    The paper described the results of the FY 1999 research on the fouling by marine aufwuchs. The survey is aimed at searching the nature world for active substances for biological antifouling. The fouling mechanism in the ocean is as follows. The adsorption of organisms called the conditioning film first occurs on the surface, and next, bacteria and diatom around the surface form biofilm and cover. After that, biological fouling by large aufwuchs occurs. Therefore, the control of biofilm formation was regarded as most important, and with this as a guidepost, the search was conducted. Using biofilm anti-formation activity and periphytic bacteria anti-growth activity as guideposts, some compounds were searched for. Being aimed at Porifera, in particular, new compounds were isolated from it. Since few of other organisms attaches on the surface of sponge, there is a great possibility of Porifera's producing any anti-fouling substances. Further, it is thought that symbiotic microorganisms of sponge (40% of the total weight) produce various biologically active substances. Synthetic phenethyl amine derivatives were also studied.

    This paper describes cooperative development of bio-treatment technology for mine waste water generated by operating mines in China. Certain types of bacteria have capability to oxidize ferrous iron in the waste water into ferric iron ions. The bacteria cause ferric iron oxides in low pH regions to get deposited, and can remove them from sedimentation by using cheap calcium carbonate as a neutralizer. Volumetric reduction in waste sediments may also be achieved during removing heavy metals in a pretreatment process. Great advance may be expected in taking actions to prevent water quality contamination. This paper summarizes activities taken in fiscal 1998. Eight site surveys in total were carried out using 47 persons in total. Major activities included operation study guidance of a pilot plant, and surveys for measures on heavy metal generation sources in Wushan Mine. In addition, site surveys were performed at Dexing Mine and Yinshan Zinc Mine. Subsequently from fiscal 1997, a bench scale testing equipment used in Japan and consumables were transported to China. The operation study data on the pilot plant were put into order and analyzed. Concept design was also made on a waste water treatment facility for Wushan Mine. (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)

    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.

    A study is conducted on an energy supply infrastructure for introducing a cogeneration system into the Yumesu district, which is a key point for the development of Osaka City, so that environments suitable for the 21st century will be formed and sustained. In the study, plural heat supply systems are discussed for the district. Taken up also are the possible utilization of heat from the waste incineration plant to be constructed on the neighboring Maisu island and of hitherto-unexploited energy sources such as seawater and the sewage treatment plant whose construction is now under consideration. Findings are that every method under study achieves an energy-saving rate of 5% and that the introduction of an urban type power plant will obtain the best result marking an approximately 22% energy-saving rate when its exhaust heat is effectively utilized. The order remains the same when their environmental features are surveyed, with the urban type cogeneration system holding first place with a NOx reduction rate of 37.7%. When it comes to economy, however, the method of effectively utilizing the exhaust heat from cogeneration power plants installed at consumers' marks the best result, this attributed to the low cost of pipe laying in the district.

    This survey studied the feasibility of large-scale offshore wind power generation in Japan. Attempt was also made on preparation of outline maps of offshore wind around Japan. The cost of future offshore wind power generation systems is roughly dependent on technical issues and environmental issues. As technical issues, 'installation site,' 'foundation,' 'system interconnection' and 'maintenance/management' were summarized based on applications in Europe. As a result, it was clarified that technical issues can be solved with existing technologies to a certain extent, however, those relate to economical problems closely. The previous environment impact assessments say that wind power generation has no problems on the environmental issues. As relatively strong wind coastal areas, the outline maps of offshore wind point out Western Hokkaido area, Japan Sea area of Tohoku district, Pacific ocean area of the central part of Honshu, Genkai Nada area, Western Kyushu area and Southwest islands area, and suggest that these areas are promising for offshore wind power generation.

    Discussions were given on the new energy vision at Gushikawa City in Okinawa Prefecture. The energy demand in Gushikawa City is estimated as 829.3 billion 73 million kcal, which is about half of the national average per population. By departments, the consumer department has a very large demand of about two times as much as the national average, while the demand in the industrial department is as low as about 38% of the national average. The energy demand by kind is in the order of electric power, gasoline and heavy oil. With respect to energy supply, the Okinawa Electric Power Company Gushikawa Power Plant supplies 561.60 billion kcal. The expected new energy availability is estimated as 47087 x 10{sup 3} kWh/year by solar energy power generation, 7174 x 10{sup 3} kWh/year by wind power generation, 1662 kWh/year by ocean wave power generation. Wastes energy availability is estimated as 74990 x 10{sup 6} kcal/year in the sum of general and stockbreeding wastes energy. Specific plans discussed introduction of solar energy power generation and small wind power generation systems to primary and middle schools, gymnasiums, urban area redevelopment projects, coastal parks, street lights, low-temperature warehouses, prefectural hospitals, and multi-purpose welfare centers.

    On energy consumption in a residential sector, the report reports the document survey result including new documents, and the result of the systematic national questionnaire survey carried out in small and medium cities to prepare the basic data for future development and introduction of petroleum substituting energy. The electric power consumption rate of detached houses (A) is larger by 0.6- 1.6Gcal/household/year than that of apartment houses (B) in every district. The gas consumption rate of A is smaller than that of B in Hokkaido, Kanto and Kyushu. The LPG consumption rate of Kinki district is largest in both A and B. The kerosene consumption rate of A is larger than that of B. In Hokkaido, the kerosene consumption is extremely large in heating, showing a ratio of 60% or more in A. In the other districts, the kerosene consumption is largest in hot water supply, showing 30% or more. Every consumption rate increases with annual household income. The average consumption rate of 4 districts is 11,137Mcal/household/year. (NEDO)

    Feasibility of commercialization is discussed of an environmentally friendly heat supply system for the above-named district. The research centers on the configuration and optimum dimensions of heat source equipment for a large-scale cogeneration-aided district heat supply system to be selected for introduction into the district. Discussion is made about the energy efficiency and environment preserving features of a system selected for employment. A study is then conducted on a plant consisting of two high-efficiency 4800kW gas turbine cogeneration systems and heat storing water tanks. Such when introduced will contribute to the levelling-off of urban power loads and to the enhancement of power peak cut through the utilization of cogeneration system-generated power and midnight power. When the exhaust heat from the cogeneration system is fully exploited, the system will achieve an energy saving effect approximately 9% higher than that exhibited by separately functioning heat source systems. Furthermore, CO2 will be reduced by 20% or more, NOx by 45% or more, and SOx by 46% or more, as compared with separately functioning heat source systems. The conclusive evaluation is that the above-selected system will sufficiently contribute to the preservation of environments. (NEDO)

    The need of new energy introduction is found in matters relating to energy security, resources depletion, environmental problems, and the construction of distributed energy sources. The total amount of new energy in the prefecture is 4,859,052Gcal (525,301kl in terms of crude oil), which occupies approximately 30% of the energy that the prefecture demanded in fiscal 1996. Out of the said new energy, those from the sun, wind, ocean, and small- and medium-scale water systems may be acquired in the form of electric power, and they add up to 3,615,424MWh (3,109,265Gcal in terms of calorific value, 336,137kl in terms of crude oil) and occupy 64% (including industrial wastes) of the whole amount. As for the percentage of each type of new energy, solar energy is the highest, its amount of 2,973,679Gcal (321,479kl) occupying 61.2% of the whole, followed by the energy from wastes whose amount in total is 695,131Gcal (75149kl) occupying 14.3%. The possibility of introduction of new energy is studied and the conclusion is described for each energy type, district, and sector (residential and commercial, industrial, transportation). The respects on which prudence should be exercised in introducing new energy are also discussed. (NEDO)

    Research was made to promote Activities Implemented Jointly Japan Program. Joint Implementation (JI) is the methodology for preventing global climate changes by collaboration of countries. The countries take cooperative actions for reduction, absorption and fixation of greenhouse gases, and effectively distribute the reduction credits among relevant parties. This was decided in the first session of the Conference of Parties (COP) held in March, 1995. In COP3, Japan`s assigned reduction amount in 2008-2012 was determined as 6% of the emission level in 1990. The protocol defines JI between parties as dealings of emission reduction units, and JI between developing countries as clean development mechanism. The rules for a base line and credit distribution are necessary before full-scale implementation. Although JI is regarded as an important cost-effective project, it is important to decide where and how the JI projects should been promoted. The present state and issues of the primary approved project of Japan Program are arranged. In particular, various terms related to developing countries remain to be solved. 21 figs., 32 tabs.

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

    Rapid economy growth has been observed in Asia including Japan. On the other hand, problems of population and environment grew even worse with the economic growth. Especially, China is the second CO2 emission country in the world. Large energy demand is still forecasted with its economic growth in the future. It is well-known that the energy consumption per unit GDP is very large. Therefore, it is very significant to promote the activities implemented jointly with China for mitigating the emission of greenhouse gases including CO2, which provides a significant meaning for solving global environmental issues as well as for improving regional environmental issues. It is necessary for the above to recognize the appropriate current situations and to promote the activities implemented jointly suitable for the country. Based on the discussions and information exchanges about environmental issues with staffs concerning environmental policies and scientists as well as the field surveys, methods for the activities implemented jointly were investigated to provide some proposals. 4 figs., 8 tabs.

    Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

    In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood. In this survey, was investigated the outline of patent systems of major countries to study about what should well balanced treatment of intellectual property in international collaboration research project be in the future. 4 figs., 8 tabs.

    The trend survey was conducted of global warming protection measures by participation in international conferences, scientific society meetings and lecture meetings, and by literature surveys. We participated in the international conference on ozonosphere protection measures. In the 9th meeting of the nations which concluded the Montreal Protocol, the strengthening of restrictions on methyl bromide was decided on. In the UNEP solvent technology selection conference and the OORG conference of the World Bank, reports were made on substituting solvents in Japan, activities supporting developing countries, and the developmental trend of urethane use foaming agent. In the international conference on ozonosphere protection measures, introduced were the present status of Japan`s ODA for developing countries and examples of success of the substitution in the solvent field. The paper included nine reports on CFC destruction technology related literature made public in the past one year. The paper also introduced a comparative study of de-HCFC substituting technology at U.S. Oak Ridge National Laboratory, U.S. EPA`s prediction of emission of fluorine 3 gas, the predicted value of HFC emission and trial calculation of contributing rate in all greenhouse gases by IIR, Green Peace and Elf Atochem, and NOAA`s measured data on SF6 in the atmosphere. 49 refs., 46 figs., 26 tabs.

    To cope with the global warming caused by CO2, an investigation was conducted into biological fixation. It is necessary to make a many-sided and comprehensive study on the mechanism of CO2 fixation, the scale (area and carbon holding density), the rate and the environmental impact of the introduction of the technology and the technical problems, and to make a quantitative evaluation of each of the methods in order to make them practical proposals. The global ecosystem is classified into the land biota and ocean biota, and each typical ecosystem was surveyed in terms of the surface area, the carbon holding amount (presently existing amount), the net primary production amount, the required nutrient salt amount, the transpiration rate, etc. Next, a discussion was made on the increasing effect of the carbon fixation amount by changing the present ecosystem from the aspect of scale and rate. At the same time, a study was carried out of energy efficiency, economical efficiency and problems. Last, elementary technology was taken up which seems to be important for implementing measures for the biological carbon fixation. As to the ocean, it is necessary to obtain information, which is not sufficient to utilize marine biota for CO2 fixation, especially on the mechanism of depth-direction transfer of organism and its quantitative grasp. As to the land, one of the measures is conversion of the ecosystem where the amount of carbon fixed is small to the ecosystem where the amount is large. 249 refs., 58 figs., 51 tabs.

    The result and evaluation of the geothermal development promotion survey in the Haneyama area were summed up. The geothermal development promotion survey in the Haneyama area was conducted in the area of approximately 300km{sup 2} of Kujuu-machi, Oita prefecture to make extracts through the ground survey and well survey of the high earth temperature abnormal zone in the north of the Houhi geothermal zone. The ground survey included the geology/alteration zone survey, density survey, geochemical survey, and electromagnetic survey. From the result of drilling six holes for the heat flow rate examination and the existing test boring data, the earth temperature distribution within this survey area was outlined. In the structural test boring survey, a maximum temperature of 140.6{degree}C was recorded at a depth of 1045m. The result of this survey indicated that the CL-SO4 type hydrothermal system in the Noya-Mizuwaketouge area probably extends near the south of Fukumayama. However, since the storage temperature is estimated at approximately 140-195{degree}C, the hydrothermal system is not expected to be used as resource for the steam power generation, but for the binary power generation. 98 refs., 144 figs., 92 tabs.

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

    Field research was made for oil saving in Thailand. To promote energy saving in a textile industry as main export industry, its motivation for production stuff is essential in business improvement. Proposal for work improvement, supply system of bonuses, and small-group activity are effective. Management of an energy consumption rate is essential in business management. Use of efficient waste water treatment equipment is also one of the issues. In food factories, various scopes for improvement are still found by mass/heat balance analysis in production process. As an example, a large amount of water is consumed in vain for washing raw rice in a rice powder factory, and separation of SS precipitate from waste water should be improved. Because of lagoon treatment, an effluent standard is not achieved in spite of consumption of wasteful aeration power. This treatment is reasonable because of its scale and site, although the standard can be achieved by activated sludge method. Reconsideration of the standard is also necessary based on a local total BOD load capacity. The profitability of a methane fermentation method should be examined. 72 figs., 95 tabs.

    As a part of the study on accelerated formation of bio- functions, analysis technology of experimental systems for in vitro evolution of protein molecules was studied. For the analysis, recognition of a fitness landscape is indispensable. Improvement of adaptive walk is possible through its analysis in an ordered space based on features of the landscape. By the last fiscal year, the knowledge of the fitness (heat-stability) landscape was obtained in the experimental system of PEP (prolyl endopeptidase) in which an adaptive walk mechanism was found to function effectively (mutated protein with a heat-stability effectively improved by adaptive walk was obtained). To obtain more general fitness landscape information, landscapes of various proteins to a fitness should be examined, and the effectiveness of approaches to efficient adaptive walk on the fitness other than a heat-stability should be clarified. The second experimental system using LOD (lactate oxidase) was thus constructed to examine the heat-stability landscape. In addition, the system of in vitro molecular evolution of proteinase inhibitor (Cystatin B) was constructed. 3 refs., 3 figs., 2 tabs.

The questionnaire survey selected 879 business entities involved in manufacture and sale of the welfare goods. The effective reply recovery rate was 19.3%. The questions had the data contents required by products classified into body dimensions, motion capability, sensory functions, and work capability, asking to state data contents required for each item, reasons for the needs, and data sources. The data source currently utilized reveals that most of the replied enterprises utilize data derived from the company's own measurements, developments and experiences. The contents thereof indicate that the data are too old, the data contents do not match the current situation, and no required data are available. In designing, developing and fitting the welfare goods, the required data may not necessarily be obtained, whereas improvement in the database is strongly desired. (NEDO)

    Reported herein are the survey results of hot water in the Kumaishi area, Hokkaido, as part of the FY 1996 geothermal development/promotion survey project. A total of 277 spouting guidance tests were conducted by the swabbing method for 10 days at the N7-KI-1 well, which, however, failed to achieve continuous spouting of geothermal fluid. A total of 144 swabbing tests were conducted for 8 days at the N7-KI-2 well. The geothermal fluid is spontaneously spouted out, although intermittently, after the main valve was opened, because it had a pressure of 4.1 kg/cm{sup 2} G at the mouth of the well from the first. However, the final self-spouting quantity remained unchanged in spite of the guidance works. The hot water had a pH 6.4, and contained Na as a cation at 8,940 mg/L and Cl as an anion at 14,500 mg/L as the major impurities. The associated gas was mainly composed of carbon dioxide, containing little hydrogen sulfide. The hot water spouted out through the wells contained Na and a high concentration of Cl as the major impurities, suggesting possibility of mixing hot water containing a high concentration of salt with surface water. It is considered that neither hot water nor its impurity concentrations are evenly distributed in the deep underground of the Kumaishi area. It is therefore considered that the deep underground hot water sources for hot spring slightly vary in composition and impurity concentrations. (NEDO)

    Under the project, an analytical tool applicable to the entire Asia-Pacific region is created. The tool enables the analysis of interrelations between economic/industrial activities and energy consumption in every country in the region, comprehension of the current status of energy consumption efficiency improvement, and analysis from a macroscopic viewpoint of trends in the Asian region as a whole, and thereby will contribute to the developmental enlargement of undertakings involving energy consumption efficiency improvement in the Asia-Pacific region. Based on 1990 Korean, Indonesia, Thai, and Philippine bilateral inter-industry relations tables, each vis-a-vis Japan, and energy input tables broken down by industry type and energy type, a database is prepared in which inter-industry relations tables and energy input tables are integrated. In conformity with the goals of the project, summaries are stated of the extraction of common classification, recombination of the Chenery-Moses inter-industry relations table, energy input table, and the CO2 emission table. It is found in a simulation that energy reduction in the four countries in 1990 amounted to 83,013 kilotons in terms of oil, equivalent to 25.7% of Japan's total endogenous energy consumption. It is suggested in the paper that the transportation department is the most important department for the industrial and energy-saving measures of the four countries. (NEDO)

    For the purpose of realizing `the affluence` sought in the Japanese economic society, the supply and preparation of products, service and environments friendly to human beings seem to be important. In the future, the development of products which are fully considered also of aged and handicapped people is more expected than the conventional manufacturing of products added with value. Especially in accordance with the rapid aging, from a viewpoint that the lowering of physical functions caused by aging has an exactly close relation with the response to products and the environment, development of the database of physical functions for the aged which is useful for the design is urgently promoted. First, the data to be supplied for database were selected. As to the selection method, the data required for database were defined by collection/analysis of the existing data, examination of the needs of enterprise designers, and analysis of daily activities. In the study of the database, the structure by which data can be effectively supplied was studied and verified by pilot database for extraction of the subjects and solution to the problems. 6 refs., 57 figs., 26 tabs.

    As to intelligent transport systems (ITS), the paper views the outline of the R and D and diffusion in Europe, the U.S. and Japan and trially estimated the effect of reduction in greenhouse gas, and worked out visions/scenario for diffusion of ITS. As developmental fields contributing to reduction in greenhouse gas, the following were taken up: 1) AVCS (advanced vehicle control system), 2) automatic rates receiving system, 3) traffic management, 4) plans of operation management/allocation of commercial cars, 5) modal shift of the material flow, and 6) public traffic in passenger transportation. As effects by developmental field, 1) and 5) are especially effective. 4) is promising because of its easiness in introduction, and 2) is also a promising technology as a tool to introduce an electronic road pricing system on general roads in future in addition to the effect of reducing heavy traffic by its introduction to expressways. However, the higher the service level on the facility side becomes, the more the traffic demand amount becomes. By how to introduce ITS, it possibly occurs that improvement of the situation will not be made at all on the future vehicle traffic system. 38 refs., 42 figs., 52 tabs.

    A large-scale cogeneration system will be introduced into the air-front industrial complex in the Izumizawa area having large energy demand within the city of Chitose well blessed with natural environment. The system will utilize natural gas locally produced in the Tomakomai Yubarai area (the utilization produces 20% reduction effect of carbon dioxide emission even only from conversion from petroleum oil). At the same time, heat supply operation will be carried out meeting the heat demand in diversified consumer applications, such as air conditioning of ancillary facilities, hot water supply, hot bathing facilities, and snow melting. Business feasibility has been investigated and discussed. Discussions were given on gas engine, gas turbine, combined cycle, and steam jetting systems. Although the combined system was found most superior, other cases present no large difference excepting the turbine system. The system is a highly efficient energy saving facility (annually saving 3000 kiloliters of crude oil, worth for annual kerosene consumption by 1500 ordinary households in Hokkaido). It can largely reduce emission of carbon dioxide. Each case has large economic effect with the simply calculated number of years of return of investment being six to eight years. (NEDO)

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

    In energy utilization in the 'Kawasaki Zero Emission Industrial Complex', optimal regional heat supply systems were discussed. The discussion was made from the viewpoints of introduction of saving-type energies, new energies and renewable energies, and environment preservation performance. The coastal area in the Kawasaki ward is planned of developing an industrial complex with an area of 8.4 ha for operation of about twenty companies. In the assumption of heat demand, four companies only were taken up as the object of the discussion, who utilize heat supply from steam as process heat source for their factories. The total heat demand quantity and heat demand pattern used for the discussion were assumed by hearing and actual record submitted from each company. Optimal systems were discussed on heat supply systems utilizing steam produced by steel mills, with the discussion made on waste heat recovered steam in processes and steam extracted from thermal electric power plants in the steel mills. As a result of the discussion, heat supply utilizing the steel mill steam was found capable of being provided with much lower price level as the estimated unit price than general direct steam supply, leading to a judgement that the system has business feasibility.

    For contributing to the formulation of technology development programs, an analysis is conducted based on the concept of value web into which the economic spread effect is incorporated. As information technology plays an important role in the fields of automobiles and chemical materials, there are various fields the research and development efforts exerted in which are common to many others. As to what additional values are created when such separately developed technologies cross each other, a discussion is conducted using techniques of industry-oriented analyses. Findings obtained are mentioned below. When the numbers of essays relative to the respective industries are compared, it is found that 63% of the total number of biotechnological essays fall on agriculture, the drug industry, and the food industry. On the other hand, when it comes to the produce, related industries larger in marketing scale is more strongly influenced by the spread effect.

    This report surveys potential impacts of ASEAN (Association of South East Asian Nations) on inter-ASEAN affairs and its external relations when ASEAN will enlarge its members to include all nations in South East Asia, and thus fully represent the region. For this purpose, the survey was conducted on Vietnam, Myanmar, Laos and Cambodia, which joined in 1995, from the viewpoint of their economic and political system, and their relations with other member countries. The nature of ASEAN has gradually transformed, in which all the countries in the region have increased and internal economic issues have been tackled. It has an aim to stimulate inter-ASEAN trade and induce foreign direct investment into ASEAN as a whole by reducing import duties on intra-ASEAN trade. Underlying in these, new development is a concern about growing economic and military power of China. ASEAN solidarity will work an leverage against China should change toward worse, and ASEAN will function as a regional stabilization factor. ASEAN is needed for the stability of both in economic and political order in East Asia. Japan has to further promote its cooperation with ASEAN to help its solidarity as an association. 24 refs., 21 figs., 25 tabs.

    New energy technologies have had the subsidy institutions established in association with advancement of the technologies, and such introduction promoting measures developed as the introduction assistance and advisory project. To promote this development more effectively, it is necessary that different data related to new energies are put into order comprehensively and systematically to be retained as the basic data. Therefore, this paper collects and puts into order the latest published data on cogeneration from among other new energy technology areas, with main regard to system listing, specific introduction examples, subsidy institutions, and how other countries are working on the technologies. Hydroelectric power generation uses up head energy of water by installing power plants along a river from higher location to lower location. Similarly the cogeneration is a kind of multi-stage energy utilization (cascade utilization) system that uses up energy serially from as high oil and natural gas combustion temperature as 1,500 degrees C or higher down to temperature levels used for hot water supply and air conditioning as low as 45 to 50 degrees C. It generates electric power by using a thermal engine, and utilizes waste heat effectively. (NEDO)

    For diffusion of waste power generation, cost reduction is important. As the profitability evaluation technique for conventional waste power systems, a simple recovery year method, total waste treatment cost method, generation cost method, and evaluation method by accumulated balance sheet are presented along with their principles. For the generation cost method, trial calculation results are presented based on documents reported. From methods for the study in Institute of Applied Energy, some estimation methods of construction cost are presented, and generation cost and profitability evaluation were studied by parametric accumulation method. The profitability was calculated for RDF power systems, and it was clarified that although as a whole this system is more efficient than a simple refuse incineration system, the balance sheet of local governments is dependent on a responsibility range for the facility. In a combined type (super refuse power generation), generally municipalities bear a combustor and boiler, while a prefecture bears generation facilities. Because of large scale generation, the profitability is dependent on a selling price of electricity. 37 refs., 36 figs., 24 tabs.

    A survey was conducted on the energy situation in Thailand, Indonesia, Malaysia, the Philippines and India, and a possibility of making an international joint research. Thailand has sharply increased investments from Europe and the U.S. since 1985, and has been making a rapid industrialization. As to the energy policy, it is important to secure the stable supply and stabilize the price. Indonesia has been rapidly increasing energy consumption in accordance with the recent economic growth, and is fear of becoming a net oil importing country in the near future. They are taking a policy for securing as much domestic oil and gas as possible. Malaysia has been keeping a high growth of over 8% per year for the past 8 years and rapidly increased energy demand. It is expected that they will maintain a high level of the development of energy resources. In the Philippines, the industrial energy is mostly coal, but electricity expected in future is from the oil-fueled power generation. The stable import of oil is a problem. 45 figs., 51 tabs.

