of life relation, civil engineering/architecture, and general. The total number of the museums for the survey reached 208.

  15. The low-energy frontier of particle physics

    International Nuclear Information System (INIS)

    Jaeckel, Joerg

    2010-02-01

    Most embeddings of the Standard Model into a more unified theory, in particular the ones based on supergravity or superstrings, predict the existence of a hidden sector of particles which have only very weak interactions with the visible sector Standard Model particles. Some of these exotic particle candidates (such as e.g. ''axions'', ''axion-like particles'' and ''hidden U(1) gauge bosons'') may be very light, with masses in the sub-eV range, and have very weak interactions with photons. Correspondingly, these very weakly interacting sub-eV particles (WISPs) may lead to observable effects in experiments (as well as in astrophysical and cosmological observations) searching for light shining through a wall, for changes in laser polarisation, for non-linear processes in large electromagnetic fields and for deviations from Coulomb's law. We present the physics case and a status report of this emerging low-energy frontier of fundamental physics. (orig.)

    Zambelli, Laura; Popov, Boris

    T2K is a long baseline neutrino oscillation experiment on accelerator based in Japan, whose primary goal is a precise measurement of the $\\theta_{13}$ angle of the $P\\!M\\!N\\!S$ matrix. This measurement is possible through the appearance of electronic neutrinos out of a muonic neutrino beam, 300~km downstream after their creation point. Neutrinos are made by the decay in flight of unstable particles (pions, kaons, muons) produced by 31~GeV/c accelerated protons impinging onto a carbon target. Most of the neutrinos produced are of muonic-type, but a non-negligible amount of electronic neutrinos is also created, which will contribute to the dominant source of errors for the measurement of $\\theta_{13}$. In order to understand, and predict, this electronic contamination, a parallel hadroproduction experiment is used: NA61/SHINE at CERN reproduces the T2K beam conditions, and measures the kinematics of produced hadrons thanks to two types of target: thin and replica. The measurement of the K0S production is descri...

    In the recent years theoretical studies and astrophysical observations have confirmed that unknown constituents of our universe like dark matter may find its explanation not only at large-scale experiments at highest energies, but could also show up at the opposite energy scale. In many laboratories world-wide searches for axions, axion-like particles, hidden photons, chameleons or other so-called WISPs with masses below the eV scale are ongoing. Examples at DESY are the experiments ALPS ("Any Light Particle Search") and SHIPS ("Solar HIdden Photon Search"). At CERN CAST and OSQAR take data. In all these experiments new particles could manifest themselves in a very spectacular manner. Light would apparently shine through thickest walls. The results of a first generation of laboratory and astrophysics experiments will be summarized and plans for future enterprises be discussed

    This paper describes development of superconducting new function transistors. Fiscal 1997 as the final year of the project advanced improvement in such transistor-using processes as formation and micro-processing of superconducting thin films to show enhancement in characteristics of high-temperature superconducting transistors and possibility of their application utilizing their high speed motions. Furthermore, fundamental technologies were studied with an aim on junction transistors to be applied as circuits. For field effect transistors, evaluation was performed on critical current distribution of step-type particle boundary junction to make it possible to evaluate characteristics of hundreds of transistors. At the same time, a magnetic flux quantum parametron gate with three-layer structure was fabricated to identify its operation. In superconducting-base transistors, strong reflection was recognized on temperature dependence of permittivity of an Nb-doped strontium titanate substrate used for collectors, by which barrier height was reduced. In the junction transistor and circuit technology, isotropic ramp-edge junctions were fabricated, and so was a frequency divider circuit with single magnetic flux quantum mode operation for evaluating high-speed response characteristics. High time resolution current was observed successfully by using a high-temperature superconducting sampler system. 148 refs., 127 figs., 4 tabs.

    For the purpose of clarifying the course of promotion of the original/creative future R and D and contributing to selection of technical themes and working-out of developmental methods, survey was conducted paying visits to museums of industrial technology in Japan which evaluate/preserve/exhibit/utilize memorial goods, data, information pertaining to the industrial technology in Japan. Museums for survey were the following ten: Chiba Museum of Science and Industry; Garasu no Sato (Glass Village); Maizuru World Brick Museum; Museum of Industrial Technology; Numata Memorial Hall/Mitsutoyo Museum of Dimensional Metrology; Omachi Energy Museum; Sake Museum; Saint Juan Bautista Museum; Subway Museum; Textile Museum Yukari. One of the points of this survey was to survey the actual state of the experimental type exhibition. The experimental type exhibition, which is wide in sphere, seems to be effective since visitors can operate it, simulate it, feel its size and make scientific experiments. However, the museums are not necessarily satisfied with the present situation. (NEDO)

    Described herein are the FY 2000 results of development of cluster ion beams. This technology generates the strong ion beams of atom and molecule clusters, and irradiate them onto the solid surfaces, to create new materials or treat materials. It allows the nano-level treatment. The program for high-current cluster ion beam generation/irradiation technology for industrial purposes attains the target high-current beam of 500{mu}m. It is necessary to establish the optimum cluster size, irradiated energy and ion species for the highly functional surface treatment, for which applicable technologies, e.g., those related to time of flight and molecular dynamics, are developed. Studies on high-current, large-area irradiation technologies are started. The program for material processing technologies involves evaluation of crystalline defects formed during the beam implantation by photoluminescence spectroscopy, and studies on semiconductor surface processing technologies. The surface smoothening technology is investigated to reduce crystalline defects and stress-induced strains for difficult-to-process materials, e.g., SiC and diamond, and the good results are produced. The program for development of superflat/superhard thin film formation technology involves irradiation of the Ar ion beams during the deposition of C{sub 60}(fullerene), to produce the superhard thin film.

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

    Posterior cortical atrophy (PCA) is a clinicoradiologic syndrome characterized by progressive decline in visual processing skills, relatively intact memory and language in the early stages, and atrophy of posterior brain regions. Misdiagnosis of PCA is common, owing not only to its relative rarity and unusual and variable presentation, but also because patients frequently first seek the opinion of an ophthalmologist, who may note normal eye examinations by their usual tests but may not appreciate cortical brain dysfunction. Seeking to raise awareness of the disease, stimulate research, and promote collaboration, a multidisciplinary group of PCA research clinicians formed an international working party, which had its first face-to-face meeting on July 13, 2012 in Vancouver, Canada, prior to the Alzheimer's Association International Conference.

    We investigate the possibilities of searching for a self-conjugate polarizable particle in the self-interactions of light. We first observe that polarizability can arise either from the exchange of mediator states or as a consequence of the inner structure of the particle. To exemplify this second possibility we calculate the polarizability of a neutral bosonic open string, and find it is described only by dimension-8 operators. Focussing on the spin-0 case, we calculate the light-by-light scattering amplitudes induced by the dimension-6 and 8 polarizability operators. Performing a simulation of exclusive diphoton production with proton tagging at the LHC, we find that the imprint of the polarizable dark particle can be potentially detected at 5σ significance for mass and cutoff reaching values above the TeV scale, for √s=13 TeV and 300 fb{sup −1} of integrated luminosity. If the polarizable dark particle is stable, it can be a dark matter candidate, in which case we argue this exclusive diphoton search may complement the existing LHC searches for polarizable dark matter.

    On January 20th, 2011, NanoSail-D successfully deployed its sail in space. It was the first solar sail vehicle to orbit the earth and the second sail ever unfurled in space. The 10m2 sail, deployment mechanism and electronics were packed into a 3U CubeSat with a volume of about 3500cc. The NanoSail-D mission had two objectives: eject a nanosatellite from a minisatellite; deploy its sail from a highly compacted volume to validate large structure deployment and potential de-orbit technologies. NanoSail-D was jointly developed by NASA's Marshall Space Flight Center and Ames Research Center. The ManTech/NeXolve Corporation provided key sail design support. NanoSail-D is managed by Marshall and jointly sponsored by the Army Space and Missile Defense Command, the Space Test Program, the Von Braun Center for Science and Innovation and Dynetics Inc. The presentation will provide insights into sailcraft advances and potential missions enabled by this emerging in-space propulsion technology.

    2010-01-01

    We present a class of warped extra dimensional models whose flavor violating interactions are much suppressed compared to the usual anarchic case due to flavor alignment. Such suppression can be achieved in models where part of the global flavor symmetry is gauged in the bulk and broken in a controlled manner. We show that the bulk masses can be aligned with the down type Yukawa couplings by an appropriate choice of bulk flavon field representations and TeV brane dynamics. This alignment could reduce the flavor violating effects to levels which allow for a Kaluza-Klein scale as low as 2-3 TeV, making the model observable at the LHC. However, the up-type Yukawa couplings on the IR brane, which are bounded from below by recent bounds on CP violation in the D system, induce flavor misalignment radiatively. Off-diagonal down-type Yukawa couplings and kinetic mixings for the down quarks are both consequences of this effect. These radiative Yukawa corrections can be reduced by raising the flavon VEV on the IR brane...

    Xeroderma pigmentosum (XP) is a rare, autosomal recessive disorder of DNA repair characterized by sun sensitivity and ultraviolet (UV) induced skin and mucous membrane cancers. Described in 1874 by Moriz Kaposi in Vienna, nearly 100 years later James Cleaver in San Francisco reported defective DNA repair in XP cells. This eventually provided the basis for a mechanistic link between sun exposure, DNA damage, somatic mutations and skin cancer. XP cells were found to have defects in 7 of the proteins of the nucleotide excision repair pathway and in DNA polymerase eta. XP cells are hypersensitive to killing by UV and XP cancers have characteristic “UV signature” mutations. Clinical studies at NIH found a nearly 10,000-fold increase in skin cancer in XP patients under age 20 years demonstrating the substantial importance of DNA repair in cancer prevention in the general population. About 25 % of XP patients have progressive neurological degeneration with progressive loss of neurons, probably from DNA damage induced by oxidative metabolism which kills non-dividing cells in the nervous system. Interestingly, patients with another disorder, trichothiodystrophy have defects in some of the same genes as XP but they have primary developmental abnormalities without an increase in skin cancer.

    This paper describes R and D on creation technique of novel advanced enzymes. In fiscal 1997, a novel mutagenesis technique was developed to obtain more kinds of mutational genes by shuffling between clonal genes as compared with the previous homogeneous recombination. A genotype- and phenotype-linking technology was developed by expressing random motifs (peptide as components of the active site of protein) on bacteria, and by developing a single-motif protein library. Study was made on a selection system for functional molecules of catalytic activities in a gene level, and a selection system for function of signal transduction. Analysis and evaluation study on vitro experimental technology can be efficiently promoted by recognizing the fitness landscape of target protein molecules. As a result, instead of the conventional method which needs several cycles of mutation and screening of 3-4 week/cycle, an efficient method possible to obtain multiple mutants was established. Research work was also promoted by various organizations to develop an accelerated formation technology of bio-functions. 68 refs., 51 figs., 14 tabs.

    The paper described the fiscal 1997 results of the study of the condensation base precise structure control conducted as a technical development of materials to heighten efficiency of power generation facilities. Condensation base polymer is an important material which occupies most of the engineering plastics. The study is aimed at developing basic technologies on the molecular weight and regularity by which a remarkable improvement can be expected in performance of condensation polymerization/ring-opening polymerization polymer materials, polymerization catalyst which arbitarily controls the primary structure such as branch and end group structures, and development of the precision polymerization process. In the synthesis of ordered polymer by direct polycondensation, synthesis of ordered polyamide from asymmetric monomers is studied. In the synthesis of chemically selective polyamide by direct polymerization, polyamide with functional group is synthesized by polymerizing without protecting functional group the monomer with such functional group as causes side reaction in polymerization. In the synthesis of polyamide having the limited distribution of molecular weight, the molecular weight/distribution of polyamide are controlled by connectedly conducting polycondensation which is itself to be done successively. 91 refs., 72 figs., 43 tabs.

