Bio-technologies including the biological CO2 fixation technology, or the green bio-technologies (GBT) are the technologies indispensable in realizing the change to a resource circulating and environment harmonizing society that accompanies economical growth, or in other words, the 'sustainable development'. In quantifying the feasibility of these technologies, the GBTs that contribute to creating Japan's international competitive power and employment were specified, and an approach to establish the realization target in 2010 was adopted, upon identifying the general condition of the related markets inside and outside the country. The GBT is the technology that makes the best use of Japan's independent strength created by combining the enzyme engineering and fermentation engineering with the 'genome science' (HEART). The targets are to substitute four million kiloliters of petroleum with a resource circulation type energy generated by the bio-technology; apply the bio-technology to about 30% of products and processes produced or used in Japan's chemical industries; and aim at creating markets by using environmental measurement and analysis, treatment of hard-to-decompose substances, and supports on tree planting as the three pillars.

Se analiza detalladamente los volúmenes de nado propuestos por el Programa de Preparación del Deportista (PPD, donde se aprecia que los atletas de la provincia no logran cumplir lo indicado por el mismo, siendo el inicio tardío en la práctica del deporte, la carencia de piscinas con un funcionamiento estable y las bajas temperaturas en el periodo invernal, los que más afectan el proceso. Provocando esto que no se alcancen resultados satisfactorios y con ello desmotivación y deserción por parte de los alumnos. La aplicación de los nuevos volúmenes inferiores a los PPD nos permitió obtener una mejor progresión y resultados satisfactorios en los eventos que se participa en las distintas competencias.

A hemoglobina e as células vermelhas do sangue em 1,5 BL s–1 aumentaram 24% e 18% respectivamente; o hematócrito foi 17 % maior em todos os peixes exercitados; o conteúdo de proteína do músculo branco em 1,0 BL s–1 foi 2% maior; a deposição de lipídio no músculo vermelho em 1,0 BL s–1 foi 22% maior e a retenção de água foi 3% menor. Os níveis de energia bruta aumentaram 10% em todos os peixes exercitados; a retenção de água no fígado foi 6 % menor em 1,0 BL s–1; a composição de lipídio no fígado foi 29% maior do que o controle e 34% maior do que a 1,5 BL s–1; a energia bruta no fígado aumentou em 1.0 BL s–1 comparada com o controle e 2,5 BL s–1. A deposição de lipídio no músculo ventral foi 9% maior em 2,0 BL s–1. Embora alta deposição de lipídio em matrinxã tenha sido obtida em velocidades moderadas de nado, os lipídios podem ser a fonte de combustível principal para manter as exigências metabólicas de matrinxã em exercício. A melhor velocidade de nado para obter o melhor crescimento em matrinxã está entre 1,0 e 1,5 BL s–1.

Full Text Available Serotonin plays a role at the pathophysiology of depression in humans and in experimental models. The present study investigated the depressive behavior and the weigh evolution in adult rats (60 days treated from the 1st to the 21st postnatal day with fluoxetine, a selective serotonin reuptake inhibitor (10 mg/kg, sc, daily. The depressive behavior was induced by the forced swim test (FST. The animals were submitted to two sessions of FST: 1st session for 15 min and the 2nd session 24h later, for 5 min. During the 2nd session the Latency of the Attempt of Escape (LAE and Behavioral Immobility (BI were appraised. The Fluoxetine group when compared to the Control group, showed an increase in LAE and a decrease in BI. The neonatal administration of fluoxetine reduced the depressive behavior in adult rats, possibly by increase in the brain serotonergic activity. This alteration can be associated to process of neuroadaptation.Estudos em humanos e em modelos experimentais demonstram que a serotonina (5-HT participa da fisiopatologia da depressão. O presente estudo investigou o comportamento depressivo e a evolução ponderal de ratos adultos jovens (60 dias tratados do 1º ao 21º dia pós-natal com fluoxetina, um inibidor seletivo de recaptação da serotonina, (10 mg/kg, sc, diariamente. A depressão experimental foi induzida através do teste de nado forçado (NF. Os animais foram submetidos a duas sessões de NF, a primeira por 15 min e a segunda após 24 h, por 5 min. Durante os 5 min de NF a latência da tentativa de fuga (LTF e o tempo de imobilidade (TI foram avaliados. O grupo tratado com fluoxetina apresentou aumento da LTF e redução do TI comparado ao controle. A administração neonatal de fluoxetina reduziu o comportamento depressivo em ratos adultos, possivelmente em função do aumento da atividade serotoninérgica cerebral. Esta alteração poderá estar relacionada a processos neuroadaptativos.

Entretanto, o ambiente de cativeiro é muito mais pobre em termos de estímulos fornecidos aos animais alojados no seu interior. Numa tentativa de remediar esta situação e promover um melhor bem estar, camundongos (Mus musculus foram expostos a duas condições: sem estímulos auditivos e com música clássica. Em todos os experimentos foi utilizada uma bateria de testes comportamentais. Os resultados demonstram uma diminuição significativa na imobilidade no nado forçado, aumento de entradas nos braços fechados do labirinto em cruz elevado e diminuição na imobilidade no campo aberto, nos animais que haviam sido pré-expostos anteriormente a 24h de música e sugerem que a música clássica causas mudanças na atividade motora em camundongos. Este estudo leva a conclusão que o enriquecimento do ambiente causa profundos efeitos sobre o comportamento de camundongos nos testes comportamentais e a música clássica é um método relativamente simples de contribuir para o bem estar de camundongos em cativeiro, mas pode comprometer resultados de experimentos como o nado forçado.

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)

Research was made on electronic NEDO research reports corresponding to the recent extending trend of Internet. The logical structure and electronic format of NEDO research reports as document were first studied considering document disclosure and reuse of technical information. HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

For the removal and recycle of CO2, a global warming gas, utilization of photosynthesis by micro algae is investigated. Formed micro algae are decomposed into CO2, H2O and CH4 again, which does not result in the permanent fixation. For the effective utilization of these micro algae, creation of petroleum alternate energy was tried through the co-liquefaction of micro algae with coal. Were investigated influences of the reaction temperature during the co-liquefaction and influences of catalysts, such as Fe(CO)5-S, Ru(CO)12, and Mo(CO)6-S, which are effective for the coal liquefaction. Micro algae, such as chlorella, spirulina, and littorale, and Yallourn brown coal were tested. It was found that co-liquefaction of micro algae with coal can be successfully proceeded under the same conditions as the liquefaction of coal. The oil yield obtained from the co-liquefaction in the presence of Fe(CO)5-S, an effective catalyst for coal liquefaction, agreed appropriately with the arithmetical mean value from separate liquefaction of coal and micro algae. It was suggested that pyrrhotite, an active species for coal liquefaction, was sufficiently formed by increasing the addition of sulfur. 2 refs., 7 figs., 1 tab.

This paper describes the technology development by which biomass is produced by treatment of pollutants using microalgae, and is recycled. A bioreactor system has been developed, in which microalgal biomass can be obtained through the effective treatment of CO2 and NOx using microalgae having ability of increase under the severe condition with simultaneous flow of CO2 and NOx. A new method has been also developed for separating and recovering the microalgae. Materials, such as glucose, glycerol, acetic acid, and lactic acid, were produced from the obtained biomass through physico-chemical and biological treatments. These materials can be converted into ethanol and hydrogen. For this treatment and recycling system, functions as a part of natural material recycling were considered to be most significant. Development of an analysis and evaluation method of an impact of this system on the natural environment is also tried. 1 fig.

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)

More than just repositories of knowledge, academics have an obligation to also forge new paths of discovery. As the boundary between what we know and what we still do not know expands, academics are not required to ask “what applied value does this discovery have.” Galileo’s curiosity in the time...... it took a chandelier to swing, measured only by his heartbeat, was not intended to help create modern timepieces, though it did through the discovery of the tautochrone nature of a pendulum. It was simple curiosity driven by unanswered questions and the human desire to know. We should pursue truth...

For the purpose of exploring accurately fracture groups greatly restricting the fluid flow of geothermal reservoirs, technical development was made for applying the elastic wave exploration technology such as the high precision reflection method, VSP, elastic wave tomography to the geothermal exploration. The Okiri area, Kagoshima prefecture was selected as a demonstrative field of a typical type where the steep and predominant fracture rules the geothermal reservoir, and experiments were conducted using the high precision reflection method and VSP. Fracture models were made, and the analysis results were studied by a survey using the array CSMT/MT method and by a comparison with existing data. Reformation of the underground receiving system used for VSP and elastic tomography is made for improvement of its viability, and was applied to the VSP experiment. The treatment/analysis system of the core analyzer was improved, and cores of the demonstrative field were analyzed/measured. Further, the exploration results, core analysis results and existing data were synthetically analyzed, and fracture models of the demonstrative field were constructed. Also, effectiveness and viability of the elastic wave use exploration method were studied. 90 refs., 418 figs., 24 tabs.

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.

Resumen Introducción La impulsividad es un rasgo de personalidad multidimensional relacionado con el control del comportamiento y las emociones. Está presente de manera diversa en los trastornos de la conducta alimentaria, particularmente, en la bulimia nerviosa (BN). Aunque la relación entre la impulsividad y BN ha sido objeto de numerosas investigaciones, en la actualidad se desconocen los sustratos neurobiológicos de esta relación. Objetivos Discutir críticamente la evidencia que sugiere que las alteraciones en los sistemas neuronales relacio-nados con las funciones ejecutivas, con la formación de preferencias y con la regulación de los estados emocionales sirven como base para el rasgo de personalidad impulsiva, así como su estado en subgrupos de pacientes con BN. Métodos Búsqueda selectiva de la literatura relevante. Resultados y conclusiones Esta discusión ilustra la complejidad de la relación entre la impulsividad y BN, donde la impulsividad actúa como un factor de vulnerabilidad que puede sensibilizar al sujeto con BN a estados emocionales negativos, durante los cuales modifica el impacto de estímulos internos y externos sobre el comportamiento y su regulación, favoreciendo así patrones de comportamiento maladaptativos e inflexibles.

Having the Mining Industry Restructuring Public Corporation located in the city of Katowice, Poland as the counterpart, a feasibility study has been executed on a project to utilize coal bed gas for power generation. Selected for the study are the 'Budryk coal mine' owned by KWK 'Budryk' Coal Company and the 'Pniowek coal mine' owned by Jastrzebie Coal Company. Since the Pniowek coal mine can utilize the whole quantity of recovered methane by 2001, the Budryk coal mine was selected as the object of the project. As a result of the trial calculation on the economy when the new gas power plant is installed in the Budryk coal mine, the energy substitution effect was found to equal to a power amount at transmission terminal of 6 MWh/year. Furthermore, when proliferation effect is taken into consideration, an enormous effect can be expected if new coal mines are developed and the existing cola mines will go further deeper, because the Silesian coal mine presently has the coal resource quantity of 57 billion tons and the annual gas discharge quantity of 750 million m{sup 3}. Therefore, if the technologies to recover, manage and utilize the gas are established at the Budryk coal mine, a large effect leading to an aspiration would be expected under the current situation of the structural reorganization under which the Polish coal companies are placed.

For the purpose of getting petroleum substitution energy and reducing greenhouse effect gas emission, an investigational study was carried out of the project for methane gas recovery/utilization at the Donbassa coal mine in Ukraine. At the Donbassa coal mine, degassing by test boring is being conducted to reduce the gas emission at coal face for safety, but most of the gas is discharged into the air. In this project, the following were studied: degassing boring/gas induction from bore hole/measurement in gas induction pipe, gas recovery system combined with gas induction in flyash, and installation/operation of gas engine power generation facilities (1,710kW x 7 units) with exhaust heat recovery boiler using the recovered methane gas as fuel. The results obtained were the petroleum substitution amount of 31,000 toe/y and the amount of greenhouse effect gas reduction of 480,000 t/y. In the economical estimation, the initial investment amount was 3 billion yen, the profitability of the total investment used was 2.9%, and the internal earning rate was 6.5%. (NEDO)

In this paper we consider the warped AdS3 black hole solution of topologically massive gravity with a negative cosmological constant, and we study the possibility that it acts as a particle accelerator by analyzing the energy in the center of mass (CM) frame of two colliding particles in the vicinity of its horizon, which is known as the Bañnados, Silk and West (BSW) process. Mainly, we show that the critical angular momentum (L_c) of the particle decreases when the warping parameter(ν ) increases. Also, we show that despite the particle with L_c being able to exist for certain values of the conserved energy outside the horizon, it will never reach the event horizon; therefore, the black hole cannot act as a particle accelerator with arbitrarily high CM energy on the event horizon. However, such a particle could also exist inside the outer horizon, with the BSW process being possible on the inner horizon. On the other hand, for the extremal warped AdS3 black hole, the particle with L_c and energy E could exist outside the event horizon and, the CM energy blows up on the event horizon if its conserved energy fulfills the condition E2>(ν 2+3)l2/3(ν ^{2-1)}, with the BSW process being possible.