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

    Studies are made of optimum materials and methods for manufacturing low-carbon fuels for reduction in greenhouse gas emissions. When their thermal dynamic limits and the technological maturity are considered, it is inferred that no extensive improvement will be achieved by merely improving on the efficiency of the existing fuels. The use of various high-efficiency driving power sources utterly different in mechanism from the conventional ones, such as those for fuel cell-powered automobiles, and the promotion of the use of low-carbon fuels such as methanol and methane for all kinds of driving power sources including those for the said fuel cell-powered automobiles, will become necessary. The use will also be necessary of recyclable materials. The biomass resources, in particular, since they absorb CO2 gas in their growing process by virtue of photosynthesis, may be said to be free of CO2 gas emissions. They have their own problems, however, which involve the economy of energy consumed for their production, harvesting, transportation, and conversion into fuels. It is therefore required that their whole life cycle be studied before their greenhouse gas reduction effect may be correctly assessed. The quantities of resources available for the production of automotive low-carbon fuels, manufacturing technologies, etc., are first of all put in order for easy perusal. An effective way is assessed for the whole including the life cycle. (NEDO)

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

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)

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

    Various kinds of biological fixation processes of CO2 were evaluated from the various viewpoints. Afforestation of tropical and temperate areas, greening of desert, biomass energy production in these areas by energy plantation, coastal mangrove plantation, fertilization with nitrogen and phosphate to outer ocean and coastal, upwelling zone fertilization with iron, and coral reef expansion combined with OTEC (ocean thermal energy conversion) were comparatively investigated as the selected measures. As a result, the cost of CO2 fixation by cultivation of sea weed and plankton was much higher than that of afforestation. The iron fertilization method which was considered to be one of the high CO2 reduction potentials might be economical. However, its effect could not be quantitatively evaluated. The afforestation of tropical and temperate areas seemed to be most feasible in a short term from the viewpoints of economy and environment. It was suggested that the establishment of a systematic water management technology could make greening and afforestation of desert. 76 refs., 27 figs., 28 tabs.

    Research was made on joint implementation (JI) for preventing global climate changes in China. Since such the stove and furnace consume a large amount of energy, their improvement and energy saving are important for integrated iron plants. Maanshan iron plant was selected for the research. All the furnaces were manually operated without combustion control systems, and oxygen meters for exhaust gas frequently troubled. As measures for the stoves, operation at a proper air fuel ratio, improvement of over heat storage combustion, and dust cleaning for waste heat recovery gas heaters were proposed. For the furnaces, a proper oxygen content at the end of furnaces (reduction of invasion air) was proposed to improve exhaust gas loss up to that in Japan. For this target, reinforced instrument management and standardized combustion control are essential. JI of software improvement for operation and management can reduce annual greenhouse effect gas emission to 45,900t and 6,300t in carbon equivalent for the stove and furnace, respectively. CO2 reduction is also estimated to be 1,173,000t and 205,000t in China of 107,570,000t in raw steel production, respectively. 28 figs., 32 tabs.

    The paper grasped the state of coal utilization by coal consumption field, the state of coal physical flow in Vietnam, etc., surveyed/studied a possibility of introducing the environment friendly type coal utilization system, and assessed the possibility. As to energy resources, the north is abundant in hydroelectric and coal (mainly anthracite) resources, and the south in oil and natural gas resources. Coal production in fiscal 1997 is planned to be 10 million tons. Coal preparation technique presently available is only grain size sieving. Accordingly, it is necessary to study for heightening efficiency of facilities and modernizing facilities in accordance with the introduction of the environment friendly type coal utilization technology. During the study, it is possible to propose improvement on coal processing technology (coal preparation technology). Assessment and study are made especially of the coal selection system, fine coal recovery system and waste water treatment system. For the plan on new coal-fired power plants (300MWtimes4), there is left much necessity of proposing studying models considered of the anthracite combustion technology and environmental improvement and of assessing/studying them. 60 figs., 117 tabs.

    A feasibility study of a model project was conducted on energy conservation and introduction of technology against pollution for Fe-alloy electric furnaces in China. The total production of Fe-alloy was 4.32 million tons in 1995, which recorded the maximum production. Out of which ferro-Cr occupied 9.5%. Production of high carbon ferro-Cr in 2000 is estimated to be 600,000 tons. China`s electric furnaces for ferro-Cr using carbon as heat source do not have covers and gas recovery systems. The gas from furnaces is burnt and wasted, which results in air pollution. To cover the furnaces, grading of powder materials is indispensable for improving the ventilation in furnaces. In Japan, sintering and pelletizing methods were developed. In China, the covering and gas recovery are performed for furnaces using expensive massive ores. In most cases, they are not performed. For three works at Jilin, Lioyang and Jinzhou surveyed in this project, recovered gas can be effectively utilized, which would provide energy saving and environment improving effects. They have enough site areas and workshops in the sites. Construction works can be conducted by China themselves. 6 figs., 32 tabs.

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

    To avoid economic and technological risks upon initial introduction of distributed new power source technology, methods for reduction in the initial investment burden under the lease system and methods for risk reduction under the insurance system are discussed, and each is evaluated for their applicability to the new technology. Methods for popularizing and enlightening the technology are also discussed using the result of a 'survey for promoting the introduction of new energies' conducted into local autonomies assuming the role of diffusing the new technology into the residential and commercial sectors. Through the review of the current status of initial investment burden reduction methods mainly under the lease system and through some case studies, the applicability of such methods to the new technology is discussed. Similar studies are also made by investigating the current status of risk reduction methods and by conducting case studies, these centering on various kinds of machinery insurance. Questionnaires are sent to local autonomies, who play an important part in the initial introduction into and popularization in the residential and commercial sectors, to learn their consciousness of energy problems and of distributed new power source technology introduction. The result is used to review how popularization and enlightenment activities should be conducted. (NEDO)

    The hardware which supports IT is composed of information processing (MPUs and memories), information communication (input/output and communication) and information storage as the three basic elements. This project studies development of the basic technologies for realization of tera-bit (1TB/in{sup 2}) class information storage, in order to cope with drastically increased volume of information as a result of progress of the IT revolution. An HDD (hard disk device) will be the sole device which can correspond to required large-capacity, high-speed storage. However, realization of the recording density for 1TB class storage needs materials and controlling technologies at the atomic and molecular levels, because all of the basic technologies therefor, e.g., those for recording medium, head device and positioning mechanisms, are characterized by nm-order technologies. In other words, it is important to promote the research and development activities for the technologies for three-dimensionally configuring/controlling the atoms, processing magnetic materials at the nm level, and superhigh-speed devices. The concerted efforts by the industrial, government and academic sectors are required for quickly realizing the technological breakthroughs, which need advanced processes based on new principles and development facilities.

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

    This paper describes development of structural materials for municipal refuse incinerators, in particular, high- temperature corrosion-resistant ceramics for inner walls. Unlike boiler tubes of which inner walls are cooled by water or water vapor, refractory for inner walls is subjected to high-temperature flame over 1000degC, corrosive gases such as HCl and SO2. and low-melting point corrosive dust such as chloride, sulfate and oxide under strong corrosive environment. Experiment was made on 14 kinds of ceramics including commercially available oxide system, non-oxide system and refractory system ceramics. Except graphite system ones, every ceramics, in particular, Al2O3, ZrO2, B4C-doped SiC and CVD-SiO showed superior properties. Commercially available ceramics, in particular, non-oxide system ones are very expensive. Since inner wall materials for refuse incinerators are heat-/corrosion-resistant consumption articles, it is suggested that improvement of reasonable oxide system ceramics or conventional SiC system ones is better. 73 refs., 89 figs., 39 tabs.

    Described herein are the FY 1988 results of development of corrosion-resistant ceramic materials for garbage incinerators. Residue released when porcelain stocks are collected is selected as the inexpensive stock for SiO{sub 2}-Al{sub 2}O{sub 3}-based refractory materials. It is incorporated with carbon black and reduced at 1,200 to 1,500 degrees C in a nitrogen atmosphere. Synthesis of the target Si-Al-C-N-O-based compound succeeds in the presence of a solid catalyst, but it is a fine powder, and hence that of the massive compound fails. The commercial ceramic materials and new refractory materials, made on a trial basis, are evaluated for their resistance to corrosion using fry ashes collected from a commercial incinerator. These ashes are higher in melting point, more viscous, holding a larger quantity of attached slag and more corrosive than synthetic ashes. These materials are corroded acceleratedly as temperature increases to 1,200 degrees C or higher, more noted with the ceramic materials than with the refractory materials. Oxidation and melting characteristics of the molten slag affect corrosion of some materials. Use of the graphite-based material shall be limited to a section below the slag surface, where graphite is oxidized to a smaller extent. The MgO-based material is promising. The Al{sub 2}O{sub 3}-Cr{sub 2}O{sub 3}-based material is more promising than any other material developed in this study. Their bending strength before and after the corrosion test is measured at normal temperature to 1,700 degrees C, to investigate their deterioration by high temperature and corrosion. (NEDO)

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

    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.

    The paper grasps the present situation of economy and industry in Kazakhstan and studies a policy for developing the industrial machine manufacturing industry of the country. Since the independence in 1992, the country is now at the great turning point in politics, economy, society and industry. The country is forced to convert from the industrial structure of one local area where much of its own discretion had not been given under the economy system of power centralization to the industrial structure which meets the international economic market system as an independent country. Making good use of agricultural and industrial property in the former U.S.S.R., the country needs to export energy resource like oil, natural gas and coal, and abundant ore resource like iron and non-ferrous metal, which were added with values. As the technical base for it, fostering and strengthening of the industrial machine manufacturing industry is important. At present, the situation is that because of the economic sluggishness, the country cannot manufacture domestically even basic mechanical parts and simply-manufactured parts which are required by the domestic energy industry, machine manufacturing industry, and other industries. The technical program to be proposed by Japan is planned to be worked out later based on the basic research made in fiscal 1993. 6 figs., 14 tabs.

    A comprehensive analysis was conducted into the results of a survey on the state of existence of geothermal energy resources in the Musadake region, Shibetsu-gun, Hokkaido. The region was volcanically active in the period from the Neogene period into the quaternary, with some volcanos still active even today. The geological structure on the whole is characterized by the Musadake/Mt. Shitabanupuri fault which is the major structure running NNE-SSW and having a folding structure. It is inferred that Musadake is the heat source responsible for the underground temperature distribution in this region. The maximum temperature of 274 degrees C is recorded at borehole N11-MD-3 in the northeastern part of Musadake, and the temperature falls rapidly as the distance from the borehole increases. Ejection of geothermal fluids is observed at boreholes N11-MD-3 and N11-MD-4. It is inferred that the deep-seated geothermal water is of the neutral Cl type with Cl concentration estimated at approximately 12,000 mg/liter. Steam composition is characterized by a gas concentration level that is as high as 3-4 vol.%. The gas is composedly mainly of CO2 and contains some hydrocarbons. Fluids in this region are classified into water mixing into deep-seated geothermal water and groundwater originating in meteoric water. (NEDO)

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

    A synthetic analysis was made of the results of the fiscal 1992 survey on geothermal resource existing in the Mannenyama area. The area surveyed is located at the central-west part of Oita prefecture, belonging to an administrative division of Kusu-machi and Kokonoe-cho, Kusu-county, Oita pref. The area surveyed was approximately 280 km{sup 2}. As signs of existence of geothermal energy, there are seen hot springs and alteration zones there. In the Takigami district neighboring the south-east part of the area, construction of a geothermal power plant is being planned. From a synthetic consideration of various investigations, the region round the Inomuta sedimentation zone is considered to be a district satisfying conditions for existence of geothermal resource and a promising geothermal district, where Takigami, Otake, Hachoubaru and Okuni are widely included. In the area surveyed this time, the area around Noya-Mizuwaketouge seems to be the most potential for geothermal resource, judging from the alteration status, abnormal mercury concentration, fault state structure and spread of the low resistivity zone. Also in the south and the north-east of the area, geothermal activities can be estimated. 99 refs., 194 figs., 52 tabs.

    With an objective to save energy and reduce greenhouse gas emission, a project has been discussed to introduce a gas turbine combined cycle power generation system for effective waste heat utilization and a pellet coating facility into the direct reduction steel making plant of Ahwaz Steel Complex in the Islamic Republic of Iran. The project will have a waste heat boiler installed at the outlet of the MIDREX plant waste heat recovery device to link it with a gas turbine combined cycle power plant to structure a 42-MW power generation system. In addition, productivity enhancement was attempted by applying the raw material pellets with coating to raise the reduction gas blow-in temperature. The energy saving effect expected from this project would be saving of 63,140 tons of crude oil equivalent annually, and the greenhouse effect gas reducing effect would reduce 173,790 t-CO2 annually. Although the investment will require about 3.16 billion yen, the cost reduction amount in association with power generation is small because of the power purchase unit cost being as very low as 1.9 yen/kWh, making the investment recovery period 10.2 years. Therefore, the project will not be realizable economically. (NEDO)

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

    In Japan with its rapidly aging society, fundamental technologies are required for the development of artificial nerves substituting for or supporting damaged ones, and ultimately constituting artificial neurons based on the knowledge of the brain functions at the molecular and cellular levels. This study defines the fundamental technologies which would be required for the development in the area, and further, evaluates the potential of the technologies to develop the novel industry. The brain function is closely related to the activity in neuronal circuits. In order to repair injured nerves and to develop the advanced technologies of electronics for helping impaired neuronal functions, the most important and urgent is to understand how to work the neuronal circuit system in the brain. Based on these viewpoints, new methodological approaches would make it possible to relieve neural impairment in the sensory input system and the motor system by the use of electronic circuits. They also would improve rehabilitation after injury, and treat neurodegenerative diseases such as Parkinson`s disease. These advances surely create the new types of industry seeds in near future. 77 refs., 29 figs., 2 tabs.

    Trends were surveyed for development of an ultra low loss power element. Performance improvement has been progressed on power semiconductor elements by using Si as the raw material, but loss reduction has come close to the physical limit. SiC is expected of possibility to go beyond this limit. SiC is so very excellent that its band gap is two to three times greater, insulation breakdown electric field is 7.5 times higher, temperature to become a true semiconductor is three to four times higher than those of Si. The wide gap can reduce high temperature leaking current in p-n junctions, and the increased authenticity temperature can increase the upper limit for operation temperature. The insulation breakdown strength being higher by one digit can reduce the drift layer thickness, and is expected to dramatically reduce the loss. The problem is that high quality crystals have not been obtained to date. One of the promising application fields is electric vehicle. The device currently using the power element in the largest scale is used in frequency converting stations to link the 50-Hz power network in the eastern part of Japan to the 60-Hz network in the western part of Japan. Surveys were carried out on the Sakuma frequency converting station and the New Shinano substation. (NEDO)

    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)

    Research was made on improvement of the wettability and boiling heat transfer characteristics of a photocatalyst wall. Measurement experiment of the wettability was made for anatase type titan oxide-coated Al, SUS and Pb plates, rutil type titan oxide-flame coated SUS plate, raw plate, and oxide-plasma coated titan plate. In the ground experiment, the contact angles of distilled water and oil on specimen surfaces were measured. In the microgravity experiment, falling droplet images were recorded by using the facility of Japan Microgravity Center (JAMIC). For obtaining the effect of radioactive emission, UV irradiation, {gamma} ray and neutron beam irradiation by nuclear reactor, and {gamma} ray irradiation by Co-60 were carried out. As the experiment result, the rutil type titan oxide-flame coated SUS plate, nonconductor-coated titan plate, and zircaloy plate showed large improvement of the wettability by {gamma} ray irradiation with Co-60. It was also confirmed that in particular, titan shows the large effect of radioactive emission, and the wettability deteriorates rapidly after {gamma} ray irradiation. (NEDO)

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

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

    The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

    The activities implemented jointly (AIJ) is expected as global measures to reduce greenhouse gas (such as CO2) emission. In this report, the possibility of AIJ projects in developing countries was researched. The United Nations Framework Convention on Climate Change was signed by 155 countries in 1992. This convention parties approved AIJ projects for measures against global warming. The 1st Conference of the Parties (COPI) held in 1995 approved the pilot phase of AIJ by voluntary workers jointly with developing countries until the end of this century. The trend, level and future plan of energy conservation technologies were researched and analyzed for steelmaking, cement and electric power supply industries in both the Philippine and Thailand. The possibility of AIJ projects was studied by selecting several Japanese energy conservation technologies transferable to both countries. The same research was also carried out for forest as carbon absorption source. 5 refs., 23 figs., 58 tabs.

    A research is conducted into China's current problems of energy-related environments, and studies are made for the assessment of its potentials for greenhouse gas reduction, such as CO2 from coal, and for the prevention of environmental pollution in urban areas. By the survey of the current states of the supply and demand of energy and heat in China, and in Beijin, it is found that fuel conversion, which means the disuse of coal in this case, is necessary for a success in SO2 measures in the heat supply department. Since the rate of concentrated heat supply undertaken by heat supply businesses is low, it is inferred that potentials for CO2 reduction are quite high in this department. Concerning technological problems about conversion from coal to natural gas and heat supply, deliberation is made on a scenario covering how to approach the energy demand model, combustion in the natural gas boiler, and the home heating fuel. In discussing air pollution in China, the difficulty known as transboundary air pollution is taken up. It is concluded that conversion from coal to natural gas or coal disuse will serve effectively the purposes of energy saving, SO2 reduction, and CO2 reduction. (NEDO)

    The paper collected and arranged data on new energy technology. As to the waste power generation, in terms of general waste, 161 places have power generation facilities, 657,000 kW in output, as of the end of FY 1996. Out of them, 100 facilities (scale of output: 555,000 kW) are selling power. In terms of industrial waste, 53 places (209,000 kW) have power generation facilities. The output will be 2 million kW in FY 2000. In relation to the solar energy utilization, the number of solar systems introduced in FY 1996 is 25,000, that of water heating appliances produced in FY 1996 is 170,000. Geothermal power of 494,000 kW and 37,000 kW was introduced for electric power industry use and private use, respectively. Clean energy vehicles have not been so much spread, but the hybrid car was put on sale in 1997. Concerning the coal liquefaction, the R and D were made at a pilot plant of NEDOL process, and operation started in 1997. As to the coal gasification, investigational study and element study on the demonstration plant are being conducted in FY 1997 and 1998, making use of the research results obtained from the existing pilot plant of coal gasification combined power generation

    As a part of the FY 1998 geothermal development promotion survey, the results were summed up of the environmental effect survey conducted at the Akinomiya area of Ogachi-gun, Akita prefecture. In the survey, the drilling of N9-AY-4 exploration well and short-term injection tests of N8-AY-2/N9-AY-3 were carried out in the area. The survey was made aiming at grasping the effects on hot spring/ground water level/spring water in the area. The methods used for survey were surveys of hot spring variation, ground water level variation, precipitation, rivers, all spring sources, and analyses of hot spring water/spring water in the Akinomiya area. As a result of the survey, in hot spring/ground water level/spring water, no variations were recognized which were caused by the drilling of N9-AY-3/N9-AY-4/N9-AY-5 exploration wells and short-term injection tests of N8-AY-2/N9-AY-3 exploration wells. Moreover, since few changes of spring water quality were seen also in the result of the survey of all spring sources, it was judged that the drilling and short-term injection tests of the exploration wells described above have no effects on the hot spring, ground water level and spring water in the Akinomiya area.

    Surveys and discussions were given on business feasibility of a wide area RDF power generation system in the Kishu and Kumano living area. The discussions dealt with as wide area as transcending prefectural borders and including the southern parts of Mie and Nara Prefectures with the city of Shingu as the central part. Wastes generation amount is estimated to be about 70,000 tons at the present as wastes that can be turned into RDF, and to be decreased to 67,000 tons in 2018. The manufactured RDF has calorific power of 3500 to 4500 kcal/kg, two to three times greater than that of wastes. The RDF manufacturing facilities installed in cities, towns and villages have capacity of 30 to 50 tons a day, with that in the city of Shingu being the largest at about 78 tons a day. Transportation can be implemented most efficiently when road transportation is used. The RDF power generation system will consist of a fluid bed furnace, a plasma type ash melting furnace, and a bag filter plus activated carbon absorbing tower. The RDF manufacturing cost will be 27,900 yen per ton of wastes in the case of the city of Shingu. In terms of business profitability, the RDF power generation must find sources to pay 21,400 yen per ton of RDF even if the power sale revenue is considered. (NEDO)

    Current electricity markets in Europe and the USA are drastically changing due to the introduction of competition principle and the reconsideration of business systems. Are also changing the activities and their forms of DSM (demand side management) for load leveling which has been conventionally conducted by electricity companies for the efficient operation of facilities. Task IV and Task VI aim at developing new mechanisms to promote DSM in the changing electricity markets as well as disseminating and communicating information on the new mechanism. Japan participates in Sub-task IV/6 and 7 and Task VI. Activities for developing new mechanisms are divided into Phase 1 and Phase 2. The Phase 1 includes review of existing mechanisms and preliminary development and evaluation of new mechanisms. The Phase 2 includes the detailed development of new mechanisms and evaluation criteria, communication and information about mechanisms, and identification of the public policy implications which would follow a decision by the responsible authorities to implement each of various DSM mechanisms. The time frame of Phase 1 is between February 1996 and March 1997, and that of Phase 2 is between January 1997 and December 1999. 2 figs., 4 tabs.

    The field research of oil conservation was conducted in developing countries, in particular, Vietnam where a steep increase in oil consumption is anticipated in the future. Energy conservation is the most effective direct measures to control combustion of fossil fuels, and an important issue to be promoted by all countries in the world to prevent global warming and reserve energy resources. In fiscal 1994, main industries in the northern part of Vietnam were researched. In fiscal 1995, the report meeting of plant survey results in the northern part and the technical seminar of energy-saving in industrial field were held, and plants around Ho Chi Minh City in the southern part of Vietnam were researched. Although Vietnam has recently acquired membership in ASEAN and is undergoing dramatic economic growth, has many problems in environmental measures. Japan has top-ranking results on energy-saving in industrial field, and the transfer of such superior technologies and techniques will greatly contribute to resource and global warming problems as well as pollution control measures in Vietnam. 13 refs., 25 figs., 26 tabs.

    This report summarizes the research result on development of new coal exploration technology. For a high-precision and high-resolution reflective seismic exploration system, R and D was made on the exploration technology of several meter in resolution for medium-depth (800m) coal deposits under a lake of 2m deep. As a result, the high-frequency and high-power source (150-200Hz in dominant frequency, 700-800m in penetrability) and the high-frequency and high sensitivity receiver (10-1000Hz in frequency band, 35V/PA in sensitivity) were developed successfully, and the positioning system was improved. The final evaluation of these elementary technologies was carried out through demonstration tests, resulting in satisfactory results. For a high-efficiency trial drilling system, the in-bore trouble prevention system for measurement, processing and analysis of drilling data (drilling length, drilling rate, revolution, bit load, torque) and drilling mud data (charge water pressure, charge/discharge water, density, pH, viscosity) was constructed. The outlook for low-cost measurement and a safety during drilling was thus obtained. (NEDO)

    A fundamental investigation was carried out on coal mine development in Palakan Area, East Kalimantan, the Republic of Indonesia. Based on the existing information available from geological investigations having been performed to date, including trial drilling, the present investigation carried out mapping surveys for new access roads to each trial drilling location and coal bed investigations on the existing open-cut mining sites. The trial drilling investigations were conducted by using grids with about 500 meter interval to identify existence status of coal beds and coal quality. Seven drillings to depths of 170 to 230 m resulted in a total drilling length of 1350 meters. Trial drilling samples were collected from all beds in major coal beds, and analyzed in Japan according to JIS standard. Overall geological analysis including coal quantity calculation by coal beds, open-cut sites and underground mining sites was executed from available geological sketches, geological histograms, coal bed histograms and other existing items of information. Evaluation was given on potentiality of the investigated areas for coal development based on the above analytical results. In addition, infrastructure related investigations were also performed. 29 refs., 114 figs., 37 tabs.

    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.