    This paper describes R and D of creation technology of original advanced materials in the R and D project of industrial science and technology. Although new material technology is dependent on the needs of a future society, it should correspond to a global environment preservation society, information-oriented society and aging society as observed based on the present social trend, and new materials superior in hot strength, light weight, corrosion resistance, decomposability, photo-function, magnetism, conductivity, bio-copying and adaptability are demanded. This project is in promotion since fiscal 1996 to develop formation technology of high-performance advanced new materials by precise molecular control of structure and production process of organic polymers and molecular assemblies. The research started on 4 themes such as advanced stimulus-response material, precision catalytic polymerization, condensed system structure control and multi-dimensional polymer structure. The research on molecule harmonizing material was added in fiscal 1997. In fiscal 1997, the general committee discussed a progress situation and next year research plan, and surveyed an overseas technology trend. 1 fig.

    Study was made on the design of experiments for confirming the technological and economical feasibility of commercial production of Mn nodules. An experimental sea area was selected considering Mn nodule characteristics such as concentration, continuity of nodule distribution and nodule size, and sea bottom topographic features such as flatness and exposed bed rock disturbing traveling of nodule collectors. The experimental plan was decided on the basis of the survey and study on an experimental scale, various requirements, weather and sea weather features of the sea area, and sea bottom conditions. Based on the experimental plan, various verification tests and simulation analyses were carried out, and functions of various equipment were confirmed. The conceptual design of a mining system assumed both pump-lift and air-lift systems, and yearly production rates of 2 and 3 million tons by 2 mining barges, and summarized main points of every system. As the evaluation result, the future direction of commercial production of Mn nodules was clarified to a certain extent. 5 figs., 21 tabs.

    1974-01-01

    The Detroit Energy Conference has highlighted the declining oil reserves, estimated worldwide at 95 billion tons vs. an annual rate of consumption of over 3 billion tons. The present problem is one of price; also, petroleum seems too valuable to be simply burned. New sources must come into action before 1985. The most abundant is coal, with 600 billion tons of easily recoverable reserves; then comes oil shale with a potential of 400 billion tons of oil. Exploitation at the rate of 55 go 140 million tons/yr is planned in the U.S. after 1985. More exotic and impossible to estimate quantitatively are such sources as wind, tides, and the thermal energy of the oceans--these are probably far in the future. The same is true of solar and geothermal energy in large amounts. The only other realistic energy source is nuclear energy: the European Economic Community looks forward to covering 60% of its energy needs from nuclear energy in the year 2000. Even today, from 400 mw upward, a nuclear generating plant is more economical than a fossil fueled one. Conservation will become the byword, and profound changes in society are to be expected.

    Most embeddings of the Standard Model into a more unified theory, in particular the ones based on supergravity or superstrings, predict the existence of a hidden sector of particles which have only very weak interactions with the visible sector Standard Model particles. Some of these exotic particle candidates (such as e.g. ''axions'', ''axion-like particles'' and ''hidden U(1) gauge bosons'') may be very light, with masses in the sub-eV range, and have very weak interactions with photons. Correspondingly, these very weakly interacting sub-eV particles (WISPs) may lead to observable effects in experiments (as well as in astrophysical and cosmological observations) searching for light shining through a wall, for changes in laser polarisation, for non-linear processes in large electromagnetic fields and for deviations from Coulomb's law. We present the physics case and a status report of this emerging low-energy frontier of fundamental physics. (orig.)

    In our directionally and continuously changing world, history still matters, and it does so in increasingly novel and important ways. Human adaptation to global change will rely heavily on robust baselines of historic environmental variability and detailed understanding of how both past and modern ecosystems have responded to both individual and multiple stressors. The question of global change has motivated an upsurge in paleoecological studies that span the late Quaternary and the modern era, and has inspired a growing consideration of time as a fundamental axis in ecology (1). A major challenge in developing pertinent ecological baselines remains how to fuse, into continuous time series, observations and experiments from living systems with paleoecological reconstructions from the same sites (2, 3). Tracing and disentangling complex responses to environmental stress from paleological to present-day communities is especially daunting; for example, how climate change; accelerated land use; and biological invasions are influencing the flows of water, nutrients, and energy. The paper by Terry and Rowe in PNAS (4) is a shining example of how modern ecology and paleoecology can be spliced together to decipher how ecological processes unfold over time scales inaccessible to direct observation or experimentation, and how they can be disrupted by human impacts.

    Kragh, Helge

    2016-12-01

    Why does the Sun shine? Today we know the answer to the question and we also know that earlier answers were quite wrong. The problem of the source of solar energy became an important part of physics and astronomy only with the emergence of the law of energy conservation in the 1840s. The first theory of solar heat based on the new law, due to J.R. Mayer, assumed the heat to be the result of meteors or asteroids falling into the Sun. A different and more successful version of gravitation-to-heat energy conversion was proposed by H. Helmholtz in 1854 and further developed by W. Thomson. For more than forty years the once so celebrated Helmholtz-Thomson contraction theory was accepted as the standard theory of solar heat despite its prediction of an age of the Sun of only 20 million years. In between the gradual demise of this theory and the radically different one based on nuclear processes there was a period in which radioactivity was considered a possible alternative to gravitational contraction. The essay discusses various pre-nuclear ideas of solar energy production, including the broader relevance of the question as it was conceived in the Victorian era.

    2014-01-01

    Study of energy and system size fluctuations of identified hadrons is one of the key goals of NA61/SHINE at the CERN SPS. Results may allow to discover the critical point (CP) of strongly interacting matter as well as to uncover properties of the onset of deconfinement (OD). But fluctuations exhibit numerous other sources starting from most basic ones like volume effects and conservation laws. NA49 seems to observe fluctuations related to CP in collisions of medium size nuclei at top SPS energy. However, this result will remain inconclusive until systematic data on energy and system size dependence will be available. Moreover, fluctuations in p+p as well as in Pb+Pb interactions should be better understood. In this contribution results on multiplicity fluctuations of identified hadrons in p+p interactions at the CERN SPS energies will be presented. The NA61 data will be compared with the corresponding results from central Pb+Pb collisions of NA49 in the common acceptance region of both experiments. Moreover, ...

    The aim of this report is to shine a light on the latest developments in the South African energy sector and to show that the energy sector is a favourable sector in South Africa for Dutch commercial involvement. Above all, an answer is given to the question why there is almost no Dutch export or investment in South Africa's energy sector and how we can boost more Dutch commercial involvement. The country has abundant coal reserves and this is one of the reasons why it can supply the cheapest electricity in the world. This also makes it very difficult for other primary energy products to compete with coal. But things are starting to change due to important external and internal facts. The current electricity crisis contributes the most to the changing energy landscape in South Africa and will therefore be discussed in detail. The first chapter will give an overview of the fossil and sustainable energy sector in South Africa. It will describe how the different energy sources contribute to the energy mix of the country. In the second chapter, the most important developments in the energy field will be introduced and discussed. There will be a focus on internal and external factors which influence developments in South Africa. A SWOT analyses will be presented to give an overview of what is important to keep in mind when one looks at the South African energy sector. Chapter three will give an answer to the question where the best opportunities are for Dutch companies to invest in, export to or cooperate within the South African energy sector. This report should be read in cooperation with the two market surveys that were conducted for the Netherlands Foreign Trade Agency (EVD) and the Dutch Embassy in Pretoria. Both for fossil as for the sustainable energy opportunities are abundant, this does not mean that market entry is very easy. Furthermore, some recommendations are given on how more Dutch involvement in the South African energy sector could be achieved

As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

  4. Soft energy vs nuclear energy

    Ando, Yoshio

    1981-01-01

    During the early 1960s, a plentiful, inexpensive supply of petroleum enabled Japanese industry to progress rapidly; however, almost all of this petroleum was imported. Even after the first oil crisis of 1973, the recent annual energy consumption of Japan is calculated to be about 360 million tons in terms of petroleum, and actual petroleum forms 73% of total energy. It is necessary for Japan to reduce reliance on petroleum and to diversify energy resources. The use of other fossil fuels, such as coal, LNG and LPG, and hydraulic energy, is considered as an established alternative. In this presentation, the author deals with new energy, namely soft energy and nuclear energy, and discusses their characteristics and problems. The following kinds of energy are dealt with: a) Solar energy, b) Geothermal energy, c) Ocean energy (tidal, thermal, wave), d) Wind energy, e) Biomass energy, f) Hydrogen, g) Nuclear (thermal, fast, fusion). To solve the energy problem in future, assiduous efforts should be made to develop new energy systems. Among them, the most promising alternative energy is nuclear energy, and various kinds of thermal reactor systems have been developed for practical application. As a solution to the long-term future energy problem, research on and development of fast breeder reactors and fusion reactors are going on. (author)

    Increased focus has been placed on the issues of energy access and energy poverty over the last number of years, most notably indicated by the United Nations (UN) declaring 2012 as the 'International Year of Sustainable Energy for All'. Although attention in these topics has increased, incorrect assumptions and misunderstandings still arise in both the literature and dialogues. Access to energy does not only include electricity, does not only include cook stoves, but must include access to all types of energy that form the overall energy system. This paper chooses to examine this energy system using a typology that breaks it into 3 primary energy subsystems: heat energy, electricity and transportation. Describing the global energy system using these three subsystems provides a way to articulate the differences and similarities for each system's required investments needs by the private and public sectors.

    Do Georgia needs nuclear energy? Nuclear energy is high technology and application of such technology needs definite level of industry, science and society development. Nuclear energy is not only source of electricity production - application of nuclear energy increases year-by-year for medical, science and industrial use. As an energy source Georgia has priority to extend hydro-power capacity by reasonable use of all available water resources. In parallel regime the application of energy efficiency and energy conservation measures should be considered but currently this is not prioritized by Government. Meanwhile this should be taken into consideration that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. The Nuclear energy application needs routine calculation and investigation. For this reason Government Commission is already established. But it seems in advance that regional nuclear power plant for South-Caucasus region would be much more attractive for future

    Energy consumption has developed significantly since the Second World War and population growth and improved living standards should see needs increasing even more. Traditional forecasts show that this energy consumption will continue to depend heavily on fossil energy. However, resources are limited and their use have a negative impact on the greenhouse effect and climate change. There is therefore a need to develop large quantities of renewable energy sources, to intensify energy saving programs and to pursue research in certain key areas

Do LDCs therefore consume less energy per capita than rich countries in the past? And is their economic growth associated with a lower growth in energy consumption? Can they "leapfrog" to a lower-carbon economy? I use data on energy consumption, prices, and gross domestic product for 76 countries to estimate the energy intensity of ...

