    As to the implementation of 'the model project for effective utilization of blast furnace gas pressure energy' and the possibility of spreading the said technology, survey/study were conducted, and the results were reported. The enterprise implementing the model project, Steel Authority of India Limited (SAIL), has been investing a total of 300 billion yen in modernizing facility/equipment after the liberalization in 1992, which is a cause of a large amount of deficit. About SAIL' cash flow, it is expected that SAIL will go into the black after tax in and after 2002. Local financial institutions are careful in investing in the iron/steel industry, but they have no problems in their own financing ability. In the evaluation of economical efficiency on the commercial basis, it is difficult to implement this model if using power prices, customs duties and borrowing rates in India as conditions. However, when preferential measures such as the exemption from taxation and help to borrowing rates are taken for energy conservation facility/equipment and the cost reduction is realized by technical cooperation, etc., it will be possible to recover the investment in 5 years. As to the possibility of spreading this model, the blast furnace with a capacity of 1000{sup 3} or more is targeted, and the number of the targeted blast furnace is 23. (NEDO)

    The fate of the Russian oil concern Yukos seems to be sealed. The former rising star of the Russian energy firmament seems to be dying under the pressure of local state administration. Tax arrears, the fact that the owner Mikhail Khodorkovsky was jailed and the company placed under forced administration reflects the conflict between business and political interests in Russia. And the conflict also has an impact on Slovakia. In the portfolio of Yukos Finance, the Dutch subsidiary of Yukos, are assets that are very attractive for Russian oil concerns. One of them is the Slovak operator of the Druzba pipeline, Transpetrol. Yukos Finance owns 49% of the company's shares. Last year, the company signed a contract with the Russian oil company Russneft on the sale of the stake for 103 mil. USD. According to a contract signed in 2002 that stipulated the conditions under which the Slovak state sold the Transpetrol shares to Yukos for the next 5 years such a step has to be approved by the Ministry of Economy. The Dutch company can also sell the shares without such an approval but then it has to pay a penalty fine. In such a case Slovakia would get 50% of the original amount, i.e. 37 mil. USD. (author)

    Described herein are the FY 1999 results of the feasibility study on the blast furnace top pressure recovery turbine (TRT) technology in China. Government of China is promoting the steel industry policies to weed out outdated, inefficient production systems while preparing the priority guidance list to promote introduction of advanced technologies, for which the government is implementing or planning the preferential measures, including exemption from the import taxes and VAT, and subsidization of interest on investment. This feasibility study predicts the commercial based investment in the case where the dry dust collector and TRT that are the principal components of a dry type TRT system are manufactured in China and its acquisition ratio is increased on the condition that a suitable number of the systems are installed and on the premise that a dissemination model project is implemented. The results indicate that the system can be introduced at a cost a little less than 60% of the predicted investment in the dissemination model project. The cost-effect ratio varies with power price, which widely varies by region in China, and the dissemination feasibility is studied over a wide range of power price. The system has high dissemination potential, because almost all of the Chinese steel makers will have a sufficient cost-effect ratio which satisfies their investment standards, if they are granted the preferential measures from the government.

    On advanced work and use techniques for wood, the aseismic property of plywood-nailed bearing walls was analyzed by seismic response experiments on an excitor resulting in the sufficient aseismic property beyond usual design specification, and the load deformation model was proposed based on experimental results. The evaluation method of heat insulation for wood houses was also developed, and the simple estimation method of room temperature change and the index for evaluating heat insulation for every structure were proposed. On advanced modification and use techniques for constituents of wooden resources, the chemical structure of saponin in woods was studied together with the relation between the chemical structure and biological activity of unknown saponins synthesized from triterpene. The pervaporation property of organic composite films composed of chitinous substances and cellulose derivatives from natural polymers was also studied to develop pervaporation films effective in separating water from ethyl alcohol. 11 figs., 3 tabs.

    As an energy conservation method for a model building, the following eight methods were selected and trially calculated of the effects. 1) adoption of high efficient illumination apparatus, 2) introduction of an illuminance control system, 3) cooling water secondary pump with invertor, 4) ventilation control for parking lots, 5) heightening of the established temperature, 6) improvement of the 24-hour run chiller, 7) elevator with invertor, and 8) introduction of the photovoltaic power generation. As a result, it was found out that energy was totally reduced by about 3,837.4 MWh/yr or 25.6%. If viewed from the amount of reduction in greenhouse gas, the amount of CO2 emitted from office buildings, approximately 0.22 million t-C/yr, decreases to approximately 0.16 million t-C/yr. Further, approximately 0.93 million t-C/yr, the amount of CO2 emitted from commercial use facilities such as office buildings, department stores and hotels is reduced to about 0.69 million t-C/yr, thanks to the effect of the project on energy saving buildings, which made a CO2 reduction by approximately 0.24 million t-C/yr possible. Validity of the project on energy conservation in Indonesia was confirmed. 2 refs., 55 figs., 38 tabs.

    From the viewpoint of energy utilization stated above, blast furnace top pressure recovery turbine (TRT) unit installability was studied at Bhilai Steel Works of Steel Authority of India, Ltd., Bokaro Steel Works of Steel Authority of India, Ltd., and Visakhapatnum Steel Works of Rashtriya Ispat Nigem. The energy consumption rate at an Indian steelmaking plant is 8Gcal/t-steel, which is larger than 5-6Gcal/t-steel of Japan and therefore needs improvement. Out of the blast furnaces in India, 26 are larger than 1,000m{sup 3}, and two of them are provided with a TRT device of now-defunct Soviet Union manufacture. The blast furnaces were examined for pressure at the top, amount of gas at the top, amount of dust, and safeness in operation. The No. 2 blast furnace of the Borkaro plant was selected for the project, and studies were made for a wet type TRT device. Improvements to be achieved by TRT device installation were calculated to be a TRT output of 5,900kW, power output of 49,100MWh/year, saved crude oil amount of 12,990toe/year, and CO2 reduction of 40,200 tons-CO2/year.

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

    As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

    Mitsui Kushikino Mine previously processed two gold ores from Kushikino and Iwato ore deposits by the all slime cyanidation method, where the ores were ground to fine size smaller than 75 {mu}m and leached with sodium, cyanide. A large amount of slimes were produced as waste and discarded in tailings ponds. To save the costs of grinding and waste treatment it is desirable to process coarse sized ores. The Iwato ore is gold and silver bearing silicified porous rock. As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0 mm feed. These results showed that the gold dissolution rate was similar to that by the all slime cyanidation and the decrease in gold recovery was a few %. The properties of these tailings can be used in fine aggregate of concrete. Based on the results vat leaching of the Iwato ore was adopted in the plant. The tailings are sold and used as fine aggregate. Utilization of slime tailings from the other ores was also developed and they are used as flux in copper smelters. Now, there is no tailings pond at Mitsui Kushikino Mine. 9 refs., 10 figs., 5 tabs.

    In order to utilize more effectively coal ash whose generation amount is increasing year after year, studies have been made on a technology to manufacture and utilize a high-strength substance solidified under normal temperature by utilizing hydration reaction of pozzolan system (Poz-O-Tec). The study works have been done as a subsidy operation of the Agency of Natural Resources and Energy, and were completed in fiscal 1995. Poz-O-Tec is a wet powder made of coal ash and stack gas desulfurization sludge (gypsum) added and mixed with lime and an adequate amount of water, which solidifies by hydration as pozzolan does. The same method as used for ordinary sands may be used as the basic application method. Because this is the material whose strength increases after construction, thickness of construction may be reduced smaller than in constructions using soils and sands. Test constructions of about sixty cases have been carried out to date, typically represented in use as a road bed material, banking, and a base material for water-barrier gutters. High-strength solid material which is stable under normal temperature may be obtained by adjusting calcium content. As a result of its effectiveness in practical use having been verified, a certificate of technological judgment has been issued for the material by the Civil Engineering Research Center. 3 refs., 11 figs., 2 tabs.

    As for a preventive countermeasure against the global warming, experiments and studies have been conducted on the bioreactors to fix carbon dioxide gas recovered from the concentric and large scale generating sources such as thermal power plamts in a form of carbohydrate by means of the culture of microbial algae. By using the Vertical Tube Reactors (VTR) culturing apparatus, a variety of microbial algae were cultivated and experiments were performed on the relationship of biomass productivity and absorption rate of carbon dioxide gas indoors and outdoors. Consequently, it was found that when the flow rate of carbon dioxide gas is adjusted to make the biomass productivity of filament type Nostoc maximum,the inlet and outlet concentrations of carbon dioxide gas were 0.7% and 0.05% respectively with the absorption rate of more than 90%. From the standpoint of fixation and effective utilization of carbon dioxide gas, the above rate of removal is one of the important parameters and it will be necessary in future to compare the rates of removal of carbon dioxide gas among various types of bioreactors as a function of operating condition. 9 refs., 6 figs., 2 tabs.

    Discussions are given on treatment methods that can utilize scallop cultivation wastes effectively. Tests to incinerate and convert the main scallop shell content, calcium carbonate, into calcium oxide (CaO) discovered optimal incinerating conditions of a temperature at 750[degree]C and a duration for 30 minutes, and 700[degree]C and one hour. CaO content in burnt shells was so high that they could be used as a raw material for quick lime. In the incineration and conversion tests on wastes from shell processing factories, the result of X-ray diffraction in chemically combined conditions of inorganics before and after the incineration revealed that the main component Ca existed as CaCO3, which may be converted into CaO when incinerated. The result also showed that the second component, Mg, existed as MgO after the incineration. From the above results, incinerating the wastes from shell processing factories at 750[degree]C would be capable of incinerating organic components completely and reducing their weights. Because the inorganic residues have high CaO content, they could be utilized effectively as a quick lime raw material. Although shells to be incinerated have low salt content because of having been boiled, salt content in scallop processing factory wastes will require discussions on possibilities of its corroding an incineration furnace. 3 figs., 7 tabs.

    The feasibility study was conducted on a model project in Vietnam, aimed at solving the environmental pollution problems resulting from use of coal by demonstrating and disseminating the Japan's environmental technologies in the Southeast Asian countries. The feasibility study was conducted for the Cua Ong Coal Preparation Enterprise, which has the largest coal preparation capacity in Vietnam and port facilities. It is treating raw coal from 10 coal mines for classification and preparation, and shipping coal of various types that meet the standards for domestic use and export. The survey results point out that unrecovered coal remains in waste water discharged from the coal preparation plants to pollute the sea area, and that quantity of the refuse increases because of the unrecovered coal it contains. The environmental technologies needed to introduce include modification to variable wave pattern type jigging separator, refuse height measuring instrument and automatic controller, circulating heavy medium gravimeter, highly functional settling pond, and flocculent facilities.

    The serological HLA types (A, B, C and D loci) were studied in five different Indian groups in Colombia. The range of polymorphism was not very restricted in these groups, but there was significant genetic heterogeneity among the five populations in all the HLA loci. The gene frequency data, when converted into a kinship matrix and a two-dimensional eigen vector plot, showed a closer affinity between Bari and Yuko Indians, while Guane, Tunebo and Paez Indians were not only genetically different from the former but also well-differentiated from each other. It seems therefore from this study that geographical proximity may play a greater role than linguistic similarities in the genetic affinities of Colombian Amerindians.

    The paper outlined the present situation of industrial waste all over Japan and the present situation of industrial waste of large urban areas where it is most difficult to secure places for the final disposal, and conducted an analysis on the present and future amount of final disposal waste. According to the literature from the Ministry of Health and Welfare, `research report on the discharge/treatment situation of the industrial waste` and `research results of administrative organizations for industrial waste,` the situation of final disposal from the past to the present was outlined and analyzed to study the future trend. Out of the administrative divisions of Japan, four divisions, which are all typically called large urban areas, were selected, and the situation of industrial waste in large urban areas was outlined and analyzed according to the questionnaire survey and the literature on industrial waste obtained from each administrative division. The survey by the Ministry of Health and Welfare indicated that the volume of the industrial waste discharged from the whole country amounted to approximately 400 million tons in fiscal 1992. However, helped by the improving recycling of waste construction materials, the amount of final disposal around 2000 is presumed to be less by 20% or so than that in 1992. 58 refs., 5 tabs.

    For the establishment of a practical process for substitute natural gas (SNG) production, technological and economical assessments were made, and tasks to discharge for the development were discussed. In this fiscal year, the results of surveys conducted in the past five-year period were compiled, and studies were made to prepare for a smooth transition to the element research stage. Findings obtained are described below. SNG producing technologies need to be developed, with the demand for SNG increasing sharply, to further stabilize the base for SNG supply; coal which is abundantly available should be used as the material for SNG; and coal hydrogasification, among various methods for producing SNG from coal, is the most suitable in view of efficiency and cost performance. It was also found after a prolonged study for the improvement of efficiency and cost performance that probabilities were high that the yield of BTX (benzene, toluene, xylene) would increase and cost performance would improve. Besides, a basic plan and an element technology research plan were prepared for the development of the ARCH (advanced rapid coal hydrogasification) process. (NEDO)

    The status of the methane generation due to landfill with waste has been analyzed to investigate the actual circumstances of effective utilization of methane in the world and its possibility. The artificial generation of methane is 375 Tg per year among the total methane generation in the world, 535 Tg per year. The methane generation from the landfill with waste is 40 Tg per year, which becomes a rather large contribution. The methane generation from the landfill with waste in Japan is estimated to be from 130 to 520 Gg per year, which is a rather low value as a share in the world. This is caused by the sub-aerobic property of landfill in Japan, and the methane generation can be suppressed. Accordingly, there are no systems using recovered methane as energy source in Japan. In the USA, profitability of energy recovery can be established in 600 to 700 landfills among about 6,000 landfills. The methane recovery is practically conducted at more than 120 landfills. The recovered methane is used as a power generation fuel. 45 refs., 43 figs., 27 tabs.

    The Back Ho oilfield is the largest oilfield in Vietnam and at the same time is producing the largest amount of natural gas (associated gas) in Vietnam. Although the majority of the associated gas has been used in the power generation plant, a large amount of surplus gas is not effectively used because of shortage of fund and technologies. Accordingly, a feasibility study has been executed for a project to compress 20% of the associated gas into CNG, and use it effectively as automobile and factory fuel. As a result of the site survey, it was found that, although Vietnam consumes less amount of energy and emits less amount of CO2, the nation has a strong interest and a large amount of knowledge about global warming and CDM because the country is subjected to large effect of warming. Furthermore, it has been reconfirmed that introducing CNG into this territory is highly effective. Discussions have been made on places of installing the facilities, effective surplus gas utilization systems, facility specifications, utilities, and number of workers. Calculations were made on approximate cost of the facilities and the running cost. As a result of the surveys and discussions, it was determined that technological support from Japan and the Yen loan for environment with low interest rate are necessary. (NEDO)

This project studies effective utilization of low-quality biomass resources now discarded, e.g., thinning materials and demolition woods, by reference to biomass utilization pursued in European and North American countries. The study activities cover the 3 areas of woody biomass wastes, current status of biomass utilization technologies in the overseas countries, and feasibility of introduction of the utilization technologies, after investigating necessity of abatement of the green-effect gases, current status of energy demands and policies, and woody biomass. Utilization of biomass resources for low-temperature heat purposes, which is the central issue in Japan, is not well established both technologically and politically. Moreover, the biomass resources are not exposed to price competition. Based on these premises, a total of 6 scenarios are proposed to promote utilization of biomass resources, including power/heat co-generation at a wood processing center, and dual firing at existing coal-fired boilers.

    This survey focused on the end of the more promising companion and promoting the international cooperation on chemical CO2 fixation and utilization technology. As a result, the way of the carrying-forward of the international cooperation with more than one companion could be arranged beforehand. It led to getting an arrangement about a secrecy agreement respectively with Lurgi company and ABB company in Europe, and to providing a catalyst sample developed by RITE to implement an examination by the other party and to show related technical information. In addition, it concluded a cooperation agreement about a total system of the chemical CO2 fixation and utilization technology and methanol synthesis with ZSW. In Australia, negotiation about international cooperation with CSIRO which is a federal research organization and CRC (Cooperative Research Centre) for renewable energy has been started. The ideal circumstances are being ready for the chemical CO2 fixation project for which the international cooperation with the country where the natural energy is rich like Australia is essential when coming to practical use. To do alternating current with further high density in the following year it is desired to build a concrete study cooperation system. 1 fig., 4 tabs.

    Efforts are made under this project to develop a wastewater treatment/regeneration system, easy to operate and maintain and low in cost, jointly with a Philippine research institute. Technologies are transferred to this institute concerning research and development, system designing, operation, maintenance, and management. The goal is to disseminate such technologies in the Philippines. As for fiscal 1999 endeavors, emphases are placed on the items described below. The Container Corporation which regenerates waste paper and the RAM Food Corporation which manufactures canned foods and pickles are selected as the sites for pilot plant research. Wastewater discharged by the two corporations is subjected to laboratory-scale wastewater treatment (combination of aerobic/anaerobic treatment and activated carbon adsorption), by which a pilot plant wastewater treatment process is determined and designing conditions are defined. As for activated carbon for advanced wastewater treatment, a fine grain sample, which is the lowest in price among activated coconut shell charcoals produced in the Philippines, is acquired, and tested for performance. A wastewater treatment pilot plant is complete at the Container Corporation, and has started operation. (NEDO)

    Shortcomings of solar energy are that it is subject to weather and is not available in the nighttime. The weak points may be effectively made up for when solar energy collected on a fine day is stored in the form of hydrogen energy for recovery as required. In this report, power generated by solar cells is used for the electrolysis of water for the generation of hydrogen. The amounts of the thus-generated hydrogen and hydrogen energy are determined and, on the basis of the measured amount of insolation, the solar energy availability rate (hydrogen conversion performance) is calculated. The amount of hydrogen generated in fiscal 1996 is also calculated for every month. The hydrogen generation level is quite low in the TiO2 wet type solar cell, approximately 0.2% at most. The current efficiency is fairly high in hydrogen generation using electrolysis, which is approximately 96-97%. The efficiency is higher when several units of electrolyte are connected in series until the solar cell optimum voltage is attained. A linear relationship is found between the daily summation of insolation and the amount of hydrogen generated. 1 ref., 7 figs., 2 tabs.

