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

    In an effort to help preserve the global environment, International Center for Environmental Technology Transfer (ICETT) contributes to the solution of global environmental problems by promoting research exchanges with developing countries. As a part of this effort, ICETT hosted an environmental development researcher who visited Japan from the Institute of Environmental Research of Chulalongkorn University in Bangkok, Thailand. The invitation was extended at the request of NEDO. During the period of this investigation between September 16 and December 14, 1997, a photocatalyst was prepared and its performance was evaluated under the theme ``Application of photocatalysis to purification of atmospheric environment.`` At the same time, roadside test spots were inspected to study the practical application of optical photocatalysis. The visiting researcher also visited the National Institute for Resources and Environment to discuss with the staff of institute. This helped to deepen understandings of the state of air pollution problems confronting Japan, Europe, and North America, as well as issues related to the technologies that have been developed to solve these problems. The visiting researcher toured the RITE and examined Japan`s progress in the development of environmental control technology through joint research involving government, industry, and academia. At ICETT, the visiting researcher received training in Japan`s approaches to environmental problems in developing countries

    An application is reported of the LCA (Life Cycle Assessment) concerning reusable beer bottles (volume: 633cc). Data were collected for examination covering the four stages of natural resource acquisition, bottle production, beer filling and packaging, and distribution and consumption (with the stage of waste management being excluded because of inadequate data). Examination was made of changes brought about in the total energy consumption by varying the five parameters, that is, the number of usage of bottles, transportation distance for empty bottles, cullet ratio in glass manufacturing, transportation distance for cullet, and the bottle weight. It was found that the total energy consumption decreases with an increase in the number of usage of bottles, that an increase in the cullet ratio and a decrease in the bottle weight are effective in decreasing the total energy consumption, and that there is an energy-wise disadvantage when empty bottles are transported over a longer distance without an increase in the number of usage of bottles. 4 refs., 6 figs., 1 tab.

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

    The 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.

    This paper summarizes the global warming problem challenged by the Japan Automobile Manufacturers Association. An investigative analysis was carried out on CO2 related data. Its gists are described as follows: The rate of contribution to CO2 emission in the automotive sector is about 17%; fuel consumption improvement has long been discussed, but is in a trend of hitting the ceiling because of the needs of mounting gears for safety improvement and of vehicle upsizing; amount of fuels used is increasing year after year; the rate of the increase correlates with the economy growth; the growth of CO2 emission from automobiles would be smaller than the values given in several reports as a result of the Japanese economic growth lower than the anticipation; effects of the fuel consumption improvement are assumed to reduce CO2 emission by several percentage points in 2000; electric vehicles could reduce CO2 emission by 40% per car if nuclear power generation is partly used; fluorocarbon used in the automobile industry is for foaming, rinsing and air conditioners, with its use in the former two applications being planned to be totally abolished; and the problem thereof exists in air conditioners, for which recovery, leakage measures, and conversion to new coolants are being discussed. 12 refs., 9 figs., 1 tab.

    Mud gas logging has been commonly used in oil industry and continental scientific drilling to detect mainly hydrocarbon gases from the reservoir formation. Quick analysis of the gas provides almost real-time information which is critical to evaluate the formation and, in particular, safety of drilling operation. Furthermore, mud gas monitoring complements the lack of core or fluid samples particularly in a deep hole, and strengthen interpretations of geophysical logs. In scientific ocean drilling, on the other hand, mud gas monitoring was unavailable in riserless drilling through the history of DSDP and ODP, until riser drilling was first carried out in 2009 by D/V Chikyu. In IODP Exp 319, GFZ installed the same system with that used in continental drilling aboard Chikyu. High methane concentrations are clearly correlated with increased wood content in the cuttings. The system installation was, however, temporary and gas separator was moved during the expedition for a technical reason. In 2011, new mud gas monitoring system was installed aboard Chikyu and was used for the first time in Exp 337. The gas separator was placed on a newly branched bypass mud flow line, and the gas sample was sent to analysis unit equipped with methane carbon isotope analyzer in addition to mass spectrometer and gas chromatograph. The data from the analytical instruments is converted to depth profiles by calculating the lag effects due to mud circulation. Exp 337 was carried out from July 26 to Sep 30, 2011, at offshore Shimokita peninsula, northeast Japan, targeting deep sub-seafloor biosphere in and around coal bed. Data from the hole C0020A, which was drilled to 2466 mbsf with riser drilling, provided insights into bio-geochemical process through the depth of the hole. In this presentation, we show the design of Chikyu's new mud gas monitoring system, with preliminary data from Exp 337.

    Tasks to be fulfilled in relation to the plumbing system for reduction in environmental loads are discussed. They are the effective use of water (saving), extension of equipment life, and the adoption of materials imposing less load on the environment (ecomaterial). In the case of a hot-spring hotel M of Tottori Prefecture, water saving efforts are exerted by guiding the hot-spring water through a radiation coil placed in a fall-provided pond for temperature reduction. In the case of a hot-spring hotel S of Iwate Prefecture, for the effective utilization of hot-spring water gushing out in abundance, a heat exchanger is installed for exchanging heat between the hot spring water and city water. The thus-warmed city water is fed to room baths and to taps in the public bath, and the hot water overflowing the public bath is utilized as the heat source for a wastewater heat recovery heat pump before being discharged into the river. As for equipment life extension, there is for instance the case of vinyl chloride pipe which has been in use for the purpose of cost reduction. Since it is expected that the life of plastic pipes will be more than 10-20 years longer than that of metal pipes, it has become necessary to consider the issue of ecomaterials. 5 refs., 4 figs., 5 tabs.

    Discussion is made on the recycling of resources which is one the very important problems for the global environment and human activity. In consideration of the limited natural resources and utilization by the human race of the resources for long, recycling of resources'' for saving resources is extremely important. The scale of the waste treatment industry in Japan is estimated to be between 4 to 5 trillion yen which exceeds 1% of the GNP with the trend of increase year by year, and the industrial waste treatment industry is taking root in Japan. Recycling'' can be grouped in three methods, i.e. recovery of materials, conversion of materials, and conversion of energy. The primary object of recycling is to spare resources and save energy. Recycling is of deep significance from the viewpoint of energy saving. There is a big merit in the conservation of dumping sites. Making best use of the useful secondary resources in the wastes is directly connected with the solution to the problems of prolongation of resources'' and conservation of global environment'' with which the human race is now confronted. 7 refs., 7 figs., 2 tabs.

    This is a report on the global warming issue made by the Institute of Energy Economics entrusted with the survey by NEDO. Written below are titles of the chapters in the report: 1. Outline of global warming problems and developments of international conferences. 2. Factor analysis of past CO{sub 2} emissions. 3. Measures to limit global warming. 4. Limitation measures for global warming and prospects for CO{sub 2} emissions. Analyses are made by country, by region or globally. For example, in order to establish measures to solve the global warming problem as an international issue, it is most important to establish the target criteria to control emission of greenhouse gases like CO{sub 2}. Namely, most important is to determine the criteria and partial charge of each country. These will exert a large effect on each economic activity. There are big differences among countries in the gas emission up to the present from the past. Effects of the gas emission are also different among countries. Moreover, countries are different in their development stages. All these differences are an important subject in judging international fairness. 91 refs., 91 tabs.

    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.

    In order to construct the information network system for a research of innovative technology for the earth, a prototype has been made. To draw necessary functions for the information network system, an information flow in a general research work is analyzed to classify it based on the functions. The information collecting function, information accumulating and sharing function, special information system for research, information providing function, and communication function of the net work correspond to the collecting information, accumulating information, being engaged in research, providing information, and communication of researcher`s actions, respectively. The services on network system supposed from these functions are the homepage search mailing list, intranet service, special information system for research, WWW Internet broadcasting, and BBS/news/conference tool, respectively. It was found that latest Internet technology enabled to construct easily controlled system environment for users and WWW would develop as a standard communication tool. 2 refs., 26 figs., 27 tabs.

    This paper makes analyses of what policy and technological option each advanced industrial country thinks to take as measures for the global warming problem, at the same time clarifying the trends in international meetings. Analyses are also made of attitudes of developing countries and the international cooperation problem. Among the problems on global warming, an emphasis is placed on introduction of energy saving and what role the development of new energy plays. A positive group consisting mostly of West European countries is advocating a `Go Quickly` approach, while the US representing a prudent group is developing a `Go Slowly` approach. The US is considering afforestation which is useful to absorb CO{sub 2} and methane recovery as technological options. West European countries regard CO{sub 2} fixation as an important option. USSR, East European and developing countries consider that the most feasible and successful CO{sub 2} measures are energy saving/improvement of energy efficiency and forest administration/afforestation. 43 figs., 78 tabs.

    An analysis on the factors related to carbon dioxide (CO {sub 2} ) emissions in the past, was conducted. Then, an option menu of measures to prevent global warming including alternative energy-related ones, was discussed. In the industrial world, great contribution to increasing CO {sub 2} emissions made by the economic growth factor has been offset by CO {sub 2} reductions resulting from energy conservation and fuel switching. The Soviet/East European and the developing worlds register increasing CO {sub 2} emissions. Different countries have different views of the key option to be taken in limiting CO {sub 2} emissions. Each of currently available CO {sub 2} reduction measures has its own difficulties, and none of them is able to provide a powerful means to solve global warming problems single-handedly. To begin with, it is essential to produce time to find truly effective limiting and/or adapting measures by slowing global warming as much as possible through comprehensive strategies which call for every possible effort in all the sectors. 83 figs., 92 tabs.

    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.

    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.

    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.

    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.