    This paper is a survey report for fiscal 1999 on structuring of the circulation type economic society harmonizing with environment. In order for Japan in the 21st century to solve various problems while maintaining sustainable development of the industries and economy, structuring the industrial technology strategies is indispensable. In order to establish targets to structure the circulation type society harmonizing with environment, small targets were broken down and specific technological examples were extracted as seen from categories based on flows of goods and the policy aspects. Then, from the viewpoints of extrication from wastes, reduction of risks caused by harmful substances, and growth under suppression of the global warming, case studies were performed on policy aspects toward the year 2010. Based on these studies, images of the emphasizing strategies were prepared, that are built on three pillars of 'R', the reduction, reuse and recycling. Specific technological examples were extracted comprehensively and specifically from research and development themes in research institutions inside and outside Japan to prepare a fundamental material for establishing the small targets. Furthermore, the examples were classified from the aspects of the three Rs. Areas of technological development seeds and areas with fewer seeds were made clear successfully. (NEDO)

    For the Japanese industry to cope properly with the age of great competition and to secure the technology competitive force, it is indispensable to collect/analyze a lot of information and develop policies, that is, strategies, for industrial technology. For study of types of technology innovation system, a survey was conducted in FY 1999 of samples of products with comparatively high competitive force. Concept of the product concerned was examined in terms of the enterprise (person) which created the product, enterprise which commercialized it first in the world, etc. As to each of the technologies, factors to get a top share were analyzed. Based on the analyses, factors to get a large share were classified, and the relations with technology were analyzed. With 'Study of industrial technology strategy' issued in March 1999 as reference, 54 of the products of which the world share is more than 75% were extracted. In the table, about the items on creation of technology, technology was classified into the basic technology, similar technology, traditional technology, and combined technology. About the items on improvement/application, it was classified into improvement and usage development. The other items were classified into production technology, users, and development/production cooperation infrastructure. (NEDO)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of an aircraft technology field. In an aircraft field, since the major theme is application of new technologies to new airframe development, with joining in international cooperative development of aircraft, Japanese initiative development of airframes based on the domestic market demands and profitability should be started as early as possible. Because there is no airframe development by only one country including U.S.A., Japan is profitable to unite with some overseas companies, and invest selectively in specific leading fields. Positive technical support to safety, reliability, comfort and environment harmony are also important. More important theme than establishment of elementary technologies is preparation of an integrated flight demonstration system to expand application chances of development results, and preparation of various test facilities for tests required during development activities. Application of information technologies to the whole aircraft industry, and organic cooperation between the private and public sectors are also important. (NEDO)

    This paper describes a development of air cooling equipment for gas turbine combustion in a 1090-MW combined plant and a discussion on its cooling effect. An open-type gas turbine reduces its output when suction temperature rises. This is a characteristic for a combined plant with high heat efficiency not capable of exhibiting its ability in summer. As a result of testing cooling methods, water spraying nozzles utilizing latent evaporation heat of water were installed at a gas turbine suction opening. Effects of cooling the gas turbine combustion air resulted in reducing the gas turbine suction temperature by 1.8[degree]C as a result of water spray at an ambient temperature of 30[degree]C and a relative humidity of 60%, increasing the plant output by 12 MW as a result of cooling the suction air, and improving the heat efficiency by about 0.035%. The amount of ammonia used for reducing nitrogen oxide generation was reduced by 10.8 kg/hr. Under an assumption of experimenting the water spray in summer on a 15-hour per day basis for 50 days, a calculation indicates an annual economic effect of about 13.5 million yen. 8 figs., 8 tabs.

    Esan, A. A.

    2000-08-01

    Energy is an essential factor to economic and social development and improved standards of living in developing countries. Nigeria in particular. There is a strong need for greater energy efficiency in every sector of economy in order to reduce costs. enhance competitiveness, conserve energy resources and reduce environmental impacts associated with production, distribution and use of energy. Energy auditing and monitoring has a significant role in any energy management and conservation project. Energy auditing as an important part of industrial energy management on plant level, represents a complex of activities aiming at the efficient use of energy. The activities are undertaken by a team of experts who use a set of measuring instruments to monitor and evaluate all the necessary data to elaborate a package of recommendations on improvements in the field of energy efficiency and possible product quality. The inefficient conversion and use of energy have been identified as a central problem for all developing countries, Nigeria inclusive, since they all consume significantly higher amounts of energy per unit of GDP than OECD countries. This aggravates energy-related environmental problems and is also a burden on domestic resources and foreign exchange. Energy prices have risen drastically in many developing countries, while energy intensities remain high. Price changes alone are not rapidly translating energy efficiency improvements. Identifying and removing the obstacles to greater energy efficiency should be priority for government in developing countries. This is why the Energy Commission, an apex organ of government on Energy matters in all its ramifications is out to encourage relatively low-cost energy audits for the Textile industries - such audits can identify ''good house-keeping's' measures, such as simply process improvements, that reduce energy consumption and operating costs. This will be followed by the training of plant workers/energy managers

In a first part, the author addresses issues ranging from the development needs of a society to the energy assessment of a country, i.e.: nature and quantity of needs in services provided by energy, analysis of the required quantity of energy products needed to satisfy these needs, stages between primary resources and service delivery, description of the French consumption of available final energy products (per product and per economic sector). In the second part, he addresses energy supply, energy sectors and environmental issues, thus focusing on the front end of the energy system, i.e. ways of production from primary energy resources to final energy products: main physical characteristics and description of the different fissile, fossil and renewable energies, description of the main sectors of production of final energy products (fuels, electricity, heat) with a specific attention to electricity. In this part, local, regional and global environmental issues related to the exploitation of these energy sectors are discussed: sources of atmospheric pollution related to energy, relationship between energy and global warming, role of the different greenhouse gases emitted by these sectors, and quantitative analysis of these emissions. The third part addresses the economy of energy systems. The author proposes a cost assessment method which can be used for the production analysis as well as the economic analysis of a specific energy product. He also described external costs and profits, and methods to take those hidden costs and profits into account. Other economic tools are discussed and compared

    G.A. de Boer reacts to recently published criticism of his contribution to a report entitled 'Commentaar op het boek 'Tussen Kernenergie en Kolen. Een Analyse' van ir. J.W. Storm van Leeuwen' (Commentary on the book 'Nuclear Energy versus Coal. An Analysis by ir. J.W. Storm van Leeuwen), published by the Dutch Ministry of Economic Affairs. The contribution (Appendix B) deals with energy analyses. He justifies his arguments for using energy accountancy for assessing different methods of producing electricity, and explains that it is simply an alternative to purely economic methods. The energy conversion yield (ratio of energy produced to energy required) is tabulated for different sources. De Boer emphasises that his article purposely discusses among other things, definitions, forms of energy, the limits of the systems, the conversion of money into energy and the definition of the energy yield at length, in order to prevent misunderstandings.

    The current status was investigated of the above technology, and several matters were found to be important, which are the improvement of earthquake-proof performance, safety assessment, early-stage acquisition of information on earthquake, highly aseismic structures, inexpensive seismic isolation devices, prompt restoration, and the security of energy supply and materials transportation just after earthquake. Technologies that have to be developed before earthquake involve active vibration control, constant surveillance, management and maintenance of disaster preventing devices, preparation and updating of disaster-related databases, etc. Technologies need to be developed for real-time disaster control in case of earthquake, which involve instant-start vibration control devices, information gathering, airborne monitoring robots, rescue robots, etc. Also required are technologies for prompt assistance and recovery after earthquake, such as those for the physical soundness related diagnosis and assessment of structures, facilities, and machinery, and for their restoration, remedy, and reinforcement. What is required is the establishment of a comprehensive technology into which all the necessary element technologies are incorporated. Since coordination is necessary with other official projects being implemented in a unified way for an industrial area, this project will be effectively accomplished when it is also treated as an official project.

    With an objective to set up a system for full-scale lifetime education, a feasibility study has been performed on preparing new educational materials and performing seminars. The continuing education program developed by the Japan Society of Mechanical Engineers is intended to assist engineers studied under the new engineer system to accumulate actual work experience after having acquired the qualification, and motivate ability maintenance and self-enlightenment after having acquired the engineer qualification, mainly through the training meetings and lecture meetings held by the Japan Society of Mechanical Engineers. The education items in the major field course include dynamics of materials and machines, energy and flow, information and control, and design and production. The items in the general common course include presentation and communication, kinetics learned from actual cases, engineer ethics, product liability and product safety. The seminar was held for two days for engineers graduated from undergraduate departments and experienced in actual works for two years or longer as the object. The actual status survey related to the continuing education by corporations revealed that 83% of the corporations has implemented intra-corporation training, and encouraged positive participation to outside seminars.

    Industrial cavitation has been discussed in the previous reports on macroscopic issues such as foreign exchange rates. This paper transfers the viewpoint to substantial states of individual industries, and discusses the cavitation issue first on the automobile industry. Specifically, the paper explains positioning of the Japanese automobile industry in the whole Japanese industry, foreign trade, capital export, the histories/trends in advancements into overseas markets as seen from production in overseas countries, as well as trends and future of energy consumption in the subject industry. The Japanese automobile industry has given the position of the world`s largest car producing country to America after the Plaza agreement in 1985, with the disparity spreading even in 1995. There is a prediction that domestic production will stay almost flat up to the year 2000, and the total production including overseas production will show slight increase. It now has come to the times that roles of the overseas production are amplified increasingly larger in the years to come. These situations leave a number of future problems, such as violent market struggles having begun among the industrialized nations for overseas production in the Asian countries. 14 figs., 14 tabs.

    The above was conducted by Research Institute of Innovative Technology for the Earth (RITE). Worldwide collaboration is mandatory for the settlement of environmental problems for the earth, and RITE is positively promoting its interaction with research institutes abroad. In fiscal 1998, it sent research teams to government organizations and research institutes in Europe and America for studies there. A study in Europe involved the preparation of chemicals from CO2 by virtue of novel biotic reactions, and RITE's microbial molecular function laboratory plans to start a leading study in fiscal 1999. In relation with environmental impact reducing technologies using sunlight-aided photocatalysts, visits were paid to three research institutes in America. RITE itself has developed a powdered semiconductor catalyst and is engaged in the study of producing hydrogen by decomposition of water using solar energy. Concerning the production of saccharides out of farm wastes remaining unused, researches were made into the feasibility of joint studies with some advanced research institutes in America. Discussions were made about the performance- and stability-related improvement of enzymes usable for the decomposition of biomass, the analysis of biological environmental circumstances that substance yielding microbes find themselves in under anaerobic conditions, etc. (NEDO)

    The first term has performed research and development placing emphasis on that 'the basic study on membrane separation is to be performed systematically to elucidate governing factors in membrane separation'. With respect to water/ethanol separation by using the penetration gasifying method, it was indicated that excellent separation performance can be exhibited by using natural polymers having sugar chain skeleton as a raw material, and by controlling the membrane structure by means of membrane manufacturing methods. For enhancement of performance in water selective permeation type separation membrane, it was shown experimentally that it is important to select a membrane suitable for the object of separation and a separation method that uses the selected membrane. Regarding the water/ethanol separation, it was shown theoretically that the penetration gasifying method can save more energy than the conventional distillation method, where the development target was presented. It was recognized that impregnation type liquid membrane using crown ether can separate amino acid optical isomers. High separation performance was obtained in carbon monoxide/nitrogen separation by using fluid carrier that uses cuprous iodine/1-methyl imidazole. (NEDO)

    Described herein are the results of the study on possibility of research exchanges, conducted by Research Institute of Innovative Technology for the Earth (RITE) in FY 2000. For development of thin-film catalysts, HTE, a venture developing combinatorial chemistry application to catalysts, is a potential partner for the exchanges. One of the technical problems involved in underground sequestration of CO2 relates to evaluation of the reactions between CO2 injected under pressure and the surrounding rocks. It is a less site-specific theme, and preferably pursued through international networks. The RITE delegates have visited the British Geological Survey, Canada's Alberta Research Council, and US's Pennsylvania State University, Rice University and Chevron Petroleum, finding research exchange possibilities in all of these organizations for broad technical themes related to underground sequestration of CO2. For energy conversion technologies using biomass resources as the source materials, the potential partners for the research exchanges include Swedish Royal Institute of Technology, Belgium's Catholic University of Louvain and Spain's University of Zaragona which leads researches in production of gases from wastes and biomass.

