    Nursing by Buddhist during Meiji Japan was stimulated by the visiting nursing program conducted by nurses connected with the Kyoto Training School for Nurses. Why were Buddhist priests attracted to the visiting nursing. what did they try to adopt and what kind of nursing activities did they try to organize? As the first step to answer these questions. in this paper I considered the specialty. the sociality. and the nursing spirit of the home nursing and district nursing provided by the ...

    We have measured environmental radiation dose rates in several Prefectures, such as Ai chi Prefecture, Gifu Prefecture, and Mie Prefecture, in central Japan. Recently, we measured the environmental radiation dose rates in Kyoto and Shiga Prefectures that are also located in central Japan with a car-borne survey system. At the time of measurement, Kyoto Prefecture (area: 4,613 km 2 ) had a total of 36 districts, and Shiga Prefecture (area: 3,387 km 2 ) a total of 26. Terrestrial gamma ray dose rates and secondary cosmic ray dose rates were measured by a 2 inches ψ x 2 inches NaI(Tl) scintillation counter and a handy-type altimeter (GPS eTrex Legend by Gamin), respectively. The following factors were taken into consideration the shielding effect of the car body, the effect of the road pavement, radon progeny borne by precipitation, and increases in tunnels and near the walls. Terrestrial gamma ray dose rates in Kyoto and Shiga Prefectures were estimated to be 51.7 ± 6.0 n Gy/h (district average: 52.4 ± 4.7 n Gy/h), 52.2 ± 10.5 n Gy/h (district average: 51.9 ± 8.1 n Gy/h), respectively. Secondary cosmic ray dose rates in Kyoto and Shiga Prefectures were 30.0 ± 0.6 n Gy/h (district average: 29.9 ±0.3 n Gy/h), 30.1 ± 0.3 n Gy/h (district average: 30.0 ± 0.2 n Gy/h), respectively. The environmental radiation dose rates due to the sum dose rates of terrestrial gamma ray and secondary cosmic ray in Kyoto and Shiga Prefectures were 81.7 ± 6.2 n Gy/h (district average: 82.3 ± 4.8 n Gy/h), 82.3 ± 10.6 n Gy/h (district average: 82.0 ± 8.1 n Gy/h), respectively. We confirmed that the environmental radiation dose rates in Kyoto and Shiga Prefectures mainly depended on the change of the terrestrial gamma ray dose rates, since the secondary cosmic ray dose rates had little change. Therefore, radiation dose-rate maps of the terrestrial gamma rays as well as maps of the environmental radiation dose-rate were drawn. (author)

    Global warming and the associated changes in the world climate pattern have been accepted world wide as the gravest threat to humanity in the 20th century. To mitigate the impacts of global warming, the Kyoto Protocol was established in 1997 with the objective of reducing global greenhouse gases (GHGs) emission, in particular carbon dioxide (CO 2 ), by 5.2% below 1990 levels. Developed nations that ratified the Protocol are committed to GHG reduction targets while developing nations are encouraged to reduce GHG emissions on a voluntary basis. Since most of the GHGs emissions come from the energy sector, energy policy plays an important role in fulfilling the Kyoto Protocol obligations. This year marks the beginning of the commitment period for the 2012 Kyoto Protocol. In this case, it would be worthwhile to compare the energy policies in Malaysia and Japan as these nations move towards fulfilling their obligations towards the Kyoto Protocol; bearing in mind that both countries ratified the Protocol, but that Japan commits a reduction target of 6% while Malaysia bears no obligation. Based on the comparison, recommendations were made on how a developing nation like Malaysia could adopt the policies implemented in Japan to suit local conditions and contribute significantly to GHG reduction.

    When I addressed the 2011 STS Forum a year ago, Japan was still dealing with the immediate aftermath of the Fukushima Daiichi accident. Now, we are well into the post-accident phase. The emphasis for the IAEA and its 155 Member States is on implementing the IAEA Action Plan on Nuclear Safety, which was adopted just over a year ago. Progress has been made in many areas. Possible safety weak points at nuclear power plants have been identified and are being addressed. These include issues such as ensuring adequate backup electrical power in case of a blackout. The IAEA has expanded its programme of expert peer reviews. We undertook a systematic review of IAEA Safety Standards, taking into account lessons learned from the Fukushima Daiichi accident. And we held a series of international expert meetings focussing on different technical issues. A lot has been done already, but a considerable amount of work still remains to be done under the IAEA Action Plan on Nuclear Safety. It is essential that all of us - Member States, the IAEA and other key stakeholders - maintain our sense of urgency and our commitment to implementing the Action Plan in full. In December, the Fukushima Ministerial Conference on Nuclear Safety, organized by the Government of Japan and the IAEA, will take place in Fukushima Prefecture. This Conference will be a good opportunity for participants from abroad to learn first-hand lessons from the accident. For Japan, it will be an excellent opportunity to understand how other countries are reacting to the accident. For the IAEA, it will be an occasion to redouble our efforts to help people in Fukushima. A year ago, I told the STS Forum that nuclear power looked set to remain an important option for many countries, despite the Fukushima Daiichi accident. This trend has become even clearer during the past year. The latest IAEA projection is for global nuclear power capacity to grow by nearly 25 percent from current levels to 456 gigawatts by 2030. That is

    We studied a 107 Ma vogesite (a kind of lamprophyre with alkali-feldspar > plagioclase, and hornblende ± clinopyroxene ± biotite) dike in the Kinki district of the Tamba Belt, Kyoto Prefecture, SW Japan, using petrography, mineralogy, K-Ar ages, and geochemistry to evaluate its petrogenesis and tectonic implications. The dike has the very specific geochemical characteristics of a primitive high-Mg basalt, with 48-50 wt.% SiO2 (anhydrous basis), high values of Mg# (67.3-72.4), and high Cr ( 431 ppm), Ni ( 371 ppm), and Co ( 52 ppm) contents. The vogesite is alkaline and ne-normative with high concentrations of large ion lithophile elements (LILEs: Sr = 1270-2200 ppm, Ba = 3910-26,900 ppm), light rare earth elements (LREEs) [(La/Yb)n = 58-62), and high field strength elements (HFSEs: TiO2 = 1.5-1.8 wt.%, Nb = 24-33 ppm, Zr = 171-251 ppm), and the vogesite can be classified as a high-Nb basalt (HNB). The vogesite was formed by the lowest degree of melting of metasomatized mantle in the garnet stability field, and it may also have been formed at higher melting pressures than other Kyoto lamprophyres. The low degree of melting is the primary reason for the high-Nb content of the vogesite, not mantle metasomatism, and a higher degree of melting would have changed the primary magma composition from a HNB to a Nb-enriched basalt (NEB). The vogesite magma was contaminated at an early stage of its development by melts derived from sediments drawn down a subduction zone, as indicated by some geochemical indices and the initial Nd isotope ratios. The vogesite exhibits positive correlations between εSr(107 Ma) values (5.4-50.9) and its high Ba and Sr concentrations, and it has a limited range of εNd(107 Ma) values (+ 0.97 to + 2.4). The fact that the vogesite contains centimeter-sized xenoliths of chert, which are composed of polycrystalline quartz, calcite, barite, pyrite, and magnetite, indicates that the barium contamination took place during the ascent of the

    Full text: Distinguished Guests, Ladies and Gentlemen, It is my honour to address participants at this opening session of the International Conference on Fast Reactors and Related Fuel Cycles: Challenges and Opportunities, organized by the IAEA and hosted by the Japan Atomic Energy Agency. Fast reactor technology has the potential to ensure that energy resources which would last hundreds of years with the technology we are using today will actually last several thousand years. In other words it can withstand enormous increases in demand. This innovative technology also reduces the risk to the environment and helps to limit the burden that will be placed on future generations in the form of waste products. The coming year will be an exciting one for the development of fast-spectrum nuclear reactors. We expect to reach many important milestones: - the first criticality of the China Experimental Fast Reactor; - the restart of the Monju prototype fast reactor in Japan; and - the new insights we will gain through the end-of-life studies at the Phenix reactor in France. In the near future, new fast reactors will be commissioned: the 500MW(e) Prototype Fast Breeder Reactor in India, the first in a series of five of the same type, and the BN-800 reactor in the Russian Federation. Moreover, France, Japan, India, China and the Republic of Korea are preparing advanced prototypes, demonstration or commercial reactors for the 2020-2030 period. Nuclear power is set to be an increasingly important part of the global energy mix in the coming decades as demand for energy grows. Scores of countries in both the developed and developing world have told the IAEA that they are interested in introducing nuclear power. The 30 countries which already have nuclear power reactors are set to build more. This trend is likely to be accompanied by accelerated deployment of fast reactors. Continued advances in research and technology development are necessary to ensure improved economics and

  13. External impacts on traditional commons and present-day changes: a case study of iriai forests in Yamaguni district, Kyoto, Japan

    Full Text Available Japanese iriai forests have been regarded as a model of institutions for collective action in the sustainable use of resources in studies on commons, as pointed out by Ostrom (1990 and McKean (1996. However, present-day iriai forests that have survived decades of legal and even greater economic and social challenges have undergone significant alteration. While we know that external conditions such as foreign competition from low-cost timber have depressed the Japanese forestry industry and thus reduced the health of Japanese forests as a whole, we do not know about the current state of the iriai forests in particular. Adaptation to external impacts is crucial for the survival of the commons in a modern industrialized society. This study examines external impacts on traditional commons and the resultant institutional changes in current Japan. We cannot easily track the changes in traditional commons without deep understanding of many cases, because the factors affecting their functioning are complex and diverse. Therefore, we opted to use the case study method to improve the empirical foundations for analyzing these complex phenomena. Our goal was to examine the institutional changes resulting from one source of pressure found in many commons near urbanizing areas in postwar Japan – an increase in newcomers – as well as from the pressure of foreign competition in forest products. We chose eleven villages in the Yamaguni district in Kyoto city that manage their own common forests and studied the documented rules in these communities. We used participant observation and also conducted interviews with villagers to obtain their sense of change over time, the impact of globalization, and the current status of the commons. This paper derived the following conclusions. First, the village community can adapt its institutions to external influences by supporting continuous institutional change. Second, although village communities can overcome most

    Full Text Available Kyoto has been the capital of Japan from 794 until when the capital has moved in 1868 to Tokyo with the end of Tokugawa Shoguns and the beginning of the Meiji Restoration. The loss of the seat of government was a shock to citizens of Kyoto as the city had been the Imperial and Cultural center of the nation for over 1.000 years. The combination of the court and the great temples had enlivened and enriched the life of the city. At the beginning of the founding of the capital, in the Heian period (794-1185 to east of Kyoto, was built a noble and religious place. This area is Okazaki. Here the Emperor Kammu (736-805 had created the city of Heian-kyo (Kyoto in 794. This area was full of Temples and Shrines. Only in the Edo period (1603-1867 Okazaki area assumed the role of suburban agricultural zone which provided the food production to the urban habitants. But after the Meiji Restoration (1868-1912, the role of Okazaki area changes completely. In 1885, Kyoto prefecture started the great public canalization project as the water supply between Kyoto and Otsu of Shiga prefecture. Kyoto prefecture also planed the industrial district construction in Okazaki area. From the late nineteenth century Okazaki area became a symbol of the modernization of Kyoto city. This contribution intends to analyze the urban landscape composed of the different styles of architecture especially constructed after the Meiji period (1868-1912. Tangible and intangible signs remained as modern gardens, significant museums and cultural institutions among the ancient temples provide opportunities to reflect on the important role of suburban area of the historic city. These studies are supported by archival documents and by current measures and policies for landscape conservation by Kyoto Municipality.

    Summary Background The incidence of femoral neck and trochanteric fractures reportedly differ by age and regionality. We investigated differences in monthly variations of the occurrence of femoral neck and trochanteric fractures as well as place and cause of injury in the Kyoto prefecture over a 6-year period. Methods Fracture type (neck or trochanteric fracture), age, sex, place of injury, and cause of injury were surveyed among patients aged ≥ 65 years with hip fractures that occurred between 2008 and 2013 who were treated in 1 of 13 participating hospitals (5 in an urban area and 8 in a rural area). The proportion of sick beds in the participating hospitals was 24.7% (4,151/16,781). Monthly variations in the number of patients were investigated in urban and rural areas in addition to the entire Kyoto prefecture. Place of injury was classified as indoors or outdoors, and cause of injury was categorized as simple fall, accident, or uncertain. Results There were 2,826 patients with neck fractures (mean age, 82.1 years) and 3,305 patients with trochanteric fractures (mean age, 85.0 years). There were similarities in the monthly variation of the number of fractures in addition to the place and cause of injury between neck and trochanteric fractures. Indoors (approximately 74%) and simple falls (approximately 78%) were the primary place and cause of injury, respectively. The place of injury was not significantly different by fracture type with each age group. Significantly more patients with neck fracture had “uncertain” as the cause of injury than trochanteric fracture in all age groups. Conclusions Based on the results of the present study, the injury pattern might not have a great effect on the susceptibility difference between neck and trochanteric fractures. PMID:27252738

    Facing the global problems raised by the climatic change, it is absolutely necessary to bring forth worldwide orientations which must balance the economic growth in the developing countries, the competition between countries and between industrial companies, the right repartition of the efforts of developed countries and the remaining world's countries as well as among the developed countries. This EDF press communique, concerning the 3. Conference of the Parties of the UN Framework - Convention, held in Kyoto on 1-10 Dec 1999, presents the results of EDF struggle against the Greenhouse effect, a comparative statistics of the CO 2 emission and, particularly, the role of electric sector. The following conclusions are drown in this report: 1. No matter what common target will be established for CO 2 emission (2-4.5 tones per inhabitant, for instance), it implies that big countries like US and Canada should decide on plans for significant lowering of the emissions while Europe as well as China have still important steps to do; 2. Although, Europe has mastered rather well the global CO 2 emission there are still very contrasting values from the different countries of the European Union; 3. The emissions produced by transport do increase continuously and will soon become the main contributor to the polluting emissions; 4. The European industrial sector has reduced its emission by about 12% during the last ten years and at present it is only the fourth contributor; 5. The electric sector can bring a major contribution to the pollution abatement by choosing CO 2 non-emitting power generating systems, so as the plots giving the emission evolution in France, Sweden or Austria demonstrate

    In the Kyoto Protocol to the FCCC three different forms of GHG emission reduction titles through market-based international cooperation are defined: emission reduction units under Article 6; certified emission reductions in the framework of the Clean Development Mechanism (CDM) under Article 12; and emissions trading under Article 17. Although defined under different Articles in the Protocol, it seems reasonable to assume that the three mechanisms will not operate separately. After CoP3 the author registered several comments, opinions and concerns related to the flexibility provisions under the Kyoto Protocol

  6. Climate policy after Kyoto

    International Nuclear Information System (INIS)

    Gerholm, T.R.

    2002-01-01

    The Kyoto Convention recommends reductions in emissions of CO 2 and other greenhouse gases, to mitigate the rate of climate change. Lively debate has taken place in many countries, not least over the political and economic implications. The basis for the Kyoto discussions was a set of studies commissioned, compiled and published by the UN's International Panel on Climate Change (IPCC). At first glance this scientific foundation plainly shows that significant climate change will occur unless emissions of greenhouse gases are sharply curtailed. On closer examination, the scientific evidence provided in the IPCC material is far from clear. Reputable scientists have expressed critical views about the interpretation of the scientific results and, even more, of the way the material is being used for policy purposes. The main purpose of this book is to voice this critique. To give the reader some context, a central section from the IPCC's basic document is presented first. There follow nine papers, by prominent natural and social scientists, in which the reasons for their sceptical attitudes are developed. A final paper by Professor Bert Bolin, chairman of the IPCC during the time when most of the material was produced, provides a response and commentary to the critique. The aim of the editor and authors, in presenting the material in this way, rather than as a polemical tract, is to leave open to the reader the question: Is global warming a consequence of man's activities, or are there other reasons; if so, is adopting policies with significant economic consequences, a reasonable response?

    In 1997 Kyoto protocol was adopted at the third session of Conference of the parties of UNFCC in Kyoto, Japan. This protocol restricts the industrialized countries and those in transition to a market economy agreed to limit or reduce their emissions. In Pakistan the government is also taking steps to reduce the pollution. This paper discusses the possible low carbon emitting electricity generation options by keeping in view the current energy scenario of Pakistan and the new energy policy announced by the Government of Pakistan for renewable energy promotion.

    2018-04-16

    The Kyoto embryo collection was begun in 1961 by Dr. Hideo Nishimura. The collection has been continuously developed and currently contains over 44,000 human normal and abnormal specimens. Beginning online in 1997, the internet provided an opportunity to make embryos from the collection widely available for research and educational purposes (http://tiny.cc/Embryo). These embryonic development resources have been continuously published and available from that time until today. Published in Japanese as an Atlas of Embryonic Development. Published online as the Kyoto Human Embryo Visualization Project (http://atlas.cac.med.kyoto-u.ac.jp) and also as the Human Embryo Atlas (http://tiny.cc/Human_Embryo_Atlas). Published now electronically as a digital eBook (http://tiny.cc/Kyoto_Collection_eBook). This new digital format allows incorporation of whole embryo and histology manipulable images, labels, and a linked glossary. New imaging modalities of magnetic resonance imaging (MRI) and episcopic fluorescence image capture (EFIC) can also be easily displayed as animations. For research, the collection specimens and histological sections have been extensively studied and published in several hundred papers, discussed here and elsewhere in this special edition. I will also describe how the Kyoto collection will now form a major partner of a new international embryology research group, the Digital Embryology Consortium (https://human-embryology.org). The digital Kyoto collection will be made available for remote researcher access, analysis, and comparison with other collections allowing new research and educational applications.

    Kyoto protocol, put in force in Feb. 2005, is criticized from both sides, those demanding a stricter target for GHG (green house gas) emission reduction on the one side, and those claiming for more flexible and comprehensive controls of the emission on the other side, for its modest target and narrow coverage. Even though its value could be that of a mere precedent and experimentation, Kyoto protocol includes very special experimentation to assist the world wide cooperation for a mitigation of climate change, i.e. the introduction of three mechanisms, emissions trading, joint implementation, and clean development mechanism (CDM). Together, they are called Kyoto mechanisms. Evaluation of mechanisms is one important role of microeconomics and the game theory is a major tool for it. We shall scrutinize these mechanisms from such viewpoint. A special attention is placed on CDM, as it is the novel mechanism introduced by Kyoto protocol, and gives a unique link between Annex I nations (mostly developed countries) and non-Annex I nations (mostly developing countries). Next, we examine some of the currently proposed schemes after 2013, the post Kyoto schemes. One of the chief issues is the possibility of making a comprehensive agreement including both the USA and large developing countries with rapidly increasing emission levels of GHG like China and India. Adding to these, not only the proposed schemes themselves, but the process of negotiation itself inspired several researches in cooperative game theory and in particular, coalition formation theory. We shall touch upon this issue separately, and examine how successfully they predicted the outcome leading to Kyoto, retrospectively. Finally, we end our discussion with a brief consideration over the underlining normative argument concerning these schemes.

    The Japanese nuclear power programme began with reactors imported from the United States. A natural uranium heavy water reactor using domestic materials was started in 1958. Subsequent progress was with light water reactors imported from the United States. Domestic reactor development was of a fast breeder reactor and an advanced thermal reactor. By March 1986 there were 32 commercial power plants in operation which produced approximately 23% of the electricity consumed in Japan. Ten more are under construction and six more are planned. Their location and comparative generating cost are tabulated. Energy demand and targets for nuclear power generation are discussed. The FBR advanced thermal reactor and high temperature reactor programmes are summarized. The Japanese nuclear fuel cycle - uranium prospecting, enrichment, reprocessing, the development of mixed oxide fuels, thermal recycling and radioactive waste management is also discussed. (U.K.)

    The Kyoto city, which is located in the northern part of Kyoto basin in Japan, has a long history of >1,200 years since the city was initially constructed. The city has been a populated area with many buildings and the center of the politics, economy and culture in Japan for nearly 1,000 years. Some of these buildings are now subscribed as the world's cultural heritage. The Kyoto city has experienced six damaging large earthquakes during the historical period: i.e., in 976, 1185, 1449, 1596, 1662, and 1830. Among these, the last three earthquakes which caused severe damage in Kyoto occurred during the period in which the urban area had expanded. These earthquakes are considered to be inland earthquakes which occurred around the Kyoto basin. The damage distribution in Kyoto from historical large earthquakes is strongly controlled by ground condition and earthquakes resistance of buildings rather than distance from estimated source fault. Therefore, it is necessary to consider not only the strength of ground shaking but also the condition of building such as elapsed years since the construction or last repair in order to more accurately and reliably estimate seismic intensity distribution from historical earthquakes in Kyoto. The obtained seismic intensity map would be helpful for reducing and mitigating disaster from future large earthquakes.

    Facing the global problems raised by the climatic change, it is absolutely necessary to bring forth worldwide orientations which must balance the economic growth in the developing countries, the competition between countries and between industrial companies, the right repartition of the efforts of developed countries and the remaining world's countries as well as among the developed countries. This EDF press communique, concerning the 3. Conference of the Parties of the UN Framework - Convention, held in Kyoto on 1-10 Dec 1999, presents the results of EDF struggle against the Greenhouse effect, a comparative statistics of the CO{sub 2} emission and, particularly, the role of electric sector. The following conclusions are drown in this report: 1. No matter what common target will be established for CO{sub 2} emission (2-4.5 tones per inhabitant, for instance), it implies that big countries like US and Canada should decide on plans for significant lowering of the emissions while Europe as well as China have still important steps to do; 2. Although, Europe has mastered rather well the global CO{sub 2} emission there are still very contrasting values from the different countries of the European Union; 3. The emissions produced by transport do increase continuously and will soon become the main contributor to the polluting emissions; 4. The European industrial sector has reduced its emission by about 12% during the last ten years and at present it is only the fourth contributor; 5. The electric sector can bring a major contribution to the pollution abatement by choosing CO{sub 2} non-emitting power generating systems, so as the plots giving the emission evolution in France, Sweden or Austria demonstrate.

    2003-01-01

    The author provided a historical perspective of energy use and the role of carbon in the western hemisphere by displaying a series of graphs showing carbon intensity of energy, carbon emissions from energy, and the long path to green power. The 1990s represented a decade of progress. Almost three times as much wind capacity as nuclear capacity was added worldwide in 2001. The main challenge for the 21st century will be to bring under-developed countries into the fold while perpetuating the economic and human progress of the twentieth century. It was emphasized that environmental damage caused by utilities must be reversed. The contemporary context for the Kyoto Protocol was reviewed. Canada's commitment under the Kyoto Protocol is to reduce greenhouse gas emissions by 6 per cent below 1990 levels. The challenge for utility regulators to meet this commitment was examined. The costs are not entirely excessive. Some of the regulatory issues were discussed, namely revising a broad rate making framework, cost recovery and others. The Kyoto compliance plan was also reviewed with reference to internal options, external options, identification of regulatory barriers, and consideration of greenhouse gas credit markets. figs

    Globalization of the economy will probably coincide with more transport, as a result of which the environmental burden will increase. Thus, the Kyoto standards will be difficult to realize. Based on four economic scenarios with different levels of globalization insight is gained into the possible consequences of future developments (economic development, investment, consumption, (regional) specializations, and trade up to 2020) in the transportation sector, focusing on the Netherlands. Those developments have been made concrete by means of the Worldscan model, developed by the Netherlands Bureau for Economic Policy Analysis (CPB). 8 refs.

  1. Hydro in the Kyoto era

    International Nuclear Information System (INIS)

    Bourdon, M.-C.

    2003-01-01

    Quebec has the best performance in North America in terms of greenhouse gas (GHG) emissions. Unlike neighbouring provinces and states which rely heavily on coal for power generation, Quebec generates 96 per cent of its electricity from hydroelectric power. However, no new dams have been built in the past decade in Quebec due to land disputes with Aboriginal communities and general distrust among many ecologists. It takes about 12 years for a hydroelectric project to come to fruition. For that reason, and in order to capitalize on energy market opportunities, Hydro-Quebec is seriously considering expanding its generating capability beyond the needs of Quebec consumers, with gas-fired thermal generating stations. Environmental groups claim that the proposal to build the Suroit combined-cycle facility near the United States border destroys Quebec's efforts to honour the Kyoto Protocol. Economists argue that it is entirely in the spirit of Kyoto if exports of hydroelectricity or natural gas from Canada to the United States leads to less use of oil or coal. But one energy modeling expert at INRS-Energie et Materiaux claims that Quebec has a moral obligation to develop hydroelectricity for its own use as well as for export purposes, noting that any country with the good fortune to have renewable forms of energy, such as wind and hydro, should develop them to lower world GHG emissions. Quebec has many opportunities to sell hydroelectricity even while domestic demand grows. Hydroelectricity from Quebec should interest some states that have adopted their own GHG reduction standards, despite the U.S. government's refusal to ratify Kyoto. It should also interest Ontario and the Maritimes because they will be trying to reduce emissions from their thermal plants. The current situation does not favour the Kyoto Protocol. Exports of electricity from Quebec have dropped because no new dams have been built in recent years and gas-fired plants are looking more attractive to power

    The Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3) will be held in Kyoto in December 1997. Described herein are the current status and issues of the convention. USA and Japan, which hold important keys to set up the abatement target, have issued no proposals concretely at the current AGBM (Ad-hoc Group Berlin Mandate) 7, and the conference for the concrete targets will be decided in the next AGBM 8 to be held in October. The final target will be set by the ministerial segment of COP3, because the negotiations for the treaty are political in nature. USA proposes reduction at a uniform, realistic rate, and Japan proposes reduction at a uniform rate or setting up the emission target per capita, each being different from reduction at a much higher uniform rate proposed by EU. Within EU, however, 10% out of 15% reduction rate it proposes is agreed by the member countries, and the remaining rate of % may not be agreed. It is necessary for the advanced parties to set up realistic and legally binding solutions, including ratification by USA, which can persuade the developing countries. tab.1

    Red auroras were observed in Japan during an extreme magnetic storm that occurred on 17 September 1770. We show new evidence that the red aurora extended toward the zenith of Kyoto around midnight. The basic appearance of the historical painting of the red aurora is geometrically reproduced based on the inclination of the local magnetic field and a detailed description in a newly discovered diary. The presence of the inclined zenith aurora over Kyoto suggests that the intensity of the September 1770 magnetic storm is comparable to, or slightly larger than that of the September 1859 Carrington storm.

  10. Implementation of the Kyoto protocol

    International Nuclear Information System (INIS)

    2006-07-01

    The Rio Earth summit in 1992 has been the starting point of an international awareness about the global risk of climatic change. At this occasion, the richest countries committed themselves to stabilize their greenhouse gas emissions and to reach by the year 2000 an emissions level equivalent to the one of 1990. The Kyoto protocol in 1997 has permitted to convert this will into juridically constraining quantitative commitments. In 2005, Russia ratified the protocol while in 2001 the USA refused to do so. Because the commitments signed are ambitious, flexibility mechanisms have been implemented: 'emission permits' (emissions trading), 'joint implementation' allowing the investments abroad for greenhouse gases abatement in another developed country, and 'clean development mechanisms' when investments are made in a developing country. The Marrakech conference of December 2001 has permitted to fix up the eligibility criteria of projects belonging to the joint implementation and clean development mechanisms. The effective implementation of these mechanisms still raises technical difficulties to evaluate and measure the effective abatement of greenhouse gas emissions. (J.S.)

    2005-01-01

    Recently EURELECTRIC welcome the proposal of new EC Directive concerning the inclusion in the EU Emissions Trading Scheme (ETS) of credits from the project mechanisms - Joint Implementation (JI) and Clean Development Mechanism (CDM). The proposed Directive is an amendment to the EU Emissions Trading Directive adopted in June 2003. EURELECTRIC calls for unlimited use of credits in ETS. The draft Directive provides for the application of these mechanisms to begin as of 2008, on condition that the Kyoto Protocol does actually enter into force, an event which is still dependent on Russia's ratification. Such ratification has been subject to contradictory statements from the Russian Government, and the question of whether their signature to the Protocol is forthcoming is still fraught with uncertainty. Although it is not anticipated that significant quantities of JI or CDM certified credits will be available in the period 2005-2007, those that do become available would provide some additional liquidity in the emissions trading market. There is a direct relation between the coming ETS and electricity pricing: environmental policy is the driver, based on the need to switch to a low-carbon future and manage the necessary investments in a rational manner - and emissions trading is the best solution available. Romania has good opportunities to be involved in the greenhouse gases market, both in ETS and JI mechanisms. Some JI projects between Romanian and The Netherlands are already done or underway.

    Full Text Available An accelerator-driven system consists of a subcritical reactor and a controllable external neutron source. The reactor in an accelerator-driven system can sustain fission reactions in a subcritical state using an external neutron source, which is an intrinsic safety feature of the system. The system can provide efficient transmutations of nuclear wastes such as minor actinides and long-lived fission products and generate electricity. Recently at Kyoto University Research Reactor Institute (KURRI; Kyoto, Japan, a series of reactor physics experiments was conducted with the Kyoto University Critical Assembly and a Cockcroft–Walton type accelerator, which generates the external neutron source by deuterium–tritium reactions. In this paper, neutronic analyses of a series of experiments have been re-estimated by using the latest Monte Carlo code and nuclear data libraries. This feasibility study is presented through the comparison of Monte Carlo simulation results with measurements.

  15. Emission Trading and the Kyoto protocol: Are they efficient economic instruments?

    Ibanez Londono, Ana Maria

    1998-02-01

    The Kyoto Protocol establishes a tradeable permits market for green house gases -GHG- emissions to reduce the costs of meeting the Protocol obligations. Economic theory provides the arguments to support the creation of GHG tradeable permits. Several economic researches have shown that vis-a-vis command and control regulations, tradeable permits induce economic agents to achieve environmental goals at a minimum cost. However, the conditions to minimize costs through tradeable permits are stringent. Tradeable permits require well functioning markets, e.g. perfect competition and perfect information. The tradeable permits market created by the Kyoto Protocol hardly meet these necessary conditions. Some countries like Japan, Great Britain and the United Stated are large emitters and thus may exert market power. Price manipulation may have implications over the static and dynamic efficiency of the permits. This paper takes a first look to the consequences of imperfect markets on the tradeable permit system of the Kyoto Protocol

    It's July 1945. Germany is in defeat and the atomic bombs are on their way to Japan. Under the direction of Samuel Goudsmit, the Allies are holding some of the top German nuclear scientists-among them Heisenberg, Hahn, and Gerlach-captive in Farm Hall, an English country manor near Cambridge, England. As secret microphones record their conversations, the scientists are unaware of why they are being held or for how long. Thinking themselves far ahead of the Allies, how will they react to the news of the atomic bombs? How will these famous scientists explain to themselves and to the world their failure to achieve even a chain reaction? How will they come to terms with the horror of the Third Reich, their work for such a regime, and their behavior during that period? This one-act play is based upon the transcripts of their conversations as well as the author's historical work on the subject.

    Histological gastritis is associated with gastric cancer, but its diagnosis requires biopsy. Many classifications of endoscopic gastritis are available, but not all are useful for risk stratification of gastric cancer. The Kyoto Classification of Gastritis was proposed at the 85th Congress of the Japan Gastroenterological Endoscopy Society. This cross-sectional study evaluated the usefulness of the Kyoto Classification of Gastritis for risk stratification of gastric cancer. From August 2013 to September 2014, esophagogastroduodenoscopy was performed and the gastric findings evaluated according to the Kyoto Classification of Gastritis in a total of 4062 patients. The following five endoscopic findings were selected based on previous reports: atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness. A total of 3392 patients (1746 [51%] men and 1646 [49%] women) were analyzed. Among them, 107 gastric cancers were diagnosed. Atrophy was found in 2585 (78%) and intestinal metaplasia in 924 (27%). Enlarged folds, nodularity, and diffuse redness were found in 197 (5.8%), 22 (0.6%), and 573 (17%), respectively. In univariate analyses, the severity of atrophy, intestinal metaplasia, diffuse redness, age, and male sex were associated with gastric cancer. In a multivariate analysis, atrophy and male sex were found to be independent risk factors. Younger age and severe atrophy were determined to be associated with diffuse-type gastric cancer. Endoscopic detection of atrophy was associated with the risk of gastric cancer. Thus, patients with severe atrophy should be examined carefully and may require intensive follow-up. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Kyoto protocol is a foundation for achieving an ultimate goal of UNFCCC, which is to stabilizing greenhouse gas concentration in the air. The clean development system is a core element for successful implementation of Kyoto protocol with other Kyoto mechanisms. While UNFCCC requires a new paradigm changing to sustainable development considering demand and future environment from the past supply-oriented resource consumption, the clean development system will be used as a means of successful establishment of a new paradigm in 21st century. As environmental problem is integrated with economic problem and each country is thriving for securing its own economic benefit in the issue of environmental conservation, Korea should do its best to have both of global environmental conservation and economic benefit for its own. 1 tab.

  2. The Kyoto mechanisms and technological innovation

    Lund, Henrik

    2006-01-01

    Climate change response, including the implementation of the Kyoto targets as the first step, calls for technological innovation of future sustainable energy systems. Based on the Danish case, this paper evaluates the type of technological change necessary. During a period of 30 years, Denmark managed to stabilize primary energy supply, and CO 2 emissions decreased by 10%, during a period of 20 years. However, after the introduction of the Kyoto Mechanisms, Denmark has changed its strategy. Instead of continuing the domestic CO 2 emission controls, Denmark plans to buy CO 2 reductions in other countries. Consequently, the innovative technological development has changed. This paper evaluates the character of such change and makes preliminary recommendations for policies to encourage the use of the Kyoto Mechanisms as an acceleration of the necessary technological innovation.

    2005-01-01

    Croatia as an Annex I country of the UN Framework Convention on Climate Change and a country that has pledged in the Annex B of the Kyoto Protocol to reduce its GHG emissions by 5% will have to envisage a new energy strategy. Compared to the energy consumption collapse in some transitional countries, Croatia has passed through a relatively short-term reduction of GHG emissions since 1990 because of higher energy efficiency of its pretransition economy. It is expected that in case of baseline scenario, it will breach the Kyoto target in 2003. Several scenarios of power generation are compared from the point of view of GHG emissions. The cost-effective scenario expects a mixture of coal and gas fired power plants to be built to satisfy the new demand and to replace the old power plants that are being decommissioned. More Kyoto friendly scenario envisages forcing the compliance with the Protocol with measures only in power generation sector by the construction of mainly zero emission generating capacity in the future, while decommissioning the old plants as planned, and is compared to the others from the GHG emissions point of view. The conclusion is that by measures tackling only power generation, it will not be possible to keep GHG emission under the Kyoto target level. The case of including the emissions from Croatian owned power plants in former Yugoslavia is also discussed

    The commitment of the upstream oil and gas industry to implement actions to help Canadians become more efficient in their use of energy was discussed. The goals of the Rio Framework convention revolved around achieving greenhouse gas emissions reductions in the least costly manner. The industrial sector responded to that challenge through voluntary efforts to reduce greenhouse gases. However, from an industry perspective, the VCR (voluntary challenge registry) performance was inconsistent. While the upstream oil and gas industry participated aggressively, other industrial sectors, particularly the transportation sector, failed to participate. Progress was too slow and too late. The Third Conference of the Parties in Kyoto, resulted in a binding commitment of between 20 and 25 per cent per annum reduction for Canada. Emissions trading among developed countries is also included in the Kyoto Protocols. The speaker considered the reduction commitment of 20 to 25 per cent for Canada unrealistic, and suggested that the Kyoto protocol may be flawed, if only because so many of the details have not been spelled out. The importance of the roles of the federal and provincial governments in enforcing their consultative processes was emphasized. In the view of this speaker and that of the Canadian Association of Petroleum Producers, the biggest disappointments coming out of Kyoto, was the failure to gain meaningful involvement from the developing world. A global effort to reduce emissions cannot be achieved without the participation of the developing countries

    The Research Reactor Institute (RRI), Kyoto University, for aiming at performing the 'Experiments using a reactor and its related research', was established in Showa 38 (1963) as a cooperative research institute for universities and so on in allover Japan. Operation using KUR of one of main facilities in RRI was started by 1 MW of its rated output in 1964, and converted to 5 MW in 1968, after which through development , addition and modification of various research apparatus it has been proposed to the cooperative application researches with universities and so on in allover Japan, hitherto. Among these periods, its research organization is improved to six departments containing twenty divisions and two attached research facilities to progress some investigations on future plans at RRI for response to new researching trends. Here were described on present state of research on use of low concentrated uranium fuels at research reactor, and future plans on neutron factory and hybrid reactor. The former aims at establishment of a new research facility capable of alternating to KUR for future academic research on research reactor containing high quality and high degree application of neutron field and safety management and feature upgrading of nuclear energy. And, the latter aims at development on an accelerator drive uncritical reactor combined an accelerator neutron source and an uncritical reactor. (G.K.)