    Telework is an effective work style using information communication without commutation, and ITS is an integrated traffic system such as advanced navigation. Effects of the CO2 emission reduction by these information communication systems were calculated as a trial. Reduction of CO2 4.06 million ton was obtained, which is equivalent to about 7% of the reduction target 56.5 million ton in Japan by 2010. For the items, were obtained 1.29 million ton (MT) by telework, 1.1 MT by ITS, 0.53 MT by the reduction of paper consumption/rejection using LAN, and 0.5 MT by the alternation of movements for international business using Internet (reduction of overseas official trips). In addition, were obtained 0.36 MT by the energy saving with enhanced efficiency of office environment using advanced information communication such as building management information systems, 0.25 MT by the electronic publication and newspaper for the reduction of paper consumption/rejection using electronic media such as CD-ROM, and 0.03 MT by the remote education and at-home education systems. The trial calculations were conducted only for these seven systems, and only for the direct effects using these systems. Accordingly, the result is only a part of the whole. These systems promote to realize a society with reduced environmental loads. 2 tabs.

    By means of introduction of the drilling vessel 'CHIKYU', riser drilling operations using mud fluid will be carried out in NanTroSEIZE Stage 2 for the first time as an oceanic scientific-drilling. For determining drilling operation parameter such as a mud density, a downhole experiment, leak-off test (LOT) or extended leak-off test (XLOT), is going to be implemented next to casing and cementing at each casing shoe during the drilling process. Data of the downhole experiment aimed for operation can also be used for an important scientific application to obtain in-situ stress information which is necessary for various cases of scientific drillings such as seismogenic zone drillings etc. In order to examine feasibility of the application of the LOT or XLOT data, we analyzed an example of XLOT conducted by the riser vessel CHIKYU during its Shimokita shakedown cruise, 2006; and then estimated magnitude of minimum principal stress in horizontal plane, Shmin. Moreover, we will propose the test procedures to possibly improve the quality of stress result from the applications of LOT or XLOT. The XLOT of Shimokita cruise was conducted under following conditions; 1180 m water depth, 525 mbsf (meter below seafloor) depth, 1030 kg/m3 fluid density (seawater) and 80 litter/min injection flow-rate. Estimated magnitude of the Shmin is equal to 18.3 MPa based on the assumption that fracture closure pressure balances with the minimum principal stress perpendicular to the fracture plane. For comparison, the vertical stress magnitude at the depth was estimated from density profile of core samples retrieved from the same borehole; and was equal to 20 MPa approximately. These two values can be considered to be not disagreement. Therefore, we can say that the XLOT data is valuable and practical for estimating the magnitude of minimum horizontal stress. From the viewpoint of determining stress magnitude, the XLOT is more essential rather than the LOT because it might be hardly to obtain

    Full Text Available During the Integrated Ocean Drilling Program (IODP Expedition 331 at the Iheya North hydrothermal system in the Mid-Okinawa Trough by the D/V Chikyu, we conducted microbiological contamination tests of the drilling and coring operations. The contamination from the drilling mud fluids was assessed using both perfluorocarbon tracers (PFT and fluorescent microsphere beads. PFT infiltration was detected from the periphery of almost all whole round cores. By contrast, fluorescent microspheres were not detected in hydrothermally active core samples, possibly due to thermal decomposition of the microspheres under high-temperature conditions. Microbial contamination from drilling mud fluids to the core interior subsamples was further characterized by molecular-based evaluation. The microbial 16S rRNA gene phylotype compositions in the drilling mud fluids were mainly composed of sequences of Beta- and Gammaproteobacteria, and Bacteroidetes and not archaeal sequences. The phylotypes that displayed more than 97% similarity to the sequences obtained from the drilling mud fluids were defined as possible contaminants in this study and were detected as minor components of the bacterial phylotype compositions in 13 of 37 core samples. The degree of microbiological contamination was consistent with that determined by the PFT and/or microsphere assessments. This study suggests a constructive approach for evaluation and eliminating microbial contamination during riser-less drilling and coring operations by the D/V Chikyu.

    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)

    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)

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

    Discussions were given on detergents, washing agents and a possibility of a washing technique that impose less loads on the environment. Compacted granular detergent is the mainstream in detergents for clothing. The detergent has a reduced volume, but contains more normal chain alkylbenzen sulfonate (LAS) as a surfactant than the conventional detergents. The current annual consumption of synthetic detergents reaches about one million tons, and soaps about 200,000 tons. Overpopulation and depopulation have become extreme depending on areas, whereas urban areas consume detergents five to ten times the national average. The number of corporations in the soap and detergent industries who take environmental effects of detergents seriously and are trying to develop environment friendly detergents is increasing in recent years. Most of these detergents use natural plants as their main material, using no synthetic surfactants or additives. Bearing the cost for environmental loads and considerations on environment preservation may be adequately incorporated if individuals and corporations make economically reasonable decisions. 7 refs., 32 figs., 18 tabs.

    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.

Running tests of 100,000 times were conducted to confirm effectiveness of durability of the paved road with used papers. Measurement of hardness of the resin using the sol-gel method and coating experiment using organic dye were carried out to study the membrane effect speed and flaw resistance of coating of coloring bottles. Gasification of shredder dust and separation of nonferrous metal and glass were conducted to get the basic data. As to FRP bath tubs, the ratio of glass fiber and plastics was studied and western tiles were trially manufactured.

    Investigations and discussions were given on electric power generation business using as fuel the industrial wastes RDF composed of waste plastics having been manufactured in four blocks in Fukui Prefecture and sewage sludge. The investigations were carried out on estimation of quantity of the industrial wastes available in Fukui Prefecture and quantity of the industrial waste RDF supply, an optimal system for industrial waste RDF power generation, evaluation on economic effects, and environment improving effects. The result of the investigations revealed that the industrial waste RDF can be assured at 80 tons a day, which can make the power generation capacity 5000 kW. The industrial waste RDF manufacturing system adopts a chain type striking, crushing and drying equipment and a fluid bed combustion system. The ash melting system is a multi-phase alternating current system. This system is expected of enhancing the energy saving effect and the CO2 emission reducing effect. Economic effects were discussed on the industrial waste RDF manufacturing business and power generation business both on independent basis and continuous basis. Either case would require industrial waste RDF receiving fee. However, it was confirmed that the business can be realized on the continuous basis. (NEDO)

This reincarnation plan of globe aims to reincarnate the changed global environment hereafter by using time of about 100 years, and proposes to make the comprehensive and long term actions to suppress and reduce exhaust gases resulting the greenhouse effect by the cooperation of all nations in the world. In the former 50 years, feasible countermeasures such as deepenung of scientific knowkedges, promotion of worldwide energy saving, introduction of clean energy, development of revolutional environmental technology, expansion of CO {sub 2} absorbing sources, and technological development of energy for the next generation will be executed continuously. In the latter 50 years, the gas exhausting amount resulting the green house effect will be reduced and suppressed from these results. Owing to these measures, the reduction of gas resulting the greenhouse effect which exceeds the expectation, can clean the globe after 100 years because the cleaning results will be incorporated into the natural circulation and the green globe will be reincarnated. 1 fig., 1 tab

    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.

    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.

    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.

    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.

    A dry battery was developed that does not contain mercury and cadmium having been used in carbon-zinc batteries and alkaline batteries. This paper describes its summary. Mercury in carbon-zinc batteries is used as a corrosion inhibitor for zinc, and cadmium is used to retain mechanical strength of zinc cans. Surfactants and metal oxides were used as a corrosion inhibitor in place of mercury, added into separators. Magnesium was adopted to substitute cadmiun, and the required mechanical strength was obtained. Mercury in alkaline batteries prevents corrosion in zinc particles (which generated hydrogen gas) and gas generation from impurities (iron and others), and plays roles of improving contacts among zinc particles and suppressing electric resistance low. Discussions were given on zinc alloy composition and corrosion inhibitors to replace the mercury having these roles. For zinc alloy, an alloy using lead with less gas generation and excellent discharge characteristics and bismuth as an added element was adopted. 3 refs., 9 figs.

    Magmatic waters are the water contained in magma and the water originated directly from magma, and the latter originated directly from magma is generally called magmatic water. All the magmatic water produced from magma is not necessarily primordial water. Magma emanation is separated from magma, and gradually provided with various characteristics by such phenomena as reaction and mixing with materials in the passage until it erupts to the ground surface as volcanic emanation. In regard to studies on actual magmatic water, descriptions are made on magmatic water, residual magmatic water, as well as magmatic water and the quantity of emanation of Miharayama, a volcano in Izu Oshima. Various kinds of volcanic emanation and magma water are produced from the same lava which is the ground surface magma, even in the same place due to difference in the passage of time since the emission of volcanic emanation and physical and chemical environmental changes (atmospheric phenomena, weather, temperature, and wind velocity). An instance of the presence of various types of magma water is introduced. 37 refs., 5 figs., 7 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 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 recent trends in the environmental problems created from used plastic packaging materials. The 23 wards of the city of Tokyo produce refuses daily of 12,000 tons (1990), with plastics accounting for 15% by volume. Discussions to deal with plastic refuses that are bulky and standing out began as early as in 1971 when the disposal study meeting was inaugurated. As a result, wastes from polyvinyl chloride sheet for agricultural green houses had 40% recovered and recycled out of 100,000 tons generated annually, and styrofoam wastes at 10% of 150,000 tons. The wastes disposal law and the recycling law were established in 1991 aiming at reducing volume of wastes, promoting re-utilization, and assuring appropriate disposal methods and facilities. The Wastes Re-utilization Association was organized to handle styrofoam wastes that are attracting strong attention recently, the association having begun its activities with a good start. It is expected that styrofoam wastes will be molten thermally and regenerated into the same styrofoam products. Styrofoam could be more energy saving and resource saving material than paper cups. 6 refs., 10 figs., 5 tabs.