Full Text Available A atrésia esofágica é a anomalia congénita mais comum do desenvolvimento do esófago, caracterizando-se por uma disrupção da sua continuidade, com uma prevalência de cerca de 1 em cada 2500 a 4500 nados vivos. A abordagem desta condição, desde o seu diagnóstico no período pré-natal até ao tratamento cirúrgico no período neonatal, constitui um importante desafio, tanto para o obstetra como para o cirurgião pediátrico. No âmbito do diagnóstico pré-natal, a ecografia, a ressonância magnética, bem como a análise bioquímica do líquido amniótico poderão ser úteis. Por outro lado, no que diz respeito ao tratamento cirúrgico desta condição, dispomos hoje de técnicas cirúrgicas minimamente invasivas, associadas a menor número de sequelas musculoesqueléticas, menor dor no pós-operatório e a um melhor resultado estético final. Neste artigo, os autores fazem uma revisão do papel das diferentes técnicas de diagnóstico pré-natal disponíveis, bem como das diferentes abordagens para o tratamento cirúrgico.

De la ecología de medios a la ecología profunda de medios: esclarecer la metáfora y visibilizar su impacto medioambiental

Full Text Available La ecología de medios ha generado una reflexión importante de la díada tecnología-sociedad. Sin embargo, a pesar de acuñar un concepto relacio-nado con el medio ambiente, diferentes autores han cuestionado que dicho campo multidisciplinario no haya derivado en ningún aporte importante relacionado con el contexto ambiental. Respecto de la ecología de medios, las tecnologías han causado un impacto definitivo sobre el planeta. No obs-tante, recientes tendencias en la investigación en comunicación conceptúan que este cambio trasciende lo simbólico y se instala en lo material con con-secuencias serias en los ecosistemas, en los seres vivos y en la sostenibilidad del planeta. Utilizando como base los planteamientos del filósofo norue-go Arne Naess, el presente artículo intenta contribuir a subsanar la deuda pendiente que tiene la ecología de medios con el contexto ambiental. Para propiciar esta reflexión, extendemos la metáfora de la ecología de medios a la ecología profunda de medios para a partir de este marco analizar la re-lación entre tecnologías y los aparatos/artefactos asociados a los medios y su relación con la sociedad.

The objectives are 1) development of biological processes needed for the treatment of pollutants and the conversion of resulting biomass to value added products such as energy and fine chemicals, and 2) development of techniques for monitoring of both biological and chemical hazards associated with process operation. We developed a microalgal system for simultaneous removal of CO{sub 2}/NO{sub x} from flue gas, as well as an electro-osmotic method for recovery of microalgal cells. A strategy for effective culturing of photoautotrophic cells in photobioreactors was also proposed. We utilized waste algal biomass to produce biosurfactants, and studied about structure-function relationship of lipopeptide biosurfactants. As an energy product, H{sub 2} was produced via lactic acid fermentation of algal biomass. Physiology of marine phytoplankton was also studied in relation to the future mass production of microalgal biomass. A rapid monitoring of microbial populations was possible by using fluorescent probes. An enzyme immunosorbent assay system specific to fish metallothionein was established for the assessment of aquatic environmental pollution. Human herpesvirus latent infection was effectively applied to biological assay of environmental hygiene. (NEDO)

The solar energy utilizing technologies having been developed under the Sunshine Project were used to have executed the international joint technology development on the 'solar heat utilizing drying system' in the Republic of Indonesia. This paper summarizes the achievements in fiscal 1998. In operating the pilot plant, three operational experiments out of seven experiments were carried out only by Indonesian engineers. As a result of the drying experiments, the heat collecting characteristics of the collector were as about half at 19 to 30% as the efficiency assumed in the design of 50%. The reason for this can be attributed to the fact that the cover glass used in the demonstration test in Japan had light permeability of about 87%, but the cover glass used in the test plant was made of frosted glass whose light permeability was about 37%. This glass is the only glass available for a heat collector in the solar heat hot water device in Indonesia, but is unsuitable for the heat collector. Another cause was that the insolation at the site was lower by about 30% than the one used at the design stage. (NEDO)

Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

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.

Remaining life assessment technologies for polymeric materials for geothermal power generation and methods for improving their heat resistance are reviewed, and concepts of scale-free technologies for FRP (fiber-reinforced plastic)-sandwiched pipelines for hot water transportation are described. Materials based on PTFE (polytetrafluoroethylene) and NBR (acrylonitrile-butadiene rubber) are chosen for use as DHM (down-hole motor) sealing material and for application to the stator. With PTFE as the matrix, four candidates are prepared, which are additive-free PTFE, and GF/PTFE, GF/CF/PTFE, CF/PTFE, each containing 20w% GF (glass fiber) and/or 20w% CF (carbon fiber). With NBR serving as the matrix, two candidates are prepared, which are NBR-A containing 20w% aramid fiber and NBR-W which is a vulcanized NBR-A. External force, heat, light, and mud are named as the degradation factors, and each factor and some combinations of external force, heat, and light are repeatedly imposed on the materials. During the effort to develop an apparatus for simulating geothermal circumstances in which the factors will affect the materials in complicated ways, a life assessment technique is developed for such polymeric materials. A technology is developed for providing polymeric rubber elastomer with a heat resistant feature. A study is made to replace transportation pipelines for injection wells with FRP sandwiched pipelines. (NEDO)

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.

This paper describes a pilot plant study on algae removal of a fluidized bed biofilm reactor system for lake water treatment. The system does not need backwashing because the fluidized bed suffers no clogging. Moreover, the system uses dissolved oxygen in influent water for aerobic biological treatment without aeration equipment. Thus, this system is a low energy and easy maintenance way to purify eutrophic lake water. The system was operated continuously at a flow rate of 1500 m{sup 3}/d{sup 1} for 9 months at Tsuchiura Port in Lake Kasumigaura. In this study, chlorophyll-a and dissolved oxygen in both influent and effluent water were monitored continuously. In summer (August to September) when water bloom occurred, the average removal efficiency of chlorophyll-a was 64% at the average influent chlorophyll-a concentration of 137.8 {mu}g/l{sup 1}. During the total experimental period (9 months), the average daily amount of removed chlorophyll-a was 40.3 g/d{sup 1} at the average influent chlorophyll-a concentration of 89.5 {mu}g/l{sup 1}. By analyzing the relationship between the removed chlorophyll-a and the consumption of dissolved oxygen, it was estimated that almost all of algae trapped in the reactor was degraded biologically. 20 refs., 12 figs., 2 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.

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.

As to high performance/high function plastic materials used in power generation facilities, technical trends were surveyed on the recycle situation and recycle R and D to study the subjects to be solved. For wire covering materials, vinyl chloride, polyethylene, rubber, etc. are used, and the recycle of resin has not been advanced. Concerning the generation of waste plastic, the existence of a lot of plastics different in characteristics makes the recycle difficult. As to the use of waste plastic as resource, the material recycle and recovery of combustion energy are being made, but only a part of the plastic is reused as chemical raw materials. Relating to the R and D of the chemical recycle technology, there are sample studies on the pyrolysis of polyolefine, dechlorination of chlorine base resins, etc. Recently, the following have been made public: proposal of depolymerization monomer based on the cyclic monomer, study of liquefaction of approximately 100% of the thermosetting resin, approach to the solvolysis by supercritical solvent.

Full Text Available La conciencia ha constituido uno de los principales problemas para las ciencias cognitivas. A un nive l epistemológico de la reflexión, esta dificultad est á dada en cómo se ha conceptualizado el problema, y las entidades conceptuales que constituyen el paradigma del procesamiento de la información, marco imperante del cognitivismo en la neurociencia cogni tiva y la psicología cognitiva. Pensar la concienci a como un producto de un proceso lógico-secuencial es un supuesto difícil de sostener dada la vasta evidencia actual de que el cerebro está en constant e actividad, con múltiples áreas que se activan de manera simultanea, y por otra parte en un organismo que si empre se encuentra en movimiento. Desde esta posici ón, proponemos la comprensión de la conciencia a partir de un análisis desde la filosofía budista, que es un riguroso estudio desde una perspectiva de primera p ersona. La psicología budista plantea a la concienc ia como un fenómeno interdependiente de causas y condi ciones y como un flujo dinámico, de momentos ligados en una relación de causalidad o karma . Este análisis que proveniente de las diferentes e xperiencias meditativas, con una enorme tradición, está relacio nado con los nuevos hallazgos de la neurociencia cognitiva y de la neurodinámica. Lo que nos plantea mos aquí, es proponer una reconceptualización preliminar que podría dar luces para un nuevo model o teórico para el estudio de los procesos conscientes.

The paper described the result of the fiscal 1996 development relating to hydrogen combustion turbines, as one of the hydrogen utilization technologies, which have excellent environmentality and are expected of remarkably high efficiency. In the film cooling system of first-stage moving/stationary blades, the smaller the pitch of film pore is, the higher the mean cooling efficiency becomes, indicating 0.7 at maximum. As compared with the conventional shower head type, the metal temperature can be reduced 30-40degC. In the recovery type inner (convection) cooling system, by reducing the blade number, the consumption amount of coolant can be reduced 6% in stationary blade and 13% in moving blade, as compared with the result of the preceding year. In the element test of the hybrid cooling system, film cooling efficiency was actually measured by the porous module test equipment, and the result well agreed with the calculation result. In the water cooling system, studied were water (stationary blade) and vapor (moving blade) of the closed cooling structure for realization of a cycle efficiency of 60%. In rotor/disk cooling, analyses were made of seal characteristic grasp tests and characteristics of the rotor. The effect of deflection in the mainstream was small. Besides, proper value of the seal overlapping amount could be obtained. 6 refs., 368 figs., 55 tabs.

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.

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.

To promote the introduction of methanol fuel into the thermal power plants, total assessment was provided. For calculating the methanol production cost, the plant was assumed to be constructed in the Southeast Asia or Middle East. Two methods, i.e., steam reforming and gaseous phase fluid methods, were investigated. Since the price of natural gas is low in the Middle East, the methanol production cost by the gaseous phase fluid method is estimated to be about 1.5 yen per thousand kcal. The transportation cost can be reduced into one-half to one-third of current cost using a large-scale tanker. Although the heating value of methanol per weight is lower than that of LNG, the volume flow of methanol is similar to that of LNG due to its low specific gravity. Conceptual designs were conducted for some power generation systems, such as gas turbine of combined cycle, diesel engine, and fuel cell. The power generation cost was estimated to be 8 to 9 yen per kWh, which depends on the receiving price of methanol. It is nearly equivalent to that of LNG combined cycle power generation. There are no problems of air pollution and ash disposal. When considering the long-term security of energy sources, the use of methanol would be one of the selections as utilization of natural gas. 6 refs., 33 figs., 25 tabs.

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.

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.

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.

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.

Full Text Available The relaxed posture of the eyelids keeps the eyes closed, the eyes open is part of the active behavior in living organisms, the activity gives rise to the blinking eye, that for the majority goes unnoticed. You can classify several types of eyeblink, blinking is a response that participates in the facial expression of the emotions. The muscle of the eyelid is essentially involved in emotional responses, as shown during the surprise, fear, or startle. We have studied the eyeblinking linked to aversive events of short duration. We need to know what is happening with the blinking eye to aversive stimuli with longer duration. The forced swimming test (PNF, stimulation provides a sharp, intense and prolonged by 15 minutes. Then we assess the response of eye blinking under the effect of the aversive stimulation provided by the PNF. We used 10 type Wistar male rats experimentally naive, with a weight next to the 300 g were housed with boxes-individual room and free access to food and water. The response of blinking eye was defined as: the behavior of closing and opening in a short period that the eyelids cover the eyes of the rat. We used a modified procedure of the PNF in establishing as a criterion of time 15 minutes for each of the two trials. The first assay began to put the rat in the cylinder with water. The second assay was performed 24 hours after the first assay. The sessions were videotaped, of which the recordings were obtained. The graph shows us a process of change in the blinkin eye, this suggests to us that this is a eyeblinking emotional, which passes through: the surprise; anxiety; and something like depression. It is a complex of processes in which they are involved a variety of mechanisms. We compare our results with other researches of blinking. The descriptors process involved in the anxiety-depression, are at different levels and can go from its link with physiological states until the mechanisms at the biochemical level responsible for that behavior.

The paper conducted the demonstration of the multiplier effect of 'the model project for heightening of the international energy consumption efficiency, etc.' carried out by NEDO and its subsidiary project, 'the project on the basic survey for promotion of Joint Implementation (JI),' and the comparative study between these projects and the JI/CDM projects proposed in the world. In the quantitative evaluation of the multiplier effect, in the case of making the demonstration of the same technology in the same area both in the model project and the basic survey for promotion of JI, it becomes possible to grasp the CO2 reduction effect with high accuracy, but the CO2 reducible amount is small. Inversely, as to the technology for which the basic survey for promotion of JI is studied, but the model project is not carried out, it becomes possible to grasp the CO2 reduction effect with low accuracy, the CO2 reducible amount is large. In the comparison with the JI/CDM projects proposed in the world, the CO2 reduction amount was approximately $2.7 billion, 250 million tons, in the UNFCCC project, and approximately $5.0 billion, 500 million tons, in the IJ project. There was no very big difference in the cost effect. (NEDO)

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.