    The research on neutron radiography in Research Reactor Institute, Kyoto University was begun in 1974 using the E-2 experimental hole which was designed for neutron irradiation. It was reconstructed for the excellent performance as neutron radiography facility by fixing aluminum plugs, a collimator and so on. The research activities thereafter are briefly described. In 1989, the cold neutron facility was installed in the graphite thermal neutron facility, and the experiment on cold neutron radiography became feasible. The reactor in Kyoto University is of the thermal output of 5 MW, and is put to the joint utilization by universities and research institutes in whole Japan. The experimental items carried out so far are enumerated. At present, the main subjects of research are the development of the standard for establishing image evaluation method, the analysis of gas-liquid two-phase flow, the construction of the data base for the literatures and images of neutron radiography, the application of cold neutron radiography, the development of the imaging method using fast neutrons and so on. The thermal neutron radiography and the cold neutron radiography facilities of Kyoto University research reactor are described. The research and activities at Kyoto University research reactor and the investigation of problems are reported. (K.I.) 56 refs

    2007-01-01

    Nepal has recently ratified Kyoto Protocol, which considers justifiable use of resources to limit or reduce the emission of gases that contribute to green house gas inventory in the atmosphere. Nepal's per capita green gas (GHG) emission from energy use is insignificant. However, it is important for Nepal to adopt environmentally friendly energy options based on local resources like hydropower and biomass. Nepal can benefit from the provisions of clean development mechanism (CDM) under the Kyoto Protocol of the United Nations Framework Convention on Climate Change (UNFCC) or carbon funds being promoted by various organizations in order to obtain funding for new projects that reduce GHG emissions (ER). Funding can be generated through Carbon trading in international market as well. In this paper, the country's current contribution to GHG due to energy consumption is evaluated. Options for promoting more sustainable and environmentally friendly projects have also been discussed

  13. The Kyoto Protocol Is Cost-effective

    Directory of Open Access Journals (Sweden)

    Marino Gatto

    2002-06-01

    Full Text Available Despite recent advances, there is a high degree of uncertainty concerning the climate change that would result from increasing atmospheric greenhouse gas concentrations. Also, opponents of the Kyoto Protocol raised the key objection that reducing emissions would impose an unacceptable economic burden on businesses and consumers. Based on an analysis of alternative scenarios for electricity generation in Italy, we show that if the costs in terms of damage to human health, material goods, agriculture, and the environment caused by greenhouse gas emissions are included in the balance, the economic argument against Kyoto is untenable. Most importantly, the argument holds true even if we exclude global external costs (those due to global warming, and account for local external costs only (such as those due to acidic precipitation and lung diseases resulting from air pollution.

    The Canadian government recently stated that it will not meet its Kyoto targets by the end of the first period in 2012, and instead proposed a twofold solution to reduce greenhouse gas emissions. The solutions involve the development of a Clean Air Act that will seek a 50 per cent reduction in emissions by 2050; and, participation in negotiations to determine the next steps for the Kyoto Protocol, post-2012. It was noted that as a ratified member of the Kyoto Protocol, Canada is still legally obligated to achieve its reduction requirements. However, as a co-signatory of the North American Free-Trade Agreement (NAFTA), Canada may be impeded from introducing and maintaining GHG reducing initiative since there are elements of NAFTA which may be used to block efforts that are considered discriminatory to trade. Chapter 11 of NAFTA assigns rights to Canadian, American and Mexican private investors to promote investment, ensure equal treatment and protect their investments against discrimination by NAFTA governments other than their own. These rights may challenge independent action by member states to reduce environmental risks. The authors emphasized that in order to avoid the possibility of legal challenges through Chapter 11 of NAFTA, it is important for the Canadian government to address various aspects of the flexibility mechanisms in the Kyoto Protocol. Three of these mechanisms were designed to reduce the financial burden and technological capacity issues associated with mitigating GHG emissions. These include emissions trading system, clean development mechanism, and joint implementation. The authors presented some policy recommendations to avoid future conflict. 26 refs

  15. A 2004 view of the Kyoto Protocol

    International Nuclear Information System (INIS)

    2004-01-01

    It may not be a household word, but by now the Kyoto Protocol has become a well-known political slogan. It is either ''fundamentally flawed'' (George W. Bush) or it is essential for saving the climate and humanity (Al Gore). There seems to be no in between. The Kyoto Protocol is a treaty to limit (i.e., ration) the use of energy to satisfy the concerns of environmental groups and other believers in global warming catastrophes. This group includes not only certified kooks but also such notables as former Treasury Secretary Paul O'Neill and Sir David King, chief scientific adviser to Her Majesty's government who equates the threat of warming with that of international terrorism. But Kyoto is quite ineffective, that is, it cannot really affect climate or even change the composition of the atmosphere. It is costly. And it is probably also defunct. Where did this treaty come from? Why is it being adopted by some countries but not by others? And what is its likely future?

  16. Two roads to Kyoto: more or less

    Energy Technology Data Exchange (ETDEWEB)

    Stanford, J. [Canadian Auto Workers Union (Canada)

    2003-01-01

    According to this author, in implementing the Kyoto Protocol Canadians are faced with two alternatives: one is consuming less, driving less, and turning down the thermostat, the other is to follow the route of using energy more efficiently, which would allow us to continue to do what we like to do, including driving and staying warm in the winter. The author contends that the federal government's plan relies too heavily on moral suasion, guilt-tripping consumers into reducing their driving and reducing their GHG emissions by turning down their thermostats. The method more likely to succeed would be to encourage fuel-efficient technologies, providing incentives to promote the early commercial production in Canada of low-emission vehicles, along with tax incentives and mandatory market penetration targets. Sensible measures to push automakers to continue improving the average fuel efficiency of new vehicles, shaping and regulating the auto industry to speed up the development of hybrid fuel vehicles and other technological innovations such as continuously variable transmissions, variable valve control and direct injection technologies in engines would also advance the cause of energy efficiency. Regulations regarding motor vehicle recycling, other policies to promote steel recycling, incentives, including higher gasoline taxes, and measures which would mesh with a broader strategy to help Canadians to meet their own Kyoto challenges, are also badly needed. The right decisions on these matters will determine whether ratifying the Kyoto Protocol will be beneficial or detrimental to the Canadian economy.

    2007-01-01

    Full text: We present the results of a survey of an Australian public opinion survey in the area of climate change and energy technologies and compare the results with similar studies conducted in the other major non-Kyoto-adherent party, the United States, as well as to Kyoto-adherent countries including the UK, Japan, Sweden and Spain. We explore some of the differences and similarities in attitudes and understandings. In our survey, Australians place environment, health care and petrol prices as the most important issues facing their country, while in America it is terrorism, health care and the economy and in the UK it is asylum seekers, crime and health care. In many other areas, the differences are considerably smaller and there are some remarkable similarities. Whereas climate change is increasingly cited as the leading environmental issue in most countries surveyed, in Australia, climate change is second to water availability as the top environmental concern. The study examines where climate change and energy technologies fit within these broader national and environmental priorities and identifies the general public's preferred solutions. We find clear support in Australia and the other countries surveyed for renewable energy technologies, particularly solar energy and to a lesser extent wind and biomass energy. We also find considerable disagreement in all countries regarding the future of nuclear power as well as with regard to carbon dioxide capture and storage technologies (albeit the latter with much larger uncertainty). The paper also explores the current knowledge levels of the general public in a number of countries about carbon dioxide emissions and how much as individuals, they are prepared to pay to mitigate greenhouse gas emissions. We find that, in general, at a more detailed level in terms of both attitudes and understandings of energy and climate issues there is considerable agreement across disparate countries Gudged on their national

    The Kyoto University critical assembly experimental facilities belong to the Kyoto University Research Reactor Institute, and are the versatile critical assembly constructed for experimentally studying reactor physics and reactor engineering. The facilities are those for common utilization by universities in whole Japan. During more than ten years since the initial criticality in 1974, various experiments on reactor physics and reactor engineering have been carried out using many experimental facilities such as two solidmoderated cores, a light water-moderated core and a neutron generator. The kinds of the experiment carried out were diverse, and to find out the required data from them is very troublesome, accordingly it has become necessary to make a data base which can be processed by a computer with the data accumulated during the past more than ten years. The outline of the data base, the data base CAEX using personal computers, the data base supported by a large computer and so on are reported. (Kako, I.)

    1993-01-01

    Hall sensors have a variety of applications in magnetic field measurements. The active area of the Hall sensor does not play an important role in measuring of homogeneous magnetic field. Actually Hall sensors are widely used to measure profiles of magnetic fields produced by magnetization currents in samples of HTC superconductors, as well as of LTC ones. Similar techniques are used to measure magnetization of both HTC and LTC superconductors. In these cases Hall sensor operates in highly inhomogeneous magnetic fields. Because of that, Hall sensors with very small active area are required. We developed and tested Hall sensors with active area 100 μm x 100 μm - type M and 50 μm x 50 μm - type V. Here we report on the most imporant parameters of these units, as well as on their properties as differential magnetometer. (orig.)

  20. The Kyoto Protocol. An economic appraisal

    International Nuclear Information System (INIS)

    Grubb, M.

    2000-05-01

    This paper examines the overall economics of the Kyoto Protocol on climate change, in three main parts. The first part explores the structure of the Protocol and how this matches against classical economic criteria of an 'optimal' climate change agreement. This discussion also considers the nature of and reasons for shortcomings, and the prospects for its evolution. Given the various flexibilities in the agreement, the Kyoto Protocol is far more economically efficient in its structure than any previous global environmental agreement. The central conclusion is that, from an economic perspective, the Protocol's structure for industrialised country commitments is as good as could reasonably be expected. The second part of the paper explores more closely the economics of the commitments themselves and how they combine with the various flexibilities, briefly reviewing the available literature and using a simple spreadsheet model of how the commitments might combine with trading mechanisms under a range of assumptions. Flexibility is intrinsic and necessary, but it is argued that the allocations to Russia and Ukraine in particular mean that unlimited flexibility could render the Protocol's commitments weaker in their impacts than is economically desirable to address climate change. It is argued that, should this prove to be the case, access to the large surplus in the transition economies could be used as a control valve to limit the costs of the Protocol to within acceptable limits. Finally, the paper considers the issues of developing country involvement in the Kyoto Protocol, and the Protocol's longer-term impact and evolution, including its impact on technological evolution and dissemination and the evolution of future commitments. It is argued that taking account of such issues critically affects views of the Protocol

    We discuss the contribution of magnetic Skyrmions to the Hall viscosity and propose a simple way to identify it in experiments. The topological Skyrmion charge density has a distinct signature in the electric Hall conductivity that is identified in existing experimental data. In an electrically neutral system, the Skyrmion charge density is directly related to the thermal Hall conductivity. These results are direct consequences of the field theory Ward identities, which relate various physical quantities based on symmetries and have been previously applied to quantum Hall systems.

    Tandem accelerator in Science Faculty, Kyoto University was renewed from 5 MV in the highest terminal voltage of Van de Graaff to 8 MV of Peletron in 1992. And, AMS effective for cosmic ray, dating, environment measurement and so forth is determined to a column of collaborative studies by universities and institutes in Japan. On this renewal, because of using high energy beam transportation of the present tandem accelerator, super high sensitivity measurement of long half-life radioactive isotopes of heavy elements such as {sup 36}Cl, {sup 41}Ca, {sup 129}I and so forth is aimed, although having some limitations due to small magnet. The accelerator is active in characteristics of the middle size tandem accelerator, and developing {sup 14}C measurement for its standard technology, as aiming at {sup 36}Cl measurement, at first. As a result, in this tandem accelerator stable and high beam transmittance could be obtained by adding a slit at negative ion source to make emittance of incident beam smaller. {sup 14}C/{sup 12}C ratio of Modan`s sample obtained by graphitizing NBS oxalic acid and Ded`s sample consisting of mineral graphite produced in Sri Lanka are measured to confirm better reproductivity of this system. Future development of successive incident method is planned to test actual carbon samples. (G.K.)

    Helical systems are an attractive candidate for magnetic fusion reactor. Recently, there has been great progress in theoretical research of three dimensional magnetic field structures, resulting in several kinds of confinement optimization being proposed for toroidal magnetic confinement system. For example, some sophisticated ideas have appeared on stage such as quasi-helical symmetry and quasi-isodynamic system. To find experimentally which way is the best Optimisation, a new helical axis heliotron device, so called 'Heliotron J', is under construction in the Institute of Advanced Energy, Kyoto University, Japan. In this conference, the basic concept and the present status will be presented. In the conventional plane axis helical system, it was difficult to have both good particle confinement and good MHD stability simultaneously. The goal of Heliotron J project is to clarify their compatibility in the spatial axis toroidal device. The best way for Optimising the helical magnetic field configuration will be explored by investigating the plasma response to the change in the field components. The main subjects for plasma experiment are: demonstration of the existence of good magnetic flux surfaces, reduction of neoclassical transport in collisionless regime, MHD Stabilisation in high β plasma, controllability of bootstrap current, good confinement of high energy particles

    A not well managed drastic reduction of greenhouse emissions might result in significant decrease of living standards, but without such reduction efforts, climate change might have five to twenty times higher costs. Thus, while indicating estimated consequences or evolutions of greenhouse emissions and temperature, the author stresses the need of emission reduction. She discusses the role of economic instruments which can be used in policies aimed at the struggle against climate change. She recalls the emission reduction commitments specified in the Kyoto protocol, discusses the present status, operation and results of the international emission trading scheme, the lessons learned after the first years of operation, comments the involvement of emerging countries in relationship with another mechanism defined in the protocol: the Clean Development Mechanism

    Barnett, Jon; Dessai, Suraje; Webber, Michael

    2004-01-01

    A range of energy-economy models forecast losses to members of the Organisation of Petroleum Exporting Countries (OPEC) should the Kyoto Protocol come into force. These forecasts are a powerful influence in the United Nations Framework Convention on Climate Change negotiations. They are used by OPEC to advance the agenda on the impacts of response measures, covertly arguing for compensation for lost oil revenues arising from implementation of the Protocol. This paper discusses this issue, and explores the key assumptions of these models and their uncertainties. Assumptions about carbon leakage, future availability of oil reserves, substitution, innovation, and capital turnover are considered. The paper suggests that losses will not affect OPEC countries equally, and that these losses are not likely to be as substantial as the models forecast. A range of policy measures are proposed to lessen any impact the Protocol may have on OPEC

  12. Kyoto commitments: CHP will help the UK

    1998-01-01

    In order to meet the United Kingdom's targets for carbon dioxide emissions reduction, agreed at the Kyoto Summit, the UK Government is promoting the use of combined heat and power (CHP) plants. Such schemes need to offer over 70% efficiency, have on-site or nearby heat uses, and allow flexibility for the export of electricity where this is appropriate. Electricity trading arrangements will need to be re-organised in line with similar commodities, in order to facilitate and promote the growth of CHP and renewable energy schemes. Financial incentives and regulation of electricity prices will also contribute to the promotion of CHP schemes, ultimately leading to reduced CO 2 pollution as a result of the growth in the UK's CHP capacity.

    The Kyoto Meteor Radar is a monostatic coherent pulsed Doppler radar operating on the frequency of 31.57 MH. The system is computer controlled and uses radio interferometry for echo height determination. The antenna, an improvement, can be directed either to the north or the east. The system has been continuously collecting data on winds at meteor heights by radar observation. The meteor echo rate was also measured, the echo rate distribution with height and the daily variation in height integrated echo rate are discussed. Investigations of atmospheric tides are being pursued by cooperative observations. A novel approach to the study of gravity waves was attempted using the meteor radar which is able to detect the horizontal propagation of the waves by observing the changing phase through the region illuminated by the radar

    Since 1990, Canada's greenhouse gas emissions are up 20 per cent, meaning that Canada must reduce its emissions by 30 per cent between 2005 and 2010 to meet its commitment under the Kyoto Protocol. Ottawa has indicated that no one sector of the economy should bear the burden of this adjustment. The energy production sector accounts for almost 40 per cent of all greenhouse gas emissions. Our per capita emissions have risen 50 per cent faster than emissions in the United States. The authors compared our situation to that of Europe, where only a 5 per cent reduction is required, which can be explained by high taxes on energy users, and the closure of obsolete East German capacity which led to reductions of 100 million tonne in carbon dioxide emissions. Transportation is the second largest generator of greenhouse gas emissions with approximately 16 per cent. A quick overview of the energy sector was provided, touching on topics such as electric power generation, including coal-fired electrical production, and tar sands with its increasing importance to Canada's economy. Ottawa has released a plan in October 2002, where it indicates that industrial emitters will be required to cut 80 million tonnes through investments in more efficient technology. Tighter vehicle fuel and home insulation standards would account for 35 to 40 million tonnes of reduction, and 40 million tonnes would come from agriculture and forest management. It means there is a 60 million shortfall, and the tar sands industry will more than likely have to adjust, raising investor uncertainty over further development in that area. Climate change is unlikely to be modified by meeting the objectives of the Kyoto Protocol. The authors questioned whether the government shouldn't instead devote its resources to addressing the actual impact of climate change. 9 figs

    Transport phenomena in two dimensional semiconductors have revealed unusual properties. In this thesis these systems are considered and discussed. The theories explain the Integral Quantum Hall Effect (IQHE) and the Fractional Quantum Hall Effect (FQHE). The thesis is composed of five chapters. The first and the second chapters lay down the theory of the IQHE, the third and fourth consider the theory of the FQHE. Chapter five deals with the statistics of particles in two dimension.

  2. Hall viscosity of hierarchical quantum Hall states

    Using methods based on conformal field theory, we construct model wave functions on a torus with arbitrary flat metric for all chiral states in the abelian quantum Hall hierarchy. These functions have no variational parameters, and they transform under the modular group in the same way as the multicomponent generalizations of the Laughlin wave functions. Assuming the absence of Berry phases upon adiabatic variations of the modular parameter τ, we calculate the quantum Hall viscosity and find it to be in agreement with the formula, given by Read, which relates the viscosity to the average orbital spin of the electrons. For the filling factor ν =2/5 Jain state, which is at the second level in the hierarchy, we compare our model wave function with the numerically obtained ground state of the Coulomb interaction Hamiltonian in the lowest Landau level, and find very good agreement in a large region of the complex τ plane. For the same example, we also numerically compute the Hall viscosity and find good agreement with the analytical result for both the model wave function and the numerically obtained Coulomb wave function. We argue that this supports the notion of a generalized plasma analogy that would ensure that wave functions obtained using the conformal field theory methods do not acquire Berry phases upon adiabatic evolution.

  3. Kyoto, coal and sharing the cost burden

    Daley, J.

    1998-01-01

    Parties to the UN Framework Convention on Climate Change (the Rio Treaty) at their first conference in 1995 agreed that the commitments entered into under the Convention were 'not adequate' to achieve its objective. These nations determined to proceed to strengthen those commitments under a protocol to be prepared for the third conference at Kyoto. Also it was to contain 'quantified emissions limitation objectives' (binding targets) on the industrial countries. For such targets to be consistent with Australia's interests, they would need to recognise Australia's relatively fast population and economic growth (both of which imply relatively faster growth in emissions), the increasing preponderance of energy intensive industries in the Australian economy, and our dependence on the export of energy intensive manufactures (like aluminium and other metals) and direct export of fossil fuels (including coal and natural gas). Major parties to the protocol negotiations - the USA and the EU - were advocates of uniform percentage emissions reductions from 1990 levels. Uniform percentage reductions, however intuitively appealing, impose widely different costs on different parties on account of their different circumstances. Australia would have been penalised by uniform reductions because our projected business-as-usual emissions trajectory is relatively steep, and measures adopted internationally to mitigate greenhouse gas emissions impact disproportionately on this economy (notably on account of reduced demand for Australian coal). The accompanying charts depict ABAREs 'less stringent' emissions scenario - addressing a goal of stabilising industrial countries' emissions of C0 2 rather than reducing them. ABARE's simulation for Australia by sector shows big negative impacts on output of non-ferrous metals, iron and steel, and coal. The metals industries, directly or indirectly are the coal industry's most important domestic customers. It is argued that because of the impact

    Commitments obtained by the Kyoto protocol will end in 2012. An impressive series of conferences - Bali (2007), Copenhagen (2009), Cancun (2010) to mention the main ones - were organised to prepare the post-2012 regime. Everything was supposed to be decided at the Copenhagen meeting but the state representatives came up against the obstacle. The pre-Copenhagen hope has given place to disillusion and has led to a turn-off towards a weekly coordinated regime which requires a strategic revision of approaches. This book presents the lessons learnt from the relative failure of these negotiations and proposes new paths for the future. It puts forward some strategic stakes that have to be taken into account for the future: the equity between very heterogeneous countries and populations, the industrial competitiveness, the carbon leaks and the violation of the most ambitious climate policies due to the heterogeneity of commitment levels, and the geopolitical reality. The world will have to live for a long time with heterogeneous carbon prices, themselves reflecting heterogeneous commitment levels. New modalities have to be defined which would manage to combine justice and efficiency. Two complementary paths are developed in this book: the establishing of adjustment mechanisms at borders and of international sectoral agreements. (J.S.)

  5. Emission Trading under the Kyoto Protocol

    Energy Technology Data Exchange (ETDEWEB)

    Holtsmark, Bjart; Hagem, Cathrine

    1998-12-01

    This report discusses the potential gains from emission trading and raises some crucial questions. It shows that the total costs of the Kyoto Protocol could be reduced by about 95% through emission trading. Emission trading is an option also in the domestic arenas. The governments of the Annex B countries may allocate emission quotas to local enterprises as emission permits. Thus new markets for greenhouse gas emission quotas may emerge, domestically and internationally. It is emphasized that emission trading at the national and international levels must be discussed separately. The Nordic governments, for example, will find several good reasons for supporting emission trading at the international level if not necessarily domestically. The Nordic countries have already implemented domestic taxes on CO{sub 2} emissions and this tax policy could be sustained while these governments support and take part in emission trading at the international level.The report also considers a possible side effect of emission trading: free emission trading among Annex B countries could reduce the total abatement compared to a non-tradable policy as a consequence of the fact that some of the countries that are in transition to a market economy may be given emission limitations above their business-as-usual emissions. 40 refs., 7 figs., 4 tabs.

  6. From Kyoto to Copenhagen: the carbon markets expansion

    International Nuclear Information System (INIS)

    Alberola, Emilie; Fages, Emmanuel

    2009-01-01

    The article examines the development of carbon markets in the world. Such markets are the main economic instrument of the international climate policy established by the Kyoto Protocol in 1997 and are being implemented by most industrialized countries. They are experimented by Europe since 2005 for industrial facilities and since 2008 by industrialized countries under Kyoto. The development of carbon markets will likely continue beyond 2012, when the Kyoto Protocol expires. Their expansion will be largely determined by the future international climate policy to be negotiated in Copenhagen in December 2009 and by the commitment of the largest economies like the United States. The authors describe the emergence of carbon markets, their basic principles and the experience of Kyoto and European markets. Then, they deal with the expected developments beyond 2012

    The present report reflects findings from a study on the realization of and prospects for the Kyoto Protocol. The purpose of the study was (1) to obtain insights into the factors that enabled the realization of the Kyoto Protocol, in particular the interactions among major parties involved; (2) to assess the future opportunities and threats of the Kyoto Protocol, in particular against the backdrop of an increasingly globalised world. The study was conducted from February up to December 2003 by (a) reviewing the literature, especially publications on the negotiation history of the Kyoto process, the social interactions enabling the realization of the Protocol, analyses of strengths and weaknesses, and future climate regimes; (b) conducting a series of interviews with representatives from government, academia, non-governmental organisations, and business, who have been - directly or indirectly - involved in the Kyoto process; (c) internal discussions,brainstorming and analysing the Protocol's strengths and weaknesses, possible future scenarios (including policy options), and the management of a possible failure of the Kyoto Protocol. The present report reflects and integrates the different sources. The first section deals with the past and the present. It discusses how the Kyoto Protocol could be realized despite the divergent interests, reflects on its architecture, and analyses major strengths and weaknesses. In the second section, we present possible future scenarios. We explore how different combinations of domestic and international commitment provide possible realities that national government may face when crafting climate policy. The third section provides an in-depth analysis of the possible event that the Kyoto Protocol fails. We discuss its definition and policy implications. The final section is reserved for overall conclusions and policy recommendations

    The Beyond Kyoto conference in Aarhus March 2009 was organised in collaboration with other knowledge institutions, businesses and authorities. It brought together leading scientists, policy-makers, authorities, intergovernmental organisations, NGO's, business stakeholders and business organisations. The conference was a joint interdisciplinary project involving many academic areas and disciplines. These conference proceedings are organised in central and recurring themes that cut across many debates on climate change, the climatic challenges as well as the solutions. In the front there is a short presentation of the conference concept. Part I of the proceedings focuses on issues related to the society - covering climate policy, law, market based instruments, financial structure, behaviour and consumption, public participation, media communication and response from indigenous peoples etc. Part II of the proceedings concerns the scientific knowledge base on climate related issues - covering climate change processes per se, the potential impacts of projected climate change on biodiversity and adaptation possibilities, the interplay between climate, agriculture and biodiversity, emissions, agricultural systems, increasing pressure on the functioning of agriculture and natural areas, vulnerability to extreme weather events and risks in respect to sea-level rise etc. The conference proceedings committee consists of four professors from Aarhus University: Jens-Christian Svenning, Jørgen E Olesen, Mads Forchhammer and Ellen Margrethe Basse. Aarhus University's Climate Secretariat has had the overall responsibility for coordinating the many presentations, as well as the practical side of arranging the conference and supporting the publication of papers. As Head of the Climate Secretariat and Chair of Aarhus University's Climate Panel, I would like to thank everyone for their contribution. This applies both to the scientific and the practical efforts. Special thanks to

    We discover an intrinsic superspin Hall current: an injected charge supercurrent in a Josephson junction containing heavy normal metals and a ferromagnet generates a transverse spin supercurrent. There is no accompanying dissipation of energy, in contrast to the conventional spin Hall effect. The physical origin of the effect is an antisymmetric spin density induced among transverse modes ky near the interface of the superconductor arising due to the coexistence of p -wave and conventional s -wave superconducting correlations with a belonging phase mismatch. Our predictions can be tested in hybrid structures including thin heavy metal layers combined with strong ferromagnets and ordinary s -wave superconductors.

    An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered. Copyright © 2011 Elsevier Inc. All rights reserved.

    The nuclear plant accident at Fukushima in the wake of the Great East Japan Earthquake and tsunami has had a major impact on the energy strategy of Japan and the world. From a global perspective, approach to energy is of greater and greater consequence. The Global Center of Excellence (COE) Program of the Ministry of Education, Culture, Sports, Science and Technology of Japan, with the support of university faculty members, has established an international education and research platform to foster educators, researchers, and policy makers who can develop technologies and propose policies for establishing a CO2 zero-emission society no longer dependent on fossil fuels by the year 2100. Since 2008, a program called “Energy Science in the Age of Global Warming—Toward a CO2 Zero-Emission Energy System” has been in progress at Kyoto University.

    On March 11, 2011, the Great East Japan Earthquake devastated the Tohoku region, which led to a tsunami and a nuclear disaster. While these three disasters caused tremendous physical damage, their psychological impact remains unclear. The present study evaluated traumatic responses, internalizing (i.e., anxiety and depression), and externalizing (i.e., anger) symptoms among Japanese young people in the immediate aftermath and 2.5 years later. A total of 435 undergraduates were recruited from universities in three differentially exposed regions: Fukushima, Tokyo, and Kyoto. They completed a set of questionnaires retrospectively (i.e., September to December 2013) to measure their traumatic responses, anxiety and depressive symptoms, functional impairment, and anger immediately after the disaster and 2.5 years later. Participants in Tokyo had the highest level of traumatic response and internalizing symptoms immediately after the earthquake, whereas those in Fukushima had significantly higher levels of trait anger, anger-in (holding one's anger in), and anger-out (expressing one's anger externally). In Kyoto, the levels of anxiety and depression after 2.5 years were significantly higher than they were immediately after the disasters. In conclusion, anger symptoms were high among young people who lived at or near the center of the disasters, while anxiety and depression were high among those who lived far away from the disasters. These findings suggest the importance of providing mental health services to young people who did not live near the disaster area as well as to those living in the directly affected area.

    The Intergovernmental Panel on Climate Change (IPCC) was established by the World Meteorological Organization and the United Nations Environment Program in 1988 to assess the available scientific, technical, and socioeconomic information in the field of climate change. The most recent report of the IPCC concluded that ``Our ability to quantify the human influence on global climate is currently limited because the expected signal is still emerging from the noise of natural variability, and because there are uncertainties in key factors. These include the magnitudes and patterns of long-term variability and the time-evolving pattern of forcing by, and response to, changes in concentrations of greenhouse gases and aerosols, and land surface changes. Nevertheless the balance of evidence suggests that there is a discernible human influence on global climate. The first and second Conference of the Parties in 1995 and 1996 agreed to address the issue of greenhouse gas emissions for the period beyond 2000, and to negotiate quantified emission limitations and reductions for the third Conference of the Parties. On December 1 through 11, 1997, representatives from more than 160 countries met in Kyoto, Japan, to negotiate binding limits on greenhouse gas emissions for developed nations. The resulting Kyoto Protocol established emissions targets for each of the participating developed countries--the Annex 1 countries--relative to their 1990 emissions levels. 114 refs., 138 figs., 33 tabs.

    This paper presented a demonstration project in the City of Kyoto, Japan, which is aimed at determining if a Public Car System is an economically viable option for the twenty first century. The Kyoto electric vehicle (EV) car sharing project comprises advanced systems for EV reservation, check-out and return, and fleet operation and management. The most unique feature of this project is that it utilizes the ever expanding Internet and advanced mobile phones with Internet capabilities. Initially, 35 two-seater EVs will be shared by employees and visitors for business-related trips on weekdays and by tourists on weekends. The car sharing will be only short-term for only a single trip. The EV can be checked out and returned to any service depot located at railroad stations, major business centers and tourist attractions for user convenience. The ultimate goal of the project is to promote energy and resource conservation while providing adequate levels of mobility for people. Converting existing fleets to EVs which produce no exhaust gases is considered to be a viable solution to the problem of air pollution caused by traffic jams. tabs., figs.

    With the use of the Kyoto University Critical Assembly (KUCA), a joint reactor laboratory course of graduate level is offered every summer since 1975 by nine associated Japanese universities (Hokkaido University, Tohoku University, Tokyo Institute of Technology, Musashi Institute of Technology, Tokai University, Nagoya University, Osaka University, Kobe University of Mercantile Marine and Kyushu University) in addition to a reactor laboratory course of undergraduate level for Kyoto University. These courses are opened for three weeks (two weeks for the joint course and one week for the undergraduate course) to students majoring in nuclear engineering and a total of 1,360 students have taken the course in the last 21 years. The joint course has been institutionalized with the background that it is extremely difficult for a single university in Japan to have her own research or training reactor. By their effort, the united faculty team of the joint course have succeeded in giving an effective, unique one-week course, taking advantage of their collaboration. Last year, an enquete (questionnaire survey) was conducted to survey the needs for the educational experiments of graduate level and precious data have been obtained for promoting reactor laboratory courses.

    1998-10-01

    The Intergovernmental Panel on Climate Change (IPCC) was established by the World Meteorological Organization and the United Nations Environment Program in 1988 to assess the available scientific, technical, and socioeconomic information in the field of climate change. The most recent report of the IPCC concluded that ''Our ability to quantify the human influence on global climate is currently limited because the expected signal is still emerging from the noise of natural variability, and because there are uncertainties in key factors. These include the magnitudes and patterns of long-term variability and the time-evolving pattern of forcing by, and response to, changes in concentrations of greenhouse gases and aerosols, and land surface changes. Nevertheless the balance of evidence suggests that there is a discernible human influence on global climate. The first and second Conference of the Parties in 1995 and 1996 agreed to address the issue of greenhouse gas emissions for the period beyond 2000, and to negotiate quantified emission limitations and reductions for the third Conference of the Parties. On December 1 through 11, 1997, representatives from more than 160 countries met in Kyoto, Japan, to negotiate binding limits on greenhouse gas emissions for developed nations. The resulting Kyoto Protocol established emissions targets for each of the participating developed countries--the Annex 1 countries--relative to their 1990 emissions levels. 114 refs., 138 figs., 33 tabs

  5. Emission trading in Slovakia is not bound to Kyoto

    After Pentagon published its report problems related to changes in climate became an important discussion topic again. The report indicates that future temperature increase could have fatal impacts like flooding of Netherlands. Representatives of Slovak National Climate Program do not completely share this view. They consider it to be the worst scenario - catastrophic scenario. And they are also positive that the emissions of greenhouse gases that are the main reason for these changes of climate will decrease. EU is currently working on Directives that will support one of the possible solutions - emission trading and will make this trade independent from ratification of the Kyoto protocol. The basic principle is simple - a country with production of the greenhouse gases below the legally set level or below the level set out by international agreement on climatic changes will have some spare emission quotas that can be traded i.e. sold to a country that produces more gases then allowed. And based on such an agreement signed between a Slovak and Japanese company, Japan will be allowed to produce more greenhouse gases if it can prove that there is an area in the world where the production is below the limit. But, at the same time, it will have to pay for this over-production. Starting next year over 12-thousand companies will be allowed to participate in this business. At the moment an act on emission trading is being prepared in Slovakia. It should have been completed by end of January but the approval process is being delayed. Similar acts are under preparation also in other countries and not even the EU member states have passed them yet. The National Allocation Plan in Slovakia should distribute the emission quotas to about 200 companies. Many European politicians consider the emission trade an effective economic tool provided it will be used as motivation for decrease of greenhouse gas production. And so all companies participating in this project will handle in

  6. Carbon Sequestered, Carbon Displaced and the Kyoto Context

    1999-01-01

    The integrated system that embraces forest management, forest products, and land-use change impacts the global carbon cycle - and hence the net emission of the greenhouse gas carbon dioxide - in four fundamental ways. Carbon is stored in living and dead biomass, carbon is stored in wood products and landfills, forest products substitute in the market place for products made from other materials, and forest harvests can be used wholly or partially to displace fossil fuels in the energy sector. Implementation of the Kyoto Protocol to the United Nations Framework Convention on Climate Change would result in the creation of international markets for carbon dioxide emissions credits, but the current Kyoto text does not treat all carbon identically. We have developed a carbon accounting model, GORCAM, to examine a variety of scenarios for land management and the production of forest products. In this paper we explore, for two simple scenarios of forest management, the carbon flows that occur and how these might be accounted for under the Kyoto text. The Kyoto protocol raises questions about what activities can result in emissions credits, which carbon reservoirs will be counted, who will receive the credits, and how much credit will be available? The Kyoto Protocol would sometimes give credits for carbon sequestered, but it would always give credits when fossil-fuel carbon dioxide emissions are displaced

    The Kyoto University Research Reactor Institute was established in 1963 as a research institute for all universities in Japan utilizing the facilities in common. The construction of a document data base has been undertaken in commemoration of the 20th anniversary of the institute. The data base concerns the research works performed at the institute and also the publications and reports on the research made by the personnel belonging to the institute. Input data are gathered from concerned researchers. In this interim report, the structure and contents of this data base are shortly described. One of the features of this data base is that it handles data with both Japanese and English at the same time. (Aoki, K.)

    Spin Hall effects are a collection of relativistic spin-orbit coupling phenomena in which electrical currents can generate transverse spin currents and vice versa. Despite being observed only a decade ago, these effects are already ubiquitous within spintronics, as standard spin-current generators and detectors. Here the theoretical and experimental results that have established this subfield of spintronics are reviewed. The focus is on the results that have converged to give us the current understanding of the phenomena, which has evolved from a qualitative to a more quantitative measurement of spin currents and their associated spin accumulation. Within the experimental framework, optical-, transport-, and magnetization-dynamics-based measurements are reviewed and linked to both phenomenological and microscopic theories of the effect. Within the theoretical framework, the basic mechanisms in both the extrinsic and intrinsic regimes are reviewed, which are linked to the mechanisms present in their closely related phenomenon in ferromagnets, the anomalous Hall effect. Also reviewed is the connection to the phenomenological treatment based on spin-diffusion equations applicable to certain regimes, as well as the spin-pumping theory of spin generation used in many measurements of the spin Hall angle. A further connection to the spin-current-generating spin Hall effect to the inverse spin galvanic effect is given, in which an electrical current induces a nonequilibrium spin polarization. This effect often accompanies the spin Hall effect since they share common microscopic origins. Both can exhibit the same symmetries when present in structures comprising ferromagnetic and nonmagnetic layers through their induced current-driven spin torques or induced voltages. Although a short chronological overview of the evolution of the spin Hall effect field and the resolution of some early controversies is given, the main body of this review is structured from a pedagogical

  10. Paired Hall states

    International Nuclear Information System (INIS)

    Greiter, M.

