    1992-03-01

    The paper studies a global CO2 recycling system which combines utilization of natural energy and CO2 recovered from combustion of fossil fuel. In the model, CO2 recovered at the place of energy demand is transported to the place where energy is produced, and from the CO2 fuels are synthesized by use of solar energy and transported to the place of energy demand. Facilities worth a large amount of money are required to transmit electric power generated by the photovoltaic power generation in the desert to the fuel synthesizing plant. Therefore, production of electrolytic hydrogen by the on-site power generation and transport by pipe may be considered. As a synthetic fuel being sent back by ocean transport, methanol is considered, and synthetic methane (LNG) can also be a candidate. CO2 is recovered as liquid carbon dioxide. Possibility of CO2 recycling is dependent on development of the desert solar base, as well as depletion of fossil fuel and price increase, CO2 penalty. It has still been difficult to say which of the fuel synthesis, CO2 tanker or securing of the solar base becomes a bottleneck. Entry of recycling fuels to the market will be possible in proportion to restrictions on fossil fuels, and evaluation of the system depends almost on the rate of energy arriving from the energy-producing region. 112 refs., 70 figs. 36 tabs.

    The geothermal energy is explained together with the global environment. The global environment problem comprises ozonospheric destruction, acid rain and global warming. The important elements of measures against the global warming are rise in prediction accuracy (rise in accuracy of prediction model for which the reflection on the cloud, rainfall and evaporation, percentage of the ocean, and biosystem are taken into consideration) and technological development for the measures (high efficiency utilization of energy, reduction in CO2 production, CO2 removal, storage and recycling technology). A prediction example of the worldwide energy in 2050 indicates that the nuclear power, fossil fuel and geothermal energy occupy 50, 20 and 8%, respectively. Though poor in economical performance, the geothermal power generation will be competitive, if assumption is made of a future rise in fossil fuel cost. It is more practical than the photovoltaic power generation and wind power generation. Its CO2 emission per kWH is smaller than that of the hydraulic power generation and nuclear power generation. In the geothermal power generation, H2S largely influences the atmospheric environment. As measures against the H2S, stretford and other different processes are put in practical use. For the water quality environment, what is important is measures against the As. 24 refs., 25 figs., 2 tabs.

    The CDEX (Center for Deep Earth Exploration, JAMSTEC) is an implementing organization of a riser drilling vessel, CHIKYU ("Earth"). CHIKYU has a large capability to produce a wide variety of data, core measurement data, logging data, mud logging data, cuttings data and monitoring data in boreholes, etc. Also CDEX conducts site survey for safety drilling and publication before and after cruises. It is critical that these diverse data be managed using a unified, coherent method, and that they be organized and provided to users in an intuitive, clearly understandable way that reflects the aims and underlying philosophies of the IODP and JAMSTEC. It is crucial that these data are accessible to users through an integrated interface in which all data formats, management tools, and procedures are standardized. Meeting these goals will assure total usability for scientists, administrators, and the public, from data creation to uploading and cataloging, to end use and publication. CDEX is developing an integrated information management system, call "SIO7" (Scientific Information from 7 Oceans) for CHIKYU operation, and would like to extend to adopt various information handling systems in geosciences. The SIO7 composed of 2 major systems, J-CORES (JAMSTEC Core Systematics) and DEXIS (Deep Earth Exploration Information System) (see http://sio7.jamstec.go.jp/ for the details). J-CORES is a database system designated to manage all aspects of core data. The system is modeled on the JANUS system developed by and for ODP, but implements an extended, somewhat modified data model. The functions that support onboard and real time data input operations have also been strengthened. A variety of data visualization and visual core description functions have been added, and data loading from those applications has been automated, making the system as a whole both powerful and easy to use. On the other hand, DEXIS is developed based on the combination and integration of existing off

    For the purpose of studying how the energy supply/demand structure in Japan should be, a report on the secondary IPCC (Intergovernmental Panel on Climate Change) evaluation was analyzed. Possibilities of reducing the world CO2 emissions in association with the energy consumption were studied in the five assumed cases. Every case says that CO2 can be reduced to 1/3 of the 1990 level by 2100. In a case of the use of biomass as main fuel (1), the use of primary energy is suppressed to two times the 1990 level, and photovoltaic/wind/biomass power generation is introduced in a large quantity. Synthetic methanol and hydrogen are used for transportation and commercial/residential use fuels. There are four more assumed cases: the use of nuclear power as a substitute for renewable energy in the power generation in (1), the use of natural gas of 1.5 times that used in (1), the substitution of coal for biomass used in (1), and the assumption that the demand for primary energy in 2100 will be twice that used in (1). In Japan it is assumed that basically the nuclear power generation will be expanded, that the photovoltaic and waste power generation will be introduced in a large quantity, and that synthetic methanol and hydrogen are mainly used as transportation and commercial/residential use fuels. It is necessary, therefore, to analyze conditions under which the quantity introduction of such non-fossil energy is made possible. 11 figs., 31 tabs.

    Outlines of various energy supply/demand analytical models are surveyed. With environmental problems gathering importance, a number of models are being introduced in which energy supply/demand structures, long-term climate changes, and impacts of policy options on social economy are linked to each other. Some socioeconomic impact models cover a single country and others the whole world. They are various in type, ranging from dynamic optimization models to static balance models. Twenty-four models are chosen, and grouped into two types respectively covering Japan and the whole world from a geographical viewpoint and into three groups in view of their structures. Under an optimization model, such optimization is accomplished as economic growth maximization and energy cost minimization and so forth under given energy supply restrictions. Under a general balance type econometric model, an adjustment process in which capital and labor and production are coordinated across multiple departments is expressly stated. Under a partial balance type econometric model, a demand function for goods is given and optimum behavior such as consumption maximization is indirectly described. (NEDO)

    To investigate the energy demand and supply structure in Japan, the international trend of approaches to global warming problems and the mitigation options to global warming in the energy related sectors have been surveyed. For the United Nations Framework Convention on Climate Change, an Ad-hoc Group has discussed relevant topics after the 1st conference of the Parties. Meetings of the Group primarily focused on what objectives to set for the reduction of greenhouse gas (GHG) emissions in and in and after 2000. IPCC completed their Technical Paper in November 1996 in which technologies and measures to reduce GHG emissions and to enhance GHG sinks were analyzed and evaluated in various aspects. This Paper discusses about each sector of institutional buildings sector, transport sector, industrial sector, and energy supply sector. Especially, in the energy supply sector, promising approaches to reduce future emission include more efficient conversion of fossil fuels, switching to low-carbon fossil fuels, decarbonization of flue gas and fuels, CO2 storage, switching to nuclear energy, and switching to renewable sources of energy. 5 refs., 2 figs., 14 tabs.

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

    The paper surveyed the state of studying the measures against global warming in the third assessment report of the Intergovernmental Panel on Climate Change (IPCC) and made analyses of the trends of preventive measures for global warming in other countries, aiming at presenting data for studying the future enhancement of energy consumption efficiency in the Asia Pacific region. In the U.S., a report was taken up from Executive Office of the President which is entitled `the federal government R and D of energy for solution to problems in the 21st century.` The report made analyses of the federal government R and D of energy and at the same time recommended an increase in R and D budget and reinforcement of the organization of the Department of Energy. In Europe, the carbon tax, CO2 tax, energy tax, etc. are introduced or studied for reduction of CO2 emissions. OECD made public a report approved in May 1997 which is entitled `the environmental tax and green tax reform.` Also studied were the introduction and effects of the carbon tax aiming at reducing CO2 emissions in developing countries. More attention is being paid to economic effects predicted in case developed countries reinforce various kinds of measures for targeted reduction of greenhouse gases. 2 figs., 4 tabs.

    With respect to effects of technologies on reducing discharge amount of greenhouse gases (carbon dioxide, methane and nitrous oxide), assessments and analyses were performed on 420 techniques including energy saving technologies and new energy technologies. The energy conversion department requires further cost reduction by using such systems as LNG combined power generation using natural gas and high-efficiency coal burning thermal power generation. Requirements for paper and pulp industry include development and wider use of energy saving technologies over the entire manufacturing process, such as a direct causticizing technology and a high-performance recovery boiler. Problems in the cement industry are wider use of blast furnace cement and utilization of coal ash and tire wastes as raw fuels, and those in the iron and steel industry are energy conservation by use of coke furnace moisture adjustment and sintering cooler waste heat recovery. In the civil engineering department, introduction of heat and air insulating methods for buildings, and cogeneration operating on ceramics gas engines is expected. Use of oil substituting energy fueled cars is expected in the transportation department. 5 refs., 12 figs., 1 tab.

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

    For the study of CO{sub 2} absorption and fixation in the marine ecosystem, studies of coral reefs by RITE (Research Institute of Innovative Technology for the Earth) were subjected to discussion at the above-named workshops. It is after the elapse of a long geological time on the earth that CO2 in the atmosphere has arrived at the current level of concentration thanks to fixation and calcification by living organisms and to dissolution into the seawater. In the formation of CaCO{sub 3} that constitutes the coral skeleton, 1 mol Ca combines with 2 mol bicarbonates for the production of 1 mol CaCO{sub 3} and 1 mol CO{sub 2}. The reaction may suggests a consequential increase of CO2 in the atmosphere but such CO{sub 2} is in reality consumed by being converted into organic substances in a photosynthetic process performed by symbiotic algae. Calculation was made for the whole of Bora Bay, Miyakojima Island, and the result was that 700kg-C/day comes to be stored in the form of organic matters in the community of coral reef organisms. In a coral reef, even when it emits CO2 into the atmosphere, there is organic matter production which exceeds the lost CO{sub 2}. Coral reefs fix carbon out of the seawater at the rate of 0.42Gt-C/year, which is the aggregate of 0.3Gt organic matters and 0.12Gt CaCO{sub 3}. (NEDO)

    Nitrogen monoxide is a strong greenhouse effect gas having warming up index per molecule 300 times greater than that of CO2, and is designated as the object of reduction in the Kyoto Conference. The present preceding research discusses necessity of performing research and development works related to reducing the emission of nitrogen monoxide, and if it is necessary, places the final objective on proposition of what researches should be planned. Fiscal 1997 being the first fiscal year of the preceding research has surveyed emission amount from different emission sources, and enumerated the research and development assignments. Fiscal 1998 falling under the final fiscal year summarizes the emission amount including the future trends, surveys the feasibility of the promising technological measures through experiments, and proposed finally a research and development plan desired of implementation in the future. The proposal contains a research plan placing development of nitrogen monoxide decomposing catalysts and automobile catalysts as the main objectives. Among the domestic nitrogen monoxide generating sources, about 2/3 is the man-made generation sources, hence catalysts, if developed, may be applied to such facilities as combustion furnaces. (NEDO)

    Tire/road noise and the running performance were studied. Test were conducted using drum testing machine. If kinds and frequencies of tires are different, noise radiation characteristics are also different, and the degree of the difference are more remarkable in tires of passenger cars than those of large sized cars. There is also observed special frequency noise caused by natural vibration of tires. Noise increases when there are translots in tires, it decreases when having the translots had angles. In hydroplaning, tires which had translots installed inclinedly generate less noise. The sound absorbing rate of the pavement using dense particle asphalt-concrete mixture is low, below 0.2, but the drainage type pavement (three kinds) showed high sound absorbing rates (0.4-0.7) in each kind. Noise reduction by the drainage type pavement was seen also in the engine type noise. Further, prediction of noise propagation was possible to a certain extent using the Allard model. As to lock braking force coefficients on the wet road, there are no definite differences between roads in terms of passenger cars, but the coefficients are higher in the drainage type pavement than that using the dense particle asphalt-concrete mixture in terms of large sized cars. On the dry road, those in the use of dense particle asphalt-concrete mixture are the highest. 3 refs., 96 figs., 11 tabs.

    This paper describes environmental hormones. Hormones are directly secreted from endocrine gland into blood flow, and play an important role of the differentiation of textures of organisms, reproductive function, metabolism, and adjustment of nervous/immunity system. There are some substances with hormone and anti-hormone reactions within the body of organisms, which are discharged as chemical substances in the natural environment by the artificial production activities. These are extrinsic endocrine disrupters, i.e., environmental hormones. There are 67 kinds of doubtful substances. When the environmental hormones work on the certain reaction stage of hormones, the normal action of hormones is disturbed. Various anomalies of wild animals have been reported in the world, which are suggested to be caused by the environmental hormones. Effects are known on the health of Homo sapiens, such as malignant tumor. In the current stage, test methods are under development, by which the presence of endocrine disruption can be screened. The effects depend on the growing stages of organisms, and it is necessary to consider the effects on various generations. 20 refs., 2 figs., 4 tabs.

    Relating to the paint industry, introduction was made of environmental problem, particularly trend of the hydrocarbonexhaust regulation, and problem against the global warming gas and acid rain. Environmental pollution matter produced by the paint industry and painting industry being mainly hybrocarbon (organic solvent), the worldwide quantity of hydrocabon exhausted in the atmosphere is estimated to be annually 20 million tons, of which 18%, i.e., an annual quantity of 3.5 million tons is exhausted from the field of paint industry. The role to be played by the paint industry is important for the lowering in pollution by the hydrocarbon. Useful paints for the environmental maintenance comprise high solid paint, aqueous paint, slurry paint, powder paint and UV-hardened paint. The automobile coating is being also changed from the metallic coating to the aqueous coating. Low temperature hardening paint is used for the countermeasures against the global warming gas. For those against the acid rain, urethane hardening, hardening by the acid-epoxy group reaction, hardening by the alkoxyl froup reaction and other hardenings are developed to replace the conventional hardening by the melamine resin for heightening in acidproofness of paint film. 5 ref., 1 fig., 3 tabs.

    To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

    Forests have become drawing attention as an absorption source of carbon dioxide, a greenhouse effect gas. This paper discusses significance of forests from viewpoints of their roles as diverse ecological systems and socio-economic values. Forest is a place for living and resting of all kinds of living organisms including plants, animals and microorganisms. Living forms in forests being affluent in kinds and large in amount bring great favor to human societies. Forests play diversified roles other than biological roles in addition to largely affecting heat distribution on the ground through evapotranspiration. These roles include suppression of erosion on ground surface, alleviation of micro climate by reducing wind velocity on the ground, and disaster prevention. Forests have an aspect of supply source of production resources for societies as well as an aspect of unused lands. Efficiency of converting solar energy by plants looks inferior to that of solar cells. Biomass may be regarded as regenerative energy limited to a case where excess production is utilized. 142 refs., 56 figs., 44 tabs.

