    Carbides of group IV transition metals such as ZrC, which are used as solar energy selective absorption film for solar energy collectors, has characteristics of absorbing light with a high energy of 0.6eV or more and of converting it to heat when exposed to light, and of not absorbing but reflecting light with a low energy of less than 0.6eV. By using ZrC as fabric materials, therefore, portable and durable heat absorbing and retaining materials can be produced. The authors have developed a solar energy absorbing and retaining fabric material, 'Solar [alpha]' (registered trade mark), which absorbs visible and near infrared rays and converts them to heat, and reflects heat from a human body and confines it. The use of Solar [alpha] has been found in various fields such as clothing as a new material for winter-sportswear, slacks, coats, and swimming suits. In this report, the heat absorbing and retaining mechanisms, basic properties of Solar [alpha], and the results of wearing tests are described. 12 refs., 6 figs., 3 tabs.

    The French Government most enthusiastically promotes development of bio-gasoline in renewable energy field. EU makes pressure to remove the French Government`s fiscal advantages for bio-gasoline which only benefit French farmers, and the IEA (International Energy Agency) report also estimates no benefit corresponding to the fiscal support cost. Start of the `Eolien 2005` project is attractive in renewable energy field which aims at construction of wind power generation stations of 250-500MW by 2005. The `Eolien 2005` project is mainly supported by Electricite de France (EDF) who guarantees the purchase of produced electric power at a submitted price. In addition to this subsidy activity, EDF decided to positively tackle renewable energy. On R and D efforts for renewable energy, France belongs to the most poor countries among IEA countries, and in addition, the effort is considerably concentrated onto the study on reduction of production cost for bio-gasoline. There were no changes in this situation in 1996. 7 refs., 5 figs., 31 tabs.

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

    This paper describes chlorination substituting disinfection technologies used in water purification systems. Chloramine treatment is regarded as effective in reducing trihalomethane (THM). Chlorine is injected in the initial stage in the form of free chlorine to disinfect pathogenic microorganisms in a short time, which is then added with ammonia to convert it into chloramine for further utilization. Chlorine dioxide has not been used in Japan, but introduced in Europe and America to treat THM. Ozone has the strongest oxidizing power, and is used for disinfection, virus inactivation, decomposition of THM precursors, and removal of fungus odor. The ozone treatment will produce aldehyde if an organic matter is present, but aldehyde can be removed by treatment using organismic activated carbon. Ultraviolet ray treatment has an advantage of being difficult of producing byproducts. This system was experimentally compared with free chlorine treatment on disinfection effect, mutagenicity, suppression of producing THM byproducts, and odor removal. In order to assure reliability of microorganismic and chemical safety in tap water supply systems, assurance by considering the entire system is important, not only by operating the disinfection units, but also combining such physical water purifying technologies as coagulation, sedimentation, filtration, and membrane treatment. The use of chlorine substituting disinfectants is also a part of the conception. 6 refs., 8 figs., 5 tabs.

    For the econometric analysis of petroleum substitution energy, a domestic econometric model was developed which can concretely and econometrically grasp and analyze effects of measures taken for environmental policies, energy conservation, promotion of new energy, etc. The model was made so synthetic as to catch a relationship between energy supply/demand and changes of econosocial structures in economic growth, industrial structure, life style, etc. which are extremely important elements for catching future energy demand. The model is composed of a secondary energy price model, a new energy introduction model, and an energy supply/demand model. As case parameters, selected were the price of crude oil, introduction of new energy, GDP and energy conservation, and the following cases were assumed: standard case, high price energy case, new energy introduction promotion case, low economic growth case, energy conservation case, and low energy demand case. The results of simulating each of these cases were indicated. 91 figs., 110 tabs.

    The paper conducted the modeling on the economic/industrial structure giving the economic frame for energy supply/demand forecast, and made some simulations. In the simulation, assumed were a standard case, aging/hollowing case, and technical innovation case. As to macroeconomic models, macro items such as the economic growth rate, prices and IS balance were determined by giving foreign factors, financial factors, population factors, etc. In long-term energy supply/demand models, data on demand by use in commercial/residential and transportation sectors were estimated using various statistics. About the calculation result of a standard case of the former sector, the existing industries which markedly ebbed are primary products, the material system, construction/civil engineering, etc. Contrarily, the production industry such as general machines, electrical machines and automobiles increased the share. New and highly growing industries are new production industries like electronics and communication and new services like finance, insurance and communication. The GDP rate grows by 2.3% per year on average and lowers in each ten years hereafter. 53 figs., 83 tabs.