    Hazardous ingredients in gases exhausted from diesel, refuse treatment facilities, etc. are becoming the problem. The development is expected of porous ceramic films which have functions of separation/purification at high temperature. By making good use of the technology to synthesize ceramic films with uniform through pores of several ten nm order and the technology to form 1D through pores of several ten - 100{mu} m order, the development of the following technologies were made and are in sight: enhancement of functions of gas separation/purification, function of catalyst-carrying to be given, porous film formation/base material fabrication. For the commercialization of high performance structure use ceramic parts, required is innovation of the production method by which the production cost is reduced without damaging the characteristics. Technologies were used of micro-fine raw materials, rapid sintering, texture assessment, analysis, etc., and study was made of cost reduction in high performance ceramic parts. For energy conservation by reducing the sintering temperature, the following were trially conducted: mechanical ironing, use of low grade raw material, use of superplastic reformation and forging, etc. (NEDO)

    For the enhancement of separation process efficiency and energy efficiency in the chemical industry, etc., basic technologies are developed involving high-performance separation membrane materials which are excellent in durability and usable in the field where separation by membranes has been impractical. The liquid mixtures subjected to separation are a neutral organic compound/water system, an acidic organic compound/water system, and a polar organic compound/water system; the gas mixtures subjected to separation are an oxygen/nitrogen system and a carbon monoxide/nitrogen system. After a 10-year/3-phase development endeavors, the initially intended goals are sufficiently achieved. Among those that have to be mentioned is the development of a nonaqueous separation membrane, a supported liquid membrane with amino acid optically active high performance separation capability, a high-precision evaluation unit for gas separation membrane characteristics, a selective permeation membrane with high-level oxygen and carbon monoxide carriers and reactivation technology, a high-performance ethanol separation membrane, a water/polar organic compound separation membrane, and a water/acetic acid separation membrane and stability providing technology. In particular, the water selective permeation membrane for a mixture of water and alcohol has already arrived at the stage of bench plant demonstration. (NEDO)

    Renewable energy sources have a small environmental impact and can be easily integrated within existing structures. Moreover, the use of renewable energy sources can contribute to achieve a zero emission of carbon dioxide by 2100, provided an efficient environmental policy during the next 40 years. This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

    Up to the present the production, transmission and distribution of energy has been considered mostly as a fragmented problem; at best only subsystems have been considered. Today the scale of energy utilization is increasing rapidly, and correspondingly, the reliance of societies on energy. Such strong quantitative increases influence the qualitative nature of energy utilization in most of its aspects. Resources, reserves, reliability and environment are among the key words that may characterize the change in the nature of the energy utilization problem. Energy can no longer be considered an isolated technical and economical problem, rather it is embedded in the ecosphere and the society-technology complex. Restraints and boundary conditions have to be taken into account with the same degree of attention as in traditional technical problems, for example a steam turbine. This results in a strong degree of interweaving. Further, the purpose of providing energy becomes more visible, that is, to make survival possible in a civilized and highly populated world on a finite globe. Because of such interweaving and finiteness it is felt that energy should be considered as a system and therefore the term 'energy systems' is used. The production of energy is only one component of such a system; the handling of energy and the embedding of energy into the global and social complex in terms of ecology, economy, risks and resources are of similar importance. he systems approach to the energy problem needs more explanation. This paper is meant to give an outline of the underlying problems and it is hoped that by so doing the wide range of sometimes confusing voices about energy can be better understood. Such confusion starts already with the term 'energy crisis'. Is there an energy crisis or not? Much future work is required to tackle the problems of energy systems.

    Energy resources, the basic input in every area of the economy, have a fundamental function for society's welfare. Traditional energy resources are, however, rapidly decreasing. Energy supply has been falling behind in meeting global demand, and is causing increased focus on efficiency and economy concepts in recent energy policies. Since the existing energy resources are not spread evenly among the countries, but instead are concentrated in certain regions and countries, a monopolistic situation arises. Equally, supply assurance is an issue, since the energy supply is held by certain regions and countries who have monopolistic pricing power. Both the EU and many other countries are studying how to marketize energy. This book focuses on the importance of energy and the problems posed by it. It will be useful for the academic community, related sectors and decision makers.

    Veziroglu, T N

    1979-02-01

    In a hydrogen system, hydrogen is not a primary source of energy, but an intermediary, an energy carrier between the primary energy sources and the user. The new unconventional energy sources, such as nuclear breeder reactors, fusion reactors, direct solar radiation, wind energy, ocean thermal energy, and geothermal energy have their shortcomings. These shortcomings of the new sources point out to the need for an intermediary energy system to form the link between the primary energy sources and the user. In such a system, the intermediary energy form must be transportable and storable; economical to produce; and if possible renewable and pollution-free. The above prerequisites are best met by hydrogen. Hydrogen is plentiful in the form of water. It is the cheapest synthetic fuel to manufacture per unit of energy stored in it. It is the least polluting of all of the fuels, and is the lightest and recyclable. In the proposed system, hydrogen would be produced in large plants located away from the consumption centers at the sites where primary new energy sources and water are available. Hydrogen would then be transported to energy consumption centers where it would be used in every application where fossil fuels are being used today. Once such a system is established, it will never be necessary to change to any other energy system.

  12. Energy consumption and energy prices

    International Nuclear Information System (INIS)

    Bentzen, J.

    1993-01-01

    Data are presented on energy consumption and energy prices related to a number of OECD (Organisation for Economic Co-operation and Development) lands covering the period 1951-1990. The information sources are described and the development of energy consumption and prices in Denmark are illustrated in relation to these other countries. The energy intensity (the relation between energy consumption and the gross national product) is dealt with. Here it is possible to follow development during the whole post-war period. It is generally understood that Denmark saved large amounts of energy after 1973-74 but, taken over the whole post-war period, savings and decline in energy-gross national product relations are less dramatic compared to conditions in other OECD countries. Energy coefficients or elasticities show the relative rise in consumption compared to the relative rise in gross national product (growth rate). This is shown to be typically unstable and an eventual connection with the amount of energy price increase and/or the growth rate of the national economy is considered. Results of Granger causuality tests on energy consumption, national income and energy prices are presented. Effective energy prices were very low in Denmark up to 1970 when they suddenly began to increase. Since the oil crisis Denmark's energy consumption has fallen whereas the other countries have used rather more energy than before. Effective promotion of energy savings must be seen in relation to the fact that the 1970 basis level of energy consumption and intensity was unusually high. The high effective energy prices have also encouraged energy savings in Denmark. (AB)

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

    The possibility of energy catastrophes in the production of energy serves to make estimation of the true social costs of energy production difficult. As a result, there is a distinct possibility that the private marginal cost curve of energy producers lies to the left or right of the true cost curve. If so, social welfare will not be maximized, and underconsumption or overconsumption of fuels will exist. The occurrence of energy catastrophes and observance of the market reaction to these occurrences indicates that overconsumption of energy has been the case in the past. Postulations as to market reactions to further energy catastrophes lead to the presumption that energy consumption levels remain above those that are socially optimal

    1982-06-01

    There seems to be a trend towards expecting energy conservation to be a panacea for the world's ills. In fact, a global perspective on energy needs shows that more, not less, energy is needed and technological innovation in energy sources is essential in order to meet the needs of more than just the developed countries. Energy-intensive technology is the amplification of our natural resources rather than their depletion. A fundamental bioethical principle must be established if we are to analyze and organize scientific evidence about hazards from currently feasible energy resources, and separate genuine from counterfeit claims to credibility. In particular, public fears about radiation hazards and radioactive waste disposal are influenced too much by rhetorical cleverness and forensic skills of a vociferous minority. Potential hazard management is ethically equitable only if it is proportioned to actual basic harm that can be identified and reduced by expenditures of human effort, time and money

    Intended as a primer on the relationship between the development and use of various energy resources and resulting ecological consequences, the book is designed for a course that can serve students with or without much background in the biological or physical sciences. A review is presented of the major concepts used in atmospheric science, the general picture of energy principles and laws, the status of energy resources both in the United States and worldwide, and an analysis of how questions of energy demand are approached. Three classes of energy sources are addressed: solar, biomass, and coal. The ecological impacts of carbon dioxide, acid deposition, petroleum, electrical power-generation, and nuclear technology are discussed. Also given is a discussion of alternative technologies in energy production

    1981-04-01

    Developments in the area of energy storage are characterized, with respect to theory and laboratory, by an emergence of novel concepts and technologies for storing electric energy and heat. However, there are no new commercial devices on the market. New storage batteries as basis for a wider introduction of electric cars, and latent heat storage devices, as an aid for solar technology applications, with satisfactory performance standards are not yet commercially available. Devices for the intermediate storage of electric energy for solar electric-energy systems, and for satisfying peak-load current demands in the case of public utility companies are considered. In spite of many promising novel developments, there is yet no practical alternative to the lead-acid storage battery. Attention is given to central heat storage for systems transporting heat energy, small-scale heat storage installations, and large-scale technical energy-storage systems.

    This Transportation Energy Project is comprised of four unique tasks which work within the railroad industry to provide solutions in various areas of energy conservation. These tasks addressed: energy reducing yard related decision issues; alternate fuels; energy education, and energy storage for railroad applications. The NIU Engineering and Technology research team examined these areas and provided current solutions which can be used to both provide important reduction in energy usage and system efficiency in the given industry. This project also sought a mode in which rural and long-distance education could be provided. The information developed in each of the project tasks can be applied to all of the rail companies to assist in developing efficiencies.

    2007-04-15

    From its rebirth in the early 1980s, the rate of development of wind energy has been dramatic. Today, other than hydropower, it is the most important of the renewable sources of power. The UK Government and the EU Commission have adopted targets for renewable energy generation of 10 and 12% of consumption, respectively. Much of this, by necessity, must be met by wind energy. The US Department of Energy has set a goal of 6% of electricity supply from wind energy by 2020. For this potential to be fully realized, several aspects, related to public acceptance, and technical issues, related to the expected increase in penetration on the electricity network and the current drive towards larger wind turbines, need to be resolved. Nevertheless, these challenges will be met and wind energy will, very likely, become increasingly important over the next two decades. An overview of the technology is presented.

  15. Energy knowledge

    1997-11-01

    James Thurber`s grandmother `lived the latter years of her life in the horrible suspicion that electricity was dripping invisibly all over the house`. The idea that electricity might leak from empty light sockets is both bizarre and at the same time strangely plausible. Delivered in a variety of forms, gas, electricity, oil, coal, wood etc.; energy permits countless services and is embodied in almost everything we find around us. Both everywhere, and nowhere, it remains a mysterious if not magical feature of everyday life. So the image of leaking light sockets is appealing not just because it is a quaintly ridiculous idea conjured up by a confused old lady but because it precisely articulates lingering uncertainty about the intangible qualities of this most pervasive resource. Taking the invisibility of energy as a point of departure, this paper explores the different kind of knowledge we have of energy use. Although the technologies of domestic energy measurement are familiar enough, we know what a meter looks like and we all get energy bills, it still requires an act of faith to believe in the `reality` of energy consumption. Those who have learned the official languages of energy efficiency have access to richer vocabularies of revealing terminology and can talk more confidently in terms of kilowatts, U values and the rest. But how do these different knowledge relate, and how do different ways of knowing energy influence perceptions of the possibilities and problems of energy conservation? In exploring these issues, the paper re-examines theories of energy and knowledge implicit in energy policy and energy related research. (au) 22 refs.