    For the inheritance of industrial technology in the past and to ensure its creative utilization, investigations were conducted into the current state of typical research information networks on the national and local level. In the process of development of industrial technology in Japan, local areas with their own peculiar traits assume very important roles. But, in such areas, important information about technology is being dissipated. As a typical network related to scientific and technological information, there exists the JOIS network of JICST, which enables the use of JICST-compiled literature and factual data base and other data bases JICST obtained from other organizations. In case of STN International of Germany, data base is a commonly owned property and each user can unlimitedly use the data bases belonging to other organizations. The Academic Information Center system offers information on books stored in university libraries and university-compiled data bases, and is equipped with the function of electronic mailing. In the Tsukuba Network the researchers living in Tsukuba Academic New Town are combined with each other by personal computer lines for performing information-related services. 41 figs., 10 tabs.

    A review was given on the theory that sea level change having occurred in the past 20,000 years has given a great impact on patterns of upheaval and subsidence of the islands of Japan. Nakada has summarized distribution of underwater remains in the western part of Kyushu and estimated values of sea surface altitude in 6000 years ago, and used this conceptional chart to propose a crust upheaval mechanism by using hydroisostasy. More specifically, this is a model that crust which has subsided due to rise in the sea level has created flows of mantle, causing upheaval of the crust in land areas. This viewpoint requires further accumulation of data and verification of the theory in areas other than the western part of Kyushu. It is important to consider the effect of sea level change also in studying processes of subsidence and sedimentation in sedimentary basins including Osaka Bay. The currently available theories use analysis solutions on stratified ground, but does not consider topographical profiles from land areas to sea areas. As this topographical effect is thought extremely important, it is necessary to develop a two-dimensional cross section analyzing method by using the finite element method. 6 refs., 3 figs.

    The environmental endocrine disruptor, or the so-called environmental hormone, is outlined. Hormones are secreted from endocrine glands in trace amounts, transported by blood, and exert influence on the target organs and distal cells, this to sustain constancy in living organisms. There are two types: peptide hormones which are rows of amino acids and steroid hormones which are composed of cholesterol. Endocrine disruptors are chemical substances discharged into the environment which, once taken into human organisms, disrupt endocrine systems, some acting like female sex hormones and others resisting male sex hormones. Many a wild animal are found affected by them. They are accumulating in human organisms too. Synthesized chemical substances such as DDT, PCB, dioxins, and alkylphenols present in the water system affect a fish by disrupting its endocrine, immunity, nerve, growth, and regeneration. Embryos and larvae are quite susceptible, easy to turn abnormal. Voices are high across the world for the study of environmental endocrine disruptors. Introduced in this report are some animal experiments, typical cases of impact on the ecosystem, and systems for detecting environmental endocrine disruptors. 36 refs., 1 tab.

    This paper describes a problem on environmental hormone. Various chemicals discharged into environment act as hormone- like or anti-hormone-like substance. Since many such chemicals act as female hormone-like substance, those are called '(exogenous) endocrine disturbing chemicals' or 'environmental hormone'. Such chemicals include already regulated toxic PCB and dioxin, and a large amount of plastic raw materials, plasticizer and surfactant with no acute toxicity. The action mechanism of endocrine disturbing chemicals is as follows. Those bond with acceptors in place of hormone, and give incorrect directions to genes. Those may cause various disorders such as reproduction anomaly, development anomaly, immune toxicity and neuro-toxicity over several ages. For wild animals, some conceivable effects are being revealed. Since living organisms have various specificities and various experiments possible for animals are impossible for mankind, many obscure points remain unsolved. This paper presents various approaches in Japan. (NEDO)

    Mulch for environmental controller of soil is divided into two types that are the best use of mulch using natural material and chemical material mulch. Stone mulch is the natural mulch and has been used in China for the cultivation of melon since about 500 years before. Plastic film mulch is used as chemical material mulch and is divided according to its purpose of use into light reflection film, light transparency suppression film, light transparent film, anti vaporization film, rain water permeation film, shock-proof film and so forth. As the weed growth was severe in case of transparent film mulch, the weed problem was solved by the development of black film or the film with weeding function prepared by mixing of polyethylene resin and weed killer. Besides, the development situation of green film mixing weed killer, light reflection type film mulch in tunnel cultivation, mulch to avoid virus diseases and non-woven cloth mulch are cited. 5 figs.

    In a study field on glass processing under microgravity environment (ME), R and D of practical advanced glasses used in a top technology field are in promotion together with basic studies on transfer phenomenon of glass melt and others. This paper presents an example of study themes on application of the remarkable effect of ME on glass to development of new materials. Glass melt with a certain composition shows extremely small surface tension and contact angle for a specific substrate. This combination shows a superfluidity under ME, and allows uniform glass coating on the surface of complicated-shape materials. Non-contact surface treatment is possible under ME by the effect of sound pressure and electrostatic force. Preparation of singular photo-functional glass is also possible by melting more than two kinds of glasses different in physical property under ME, and transferring glass melts by Marangoni convection to 3- dimensionally distribute the function into glass. Development of high-melting point glass and glass ceramic fine particles is also expected. 36 refs., 5 figs.

    For solving the problems of environmental sanitation in developing countries, assistance projects in respect of the supply of safe water and the maintenance of urine/waste water treating facility are developed by the aid organizations and civilian organizations of Japan. However, the funds, technology, capable persons, materials, etc. in developing countries are restricted in various ways, so there are a lot of cases that can not be approached by the methods in developed countries. In this paper, the appropriate technology in the environmental sanitation field in developing countries is described with practical cases. For example, there is a case that, regarding the wastewater treatment, a stabilizing pool is a safer treatment than the activated sludge process. Since the retention time in the stabilizing pool is longer than 10 days, parasitic worms in feces is settled and germs die out considerably. On the other hand, although the activated sludge process has a good removal rate of BOD, it is not an appropriate technology in developing countries because the removal rate of parasitic worms and germs are not good thus a disinfection is necessary, and additionally the electric power is rather consumed in operation. 2 refs., 4 figs., 1 tab.

    This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

    This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.

    Various physiological reaction of plants would be obstructed and troubles of their growth would be met under environmental pollution. There are also cases that the polluted materials as nutritious components are absorbed by plants. Consequently, if plant's reaction on this environmental pollution would be used, indexes of environmental pollution and environment can be improved. For examples, Ipomoea Nil and Petunia having high reaction on photochemical oxidate are widely used as index plant of air pollution. Zelkova trees and poplars planted as street trees can also greatly absorbed the polluted gas and have a function to clear air. In this paper, a diagnosis method by visualizing plant's reaction on environmental pollution by using technique of image measurement was explained. As devices of usable image measurement, a thermal camera, a solid measuring cameras, an ultrasonic camera, a multi-spectral camera and an X-ray TV camera were given. 6 refs., 4 figs., 1 tab.

    Activities to build environments where familiar living creatures live have become active among citizen`s communities and local governments. This paper describes the ways to restore waterside ecological environment using dragonfly as a parameter, and examples of the restoration in urban areas, suburban areas and mountain valleys. The importance that comes first is to establish the future image, for which ecological design must be worked on based on surveys of diverse vegetation blocks. Vegetation transition rate is very high in Japan, where grasslands of low height change to high grasslands in two or three years causing change in living creatures that live therein. This condition requires such controls as mowing, felling, and mud dredging. Building an environment where dragonflies can live needs the water quality to have BOD at 10 mg per liter or lower. The egg-laying methods of dragonflies are divided into the water surface striking and egg-laying in plant tissues. It is necessary to prepare environments that suit species, such as stalks of Zizania protruding at watersides that facilitate dragonflies to emerge, grasslands where they find the places easy to live, and adequate degrees of sunlight irradiation. Very small modification of an environment often results in a great effect. 8 figs., 1 tab.

    The catalyst creating environmental conservation and comfortable environment is generally named an `environmental catalyst (EC).` EC is roughly classified into direct and indirect type ECs. Purification catalysts for automobile exhaust gas, and catalysts for chemical production process are under investigation as direct and indirect type ECs, respectively. The catalyst was found which can remove NOx under the coexistence of oxygen by using hydrocarbon as reductant. In addition, the practical exhaust gas purification catalyst was also developed for lean-burn engines by combining noble metal catalysts with NOx absorbing materials or zeolite superior in reductant adsorbing power. {epsilon}-caprolactam as raw material of nylon 6 is synthesized from cyclohexanoneoxime through Beckmann` rearrangement reaction. Zeolite system solid catalysts using no ammonia are under investigation. An environment-friendly synthesis method using not phosgene but catalyst was proposed for production of dimethyl carbonate. How to utilize catalysts for global material circulation remains unsolved for the future study. 5 refs.

    This paper describes the following matters on the future images of the energy industries: The following two scenarios may be drawn on the future world order from the changing signs seen in three regions of the geopolitical factors, international economies, and environmental problems : One is the world of mercantilism where several blocks are formed, with the economic power of each block regarded as the ultimate purpose. Trades within a block are executed according to the market principles, while trades between the blocks are operated politically. The energy industries in this case should face incessantly new rules and market restructuring. Another scenario is a coordination maintaining world where international cooperations are preferred to the common benefits. Affluent nations determine the necessity of global systems for trade and environmental problems, while less affluent nations are forced to coordinate with these determinations. In this case, the energy industries will face directly a cost rise associated with conversions to cleaner fuels and industrial restructuring. 8 figs.

    This paper summarizes the course of development of polymer-based matrix composites (PMC) begun in the 1950's, their future problems, and prospects. Because of PMC being a petroleum product, the changing period before and after the first and second oil crises (1974-1983) has seen even a negative growth from the declined product price out of increased material cost. However, the materials have been continuing expansion in such applications year after year for two decades since then as plant, marine vessel, and housing materials. The course of their development to date has included such proliferation impeding factors as unproved reliability, high production cost, and legal regulations because of being new materials. However, the ardent technical development efforts having produced a number of products including hybrid FRP, particularly the fundamental technology development studies sponsored by the Ministry of International Trade and Industry, have improved properties and reliability and contributed largely to expanding practical applications. Sought in different functions expected in PMC in the future would be application of bionic designs, transfer from functional quality to sensitive quality, and development of material recycling techniques. 8 refs., 11 figs., 1 tab.

    Studies on the difference of solidified textures of metals and alloys under microgravity conditions from conventional ones on the earth, and the possibility of new material creation are very exciting. Features of microgravity environment in melting and solidification of metals are no thermal convection, and mass transfer caused only by diffusion. Even in alloys where the second phase molten component separates by difference in density on the earth, homogeneous textures are obtained because of no floatation and sedimentation. Melting and solidification without vessels allows to produce high-purity materials because of no invasion of impurities from vessels. No static pressure can eliminate distortions of crystals due to dead weight. No defects are observed because of no disturbance of atomic sequences. Referring to various experiments on metals under microgravity conditions, this paper outlines supercooling solidification of metal melts, solidification of single-phase alloys and multi-phase alloys such as eutectic and peritectic system ones, particle-dispersing composite materials, and the behavior of gases in molten metals. 35 refs., 8 figs., 2 tabs.

    Behavior of gas/liquid two-phase flow in tubes and behavior of air bubbles in liquid were investigated under the microgravity environment without convection by using the drop test facilities of the Japan Microgravity Center. To remove bubbles in the liquid under gravity, the strength of surface tension acting on the gas/liquid interface was made inhomogeneous. In this case, the moving velocity of bubbles on the gas/liquid interface was able to be raised up to the maximum of 2.4 mm/s. For the movement of bubbles in the horizontal direction under the condition of low relative velocity independent of the size of air bubbles in the duct, bubbles moving in the horizontal direction under 1g flowed almost linearly accompanying with the liquid flow. For the air bubble distribution in the bubble flow, where small bubbles flow in the vertical tubes, the fluid pattern of air bubble flow under 1g and {mu}g depended greatly on the initial condition of mixed bubbles. Fundamental data were obtained, as for the transportation and control of multicomponent bubbles, bubbles in the sound field, and bubbles in the liquid phase by magnetic force, and the fluid phenomena of bubbles in the subcool boiling region, a single bubble in the gradient electrical field, and bubbles in the tubes with small diameter. 47 refs., 97 figs., 8 tabs.

    As a part of the study on accelerated formation of bio- functions, analysis technology of experimental systems for in vitro evolution of protein molecules was studied. For the analysis, recognition of a fitness landscape is indispensable. Improvement of adaptive walk is possible through its analysis in an ordered space based on features of the landscape. By the last fiscal year, the knowledge of the fitness (heat-stability) landscape was obtained in the experimental system of PEP (prolyl endopeptidase) in which an adaptive walk mechanism was found to function effectively (mutated protein with a heat-stability effectively improved by adaptive walk was obtained). To obtain more general fitness landscape information, landscapes of various proteins to a fitness should be examined, and the effectiveness of approaches to efficient adaptive walk on the fitness other than a heat-stability should be clarified.

    As a part of development of intelligent material/structure systems, study was made on practical technology for rational use of energy. For resource saving and energy saving (smartening) for large and complex machines and structure systems, light-weight long-life materials/structures are indispensable. Study was thus made on the basic technology of material/structure systems equipped with realtime defect detection function, structural integrity diagnosis function and control function of noise and vibration through information processing and control by integrating composite material/structure and fiber or film sensor material/device. For development of smartening technology, sensing technology was studied to detect the interior structure of composite material/structure compacts. The basic fabrication technology of ceramic actuator materials/devices, and shape memory alloy system actuators were put into development. Smooth connection and cooperation among groups were promoted through the technical committee and research on domestic and overseas trends for forming common knowledge. (NEDO)

    Japan proposed in the Houston Summit the New Earth 21 to be carried out with technology development and technology transfer, and to make a concrete development of the project, Japan also proposed in the Tokyo Summit a TREE Plan for working out comprehensive strategies of the innovative technology development. In the CO3 Kyoto Conference in 1997, numerical targets for developed countries were determined which have legal binding force for control/reduction of greenhouse gas emissions in the term of 2008-2012. It was agreed to urge developing countries also to play a certain part in the project through the clean development. Therefore, the paper made quantitative analysis of important CO2 prevention technologies, technology transfer costs, and economical assessment by energy conservation. As a model, the DNE 21 model was upgraded and used into which CO2 prevention technologies, energy, economy and climate changes were integrated. In fiscal 1997, the following were carried out: collection of data on important CO2 prevention technologies and systems and analytical assessment using the DNE 21 model, CO2 reduction and selection of energy technology, assessment of energy system costs, construction of the unified DNE 21 model, and opening of the international workshop. 62 refs., 98 figs., 34 tabs.