    At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.

    With the biologically originated organic wastes (biomass) left unattended in Japan without being given effective measures as the object, effects are presented on contribution to reducing greenhouse effect gas emission and reducing environmental load, and considerations were given on scenarios to proliferate the utilization technologies. These actions were carried out upon identifying the trends inside and outside the country of developing methods and technologies to utilize them effectively as energy sources. Because of the present shortage in support from the policy aspects for regenerative energies themselves, the back-up from energy policy aspect is an urgent necessity by establishing such a law as the 'natural energy utilization promotion law' whose legislation is proposed by citizens. Appropriate useful technologies would have to be introduced into appropriate applications under such legislative support. For the time being, the 'wastes electric power generation' and 'bio-gasification power generation' systems that have been established already will be utilized. Furthermore, methanol and hydrogen will be synthesized from biomass to be used as fuel for fuel cells. Utilization of the cascade type system is advocated that uses substances sequentially from better ones to utilize woody biomass without waste. (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)

    A feasibility study is conducted for an Uzbekistani plan for effectively utilizing associated gas at its Kokdumalak Gas Field. The effort will lead to a clean development mechanism in the future. The associated gas and off-gas now being totally burnt in a flare stack will serve as raw materials for the recovery of LPG (liquid petroleum gas), NGL (natural gas liquid), etc. The amount of total investment is US$82,003,000, with US$69,739,000 borrowed and US$12,264,000 self-financed. Thanks to the products to be recovered, there will be an energy substitution rate of 168,418 tons per year in terms of oil. There will be a huge reduction of greenhouse gas emissions of 4.52-million tons per year in terms of CO2, tantamount to the discharge of a 1000MW-class power plant. Although the project will be low in profitability, with the FIRR (financial internal rate of return) on investment before tax being as low as 10.56%, yet it is desired that, in view of the expected reduction in greenhouse gas, effective utilization of associated gas, and in view of its impact on the future development of the Republic of Uzbekistan and its society, the project will be implemented as soon as possible. It is expected that the country will enjoy various tax revenues to be created, foreign exchange by importing LPG, and earnings through emission right trading involving greenhouse gas. (NEDO)

    This report describes the effective utilization of coal ash discharged from general industry (general industry ash) as improving material of construction waste soil and deodorant for poultry industry. Coal ash is characterized by the pozzolan and self-hardening properties which are not shown in soil and sand. Coal ash having a large amount of free CaO in its composition has stronger such properties. Coal ash generated from fluidized bed combustor which is a kind of combustor of coal contains a large amount of free CaO, especially, resulting in the stronger such properties. On the other hand, coal ash has water and oil absorbing property due to its porous structure. To utilize these properties, the improving material of soft construction waste soil and deodorant for poultry industry have been selected. As a result of laboratory and field tests for the former, it was found that sufficient supporting force can be obtained. Since the protection of powder splash is required at the site, a humidification system has been developed, which can protect the splash by the humidification of 5%. The price between 500 and 1,000 yen/ton is suitable for the improving material of construction waste soil. The maximum price of the deodorant for poultry industry is 10 yen/kg. 14 refs., 40 figs., 49 tabs.

    The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

    Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

    As for the collection of sensible heat, 1/3 of blast-furnace slag is treated to the purpose at the Teesside Technology Centre, Britain, but none is collected in the latter half of tapping in case there is so much slag that cooling cannot be done in time. In the case of a large blast furnace, some measures have to be contrived because molten iron comes out of the furnace intermittently. In Germany, the heat collection rate is as low as 3%, with no effort made at heat collection. In North America, desire to develop such a technology is not strong. A visit was made to the Institute of Ocean Sciences, Canada, in relation to the concept of using steel slag as a eutrophic source for marine photo-plankton. A large-scale long-term test is under way for examining the relationship between global warming and ocean current circulation. There are possibilities that Japan will enter into the project for a joint study, for example, of heavy metal elution from slag though the test fails to name slag as the direct object of study. Not only for Canada but also for any other country who faces the sea, it may be a meaningful national policy to inject some active ingredients into the sea for an increase in living marine resources. Greece is engaged in the ocean dumping of nickel slag on an experimental basis but, in view of the purpose of the experiment, Japan will not be a participant in the project. (NEDO)

    Investigations and studies are conducted seeking for a CO2 fixation method improved by utilizing the photosynthesizing function of higher vegetation. Details of higher vegetation genes are being disclosed thanks to the rapid progress of studies making use of molecular biological techniques, and the application of the genetic mechanism to scientific and technological fields is becoming increasingly feasible. In particular, the role of the CO2 fixation enzyme RuBisCO has been elucidated almost completely. It has been learned that, in terms of photosynthesizing capability, the C{sub 4} plants (corn etc.) are 2-3 times higher than the C{sub 3} plants (rice, wheat, etc.), and 5-10 times higher than the CAM plants (cactuses etc.). Studies are also under way about the rice genome so that a photosynthesizing capability so high as that of the C{sub 4} plants may be endowed the rice plant. The metabolism and control of useful substances produced in the CO2 fixation process etc. in the higher vegetation are being investigated, and it is now expected that some day such useful substances will be produced and utilized efficiently. Researches are under way into the relationship between the green leaf that is the organ that performs photosynthesis and the organ (sink) that stores and utilizes starch and sugar is in progress, and now a new field is going to open where vegetables will be fully utilized.

    This paper aims at arranging and assessing the role of themes of the technology development such as CO2 recovery, fixation and effective use in the industrial policy and the results of the development. It also aims at analyzing factors to hinder technology development in comparison with the developmental trend of technology and the role in the industrial policy in foreign countries and at considering the future role in the industrial policy and the course to be taken. Judging from the number of projects and a variety of fields of technology, it could be said that the development of the related technology in Japan is at a top level the same as that in the U.S. In the present conditions, however, most of the technologies are at the stage of the basic research. In many of the research fields except a part like EOR, it is difficult to promote the research only by economical principles, and the government as core needs to promote it. As viewed from an international point, the development/commercialization of technology such as CO2 recovery, fixation and effective use are extremely important from an aspect of not only the heightening of competitiveness in the domestic industry, but Japan's international contribution in the 21st century.

    Innovation plays an important role for Japan to flexibly utilize its achievements for the purpose of properly responding to new business environments and to secure competitiveness in the market. Japan lacks experts equipped with knowledge and ability as regards technology development and management which are necessary for the planning and creation of technologies, and is also short of institutes for raising experts. In America, technology management won an important position in the 1980s in the effort at industrial renovation, and the industry, government, and academia in a body endeavored to elevate the level steadily, continuously, and deliberately, to eventually provide a source of great propulsion and international competitiveness toward today's economic success. Investigations were conducted, and a proposition is made for the establishment of an international technology management research center. Such a center will study technology management and innovation through international exchange based mainly on the industrial circle and through the organic coordination of the industry, government, and academia for widely observing changes in international society for economic frontier cultivation. A practical training and intelligent network will be organized on the global scale, which will serve as an information transmitter. A skeleton of the plan is shown. (NEDO)

Mucin-like glycoprotein was detected in the culture supernatant by an enzyme-linked lectin assay. Gefarnate ointment was topically applied to eyes once daily for 7 days in the rabbit dry-eye model, in which the lacrimal glands, Harderian gland, and nictitating membrane were removed, or for 4 weeks in the cat dry-eye model, in which the lacrimal gland and nictitating membrane were removed. Corneal epithelial damage was evaluated by measurement of corneal permeability by rose bengal in the rabbit model or by fluorescein staining in the cat model.Results: Gefarnate stimulated mucin-like glycoprotein secretion in conjunctival tissue in a dose-dependent manner. In the rabbit dry-eye model, application of gefarnate ointment to the eyes resulted in a dose-dependent decrease in rose bengal permeability in the cornea, with the effect being significant at concentrations of ≥0.3%. In the cat dry-eye model, application of gefarnate ointment resulted in a significant decrease in the corneal fluorescein staining score.Conclusion: These results suggest that gefarnate stimulates in vitro secretion of mucin-like glycoprotein in conjunctival tissue and ameliorates corneal epithelial damage in animal dry-eye models. Gefarnate may therefore be effective for treating dry eye.Keywords: gefarnate, fluorescein staining, rose bengal permeability, rabbit, cat, dry eye

Types of the model system were selected assuming the utilization of cold heat energy of snow in Sapporo, a typical large city in the cold heavy-snow area. Studies were made on each model of urban type commercial facilities, urban type offices, suburban type shopping center, and suburban type hospitals. For each model, more than one systems were studied according to types and forms of the storage tank, and heat recovery methods. As a result, it was found that cold heat energy of snow can be utilized almost effectively by making an appropriate study of the energy balance like the possible supply of cold heat exceeded the demand in two models of an urban type office building and an suburban type hospital. Further, operating expenses of typical models were roughly calculated. 51 figs., 20 figs.

    Wastewater reuse can be considered as a type of water resource development which is expected to improve the aquatic environment, as well as the stability and reliability of municipal water supply systems. To this extent, wastewater reuse has been taken into account in the planning of water supply systems in several Japanese cities. However, to date the effect of wastewater reuse on water supply system stabilization has not been discussed quantitatively, and the relation between waster water reuse rate and water supply system stability has not been analyzed. In this study, a stochastic model has been presented to evaluate the stability of water supply systems with optimal wastewater reuse rate. Some theoretical analyses and numerical studies were performed, and all of the results have shown that the model is reliable for not only basic studies on water supply system stability, but also for practical use as well. 5 refs., 5 figs., 3 tabs.

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 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.

    Taking the area of the clean coal technology (CCT) effective for energy conservation and environment preservation as the object, a feasibility survey has been performed on executing a model project in India. About 70% of the total power generation capacity in India depends upon coals existing in abundance inside the country. Since the local coals are high in ash, low in sulfur, and low in calorie, the environmental problem related to thermal power plants is the disposition of fly ash. The Central Electricity Authority of India expects solving this problem by CCT introduction. It also expects increase in combustion efficiency by using ultra-critical boilers. The Indian cement industry often uses in-house electric power generation facilities because of high electric power cost, wherein the produced coal ash is used as a cement raw material. The matter of the strongest interest is the introduction of a high-efficiency combustion system that depends on low-grade coals. Among the CCTs, strong interest was shown in the fluidized bed cement kiln and the circulating fluidized bed boiler. The iron and steel industry has expectations toward effective coal washing technologies and coke manufacturing technologies. (NEDO)

    For the purpose of the improvement of coal utilization technology and environmental preservation, the paper conducted the pre-survey of the introduction of coke oven gas desulfurization facilities in China and pre-survey of potentiality of the environmentally friendly type coal utilization system in India. The pre-survey in China was made for Anyang Steel Group Co. Ltd. and Laiwu Steel Group Co. Ltd. to judge their adaptability as site for the demonstrative project on the introduction of coke oven gas desulfurization facilities. As a result, it was confirmed that the former satisfied the conditions on Japan side such as the space for installation and prospect for fund raising. However, the amount of COG treatment was larger than that planned at Japan side, and it was found that as to the recovered sulfur, the company wanted the solid sulfur different from the fused sulfur planned at Japan side. In the survey in India, explanations were made to India of CFBC and the fluidized bed cement sintering system, bio-briquette production facilities, facilities for environmental measures, coal reforming technology, etc. At the same time, the site survey was made to examine/analyze possibilities of spread/development of Japan's CCT.

    The early days of 2003 saw Russia and its oil sector drawing the attention of international investors, as evidenced by the joint venture between BP and TNK, Exxon Mobil's plans regarding Yukos or Shell's. Some people saw in those agreements or plans the signs of a normalisation of the Russian economy, particularly in terms of property rights. The arresting of Mr Khodorkovsky, the chairman of Yukos put a sudden stop to such optimism and comes as a reminder of a few realities. Despite the progresses made, the economic and institutional environment of the country is still unstable, as shown by the questioning of the Production Sharing Agreement Act or the increasingly demanding access to oil resources. The BP TNK agreement is not a reproducible investment model. If there is some opening it will be on the terms set by the Russian government. (authors)

    Modeling of technical machines became a standard technique since computer became powerful enough to handle the amount of data relevant to the specific system. Simulation of an existing physical device requires the knowledge of all relevant quantities. Electric fields given by the surrounding boundary as well as magnetic fields caused by coils or permanent magnets have to be known. Internal sources for both fields are sometimes taken into account, such as space charge forces or the internal magnetic field of a moving bunch of charged particles. Used solver routines are briefly described and some bench-marking is shown to estimate necessary computing times for different problems. Different types of charged particle sources will be shown together with a suitable model to describe the physical model. Electron guns are covered as well as different ion sources (volume ion sources, laser ion sources, Penning ion sources, electron resonance ion sources, and H$^-$-sources) together with some remarks on beam transport.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    Described herein are the results of the FY1994 research program for international joint technology development for solar energy utilization systems. The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

    As a part of the WE-NET project, the introduction condition of hydrogen as substituting energy and CO2 reduction effect were analyzed using a global energy model. The WE-NET project aims at global-wide introduction of clean energy by converting abundant renewable clean energy into hydrogen transportable to distant consumers all over the world. The study result in fiscal 1996 is as follows. Undeveloped hydroelectric resources in the world are estimated to be 12 trillion kWh/y equivalent to the existing developed one in the world. Since the cost of the hydroelectric power generation projects over 1000MW in the planning stage is estimated to be 0.02-0.05$/kWh lower than that of other renewable energies, such projects are expected as energy source in the initial stage of the practical WE-NET project. The GREEN model was modified by adding a hydrogen analysis function, and extending an analysis period.

    In this study, taking the all factors involved in the energy consumption in residential houses as subjects, the effectiveness of the solar PV system and solar thermal utilizing system in residential houses has been studied by simulating a model residential house considering the improvement of the residual environment in the future. Therefore, a model residual house is assumed, 18 kinds of combinations of construction style, cooling and heating type and solar energy utilizing form are assumed and year round simulation is carried out. The conclusions obtained by the simulation are as follows. The energy consumption in residential houses may decrease greatly by using a solar hot water supplying system. If combined with a solar PV system, the energy consumption in one year is about 8.7 to 9.7 MWh. The combined use of a solar thermal utilizing system and a PV system is more effective to reduce the second-time energy in comparison with the PV system only. 36% of the space heating energy consumption may be decreased by using the solar space heating system, but the decrease effect of the energy consumption of the solar space heating system is smaller than the solar hot water supplying system. 12 refs., 26 figs., 3 tabs.

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

    This paper reports the result obtained during fiscal 1994 on a survey to prepare scenario for the diffusion of photovoltaic power generating systems. Introduction target planned with help of a diffusion simulation was verified by calculations using simulation models. The calculations made the following points clear: facility costs and power generation costs for photovoltaic power generation systems, amount of introduced photovoltaic power generation systems, number of facilities introducing photovoltaic power generation systems, policy cost to achieve the target, annual power generation amount, oil substituting effect, carbon dioxide reducing effect, and market sizes. Power generation cost in fiscal 2000 would drop down to 53 yen per kWh in new installation in independent houses and down to 31 yen per kWh in systems used in schools. These reductions are the result of progress in mass production as a result of positively implementing the aiding policies. The required diffusion aiding policies revealed from the simulation results include expansion of subsidy operations for house construction, introduction of the systems into public facilities performed by public organizations, aid to system introduction into private business entities, subsidy to facility investments, and enforcement of power purchase institutions. 3 figs.

    This report provides the development of new exploration technology using elastic waves, such as reflection seismic survey, VSP, and seismic tomography, for precisely characterizing subsurface fractures in geothermal reservoirs. In order to investigate and improve the effective data acquisition and analysis methods for detecting a fault type of fractures, an experiment of a seismic tomography method was conducted using wells drilled in the Ogiri geothermal field, Aira-gun, Kagoshima Prefecture. An experiment of propagation characteristics of piezo type underground seismic source in the volcanic field was also conducted as a trend survey of underground seismic sources. The fracture type in the model field was systematically analyzed by measuring the core samples obtained in the demonstration test field through remanence measurement, fluid inclusion measurement, and zircon measurement using test equipment, and by analyzing results obtained from cores and results of seismic tomography obtained from the wells. Based on these results, the effectiveness and practical application of exploration methods using elastic waves were investigated. 80 refs., 250 figs., 49 tabs.

    The survey has given an eye to the coal that it can be easily burnt together with combustible waste and supplements unstable generation of waste. Thus, the establishment of the Energy Center at the place where infrastructure of coal will be arranged, a lot of combustible waste will be expected to generate and a considerable aniybt if energy will be used, has been planned, and this survey is intended to study the scale of Energy Center, its economy and the problems to be solved. In power plant project using RDF for above-mentioned local governments, the construction of power plant and the renewal time of the existing incinerator to RDF facility can be planned separately in this system. The power plant will be economically constructed and the amount of coal can be decreased in accordance with increased RDF to meet wide range of refuse treatment. In FY 1997, the actual situation of the waste treatment and the infrastructure of coal supply was surveyed, and selection of the place suitable for the Energy Center and its scale was studied. 69 figs., 50 tabs.