Comparisons are presented between the wind power performances and European Commission White Paper and Biomass action plan objectives. The sector covers the energy exploitation of all energy flows specifically supplied by the seas and oceans. At present, most efforts in both research and development and in experimental implementation are concentrated on tidal currents and wave power. 90% of today worldwide ocean energy production is represented by a single site: the Rance Tidal Power Plant. Ocean energies must face up two challenges: progress has to be made in finalizing and perfecting technologies and costs must be brought under control. (A.L.B.)

    A compact energy concept opposes the existing development course of energy supply. This concept does without projects for opening-up oil and gas occurrences in the Arctic and in offshore seas, and also without a further extension of nuclear energy. Energy consumption is to be stabilized in the long-run on today's level by a utilization of energy which is to be substantially improved in a technical and economic respect. Oil and gas are to be replaced by 'soft', regenerative, mainly decentralized energy sources, in the course of about 30 years time. Solar energy is to be used for heating and service water, biogas as motor fuel being generated primarily from reference which will come from agriculture and forestry. Wind and hydroelectric power are to be used for generating electricity. In the first part, concepts for the present and future energy policy are discussed, in the second part, a lot of figures are given, supporting the respective arguments. In the third part the relationships between social and energy-economic developments are pointed out. (UA) [de

    Geothermal energy has shown a revival for several years and should strongly develop in a near future. Its potentiality is virtually unexhaustible. Its uses are multiple and various: individual and collective space heating, heat networks, power generation, heat storage, heat exchanges etc.. Re-launched by the demand of renewable energy sources, geothermal energy has become credible thanks to the scientific works published recently which have demonstrated its economical and technical relevance. Its image to the public is changing as well. However, lot of work remains to do to make geothermal energy a real industry in France. Several brakes have to be removed rapidly which concern the noise pollution of geothermal facilities, the risk of bad results of drillings, the electricity costs etc. This dossier gives an overview of today's main research paths in the domain of geothermal energy: 1 - geothermal energy in France: historical development, surface and deep resources, ambitions of the French national energy plan (pluri-annual investment plan for heat generation, incentives, regional 'climate-air-energy' schemes), specific regulations; 2 - geothermal energy at the city scale - sedimentary basins: Ile-de-France 40 years of Dogger reservoir exploitation, potentialities of clastic reservoirs - the Chaunoy sandstones example; 3 - geothermal power generation: conventional reservoirs - the Bouillante model (Guadeloupe, French Indies); the Soultz-sous-Forets pilot plant (Bas-Rhin, France); the supercritical reservoirs - the Krafla geothermal area (Iceland).

Measuring instruments varies from a simple watt-meter to more sophisticated microprocessor control devices. The negative effects...... that fossil fuels induce on our environment has forced us to research renewable energy such as sunlight, wind etc. This new environmental awareness has also helped us to realize the importance of monitoring and controlling our energy use. The main purpose in this research is to introduce a more sophisticated...... but affordable way to monitor energy consumption of individuals or groups of home appliances. By knowing their consumption the utilization can be regulated for more efficient use. A prototype system has been constructed to demonstrate our idea....

    This paper develops economic definitions of energy quality for individual fuels and energy aggregates. There are use- and exchange-value concepts, as well as marginal and total measures, of energy quality. A factor augmentation or quality coefficients approach corresponds to the use-value definition while indicators based on distance functions and relative prices are exchange-value based definitions. These indicators are identical when the elasticity of substitution between fuels is infinity but diverge or cannot be computed for other interfuel elasticities of substitution. When the elasticity of substitution is zero only the quality coefficients approach is defined. I also show that 1) the ratio of an energy volume index to aggregate joules cannot be considered a complete indicator of aggregate energy quality as it does not account for quality changes in the component fuels 2) demand curve integrals do not provide information on relative use-values or fuel qualities when the elasticity of substitution is unity or less.

    Each of the major energy markets for oil, coal, natural gas, biofuels and electricity has its own character. But markets are dependent on each other in an often complicated way. This interconnection has become even more complex since the market for emissions trading began in Europe in 2005. This report describes the current situation of the different energy markets but also the relationships between them, and some possible future scenarios. The oil market is global, but is dominated by a few producing countries. Coal is traded on the international market with good competition and over time probably a stable price. Other markets are more regional or even local. One example is the natural gas market. In the current situation of natural gas is not particularly important for Sweden's energy supply, but very much so in a European perspective. There may be repercussions also in Sweden. The gas price ups and downs are important for the price of emission rights and electricity. Biofuel markets ranging from global markets, such as ethanol, to regional or local markets, depending on processing. Only with the creation of a single trading venue, Nordpool was a common pricing of electricity possible in the Nordic region. In the near future we will have a common electricity market covering at least the Nordic region and northwestern Europe. This does not mean that prices will become equalized, for that further expansion of the transmission capacity is needed. It is possible to imagine several scenarios for future energy markets, but the interaction between the different markets will persist. To develop appropriate instruments is of great importance to achieve the political objectives in the energy field the next decade

    This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are considered. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined. Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR. Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given. The authors also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text. This book will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers

    mankind's anticipated energy needs for as long as the sun shines and the rain falls. Moreover, TWRs can naturally retain their efficiently-expended fuel for century length time-scales, so that they intrinsically pose minimal safety and security transportation hazards in addition to being full-scale carbon-free energy sources. This paper describes how TWRs could help move the global energy economy to a more sustainable footing. An economic case and potential impacts on the global energy system are explored. The paper also provides an overview of the practical engineering embodiment of the TWR, new computational tools we have developed for modeling TWRs, the degradation of the plutonium vector in used fuel from TWRs and advanced technological options for re-purposing fuel to extract more of its potential energy.

    Full Text Available Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhouse-gas (GHG emissions. Geothermal energy is the thermal energy stored in the underground, including any contained fluid, which is available for extraction and conversion into energy products. Electricity generation, which nowadays produces 73.7 TWh (12.7 GW of capacity worldwide, usually requires geothermal resources temperatures of over 100 °C. For heating, geothermal resources spanning a wider range of temperatures can be used in applications such as space and district heating (and cooling, with proper technology, spa and swimming pool heating, greenhouse and soil heating, aquaculture pond heating, industrial process heating and snow melting. Produced geothermal heat in the world accounts to 164.6 TWh, with a capacity of 70.9 GW. Geothermal technology, which has focused for decades on extracting naturally heated steam or hot water from natural hydrothermal reservoirs, is developing to more advanced techniques to exploit the heat also where underground fluids are scarce and to use the Earth as a potential energy battery, by storing heat. The success of the research will enable energy recovery and utilization from a much larger fraction of the accessible thermal energy in the Earth’s crust.

It would already be very difficult to halve the consumption of fossil fuels in France in 2050, without a swift and profound change in our energy-consumption choices (in particular in transport) and a considerable research effort. To divide it by four seems unrealistic, since France, unlike other countries, has already benefited from the transition from electricity produced from fossil fuels to nuclear electricity which does not emit CO 2 . A major evolution in energy, in Europe and throughout the World, is inevitable in the course of the century. To prevent this from being too violent and painful, a process of fundamental research and technological development should be launched forthwith, in all fields of energy production, storage and use, with a large effort supported by major research programmes. Some recommendations are given for the main research fields that should be: capture and long term storage of CO 2 , energy savings in transport, energy supply to large cities and nuclear power plant enhancement, hydrogen storage, wind energy and its unavailability problem, use of forest resources, photovoltaic electricity in rural and isolated regions, temporary storage of electricity

    2009-01-01

    There are 5 different ways of harnessing ocean energy: tides, swells, currents, osmotic pressure and deep water thermal gradients. The tidal power sector is the most mature. A single French site - The Rance tidal power station (240 MW) which was commissioned in 1966 produces 90% of the world's ocean energy. Smaller scale power stations operate around the world, 10 are operating in the European Union and 5 are being tested. Underwater generators and wave energy converters are expanding. In France a 1 km 2 sea test platform is planned for 2010. (A.C.)

The government will have then to decide of an energy programming bill which will be submitted to the Parliament at the beginning of the year 2014. 30 main propositions have emerged of the decentralised debates. One of them is the ecological taxation which raise the question of the gas oil and petrol taxation. The current environmental taxes are for almost three quarters of them taxes on energy consumptions and mainly on fossil energies. The Economic, Social and Environmental Council, gives his opinion on the way to find resources to ensure the ecological and energy transition while reducing the public deficit of the State. (O.M.)

    1991-01-01

    One form of renewable energy production involves the growing of energy coppice on agricultural land. It is important as it can be grown on those areas of agricultural land which are surplus to agricultural production. Hence it can be seen as an alternative farm crop, and as such, a possible solution to the problem of agricultural surpluses as well as providing a source of energy. Studies have indicated that up to one million hectares of land surplus to agricultural production may be suitable for growing energy coppice. However, its development as an agricultural crop will only happen if it can be produced at costs competitive with alternative fuels and there is a reliable and long term market offering good returns.

    2004-01-01

    World energy demand is constantly rising. This is a legitimate trend, insofar as access to energy enables enhanced quality of life and sanitation levels for populations. On the other hand, such increased consumption generates effects that may be catastrophic for the future of the planet (climate change, environmental imbalance), should this growth conform to the patterns followed, up to recent times, by most industrialized countries. Reduction of greenhouse gas emissions, development of new energy sources and energy efficiency are seen as the major challenges to be taken up for the world of tomorrow. In France, the National Energy Debate indeed emphasized, in 2003, the requirement to control both demand for, and offer of, energy, through a strategic orientation law for energy. The French position corresponds to a slightly singular situation - and a privileged one, compared to other countries - owing to massive use of nuclear power for electricity generation. This option allows France to be responsible for a mere 2% of worldwide greenhouse gas emissions. Real advances can nonetheless still be achieved as regards improved energy efficiency, particularly in the transportation and residential-tertiary sectors, following the lead, in this respect, shown by industry. These two sectors indeed account for over half of the country CO 2 emissions (26% and 25% respectively). With respect to transportation, the work carried out by CEA on the hydrogen pathway, energy converters, and electricity storage has been covered by the preceding chapters. As regards housing, a topic addressed by one of the papers in this chapter, investigations at CEA concern integration of the various devices enabling value-added use of renewable energies. At the same time, the organization is carrying through its activity in the extensive area of heat exchangers, allowing industry to benefit from improved understanding in the modeling of flows.