    For further improvement of iron system materials, supermetals with ultimate characteristics were researched. Since their strength and toughness have been improved with grain refinement by thermomechanical treatment, improvement of single-phase steel is nearly completed, and the study on ultra-fine multi-phase steel is indispensable. Bulky materials are also restrained from grain refinement because of the capability of existing processing facilities. Making a breakthrough in such restraint requires a challenge to high-speed rolling, repeated shear deformation and ultra-high strain rate process beyond conventional technologies. Further improvement of microstructure and dynamic characteristics requires other energies such as magnetism as well as mechanical energy. {gamma}-{alpha} phase transition important for structure control of steel materials is dependent on magnetism. The study on structure control and characteristics improvement under ferromagnetic field is essential in the future. Material improvement such as reduction of impurities and circulating elements, environmental measures, and mechanical alloying remain as issues to be studied. 224 refs., 176 figs., 18 tabs.

    A `laminated rubber tile` and a `shock absorbing holed-in anchor` were devised in connection with the apron of a dam for a hydroelectric power plant. As the result of a survey on the hydroelectric power plants, ten plus places were observed where a general kind of concrete was severely worn in the company territory; but, there were substantial number of rubber materials that had still been sound for over ten years after the installation. In spite of the soundness of the rubber tiles, however, it was observed that their anchor supports had been cut and separated. An abrasion comparison test of concrete and rubber materials revealed that the rubber materials were considerably superior in abrasion resistance. Various rubber tiles were tested for abrasion resistance, tear strength, tensile strength, impact strength, etc.; and methods for fixing rubber tiles were also tested such as a holed-in anchor, chemical anchor and adhesives. As a result, a laminated rubber tile was designed with its upper layer constituted of a rubber sold on the market and its lower layer of a fiber reinforced rubber also on the market, and so was a shock absorbing type holed-in anchor. 1 ref., 11 figs., 4 tabs.

    In order to find the higher critical strength, toughness and corrosion resistance of Al system materials than those obtained by conventional methods, crystal grain control was studied in a finer-grain region. The above characteristics of Al materials obtained by conventional technologies such as alloy element addition and heat treatment controlling crystal grains of several tens {mu}m are approaching critical values, resulting in poor characteristics for the latest needs. It has been confirmed experimentally in fundamental studies using small specimens that fine crystal grains of several {mu}m can remarkably enhance the above characteristics. Technology for creating mesoscopic structure-controlled materials was thus studied. In particular, creation of ultra-fine advanced Al alloy bulk materials by cryogenic processing method was selectively studied. The developmental approach and its issue were thus revealed for creating mesoscopic crystal structure by recovery and recrystallization of a highly distorted state obtained by cryogenic processing. 102 refs., 80 figs., 8 tabs.

    Aluminum materials were surveyed to improve aluminum materials drastically so as to play an important role as prospective materials in response to the changing social environment. Aluminum materials have become the following metal materials to iron materials due to their light weight, durability, and profitability. Based on their merits and demerits, it was made clear how the aluminum materials contribute to the future resource saving, energy saving, and global environmental protection. Review was made on the two research and development themes which contribute to the creation of super metals. Hence, the themes proposed are focused on the creation of new aluminum mill products with ultra fine grain structure using very low temperature processing and on the creation of super-formability aluminum alloy sheets by advanced texture control using processing which can enhance the shearing stress. Results of the research and development are expected to provide wide applicability for other metals, ceramics, and polymers. 433 refs., 315 figs., 56 tabs.