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.

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.

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.

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.

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

The present research and development is intended to establish the fundamental technologies required to develop a pilot plant, by investigating development of such major component devices as turbine blades and rotors in a hydrogen combustion turbine. In the turbine moving and stator blade cooling technology, it is intended to achieve the power plant efficiency of 60% (based on HHV) as established in the interim evaluation performed in fiscal 1996. Therefore, the necessary element tests, detailed blade design, and partial fabrication were moved forward on the three kinds of the selected blade cooling systems as the cooling systems that can deal with the steam temperature condition as high as 1,700 degrees C. Fiscal 1998 will execute the design and fabrication of test blades and testing devices for blade cooling evaluation tests to be performed at Tashiro Township in Akita Prefecture. At the same time, evaluation and selection will be made on the three kinds of the cooling blades. In the rotor cooling technology, for the purpose of analyzing the rolling-in phenomenon of steam in the main turbine flow, a method will be developed to analyze rotor disk cavity temperatures based on CFD, the basic sealing conditions based thereon will be discussed, and generalization will be made on the rotor cooling technology.

I feel that the changes which have taken place in science in the last few years open up new possibilities, about which I should like to say a few words. In 1951 we began work on thermonuclear reactions in the confident belief that we would solve the problem with a rush and immediately. I was assigned the task of ensuring that our future thermonuclear reactor would not get too much out of hand. It was like the story of the man who wished to invent a perpetual motion machine and had taken out a patent on a method for keeping it under control. This attitude stemmed from the successes in developing ''explosive thermonuclear reactors'', a task which was achieved within a very short period of time, leaving physicists with the impression that they could do everything - and do it fast. However, experience soon showed that here we had a scientific rather than a technological problem and that it would be necessary to study in detail the physics of plasmas - which we have now been doing for over ten years. [Russian] Mne kazhetsja, chto za poslednie gody- v nauke proizoshli izmenenija, otkryvshie novye vozmozhnosti, na kotoryh ja hotel by ostanovit'sja.

Mne bylo porucheno obespechivat' regulirovanie budushhego termojadernogo reaktora, chtoby tot ne ochen' ''razognalsja'' i ne vyshel iz-pod kontrolja.

Bol'shie uspehi v razrabotke ''vzryvchatyh termojadernyh reaktorov'', kotorye byli sozdany za ochen' korotkoe vremja, porodili u fizikov uverennost' v to, chto oni mogut sdelat' vse i sdelat' bystro.

The whole amount of hydrogen consumption for chemical industries all over the world is estimated to be 249.7 billion Nm{sup 3} in 1974, while 367.2 billion Nm{sup 3} in 1980 roughly under a bold assumption, based on 3 current big consumption fields of ammonia production, methanol production and petroleum refining, and some promising fields in the future such as reduced iron and synthetic protein. Consumption ratios for every field are probably 54.9% in ammonia production, 30% in petroleum refining, 9.5% in methanol production and 5.6% in others in 1974, and nearly similar in 1980. However, although there are various troubles, if a large amount of methanol is used as fuel in the future, and its production plan is promoted to satisfy the demand of methanol fuel, hydrogen consumption for methanol production will increase drastically. In the future, if the production process of hydrogen as secondary fuel is established, such hydrogen also will be used for various chemical industries naturally. Research was thus made on use of oxygen as byproduct inevitably. (NEDO)

The paper conducted the demonstration of the multiplier effect of 'the model project for heightening of the international energy consumption efficiency, etc.' carried out by NEDO and its subsidiary project, 'the project on the basic survey for promotion of Joint Implementation (JI),' and the comparative study between these projects and the JI/CDM projects proposed in the world. In the quantitative evaluation of the multiplier effect, in the case of making the demonstration of the same technology in the same area both in the model project and the basic survey for promotion of JI, it becomes possible to grasp the CO2 reduction effect with high accuracy, but the CO2 reducible amount is small. Inversely, as to the technology for which the basic survey for promotion of JI is studied, but the model project is not carried out, it becomes possible to grasp the CO2 reduction effect with low accuracy, the CO2 reducible amount is large. In the comparison with the JI/CDM projects proposed in the world, the CO2 reduction amount was approximately $2.7 billion, 250 million tons, in the UNFCCC project, and approximately $5.0 billion, 500 million tons, in the IJ project. There was no very big difference in the cost effect. (NEDO)

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)

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

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.

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.

Described herein are the FY 1998 results of the activities for development of extraction and production technologies for the deep-seated geothermal resources, which are expected to contribute to increased geothermal power generation capacity. The program for the PTSD logging technology connects the S probe to PT probe, to simultaneously measure temperature, pressure and volumetric flow, producing the data of good quality even in a high temperature environment over 327 degrees C. Thus, possibility of the commercial system is confirmed. The D probe also produces a density calibration curve showing very good linearity, and operates normally in a high temperature environment of 406 degrees C. The program for the PTC monitoring technology conducts the field tests at Larderello, Italy, to confirm the sampler functions in a high temperature environment. The program for the tracer monitoring technology extracts promising tracers stable at high temperature from those for the liquid, vapor and liquid/vapor mixed phases. Silica is observed to be massively dissolved at 400 to 1,000mg/kg in the fluid under deep geothermal conditions. Scale precipitation rate is minimal for the first 21 days, but increases linearly with time thereafter. The experiments are also conducted for formation and prevention of the Fe-Si-based scales during the flushing period. (NEDO)

Technological development has been made on excavation of geothermal wells, which are dense, hard, and high in temperature and pressure, in developing geothermal resources in great depths. This paper summarizes the achievements in fiscal 1999. This fiscal year has performed the excavation test using an actual well to verify the reliability in practical use of the developed heat-resistant and durable bit. The test was executed by using a bit with a diameter of 8-1/2 inches in a ground bet having a maximum temperature of 300 degrees C in the Yamakawa geothermal field. As a result, good site evaluation was obtained that the wear and tear after lift-up showed no problems, and sufficient performance was verified in the drilling rate and durability. In addition, the low specific gravity cement for high temperature use that has been newly developed was given a cement mixing test to identify its workability at site and hardening properties, at a test well with a temperature of about 40 degrees C in the Okiri geothermal field. The actual well test was performed in a large-scale lost water occurred in a return well during an excavation by Nittestu-Kagoshima Geothermal Company. Effects were recognized in measures to prevent water loss. (NEDO)

Bioconsortia are microbial composites composing of more than two kinds of microorganisms with special functions. To utilize their advanced functions, some techniques have been developed for analyzing their functions and interactions, and for identification, separation and incubation of the constituent microbial groups. In FY 1997, an investigation was made on technology trends, domestic researchers, and research topics related to bioconsortia. To manage and promote the progress of research at the National Institute of Bioscience and Human-Technology where the centralized management of this project is conducted, meetings are held once a month to examine the progress at the institute, in which reports are made and discussions are held on how each research item is progressing. In addition, meetings of the committee to promote research are held every other month to consider and examine measures required for promoting the research. Re-entrustment of research has been made on two subjects, i.e., `Studies on biological significance of symbiotic microorganisms` by Prof. Ishikawa of the University of Tokyo, and `Study on the relationship between the biosynthesis of useful terpenic materials of plant origin and the differentiation of plant tissues, and their effective production by plant cell cultures` by Prof. Inoue of Gifu Pharmaceutical University. 27 refs., 13 figs., 1 tab.

For the purpose of reducing the CO2 emitted from electricity/vapor supply facilities of Bataan Refinery in the Philippines, study was conducted of optimum energy supply facilities considering the effective use of the oil residue and future reinforcement of the refinery. Concerning the high-pressure/high-temperature condensing extraction boiler/turbine cogeneration, gas turbine cogeneration and low speed diesel engine cogeneration, comparative study was carried out in terms of thermal efficiency, reliability/preservation, environmental acceptability, effectiveness of measures for the future excessive oil residue, etc. As a result, the study was concluded as follows: the electric power consumption will markedly increase in the future; however, in the light of the situation of the refinery where the vapor demand will not increase, it is the most suitable to use low speed diesel engine cogeneration facilities as on-site power generation facilities which can burn the excessively increasing oil residue as direct fuel. The CO2 reduction effect estimated from the project on the present scale was 132,880 t-CO2/y, and the energy conservation effect estimated was 50,861 toe/y. (NEDO)

For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

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

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

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.

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.

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.

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.

Specific growth rate ({mu}) and generation time (t{sub d}) of the flagellate were 4.6 day{sup -1} and 3.5 h{sup -1}, respectively at 20degC and 30degC, whereas in the case of 10degC the lag values of {mu} and t{sub d} were obtained by 1.9 fold in comparison with the removal ratio of 61% at the first cultivation day and that of 99% at the 2nd day at 30degC, while at 20degC the removal was only about 30% in the first day, but P. tenue could be perfectly reduced at the 2nd day. Although the reduction rate of the P. tenue was slow at the lower temperature of 10degC, the removal reached 98% in the 7th day. Removal rate of P. tenue by the flagellate increased with the increase in temperature and reached the maximal value with 4.0 h{sup -1} at 30degC. The flagellate could contribute to the degradation of MIB, although the degradation was lower than that of P. tenue. It was found that the microflagellate could favorably predate on P. tenue and degrade its metabolite, MIB emitting musty odor in a wide range of temperature. 27 refs., 8 figs., 3 tabs.

Described herein are the results of the FY1994 research program for advanced glazing in which solar energy is efficiently utilized. The peripheral techniques are surveyed for evaluation of characteristics of large-size dimming glass, optimization of film compositions and scaling up. The dimming device, made on a trial basis, attains a target controllable rage of at least 50% for visible light transmittance. The suitable components include WO3 as the electrochromic material producing color under a reducing atmosphere, NiO as the counter electrode producing color under an oxidative atmosphere, and hydrated SbOx as the proton-conducting electrolyte. The test results indicate possibility of the dimming glass stably operable while being irradiated with a quantity of sun ray of around 10 years. The study on scaling up the dimmer glass develops, on a trial basis, a process for producing large-size glass and evaluates its characteristics, where the film parameters are investigated. It also investigates the peripheral techniques for assembling the devices for the large-size glass, and develops useful techniques, such as those for sealants and improved sealing methods. 1 fig., 1 tab.

Feasibility of joint implementation promotion through plant-related technology transfer is investigated for 15 Central and Eastern European countries. Emissions of the greenhouse effect gases can be relatively easily abated in these countries by improving energy utilization efficiency, because they have more advanced infrastructures than developing countries, and are behind the developed countries in modernization of the facilities. Therefore, European and North American countries have been positively promoting the AIJ programs in these countries, and there are fierce competitions for promising projects. It will be necessary for Japan to provide public loans, e.g., environmental yen loans, to promote the plant-related JI/CDM projects in these countries. Many of these countries have not drawn plans for reducing emissions of the greenhouse effect gases, and expect establishment of the international cooperation systems for exchanging information related to global warming problems, and introducing the Japanese technologies and policies.

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

The trend of technology is surveyed from a standpoint that, in the process of CO2 fixation using microbes for the production of useful substances, it is essential, in view of income/outgo balance and economy, to utilize their catalytic function. The survey centers about the feasibility of the utilization of organic wastes, cellulose wastes in particular, as an energy source. Special attention is paid to the energy of artificial light and laser beams. From a point of view that it is important to suppress cell multiplication and to effectively utilize only catalytic activity for the production of useful substances, the cell division mechanism of the Corynebacterium is analyzed, and the findings are compiled to facilitate the study as to whether the division may be controlled. A report is also prepared on the metabolic mechanism of a photosynthesizing bacterium that is judged to be the most promising species. Reference is made to aerobic and anaerobic bacteria. Shown are the organic compounds that are formed by CO2 gas fixation thanks to microbial or enzymatic reactions. To emphasize their importance as an energy source and to explain the conversion of biomass into useful substances, the technology and economy of conversion into fuel compounds are surveyed. The production of ethanol out of organic wastes is evaluated in the way of LCA (life cycle assessment). (NEDO)

For planning the Pacific area energy policy of Japan, the field survey on energy situations was carried out in Laos and Myanmar. Since Laos is rich in hydraulic resources, the future electric power development is expected. Development of oil and coal resources is yet in a planning stage. Electricite du Laos (EdL) is in charge of electricity business, and its power generation capacity amounts to 220MW (including hydroelectric one of 93%), and a half of it is exported. Based on the predicted growth rate of 9%/y for domestic power demand, development of the capacity to 440MW by fiscal 2002 is scheduled. Myanmar has natural gas and various mineral resources, and is rich in hydroelectric resources. Myanmar Electric Power Enterprise (MEPE) is in charge of electricity business. The power generation capacity amounts to 1.34GW (including private one of 26%). The power generation facility is composed of gas turbine one of 53% and hydroelectric one of 33%. Based on the predicted growth rate of 11.5%/y for domestic power demand, development of the capacity to 1.6GW by 2001 is scheduled. For the present, conversion of previous gas-firing power plants to efficient combined cycle ones is a main issue. 21 figs., 43 tabs.