    This article gives a general overview of the past and present development of geothermal energy worldwide and a more detailed one in Switzerland. Worldwide installed electrical power using geothermal energy sources amounts to 8900 MW el . Worldwide utilization of geothermal energy for thermal applications amounts to 28,000 MW th . The main application (56.5%) is ground-coupled heat pumps, others are thermal spas and swimming pools (17.7%), space heating (14.9%), heating of greenhouses (4.8%), fish farming (2.2%), industrial uses (1,8%), cooling and melting of snow (1.2%), drying of agricultural products (0.6 %). Switzerland has become an important user of geothermal energy only in the past 25 years. Earlier, only the exploitation of geothermal springs (deep aquifers) in Swiss thermal baths had a long tradition, since the time of the Romans. Today, the main use of geothermal energy is as a heat source for heat pumps utilizing vertical borehole heat exchangers of 50 to 350 meters length. 35,000 installations of this type with heating powers ranging from a few kW to 1000 kW already exist, representing the highest density of such installations worldwide. Other developments are geostructures and energy piles, the use of groundwater for heating and cooling, geothermal district heating, the utilization of draining water from tunnels and the project 'Deep Heat Mining' allowing the combined production of heat and electric power

    The objective of the Symposium for Public Awareness on Energy was to provide an information exchange among the members of the technical community and the public, civic, fraternal, service, and labor organizations on timely energy-related issues. The 1977 symposium was oriented toward state and local governmental officials in the southeastern states. Since it is these officials who have the responsibility for the development and actualization of local energy strategies, the program was directed toward providing information which would be of help to them in considering energy plans. The symposium presentations featured speakers who are recognized in many facets of the energy field. A variety of views were expressed and a number of policy alternatives were suggested. It is hoped that the presentations provided the motivation for the audience to return to their respective communities with a new and expanded perspective regarding energy issues and policies. The private and public organizations represented at the symposium can continue to provide pertinent information to those who are interested. A separate abstract was prepared for each of the 9 presentations.

    Research and development in the field of energy technologies was and still is a rational necessity of our time. However, the current point of main effort has shifted from security of supply to environmental compatibility and safety of the technological processes used. Nuclear fusion is not expected to provide an extension of currently available energy resources until the middle of the next century. Its technological translation will be measured by the same conditions and issues of political acceptance that are relevant to nuclear technology today. Approaches in the major research establishments to studies of regenerative energy systems as elements of modern energy management have led to research and development programs on solar and hydrogen technologies as well as energy storage. The percentage these systems might achieve in a secured energy supply of European national economies is controversial yet today. In the future, the Arbeitsgemeinschaft Grossforschungseinrichtungen (AGF) (Cooperative of Major Research Establishments) will predominantly focus on nuclear safety research and on areas of nuclear waste disposal, which will continue to be a national task even after a reorganization of cooperation in Europe. In addition, they will above all assume tasks of nuclear plant safety research within international cooperation programs based on government agreements, in order to maintain access for the Federal Republic of Germany to an advancing development of nuclear technology in a concurrent partnership with other countries.

    Large areas of the desert southwest are currently developed or being evaluated for construction of utility-scale renewable energy projects. These projects include numerous solar and wind energy facilities some of which will be massive. Unfortunately, peer-reviewed scientific publications are not yet available to evaluate the potential effects of solar-based utility-scale renewable energy development (USRED) on any species of wildlife, including amphibians and reptiles (herpetofauna). Scientific publications on the effects of wind-based USRED and operation (USREDO) are focused almost exclusively on flying wildlife including birds and bats. To the best of our knowledge the only publications on the effects of wind-based USREDO on herpetofauna are three publications on desert tortoise ecology at a wind energy facility near Palm Springs, California. Those studies suggested that not all effects of USREDO were detrimental in the short-term. However, additional research is required to determine if wind energy operation is compatible with conservation of this long-lived species over longer periods of time.

    The wind energy or eolic energy is a consequence of solar energy, the one which is absorbed by the atmosphere and is transformed into energy of movement of large bulks of air. In this process the atmosphere acts as the filter to the solar radiation and demotes the ultraviolet beams that result fatal to life in the Earth. The ionosphere is the most external cap and this is ionized by means of absorption process of ultraviolet radiation arising to the Sun. The atmosphere also acts as a trap to the infrared radiation, it that results from the continual process of energetic degradation. In this way, the interaction between Earth - Atmospheres, is behaved as a great greenhouse, maintaining the constant temperatures, including in the dark nights. Processes as the natural convection (that occur by the thermodynamic phenomenon), equatorial calmness, trade winds and against trade winds and global distribution of the air currents are described. The other hand, techniques as the transformation of the wind into energy and its parameters also are shown

    This set of questions is based on an inquiry from the years 1987 to 1989. About 250 people af all age groups - primarily, however, young people between 16 and 25 years of age - were asked to state the questions they considered particularly important on the subject of nuclear energy. The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    In a first part, the author proposes an overview of technological developments in the field of power production. He outlines that technological advances may increase assessments of oil and gas reserves but that the associated costs might be too high to keep on exploiting these resources. The problem is almost the same for coal for which the associated costs concern the reduction of pollution and the sequestration and storage of carbon emissions. Nuclear energy avoids this issue of emissions and researches aim at the development of fusion reactors (ITER project) which still are an economic challenge because of their much higher cost in comparison with fission reactors. The author comments the development of renewable energies which however will not be able to replace thermal and nuclear production to face the constant increase of energy consumption. In the second part, the author evokes the various advances in energy production for transports: fuel cells, energy storage, hydrogen storage, and emergence of a hydrogen economy. He finally evokes applications to military propulsions (ground vehicles, marine propulsion, and aircraft propulsion)

    Manzella A.

    2015-01-01

    Full Text Available Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhouse-gas (GHG emissions. Geothermal energy is stored in rocks and in fluids circulating in the underground. Electricity generation usually requires geothermal resources temperatures of over 100°C. For heating, geothermal resources spanning a wider range of temperatures can be used in applications such as space and district heating (and cooling, with proper technology, spa and swimming pool heating, greenhouse and soil heating, aquaculture pond heating, industrial process heating and snow melting. Geothermal technology, which has focused so far on extracting naturally heated steam or hot water from natural hydrothermal reservoirs, is developing to more advanced techniques to exploit the heat also where underground fluids are scarce and to use the Earth as a potential energy battery, by storing heat. The success of the research will enable energy recovery and utilization from a much larger fraction of the accessible thermal energy in the Earth’s crust.

  16. Intermittently renewable energy, optimal capacity mix and prices in a deregulated electricity market

    International Nuclear Information System (INIS)

    Milstein, Irena; Tishler, Asher

    2011-01-01

    This paper assesses the effect of intermittently renewable energy on generation capacity mix and market prices. We consider two generating technologies: (1) conventional fossil-fueled technology such as combined cycle gas turbine (CCGT), and (2) sunshine-dependent renewable technology such as photovoltaic cells (PV). In the first stage of the model (game), when only the probability distribution functions of future daily electricity demand and sunshine are known, producers maximize their expected profits by determining the CCGT and PV capacity to be constructed. In the second stage, once daily demand and sunshine conditions become known, each producer selects the daily production by each technology, taking the capacities of both technologies as given, and subject to the availability of the PV capacity, which can be used only if the sun is shining. Using real-world data for Israel, we confirm that the introduction of PV technology amplifies price volatility. A large reduction in PV capacity cost increases PV adoption but may also raise the average price. Thus, when considering the promotion of renewable energy to reduce CO 2 emissions, regulators should assess the behavior of the electricity market, particularly with respect to characteristics of renewable technologies and demand and supply uncertainties. - Research Highlights: → This paper assesses the effect of intermittently renewable energy on generation capacity mix and market prices. → We consider two generating technologies: (1) conventional fossil-fueled technology such as CCGT and (2) sunshine-dependent renewable technology such as photovoltaic cells (PV). →Using real-world data for Israel, we confirm that the introduction of PV technology amplifies price volatility. → A large reduction in PV capacity cost increases PV adoption but may also raise the average price.

    Very high speed electronics technology is indispensable for the creation of industrial base technology which supports high grade informatizing in the 21st century. The state of light and electronics is controlled in the femto-second time domain. As to the development of femto-second light pulse generation/transmission technology, mode synchronous semiconductor laser was manufactured using the strain quantum well structure aiming at heightening profit, and the repeated frequency, 166GHz, was achieved. Relating to the pulse compression element, exciton photonic band was newly designed. A technology of coding was also studied. As to the development of technology of femto-second light pulse control/distribution, shortening of the wavelength down to 1.5{mu}m and a possibility of femto-second domain high speed response were indicated by the combined double quantum well structure. The quantitative measurement of spin relaxation characteristics was successfully made. By the Mach-Zehnder light switch, obtained was the world`s fastest light switching characteristic. To realize the femto-second class very high speed element, conditions were grasped on the crystal growth of Sb based ultra thin films operating in the 1.5{mu}m zone by studying the quantum well using transition among sub-bands. 242 refs., 280 figs., 12 tabs.

    Three major concerns face mankind's future: the impending energy crisis as caused by the depletion of the world's fossil fuel reserves, world atmospheric pollution as caused by the burning of these fuels, and mankind's destruction if the vast energy contained in nuclear weapons stockpiles is released in a global conflict. This paper describes an ambitious, combined solution to these problems by the use of deep underground detonations of thermonuclear devices/bombs to provide a virtually pollution free, world energy source into the far distant future, while achieving a significant increase in mutual trust between the superpowers and all nations. The key is believed to be thermonuclear geothermal stimulation to produce the electrical power needed for a hydrogen economy

    The designated successor to fossil fuels is nuclear fission/fusion and that turns out to be problematic. Alternative Energy Systems have great potential but political forces seem to be hampering their development and introduction. The technologies are flexible in their use and scale of operation. The learning curve will not be short but neither will it be as long and as costly as nuclear power. It is time that this is recognised and some serious rethinking takes place in what presently passes for energy policies both in the industrialised countries and in the Third World. Alternative energy systems are defined and some of them which are relevant to the United Kingdom are discussed. (author)

    The purpose of the Energy Deskbook is to serve as a convenient reference to definitions of energy-related terms and descriptions of current and potential energy sources and their utilization. The material is presented at a low technical level with emphasis on general principles, which are not difficult to understand, rather than technology. The entries vary in length from a few lines to several pages, according to circumstances. As a general rule, each topic is defined and outlined in the first paragraph; this may be followed by a more detailed treatment, as required. An important feature of the Deskbook is the use of boldface (heavy) type for cross references. Words in the text set in boldface are the titles of articles where the particular subjects are described.

    Geothermal energy is the natural heat of the earth. It represents an inexhaustible source of energy. In many countries, which are mostly located within the geothermal belts of the world, geothermal energy is being used since many decades for electricity generation and direct heating applications comprising municipal, industrial and agricultural heating. Outside the geothermal anomalous volcanic regions, hot ground water from deep rock formations at temperatures above 70 o C is used for process heat and space heating. Low prices for gas and oil hinder the development of geothermal plants in areas outside positive geothermal anomalies; the cost of drilling to reach depths, where temperatures are above 50 o C to 70 o C, is high. The necessary total investment per MW th installed capacity is in the order of 5 Mio- DM/MW th (3 Mio $/MW th ). Experience shows, that an economic break even with oil is reached at an oil price of 30$ per barrel or if an adequate bonus for the clean, environmentally compatible production of geothermal heat is granted. Worldwide the installed electric capacity of geothermal power plants is approximately 6 000 MW e . About 15 000 MW th of thermal capacity is being extracted for process heat and space heat. The importance of the terrestrial heat as an energy resource would be substantially increased, if the heat, stored in the hot crystalline basement could be extracted at economical production costs. Geothermal energy is a competitive energy source in areas with high geothermal gradients (relative low cost for drilling) and would be competitive in areas with normal geothermal gradients, if a fair compensation for environmental implications from fossil and nuclear power production would be granted.