    NEDO is positively implementing the training programs, in view of importance of training experts on (energy-saving and environmental conservation technologies), by inviting administrators and engineers from developing countries to educate them with Japan's pollution preventive techniques, administration procedures, energy-saving measures, and so on. In FY 1998, NEDO commissioned the International Center for Environment Technology Transfer to train administrators and engineers from Indonesia, the Philippines, Vietnam and Myanmar. This paper describes the proposals, based on the collected answers of the trainees to the questionnaires. The trainees were interested in all themes. About 40% of the trainees considered that the training period was short. Some trainees hoped the training course was held in summer. Difference in industrialization is reflected in difference in recognition and urgency of the environmental problems. Training was conducted by English and Vietnamese, but could be done without translators of Vietnamese. Preparation for the invitation needs a lot of works, and the course should be explained more thoroughly beforehand. It is regrettable that one trainee from Indonesia was late for the course. (NEDO)

    An investigational study was conducted on the project for energy conservation and reduction in greenhouse effect gas emission at the existing district heating plant in Tbilisi City, Georgia. In the project, the following are conducted for the district heating plants in the Didi-Digomi section and Saburtalo section: renewal/higher efficiency of boiler equipment, adoption of cogeneration using gas turbine, improvement of hot water pipeline and improvement of equipment at heat users. As a result of the study, one plan for cogeneration of 2 units x 6MW class in each section was good in terms of economical efficiency and expenses vs. effects, and the other plan for cogeneration of 17 units (8 units and 9 units) x 6MW class was good in terms of the generated output and regional needs. The amount of energy conservation to be made by the former plan totaled 22,678 toe/y in both sections. The amount of greenhouse effect gas reduction is 70,170 t-CO2/y. The internal earning rate is 1.707% in the Didi-Digomi section and 2.249% in the Saburtalo section. The project profit is lower than the initial investment cost, and therefore, it is necessary to consider the profit from the CO2 emission right. (NEDO)

    Discussions have been given on the improvement and modification project intended of saving energies and reducing greenhouse gas emission in the Potoshani district heating and heat supplying facilities in Romania. Thirty years have elapsed since the building of the Potoshani district heating and heat supplying facilities, whereas noticeable energy loss has occurred due to aged deterioration, such as thermal efficiency decrease, performance decrease, and hot water leakage due to piping corrosion. The present project is intended to improve the heat production and power generation facility efficiencies, and reduce the heat loss in heat transportation and distribution to less than 5%. The improvements will be implemented by replacing and rehabilitating the existing boilers, replacing the turbine generators, and replacing the transportation and distribution pipelines and heat exchangers. As a result of the discussions, the present project is estimated to result in annual fuel conservation of 35,820 tons of crude oil equivalent, and annual reduction of the greenhouse gas emission of 110,835 t-CO2. The total amount of the initial investment for the project would be 11.369 billion yen, and the payback period would be 12 years. The project will produce profit of 31.358 billion yen in 20 years, thus the project is financially feasible. (NEDO)

    The monetary crisis in Thailand with the baht drop in July 1997 as a beginning rapidly worsened the Thai economy. With it, the number of automobiles sold sharply declined, and automobile manufacturers were also heavily damaged as seen in the temporary discontinued production, etc. Under such economic situation, a discussion was made on execution of the project with the Thai Automotive Industry Association (TAIA), a partner at the Thai side. As a result, agreement was made on the positioning of the project, role sharing, and selection of measures against heavy traffic as follows: Japan Automobile Manufacturers Association (JAMA) conducts a feasibility study, proposal of a construction plan and confirmation of effects, and bears the costs. TAIA bears the execution and cost of construction (Due to the worsened Thai economy, JAMA paid almost all the construction expenses). In the light of the economic situation in Thailand, `improvement of the signal control system` was selected as an execution candidate, which has the highest cost effect among the measures against heavy traffic. In the future, the application, registration and execution are done for joint activities for the project. 49 figs., 59 tabs.

    Full Text Available Abstract Background The underlying goal of synthetic biology is to make the process of engineering biological systems easier. Recent work has focused on defining and developing standard biological parts. The technical standard that has gained the most traction in the synthetic biology community is the BioBrick standard for physical composition of genetic parts. Parts that conform to the BioBrick assembly standard are BioBrick standard biological parts. To date, over 2,000 BioBrick parts have been contributed to, and are available from, the Registry of Standard Biological Parts. Results Here we extended the same advantages of BioBrick standard biological parts to the plasmid-based vectors that are used to provide and propagate BioBrick parts. We developed a process for engineering BioBrick vectors from BioBrick parts. We designed a new set of BioBrick parts that encode many useful vector functions. We combined the new parts to make a BioBrick base vector that facilitates BioBrick vector construction. We demonstrated the utility of the process by constructing seven new BioBrick vectors. We also successfully used the resulting vectors to assemble and propagate other BioBrick standard biological parts. Conclusion We extended the principles of part reuse and standardization to BioBrick vectors. As a result, myriad new BioBrick vectors can be readily produced from all existing and newly designed BioBrick parts. We invite the synthetic biology community to (1 use the process to make and share new BioBrick vectors; (2 expand the current collection of BioBrick vector parts; and (3 characterize and improve the available collection of BioBrick vector parts.

Superior mechanisms function efficiently in organisms for perception, transmission and processing of information, and transport and conversion of substances. These functions are caused by harmonization between organic molecules, or organic molecule and metal or inorganic substance. HMM is a key substance to realize these functions similar to those of organisms artificially. It is the purpose of this research to develop HMMs, reform production process by innovating separation and conversion technologies, and finally realize molecular chemical plants. This research also develops high-efficient devices to contribute to the information society, and progresses the industry of bio-functional materials such as high-sensitive bio-sensor.

    The use of diamond for advanced applications has been the dream of mankind for centuries. Until recently this dream has been realized only in the use of diamond for gemstones and abrasive applications where tons of diamonds are used on an annual basis. Diamond is the material system of choice for many applications, but its use has historically been limited due to the small size, high cost, and inconsistent (and typically poor) quality of available diamond materials until recently. The recent development of high quality, single crystal diamond crystal growth via the Chemical Vapor Deposition (CVD) process has allowed physcists and increasingly scientists in the life science area to think beyond these limitations and envision how diamond may be used in advanced applications ranging from quantum computing, to power generation and molecular imaging, and eventually even diamond nano-bots. Because of diamond's unique properties as a bio-compatible material, better understanding of diamond's quantum effects and a convergence of mass production, semiconductor-like fabrication process, diamond now promises a unique and powerful key to the realization of the bio-electronic devices being envisioned for the new era of medical science. The combination of robust in-the-body diamond based sensors, coupled with smart bio-functionalized diamond devices may lead to diamond being the platform of choice for bio-electronics. This generation of diamond based bio-electronic devices would contribute substantially to ushering in a paradigm shift for medical science, leading to vastly improved patient diagnosis, decrease of drug development costs and risks, and improved effectiveness of drug delivery and gene therapy programs through better timed and more customized solutions.

Therefore, bio-ethanol is not the right intermediate (short term) technology, and it is not the right long term technology either......Throughout the world, nations are seeking ways to decrease CO2 emissions and to reduce their dependency on fossil fuels, especially oil and gas deriving from so-called politically unstable regions. The efforts comprise the energy sector (heat and electricity) as well as the transport sector......, that biomass substitutes gas in the heat & power sector and gas substitute oil in the transport sector. By taking this path, we overall achieve almost twice as high a CO2 reduction and save almost twice as much oil, as if we want to substitute the oil via car engines through conversion to ethanol. We must...

  16. Production of bio-energies

    International Nuclear Information System (INIS)

    After having indicated the various possible origins of biomass, this paper considers the issue of bio-energies, i.e., energies produced with biomass related to forest or agriculture production. Some indicators are defined (share of renewable energies, share of biomass in the energy production and consumption, number of production units). Stake holders are identified. Then, major and emerging trends are identified and discussed. The major trends are: development and diversification of renewable energies, development of bio-fuels with the support of incentive policies, prevalence of the wood-energy sector on the whole renewable energies, increase of surfaces dedicated to bio-fuels since the end of the 1990's, a French biogas sector which is late with respect to other countries. The emerging trends are: the important role of oil price in the development of bio-fuels, a necessary public support for the development of biogas, mobilization of research and development of competitiveness poles for bio-industries. Some prospective issues are also discussed in terms of uncertainties (soil availabilities, environmental performance of bio-fuels, available biomass resource, need of a technological advance, and evolution of energy needs on a medium term, tax and public policy). Three hypotheses of bio-energy evolutions are discussed

  17. Bio diesel production from algae

    International Nuclear Information System (INIS)

    Algae appear to be an emerging source of biomass for bio diesel that has the potential to completely displace fossil fuel. Two thirds of earth's surface is covered with water, thus alga e would truly be renewable option of great potential for global energy needs. This study discusses specific and comparative bio diesel quantitative potential of Cladophora sp., also highlighting its biomass (after oil extraction), pH and sediments (glycerine, water and pigments) quantitative properties. Comparison of Cladophora sp., with Oedogonium sp., and Spirogyra sp., (Hossain et al., 2008) shows that Cladophora sp., produce higher quantity of bio diesel than Spirogyra sp., whereas biomass and sediments were higher than the both algal specimens in comparison to the results obtained by earlier workers. No prominent difference in pH of bio diesel was found. In Pakistan this is a first step towards bio diesel production from algae. Results indicate that Cladophora sp., provide a reasonable quantity of bio diesel, its greater biomass after oil extraction and sediments make it a better option for bio diesel production than the comparing species.

    In relation to the basic study of the standardization for hydrogen energy technology and ISO/TC197, the results of the fiscal 1997 survey were summarized. From fiscal 1994 through 1996, in the wide-range field related to hydrogen energy technology, the survey of the present situation of the related standards/laws was made and the needs/subjects of standardization to be studied in the future were extracted. At the present stage, however, it is still early to enter into the stage of discussing the standardization. Therefore, in this fiscal year, only in the field of the storage/transportation/handling of liquid hydrogen, standards/laws abroad and in Japan were comparatively investigated for the basic study toward the standardization. Further, concerning ISO/TC197, studies were proceeded with of the liquid hydrogen land vehicle fueling system interface/fuel tanks/transportation containers/hydrogen fuel product specifications/airport hydrogen fueling facilities. Some are at the stage of drafting the international standard. Three drafts for the new standard were added such as gaseous hydrogen/hydrogen blend vehicular fuel systems, gaseous hydrogen fuel tanks, and basic requirements for safety of hydrogen systems. The standardization is indispensable to introducing the developed technology to the commercialization. 9 refs., 5 figs., 13 tabs.

    Nature still outperforms the most powerful computers in routine functions involving perception, sensing and actuation like vision, audition, and motion control, and is, most strikingly, orders of magnitude more energy-efficient than its artificial competitors. The reasons for the superior performance of biological systems are subject to diverse investigations, but it is clear that the form of hardware and the style of computation in nervous systems are fundamentally different from what is used in artificial synchronous information processing systems. Very generally speaking, biological neural systems rely on a large number of relatively simple, slow and unreliable processing elements and obtain performance and robustness from a massively parallel principle of operation and a high level of redundancy where the failure of single elements usually does not induce any observable system performance degradation. In the late 1980`s, Carver Mead demonstrated that silicon VLSI technology can be employed in implementing ``neuromorphic'' circuits that mimic neural functions and fabricating building blocks that work like their biological role models. Neuromorphic systems, as the biological systems they model, are adaptive, fault-tolerant and scalable, and process information using energy-efficient, asynchronous, event-driven methods. In this paper, some basics of neuromorphic electronic engineering and its impact on recent developments in optical sensing and artificial vision are presented. It is demonstrated that bio-inspired vision systems have the potential to outperform conventional, frame-based vision acquisition and processing systems in many application fields and to establish new benchmarks in terms of redundancy suppression/data compression, dynamic range, temporal resolution and power efficiency to realize advanced functionality like 3D vision, object tracking, motor control, visual feedback loops, etc. in real-time.

    Full Text Available AbstractBio-nanopatterning of surfaces is a very active interdisciplinary field of research at the interface between biotechnology and nanotechnology. Precise patterning of biomolecules on surfaces with nanometre resolution has great potential in many medical and biological applications ranging from molecular diagnostics to advanced platforms for fundamental studies of molecular and cell biology. Bio-nanopatterning technology has advanced at a rapid pace in the last few years with a variety of patterning methodologies being developed for immobilising biomolecules such as DNA, peptides, proteins and viruses at the nanoscale on a broad range of substrates. In this review, the status of research and development are described, with particular focus on the recent advances on the use of nanolithographic techniques as tools for biomolecule immobilisation at the nanoscale. Present strengths and weaknesses, as well future challenges on the different nanolithographic bio-nanopatterning approaches are discussed.

  10. Bio politics - The bio-environment - bio-culture of the Danube

    International Nuclear Information System (INIS)

    The bio-environment has been the single most important correlation in human history and can successfully promote international co-operational co-operation and understanding. With the construction of a network for collaboration, the 'Danube Countries' can come together in celebration of their culture and heritage. As the Danube flows from the Black Forest to the Black Sea, it carries messages of peace, hope and co-operation. Applying these messages to every endeavour can improve our quality of life and lead to a brighter future. Since its inception in 1985, the Bio politics International Organization (B.I.O.) has been labouring to raise awareness of the urgent need to instate a new system of norms and principles, compatible with sound environmental management and with the most important task of ensuring global literacy on environmental issues. Along with critically re-assessing the concept of profit, the goal is to adopt a system of bio centric values, where respect for the bio-environment will govern our every action and thought

    BioC is a simple XML format for text, annotations and relations, and was developed to achieve interoperability for biomedical text processing. Following the success of BioC in BioCreative IV, the BioCreative V BioC track addressed a collaborative task to build an assistant system for BioGRID curation. In this paper, we describe the framework of the collaborative BioC task and discuss our findings based on the user survey. This track consisted of eight subtasks including gene/protein/organism named entity recognition, protein-protein/genetic interaction passage identification and annotation visualization. Using BioC as their data-sharing and communication medium, nine teams, world-wide, participated and contributed either new methods or improvements of existing tools to address different subtasks of the BioC track. Results from different teams were shared in BioC and made available to other teams as they addressed different subtasks of the track. In the end, all submitted runs were merged using a machine learning classifier to produce an optimized output. The biocurator assistant system was evaluated by four BioGRID curators in terms of practical usability. The curators' feedback was overall positive and highlighted the user-friendly design and the convenient gene/protein curation tool based on text mining.Database URL: http://www.biocreative.org/tasks/biocreative-v/track-1-bioc/.

  15. Bio-mimetic Flow Control

    Choi, Haecheon

    2009-11-01

    Bio-mimetic engineering or bio-mimetics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology (from Wikipedia). The concept itself is old, but successful developments have been made recently, especially in the research field of flow control. The objective of flow control based on the bio-mimetic approach is to develop novel concepts for reducing drag, increasing lift and enhancing aerodynamic performance. For skin friction reduction, a few ideas have been suggested such as the riblet from shark, compliant surface from dolphin, microbubble injection and multiple front-body curvature from penguin, and V-shaped protrusion from sailfish. For form drag reduction, several new attempts have been also made recently. Examples include the V-shaped spanwise grooves from saguaro cactus, overall shape of box fish, longitudinal grooves on scallop shell, bill of swordfish, hooked comb on owl wing, trailing-edge protrusion on dragonfly wing, and fillet. For the enhancement of aerodynamic performance, focuses have been made on the birds, fish and insects: e.g., double layered feather of landing bird, leading-edge serration of humpback-whale flipper, pectoral fin of flying fish, long tail on swallowtail-butterfly wing, wing flapping motion of dragonfly, and alula in birds. Living animals adapt their bodies to better performance in multi purposes, but engineering requires single purpose in most cases. Therefore, bio-mimetic approaches often produce excellent results more than expected. However, they are sometimes based on people's wrong understanding of nature and produce unwanted results. Successes and failures from bio-mimetic approaches in flow control will be discussed in the presentation.

    Concerning the above, it is discussed whether such a system is feasible in Japan. A zinc/air cell system requires some special plants for zinc regeneration, etc. It is necessary to build a zinc refining plant and to install dozens of electrode replacing facilities in an area dozens of kilometers in diameter with the plant at the center. For such a system to be functional, there have to be several tens of thousands of automobile users in a limited area. In Japan, so large a number will not be found anywhere even if the appeal is directed to those in the postal service and electric utilities. There will be no economic success in Japan, different from in Germany. As for the economic comparison between a zinc/air cell system and natural gas system, the two will be equivalent to each other as far as the use of the quick filling stations for the natural gas automobiles remains as it is. When the number in consideration is so large as several tens of thousands, however, the natural gas system will turn out to be economically superior to the zinc/air cell system. 19 figs., 29 tabs.

    The paper described the fiscal 1997 result of the fracture hydraulic exploration method as the variation exploration method of geothermal reservoirs. By elucidating hydraulic characteristics of the fracture system forming reservoir, technologies are established which are effective for the reservoir evaluation in early stages of development, maintenance of stable power after operational start-up, and extraction of peripheral reservoirs. As for the pressure transient test method, a test supporting system was basically designed to obtain high accuracy hydraulic parameters. As to the tiltmeter fracture monitoring method, a simulation was made for distribution of active fractures and evaluation of hydraulic constants without drilling wells. In relation to the two-phase flow measuring method, for stable steam production, the use of the orifice plate, the existing flow measuring method, etc. was forecast as a simple measuring method of the two-phase state of reservoir. Concerning the hydrophone VSP method, a feasibility study was made of the practical VSP for high temperature which can analyze hydraulic characteristics and geological structures around the well at the same time which the existing methods were unable to grasp, and brought the results. Moreover, to make high accuracy reservoir modeling possible, Doppler borehole televiewer was made in each reservoir. 80 refs., 147 figs., 22 tabs.

    Investigations were given on a device technology that can obtain energy saving and environment preserving effects in electric furnace iron making using reduced iron as a raw material. The effects can be obtained by continuously charging into an electric furnace the reduced iron supplied from an iron ore reducing plant while the iron is kept hot. The investigations were carried by sending survey groups to India and Mexico who are producing reduced iron, and Egypt and Malaysia who possess iron reducing technologies, and by analyzing the actual conditions of reduced iron manufacturing equipment and electric furnace facilities. In addition, retrieval, collection and analysis were performed on technical data and information on reduced iron available inside and outside the country. As a result, a proposal was made to select India as a site to execute the demonstration study on the hot reduced iron insertion technology. The reasons for the selection are: India has a large number of steel mills that have iron reducing facilities and electric furnaces; the country is geographically convenient for Japanese research institutes to implement the demonstration study; the country`s DRI production is the largest in the south-eastern Asia; and electric power cost is high. 92 refs., 49 figs., 30 tabs.

    An investigational study was conducted of possibilities of energy conservation and greenhouse effect gas emission reduction in the cement production process of Double Horse Cement Co., Mianyang City, Sichuan Province, China. Double Horse Cement adopts the wet type long kiln production system and has a production ability of approximately 1.5 million t/y. In the project, as to three production lines out of the six production lines, improvement was planned to be made of the technologies on the following: mixing of raw materials, grinding of raw materials, NSP, clinker cooler, clinker pre-grinder, high-efficiency separator, waste heat use power generation, etc. As a result of the study, it was found that the energy conservation amount obtained was 54,646 toe/y. And, the amount of greenhouse effect gas reduction was 169,086 t-CO2/y. The total fund required for this project was approximately 5.553 billion yen and the internal earning rate was 7.36% after tax. When the project is carried out, expenses vs. effects are 9.8 toe/million yen in energy conservation amount and 30.4 t-CO2/million yen in greenhouse effect gas reduction. (NEDO)

    This paper makes an analysis on the characteristics of R and D concerning Australia, one of the core nations in the cooperation, on the basis of the idea that 'establishment of new comparative superiority through cooperation' can be realized by joint work among Japan, Australia and Asian nations. In Australia, it was found that R and D was often promoted through a new idea obtained by recruiting heterogeneous persons and communicating mutually internally. It was also found that in Australia an affinity exists to such persons of different nature. Accordingly, Australia was presumably quite suitable for the place to bring up the persons of developing nations. On the basis of these analytical results, proposal was made to promote three programs; namely, preparation of a data base for R and D organizations and the staff, commencement of a partnership program, and opening of a needs searching conference.

    This paper reports the result in fiscal 1995 of the study on PLD (pulse laser deposition) thin film formation process having been made since 1993. In fiscal 1995, the effect of irradiation of excimer laser and YGA(SHG) on ablation of aggregates of N2, CH4, Ar, Kr and Xe, and the effect of time-delayed irradiation of YGA(SHG) and KrF excimer laser on ablation of N2 aggregate were studied aiming at exciting ablation by cryogenic aggregate alone. Experimental results by a newly developed multi-laser excitation experiment equipment are as follows. Ablation was not caused by KrF excimer laser irradiation, while caused by YGA(SHG) irradiation. Ablation was caused by 1mm thick N2 or CH4 aggregate alone. Kr target was the most promising among rare gas solid targets expected as seed of ablation occurrence. Multi-irradiation showed a different ablation behavior as compared with single YGA(SHG) irradiation, and in some cases, multi-irradiation not increased scattering of particles. Time-delayed multi- irradiation (YGA(SHG) excitation after excimer excitation) was effective. 23 figs., 4 tabs.

    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.

    Nitrogen monoxide is a strong greenhouse effect gas having warming up index per molecule 300 times greater than that of CO2, and is designated as the object of reduction in the Kyoto Conference. The present preceding research discusses necessity of performing research and development works related to reducing the emission of nitrogen monoxide, and if it is necessary, places the final objective on proposition of what researches should be planned. Fiscal 1997 being the first fiscal year of the preceding research has surveyed emission amount from different emission sources, and enumerated the research and development assignments. Fiscal 1998 falling under the final fiscal year summarizes the emission amount including the future trends, surveys the feasibility of the promising technological measures through experiments, and proposed finally a research and development plan desired of implementation in the future. The proposal contains a research plan placing development of nitrogen monoxide decomposing catalysts and automobile catalysts as the main objectives. Among the domestic nitrogen monoxide generating sources, about 2/3 is the man-made generation sources, hence catalysts, if developed, may be applied to such facilities as combustion furnaces. (NEDO)

    In order to reduce environmental load, such as suppression of dioxin generation in Kagoshima Prefecture having a large number of small cities, towns and villages, discussions were given on business feasibility of introducing a high-efficiency industrial wastes power generation system intended for the whole Kagoshima prefectural area. The discussions performed investigations on quantity of wastes generation by districts and kinds and the present treatment conditions, system designs, and optimization of business operation systems. Loads given to the environment in association with the system installation were also investigated (SOx, NOx and CO2 emission, and water quality contamination). The system incinerates and treats RDF, waste plastics and combustible wastes in a gasification melting furnace, and amount of dioxin in the waste gas and ash is reduced to below the regulation values. Quantity of heat obtained from the combustion is turned into high-temperature and high-pressure steam, which is utilized for power generation. As a result of the discussions on business profitability, the industrial wastes power generation system intended for the whole prefectural area was found sufficiently realizable if installed by the public organization and operated by private business organization. However, such mechanism as PFI is thought difficult in the range anticipated at the present time. (NEDO)

    To evaluate geothermal reservoirs in the initial stage of development and keep stable output in service operation, measurement of self-potential and resistivity changes due to production and reinjection of geothermal fluid has been made. This paper describes the result in fiscal 1997. To study the placing method and stability of electrodes for continuous self-potential monitoring network in fiscal 1998, continuous monitoring of potential differences started in an experimental field. The placing condition and electrode will be selected by July. By surveying self-potentials after the beginning of operation of Oogiri geothermal power plant, a distribution range of negative and positive potential anomalies was clarified. To predict the resistivity change, long-term change in salinity concentration in a reservoir was estimated by a hydrothermal flow concept model. The resistivity change caused by reservoir variation due to plant operation was also predicted to study its detection by MT method on the ground. The salinity concentration change due to reinjection, and resistivity change due to a two-phase region in the top of a reservoir were considered. 17 refs., 56 figs., 19 tabs.

    To evaluate geothermal reservoirs in the initial stage of development and keep stable output in service operation, the application of MEMS is under development. This paper describes the result in fiscal 1997. Installation of 3-component velocity type seismometers in bore holes is desirable for permanent monitoring sites. Their arrangement should be determined by detection ability simulation. Their locations at various elevations are effective to improve the accuracy of hypocenter determination. Digital seismic data at the permanent sites are transmitted to a center through cables, while temporary data are recorded on site. For poor MEPAS, a Windows program of basic functions was developed. 3-D seismic velocity analysis and array monitoring system were also studied. A P-wave velocity of rocks decreased by 25% by formed two-phase region, and increased by 10% by decrease in reservoir temperature from 200 to 100degC. The velocity can be detected by change in travel time of direct waves due to considerable variation in reservoir environment. VSP technique using a vibrator or air gun as artificial hypocenter is effective for MEMS. 67 refs., 64 figs., 19 tabs.