A large quantity of waste sea water, exhausted after having been used as cooling water in the thermal and unclear power stations, is higher by about 7 centigrade in temperature than that when taken in. Its utilization to the marine cultivation to increase product was explained in present status and points of problem. Among aquatic animals to like high temperature, those, valuavle from the viewpoint of fishery, are bred in different places. Upon breeding spawn to fry young fish, there are two methods of using it, ie., as species to be cultivated or let go in the water flow, and for the production of edible fish, high in price, such as sea bream, yellowtail and lobster. In any case, hot exhaust water gives effect of having fish quickly grow, and stimulating spawn and fry young fish in sexual ripeness. For example, ear shell and prawn are 5 to 6 times in elongation of shell length and 9 times even in weight, respectively, as large as those in case of natural sea water. While there are problems in costing required for pumping hot exhaust water up in the cultivation on land, and temperature adjustment in summer and winter, and water quality control in the crawl cultivation at the water takeout, which must be going to be solved for the commercialization and industrialization. 10 figs., 1 tab.

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)

Performance of a solar heating system with a hydrothermal source heat pump was evaluated and compared with that of a direct solar heating system. The sun-dependency rates ({Sigma}D and {Sigma}H)of the direct system and heat pump (HP)-provided system were expressed as a function of the rate ({alpha}) of the auxiliary heat against the collected heat and as a function of the performance coefficient and {alpha}, respectively. When the sun-dependency rates are compared, it is found that the HP-provided system is the more advantageous when {Sigma}H/{Sigma}D>1. The relationship between the {alpha}`s of the two systems was clarified and computation was performed to compare the sun-dependency rates on condition that the two are equal in the heat collecting area. Although the sun-dependence rate cannot be elevated to 100% in the HP-provided system, it achieves a sun-dependency rate higher than that of the direct system even when the heat collecting area is small. In cases where the building is economically limited, for instance, with respect to the area for solar collector installation, it is advantageous to employ the HP-provided system. 5 figs., 1 tab.

It is decided in the COP4 that the concrete schemes for the (Kyoto Mechanism) should be boiled down towards the end of 2000. Of the many outstanding issues concerned, those related to the clean development mechanism (CDM) involve a number of problems awaiting solution. In particular, setting the baselines for amounts of the greenhouse effect gas emissions in projects not existing, which are essential for identifying reduced amounts of emissions (or credits), poses serious difficulty because of wide arbitrariness involved in the methodology. Therefore, (standardization) of the procedures is demanded for the accurate identification. In actuality, however, no methodology has been established as to what methods will be possibly applicable to widely diversified types of projects. This workshop, therefore, has focused the discussions on the (baseline problems), expecting to serve as a trigger for the future directions by presenting international researches and promoting the discussions thereon to deepen recognition of these problems, where the AIJ experiences have served as one of the bases.

This paper describes development of a technology to decompose dioxins in incineration fly ash. Experiments were carried out during fiscal 1998 by using a bench-scale plant and a laboratory-scale plant of the installed supercritical water treatment equipment designed and fabricated in fiscal 1997. With the bench-scale plant, operation methods were discussed, whereas high temperature and pressure operation of 25 MPa and a temperature internal to the reactor of 350 degrees C were achieved. An alcohol combustion test and a preliminary slurry delivery test were also performed. With the laboratory-scale plant, operating methods were discussed, and combustion tests were carried out by using different organic matters as fuels for the supercritical water oxidation reactor. Investigations were executed on the effects of reactive operation parameters on organic matter decomposition rates, produced gas compositions, and reactor wall temperatures. The intensity of hydrogen bond between solvent and water has decreased to almost half of the normal temperature and pressure water in the vicinity of the critical point. However, strong interaction still remained in terms of per unit density. A portable equipment (650 degrees C and 25 MPa at the maximum, and standard treatment quantity of dry fly ash of 1 kg/h) was operated for demonstration. Operation methods and organic matter decomposition characteristics were identified in alcohol operation and slurry operation. (NEDO)

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.

This paper reports on the present situation of the chemical use of hydrogen and oxygen, and the short-term, medium-term, and long-term forecast. The main usage of hydrogen is ammonia synthesis, petroleum refining, and methanol synthesis. In the usage of these three, there are factors of structural changes now and in future, and it is extremely difficult to predict the amount in a short term up to around 1980. In a medium term prediction, from the result of predicting the demand of ammonia, methanol and hydrodesulfurization, the total 1985 hydrogen demand is estimated at approximately 60 billion Nm{sup 3}, and approximately 67 billion Nm{sup 3} as the gross hydrogen demand. Further, judging from that synthetic protein, fuel use methanol, and reduced iron are estimated to reach a certain production size in and after 1985, new demand for hydrogen is expected to be approximately 100 billion Nm{sup 3} mostly including fuel use methanol. In a long term prediction, it is extremely hard to predict the demand because of various factors existing in Japan and abroad. As predicted in a medium term, the amount of chemical use of hydrogen is expected to increase more and more, even if calculating it only in the field of ammonia synthesis, petroleum refining, and methanol synthesis.

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.

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.

In fiscal 1974, analysis was made on the concept design of solar furnace hardware, and utilization and use purpose of solar furnaces as high-temperature industrial heat source. Detailed survey was also made on the history of high- temperature solar furnaces. Based on the history of large- scale solar furnaces and the current state of some industries consuming a large amount of thermal energy, wide consideration was made on the applicability of large-scale solar furnaces as heat source in the future. 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)

Studies have been made about a heat accumulation tank type cooling system making use of radiation cooling that is a kind of natural energy. The daily operating cycle of the cooling system is described below. A heat pump air conditioner performs cooling during the daytime and the exhaust heat is stored in a latent heat accumulation tank; the heat is then used for the bath and tapwater in the evening; at night radiation cooling is utilized to remove the heat remnant in the tank for the solidification of the phase change material (PCM); the solidified PCM serves as the cold heat source for the heat pump air conditioner to perform cooling. The new system decelerates urban area warming because it emits the cooler-generated waste heat not into the atmosphere but into space taking advantage of radiation cooling. Again, the cooler-generated waste heat may be utilized for energy saving and power levelling. For the examination of nighttime radiation cooling characteristics, CaCl2-5H2O and Na2HPO4-12H2O were tested as the PCM. Water was used as the heating medium. In the case of a PCM high in latent heat capacity, some work has to be done for insuring sufficient heat exchange for it by, for instance, rendering the flow rate low. The coefficient of performance of the system discussed here is three times higher than that of the air-cooled type heat pump system. 8 refs., 5 figs., 4 tabs.

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.

Survey was made on application technologies of next- generation high-density energy beams. For real application of laser power, application to not exciting source of YAG crystal but machining directly is highly efficient. For generation of semiconductor laser high-power coherent beam, phase synchronization and summing are large technological walls. Short pulse, high intensity and high repeatability are also important. Since ultra-short pulse laser ends before heat transfer to the periphery, it is suitable for precise machining, in particular, ultra-fine machining. To use beam sources as tool for production process, development of transmission, focusing and control technologies, and optical fiber and device is indispensable. Applicable fields are as follows: machining (more than pico seconds), surface modification (modification and functionalization of tribo- materials and biocompatible materials), complex machining, fabrication of quantum functional structured materials (thin film, ultra-fine particle), agriculture, ultra-precise measurement, non-destructive measurement, and coherent chemistry in chemical and environment fields.

This paper describes comprehensive discussion on hydrogen utilizing subsystems. Hydrogen combustion is characterized by how low the ignition energy is, and how fast the flame propagates. In addition, flame stability is high also in diffusion combustion. However, the diffusion combustion produces a great amount of NOx, the amount varying depending on the degree of air pre-mixture. Since it causes reverse ignition very easily in the pre-mixture degree corresponding to low NOx zone, development of a burner with drastically new mechanism is demanded. In hydrogen fuel cells, the ratio of hydrogen fuel cost accounting for in the power generation cost is very high. As an automobile fuel, very much leaner combustion is possible than in conventional internal combustion engines, and ignition energy is small. However, such abnormal combustion as reverse ignition and early ignition may occur, and their prevention is an important assignment. Issues in aircraft engines are verification of safety, and cost of liquefied hydrogen. Steam turbines have reached their limit already, but gas turbines are expected of exciting efficiency improvement. This paper describes prospects on chemical utilization of hydrogen in the existing fields and new fields. (NEDO)

Full Text Available Los repetidos episodios de contaminación de aguas superficiales y subterráneas origi­nados por herbicidas utilizados en el cultivo del olivar son motivo de una gran preocupa­ción en muchas regiones mediterráneas. El hecho de que la mayoría de las formulacio­nes comerciales de herbicidas contengan las materias activas en una forma inmediata­mente disponible acentúa el riesgo de pérdi­das por transporte de los herbicidas que se aplican al olivar y, por consiguiente, el ries­go de contaminación de aguas adyacentes. En este trabajo se presenta la preparación de formulaciones de liberación lenta de tres herbicidas (diurón, terbutilazina y MCPA, muy utilizados en el control de malas hier­bas en el olivar, a partir del soporte de los mismos en una montmorillonita modificada con cationes hexadeciltrimetilamonio. Pos­teriormente, se ha evaluado la capacidad de las formulaciones preparadas de reducir la velocidad de liberación de los herbicidas en medio acuoso y de retrasar su lixiviación a través de columnas de suelo, en compara­ción a formulaciones comerciales conven­cionales de los herbicidas. Los resultados sugieren la utilidad de las formulaciones desarrolladas para reducir las pérdidas por transporte de los herbicidas estudiados tras su aplicación a suelos de olivar.Ground and surface water contamination by herbicides commonly applied to olive groves is a matter of current concern in Mediterranean regions.

The conceptual model and feasibility of the hybrid energy system for residences and public facilities in snowy cold regions were studied. Based on the existing data, the existing and available amounts of natural energy and unused energy in the target area, Sapporo were estimated. Based on the predicted energy demands of 4 kinds of building models, the energy systems for such models were studied. The use of the following energies was considered: photovoltaic power generation and solar heat for all the models, household sewage energy for the multiple-dwelling house model, and wind power generation for the public facility model. The annual energy balance was calculated to evaluate it. The use of additional commercial electricity was necessary, while surplus solar heat energy was found in summer which can push up the self-sufficiency rates of the residence and public facility models to 70% and 44%, respectively. The multiple- dwelling house model which can use a large amount of household sewage energy could utilize 80% of new energy, while the other 3 models utilized only 60-70% of that. 81 figs., 42 tabs.

In the estimation of wind power output, good agreement with the results estimated was confirmed at points very near to posts of observation of wind characteristics. As to the evaluation of effects of wind power generation to the system, power system frequencies were simulated using the models constructed and using capacity and kinds of frequency adjusted power source as parameter. As a result, it was indicated that there was a possibility of frequency's sharply fluctuating in case the surplus energy in frequency adjustment is reduced by fluctuations in demand and further in case wind power output is fluctuated.

This project aims at development, demonstration and utilization of waste recycling technologies. This report summarizes the fiscal 1998 results. The test/demonstration plant for separation and removal of foreign materials was constructed for effective use of waste building wood, and its optimum operation condition was studied. Although some foreign materials exists, 90% of waste building wood chips were separated and recovered through some improvements for the plant. An advanced separation technology is expected. As for fibering technology, fibers with target compression strength were obtained from cedar chips through a disintegration experiment using a newly developed refiner plate. Although the compression strength of fibers obtained from waste building wood chips was slightly poor, it is attained by increasing the target specific gravity of light- weight wooden materials by nearly 10% from 0.1. As for fiber orientation technology, as the tension of a forming belt was adjusted to achieve sufficient width compression, nearly 90% of the target compression strength was attained. A width compression method remains to be solved. (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.

Polders have no basin of their own, and the supply of irrigation water in polders is always short and unstable. The irrigation water system is so structured that the conflicting objects of both the insurance of irrigation water and drainage of rainwater can be achieved. Quoting an example at the surrounding area of the Kojima Bay in the southern area of Okayaja Prefecture where inning (land reclamation by drainage) has been practiced for a long time, problems in drainage improvement required for better use of low-lying flat lands are discussed. There are complicate relations among the safety against flood, rainwater drainage capability, stock capacity, and critical leveling time, therefore, the basic operation which must be performed at first in making a drainage plan is to determine the basic framework of the plan taking those relations into consideration. In low-lying flat lands, safety of the total area against flood has been established basing on the stock capacity of the paddy fields, and it is important to secure paddy field areas to a certain extent. 8 refs., 7 figs., 1 tab.