    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.

    This paper outlines the synthesis and characteristics of substitutive materials of asbestos. Oxide system fibers are used as substitutes and classified into natural and synthetic fibers. As natural substitute, wollastonite fiber is used, while as synthetic substitute, silicate system, alumina system, zirconia system and potassium titanate system fibers are used. Wollastonite distributes in regional metamorphic rock and contact metamorphic zone between limestone and plutonic rock, and is used as heat insulator and adiabator. Silicate system fiber includes glass fiber, quartz fiber and silica fiber, while alumina system fiber includes alumina/silica fiber and alumina fiber. Glass fiber is composed of non-alkaline boro-silicate glass and classified into lint and staple. As fibers similar to glass staple, rock wool and slag wool are used. Only slag wool is produced in Japan because of its lower cost and higher qualitative stability than those of glass wool. Potassium titanate system fiber offers excellent heat resistance, thermal insulation and frictional resistance. 18 refs., 13 figs., 9 tabs.

    In order to develop an airborne asbestos monitoring system, the efficiency of FAM (fibrous aerosol monitor) was evaluated in which the scattered light due to vibration of fibrous particles is detected by applying He-Ne laser to the particles after vibration was induced in them by high voltage quadrupole electrodes. As compared with the data concurrently obtained by phase contrast microscope (PCM) and transmission electron microscope (TEM), no correlation of an asbestos concentration was observed between FAM and PCM in low concentration environment, however, FAM offered comparatively reliable results in high concentration environment. As an asbestos concentration was measured with time by FAM around a duct outlet during removal of sprayed-on asbestos, FAM responded instantaneously to emergent emission of a large amount of asbestos in the event of dust collector failure for example. FAM was thus useful for monitoring asbestos leakage. 8 refs., 6 figs., 3 tabs.

    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)

    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.

    This paper describes underground environmental issues to which geophysical exploration can be applied. Especially, ground pollution, waste treatment and unexploded ordnance (mine) detection are discussed by considering worldwide technology trends through examples in Japan and the USA. Since environmental surveys are generally conducted for regional and rather shallow ground, rapidity, economy and high resolution are required for geophysical exploration. In response to these demands, a mapping system using capacitor electrodes and a complex resistivity method for detecting organic compounds are promising for the electrical prospecting. A shallow electromagnetic method is being standardized for the electromagnetic prospecting. A cesium magnetic gradient meter is also being standardized for the magnetic prospecting. An underground radar, seismic prospecting, and gravitational prospecting are also applied to some grounds. Prospecting of pollution sources, high- and low-concentration ground pollution, monitoring of pollutant removal, soundness survey of water barrier in management-type waste treatment place, and detection of unexploded ordnance are illustrated for the examples. 15 refs., 10 figs., 4 tabs.

    Tests and studies were started for the verification of the coated tubing developed using the element technology introduced in the special study `Production Technology in High-Temperature Corrosive Environments`, for the development of oil exploring equipment serviceable in corrosive environments, and for the development of programs for selecting materials for use in corrosive environments. In connection with verification tests, investigations were conducted into the operating fields of domestic oil exploring corporations and into technical literature relating to the deterioration of basic materials in their resistance to SSC, and basic data were accumulated. In the efforts to develop equipment, it was decided that drilling stabilizer blades be developed by plasma sintering, that information be collected concerning technologies relating to functionally gradient materials, and that technologies be developed for YAG-laser cladding of flange seal surfaces and elbow inner surfaces. As for the development of material selecting programs, various tests were conducted into the 13Cr steel and super 13Cr steel for their SSC, total corrosion, and local corrosion, their performance was evaluated, and the limit of their serviceability was determined by mathematical treatment. 7 figs., 3 tabs.

    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.

    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 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.

    With relation to the coal of the Philippines, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/development, the trend of coal import and domestic distribution, the coal utilization trend, and environmental problems, and analyzed the situation of coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to draw up a master plan for the introduction of the environmentally-friendly coal utilization system. As to the use of environmentally-friendly coal technology which should be adopted to the coal mining industry and commercial/residential sector, cited are the introduction of coal preparation technology and power transmission technology, and the development/spread of briquette as a firewood substituting fuel. In the electric power sector, the problem is the treatment of ash after combustion and the effective use. Relating to the treatment of flue gas, there is no installation at all of desulfurization facilities and denitrification facilities. In the cement industry sector, they wish to return fuel from heavy oil to coal. For it, it is necessary to study dust preventive measures. In the other sectors, coal hasn`t been used very much. An increase in coal demand is not expected also in the future, and big problems concerning coal haven`t occurred. 42 figs., 64 tabs.

    It is necessary to establish scenarios for reducing CO2 emissions and for developing CO2 emission control technologies to obtain a global consensus, using appropriate analytical models. For modification of the DNE-21 (Dynamic New Earth 21) model, it has a category designated as innovative technologies not involving CO2 emission and an optional consideration for the absorption of atmospheric CO2 by biomass. A global carbon circulation model, including vegetation in its scope, is also incorporated. Major results of the simulation are shown. When 20% reduction in CO2 emissions is required for only OECD countries after the year 2020, it has been demonstrated that CO2 concentration in the atmosphere will reach as high as about 900 ppm in 2100 due to CO2 emission by developing countries, and will not be a tolerable level. Under the condition that CO2 concentration in the atmosphere is controlled at 450 ppm in 2100, the amount of renewable source of energy from photovoltaic power generation and biomass will increase and technologies of CO2 recovery and storage will decrease. Research and development of the production of methanol from recovered CO2 will be adopted as innovative technology for CO2 measures. 69 refs., 112 figs., 79 tabs.

    It was recently confirmed that a large quantity of hydrothermal solution has been gushing out at back-arc basins and ocean ridges. Therefore, effects of the hydrothermal solution on the seawater composition have been studied in many ways. In this report, balance of arsenic in seawater is investigated since arsenic has a higher concentration in hydrothermal solution than in seawater. Trial calculations are conducted based on the arsenic concentration in hydrothermal solution and the seawater/hydrothermal-solution circulation amount. As a result, it is assumed that the hydrothermal input flux from island-arc/back-arc basins into seawater is much higher than that from ocean ridges. The total hydrothermal input flux is (0.28-5.36) [times] 10[sup 11]g/year, which is equivalent to or higher than that of river flux. The total input flux of arsenic including input from volcanic gas is in the same order as the output flux of arsenic due to the pyrite formation within submarine sediment. It is estimated that the subduction flux into the depth of the crust is lower than the hydrothermal flux from island-arc/back-arc basins. Therefore, it is inferred that most of the arsenic subducted into the crust would be circulated in the ocean. 23 refs., 2 tabs.

    Elaboration of the action plan for the New Earth 21 plan proposed by Japan in Houston Summit was researched. In fiscal 1995 three types of energy supply/demand scenarios, sensitivity analysis under various conditions, and cases presupposing CO2 emission regulations or not were evaluated by analysis toward 2050 using the New Earth 21 Model (NE 21 Model). Energy-saving is important, and CO2 recovery/treatment technology is introduced according to CO2 emission regulations, while attention is focussed on biomass energy. The issue of solar and wind power generation is cost reduction. In a presupposed horizontally integrated energy system, methanol represents an important intermediate energy. As a whole, CO2 reduction can be achieved by various combinations of energy-saving, introduction of regenerative energy, and CO2 recovery/treatment technology. Case studies of the action plan were conducted by unifying the evaluation criterion on coal IGCC, photovoltaic generation and biomass. The NE 21 Model was useful for elaboration of the reduction scenarios of CO2 emission. 26 refs., 84 figs., 28 tabs.

    When fluid production from a geothermal reservoir is started, fluid inflow from the reservoir surroundings and reduction zones starts following a pressure decrease in the production zone. For grasping the conditions of a reservoir after the start of production, a geophysical monitoring technique attracts attention. It is an indirect technique compared with drilling observation, but it will be more widely used in the future in grasping macroscopic variation in relation with thermal energy production. This paper describes a monitoring technique on the basis of gravity and natural electric potential as well as an analytical technique on the basis of a reservoir mathematical model. NEDO is presently engaging in by the schedule of 1997-2004. As the results of this project, it is expected that analytical techniques to apply various monitoring techniques and obtained data to history matching are developed as practical techniques. (NEDO)

    In Candidate C area for the geothermal development survey, the natural environment was surveyed and `the secondary landscape assessment` was summed up in which places proposed for drilling of large-size wells and for construction of power generation facilities are extracted and a simulation of the landscape is conducted. The area for survey is the Shiramizu-gawa region in the south of Lake Akan, Akan-cho, Akan-gun, Hokkaido. The field survey was carried out about three items of landscape, plants and animals during the June-November period, 1995. As to the flora, diverse florae including vegetation unique to alpine areas, wetlands, and fumarole surrounding areas were found in the region, which is covered with summer-green broad-leaved forests or mixed forests of coniferous and broad-leaved trees. As to the fauna, faunae inhabitant of the highly natural forests were found including black woodpeckers and mountain hawk eagles. As a result of studying the places proposed for geothermal development from the above-mentioned survey, two places were picked up in the west of the survey area, where geothermal development is comparatively less influential in the natural environment and landscape and there is a high locational adaptability. 19 refs., 56 figs., 49 tabs.