    This paper introduces an energy security model intended to achieve consistency in demand and supply of energies in Japan and assure stability as a system. The model divides an energy system into segments from supply to consumption and expresses each segment in demand functions. A cross impact method is used to analyze the function. The considered structural equations involve final energy demand functions, logit share function models for fuel substitution, electric power supply blocks, interrelations among prices for fossil fuels, economic activity blocks, and cogeneration systems. Examples of evaluating the future uncertainties include interruption of oil supply, implementation of a fossil fuel consumption tax system, strengthening of regulations on nuclear power generation, and introduction of cogeneration systems. These cases were applied to the above structural equations to perform a simulation. Suggestions were given on contribution of oil substituting energies to the security, and large effect of CO2 emission tax. 18 refs., 9 figs., 7 tabs.

    A study is conducted on an energy supply infrastructure for introducing a cogeneration system into the Yumesu district, which is a key point for the development of Osaka City, so that environments suitable for the 21st century will be formed and sustained. In the study, plural heat supply systems are discussed for the district. Taken up also are the possible utilization of heat from the waste incineration plant to be constructed on the neighboring Maisu island and of hitherto-unexploited energy sources such as seawater and the sewage treatment plant whose construction is now under consideration. Findings are that every method under study achieves an energy-saving rate of 5% and that the introduction of an urban type power plant will obtain the best result marking an approximately 22% energy-saving rate when its exhaust heat is effectively utilized. The order remains the same when their environmental features are surveyed, with the urban type cogeneration system holding first place with a NOx reduction rate of 37.7%. When it comes to economy, however, the method of effectively utilizing the exhaust heat from cogeneration power plants installed at consumers' marks the best result, this attributed to the low cost of pipe laying in the district.

    Sooting field in a flame formed around a suspended droplet was visualized under microgravity using the planar laser light scattering technique. The soot concentration and the instantaneous soot amount were approximately estimated from the intensity of the scattered light using the image analysis system. The fuels employed were water-in-oil emulsions composed of n-dodecane, water and surfactant. The water content was varied from 0 to 0.2 in volume. A soot layer which was concentric with the droplet was observed inside the luminous flame. The results show the unsteadiness of the sooting behavior as well as the flame behavior. The maximum of the soot concentration is located near the inner edge of the soot layer. The time history of the instantaneous soot amount is similar to that of the instantaneous flame radius. The maximum of the soot concentration does not vary with the water content, while the soot amount decreases significantly with the water emulsification. (author)

    Procedures and systems for presenting mapping information in use in the vicinities of Sendai City and Yamagata City are described. Salinity in the groundwater grows higher from the coast toward the inland areas in the vicinity of Sendai City while there is subsidence of ground in the vicinity of Yamagata City. The ground water flow between the headwater conserving hills and mountains and the water consuming areas in the plane, as well as the spatial distribution of water permeability in the ground, relates to environmental problems. Excessive pumping, development in the peripheral regions, and wastes also pose problems in this connection. The enlargement of urban areas results in an increase in potential landslides and in the damage during earthquakes. There are faults in the crowded part of Sendai City while Yamagata City includes Mt. Zao with its eruption in the past and resultant large-scale ground failures written in the record. Urban geology conceptualizing environmental geology is a branch of geology that aims at an interdisciplinary study of these problems involving every field of geology. Environment-oriented geological charts, etc., in which geological attributes, history and prediction of damage, and data of hydrological environments are integrated, are indispensable. Their investigation, compilation, and utilization are mandatory. 2 figs., 1 tab.

    The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

    This report describes the impact assessment which is an important step for LCA. For classification of the impact assessment, the existing literature was reviewed and a skeleton for the classification was proposed. The weighting factors for nine selected impact categories, which were used to calculate environmental load point (ELP) for the valuation, were obtained for two overseas groups, i.e., students of Amsterdam University and SETAC Europe members. It was found that the former provided the similar trends to general Japanese, however that the latter gave high weighting in the global warming and depletion of ozone layer. The ELP was proposed and applied to automatic washing machine, coffee maker, waste incineration power generation system, and co-generation system. As a result, its effectiveness was demonstrated. This report also describes problems for the LCA of thermal and material recycling of PS trays. 99 refs., 96 figs., 73 tabs.

    The fatigue behavior of ceramics has been discussed on the basis of the relation between stress intensity facter (KI) and crack velocity (V). In this paper, the effect of environment on the relation between KI and V was studied on machinable ceramics (mica glass ceramics) and two kinds of glass ceramics with different grain sizes. The double torsion (DT) technique was used for the determination of the KI-V characteristics under different environments of air and ion-exchanged water. The characteristics of acoustic emission (AE) during stress corrosion cracking of mica glass ceramics was also examined. In water environment, the region II in the KI-V curve, in which crack velocity varies slowly with KI, disappeared. From this experimental fact, it was considered that at high KI, the crack velocity is encouraged by diffusion of the corrosive species to the crack and thus depended on the amount of water. SEM farc tography revealed that mica single crystals in the material caused crack arrest and deflection to occur. It is also found that AE event rate is quantitatively related to the crack velocity. AE measurement can be used in studying the crack propagation behavior of mica glass ceramics. 11 refs., 12 figs., 3 tabs.

    Feasibility of commercialization is discussed of an environmentally friendly heat supply system for the above-named district. The research centers on the configuration and optimum dimensions of heat source equipment for a large-scale cogeneration-aided district heat supply system to be selected for introduction into the district. Discussion is made about the energy efficiency and environment preserving features of a system selected for employment. A study is then conducted on a plant consisting of two high-efficiency 4800kW gas turbine cogeneration systems and heat storing water tanks. Such when introduced will contribute to the levelling-off of urban power loads and to the enhancement of power peak cut through the utilization of cogeneration system-generated power and midnight power. When the exhaust heat from the cogeneration system is fully exploited, the system will achieve an energy saving effect approximately 9% higher than that exhibited by separately functioning heat source systems. Furthermore, CO2 will be reduced by 20% or more, NOx by 45% or more, and SOx by 46% or more, as compared with separately functioning heat source systems. The conclusive evaluation is that the above-selected system will sufficiently contribute to the preservation of environments. (NEDO)

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    Effectiveness of the spectral method was confirmed for system interconnection type photovoltaic (PV) power generation systems, and PV array capacity determined in harmony with the power load was investigated. In this study, system interconnection type PV power generation systems with polycrystalline Si and amorphous Si PV cell modules were discussed. The output electric energy evaluated by the spectral method was compared with that evaluated by the conventional method only considering the cell temperature. Obtained results are as follows. For the polycrystalline Si, the differences between solar supply rates in summer evaluated by the both methods and measured value were less than 2%, which resulted in the accurate determination. For the amorphous Si, however, the difference less than 3% was obtained by the spectral method and that less than 11% was obtained by the conventional method. The spectral method provided higher accuracy. When constructing a system with large array capacity, it was found that the optimum design of PV power generation system can be performed using the spectral method with less array capacity than using the conventional method. 4 refs., 9 figs., 4 tabs.

    This paper describes a survey on an environment technology transfer information network. Based on the achievements obtained by the surveys in fiscal 1995 and 1996, the ICETT has participated as one organization constituting the APEC environment technology exchange virtual center, and begun providing information since April 1997. As the environment technology information, those items actually employed by factories and operation sites in Japan are put into a data base, and into a home page including training information centering around those contained in the data base, and examples of works done by local governments for prevention of pollution. Furthermore in fiscal 1997, a simulation software for a model process has been developed. Fiscal 1998 strengthened the data base for environment preservation technology information, investigated environment preserving model companies and summarized them including even their management aspect. Investigations were carried out in developing countries on application of cleaner technologies. Gaps far exceeding anticipation exist in every field between these developing countries and Japan. Environment protection measures applied and succeeded in the developing countries as the means to narrow the gaps were collected, and compiled as the specific examples. (NEDO)

    The history of the Hetao irrigation area can be said as the history of war in arid and semi-arid areas fought between human activity and environmental harmony. Balance of the natural water circulation is damaged as a result of agricultural production by irrigation in the Hetao irrigation area, and salt damage occurred to worsen the environment of the area. Drainage facilities are introduced as the improvement measures, but it is not easy to restore the once-damaged natural environment. Increase of salt damaged land in the area is restrained by the drainage facilities, but the incoming of salt exceeds the outgoing. The scale of the present drainage facilities is not satisfactory for restoring the salt damaged land. The salt content of the water taken in the Hetao irrigation area from the Yellow River is increasing every year influenced by the drainage from the upstream areas of the Hetao irrigation area. At the same time, untreated waste water is drained in the Yellow River. As a result, the present drainage facilities work to mitigate salt drainage in the area, but help to worsen the salt damage in downstream areas. 5 refs., 3 figs., 3 tabs.

    A rough design was performed on a floating airport. On this floating structure, environmental external force was estimated, mooring design was carried out, and discussions was given on the position retaining performance important for airport functions and behavior of the floating structure. The discussion was given on cases that the airport is surrounded and not surrounded by floating breakwaters. A floating structure which becomes super-large in size requires considerations on force due to sea level gradient as a result of a tide. Deriving flow condition changes and force acting on the floating structure simultaneously by using numerical calculations makes it possible to estimate current force given with considerations on influence of the flow conditions created by installing the floating airport. Estimation was carried out by using a zone dividing method on wave drifting force acting upon the floating airport. As a result, it was found that installing floating and permeating type breakwaters can reduce the wave drifting force acting on the floating airport. The wave drifting force working on the floating airport can be reduced by installing the floating and permeating type breakwaters to lower levels than when no such breakwaters are installed. The airport may be moored with less number of fenders when the fenders of the same type are used. 18 refs., 10 figs., 5 tabs.

    The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

    The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

    For the construction of houses that effectively utilize natural energy and impose less load on environments, an example of house building respecting environmental symbiosis is described. Reported herein are a heating system and the measurements of thermal environment in winter. In winter, the floor is heated by warm water from solar heat collectors circulating in pipes buried in downstair underfloor RC foundation. For the verification of the heating effect, comparison was made between the heater-provided southeast (SE) room and heater-unprovided northeast (NE) room, both downstairs. Warm water circulated in the underfloor pipes only in the daytime, the pipe surface recording the maximum of 32{degree}C in the daytime and the minimum of 17{degree}C early in the morning. At midnight, the SE room was warmer than the NE room by 2{degree}C. The slab surface in the SE room recorded 28{degree}C at the maximum and 17{degree}C at the minimum, but the temperature remained constant at 10{degree}C in the NE room. The rubble temperature was 17.5-20{degree}C in the SE room and approximately 11{degree}C in the NE room. It was noted that the SE room floor slab was capable of heat accumulation. The resident is a devotee of environmental symbiosis with mindset for enhancing natural energy utilization, burning an oil heater and a fireplace but intermittently. 1 ref., 12 figs., 1 tab.

    Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

    This survey arranged the status of coal utilization technology and the status of coal production, supply, etc. in Malaysia and Vietnam, examined/studied coal utilization systems in both countries, and finally assessed feasibility of introducing the environmentally friendly type coal utilization system. As a country of primary energy source which is abundant in crude oil, natural gas, hydroelectric power, coal, etc., Malaysia now depends on crude oil and natural gas for 80% of its energy, and places emphasis on exploration of natural gas and oil refining. In electric power and cement industries where coal is consumed, effectiveness and environmental issues in association with coal utilization are future subjects. In Vietnam, the north is abundant in hydroelectric power and anthracite, and the south in oil and gas resource, but the north and central districts are in a state of undevelopment. Coal is used for coal thermal power generation, cement industry, and residential/commercial fuel. In the future, effective coal utilization and environmental issues will be subjects. 16 refs., 38 figs., 75 tabs.

    The paper grasped the state of coal utilization by coal consumption field, the state of coal physical flow in Vietnam, etc., surveyed/studied a possibility of introducing the environment friendly type coal utilization system, and assessed the possibility. As to energy resources, the north is abundant in hydroelectric and coal (mainly anthracite) resources, and the south in oil and natural gas resources. Coal production in fiscal 1997 is planned to be 10 million tons. Coal preparation technique presently available is only grain size sieving. Accordingly, it is necessary to study for heightening efficiency of facilities and modernizing facilities in accordance with the introduction of the environment friendly type coal utilization technology. During the study, it is possible to propose improvement on coal processing technology (coal preparation technology). Assessment and study are made especially of the coal selection system, fine coal recovery system and waste water treatment system. For the plan on new coal-fired power plants (300MWtimes4), there is left much necessity of proposing studying models considered of the anthracite combustion technology and environmental improvement and of assessing/studying them. 60 figs., 117 tabs.

    An investigation was conducted into the systematical scheme for the introduction and promotion of environmentally friendly products mostly to the U.S., Europe and China. In the U.S., the introduction policy is given to one and all fields of the industry. The introduction policy of the U.S. has a characteristic that the introduction is left to the market principle by DSM or permit dealing, etc. except the preferential tax system and systematical finance in which the government is concerned. The policy of European countries is characterized by the idea preceding, standards or rules are first given, and the whole is pushed on to them. Accordingly, it seems that there is few atmosphere of expecting to receive the government side economic incentives from the corporate side. Legal regulations on the environment in China were prepared in a comparatively early time (1979), but the supervision of obeying the regulations and the appearance/spread of environmentally friendly product menus have just started. Accordingly, as the introduction policy on environmentally friendly products, there was found nothing valuable but the regulations. 12 refs., 3 figs., 15 tabs.