    Alpha activities as a basic component of EEG (electroencephalogram) are mainly observed with eye-closed and reported state, and indicates rhythmic and diffused pattern on the scalp. Therefore analysis of the relation among many sequences of alpha activities measured at different positions on the scalp is expected to be useful not only for diagnosing psychiatric but also for investigating mechanism of brain information processing by means of causality analysis that is, macroscopic estimation of flow pattern within brain. Although coherence analysis has been proposed as a method for estimating the direction and magnitude of information flow between two sequences, superposition of results for each pair of sequences can not represent true relation among the whole sequences. In this paper, we proposed the multidimensional directed coherence analysis by modifying two-channel formula in order to apply it to the analysis of multi-channel sequence of alpha activities. Results of simulation revealed that multidimensional directed coherence can indicate more quantitatively the relation among the multi-channel sequences compared with conventional two-channel formula. Moreover, the proposed method was applied to the analysis of EEG data of normal volunteer and patient. Results show the method can provide a useful diagnostic information by assessment of the signal flow pattern within brain. 16 refs., 10 figs.

    For the purpose of contributing to the future coal industrial policy of Japan, an investigational study was conducted on the nature of coal as resource, the production/utilization status, policies of other countries, etc. The coal demand during the period of 1991 through 1995 rapidly increased in Asia, slightly rose in North America, decreased in East and West Europe, and largely declined in the former U.S.S.R. The energy demand showed a large growth rate with the economic growth in developing Asian countries in and after the 1980s as a background. The power demand which supports the economic growth will continue to improve. It connects with the coal demand in Asia, and the coal demand seems to rapidly increase. Further, the global warming issue became a great matter of concern in the 1990s. Coal, which emits more CO2 per unit calorific value than oil and natural gas, is not a powerful candidate for petroleum substituting energy as used to be regarded, but became a bad thing. Moreover, recently the economic stagnation in Asia which was triggered by the currency crisis has long been continuing, and it started to appear that the coal consumption will possibly fall very short of the prediction. The future is unclear. 20 refs., 25 figs., 39 tabs.

    For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

    To introduce the power generation system fueled by animal waste (excrements), one of the so-called industrial waste, its feasibility has been studied in Koyu and surrounding area located in Miyazaki Prefecture. This report includes the technical feasibility of available quantity of animal waste, chemical analysis of the waste, and basic design of the power generation system containing the furnace model and also its economical feasibility. The available quantity of animal waste in Koyu area is about 169,000 tons a year, which can generate 10.5 MW of electric power. That including the surrounding area is about 219,000 tons a year, which can generate 15.0 MW. The heating values of animal excrements in average and as received are 970 kcal/kg for pigs and 1,230 to 2,700 kcal/kg for broilers. In the case of combustion of mixed broiler and pig excrements, both of the stoker and fluidized-bed model furnaces become refractory furnace construction and provide with heat recovery boiler due to their high moisture content. In addition, the stoker furnace model requires an excrement dryer system as pre-treatment of fuel. For the fluidized-bed furnace of 15 MW grade power plant using the mixed fuel of 50% broiler excrements and 50% pig excrements, the power generation efficiency of 23% can be expected at generator end. The generating cost is around 10 yen/kWh. 27 refs., 61 tabs.

    We will get Transpetrol Lubomir Jahnatek, the Minister of Economy, was full of optimism following negotiations with the representatives of the Dutch company, Yukos Finance. According to the results of the meetings, the shares should have been back in Slovakia by the end of August. This enthusiasm was premature. The negotiating power of the delegation which came to Bratislava to promise the return of Transpetrol was very weak. The managers of Yukos Finance thought they would manage to avoid communication with Eduard Rebgun, Yukos' Russian bankruptcy supervisor. Their analyses showed that Yukos Finance is legally only marginally connected with the parent company, Yukos, and that they will be able to decide on the sale of Transpetrol and the Latvian refinery, Mazeikiu Nafta, on their own. On Friday last week, the Dutch courts decided that the Russian administrator is authorized to call an extraordinary general meeting of the Dutch company and to replace its management. This has further complicated the entire situation. (authors)

    In order to identify the possibility of a hot rock power generation system, technological R and D has been performed on structuring of a man-made hydrothermal system, fracture mapping, downhole measurement and a circulating extraction system. This paper summarizes the achievements in fiscal 2000. With regard to the long-term circulating extraction test, a circulating heat extraction and test device was installed at the hot rock experimental field in the Hijiori area in Yamagata Prefecture, where geochemical data collection and tests including analyses thereon have begun. In reservoir bed analysis, a well module was incorporated into a reservoir bed simulator to improve the module so that comparison with the data of actual production on the ground can be performed. For the fracture mapping, AE having been observed during the long-term circulation test was analyzed, whereas it was estimated that the seismic source would not move or expanded during this period. A PTS logging has been performed during the long-term circulation test to investigate characteristics of the flow-out zone of the injection well and the production zone of the production well. In making the fracture model, an initial model was fabricated to estimate heat extraction behavior in the long-term circulation test. (NEDO)

As in the last fiscal year, conditions of the study of IEA/ETSAP were continuously used. It was decided on that hydrogen was produced by hydroelectric/photovoltaic power generation overseas. Prices were made 14 yen and 27 yen/103 kcal. The limit price of introduction of import hydrogen was calculated. During the period from 2030 to 2050, if the hydrogen price is less than 7 ten/103 kcal, the result showed that hydrogen can be introduced in a lot of scenarios (case of the severe control of CO2 emissions, case of high priced fossil fuels, case of the low capacity of the development of nuclear power generation, etc.) As the form of hydrogen use, promising are the hydrogen combustion turbine power generation, mixture with town gas (hythane) and hydrogen cars. However, a precondition for the introduction is that the cost of hydrogen car should be more economical than the competitive means of transportation. As to hydrogen combustion turbines and hythane, the quantity of hydrogen introduction depends little on variations of characteristics of the equipment used. 11 refs., 55 figs., 21 tabs.

    As to the development of coal use hydrogen production technology, the paper studied the reactivity of char and ignition characteristics of various coals in the use of electric furnace and the participation in pilot plant test and the improvement, and the FY 1993 results were reported. In the study of reactivity of char, it was found that the reactivity was the same, regardless of the equipment and kind of raw coal, if considered of the ratio of the total oxygen amount (the char-containing oxygen amount added to the oxygen supply amount) to the carbon supply amount in char. In the test on ignition characteristics of overseas coals, the same characteristics as those of the Taiheiyo coal conventionally tested were obtained and it was found that it was good to use the same method for start-up of gasifier as conventionally used. In the pilot plant test in the previous year, slag and ash stuck to the outlet of the gasification part and heat recovery part and developed, which hindered the continued operation. To improve it, the following were carried out: model study, study of ash sintering, study using the synthetic test equipment, analysis of the deposit in gasifier, etc. Based on these results, the plant was improved, and the continued operation of 1,149 hours was stably achieved in RUN8.

    This paper discusses hydrogen fuel cell systems. In the economic performance of fuel cells, the ratio of fuel cost accounting for in the power generation cost is as very high as 66% or higher to 82%, if hydrogen unit cost is in the range of 20 to 50 yen per Nm{sup 3}. Enhancing the power generation efficiency contributes more greatly to reduction of the power generation cost than by reducing the construction cost. There should be no much influence on the power generation cost if a system lasts four to five years. The paper also discusses the discrete type power generation system. Discussions were given on a waste heat recovering fuel cell system using as the model an office building of 16 stories above the ground, with one basement and a total floor area of 16,000 m{sup 2}. If the system can be constructed in such a way that the fuel cell capacity is made slightly larger than that corresponds to power load, and whole air conditioning load can be taken care only by waste heat by using a heat pump, the auxiliary heat source can be made smaller, and the overall fuel conservation ratio can be larger, thus the fuel was found saved by 40% than in existing systems. In using hydrogen in automobiles, weight problem will emerge if high-pressure hydrogen or metallic hydride is used for hydrogen storage. Liquefied hydrogen is light in weight, but large in volume. Development is desired on high-performance hydrogen absorbing alloys. (NEDO)

    For the purpose of smoothly introducing biogas plants to Hokkaido in the future, the following were conducted: collection of the data on samples of development/introduction of biogas plants, survey of the organizations concerned, etc., study of economical efficiency, etc. Those were arranged as a guide for biogas energy utilization in Hokkaido. In the biogas plant, organic matters such as animal faces, garbage, etc. are anaerobicly fermented at medium temperatures between 35 and 38 degrees C or at about 55 degrees C to obtain biogas including methane gas of approximately 60%. From this gas, heat is obtained by gas boiler, and also electricity and heat are obtained by gas cogeneration or fuel cells. In the case of introducing the biogas plant using animal faces as raw material in Hokkaido, it is important to cover all the electricity and heat used to maintain the plant with the biogas obtained, from a viewpoint of economical efficiency. In the present situation, it is the most economical for each farmer to introduce an individual plant to be installed and to obtain the power generated and heat. (NEDO)

    For the establishment of the basis of supercritical fluid technology, we perform elucidation of the specific feature of the supercritical fluid as a reaction media and development of some new process. In this study, we first studied the fluid structure of SCF through in-situ spectroscopy and MD simulation. As a result, significant hydrogen bonding amongst water molecules and a solvation structure around the solute were observed in the supercritical state. This fluid structure has new features different from that of high temperature steam or liquid water. We found that this is closely related to the difference of bulk properties of SCF and local one around the solute. On the basis of these fundamental findings and with the better understanding of the specific features of SCF as a reaction media, development of some new process had been conducted more efficiently and successfully. The processes being developed in this study include 1) waste biomass and plastic conversion to recover chemicals, 2) hydrogenation of heavy oil for desulphurization through partial oxidation 1 and 3) hydrothermal synthesis of metal oxide fine particles.

    Cellulose produced by bacterial is called bacterial cellulose (BC). The morphology and physical properties of BC are found to be quite unique in comparison with those of higher class plants. The properties are elucidated and a study is made to utilize the properties. The outline of this study is introduced in the sequence of BC production, BC morphology, elucidation of the physical property, and study on the application. BC consists of ultrafine fibers, and the widths of fibers are in the range from (1/199) to (1/1,000) of cotton fibers, forming distinctive network structure. It is assumed that the high Young`s modulus is based on the structural features of BC. Researches have been made on various applications to such fields as audio, paper, food, and compounds where the features of cellulose are utilized effectively. The morphology of cellulose can be varied by adding drugs which can change a part of the protein. It is expected that cellulose structure can be controlled in the future by the application of this technology. 18 refs., 6 figs., 2 tabs.

    This paper introduces the polymer dispersed liquid crystal (PDLC) ACT'' sheet, a liquid quartz light modulating film, developed by the Ajinomoto Company in Japan. A mixture of liquid crystal and polymer precursor is sandwiched between polyethylene terephthalate films imparted with transparency conductor made of indium tin oxide (ITO), which is then polymerized by heating or irradiating ultraviolet rays to obtain a PDLC. The film has a thickness as thin as about 0.3 mm, and good processibility. The sheet uses light modulating elements functioning on scatter and permeation of light. Clarification was made on the voltage dependence of cloudiness, total light permeability, straight and parallel light permeability, the response, and the operating voltage. The system consumes small amount of power with a threshold value of about 35V, and is suitable to operate large areas when working on the utility power supply. An incident light having a high diffusion capability when the electric field is turned off exhibits a high clouding function. The system gives an excellent feel of colorlessness and transparency when the electric field is turned on. The performances in heat insulation, infrared reflection capability and noise resistance are expected to be compounded for a functional versatility. 4 refs., 6 figs., 2 tabs.

    In order to develop a seawater desalination equipment utilizing solar heat, a performance test was performed on a three-stage solar heat vacuum distiller. The equipment can evaporate and condense water at low temperatures by reducing the pressure in a distilling section. Solar heat is collected by a heat collecting plate, by which water as the working fluid is evaporated and moved to a heat conducting section in an evaporation pipe in a state of steam. The steam is condensed in a low-temperature heat conducting pipe, the heat is released outside the heat conducting pipe, and seawater is evaporated under low pressure condition. The working fluid is circulated for repetitive use. Solar cells are used as a motive power source for a vacuum pump, hence the system is self-sustainable even if installed in a desert area and the like places. The construction is simple, highly durable, and easy in maintenance. The system has high water producing performance, uses no harmful substances whatsoever such as fluorocarbons, and is a friendly system to the global environment. Because of evaporation at low temperatures, heat loss to the surroundings and sensible heat due to temperature rise are small, and the system response is quick. The solar heat can be utilized more effectively as multiple effects. When a heat collecting plate of 7.76 m {sup 2} was used, maximum yield of 105.45 kg/day was obtained. The system`s distillation efficiency is higher than other types of solar heat utilizing distillers. 7 refs., 5 figs.

    This paper describes the measurement and analysis for clarifying solution structure of supercritical water and exhibition mechanism of solvent functions. It also describes the development of new processes using supercritical water as reaction solvent. The PVT measurements were conducted in the supercritical region using pure water and NaCl aqueous solution, to confirm the reduction of molar volume of the electrolyte solution. The hydration structure was examined in the supercritical aqueous solution by the molecular dynamic simulation. As a result, presence of hydrogen bond structure, where the contribution of two branching hydrogen bond can not be ignored, was suggested under the supercritical condition. Characteristics of supercritical aqueous solutions are analyzed through in-situ Raman and scattered X-ray spectral measurements. Moreover, this paper introduces developments of some processes in the supercritical water, such as decomposition of wasted polymers, recovery of chemical materials, reforming of heavy hydrocarbons by contact hydrogenation, and synthesis of fine powders of metal oxide by reaction crystallization.

    Developing experimental models to understand dental caries has been the theme in our research group. Our first, the pH-cycling model, was developed to investigate the chemical reactions in enamel or dentine, which lead to dental caries. It aimed to leverage our understanding of the fluoride mode of action and was also utilized for the formulation of oral care products. In addition, we made use of intra-oral (in situ) models to study other features of the oral environment that drive the de/remineralization balance in individual patients. This model addressed basic questions, such as how enamel and dentine are affected by challenges in the oral cavity, as well as practical issues related to fluoride toothpaste efficacy. The observation that perhaps fluoride is not sufficiently potent to reduce dental caries in the present-day society triggered us to expand our knowledge in the bacterial aetiology of dental caries. For this we developed the Amsterdam Active Attachment biofilm model. Different from studies on planktonic ('single') bacteria, this biofilm model captures bacteria in a habitat similar to dental plaque. With data from the combination of these models, it should be possible to study separate processes which together may lead to dental caries. Also products and novel agents could be evaluated that interfere with either of the processes. Having these separate models in place, a suggestion is made to design computer models to encompass the available information. Models but also role models are of the utmost importance in bringing and guiding research and researchers. 2015 S. Karger AG, Basel

    Full Text Available Today's software systems are too complex to implement them and model them using only one language. As a result, modern software engineering uses different languages for different levels of abstraction and different system aspects. Thus to handle an increasing number of related or integrated languages is the most challenging task in the development of tools. We use object oriented metamodelling to describe languages. Object orientation allows us to derive abstract reusable concept definitions (concept classes from existing languages. This language definition technique concentrates on semantic abstractions rather than syntactical peculiarities. We present a set of common concept classes that describe structure, behaviour, and data aspects of high-level modelling languages. Our models contain syntax modelling using the OMG MOF as well as static semantic constraints written in OMG OCL. We derive metamodels for subsets of SDL and UML from these common concepts, and we show for parts of these languages that they can be modelled and related to each other through the same abstract concepts.

    Observations are being made in Takasaki City, Gunma Prefecture on insolation, putting emphasis on the north side, and insolation by wavelengths to put insolation estimation model on the north side slope into order. This is an attempt to put into order by using the model the data for insolation on slope in all azimuth, taking the meteorological offices all over the country as the object. With regard to monthly average insolation, it was verified that the existing estimation model can be applied to the north slope in the Takasaki area, whereas trial calculations were performed on the average daily cumulative insolation by azimuth and inclination angle in the Takasaki observation points. As a result, it was made clear that the insolation onto north side roofs in Japan is about 70% of that on the south side. With respect to the time cumulative slope insolation, it was made clear that the Perez's cumulative model can be applied to the Takasaki area. Spectral distribution of global and scattered solar radiation was put into order by insolation to have verified that the stronger the global solar radiation intensity, the greater the occupation ratio of shorter waves increases, or in other words, the spectral distribution of the global insolation can be formulated. Sky distribution of radiation is being measured by means of measuring the sky scanning type radiation and luminance distribution. (NEDO)

    Full Text Available In this paper, the concept of locally simple models is considered. Locally simple models are arbitrarily complex models built from relatively simple components. A lot of practically important domains of discourse can be described as locally simple models, for example, business models of enterprises and companies. Up to now, research in human reasoning automation has been mainly concentrated around the most intellectually intensive activities, such as automated theorem proving. On the other hand, the retailer business model is formed from ”jobs”, and each ”job” can be modelled and automated more or less easily. At the same time, the whole retailer model as an integrated system is extremely complex. In this paper, we offer a variant of the mathematical definition of a locally simple model. This definition is intended for modelling a wide range of domains. Therefore, we also must take into account the perceptual and psychological issues. Logic is elitist, and if we want to attract to our models as many people as possible, we need to hide this elitism behind some metaphor, to which ’ordinary’ people are accustomed. As such a metaphor, we use the concept of a document, so our locally simple models are called document models. Document models are built in the paradigm of semantic programming. This allows us to achieve another important goal - to make the documentary models executable. Executable models are models that can act as practical information systems in the described domain of discourse. Thus, if our model is executable, then programming becomes redundant. The direct use of a model, instead of its programming coding, brings important advantages, for example, a drastic cost reduction for development and maintenance. Moreover, since the model is well and sound, and not dissolved within programming modules, we can directly apply AI tools, in particular, machine learning. This significantly expands the possibilities for automation and

    Simulation models are widely used in all types of hydrologic studies, and many of these models can be used to estimate recharge. Models can provide important insight into the functioning of hydrologic systems by identifying factors that influence recharge. The predictive capability of models can be used to evaluate how changes in climate, water use, land use, and other factors may affect recharge rates. Most hydrological simulation models, including watershed models and groundwater-flow models, are based on some form of water-budget equation, so the material in this chapter is closely linked to that in Chapter 2. Empirical models that are not based on a water-budget equation have also been used for estimating recharge; these models generally take the form of simple estimation equations that define annual recharge as a function of precipitation and possibly other climatic data or watershed characteristics.Model complexity varies greatly. Some models are simple accounting models; others attempt to accurately represent the physics of water movement through each compartment of the hydrologic system. Some models provide estimates of recharge explicitly; for example, a model based on the Richards equation can simulate water movement from the soil surface through the unsaturated zone to the water table. Recharge estimates can be obtained indirectly from other models. For example, recharge is a parameter in groundwater-flow models that solve for hydraulic head (i.e. groundwater level). Recharge estimates can be obtained through a model calibration process in which recharge and other model parameter values are adjusted so that simulated water levels agree with measured water levels. The simulation that provides the closest agreement is called the best fit, and the recharge value used in that simulation is the model-generated estimate of recharge.