    In East European countries (Albania, Bulgaria, Czech, Slovakia, Hungary, Poland, Rumania and former Yugoslavia), energy prices were raised as part of the general price reform in the initial stage of the economic reform. Trade regulations on energy products were relaxed, and prices of tradable energy products were made free. Even in countries such as Rumania and Bulgaria where there still remain controls, the governments aim at perfect liberalization. Thus, this paper first considered the energy situation of East European countries where economy and society are now changing. Described were the overall economy situation and energy supply/demand in East European countries. Next, the paper detailed the energy situation in Hungary and Poland. In conclusion, the paper considered energy and international cooperation, and Pan-european Energy Charter which are important future issues in the energy sector of East European countries. 10 refs., 36 figs., 26 tabs.

    The paper investigates and reports the trend of the development of petroleum substitution energy in the U.S. The Clean Coal Technology Plan is one of the plans which were implemented most successfully in the past several years. The plan made a remarkable reduction in NOx and SOx emissions possible. As for natural gas, importance is placed on improvement of production/storage technology of natural gas and high-effective low-NOx-emission turbines. As to the research on nuclear reactors, importance is now placed on the light water reactor plan, and the target is the design and development of such nuclear reactors as electric power companies pay attention to. The solar cell industry is markedly developing, and the shipment grows 17% per year. However, the price is rapidly declining. The wind turbine and biomass power generation plans are also advanced, and most of the plans are aimed at the development of new fields of application. With regard to geothermal energy, slowness is seen. Concerning electric vehicles, no makers enter into the quantity production, but the research and development are actively being made. 72 refs., 26 figs., 51 tabs.

    The paper investigates and reports the developmental trend of petroleum substitution energy in Germany. Policies for the technical development and actual introduction of petroleum substitution energy in Germany are concerned with three energies: coal, natural gas, and new energy, except nuclear energy the use of which is against public opinion. Coal is the only abundant domestic resource, but not internationally competitive because of its cost. Brown coal obtained from the open pit mining is an abundant and low-cost domestic resource, but has the environmental problem. The latest technology is actually being introduced in which the thermal power generation is integrated into gasification, and the gas/steam turbine power generation. Natural gas is advancing in the use as energy source for space heating substituting for brown coal. The technology development of new energy is promoted mainly on such wind power and solar energy as are called renewable energy. As to the development of technology using renewable energy for which the rapid increasing use is not expected in near future, the target is directed mostly to CO2 control and the third world where there are no public electric power nets. 30 refs., 10 figs., 8 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.

    This report summarizes the fiscal 1999 research result on simulation analysis on petroleum substituting energy. The simulation model for analyzing social and energy supply and demand structures comprehensively was established by improving the China and Korea models developed in fiscal 1998 through a use of input-output tables. In simulation of the China model, the reference case showed that a primary energy demand in 2030 reaches 3.3 times as much as that in 1997 (2.9 times in CO{sub 2}), resulting in serious energy and environment problems. Reduction of primary energy and CO{sub 2} is possible by promotion of energy saving and introduction of a carbon tax. In simulation of the Korea model, the reference case showed that CO{sub 2} emission in 2030 reaches 2.2 times as much as that in 1997, showing an annual increase rate of 2.4%. The annual increase rate can be reduced by introducing a carbon tax. The simulation model for automobile energy was also established for major countries in Asia. Automobile energy consumption increases with diffusion of automobiles until 2030 gradually. In particular, the consumption in China reaches that in Japan in 2010. (NEDO)

    The paper investigates and reports policies for and the developmental trend of petroleum substitution energy in the E.U. The technology of 18 wind turbine makers in West Europe is on a level that they can almost sell MW-class turbines for practical use. The wind turbine industry in Denmark is on a level of No.1 of the world, and occupies approximately 50% of the world market share. The capacity of the wind power generation in Germany which finished the installation at the end of 1995 exceeded 1000 MW. EEWC has recently been established as an organization for using waste as energy. Municipal solid wastes discharged in West Europe are regarded to be equivalent to 5% of all the power demand there. In Spain, biomass is a petroleum substitution energy source which is most used. A target amount for the use set by the government is equal to 427000 tons in oil. Biomass is most used in the residential field, and it is mainly the use of agricultural and forestry wastes as fuel. Rapeseed oil is studied as fuel for bio car. In Denmark, production of rapeseed as fuel use crop is increasing. 14 refs.