    A feasibility study is conducted of the above-named system in Malaysia, to be linked to COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) clean development mechanism (CDM). The dual mode bus system (DMBS) is a combination of advantages of the rail running stock such as monorails and the road running stock in that the buses when running on dedicated roads are automatedly formed into a linear formation and travel at a specified economical speed. When running on ordinary roads, the formation is broken into individual buses, and they spread in the town where they travel in a planar pattern. The economical speed and reduction in air drag thanks to the linear formation saves fuel and reduces CO2 emissions. The complementary relationship to be formed with the existing public transportation systems will also function positively. Studies are conducted on condition that two routes be laid in the Kuala Lumpur urban area and one in the new city Putra Jaya. All the three routes exhibit a high economic internal rate of return, but their financial internal rate of return indicates that probabilities are low that they will pay as private businesses. They will need financial supports such as subsidies. Contribution to CO2 reduction may be slight when attention is paid only to the partial changeover from the existing bus system to DMBS but larger contribution will be found in crossover from private cars to DMBS which is higher in quality of service.

    Pursuant to the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol, studies are conducted on a district cogeneration station for Radom City, Poland. Using the annual load pattern of heat supply, cogeneration will be built only for the amount that covers utilization factors not lower than a specified level, and the shortage in winter when the load is heavy due to demand for heat will be dealt with by the existing hot water boilers. Daily change in load is to be covered by a new, additional boiler which will bear 20% of the whole output. The system is a natural gas fired turbine cogenerator, and hot water is supplied by a waste heat recovery boiler. Cogeneration will cover 80% of the annual heat supply. As for heat supply capability, it is set at 72MWt with the additional boiler taken into account, and 35MWe is to be generated. Heat efficiency will increase to be higher than 80%, coal consumption will decrease, and 28,117 tons/year in terms of oil will be saved with the increase in natural gas consumption subtracted. CO2 reduction will also be as large as 206,000 tons/year, decreasing air pollutants. Provided that 4.336-billion yen for facilities are financed by Japan's environmental yen loan, Poland's National Fund, and Radom City's own fund, IRR (internal rate of return) on investment will be fairly good at 10% in 30 years of operation. Investment will be recovered in nine years and there is no problem in cash flow. (NEDO)

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    Investigations and discussions have been given on energy saving possibilities at two medium-sized heat and power supplying plants in the city of Dailian in China. The project will improve the operation methods of the heat and power plants so that the energy cost can be minimized, and attempt to improve the boiler heat efficiency and save the energy by means of heat recovery and utilization. The draft modification plan for energy conservation has planned operation optimization for energy conservation, control of boiler operation under variable pressure, modification of the external boiler heat converter, use of inverters for the large capacity motors for boilers, and recovery of heat from the boiler blow-down water. In the analysis, models were structured from the operation data, and the effects of applying the energy saving measures were derived from simulation. As a result, the energy saving effect was found to be about 13,000 tons at the Chunhai plant and about 7,000 tons at the Pulandian plant annually (converted to oil). The reduction in greenhouse gas emission was found to be about 40,000 tons at the Chunhai plant and about 20,000 tons at the Pulandian plant annually. The number of years for investment payback is about 4.1 years at the Chunhai plant, and about 4.9 years at the Pulandian plant, wherein good profitability can be estimated. (NEDO)

    Full Text Available The BioAmbients calculus is a process algebra suitable for representing compartmentalization, molecular localization and movements between compartments. In this paper we enrich this calculus with a static type system classifying each ambient with group types specifying the kind of compartments in which the ambient can stay. The type system ensures that, in a well-typed process, ambients cannot be nested in a way that violates the type hierarchy. Exploiting the information given by the group types, we also extend the operational semantics of BioAmbients with rules signalling errors that may derive from undesired ambients' moves (i.e. merging incompatible tissues. Thus, the signal of errors can help the modeller to detect and locate unwanted situations that may arise in a biological system, and give practical hints on how to avoid the undesired behaviour.

    The BioRefine - new biomass products programme is approaching its final active year 2012. The programme contains several significant industrial research and development projects that aim to demonstrate large scale biorefineries. At the same time, a number of projects are led by SMEs focusing on smaller localised solutions. The programme is co-operating closely with Forestcluster Ltd, one of the Strategic Centres for Science, Technology and Innovation in Finland, which is owned by major forest-related companies and institutes. Forestcluster has launched a second phase of its Future Biorefinery (FuBio) programme, which aims to create a new world-leading-competence platform in the field of biorefinery and to develop new value chains in which wood is refined into materials and chemicals. Together the two programmes are a central part of the Finnish biorefining entity. One of the main goals of the BioRefine programme has been to bring together multidisciplinary research and development competences and different business areas for creating sustainable and commercially viable biorefinery concepts. With the increasing pressure on low-carbon processes and on the efficient and sustainable use of raw materials, the need for a multidisciplinary approach has become evident. Bioeconomy aims to bring these different competence and business areas into close co-operation for creating new solutions based on non-fossil raw materials. In the future, the holistic and multidisciplinary approach to utilising biomass resources efficiently and in an environmentally and economically sustainable way will be increasingly emphasized

    International Nuclear Information System (INIS)

    This study examined bio-oil and bio-char fuel produced from Spirulina Sp. by slow pyrolysis. A thermogravimetric analyser (TGA) was used to investigate the pyrolytic characteristics and essential components of algae. It was found that the temperature for the maximum degradation, 322 °C, is lower than that of other biomass. With our fixed-bed reactor, 125 g of dried Spirulina Sp. algae was fed under a nitrogen atmosphere until the temperature reached a set temperature between 450 and 600 °C. It was found that the suitable temperature to obtain bio-char and bio-oil were at approximately 500 and 550 °C respectively. The bio-oil components were identified by a gas chromatography/mass spectrometry (GC–MS). The saturated functional carbon of the bio-oil was in a range of heavy naphtha, kerosene and diesel oil. The energy consumption ratio (ECR) of bio-oil and bio-char was calculated, and the net energy output was positive. The ECR had an average value of 0.49. -- Highlights: •Bio-oil and bio-char fuel produced from Spirulina Sp. by slow pyrolysis. •Suitable temperature to obtained bio-oil and bio-char were at about 550 and 500 °C. •Saturated functional carbon of bio-oil was heavy naphtha, kerosene, diesel oil. •ECR had an average value of 0.49

  11. Bio-fuel production potential in Romania

    International Nuclear Information System (INIS)

    The paper is based on the ESTO Study: Techno- Economic Feasibility of Large-Scale Production of Bio-Fuels in EU-Candidate Countries. Bio-fuel production has not been taken into account significantly until now in Romania, being limited to small- scale productions of ethanol, used mostly for various industrial purposes. However the climatic conditions and the quality of the soil are very suitable in the country for development of the main crops (wheat, sugar-beet, sunflower and rape-seed) used in bio-ethanol and bio-diesel production. The paper intended to consider a pertinent discussion of the present situation in Romania's agriculture stressing on the following essential items in the estimation of bio-fuels production potential: availability of feed-stock for bio-fuel production; actual productions of bio-fuels; fuel consumption; cost assessment; SWOT approach; expected trends. Our analysis was based on specific agricultural data for the period 1996-2000. An important ethanol potential (due to wheat, sugar-beet and maize cultures), as well as bio-diesel one (due to sun-flower and rape-seed) were predicted for the period 2005-2010 which could be exploited with the support of an important financial and technological effort, mainly from EU countries

    Single-molecule, real-time sequencing developed by Pacific BioSciences offers longer read lengths than the second-generation sequencing (SGS) technologies, making it well-suited for unsolved problems in genome, transcriptome, and epigenetics research. The highly-contiguous de novo assemblies using PacBio sequencing can close gaps in current reference assemblies and characterize structural variation (SV) in personal genomes. With longer reads, we can sequence through extended repetitive regions and detect mutations, many of which are associated with dis-eases. Moreover, PacBio transcriptome sequencing is advantageous for the identification of gene isoforms and facilitates reliable discoveries of novel genes and novel isoforms of annotated genes, due to its ability to sequence full-length transcripts or fragments with significant lengths. Addition-ally, PacBio’s sequencing technique provides information that is useful for the direct detection of base modifications, such as methylation. In addition to using PacBio sequencing alone, many hybrid sequencing strategies have been developed to make use of more accurate short reads in conjunction with PacBio long reads. In general, hybrid sequencing strategies are more affordable and scalable especially for small-size laboratories than using PacBio Sequencing alone. The advent of PacBio sequencing has made available much information that could not be obtained via SGS alone.

    2011-02-01

    Full Text Available Abstract Background Phyloinformatic analyses involve large amounts of data and metadata of complex structure. Collecting, processing, analyzing, visualizing and summarizing these data and metadata should be done in steps that can be automated and reproduced. This requires flexible, modular toolkits that can represent, manipulate and persist phylogenetic data and metadata as objects with programmable interfaces. Results This paper presents Bio::Phylo, a Perl5 toolkit for phyloinformatic analysis. It implements classes and methods that are compatible with the well-known BioPerl toolkit, but is independent from it (making it easy to install and features a richer API and a data model that is better able to manage the complex relationships between different fundamental data and metadata objects in phylogenetics. It supports commonly used file formats for phylogenetic data including the novel NeXML standard, which allows rich annotations of phylogenetic data to be stored and shared. Bio::Phylo can interact with BioPerl, thereby giving access to the file formats that BioPerl supports. Many methods for data simulation, transformation and manipulation, the analysis of tree shape, and tree visualization are provided. Conclusions Bio::Phylo is composed of 59 richly documented Perl5 modules. It has been deployed successfully on a variety of computer architectures (including various Linux distributions, Mac OS X versions, Windows, Cygwin and UNIX-like systems. It is available as open source (GPL software from http://search.cpan.org/dist/Bio-Phylo

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

    In this article we discuss a novel approach to Bio-Radar, contactless measurement of bio-signals, called Cognitive Bio-Radar. This new approach implements the Bio-Radar in a Software Defined Radio (SDR) platform in order to obtain awareness of the environment where it operates. Due to this, the Cognitive Bio-Radar can adapt to its surroundings in order to have an intelligent usage of the radio frequency spectrum to improve its performance. In order to study the feasibility of such implementation, a SDR based Bio-Radar testbench was developed and evaluated. The prototype is shown to be able to acquire the heartbeat activity and the respiratory effort. The acquired data is compared with the acquisitions from a Biopac research data acquisition system, showing coherent results for both heartbeat and breathing rate.

  1. SCR at bio fuel combustion

    International Nuclear Information System (INIS)

    In this project the cause for and the extent of catalyst deactivation has been investigated when using 100 % wood as fuel. The trend of deactivation has been studied as a function of the flue gas temperature, the type of catalyst and the type of combustion technique used. The field tests have been performed in the CFB boiler in Norrkoeping, firing forest residues, and in the boiler in Jordbro, firing pulverized wood (PC). Samples of four different commercial catalyst types have been exposed to flue gas in a test rig connected to the convection section of the boiler. The samples have been analysed at even time intervals. The results after 2 100 hours show a large difference in deactivation trend between the two plants; when using a conventional honeycomb catalyst 80 % of the original activity remains in the CFB boiler but only 20 % remains in the PC boiler. The deactivation in the CFB boiler is about 3 - 4 times faster than what is expected for a conservative design for a coal fired boiler. The results show that the general deactivation trend is similar for the plate and the honeycomb catalyst types. With a catalyst optimised for bio fuels the deactivation rate was about 2/3 compared with a conventional catalyst. At an operating temperature of 315 deg C the deactivation was not as rapid as at 370 deg C. The amount of easily dissolved potassium increases on the surface of the catalyst, especially in the PC boiler, and this is probably the reason for the deactivation. The total amount of potassium in the flue gas is about 5 times higher in the CFB boiler compared with the PC boiler. This indicates that only a certain form of potassium attacks the catalyst and that the total alkali content of the fuel is not a good indicator of the deactivation tendency. The potassium on the catalyst dissolves easily in both water and sulphuric acid. A wash of deactivated catalyst samples with water resulted in higher activity than for the fresh samples if the washing was supplemented

    International Nuclear Information System (INIS)

    The substitution of natural gas by a renewable equivalent is an interesting option to reduce the use of fossil fuels and the accompanying greenhouse gas emissions, as well as from the point of view of security of supply. The renewable alternative for natural gas is green natural gas, i.e. gaseous energy carriers produced from biomass comprising both biogas and Synthetic Natural Gas (SNG). Via this route can be benefited from all the advantages of natural gas, like the existing dense infrastructure, trade and supply network, and natural gas applications. In this presentation attention is paid to the differences between first generation biogas and second generation bioSNG; the market for bioSNG: grid injection vs. transportation fuel; latest update on the lab- and pilot-scale bioSNG development at ECN; and an overview is given of ongoing bioSNG activities worldwide

  6. Negated bio-events: analysis and identification

    Full Text Available Abstract Background Negation occurs frequently in scientific literature, especially in biomedical literature. It has previously been reported that around 13% of sentences found in biomedical research articles contain negation. Historically, the main motivation for identifying negated events has been to ensure their exclusion from lists of extracted interactions. However, recently, there has been a growing interest in negative results, which has resulted in negation detection being identified as a key challenge in biomedical relation extraction. In this article, we focus on the problem of identifying negated bio-events, given gold standard event annotations. Results We have conducted a detailed analysis of three open access bio-event corpora containing negation information (i.e., GENIA Event, BioInfer and BioNLP’09 ST, and have identified the main types of negated bio-events. We have analysed the key aspects of a machine learning solution to the problem of detecting negated events, including selection of negation cues, feature engineering and the choice of learning algorithm. Combining the best solutions for each aspect of the problem, we propose a novel framework for the identification of negated bio-events. We have evaluated our system on each of the three open access corpora mentioned above. The performance of the system significantly surpasses the best results previously reported on the BioNLP’09 ST corpus, and achieves even better results on the GENIA Event and BioInfer corpora, both of which contain more varied and complex events. Conclusions Recently, in the field of biomedical text mining, the development and enhancement of event-based systems has received significant interest. The ability to identify negated events is a key performance element for these systems. We have conducted the first detailed study on the analysis and identification of negated bio-events. Our proposed framework can be integrated with state-of-the-art event

    This paper is a generalized report in relation with the mine waste water treatment technology utilizing biotechnology, from among the promotion projects for research cooperation with China. Ferric iron (Fe{sup 3+}), which precipitates at low pH, is produced by utilizing bacteria which derives energy from oxidizing ferrous iron (Fe{sup 2+}) in the waste water, and the iron is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Joint researches and developments have been carried out on selection of optimal kinds of bacteria, cultivation of bacteria oxidizing iron at high efficiency, optimal removal system of heavy metals in mine waste water, and recovery of useful resources. Japanese engineers were sent to sites in China, Chinese researchers were received in Japan, and pilot plants were operated and studied. For the purpose of proliferating and enlightening the result of the project, a seminar was held in Beijing in February 1998. In order for the achievements derived up to fiscal 1998 to be used in diverse fields, fiscal 1999 will carry out follow-ups, including assistance, for the voluntary researches performed by China. The follow-ups will also include confirmation on the state of testing the iron oxidizing bacteria technology, technical guidance, and analyses and discussions on the data. (NEDO)

    A material that manifests biological function is being developed by synthesizing peptide containing non-natural amino acids and by combining with a material such as a silicon substrate. Activities were conducted in the two areas of (1) development of innovative technologies for producing functional molecules (structure/function design of peptide) and (2) development of materialization technologies of functional molecules. In (1), for the purpose of developing a method of simulating the function of a low molecular weight compound by peptides, using as the lead compound, Cbz-Phe-Phe-His-NH{sub 2}, which is the minimum active manifestation unit having a macropharge migration stimulating activity, various conversions were tried with the aim of improving the activity, revealing that the activity changed greatly by the conversions. Dehydroalanine-containing tripeptide derivatives, which were synthesized on the basis of the result of a molecular design by computer, showed 1,000 times more activity than the lead compound. In (2), experiments for forming a crystal thin film of peptides were conducted using a pattern forming fixation process of peptides by a photo-reactive cross-linking reagent and by means of an organic crystal growth multiple beam apparatus.

    As a rule, oil- and gas-processing equipment and pipelines are attacked by different microorganisms. Their vital ability determines processes of bio-deterioration and bio-corrosion that lead often to technological accidents and severe environmental contamination. Bio-films presenting a complex association of different microorganisms and their metabolites are responsible for most of damages. In this context, to study the role bio-films may play in processes of bio-damages and in efficacy of protective measures is important. We have developed method of culturing bio-films on the surface of metal coupons by using a natural microbial association isolated from oil-processing sites. Simple and informative methods of determining microbiological parameters of bio-films required to study bio-corrosion processes are also developed. In addition, a method of electron microscopic analysis of bio-films and pitting corrosion is offered. Using these methods, we conducted model experiments to determine the dynamics of corrosion processes depending on qualitative and quantitative composition of bio-films, aeration conditions and duration of the experiment. A harmful effect of soil bacteria and micro-mycetes on different pipeline coatings was also investigated. Experiments were conducted within 3-6 months and revealed degrading action of microorganisms. This was confirmed by axial tension testing of coatings. All these approaches will be used for further development of measures to protect gas- and oil-processing equipment and pipelines against bio-corrosion and bio-damages (first of all biocides).

  20. A new bio-active glass ceramic

    International Nuclear Information System (INIS)

    Since 1960 fine ceramics such as alumina have been used side by side with metallic materials for bone and joint replacement. They have high mechanical strength and are free from corrosion problem faced by metals. However they don't bond to the natural living bone and hence are called bio-inactive. This was followed by the development of bio-active glasses and glass-ceramics which bond to the natural bone but have low mechanical strength. In the present work a new bio-active glass-ceramic, based on CaO-SiO/sub 2/-P/sub 2/O/sub 3/-MgO composition, has been developed which has mechanical strength compared to that of a bio-inactive glass ceramic and also bonds strongly to the natural bone. X-ray diffraction analysis reveals wollastanite and apatite phases in the glass ceramic. A new bio-active cement has also been developed which can be used to join broken pieces of bone or by itself at a filler. (author)

  1. Bio-oil production from cotton stalk

    International Nuclear Information System (INIS)

    Cotton stalk was fast pyrolyzed at temperatures between 480 deg. C and 530 deg. C in a fluidized bed, and the main product of bio-oil is obtained. The experimental result shows that the highest bio-oil yield of 55 wt% was obtained at 510 deg. C for cotton stalk. The chemical composition of the bio-oil acquired was analyzed by GC-MS, and its heat value, stability, miscibility and corrosion characteristics were determined. These results showed that the bio-oil obtained can be directly used as a fuel oil for combustion in a boiler or a furnace without any upgrading. Alternatively, the fuel can be refined to be used by vehicles. Furthermore, the energy performance of the pyrolysis process was analyzed. In the pyrolysis system used in our experiment, some improvements to former pyrolysis systems are done. Two screw feeders were used to prevent jamming the feeding system, and the condenser is equipped with some nozzles and a heat exchanger to cool quickly the cleaned hot gas into bio-oil

    As demand for soil improvement continues to increase, new, sustainable, and innocuous methods are needed to alter the mechanical properties of soils. Recent research has demonstrated the potential of bio-mediated soil improvement for geotechnical applications (DeJong et al. 2006, Whiffin et al. 2007). Upscaling the bio-mediated treatment process for in situ implementation presents a number of challenges to be addressed, including soil and pore fluid interactions, bioaugmentation versus biostimulation of microbial communities, controlled distribution of mediated calcite precipitation, and permanence of the cementation. Current studies are utilizing large-scale laboratory experiments, non-destructive geophysical measurements, and modeling, to develop an optimized and predictable bio-mediated treatment method.

    As wireless bio-medical long term monitoring moves towards personal monitoring it demands very high input impedance systems capable to extend the reading of bio-signal during the daily activities offering a kind of "stress free", convenient connection, with no need for skin preparation. In particular we highlight the development and broad applications of our own circuits for wearable bio-potential sensor systems enabled by the use of an FET based amplifier circuit with sufficiently high impedance to allow the use of passive dry electrodes which overcome the significant barrier of gel based contacts. In this paper we present the ability of dry electrodes in long term monitoring of ECG, EEG and fetal ECG.

    A major difficulty in monitoring and control of bio-processes is the lack of reliable and simple sensors for following the evolution of the main state variables and parameters such as biomass, substrate, product, growth rate, etc... In this article, an adaptive estimation algorithm is proposed to recover the state and parameters in bio-processes. This estimator utilizes the physical process model and the reference model approach. Experimentations concerning estimation of biomass and product concentrations and specific growth rate, during batch, fed-batch and continuous fermentation processes are presented. The results show the performance of this adaptive estimation approach. (authors) 12 refs.

  12. Comparative techno-economic analysis of biohydrogen production via bio-oil gasification and bio-oil reforming

    International Nuclear Information System (INIS)

    This paper evaluates the economic feasibility of biohydrogen production via two bio-oil processing pathways: bio-oil gasification and bio-oil reforming. Both pathways employ fast pyrolysis to produce bio-oil from biomass stock. The two pathways are modeled using Aspen Plus® for a 2000 t d−1 facility. Equipment sizing and cost calculations are based on Aspen Economic Evaluation® software. Biohydrogen production capacity at the facility is 147 t d−1 for the bio-oil gasification pathway and 160 t d−1 for the bio-oil reforming pathway. The biomass-to-fuel energy efficiencies are 47% and 84% for the bio-oil gasification and bio-oil reforming pathways, respectively. Total capital investment (TCI) is 435 million dollars for the bio-oil gasification pathway and is 333 million dollars for the bio-oil reforming pathway. Internal rates of return (IRR) are 8.4% and 18.6% for facilities employing the bio-oil gasification and bio-oil reforming pathways, respectively. Sensitivity analysis demonstrates that biohydrogen price, biohydrogen yield, fixed capital investment (FCI), bio-oil yield, and biomass cost have the greatest impacts on facility IRR. Monte-Carlo analysis shows that bio-oil reforming is more economically attractive than bio-oil gasification for biohydrogen production. -- Highlights: ► Biohydrogen production via bio-oil reforming has higher energy efficiency compared to gasification. ► Hydrogen price, fixed capital cost, and feedstock cost most strongly affect IRR. ► Lower risk investment is biohydrogen production via bio-oil reforming

    The interest in using Jatropha curcas L. (JCL) as a feedstock for the production of bio-diesel is rapidly growing. The properties of the crop and its oil have persuaded investors, policy makers and clean development mechanism (CDM) project developers to consider JCL as a substitute for fossil fuels to reduce greenhouse gas emissions. However, JCL is still a wild plant of which basic agronomic properties are not thoroughly understood and the environmental effects have not been investigated yet. Gray literature reports are very optimistic on simultaneous wasteland reclamation capability and oil yields, further fueling the Jatropha bio-diesel hype. In this paper, we give an overview of the currently available information on the different process steps of the production process of bio-diesel from JCL, being cultivation and production of seeds, extraction of the oil, conversion to and the use of the bio-diesel and the by-products. Based on this collection of data and information the best available practice, the shortcomings and the potential environmental risks and benefits are discussed for each production step. The review concludes with a call for general precaution and for science to be applied. (author)

    2013-11-01

    The drive to design micro-scale medical devices which can be reliably and uniformly mass produced has prompted many researchers to adapt processing technologies from the semiconductor industry. By operating at a much smaller length scale, the resulting biologically-oriented microelectromechanical systems (BioMEMS) provide many opportunities for improved drug delivery: Low-dose vaccinations and painless transdermal drug delivery are possible through precisely engineered microneedles which pierce the skin's barrier layer without reaching the nerves. Low-power, low-volume BioMEMS pumps and reservoirs can be implanted where conventional pumping systems cannot. Drug formulations with geometrically complex, extremely uniform micro- and nano-particles are formed through micromolding or with microfluidic devices. This review describes these BioMEMS technologies and discusses their current state of implementation. As these technologies continue to develop and capitalize on their simpler integration with other MEMS-based systems such as computer controls and telemetry, BioMEMS' impact on the field of drug delivery will continue to increase.

    T.SUBRAMANI

    2014-06-01

    Full Text Available The potential of biodegradable polymers and more particularly that of polymers obtained from renewable resources such as the polysaccharides (e.g., starch have long been recognized. However, these biodegradable polymers have been largely used in some applications (e.g., food industry and have not found extensive applications in the packaging industries to replace conventional plastic materials, although they could be an interesting way to overcome the limitation of the petrochemical resources in the future. The fossil fuel and gas could be partially replaced by greener agricultural sources, which should participate in the reduction of CO2 emissions. Bio-based and biodegradable plastics can form the basis for environmentally preferable, sustainable alternative to current materials based exclusively on petroleum feed stocks. These bio-based materials offer value in the sustainability/life-cycle equation by being a part of the biological carbon cycle, especially as it relates to carbon-based polymeric materials such as plastics, water soluble polymers and other carbon based products like lubricants, biodiesel, and detergents. Identification and quantification of bio based content uses radioactive C-14 signature. Biopolymers are generally capable of being utilized by living matter (biodegraded, and so can be disposed in safe and ecologically sound ways through disposal processes (waste management like composting, soil application, and biological wastewater treatment. Single use, short-life, disposable products can be engineered to be bio-based and biodegradable.