    Learning from a history of the earth of ancient times, the paper studies effects of refreshing environment and soil or making them natural and harmless mostly using primitive bacteria, and develops element technology which is industrially accelerating. The spread type accelerator working only by solar energy was installed and operated for experiment. As indices of refreshment effects, a study was comparatively made between a sugar degree of sweet potato and a yield shown in the number of potatotimesunit weight. An EM propagation garbage layer is formed, and the two sections were installed of a site of the actual installation of the spread type accelerator and a site naturally left alone. Other effects of weather, temperature and humidity which are external factors and general fertilization are offset as common modes, and a consideration was so made that only refreshment effects of primitive bacteria can be relatively compared. Acceleration effects in using accelerator for growing sweet potato could be quantitatively confirmed. As to sugar degree, because the last study was made in the beginning of summer, the underground temperature was high enough. Even only EM effects were fully effective. This time, the weather was much colder, and it was found to be a must to use accelerator. 2 figs.

    A sharp rise in industrial productivity in Asia countries indicates a rising level of R and D technology. Since Japan has not clearly grasped the R and D ability in these countries, it has not given appropriate personnel/material R and D support to them. Therefore, for the purpose of exactly grasping the R and D ability of Asian countries (Korea, Taiwan, the Philippines, Indonesia and India) and studying an effective and appropriate method for R and D cooperation, a survey was conducted of R and D potentials in Asia and R and D support policies of the countries. As a result of the survey, the following are taken up as items to be considered: promotion of exchanges between Tsukuba, etc. in Japan and research/university towns and science parks being constructed in lots of countries, participation of private companies in high-tech joint work in cooperation with Japan, sending information from Japan using internet, etc. and exact grasp of needs at partner side, cooperation given to new comers without asking for research results (use of OB researchers, etc.) 25 refs., 39 figs., 59 tabs.

    This report studies changes in international competitiveness of individual industry in Japan and the U.S. between 1960 and 1985 by using time series data in Japan and the U.S. on the basis of the measurement of productivity in both countries and the measuring rule for the absolute comparison of their level. The conclusion is summarized as follows: 1. Technological advance rate in both countries dropped rapidly after the oil crisis, but showed an average tendency to recover in 1980s; that is, it does not necessarily indicate a time series tendency to decline. 2. A technological gap between Japan and the U.S. expanded in 1970s, reached the peak in 1980, and reduced again during 1980s, however, dispersion among industries has tended to expand. 3. The future trend of a technological gap between Japan and the U.S. shows bipolarity. In Japan, technologies with big trade scale in the field of chemicals, electric machines, and precision machines attain superiority. 4. The price competitiveness reflects a gap of technological efficiency and factor prices respectively. Nevertheless, there are some Japanese industries having an advantage over the U.S. since they offset a gap of factor prices against a technological gap. 9 figs., 4 tabs.

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

    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. The second experimental system using LOD (lactate oxidase) was thus constructed to examine the heat-stability landscape. In addition, the system of in vitro molecular evolution of proteinase inhibitor (Cystatin B) was constructed. 3 refs., 3 figs., 2 tabs.

    This paper is a translated, edited version of a lecture given at Business Consultative Meeting of Eight-Nation Energy Ministers` Conference convened in Moscow in March, 1998. This is a Russian investor`s opinion about the conditioning for the attraction of private sector investors to Russia`s energy industry. The economic development of Russia will depend on the magnitude and efficiency of the investment in oil and gas projects. So as to overcome the current inactivity of oil industry, Russia will need an investment of 6 to 20-billion dollars a year. Furthermore, according to the micro-economy level calculation, the required investment will be 130 to 140-billion dollars a year. Under the circumstances, what is necessary is to work out conditions to be most favored by the investors. For the attraction of an increased number of investors, two methods are under consideration. One involves the improvement of the currently valid underground resources utilization system (licensing system), and the other involves the formulation of a competitive underground resources utilization system based on the mechanism of agreement on products distribution. 4 figs., 1 tab.

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

    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.

    The aim of our project is to develop high-performance processor architectures for both general purpose and application-specific purpose. We also plan to develop basic softwares, such as compliers, and various design aid tools for those architectures. We are particularly interested in performance evaluation at architecture design phase, design optimization, automatic generation of compliers from processor designs, and architecture design methodologies combined with circuit layout. We have investigated both microprocessor architectures and design methodologies / environments for the processors. Our goal is to establish design technologies for high-performance, low-power, low-cost and highly-reliable systems in system-on-silicon era. We have proposed PPRAM architecture for high-performance system using DRAM and logic mixture technology, Softcore processor architecture for special purpose processors in embedded systems, and Power-Pro architecture for low power systems. We also developed design methodologies and design environments for the above architectures as well as a new method for design verification of microprocessors. (NEDO)

    The analysis of the organic pollutant in the environment is carried out as the following procedure; the organic substance is extracted by using the organic solvent from a collected sample, an instrument analysis such as gas chromatography (GC) or high performance liquid chromatography (HPLC) are done after the clean up the sample by column chromatography. The analysis using supercritical fluid instead of the organic solvent in each stage is supercritical fluid extraction (SFE) or supercritical fluid chromatography (SFC). The supercritical fluid has a density and viscosity coefficient between gas and liquid, and the control of the dissolving power is possible by the change of temperature and pressure. Therefore, it has the advantage as follows: The material mobile speed is high and separation and extraction are rapid; It is easy to adjust the dissolving power and possible to carry out selective separation and extraction; The removal of solvent can be easily carried out since supercritical CO{sub 2} used is a gas in the normal pressure. In this paper, the analytical instrument in which the extraction is carried out in organic solvent and clean up was done in SFC was introduced. (NEDO)

    As a series of the studies on the mechanical properties of spider threads, the effects of ultra- violet rays (UV) and water was investigated using drag lines of Nephila clavata (Jorougumo) and capture threads of Argiope amoena (Koganegumo). It was shown for the effect of water that (1) the drag line was contracted as soon as immersed in water (super contraction), while the capture thread was not so contracted and the viscid droplets attached to it were dissolved in water, and (2) the super contracted drag fine behaved like a capture thread with a j shaped load-draw ratio curve. For the effect of UV, it was found that (1) the degradation due to UV irradiation with short wave length was accelerated more than that with long one and (2) the degree of degradation for each wave length was governed by the integrated irradiation energy of UV. 9 refs., 8 figs.

    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.

    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.

    For active environment technology export to OECD countries, needs for environmental measures in developing countries were surveyed. Both collection of environment technology needs in developing countries and preparation of technology seeds information of Japanese enterprises, and promotion of environmental projects by adding an information dispatch function are important. Active preparation and exchange of experiences and know-how of concerned enterprises, local governments and national organizations are also necessary. For development and possible export of small- and medium-sized ventures with excellent technologies and know-how, a suitable consulting system is essential for risks. For smooth promotion of warming prevention by international cooperation, active development of monitoring technology is also important. To support developing countries, OJT of persons in charge in technology transfer sites, and preparation of information infrastructure are necessary. Japan with much know-how on environmental preservation should positively participate in international standardization activities such as ISO. 10 refs., 14 figs., 56 tabs.

    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.

    CO2 emission was quantified through the life cycle of a solar water heater to assess its environment impact. Although LCA (life cycle assessment) originally sums up I/O of all materials and energy through the whole life cycle of a product to examine environment impact, this assessment was carried out for only CO2. Calculation of CO2 emission assumed a natural circulating solar water heater of 200 l in effective hot water capacity, 2.78m{sup 2} in effective collecting area, and 0.5 in average annual collecting efficiency of total solar radiation, and an auxiliary city gas heat source for compensating insufficient heat quantity. The total CO2 emission in the life cycle of a solar water heater was obtained from an industrial association table assuming the life cycles of 10 and 20 years. CO2 emission was estimated to be 5407.1kg-CO2 and 10665.2kg-CO2 for 10 and 20 years, respectively. CO2 emission due to city gas was largest in the total CO2 emission in the life cycle. As a result, for reduction of CO2 emission due to a solar water heater, improvement of equipment efficiency was most important. 6 refs., 5 figs., 3 tabs.

    Primordial microbes that can function as photosynthetic catalysts are utilized in establishing a safe method for treating liquid or solid pollutant oxide wastes and household wastes and in activating vegetables` assimilation of gaseous wastes. A method for industrially accelerating their environment refreshing function and another method (the subject method) for measuring the effect are discussed. The technique of putting such methods to practical use is introduced, and the effectiveness of the said measuring is confirmed using empirically accepted rules. This method is based on the mycobiont/companion group method (EM method) that is advocated by Professor Higa of University of the Ryukyus. The group members form colonies with their symbiotic yeasts, lactic acid bacteria, actinomyces, leguminous bacteria, and nitrifying bacteria. Using this method, energy is industrially injected for acceleration and, simultaneously, the resultant effect is measured. The result of the measurement is next fed back so that the acceleration will be reflected. In this way, the effect of the primordial microbes that function as photosynthetic catalysts is confirmed and, secondarily, the basis is prepared on which element technologies will be developed to contribute to the enhancement of the multiplication of vegetables. 11 refs., 7 figs.

    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.

    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.

    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)

    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.