The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

A simplified method is developed, which measures dioxins in flue gas without using GC/MS (gas chromatography/mass spectrometry) of the double focusing type. The sampling device is built of two collecting bottles, containing water and diethylene glycol, and uses no XAD-2 (cross-linked amberlight divinyl benzene) resin. Such a design does not need time consuming Soxlet extraction in the sampling process and shortens the processing time. An HPLC (high performance liquid chromatography) system replaces the convenient column chromatography system in the cleanup process, and this enables automation and rapid treatment. For the measurement of toxicity equivalent, GC/MS is used to separate and quantify 17 kinds of toxic isomers as in the conventional method. The GC/MS is of the quadruple focusing type, however, and this reduces the device cost at the initial stage and shortens the time for operators to acquire the skills of maintenance and operation. Though the quadruple focusing type is inferior to the double focusing type in sensitivity, the shortcoming is compensated for by massive specimen injection using a PTV (programmable temperature vaporizer). The result of a JIS (Japanese Industrial Standard) method and the result of this newly developed method are found to agree excellently with each other. This method is simple and efficient, suitable for use in the analysis of small incinerator flue gas. (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.

In the study of enhancing the desulfurization rate in gas oil deep hydrodesulfurization process, it was found that NiHY zeolite having Ni introduced by using the ion exchange method shows stable activity, whereas the target of sulfur content of 50 ppm or lower was achieved by adding the third constituent and by optimizing the impregnation solution to pH3. In the study of the Ni, Mo/alumina catalyst, the desulfurization activity was enhanced by optimization of carrier pore size to 120 to 140 angstroms and by addition of phosphorus and silica, having the target of sulfur content of 50 ppm or lower achieved. In the research of manufacturing low-sulfur light oil using heavy oil desulfurization and hydrocracking, optimization was performed on the catalyst used in the latter stage of heavy oil desulfurization, and evaluation was given on the performance in combination of commercially available hydrometallation catalyst/middle part HDS catalyst/bottom part HDS catalyst. As a result, achievement of the target of sulfur content in the desulfurized light oil of 300 ppm or lower was verified. Life evaluation test is in continuation on the heavy oil hydrocracking catalyst. (NEDO)

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.

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)

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.

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.

A survey was conducted of various systems which use in summer cold heat from the snow stored in winter. A model of the cold accumulated heat system of the type which has a high possibility of the introduction was built to study a possibility of the realization. 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.

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.

The current most important solar energy utilization fields are solar energy power generation (solar heat and photovoltaic power generation), and solar heat cooling and heating. A solar heat power system collects or stores solar thermal energy as energy source of power systems, and converts it to electric power through heat exchange systems. To establish such system, not only R and D on a collector, absorption capsule, storage unit and heat transfer unit, but also complete study on an optimum system configuration and environmental impact are necessary. A photovoltaic power system converts solar energy to electric power directly by photoelectric conversion device such solar cell. Except specific local uses, drastic cost reduction and improvement of a conversion efficiency (at present 12-15%) and life (several years) are necessary for solar cells. Although a lot of solar heat cooling and heating systems is in practical use in Japan, for its further diffusion an important research task is development of heat collector excellent in efficiency, cost, life and maintainability.

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.

A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs., 4 tabs.

For prevention of global warming by greenhouse effect gas, study was made on energy saving measures for Achinsk refinery in Russia. Achinsk refinery is a relatively new plant put into operation in 1983, however, because of no various equipment for use combustion heat effectively, its average thermal efficiency is as low as 60%-70%, resulting in fuel consumption more than necessary one. Based on the study result, the following remodeling designs were made: Improvement of a heat exchange efficiency by relocation of heat exchangers to reduce fuel consumption of a heating furnace as much as possible, conversion of an existing heating furnace based on an old design concept to an advanced one, installation of a waste heat recovery system including a preheating convection unit and air preheater, reinforcement of heating furnace wall insulator, installation of an optimum control system for furnace operation, and improvement of a fuel supply system efficiency. This design showed possible reduction of heating furnace load, and possible furnace thermal efficiency of 90%. (NEDO)

This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method. The remaining life of transformers is determined by how seriously the coil insulating paper has been deteriorated, and furfural in the oil was found effective for the parameters. Particularly, application of the NN was revealed to be effective in estimating electric motor deterioration. A high-temperature sulfide corrosion rate estimating model was developed from the operation and measurement data of the facilities by applying the NN and TCBM. (NEDO)

Field survey was made on the current state of and issues on energy in Vietnam. In Vietnam, firewood is in wide use as non-commercial energy, and sums to a half of total energy consumption. Other energies such as hydroelectric power, petroleum, natural gas and coal are self-sustainable. Commercial energy consumption in 1995 is estimated at 10,070,000t in oil equivalent, which is broken down into 23% for coal, 42% in oil, 5% for natural gas and 30% for electricity. Abundant water resources will form the mainstay of future electric power supply. Commercial production of oil started in 1986 becoming an oil exporting country. Several promising natural gas fields were discovered as the result of the exploration by foreign capital. Coal deposits are estimated to be nearly 3.5 billion tons, and most of them are anthracite. Electric power demand is growing at a higher rate than the economic growth of Vietnam. The growth rate of electric power demand is set to be 1.3 times that of GDP. Since construction funds for new plants cannot be satisfied with the national budget and domestic investment alone, the country is expecting foreign capitals. 21 figs., 36 tabs.

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)

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 effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known.

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)

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

To promote the development of deep-seated geothermal resources in a rationalized way, studies are conducted about deep-seated geothermal resource assessment techniques, development guidelines, and the like. Data were collected at the Sumikawa-Onuma district, Ogiri district, Mori district, Yanaizu-Nishiyama district, and the Onikobe district, and compiled into a database to be open to the public. Studies were made about methods for estimating parameters for deep-seated geothermal reservoirs. The resultant findings indicate that, in the Uenotai and Sumikawa-Onuma districts where geothermal reservoirs are governed mainly by a fracture network, the relaxation method and extrapolation will be effective for deep-seated reservoir temperature estimation, and the ascending current analysis method and extrapolation for permeability estimation. The findings also indicate that the expanse of deep-seated reservoirs will be suitably estimated using a method similar to that applied to shallow-seated reservoirs. In the study of the estimation of the amount of deep-seated geothermal resources, it is concluded that the simplified model A will be effective in dealing with a geothermal district where there is a well-developed fracture network and the simplified model B in dealing with a geothermal district where supply of deep-seated fluid governed by an extensive fault prevails.

Currently, although prevention of fluidization of asphalt using modified asphalt mixed with resin and rubber has been taken, application of such a fluidization prevention means is limited, due to the reasons of high cost and difficult quality control, particularly mainly to places in the vicinity of intersections where the traffic is heavy, on bridges and in tunnels where construction is difficult. In addition, although low penetration asphalt is used, in this case, there are problems of deterioration of wear resistance and of cracks caused by temperature stress at low temperatures. The writers have conducted a study of imparting asphalt a fluidization resistance by adsorbing light oil in asphalt on a coal-ash fluidization preventing agent (FB) mixed in advance in an asphalt mixture. This article reports a study about the influence of mixing ratio and grain size of coal-ash upon the anti-fluidization property and durability of asphalt when coal-ash discharged from coal thermal power plants is mixed into asphalt, and a confirmation of the effectiveness of the mixing of coal-ash by actual road tests. 6 refs., 22 figs., 11 tabs.

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)

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)

Information was collected and surveys were conducted in Mongolia in an effort to acquire information necessary for energy related technical cooperation. The results were arranged in four fields which are (1) the current state of economy and the future trend, (2) current state of energy production/consumption and the future trend, (3) current state of power supply/demand and power facilities and the future trend, and (4) the current state of energy efficiency enhancement and the future trend. Mongolia has a population of 2.45 million at a density of 1.57/km{sup 2}, with Ulan Bator the capital inhabited by 0.69-million people. The mean air temperature is -10 degrees C in the period November through March, which makes heating indispensable. Power stations are of the heat and power cogeneration type. Power is supplied by the Eastern, Central, and Western systems, with the Central system producing 80% or more and independent power sources 10%. Its economy has already recovered from the confusion that followed the change of its national constitution. Mongolia's demand for power lingers low, however, and its facilities can produce more electricity than what is now wanted. Energy efficiency enhancing activities should start with the upgrading, reinforcement, and maintenance of the existing facilities and with independent power sources. (NEDO)

Japan-China joint coal survey was made through seismic prospecting by Japanese group and drilling prospecting by Chinese group. Mei-Xian mine property includes coal seams of the Jurassic period, and is covered with the quaternary period stratum without any coal seam. The base of the quaternary period stratum exists at depth of 50-400m, while the coal seams at depth of 300-700m. Among 11 existing seams, the 1st and 5th seams are main objects for prospecting. The 5th seam of 0.2-8.96m (2.95m in average) thick is the most expected important one, distributing all over the mine property. The 5th seam also has branch seams spreading over 2.5km from east to west and 1.2km from south to north in the center part of the mine property. The 1st seam of 0-8.62m (2.90m in average) thick is most thick in the south part of the mine property. The theoretical amount of coal deposits in the whole coal seam is estimated to be nearly 290,000,000t by Chinese group (nearly 50% of it in the 5th seam). That is also estimated to be nearly 346,000,000t by Japanese group (155,000,000t in the 5th seam). Both 1st and 5th seams are composed of sub-bituminous coal. (NEDO)

The technologies are developed for efficiently, economically improving quality of automobile fuels by, e.g., abatement of environmental pollutants present in the oil products. For improvement of hydrodesulfurization rate of gas oil deep hydrodesulfurization process, the catalyst components high in isomerization ability of the hard-to-desulfurize compounds are investigated, and effectiveness of zeolite is confirmed. For production of low-sulfur gas oil by hydrodesulfurization and hydrocracking of heavy oil, the catalyst with small pores is preferable for desulfurization of gas oil as the co-product of the treatment of heavy oil in the presence of catalyst for heavy oil desulfurization. For hydrocracking, the catalysts are prepared, on a trial basis, for achieving the target gas oil sulfur content of 10ppm or less by optimizing the zeolite and matrix properties. For suitability of gas oil qualities, it is found that the hydrogenation step is the rate-determining step among the reaction routes involved in the hydrogenation of difficult-to-desulfurize compounds. The data of low-sulfur gas oil qualities in Europe are collected. (NEDO)

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)

For conversion of solar heat to transportable energy, hydrogen production by direct thermal decomposition of water using concentrated high-temperature solar heat was studied. Water vapor is injected into the tubular target with high melting point and high oxygen permeability at high temperature while heating the target by concentrated solar heat over 2000K. Oxygen in decomposed gas is discharged through an oxygen permeable membrane to extract hydrogen. Solid electrolyte is used as one of the target materials. Oxygen gas in the high-oxygen partial pressure site changes into oxygen ion by accepting two electrons at the target surface, and returns to neutral oxygen gas in the low-oxygen partial pressure site by discharging two electrons at the surface after permeation through oxygen vacancy. In the case of n-type solid electrolyte, to obtain constant permeation of a large amount of oxygen, flow of a large amount of electrons is indispensable in the opposite direction to oxygen ion. Among [(ZrO2)(1-x)(CeO2)x](0.9)(CaO)(0.1), materials of 0.4-0.5 in x seems to be useful as the target material. 7 refs., 7 figs.

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.

To meet the recycling demand effectively, a unit was made a transfer type. Equipment with treatment capacity of 3 tons/h was manufactured and confirmed of its motion. As to the heating equipment, the low-energy consumption structure aiming at homogeneous filling and appropriate ventilation was adopted to control uneven heating and increase in packed bed pressure loss. A tube mill type of the coarse aggregate recovery device was designed/manufactured considering the size of medium and discharge of mortal particles. An attriter type was designed/manufactured considering smooth particle discharge. As to the fine aggregate recovery system, a tube mill type was designed considering the discharge of powder and using coarse aggregate as medium. Moreover, the appropriate transportation of the generated powder and storage method are also considered. The transfer type equipment (unit frame, etc.) was designed/manufactured to make it a unit considered of layout at the time of transporting and assembling the auxiliary equipment such as supply hopper.

This project is a feasibility study to get effects of reducing greenhouse effect gas by repairing Units 8, 9, and 10 (330MW in total) of Schekinskaya thermal power plant and Units 1-7 (450MW in total) of Novomoskovskaya thermal power plant. Both are very old brown coal fired thermal power plants which were constructed during 1947-1967. At present, they are run fired by natural gas. Being very superannuated, they need repair of the facilities. In the adjustment of opinions with Russia, the plan was aimed at substantial reduction of greenhouse effect gas by increasing thermal efficiency of power plant. For it, a 800MW class gas turbine combined cycle power plant is constructed at Novomoskovskaya power plant where there are existing buildings and space for equipment and where gas fuel can be used. As a result of the study, it was indicated that the reduction amount of greenhouse effect gas after the repair becomes 1,853,966 tons/yr as against 3,590,514 tons/yr before the repair. (NEDO)

At the end of 1995, a total abolition of the production of the specified freons (CFC) was achieved. In future, it will be important to proceed with the appropriate recovery/destruction of the CFC, etc. which has been used so far, not only for the protection of ozone layer, but for the prevention of global warming. For the international study of facilities (technology) for destruction CFC, etc., the Technical Assessment Committee (TAC) was installed for destruction technology of ozone layer depletion substances (ODS) under the United Nations Environment Programme (UNEP), and the destruction efficiency (DE) of ODS was set up. In Japan, more than 30 facilities are already handling the destruction of CFC on a commercial basis. The number is expected to increase by the promotion of protection of ozone layer and prevention of global warming. This survey indicated quantitatively and qualitatively based on the TAC DE what the facilities for destruction of CFC should be which were considered of domestic laws in Japan, and was made a guide for existing facilities and ones to be newly installed.