The bankruptcy trustee of Yukos, Eduard Rebgun, has so far received three offers from Gazprom, the Rusneft oil company and the Penta private equity group via its Cyprian company. All three would like to gain control over the Slovak oil transporting company. As yet, no formal request from the Slovak Republic has been delivered to Moscow. By Trend's deadline, President Ivan Gasparovic and the Minister of Economy, Lubomir Jahnatek, were still negotiating in Moscow with the Russian President, Vladimir Putin. One of the topics on the agenda was the future of the company which transports Russian oil to Europe. Both Slovakia and Russia aim to gain control over the stock and the situation is locked in stalemate The stock in question is owned by the Dutch company, Yukos Finance. And although this company is owned by the bankrupt Yukos, the property rights are in the hands of foundation, Stichting Administratiekantoor Yukos International. Yukos Finance is not in bankruptcy and it is therefore difficult to detach the Yukos shares from the company assets. (authors)

Earlier considerations have traditionally been conducted while making a clear distinction between physically-based and conceptual models. A new philosophical account, primarily based on the fields of physics and economics, transcends classes of models and scientific disciplines by considering models as "mediators" between theory and observations. The core of this approach lies in identifying models as (1) being only partially dependent on theory and observations, (2) integrating non-deductive elements in their construction, and (3) carrying the role of instruments of scientific enquiry about both theory and the world. The applicability of this approach to hydrology is evaluated in the present article. Three widely used hydrological models, each showing a different degree of apparent physicality, are confronted to the main characteristics of the "mediating models" concept. We argue that irrespective of their kind, hydrological models depend on both theory and observations, rather than merely on one of these two domains. Their construction is additionally involving a large number of miscellaneous, external ingredients, such as past experiences, model objectives, knowledge and preferences of the modeller, as well as hardware and software resources. We show that hydrological models convey the role of instruments in scientific practice by mediating between theory and the world. It results from these considerations that the traditional distinction between physically-based and conceptual models is necessarily too simplistic and refers at best to the stage at which theory and observations are steering model construction. The large variety of ingredients involved in model construction would deserve closer attention, for being rarely explicitly presented in peer-reviewed literature. We believe that devoting

    In the general exploitation scheme, technological information is collected about cement overseas, DHM (down hole motor), etc. In the development of heat-resistant durable bits, an improved version of the 350 degrees C real bit manufactured in fiscal 1997 undergoes a test in a real bore, and is evaluated for its general performance. In the development of high-temperature cement slurries, the ultralow specific gravity cement slurry for casing cement developed in fiscal 1997 is subjected to evaluation. It is examined by chemical analysis and powder X-ray diffraction, and its fluidity, free water, rate of dehydration, and compression strength at 250 degrees C are measured. In a real bore test, a slurry of the optimum composition is prepared and then hardened, and the hardened body is kept exposed to geothermal environments for eight weeks. It is then found that the hardened body retains a compression strength of 70kgf/cm{sup 2}. In the development of a down hole motor, a scale model, real in diameter and shortened in length, is built of the motor section, and is tested in circulating water and oil at normal and high temperatures, and its behavior and performance are evaluated.

    In developing hydrogen transportation and storage technologies based on the WE-NET project under the theme of the 'development of different common devices', surveys and discussions have been performed on four themes with high urgency. It was revealed that, with respect to the large liquid hydrogen pump, the survey report should be reported on the pump models, motors, reduction of NPSH, and bearings, and that the cryogenic pump technology has a necessity of further development because the technology is biased to pumps for rocket with high head. With regard to the vacuum heat-insulated piping with large diameters, such strict problems in the technological development were made clear as high heat insulating performance, optimization of the shield structure, measures for thermal stress, anti-seismic measures, and sealing mechanism at joints, in addition to the vacuum heat insulating piping technology that has been built to date. The liquid hydrogen valve is subjected to a technological problem of the very low temperature and combustion performances of liquid hydrogen, which requires further researches. With respect to the instrumentation facilities, as a result of discussing the liquid level meter system and the flow rate meter system, it was found that there is no almighty method, whereas selection of the method should be as required in particular situation.

The FY 1988 R and D results are described. For gas-hydrate exploration, the methods for analyzing inorganic ions and trace quantities of elements, which are necessary for accurately estimating the offshore GH around Japan, are established; and case studies are conducted for methods of predicting GH deposit forming mechanisms, and stability fields of GH, based on terrestrial heat flow and seismic data. For excavation techniques, GH decomposition rate is analyzed using a laboratory system which reproduces conditions of excavation of GH layers. For methods for assessing environmental impacts, a geo-hazard predicting model is established, to study ground displacement and gas leakage sensing systems and data transmission systems to cope with the hazards. For gas hydrate handling systems, an overall system is studied, and storage and transportation systems are outlined. (NEDO)

    Three existing eclipse models for the PSR 1957 + 20 pulsar are discussed in terms of their requirements and the information they yield about the pulsar wind: the interacting wind from a companion model, the magnetosphere model, and the occulting disk model. It is shown out that the wind model requires an MHD wind from the pulsar, with enough particles that the Poynting flux of the wind can be thermalized; in this model, a large flux of energetic radiation from the pulsar is required to accompany the wind and drive the wind off the companion. The magnetosphere model requires an EM wind, which is Poynting flux dominated; the advantage of this model over the wind model is that the plasma density inside the magnetosphere can be orders of magnitude larger than in a magnetospheric tail blown back by wind interaction. The occulting disk model also requires an EM wind so that the interaction would be pushed down onto the companion surface, minimizing direct interaction of the wind with the orbiting macroscopic particles

    The purpose of this analysis and model report (AMR) for the Ventilation Model is to analyze the effects of pre-closure continuous ventilation in the Engineered Barrier System (EBS) emplacement drifts and provide heat removal data to support EBS design. It will also provide input data (initial conditions, and time varying boundary conditions) for the EBS post-closure performance assessment and the EBS Water Distribution and Removal Process Model. The objective of the analysis is to develop, describe, and apply calculation methods and models that can be used to predict thermal conditions within emplacement drifts under forced ventilation during the pre-closure period. The scope of this analysis includes: (1) Provide a general description of effects and heat transfer process of emplacement drift ventilation. (2) Develop a modeling approach to simulate the impacts of pre-closure ventilation on the thermal conditions in emplacement drifts. (3) Identify and document inputs to be used for modeling emplacement ventilation. (4) Perform calculations of temperatures and heat removal in the emplacement drift. (5) Address general considerations of the effect of water/moisture removal by ventilation on the repository thermal conditions. The numerical modeling in this document will be limited to heat-only modeling and calculations. Only a preliminary assessment of the heat/moisture ventilation effects and modeling method will be performed in this revision. Modeling of moisture effects on heat removal and emplacement drift temperature may be performed in the future

    This book provides a thorough introduction to the challenge of applying mathematics in real-world scenarios. Modelling tasks rarely involve well-defined categories, and they often require multidisciplinary input from mathematics, physics, computer sciences, or engineering. In keeping with this spirit of modelling, the book includes a wealth of cross-references between the chapters and frequently points to the real-world context. The book combines classical approaches to modelling with novel areas such as soft computing methods, inverse problems, and model uncertainty. Attention is also paid to the interaction between models, data and the use of mathematical software. The reader will find a broad selection of theoretical tools for practicing industrial mathematics, including the analysis of continuum models, probabilistic and discrete phenomena, and asymptotic and sensitivity analysis.

    Full Text Available Currently deep learning has made great breakthroughs in visual and speech processing, mainly because it draws lessons from the hierarchical mode that brain deals with images and speech. In the field of NLP, a topic model is one of the important ways for modeling documents. Topic models are built on a generative model that clearly does not match the way humans write. In this paper, we propose Event Model, which is unsupervised and based on the language processing mechanism of neurolinguistics, to model documents. In Event Model, documents are descriptions of concrete or abstract events seen, heard, or sensed by people and words are objects in the events. Event Model has two stages: word learning and dimensionality reduction. Word learning is to learn semantics of words based on deep learning. Dimensionality reduction is the process that representing a document as a low dimensional vector by a linear mode that is completely different from topic models. Event Model achieves state-of-the-art results on document retrieval tasks.

    The purpose of the Ventilation Model is to simulate the heat transfer processes in and around waste emplacement drifts during periods of forced ventilation. The model evaluates the effects of emplacement drift ventilation on the thermal conditions in the emplacement drifts and surrounding rock mass, and calculates the heat removal by ventilation as a measure of the viability of ventilation to delay the onset of peak repository temperature and reduce its magnitude. The heat removal by ventilation is temporally and spatially dependent, and is expressed as the fraction of heat carried away by the ventilation air compared to the fraction of heat produced by radionuclide decay. One minus the heat removal is called the wall heat fraction, or the remaining amount of heat that is transferred via conduction to the surrounding rock mass. Downstream models, such as the ''Multiscale Thermohydrologic Model'' (BSC 2001), use the wall heat fractions as outputted from the Ventilation Model to initialize their postclosure analyses

    Structural characterization of proteins is essential for understanding life processes at the molecular level. However, only a fraction of known proteins have experimentally determined structures. This fraction is even smaller for protein-protein complexes. Thus, structural modeling of protein-protein interactions (docking) primarily has to rely on modeled structures of the individual proteins, which typically are less accurate than the experimentally determined ones. Such "double" modeling is the Grand Challenge of structural reconstruction of the interactome. Yet it remains so far largely untested in a systematic way. We present a comprehensive validation of template-based and free docking on a set of 165 complexes, where each protein model has six levels of structural accuracy, from 1 to 6 Å C α RMSD. Many template-based docking predictions fall into acceptable quality category, according to the CAPRI criteria, even for highly inaccurate proteins (5-6 Å RMSD), although the number of such models (and, consequently, the docking success rate) drops significantly for models with RMSD > 4 Å. The results show that the existing docking methodologies can be successfully applied to protein models with a broad range of structural accuracy, and the template-based docking is much less sensitive to inaccuracies of protein models than the free docking.

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.

    A development was intended of an alga reef block that is suitable for adherence of algae and difficult of shore-burning by utilizing coal ash. Concretes with different coal ash displacement rates were used to install alga reef blocks embedded with natural rocks, steel plates, and the used desulfurizing agents on three areas (the Usubetsu area, the Tamagawa offing, and Chatsu Bay) including shore-burned sea areas along the coast of Tomari Village. Investigations were made on the states of adherence of useful algae as a result of difference in materials and locations of installation. The best adherence of edible kelp was observed at the Usubetsu area, followed by the Tamagawa offing and Chatsu Bay in that order. Growth conditions of the kelp by locations were conceived of the correlation with how extensively the natural kelp colonies are formed around each location, and how many nutrient salts are present and sea urchins are grown. No remarkable difference was observed in the adherence of algae due to the difference in the coal ash displacement rates. Porous blocks, however, showed less adherence amount. Kelp adherence condition was found good in the order of concrete, natural rocks, and the used desulfurizing agents. No kelps have adhered on the steel plates. 10 refs., 13 figs., 3 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.

The result clarified that generated energy of a detached house reaches 3-4 times as much as consumed one, that of an apartment house is nearly equal to consumed one, and power generation of nearly 380MW is possible based on expected housing supply until 2000. As urban core zone PV community, the survey result on Ebisu Garden Place clarified that the expected PV power supply rate is 10% or more, 20% and 30% or more for hotel and office buildings, high-rise apartment building more than 30 stories, and medium-rise one of 10 and several stories, respectively. In Sakura industrial estate, the maximum generated power was nearly equal to consumed power in a weekday, and as inverse power flow in a holiday was considered, the annual PV power supply rate was extremely high.

    Discussions were given on mass cultivation in a water tank using sea water of an alga Ulvales used as feed for sea urchins and abalone. A fertilizer composed of ammonium sulfate and superphosphate of lime was used, and a water temperature was set as the environmental condition. Two kinds of Ulvales produced in different areas were used. One of the two kinds had full growth periodical and weight increasing rate low, but the other Ulvales had high weight increasing rate and no blights in alga bodies, and was found suitable for mass production. The result of a test on stocks of the latter species may be described as follows: multiple regression formulas for harvest, water temperature and illumination intensity were introduced for each cultivating condition for four cases regarding accommodation density and harvest frequency; and if a cultivating condition by which the harvest is maximized is adopted, a one cubic meter water tank placed on a place with good sunlight may be expected of producing as much harvest as 2181 grams at water temperature of 15{degree}C and 4899 grams at 25{degree}C. The cultivation requires the following precautions: aeration is required; sea water should be introduced into the tank; a mixed fertilizer with ratio of ammonium sulfate at 100 to superphosphate of lime at 15 may be used; water temperatures suitable for mass cultivation are 13 to 15{degree}C or higher; and light must be irradiated evenly. 14 refs., 9 figs., 5 tabs.

    Twenty six years have passed since the first geothermal power station was constructed in Matsuo-mura of Iwate Prefecture, Japan. This paper describes the history, the present situation and the future conception of the geothermal energy utilization in this village. This village includes Hachimantai of a vantage ground in the center and has the gross area of 233.8km[sup 2], the annual average temperature of 8.3 centigrade and the continuous snow cover period of about 100 days. The hot water leading facility was cooperatively constructed by Japan Metals and Chemicals, Hachimantai Hot Spring Development and Matsuo-mura. The total working expense is 539.3 million yen. Hot water sources are the condensate from the condenser of geothermal power plant and hot spring. This mixed hot water of 4.3 t/min is led to respective facilities. The hot water supplying channel has the length of 12.8km from the power station through the Hachimantai hot spring resort, Kamiyogi to Takaishino. Respective total areas of greenhouses using hydrothermal fluid in both districts are 1,075ha and the inlet temperature of hot water is 60 centigrade and kinds of crop are 5 like green pepper and others. Takaishino agricultural park has selected flower and ornamental plant culture such as poppy anemone, stock and statice which are suitable for this district of low temperature and insufficient sunshine. The planted area is 10,700m[sup 2]. 2 refs., 9 figs., 4 tabs.

    Recent progress in understanding the observed properties of type I supernovae as a consequence of the thermonuclear detonation of white dwarf stars and the ensuing decay of the Ni-56 produced therein is reviewed. The expected nucleosynthesis and gamma-line spectra for this model of type I explosions and a model for type II explosions are presented. Finally, a qualitatively new approach to the problem of massive star death and type II supernovae based upon a combination of rotation and thermonuclear burning is discussed. While the theoretical results of existing models are predicated upon the assumption of a successful core bounce calculation and the neglect of such two-dimensional effects as rotation and magnetic fields the new model suggests an entirely different scenario in which a considerable portion of the energy carried by an equatorially ejected blob is deposited in the red giant envelope overlying the mantle of the star

    Like any other type of uncertainty, model uncertainty should be treated in terms of probabilities. The question is how to do this. The most commonly-used approach has a drawback related to the interpretation of the probabilities assigned to the models. If we step back and look at the big picture, asking what the appropriate focus of the model uncertainty question should be in the context of risk and decision analysis, we see that a different probabilistic approach makes more sense, although it raise some implementation questions. Current work that is underway to address these questions looks very promising

    Windmills are one of the oldest prime movers and have been used for more than 700 years in Europe. The transition from low speed windmills for grain grinding and water pumping to high speed wind turbines for electric power generation had occurred at the end of 19{sup th} century. This paper, at first, reviews the windmill technologies and the researchers before 20th century. Then describes the back ground of how the wind power generator has existed and how the four pioneers developed their wind power generator. The historical developments of windmills to wind turbines in this century are studied focusing mainly on Danish activities. Then, the effort of the development of large wind turbine such as Smith-Putnum's first MW machine in U.S.A. and other mammoth machine concept are introduced. The new concept machines such as Savonius and Darrieus wind turbines in 1920s to 1930s are also explained. Finally, the novel technologies of wind turbine covering larger machines, variable speed generators, special wing sections for wind turbines, theoretical analysis method of wind turbine performance, offshore wind turbines, and wind turbine control technologies are stated.

    Processing of a large amount of coal ash is a serious problem in considering the locational conditions of coal firing power generation plants. 46% of the coal ash was effectively used in 1985, and the remaining 54% was disposed at landfills on land and sea. Positive promotion of the effective use of coal ash is the necessity. A production method for an artificial lightweight aggregate utilizing coal ash was established by a joint research. The history of the research and development of this artificial lightweight aggregate (brand name: FA-lIGHT), outline of the manufacturing facilities, physical properties and result of use are introduced. The lightweight aggregates are used not only for the construction of multistoried buildings but also used as most suitable aggregates for making lightweight large scale panels and concrete secondary products such as lightweight blocks. FA-LIGHT is most suitable for use in the production of concrete lightweight aggregates, and can be used for hydroponic agriculture and for the improvement of drainage of land. Spread of its use is expected. 5 figs., 5 tabs.

