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)

The project for exchanging engineers has been implemented, in order to improve production and managemental techniques of coal mining engineers in the Asia-Pacific region, promote smooth and efficient projects for surveying overseas geological structures, and facilitate stable supply of overseas coal to Japan. The FY 1998 project was concentrated on Vietnam, to which Japanese coal mining engineers were sent, and from which production management engineers were invited to Japan as trainees. The Japanese engineers sent to Vietnam educated the underground coal mining techniques. The Vietnamese management engineers invited were trained for, e.g., production management techniques (e.g., those for workplaces and organizations) in the Japanese mines, administrative management techniques, and techniques to improve safety and productivity in the mines. Coal Energy Center and Taiheiyo Mining's Kushiro Mine provided training facilities. (NEDO)

Full Text Available A quantidade de energia metabólica gasta em transportar a massa corporal de um sujeito por unidade de distância tem sido definida como custo energético da locomoção, ou especificamente para natação, o custo de nado. As diferenças no custo de nado entre os indivíduos parecem ser influenciadas por dois principais fatores, a resistência hidrodinâmica e habilidade técnica do nadador. O menor custo de nado apresentado pelas mulheres tem sido atribuído a menor resistência hidrodinâmica decorrente de menor tamanho corporal, maior percentagem de gordura e melhor posicionamento horizontal. Porém, essas diferenças no custo de nado entre homens e mulheres desaparecem quando corrigidos para o tamanho corporal. Em relação às crianças, o maior custo de nado comparado com o dos adultos quando corrigidos para o tamanho corporal pode ser explicado principalmente por menor habilidade técnica apresentada por elas. Para indivíduos com as mesmas características antropométricas, melhor habilidade técnica e maior tamanho da superfície de propulsão, associados a aumento na eficiência propulsiva, podem reduzir o custo de nado. Quando se comparam os diferentes estilos, o mais econômico é o crawl seguido pelo de costas em qualquer velocidade de nado.

The survey was conducted based on 'Scope of work for detailed coal exploration in the Tebulan East block of the Merit Pila coal field, Sarawak, Malaysia' concluded on June 19, 1993 between NEDO and Global Mineral which owns the mining right. The field survey was for the geological survey, survey of conditions of open pit mining, and infrastructure survey. The confirmed/estimated coal amount totaled 22,65 million tons in 4 coal seams. The all sulfur content is low, approximately 0.12%. The heating value is 5,820 kcal/kg. As to the infrastructure, various conditions are good for transportation, shipping facilities, etc. from mine site to truck transport/barge transport/external route shipping. The drilling was planned to be made by open pit mining by the truck and shovel system, and the scale of the planned production was 0.3 million tons. The ash is low in amount, and there was no coal preparation. Clean coal is produced by crushing, sieving and washing. Attached were the borehole log (JN9940782), route map, and trench sketch (JN9940783). (NEDO)

The paper reported the FY 1992 basic survey for the coal mine development/industrialization in the Embalut West area of Indonesia. The geological structure in the survey area is under the Loa Haur Syncline which lies approximately north and south to the west of the area, and is regarded as the stabilized structure having no faults. The three beams from the upper part, S14, S13 and S12, are assumed to be the coal seams to be drilled. The average seam thickness is 1.17, 2.35 and 3.09m, respectively, and the continuity is good. In S14 beam, which is thin, it is difficult to mine coal using equipment. The theoretical minable reserve of the three coal seams is 18,859,000 tons. The recoverable coal reserve is 12,258,000 tons at a mining recovery of 65%. In case of annual production of 0.4 million tons, it is possible to mine more than 30 years. The coal is classified into a subbituminous coal-brown coal rank of the JIS coal classification. It is high in water content and medium in heating value, but is an environmental protection type with low ash and low sulfur content. In the case of mines in the Mahakam River basin, barge transport is indispensable. For sea transportation, the following should be studied in the light of the international price competition: reinforcement of shipping facilities on Mahakam River, increase in barge size, joint use of Balikpapan Coal Center, etc. (NEDO)

A fundamental coal mine development investigation was carried out in Batulicin Area, Kalimantan, the Republic of Indonesia. The investigation included ground surface surveys, preparation of topographical maps and geological maps, trial drilling investigation, physical logging, chemical analysis, and infrastructure investigation. The trial drilling investigation was intended to identify the existence conditions of coal beds and coal quality, and was performed by forming grids with about 500-meter interval, and using 21 trial drillings to depths of 104 to 240 meters for a total drilling length of 3463 meters. The physical logging included electric logging, radioactivity logging and pore size logging, and the trial drilling cores were subjected to chemical analysis. For infrastructures, investigations were carried out on necessity of modifying existing roads, privilege relationship, the current status of barge loading points, water depths, and land acquisition. The result of the investigation revealed that minable coal quantity in underground mining of the coal bed B would be 13.189 million tons, and that annual production of original coal at 733,000 tons would be possible by adopting a long-wall type mechanized coal mining system. 14 refs., 99 figs., 25 tabs.

For the work of searching for coal beds, comparison is made between the geological structure of the object area, which is predicted, before actual investigation, by a close scrutiny of the result of oceanic pilot boring conducted in the past, result of geophysical exploration, and the geological features of galleries already in presence in the vicinity, and the result obtained from galleries drilled actually for the investigation. The investigation was conducted at the Ikeshima coal mine, Nagasaki Prefecture. In this fiscal year, 5 investigation galleries were drilled, totalling 1640m in length, and, in the mine, geological surveys, survey and measurement, coal quality evaluation, water emergence investigation, boring for coal, etc., were carried out. Comparison was made, and, though in the 2nd Minami No. 06 air duct there was no important difference detected between the prediction and the actual result, some faults were found to exist which had not been predicted by seismic exploration on the ocean. In the 2nd Minami No. 5 air duct, the actual geology was not different from the predicted geology, this endorsing the usefulness of boring for coal. In the 2nd Minami No. 01 gallery, direction and inclination were not greatly different from what had been predicted, but some faults which had not been predicted were discovered. These faults had escaped the scrutiny of neighboring coal beds and pilot boring. (NEDO)

Full Text Available OBJETIVO: Investigar os efeitos da suplementação com ácidos graxos ômega-3, nas doses de 0,5 e 1,0g/kg/dia, nos lipídeos sangüíneos de ratos submetidos ou não ao protocolo do nado. MÉTODOS: Ratos Wistar foram divididos em grupos: controle, controle+nado, ácidos graxos ômega-3 e ácidos graxos ômega-3+nado. Os ácidos graxos ômega-3 e ácidos graxos ômega-3+nado receberam suplementação; os demais receberam água por gavagem. Os controle+nado e ácidos graxos ômega-3+nado foram submetidos ao exercício. Foram avaliadas as concentrações plasmáticas de colesterol total, triglicérides e lipoproteína de alta densidade, antes e após os procedimentos experimentais. RESULTADOS: No protocolo de 0,5g/kg/dia, em relação às concentrações de colesterol total, foi observada redução significativa proporcionalmente maior no grupo ácidos graxos ômega-3+nado, apesar de o grupo controle+nado e o ácidos graxos ômega-3 também terem apresentado diminuição. No ensaio de 1,0g/kg/dia todos os grupos apresentaram uma diminuição que foi maior, respectivamente, no ácidos graxos ômega-3+nado e, a seguir, no ácidos graxos ômega-3. Quanto aos triglicérides, foram encontradas reduções em todos os grupos experimentais, que foi maior no grupo ácidos graxos ômega-3+nado, do protocolo de 0,5g/kg/dia, enquanto que no de 1,0g/kg/dia a diminuição foi significativa apenas nos grupos ácidos graxos ômega-3 e ácidos graxos ômega-3+nado. Quanto ao HDL, no protocolo de 0,5g/kg/dia foi encontrado aumento nos animais que não foram suplementados, enquanto que em todos os grupos de 1,0g/kg/dia houve uma diminuição do HDL. CONCLUSÃO: A suplementação com ácidos graxos ômega-3 nas doses 0,5 ou 1,0g/kg/dia, associada ao nado, reduzem as concentrações plasmáticas de colesterol total e triglcérides, mas estudos adicionais, também com outras doses, são necessários para a compreensão da relação entre a ingestão de óleo de peixe e

With an objective to identify stratigraphy, geological structures, coal bed existing status, and coal quality of major coal beds in the north and central district of the area to be surveyed in the Red River delta, test well drilling, physical and seismic exploration, and coal composition analyses were performed. The area to be surveys is a typical delta where irrigation canals are running in all directions. Three test wells were drilled with drilling lengths of 640 m for TD3, 700 m for TD4 and 900 m for TD5. Coring was performed to depths greater than the Tertiary deposit. The seismic exploration was executed along three exploration lines. Total distance was 25 km. In addition, the VSP investigation was carried out on TD3 and TD5. The stratigraphy is composed from below of the Phu Cu bed (Neogene period: marine deposit) , the Tien Hung bed (Neogene period: continental deposit), and the Tai Doung bed (quaternary deposit), in which the bed that holds coal beds is the Tien Hung bed. The beds are very stable as the geological structure, but the constituting rocks are soft and fragile. Anticipated coal beds exist in depths greater than 1000 m. The coal quality is of low ash, low sulfur, medium in calorific power, and contains little gas. (NEDO)

MÉTODOS: Foram avaliados 170 pacientes com diagnóstico de paraplegia e tetraplegia, em três etapas - levantamento de dados em prontuário, entrevista oral e avaliação do padrão do nado. Os resultados apontaram que grande parte dos pacientes não entrou na piscina ou realizou nado após a lesão medular. A avaliação da adaptação ao meio líquido após a lesão medular demonstrou que grande parte dos pacientes realizou a imersão e flutuação de forma independente, porém, apresentando dificuldade em mudar de decúbito dentro da água. Apenas uma pequena porcentagem retomou a natação após a lesão medular; foi também verificada redução no total dos sujeitos que nadavam regularmente antes. A avaliação apontou que os nados crawl e de costas foram realizados por metade dos avaliados; apenas uma pequena parte realizou nado de peito.

These are tables and drawings for the FY 1993 basic survey for the coal mine development/industrialization in the Muara Lakitan area of Indonesia. The geological structure in the survey area is under six sets of the anticline/syncline structure which have an NW-SE axis of fold, and exposes the Muaraenim seam repeatedly. The theoretical coal reserve in the depth down to 200m of each of the seams, Nos. 1, 2, 5, 12 and 13, which are great in coal seam change and exist relatively stably, is 143 million tons. The depth for adoption of the shovel/truck system open pit mining seems to be 50m or shallower, and the production is to be approximately 70 million tons.

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.

Sin embargo, no se han llevado a cabo estudios que relacionen cuantitativa y cualitativamente la intensidad de estrés al que es expuesto un animal y la expresión de proteínas del hipocampo. Objetivo: evaluar la expresión diferencial de proteínas hipocampales en ratas Wistar-UIS, expuestas a diferentes niveles de estrés inducido por el nado forzado. Materiales y métodos: se utilizaron 30 ratas Wistar-UIS machos distribuidas aleatoriamente en 3 grupos según el tiempo de exposición al nado forzado como estímulo estresor (0, 5 y 15 minutos. Después de 24 horas se extrajeron los hipocampos dorsales y se realizó electroforesis bidimensional de las proteínas extraídas. A continuación, se llevó a cabo el procesamiento de las imágenes de los geles obtenidos utilizando el software PDQUEST 2D. Aquellas proteínas en las se detectaron intensidades asociadas a los tiempos de exposición al estímulo, se identificaron de manera presuntiva utilizando la base de datos bioinformática Export Protein Analysis System (EXPASY. Resultados: de acuerdo con el análisis proteómico y bioinformático se identificaron 60 proteínas, de las cuales, 38 eran comunes al hipocampo derecho e izquierdo; 13 del hipocampo derecho y 9 del izquierdo.

For the purpose of elucidating a possibility of existence of geothermal reservoirs in the Haneyama area, Oita Prefecture, survey of the geological structure (geology/alteration zone) was conducted. The survey was made for the area of 280km{sup 2} lying from Kusu Town to Kokonoe Town, Oita Prefecture in terms of the route survey of 174km, fabrication/judgement of 52 rock slices, whole rock chemical analysis of 21 rocks, age determination, analysis of rock mineral, X-ray diffraction, literature collection, etc. As a result of the survey, the following conclusion was obtained. When considering a possibility of existence of heat source near this area, the area near the present volcanic front was regarded as promising. The fracture structure in the depths seen in the gravity structure (part of sharp dip of gravity) is more closely related to activity of geothermal water than the active structure of E-W system near the earth surface newly formed and is important when considering the existence of geothermal resource. The periphery of the Shishimuta sedimentation zone where Takigami, Oodake, Hacchobaru and Oguni are located was especially regarded as an area propmising of geothermal energy. In the survey area, the geothermal potential was the highest near Noya - Mizuwake Pass. (NEDO)

Introduced herein is an application of 2D resistivity survey to a volcanic rock area where the survey result is difficult to interpret because of its complex geological structure. In a dam site survey, main problems involve the permeability of water through faults and weathered, altered zones. At this site, a 2D resistivity survey was conducted, a 2D geological structure was deduced from the resistivity section, and the result was examined. It was found that resistivity distribution was closely related to hydrographic factors, but no obvious correlation was detected between rock classes and R, Q, and D. In conducting investigations into a section planned for a highway tunnel, it was learned that the problem was a volcanic ash layer to collapse instantly upon absorbing water, and the distribution of the ash layer, not to be disclosed by boring, was subjected to a 2D resistivity survey. The survey was conducted into the structure above where the tunnel would run, and further into the face, and studies were made about what layer was reflected by the resistivity distribution obtained by analysis. The result of the analysis agreed with the details of the layer that was disclosed afterward. 4 figs., 1 tab.

The survey was conducted based on 'Scope of work for detailed coal exploration in the Pondok Labu East area of East Kalimantan Province, Kalimantan, Indonesia' concluded on June 16, 1995 between NEDO and P.T. Tanito Harum which owns the mining right. This is a BIP survey report. The strike/dip read from the isobath diagram drawn from the result of the boring little agreed with the stratification in the BIP survey. The BIP stratification is greater in strike and dip than in depth. The latter possibly includes false beds and surfaces cut-off/separated by channel, but roughly speaking the structure becomes such a structure as in the isobath diagram. It suggests that there is local undulation everywhere. Judging from the appearance frequency of open type cracks and the size of hole, there are no problems of the crack type decline at frequency of less than one per 5m at the time of drilling mine roadway. The state of upper/lower basement was not good. Refer to the paper (JN9940854). (NEDO)

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.

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.

Test boring at 21 places and core sampling were conducted during September-November 1998 along the ridge to the west of Hay Gulch and in the direction crossing the northwest of the drainage canal and National King Coal Mine (NKC coal mine). It was found that A layer which NKC coal mine is now drilling is the upper part of A coal seam where the seam bifurcates. The boundary to the west of the thick A coal seam is not clear, and there is a possibility that more reserve from the thick coal seam and single seam exists toward Cherry Creek. In the existing coal drilling area, the lower A seam existing under the upper A seam becomes thin rapidly, and the seam thickness becomes less than 1 foot. The average thickness of thick coal seams is 9.9 feet, and the area is 780 acres along the ridge. The upper A coal seam except the above is 5.5 feet in average seam thickness and 910 acres in area. The reserve is 23 million tons. As to the quality of thick coal seam, the average heating value is 7,089 kcal/kg, sulfur content 0.68%, and ash content 7.50%. As coal drilling conditions, the same level as or higher than those of NKC coal mine is expected. (NEDO)

This paper gives an outline of the structures of bats. Unlike birds, bats have a wing membrane structure. The membrane constituted of the skin is spread between five fingers to form the wing. The wing membrane is seen in the forelimbs and the tail. In the chest and the shoulder, the ligament sheet supports the muscles. The wing membrane is about 0.5mm in thickness, with a fiber net woven through reflecting a tension field in flying. The fiber net is composed of compound materials of elastin and collagen. The shoulder joints consists of the clavicle, scapula and humerus, which is close to human beings. The elbow joints rotate only inside the plane of the wings. The leg joints are hook-shaped, with the tendon sheath provided with ruggedness. The carpus is made up of eight bones and is characterized by the ability of spreading and storing the wings. At the time of storing the wing membrane, the finger joints are stored and, during the flight after the wings are spread, it forms the flapping wing plane. Lightweight and formation of the sturdy front edge are characteristics common to other flying creatures. The spreading and the storing are possible through the direct motion of the hands. The shoulder joints and the carpus of the human beings are closer to those of bats than to those of birds. (NEDO)

The survey was finished in the final fiscal year (FY 2000) of the Tanjung Enim IV Coal Exploration Project between Japan and Indonesia, and a report was summarized on the preliminary coal mining plan. In the design of the optimum mining area and pit, in terms of 3 cases of coal price of $8, $10, and $12/ton, the pit design was made considering rivers, houses, power transmission lines, etc., and the actual coal yield was asked. In the case of coal price of $8/ton, the actual coal yield in pit was 315 million tons in north block and 171 million tons in south block. In the case of coal price of $10/ton, pits are expandable in north block, but not in south block. For all the pit shapes designed, long-term mining plans were worked out. In each of the cases of coal production amount of 1 million, 3 million and 5 million tons, indicated were secular changes in overburden amount and coal quality because of the difference in mining direction. Further studies were made on the deposition plan, simulation of models of mining heavy machines, coal mine facilities, economical efficiency of coal mines, etc. (NEDO)

The use of a commercial jet transport airplane over its life of 20 years has been increasing because of intestified competition after cancellation of the regulations. It is necessary that users of the airplane adopt such a positive way as they themselves maintain safety of their airplanes rather than they wait for feedback or technical instructions from manufacturers. This paper outlines the points at issue regarding the problem of fatigue strength which is fundamental to the safety problem, explaining by various examples that the fatigue strength problem includes phenomena of which theoretical elucidation has not been obtained. Consequently, some points to be paid attention to are cited. For instance, in the analysis of reliability in case of determining the period for initial inspection (safety life), reliability should be 95-99% which have been advised by Boeing and others, even if confidence level is 95% as usual In case of considering a fleet number in the reliability analysis, the fleet number should be reflected by grouping significant in fatigue analysis. 30 refs., 10 figs., 1 tab.

The groundwater of the Mobara gas-field in Boso peninsula, eastern Japan, contains considerable amount, around 100 mg/L, of iodine besides dissolved methane. Twelve groundwater samples from gas-producing wells to the aquifer within the Kazusa Group in Mobara and Naruto districts have been analyzed for iodine, pH, Eh, HCO{sub 3}{sup -}, NH{sub 4}{sup +}, SiO{sub 2}(aq), {delta}D, {delta}{sup 18}O, {delta}{sup 13}C{sub CH4} and seventeen elements. There is a good correlation between the concentrations of the dissolved elements to those in marine algae. The principal source of the iodine is believed to be algae buried in the sediments and the iodine has been discharged to the porefluid during decomposition of the tissue. The molar ratio of I{sup -}/Cl{sup -} in the groundwater increases from 1.0 x 10{sup 3} to 2.2 x 10{sup 3} with changing the depth from 2000 to 1000 meters below the surface and turns to decrease from 2.2 x 10{sup 3} to 1.8 x 10{sup 3} with going up from 1000 to 500 meters. This tendency may be caused by the variation of buried organisms due to changing the sedimentary environment. The observed variation in the ratio indicates that the iodine discharged in the pore fluid did not migrate significantly after the deposition of the formation. This paper can be regarded as an English version of Japanese article written by Kamei, which was published on the 'Shigen Chishitsu (Resource Geology)' 51(2)145-151(2000). (author)

Due to the improvement of algorithm and the advancement of calculation performance, the imaging by depth migration before stacking is being put into practice from the viewpoint of both calculation cost and accuracy. A lot of imaging examples have been already reported from the survey areas with complicated velocity structures, such as the North Sea and the Gulf of Mexico. Effectiveness of the method has been confirmed. For imaging techniques in Japan National Oil Corporation and Japan Petroleum Exploration Co., Ltd., high-speed depth migration before stacking and high efficiency velocity structure estimation technique have been investigated. This paper describes necessary care to be taken when using depth focusing analysis (DFA) for correcting a velocity model, as an interim stage of case study. The results of depth migration before stacking using dip moveout (DMO) velocity were further inferior to the section obtained by the migration after tracking. Tendency of velocity errors was distinctly deviated with the variation of depth and horizontal position. It was not suitable for modifying the velocity model using DFA. 4 refs., 4 figs.

This paper describes the summary and result of magnetic exploration on the Kabutoyama volcano in the city of Nishinomiya, Hyogo Prefecture, Japan. It also states the interpretation and discussion on magnetic anomaly in the volcanic conduit of the mountain by using a three-dimensional magnetic structure model. Terrain surface magnetic exploration for the Kabutoyama volcano was performed by using six traverse lines each in different azimuths with the triangulation point at the summit as the basic point and by using a proton magnetometer. The exploration results of the six traverse lines around the Kabutoyama volcano may be generalized as follows: magnetic anomaly in the vicinity of the summit is moderate with little change, but it increases to 500 nT to 2,500 nT in the vicinity of the distances of 150 m to 200 m; a peak is formed with a width of a few tens of meters; and the magnetic anomaly showed a trend of rapidly decreasing at outer sides of the peak. The results of the magnetic exploration and the magnetization intensity measurement leads to a belief that such a magnetic anomalous band of an annular form would exist corresponding to the boundary or its vicinity of andesite and granite, and the Rokko granite having magnetization intensity as small as can be neglected would be distributed at outer sides of the boundary. The result of the three-dimensional magnetic structure model calculation, which assumes the internal structure of the magnetic structure to be non-uniformly magnetized, reproduced the magnetic anomaly patterns well as compared with the observation results. 1 ref., 5 figs.

This paper introduces features and trends of analyzing performance and construction of automotive tires. Tires are demanded of high durability, high motion performance, good comfort performance for vibration and noise, and low fuel consumption performance. A feature of analyzing the construction is to execute a modelling assuming that a tire has air-rigid flexible structure and rubber materials show hyperelastic behavior, hypothesizing a strain energy density function. In addition, a tire is highly incompressible. Visco elasticity and anti-friction performance are also important points. Rubber and cord layers have elastic characteristic of three-dimensional perpendicular anisotropy as well as non-linearity with which characteristics change according to transformation. A structural analysis must cover from static analysis to steady dynamic analysis, non-steady dynamic analysis, and eigenvalue analysis. Thermal analysis of tires simulates phenomena by combining dynamical analysis with thermal analysis. Super-computers have now come to be used for formulating equilibrium equations using finite element methods, developing finite elements, and performing heat or visco elasticity analysis and applied analysis. 35 refs., 3 figs.

With respect to a velocity model structuring method using depth focusing analysis (DFA) as a depth image processing technology used for elastic wave exploration, its practicability was discussed. First, synthetic data were used to extract problems in the DFA. The problems were extracted by using a model with constant velocity as an initial model, deciding on the sequential structures from the higher order, and estimating velocity and depth of each layer by using a model fitting type method. In its application to field data, characteristic records include those for rock salt beds distributed in a sheet form and the folding structure associated with the growth thereof, as acquired in offshore seismic exploration carried out in the eastern part of Gulf of Mexico. The conclusion is that the DFA is a method that can derive a velocity model with required accuracy by using a minimum number of repetition even against relatively complex structures. Particularly, the quick convergence from the initial model with a constant velocity until a certain accuracy is reached is a noteworthy advantage. 3 refs., 6 figs.

Discussed in this paper are the P-wave and S-wave zero-offset VSPs carried out utilizing boreholes located in Nada Ward, Kobe City, and Hokudan-cho, Hyogo Prefecture, as part of the deep layer boring survey following Hanshin Earthquake Disaster. This effort aims at the elucidation of P-wave and S-wave velocity structures, high-precision identification of data obtained by the surface reflection method, and collection of basic data for active faults investigation in the future. Among the velocity structures obtained for various layers, the S-wave velocity structures in particular agree with the stratigraphy excellently and may be utilized in seismic analyses to be conducted in the future. Reflection from geological boundaries is received with precision, providing accurate information about correlation between reflection and geological cross sections. The records will be useful in formulating plans for reflection surveys for instance of the boundary between the Osaka group and Kobe group. Generally speaking, reflection coefficients are large when the reflection is from a boundary where difference is great in elastic wave impedance (mainly difference in velocity). In the case of the boundary between the Kobe group and granite in Awaji Island, however, no strong reflection is found despite the great difference in velocity. This is attributed to the complicated, sharp inclination of the basement rock and to its weathering. 4 refs., 8 figs.