    This paper reports a summary of the large enviromntal application facility to perform strength tests on composite materials under varying temperature environments. The facility features the capability of providing uniform temperature and humidity distributions in an environmental space of 9[times] 5[times]3 m, and covering a wide temperature range from[minus]70[degree]C to 200[degree]C. Since the environmental room temperature of 200[degree] C is not sufficiently high to meet high-temperature structural testing requirement for HOPE, an auxiliary ceramic heater was brought into the environmental room to heat only the required area up to 350[degree] C. A hydraulic actuator including the already introduced high-load loading equipment was installed in a space under the environmental room rack, and loads are induced to an extension rod attached to the load terminal in the actuator. Tests scheduled include a fatigue test on CF/thermoplastic composite filament winding beams for high-altitude unmanned spacecraft under a use temperature of [minus]60[degree]C, which is under preparation at normal temperatures, and a high-temperature strength test on polyimide CFPP structure for HOPE to follow the former test. 5 figs., 1 tab.

    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 report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

    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.

    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.

    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.

    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.

    The Sakai Factory of KURIMOTO LTD. employed a continuous porous plug desulfurization method in 1992. In this desulfurization method, the molten iron from a cupola is desulfurized with a desulfurizing agent in which calcium carbide and lime are mixed. This paper reports the details of the development of a simultaneous desulfurization/graphite spheroidization method using Mg, which aims at disusing the operation in a high-temperature environment and reducing the quantity of slag which is an industrial waste. The main results obtained are as follows. The quantity of desulfurized slag in a porous plug ladle could be reduced to zero. A total quantity of slag produced was reduced by about 70%, which was better than the target reduction. Owing to the employment of this simultaneous desulfurization/graphite spheroidization method using Mg, the operations of mixing the desulfurizing agent and removing desulfurized slag in a high-temperature environment were omitted. The S-value after the simultaneous desulfurization/graphite spheroidization became lower than 0.010%.

    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.

    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)

    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)

    In order to evaluate presence or absence and extent, if present, of the effects of drilling a geothermal well, changes in flowing-out rate of hot spring and others were surveyed at the hot spring resorts in the Kuwanosawa area and its peripheries, extending around 18 km{sup 2} area in the mountains approximately 20 km to the south of City of Yuzawa, Akita Pref. Three sites were selected; the hot spring resort of Takamatu, a hot spring resort at the foot of mountain, and another hot spring resort near the dry riverbed of the Takamatu River, where hot spring spontaneously flows out in all of these sites, from the 1,500 m deep boring at the first site, and in the area where steam is gushing out in the second site. The surveyed items were rate of flowing-out, temperature, electroconductivity, pH and various ion concentrations of the hot spring, and precipitation. The survey was conducted 19 times from August 9, 1999 to July 12, 2000. For the effects of drilling the geothermal test well and drawing-up the hot water, some surveyed items changed significantly in these 3 resorts. These changes, however, largely result from seasonal reasons as well as conditions within each hot spring well, and not from the drilling of the geothermal test well N11-KN-1 and drawing-up of the hot water.

    This paper describes the main features of flood plains and fish production related to agriculture in the vast inland water areas of Bangladesh. The inland fisheries have been an important source of animal protein and provided employment opportunities for rural Bangladeshies. Generally the fishermen's economic conditions are below the poverty line in this country. Fishi production in the inland water areas are not met to the basic needs of the people on a sustainable basis. While inland fishery is important for business as well as for people's livelihood, it is not usually managed appropriately for resource conservation and environment. Fishery policies and planning have to be undertaken for comprehensive long-term perspective in order that agricultural and other sectors would not contaminate the environment. (author)

    To suppress the emission of environmental pollutants from coal utilization in Indonesia and to contribute to stable security of Japan`s energy, demonstration of clean coal technology and consolidation of diffusion base to be introduced into Indonesia have been promoted. Briquette production plant installed in the Tanjun Enim Coal Mine was examined and guided. Two kinds of high-volatile subbituminous coals are used as raw materials. Semi-cokes with volatile matter of 20% are prepared through fluidized carbonization at 480 degC. Hydrated lime or clay and binder are added to the semi-cokes, to manufacture ball briquettes by molding at room temperature. These are forcedly dried in the continuous drying furnace. In the design, 5 ton ball briquettes can be produced for an hour. Operation time is between 8 and 15 hours in a single shift. Products completely without smoke and smell can be obtained. Combustion performance of the products is remarkably superior to that of conventional products. The operation techniques of carbonization and molding processes were actively guided. To produce briquettes with further high quality, it was suggested that blending ratios and coal properties should be investigated. Inspection method for each apparatus was also guided. There was no abrasion. 13 figs., 2 tabs.

    This research was made for investigating the impact of geothermal development on hot spring, ground water level and spring water by drilling 3 investigation wells N9-AY-3, N9- AY-4 and N9-AY-5 in Akinomiya district. Some research items for hot spring showed slight fluctuation until 1997, however, those showed no fluctuation due to drilling of the 3 investigation wells in fiscal 1998. These results suggest that drilling of the investigation wells has no effect on the spring and quality of hot water in Akinomiya district. Drilling of N9-AY-4 well is carrying out continuously after Sept. 1998. Fluctuation of ground water levels was dependent on precipitations, however, drilling of the 3 investigation wells has no effect on the ground water level. These results suggest that drilling of the investigation wells has no effect on the spring of hot water in Akinomiya district. Every research item for spring water showed relatively slight fluctuation stably. These results suggest that drilling of the investigation wells has no effect on spring water in Akinomiya district.

    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.

    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.

    An investigation was conducted with the aim of elucidating the foundations for effective utilization of environmental pollutants or unused resources which are likely to be causal substances of environmental pollutants, as resources, using biotechnology. Composting of agricultural waste, production of microbial mycelium proteins and microbial fermentation materials were suggested as main examples of effective utilization of unused resources by microorganisms. Selection of active microorganisms in the livestock waste, clarification of the mechanism of action and the establishment of treatment conditions are essential to new developments in this field. In the field of marine products industry, it was pointed out that the recycling of waste using microorganisms and enzyme treatment is the most promising approach to the effective utilization of resources. In the field of food industry, applications as the culture media for mushrooms, for enzyme production and for the production of physiologically active materials as well as fuel were clarified. Was also pointed out the significance of studies on the microorganisms and enzymes in resources containing cellulose, hemicellulose and lignin, and the waste from these resources, lignocellulose. Were also proposed the composting of household waste, methane fermentation, and fermentative production of organic acid and hydrogen from waste. Possibility and significance of fermentative production of organic acid from sewage sludge were suggested. 314 refs., 46 figs., 33 tabs.

    The purpose of this study was to examine the progress of development in the vicinity of Kibana district which was formerly surrounded by forests on the mountain and agricultural fields, but is currently a village in the rural-urban fringe transfigured by a large-scale educational city project after the removal of Miyazaki University. It was conducted by making a comparison with the relation between the development and the rise in land surface temperature. Changes in the environment were investigated using remote sensing technologies through preparation of a land classification map and a land surface temperature map by a utilization of a personal computer together with the obtained Landsat Thematic Mapper Data for the years of 1989 and 1990. As a result, it was found out that though the result of temperature comparison between 1989 and 1990 was 1.4[degree]C and 2.8[degree]C higher in 1990 at the lowest temperature and the average daytime temperature respectively, more difference was observed at land surface temperature in the land surface temperature map; and also, although evolution of mountainous areas to populated areas, overpopulation in residential quarters and expansion of populated areas, etc. were observed in the land classification map, agricultural and grass field areas augmented their image element number due to the unusual warm winter in 1990 and the inevitable rapid growth of grasses and flowers. 4 refs., 3 figs., 7 tabs.

    With an objective to give some suggestion to the water resources policies for the future Japan, a comparative study was made on the water resources development policies in Japan and the water resources policies in the state of California, U.S.A. The study on Japan has been proceeded empirically based on specific data with regard to the development of electric power policies from the prewar to postwar times when the governmental electric power control was changed to incorporation of the nine electric power companies. The change may be identified from viewpoints of both profit and ideology. Noticing the `public corporations` established one after another for social capitals before and after the establishment of the Liberal Democratic Party, their relation with the water resources development policies was pursued in terms of actual proof and political science. The identity of the public corporations established in and after 1955 stands on the premise of free economy, rather than the controlled economy. This paper positions the water resources development policies in a broader context as the national land plan, and considers the problems that are expanding from flood damages, dam construction, industrial complex construction to environmental problems around the water. Comparative discussions on the Tone river system and the Colorado river system were left as the future assignment.

    In order to investigate the causal relation of change in vegetation status with the power station after starting the operation, pine trees in the surrounding area were studied in tree ring characteristics. The sampling was made at six stands ranged from the Tohhoku district to the Chugoku district. Pinus densiflora and P. Thunbergii were 0.1 to 16.2mm and 0.05 to 9.05mm, respectively, in tree ring width. They were, in frequency distribution, both a logarithmic normal distribution with 1.05 to 1.50mm in mode. Their frequency distribution being a logarithmic normal distribution, along with advance in years thereafter it transfers to a normal distribution, then to a logarithmic normal distribution, then to an L-shaped distribution. Pinus densiflora and P. Thunbergii were 6.5+-3.5mm and 6.5+-2.5mm, respectively, in maximum tree ring width, of which the appearance ratio was high in trees, 4 to 12 years old. While the minimum tree ring width appears, when the tree is very young in age and in specific calendar years during its second half of life. As for the time series of tree ring width, it, small when one year old, continues to enlarge along with advance in years until about ten years old, attains the maximum and, after then, diminishes along with advance in years. 6 refs., 7 figs., 3 tabs.