    1992-01-01

    This dissertation contains a collection of individual articles on various topics. Their significance in the corresponding field as well as connections between them are emphasized in a general and comprehensive introduction. In the first article, the author explores the consequences for macroscopic effective Lagrangians of assuming that the momentum density is proportional to the flow of conserved current. The universal corrections obtained for the macroscopic Lagrangian of a superconductor describe the London Hall effect, and provide a fully consistent derivation of it. In the second article, a heuristic principle is proposed for quantized Hall states: the existence and incompressibility of fractionally quantized Hall states is explained by an argument based on an adiabatic localization of magnetic flux, the process of trading uniform flux for an equal amount of fictitious flux attached to the particles. This principle is exactly implemented in the third article. For a certain class of model Hamiltonians, the author obtains Laughlin's Jastrow type wave functions explicitly from a filled Landau level, by smooth extrapolation in quantum statistics. The generalization of this analysis to the torus geometry shows that theorems restricting the possibilities of quantum statistics on closed surfaces are circumvented in the presence of a magnetic field. In the last article, the existence is proposed of a novel incompressible quantum liquid, a paired Hall state, at a half filled Landau level. This state arises adiabatically from free fermions in zero magnetic field, and reduces to a state previously proposed by Halperin in the limit of tightly bound pairs. It supports unusual excitations, including neutral fermions and charge e/4 anyons with statistical parameter θ = π/8

  11. Submission to the British Columbia government on the Kyoto Protocol

    2002-09-01

    The Business Council provided its comments concerning the Kyoto Protocol and climate change to the government of British Columbia, recommending that a clear position be established quickly on the matter. The adopted position should also be disseminated broadly to allow stake holders sufficient time to prepare for the upcoming meetings of the Joint Ministers and First Ministers. The federal government has announced that the decision on whether to ratify the Kyoto Protocol will be made before the end of 2002, and this decision will have numerous effects on the people of British Columbia, businesses, workers, and consumers alike. The Business Council of British Columbia believes that the unique interests of the province can best be protected by a proactive approach. Actions plans are being prepared by several of the other provinces and territories, who have already stated their position concerning the Kyoto Protocol. The long-term risks of climate change for British Columbia have not been determined nor have the elements of a provincial approach. The following elements should be included in British Columbia's position on the Kyoto Protocol, according to the Business Council of British Columbia: (1) a credible and cost-effective implementation plan that does not unduly burden the province and other jurisdictions must be developed before Canada decides to ratify the Protocol. British Columbia should go on the record stating it does not support the ratification of the Kyoto Protocol in its present form. (2) the province should advocate for a national approach to climate change that can be achieved within a reasonable time frame, reflects the long-term nature of the problem, and is in agreement with the economic development objectives of British Columbia, (3) a plan detailing how the province intends to deal with the growth of greenhouse gas emissions should supplement and support the position of the province on the Kyoto Protocol. Consumers and business should be engaged

  12. Guild Hall retrofit

    Energy Technology Data Exchange (ETDEWEB)

    1984-08-01

    This report demonstrates the economic viability of an exterior rewrap retrofit performed on a public community facility for the performing arts. This facility originally consisted of two mess halls built by the American army. The exterior retrofit consisted of constructing a super-insulated passageway to link the two halls as well as completely wrapping the facility with six millimetre polyethylene to provide an airtight barrier. The roofs and walls were reinsulated and insulation levels were increased to RSI 10.5 in the ceilings and RSI 7.7 in the walls. The installation of a propane fuelled furnace was also included in the retrofit package. Prior to the renovations and retrofitting, the Guild Hall facility was almost unusable. The demonstration project transformed the cold, drafty buildings into an attractive, comfortable and functional centre for the performing arts. Heating requirements have been reduced to 500 MJ/m {sup 2} of floor space annually compared to a predicted 1,760 MJ/m{sup 2} of floor space based on HOTCAN analysis of the heating requirements without the energy conservation measures. 9 figs., 10 tabs.

    Lütken, C A

    2014-01-01

    We investigate a finite size "double scaling" hypothesis using data from an experiment on a quantum Hall system with short range disorder [1-3]. For Hall bars of width w at temperature T the scaling form is w(-mu)T(-kappa), where the critical exponent mu approximate to 0.23 we extract from the data is comparable to the multi-fractal exponent alpha(0) - 2 obtained from the Chalker-Coddington (CC) model [4]. We also use the data to find the approximate location (in the resistivity plane) of seven quantum critical points, all of which closely agree with the predictions derived long ago from the modular symmetry of a toroidal sigma-model with m matter fields [5]. The value nu(8) = 2.60513 ... of the localisation exponent obtained from the m = 8 model is in excellent agreement with the best available numerical value nu(num) = 2.607 +/- 0.004 derived from the CC-model [6]. Existing experimental data appear to favour the m = 9 model, suggesting that the quantum Hall system is not in the same universality class as th...

  18. Ocean iron fertilization in the context of the Kyoto protocol and the post-Kyoto process

    International Nuclear Information System (INIS)

    Bertram, Christine

    2010-01-01

    Ocean iron fertilization is currently discussed as a potential measure to mitigate climate change by enhancing oceanic CO 2 uptake. Its mitigation potential is not yet well explored, and carbon offsets generated through iron fertilization activities could currently not be traded on regulated carbon markets. Still, commercial interests in ocean iron fertilization already exist, which underlines the need to investigate a possible regulatory framework for it. To this end, I first discuss important basic aspects of ocean iron fertilization, namely its scientific background, quantitative potential, side effects, and costs. In a second step, I review regulatory aspects connected to ocean iron fertilization, like its legal status and open access issues. Moreover, I analyze how the regulations for afforestation and reforestation activities within the framework of the Kyoto Clean Development Mechanism (CDM) could be applied to ocean iron fertilization. Main findings are that the quantitative potential of ocean iron fertilization is limited, that costs are higher than initially hoped, and that potential adverse side effects are severe. Moreover, the legal status of ocean iron fertilization is currently not well defined, open access might cause inefficiencies, and the CDM regulations could not be easily applied to ocean iron fertilization.

  19. Kyoto and beyond : A plan of action to meet and exceed Manitoba's Kyoto targets

    International Nuclear Information System (INIS)

    2002-10-01

    This document represents the next step in Manitoba's effort to mitigate the effects of climate change. A message from the Manitoba Premier and the Minister of Conservation of Manitoba are included in the introduction. The Action Plan is based in part on the discussion among climate experts and public input gathered in the course of the 2001 task force and the 2001 public forum on climate change. A rise in average global temperatures is affecting most of the planet, which is due in part to the upsetting of the balance of greenhouse gases in the atmosphere as a result of human activities. It is affecting weather patterns, water, agriculture, forests, health and welfare, and life in the North. The Manitoba government is committed to meeting and exceeding the reduction targets set under the Kyoto Protocol through renewable electricity, Selkirk conversion, ethanol, methane capture, and other measures targeted toward industry. Energy efficiency also plays a big part in the process of reducing greenhouse gas emissions. The government is leading by example, and also investing in knowledge. It is promoting technology development and innovation while enhancing awareness and understanding. All sectors are being encouraged to implement appropriate measures. The various initiatives undertaken by each department and organization under each of those headings are described. figs

    Commitments obtained by the Kyoto protocol will end in 2012. An impressive series of conferences - Bali (2007), Copenhagen (2009), Cancun (2010) to mention the main ones - were organised to prepare the post-2012 regime. Everything was supposed to be decided at the Copenhagen meeting but the state representatives came up against the obstacle. The pre-Copenhagen hope has given place to disillusion and has led to a turn-off towards a weekly coordinated regime which requires a strategic revision of approaches. This book presents the lessons learnt from the relative failure of these negotiations and proposes new paths for the future. It puts forward some strategic stakes that have to be taken into account for the future: the equity between very heterogeneous countries and populations, the industrial competitiveness, the carbon leaks and the violation of the most ambitious climate policies due to the heterogeneity of commitment levels, and the geopolitical reality. The world will have to live for a long time with heterogeneous carbon prices, themselves reflecting heterogeneous commitment levels. New modalities have to be defined which would manage to combine justice and efficiency. Two complementary paths are developed in this book: the establishing of adjustment mechanisms at borders and of international sectoral agreements. (J.S.)

    Urquhar, I.

    2002-11-01

    In this document, the author examines the constraints that would be placed on policy makers in the event of the implementation of the Kyoto Protocol, and how it would affect trade agreements and federalism in Canada. A description of the Protocol and the concessions (carbon sinks and international emissions trading) gained by Canada are presented at the beginning of the document. The author offers several conclusions that could disturb both proponents and opponents of the Kyoto Protocol. It is said that the implementation of Kyoto can take a route other than that of drastic domestic emissions reductions, and this position is explored in the second section. The author indicates that corporate competitiveness could be boosted by strict environmental regulations. A range of policies that could be adopted by Canada, as proposed by numerous organizations, are highlighted in the third section of the document. The point of the World Trade Organization and the constraints imposed are not necessarily preventing all types of actions. However, the author is of the opinion that the North America Free Trade Agreement represents a real threat to the implementation of the Kyoto Protocol. Finally, it is indicated that Canada requires a national electricity policy, where big hydro utilities and public investment have major roles to play.

  5. The costs and benefits of early action before Kyoto compliance

    International Nuclear Information System (INIS)

    Pan, Haoran; Regemorter, D. van

    2004-01-01

    Transaction costs have negative effects on emissions trading. Recent debates on the Kyoto Protocol have emphasized the potential threat of transaction costs to the implementation of emissions trading for the Protocol and consequently to the successful implementation of the Protocol. One way to suppress transaction costs is to use experience. In line with the EU Green Paper, we propose that an experimental early action before the Kyoto period could be helpful to reduce the transaction costs in emissions trading for the Kyoto compliance. However, because early action will incur additional costs, the final gain due to early action will be the cost-saving net of the costs of early action. This paper explores the relationship between the transaction costs in emissions trading and the early action effort to reduce transaction costs in the case of Kyoto Protocol. We find that in general early action can effectively offset transaction costs and thus are economically efficient. Only in the case of high transaction costs and constantly slow learning process, early action may become inefficient

  8. Ocean fertilization, carbon credits and the Kyoto Protocol

    Science.gov (United States)

    Westley, M. B.; Gnanadesikan, A.

    2008-12-01

    Commercial interest in ocean fertilization as a carbon sequestration tool was excited by the December 1997 agreement of the Kyoto Protocol to the United Nations Convention on Climate Change. The Protocol commits industrialized countries to caps on net greenhouse gas emissions and allows for various flexible mechanisms to achieve these caps in the most economically efficient manner possible, including trade in carbon credits from projects that reduce emissions or enhance sinks. The carbon market was valued at 64 billion in 2007, with the bulk of the trading (50 billion) taking place in the highly regulated European Union Emission Trading Scheme, which deals primarily in emission allowances in the energy sector. A much smaller amount, worth $265 million, was traded in the largely unregulated "voluntary" market (Capoor and Ambrosi 2008). As the voluntary market grows, so do calls for its regulation, with several efforts underway to set rules and standards for the sale of voluntary carbon credits using the Kyoto Protocol as a starting point. Four US-based companies and an Australian company currently seek to develop ocean fertilization technologies for the generation of carbon credits. We review these plans through the lens of the Kyoto Protocol and its flexible mechanisms, and examine whether and how ocean fertilization could generate tradable carbon credits. We note that at present, ocean sinks are not included in the Kyoto Protocol, and that furthermore, the Kyoto Protocol only addresses sources and sinks of greenhouse gases within national boundaries, making open-ocean fertilization projects a jurisdictional challenge. We discuss the negotiating history behind the limited inclusion of land use, land use change and forestry in the Kyoto Protocol and the controversy and eventual compromise concerning methodologies for terrestrial carbon accounting. We conclude that current technologies for measuring and monitoring carbon sequestration following ocean fertilization

    2015-01-01

    This Phase II project is developing a magnesium (Mg) Hall effect thruster system that would open the door for in situ resource utilization (ISRU)-based solar system exploration. Magnesium is light and easy to ionize. For a Mars- Earth transfer, the propellant mass savings with respect to a xenon Hall effect thruster (HET) system are enormous. Magnesium also can be combusted in a rocket with carbon dioxide (CO2) or water (H2O), enabling a multimode propulsion system with propellant sharing and ISRU. In the near term, CO2 and H2O would be collected in situ on Mars or the moon. In the far term, Mg itself would be collected from Martian and lunar regolith. In Phase I, an integrated, medium-power (1- to 3-kW) Mg HET system was developed and tested. Controlled, steady operation at constant voltage and power was demonstrated. Preliminary measurements indicate a specific impulse (Isp) greater than 4,000 s was achieved at a discharge potential of 400 V. The feasibility of delivering fluidized Mg powder to a medium- or high-power thruster also was demonstrated. Phase II of the project evaluated the performance of an integrated, highpower Mg Hall thruster system in a relevant space environment. Researchers improved the medium power thruster system and characterized it in detail. Researchers also designed and built a high-power (8- to 20-kW) Mg HET. A fluidized powder feed system supporting the high-power thruster was built and delivered to Busek Company, Inc.

    In 2D electron systems hosted by crystals with hexagonal symmetry, electron nematic phases with spontaneously broken C3 symmetry are expected to occur in the quantum Hall regime when triplets of Landau levels associated with three different Fermi surface pockets are partially filled. The broken symmetry state is driven by intravalley Coulombic exchange interactions that favor spontaneously polarized valley occupations. I will discuss three different examples of 2D electron systems in which this type of broken symmetry state is expected to occur: i) the SnTe (111) surface, ii) the Bi (111) surface. and iii) unbalanced bilayer graphene. This type of quantum Hall electron nematic state has so far been confirmed only in the Bi (111) case, in which the anisotropic quasiparticle wavefunctions of the broken symmetry state were directly imaged. In the SnTe case the nematic state phase boundary is controlled by a competition between intravalley Coulomb interactions and intervalley scattering processes that increase in relative strength with magnetic field. An in-plane Zeeman field alters the phase diagram by lifting the three-fold Landau level degeneracy, yielding a ground state energy with 2 π/3 periodicity as a function of Zeeman-field orientation angle. I will comment on the possibility of observing similar states in the absence of a magnetic field. Supported by DOE Division of Materials Sciences and Engineering Grant DE-FG03-02ER45958.

  13. The ISOLDE hall

    2002-01-01

    Since 1992, after its move from the 600 MeV SC, ISOLDE is a customer of the Booster (then 1 GeV, now 1.4 GeV). The intense Booster beam (some 3E13 protons per pulse) is directed onto a target, from which a mixture of isotopes emanates. After ionization and electrostatic acceleration to 60 keV, they enter one of the 2 spectrometers (General Purpose Separator: GPS, and High Resolution Separator: HRS) from which the selected ions are directed to the experiments. The photos show: the REX-ISOLDE post accelerator; the mini-ball experiment; an overview of the ISOLDE hall. In the picture (_12) of the hall, the separators are behind the wall. From either of them, beams can be directed into any of the many beamlines towards the experiments, some of which are visible in the foreground. The elevated cubicle at the left is EBIS (Electron Beam Ion Source), which acts as a charge-state multiplier for the REX facility. The ions are further mass analzyzed and passed on to the linac which accelerates them to higher energies. T...

  14. Complying with the Kyoto Protocol under uncertainty: Taxes or tradable permits?

    The Kyoto Protocol allocates tradable emission allowances (AAUs) to developed countries, but they are free to choose a set of policy instruments to comply with these targets. We compare two different policy instruments: a tax and purely domestic tradable permits, for the European Union, the US and Japan. Information on abatement costs and international permit price is imperfect and stems from nine global economic models. For a country party to the Protocol, the benefit of emission reduction is that it can sell more or has to buy less AAUs. We show that in this context, permits entail a slightly lower expected cost than a tax for the US and Japan, whereas both instruments yield an almost equal outcome for Europe. Applying Weitzman's framework (Prices vs. quantities, RES, 1974) in this context, we show the importance of the positive correlation between costs and benefits: technology shocks that lead to low abatement costs in one country generally lead to low abatement costs in other countries too, thereby leading to a low international permit price in the true-up period.

  16. Energy consumption of sport halls

    Energy Technology Data Exchange (ETDEWEB)

    1983-01-01

    The energy consumption of Finland's sports halls (ball games halls, ice hockey halls and swimming halls) represent approximately 1% of that of the country's whole building stock. In the light of the facts revealed by the energy study the potential energy saving rate in sports halls is 15-25%. The total savings would be something like FIM 30-40 million per annum, of which about a half would be achieved without energy-economic investments only by changing utilization habits and by automatic control measures. The energy-economic investments are for the most part connected with ventilation and their repayment period is from one to five years. On the basis of the energy study the following specific consumption are presented as target values: swimming halls: heat (kWh/m*H3/a)100, electricity (kWh/m*H3/a)35, water (l/m*H3/a)1000 icehockey halls (warm): heat (kWh/m*H3/a)25, electricity (kWh/m*H3/a)15, water (l/m*H3/a)200, ball games halls (multi-purpose halls): heat (kWh/m*H3/a)30, electricity (kWh/m*H3/a)25, water (l/m*H3/a)130. In the study the following points proved to be the central areas of energy saving in sports halls: 1. Flexible regulation of the temperature in sports spaces on the basis of the sport in question. 2. The ventilation of swimming halls should be adjusted in such a way that the humidity of the hall air would comply with the limit humidity curve determined by the quality of structures and the temperature of the outdoor air. 3. An ice skating hall is an establishment producing condensing energy from 8 to 9 months a year worth of approx. 100.000-150.000 Finnmarks. The development of the recovery of condensing energy has become more important. 4. The ventilation of ball games halls may account for over 50% of the energy consumption of the whole building. Therefore special attention should be paid to the optimatization of ventilation as a whole.

    We have developed a scanning vector Hall probe microscope for mapping magnetic field vector over magnetic samples. The microscope is based on a micromachined Hall sensor and the cryostat with scanning system. The vector Hall sensor active area is ∼5x5 μm 2 . It is realized by patterning three Hall probes on the tilted faces of GaAs pyramids. Data from these 'tilted' Hall probes are used to reconstruct the full magnetic field vector. The scanning area of the microscope is 5x5 mm 2 , space resolution 2.5 μm, field resolution ∼1 μT Hz -1/2 at temperatures 10-300 K

    1987-01-01

    In this paper some new results concerning magnetohydrodynamic (MHD) equations with the Hall current (HC) term in the Ohm's law are presented. For the cylindrical pinch of a compressible HC fluid, it is found that for large time and long wave length the solution to the governing equations exhibits the behavior of solitons as in the case of an ideal MHD model. In some special cases, the HC model appears to be better posed. An open question is whether a simple toroidal equilibrium of an HC fluid with resistivity and viscosity exists. The answer to this question is affirmative if the prescribed velocity on the boundary has a small norm. Furthermore, the equilibrium is also linearly and nonlinearly stable

  19. Quantum Hall effect

    Joynt, R.J.

    1982-01-01

    A general investigation of the electronic structure of two dimensional systems is undertaken with a view towards understanding the quantum Hall effect. The work is limited to the case of a strong perpendicular magnetic field, with a disordered potential and an externally applied electric field. The electrons are treated as noninteracting. First, the scattering theory of the system is worked out. The surprising result is found that a wavepacket will reform after scattering from an isolated potential. Also it will tend to be accelerated in the neighborhood of the scatterer if the potential has bound states. Fredholm theory can then be used to show that the extended states carry an additional current which compensates for the zero current of the bound states. Together, these give the quantized conductance. The complementary case of a smooth random potential is treated by a path-integral approach which exploits the analogies to the classical equations of motion. The Green's function can be calculated approximately, which gives the general character of both the bound and extended states. Also the ratio of these two types of states can be computed for a given potential. The charge density is uniform in first approximation, and the Hall conductance is quantized. Higher-order corrections for more rapidly fluctuating potential are calculated. The most general conditions under which the conductance is quantized are discussed. Because of the peculiar scattering properties of the system, numerical solution of the Schroedinger equation is of interest, both to confirm the analytical results, and for pedagogical reasons. The stability and convergence problems inherent in the computer solution of the problem are analyzed. Results for some model scattering potentials are presented

    GHG emission in the upstream step of fossil fuel chains could give an environmental as well as economic opportunity for traditional sectors. This study deepens the matter showing an increasing number of initiative over the last few years taken both the involved sectors and by various stake holders (public and private subjects) within the Kyoto flexible mechanism (CDM and JI) or linked to voluntary national or at a global level actions. The above undertakings give evidence for an increased interest and an actual activity dealing with GHG reduction whose results play an evident and positive role for the environment too. Part 1. of this study deals with fossil fuel actions within the Kyoto protocol mechanism. Part 2. will show international and national voluntary initiative [it

    Khanna, N.

    2001-01-01

    This paper examines the cost of meeting the Kyoto Protocol commitments under alternative assumptions regarding technology and technical change. Real GDP is modeled as a function of the capital, labor, and energy inputs. The analysis is based on data for 23 Annex 1 countries from 1965 to 1999. Two important results emerge. First, the standard assumption of Hicks neutral technical change and time and scale independent output elasticities is not supported by the data. Second, when technical change is allowed to be biased in favor of the energy and capital inputs, and when the output elasticities vary with the level of factor use and over time, the loss in real GDP due to the Kyoto commitments rises substantially. On average, the loss in real GDP is one and a half times higher than obtained under the standard assumptions. 26 refs

  2. Research on the reactor physics using the Kyoto University Critical Assembly (KUCA)

    International Nuclear Information System (INIS)

    1986-10-01

    The Kyoto University Critical Assembly [KUCA] is a multi-core type critical assembly established in 1974, as a facility for the joint use study by researchers of all universities in Japan. Thereafter, many reactor physics experiments have been carried out using three cores (A-, B-, and C-cores) in the KUCA. In the A- and B-cores, solid moderator such as polyethylene or graphite is used, whereas light-water is utilized as moderator in the C-core. The A-core has been employed mainly in connection with the Cockcroft-Walton type accelerator installed in the KUCA, to measure (1) the subcriticality by the pulsed neutron technique for the critical safety research and (2) the neutron spectrum by the time-of-flight technique. Recently, a basic study on the tight lattice core has also launched using the A-core. The B-core has been employed for the research on the thorium fuel cycle ever since. The C-core has been employed (1) for the basic studies on the nuclear characteristics of light-water moderated high-flux research reactors, including coupled-cores, and (2) for a research related to reducing enrichment of uranium fuel used in research reactors. The C-core is being utilized in the reactor laboratory course experiment for students of ten universities in Japan. The data base of the KUCA critical experiments is generated so far on the basis of approximately 350 experimental reports accumulated in the KUCA. Besides, the assessed KUCA code system has been established through analyses on the various KUCA experiments. In addition to the KUCA itself, both of them are provided for the joint use study by researchers of all universities in Japan. (author)

    2000-01-01

    The Kyoto Protocol to the United Nations Framework Convention on Climate Change contains quantified, legally binding commitments to limit or reduce greenhouse gas emissions to 1990 levels and allows carbon emissions to be balanced by carbon sinks represented by vegetation. The issue of using vegetation cover as an emission offset raises a debate about the adequacy of current remote sensing systems and data archives to both assess carbon stocks/sinks at 1990 levels, and monitor the current and future global status of those stocks. These concerns and the potential ratification of the Protocol among participating countries is stimulating policy debates and underscoring a need for the exchange of information between the international legal community and the remote sensing community. On October 20-22 1999, two working groups of the International Society for Photogrammetry and Remote Sensing (ISPRS) joined with the University of Michigan (Michigan, USA) to convene discussions on how remote sensing technology could contribute to the information requirements raised by implementation of, and compliance with, the Kyoto Protocol. The meeting originated as a joint effort between the Global Monitoring Working Group and the Radar Applications Working Group in Commission VII of the ISPRS, co-sponsored by the University of Michigan. Tile meeting was attended by representatives from national government agencies and international organizations and academic institutions. Some of the key themes addressed were: (1) legal aspects of transnational remote sensing in the context of the Kyoto Protocol; (2) a review of the current and future and remote sensing technologies that could be applied to the Kyoto Protocol; (3) identification of areas where additional research is needed in order to advance and align remote sensing technology with the requirements and expectations of the Protocol; and 94) the bureaucratic and research management approaches needed to align the remote sensing

  4. Kyoto Protocol Objectives in Croatia Energy Planning: Nuclear Scenario

    International Nuclear Information System (INIS)

    2002-01-01

    Croatia as an Annex I country of the United Nations Framework Convention on Climate Change (UNFCCC) and a country that has pledged in the Annex B of the Kyoto Protocol to reduce its greenhouse gases (GHG) emissions by 5% from the pre-transition level by the budget period 2008-12, will have to envisage a new energy strategy. Compared to the energy consumption collapse in some transitional countries like Russia and Ukraine, Croatia has passed through a relatively limited long term reduction of GHG emissions since 1990 because of higher efficiency of its pre-transition economy. It is expected that in case of business as usual scenario it will breach the Kyoto target in 2003 since the demand for energy will be high, especially as the income continues to rise, particularly in domestic use for heating, for transport and for electricity generation. Several scenarios of developing energy system are compared from the point of view of GHG emissions. The energy sector that will most probably be the most influenced by the UNFCCC objectives is electricity generation. Several scenarios are compared. The cost-effective scenario expects a mixture of coal and gas fired power plants to be built to satisfy the new demand and to replace the old power plants that are being decommissioned. More Kyoto friendly scenario envisages the construction of mostly nuclear power plants in the future, while decommissioning the old ones as planned, and is compared to the others from the GHG emissions point of view. The conclusion is that by measures tackling only electricity generation it will not be possible to keep GHG emission under the Kyoto target level, but that choosing the nuclear option might reduce significantly the cost of compliance.

    Kyoto convention signed in December 1997 will, pending ratification, introduce legal obligations to countries of Annex I of the Convention to reduce CO 2 emission.

Possibility to meet this target without the use of new nuclear facility is doubtful. (author)

    2003-01-01

    We estimate reference CO 2 emission projections in the European Union, and quantify the economic impacts of the Kyoto commitment on Member States. We consider the case where each EU member individually meets a CO 2 emissions target, applying a country-wide cap and trade system to meet the target but without trade among countries. We use a version of the MIT Emissions Prediction and Policy Analysis (EPPA) model, here disaggregated to separately include 9 European Community countries and commercial and household transportation sectors. We compare our results with that of four energy-economic models that have provided detailed analyses of European climate change policy. In the absence of specific additional climate policy measures, the EPPA reference projections of carbon emissions increase by 14% from 1990 levels. The EU-wide target under the Kyoto Protocol to the Framework Convention on Climate Change is a reduction in emissions to 8% below 1990 levels. EPPA emissions projections are similar to other recent modeling results, but there are underlying differences in energy and carbon intensities among the projections. If EU countries were to individually meet the EU allocation of the Community-wide carbon cap specified in the Kyoto Protocol, we find using EPPA that carbon prices vary from $91 in the United Kingdom to $385 in Denmark; welfare costs range from 0.6% to 5%

  10. As if Kyoto mattered: The clean development mechanism and transportation

    2007-01-01

    Transportation is a major source of greenhouse gas (GHG) emissions and the most rapidly growing anthropogenic source. In the future, the developing world will account for the largest share of transport GHG increases. Four basic components drive transportation energy consumption and GHG emissions: activities (A), mode share (S), fuel intensity (I) and fuel choice (F) (ASIF). Currently, the Kyoto Protocol's clean development mechanism (CDM) serves as the main international market-based tool designed to reduce GHG emissions from the developing world. Theoretically, the CDM has the dual purpose of helping developing countries achieve 'sustainable development' goals and industrialized countries meet their Kyoto emissions reduction commitments. This paper reviews overall CDM activities and transportation CDM activities to date and then presents findings from three case studies of transportation CDM possibilities examined with the ASIF framework in Santiago de Chile. The analysis suggests that bus technology switch (I) provides a fairly good project fit for the CDM, while options aimed at inducing mode share (S) to bicycle, or modifying travel demand via land use changes (ASI) face considerable challenges. The implications of the findings for the CDM and the 'post-Kyoto' world are discussed

    2002-06-01

    In this paper we present some numerical simulations with the MacGEM model to evaluate the consequences of the recent Marrakesh agreements and the defection of the USA for the Kyoto Protocol. MacGEM is a global marginal abatement cost model for carbon emissions from fossil fuel use based on the GEM-E3-World general equilibrium. Nonparticipation of the USA causes the equilibrium carbon price in Annex B countries to fall by approximately 50% since an important share of permit demand falls out. Carbon sinks enhancement activities enable Parties to fulfil their reduction commitment at lower compliance costs and cause the equilibrium permit price to decrease by 40%. Finally, it is shown that the former Soviet Union and central European countries have substantial monopoly power in the Kyoto carbon permit market. We conclude that the recent accords have eroded completely the Kyoto Protocol's emission targets but that they have the merit to have saved the international climate change negotiation framework

    A polarized ion source developed under the National Laboratory of High Energy Physics was transferred to the tandem accelerator in Kyoto University at beginning of 1993 to constitute a displacement of incidence into the accelerator. This was an atomic beam type polarized ion source, which is designed to adopt permanent magnets for 6 poles magnet to polarize the electron, to take out atomic nucleus on a shape of positive ion by ECR ionizer after transferring its polarization through transition using radio frequency (RFT), to make it negative ion by charge conversion using alkaline metal vapor, and to put it into the tandem accelerator. Test of the positive ion was finished at the National Laboratory of High Energy Physics, and test in Kyoto University was required after its negative ionization. As the estimated cost was unsufficient and entrance into the ion source facility in the tandem accelerator building was limited in Kyoto University, step of development was slow. Here is reported on present state of the ion source which is now operating stably. (G.K.)

    The Kyoto Protocol, which obliges developed countries to reduce emissions of greenhouse gases (GHG), was adopted at the third session of the conference of the parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Kyoto, Japan, on I I December 1997. Japan subsequently ratified the Kyoto Protocol in 2002 and is required thereunder to reduce GHG emissions by 6% below 1990 levels by 2008-2012. Japan, having already tackled development and promotion of energy conservation technologies after the second oil crisis, emits the lowest level of CO 2 of developed countries approximately 9.4 tons per capita in the year 2000. Consequently, Japan is able to contribute to CO 2 emissions reduction in developing economies as well as in economies in transition by application of Japan's energy conservation technologies. Because the Clean Development Mechanism (CDM) and Joint implementation (JI) of the Kyoto Mechanisms are efficient tools, the Japanese government's policy towards emission reduction makes active use of CDM/JI, thereby supporting domestic efforts in realizing Japan's reduction commitment. The Ministry of Economy, Trade and Industry (METI) of Japan is one of the key ministries to administer Governmental policy making on climate change, and is undertaking establishment of a system to facilitate the Kyoto Mechanisms. The New Energy and Industrial Technology Development Organization (NEDO), under the jurisdiction of METI, supports CDM and JI project activities implemented by Japanese private sector enterprises. In this report, the authors briefly introduce climate change policy measures in Japan and NEDO's activities to promote CDM/Jl. (Author)

    2014-04-01

    The electronic circulator and its close relative the gyrator are invaluable tools for noise management and signal routing in the current generation of low-temperature microwave systems for the implementation of new quantum technologies. The current implementation of these devices using the Faraday effect is satisfactory but requires a bulky structure whose physical dimension is close to the microwave wavelength employed. The Hall effect is an alternative nonreciprocal effect that can also be used to produce desired device functionality. We review earlier efforts to use an Ohmically contacted four-terminal Hall bar, explaining why this approach leads to unacceptably high device loss. We find that capacitive coupling to such a Hall conductor has much greater promise for achieving good circulator and gyrator functionality. We formulate a classical Ohm-Hall analysis for calculating the properties of such a device, and show how this classical theory simplifies remarkably in the limiting case of the Hall angle approaching 90°. In this limit, we find that either a four-terminal or a three-terminal capacitive device can give excellent circulator behavior, with device dimensions far smaller than the ac wavelength. An experiment is proposed to achieve GHz-band gyration in millimeter (and smaller) scale structures employing either semiconductor heterostructure or graphene Hall conductors. An inductively coupled scheme for realizing a Hall gyrator is also analyzed.

    We carry out a thorough study of the topological Hall and topological spin Hall effects in disordered skyrmionic systems: the dimensionless (spin) Hall angles are evaluated across the energy-band structure in the multiprobe Landauer-Büttiker formalism and their link to the effective magnetic field emerging from the real-space topology of the spin texture is highlighted. We discuss these results for an optimal skyrmion size and for various sizes of the sample and find that the adiabatic approximation still holds for large skyrmions as well as for nanoskyrmions. Finally, we test the robustness of the topological signals against disorder strength and show that the topological Hall effect is highly sensitive to momentum scattering.

    Anomalous Hall effect at room temperature in perpendicular Hall balance with a core structure of [Pt/Co]{sub 4}/NiO/[Co/Pt]{sub 4} has been tuned by functional CoO layers, where [Pt/Co]{sub 4} multilayers exhibit perpendicular magnetic anisotropy. A giant Hall resistance ratio up to 69 900% and saturation Hall resistance (R{sub S}{sup P}) up to 2590 mΩ were obtained in CoO/[Pt/Co]{sub 4}/NiO/[Co/Pt]{sub 4}/CoO system, which is 302% and 146% larger than that in the structure without CoO layers, respectively. Transmission electron microscopy shows highly textured [Co/Pt]{sub 4} multilayers and oxide layers with local epitaxial relations, indicating that the crystallographic structure has significant influence on spin dependent transport properties.

  18. The Project Based Mechanisms of the Kyoto Protocol. Credible Instruments or Challenges to the Integrity of the Kyoto Protocol?

    Energy Technology Data Exchange (ETDEWEB)

    Takeuchi Waldegren, Linn

    2006-03-15

    The project based mechanisms of the Kyoto Protocol are innovative instruments which allow projects to earn credits for reducing greenhouse gas (GHG) emissions. The credits can in turn be used by countries to reach their emissions targets according to the Kyoto Protocol. The Project based mechanisms are known as the Clean Development Mechanism (CDM) and the Joint Implementation (JI). If the project based mechanisms are to be effective policy instruments they must ensure the integrity of the Kyoto Protocol, and their ability to promote and prove real emission reductions is critical. The environmental credibility of the project based mechanisms will also ensure their ability to promote cost effectiveness. Key concepts in this context are environmental and project additionality, and their role and value for the project based mechanisms are analyzed. Environmental additionality is established by comparing a project's emissions to a baseline. The baseline's credibility is thus vital. The concept of project additionality is somewhat controversial, but is nonetheless of equal importance. The case studies of CDM approved methodologies (AMs) and proposed projects suggest that there are credibility issues that need to be addressed if the project based mechanisms are to promote real emissions reductions.

    The anomalous Hall effect (AHE) occurs in solids with broken time-reversal symmetry, typically in a ferromagnetic phase, as a consequence of spin-orbit coupling. Experimental and theoretical studies of the AHE are reviewed, focusing on recent developments that have provided a more complete framework for understanding this subtle phenomenon and have, in many instances, replaced controversy by clarity. Synergy between experimental and theoretical works, both playing a crucial role, has been at the heart of these advances. On the theoretical front, the adoption of the Berry-phase concepts has established a link between the AHE and the topological nature of the Hall currents. On the experimental front, new experimental studies of the AHE in transition metals, transition-metal oxides, spinels, pyrochlores, and metallic dilute magnetic semiconductors have established systematic trends. These two developments, in concert with first-principles electronic structure calculations, strongly favor the dominance of an intrinsic Berry-phase-related AHE mechanism in metallic ferromagnets with moderate conductivity. The intrinsic AHE can be expressed in terms of the Berry-phase curvatures and it is therefore an intrinsic quantum-mechanical property of a perfect crystal. An extrinsic mechanism, skew scattering from disorder, tends to dominate the AHE in highly conductive ferromagnets. The full modern semiclassical treatment of the AHE is reviewed which incorporates an anomalous contribution to wave-packet group velocity due to momentum-space Berry curvatures and correctly combines the roles of intrinsic and extrinsic (skew-scattering and side-jump) scattering-related mechanisms. In addition, more rigorous quantum-mechanical treatments based on the Kubo and Keldysh formalisms are reviewed, taking into account multiband effects, and demonstrate the equivalence of all three linear response theories in the metallic regime. Building on results from recent experiment and theory, a

    It is shown that gauge invariance arguments imply the possibility of fractional quantized Hall effect; the Hall conductance is accurately quantized to a rational value. The ground state of a system showing the fractional quantized Hall effect must be degenerate; the non-degenerate ground state can only produce the integral quantized Hall effect. 12 references

    Full Text Available Abstract Sheldon-Hall syndrome (SHS is a rare multiple congenital contracture syndrome characterized by contractures of the distal joints of the limbs, triangular face, downslanting palpebral fissures, small mouth, and high arched palate. Epidemiological data for the prevalence of SHS are not available, but less than 100 cases have been reported in the literature. Other common clinical features of SHS include prominent nasolabial folds, high arched palate, attached earlobes, mild cervical webbing, short stature, severe camptodactyly, ulnar deviation, and vertical talus and/or talipes equinovarus. Typically, the contractures are most severe at birth and non-progressive. SHS is inherited in an autosomal dominant pattern but about half the cases are sporadic. Mutations in either MYH3, TNNI2, or TNNT3 have been found in about 50% of cases. These genes encode proteins of the contractile apparatus of fast twitch skeletal muscle fibers. The diagnosis of SHS is based on clinical criteria. Mutation analysis is useful to distinguish SHS from arthrogryposis syndromes with similar features (e.g. distal arthrogryposis 1 and Freeman-Sheldon syndrome. Prenatal diagnosis by ultrasonography is feasible at 18–24 weeks of gestation. If the family history is positive and the mutation is known in the family, prenatal molecular genetic diagnosis is possible. There is no specific therapy for SHS. However, patients benefit from early intervention with occupational and physical therapy, serial casting, and/or surgery. Life expectancy and cognitive abilities are normal.

