    Full Text Available In this paper, a qualitative energy flow analysis in Bangladesh agriculture has been made for a period from 1980-81 to 2000-01 to evaluate the impact of energy input to produce output. Human & animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. Energy values are calculated by multiplying respective quantity by their respective energy equivalents with the use of relevant conversion factors. Energy flow studied based on some energy dependent indicators: energy input per ha, energy output per ha, energy output to input ratio, mechanization index, energy input to generate per unit GDP output as well as per unit output in energy term and solar energy conversion efficiency. During the study period, energy input and output to Bangladesh agriculture were increased from 6.4 to 17.32 GJ ha-1 and 72.22 to 130.05 GJ ha-1, respectively. It is found that energetic efficiency (energy output to input ratio was declined from 11.28% to 8.1%, which indicates that the energy input increased faster than energy output. It is expected that sustainable energy flow in Bangladesh agriculture can be ascertained by this study.

  3. Energy poverty in rural Bangladesh

    International Nuclear Information System (INIS)

    Energy poverty is a well-established concept among energy and development specialists. International development organizations frequently cite energy-poverty alleviation as a necessary condition to reduce income poverty. Several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting. This paper uses a demand-based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income. At or below this threshold point, households consume a bare minimum level of energy and should be considered energy poor. This approach was applied using cross-sectional data from a comprehensive 2004 household survey representative of rural Bangladesh. The findings suggest that some 58 percent of rural households in Bangladesh are energy poor, versus 45 percent that are income poor. The findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty. - Research Highlights: →We estimate energy poverty for rural Bangladesh adopting a demand-based approach. →Findings suggest that energy poverty does not necessarily follow the same pattern as income poverty. →Access to modern energy and efficient use of traditional energy help alleviate energy poverty. →Energy poverty indicator can help track the effectiveness of a wide range of energy policies.

    Full Text Available Bangladesh is encountering difficulties in supplying energy to maintain its economic growth. Government of Bangladesh is looking for renewable energy sources to meet up the total power demand in this country. The present study aims to assess wind energy potential in Bangladesh as a sustainable solution to overcome the energy crisis. Wind speed at six coastal zones Patenga, Cox’s Bazar, Teknaf, Char Fassion, Kuakata and Kutubdia at Bay of Bengal of Bangladesh have been analyzed. A near shore wind farm has been considered at these locations having a coastal line of 574 km. The turbines are spaced 7D apart in the prevailing wind direction, and 3D apart in the perpendicular direction, where D is rotor diameter. This near shore wind farm with an array of 5104 horizontal axis wind turbines with hub height of 100 m and rotor diameter of 75 m with a wind speed of 7 m/sec is capable to generate 1855.25 MW of electrical power. This can mitigate 55.93 per cent of energy shortage in 2016. By developing renewable energy sources it is possible to compensate 11.25 per cent of total power demand by 2020.

  6. Non-power application of nuclear energy: Bangladesh perspective

    International Nuclear Information System (INIS)

    Radiation technology offers a very wide scope for utilisation and commercial exploitation in various fields. All over the world, this non-power nuclear energy is being favourably considered for different applications like radiation processing of polymeric materials, non-destructive testing, nuclear and nuclear-related analytical techniques, radiation sterilization of medical products and human tissue allografts, preservation of food by controlling the physiological processes for extending shelf-life and eradication of microbial and insect pests, nuclear technology in agriculture and treatment of sewage sludge. Bangladesh Atomic Energy Commission has taken radiation processing programmes in a big way right from its inception. This paper describes the studies carried out by various research groups in Bangladesh Atomic Energy Commission in the planning and development of non-power nuclear technology for peaceful uses in the fields of food, agriculture, medicine, industry and environment. Both food preservation and medical sterilization of medical products are now being commercially carried out in the Gammatech facility as a joint venture company of BAEC and a private entrepreneur. Bangladesh is soon going to establish a full-fledged Tissue Bank to cater the needs of various tissue allografts for surgical replacement. Recently Government of Bangladesh has allocated US$ 1.00 million for strengthening of the Tissue Banking Laboratory. Application of nuclear techniques in agriculture is also quite intensive. BAEC has made quite a good research contribution on vulcanization of natural rubber latex, wood plastic composites, surface coating curing, polymer modification etc. Bangladesh has also made a very good progress in the fields of non-destructive testing, tracer technology, nuclear analytical techniques and nucleonic control. The impact of non-power nuclear energy in selected areas will no doubt be significant in coming years. (Author)

  7. Renewable energy and rural development activities experience in Bangladesh

    Energy Technology Data Exchange (ETDEWEB)

    Barua, D.C.

    1997-12-01

    The per capita per year fuel consumption in Bangladesh is only 56 kg oil equivalent. The supply of electricity by Bangladesh power development board (BPDB) and Dhaka electricity supply authority (DESA) is mainly confined to cities and towns. Rural Electrification Board (REB) distributes electricity to the rural people through cooperatives. The rural cooperatives cover only 10% of the total population. Only about 15% of the total population is directly connected to the electricity. In order to meet the increasing energy demand for development of agriculture and industry and for the generation of better employment opportunities, it will be necessary to harness all the available alternative sources of energy immediately.

  9. Energy productivity and efficiency of wheat farming in Bangladesh

    International Nuclear Information System (INIS)

    Wheat is the second most important cereal crop in Bangladesh and production is highly sensitive to variations in the environment. We estimate productivity and energy efficiency of wheat farming in Bangladesh by applying a stochastic production frontier approach while accounting for the environmental constraints affecting production. Wheat farming is energy efficient with a net energy balance of 20,596 MJ per ha and energy ratio of 2.34. Environmental constraints such as a combination of unsuitable land, weed and pest attack, bad weather, planting delay and infertile soils significantly reduce wheat production and its energy efficiency. Environmental constraints account for a mean energy efficiency of 3 percentage points. Mean technical efficiency is 88% thereby indicating that elimination of inefficiencies can increase wheat energy output by 12%. Farmers' education, access to agricultural information and training in wheat production significantly improves efficiency, whereas events such as a delay in planting and first fertilization significantly reduce it. Policy recommendations include development of varieties that are resistant to environmental constraints and suitable for marginal areas; improvement of wheat farming practices; and investments in education and training of farmers as well as dissemination of information. - Highlights: • Bangladesh wheat farming is energy efficient at 20,596 MJha−1; energy ratio 2.34. • Environmental factors significantly influence productivity and energy efficiency. • Environmental factors must be taken into account when estimating wheat productivity. • Government policies must focus on ways of alleviating environmental factors. • Farmers' education, training and information sources increase technical efficiency

  13. Research and utilization of renewable energy resources in Bangladesh

    International Nuclear Information System (INIS)

    Bangladesh is an energy deficit and low-economy country with high population density. Per-capita energy consumption is one of the lowest in the world. The only dependable indigenous gas, which is the major primary energy source in the country, is used mainly for the production of electricity and fertilizer. If it is burnt at an annual 10% growth rate of consumption, may not last more than 15-20 years. Around 30% of the people of the country have connections to the national grid line. In the villages, where 80% of the population live, the situation is worse. Even if it is possible to take the electric grid line to all villages of the country, which will be an extremely difficult and expensive work to do, the majority of the village houses will not be able to have electric connections due to poverty. No nuclear power station exists in the country and the possibility of setting up any in the near future is limited due to non-availability of funds. Hydroelectric resources are also low because of the flat terrain of the country. The fuel import bill also occupies a significant portion of the total amount of export earnings. Conventional resources in Bangladesh are utterly inadequate for supplying the energy needs to bring in a significant improvement in our economy. On the other hand when our gas reserves will be exhausted it will be difficult for us even to maintain the energy supply for the development of our country unless we find alternate sources of energy. Solar energy availability in Bangladesh is high around 5KWH/day per meter square or 2.6 10/sup 11/ MWH/year on the total surface area of the country. This is equivalent to the output of about 30GW capacity utility plant for 100 years assuming 10% efficiency of the solar devices. Large-scale production of electricity from new, renewable energy sources is a great challenge. Wind power is difficult to exploit economically in regions with wind speeds bellow 5 m/s yearly average. Solar thermal power plants come

  14. Atomic energy utilization

    International Nuclear Information System (INIS)

    As observed worldwide, sufficient consensus has not been obtained on the peaceful utilization of atomic energy, but why has only France showed the relatively smooth advance ? Is it the result of the PR activities by enterprises ? The author visited two French nuclear facilities in June-July, 1990, and experienced the way of acceptance of the peaceful utilization of atomic energy and the action of enterprises in France. The French Electric Power Corp. (EDF) already clarified the guideline to the society about 'How to obtain the trust of public for atomic energy'. The gist of the contents of this EDF guideline is shown. The investigation by the authors can be judged as illustrating concretely the posture of enterprises to endeavor for the realization of this EDF guideline. The serious consideration on communication and community, the opening of information to public and sincere response, the fostering of the expression techniques of those in charge of PR, the immediate notice at the time of accidents, the maintenance of information transmission systems and so on carried out for 30 years contributed to the fostering of trust. The points of social psychology for national consensus and the investigation in the La Hague reprocessing plant and the Super Phenix in Creys Malville are reported. (K.I.)

    Energy used by street food vendors is effectively replacing fuel consumption in the household, as studies have shown that street foods are often cheaper to buy than to prepare at home. Rapid urbanisation has led to a proliferation of these very small food outlets, particularly in the Asian subcontinent. Street foods provide employment and income to millions of people around the world, and provide low cost, affordable food to low income people. The project pilot tested improved biomass stoves with a selection of street food vendors. In Sri Lanka, laboratory tests were undertaken with the following three stoves: improved rice-husk burner, biomass gasifier, and double-mouth chimney stoves. From the pilot testing in Sri Lanka the key findings are that the efficient gasifier stove is not suitable for street food vendors, but there were some promising results from larger biomass stoves. In Bangladesh, the project piloted four types of biomass stove: single mouth, double mouth, bucket-type and institutional stove. As these were more established, the pilot focused on a method for reaching a larger number of beneficiaries, people were trained to make stoves in their own and in others' houses. Five workshops were held and over 540 stoves were built. Impact assessment exercises were undertaken in both countries. (author)

    CERN Document Server

    Drukarev, Evgeny G

    2016-01-01

    This self-contained text introduces readers to the field of high-energy atomic physics - a new regime of photon-atom interactions in which the photon energies significantly exceed the atomic or molecular binding energies, and which opened up with the recent advent of new synchrotron sources. From a theoretical point of view, a small-parameter characteristic of the bound system emerged, making it possible to perform analytic perturbative calculations that can in turn serve as benchmarks for more powerful numerical computations. The first part of the book introduces readers to the foundations of this new regime and its theoretical treatment. In particular, the validity of the small-parameter perturbation expansion and of the lowest-order approximation is critically reviewed. The following chapters then apply these insights to various atomic processes, such as photoionization as a many-body problem, dominant mechanisms for the production of ions at higher energies, Compton scattering and ionization accompanied b...

    2010-10-04

    Bangladesh is facing daunting energy challenges: Security concerns over growing fuel imports, limited domestic energy resources for power generation, and projected demands for electricity that will exceed domestic supply capabilities within a few years. By acknowledging the potential of renewable energy resources, the country could possibly meet its unprecedented energy demand, thus increasing electricity accessibility for all and enhancing energy security through their advancement. The integration of renewable energy technologies in the power sector through national energy planning would, therefore, be a step in the right direction, not only for sustainable development of the country but also as part of Bangladesh's responsibility toward the global common task of environmental protection. This study estimates the potential of renewable energy sources for power generation in Bangladesh from the viewpoint of different promising available technologies. Future long-term electricity demand in Bangladesh is projected based on three economic growth scenarios. The energy planning model LEAP is applied to forecast the energy requirements from 2005 to 2035. Different policy scenarios, e.g., accelerated renewable energy production, null coal import, CO2 emission reduction targets and carbon taxes in the power sector from 2005 to 2035 are explored. The analyses are based on a long-term energy system model of Bangladesh using the MARKAL model. Prospects for the power sector development of the country are identified, which ensure energy security and mitigate environmental impacts. The technical potential of grid-connected solar photovoltaic and wind energy are estimated at 50174 MW and 4614 MW, respectively. The potential of energy from biomass and small hydro power plants is estimated at 566 MW and 125 MW, respectively. Total electricity consumption was 18 TWh in 2005 and is projected to increase about 7 times to 132 TWh by 2035 in the low GDP growth scenario. In the

  3. Present state of research and development of atomic energy in five Asian countries

    International Nuclear Information System (INIS)

    The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries. (Kako, I.)

  4. Preemption - atomic energy

    International Nuclear Information System (INIS)

    While waiting for the federal government to develop a nuclear waste disposal strategy, California enacted legislation that bans the construction of nuclear reactors until permanent disposal technology for high-level wastes is demonstrated and approved. The US Supreme Court upheld this prohibition in Pacific Gas and Electric Co. v. State Energy Resources Conservation and Development Commission. The Court found that the California law did not attempt to regulate the construction or operation of a nuclear plant nor to infringe on federal regulation of radiation safety and nuclear wastes. The moratorium is a legitimate move by the state to avoid economic uncertainties. Federal preemption of the law would empower utilities to determine state energy needs and programs. 131 references

  9. Environmental policy considerations and renewable energy in Bangladesh

    International Nuclear Information System (INIS)

    Energy is a critical commodity. It functions as a factor of production, as a process feedstock and as a consumer goods. It determines the shape of the life of individuals and that of the total economy. The evidence all over the world has shown a positive association between per capita income and per capita consumption. In fact over the world has consumption is now regarded as one of the important indices of economic development. Economic development is seen to have been accompanied by substitution of one form of energy by another As an economy develops, its demand for energy tends to increase and its consumption pattern in terms of energy forms and energy sources tends changes. But the stock of known viable sources of energy particularly commercial fuels are exploitation of energy sources involves a large investment and long gestation period. These and other related considerations emphases the need for taking a long-run view on demand and supply aspects of energy with particular focus on renewable energy. This further requires necessary policy considerations, which should be favorable for long term and sustained development of renewable energy. (Author)

  10. Energy utilization and environmental aspects of rice processing industries in Bangladesh

    International Nuclear Information System (INIS)

    In this study, the energy utilization and environmental aspects of the rice processing industries in Bangladesh was analyzed. Rice husk, a milling by-product of rice, is used as a source of thermal energy to produce steam for parboiling of raw rice. The rice is mostly dried on a concrete floor under the sunshine. In mechanical drying, rice husks are used as a source of primary energy. In Bangladesh, the annual estimated energy used in 2000 for the drying of rice by sunshine was 10.7 million GJ and for drying and parboiling by rice husks it was 48.2 million GJ. These amounts will increase to 20.5 and 92.5 million GJ in 2030, respectively. Electrical energy consumption for mechanical drying and milling of rice was calculated as 1.83 million GJe and 3.51 million GJe in 2000 and in 2030, respectively... Biogenic carbon dioxide emission from burning of rice husk is renewed every year by the rice plant. Both the biogenic and non-biogenic carbon dioxide emissions in 2000 were calculated as 5.7 and 0.4 million tonnes, respectively, which will increase to 10.9 and 0.7 million tonnes in 2030. The demand of energy for rice processing increases every year, therefore, energy conservation in rice processing industries would be a viable option to reduce the intensity of energy by increasing the efficiency of rice processing systems which leads to a reduction in emissions and an increased supply of rice husk energy to other sectors as well.

    As the 21st century is expected to induce a Knowledge based society, responding to this kind of change on our own initiative could be achieved by establishing networks among atomic energy agencies with the Atomic Energy Portal Site in a pivotal role. Thus, enabling the knowledge information from each agency to be easily shared and utilized. Furthermore, it can contribute to further researches by providing accumulated knowledge in the atomic energy, such as research output and past achievements, and by avoiding the repetition of researches on the same subjects. It could also provide remote educational data to researchers and industrial experts in atomic energy, as well as atomic energy information for general public consistently, so that we can promote our confidence in atomic energy

    Dewan Mowdudur Rahman

    2012-04-01

    Full Text Available Deficiency in energy sector is a major problem, which can hinder the development workflow of any country. Being the eighth most populated country in the world with a total electricity generation of only about 5000 MW and consumption of 144 kWh per capita, Bangladesh is one of the most electricity-deprived countries around the globe. In addition, absence of adequate investment and mass people awareness is a major problem in this country. Therefore, it would be very difficult to achieve overall progress without ensuring energy security by utilizing the promising renewable energy sources. In order to achieve the Millennium Development Goal (MDG, it is must for a third world country like Bangladesh to address the issue of energy deficiency promptly. In this context, renewable energy is the sustainable solution of energy security as well as social, environmental and economical problems. This paper summarizes the current energy scenario of Bangladesh, impacts of pollution from conventional energy sources, prospects of renewable energy development, and estimates the total investment required in Bangladesh to promote renewable energy sector by the year 2020.

    International Nuclear Information System (INIS)

    The objective of this paper is to analyse the existing energy system of Bangladesh and its testing inspection and maintenance needs under varying conditions and to examine the safety considerations of in-service welding, complexity evaluation of NDT application and applicability of alternative methods. A case study for such application is also included. Indications are also made about the preparatory needs in meeting future demand in terms of manpower, technology, equipment and activities by the turn of the century, so far as the bodies operating in these sectors are concerned. This is done keeping in view of the fact that NDT area is not in a static condition as sophisticated equipment, improved procedures and new innovations keep springing up. (author)

  17. Atomic energy indemnification system in Japan

    International Nuclear Information System (INIS)

    The Japanese legislation on the indemnification by atomic energy enterprisers for atomic energy damages, published in 1961 and enforced in 1962, includes the law concerning indemnification for atomic energy damages and the law concerning atomic energy damage indemnification contracts (hereafter referred to as ''the law concerning indemnification contracts''). While the Japanese laws are same as the foreign legislation in the provisions of the responsibility of atomic energy damages without the error of atomic energy enterprisers, exemption reasons are more important in this respect. When damages are due to exceptionally grave natural disasters or social disturbances, atomic energy enterprisers are exempted from the responsibility. Indemnification amounts are determined, but the Japanese laws do not limit then, different from the foreign regulations. The periods for demanding indemnification are not defined particularly in the law concerning indemnification contracts, and the general basic rules of the civil law are applied. As a result, the demand right terminates in 3 years after the injured persons find damage and offenders, and in 20 years since the unlawful act (Article 724, Civil law). The indemnification liability for atomic energy damages is focused on atomic energy enterprisers concerned in the same way as the foreign laws. The measures for assuring the execution of indemnification responsibility consist in principle of the firm conbination of the liability insurance contracts with private insurance companies and the indemnification contracts for atomic energy damages with the state. The damages of employes suffered in works are excluded from indemnification, which has been the main issue of discussion since the enactment of atomic energy laws. (Okada, K.)