    International Nuclear Information System (INIS)

    Energy demand is increasing day by day because of the rapid developments in the population, industrialization and urbanisation. Since, fossil fuels will be at the verge of getting extinct, researches are mostly focused on the renewable sources, such as biomass, in recent years. This paper provides an environmentally friendly process to convert waste biomass samples to bio-oil and bio-char by pyrolysis. For this purpose, pyrolysis characteristics of pomegranate peels under inert atmosphere were studied by using both TGA to analysis decomposition behaviour and a batch reactor to investigate product yields and properties. The properties of bio-oil and bio-char were investigated by different analytical techniques such as GC-MS, FT-IR, SEM, He pycnometry and elemental analysis. As a consequence, it is possible to obtain bio-oil, which has similar properties like petroleum hydrocarbons, and to obtain bio-char, which can be further used as a solid fuel or a carbonaceous adsorbent material via pyrolysis process.

    At the beginning of the 21 st century two urgent tasks which our global countries would face with could be the security of the alternative energy source as a preparation against the fossil energy exhaustion and the development of the clean energy source to protect the environment from pollution. The above two problems should be solved together. The bio diesel oil which is made by methylesterfication of bio oil has very low sulfur content than does the diesel oil. Therefore, there is a great possibility to solve the pollution problem caused by the exhaust gas from diesel engine vehicles. So, bio oil has been attracted with attentions as an alternative and clean energy source. Advanced countries began early to develop the bio diesel oil suitable to their respective conditions. Recently their production stage have reached to the commercial level partially. The sudden increase of energy demand followed by a rapid growth of industry and the serious situation about the environmental pollution caused by the exhaust has from diesel engine vehicles occupying 42% of distribution among all vehicles have called attention of our government to consider the importance of alternative and clean energy sources for the future on the national scale. This study is consisted of three main parts; - The development of production technology for bio diesel oil. - The development of the atomization improvement method and nozzle for high viscous vegetable oils. - Feasibility test of bio diesel engine.

    The combustion characteristics of bio-oils derived from rice husk and corn were studied by thermogravimetry analysis. According to the thermo-gravimetry (TG), differential thermogravimetry (DTG) and differential thermal analysis (DTA) curves of bio-oils in air and nitrogen atmosphere, we analyzed the combustion characteristics of different kinds of bio-oils in different atmospheres and worked out the combustion kinetics parameters of the bio-oil, providing reliable base data for the burning of bio-oil. The thermogravimetry indicated that the combustion process of bio-oil was divided into three stages. At the same time, the combustion process can be described by different order reaction models, and with the method of Coats-Redfern, the activation energy and frequency factor of different kinds of bio-oils were obtained.

    The market for bio fuels is subject to very high dynamics worldwide. Due to the extreme rise of the prices of raw materials as well as due to the retrogressive tax reductions for bio fuels in Germany one hardly invests in bio fuels. Substantial changes are experienced in the markets for fossil raw materials. The prices for agrarian raw material used in this contribution originate from the years 2006 and 2007. The effects of clearly higher oil prices on the bio fuel market are described. The investigation under consideration also deals with criteria of sustainability. The contribution of the individual bio fuels to the reduction of greenhouse gases is analyzed. The costs resulting from this are numerated. This enables a well-established comparison in which less representative bio fuels such as bio methane, BtL fuels and cellulose ethanol also are included.

    In fiscal 1999, the power conditioner which is the primary component of a photovoltaic power system was subjected to an accelerated test, etc., for the evaluation of its durability. For the accelerated test, operating conditions were so set that acceleration be implemented according to Arrhenius' law at ambient temperature 40 degrees C and relative humidity 36%. For the operation of the power conditioner, it was so set that the operation duration be 3.5 hours with a rest time of 4.5 hours for the night or the like. In the accelerated test conducted as in the previous year, 1100 cycles were completed recording the maximum, equivalent to approximately 8-1/2 years according to Arrhenius' law. After the test, no life affecting changes were detected in specimen device A, B, or D. Specimen C, however, failed during the test. As for the evaluation of durability of components, the electrolytic capacitor in the power conditioner was named. Reliability related literature was investigated and a durability evaluation test was started, with consideration given to the voltage to apply and service temperature. (NEDO)

    A new noncontacting dressing method using a laser as a tool has been studied and developed, in order to develop environment-compatible, energy-saving type machining machines. In this study, a cup-shaped grinding stone is developed for grinding performance testing by micron-order diamond abrasive powder, used for producing a grinding stone of superthin blades, is mixed with a cast iron binder, molded and sintered. In the grinding performance test, zirconia as a work is ground at a constant pressure to the grinding stone working surface before and after the laser-aided dressing, to analyze grinding/removal efficiency and grinding resistance. The grinding stone working surface conditions are observed by a scanning electron microscope after the laser-aided dressing, to correlate the surface conditions with the grinding data. It is found that the laser-aided dressing method needs no lubricant, is clean, cutting grinding time when incorporated in the machining process, suitable for grinding stone of low stiffness and ultrathin blades by use of ultrafine abrasive grains, suffering no exfoliation of the diamond grains, and hence economical.

    The above-named effort aims to work out modification plans and to predict their energy saving, energy substituting, and greenhouse gas reduction effects, and thereby to scout out a project which will effectively utilize flexibility-ensuring 'joint implementation' for the attainment of greenhouse gas reduction levels defined at COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). The results of assessment of this project based on the outcome of the survey show that (1) there is necessity for the project and that the presence of needs to be urgently satisfied is clear, that (2) energy saving, energy substituting, and greenhouse gas reduction effects are proved to exist and that the project is therefore an appropriate candidate for an activity to be implemented jointly, that (3) Russian agencies concerned are strongly interested in the project and that a sufficiently cooperative system will be available toward implementation, and that (4) there is an extremely large room for energy saving in the district heating oriented heat supply business in Russia and that probabilities are quite high that natural gas-fired turbine cogeneration plants capable of improving overall energy efficiency will enjoy extensive diffusion.

  3. Photobiology of Symbiodinium revisited: bio-physical and bio-optical signatures

    Light is often the most abundant resource within the nutrient-poor waters surrounding coral reefs. Consequently, zooxanthellae ( Symbiodinium spp.) must continually photoacclimate to optimise productivity and ensure coral success. In situ coral photobiology is becoming dominated by routine assessments using state-of-the-art non-invasive bio-optical or chlorophyll a fluorescence (bio-physical) techniques. Multiple genetic types of Symbiodinium are now known to exist; however, little focus has been given as to how these types differ in terms of characteristics that are observable using these techniques. Therefore, this investigation aimed to revisit and expand upon a pivotal study by Iglesias-Prieto and Trench (1994) by comparing the photoacclimation characteristics of different Symbiodinium types based on their bio-physical (chlorophyll a fluorescence, reaction centre counts) and bio-optical (optical absorption, pigment concentrations) ‘signatures’. Signatures described here are unique to Symbiodinium type and describe phenotypic responses to set conditions, and hence are not suitable to describe taxonomic structure of in hospite Symbiodinium communities. In this study, eight Symbiodinium types from clades and sub-clades (A-B, F) were grown under two PFDs (Photon Flux Density) and examined. The photoacclimation response by Symbiodinium was highly variable between algal types for all bio-physical and for many bio-optical measurements; however, a general preference to modifying reaction centre content over effective antennae-absorption was observed. Certain bio-optically derived patterns, such as light absorption, were independent of algal type and, when considered per photosystem, were matched by reaction centre stoichiometry. Only by better understanding genotypic and phenotypic variability between Symbiodinium types can future studies account for the relative taxonomic and physiological contribution by Symbiodinium to coral acclimation.

    Full Text Available An efficient gene transfer into target tissues and cells is needed for safe and effective treatment of genetic diseases like cancer. In this paper, we describe the development of a transport system and show its ability for transporting plasmids. This non-viral peptide-based BioShuttle-mediated transfer system consists of a nuclear localization address sequence realizing the delivery of the plasmid phNIS-IRES-EGFP coding for two independent reporter genes into nuclei of HeLa cells. The quantification of the transfer efficiency was achieved by measurements of the sodium iodide symporter activity. EGFP gene expression was measured with Confocal Laser Scanning Microscopy and quantified with biostatistical methods by analysis of the frequency of the amplitude distribution in the CLSM images. The results demonstrate that the “BioShuttle”-Technology is an appropriate tool for an effective transfer of genetic material carried by a plasmid.

  5. Stomatal Density and Bio-water Saving

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Bio-water saving is to increase water use efficiency of crops or crop yield per unit of water input. Plant water use efficiency is determined by photosynthesis and transpiration, for both of which stomata are crucial. Stomata are pores on leaf epidermis for both water and carbon dioxide fluxes that are controlled by two major factors: stomatal behavior and density. Stomatal behavior has been the focus of intensive research, while less attention has been paid to stomatal density. Recently, a number of genes controlling stomatal development have been identified. This review summarizes the recent progress on the genes regulating stomatal density, and discusses the role of stomatal density in plant water use efficiency and the possibility to increase plant water use efficiency, hence bio-water saving by genetically manipulating stomatal density.

    In recent years, personalized electronics for medical applications, particularly, have attracted much attention with the rise of smartphones because the coupling of such devices and smartphones enables the continuous health-monitoring in patients' daily life. Especially, it is expected that the high performance biomedical electronics integrated with the human body can open new opportunities in the ubiquitous healthcare. However, the mechanical and geometrical constraints inherent in all standard forms of high performance rigid wafer-based electronics raise unique integration challenges with biotic entities. Here, we describe materials and design constructs for high performance skin-mountable bio-integrated electronic devices, which incorporate arrays of single crystalline inorganic nanomembranes. The resulting electronic devices include flexible and stretchable electrophysiology electrodes and sensors coupled with active electronic components. These advances in bio-integrated systems create new directions in the personalized health monitoring and/or human-machine interfaces.

    The main conclusion in this report is that it is possible to make available about 14 TWh bio energy in Norway than what is used today to a charge that is located less than ca. 30 oere / kWh. Almost all this potential come from the forest and requires an increase in output up to the net sustained yield. Further 5 TWh may be available in the form of biogas at a cost that is both higher and have greater uncertainty than the fixed bio energy. It is set up a cost curve based on this work, which is quoted here. This reflects only the technical costs, and does not regard wages, commissions, taxes or fees. The value of alternative uses of biomass are not considered. The cost curve must therefore not be mixed with a supply curve. (eb)

    This CRADA was developed to enable ORNL to assist American Electronics, Inc. test a new technology--BioSAR. BioSAR is a an airborne, low frequency (80-120 MHz {approx} FM radio frequencies) synthetic aperture radar (SAR) technology which was designed and built for NASA by ZAI-Amelex under Patrick Johnson's direction. At these frequencies, leaves and small branches are nearly transparent and the majority of the energy reflected from the forest and returned to the radar is from the tree trunks. By measuring the magnitude of the back scatter, the volume of the tree trunk and therefore the biomass of the trunks can be inferred. The instrument was successfully tested on tropical rain forests in Panama. Patrick Johnson, with American Electronics, Inc received a Phase II SBIR grant from DOE Office of Climate Change to further test and refine the instrument. Mr Johnson sought ORNL expertise in measuring forest biomass in order for him to further validate his instrument. ORNL provided ground truth measurements of forest biomass at three locations--the Oak Ridge Reservation, Weyerhaeuser Co. commercial pine plantations in North Carolina, and American Energy and Power (AEP) Co. hardwood forests in southern Ohio, and facilitated flights over these forests. After Mr. Johnson processed the signal data from BioSAR instrument, the processed data were given to ORNL and we attempted to derive empirical relationships between the radar signals and the ground truth forest biomass measurements using standard statistical techniques. We were unsuccessful in deriving such relationships. Shortly before the CRADA ended, Mr Johnson discovered that FM signal from local radio station broadcasts had interfered with the back scatter measurements such that the bulk of the signal received by the BioSAR instrument was not backscatter from the radar but rather was local radio station signals.

    In this study, pyrolysis technique was utilized for converting palm oil sludge to value added materials: bio-oil (liquid fuel) and bio-char (soil amendment). The bio-oil yield obtained was 27.4±1.7 wt.% having a heating value of 22.2±3.7 MJ/kg and a negligible ash content of 0.23±0.01 wt.%. The pH of bio-oil was in alkaline region. The bio-char yielded 49.9±0.3 wt.%, which was further investigated for sorption efficiency by adsorbing metal (Cd(2+) ions) from water. The removal efficiency of Cd(2+) was 89.4±2%, which was almost similar to the removal efficiency of a commercial activated carbon. The adsorption isotherm was well described by Langmuir model. Therefore, pyrolysis is proved as an efficient tool for palm oil sludge management, where the waste was converted into valuable products.

  17. Bio-diesel fuels production: Feasibility studies

    International Nuclear Information System (INIS)

    This paper reviews the efforts being made by Italy's national government and private industry to develop diesel engine fuels derived from vegetable oils, in particular, sunflower seed oil. These fuels are being promoted in Italy from the environmental protection stand-point in that they don't contain any sulfur, the main cause of acid rain, and from the agricultural stand-point in that they provide Italian farmers, whose food crop production capacity is limited due to European Communities agreements, with the opportunity to use their set-aside land for the production of energy crops. This paper provides brief notes on the key performance characteristics of bio-diesel fuels, whose application doesn't require any modifications to diesel engines, apart from minor adjustments to the air/fuel mix regulating system, and assesses commercialization prospects. Brief mention is made of the problems being encountered by the Government in the establishing fair bio-fuel production tax rebates which are compatible with the marketing practices of the petroleum industry. One of the strategies being considered is to use the bio-fuels as additives to be mixed with conventional fuel oils so as to derive a fuel which meets the new European air pollution standards

    In summary, microfluidic-BioMEMS platforms are increasingly contributing to tissue engineering in many different ways. First, the accurate control of the cell environment in settings suitable for cell screening and with imaging compatibility is greatly advancing our ability to optimize cell sources for a variety of tissue-engineering applications. Second, the microfluidic technology is ideal for the formation of perfusable networks, either to study their stability and maturation or to use these networks as templates for engineering vascularized tissues. Third, the approaches based on microfluidic and BioMEMS devices enable engineering and the study of minimally functional modules of complex tissues, such as liver sinusoid, kidney nephron, and lung bronchiole. This brief article highlighted some of the unique advantages of this elegant technology using representative examples of tissue-engineering research. We focused on some of the universal needs of the area of tissue engineering: tissue vascularization, faithful recapitulation in vitro of functional units of our tissues and organs, and predictable selection and differentiation of stem cells that are being addressed using the power and versatility of microfluidic-BioMEMS platforms.

    Full Text Available The barrier resistance and wettability of papers are commonly controlled by the application of petroleum-based derivatives such as polyethylene, waxes and/or fluor- derivatives as coating. While surface hydrophobicity is improved by employing these polymers, they have become disfavored due to limitations in fossil-oil resources, poor recyclability, and environmental concerns on generated waste with lack of biodegradation. Alternatively, biopolymers including polysaccharides, proteins, lipids and polyesters can be used to formulate new pathways for fully bio-based paper coatings. However, difficulties in processing of most biopolymers may arise due to hydrophilicity, crystallization behavior, brittleness or melt instabilities that hinder a full exploitation at industrial scale. Therefore, blending with other biopolymers, plasticizers and compatibilizers is advantageous to improve the coating performance. In this paper, an overview of barrier properties and processing of bio-based polymers and their composites as paper coating will be discussed. In particular, recent technical advances in nanotechnological routes for bio-based nano- composite coatings will be summarized, including the use of biopolymer nanoparticles, or nanofillers such as nanoclay and nanocellulose. The combination of biopolymers along with surface modification of nanofillers can be used to create hierarchical structures that enhance hydrophobicity, complete barrier protection and functionalities of coated papers.

    Due to depletion of fossil fuel, bio-fuels have generated a significant interest as an alternative fuel for the future. The use of bio-fuels to fuel gas turbine seems a viable solution for the problems of decreasing fossil-fuel reserves and environmental concerns. Bio-fuels are alternative fuels, made from renewable sources and having environmental benefit. In recent years, the desire for energy independence, foreseen depletion of nonrenewable fuel resources, fluctuating petroleum fuel costs, the necessity of stimulating agriculture based economy, and the reality of climate change have created an interest in the development of bio-fuels. The application of bio-fuels in automobiles and heating applications is increasing day by day. Therefore the use of these fuels in gas turbines would extend this application to aviation field. The impact of costly petroleum-based aviation fuel on the environment is harmful. So the development of alternative fuels in aviation is important and useful. The use of liquid and gaseous fuels from biomass will help to fulfill the Kyoto targets concerning global warming emissions. In addition, to reduce exhaust emission waste gases and syngas, etc., could be used as a potential gas turbine fuel. The term bio-fuel is referred to alternative fuel which is produced from biomass. Such fuels include bio-diesel, bio-ethanol, bio-methanol, pyrolysis oil, biogas, synthetic gas (dimethyl ether), hydrogen, etc. The bio-ethanol and bio-methanol are petrol additive/substitute. Bio-diesel is an environment friendly alternative liquid fuel for the diesel/aviation fuel. The gas turbine develops steady flame during its combustion; this feature gives a flexibility to use alternative fuels. Therefore so the use of different bio-fuels in gas turbine has been investigated by a good number of researchers. The suitability and modifications in the existing systems are also recommended.

    This invention relates to a method and device to produce esterified, olefinated/esterified, or thermochemolytic reacted bio-oils as fuels. The olefinated/esterified product may be utilized as a biocrude for input to a refinery, either alone or in combination with petroleum crude oils. The bio-oil esterification reaction is catalyzed by addition of alcohol and acid catalyst. The olefination/esterification reaction is catalyzed by addition of resin acid or other heterogeneous catalyst to catalyze olefins added to previously etherified bio-oil; the olefins and alcohol may also be simultaneously combined and catalyzed by addition of resin acid or other heterogeneous catalyst to produce the olefinated/esterified product.

  4. Bio-Chemicals Derived from Waste: Building on the Concept of a Bio-Refinery

    International Nuclear Information System (INIS)

    The work presented here has looked into the thermal-conversion of wheat and barley spent grains (SG). Wheat fermentation was carried in the laboratory to get a mashed product while barley grain residues were sourced from a local brewing company. Pyrolysis carried at 460, 520 and 540 Degree C at ambient conditions of pressure in a bench scale fluidized bed reactor resulted in producing bio-oil, charcoal and non-condensable gases. These products were characterized by using the Gas Chromatography Mass Spectrometry (GC-MS), Differential Thermo-glavemetric Analysis (DTG), Elemental Analyzer (E.A) and a Bomb Calorimeter. The final pyrolysis product analysis revealed that the bio-oil production yields and Higher Heating Value (HHV) largely depended on the pyrolysis temperature and the sample type. In comparison with original raw grain samples, the analysis of thermally treated (pyrolysis) spent grains revealed the presence of high carbon and low oxygen contents. Results gathered in this work have shown that high bio-crude-oil production yields can be obtained at 520 Degree C (53 and 37wt percentage bio-oil from wheat and barley SG). Pyrolysis of wheat and barley SG resulted in giving a Higher Heating Value (HHV) of 21.80 and 21.86 MJ/kg at 540 and 460 Degree C, which is considerably more in comparison to their virgin counterparts. This suggested route thus has a potential for further up-gradation of waste bio-mass for use as an intermediate fuel or as a raw material source for producing other bio-chemicals. (author)

Globally primary energy consumption (related carbon emissions) is currently equivalent to ∼0.06% of the incident solar energy, and 43% of the energy (carbon) captured by photosynthesis. The nations fall into three categories. Those with primary energy consumption that is: 1–10% (Japan, Korea and Singapore); ∼0.1% (China, UK and the US) and; 0.1–0.01% (Australia, Brazil, Papua New Guinea, New Zealand and Sweden) of incident solar radiation. The percentage of energy captured in biomass follows this pattern, but generally lower by ∼3 orders of magnitude. The energy content of traded wheat, corn and rice represents conversion efficiencies of solar radiation of 0.08–0.17% and for sugar close to 1%, ignoring energy use in production and conversion of biomass to fuels. The study implies that bio-fuels or bio-sequestration can only be a small part of an inclusive portfolio of actions towards a low carbon future and minimised net emissions of carbon to the atmosphere. - Highlights: • Global energy consumption is ∼0.06% of solar; 43% of net primary production. • 11 nations studied fall into 3 groups: consumption/solar=1–10%; ∼0.1%; 0.1–0.01%. • % of energy captured in biomass is lower by ∼3 orders of magnitude. • Crops and natural ecosystems capture 0.1–0.3% and sugar 1% of solar energy. • Significant bio-energy/carbon sequestration via biomass is unrealistic

    Full Text Available The work presented here has looked into the thermal-conversion of wheat and barley spent grains (SG. Wheat fermentation was carried in the laboratory to get a mashed product while barley grain residues were sourced from a local brewing company. Pyrolysis carried at 460, 520 and 540 oC at ambient conditions of pressure in a bench scale fluidized bed reactor resulted in producing bio-oil, charcoal and non-condensable gases. These products were characterized by using the Gas Chromatography Mass Spectrometry (GC-MS, Differential Thermo-glavemetric Analysis (DTG, Elemental Analyzer (E.A and a Bomb Calorimeter. The final pyrolysis product analysis revealed that the bio-oil production yields and Higher Heating Value (HHV largely depended on the pyrolysis temperature and the sample type. In comparison with original raw grain samples, the analysis of thermally treated (pyrolysis spent grains revealed the presence of high carbon and low oxygen contents. Results gathered in this work have shown that high bio-crude-oil production yields can be obtained at 520 oC (53 and 37wt% bio-oil from wheat and barley SG. Pyrolysis of wheat and barley SG resulted in giving a Higher Heating Value (HHV of 21.80 and 21.86 MJ/kg at 540 and 460oC, which is considerably more in comparison to their virgin counterparts. This suggested route thus has a potential for further up-gradation of waste bio-mass for use as an intermediate fuel or as a raw material source for producing other bio-chemicals.

    International Nuclear Information System (INIS)

    Typical operations taking place at wastewater treatment plants, especially those involving aeration and mechanical agitation of raw wastewater, represent one of the main sources of bio aerosols that, if inhaled, could pose a biologic hazard to site workers and local residents. Six different wastewater treatment plants from southeast Spain were monitories in order to identify the main bio aerosol sources and to evaluate the airborne microorganisms levels to which workers may be exposed to. Air samples were taken from selected locations by using a single stage impactor. (Author)

  10. Bio diesel- the Clean, Green Fuel for Diesel Engines

    International Nuclear Information System (INIS)

    Natural, renewable resources such as vegetable oils, animal fats and recycled restaurant greases can be chemically transformed into clean burning bio diesel fuels (1). Just like petroleum diesel, bio diesel operates in combustion-ignition engines. Blends of up to 20% bio diesel (mixed with petroleum diesel fuels) can be used in nearly all diesel equipment and are compatible with most storage and distribution equipment. Using bio diesel in a conventional diesel engine substantially reduces emissions of unburned hydrocarbons, carbon monoxide, sulphates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons, and particulate matter. The use of bio diesel has grown dramatically during the last few years. Egypt has a promising experiment in promoting forestation by cultivation of Jatropha plant especially in luxor and many other sites of the country. The first production of the Egyptian Jatropha seeds oil is now under evaluation to produce a cost-competitive bio diesel fuel

    Functional nanoscale materials that possess specific physical or chemical properties can leverage energy transduction in vivo. Once these materials integrate with biomolecules they combine physical properties of inorganic material and the biorecognition capabilities of bio-organic moieties. Such nano-bio hybrids can be interfaced with living cells, the elementary functional units of life. These nano-bio systems are capable of bio-manipulation or actuation via altering intracellular biochemical pathways. Thus, nano-bio conjugates are appealing for a wide range of applications from the life sciences and nanomedicine to catalysis and clean energy production. Here we highlight recent progress in our efforts to develop smart nano-bio hybrid materials, and to study their performance within cellular machinery under application of external stimuli, such as light or magnetic fields.