    A set of hydrodynamic equations is used to describe quasineutral plasma in ionization and acceleration regions of a Hall thruster. The electron distribution function and Poisson equation are invoked for description of a near-anode region. Numerical solutions suggest that steady-state operation of a Hall thruster can be achieved at different anode sheath regimes. It is shown that the anode sheath depends on the thruster operating conditions, namely the discharge voltage and the mass flow rate

    An extension of Drude model is proposed that accounts for spin and spin-orbit interaction of charge carriers. Spin currents appear due to combined action of the external electric field, crystal field and scattering of charge carriers. The expression for spin Hall conductivity is derived for metals and semiconductors that is independent of the scattering mechanism. In cubic metals, spin Hall conductivity $\\sigma_s$ and charge conductivity $\\sigma_c$ are related through $\\sigma_s = [2 \\pi \\hbar...

    The cylindrical Hall thruster features high ionization efficiency, quiet operation, and ion acceleration in a large volume-to-surface ratio channel with performance comparable with the state-of-the-art annular Hall thrusters. These characteristics were demonstrated in low and medium power ranges. Optimization of miniaturized cylindrical thrusters led to performance improvements in the 50-200W input power range, including plume narrowing, increased thruster efficiency, reliable discharge initiation, and stable operation.

  8. Application of the Kyoto Mechanisms in Finland's climate policy. Report of the Finnish Committee on the Kyoto mechanisms

    2001-01-01

    By the flexible mechanisms under the Kyoto Protocol are meant project-specific Joint Implementation, JI, intended for emissions reduction in the industrialised countries and the Clean Development Mechanism, CDM, designed for emissions reduction in the developing countries. Joint Implementation Projects can be found particularly in the economies-in-transition The flexible mechanisms under the Protocol also include Emissions Trading, ET, which States - and according to the view of several parties, enterprises, too - can conduct subject to rules to be later agreed upon in connection with emissions rights The international climate negotiations on the Kyoto Protocol and on drafting more detailed rules on the use of the mechanisms are still pending. In fact, the Working Group thinks that the uncertainties so far connected with the flexible mechanisms will lead to a situation in which the national climate policy must, at this stage, be primarily based on domestic reduction measures. Even if Finland were prepared to meet her climate policy obligations through domestic measures, there is, in the Working Group's opinion, skill reason to continue the preparations for the possibilities of using the Kyoto flexible mechanisms, too. The prime goal of the flexible mechanisms is an internationally cost-efficient climate policy, which creates the preconditions for the gradual tightening of emission limitations in a manner that will hinder economic and other societal activity as little as possible. Thus the flexible mechanisms can become more important during later commitment periods. According to model calculations, using the mechanisms would probably be inexpensive compared to the domestic emission reduction measures. It seems that the international markets for assigned amount units obtained through the use of the mechanisms would be big enough in view of the relatively limited immediate needs of the Finnish Climate Policy.

    The opening of Judy and Arthur Zankel Hall on 12 September 2003, restores Andrew Carnegie's original 1891 concept of having three outstanding auditoriums of different sizes under one roof, and creates a 21st-century venue for music performance and education. With concerts ranging from early music to avant-garde multimedia productions, from jazz to world music, and from solo recitals to chamber music, Zankel Hall expands the breadth and depth of Carnegie Hall's offerings. It allows for the integration of programming across three halls with minifestivals tailored both to the size and strengths of each hall and to the artists and music to be performed. The new flexible space also provides Carnegie Hall with an education center equipped with advanced communications technology. This paper discusses the unique program planned for this facility and how the architects, theatre consultants, and acousticians developed a design that fulfilled the client's expectations and coordinated the construction of the facility under the floor of the main Isaac Stern Auditorium without having to cancel a single performance.

    The United Nations Framework Convention on Climate Change (UNFCCC) was approved in 1992 to respond to the worl-wide concern about the warming of the planet. The primary target was the stabilization of the concentration of greenhouse gases in the atmosphere, in an attempt to reduce to the minimum the degradation of the environment caused by humans. By virtue of the Convention, the Parts2 are committed to reach their objectives in the reduction of the emissions. A Conference of the Parts was stablished to promote the effective application of the Convention. The third Conference of the Parts, celebrated in Kyoto (Japan, 1997) approved, by consensus, the denominated Kyoto Protocol, in which 39 developed countries and countries with economies in transition were committed to reduce their emissions of greenhouse gases between years 2008 and 2012 in a 5.2 global percent with respect to the 1990 levels. Three {sup f}lexibility mechanisms{sup w}ere stablished to help the Parts to reach their objectives: the emissions trading, the clean development mechanism and the joint implementation.

    Iodine enables dramatic mass and cost savings for lunar and Mars cargo missions, including Earth escape and near-Earth space maneuvers. The demonstrated throttling ability of iodine is important for a singular thruster that might be called upon to propel a spacecraft from Earth to Mars or Venus. The ability to throttle efficiently is even more important for missions beyond Mars. In the Phase I project, Busek Company, Inc., tested an existing Hall thruster, the BHT-8000, on iodine propellant. The thruster was fed by a high-flow iodine feed system and supported by an existing Busek hollow cathode flowing xenon gas. The Phase I propellant feed system was evolved from a previously demonstrated laboratory feed system. Throttling of the thruster between 2 and 11 kW at 200 to 600 V was demonstrated. Testing showed that the efficiency of iodine fueled BHT-8000 is the same as with xenon, with iodine delivering a slightly higher thrust-to-power (T/P) ratio. In Phase II, a complete iodine-fueled system was developed, including the thruster, hollow cathode, and iodine propellant feed system. The nominal power of the Phase II system is 8 kW; however, it can be deeply throttled as well as clustered to much higher power levels. The technology also can be scaled to greater than 100 kW per thruster to support megawatt-class missions. The target thruster efficiency for the full-scale system is 65 percent at high specific impulse (Isp) (approximately 3,000 s) and 60 percent at high thrust (Isp approximately 2,000 s).

    The third Conference of the Parties in Kyoto set the target of reducing greenhouse-gas emissions by an average of 5.3 per cent with respect to 1990 values by 2008 - 2012. One of the main objections to the protocol's ratification is that compliance would pose an unbearable economic burden on the countries involved. But we show here that this is not the case if costs apart from the direct costs of energy production are also considered. Costs are also incurred in rectifying damage to human health, material goods, agriculture and the environment related to greenhouse-gas emissions. (author)

    This paper outlined the 4 proposed policy options to implement the Kyoto Protocol in Canada and presented reasons why the Canadian timetable to ratify the Kyoto Protocol is an unrealistic and unsound policy. The Canadian Prime Minister will ask Parliament to ratify the agreement before the end of 2002 but the authors claim that before any decision regarding ratification is made, the government should cost out all relevant options, under all reasonable contingencies. For policy purposes, this paper focuses on reductions of carbon dioxide. Canada's obligation is to reduce them 6 per cent below 1990 levels by 2010, but because of economic growth, emissions among participating countries may be 30 per cent above their aggregate target. In addition, the withdrawal of the United States means that about two-thirds of the world's emissions are not covered by Kyoto. The first policy option involves the selling of emission permits covering about 80 per cent of domestic emitters. It results in 16 MT of domestic emissions reductions being accomplished and 128 MT of foreign permits being purchased. This first option is considered to be the least costly of the four. The second option relies on command-and-control measures in which 104 MT worth of new targeted measures are forced through. Although the government has not provided cost estimates for option 2, it is likely to be much more costly than option 1. The third option slightly adjusts the mix of permits trading and command-and-control measures, and distributes the permits freely instead of selling them. Only the large emitters are involved in the trading system, covering 40 per cent of domestic emission sources. The cost of emissions reductions would be lower than under option 1. The fourth and final option combines tradable permits systems in which only large emitters are involved, but where permits are distributed according to sectoral emission reduction costs, expected future emission growth rates as well as economic

    The Kyoto Protocol of the United Nations Framework Convention on Climate change, dated December 10, 1997 committed Canada to reduce greenhouse gases to 6% below 1990 levels by 2008-2012. Other nations also committed to varying degrees of reduction. The Protocol includes provisions for credit to the 'developed' counties for initiatives which lead to greenhouse gas reduction in the 'developing' countries and for the sharing of credit between 'developed' countries for projects undertaken jointly. The rules and details for implementation of these guidelines remain to be negotiated. We begin our study by establishing the magnitude of greenhouse gas emissions already avoided by the nuclear industry in Canada since the inception of commercial power plants in 1971. We then review projections of energy use in Canada and anticipated increase in electricity use up to the year 2020. These studies have anticipated no (or have 'not permitted') further development of nuclear electricity production in spite of the clear benefit with respect to greenhouse gas emission. The studies also predict a relatively small growth of electricity use. In fact the projections indicate a reversal of a trend toward increased per capita electricity use which is contrary to observations of electricity usage in national economies as they develop. We then provide estimates of the magnitude of greenhouse gas reduction which would result from replacing the projected increase in fossil fuel electricity by nuclear generation through the building of more plants and/or making better use of existing installations. This is followed by an estimate of additional nuclear capacity needed to avoid CO 2 emissions while providing the electricity needed should per capita usage remain constant. Canada's greenhouse gas reduction goal is a small fraction of international commitments. The Kyoto agreement's 'flexibility mechanism' provisions provide some expectation that Canada could obtain some credit for greenhouse gas

    2004-01-01

    In this paper we evaluate the compliance mechanisms in the Kyoto Protocol as agreed at the seventh Conference of Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Marrakech. We differ from the literature since we concentrate on the complete set of compliance rules agreed in Marrakech and, as a new element, we systematically discuss these compliance incentives in conjunction with the implicit compliance incentives: reputation protection, emission trading and banking. We conclude that effectiveness and efficiency go hand in hand for all explicit and implicit compliance incentives except one--emission trading. Trading improves efficiency but this can also occur at the cost of increasing non-compliance

  20. Global property rights. The Kyoto protocol and the knowledge revolution

    International Nuclear Information System (INIS)

    Chichilnisky, G.

    2006-01-01

    This paper is about the origin of today's global environmental problems, and how to resolve them. At stake are catastrophic risks from global warming and damage to the world's biodiversity that ranks as the planet' sixth great extinction. The origin of today's global environmental problems is a historic difference in property rights regimes between industrial and developing countries, the North and the South. The solutions we suggest involve redefining property rights in the use of the global environment as well as in knowledge. We discuss the Kyoto Protocol's new systems of property rights on the use of the planet's atmosphere, and propose a parallel system of property rights on knowledge. Resources such as forests and oil and other mineral deposits are owned as private property in industrial countries but they are treated as common or government property in developing countries. Ill-defined protected property rights lead to the over-extraction of resources in the South, such as timber and oil. They are exported at low prices to the North that over-consumes them. The international market amplifies the tragedy of the commons, leading to inferior solutions for the world economy as a whole (Chichilnisky 1994). Updating property rights on resources in developing countries would face formidable opposition. The lack of property rights in inputs to production, such as timber and oil, could be compensated by assigning property rights on by-products of outputs. The 1997 Kyoto Protocol provides an example as it limits the countries' rights to emit carbon, a by-product of burning fossil fuels. Our suggestions for trading emissions rights (Chichilnisky 1995, 96) was adopted in the Kyoto Protocol, yet the atmosphere's carbon concentration is a global public good, which makes trading tricky. Trading rights to forests' carbon sequestration services or to genetic blueprints would also be trading global public goods. Markets that trade public goods have been shown to require a

    A database of research publication was constructed for the purpose of grasping all of the research activities at the Research Reactor Institute, Kyoto University. The database named KURRIP collects all of the research publications of the Institute by not only its own staff but also visiting scientists. The publications are in the form of original papers, review papers, papers in proceedings, short notes and letters, synopses over 3 pages presented orally at scientific meeting, books and doctoral theses. At present, the KURRIP database contains the information on 6,210 items which have been published for 30 years since the Institute was established as an interuniversity research institute for joint use of a research reactor and other related large facilities in 1963. By utilizing the KURRIP database, the analyses have been done: (1) affiliation of the authors, (2) kind of publications, (3) classification of publishers, (4) research fields, and (5) experimental facilities. The KURRIP database is now stored in the Data Processing Center of Kyoto University and can be utilized through a computer center at one of the main national universities in Japan. (author)

    Quantum Hall array resistance standards (QHARSs) are integrated circuits composed of interconnected quantum Hall effect elements that allow the realization of virtually arbitrary resistance values. In recent years, techniques were presented to efficiently design QHARS networks. An open problem is that of the evaluation of the accuracy of a QHARS, which is affected by contact and wire resistances. In this work, we present a general and systematic procedure for the error modelling of QHARSs, which is based on modern circuit analysis techniques and Monte Carlo evaluation of the uncertainty. As a practical example, this method of analysis is applied to the characterization of a 1 MΩ QHARS developed by the National Metrology Institute of Japan. Software tools are provided to apply the procedure to other arrays.

This meeting was held as a joint-meeting of KUR's specialist meeting and Tokyo University's activity supported by the Grant-in-Aid for Scientific Research of Ministry of Education, Sport and Culture of Japan. This paper describes the overview of the discussions of this joint-meeting, and interprets their significance. Major themes discussed are, needed discussions on the transmutation research, policy and concepts of the organizations doing transmutation researches, a view from university side, transmutation researches in the oversea countries, opinions from various standpoints of the nuclear fuel cycle, conclusive discussions. 'the meanings of the transmutation research should be discussed together with the geological disposal and fast reactor system', 'transmutation may be a cooperative option for the disposal, thus, they should not be in a independent relation', and Balance evaluation will be needed' are the examples of the conclusive remarks of this meeting.

    In 1926 Dr. Arakatsu was appointed Professor to Taipei Imperial University in Taiwan which was under the government by Japan in that time, and stared the construction of an electrostatic accelerator in 1930 for nuclear transmutations. He measured the detailed branching ratio of deuteron-lithium reaction following the investigation by Lawrence and Rutherford. In 1936 he was transferred to the physics laboratory of Kyoto University, and constructed a 600kV accelerator of Cockcroft-Walton type. His team studied photo-nuclear reactions using gamma rays produced by the proton-lithium reaction. In 1942 he started on the construction of a cyclotron, which was taken away by US army after the war. He participated in the investigation of the atomic bomb to Hiroshima. (K.Y.)

  5. The Potential of the Market for the Kyoto Mechanisms

    Zhang, Z.X.

    2000-01-01

    The Kyoto Protocol is the first international environmental agreement to set legally binding greenhouse gas (GHG) emissions targets and timetables for Annex I countries. It incorporates emissions trading and two project-based flexibility mechanisms, namely joint implementation (JI) and the clean development mechanism (CDM) to help Annex I countries to meet their Kyoto targets at a lower overall cost. The extent to which their compliance cost can be lowered depends on the size of the market for all three flexibility mechanisms under the Protocol. This article estimates the size of such a market and demonstrates that restrictions on the use of flexibility mechanisms not only reduce potential of the Annex I countries' efficiency gains, but are furthermore not beneficial to developing countries since they restrict the total financial flows to developing countries under the CDM. Thus, from the perspective of husbanding the world's limited resources, the fewer the restrictions on the use of flexibility mechanisms, the greater are the gains from their use

    1998-05-01

    An American industry perspective of the Kyoto Protocol and its ability to produce a viable solution to global warming was offered. The Protocol would require most industrialized nations (including Canada and the United States) to cut their carbon dioxide emissions by 6 to 8 per cent below 1990 levels by year 2008 to 2012. Developing countries would not have to meet this target. It was argued that this set of targets and timetables assumes that climate risks are known with great certainty, when in fact, the long term risks of climate change are highly uncertain and near-term risks are small. It was also argued that developing countries account for more than half of the growth in CO{sub 2} emissions, therefore, their exemption from the Kyoto Protocol would make the Protocol ineffective against even a moderate warming scenario. Furthermore, the Protocol has the potential to create reactionary incentives for energy-intensive industries to move their facilities and jobs to countries without the curbs on CO{sub 2} emissions. It was suggested that a better climate policy would include all countries in CO{sub 2} reductions. It would be less expensive to achieve a target CO{sub 2} atmospheric concentration by curbing emissions slowly at first, developing technology to do so more cheaply and moving more aggressively in later years. The reality is that if the climate policy is too expensive, it is less practical and more difficult to achieve, both economically and politically. 1 tab., 2 figs.

    1998-01-01

    The compatibility of the Kyoto Protocol flexible instruments and the lessons that can be learned form the AIJ-phase (AIJ stands for Activities Implemented Jointly) are discussed. The key point to be made is that there may be various applications of flexible instruments which can create situations where the various instruments would crowd out each other. On the other hand, applying flexible instruments may create a leverage for Parties in terms of achieving domestic environmental objectives. In addition, several issues related to the implementation of Joint Implementation (JI) , Clean Development Mechanism (CDM) and international emissions trading are discussed. The issues concern mainly those that have been included in the working programme on flexible instruments for CoP4 and CoP5 (CoP stands for Convention of Parties). As such the report discusses the consequences of possible negotiations outcomes at CoP for the effectiveness of flexible instruments, Parties' capabilities to achieve their Kyoto Protocol commitments cost-effectively, and the role of the private sector on the national and international credits markets(s). 106 refs

The report begins by defining the term Environmental Agreement (EA) and then explores EAs in three steps: (1) Advantages and disadvantages of EAs compared to other policy tools (direct regulation, taxes and tradable permits), based on theoretical studies and experience from practical use, (2) The potential of EAs as an international policy tool, either in a bilateral or regional setting, (3) The attractiveness of EAs to implement the Kyoto Protocol, and the relation to joint implementation and international emissions trading. The main conclusions are: (1) Experience from OECD countries suggests that EAs are most attractive as a supplement to traditional command and control, or to market-based policy tools. (2) Skillful design of EAs can improve their efficiency. (3) Bilateral EAs is an interesting policy option to regulate pollution from other countries. (4) Regional EAs are rare but could have important advantages. (5) EAs can play a role in a soft transition stage from traditional command and control to domestic emission trading, and further on to a Kyoto Protocol regime of emission trading and joint implementation. 52 refs., 2 figs., 2 tabs.

    The Kyoto Protocol has laid the basis of global markets for greenhouse gas emission reductions. By means of the Kyoto Mechanisms Joint Implementation, the Clean Development Mechanism and International Emissions Trading it will be possible to produce abroad and trade internationally the greenhouse gas emission reductions needed to satisfy cost-efficiently the respective demand of industrialized countries. The paper analyses options available in the natural gas sector for realizing Joint Implementation and Clean Development Mechanism projects. Furthermore, it examines strategies that might be economically viable for companies operating in the natural gas sector for taking advantage of the Kyoto Mechanisms. (author)

  10. ac spin-Hall effect

    Full Text:The spin-Hall effect is described. The Rashba and Dresselhaus spin-orbit interactions are both shown to yield the low temperature spin-Hall effect for strongly localized electrons coupled to phonons. A frequency-dependent electric field E(ω) generates a spin-polarization current, normal to E, due to interference of hopping paths. At zero temperature the corresponding spin-Hall conductivity is real and is proportional to ω 2 . At non-zero temperatures the coupling to the phonons yields an imaginary term proportional to ω. The interference also yields persistent spin currents at thermal equilibrium, at E = 0. The contributions from the Dresselhaus and Rashba interactions to the interference oppose each other

    The majority of climate protection experts believe that the Kyoto Protocol in its present version provides a basis for preventing the climate change from taking on disastrous dimensions. In the meantime however a mainstream of opinion has developed which advocates the establishment of a functioning global climate protection system for the post-Kyoto phase. Kyoto Plus, a global climate certification system, is a concept developed by the author of three expert opinions for the state of Baden-Wuerttemberg which takes the principles of the Kyoto Protocol a step forward while striving to eliminate its weaknesses and which has matured sufficiently to be put into practice. Systems of this or a similar kind could enable Germany to make a decisive additional contribution to global climate protection, as the author stated at the BT Hearing on 23 May 2007.

    The Kyoto Protocol to the Framework Convention on Climate Change (FCCC) was completed on the morning of December 11, 1997, following over two years of negotiations. The product of these deliberations is a complex and incomplete document knitting together the diversity of interests and perspectives represented by the more than 150 delegations. Because the document is complex, its implications are not immediately obvious. If it enters into force, the Kyoto Protocol will have far-reaching implications for all nations--both nations with obligations under the Protocol and those without obligations. National energy systems, and the world's energy system, could be forever changed. In this paper the authors develop an assessment of the energy and economic implications of achieving the goals of the Kyoto Protocol. They find that many of the details of the Protocol that remain to be worked out introduce critical uncertainties affecting the cost of compliance. There are also a variety of uncertainties that further complicate the analysis. These include future non-CO{sub 2} greenhouse gas emissions and the cost of their mitigation. Other uncertainties include the resolution of negotiations to establish rules for determining and allocating land-use emissions rights, mechanisms for Annex 1 trading, and participation by non-Annex 1 members in the Clean Development Mechanism. In addition, there are economic uncertainties, such as the behavior of Eastern Europe and the former Soviet Union in supplying emissions credits under Annex 1 trading. These uncertainties in turn could affect private sector investments in anticipation of the Protocol's entrance into force. The longer the nature of future obligations remains unclear, the less able decision makers will be to incorporate these rules into their investment decisions. They find that the cost of implementing the Protocol in the US can vary by more than an order of magnitude. The marginal cost could be as low as $26 per

    Coming into force of Kyoto Protocol (KP) in February 2005, as a result of its signing by Russian Federation, created the lawfulness of its provisions and mechanisms in order to reduce the average emission of Greenhouse Gases (GHG) at a global level down to 5.2 %. Passing this environment problem from a constrained area (regulations, directives) to an opportunity area (business) created the possibility that the achievement of KP objectives to be not an exclusive financial task of 'polluting actors', but opened the opportunity of bringing on stage all the necessary elements of a modern business environment: banks, investments from founds companies, consultants, buyers, sellers, stocks exchange. Until now, the investments and emissions transactions based by KP mechanisms at the worldwide level was focused on renewable energy area. Because for the most of countries, including Romania, the production of electricity based on fossil fuels (special coal) is one of the main option, bringing the KP mechanisms in operation in this area is difficult for at least two reasons: - the investments are huge; - the emissions reduction is not spectacular. In these circumstances, this paper gives an overview of the present GHG emission market, transaction mechanisms on this market and of the ways through which coal based electricity producers from Romania can access this market. We consider that the filtration of the information in this area from electricity producer point of view makes the content of this paper a good start for a new approach of environment management and its conversion from constraint (financial resources consumer) to opportunity ( financial resources producer). The paper contains are as follows: 1. Kyoto Protocol at a glance; 2. Emission trading mechanisms; 2.1. Transaction mechanisms under KP; 2.1.1. Joint Implementation (JI); 2.1.2 Clean Development Mechanism (CDM); 2.1.3. Emissions Trading (ET); 2.2. Other transactions mechanisms; 2.2.1. European Union Emissions

    Human Resource Development was the first and remains an important pillar in Japanese foreign aid. I will argue that Japan has access to a global network of alumni who will co-define Japanese foreign aid in the future, because Japan has encouraged alumni societies and networking since 1965. A total...... of more than a million people in more than 100 countries have attended courses in Japan funded fully or partly by Japanese ODA since the inception of the technical assistance programs in 1954 through the Colombo Plan and since 1959 through the Association of Overseas Technical Scholarships (AOTS from 2009...... HIDA). Many of these alumni have and will in the future exchange ideas and keep contact not only to Japan, but also to fellow alumni around the globe and, thereby, practice south-south exchanges, which are made possible and traceable by their established alumni network and the World Network of Friends...

    A new materials irradiation facility with improved control capabilities has been installed at the Kyoto University Reactor (KUR). Several deficiencies of conventional fission neutron material irradiation systems have been corrected. The specimen temperature is controlled both by an electric heater and by the helium pressure in the irradiation tube without exposure to neutrons at temperatures different from the design test conditions. The neutron spectrum is varied by the irradiation position. Irradiation dose is changed by pulling the irradiation capsule up and down during irradiation. Several characteristics of the irradiation field were measured. The typical irradiation intensity is 9.4x10 12 n/cm 2 s (>0.1 MeV) and the irradiation temperature of specimens is controllable from 363 to 773 K with a precision of ±2 K

Artigas analiza qué significa en Popper la «fe irracional en la razón» y utiliza, como fuente inédita, el dramático relato que hace Popper de su relación con W. W. Bartley, por primera vez, en Kyoto, en 1992. Sea cual fuere la opinión del lector, el libro de Artigas divide la hermenéutica de Popper en un antes y un después.

    2003-01-01

    We present a model for climate change policy analysis which accounts for the possibility that technology evolves endogenously and that technical change can be induced by environmental policy measures. Both the output production technology and the emission-output ratio depend upon a stock of knowledge, which accumulates through R and D activities. Two versions of this model are studied, one with endogenous technical change but exogenous environmental technical change and the other with both endogenous and induced technical change. A third version also captures technological spillover effects. As an application, the model is simulated allowing for trade of pollution permits as specified in the Kyoto Protocol and assessing the implications in terms of cost efficiency, economic growth and R and D efforts of the three different specifications of technical change

    To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

    Four research reactors are currently licensed for medical application in Japan. As of July 1995, approximately 210 clinical irradiations using these research reactors have been done for brain and skin tumors as shown. The number of chief medical doctors certified by the Government is eleven so far. Among them, eight doctors have already treated tumor patients using the Kyoto University Reactor (KUR, 5MW). Recently in USA clinical trials have been restarted using epithermal neutrons at MIT and BNL. In this paper, the experience of clinical trials of boron neutron capture therapy (BNCT) which have been performed in Japan, mainly physics studies, are reviewed, and current studies are also introduced

  7. Climate Change Taxes and Energy Efficiency in Japan

    International Nuclear Information System (INIS)

    Kasahara, S.; Paltsev, S.; Reilly, J.; Jacoby, H.; Ellerman, A.D.

    2007-01-01

    In 2003 Japan proposed a Climate Change Tax to reduce its CO2 emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan's recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount of the Russian allowance is not available in international markets

    In April this year, the Department of Industry, Science and Resources published a report outlining the dilemmas facing Japan's energy industry in the post-Kyoto environment with particular reference to the effect it would have on Australia's fuel exports. The following article is based on information in that report. In summary, the extent to which the Japanese government's current climate change response policy (the long term energy forecast) is realised will depend on a complex interaction of competing considerations: 1. whether, in the event of US non ratification, the government maintains its Kyoto commitment or opts for a partial step back from its 8% commitment (and the extent of that draw back); 2. in the event that it does maintain its Kyoto commitment: a) the extent to which it takes advantage of the flexible mechanism provisions to ease the abatement burden on the energy system; b) the level of success in securing additional nuclear power stations and higher load ratios from nuclear power; c) the degree to which renewable and recycling energy sources can be brought on line; d) the extent to which the Japanese people are willing to meet the costs of switching to new technology and changing lifestyles to conserve energy; e) the timing of new initiatives such as emissions trading; the extent to which Japanese industry is able to achieve very strict energy conservation targets; f) the extent to which Japan's economic recovery leads to increased electricity demand as well as g) the extent to which electricity deregulation reduces prices and promotes increased consumption

    Fifty-four cases of glucose 6-phosphate dehydrogenase (G6PD) deficiency have so far been reported in Japan. Among them, 21 G6PD variants have been characterized. Nineteen out of the 21 variants were characterized in our laboratory and G6PD Heian and "Kyoto" by others. G6PD Tokyo, Tokushima, Ogikubo, Kurume, Fukushima, Yokohama, Yamaguchi, Wakayama, Akita, Heian and "Kyoto" were classified as Class 1, because all these cases showed chronic hemolytic anemia and severe enzyme deficiency. All these variants showed thermal instability. G6PD Mediterranean-like, Ogori, Gifu and Fukuoka were classified as Class 2, whereas G6PD Hofu, B(-) Chinese, Ube, Konan, Kamiube and Kiwa belonged to Class 3. All the 6 Class 3 variants were found as the results of the screening tests. The incidence of the deficiency in Japanese seems to be 0.1-0.5% but that of the cases which may slow drug-induced hemolysis would be much less. G6PD Ube and Konan appear to be relatively common in Japan.

  12. Nuclear power development in Japan

    International Nuclear Information System (INIS)

    Mishiro, M.

    2000-01-01

    This article describes the advantages of nuclear energy for Japan. In 1997 the composition of the total primary energy supply (TPES) was oil 52.7%, coal 16.5%, nuclear 16.1% and natural gas 10.7%. Nuclear power has a significant role to play in contributing to 3 national interests: i) energy security, ii) economic growth and iii) environmental protection. Energy security is assured because a stable supply of uranium fuel can be reasonably expected in spite of dependence on import from abroad. Economic growth implies the reduction of energy costs. As nuclear power is capital intensive, the power generation cost is less affected by the fuel cost, therefore nuclear power can realize low cost by favoring high capacity utilization factor. Fossil fuels have substantial impacts on environment such as global warming and acid rain by releasing massive quantities of CO 2 , so nuclear power is a major option for meeting the Kyoto limitations. In Japan, in 2010 nuclear power is expected to reach 17% of TPES and 45% of electricity generated. (A.C.)

  13. Hall effect in noncommutative coordinates

    Dayi, Oemer F.; Jellal, Ahmed

    2002-01-01

    We consider electrons in uniform external magnetic and electric fields which move on a plane whose coordinates are noncommuting. Spectrum and eigenfunctions of the related Hamiltonian are obtained. We derive the electric current whose expectation value gives the Hall effect in terms of an effective magnetic field. We present a receipt to find the action which can be utilized in path integrals for noncommuting coordinates. In terms of this action we calculate the related Aharonov-Bohm phase and show that it also yields the same effective magnetic field. When magnetic field is strong enough this phase becomes independent of magnetic field. Measurement of it may give some hints on spatial noncommutativity. The noncommutativity parameter θ can be tuned such that electrons moving in noncommutative coordinates are interpreted as either leading to the fractional quantum Hall effect or composite fermions in the usual coordinates

    The reported vibration data were generated from measurements made on the experimental hall floor on December 2, 1992. At the time of the measurements, the ESRF hydrolevel was set-up in the Early Assembly Area (EAA) of the experimental hall and was being used to measure static displacement (settlement) of the floor. The vibration measurement area was on and adjacent to the EAA, in the vicinity of the ESRF hydrolevel test which was in progress. This report summarizes the objectives, instrumentation, measurement locations, observations, and conclusions, and provides selected results in the form of RMS vs. time plots, and power spectral densities from which frequency information can be derived. Measured response amplitudes were within the vibration criteria established for the APS

    Vickers, P.

    2004-01-01

    This paper reviews uncertainties in the oil sands industry in relation to climate change, greenhouse gas emissions and the Kyoto Protocol. Other issues contributing to uncertainties in the industry were also discussed, including water and natural gas issues, refinery capacity and markets, price and exchange rates as well as capital availability and project cost overruns. The potential economic impact of the Kyoto Protocol on oil sands was outlined with prices per barrel. Government regulations were examined in the context of the evolving expectations of the Canadian public. U.S. actions on climate change were examined at the federal and state level. Emissions trading systems were reviewed with reference to a post 2012 regime. The 2005 budget was discussed, along with the Canadian legislative agenda and domestic offsets program, as well as the regulatory agenda in June of 2005. Post 2012 issues were examined, including discussions on the next commitment period, with reference to the fact that there was no support for new commitments among developing countries but that domestic pressures was building in the U.S. for air and climate regulations. Pressures from shareholders and the scientific community were discussed. Emissions trading in the European Union was reviewed. Stabilization goals will mean significant cuts to emissions in order to accommodate growth. Scenario planning and climate change uncertainties were also reviewed. The benefits of scenario planning in complex situations were outlined and were seen to encourage the development of strategic options. Issues concerning environmental stewardship and possible responses by the Unites States were discussed. Three scenarios were outlined: that climate change is not man-made and all the problems will go away; that technology will evolve to accommodate changes; and that policy will be insensitive to the economy, technology will lag and the energy sector will be faced with much higher costs.

    Full text: The biomass available in Kyoto City located in urban area of Japan was estimated to be 2.02x10 6 t-wet/ yr (0.14x10 6 k liter/ yr oil equivalent), of which waste paper, waste timber, waste food, unused forest wood from the surrounding mountains and sewage sludge account for the largest amounts on an energy basis. These types of biomass can contribute to utilize for the reduction of fossil fuel consumption and for the reduction of greenhouse gas (GHG) emission. Therefore we started the Kyoto-Bio-Cycle Project (FY 2007-2009), which is the demonstration of renewable energy conversion technologies from the biomass. Specifically, we aimed for the greening of necessary materials such as methanol and the cyclic use of byproducts, with the bio diesel fuel production from used cooking oil (5 k liter-methyl ester/ day) as the core activity. Two technologies are being developed as part of the project. One is gasification and methanol synthesis to synthesize methanol with the pyrolytic gas generated from woody biomass. The other is high efficiency bio gasification that treats waste food, waste paper, and waste glycerin. This technology can improve the production rate of biogas and reduce the residue through the introduction of 80 degree Celsius-hyper-thermophilic hydrolysis in the 55 degree Celsius-thermophilic anaerobic fermentation process. These systems can produce 4 types of renewable energy such as bio diesel fuel, biogas, electricity and heat. And we conducted the life-cycle system analysis of GHG reduction effect for the demonstrating technologies, additionally we examined an optimum method of biomass utilization in the future low-carbon-society. As a result, the method that produces the liquid fuel (methanol, Ft oil) from dry biomass (waste timber, etc.) and the biogas from wet biomass (waste food, etc.) can reduce GHG emission highly at present and in the future, compared with the current direct combustion of biomass for the power generation.

    This article analyses the abatement costs of three post-Kyoto regimes for differentiating commitments compatible with stabilising atmospheric greenhouse gases concentrations at 550 ppmv CO 2 equivalent in 2100. The three regimes explored are: (1) the Multi-Stage approach assumes a gradual increase in the number of Parties involved who are adopting either emission intensity or reductions targets; (2) the Brazilian Proposal approach, i.e. the allocation or reductions based on countries' contribution to temperature increase; (3) Contraction and Convergence, with full participation in convergence of per capita emission allowances. In 2050, the global costs increase up to about 1% of the world GDP, ranging from 0.5% to 1.5%, depending on baseline scenario and marginal abatement costs. Four groups of regions can be identified on the basis of similar costs (expressed as the percentage of GDP). These are: (1) OECD regions with average costs; (2) FSU, the Middle East and Latin America with high costs; (3) South-East Asia and East Asia (incl. China) with low costs; and (4) South Asia (incl. India) and Africa with net gains from emissions trading for most regimes. The Brazilian Proposal approach gives the highest costs for groups 1 and 2. The distribution of costs for the Contraction and Convergence approach highly depends on the convergence year. The Multi-Stage approach and Contraction and Convergence (convergence year 2050) seem to result in relatively the most even distribution of costs amongst all Parties

    Two Van de Graaff accelerators are available at the Uji campus of Kyoto University. One is a 4MV machine, which is used for heavy ion acceleration, while the other is a 2MV machine for electron acceleration. These machines have been modified in various parts and currently used very actively in many fields of investigation. Important modifications of the 4MV machine are: use of a newly developed accelerating tube, addition of a charge-changer before the analyzing magnet, renewal of the charging belt, and development of a microbeam system for PIXE and RBS analysis. An attempt is now being made to accelerate micro-particles using the 2MV machine. The new accelerating tube has bucket type electrodes with large accelerating apertures. By charge-changing the accelerated 1+ ions to higher charge states, 2+, 3+, ..., at the entrance of the analyzing magnet, Ar ions with energies of up to 2.73, 6.21, .... MeV can be deflected to the duct. Scanning microbeam PIXE and RBS are powerful tools for analysis of spatial elemental distribution. Calculations suggest that a beam size of about 3 μm can be attained by using an object aperture of 10μm in diameter and controlling the beam divergence within 10μ rad in both directions. (N.K.)