    Bioenergy systems can provide an energy supply that is environmentally sound and sustainable, although, like all energy systems, they have an environmental impact. The impact often depends more on the way the whole system is managed than on the fuel or on the conversion technology. The authors first describe traditional biomass systems: combustion and deforestation; health impact; charcoal conversion; and agricultural residues. A discussion of modern biomass systems follows: biogas; producer gas; alcohol fuels; modern wood fuel resources; and modern biomass combustion. The issue of bioenergy and the environment (land use; air pollution; water; socioeconomic impacts) and a discussion of sustainable bioenergy use complete the paper. 53 refs., 9 figs., 14 tabs

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

    Research and development was conducted of a technology for manufacturing an ultrathin polycrystalline silicon solar cell capable of efficiency enhancement and cost reduction earlier than the types of polycrystalline solar cells now available on the market. In this fiscal year, a silicon melt/solidification experimenting apparatus was built for manufacturing high-quality silicon ingots. Using an apparatus with its performance similar to the newly built one, a preliminary experiment was conducted involving high-purity silicon ingot manufacturing. In the experiment, boron was added to 75 kg of silicon for semiconductor devices so that its resistivity may be 0.5 ohm-cm. The silicon was melted in a quartz mold, and then subjected to unidirectional coagulation at 0.13 mm/min that started at the bottom to proceed upward. The result was a silicon ingot 44 cm times 44 cm times 17 cm (height). The ingot thus obtained exhibited 0.4-0.8 ohm-cm in resistivity distribution. Solar cells produced from the ingot showed a conversion rate of 16.9%. (NEDO)

    The ovulatory activity in the livestock depends on the readiness of nutritious energy with relationship to its use for the nursing. During the early nursing the cup of increment in the production of milk exceeds to the consumption of food, the difference in the energy consumption of the diet with relationship to the energy used for production is a negative energy balance. During the first weeks of nursing this reaches their maximum and it diminishes slowly with the increment in the consumption of dry matter. This first metabolic sign is in an increment in the pulses of hormone luteinizant that acts as and stimulate for the ovary and that with a great readiness of insulin, it takes to the ovarian follicles to respond to the stimulus. The sub-alimentation seems to affect the hypothalamic function and ovarian. The return to the positive energy balance in cows highly producers can be accelerated by the consumption of protected fat. The functions of the lipids are to provide energy for normal maintenance and production, to serve as source of essential fatty acids and eat payee of liposoluble vitamins. The importance of the addition of vegetable fat is that this is not degraded in the rumen but rather it is digested in its entirety in abomasa and absorbed in intestine. The addition of a source of Ca to diets with fats promotes the formation of insoluble soaps achieving that the fat doesn't inhibit the fiber fermentation; the chloride of Ca to be of high solubility in water it is completely ionized in rumen and it is more efficient in the formation of insoluble soaps of Ca. The addition of fat in the diet bears increase in the production of N microbial, inhibition of methane formation, increase and change in population of bacteria and mushrooms. The efficiency of the fat is superior when sources of fatty acids of long chain are used, the employment of these, in its protected form, in a diet, stimulates the number of follicles and it increases its size.

    The vast number of species making up natural communities, and the myriad interactions among them, pose great difficulties for the study of community structure, dynamics and stability. Borrowed from other fields, network analysis is making great inroads in community ecology and is only now being applied to host-parasite interactions. It allows a complex system to be examined in its entirety, as opposed to one or a few components at a time. This review explores what network analysis is and how it can be used to investigate parasite ecology. It also summarizes the first findings to emerge from network analyses of host-parasite interactions and identifies promising future directions made possible by this approach.

    The circadian clock provides essential timing information to ensure optimal growth to prevailing external environmental conditions. A major time-setting mechanism (zeitgeber) in clock synchronization is light. Differing light wavelengths, intensities, and photoperiodic duration are processed for the clock-setting mechanism. Many studies on light-input pathways to the clock have focused on Arabidopsis thaliana. Photoreceptors are specific chromic proteins that detect light signals and transmit this information to the central circadian oscillator through a number of different signalling mechanisms. The most well-characterized clock-mediating photoreceptors are cryptochromes and phytochromes, detecting blue, red, and far-red wavelengths of light. Ultraviolet and shaded light are also processed signals to the oscillator. Notably, the clock reciprocally generates rhythms of photoreceptor action leading to so-called gating of light responses. Intermediate proteins, such as Phytochrome interacting factors (PIFs), constitutive photomorphogenic 1 (COP1) and EARLY FLOWERING 3 (ELF3), have been established in signalling pathways downstream of photoreceptor activation. However, the precise details for these signalling mechanisms are not fully established. This review highlights both historical and recent efforts made to understand overall light input to the oscillator, first looking at how each wavelength of light is detected, this is then related to known input mechanisms and their interactions. © 2017 John Wiley & Sons Ltd.

    Structure-performance relationships gained by studying catalysts at work are considered the key to further development of catalysts underlined here by a brief overview on our research in this area. The partial oxidation of methane to hydrogen and carbon monoxide over Pt- and Rh-based catalysts and the total combustion of hydrocarbons demonstrate the importance of structural identification of catalysts in its working state and the measurement of the catalytic performance at the same time. Moreover, proper cell design is a key both here and in liquid phase reactions including preparation or high pressure reactions. In several cases structural changes during preparation, activation and reaction occur on a subminute scale or the catalyst structure varies inside a reactor as a result of temperature or concentration gradients. This, additionally, requires time and spatial resolution. Examples from time-resolved QEXAFS studies during the partial oxidation of methane over Pt- and Rh-based catalysts demonstrate some of the recent developments of the technique (use not only of Si(111) but also Si(311) crystals, angular encoder, full EXAFS spectra at subsecond recording time, and modulation excitation spectroscopy). In order to obtain spectroscopic information on the oxidation state inside a microreactor, scanning and full field X-ray microscopy with X-ray absorption spectroscopic contrast were achieved under reaction conditions. If a microbeam is applied, fast scanning techniques like QEXAFS are required. In this way, even X-ray absorption spectroscopic tomographic images of a slice of a microreactor were obtained. The studies were recently extended to spatiotemporal studies that give important insight into the dynamics of the catalyst structure in a spatial manner with subsecond time-resolution.

    2008-01-01

    This phenomenological study focuses on the experience of career satisfaction among registered nurses. Potential participants were asked, "Do you love your work as a nurse?" A random sample of eight nurses who answered yes to this question was questioned further during semistructured conversations. Conversations were recorded and transcribed. Data collected were in the form of descriptions of times during the participants' careers when they felt most professionally fulfilled. Through narrative and poetic analysis, themes of "upholding the vulnerable," "going the extra mile," and "attending to the essential ordinary" were identified. Nurse educators play an important role facilitating career satisfaction for registered nurses. Practical implications for continuing education for educators and practicing nurses are addressed.

    Sleep is essential to cognitive function and health in humans, yet the ultimate reasons for sleep-i.e. 'why' sleep evolved-remain mysterious. We integrate findings from human sleep studies, the ethnographic record, and the ecology and evolution of mammalian sleep to better understand sleep along the human lineage and in the modern world. Compared to other primates, sleep in great apes has undergone substantial evolutionary change, with all great apes building a sleeping platform or 'nest'. Further evolutionary change characterizes human sleep, with humans having the shortest sleep duration, yet the highest proportion of rapid eye movement sleep among primates. These changes likely reflect that our ancestors experienced fitness benefits from being active for a greater portion of the 24-h cycle than other primates, potentially related to advantages arising from learning, socializing and defending against predators and hostile conspecifics. Perspectives from evolutionary medicine have implications for understanding sleep disorders; we consider these perspectives in the context of insomnia, narcolepsy, seasonal affective disorder, circadian rhythm disorders and sleep apnea. We also identify how human sleep today differs from sleep through most of human evolution, and the implications of these changes for global health and health disparities. More generally, our review highlights the importance of phylogenetic comparisons in understanding human health, including well-known links between sleep, cognitive performance and health in humans. © The Author(s) 2016.

  15. Globular Clusters Shine in a Galaxy Lacking Dark Matter

    2018-04-01

    You may have seen recent news about NGC 1052DF2, a galaxy that was discovered to have little or no dark matter. Now, a new study explores what NGC 1052DF2 does have: an enigmatic population of unusually large and luminous globular clusters.Keck/LRIS spectra (left and right) and HST images (center) of the 11 clusters associated with NGC 1052DF2. The color images each span 1 1. [van Dokkum et al. 2018]An Unusual DwarfThe ultra-diffuse galaxy NGC 1052DF2, originally identified with the Dragonfly Telescope Array, has puzzled astronomers since the discovery that its dynamical mass determined by the motions of globular-cluster-like objects spotted within it is essentially the same as its stellar mass. This equivalence implies that the galaxy is strangely lacking dark matter; the upper limit set on its dark matter halo is 400 times smaller than what we would expect for such a dwarf galaxy.Led by Pieter van Dokkum (Yale University), the team that made this discovery has now followed up with detailed Hubble Space Telescope imaging and Keck spectroscopy. Their goal? To explore the objects that allowed them to make the dynamical-mass measurement: the oddly bright globular clusters of NGC 1052DF2.Sizes (circularized half-light radii) vs. absolute magnitudes for globular clusters in NGC1052DF2 (black) and the Milky Way (red). [Adapted from van Dokkum et al. 2018]Whats Up with the Globular Clusters?Van Dokkum and collaborators spectroscopically confirmed 11 compact objects associated with the faint galaxy. These objects are globular-cluster-like in their appearance, but the peak of their luminosity distribution is offset by a factor of four from globular clusters of other galaxies; these globular clusters are significantly brighter than is typical.Using the Hubble imaging, the authors determined that NGC 1052DF2s globular clusters are more than twice the size of the Milky Ways globular clusters in the same luminosity range. As is typical for globular clusters, they are an old ( 9.3 billion years) population and metal-poor.Rethinking Formation TheoriesThe long-standing picture of galaxies has closely connected old, metal-poor globular clusters to the galaxies dark-matter halos. Past studies have found that the ratio between the total globular-cluster mass and the overall mass of a galaxy (i.e., all dark + baryonic matter) holds remarkably constant across galaxies its typically 3 x 10-5. This has led researchers to believe that properties of the dark-matter halo may determine globular-cluster formation.The luminosity function of the compact objects in NGC 1052DF2. The red and blue curves show the luminosity functions of globular clusters in the Milky Way and in the typical ultra-diffuse galaxies of the Coma cluster, respectively. NGC 1052DF2s globular clusters peak at a significantly higher luminosity. [Adapted from van Dokkum et al. 2018]NGC 1052DF2, with a globular-cluster mass thats 3% of the mass of the galaxy ( 1000 times the expected ratio!), defies this picture. This unusual galaxy therefore demonstrates that the usual relation between globular-cluster mass and total galaxy mass probably isnt due to a fundamental connection between the dark-matter halo and globular-cluster formation. Instead, van Dokkum and collaborators suggest, globular-cluster formation may ultimately be a baryon-driven process.As with all unexpected discoveries in astronomy, we must now determine whether NGC 1052DF2 is simply a fluke, or whether it represents a new class of object we can expect to find more of. Either way, this unusual galaxy is forcing us to rethink what we know about galaxies and the star clusters they host.CitationPieter van Dokkum et al 2018 ApJL 856 L30. doi:10.3847/2041-8213/aab60b

    Full Text Available Commercial Hindi cinema plays a central role in the negotiation of national identity. For decades, the expatriate Indian served as a counter-example for acceptable behaviour, a living testimony of inappropriateness. In the mid-1990s, following the liberalization of the Indian economy, the rise of Hindu nationalism and the advent of a multiplex-going urban middle-class, the stereotype was turned around. The Non Resident Indian (NRI became the epitome of Indianness and embodied at once capitalist and consumerist modernity and patriarchal, Northern and Hindu traditionalism. This change was meant to cater to a lucrative niche market and reflected an uneasy transition period. In addition, the on screen NRI role models were seen as an instrument of Western modernity in India and of India's recognition as an international power in the West.