Akita-Yakeyama is a Quaternary volcano located in the north-western part of the Sengan geothermal area. Geothermal resource surveys have been performed from the middle of the 1970s in the Sengan geothermal area, and the Sumikawa geothermal power plant started its operation in 1995. By the analysis, the magnetic basement depth became lower in the north of Yakeyama body. However, the distribution including low magnetic anomaly in the south of Yakeyama body could not be explained only by a simple magnetic structure model. In this study, the magnetic anomaly in this area was analyzed in detail, and a construction of the magnetic structure model was intended by taking borehole data into account. The low magnetic intensity zone with low amplitude agreed well with the geothermal alteration zone. The high magnetic intensity zone and the low magnetic intensity zone corresponded with the distributions of volcanic rocks magnetized normally and reversely, respectively. Kakkonda and Matsukawa geothermal power plants were located in the distinct low magnetic intensity zones. There was a low magnetic intensity zone with long wave length over the whole Sengan geothermal area. A high magnetic intensity zone was observed in the northern foot of this area. From the magnetic measurements of borehole sample rocks, this was found to correspond with the newly formed granite body. 9 refs., 4 figs.

The technology trend was surveyed to clarify the themes of smart structural system towards its R and D. The smart structural system is a structural system which incorporates functions of perception, judgment and learning by integrating functions, structures and information, to ensure the structural soundness at real time and control the active-adaptive of shapes. The final goal of it is to make materials and structures similar to organic systems. It has a self-repair function which can detect the generation and propagation of cracks and prevent the destruction positively with conducting self-diagnosis. High performance, high efficiency and energy saving are expected by combining the conversion of design concept into destruction control and the regulation of vibration, noise and shape. Especially, it is effective for the safety of aerospace systems, earthquake disaster measures, and extension of machine life. This report describes the background, purpose, R and D activities in Japan and foreign countries, and basic development themes. In addition, it arranges the needs of various industrial fields systematically, and proposes a concrete concept. Furthermore, the effects expected by the application of smart structural systems and the outline of international technical cooperation are presented. 110 refs., 164 figs., 19 tabs.

Increased dialogue between NADOs and academics – challenges and possibilities

DEFF Research Database (Denmark)

Gleaves, John; Christiansen, Ask Vest

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...

The Nishino Breathing Method and Ki-energy (Life-energy): A Challenge to Traditional Scientific Thinking

Science.gov (United States)

Ohnishi, S. Tsuyoshi; Ohnishi, Tomoko

The breathing method, which was developed and is being taught by Kozo Nishino, a Japanese Ki-expert, is for raising the levels of Ki-energy (life-energy or the vitality) of an individual. It is neither a therapy nor a healing technique. However, many of his students have experienced an improvement in their health, and in some cases, they were able to overcome health problems by themselves. Since this is an interesting subject from the standpoint of complementary and alternative medicine (CAM), we have been collaborating with Nishino to conduct a scientific investigation of his Ki-energy. We found that Nishino's Ki-energy can inhibit cell division of cancer cells, protect isolated mitochondria from heat deterioration and reduce lipid peroxidation in heat-treated mitochondria. Although Ki-energy may consist of several different energy forms, we found that at least one of them is near-infrared radiation between the wavelength range of 0.8 and 2.7 µm. Another interesting observation at his school is the Taiki-practice (paired Ki-practice). During this practice, Nishino can ‘move’ his students without any physical contact. Many of them run, jump or roll on the floor when they receive his Ki-energy. We studied this and propose that ‘information’ is conveyed through the air between two individuals by Ki-energy. This may be called a five sense-independent, life-to-life communication by Ki. All of our results suggest that we should re-evaluate the Cartesian dualism (separation of mind and body) which has been a fundamental principle of modern science for the past three centuries.

A policy of improving a very large floating body was planned based on its dynamic characteristics, and a proposal was made thereon. Furthermore, discussions were given on stability that considers effect of elastic deformation required when a structure is mounted on a floating body. With respect to a structural design of a very large floating body in which elastic response is governing, and upon modeling the very large floating body into an aeolotropic plate on an elastic supporting floor, it was shown that the existing range of natural vibration speed in the elastic response is in higher range than the natural vibration speed of heave. It was also indicated that the peak height of response to waves in resonance is inversely proportional to wave frequency, and furthermore, degree of flowing in of vibration energy during the resonance is determined by an inner product of spatial vibration patterns of wave force and the excited mode shape. A proposal was made on a floating body improved of excessive response in the floating body edges by changing the characteristics of the floating body edges. In addition, discussions were given on stability that considers elastic deformation of a floating body that becomes necessary when a structure, such as a building, is built on a very large floating body. 9 refs., 9 figs., 3 tabs.

The structure of steel-concrete hybrid structure which is recently attracting attention is outlined quoting some examples. The effects of steel-concrete hybrid structure are classified according to the characteristics. The Normandie Bridge completed in January this year near the mouth of the Seine River in France is a cable stayed bridge with the world largest span, and it has a hybrid structure of ingeniously combined steel and concrete. The Dole Bridge in France is a hybrid bridge with 7 continuous spans having steel corrugated sheets in the web. Hybrid structure has come to be applied to many structures other than the superstructure works of bridges. The substructures of bridges are applied to immersed tunnels, and the usefulness has come to be recognized widely. The features of hybrid structure can contribute well to the reinforcement of existing structures. In addition, adoption of hybrid structure has been studied as the best method for repairing and reinforcing structures damaged by earthquakes. 8 refs., 6 figs., 1 tab.

Neurobiología de la impulsividad y los trastornos de la conducta alimentaria*

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.

Fullerene (C60) and carbon nanotubes are expected as new carbon structures. This article describes the observation results of C60 and carbon nanotubes by means of STM (scanning tunnel microscope). The STM images of C60 thin films are illustrated, which have been obtained by annealing at 290 centigrade. It was confirmed that C60 monomolecular thin films are formed which conform to the substrate and have high regularity. The step height of C60 monomolecular thin films coincided with the step height of Cu (111) plane, which suggested that the step of films is reflected in that of Cu substrate. For the STM images under bias voltages, various images of C60 with three-fold axis of symmetry were observed. On the other hand, from STM observation of carbon nanotubes with diameter of about 30 nm which were separated and purified from the cathode deposits during the preparation process of C60, it was found that they have concentric multilayer structure. 18 refs., 7 figs.

Recently various studies have been conducted concerning the state changes of materials obtained through mechanical alloying (MA) or mechano-chemical (MC) processing. What is noticeable is the quasi-steady state of almost all the materials obtained through various processes including MA and MC, and that the super cooling, supersaturating and high residue distortion realized under unbalanced conditions have not been clarified. In other words, the tracing capability to the external binding conditions is low. In this report, the appearance of the high temperature phase and high pressure phase obtained through MA or MC processing, the forming of amorphous, the mesomerism of the amorphous materials, the interesting phenomena generated by combination between the mechanical disturbance and chemical reactions were discussed with concrete examples, and a steady dissipative organization theory was approached from the viewpoint of dissipative structure development which is equal to the forming process of the quasi-steady phase. 34 refs., 2 figs.

A tensor type CSMT method (STRATAGEM) was introduced for the purpose of investigating shallow subsurface, and a field test has been carried out thereon. This system consists of a transmission section, and a sensor section and a data acquisition and processing section to observe waveforms in a responsive electromagnetic field. The signal source is a semi-circular air loop with a radius of a little smaller than 2 m. The measuring points were selected at locations about 200 m apart from the signal source to measure two electric field components and two magnetic field components by using sensors installed on the ground surface. The field test was performed at the Yutsubo area in Oita Prefecture, Japan. The electric field dipole is basically 5 m long, while S and E lines are 10 m long. The measurement frequency ranges from 96 kHz to 1000 kHz. The measurement time was about five minutes, and the whole measurement work including apparatus set-up and withdrawal was completed in about 15 minutes to minimize interference with the field which is a meadow. The field test result revealed that resistivity profile in shallow subsurface can be obtained much more easily than with the conventional CSMT method. 2 refs., 10 figs.

Particle collisions near a three-dimensional warped AdS black hole

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.

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.

It has been 30 years since a conception structurally optimized design method'' was advocated as a new structural design system which links three factors; mathematical programming, a finite element method, and computers. This paper summarizes the current states in the optimizing technologies in Japan and views over their future, with reference mainly to the two symposiums held in the past as an activity of the subcommittee for structural system optimization in the Japan Society of Civil Engineers. The summary covers the following matters: Optimizing algorithms for structural designs, fuzzy theories, practical use of expert systems and AI, maintenance and management systems for structures, vibration control, shock resistant designs, inverse problems and structure identifying problems, and designs of underground and off-shore structures. For instance, examples of bridge designs include a minimum mass design on a pedestrians' bridge incorporating vibration sensitivities into restricting conditions, comparisons of economics in suspension bridges using a multi-stage determination method, and many others. Optimizing technologies are believed to advance greatly in the future and be used as a very routine design tool. 145 refs., 1 fig., 3 tabs.

This paper describes the following matters as one example of structural coloring of non-motional nature on the coloring mechanism in wings of Morpho sulkouskyi butterfly: The structure of scales on butterfly wings may be modelled into such a structure of a right angle frame of reference having a cyclic arrangement (with an interval of 0.7 [mu]m) of a zigzagged protrusion in the 'x' direction called a ridge (with a height of 1.8 [mu]m and a width of 0.54 [mu]m, the shape not changing in the 'y' direction), and having a plurality of protrusions of a ridge form called lamella in the 'z' (height) direction. A simple multi-layered thin film model was assumed that has lamella layers and air layers laminated alternately in the 'z' direction. The model was used to calculate reflection spectra on vertically incident light based on thickness and refractive index of material layers determined by a structural analysis of the scales. The result was considerably close to the reflection spectra of scales measured by using a microscopic spectrophotometer when the number of layers is set to six. The paper describes briefly examples of motility structural coloring (skin cells of rainbow color in tropical fish). 7 refs., 12 figs.

However, little is known about the nutritional status in non-COPD aging men with smoking history. We therefore investigated whether reduced lung function is associated with lower blood markers of nutritional status in those men.Subjects and methods: This association was examined in a cross-sectional study of 65 Japanese male current or former smokers aged 50 to 80 years: 48 without COPD (non-COPD group, divided into tertiles according to forced expiratory volume in one second as percent of forced vital capacity (FEV1/FVC, and 17 with COPD (COPD group.Results: After adjustment for potential confounders, lower FEV1/FVC was significantly associated with lower red blood cell count (RBCc, hemoglobin, and total protein (TP; not with total energy intake. The difference in adjusted RBCc and TP among the non-COPD group tertiles was greater than that between the bottom tertile in the non-COPD group and the COPD group.Conclusion: In non-COPD aging men with smoking history, trends toward reduced nutritional status and anemia may independently emerge in blood components along with decreased lung function

Mathematical structure of a vessel arrangement program was discussed in order to learn roles of container ships in ocean transport systems among China, NIES/ASEAN countries and Japan. Formulation is possible on a mathematical handling method for sailing route connection diagrams between ports, a transport network to indicate container movements, a service network to indicate sailing routes, and a network generalizing them. This paper describes an analysis made on the container transport system between Japan and China, taken as an example. Four ports were selected each from Japan and China, and the statistical database for fiscals 1996 and 1994 was utilized to set models for: (a) the liner network system with transshipment at the port of Shanghai and (b) the cruising route system going through the ports of Yokohama, Nagoya and Kobe. A hypothesis was set that a consortium (coordinated ship allocation) can be implemented ideally and completely. The transport network (a) is lower by 10% in total cost than the transport network (b), resulting in 1.6 times greater productivity. Actual service network is closer to the network (b), but the system can be utilized for discussing guidelines on vessel arrangement programs with which shipping companies pursue better management efficiency under a condition that the consortium can be formed. 10 refs., 6 figs., 2 tabs.

Three typical Japanese coals of non-coking coal, coking coal and anthracite were heat-treated with KOH, and change in their pore structure was examined by absorption of N2, X-ray diffraction and TEM observation. In addition, the relation between a coal rank and pore structure was also studied by absorption experiment of N2. In experiment, the mixture of coal and KOH in a nickel holder was heat-treated in N2 gas flow at heating rate of 2{degree}C/min, and held at a fixed temperature for one hour. To clarify the pore structure, N2 absorption isotherms were measured at -196{degree}C under nearly 76cmHg using a commercially available full-automatic absorption measurement equipment. Based on the X-ray diffraction and TEM observation results on activated coals, the relation between the N2 absorption and pore structure was studied. The results are summarized as follows: (1) The yield and absorption ability of coals increase with a coal rank, (2) The specific surface area of coals reaches its peak at 800{degree}C in activation temperature regardless of a coal rank, and (3) The activation behavior of coals is dependent on a coal rank. 5 refs., 7 figs., 1 tab.

In the second continuous casting line of Kure Iron Works, Nisshin Steel Co., Ltd. improvement of the continuous casting counts per tundish was attempted for a target of max. 20. The results are as follows: (1) Non-SiO{sub 2} conversion of material for the long nozzle immersed part: About 20% improvement of durability compared with a conventional material to clear 0.059 mm/min of the targeted erosion speed when 20 CCC/TD is realized, (2) Durability improvement of SN plate: About 20% durability improvement was attained compared with a conventional material by the adoption of a non-SiO{sub 2} material, (3) Erosion resistance improvement of the immersed nozzle slug line part: Castable period was extended to 1 ch life improvement by increasing zirconia content, (4) Rise of stopper full open position: The rise of the full open position produced less variation of melt level than the conventional structure without increase of the SN opening, enabling plugging prevention between the stopper head and the upper nozzle which was an objective of this improvement, (5) Structure improvement of the upper nozzle: This improvement successfully prevented leaks from damage of the casting stop nozzle metal case and enabled casting under low gas flow even in TD nozzle plugging. These improvements gave a possibility to achieve max. 20 CCC/TD. (NEDO)

The coherent structure and relevant heat transport in geostrophic flows under various density stratification has been studied by using both direct numerical simulation and rapid distortion theory. It is found that in a neutrally stratified flow under system rotation, the temperature fluctuations become very close to two-dimensional and their variation is very small in the direction parallel to the axis of rotation. Under the stable stratification, the velocity and temperature fluctuations tend to oscillate with the Brunt-Vaisala frequency. Under the unstable stratification, on the other hand, vortex columns are formed in the direction parallel to the axis of rotation. However, the generation of the elongated vortex columns cannot be predicted by the rapid distortion theory. The non-linear term is required to generate these characteristic vortex columns. 11 refs., 18 figs., 1 tab.

Spontaneous potential (SP) was measured on the known traverse line of resistivity structure crossing Hanaori fault in Ohara area, Kyoto city to observe change in SP around the fault and to examine the possibility of fault position exploration. The supposed causes of generation of SP are as follows: the existence of sulfide mineral deposit including polarized minerals, underground fluid flow, and the existence of stratum including chemical compositions from hot springs. The SP method estimates underground structures based on measured surface potential distributions using DC component under anomaly of SP. FEM modeling clarified that a fault fracture zone is one of the causes of generation of SP, by considering SP measurement and resistivity structure strongly affecting observed SP. Consequently, combination of SP measurement with resistivity structure exploration allows a reliable fault estimation method. Under the assumption that anomaly of SP is caused by polarization around fault, the horizontal dipole model based on polarization of current source dipole along fault can well explain the measured data. 2 refs., 6 figs.

The magnetic structure in Hokkaido was quantitatively analyzed by the magnetic anomaly distribution. This paper describes its characteristics. Detection of structural boundaries and 3-D analysis of double-layer structure were conducted for the regional magnetic data in a region with about 500 km square. There was not so large difference in patterns of magnetic anomaly distribution between the case that the direction of magnetization was set at 45{degree} to the west during the geomagnetic conversion according to Segawa and Oshima and the case that it was set as same as the current geomagnetic direction. The method of Blakely and Simpson was useful to detect the boundaries of magnetic structures. The structural boundaries obtained were more linear than the iso-magnetic contour lines. A new method has been conceived in which the approximation of 3-D magnetic structure analysis can be deduced, and the irregularity of magnetic basement can be determined by the repeated calculation. In practice, this method was applied to the magnetic data in the whole Hokkaido. The calculation was stably converged. It was found that the magnetic structure obtained in the Kamuikotan/Ishikari-Kitakami magnetic belt exhibited a fault structure having steep slopes accompanied by the basin structure in the western boundaries. 19 refs., 6 figs.

Large deformation of the crust is generated by relatively large displacement of the mediums on both sides along a fault. In the conventional finite element method, faults are dealt with by special elements which are called joint elements, but joint elements, elements microscopic in width, generate numerical instability if large shear displacement is given. Therefore, by introducing the master slave (MO) method used for contact analysis in the metal processing field, developed was a large deformation simulator for analyzing diastrophism including large displacement along the fault. Analysis examples were shown in case the upper basement and lower basement were relatively dislocated with the fault as a boundary. The bottom surface and right end boundary of the lower basement are fixed boundaries. The left end boundary of the lower basement is fixed, and to the left end boundary of the upper basement, the horizontal speed, 3{times}10{sup -7}m/s, was given. In accordance with the horizontal movement of the upper basement, the boundary surface largely deformed. Stress is almost at right angles at the boundary surface. As to the analysis of faults by the MO method, it has been used for a single simple fault, but should be spread to lots of faults in the future. 13 refs., 2 figs.

Design considerations such as design schemes, the assemblage and welding of steel plates, and safety for fatigue of welded connections have to be taken for the cable anchorages of the steel cable stayed bridges. In this study, two full scale models, which have different shape of box anchorages welded to the web of the main girder, were made to investigate fatigue characteristics as well as assemblage of plate and gelding details. Finite element analyses for both test models and actual bridges here carried out to compare stress distribution. It was confirmed that the assemblage and welding of both types of box anchorage were attainable kith required quality and accuracy. According to the fatigue test, fatigue cracks originated from the weldings of the bearing plate to which the load from cable socket applied directly were caused by out-of-plane bending of the bearing plate. It was proved that the slight modifications of the details around the bearing plate resulted in sufficient fatigue strength in both types of anchorage. 1 ref., 23 figs., 2 tabs.

Structure of non-equilibrium cesium seeded argon plasma excited with microwave power is simulated numerically. The plasmas produced at suitable microwave powers are found to consist of three regimes, that is, the region limited by charged particle loss toward the wall, the full seed ionization and the diffusion limited regions. The fully ionized seed plasma is produced within the skin-depth determined by the electrical conductivity of the plasma, and the thickness of the fully ionized seed plasma depends on the seed fractions gas pressure and microwave power. 15 refs., 6 figs.

Change in structures of 3 kinds of coals with different coal ranks and their deashed coals was studied by heat treatment below 200{degree}C. In experiment, crushed Adaro, Taiheiyo and Huaibei coals below 200mesh and their deashed coals were used as specimens. The coal and deashed coal specimens dried in vacuum at 110{degree}C for 3 hours were filled into an autoclave, and the heat-treated coal specimens were prepared by holding them under initial nitrogen pressure of 2kg/cm{sup 2} at a fixed temperature for 30min. Extraction using pyridine as solvent, volumetric swelling using methanol or benzene as solvent, and measurement of the amount of carboxyl and phenolic hydroxyl functional groups were conducted for these coal specimens. The experimental results are as follows. Huaibei coal has developed aromatic ring structure, and its structure is hardly affected by heat treatment. The oxygen containing functional groups decrease by heat treatment over 100{degree}C in Adaro coal and 150{degree}C in Taiheiyo coal, and PS, MQ and BQ also decrease due to aggregation between molecules. 5 refs., 2 figs.

In order to investigate in detail structures of the fractured fault band, the VSP tests were conducted using a 750m deep borehole penetrating the Nojima fault in Awaji Island. The borehole penetrates the fault clay band at a depth of 624m in the Hirabayashi area. The offset VSP survey, conducted by the aid of hydrophone through the naked borehole, detects many characteristic phenomena resulting from the fault fracture. Largely fractured lithofacies are found by the core observation at a depth in a range from 557 to 673m. P-waves propagate at 4.6 and 5.1km/s above and below the fractured band, respectively. The fractured band is subdivided into 2 sections, both being of low speed of 4.5 and 3.1km/s. The X1 and X2 phases resulting from the fault fracture are also observed, above and below the fractured band. The causes for these wave phases are now under investigation. 4 figs.

As observation results on the time-dependent change in the ring-opening reaction of novolac epoxy resin with acetic acid by MALDI-TOFMS, the epoxy ring was opened with reaction time, the hydroxy group formed by the ring-opening reaction was acetylated, those components were measured. In the case of the FABMS/MS observation of materials and the reaction products, the estimation structure could be confirmed from the measured results of MALDI-TOFMS. In the polymerization of bisphenol A epoxy resin with N, N`-dimethylethylenediamine, it was observed by MALDI-TOFMS that many kinds of polymers with high molecular weight were formed with an increase of reaction time. In this case, the LSIMS/MS observation of materials and the reaction products was carried out, the estimation structure could be confirmed from the measured results of MALDI-TOFMS. 19 refs., 8 figs.

An analysis method in which the technique of a vehicle obtained when a three-dimensional singular point distribution method and Kagemoto`s mutual interaction theory are combined was expanded for the fluid area was proposed as the structural analysis of very large semi-submersibles in waves. A partial structure method is used for the structure. In a fluid area, the number of unknown quantities appearing in a final expression could be largely reduced by introducing the new concept of a group body. In this process, both hydro-elasticity and hydrodynamic mutual interaction are considered. As a result, floating bodies that could not be previously calculated can be modeled as a three-dimensional frame structure and the response analysis in waves can be carried out without damaging the accuracy. The calculation result is used as the input data required for analyzing the structural fatigue locally during structural design of very large semi-submersibles in the 3,000 (m) class. This study can present a series of procedures between the response analysis of very large floating bodies in waves and the structural design. 11 refs., 14 figs., 1 tab.

The kernel function for transient vertical magnetic dipole was defined for semi-infinite uniform medium, and the 1-D imaging algorithm by TDEM (time-domain electromagnetic) method was developed for underground resistivity structure. Electromagnetic migration method directly images sectional resistivity profiles from the data observed by frequency-domain MT method, and determines underground resistivity profiles by integral equation of MT field using the concept of return travel time in reflection seismic exploration. The method reported in this paper is also one of the EM migration methods. The imaging algorithm of 2-D resistivity structure was developed by correcting 1-D imaging in consideration of the effect of 2-D anomaly on 1-D imaging (the resistivity of anomaly can be obtained from the resistivity contrast between anomaly and medium). The conventional methods require enormous forward computation, while this method can obtain underground resistivity structure in extremely short computation time, resulting in superior practicability. 12 refs., 7 figs.

The structure of poly({beta}-alanine) polymerized in the solid state was studied. This polymerization was carried out on a single crystal of {beta}-alanine at 170 centigrade for 40 h in an evacuated tube. The crystal structure of the polymer was assigned to I-type crystal of Nylon 3. The polymer chains were oriented vertical to the crystal side and different to monomer crystal orientation. This may be caused by the molecular layer slipping along the cleavage plane of monomer crystal. A scanning electron microscope(SEM) showed the band structure of hundreds nm width of same orientation, but X ray showed only unoriented rings, so that they are estimated to be the structure of fine fibril like assembly or necklace like continuous chain structure of grains. Near the surface, whiskers which were thought to be oligomer of low degree of polymerization, were observed. The SEM of end view of the etched surface did not show the laminated structure but showed the network structure of about 1 mu-m which is thought to be fibril precursor. 12 refs., 10 figs.

Three dimensional structure of seismic wave velocity for the crest and upper mantle under the North East Japan is determined by the seismic tomography which is prepared by the natural earthquakes confirmed by the observation network for micro earthquakes, indicating that the low velocity region exists just under the corresponding volcano to the upper mantle. Further, the following contents can be verified: Any micro earthquakes which are verified by the above observation network and occur at the depth of 25-40km show the lower generation rate less than 1% and the low dominant frequency compared with the conventional inland earthquake(lower limit of depth is 15km) in the same region and occur around volcanos. The existence of the remarkable reflection surface for S wave which is found at the depth of 10-20km seems to be caused by the melting mass. The above mentioned low velocity region is estimated to correspond to the lifting region of high temperature magma, micro earthquakes of low frequency to the magma activity around that magma and the reflection surface for S wave to the part of the magma. 8 refs., 4 figs.

Parameters are analyzed to provide data for deciding, in the planning and designing stages, whether a cable stayed bridge or an extradosed bridge should be adopted. Comparative investigation of the vibration properties of both types of bridges is also referred to. The result of the study on the structural properties of the cable stayed road bridge and the extradosed road bridge is introduced. Based on the concept of the extradosed bridge, designers are now able to select without restraint the after load sharing rate of the diagonal members. Parameter analysis of a diagonal member reinforced 3-span continuous beam is performed. By introducing indices showing the load sharing rate of the diagonal member, the cable stayed bridge can be distinguished logically from the extradosed bridge in designing. It is found important that the height of the main tower is set to approximately 10% the length of the center span for the construction of the extradosed bridge. The vibration properties of the cable stayed bridge and the extradosed bridge of the same scale are compared. 7 refs., 18 figs., 6 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.

Through the hydrogenolysis of Wandoan coal and Tanito Harum coal which are used for the NEDOL process, differences of liquefaction characteristics between them were found. The purpose of this study is to grasp these differences as differences of chemical structures of oil fractions. The compound type analysis was conducted for oil fractions obtained at varied reaction temperature for varied reaction time. Coal liquefaction characteristics of these coals were discussed by relating oil yields and chemical structures. For Tanito Harum coal, yields of gas and oil were considered to be lower than those for Wandoan coal, which reflected that the contents of partially hydrogenated hydroaromatics in oil fraction from the former were lower than those from the latter, and that the remarkable change of composition did not occur with the progress of the reaction. For both the coals, the remarkable changes in the average molecular weight of oil fraction were not observed with the progress of the reaction. While, the content of methane gradually increased with the progress of the reaction, which suggested that oil was gradually dealkylated. 5 figs.