    Supermetal with critical characteristics is under advanced investigation for further improvement of metal materials. Although iron is most frequently used as structural material among various metals, it should be used more carefully and effectively because of resource limitation and global environmental problem. It is essential to draw various excellent properties much more from iron and to improve recyclability. In particular, the best way to meet these requirements is achievement of more fine structure and higher purity. Since the lowest crystalline grain size is now limited to nearly 10{mu}m, metallic structure composed of grains below 1{mu}m is expected by mesoscopic control. Various methods have been studied to achieve ultra-fine crystalline structure, and study of precise heat treatment control and ultra-strength metallurgy is required. Heat treatment in magnetic field and layered structure by mechanical alloying are also promising. Drastic enhancement of characteristics is expected for heat resistant steel by combining of high purity with fine structure. 299 refs., 166 figs., 18 tabs.

    Since the early stage of the development of the prestressed concrete (PC) manufacturing techniques, it has been said that forming a single PC structure by uniting precast segments with PC steel material into one is a construction method making the most of the feature of PC. This paper roughly describes the history of the development of PC and concrete examples of PC, centering on the construction techniques effectively utilizing the principle of PC and its materials. Especially, a PC bridge is superior to a steel bridge with respect to noise and vibration, so that the construction works of replacing railway steel bridges and railway elevated bridges by PC bridges have come to be seen in many places recently. In order to increase the span of a PC bridge, the reduction of the weight is a major factor. Therefore, an outer cable system has come to be used so as to reduce the thickness is cross section of the web of a PC beam as much as possible. The changes of the maximum span of cable stayed bridge are listed in a table in comparison of PC bridges with steel bridges. 29 refs., 9 figs., 1 tab.

    In the last twenty-five years, the level of social recognition for the importance of energy conservation grew progressively from a total nonexistence of concern to the driving force that ensures the future environmental health of the nation and the world. Executive Order 12003, relating to energy policy and conservation, was signed by President Jimmy Carter and dated July 20, 1977. In 1992, President Clinton issued Executive Order 12759 - federal Energy Management. Each agency will prescribe policies under which its industrial facilities in the aggregate increase energy efficiency by at least 20% in fiscal 2000 in comparison to fiscal 1985. Current Federal programs for building efficiency are estimated to result in 31.5 billion dollars in annual energy saving for consumers by 2010. Future trends attract attention. The major programs currently in force to implement these policies and directives include Rebuild America, Million Solar Roofs Initiative, Home Energy Rating Systems, and Weatherization Assistance Program. 37 refs., 1 fig., 6 tabs.

    Blair`s cabinet of the UK, as soon as it was formed, started a review of all policies of the past Conservative government, including the area of energy and environment. The Labour Party has already underlined its commitment to promoting petroleum substituting, i.e., renewable energy. The government made clear that the unique British NFFO Scheme to promote sources of renewable energy would continue and in November, 1997 published the policy guide for the fifth round of NFFO bidding. The British energy market is generally considered to be the most liberalized for free competition in Europe and even the retail market for households is going to be completely open for competition in electricity and gas supply by 1998. As to the regulation of the green house gas exhaust, the Labour Party has put forward a target to cut 20% of the exhaust level of 1990 by the year 2010. The government is now preparing measures for its implementation. At present, the EU is debating the draft of the landfill directive. In the UK, the construction of waste incineration and power generating plants with modern technology is now being promoted. 27 tabs.

    The present developmental conditions of petroleum substituting energies in the U.S.A. were surveyed. The budget related to energy saving and petroleum substituting energies in the U.S.A. is on the increase. DOE`s expenditure on petroleum substituting energies increased from $6.8 billion in 1993 to $8.1 billion in 1995 (from 29.6% to 34.6% of DOE`s expenditure), showing the positive approach to development of petroleum substituting energies. Approaches to environmental protection are also in promotion such as positive use of electrical vehicles by U.S. government and emission regulation of specific pollutants by EPA. The state of California withdrew the regulation which prescribes that 2% of passenger cars sold in the state should be zero emission vehicles after 1998, because development of the battery with both sufficient mileage and output is impossible by 1998 in the present stage. The prospect of practical use of new batteries such as lithium battery is still far from certain for some years. Development of petroleum substituting energies in the U.S.A. is still insufficient. 17 refs., 1 fig., 4 tabs.