  19. Electro-active bio-films: formation, characterization and mechanisms

    International Nuclear Information System (INIS)

    Some bacteria, which are able to exchange electrons with a conductive material without mediator form on conductive surfaces electro-active bio-films. This bacterial property has been recently discovered (2001). Objectives of this work are to develop electro-active bio-films in various natural environments from indigenous flora, then through complementary electrochemical techniques (chrono-amperometry and cyclic voltammetry), to evaluate electro-activity of isolates coming from so-formed bio-films and to characterize mechanisms of electron transfer between bacteria and materials. First, electro-active bio-films have been developed under chrono-amperometry in garden compost and in water coming from Guyana mangrove. These bio-films were respectively able to use an electrode as electron acceptor (oxidation) or as electron donor (reduction). In compost, results obtained in chrono-amperometry and cyclic voltammetry suggest a two-step electron transfer: slow substrate consumption, then rapid electron transfer between bacteria and the electrode. Thereafter, the ability to reduce oxygen was demonstrated with cyclic voltammetry for facultative aerobic isolates from compost bio-films (Enterobacter spp. and Pseudomonas spp.) and for aerobic isolates obtained from marine electro-active bio-films (Roseobacter spp. in majority). Finally, bio-films inducing current increase in chrono-amperometry were developed in bioreactor with synthetic medium from a pure culture of isolates. Hence, for the first time, electro-activity of several anaerobic strains of Geobacter bremensis isolated from compost bio-films was highlighted. (author)

    BioLayout Express (3D) is a network analysis tool designed for the visualisation and analysis of graphs derived from biological data. It has proved to be powerful in the analysis of gene expression data, biological pathways and in a range of other applications. In version 3.2 of the tool we have introduced the ability to import, merge and display pathways and protein interaction networks available in the BioPAX Level 3 standard exchange format. A graphical interface allows users to search for pathways or interaction data stored in the Pathway Commons database. Queries using either gene/protein or pathway names are made via the cPath2 client and users can also define the source and/or species of information that they wish to examine. Data matching a query are listed and individual records may be viewed in isolation or merged using an 'Advanced' query tab. A visualisation scheme has been defined by mapping BioPAX entity types to a range of glyphs. Graphs of these data can be viewed and explored within BioLayout as 2D or 3D graph layouts, where they can be edited and/or exported for visualisation and editing within other tools. PMID:25949802

    The understanding and characterization ofthe fundamental processes of the function of biological systems underpins many of the important challenges facing American society, from the pathology of infectious disease and the efficacy ofvaccines, to the development of materials that mimic biological functionality and deliver exceptional and novel structural and dynamic properties. These problems are fundamentally complex, involving many interacting components and poorly understood bio-chemical kinetics. We use the basic science of statistical physics, kinetic theory, cellular bio-chemistry, soft-matter physics, and information science to develop cell level models and explore the use ofbiomimetic materials. This project seeks to determine how cell level processes, such as response to mechanical stresses, chemical constituents and related gradients, and other cell signaling mechanisms, integrate and combine to create a functioning organism. The research focuses on the basic physical processes that take place at different levels ofthe biological organism: the basic role of molecular and chemical interactions are investigated, the dynamics of the DNA-molecule and its phylogenetic role are examined and the regulatory networks of complex biochemical processes are modeled. These efforts may lead to early warning algorithms ofpathogen outbreaks, new bio-sensors to detect hazards from pathomic viruses to chemical contaminants. Other potential applications include the development of efficient bio-fuel alternative-energy processes and the exploration ofnovel materials for energy usages. Finally, we use the notion of 'coarse-graining,' which is a method for averaging over less important degrees of freedom to develop computational models to predict cell function and systems-level response to disease, chemical stress, or biological pathomic agents. This project supports Energy Security, Threat Reduction, and the missions of the DOE Office of Science through its efforts to

It assumes the conductors are infinitesimally thin and can be described as either point sequences or circular coils. The code can calculate both the magnetic field as well as the vector potential due to the coils. The fields can be reduced very near the coils to avoid singular behaviour caused by the thin conductor approximation.

    In 2012 bio-energy contributed over 71 PJ to the Dutch energy supply, a rise of almost 2 PJ over 2011. This means that 75% of the renewable energy consumed in the Netherlands is now derived from biomass. The growth is due mainly to the increase in the mandatory biotransport fuel percentage from 4.25% to 4.5%. The use of energy from 'other biomass combustion' (incl. paper sludge, green waste and chicken excrement) recovered to the level of 2010, following a marked drop in 2011 due to plant maintenance, termination of the MEP ('Environmental Quality of Power Generation') subsidy scheme and high biomass prices. At large power stations there was a considerable decrease in co-incineration of biomass because of incidents (a fire at the Nijmegen coal-fired plant) and a maintenance backlog (at the Amer power station). These are some of the results reported in the 'Bio-energy status document 2012', prepared by CE Delft for NL Agency. In addition to a review and characterisation of the current situation, the report contains an update on government policies on bio-energy and a review of the sources and sustainability of the biomass used in the Netherlands [Dutch] De bijdrage van bio-energie aan de Nederlandse energievoorziening bedroeg in 2012 ruim 71 PJ, een stijging van bijna 2 PJ ten opzichte van 2011. Daarmee is 75% van het verbruik van hernieuwbare energie in Nederland afkomstig van bio-energie. De stijging wordt vooral veroorzaakt door de oplopende bijmengplicht van biotransportbrandstoffen van 4,25% naar 4,5%. Verbruik van energie uit 'overige biomassaverbranding' (o.a. papierslib, groenafval en kippenmest) herstelde zicht tot het niveau van 2010, na een forse daling in 2011 door onderhoud aan installaties, afloop van MEP-subsidies en hoge prijzen van biomassa.

    With the advent of significant establishment and development of Internet facilities and computational infrastructure, an overview on bio/chemoinformatics is presented along with its multidisciplinary facts, promises and challenges. The Government of India has paved the way for more profound research in biological field with the use of computational facilities and schemes/projects to collaborate with scientists from different disciplines. Simultaneously, the growth of available biomedical data has provided fresh insight into the nature of redundant and compensatory data. Today, bioinformatics research in India is characterized by a powerful grid computing systems, great variety of biological questions addressed and the close collaborations between scientists and clinicians, with a full spectrum of focuses ranging from database building and methods development to biological discoveries. In fact, this outlook provides a resourceful platform highlighting the funding agencies, institutes and industries working in this direction, which would certainly be of great help to students seeking their career in bioinformatics. Thus, in short, this review highlights the current bio/chemoinformatics trend, educations, status, diverse applicability and demands for further development. PMID:25159593

    New technologies for reducing the sludge production of municipal or industrial WWTP have been appeared during the last few years. One of these innovative processes, Bio THELYS, consists in enhancing the biodegradability of sludge by a stage of thermal hydrolysis. The hydrolysed sludge could then be sent upstream to a biological step either aerobic or anaerobic. The objective is to increase the global mineralisation of the pollution entering the WWTP in order to decrease the waste leaving it, i.e. mainly the sludge. A 2500 population equivalent prototype was installed on a WWTP, in Champagne - France. Thermal hydrolysis is carried out under a temperature of 150-185{sup o}C, a pressure of 10-15 bar with an hydraulic retention time of 30-60 minutes. Thermal hydrolysis is implemented on a secondary recycling loop on the biological basin. Trials started in 1999 and are still on operation. A close monitoring of the WWTP was set up focusing especially on sludge characteristics, treated water quality, yield of sludge production reduction and plant operation. Bio THELYS could achieve a reduction in sludge production up to 70% on the plant. (author)

    The Bermuda BioOptics Project (BBOP) is a collaborative effort between the Institute for Computational Earth System Science (ICESS) at the University of California at Santa Barbara (UCSB) and the Bermuda Biological Station for Research (BBSR). This research program is designed to characterize light availability and utilization in the Sargasso Sea, and to provide an optical link by which biogeochemical observations may be used to evaluate bio-optical models for pigment concentration, primary production, and sinking particle fluxes from satellite-based ocean color sensors. The BBOP time-series was initiated in 1992, and is carried out in conjunction with the U.S. JGOFS Bermuda Atlantic Time-series Study (BATS) at the Bermuda Biological Station for Research. The BATS program itself has been observing biogeochemical processes (primary productivity, particle flux and elemental cycles) in the mesotrophic waters of the Sargasso Sea since 1988. Closely affiliated with BBOP and BATS is a separate NASA-funded study of the spatial variability of biogeochemical processes in the Sargasso Sea using high-resolution AVHRR and SeaWiFS data collected at Bermuda (N. Nelson, P.I.). The collaboration between BATS and BBOP measurements has resulted in a unique data set that addresses not only the SIMBIOS goals but also the broader issues of important factors controlling the carbon cycle.

    As part ofthe Consortium for Research on Renewable Industrial Materials' Phase I life-cycle assessments ofbiofuels, lifecycle inventory burdens from the production of bio-oil were developed and compared with measures for residual fuel oil. Bio-oil feedstock was produced using whole southern pine (Pinus taeda) trees, chipped, and converted into bio-oil by fast pyrolysis. Input parameters and mass and energy balances were derived with Aspen. Mass and energy balances were input to SimaPro to determine the environmental performance of bio-oil compared with residual fuel oil as a heating fuel. Equivalent functional units of 1 MJ were used for demonstrating environmental preference in impact categories, such as fossil fuel use and global warming potential. Results showed near carbon neutrality of the bio-oil. Substituting bio-oil for residual fuel oil, based on the relative carbon emissions of the two fuels, estimated a reduction in CO2 emissions by 0.075 kg CO2 per MJ of fuel combustion or a 70 percent reduction in emission over residual fuel oil. The bio-oil production life-cycle stage consumed 92 percent of the total cradle-to-grave energy requirements, while feedstock collection, preparation, and transportation consumed 4 percent each. This model provides a framework to better understand the major factors affecting greenhouse gas emissions related to bio-oil production and conversion to boiler fuel during fast pyrolysis.

    This research reports on the development of an innovative biosensor, known as BioCapacitor, in which biological recognition elements are combined with a capacitor functioning as the transducer. The analytical procedure of the BioCapacitor is based on the following principle: a biocatalyst, acting as a biological recognition element, oxidizes or reduces the analyte to generate electric power, which is then charged into a capacitor via a charge pump circuit (switched capacitor regulator) until the capacitors attains full capacity. Since the charging rate of the capacitor depends on the biocatalytic reaction of the analyte, the analyte concentration can be determined by monitoring the time/frequency required for the charge/discharge cycle of the BioCapacitor via a charge pump circuit. As a representative model, we constructed a BioCapacitor composed of FAD-dependent glucose dehydrogenase (FADGDH) as the anodic catalyst, and attempted a glucose measurement. Charge/discharge frequency of the BioCapacitor increased with the increasing glucose concentration, exhibiting good correlation with glucose concentration. We have also constructed a wireless sensing system using the BioCapacitor combined with an infrared light emitting diode (IRLED), an IR phototransistor system. In the presence of glucose, the IRLED signal was observed due to the discharge of the BioCapacitor and detected by an IR phototransistor in a wireless receiver. Therefore, a BioCapacitor employing FADGDH as its anodic catalyst can be operated as a self-powered enzyme sensor. PMID:19013784

    The deployment of bio fuels has generated a significant controversy in the energy, agricultural and environmental fields. Governments and promoters around the world have advocated for developing bio fuels based on their potential contribution to emissions reduction and energy security. But opposition to bio fuels has growth in the last years. Environmental NGO's and other stake holders have called for a review of the environmental and social sustainability of energy crops. This controversy has characterized the public debate around bio fuels. In this context, and given the need to improve public involvement in energy technologies, this article reports an investigation of Spanish citizens' perceptions about bio fuels. The study investigated the perceptions of informed citizens and the reasoning basis underlying beliefs and attitudes. The study finds an initial positive association of bio fuels to a clean and natural fuel that is mitigated by participants' concerns on the practical usage of bio fuels and the social and environmental impacts. Study participants' reactions show the need to differentiate among the diverse groups of publics holding differing views and a different reaction to information on the benefits and costs of bio fuels.

  10. The environmentally friendly technology for bio fuel production

    International Nuclear Information System (INIS)

    Full text: Bio fuel production and use have been discussed this time in EC and in Latvia as alternative energy sources. The national resources allow producing liquid fuels - bio diesel and bi oethanol from rape seeds and grain correspondingly. Liquid bio fuels can be recommended especially for auto transport in big towns to reduce the pollution of air. A system for environmentally friendly production of bio fuel from agricultural raw materials has been developed, which permit a complex utilization of byproducts an wastes for obtaining of valuable food-stuffs and industrial products, providing the agricultural production requirements and supporting with local mineral fertilizers. Such a bio fuel production includes the agricultural and industrial productions in a united biotechnological system. Production objects of system interact: the products, by-products and wastes from one object are used as raw materials, auxiliary materials or heat carriers in other system's objects. This integrated agro-industrial production system would allow the production of feeds and chemical products, along with bio fuels. In this work, a model of a system for a conventional administrative rural region is presented, exemplified with the case of Latvia. The model is developed for three forms of bio fuel production, i.e. ethanol, bio diesel and biogas as local energy source. Bio diesel is produced using ethanol as transesterifying agent of rape-seed oil fatty acids. This bio diesel is a blend of rape-seed oil fatty acid ethyl esters (REE) and consists solely from renewable raw materials. The capacity of distillery of system is 40 million litters per year and bio diesel 35000 ton. Important for agriculture is protein reach press cakes the byproduct from bio diesel production (66000 t/y). This byproduct can be exported as well. Biogas reactors of system can be used for utilization of wastes from town if necessary. Recommended bio system occupates up to 150.000 ha of agriculture lands

    The introduction of antioxidants in polymers is the main way to prevent or delay the degradation process. In particular natural antioxidants receive attention in the food industry also because of their presumed safety. In this work bio-polymers, i.e. a commercial starch-based polymer (Mater-Bi®) and a bio-polyester (PLA), and a bio-polyether (PEO) were additivated with quercetin, a natural flavonoid antioxidants, in order to formulate bio-based films for ecosustainable packaging and outdoor applications. The photo-oxidation behavior of unstabilized and quercetin stabilized films was analyzed and compared with the behavior of films additivated with a commercial synthetic light stabilizer. The quercetin is able to slow down the photo-degradation rate of all bio-polymeric films investigated in similar way to the synthetic stabilizer.

    The move towards a green bio-oil extraction technique is highlighted in this paper. The commonly practised organic solvent oil extraction technique could be replaced with a modified microwave extraction. Jatropha seeds (Jatropha curcas) were used to extract bio-oil. Clean samples were heated in an oven at 110 ° C for 24 hours to remove moisture content and ground to obtain particle size smaller than 500μm. Extraction was carried out at different extraction times 15 min, 30 min, 45 min, 60 min and 120 min to determine oil yield. The biooil yield obtained from microwave assisted extraction system at 90 minutes was 36% while that from soxhlet extraction for 6 hours was 42%. Bio-oil extracted using the microwave assisted extraction (MAE) system could enhance yield of bio-oil compared to soxhlet extraction. The MAE extraction system is rapid using only water as solvent which is a nonhazardous, environment-friendly technique compared to soxhlet extraction (SE) method using hexane as solvent. Thus, this is a green technique of bio-oil extraction using only water as extractant. Bio-oil extraction from the pyrolysis of empty fruit bunch (EFB), a biomass waste from oil palm crop, was enhanced using a biocatalyst derived from seashell waste. Oil yield for non-catalytic extraction was 43.8% while addition of seashell based biocatalyst was 44.6%. Oil yield for non-catalytic extraction was 43.8% while with addition of seashell-based biocatalyst was 44.6%. The pH of bio-oil increased from 3.5 to 4.3. The viscosity of bio-oil obtained by catalytic means increased from 20.5 to 37.8 cP. A rapid and environment friendly extraction technique is preferable to enhance bio-oil yield. The microwave assisted approach is a green, rapid and environmental friendly extraction technique for the production of bio-oil bearing crops.

    An increasing number of countries is setting objectives and obligations to replace part of their fossil natural gas consumptions by bio-methane to reduce CO2 emissions. The production of bio-methane via digestion has been developed and is implemented on a small scale. The limited amount of suitable digestible feedstock demands for development of a technology which can convert a wider range of biomass fuels, such as wood into bio-methane. Gasification is such a route. Gasification technology offers the possibility to convert lignocellulosic biomass (e.g. residual wood) into a combustible gas. This gas can be converted into natural gas quality gas (bio-methane) by catalytic processes. Bio-fuels such as bio-methane produced from biomass have the potential to become a CO2 negative fuel, because part of the biomass carbon is separated as CO2 during the production process. If this pure CO2 stream is sequestrated, these bio-fuels become even CO2 negative. This might be an attractive option for reducing the level of greenhouse gases in the atmosphere. Several bio-methane demonstration projects are underway based on thermal gasification of woody biomass. The most well known is the 20 MWth GoBiGas project in Gothenburg by Goeteborg Energi and E.ON. ECN (Energy research Centre of the Netherlands) has developed an alternative gasification process (MILENA), optimized for the production of bio-methane. This system has an overall efficiency of 70% from wood to bio-methane. The technology is demonstrated at lab scale (30 kWth) and pilot scale (800 kWth). A 12 MWth demonstration plant is under preparation in close cooperation with the HVC Group who plan to act as launching customer.

    We previously developed the Bio-Pick, Place, and Perfuse (Bio-P3) instrument to fabricate large perfusable tissue constructs by stacking and aligning scaffold-free living microtissues with integrated lumens. The Bio-P3 required an actuating mechanism to manipulate living microtissues of various sizes and shapes that are fragile, and must remain in an aqueous environment. The optical transparency of the Bio-P3 gripping device was essential to provide unobstructed visuals for accurate alignment of microtissues. We previously engineered a pilot fluid force-driven bio-gripper that can pick-and-place microtissue in planar position without causing cellular damage by pulling culture medium through track-etched membrane-integrated cell culture inserts. In this study, we invented a new flexible bio-gripper design that maximized the bio-gripper utilities. We utilized experimental approaches, multivariate analyzes, and theoretical modeling to elucidate how membrane characteristics (pore size, pore density, membrane thickness, membrane area, and surface chemistry) altered bio-gripper robustness and the flow rate (Q(c)) required for successful gripping. We devised two standardized tests and synthetic parts that mimicked microtissues, to systematically quantify bio-gripper performance. All thirteen syringe pump-driven bio-grippers except one successfully gripped and released synthetic parts with values of Q(c) that coincided with our mathematical simulation of the fluid mechanics of gripping. The bio-gripper could grip synthetic parts of various sizes, shapes and masses, demonstrating the robustness of the actuating mechanism. Multivariate analysis of experimental data indicated that both membrane porosity and thickness modulated Q(c), and in addition, revealed that membrane pore density determined membrane optical transparency. Fabricating large tissue constructs requires repeated stacking of microtissues. We showed that one bio-gripper could pick-and-place living microtissues

    Full Text Available The results of this paper are the product of a broader research on political participation. The expressions of young university students are there analyzed about civic education received at school related to political participation. Three focus groups were held with freshmen at Universidad del Bio-Bio, Chile. The results show that the vision of young people about the formation received is rather critical. On the one hand, the need for civic education is identified as that which allows to address the complexity of political activity. Secondly, it is found that school education does not respond to this need, since it is qualified as poor and biased. For students, education must play a politicizing role, providing inputs to influence social change.

    The dispersibility of bio-molecules such as lecithins on the surface of ZnO nanowires are investigated for biosensor applications. Lecithins can be absorbed on an as-synthesized ZnO nanowire surface in the form of sub-micro sized clusters, while scattering well on those annealed under oxygen atmosphere. Wettability analysis reveals that the as-synthesized ZnO nanowires bear a super-hydrophobic surface, which convents to superhydrophilic after oxygen annealing. First-principles calculations indicate that the adsorption energy of ZnO with water is about 0.2eV at a distance of 2 A when it is superhydrophilic, suggesting that lecithin can be absorbed on the hydrophilic surface stably at this distance and the bio-affinity can be enhanced under this condition.%The dispersibility of bio-molecules such as lecithins on the surface of ZnO nanowires are investigated for biosensor applications.Lecithins can be absorbed on an as-synthesized ZnO nanowire surface in the form of sub-micro sized clusters,while scattering well on those annealed under oxygen atmosphere.Wettability analysis reveals that the as-synthesized ZnO nanowires bear a super-hydrophobic surface,which convents to superhydrophilic after oxygen annealing.First-principles calculations indicate that the adsorption energy of ZnO with water is about 0.2 eV at a distance of 2(A) when it is superhydrophilic,suggesting that lecithin can be absorbed on the hydrophilic surface stably at this distance and the bio-affinity can be enhanced under this condition.

    Completely bio-based poly(limonene carbonate) is a thermoplastic polymer, which can be synthesized by copolymerization of limonene oxide (derived from limonene, which is found in orange peel) and CO2. Poly(limonene carbonate) has one double bond per repeating unit that can be exploited for further chemical modifications. These chemical modifications allow the tuning of the properties of the aliphatic polycarbonate in nearly any direction. Here we show synthetic routes to demonstrate that poly(limonene carbonate) is the perfect green platform polymer, from which many functional materials can be derived. The relevant examples presented in this study are the transformation from an engineering thermoplastic into a rubber, addition of permanent antibacterial activity, hydrophilization and even pH-dependent water solubility of the polycarbonate. Finally, we show a synthetic route to yield the completely saturated counterpart that exhibits improved heat processability due to lower reactivity. PMID:27302694

    To degrade lignin which is the most difficult fraction to be degraded in cellulosic bio resources and reuse as valuable formats, the improved strains of edible mushroom with more highly ligno cellulolytic activity were induced by γ-ray radiation and analysed their physiological and genetical characteristics. Mnp, Lac gene related to be the above were cloned. From the base sequence analysis, it seemed that there could be specific radiation-sensitive spots on the gene of mutants. anti mutagenicity, glyceollin elicitation activity and synergistic effects with indole acetic acid were found promisingly from the extracts of their cultural byproducts. And also were the byproducts expected to be useful for the candidate of subsidiary animal feed. By the radiation mutation, it seemed to be possible to induce the improved strains of antifungal activity, too. (author)

    Biological aspects of electromagnetic compatibility (Bio-EMC) have been studied by EMC Research Group of CRL. There are two main subjects in the field. One is related to rules and regulations of electromagnetic-wave hazards, especially development of standard estimation methods of electromagnetic power deposited in human bodies exposed to microwaves from cellular telephones or VHF-band radio waves. Another is development of exposure setups for laboratory animals used in biological studies on health effects of electromagnetic waves and their dosimetry. Novel phantoms are also being developed in order to perform highly accurate dosimetry in above studies. It is expected that these studies contribute development of compliance tests for radiofrequency protection guidelines and improvement of rationale of those guidelines, which consequently provides safety environment including appropriate radio wave applications.

  12. Bio-switches: what makes them robust?

    Science.gov (United States)

    Slepchenko, Boris M; Terasaki, Mark

    2004-08-01

    Ideas of how a system of interacting enzymes can act as a switch are based on the concept of bistability of a biochemical network. This means that, because of the very structure of a signaling pathway, the system can be in one of two stable steady states: active or inactive. Switching from one state to another may then occur in response to external stimuli or as a result of internal development. However, the bistability of a biochemical network might not be robust enough to be the sole mechanism behind bio-switching. On the basis of recent experimental data on the cell-cycle G2/M transition during starfish oocyte meiotic maturation, it is shown that cooperative phenomena--such as phase changes associated with clustering, dissolution of aggregates and so on--may play central roles in providing a decisive and irreversible transition.