    Construction of a 433 MHz, 7 MeV proton linear accelerator is currently underway in Kyoto University under a three-year plan starting in 1986. The ion source, power source for it, RFQ main unit, WR2100 waveguide and a set of klystrons for RFQ were installed last year, or the first year of the plan, and the power source for the klystrons for RFQ, a set of klystrons for STL, DTL main unit, etc., are planned to be installed this year. Operation has not started yet because of the absence of the power source for the klystrons. Thus this report is focused on the considerations made in selecting the acceleration frequency of 433 MHz, specifications of the klystrons and the structure of the power sources for them. Based on considerations of the efficiency and cost of the accelerating tubes and RF sources to be used, the acceleration frequencies of 433.33 MHz and 1,300 MHz were adopted. The klystron selected is Litton L5773, which has a peak power output of 1.25 Mw, average power output of 75 kW, maximum pulse width of 2,000 μS and duty of 6 percent, and it consists of four cavities. The structure and characteristics of a klystron are also described. (Nogami, K.)

    The obligations resulting from the Kyoto Protocol (KP) are implemented by many participants, e.g. Greece, by a combination of two methods: (a) application of regional measures which restrict CO 2 emissions and (b) procurement of green certificates e.g. in a Climate Exchange Market (CEX). Therefore, the cost for compliance with the KP depends on the extent each method is used and also on the traded values in the CEX. The energy policy and planning to be considered are long-term items and now extension of the KP to a post-KP is discussed which reaches year 2020. In Greece, the electricity sector is with a weighted CO 2 contribution of 73%, the dominantly emission sector. The paper analyzes the cost and other merits of different scenarios for the expansion of electrical power system in Greece. For different scenarios, the total cost of the electrical power system expansion is calculated as a function of the price of emission certificates. It has been shown that there is a price of 27.5 Euro /tCO 2 , above which specific mitigation measures may lead to cost optimum solutions. A sensitivity analysis is also presented concerning the variation of key parameters like the participation in the system expansion of new supercritical coal units, the price evolution of natural gas, the RES usage rate and the discount rates of the expansion investments. Results may be of interest for a decision on the cost optimum electrical power system expansion

    Recent important experience in improving the operational safety and life of a reactor are described. The Kyoto University Reactor (KUR) is a 25-year-old 5 MW light water reactor provided with two thermal columns of graphite and heavy water as well as other kinds of experimental facilities. In the graphite thermal column, noticeable amounts of neutron irradiation effects had accumulated in the graphite blocks near the core. Before the possible release of the stored energy, all the graphite blocks in the column were successfully replaced with new blocks using the opportunity provided by the installation of a liquid deuterium cold neutron source in the column. At the same time, special seal mechanisms were provided for essential improvements to the problem of radioactive argon production in the column. In the heavy-water thermal column we have accomplished the successful repair of a slow leak of heavy water through a thin instrumentation tube failure. The repair work included the removal and reconstructions of the lead and graphite shielding layers and welding of the instrumentation tube under radiation fields. Several mechanical components in the reactor cooling system were also exchanged for new components with improved designs and materials. On-line data logging of almost all instrumentation signals is continuously performed with a high speed data analysis system to diagnose operational conditions of the reactor. Furthermore, through detailed investigations on critical components, operational safety during further extended reactor life will be supported by well scheduled maintenance programs

    In the Kyoto Protocol, all Annex I countries have agreed to reduce their carbon dioxide emissions with a certain percentage in 2008-2012 compared to 1990. To achieve that target, some direct human induced activities initiated in the Land-use Change and Forestry sector since 1990, may be used. However, the wording in the Protocol has caused confusion on what is exactly meant in the Protocol, which activities may be included, whether soils should be included and whether any additional measures may be included in the future. Also, the way of monitoring, verification and reporting is unclear. In this NRP project the implications of a choice for a certain definition, additional compartments of the C cycle, and feasibility of monitoring are assessed for a limited number of countries. This is done by applying those definitions and additional measures to the countries` C budget on the latest data. The forest related matters are handled by the Institute for Forestry and Nature Research (IBN-DLO), the soil related matters are handled by the Research Institute for Agrobiology and Soil fertility (AB-DLO), the monitoring and verification matters are handled by the Winand Staring Centre for Integrated Land, Soil and Water Research (SC-DLO). 120 refs.

    The current climate change commitments and the negotiating positions of Annex I countries were discussed. It was pointed out that the energy sector is not homogeneous and therefore, climate change should focus on the areas all over the world which are most sensitive to a carbon value. It was also noted that while the present time is ripe for action on climate change, actions should not take place at any cost. A scenario based on the three principal functions of energy, i.e. to supply mobility, electricity and heat was proposed. It was claimed that this proposal had the potential to bridge the gap between the political reality of Kyoto and the economic realities of the energy sector. The essence of the proposal centred around the concept of 'carbon value'. The effect of establishing carbon values for each of the different energy services worldwide, was discussed. Various mechanisms for establishing carbon values, such as emission trading, joint implementation with non-Annex I parties, penalties for non-compliance, mitigation efforts in least-cost options, were also reviewed

    The results from the first commitment period of the Kyoto Protocol (KP) show that developed countries fulfilled their commitments through varied strategies. However, the Kyoto protocol did not manage to stabilize global GHG concentrations; furthermore its direct impact on domestic emissions reductions is unclear. Nevertheless, the KP has likely paved the way for a low-carbon transition by establishing international standards on emissions monitoring and on emission reductions projects. Yet, domestic policies - especially the EU ETS - are the main driver of emissions reductions and the principal catalyzers of private finance flows. A new, more effective, agreement would therefore need to expand its coverage, and take down the specter of 'internationally binding' emission reductions commitments in order to focus on MRV requirements. Similar to Kyoto, a Paris outcome could take the form of a framework agreement setting up requirements and mechanisms with subsequent implementing agreements expected by 2020. (authors)

    Healthcare reform as part of the economic recovery plan in Japan is placing emphasis on the use of healthcare information technology (HIT). This research mainly focuses on the HIT efforts in Japan with reference to the US for context. The purpose is to: (a) provide detail on governmental policy impacting promotion of HIT adoption to provide services to the people of Japan, (b) describe the outcomes of past and present policy impacting progress based on a case study of HIT use in the Kyoto Yamashina area, and (c) discuss issues for refinement of current policy. The method is case study, and data collection techniques include: (a) interviews of people involved in policy making for HIT in Japan (Japanese healthcare professionals, government officials, and academics involved in HIT research in Japan) and use in the medical community of HIT in the Kyoto Yamashina area, (b) archived document analysis of reports regarding government policy for HIT policy and user assessment for HIT mainly in the case study site, and (c) the literature review about HIT progression and effectiveness assessments to explore and describe issues concerning the transformation with HIT in Japan. This study reveals the aspects of governmental policy that have been effective in promoting successful HIT initiatives as well as some that have been detriments in Japan to help solve pressing social issues regarding healthcare delivery. For example, Japan has stipulated some standardized protocols and formats for HIT but does not mandate exactly how to engage in inter-organizational or intra-organizational health information exchange. This provides some desired autonomy for healthcare organizations and or governments in medical communities and allows for more advanced organizations to leverage current resources while providing a basis for lesser equipped organizations to use in planning the initiative. The insights gained from the Kyoto Yamashina area initiative reflect the success of past governmental

  11. Spin Hall effect by surface roughness

    KAUST Repository

    Zhou, Lingjun

    2015-01-08

    The spin Hall and its inverse effects, driven by the spin orbit interaction, provide an interconversion mechanism between spin and charge currents. Since the spin Hall effect generates and manipulates spin current electrically, to achieve a large effect is becoming an important topic in both academia and industries. So far, materials with heavy elements carrying a strong spin orbit interaction, provide the only option. We propose here a new mechanism, using the surface roughness in ultrathin films, to enhance the spin Hall effect without heavy elements. Our analysis based on Cu and Al thin films suggests that surface roughness is capable of driving a spin Hall angle that is comparable to that in bulk Au. We also demonstrate that the spin Hall effect induced by surface roughness subscribes only to the side-jump contribution but not the skew scattering. The paradigm proposed in this paper provides the second, not if only, alternative to generate a sizable spin Hall effect.

  12. Tunneling Anomalous and Spin Hall Effects.

    We predict, theoretically, the existence of the anomalous Hall effect when a tunneling current flows through a tunnel junction in which only one of the electrodes is magnetic. The interfacial spin-orbit coupling present in the barrier region induces a spin-dependent momentum filtering in the directions perpendicular to the tunneling current, resulting in a skew tunneling even in the absence of impurities. This produces an anomalous Hall conductance and spin Hall currents in the nonmagnetic electrode when a bias voltage is applied across the tunneling heterojunction. If the barrier is composed of a noncentrosymmetric material, the anomalous Hall conductance and spin Hall currents become anisotropic with respect to both the magnetization and crystallographic directions, allowing us to separate this interfacial phenomenon from the bulk anomalous and spin Hall contributions. The proposed effect should be useful for proving and quantifying the interfacial spin-orbit fields in metallic and metal-semiconductor systems.

    To be ready for the computing-everywhere age to come, it is necessary to create environments in which the barrier-free utilization is ensured of various apparatuses of the daily routine, such as various bodily function substituting apparatuses capable of compensating for the degraded functions of disabled or aged individuals. Under the circumstances, a system for building man-machine interfaces in the home or the like is required, and fundamental technologies of architecture and information infrastructure have to be established on which the development of technologies for the field involved will proceed. Concerning the technologies already in existence in this field of research, a survey is conducted of the status of research and development of information interface techniques primarily at Stanford University, and a report is made thereon. Also reported is the information obtained at Technology and Persons with Disabilities Conference 1999. The result of a survey of the trend of research and development of the smart house under the TIDE (Technology Initiative for Disabled and Elderly People) project and the result of a survey of an information standardization project for equipment control in Europe are reported, and the result of a survey of the approach of Kyoto's welfare apparatus distributors to the development of equipment is made known.

    Outdoor advertisements must be one of the major factors that affect our psychological impression for townscapes. They often conflict with propr color environments in cities particularly in historic cities like Kyoto. In this study we investigated how outdoor advertisements influenced our visual evaluation of townscapes in Kyoto. In recent years, a new regulation for outdoor advertisements came into operation in Kyoto and some of the advertisements have been replaced or removed gradually. We examined psychological evaluation for the townscapes before and after their changes. In the experiment, subjects evaluated 'visual harmony,' 'visual busyness,' 'visual comfort' and 'suitability to Kyoto' of townscapes projected on a screen. The results indicated that the evaluation of 'visual busyness' significantly decreased with the amount of the advertisements. The relations between the advertisements and the psychological evaluation of the townscape are discussed.

    We report experimental investigations on the quantum phase transition between the two opposite Hall plateaus of a quantum anomalous Hall insulator. We observe a well-defined plateau with zero Hall conductivity over a range of magnetic field around coercivity when the magnetization reverses. The features of the zero Hall plateau are shown to be closely related to that of the quantum anomalous Hall effect, but its temperature evolution exhibits a significant difference from the network model for a conventional quantum Hall plateau transition. We propose that the chiral edge states residing at the magnetic domain boundaries, which are unique to a quantum anomalous Hall insulator, are responsible for the novel features of the zero Hall plateau.

    This third meeting of the Parties to the UN Framework Convention on Climate Change, held from 1-10 December 1997 in Kyoto/Japan, on which high expectations had been placed, just as on the Berlin meeting two years ago, has certainly not come up to expectations, but still agreed upon a Protocol that can be called an important signpost in international policy for protection of the environment. The envisaged greenhouse gas reduction by 5.2 per cent (of 1990 emissions) laid down in the Protocol, to be achieved by the industrialized countries either individually or by Joint Implementation over the period from 2008 until 2012, is a positive result considering the present situation. Although the agreed cutback falls short of the figures given by climate experts (who demand at least a 20% reduction by the year 2005), the obligation of the USA, the worldwide biggest emitter of greenhouse gases, to achieve a mandatory minimum cutback in emissions of 7% can be considered a big success.

Wenngleich damit die Forderung der Klimaforscher (mindestens 20%-Reduktion bis 2005) nicht erreicht wurde, muss die 7%-Minderungsverpflichtung des weltgroessten Treibhausgasemittenten USA als grosser Erfolg gesehen werden.

    We systematically studied the anomalous Hall effect in a series of polycrystalline Ni films with thickness ranging from 4 to 200 nm. It is found that both the longitudinal and anomalous Hall resistivity increased greatly as film thickness decreased. This enhancement should be related to the surface scattering. In the ultrathin films (46 nm thick), weak localization corrections to anomalous Hall conductivity were studied. The granular model, taking into account the dominated intergranular tunneling, has been employed to explain this phenomenon, which can explain the weak dependence of anomalous Hall resistivity on longitudinal resistivity as well. © 2011 Elsevier Ltd.

    Full Text Available OBJECTIVES: A subset of normotensive Sprague-Dawley rats show lower baroreflex sensitivity; however, no previous study investigated whether there are differences in baroreflex sensitivity within this subset. Our study compared baroreflex sensitivity among conscious rats of this specific subtype. METHODS: Male Wistar Kyoto (WKY rats (16 weeks old were studied. Cannulas were inserted into the abdominal aortic artery through the right femoral artery to measure mean arterial pressure (MAP and heart rate (HR. Baroreflex gain was calculated as the ratio between change in HR and MAP variation (ΔHR/ΔMAP in response to a depressor dose of sodium nitroprusside (SNP, 50 µg/kg, i.v. and a pressor dose of phenylephrine (PE, 8 µg/kg, i.v.. Rats were divided into four groups: 1 low bradycardic baroreflex (LB, baroreflex gain (BG between -1 and -2 bpm/mmHg tested with PE; 2 high bradycardic baroreflex (HB, BG < -2 bpm/mmHg tested with PE; 3 low tachycardic baroreflex (LT, BG between -1 and -2 bpm/mmHg tested with SNP and; 4 high tachycardic baroreflex (HT, BG < -2 bpm/mmHg tested with SNP. Significant differences were considered for p < 0.05. RESULTS: Approximately 37% of the rats showed a reduced bradycardic peak, bradycardic reflex and decreased bradycardic gain of baroreflex while roughly 23% had a decreased basal HR, tachycardic peak, tachycardic reflex and reduced sympathetic baroreflex gain. No significant alterations were noted with regard to basal MAP. CONCLUSION: There is variability regarding baroreflex sensitivity among WKY rats from the same laboratory.

    COGEN Europe believes that the single most important influence on the electricity sector in the future will be the policy response to climate change and that cogeneration offers one of the very best, prospects for cutting emissions in the power sector. In the EU, cogeneration was put at the head of the list of Policies and Measures laid down before Kyoto as the means of achieving its then progressive target of a 15% reduction in emissions by 2010 over 1990. COGEN Europe has estimated that EU-15 as a whole could reach a 30% cogeneration share of total electricity production by 2010. Indeed, three of the 15 countries have already reached 30% (Denmark, The Netherlands and Finland). On a conservative basis this would save 221 Mt of CO 2 /yr by 2010, or 46% of the EU 15% negotiating target agreed in 1997. This also represents 30% of the 'gap' between the achievement of the 15% target and the 8% increase in emissions anticipated for 2010 in the absence of abatement measures. Most, if not all, of these savings would be based on zero or negative cost investments. COGEN Europe supports the trend towards liberalization and the European Commission's efforts to introduce competition into electricity and gas markets for the simple reason that they provide the best means to remove market and monopoly barriers to the development of high efficiency cogeneration. This paper presents a COGEN Europe vision for meeting and overcoming the challenges of global climate change - and some suggestions for governments which can help them achieve that elusive double dividend: environmental improvement and economic competitiveness. Governments should: where possible use the market to achieve your environmental objectives; avoid detailed regulation; avoid subsidizing pollution; set clear and ambitious CO 2 objectives; redouble political pressure to achieve international consensus on internalization of environmental costs

  6. Endogenous induced technical change and the costs of Kyoto

    Many predictions and conclusions in the climate change literature have been made and drawn on the basis of theoretical analyses and quantitative models that are either static or that allow for simple forms of changes in technology, often along exogenously given time paths. It is therefore not clear a priori whether those conclusions and policy recipes still hold in the more realistic case of endogenously evolving technologies. In this paper, a quantitative tool with the features of an endogenous growth model is presented, which also accounts for the possibility that technical change can be induced by environmental policy measures. Both the output production technology and the emission-output ratio depend upon the stock of knowledge, which accumulates through R and D activities. R and D is thus an additional policy variable that comes into play along with pollution abatement and capital investment. Two versions of this climate model are studied, one with endogenous technical change but exogenous environmental technical change (i.e. no induced technical change) and the other with both endogenous and induced technical change. Hence, in both models technical change evolves endogenously as far as the production technology is concerned, but endogenous environmental (or induced) technical change is only accounted for in the second version. Finally, a third version of the model also captures technological spillover effects. As an application, the three versions of the model are simulated allowing for trade of pollution permits as specified in the Kyoto Protocol and assessing the implications in terms of cost efficiency, economic growth and R and D efforts of the three different specifications of technical change

  7. Temperature Gradient in Hall Thrusters

    Plasma potentials and electron temperatures were deduced from emissive and cold floating probe measurements in a 2 kW Hall thruster, operated in the discharge voltage range of 200-400 V. An almost linear dependence of the electron temperature on the plasma potential was observed in the acceleration region of the thruster both inside and outside the thruster. This result calls into question whether secondary electron emission from the ceramic channel walls plays a significant role in electron energy balance. The proportionality factor between the axial electron temperature gradient and the electric field is significantly smaller than might be expected by models employing Ohmic heating of electrons

    This paper examines whether the Kyoto mechanisms have stimulated the diffusion of renewable energy technologies in the BRICS, i.e. Brazil, Russian, India China and South Africa. We examine the patterns of diffusion of renewable energy technologies in the BRICS, the factors associated with their diffusion, and the incentives provided by the Kyoto mechanisms. Preliminary analysis suggests that the Kyoto mechanisms may be supporting the spread of existing technologies, regardless if such technologies are still closely tied to environmental un-sustainability, rather than the development and diffusion of more sustainable variants of renewable energy technologies. This raises questions about the incentives provided by the Kyoto mechanisms for the diffusion of cleaner variants of renewable energy technologies in the absence of indigenous technological efforts and capabilities in sustainable variants, and national policy initiatives to attract and build on Kyoto mechanism projects. We provide an empirical analysis using aggregated national data from the World Development Indicators, the International Energy Agency, the United Nations Framework Convention on Climate Change and secondary sources. - Highlights: ► The Kyoto mechanisms may be supporting the diffusion of existing technologies. ► They may not be supporting the diffusion of sustainable renewable energy technologies. ► In the absence of appropriate capabilities and policies further diffusion is limited.

  10. Nondestructive hall coefficient measurements using ACPD techniques

    Hall coefficient measurements offer great opportunities as well as major challenges for nondestructive materials characterization. The Hall effect is produced by the magnetic Lorentz force acting on moving charge carriers in the presence of an applied magnetic field. The magnetic perturbation gives rise to a Hall current that is normal to the conduction current but does not directly perturb the electric potential distribution. Therefore, Hall coefficient measurements usually exploit the so-called transverse galvanomagnetic potential drop effect that arises when the Hall current is intercepted by the boundaries of the specimen and thereby produce a measurable potential drop. In contrast, no Hall potential is produced in a large plate in the presence of a uniform normal field at quasi-static low frequencies. In other words, conventional Hall coefficient measurements are inherently destructive since they require cutting the material under tests. This study investigated the feasibility of using alternating current potential drop (ACPD) techniques for nondestructive Hall coefficient measurements in plates. Specifically, the directional four-point square-electrode configuration is investigated with superimposed external magnetic field. Two methods are suggested to make Hall coefficient measurements in large plates without destructive machining. At low frequencies, constraining the bias magnetic field can replace constraining the dimensions of the specimen, which is inherently destructive. For example, when a cylindrical permanent magnet is used to provide the bias magnetic field, the peak Hall voltage is produced when the diameter of the magnet is equal to the diagonal of the square ACPD probe. Although this method is less effective than cutting the specimen to a finite size, the loss of sensitivity is less than one order of magnitude even at very low frequencies. In contrast, at sufficiently high inspection frequencies the magnetic field of the Hall current induces a

    New analytical and numerical results of the dynamics of inhomogeneous, reversed field current layers in the Hall limit (i.e., characteristic length scales < or approx. the ion inertial length) are presented. Specifically, the two- and three-dimensional evolution of a current layer that supports a reversed field plasma configuration and has a density gradient along the current direction is studied. The two-dimensional study demonstrates that a density inhomogeneity along the current direction can dramatically redistribute the magnetic field and plasma via magnetic shock-like or rarefaction waves. The relative direction between the density gradient and current flow plays a critical role in the evolution of the current sheet. One important result is that the current sheet can become very thin rapidly when the density gradient is directed opposite to the current. The three-dimensional study uses the same plasma and field configuration as the two-dimensional study but is also initialized with a magnetic field perturbation localized along the current channel upstream of the plasma inhomogeneity. The perturbation induces a magnetic wave structure that propagates in the direction of the electron drift (i.e., opposite to the current). The propagating wave structure is a Hall phenomenon associated with magnetic field curvature. The interaction between the propagating wave structure and the evolving current layer can lead to rapid magnetic field line reconnection. The results are applied to laboratory and space plasma processes

    In Japan eleven research reactors are in operation. After the 19th International Meeting on Reduced Enrichment for Research Reactors and Test Reactors (RERTR) on October 6-10, 1996, Seoul, Korea, the Five Agency Committee on Highly Enriched Uranium, which consists of Science and Technology Agency, the Ministry of Education, Science and Culture, the Ministry of Foreign Affairs, Japan Atomic Energy Research Institute (JAERI) and Kyoto University Research Reactor Institute (KURRI) met on November 7,1996, to discuss the handling of spent fuel from research reactors in Japan. Advantages and disadvantages to return spent fuel to the USA in comparison to Europe were discussed. So far, a number of spent fuel elements in JAERI and KURRI are to be returned to the US. The first shipment to the US is planned for 60 HEU elements from JMTR in 1997. The shipment from KURRI is planned to start in 1999. (author)

    We consider the quantum Hall effect in quantum electrodynamics and find a deviation from the quantum-mechanical prediction for the Hall conductivity due to radiative antiscreening of electric charge in an external magnetic field. A weak dependence of the universal von Klitzing constant on the magnetic field strength, which can possibly be observed in a dedicated experiment, is predicted

    Efficiency of electric motors and generators is reduced by radial magnetic forces created by symmetric fields within device. Forces are sensed and counteracted by Hall devices on excitation or control windings. Hall generators directly measure and provide compensating control of anu asymmetry, eliminating additional measurements needed for calibration feedback control loop.

    The general plan of constructing the TRISTAN e + e - colliding beam experimental halls may be divided into two parts. The first step is to construct two test-experimental halls associated with the 6.5 GeV x 6.5 GeV e + e - accumulator ring, and the second step is to build four experimental halls at the 30 GeV x 30 GeV e + e - TRISTAN main ring. At this workshop, extensive discussions on the detailed design of the four main ring experimental halls have been made. Four experimental areas will be built at the main ring, and two test-experimental halls at the accumulating ring. Among the four areas at the main ring, two will be used for electron-proton possible as well as electron-positron colliding beam experiment. The other two will be used exclusively for e + e - colliding experiments. Only a preliminary design has been made for these four experimental areas. A tentative plan of a larger experimental hall includes a counting and data processing room, a utility room, and a radiation safety control room. Two smaller halls have simpler structure. The figures of the experimental halls are presented. The two test-experimental halls at the accumulator ring will be used to test the detectors for e + e - colliding experiments before the final installation. The utility rooms designed for the halls are used to supply coolant and electric power of superconducting magnets. At the workshop, various ideas concerning the preliminary plan are presented.

    The quantum Hall effect in semiconductor heterostructures is explained by two signs in the angular momentum j=l±s and g=(2j+1)/(2l+1) along with the Landau factor (n+1/2). These modifications in the existing theories explain all of the fractional charges. The helicity which is the sign of the product of the linear momentum with the spin p.s plays an important role for the understanding of the data at high magnetic fields. In particular it is found that particles with positive sign in the spin move in one direction and those with negative sign move in another direction which explains the up and down stream motion of the particles.

    Full Text Available Stuart Hall (3 February 1932 – 10 February 2014 is acknowledged as one of the founding figures of British Cultural Studies. His extensive academic work on topics such as race, ethnicity and identity reflects his own position as a diasporic intellectual. His contribution to the study of popular culture is determined by the importance of his political character in every social act, his non-deterministic view of Marxism, and is especially determined by his insistence on playing an active role beyond academia in order to contribute to the transformation of hegemonic structures. The following biography aims to give a focused view of his personal history and its direct influence on his key theoretical reflections.

  1. The fractional quantum Hall effect

    1988-01-01

    The fractional quantum Hall effect (FQHE), is the manifestation of a new, highly correlated, many-particle ground state that forms in a two-dimensional electron system at low temperatures and in high magnetic fields. It is an example of the new physics that has grown out of the tremendous recent advances in semiconductor material science, which has provided us with high-quality, lower-dimensional carrier systems. The novel electronic state exposes itself in transport experiments through quantization of the Hall resistance to an exact rational fraction of h/e, and concomitantly vanishing longitudinal resistivity. Its relevant energy scale is only a few degrees kelvin. The quantization is a consequence of the spontaneous formation of an energy gap separating the condensed ground state from its rather elusive quasiparticle excitations. The theoretical understanding of the novel quantum liquids which underlie the FQHE has predominantly emerged from an ingenious many-particle wave function strongly supported by numerous few-particle simulations. Theory has now constructed a complex model for ideal two-dimensional electron systems in the presence of high magnetic fields and makes definitive, often fascinating predictions. Experiments have successively uncovered odd-denominator fractional states reaching presently to 7/13. The application of new experimental tools to the FQHE, such as optics, microwaves, and phonon techniques promises the direct observation of such parameters as the gap energy and possibly even some of the more elusive quantities in the future. While theory and experiment in the FQHE appear to be converging, there remains considerable room for challenging surprises. This paper provides a concise overview of the FQHE. It focuses on the experimental aspects and states, but does not expand on the theoretical advances. 70 refs., 11 figs

    The calibration of radiocarbon dates on marine materials involves a global marine calibration with regional corrections. The marine reservoir ages in the Western North Pacific have not been discussed, while it is quite important to determine the timing of palaeo-environmental changes as well as archaeological interpretation around this region. The lack of adequate collection of the pre-bomb shell from western north Pacific was the biggest problem. Recently we had a chance to examine specimens from an old shell collection stored in Kyoto University, including shell specimens from Japan, Korea, Taiwan and the Micronesia of 1920s and 1930s. We explored the possibility for usage of specimen without clear evidence of live collection by measuring 30 apparent radiocarbon ages of pre-bomb mollusk shells from 18 sites in Western North Pacific. The preliminary results showed several discrepancies with previously reported results and with each other. We have to carefully select the shell specimen that has biological signs such as articulating fulcrum. In order to exploit this big resource of pre-bomb shell collection, the new technique to distinguish fossils from live collected samples should be developed by using chemical and physical methods

    Ten years have passed since December 1997, when the United Nations Framework Convention on Climate Change (UNFCCC) was signed in Kyoto. It's been a decade of tough international negotiations, leading to the beginnings of an international CO 2 emissions trading market, whose future past 2012 remains uncertain. The December negotiations in Bali may not have produced a successor to the Kyoto Protocol, but they did get all parties to the Convention to sign an agreement in principle to post- Kyoto negotiations

    The article presents an economic model study of the implications of an climatic agreement. Two main scenarios are presented: 1) The Kyoto protocol is extended to 2020. 2) All counties ratify a climatic agreement. The conclusions are that the Kyoto protocol may have great effects on the oil and gas markets and large economic consequences for Norway. It is therefore mandatory to extensively use the Kyoto mechanisms such as trade with quotas, common implementation and the green development mechanism

    At the end of 2011, almost all European countries were on track towards their Kyoto targets for 2008-2012. The EU-15 also remained on track to achieve its Kyoto target. Italy, however, was not on track. Spain plans to acquire a large quantity of Kyoto units through the KP's flexible mechanisms to achieve its target. With emission caps already set for the economic sectors under the EU Emissions Trading Scheme (EU ETS), emissions reductions during 2012 in the sectors outside the EU ETS together with reductions by carbon sinks will set the frame for how many Kyoto units Member States need to acquire to reach their individual targets. Hence, both the development and delivery of adequate plans to acquire enough Kyoto credits is becoming increasingly important. ETS emissions from 2008 to 2011 were on average 5 % below these caps, which results in an oversupply of allowances. The EU ETS is undergoing important changes in view of the third trading phase from 2013 to 2020. Most EU Member States project that in 2020, their emissions outside the EU ETS will be lower than their national targets set under the Climate and Energy Package. However, further efforts will be necessary to achieve longer term reductions. (Author)

    2011-01-01

    Full Text Available Shinsengumi, a group of young men recruited by the Bakufu to protect Kyoto from radical Imperial House loyalists in the tumultuous Bakumatsu period, is romanticised and idolised in Japan despite its limited place in history. This article attempts to comprehend this phenomenon by locating the closest crystallisation of popularly imagined Shinsengumi in Moeyo ken, a popular historical fiction by Shiba Ryōtarō. Antonio Gramsci explains readers are attracted to popular literature because it reflects their ‘philosophies of the age’, which may be discovered by examining popular heroes with their subsequent replications. This article will identify why Shinsengumi is appealing by comparing Shiba’s hero in Moeyo ken with its twenty-first century reincarnation in Gintama, a popular manga series, and by discerning reader response to Moeyo ken from customer reviews on Amazon.co.jp. It will be demonstrated from these studies that a likely reason for the Japanese public’s romanticisation of Shinsengumi in recent years could be their attraction to autonomous, self-determining heroes who also appreciate the value of community.

    The Quantum Hall Effects offer a rich variety of theoretical and experimental advances. They provide interesting insights on such topics as gauge invariance, strong interactions in Condensed Matter physics, emergence of new paradigms. This paper focuses on some related philosophical questions. Various brands of positivism or agnosticism are confronted with the physics of the Quantum Hall Effects. Hacking's views on Scientific Realism, Chalmers' on Non-Figurative Realism are discussed. It is argued that the difficulties with those versions of realism may be resolved within a dialectical materialist approach. The latter is argued to provide a rational approach to the phenomena, theory and ontology of the Quantum Hall Effects.

    Whenever the Fermi level lies in a gap (or mobility gap) the bulk Hall conductance can be expressed in a topologically invariant form showing the quantization explicitly. The new formulation generalizes the earlier result by TKNN to the situation where many body interaction and substrate disorder are also present. When applying to the fractional quantized Hall effect we draw the conclusion that there must be a symmetry breaking in the many body ground state. The possibility of writing the fractionally quantized Hall conductance as a topological invariant is also carefully discussed. 19 references

    The electrical control of the magnetization switching in ferromagnets is highly desired for future spintronic applications. Here we report on hybrid piezoelectric (PZT)/ferromagnetic (Co2FeAl) devices in which the planar Hall voltage in the ferromagnetic layer is tuned solely by piezo voltages. The change of planar Hall voltage is associated with magnetization switching through 90° in the plane under piezo voltages. Room temperature magnetic NOT and NOR gates are demonstrated based on the piezo voltage controlled Co2FeAl planar Hall effect devices without the external magnetic field. Our demonstration may lead to the realization of both information storage and processing using ferromagnetic materials.

    2008-01-01

    This paper presents an assessment of the impact of the Kyoto Protocol on the Iberian Electricity Market during two periods: the first phase (2005-2007) and the second phase (2008-2012). A market-equilibrium model is used in order to analyze different conditions faced by generation companies. Scenarios involving CO 2 -emission prices, hydro conditions, demand, fuel prices and renewable generation are considered. This valuation will show the significance of CO 2 -emission prices as regards Spanish and Portuguese electricity prices, generation mix, utilities profits and the total CO 2 emissions. Furthermore, the results will illustrate how energy policies implemented by regulators are critical for Spain and Portugal in order to mitigate the negative impact of the Kyoto Protocol. In conclusion, the Iberian electricity system will not be able to reach the Kyoto targets, except in very favorable conditions (CO 2 -emission prices over Euro 15/ton and the implementation of very efficient energy policies)

    International Nuclear Information System (INIS)

    Knoepfel, Ivo

    1999-01-01

    The implementation of the Kyoto Protocol in the context of the Framework Convention on Climate Change will probably lead to economic winners and losers in various sectors of the economy. Especially carbon intensive industries will need to develop hedging strategies to prevent potential negative effects and to optimise market opportunities. Such strategies can be based on technological innovation, market and product diversification, and on financial/legal offsets. The Kyoto Protocol has introduced new market-based instruments, which can, in a near future provide such hedging opportunities. These include joint implementation, the so-called clean development mechanism, and international emissions trading. The financial services and insurance sector are the natural partners of industry in designing tailored hedging strategies. It is recommended that industry, financial services and insurance companies take a more proactive role in further developing the market-based instruments established by the Kyoto Protocol. (Author)

    An integrated approach to climate change and regional air pollution can harvest considerable ancillary benefits in terms of environmental impacts and costs. This is because both problems are caused to a large extent by the same activity (fossil fuel combustion). Substantial ancillary benefits were found for regional air pollution (SO 2 , NO x , VOC and particulate matter) of implementing the Kyoto Protocol (intended to control greenhouse gas emissions) in Europe. For instance, while three different scenarios on Kyoto implementation were found to reduce European CO 2 emissions by 4-7%, they also reduced European emissions of SO 2 by 5-14% compared with a no Kyoto policies case. The magnitude of ancillary benefits depends on how flexible mechanisms and surplus emission allowances are used in meeting the Kyoto targets. The total cost savings for implementing current policies for regional air pollution of the Kyoto Protocol are of an order of 2.5-7 billion Euro. In all cases, this is in the order of half the costs of the climate policy (4-12 billion Euro). Using flexible mechanisms reduces emissions of air pollutants for Europe as a whole even further than domestic implementation (e.g. 10-14% versus 5% for SO 2 emissions), but the reductions are shifted from Western Europe to Central and Eastern Europe and Russia. The use of surplus emission allowances to achieve the Kyoto targets decreases the ancillary benefits, in particular for the latter group of countries (e.g. unprotected area against acidification increases from 1.3 to 1.7 million ha)

The author also proposes a theoretical contribution to the Hall Effect and reports the calculation of conditions to be met to obtain a correct value for the Hall constant. Results are experimentally verified. The method is then applied to the study of a set of powdered pre-graphitic graphites. The author shows that their Hall coefficient confirms the model already proposed by Mrozowski. The study of the Hall Effect of any kind of powders can thus be performed, and the Hall Effect can therefore be a mean to study mineral and organic compounds, and notably powdered biological molecules [fr

    The authors measure the Hall angle, θ H , in YBCO films in the far- and mid-infrared to determine the temperature and frequency dependence of the Hall scattering. Using novel modulation techniques they measure both the Faraday rotation and ellipticity induced by these films in high magnetic fields to deduce the complex conductivity tensor. They observe a strong temperature dependence of the mid-infrared Hall conductivity in sharp contrast to the weak dependence of the longitudinal conductivity. By fitting the frequency dependent normal state Hall angle to a Lorentzian θ H (ω) = ω H /(γ H minus iω) they find the Hall frequency, ω H , is nearly independent of temperature. The Hall scattering rate, γ H , is consistent with γ H ∼ T 2 up to 200 K and is remarkably independent of IR frequency suggesting non-Fermi liquid behavior

  18. Climate change ratification of the Kyoto Protocol : clearing the air on the debate

    The Kyoto Protocol on Climate Change would commit Canada to limit emissions of greenhouse gases to 6 per cent below 1990 levels by 2008-2012. The Canadian Chamber of Commerce has outlined the following 3 key prerequisites that the federal government should and will have in place before any decision on ratification is made: (1) a detailed plan for achieving the Kyoto reductions, (2) a detailed analysis of environmental and economic impacts associated with Kyoto implementation, and (3) consultations with all stakeholder and the Canadian public once the plan has been released. Currently, Canadian businesses are taking voluntary actions to reduce industrial sector emissions through programs such as the Canadian Industry Program for Energy Conservation. Between 1990 and 1999, industrial sector emissions fell by 6 per cent. However, it was emphasized that despite these efforts, the gap between Canada's Kyoto target and its current greenhouse gas emissions continues to grow because of population and economic growth and rising exports. At the current rate of growth, it is estimated that meeting the Kyoto target could cost the economy up to $30 billion in 2010. The paper also discusses the implementation of key flexibility mechanisms such as carbon sinks, Joint Implementation, the Clean Development Mechanism and credits for export of cleaner energy to the United States, a non-Kyoto country. It is argued that ratification of Kyoto could hurt investments and impact jobs in Canada by making Canadian industries uncompetitive relative to their American counterparts. It is emphasized that full participation by the Canadian public is required in adapting to major lifestyle changes to reduce the use of fossil fuels and other sources of greenhouse gases. In conclusion, the Canadian Chamber of Commerce does not believe that the Kyoto Protocol is the most effective and efficient way of moving forward on the climate change issue and recommends that the federal government develop a made

    American president George W. Bush has declared that he will not ask the Senate to ratify the Kyoto Protocol. This commentary explores the potential impact of implementing the Kyoto Protocol without the participation of the United States. Because, in practice, the United States would have taken on a relatively large share of the Protocol's abatement commitments, we conclude that implementing the Protocol without the participation of United States will lead to significantly less reductions in global emissions. The international permit price will be considerably lower if the United States does not participate. (author)

    The quantum magnetotransport properties of a monolayer of molybdenum disulfide are derived using linear response theory. In particular, the effect of topological terms on longitudinal and Hall conductivity is analyzed. The Hall conductivity exhibits fractional steps in the integer quantum Hall regime. Further complete spin and valley polarization of the longitudinal conductivitity is seen in presence of these topological terms. Finally, the Shubnikov-de Hass oscillations are suppressed or enhanced contingent on the sign of these topological terms.