Large ultrafast optical nonlinearities in conjugated polymers have attracted much attention because of possible applications to nonlinear optical devices. One-dimensional systems such as conjugated polymers have localized excited states with geometrical relaxation. In this study, photoexcited states in polydiacetylene has been investigated by femtosecond Raman gain spectroscopy with 300-fs resolution. A new photoinduced Raman peak with lifetime of 1.5 ps has been observed at 1200cm{sup -1} for the first time. This peak indicates acetylene-like structure of the main chain relaxes to butatriene-like structure due to the formation of self-trapped exciting with the geometrical relaxation. The formation and decay kinetics of the Raman signals is consistent with the relaxation processes of exciting observed by femtosecond absorption spectroscopy. 8 refs., 5 figs.

The purpose of this study is to combine seismic activity and volcanic activity by reproducing the formation process of the crustal structure from a physical viewpoint or developing as its extension a numerical simulator which can predict the future. The phenomenon to which attention is especially paid at present is a relation between the dynamic process and the thermal process in the domain including the crust or the upper mantle. Namely, to elucidate the formation process of the crust structure, diastrophism also including seismic activity, igneous activity, etc., it is important to evaluate effects of the behavior of heat supplied from the deep on the dynamic process. In the finite element method, it is not easy to make the effect of gravity reflect to the calculation for boundary conditions. Accordingly, it is general to pay attention to stress difference, considering that stress by gravity is in proportion to static rock pressure stress. Further, to realize interaction between the thermal process and the dynamic process, effects of thermal stress are expressed combining the heat conducting analysis and the plastic flow analysis. 3 refs., 7 figs.

Restructuring was carried out on a sedimentary basin structure model of the Osaka plain including Osaka Bay by using newly obtained underground structural data. After the Hygoken-nanbu Earthquake of 1995, a large number of underground structure investigations have been performed in Osaka Bay and urban areas of Kobe and Osaka. However, very few surveys have been done in areas peripheral to Osaka Prefecture, such as the Ikoma area. Therefore, an attempt has been made to increase the number of measuring points to acquire underground structural data of these areas. Estimation of basic rock depths has utilized the dominant cycles in H/V spectra obtained from micro vibration survey, and good correlation of the base rock depths derived by a refraction exploration and a deep-bed boring investigation. With regard to bed division and P- and S- wave velocities in sedimentary beds in the Osaka sedimentary basin, an underground structure model was prepared, which was divided into four beds according to the refraction exploration and the micro vibration investigation. Data obtained by using this model agreed well with depth data acquired from physical exploration and other types of investigations. However, no good agreement was recognized in the data for such areas where the basic depth changes abruptly as the Rokko fault and the Osaka bay fault. 6 refs., 8 figs., 2 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.

Participaram da pesquisa 47 atletas do sexo feminino de alguns esportes estéticos (ginástica artística, nado sincronizado e saltos ornamentais, com idade entre 12 e 16 anos. Para avaliar o comportamento alimentar de risco para transtornos alimentares (TA, a insatisfação corporal e o GCPE foram utilizados o Eating Attitudes Test (EAT-26, o Body Shape Questionnaire (BSQ e a Commitment Exercise Scale (CES, respectivamente. Dobras cutâneas foram aferidas para o cálculo do percentual de gordura das atletas. Os resultados apontaram associação significativa entre a insatisfação corporal e o comportamento alimentar (p<0,05, assim como entre o GCPE e o comportamento alimentar de risco para TA (p<0,05. A partir da regressão linear múltipla, todas as variáveis, com exceção do percentual de gordura, demonstraram influências sobre o comportamento alimentar de jovens atletas. Este mesmo teste também apontou influências do percentual de gordura e da insatisfação corporal sobre os escores da CES. Concluiu-se que a insatisfação corporal e o GCPE foram fatores predisponentes para o comportamento alimentar de risco em atletas de esportes estéticos.

Once cajas de cartón se fueron llenando de negativos por el fotógrafo con sede en Ra- mala Garo Kuftedjian, en su Studio Venus. Después de su muerte su familia las cedió al municipio. Los negativos representan tanto personas solas como familias completas, a menudo con motivo de un evento particular: un matrimonio, la llegada de un nuevo bebé o un viaje. Fotografías familiares que se uti- lizan como testimonios de la integridad de la familia; los ausentes se hacen presentes por medio de una fotografía que muestra uno de sus parientes. Mientras que las fotografías muestran las di- ferencias en las relaciones sociales y los cam- bios en la moda, los documentos de archivo se re eren a períodos concretos de la historia palestina: la época bajo dominio jordano, la administración por las fuerzas de ocupación israelíes y el período posterior a los Acuerdos de Oslo, así como la creación de la Autoridad Palestina en Cisjordania y la Franja de Gaza. Finalmente, las fotografías de la ciudad en- focan elementos para la reorganización de la existencia colectiva e individual. Una de las condiciones principales es la falta de espa- cio.

A concept of a system is constructed in which a series of the flow from the construction of structures to the shape and control in structural phase, repair, and dismantlement is made effective and controllable by giving a function of intelligent structure to structural systems in aerospace/architecture/civil engineering fields. For it, fundamental technologies required for the systems were extracted for construction of the technology system. Further, in relation to the intelligent machinery system including the control method, manipulation, and communication of the structure under the micro-gravity environment required for this system, the basic experiment was conducted at the ground gravity-free experimental center to acquire the effective data. As to the base technology, three fields were studied of the intelligent machinery system including the behavior/control of materials and structure, intelligent robot, and communication. In the experiment on micro-gravity environment, experiments were carried out on the behavior of micro-gravity rover for small planetary probe, inter-satellite group communication, capture of trouble-satellite, development of inflatable structure, and hopping robot. The valuable data were obtained. (NEDO)

In order to obtain knowledge about formation and growth of condensed ring structure in a coalification process, discussions were given on product skeleton structure by using hydrogenation and hydrocracking of heated cellulose. In underwater heating of cellulose, reaction of dehydration has occurred at 200{degree}C or lower, that of decarbonation at 250{degree}C or higher, and that of demethanizing at 300{degree}C, resulting in production of a dark-brown coal-like substance. The substance has lower H/C value and higher O/C value than coal. As the underwater heating temperature rises, the hydrogenation reactivity of the heated substance decreases, and so does the ratio of conversion into toluene solubles. These phenomena are related to strength of cross-linking bond between unit skeleton structures. A substance heated at an underwater heating temperature of 200{degree}C turns toluene-soluble almost completely even during the hydrogenation reaction (350{degree}C for 2 hours), but the soluble product decreases at underwater heating temperatures of 250 and 300{degree}C. However, soluble product of more than 90% was obtained when hydrocracking (at 425{degree}C for one hour) was performed. The toluene-soluble product in the heated substance is only 50% when the underwater heating temperature reaches 350{degree}C even if the hydrocracking is carried out. 3 refs., 5 figs.

Since a huge amount of coal containing inorganic ash is treated for the commercial hydroliquefaction process, cheap catalysts widely distributing on the earth with large reserves are desired rather than expensive catalysts. This paper describes the effects of addition of sulfur on the catalysis of iron sulfates during the hydroconversion of 1-methylnaphthalene (1-MN). Reactions of 1-MN were conducted at the same charging amount of iron in the reaction system. Sulfur was directly added in the reaction system using ferrous sulfate (FeSO4) as precursor. Consequently, it was found that FeSO4 provides lower but similar catalytic activity to the synthetic pyrite catalyst prepared through the complex processes with the precise control. Thus, it was revealed that high performance pyrrhotite (Fe(1-x)S) catalyst can be prepared for the hydrogenation of aromatic-rings by adding solid sulfur into the reaction system using commercial reagent, FeSO4 as a precursor of the catalyst. 9 figs.

To evaluate the risk during longevity of reinforced concrete structure subjected to earthquake motions, called lifetime risk, damage and safety were estimated by means of the earthquake risk analysis and earthquake response analysis. For the earthquake risk analysis, historical earthquake data with relatively low accuracy were efficiently taken into account, to determine the annual mean generation probability against the earthquake motion strength in ten main cities. A new damage index with load hysteresis was defined as an anti-earthquake evaluation index where accumulative damage is taken into consideration. Assuming that the damage transits from `certain state` to `certain state` every time the earthquake motion generates at the noticeable place, damage transition matrix expressing transition probability was calculated by using the results of earthquake risk analysis and the accumulative damage index. The lifetime risk was calculated from the damage transition matrix and the earthquake motion generation probability, to evaluate the safety. 21 refs., 10 figs., 8 tabs.

MT measurement of transects was made in the central part of North-Eastern Japan Arc to clarify tectonics of subduction zones. 1-D, 2-D and 3-D resistivity structures are observed in surface layers, and zones shallower and deeper than a Conrad surface, respectively. A main structure direction is S-N or NNE-SSW. Ishinomaki-Chokai tectonic line and low- resistivity zones due to Quaternary volcanos (Naruko, Onikobe) exist in a backbone range region. Resistivity is 100{Omega}{center_dot}m or less by Bostick Inversion except Mesozoic and Palaeozoic layers in the southern Kitakami mountainous region, resulting in a good agreement with previous results in a north transect. Resistivity is several {Omega}{center_dot}m and depth is several km around Shinjo basin and in surface layers of Kitakami River region. The backbone range region shows complex resistivity structures because of volcanic activity and wide-area hot water activity. High-resistivity layers correspond to stable Mesozoic and Palaeozoic land layers. Seismic velocity increases in the low-resistivity zone. Earthquake generally occurs at the boundary between resistivity structures. 68 refs., 9 figs., 2 tabs.

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.

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.

Incompressible Newtonian fluid simulation is experimentally applied to faults typical of the compression and extension fields. A fault-bend folding structure of the flat-ramp flat fault in the compression field and a folding structure of a normal fault in the extension field are studied, and the results are compared with those obtained by the balanced cross section method. The result of calculation indicates that the velocity gradient with the ramp angle set at 30deg is correspondent to stress and that stress concentration is taking place at the ramp section of the fault. This solution is an approximation and does not necessary support the conservation of area but, when the ramp angle is allowed to change from 10 through 40deg, it is found that the conservation of area holds though roughly. It is found that the configuration of the folding structure formed by a flat-ramp flat fault is positioned between the anomalous-mode layer parallel shear typical of a balanced cross section and the folding structure formed by a vertical shear. 7 refs., 7 figs.

The paper investigates relations between the damage caused by the Hyogo-ken Nanbu earthquake and the deep underground structures. A characteristic of the earthquake damage distribution is that the damage concentrated near faults. Most of the damages were seen on the side of faults` relatively falling rather than right above the faults and of their slightly slanting to the seaside. Distribution like this seems to be closely related to underground structures. Therefore, a distribution map of the depth of basement granite in Osaka sedimentary basin was drawn, referring to the data on basement rock depth obtained from the distribution map of gravity anomaly and the result of the survey using the air gun reflection method. Moreover, cubic underground structures were determined by 3-D gravity analysis. The result was concluded as follows: when observing the M7 zone of the low land, in particular, where the damage was great from an aspect of gravity anomaly, the basement rock below the zone declined near the cliff toward the sea, which indicates a great possibility of its being a fault. There is a high possibility that the zone suffered mostly from the damage caused by focusing by refraction and total reflection of seismic wave rays. 3 refs., 8 figs.

This paper reports discussions on subsurface structure of the Kobe area by means of microgravity survey. A Bouguer anomaly distribution graph was obtained (which is close to a near straight line) by measuring the gravity at measurement points with an interval of about 25 m along a traverse line (with a total length of about 1.7 km) in an approximately NNW-SSE direction crossing the downtown of the city of Kobe. Viewing the residuals to a straight line linking the values at both ends of the traverse line revealed that the gradient in the Bouguer anomaly distribution changes as if it is bent at a point near the center of the traverse line as a boundary. Deriving the residuals from fine changes seen in a distribution graph for the residuals made clear that this residual distribution has two discontinuous points. The paper indicates that the bending point in the former case corresponds to a reverse fault in a base bed of a flat land as compared with the result of model calculation on the base structure and gravity distribution. The discontinuous points in the latter case agree with positions of fault distribution derived by a reflection elastic wave survey. 6 refs., 4 figs.

An analysis was made on turbulent heat diffusion in a multi-compartment structure necessary for designing calorific power and environment for functional systems used in marine vessels and off-shore structures. In a multi-compartment structure, the diffusion phenomenon is complex because of movement of air flow in turbulence and buoyancy resulted from non-isothermal condition. The phenomenon is largely affected by space shapes and walls, and the conditions in heat diffusion field is governed also by shapes of opening connecting the compartments. An analysis was made by using the SIMPLE method on turbulent heat diffusion in a multi-compartment space with high Raleigh number in which natural convection is dominant. If the opening is small, the Coanda effect appears, in which air flow passing through the opening rises along the wall, wherein a high-temperature layer is formed near the ceiling, making the heat diffusion inactive. If the opening is large, a jetting flow from the opening and a large circulating flow are created, which cause active advection mixture, making temperature gradient smaller in the upper layer. Heat transfer intensity in an opening on a partition wall decays in proportion with 1/4th power of the opening ratio. 7 refs., 11 figs.

The Hokkaido Underground Resources Investigation Institute has prepared in 1995 a detailed temperature gradient chart that shows local anomalies around volcanoes. This paper describes an attempt to derive crustal temperature structure of Hokkaido from the above data. The model was hypothesized as a primary model in which no thermal convection exists. In volcanic and geothermal areas which show a temperature gradient of more than 100 {degree}C km {sup -1}, a solidus temperature is reached at a depth shallower than 10 km. Below the volcanic chain forming the Chishima arc, a partially melted region exists in a width of about 100 km. Most of the areas in the southern Hokkaido have the temperature reached the solidus temperature in the crust. On the other hand, in most of the areas of the forefront side, no solidus temperature is reached in the crust. In the temperature structure of a cross section crossing almost orthogonally with the volcanic front passing through Mt. Daisetsu, a high temperature area reaches to a shallow portion beneath Mt. Daisetsu, where the depth at which the solidus temperature is reached is 10 km or shallower. The range of area where the solidus depth is shallower than 10 km has a south-west width of about 40 km. This means that a partially melted area with a size of 40 km in the horizontal direction exists at a depth of several kilometers. 20 refs., 3 figs.

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.

A field survey was conducted of oil shipment depots in Java and Bali islands owned by Indonesia's state-run oil company to study measures for reduction in greenhouse effect gas emissions. Studies were made on the grasp of the amount of the hydrocarbon vapor emitted into the air, the amount of the gasoline recovered in case of adopting the vapor emission preventive technology, equipment cost/operational cost, etc. Concretely, the following three were studied: change of the gasoline storage tank to the inner floating roof type, and prevention of evaporation loss at the time of receiving and breathing loss caused by temperature changes; replacement with the vapor recovery type loading arm to recover gasoline vapor generated at the time of shipment/filling, and installation of the vapor recovery unit to recover vapor as gasoline; vapor balance system to recover in underground tank the gasoline vapor generated at the time of filling gasoline at gas station. As a result of the study, the recovered gasoline amount was 66,393 Kl/y and the CO2 reduction amount was 14,474 t/y at oil shipment depots and approximately 650 gasoline stations in Jakarta and Surabaya.

Storing and managing comprehensively a huge amount of data acquired in developing the coal liquefaction technologies would greatly contribute to moving forward the development of the coal liquefaction technologies, and realizing a commercial plant being the ultimate goal. It is intended to investigate the current status of information management systems used for development projects being implemented or planned in developing the coal liquefaction technologies. It is also intended to structure a coal liquefaction database system to utilize comprehensively and effective the information discovered by the above investigation. The current fiscal year has performed developments on the following items to structure a coal liquefaction database system by using a computer: (1) conceptual design of the fundamental database, and (2) basic design on a general technological information retrieval system. The development during the current fiscal year established a method to classify levels of data accommodation for the fundamental database based on the investigation and analysis of the experimental data. In addition, with regard to the general technological information retrieval system, summarization was performed on the specifications of the hardware and software, the basic configuration, the input and output specifications, and the retrieval screens.

With an objective to elucidate the relationship between the central tectonic line in the Kanto area and the active faults appearing in topography, seismic exploration using the reflection method has been carried out. The course of traverse was set in the south west to north east direction starting from the north east part of the Kanto mountainous area to the Menuma lowland passing through the Konan high plain. The line crosses nearly perpendicularly the direction in which the general beds in this area run. A 400-kg weight was used as a vibration source in the western half of the course of travel, and the MinivibT15000 (made by IVI Corporation) in the eastern half. Considerations given based on the preliminary CMP polymerization time cross section may be summarized as follows: the Fukaya fault cannot be tracked topographically further to the south east side than Mikejiri in Kumagaya City, but the reflection face from CMP 2050 to about 2100 shows an inclined bed on the south west side and a horizontal bed on the north east side; judging from change in the inclination in the beds, the Fukaya fault is thought to extend to the south east direction; the location of inclination change on the cross section turns to the south west side as the depth increases; and, if this is regarded as the fault face, the Fukaya fault could be said an inverse fault. 5 refs., 2 figs.

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

A discussion was given to elucidate the correlation between the crystallization of infrared ray permeating glass and the infrared ray permeability. The elucidation used infrared ray permeation spectrum, infrared ray absorption spectrum, and the Mosbauer effect. Reduction in permeability due to heat treatment of aluminate glass was discussed from the crystallization mechanism. Ultrafine crystals of mayenite phase having a composition ratio of CaO/Al2O3 = 1.7 diffuse and grow from the glass surface into interior as a result of heat treatment. The crystal growth is triggered by severance of Al-O tetrahedron. Gallate glass has CaGa2O4 and small amount of CaFe2O4 phase deposited when it is heat-treated in the vicinity of Tg. Although the infrared ray permeability decreases in association with the crystallization, the decrease is limited to crystallization on the glass surface, hence the permeability will not fall to zero. Laser irradiation on the gallate glass causes crystallization, resulting in reduced infrared ray permeability. Semi-stable Ca3Ga4O7 phase remains, however, because the heat energy amount is not large. Tellurite glass has {alpha}-TeO2 and a small amount of telluric acid iron deposit when heat-treated. 29 refs., 10 figs.

Feasibility of cabled-stayed bridges with 1000m-grade spans is discussed while re-examining the plan for constructing a Great Tatara Bridge to connect Honshu and Shikoku, Japan, and in this process various tasks and questions are isolated. Some which will be problems in designing the new bridge structure are taken up, including the load-bearing capability of the bridge as a whole, vibration of long cables, resistance to long-period earthquakes, and accuracy management during the construction work. Findings are stated below. A cable-stayed bridge is not significantly different from a suspension bridge and is sufficiently feasible until the span exceeds 1500m. When the span is longer, however, the bridge beam cross section needs be designed very prudently in view of the great axial force and wind load to be imposed on it. Effective for the assurance of load-bearing capability for a long-span cabled-stayed bridge is a structure in which load is elastically confined in the direction of the bridge axis. In connection with vibration damping for very long cables, it is verified that a new dimpled cable suits the purpose of suppressing wind load from increasing without reduction in damping effect. 28 refs., 23 figs., 7 tabs.

On the insert reinforcing bar structure for the connecting part of the main tower of cable stayed bridges, this paper reports verification results on a load resistant safety with a full-scale model, structure analysis and construction work. The basic structure was composed of a drilled steel shell, inserted reinforcing bars, fixing structure of bars in lining concrete of the shell and a pressure bearing plate. As an experimental result, the connecting part had a sufficient load carrying capacity against both tensile and compressive loads. The shear stress of the insert reinforcing bar structure was estimated successfully under von Mises`s condition. The shear spring constant in deformation characteristics was linearly proportional to an inserted reinforcing bar ratio. In earthquake, nearly 60% of an allowable compressive load was transferred to concrete through the pressure bearing plate. The analytical results of load resistant deformation characteristics of the connecting part well agreed with experimental ones, and the proposed analytical model was applicable to estimation of a dynamic behavior. 5 refs., 22 figs., 4 tabs.

For the purpose of technological cooperation on geothermal development, investigations and discussions have been given on the geological background in the geothermal areas in Central America where the Pacific volcanic zone stretches. The geology in Central America is divided largely into three geological structures distributed in a band form in the east-west direction. Among these structure, the Pacific Volcanic Province is a Caenozoic volcanic area ranging along the Pacific Ocean coast in the south-east direction, where young and active Quarternary volcanoes are lined straight over a distance of 1,400 km. The geological structure is such that continuously traceable rift valley or pit structure agrees with the array of volcanoes. The long and wide rift valley that governs this volcanic activity forms the base of the geothermal areas dotted in the above structure. Guatemala had been proceeding with a 24-MW power plant plan in Zunil, the most important point, but the construction has been delayed because of a landslide that caused impediment to the productive wells. The plant completion is now scheduled for 1995. El Salvador is the most advanced country in geothermal power generation, which operates three plants in the Ahuachapa geothermal area, with the output reaching 95 MW. The geothermal condition per production well is 110 tons per hour at 250{degree}C. Nicaragua had been successful in generating power of 70 KW with two plants in Momtombo by 1989. 22 refs., 8 figs., 4 tabs.

The Saitama prefectural government has been conducting basement structure exploration using the spatial autocorrelation method by dividing the entire plain area into meshes, for the purpose of improving the accuracy of estimating large-scale seismic damages. This paper reports the result of explorations on meshes in the east-west direction in the central part of Saitama Prefecture. The present exploration was intended on ten meshes in the east-west direction along the north latitude 36-degree line. The number of exploration points is 13 comprising three points on the hilly area bordering on the eastern edge of the Kanto mountainous area and ten points on the plain area. The arrangement constitutes a traverse line with a total distance of about 33 km from the west edge (Hatoyama-machi in Saitama Prefecture) to the east edge (Noda City in Chiba Prefecture). The phase velocities were estimated from the result of the array microtremor observations using the spatial autocorrelation method applied with the FET. The phase velocities were used to estimate underground structures by using an inverse analysis. As a result, detailed two-dimensional S-wave velocity structures were revealed on the traverse line. The velocity cross section expresses change in the basement structures with sufficient resolution, and at the same time the information is judged highly harmonious with existing deep boring data and the result of artificial earthquake exploration. 15 refs., 6 figs.

Methods were studied for determining the initial travel time and ray paths with stability when an non-linear travel time inversion is performed in an inhomogeneous structure. The travel time calculation was based on Faria and Stoffa`s method. First, the 2-dimension space was sectioned by grids, and `slowness` was assigned to all the lattice points. Starting from the vibration source, travel time at each lattice point is sequentially calculated. This method calculates travel time for any structure without breakup. In this study, an algorithm more sophisticated than the method of Faria, et al., was developed, and the improvement of travel time calculation accuracy led to the accurate determination of the direction of incidence into the lattice points during the initial motion. The calculation of ray paths was effected by tracing back from the receiving points the incidence into the lattice points or by following back the ray paths to the vibration source. This method performs stable calculation for a heavily inhomogeneous structure and, with the algorithm being simple, do the parallel programming as well. 1 ref., 6 figs., 1 tab.

This paper explains the results of research on full-length cDNA structure analysis for the period from April, 2000 to March, 2001. The outline of human genome sequence was published in June, 2000. In Japan, human gene analysis was such that, as the basic technology of the bio industry, a millennium project was decided in the budget of fiscal 2000. The full-length cDNA structure analysis is the core of the project. The libraries of cDNA were prepared using full-length and more than 4-5kbp-long cDNAs by oligo-capping method. It began from determining partial sequence data at end cDNA, and then, with new clones selected therefrom, full-length human cDNA sequence data were determined. The partial sequence data determined by fiscal 2000 were 1,035,000 clones while the full-length sequence data were 12,144 clones. The sequence data obtained were analyzed by homology search and translated into amino acid coding sequences, with predictions conducted on protein functions. A clustering method was examined that selects new clones from partial sequences. Database was constructed on gene expression profiles and disease-related gene sequence data. (NEDO)

Risk assessed structural positions in a pressurized fuselage of a transport-type aircraft applied with damage tolerance design are taken up as the subject of discussion. A small number of data obtained from inspections on the positions was used to discuss the Bayesian reliability analysis that can estimate also a proper non-periodic inspection schedule, while estimating proper values for uncertain factors. As a result, time period of generating fatigue cracks was determined according to procedure of detailed visual inspections. The analysis method was found capable of estimating values that are thought reasonable and the proper inspection schedule using these values, in spite of placing the fatigue crack progress expression in a very simple form and estimating both factors as the uncertain factors. Thus, the present analysis method was verified of its effectiveness. This study has discussed at the same time the structural positions, modeling of fatigue cracks generated and develop in the positions, conditions for destruction, damage factors, and capability of the inspection from different viewpoints. This reliability analysis method is thought effective also on such other structures as offshore structures. 18 refs., 8 figs., 1 tab.