    The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

    Several kinds of silica gel modified by alkoxyalcohols were synthesized by refluxing and dehyration and the organic reactions were studied when these silica gels were used as the catalyst. It could be confirmed by FT-IR spectra, DTA and elementary analysis that alkoxylalcohols adhere to the surface of silica gels without any decomposition. The acetate was produced by using alkyl halides. It was found that the modified silica gels had clearly the catalytic action for the reaction with n-hexyl bromide and dibromoethane although unmodified silica gels did not show the catalytic action. The reducing reaction of carbonyl compounds was carried out. The reaction proceeded at 25 centigrade for acetophenone, cyclohexanone, 1-indanone and 2-octanone to produce the corresponding reduction products. 11 refs., 5 figs., 4 tabs.

    The coal cartridge system (CCS) is a series of the total system, in which coal is processed centrally at a supply base for each unit of consumer areas, supplied as pulverized coal in bulk units, and coal ash after combustion is recovered and treated. The system is expected of advantages resulted from the centralized production, elimination of handling troubles, and cleanliness. Following a small scale demonstration test, a large demonstration test for practically usable scale has begun in 1990, and completed in fiscal 1995. This paper introduces the CCS and reports the result of the test. In the large demonstration test, a supply station (with manufacturing capability of 200,000 tons a year) was installed in the Aichi refinery of Idemitsu Kosan Co., Ltd., and systematization on quality design and system technologies has been carried out. Long-term continuous operation for five years was achieved (operation time of the supply facilities was about 19,000 hours) without a failure and accident, to which every elemental technology was evaluated highly, and convenience and reliability of the system was verified. 13 figs., 3 tabs.

    An overview is given on the development situation of a Zn-Br battery as a power storage system. The system is aimed at storing excess power at night and supplying the on-load demand during daytime. The power storage technology requires a large output and capacity of MWh level, long term stability and durability, and cost as low as pumped storage power generation. Four kinds of batteries have been examined to cope with the conditions, in which development of Zn-Br batteries along with Na-S batteries is in progress towards practicability. As a power conversion method for this system, GTO has been employed for a large capacity unit and IGBT for a medium/small capacity unit. The reliability of the Zn-Br batteries against leakage was improved by laminating each cell by hot plate welding. The service life was improved by using a material with a high bromine resistance in place of the conventional electrode constituent material. Although the battery efficiency was influenced by each resistance of electrode, film and electrolytic solution, distance between electrodes, temperature, etc., these correlations were clarified so as to establish the simulation technology. At present, the system realizes 50kW and 40kWh/m{sup 3}. 1 ref., 8 figs.

    Solvothermal reaction is reaction under high temperature and high pressure, which is expected to fabricate new functional materials. In this study, the materials are classified into two fields, i.e., inorganic materials, metals and their composites and organic materials and their composites. The current status of R and D of production and processing technology in each field is surveyed and the prospect of it is discussed. For the inorganic materials, metals and their composites, it is explained that very fine metal oxide particles, complex oxides, single crystals, whiskers, compounds with layer structure, metastable compounds, ion conductors and catalysts with high ability could be produced only by controlling the solvothermal reactions in atomic order. For the organic materials and their composites, surveyed results of the solvothermal technique using non-aqueous solutions are mainly provided. The necessity of a national project for researches on the solvothermal reactions is proposed from the viewpoint of resource, environment and energy. 777 refs., 38 figs., 26 tabs.

    Entrails of fish, fowls and domestic animals are mostly incinerated at large expenses, although partly used as foods. This study is to test `possibility of vegetable cultivation with fish breeding water,` where the entrail wastes are used as baits for fish breeding, and fish excretions are used as the fertilizer for vegetable cultivation to purify water for fish breeding. The cultivation bed consists of two sections, one for fish breeding/vegetable cultivation and the other for vegetable cultivation by the normal method. Vegetable grow notably less in the former than in the latter, 54.6 to 79.5 versus 100. Spinach contains slightly higher contents of vitamins A and C by 6 and 13%, when cultivated in the former than in the latter. Quantities of total nitrogen, phosphorus and potassium as the fertilizer components in the former are 49, 49 and 1.7% of those in the latter. It is predicted, judging from growth of the vegetables, that the former gives a harvest comparable with that by the latter, when given a 6 to 13 days longer cultivation period. 3 figs., 2 tabs.

    Although a part of the entrails of fishes, birds and livestock is used for food, most of them are treated by costly combustion because of their bad odor and looking, and International Environment and Welfare Laboratory, Toyama prefecture in Japan is studying their profitable treatment. As a part of such study, possibility of hydroponic cultivation of vegetable was tested using fish breeding water including excretions of fishes and residual feeds after use of waste as feed, and the growth condition, safety and effectiveness of cultured vegetable were verified. Three-hundred and fifty viviparous Oryzias were released into a breeding water area with no controlled pH and EC (electric conductivity). For comparison a culture solution area of 6.0 in pH and 1.2ms/cm in EC was prepared. The result on cultivation of 6 kinds of vegetable in culture beds supported by circulation of these water showed that hydroponic cultivation of vegetable using fish breeding water is possible, and average growth of 68% is obtained although difference in growth for every vegetable is found. 8 figs., 5 tabs.

    The temperature measurements provided by thermocouples (TCs) are important for the operation of pressurized water reactors. During severe inadequate core cooling incidents, extreme temperatures may cause type K thermocouples (TCs) used for core exit temperature monitoring to perform poorly. A model of TC electrical behavior has been developed to determine how TCs react under extreme temperatures. The model predicts the voltage output of the TC and its impedance. A series of experiments were conducted on a length of type K thermocouple to validate the model. Impedance was measured at several temperatures between 22 0 C and 1100 0 C and at frequencies between dc and 10 MHz. The model was able to accurately predict impedance over this wide range of conditions. The average percentage difference between experimental data and the model was less than 6.5%. Experimental accuracy was +-2.5%. There is a sriking difference between impedance versus frequency plots at 300 0 C and at higher temperatures. This may be useful in validating TC data during accident conditions

    Warm absorber spectra are characterized by the many lines from partially ionized intermediate-Z elements, and iron, detected with the grating instruments on Chandra and XMM-Newton. If these ions are formed in a gas which is in photoionization equilibrium, they correspond to a broad range of ionization parameters, although there is evidence for certain preferred values. A test for any dynamical model for these outflows is to reproduce these properties, at some level of detail. In this paper we present a statistical analysis of the ionization distribution which can be applied both the observed spectra and to theoretical models. As an example, we apply it to our dynamical models for warm absorber outflows, based on evaporation from the molecular torus.

    A classical description of the one dimensional radiative transfer treatment of vegetation canopies was completed and the results were tested against measured prairie (blue grama) and agricultural canopies (soybean). Phase functions are calculated in terms of directly measurable biophysical characteristics of the canopy medium. While the phase functions tend to exhibit backscattering anisotropy, their exact behavior is somewhat more complex and wavelength dependent. A Monte Carlo model was developed that treats soil surfaces with large periodic variations in three dimensions. A photon-ray tracing technology is used. Currently, the rough soil surface is described by analytic functions and appropriate geometric calculations performed. A bidirectional reflectance distribution function is calculated and, hence, available for other atmospheric or canopy reflectance models as a lower boundary condition. This technique is used together with an adding model to calculate several cases where Lambertian leaves possessing anisotropic leaf angle distributions yield non-Lambertian reflectance; similar behavior is exhibited for simulated soil surfaces.

    Mathematical models are the decisive tool to explain and predict phenomena in the natural and engineering sciences. With this book readers will learn to derive mathematical models which help to understand real world phenomena. At the same time a wealth of important examples for the abstract concepts treated in the curriculum of mathematics degrees are given. An essential feature of this book is that mathematical structures are used as an ordering principle and not the fields of application. Methods from linear algebra, analysis and the theory of ordinary and partial differential equations are thoroughly introduced and applied in the modeling process. Examples of applications in the fields electrical networks, chemical reaction dynamics, population dynamics, fluid dynamics, elasticity theory and crystal growth are treated comprehensively.

    Recent progress in understanding the observed properties of Type I supernovae as a consequence of the thermonuclear detonation of white dwarf stars and the ensuing decay of the 56 Ni produced therein is reviewed. Within the context of this model for Type I explosions and the 1978 model for Type II explosions, the expected nucleosynthesis and gamma-line spectra from both kinds of supernovae are presented. Finally, a qualitatively new approach to the problem of massive star death and Type II supernovae based upon a combination of rotation and thermonuclear burning is discussed

    This paper describes the achievements of the discussions in fiscal 1998 on the utilization facilities related to the coal bed methane gas supply plan for the city of Tieling in China. The gas quality standard calls for 3,500 kcal/m{sup 3} or more (methane concentration of 41% or higher). The supply is planned to start in December 1999, and continue the supply of 141,000 Nm{sup 3}/day in 2000, and 212,000 Nm{sup 3}/day in 2001 and thereafter. A gas supply center to collect gases recovered from each mine will be installed in the vicinity of the existing gas holder located about 2 km east of the Tiefa Mining Bureau. The Japanese side bears the cost of installing a gas compression and transportation facility for gas supply to the city of Tieling, a monitoring system, and devices for comprehensive surveillance system. This paper shows the overall plan drawings, the drain separator room building plan, the plans for arranging devices in the machine room, and the piping scheme. In addition, the piping plan around the gas holder, and the basic device plan are shown. Also appearing in the paper are the machine summary drawings, summarized flow charts, gas holder plan, de-humidifier plan, and electricity and instrumentation plans. The main body and supporting structure for the gas holder, and the foundation strength calculation sheets are also shown. Descriptions are given also on the facilities to deal with variation in demand quantity and supply quantity. (NEDO)

    The emergence of interactive art has blurred the line between electronic, computer graphics and art. Here we apply this art form to numerical models. Here we show how the transformation of a numerical model into an interactive painting can both provide insights and solve real world problems. The cases that are used as an example include forensic reconstructions, dredging optimization, barrier design. The system can be fed using any source of time varying vector fields, such as hydrodynamic models. The cases used here, the Indian Ocean (HYCOM), the Wadden Sea (Delft3D Curvilinear), San Francisco Bay (3Di subgrid and Delft3D Flexible Mesh), show that the method used is suitable for different time and spatial scales. High resolution numerical models become interactive paintings by exchanging their velocity fields with a high resolution (>=1M cells) image based flow visualization that runs in a html5 compatible web browser. The image based flow visualization combines three images into a new image: the current image, a drawing, and a uv + mask field. The advection scheme that computes the resultant image is executed in the graphics card using WebGL, allowing for 1M grid cells at 60Hz performance on mediocre graphic cards. The software is provided as open source software. By using different sources for a drawing one can gain insight into several aspects of the velocity fields. These aspects include not only the commonly represented magnitude and direction, but also divergence, topology and turbulence .

    This paper addresses the question of, if one overlooks their idiosyncratic difficulties, what could be learned from the various models about the pulsar wind? The wind model requires an MHD wind from the pulsar, namely, one with enough particles that the Poynting flux of the wind can be thermalized. Otherwise, there is no shock and the pulsar wind simply reflects like a flashlight beam. Additionally, a large flux of energetic radiation from the pulsar is required to accompany the wind and drive the wind off the companion. The magnetosphere model probably requires an EM wind, which is Poynting flux dominated. Reflection in this case would arguably minimize the intimate interaction between the two flows that leads to tail formation and thereby permit a weakly magnetized tail. The occulting disk model also would point to an EM wind so that the interaction would be pushed down onto the companion surface (to form the neutral fountain) and so as to also minimize direct interaction of the wind with the orbiting macroscopic particles

    The BIOTRAN model was developed at Los Alamos to help predict short- and long-term consequences to man from releases of radionuclides into the environment. It is a dynamic model that simulates on a daily and yearly basis the flux of biomass, water, and radionuclides through terrestrial and aquatic ecosystems. Biomass, water, and radionuclides are driven within the ecosystems by climate variables stochastically generated by BIOTRAN each simulation day. The climate variables influence soil hydraulics, plant growth, evapotranspiration, and particle suspension and deposition. BIOTRAN has 22 different plant growth strategies for simulating various grasses, shrubs, trees, and crops. Ruminants and humans are also dynamically simulated by using the simulated crops and forage as intake for user-specified diets. BIOTRAN has been used at Los Alamos for long-term prediction of health effects to populations following potential accidental releases of uranium and plutonium. Newly developed subroutines are described: a human dynamic physiological and metabolic model; a soil hydrology and irrigation model; limnetic nutrient and radionuclide cycling in fresh-water lakes. 7 references

    The ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2003) presents the methodology for evaluating potential criticality situations in the monitored geologic repository. As stated in the referenced Topical Report, the detailed methodology for performing the disposal criticality analyses will be documented in model reports. Many of the models developed in support of the Topical Report differ from the definition of models as given in the Office of Civilian Radioactive Waste Management procedure AP-SIII.10Q, ''Models'', in that they are procedural, rather than mathematical. These model reports document the detailed methodology necessary to implement the approach presented in the Disposal Criticality Analysis Methodology Topical Report and provide calculations utilizing the methodology. Thus, the governing procedure for this type of report is AP-3.12Q, ''Design Calculations and Analyses''. The ''Criticality Model'' is of this latter type, providing a process evaluating the criticality potential of in-package and external configurations. The purpose of this analysis is to layout the process for calculating the criticality potential for various in-package and external configurations and to calculate lower-bound tolerance limit (LBTL) values and determine range of applicability (ROA) parameters. The LBTL calculations and the ROA determinations are performed using selected benchmark experiments that are applicable to various waste forms and various in-package and external configurations. The waste forms considered in this calculation are pressurized water reactor (PWR), boiling water reactor (BWR), Fast Flux Test Facility (FFTF), Training Research Isotope General Atomic (TRIGA), Enrico Fermi, Shippingport pressurized water reactor, Shippingport light water breeder reactor (LWBR), N-Reactor, Melt and Dilute, and Fort Saint Vrain Reactor spent nuclear fuel (SNF). The scope of this analysis is to document the criticality computational method. The criticality

    Acyclic models is a method heavily used to analyze and compare various homology and cohomology theories appearing in topology and algebra. This book is the first attempt to put together in a concise form this important technique and to include all the necessary background. It presents a brief introduction to category theory and homological algebra. The author then gives the background of the theory of differential modules and chain complexes over an abelian category to state the main acyclic models theorem, generalizing and systemizing the earlier material. This is then applied to various cohomology theories in algebra and topology. The volume could be used as a text for a course that combines homological algebra and algebraic topology. Required background includes a standard course in abstract algebra and some knowledge of topology. The volume contains many exercises. It is also suitable as a reference work for researchers.

Estimated emissions from the operation of a hypothetical 500 MW coal-fired power plant are given. Ozone is considered a secondary pollutant, since it is not emitted directly into the atmosphere but is formed from other air pollutants, specifically, nitrogen oxides (NO), and non-methane organic compounds (NMOQ) in the presence of sunlight. (NMOC are sometimes referred to as hydrocarbons, HC, or volatile organic compounds, VOC, and they may or may not include methane). Additionally, ozone formation Alternative is a function of the ratio of NMOC concentrations to NO{sub x} concentrations. A typical ozone isopleth is shown, generated with the Empirical Kinetic Modeling Approach (EKMA) option of the Environmental Protection Agency's (EPA) Ozone Isopleth Plotting Mechanism (OZIPM-4) model. Ozone isopleth diagrams, originally generated with smog chamber data, are more commonly generated with photochemical reaction mechanisms and tested against smog chamber data. The shape of the isopleth curves is a function of the region (i.e. background conditions) where ozone concentrations are simulated. The location of an ozone concentration on the isopleth diagram is defined by the ratio of NMOC and NO{sub x} coordinates of the point, known as the NMOC/NO{sub x} ratio. Results obtained by the described model are presented.

    As clinical studies reveal that chemotherapeutic agents may impair several different cognitive domains in humans, the development of preclinical animal models is critical to assess the degree of chemotherapy-induced learning and memory deficits and to understand the underlying neural mechanisms. In this chapter, the effects of various cancer chemotherapeutic agents in rodents on sensory processing, conditioned taste aversion, conditioned emotional response, passive avoidance, spatial learning, cued memory, discrimination learning, delayed-matching-to-sample, novel-object recognition, electrophysiological recordings and autoshaping is reviewed. It appears at first glance that the effects of the cancer chemotherapy agents in these many different models are inconsistent. However, a literature is emerging that reveals subtle or unique changes in sensory processing, acquisition, consolidation and retrieval that are dose- and time-dependent. As more studies examine cancer chemotherapeutic agents alone and in combination during repeated treatment regimens, the animal models will become more predictive tools for the assessment of these impairments and the underlying neural mechanisms. The eventual goal is to collect enough data to enable physicians to make informed choices about therapeutic regimens for their patients and discover new avenues of alternative or complementary therapies that reduce or eliminate chemotherapy-induced cognitive deficits.

    Understanding the properties and behavior of biomembranes is fundamental to many biological processes and technologies. Microdomains in biomembranes or ''lipid rafts'' are now known to be an integral part of cell signaling, vesicle formation, fusion processes, protein trafficking, and viral and toxin infection processes. Understanding how microdomains form, how they depend on membrane constituents, and how they act not only has biological implications, but also will impact Sandia's effort in development of membranes that structurally adapt to their environment in a controlled manner. To provide such understanding, we created physically-based models of biomembranes. Molecular dynamics (MD) simulations and classical density functional theory (DFT) calculations using these models were applied to phenomena such as microdomain formation, membrane fusion, pattern formation, and protein insertion. Because lipid dynamics and self-organization in membranes occur on length and time scales beyond atomistic MD, we used coarse-grained models of double tail lipid molecules that spontaneously self-assemble into bilayers. DFT provided equilibrium information on membrane structure. Experimental work was performed to further help elucidate the fundamental membrane organization principles.