    Study was made on popularization of the proper treatment technology of industrial wastes in Asian regions. In principle, industrial wastes should be recycled in a country concerned, however, because of a difference in technology and industrial location, treatment of all industrial wastes in a country concerned is impossible. International cooperation is thus indispensable to promote proper efficient practical measures for environment. For studying the possibility of the international cooperation between Japan and Asian countries concerned for further recognition and solution of industrial waste problems, 'International Symposium on the Asian Industrial Waste Issue' have been held in Tokyo since 1997 for governmental staffs. In fiscal 1998, Malaysia was invited in addition to China, Philippines and Thailand for popularization of the proper treatment and recycling of industrial wastes in Asian regions. In every Asian countries, poor collection of discharge, treatment and disposal data is an obstacle to effective treatment. Technical cooperation and financial support by developed countries are demanded. (NEDO)

    A survey of research and development overseas and in Japan was conducted on application of metal hydride (MH) to new-functional industrial equipment such as actuators which make good use of properties of MH. An MH actuator manufactured based on a new movement principle is useful as welfare equipment in terms of its big power generated, light-weight and quiet motion. MH can raise and lower heavy matters by release and absorption of hydrogen gas. In the example where the MH actuator is used for raising and lowering the seat portion of the wheelchair, a total weight of the rise/fall portion of the wheelchair seat was found to be approximately 5 kg including that of the battery. As to welfare equipment and tools which are expectedly commercialized by using MH actuators, considered are an aid lift for taking a bath, a western-style toilet seat with a function of helping stand-up, a bedsore preventing bed, a device aiding motions of fingers/elbows, etc. Besides the welfare equipment, considered are force display for presenting force information, a small-size muscular reinforcement training device, ocean robot needing high power and low speed, etc. 72 refs., 110 figs., 28 tabs.

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

    Experiments and studies are conducted for reducing along-the-road automobile running noise. In the study of noise generation due to tire vibration, it is found that the main mechanism of noise generation on a well-drained pavement is the vibration of tires. A calculation model is built for estimating the vibration of the tire belt from the characteristics of the road surface and the tire. In the study of air column resonance in the tread groove, a method is studied of measuring fluctuations in the sound pressure in the tread groove. Measurement is conducted, and it is found that the generally accepted explanation, in which air column resonance is attributed to tread vibration generated upon collision of the tire with the road surface, needs further study for substantiation. In a model experiment, it is found that air column resonance hardly occurs on a well-drained pavement. In the study of hydroplaning, it is found that, even when the total volume of the tread longitudinal grooves is the same, the hydroplaning performance tends to improve when the groove arrangement and crown curvature are proper.

    Experiment was made on production of bio-affinity materials under a microgravity condition by using the drop experiment facility of the underground a gravity experiment center. The experiment includes fast polymerization of polymer grains, protein orientation control and protein thin film formation, organic thin film formation, O/W emulsion preparation, and crystallization of protein under a microgravity condition. In polymerization of fine pyrrole grains under the existence of fine latex grains, production of fiber polypyrrole is remarkable, and fiber growth from latex surfaces was confirmed. The obtained thin bacteriorhodopsin film shows a photoelectric response, and as the AFM observation result, it is mainly composed of violet single-layer electrodeposited films. The wetting rise of acrylic monomer at the interface between solid and liquid is largely dependent on viscosity. The oil droplet size distribution of O/W emulsion is narrower than that in ground experiment, and is close to a normal distribution. Easy imaging of products was achieved by tracing cytochrome crystals with change in turbidity. The crystallization phase diagram of black mold acid protease A, and basic data in crystallization process were obtained. (NEDO)

    A large-scale cogeneration system will be introduced into the air-front industrial complex in the Izumizawa area having large energy demand within the city of Chitose well blessed with natural environment. The system will utilize natural gas locally produced in the Tomakomai Yubarai area (the utilization produces 20% reduction effect of carbon dioxide emission even only from conversion from petroleum oil). At the same time, heat supply operation will be carried out meeting the heat demand in diversified consumer applications, such as air conditioning of ancillary facilities, hot water supply, hot bathing facilities, and snow melting. Business feasibility has been investigated and discussed. Discussions were given on gas engine, gas turbine, combined cycle, and steam jetting systems. Although the combined system was found most superior, other cases present no large difference excepting the turbine system. The system is a highly efficient energy saving facility (annually saving 3000 kiloliters of crude oil, worth for annual kerosene consumption by 1500 ordinary households in Hokkaido). It can largely reduce emission of carbon dioxide. Each case has large economic effect with the simply calculated number of years of return of investment being six to eight years. (NEDO)

    A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

    The number of winds sensed and the ratio of time sensing were introduced as sensory indexes and their relation with the comfort index in a natural ventilated room in summer was studied. A current of air is felt uncomfortable in an air conditioned room but it is felt especially comfortable in a natural-ventilated room in summer. A field investigation was made on the third floor of a building in Kyoto for 4 days in the beginning of September. The number of winds sensed in a certain time was counted and the ratio of time sensing to the certain time was measured. The wind sensed was reported dividing into 2 categories, i.e. 'wind sensing' and 'not sensing'. In this paper, the environment and temperature distribution in the room and the appropriateness of the wind sensing reports are discussed. Then the number of winds sensed and the ratio of time sensing are studied using the data obtained and it is concluded that they are effective as comfort indexes in a natural-ventilated room. 16 refs., 15 figs., 9 tabs.

    The research was conducted jointly with Europe of a catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. Reformation of mordenite and {beta}-zeolite was done by ion exchange, ion implantation, and membrane formation. A catalyst was searched for to obtain reducing agents, C5-C8 components, by decomposing light oil. Saponite, clay compound, showed by copper and silver ion exchanges approximately 50% of activity under 20,000h{sup -1}, C3H6 reducing agent, and without steam. The effect of the temperature of sintering on NOx selective reductionality of silver-carrying alumina catalyst was studied, and in sintering at 800degC, activity increased. When using conductive oxides like ruthenium oxide for electrolyte, NO decomposition selectivity increased. As to the functional layer carried above the Pd electrolyte, iron oxide and magnesium oxide increased NO decomposition selectivity. PdO and rare earth oxides forming compounds controlled variation of activity by dissociation/reoxidation of PdO. As to PdO/Gd203, the initial methane combustion activity was favorable, but there was seen deterioration with age. 271 refs., 281 figs., 58 tabs.

    This paper introduces a variable speed wind power turbine developed jointly by EPRI and US Wind Power Corporation. This wind power turbine has a wind velocity responsive construction in which generated alternating current power has the frequency vary with change in the shaft rotation speed. The specified performance calls for a cut-in of 4 m/s and cut-out of 29 m/s, wind velocity variable. The blades are made of laminated fiberglass, and the rotor has a diameter of 33 m, rotation variable. The tower height is classified to 24 m, 30 m, and 42 m. The blade pitch is controlled by a linear hydraulic cylinder, and the turbine is controlled by a microprocessor. The wind turbine has a system interconnecting control and data collecting system. Two induction three-phase generators are used. EPRI has calculated its power generation cost at 5 cents/kWh if wind blows at an annual average velocity of 16 miles per hour. This is nearly equivalent to the cost at new power plants. US Wind Power Corporation has disassembled 22 experimental models that have been in operation to investigate wear in the machines. Its economy is evaluated comparable with that for fossil fuel technologies. 1 fig.

    The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

    Studies are conducted for the development of now-unused kinds of fossil carbon resources, such as low rank coal and heavy gravity crude oil, into higher-value liquid fuel. In the preliminary treatment process, the fossil carbon resources are dried by use of supercritical carbon dioxide, when it is found that the resources are disintegrated and water is desorbed. In a low rank coal liquefaction process using the NiMo/KB (Kefjen Black) catalyst, more than 60% is converted into oil, which rate is improved by use of the dual-temperature liquefaction process. This catalyst may be recovered by separation utilizing specific gravity difference. As a low temperature gasification catalyst, the alkaline carbonate-carried carbon catalyst is very quick at the initial stage of reaction. The perovskite-carried alkaline carbonate catalyst is high in carbon oxidizing/activating efficiency at low temperatures. The silica film deposited on an alumina-coated support tube is excellent in selectivity and speed as a hydrogen separating film, and a carbonized polyimide film as a carbon dioxide separating film. For the supercritical phase adsorption/separation of chemicals not to be distilled easily, the NaY-type zeolite functions effectively. Pd/ZrO2 serving as a carbon monoxide conversion catalyst enables the recovery of more MeOH when Pd grains are smaller in diameter.

    In the subject model, a system was structured in which reproducible energy was classified into five kinds and in which recovery of CO2 from fossil fuel, processing technique and types of land utilization were generally handled together with the supply/demand of food. As a result of the analysis, it was pointed out that, although the supply of biomass energy by fuels based on agricultural waste and forestry management was hardly dependent on the structure of food supply/demand and CO2 control, the energy supply was extremely low in economical efficiency and unreliable in the future; that the CO2 recovery and its processing techniques, if the emission control was provided, would not be effective until the latter half of the next century, and accordingly, the stability of these techniques and their effects on ecosystem, for example, were necessarily investigated fully; also that, as dependency on coal is going to be high from the latter half of the next century, the techniques derived from there will be expected, and so on. The detailed preparation of energy flow was considered necessary from now on. 12 refs., 16 figs., 7 tabs.

    The new energy visions are drawn for Town of Naie, Sorachi-gun in Hokkaido, where the industrial sector (manufacturing industries) consumes more than 60% of the total energy consumption. By energy type, oil and others account for 80%. When arranged in the order of expected recoverable quantity, the new energies for the town include utilization of solar energy, photovoltaic power generation, wind power generation, and utilization of wastes, biomass energy (agricultural products) and snow energy. The basic guidelines for introduction of new energies are for health and welfare, clearing and utilization of snow, environmental education and bringing up talented persons, supporting the related entrepreneurs, and integration of new energy with promotion of energy-saving movement. The priority projects the town plans to promote include utilization of biogas and temperature-differential energy for the town's water purification center; foundation of the Naie eco-school; and drawing conceptions for utilization of underground heat, utilization of low-temperature and snow/ice energy, co-energy around the spa of Naie, and mega-solar and eco-park at the Sorachi housing complex.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) technology for development of environmental harmony type catalyst. In 1), a survey was conducted of applicability of biological surfactant to prevention measures of pollution by heavy distillate. It showed that part of the biological surfactants is reaching a stage of its being industrially produced by gene recombination bacteria, but as a whole, biosynthetic genes have hardly been elucidated. In 2), a survey of high-grade treatment technology of petroleum coke was made. It pointed out that it is necessary to develop a technology which makes the most of features of petroleum coke and allows defects. In 3), scientists and engineers of Japan and Europe searched for themes on which they can jointly study in the fields of NOx removal catalyst, up-grading of fuel, and development of catalyst combustion of fuel. 287 refs., 136 figs., 128 tabs.

    A 65-year-old woman who had complained of non-productive cough since May 1998 visited our hospital on November 5, 2000. She had been treated at another hospital with Kampo (Chinese herbal medicine), including Moku-boui-to, Bakumon-do-to, and Saiko-keishi-kankyo-to for chronic non-productive cough. Chest radiographs and CT films showed the reticular shadows that had been present in 1998, in both lower lung fields, and also demonstrated new reticular shadows in the right upper lung field and left lingular segment. Laboratory data revealed hypoxemia and pulmonary function tests revealed restrictive ventilatory disturbance, so she was admitted to our hospital on November 9, 2000. After the cessation of Kampo treatment, her symptoms disappeared, and the hypoxemia, restrictive disturbance, and reticular shadows in the chest radiograph gradually improved. Video-assisted lung biopsy specimens showed thickened alveolar walls with lymphocyte and eosinophil infiltration. A leukocyte migration test was positive for Moku-boui-to, Bakumon-do-to, and weakly positive for Saiko-keishi-kankyo-to. Although no challenge test for Kampo was performed, we diagnosed this case as interstitial pneumonia exacerbated Kampo-induced pneumonitis based on these clinical, laboratory and histological findings.

    The D/V Chikyu, committed to scientific ocean drilling since 2007, has completed thirteen IODP expeditions, and Chikyu's enhanced drilling technology gives us the means to reach deep targets, enhanced well logging, deep water riserless drilling, and state of the art laboratory. Chikyu recovered core samples from 2466 meters below sea floor (mbsf) in IODP Exp. 337, and drilled to 3058.5 mbsf in IODP Exp. 348, but these are still not the limit of Chikyu's capability. As deep as these depths are, they are just halfway to the 5200 mbsf plate boundary target for the NanTroSEIZE deep riser borehole. There are several active IODP proposals in the pipeline. Each has scientific targets requiring several thousand meters of penetration below the sea floor. Riser technology is the only way to collect samples and data from that depth. Well logging has been enhanced with the adoption of riser drilling, especially for logging-while-drilling (LWD). LWD has several advantages over wireline logging, and provides more opportunities for continuous measurements even in unstable boreholes. Because of the larger diameter of riser pipes and enhanced borehole stability, Chikyu can use several state-of-the-art downhole tools, e.g. fracture tester, fluid sampling tool, wider borehole imaging, and the latest sonic tools. These new technologies and tools can potentially expand the envelope of scientific ocean drilling. Chikyu gives us access to ultra-deep water riserless drilling. IODP Exp. 343/343T investigating the March 2011 Tohoku Oki Earthquake, explored the toe of the landward slope of the Japan Trench. This expedition reached the plate boundary fault target at more than 800 mbsf in water depths over 6900 m for logging-while-drilling, coring, and observatory installation. This deep-water drilling capability also expands the scientific ocean drilling envelope and provides access to previously unreachable targets. On top of these operational capabilities, Chikyu's onboard laboratory is

    R and D has been performed on methods to repair composite structures used in aerospace application, and on stress evaluation on repaired portions, targeting at establishment of international standardization. This paper summarizes the achievements in fiscal 2000. The current fiscal year has executed surveys on repair methods, selection of the repair methods, evaluation on the repairing processes, and compression strength evaluation on test samples given repairs. The method for repairing the sandwich-structure composite members was selected as a result surveys and discussions on published literatures. For the evaluation test on the repairing processes, specific repairing processes were established with reference to the result of surveys on the repair methods, which were applied to test samples having been given damages. In addition, discussions were given also on non-destructive inspection methods for sandwich panels. Regarding the strength test for repaired portions, a compression strength test was performed on test samples repaired by using adhesive after having been given damages, wherein data related to compression strength were obtained. Furthermore, a system was developed to analyze the scarf-like adhesive-repaired potions by using the two-dimensional finite element method model. (NEDO)