  18. Atomic energy in Latin America

    International Nuclear Information System (INIS)

    Most countries in Latin America, including all those on the mainland, are Members of the Agency. Interest in the possibilities of nuclear energy has led to considerable activity, much of it in direct collaboration with the IAEA. Member States in the region are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela. Of these, Argentina, Brazil, Colombia and Venezuela are operating, and Mexico and Uruguay are constructing, research reactors, while Chile and Peru are studying proposals. Argentina, Brazil, Mexico and Uruguay have all agreed to accept Agency safeguards for reactors. The possibility of future needs for nuclear power is under examination by several countries, in some cases being related to desalination of water. All atomic work in Latin America is devoted to peaceful uses, and note-worthy progress has been made with proposals for a treaty which would make the whole region a militarily de-nuclearized zone. It is proposed that when this comes into effect the Agency will be asked to apply the controls developed in its safeguards system, and to carry out the inspections necessary to establish that work in progress is solely for peaceful purposes

  1. Research achievements in Bangladesh agriculture using nuclear techniques

    International Nuclear Information System (INIS)

    Application of isotope and radiation techniques in Bangladesh agriculture has been initiated in 1961 with the establishment of Atomic Energy Agricultural Research Centre, Dhaka under the then Pakistan Atomic Energy Commission. The activity of the centre was strengthened and upgraded to the level of an institute as a constituent organization of Bangladesh Atomic Energy Commission in 1972. It was further reorganized, made an autonomous research organization under the Ministry of Agriculture in 1982 and renamed as Bangladesh Institute of Nuclear Agriculture. The other organizations involved in nuclear agricultural research are Institute of Food and Radiation Biology and Bangladesh Agricultural University. A number of technologies have been developed using nuclear techniques that imparted on agricultural development. Sixteen new crops were developed using physical (200-700 Gy gamma rays) and chemical mutagen (NaN3). Soil fertility and plant nutrition technologies were developed using both stable and radio isotopes. The improved feeding strategies and utilization of locally available low quality feed material (rice straw) were determined using 51Cr-EDTA and 125I in order to have better livestock growth and reproduction ability. Several constraints related to nuclear research were identified. Increased government commitment and international cooperation are of the utmost importance for effective utilization of the benefits of nuclear technology and to face the increasing demand for food for the ever increasing population in years to come

  3. Photovoltaics as a renewable energy technology in Bangladesh and its potential for increasing welfare, gender equity, and environmental sustainability

    Science.gov (United States)

    Chowdhury, Sarwat

    Situated in the northeast corner of the South Asian sub-continent, Bangladesh is a developing country with high population density, low life expectancy, low rate of literacy and extremely low access to modern energy sources. Lack of access to electrification remains a major constraint to the country's economic development. In this context, as in other countries, Bangladeshi development practitioners have tended to pursue outputs that rely on new technologies as a means to leapfrog to higher levels of development. However, independent analysis of such efforts, in terms of achieving sustainable development outcomes, remains lacking. The full potential of renewable energy technologies in Bangladesh has yet to attract widespread recognition from policy makers. In this thesis, I review solar PV technology since it has already been attempted as a rural off-grid electrification option in Bangladesh. I argue that the applications of technology should follow, and not precede, considerations for human well-being. It is also important to have a more holistic perspective on human welfare, which should include the basic dimensions of choice and opportunities, and not just income levels. The Government of Bangladesh and its development partners need to expand support to renewable energy technologies and so redirect the focus of policy formulation and implementation to sustainable human development. I emphasize that people-centered public policy has a key role to play in the introduction of a technology such as the solar photovoltaics pioneered by Grameen Shakti, a not-for-profit company in Bangladesh. While equity in terms of a fair distribution of wealth and income may continue to be an illusion, innovations such as solar PV are indeed promising with respect to opening up opportunities and possible benefits for women, the environment and---more generally---human well-being. This thesis is based on work in rural areas complementary to various professional responsibilities that I

    2015-10-01

    Full Text Available This paper presents the assessment of the electrical power generation potential from municipal solid waste (MSW in Rajshahi City Corporation (RCC, Bangladesh. RCC generates huge amount of solid waste (SW which is left very poorly managed due to crisis in governance. About 80% of organic food wastes are the major constituents of SW generated in RCC in the year 2012. Electrical energy can be produced from SW generated in RCC as a sustainable commercial solution. The average calculated value of heat content of MSW of the year 2012 based on the data of MSW of 2005 (MSW: 2005 and MSW of 2012 (MSW: 2012 is 7234.5 kJ/kg, which is sufficient to produce electricity. Integrated sustainable waste management (ISWM has to be put into operation to harness energy from MSW. A 645.543 ton/day energy recovery Mass Burn Incinerator (MBI system of 19.71% overall efficiency is to be used. It is found that potential of electrical energy generation from MSW in RCC during the years 2012 and 2025 is 5.336 MW and 10.568 MW respectively.

    . Accordingly the government has the vision to provide electricity to all by 2021. Over the years, due to lack of indigenous energy resources, Bangladesh has become more or less a gas dependent mono energy based country. From studies and surveys it is focused that the country has limited reserve of gas and it is apprehended if natural gas is used at the present rate, this would result in complete depletion of the existing reserves within a short time. So Bangladesh urgently needs to reduce dependence on its indigenous natural gas. Coal as fuel has potential, however, exploitation of it has intricate socio-environmental issues. Under this scenario Nuclear power is an inevitable option for Bangladesh to meet her energy security. The 'clean'' nuclear power can be a great boon and this proven and matured technology is thus the response to our needs for energy security. With the rapid changes in global as well as domestic conditions of energy and power generation, our government took some positive initiatives to implement NPP within the shortest possible time. The government has reflected her nuclear vision in the Revised Draft of the National Energy Policy. Accordingly a supporting project on NPP to accomplish essential activities to Implement Rooppur Nuclear Power Plant' (RNPP) is under execution. Bangladesh Atomic Energy Commission (BAEC) has started necessary activities such as updating and finalizing the Site Safety Report of RNPP; Bid Invitation Specification documents, Comprehensive Nuclear Law and other infrastructure development activities for starting construction of a NPP by 2010. BAEC prepared a comprehensive Self-evaluation Document on NPP. The IAEA conducted a mission to Bangladesh for reviewing the infrastructure established for construction of NPP based on integrated infrastructure evaluation methodology.

  12. The Future of Atomic Energy

    Science.gov (United States)

    Fermi, E.

    1946-05-27

    There is definitely a technical possibility that atomic power may gradually develop into one of the principal sources of useful power. If this expectation will prove correct, great advantages can be expected to come from the fact that the weight of the fuel is almost negligible. This feature may be particularly valuable for making power available to regions of difficult access and far from deposits of coal. It also may prove a great asset in mobile power units for example in a power plant for ship propulsion. On the negative side there are some technical limitations to be applicability of atomic power of which perhaps the most serious is the impossibility of constructing light power units; also there will be some peculiar difficulties in operating atomic plants, as for example the necessity of handling highly radioactive substances which will necessitate, at least for some considerable period, the use of specially skilled personnel for the operation. But the chief obstacle in the way of developing atomic power will be the difficulty of organizing a large scale industrial development in an internationally safe way. This presents actually problems much more difficult to solve than any of the technical developments that are necessary, It will require an unusual amount of statesmanship to balance properly the necessity of allaying the international suspicion that arises from withholding technical secrets against the obvious danger of dumping the details of the procedures for an extremely dangerous new method of warfare on a world that may not yet be prepared to renounce war. Furthermore, the proper balance should be found in the relatively short time that will elapse before the 'secrets' will naturally become open knowledge by rediscovery on part of the scientists and engineers of other countries.

    This report presents a comparative study of long-term energy demand and potential greenhouse gas emissions projections from energy demand and supply sectors in Bangladesh covering the period 2000 to 2020. The study was conducted employing the IAEA's tool ENPEP- BALANCE model. This study presents a reliable energy system plan with minimal carbon emission for the country. Primary energy demands distributed by energy carriers and electricity demand have been projected based on macro-economic growth scenarios constructed for national energy policy of 1996. The conservation of indigenous energy resources was emphasized to build a long-term secured energy supply system. The potential energy supply options including nuclear energy and prospective greenhouse gas mitigation options were analyzed

    2015-01-01

    A pseudopotential for positronium-atom interaction, based on electron-atom and positron-atom phase shifts, is constructed, and the phase shifts for Ps-Kr and Ps-Ar scattering are calculated. This approach allows us to extend the Ps-atom cross sections, obtained previously in the impulse approximation [Phys. Rev. Lett. 112, 243201 (2014)], to energies below the Ps ionization threshold. Although experimental data are not available in this low-energy region, our results describe well the tendency of the measured cross sections to drop with decreasing velocity at $v<1$ a.u. Our results show that the effect of the Ps-atom van der Waals interaction is weak compared to the polarization interaction in electron-atom and positron-atom scattering. As a result, the Ps scattering length for both Ar and Kr is positive, and the Ramsauer-Townsend minimum is not observed for Ps scattering from these targets. This makes Ps scattering quite different from electron scattering in the low-energy region, in contrast to the inter...

    In this work, atomic calculations were performed within the local-density and generalized-gradient approximations of exchange and correlation density functionals within density-functional theory to provide accurate periodic trends of first ionization energies and electron affinities of the atomic series from hydrogen to xenon. Electronegativities were determined directly from Mulliken's formula and were shown to be equivalently calculated rather by using Slater-Janak's transition state or by calculating the electrostatic self-energies of the orbitals involved in the transition to ions. Finally, comparisons were made with other theoretical and experimental results, including Mulliken-Jaff\\'e's electronegativity scale.

  5. Peaceful uses of atomic energy

    International Nuclear Information System (INIS)

    The IAEA's statutory mandate is to promote all applications of nuclear energy for peaceful purposes. While non-power applications - in agriculture, medicine, industry, etc. - have become widely used and mostly accepted, nuclear power has become more controversial and is facing serious public acceptance problems. Public concern centres on three issues - radioactive wastes, nuclear accidents and the risk of nuclear weapons proliferation. Any discussion of the acceptability or desirability of nuclear power is meaningful only if the alternatives are considered in parallel. The role of nuclear power and other energy sources in electricity generation is discussed and the factors in favour of nuclear energy outlined. Although the Chernobyl accident had strong impact on public opinion in many countries, it has until now had small direct impact on the prospects of nuclear power in the world as a whole. The IAEA's nuclear safety activities and the post-Chernobyl strengthening of international cooperation to minimise nuclear accident consequences are described. The IAEA's safeguards system and its application to Australia's uranium are reviewed. Through this system with its on-site inspections, the IAEA continuously verifies that nuclear materials and nuclear installations submitted to it (some 95% of all fissionable material and of all installations in non-nuclear weapon states) remain in exclusively peaceful use

  9. Zero-point energy of ultracold atoms

    Science.gov (United States)

    Salasnich, Luca; Toigo, Flavio

    2016-06-01

    We analyze the divergent zero-point energy of a dilute and ultracold gas of atoms in D spatial dimensions. For bosonic atoms we explicitly show how to regularize this divergent contribution, which appears in the Gaussian fluctuations of the functional integration, by using three different regularization approaches: dimensional regularization, momentum-cutoff regularization and convergence-factor regularization. In the case of the ideal Bose gas the divergent zero-point fluctuations are completely removed, while in the case of the interacting Bose gas these zero-point fluctuations give rise to a finite correction to the equation of state. The final convergent equation of state is independent of the regularization procedure but depends on the dimensionality of the system and the two-dimensional case is highly nontrivial. We also discuss very recent theoretical results on the divergent zero-point energy of the D-dimensional superfluid Fermi gas in the BCS-BEC crossover. In this case the zero-point energy is due to both fermionic single-particle excitations and bosonic collective excitations, and its regularization gives remarkable analytical results in the BEC regime of composite bosons. We compare the beyond-mean-field equations of state of both bosons and fermions with relevant experimental data on dilute and ultracold atoms quantitatively confirming the contribution of zero-point-energy quantum fluctuations to the thermodynamics of ultracold atoms at very low temperatures.

    2015-01-01

    Theories of dark energy require a screening mechanism to explain why the associated scalar fields do not mediate observable long range fifth forces. The archetype of this is the chameleon field. Here we show that individual atoms are too small to screen the chameleon field inside a large high-vacuum chamber, and therefore can detect the field with high sensitivity. We derive new limits on the chameleon parameters from existing experiments, and show that most of the remaining chameleon parameter space is readily accessible using atom interferometry.

    2016-04-01

    We review the tantalising prospect that the first evidence for the dark energy driving the observed acceleration of the universe on giga-parsec scales may be found through metre scale laboratory-based atom interferometry experiments. To do that, we first introduce the idea that scalar fields could be responsible for dark energy and show that in order to be compatible with fifth force constraints, these fields must have a screening mechanism which hides their effects from us within the solar system. Particular emphasis is placed on one such screening mechanism known as the chameleon effect where the field's mass becomes dependent on the environment. The way the field behaves in the presence of a spherical source is determined and we then go on to show how in the presence of the kind of high vacuum associated with atom interferometry experiments, and when the test particle is an atom, it is possible to use the associated interference pattern to place constraints on the acceleration due to the fifth force of the chameleon field - this has already been used to rule out large regions of the chameleon parameter space and maybe one day will be able to detect the force due to the dark energy field in the laboratory.

    Atomic interferometry can be used to probe dark energy models coupled to matter. We consider the constraints coming from recent experimental results on models generalising the inverse power law chameleons such as $f(R)$ gravity in the large curvature regime, the environmentally dependent dilaton and symmetrons. Using the tomographic description of these models, we find that only symmetrons with masses smaller than the dark energy scale can be efficiently tested. In this regime, the resulting constraints complement the bounds from the E\\"otwash experiment and exclude small values of the symmetron self-coupling.

    The linear and mass attenuation coefficients of different types of soil, sand, building materials and heavy beach mineral samples from the Chittagong and Cox's Bazar area of Bangladesh were measured using a high-resolution HPGe detector and the gamma-ray energies 276.1, 302.8, 356.0, 383.8, 661.6 and 1173.2 and 1332.5 keV emitted from point sources of 133Ba, 137Cs and 60Co, respectively. The linear attenuation coefficients show a linear relationship with the corresponding densities of the samples studied. The variations of the mass attenuation coefficient with gamma-ray energy were exponential in nature. The measured mass attenuation coefficient values were compared with measurements made in other countries for similar kinds of materials. The values are in good agreement with each other in most cases. PMID:11300413

    International Nuclear Information System (INIS)

    New personality in atomic energy consists of personification of independence, democracy and publication. They are able to create new technologies and new plants with safety and maintenance. The technical experts and all the parties concerned have to explain the situation and the conditions of atomic energy in order to justify the people's trust in them. Only good personality with morals can obtain the confidence of the nation. It is important for new technical experts and all the parties concerned to receive an education related to sociality.

  11. European atomic energy law. Nuclear energy laws. 2. ed.

    International Nuclear Information System (INIS)

    The present re-edition closes a gap that had existed in particular in the German literature on European atomic energy law. This field of law is becoming more and more important through the introduction of new directives and regulations. The textbook starts with a discussion of the principles and international regulations of European atomic energy law. Forming its core is a presentation of the Euratom Treaty with all its regulations, directives, and decisions taken by the European Commission and the European Court of Justice. Since the Fukushima disaster, and as a result of the still ongoing renaissance of nuclear energy in many countries outside of Europe, a substantial demand has grown for information on international and specifically European nuclear energy law.

  12. The industrial development of atomic energy

    International Nuclear Information System (INIS)

    Countries with large stock of fissile material and producing large quantity of nuclear pure 235U and 239Pu are able to allocate part of the stock to non military research. For countries with low stock of fissile material, all the stock is allocated to military research. An economical and technical solution has to be find to dedicate a part of fissile material to non military research and develop the atomic energy industry. It stated the industrial and economical problems and in particular the choice between the use of enriched fuel with high refining cost or depleted fuel with low production cost. It discusses of four possible utilizations of the natural resources: reactors functioning with pure fissile material (235U or 239Pu) or concentrated material (235U mixed with small quantities of 238U after an incomplete isotopic separation), breeder reactors functioning with enriched material mixed with 238U or Thorium placed in an appropriate spatial distribution to allow neutrons beam to activate 238U or Thorium with the regeneration of fissile material in 239Pu, reactors using natural uranium or low enriched uranium can also produce Plutonium with less efficiency than breeder reactors and the last solution being the use of natural uranium with the only scope of energy production and no production of secondary fissile material. The first class using pure fissile material has a low energy efficiency and is used only by large fissile material stock countries to accumulate energy in small size fuel for nuclear engines researches for submarines and warships. The advantage of the second class of reactors, breeder reactors, is that they produce energy and plutonium. Two type of breeder reactor are considered: breeder reactor using pure fissile material and 238U or breeder reactor using the promising mixture of pure fissile material and Thorium. Different projects are in phase of development in United States, England and Scotland. The third class of reactor using natural

    2015-01-01

    If dark energy---which drives the accelerated expansion of the universe---consists of a new light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. There has, however, been much theoretical progress in developing theories with screening mechanisms, which can evade detection by suppressing forces in regions of high density, such as the laboratory. One prominent example is the chameleon field. We reduce the effect of this screening mechanism by probing the chameleon with individual atoms rather than bulk matter. Using a cesium matter-wave interferometer near a spherical mass in an ultra-high vacuum chamber, we constrain a wide class of dynamical dark energy theories. Our experiment excludes a range of chameleon theories that reproduce the observed cosmic acceleration.

  14. Constitutionality of the Atomic Energy Act

    International Nuclear Information System (INIS)

    Roma locuta, causa finita. The Federal Constitutional Court declared in its decree of 8 August 1978 the peaceful uses of nuclear energy (Paragraph 7 sub-section 1 and 2 Atomic Energy Act) in NPPs of the so-called fast breeder type as constitutional for the time being. The excellent simplicity of the explanations, namely about the anavoidability and social adequancy of the so-called residual risk in a highly technical society and about the determining influence of practical ratio as a measure for the estimation of the residual risk which must be born by all citizens, creates a good clarification on the level of constitutional law. However, it remains, to be seen whether the decree can give the administrative courts any orientation help in the future and whether it will lead to an improved legal protection of all participants and a more effective handling of administrative processes.

  20. Spotlight: Bangladesh.

    Science.gov (United States)

    1998-01-01

    This brief article highlights the progress made in Bangladesh in reducing fertility and improving women's status. The mid-1997 population was an estimated 122.2 million persons. The land area is 50,260 square miles. Population density was 2432 people per square mile. Births were 31 per 1000 persons. Deaths were 11 per 1000 persons. Infant deaths were 77 per 1000 live births. Natural increase was 2% per year. The total fertility rate was 3.3 births per woman. Life expectancy was 58 years for males and females. Bangladesh is one of the most densely populated countries in the world and has about 50% of US population situated on land the size of Wisconsin. Average annual income is about $240. Livelihoods from agriculture are affected by monsoons and natural disasters. Bangladesh has reduced its fertility by half since the mid-1970s. Almost 50% of married women relied on contraception during 1996-97, compared to only 8% of married women in 1975. Increases in contraceptive prevalence are attributed to the family planning program and parents' desire for smaller families. The government has made slowing population growth a priority since the 1970s. The 35,000 field workers provide door-to-door contraception and counseling. Mass media has promoted messages about the economic and health advantages of limiting or spacing births. Women continue to play a subordinate role to men, despite their improved control over fertility. Under 30% of women are literate compared to 50% of men. Islamic practices still confine women to the home. Programs are directed to improving women's financial status through credit programs. Women now hold many jobs in the new garment industry, which is the largest nonagricultural employer.

  1. Energy productivity and efficiency of the ‘gher’ (prawn-fish-rice) farming system in Bangladesh

    International Nuclear Information System (INIS)

    ‘Gher’ farming is a unique system that incorporates the joint operation of three enterprises: freshwater prawn, fish and HYV rice, and is expanding rapidly in the coastal regions of Bangladesh because of its proven high income earning potential. In this paper, the sustainability of this system is evaluated by analysing its performance in terms of energy use by applying a stochastic distance function approach which revealed interesting and unexpected results. The prawn enterprise which is the key income earning component is found to be technically inefficient while the rice enterprise is found to be efficient. The net energy balance and the energy use efficiency of the ‘gher’ farming system is estimated at 18,510 MJ ha−1 and 1.72 respectively. The ‘gher’ farmers are operating at a very high level of technical (energy) efficiency (92%). Diversification amongst enterprises is associated with technical (energy) inefficiency. However, larger operation size enhances efficiency. The key policy implication is that the ‘gher’ farming system can be sustained in the long run provided that productivity from the rice enterprise remains high. Also, policies to support the expansion of ‘gher’ farm sizes will improve efficiency. -- Highlights: ► Sustainability of gher farming system is evaluated in terms of energy use. ► The prawn enterprise is technically inefficient while rice enterprise is efficient. ► The net energy balance is 18,510 MJ ha-1 and energy use efficiency is 1.72. ► The overall technical (energy) efficiency is very high (92%). ► The gher farming system can be sustained if rice productivity remains high.

  4. Israel Atomic Energy Commission 1997 Annual Report

    International Nuclear Information System (INIS)

    The 1997 Annual Report is published in a special year for Israel, marking the 50th anniversary of its independece and statehood. From its inception, and the election of a distinguished scientist as its first president, Israel has regarded science and technology as a central pillar for future AEC development and a lever for improved quality of life of its people. The Israel Atomic Energy Commission, which will be celebrating its own anniversary in a few years, has made a modest but significant contribution to the establishment and growth of the technological infrastructure of the country. The first article in this Annual Report focuses attention on yet another aspect of our continuing investigation of the basic properties of technologically interesting and important materials, presented in our 1994 and 1996 Annual Reports. The current entry describes an application of the nuclear Time Differential Perturbed Angular Correlation technique to the study of the structure and properties of metal-hydrogen compounds, of potential interest within the framework of future, environmentally attractive hydrogen-burning energy systems, and in fusion power reactors. The second article also relates to some basic aspects of nuclear fusion. A theoretical study of the behavior and properties of laser-generated hot plasmas resulted in the proposal of a new confinement scheme, in which a plasma generated by circularly polarized laser light is confined in a miniature magnetic bottle created by magnetic fields induced in the plasma by the same light. The paper discusses the conditions under which such confinement and ensuing energy gain may be achieved. Measurements of actual axial magnetic fields generated in plasma by intense circularly polarized laser light are also reported. The third report describes one of our ongoing efforts to improve and streamline the techniques and procedures used in medical applications of radioisotopes.