    This book presented the results of a 2 year research project which developed post-2012 climate regime scenarios. The aim of the project was to contribute to decision-making and dialogue between policy-makers and stakeholders. A range of scenarios for a post-2012 framework were developed which illustrated the many possible futures under which the global climate regime may evolve. Scenarios include the strengthening of a binding-cap approach; a bottom-up evolution of emission markets on a global scale; a regime consisting of multiple treaties among like-minded countries and a binding-cap regime with an emphasis on equity. Papers in this book explored key building blocks of a future climate regime, and presented ideas on how to broaden the current cap-and-trade regime. The roles and importance of technology were explored. Lessons from past successes were reviewed with the aim of developing options for their most effective use in the near future. The issue of financial flows to developing countries was addressed, including the issue of mainstreaming assistance for climate-change response. It was suggested that European countries will be key players in initial negotiations in the post-2012 regime, and that the current framework favours Europe while making it difficult for the United States, Japan and Canada to make ambitious commitments. It was concluded that a careful analysis of all the alternative paths available for international climate policies is needed. refs., tabs., figs

    The collective plasmonic modes of a metal comprise a simple pattern of oscillating charge density that yields enhanced light-matter interaction. Here we unveil that beneath this familiar facade plasmons possess a hidden internal structure that fundamentally alters its dynamics. In particular, we find that metals with nonzero Hall conductivity host plasmons with an intricate current density configuration that sharply departs from that of ordinary zero Hall conductivity metals. This nontrivial internal structure dramatically enriches the dynamics of plasmon propagation, enabling plasmon wave packets to acquire geometric phases as they scatter. At boundaries, these phases accumulate allowing plasmon waves that reflect off to experience a nonreciprocal parallel shift. This plasmon Hall shift, tunable by Hall conductivity as well as plasmon wavelength, displaces the incident and reflected plasmon trajectories and can be readily probed by near-field photonics techniques. Anomalous plasmon geometric phases dramatically enrich the nanophotonics toolbox, and yield radical new means for directing plasmonic beams.

    Full Text Available The Hall effect is the generation of a current perpendicular to both the direction of the applied electric as well as magnetic field in a metal or in a semiconductor. It is used to determine the concentration of electrons. The quantum Hall effect with integer quantization was discovered by von Klitzing and fractionally charged states were found by Tsui, Stormer and Gossard. Robert Laughlin explained the quantization of Hall current by using “flux quantization” and introduced incompressibility to obtain the fractional charge. We have developed the theory of the quantum Hall effect by using the theory of angular momentum. Our predicted fractions are in accord with those measured. We emphasize our explanation of the observed phenomena. We use spin to explain the fractional charge and hence we discover spin-charge locking.

    Highlights: • The time-dependent Ginzburg–Landau was used to calculate fluctuation Hall conductivity and Hall angle in type-II superconductor in 2D and 3D. • We obtain analytical expressions for the fluctuation Hall conductivity and the Hall angle summing all Landau levels without need to cutoff higher Landau levels to treat arbitrary magnetic field. • The results were compared to the experimental data on YBCO. - Abstract: The fluctuation Hall conductivity and the Hall angle, describing the Hall effect, are calculated for arbitrary value of the imaginary part of the relaxation time in the frame of the time-dependent Ginzburg–Landau theory in type II-superconductor with thermal noise describing strong thermal fluctuations. The self-consistent Gaussian approximation is used to treat the nonlinear interaction term in dynamics. We obtain analytical expressions for the fluctuation Hall conductivity and the Hall angle summing all Landau levels without need to cutoff higher Landau levels to treat arbitrary magnetic field. The results are compared with experimental data on high-T{sub c} superconductor.

    Plasma perturbations in the acceleration channel of a Hall thruster are found to be unstable in the presence of collisions. Both electrostatic lower-hybrid waves and electromagnetic Alfven waves transverse to the applied electric and magnetic field are found to be unstable due to collisions in the E X B electron flow. These results are obtained assuming a two-fluid hydrodynamic model in slab geometry. The characteristic frequencies of these modes are consistent with experimental observations in Hall current plasma thrusters

    The authors suggest that the origin of the odd-denominator rule observed in the fractional quantized Hall effect (FQHE) may lie in fractional statistics which govern quasiparticles in FQHE. A theorem concerning statistics of clusters of quasiparticles implies that fractional statistics do not allow coexistence of a large number of quasiparticles at fillings with an even denominator. Thus, no Hall plateau can be formed at these fillings, regardless of the presence of an energy gap. 15 references

    The present volume consists of the combined proceedings of two Japan-USA Collaborative Workshops, organized to explore historical developments of particle theory in Japan during the period 1930-1960, i.e., the three decades that include the birth and development of Meson Theory. The first phase of workshops was held during September 1978-July 1979 and the second during July 1984-September 1985. The original versions of these proceedings were published informally; namely, the former was distributed as a series of preprints of the Yukawa Institute (then called RIFP) entitled 'Particle Physics in Japan, 1930-50 Vol. I, II' (RIFP-407 and -408, September 1980); the latter was issued in the form of camera-ready printing from Yukawa Hall Archival Library (YHAL) in May 1988, under the title 'Elementary Particle Theory in Japan, 1935-1960'. Only a small number of copies were printed for both sets of proceedings due to financial limitations of the project. (author)

    This article examines competition in Japan and its link to postwar economic prosperity. While Japan's industrial structure and competition policy seem to indicate that competition in Japan has been less intense, the empirical evidence does not support this conclusion. The sectors in which competition was restricted prove to be those where Japan was not internationally successful. In the internationally successful sectors, internal competition in Japan was invariably fierce. While the level of...

  17. Estimates of the costs of Kyoto: Marrakesh versus the McKibbin-Wilcoxen blueprint

    International Nuclear Information System (INIS)

    McKibbin, Warwick J.; Wilcoxen, Peter J.

    2004-01-01

    In this paper, we update our earlier estimates of the cost of the Kyoto Protocol using the G-Cubed model, taking into account the new sink allowances from recent negotiations as well as allowing for multiple gases and new land clearing estimates. We then compare the protocol to an alternative policy outlined in McKibbin et al. (Brookings Policy Brief, No. 17. June, The Brookings Institution, Washington, 1997; Climate Change Policy After Kyoto: A Blueprint for a Realistic Approach, The Brookings Institution, Washington, 2002a; J. Econom. Perspect. 16(2) (2002b) 107) that does not impose rigid emissions targets. We focus particular attention on the sensitivity of compliance costs under each policy to unexpected changes in future economic conditions. To illustrate the issue, we evaluate the policies under two plausible alternative assumptions about a single aspect of the future world economy: the rate of productivity growth in Russia. We find that moderate growth in Russia would raise the cost of the Kyoto Protocol by as much as 50 percent but would have little effect on the cost of the alternative policy. We conclude that the Kyoto Protocol is inherently unstable because unexpected future events could raise compliance costs substantially and place enormous pressure on governments to abrogate the agreement. The alternative policy would be far more stable because it does not subject future governments to adverse shocks in compliance costs

    The Kyoto Protocol to the United Nations Framework Convention on Climate Change aims to reduce greenhouse gas emissions by urging the international community to take measures preventing 'dangerous man-made interference with the climate system'. Since its publication in 1997, the Kyoto Protocol has triggered heated debates among scientists and politicians. According to a number of critics, the questions as to whether global warming is caused by human intervention, and whether taking appropriate measures could reduce the trend, has not yet been conclusively answered. In a limited number of countries, this situation has led to a delay in the ratification process. Only when these disputes were settled in February 2005 the Kyoto Protocol became legally binding on all the signatories. If predictions are accurate, measures have to be taken to prevent a global catastrophe. This leads to another, much overlooked, but no less important question, namely how mankind can be motivated to accept the burden attached to the measures proposed by the Kyoto Protocol; in other words, how do we find and formulate an ethical basis for measures forcing us to sacrifice some of our wealth and riches, for a cleaner, more sustainable world?

    2008-01-01

    The objective of this paper is to assess the economic impacts of reducing greenhouse gas emissions by decreasing industrial output in Canada to a level that will meet the target set out in the Kyoto Protocol. The study uses an ecological-economic Input-Output model combining economic components valued in monetary terms with ecologic components - GHG emissions - expressed in physical terms. Economic and greenhouse gas emissions data for Canada are computed in the same sectoral disaggregation. Three policy scenarios are considered: the first one uses the direct emission coefficients to allocate the reduction in industrial output, while the other two use the direct plus indirect emission coefficients. In the first two scenarios, the reduction in industrial sector output is allocated uniformly across sectors while it is allocated to the 12 largest emitting industries in the last one. The estimated impacts indicate that the results vary with the different allocation methods. The third policy scenario, allocation to the 12 largest emitting sectors, is the most cost effective of the three as the impacts of the Kyoto Protocol reduces Gross Domestic Product by 3.1% compared to 24% and 8.1% in the first two scenarios. Computed economic costs should be considered as upper-bounds because the model assumes immediate adjustment to the Kyoto Protocol and because flexibility mechanisms are not incorporated. The resulting upper-bound impact of the third scenario may seem to contradict those who claim that the Kyoto Protocol would place an unbearable burden on the Canadian economy. (author)

  7. The Kyoto Protocol Emissions Trading Mechanisms - A Model for financing future nuclear development in Romania

    International Nuclear Information System (INIS)

    Purica, Ionut; John Saroudis

    2001-01-01

    At the beginning of 2001 Romania ratified the Kyoto Protocol (Law 3/2001) thus becoming the first European country to do so. The mechanisms of the Kyoto Protocol are now opening new ways to sponsor the financing of nuclear projects. In May 2001 Societatea Nationala Nuclearoelectrica S.S. (SNN) and Atomic Energy of Canada Limited and ANSALDO of Italy signed a contract to complete the second CANDU unit at Cernavoda thus giving a new momentum to the nuclear program in Romania. The Government of Romania has indicated its desire to proceed with the completion of the other units on the Cernavoda site and is open to explore every potential financing mechanism to make this a reality. Although the Kyoto Protocol was not ratified by those countries that have the greatest need to reduce emissions, a market for emissions trading has developed, Canada being one of the important players in this market. Since the emission reduction per dollar invested in the Romanian nuclear program would bring much more reduction than the marginal reduction per dollar invested in environmental protection programs in Canada, where the saturation effect is already taking place, we consider that the application of the Kyoto Protocol mechanisms represents a realistic source for a sustainable cooperation of the two countries. This trend is in line with the latest activities of the International Atomic Energy Agency (IAEA). This paper analyzes the impact that the use of emissions credits would have on a typical financing scheme for a future CANDU project in Romania given the present situation and also proposes a model for the structure of the emissions trade that would generate a source of funding for the project. The conclusion is that there is real potential in using Kyoto Protocol mechanisms for financing nuclear development with benefits for both Romania and Canada. (authors)

    At the end of 2010, the EU-15 was on track to achieve its Kyoto target but three EU-15 Member States (Austria, Italy and Luxembourg) were not on track to meet their burden-sharing targets. These countries must therefore seriously consider further action to ensure compliance, in particular revising their plans on using flexible mechanisms. Among the EEA member countries outside the EU, Liechtenstein and Switzerland were not on track to achieve their Kyoto target at the end of 2009. All other European countries are on track to meet their targets, either based on domestic emissions only or with the assistance of Kyoto mechanisms. The economic recession had a significant impact on the EU's total greenhouse gas (GHG) emission trends but a more limited effect on progress towards Kyoto targets. This is because emissions in the sectors covered by the EU Emissions Trading Scheme (ETS), which were most affected by the crisis, do not affect Kyoto compliance once ETS caps have been set. With existing national measures, Member States do not project enough emission reductions for the EU to meet its unilateral 20 % reduction commitment in 2020. Additional measures currently planned by Member States will help further reduce emissions but will be insufficient to achieve the important emission cuts needed in the longer term. By 2020 Member States must enhance their efforts to reduce emissions in non-EU ETS sectors, such as the residential, transport or agriculture sectors, where legally binding national targets have been set under the EU's 2009 climate and energy package.

    International workshop on II Polarized Partons at High Q2 region 11 was held at the Yukawa Institute for Theoretical Physics, Kyoto University, Kyoto, Japan on October 13-14, 2000, as a satellite of the international conference ''SPIN 2000'' (Osaka, Japan, October 16-21,2000). This workshop was supported by RIKEN (The Institute of Physical and Chemical Research) and by Yukawa Institute. The scientific program was focused on the upcoming polarized collider RHIC. The workshop was also an annual meeting of RHIC Spin Collaboration (RSC). The number of participants was 55, including 28 foreign visitors and 8 foreign-resident Japanese participants, reflecting the international nature of the RHIC spin program. At the workshop there were 25 oral presentations in four sessions, (1) RHIC Spin Commissioning, (2) Polarized Partons, Present and Future, (3) New Ideas on Polarization Phenomena, (4) Strategy for the Coming Spin Running. In (1) the successful polarized proton commissioning and the readiness of the accelerator for the physics program impressed us. In (2) and (3) active discussions were made on the new structure function to be firstly measured at RHIC, and several new theoretical ideas were presented. In session (4) we have established a plan for the beam time requirement toward the first collision of polarized protons. These proceedings include the transparencies presented at the workshop. The discussion on ''Strategy for the Coming Spin Running'' was summarized by the chairman of the session, S. Vigdor and G. Bunce.

  11. Charge carrier coherence and Hall effect in organic semiconductors

    2016-01-01

    Hall effect measurements are important for elucidating the fundamental charge transport mechanisms and intrinsic mobility in organic semiconductors. However, Hall effect studies frequently reveal an unconventional behavior that cannot be readily explained with the simple band-semiconductor Hall effect model. Here, we develop an analytical model of Hall effect in organic field-effect transistors in a regime of coexisting band and hopping carriers. The model, which is supported by the experiments, is based on a partial Hall voltage compensation effect, occurring because hopping carriers respond to the transverse Hall electric field and drift in the direction opposite to the Lorentz force acting on band carriers. We show that this can lead in particular to an underdeveloped Hall effect observed in organic semiconductors with substantial off-diagonal thermal disorder. Our model captures the main features of Hall effect in a variety of organic semiconductors and provides an analytical description of Hall mobility, carrier density and carrier coherence factor.

    Hall effect measurements are important for elucidating the fundamental charge transport mechanisms and intrinsic mobility in organic semiconductors. However, Hall effect studies frequently reveal an unconventional behavior that cannot be readily explained with the simple band-semiconductor Hall effect model. Here, we develop an analytical model of Hall effect in organic field-effect transistors in a regime of coexisting band and hopping carriers. The model, which is supported by the experiments, is based on a partial Hall voltage compensation effect, occurring because hopping carriers respond to the transverse Hall electric field and drift in the direction opposite to the Lorentz force acting on band carriers. We show that this can lead in particular to an underdeveloped Hall effect observed in organic semiconductors with substantial off-diagonal thermal disorder. Our model captures the main features of Hall effect in a variety of organic semiconductors and provides an analytical description of Hall mobility, carrier density and carrier coherence factor.

    Herbert James Hall, MD (1870-1923), was a pioneer in the systematic and organized study of occupation as therapy for persons with nervous and mental disorders that he called the "work cure." He began his work in 1904 during the early years of the Arts and Crafts Movement in the United States. His primary interest was the disorder neurasthenia, a condition with many symptoms including chronic fatigue, stress, and inability to work or perform everyday tasks. The prevailing treatment of the day was absolute bed rest known as the "rest cure." Hall believed that neurasthenia was not caused by overwork but by faulty living habits that could be corrected through an ordered life schedule and selected occupations. He identified several principles of therapy that are still used today including graded activity and energy conservation. Dr. Adolph Meyer credits Hall for organizing the ideas on the therapeutic use of occupation (Meyer, 1922). Hall also provided the name American Occupational Therapy Association for the professional organization and served as the fourth president. For his many contributions to the profession Hall deserves to be recognized as a major contributor to the development and organization of occupational therapy.

    The new angular position sensor consists of a combination of a permanent magnet attached to a shaft and of a two-axis magnetic sensor. The permanent magnet produces a magnetic field parallel with the magnetic sensor plane. As the shaft rotates, the magnetic field also rotates. The magnetic sensor is an integrated combination of a CMOS Hall integrated circuit and a thin ferromagnetic disk. The CMOS part of the system contains two or more conventional Hall devices positioned under the periphery of the disk. The ferromagnetic disk converts locally a magnetic field parallel with the chip surface into a field perpendicular to the chip surface. Therefore, a conventional Hall element can detect an external magnetic field parallel with the chip surface. As the direction of the external magnetic field rotates in the chip plane, the output voltage of the Hall element varies as the cosine of the rotation angle. By placing the Hall elements at the appropriate places under the disk periphery, we may obtain the cosine signals shifted by 90 , 120 , or by any other angle. (orig.)

    The quantum Hall effect and associated quantum transport phenomena in low-dimensional systems have been the focus of much attention for more than a decade. Recent theoretical development of interesting quasiparticles - 'composite fermions' - has led to significant advances in understanding and predicting the behaviour of two-dimensional electron systems under high transverse magnetic fields. Composite fermions may be viewed as fermions carrying attached (fictitious) magnetic flux. Here we review models of the integer and fractional quantum Hall effects, including the development of a unified picture of the integer and fractional effects based upon composite fermions. The composite fermion picture predicts remarkable new physics: the formation of a Fermi surface at high magnetic fields, and anomalous ballistic transport, thermopower, and surface acoustic wave behaviour. The specific theoretical predictions of the model, as well as the body of experimental evidence for these phenomena are reviewed. We also review recent edge-state models for magnetotransport in low-dimensional devices based on the composite fermion picture. These models explain the fractional quantum Hall effect and transport phenomena in nanoscale devices in a unified framework that also includes edge state models of the integer quantum Hall effect. The features of the composite fermion edge-state model are compared and contrasted with those of other recent edge-state models of the fractional quantum Hall effect. (author)

    In the rooms with dominant sensible heat load, volume airflow depends on many factors incl. pre-established temperature difference between exhaust and supply airflow. As the temperature difference is getting higher, airflow volume drops down, consequently, the cost of AHU is reduced. In high industrial halls with air exhaust grids located under the ceiling additional temperature gradient above working zone should be taken into consideration. In this regard, experimental research of the vertical air temperature gradient in high industrial halls were carried out for the case of mixing ventilation system The paper presents the results of air temperature distribution measurements in high technological hall (mechanically ventilated) under significant sensible heat load conditions. The supply airflow was delivered to the hall with the help of the swirl diffusers while exhaust grids were located under the hall ceiling. Basing on the air temperature distribution measurements performed on the seven pre-established levels, air temperature gradient in the area between 2.0 and 7.0 m above the floor was calculated and analysed.

    The Fradkin's formulation of statistical field theory is applied to the Coulomb interacting electron gas in a magnetic field. The electrons are confined to a plane in normal 3D-space and also interact with the physical 3D-electromagnetic field. The magnetic translation group (MTG) Ward identities are derived. Using them it is shown that the exact electron propagator is diagonalized in the basis of the wave functions of the free electron in a magnetic field whenever the MTG is unbroken. The general tensor structure of the polarization operator is obtained and used to show that the Chern-Simons action always describes the Hall effect properties of the system. A general proof of the Streda formula for the Hall conductivity is presented. It follows that the coefficient of the Chern-Simons terms in the long-wavelength approximation is exactly given by this relation. Such a formula, expressing the Hall conductivity as a simple derivative, in combination with diagonal form of the full propagator allows to obtain a simple expressions for the filling factor and the Hall conductivity. Indeed, these results, after assuming that the chemical potential lies in a gap of the density of states, lead to the conclusion that the Hall conductivity is given without corrections by σ xy = νe 2 /h where ν is the filling factor. In addition it follows that the filling factor is independent of the magnetic field if the chemical potential remains in the gap. (author). 21 ref, 1 fig

  18. Extrinsic spin Hall effect in graphene

    Science.gov (United States)

    Rappoport, Tatiana

    The intrinsic spin-orbit coupling in graphene is extremely weak, making it a promising spin conductor for spintronic devices. In addition, many applications also require the generation of spin currents in graphene. Theoretical predictions and recent experimental results suggest one can engineer the spin Hall effect in graphene by greatly enhancing the spin-orbit coupling in the vicinity of an impurity. The extrinsic spin Hall effect then results from the spin-dependent skew scattering of electrons by impurities in the presence of spin-orbit interaction. This effect can be used to efficiently convert charge currents into spin-polarized currents. I will discuss recent experimental results on spin Hall effect in graphene decorated with adatoms and metallic cluster and show that a large spin Hall effect can appear due to skew scattering. While this spin-orbit coupling is small if compared with what it is found in metals, the effect is strongly enhanced in the presence of resonant scattering, giving rise to robust spin Hall angles. I will present our single impurity scattering calculations done with exact partial-wave expansions and complement the analysis with numerical results from a novel real-space implementation of the Kubo formalism for tight-binding Hamiltonians.

    Ten years have passed since December 1997, when the United Nations Framework Convention on Climate Change (UNFCCC) was signed in Kyoto. It's been a decade of tough international negotiations, leading to the beginnings of an international CO{sub 2} emissions trading market, whose future past 2012 remains uncertain. The December negotiations in Bali may not have produced a successor to the Kyoto Protocol, but they did get all parties to the Convention to sign an agreement in principle to post- Kyoto negotiations.

    The localization problem of electronic states in a two-dimensional quantum spin Hall system (that is, a symplectic ensemble with topological term) is studied by the transfer matrix method. The phase diagram in the plane of energy and disorder strength is exposed, and demonstrates "levitation" and "pair annihilation" of the domains of extended states analogous to that of the integer quantum Hall system. The critical exponent nu for the divergence of the localization length is estimated as nu congruent with 1.6, which is distinct from both exponents pertaining to the conventional symplectic and the unitary quantum Hall systems. Our analysis strongly suggests a different universality class related to the topology of the pertinent system.

  2. Hall probe magnetometer for SSC magnet cables

    The authors of this paper constructed a Hall probe magnetometer to measure the magnetization hysteresis loops of Superconducting Super Collider magnet cables. The instrument uses two Hall-effect field sensors to measure the applied field H and the magnetic induction B. Magnetization M is calculated from the difference of the two quantities. The Hall probes are centered coaxially in the bore of a superconducting solenoid with the B probe against the sample's broad surface. An alternative probe arrangement, in which M is measured directly, aligns the sample probe parallel to the field. The authors measured M as a function of H and field cycle rate both with and without a dc transport current. Flux creep as a function of current was measured from the dependence of ac loss on the cycling rate and from the decay of magnetization with time. Transport currents up to 20% of the critical current have minimal effect on magnetization and flux creep

    We present a microscopic theory of the extrinsic spin Hall effect based on the diagrammatic perturbation theory. Side-jump (SJ) and skew-scattering (SS) contributions are explicitly taken into account to calculate the spin Hall conductivity, and we show their effects scale as σxy^SJ/σxy^SS ˜(/τ)/ɛF, where τ being the transport relaxation time. Motivated by recent experimental work we apply our theory to n-doped and p-doped 3D and 2D GaAs structures, obtaining analytical formulas for the SJ and SS contributions. Moreover, the ratio of the spin Hall conductivity to longitudinal conductivity is found as σs/σc˜10-3-10-4, in reasonable agreement with the recent experimental results of Kato et al. [Science 306, 1910 (2004)] in n-doped 3D GaAs system.

    The Superconducting Super Collider which is being designed and built in Waxahachie, Texas consists Of series of proton accelerators, culminating in a 20 Te proton on proton collider. The collider will be in a tunnel which will be 87 km in circumference and. on average about 30 meters underground. The present design calls for two large interaction halls on the east side of the ring. The shielding for these halls is being designed for an interaction rate of 10 9 Hz or 10 16 interactions per year, based on 10 7 seconds per operational year. SSC guidelines require that the shielding be designed to meet the criterion of 1mSv per year for open areas off site 2mSv per year for open areas on site, and 2mSv per year for controlled areas. Only radiation workers will be routinely allowed to work in controlled areas. It should be pointed that there is a potential for an accidental full beam loss in either of the experimental halls, and this event would consist of the loss of the full circulating beam up to 4 x 10 14 protons. With the present design. the calculated dose equivalent for this event is about 10% of the annual dose equivalent for the normal p-p interactions, so that die accident condition does not control the shielding. If, for instance, local shielding within the experimental hall is introduced into the calculations, this could change. The shielding requirements presented here are controlled by the normal p-p interactions. Three important questions were addressed in the present calculations. They are (1) the thickness of the roof over the experimental halls, (2) the configuration of the shafts and adits which give access to the halls, and (3) the problem of ground water and air activation

    Low temperature scanning Hall probe microscopy is a sensitive means of imaging magnetic structures with high spatial resolution and magnetic flux sensitivity approaching that of a Superconducting Quantum Interference Device. We have developed a scanning Hall probe microscope with novel features, including highly reliable coarse positioning, in situ optimization of sensor-sample alignment and capacitive transducers for linear, long range positioning measurement. This has been motivated by the need to reposition accurately above fabricated nanostructures such as small superconducting rings. Details of the design and performance will be presented as well as recent progress towards time-resolved measurements with sub nanosecond resolution.

    The cylindrical thruster differs significantly in its underlying physical mechanisms from the conventional annular Hall thruster. It features high ionization efficiency, quiet operation, ion acceleration in a large volume-to-surface ratio channel, and performance comparable with the state-of-the-art conventional Hall thrusters. Very significant plume narrowing, accompanied by the increase of the energetic ion fraction and improvement of ion focusing, led to 50-60% increase of the thruster anode efficiency. These improvements were achieved by overrunning the discharge current in the magnetized thruster plasma

Tinkham, Nature (London) 442, 176 (2006)], the authors present a quantitative microscopic theory to investigate the inverse spin-Hall effect with spin injection into aluminum considering both intrinsic and extrinsic spin-orbit couplings using the orthogonalized-plane-wave method. Their theoretical results are in good agreement with the experimental data. It is also clear that the magnitude of the anomalous Hall resistivity is mainly due to contributions from extrinsic skew scattering.

An order parameter is introduced and a gap in the single particle spectrum is found. The critical temperature, critical filling number and critical behaviour are determined as well as the Ginzburg-Landau equation coefficients. A first principle calculation of the Hall current is given. 3, 5, 7 electron tunneling and Josephson interference effects are predicted. (author)

    Observations of microtremors were carried out to estimate the S-wave velocity structure by using arrays of seismographs around the Kyoto Research Park. The observation points were so arranged that equilateral triangle arrays may be formed with maximum radii at 0.2 km, 0.4 km and 0.8 km respectively with the premises of the Kyoto Research Park as the center. The seismographs have used seven vertical movement components (PELS), and were adjusted to a period of eight seconds. In addition, high-cut filters of 4 Hz were used because the observation areas are located in urban areas with heavy traffic. The analysis has used the spatial self-correlation method as a means to estimate phase velocity of surface waves contained in microtremors. As a result, phase velocity estimation has become possible for frequencies from about 0.4 Hz to 2 Hz, whereas the S-wave velocity structure was estimated to a depth of down to about 900 m by using as reference the result of the reflection method exploration having been carried out in the present areas. In addition, it was suggested that microtremors with frequencies higher than 1 Hz are in unsteady state in terms of time or space. 4 refs., 7 figs., 1 tab.

    The kyoto university reactor physics experiments on the university critical assembly is used to benchmark validate the NCNSRC calculations methodology. This methodology has two lines, diffusion and Monte Carlo. The diffusion line includes the codes WIMSD4 for cell calculations and the two dimensional diffusion code DIXY2 for core calculations. The transport line uses the MULTIKENO-Code vax Version. Analysis is performed for the criticality, and the temperature coefficients of reactivity (TCR) for the light water moderated and reflected cores, of the different cores utilized in the experiments. The results of both Eigen value and TCR approximately reproduced the experimental and theoretical Kyoto results. However, some conclusions are drawn about the adequacy of the standard wimsd4 library. This paper is an extension of the NCNSRC efforts to assess and validate computer tools and methods for both Et-R R-1 and Et-MMpr-2 research reactors. 7 figs., 1 tab

    The climatic behavior of the planet and its consequences has favored debates about the models of development of the countries responsible for the accelerated deterioration of the atmosphere and of the natural phenomena by these recurrent days. Nevertheless, countries as United States, after signing commitments as the Convention on Climatic Change, refuse to acquire the obligations of the Kyoto Protocol, from fear of undergoing deterioration in their economies. In this setting, where the nation responsible for the emission of approximately 36% of the turned out effect greenhouse gases result of the human action in the planet does not commit itself to adopt restrictive policies to make its models of production but friendly with the nature although these measures begin to be imposed to other nations as determining factors in the international commercial negotiations, seems to be that the adoption of the Kyoto Protocol for developing countries as Colombia is not absolutely beneficial

    2003-01-01

    This study introduces a transparent, operational model of estimating soil respiration (SR) to meet the requirements of the Kyoto Protocol of the United Nation Framework Convention on Climate Change within a framework of full carbon accounting (Nilsson et al.; 2000). By applying this model, we are able to define SR for the Kyoto 1990 baseline year for Russia (3200 Tg C), and establish soil emission thresholds for any spatial units, e.g. vegetation zones and land-use patterns. This model is built upon a fundamental biogeochemical cycle and provides a scientific basis for carbon management. SR comprised about 74% of the photosynthetically assimilated carbon in 1990, with the remainder accounted for in several areas. The carbon flux balance is, therefore, found to be closed for Russia. Our findings suggest that incomplete accounting is the reason for missing carbon globally

    In the last two decades increasing attention has been paid to the relationship between environmental degradation and economic development. According to the Environmental Kuznets Curve (EKC) hypothesis this relationship may be described by an inverted-U curve. However, recent evidence rejects the EKC hypothesis for GHG emissions in a broad sense. In this paper we aim to investigate whether the EKC behavior for CO2 emissions could be proved on the behalf of institutional regulations. We analyze the driving factors of CO2 for developed and developing countries to test the theory of the EKC in the context of environmental regulations using a static and dynamic panel data model. We consider the Kyoto Protocol and the Clean Development Mechanism (CDM). The results from this study indicate that the Kyoto obligations have a reducing effect on CO2 emissions in developed and developing countries. (orig.)

Rather than being the economic disaster as characterized by the provincial government and the oil industry, the implementation costs of the Kyoto Protocol are likely to be much more incremental than Alberta's apocalyptic scenario suggests. With respect to cost, the author bolsters his case by citing the experience of British Petroleum Limited which has already reduced GHG emissions to 10 per cent below 1990 levels at 'no economic cost'. He argues that the 'made-in-Canada' environmental policy suggested by Alberta is no more likely to succeed than did the 'made-in-Canada' oil price policy in 1980. He makes a strong argument for the Kyoto Protocol as an opportunity to create federal-provincial strategies for all of Canada, and makes a strong case for institutional changes that would respect the legitimacy of federal and provincial interests in environmental policy issues. Given genuine effective leadership in Ottawa and in the provincial capitals, such changes could be an important step in the direction of increased reliance on one another as we try to secure a better future for all Canadians, and at the same time doing our bit in ensuring the survival of the planet.

    2000-01-01

    At the 43rd regular session of the IAEA General Conference, Member States requested the IAEA to help countries in assessing nuclear power's role in light of global environmental challenges and energy needs. Such assistance should include support for implementing national case studies, and facilitating access to relevant information about nuclear power's role in achieving sustainable development in developing countries and in mitigating GHG emissions. The dissemination of information on CDM is of particular importance to developing countries, so as to enable Member States interested in the mechanism to take an active and informed role in the debate regarding the Kyoto Protocol and eligible CDM technologies. Therefore, the Secretariat organized a series of information seminars, workshops and training courses for Member States on the Kyoto Protocol, the Clean Development Mechanism, Joint Implementation and Emissions Trading with particular emphasis on the potential role of nuclear power for GHG mitigation. On request, the Secretariat also provided training and assistance to several Member States in the preparation of national case studies that explore the potential role of nuclear power as a CDM technology. These case studies will be presented by the respective national study teams during this side event at the 44th IAEA General Conference. Within the general criteria included in the Kyoto Protocol, the decision on which technologies are eligible for GHG mitigation under the flexibility mechanisms is a sovereign decision of each country

    The long-term increase in Earth's temperature is known as the global warming or the greenhouse effect. Taking into account the fact that the ice age only involved a global temperature variation of around 4 C, it is clear climate change is arguably one of the greatest environmental threats the world is facing today. The impacts of disruptive change leading to catastrophic events such as storms, droughts, sea level rise and floods are already being felt across the world. In this context, the signing of the Kyoto Protocol in 1997 has been argued to be a historic step in reversing the inexorable increase in the emission of the greenhouse gases. The primary achievement of the Protocol has been so-called commitment of countries referred in the Annex I of the Protocol to reduce their emission of GHGs some 5% below their country specific 1990 level. On February 5, 2009, Turkish Parliament ratified an agreement to sign the Kyoto Protocol after intense pressure from both the European Union and international environmental organizations; however, so far it has not taken any step to bring about real reductions in emissions. In short, Turkey simply signed but ignored the Protocol. Present paper investigates Turkish position vis-a-vis Kyoto Protocol and critically questions Turkish policies in that area. (author)

  7. Is the Kyoto Protocol an adequate environmental agreement to resolve the climate change problem?

    The lack of understanding on how to handle the issue of global warming, which is embodied by the Kyoto Protocol, among the various nations of the world reached a point where environmental policy-makers saw a number of possible scenarios to global warming before the last meeting on Climate Change in July 2001 in Bonn: Amendments to the Kyoto Protocol, by changing the current targets and timetable into a long-term view of the global warming issue. The U.S. does not agree with the Kyoto Protocol Therefore, it will not do anything about it in terms of its ratification. A middle ground between the two previous options. The idea is the creation of a new mechanism where nations meet in international environmental for a voluntarily exchange of views with no legal commitments. In order to move forward, we should stop thinking of the global warming issue only in a cost-benefit analysis and instead take more into account public health and safety requirements. Since the U.S. and EU representatives may well find themselves deadlocked again when they meet at the end of October 2001 in Morocco for the next climate change convention, the author would like to make some recommendations at the end of this article.

    The Kyoto Protocol obliges the Republic of Croatia to reduce greenhouse gas emissions by 5 percent till the year 2010, taking a base year from the period between 1985 and 1990. Thermal power plants of Hrvatska Elektroprivreda (HEP) represent significant source of the most important greenhouse gas - CO 2 - and consequently HEP is expected to make a significant contribution to the national activities aiming to meet the Kyoto Protocol requirements. This issue is of particular importance, as Croatia has not submitted its base year to the Conference of the Parties in form of The National Communication on Climate Change, which is one of the requirements of UN Climate Change Convention and the Kyoto Protocol. Related to this, it is interesting to include emissions from the thermal power plants located in Bosnia and Herzegovina and Serbia (650 MWe) that had supplied electricity to the Croatian power supply system in the base year period and on which HEP claims legal ownership. This article presents HEP greenhouse gas emissions from the period of 1985 to 1990, as well as its contribution in total greenhouse gas emissions of Croatia. Furthermore, future HEP greenhouse gas emissions, according to its business development scenario till the year 2010, will be estimated. (author)

    This article describes the most important provisions of World Trade Organization (WTO) agreements that should be considered in designing laws and regulations under likely post-Kyoto climate change mitigation regimes. The Kyoto Protocol and the expected post-Kyoto international climate agreement depend on national measures to implement market-based mitigation measures. This market strategy promotes international exchanges of goods, investments, and services such as cross-border trading of credits for emissions reductions and transnational financing for projects that avoid emissions through the Clean Development Mechanism. Moreover, the United States and other countries, concerned over "leakage" of greenhouse gas (GHG) emissions through relocation of industry to other countries coupled with political worry over manufacturing competitiveness, have proposed national climate legislation containing border adjustments on imported goods or implicit subsidies for national producers, raising additional WTO considerations. The article assesses the likely effectiveness of such trade-related measures in achieving climate change mitigation goals and the potential trade policy infringements and trade distortions that they might bring about. Alternative strategies for achieving GHG mitigation goals in closer conformity with WTO law and policy will be suggested.