    The motor vehicle industry, which has inspired domestic production activities since the 1960's, is coming up against inevitable changes. One of the typical phenomena is that the domestic motor vehicle market is getting ripe. Since almost 80 percent of households in our country already have at least one motor vehicle and the population is going to reduce, it isn't expected that the newly car demand will increase rapidly as it did before the end of 1980's. It is strongly predicted that purchase of cars motivated mainly for replacement is going to take a leading part of domestic sales. In this paper, we calculate the impacts of extending motor vehicle's replacement cycles, as one aspect of maturation of the domestic motor vehicle market, on Japanese economy. Reduction of new car demands affects production not only in the motor vehicle industry, but also in the various industries. It is because motor vehicles are manufactured goods those need many step of production by the time of selling. Using CRIEPI's macroeconometric and input-output models, we clarified that retrenchment of car replacement would decrease 2.6 trillion yen of total industry output in 1990 constant price value added terms. The loss of output in the motor vehicle industry would be 381 billion yen, and in the retail and wholesale sector it would amount td 666 billion yen. Also, electric power industry would lose 47 billion yen's takings. Considering low economic growth since 1990, this impact could have a great influence on our prospective growing process. (author)

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

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

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

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

    Enzymatic and chemical methods were combined and methods were developed for synthesizing mucin type sugar chains and glycopeptides. The influence of sugar chain positions and structures on glycoconjugate stereo structures and physiological activities was analyzed, and glycopeptide structural activities and glycoconjugate remodelling were studied. To create an industrial advantage in a glycoprotein production system by use of zooblasts, sugar chain structure control through sugar transfase occurrence control was studied. For the production of man-adaptive sugar chains using yeast, new yeast variations were subjected to molecular breeding, and tested for the resultant improvement on productivity. Sugar chain marking and refining techniques and various responding mechanisms on the solid surface were elucidated, which enabled structure analyses using sugar chain recognition molecules such as lectins and antibodies. A database on interactions between sugar chains and sugar chain recognition molecules was constructed using the said findings. An analyzing program was also formulated tentatively. This paper also covers general surveys and studies on technologies of producing and utilizing glycoconjugates. (NEDO)

    This paper summarizes the general survey mainly conducted by FCRA (Fine Ceramics Research Association) in fiscal 1996, and the joint research results with some universities, from some R and D on synergy ceramics. Silicon nitride based ceramics expressed the same high thermal conductivity as metal by seed crystal addition, grain growth control and orientation control of sheet lamination. For its practical use, study was made on control factors of material, formation and sintering. Ca2Y2Si2O9 single crystal was prepared by float-zone method to determine its crystal structure. No volume change due to high-temperature phase transition as thermal expansion was found. In carbothermal reduction- nitridation of SiO2, addition of Si3N4 seed powder increased a reaction rate and formed uniform particles with an isotropic shape. An average particle size was dependent on the size and number of fine particles in seed powder. Addition of both Si3N4 and Fe compound could change a particle shape from a spherical grain to an elongated grain. A spherical Fe-Si metal grain was found on the tip of an elongated grain. 66 refs., 73 figs., 13 tabs.

    This paper indicates that the relationship between toxicity and biological activity of environmental hormones such as dioxin and their chemical structures may be predicted by using parameters (physical quantity) derived from the chemical hardness conception. According to this conception, softness and hardness of molecules are important in addition to electron receptivity and donation properties of molecules. Soft compounds facilitate electrons to migrate. Chlorine displacement of dioxin skeleton to 2nd, 3rd, 7th and 8th orders softens the molecules and displacement to 1st, 4th, 6th and 9th orders hardens them. The toxicity and biological activity of the environmental hormones cannot be explained only with the fit model of key-keyhole with the counterpart they act on (receptor). The softer the chemical hardness, the greater the toxicity and biological activity. Development has been made on an absolute hardness versus absolute electrical negative activity diagram to learn electron structure of molecules. This diagram indicates that the toxicity of dioxin depends more strongly on the chemical hardness than the strength of the electrical negativity, and the softer the hardness, the stronger the toxicity.

    An environmental liability act was promulgated in the European Community where the regulation on air, water, soils and foods, and the liability provisions are increasingly tightened. This paper introduces the Conditions in Germany'' for the circumstances thereabout as seen from the insurance company point of view, using an extract from the presentations at the lst International Safety Engineerings Conference. In Germany, the consciousness to the problem of Altlasten'' (inadequate disposition areas) has been heightened since about 1983. This has made the problems of soil and ground water contamination handled in more advanced ways, whereas the criterion values are not fixed but incessantly revised downwards, causing a situation embarrassing for insurance companies in how to handle liabilities of unspecified number og parties on the pollutions accumulated over many years. The new environmental act is unified under one common concept from the water quality control act to the gene technologies act. For instance in the gene technologies act enforced in July 1990, all the related operations must follow the intentions of the law makers, and are subject to statutory regulations. Liabilities must be fulfilled on any damage that even operators and scientists were not able to be aware of.

    As a part of the FY 1998 geothermal development promotion survey, the results were summed up of the environmental effect survey conducted at the Akinomiya area of Ogachi-gun, Akita prefecture. In the survey, the drilling of N9-AY-4 exploration well and short-term injection tests of N8-AY-2/N9-AY-3 were carried out in the area. The survey was made aiming at grasping the effects on hot spring/ground water level/spring water in the area. The methods used for survey were surveys of hot spring variation, ground water level variation, precipitation, rivers, all spring sources, and analyses of hot spring water/spring water in the Akinomiya area. As a result of the survey, in hot spring/ground water level/spring water, no variations were recognized which were caused by the drilling of N9-AY-3/N9-AY-4/N9-AY-5 exploration wells and short-term injection tests of N8-AY-2/N9-AY-3 exploration wells. Moreover, since few changes of spring water quality were seen also in the result of the survey of all spring sources, it was judged that the drilling and short-term injection tests of the exploration wells described above have no effects on the hot spring, ground water level and spring water in the Akinomiya area.

    Based on the basic quality equation of photovoltaic (PV) cell, a quality equation of PV module has been constructed by considering the spectral distribution of solar radiation and its intensity. A calculation method has been also proposed for determining the output from current-voltage (I-V) curves. Effectiveness of this method was examined by comparing calculated results and observed results. Amorphous Si (a-Si) and polycrystal Si PV modules were examined. By considering the environmental factors, differences of the annual output between the calculated and observed values were reduced from 2.50% to 0.95% for the a-Si PV module, and from 2.52% to 1.24% for the polycrystal Si PV module, which resulted in the reduction more than 50%. For the a-Si PV module, the environmental factor most greatly affecting the annual output was the spectral distribution of solar radiation, which was 3.86 times as large as the cell temperature, and 1.04 times as large as the intensity of solar radiation. For the polycrystal PV module, the environmental factor most greatly affecting the annual output was the cell temperature, which was 7.05 times as large as the spectral distribution of solar radiation, and 1.74 times as large as the intensity of solar radiation. 6 refs., 4 figs., 1 tab.

    To reduce SOx with coal utilization, a desulfurizer is introduced in Thailand as diffusion activities in the demonstration program. The purpose is to reduce the environmental pollutants. For this desulfurizer, lime mud mainly composed of lime stone is used as an absorber. SO2 in the flue gas is absorbed by the slurry of lime mud, to form calcium sulfite. The calcium sulfite blown in the bottom of recycling tank is oxidized by oxygen in the air, to form gypsum. The gypsum is recovered as a by-product. In this fiscal year, a feeder of lime stone, spray nozzles, and various analysis apparatuses were supplied. Supervisors for electric instrumentation/control were also dispatched as well as for main body construction, to carry out the instrumentation setting works, check of sequences, and adjustment of apparatuses. After the test operation, supervisors for the demonstration operation were dispatched up to March 1998, to conduct the cooperation works between Japan and Thailand sides. Thus, successful and successive demonstration operation was confirmed. 21 figs., 6 tabs.

    In order to realize more effective utilization of non-ferrous metal resources, joint research cooperation is made with the Republic of Kazakhstan. It is intended that valuable metals (gold, silver, copper, rare metals, and others) contained at large quantity in ore scraps generated in association with mine operation be extracted and recovered efficiently paying considerations to the environment. The treatment process consists of the following conception: raw materials such as ore scraps are leached by sulfuric acid and microorganisms to separate and recover gold and silver; the leach liquor containing valuable metals is extracted by using solvent and recovered of copper and rare metals via an electrolytic process; and the waste water is treated and discharged. Fiscal 1998 has performed studies on the wet treatment system at the site and in Japan, the gold and silver treatment, and the waste water treatment by using samples collected from the site in fiscal 1996. Based on the results of these fundamental studies, a pilot plant was built, and all of the facility fabrication was completed in fiscal 1998. Part of the facilities has been transported to the site. To drive the project forward effectively, materials and items of equipment required for the joint research were procured and transported to the country, and at the same time Kazakhstanian researchers were received in Japan for training.

    Surveys and discussions were given on business feasibility of a wide area RDF power generation system in the Kishu and Kumano living area. The discussions dealt with as wide area as transcending prefectural borders and including the southern parts of Mie and Nara Prefectures with the city of Shingu as the central part. Wastes generation amount is estimated to be about 70,000 tons at the present as wastes that can be turned into RDF, and to be decreased to 67,000 tons in 2018. The manufactured RDF has calorific power of 3500 to 4500 kcal/kg, two to three times greater than that of wastes. The RDF manufacturing facilities installed in cities, towns and villages have capacity of 30 to 50 tons a day, with that in the city of Shingu being the largest at about 78 tons a day. Transportation can be implemented most efficiently when road transportation is used. The RDF power generation system will consist of a fluid bed furnace, a plasma type ash melting furnace, and a bag filter plus activated carbon absorbing tower. The RDF manufacturing cost will be 27,900 yen per ton of wastes in the case of the city of Shingu. In terms of business profitability, the RDF power generation must find sources to pay 21,400 yen per ton of RDF even if the power sale revenue is considered. (NEDO)

    To select projects of the New Sunshine Program which is the locomotive for Japan`s research and development of energy and environmental technologies and to map out the Program`s long-term strategy, it is required to develop an effective methodology of assessing research and development themes. It is also necessary to establish the pre-assessment system which makes the assessment process more logical and which will enable the priority setting among different themes on the basis of objective and quantitative analysis. Additionally, transparency should be ensured for such a pre-assessment process through disclosure to the public and other means. The present survey aims to concretize the pre-assessment system by studying the system and techniques of an assessment system which is applicable to the research and development themes of the New Sunshine Program and is objective, quantitative and logical and which can ensure transparency and by receiving suggestions on the pre-assessment of Japan`s research and development of energies and environmental technologies through research on overseas trends of government-led research and development. 3 refs., 7 figs., 26 tabs.

    Global environmental problems are growing quite serious in developing countries, yet they are requested to properly deal with them without making light of sustainable development, for which international cooperation and diffusion of technologies for the development of environmental technologies are mandatory. Japan, utilizing what it learned from pollution within in the past and making the best use of its technologies and knowledge for environmental improvement in developing countries in Asia, has been hosting since fiscal 1997 a function of Environmental Technology Research Network in the Asia-Pacific Region function. In fiscal 1998, a fifth international symposium was convened at Science City Center at the foot of Mt. Suzuka on November 26 and 27. The central theme was the development of environmental technologies and international cooperation for developing nations, and the event attracted 180 participants from inside Japan and abroad. A number of concrete themes came out of working groups on water quality, air quality, and energy/waste, which concerned the drafting of propositions for international collaborative researches. As for researches abroad, four typical Malaysian institutes were visited. (NEDO)

    In order to reduce environmental load, such as suppression of dioxin generation in Kagoshima Prefecture having a large number of small cities, towns and villages, discussions were given on business feasibility of introducing a high-efficiency industrial wastes power generation system intended for the whole Kagoshima prefectural area. The discussions performed investigations on quantity of wastes generation by districts and kinds and the present treatment conditions, system designs, and optimization of business operation systems. Loads given to the environment in association with the system installation were also investigated (SOx, NOx and CO2 emission, and water quality contamination). The system incinerates and treats RDF, waste plastics and combustible wastes in a gasification melting furnace, and amount of dioxin in the waste gas and ash is reduced to below the regulation values. Quantity of heat obtained from the combustion is turned into high-temperature and high-pressure steam, which is utilized for power generation. As a result of the discussions on business profitability, the industrial wastes power generation system intended for the whole prefectural area was found sufficiently realizable if installed by the public organization and operated by private business organization. However, such mechanism as PFI is thought difficult in the range anticipated at the present time. (NEDO)

    Discussions were given on the new energy vision at Ueki Township in Kumamoto Prefecture. The total energy demand in Ueki Township is 898 x 10{sup 7} Kcal. of which about 44% is accounted for by the transportation department, 34.7% by the industrial department, and 21% by the consumer department. The total available regional new energy amount is estimated to be 52.1 x 10{sup 6} kWh/year, which is consisted of stockbreeding wastes energy at 44.1%, solar energy power generation at 33.2% and solar heat utilization at 22.6%. Introduction of wind energy was judged impracticable. The new energy introduction plan calls for introduction of solar energy power generation for lighting and air conditioning of the diamond shaped nursery school, the Yamamoto nursery school, the Ueki Township office building, the multi-purpose sports center, the Ueki Hospital operated by the national health insurance, the multi-purpose health and welfare center, Yoshimatsu Sports Park, and Tahara Sports Park. A subsidy institution by the local government was discussed as the proliferation plan of solar energy power generation systems to be installed in individuals' houses and enterprises, with which introduction to residential houses of about 30% was targeted by 2010.

    Discussions have been given on trends and countermeasures for resources problems from a viewpoint of wastes problems. Recycling is carried out in Japan for industrial wastes and general wastes in their own ways. However, the issue is the year-by-year increase in the quantity of products used. A conception of life cycle assessment has become used recently in environmental assessment of a certain product that its environmental load should be calculated on each of the processes of resources collection, transportation, manufacturing, sales, consumption, recycling, and disposition. The result shall then be totaled to assess the product. Experiences in the construction industry and the wastes disposition industry call for structuring a system of long-distance wastes transportation that utilizes railways and ocean vessels. Societies promoting a regeneration plant project have plans to improve model regeneration plants for construction wastes with joint efforts of construction companies. To leave beautiful environments to the next generation, it is necessary to have an awareness that rivers and roads flowing and going through a region are the properties of the people who live in the region. Environment can be preserved when everybody participates in the environment improving movement. 11 figs., 3 tabs.