  6. Israel Atomic Energy Commission 1996 Annual Report

    International Nuclear Information System (INIS)

    Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission's Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty. Of the many worthwhile projects, four were chosen to represent best the current trends in the continuing R and D program at the research centers of the Israel Atomic Energy Commission. One of these trends is the growing cooperation with private industry, in an attempt to gear our R and D programs to respond to market demands. Another feature, noted already several years ago, is the extensive collaboration of our scientists and engineers with colleagues at other institutions, in Israel and abroad. some of the work reported is part of evolving international industrial cooperation projects, illustrating both these trends. Following a trend common to many nuclear research centers around the world, a substantial part of our research effort is non-nuclear in nature. This is illustrated in the first article, which deals with advances in the application of non-linear optics in diverse fields of science and technology. These include state-of-the-art solid-state lasers, rapid modulation of light signals, development and generation of tunable sources of coherent light, optical data storage and the microscopic probing of biological and inorganic samples. The present work reports on a range of R and D, from the fundamentals of non-linear optical materials to proof-of-principle demonstrations of non-linear subwavelength resolution microscopy, to fabrication of prototype commercial tunable laser systems The second report considers the microstrain characteristics in some alloys using X-ray diffraction (XRD). The research utilizes XRD line broadening effects to study the characteristics of alloys from especially prepared surfaces. These characteristics include the homogeneity of alloying

  7. Atomic energy policy in fiscal year 1985

    International Nuclear Information System (INIS)

    The international demand and supply of petroleum advance in relaxed condition at present, but tend to get stringent in long term. Nuclear power is the most promising substitute energy for petroleum, and in Japan, 28 nuclear power plants with 20.56 million kW output are in operation, generating 20.4% of the total generated power in 1983. According to the perspective of long term power supply, the installed capacity of nuclear power plants will reach 62 million kW and 27% of the total installed capacity by 2000. It is important to positively deal with the industrialization of nuclear fuel cycle, the upgrading of nuclear power generation, the development of the reactors of new types and so on, preparing for the age that nuclear power generation will become the center of power supply. The atomic energy policy of the Ministry of International Trade and Industry in fiscal year 1985 is reflected to the budget, financial investment and funding and other measures based on the above viewpoint. The outline of the budget and financial investment and funding for fiscal year 1985 is explained. The points are the promotion of industrialization of nuclear fuel cycle, the promotion of nuclear power generation and the promotion of understanding and cooperation of nation on the location of electric power sources.

  9. Magnetospheric imaging with low-energy neutral atoms.

    OpenAIRE

    1991-01-01

    Global imaging of the magnetospheric charged particle population can be achieved by remote measurement of the neutral atoms produced when magnetospheric ions undergo charge exchange with cold exospheric neutral atoms. Previously suggested energetic neutral atom imagers were only able to measure neutral atoms with energies typically greater than several tens of keV. A laboratory prototype has been built and tested for a different type of space plasma neutral imaging instrument, which allows ne...

  10. International Atomic Energy Agency activities in decommissioning

    International Nuclear Information System (INIS)

    Full text: The International Atomic Energy Agency (IAEA) has been addressing the safety and technical issues of decommissioning for over 20 years, but their focus has been primarily on planning. Up to know, the activities have been on an ad hoc basis and sometimes, important issues have been missed. A new Action Plan on the Decommissioning of Nuclear Facilities has recently been approved by the Agency's board of Governors which will focus the Agency's efforts and ensure that our Member States' concerns are addressed. The new initiatives associated with this Action Plan will help ensure that decommissioning activities in the future are performed in a safe and coherent manner. The International Atomic Energy Agency (IAEA) has been preparing safety and technical documents concerning decommissioning since the mid-1980's. There have been over 30 documents prepared that provide safety requirements, guidance and supporting technical information. Many of these documents are over 10 years old and need updating. The main focus in the past has been on planning for decommissioning. During the past five years, a set of Safety Standards have been prepared and issued to provide safety requirements and guidance to Member States. However, decommissioning was never a real priority with the Agency, but was something that had to be addressed. To illustrate this point, the first requirements documents on decommissioning were issued as part of a Safety Requirements [1] on pre-disposal management of radioactive waste. It was felt that decommissioning did not deserve its own document because it was just part of the normal waste management process. The focus was mostly on waste management. The Agency has assisted Member States with the planning process for decommissioning. Most of these activities have been focused on nuclear power plants and research reactors. Now, support for the decommissioning of other types of facilities is being requested. The Agency is currently providing technical

    Bangladesh has thirteen Nuclear Medical Centres and one Institute of Nuclear Medicine in the country which are being run and maintained by the physicians scientists and engineers of Bangladesh Atomic Energy Commission. The peaceful application of atomic energy was initiated through all these Centres with the use of clinical isotopes for thyroid and kidney studies. The equipment used for these purposes were the thyroid uptake system, rectilinear scanner and the multiprobe renogram system. The first gamma camera was installed in the country in 1980 at the Institute of Nuclear Medicine, Dhaka. That was the turning point for the country in the field of nuclear medicine. Presently all the nuclear medical establishments are equipped least with a gamma camera, thyroid uptake system and a renogram system. In the last two decades there has been a tremendous development in the design of nuclear medical equipment. Most of the old equipments were slow and manually operated. In the beginning of nineties of the past centur...

    The local atomic bonding of carbon atoms around the edge of graphene is examined by aberration-corrected scanning transmission electron microscopy (STEM) combined with electron energy loss spectroscopy (EELS). High-resolution 2D maps of the EELS combined with atomic resolution annular dark field STEM images enables correlations between the carbon K-edge EELS and the atomic structure. We show that energy states of graphene edges vary across individual atoms along the edge according to their specific C-C bonding, as well as perpendicular to the edge. Unique spectroscopic peaks from the EELS are assigned to specific C atoms, which enables unambiguous spectroscopic fingerprint identification for the atomic structure of graphene edges with unprecedented detail.

    An explorative survey was carried out on rural and semi-urban households to find out the energy consumption pattern with respect to socio-demographic and geographic factors in Bangladesh by using stratified random sampling technique. The study revealed that 100% of the households used biomass, 98% kerosene, 61% electricity, 23% LPG and 5% candle in the rural areas. In the semi-urban areas, 100% of the households used electricity, candle and natural gas, 60% kerosene and 13% petrol. Households' mean expenditure for total energy was US$ 5.34 (SE, 0.43) with total income US$ 209.84 (SE, 6.69) month{sup -1} in the rural areas, while it was US$ 6.20 (SE, 1.35) in the semi-urban areas with the total income US$ 427.76 (SE, 24.19) month{sup -1}. This study may be a useful baseline information to energy policy makers in Bangladesh. - Highlights: >The study provides an empirical analysis of household energy consumption. > Rural households are dominated by biomass energy. > Semi-urban households are dominated by standard commercial energy (natural gas and electricity).> Monthly income, dwelling status and literacy of the households clearly influences energy use.> The major energy use in the rural households is for the cooking purpose.

  18. Young students's opinion about atomic energy

    International Nuclear Information System (INIS)

    The present research work was performed in answer to a requirement that the CNEA-RC made to students of the Public and Institutional Relations Degree of the UES21, as a part of activities carried out in the framework of the Academic Cooperation Agreement between both institutions. In this case the students had to attend the Professional Practical course during the first semester of 2006, which included a short period in some company or organization. The Degree of Knowledge and the Opinion of the students from the Cycle of Specialization of the Province of Cordoba Educational System (ages between 15 and 17 years old), on the activities that are made in the site of CNEA-RC and DIOXITEK SA at Alta Cordoba neighborhood in Cordoba city has been analyzed. The same aspects were analyzed for Dioxitek's activities (equipment, raw materials, risk performance, etc.). Although the activities made at CNEA-RC involved during 2005/6 about 4000 students, due to the short time available for the practical part only the data of two schools located near the facilities were processed. Three aspects of the space conformed between the public and the general opinion were analyzed: the customs, the stereotypes and the attitudes of the people. These aspects were taken as the characteristics to describe to the opinions, their direction and intensity. The analysis was based on an exploratory investigation of type, characterized by its flexibility. The field work was of quantitative character. The surveys were structured with closed questions (categories of answers delimited previously on which the students must answer). For its design we used diverse sources of intelligence, such as pages of Internet, pamphlets, magazines, annual balances of the organizations, etc. The main results were the following: 1) The greater percentage of students declared to have little information on Atomic Energy. Only 4% declared to have abundant knowledge on the subject. 2) A 38% of the students indicated that

    International Nuclear Information System (INIS)

    In September 2009, considering the existing interest in public communication of scientific activities that are developed locally, a group of researchers and communicators from Córdoba, decided to form the Network of Outreach of Córdoba. Its stated objectives of the Constitutive Act are presented in this paper along with the main activities undertaken to date and plans for the future. Since that time, the Management of Institutional Relations of the CNEA in Córdoba became involved in public circulation of scientific knowledge, in what has proven to be a framework that ensures an adequate level of debate to present nuclear national activities. This will involve collaborative efforts with professional institutions involved in research, teaching and communicating science. The main objective was to encourage the transfer of knowledge to optimize available resources, improving the methodological approaches and generating creative products tailored to regional needs, in order to promote the democratization of science and nuclear technology. This paper consists of two parts. On the one hand describes the activities of the Network during the year 2011 shows results with particular emphasis on topics related to atomic energy, and secondly, shows the desirability of promoting such activities in the CNEA. Among the main actions considered, highlighting the institutional participation in the official Ministry of Science and Technology Fair participation in Science and Technology Provincial Cordoba 2011, issue of the radio program 'Green Light: Science and technology everyday life' by National Technological University Radio and a network of forty provincial stations, and active participation in the Course of Specialization in Public Communication of Science and Scientific Journalism, organized by the School of Information Sciences and the Faculty of Mathematics, Physics and Astronomy, National University of Cordoba, among others.

    We study three-body recombination of Ba++Rb +Rb in the mK regime where a single 138Ba+ ion in a Paul trap is immersed into a cloud of ultracold 87Rb atoms. We measure the energy dependence of the three-body rate coefficient k3 and compare the results to the theoretical prediction, k3∝Ecol-3 /4, where Ecol is the collision energy. We find agreement if we assume that the nonthermal ion energy distribution is determined by at least two different micromotion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed in an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s -wave regime.

    We study three-body recombination of Ba$^+$ + Rb + Rb in the mK regime where a single $^{138}$Ba$^{+}$ ion in a Paul trap is immersed into a cloud of ultracold $^{87}$Rb atoms. We measure the energy dependence of the three-body rate coefficient $k_3$ and compare the results to the theoretical prediction, $k_3 \\propto E_{\\textrm{col}}^{-3/4}$ where $E_{\\textrm{col}}$ is the collision energy. We find agreement if we assume that the non-thermal ion energy distribution is determined by at least two different micro-motion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed into an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s-wave regime.

    Experiments in atomic physics have exceptional sensitivity to small shifts in energy in an atom, ion, or bound particle. They are particularly well suited to search for unique low-energy signatures of new physics, including effects that could originate from the Planck scale. A number of recent experiments have used CPT and Lorentz violation as a candidate signal of new physics originating from the Planck scale. A discussion of these experiments and their theoretical implications is presented.

  10. Problems faced by Bangladesh in introducing a nuclear power programme

    International Nuclear Information System (INIS)

    The per capita energy resources and consumption of energy in Bangladesh are among the lowest in the world as in the per capita GDP of the country. The need for and importance of nuclear power in providing cheaper and reliable energy for economic development of the country is discussed in the light of this situation. The constraints faced by the Bangladesh Atomic Energy Commission (BAEC) in the initiation and development of a national nuclear power programme are detailed. Following the liberation of the country in 1971 its financial resources were mainly channelled to the rehabilitation and restoration of the economy. As the size of the national grid has remained relatively small, unit sizes in the range of 50-200MW(e) only could be considered for commissioning. Lack of vendor interest in such small sizes and the difficulty of arranging long-term investment for nuclear stations are the main constraints faced by the BAEC. Other bottlenecks are due to the uncertainty about the nature and extent of future economic development, pricing policy for available indigenous fossil fuel, and national energy planning criteria, which are mainly influenced by the limited financial resources, national priority for various essential non-development expenditures, which use up most of the country's own earnings and foreign aid, etc. Problems that are likely to be faced in future are discussed. These include public acceptability of nuclear power in Bangladesh, the obstacles to the transfer of nuclear technology that may be erected through the prospective growth of a cartel of nuclear-exporting countries, drainage of trained manpower, etc. (author)

    This paper has sought to show the potential of energy recovery from rurally available agro and household organic wastes and thus, the possible impact on supplementing energy demand, reducing deforestation, and replacing fossil fuel as well as avoided greenhouse gases. Results show that co......-digestion of a wide range of manure, crop residues and household wastes with cow manure was successful to produce increased gas yield than what would be if cow dung is digested separately and the energy value from this can supplement 57–79% of the rural energy demand, depending on the methane yield from organic waste...... mixtures. However, particularly considering for cooking purpose, it can save 1586–2213 Kg firewood/Household/year. Therefore, the results suggests that implementation of co-digestion in the centralized plant could be a viable solution to produce decentralized energy for the rural households in terms...

  12. Determination of Surface Exciton Energies by Velocity Resolved Atomic Desorption

    We have developed a new method for determining surface exciton band energies in alkali halides based on velocity-resolved atomic desorption (VRAD). Using this new method, we predict the surface exciton energies for K1, KBr, KC1, and NaC1 within +0.15 eV. Our data, combined with the available EELS data for alkali fluorides, demonstrate a universal linear correlation with the inverse inter-atomic distance in these materials. The results suggest that surface excitons exist in all alkali halides and their excitation energies can be predicted from the known bulk exciton energies and the obtained correlation plot.

    2014-12-01

    A modified static-exchange model is developed to study the collision of an atom with another atom. It includes the effect of long-range dipole–dipole van der Waals interaction between two atoms in addition to the exact effect of short-range force due to Coulomb exchange between two system electrons. Both these interactions dominate at colder energies. The system is treated as a four-centre problem in the centre-of-mass frame. The present ab-initio model is useful to study the two-atomic collisions at low energies, as well as cold energies. The new code is applied to study the scattering of positronium (Ps) by hydrogen (H), both in their ground states.

    1997-10-01

    Industrial Radiography arose out of the widespread applications of X-rays pioneered by Roentgen about 100 years back. It is routinely used in studying the integrity of structural materials and like most countries in the world, its use in Bangladesh is increasing at a faster rate. This is because Bangladesh is a developing country of 3rd world and in the backdrop of agrarian poverty ridden economy, its population may exceed 125 millions by 2000 AD, leaving some 12 millions people unemployed. To support them, therefore, immense activities are activated in different sectors. Accordingly, increasing importance on NDT is given and in most cases particular application of Gamma radiography is preferred using Iridium Isotope Ir-192. Consequently the points of implications of isotopes are in Open Field and Inservice Inspection Radiography, Handling of Radiation Emergencies, Safe Transport of Radioactive Materials and Hazardous Effects and Risk of Ionizing Radiation, etc. Accordingly over exposure of Ir-192 Radionuclides, Accidents and Unusual Occurrences: Case Studies, Training Courses on Safety and Regulation of Sealed Sources, Licenses for Radiography Operation including Safe Disposal of Isotopes are the salient issues to be viewed in appropriate perspectives. The role played by Bangladesh Atomic Energy Commission and Bangladesh Society for NDT in collaboration with other members of the international committee for NDT are furthering the safe industrialization process

    Elder, Benjamin; Khoury, Justin; Haslinger, Philipp; Jaffe, Matt; Müller, Holger; Hamilton, Paul

    2016-08-01

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a three-dimensional nonlinear partial differential equation. This paper calculates the chameleonic force using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the partial differential equation to a one-dimensional ordinary differential equation. We examine the effects of approximations made in previous efforts on this subject and calculate the chameleonic force in a setup that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its offset from the center, and the effects of the chamber walls. Remarkably, the acceleration on a test atomic particle is found to differ by only 20% from the approximate analytical treatment. These results allow us to place rigorous constraints on the parameter space of chameleon field theories, although ultimately the constraint we find is the same as the one we reported in Hamilton et al. because we had slightly underestimated the size of the vacuum chamber. This computational technique will continue to be useful as experiments become even more precise and will also be a valuable tool in optimizing future searches for chameleon fields and related theories.

    2016-08-01

    In the present work we study the effect of unparticle modified static potentials on the energy levels of the hydrogen atom. By using Rayleigh-Schrödinger perturbation theory, we obtain the energy shift of the ground state and compare it with experimental data. Bounds on the unparticle energy scale ΛU as a function of the scaling dimension dU and the coupling constant λ are derived. We show that there exists a parameter region where bounds on ΛU are stringent, signaling that unparticles could be tested in atomic physics experiments.

    The energy and decay width of the pi-K atom are evaluated in the framework of the quasipotential-constraint theory approach. The main electromagnetic and isospin symmetry breaking corrections to the lowest-order formulas for the energy shift from the Coulomb binding energy and for the decay width are calculated. They are estimated to be of the order of a few per cent. We display formulas to extract the strong interaction S-wave pi-K scattering lengths from future experimental data concerning the pi-K atom.

  3. Basic plan of development and utilization of atomic energy, 1980

    International Nuclear Information System (INIS)

    The stable acquisition of energy is indispensable for the maintenance and improvement of national living standard and the development of social economy. The supply of oil tends to be tight in medium and long term perspective. Japan must acquire oil stably, save oil consumption as far as possible, and develop substitute energy. The development and utilization of atomic energy must be promoted as the most important subject in the energy policy because it is the most promising substitute energy. The nuclear power stations in operation in Japan are 21 plants with 15 million kW capacity, and it is equivalent to 12% of the total power generation. Adding the plants under construction and in preparation, the total becomes 35 plants and 28 million kW, but the construction is behind schedule due to the difficulty in the location of new power stations. As for the research and development on atomic energy, the establishment of nuclear fuel cycle such as the enrichment of uranium, the reprocessing of fuel and the treatment and disposal of radioactive wastes, the development of power reactors of new types, the research on nuclear fusion and so on have been endeavored. The maintenance of health of people and the preservation of environment are the prerequisities to the promotion of atomic energy. Japan contributes to form the new order on the basis of the results of INFCE. The development and utilization of atomic energy in 1980 are forwarded based on the basic policy described. (Kako, I.)

    A frequency stabilized laser referenced to an unperturbed atomic two level system acts as the most accurate clock with femtosecond clock ticks. For any meaningful use, a Femtosecond Laser Frequency Comb (FLFC) is used to transfer the atomic clock accuracy to electronically countable nanosecond clock ticks. Here we propose an alternative clockwork based on the phenomenon that when an atomic system is slowly evolved in a cyclic path, the atomic energy levels gather some phase called the geometric phase. This geometric phase dependent energy shift has been used here to couple the two frequency regimes in a phase coherent manner. It has also been shown that such a technique can be implemented experimentally, bypassing the highly involved setup of a FLFC.

  6. Non—conservation of energy arising from atomic dipole interactions and its effects on light field and coupled atoms

    DongChuan-Hua

    2003-01-01

    The interactions between coulpled atoms and a single mode of a quantized electromagnetic field, which involve the terms originating from the dipole interactions, are discussed. In the usual Jaynes-Cummings model for coupled atoms, the terms of non-conservation of energy originating from dipole interactions are neglected, however, we take them into consideration in this paper. The effects of these terms on the evolutions of quantum statistic properties and squeezing of the field, the squeezing of atomic dipole moments and atomic population inversion are investigated. It has been shown that the coupling between atoms modulates these evolutions of fields and atoms. The terms of non-conservation of energy affect these evolutions of field and atoms slightly. They also have effects on the squeezing of the field, the squeezing of atomic dipole and atomic population inversions. The initial states of atoms also affect these properties.

    Elder, Benjamin; Haslinger, Philipp; Jaffe, Matt; Müller, Holger; Hamilton, Paul

    2016-01-01

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a 3-dimensional nonlinear partial differential equation (PDE). In this paper, we introduce a new technique for calculating the chameleonic force, using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the PDE to a 1-dimensional ordinary differential equation (ODE). We examine the effects of approximations made in previous efforts on this subject, and calculate the chameleonic force in a set-up that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its o...

  9. Summoning earth and fire: The energy development implications of Grameen Shakti (GS) in Bangladesh

    International Nuclear Information System (INIS)

    Since its establishment in 1996, the nonprofit company Grameen Shakti (GS) has installed almost half a million solar home systems (SHS), 132,000 cookstoves, and 13,300 biogas plants among 3.1 million beneficiaries. They plan to ramp up their expansion so that by 2015, more than 1.5 million SHS are in place along with 100,000 biogas units and 5 million improved cookstoves. This article describes GS's current activities, the contours of its programs, and likely reasons for its success. It also explores the remaining challenges facing GS and distils common lessons for other energy development assistance projects and programs around the world. After detailing research methods consisting primarily of research interviews and site visits, the article briefly explores the history of GS and summarizes its three most prominent programs. The article then identifies six distinct benefits to their programs-expansion of energy access, less deforestation and fewer greenhouse gas emissions, price savings, direct employment and income generation, improved public health, and better technology-before discussing challenges related to staff retention and organizational growth, living standards, technical obstacles, affordability, tension with other energy programs, political constraints, and awareness and cultural values. -- Highlights: → Grameen Shakti (GS) has installed a large number of solar home systems (SHS), cookstoves, and biogas plants. → GS programs have brought a wide array of social and economic benefits. → GS programs face internal and external challenges if they are to remain successful.