    The project aims to develop a biocatalyst-assisted synthesizing method for efficiently manufacturing sugar containing polymers and polylactic acids which generate less environmental impact. The ALP-901 derived from actinomycetes operates best with 5% water content, and remains free of hydrolytic effect even when the rate rises to 20%, and catalyzes transesterification only. The esterification activity of bioprase rose remarkably upon addition of water. A polymer with a molecular weight of scores of thousands was obtained in the polymerization of sugar ester monomers. A sugar undecylenate with a double bond at an end was successfully polymerized. The sugar containing polymer exhibited excellent biodegradability. In a reaction of butanediol and lactide, several types of lactic oligomers different in molecular weight were synthesized. The oligomers were caused to react with divinylcarboxylic acid in the presence of an enzyme, and a polymerizable lactic oligomer was obtained. Furthermore, in a reaction between glucose and lactide, several lactic oligomer derivatives were synthesized, different in molecular weight. In a reaction of the derivatives and divinylcarboxylic acid with an enzyme added thereto, a polymerizable lactic oligomer derivative was obtained, which was brought into polymerization in the presence of a radical polymerization initiator for the production of a high molecular weight gel.

    In relation with coping with global environmental problems in recent years, needs are increasing more than ever for enhancing fossil energy utilization rates, developing and expanding utilization of petroleum substituting energies that can substitute fossil energies. Since Japan is particularly a large energy consuming country, and cannot escape from depending on import for the majority of its energy resources, it is an urgent issue to enhance the energy utilization efficiency and further promote development and utilization of new energies. To do this, it is indispensable to exchange such item of information as identification of actual status in other countries of handling the petroleum substituting energies. Taking up geothermal energy, fiscal 1998 invited four experts from EU countries. Visits were made for about two weeks on Japanese research institutes and business enterprises related to geothermal energy, and opinions and information were exchanged. A seminar was held on the final day, where the EU experts have made presentations on the current status and future prospects on geothermal research and development in EU. Greatly valuable suggestions were given for the Japan's future geothermal research and development. (NEDO)

    A survey was carried out to make available the information base that can collect, put into order and provide quickly and accurately the energy related information based on global environment problems in the Pacific Ocean region. Fiscal 1998 has performed a substituting energy demand and supply analysis in the Pacific Ocean region by adding the 1996 data, in addition to collection of the normal energy data. For the purpose of analyzing the petroleum substituting energy demand and supply in the Pacific Ocean region, data were collected from 17 countries for fiscal 1997 and the quarterly data for 1998. Retroactive data collection was also continued. The growth rate of primary energy supply in the Pacific Ocean region is 1.8% in average in the 1980's, and 3.8% in the 1990's. In contrast, the growth rate of petroleum substituting energies is 6.4% in the 80's and 6.2% in the former half of the 90's, being far higher than the growth rate of the primary energy supply. The share of the petroleum substituting energies accounting for in the primary energy supply has increased from 6.7% in 1980 to 12.1% in 1996. As the breakdown, nuclear power accounts for overwhelmingly large, followed by geothermal energy and new energies. (NEDO)

    Performance of two-stage compression and cascade heating heat pump cycle was evaluated in the case using alternative refrigerant, HFC-134a, instead of CFC-12 through calculations and experiments. Heat source and heat load temperature conditions of CFC-12, HFC-134a, and HCFC-22 were calculated. As a result, this cycle provided equivalent coefficient of performance to use of CFC-12 and HCFC-22. Especially for HFC-134a, discharge gas temperature from compressor was much lower than that of the others, which prevented the heat decomposition of refrigerant. It was found that HFC-134a was suitable refrigerant for high temperature output equipment like this cycle. To grasp the possibility of hot water supply at 65 {degree}C and behavior of lubricating oil which can not be obtained only from calculations, applicability of HFC-134a was investigated. Experiments were conducted using a small test apparatus with electric input of 2 kW. As a result, satisfactory performance was obtained for each evaluation item. Applicability of HFC-134a to the two-stage compression cycle was confirmed. 9 refs., 21 figs., 16 tabs.