    In this study, we investigated the relationship of indicated mean effective pressure (IMEP) for a spark ignition engine under lean combustion with the cyclic variation of mass fraction burned by measuring the energy release from the spark plug, intensity of the light emission from the flame and the cylinder pressure at the same time. In order to minimized an error in the initial and late combustion sages of the mass fraction burned to be obtained by cylinder pressure, spark plug energy and intensity of light emission were measured. As a result, it was found that there are three main causes of cyclic variation of IMEP. These consist of the burning speed during the initial stage of combustion, variation in the total mass fraction burned, and variation of the late burning during the late expansion stroke. Thus, we determined that there is a favorable interrelationship between the IMEPs and the corrected mass fraction burned. 13 refs., 9 figs., 1 tab.

    In the constant-current/constant-voltage charging method that has been in application for EV (electric vehicle) lead-acid batteries, power load is generated only at the initial part of the charging process, and therefore the method cannot be said to be sufficiently contributory to the levelling of power loads. In this report, a proposed 2-step constant-current charging method is assessed for applicability, and another charging method is introduced, which extends battery life and utilizes low-cost night-time power more effectively. It is found that the proposed 2-step constant-current charging method (1st step: 12A, 2nd step: 3A) completes the charging process in eight hours, that it assumes a charging pattern more suitable for contributing to the effective use of night-time power than the conventional method, and that it extends the battery life of approximately 170 cycles to approximately 300 cycles. In a study seeking for a charging method capable of utilizing night-time power more efficiently, the 1st-step current of 12A is increased to 30A for shortening the charging time, and then it is found that this change extends the battery cycle life and improves on charging efficiency. The conclusion is that possibilities are high that an increase in the 1st-step current prolongs the battery life cycle and shortens the charting time. 16 refs., 28 figs., 8 tabs.

    Full Text Available Distance predicting functions may be used in a variety of applications for estimating travel distances between points. To evaluate the accuracy of a distance predicting function and to determine its parameters, a goodness-of-fit criteria is employed. AD (Absolute Deviations, SD (Squared Deviations and NAD (Normalized Absolute Deviations are the three criteria that are mostly employed in practice. In the literature some assumptions have been made about the properties of each criterion. In this paper, we present statistical analyses performed to compare the three criteria from different perspectives. For this purpose, we employ the ℓkpθ-norm as the distance predicting function, and statistically compare the three criteria by using normalized absolute prediction error distributions in seventeen geographical regions. We find that there exist no significant differences between the criteria. However, since the criterion SD has desirable properties in terms of distance modelling procedures, we suggest its use in practice.

The main goal of this study is to differentiate the Binominal model and the Black Scholes model by using two statistical model - t-test and Tukey model at one period. Finally, the result showed that there is no significant difference between the means of the European options by using the above two models.

    2017-05-23

    We consider the relation between SYK-like models and vector models by studying a toy model where a tensor field is coupled with a vector field. By integrating out the tensor field, the toy model reduces to the Gross-Neveu model in 1 dimension. On the other hand, a certain perturbation can be turned on and the toy model flows to an SYK-like model at low energy. A chaotic-nonchaotic phase transition occurs as the sign of the perturbation is altered. We further study similar models that possess chaos and enhanced reparameterization symmetries.

    A review is made of some properties of the rotating Universe models. Godel's model is identified as a generalized filted model. Some properties of new solutions of the Einstein's equations, which are rotating non-stationary Universe models, are presented and analyzed. These models have the Godel's model as a particular case. Non-stationary cosmological models are found which are a generalization of the Godel's metrics in an analogous way in which Friedmann is to the Einstein's model. (L.C.) [pt

    This chapter shows the usefulness of terminological concept modeling as a first step in data modeling. First, we introduce terminological concept modeling with terminological ontologies, i.e. concept systems enriched with characteristics modeled as feature specifications. This enables a formal...... account of the inheritance of characteristics and allows us to introduce a number of principles and constraints which render concept modeling more coherent than earlier approaches. Second, we explain how terminological ontologies can be used as the basis for developing conceptual and logical data models....... We also show how to map from the various elements in the terminological ontology to elements in the data models, and explain the differences between the models. Finally the usefulness of terminological ontologies as a prerequisite for IT development and data modeling is illustrated with examples from...

  14. Model-to-model interface for multiscale materials modeling

    Energy Technology Data Exchange (ETDEWEB)

    Antonelli, Perry Edward [Iowa State Univ., Ames, IA (United States)

    2017-12-17

    A low-level model-to-model interface is presented that will enable independent models to be linked into an integrated system of models. The interface is based on a standard set of functions that contain appropriate export and import schemas that enable models to be linked with no changes to the models themselves. These ideas are presented in the context of a specific multiscale material problem that couples atomistic-based molecular dynamics calculations to continuum calculations of fluid ow. These simulations will be used to examine the influence of interactions of the fluid with an adjacent solid on the fluid ow. The interface will also be examined by adding it to an already existing modeling code, Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) and comparing it with our own molecular dynamics code.

    If we are to discuss and consider cognitive models, we must first come to grips with two questions: (1) What is cognition; (2) What is a model. Presumably, the answers to these questions can provide a basis for defining a cognitive model. Accordingly, this paper first places these two questions into perspective. Then, cognitive models are set within the context of computer simulation models and a number of computer simulations of cognitive processes are described. Finally, pervasive issues are discussed vis-a-vis cognitive modeling in the computer simulation context

    In this paper we construct topological sigma models which include a potential and are related to twisted massive supersymmetric sigma models. Contrary to a previous construction these models have no central charge and do not require the manifold to admit a Killing vector. We use the topological massive sigma model constructed here to simplify the calculation of the observables. Lastly it is noted that this model can be viewed as interpolating between topological massless sigma models and topological Landau-Ginzburg models. ((orig.))

    Science.gov (United States)

    Hasegawa, Tomoka; Amizuka, Norio

    Modeling, adapting structures to loading by changing bone size and shapes, often takes place in bone of the fetal and developmental stages, while bone remodeling-replacement of old bone into new bone-is predominant in the adult stage. Modeling can be divided into macro-modeling(macroscopic modeling)and mini-modeling(microscopic modeling). In the cellular process of mini-modeling, unlike bone remodeling, bone lining cells, i.e., resting flattened osteoblasts covering bone surfaces will become active form of osteoblasts, and then, deposit new bone onto the old bone without mediating osteoclastic bone resorption. Among the drugs for osteoporotic treatment, eldecalcitol(a vitamin D3 analog)and teriparatide(human PTH[1-34])could show mini-modeling based bone formation. Histologically, mature, active form of osteoblasts are localized on the new bone induced by mini-modeling, however, only a few cell layer of preosteoblasts are formed over the newly-formed bone, and accordingly, few osteoclasts are present in the region of mini-modeling. In this review, histological characteristics of bone remodeling and modeling including mini-modeling will be introduced.

    2003-01-01

    To support national environmental policy, it is desirable to forecast and analyse environmental indicators consistently with economic variables. However, environmental indicators are physical measures linked to physical activities that are not specified in economic models. One way to deal with this is to develop environmental satellite models linked to economic models. The system of models presented gives a frame of reference where emissions of greenhouse gases, acid gases, and leaching of nutrients to the aquatic environment are analysed in line with - and consistently with - macroeconomic variables. This paper gives an overview of the data and the satellite models. Finally, the results of applying the model system to calculate the impacts on emissions and the economy are reviewed in a few illustrative examples. The models have been developed for Denmark; however, most of the environmental data used are from the CORINAIR system implemented in numerous countries

    The purpose of this report is to document the Geologic Framework Model (GFM), Version 3.1 (GFM3.1) with regard to data input, modeling methods, assumptions, uncertainties, limitations, and validation of the model results, qualification status of the model, and the differences between Version 3.1 and previous versions. The GFM represents a three-dimensional interpretation of the stratigraphy and structural features of the location of the potential Yucca Mountain radioactive waste repository. The GFM encompasses an area of 65 square miles (170 square kilometers) and a volume of 185 cubic miles (771 cubic kilometers). The boundaries of the GFM were chosen to encompass the most widely distributed set of exploratory boreholes (the Water Table or WT series) and to provide a geologic framework over the area of interest for hydrologic flow and radionuclide transport modeling through the unsaturated zone (UZ). The depth of the model is constrained by the inferred depth of the Tertiary-Paleozoic unconformity. The GFM was constructed from geologic map and borehole data. Additional information from measured stratigraphy sections, gravity profiles, and seismic profiles was also considered. This interim change notice (ICN) was prepared in accordance with the Technical Work Plan for the Integrated Site Model Process Model Report Revision 01 (CRWMS M&O 2000). The constraints, caveats, and limitations associated with this model are discussed in the appropriate text sections that follow. The GFM is one component of the Integrated Site Model (ISM) (Figure l), which has been developed to provide a consistent volumetric portrayal of the rock layers, rock properties, and mineralogy of the Yucca Mountain site.

There exist two different classes of models without singularities: (i) ever-expanding models, (ii) oscillating models. The first class contains models with hot big bang. For these models there exist at the beginning of the universe-in contrast to Einstein's theory-very high but finite densities of matter and radiation with a big bang of very short duration. After short time these models pass into the homogeneous and isotropic models of Einstein's theory with spatial curvature equal to zero and cosmological constant ALPHA >= O. (author)

    2000-01-01

    The Integrated Site Model (ISM) provides a framework for discussing the geologic features and properties of Yucca Mountain, which is being evaluated as a potential site for a geologic repository for the disposal of nuclear waste. The ISM is important to the evaluation of the site because it provides 3-D portrayals of site geologic, rock property, and mineralogic characteristics and their spatial variabilities. The ISM is not a single discrete model; rather, it is a set of static representations that provide three-dimensional (3-D), computer representations of site geology, selected hydrologic and rock properties, and mineralogic-characteristics data. These representations are manifested in three separate model components of the ISM: the Geologic Framework Model (GFM), the Rock Properties Model (RPM), and the Mineralogic Model (MM). The GFM provides a representation of the 3-D stratigraphy and geologic structure. Based on the framework provided by the GFM, the RPM and MM provide spatial simulations of the rock and hydrologic properties, and mineralogy, respectively. Functional summaries of the component models and their respective output are provided in Section 1.4. Each of the component models of the ISM considers different specific aspects of the site geologic setting. Each model was developed using unique methodologies and inputs, and the determination of the modeled units for each of the components is dependent on the requirements of that component. Therefore, while the ISM represents the integration of the rock properties and mineralogy into a geologic framework, the discussion of ISM construction and results is most appropriately presented in terms of the three separate components. This Process Model Report (PMR) summarizes the individual component models of the ISM (the GFM, RPM, and MM) and describes how the three components are constructed and combined to form the ISM

    Full Text Available An intensive research from academics and practitioners has been provided regarding models for bankruptcy prediction and credit risk management. In spite of numerous researches focusing on forecasting bankruptcy using traditional statistics techniques (e.g. discriminant analysis and logistic regression and early artificial intelligence models (e.g. artificial neural networks, there is a trend for transition to machine learning models (support vector machines, bagging, boosting, and random forest to predict bankruptcy one year prior to the event. Comparing the performance of this with unconventional approach with results obtained by discriminant analysis, logistic regression, and neural networks application, it has been found that bagging, boosting, and random forest models outperform the others techniques, and that all prediction accuracy in the testing sample improves when the additional variables are included. On the other side the prediction accuracy of old and well known bankruptcy prediction models is quiet high. Therefore, we aim to analyse these in some way old models on the dataset of Slovak companies to validate their prediction ability in specific conditions. Furthermore, these models will be modelled according to new trends by calculating the influence of elimination of selected variables on the overall prediction ability of these models.

There are many examples of hydrological and sediment connectivity on a watershed scale; in consequence, a process-based understanding of connectivity is crucial to help managers understand their systems and adopt adequate measures for flood prevention, pollution mitigation and soil protection, among others. Modelling is often used as a tool to understand and predict fluxes within a catchment by complementing observations with model results. Catchment models should therefore be able to reproduce the linkages, and thus the connectivity of water and sediment fluxes within the systems under simulation. In modelling, a high level of spatial and temporal detail is desirable to ensure taking into account a maximum number of components, which then enables connectivity to emerge from the simulated structures and functions. However, computational constraints and, in many cases, lack of data prevent the representation of all relevant processes and spatial/temporal variability in most models. In most cases, therefore, the level of detail selected for modelling is too coarse to represent the system in a way in which connectivity can emerge; a problem which can be circumvented by representing fine-scale structures and processes within coarser scale models using a variety of approaches. This poster focuses on the results of ongoing discussions on modelling connectivity held during several workshops within COST Action Connecteur. It assesses the current state of the art of incorporating the concept of connectivity in hydrological and sediment models, as well as the attitudes of modellers towards this issue. The discussion will focus on the different approaches through which connectivity

  20. Efficient polarimetric BRDF model.

    Science.gov (United States)

    Renhorn, Ingmar G E; Hallberg, Tomas; Boreman, Glenn D

    2015-11-30

    The purpose of the present manuscript is to present a polarimetric bidirectional reflectance distribution function (BRDF) model suitable for hyperspectral and polarimetric signature modelling. The model is based on a further development of a previously published four-parameter model that has been generalized in order to account for different types of surface structures (generalized Gaussian distribution). A generalization of the Lambertian diffuse model is presented. The pBRDF-functions are normalized using numerical integration. Using directional-hemispherical reflectance (DHR) measurements, three of the four basic parameters can be determined for any wavelength. This simplifies considerably the development of multispectral polarimetric BRDF applications. The scattering parameter has to be determined from at least one BRDF measurement. The model deals with linear polarized radiation; and in similarity with e.g. the facet model depolarization is not included. The model is very general and can inherently model extreme surfaces such as mirrors and Lambertian surfaces. The complex mixture of sources is described by the sum of two basic models, a generalized Gaussian/Fresnel model and a generalized Lambertian model. Although the physics inspired model has some ad hoc features, the predictive power of the model is impressive over a wide range of angles and scattering magnitudes. The model has been applied successfully to painted surfaces, both dull and glossy and also on metallic bead blasted surfaces. The simple and efficient model should be attractive for polarimetric simulations and polarimetric remote sensing.

    The Hanford Environmental Dose Reconstruction (HEDR) Project has developed a set of computer models for estimating the possible radiation doses that individuals may have received from past Hanford Site operations. This document describes the validation of these models. In the HEDR Project, the model validation exercise consisted of comparing computational model estimates with limited historical field measurements and experimental measurements that are independent of those used to develop the models. The results of any one test do not mean that a model is valid. Rather, the collection of tests together provide a level of confidence that the HEDR models are valid

    Composite models of hadrons are considered. The main attention is paid to the Sakata, S model. In the framework of the model it is presupposed that proton, neutron and Λ particle are the fundamental particles. Theoretical studies of unknown fundamental constituents of a substance have led to the creation of the quark model. In the framework of the quark model using the theory of SU(6)-symmetry the classification of mesons and baryons is considered. Using the quark model relations between hadron masses, their spins and electromagnetic properties are explained. The problem of three-colour model with many flavours is briefly presented

    2017-01-01

    Equivalences of two classes of dynamic models for weakly stationary multivariate time series are discussed: dynamic factor models and autoregressive models. It is shown that exploratory dynamic factor models can be rotated, yielding an infinite set of equivalent solutions for any observed series. It also is shown that dynamic factor models with lagged factor loadings are not equivalent to the currently popular state-space models, and that restriction of attention to the latter type of models may yield invalid results. The known equivalent vector autoregressive model types, standard and structural, are given a new interpretation in which they are conceived of as the extremes of an innovating type of hybrid vector autoregressive models. It is shown that consideration of hybrid models solves many problems, in particular with Granger causality testing.

  14. Geochemistry Model Validation Report: External Accumulation Model

    International Nuclear Information System (INIS)

    Zarrabi, K.

    2001-01-01

    The purpose of this Analysis and Modeling Report (AMR) is to validate the External Accumulation Model that predicts accumulation of fissile materials in fractures and lithophysae in the rock beneath a degrading waste package (WP) in the potential monitored geologic repository at Yucca Mountain. (Lithophysae are voids in the rock having concentric shells of finely crystalline alkali feldspar, quartz, and other materials that were formed due to entrapped gas that later escaped, DOE 1998, p. A-25.) The intended use of this model is to estimate the quantities of external accumulation of fissile material for use in external criticality risk assessments for different types of degrading WPs: U.S. Department of Energy (DOE) Spent Nuclear Fuel (SNF) codisposed with High Level Waste (HLW) glass, commercial SNF, and Immobilized Plutonium Ceramic (Pu-ceramic) codisposed with HLW glass. The scope of the model validation is to (1) describe the model and the parameters used to develop the model, (2) provide rationale for selection of the parameters by comparisons with measured values, and (3) demonstrate that the parameters chosen are the most conservative selection for external criticality risk calculations. To demonstrate the applicability of the model, a Pu-ceramic WP is used as an example. The model begins with a source term from separately documented EQ6 calculations; where the source term is defined as the composition versus time of the water flowing out of a breached waste package (WP). Next, PHREEQC, is used to simulate the transport and interaction of the source term with the resident water and fractured tuff below the repository. In these simulations the primary mechanism for accumulation is mixing of the high pH, actinide-laden source term with resident water; thus lowering the pH values sufficiently for fissile minerals to become insoluble and precipitate. In the final section of the model, the outputs from PHREEQC, are processed to produce mass of accumulation

The Marshall specimens were placed in a conventional oven for time and temperature conditions established on the basis of the environment factors of the region where the surface course is constructed by AC-20 from the Ing. Antonio M. Amor refinery. Volatilized material (VM, load resistance increment (ΔL and flow resistance increment (ΔF models were developed by the RSM. Cylindrical specimens with real aging were extracted from the surface course pilot to evaluate the error of the models. The VM model was adequate, in contrast (ΔL and (ΔF models were almost adequate with an error of 20 %, that was associated with the other environmental factors, which were not considered at the beginning of the research.