  13. Utilization of oil palm tree residues to produce bio-oil and bio-char via pyrolysis

    International Nuclear Information System (INIS)

    Highlights: • About 14.72% of the total landmass in Malaysia was used for oil palm plantations. • Oil palm tree residues were pyrolyzed to produce bio-oil and bio-char. • The process was performed at a temperature of 500 °C and reaction time of 60 min. • Characterization of the products was performed. - Abstract: Oil palm tree residues are a rich biomass resource in Malaysia, and it is therefore very important that they be utilized for more beneficial purposes, particularly in the context of the development of biofuels. This paper described the possibility of utilizing oil palm tree residues as biofuels by producing bio-oil and bio-char via pyrolysis. The process was performed in a fixed-bed reactor at a temperature of 500 °C, a nitrogen flow rate of 2 L/min and a reaction time of 60 min. The physical and chemical properties of the products, which are important for biofuel testing, were then characterized. The results showed that the yields of the bio-oil and bio-char obtained from different residues varied within the ranges of 16.58–43.50 wt% and 28.63–36.75 wt%, respectively. The variations in the yields resulted from differences in the relative amounts of cellulose, hemicellulose, lignin, volatiles, fixed carbon, and ash in the samples. The energy density of the bio-char was found to be higher than that of the bio-oil. The highest energy density of the bio-char was obtained from a palm leaf sample (23.32 MJ/kg), while that of the bio-oil was obtained from a frond sample (15.41 MJ/kg)

  14. Bio-indicators for radiation dose assessment

    International Nuclear Information System (INIS)

    In nuclear facilities, such as Chalk River Laboratories, dose to the atomic radiation workers (ARWs) is assessed routinely by using physical dosimeters and bioassay procedures in accordance with regulatory recommendations. However, these procedures may be insufficient in some circumstances, e.g., in cases where the reading of the physical dosimeters is questioned, in cases of radiation accidents where the person(s) in question was not wearing a dosimeter, or in the event of a radiation emergency when an exposure above the dose limits is possible. The desirability of being able to assess radiation dose on the basis of radio-biological effects has prompted the Dosimetric Research Branch to investigate the suitability of biological devices and techniques that could be used for this purpose. Current biological dosimetry concepts suggest that there does not appear to be any bio-indicator that could reliably measure the very low doses that are routinely measured by the physical devices presently in use. Nonetheless, bio-indicators may be useful in providing valuable supplementary information in cases of unusual radiation exposures, such as when the estimated body doses are doubtful because of lack of proper physical measurements, or in cases where available results need to be confirmed for medical treatment plannings. This report evaluates the present state of biological dosimetry and, in particular, assesses the efficiency and limits of individual indicators. This has led to the recommendation of a few promising research areas that may result in the development of appropriate biological dosimeters for operational and emergency needs at Chalk River

  15. Process attributes in bio-ontologies

    2012-08-01

    Full Text Available Abstract Background Biomedical processes can provide essential information about the (mal- functioning of an organism and are thus frequently represented in biomedical terminologies and ontologies, including the GO Biological Process branch. These processes often need to be described and categorised in terms of their attributes, such as rates or regularities. The adequate representation of such process attributes has been a contentious issue in bio-ontologies recently; and domain ontologies have correspondingly developed ad hoc workarounds that compromise interoperability and logical consistency. Results We present a design pattern for the representation of process attributes that is compatible with upper ontology frameworks such as BFO and BioTop. Our solution rests on two key tenets: firstly, that many of the sorts of process attributes which are biomedically interesting can be characterised by the ways that repeated parts of such processes constitute, in combination, an overall process; secondly, that entities for which a full logical definition can be assigned do not need to be treated as primitive within a formal ontology framework. We apply this approach to the challenge of modelling and automatically classifying examples of normal and abnormal rates and patterns of heart beating processes, and discuss the expressivity required in the underlying ontology representation language. We provide full definitions for process attributes at increasing levels of domain complexity. Conclusions We show that a logical definition of process attributes is feasible, though limited by the expressivity of DL languages so that the creation of primitives is still necessary. This finding may endorse current formal upper-ontology frameworks as a way of ensuring consistency, interoperability and clarity.

  16. Heterogeneous Deformable Modeling of Bio-Tissues and Haptic Force Rendering for Bio-Object Modeling

    Science.gov (United States)

    Lin, Shiyong; Lee, Yuan-Shin; Narayan, Roger J.

    This paper presents a novel technique for modeling soft biological tissues as well as the development of an innovative interface for bio-manufacturing and medical applications. Heterogeneous deformable models may be used to represent the actual internal structures of deformable biological objects, which possess multiple components and nonuniform material properties. Both heterogeneous deformable object modeling and accurate haptic rendering can greatly enhance the realism and fidelity of virtual reality environments. In this paper, a tri-ray node snapping algorithm is proposed to generate a volumetric heterogeneous deformable model from a set of object interface surfaces between different materials. A constrained local static integration method is presented for simulating deformation and accurate force feedback based on the material properties of a heterogeneous structure. Biological soft tissue modeling is used as an example to demonstrate the proposed techniques. By integrating the heterogeneous deformable model into a virtual environment, users can both observe different materials inside a deformable object as well as interact with it by touching the deformable object using a haptic device. The presented techniques can be used for surgical simulation, bio-product design, bio-manufacturing, and medical applications.

    The exponential increase of genomic data brought by the advent of the next or the third generation sequencing (NGS) technologies and the dramatic drop in sequencing cost have driven biological and medical sciences to data-driven sciences. This revolutionary paradigm shift comes with challenges in terms of data transfer, storage, computation, and analysis of big bio/medical data. Cloud computing is a service model sharing a pool of configurable resources, which is a suitable workbench to address these challenges. From the medical or biological perspective, providing computing power and storage is the most attractive feature of cloud computing in handling the ever increasing biological data. As data increases in size, many research organizations start to experience the lack of computing power, which becomes a major hurdle in achieving research goals. In this paper, we review the features of publically available bio and health cloud systems in terms of graphical user interface, external data integration, security and extensibility of features. We then discuss about issues and limitations of current cloud systems and conclude with suggestion of a biological cloud environment concept, which can be defined as a total workbench environment assembling computational tools and databases for analyzing bio/medical big data in particular application domains.

    2012-11-01

    A great many living beings, such as aquatics and arthropods, are equipped with highly sensitive flow sensors to help them survive in challenging environments. These sensors are excellent sources of inspiration for developing application-driven artificial flow sensors with high sensitivity and performance. This paper reviews the bio-inspirations on flow sensing in nature and the bio-mimicking efforts to emulate such sensing mechanisms in recent years. The natural flow sensing systems in aquatics and arthropods are reviewed to highlight inspirations at multiple levels such as morphology, sensing mechanism and information processing. Biomimetic hair flow sensors based on different sensing mechanisms and fabrication technologies are also reviewed to capture the recent accomplishments and to point out areas where further progress is necessary. Biomimetic flow sensors are still in their early stages. Further efforts are required to unveil the sensing mechanisms in the natural biological systems and to achieve multi-level bio-mimicking of the natural system to develop their artificial counterparts.

    The Biological General Repository for Interaction Datasets (BioGRID: http://thebiogrid.org) is an open access database that houses genetic and protein interactions curated from the primary biomedical literature for all major model organism species and humans. As of September 2014, the BioGRID contains 749,912 interactions as drawn from 43,149 publications that represent 30 model organisms. This interaction count represents a 50% increase compared to our previous 2013 BioGRID update. BioGRID data are freely distributed through partner model organism databases and meta-databases and are directly downloadable in a variety of formats. In addition to general curation of the published literature for the major model species, BioGRID undertakes themed curation projects in areas of particular relevance for biomedical sciences, such as the ubiquitin-proteasome system and various human disease-associated interaction networks. BioGRID curation is coordinated through an Interaction Management System (IMS) that facilitates the compilation interaction records through structured evidence codes, phenotype ontologies, and gene annotation. The BioGRID architecture has been improved in order to support a broader range of interaction and post-translational modification types, to allow the representation of more complex multi-gene/protein interactions, to account for cellular phenotypes through structured ontologies, to expedite curation through semi-automated text-mining approaches, and to enhance curation quality control.

    Highlights: • Produced bio-fuels (bio-oil and bio-char) from some animal fatty wastes. • Investigated the effects of main parameters on pyrolysis products distribution. • Determined the suitable conditions for the production of the maximum of bio-oil. • Characterized bio-oils and bio-chars obtained from several animal fatty wastes. - Abstract: Several animal (lamb, poultry and swine) fatty wastes were pyrolyzed under nitrogen, in a laboratory scale fixed-bed reactor and the main products (liquid bio-oil, solid bio-char and syngas) were obtained. The purpose of this study is to produce and characterize bio-oil and bio-char obtained from pyrolysis of animal fatty wastes. The maximum production of bio-oil was achieved at a pyrolysis temperature of 500 °C and a heating rate of 5 °C/min. The chemical (GC–MS analyses) and spectroscopic analyses (FTIR analyses) of bio-oil showed that it is a complex mixture consisting of different classes of organic compounds, i.e., hydrocarbons (alkanes, alkenes, cyclic compounds…etc.), carboxylic acids, aldehydes, ketones, esters,…etc. According to fuel properties, produced bio-oils showed good properties, suitable for its use as an engine fuel or as a potential source for synthetic fuels and chemical feedstock. Obtained bio-chars had low carbon content and high ash content which make them unattractive for as renewable source energy.

    The purpose of this study was to assemble and disseminate knowledge about bio-oils and other bio fuels which are used for heat- and power generation or liquid bio fuels/oils that may become interesting in the future. One aim of this study was to give an updated picture of the Swedish market for bio-oils and to provide an overview of practical experience on the usage of bio-oils in the Swedish heat and power industry. In order to show a green profile, bio-oils can be used in the heat and power generation. However, not all bio-oils can be viewed as climate friendly. Some production of bio-oils may actually - if a lifecycle perspective is considered - lead to increased emissions of greenhouse gases, and there are also ethical issues that need to be considered. The data collection was carried out in three different fields. The objective of the first part was to create an overview of the Swedish market for liquid bio fuels/oils for heat and power production. The second part of the study aimed to clarify the issues surrounding environmental and ethical issues associated with the use of different bio-oils. A selection of oil crops for a closer study was made based on production volume (soybean, palm oil and rapeseed) and expected future potential (jatropha). This part of the study was based on a literature review. In the third part of the study technical and practical experiences from using bio-oils in heat and power production were studied. The interviews made with purchasing managers in the second part gave valuable information on which utilities would be the most interesting to interview for the study of technical and practical experiences, where interviews were carried out with persons familiar with the daily operation of the plant. The use of liquid bio fuels was about 4.3 % of total fuel use in Swedish district heating production in 2007 (1.2 % pine oil and 3.0 % other bio-oil). In other words, it is mainly bio-oils that have been used and not other types of liquid

    Studies were conducted on actuator function in bio materials, cells, structures, and living organisms, and on structuring a biological molecule machine. In the study on soft biological structures, biological compatibility of artificial glass bodies using ultra-polymeric PVA was found very high, raising expectation on feasibility of their practical use. Three-dimensional structure of glass bodies was made clear for the first time in the world. As a result of separating and purifying cells from a liver for the first time in the world, it was indicated that excellent proliferation performance and differentiation into cells are shown. With regard to hydroxyapatite in hard biological structure such as bones and teeth, single crystals were synthesized, and growth rate on the surface C was measured successfully. For molecular motors, studies are being performed on functions of twin-head structure in biological protein enzyme. In molecule structuring, studies were conducted on preparation of a hydrogenase LB membrane as an electric-hydrogen energy conversion element, and structuring of protein molecular structure using gene recombination. 69 refs., 37 figs., 8 tabs.

    We performed molecular dynamics simulations on the amorphous phase of two bio-based polymers, poly (butylene furanamide) and poly (hexamethylene furanamide). Simulations of corresponding petroleum-based polymers, nylon 4, 6 and nylon 6, 6, were also performed. Glass transition temperatures estimated from a series of simulations were in good agreement with experimental measurements. Stress-strain relationships under uniaxial deformation were also analyzed. Bio-based polymers show higher glass transition temperatures and comparable yield points despite having overall weaker hydrogen bonds compared with their counterparts nylons. This result suggests that the furan ring plays an important role in the thermodynamic and mechanical properties of bio-based polymers.

    Bio-oils from pyrolysis of as received sunflower seed hulls (SSH), hulls previously washed with acid (SSHA) and hulls submitted to a mushroom enzymatic attack (BSSH) were analyzed. The concentration of lignin, hemicellulose and cellulose varied with the pre-treatment. The liquid corresponding to SSH presented a relatively high concentration of acetic acid and a high instability to storage. The bio-oil from SSHA showed a high concentration of furfural and an appreciable amount of levoglucosenone. Lignin was degraded upon enzymatic activity, for this reason BSSH led to the highest yield of bio-oil, with relative high concentration of acetic acid and stability to storage.

When the sludge bulking appeared, the removal efficiency of COD in membrane bio-reactor increased slightly through the function of filamentous bacteria. However, the negative effects of the higher net water-head differential pressures, the high block rate of membrane pore and the great quantity of filamentous bacteria at the external surface presented at the same time. Thus, plenty of methods should be performed to control sludge bulking once it happened in membrane bio-reactor.

    Full Text Available Nitrogen fixing, phosphate solubilizing and potash mobilizing bacterial strains were isolated from rhizosphere soil of agricultural land, the isolated bacterial strains were further characterized by a series of biochemical reactions and identified as genus Azotobacter, Bacillus and Pseudomonas respectively. A technology for their mass multiplication and their bio-formulation has been developed. Fly-ash was used as carrier materials for bio-formulation development of bio-fertilizer strains. Shelf-life studies of the bio-formulations were carried out during storage period. The selected isolates were found to be potent nitrogen fixer, phosphate solubilizers showing clear halo zone around their colonies and potash mobilizer showing mobilization of potassium on respective medium. A general decline in cfu count was noticed in fly-ash based bio-formulations. All the bio-formulations however, retained more than 108 cfu/g viable propagules up to 270 days. The present studies were shown encouraging results in respect to fly-ash as carrier materials for bio-fertilizer strains which are comparable to other commercially available carrier materials.

    Recycling waste materials produced in our daily life is considered as an additional resource of a wide range of materials and it conserves the environment. Used engine oil and used cooking oil are two oils disposed off in large quantities as a by-product of our daily life. This study aims at providing white bio oil, bio petroleum diesel and heavy fuel from the disposed oils. Toxic organic materials suspected to be present in the used engine oil were separated using vacuum column chromatography to reduce the time needed for the separation process and to avoid solvent usage. The compounds separated were detected by gas chromatography-mass spectrometry (GC-MS) and found to contain toxic aromatic carboxylic acids. Used cooking oils (thermally cracked from usage) were collected and separated by vacuum column chromatography. White bio oil produced was examined by GC-MS. The white bio oil consists of non-toxic hydrocarbons and is found to be a good alternative to white mineral oil which is significantly used in food industry, cosmetics and drugs with the risk of containing polycyclic aromatic compounds which are carcinogenic and toxic. Different portions of the used cooking oil and used engine were mixed to produce several blends for use as heavy oil fuels. White bio oil was used to produce bio petroleum diesel by blending it with petroleum diesel and kerosene. The bio petroleum diesel produced passed the PETRONAS flash point and viscosity specification test. The heat of combustion of the two blends of heavy fuel produced was measured and one of the blends was burned to demonstrate its burning ability. Higher heat of combustion was obtained from the blend containing greater proportion of used engine oil. This study has provided a successful recycled alternative for white bio oil, bio petroleum fuel and diesel which can be an energy source.

  20. BioMEMS for mitochondria medicine

    Science.gov (United States)

    Padmaraj, Divya

    A BioMEMS device to study cell-mitochondrial physiological functionalities was developed. The pathogenesis of many diseases including obesity, diabetes and heart failure as well as aging has been linked to functional defects of mitochondria. The synthesis of Adenosine Tri Phosphate (ATP) is determined by the electrical potential across the inner mitochondrial membrane and by the pH difference due to proton flux across it. Therefore, electrical characterization by E-fields with complementary chemical testing was used here. The BioMEMS device was fabricated as an SU-8 based microfluidic system with gold electrodes on SiO2/Si wafers for electromagnetic interrogation. Ion Sensitive Field Effect Transistors (ISFETs) were incorporated for proton studies important in the electron transport chain, together with monitoring Na+, K+ and Ca++ ions for ion channel studies. ISFETs are chemically sensitive Metal Oxide Semiconductor Field Effect Transistor (MOSFET) devices and their threshold voltage is directly proportional to the electrolytic H+ ion variation. These ISFETs (sensitivity ˜55 mV/pH for H+) were further realized as specific ion sensitive Chemical Field Effect Transistors (CHEMFETs) by depositing a specific ion sensitive membrane on the gate. Electrodes for dielectric spectroscopy studies of mitochondria were designed as 2- and 4-probe structures for optimized operation over a wide frequency range. In addition, to limit polarization effects, a 4-electrode set-up with unique meshed pickup electrodes (7.5x7.5 mum2 loops with 4 mum wires) was fabricated. Sensitivity of impedance spectroscopy to membrane potential changes was confirmed by studying the influence of uncouplers and glucose on mitochondria. An electrical model was developed for the mitochondrial sample, and its frequency response correlated with impedance spectroscopy experiments of sarcolemmal mitochondria. Using the mesh electrode structure, we obtained a reduction of 83.28% in impedance at 200 Hz. COMSOL

    2014-03-01

    An optical closure study on bio-optical relationships was carried out using radiative transfer model matrix operator method developed by Freie Universität Berlin. As a case study, the optical closure of bio-optical relationships empirically parameterized with in situ data for the East China Sea was examined. Remote-sensing reflectance ( R rs) was computed from the inherent optical properties predicted by these biooptical relationships and compared with published in situ data. It was found that the simulated R rs was overestimated for turbid water. To achieve optical closure, bio-optical relationships for absorption and scattering coefficients for suspended particulate matter were adjusted. Furthermore, the results show that the Fournier and Forand phase functions obtained from the adjusted relationships perform better than the Petzold phase function. Therefore, before bio-optical relationships are used for a local sea area, the optical closure should be examined.

    International Nuclear Information System (INIS)

    The European energy policy has defined clear objectives to reduce the high dependency on fossil petroleum imports, and to increase the security of sustainable energy supply for the transport sector. Moreover, the European environmental policy is requesting clean fuels that reduce environmental risks. Liquid Bio fuels (vegetable oils and bio ethanol) appear to be in a good position to contribute to achieve these goals expressed by the established objective of European Union to reach for bio fuels a market share of 5% of motor vehicle consumption. This work presents the current state and perspectives of the production and utilisation of liquid fuels from agricultural sources by reviewing agricultural feedstocks for energy sector, conversion technologies and different ways to use bio fuels. Environmental and economical aspects are also briefly analysed. (Author) 10 refs

  10. Past, Present, and Future Production of Bio-oil

    Energy Technology Data Exchange (ETDEWEB)

    Steele, Philip; Yu, Fei; Gajjela, Sanjeev

    2009-04-01

    Bio-oil is a liquid product produced by fast pyrol-ysis of biomass. The fast pyrolysis is performed by heating the biomass rapidly (2 sec) at temperatures ranging from 350 to 650 oC. The vapors produced by this rapid heating are then condensed to produce a dark brown water-based emulsion composed of frag-ments of the original hemicellulose, cellulose and lignin molecules contained in the biomass. Yields range from 60 to 75% based on the feedstock type and the pyrolysis reactor employed. The bio-oil pro-duced by this process has a number of negative prop-erties that are produced mainly by the high oxygen content (40 to 50%) contributed by that contained in water (25 to 30% of total mass) and oxygenated compounds. Each bio-oil contains hundreds of chemi-cal compounds. The chemical composition of bio-oil renders it a very recalcitrant chemical compound. To date, the difficulties in utilizing bio-oil have limited its commercial development to the production of liq-uid smoke as food flavoring. Practitioners have at-tempted to utilize raw bio-oil as a fuel; they have also applied many techniques to upgrade bio-oil to a fuel. Attempts to utilize raw bio-oil as a combustion engine fuel have resulted in engine or turbine dam-age; however, Stirling engines have been shown to successfully combust raw bio-oil without damage. Utilization of raw bio-oil as a boiler fuel has met with more success and an ASTM standard has recently been released describing bio-oil characteristics in relation to assigned fuel grades. However, commercialization has been slow to follow and no reports of distribution of these bio-oil boiler fuels have been reported. Co-feeding raw bio-oil with coal has been successfully performed but no current power generation facilities are following this practice. Upgrading of bio-oils to hydrocarbons via hydroprocessing is being performed by several organizations. Currently, limited catalyst life is the obstacle to commercialization of this tech-nology.

    In the last decades, bio-derived natural materials, such as vegetable oils, polysaccharides and biomass represent a rich source of hydroxyl precursors for the synthesis of polyols which can be potentially used to synthesize "greener" polyurethane foams. Herein a bio-based precursor (obtained from succinic acid) was used as a partial replacement of conventional polyol to synthesize PU foams. A mixture of conventional and bio-based polyol in presence of catalysts, silicone surfactant and diphenylmethane di-isocyanate (MDI) was expanded in a mold and cured for two hours at room temperature. Experimental results highlighted the suitability of this bio-precursor to be used in the production of flexible PU foams. Furthermore the chemo-physical characterization of the resulting foams show an interesting improvement in thermal stability and elastic modulus with respect to the PU foams produced with conventional polyol.

    Highlights: • Swine carcasses can be converted to bio-oil by alkaline hydrothermal liquefaction. • It seems that the use of the bio-oil for heat or CHP is technically suitable. • Some valuable chemicals were found in the bio-oils. • The bio-oil and the solid residue constituted an energy efficiency of 93.63% for the feedstock. • The solid residue can be used as a soil amendment, to sequester C and for preparing activated carbon. - Abstract: It is imperative that swine carcasses are disposed of safely, practically and economically. Alkaline hydrothermal liquefaction of swine carcasses to bio-oil was performed. Firstly, the effects of temperature, reaction time and pH value on the yield of each liquefaction product were determined. Secondly, liquefaction products, including bio-oil and solid residue, were characterized. Finally, the energy recovery ratio (ERR), which was defined as the energy of the resultant products compared to the energy input of the material, was investigated. Our experiment shows that reaction time had certain influence on the yield of liquefaction products, but temperature and pH value had bigger influence on the yield of liquefaction products. Yields of 62.2 wt% bio-oil, having a high heating value of 32.35 MJ/kg and a viscosity of 305cp, and 22 wt% solid residue were realized at a liquefaction temperature of 250 °C, a reaction time of 60 min and a pH value of 9.0. The bio-oil contained up to hundreds of different chemical components that may be classified according to functional groups. Typical compound classes in the bio-oil were hydrocarbons, organic acids, esters, ketones and heterocyclics. The energy recovery ratio (ERR) reached 93.63%. The bio-oil is expected to contribute to fossil fuel replacement in stationary applications, including boilers and furnaces, and upgrading processes for the bio-oil may be used to obtain liquid transport fuels.

    Methyl, ethyl, 2-propyl and butyl esters were prepared from canola and linseed oils through transesterification using KOH and/ or sodium alkoxides as catalysts. In addition, methyl and ethyl esters were prepared from rapeseed and sunflower oils using the same catalysts. Chemical composition of the esters was determined by HPLC for the class of lipids and by GC for fatty acid compositions. The bio-diesel esters were characterized for their physical and fuel properties including density, viscosity, iodine value, acid value, cloud point, pure point, gross heat of combustion and volatility. Methyl and ethyl esters prepared from a particular vegetable oil had similar viscosities, cloud points and pour points, whereas methyl, ethyl, 2-propyl and butyl esters derived from a particular vegetable oil had similar gross heating values. However, their densities, which were 2 7% higher than those of diesel fuels, statistically decreased in the order of methyl approximately 2-propyl > ethyl > butyl esters. Butyl esters showed reduced cloud points (-6 degrees C to -10 degrees C) and pour points (-13 degrees C to -16 degrees C) similar to those of summer diesel fuel having cloud and pour points of -8 degrees C and -15 degrees C, respectively. The viscosities of bio-diesels (3.3-7.6 x 10(-4) Pa s at 40 degrees C) were much less than those of pure oils (22.4-45.1 x 10(-4) Pa s at 40 degrees C) and were twice those of summer and winter diesel fuels (3.50 and 1.72 x 10(-4) Pa s at 40 degrees C), and their gross heat contents of approximately 40 MJ/kg were 11% less than those of diesel fuels (approximately 45 MJ/kg). For different esters from the same vegetable oil, methyl esters were the most volatile, and the volatility decreased as the alkyl group grew bulkier. However, the bio-diesels were considerably less volatile than the conventional diesel fuels. PMID:11554602

  13. Bio-Mimetic Sensors Based on Molecularly Imprinted Membranes

    2014-07-01

    Full Text Available An important challenge for scientific research is the production of artificial systems able to mimic the recognition mechanisms occurring at the molecular level in living systems. A valid contribution in this direction resulted from the development of molecular imprinting. By means of this technology, selective molecular recognition sites are introduced in a polymer, thus conferring it bio-mimetic properties. The potential applications of these systems include affinity separations, medical diagnostics, drug delivery, catalysis, etc. Recently, bio-sensing systems using molecularly imprinted membranes, a special form of imprinted polymers, have received the attention of scientists in various fields. In these systems imprinted membranes are used as bio-mimetic recognition elements which are integrated with a transducer component. The direct and rapid determination of an interaction between the recognition element and the target analyte (template was an encouraging factor for the development of such systems as alternatives to traditional bio-assay methods. Due to their high stability, sensitivity and specificity, bio-mimetic sensors-based membranes are used for environmental, food, and clinical uses. This review deals with the development of molecularly imprinted polymers and their different preparation methods. Referring to the last decades, the application of these membranes as bio-mimetic sensor devices will be also reported.

    Full Text Available Pyrolysis of palm kernel shell in a fixed-bed reactor was studied in this paper. The objectives were to investigate the effect of pyrolysis temperature and particle size on the products yield and to characterize the bio-oil product. In order to get the optimum pyrolysis parameters on bio-oil yield, temperatures of 350, 400, 450, 500 and 550 °C and particle sizes of 212–300 µm, 300–600 µm, 600µm–1.18 mm and 1.18–2.36 mm under a heating rate of 50 °C min-1 were investigated. The maximum bio-oil yield was 38.40% at 450 °C with a heating rate of 50 °C min-1 and a nitrogen sweep gas flow rate of 50 ml min-1. The bio-oil products were analysed by Fourier transform infra-red spectroscopy (FTIR and gas chromatography–mass spectroscopy (GCMS. The FTIR analysis showed that the bio-oil was dominated by oxygenated species. The phenol, phenol, 2-methoxy- and furfural that were identified by GCMS analysis are highly suitable for extraction from the bio-oil as value-added chemicals. The highly oxygenated oils need to be upgraded in order to be used in other applications such as transportation fuels.