  16. Bremsstrahlung spectra from atoms and ions at low relativistic energies

    International Nuclear Information System (INIS)

    Analytic expressions for bremsstrahlung spectra from neutral atoms and ions, including the polarizational bremsstrahlung contribution in a stripped atom approximation, are developed for electron scattering at energies of 10-2000 keV. A modified Elwert factor and a simple higher Born correction are used for the Coulomb spectrum, with ordinary bremsstrahlung screening effects in ions and atoms adequately characterized in the non-relativistic Born approximation. In parallel with the development of this analytic description, new numerical results are obtained for ordinary bremsstrahlung from ions and from bare nuclei, appreciably extending the available data set which can be used to study dependences on element, ionicity, energy and the fraction of incident energy radiated. The accuracy of predictions with the analytic expressions is then determined by comparison with the full numerical relativistic partial-wave results for ordinary bremsstrahlung and with non-relativistic numerical results in the Born approximation or in partial waves for the polarizational amplitude.

    1999-08-01

    The factors, by which the modern engineering ethics has been profoundly affected, were classified to three categories, namely mental blow, the destruction of human function and environment damage. The role of atomic energy engineering in the ethic field has been shown in the first place. It is pointed out that it has brought about the mental blow by the elucidation of universal truth and discipline and the functional disorder by the power supply. However, the direct effect of radiation to the human kinds is only a part of the stresses comparing to the accumulation of the social stress which should be taken into account of by the possibility of disaster and the suspicion of the atomic energy politics. An increase in the multiple stresses as well as the restriction of criticism will place obstacles on the promotion of atomic energy. (author)

    If dark energy --- which drives the accelerated expansion of the universe --- consists of a light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. Chameleon fields and other theories with screening mechanisms, however, can evade these tests by suppressing the forces in regions of high density, such as the laboratory. Using a cesium matter-wave interferometer near a spherical mass in an ultra-high vacu...

  5. Correlated energy transfer between two ultracold atomic species

    Science.gov (United States)

    Krönke, Sven; Knörzer, Johannes; Schmelcher, Peter

    2015-05-01

    We study a single atom as an open quantum system, which is initially prepared in a coherent state of low energy and oscillates in a one-dimensional harmonic trap through an interacting ensemble of NA bosons, held in a displaced trap [arXiv:1410.8676]. The non-equilibrium quantum dynamics of the total system is simulated by means of an ab-initio method, giving us access to all properties of the open system and its finite environment. In this talk, we focus on unraveling the interplay of energy exchange and correlations between the subsystems, which are coupled in such a spatio-temporally localized manner. We show that an inter-species interaction-induced level splitting accelerates the energy transfer between the atomic species for larger NA, which becomes less complete at the same time. System-environment correlations prove to be significant except for times when the excess energy distribution among the subsystems is highly imbalanced. These correlations result in incoherent energy transfer processes, which accelerate the early energy donation of the single atom. By analyzing correlations between intra-subsystem excitations, certain energy transfer channels are shown to be (dis-)favored depending on the instantaneous direction of transfer.

Serving 162 Member States, two more than the year before, the IAEA’s activities in 2014 focused on the following areas, in line with its mandate: • Nuclear Energy: The IAEA assisted Member States in the introduction of nuclear power programmes and in the efficient and safe use of nuclear energy, fostering innovation and building capability in energy planning, analysis, and nuclear information and knowledge management. • Nuclear Sciences and Applications: The IAEA continued to assist Member States in building, strengthening and maintaining capacities in the safe, peaceful and secure use of nuclear technology. • Nuclear Safety and Security: The IAEA and its Member States continued to strengthen nuclear safety worldwide, including through the implementation of the Action Plan on Nuclear Safety, which had been endorsed by the General Conference in 2011 after the accident at the Fukushima Daiichi nuclear power plant earlier that year. The IAEA also supported States, upon request, in their efforts to achieve effective security wherever nuclear and other radioactive materials are in use. • Nuclear Verification: The IAEA implemented safeguards in 180 States and as at the end of every year, it drew conclusions for each State for which safeguards were applied. • Technical Cooperation: The IAEA assisted Member States in their efforts to achieve the Millennium Development Goals and in preparation for the post-2015 Sustainable

  17. The World Power Conference and atomic energy

    International Nuclear Information System (INIS)

    The possibility that emerged after the last World War that useful power could be produced from nuclear fission led to optimistic estimates that nuclear power would prove to be the solution to the world's energy problems. The possible advantages of nuclear methods of power production compared with conventional means are discussed at the World Power Conference. The 1962 Conference with its theme 'The Changing Pattern of Power' will undoubtedly attract great interest in a world where the change-over from conventional to nuclear fuels for power production has started in some countries and is being actively examined in others. It is generally being realized that even though a country may possess indigenous supplies of uranium or thorium minerals, the building up of a nuclear industry i s a long and expensive process and the alternative of depending on countries more advanced in nuclear technology for the supply of materials, skill and know-how is costly in foreign exchange and international prestige. Many of the industrialized countries, still possessing supplies of conventional fuels, are preparing for the day when their reserves will become depleted and are embarking on training schemes to ensure a continuing supply of engineers and scientists skilled in nuclear arts

  2. Nuclear fuel cycles as reflected in the atomic energy laws

    International Nuclear Information System (INIS)

    The author measures the stations of the nuclear fuel cycles against the requirements laid down by the constitution and the Atomic Energy Act. All safety-relevant installations of the nuclear fuel cycles for LWR-type and FBR-type reactor stations are explained and defined in the first section of the book, stating facts and technical aspects including the capacity problems in connection with spent fuel management and the resulting need for interim storage facilities. The following sections on the legal aspects discuss the various installations in comparison to the legal requirements and definitions of the Atomic Energy Act. The author emphasizes the separation of competences for the determination of safety-relevant facts (natural sciences and engineering), and for weighting decisions on the required prevention of damage (state powers). The licensing requirements given in section 7, sub-sec. (2) Atomic Energy Act and their respective relationships are examined in detail. The lines of concretization emanating from section 7, sub-sec. (2), no. 3 Atomic Energy Act are followed up down to the lowest level of legislative powers, and essential deficits in the light of constitutional law are pointed out, together with suggestions for improvement. Within the frame of a constitutional interpretation of section 7, sub-sec. (2), no. 3 Atomic Energy Act, the author analyses the decisions of the Federal Constitutional Court concerning the protective obligations of the state and their validity with regard to future generations, showing that the Federal Constitutional Court applies higher safety standards than those currently used by the administrative bodies. On this basis, the author develops a national, arithmetical average of natural radiation burden to serve as a substantive criterion for determining the borderline between damage prevention and risk to be accepted.

    Because of the growing need of excitation cross-section data of atomic hydrogen by fully stripped heavy ions for the preparation of an atomic database for neutral-beam penetration in large tokamaks, we have calculated these data in the framework of the first-order Born approximation for n≤20 in the energy range of 0.1 to 1.5 MeV/amu. The present computed results are found to be in agreement with the existing observed results. From the present calculation it also appears that the contribution from subshells characterized by l>3 is always less than 2%

    2015-01-01

    Mutation breeders in the 1960s seemed poised to use atomic energy to speed up mutation rates in plants in order to develop new crop varieties, for the benefit of all people. Although skepticism had slowed this work in the United States, the International Atomic Energy Agency (IAEA) nurtured the scientific field, its community of experts, and an imagined version of the future that put humans in control of their destiny. The IAEA acted as a center of dissemination and support for experts and ideas even when they had fallen from favor elsewhere. Through the lens of the IAEA, plant breeding bore the appearance of a socially progressive, ultra-modern science destined to alleviate population pressures. Administrators at the IAEA also were desperate for success stories, hoping to highlight mutation plant breeding as a potential solution to the world's ills. The community of mutation plant breeders gained a lifeline from the consistent clarion call from the Vienna-based agency to use atomic energy to understand the natural world and quicken its pulse with radioisotopes.

    An assumptive theoretical relationship is suggested to describe the property of molecular atomization energy and energy transfer rate in the initiation of explosions. To investigate the relationship between atomization energy and energy transfer rate, the number of doorway modes of explosives is estimated by the theory of Dlott and Fayer in which the rate is proportional to the number of normal mode vibrations. It was evaluated frequencies of normal mode vibrations of eight molecules by means of density functional theory (DFT) at the b3p86/6-31G(d,p) level. It is found that the number of doorway modes shows a linear correlation to the atomization energies of the molecules, which were also calculated by means of the same method. A mechanism of this correlation is discussed. It is also noted that in those explosives with similar molecular structure and molecular weight, the correlation between the atomization energy and the number of doorway modes is higher.

    1998-01-01

    We present a study of parity (P) violating contributions to the eigenenergies of stationary systems containing atoms in spatially inhomogeneous external electric fields. In this context the subtle interplay of P-violation and time reversal (T) invariance plays an important role. If the entire field configuration is chosen to exhibit chirality the energies are in general shifted by pseudoscalar contributions which change sign under a planar reflection of the field. To calculate the effects we ...

  4. World situation of atomic energy and nuclear fuel cycle

    International Nuclear Information System (INIS)

    At the International Conference organized by the IAEA in May 1976, several sections dealt with problems of the production of atomic energy and of the nuclear fuel cycle. However, the whole spectrum of these problems was discussed including problems of economic policy, politics and ethical problems, too. Reports were presented on trends of the development of atomic energy in developed and developing countries. Besides the systems of nuclear power plants and the trends of their development, the Conference attached prominent importance to the supply of nuclear fuels and to the fuel cycle, respectively. Owing to important factors, the reprocessing of the spent nuclear fuel was emphasized. The problem area of the treatment of radioactive wastes, the protection of workers in immediate contact and of environment against radiations, the possibilities of ensuring nuclear safety, the degrees of hazards and the methods of protection of fast breeder reactors and up-to-date equipments were discussed. In contrast to earlier conferences the complex problem of the correlation of atomic energy to public opinion played an important role, too. (P.J.)

    1999-01-01

    The atomic energy power generation is recognized to be important to solve the problems of the competitive relations among the Asian developing countries due to the increasing dependency on the crude oil produced in the Middle East and the insecurity of transport route of the oil. The reorganization and inauguration of JNC(former PNC) has been carried out for the development of liquid metal reactor and related fuel cycle technology as the national development project to prevent the global green house effect and to continue the economic development. The construction of light water reactor, the utilization of plutonium in light water reactor and the enrichment and reprocessing of spent fuel of light water reactor are classified as proven technologies which will be covered by the industry. The government will lead to the environment favorable for introduction of the atomicenergy and will monitor the situation. The specifics of atomic energy development project and the development system for the 21th century will be contained in the long term atomic energy development plan which will be completed by 2000 and the reorganization operation has been initiated.

  6. Scattering of low-energy neutrinos on atomic shells

    International Nuclear Information System (INIS)

    We present a derivation of the total cross section for inelastic scattering of low-energy solar neutrinos and reactor antineutrinos on bound electrons, resulting in a transition of the electron to an excited state. The atomic-shell structure of various chemical elements is treated in terms of a nonrelativistic approximation. We estimate the interaction rates for modern neutrino detectors, in particular the Borexino and GEMMA experiments. We establish that in these experiments the effect can be safely neglected, but it could be accessible to future large-volume neutrino detectors with low energy threshold

  9. Regulations, Policies and Strategies for LLRW Management in Bangladesh - 12368

    International Nuclear Information System (INIS)

    Low level radioactive waste (LLW) is generated from various nuclear applications in Bangladesh. The major sources of radioactive waste in the country are at present: (a) the 3 MW TRIGA Mark-II research reactor; (b) the radioisotope production facility; (c) the medical, industrial and research facilities that use radionuclides; and (d) the industrial facility for processing monazite sands. Radioactive waste needs to be safely managed because it is potentially hazardous to human health and the environment. According to Nuclear Safety and Radiation Control Act-93, the Bangladesh Atomic Energy Commission (BAEC) is the governmental body responsible for the receipt and final disposal of radioactive wastes in the whole country. Waste management policy has become an important environmental, social, and economical issue for LLW in Bangladesh. Policy and strategies will serve as a basic guide for radioactive waste management in Bangladesh. The waste generator is responsible for on-site collection, conditioning and temporary storage of the waste arising from his practice. The Central Waste Processing and Storage Unit (CWPSU) of BAEC is the designated national facility with the requisite facility for the treatment, conditioning and storage of radioactive waste until a final disposal facility is established and becomes operational. The Regulatory Authority is responsible for the enforcement of compliance with provisions of the waste management regulation and other relevant requirements by the waste generator and the CWPSU. The objective of this paper is to present, in a concise form, basic information about the radioactive waste management infrastructure, regulations, policies and strategies including the total inventory of low level radioactive waste in the country. For improvement and strengthening in terms of operational capability, safety and security of RW including spent radioactive sources and overall security of the facility (CWPSF), the facility is expected to serve

  10. Atomic energy law in the Federal Republic of Germany

    International Nuclear Information System (INIS)

    Atomic Energy Law, presenting itself 18 years after the Atomic Law (AtG) having taken effect in the Federal Republic of Germany, has developed considerably during the past three years which was also due to the controversy between supporters and opponents of nuclear energy becoming more intensive. In order to gain their ends both parties refer to the AtG and expect both the executive and legislative power to follow their interpretation of the laws. The reason for this lies mainly in the latitude of evaluating and judging the criteria which the law has granted its users, especially the administrative authorities and the courts. Thus political and juridicial fundamental decisions in favour of the peaceful use of nuclear energy might be jeopardized. Therefore all ambignous passages of the law which can be detected by critically evaluating numerous and partly inconsistent decisions of courts, should be eliminated, in particular for reasons of its validity. Also, administration and court should be given concrete standards for rating the application of the law, especially for the assessment and acceptance of the risks rising from the peaceful use of nuclear energy.

  11. Energy distributions for ionization in ion-atom collisions

    CERN Document Server

    Amaya-Tapia, A

    2016-01-01

    In this paper we discuss how through the process of applying the Fourier transform to solutions of the Schr\\"odinger equation in the Close Coupling approach, good results for the ionization differential cross section in energy for electrons ejected in ion-atom collisions are obtained. The differential distributions are time dependent and through their time average, the comparison with experimental and theoretical data reported in the literature can be made. The procedure is illustrated with reasonable success in two systems, $p+H$ and $p+He$, and is expected to be extended without inherent difficulties to more complex systems. This allows advancing in the understanding of the calculation of ionization processes in ion-atom collisions.

  14. Atomic Oxygen Energy in Low Frequency Hyperthermal Plasma Ashers

    Science.gov (United States)

    Banks, Bruce A.; Miller, Sharon K R.; Kneubel, Christian A.

    2014-01-01

    Experimental and analytical analysis of the atomic oxygen erosion of pyrolytic graphite as well as Monte Carlo computational modeling of the erosion of Kapton H (DuPont, Wilmington, DE) polyimide was performed to determine the hyperthermal energy of low frequency (30 to 35 kHz) plasma ashers operating on air. It was concluded that hyperthermal energies in the range of 0.3 to 0.9 eV are produced in the low frequency air plasmas which results in texturing similar to that in low Earth orbit (LEO). Monte Carlo computational modeling also indicated that such low energy directed ions are fully capable of producing the experimentally observed textured surfaces in low frequency plasmas.

  15. Status of spent fuel in the 3MW BAEC MK-II research reactor facility of Bangladesh

    International Nuclear Information System (INIS)

    Bangladesh has been operating a 3 MW TRIGA MARK II research reactor since 1986. The reactor is installed in the campus of the Atomic Energy Research Establishment (AERE) at Savar, which is located about 40 km northwest of Dhaka. It is one of the main nuclear research facilities in the country. The reactor uses TRIGA LEU fuel with uranium content of 20% by weight. The enrichment level of the fuel is 19.7%. So far the reactor has been operated for 5624 hours with a total cumulative burnup (BU) of 10 690 MWh (445 MWd). The main areas of use are: training of man-power for research reactor operation and applications, radioisotope (RI) production, neutron activation analysis (NAA), neutron radiography (NR) and neutron scattering. Radioisotopes produced to date are: I-131, Sc-46 and Tc-99m. Bangladesh is a peace loving country with a strong commitment towards nuclear nonproliferation. Accordingly, it has signed several multilateral and bilateral agreements, protocols, treaties, etc. prevailing in the International Nuclear Non-proliferation regime. Bangladesh has also signed a Nuclear Cooperation Agreement with the USA on 17 September 1981, which facilitated export of nuclear technology from the USA to Bangladesh. The research reactor was procured under the provisions of this agreement. In 2003, the tenure of the Agreement was extended up to 2012. At present, there does not exist any spent fuel element in the reactor facility. However, with the recently undertaken RI production enhancement program, it is expected that the reactor will start generating spent fuels from the year 2012. It is to be mentioned that Bangladesh is aware of the US DOE's 'Take Back Program' in connection with the research reactor spent fuel of US origin, and is very much interested to take part in this program. The paper presents the current status of handling and storage facilities available for spent fuel and strategy for the safe management spent fuel to be generated from the research reactor in

  2. Low-energy scattering of electrons by atomic oxygen

    International Nuclear Information System (INIS)

    The method of polarized pseudostates has been used to calculate cross sections for the elastic scattering of electrons by atomic oxygen. These pseudostates are added to the close-coupling expansion to give a polarization potential in agreement with experimental values of polarizability. The resulting elastic cross sections are in good agreement with other theoretical calculations as well as with experiment for energies up to 10 eV. The reactance matrices obtained in this calculation have been used to calculate collision strengths for fine-structure transitions in the ground-state 3P term for electron temperatures above 5000 degree K

  3. The Atomic Energy of Canada Limited (AECL) employee health study

    International Nuclear Information System (INIS)

    A preliminary examination of records relating to past Chalk River employees provides some reassurance that large numbers of cancer deaths that might be related to occupational radiation exposure do not exist in the groups of employees studied to the end of 1982. The lack of reliable information on deaths of ex-employees who left AECL for other employment prevented the inclusion of this group in this preliminary study. This information will presumably be obtained during the course of the more comprehensive Atomic Energy of Canada Ltd. employee health study. 6 refs

    Britain was the first country to exploit atomic energy on a large scale, and at its peak in the mid-1960s, it had generated more electricity from nuclear power than the rest of the world combined.The civil atomic energy programme grew out of the military programme which produced plutonium for atomic weapons. In 1956, Calder Hall power station was opened by the Queen. The very next year, one of the early Windscale reactors caught fire and the world's first major nuclear accident occurred.The civil programme ran into further difficulty in the mid-1960s and as a consequence of procrastination in

    If dark energy, which drives the accelerated expansion of the universe, consists of a light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. Chameleon fields and other theories with screening mechanisms, however, can evade these tests by suppressing the forces in regions of high density, such as the laboratory. Using a cesium matter-wave interferometer near a spherical mass in an ultrahigh-vacuum chamber, we reduced the screening mechanism by probing the field with individual atoms rather than with bulk matter. We thereby constrained a wide class of dark energy theories, including a range of chameleon and other theories that reproduce the observed cosmic acceleration. PMID:26293958

    We performed embedded atom method calculations on surface energies and unstable stacking fault energies for a series of intermetallics for which interatomic potentials of the embedded atom type have recently been developed. These results were analyzed and applied to the prediction of relative ductility of these materials using the various current theories. Series of alloys with the B2 ordered structure were studied, and the results were compared to those in pure body-centered cubic (bcc) Fe. Ordered compounds with L1{sub 2} and L1{sub 0} structures based on the face-centered cubic (fcc) lattice were also studied. It was found that there is a correlation between the values of the antiphase boundary (APB) energies in B2 alloys and their unstackable stacking fault energies. Materials with higher APB energies tend to have higher unstable stacking fault energies, leading to an increased tendency to brittle fracture. {copyright} {ital 1997 Materials Research Society.}

  17. Spent Fuel Management Program in the 3MW TRIGA MARK-II Research Reactor of Bangladesh

    International Nuclear Information System (INIS)

    Bangladesh Atomic Energy Commission (BAEC) has been operating a 3 MW TRIGA MARK II research reactor since 1986. The reactor was installed in the campus of the Atomic Energy Research Establishment (AERE) at Savar, Dhaka. It is one of the main nuclear research facilities in the country. The reactor uses TRIGA LEU fuel with uranium content of 20% by weight. The enrichment level of the fuel is 19.7%. The reactor has so far been operated for 7834 hours with a total cumulative burn up of 15898 MWh (662.5 MWd). The total burn up life of the present core is 1200 MWd. The main areas of use are: training of man-power for nuclear power plant applications, radioisotope (RI) production, neutron activation analysis (NAA), neutron radiography (NR) and neutron scattering. The government of Bangladesh has taken decision to establish nuclear power programme in the country. There is an ADP (Annual Development Project) to accomplish necessary activities for construction of medium size nuclear power plant (NPP) in the western zone of the country. Now, with regard to the safe management, storage of spent fuel and disposal of radioactive waste arising from operation of the research reactor and also from the proposed NPP expected to be constructed in future, BAEC is drawing up short and long-term plans and programs. At present, there does not exist any spent fuel element in the reactor facility. It is to be mentioned that Bangladesh is aware of the US DOE’s ‘Take Back Program’ in connection with the research reactor spent fuel of US origin, and is very much interested to take part in this program. The paper presents the current status of handling and storage facilities available for spent fuel and strategy for the safe management of spent fuel to be generated from the research reactor in near future.