Designing a vessel to sail oceans for an extended period of time requires statistical estimation on different hull responses to waves. To meet the requirement, it is necessary to accurately identify hydrographic conditions (particularly waves) which are considered to be encountered by the vessel. This paper makes clear the statistical characteristics of the wave statistics table presented by Fang et al, and compares them with other processes for discussion. This statistics collection is based on data collected in China, Hong Kong and Japan, including those collected in the Sea of Japan, the Yellow Sea, the North Sea, the East China Sea and the South China Sea. It was found that these data provide results slightly lower than the long-term estimation values derived from data of the global wave statistics (GWS) prepared by Hogben et al. The cause for this was found attributable to the format of the statistical data, especially setting of wave height classes. However, since the data provided by Fang et al include items of detailed information on small sea areas near the Chinese coast lines, the data are thought to provide useful information source in investigating long-term hull response characteristics relative to spatial spread of the sea areas in the North-west Pacific Ocean. 15 refs., 5 figs., 2 tabs.

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)

A desiccant cooling system uses concentrated aqueous solution of an absorbent to reduce humidity, hence the resultant absorbent solution becomes dilute. Regeneration of the dilute solution uses solar heat, where the regeneration characteristics are affected by solution temperature, vapor pressure, water content, air-liquid flow rate, and other factors. Therefore, mutual relationship among these different factors were investigated, and an optimum operating condition was discussed. The regeneration characteristics of the absorbent is strongly affected by temperature of triethylene glycol (TEG). This is because vapor pressure, Ps, in the TEG aqueous solution increases as the TEG temperature rises. This means that preheating the solution is effective in regenerating the absorbent. As the regeneration progresses, the water content, Ww, decreases, and the regeneration rate decreases. This is because of reduction in the Ps in association with decrease in the Ww of the TEG. This suggests that it is important in the absorbent regeneration to reduce flow rate of the TEG aqueous solution as low as possible. Raised air temperature reduces difference in vapor partial pressure between the TEG and the air, resulting in reduced regeneration rate. 5 refs., 9 figs.

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.

For more precise electrical prospecting, the new multicore cable was developed to allow high-density measurement by conventional equipment. Since conventional multicore cables are inferior in cost, length and weight, the new cable is composed of an n-conductor cable, two n-conductor male connectors and n lead wires. For connection of the multi-conductor cable and lead wires, cable sheath is peeled at n points at specific intervals. Sheath of the k-th conductor is peeled at k-th point from the terminal, and restored for insulation after connection of the conductor and lead wire. The male connectors are attached to the both ends of the multi-conductor cable. Since this two-way type cable can be used at every end, the measuring equipment can measure at one divisional point after another of a long measuring line while shifting the equipment from one point to another. All measurements are perfected only with two short cables. Resistivities were successfully measured along the long measuring line of 480m long with 97 electrodes arranged at intervals of 5m. Various electrode configurations were also compared. 1 ref., 4 figs., 2 tabs.

This paper reports the survey results on evaluation of PV power generation in fiscal 1994. (1) On the evaluation technique of energy pay-back time, foreign trial calculation examples by integration method were surveyed. However, there were not many study examples, and the calculation basis of input energy was also ambiguous. The calculation result by input-output analysis in Japan gave the value more than that by integration method, pointing out that indirect input energy is essential. (2) On the evaluation technique of the degree of environmental contribution, CO2 emission of the PV generation system installed on ordinary housing roofs was calculated to estimate reduction of CO2 emission and cost. As a result, PV power generation as reduction measures against CO2 brought a little cost increase. (3) On the latent scale of PV power generation, it was estimated to be nearly 191GW although under no restriction. It was a considerably large value as compared with the current power generation capacity in Japan. 4 tabs.

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. The modified model allowed evaluation of the long-term important role of hydrogen energy, in particular, the capability of CO2 gas reduction all over the world. 28 refs., 92 figs., 56 tabs.

As a realistic measure to reduce environmental pollutants emitted from coal-fueled boilers, a developmental study was conducted of high-efficient combustion systems. In fiscal 1994, four types of topping cycles which are different in system structure and gasifier type were selected, and topping cycles assuming a 300MW-class power plant were trially designed. Further, an evaluation of adaptability of these systems was made, and an selection of the optimum system for the early development was made among the systems. As a result, the evaluation was obtained that `a system using air blown gasifier` is most suitable for conducting the next-stage research. In the element test on the topping combustion technology, collection was made of data of desulfurization activity, desulfurization oxidation mechanism and alkali metal behavior at the laboratory level, data of temperatures and gas concentration distribution in coal gasification, data of simulation of the gasifier reaction, and the other data. 262 figs., 66 tabs.

MÉTODO: Os achados científicos relevantes foram descritos de acordo com a ordem cronológica de publicação e as características dos estudos, se eram pré-clínicos, relacio-nados à violência precoce como fator de risco e, finalmente, achados clínicos em pacientes portadores de transtorno de estresse pós-traumático. RESULTADOS: Foi encontrada uma literatura rica de achados a respeito de disfunções do eixo hipotálamo-pituitária-adrenal e transtorno de estresse pós-traumático. Os achados mostraram que o transtorno de estresse pós-traumático está associado a disfunções deste eixo e de estruturas cerebrais como o córtex pré-frontal, hipocampo e amídala. Os pacientes com transtorno de estresse pós-traumático apresentam um aumento da responsividade dos receptores de glicocorticóides, sugerindo que a inibição do feedback negativo tem um papel importante na fisiopatologia do quadro. Estudos pré-clínicos com modelos animais de deprivação maternal evidenciaram que, dependendo de quando o trauma ocorre, a disfunção do eixo será diferente. Os estudos clínicos mostram que o estresse precoce está relacionado ao desenvolvimento de psicopatologia durante a vida adulta.

For the purpose of conserving energy and reducing greenhouse effect gas, a remodeling project was studied of urea plants constructed from the 1960s to the 1970s. Conditions for being companies for study are as follows: company has a production scale of more than 0.2 million t/y, adopts the complete circulation method, and will continue operation. And, Duncans Industries Ltd. (DIL) was selected. DIL owns the ammonia plant of 3 series x 400 t/d and the urea plant of 3 series x 682 t/d. In the modeling, stripper and carbamate condenser are added to the existing reactor as the main equipment. As a result of the study, the energy conservation effect was 13,667 toe/y, and the amount of reduction in greenhouse effect gas was 42,289 t-CO2/y. The total amount of this project was roughly estimated at 1.517 billion yen. By carrying out the project, the urea production cost is reduced approximately $9/t, but the project becomes unprofitable if the urea price is based on $188.1/t. (NEDO)

This paper describes the survey and discussion on a system to treat microorganisms generated from organic wastes and recover bio-gas energy as an ancillary facility of buildings. The roof of a building is the most suitable location in terms of open space and odor problem, and because the waste liquid after energy recovery can be flown into the city sewage system. Suitable processes for energy recovery are the primary fermentation, followed further by second stage fermentation purposed of reducing BOD. Since rapid enhancement of the efficiency cannot be expected from the present methane fermentation technologies, it is worth discussing to convert the first step from methane fermentation to hydrogen fermentation, for which technological development is indispensable. Permission by the national or local government would be an important condition. Organic wastes treatment systems with different scales may be considered from wastes treatment in each house to treatment of wastes after collection on the whole city basis. Treating wastes with high water content, such as kitchen refuses and human waste is beneficial among organic wastes being collected and treated by local governments. It is beneficial because sorted collection for that purpose can be carried out, and existing incineration systems can be operated more efficiently. (NEDO)

At present, in oil refineries in Japan, the term of the continued operation in oil refining facilities is shorter than that in Europe and America because of the regulation on the open inspection period for boilers and hazardous material storage tanks. As a result, the refining cost is comparatively higher than in Europe and America due to the increase in inspection/repair cost and decrease in operational rate. Therefore, it is becoming important to effectively supply petroleum products by keeping stability in oil refining facilities of the whole Japan and prolonging the term of the continued operation of oil refining facilities, etc. In this R and D, the technical development is conducted which is needed for the long-term continued operation of oil refining facilities. The items for the R and D are as follows: assessment technology of reliability of oil refining high temperature system facilities, assessment technology of reliability of piping/storage facilities in oil refinery, assessment technology of reliability of oil refining power system facilities, technology of management support system in oil refining facilities. In this fiscal year, technical survey, data collection, and construction of the basic concept of developmental technology were mostly conducted. Also conducted were trial manufacture of various probes for non-fracture inspection use, oscillators, etc., and basic design of inspection equipment and trial manufacture of a part of them. And the data acquired were analyzed. (NEDO)

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

Indonesia rich in coal resources consumed 70-million tons of coal in 1999, which covered 17% of its total energy demand. It is estimated that as much as 120-million tons will be produced in 2005, and it is expected that underground mining will increase. Under such circumstances, Indonesia strongly desires that Japan's underground mining technologies be transferred to Indonesia. For the transfer of technologies especially involving production control and management out of Japan's underground mining technologies, Japan dispatched engineers to Indonesia under a mining engineer exchange project, and received and trained Indonesian engineers. Under the engineer exchange project, five engineers were dispatched to Indonesia and gave lectures and on-site training in the period July 9 through August 5, 2000. Japan received seven engineers, who were given lectures and training at the Ikeshima mining field of Matsushima Coal Mining Company in the period November 12 through December 12, 2000. (NEDO)

This paper describes the result in fiscal 1999 of the feasibility study applied with the COP3 clean development mechanism for Bekabad Cement Factory in the Republic of Uzbekistan. One of the existing three old type kilns were diverted and converted into a dry NSP type kiln (having the same production capacity as the present of 726,000 tons a year). This arrangement was intended to enhance the productivity, save the energy, and reduce emission of greenhouse gases and different pollutants by renewing the upper and lower stream facilities and installing such environmental devices as electric dust collectors and bag filters. The total construction cost is US$84,432,000. Reducible energy consumption and reduction quantity of greenhouse gases would be 73,232 toe/year and 176,528 toe/year, respectively, in the single fiscal 2006. The cumulative quantity over twenty-year period until 2025 would be 1,464,640 toe and 3,530,560 toe, respectively. The energy saving effect per US$1,000 would be 17.87 toe, and the greenhouse gas reduction effect would be 43.08 t. In the case of using a soft loan such as the special yen loan for environment application, the internal profit rate after tax would be 7.63%, which is not high as the business enterprise profitability. However, the profit and loss statement indicates creation of profit after two years of operation, hence there is a relative realization possibility. (NEDO)

For disclosing stratigraphy and lithofacies and for clarifying the status of coal beds in the southern Arahan area (55km{sup 2}), South Sumatra, ground surface exploration, borehole drilling, borehole geophysical logging, and seismic reflection monitoring were carried out. The survey covered a rectangular area, 11km from east to west and 5km from north to south and 60m to 130m in elevation. In the ground surface exploration effort, trenching was performed at three spots in coal bed outcrops in an quasi-accurate survey with route gaps of roughly 1,200m. Ten boreholes were drilled. The deepest one was 282.20m deep and the shallowest one 117.80m deep, with the total drilled length measuring 1,643.70m. Seismic reflection monitoring was implemented using three traverse lines (two running north to south and one running from east to west), with the three lines measuring 10.92km in total. VSP (vertical seismic profiling) was carried for borehole ASN17 only. The findings are that there are four kinds of coal beds, that is, A2, B, C, and E spreading all over the area, that their thicknesses are estimated to be 12m, 18m, 7m, and 6-8m, respectively, and that coal beds A2, B, and C are packed into between 80m-deep and 150m-deep levels.