    2008-07-15

    Maize stalk and bio-briquette binder made from it were studied comparatively by FTIR and the microstructure of bio-briquette was observed and analyzed by microscopy. It was found that a large amount of unreacted biomass fibers exist in the binder. These form a multi-level network structure inside the bio-briquette and could make fine coal particles connect together. The multi-level network structure would be still present after the bio-briquettes are immersed in water for 24 hours. On the other hand, stalk materials could be partly degraded after treatment and, with other liquid ingredients in the binder, the degradation products could form a viscous fluid which would work as a bonding ingredient inside the bio-briquette and could improve the waterproofing ability of the binder after solidification. Therefore, the multi-level network structure of the biomaterial and the presence of viscous fluid are very important to the shaping and the improvement of the waterproofing ability of bio-briquettes. 11 refs., 3 figs.

    2016-01-01

    A- and B-type lamins support the nuclear envelope, contribute to heterochromatin organization, and regulate a myriad of nuclear processes. The mechanisms by which lamins function in different cell types and the mechanisms by which lamin mutations cause over a dozen human diseases (laminopathies) remain unclear. The identification of proteins associated with lamins is likely to provide fundamental insight into these mechanisms. BioID (proximity-dependent biotin identification) is a unique and powerful method for identifying protein-protein and proximity-based interactions in living cells. BioID utilizes a mutant biotin ligase from bacteria that is fused to a protein of interest (bait). When expressed in living cells and stimulated with excess biotin, this BioID-fusion protein promiscuously biotinylates directly interacting and vicinal endogenous proteins. Following biotin-affinity capture, the biotinylated proteins can be identified using mass spectrometry. BioID thus enables screening for physiologically relevant protein associations that occur over time in living cells. BioID is applicable to insoluble proteins such as lamins that are often refractory to study by other methods and can identify weak and/or transient interactions. We discuss the use of BioID to elucidate novel lamin-interacting proteins and its applications in a broad range of biological systems, and provide detailed protocols to guide new applications.

    Screened atrazine-mineralizing bacterium-Pseudomonas W4 was embedded inside an improved PVAH3BO3 embedment matrix to make bio-beads to degrade atrazine. The atrazine degradation characteristics were studied. The preparation procedure of bio-beads was as follows: (1) preparing a mixture of 100, 12.5, 10, 1.5 and 1 g/L PVA, bentonite(Ca), activated carbon powder, sodium alginate and centrifuged Pseudomonas W4 bacterium, respectively; (2) the mixture was dropped into a gently stirred cross linker solution(pH=6.7) and cured at 10 ℃ for 24 h.The optimal atrazine degradation conditions by bio-beads were as follows: pH=7, the auxiliary carbon source was glucose, and the concentration of glucose was greater than 325 mg/L. The bio-beads demonstrated stronger tolerance ability than the free microorganism to the increase of PCBs, hydrogen ion and hydroxide ion. SEM images show the uniform distribution of the microorganism inside bio-beads and the porous cross-linked structure of bio-beads which provides excellent mass transfer capacity.

    2016-03-01

    Full Text Available This study analyzed uniaxial compression strength over time by preparing a homogel specimen from a bio grouting material, a cement-like form produced by environment-friendly microbial reactions. Among chemical grouting methods, the most commonly used method is the Labile Waterglass method. In this study, the homogel uniaxial compressive strength of Labile Waterglass (LW injection material and that of bio grouting material were measured and analyzed. In order to perform the experiment, a total of 10 types of grouting mixing ratios were prepared by a combination of different materials such as Ordinary Portland Cement, Micro Cement, Bio Grouting Material and Sodium Silicate. They were cured in the air, and their homogel uniaxial compression strengths were measured on days 1, 3, 7 and 28 Based on the test results, it was confirmed that the uniaxial strength of the specimen made with Bio Grouting Material, Ordinary Portland Cement and Micro Cement was increased by more than 30% than that of the specimen only used with Ordinary Portland Cement, as a result of hydrogen-released heat reaction between calcium carbonate, the main ingredient of the bio grouting material, and calcium silicate in the cement. This indicates that the use of 30% bio-grouting material instead of cement in the grouting can be a reasonable mixing ratio to save the use of cement, leading to reduction in CO2 emission.

    Full Text Available BioCCS is a technology gaining support as a possible emissions reduction policy option to address climate change. The process entails the capture, transport and storage of carbon dioxide produced during energy production from biomass. Globally, the most optimistic energy efficiency scenarios cannot avoid an average temperature increase of +2 °C without bioCCS. Although very much at the commencement stage, bioCCS demonstration projects can provide opportunity to garner knowledge, achieve consensus and build support around the technology’s properties. Yet many challenges face the bioCCS industry, including no guarantee biomass will always be from sustainable sources or potentially result in carbon stock losses. The operating environment also has no or limited policies, regulations and legal frameworks, and risk and safety concerns abound. Some state the key problem for bioCCS is cultural, lacking in a ‘community of support’, awareness and credibility amongst its own key stakeholders and the wider public. Therefore, the industry can benefit from the growing social science literature, drawing upon other energy and resource based industries with regard to social choice for future energy options. To this end, the following scoping review was conducted in order to ascertain gaps in existing public perception and acceptance research focusing on bioCCS.

  1. Bio-Based Polymers with Potential for Biodegradability

    2016-07-01

    Full Text Available A variety of renewable starting materials, such as sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, and proteins, have so far been investigated for the preparation of bio-based polymers. Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry due to their easy availability, low toxicity, and relative low cost. Another bio-based plastic of great interest is poly(lactic acid (PLA, widely used in multiple commercial applications nowadays. There is an intrinsic expectation that bio-based polymers are also biodegradable, but in reality there is no guarantee that polymers prepared from biorenewable feedstock exhibit significant or relevant biodegradability. Biodegradability studies are therefore crucial in order to assess the long-term environmental impact of such materials. This review presents a brief overview of the different classes of bio-based polymers, with a strong focus on vegetable oil-derived resins and PLA. An entire section is dedicated to a discussion of the literature addressing the biodegradability of bio-based polymers.

  3. Environmental sustainability assessment of bio-ethanol production in Thailand

    International Nuclear Information System (INIS)

    Bio-ethanol is playing an important role in renewable energy for transport according to Thai government policy. This study aims to evaluate the energy efficiency and renewability of bio-ethanol system and identify the current significant environmental risks and availability of feedstocks in Thailand. Four of the seven existing ethanol plants contributing 53% of the total ethanol fuel production in Thailand have been assessed by the net energy balance method and Life Cycle Assessment (LCA). A renewability and net energy ratio portfolio has been used to indicate whether existing bio-ethanol production systems have net energy gain and could help reduce dependency on fossil energy. In addition, LCA has been conducted to identify and evaluate the environmental hotspots of 'cradle to gate' bio-ethanol production. The results show that there are significant differences of energy and environmental performance among the four existing production systems even for the same feedstock. The differences are dependent on many factors such as farming practices, feedstock transportion, fuel used in ethanol plants, operation practices and technology of ethanol conversion and waste management practices. Recommendations for improving the overall energy and environmental performance of the bio-ethanol system are suggested in order to direct the bio-ethanol industry in Thailand towards environmental sustainability.

    The objective of the BioForest project is to develop the science and technology of a series of integrated processing steps which economically convert mixed hardwood and softwood biomass and recycled fibers into commodity chemicals at an existing forest products complex which also produces wood and/or pulp and paper. The commodity products will be produced from the biomass carbohydrates using a novel biomass fractionation process, a modified ABE (Acetone- Butanol-Ethanol) fermentation process, and a novel continuous solvent recovery method from the fermentation liquid. The mixture of solvents produced by the modified ABE process consists of isopropanol, butanol and ethanol. The key technological barriers which have been accomplished in the Bioforest project are following: 1. Fundamental understanding of the kinetics of delignification, hemicellulose dissolution and cellulose degradation during SEW fractionation of softwood and hardwood 2. Optimization of SEW fractionation of softwood biomass with a total treatment time as short as 30 minutes 3. Simultaneous SEW fractionation of hardwood and softwood biomass 4. Production of a high concentration (> 100 g/L) hemicellulose monosugar solution from SEW spent fractionation liquor at a sugar yield larger than 85% by multistep conditioning 5. Construction of E.coli strain harboring isopropanol dehydrogenase gene capable of acetone conversion to isopropanol 6. Successful fermentation of the conditioned hemicellulose monosugar solution to ABE (Acetone, Butanol, Ethanol) solvents using advanced column technology (patent pending) or semi-solid pulp fermentations with the volumetric productivities of 5.5 and 13.5 g/L h respectively.

    Pacardo, Dennis Kien Balaong

    The biomimetic synthesis of Pd nanoparticles was presented using the Pd4 peptide, TSNAVHPTLRHL, isolated from combinatorial phage display library. Using this approach, nearly monodisperse and spherical Pd nanoparticles were generated with an average diameter of 1.9 +/- 0.4 nm. The peptide-based nanocatalyst were employed in the Stille coupling reaction under energy-efficient and environmentally friendly reaction conditions of aqueous solvent, room temperature and very low catalyst loading. To this end, the Pd nanocatalyst generated high turnover frequency (TOF) value and quantitative yields using ≥ 0.005 mol% Pd as well as catalytic activities with different aryl halides containing electron-withdrawing and electron-donating groups. The Pd4-capped Pd nanoparticles followed the atom-leaching mechanism and were found to be selective with respect to substrate identity. On the other hand, the naturally-occurring R5 peptide (SSKKSGSYSGSKGSKRRIL) was employed in the synthesis of biotemplated Pd nanomaterials which showed morphological changes as a function of Pd:peptide ratio. TOF analysis for hydrogenation of olefinic alcohols showed similar catalytic activity regardless of nanomorphology. Determination of catalytic properties of these bio-inspired nanomaterials are important as they serve as model system for alternative green catalyst with applications in industrially important transformations.

    The usage of biomass as a renewable source of energy is an important issue for a sustainable energy supply in Denmark. Due to pioneering work, Denmark has great experience in producing energy from biomass both in large scale CHP utilities as well as in small scale application such as domestic heating. This experience has been mainly focused in the usage of traditional domestic solid biomass fuels such as wood. However, the limited amounts available of these fuels and thereby following increasing prices have triggered the interest in using other sources of biomass. Rest and waste products from the agricultural industry is one examples of biomass which has a large potential to be used as a cheap biomass fuels. Projects of using these new types of biomass fuels are often hindered by insecurity whether this new biomass source can be applied as fuel or not. Thus in order to support usage of new sources of biomass a first step is to have knowledge on properties of the biomass fuel and be able to compare these to the known traditional fuels used. The BioLex was designed to provide this information about important properties of both traditional Danish as well as new more exotic solid biomass fuels in a database available to the public via the internet.

    In this thesis we studied the applications of colloidal nanocrystal quantum dots (QD) in bio-medical studies. We investigate the synthesis of QD and report a relatively simple method for synthesizing QD. To produce QDs that are more stable and have higher fluorescent quantum efficiency than those produced by other methods (typically CdSe/ZnS core/shell structures), we developed a CdSe/ZnSe/ZnS (core/shell/shell) nanocrystal complex, capped with the small molecule mercaptoacetic acid (MAA) for aqueous solubilization and low toxicity. These MAA-capped QDs can be used as the visualization aid for a multi-functional probe combining the functions of viruses and carbon nanotubes (CNT). A mild method of tagging virus through a polycationic solution, Polybrene, at 4°C is developed. This method can preserve most viral infectivity. The probes can be used to induce higher death rate in cells under near-infrared laser irradiation than in the cells without them, and thus, after additional improvements, may find applications in the study of cancer therapy. The optical properties of MAA-capped QDs are pH dependent. In particular, the fluorescence intensity increases with pH (pH between 4 and 10) of the environment. The results lead to a new venue to exploit QD as nano-scale sensors for localized physical and chemical properties in cells.

    Highlights: • We synthesized a magnetic bio-NCP with potential to be used against breast cancer. • The magnetic nanoparticles have an inverted spinel structure. • The coating with chitosan does not cause changes to the particle microstructure. • The hydration level of bio-NCP is crucial to the surface modification with apatite. • Bio-NCP with narrow size distribution and high magnetic response was obtained. -- Abstract: Breast cancer is a public health problem throughout the world. Moreover, breast cancer cells have a great affinity for hydroxyapatite, leading to a high occurrence of bone metastasis. In this work we developed a bio-nanocomposite (bio-NCP) in order to use such affinity in the diagnosis and treatment of breast cancer. The bio-NCP consists of magnetic nanoparticles of Mn and Zn ferrite inside a polymeric coating (chitosan) modified with nanocrystals of apatite. The materials were characterized with synchrotron X-ray Powder Diffraction (XPD), Time-of-Flight Neutron Powder Diffraction (NPD), Fourier Transformed Infra-red Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and magnetic measurement with a Physical Property Measurement System (PPMS). We obtained ferrite nanoparticles with a high inversion degree of the spinel structure regarding the Fe and Mn, but with all the Zn in the A site. The coating of such nanoparticles with chitosan had no notable effects to the ferrite microstructure. In addition, the polymeric surface can be easily modified with apatite nanocrystals since the hydration of the bio-NCP during synthesis can be controlled. The resulting bio-NCP presents a spherical shape with a narrow size distribution and high magnetic response at room temperature and is a very promising material for early diagnosis of breast cancer and its treatment.

    Bio-hybrid artificial organs are an attractive concept to restore organ function through precise biological cooperation with surrounding tissues in vivo. However, in bio-hybrid artificial organs, an artificial organ with fibrous connective tissues, including muscles, tendons and ligaments, has not been developed. Here, we have enveloped with embryonic dental follicle tissue around a HA-coated dental implant, and transplanted into the lower first molar region of a murine tooth-loss model. We successfully developed a novel fibrous connected tooth implant using a HA-coated dental implant and dental follicle stem cells as a bio-hybrid organ. This bio-hybrid implant restored physiological functions, including bone remodelling, regeneration of severe bone-defect and responsiveness to noxious stimuli, through regeneration with periodontal tissues, such as periodontal ligament and cementum. Thus, this study represents the potential for a next-generation bio-hybrid implant for tooth loss as a future bio-hybrid artificial organ replacement therapy.

    Full Text Available Bio-Diesel the word itself defines almost all the features of the Bio-Diesel literary. In the Era of this Global Warming where the people are making their living more and more comfortable and they are deteriorating the environment also. The uses of the automobiles with the conventional source of fuel leads to the production of the toxic gaseous substances like carbon monoxide, carbon dioxide, oxides of nitrogen, oxide of sulphur, hydro-carbons etc. The limitation comes with the rise in the price of the fuel as well as the produce of the green house gases as the exhaust gas. In the present study, a new method has been employed to produce Bio-Diesel in a homely basis. Theproduction of the Bio-Diesel is done by using Bio-Diesel processor. It requires the used vegetable oil, methanol and the lye with the accurate proportionate. Generally, emissions of regulated compounds changed linearly with the blend level. The objective is to detect any posit ive or negative effects depending on blend levels, because conventional diesel fuel and biodiesel can be blended in every ratio. The known positive and negative effects of biodiesel varied accordingly and investigate the effect of Catalytic Converter on emission performance with Bio- Diesel Blends.

    Full Text Available The principal photosynthetic pathways convert solar energy differently depending on the environmental conditions and the plant morphotype. Partitioning of energy storage within crops will vary according to environmental and seasonal conditions as well. Highest energy concentration is found in terpens like latex and, to a lesser extent, in lipids. Ideally, we want plant ingredients with high energy content easily amenable to ready-to-use bio-fuel. Generally, these crops are adapted to drier areas and tend to save on eco-volume space. Competition with food crops could be avoided by fetching energy from cheap agricultural by-products or waste products such as bagasse in the sugar cane. This would in fact mean that reducing power of agricultural residues should be extracted from the biomass through non-photosynthetic processes like animal ingestion or industrial bio-fermentation. Conversion and transformation efficiencies in the production chain are illustrated for some relevant crops in the light of the maximum power theorem.

    To increase the share of biomass for renewable energy in Europe conversion pathways which are economic, flexible in feedstock and energy efficient are needed. The BioBoost project concentrates on dry and wet residual biomass and wastes as feedstock for de-central conversion by fast pyrolysis, catalytic pyrolysis and hydrothermal carbonization to the intermediate energy carriers oil, coal or slurry. Based on straw the energy density increases from 2 to 20-30 GJ/m{sup 3}, enabling central GW scale gasification plants for bio-fuel production. A logistic model for feedstock supply and connection of de-central with central conversion is set up and validated allowing the determination of costs, the number and location of de-central and central sites. Techno/economic and environmental assessment of the value chain supports the optimization of products and processes. The utilization of energy carriers is investigated in existing and coming applications of heat and power production and synthetic fuels and chemicals. (orig.)

  14. The relation between Puelche wind and the occurrence of forest fires in Bio Bio region, Chile

    International Nuclear Information System (INIS)

    This paper presents a study of the relation between Puelche wind and forest fires in the Bio Bio Region, Chile. To establish a relationship between Puelche wind and forest fire generation, different data analysis methods and statistics test were applied. The relation between the total number of fires in the season and the days with Puelche wind were not statistically significant. When analyzing daily averages of fires produced with and without Puelche wind for each season, the highest daily fire occurrence values were found when there is Puelche wind, indicating that this event produces a strong effect on the daily occurrence of fires since these increased by 90% in comparison to the days without Puelche wind. The results of the difference between the number of fires with and without Puelche wind with respect to the average number of total fires indicate that the days with Puelche wind surpass both the total and the average values for days without Puelche wind, confirming the strong effect that a Puelche wind day has on forest fires. The greatest number of fires produced with Puelche wind occurs in the Province of Concepcion. This Province is the most affected by Puelche wind conditions despite having the smallest surface area for the region studied. Still, it is the most populous province of the region and has the greatest surface area with forests and plantations with respect to its size. Consequently, Puelche wind is a factor that increases the occurrence of forest fires and favors their propagation.

    Basic characteristics of the market for bioenergy (biomass, biogas and biofuels) in Hungary and consequences for business environment are summarized, based on a SWOT analysis. RES is the priority issue to which a lot of attention is paid both at governmental and private level; private investors should view RES as a new niche for their business activities. Standard approach based on a thoroughly done preparation of the project in terms of profitability and risk assessment is necessary in order to avoid potential financial losses due to changed market conditions or differences between assumptions and business reality. Some recommendations for entry on the Hungarian bio energy market are presented: (1) Generally, look for success stories in the Netherlands first and then look for places where such proved and time-tested technologies could be used in Hungary with respect to local specifics. In such way, you can find market niches where investment can be made or new products can be launched; (2) For retail selling it is appropriate to establish business contacts with existing dealers and associations and offer own products through their distribution network. This scheme has the advantage of low initial costs as well as risks involved; (3) In the case of large investments into equipment complexes using RES it seems more appropriate to refer directly either to municipal authorities on whose cadastre the investment should take place or to specialized consultancy agencies that can support the plan with additional information on legal requirements, national programmes supporting RES or available technology. Of course, direct collaboration with well-established local partner can be beneficial for both sides too; (4) If you want to receive up-to-date information on particular aspects of the biomass market in Hungary, you can refer to some governmental organisations associations referred in the key contact addresses.

    Objective: To study the effect of bio-derived bones, as substitutes of autogenous bone grafts and demineralized cadaver bones, on the attachment, spreading and proliferation of isolated osteoblasts. Methods: Osteoblasts were isolated from the calvaria of a fetal rabbit through sequential collagenase digestion. In the attachment study, the osteoblasts labeled with 3H-leucine were incubated with the bio-derived bone materials in sterile microcentrifugale tubes for 15, 90 and 180 minutes, and 24 hours, respectively. The attached cells were collected and the radioactivity was measured with liquid scintillation spectrometry. In the proliferation study, the osteoblasts were cultured with the bio-derived bone materials for 24 hours and 3H-thymidine was added during the last 2 hours of the incubation. The attached cells were collected and the radioactivity was measured with liquid scintillation spectrometry. Osteoblasts were seeded on the bone graft materials for 60 or 120 minutes, 24 or 48 hours, and 3 or 7 days, then the co-culture was processed for scanning electron microscopy to observe the interaction of osteoblasts and the bio-derived bone materials. Results: Osteoblasts attached to the bio-derived bone materials in a time-dependent manner. There were significantly (P<0.05) more attached cells after 180 minutes than after 15 and 90 minutes of incubations (P<0.05). Osteoblasts were proliferated in a large amount on the surface and in the materials. Osteoblasts seeded onto 100 mg bio-derived bones resulted in significantly (P<0.05) more measurable proliferation than those seeded onto 10 mg bones. Osteoblasts appeared round as they attached to the materials, then flattened and spread over with time passing. Conclusions: Bio-derived bones can provide a good environment for the attachment and proliferation of osteoblasts.

    Full Text Available Empty fruit bunches (EFB are one of the solid wastes produced by the palm oil industry, which is increasing rapidly. The aim of this paper is to analyse the viscosity of empty fruit bunch (EFB bio-oil that can be extracted from all solid waste EFB as a sample, and a few processes were executed. The samples underwent two processes, which were pre-treatment and pyrolysis. The pre-treatment involved three processes, namely, cutting, shredding and sieving, which were necessary in order to prepare EFB into a particle size suitable for the reactor. After that, the samples were fed into the feedback reactor as feedstock for the pyrolysis process to produce bio-oil. Once the bio-oil was produced, its viscosity was tested using the Brookfield Viscometer in two conditions: before and after the chemical reaction. The bio-oil was treated by adding 10 ml and 20 ml of acetone respectively through the chemical reaction. The viscosity test was carried out at different temperatures, which were 25°C, 30°C, 35°C, 40°C, 45°C and 50°C respectively. The observed viscosity of the EFB bio-oil varied and was higher as the temperature decreased. In addition, the viscosity of the EFB bio-oil was higher when it reacted chemically with the acetone added. Therefore, the results showed that the chemical reaction with acetone has the potential to increase the viscosity of EFB bio-oil.

  19. BioEnergy Feasibility in South Africa

    The BioEnergy Atlas for South Africa is the result of a project funded by the South African Department of Science and Technology, and executed by SAEON/ NRF with the assistance of a number of collaborators in academia, research institutions, and government. Now nearing completion, the Atlas provides an important input to policy and decision support in the country, significantly strengthens the availability of information resources on the topic, and provides a platform whereby current and future contributions on the subject can be managed, preserved, and disseminated. Bioenergy assessments have been characterized in the past by poor availability and quality of data, an over-emphasis on potentials and availability studies instead of feasibility assessment, and lack of comprehensive evaluation in competition with alternatives - both in respect of competing bioenergy resources and other renewable and non-renewable options. The BioEnergy Atlas in its current edition addresses some of these deficiencies, and identifies specific areas of interest where future research and effort can be directed. One can qualify the potentials and feasible options for BioEnergy exploitation in South Africa as follows: (1) Availability is not a fixed quantum. Availability of biomass and resulting energy products are sensitive to both the exclusionary measures one applies (food security, environmental, social and economic impacts) and the price at which final products will be competitive. (2) Availability is low. Even without allowing for feasibility and final product costs, the availability of biomass is low: biomass productivity in South Africa is not high by global standards due to rainfall constraints, and most arable land is used productively for food and agribusiness-related activities. This constrains the feasibility of purposely cultivated bioenergy crops. (3) Waste streams are important. There are significant waste streams from domestic solid waste and sewage, some agricultural

    The degradation properties and combustion performance of raw bio-oil, aged bio-oil, and bio-oil from torrefied wood were investigated through thermogravimetric analysis. A three-stage process was observed for the degradation of bio-oils, including devolatilization of the aqueous fraction and light compounds, transition of the heavy faction to solid, and combustion of carbonaceous residues. Pyrolysis kinetics parameters were calculated via the reaction order model and 3D-diffusion model, and combustion indexes were used to qualitatively evaluate the thermal profiles of tested bio-oils for comparison with commercial oils such as fuel oils. It was found that aged bio-oil was more thermally instable and produced more combustion-detrimental carbonaceous solid. Raw bio-oil and bio-oil from torrefied wood had comparable combustion performance to fuel oils. It was considered that bio-oil has a potential to be mixed with or totally replace the fuel oils in boilers.