    The technique now in use for disinfecting municipal sewerage is the free chlorine method, and the free chlorine reacts with ammonia in the treated water for the formation of NH4Cl. The resultant compound is strongly toxic and harms aquatic organisms, this creating a knotty problem to solve. In this report, a bioassay utilizing Porphyra yezoensis conchospores is performed, and the toxicity reducing effect is discussed of the seaweed on water specimens disinfected by free chlorine, chlorine dioxide, ozone, and ultraviolet rays. Porphyra yezoensis is easy to acquire, and the bioassay evaluates the toxicity of the water specimens by evaluating the survival rate of conchospores discharged by free-living conchoceles and the rate of inhibited sprouting. The outcome is summarized below. The injection dose required for inactivating 99.9% of the groups of coli bacteria in the treated water and the trend of fluctuations in the concentration level are obtained. No inhibition of conchospore sprouting occurs even with the addition of 100% of treated water in the chlorine-disinfected specimen or chlorine dioxide-disinfected specimen. 19 refs., 8 figs., 2 tabs.

    The Pacific region is a densely populated region where economy is developing at a high pace with China and other newly industrialized economies at the core. When energy balance in the region is studied, it is found that China and some others have already turned pure importers of energy and that probabilities are high that, along with development of economy and improvement on living standards, all the nations in the region will become pure importers. Accordingly, in the presence of urgent problems of global pollution and oil resources depletion, it is important to make sure that data particularly about the development of substitute energies for oil in this region be collected and duly dealt with for accurately predicting future developments. In this survey, a database is to be built to grasp the trends of energy supply and demand with attention focused on substitutes for oil which are available at hand. In this fiscal year, data for 1997 were added to the database for analysis into demand and supply of substitutes for oil in the Pacific region, and energy data were gathered for this purpose. Detailed tables of balance were compiled, broken down by energy source. Other detailed tables of balance were also prepared, these broken down by ultimate consumption department. (NEDO)

    The paper described the FY 1999 results of the study of atomic technology. Using a combined system of the scanning tunnel microscope (STM) with the field ion microscope and the atom probe (AP), a few Ag atoms were identified. Si windows were formed by electron beam irradiated from a STM tip, and Ge nanocrystal array was formed at the windows by supplying GeH4 gas. Iron clusters were deposited on Si substrates. With those as nuclei and in self-formation for etching masks, Si pillar distribution nano-crystals were etching-processed. The oxidation process of clean Si surface using ultra-high vacuum electron spin resonance was observed, and the incomplete state of the Si oxidation process was observed. Perovskite oxide superlattices composed of the two kinds were fabricated using the laser ablation method. The layer type antiferromagnetic spin arrangement is artificially modulated in the superlattices along the stacking direction. To observe the magnetic nano-structure, the development was commenced of a spin-polarized STM. The paper theoretically analyzed the dynamic process of atoms and molecules. (NEDO)

    The personal computer is taken up as a sample, and studies are conducted about a system for separating and recovering recyclable materials. For the high-speed cutting and crushing of materials and their compaction, a water-jet cutting method is employed, which enables the unification of chip sizes after cutting, the prevention of dust generation, and the realization of clean working environments. For the separation of copper wires from their coats, a high-speed peeling machine is developed, and the copper wires are recovered for reuse. Fluorine plastics and polyester resin that constitute the coats do not show deterioration in their resin properties when put back into use. As for the powder resulting from the crushing of print circuit boards, it produces gas and unburnt carbon when subjected to heat treatment at 600 degrees C in inactive gas. The problem to arise from this recovery method is how to lower the cost. The separation of pelletized polymers and metal constituents can be accomplished by changing the ablation generation limit energy level during excimer laser irradiation, and this allows them to be recycled.