    To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

    Pursuant to the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol, studies are conducted on a district cogeneration station for Radom City, Poland. Using the annual load pattern of heat supply, cogeneration will be built only for the amount that covers utilization factors not lower than a specified level, and the shortage in winter when the load is heavy due to demand for heat will be dealt with by the existing hot water boilers. Daily change in load is to be covered by a new, additional boiler which will bear 20% of the whole output. The system is a natural gas fired turbine cogenerator, and hot water is supplied by a waste heat recovery boiler. Cogeneration will cover 80% of the annual heat supply. As for heat supply capability, it is set at 72MWt with the additional boiler taken into account, and 35MWe is to be generated. Heat efficiency will increase to be higher than 80%, coal consumption will decrease, and 28,117 tons/year in terms of oil will be saved with the increase in natural gas consumption subtracted. CO2 reduction will also be as large as 206,000 tons/year, decreasing air pollutants. Provided that 4.336-billion yen for facilities are financed by Japan's environmental yen loan, Poland's National Fund, and Radom City's own fund, IRR (internal rate of return) on investment will be fairly good at 10% in 30 years of operation. Investment will be recovered in nine years and there is no problem in cash flow. (NEDO)

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    In order to achieve energy conservation in a waste water treatment plant in a brewery factories, an anaerobic treatment facility was introduced, and a fuel cell power generation facility effectively utilizing methane gas generated from the anaerobic waste water treatment plant was installed. This has resulted in large reduction in the operating number of blowers in the waste water treatment facility of activated sludge system. In addition, electric power, steam, and hot water generated from the fuel cells are effectively utilized as the factory utility. In energy conservation in an optical communication device manufacturing factory, the fan filter unit system was adopted, having been changed from the circulation air conditioner, a conventional type air conditioning system. The present system is a circulation system integrating the fan with the filter, making it possible to circulate air in the room to perform control of temperature, humidity, and dust in a clean room. Thus, the system has eliminated the circulating air conditioner, and reduced the air conditioner capacity by 42% and power consumption by 58.6% compared with those in the conventional circulation system.

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

    In the manufacturing process of semiconductors and in the high tech industry, cleaning is indispensable. At present, when regulation of the use of CFC which used to be much used has been decided on, the conversion to the use of substitutes for CFC cleaning is urgently needed. Transfer to cleaning by water/alcohol/hydrocarbon has been proceeded with, but there are a lot of problems. Out of the development of the cleaning method using supercritical fluid, the paper described the fiscal 1997 result. As to enhancement of efficiency and decrease in size of equipment, a cleaning experiment by high pressure CO2 around the critical point was conducted by integrating nozzle, ultrasonic generator and cavitation generator and adding solvent circulating system. Multi-purpose and energy saving of the equipment were also studied. To establish an analysis method for the cleaning degree, the contaminated component film of trace organic matter with a specified thickness was formed on the silicon wafer, and using the Fourier transform ultrared spectroscopy, a method to determine the film thickness was studied. For the function evaluation for precision machine parts and determination of optimum cleaning conditions, the cleaning/degreasing process of valves were compared with the conventional method. For the product manufacturing, the paper investigated and prepared the data in Japan and from abroad. 55 refs., 79 figs., 18 tabs.

    Out of the development of technology to arrange the aquatic environment using phenomena of microorganism fixation on carbon fiber soft textures, the paper stated the fiscal 1997 result. On carbon fibers in a state of swaying in water, microorganisms in water fix in an amazingly large quantity. A catalog was compiled of 58 kinds of carbon fabrics trially woven and knitted. When carbon fiber is used as activated sludge carrier, activity of microorganism lasts more than one year. Only a little amount of surplus sludge is generated. The fixed microorganisms are more active in case of carbon fiber than in case of nylon and polyester fibers. Fiber texture models of carbon fiber fixing activated sludge groups were proposed. By pump operation, the water flow inside/outside microorganism groups is being accelerated. Several new strains of bacillus carboniphilus were isolated/identified from soil and marsh. To grasp relationships of characteristics among three elements such as the state of aquatic environment, fiber, and microorganism group, the experiment was prepared. Preliminary work is conducted to derive a simple equation for facility design, and experimental directions to obtain design conditions were proposed. 6 refs., 166 figs., 47 tabs.

    In order to investigate useful protective medicines for the relief of skin injury induced by irradiation, 60 methanol extracts of Chinese traditional medicines were used in the test of protective potency on skin injury. ICR male mice at 6 weeks of age were whole-body irradiated with 1100R by using a soft X-ray generator (30 kVp, 10 mA, 190 R/min). Each methanol extract of these medicines was injected intraperitoneally into mice before or after irradiation. The degrees of skin injury were determined by a score system of skin reaction within the observation period from 21st to 40th day after irradiation. Protective potency of each medicine on skin injury was calculated from the maximum mean scores of administrated group and un-administrated group. As a result of these studies, the protective potency was detected in Unsei-in, Kumibinro-to, Keisi-syakuyaku-chimo-to, Keigai-rengyo-to, Gosyuyu-to, Koso-san, Saiko-seikan-to, Syo-kankyo-to, Syo-saiko-to, Syoma-kakkon-to, Sen-kan-meimoku-to, Zokumei-to, Sokei-kakketu-to, Bokuryo-in, Mao-to and Rikkunsi-to by intraperitoneal injection before irradiation. Of these effective medicines, only Unsei-in and Mao-to are shown to have a significant protective effect by intraperitoneal injection after irradiation. (author).

    With an objective to contribute to economic growth and global environment preservation in the Asian territories, investigations were made on histories of energy conservation and environment preserving measures used in Japanese iron and steel industry. Energy conservation in blast furnace and converter methods are based on the following actions: improvement in energy efficiency (charging moisture adjusted coals and other techniques), energy recovery (blast furnace gas expander power generation and converter gas recovery), process simplification (continuous casting, heated piece charging and other techniques), and use of alternative energies. With regard to the environment, application of such environmental preserving measures have been advanced rapidly since the 1965`s as waste gas reduction, coke furnace gas liquefaction, and reduction of dusts, soots and noise. At the same time, slag re-utilization has been moved forward. As the building material demand has increased, the use of electric furnace steel making process using scraps has increased, whose production has exceeded one-third of the crude steel production, or 32 million tons. Energy conservation in the electric furnace process consists of use of ultra high power, direct current and scrap preheating, by which unit requirement in calorific power was reduced from 1.5 million to 1.2 million kcal/t or less. The unit requirement for energy consumption for crude steel production in the Japanese iron and steel industry has reduced by 10% from 4.96 million kcal/t in fiscal 1980 to 4.44 million kcal/t in fiscal 1989. 159 refs., 84 figs., 25 tabs.

    VESPolA is a high dispersion spectro-polarimeter, mounted on the 1.3m Araki telescope at Koyama Astronomical Observatory of Kyoto Sangyo University. It employs an echelle type spectrograph and a non-ripple super-achromatic half wave plate, resulting in the highly polarimetric accuracy of δP circular polarimetry mode for this study, to VESPolA. We employ an alumina (Al2O3) slit as the new slit for the high resolution mode to minimize the instrumental polarization generated at the edge of the slit. However, because the slit width should be very narrow (= 35μm), it is technically difficult to realize the smooth slit without burr or chipping. We are trying the various processing methods, machining, etching, laser cutting, and so on. The circular polarimetry mode can be realized with a new non-ripple super-achromatic quarter wave plate and the high precision rotary unit, which is located just below the existing the half wave plate unit. We will finish the update within 2015 and start the science observations.

    2015-10-01

    In many anesthesia textbooks written in English, lidocaine, tetracaine, bupivacaine, ropivacaine, and chloroprocaine are listed as useful local anesthetics for spinal anesthesia. In contrast, T-cain is not included in these lists, even though it has been reported to be suitable for spinal anesthesia in Japan. T-cain was developed as a local anesthetic in the early 1940s by Teikoku Kagaku Sangyo Inc. in Itami, Japan, by replacing a methyl group on tetracaine (Pantocaine(®)) with an ethyl group. T-cain was clinically approved for topical use in Japan in November 1949, and a mixture of dibucaine and T-cain (Neo-Percamin S(®)) was approved for spinal use in May 1950. Simply because of a lack of foreign marketing strategy, T-cain has never attracted global attention as a local anesthetic. However, in Japan, T-cain has been used topically or intrathecally (as Neo-Percamin S(®)) for more than 60 years. Other than the side effects generally known for all local anesthetics, serious side effects have not been reported for T-cain. In fact, several articles have reported that T-cain decreases the neurotoxicity of dibucaine. In this historical review, the characteristics of T-cain and its rise to become a major spinal anesthetic in Japan are discussed. PMID:26302690

  16. Evaluation for committed effective dose due to dietary foods by the intake for Japanese adults

    International Nuclear Information System (INIS)

    Explained are the internal exposure (IE) in Japanese adults due to the ordinary intake of food and the committed effective dose (CED) derived from it, which can be the basic reference data for estimating CED at emergency like the recent Fukushima Disaster. IE lasts as long as radioactive substances exist in the body and its health risk is assessed throughout the lifetime, 50 years in adult and in children until their age of 70 years, by CED based on consideration of the physical and biological halftimes of radionuclides involved. CED (mSv) is calculated by an equation given in International Commission of Radiological Protection (ICRP) Pub. 72, using radioactivity level (Bq/kg), intake (kg/y) and age-dependent dose coefficient (mSv/Bq). Japan MEXT in its homepage (http://www.kankyo-hoshano.go.jp/) publishes the states of environmental radioactivity levels including those of daily Japanese food. The food survey of yearly changes of radioactivity level (Bq/man/day) indicates that, when compared with the level in 2009, it is two times higher in 1970s due to old in-atmospheric nuclear experiments, and is decreased gradually with a temporary peak around 1986 by Chernobyl accident. Studies on certain natural and artificial radioisotopes in 240 kinds of current food in 1989-2005 reveal that Po-210 level in fishes and shellfishes is particularly higher than others like St-90, Cs-137, Rd-226, Pb-210 and so on. CED in adults is calculated from yearly intake of foods (kg/y), their radioactivity (Bq/y) and the coefficient above, to be 0.80 mSv, and 0.98 mSv when the contribution of K-40 is taken in calculation. The proportion of the contribution in the latter estimated CED accounts for 74% (0.73 mSv) by Po-210 and for 18% (0.18 mSv) by K-40, which is conceivably derived from intake of more seafood by Japanese than other people in the world (average 0.070 and 0.17 mSv, respectively).

    IODP Expedition 319 (“Riser and Riserless Observatory-1”, NanTroSEIZE Stage 2) was the first time in IODP history that scientific riser operations were conducted. As part of this groundbreaking advance in scientific drilling, other technologies and sampling methods were also introduced: scientific mud-gas monitoring, drilling cuttings collection and analysis, MDT, and VSP (walk-away and zero-offset). Although the goals and achievements for Expedition 319 were modest, we will describe the operational portions of these technologies, and also discuss the potential and benefits of future riser drilling operations. JAMSTEC’s Center for Deep Earth Exploration (CDEX), the Japanese Implementing Organization and operator of the riser drillship Chikyu, this year performed the inaugural riser drilling expedition for IODP, as part of NanTroSEIZE Stage 2, Expedition 319, “Riser and Riserless Observatories”. Riser drilling is a typical method of drilling in industry, since it helps prevent loss of petroleum while drilling at sea, and also allows for deeper drilling depths, when compared with the usual non-riser drilling. The system aboard Chikyu is an industrial design riser system, which has just completed drilling operations in the Kumano Basin, drilling and casing a riser hole, Hole C0009A, to 1607.3 mBSF in water 2054 m BSL deep. The riser drilling system maintains a connection between the riser pipe suspended from the drillship to the sea floor blowout preventer (BOP), which makes a seal between the riser pipe and well head, and below to the cased intervals of the borehole below the seafloor. This allows the drilling mud to circulate down through the drillpipe, out the bit, and back up the casing and riser pipe to the drillship. This cools the bit, clears the borehole of cuttings (recovered aboard ship in the shale shakers) and allows real-time mud-gas monitoring. Mud weight can be more carefully controlled and adjusted, improving the quality of mudcake on the

    CRAO is a demonstrator of a compact and low-cost adaptive-optics (AO) with a double-pass lens configuration. Owing to its compact optical layout compared to conventional reflective AOs, the instrument size can be reduced to only 0.03 square meters. We plan to apply this miniaturization technique into future AOs on a variety of telescopes ranging from 1m- to 30m-class. CRAO is installed at a Nasmyth focus of the 1.3m Araki telescope at Koyama Astronomical Observatory in Kyoto Sangyo University. CRAO adopts a closed-loop single-conjugate system with wavelength coverage of 400 - 700 nm and the field of view of 30 arcsec. For low cost, we also employ commercial products on its wavefront sensor (WFS), deformable mirror (DM), and tip-tilt (TT) stage. CRAO is designed to improve the atmospheric seeing from 2.5 to 0.6arcsec under a typical condition at Koyama Astronomical Observatory with 12x12 subapertures in the WFS, 48 electrodes in the membrane DM and the control bandwidth of 200Hz. In order to examine key issues inherent in refractive optical system such as chromatic aberration, temperature aberration and ghost images, room and on-sky experiments are currently underway. CRAO has seen first light in May 2014, and we have confirmed that effects of chromatic aberration and ghost images induced by its refractive optics are negligible for at least TT correction. In this paper, we present experimental results as well as the design of optics, opto-mechanics and control system.

  19. Drilling Fluid Contamination during Riser Drilling Quantified by Chemical and Molecular Tracers

    2012-12-01

    Stringent contamination controls are essential to any type of microbiological investigation, and are particularly challenging in ocean drilling, where samples are retrieved from hundreds of meters below the seafloor. In summer 2012, Integrated Ocean Drilling Expedition 337 aboard the Japanese vessel Chikyu pioneered the use of chemical tracers in riser drilling while exploring the microbial ecosystem of coalbeds 2 km below the seafloor off Shimokita, Japan. Contamination tests involving a perfluorocarbon tracer that had been successfully used during past riserless drilling expeditions were complemented by DNA-based contamination tests. In the latter, likely microbial contaminants were targeted via quantitative polymerase chain reaction assays using newly designed, group-specific primers. Target groups included potential indicators of (a) drilling mud viscosifiers (Xanthomonas, Halomonas), (b) anthropogenic wastewater (Bifidobacterium, Blautia, Methanobrevibacter), and (c) surface seawater (SAR 11, Marine Group I Archaea). These target groups were selected based on past evidence suggesting viscosifiers, wastewater, and seawater as the main sources of microbial contamination in cores retrieved by ocean drilling. Analyses of chemical and molecular tracers are in good agreement, and indicate microorganisms associated with mud viscosifiers as the main contaminants during riser drilling. These same molecular analyses are then extended to subseafloor samples obtained during riserless drilling operations. General strategies to further reduce the risk of microbial contamination during riser and riserless drilling operations are discussed.