This paper describes progress of the cooperation as to the integration of EC market and the change of industrial structure. For the structural change in the industry and economy accompanied by the integration of EC, effects of the Maastricht Treaty on the economic structure of EC are described. It is considered that the EC countries are affected by the political and economical restrictions due to the agreement of this treaty. For the change in the distribution structure accompanied by the integration of EC, obstruction factors of the deregulation of EC transportation market are especially investigated. Differences in the distribution capacity, various regulations and standards, and labor condition among individual countries are pointed out as the obstruction factors. For the unity of Germany and its economical and administrative influence, various problems are pointed out as to the economical confusion, progress in the de-nationalization of enterprises, management of real estate and land, etc. For the structural change in the road freight market in the member nations of EC, the structure of road freight market is made clear for the previous West Germany before the integration of European market. It is confirmed that the internationalization of the German domestic market is being promoted.

This paper considers problems in the change of the industrial structure as a result of the EC market integration, and the change of the physical distribution structure, mainly in cargo transportation. The market integration is being moved forward mainly on liberalization of flows in people, materials, and currencies, but the material flow liberalization has not progressed noticeably because of difficulty in deregulations. Changes in the transportation structure on the whole in the EC countries would not see a complete removal of barriers supported by the transportation licensing system because of issues in protecting domestic transportation markets and sharing the road expenses, even if the tariff barrier has been removed as a result of the market integration. Amid the predictions on deregulated legislations and intensified competition associated with the integration, the French trucking industry is indicated of its direction toward a two-layer structure comprising large-scale enterprises and medium-to-small companies. The German unification created problems in transferring from the socialistic command economy to the capitalistic market economy. The paper gives considerations on the real state of affairs in the privatization policy of the people-owned enterprises in the former East Germany, and its economic and managerial problems that should be solved amid the large-area EC market integration based on the mutualism over and above the economic system transition.

The X-ray diffraction analysis and the MO calculations of 1H-tetrazole were carried out, in order to explain its high stability. From the X-ray diffraction analysis, five bonds in the ring have intermediate lengths between single and double bond lengths. Therefore, 1H-tetrazole is quite stable because of its aromaticity. The N1-C5 distance of 1.315A is significantly short. The molecular structure which was calculated by the ab initio MO calculation of one 1H-tetrazole molecule at MP2/6-31G* level, showed a good agreement with our experimental one, except for the abnormal short N1-C5 distance. From the calculations of dimers and trimers, 1H-tetrazole is shown to be stabilized by a strong intermolecular electrostatic interaction between the protons and the delocalized electrons over the ring.

Aiming at production of ethanol, fat and oil and so on, ten kinds of miscellaneous cereal crops such as pearl-millet, soybean and so on were grown, and comparative investigation of the production rate which was considered utilization of whole plants were carried out. The suitability of vegetable wastes as methane fermentation materials for the methane gas production was investigated by the constituent analyses and methane fermentation experiments. Nine kinds of the grasses and vegetable wastes such as tomatoe buds, broccoli leaves were used for the investigation. As the results, the estimated yield of ethanol per 10 are from pearl-millet was 690 liter, the estimated yield of fat and oil per 10 are was 70 liter from soybean, The results of the analyses of nine kinds of the farm residues were as follows: (1) carbon content of about 40 %, (2) C/N ratio of 13 av., (3) C/P ratio of 91 av., and (4) the content of C,N and P was roughly appropriate. 680 to 760 milliliter of methane gas was produced from one gram of the dry matter of tomatoe bods, and in case of broccoli leaves, 424 milliliter of methane gas was produced, it was found that these values were not inferior to animal dung.

The metal dependence of mesoporous activated carbons with various metal acetylacetonate (acac) particles prepared from Morwell coal was studied. In experiment, the mixture of Morwell coal and acac metal complexes were dissipated into tetrahydrofuran, and after agitation in Ar atmosphere, the solvent was removed by vacuum distillation. Coal specimens with Fe(acac)3, Ni(acac)2 and Co(acac)2 as acac complexes were activated by exchanging flow gas with water vapor after heat treatment in N2 gas flow at 900{degree}C. The pore sizes of the specimens were obtained from N2 adsorption isotherms by BET method and BJH method. Conditions of pores and metals in the specimens were examined by XRD measurement and TEM observation. The relation between the above conditions and pore characteristics obtained from adsorption experiment was also examined. As a result, the difference in mesopore ratio between the specimens and blank specimens was larger in the order of Fe, Co and Ni, and the effect of added metal complexes was also larger in this order. 3 refs., 3 figs., 3 tabs.

This paper describes the following matters on application of an adaptively shifted integration technique to a buckling collapse analysis of framed structures: This method is a method in a finite element analysis using three-dimensional girder elements to arrange value integration points at optimal locations in a linear analysis if the elements are in an elastic transform condition on the whole. The method then moves the value integration points so that plastic hinge will occur in these locations immediately after part of the elements has yielded. The method was applied to analyzing an elastic buckling problem in several loading patterns for either a both-end supported or a one-end fixed beam member. A result was obtained that a number of elements required for one member is four at minimum. In a buckling analysis of framed structures, a satisfactory result was obtained by using an automatic element segmenting algorithm, which begins the analysis with one element one member, and immediately after a member is determined with a possibility of generation of buckling, splits that member only into four elements. 6 refs., 5 figs.

An efficient calculation method of potential distribution in the presence of an embedded body in multi-layer earth has been proposed by expanding the method of image with a consideration of multiple reflection between the ground surface and each underground boundary. For this method, when solving boundary integral equation with the potential of embedded body surface as only one unknown, i.e., when obtaining discretization equation, ordinary boundary element program developed for analyzing the finite closed region can be used. As an example, numerical calculation was conducted for the two-layer earth. The analysis expression of potential distribution in the case of the certain embedded body in two-layer earth has never published. Accordingly, the calculated results were compared with those by the integral equation method. As a result, it was concluded that the primary potential obtained from the present method agreed well with that obtained from the integral equation method. However, there was a disregarded difference in the secondary potential. For confirming the effectiveness, it was necessary to compare with another numerical calculation method, such as finite element method. 5 refs., 5 figs.

The computer aided coal structure construction system is proposed, and a computational construction example is presented. The coal structure construction engine of this system fabricates molecular structure by connecting fragments sequentially inputted through a user interface. The best structure candidate is determined using construction knowledge and partial energy evaluation every addition of one fragment, and this process is subsequently repeated. The structure evaluation engine analyzes the 3-D conformation candidate by molecular dynamics, and evaluates the conformation by determining the energy value of an optimum structure. As an example, this system was applied to construction of coal molecular structure based on the actual data of partial structure composed of 26 structures from 2l kinds of aromatic cluster structures, 27 bonds from 2 kinds of bridged bonds, and 16 groups from 2 kinds of terminal substitutional groups. As a result, this system could construct a superior structure according to expert knowledge from the viewpoint of energy. 6 refs., 5 figs., 2 tabs.

With the purpose of evaluating recoverable hot water quantity and elucidating the change over a long term, investigations were carried out, with the results summarized, on the geology, alteration zone, gravitational analysis, fluid geochemistry and hydraulics in the area. The investigations covered the area of 7 km x 6 km in about 30 km southwest of Sapporo City and were performed for the period from September 10, 1998 to October 31, 1999. The results were as follows. In the Jozankei area, with the Usubetu layer in the Old Tertiary system as the basement, layers are superposed from the Palaeogene Oligocene to the Quaternary Pleistocene. Distributing in various places between Yunosawa vicinity and Jozankei Hot Spring area are acid to neutral geothermal alteration zones. The hot spring gushing-out zone in the Jozankei hot spring area is supposed to be regulated by side-by-side cracks in the NE-SW direction. It was inferred from tritium concentration and a minor component ratio that, as the mechanism of forming a hot spring, water of precipitation origin circulating and residing for a long time on the Usubetsu layer which is marine sediment is heated by a volcanic heat source latent in the depth.

A learning system is proposed to explain the adaptive function of an eye movement consisting of compensatory and optokinetic reflex, and pursuit movements based on the brain anatomy and physiology. Thereby, the learning system is synthesized as an artificial neural network based on the structure and function of the biological neural network of flocculus. The role of neural paths into flocculus from stretch receptors of ocular muscles are discussed in detail from the viewpoint of system control engineering. The mathematical learning process is also shown taking into account the adaptive mechanism and the anatomical structure of vestibular nuclei. The experimental results through simulation confirm the validity of the hypothesis and the appropriateness of the inference process in connection with the proposed mathematical model. 18 refs., 11 figs.

A new energy vision was established in the Higashi Naruse Village in Akita Prefecture. The population of the village is continuing the decreasing trend since 1950 to 3,390 persons as of 2000. The annual energy demand in this village is about 320,000 GJ, accounted for by the consumer department at about 40%, the transportation department at about 36% and the industrial department at about 24%. The carbon dioxide emission amount therefrom is estimated 6,300 t-C annually. The expected usable quantity of new energies in the village would be available, in the decreasing order, in the wind power as the most promising source, forestry bio-mass, snow cold heat energy, agricultural bio-mass, and solar beam (heat). The total quantity would be 514,330 GJ annually in heat utilization, and 85,305 MWh in electric power. The new energy introducing project includes introduction of photovoltaic and wind power generation into Kurikoma Mountain Villa, introduction of wind power generation into the Junes skiing area and Oyanagi Natural Park, introduction of photovoltaic power generation and heat utilization into primary and middle schools, introduction of clean energy fueled automobiles into the village office, and introduction of photovoltaic power generation into general houses.

This survey was aimed at collecting the basic data for studying a possibility of conversion of the recovery system of refrigerant freons, mostly DFC, into HFC, etc., which has been proceeded with in Japan. Of HFCs, PFCs and SF{sub 6} used for survey, only SF{sub 6} is now being recovered and processed. As to HFCs, HFC-134a was arranged, and the recovery/destruction to meet users' handling methods are requested because of the diverse usage and users. The points of the control of emissions of chemical substances into the atmosphere are the decrease in number of times of transport/filling-up at the time of materials handling and the closed system in plants and installation. If considering the heightening of efficiency of materials flow, requested are the decrease in number of times of transport/filling-up, the increase in quantity received by users, and measures to be taken for leakage at the time of receiving. In relation to the conversion of the recovery system of refrigerant freons, mainly CFC, into HFC, etc., all the industries concerned with the generation of the used substances to the materials flow have to promote the technical development for the structure and recovery in cooperation with each other.

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.

Observations of microtremors were carried out to estimate the S-wave velocity structure by using arrays of seismographs around the Kyoto Research Park. The observation points were so arranged that equilateral triangle arrays may be formed with maximum radii at 0.2 km, 0.4 km and 0.8 km respectively with the premises of the Kyoto Research Park as the center. The seismographs have used seven vertical movement components (PELS), and were adjusted to a period of eight seconds. In addition, high-cut filters of 4 Hz were used because the observation areas are located in urban areas with heavy traffic. The analysis has used the spatial self-correlation method as a means to estimate phase velocity of surface waves contained in microtremors. As a result, phase velocity estimation has become possible for frequencies from about 0.4 Hz to 2 Hz, whereas the S-wave velocity structure was estimated to a depth of down to about 900 m by using as reference the result of the reflection method exploration having been carried out in the present areas. In addition, it was suggested that microtremors with frequencies higher than 1 Hz are in unsteady state in terms of time or space. 4 refs., 7 figs., 1 tab.

This paper reports application of a geothermal database system (GEOBASE) to analyzing subsurface structure in the Kakkonda geothermal area. Registered into the GEOBASE to analyze specific resistance structure in this area were depth information (well track and electric logging of existing wells), three-dimensional discretization data (two-dimensional analysis cross section using the MT method and distribution of micro-earthquake epicenters), and two-dimensional discretization data (altitude, and depth to top of the Kakkonda granite). The GEOBASE is capable of three-dimensional interpolation and three-dimensional indication respectively on the three-dimensional discretization data and the depth information table. The paper presents a depth compiling plan drawing for 2000 m below sea level and an SE-NE cross section compiling cross sectional drawing. The paper also indicates that the three-dimensional interpolation function of the GEOBASE renders comparison of spatial data capable of being done freely and quickly, thereby exhibiting power in the comprehensive analysis of this kind. 3 refs., 8 figs., 2 tabs.

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

In connection with hybrid structures in civil engineering construction, classification and application of composite types of steel and concrete are discussed. H steel embedded beam is a composite beam in which the H shape steel of the main beam is connected to rolled or welded H shape steel using cross beams. Composite structure columns are grouped into the composite column and the steel pipe concrete column. SRC piers are often adopted from the viewpoints of constraints for execution of works and vibration proof. Steel and concrete hybrid structure is a kind of structural system in which various kinds of materials such as steel, RC, or PC members are connected. The cable stayed bridge utilizes characteristics of steel and concrete effectively. For the piers of municipal expressway viaducts, there are executed cases of mixed structures which have RC, SRC columns for T shape piers and S structure for the bridges. SRC structure and composite columns are adopted often for structures of subway stations. 7 refs., 7 figs.

Reflection exploration of earthquakes was conducted in the continental shelf off the north-west Australia, and a report is made concerning the processing of the acquired data. A GI gun was used as the vibration source, and a wave quite similar to a pulse was generated. Hydrophones were arranged with group intervals of 12.5m, and high-resolution field data were acquired. An analog low cut filter was used to suppress the large-amplitude swell noise attributable to sea conditions. A digital filter was designed for the purpose of eliminating coherent noises from other survey ships. At the ultimate stage the f-k filter was applied to each of the shot records, and the effectiveness was verified. The traverse line was as long as 6700km and therefore the design window was set relatively long at 2.0-4.0s in the residual static correction phase. It was found that this setup is effective in improving the continuity of the reflection surface. 5 figs., 1 tab.

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.

The most important thing obtained from the survey is that study jointly by industrial circles and universities in the U.S. and Europe is much more advancing than that in Japan and is firmly established not only in industrial circles, universities and national research institutes, but in the whole society, actually producing a lot of favorable results. For Japan to catch up with the U.S. and Europe, needed is not only accumulation of the ideas in the past, but drastic measures to be taken from a new point of view. Concretely, it was proposed that by belonging intellectual properties such as patent rights to universities/research institutes and transferring their disposal rights to them, royalties of licenses are given back to inventors as incentives, and that as a body promoting the transfer to the industrial circle, `management organization` to which private vitality is introduced is established in universities/research institutes in order to promote interconnection between the industrial circle and universities. 15 refs., 35 figs., 36 tabs.

A regional new energy vision has been formulated for Kahoku town, Kumamoto Prefecture, for the realization of an energy resource circulation type regional community in which people earnestly strive to be symbiotic with nature. The results of related activities are shown in six chapters, which are (1) the prerequisites to the plan, (2) outline of the Kahoku town region, (3) surveys of the existing amount and expectedly available amount of new energy, (4) feasibility of new energy introduction, (5) assessment of new energy introduction plans and their effect, and (6) tasks to discharge, and policies to follow, for new energy introduction. In chapter (5), new energy introduction plans and introduction policies are shown. Plans are made for the incorporation of photovoltaic power facilities, small hydroelectric power facilities, and bamboo chip boilers into public facilities; the installation of 750 kW class wind power facilities; and the adoption of hybrid vehicles to serve as official special vehicles. It is expected that these plans when implemented will bring about a 1,400 t-c/year reduction in CO2 emissions. As for the introduction of wind power generation, the dimensions are determined by taking into consideration the prerequisites to a NEDO (New Energy and Industrial Technology Development Organization) grant.

A method for curing CFRP composite structures by using Joule effect is presented. Due to the presence of fiber to fiber contact, CFRP composites and their prepregs exhibit electrical conductivity in the direction transverse to fibers as well as in the fiber direction, and they can be considered as electrically homogeneous on a gross scale. Therefore, passing an electric current through a CFRP prepreg, it is self-heated due to the Joule effect. Feedback current control maintains the prepreg temperature at a desired level and makes the prepreg be cured by a specified cure cycle. Experimental verifiactions have been carried out to demonstrate the feasibility of the present technique. The applications to the bonding of CFRP components and to the patch repairs of effective CFRP structure are also described. 12 refs., 12 figs.

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.

The project for energy saving dissemination activities and technological assistance for Thailand is carried out, and the FY 2000 results are reported. For Siam Iron and Steel (SISCO), the experts are dispatched for reviewing the operating conditions of the facilities constructed by the model project, their maintenance and examination, time series diagnosis of the recuperator performance, and providing technical assistance for fuel consumption and high-load combustion of the downstream unit. Furthermore, the site survey and technical assistance are provided for two newly selected Thai steel enterprises, Sahaviriya Steel Industries Public Co. (SSI) and the Bangkok Iron and Steel Works Co. (BISW). For SSI, it is predicted that energy of approximately 50Mcal/ton can be saved by, e.g., enhancement of waste heat recovery, enhancement of heat insulation of skid pipes, introduction of steel discharging temperature prediction system, and combustion control. For BISW, it is predicted that energy of approximately 25Mcal/ton can be saved by, e.g., enhancement of waste heat recovery and reduction of heat loss in the waste gas. (NEDO)

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)

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

The engine structure attenuation has been experimentally analyzed by the newly developed in-cylinder excitation system. It can reproduce the complete cylinder pressure in non-running engine conditions by adopting the hydraulic and the piezoelectric actuator. The structure attenuation measured in this system has a good coincidence with the ones measured in actually engine operating conditions, meanwhile the current method, which applied only high frequency components as the excitation pressure, was shown to have the unsatisfied agreement. As a result, the proposed system has been concluded to be very useful to estimate the engine noise characteristics in non-running conditions. 4 refs., 11 figs., 1 tab.

The generation mechanism of the vertical vortices associated with the baroclinic instability and the effects of nonlinear term on the vortices are investigated by using both direct numerical simulation (DNS) and rapid distortion theory (RDT). Two kinds of the anisotropic flow fields are used as initial conditions. As a result, the initial anisotropy of Reynolds stresses is found to affect asymmetry of the vertical vortices. In the cases where the initial vertical velocity is set to be zero, the p. d. f. of the vertical vorticity tends to incline toward the anticyclonic side. When the vertical component of initial velocity is larger than the horizontal one, the cyclonic vortices are more enhanced. By comparing DNS and RDT, it is found that in both cases of the initial conditions the enhanced vortices of DNS are stretched in the vertical direction, which is not observed in the RDT results. This should be because the nonlinear vortex-stretching term intensifies and elongates vertical vortices in the vertical direction. The anticyclones are markedly augmented in low Prandtl number fluids, while the cyclones become dominant in the high Prandtl number case. In particular, the flow field becomes almost two-dimensionalized and Taylor columns are formed in the vertical direction in the low Prandtl number case. However, neither two-dimensionalization nor Taylor column is observed in the RDT analysis which neglects the nonlinear terms. (author)

Studies are made to define the working mechanism of semiconductor photocatalysts such as TiO2 and to establish designing guidelines for improving on their activity and functions. TiO2 in the air actively produces oxygen seeds for the oxidation and removal of NOx, etc. It is desired that a catalyst have a specific surface area large enough to retain the product of its action. To meet the need, a thin-film photocatalyst which is an aggregate of TiO2 crystals is produced by burning a film of a sol/gel system of reaction doped with macromolecules. This product has a larger specific surface area and is higher in pollutant-removing performance, and may be put into practical use. In another experiment, metal-carrying particles TiO2 suspended in water are employed for the reduction of CO2. Though the main product of catalysts carrying Pt or Pd is methane, a photocatalyst carrying RuO2 produces acetic acid mainly and loses less activity with the passage of time. A hybrid photocatalyst is composed of an organic pigment and inorganic semiconductor, synthesized through a covalent bond between a sililated-surface thin TiO2 film and porphyrin. It is confirmed that the newly developed process brings about an increase in electron migration efficiency. 3 figs.

This paper describes the creep analysis and torsional vibration analysis of cable-stayed bridges with two edge composite girders. The girder is composed of the concrete slab and the steel girder. I-girders are placed at both edges of the profile. Such a type of bridge was investigated. As the stress migrates by the creep of concrete slab, it is necessary to evaluate the influence of this creep precisely in designing. In the analysis, the composite girder was expressed not by the single member, but by the binary member consisting of concrete member and steel member. Two methods were employed, i.e., method A in which both members are connected by the rigid body beam and method B in which the profile of concrete is converted into the profile of steel. The method A provided better accuracy, but the method B was often sufficient. Torsional rigidity of the open profile structure was much smaller than that of the box profile. As the torsional natural frequency was low, proper torsional vibration analysis was indispensable especially from the viewpoint of wind resistance. Two methods were employed, which utilize the vibration analysis method for general space frame structures. Results of both methods were agreed mutually, but the second method provided better calculation efficiency. 10 refs., 9 figs., 6 tabs.

A hybrid or mixed structure (composite structures) are a matter of increasing concern which takes in each advantage of steel and concrete. A field of bridges is no exception, with the plan and construction carried out for the new type of composite bridge, such as a composite cable-stayed bridge and a composite extra dose bridge as a long span bridge, and a composite truss bridge and a corrugated steel plate web bridge as a medium-span bridge, with technological development becoming active in this field. In such a technological trend, a hybrid two-girder structure was devised, a structure consisting of a concrete filled steel pipe for a girder and a precast (PC) floor plate for a floor board, as the girder structure of a long-span cable-stayed bridge in the subject research; also, applicability was examined using, as an example, the composite cable-stayed bridge with hybrid girders employed for the span. This paper reports the result of the analysis of the entire system, the analysis made for the purpose of examining the characteristic and the feasibility of this hybrid girder. The analysis revealed the structural feasibility of the long-span composite cable-stayed bridge using two hybrid girders of concrete-filled steel pipes thus devised. (NEDO)

Studied in this project are concrete energy-saving procedures, and potentially saved energy and abated CO2 emissions in Town of Nishi Senboku, to promote energy saving and abatement of gas emissions which cause global warming. The energy-saving procedures studied include co-generation, utilization of waste heat, wind power generation, utilization of low-temperature heat by snow, fuel-efficient vehicles, use of insulators for houses, energy-saving type electric appliances, energy-saving activities, and eco-driving. The results indicate that the energy-saving activities and eco-driving can potentially more contribute to energy saving than the others. The study on introduction of energy-saving facilities in the 'Nukumori Hot Spring/Umeria' project indicates that the heat pump plus co-generation case is the most advantageous, because it can potentially reduce primary energy by 2,845,215MJ/y and CO2 emissions by 22,688kg-C/y. Introduction of energy-saving facilities is also studied for an information center in the Nishi-Senboku service area for the Akita Highway. The results indicate that the introduction can potentially reduce primary energy and CO2 emissions by 25 and 13%, respectively. (NEDO)

This investigation was intended to clarify the possibility of existence of geothermal reservoir layer by elucidating the underground structure and thermal source forming the geothermal system around Musadake, in the area extending over Nakashibetu-cho and Shibetu-cho, Shibetu district, Hokkaido, and further by grasping the distribution and properties of the geothermal alteration zone. The geothermal system of the subject area seems to be governed by Musadake - Mt. Shitabanupuri fault, its incidental bent zone, and the graben extending to the southeast side. The thermal source is presumably a magma reservoir that evolved Musa volcano. The depth hot water is presumed to exist in the underground depth around Mt. Imora; and it seems that the thermal conduction and volcanic ejecta are caused by a chain of volcano-related magma reservoirs around Musadake, the thermal source presumably. The depth hot water is estimated to be not less than 250 degrees C and a high Cl concentration. Within the graben, mudstones are distributed such as Kawakita layer and Yokoushigawa geological layer. Moreover, it is possible that an impermeable layer due to alteration is spread. (NEDO)

The purpose of this study is to develop the method and tools for changing the software structure flexibly along with the continuous continuous change of its environment and conditions of use. The goal is the software of very high adaptability by using soft-software components and flexible assembly. The CASE tool platform Sapid based on a fine-grained repository was developed and enforced for raising the abstraction level of program code and for mining potential flexible components. To reconstruct the software adaptable to a required environment, the SQM (Software Quark Model) was used in managing interconnectivity and other semantic relationships of among components. On these two basic systems, we developed various methods and tools such as those for static and dynamic analysis of very flexible software structures, program transformation description, program pattern extraction and composition component optimization by partial evaluation, component extraction by function slicing, code encapsulation, and component navigation and application.

This paper describes the results of the experiment in which crystallization of protein of reactive center purified from the photosynthetic film of thermophilic purple sulfur photosynthetic bacterium Chromatium tepidum whose hyrogen donor in photosynthesis is H2S instead of H2O was attempted. Crystallization was carried out by the vapor diffusion method and particularly by using ethylene glycol as precipitator at 4[degree]C after various investigations on the conditions of crystallization. By X-ray diffraction, this crystal was found to belong to the rhombic system, and it was estimated that the lattice constants, a, b, c equal to 140[angstrom], 190[angstrom] and 80[angstrom] respectively. This bacterium is a thermophilic bacterium having the optimum growth temperature of 48-50 [degree]C and utilizes CO2 or H2CO3 as corbon source, ammonium, urea etc. as nitrogen source and thiosulfate as sulfur source. Moreover, another purpose of this investigation was to determine the thermophilic location by elucidating its configuration (although, as a result, the analysis of configuration had no sufficient resolution). It was confirmed that the enzyme system of photosynthetic film and its cytoplasm obtained by ultrasonic spallation of this cell have CO2 fixing activity utilizing light energy. 23 refs., 14 figs., 3 tabs.