  18. Upgradation of nuclear medical equipment in the developing countries and its impact in Bangladesh

    International Nuclear Information System (INIS)

    Bangladesh has thirteen Nuclear Medical Centres and one Institute of Nuclear Medicine in the country which are being run and maintained by the physicians scientists and engineers of Bangladesh Atomic Energy Commission. The peaceful application of atomic energy was initiated through all these Centres with the use of clinical isotopes for thyroid and kidney studies. The equipment used for these purposes were the thyroid uptake system, rectilinear scanner and the multiprobe renogram system. The first gamma camera was installed in the country in 1980 at the Institute of Nuclear Medicine, Dhaka. That was the turning point for the country in the field of nuclear medicine. Presently all the nuclear medical establishments are equipped least with a gamma camera, thyroid uptake system and a renogram system. In the last two decades there has been a tremendous development in the design of nuclear medical equipment. Most of the old equipments were slow and manually operated. In the beginning of nineties of the past century there was an uprising in the computer technology and most of the manually operated machines were brought under computerization. It was basically done with a custom built processor to perform only the specific job and spare the users from doing some extra manual work. But the performances of the recent models of the same computerized equipment are by far the best as compared with the past ones. This report describes the role of the IAEA in the upgradation of medical equipment, PC interfacing, upgrading of old gamma cameras and the technological and socio-economic impact in Bangladesh

  19. Experience and challenges on safeguards practices and approaches for BAEC 3 MW TRIGA Mk-II research reactor and other establishment of Bangladesh

    International Nuclear Information System (INIS)

    Bangladesh is deeply committed to nuclear non-proliferation signing and accesses to different unilateral protocols, agreements and treaties like Nuclear Non-Proliferation Treaty (NPT), Comprehensive Test Ban Treaty (CTBT), Safeguards Agreements, Nuclear Cooperation Agreements with the USA and other countries etc. are the manifestations of such commitment. The first of such agreements, the NPT was signed in August 1979. NPT is a national commitment that the signatory country will not engage in activities related on nuclear detonations. Subsequently a bilateral agreement entitled 'Safeguards Agreements' was signed with the International Atomic Energy Agency (IAEA) in June 1982. This provides for international verification of facilities and balancing of nuclear materials. 3MW TRIGA Mark-II Research Reactor Facility of Bangladesh Atomic Energy Commission (BAEC) is inspected physically by the IAEA Safeguards Inspectors on an annual basis. For this purpose, a subsidiary arrangement was made with the IAEA, which had defined the scope of such verification. Bangladesh has also signed a Nuclear Cooperation Agreement with the USA on September 17, 1981, which facilitated export of nuclear technology from USA to Bangladesh. Bangladesh also signed another bilateral agreement entitled 'Protocol Additional to the Safeguards Agreements' with the IAEA in March 30, 2001. The main purpose of this agreement is to provide the IAEA with information on 'so called dual-purpose materials and facilities' including the front end and back end of the nuclear fuel cycle. Its enforcement required filing of an initial declaration, draft of which has been sent to the Ministry of Science, Information and Communication Technology (MOSICT) for approval and transmittal to IAEA through the office of the permanent mission in Geneva. This protocol till to-date is the highest level of verification under the nonproliferation regime. The commitment of Bangladesh to non-proliferation is adequately reflected

    The detection of energetic neutral atoms allows for the remote examination of the interactions between plasmas and neutral populations in space. Before these neutral atoms can be measured, they must first be converted to ions. For the low energy end of this spectrum, interaction with a conversion surface is often the most efficient method to convert neutrals into ions. It is generally thought that the most efficient surfaces are low work functions materials. However, by their very nature, these surfaces are highly reactive and unstable, and therefore are not suitable for space missions where conditions cannot be controlled as they are in a laboratory. We therefore are looking to optimize a stable surface for conversion efficiency. Conversion efficiency can be increased either by changing the incident angle of the neutral particles to be grazing incidence and using stable surfaces with high conversion efficiencies. We have examined how to increase the angle of incidence from -80 degrees to -89 degrees, while maintaining or improving the total active conversion surface area without increasing the overall volume of the instrument. We are developing a method to micro-machine silicon, which will reduce the volume to surface area ratio by a factor of 60. We have also examined the material properties that affect the conversion efficiency of the surface for stable surfaces. Some of the parameters we have examined are work function, smoothness, and bond structure. We find that for stable surfaces, the most important property is the smoothness of the surface.

    The MidSTAR-2 satellite, to be built at the US Naval Academy as a follow-on to the successful MidSTAR-1 satellite, will launch in 2011 and carry three Goddard Space Flight Center (GSFC) experiments developed under Goddard's Internal Research and Development (IRAD) program. One of these GSFC instruments, the Miniature Imager for Neutral Ionospheric atoms and Magnetospheric Electrons (MINI-ME) builds on the heritage of the Goddard-developed Low-Energy Neutral Atom (LENA) imager launched on the IMAGE spacecraft in 2000. MINI- ME features a Venetian-blind conversion surface assembly that improves both light rejection and conversion efficiency in a smaller and lighter package than LENA making this an highly effective instrument for viewing solar wind charge exchange with terrestrial and planetary exospheres. We will describe the MINI-ME prototyping effort and its science targets, also including time variability of ENA fluxes and charge-exchange interactions in the upper atmosphere from the terrestrial ring current source.

  8. Atomic Physics in the Quest for Fusion Energy and ITER

    Energy Technology Data Exchange (ETDEWEB)

    Charles H. Skinner

    2008-02-27

    The urgent quest for new energy sources has led developed countries, representing over half of the world population, to collaborate on demonstrating the scientific and technological feasibility of magnetic fusion through the construction and operation of ITER. Data on high-Z ions will be important in this quest. Tungsten plasma facing components have the necessary low erosion rates and low tritium retention but the high radiative efficiency of tungsten ions leads to stringent restrictions on the concentration of tungsten ions in the burning plasma. The influx of tungsten to the burning plasma will need to be diagnosed, understood and stringently controlled. Expanded knowledge of the atomic physics of neutral and ionized tungsten will be important to monitor impurity influxes and derive tungsten concentrations. Also, inert gases such as argon and xenon will be used to dissipate the heat flux flowing to the divertor. This article will summarize the spectroscopic diagnostics planned for ITER and outline areas where additional data is needed.

  9. Atomic Energy of Canada Limited annual report 1989-1990

    International Nuclear Information System (INIS)

    In 1990, after a comprehensive industry review, the Canadian government announced that steps would be taken to revitalize the nuclear industry. Canada's nuclear utilities made a commitment to bear a large share of the cost of nuclear research and development. Atomic Energy of Canada Limited (AECL) reported its first financial loss in twelve years, as anticipated at the start of the year. Four of the 20 CANDU reactors operating worldwide were in the top ten based on lifetime performance. By year-end one foreign and two domestic utilities had announced their intention to build more CANDU units. The federal government has agreed to stabilize AECL's research funding at 1989-90 levels ($31.5 million above levels planned in 1985), has authorized AECL to negotiate with New Brunswick to build Point Lepreau-2 as the prototype for the CANDU-3 reactor, and has allowed the restructuring of AECL so utility and private sector investors can become equity partners in AECL CANDU

There are four stages in the licensing procedure before a Mine-Mill Facility Operating Licence is issued: exploration requires an underground exploration permit; site approval is needed before the start of the development stage; development approval is required before the construction of the mill and waste management facilities and depends on the information in a preliminary safety report; the granting of a final operating licence occurs after the Board is satisfied with the final safety report, operating policies and principles, tailings management, and decommissioning plans. The Board has resource management policies designed to ensure that uranium reserves are available to meet Canada's needs. The administration of safeguards is also the Board's responsibility. (LL)

  15. Higher Ionization Energies of Atoms in Density Functional Theory

    CERN Document Server

    Argaman, Uri; Kraisler, Eli

    2014-01-01

    Density functional theory (DFT) is an exact alternative formulation of quantum mechanics, in which it is possible to calculate the total energy, the spin and the charge density of many-electron systems in the ground state. In practice, it is necessary to use uncontrolled approximations that can mainly be verified against experimental data. Atoms and ions are simple systems, where the approximations of DFT can be easily tested. We have calculated within DFT the total energies, spin and higher ionization energies of all the ions of elements with 1 $\\leq$ Z $\\leq$ 29. We find the calculations in close agreement with experiment, with an error of typically less than ca. 1% for 1 $\\leq$ Z $\\leq$ 29. Surprisingly, the error depends on the electronic configuration of the ion in both local spin density approximation (LSDA) and Perdew-Burke-Ernzerhof general gradient approximation (PBE-GGA) and independent of both self-interaction correction (SIC) and relativistic corrections. Larger errors are found for systems in whi...

  16. Modeling and forecasting natural gas demand in Bangladesh

    International Nuclear Information System (INIS)

    Natural gas is the major indigenous source of energy in Bangladesh and accounts for almost one-half of all primary energy used in the country. Per capita and total energy use in Bangladesh is still very small, and it is important to understand how energy, and natural gas demand will evolve in the future. We develop a dynamic econometric model to understand the natural gas demand in Bangladesh, both in the national level, and also for a few sub-sectors. Our demand model shows large long run income elasticity - around 1.5 - for aggregate demand for natural gas. Forecasts into the future also show a larger demand in the future than predicted by various national and multilateral organizations. Even then, it is possible that our forecasts could still be at the lower end of the future energy demand. Price response was statistically not different from zero, indicating that prices are possibly too low and that there is a large suppressed demand for natural gas in the country. - Highlights: → Natural gas demand is modeled using dynamic econometric methods, first of its kind in Bangladesh. → Income elasticity for aggregate natural gas demand in Bangladesh is large-around 1.5. → Demand is price insensitive, indicating too low prices and/or presence of large suppressed demand. → Demand forecasts reveal large divergence from previous estimates, which is important for planning. → Attempts to model demand for end-use sectors were successful only for the industrial sector.

  17. Change of Energy of the Cubic Subnanocluster of Iron Under Influence of Interstitial and Substitutional Atoms.

    Nedolya, Anatoliy V; Bondarenko, Natalya V

    2016-12-01

    Energy change of an iron face-centred cubic subnanocluster was evaluated using molecular mechanics method depending on the position of a carbon interstitial atom and substitutional atoms of nickel. Calculations of all possible positions of impurity atoms show that the energy change of the system are discrete and at certain positions of the atoms are close to continuous.In terms of energy, when all impurity atoms are on the same edge of an atomic cluster, their positions are more advantageous. The presence of nickel atoms on the edge of a cubic cluster resulted in decrease of potential barrier for a carbon atom and decrease in energy in the whole cluster. A similar drift of a carbon atom from central octahedral interstitial site to the surface in the direction occurred under the influence of surface factors.Such configuration corresponds to decreasing symmetry and increasing the number of possible energy states of a subnanocluster, and it corresponds to the condition of spontaneous crystallization process in an isolated system.Taking into account accidental positions of the nickel atom in the iron cluster, such behaviour of the carbon atom can explain the mechanism of growth of a new phase and formation of new clusters in the presence of other kind of atoms because of surface influence.

    1990-01-01

    The reaction efficiency of several polymeric materials with thermal-energy (0.04 eV translational energy), ground-state (O3P) oxygen atoms was determined by exposing the materials to a room temperature gas containing a known concentration of atomic oxygen. The reaction efficiency measurements were conducted in two flowing afterglow systems of different configuration. Atomic oxygen concentration measurements, flow, transport and surface dose analysis is presented in this paper. The measured reaction efficiencies of Kapton, Mylar, polyethylene, D4-polyethylene and Tedlar are .001 to .0001 those determined with high-energy ground-state oxygen atoms in low earth orbit or in a high-velocity atom beam. D4-polyethylene exhibits a large kinetic isotope effect with atomic oxygen at thermal but not hyperthermal atom energies.

  7. Atomic energy law after the opt-out. Alive and fascinating. Report about the 14th German atomic energy law symposium 2012

    International Nuclear Information System (INIS)

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14th German Atomic Energy Law Symposium held in Berlin on November 19-20, 2012. Under the scientific chairmanship of Professor Dr. Martin Burgi, Ludwig Maximilian University of Munich, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), after an interruption of 5 years, again organized a scientific conference about practice-related topics of atomic energy and radiation protection law. Atomic energy law once again proved to be a reference area for sophisticated issues of constitutional law and administrative law above and beyond its technical confines. The agenda of the 14th German Atomic Energy Law Symposium featured a broad spectrum of topics ranging from backfitting of nuclear power plants to European atomic energy and radiation protection law, to challenges facing national legal systems in the execution of atomic energy law, to legal issues connected with decommissioning and waste management, and on to the topical subject of finding a repository site. The 14th German Atomic Energy Law Symposium, on the whole, again demonstrated that an open discourse between science and practice is able to furnish important contributions to the implementation of laws in a balanced way rooted in practice. Especially the contributions dealing with the independence of public authorities and their organization, the doctrine of the reservation of functions of the executive branch, and planning by laws contain additional provisions able to influence the continued development of administrative law also above and beyond atomic energy law. The BMU also referred to a decision just heard from Brussels to the effect that a new European Safety Directive would be published as early as in 2013. As a consequence of the nuclear stress tests conducted EU-wide, the Directive is to lay down provisions about transparency, material

    Visible emission spectra were acquired from neutral atoms sputtered by 35–60 keV Kr{sup +} ions from a polycrystalline tungsten surface. Mean velocities of excited tungsten atoms in seven different 6p states were also obtained via the dependence of photon intensities on the distance from the surface. The average velocities parallel to the surface normal varied by factors of 2–4 for atoms in the different 6p energy levels. However, they were almost independent of the incident ion kinetic energy. The 6p-level energy dependence indicated that the velocities of the excited atoms were determined by inelastic processes that involve resonant charge exchange.

    2011-01-01

    We introduce a machine learning model to predict atomization energies of a diverse set of organic molecules, based on nuclear charges and atomic positions only. The problem of solving the molecular Schr\\"odinger equation is mapped onto a non-linear statistical regression problem of reduced complexity. Regression models are trained on and compared to atomization energies computed with hybrid density-functional theory. Cross-validation over more than seven thousand small organic molecules yields a mean absolute error of ~10 kcal/mol. Applicability is demonstrated for the prediction of molecular atomization potential energy curves.

    Canada has been a leader in tritium handling technologies as a result of the successful CANDU reactor technology used for power production. Over the last 50 to 60 years, capabilities have been established in tritium handling and tritium management in CANDU stations, tritium removal processes for heavy and light water, tritium measurement and monitoring, and understanding the effects of tritium on the environment. This paper outlines details of tritium-related work currently being carried out at Atomic Energy of Canada Limited (AECL). It concerns the CECE (Combined Electrolysis and Catalytic Exchange) process for detritiation, tritium-compatible electrolysers, tritium permeation studies, and tritium powered batteries. It is worth noting that AECL offers a Tritium Safe-Handling Course to national and international participants, the course is a mixture of classroom sessions and hands-on practical exercises. The expertise and facilities available at AECL is ready to address technological needs of nuclear fusion and next-generation nuclear fission reactors related to tritium handling and related issues.

    2016-07-01

    The fabrication of porous nanocomposites is key to the advancement of energy conversion and storage devices that interface with electrolytes. Bismuth vanadate, BiVO4 , is a promising oxide for solar water splitting where the controlled fabrication of BiVO4 layers within porous, conducting scaffolds has remained a challenge. Here, the atomic layer deposition of bismuth vanadates is reported from BiPh3 , vanadium(V) oxytriisopropoxide, and water. The resulting films have tunable stoichiometry and may be crystallized to form the photoactive scheelite structure of BiVO4 . A selective etching process was used with vanadium-rich depositions to enable the synthesis of phase-pure BiVO4 after spinodal decomposition. BiVO4 thin films were measured for photoelectrochemical performance under AM 1.5 illumination. The average photocurrents were 1.17 mA cm(-2) at 1.23 V versus the reversible hydrogen electrode using a hole-scavenging sulfite electrolyte. The capability to deposit conformal bismuth vanadates will enable a new generation of nanocomposite architectures for solar water splitting. PMID:27246652

    Barklem, Paul S

    2016-01-01

    A theoretical method for the estimation of cross sections and rates for excitation and charge transfer processes in low-energy hydrogen atom collisions with neutral atoms, based on an asymptotic two-electron model of ionic-covalent interactions in the neutral atom-hydrogen atom system, is presented. The calculation of potentials and non-adiabatic radial couplings using the method is demonstrated. The potentials are used together with the multi-channel Landau-Zener model to calculate cross sections and rate coefficients. The main feature of the method is that it employs asymptotically exact atomic wavefunctions, which can be determined from known atomic parameters. The method is applied to Li+H, Na+H, and Mg+H collisions, and the results compare well with existing detailed full-quantum calculations. The method is applied to the astrophysically important problem of Ca+H collisions, and rate coefficients are calculated for temperatures in the range 1000-20000 K.

    Rabies is a major public health problem in Bangladesh, where most of the population live in rural areas. However, there is little epidemiological information on rabies in rural Bangladesh. This study was conducted in 30 upazilas (subdistricts) covering all six divisions of the country, to determine the levels of rabies and animal bites in Bangladesh. The total population of these upazilas was 6 992 302. A pretested questionnaire was used and data were collected by interviewing the adult members of families. We estimated that in Bangladesh, 166 590 [95% confidence interval (CI) 163 350-170 550] people per year are bitten by an animal. The annual incidence of rabies deaths in Bangladesh was estimated to be 1·40 (95% CI 1·05-1·78)/100 000 population. By extrapolating this, we estimated that 2100 (95% CI 1575-2670) people die annually from rabies in Bangladesh. More than three-quarters of rabies patients died at home. This community-based study provides new information on rabies epidemiology in Bangladesh.

    We analyze the electronic structure of atoms in the first, second and third periods using the electronic kinetic energy density and stress tensor density, which are local quantities motivated by quantum field theoretic consideration, specifically the rigged quantum electrodynamics. We compute the zero surfaces of the electronic kinetic energy density, which we call the electronic interfaces, of the atoms. We find that their sizes exhibit clear periodicity and are comparable to the conventional atomic and ionic radii. We also compute the electronic stress tensor density and its divergence, tension density, of the atoms, and discuss how their electronic structures are characterized by them.

    The structure of the rate of variation of the atomic energy for an arbitrary stationary motion of the atom in interaction with a quantum electromagnetic field is investigated. Our main purpose is to rewrite the formalism in Zhu et al. (Phys Rev D 73:107501, 2006) and to deduce the general expressions of the Einstein A coefficients of an atom on an arbitrary stationary trajectory. The total rate of change of the energy and Einstein coefficients of the atom near a plate with finite temperature or acceleration are also investigated.

    We have calculated the energy spectra of one- and two-electron atoms (ions) centered in an impenetrable spherical box by variational method with B-splines as basis functions. Accurate results are obtained for both large and small radii of confinement. The critical box radius of confined hydrogen atom is also calculated to show the usefulness of our method. A partial energy degeneracy in confined hydrogen atom is found when the radius of spherical box is equal to the distance at which a node of single-node wavefunctions of free hydrogen atom is located.