    A series of scientific drilling expeditions is in operation in the Nankai Trough to reveal the faulting mechanism of the magathrust earthquakes, through clarifying composition, fine structure, mechanical behavior, and environmental variables of the seismogenic faults. In the studied area, extensive seismic surveys for site characterization have been made to image detailed geometry of the fault complex in the accretionary prism as well as Vp distribution around the faults. Although these previous surveys provided invaluable information for understanding seismotectonic processes in this subduction zone, more complete knowledge is needed to be acquired to predict dynamic behavior of the faults, such as geometrical irregularities in short wavelength, Vs and seismic attenuation which are sensitive to fluid distribution in and around fault zones. It is expected that estimation of these parameters would be improved considerably by a seismic exploration using a vertical array of seismographs installed in a deep borehole (VSP: vertical seismic profiling). In July 2009, we made a VSP at one of the drilling sites located just above the rupture area of the 1994 Tonankai Earthquake (M 8.1), during the IODP Exp.319. The well site of our VSP was made by the riser drilling of D/V Chikyu. The seismic array, lowered from Chikyu into the hole, was composed of a three-component accelerometer and vertical separation of the array elements was 15.12 m. The VSP was composed of offset VSP and zero-offset VSP. In the offset VSP, a tuned airgun array towed by R/V Kairei was shot along one straight line (walk-away VSP) and another circular line (walk-around VSP) and seismic signals were recorded by an array consisting of 16 elements installed from 907 to 1,135 m in depth from seafloor. The object of the walk-away VSP is to obtain fine image of the faults using reflection arrivals with less attenuation. It is also expected to obtain spatial variation of Vs from arrival time tomography of

This study tested the relative importance of particle size and surface coating for the optimization of MRI contrast and labeling efficiency of macrophages migrating to remote inflammation sites.Materials and methods: We tested four SPIO and ultrasmall superparamagnetic iron oxide (USPIO, alkali-treated dextran magnetite (ATDM with particle sizes of 28 and 74 nm, and carboxymethyl dextran magnetite (CMDM with particle sizes of 28 and 72 nm. Mouse macrophage RAW264 cells were incubated with SPIOs and USPIOs, and the labeling efficiency of the cells was determined by the percentage of Berlin blue-stained cells and by measuring T2 relaxation times with 11.7-T MRI. We used trypan blue staining to measure cell viability.Results: Analysis of the properties of the nanoparticles revealed that ATDM-coated 74 nm particles have a lower T2 relaxation time than the others, translating into a higher ability of MRI negative contrast agent. Among the other three candidates, CMDM-coated particles showed the highest T2 relaxation time once internalized by macrophages. Regarding labeling efficiency, ATDM coating resulted in a cellular uptake higher than CMDM coating, independent of nanoparticle size. None of these particle formulations affected macrophage viability.Conclusion: This study suggests that coating is more critical than size to optimize

  2. Adequate cutoff frequency of the prefilter in quantification of regional cerebral blood flow using 123I-IMP

    International Nuclear Information System (INIS)

    The effect of cutoff frequency (CF) of the butterworth filter was studied in the quantification of regional cerebral blood flow (rCBF) by N-isopropyl-P-[123I]-iodoamphetamine (123I-IMP) auto-radiography (ARG) to determine the adequate cutoff value by comparison with XeCT/CBF. The single photon emission computed tomography (SPECT) machine was Toshiba 3-detector GCA-9300A/PI equipped with a low energy high resolution fanbeam collimator and data processor GMS-5500A/PI, on which the butterworth filter was loaded. SPECT data acquisition was performed 18-48 min after 123I-IMP injection, and the data and blood radioactivity at 10 min measured by Aloka auto-well counter ARC-300 were used for calculating rCBF (ARG/CBF) values. The CCP-II phantom for the cross calibration factor (CCF) was purchased from Sangyo Kagaku Co., Ltd. and was filled with 123I-IMP (10 kBq/mL). The CT machine was Toshiba X-vigor, and CT with Xenon gas (XeCT) was done with the products of Anzai Sogyo aspirator AZ-725 and data processor AZ-7000. XeCT data acquisition was performed by 4 min aspiration/4 min washout of the gas (Xe 30%, O2 70%) and XeCT/CBF values were calculated with the processor AZ-7000. Data were selected from 80 patients (M 46, average age 62.1 y) with chronic diseases of cerebral blood vessels, in whom ARG/CBF and XeCT/CBF tests had been conducted within a week. Examined were the relationships between CF (0.523-0.930 cycles/cm) vs CCF; CF vs ARG/CBF, where rCBF was defined to be at regions of the middle cerebral artery, thalamus and cerebral ventricle; ARG/CBF vs XeCT/CBF at CF of 0.581-0.930, where the correlation coefficient (r) and slope were evaluated for decision of the optimal CF value. Under conditions employed, CBF values varied with the CF and its optimal value was found to be 0.814 cycles/cm with a best fitted slope. (T.T.)

    The Integrated Ocean Drilling Program (IODP) Expedition 337 was the first expedition dedicated to subseafloor microbiology that used riser-drilling technology with the drilling vessel Chikyu. The drilling Site C0020 is located in a forearc basin formed by the subduction of the Pacific Plate off the Shimokita Peninsula, Japan, at a water depth of 1180 m. Primary scientific objectives during Expedition 337 were to study the relationship between the deep microbial biosphere and a series of ˜ 2 km deep subseafloor coalbeds and to explore the limits of life in the deepest horizons ever probed by scientific ocean drilling. To address these scientific objectives, we penetrated a 2.466 km deep sedimentary sequence with a series of lignite layers buried around 2 km below the seafloor. The cored sediments, as well as cuttings and logging data, showed a record of dynamically changing depositional environments in the former forearc basin off the Shimokita Peninsula during the late Oligocene and Miocene, ranging from warm-temperate coastal backswamps to a cool water continental shelf. The occurrence of small microbial populations and their methanogenic activity were confirmed down to the bottom of the hole by microbiological and biogeochemical analyses. The factors controlling the size and viability of ultra-deep microbial communities in those warm sedimentary habitats could be the increase in demand of energy and water expended on the enzymatic repair of biomolecules as a function of the burial depth. Expedition 337 provided a test ground for the use of riser-drilling technology to address geobiological and biogeochemical objectives and was therefore a crucial step toward the next phase of deep scientific ocean drilling.

    The Iheya North hydrothermal field is located in the middle Okinawa Trough, a young and actively spreading back-arc basin extending behind the Ryukyu arc-trench system in the southeastern margin of the East China Sea. In this hydrothermal field, two scientific drilling expeditions (IODP Exp 331 and SIP CK14-04) were conducted using a deep-sea drilling vessel "Chikyu," and samples from a total of 27 holes were taken. Through these expeditions, Kuroko-type volcanogenic massive sulfide deposits (VMS), hydrothermally altered volcanic rocks, and pumiceous and pelagic sediments were recovered. The recovered core provided important information about the relationship between hydrothermal activity, alteration, and ore mineralization. Whole-rock major element composition and trace element (TE) patterns of pumices were very similar to those of rhyolites in the middle Okinawa Trough (RMO). However, pumices were relatively enriched in chalcophile elements Sr and Nb, which suggest incipient mineralization. Volcanic rock generally demonstrated strong silicification and was greenish pale gray in color. Regardless of severe alteration, some rock displayed major element composition broadly similar to the RMO. Alteration was evidenced by an increase in the content of SiO2 and MgO, and decrease in Al2O3, Na2O, and K2O content. The most striking geochemical feature of altered volcanic rock was the discordance between texture and the degree of modification of TEs. Some samples showed decussate texture occupied by petal-like quartz with severe silicification, but no prominent disturbance of concentration and patterns of TEs were observed. In contrast, samples with well-preserved igneous porphyritic texture showed very low TE content and modification of TE patterns. These results suggest that the modification of texture and composition of TEs, as well as silicification, do not occur by a uniform process, but several processes. This may reflect the differences in temperature and the

    Full Text Available Scientific ocean drilling’s first in situ stress measurement was made at Site C0009A during Integrated Ocean Drilling Program (IODP Expedition 319 as part of Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE Stage 2. The Modular Formation Dynamics Tester (MDT, Schlumbergerwireline logging tool was deployed in riser Hole C0009A to measure in situ formation pore pressure, formation permeability (often reported as mobility=permeability/viscosity, and the least principal stress (S3 at several isolated depths (Saffer et al., 2009; Expedition 319 Scientists, 2010. The importance of in situ stress measurements is not only for scientific interests in active tectonic drilling, but also for geomechanical and well bore stability analyses. Certain in situ tools were not previously available for scientific ocean drilling due to the borehole diameter and open hole limits of riserless drilling. The riser-capable drillship, D/V Chikyu,now in service for IODP expeditions, allows all of the techniques available to estimate the magnitudes and orientations of 3-D stresses to be used. These techniques include downhole density logging for vertical stress, breakout and caliper log analyses for maximum horizontal stress, core-based anelastic strain recovery (ASR, used in the NanTroSEIZE expeditions in 2007–2008, and leak-off test (Lin et al., 2008 and minifrac/hydraulic fracturing (NanTroSEIZE Expedition319 in 2009. In this report, the whole operational planning process related to in situ measurements is reviewed, and lessons learned from Expedition 319 are summarized for efficient planning and testing in the future.

    A scientific drilling expedition was conducted at an active hydrothermal field on the Iheya-North Knoll by D/V Chikyu in 2014 (Expedition 907) as a part of "Next-generation Technology for Ocean Resources Survey" of the Cross-ministerial Strategic Innovation Promotion Program. During the expedition logging while drilling (LWD) was deployed to constrain the area of the fluid reservoir beneath seafloor followed by three coring holes down to 150 meter below the seafloor (mbsf). The LWD system is composed of arcVISION for resistivity and natural gamma ray measurement and TeleScope for real-time transmission of drilling parameters and arcVISION data. Five sites (C9011-15) at the Iheya-North Original Site and one site (C9016) at Aki Site were drilled with LWD. At C9012 and C9016, the arcVISION detected temperature anomaly up to 84℃ at 234 mbsf and up to 39℃ at 80 mbsf, respectively. The temperature quickly increases at that depth and it would reflect the existence of high-temperature heat source along borehole. Due to the continuous fluid circulation during drilling, the measured temperature does not indicate in-situ temperature, but it reflects the heat disturbed by the cold circulated water instead. High quality resistivity and natural gamma ray data were acquired at six sites. The log curves at Site C9016 show characteristic response; the natural gamma ray log exhibits extremely high radiation (>500 gAPI) at 7-13 and 23-31 mbsf (Zone A). In the underlying interval of 31-40 mbsf, the resistivity log exhibits extremely low value (recovery of sulfide samples.

    The marine deep biosphere remains as the least studied of all of Earth's habitats and is inadequately understood, but is extremely important to understand the impacts that microbes have on global biogeochemical cycles. Sediment samples were obtained during IODP Expedition 337 in the western Pacific Ocean, from 1,498 meters below the seafloor (mbsf; samples 6R3), 1,951-1,999 mbsf (19R1), and 2,406 mbsf (29R7). These samples were initially mixed with marine broth and cultivated under anaerobic conditions at pressure of 35 MPa (megapascal) and temperatures of 35° C, 45° C, and 55° C for 3 months on board the Chikyu. Single colonies were isolated via plating on marine broth. Then, six strains of bacteria were identified, 6R3-1, 6R3-15, 19R1-5, 29R7-12B, 29R7-12M, and 29R7-12S. The six strains were then examined for optimal growth temperature and pressure. These organisms are Gram-positive, spore-forming, facultative anaerobic piezophilic bacteria. Major fatty acids are anteiso-15:0, anteiso-17:0 and iso-15:0. Phylogenetic analysis of 16S rRNA gene sequences revealed that the isolates are closely related to Virgibacillus pantothenticus, Robinsoniella peoriensis, and Bacillus subtilis. Because of their abundance in the deep marine subsurface, these microorganisms likely play an important role in sustaining the deep microbial ecosystem and influencing biogeochemical cycles in the deep biosphere.

  9. The geological and petrological studies of the subduction boundaries and suggestion for the geological future work in Japan - How to avoid ultra-mega-earthquakes -

    The Pacific plate is surrounded by circum-Pacific active margin, along which volcanic and seismic activities are very high. Ultra-Mega-Earthquakes (=UMEs, M>9.0) are occasionally observed along the margin, where sedimentary rocks of subducting slaves contact with the accreted sedimentary rocks of subducted slaves. But, those UME have never been occured along western Pacific islandarc-trench system including Izu-Ogasawara (=Bonin)-Mariana-Yap-Palau-Philippine-Tonga-Kermadec Trenches. I assume that the geological and petrological characteristics of the subduction boundaries are very important to understand those different seismic activities. Along the above mentioned trench inner wall, especially in the southern Mariana, mantle peridotites are widely distributed. Subducting slave contacts directly with the olivine dominant mantle peridotites of subducted slave, serpentinite layer can be deposited easily under hydrous oceanic sub-bottom environment and very slippery subduction boundaries are left along the subduction zone.On the other hand, those geological evidences give us some ideas on how to avoid UMEs in the Japanese Islands along Japan Trench and Nankai Trough in future. We will be able to change artificially from normal subduction boundaries with asperity zone into slippery subduction boundaries with serpentine layer, by means of serpentine mud injection toward the subduction boundaries interior by combining the following improved drilling technologies A and B. (A) Deep Sea Drilling Vessel CHIKYU has a drilling ability to reach subduction boundary with asperity zone in the Nankai Trough. (B) Advanced drilling technology in the shale gas industry is tremendous, that is, after one vertical deep drilling, horizontal drilling towards several direction are performed, then shale gas is collected by hydraulic fracturing method. I hope that, after several generations, our posterity will be able to avoid UMEs by continuous serpentine mud injection.