The response strength in which deflection waves propagating in the elastic body of a large floating structure with an order of km in length and width was investigated. Attention was paid to the waves propagating the place fully away from the boundary of a very large floating body so as to obtain the dispersion relation of waves and the relation between incident waves and deflection waves. Next, the frequency response was checked from the aspect of the displacement amplitude and strength for beams and plates. The dispersion relation of waves propagating the place fully away from the boundary of a very large floating body and the relation between the waves and infinite-point incident waves were represented by an expression. Similarly, the waves propagates more than the infinite-point incident waves in frequency, wavelength, and speed. A lower-limit value exists in the propagation speed. The displacement and stress amplitudes are represented by a relational expression. For plates, the displacement amplitude increases when the wave direction coincides with the small-rigidity direction. The stress amplitude is maximized when the waves corresponding to the ``wave below a floating body = size of a characteristic wave number`` reach the large-rigidity direction. 10 refs., 10 figs., 2 tabs.

Five cross sections were applied as a result of MT method investigations in addition to the results of conventional analyses at the Kakkonda geothermal area; three-dimensional resistivity distribution was made into a database by using the Kriging method which makes a matching with anisotropy of seismic center distribution in micro-earthquakes; and the database was compared with the data derived from surveys on the pilot survey well WD-1a and the side-truck well WD-1b thereof. As a result, it was found that the well WD 1b which encountered a water loss zone had the water loss zone exist in a region with relatively lower resistivity than in the well WD-1a which did not encounter a water loss zone. The region in which the water loss zone was encountered existed in a very steep slope region going from the high resistivity region in the west side toward the low resistivity region in the east side. This fact suggests a possibility that fractures have developed in this region with sharp slope in the resistivity in this area. Adding three-dimensional complementary function to the GEOBASE database by using a simple Kriging allowed the direction of anisotropy in spatial data to be freely and quickly decided. It was learned that this capability exhibits strong power in a mapping work in structures where such anisotropy as a geothermal zone is highly dominant. 5 refs., 8 figs., 2 tabs.

The carbon fiber reinforced carbon composite materials (C/C composites) strong at ultrahigh temperatures are taken up. So as to improve on its resistance to oxidation, corrosion, and abrasion as well as on its strength at ultrahigh temperatures, an ion engineering-assisted technique is used to reform the C/C composite surface layer and a technology is developed for thin coating formation on the C/C composite surface. Next, technologies are developed for multifunction coating formation on top of the surface, for defect prevention or removal from the C/C composite, and for adhesion enhancement between the C/C composite fibers and the matrix. Technologies are further developed for evaluating hostile environment withstanding capabilities at ultrahigh temperatures. In this fiscal year, in the study of microstructure controlling multilayer coating technologies, development is conducted of technologies of ion engineering-assisted surface control and reform and of technologies of forming multifunctional coatings high in reliability and resistance to corrosion. In the field of microstructure control composition, 3-dimensional carbon fiber reinforced carbon composite materials are manufactured by way of trial and evaluated, and their behavior under rigorous conditions is evaluated.

In this paper, bond cleavage reactions are discussed in relation to the softening and solubilization of coal. Were used 9,10-dihydroanthracene (DHA) and 9,10-dihydrophenanthrene (DHP) as models of hydrogen donating compounds in coal, and bibenzyl, 1,2-diethane, benzylphenylether, and 1,5-dibenzylnaphthalene were used as models of bridge structure compounds. They were compared mutually, as to reactivity of coal against DHA and DHP. For the homolytic cleavage of bridges, DHA with excellent radical supplement performance provided excellent hydrogen donating performance. While, for the ipso-position cleavage of bridges, it was found that DHP can act as an effective hydrogen donor. For the reaction between coal and hydrogenated aromatic compounds, cleavage of relatively weak bonds, such as ether linkage and dimethylene linkage, occurred at about 380{degree}C, and hydrogen from DHA or DHP was consumed. On the other hand, the results suggested that the cleavage reaction at ipso-position affected by hydrogen donating solvent is also important at temperature range around 420{degree}C. 2 refs., 3 figs., 1 tab.

Triaxial drill-bit VSP (vertical seismic profiling) method is applied to the Soultz HDR (hot dry rock) field, France, where an artificial reservoir is provided inside the bedrock, and the structure inside the rockbed is estimated. An elastic wave detector is installed in the rockbed in this field, and data are acquired having frequency components up to approximately 1kHz. The trajectory of particles due to excavation noise is analyzed, and it is found that the drill-bit is the primary source of noise during excavation and that the SV-wave dominates in the emitted noise. Estimating the subsurface structure aided by the principle of the triaxial drill-bit VSP method, the lower part is detected of the artificial reservoir formed by hydraulic fracturing. As is reported in this paper, when the principle of the subject VSP method is considered, it has to be said that it is quite difficult to employ this method to extensively estimate the subsurface structure on the basis of measurements of the inside of the rockbed. There is a plan for a future study of a technique for accurately and extensively estimating subsurface structures by use of a small number of sensors. 8 refs., 7 figs.

Environmental profiles of agricultural chemicals in a river flowing into Lake Teganuma were surveyed. Their dissolution and adsorption were investigated by using indoor experiments, and their behaviors were discussed from a viewpoint of molecular structure in the compounds. The herbicides detected in the river contained CNP and Benthiocarb were at high concentration at the time of spraying, but decreased sharply thereafter. The CNP had lower concentration than Benthiocarb in the river, indicating little amount flowing out from paddy fields. These differences in the environmental profiles should be attributable to natures of the herbicides. An indoor experiment has revealed that Benthiocarb has lower solubility and higher absorption strength than CNP. It was found with respect to the chemical structures that polarity increases if hetero atoms and hydrophilic substituents exist in moleculars; the solubility of Benthiocarb grows higher than that of hydrocarbons; and adsorption power relates to the area of contact with absorbing media, and absorption rate relates to the solubility, absorption power, and three-dimensional structure. 23 refs., 7 figs., 4 tabs.

This article introduces the electron beam curing (EBC), which is high speed non-heating cure technique for the high performance resin for structures, conducted by Aerospacial Co., Ltd. In this technique, very strong electron beam and X-ray are used in response to the thickness of curing region of members, and the muzzle has energy of 10 MeV as permeation control energy and power of 20 kW as cure time control power. Advantages of fabrication of composite products by EBC is derived from the elimination of exoergic and heating curing processes and the local cure molding. For the EBC, the residual stress is not generated, the size is stable, the insertion of different materials is easy without mismatch of thermal expansion between the composites and metals, the homogeneous bridge can be obtained to stabilize the material quality, the processing time can be shortened, it is suitable to mass production, and the cure of products can be controlled. About 30% to 40% of the cost of products can be reduced. 1 ref., 6 figs., 1 tab.

Based on the electrical logging data of the existed well and Schlumberger sounding data obtained in 1974, a two-dimensional inversion analysis of the specific resistance profile was conducted at the Akinomiya geothermal field, Akita Prefecture. From the electrical logging data, relationships between the geology and the specific resistance were illustrated. The specific resistance values of basement rocks showed more than 100 ohm-m, which were higher than those of the other seams. Intrusive rocks and tuffs in the basement rocks showed locally low values less than 100 ohm-m. Younger volcanic rocks showed low values around 10 ohm-m. As a result of the two-dimensional inversion analysis, the basement rocks could be detected as high specific resistance layers. Accordingly, it was considered that the basement rocks in this field can be detected as high specific resistance layers by analyzing the results of field survey sufficiently. Low specific resistance zones were observed in the shallow depth, which corresponded to the fumarolic gases. There were some layers with remarkably varied specific resistance values, which were considered to be related with alteration. 6 refs., 3 figs.

The deformation mechanisms of submerged shell-like lattice structures with membrane are in principle of a non-conservative nature since the follower type hydrostatic pressure. In the region of large deformations, especially in the case of geometrically deep shell-like lattice structures, the system could be much more accurately defined in a mono-clinically convected coordinate description than the conventional spatial description. Also, a complete analysis of a non-conservative system requires a criterion since the system can have multiple ranges of stability and instability involving buckling and snapping. This paper presents the development of the governing equations for the finite deformations of shell-like lattices defined in a mono-clincally convected coordinate description and applies the same to different cases of lattice deformations. The validity of the formulations is verified for finite deformation. The examples of some geometrically special shell-like lattice structures are presented as well to show the feasibility of the present formulation. 5 refs., 11 figs.

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 fact that most commercial herbicide formulations in cur­rent use contain the herbicide in an immedi­ately available form that is readily released into the environment exacerbates the risk of ground and surface water contamination by rapid herbicide transport losses. In this work, we prepared slow release formula­tions of three herbicides (diuron, terbuthy­lazine, and MCPA widely applied to olive groves by preadsorbing the herbicides on hexadecyltrimethylammonium-modified montmorillonite.

Methods: Data from the 2007 Argentina Global School-based Student Health Survey (GSHS, a nationally representative survey of middle school students, were examined using age-adjusted logistic regression models. Results: Of the 1,328 participating students aged 13 to 15 years old, 51.9% reported drinking alcohol in the previous month, with higher rates among males (p = 0.04 and older students (p < 0.01. Both male and female drinkers were nearly twice as likely as non-drinkers to report being physically attacked, being in a physical fight, and having thoughts about self-directed violence. Among drinkers, those who reported poor mental health, were victims of bullying, used tobacco or drugs, or skipped school without per- mission were approximately twice as likely as other drinkers to have engaged in violent activities. Conclusion: Public health interventions targeting violence among young adolescents should be developed in combination with alcohol education programs.

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.

The study was made in terms of a large-capacity waste-fueled power plant, estimation of the waste amount considering wide-area processing, size of facilities, comparison of four types of combustion furnace, steam condition/seawater cooling/power generating efficiency, etc. As a result, the following were proposed: As to the size of facilities, a capacity as large as possible is recommended in the light of the scale merit of costs of the waste-fueled power plant and final disposal site and the environmental preservation. Concerning the high efficient power generation, recommended are 450degC and 60-80 ata which are steam conditions for coping with high temperature corrosion. In respect to seawater cooling, the adoption is recommended making good use of locational conditions since the output energy increases by approximately 16%. Any furnace types including the fluidized bed furnace are equal. The amount of dioxin becomes below 0.1ng/Nm{sup 3} because of the control of furnace combustion temperature, residence time, catalytic desulfurization facilities, blowing of activated coal into the flue, etc. 172 figs., 78 tabs.

For the purpose of elucidating effects of output fluctuations at the time of quantity introduction of wind power generation, conducted were observation of wind characteristics in Hokkaido and analysis of the characteristics, estimation of fluctuations in wind power output, analysis of fluctuations in system frequency, etc. In the observation of wind characteristics, wind velocity/wind direction were measured at observation posts of 30 wind turbines installed at 16 sites in Hokkaido. Concerning the conversion into wind power output, 10 cases were selected such as the case of passage of low atmospheric pressure, etc., and the generator unit and wind firm were simulated in detail. 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)

In this study, preparation of porous adsorbent with developed micro-pores and meso pores and open pores on the external surface is tried. Namely, PFR-sawdust activated carbon is produced by carbonizing the PFR-sawdust composite materials obtained by adding KOH-immersed wood powders in the preparation of phenol-formaldehyde resin(PFR). Additionally, as a comparative test, KOH is added directly into PFR and PFR-KOH activated carbon is prepared by carbonization. Simultaneously with the clarification of the difference of pore structure between said two kinds of activated carbons, a various kinds of adsorbing tests are carried out to evaluate the adsorbing effects thereof. PFR-KOH activated carbon having a high specific surface area of 3500 m{sup 2}/g and a large number of micro-pore and meso pores is extremely effective in absorption of gas phase while the yield and particle strength are low. PFR-sawdust has a specific surface area of 1500 m{sup 2}/g which is the same level of activated carbons on the market, but the yield thereof is twice as that of PFR-KOH. 9 refs., 5 figs., 3 tabs.

The Beijing Shuidian Research Institute of Geophysical Surveying has performed ocean seismic exploration in the area where the Fujian Pingtan bridge was planned to be constructed. The elastic wave exploration device is of a multi-functional type. The device has functions of acquiring, processing and analyzing data in seismic exploration using the reflection method, and can visualize subsurface conditions at the same time as performing the exploration. The planned bridge building area spans over a sea area of about 3500 m long with water depths from several meters to 30 meters. The foundation bed consists of dacite lithologic tuff and granodiorite. The seal level varies from 4.0 m to 4.8 m between high and low tides. According to the result of other measurements, the elastic wave propagation velocities of the sea water were found from 1475 to 1485 m/s, and the elastic wave propagation velocities at the surface bed of the sea bottom were from 1550 to 1700 m/s. The exploration used a workboat which moves at a constant speed while maintaining the offset between a transmitting source and a receiving source constant, executing vibration transmitting, receiving and recording all on the sea. The result of the exploration revealed that neither obstacles such as sunken ships nor marks of occurrence of ocean bottom landslides were present. 1 ref., 5 figs.

The surface of the annealed steel and the exfoliated interface of the coating for the hot dip galvanized Si containing steel sheets was characterized by using SEM (Scanning Electron Microscope), AES (Auger Electron Spectroscopy) and TEM (Transmission Electron Microscopy). The adhesion of the coatings have depended on the Si content of the steel. It have been found that MnSiO{sub 3} particles are formed at the surface of the annealed steels having high Si content and that two types of grain having different distribution of the oxide exist in the steels. Large oxide particles have been formed in one type of grain and small particles are formed in the other type of grain. The different type of Fe-Zn alloy are formed on two types of grains. It have been observed that the oxide particles exist at the interface of exfoliated coatings after the adhesion test for the steels with high Si content. The distribution of the oxide particles observed at the bottom of the exfoliated coating is quite similar to that of the surface oxide of the annealed steel. From these results, the exfoliation of the coating has initiated at the oxide particles of the steel surface that has been not reduced during the hot dip galvanizing. (author)

Formulation was made on a one-dimensional beam finite element which is effective in analyzing structural response of very large floating structures by modeling them on beams on an elastic foundation. This element allows strict solution of vibration response in the beams on the elastic foundation to be calculated efficiently for a case where mass and rigidity change in the longitudinal direction. This analysis method was used to analyze structural response of a large pontoon-type floating structure to investigate mass in the end part for the structural response and the effect of decay while passing the structure. With a pontoon-type floating structure, reduction in bends and bending stress in the end part of the floating structure is important in designing the structure. Reducing the mass in the end part is effective as a means to avoid resonance in these responses and reduce the responses. Increase in rigidity of a floating structure shifts the peak in quasi-static response to lower frequency side, and reduces response in resonance, hence it is advantageous for improving the response. Since incident waves decay while passing through the floating structure, response in the lower wave side decreases. The peak frequency in the quasi-static response also decreases at the end part of the structure in the upper wave side due to decay in wave force. 7 refs., 11 figs., 1 tab.

Microtremor observations have been carried out with an objective to estimate underground structures including the foundation depth in the Osaka-Kobe area which has been greatly damaged by the Hyogoken-nanbu earthquake in 1995. Different organizations have made seismic surveys and boring investigations in this area, by which elucidation has been made on the underground structures. The present observations are intended to identify S-wave velocity distribution in a wide area from the ground surface to the foundation, which is difficult to be verified by using conventional surveys and investigations. Methods to detect surface waves which are contained in microtremors include the frequency-wave number method (the F-K method) and the spatial autocorrelation method (the SPAC method). The SPAC method can estimate phase velocities of longer waves for the size of an array than with the F-K method, and is more advantageous in estimating ground structures at greater depths. S-wave velocity structure was estimated down to the foundation rocks existing in depths of about 0.5 to 2.0 km. For estimating the phase velocities in Raleigh waves, the SPAC method and the expanded spatial autocorrelation method were used. The underground structures thus derived showed a good agreement with the results of explorations using other methods. 8 figs., 1 tab.

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)

Development of the semiconductor photocatalyst such as titanium dioxide is important for photo-energy conversion and purification of the environment. We make clear that the mechanism of the photocatalysis using a spectroscopic or physico-chemical methods, and we developed the new photocatalyst with the control of the surface area, porosity, infinitesimal content, and surface modification of the catalyst surface. Titanium dioxide thin film photocatalysts were prepared by the dip coating method. Surface structure of the thin film was formed by the aggregated TiO{sub 2} anatase particle, its size was around 5 nm. This thin films effectively oxidazed NO, its photocatalytic activity is higher than that of commercial photocatalyst. Metal oxide anchored TiO{sub 2} photocatalysts (RuO{sub 2}/TiO{sub 2}) were prepared by the co-precipitation method. Effective charge separation of the RuO{sub 2}/TiO{sub 2} were confirmed by the measurement of ESR. The RuO{sub 2}/TiO{sub 2} photocatalyst successfully reduced CO{sub 2} and preserved its activity for much longer period than metal loaded catalyst. Hybrid photofunctionalized material was prepared by anchoring porphyrin moieties on the titanium dioxide surface. The relative quantum yield of electron transfer from porphyrin to the titanium dioxide conduction band has been markedly increased by water treatment of quanternized porphyrin-titanium dioxide covalently linked systems owing to removal of adsorbed porphyrin domains.

The project of (research and development of methods for wide-area thermal structure exploitation) is to pursue (1) development of heat flow rate analyzers, and researches on the methods for measurement/analysis of heat flow rates, (2) researches on geological thermometers with the cores collected from test bores as the samples, (3) observation/analysis of microearthquakes, and application of the results to the geothermal structure exploitation, and (4) development, on a trial basis, small, light air drilling machines. The method for clearly elucidating thermal structures has not been well established. Therefore, a test bore was drilled to measure temperature and collect the core samples in the wide-area geothermal district at Kita Yahata-daira as the model district, for measurement of heat flows, and analysis of the cores to estimate temperature at which they are formed. Microearthquakes, which frequently occur in geothermal areas, are also observed for extended periods. This project of (research and development of methods for wide-area thermal structure exploitation) is aimed at, based on the above efforts, to estimate/elucidate depth of thermal sources by the geological, geophysical and geochemical studies, relationships between geological structures and high-temperature zones, geothermal propagation structures, and geothermal reserves.

Research and development has been made on technologies to reduce sulfur content in light oil and on optimization of light oil quality. This paper summarizes the achievements in fiscal 2000. 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.

In terms of coal conversion reaction, the behavior of bituminous coal heated beyond a glass transition point was examined on the basis of pyrolyzed products, and the effect of an increase in proton mobility on promotion of coal decomposition was evaluated. In experiment, after Illinois bituminous coal specimen was heated up to a specific temperature in N2 or He gas flow at a rate of 5K/min, the specimen was directly transferred to a pyrolyzer for instantaneous pyrolysis. As the experimental result, the glass transition temperature of the Illinois coal specimen was calculated to be 589K from a differential scanning calorimetry (DSC) profile. From the pyrolysis result of the Illinois coal specimen heated up to 623K, the char yield decreased by 3kg as compared with that of the original coal, while the tar yield increased by 4kg up to 27kg per 100kg of the original coal. This tar increase was larger than that of cooled coal. These results suggested that the donation of hydrogen radicals to coal fragments is improved with an increase in proton mobility. 4 refs., 4 figs., 1 tab.

For the improvement of quality of data collected by reflection aided seismic exploration using dynamite as the seismic source, information has to be collected about the surface layer structure before the charge depth is determined. For this purpose, refraction, electric, and electromagnetic exploration methods were tried. In the refraction method, an impactor was used as the seismic source. In the records, the surface wave prevails because vibration was generated on the surface. Analysis was made by the use of the initial travel time tomography. In the electric exploration, a double pole array was used to measure resistivity. The measured data was subjected to a fully automatic inversion for analysis. As the result, it was disclosed that it was useful to know the deep-level structure directly by use of tomographic methods in refraction seismic exploration so as to find the optimum charge level. Furthermore, about the electric and electromagnetic exploration techniques, it was found that these methods can be applied making use of resistivity to the evaluation of groundwater saturation. 7 refs., 5 figs., 3 tabs.

The velocity structure in the shallow ground structure was evaluated by observing microtremors of 1-10Hz in the Morioka City area. Plural wave sections free of vehicle noises or the like were selected out of the collected microtremor records, and the Fourier spectrum and coherence were calculated. Records sufficiently supporting the correlation between seismographs were chosen for the analysis. The phase velocity was calculated for each observation spot from plural array records by use of the F-K spectrum. The underground velocity structure was estimated by the inversion process using the matrix method. In this method, an early model was built on the basis of the observed phase velocity and the optimum underground velocity structure was determined by alternately performing two inversion processes: one for the case wherein the S-wave velocity is the sole parameter and the other for the case wherein the layer thickness is the sole parameter. As the result, a shallow underground velocity structure, which has good agreement with the available boring data in the Morioka City area, was successfully estimated, verifying the validity of this method. 4 refs., 7 figs.

This paper describes the calculation method of 3-D underground structures in TDME method which measures only field components. Recently, FDTD method was developed as calculation method in time domain difference calculus, and the forward analysis accuracy of 3-D fields was rapidly improved. The survey results using a large-scale loop (600m{times}360m) were numerically analyzed by FDTD method. 16 measuring lines were prepared in both X and Y directions, and measuring points were prepared on intersection points of the measuring lines. Since signal current is staircase one, step and impulse responses of the ground were determined by calculating magnetic field and its time differentiation. The rectangular body (120m{times}120m{times}100m) of 0.2S/m in conductivity (5 ohm m in resistivity) was installed 160m under the ground as 3-D resistivity anomaly. The ground of 0.01S/m (100 ohm m) was assumed. Time variation in horizontal magnetic field vector plot of impulse responses of the uniform ground could be observed. The position of the resistivity anomaly could be also determined from spacial differentiation of magnetic field of grid pattern measuring points. 1 ref., 6 figs.

Li2O-TeO2 glasses attract attention because of unique properties such as high density, high refractive index, large dielectric constants and high infrared transmittance. The short range structures of two samples of Li2O-TeO2 glasses (15:85 mol% Li2O-TeO2 and 25:75 mol% Li2O-TeO2) were investigated by X-ray diffraction technique. Interpretation of the obtained radial distribution functions was performed on the basis of the strength comparison method. The following conclusions were obtained: Two types of Te-O bond lengths of 0.18nm and 0.20nm are found in TeO4 tetragonal bipyramid. As network forming units, the TeO4 tetragonal bipyramids and TeO3 trigonal bipyramids are observed. The TeO4 tetragonal bipyramid units are transformed into the TeO3 trigonal bipyramids through the transient species of polyhedral with non-bridging oxygen atoms with increasing content of Li2O. The lone pair of Te atom does not contribute to the formation of the glass network. 17 refs., 6 figs., 2 tabs.

Alumina precursors have been prepared from AlCl3 by using n-alkylamines (C{sub n}H{sub 2n+1}NH2) as precipitant at pH 9.6 and pH 6.2, and the structure, composition, microstructure, and thermal decomposition behavior are investigated. The effects of the structure of the precursor on the decomposition behavior and on the surface area of porous alumina are also investigated. When alkylamines n{>=}6 are used, long periodicity phases are produced corresponding to larger than d=2.0nm spacing which can not be attributed to bayerite or pseudo-boehnite. Long periodicity phase is formed uniquely near the water content of about 50mass% (H2O/Al=4.5), and the spacing varies depending on the alkyl chainlength of amine. When the precipitate prepared at pH 6.2 is heated, water is desorbed at near 100degC, pseudo-baehnite phase is pyrolyzed at 300degC, and the precipitate changed into {gamma}-alumina at temperatures higher than 500degC. 16 refs., 9 figs.

The present semiconductor manufacturing process uses a great amount of PFC having large global warming coefficients and extremely long atmospheric life. A research was made particularly on reduction of its emission from etching processes. After introducing how the semiconductor industry has been working conventionally on protection of the global environment, this paper makes clear the purpose and positioning of this preceding research, as well as how it is moved forward. The paper also reports the results of analyzing and discussing the exhaust gases from etching devices using several kinds of substitute PFC gases. Survey results are reported on the possibilities of new substitute gases, plasma decomposition and treatment of exhaust gases, reaction process simulation, and in-situ analyzing and evaluating technologies. Investigations were made on the possibility of using no PFC in wiring processes which consume greater amount of PFC, as well as on wiring techniques using inter-layer insulation film with low dielectric rate, a new wiring structure forming technology, new functional elements, circuits and systems in a wide range. Proposals were given on specific research and development themes and plans that begin in fiscal 1999. (NEDO)

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)

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)

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)

The 40 'Surveys for promotion of joint implementation, etc.' conducted by NEDO (New Energy and Industrial Technology Development Organization) in fiscal 1998 aimed to pick out projects that would positively utilize the flexible measures (three Kyoto mechanisms) for the achievement of greenhouse gas reduction targets defined at COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). In this paper, concerning these 40 surveys, studies are conducted for reaching conclusions about setting baselines for the future, execution of similar feasibility studies in the future, application of flexible measures, and opinions towards project implementation. The 40 surveys were, concretely speaking, conducted not to work out policies for actualization of given projects but to consider philosophies of project actualization and baseline formation for the future. In this paper, project outlines, environmental impact assessment, and economic assessment (investment assessment) are put in order for each of the surveys, and relations between amounts of global warming gas reduced and project costs, and project profitability, are analyzed for each of the surveys.