Nuclear materials to be discussed here include: - Both natural and enriched uranium for research; - Imported enriched nuclear fuel elements for JRR-2 (10-MW CP-5), JRR-4 (1-MW swimming pool), JPDR (12.5-MW(e) BWR), and the critical assemblies for JMTR (50-MW light-water moderated) and for the propulsion reactor; - Domestically-fabricated natural uranium fuel elements for JRR-3 (10-MW heavy-water moderated); - Domestically-fabricated fuels for the critical assemblies manufactured from imported enriched uranium oxides; - Domestically-fabricated enriched fuel elements for JPDR and for the propulsion reactor manufactured from imported enriched uranium hexafluoride. Both thorium and plutonium are also under control, but excluded from the present paper. Entire administrative pattern for nuclear material control is first presented. The emphasis is placed on the domestic fabrication of enriched fuel elements from imported enriched uranium, and the details of the control procedures during and after the fabrication process are discussed. The control procedures include the chemical analysis for purity check, isotopic assay by mass spectrometry, physical and mechanical tests of fabricated products, and the careful prevention in the diversion of nuclear materials. Administrative problems being attributed to Japanese domestic situation are presented; for example, the segregation, collection and efficient recovery and practical uses of residual uranium from the fabrication process. Methods for keeping records on the storage and uses of nuclear materials are also discussed. More satisfactory control procedures for other nuclear materials such as thorium and heavy water are under progress. (author)

  3. The International Atomic Energy Agency Nuclear Security Education Strategies

    International Nuclear Information System (INIS)

    The threat of nuclear terrorism has not diminished. In response to the concerns of States, an international nuclear security framework has emerged through the establishment of a number of legally binding and non-binding international instruments which obligates or commits States to carry out a number of actions to protect against nuclear terrorism. In this context, the need for human resource development programmes in nuclear security was underscored at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors' Meetings. In the pursuit of this need, the IAEA provides a comprehensive nuclear security training programme to States on a regular basis, and has developed a concept that seeks to effectively pass ownership of nuclear security knowledge and skills to States through the establishment of a Nuclear Security Support Centre. In addition, the IAEA has developed a technical guidance titled IAEA Nuclear Security Series No. 12 - Educational Programme in Nuclear Security that consists of a model of a Master of Science (M.Sc.) and assists educational institutions to provide nuclear security education. The article sets out IAEA efforts in the area of nuclear security training and education, including the assistance to States for establishing a Nuclear Security Support Centre. It underlines the objective and content of the IAEA Nuclear Security Series No. 12, discusses different concepts on how to establish nuclear security at universities and, emphasizes on the IAEA efforts to assist educational and research institutions, and other stake holders to enhance global nuclear security by developing, sharing and promoting excellence in nuclear security education.

    International Nuclear Information System (INIS)

    One of the objectives of the reorganization process of Argentina's public sector was to transfer to the private sector some of the Nation's productive activities, including those concerning the nuclear field. As a consequence, by Decree No. 1540 of August 30, 1994, (B.O. 2-Dec-94), CNEA's functions were partially reorganized. According to Decree No. 1540, the National Atomic Energy Commission (CNEA) maintained the missions and functions established by Decree-Law No. 22.498/56, with the exception of the regulation and surveillance of nuclear activities and the nuclear power generation activities. For the fulfillment of these activities, both the National Board of Nuclear Regulation (Ente Nacional Regulador Nuclear - ENREN) and Nucleoelectrica Argentina S.A. (NASA), were created.

    Full Text Available The size optimization and economic evaluation of the solar-wind hybrid renewable energy system (RES to meet the electricity demand of 276 kWh/day with 40 kW peak load have been determined in this study. The load data has been collected from the motels situated in the coastal areas of Patenga, Chittagong. RES in standalone as well as grid connected mode have been considered. The optimal system configurations have been determined based on systems net present cost (NPC and cost of per unit energy (COE. A standalone solar-wind-battery hybrid system is feasible and economically comparable to the present cost of diesel based power plant if 8% annual capacity shortage is allowed. Grid tied solar-wind hybrid system, where more than 70% electricity contribution is from RES, is economically comparable to present grid electricity price. Moreover, grid tied RES results in more than 60% reduction in greenhouse gases emission compared to the conventional grid. Sensitivity analysis has been performed in this study to determine the effect of capital cost variation or renewable resources variation on the system economy. Simulation result of sensitivity analysis has showed that 20% reduction of installation cost results in nearly 9%–12% reductions in cost of per unit energy.

  6. Challenges of atomic energy regulation in Indian context

    International Nuclear Information System (INIS)

    Over the years, India has mastered all the stages of the nuclear fuel cycle, which include mining, processing and fabrication of nuclear fuel; design, construction, and operation of nuclear power reactors and research reactors; reprocessing of spent fuel and management of radioactive wastes. Ionising radiation is also used widely in medical, industrial and research areas. Since its inception, Department of Atomic Energy (DAE) was enforcing radiological safety in the country through in-house or ad-hoc committees, till a dedicated regulatory body (AERB) was set up 25 years ago. Today India is operating 19 nuclear power plants with different vintages (2 BWRs and 17 PHWRs) and another 8 (1 PFBR, 5 PHWRs and 2 PWRs) are in various stages of construction. Recently there are new evolutionary reactors (AHWRs) for which design has been completed and are on the threshold for consideration for construction. To match the rapid growth in the need for power India is also about to take up construction of large evolutionary PWRs of foreign design. This variety in the Indian nuclear power programme has come up due to a systematic evaluation and optimisation of the resources and technology available within the country. Added to this is the growing use of radiation in non-power applications. As the safety supervision of this huge programme is the responsibility of AERB, it faces various challenges, like, - Strategies for regulating wide variety of nuclear and radiation facilities with wide dispersal; - Meeting present day expectations with regard to nuclear and radiation safety and nuclear security; - The safety and security of large number of radioactive sources spread over such a vast country and of the associated import/export guidance; - Ensuring safety of old plants by periodic reviews and by prescribing adequate safety upgradation and ageing management programme; -Adaptation of the regulatory system and of regulations to new and foreign design nuclear technologies and

    Light elements such as alkali metal (lithium, sodium) or halogen (fluorine, chlorine) are present in various substances and indeed play significant roles in our life. Although atomic behaviours of these elements are often a key to resolve chemical or biological activities, they are hardly visible in transmission electron microscope because of their smaller scattering power and higher knock-on probability. Here we propose a concept for detecting light atoms encaged in a nanospace by means of e...

  11. The environment associated with significant tornadoes in Bangladesh

    Science.gov (United States)

    Bikos, Dan; Finch, Jonathan; Case, Jonathan L.

    2016-01-01

    This paper investigates the environmental parameters favoring significant tornadoes in Bangladesh through a simulation of ten high-impact events. A climatological perspective is first presented on classifying significant tornadoes in Bangladesh, noting the challenges since reports of tornadoes are not documented in a formal manner. The statistical relationship between United States and Bangladesh tornado-related deaths suggests that significant tornadoes do occur in Bangladesh so this paper identifies the most significant tornadic events and analyzes the environmental conditions associated with these events. Given the scarcity of observational data to assess the near-storm environment in this region, high-resolution (3-km horizontal grid spacing) numerical weather prediction simulations are performed for events identified to be associated with a significant tornado. In comparison to similar events over the United States, significant tornado environments in Bangladesh are characterized by relatively high convective available potential energy, sufficient deep-layer vertical shear, and a propensity for deviant (i.e., well to the right of the mean flow) storm motion along a low-level convergence boundary.

  13. Resonance interaction energy between two accelerated identical atoms in a coaccelerated frame and the Unruh effect

    Zhou, Wenting; Rizzuto, Lucia

    2016-01-01

    We investigate the resonance interaction energy between two uniformly accelerated identical atoms, interacting with the scalar field or the electromagnetic field in the vacuum state, in the reference frame coaccelerating with the atoms. We assume that one atom is excited and the other in the ground state, and that they are prepared in their correlated symmetric or antisymmetric state. Using perturbation theory, we separate, at the second order in the atom-field coupling, the contributions of vacuum fluctuations and radiation reaction field to the energy shift of the interacting system. We show that only the radiation reaction term contributes to the resonance interaction between the two atoms, while Unruh thermal fluctuations, related to the vacuum fluctuations contribution, do not affect the resonance interatomic interaction. We also show that the resonance interaction between two uniformly accelerated atoms, recently investigated in the comoving (locally inertial) frame, can be recovered in the coaccelerate...

    Energy Technology Data Exchange (ETDEWEB)

    Toomey, Christopher; Wyse, Evan T.; Kurzrok, Andrew J.; Swarthout, Jordan M.

    2012-09-04

    Since 1957, the International Atomic Energy Agency (IAEA) has worked to ensure the safe and responsible promotion of nuclear technology throughout the world. The IAEA operates at the intersection of the Nuclear Nonproliferation Treaty’s (NPT) fourth and third articles, which guarantee Parties to the Treaty the right to peaceful uses of nuclear technology, provided those activities are placed under safeguards verified by the IAEA. However, while the IAEA has enjoyed substantial success and prestige in the international community, there is a concern that its resources are being stretched to a point where it may no longer be possible to execute its multifaceted mission in its entirety. As noted by the Director General (DG) in 2008, demographics suggest that every aspect of the IAEA’s operations will be in higher demand due to increasing reliance on non-carbon-based energy and the concomitant nonproliferation, safety, and security risks that growth entails. In addition to these nuclear energy concerns, the demand for technical developmental assistance in the fields of food security, resource conservation, and human health is also predicted to increase as the rest of the world develops. Even with a 100% value-for-money rating by the U.S. Office of Management and Budget (OMB) and being described as an “extraordinary bargain” by the United Nations Secretary-General’s High-level Panel on Threats, Challenges and Change, real budget growth at the Agency has been limited to zero-real growth for a better part of the last two decades. Although the 2012 regular budget (RB) received a small increase for most programs, the 2013 RB has been set at zero-real growth. As a result, the IAEA has had to defer infrastructure investments, which has hindered its ability to provide the public goods its Members seek, decreased global security and development opportunities, and functionally transformed the IAEA into a charity, dependent on extrabudgetary (EB) contributions to sustain

    The spectra of excited lithium-7 atoms prepared in a magneto-optical trap are studied using a UV laser. The laser diagnostics of the energy of Rydberg atoms is developed based on measurements of the change in resonance fluorescence intensity of ultracold atoms as the exciting UV radiation frequency passes through the Rydberg transition frequency. The energies of various nS configurations are obtained in a broad range of the principal quantum number n from 38 to 165. The values of the quantum defect and ionization energy obtained in experiments and predicted theoretically are discussed.

  17. ''Further precaution'' in Atomic Energy Law? On unconstitutionality of paragraph 7d AtG

    International Nuclear Information System (INIS)

    On 1st January 2011 the new paragraph 7d of the Atomic Energy Act became operative with the 12th Modification Law according to the Atomic Energy Law. This new paragraph introduces a new category of the nuclear-legal prevention of damage. The contribution under consideration examines how this new regulation for further precautionary actions against risks is to be understood within the existing regulations for permission and retrofitting of nuclear power plants and within the acknowledged dogmatics of the Atomic Energy Act. In addition it is examined whether this understanding of the regulations agrees with the jurisdiction of the constitutional court according to the nuclear legal protection obligations.

    Matveev, V. I.; Sidorov, D. B.

    2007-07-01

    A nonperturbatve theory of energy losses of fast heavy multiply charged structural ions in collisions with neutral complex atoms is elaborated with allowance for simultaneous excitations of ionic and atomic electron shells. Formulas for the effective deceleration that are similar to the well-known Bethe-Bloch formulas are derived. By way of example, the energy lost by partially stripped U q+ ions (10 ≤ q ≤ 70) colliding with argon atoms and also the energy lost by Au, Pb, and Bi ions colliding with various targets are calculated. The results of calculation are compared with experimental data.

  19. Electricity Crisis and Load Management in Bangladesh

    2012-09-01

    Full Text Available Bangladesh is a densely populated country. Only a small part of her area is electrified which cover around 18% of total population. The people who are in the electrified area are suffering from severe load shedding. A systematic load management procedure related to demand side may improve the situation is the research problem. The major objectives serve by the research are to analyze contemporary electricity status with a view to drawing inference about demand supply gap and extracting benefits from load management. Data supplied by the Bangladesh Power Development Board, World Bank and outcome of survey are analyzed with some simple statistical tools to test the hypothesis. Analysis discloses that with properly managed uses of electricity with load switch and rotation week-end can improve the concurrent condition of electricity. Moreover, introducing smart distribution system, reducing system loss, shifting load to off-peak, large scale use of prepaid mete, observing energy week and using energy efficient home and office appliance are recommended to improve load through demand side management. Some other recommendations such as introducing alternative energy, public private partnership and using renewable energy development and producing energy locally are made for load management from the supply side.

  20. The Russian Federation's Ministry of Atomic Energy: Programs and Developments

    International Nuclear Information System (INIS)

    This paper reviews select programs driving the Ministry of Atomic Energy of the Russian Federation's (Minatom) efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the US over the next three to five years. The paper's findings are: (1) Despite numerous cabinet displacements throughout the Yeltsin administration, Yevgeny Adamov was reappointed Minister on four occasions. With Boris Yeltsin's January 1, 2000 resignation, Adamov's long-term position as the head of the Ministry is more tenuous, but he will likely retain his position until at least the March 2000 elections. Acting President Vladimir Putin is unlikely to reorganize his cabinet prior to that date and there are no signs that Putin is dissatisfied with Adamov's leadership of Minatom. (2) Adamov's chief priorities are downsizing Minatom's defense sector, increasing the oversight of subsidiary bodies by the central bureaucracy and consolidating commercial elements of the Ministry within an umbrella organization called Atomprom. (3) Viktor Mikhaylov, Adamov's predecessor and critic of his reform efforts, has been relieved of his duties as First Deputy Minister. While he retains his positions as Chief of the Science Councils and Chief Scientist at Arzamas-16, his influence on Minatom's direction is greatly diminished. Adamov will likely continue his efforts to further marginalize Mikhaylov in the coming year. (4) Securing extra-budgetary sources of income continues to be the major factor guiding Minatom's international business dealings. The Ministry will continue to aggressively promote the sale of nuclear technology abroad, often to countries with questionable nonproliferation commitments. (5) Given the financial difficulties in Russia and Minatom's client states, however, few nuclear development programs will come to fruition for a number of years, if ever. Nevertheless, certain peaceful nuclear cooperation agreements should be carefully

    Tissue Banking and Biomaterial Research Unit (TBBRU), the only tissue bank of Bangladesh, has been established to create an available supply of human tissue allografts for transplantation in Bangladesh. Since its establishment in 2003, TBBRU strictly follows the guidelines of tissue banking setup by the International Atomic Energy Agency, the European Association of Tissue Banks and the American Association of Tissue Banks. Though started serving from earlier, regular supply of tissue allografts from this bank were documented at the end of 2006. From January 2007 to December 2014, 3747 bones and 5772 amniotic sacs were collected from live tissue donors. During this period, 59,489 cc bone allografts and 23,472 pieces of amniotic membrane allografts were processed. In the same period, 58,483 cc bone allografts and 20,786 pieces membrane were supplied to different hospitals throughout the country on the basis of demand. The outcomes of the concerted efforts of tissue banking professionals and physicians were the restoration of health and hope of 3662 patients during the last 8 years.

    Using the "Pseudo-invariant eigen-operator" method we find the energy-gap of the Jaynes-Cummings Hamiltonian model of an atom-cavity system. This model takes the atomic centre-of-mass motion into account. The supersymmetric structure is involved in the Hamiltonian of an atom-cavity system. By selecting suitable supersymmetric generators and using supersymmetric transformation the Hamiltonian is diagonalized and energy eigenvectors are obtained.

    A new approach for computing the atom-in-molecule [quantum theory of atoms in molecule (QTAIM)] energies in Kohn-Sham density-functional theory is presented and tested by computing QTAIM energies for a set of representative molecules. In the new approach, the contribution for the correlation-kinetic energy (T(c)) is computed using the density-functional theory virial relation. Based on our calculations, it is shown that the conventional approach where atomic energies are computed using only the noninteracting part of the kinetic energy might be in error by hundreds of kJ/mol.

  12. Self-energy and interaction energy of stacking fault in fcc metals calculated by embedded-atom method

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The stacking fault energies of five fcc metals (Cu, Ag, Au, Ni and Al) with various quantivalences have been calculated by embedded-atom method (EAM). It indicated that the stacking fault energy is mainly determined by the metallic bond-energy and the lattice constant. Thus, monovalent fcc metals should have different stacking fault energies, contrary to Attree's conclusion. The interaction energy between stacking faults one {111} layer apart in a fcc metal is found to be 1/40-1/250 of its self-energy, while it becomes zero when the two stacking faults are two layers apart. The twin energy is just half of the energy of intrinsic stacking fault energy without the consideration of lattice relax-ation and the energy of a single intrinsic stacking fault is almost the same as that of extrinsic stacking fault, which are consistent with the results from the calculation of Lennard-Jones force between atoms, but differ from Attree's result.

  13. Issues in developing a mitigation strategy for Bangladesh

    Energy Technology Data Exchange (ETDEWEB)

    Asaduzzaman, M. [Bangladesh Institute of Development Studies, Dhaka (Bangladesh)

    1996-12-31

    Bangladesh, it is by now well-known, is at the receiving end, in the literal sense of the term, of the global climate change and its potential impacts. She contributes very little to the current global emission of greenhouse gases (GHGs). The Emission Inventory under the present umbrella project, Bangladesh Climate Change Study (BCCS), has found that her annual emission of carbon has been only 3.99 mn metric tons per year. An earlier study arrived at exactly the same figure. The figures for estimated release of methane is far less firm. The estimated methane emission in 1990 could be anywhere between 1 million and 6 million metric tons. In any case the total emission is unlikely to be more than one-half of one percent of the global total. On the other hand, however, she faces specter of widespread and more frequent floods, more frequent droughts, cyclones and above all sea-level rise (SLR) which may inundate a substantial part of the country all of these bringing in immeasurable misery and destitution and loss of income, employment and growth. One would expect that in such a situation, Bangladesh`s basic concern should be to prepare an appropriate adaptation strategy. This is already a major policy concern of the Government. There is, however, an increasing realization that Bangladesh should as well emphasize an appropriate mitigation strategy (MS). There may be at least three reasons why this should be so. The first is that she is a signatory of the Framework Convention on Climate Change. The second is that in the medium, if not short term she expects major growth due to a developing economy. Third is that Bangladesh depends primarily on fossil fuel imports for energy, and will become a larger source with further development.

    The durability evaluation of protected polymers intended for use in low Earth orbit (LEO) has necessitated the use of large-area, high-fluence, atomic oxygen exposure systems. Two thermal energy atomic oxygen exposure systems which are frequently used for such evaluations are radio frequency (RF) plasma ashers and electron cyclotron resonance plasma sources. Plasma source testing practices such as ample preparation, effective fluence prediction, atomic oxygen flux determination, erosion measurement, operational considerations, and erosion yield measurements are presented. Issues which influence the prediction of in-space durability based on ground laboratory thermal energy plasma system testing are also addressed.

  15. Theory of ion-atom collisions at high energy, I

    International Nuclear Information System (INIS)

    Electron capture process by an ion from a neutral atom is one of the fundamental problems in the theory of atomic collision physics. Here a brief review is given mainly on the processes of non-radiative and radiative electron capture (charge transfer and REC). The main mechanism which govern the charge transfer process is introduced and the characteristic feature which is predicted by the theory is explained. As for the radiative electron capture process, after introducting the present theories, the full-quantum mechanical theoretical treatment is introduced. The theory leads a result which includes some inconsistency with formulae obtained by guage transformation. The relativistic quantum mechanical treatment is being tried in order to remove this inconsistency. The some results including mass and velocity dependence are reported and discussed. (author)

    Reflection electron energy loss spectra from some insulating materials (CaCO{sub 3}, Li{sub 2}CO{sub 3}, and SiO{sub 2}) taken at relatively high incoming electron energies (5–40 keV) are analyzed. Here, one is bulk sensitive and a well-defined onset of inelastic excitations is observed from which one can infer the value of the band gap. An estimate of the band gap was obtained by fitting the spectra with a procedure that includes the recoil shift and recoil broadening affecting these measurements. The width of the elastic peak is directly connected to the mean kinetic energy of the atom in the material (Doppler broadening). The experimentally obtained mean kinetic energies of the O, C, Li, Ca, and Si atoms are compared with the calculated ones, and good agreement is found, especially if the effect of multiple scattering is taken into account. It is demonstrated experimentally that the onset of the inelastic excitation is also affected by Doppler broadening. Aided by this understanding, we can obtain a good fit of the elastic peak and the onset of inelastic excitations. For SiO{sub 2}, good agreement is obtained with the well-established value of the band gap (8.9 eV) only if it is assumed that the intensity near the edge scales as (E − E{sub gap}){sup 1.5}. For CaCO{sub 3}, the band gap obtained here (7 eV) is about 1 eV larger than the previous experimental value, whereas the value for Li{sub 2}CO{sub 3} (7.5 eV) is the first experimental estimate.

  17. Atom probe tomography simulations and density functional theory calculations of bonding energies in Cu3Au

    KAUST Repository

    Boll, Torben

    2012-10-01

    In this article the Cu-Au binding energy in Cu3Au is determined by comparing experimental atom probe tomography (APT) results to simulations. The resulting bonding energy is supported by density functional theory calculations. The APT simulations are based on the Müller-Schottky equation, which is modified to include different atomic neighborhoods and their characteristic bonds. The local environment is considered up to the fifth next nearest neighbors. To compare the experimental with simulated APT data, the AtomVicinity algorithm, which provides statistical information about the positions of the neighboring atoms, is applied. The quality of this information is influenced by the field evaporation behavior of the different species, which is connected to the bonding energies. © Microscopy Society of America 2012.

    A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move through the pump as independent particles. Under certain conditions, these pumps can create net transport of atoms from one reservoir to the other. While such systems are sometimes called "quantum pumps," they are also models of classical chaotic transport, and their quantum behavior cannot be understood without study of the corresponding classical behavior. Here we examine classically such a pump's effect on energy and temperature in the reservoirs, in addition to net particle transport. We show that the changes in particle number, of energy in each reservoir, and of temperature in each reservoir vary in unexpected ways as the incident particle energy is varied.