    Because of its profound economic implications, the Kyoto Protocol merits careful study and active, continued participation on the part of the Colombian private sector. The article presents a brief summary of the main elements of the Protocol and its implications for Colombian business. For the business sector in Colombia, Joint implementation has been a key theme in motivating interest and participation on the issue of climate change. Now, after Kyoto, a new instrument has been created, the Clean Development Mechanism, which may permit international investment in forestry and energy projects that reduce greenhouse gas GHG- emissions. The Kyoto Protocol reduces the risk that Colombia need to assume new emissions reductions commitments, and in this new phase it is logical to focus on the opportunities created by the Protocol and the Framework Convention, especially the Clean Development Mechanism. Colombian business leaders should continue to participate actively in the international negotiations that will establish the rules of the game and in the development of private projects in industry, energy and forestry that capture

    The Kyoto Protocol attempts through political negotiations to guide participating industrialized countries' greenhouse gas (GHG) emissions from a positive growing trend, to reach a peak point (or turning point), and then be reduced to a negative growth. That means the relationship between decreasing GHG emissions and economic growth may be described by an inverted-U curve (or called a bell-shaped curve), which is consistent with the concept of the Environmental Kuznets Curve (EKC) hypothesis. This research observed that the economic development and GHG emissions in Economies in Transition (EITs) exhibit a hockey-stick curve trend (or called quasi-L-shape curve), that also generates a lot of 'hot air' which is significant to the implementation of the Kyoto Protocol. In addition, through the analysis of single-country time series data and GDP data, this research demonstrated that statistical data for most of the Annex II countries do not possess evidence that supports the EKC hypothesis for GHG emissions. The results from this study also indicated that the 38 industrialized countries are unable to meet their targets under the Kyoto Protocol within the specified time period, which are probably caused by the econometric method's inability to predict accurately the extents and development of innovative technologies and Clean Development Mechanism (CDM) projects. If the international community truly wants to reduce the GHG emissions, the effectiveness of the existing international framework for emissions reduction needs to be reconsidered seriously, and the global cooperation mechanism also needs to be greatly enhanced

  13. A Small Modular Laboratory Hall Effect Thruster

    Lee, Ty Davis

    Electric propulsion technologies promise to revolutionize access to space, opening the door for mission concepts unfeasible by traditional propulsion methods alone. The Hall effect thruster is a relatively high thrust, moderate specific impulse electric propulsion device that belongs to the class of electrostatic thrusters. Hall effect thrusters benefit from an extensive flight history, and offer significant performance and cost advantages when compared to other forms of electric propulsion. Ongoing research on these devices includes the investigation of mechanisms that tend to decrease overall thruster efficiency, as well as the development of new techniques to extend operational lifetimes. This thesis is primarily concerned with the design and construction of a Small Modular Laboratory Hall Effect Thruster (SMLHET), and its operation on argon propellant gas. Particular attention was addressed at low-cost, modular design principles, that would facilitate simple replacement and modification of key thruster parts such as the magnetic circuit and discharge channel. This capability is intended to facilitate future studies of device physics such as anomalous electron transport and magnetic shielding of the channel walls, that have an impact on thruster performance and life. Preliminary results demonstrate SMLHET running on argon in a manner characteristic of Hall effect thrusters, additionally a power balance method was utilized to estimate thruster performance. It is expected that future thruster studies utilizing heavier though more expensive gases like xenon or krypton, will observe increased efficiency and stability.

    2011-01-01

    We study the spin-orbital interaction and the spin Hall effect of an electron moving on a noncommutative space under the influence of a vector potential A(vector sign). On a noncommutative space, we find that the commutator between the vector potential A(vector sign) and the electric potential V 1 (r(vector sign)) of the lattice induces a new term, which can be treated as an effective electric field, and the spin Hall conductivity obtains some correction. On a noncommutative space, the spin current and spin Hall conductivity have distinct values in different directions, and depend explicitly on the noncommutative parameter. Once this spin Hall conductivity in different directions can be measured experimentally with a high level of accuracy, the data can then be used to impose bounds on the value of the space noncommutativity parameter. We have also defined a new parameter, σ=ρθ (ρ is the electron concentration, θ is the noncommutativity parameter), which can be measured experimentally. Our approach is based on the Foldy-Wouthuysen transformation, which gives a general Hamiltonian of a nonrelativistic electron moving on a noncommutative space.

    Electronic states with non-trivial topology host a number of novel phenomena with potential for revolutionizing information technology. The quantum anomalous Hall effect provides spin-polarized dissipation-free transport of electrons, while the quantum spin Hall effect in combination with superconductivity has been proposed as the basis for realizing decoherence-free quantum computing. We introduce a new strategy for realizing these effects, namely by hole and electron doping kagome lattice Mott insulators through, for instance, chemical substitution. As an example, we apply this new approach to the natural mineral herbertsmithite. We prove the feasibility of the proposed modifications by performing ab-initio density functional theory calculations and demonstrate the occurrence of the predicted effects using realistic models. Our results herald a new family of quantum anomalous Hall and quantum spin Hall insulators at affordable energy/temperature scales based on kagome lattices of transition metal ions.

    Beginnings of the study of Western sciences, "Rangaku," in Kyoto and Osaka in the late 18th century are reviewed. Profiles and achievements of several active learners are briefly described; they include Koishi Genzui (Osaka-Kyoto), Tsuji Ranshitsu (Kyoto), Kimura Kenkadō (Osaka), and Hashimoto Sōkichi (Osaka). Genzui, after having successfully made good relations with Sugita Genpaku and Ohtsuki Gentaku, leading masters of the Edo school, played a role of an advocator for promoting "Rangaku" in Osaka and Kyoto. As a result, Kenkadō attained the publication of his book "Ikkaku Sankō," a monograph of the Western crude drug unicorn, with the help of Gentaku, who had translated a Dutch reference into Japanese for him. Ranshitsu and Sōkichi were taught the Dutch language by Gentaku; Sōkichi is known as the founder of "Rangaku" in Osaka.

    The triple calamity of 11 March 2011 has dealt a serious blow domestically to the credibility of the Japanese nuclear industry, putting the country's energy policy in flux.The severe impact on the country's infrastructure, the unwieldiness of its bureaucracy and the chaotic political situation preclude Japan's energy policy from explicitly re-orientating itself before the middle of 2012, but political consensus seems to be emerging that the country's mid-term pledge on emission reductions will need to be curtailed.The bill on renewable energy passed under Prime Minister Kan marked a step in the right direction, but was shallow and politically opportunistic. Its future impact on policy is uncertain.With other policy instruments on climate proposed by the Democratic Party of Japan toothless or abandoned, Tokyo's ability to engage in significant mitigation activities domestically is in question.Opposition to a second commitment period to the Kyoto Protocol remains firm; Japan will continue to pursue bilateral mechanisms outside the UNFCCC framework.Given its frail domestic policy and a stated readiness to act internationally outside multilateral frameworks, Japan's promise to carry out significant mitigation activities even in the absence of a clear and comprehensive post-2012 legal instrument should be viewed with a critical eye.(Author)

    2016-07-28

    Quite recently, the magnon Hall effect of spin excitations has been observed experimentally on the kagome and pyrochlore lattices. The thermal Hall conductivity κ{sup xy} changes sign as a function of magnetic field or temperature on the kagome lattice, and κ{sup xy} changes sign upon reversing the sign of the magnetic field on the pyrochlore lattice. Motivated by these recent exciting experimental observations, we theoretically propose a simple realization of the magnon Hall effect in a two-band model on the honeycomb lattice. The magnon Hall effect of spin excitations arises in the usual way via the breaking of inversion symmetry of the lattice, however, by a next-nearest-neighbour Dzyaloshinsky-Moriya interaction. We find that κ{sup xy} has a fixed sign for all parameter regimes considered. These results are in contrast to the Lieb, kagome, and pyrochlore lattices. We further show that the low-temperature dependence on the magnon Hall conductivity follows a T{sup 2} law, as opposed to the kagome and pyrochlore lattices. These results suggest an experimental procedure to measure thermal Hall conductivity within a class of 2D honeycomb quantum magnets and ultracold atoms trapped in a honeycomb optical lattice.

  13. Diagnostics Systems for Permanent Hall Thrusters Development

    Ferreira, Jose Leonardo; Soares Ferreira, Ivan; Santos, Jean; Miranda, Rodrigo; Possa, M. Gabriela

    This work describes the development of Permanent Magnet Hall Effect Plasma Thruster (PHALL) and its diagnostic systems at The Plasma Physics Laboratory of University of Brasilia. The project consists on the construction and characterization of plasma propulsion engines based on the Hall Effect. Electric thrusters have been employed in over 220 successful space missions. Two types stand out: the Hall-Effect Thruster (HET) and the Gridded Ion Engine (GIE). The first, which we deal with in this project, has the advantage of greater simplicity of operation, a smaller weight for the propulsion subsystem and a longer shelf life. It can operate in two configurations: magnetic layer and anode layer, the difference between the two lying in the positioning of the anode inside the plasma channel. A Hall-Effect Thruster-HET is a type of plasma thruster in which the propellant gas is ionized and accelerated by a magneto hydrodynamic effect combined with electrostatic ion acceleration. So the essential operating principle of the HET is that it uses a J x B force and an electrostatic potential to accelerate ions up to high speeds. In a HET, the attractive negative charge is provided by electrons at the open end of the Thruster instead of a grid, as in the case of the electrostatic ion thrusters. A strong radial magnetic field is used to hold the electrons in place, with the combination of the magnetic field and the electrostatic potential force generating a fast circulating electron current, the Hall current, around the axis of the Thruster, mainly composed by drifting electrons in an ion plasma background. Only a slow axial drift towards the anode occurs. The main attractive features of the Hall-Effect Thruster are its simple design and operating principles. Most of the Hall-Effect Thrusters use electromagnet coils to produce the main magnetic field responsible for plasma generation and acceleration. In this paper we present a different new concept, a Permanent Magnet Hall

    We theoretically investigate the quantum Hall effect in a graphene superlattice (GS) system, in which the two valleys of graphene are coupled together. In the presence of a perpendicular magnetic field, an ordinary quantum Hall effect is found with the sequence σxy=ν e^2/h(ν=0,+/-1,+/-2,\\cdots) . At the zeroth Hall platform, a valley-chiral Hall state stemming from the single K or K' valley is found and it is localized only on one sample boundary contributing to the longitudinal conductance but not to the Hall conductivity. Our findings may shed light on the graphene-based valleytronics applications.

  16. Japan and atomic co-operation

    International Nuclear Information System (INIS)

    1965-01-01

    Japan, which is host country for the Ninth Regular Session of the Agency General Conference, has an important programme of nuclear power development to meet future needs. In addition, Japan is active in other applications of atomic energy and is building up a domestic nuclear engineering industry. Japan has profited by the Agency as a channel of international cooperation, and was a party to the first bilateral agreement in which the responsibility for administering safeguards against the diversion of materials to military purposes, was transferred to the Agency. Japan has also lent support to Agency programmes by gifts, training courses, research, and the loan of experts. In 1961, the Japan Atomic Energy Commission (AEC) formulated the 'Long-Range Programme for Development and Utilization of Atomic Energy', on the basis of the economic prospects of nuclear power generation, and the conditions necessary to meet the ever-increasing domestic energy demands. According to this programme, in the light of power reactor development trends overseas, it is expected that nuclear power costs will compete with those of oil burning stations by 1970. On this basis, total nuclear power generating capacity of 1000 MW(e) will be attained by 1970, and 7000 - 9 500M(e) by 1980. As a prelude to the above programme the Japan Atomic Power Company (JAPCO) began construction in 1959 of a graphite-moderated gas-cooled nuclear power station (Improved Calder Hall type) of 165 MW(e) gross capacity. This is now progressing smoothly, and reached criticality in May 1965; it is expected to supply commercial power by the end of this year. The second nuclear power station will be built by the same company on the coast of the Japan Sea, with a light water-moderated reactor of 250 - 300 MW(e) capacity.

    We have considered a simple, square, two-dimensional (2D) PC built of a magneto-optic matrix with square holes. It is shown that using such a magnetophotonic crystal it is possible to deflect a light beam at very large angles by applying a nonzero external magnetic field. The effect is called the giant photonic Hall effect (GPHE) or the magnetic superprism effect. The GPHE is based on magneto-optical properties, as is the photonic Hall effect [B. A. van Tiggelen and G. L. J. A. Rikken, in, edited by V. M. Shalaev (Springer-Verlag, Berlin, 2002), p. 275]; however GPHE is not caused by asymmetrical light scattering but rather by the influence of an external magnetic field on the photonic band structure.

    Defect detection of wire rope for an elevator was investigated through the measurement of magnetic flux leakage. The types of defect usually found in wire rope categorized such as inner and outer wire breakage and wear. The specimens that has artificial defects were magnetized via permanent magnet, and measurement of magnetic flux leakage on the defects was performed with Hall sensor. In wire broken model, a defect smaller than 0.4 mm and 1 mm in depth on outer and inner wire rope, respectively, could be detected well. In wear model, smaller defect could not be detected clearly, however, appearance of changing of total magnetic flux during magnetic pole of the sensor passing through a defect 0.2 mm in depth at 4 mm or above width could make possible to detect it. From the results, the measurement via Hall sensor might be useful tool for defect detection of wire rope.

  20. Infinite symmetry in the quantum Hall effect

    Lütken C.A.

    2014-04-01

    Full Text Available The new states of matter and concomitant quantum critical phenomena revealed by the quantum Hall effect appear to be accompanied by an emergent modular symmetry. The extreme rigidity of this infinite symmetry makes it easy to falsify, but two decades of experiments have failed to do so, and the location of quantum critical points predicted by the symmetry is in increasingly accurate agreement with scaling experiments. The symmetry severely constrains the structure of the effective quantum field theory that encodes the low energy limit of quantum electrodynamics of 1010 charges in two dirty dimensions. If this is a non-linear σ-model the target space is a torus, rather than the more familiar sphere. One of the simplest toroidal models gives a critical (correlation length exponent that agrees with the value obtained from numerical simulations of the quantum Hall effect.

    Full Text Available Stuart Hall sought to internationalise theoretical debates and to create Cultural Studies as interdisciplinary. We chart his theoretical journey through a detailed examination of a series of lectures delivered in 1983 and now published for the first time. In these lectures, he discusses theorists such as E.P. Thompson, Raymond Williams, Louis Althusser, Levi Strauss and Antonio Gramsci, and explores the relationship between ideas and social structure, the specificities of class and race, and the legacies of slavery. We note his turn towards metaphors of divergence and dispersal and highlight how autobiographical and deeply personal Hall is in these lectures, especially in his ego histoire moment of traumatic memory recovery.

  2. Hall magnetohydrodynamics: Conservation laws and Lyapunov stability

    1987-01-01

    Hall electric fields produce circulating mass flow in confined ideal-fluid plasmas. The conservation laws, Hamiltonian structure, equilibrium state relations, and Lyapunov stability conditions are presented here for ideal Hall magnetohydrodynamics (HMHD) in two and three dimensions. The approach here is to use the remarkable array of nonlinear conservation laws for HMHD that follow from its Hamiltonian structure in order to construct explicit Lyapunov functionals for the HMHD equilibrium states. In this way, the Lyapunov stability analysis provides classes of HMHD equilibria that are stable and whose linearized initial-value problems are well posed (in the sense of possessing continuous dependence on initial conditions). Several examples are discussed in both two and three dimensions

    Kostadinov, I.Z.

    1985-08-01

    A theory of the Fractional Quantum Hall Effect is constructed based on magnetic flux fractionization, which lead to instability of the system against selfcompression. A theorem is proved stating that arbitrary potentials fail to lift a specific degeneracy of the Landau level. For the case of 1/3 fractional filling a model 3-particles interaction is constructed breaking the symmetry. The rigid 3-particles wave function plays the role of order parameter. In a BCS type of theory the gap in the single particles spectrum is produced by the 3-particles interaction. The mean field critical behaviour and critical parameters are determined as well as the Ginsburg-Landau equation coefficients. The Hall conductivity is calculated from the first principles and its temperature dependence is found. The simultaneous tunnelling of 3,5,7 etc. electrons and quantum interference effects are predicted. (author)

    2009-01-01

    The degeneracy of energy levels in a quantum dot of Hall fluid, leading to conductance peaks, can be readily derived from the partition functions of conformal field theory. Their complete expressions can be found for Hall states with both Abelian and non-Abelian statistics, upon adapting known results for the annulus geometry. We analyze the Abelian states with hierarchical filling fractions, ν = m/(mp ± 1), and find a non-trivial pattern of conductance peaks. In particular, each one of them occurs with a characteristic multiplicity, which is due to the extended symmetry of the m-folded edge. Experimental tests of the multiplicity can shed more light on the dynamics of this composite edge. (fast track communication)

  14. Generic superweak chaos induced by Hall effect

    Ben-Harush, Moti; Dana, Itzhack

    2016-05-01

    We introduce and study the "kicked Hall system" (KHS), i.e., charged particles periodically kicked in the presence of uniform magnetic (B ) and electric (E ) fields that are perpendicular to each other and to the kicking direction. We show that for resonant values of B and E and in the weak-chaos regime of sufficiently small nonintegrability parameter κ (the kicking strength), there exists a generic family of periodic kicking potentials for which the Hall effect from B and E significantly suppresses the weak chaos, replacing it by "superweak" chaos (SWC). This means that the system behaves as if the kicking strength were κ2 rather than κ . For E =0 , SWC is known to be a classical fingerprint of quantum antiresonance, but it occurs under much less generic conditions, in particular only for very special kicking potentials. Manifestations of SWC are a decrease in the instability of periodic orbits and a narrowing of the chaotic layers, relative to the ordinary weak-chaos case. Also, for global SWC, taking place on an infinite "stochastic web" in phase space, the chaotic diffusion on the web is much slower than the weak-chaos one. Thus, the Hall effect can be relatively stabilizing for small κ . In some special cases, the effect is shown to cause ballistic motion for almost all parameter values. The generic global SWC on stochastic webs in the KHS appears to be the two-dimensional closest analog to the Arnol'd web in higher dimensional systems.

    As was reported in our previous work, accurate, nondisturbing near-anode measurements of the plasma density, electron temperature, and plasma potential performed with biased and emissive probes allowed the first experimental identification of both electron-repelling (negative anode fall) and electron-attracting (positive anode fall) anode sheaths in Hall thrusters. An interesting new phenomenon revealed by the probe measurements is that the anode fall changes from positive to negative upon removal of the dielectric coating, which appears on the anode surface during the course of Hall thruster operation. As reported in the present work, energy dispersion spectroscopy analysis of the chemical composition of the anode dielectric coating indicates that the coating layer consists essentially of an oxide of the anode material (stainless steel). However, it is still unclear how oxygen gets into the thruster channel. Most importantly, possible mechanisms of anode fall formation in a Hall thruster with a clean and a coated anodes are analyzed in this work; practical implication of understanding the general structure of the electron-attracting anode sheath in the case of a coated anode is also discussed

    A Bose–Einstein condensation is formed by composite bosons in the quantum Hall state. A composite boson carries the fundamental charge (−e). We investigate Josephson tunneling of such charges in the bilayer quantum Hall system at the total filling ν=1. We show the existence of the critical current for the tunneling current to be coherent and dissipationless. Our results explain recent experiments due to [L. Tiemann, Y. Yoon, W. Dietsche, K. von Klitzing, W. Wegscheider, Phys. Rev. B 80 (2009) 165120] and due to [Y. Yoon, L. Tiemann, S. Schmult, W. Dietsche, K. von Klitzing, Phys. Rev. Lett. 104 (2010) 116802]. We predict also how the critical current changes as the sample is tilted in the magnetic field. -- Highlights: ► Composite bosons undergo Bose–Einstein condensation to form the bilayer quantum Hall state. ► A composite boson is a single electron bound to a flux quantum and carries one unit charge. ► Quantum coherence develops due to the condensation. ► Quantum coherence drives the supercurrent in each layer and the tunneling current. ► There exists the critical input current so that the tunneling current is coherent and dissipationless.

    Pallister Hall syndrome is autosomal dominant disorder usually diagnosed in infants and children. Current diagnostic criteria include presence of hypothalamic hamartoma, post axial polydactyly and positive family history, but the disease has variable manifestations. Herein we report Pallister Hall syndrome diagnosed in a family where both patients were adults. A 59 year old man developed seizures 4 years prior to our evaluation of him, at which time imaging showed a hypothalamic hamartoma. The seizures were controlled medically. He did well until he had visual changes after a traumatic head injury. Repeat MRI showed slight expansion of the mass with formal visual field testing demonstrating bitemporal hemianopsia. There was no evidence of pituitary dysfunction except for large urine volume. He underwent surgery to debulk the hamartoma and the visual field defects improved. There was no hypopituitarism post-operatively, and the polydyspia resolved. His 29 year old daughter also had seizures and hypothalamic hamartoma. Both patients had had polydactyly with prior surgical correction in childhood. The daughter underwent genetic testing, which revealed a previously undescribed heterozygous single base pair deletion in exon 13 of the GLI3 gene causing a frameshift mutation. Further investigation into family history revealed multiple members in previous generations with polydactyly and/or seizures. Pallister-Hall syndrome is caused by an inherited autosomal dominant or de novo mutation in GLI3 gene. This rare syndrome has not had prevalence defined, however. Generally, diagnoses are made in the pediatric population. Our report adds to the few cases detected in adulthood.

  18. An assessment of the economic and environmental implications for Canada of the Kyoto Protocol

    2000-11-01

    The National Climate Change Process was launched in April 1998 to examine the feasibility and implications of Canada's commitment to the Kyoto Protocol. The Analysis Modelling Group (AMG) was designated to assess the economic and environmental consequences for Canada in achieving the target. This report summarizes the analytical approach, the assumptions, the results and the main findings of the AMG's efforts to analyse the macro-/micro-economic, social, health and environmental implications of the Kyoto Protocol. The role of the AMG was to provide policymakers with guidance on some issues such as the economic implications of different broad policy approaches, the potential costs of greater access to the Kyoto flexibility mechanisms, the sectoral and regional distributions of emissions reductions, and the degree to which Canada's competitive position could be affected by the achievement of the Protocol. The relative importance of greenhouse gas reduction was also discussed along with a review of actions that offer significant potential for emissions reductions. The AMG examined five policy packages or Paths which are differentiated by different degrees of reliance on specific measures and tradable permit systems and by the imposition of sectoral versus national targets. It was concluded that at the national level, attainment of the target results in sustained, long-term negative economic impacts. In the long run, the reduction in gross domestic product (GDP) relative to the business-as-usual case, ranges from 0 to 3 per cent depending on the path-scenario combination. It was emphasized that it is important to provide perspective on these estimates. 37 refs., 64 figs

    The paper gives reasons for low energy efficiency typical of the Serbian economy, which is based on outdated and dirty technologies. The comparison of selected economic indicators and indicators of energy efficiency in both Serbia and the European Union points out the benefits of the Kyoto Protocol implementation due to the growth of competitiveness in the global market. Serbia has no obligation to reduce GHG emissions, the authors point to the proposals whose implementation along with the mechanisms of the Protocol can enable Serbia the access to markets that trade GHG emissions and the access to dedicated funds, self-financing or attracting foreign investments to raise energy efficiency, which will be accompanied by adequate economic benefits. A similar principle can be applied in all countries that are not obliged to reduce GHG emissions. The application of different mechanisms aiming to increase energy efficiency in Serbia, could contribute to the increase of GDP annual growth rate from 5% to 7%, which cannot be achieved by any other economic instrument. Energy efficiency, which is actually a question of competitiveness of each economy, can finance itself through the mechanisms of the Kyoto Protocol by selling excess emissions resulting from improved energy efficiency. - Research highlights: → Serbia is a country with the outdated technology and low energy efficiency values. → Sustainable economic and energetic growth can be stirred by inserting Kyoto Protocol. → By investing in modern technology Serbia could lessen emission into the atmosphere. → Cut of emission in the atmosphere could help reaching certain carbon credit values. → By selling the carbon credit Serbia could do economic growth of 5-7% on a year level.

    The Kyoto Protocol attempts through political negotiations to guide participating industrialized countries' greenhouse gas (GHG) emissions from a positive growing trend, to reach a peak point (or turning point), and then be reduced to a negative growth. That means the relationship between decreasing GHG emissions and economic growth may be described by an inverted-U curve (or called a bell-shaped curve), which is consistent with the concept of the Environmental Kuznets Curve (EKC) hypothesis. This research observed that the economic development and GHG emissions in Economies in Transition (EITs) exhibit a hockey-stick curve trend (or called quasi-L-shape curve), that also generates a lot of 'hot air' which is significant to the implementation of the Kyoto Protocol. In addition, through the analysis of single-country time series data and GDP data, this research demonstrated that statistical data for most of the Annex II countries do not possess evidence that supports the EKC hypothesis for GHG emissions. The results from this study also indicated that the 38 industrialized countries are unable to meet their targets under the Kyoto Protocol within the specified time period, which are probably caused by the econometric method's inability to predict accurately the extents and development of innovative technologies and Clean Development Mechanism (CDM) projects. If the international community truly wants to reduce the GHG emissions, the effectiveness of the existing international framework for emissions reduction needs to be reconsidered seriously, and the global cooperation mechanism also needs to be greatly enhanced.

    The achievements of the Kyoto Protocol were highlighted. These achievements include recognition of the need for Annex 1 countries (developed countries) to define concrete emissions reduction targets to be accomplished by 2012; recognition of specific needs of developing countries; need for measures to anticipate, prevent or minimize the causes of climate change; recognition of the need that climate change policies and measures be cost effective; taking into account that economic development is essential for adopting measures to address climate change; recognition of the principle that corporations should promote a supportive and open international economic system leading to sustainable growth; and recognition that measures taken to combat climate change should not lead to unjustifiable discrimination in international trade. If the targets set at Kyoto are achieved, there will be an effective reduction in greenhouse gases of 5.2 per cent in relation to 1990 levels. The meeting in Buenos Aires should focus on strengthening the guidelines for actions agreed upon in Kyoto. Other major issues on the Buenos Aires Conference of Parties (COP 4) agenda should be to discuss ways and means to helping developing countries to deal with climate change issues within their own territories, agreement about definitive status of the Global Environmental Fund, arriving at a more precise definition of the Clean Development Mechanism, and first and foremost the development of credible national systems (i.e. Annex 1 countries) for the estimation of anthropogenic emission sources and removal by sinks of all greenhouse gases not controlled by the Montreal Protocol on the Ozone Layer, and shaping an adequate non-compliance system

  6. To implicate the private sector in funding: The Kyoto mechanisms and SUMO policies

    Internationally set objectives in the fight against climate change cannot be reached without funding from the private sector. Public money, a scarce resource, must be used as best possible, in particular when it has a leverage effect on private funding. In this respect, feedback from the Kyoto Protocol's clean development mechanism is of interest. On the eve of the 2015 Paris Climate Conference, we must ramp up the mobilization of private resources. Smart unconventional monetary (SUMO) policies could help us toward this goal. Several countries have adopted such policies to cope with macro-economic circumstances or systemic risks. Is the destabilization of the climate not a risk of this sort?

    The reduced enrichment programs for the JRR-2, JRR-3, JRR-4 and JMTR of Japan Atomic Energy Research Institute (JAERI), and the KUR of Kyoto University Research Reactor Institute (KURRI) have been partially completed and are mostly still in progress under the Joint Study Programs with Argonne National Laboratory (ANL). The JMTR and JRR-2 have been already converted to use MEU aluminide fuels in 1986 and 1987, respectively. The operation of the upgraded JRR-3(JRR-3M) has started in March 1990 with the LEU aluminide fuels. Since May 1992, the two elements have been inserted in the KUR. The safety review application for the full core conversion to use LEU silicide in the JMTR was approved in February 1992 and the conversion has been done in January 1994. The Japanese Government approved a cancellation of the KUHFR Project in February 1991, and in April 1994 the U.S. Government gave an approval to utilize HEU in the KUR instead of the KUHFR. Therefore, the KUR will be operated with HEU fuel until 2001. Since March 1994, Kyoto University is continuing negotiation with UKAEA Dounreay on spent fuel reprocessing and blending down of recovered uranium, in addition to that with USDOE.

    Full Text Available We surveyed the attitudes of Japanese medical doctors toward complementary and alternative medicine (CAM in 1999. It is supposed that the situation concerning CAM has been changing recently. The aim of the present study is to survey the attitude of doctors toward CAM again, and to examine changes in attitude over the last 6 years. The attitudes of medical doctors belonging to the Kyoto Medical Association toward CAM were surveyed by a structured, self-administered questionnaire in 1999 and 2005. The results showed that the doctors familiar with the term “CAM”, practicing CAM therapies, and attending meetings or training courses related with CAM, increased significantly from 1999 to 2005. The doctors who possessed knowledge of CAM also increased significantly from 1999 to 2005. Almost all doctors believed in the effectiveness of Kampo (Japanese traditional herbal medicine and acupuncture. The number of doctors who believed in the effectiveness of aromatherapy and ayurveda increased significantly in 2005, compared with 1999. In the near future, 58% of doctors desired to practice CAM therapies. In conclusion, the numbers of doctors who practice CAM therapies, possess CAM knowledge and desire to practice such therapies have increased over the last 6 years in Japan.

    We aimed to investigate whether frequencies of protein-rich food intake were associated with frailty among older Japanese adults. A cross-sectional study was conducted in 2011 among 3843 men and 4331 women in a population-based cohort of Kameoka city, Kyoto Prefecture, Japan. Frailty was assessed by the weighted score based on the 25-item Kihon-Checklist. The frequency of protein-rich food intake was examined as "seafood", "meat", "dairy products", "eggs", and "soy products". The outcome of frailty was analyzed with a multiple logistic regression model using the frequency of protein-rich food intake. When compared to the first quartile, it was observed that there was a significant association between the lower adjusted prevalence ratio (PR) for frailty and the frequency of seafood intake in the fourth quartile among men (PR 0.64, 95% confidence interval (CI), 0.42, 0.99) and from the second quartile to the third quartile among women (PR 0.61, 95% CI, 0.43, 0.85; PR 0.64, 95% CI, 0.46, 0.91). The frequency of dairy products intake in the third quartile among women was significantly associated with a lower PR for frailty ( p -value = 0.013). Our findings suggest that the consumption of seafood and dairy products may help older adults in maintaining their independence.

    Full Text Available Efforts are underway in Japan to promote “Smartway” next-generation roadways, which provide a variety of services through the use of advanced ITS technologies. In recent years, the National Institute for Land and Infrastructure Management (NILIM, part of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT, has conducted public–private joint research on next-generation road services using ITS technologies. Field operational tests (FOTs of services including forward obstacle information provision and merging assistance using 5.8 GHz dedicated short range communication (DSRC were conducted on the Tokyo Metropolitan Expressway through FY2007. In FY2008–2009, FOTs were conducted in three major metropolitan areas—Tokyo, Nagoya, and Keihanshin (Kyoto, Osaka, and Kobe—to promote future deployment nationwide. These included tests of information provision services to alert drivers to forward obstacles hidden beyond the crest of an incline and prevent excessive speed on sharp curves. This paper presents an overview of these FOTs conducted by NILIM in recent years and their results.

    Full Text Available El comportamiento climático del planeta y sus consecuencias han propiciado debates sobre los modelos de desarrollo de los países responsables del deterioro acelerado del ambiente y de los fenómenos naturales por estos días recurrentes. Sin embargo, países como Estados Unidos, luego de firmar compromisos como la Convención sobre Cambio Climático, rehúsan adquirir las obligaciones del Protocolo de Kyoto, por temor a sufrir deterioro en sus economías. En este escenario, donde la nación responsable de la emisión de aproximadamente 36% de los gases efecto invernadero resultado de la acción humana en el planeta no se compromete a adoptar políticas restrictivas tendientes a hacer sus modelos de producción más amigables con la naturaleza a pesar de que dichas medidas empiezan a ser impuestas a otras naciones como condicionantes en las negociaciones comerciales internacionales, parece ser que la adopción del Protocolo de Kyoto para países en desarrollo como Colombia no es del todo benéfica.

  15. Emission trading and Kyoto's protocol: discussions concerning rules and international coordination

    2000-01-01

    The Kyoto Protocol of the Climate Convention introduced the possibility to trade greenhouse gas emission reductions among industrialized countries, as a means to reduce the total cost of achieving the agreed emission goals. The rules for this international co-ordination regime are still debated, even if its principle is generally agreed. This article, written before the negotiation in the Hague, summarizes how the notion of emission trading made its way in the Framework Convention on Climate Change. The authors show what economic gains could realistically be expected from emission trading, based on macro-economic modelling results and a simulation of trading in the conditions of the Kyoto Protocol. They stress the critical contribution that emission trading could make, provided that the Protocol's environmental basis is not undermined. In the end, the negotiation collapsed over this issue. Beyond this near-term obstacle, the international emission trading system represents a significant progress towards an efficient resolution of man-made global climate change. (author)

    Objective The Kyoto gastritis classification categorizes the endoscopic characteristics of Helicobacter pylori (H. pylori) infection-associated gastritis and identifies patterns associated with a high risk of gastric cancer. We investigated its efficacy, comparing scores in patients with H. pylori-associated gastritis and with gastric cancer. Methods A total of 1,200 patients with H. pylori-positive gastritis alone (n=932), early-stage H. pylori-positive gastric cancer (n=189), and successfully treated H. pylori-negative cancer (n=79) were endoscopically graded according to the Kyoto gastritis classification for atrophy, intestinal metaplasia, fold hypertrophy, nodularity, and diffuse redness. Results The prevalence of O-II/O-III-type atrophy according to the Kimura-Takemoto classification in early-stage H. pylori-positive gastric cancer and successfully treated H. pylori-negative cancer groups was 45.1%, which was significantly higher than in subjects with gastritis alone (12.7%, pgastritis scores of atrophy and intestinal metaplasia in the H. pylori-positive cancer group were significantly higher than in subjects with gastritis alone (all pgastritis classification may thus be useful for detecting these patients.

    The KART (Kumatori Accelerator-driven Reactor Test facility) project started in Research Reactor Institute, Kyoto University in fiscal year 2002 with the grant by the Japanese Ministry of Education, Culture, Sports, Science and Technology. The purpose of this research project is to demonstrate the basis feasibility of accelerator driven system (ADS), studying the effect of incident neutron energy on the effective multiplication factor in a subcritical nuclear fuel system. For this purpose, a variable-energy FFAG (Fixed Field Alternating Gradient) accelerator complex is being constructed to be coupled with the Kyoto University Critical Assembly (KUCA). The FFAG proton accelerator complex consists of ion-beta, booster and main rings. This system aims to attain 1 μA proton beam with energy range from 20 to 150 MeV with a repetition rate of 120 Hz. The first beam from the FFAG complex is expected to be available by the end of FY 2005, and the experiment on ADS with KUCA and the FFAG complex (FFAG-KUCA experiment) will start in FY 2006. Before the FFAG-KUCA experiment starts, preliminary experiments with 14 MeV neutrons are currently being performed using a Cockcroft-Walton type accelerator coupled with the KUCA. Experimental data are analyzed using continuous energy Monte-Carlo codes MVP, MCNP and MNCP-X. (author)

    The US decision not to ratify the Kyoto Protocol and the recent outcomes of the Bonn and Marrakech Conferences of the Parties have important implications for both the effectiveness and the efficiency of future climate policies. Among these implications, those related with technical change and with the functioning of the international market for carbon emissions are particularly relevant, because these variables have the largest impact on the overall abatement cost to be borne by Annex B countries in the short and in the long run. This paper analyses the consequences of the US decision to withdraw from the Kyoto/Bonn Protocol both on technological innovation and on the price of emission permits (and, as a consequence, on abatement costs). A first goal is to assess the impact of the US defection on the price of permits and compliance costs when technological innovation and diffusion is taken into account (the model embodies international technological spillovers). A second goal is to understand for what reasons in the presence of endogenous and induced technical change the reduction of the price of permits is lower than in most empirical analyses recently circulated. A third goal is to assess the role of Russia in climate negotiations, its increased bargaining power and its eventual incentives to follow the US defections

    One of the most serious and current environmental global problems is the Climate Change generated by the increasing of Green House gas (GHG) level. Romania has signed the United Nation Framework Convention on Climate Change and is the first country listed in Convention Annex I which ratified Kyoto Protocol. Romania committed itself to lower the level of GHG emissions with 8% as compared with the GHG emissions level in 1989, what is similar to the commitment of EU countries. In order to satisfy the requirements of accession to the European Union, Romania has also developed several national strategies to promote sustainable development. Hidroelectrica's Environmental Policy includes international partnership to finance the hydropower projects under Kyoto Protocol of United Nation Framework Convention on Climate Change. Hidroelectrica has submitted Joint Implementation projects to the PCF program of World Bank and ERUPT programs of Dutch Government. The paper reflects Hidroelectrica's experience in that field: the actions necessary to initiate and promote such projects, the steps recommended in developing their implementation, difficulties and barriers, results obtained, learned lessons.