    In Asian countries, the economic growth rate is extremely higher as compared with the world average, and accordingly a large growth in energy supply/demand and electric power supply/demand is paid attention to. Besides, at users` side, a fear is the worsening of the environmental problem which is brought about by a rapid increase in energy consumption. At suppliers` side, introduction/expansion of a large amount of foreign funds for rapid promotion of power source development become necessary so that supplying facilities catch up with the growth in demand. Moreover, dependence of the supply upon outside the area is becoming higher, and problems in safety guarantee are also becoming prominent. As for energy/power source mix in East Asian countries, the stable supply is basically considered as most important, and economical efficiency is also important including competition conditions among energies and potential raising of investment in supplying facilities. It is no exaggeration to say that the increase in the rate of coal which occupies most of the primary energy supply/power source in East Asian countries depends upon the progress of environmental harmony technology such as clean coal technology. 39 figs., 132 tabs.

    A survey was made to study possibilities of Japan`s cooperation in tackling energy/environment problems in Asian countries. In 1995 the GNP growth rate was 2.6% in the world, while it was 7.9% in Asia showing a rapid growth. With the accelerating industrialization and urbanization, energy demand is now over three times as much as that in the 1980s. This means increases in waste and environmental pollution. Especially, the use of firewood in non-electrified areas is a serious problem the same as the slash-and-burn farming and deforestation. Also relating to the production of electric power, it is inevitable to choose hydroelectric power and renewable energy in addition to fossil fuels. Therefore, the necessity is heightening of various technologies for it and environmental protection technologies such as coal cleaning. Local areas, where the population density is extremely low and the electrification cost is high, became victims of elecrification. There the power system should be shifted from the central supply system to the local distributed one. For it, it is necessary to recognize an importance of the distributed type renewable energy which is friendly to the environment. The paper outlined the state of each country and energy by policy and environment. 10 figs., 83 tabs.

    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.

    At the third Conference of the Parties to the United Nations Framework Convention for Climate Change (COP3) held in December 1997, the industrialized nations have agreed on development and proliferation of innovative technologies under international cooperation and transfer of environmental technologies to developing countries by expanding and strengthening CTI being the framework to be progressed spontaneously. Under the international strategic research project for global environment, NEDO has been promoting positively the research and development, whose support is urged to be expanded further in the future upon receiving the present agreement. Therefore, NEDO has performed the present survey in order to propose frameworks and measures for strengthening and expanding CTI. From among the policies and measures to be taken by the related countries based on the COP3 protocol, fiscal 1997 has performed review and new establishment of plans involved with execution of the items related to technology development, and surveys on action movements such as review and expansion of the measures, as the first stage. Fiscal 1998 has executed surveys focusing on the network for technology proliferation and transfer to developing countries as the second stage. (NEDO)

    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.

    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.

    Dogo Spring is a non-volcanic hot spring (not a spring that gushes up in association with live volcanic activities) and located about 10 kilometers away from the coast line. Therefore, the spring water quality is not affected by these geological environments, allowing the interactions with the mother rock to be identified relatively easily. In order to investigate the relationship between chemical constituents in the hot spring and the mother rock, a leaching test was carried out on boring-cores and representative rocks existing in Ehime Prefecture. Considerations were given on the factors in the mother rock affecting the hot spring constituents, the high pH value in Dogo Spring, and the origin of the constituents. The result indicated that pH value in the leaching solution from the boring-cores taken from Dogo Spring is higher than that in the leaching solution from representative rocks in Ehime Prefecture; it suggested that the high pH value in Dogo Spring is correlated to the gushing mother rock (Ryoke granite); it also suggested that the Dogo Spring water has about the same concentration as in the dissolved constituents in the leaching solution from the Dogo Spring boring-cores, and the dissolved constituents in the Dogo Spring water is closely related with the composing mother rock (Ryoke granite). 12 refs., 9 figs., 6 tabs.

    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

Reduction of environment burden, improvement of the productivity and reliability of products, and creation of new industries by novel creative R and D are necessary simultaneously. For reconsideration of the previous measurement and machining technologies in a manufacturing industry, use of photon (laser) beams is promising. As photonics engineering, photonics measurement and machining, and elemental and peripheral technologies for generation and control of photon were surveyed. Photonics application technologies for medical care and diagnosis, communication and transmission, entertainment, and chemical fields were also surveyed. In fiscal 1997 as the first year of this project, based on the results obtained in leading researches conducted until fiscal 1996, some technological issues were clarified through the survey on the latest trend of photonics engineering in measurement, machining and generation fields, and its feasibility in the other fields. 265 refs., 91 figs., 10 tabs.

    For use of advanced functions of bioconsortia (complex microorganisms composed of more than 2 microorganisms with certain specific function), this project analyzes specific functions of specific organisms and the interaction between the specific functions, and develops isolation and incubation technologies of component organisms. In fiscal 1998, to promote this project, the meetings were held frequently in National Institute of Bioscience and human Technology. Study was made on production of useful substances and useful degradation functions in association with bioconsortia. The result showed that microorganisms coexisting with nematode produced physiologically active substances exhibiting antimicrobial activities to tubercle bacillus, MRSA and others, microorganisms coexisting in eggs of some insects produced substances having antiviral activities and activities against pathogenic bacteria in a plant, and microorganisms growing in some plants or mycorrhiza organisms produced insecticidal substances or growing-promoting substance. The basic understanding was obtained on cooperative actions of bioconsortia to bioremediation and degradation of organic substances. (NEDO)

    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.

    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)

    This paper describes nurturing of human resources in chemical technologies, as part of the surveys in fiscal 1999 on foundations for establishing industrial technology strategies. In association with the progress in scientific technologies, convenience of living has been enhanced exceptionally. On the other hand, however, problems lie in a heap, such as in global environment, energy, resources and population. Safety of chemical substances is questioned. Industrial world is greeted with the times of bubble collapse, information orientation, internationalization, and great competition. Chemical industries are aiming at differentiation and power strengthening, but demanded of conversion into making more independent developments. A large number of problems difficult of solving must be overcome by progress of scientific technologies. The core of the progress is in innovation and creation of new chemical technologies. Since what shoulders the requirements is people, nurturing chemical engineers is the urgent and important issue. Chemical engineers are demanded of having knowledge and experience in environment and safety, and ethics to accomplish social responsibilities, not to speak of their specialty technologies. Human resource nurturing must be carried out effectively under collaboration and cooperation of universities and corporations, rather than they do it independently. This paper describes problems and solution ideas, such as institutions and programs, to achieve the goal. (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.

    Technology development was conducted for production of useful substances using the bioconsortia system. In FY 1998, the development of element technology was studied. As to the utilization technology of gut symbiotic microorganisms such as termite and longhorn beetle, clone types of gut microorganism complex system were analyzed to find out the diversification. In the decay of wood, co-culture of two species of mold fungus was increased in efficiency than single culture. More than 90% was classified/identified of the mold fungi accumulated (in wood piece)/separated for the utilization of plant symbiotic microorganisms. For the production of petroleum substituting useful resource, conditions were established of callus induction from immature embryos of tropical oil crops, especially oil palm, and of regeneration of a lot of small plants from the callus. To establish the Agrobacterium-mediated transformation system of oil palm, the binary vector harboring the reporter gene and selectable marker gene was constructed. Using the vector, oil palm tissues are inoculated and infected with agrobacteria. To heighten the function of palm oil, 10 particular clones were selected from the complementary DNA library obtained from oil palm fruit tissues. The genetic study of germs was also made. (NEDO)

    The utilization in Japan and abroad is discussed of desalination methods using evaporation, reverse osmosis (RO) membranes, and electrodialysis membranes, out of various desalination techniques for seawater and others containing more salt. A new seawater desalination plant built in Okinawa, Japan, is outlined, and the future trend of Japan`s efforts for desalination is predicted. The said plant in Okinawa is the largest ever built in this country, and occupies 4th or 5th place in terms of capacity among similar facilities across the world. It was completed in April, 1997, and produces pure water at a rate of 40,000m{sup 3}/day. This plant, operating on RO, comprises eight RO membrane units each capable of 5131{sup 3}/day. The membranes are of the spiral type, consisting of Toray`s crosslinked aramid-base composite membranes and Nitto Denko`s membranes composed totally of crosslinked aromatic polyamide. The greatest of the pending tasks is to reduce the desalination cost. As for the operating cost of the desalination facility at the current stage, it costs 120-130 yen/m{sup 3} on the 40,000m{sup 3}/day scale, and the power cost occupies approximately 60% of the total operating cost. It is concluded that the consumption of electric power and chemicals per pure water produced have to be reduced. 8 refs., 5 figs., 5 tabs.

    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.

    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.

    A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (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.

    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)

    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)

    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.

    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.

    This paper reports the study results on development of composite materials for solar cells under microgravity environment in fiscal 1994. (1) On a thin film capillary method, 26 experiments of GaSb thin film crystal growth were conducted using the especially prepared high-accuracy electric furnace under microgravity. The wettability of thin film crystals was improved by refining equipment. Rhombus crystal planes and large crystal grains were observed in GaSb thin film crystals prepared under microgravity. (2) On a liquid phase method, the effect of the gravity on crystal structure and grain morphology was studied for synthesis of CdS fine grains. (3) On technological development of composite materials, the solidification experiment of Cu-In-Se melt was conducted under short time microgravity of 10{sup -4}g for 10 sec. As a result, more uniform texture and more high crystallinity were obtained under microgravity, and In in melt was concentrated by surface tension effect. It was suggested that high-quality CIS thin films will be obtained by Se doping into Cu-In composite films under microgravity environment.

    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.

    For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

    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.