    We observe strong energy-dependent quantum defects in the scaled-energy Stark spectra for |M|=1 Rydberg states of barium atoms at three scaled energies: ε= -2.000, ε= -2.500 and ε=-3.000. In an attempt to explain the observations, theoretical calculations of closed orbit theory based on a model potential including core effect are performed for non-hydrogenic atoms. While such a potential has been uniformly successful for alkali atoms with a single valence electron, it fails to match experimental results for barium atoms in the 6snp Rydberg states with two valence electrons. Our study points out that this discrepancy is due to the strong perturbation from the 5d8p state, which voids the simple approximation for constant quantum defects of principle quantum number n.

  1. Opinions of Cordoba's politicians and journalists on atomic energy

    International Nuclear Information System (INIS)

    The perception of the nuclear energy of journalist of the Cordoba city and of the member of the legislative body of the Province was investigated. In general a high degree of ignorance on nuclear energy and its uses was found. The majority of them considers nuclear energy a great danger for the society and describes it as a potential damage for health and environment. Little is known about medical applications, food irradiation, etc. As a consequence nuclear energy has no priority in journalist and lawmakers agendas. (author)

  2. Anti-terror/non-proliferation efforts and South Korea's planning for atomic energy

    International Nuclear Information System (INIS)

    This study deals with the relationship between rapidly changing international security environments, the US security policy on the one hand, and policy environments of atomic energy. Based on the notion that the issue of atomic energy development is closely interrelated with the situation of international security especially after the tragic incident of 9/11, this study focuses on the impact of changing security environments on the conditions under which South Korea uses atomic power. It also deals with the subject of how the new framework of NPT, and the policy of IAEA influences upon South Korea's atomic polices in the future. This study examines the nature and contents of the US foreign policy and its efforts toward nonproliferation and counterproliferation. This study also deals with the Iranian case in which the US efforts of counterproliferation and Iranian argument for the rights of peaceful use of atomic energy based on the concept of national sovereignty. The Iranian case sheds light on the most acute aspect of current stage of nonproliferation, but also on the way of solving the North Korean nuclear crisis. This study also take issue with the future course of nonprolieration and the South Korea's policy for its maximum use of atomic energy

  3. Effective atomic numbers for photon energy absorption of some low-Z substances of dosimetric interest

    International Nuclear Information System (INIS)

    Effective atomic numbers for photon energy absorption (ZPEAeff) and effective atomic numbers for photon interaction (ZPIeff) of some low-Z substances of dosimetric interest such as A-150 tissue-equivalent plastic (A150TEP), alanine, bakelite, Gafchromic sensor (GS), plastic scintillator (PS), polyethylene, mylar, polystyrene, perspex, radiochromic dye film nylon base (RDF : NB), tissue-equivalent gas-methane based (TEG : MB) and tissue-equivalent gas-propane based (TEG : PB) have been calculated by a direct method in the energy region of 1 keV-20 MeV. Experimental mass attenuation coefficients and ZPIeff of some of these substances at selected photon energies of 26.34, 33.2, and 59.54 keV have been obtained and compared with theoretical values. The ZPEAeff and ZPIeff values steadily increases up to 6-15 keV, and then they steadily decrease up to 600-1500 keV for all the substances studied. From 1.5 MeV, the values increases with increase in energy up to 20 MeV. Significant differences up to 33.68% exist between ZPIeff and the ZPEAeff in the energy region of 10-150 keV. The single effective atomic numbers obtained using the program XMuDat (ZXMUDATeff ) are found to be significantly higher compared to those of ZPEAeff and ZPIeff values in the entire energy of interest for all the substances studied. The directly calculated ZPEAeff and ZPIeff values vary with energy compared to the energy-independent effective atomic numbers predicted by various theoretical expressions. The effects of absorption edges on effective atomic numbers and their variation with photon energy and the possibility of defining two set values of effective atomic numbers below the absorption edges of elements present in the composite substances are discussed

    1993-01-01

    We re-examine the justification for the imposition of regular boundary conditions on the wavefunction at the Coulomb singularity in the treatment of the hydrogen atom in non-relativistic quantum mechanics. We show that the issue of the correct boundary conditions is not independent of the physical structure of the proton. Under the physically reasonable assumption that the finite size and structure of the proton can be represented as a positive correction to the Coulomb potential, we give a justification for the regular boundary condition, which, in contrast to the usual treatments, is physically motivated and mathematically rigorous. We also describe how irregular boundary conditions can be used to model non-positive corrections to the Coulomb potential.

  10. Direct measurement of desorption and diffusion energies of O and N atoms physisorbed on amorphous surfaces

    CERN Document Server

    Minissale, Marco; Dulieu, François

    2016-01-01

    Physisorbed atoms on the surface of interstellar dust grains play a central role in solid state astrochemistry. Their surface reactivity is one source of the observed molecular complexity in space. In experimental astrophysics, the high reactivity of atoms also constitutes an obstacle to measuring two of the fundamental properties in surface physics, namely desorption and diffusion energies, and so far direct measurements are non-existent for O and N atoms. We investigated the diffusion and desorption processes of O and N atoms on cold surfaces in order to give boundary conditions to astrochemical models. Here we propose a new technique for directly measuring the N- and O-atom mass signals. Including the experimental results in a simple model allows us to almost directly derive the desorption and diffusion barriers of N atoms on amorphous solid water ice (ASW) and O atoms on ASW and oxidized graphite. We find a strong constraint on the values of desorption and thermal diffusion energy barriers. The measured b...

    International Nuclear Information System (INIS)

    The information processing using computers has been carried out in the field of atomic energy science internationally since early period, and CINDA and NEUDADA, which are the accumulation of the nuclear data on neutrons, and INIS for the search of literatures are the examples. In Japan, the Japan Atomic Energy Research Institute has functioned as the center for collecting, evaluating and distributing the international informations on atomic energy. In universities, various researcher groups have endeavored to make and utilize the data bases with the advance of functions of large computer centers. In the future plan of the Kyoto University Reactor Research Institute, the establishment of Atomic Energy Science Information Center is planned. In order to discuss the concept for this and refer to the state of activities in other fields, the short period study meeting was helt in 1979, and the special study meeting on the on-line processing of searching the scientific informations and literatures on atomic energy was established in 1980. This report summarizes the results of studies and investigations published in this special study meeting. The abstracts of five papers on various data bases are given. (Kako, I.)

  14. Energy considerations in spraying process of a spill-return pressure-swirl atomizer

    International Nuclear Information System (INIS)

    Graphical abstract: - Highlights: • We analyse energy conversion in simplex and spill-return pressure-swirl atomizer. • Inlet (pressure) energy converts into liquid motion with nozzle efficiency ∼58%. • Kinetic energy of developed spray at closed spill line is ∼33% of the inlet energy. • It consists of energy of droplets (∼2/3) and entrained air (1/3). • Atomization efficiency is <0.3%; it declines with inlet pressure and spill opening. - Abstract: The work focuses on energy conversion during the internal flow, discharge and formation of the spray from a pressure-swirl (PS) atomizer in the simplex as well as spill-return mode. Individual energy forms are described in general and assessed experimentally for a particular PS atomizer and light heating oil as a medium. The PS spray was observed at various loads to investigate the liquid breakup process and the spray characteristics. Spatially resolved diameters and droplet velocities, measured by means of phase-Doppler anemometry, served for estimation of the energy characteristics in the PS spray. The input energy given by the potential energy of the supplied liquid partially converts into the kinetic energy (KE) in the swirling ports with hydraulic loss in per cent scale. Most of the pressure drop is associated with rotational motion in the swirl chamber with total conversion efficiency at the exit orifice ∼58%. The rest of the input energy ends up as friction loss, leaving room for improvement. The overall value (ID32) of the Sauter mean diameter of droplets in the spray, D32, varies with pressure drop Δpl powered to −0.1. The radial profiles of D32 widen with the increase in spill/feed ratio (SFR), but the ID32 remain almost constant within the studied SFR range. The spray KE at closed spill line covers the droplet KE (21–26%) and that of entrained air (10–13%), both moderately varying with Δpl. The specific KEs of both the liquid and air markedly drop down with the spill line opening

    We report the features of an ion source based on two-color photoionization of a laser-cooled cesium beam outsourced from a pyramidal magneto-optical trap. The ion source operates in continuous or pulsed mode. At acceleration voltages below 300 V, it delivers some ten ions per bunch with a relative energy spread Δ Urms/U ≃0.032 , as measured through the retarding field-energy-analyzer approach. Space-charge effects are negligible thanks to the low ion density attained in the interaction volume. The performances of the ion beam in a configuration using focused laser beams are extrapolated on the basis of the experimental results. Calculations demonstrate that our low-energy and low-current ion beam can be attractive for the development of emerging technologies requiring the delivery of a small amount of charge, down to the single-ion level and its eventual focusing in the 10-nm range.

    Johnson, Ray O.

    1993-08-01

    Pulsed and steady-state photolysis experiments have been conducted to determine the rate coefficients for collisional deactivation of the spin-orbit excited state of atomic bromine, Br((sup 2)P(sub 1/2)). Pulsed lifetime studies for quenching by Br2 and CO2 established absolute rate coefficients at room temperature of k(sub Br2) = 1.2 +/- 0.1 x 10(exp-12) and k(sub CO2) = 1.5 +/0.2 x 10(exp-11) cu cm/molecule-s. Steady-state photolysis methods were used to determine the quenching rates for the rare gases, N2, 02, H2, D2, NO, NO2, N2O, SF6, CF4, CH4, CO, CO2, COS, SO2, H2S, HBr, HC1, and HI relative to that for Br2. Quenching rate temperature dependence was examined for Br2, CO2, N2O, HCl, COS, NO, and NO2 for temperatures from 300 to 420 K. Diffusion and three body effects were examined in order to determine the slowest relative quenching rate measurable by this experimental technique.

  5. Women in physics in Bangladesh

    Science.gov (United States)

    Choudhury, Shamima K.

    2013-03-01

    Bangladesh has had a glorious physics tradition since the beginning of the last century, when the physicist S.N. Bose published a groundbreaking paper with Albert Einstein on Bose-Einstein statistics. However, women in Bangladesh traditionally have not been able to make their way in the realm of science in general and physics in particular. Since Bangladesh achieved independence in 1971, the situation has gradually changed and more and more women choose physics as an academic discipline. The percentage of women students in physics rose from 10% in 1970 to almost 30% in 2010. In recent years, women physicists have actively participated in many activities promoting science and technology, creating awareness among the public about the importance of physics education. The present status of women physicists in academic, research, and administrative programs in the government and private sectors in Bangladesh is reported. The greater inclusion of women scientists, particularly physicists, in policy-making roles on important issues of global and national interest is suggested.

  6. Modern population trends in Bangladesh.

    Science.gov (United States)

    Abul-basher, M M

    1985-01-01

    Population growth trends in Bangladesh in the 1871-1981 period were analyzed, with emphasis on fertility and mortality differentials, to provide a basis for population planning. Following proclamation of British Imperial Rule in 1857, mortality rates in Bangladesh began to decline as a result of preventive measures against natural disasters such as draught and famine, but the fertility rate remained unaltered. The demographic pattern was unstable over time, reflecting the impact of the influenza epidemic of 1918-19, war, migration, and economic development. Population growth accelerated greatly during the 1961-74 period, when industrialization emerged and job opportunities were created in the urban centers. Economic hardship, food shortages, and the introduction of family planning curbed urban growth drastically and total growth to some extent in 1974-81. On the average, growth has been higher in the Dhaka and Chittagong Divisions of Bangladesh than in the Khulna and Rajshahi Divisions. Differences in population growth among the regions are attributable largely to internal and external migration. The regression polynomial model best fits past population trends in Bangladesh and can reproduce the observed population by 99.60%. This polynomial is most suitable for graduation and prediction of population trends. PMID:12280834

    This paper describes the achievements of a program in which technology education is provided to cultivate practical core engineers for low-level radiation. It was made possible by means of (1) an introductory education program starting at an early age and a continuous agenda throughout college days and (2) regional collaboration. First, with regard to the early-age introductory education program and the continuous education agenda, the subjects of study related to atomic energy or nuclear engineering were reorganized as “Subjects related to Atomic Power Education” for all grades in all departments. These subjects were included in the syllabus and the student guide book, emphasizing a continuous and consistent policy throughout seven-year college study, including the five-year system and additional two-year advanced course. Second, to promote practical education, the contents of lectures, experiments, and internships were enriched and realigned in collaboration with the Japan Atomic Energy Agency, Okayama University and The Cyugoku Electric Power Co., Inc. In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects were undertaken to enhance the educational and research activities. In consequence, it has been estimated that there is now a total of fourteen subject areas in atomic energy technology, more than eight-hundred registered students in the department, and thirteen members of the teaching staff related to atomic energy technology. Furthermore, the “Tsuyama model” is still being developed. This program was funded by the Ministry of Education, Culture, Sports, Science and Technology. (author)

  11. Inquiries about awareness and knowledge of children and pupils on the concept related with atomic energy

    International Nuclear Information System (INIS)

    There is almost no chance to learn about the words (atomic energy), (radioactivity) and (radiation) in the middle and/or high school educations in Japan, because physics is one of the options in the high school curriculum, and 80-90% of students do not like to choose physics. This inquires aim to know the level of their knowledge on energy resources, atomic energy, radioactivity, radiation, and information sources on their related knowledge. Inquiries are made for the middle and high school students in Tokushima and Tsuruga. There are coal power plants in Tokushima, while atomic power plants in Tsuruga. Fossils energy gets the highest points in Tokushima, while Atomic energy gets the highest points in Tsuruga for a present-day energy source. Solar energy sources get the highest point as a promising 21st century energy source in both prefectures, especially for female students. Radioactivity reminds them of words atomic bomb, disease, injury, and harmful, those give very negative images. Radiation reminds them of words roentgen, radiation therapy, x-ray, and hospital use, those designate a sort of plus-image. More than 50 to 60% of them obtained their knowledge from mass media, particularly, television. In addition, less than a few % of them can give any scientific description about these words. As a whole, authors can say that the students have got a certain concept for these words from information of mass media. Meanwhile the school education has approximately no effect on the formation of their concept. Authors are giving some advises and recommendations for the school education and mass media in Japan. (Y.

    2004-01-01

    The surface energies for 38 surfaces of fcc metals Cu, Ag, Au, Ni, Pd, Pt, Al, Pb, Rh and Ir have been calculated by using the modified embedded-atom method. The results show that, for Cu, Ag, Ni, Al, Pb and Ir, the average values of the surface energies are very close to the polycrystalline experimental data. For all fcc metals, as predicted, the close-packed (111) surface has the lowest surface energy. The surface energies for the other surfaces increase linearly with increasing angle between the surfaces (hkl) and (111). This can be used to estimate the relative values of the surface energy.

  18. Computational model for noncontact atomic force microscopy: energy dissipation of cantilever

    Science.gov (United States)

    Senda, Yasuhiro; Blomqvist, Janne; Nieminen, Risto M.

    2016-09-01

    We propose a computational model for noncontact atomic force microscopy (AFM) in which the atomic force between the cantilever tip and the surface is calculated using a molecular dynamics method, and the macroscopic motion of the cantilever is modeled by an oscillating spring. The movement of atoms in the tip and surface is connected with the oscillating spring using a recently developed coupling method. In this computational model, the oscillation energy is dissipated, as observed in AFM experiments. We attribute this dissipation to the hysteresis and nonconservative properties of the interatomic force that acts between the atoms in the tip and sample surface. The dissipation rate strongly depends on the parameters used in the computational model.

  20. High energy-intensity atomic oxygen beam source for low earth orbit materials degradation studies

    International Nuclear Information System (INIS)

    A high intensity (1019O-atoms/s-sr) high energy (5 eV) source of oxygen atoms has been developed that produces a total fluence of 1022 O-atoms/cm2 in less than 100 hours of continuous operation at a distance of 15 cm from the source. The source employs a CW CO2 laser sustained discharge to form a high temperature (15,000 K) plasma in the throat of a 0.3-mm diameter nozzle using 3--8 atmospheres of rare gas/O2 mixtures. Visible and infrared photon flux levels of 1 watt/cm2 have been measured 15 cm downstream of the source while vacuum UV (VUV) fluxes are comparable to that measured in low earth orbit. The reactions of atomic oxygen with kapton, Teflon, silver, and various coatings have been studied. The oxidation of kapton (reaction efficiency = 3 /times/ 10/sup /minus/24/ cm /+-/ 50%) has an activation energy of 0.8 Kcal/mole over the temperature range of 25/degree/C to 100/degree/C at a beam energy of 1.5 eV and produces low molecular weight gas phase reaction products (H2O, NO, CO2). Teflon reacts with ∼0.1--0.2 efficiency to that of kapton at 25/degree/C and both surfaces show a rug-like texture after exposure to the O-atom beam. Angular scattering distribution measurements of O-atoms show a near cosine distribution from reactive surfaces indicating complete accommodation of the translational energy with the surface while a nonreactive surface (nickel oxide) shows specular-like scattering with 50% accommodation of the translational energy with the surface. A technique for simple on orbit chemical experiments using resistance measurements of coated silver strips is described. 9 figs

  1. Atomic energy in the United States in 1992

    International Nuclear Information System (INIS)

    The use of energy may be constrained by a growing national consensus that we must choose; future courses that minimize adverse effect on public health, public safety, and the environment. It is believed nuclear power will be able to meet this challenge - more adequately than most fossil fuels. Thus it follows that the growth of nuclear power will be fostered by this trend. The United States today has contractual commitments of about 150 power plants with total capacity of about 130 million kilowatts electrical. When all of these plants are on line, by about 1980, that capacity will be equal to about 35% of our present electrical generating capacity. Of these commitments, 95% are for light water reactors - 62% for pressurized water and 33% for boiling water. The remaining 5% are high- temperature gas-cooled reactors. In this period of rapid expansion we are placing heavy emphasis on programmes to achieve higher levels of standardization, with the objective of improvements in safety, reliability and economics. Standardization will also shorten licensing reviews, provide for efficiency of labour and reduce maintenance problems. Meanwhile, improved technology in heat rejection techniques such as dry cooling will help to minimize the environmental problems, in addition, methods may be introduced to use rejected heat for beneficial purposes, such as food production in agriculture and aquaculture, as well as urban and industrial applications. Also during this period, biological research can be expected to result in continued progress toward identifying and understanding the effects of energy generation on man and his environment. With this increased knowledge, we will be better able to make wise decisions regarding the most effective use of all energy sources. The next major development step is the breeder reactor, which will achieve maximum utilization of fission fuels

  4. The International Atomic Energy Agency: activities and relationship with Mexico

    International Nuclear Information System (INIS)

    Legal and political studies on the activities of the IAEA infer that the pacific uses of nuclear energy become more significant every day in the ambit of international relationships. The studies analyze as a whole relationships among member states. The first part is divided into four chapters, starting with the background and creation of the agency, its structure, statutes, amendments and the performance of its main organisms. It continues to describe mechanisms and programmes carried out, including cooperation agreements between the IAEA and other specialized organizations in the United Nations. It ends up with the IAEA performance resulting from different treaties. The second part examines Mexican norms on nuclear matter as well as relationships between Mexico and the IAEA. It demonstrates that achievements in the Agency have been possible because of the establishment of an international cooperation basis, which avoids duplicity of actions. The conclusions recommend joint efforts from both the developed and the developing countries in the following: a) to imbue public opinion with the goodness of nuclear energy; b) to discourage the construction and operation of nuclear installations; c) to unify national standards on nuclear safety and control; d) to decrease export restrictions, based on safeguards; e) to promote internal nuclear research in Mexico or throught regional integration agreements, with technical assistance and support from the IAEA.