    Bernard-Champmartin, A.; Poujade, O.; Mathiaud, J.; Mathiaud, J.; Ghidaglia, J.M.

    2014-01-01

    We present here a model for two phase flows which is simpler than the 6-equations models (with two densities, two velocities, two temperatures) but more accurate than the standard mixture models with 4 equations (with two densities, one velocity and one temperature). We are interested in the case when the two-phases have been interacting long enough for the drag force to be small but still not negligible. The so-called Homogeneous Equilibrium Mixture Model (HEM) that we present is dealing with both mixture and relative quantities, allowing in particular to follow both a mixture velocity and a relative velocity. This relative velocity is not tracked by a conservation law but by a closure law (drift relation), whose expression is related to the drag force terms of the two-phase flow. After the derivation of the model, a stability analysis and numerical experiments are presented. (authors)

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M and O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    For any battery-powered vehicles (be it unmanned aerial vehicles, small passenger aircraft, or assets in exoplanetary operations) to operate at maximum efficiency and reliability, it is critical to monitor battery health as well performance and to predict end of discharge (EOD) and end of useful life (EOL). To fulfil these needs, it is important to capture the battery's inherent characteristics as well as operational knowledge in the form of models that can be used by monitoring, diagnostic, and prognostic algorithms. Several battery modeling methodologies have been developed in last few years as the understanding of underlying electrochemical mechanics has been advancing. The models can generally be classified as empirical models, electrochemical engineering models, multi-physics models, and molecular/atomist. Empirical models are based on fitting certain functions to past experimental data, without making use of any physicochemical principles. Electrical circuit equivalent models are an example of such empirical models. Electrochemical engineering models are typically continuum models that include electrochemical kinetics and transport phenomena. Each model has its advantages and disadvantages. The former type of model has the advantage of being computationally efficient, but has limited accuracy and robustness, due to the approximations used in developed model, and as a result of such approximations, cannot represent aging well. The latter type of model has the advantage of being very accurate, but is often computationally inefficient, having to solve complex sets of partial differential equations, and thus not suited well for online prognostic applications. In addition both multi-physics and atomist models are computationally expensive hence are even less suited to online application An electrochemistry-based model of Li-ion batteries has been developed, that captures crucial electrochemical processes, captures effects of aging, is computationally efficient

    In time series problems, noise can be divided into two categories: dynamic noise which drives the process, and observational noise which is added in the measurement process, but does not influence future values of the system. In this framework, we show that empirical volatilities (the squared relative returns of prices) exhibit a significant amount of observational noise. To model and predict their time evolution adequately, we estimate state space models that explicitly include observational noise. We obtain relaxation times for shocks in the logarithm of volatility ranging from three weeks (for foreign exchange) to three to five months (for stock indices). In most cases, a two-dimensional hidden state is required to yield residuals that are consistent with white noise. We compare these results with ordinary autoregressive models (without a hidden state) and find that autoregressive models underestimate the relaxation times by about two orders of magnitude since they do not distinguish between observational and dynamic noise. This new interpretation of the dynamics of volatility in terms of relaxators in a state space model carries over to stochastic volatility models and to GARCH models, and is useful for several problems in finance, including risk management and the pricing of derivative securities. Data sets used: Olsen & Associates high frequency DEM/USD foreign exchange rates (8 years). Nikkei 225 index (40 years). Dow Jones Industrial Average (25 years).

    2015-05-15

    We present the first realization of a "twin Higgs" model as a holographic composite Higgs model. Uniquely among composite Higgs models, the Higgs potential is protected by a new standard model (SM) singlet elementary "mirror" sector at the sigma model scale f and not by the composite states at m_{KK}, naturally allowing for m_{KK} beyond the LHC reach. As a result, naturalness in our model cannot be constrained by the LHC, but may be probed by precision Higgs measurements at future lepton colliders, and by direct searches for Kaluza-Klein excitations at a 100 TeV collider.

A time independent formulation of the basic equations is chosen. Construction of the average field in which particles move in a general independent particle model is developed, concentrating on problems of defining the average spherical single particle field for any given nucleus, and methods for construction of effective residual interactions and other physical operators. Deformed shell models and both spherical and deformed harmonic oscillator models are discussed in detail, and connections between spherical and deformed shell models are analyzed. A section on cluster models is included. 11 tables, 21 figures

    Full Text Available Besides analyzing capitalist societies historically and thinking of them in terms of phases or stages, we may compare different models or varieties of capitalism. In this paper I survey the literature on this subject, and distinguish the classification that has a production or business approach from those that use a mainly political criterion. I identify five forms of capitalism: among the rich countries, the liberal democratic or Anglo-Saxon model, the social or European model, and the endogenous social integration or Japanese model; among developing countries, I distinguish the Asian developmental model from the liberal-dependent model that characterizes most other developing countries, including Brazil.

  15. Modelling of Innovation Diffusion

    Directory of Open Access Journals (Sweden)

    Arkadiusz Kijek

    2010-01-01

    Full Text Available Since the publication of the Bass model in 1969, research on the modelling of the diffusion of innovation resulted in a vast body of scientific literature consisting of articles, books, and studies of real-world applications of this model. The main objective of the diffusion model is to describe a pattern of spread of innovation among potential adopters in terms of a mathematical function of time. This paper assesses the state-of-the-art in mathematical models of innovation diffusion and procedures for estimating their parameters. Moreover, theoretical issues related to the models presented are supplemented with empirical research. The purpose of the research is to explore the extent to which the diffusion of broadband Internet users in 29 OECD countries can be adequately described by three diffusion models, i.e. the Bass model, logistic model and dynamic model. The results of this research are ambiguous and do not indicate which model best describes the diffusion pattern of broadband Internet users but in terms of the results presented, in most cases the dynamic model is inappropriate for describing the diffusion pattern. Issues related to the further development of innovation diffusion models are discussed and some recommendations are given. (original abstract

  16. Nonlinear Modeling by Assembling Piecewise Linear Models

    Science.gov (United States)

    Yao, Weigang; Liou, Meng-Sing

    2013-01-01

    To preserve nonlinearity of a full order system over a parameters range of interest, we propose a simple modeling approach by assembling a set of piecewise local solutions, including the first-order Taylor series terms expanded about some sampling states. The work by Rewienski and White inspired our use of piecewise linear local solutions. The assembly of these local approximations is accomplished by assigning nonlinear weights, through radial basis functions in this study. The efficacy of the proposed procedure is validated for a two-dimensional airfoil moving at different Mach numbers and pitching motions, under which the flow exhibits prominent nonlinear behaviors. All results confirm that our nonlinear model is accurate and stable for predicting not only aerodynamic forces but also detailed flowfields. Moreover, the model is robustness-accurate for inputs considerably different from the base trajectory in form and magnitude. This modeling preserves nonlinearity of the problems considered in a rather simple and accurate manner.

    Since the early eighties, the international oil industry went through major changes : new financial markets, reintegration, opening of the upstream, liberalization of investments, privatization. This article provides answers to two major questions : what are the reasons for these changes ? ; do these changes announce the replacement of OPEC model by a new model in which state intervention is weaker and national companies more autonomous. This would imply a profound change of political and institutional systems of oil producing countries. (Author)

    1992-01-01

    A central issue in clinical radiobiological research is the prediction of responses to different radiation qualities. The choice of cell survival and dose-response model greatly influences the results. In this context the relationship between theory and model is emphasized. Generally, the interpretations of experimental data depend on the model. Cell survival models are systematized with respect to their relations to radiobiological theories of cell kill. The growing knowlegde of biological, physical, and chemical mechanisms is reflected in the formulation of new models. The present overview shows that recent modelling has been more oriented towards the stochastic fluctuations connected to radiation energy deposition. This implies that the traditional cell surivival models ought to be complemented by models of stochastic energy deposition processes and repair processes at the intracellular level. (orig.)

    The goal of the MDA is to produce software systems from abstract models in a way where human interaction is restricted to a minimum. These abstract models are based on the UML language. However, the semantics of UML models is defined in a natural language. Subsequently the verification of consistency of these diagrams is needed in order to identify errors in requirements at the early stage of the development process. The verification of consistency is difficult due to a semi-formal nature of UML diagrams. We propose automatic verification of consistency of the series of UML diagrams originating from abstract models implemented with our consistency rules. This Consistent Model Driven Architecture approach enables us to generate automatically complete workflow applications from consistent and complete models developed from abstract models (e.g. Business Context Diagram). Therefore, our method can be used to check practicability (feasibility) of software architecture models.

    The ATLAS Analysis Model is a continually developing vision of how to reconcile physics analysis requirements with the ATLAS offline software and computing model constraints. In the past year this vision has influenced the evolution of the ATLAS Event Data Model, the Athena software framework, and physics analysis tools. These developments, along with the October Analysis Model Workshop and the planning for CSC analyses have led to a rapid refinement of the ATLAS Analysis Model in the past few months. This article introduces some of the relevant issues and presents the current vision of the future ATLAS Analysis Model. Event Data Model The ATLAS Event Data Model (EDM) consists of several levels of details, each targeted for a specific set of tasks. For example the Event Summary Data (ESD) stores calorimeter cells and tracking system hits thereby permitting many calibration and alignment tasks, but will be only accessible at particular computing sites with potentially large latency.

  12. Modeling Complex Time Limits

    Directory of Open Access Journals (Sweden)

    Oleg Svatos

    2013-01-01

    Full Text Available In this paper we analyze complexity of time limits we can find especially in regulated processes of public administration. First we review the most popular process modeling languages. There is defined an example scenario based on the current Czech legislature which is then captured in discussed process modeling languages. Analysis shows that the contemporary process modeling languages support capturing of the time limit only partially. This causes troubles to analysts and unnecessary complexity of the models. Upon unsatisfying results of the contemporary process modeling languages we analyze the complexity of the time limits in greater detail and outline lifecycles of a time limit using the multiple dynamic generalizations pattern. As an alternative to the popular process modeling languages there is presented PSD process modeling language, which supports the defined lifecycles of a time limit natively and therefore allows keeping the models simple and easy to understand.

    Full Text Available Species distribution models are increasing in popularity for mapping suitable habitat for species of management concern. Many investigators now recognize that extrapolations of these models with geographic information systems (GIS might be sensitive to the environmental bounds of the data used in their development, yet there is no recommended best practice for “clamping” model extrapolations. We relied on two commonly used modeling approaches: classification and regression tree (CART and maximum entropy (Maxent models, and we tested a simple alteration of the model extrapolations, bounding extrapolations to the maximum and minimum values of primary environmental predictors, to provide a more realistic map of suitable habitat of hybridized Africanized honey bees in the southwestern United States. Findings suggest that multiple models of bounding, and the most conservative bounding of species distribution models, like those presented here, should probably replace the unbounded or loosely bounded techniques currently used [Current Zoology 57 (5: 642–647, 2011].

    The problems of statisfying similarity between a physical model and the prototype in rock wherein fissures and cracks place a role in physical behavior is explored. The need for models of large physical dimensions is explained but also testing of models of the same prototype over a wide range of scales is needed to ascertain the influence of lack of similitude of particular parameters between prototype and model. A large capacity centrifuge would be useful in that respect

    Rynders, Stefanie; Aksenov, Yevgeny; Feltham, Daniel; Nurser, George; Naveira Garabato, Alberto

    2016-04-01

    Exposure of large, previously ice-covered areas of the Arctic Ocean to the wind and surface ocean waves results in the Arctic pack ice cover becoming more fragmented and mobile, with large regions of ice cover evolving into the Marginal Ice Zone (MIZ). The need for better climate predictions, along with growing economic activity in the Polar Oceans, necessitates climate and forecasting models that can simulate fragmented sea ice with a greater fidelity. Current models are not fully fit for the purpose, since they neither model surface ocean waves in the MIZ, nor account for the effect of floe fragmentation on drag, nor include sea ice rheology that represents both the now thinner pack ice and MIZ ice dynamics. All these processes affect the momentum transfer to the ocean. We present initial results from a global ocean model NEMO (Nucleus for European Modelling of the Ocean) coupled to the Los Alamos sea ice model CICE. The model setup implements a novel rheological formulation for sea ice dynamics, accounting for ice floe collisions, thus offering a seamless framework for pack ice and MIZ simulations. The effect of surface waves on ice motion is included through wave pressure and the turbulent kinetic energy of ice floes. In the multidecadal model integrations we examine MIZ and basin scale sea ice and oceanic responses to the changes in ice dynamics. We analyse model sensitivities and attribute them to key sea ice and ocean dynamical mechanisms. The results suggest that the effect of the new ice rheology is confined to the MIZ. However with the current increase in summer MIZ area, which is projected to continue and may become the dominant type of sea ice in the Arctic, we argue that the effects of the combined sea ice rheology will be noticeable in large areas of the Arctic Ocean, affecting sea ice and ocean. With this study we assert that to make more accurate sea ice predictions in the changing Arctic, models need to include MIZ dynamics and physics.

  18. Crushed Salt Constitutive Model

    International Nuclear Information System (INIS)

    Callahan, G.D.

    1999-01-01

    The constitutive model used to describe the deformation of crushed salt is presented in this report. Two mechanisms -- dislocation creep and grain boundary diffusional pressure solution -- are combined to form the basis for the constitutive model governing the deformation of crushed salt. The constitutive model is generalized to represent three-dimensional states of stress. Upon complete consolidation, the crushed-salt model reproduces the Multimechanism Deformation (M-D) model typically used for the Waste Isolation Pilot Plant (WIPP) host geological formation salt. New shear consolidation tests are combined with an existing database that includes hydrostatic consolidation and shear consolidation tests conducted on WIPP and southeastern New Mexico salt. Nonlinear least-squares model fitting to the database produced two sets of material parameter values for the model -- one for the shear consolidation tests and one for a combination of the shear and hydrostatic consolidation tests. Using the parameter values determined from the fitted database, the constitutive model is validated against constant strain-rate tests. Shaft seal problems are analyzed to demonstrate model-predicted consolidation of the shaft seal crushed-salt component. Based on the fitting statistics, the ability of the model to predict the test data, and the ability of the model to predict load paths and test data outside of the fitted database, the model appears to capture the creep consolidation behavior of crushed salt reasonably well

    This Letter demonstrates that, as in flipped SU(5) models, doublet-triplet splitting is accomplished by a missing partner mechanism in flipped SO(10) models. The gauge group SO(10){sub F}xU(1){sub V'{sub F}} includes SU(2){sub E} gauge symmetry, which plays an important role in solving the supersymmetric (SUSY) flavor problem by introducing non-abelian horizontal gauge symmetry and anomalous U(1){sub A} gauge symmetry. The gauge group can be broken into the standard model gauge group by VEVs of only spinor fields; such models may be easier to derive than E{sub 6} models from superstring theory.

    The response matrix, consisting of the closed orbit change at each beam position monitor (BPM) due to corrector magnet excitations, was measured and analyzed in order to calibrate a linear optics model of SPEAR. The model calibration was accomplished by varying model parameters to minimize the chi-square difference between the measured and the model response matrices. The singular value decomposition (SVD) matrix inversion method was used to solve the simultaneous equations. The calibrated model was then used to calculate corrections to the operational lattice. The results of the calibration and correction procedures are presented

    Models of human behavior and cognition (HB and C) are necessary for understanding the total response of complex systems. Many such models have come available over the past thirty years for various applications. Unfortunately, many potential model users remain skeptical about their practicality, acceptability, and usefulness. Such hesitancy stems in part to disbelief in the ability to model complex cognitive processes, and a belief that relevant human behavior can be adequately accounted for through the use of commonsense heuristics. This paper will highlight several models of HB and C and identify existing and potential applications in attempt to dispel such notions. (author)

The model integrates evolutionary, static and dynamic views of information and highlights the relationship between symbolic content and the physical world. The model includes what information technology practitioners call “non-functional” attributes, which, for information, include information quality and information friction. The concepts developed in the model enable a richer understanding of Floridi’s questions “what is information?” and “the informational circle: how can information be assessed?” (which he numbers P1 and P12.

It is dual to another complex matrix model where the couplings of the first model are encoded in the Kontsevich-like variables of the second. The duality between the theories is mirrored by the duality of their Feynman diagrams. Analogously to the Hermitian Kontsevich- Penner model, the correlation functions of the second model can be written as sums over discrete points in subspaces of the moduli space of punctured Riemann surfaces.

    1983-01-01

    The IITRI Urban Fire Spread Model as well as others of similar vintage were constrained by computer size and running costs such that many approximations/generalizations were introduced to reduce program complexity and data storage requirements. Simplifications were introduced both in input data and in fire growth and spread calculations. Modern computational capabilities offer the means to introduce greater detail and to examine its practical significance on urban fire predictions. Selected portions of the model are described as presently configured, and potential modifications are discussed. A single tract model is hypothesized which permits the importance of various model details to be assessed, and, other model applications are identified

    In this note the author discusses the need for better air quality mobile source models near roadways and intersections. To develop the improved models, a better understanding of emissions and their relation to ambient concentrations is necessary. The database for the modal model indicates that vehicles do have different emission levels for different engine operating modes. If the modal approach is used information is needed on traffic signal phasing, queue lengths, delay times, acceleration rates, deceleration rates, capacity, etc. Dispersion estimates using current air quality models may be inaccurate because the models do not take into account intersecting traffic streams, multiple buildings of varying setbacks, height, and spacing

    With the advanced detector era just around the corner, there is a strong need for fast and accurate models of gravitational waveforms from compact binary coalescence. Fast surrogate models can be built out of an accurate but slow waveform model with minimal to no loss in accuracy, but may require a large number of evaluations of the underlying model. This may be prohibitively expensive if the underlying is extremely slow, for example if we wish to build a surrogate for numerical relativity. We examine alternate choices to building surrogate models which allow for a more sparse set of input waveforms. Research supported in part by NSERC.