    Adaption of a single protein to perform multiple independent functions facilitates functional plasticity of the proteome allowing a limited number of protein-coding genes to perform a multitude of cellular processes. Multifunctionality is achievable by post-translational modifications and by modulating subcellular localization. Matrix metalloproteinases (MMPs), classically viewed as degraders of the extracellular matrix (ECM) responsible for matrix protein turnover, are more recently recognized as regulators of a range of extracellular bioactive molecules including chemokines, cytokines, and their binders. However, growing evidence has convincingly identified select MMPs in intracellular compartments with unexpected physiological and pathological roles. Intracellular MMPs have both proteolytic and non-proteolytic functions, including signal transduction and transcription factor activity thereby challenging their traditional designation as extracellular proteases. This review highlights current knowledge of subcellular location and activity of these "moonlighting" MMPs. Intracellular roles herald a new era of MMP research, rejuvenating interest in targeting these proteases in therapeutic strategies.

    Progress made in the last two decades in chemical vapour deposition technology has enabled the production of inexpensive, high-quality coatings made from diamond to become a scientific and commercial reality. Two properties of diamond make it a highly desirable candidate material for biomedical applications: first, it is bioinert, meaning that there is minimal immune response when diamond is implanted into the body, and second, its electrical conductivity can be altered in a controlled manner, from insulating to near-metallic. In vitro, diamond can be used as a substrate upon which a range of biological cells can be cultured. In vivo , diamond thin films have been proposed as coatings for implants and prostheses. Here, we review a large body of data regarding the use of diamond substrates for in vitro cell culture. We also detail more recent work exploring diamond-coated implants with the main targets being bone and neural tissue. We conclude that diamond emerges as one of the major new biomaterials of the twenty-first century that could shape the way medical treatment will be performed, especially when invasive procedures are required. © 2017 The Authors.

    Phototherapy can be used in two completely different but complementary therapeutic applications. While low level laser (or light) therapy (LLLT) uses red or near-infrared light alone to reduce inflammation, pain and stimulate tissue repair and regeneration, photodynamic therapy (PDT) uses the combination of light plus non-toxic dyes (called photosensitizers) to produce reactive oxygen species that can kill infectious microorganisms and cancer cells or destroy unwanted tissue (neo-vascularization in the choroid, atherosclerotic plaques in the arteries). The recent development of nanotechnology applied to medicine (nanomedicine) has opened a new front of advancement in the field of phototherapy and has provided hope for the development of nanoscale drug delivery platforms for effective killing of pathological cells and to promote repair and regeneration. Despite the well-known beneficial effects of phototherapy and nanomaterials in producing the killing of unwanted cells and promoting repair and regeneration, there are few reports that combine all three elements i.e. phototherapy, nanotechnology and, tissue repair and regeneration. However, these areas in all possible binary combinations have been addressed by many workers. The present review aims at highlighting the combined multi-model applications of phototherapy, nanotechnology and, reparative and regeneration medicine and outlines current strategies, future applications and limitations of nanoscale-assisted phototherapy for the management of cancers, microbial infections and other diseases, and to promote tissue repair and regeneration.

    Full Text Available Photobiomodulation (PBM describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying. One of the organ systems of the human body that is most necessary to life, and whose optimum functioning is most worried about by humankind in general, is the brain. The brain suffers from many different disorders that can be classified into three broad groupings: traumatic events (stroke, traumatic brain injury, and global ischemia, degenerative diseases (dementia, Alzheimer's and Parkinson's, and psychiatric disorders (depression, anxiety, post traumatic stress disorder. There is some evidence that all these seemingly diverse conditions can be beneficially affected by applying light to the head. There is even the possibility that PBM could be used for cognitive enhancement in normal healthy people. In this transcranial PBM (tPBM application, near-infrared (NIR light is often applied to the forehead because of the better penetration (no hair, longer wavelength. Some workers have used lasers, but recently the introduction of inexpensive light emitting diode (LED arrays has allowed the development of light emitting helmets or “brain caps”. This review will cover the mechanisms of action of photobiomodulation to the brain, and summarize some of the key pre-clinical studies and clinical trials that have been undertaken for diverse brain disorders.

    The increasing use of telecare will profoundly change nursing care. How to understand these changes is, however, far from clear. This is because (i) studies on telecare seldom consider the situation it replaces, and (ii) current concepts and methods used to study the impact of telecare may not allow us to fully grasp these changes. We suggest that an analysis of the changing materiality of care practices is a suitable way to articulate and reflect on possible concerns. It allows us to compare care practices in the same terms before and after telecare has been introduced. To demonstrate this, we study the materiality of the classical care setting, the nursing house call, to map the situation before telecare is introduced. Building on science and technology studies, we apply four categories as heuristics to analyse materiality in care: signs, dis/enablers (or scripted things), tools and practical arrangements. We leave open the question of how material arrangements could or should be matters of concern in nursing care, and instead argue for studies that give insights into the everyday tinkering with the materiality of care that both nurses and patients need to engage in. © 2015 Foundation for the Sociology of Health & Illness.

  10. Protein folding and misfolding shining light by infrared spectroscopy

    CERN Document Server

    Fabian, Heinz

    2012-01-01

    Infrared spectroscopy is a new and innovative technology to study protein folding/misfolding events in the broad arsenal of techniques conventionally used in this field. The progress in understanding protein folding and misfolding is primarily due to the development of biophysical methods which permit to probe conformational changes with high kinetic and structural resolution. The most commonly used approaches rely on rapid mixing methods to initiate the folding event via a sudden change in solvent conditions. Traditionally, techniques such as fluorescence, circular dichroism or visible absorption are applied to probe the process. In contrast to these techniques, infrared spectroscopy came into play only very recently, and the progress made in this field up to date which now permits to probe folding events over the time scale from picoseconds to minutes has not yet been discussed in a book. The aim of this book is to provide an overview of the developments as seen by some of the main contributors to the field...

    2013-01-01

    Advances in bioanalytical techniques have become crucial for both basic research and medical practice. One example, bioluminescence imaging (BLI), is based on the application of natural reactants with light-emitting capabilities (photoproteins and luciferases) isolated from a widespread group of organisms. The main challenges in cardiac regeneration remain unresolved, but a vast number of studies have harnessed BLI with the discovery of aequorin and green fluorescent proteins. First described in the luminous hydromedusan Aequorea victoria in the early 1960s, bioluminescent proteins have greatly contributed to the design and initiation of ongoing cell-based clinical trials on cardiovascular diseases. In conjunction with advances in reporter gene technology, BLI provides valuable information about the location and functional status of regenerative cells implanted into numerous animal models of disease. The purpose of this review was to present the great potential of BLI, among other existing imaging modalities, to refine effectiveness and underlying mechanisms of cardiac cell therapy. We recount the first discovery of natural primary compounds with light-emitting capabilities, and follow their applications to bioanalysis. We also illustrate insights and perspectives on BLI to illuminate current efforts in cardiac regeneration, where the future is bright. PMID:23402217

  15. Flavor alignment via shining in Randall-Sundrum models

    International Nuclear Information System (INIS)

    2010-01-01

    We present a class of warped extra dimensional models whose flavor violating interactions are much suppressed compared to the usual anarchic case due to flavor alignment. Such suppression can be achieved in models where part of the global flavor symmetry is gauged in the bulk and broken in a controlled manner. We show that the bulk masses can be aligned with the down-type Yukawa couplings by an appropriate choice of bulk flavon field representations and TeV brane dynamics. This alignment could reduce the flavor violating effects to levels that allow for a Kaluza-Klein scale as low as 2-3 TeV, making the model observable at the LHC. However, the up-type Yukawa couplings on the IR brane, which are bounded from below by recent bounds on CP violation in the D system, induce flavor misalignment radiatively. Off-diagonal down-type Yukawa couplings and kinetic mixings for the down quarks are both consequences of this effect. These radiative Yukawa corrections can be reduced by raising the flavon vacuum expectation value on the IR brane (at the price of some moderate tuning), or by extending the Higgs sector. The flavor changing effects from the radiatively induced Yukawa mixing terms are at around the current upper experimental bounds. We also show the generic bounds on UV-brane induced flavor violating effects, and comment on possible additional flavor violations from bulk flavor gauge bosons and the bulk Yukawa scalars.

    The Business Council of Australia's study on Prospects for Improved Energy Efficiency and the Application of Renewable Energy Resources is summarised. The study estimates that replacement of all off-peak electric units in Australia with solar gas boosted systems would reduce electricity consumption for residential water heating by approximately 25% and almost halve carbon dioxide emissions resulting from residential water heating. Furthermore, substitution of all water heating units in Australia with solar gas systems would reduce total emissions by about 80%. The study concludes that while substitution on such a scale could not readily be achieved even within several decades, the estimates do indicate the significant benefits that might be realised by a long term program. 2 refs., 3 tabs

    Renewable energy projects are increasingly confronted by local opposition, which delays and sometimes even prevents their implementation. This reflects the frequent gap between support for the general idea of renewables as a strategy for reducing carbon emissions, and acceptance of renewable energy...... installations in the local landscape. A number of countries have introduced financial incentives to promote community acceptance. The tool box of incentives is still limited but in recent years it has been expanded to address local concerns. Certain general characteristics can be identified, suggesting...... that there are at least three distinct categories of incentives: individual compensation, community benefits and ownership measures. Local opposition must be approached with caution, as financial incentives to promote local acceptance can be seen as buying consent or even ‘bribery’, stirring up further opposition....

    The article discusses the identification of efficiencies that can minimise transaction costs in energy trading and marketing. The article describes what is meant by 'trade management'. It is argued that a trade management system should be able to dovetail with existing or future ERP, advanced risk management, and financial management systems, to provide total enterprise integration. With the right trade management systems, traders have all the necessary information to help them manage exposure to financial risks in a world where energy trading companies are forced to accept very small margins. A trade management system can cover many aspects of a business including the winning of contracts for transportation deals, including rail, car, truck, barge and pipeline. There appears to be unprecedented opportunities for companies specialising in development and provision of trade management systems.

    1978-01-01

    2 1/2 years ago a consultation group was formed to help the Section for Social Questions of the Council of Churches in the Netherlands, to answer questions in the area of nuclear energy. During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches. Technical and economic information and the most important social questions are discussed. (C.F.)

    The measurement of primary interaction cross sections and the incorporation of these data into Monte Carlo calculations provide detailed information about the initial spatial distribution of absorbed dose. Our theoretical energy transport studies have focused on the use of this information to predict the evolution of chemical species formed as a result of the energy deposition. This effort has led to a stochastic approach to diffusion kinetics that can account for the influence of track structure on the yield of free radicals in the radiolysis of water. Fluorescence studies with pulsed alpha particle and proton beams provided the first experimental test of our stochastic model of tract structure effects. Our experimental studies use time-resolved emission spectroscopy to investigate the mechanism of energy transport in nonpolar liquids. Studies of the concentration dependence of time-resolved emission from solutions of benzene in cyclohexane also show the importance of using low benzene concentrations to minimize the influence of benzene dimers on the emission kinetics

    A combined power station is described, which enables one to convert solar energy and wind energy into other forms of energy. The plant consists of a water-filled boiler, in which solar energy heats the water by concentration, solar cells, and finally wind rotors, which transform wind energy into electrical energy. The transformed energy is partly available as steam heat, partly as mechanical or electrical energy. The plant can be used for supplying heating systems or electrolysis equipment. Finally, by incorporating suitable motors, a mobile version of the system can be produced.