One of the scientific purposes of the vessel is to investigate into unexplored biosphere (i.e., undescribed extremophiles) on the Earth. Therefore, "the onboard laboratory" provides us systematic microbiological protocols with a physical containment situation. In parallel, the onboard equipments provide sufficient space for fifty scientists and technical support staff. The helicopter deck also supports various logistics through transporting by a large scale helicopter (See, http://www.jamstec.go.jp/chikyu/eng/). Since the establishment of Panel on Planetary Protection (PPP) in Committee on Space Research (COSPAR), we have an international consensus about the development and promulgation of planetary protection knowledge, policy, and plans to prevent the harmful effects of biological contamination on the Earth (e.g., Rummel, 2002). However, the matter to select a candidate location of initial quarantine at BSL4 level is often problematic. To answer the key issue, we suggest that international waters can be a meaningful option with several advantages to conduct initial onboard-biological quarantine investigation. Hence, the research vessel Chikyu is promising for further PPP requirements (e.g., Enceladus sample return project: Tsou et al., 2012).

    Development has been advanced on technologies to manufacture methanol efficiently by combining a technology to convert selectively fibrous material based biomass into sugar under high concentration sulfuric acid condition with the immobilized enzyme flash fermentation process, both being developed in the United States. Activities have been taken in the following three fields: 1) establishment of an optimal biomass treatment condition by using concentrated sulfuric acid, 2) chromatographic separation of sugar and sulfuric acid, and 3) discussions on conditions to apply the immobilized enzyme flash fermentation process. In Item 1), discussions were given, using rice straw and waste woods as the object, on effects of biomass particle size, sulfuric acid to biomass feeding ratio, sulfuric acid concentration, reaction temperature and time on the cellulose to hemicellulose reaction ratio and the sugar conversion factor, whereas it was revealed that the governing factors are the biomass/sulfuric acid contact area and the reaction temperature. In Item 2), a chromatographic device filled with anion ion exchange resin was used to set the sugar recovery rate of 100% and the sulfuric acid recovery rate of 93%. (NEDO)

    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 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.

    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 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.

    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).

    D/V Chikyu implemented by CDEX/JAMSTEC joined IODP from 2007. Various LWD (Logging While Drilling) and wireline logging have been carried out in many expeditions and for various purposes. Significant features of logging in Chikyu expeditions are many use of LWD than wireline logging, and riser dirlling. riser selected specific tools for each scientific target, and 3) carried out various borehole experiments. LWD has been more popular than wireline logging in Chikyu expeditions, because its advantages match theirs science targets. The advantages are followings. 1) LWD has more opportunities for measurement in unstable borehole, such as in the series of Nankai trough drilling expeditions. 2) LWD realtime data allows us to make realtime interpretation and operational decision. Realtime interpretation was required to set obsevartory at the properposition. 3) LWD before coring allows us to make a strategy of spot coring.We can design coring intervals for our interest and core length to improve core recovery.Riser drilling brings us merits for logging. One is hole stability (good hole condition) and the other is the use of large diameter tools. Controled drilling mud in riser drilling system prevent mud invasion to formation and mitigates collapse of borehole wall. They reduce the risk of tool stack and improve data quality. Large diameter of riser pipe enhances variation of tool seizes. A couple of new tools were used for new measurement and improvement of the data quality. For example, SonicScanner (trademark of Schulumberger) successfully measured compressional and share velocity in very low velocities at the soft sediment, where it has been difficult to measure them with conventional DSI tool (Exp319). The stress and pore pressure in the borehole were measured with the wireline logging tool, (Schlumberger MDT). The single probe tool enable to measure temporal formation fluid pressure. The double packer tool enable to fracture test by sealing and pumping in the

    Escherichia coli abatement was studied in liquid phase under visible light in the presence of two commercial titania photocatalysts, and of Fe- and Al-doped titania samples prepared by high energy ball-milling. The two commercial titania photocatalysts, Aeroxide P25 (Evonik industries) exhibiting both rutile and anatase structures and MPT625 (Ishihara Sangyo Kaisha), a Fe-, Al-, P- and S-doped titania exhibiting only the rutile phase, are active suggesting that neither the structure nor the doping is the driving parameter. Although the MPT625 UV-visible spectrum is shifted towards the visible domain with respect to the P25 one, the effect on bacteria is not increased. On the other hand, the ball milled iron-doped P25 samples exhibit low activities in bacteria abatement under visible light due to charge recombinations unfavorable to catalysis as shown by photoluminescence measurements. While doping elements are in interstitial positions within the rutile structure in MPT625 sample, they are located at the surface in ball milled samples and in isolated octahedral units according to (57)Fe Mössbauer spectrometry. The location of doping elements at the surface is suggested to be responsible for the sample cytotoxicity observed in the dark.

    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.

    Full Text Available The IODP Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE will, for the fi rst time ever, attempt to drill into, sample, and instrument the seismogenic portion of a plate-boundary fault or megathrust within a subduction zone. Access to the interior of active faults where in situ processes can be monitored and fresh fault zone materials can be sampled is of fundamental importance to the understanding of earthquake mechanics. As the December 2004 Sumatraearthquake and Indian Ocean tsunami so tragically demonstrated,large subduction earthquakes represent one of the greatest natural hazards on the planet. Accordingly, drilling into and instrumenting an active interplate seismogenic zone is a very high priority in the IODP Initial Science Plan (2001. Through a decade-long series of national and international workshops, a consensus emerged that the Nankai Trough is an ideal place to attempt drilling and monitoring of the seismogenic plate interface. The fi rst phase of NanTroSEIZE drilling operations has now been scheduled for the late summer of 2007. It involves parallel deployment of both the new U.S. Scientifi c Ocean Drilling Vessel (SODV, this volume and the riser drilling vessel Chikyu.

    We present results of electrical conductivity and P-wave velocity measurements in discrete samples processed onboard Chikyu during Nantroseize expeditions 315 and 316 in the Mega Splay fault and Frontal Thrust of the Nankai accretionary prism. Quasi cubes of 20 mm thickness nominally saturated with seawater were measured across the three parallel sets of faces, first for electrical conductivity, then for P-wave velocity. Average properties and their anisotropies appeared to show some sensitivity to both lithological and fault related features. Overall, strong transverse anisotropy due to sedimentary compaction was observed for both properties with minimum electrical conductivity and P-wave velocity along the vertical core axis direction. Within the horizontal plane perpendicular to the core axis, slight anisotropies were also measured, which are likely related to tectonically driven horizontal shortening, affecting noticeably the original compaction fabric. In order to get some structural insight, samples were reoriented in our laboratories using alternative field demagnetization technique and the in-plane (i.e. perpendicular to the core axis) data rotated accordingly. For the P-wave anisotropy, initial cubes were shaped into polyhedrons in order to get even more accurate estimates. These additional measurements allowed for retrieving for each sample the 3 principal values and vectors of the best fitting ellipsoidal function. Resulting stereoplots were then compared with electrical resistivity, magnetic susceptibility (AMS) and structural data.

    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

    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

    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.

    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.

    We investigated microbial communities and biogeochemical processes in mud-volcano subsurface sediments down to 20 meters from the summit, obtained from the Kumano forearc basin in the Nankai Trough during the CK09-01 D/V Chikyu training cruise in 2009. The cored sediments contained several methane hydrates. Chemical characteristics of pore fluid indicated that the fluid in the mud volcano was supplied from the accretionary prism beneath the forearc sediments probably through faults. The cored sediments contained relatively low population of microbial cells (sediment depth (from -41 to -22%), synchronous to the increase of δ13CDIC. The significant isotopic fractionation between DIC and acetate (54.0±6.9%) indicates that the principal process producing acetate is homo-acetogenesis via the reductive acetyl-CoA pathway. Radioactive tracer experiments exhibited relatively high activities of homo-acetogenesis (14-34,900 pmol/cm3/day) compared to that of hydrogenotrophic methanogenesis (0.6-128 pmol/cm3/day). In ordinary marine sediments, homo-acetogenesis from H2 and CO2 is thermodynamically inhibited because H2 concentrations are maintained at low levels less than several nM. However, the homo-acetogenesis was thermodynamically favorable in the cored sediments because of the high concentration of H2 (>560nM). These results showed that homo-acetogenesis is dominant in the sediments around the summit of the mud volcano, while active hydrogenotrophic methanogenesis has been occurred in a deeper depth, and most portion of methane formed methane hydrates was supplied from the deep active methanogenic zone.

    Near-infrared (NIR) high-resolution spectroscopy is a fundamental observational method in astronomy. It provides significant information on the kinematics, the magnetic fields, and the chemical abundances, of astronomical objects embedded in or behind the highly extinctive clouds or at the cosmological distances. Scientific requirements have accelerated the development of the technology required for NIR high resolution spectrographs using 10 m telescopes. WINERED is a near-infrared (NIR) high-resolution spectrograph that is currently mounted on the 1.3 m Araki telescope of the Koyama Astronomical Observatory in Kyoto-Sangyo University, Japan, and has been successfully operated for three years. It covers a wide wavelength range from 0.90 to 1.35 μm (the z-, Y-, and J-bands) with a spectral resolution of R = 28,000 (Wide-mode) and R = 80,000 (Hires-Y and Hires-J modes). WINERED has three distinctive features: (i) optics with no cold stop, (ii) wide spectral coverage, and (iii) high sensitivity. The first feature, originating from the Joyce proposal, was first achieved by WINERED, with a short cutoff infrared array, cold baffles, and custom-made thermal blocking filters, and resulted in reducing the time for development, alignment, and maintenance, as well as the total cost. The second feature is realized with the spectral coverage of Δλ/λ 1/6 in a single exposure. This wide coverage is realized by a combination of a decent optical design with a cross-dispersed echelle and a large format array (2k x 2k HAWAII- 2RG). The Third feature, high sensitivity, is achieved via the high-throughput optics (>60 %) and the very low noise of the system. The major factors affecting the high throughput are the echelle grating and the VPH cross-disperser with high diffraction efficiencies of 83 % and 86 %, respectively, and the high QE of HAWAII-2RG (83 % at 1.23 μm). The readout noise of the electronics and the ambient thermal background radiation at longer wavelengths could be

    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.