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.

Attachment 4 of the FY 1998 report on development project of structural residence of the next generation describes the frame analysis system manual. NAPISOS is a program for analyzing static and dynamic responses of three-dimensional structures. The dynamic response is calculated by numerical integration in the time region. Dynamic load can handle dynamic exciting force, uniform seismic input and forced displacement at a node, and analyze linear elasticity and non-linear properties. The static load can handle nodal force, static seismic coefficient and forced displacement at a node, and analyze linear elasticity and non-linear properties. The static analysis also can perform analysis based on the time history response displacement method as the special case. The program implementation procedures fall into 4 general steps; first: inputting/processing of structural data, second: eigen value analysis or equivalent nodal force calculation, third: response calculation by direct integration, preparation of equivalent damping matrix or pre-stress analysis, and fourth: outputting the results. The input data related to control, structure and load are also described. (NEDO)

Described herein are the results of the FY1994 research program for structural defects of silicon-based amorphous materials for solar cells. The study on light generation defects of the a-Si:H system and rejuvenation process by annealing establishes the effects of light irradiation time on changed neutral dangling bond density as a result of light irradiation at varying temperature of 77K, room temperature and 393K. The study on annealing to rejuvenate light generation defects of various types of a-Si-H systems establishes the activation energy distribution with respect to annealing to remove light-induced defects, showing that hydrogen affects the distribution of light-induced defects. The study on decaying process of light-induced ESR for undoped and N-doped a-Si:H systems observes the decaying process of light-induced ESR, after light is cut off, extending for a period of several seconds to several hours at 77K for the a-Si-H systems containing N in a range from 0 to 12at%. The other results presented are space distribution of neutral defects of light-irradiated a-Si-H systems, and rejuvenation process of light-induced spin for the a-Si(1-x)N(x):H composition. 6 figs.

To promote the development of deep-seated geothermal resources in a rationalized way, studies were conducted about deep-seated geothermal resource assessment techniques, development guidelines, and the like. For the development of techniques for estimating deep-seated geothermal reservoir parameters, the Uenotai district, Akita Prefecture, and the Hatchobaru district, Oita Prefecture, were designated as model fields, and a geothermal system conceptual model was fabricated. Data of the two districts were registered in a database. Using these data, verification was performed of the validity of stochastic estimation techniques, large area flow simulation, rock/water equilibrium reaction simulation, and the like. As for the technique of deep-seated resource amount estimation, a simplified reservoir model was experimentally constructed based on parameters determined by the stochastic estimation of deep-seated reservoirs and on the conceptual model, and a method was studied for TOUGH2-based production prediction. Studies were also made about deep-seated geothermal resource development guidelines, such as exploration guidelines, exploration well boring guidelines, and geothermal fluid production guidelines.

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.

With the purpose of extending an exploring distance in electromagnetic tomography, a prototype was made as a device to receive and transmit continuous waves in a borehole, so that a tomographic observation was carried out on a jointed rock mass that had a conventionally short exploring distance. The device consisted of a transmitter, receiver, antenna, cable and surface controller, with a personal computer used for displaying and storing data. The prototype antenna was provided with a size insertable into a VP50 vinyl chloride tube. In order to determine a relative permittivity of a rock, a boring core was shaped and an impedance was measured. The measurement of tomography was carried out at 1m spaces apart in the bore holes with a distance of 50m in between. The received waveforms were stored in a floppy disk built in the personal computer. As a result of the analysis, a tomographic cross-section of the electromagnetic wave velocity was obtained, showing the distribution of sandstone with a high electromagnetic wave velocity and little joints, shale with a low electromagnetic wave velocity, chart with a high electromagnetic wave velocity, etc. 2 refs., 4 figs., 1 tab.

Tetrahydrofuran (THF) solubility and structure of the butylated products of meso-carbon microbeads (MCMB) were studied experimentally. In experiment, MCMB-A and MCMB-B obtained from two kinds of coal-tar pitch were used as specimens. MCMBs were butylated by BZ method using dibutylzinc-butyl iodide and KT method using K-butyl iodide-THF, and the butylated products were successfully obtained. The butylated products were investigated through THF solubility test, {sup 13}C-NMR measurement and gel permeation chromatography (GPC) measurement. As the experimental result, a BZ method produced the butylated products at a yield of nearly 170%, while a KT method produced them at a yield of nearly 130%. The THF solubility was estimated to be 89-97%. As the study result of molecular weight distributions by GPC measurement of solvent solubles, the molecular weight of raw material MCMB was estimated to be 590-770 in terms of polystyrene. 6 refs., 2 figs., 1 tab.

Studies were conducted about the method of estimating the underground S-wave velocity structure by inversion making use of the horizontal/vertical motion spectral ratio of microtremors. For this purpose, a dynamo-electric velocity type seismograph was used, capable of processing the east-west, north-south, and vertical components integratedly. For the purpose of sampling the Rayleigh wave spectral ratio, one out of all the azimuths was chosen, whose horizontal motion had a high Fourier frequency component coherency with the vertical motions. For the estimation of the underground S-wave velocity structure, parameters (P-wave velocity, S-wave velocity, density, and layer thickness) were determined from the minimum residual sum of squares involving the observed microtremor spectral ratio and the theoretical value calculated by use of a model structure. The known boring data was utilized for the study of the S-wave velocity in the top layer, and it was determined using an S-wave velocity estimation formula for the Morioka area constructed using the N-value, depth, and geological classification. It was found that the optimum S-wave velocity structure even below the top layer well reflects the S-wave velocity obtained by the estimation formula. 5 refs., 6 figs.

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)

Survey was made mainly on use of biotechnology as resource saving and energy saving processes. Biotechnology is in wide use in a pharmaceutical field, while its application is on the increase in agriculture, food, chemistry, energy and environment fields. The USA is ahead of Japan and Europe. In the USA, there are more than 1000 ventures, and R and D of biotechnology, in particular, gene analysis and manipulation techniques are in progress together with acquisition of patents. In biomass energy, production of ethanol from corn, and development of biodiesel are in progress in the USA and Europe, respectively. Use of biomass should be promoted because of its global environment compatibility and sustainable productivity. In the future bio-market, genome analysis and its application are most important, however, Japan is behind in such technology in the world. The Joint approach by industry, university and government is necessary from the viewpoint of a future marketability and international competitiveness. Promotion of a public acceptance and nurture of creative talents are also important. (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)

Wide-range MT (magnetotelluric) observation is conducted to collect knowledge of the middle and lower parts of the crust of the above-named region, about which but a little information is available, for comparison with information about Kurile islands arc tectonics. Three traverse lines crossing the Kurile islands roughly in the north-south direction and two lines running from east to west are used, with the observation stations totalling 48. The distance between observation stations is 7-8km on the Nijibetsu line, and approximately 15km on the Nakashibetsu and Akan lines. A very wide frequency range of 320-0.0005Hz is used for measuring, and these results in detection with success of resistivity structure details from shallow to deep layers in the crust. The collected data are analyzed, and it is estimated that the northern and central parts have a high-low-high three-layer structure while the southern part has a low-high two-layer structure. Since the data obtained at observation stations at the middle of the lines, in particular, have an extremely low apparent value of several ohm/m at about 1Kz in the absence of splits in the TM (transverse magnetic) and TE (transverse electric) modes, it is inferred that the low-resistivity layer is considerably thick and is distributed rather uniformly. 13 refs., 5 figs.

Since ion implantation causes material degradation by formation of crystalline defects, and hydrogen embrittlement deteriorates material strength, reduction of such defects has been positively studied. Study was made on a new active application of hydrogen separation into ion implantation defects. After H ion implantation of a proper depth into single-crystalline Si and SiC and successive annealing, single-crystalline films of sub-micron to several micron thick were obtained by hydrogen-induced delamination at the implantation depth due to hydrogen embrittlement in crystalline defects. The implantation depth is dependent on implantation energy. H atom forms (111) face defect through connection with dangling bond of crystalline defects. This crystal face defect forms a delamination plane through (100) face cleavage. This hydrogen embrittlement delamination by ion implantation is applicable to production of light-weight high-efficiency single-crystalline Si solar cells, and large single-crystalline SiC wafers as new resource saving process. 33 refs., 19 figs., 2 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.

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.

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)

UK is promoting to improve energy efficiency, along with liberalization of its energy markets. Germany concentrates its efforts in the 'Program for Energy Research and Energy Technologies.' France places emphasis on prevention of air pollution and rational use of energy. The R and D trends at public institutes, e.g., universities, for global environmental technologies are surveyed, from which a total of 14 themes are extracted as the seed technologies. At the same time, a total of 9 techniques potentially applicable to the seeds are extracted by mainly reviewing JICST and patent information, and assessed. The R&D trends of the IPCC-related researchers are also surveyed, but provide no theme directly applicable to the seeds. Most of the related themes at the private and public institutes surveyed, both domestic and abroad, are concentrated on carbon dioxide. (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)

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.

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)

Borehole N11-KN-1 was digged and investigated for clarifying the geothermal structure of the Kuwanosawa area, with attention fully paid to the existing survey results. The hole is inclined, 1,802.30m deep in total, with a casing pipe installed down to the 1,101.76m level. Temperature was measured and electrical logging was performed at levels 410m, 1,110m, and 1,802.23m while the hole walls were still exposed bear. The maximum temperature of 161 degrees C was observed at the hole bottom, and the product of permeability - layer thickness transmission coefficient was described by 3.72 to 4.75 times 10{sup -1} darcy.m. The geothermal structures in presence in the south-western part of the survey area and along the Wasabizawa fault were made clear, and it was found that there exists no high-temperature water system in the vicinity of borehole N11-NK-1. As tasks for the future, it was proposed that a geothermal survey of the south-eastern part which includes borehole N57-YO-2 and a geochemical survey of fluids including hot spring water and surface be conducted.

In relation to coal liquefaction reaction, the effect of the coexistence of transferable hydrogen (TH) from process solvent on reduction of radical concentration and the effect of pre-heat treatment on average structure of coals were studied. In experiment, change in radical concentration with temperature rise was measured using the system composed of Yallourn coal and process solvent. The results are as follows. Process solvent with a wide boiling point range of 180-420{degree}C is effective in suppressing an increase in radical concentration even at higher temperature. The effect of hydrogen-donating solvent increases with TH. It was also suggested that high-boiling point constituents in solvent stabilize radicals even over 400{degree}C by vapor phase hydrogenation. The experimental results of pre-heat treatment are as follows. Although the conversion improvement effect of TH is equivalent to that of the model solvent, TH tends to produce soluble products with smaller ring numbers. It was thus suggested that pre-heat treatment in process solvent is effective to inhibit retrogressive reactions. 6 refs., 5 figs., 1 tab.

This paper describes the distribution of Curie point depth and its characteristics determined from the spectral analysis of magnetic anomaly data in East and Southeast Asia. It also describes relationships between the Curie point depth and the other geophysical information such as topography, heat flow data and tectonics. The Curie point depths are shallower than about 10 km at volcanic and geothermal areas, between 15 and 25 km at island arcs and back arc rifts, deeper than 20 km at continents, and deeper than 30 km at trenches. The Curie point depth (Dc) estimated from the heat flow data can be expressed by Dc=k{theta}c/q where k is thermal conductivity, q is heat flow, and {theta}c is Curie point. Based on the Curie point depths obtained from Curie point depth analysis in the cross section of northeast Japan and the averaged values of heat flow at individual points, they are distributed along a line of k{theta}c=1500[Wm{sup -1}]. Values of k{theta}c are small near the axis of Japan trench and large in the northeast Japan. It is considered that local anomalies can not be grasped from the spectral analysis. 21 refs., 3 figs.

Cuttings from bores N11-TD-2 and N11-TD-3 drilled for the purpose of confirming the existence of geothermal resources in the Tsujinodake area were examined and tested, and the results of temperature logging, electrical logging, and water injection tests carried out during the structural boring work were analyzed. Activities were conducted in the four fields of (1) test boring work, (2) survey and measurement, (3) core cutting examination, and (4) comprehensive analysis. In bore N11-TD-2 positioned in the northern part of Tsujinodake, a sharp temperature rise was detected in the clay converted alteration zone between 200m above sea level and 200m below sea level. A high temperature of 215 degrees C was recorded at 200m below sea level, and it was found that high temperature geothermal water was in reserve at the bottom of the clay converted alteration zone between 100m above sea level and 200m below sea level. In bore N11-TD-3 in the southern wall of the Ata caldera, a convection type low temperature profile was observed at a shallow level and low temperature convection of underground water was detected there.

For geothermal development in the Musadake region, Shibetsu-gun, Hokkaido, structural boring was carried out and boreholes were inspected. In the structural boring survey, borehole N11-MD-3 was drilled as deep as 2,001.18 m, and borehole N11-MD-4 2001.44 m. Performed or tested for each of the two boreholes were temperature logging, electrical logging, temperature recovery, reinjection, core cutting examination, and so forth. The result of the temperature logging shows that temperature rise is slower at levels deeper than 1280 m in borehole N11-MD-3, with the maximum temperature marking 274 degrees C, and, in borehole N11-MD-4, the maximum temperature is 198 degrees C. No reinjection test is carried out because the ground pressure is too high to allow the replacement of the borehole content with fresh water. Analysis results lead to a conclusion that the hot fluid in this region originates in fossil seawater and in meteoric water, the latter arriving after a long-term permeation process, heated by thermal conduction to 270 degrees C or higher. It is inferred that the geothermal fluid flows in a fissure in the vicinity of the Musadake/Mt. Shitabanupuri fault and a fault orthogonally crossing the said fault for the formation of a high-temperature geothermal storage. (NEDO)

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)

For it, the following R and D are conducted in which nano crystal structure and non-equilibrium phase structure such as amorphous are controlled to the limits: 1) particle micro-dispersion technology; 2) high speed super plastic formation technology; 3) high density energy utilization control technology; 4) control cooling technology. In 1), study was made of alloy components and effects of the creation process which are needed for achievement of the nano level of crystal grain. In 2), conditions of vapor deposition and production in high speed particle deposition method are optimally selected, and amorphous and nano crystal structures can easily be produced. In 3), high corrosion-resistant amorphous alloy bulk materials with 5mm thickness and 10mm diameter were successfully trially manufactured. In 4), a bulk amorphous specimen with 10mm outer diameter, 6mm inner diameter and 1mm thickness which was fabricated in the forging method indicated favorable magnetic properties. A method to make a specimen which is more stable is being studied. (NEDO)

It was intended to elucidate characteristics of distribution of damages caused by an earthquake which occurs directly below an urban area. Therefore, numerical simulation using the pseudo-spectral method was performed on characteristics of seismic wave propagation in non-homogenous media composed of rock beds and sediment beds, and of seismic wave amplitudes on ground surface. The simulation has utilized information on underground structures disclosed by using the latest physical exploration method. The underground structure model assumed a two-dimensional model hypothesizing presence of upper, middle and lower beds in the Osaka bed group on granite, using as reference the information on S-wave velocity underground structure revealed by the microtremor exploration method. With an objective to elucidate characteristics of distribution of collapse ratio in the area from 8-chome, Okamoto, Higashinada Ward, Kobe City to 2-chome of Sakanasaki Minamicho, as damages suffered from the Hyogo-ken Nanbu Earthquake, a simulation has been performed varying the structure model based on the results derived by the microtremor exploration method and the reflection method. As a result, it was shown that the characteristics of the maximum amplitude distribution of displacement of ground surface, velocity and acceleration agree well with those of the collapse ratio distribution, and that the simulation using the pseudo-spectral method is an effective means to analyze the ground surface collapse ratio distribution. 5 refs., 3 figs.

A very large floating structure was replaced with the beam on an elastic foundation to examine the response characteristics in waves. Another evidence was regularly and numerically given for the basic characteristics of a very large floating body Suzuki found. New information was also obtained. The frequency response is mainly classified into a wave number control area and proper frequency control area when buoyancy elasticity exists. When the buoyancy structure is long and flexible, the proper frequency becomes continuous and the frequency control area becomes a resonance area. In the wave number control area, the Suzuki`s characteristic wave number becomes a control parameter, and various characteristic values are indicated by characteristic wave numbers. The response in the wave number control area becomes quasi-static when the distribution mass of buoyancy is fully small. The design in which the distribution mass of buoyancy is fully large must be avoided. In the displacement amplitude, the mass on the free end is severest. The proper frequency of vertical vibration relatively moves to the high-frequency side when buoyancy is considered as an elastic foundation. Attention must be thus paid to the proper frequency of vibration on the horizontal surface. 9 refs., 12 figs., 3 tabs.

It occasionally happens that there exists a part where reflection near the thrust is not clearly observed in a thrust zone seismic survey cross section. For the effective interpretation of such an occurrence, the use of geological structures as well as the reflected pattern is effective. When the velocity structures for a fold structure having a listric fault caused anticline (unidirectionally inclined with a backlimb, without a forelimb) and for a fault propagation fold are involved, a wrong interpretation may be made since they look alike in reflection wave pattern despite their difference in geological structure. In the concept of balanced cross section, a check is performed, when the stratum after deformation is recovered to the time of deposition, as to whether the geologic stratum area is conserved without excess or shortage. An excess or shortage occurs if there is an error in the model, and this shows that the fault surface or fold structure is not correctly reflected. Positive application of geological knowledge is required in the processing and interpreting of data from a seismic survey. 6 refs., 6 figs.

Pre-stacking depth migration treatment is studied for the estimation of the fold configuration from seismic survey cross sections. The estimation of a velocity structure is necessary for the execution of such treatment, and the utilization of structural-geological knowledge is required for its interpretation. The concept of balanced cross section in relation to the fault-bend fold constructs a stratum structure model under conditions that the deformation during fold and fault formation is a planar strain, that there is no change in volume due to deformation, and that a fold is a parallel fold. In addition to the above geometric and kinetic approach, there is another fold formation process simulation model using a Newtonian fluid for study from the viewpoint of dynamics. This simulation stands on the presumption that the boundary contains a ramp that had been in presence before fold formation and that an incompressible viscous matter is mounted on the top surface. The viscous matter flows and deforms for the formation of an anticline on the ramp. Such enables the reproduction of a fault-bend fold formation process, and helpful discussion may be furthered on the dynamic aspect of this simulation. 5 refs., 4 figs.

Japan National Oil Corporation Technology Research Center has carried out experiments on the three-dimensional seismic survey method which is regarded as an effective means for petroleum exploration. The experiments were conducted at the Minami Noshiro area in Akita Prefecture. Seismometer arrays were developed in radii of 30 to 300 m at seven points in the three-dimensional seismic exploration region to observe microtremors. The purpose is to estimate S-wave velocities from the ground surface to the foundation by using surface waves included in microtremors. Estimation of the surface bed structure is also included in the purpose since this is indispensable in seismic exploration using the reflection method. This paper reports results of the microtremor observations and the estimation on S-wave velocities (microtremor exploration). One or two kinds of arrays with different sizes composed of seven observation points per area were developed to observe microtremors independently. The important point in the result obtained in the present experiments is that a low velocity bed suggesting existence of faults was estimated. It will be necessary to repeat experiments and observations in the future to verify whether this microtremor exploration method has that much of exploration capability. For the time being, however, interest is addressed to considerations on comparison with the result of 3D experiments using the reflection method. 4 refs., 7 figs.

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)

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. A simulation on return on investment in GBT business suggests the effect of promoting PFI. (NEDO)

El tipo de diseño de la investigación es no experimental retrospectiva porque no se manipulan las variables y se buscan datos del pasado. Fue evaluada una población de N=40 conformada por 28 nadadores, 8 entrenadores y 4 dirigentes de distintas épocas, con una encuesta para recolectar datos de los orígenes y evolución de la natación de competencia en Mendoza. Asimismo se evaluó la evolución de los records de las pruebas de 100 metros en los cuatro estilos, los 400, 800 y 1500 metros libres ambos sexos en pileta de 25 y 50 metros. Se consideró la cantidad de clubes participantes, los nadadores con licencia nacional en los distintos años y las nominaciones para Seleccionados Nacionales en las distintas décadas. No se obtuvo diferencias estadísticamente significativas entre la evolución de los records realizados en pileta de 25 con la de 50 metros. Se comprobó que disminuyó tanto la cantidad de clubes participantes en los torneos desde 1950 hasta el año 2000 como la de nadadores federados. El estudio nos revela que el nivel competitivo de los nadadores se ha elevado por el aumento en las nominaciones a Seleccionados Nacionales. Como conclusión obtuvimos que posiblemente estos valores obtenidos se deban a la evolución en las técnicas de nado y en los métodos de entrenamiento, interrogante que puede servir para próximos estudios y que, en este caso, la cantidad de deportistas no es directamente proporcional a los logros deportivos.------------------------------------------------------------------------------The investigation that we carried out sustains in an exploratory and descriptive study.

This paper reports on experiments for acoustic excitation of plane shear structured flame. Flows of air separated into the higher velocity side and the lower velocity side by a partition on the center of a flow path merge at the measuring point to form a mixed layer with coherent structure. Fuel is supplied to this mixed layer with the flows so adjusted that the generated flame will attach to the partition on the lower velocity side. Acoustic excitation (at a sound pressure level of 100 dB to 120 dB) is performed in a speaker fitted on a wall on the higher velocity side. The paper mentions the results of the experiments as follows: the acoustic excitation produces such changes to diffusion flame in the plane shear layer as shorter flame and blue flame combustion and clarification of flame structures; as seen from spectral characteristics of temperature change in the flames, a flame acoustically excited strongly presents remarkable improvements in periodicity of the structure; as seen from sound pressure distribution in the flow direction at the measuring point, the flame zone of the flame acoustically excited strongly is positioned at the middle of the node and loop of a standing wave. 6 refs., 9 figs., 1 tab.

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 the evaluation and study of reservoirs and the amount of resources, a reservoir simulation is conducted to grasp the characteristics of reservoirs and the amount of resources. For this purpose, the origin and history of the Kakkonda geothermal field are studied, with special attention paid to the origin of the difference in temperature between the shallow-seated and deep-seated reservoirs, the geometry of granite at Kakkonda, the region of recharge of meteoric water, the distribution of saline concentration in the natural state and the cause of the occurrence, the amount of supply of fluids and heat from the depth to the reservoirs, etc. In the evaluation and study of the economic effectiveness of the exploitation of deep-seated geothermal resources, it is learned that, if a 50MW geothermal power station is to be built at a deep level (drilled depth of 3000m on the average) with a rate of 50% attained in drilling, the steam amount required at such a deep level (presumed to be 75t/h) will be more than twice that required at a shallow level (presumed to be 35/h).

In fiscal 1997, a fumarolic gas test is conducted at the deep-seated geothermal well WD-1b which was drilled in the preceding fiscal year. In the test, chemical and isotopic characteristics are compared between the fluids of the WD-1b and the other existing deep-seated wells, and it is found that the fluids from the WD1b originates in surface water just like the fluids from the others and that the constitution of its gas is not greatly affected by magmatic fluids. A PTS (Pressure, Temperature, Spinner flowmeter) logging is performed to observe conditions in the well with the fluids being discharged and to know the inflow point and rate the fumarolic fluids, and the result is utilized to presume the 3-dimensional stress in the vicinity of the WD-1. An isotopic measurement of water included in the fluids is conducted to examine the origin of the geothermal fluids, constant observation and analysis of micro-earthquakes are carried out, and the fluid flow and fluid hydraulic characteristics are also studied.

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.

For the contribution to elucidation of the geothermal structure in the Haneyama area, Oita Prefecture, the paper carried out the drilling of structural boring exploration wells, N6-HN-1 (1,605m) and N6-HN-2 (1,402m), and the well exploration. In the well exploration, the following were conducted: measurement of earth temperature, temperature recovery test, electrical log, simple water injection test, core/cutting observation, core test, powder X-ray diffraction analysis, physical property test, measurement of homogenization temperature of fluid inclusion, etc. In the temperature log and temperature recovery test, the terminal temperature at a 1,600m depth of N6-HN-1 well and at a 1,400m depth of N6-HN-2 well was 139.6 degrees C and 26.2 degrees C, respectively. The homogenization temperature of fluid inclusion was relatively higher, +70 degrees C to +100 degrees C, than that in the results of the temperature log, but was on the side of lower temperature, -30 degrees C to -100 degrees C, in a comparison with the saturated boiling curve of the earth surface and ground water level. Namely, it was thought that around the N6-HN-1 well, there used to exist the high temperature fluid of 250 degrees C or higher at the peak period of geothermal activities, but there only existed the geothermal water of approximately 140 degrees C at the present time.