With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

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

Efforts are made to grasp the parts remaining technically unsolved of the ozone-aided technology for creating a comfortable environment, such as ozone-aided enhancement of the decomposition of nondegradable organic matters in the urban sewage and industrial wastewater. Efforts are also made to put in order and analyze data about the said technology, to isolate the current problems and the objects of technical deliberation for the future, and to examine the feasibility of the introduction of this technology. Case studies were conducted for a novel ozone-aided system and the effect is examined of the introduction of ozone-aided treatment into crowded towns, water supply systems, sewerage, and industries that handle paper and pulp, chemicals, electric power, and foods. Findings are mentioned below. The ozone utilizing technology when introduced improves the efficiency of water circulation, reduces pollutants at an excellent rate, suppresses the generation of carbon dioxide, and enhances safety of water resources and water environments. To realize such good results, however, it is important for the ozone to be high in concentration, for the accelerated oxidation and enhanced biofunction processes to be further studied, and for the system to be optimized. It is also found that a technology of appropriate ozone storage will help enhance cost reduction. (NEDO)

To cope with the energy issue and global environmental issue, it is necessary to forcibly promote energy conservation. In the light of the present situation that in Japan only 1/3 of the primary energy consumed is effectively used, policies are being prepared for promotion of the introduction of high efficiency thermal utilization systems including `a project for formation of the environmentally friendly type energy community` promoted by NEDO. However, it is hard to say that the introduction is being actively promoted. The cause is that they do not fully understood the present status of high efficiency thermal utilization systems, procedures for introduction, subsidy system, etc. Therefore, a manual was made to present to self governments and enterprisers who are planning to introduce the system. To be concrete, there are the six systems: cogeneration use thermal supply system, unused energy use thermal supply system, heat storage use thermal supply system, waste use thermal supply system, plant surplus energy use thermal supply system, and cascade type thermal supply system. 28 refs., 38 figs., 42 tabs.

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)

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.

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.

Drilling and survey of deep geothermal exploration wells were conducted to grasp the existing situation of deep geothermal resource and the whole image of geothermal systems in the area where geothermal resource was already developed. In the drilling work in fiscal 1994, 4000m-class rigs and the top drive system were planned to be used for drilling of 12-1/4 inch wells, but 9-5/8 inch liners were used for drilling down to depths of 2550m or deeper since the amount of lost circulation is large and the withdrawal of devices may be very difficult. And in 8-1/2 inch wells, the well was drilled down to a depth of 2950m. As to the deep resistivity exploration technology using electromagnetic method, studies were made of a multiple-frequency array induction logging (MAIL) method, a vertical electromagnetic profiling (VEMP) method, a joint analysis method, etc. Concerning the synthetic fluid inclusion logging technology, containers were lowered into the well and a comparison was made between data of the homogenization temperature analysis of the formed fluid inclusion and those of the temperature log analysis. With relation to the making of deep geothermal structural models, revision was made according to the determination of depths of Miocene formations, Pre-tertiary formations, and the Kakkonda granite. 65 refs., 268 figs., 79 tabs.

With objectives of saving energy and reducing greenhouse gas emission at the Pridneprovskaya power plant in Ukraine, a scrap and build project has been discussed. This project will abolish the unit No.12 among the eight units in the existing coal burning power generation facilities, and install a natural gas burning combined cycle plant comprising of three units each with an output of 100 MW. The new plant facilities will consist of gas turbines, steam turbines, HRSG and auxiliary devices, and an air-cooled synchronous power generator with a capacity of 119 MVA. Use of natural gas as fuel reduces generation of soot, sulfur oxides, nitrogen oxides, and CO. In addition, the hot effluent and waste liquor effluent will decrease from those at the present plant. The required fund will be 30,107 million yen. The energy saving effect of this project is reduction of about 7.5 million tons of crude oil equivalent as a total in 40 years. The greenhouse effect gas will decrease by about 39 million tons as a total in 40 years. The profitability estimation calls for the number of investment recovery year of 16 years, and internal profit rate of 7.32%, wherein the implementation of the project cannot be expected as a project to be carried out by private funds.

In order to promote technical cooperation of Japan with Asia in the energy aspect, site surveys were carried out on improvement in energy consumption efficiency. Electric power supply in Cambodia is made mostly from EDC, whose power generation amount in 1997 was 310 million kwh, while the power sold was 230 million kwh, with 26.1% of the total generation amount, or 80 million kwh being wasted as the loss. Existing power generation facilities are old and small in scale, made by the former Soviet Union making the repair difficult. The loss is enormous because of aging in power distribution facilities, overload operation, and power stealing. The efficiency is extremely poor, whereas improvement in efficiency of the existing facilities is indispensable to cope with the anticipated increase in the demand. In Bangladesh, 90% of the power is generated by using natural gas produced in the eastern part of the country. Many power plants are experiencing decreased efficiency due to the facility aging and insufficient and improper maintenance. The power transmission and distribution departments have had a large loss in power, which has become one of the most important issues. The loss exceeds 30%. The government is trying to achieve efficiency improvement in the electric power business through introducing the principle of competition by establishing new private companies. However, this approach is facing severe objection from the governmental and public labor unions, making the future development opaque. (NEDO)

This paper describes the research result on the conceptual design of the total system for the WE-NET project in 1996. Basic conditions are as follows: solid polymer water electrolysis, hydrogen combustion turbine power generation, hydrogen transport/storage through ammonia medium, power generation scale of 1000-4000MW (2-5 yen/kWh), and transport distance of 5000-20000km between supply and consumption places. The system efficiency was estimated to be 68% and 23% at an ammonia arrival time and power sending end, respectively, and it was dependent on a transport distance, while no power generation scale. The power cost was estimated to be 7 yen/Mcal and 33 yen/kWh, respectively. The system efficiency at a sending end was lower by 15% and 2% than that of the liquid hydrogen and methanol system, while the power cost was higher by 0 and 8 yen/kWh, respectively. It was necessary for loss reduction of this ammonia system to develop a new high-efficiency ammonia synthesis process, and hydrogen separation (decomposition/refining) process. 80 figs., 52 tabs.

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.

In order to discuss effectiveness of physical exploration in the Sakonishi prospect in the Hida area, physical exploration was carried out by utilizing bored wells. This area contains the Kamioka mine, one of the major base metal mines in Japan, where electrical exploration has been attempted several times in the past. No effective results have been obtained, however, because specific resistance contrast between mine beds and base rocks is too small, and the topography is too steep making site workability inferior. As part of the investigations on geological structures over wide areas, electrical logging (specific resistance and natural potential) was performed in fiscal 1995 and 1996 by utilizing the boreholes. Induced polarization logging was also conducted on the same boreholes. A traverse line on the ground with a length of 600 m and boreholes were used to execute specific resistance tomography. Clear extraction was possible on a fault structure which is thought related with limestone distribution and mine bed creation. However, it was not possible to identify upward continuity of zinc ores expected in the exploration. Because of not large a specific resistance contrast between zinc ores and base rocks, it is difficult to find mine bed locations only from the information on the specific resistance. 5 refs., 5 figs., 1 tab.

Survey was conducted on the actual state and the potentiality of reusable energy (RE) in the South Pacific nations. The countries to be surveyed were Australia, New Zealand, Papua New Guinea, the Fiji, the Republic of the Marshall Islands, and the Republic of Nauru. The subject RE are photovoltaic power (PV), solar heat, wind force, biomass, hydraulic power and geotherm. The survey items were as follows; RE policy and promotion programs, technical level of makers, RE supply areas and population for independent/linking type electric power systems, population of non-electrification areas, meteorological data, foreign investment policy, feasibility for introduction if RE not yet introduced, and potential of promotion if RE already introduced. Propositions are as follows. Australia and New Zealand, having a comparatively large population and a stable government, are the two most important markets for RE technologies. The South Pacific nations have a markedly small population, providing a limited market for RE systems. Papua New Guinea, being a country possessing natural gas resources, has a chance of developing photovoltaic and fossil energy hybrid systems. The Fiji shows possibility for hydraulic, wind force and biomass power generation. (NEDO)

Slag released from an electric furnace consists mainly of waste steel. There are two types of slag, namely, oxidized slag and reduced slag. Reduced slag, which is generally in the form of powder, is difficult to recycle as compared with oxidized slag. However, with a hydraulicity, some reduced slag is expected to be useful as hydraulic material. Test results obtained here show that the hydraulic properties of reduced slag powder can be improved by mixing it with gypsum and that the resultant mixture can serve to improve the prooperties of soft clay. Another study is made to determine the potential, as hydraulic material, of mixtures of reduced slag powder and waste gypsum material with a high gypsum content released from an oxidized titanium production process. The hydraulicity is found to develop as a result of the formation of a hydrate of calcium aluminate which is contained in the slag. Addition of water to the hydrate and gypsum cause the formation of ettringite, leading to an increased uniaxial compressive strength. These findings indicate that the above-mentioned mixture can be useful to improve the hydraulic properties of coal ash to be disposed of at landfill sites. 5 refs., 5 figs., 1 tab.

By the use of superconductive technology, the following are aimed at: marked reduction in power loss of electrical equipment and power transmission path, and size/weight reduction in electrical devices by high current/magnetic flux density. The superconductive technology has advantages such as great energy saving effect, CO2 reduction and global environmental preservation. As an example, concerning the superconductive generator now being developed under the New Sunshine Project, power loss can be reduced by half, and by the use of high magnetic field, size/weight can be reduced such as reduction in rotor diameter and reduction in weight by half. Further, as an innovative system, cited are the superconducting magnetic energy storage system (SMES) and flywheel energy storage system. The superconducting magnetic levitation railway, medical use MRI, etc. have also innovativity which is difficult to get in the conventional technology. Effects are also expected of introducing the process development using superconducting magnet such as magnetic separation, electromagnetic metallurgy, electromagnetic agitation and monocrytal growth convection control. Also cited is Josephson electronic device. High performance SQUID in bio-magnetic/non-destructive inspection is also expected to be developed. (NEDO)

With the purpose of establishing fundamental technologies for ceramic porous materials that are excellent for artificial bone for a living body, evaluation technologies were developed for mechanical properties and biocompatibility, with fiscal 1999 results compiled. Performed for the examination of the mechanical properties were flexural test, compression test, tensile test, shearing test, torsion test, fatigue test, etc., with an evaluation testing method studied assuming that ceramic porous materials were applicable to implanting members. In the evaluation of biocompatibility, five kinds of osteoblast-like cell lines were cultured on a plastic disk and a dense hydroxyapatite disk, with adhesion and proliferation of the cells compared. Since these osteoblast-like cell lines adhere and proliferate on the surface and in the pore of hydroxyapatite, evaluation of the biocompatibility such as cell affinity was found possible with this in vitro method. With the view of obtaining principles for designing new bioactive ceramics, a method was developed for evaluating apatite-forming abilities of metal oxide gels having different compositions and structures in simulated body fluid.

The feasibility study is conducted for introduction of the district energy-saving measures in City of Aizu Wakamatsu, for which the actual situations of energy consumption and promising energy-saving measures are surveyed. The city has a typical basinal weather, cold in winter and very hot and humid in summer, and tends to have a longer air-condition period in a year. It is considered that there are many wasteful energy consumption items to be studied for reduction. In the area of moving means, dependence on public transportation systems is considered to be relatively low, suggesting that there are much space of reducing transportation energy by the measures such as self-imposed control on use of private cars, promotion of utilizing public transportation systems and fuel-saving type driving throughout the city. The promising energy-saving measures studied to verify the effects include introduction of PVM analyzers for establishing better cost/effect relationship between power consumed by air-conditioners and pleasantness; introduction of garbage power generation, co-generation and high-efficiency illuminators; improvement of power-factor; and demand control for air conditioning, rationalization of power-receiving facilities, introduction of systems for saving flushing water and improvement of air conditioners' outdoor facilities.

In an ICFB boiler, the fluidized bed is separated by a partition into the main combustion and the heat recovery chambers. The flows in these chambers are generated by using silica sand as the fluidizing medium. To determine the overall heat transfer coefficient (HTC) of the boiler`s panel type immersed heat transfer tulles, combustion tests were performed with wire rim tires. The overall HTC of a panel tube array was lower than that of a zigzag tube arrangement. In practice, the heat absorbed by the fins makes the coefficients of either type of tube array almost identical. The air flow rate in the circulating bed at the loot Tom of the heat recovery chamber can be changed to control the overall HTC to a value virtually identical with that of a zigzag tube array. The combustion of wire rim tires leads to a buildup of wires in the zigzag array hampering the transfer of heat. Yet, the panel type array showed no buildup so that it was possible to maintain steady operation with this type of tube arrangement. 8 refs., 10 figs., 2 tabs.