    2013-01-01

    Simple Summary In this review paper we discuss the different modeling techniques that have been used in animal welfare research to date. We look at what questions they have been used to answer, the advantages and pitfalls of the methods, and how future research can best use these approaches to answer some of the most important upcoming questions in farm animal welfare. Abstract The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

    Critical evaluation of the adequacy of ecological models is urgently needed to enhance their utility in developing theory and enabling environmental managers and policymakers to make informed decisions. Poorly supported management can have detrimental, costly or irreversible impacts on the environment and society. Here, we examine common issues in ecological modelling and suggest criteria for improving modelling frameworks. An appropriate level of process description is crucial to constructing the best possible model, given the available data and understanding of ecological structures. Model details unsupported by data typically lead to over parameterisation and poor model performance. Conversely, a lack of mechanistic details may limit a model's ability to predict ecological systems’ responses to management. Ecological studies that employ models should follow a set of model adequacy assessment protocols that include: asking a series of critical questions regarding state and control variable selection, the determinacy of data, and the sensitivity and validity of analyses. We also need to improve model elaboration, refinement and coarse graining procedures to better understand the relevancy and adequacy of our models and the role they play in advancing theory, improving hind and forecasting, and enabling problem solving and management.

    This Ph.D. dissertation addresses ultrasound transducer modeling for medical ultrasound imaging and combines the modeling with the ultrasound simulation program Field II. The project firstly presents two new models for spatial impulse responses (SIR)s to a rectangular elevation focused transducer...... (REFT) and to a convex rectangular elevation focused transducer (CREFT). These models are solvable on an analog time scale and give exact smooth solutions to the Rayleigh integral. The REFT model exhibits a root mean square (RMS) error relative to Field II predictions of 0.41 % at 3400 MHz, and 1.......37 % at 100MHz. The CREFT model exhibits a RMS deviation of 0.01 % relative to the exact numerical solution on a CREFT transducer. A convex non-elevation focused, a REFT, and a linear flat transducer are shown to be covered with the CREFT model as well. Pressure pulses calculated with a one...

    Testing the applicability of mathematical models with carefully designed experiments is a powerful tool in the investigations of the effects of ionizing radiation on cells. The modeling and cellular studies complement each other, for modeling provides guidance for designing critical experiments which must provide definitive results, while the experiments themselves provide new input to the model. Based on previous experimental results the model for the accumulation of damage in Chlamydomonas reinhardi has been extended to include various multiple two-event combinations. Split dose survival experiments have shown that models tested to date predict most but not all the observed behavior. Stationary-phase mammalian cells, required for tests of other aspects of the model, have been shown to be at different points in the cell cycle depending on how they were forced to stop proliferating. These cultures also demonstrate different capacities for repair of sublethal radiation damage

    This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.

    Creation of new functional inorganic materials using micro-gravity environment was studied. Observation of an electrode interface phenomenon under micro-gravity clarified that time variation in interference fringe is dependent on current density and electrode thickness in ground experiment, while it is dependent on not electrode thickness but current density under micro-gravity. In fabrication of glass fine particles under micro-gravity, true spherical glass fine particles of 4-7{mu}m in size were obtained corresponding to a charge of 40mg by evaporation and solidification of sodium tellurate glass as raw material under micro-gravity. In fabrication of non-harmonic Pb-Zn system alloy, the homogeneous alloy texture of 5{mu}m level was observed which has never been observed in previous metal phase diagrams by fusion of 80atom%Pb-20atom%Zn mixture under micro-gravity and quenching from 500degC.

    For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)

    Rice being produced as food is taken up out of various types of biomass, and a feasibility study from the viewpoints of technology and economy is conducted as to its use in the energy industry. The production of ethanol from rice, though it has no past record worth discussion, is similar to the production of ethanol from other biomass resources in terms of technology and economy. The problem is that the production cost of rice is far higher than those of other materials. It is expected, however, that there will a large-scale production cost reduction and an increase in the yield when novel cultivation techniques are introduced in the future. It is also expected that alcohol from rice will be sufficiently competitive with alcohol from molasses or the like when the exploitation of cellulose-family by-products such as husks becomes feasible. The study on this occasion deals solely with the effective use of farmland and the surplus rice. A confrontation between rice as a biomass resource and rice as a food has to be avoided as much as possible in the long term because it may cause a price rise and compromise the security of food supply. That is, in discussing this matter, it is mandatory to draw a very definite line between rice as a food and rice as an alcohol production material. (NEDO)

    Imagining a space in the middle of the 21st century, a space station installed with the artificial gravity generation facility is constructed, and a space factory utilizing a gravity free environment is also constructed. The construction materials for the space structures of this kind are prepared from the resources of the Luna. A solar power generation satellite being arranged with the solar cells manufactured from a silicon of the Luna is allocated on a geostationary orbit, and a power generated is supplied to the earth by the microwave. In such a time, a regular liner to the Luna and a ferry boat to the Mars will have come to fly, and furthermore an oxygen used for the propellant to them as well will be supplied from the Luna. In order to realize such a conception, there are various problems to be overcome such as a transportation problem first of all, a long life problem in the Luna and Mars bases and so forth. Furthermore a consideration to the environmental conservation of the Luna and Mars is also required. The nature of the Luna without a crustal alteration, meteorological phenomena, and organisms has no force to restore an environmental destruction. As for a space development in the future, it is desired that it should not damage a nature of the space and should be a field to chase a possibility of the human beings for a long time. 30 refs., 14 figs., 1 tab.

    The result is reported herein of a depth transform algorithm application utilizing equi-traveltime planes in reflection seismic exploration for the purpose of knowing the structure configuration in front of the tunnel face in a tunnel excavation process. A vibration producing hole was provided 0.5m above the ground surface while a vibration receiving hole was provided at 1.5m above the ground surface, and the excavated lengths were 1.5m and 0.5m, respectively. There were 24 recording channels, from which inline offset records were taken. The on-site records were subjected to 100-1000Hz band pass filtering. The elastic wave propagation rate in the rock used for depth conversion was set at 400m/s in consideration of the distance and direct wave travel time from the vibration source to the vibration receiving point. As the result of study, weak layers were found in the neighborhood of 230-240m, 260-270m, and 280-290m. This method requires less core memory for calculation and completes calculation in a shorter period of time, which enables a conclusion that it will be effective in grasping the 3-dimensional structure in front of the tunnel face in the working scene. 4 refs., 7 figs.

    Studies were made for developing low-pollution easy-to-operate industrial furnaces for use in small and medium size plants in Indonesia. In this fiscal year, two kinds were selected out of Indonesia yielded brown coals, which were then subjected to test combustion in a bench scale fluidized bed combustor for examination for their combustion characteristics and environmental impact generating characteristics. The nitrogen oxides from the brown coals were found to mark approximately 100 ppm at an excess air ratio of 1.4, which was higher than in the case of bituminous coal. The NOx concentration level was found to be lower in the circulation fluidized bed boiler than in the spreader stoker fired boiler. Combustion efficiency exceeding 98% was achieved. A survey was conducted of brown coal users in various industrial fields in Indonesia. It was then concluded that the tested method not be recommended for use in small businesses in the textile industry because there would be no economic profit or improved efficiency for them but that it would be feasible in the plantation industry where the fluidized bed combustion/heat exchanger aided indirect process and the use of electrical dust precipitators would protect products from contamination.

Although various applications of large-scale solar furnaces are expected in the future, their current main applications are production of high-melting point materials, research on high-temperature physical properties, production of silicon, and solar heat power generation. A solar furnace is mainly composed of a parabolic reflector and heliostat plane reflector as optical system. It is necessary for practical industrial use of solar furnaces to study on furnace core design, profitability, installation site, temperature control, and reflector maintenance enough. (NEDO)

    Research, development, and evaluation were made on seawater purification for the purpose of supplying inexpensive city water stably in the future. In the research of the high flow rate long-tube type multi-stage flash process, basic characteristics were identified by studying fluidity, heat transfer, deaeration, and decarburization by using a test plant with a capacity of 3,000 m{sup 3}/d. A number of findings were derived in carrying out demonstration studies by using a test module with a capacity of 100,000 m{sup 3}/d. Research on heat transfer pipe materials covered a wide area including copper alloys, titanium and aluminum alloys, and ferrous materials, where a prospect was obtained on materials which may be practically usable in the future as transfer pipes in large seawater purifying equipment. Research on a concrete evaporator body proved that it is more economical than steel evaporators, and has sufficient corrosion resistance even against high-temperature brine. Other activities included researches on effects of contaminated seawater, brine diffusion, byproduct utilization, and total systems. Social and economic evaluations were also performed. (NEDO)

    Effectiveness of livestock industry wastes and vegetable protein added to fish meal in fish farming is tested by feeding the Japanese flounder. In the experiment, a part or the whole of the fish meal protein is replaced by the meat meal (MM), meat and bone meal (MBM), corngluten meal (CGM), or dried silkworm pupa meal (SPM), and fries of the Japanese flounder are fed on the new diets for eight weeks. On a diet containing 60% or less of MM, no change is detected in the fish in terms of increase in weight, protein efficiency ratio, and blood components, indicating that 60% at the highest of fish meal may be replaced by MM. In the case of MBM, it can occupy approximately 20%. As for CGM, the proper substitution rate is approximately 40%. Essential amino acids that the new diets may lack are added for an approximately 10% improvement on the result. The SPM substitution works up to 40%, when, however, the blood components are degraded. The proper substitution rate is therefore placed at approximately 20%. 38 refs., 2 figs., 17 tabs.

    VENUS Project aims at constructing a deepsea geomagnetic and electric fields observation station to cover the Ryukyu Trench, Philippine Sea, and Mariana Trough, by the reuse of the Okinawa-Guam commercial marine communication cable now out of service. This report deals with a scenario for the development of a geomagnetic/electric observation system as a part of the planned long-term sea bottom observation effort and the installation of equipment therefor. The first stage consists of the towing of a frame mounted with the system equipment and a cable to connect to a data transmission relay and their placement at a specified location on the sea bottom. The cable is extended toward the relay and its leading end is allowed to land near the relay. Next, a manned submersible vessel is used to connect the cable end to the relay, the submersible vessel is next driven along the connection cable toward the system equipment for the determination of the position and orientation of the system equipment, and then electrodes are arrayed at an interval of 20m into an L-letter configuration. The system will be established in March, 1998, on the 4200m-deep continental slope of the Ryukyu Trench approximately 90km southeast of Okinawa. 2 figs., 1 tab.

    As part of the (district energy-saving visions for City of Iwai), the feasibility study is implemented for citizen community facilities which utilize waste heat discharged from factories in the city. More concretely, those items studied include a heated pool, other community facilities and botanical garden of tropical plants which utilize waste heat of exhaust gas cooling water heated to around 70 degrees C by a desulfurization unit at a pulp factory. Case 1 includes the citizen community facilities (e.g., heated pool and bath facilities), and Case 2 includes a green house botanical garden, involving studies on facility scales, requirements of heat and recycling water, hot water supply, air conditioning, bath systems, and heating systems for green houses. It is estimated that the citizen community facilities have an energy saving effect of 640kL/y as fuel oil, which corresponds to saving of around 29 million yen/y, and CO2 abatement effect of 471t/y as carbon, and that the green house botanical garden has an energy saving effect of 669kL/y as fuel oil, which corresponds to saving of around 30 million yen/y, and CO2 abatement effect of 492t/y as carbon.

    The research and development project is implemented for the chemical processes which utilize supercritical fluids, in order to establish the basic technologies for the environment-friendly chemical processes. For the solvolysis, the conditions under which plastics are hydrolyzed in supercritical water are investigated, and the basic data are obtained for the optimum conditions under which thermoplastic resins are hydrolyzed. The mechanisms involved in hydrolysis of polymers in supercritical water are elucidated to some extent. The environment-friendly process for synthesizing polycarbonate in supercritical carbon dioxide gas is investigated, and the continuous flow sheets are established for securing almost 100% conversion in the presence of an inexpensive catalyst. For the oxidation, the tests are conducted to burn low-grade coal in supercritical water, and the conditions under which it is burnt without releasing acid and toxic gases are found. For the hydrogenation, heavy fuel oil is treated in supercritical water to produce the lighter products. The conditions under which light oils and gases are produced are clarified, and the basic data are obtained for producing light gases from the resultant coke as the by-product. (NEDO)

    Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

    An environmentally friendly refuse energy utilizing business, for which RDF (refuse derived fuel) produced out of wastes discharged by industries belonging to a Fujieda city environmental protection council will provide the heat source, is proposed by the said council. The proposal is subjected to a study, a basic plan is drafted, and a decision is made on its profitability. In the study, surveys are conducted on the actualities of wastes and of demand for heat, and specifications are worked out relating to transportation and storage of RDF, production of steam by an RDF-fired boiler, routing of pipes for transmitting the steam to the industries in the district, facility costs, operating costs, etc. It is found that the amount of RDF produced out of the wastes discharged by the council member industries is so small that it can meet the demand of only one industry and that, even if more wastes are collected from a wider area, the increased amount will but meet the demand of two industries and a hot water pool. It is found that the system will be economically feasible, however, if the shortage of RDF-generated energy is covered by an oil-fired boiler and thereby impartiality is established in steam distribution and steam production unit price is reduced. In view of the intensification of control over dioxin, etc., the business will be gaining profit in 2002 and after. (NEDO)

    An apparatus is developed to establish a system which allows utilization of hydrogen safely and easily, and its applicability to a hydrogen system for domestic purposes is tested. The system converts solar energy by the photovoltaic cell unit into power, which is used to generate hydrogen by electrolysis of water at the hydrogen generator, stores hydrogen in a metal hydride , and sends stored hydrogen to the burner and fuel cell units. It is found that a hydrogen occluding alloy of LaNi4.8Al0.2 stores hydrogen to approximately 80% when cooled to 20 to 25degC, and releases it to 10% when heated to 40degC. The fuel cell uses a solid polymer as the electrolyte. The hydrogen gas burner is a catalytic combustion burner with a Pt catalyst carried by expanded Ni-Al alloy. The optimum distance between the burner and object to be heated is 22mm. High safety and fabrication simplicity are confirmed for use for domestic purposes. The system characteristics will be further investigated. 4 refs., 8 figs.

    This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

    This paper introduces the circumstances and purpose of establishing the Basic Research Associate for Innovated Coal Utilization (BRAIN-C) Program started in October 1995, and the summary of the results therefrom in fiscal 1995. Although development of coal utilization technologies has been implemented over a number of years, there are many problems still requiring solutions. Early realization has been urged on diversification of coal utilization, acceleration of technological development and diversification of coal types. In order to achieve these goals, the necessity was recognized afresh on not only the hardwares, but also on basic technologies in terms of software which can identify properties of coals, systematize different reactions, and estimate reactions, fluidity and heat transmission of coals. Therefore, receiving a subsidy from the Agency of Natural Resources and Energy of the Ministry of International Trade and Industry, a research and development program to be implemented jointly by industries, administrative agencies and academic societies had been started with a five-year plan for the time being. With the activities for the program such as collecting 50 to 100 types of coals and supplying them to researchers, the program had been accelerated in fiscal 1995 on a large number of themes and results therefrom, including fundamental properties and thermo-chemical reactions. 2 figs., 4 tabs.

    This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

    This paper describes a possibility of geothermal utilization in Tomakomai City. The Tomakomai area has an extremely great amount of hot water existing in deep layers, leading to a consideration that it is very highly possible to develop the hot water. As seen from the underground structure and ground temperature gradient in the Tomakomai sedimentary basin, the development depth would be considerably great, being assumed to be about 2,000 meters. The acquisition amount per well is estimated 100 m{sup 3}/hour or more at 65 degrees C. Rise in petroleum price in the future is an unavoidable fate, hence geothermal water utilization has a fully bright future. The water has relatively low temperature, and is effective for use in room heating, hot water supply, and agricultural and livestock industries. It is worth considering utilization as a local energy system. It has also large secondary effects. According to the latest trial calculation, the unit price for hot water for room heating and hot water supply would be 10 to 20 yen per 1,000 kilo-calories. If the same amount of hot water should be supplied from a boiler, fossil fuel of 20,470 kl/year would be required. If converted by using a kerosene price of 75 yen per liter, the cost would be 1.3 billion 35 million yen, comparatively higher than the geothermal water utilization. (NEDO)

    Coal ash from the fluidized bed boiler is evaluated for its properties as is, as solidified or granulated, and as the roadbed material. The coal ash tested in the experiment is a mixture of ash from the fluidized bed boiler bottom, ash from the cyclone separator, and ash from the bag filter. In the manufacture of solid or granulated bodies, coal ashes are kneaded in water whose amount puts the mixture near the plasticization limit, are pressed in a low-pressure press and made into solid bodies by a 15-hour curing in 60degC saturated steam, and the solid bodies are crushed into solid granules. A content release test is conducted about the release of dangerous substances, and road paving experiments are conducted to learn the workability and serviceability of the granulated material as a road paving material. A study of the experimental results discloses what is mentioned below. Coal ash containing 10-20vol% of CaO and 15vol% or less of unburnt carbon turns into a high-strength solid after curing in saturated steam whose temperature is not higher than 60degC. The granulated solid satisfies the standards that an upper subbase material is expected to satisfy. It also meets the environmental standards in a release content test for soil set forth by Environment Agency notification No.46. 8 refs., 8 figs., 4 tabs.