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)

In addition, data were acquired relating to conditions such as steel composition affecting the formation of orientation in structures, work load and rolling temperature for areas to be recrystallized, holding temperature and time in the magnetic field, and intensity of the magnetic field. In the research for estimating mechanical properties of microstructures by computational science, a Monte Carlo simulation was carried out by employing the result of a polycrystal plasticity method program as the initial value, with a prototype established of the integrated simulation method from the deformation to the microstructure formation.

A new reciprocating engine was developed as an application of new mechanism named as `Z mechanism.` In this new engine, the piston motion is described by a simple sine function and gives lower velocity around top dead center than that in conventional piston engines. Thus, the mode of combustion in this engine is closer to constant-volume process and gives higher thermal efficiency than ordinary engines. Use of Z-mechanism also eliminated high-order components of vibration that ordinary engines suffer. Development high-performance engine was successfully conducted with this new mechanism. 4 refs., 11 figs., 1 tab.

This paper describes the state of progress in the cooperation in solar energy technologies among Japan, Australia and other country, the memorandum concluded for the new project, and the activity report on the NEDO/MUERI project. The progress in the cooperation in solar energy technologies among Japan, Australia and other country is divided into that of the new project and that of the continued project. The former relates to the start of the long-term endurance test project for photovoltaic solar modules in Oman. The location of the endurance test is the Sultan Qaboos University in the suburb of Muscat. Modules subjected to the endurance test consist of ten modules of five types. The test will be performed on air temperature, humidity, wind directions, insolation on horizontal surface, insolation on slanted surface, ultraviolet ray intensity, module temperatures, and electric characteristics of the modules. The continued project is an outdoor endurance test for the photovoltaic solar modules begun in fiscal 1996, which is executed by the Murdock University Energy Research Institute (MUERI). The endurance test locations were selected at Darwin, Alice Springs and Perth. This paper reports the photovoltaic solar module endurance test and investigation, as well as the periodical consultations as the activity report of the NEDO/MUERI project. (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)

Costa Rica takes a power generation system using hydro power generation as the main source, and possesses medium-capacity gas turbines to supplement needs in the dry season and the peak load. However, a problem has come up that, in addition to the cost rise in gas turbine fuel, the power generation efficiency has been aggravating due to aged deterioration of the generators being used. In association therewith, the problem is now a factor to increase CO2 emission, which is a worldwide problem. Keeping in mind to link it to the clean development mechanism (CDM), the present project is, taking up the SAN ANTONIO power plant as the investigation object, intended to perform a comprehensive discussion on the CO2 emission reducing effect, profitability, and proliferation effect, by executing the conceptual plant design. The up-grading plan for thermal power generation systems in Costa Rica consists of replacement of the gas turbines, handling of phase modifiers, and achievement of the combined cycle. The plan agrees with the present feasibility study intended of CO2 emission reduction, consisting of the modification plan of the SAN ANTONIO power plant, that is the plan to replace the over-aged gas turbines at the power plant. Its necessity has been identified. It was disclosed that the project has the effects of reducing CO2 of 82,000 tons annually, and the investment can be recovered in nine years. (NEDO)

With an objective of developing wind power generation systems that suit small to medium size islands in Japan, conceptual design was made on a 100-kW class wind mill to satisfy such requirements as no need of large heavy machines, and gust resisting performance. Investigations were performed on sites suitable for demonstration tests thereof. This paper reports the achievements in fiscal 1999. In investigating the site location feasibilities, which took small to medium size islands in Okinawa Prefecture as the discussion objects, environmental investigation, wind condition forecast and investigation, and system linkage investigation were carried out, whereas one point each in three islands were extracted as the promising sites. The system discussion and design called for wind velocity resistance of 80 m/s, system linkage percentage of 40% at maximum, power generation cost of 20 yen per kWh, design life of 20 years, constructability of requiring no large heavy machines, and operation mode of diesel hybrid use. Along with these specifications, conceptual design was performed on the system constituting elements, such as wind mill blades, generators, electric power control devices, and towers. In the blade aerodynamic test, wind tunnel tests were executed by using three types of blade wings. Sample blades were fabricated for the preparation of blade material tests. (NEDO)

With an objective of saving energy and reducing greenhouse gas emission, a modernization project has been discussed on the North Bangkok heavy oil burning thermal power plant owned by Electricity Generating Authority of Thailand (EGAT). The present project plans to withdraw the existing units No. 1, 2 and 3, and install two new generating facilities with the rated output of 358.3 MW using natural gas as fuel. The present feasibility survey has performed detailed comparative discussions on four cases, whereas a proposal was selected to withdraw all of the boilers, steam turbines, and generators, and install two single axis combined cycle systems whose output has been increased by using the existing fuel tank area. The energy saving effect by this project can reduce fuel consumption annually by 514 kt of crude oil equivalent. The greenhouse gas can be reduced annually by 2,680 kt-CO2. The project will require a total fund of about 57 billion yen. The profitability assessment calls for the internal profitability of 8.413% and the investment fund efficiency of 1.69%. The economic investment payback effect of this project is determined sufficient. (NEDO)

In Japan and Asian countries, the optimized treatment of industrial waste is the problem with the economic growth. Border-crossing movement of the waste for promotion of the renewable use is also a problem. Therefore, the International Symposium `98 on the industrial waste problem in the Asian region was held. China, Thailand, the Philippines and Korea were invited to Japan to give lectures. MITI of Japan reported on the present situation of Japan and the cooperation with Asian countries. The industrial circle reported on efforts for environmental protection measures to be taken, the industrial waste problem at companies which advanced into Asian countries, effects of the Basel Convention on recycling activities, Japan`s role in Asia, etc. In the panel discussion, promotion of cooperation for recycling technology and Japan`s support for formulating strategy on the industrial waste were requested to Japan, and the construction of an Asian area network was proposed. Concerning the cooperative system between governments and private companies, it was concluded that it was necessary to discuss it considering the actual state of each country. Importance of recycle and information exchange was realized again. 10 refs., 15 figs., 27 tabs.

A geology/alteration zone investigation and gravitational probing were carried out, with the results summarized, for the purpose of elucidating the structure of geothermal reservoir structure in the Kuwanosawa area. The investigation was implemented in the southeast part of Akita prefecture including Yuzawa city and Ogachimachi during the period between June 9 and August 31, 1999. The results were as follows. The geology of the investigation area consists of granite, as the base rock, and the covering Doroyu layer, Minasegawa layer, Sanzugawa layer and intrusive rocks in the Neo Tertiary system as well as Kabutosan layer and volcanic rocks in the Quaternary system. No wide area alteration zone existed, while vein-like alterations and hydrothermal veins along cracks were recognized, with the fluid inclusion homogenizing temperature showing 240-260 degrees C, which presumably indicates the existence of local hydrothermal activity until comparatively recently. The geothermal structure of the subject area is very likely dependent on thermal conduction from a deep thermal source existing in the Wasabizawa district. In the underground depth, it is inferred that a hydrothermal system is formed in the NW fault structure, lower part of cracks accompanying NS hydrothermal vein, and in the NNW/NE structures inferable from the gravitational probing.

This project was aimed at developing methods for producing basic chemicals from carbon monoxide and other stocks (the so-called C1 chemistry), in order to establish the techniques that could promote stable supply of basic chemicals from the new carbon resources in place of oil. It was a 7-year national project beginning in FY 1980, jointly implemented by the government, academic and industrial circles. Described herein are the overall evaluation of the results. There are several carbon resources other than oil, e.g., coal, natural gas, oil shale and tar sand. They are abundantly occurring, although unevenly, and various countries are developing these resources. They can be advantageously utilized as stocks for chemicals, after being converted into synthesis gases. In Japan, they have been efficiently developed cooperatively by national institutes, enterprises, academic circles and chemical industry, to produce the world's results, e.g., gas separation/purification techniques and new catalysts for new synthesis methods. This project was terminated because of the relaxed oil supply/demand situations and lowered crude prices in the middle of the 80's, which made stock conversion less urgent. (NEDO)

An International Symposium on the Asian Industrial Waste Issue was held in Tokyo on 4 February 1999, where lectures were delivered by participants representing China, the Philippines, Thailand, Malaysia, and Japan. More 150 people attended the event, with questions and answered animatedly exchanged between the lecturers and the audience. The progress of urbanization is quite rapid in China, with the quantity of waste increasing every years to justify the anticipation that there will be a very sharp increase in refuse incineration in the near future. Raising a serious problem in China these days is the plastic waste. In the Philippines, there are no private-sector waste treatment/disposal facilities and corporations are not obliged to take care of their waste. Consequently, very little treatment or recycling is being undertaken. In Thailand, although waste treatment/disposal centers are in operation financed by the Government and private sectors, the cost is very high, and the Government policy is that private investment will be encouraged and supported in future. In Malaysia, privatization is in progress of the business of managing waste in the solidified form. A comprehensive waste treatment/disposal plant was completed in 1998 by the endeavors of a Denmark-Malaysia consortium, and is in operation since then. (NEDO)

Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

To reduce the environmental pollution caused by lead eluted from the electronic equipment waste, the R and D on lead-free solder were conducted and the results were summarized. As to the basic characteristics, the evaluation test method was studied in terms of the range of melting temperature, mechanical strength, wettability and joint strength, to select a uniform test method. As the lead-free solder, Sn-Ag alloys were mainly used and mixed in a combination of Cu, Bi and In. Changes in characteristics were made clear by adding trace elements such as Ge, Mn and P. Relating to the applied characteristics, in selection of solder materials, materials were selected for which evaluation of the commercialization is proceeded with from a viewpoint of promotion of commercialization. Concerning the experimental evaluation of characteristics of lead-free solder in mounted substrates, it was indicated that basically lead-free solder can be practically used. Further, it was indicated that the Sn-Ag-Cu-Bi system depends not on solder composition but on active force, printing accuracy and flux characteristic of solder paste, that improvement of solder paste has an effect on mounting characteristics.

Discussions have been given on energy conservation, and reduction in greenhouse gas emission through efficiency improvement at the Uong Bi coal burning power plant in Vietnam. The Uong Bi power plant, which has become using coal of lower quality than the design value, has had incomplete combustion, resulting in increase of unburned components in ash, and decrease of the boiler efficiency to 65 to 70%. Clinker hopper troubles have been occurring frequently, causing plant shutdown at a number of times. The turbine efficiency also shows as very low value as 26 to 27%. The plan has envisaged replacement of combustion parts of the boilers, withdrawal and replacement of the turbine generation systems, new installation of electric dust collectors, modification of the ash treatment system, additional installation of the re-circulation system, new installation of waste water treatment facilities, and modification of the waste water treatment equipment in the plant premises. As a result of the discussions, the annual energy saving quantity was found to be 62,936 tons of crude oil equivalent for the case where only one turbine is renewed, and 93,298 tons for the case where both of the two turbines are renewed. The annual reduction quantity of the greenhouse gas emission was found to be 251,215 tons and 372,402 t-CO2, respectively. (NEDO)

This paper reports the site surveys in fiscal 1999 on the energy consumption efficiency improvement in the north-western part of China. Although blessed with affluent natural resources, the regional development is delayed because of geographical restrictions and harsh climate conditions. Power generation facilities include hydroelectric power plants with output of 7.81 million kW, thermal power plants with 13.89 million kW, and power wind power plants with 70 thousand kW. The demand is estimated to increase by 4.6% annually in average. Thermal power plants are those made by the former Soviet Union, having poor power generation efficiency, which is scheduled to be improved by facility modification. Automation is also behind the times. These situations have brought about low reliability, delay in building electric power network in agricultural districts, and transmission wire loss (reducing 8.1% loss to 6% is planned). The electric power charge systems also have various problems. Environmental measures are also an issue. Dissolution of energy shortage as a result of developing the north-western area can be said a key to the future development of China. Xinjiang Electric Power Company is considering wind power generation as the center of new energy utilization. Representative facilities utilize affluent wind power available in the topography of the Tenzan mountain range in the suburb of Urumqi, the facilities being made of Denmark. Photovoltaic power generation is exiguous in realizability for the time being in terms of cost. Expectation is placed on fuel cells. (NEDO)

For the purpose of reducing energy consumption and CO2 discharge in a cement plant in Indonesia, R and D was conducted on new clinker cooling system, high performance kiln combustion system, and technology for steady kiln operation and control, with the fiscal 1999 results reported. In the research on the optimum clinker cooling system, a new type clinker cooling system (CCS) was developed in which air beams are applied only to stationary grate rows, in an air beam type clinker cooling system where cooling air is fed to each block, with grate plates used as the air duct. This year, in an actual machine testing equipment (capacity 2,500 t/d), the whole heat recuperation area was modified for the CCS, with the operation started since February, 1999, aiming at the optimal clinker cooling effect and high heat recovery efficiency. The heat quantity for the entire system showed a decrease of 60 kcal/kg in the heat consumption rate through CCS modification, kiln burner adjustment, etc. So long as the demonstration plant is concerned, design of a new type burner and study/design for the kiln stabilization were nearly completed.

The feasibility study was started upon a request made by the Iranian Ministry of Energy involving the No. 7 kiln of the above said company. It was then concluded, after assessing the degree of urgency of supply and demand and the magnitude of loss due to reduced production because of the on-site modification work, that it was not practical to begin the project immediately. Under the circumstances, various studies were made about the feasibility of modification of the whole production process of the No. 1 kiln through No. 7 kiln, and a procedure was presented, to be described below. The procedure will consist of Phase I wherein the No. 3 wet kiln is converted into an NSP (new suspension preheater) dry kiln, Phase II wherein the No. 7 SP (suspension preheater) dry kiln is converted in to an NSP kiln, and Phase III wherein the No. 4 SP dry kiln is converted into a clinker cooler. Under this procedure, the modernization of the Tehran Cement Co., Ltd., facilities will be accomplished without causing production loss. After the completion of the project, an annual yield of 3.6-million tons will be achieved, with productivity to be improved by 26.4% over the current theoretical capacity or by 54.8% over the actual average for the past 5 years. There will be a sustained conservation of 25,356 tons/year in terms of oil. Application of CDM (clean development mechanism) to this project will be extremely effective in reducing greenhouse gas and in improving profitability. (NEDO)

As to the Bobovdol thermal power plant, Bulgaria, a plan for repair of power plant was worked out with the aim of energy conservation and greenhouse effect gas emissions, and the results of the feasibility study were reported. The existing power plant, 3 x 210MW unit, totals 630MW, approximately 130,000 hours in cumulative operation hour. In the repair plan, the plant is replaced with high efficiency gas combined cycle power generation facilities based on gas turbines by scrap and build. In the plan, the repair of existing units Nos. 1 and 2 for life elongation is urgently conducted, and new facilities are to be built every 5 years. As a result of the study, the energy conservation effect will be reduced by 16.37 million toe tons in 41 years after the repair, and the CO2 emission will be reduced by 105.18 million tons in 41 years after the repair. As to the profitability, the internal economical profitability is 5.66% in case of setting the CO2 emission trade at zero. This is the level on which the project is barely profitable by soft loans raised by Japan Bank for International Cooperation (JBIC), etc. (NEDO)

An investigational study was conducted of a project for energy conservation and greenhouse effect gas reduction by introducing the steam injection gas turbine generator to production facilities of the Siam Cement Industry Corporation (SCI) in Thailand. In the project, studies were made on the following: no purchases of electric power by introduction of the steam injection gas turbine generator; additional heating by gas turbine exhaust gas by introduction of the kiln combustion air heater; remodeling of the preheater of raw materials, and the partial calcination before kiln sintering by introduction of the calcination furnace. As a result of the study, the energy conservation amount was 1,200 toe/y, and the greenhouse effect gas reduction amount was approximately 8,000 t-CO2/y, which led to the reserve power for increased production of clinker by about 18%. The size of investment was 314.5 million Baht in total. As to the evaluation of economical efficiency of the investment, the actual period of ROI was a little less than 5 years, and the internal earning rate was 17.7%, which substantially met with SCI's standards for equipment investment. However, there are problems on the gas supply infrastructure, recovery of the white cement demand, etc. (NEDO)

The R and D were carried out on a system by which the long life of coolant of machine tools can be achieved and a system to process waste efficiently, economically and with less environmental loads, and the FY 2000 results were summed up. In the R and D of a system to prevent degradation of low energy coolant, measurement was made of effects of the degradation prevention system at a laboratory level, and it was found out that propagation of bacteria causing the degradation can be prevented with pH kept high. Further, it was admitted that the alkali effect on metal formability was not very much. As to the coolant processing, in the present situation, most of the coolant is taken back by industrial waste processing dealers. So, the development of the low energy waste liquid processing system is earnestly desired. In the R and D of the low energy waste liquid processing system, test on characteristics evaluation was conducted about each method of systems. Subjects to be improved/solved were extracted such as the point that volatile organic matters are included in condensed water after evaporation of waste liquid and there seems to be a possibility of needing the secondary processing.

Operating a 50 t/d fixed bed pilot plant, hydroprocessing of de-ashed coal liquid bottoms (DAO) derived from Victorial Brown coal liquefaction has been carried out in Australia using a newly developed Ca-Ni-Mo/Al {sub 2} O {sub 3} catalyst. This catalyst has a great advantage compared with conventional molybdenum catalysts in that there is less coke formation using this catalyst as indicated by 5,000 h runs in a 0.1 t/d bench scale plant. In this paper, the catalyst active center and the role of Ca in the Ca-Ni-Mo/Al {sub 2} O {sub 3} catalyst were analyzed using Raman, TPS-XPS, EXAFS and AES methods. Molybdenum is loaded as CaMoO {sub 4} and X-ray diffraction data. But the oxide is changed to MoS {sub 2} after sulfiding treatment. Data of the Mo-S bond obtained from EXAFS analysis indicated that MoS {sub 2} has a tendency to pile up on the Ca-Ni-Mo/Al {sub 2} O {sub 3} catalyst. 20 refs., 12 figs., 5 tabs.

In order to improve the existing design-supporting system for offshore structures, new functions are added to evaluate information of the products, especially those for structural designs. The structural analysis system should be provided with a function of design modification, to efficiently support the structural analysis of these structures. The new system adds hierarchy of various offshore structure models and three-dimensional dimensions to clarify structural and geometrical constraints and design-modification function. The design-modification function is included by use of the hierarchy. The other new functions are finite element analysis systems for the main structure and components, and rigidity calculation for the main structure. The main structure and functional element models are confirmed to be useful also for utilization of information, and provide necessary information of the product models. 11 refs., 11 figs.

This paper describes the achievements in fiscal 1999 on development of a basic technology to design and fabricate an innovative light-weight structure. Taking CFRP and aluminum alloy having excellent specific strength as the main object materials, weight reduction and reliability enhancement in aircraft structure are intended, while reducing largely the number of parts. In particular, the wings, the nose and the leading edge construction of civilian aircraft are of the structure assembled with a large number of parts, and are suitable as the research objects. A new conception will be introduced that structural members are fabricated by utilizing the characteristics of integrally formed CFRP, which will be assembled into a whole structure. Large structural metallic members currently used have such drawbacks as the use of great number of parts, complexity in manufacturing processes, low reliability, weight increase and corrosion due to rivet jointing. In order to solve these problems, development will be made on technologies for thin-wall large-size precision casting, and high-accuracy high-quality welding. To combine different kinds of members, and optimize strength, weight and economic performance of the entire structure, high-efficiency integration technologies will be discussed, and prototype full-size structure will be fabricated. The current fiscal year has started up the technology committee and its operation, analyzed technological problems in the entire structure, and established the action programs. An investigation was performed on the technological trends in overseas countries. (NEDO)

During ultrafine structure formation due to transformation from austenite to ferrite in an intense magnetic field, the transformation is accelerated by the thermodynamic stabilization of the ferrite phase which is ferromagnetic. The application of an intense magnetic field works effectively during the generation of nuclei. When a magnetic field is applied during reverse transformation, a honeycomb 2-phase structure is formed oriented toward the direction of the magnetic field and, when the structure is vertically compressed, the recrystallized structure is made ultrafine effectively. In pearlite transformation, hardening occurs when carbon atoms supersaturated in density are introduced in the presence of a magnetic field gradient, and curing further promotes precipitation hardening. In a ferrite complex phase system, wherein ultrafine globular cementite is uniformly distributed, plastic instability becomes explicit in a tensile test. There is a good possibility that an ultrafine structure recrystallization model may be built by calculation, into which the distribution of energy stored prior to recrystallizing nucleus formation is incorporated. The profile of a conceptual process of off-line or in-line integration of heavy-strain process and intense magnetic field application has become tangible. (NEDO)

Considerations were given on the spark generating mechanism of graphite particles in molten salt polysulfide through experiments on Japanese sparklers. The firework composition mixed consisted of two kinds: KNO{sub 3}, S, amorphous carbons, charcoal and lamp black, and K{sub 2}CO{sub 3}, S, charcoal and lamp black. The main constituent in fire balls is molten salt polysulfide. The O{sub 2} generated from combustion oxidizes C and S, whereas the generated K{sub 2}CO{sub 3} reacts with S to produce K{sub 2}Sn. In the KNO{sub 3} system, the calorific power reaches the maximum with lamp black contained at 10-15%. This is thought because the K{sup +} expands the space between the graphite crystal layers making the oxidation to take place more easily into their inner sides. On the one hand, the calorific power reduced with the lamp black at more than 16% would be because the lamp black clogging the crystalline spaces restricting the oxidation. It is thought that condensation and decomposition of micro graphite crystals occur simultaneously in the fire balls. It is also believed that the micro graphite crystals jumped out as a result of gas pressure from inside the crystals generated with the progress of oxidation break off at once because of the resistance of air together with the effect of the K{sup +} in the salt polysulfide (mutual separation of each layer). 9 refs., 6 figs., 1 tab.

Investigations and discussions have been given on measures to improve energy conservation and efficiency at a power plant of Kish Water and Power Company (KWPC) in Iran. The site has high ambient temperature throughout a year, making the gas turbine power plant capable of generating power only at about 70% of the rated output, with the power generation efficiency decreasing. The project has analyzed the current situation at the plant, and evaluated different means that appear effective in improving the efficiency, including the gas turbine absorbed air cooling system, the steam injection system, and the combined cycle. As a result of the discussions, it was revealed that energy saving effect can be obtained at 145 TJ with the gas turbine absorbed air cooling system, 224 TJ with the steam injection system, and 1017 TJ with the combined cycle. The annual reduction of greenhouse gas emission due to the above energy conservation would be about 11 thousand tons, 16.5 thousand tons, and 75 thousand tons, respectively. However, the investment payback period would be about 2.45 years, 8.31 years, and 14.21 years, respectively. Therefore, the profitability does not appear very attractive because of low fuel unit cost. (NEDO)

This paper reports the wind power development field test project in the off-shore park in Daitocho Town in Shizuoka Prefecture. The annual average wind velocity was 4.2 m/s (at height of 20 m above the ground), where the facility utilization rates for 300 and 500 kW class plants were 15.1 and 16.7%, respectively. Both of the annual average wind velocity and the facility utilization rate do not meet the criteria established by NEDO. Although the location is adjacent to the Natural Park, there is no restricting condition for installation. The substation to which system linkage is to be performed is the Daito substation 3 km north of the planned location. The major load is the Daito Spa in the park facility. Ground bed at depth of 5 m will be used as the windmill foundation supporting bed. There is little electromagnetic wave hazard. The location is 380 m away from the nearest residential house, presenting no windmill noise problem. The amount of power to be generated was assumed 281,000 kWh. Specifications for nine models of 300-kW class windmills that can be introduced into Japan were discussed to select a model. The project cost was calculated to be 128.5 million yen. The construction cost will be 428,000 yen and the power generation cost 38.1 yen/kWh. Its economy is poor when the current unit price for surplus power purchase is considered, but the effect of enlightenment may be expected. (NEDO)

Out of the developments of high efficient boilers which have been continued since fiscal 1993, the paper reported the result of the development conducted in fiscal 1996. The oxygen combustion (the oxygen enrichment combustion including 100% oxygen combustion) decreases the amount of flue gas and reduces heat loss of the flue gas, and is also effective as NOx reduction measures. The experiment was conducted using testing furnace. The boiler efficiency rapidly increased with the increasing concentration of oxygen enrichment. In the pure oxygen combustion, the overall boiler efficiency of a 106% level (low heating value standard) is expected. Since the boiler wet flue gas is decreased, the NOx emission is reduced. The boiler can raise the combustion temperature with no fear of NOx and can be reduced in size. CO2 decreases in proportion to the energy saving effect. The development of a condensation flue gas heat exchanger is aimed at recovering heat down to the low temperature. Prediction of heat transfer in the steam condensation region becomes possible, and the size reduction can be expected. Dew point corrosion resistant materials were also selected. As to the high speed combustion control, a simple type using micro-processor was developed. Obtained were high speed, compactness, electric power saving, and high controllability. 14 refs., 306 figs., 88 tabs.