Commercialization survey was performed on the mines in the Manguerra district in the Philippines by means of geological structure surveys. The site surveys included geological and test drilling surveys, and those on conditions for developing underground mining mines, and infrastructures. The geological survey area spread out about 5 km{sup 2}, two test wells were drilled (to depths of 330 m and 290 m), trench survey was performed on 58 locations, and coal sample collection and analysis were carried out on eight locations. Furthermore, surveys were extended to the Manguerra mine operating status, on-the-ground facilities, roads for transportation, marketing, and related laws and regulations. As a result of the surveys, the Manguerra district was suggested of frequent sea water inundation into the coal field, leading to a view that the district is unstable from the viewpoint of development of coal beds. However, samples collected from the existing mining area indicated to have less water content and ash and high calorific power. The coal has high product value. The result of coal quantity calculation indicated 320122 tons as the total of defined and estimated quantity. The great depth mining plan was prepared from the viewpoints of actual yield, productivity, safety aspects, technological enhancement, and suppression of additional investments to minimum. (NEDO)

ED-1 of 97m{sup 2} in first floor area and 81m{sup 2} in second one has, on its roof, the photovoltaic power generation system, the solar hot water collector which supplies hot water by circulating heated antifreezing solution into a hot storage tank, and the solar hot wind collector which largely contributes to energy saving together with a hot room named an S unit on the first floor. The small S unit faced toward the south adjacent to a dining room is made of timber and thermal insulation glass. The S unit stores heat in a floor by taking the sunlight into a room in winter, while enhances a heating effect by discharging stored heat in nighttime. In some cases, duct circulation of heated wind is possible. Solar radiation of 90% can be removed by outside glass fiber screen of the S unit together with double glazing coated by special metal film. Roof material is superior in heat insulation, air tightness and energy saving, while floor material in sound insulation and heat storage. The target for reducing energy essential to human life by 70% was thus nearly achieved. 1 fig.

With an objective of saving energies and reducing greenhouse gas emission, discussions were given on a modernization plan for the Chhatak cement factory in The People's Republic of Bangladesh. The Chhatak cement factory having a nominal production capability of 267,000 tons a year uses mainly wet-type long kilns of old type, consuming a great amount of natural gas. The present plan has discussed adoption of the Japanese energy saving technologies. The technologies use a vertical roller mill for raw material pulverization, a suspension preheater and a short kiln for clinker sintering, a grate cooler for clinker cooling, and the pre-crushing system. The result of the discussions provided the prospects of reduction in the natural gas consumption at 50%, and reduction of electric power consumption at 16%. This will mean the annual reduction of about 22,000 tons as converted to crude oil. The CO2 reduction amount would reach 51,800 tons a year. The total investment amount would be US$37,327,000. The result of the financial analysis according to the case studies appears severe, wherein reduction of the various expenses is desired possibly by the finance from Japan with generous conditions.(NEDO)

Under study is the modification of the four antiquated 300MW brown coal-fired power plants of the Ryanzanskaya thermal power station. Under the modification program, the plants will be burning a mixture of 60% coal and 40% natural gas for an increase in efficiency and for a great decrease in greenhouse gas emission. The amount of greenhouse gas emission of 6,858,592 tons/year before the modification will be reduced by 19.4% to 5,532,198 ton/year. The budget for the modification will call for 719,731,700 US dollars. EIRR (economical internal rate of return) is calculated based on the figures provided by the Russian office concerned about the current fuel cost and the current rates for the supply of electricity and heat. It is found that EIRR fluctuates depending on the ruble/dollar exchange rate. Although it does not pay at the current exchange rate, yet, when a US dollar is worth 13.0 rubles, an EIRR of 15% will realize at an availability factor of 70%. The same result is obtained when the availability factor is 80% and a US dollar is worth 14.8 rubles. There is a plan to fire the plants with 100% natural gas in the future. If the plan is implemented, a modification to incorporate gas turbine combined cycle will become feasible. (NEDO)

Discussions were given on conversion of shaft kilns mainly used at Tianjin Cement and Huaxin Cement to the fluidized bed cement kiln of the most advanced type. Possibility of energy conservation in China, that is reduction of carbon dioxide emission, was evaluated. This system has been developed by the Center for Coal Utilization, Japan. The system is characterized by reduction of greenhouse effect gas emission, elimination of the problem of dust scattering from sintering facilities, stabilized production of high-quality clinker, capability of using low-grade coal and anthracite, and reduction of cement production cost. As a result of the discussions, the reduction rate of greenhouse effect gases was found about 17 to 33%. The cost effect may be calculated as 2 to 5 thousand yen per ton of CO2 reduction amount assuming the system life of 20 years. If this process has been diffused into China, the quantity of CO2 to be reduced will reach about four million tons annually assuming a diffusion rate of 10%. This project shows as high profitability as about 20% at IRR, and the system is more advantageous economically than the shaft kiln. (NEDO)

Commercialization survey was performed on the coal beds in the Kalewa area in the Union of Myanmar by means of geological structure surveys. The site surveys included on-the-ground survey, test drilling survey, sample collection and analysis, and infrastructure survey. The on-the-ground survey area spread out about 5.5 km{sup 2}, wherein nine test wells were drilled (for total distance of 2,046.74 m), and coal and rock sample collection and analysis were carried out on six samples. The infrastructure survey was performed on coal transporting roads, and barge loading planned points and facilities. As a result of the test drilling survey, existence of coal beds with thickness of 4 ft, 9 ft and 6ft was identified. Since the 9-ft bed in particular exists stably with inclination of 40 to 42 degrees over the whole subject area, it was made clear that the bed can be the object of mining as the main coal bed. The coal is the ordinary coal with such good qualities as ash content of 4.72%, total sulfur content of 0.22%, and total calorific power of 6,500 to 6,570 kcal/kg. The defined coal quantity for the 9-ft bed is four million tons, or 7.7 million tons in total if the estimated coal quantity is added. The quantity will amount to 15.3 million tons when those of the 4-ft and 6-ft beds are added. (NEDO)

Introduction of geothermal heat pump systems, which depend on temperature differential, is investigated for urban areas, which have large energy demands. Results of the surveys on the current situations of geothermal heat pump (GHP) systems indicate that they have already numbered 300,000 units in USA and totaled more than 50,000 units in Switzerland and Northern European countries, and that they are increasing at an annual rate of higher than 10%. The results also indicate that introduction of these systems are well feasible in Japan, which generally has better topographical conditions than American and European countries, and the GHP system with vertical ground heat exchanger is investigated for its topographical and environmental considerations. These systems could annually abate approximately 52 million tons of CO2 (4.3% decrease), if disseminated to all households. They are also expected to help control the heat island phenomenon, and reduce peak power consumption. The technological problems to be solved before these systems are massively disseminated including development of small scale drilling rigs and preparation of drilling manuals. System standardization and introduction of subsidy systems are also needed to massively disseminate these systems. (NEDO)

Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

In recent years, a system has been proposed that utilizes river heat, air-heat, exhaust heat from a cooler, etc., in addition to natural energy for the heat pump. With the introduction of such system, the amount of energy used and that of CO2 exhaust will be greatly reduced, but annual expenses will be increased as it stands. In order to improve the cost efficiency of the system, a proposal has been made for the introduction of an economic policy such as the carbon tax and a low interest financing system. With these matters in the background, the subject study predicts the production of solar cells in the future and, on the basis of this production, determines the price, conversion efficiency and equipment energy of solar cells in the future. Using these values and taking into consideration the introduction of the carbon tax and the low interest financing system, the optimum area was determined for solar cells and heat concentrators in a future residential solar/air-heat energy system. The carbon tax, being imposed on all CO2 discharges, had a large effect. Moreover, as the tax increased, annual expenses decreased for the solar/air-heat system. 3 refs., 6 figs.

Efforts are put into the study of direct iron making for use in a closed system where heat energy from a multi-purpose high-temperature gas furnace expected to be developed in the near future will be utilized for iron making. The researches, carried out for the establishment of technologies necessary for designing, building, and operating a pilot plant dimensionally suitable for connection to a 50MWt multi-purpose high-temperature gas furnace, cover the plant total system, a high-temperature heat exchanger, ultrahigh-temperature alloys, high-temperature insulating materials, a reduced gas generating unit, and a reduced iron making unit. When the effort is evaluated as a whole, it is found that the newly developed system is effective in preventing pollution, emitting but 0.1Nm{sup 3} of SOx per 1 ton of crude iron against the 0.4-0.9Nm{sup 3} emitted by a blast furnace/converter iron making mill. It is also found effective in reducing fossil fuel dependence and in enhancing energy source diversification.

Petropavlovsk-Kamchatky (P-K) city in Kamchatka, Russia is operating hot-water district heating using heavy oil boilers and waste hot water of thermal power plants as heat sources. Feasibility study was made on district heating using natural geothermal hot water and/or geothermal heat pump systems as heat sources of hot water supply for reduction of greenhouse effect gas emission. Among 3 areas including geothermal hot water, use of hot water in K area was impossible because of lower temperature and less spring water. Use of hot water in P and UP areas was impossible as primary hot water because of temperature drop to 64 degrees C during hot water supply toward P-K city. The building heating operation test was carried out using the geothermal heat pump system installed in a newly drilled heat exchange well of 100m deep. As a result, sufficient heat recovery was achieved for heating. If all of 49 boiler houses for heating are replaced with such geothermal heat pump systems, CO{sub 2} reduction was estimated to be 520,000t/y. (NEDO)

Although China ranks first in the world in the manufacture of cement, yet the energy consumption rate is high and there remains room for improvement. Effective utilization of energy at cement making plants will not only profit the industry but also contribute to the stabilization of energy supply for China. The model project on power generation using cement waste heat implemented at Ningguo Cement Plant was concluded successfully. For the purpose of enabling China to domestically manufacture the equipment, the installation of such equipment at Zhujiang Cement Plant and Liuzhou Cement Plant in Guangxi Zhuangzu Zizhiqu was assumed, and their locations and plant operating conditions were studied. In addition, surveys were conducted of manufacturers of important components of the power generation equipment such as boilers, steam turbines, generators, and breaker boards. Two manufacturers were visited for each of the components, and they were checked for records of manufacturing similar equipment, quality assurance and process management capabilities, and for ability to satisfy required specifications. Among the visited manufacturers were Nanjing Turbine and Electric Machinery Co., Jinan Power Equipment Factory, and Hangzhou Boiler Works. Based on the results of the surveys, it was concluded that the model project may be implemented. (NEDO)

The paper summed up the FY 1999 results of the survey conducted based on the agreement on the Tanjung Enim IV coal exploration project which was concluded between NEDO and Indonesia's Ministry of Mining Energy. The survey was made for an area of approximately 40km{sup 2} which is a north block of the south Arahan region, Tanjung Enim, South Sumatra, Indonesia. To grasp the succession of strata/rock facies/geological structure and the state of existence of the coal seams to be drilled, surveys were conducted on ground surface and boreholes. A total of 10 holes was test-drilled, and all the boreholes were physically logged. As a result of the survey, each of A1, A2, B, C and E coal seams was confirmed as main seams. A1, A2 and B seams are low in ash and sulfur contents with heating values of approximately 4,800 kcal/kg, C seam is high in sulfur content, and E seam is high in heating value, 6,000 kcal/kg. As coal seams for open pit mining, existence of A, B and C seams is expected which lay in the shallow part from ground surface to sea level of 0m and in the range of depth of approximately 100m. The proved coal reserves of these coals were estimated at 189 million tons. (NEDO)

Discussions were given on the modification plan for Khabarovsk Thermal Power Plant as part of the basic survey on promotion of joint project implementation based on the COP3. The plan calls for shutting down the overaged power plant No. 1 (462.5 MW) and newly building the power plant No. 4 with high efficiency to reduce CO2 emission. The plant will use coal, which is mined extensively in the region. The plant will be a combined heat and power plant with a total power generation output of 576 MW and a total thermal output of 1140 Gcal/h. Effect of reducing CO2 emission as the result of this modification plan will be as much as about 1.2 million tons annually. The plant will use coal as fuel in the beginning, but if it uses natural gas in the future, for which pipeline construction from Sakhalin has been planned recently, the CO2 emission reducing effect will reach 2.4 million tons. Internal profitability was calculated with the CO2 price set at zero US dollars and with the foreign exchange rate varied, for a case of firing coal for 30 years. The profitability may vary largely according to the foreign exchange level, such as profit rate of 5.47% at 20 roubles to a US dollar, 11.04% at 12 roubles, and 21.22% at 6 roubles. The profitability should be judged somewhat low under the current exchange rate of 20 roubles to a dollar. Financial provision with a favorable condition is strongly desired. (NEDO)

For the purpose of contributing to the resource recycling and global environmental preservation, the R and D of metal base scrap regenerative utilization technology were conducted, and the report on the finally obtained results was summed up. As to the technology to remove impurities by the solid phase treatment, the Cu removal rate of more than 96% was made possible by the low temperature fracturing technology, and that of more than 90% by the hue difference discrimination separation system technology. From the results of the FS on the low temperature fracturing technology applied to car scraps, it was found out that the present price condition is not economically efficient in the present price condition, but a possibility of achieving the removal rate of 54% in the initial plan was obtained if applying the hue difference discrimination separation system to the pretreatment. Concerning the Sn removal, the Sn removal rate of more than 70% was obtained by the gaseous phase sulfuration method, and that of more than 50% was obtained in Sn removal/Cu removal/Zn removal by the oxidation reaction method. The targets were achieved. Relating to the treatment of impurities by melting (liquid phase), the Cu removal/Sn removal technology under reduced pressure was effective in vacuum melting furnace of 2-ton scale, but the needs for the development of large capacity plasma torch were recognized in that of 40-ton scale for practical use.