    In this biogasification process, coal is subjected to pretreatment and then experiences methane fermentation. The aim is to reduce the amount of CO{sub 2} per unit thermal equivalent to be generated by low coalification degree coal. The electrolytic oxidation technology for coal pretreatment is developed jointly with ESC (Electrosynthesis Company, Inc.), U.S. For the development and improvement of electrolytic oxidation technology, the experimenting electrolytic tank of ESC and a small-scale electrolytic oxidation unit developed by the same are used. Using the developed electrolytic oxidation technology, coal is made meltable at a rate of 2.93%/min, which means that 80% or more of the coal turns meltable in 30 minutes. The technology has its own problem, however, that the power consumption rate is high. The report comprises nine chapters, including (1) the goal and background of research and development, (2) enhancement of research and development, (3) electrolytic oxidation of low coalification degree coal, (4) methane fermentation, (5) prospect of practical application, (6) reference materials and list of literature, and (7) reports on research tours overseas.

    Research and development has been made on a cover soil replacement process utilizing waste papers for final disposal facility and a soil flow-out prevention process. This paper summarizes the achievements in fiscal 2000. In evaluating waste paper fibers and waste paper binder films, the safety level was assumed sufficiently high if the fibers are used for the cover soil replacement process for final disposal facility. However, films may have a possibility of destruction if force is applied by such as heavy machines running on the films, hence it must be avoided. According to the on-site scattering test using unattended mixed slurry spraying machine capable of being remotely controlled, the coverage was found good, and scattering of incineration residues can be prevented completely. With regard to monitoring of hydrogen sulfide gas, a system having a hydrogen sulfide sensor and GPS mounted on a slurry spraying machine capable of remote control operation was completed, and its usefulness was verified. By using a wastes disposal facility simulating device, investigations were performed on effects on seepage water and wastes when the cover soil replacing material utilizing waste papers is used, and on changes in the properties of the cover soil replacing material.

    Research and development have been carried out with an objective to re-utilize waste cable covering materials as oil substituting energy. The research has been performed on behavior of chlorine and lead being substances that impede making the cable covering materials into fuel, development of a technology to remove chlorine, lead and copper, and pelletizing properties for fuel making. In the study of behavior of chlorine and lead, the following matters were made clear: dechlorination reaction completes within 30 minutes if pyrolysis temperature is higher than 300 degrees C; the more the amount of filler CaCO3 in test samples, the less the dechlorination amount; and secular deterioration does not affect the dechlorination amount. A technology has been developed successfully to remove the substances that hinder making the cover materials into fuel, achieving the target values of copper at 0.2% or less, lead at 0.3% or less, and chlorine at 5% or less. In developing the pelletizing technology that puts the cover materials into raw materials for blast furnaces, dechlorination rate of 90% was achieved by mixing coke/PVC at a ratio of 1/1 and dechlorinating it by using a rotary kiln. It was verified that the product is free of problems in particle size as the blast furnace raw material. (NEDO)

    Mild traumatic brain injury (mTBI), also referred to as concussion, remains a controversial diagnosis because the brain often appears quite normal on conventional computed tomography (CT) and magnetic resonance imaging (MRI) scans. Such conventional tools, however, do not adequately depict brain injury in mTBI because they are not sensitive to detecting diffuse axonal injuries (DAI), also described as traumatic axonal injuries (TAI), the major brain injuries in mTBI. Furthermore, for the 15 to 30% of those diagnosed with mTBI on the basis of cognitive and clinical symptoms, i.e., the “miserable minority,” the cognitive and physical symptoms do not resolve following the first three months post-injury. Instead, they persist, and in some cases lead to long-term disability. The explanation given for these chronic symptoms, i.e., postconcussive syndrome, particularly in cases where there is no discernible radiological evidence for brain injury, has led some to posit a psychogenic origin. Such attributions are made all the easier since both post-traumatic stress disorder (PTSD) and depression are frequently co-morbid with mTBI. The challenge is thus to use neuroimaging tools that are sensitive to DAI/TAI, such as diffusion tensor imaging (DTI), in order to detect brain injuries in mTBI. Of note here, recent advances in neuroimaging techniques, such as DTI, make it possible to characterize better extant brain abnormalities in mTBI. These advances may lead to the development of biomarkers of injury, as well as to staging of reorganization and reversal of white matter changes following injury, and to the ability to track and to characterize changes in brain injury over time. Such tools will likely be used in future research to evaluate treatment efficacy, given their enhanced sensitivity to alterations in the brain. In this article we review the incidence of mTBI and the importance of characterizing this patient population using objective radiological measures. Evidence