    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/). 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

    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.

  19. New technologies and the Mission Specific Platform approach

    McInroy, D.; Smith, D.; Freudenthal, T.

    2009-04-01

    Within the Integrated Ocean Drilling Program (IODP), ECORD-operated Mission Specific Platforms (MSPs) have allowed scientific ocean drilling to recover core from targets that are generally inaccessible to the two dedicated IODP platforms: the US-operated JOIDES Resolution and the Japanese-operated Chikyu. By contracting vessels, drilling and logging services on a case-by-case basis, IODP has used MSPs to successfully conduct expeditions in the high Arctic Ocean and around Tahiti, and has shown that the program can recover cores in ice-covered waters and in very shallow water. The key strength of the MSP approach is that vessels, drilling and logging systems can be contracted to meet the particular needs of a scientific proposal. Within IODP, MSPs carry the necessary staff and equipment to recover and curate the core, to carry out initial descriptions, undertake a tailored downhole logging program and conduct essential measurements of physical and ephemeral properties. Comprehensive description and analysis of the cores to IODP standards takes place after the offshore phase has ended at the IODP Bremen Core Repository (BCR) in Germany. Depending on availability and cost, potentially any vessel, drilling or logging system can be hired to conduct an MSP. Future possibilities may include the Aurora Borealis that is currently being planned as an ice-breaking drilling vessel with the capability to penetrate 1000 m in 5000 m of water. The concept of MSPs could also be widened beyond vessels with conventional drill rigs. New and alternative technologies can be contracted as part of an MSP Expedition, for example remotely-operated shallow rock drills like MeBo (developed by the MARUM - Center for Marine Environmental Sciences) and the BGS Rockdrills (developed by the British Geological Survey). Such technologies have many advantages: they can be quickly deployed from a range of research and industry vessels, they can operate in a wide range of water depths (up to 6000 m by

    2015-12-01

    Since the first deep biosphere-dedicated Ocean Drilling Program (ODP) Leg 201 using the US drill ship JOIDES Resolution in 2002, scientific ocean drilling has offered unique opportunities to expand our knowledge of the nature and extent of the deep biosphere. The latest estimate of the global subseafloor microbial biomass is ~1029cells, accounting for 4 Gt of carbon and ~1% of the Earth's total living biomass. The subseafloor microbial communities are evolutionarily diverse and their metabolic rates are extraordinarily slow. Nevertheless, accumulating activity most likely plays a significant role in elemental cycles over geological time. In 2010, during Integrated Ocean Drilling Program (IODP) Expedition 329, the JOIDES Resolutionexplored the deep biosphere in the open-ocean South Pacific Gyre—the largest oligotrophic province on our planet. During Expedition 329, relatively high concentrations of dissolved oxygen and significantly low biomass of microbial populations were observed in the entire sediment column, indicating that (i) there is no limit to life in open-ocean sediment and (ii) a significant amount of oxygen reaches through the sediment to the upper oceanic crust. This "deep aerobic biosphere" inhabits the sediment throughout up to ~37 percent of the world's oceans. The remaining ~63 percent of the oceans is comprised of higher productivity areas that contain the "deep anaerobic biosphere". In 2012, during IODP Expedition 337, the Japanese drill ship Chikyu explored coal-bearing sediments down to 2,466 meters below the seafloor off the Shimokita Peninsula, Japan. Geochemical and microbiological analyses consistently showed the occurrence of methane-producing communities associated with the coal beds. Cell concentrations in deep sediments were notably lower than those expected from the global regression line, implying that the bottom of the deep biosphere is approached in these beds. Taxonomic composition of the deep coal-bearing communities profoundly

    The main goal of IODP Expedition 337 was the identification and characterization of the deep coal bed biosphere and hydrocarbon system off the Shimokita Peninsula (Japan) in the northwestern Pacific using the D/V Chikyu. To accomplish this scientific objective, it was also necessary to investigate the inorganic biogeochemistry in order to identify possible electron acceptors and bio-essential nutrients. These biogeochemical parameters greatly influence both, the composition and abundance of microbial communities as well as the organic carbon cycle. In turn, the microbially mediated carbon cycle influences the diagenetic reactions in the subsurface, thus, altering geochemical and physical characteristics of the material. Here we present results from metal and sulfur geochemical analyses from the deep-subsurface sediments (about 1250 to 2466 mbsf) at Site C0020 off Shimokita. The measured concentrations of acid volatile sulfur (AVS) as well as chromium reducible sulfur (CRS) reflect the alteration of iron oxides to iron sulfides and indicate that the main sulfur-bearing phase in the investigated sediments is pyrite. Concentrations of intermediate sulfur species are minor and occur mainly in the coal-bearing interval. Our data show that the uppermost sediments contain higher amounts of pyrite (up to 1.2 wt.%) with an average of 0.5 wt.% compared to the deeper deposits (below about 1800 mbsf), which show an average of 0.16 wt.%. In contrast, iron oxide concentrations are highest in the deeper sediment sections (up to 0.4%), where pyrite concentrations are low. The alteration of iron oxides to sulfides in theses lower section was probably governed by the amount of available sulfide in the pore water. The occurrence of (bio-)reactive iron phases in these deeply buried sediments has implications for the deep biosphere as those minerals have the potential to serve as electron acceptors during burial, including reactions involving deep sourced electron donors, such as

    During the International Ocean Discovery Program (IODP) Expedition 348, which is part of the Nankai Trough Seismogenic Zone Experiment (stage 3), the drilling vessel Chikyu advanced the deep riser hole at Site C0002, located 80 km offshore of the Kii Peninsula (Japan), from a depth of 860 meters below sea floor (mbsf) to 3058.5 mbsf. Underlying the Kumano Basin sediments, the Nankai accretionary prism appears, below 975.5 mbsf. It accreted during Upper Miocene to Pliocene times and is formed mainly by turbiditic silty claystone with rarely observed sandstone intercalations. Cuttings from both the 1-4 mm and >4 mm size fractions were investigated, showing slickenlined surfaces and deformation bands together with carbonate veins throughout the entire section from 1045.5 until 3058.5 mbsf. A scaly fabric is increasingly observed below approximately 2400 mbsf. Clay-rich cuttings were selected at different depth for specific SEM-EDS analysis, in order to investigate the initiation and development of the slickenlined surfaces, from both a structural and mineralogical point of view. Two end-members of the slickenlined surface types were observed: a) isolated smooth and uniform planes, between 20 and 50 μm long, formed by single grains of smectite with marked lineations and frequently jagged boundaries and b) microfaults (longer than 100 μm) with sharp boundaries to the undeformed rock, formed by aggregates of illite and smectite and with a well-developed lineation. In transition between these two end-member types, planes that are apparently unconnected draw a single plane and show subparallel lineations. Concerning the orientation of the slickenlines, it seems to be coherent with that observed in an array of conjugated faults, i.e. all the slickenlines belong to the same plane, in turn sub-perpendicular to the intersection of conjugated planes. These observations suggest that the slickenlined surfaces initiated along single grains of smectite and that with increasing

    Scientific ocean drilling has traditionally been conducted within a framework of international programmes. The current phase, IODP (Integrated Ocean Drilling Program), started in 2004. As opposed to its predecessors, IODP has a multiplatform approach allowing to encompass most oceanic environments and therefore expands the scientific opportunities. USA operates the non-riser vessel JOIDES Resolution. Japan operates the Chikyu, a vessel specially built for scientific purposes and equipped with a riser system that allows drilling in unstable formation and down to ~6 km beneath the seafloor. The creation of ECORD (European Consortium for Ocean Research Drilling), consortium of 16 (now 17) European countries and Canada that joined IODP as a single member, made possible the development of the concept of Mission Specific Platforms (MSPs). MSPs are platforms of opportunity contracted on a case by case basis that have allowed scientific ocean drilling to recover cores from ice-covered and shallow water targets that are generally inaccessible to the two dedicated IODP platforms. The current phase of IODP is ending in September 2013 and the new phase of ocean drilling is being prepared. A new science plan, elaborated by the international science community, was released in June 2011: http://www.iodp.org/Science-Plan-for-2013-2023/. The three current major players (USA, Japan and ECORD) are willing to participate in the next phase and continue providing access to all three platforms, although final funding decisions are still pending at the national level. The new organizational framework for scientific ocean drilling will be streamlined for a more efficient proposal review system and a better use of resources. An international evaluation for drilling proposals will be maintained, but the platforms will be operated independently by the country/consortia providing them. At the ECORD level, the new organisation may secure more funding for MSP operations and the goal is to

    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

    objectives related to the MSC. Among these proposals, one will be fully dedicated to the MSC event. Improved quality of seismic data has allowed important advances in the recognition and understanding of MSC seismic markers (surfaces and depositional units) and lithological and stratigraphical calibrations are now critical. Therefore, the drilling strategy must include multiple sites covering representative locations of both Western and Eastern Mediterranean basins. A series of critical drilling targets were thus identified as follows: - A first set of drilling targets, dedicated to shallow water (2500m) of both the eastern and western Mediterranean basins. This will be possible thanks to R/V Chikyu riser drilling vessel and will be the scope of a second MSC IODP proposal. DREAM Team: A. Giovanni galod@locean-ipsl.upmc.fr, H.

    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.