    Bangladesh is a country with a high burden of micronutrient malnutrition. Stunting affects 41 % of children aged under 5 years. Zn is one of the key micronutrients that is associated with stunting. The present study, as part of the national micronutrient survey 2011-2012, revealed for the first time the nationally representative prevalence of Zn deficiency and determined the associations of the condition. A cross-sectional 'nationwide' survey was conducted in pre-school-age children (6-59 months; PSAC) and non-pregnant non-lactating women (15-49 years; NPNLW). Multistage random sampling was done in 150 clusters; fifty in each of the rural, urban and slum strata. Data were analysed on 662 PSAC and 1073 NPNLW. Serum Zn was assayed by atomic absorption spectrophotometry. Zn deficiency was defined as serum Zn of origin Zn (β = -0·13; P = 0·038) determined higher and lower status of Zn in PSAC, respectively. Zn deficiency was highly prevalent in Bangladesh, and it was principally related to inadequate quality of diet. To improve Zn nutrition, Bangladesh needs to strengthen research and programmes related to Zn biofortification, fortification and phytate-reducing technologies in the food system in the short and medium term. In addition, promotion of animal-source Zn for all is important in the long run. PMID:27547388

  6. Intermediate-energy electron scattering by atomic hydrogen

    International Nuclear Information System (INIS)

    Both elastic and inelastic scattering were studied in the framework of the close-coupling equations. The models were formulated in terms of integral equations for T-matrices in momentum space. Using this representation it was possible to study the effects of approximations to the multiple-scattering series in a direct manner. For elastic scattering it was established that the approximations made in using a second-order optical-potential formalism gave rise to at most 10% error in the reaction mechanism at 50 eV and considerably less at higher energies. Inelastic 1s-2s and 1s-2p scattering was analysed in terms of a three-state close-coupling model and approximations to it. The marked sensitivity of the angular correlation parameters to approximation was shown. It was suggested that detailed agreement between theory and experiment requires a close-coupling model containing several more channels

  7. Evolution of the Atomic Energy Corporation of South Africa

    International Nuclear Information System (INIS)

    In order to understand the AEC in its present form and its strategic positioning for the next century, it is essential that cognisance be taken of its evolution over the past 40 years and, in particular, also the external forces which triggered major strategic re-orientation actions in the past. These resulted in a fundamentally downsized organization (by about 80%) which will in the new millennium be judged on its ability to make nuclear technology available for the needs of a developing country, discharge the nuclear liabilities of the past and commercially exploit its technology base to contribute to national economic growth. The Corporation has a strong programme in isotope applications and nuclear waste management. For the future it is looking forward to develop a Pebble Bed Modular Reactor for safe nuclear energy production. (author)

  8. Hydrogen atom wave function and eigen energy in the Rindler space

    CERN Document Server

    Dai, De-Chang

    2016-01-01

    We study the hydrogen atom eigenstate energy and wave function in the Rindler space. The probability distribution is tilted because the electric field of the nucleus is no longer spherically symmetric. The hydrogen atom therefore cannot be treated exactly in the same way as what it is in an inertial frame. We also find that if the external force accelerates only the nucleus and then the nucleus accelerates its surrounding electrons through electromagnetic force, the electrons can tunnel through the local energy gap and split the hydrogen atom into an ion. This is similar to what one expects from the Stark effect. However, the critical acceleration is about $3\\times 10^{22} m/s^2$. It is well beyond the gravitational acceleration on a regular star surface.

    Arsenic is a highly toxic element and its presence in food composites is a matter of concern to the well being of both humans and animals. Arsenic-contaminated groundwater is often used in Bangladesh and West Bengal (India) to irrigate crops used for food and animal consumption, which could potentially lead to arsenic entering the human food chain. In this study, we used graphite furnace atomic absorption spectroscopy to determine the total arsenic concentrations in a range of foodstuffs, including vegetables, rice and fish, imported into the United Kingdom from Bangladesh. The mean and range of the total arsenic concentration in all the vegetables imported from Bangladesh were 54.5 and 5-540 {mu}g/kg, respectively. The highest arsenic values found were for the skin of Arum tuber, 540 {mu}g/kg, followed by Arum Stem, 168 {mu}g/kg, and Amaranthus, 160 {mu}g/kg. Among the other samples, freshwater fish contained total arsenic levels between 97 and 1318 {mu}g/kg. The arsenic content of the vegetables from the UK was approximately 2- to 3-fold lower than those observed for the vegetables imported from Bangladesh. The levels of arsenic found in vegetables imported from Bangladesh in this study, in some cases, are similar to those previously recorded for vegetables grown in arsenic-affected areas of West Bengal, India, although lower than the levels reported in studies from Bangladesh. While the total arsenic content detected in our study in vegetables, imported from Bangladesh, is far less than the recommended maximum permitted level of arsenic, it does provide an additional source of arsenic in the diet. This raises the possibility that the level of arsenic intake by certain sectors of the UK population may be significantly higher then the general population and requires further investigations.

    This study applies different definitions of what previous authors have called the monsoon over Bangladesh. The aim is to identify the definitions that most resemble the perceptions of the local rural communities and how they define the monsoon. Considering how the local communities define the monsoon is extremely important since these populations are most vulnerable to future changes in climate and more specifically monsoon rainfall. It has been pointed out previously that the monsoon research community had not reached a consensus on a unified definition of the monsoon rainy season. This problem seems to be profound in Bangladesh where results from the application of different definitions show very large discrepancies. Since these discrepancies exist, confusing terms such as monsoon, summer rainy season, and monsoon rainy season can have large implications for impact studies and interpretations of future climate projections. The results in this paper show that these terms need to be explicitly and carefully defined with regards to Bangladesh. Wind-, rain- and OLR-based definitions are applied to several different datasets to show how large these discrepancies can be over Bangladesh. Differences in onset dates are found to be around 8-9 pentads (40-45 days) in some regions of the country. The largest differences are seen in the north-east region, where rain-based definitions give much earlier onsets than wind- or OLR-based definitions. The results show that mesoscale phenomena could be influencing the climate in the north-east part of Bangladesh and causing much earlier summer rainfall. According to the results from a previous social study, the local communities in fact consider this early rainfall as the monsoon onset. By identifying the definition that best resembles the local community perceptions through out Bangladesh, then future information can be constructed, so that it is more easily understood by and applicable to the millions of people climate change will

    Within the scheme of the weakest bound electron potential model theory, the concept of spectral-level-like series is presented by reasonably classifying the Rydberg energy level of atom Al. Based on this concept, the regularities of the Rydberg energy levels are systematically studied. The deviations of the calculated values from the experimental values are generally about several percent of 1 cm, which is of high accuracy.

  9. Solar Home System (SHS) in rural Bangladesh: Ornamentation or fact of development?

    International Nuclear Information System (INIS)

    Energy requirement has been growing every day due to higher population growth, and consequently higher consumption. About one third of rural households of Bangladesh are connected to the grid. To meet the gap, solar energy has been treated as a feasible option for people in rural areas where grid connections are not available. A good number of organizations have been working together to provide Solar Home System (SHS) in rural Bangladesh. There is little evidence that supply of small scale energy supports significant rural development. This paper aims at understanding how increased energy access through SHS in rural Bangladesh contributes towards rural development. Recent published literatures on SHS in Bangladesh have been studied to get insight into the technical, financial, and operational as well as economic and social issues. Later the findings have been critically analyzed with respect to selected indicators of rural development. The study identified that increased access to energy through SHS in rural Bangladesh provides mostly recreational and leisure benefits with the so called ‘social status’; income generation is negligible while support for education is average. - Highlights: • No specific proof is there to conclude that SHS has contributed to development. • SHS's contribution to income generation and employment is not significant. • SHS is mostly used for entertainment and to uplift the so called ‘social status’

    2000-01-01

    The stacking fault energies of five fcc metals (Cu, Ag, Au, Ni and Al) with various quan-tivalences have been calculated by embedded-atom method (EAM). It indicated that the stacking fault energy is mainly determined by the metallic bond-energy and the lattice constant. Thus, monovalent fcc metals should have different stacking fault energies, contrary to Attree’s conclusion. The interaction energy between stacking faults one I 111 I layer apart in a fcc metal is found to be 1/40-1/250 of its self-energy, while it becomes zero when the two stacking faults are two layers apart. The twin energy is just half of the energy of intrinsic stacking fault energy without the consideration of lattice relaxation and the energy of a single intrinsic stacking fault is almost the same as that of extrinsic stacking fault, which are consistent with the results from the calculation of Lennard-Jones force between atoms, but differ from Attree’s result.

  15. Effect of external energy on atomic, crystalline and powder characteristics of antimony and bismuth powders

    2009-10-01

    Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are compared with the as received powders (control). The average particle sizes, 50 and 99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy had caused deformation and fracture as if the powders have been subjected to high energy milling. To be able to understand the reasons for these changes the powders are characterized by techniques such as X-ray diffraction (XRD), surface area determination (BET), thermal analytical techniques such as DTA–DTG, DSC–TGA and SDTA and scanning electron microscopy (SEM). The treated powder samples exhibited remarkable changes in the powder characteristics at all structural levels starting from polycrystalline particles, through single crystal to atoms. The external energy had changed the lattice parameters of the unit cell which in turn changed the crystallite size and density. The lattice parameters are then used to compute the weight and effective nuclear charge of the atom which showed significant variation. It is speculated that the external energy is acting on the nucleus through some reversible weak interaction of larger cross section causing changes in the proton to neutron ratios. Thus the effect is felt by all the atoms, and hence the unit cell, single crystal grain and grain boundaries. The stresses generated in turn may have caused deformation or fracture of the weak interfaces such as the crystallite and grain boundaries.

    We consider high energy electron scattering by hydrogen atoms in the presence of a laser field of moderate power and higher frequencies. If the field is a superposition of a linearly and a circularly polarized laser beam in a particular configuration, then we can show that circular dichroism in two photon transitions can be observed not only for the differential but also for the integrated cross sections, provided the laser-dressing of the atomic target is treated in second order perturbation theory and the coupling between hydrogenic bound and continuum states is involved.

  19. Strong field atomic ionization: Origin of high-energy structures in photoelectron spectra

    International Nuclear Information System (INIS)

    Two distinct interpretations have been proposed to account for conspicuous enhancements of the ionization peaks in the high energy part of above-threshold ionization spectra. One of them ascribes the enhancement to a multiphoton resonance involving an excited state, while other analysis performed for zero-range model potential link it to 'channel closings', i.e., to the change in the number of photons needed to ionize the atom when the laser intensity increases. We report the results of model calculations that confirm the existence of a resonant process in atoms and shed light on why short-range potential models can mimic the experimental observations

    2006-01-01

    The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission (AEC) was formally established, the Manhattan Project began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians (both domestic and abroad), such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture.

    We numerically investigate the dynamics of inward circular finite-energy Airy beams carrying different orbital angular momentum (OAM) numbers in a close-Λ three-level atomic vapor with the electromagnetically induced transparency (EIT) window. We report that due to the EIT induced by the microwave field, the transverse intensity distribution properties of Airy beam can be feasibly manipulated and modulated through adjusting OAM numbers l and the frequency detuning, as well as the propagation distance, in the multi-level atomic systems. What's more, the rotation of the beam also can be observed with different positions in atomic ensembles. The investigation may provide a useful tool for studying particle manipulation, signal processing and propagation in graded-index (GRIN) fibers.

    We examined the combined effect of atomic under- and hetero-coordination on the bond relaxation and electronic binding energy of Sc, Zr, and ScZr alloying using a combination of the bond-order-length-strength (BOLS) correlation and density functional theory (DFT) calculations. Observations strongly emphasize the relevance of core-level shifts as reliable X-ray photoelectron spectroscopy experimental descriptors of core-shell catalysis reactivity, along with under-coordinated atoms in bimetallic transition metal systems. The BOLS-DFT method provides enhanced catalysis reactivity and detects surface and alloy configurations, opening up the possibility to investigate more complex systems with irregularly under- and hetero-coordinated atoms.

  7. Optical meta-atom for localization of light with quantized energy

    CERN Document Server

    Lannebère, Sylvain

    2015-01-01

    The capacity to confine light into a small region of space is of paramount importance in many areas of modern science. Here, we suggest a mechanism to store a quantized "bit" of light - with a very precise amount of energy - in an open core-shell plasmonic structure ("meta-atom") with a nonlinear optical response. Notwithstanding the trapped light state is embedded in the radiation continuum, its lifetime is not limited by the radiation loss. Interestingly, it is shown that the interplay between the nonlinear response and volume plasmons enables breaking fundamental reciprocity restrictions, and coupling very efficiently an external light source to the meta-atom. The collision of an incident optical pulse with the meta-atom may be used to release the trapped radiation "bit".

    Electron capture processes for low energy Ar9+ ions colliding on Ar2 dimer targets are investigated, focusing attention on charge sharing as a function of molecule orientation and impact parameter. A preference in charge-asymmetric dissociation channels is observed, with a strong correlation between the projectile scattering angle and the molecular ion orientation. The measurements provide here clear evidences that projectiles distinguish each atom in the target and, that electron capture from near-site atom is favored. Monte Carlo calculations based on the classical over-the-barrier model, with dimer targets represented as two independent atoms, are compared to the data. They give a new insight into the dynamics of the collision by providing, for the di erent electron capture channels, the two-dimensional probability maps p(~b), where ~b is the impact parameter vector in the molecular frame.

    2016-09-01

    Multiconfiguration wave function expansions combined with configuration interaction methods are a method of choice for complex atoms where atomic state functions are expanded in a basis of configuration state functions. Combined with a variational method such as the multiconfiguration Hartree–Fock (MCHF) or multiconfiguration Dirac–Hartree–Fock (MCDHF), the associated set of radial functions can be optimized for the levels of interest. The present review updates the variational MCHF theory to include MCDHF, describes the multireference single and double process for generating expansions and the systematic procedure of a computational scheme for monitoring convergence. It focuses on the calculations of energies and wave functions from which other atomic properties can be predicted such as transition rates, hyperfine structures and isotope shifts, for example.

    Full Text Available In a year and a half after the events of March 2011, Japan excluded all their nuclear reactors, returning to fossil fuels as a basis in the energy field. The shock associated with nuclear disaster seemed to indicate an ultimate end of Japanese adventure with the atom. The situation has, however, significantly changed during the last several months, and the first nuclear reactor connected again to the electric network, is a proof of the change of the energy policy. The article aims to identify the current state of knowledge on the future of nuclear energy in the Japanese energy sector and adjustments proposed in the future energy mix. At the same time, it is an attempt to analyze the reasons that led the current Government of Prime Minister Abe to take very unpopular decisions to return to nuclear energy.

    2008-10-01

    An investigation of various heavy metals including the arsenic (As) poisoning in soils and vegetables in five upazillas under Feni district of Bangladesh was performed by neutron activation technique using the neutron irradiation facilities of TRIGA MARK II research reactor at Bangladesh Atomic Energy Research Establishment (BAERE), Savar, Dhaka. A total of 30 samples (15 surface soils and 15 foodstuffs) were studied in five Upazillas namely as, Sonagazi, Dagan Bhuiya, Feni Sadar, Fulgazi and Parsuram of Feni district taking three samples of each kind from each upazilla. Samples of each kind together with the standard reference material (SRM) were irradiated in the same neutron flux and the gamma-rays of nuclides from the irradiated samples were assessed and screened for As, Br, U, Th, Cr, Sc, Fe, Zn and Co in soils and As, Br, Na, K, Cr, Sc, Fe, Zn and Co in vegetables (i.e; eddoe, taro, green papaya, plantain, potato, callaloo, bottle ground and carambola). The measurement of gamma-rays was carried out by means of a calibrated high resolution HPGe detector. The concentration of product nuclides containing in the irradiated samples was determined from the peak count-rates of prominent gamma-lines for the corresponding nuclides. Among all contaminants, only As, Zn and Cr for both samples were focused because of their higher values compared with the local as well as the world typical values. The present results revealed that the mean levels of As in Parsuram, Feni Sadar and Pulgazi upazillas are higher than the world typical value of 2 mg/kg. The mean values of Zn and Cr for all upazillas are higher than the world typical values 32 and 27.9 mg/kg, respectively. For the case of vegetables, the mean concentration of As is found only in Eddoe (5.33 ppm) and Taro (1.46 ppm) collected from Sonagazi and Feni Sadar upazilla; which are higher than the values in Samta (0.1 ppm for eddoe and 0.44 ppm for taro) under Jessore district of Bangladesh. The mean concentrations of

    The pivotal role played by chemistry in all the stages of atomic energy programme, right from mineral exploration, materials processing, fuel fabrication, coolant, control and structural materials, reactor chemistry, fuel recycling and actinide partitioning to radioactive waste management, has been explicitly demonstrated in the last few decades. The discoveries and developments in chemical sciences that have contributed to the formulation and successful implementation of our nuclear programme are enormous. It is to the credit of all our colleagues of Department of Atomic Energy to reckon the chronology of mile stones in our programme and how they place our nation on the global map of nuclear energy. The theme meeting on Chemistry in Atomic Energy Programme is an outcome of the thinking of some of our colleagues in BARC to take stock of the accomplishments made hitherto and to prepare a roadmap to meet the challenges of future advanced reactor regimes, while safeguarding the strategic interests of mankind. It is not out-of-context to record here that India, with its rich experience, is poised to play a major role in the global nuclear power programme, through bilateral international collaborations as well as on the platform of IAEA.

  15. Visualizing the large-$Z$ scaling of the kinetic energy density of atoms

    CERN Document Server

    Cancio, Antonio C

    2016-01-01

    The scaling of neutral atoms to large $Z$, combining periodicity with a gradual trend to homogeneity, is a fundamental probe of density functional theory, one that has driven recent advances in understanding both the kinetic and exchange-correlation energies. Although research focus is normally upon the scaling of energies, insights can also be gained from energy densities. We visualize the scaling of the positive-definite kinetic energy density (KED) in closed-shell atoms, in comparison to invariant quantities based upon the gradient and Laplacian of the density. We notice a striking fit of the KED within the core of any atom to a gradient expansion using both the gradient and the Laplacian, appearing as an asymptotic limit around which the KED oscillates. The gradient expansion is qualitatively different from that derived from first principles for a slowly-varying electron gas and is correlated with a nonzero Pauli contribution to the KED near the nucleus. We propose and explore orbital-free meta-GGA models...

    In the exotic atoms where one atomic $1s$ electron is replaced by a $K^{-}$, the strong interaction between the $K^{-}$ and the nucleus introduces an energy shift and broadening of the low-lying kaonic atomic levels which are determined by only the electromagnetic interaction. By performing X-ray spectroscopy for Z=1,2 kaonic atoms, the SIDDHARTA experiment determined with high precision the shift and width for the $1s$ state of $K^{-}p$ and the $2p$ state of kaonic helium-3 and kaonic helium-4. These results provided unique information of the kaon-nucleus interaction in the low energy limit.

    This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

    The atomic solid state energy (SSE) scale originates from a plot of the electron affinity (EA) and ionization potential (IP) versus band gap (EG). SSE is estimated for a given atom by assessing an average EA (for a cation) or an average IP (for an anion) for binary inorganic compounds having that specific atom as a constituent. Physically, SSE is an experimentally-derived average frontier orbital energy referenced to the vacuum level. In its original formulation, 69 binary closed-shell inorganic semiconductors and insulators were employed as a database, providing SSE estimates for 40 elements. In this contribution, EA and IP versus EG are plotted for an additional 92 compounds, thus yielding SSE estimates for a total of 64 elements from the s-, p-, d-, and f-blocks of the periodic table. Additionally, SSE is refined to account for its dependence on oxidation state. Although most cations within the SSE database are found to occur in a single oxidation state, data are available for nine d-block transition metals and one p-block main group metal in more than one oxidation state. SSE is deeper in energy for a higher cation oxidation state. Two p-block main group non-metals within the SSE database are found to exist in both positive and negative oxidation states so that they can function as a cation or anion. SSEs for most cations are positioned above -4.5 eV with respect to the vacuum level, and SSEs for all anions are positioned below. Hence, the energy -4.5 eV, equal to the hydrogen donor/acceptor ionization energy ε(+/-) or equivalently the standard hydrogen electrode energy, is considered to be an absolute energy reference for chemical bonding in the solid state.

    Processes active within sediment of the Bengal basin have attracted world concern because of the locally high content of arsenic dissolved in ground water drawn from that sediment. Sediment samples were collected from a borehole in the town of Rajoir, Rajoir upazila, Madaripur district, Bangladesh, to investigate the processes contributing to arsenic contamination. The samples were mineralogically and chemically analyzed to determine compositional variations related to the arsenic content of the sediment. Mineralogy of the sediment was determined using powder X-ray diffraction. Bulk chemical composition was measured by Combustion; Inductively Coupled Plasma Atomic Emission Spectroscopy; Energy Dispersive X-ray Fluorescence; and Hydride Generation Atomic Absorption Spectrophotometry. Sediment was treated with 0.5 N HCl and resulting solutions were analyzed, primarily to evaluate the abundance and oxidation state of acid-soluble iron. Acid-volatile sulfide, acid-soluble sulfate, and reducible sulfide were also measured on a few samples. Sediment sampled at Rajoir is typically unlithified, gray, micaceous, feldspathic arenaceous sand with a few silt and clay layers. Arsenic content of the sediment ranges from 0.6 to 21 ppm with a median of 1.2 ppm.

    The fluorescence from optically excited Ag atoms in Ar, Kr, and Xe matrices has been investigated in a time-resolved synchrotron-radiation study. A detailed energy dissipation model could be established from a systematic analysis of rise and decay times of all the observed fluorescence bands after pulsed excitation into the Ag (4d105p)2P1/2,3/2 levels, and by setting time windows between the excitation pulses in emission and emission-yield spectroscopy. Although the overall wavelength dependence of the decay time follows the λ3 law, the decay time is independent of λ within a given emission band. Finally, the role of energy transfer between Ag atoms and dimers for the evaluation of decay times is briefly addressed.