This project started in FY 1993 to survey the actual state of industrial use boilers. Based on the results of the survey, in fiscal 1995, 1996 and 1997, no improvement of the present technology which has limits, but the development was made of the oxygen combustion and element technology which are factors for heightening boiler performance with a new idea first in the world. In fiscal 1998, a target for the overall thermal efficiency of 105% was settled by testing a pilot plant where the element technology was integrated into the small once-through boiler, flue/smoke tube boiler, water tube boiler, etc. In fiscal 1999, the target of the overall thermal efficiency of boiler was reached by a pilot plant test to clarify combustion characteristics, heat transfer characteristics, environmental characteristics, etc. Further, effects of energy saving were increased by the adoption method of oxygen supply equipment. Concretely, an overall boiler efficiency of 105.73% exceeding the targeted value of 105% was achieved at a pilot plant of actual scale, by concentrating the results of each of the element technologies such as 'oxygen combustion,' 'condensation type flue gas heat exchanger,' 'high performance combustion control device,' and 'rapid rotating auxiliary machine.'

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)

Moreover, it is an indoor system which shall have the operational characteristics to follow daily demand fluctuations while operating under the optimum conditions in the urban redevelopment area considered. A 5,000kW-class fuel cell plant burning fuel gas (2 yen/Mcal) will need a total floor area of approximately 400,000 m{sup 2} in an energy-intensive office type demand area. These conditions shall be met in order to economically introduce the 5,000kW-class plant. It is also necessary to compare the plant with the competitive cogeneration plants. The specifications for the prototype now under consideration are sufficient for the energy-saving effect, and it is premised that these specifications and characteristics are secured. (NEDO)

R and D was conducted for the purpose of manufacturing innovative iron-based alloy materials that excel in high temperature strength, toughness and superplastic forming, with fiscal 2000 results compiled. In the technological study on high-speed grain accumulation and superplastic forming, the researchers were engrossed in developing an aluminum bulk material of nano-crystals. This year, an Al-Fe two-element based alloy using Fe element was evaluated in the composition, thermal processing conditions and physical properties, with a bulk material obtained having a grain size of several tens in nm at 2at% Fe level, a strength of 750-850 MPa and a tenacity (Kc value) of 45-65 MPa(center dot)m{sup 1/2}. In the research of technologies for utilizing and controlling high density energy, design of materials was progressed for strong-acid resistant dew point corrosion materials, leading to the discovery of an alloy composition Ni-10Cr-5Nb-16P-4B whose subcooled liquid zone was wider than the Ta-added alloy of the previous year. Use of He gas as injection gas enabled a quality amorphous powder to be obtained in kg units. In the development of bulk amorphous producing technologies, this powder was thermostatically rolled to make a dense bulk amorphous plate of 2.8 mm thick and about 100 mm long. (NEDO)

Cuttings from a test drilling in the Kuenohira district, Oita Prefecture, are subjected to analysis. The result of ground surface investigation suggested the presence of a magma reservoir to serve as heat source and a highly permeable zone along a fault to help the formation of a thermal water retention system. At the N9-KH-1 drilling site, however, no geothermal reservoir is found along the periphery of the subsidence in the western part of the research area. In this district, it is deemed, no geothermal reservoir has been formed due to shortage of heat supply from the heat source and insufficient geothermal water activity. It is also deemed that the district, in which fractures of the E-W system, NNW-SSE system, and NE-SW system are distributed, is a region at which meteoric water flows into larger convection systems. As for the westward stretch of the geothermal reservoir (where the N9-KH-1 site is situated) that has developed on the swell of the basement, detected to exist at N2-MW-2 and N3-MW-6 in the eastern part of the research area, it is found to be not so extensive.

Upon the request from the Ministry of Agriculture of the Polish Government, a survey has been performed on three sugar production factories (Lesmierz, Lapy and Werbkowice) in Poland in relation with conservation of energy and reduction of warming gas emission. The survey has been made from the following two aspects: improvement of energy utilization efficiency in the sugar production processes, and efficiency improvement and fuel conversion in the boilers being the energy supplying source. As a result of the discussions on the sugar production process improvement, annual fuel conservation of 304,495 GJ (or 12,688 tons as converted to coal) in total for the three factories, or the energy saving rate of 28% was obtained. Regarding the greenhouse gas emission, an effect of reducing 25,235 tons, or a reduction rate of 27% was achieved. In the combination of the sugar production process improvement and the boiler improvement, the fuel conservation will be 18,363 tons as converted into coal, and the reduction of the greenhouse gas emission will be 56,107 tons. However, when based on the present coal price and natural gas price, the improvement efforts will not be realizable economically for both of Lesmierz and Werbkowice factories, hence comprehensive judgment is required from the viewpoint of the fuel price and environment preservation expense in the future.

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.

With an objective of saving energy and reducing greenhouse gas emission, a basic survey has been performed on the atmospheric crude oil distillation units and the high vacuum distillation units at Cilacap Refinery in Indonesia. The first site survey in September 2000 has carried out a survey on the situation of the facilities and operation upon obtaining the facility data and operation information from Pertamina. As a result, it was revealed that there is a room of improvement in the heat recovery, whereas a modification design was executed on the improvement proposals on the heat exchanger system. However, the second site survey in November 2000 has revealed that Pertamina had executed in 1998 through 1999 the de-bottlenecking project on the crude oil atmospheric distillation units (two units) and the high vacuum distillation units (two units), by which the capability has been expanded, and the heat recovery rate has been increased. It is not possible to look for extremely large enhancement of the heat recovery rate beyond that point, and the reduction of CO2 emission would also be small. As a result of discussions, the present project was found capable of reducing annually the CO2 emission by 36,500 tons. (NEDO)

The trend of the technology development in the Japanese iron/steel industry was compared with those in foreign countries and surveyed to increase the international competitive strength. From the viewpoints of technology, industry and goods, the iron/steel field was characterized based on the statistic data, and especially automobile use steel materials were selected such as cold rolling high tension steel sheet, surface treated steel sheet, and bearing sheet. The analysis of factors of competitive superiority was conducted, and the following were presented: measures for process continuation, and measures taken from the age of equipment and cost indexes. The paper also surveyed the trend of pig iron making/steel making technology in Asia. The present international technical competitiveness in the iron/steel industry in Japan, especially of automobile use steel sheet, is very high. This is because of the well-functioned demand-oriented development, and also as a result of the mutually influentially conducted equipment development such as process continuation and development of new goods, supposing the iron/steel continuous process and reduction in impurities. However, fears are the stagnation in the recent technical development strength and the saturation of new equipment. Moreover, the further heightening is needed of the international cost competitive strength of general-purpose products. (NEDO)

This project is aimed at surveys on the elementary and peripheral techniques necessary to construct the systems, with the objective to draw the conceptual designs of the total system for co-production of a substance and electric power. In a general reaction process, substances are produced under an advantageous condition that is dependent on reaction rate and equilibrium, where most of the energy is dissipated in the form of sensible and latent heat without being used for the chemical reaction. The co-production system under consideration uses high temperature of 500 degrees C or higher exhausted from a power station or industrial unit to produce macromolecules or synthesis gases, wherein the exothermic reaction increases temperature of the heat source, which is recovered in the form of steam for driving the steam turbine to produce electric power. On the other hand, low-temperature waste heat of around 150 degrees C is converted into a liquid fuel or other value-added products by the liquid phase pressurized system. The elementary techniques to construct these processes are surveyed, and the thermal processes are analyzed. The investigated items include substance production processes, electric power production processes and total systems. (NEDO)

As a project contributing to reduction in greenhouse effect gas emissions by introducing energy conservation technology of Japan to India and to sustainable economic development in India, study of 'conversion of raw materials in fertilizer plants in India' was made, and the results were reported. The Indian government has been controlling the retail price of fertilizer by the subsidy policy for the protection of the domestic fertilizer production. Therefore, plants, which use coal/heavy oil/naphtha with much greenhouse gas emission as raw materials, have been behind improvement and now have no competitive force in the international market. In this project, concerning ZIL's fertilizer plant, the ammonia production capacity was set at 750 t/d and the urea production capacity at 1,300 t/d, and the energy conservation technology and the conversion of raw materials from naphtha to natural gas were studied. As a result, the amount of energy conservation was 55,705 toe/y, and the amount of CO2 reduction was 245,139 t-CO2/y. Further, this project indicated that profits were expected to increase and the cash flow would change for the better. (NEDO)

On the basis of Kyoto Protocol-provided flexible measures such as joint implementation and clean development mechanisms, a study is conducted for introducing combined cycle into Konakovo Power Plant of Russia currently equipped with antiquated eight 300MW power plants constructed in the 1960's for which early renovation is necessary. The power station is an important power source connecting to the Moscow-Petersburg main. The gas turbine combined facilities to be newly installed will comprise 250MW-class state-of-the-art gas turbines arranged in four blocks, capable of a total output of 1600MW at a thermal efficiency of 58% (with simultaneous supply of heat). Four units capable of 1200MW out of the existing units will stay in operation for load adjusting. Since the price of power is set low under government control, the accounting capital/internal return rate is as low as 2.3%. The rate recalculated under the financing conditions of special yen credit for environmental protection, however, is as high as 19%, so high as to make the renovation an economically feasible project. It is expected that there will be an annual CO2 reduction of 2.3-million tons or a reduction of 57.50-million tons in 25 years (the life span of the new facilities). The renovation may be a joint implementation project to which both Japan and Russia will attach the highest priority. (NEDO)

In Oman, electric power supply is made by operating a large number of gas turbine generators. However, the operation is inefficient as a whole as a result of operating the generators provided with large reserves to minimize effects of unit failures in each power plant as one unit. Therefore, the present investigative study has begun from discussing the achievement of energy conservation and reduction of greenhouse gas emission by managing the demand and supply in an economical manner upon introducing a central load dispatching center (CLDC). Given the introduction of CLDC, the effects of introducing the equi-{lambda} method with still higher economy and of introducing the control system of reserve operation power may be summarized as follows: the energy saving effects (converted to crude oil quantity) are 22,400 toe/year for the former case and 35,800 toe/year for the latter case; and the greenhouse gas reduction effects are 52,000 t-CO2/year for the former case and 84,000 t-CO2/year for the latter case. This is an effective project with a considerable amount of effect as a result of introducing the equi-{lambda} and of introducing the control system of reserve operation power, while the investment amount is relatively small. The investment recovery period is 2.5 years and 2 years, respectively, making the project considerably promising as a CDM project. (NEDO)

The acoustic excitation of a plane diffusion flame enhances the periodicity of organized eddy controlled combustion. In this study, to clarify an effectiveness of application of active combustion control, phase characteristics of the excited eddy flames with high periodicity have been examined. A computer-aided phase-locked averaging method was employed to obtain graphical two-dimensional contour maps of the instantaneous profiles of temperature and CH emission. Both maps consisting of eight consecutive phases indicated clearly not only the periodic behavior of the organized eddy flame, but also the gas dynamic properties peculiar to those flames with coherent structure. In addition, the profiles of local contribution of the sound field to the combustion process were examined by calculating the two-dimensional distribution of the local Rayleigh index. Calculation results of the two-dimensional distribution of the local Rayleigh index indicated that the organized eddy flames have high sensitivity to sound, and play an important role in an interaction of sound and flame. 6 refs., 9 figs.

For the purpose of developing iron/steel materials which enable remarkable improvement of maintenance loads and longevity of oil field developmental materials, study was conducted for remarkable improvement of strength and corrosion resistance by making crystal grain of iron/steel materials micro-fine to the limit, and the FY 1999 results were summed up. The study was conducted on the technology of fine structure formation using strong magnetic field and technology to predict material quality of micro structure using computational science. As a result, it was found that the fine grain even in size can be obtained by a combination of magnetic field orientation and recrystallization. By this, an image was constructed of the industrialization process of fine grained steel production which was combined with warm rolling process and applied strong magnetic field. Using the method to homogenize the finite element method, the basement was established for the method to evaluate an effect of the second phase on mechanical characteristics of fine multi-phase structure steel. The cementite single-phase film which is an important structural phase of carbon steel was successfully formed, and the Young's modulus and Poison ratio were determined as basic data for material design.

Structure and velocity measurements using magnetic resonance imaging (MRI) have been performed experimentally to obtain a correlation between pore structure and interstitial flow through the packed bed of 5 mm diameter in the tube of 36 mm ID. To measure axial velocity maps of water flow through the packed bed, the phase method of using the phase difference of water spin magnetization between flowing and stagnant fluids by applying magnetic fields with bipolar gradients was employed. The spatial resolution of the obtained map in 0.2 mm x 0.2 mm x 0.5 mm. It was made clear from the obtained axial velocity maps that channel flows with higher axial velocity were induced not only near the wall but also in the internal region of the packed bed. Furthermore, pore structure of the packed bed was characterized from multi-slice images by partitioning of void space and combining of each pore section along the axial direction to analyze the structure-flow correlation. It was found from image analysis that axial channels with long and straight void space existed in the pore structure, and that most of the channel flows with higher axial velocity were induced in the axial channels. The flow rate through an axial channel depends on the square of the averaged cross section of the axial channel. (author)

R and D on harmonized molecular materials aim at establishment of the technology fabricating self-assembled organic molecular films on solid surfaces which have potentials of mechanical response to electric fields, electroluminescence or optical functions. Molecule harmonization expresses new structures and functions difficult to be expressed by each molecule alone, by cooperative interaction between molecules due to noncovalent bond. Functional thin films were developed by controlling alignment and/or arrangement of molecules with an aid of self-assembling processes. Thiol compounds with larger dielectric anisotropy were synthesized as electric field responsive self-assembled films. {pi}-conjugated compounds composed of phenyl-capped oligothiophenes were synthesized as electroluminescent self-assembled films, and their high crystallinity and efficient electroluminescence were found. Heat- and solvent-resistant lyotropic liquid crystalline (LLC) aligning polymers such as polyamine and polyimine were synthesized as new optically functional LLC dye self-assembled films. (NEDO)

In the Asian region, for the purpose of grasping effects of both economic growth and effective energy consumption, an analytical tool added with a computational function was developed with the interindustrial relations table as database for the analysis of the present situation and the simulational analysis. In the analysis of the present situation, changes between the two time-points, 1985 and 1990, were analyzed using the developed energy consumption table and the CO2 emission table. The energy consumption amount is increasing with the growing economy. However, the energy unit consumption is decreasing in countries except Korea, the Philippines, Singapore and Malaysia. The trend is that the energy consumption is becoming effective and the CO2 emission amount is decreasing. As an example of simulating the introduction effect of energy saving technology, the simulation was conducted on the three: iron steel, paper/pulp, and cement in Indonesia. As a result, the decrease in energy consumption was shown in paper/pulp by 48%, in cement by 16%, and in iron/steel by 16%. The same was also indicated in CO2 emission. (NEDO)

For the reservoir evaluation at an initial developmental stage and stabilization/maintenance of power after the start of operation, the fiscal 1997 result was described of the study of technology of prediction of reservoir variation. Using the conventional post processor, feasibilities were computed of reservoir models and behavior after the development, and gravity/self potential/resistivity variation. Variation in the seismic wave speed structure was large in travel time change distribution. The measuring accuracy of 1m sec is required to get enough detection resolving power. A conceptual design of the post processor development was conducted to study a system operated on Windows. Based on the reservoir numerical simulation technology, by taking in variation parameters such as gravity and self potentials as new model constraint conditions, the reservoir modeling technology which increased in accuracy by history matching was trially developed. Using the conventional reservoir model in the Oguni area, predictably computed were reservoir behaviors during 50 years which simulated a 20 MW development. Effectiveness of the post processor were able to be shown though influenced by characteristics such as permeability and resistivity. 74 refs., 95 refs., 12 tabs.

A large quantity of coolant is used in the grinding process for ensuring high accuracy and quality in the work. This presents a serious problem from the viewpoint of environmental impact or energy conservation, and now environment-conscious grinding methods requiring no or less coolant are sought for. With a view to answering the demand, efforts are exerted to put to practical use, and improve, an EcoloG grinding technique. The goal is to reduce to half the energy that the grinding process is now consuming. The EcoloG technique is a grinding method under which vegetable oil mist is cooled for lubrication and a small amount of cooling water is fed to the point of grinding for removing chips. In fiscal 1999, a survey was conducted on technical literature, patents, and the like in and out of Japan for the study of the actual state of dry machining, and then the course of future studies was clearly established. Studies were also carried out aiming at the practical application and improvement of the EcoloG grinding technique, and the technique achieved a quality level as high as that of the conventional coolant-aided method in a process of grinding a shaft to have an accurate outer diameter by use of an ordinary wheel head.

This technological development is intended to develop a process technology to dispose adequately of air bags convergently when they are removed from waste cars, with consideration paid on environmental and safety aspects. This technology that can dispose of air bags remaining as air bag modules (ABM) in large quantity and adequately can solve the problems of maloperation in opening them in cars and noise in conventional disposal methods. The recovery and disposal system using an inflator can be expected of reducing work load on dismantling contractors and enhancing the work safety. Furthermore, the energy saving process utilizing combustion of plastics can save resources. However, this technology has not elucidated how dioxins, dust, smoke, sulfides, and nitrogen oxides are generated and how the generation can be prevented. Therefore, an exhaust gas dioxin testing facility and an exhaust gas treating facility were installed additionally to the existing heating treatment facility to develop a disposal technology to treat adequately the exhaust gases generated when ABMs are disposed conveergently in large quantity, and treat the waste water discharged from the facilities. Fiscal 1998 has performed preliminary tests to accumulate fundamental data, and design and installation of the above two facilities. (NEDO)

A study was made on effects of fluctuation of the exchange rate on business activities in the iron/steel industry. Fluctuation of the exchange rate is an uncertain element in working out a plan for future business activities, and hinders research development and equipment investment to be positively made. In the iron/steel industry in Japan, the rate of yen basis in trade settlement currency is especially lower than in other industries, and has a constitution which is easily influenced by yen appreciation. However, the iron/steel industry is an industry exporting products, and at the same time, is an industry depending on import for most of the main raw materials. Accordingly, the yen appreciation not only has negative effects, but has different effects, depending on the rate of shifting the amount of exchange rate fluctuation to local price, and on conditions of the rate of realizing price lowering which means that the exchange rate fluctuation reflects the lowering of imported raw material prices. If only these conditions are fulfilled, the yen appreciation even produces rather favorable effects in the iron/steel industry. In the circle, the conversion of the structure is being expedited for converting effects of yen appreciation to beneficial ones. Financially, exchange risk management is also necessary. 41 figs., 35 tabs.

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.

Development is intended to be made on fundamental combustion control technologies applicable to high-performance industrial furnaces that can reduce energy consumption and respond to environment preservation requirements. With an intention to achieve reduction in combustion exhaust gases such as carbon dioxide and nitrogen oxides, fundamental studies will be made on factors to decide flame shapes as represented by high-temperature combustion and flame shape control by utilizing microgravity environment, and researches will be made on combustion systems. Devices required for the experiments were fabricated to evaluate critical combustion characteristics of flames in furnaces including industrial furnaces, analyze and evaluate flame control parameters, and study low-pollution combustion technologies. Experimental methods acquired by 1997 were used for the experiments under the microgravity environment. Evaluation experiments were performed on flame shape control technologies and flame radiation characteristics, and basic experiments on the low-pollution combustion technologies. With these experiments, elucidation of the combustion mechanisms was launched by analyzing and evaluating the acquired data. A flame experimenting device for high-temperature preheated air completed by fiscal 1997 was used to acquire such combustion characteristics data as NOx discharge characteristics when the high-temperature preheated air is used. Based on the result thereof, verification was carried out on simulation models. (NEDO)

Myanmar generates majority of the whole electric power by using thermal power plants consisting of single gas turbines, and gas and steam composite turbines. However, because of chronic power shortage and fund unavailability, the major gas turbines are being operated in quite inadequate environment. As a result, reduction in power generation efficiency has become manifest due to aged deterioration, increasing the quantity of CO2 emission. The present project is, in order to link it to the 'Clean Development Mechanism' being carried out with developing countries, and placing Tharkayta Power Plant as the object, intended to comprehensively discuss a rehabilitation program to renew the existing gas turbines with advanced ones, in relation with feasibility of the project implementation including the effect of CO2 emission reduction, profitability, and proliferation effects. A prospect was acquired that, by replacing the gas turbines alone with 25-MW class gas turbines, the plant output will increase to 97.2 MW (78.5 MW in the existing facilities) and the plant efficiency to 43.3% (36.5% in the existing facilities). The energy saving effect during a period of 40 years would be 708,000 (toe) as heat consumption converted to crude oil, and the CO2 emission reducing effect would be 2,160,000 (t-CO2), respectively.

With an objective of saving energy and reducing greenhouse gas emission, investigations and discussions were given on modification of Cherkassyoblenegro Combined Heat and Power Station in the Republic of Ukraine. The project calls for shutdown of the first block and the heat supplying auxiliary boilers being the oldest facilities in the existing station, and utilization of the second block for emergency use. The new facilities will consist of natural gas burning gas turbine combined cycle cogeneration facilities of 200-MW class including two gas turbines, one steam turbine, two each of waste heat recovery boilers, ducts and stacks. As a result of the discussions, if the project execution period is set for 20 years, the energy saving effect would be 144,215 tons of crude oil equivalent annually, and the greenhouse gas emission reducing effect would be 431,421 t-CO2 annually. The total fund amount required for the project is estimated to be 185,700,000 dollars. With regard to the profitability, the internal profit rate for the total fund after tax would be 8.3%, and the principal and interest repayment multiplying factor for single year would be greater than 1.9, whereas the profitability can be anticipated if the financing is available under generous conditions.

Discussions were given on the modification plan for Atyrau Refinery in Kazakhstan as a basic survey on promotion of joint implementation based on the COP3. The plan is intended mainly on modernization of overaged refineries, energy conservation, and prevention of pollution. The gists of the plan consist of improvement of quality of diesel oil and gasoline, reduction of production ratio of fuel heavy oil, plant efficiency enhancement, and environmental improvement. The crude oil selected in consideration of the demand in market was the light-gravity Tengiz crude oil whose production increase was attempted. For product quality, a plan was established to modify the facilities to realize improvement in content of light oil, sulfur and aroma, production of non-leaded gasoline, and octane value improvement in consideration of exporting the product into European markets. Since this project is applied to a private corporation, it is necessary that the project is commercially viable. However, the commercially low profitability makes the implementation of the project difficult unless such conditions as crude oil price and product sales price would be improved largely. Effect of the carbon dioxide gas reduction as a result of the implementation would be 180,000 tons annually, but in terms of cost effect, the implementation requires an investment of 500 Dollars per ton of carbon dioxide, thus the effect is low. Reduction in other greenhouse effect gas is not large quantitatively. (NEDO)

There has been tried to apply unified assessment method using hot spot stress, which is effective to evaluate fatigue strength of fillet welded structures for ships and marine structures. This method can be applied to complicated structures and is independent of welding processes. In this study, first, stress analysis has been conducted for two-dimensional fillet welded joint models with various combinations of plate thickness and weld leg length of general fillet structures by means of boundary element method. Then, critical position, which is not affected by local stress concentration due to bead, was determined from the detailed stress distribution in the vicinity of weld toe. As a result, a general equation has been proposed to estimate the hot spot stress by one-point representative method. Second, the fatigue tests of typical fillet welded joints have been conducted by applying this method. Consequently, it was demonstrated that the unified fatigue strength can be evaluated by the S-N data based on hot spot stress range determined from the proposed equation, independent of structural stress concentration. 22 refs., 14 figs.

A report was made on the 1998 results concerning technological development of super metal. In the 'research and development of super metal', metallurgical examination has been made on crystal grain super refining process using a machining simulator, with studies carried out on crystal grain refining by utilizing large-strain deformation with more than 50% deformation for a single pass and a diploid structure. As a result, it was found that the crystal grain size can be refined to approximately 1{mu}m. Consequently, in fiscal 1998, a high-speed large reduction rolling test equipment was developed capable of rendering a sheathing technology in a mechanically testable size by a rolling method. This test equipment has such capacity as the maximum load of 1,000 ton and the maximum torque of 95 ton/m and is a rolling mill whose scale is largest in the nation on the laboratory level. The rolling speed can be 120mpm, a very fast speed for a large sized rolling mill. Moreover, equipped with an immediate water cooling facility adjacent to the rolls and an automatic operating system for example, it is a high function rolling mill capable of cooling and rolling that render the complex and delicate sheathing technology of super metal.

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)

Described herein are the results of the FY1994 research program for energy conversion technology using chemical reactions by the aid of solar energy. The demonstration runs were conducted by a bench-scale unit, which was operated stably for 100h, to produce promising results. The catalyst exhibits stable performance, without showing a sign of deactivation. It is found that the heat pump system works well, without being interfered with accumulated by-products. A heat of approximately 2,100kcal/h is recovered. It is confirmed that steam of 150{degree}C and 200{degree}C is generated from hot water of 80{degree}C and 95{degree}C, respectively. The bench-scale runs show a thermal efficiency of around 10%, which is lower than the target level. However, the runs with hydrogen-occluding alloy attain a process thermal efficiency of 30%. The system in which solar collector and chemical heat pump units are combined is evaluated with respect to its economic efficiency and operability for its eventual commercialization. 6 figs., 2 tabs.