    Meteorological simulations and understanding of the distribution of radioactive compounds depends on the accurate simulation of precipitation and on information regarding the timing of the emission of these radioactive pollutants from the power plant. Furthermore, three-dimensional rain drop and even fog information should be essentially important for understanding the wet deposition processes, since the initial drizzle is not measured by the tipping bucket-type raingauge. We have developed various meteorological information links (http://www.chikyu.ac.jp/akiyo/firis/) and original radar and precipitation data will be released from the page. Here we present various radar images that we have prepared for March 2011. We prepared three-dimensional radar reflectivity of the C-band radar of JMA in every 10 minutes over all Kanto Plain centered at Tokyo and Fukushima prefecture centered at Sendai. We have released images of each altitude (1km interval) for 15th - 16thand 21th March (http://sc-web.nict.go.jp/fukushima/). The vertical structure of the rainfall is almost the same at 4km with the surface and sporadic high precipitation is observed at 6 km height for 15-16th. While, generally precipitation pattern that is similar to the surface is observed at 5km height on 21th. On the other hand, an X-band radar centered at Fukushima university is also used to know more localized raindrop patterns at zenith angle of 4 degree. We prepared 10-minutes/120m mesh precipitation patterns for March 15th, 16th, 17th, 18th, 20th, 21th, 22th and 23th. Quantitative estimate is difficult from this X-band radar, but localized structure, especially for the rain-band along Nakadori (middle valley in Fukushima prefecture), that is considered to determine the highly contaminated zone, is observed with only this X-band radar in the mid-night (JST) of 15th. We will show the movie of how precipitation systems were moved at the meeting. We are preparing rain/snow amount information and fog

    Deep subseafloor environments associated with hydrocarbon reservoirs have been least explored by previous scientific drilling and hence the nature of deep subseafloor life and its ecological roles in the carbon cycle remain largely unknown. In this study, we performed cultivation of subseafloor methanogenic communities using a continuous-flow bioreactor with polyurethane sponges, called down-flow hanging sponge (DHS) reactor. The sample used for the reactor cultivation was obtained from 2 km-deep coalbeds off the Shimokita Peninsula of Japan, the northwestern Pacific, during the Integrated Ocean Drilling Program (IODP) Expedition 337 using a riser drilling technology of the drilling vessel Chikyu. The coalbed samples were incubated anaerobically in the DHS reactor at the in-situ temperature of 40°C. Synthetic seawater supplemented with a tiny amount of yeast extract, acetate, propionate and butyrate was provided into the DHS reactor. After 34 days of the bioreactor operation, a small production of methane was observed. The methane concentration was gradually increased and the stable carbon isotopic composition of methane was consistency 13C-depleted during the bioreactor operation, indicating the occurrence of microbial methanogenesis. Microscopic observation showed that the enrichment culture contained a variety of microorganisms, including methanogen-like rod-shaped cells with F420 auto-fluorescence. Interestingly, many spore-like particles were observed in the bioreactor enrichment. Phylogenetic analysis of 16S rRNA genes showed the growth of phylogenetically diverse bacteria and archaea in the DHS reactor. Predominant archaeal components were closely related to hydrogenotrophic methanogens within the genus Methanobacterium. Some predominant bacteria were related to the spore-formers within the class Clostridia, which are overall in good agreement with microscopic observations. By analyzing ion images using a nano-scale secondary ion mass spectrometry (Nano

    The vertical (downward) component of the atmospheric electric field, or potential gradient (PG) under cloud generally reflects the electric charge distribution in the cloud. The PG data at Kakioka, 150 km southwest of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) suggested that this relation can be modified when the radioactive dust was floating in the air, and the exact relation between the weather and this modification could lead to new insight in plasma physics in the wet atmosphere. Unfortunately the detailed weather data was not available above Kakioka (only the precipitation data was available). Therefore, estimation of the cloud condition during March 2011 was strongly needed. We have developed various meteorological information links (http://www.chikyu.ac.jp/akiyo/firis/) and original radar and precipitation data will be released from the page. Here we present various radar images that we have prepared for March 2011. We prepared three-dimensional radar reflectivity of the C-band radar of JMA in every 10 minutes over all Kanto Plain centered at Tokyo and Fukushima prefecture centered at Sendai. We have released images of each altitude (1km interval) for 15th - 16thand 21th March (http://sc-web.nict.go.jp/fukushima/).

    We address the fundamental questions surrounding the nature of water and chemical transport processes deep within sedimentary basin and accretionary-wedge environments. Consolidation and permeability studies conducted to 165 MPa (~10km depth) indicate that ultra-tight clay formations (10-18 m2 to10-21 m2) can substantially modify the fluids migrating through then. Pore-water extractions conducted on smectite/illite rich core samples obtained from 1-3 km depths at IODP (NanTroSEIZE, Chikyu) deep-riser drilling Site C0002, at the elevated loads required to squeeze waters from such deeply buried sediment (stresses up to 100 MPa),resulted in anomalous patterns of sequential freshening with progressive loading. More accurate laboratory investigations (both incremental loading and Constant Rate of Strain test) revealed that such freshening initiates above 20 MPa and progresses with consolidation to become greater than 20% by effective normal load of 165 MPa. Log-log plots of stress vs. hydraulic conductivity reveal that trends remain linear to elevated stresses and total porosities as low at 14%. The implications are that stress induced smectite dehydration and/or membrane filtration effects cause remarkable changes in pore water chemistry with fluid migration through deep, tight, clay-rich formations. These changes should occur in addition to any thermally induced diagenetic and clay-dehydration effects on pore water chemistry. Work is progressing to evaluate the impact of clay composition and temperature to ascertain if purely illitic compositions show similar trends and if the mass fractionation of water and other isotopes also occurs. Such studies will ascertain if the presence of smectite is a prerequisite for freshening or if membrane filtration is a major process in earth systems containing common clay minerals. The results have major implications for interpretations of mass chemical balances, pore water profiles, and the hydrologic, geochemical, and stress state

  14. Interseismic stress accumulation at the locked zone of Nankai Trough seismogenic fault off Kii Peninsula

    2011-12-01

    Since 2007, we accomplished drilling, coring and downhole measurements at 13 sites across the Nankai accretionary complex off Kii peninsula using D/V Chikyu. Although the deepest hole is well above the seismogenic fault zone, we found that the stress regime is quite variable across the accretionary prism, and their mechanism is still in discussion. An important source for such stress variation is the tectonic loading. In order to assess how much stress can possibly be accumulated around the locked zone during one seismic cycle, we conducted a simple 2D plain-strain steady-state elastic model using the finite-element method. We fixed the geometry of plate interface and prohibited a horizontal displacement at one side (above the plate interface) 200km landward from the trench. Along the plate interface except the locked zone, we allowed free slip only along the fault. The locked zone is defined at 30-100 km landward of the trench, and is assumed as 100% locked (no differential movement). The movement of downgoing lithosphere is given at the landward side boundary 200 km landward of the trench. Since we deal with the total stress accumulation within one seismic cycle, a displacement of 5 m was given as a slab pull. Young's modulus in the Kumano forearc basin (1 km thick) is set as 4 GPa taken from sonic log data at Site C0009, whereas that in the underlying domain is set at 50 GPa which would be too high for the accretionary sediment. In that case, estimated stress would be lower than provided below. Most of the tectonic stress due to 5m of plate convergence is concentrated near the downdip edge of the locked zone. The principal compressional and shear stress on the fault is larger than 5 MPa and 2 MPa, respectively. They roughly agree with the stress drop during the M8 events. These stresses along the fault, however, gradually decrease seaward to zero level. Tectonic compressional stress near the updip edge is much smaller than near downdip. At Site C0002, it is

    Chikyu Expedition 319 was the first cruise of the Integrated Ocean Drilling Program (IODP) where riser drilling was performed and real-time mud gas monitoring was conducted, because this technique requires drill-mud circulation. In contrast to conventional IODP drilling that uses drill water in combination with lost circulation, during riser drilling the drill mud returns back to the surface through a riser pipe which encases the drill pipe. The dissolved gas is extracted from returning drill mud, analyzed in real time and sampled for noble gas and stable isotopes studies. This technique has been applied in the past on scientific continental drilling projects of e.g. the International Continental Drilling Program. Expedition 319 is part of the NanTroSEIZE project, a multiexpedition, multistage IODP drilling program focused on understanding the mechanics of seismogenesis and ruptures propagation along the Nankai accretionary prism. Riser drilling was carried out on Hole C0009 that intersects the cover sediments of the Kumano Basin and probably penetrates into the accretionary prism below. Site NT2-11 is located approx. 60 km SE of the harbour of Shingu, Japan. Real-time mud gas monitoring was performed in Hole C0009 during drilling from 703 mbsf (meter below sea floor) down to 1594 mbsf and during hole enlargement from 703 mbsf to 1569 mbsf. Both datasets show similar gas distribution at depth. Gas was furthermore extracted, sampled and analyzed from drill cuttings. Drill mud gas is generally composed of air and gases that derive from the formation. The principal formation gas in drill mud from both drilling phases and in cuttings was methane. Up to 14 vol % CH4 was detected during drilling and up to 3 vol % during hole enlargement. Down to 800 mbsf and below 1280 mbsf, the methane concentration in drill mud is lower than in the surrounded interval, where methane peaks at several depths. At 1280 mbsf an unconformity is indicated from lihology, in seismic and

    The Mw 9.0 Tohoku earthquake and accompanying tsunami produced the largest slip ever recorded in an earthquake and devastated much of northern Japan on March 11, 2011. The IODP proposal for JFAST (Japan Trench Fast Drilling project) planned to drill into the Tohoku subduction zone using the research ship Chikyu, measure the fault zone physical properties, recover fault zone material, and install an observatory to directly record the temperature anomaly caused by frictional slip during the earthquake. Considering the significant technical and operational challenges related to the great water depth of ~7,000 meters, and timing constraints, the observatory needed to be both robust and simple. After frequent discussions among scientists, engineers and operators, we decided to prepare two different types of observatories. 1. Autonomous MTL (Miniature Temperature Logger) observatory. The important temperature monitoring is accomplished by 55 MTLs attached to a string (Vectran rope) which is suspended inside a 4.5" casing in the borehole. The string latches at the top of the casing to allow retrieval using the remotely operated vehicle (ROV) Kaiko operated by JAMSTEC. This observatory avoids risks associated with a thermistor cable and wellhead data logger, and increases reliability by applying proven technologies. Perhaps most importantly, this configuration allows flexibility in defining the final depth distribution of the temperature sensors. This is advantageous since information of the exact depth of the fault zone will be known only after drilling and logging. Also, the judicious placement of weak links along the string helps to minimize possible loss of the entire sensor string if it is clamped by post-seismic movements that deform the casing. 2. Telemetered PT (Pressure and Temperature) observatory. Based on the previous deployment experience of the NanTroSEIZE C0010 observatory, we prepared another system that enables long term monitoring and repeated ROV data

    The installation of LTBMS (Long Term Borehole Monitoring System) for NanTroSEIZE (Nankai Trough Seismogenic Zone Experiment) C0002 riserless hole was successfully carried out as part of IODP Expedition 332 operations by DV Chikyu in November - December 2010. The water depth of the site and penetration depth of the hole are 1937.5 m and 980 mbsf respectively. Casing (9-5/8") was set to the depth of 888 mbsf and below the CORK head, 3-1/2" tubing was deployed inside the casing as the support structure for the downhole instruments. Within the rat hole section, two pressure ports, a strain meter, a tilt meter, a broadband seismometer, geophone, and accelerometer were deployed. These seismic and geodetic sensors were set within the borehole, and coupled to the formation via cement whose physical properties (Young's modulus, Poisson's ratio, density) were adjusted to fit the formation's properties. Screen sections were set to access the pore fluids, while isolating them from the sea floor and the lower lithological units by a swellable packer, and cement, respectively. At the top of wellhead, and at the apex of the 3-1/2" tubing assembly, a CORK head was landed. The CORK head holds the pressure sensor unit (4 pressure sensors), underwater mateable data connectors (connected to the cemented sensors), and hydraulic valves to access and sample formation fluids by ROV. The major scientific features of the Hole C0002G (riserless) LTBMS are sensors monitoring multiple parameters related to seismic, geodetic and pore fluid behavior simultaneously at distinct, multiple, layers within the same borehole. The main technical difficulties in the LTBMS development are as follows: (1) Reduction method for current-induced VIV (Vortex Induced Vibration) (2) Borehole coupling for seismic and geodetic sensors (3) Anti-vibration/shock and protection method for borehole sensors/instruments (4) Attachment and protection for sensor cables and pressure lines (5) Zone isolation for multi

    ultimately on sedimentation in the deep basin. For the Miocene and older sediments the drilling, will yield information about the nature, paleoenvironments and age of deposits enabling an astronomically-tuned Neogene time scale to be refined for the period of Aquitanian through Langhian interval. 3) The Messinian extreme event represents a unique sedimentological, hydrological, oceanographic, biological and probably climatological crisis in Earth history. It is a unique case to study the impact of sea-level drop (more than 1000 m, one order of magnitude greater than Late Quaternary glaciations) on sedimentary river behavior, deltaic and evaporitic deposition and ensuing biotic crisis. Deep drilling with the R/V Chikyu is the only way to go through the complete series of evaporites in the Provence Basin, sample the initiation and evolution of the crises, the first deposits related to the lowering of sea-level on the one hand and to the salinity crisis on the other. 4) Finally, this drilling will represent the first opportunity to study the composition and functioning (metabolic processes and products, regulation of populations, etc.) of the microbial communities (bacteria, Archaea, viruses, fungi and protists) from the deep biosphere of the Mediterranean Sea. An additional and linked MSP GOLD-2 project has the objectives of recovering a unique global Pliocene records preserved on the shelf (Rabineau et al., this congress, session CL 1.6) We invite all interested scientists to join us in planning and promoting this drilling project. We are proposing an IODP Magellan workshop in Banyuls in October 2010 to bring together all interested scientists and stake-holders around these proposals and other drilling projects in the Mediterranean Sea (e.g. ICDP). Please contat us at the earliest opportunity.