    The liberalization of the Greek electric market (Law 2773/99, updated with Laws 3175/2003 and 3426/2005 for incorporating Directive 2003/54 into the Greek legislation) is in its final structural transformation, which includes the fact that from 1.7.2007 each customer can select its electricity provider. This new status together with the procedure towards the formation of a post-Kyoto plan, raise the need of examining different energy saving strategies in the consumption side for evaluating their economic and environmental consequences. Such strategies may be useful for the decision makers or the electricity retail companies. This paper examines the influence of several post-Kyoto electricity consumption strategies in the Greek interconnected electric system for the period 2005-2025. The aim of the paper is to be used as a decision makers' tool for investigating the potential of electricity consumption policies. The results show that policies related either to seasonal peak demand control, or targeting at the total electric consumption lead to significant gains and emission reduction. Moreover the influence of factors, such as the weather conditions, the discount rate of the energy investments, the fuel prices evolution and the consumers' behavior linkage with oil prices are examined

    This article evaluates the environmental effectiveness and economic implications of the Kyoto Protocol (KP) after the Bonn agreement and the Marrakesh Accords. We will break it down into several components that correspond with major steps in the international process: pre-COP 6 version of the KP, with unrestricted international emissions trading but without sinks; withdrawal of the USA; and decisions on sinks in Bonn and Marrakesh. The Marrakesh Accords bring Annex-I emissions in 2010 without the USA at 0.5% under base-year levels; this corresponds to nearly 2% above the 1990-levels. The US withdrawal has by far the greatest impact in reducing the environmental effectiveness of the KP, whereas the impact of the decision on sinks is comparatively small. The US withdrawal also substantially reduces the permit demand and permit prices will drop dramatically. Hot air becomes increasingly dominant and may threaten the viability of the Kyoto Mechanisms (KM), especially in lower baseline (business-as-usual (BaU)) scenarios. Therefore, banking of hot air is of absolute importance to improve the environmental effectiveness of the protocol at moderately higher costs, while enhancing the development of a viable emission trading market. A strategy of curtailing and banking permit supply is also in the interest of the dominant seller, Russia

    Full Text Available According to the Kyoto Protocol, Slovenia is required to reduce GHG emissions to an average of 8% below base year 1986 emissions in the period 2008-2012. Slovenia established different measures for reducing GHG emissions long before its ratification. It was first transition country who implemented CO2 tax in the 1997. Several changes in CO2 tax have not brought the desired results. CO2 emissions have actually increased. At the beginning of 2005, Slovenia joined other EU member states by implementing the emissions trading instrument, defined by new EU Directive. At the same time, Slovenia has adopted a new CO2 tax system, which is compatible with the new circumstances. The main purpose of this paper is to present the characteristics of Slovenian approach to national allocation plan for emissions trading and analyze the problems of the CO2 tax in Slovenia. Paper also describes the compliance cost of achieving the Kyoto target and expected movements on the Slovenian allowances market.

    In Slovenia the actual fast growth of greenhouse emissions will require substantial efforts to fulfil the target set in Kyoto. The end-use emissions in the in the industrial sectors represented one third of the total CO 2 emissions in the country in 1996. The cost-effective potential in the sector for CO 2 emission reduction is significant. In the paper, the most important ongoing energy efficiency activities in the industrial sector are presented: information and awareness building, energy advising to larger industrial consumers, energy audition programme, demonstration programme of energy efficiency technologies, financial incentives for energy efficiency investment and the energy efficiency investment fund. A CO 2 tax has been in force since 1997. The results of an evaluation of energy efficiency strategies in industry in the frame of the project 'Integrated resource planning for the energy efficiency in Slovenia' are discussed from the viewpoint of greenhouse gases reduction targets set by Slovenia, and a brief information on the ongoing and expected post Kyoto activities and studies is given. The most important points of the future GHG reduction strategy related to industrial sector in Slovenia will be focused on intensified energy efficiency programme, increased combined heat and power production (CHP), and the effects of incentives through the CO 2 tax.

    In 1879, while a graduate student under Henry Rowland at the Physics Department of The Johns Hopkins University, Edwin Herbert Hall discovered what is now universally known as the Hall effect. A symposium was held at The Johns Hopkins University on November 13, 1979 to commemorate the lOOth anniversary of the discovery. Over 170 participants attended the symposium which included eleven in­ vited lectures and three speeches during the luncheon. During the past one hundred years, we have witnessed ever ex­ panding activities in the field of the Hall effect. The Hall effect is now an indispensable tool in the studies of many branches of condensed matter physics, especially in metals, semiconductors, and magnetic solids. Various components (over 200 million!) that utilize the Hall effect have been successfully incorporated into such devices as keyboards, automobile ignitions, gaussmeters, and satellites. This volume attempts to capture the important aspects of the Hall effect and its applications. It includes t...

    We designed a 200 W Hall thruster based on the technology of pushing down a magnetic field with two permanent magnetic rings. Boron nitride (BN) is an important insulating wall material for Hall thrusters. The discharge characteristics of the designed Hall thruster were studied by replacing BN with titanium (Ti). Experimental results show that the designed Hall thruster can discharge stably for a long time under a Ti channel. Experiments were performed to determine whether the channel and cathode are electrically connected. When the channel wall and cathode are insulated, the divergence angle of the plume increases, but the performance of the Hall thruster is improved in terms of thrust, specific impulse, anode efficiency, and thrust-to-power ratio. Ti exhibits a powerful antisputtering capability, a low emanation rate of gas, and a large structural strength, making it a potential candidate wall material in the design of low-power Hall thrusters.

    The reduced enrichment programs for the JRR-3M, JRR-4 and JMTR of Japan Atomic Energy Research Institute (JAERI) have been completed. The KUR of Kyoto University Research Reactor Institute (KURRI) has been partially completed and is still in progress under the Joint Study Program with Argonne National Laboratory (ANL). The JRR-3M commenced using LEU silicide fuel elements instead of LEU aluminide fuel elements in September, 1999. The Japanese Government approved a cancellation of the KUHFR Project in February 1991, and April 1994 the U.S. Government gave an approval to utilize HEU fuel in the KUR instead of the KUHFR. Therefore, the KUR will be operated with HEU fuel until March 2004, then the full core conversion with LEU silicide will be done. The first shipment of spent fuels since 1974 was done in August, 1999. (author)

    This article presents a brief historical record concerning the Brazilian institutional arrangement given to the Kyoto Protocol and, based on the Brazilian emissions profile, discusses general perspectives to the use of the CDM, mainly in projects involving co-generation in the agricultural sector. It is observed high uncertainty about the liquidity and development of the carbon credit market, above all, with reference to the definition of the second period of the Kyoto Protocol commitments. Even so, with the consolidation of the institutional environment, the carbon credit market must become favorable to the projects of co-generation in agricultural sector, especially in countries as Brazil.

    This document provides data and operations needed to evaluate the impacts of the nuclear phaseout on the respect of the Kyoto protocol. The data are based on the belgium electricity production. The author concludes that the nuclear power plants shutdown will lead to a non respect of the kyoto protocol in unacceptable limits. To respect the protocol, he presents two possibilities: the today nuclear park and the use of 1600 wind turbines of 2 MW, or the improvement of the energy efficiency of the thermal power plants.

    This paper reports results of gravity survey and seismic survey using the shallow bed reflection method to identify distribution of the Hanaore fault in the Kyoto urban area. In the gravity survey, level differential structure caused by the fault was identified as an abrupt change in Bouger anomalous values. The continuity therefrom made the estimation possible on existence and positions of such faults as the Hanaore fault belonging to the Hanaore fault system, the Shishigaya fault, the Kaguraoka fault, and the Okazaki fault. The estimation as a result of the gravity survey include the following findings: the Hanaore fault runs from south of the Yoshidayama in the south-north direction; the distribution of the Okazaki fault has a level differential structure falling on the east side; the structure shows low Bouger anomaly distribution; and this area forms a rift valley belt. In the seismic survey using the shallow bed reflection method, no distinct reflection plane considered as the basement was verified because of influence from urban area noise. However, it was possible to estimate such an underground structure as a monoclinal fold from shapes of the reflection plane and the distribution depths. 7 refs., 5 figs.

    Canada is committed under the Kyoto Protocol to reduce greenhouse gas emissions between 2008 and 2012 to a level six percent below the 1990 reference value. To date, however, Canada's greenhouse gas emissions remain far above 1990 levels. Stringent short-term policy measures are needed if Canada is to meet this legally binding commitment. This paper uses a multi-region, multi-commodity static general equilibrium model to quantify the economic impacts of alternative compliance strategies for Canada in the context of climate policies undertaken by other Kyoto Parties. The numerical results confirm fears among Canadian policy makers of larger economic adjustment cost should Canada fulfill its Kyoto commitment solely through domestic action. Comprehensive use of flexible mechanisms - in particular the Clean Development Mechanism - could allow Canada to live up with its international climate policy commitment at a substantially lower economic cost

    The contradictions and unresolved tensions between economic globalization and climate change negotiations have added urgency to the climate change debate. The paper argues that the declining role of the nation state in the global economy and the increasing reach of transnational corporations throughout the world present a serious challenge to the environmental integrity and success of international environmental treaties such as the Kyoto Protocol. In particular efficacy and equity of the flexible mechanism under the Kyoto Protocol are questioned as illustrated by the patterns of Foreign Direct Investment (FDI) of the US electric power industry in the developing world. US FDI in the electric power sectors of developing countries supports continued carbon-intensive development patterns which will make the long-term goals of the Kyoto Protocol more difficult to achieve. Consequently, FDI raises questions about justifiability of giving credit to Annex I countries through CDM projects undertaken by transnational electric power corporations. 13 refs.

    Full Text Available Recently BLDC motors have been popular in various industrial applications and electric mobility. Recently BLDC motors have been popular in various industrial applications and electric mobility. In most brushless direct current (BLDC motor drives, there are three hall sensors as a position reference. Low resolution hall effect sensor is popularly used to estimate the rotor position because of its good comprehensive performance such as low cost, high reliability and sufficient precision. Various possible faults may happen in a hall effect sensor. This paper presents a fault-tolerant operation method that allows the control of a BLDC motor with one faulty hall sensor and presents the hall sensor output fault-tolerant control strategy. The situations considered are when the output from a hall sensor stays continuously at low or high levels, or a short-time pulse appears on a hall sensor signal. For fault detection, identification of a faulty signal and generating a substitute signal, this method only needs the information from the hall sensors. There are a few research work on hall effect sensor failure of BLDC motor. The conventional fault diagnosis methods are signal analysis, model based analysis and knowledge based analysis. The proposed method is signal based analysis using a compensation signal for reconfiguration and therefore fault diagnosis can be fast. The proposed method is validated to execute the simulation using PSIM.

  13. The Hall module of an exact category with duality

    OpenAIRE

    Young, Matthew B.

    2012-01-01

    We construct from a finitary exact category with duality a module over its Hall algebra, called the Hall module, encoding the first order self-dual extension structure of the category. We study in detail Hall modules arising from the representation theory of a quiver with involution. In this case we show that the Hall module is naturally a module over the specialized reduced sigma-analogue of the quantum Kac-Moody algebra attached to the quiver. For finite type quivers, we explicitly determin...

    Full Text Available The construction of an industrial park is now being prepared near the town of Nitra. The investor fixed very strict conditions for the bearing capacity and, above all, the settlement of halls and their floors. The geological conditions at the construction site are difficult: there are soft clay soils with high compressibility and low bearing capacity. A detailed analysis of soil improvement was made. Stone columns were prepared to be fitted into an approximately 5 m thick layer of soft clay. The paper shows the main steps used in the design of the stone columns.

    We describe an experiment which investigates the effect of a longitudinal electric field on the spin-polarized carriers generated by a circularly polarized light in semiconductors. Our experiment observes the effect as a Hall voltage resulting from nonequilibrium magnetization induced by the spin-carrier electrons accumulating at the transverse boundaries of the sample as a result of asymmetries in scattering for spin-up and spin-down electrons in the presence of spin-orbit interaction. It is found that the effect depends on the longitudinal electric field and doping density as well as on temperature. The results are presented by discussing the dominant spin relaxation mechanisms in semiconductors.

  16. Fractional quantization and the quantum hall effect

    Quantization with constrains is considered in a group-theoretical framework, providing a precise characterization of the set of good operators, i.e., those preserving the constrained Hilbert space, in terms of the representation of the subgroup of constraints. This machinery is applied to the quantization of the torus as symplectic manifold, obtaining that fractional quantum numbers are permitted, provided that we allow for vector valued representations. The good operators turn out to be the Wilson loops and, for certain representations of the subgroup of constraints, the modular transformations. These results are applied to the Fractional Quantum Hall Effect, where interesting implications are derived

    1984-09-01

    Quasiparticles of charge 1/m in the Fractional Quantum Hall Effect form excitons, which are collective excitations physically similar to the transverse magnetoplasma oscillations of a Wigner crystal. A variational exciton wavefunction which shows explicitly that the magnetic length is effectively longer for quasiparticles than for electrons is proposed. This wavefunction is used to estimate the dispersion relation of these excitons and the matrix elements to generate them optically out of the ground state. These quantities are then used to describe a type of nonlinear conductivity which may occur in these systems when they are relatively clean.

    Physicists have been fascinated by the behaviour of two-dimensional electron gases for the past two decades. All of these experiments were performed on inorganic semiconductor devices, most of them based on gallium arsenide. Indeed, until recently it was thought that the subtle effects that arise due to electron-electron interactions in these devices required levels of purity that could not be achieved in other material systems. However, Hendrik Schoen, Christian Kloc and Bertram Batlogg of Bell Laboratories in the US have now observed the fractional quantum Hall effect - the most dramatic signature of electron-electron interactions - in two organic semiconductors.

    The physic program at CEBAF Hall A includes several experiments using 4 GeV polarized electron beam: parity violation in electron elastic scattering from proton and {sup 4}He, electric form factor of the proton by recoil polarization, neutron spin structure function at low Q{sup 2}. Some of these experiments will need beam polarization measurement and monitoring with an accuracy close to 4%, for beam currents ranging from 100 nA to 100 microA. A project of a Compton Polarimeter that will meet these requirements is presented. It will comprise four dipoles and a symmetric cavity consisting of two identical mirrors. 1 fig., 10 refs.

    A Kubo inspired formalism is proposed to compute the longitudinal and transverse dynamical conductivities of an electron in a plane (or a gas of electrons at zero temperature) coupled to the potential vector of an external local magnetic field, with the additional coupling of the spin degree of freedom of the electron to the local magnetic field (Pauli Hamiltonian). As an example, the homogeneous magnetic field Hall conductivity is rederived. The case of the vortex at the origin is worked out in detail. A perturbative analysis is proposed for the conductivity in the random magnetic impurity problem (Poissonian vortices in the plane). (author)

    The purpose of this JTEC study is to evaluate Japan's electronic manufacturing and packaging capabilities within the context of global economic competition. To carry out this study, the JTEC panel evaluated the framework of the Japanese consumer electronics industry and various technological and organizational factors that are likely to determine who will win and lose in the marketplace. This study begins with a brief overview of the electronics industry, especially as it operates in Japan today. Succeeding chapters examine the electronics infrastructure in Japan and take an in-depth look at the central issues of product development in order to identify those parameters that will determine future directions for electronic packaging technologies.

  2. Transit-time instability in Hall thrusters

    2005-01-01

    Longitudinal waves characterized by a phase velocity of the order of the velocity of ions have been recurrently observed in Hall thruster experiments and simulations. The origin of this so-called ion transit-time instability is investigated with a simple one-dimensional fluid model of a Hall thruster discharge in which cold ions are accelerated between two electrodes within a quasineutral plasma. A short-wave asymptotics applied to linearized equations shows that plasma perturbations in such a device consist of quasineutral ion acoustic waves superimposed on a background standing wave generated by discharge current oscillations. Under adequate circumstances and, in particular, at high ionization levels, acoustic waves are amplified as they propagate, inducing strong perturbation of the ion density and velocity. Responding to the subsequent perturbation of the column resistivity, the discharge current generates a standing wave, the reflection of which sustains the generation of acoustic waves at the inlet boundary. A calculation of the frequency and growth rate of this resonance mechanism for a supersonic ion flow is proposed, which illustrates the influence of the ionization degree on their onset and the approximate scaling of the frequency with the ion transit time. Consistent with experimental reports, the traveling wave can be observed on plasma density and velocity perturbations, while the plasma potential ostensibly oscillates in phase along the discharge

  3. Cylindrical Hall Thrusters with Permanent Magnets

    The use of permanent magnets instead of electromagnet coils for low power Hall thrusters can offer a significant reduction of both the total electric power consumption and the thruster mass. Two permanent magnet versions of the miniaturized cylindrical Hall thruster (CHT) of different overall dimensions were operated in the power range of 50W-300 W. The discharge and plasma plume measurements revealed that the CHT thrusters with permanent magnets and electromagnet coils operate rather differently. In particular, the angular ion current density distribution from the permanent magnet thrusters has an unusual halo shape, with a majority of high energy ions flowing at large angles with respect to the thruster centerline. Differences in the magnetic field topology outside the thruster channel and in the vicinity of the channel exit are likely responsible for the differences in the plume characteristics measured for the CHTs with electromagnets and permanent magnets. It is shown that the presence of the reversing-direction or cusp-type magnetic field configuration inside the thruster channel without a strong axial magnetic field outside the thruster channel does not lead to the halo plasma plume from the CHT.

  4. Bimetric Theory of Fractional Quantum Hall States

    Full Text Available We present a bimetric low-energy effective theory of fractional quantum Hall (FQH states that describes the topological properties and a gapped collective excitation, known as the Girvin-Macdonald-Platzman (GMP mode. The theory consists of a topological Chern-Simons action, coupled to a symmetric rank-2 tensor, and an action à la bimetric gravity, describing the gapped dynamics of a spin-2 mode. The theory is formulated in curved ambient space and is spatially covariant, which allows us to restrict the form of the effective action and the values of phenomenological coefficients. Using bimetric theory, we calculate the projected static structure factor up to the k^{6} order in the momentum expansion. To provide further support for the theory, we derive the long-wave limit of the GMP algebra, the dispersion relation of the GMP mode, and the Hall viscosity of FQH states. The particle-hole (PH transformation of the theory takes a very simple form, making the duality between FQH states and their PH conjugates manifest. We also comment on the possible applications to fractional Chern insulators, where closely related structures arise. It is shown that the familiar FQH observables acquire a curious geometric interpretation within the bimetric formalism.

    Since the 1st generation experiment, E89-009, which was successfully carried out as a pilot experiment of (e,e(prime)K + ) hypernuclear spectroscopy at JLab Hall C in 2000, precision hypernuclear spectroscopy by the (e,e(prime)K + ) reactions made considerable progress. It has evolved to the 2nd generation experiment, E01-011, in which a newly constructed high resolution kaon spectrometer (HKS) was installed and the 'Tilt method' was adopted in order to suppress large electromagnetic background and to run with high luminosity. Preliminary high-resolution spectra of 7 ΛHe and 28 ΛAl together with that of 12 ΛB that achieved resolution better than 500 keV(FWHM) were obtained. The third generation experiment, E05-115, has completed data taking with an experimental setup combining a new splitter magnet, high resolution electron spectrometer (HES) and the HKS used in the 2nd generation experiment. The data were accumulated with targets of 7 Li, 9 Be, 10 B, 12 C and 52 Cr as well as with those of CH 2 and H 2 O for calibration. The analysis is under way with particular emphasis of determining precision absolute hypernuclear masses. In this article, hypernuclear spectroscopy program in the wide mass range at JLab Hall C that has undergone three generation is described.

    We describe the repurposing of the historic coelostat atop Caltech’s Robinson Hall for building lighting, public education and scientific research. The coelostat was originally part of George Ellery Hale’s vision of the Astrophysical Laboratory on the Caltech campus in 1932. The coelostat, designed by Russell Porter, has a 36 inch diameter primary mirror a 30 inch diameter secondary mirror and provides a 24 inch un-vignetted beam of sunlight into the building. Although constructed in the 1930s, due to wartime pressures and other projects, it was used only briefly in the 1970s and never fully realized. Recently Robinson Hall has been fully renovated to house the Ronald and Maxine Linde Center for Global Environmental Science. The coelostat operation was modernized replacing the old motors and automating all the motions. Each morning, if the weather cooperates, the dome slit opens, the mirrors configured and sunlight pours into the building. The beam of sunlight is divided into three parts. One part goes into a refracting telescope which projects a ten inch diameter of the sun onto a ground glass screen visible to the public. A second fraction is distributed to fiber optic fixtures that illuminate some of the basement rooms. The final fraction goes into two laboratories where it is used in experiments monitoring trace constituents of our atmosphere and for solar catalysis experiments. The instrument as originally conceived required at least two human operators. Now it is fully automatic and doing real science

  8. Undulator Hall Air Temperature Fault Scenarios

    International Nuclear Information System (INIS)

    Sevilla, J.

    2010-01-01

    Recent experience indicates that the LCLS undulator segments must not, at any time following tuning, be allowed to change temperature by more than about ±2.5 C or the magnetic center will irreversibly shift outside of acceptable tolerances. This vulnerability raises a concern that under fault conditions the ambient temperature in the Undulator Hall might go outside of the safe range and potentially could require removal and retuning of all the segments. In this note we estimate changes that can be expected in the Undulator Hall air temperature for three fault scenarios: (1) System-wide power failure; (2) Heating Ventilation and Air Conditioning (HVAC) system shutdown; and (3) HVAC system temperature regulation fault. We find that for either a system-wide power failure or an HVAC system shutdown (with the technical equipment left on), the short-term temperature changes of the air would be modest due to the ability of the walls and floor to act as a heat ballast. No action would be needed to protect the undulator system in the event of a system-wide power failure. Some action to adjust the heat balance, in the case of the HVAC power failure with the equipment left on, might be desirable but is not required. On the other hand, a temperature regulation failure of the HVAC system can quickly cause large excursions in air temperature and prompt action would be required to avoid damage to the undulator system.

    This bibliographical note presents a book which discusses the coexistence of the Kyoto protocol and of a regional regime within the European Union for the actual application of rules requiring mechanisms of control. The international regime implements a continuous monitoring which combines conventional techniques and more intrusive procedures. The European Community introduced a non-contentious mechanism with a large and strong law basis and sanction ability. The author assesses the ability of the monitoring system as a whole to ensure the very credibility of the Protocol. She also assesses the reliability of international and community economic tools which aim at reducing greenhouse gas emissions at a minimum cost. She also discusses the desirable evolutions of the regime of struggle against climate changes

    A project to convert the fuel of Kyoto University Research Reactor (KUR) from highly enriched uranium (HEU) to low-enriched uranium (LEU) is in progress as a part of RERTR program. Prior to the operation of LEU core, the nuclear characteristics of the core have been evaluated to confirm the safety operation. In the evaluation, nuclear parameters, such as the excess reactivity, shut down margin control rod worth, reactivity coefficients, were calculated, and they were compared with the safety limits. The results of evaluation show that the LEU core is able to satisfy the safety requirements for operation, i.e. all the parameters satisfy the safety limits. Consequently, it was confirmed that the LEU fuel core has the proper nuclear characteristics for the safety operation. (authors)

    This report proposes an analysis within the context of transition of the climate regime from the 'before-2012' regime to the 'post-2020' regime. It first gives an overview of international stakes and context (lack of ambition for climate policy, perspective of an international agreement from 2020). Then, the authors recall the history and achievements of the Kyoto protocol which is the basis of the present climate policy regime. They propose an assessment of actions performed by countries during the first period of the protocol, and focus on the present climate regime elements which are to be safeguarded. They analyse the weaknesses of the present regime, and propose possible improvements for the future post-2020 climate regime

    Considering the different relationships between the trade framework and that of the struggle against climate change, the authors address the European Union (EU) environmental strategy within the perspective of a multilateral governance of climate changes for the after-Kyoto period. After having recalled what is at stake in a border adjustment measure and outlined the difficulties of implementation of a tax-based solution at a multilateral level, the authors present the available strategies for the EU. Then, they address the strategy based on trade liberalization as incentive to the struggle against climate changes. They discuss the derogation to standard rules and finally propose a governance system between the United Nations Framework Convention on Climate Change (UNFCCC or FCCC) and the WTO

    Approaching the national Kyoto Protocol (KP) targets involves a re-definition of the actual configuration of local energy systems. This study deals with a local scale application of the IEA-MARKAL models generator, in which the anthropogenic system of Basilicata Region (Southern Italy) is investigated to support the definition of coherent long- term strategies and sound climate protection policies. A scenario by scenario analysis points out the behaviour of the optimal mix of fuels and technologies in the presence of carbon dioxide emissions constraints. Trade off curves and reduced costs analyses outline the most effective actions for contributing to the national KP targets, with particular emphasis on the interventions in Civil (Residential, Commercial and Services) and waste management sectors.

    Taylor, A.; Bramley, M.; Winfield, M.

    2005-01-01

    This study investigates government spending in the Canadian oil and gas industry within the context of greenhouse gas emission trends and Kyoto commitments. Various forms of provincial and federal government support provided between 1996 and 2002 through grants, tax expenditures, and government program expenditures for conventional oil and gas and oil sands sectors are presented. The paper contextualizes government support for oil and gas production, discusses what constitutes a subsidy, presents the methodology and approach used to establish expenditure estimates, presents the study findings and discusses expenditure estimates and puts the results into the context of other public policy work. The conclusion recommends policy changes and describes important areas for future research related to public expenditure on oil and gas production. The study concludes that while it is understood that reform or removal of environmentally harmful subsidies will not solve environmental problems alone, such actions are important in order to achieve environmental improvements and objectives. 163 refs., 24 tabs, 5 figs

    History suggests that energy policy priorities can be stratified, similar to the way Maslow structured his famous pyramid of human needs. The essay below claims that access to energy, supply security, energy costs, environmental issues and social acceptance are not subject to trade-off, but to a hierarchy that underlies the importance of satisfying lower-order needs before addressing the higher-order needs. The essay demonstrates the hierarchy with an 'energy policy needs pyramid' based on historical evidence. The pyramid is used to analyze the viability of current items of the energy policy agenda. Conclusions indicate that the Kyoto protocol might be a victim of supply insecurity, that OPEC is good for the environment and that environmentalists should make the fight against energy poverty their first priority in order to achieve their overall goals.

    I am to report on some aspects of industrial lasers in Japan. Mostly centering on the market. In Japan, the history of laser developnent is rather profound. And long. Ever since the first invention of the laser in this country in 1960. This is partly because of the fact that in Japan the spectroscopic studies of the ruby was very popular in the late 1950's. Ever since niost of the work has been done in the research laboratories of the industry, not in the universities or not in the governmental laboratories. And since that time our first activity was mainly centering on the basic research, but after that time we have the evolution of the technology. One of the features in Japan is that the activity of developement and research of laser technology from the very basic phase up to the present commercialization has been done by the same group of people, including ine. We had a national project which ended about six years ago which was sponsored by MITI. MITI is Ministry of International Trade and Industry in Japan. And because of this national project, the effect of this project had a very enlightening effect in Japan. And after that our Japanese laser market became very flourishing.

    A century ago, a woman named Mary E. Hall convinced school leaders of the need for the professional school librarian--a librarian who cultivated a love of reading, academic achievement, and independent learning skills. After graduating from New York City's Pratt Institute Library School in 1895, Hall developed her vision for the high school…

  6. What is the Hallé? | Smith | Philosophical Papers

    African Journals Online (AJOL)

    The bulk of the paper examines the difficulty of reconciling the view that the Hallé is several individuals with two prima facie plausible theses about the manner of its persistence through time. The paper is structured around some remarks made by Peter Simons about groups, and the Hallé in particular, in his Parts.

    In this paper, we focus on the connection between spin Hall effect and spin force. Here we investigate that the spin force due to spin-orbit coupling, which, in two-dimensional system, is equivalent to forces of Hirsch and Chudnovsky besides constant factors 3 and frac{3}{2} respectively, is a part of classic Anandan force, and that the spin Hall effect is an anomalous Hall effect. Furthermore, we develop the method of AC phase to derive the expression for the spin force, and note that the most basic spin Hall effect indeed originate from the AC phase and is therefore an intrinsic quantum mechanical property of spin. This method differs from approach of Berry phase in the study of anomalous Hall effect , which is the intrinsic property of the perfect crystal. On the other hand, we use an elegant skill to show that the Chudnovsky-Drude model is reasonable. Here we have improved the theoretical values of spin Hall conductivity of Chudnovsky. Compared to the theoretical values of spin Hall conductivity in the Chudnovsky-Drude model, ours are in better agreement with experimentation. Finally, we discuss the relation between spin Hall effect and fractional statistics.

    We analyze the effect of the Hall term in the magnetohydrodynamic turbulence under a strong externally supported magnetic field, seeing how this changes the energy cascade, the characteristic scales of the flow, and the dynamics of global magnitudes, with particular interest in the dissipation. Numerical simulations of freely evolving three-dimensional reduced magnetohydrodynamics are performed, for different values of the Hall parameter (the ratio of the ion skin depth to the macroscopic scale of the turbulence) controlling the impact of the Hall term. The Hall effect modifies the transfer of energy across scales, slowing down the transfer of energy from the large scales up to the Hall scale (ion skin depth) and carrying faster the energy from the Hall scale to smaller scales. The final outcome is an effective shift of the dissipation scale to larger scales but also a development of smaller scales. Current sheets (fundamental structures for energy dissipation) are affected in two ways by increasing the Hall effect, with a widening but at the same time generating an internal structure within them. In the case where the Hall term is sufficiently intense, the current sheet is fully delocalized. The effect appears to reduce impulsive effects in the flow, making it less intermittent.

    Spin Hall effects intermix spin and charge currents even in nonmagnetic materials and, therefore, ultimately may allow the use of spin transport without the need for ferromagnets. We show how spin Hall effects can be quantified by integrating Ni80Fe20|normal metal (N) bilayers into a coplanar

    In this article, I want to show how my initial encounter with the work of Stuart Hall was grounded in my reading of the later philosophy of Ludwig Wittgenstein, and was shaped by my interest in understanding the nature of racism across the three countries in which I had lived. Over the years, Hall's various writings have helped me to make sense of…

    The manifestation of the bulk quantum Hall effect on edge is the chiral anomaly. The chiral anomaly {\\it is} the underlying principle of the ``edge approach'' of quantum Hall effect. In that approach, $\\sxy$ should not be taken as the conductance derived from the space-local current-current correlation function of the pure one-dimensional edge problem.

    For the post-Kyoto period, Turkey strongly emphasizes the establishment of national emission trading system by 2015 and its integration with the EU ETS along its accession process to the EU. In this paper, we study the mechanisms of adjustment and economic welfare consequences of various ETS regimes that Turkey considers to apply by 2020, i.e. regional ETS and international trading within the EU ETS. We conduct our analysis under the current EU 20–20–20 emission target, 20%, and also under its revised version, 30%. We find that Turkey has economic gains from linking with the EU ETS under the 20% cap, in comparison to the domestic ETSs. Despite the EU's welfare loss under linkage in comparison to the case where Turkey has domestic abatement efforts, it still prefers linking as it increases economic well being compared to the case where Turkey does not abate. Under 30% cutback, Turkey has critical output loss under linkage due to high abatement burden on the EU, while the EU is better off as it passes some of its abatement burden to Turkey. Therefore, emission quotas and their allocation across the ETS and non ETS sectors become highly critical in distributing the overall economic gains from bilateral trading. - Highlights: • We conduct welfare analysis of Turkey's post-Kyoto vision on emission trading. • Welfare impacts of having Turkey in the EU ETS via EU accession are analyzed. • Analysis is done with the current EU target of 20%, and the revised target of 30%. • Welfare impacts of linkage on both regions highly depend on the emission targets. • The EU has welfare gains when Turkey engages in abatement actions

    This paper presents a scenario in which greenhouse gas emissions in Canada are brought down to half the current levels over the next 28 years, surpassing the Kyoto target and putting Canada on a course for even greater emission reductions in the long term. The rationale for this action is based on information which states that concentration of greenhouses gases in the upper atmosphere will continue to increase until emissions are brought down to about half their current levels on a global basis. Just to stop emissions from growing on a global level would require a reduction of about 50 per cent in Canada. It is noted that achieving the Kyoto targets would not stop atmospheric concentrations of greenhouse gases from continuing to rise unless they are implemented with a plan to reduce emissions even further for the long term. The design principles that were followed in coming up with a plan to achieve 50 per cent emission reductions include: an energy demand focus; efficiency; renewable energy sources; energy services that are provided by technologies that are environmentally benign; energy services provided at least cost; and diversity of energy sources. It was concluded that the key to achieving sustainable reductions in greenhouse gas emissions is on the demand side of the energy economy, suggesting there is a need for basic changes in the climate policy debate in Canada. Studies have confirmed that technological innovation and energy saving measures can meet environmental objectives while creating economic growth and employment opportunities. It was suggested that these measures could provide economic renewal in regions that are in decline. They will also reduce air pollution which is becoming a major economic and public health issue in several Canadian communities. refs., tabs., figs

    In 2008, Spain exceeded by 20.9% the CO 2 emissions allowed by the Kyoto Protocol for 2012. The financial and economic crisis has transformed these figures: as production fell so did energy demand and with it CO 2 emissions. Will the Spanish economic crisis allow Spain to fulfill its commitments? With this in mind, we have developed an extended input–output model able to forecast energy demand and compute CO 2 emissions linked to the consumption of energy goods: petroleum products, gas and coal. The results show that the crisis, and in particularly, the stagnation of the construction industry, is only one of the pillars which help to contain these emissions at −6.81%. The possibility of incorporating environmental policies, new technologies and increases in the price of crude oil in these simulations, means an even greater reduction of emissions than the impact of the crisis (−9.76%). The final result of our most pessimistic/realistic scenario is that, in 2012, Spain will exceed its CO 2 emissions, linked to the combustion of energy goods, by only 0.9%. - Highlights: ► We use an extended input–output model to forecast the evolution of CO 2 emissions. We evaluate the economic crisis impact on emissions figures (2008–2012). ► The environmental policies are introduced by considering structural trends. ► In our reference scenario, Spain exceeds Kyoto commitments only by 0.9% in 2012. ► The 16.6% emissions reduction is explained by trends (−9.8%) and crisis (−6,8%).

    CO_2 represents more than 80% of all GHG emissions and it is increasing since 1990. Energy accounts for 85% of all GHG emissions. The United States account for almost 50% of all GHG emissions from the countries of the Annex B. Russian emissions have collapsed, from 22% to 13% of total emissions from Annex B countries between 1990 and 2002. The share of the United States has increased by 6 points since 1990, the EU-15's by one point. Germany, United Kingdom, France, Italy and Spain cover 75% of total GHG emissions from the EU-15 (2002). CO_2-energy emissions in the world: 26.3 GtCO_2 in 2003. Annex B's countries account for around 60% of the world emissions; Annex B's countries which have ratified the Kyoto Protocol represent around one third of all emissions; China accounts for 16% of total emissions. China, CEI, USA and the EU-25 drive world emissions in 2003: Chinese emissions have risen by from 12% between 2002 and 2003, they account for one third of the world emissions increase. Chinese emissions have increased as much as all Annex B's countries, 25% of the world emissions increase come from the Annex B's countries which have ratified the Kyoto Protocol. CO_2-energy Emissions from the annex B's countries have been steady between 1990 and 2003: The annex B's countries which have ratified Kyoto have decreased by 10% in 2003 compared to 1990; US emissions increased sharply when those of the EU-25 decreased: +20% versus -5%; The 'hot air' of the CIS still represents 28% of 1990 CIS emissions; Meanwhile, the weight of China and India has dramatically increased: +73% and 82%. Coal is the principal emission source in the world in 2003. Since 1990, the emissions increase is principally due to coal. The energy sector (power generation essentially) accounts for more than half of total CO_2-energy emissions; the transport sector is the second largest emitter (20%). 3/4 of the CO_2-energy emissions increase is due to the energy sector, 1/4 due to the transport sector.

Result is finally the production of difference of potential (Hall voltage in address vertical in that of current and magnetic field directions. In the present work is presented a new Hall sensor exploiting the former operation. In combination with his pioneering form and using dynamic spinning current technique with an elaborate sequence, it leads to satisfactory results of produced Hall voltage with small noise in a presence of external magnetic field. Anyone can see both the spinning current and anti-Hall technique in the same sensor simultaneously.
